Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a stacking handling clamp. Background Art

[0002] Battery boxes are mostly formed by extruding sheet materials. Therefore, when preparing the sheet materials, a punching machine is mostly used to punch multiple sheets of materials at one time to form stacked sheet materials, and then a conveying device is used to transport the stacks of materials to the next work station.

[0003] During the handling of stacked sheet materials, it is necessary to ensure that the stacks are aligned and regular, and the alignment of the stacks must not be destroyed. In the prior art, a mechanical gripper is often used to grab the stacks when handling the stacks. However, when the mechanical gripper clamps the stacks, the clamping force applied by the mechanical gripper to the stacks is rigid. If the stacks need to be clamped, the stacks need to be completely pressed. However, if the force is too large, the mechanical gripper will exert too much force on the stacks, destroying the flatness of the stack surface. If the force is too small, the stacks cannot be gripped, and the stacks may fall apart during the gripping process.

[0004] Therefore, there is room for further improvement in the prior art for grabbing equipment for laminated materials. Utility Model Content

[0005] In view of this, in order to solve the technical problem that the gripping equipment in the above-mentioned prior art provides a rigid clamping force for the stack, which may be too large to damage the surface flatness of the stack, or too small to grasp the stack, the present application provides a stack handling clamp, which is provided with an elastic mechanism, which cooperates with the clamping hand to provide an elastic buffering force, so that the clamp can better clamp the stack.

[0042] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0043] In the description of this application, if there is a description of first or second, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0044] Those skilled in the art should understand that, in the disclosure of the present application, the orientation or positional relationship indicated by terms such as "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", and "outside" are based on the orientation or positional relationship shown in the accompanying drawings, which are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present application.

[0045] The present application is further described in detail below in conjunction with the accompanying drawings. Figures 1 to 6 illustrate.

[0046] The present application provides a stacking handling fixture (hereinafter referred to as the handling fixture), such as Figures 1 to 3 As shown, the transport clamp 1 is used to transport sheet-like stacked materials, and includes a mounting support 2, a clamping mechanism 3 and a driving mechanism 4. The driving mechanism 4 is connected to the mounting support 2, and the driving mechanism 4 is connected to the clamping mechanism 3 to control the clamping mechanism 3 to open or close, thereby clamping the stack; and, the present application provides an elastic member 7 in the clamping mechanism 3. When the clamping mechanism 3 applies a force to the stack, the stack applies a reaction force to the clamping mechanism 3, and the reaction force pushes the clamping mechanism 3 to move in the opposite direction. With the cooperation of the elastic member 7, the elastic member 7 absorbs energy and reduces shock, so that the clamping mechanism 3 can move slightly in the opposite direction, thereby alleviating the rigid force applied by the clamping mechanism 3 itself to the stack, thereby ensuring that the clamping mechanism 3 can clamp the stack while also ensuring that the clamping mechanism 3 will not squeeze the stack due to excessive force, thereby avoiding damage to the surface flatness of the stack.

[0047] Specifically, Figure 1 to Figure 2 As shown, the clamping mechanism 3 includes two clamping parts, namely a first clamping part 5 and a second clamping part 6. The first clamping part and the second clamping part 6 are arranged at intervals, and the first clamping part 5 is located above the second clamping part 6. In this embodiment, as shown in FIG. Figures 1 to 3As shown, the driving mechanism 4 is connected to the first clamping part 5 and is used to control the first clamping part 5 to move toward or away from the second clamping part 6, thereby changing the spacing between the clamping parts, thereby achieving clamping of the laminate.

[0048] It should be noted that in the present application, the driving mechanism 4 can be connected to the first clamping part alone and drive the second clamping part 6 to move alone; it can also be connected to the second clamping part 6 alone and drive the second clamping part 6 to move alone; or it can be connected to the first clamping part 5 and the second clamping part 6 at the same time, and drive the first clamping part 5 and the second clamping part 6 to move in the opposite or opposite directions, so as to achieve the clamping of the laminate; any of the above connection schemes can achieve the clamping of the laminate by the clamping mechanism 3. In actual use, different schemes can be selected according to needs. In the present application, the driving mechanism 4 is preferably connected to the first clamping part 5.

[0049] Among them, Figure 2 , Figure 3As shown, the first clamping part 5 includes a clamping plate 13, a fixing member 14 and a limiting member 15, the clamping plate 13 is a rectangular plate-like structure, the fixing member 14 is an L-shaped plate-like structure, and the limiting member 15 is a plate-like structure or a block-like structure; the fixing member 14 is located between the limiting member 15 and the clamping plate 13, the limiting member 15 is located above the fixing member 14, and the clamping plate 13 is located below the fixing member 14, that is, the limiting member 15, the fixing member 14 and the clamping plate 13 are arranged in sequence; the fixing member 14 includes a long plate and a short plate, the long plate is connected to the short plate, the angle of connection between the long plate and the short plate is 90 degrees, the long plate is located between the limiting member 15 and the clamping plate 13, and the short plate rotates with the driving mechanism 4 The splint 13 is used to contact the laminate, and a connecting column 16 is provided on the splint 13. The connecting column 16 is fixedly connected to the splint 13. The connecting column 16 is a circular columnar structure, and the length extension direction of the connecting column 16 is parallel to the moving direction of the first clamping portion 5. The fixing member 14 is provided with a sliding hole 17 for the connecting column 16 to pass through. The inner diameter of the sliding hole 17 is larger than the outer diameter of the connecting column 16. The connecting column 16 is slidably connected to the fixing member 14. The connecting column 16 passes through the fixing member 14 and is fixedly connected to the limiting member 15. The limiting member 15 is used to limit the connecting column 16. The elastic member 7 is sleeved on the connecting column 16, and the elastic member 7 is located on the fixing member 14. and the clamping plate 13; therefore, the driving mechanism 4 drives the fixing member 14 to move, and when the first clamping part 5 does not apply a force to the laminate, the clamping plate 13, the limiting member 15 and the fixing member 14 move synchronously, and when the first clamping part 5 applies a force to the laminate, the clamping plate 13 acts on the laminate, and the laminate applies a reaction force to the clamping plate 13. After receiving the reaction force, the clamping plate 13 moves in a direction away from the laminate, driving the connecting column 16 and the limiting member 15 to move, and the fixing member 14 remains stationary. Under the action of the elastic member 7, the movement of the clamping plate 13 is restricted, so that the clamping plate 13 can only move slightly within a reasonable range, and will not move excessively. The clamping mechanism 3 moves and releases the pressure on the laminate, so the clamping mechanism 3 still maintains the clamping of the laminate, but because the clamping plate 13 is displaced relative to the fixing member 14, the force actually applied by the clamping mechanism 3 to the laminate will not be too large. To a certain extent, the structure in which the elastic member 7 and the clamping plate 13 slide against the fixing member 14 first buffers the rigid force originally applied by the first clamping portion 5 to the laminate. Therefore, the clamping mechanism 3 of the present application can ensure that the laminate is clamped, and can ensure that the laminate will not be worn or squeezed due to excessive clamping force, thereby ensuring the flatness of the laminate surface and further improving the effect of clamping the laminate.

[0050] Further, such as Figure 3 , Figure 5As shown, a limiting sleeve 20 is provided on the fixing member 14, and a through hole 18 is provided in the limiting sleeve 20 for the connecting column 16 to pass through, and the axis of the sliding hole 17 and the through hole 18 are in the same straight line; the cross section of the limiting sleeve 20 is L-shaped, which includes a straight tube portion and an annular portion, the straight tube portion is partially located in the sliding hole 17, the through hole 18 is arranged on the straight tube portion, the inner diameter of the through hole 18 is smaller than the inner diameter of the sliding hole 17, the outer diameter of the straight tube portion is smaller than the inner diameter of the sliding hole 17, the annular portion is connected to the lower end of the straight tube portion, the outer diameter of the annular portion is larger than the outer diameter of the sliding hole 17, the side of the annular portion close to the fixing member 14 is in contact with the fixing member 14, and the annular portion is fixedly connected to the fixing member 14; and the elastic member 7 is a spring, and the spring acts on the annular portion of the limiting sleeve 20, so that the limiting sleeve 20 plays a limiting role on the elastic member 7, prevents the elastic member 7 from being misplaced and moved into the sliding hole 17, and ensures that the elastic member 7 can be compressed, thereby providing an elastic force to the clamping plate 13.

[0051] Further, such as Figure 5 As shown, a guide cylinder 21 is provided between the fixing member 14 and the limiting member 15, and the guide cylinder 21 includes a straight cylinder portion and an annular portion, the annular portion is connected to the middle position of the straight cylinder portion, and a guide hole is provided on the straight cylinder portion for the connecting column 16 to pass through, and the inner diameter of the guide hole is roughly the same as the outer diameter of the connecting column 16, and the outer wall of the connecting column 16 fits with the inner wall of the straight cylinder portion; the lower part of the straight cylinder portion is located in the sliding hole 17, and the outer diameter of the straight cylinder portion is roughly the same as the inner diameter of the sliding hole 17, and the outer wall of the straight cylinder portion fits with the inner wall of the sliding hole 17, and the side of the annular portion close to the fixing member 14 fits with the fixing member 14, and the outer diameter of the annular portion is larger than the inner diameter of the sliding hole 17, and the annular portion is fixedly connected to the fixing member 14 by bolts, and the connecting column 16 is slidably connected to the guide cylinder 21, and the guide cylinder 21 has a guiding function for the connecting column 16, so as to prevent the connecting column 16 from being misaligned when sliding relative to the fixing member 14, thereby ensuring the stability of the movement of the clamp 13, thereby improving the clamping stability of the handling fixture 1 for the stack.

[0052] Further, if Figure 3 , Figure 4 As shown, a buffer pad 22 is provided on the side of the splint 13 away from the fixing part 14, that is, a buffer pad 22 is provided on the lower end surface of the splint 13, the buffer pad 22 is elastic, and the buffer pad 22 is made of rubber material. The area of ​​the buffer pad 22 is roughly the same as the area of ​​the splint 13, and the buffer pad 22 covers the lower end surface of the splint 13; the buffer pad 22 is provided with strip-shaped protrusions, and there are at least two strip-shaped protrusions, and the strip-shaped protrusions are arranged in parallel at intervals, so that the surface of the buffer pad 22 has a concave-convex structure, which can increase the friction between the buffer pad 22 and the laminate, clamp the laminate, and the buffer pad 22 directly acts on the laminate to prevent the splint 13 from acting on the laminate and scratching the laminate.

[0053] like Figure 3 , Figure 6As shown, the driving mechanism 4 includes a driving motor 8 and a screw 9, the mounting support 2 includes a mounting plate 19, the driving motor 8 is fixedly connected to one side of the mounting plate 19, and the screw 9 is connected to the other side of the mounting plate 19, wherein the screw 9 is arranged on the same side as the clamping mechanism 3; the length extension direction of the screw 9 is parallel to the moving direction of the clamping portion, one end of the screw 9 is connected to the driving motor 8, and the other end is rotatably connected to the mounting support 2, as shown in FIG. Figure 5 As shown, the lower end of the screw rod 9 is connected to the driving mechanism 4, and the upper end is connected to the mounting support 2, wherein the screw rod 9 is rotatably connected to the mounting support 2, the screw rod 9 can rotate in situ, and the clamping portion is threadedly connected to the threaded portion of the screw rod 9. When the driving motor 8 drives the screw rod 9 to rotate, the rotational force is converted into a linear displacement of the clamping portion, so that the clamping portion can move along the screw rod 9.

[0054] Further, such as Figure 6 As shown, the driving mechanism 4 also includes a driving wheel 10, a driven wheel 11 and a synchronous belt 12. The driving wheel 10 is fixedly connected to the rotating shaft of the driving motor 8, and the driven wheel 11 is connected to the end of the screw 9 close to the driving wheel 10, that is, the driven wheel 11 is connected to the lower end of the screw 9. The driving wheel 10 and the driven wheel 11 are connected by the synchronous belt 12, so that when the driving motor 8 is running, it can drive the screw 9 to rotate.

[0055] It should be noted that when the driving mechanism 4 drives the first clamping part 5 and the second clamping part 6 at the same time, two threaded parts can be set on the screw 9, and the thread rotation directions of the two threaded parts are different. The first clamping part 5 and the second clamping part 6 are respectively connected to the two screw parts 9. When the screw 9 rotates, the first clamping part 5 and the second clamping part 6 can be driven simultaneously. The first clamping part 5 and the second clamping part 6 can move toward or oppositely to achieve clamping of the stacked sheets.

[0056] like Figure 1 to Figure 2 , Figure 4 As shown, the mounting support 2 is provided with a guide rail 23, and there are two guide rails 23. The two guide rails 23 are symmetrically arranged on both sides of the screw 9, and the length extension direction of the guide rail 23 is parallel to the length extension direction of the screw 9; a slider 24 is provided on the first clamping part 5, one end of the slider 24 is fixedly connected to the short plate of the fixing member 14, and the other end is slidably connected to the guide rail 23, so that when the first clamping part 5 moves, the connection point between the first clamping part 5 and the mounting support 2 can be increased, and the slider 24 cooperates with the guide rail 23 to increase the movement stability of the first clamping part 5, thereby ensuring the clamping stability of the clamping mechanism 3.

[0057] It should be noted that, in the present application, the first clamping portion 5 and the second clamping portion 6 can be configured to have the same structure or different structures. In the present application, it is preferred that the second clamping portion 6 has a different structure from the first clamping portion 5, such as Figures 1 to 3As shown, the second clamping portion 6 includes a clamping block 25, which is a long strip structure. The length extension direction of the clamping block 25 is perpendicular to the length extension direction of the screw 9. Two clamping blocks 25 are provided, and the two clamping blocks 25 are arranged in parallel and spaced apart. The spacing between the two clamping blocks 25 is less than the length of the laminate, and the length of the clamping block 25 is greater than the width of the laminate, so as to ensure that the two clamping blocks 25 can act on the laminate at the same time, increase the supporting area of ​​the laminate, and improve the clamping stability of the clamping mechanism 3 on the laminate; as shown Figure 3 As shown, one end of the clamp block 25 is fixedly connected to the mounting bracket 2, and the free end of the clamp block 25 is a wedge-shaped structure, that is, the thickness of the free end of the clamp block 25 is relatively small, and the bottom surface of the free end is an inclined surface, which enables the second clamping portion 6 to be able to easily extend into the lower end of the stack to lift the stack.

[0058] Further, such as Figure 1 , Figure 3 As shown, an elastic pad 26 is provided on one side of the clamping block 25 facing the first clamping portion 5. The elastic pad 26 is made of rubber material and has elasticity, and can buffer the laminate to prevent the clamping block 25 from directly acting on the laminate and scratching the laminate.

[0059] It should be noted that the various embodiments of the present application can be arbitrarily combined into a new embodiment if the solutions do not conflict and the technical solutions can coexist.
