[0049] A base 21 is placed at the automatic pin insertion station 2, and a slide rail 221 is arranged on the base 21 along the length direction. Four pin clamps 222 are slidably connected to the slide rail 221, and each pin clamp 222 is fixedly connected to a pin clamp cylinder 224. The four pin clamps 222 are commonly connected to a moving block, and the moving block is slidably connected to the slide rail 221. A driving cylinder 223 is connected to the sliding block 253, and the driving rod of the driving cylinder 223 is axially arranged along the length direction of the slide rail 221. A vertical cylinder 225 is also connected to the lower end of the slide rail 221. The vertical cylinder 225 is fixedly connected to the base 21, and the driving rod of the vertical cylinder 225 is arranged in the vertical direction. The slide rail 221, the pin clamp 222, the driving cylinder 223, and the pin clamp cylinder 224 together constitute a handling module 22 for transporting the rubber disc base. An automatic needle insertion machine 23 and a needle pressing machine 24 are fixedly connected to one side of the slide rail 221 . The automatic needle insertion machine 23 involved in this embodiment is a standard machine and will not be described in detail here. A transfer device 25 is provided between the slide rail 221 and the automatic needle insertion machine 23 .

[0050] The transfer device 25 includes an X-axis seat 251 and a Y-axis seat 255 arranged in a cross shape. The X-axis seat 251 is fixedly connected to the base 21. An X-axis slide groove 252 is provided on the X-axis seat 251, and a sliding block 253 is slidably connected in the X-axis slide groove 252. An X-axis motor 254 is fixedly connected to the X-axis seat 251. A screw is coaxially fixedly connected to the driving rod of the X-axis motor 254.

The screw penetrates the lower end of the bearing seat 257 and is threadedly connected to the bearing seat 257. When the rubber disc base passes through the transfer device 25, the pin clamp 222 is released, so that the rubber disc base falls on the supporting seat 257, and the X-axis motor 254 drives the Y-axis seat 255 to move to the automatic pin insertion machine 23, and adjusts the position of the supporting seat 257 through the Y-axis motor 258, and then the automatic pin insertion machine 23 starts to insert the pin. After the pin insertion operation is completed, it returns to the original path and is re-grabbed by the pin clamp 222 and continues to move along the slide rail 221.

[0051] The Y-axis seat 255 is also fixedly connected with a stabilizing cylinder 259, the driving rod of which is arranged in the vertical direction, and the driving rod of the stabilizing cylinder 259 is fixedly connected with a bent L-shaped stabilizing rod, one end of which is located above the bearing seat 257. When the rubber disc base is placed in the bearing seat 257, the stabilizing cylinder 259 drives the stabilizing rod to press down to stabilize the rubber disc base, reduce the possibility of displacement of the rubber disc base in the bearing seat 257, and improve stability.

[0054] A cleaning seat 261 is fixedly connected to one side of the semi-finished product assembly line 8, and a cleaning block 263 is slidably connected to the cleaning seat 261. The cleaning block 263 is located above the semi-finished product assembly line 8 in the vertical direction. A cleaning cylinder 262 is fixedly connected to the top of the cleaning seat 261. The driving rod of the cleaning cylinder 262 is axially arranged in the vertical direction. The cleaning block 263 is coaxially fixedly connected to the driving rod of the cleaning cylinder 262. A ventilation pipe 264 is inserted through the cleaning block 263. The air outlet of the ventilation pipe 264 is arranged toward the semi-finished product assembly line 8, and the air inlet of the ventilation pipe 264 is connected to the outside. During the processing, the air inlet of the ventilation pipe 264 is connected to the air supply pipe. When the semi-finished connector with a pin needle passes through the cleaning seat 261, the cleaning cylinder 262 drives the cleaning block 263 to sink, and the air supply pipe blows air onto the semi-finished connector through the ventilation pipe 264, thereby achieving a cleaning effect with the help of the cleaning module 26 composed of the cleaning seat 261, the cleaning cylinder 262, the cleaning block 263, and the ventilation pipe 264.
