A conveying mechanism 33 is provided on one side of the placement plate 31, and the conveying mechanism 33 is used to complete the transmission of the material strip from the raw material shaft 21 to the cutting mechanism 32.

[0042] like Figure 1-4 As shown, the cutting mechanism 32 includes a first base plate 321, on which a first vertical plate 322 and a second vertical plate 323 are arranged opposite to each other, and a guide column 324 is connected between the first vertical plate 322 and the second vertical plate 323, and the guide column 324 is arranged horizontally. A movable cutting fitting 325 is sleeved on the guide column 324, and the cutting fitting 325 is connected to a first telescopic cylinder 326. The first telescopic cylinder 326 is operated to drive the cutting fitting 325 to reciprocate between the first vertical plate 322 and the second vertical plate 323 to complete the cutting of the material strip.

[0043] like Figure 1-5As shown, the first vertical plate 322 includes a receiving portion and a processing portion sequentially arranged along the conveying direction of the material strip, and the receiving portion has a receiving groove 3221 opened along the length direction, which is used to receive the material strip conveyed from the placement groove 311. The processing portion includes an open groove 3222 opened along the width direction of the first vertical plate 322, and a step 3223 is arranged below the open groove 3222. The step 3223 is connected to the receiving groove 3221 and is used to place the material strip. Among them, the end surface of the step 3223, the bottom of the receiving groove 3221 and the bottom of the placement groove 311 are all located on the horizontal line of the same height to achieve the smooth conveying of the material strip. The width of the end of the opening groove 3222 close to the second vertical plate 323 is adapted to the width of the connector, so that the connector can be placed at the position of the opening groove 3222, and the terminals on both sides of the connector are correspondingly attached to the side walls of the first vertical plate 322, which is convenient for completing the cutting of the connector at the position of the opening groove 3222. Preferably, the height of the side of the opening slot 3222 away from the second vertical plate 323 is lower than the height of the side close to the second vertical plate 323, so that the opening slot 3222 has a certain slope, which is convenient for chip removal and prevents the cut connectors from accumulating in the opening slot 3222; and the horizontal width of the side of the opening slot 3222 away from the second vertical plate 323 is greater than the horizontal width of the side close to the second vertical plate 323, so as to expand the space in the opening slot and buffer the waste discharge process.

Preferably, an upper baffle 327 is correspondingly provided on the opening slot 3222 to prevent the debris generated during the punching force from splashing.

[0044] like Figure 1-6 As shown, the cutting fitting 325 includes a first stamping plate 3251 and a second stamping plate 3252 connected to each other through an elastic member 3253. In this embodiment, the first stamping plate 3251 is between the first vertical plate 322 and the second stamping plate 3252, and the second stamping plate 3252 is connected to the push rod of the first telescopic cylinder 326. A punching head 3254 is arranged on the side of the second stamping plate 3252 close to the first stamping plate 3251, and a punching channel 3255 is correspondingly provided through the first stamping plate 3251, and a part of the punching head 3254 is placed in the punching channel 3255. When the elastic member 3253 is in a compressed state, the end of the punching head 3254 protrudes from the side of the punching channel 3255 away from the second stamping plate 3252, that is, the punching head 3254 can push the connector out from between the terminals on both sides. Preferably, the first punching plate 3251 is provided with abutment plates 3256 on one side close to the first vertical plate 322, and the abutment plates 3256 are correspondingly arranged on both sides of the punching channel 3255. During the punching process, the abutment plates 3256 are pressed against the terminals on both sides to fix the terminals, and the punching head 3254 extends out to punch the connector from the opening of the opening slot 3222.

[0045] like Figure 1-6 As shown, preferably, a first positioning pin 3257 is provided on one side of the first stamping plate 3251 close to the first vertical plate 322, and a first positioning hole 3224 is correspondingly provided on the first vertical plate 322, and the first positioning pin 3257 can be correspondingly inserted into the first positioning hole 3224. When the PIN needle material strip is being transferred in the receiving groove 3221, the punching hole of the connector can be correspondingly placed in the first positioning hole 3224. When the first positioning pin 3257 is correspondingly inserted into the punching hole through the first positioning hole 3224, the connector of the processing part is correspondingly placed in the middle of the opening groove 3222 to ensure that the transmission stop position of the material strip is accurate and the terminal cutting is accurate.

[0046] like Figure 1-7 As shown, a conveying mechanism 33 is provided on one side of the placement plate 31, which is used to push the material strip from the placement plate 31 to the cutting mechanism 32. The conveying mechanism 33 includes a first connecting plate 332 and a first transverse cylinder 331 for driving the first connecting plate 332 to move along the length direction of the placement plate 31. A second telescopic cylinder 333 is correspondingly provided on the first connecting plate 332. The output end of the second telescopic cylinder 333 faces the placement plate 31 and is connected to a pushing member 334. A pushing rod 335 is arranged on the side of the pushing member 334 close to the placement plate 31. A pushing groove 312 is provided at the placement plate 31 corresponding to the position of the pushing rod 335. The pushing groove 312 extends along the length direction of the placement plate 31 and is connected to the placement groove 311. The height of the pushing groove 312 is adapted to the height of the punching hole of the material strip. When the PIN needle material strip is placed in the placement plate 31, the pushing rod 335 can pass through the pushing groove 312 and be correspondingly inserted into the punching hole.

[0047] like Figure 1-7 As shown, preferably, the first connecting plate 332 is slidably disposed on the first slide rail through a slider, and the first slide rail and the placement plate 31 are parallel to each other to improve the stability of the first connecting plate 332 during movement. Limiting members are provided at both ends of the first slide rail to control the sliding stop position of the first connecting plate 332. Preferably, the lower end of the push member 334 is slidably disposed on the second slide rail through a slider, and the second slide rail and the placement plate 31 are perpendicular to each other to improve the stability of the push member 334 during movement. A limiting protrusion is provided on one end of the first connecting plate 332 close to the placement plate 31, and a matching protrusion is correspondingly provided on the side of the push member 334. When the push member slides toward the placement plate, the matching protrusion abuts against the limiting protrusion to control the sliding stop position of the push member.

[0048] like Figure 1-8As shown, a positioning mechanism 34 is also provided on one side of the placement plate 31. The positioning mechanism 34 includes a second base plate 341. A third telescopic cylinder 342 is provided on the second base plate 341. The output end of the third telescopic cylinder 342 faces the placement plate 31 and is connected to a positioning base plate 343. The positioning base plate 343 has a second positioning pin 344 and a proximity sensor 345. The proximity sensor 345 is correspondingly provided on the side of the second positioning pin 344 away from the placement plate 31. The second positioning pin 344 is connected by a spring. A positioning groove 313 is provided on the side of the placement plate 31 close to the positioning mechanism corresponding to the position of the second positioning pin. The second positioning pin 344 can be inserted into the positioning groove 313 under the push of the third telescopic cylinder 342. The height of the positioning groove 313 is adapted to the height of the punching hole. When the punching hole is not aligned with the positioning groove 313, the second positioning pin 344 moves toward the mounting plate 31 and cannot be inserted into the punching hole. One end thereof abuts against the side wall of the terminal and cannot continue to move forward. At the same time, the proximity sensor 345 continues to move forward and contacts the second positioning pin 344. The proximity sensor 345 thereby issues a prompt that the PIN needle strip is not positioned correctly.

[0049] like Figure 2 As shown, in this embodiment, a guiding unit is arranged between the discharging unit and the processing unit, and the guiding unit includes a first guiding part 41 and a second guiding part 42 arranged in sequence along the transmission direction, which are used to guide the transmission direction of the material belt and control the position of the material belt.

The PIN needle material strip can pass between the first guide wheel 412 and the second guide wheel 413, thereby limiting the transmission route of the PIN needle material strip.

[0051] like Figure 1-10 As shown, the second guide part 42 includes a second support frame 421, which is arranged at one end of the placement plate 31 close to the discharge unit, and a support step 422 is arranged on the second support frame 421 for placing the PIN needle material strip.
