Problems solved by technology

Connectors and PCB boards generally adopt the structure of pins and pinholes. The working principle of the crimping machine is to press the pins of the connector into the pinholes of the PCB board, so that the connector is connected to the PCB board; however, the actual production and manufacturing In the process, the crimping machine does not work alone, but is designed on the PCB board production line as a process in the PCB board production process. Therefore, the interaction between the transportation process of the PCB board and the crimping process of the crimping machine The connection and cooperation directly affect the crimping efficiency and crimping quality of the entire crimping machine; in addition, the connector and the PCB generally adopt a pin-to-pin hole matching structure. The installation accuracy is high. In the actual crimping process, due to factors such as assembly errors and displacement caused by vibration during the transmission process, the position of the indenter and the connector pins deviate, which may easily lead to damage to the connection during later crimping. In addition, in actual production and processing, the form and structure of connectors are ever-changing, with different application objects, frequencies, power, application environments, etc., there are various types of connectors, for different connector needs Setting multiple different crimping heads requires replacement of different crimping heads in the process of crimping different connectors. The replacement of multiple crimping heads wastes time and labor and affects crimping efficiency; in addition, in the actual crimping process, crimping When the head part is crimping the connector pins, the following situations will occur: 1. During the automatic working process of the crimping machine, the connector on the PCB board will be missed. At this time, if the crimping head continues to crimp the PCB board , then it is directly crimped on the PCB board, resulting in damage to the PCB board; 2. The pinhole on the PCB board is too large, or the pin diameter of the connector is too small, which will lead to unstable connection between the pin and the pinhole after crimping 3. Since it is an instant action for the crimping head to press the pin into the pinhole, the connection is made firm through the deformation of the pin. Therefore, the excessive deformation of the pin during the crimping process will cause the material layer of the pin to break and make the connection invalid. And after the crimping is completed, the pins have deformation and rebound, which also leads to connection failure; 4. During the crimping process of the connector, there will be kneeling pins. After kneeling, the pins are bent and broken, and cannot be inserted into the pinholes. If the crimping head continues to crimp downward, it will be directly pressed to the PCB board, resulting in damage to the PCB board; 5. During the replacement of the indenter parts, there is a missing installation, resulting in the crimping assembly not being installed with the indenter parts; 6. In actual work, there may be abnormal conditions in the stroke of the indenter moving down from the Z-axis zero point to the connector and the motion stroke inserted into the connector, and it is necessary to stop the movement in time; 7. In addition, during the crimping process, the crimping Stroke control is based on the detected PCB board thickness and measured liner thickness as theoretical data. The actual PCB board thickness detection and liner installation errors will lead to too large or too small crimping according to the theoretical data, resulting in PCB board crushing Or the crimping is not in place
