Description

Technical Field

[0001] This application relates to the technical field of clamping, and in particular to a clamping mechanism for stacked products. Background Technology

[0002] For sheet-shaped non-standard products, the products need to be clamped, conveyed, and transferred. In existing technologies, the products are usually moved from one process to another manually. This process is not only cumbersome but also increases labor costs and has low conveying efficiency.

[0003] Therefore, it is necessary to design a stacked product clamping mechanism to improve conveying efficiency by clamping and conveying batches of products. Utility Model Content

[0004] To facilitate the batch clamping and conveying of sheet products, this application provides a stacked product clamping mechanism.

[0005] This application provides a stacked product clamping mechanism, which adopts the following technical solution:

[0006] A stacked product clamping mechanism includes a pneumatic gripper, the pneumatic gripper including a pneumatic component and two jaws, each of the two jaws having a spring plate on the side away from each other, and each of the two spring plates having a clamping member located below the jaws on the side closer to each other.

[0007] By adopting the above technical solution, after placing several stacked sheet products, the bottom product is clamped by the gripper. During the clamping process, the spring sheet is deformed away from the gripper by force. The spring sheet applies elastic force to the clamping parts in the direction close to the product, so that the gripper is in full contact with the bottom product, ensuring the clamping force of the bottom product, thereby facilitating the batch clamping and conveying of sheet products.

[0008] Optionally, the two grippers are provided with a first rubber pad on one side close to each other.

[0009] By adopting the above technical solution, except for the bottom layer of products, the other products are wrapped on both sides by the first rubber pad, which improves the stability of clamping the stacked products.

[0010] Optionally, both sides of the two grippers are provided with limiting components. The limiting components include connecting rods and limiting rods. The limiting rods are fixedly installed on the connecting rods. A sliding rod is provided at the same end of both connecting rods. Sliding grooves that cooperate with the sliding rods are opened on both sides of one side of the gripper. The sliding rods are located in the sliding grooves and are slidably connected to the grippers. A connecting hole is opened at the end of the sliding rod. The connecting rod passes through the connecting hole and is slidably connected to the connecting rod. A moving rod is provided at the end of the connecting rod away from the sliding rod. A moving groove that cooperates with the moving rod is opened on the gripper on the side close to the moving rod. The moving rod is located in the moving groove and is slidably connected to the gripper. A moving component that drives the moving rod to move is provided inside the gripper.

[0011] By adopting the above technical solution, based on the width of the product, the moving rods on both sides are moved closer to each other by the moving component, so that the distance between the two limiting rods matches the width of the product. During the clamping process of the gripper holding the stacked products, the limiting rods are made to fit against the side wall of the product, thereby improving the stability of the product clamping and moving process.

[0012] Optionally, the moving assembly includes two screws with different directions and two moving blocks. The two screws with different directions are located inside the gripper and are rotatably connected to the gripper. The two moving blocks are threadedly connected to the two screws respectively, and the two moving blocks are fixedly connected to the two moving rods respectively.

[0013] By adopting the above technical solution, the moving rod is moved along the length of the screw by rotating the screw, thereby driving the connecting rod to move and adjusting the distance between the two connecting rods.

[0014] Optionally, the two screws are connected at one end close to each other by a worm gear, and a worm wheel is rotatably connected inside the gripper, the worm wheel meshing with the worm gear.

[0015] By adopting the above technical solution, the worm gear rotates, causing the worm to rotate, which in turn causes the two screws to rotate.

[0016] Optionally, a rotating shaft is coaxially fixedly connected to the worm gear, and a drive shaft is provided outside the gripper. The drive shaft is rotatably connected to the gripper, and the end of the drive shaft is connected to the rotating shaft through a bevel gear pair.

[0017] By adopting the above technical solution, the drive shaft is rotated, and the rotating shaft is driven to rotate by the bevel gear pair, thereby causing the worm gear to rotate.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] After placing several stacked sheet products, the bottom product is clamped by the gripper. During the clamping process, the spring sheet is deformed away from the gripper by the force. The spring sheet applies a spring force to the clamping parts in the direction close to the product, so that the gripper can fully contact the bottom product and ensure the clamping force of the bottom product, thus facilitating the batch clamping and conveying of sheet products.

[0020] Based on the width of the product, the moving rods on both sides are moved closer to each other by the moving component, so that the distance between the two limiting rods matches the width of the product. During the clamping process of the gripper holding the stacked products, the limiting rods are made to fit against the side wall of the product, improving the stability of the product clamping and moving process.

[0027] The present application will be further described in detail below with reference to all the accompanying drawings. Example

[0028] This application discloses a stacked product clamping mechanism.

[0029] Reference Figure 1A stacked product clamping mechanism includes a pneumatic gripper 1, which comprises a pneumatic assembly 11 and two grippers 12. Each gripper 12 has a spring plate 2 positioned on its opposite side, and a clamping member 3 positioned below each gripper 12 on its opposite side. The pneumatic assembly 11 is used to move the two grippers 12 closer together or further apart. The pneumatic assembly 11 is prior art and will not be described in detail here. After placing several stacked sheet-like products, the grippers 12 clamp the bottom layer of products. During clamping, the spring plates 2 deform away from the grippers 12, applying a spring force to the clamping members 3 towards the product, ensuring full contact between the grippers 12 and the bottom layer of products, thus facilitating the batch clamping and conveying of sheet-like products.

[0030] Reference Figure 1 Two grippers 12 are positioned close to each other on one side with a first rubber pad 4. Except for the bottom layer of products, the other products are wrapped on both sides by the first rubber pad 4, which improves the stability of clamping the stacked products.

[0031] The implementation principle of a stacked product clamping mechanism in this application embodiment is as follows: After placing several stacked sheet products, the bottom product is clamped by the gripper 12. During the clamping process, the spring plate 2 is deformed away from the gripper 12 by force. The spring plate 2 applies a spring force to the clamping member 3 in the direction close to the product, so that the gripper 12 is in full contact with the bottom product, ensuring the clamping force of the bottom product, thereby facilitating the batch clamping and conveying of sheet products. Example

[0032] Reference Figure 1 Both sides of the two grippers 12 are provided with limit components 5. The limit components 5 include connecting rods 51 and limit rods 52. The limit rods 52 are fixedly installed on the connecting rods 51. The two connecting rods 51 are provided with sliding rods 53 at the same end. The grippers 12 on one side are provided with sliding grooves 121 that cooperate with the sliding rods 53. The sliding rods 53 are located in the sliding grooves 121 and are slidably connected to the grippers 12. The end of the sliding rods 53 is provided with a connecting hole. The connecting rods 51 pass through the connecting hole and are slidably connected to the connecting rods 51. During the relative movement of the two grippers 12, the connecting rods 51 and the sliding rods 53 move relative to each other. The end of the connecting rods 51 away from the sliding rods 53 is provided with a moving rod 54. The grippers 12 on the side close to the moving rods 54 are provided with a moving groove 122 that cooperates with the moving rods 54. The moving rods 54 are located in the moving grooves 122 and are slidably connected to the grippers 12. The grippers 12 are provided with a moving component 6 that drives the moving rods 54 to move. Based on the width of the product, the moving rods 54 on both sides are moved closer to each other by the moving component 6, so that the distance between the two limiting rods 52 matches the width of the product. During the clamping process of the gripper 12 on the stacked products, the limiting rods 52 are made to fit against the side wall of the product, thereby improving the stability of the product during the clamping and moving process.

[0033] Reference Figure 1 The moving component 6 includes two screws 61 pointing in opposite directions and two moving blocks 62. The two screws 61 are located inside and rotatably connected to the gripper 12. The two moving blocks 62 are threadedly connected to the two screws 61 respectively, and are fixedly connected to the two moving rods 54 respectively. The two screws 61 are connected at one end close to each other via a worm gear 63. A worm wheel 64 is rotatably connected inside the gripper 12, and the worm wheel 64 meshes with the worm gear 63. A rotating shaft 66 is coaxially fixedly connected to the worm wheel 64. A drive shaft 67 passes through the gripper 12 and is rotatably connected to the gripper 12. The end of the drive shaft 67 is connected to the rotating shaft 66 via a bevel gear pair 65.

[0034] By rotating the drive shaft 67, the rotating shaft 66 is driven to rotate through the bevel gear pair 65, thereby causing the worm gear 64 to rotate. By rotating the worm gear 64, the worm 63 rotates, thereby causing the two screws 61 to rotate. This causes the moving rod 54 to move along the length of the screw 61, thereby driving the connecting rod 51 to move and adjusting the distance between the two connecting rods 51.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
