The fully automatic double-ends wire crimping machine consists of three parts: the motion part, the control part and the execution part. wire crimping machine manufacturer said the wiring harness processing equipments on the market can be divided into three categories according to the accessories used at present.
1. Mechanical fully automatic double-ends wire crimping machine:
The main working principle is to drive the movement of the machine by belt and cam. The advantage is that the price is cheap, but the disadvantage is that the mechanical parts are easy to wear and age after using for a period of time, and the maintenance and debugging are troublesome. Short service life.
2. Stepping fully automatic double-ends wire crimping machine:
It mainly drives the movement of the machine through stepper motor.
The advantage is that the price is relatively low and the appearance is close to the servo motor. Compared with the mechanical design, it is more exquisite. The disadvantage is that the domestic ordinary step motor is easy to lose step and affects the precision of the product. The service life is short. The price difference between domestic stepper motor and imported famous brand servo motor is about 10 times. At present, more small companies use stepper motors as servo motors, declare that they are all servo products, or use some unknown servo plus some cam mechanical parts to deceive consumers.
3. Full-servo fully automatic double-ends wire crimping machine:
mainly through the PLC servo drive signal to control the movement of the servo motor, the advantages are high accuracy, long service life, high cost-effective, the disadvantage is that the price is more expensive, the use of motion modules together, greatly ensuring the accuracy and service life of the product.
The main functions of the reducer are as follows:
1. The reducer can reduce the moment of inertia. Generally, the square of speed ratio is reduced. It can control start-stop and speed change in time.
2. Increasing the torque through the reducer is equivalent to increasing the input power, which can reduce the power required by the input motor.
3. Reducer has the function of protecting motor in transmission. Reducer bears large torque in operation.fully enclosed gear reducer motor transmits only the value of overload divided by deceleration ratio when overload occurs. If it is directly borne by motor, it may cause motor damage.
4. When the motor is directly connected to the load at low speed, in order to meet the output torque current, the motor will increase a lot, which will inevitably have higher requirements for the heat dissipation and insulation of the motor. It is also undesirable from the point of view of energy saving. If the reducer is used, the impact of these problems can be reduced.
The role of the motor module:
1. Flexible movement without gap
2. Easy to obtain high walking accuracy
3. High positioning accuracy
4. High rigidity in all directions
5. High allowable load
6. Can maintain high accuracy for a long time
7. Excellent speed.

(1) Fully automatic wire crimping machine stamping guide rail must be added oil lubrication filling hole at the top of the terminal machine once an hour, each filling 2-3 drops should not be too much.
(2) Operators must clean the machine every day to remove dust and debris on the surface of the machine and excess oil pollution.
(3) Grease must be added to the main speed bearing of the automatic wire crimping machine every week.
The specific operation methods are as follows:
Opening the rear cover of the wire crimping machine
Removing the clip spring of driven pulley,
Removing pulley,
Smearing grease (uniformly applied on the surface of high speed bearing) and restoring (note: in the process of removing pulley, attention to bearing balls perhaps be lost).
After 3-6 months using the fully automatic wire crimping machine, it is necessary to check whether the parts (wearing parts) need to be replaced, such as belt, and whether the spring elasticity of each part needs to be replaced. Whether the locking screw of the machine is loose or not, check whether the clamp spring is deformed, etc.
Usually in the work, we not only need to know how to use the automatic terminal machine, but also need proper maintenance. Without maintenance, not only will reduce the life of the machine terminals, but also the maintenance skills of the automatic terminal machine will affect the efficiency of the machine.
Maintenance process of automatic terminal machine
1. (Stepping Principle) The motor keeps turning. There is an internal wrapped breaker with a clutch. Every step produces a standard “O” coming out, which is the most common.
2. In the last five years, there has been a mute wire crimping machine with a servo. Its operating principle is different from that above. It just gives the servo a message, which is then transmitted to the motor and acts as an action.
As long as the wire is worn, the applicator installed, production can start... read more

What causes bad contact of wire crimping machine? For machines, poor contact has always been one of the main causes of failure, from small mobile phones, large computers, larger end-to-end sub-machines or aviation equipment. Since this problem is so important, we must pay attention to it. Let Fortune Sky wire crimping machine manufacturer analyze the bad contact problem of wire crimping machine today.
For a computer, the most common malfunction is the memory chip. For a wire crimping machine, the most common malfunction is the metal conductor inside the terminal. This part is the core part of the terminal. It transmits the voltage, current or signal from external wires or cables to the contacts corresponding to its matching connectors.
Because of its importance, the wire crimping machine is required to have stable and reliable contact and good conductivity. So what factors will cause poor contact of wire crimping machine contact structure?
In fact, this is a common factor, such as excessive processing size, unreasonable surface treatment technology such as heat treatment and plating, poor storage environment, poor and improper use and operation, etc., may make contact parts and coordination parts of automatic wire crimping machine poor contact.
Common fatal faults at terminals?
1. Poor contact
The metal conductor inside the terminal is the core part of the terminal. It transmits the voltage, current or signal from the external wire or cable to the contacts corresponding to its matching connector. Therefore, the contact parts must have excellent structure, stable and reliable contact retention and good conductivity. Due to the unreasonable structure design, wrong material selection, unstable die, excessive processing size, rough surface, unreasonable surface treatment process such as heat treatment and electroplating, improper assembly, poor storage and use environment and improper operation, all of these will cause poor contact at the contact and coordination parts of the contact parts.
2. Poor insulation
The function of insulator is to keep the contacts in the correct position, and to protect the contacts from the contacts and the shells from each other by insulating the conveyor. Therefore, insulators must have excellent electrical performance, conveyor protection mechanical performance and process forming performance. Especially with the wide use of high density and miniaturized terminals, the effective wall thickness of insulators becomes thinner and thinner. This puts forward more stringent requirements for insulation materials, precision of injection moulds and moulding technology. Due to the existence of metal redundancy, surface dust, flux and other contaminations on the surface or inside of insulators, the amalgamation of organic material precipitates and harmful gas adsorption film with surface water film to form ionic conductive channels, moisture absorption, long mold, aging of insulating materials and other reasons, will cause short circuit, leakage, breakdown, low insulation resistance and other bad insulation phenomena.
3. Poor fixation
Insulators not only play an insulating role, but also provide precise centering and protection for extended contacts. They also have the functions of installation, positioning and locking and fixing on equipment. Poor fixing, light impact on contact reliability, resulting in instantaneous power failure, the serious is product disintegration. Disintegration refers to the abnormal separation between plugs and sockets and between pins and sockets caused by unreliable structure due to material, design, process and other reasons, which will result in serious consequences of power transmission and signal control interruption of computer stripper in control system. Due to unreliable design, wrong material selection, improper selection of forming process, poor quality of heat treatment, die, assembly, welding and other processes, inadequate assembly will cause poor fixation.
In addition, due to coating peeling, corrosion, bruising, plastic shell flying edge, rupture, rough contact parts processing, deformation and other reasons caused by poor appearance, due to positioning and locking with poor size, poor consistency of processing quality, total separation force and other reasons caused by poor interchange, is also a common disease, frequently occurring. These kinds of faults can be found and eliminated in time in the process of inspection and use.
