[0033] Refer to Figure 1 andFigure 2 As shown in the figure, an opening device 10 for a VCP fixture is provided in an embodiment of the present utility model. The VCP fixture 20 includes a fixed fixture 21, a movable fixture 22, and a tensioning device 23. The movable fixture 22 is movably connected to the fixed fixture 21, and the tensioning device 23 is used to lock the movable fixture 22 and the fixed fixture 21. The opening device 10 includes a mounting frame 100, an opening assembly, and a reset assembly 300. The opening assembly is connected to the mounting frame 100 and is used to release the tensioning device 23. The reset assembly 300 is connected to the mounting frame 100 and is used to drive the movable fixture 22 to move relative to the fixed fixture 21.

[0034] When the opening device 10 of this embodiment is used in cooperation with the VCP fixture 20, by setting the opening assembly and the reset assembly 300 to drive the tensioning device 23 of the VCP fixture 20, stable and controllable opening and reset adjustment of the tensioning device 23 in the VCP fixture 20 can be performed, thereby effectively improving the reliability of the tensioning device 23.

[0035] Specifically, the tensioning device 23 includes a claw 2301 and a tensioning fixture 2302. The claw 2301 is movably connected to the fixed fixture 21, the tensioning fixture 2302 is connected to the movable fixture 22, and the claw 2301 is in clamping engagement with the tensioning fixture 2302. The opening assembly is used to drive the claw 2301 to rotate relative to the fixed fixture 21 so that the claw 2301 releases the tensioning fixture 2302, and the reset assembly 300 is used to drive the tensioning fixture 2302 to move relative to the fixed fixture 21.

[0036] In this embodiment, a plurality of card slots are sequentially arranged on one side of the tensioning fixture 2302 facing the claw 2301 along the length direction of the movable fixture 22. The claw 2301 is connected to the fixed fixture 21 through an elastic member and is driven by the elastic force of the elastic member to be in clamping engagement with the card slots on the tensioning fixture 2302 to position the lengths of the fixed fixture 21 and the movable fixture 22. By starting the opening assembly, the claw 2301 can be driven to rotate and release the tensioning fixture 2302. At this time, by starting the reset assembly 300, the movable fixture 22 can be driven to move relative to the fixed fixture 21 to achieve the adjustment function.

[0037] In one embodiment, the opening assembly includes an opening cylinder 210 and an opening dial 220. The opening cylinder 210 is arranged on the mounting frame 100, and the opening dial 220 is connected to the output end of the opening cylinder 210. The opening cylinder 210 is used to drive the opening dial 220 to abut against the claw 2301 and drive the claw 2301 to rotate relative to the fixed fixture 21.

[0038] With this setting, by activating the clamping cylinder 210 to drive the clamping plate 220 to move in a direction away from the clamping cylinder 210, when the clamping plate 220 abuts against the end of the claw 2301, the other end of the claw 2301 can be driven to move in a direction away from the tensioning fixture 2302, so as to release the card slot of the tensioning fixture 2302, and thus the release action of the clamping assembly can be completed.

[0039] Specifically, the number of the tensioning devices 23 is two groups, and the two groups of tensioning devices 23 are symmetrically arranged. The number of the clamping plates 220 is also two, and the two clamping plates 220 are respectively matched with the two groups of tensioning devices 23.

[0040] In this embodiment, the clamping cylinder 210 is a two-way cylinder, and the two output ends of the clamping cylinder 210 can drive the two clamping plates 220 to move towards or away from each other simultaneously, so that the two clamping plates 220 can release the two claws 2301 simultaneously; by arranging two groups of tensioning devices 23 to cooperate with the fixed fixture 21 and the movable fixture 22, the limit reliability and force balance degree of the tensioning device 23 can be improved.

[0041] In one embodiment, the reset assembly 300 includes a reset cylinder 310 and a reset pressing plate 320. The reset cylinder 310 is connected to the mounting frame 100, the reset pressing plate 320 is connected to the output end of the reset cylinder 310.

[0042] In this embodiment, by arranging the cooperation of the reset cylinder 310 and the reset pressing plate 320, after the clamping assembly releases the limiting effect on the claw 2301, the reset cylinder 310 drives the reset pressing plate 320 to move relative to the fixed fixture 21. At this time, by contacting the reset pressing plate 320 with the tensioning fixture 2302, the tensioning fixture 2302 can be driven to move relative to the fixed fixture 21, and thus the movable fixture 22 can be driven to move relative to the fixed fixture 21 to perform a tensioning operation on the PCB board on the VCP fixture 20.

[0043] Furthermore, the reset assembly 300 further includes a reset guide rod 330 and a reset connecting frame 340. The reset cylinder 310 is connected to the reset connecting frame 340, and the reset guide rod 330 is connected to the reset connecting frame 340 and is slidably matched with the mounting frame 100.

[0044] By arranging the cooperation of the reset guide rod 330 and the reset connecting frame 340, the smoothness of the movement of the reset pressing plate 320 relative to the mounting frame 100 can be improved, thereby improving the control accuracy and operation stability of the clamping device 10.

[0045] In a preferred embodiment, the number of the tensioning devices 23 is two groups, and the two groups of tensioning devices 23 are symmetrically arranged. The number of the reset pressing plates 320 is also two, and the two reset pressing plates 320 are respectively matched with the two groups of tensioning devices 23.

[0046] In this embodiment, by arranging two groups of tensioning devices 23 to cooperate with the fixed fixture 21 and the movable fixture 22, the limit reliability and force uniformity of the tensioning devices 23 can be improved; when the reset cylinder 310 is started, the two reset pressing plates 320 can be driven to move relative to the mounting frame 100 at the same time. Thus, the two reset pressing plates 320 can respectively cooperate with the tensioning fixtures 2302 on both sides, thereby improving the smoothness and stability of the reset assembly 300 driving the movable fixture 22 to move relative to the fixed fixture 21.

[0047] Furthermore, the clamping device 10 further includes an adjusting assembly 400. The adjusting assembly 400 is connected to the mounting frame 100 and is used to drive the mounting frame 100 to move relative to the VCP fixture 20.

[0048] With this setting, the adjusting assembly 400 can drive the clamping assembly and the reset assembly 300 to move relative to the VCP fixture 20, so as to adjust the positions of the clamping dial 220 relative to the claw 2301 and the reset pressing plate 320 relative to the tensioning fixture 2302. By cooperating with sensors, the automatic control function of the clamping device 10 can also be realized, thereby improving the adjustment accuracy of the clamping device 10.

[0049] Specifically, the adjusting assembly 400 includes an adjusting cylinder 410 and an adjusting slide rail 420. The mounting frame 100 is connected to the output end of the adjusting cylinder 410, and the adjusting slide rail 420 is slidably connected to the mounting frame 100.

[0050] In this embodiment, by starting the adjusting cylinder 410, the mounting frame 100 can be driven to move in a direction close to or away from the VCP fixture 20. By arranging the adjusting slide rail 420 to be connected to the mounting frame 100, the movement of the mounting frame 100 can be guided to improve the movement accuracy and smoothness of the mounting frame 100.

[0051] During the application process of the clamping device 10, after the VCP fixture 20 completes the loading and unloading positioning action of the PCB, the adjusting assembly 400 can drive the mounting frame 100 to move towards the VCP fixture 20, and make the clamping assembly and the reset assembly 300 respectively cooperate with the claw 2301 and the tensioning fixture 2302 to complete the reset action; after the reset action is completed, the adjusting assembly 400 controls the mounting frame 100 to move in the reverse direction to reset, so as to prepare for the next action.
