[0033] The following is combined with Figure 1-9 This application is described in further detail.

[0034] The embodiment of the present application discloses a clamping mechanism. Figure 1 The clamping mechanism includes at least two groups of clamping components 1 and adjusting components 2. The clamping components 1 are used to clamp the product. In this embodiment, two groups of clamping components 1 are set, and are arranged relative to each other, and different clamping components 1 are set at intervals; the adjusting components 2 are used to adjust the spacing between the clamping components 1.

[0035] Each group of clamping assemblies 1 includes at least two clamping members 11 and fixing members 12. The clamping members 11 are used to clamp the product. In this embodiment, four clamping members 11 are provided, which are respectively clamped at the four corners of the product. The distance between the clamping members 11 in the same group is adjusted by the fixing members 12 so that it can adapt to different products.

[0036] Reference Figure 2In this embodiment, the clamping member 11 includes a clamping base 111, a clamping cylinder 112, a connecting member 113, a rotating member 114 and a movable rod 115. The clamping cylinder 112 is screwed to the clamping base 111, and the output end of the clamping cylinder 112 is fixedly connected to the connecting member 113. The rotating member 114 is rotatably connected to the connecting member 113. Both sides of the clamping base 111 are provided with an inverted "V"-shaped movable groove 116 for guiding the rotation direction of the rotating member 114. The movable rod 115 passes through the connecting member 113, and the two ends of the movable rod 115 are respectively inserted into the movable grooves 116 on both sides. When the clamping cylinder 112 pulls back the rotating part 114, the rotating part 114 rotates along the movable groove 116 away from the clamping base 111. At this time, the product can be placed on the clamping base 111, and then the rotating part 114 is pushed out by the clamping cylinder 112. The rotating part 114 rotates along the movable groove 116 close to the clamping base 111. At this time, the rotating part 114 cooperates with the clamping base 111 to clamp the product, and the product can be stamped.

[0037] Reference Figure 3 and Figure 4 In some embodiments, the fixing member 12 includes a guide block 121, a guide rod 122, and a second cylinder 123. The guide block 121 is provided with a guide hole 124, which is used to guide the moving direction of the guide rod 122. One end of the guide rod 122 is connected to the clamping member 11 by screwing, and the other end passes through the guide hole 124 and is slidably connected to the guide block 121. The output end of the second cylinder 123 faces the guide rod 122. When the output end of the second cylinder 123 abuts against the guide rod 122, the guide rod 122 is abutted and fixed. When the clamping member 11 needs to be moved, the guide rod 122 is moved along the direction of the guide hole 124. When it is moved into position, the output end of the second cylinder 123 abuts and fixes the guide rod 122, so that the position of the clamping member 11 is fixed.

[0038] In some embodiments, the guide block 121 further defines a fixing groove 125, which is interconnected with the guide hole 124. The output end of the second cylinder 123 is screwed to a second abutting block 126, which defines a second abutting groove. The groove wall of the second abutting groove has a curvature consistent with the curvature of the side wall of the guide rod 122. When the guide rod 122 needs to be fixed, the second cylinder 123 drives the second abutting block 126 to be inserted into the fixing groove 125 until the groove wall of the second abutting groove abuts the guide rod 122, thereby more stably fixing the guide rod 122 and, therefore, more stably fixing the clamping member 11.

[0039] Refer again Figure 2In some embodiments, the clamping mechanism further includes a third cylinder 3, which drives the clamping members 11 in the same group toward or away from each other. In this embodiment, the third cylinder 3 is threadedly connected to a third base 4, which is fixedly connected to the guide rod 122. Moving the guide rod 122 drives the third base 4 to move, thereby driving the third cylinder 3 and the clamping members 11 to move together. The third cylinder 3 is used to fine-tune the clamping members 11, allowing the clamping members 11 to clamp the product more stably through fine-tuning of the third cylinder 3.

[0040] In some embodiments, the clamping mechanism further includes a fourth cylinder 5, which drives different groups of clamping members 11 to move closer to or away from each other. In this embodiment, the fourth cylinder 5 is screwed to the fourth base 6, the clamping member 11 is slidably connected to the fourth base 6, and the output end of the fourth cylinder 5 is screwed to the clamping member 11. The fourth cylinder 5 is used to fine-tune the distance between the two groups of clamping assemblies 1; the output end of the third cylinder 3 is screwed to the fourth base 6, and the third cylinder 3 drives the fourth base 6 to drive the fourth cylinder 5 and the clamping member 11 to move; when the clamping member 11 clamps the product, the third cylinder 3 and the fourth cylinder 5 fine-tune the clamping member 11, so that the clamping member 11 can stretch the product, making the product flatter, so that the product can be better punched, ensuring the punching quality of the product.

[0041] Reference Figure 5 , the adjustment component 2 includes a support member 21, a fastener 22 and a fitting member 23. In this embodiment, the support member 21 is a plate-like structure. The support member 21 corresponds one-to-one to the clamping component 1, and the clamping component 1 is respectively installed on the support member 21. In this embodiment, the fourth base 6 is screwed to the support member 21, so that the clamping member 11 is installed on the support member 21. The fitting member 23 is installed on the support member 21. In this embodiment, the fitting member 23 is screwed to the support member 21. The fastener 22 is in a fixed state, that is, the fastener 22 is fixed to a fixed component such as a frame. In the first state, the fitting member 23 is separated from the fastener 22, and the support member 21 is movable; in the second state, the fitting member 23 is in contact with the fastener 22, and the support member 21 is fixed.

[0042] When the spacing between the clamping assemblies 1 needs to be changed, the first state is reached, i.e., the fitting member 23 and the fastener 22 are not engaged, and the movable support member 21 drives the clamping assemblies 1 to move along the length direction of the fastener 22. When the clamping assemblies 1 are in position, the second state is reached, where the fitting member 23 and the fastener 22 abut against each other, thereby abutting against the fixed support member 21. This allows the spacing between different groups of clamping assemblies 1 to be changed, thereby adapting to different products.

[0043] In some embodiments, the mating member 23 is a first air cylinder, and the fastener 22 is a fixed rod. In this embodiment, the fixed rod is cylindrical. The output end of the first air cylinder is connected to a first abutment block 24 by a screw connection. The first abutment block 24 is provided with a first abutment groove 25. The groove wall of the first abutment groove 25 is an arc-shaped structure that is consistent with the curvature of the outer wall of the fixed rod. When it is necessary to fix the support member 21, the first air cylinder drives the first abutment block 24 to move toward the fixed rod until the groove wall of the first abutment groove 25 abuts against the fixed rod, so that the support member 21 can be fixed, thereby fixing the position of the clamping assembly 1.

[0044] The implementation principle of a clamping mechanism in an embodiment of the present application is: the distance between the clamping components 1 is changed by adjusting the component 2, that is, the distance between different groups of clamping parts 11 is changed, and the support member 21 is moved to adjust the distance between the clamping components 1 to the size position of the corresponding product. When adjusted to the right position, the support member 21 is fixed by the fastener 22 and the mating member 23, that is, the spacing of the clamping components 1 is fixed, and the fixing member 12 changes the distance between the clamping parts 11 in the same group, so that the distance between the clamping parts 11 can be adjusted according to the required product size, so that it can adapt to products of different sizes.

[0045] The present application also discloses a punching device. Figure 6 The punching device includes the clamping mechanism described above, so that the punching device can punch products of different sizes.

[0046] In some embodiments, the punching device also includes a loading mechanism 7, a unloading mechanism 8, a punching mechanism 9 and a first driving mechanism 10. The loading mechanism 7 transmits the product to the clamping mechanism, and the first driving mechanism 10 drives the clamping mechanism to enter the punching mechanism 9. After the punching is completed, the first driving mechanism 10 drives the clamping mechanism to leave the punching mechanism 9, and the unloading mechanism 8 transmits the product to the unloading place.

[0047] Reference Figure 7 , the feeding mechanism 7 of this embodiment includes a feeding seat 71, a suction cup seat 72, a suction cup 73, a feeding motor 74, a feeding screw, a mounting seat 75, a moving motor 76 and a moving screw. The feeding seat 71 is used to place products, and the suction cup 73 is used to adsorb products. The suction cup 73 is mounted on the suction cup seat 72, and the suction cup seat 72 is screwed to the feeding screw. The feeding motor 74 drives the feeding screw to rotate and drives the suction cup seat 72 to approach or move away from the feeding seat 71. When the product needs to be adsorbed, the suction cup seat 72 is moved close to the feeding seat 71 to adsorb the product; the suction cup seat 72, the feeding motor 74 and the feeding screw are all mounted on the mounting seat 75, and the mounting seat 75 is screwed to the moving screw. The moving motor 76 drives the moving screw to rotate and drives the mounting seat 75 to approach the clamping assembly 1. After the clamping assembly 1 pushes out the clamped product, the mounting seat 75 returns to the loading position.

[0048] Reference Figure 8 In this embodiment, the first drive mechanism 10 includes a gantry 101, a movable plate 102, a first motor 103, and a first screw. The clamping mechanism is mounted on the movable plate 102, which is in turn mounted on the gantry 101. The first screw is threadedly connected to both sides of the gantry 101. The first motor 103 drives the first screw to rotate, moving the gantry 101, thereby moving the clamping mechanism closer to or further away from the punching mechanism 9. The direction of movement of the first drive mechanism 10 is perpendicular to the direction of movement of the loading mechanism 7 driven by the movable motor 76. The structure of the unloading assembly is identical to that of the loading assembly.

[0049] In some embodiments, the punching device also includes a visual positioning member 13 and a second driving member 14 and a third driving member 15. The visual positioning member 13 is a CCD camera device. The visual positioning member 13 is controlled and connected with the second driving member 14, the third driving member 15 and the fourth driving member. The visual positioning member 13 is used to locate the product position. The second driving member 14 drives the clamping mechanism to approach or move away from the punching mechanism 9 in the vertical direction. The third driving member 15 drives the clamping mechanism to move in the horizontal direction toward or away from the side of the feeding mechanism 7.

[0050] In this embodiment, the second driving member 14 includes a second motor 141, a second screw rod 142 and a connecting seat 143. The second screw rod 142 is screwed to the movable plate 102. The second motor 141 is fixed to the connecting seat 143. The second motor 141 drives the second screw rod 142 to rotate. The second screw rod 142 drives the movable plate 102, thereby driving the clamping mechanism to move along the second screw rod 142, that is, to move along the vertical direction.

[0051] Reference Figure 9 The third drive member 15 includes a third motor 151 and a third screw. The third motor 151 is fixed to the gantry 101. The third screw is screwed to the connecting seat 143. The third motor 151 drives the third screw to rotate. The connecting seat 143 moves along the third screw to drive the second motor 141, and the movable plate 102 drives the clamping mechanism to move. That is, it can drive the clamping mechanism to move left and right, even if the product is close to the side of the loading mechanism 7 or the side of the unloading mechanism 8. The visual positioning member 13 locates the position of the product, and then adjusts the position of the clamping mechanism by controlling the movement of the second drive member 14 and the third drive member 15. That is, after adjusting the position of the product, the first drive mechanism 10 moves the clamping mechanism to the punching mechanism 9 for punching, so that the punching position of the product can be more accurate.

[0052] The implementation principle of a punching device in an embodiment of the present application is: the punching device can adapt to products of different sizes by setting a clamping mechanism.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
