[0038] like Figures 1 to 15 As shown, this embodiment provides a PCB board terminal assembly pin device, which is used to transport terminal strip 100 and insert the terminals on the terminal strip 100 into the PCB board 200. Here, several terminals are provided on the terminal strip 100, and the terminals are inserted one by one.

[0039] In this embodiment, the PCB board terminal assembly platform includes a workbench 1, a pin insertion module support frame 2 mounted on the workbench 1, a terminal pin feeding module 3 mounted on the pin insertion module support frame 2 and the workbench 1, a PCB board platform 5 mounted on the workbench 1 and supporting the PCB board 200, a waste collection mechanism 6 connected to the terminal pin feeding module 3, an industrial control computer 4 and a CCD image acquisition mechanism 7 fixed on the pin insertion module support frame 2. The CCD image acquisition mechanism 7 faces the PCB board 200 on the PCB board platform 5. Furthermore, this embodiment utilizes the terminal pin feeding module 3 to transport the terminal strip 100 and inserts the terminals on the terminal strip 100 one by one onto the PCB board 200.

[0040] Specifically, the terminal insert module 3 includes a terminal strip flow channel 31 and a terminal strip feeding mechanism 32 fixed on the workbench 1, and a terminal insert module 33 fixed on the insert module support frame 2 and linked to the terminal strip feeding mechanism 32. The terminal strip feeding mechanism 32 pushes the terminal strip 100 into the terminal strip flow channel 31, and the terminal insert module 33 inserts the terminals on the terminal strip 100 into the PCB board 200. The terminal strip feeding mechanism 32 includes a first sliding module 321 fixed on the workbench 1, a pusher plate 322 connected to the first sliding module 321, a dispensing and pushing cylinder 323 disposed on the pusher plate 322, a pushing linkage plate 324 connected to the dispensing and pushing cylinder 323, and a pusher head 325 disposed at the front end of the pushing linkage plate 324 and inserted into the terminal strip 100. The pusher head 325 drives the terminal strip 100 to move.

[0041] In this embodiment, the terminal pin module 33 includes a pin mounting box 331 fixed on the pin module support frame 2, and a pin clamping drive mechanism 332, a pin pushing drive mechanism 333, and a pin actuation mechanism 334 disposed on the pin mounting box 331. Here, the pin clamping drive mechanism 332 is linked to the pin actuation mechanism 334 and clamps the terminals on the terminal strip 100. At the same time, the pin pushing drive mechanism 333 is linked to the pin actuation mechanism 334 and inserts the terminals on the terminal strip 100 into the PCB board 200.

[0042] In this embodiment, the pin clamping drive mechanism 332 includes a first motor 3321 fixed on the pin mounting box 331, a first rotating shaft passing through the pin mounting box 331 and connected to the first motor 3321, a first cam 3322, a second cam 3323, a third cam 3324 and a fourth cam 3325 sequentially arranged on the first rotating shaft, a first clamping actuator 3326 connected to the pin mounting box 331 in the middle by the rotating shaft and pressed against the first cam 3322 at the top, a second clamping actuator 3328 connected to the pin mounting box 331 in the middle by the rotating shaft, pressed against the third cam 3324 at the top and arranged opposite to the first clamping actuator 3326, a first clamping linkage mechanism 3327 connected to the pin actuator 334 and pressed against the second cam 3323, and a second clamping linkage mechanism 3329 connected to the pin actuator 334 and pressed against the fourth cam 3325.

[0043] In this embodiment, the first clamping actuator 3326 and the second clamping actuator 3328 clamp onto the terminal strip 100, that is, the first clamping actuator 3326 and the second clamping actuator 3328 clamp onto the second terminal at the foremost end of the terminal strip 100 or the terminal at the rear end of the second terminal. The first terminal at the foremost end of the terminal strip 100 is clamped by the pin insertion actuator 334, facilitating the insertion of the first terminal at the foremost end of the terminal strip 100 onto the PCB board 200. Here, the first clamping actuator 3326 and the second clamping actuator 3328 have the same structure. Taking the first clamping actuator 3326 as an example, it includes a swing arm 33261 that is axially sleeved on the lower side of the pin mounting box 331, a disc return spring disposed within the swing arm 33261 and positioned between the pin mounting box 331 and the swing arm 33261, and a first extrusion spring disposed on the upper part of the swing arm 33261 and pressed against the periphery of the first cam 3322. The device comprises a pressure roller 33262, a support slide 33264 fixed on the pin mounting box 331, a strip extrusion slide 33265 sleeved within the support slide 33264 with its front end facing the terminal strip 100, a first return spring 33266 disposed between the rear ends of the support slide 33264 and the strip extrusion slide 33265, and a second extrusion roller 33263 disposed at the lower part of the swing arm 33261 and extruding the rear end of the strip extrusion slide 33265. In this embodiment, the first clamping actuator 3326 and the second clamping actuator 3328 are used to clamp the terminal strip 100, preventing the second terminal at the front end of the terminal strip 100 and its rear end terminals from moving onto the PCB board along with the first terminal. This allows for sequential insertion.

Similarly, a second spring 33291 is disposed on the second clamping linkage mechanism 3329, so that the first clamping linkage mechanism 3327 and the second clamping linkage mechanism 3329 are tightly fitted against the second cam 3323 and the fourth cam 3325.

[0045] Here, after the first clamping linkage mechanism 3327 and the second clamping linkage mechanism 3329 drive the pin insertion actuator 334 to clamp the terminal at the foremost end of the terminal strip 100, the pin insertion drive mechanism 333 drives the pin insertion actuator 334 to perform the pin insertion operation.

The pin mounting box 331 has a slot, along which the fourth extrusion wheel 3334 slides.

[0046] In this embodiment, the pin clamping drive mechanism and the pin pushing drive mechanism drive the pin actuator 334 to clamp the terminal and perform the pin insertion operation. Here, the pin actuator 334 includes several second transverse sliding rail slider assemblies 3342 fixed laterally on the pin mounting box 331, a first transverse sliding plate 3343 and a second transverse sliding plate 3344 slidably disposed on the second transverse sliding rail slider assemblies 3342, a first longitudinal sliding rail assembly 3345 disposed on the first transverse sliding plate 3343, a first longitudinal pin pushing plate 3347 disposed on the first longitudinal sliding rail assembly 3345, a second longitudinal sliding rail assembly 3346 disposed on the second transverse sliding plate 3344, and a...
