Description

Technical Field

[0001] The utility model relates to the technical field of pick-and-place machines, in particular to a pick-up device for pick-and-place machine operation. Background Art

[0002] The pick-up device for pick-and-place machine operation is a component for automatic material picking of a pick-and-place machine, usually composed of a nozzle, a nozzle seat and a nozzle connecting pipe. The nozzle sucks and positions components onto the PCB board through the suction system of the pick-and-place machine to complete chip mounting. This device is an important part of the pick-and-place machine.

[0003] The existing pick-and-place machine nozzle is installed on the pick-and-place machine head through a quick-release joint on the nozzle. When the pick-up nozzle picks components of different sizes and batches, it is necessary for the staff to disassemble and replace the pick-up nozzle. The existing disassembly method is to use a screwdriver to loosen the screw of the nozzle mounting seat against the sliding limit groove on the surface of the nozzle, and then remove and replace the nozzle. Since there are multiple groups of pick-up nozzles installed on the pick-and-place machine head and the number of screws is large, the disassembly and assembly are relatively slow. Therefore, a pick-up nozzle structure for pick-and-place machine operation that improves the disassembly and replacement efficiency is proposed. Summary of the Utility Model

[0004] In view of the deficiencies of the existing technology, the utility model provides a pick-up device for pick-and-place machine operation, which is used to solve the problems of a large number of screws and slow disassembly and assembly of the existing pick-up nozzle for pick-and-place machine operation.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A pick-up device for pick-and-place machine operation includes a nozzle mounting seat body, a quick-release joint arranged on the top of the nozzle mounting seat body, and a plug-in seat arranged on the bottom of the nozzle mounting seat body. The lower end of the plug-in seat is movably plugged with a nozzle. A compression spring that is movably sleeved on the surface of the nozzle is arranged between the plug-in seat and the nozzle. A vertical limit groove is arranged on the outer wall of the nozzle. A fixed seat is arranged on the surface of the plug-in seat. A pin that horizontally movably penetrates through the fixed seat and the plug-in seat is arranged on the fixed seat. One end of the pin is movably plugged in the limit groove. A tension spring is arranged between the fixed seat and the pin. The two ends of the tension spring are respectively fixedly connected with the fixed seat and the pin.

[0007] Preferably, one end of the pin close to the limit groove is bullet-shaped.

[0008] Preferably, a pull ring is arranged at one end of the pin located outside.

[0009] Preferably, a ball bearing sleeve is inlaid on the fixed seat, and the pin is movably plugged in the ball bearing sleeve.

[0010] Compared with the existing technology, the utility model has the following beneficial effects:

[0011] By providing a bolt and a tension spring, when replacing the nozzle, the bolt can be pulled to separate it from the inner part of the limit slot, and then the nozzle can be pulled out downward from the socket for replacement. After replacement, the bolt can be reinserted, and the bolt can be locked by the tension spring. There is no need to use tools to disassemble and assemble screws, and it can be operated by hand, which is simple and fast, improving the replacement speed and solving the problem that the existing pick-and-place machine has a large number of screws for the feeding nozzle and slow disassembly and assembly speed.
