A spring 306 is provided on the outer sleeve of the plug post 305, and one end of the spring 306 is in contact with the grounding horizontal plate 302, and the other end is in contact with the base.

[0036] The specific working steps are as follows: each blank is fixed to the bottom plate 5 by bolts, and a pull rod 50 is provided on the bottom plate 5. Before working, the pull rod 50 on the bottom plate 5 is used to cooperate with the socket 404 on the transport trolley 212, so that the blank and the bottom plate 5 are assembled on the transport trolley 212. Each trolley is numbered, for example, the shoe mold that needs to be processed into size 39 is placed on trolley No. 1, and the shoe mold that needs to be processed into size 38 is placed on trolley No. 2. After the blank is assembled, the information that trolley No. 1 is for processing shoe mold No. 39 and trolley No. 2 is for processing shoe mold No. 38 is input into the host PLC controller. The workbench 20 starts working, and the conveyor chain 203 is driven by the motor and gear 204 to perform circumferential circular motion. When trolley No. 1 moves to the pick-up point 200, the sensor 23 senses the arrival of trolley No. 1 and transmits the signal to the host PLC controller. The host PLC controller commands the robot arm 31 to move to the position of the pick-up point 200 and transports the blank on trolley No. 1 to the slave machine 1 of the CNC machining equipment 4. The staff can load the empty trolley No. 1 at the loading point 201 and reinstall the new blank.

[0037] The host PLC controller sends the work information of the size 39 shoe mold to the slave PLC controller of slave 1. After the manipulator grabs the bottom plate 5 and the blank, the pull rod 50 on the bottom plate 5 is inserted into the socket 404 of the chuck body 401, and the limit ring 500 on the pull rod 50 is inserted into the circular opening of the latch 405. After the magnetic proximity switch 411 on the chuck body 401 senses the base, the oil cylinder is controlled to work, and the oil cylinder drives the latch 405 to move, and the straight opening on the U-shaped opening 406 is moved to the position of the limit ring 500 of the pull rod 50. The limit ring 500 follows the guidance of the inclined plane 1 409 and enters between the two inclined planes 2 410. As the distance between the two inclined planes 1 409 and the two inclined planes 2 410 gradually decreases, the limit ring 500 will be stuck on the latch 405, and the latch 405 will fix the position of the pull rod 50, thereby improving the structural stability of the bottom plate 5 on the chuck body 401. Slave machine 1 will work on the blank. When slave machine 1 completes the process, the slave PLC controller on slave machine 1 will sense slave machine 2 to determine whether it is in working state. When slave machine 2 is not in working state, the slave PLC controller will send a signal to complete the process. After the host PLC controller senses the completion signal, it controls the mechanical arm 31 to move to the position of slave machine 1. After the sensor 2 412 on the chuck body 401 senses the completion signal of slave machine 1, it controls the oil cylinder to work, so that the circular ring 407 on the latch 405 moves to the position of the limit ring 500 of the pull rod 50. The pull rod 50 is in an unclamped state. The mechanical arm 31 can remove the bottom plate 5 and the blank from slave machine 1 and transport them to the slave machine for work. When the blank completes the process in slave machine 2, it is transported to slave machine 3 by the mechanical arm 31 for work. After the process is completed in slave machine 3, the mechanical arm 31 moves to slave machine 4 for work, and then the finished shoe mold is obtained. Finally, the robot arm 31 transports the finished shoe mold to the unloading chain 25 of the workbench 20, and the gear 26 drives the unloading chain 25 to move in a circular motion. The unloading chain 25 drives the finished shoe mold to be transported toward the other end of the workbench 20. The staff can sort and unload the finished shoe mold at the other end of the workbench 20. The unloading chain 25 can play the role of temporarily storing goods to avoid damage caused by random stacking of finished products. It is convenient for the staff to sort out the finished products in an orderly manner and improve the work quality of unloading.

[0038] The length of the workbench 20 and the number of transport carts 212 can be adjusted according to the use requirements of the workshop. The number of CNC processing equipment 4 can also be adjusted according to the actual production volume. It is convenient to improve the work efficiency of the entire production line, while improving the degree of automation, and reducing the output of manual labor. When slave machine 2 is processing the blank, the robot arm 31 can transport the blank on the No. 2 transport cart 212 to slave machine 1 to work simultaneously with slave machines 2, 3 and 4. This can greatly improve the work efficiency of the entire production line.

[0039] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
