Description

Technical Field

[0001] This utility model relates to the field of packaging bag conveying technology, and more specifically, to a clamping device. Background Technology

[0002] After product packaging, the product needs to be transferred to the next process, which is usually done by clamping and releasing devices. The clamping and releasing of the product has a significant impact on its production quality and efficiency.

[0003] In existing technologies, robotic arms are commonly used to grip products. However, when releasing products, robotic arms are prone to snagging, which can lead to product stacking, affecting product transfer, and can also cause the product surface to come into contact with and rub against the robotic arm, posing a risk of damage to the product surface. Utility Model Content

[0004] The present invention aims to solve the above-mentioned defects by providing a clamping device that can effectively reduce product snagging and improve the efficiency and quality of products during transportation.

[0005] To solve the above problems, this utility model provides a clamping device, comprising:

[0006] A clamping member, the clamping member comprising a first jaw and a second jaw that are movable relative to or opposite to each other along a first direction;

[0007] A baffle, comprising a first baffle and a second baffle, wherein the first baffle is connected to the first gripper, the second baffle is connected to the second gripper, and a limiting space is formed between the first baffle and the second baffle;

[0008] When the first gripper and the second gripper move relative to each other in the first direction, the first baffle and the second baffle move in opposite directions in the first direction. When the first gripper and the second gripper move in opposite directions in the first direction, the first baffle and the second baffle move relative to each other in the first direction.

[0009] Furthermore, the first baffle includes a first fixing part, a first connecting part, and a first effective part. The first connecting part connects the first fixing part and the first effective part. The first connecting part extends along the first direction. The first fixing part is located at the upper end of the first connecting part. The first fixing part extends along the second direction. The first effective part is located at the lower end of the first connecting part. The first effective part extends along the second direction, which is perpendicular to the first direction.

[0010] Furthermore, the second baffle includes a second fixing part, a second connecting part, and a second effective part. The second connecting part connects the second fixing part and the second effective part. The second connecting part extends along the first direction. The second fixing part is located at the upper end of the second connecting part and extends along the second direction. The second effective part is located at the lower end of the second connecting part and extends along the second direction.

[0011] Furthermore, the first effective part is close to the inner wall of the second gripper, and the second effective part is close to the inner wall of the first gripper.

[0012] Furthermore, along the second direction, a preset distance is spaced between the first connecting portion and the second connecting portion.

[0013] Furthermore, the preset spacing is 1mm to 2mm.

[0014] Furthermore, the first fixing part is provided with a first through hole, and the first fixing part is connected to the first gripper through the first through hole;

[0015] The second fixing part is provided with a second through hole, and the second fixing part is connected to the second gripper through the second through hole.

[0016] Furthermore, the first fixing part, the first connecting part, and the first effective part are integrally connected and formed;

[0017] The second fixing part, the second connecting part, and the second effective part are integrally connected and formed.

[0018] Furthermore, an accommodating space is formed between the first gripper and the second gripper, and the first effective part and the second effective part are accommodated in the accommodating space;

[0019] The first gripper includes a first clamping end and a first fixing end, and the second gripper includes a second clamping end and a second fixing end. The first clamping end and the second clamping end are arranged opposite to each other along the first direction, and both the first clamping end and the second clamping end are provided with grooves.

[0020] Furthermore, the first gripper includes a first clamping end and a first fixing end, and the second gripper includes a second clamping end and a second fixing end. The first clamping end and the second clamping end are arranged opposite to each other along the first direction, and both the first clamping end and the second clamping end are provided with grooves.

[0021] The clamping device of this utility model connects a first baffle to the first jaw and a second baffle to the second jaw. When the first and second jaws move relative to each other to grip the product, the first and second baffles move away from each other, increasing the limiting space between the two baffles and preventing interference with the gripping of the product. When the first and second jaws move away from each other to release the product, the first and second baffles move relative to each other, decreasing the limiting space between the two baffles. This limiting space can constrain the upper part of the product, allowing it to fall stably from the limiting space, reducing the probability of the product contacting the jaws during the fall, thereby reducing the product snagging rate and minimizing frictional damage to the product surface. Using the clamping device provided by this utility model, precise product release can be achieved, with a snagging rate of no more than 0.1%, a product surface damage rate reduced by 80%, and product stacking avoided. This improves the efficiency and quality of product transfer, and the surface damage of the product can effectively distinguish between qualified and unqualified products, preventing unqualified products from entering the market.

[0029] The technical solution of this utility model will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In addition, in the description of this utility model, "at least one" means one or more, and "multiple" means two or more, unless otherwise explicitly specified.

[0030] In this specification, the term "as an alternative embodiment" means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one alternative embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same implementation or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] Combination Figures 1 to 4 As shown, this embodiment provides a clamping device, including: a clamping member and a baffle, wherein:

[0032] The clamping member includes a first jaw 11 and a second jaw 12, and there is an accommodating space between the first jaw 11 and the second jaw 12;

[0033] The baffle includes a first baffle 21 and a second baffle 22. The first baffle 21 is connected to the first gripper 11, and the second baffle 22 is connected to the second gripper 12. Both the first baffle 21 and the second baffle 22 are located within the accommodating space, and a limiting space is formed between the first baffle 21 and the second baffle 22. The first gripper 11 and the second gripper 12 are positioned along a first horizontal direction (i.e., the first direction). Figure 3 When the first gripper 11 and the second gripper 12 move relative to each other in the x-axis direction, the first baffle 21 and the second baffle 22 move in opposite directions in the first horizontal direction, making the limiting space larger; when the first gripper 11 and the second gripper 12 move in opposite directions in the first horizontal direction, the first baffle 21 and the second baffle 22 move relative to each other in the first horizontal direction, making the limiting space smaller.

[0034] The clamping device provided in this embodiment connects a first baffle to the first jaw and a second baffle to the second jaw. When the first and second jaws move relative to each other to grip the product, the first and second baffles move away from each other, increasing the limiting space between the two baffles and preventing interference with the gripping of the product. When the first and second jaws move away from each other to release the product, the first and second baffles move relative to each other, decreasing the limiting space between the two baffles. This limiting space can constrain the upper part of the product, allowing it to fall stably from the limiting space, reducing the probability of the product contacting the jaws during the fall, thereby reducing the product snagging rate and minimizing frictional damage to the product surface. Using the clamping device provided in this embodiment, precise product release can be achieved, with a snagging rate of no more than 0.1%, a product surface damage rate reduced by 80%, and product stacking avoided. This improves the efficiency and quality of product transfer, and the surface damage of the product can effectively distinguish between qualified and unqualified products, preventing unqualified products from entering the market.

[0035] In this embodiment, the upper part of product 1 refers to the area above the clamping portions of the first gripper 11 and the second gripper 12, that is... Figure 1 In area C of the existing robotic arm, when releasing product 1, inaccurate guidance and positioning of the gripper, or continuous gripping and releasing of product 1 causing the gripper to be in a moving state, leads to the upper part of product 1 easily contacting the gripper due to inertia or irregular shapes of the gripping part and upper part of product 1, resulting in snagging. The gripping device provided in this embodiment can reduce the probability of the upper part of the product contacting the gripper. This gripping device is suitable for products with regular shapes, and is even more suitable for products with irregular shapes of the gripping part and upper part of the product.

[0036] Based on the above embodiments, as an optional implementation method, combined with Figure 5 and Figure 7 As shown, the first baffle 21 includes a first fixing part 211, a first connecting part 212, and a first effective part 213. The first connecting part 212 connects the first fixing part 211 and the first effective part 213. The first connecting part 212 extends along a first horizontal direction. The first fixing part 211 is located at the upper end of the first connecting part 212, and the first fixing part 211 extends along a second horizontal direction (i.e., the second direction). Figure 3The first baffle 21 extends inward along the y-axis direction, and the first fixing part 211 is connected to the first gripper 11. The first effective part 213 is located at the lower end of the first connecting part 212, and the first effective part 213 extends inward along the second horizontal direction, so that the first effective part 213 is located in the accommodating space. When the first gripper 11 moves along the first horizontal direction, the first effective part 213 can approach or move away from the inner wall of the second gripper 12. Thus, the first baffle 21 adopts this structure, which can both limit the upper part of the product when releasing the product and reduce the spatial volume of the first baffle 21 without affecting the movement of other components.

[0037] It is understandable that "inward along the second horizontal direction" refers to the direction of the arrow along the y-axis, while "outward" refers to the direction away from the arrow along the y-axis.

[0038] Based on the above embodiments, as an optional implementation, the first fixing part 211 is provided with at least one first through hole 211a, through which fasteners such as screws or bolts can pass, locking the first fixing part 211 onto the first gripper 11, thus achieving the connection between the first fixing part 211 and the first gripper 11. Therefore, by locking the first baffle 21 onto the first gripper 11 through the first fixing part 211, when the driving member drives the first gripper 11 to move, the first baffle 21 can move synchronously with the first gripper 11, eliminating the need for an additional driving member to control the first baffle 21 and saving on continuously generated power source costs.

[0039] Based on the above embodiments, as an optional implementation, the first fixing part 211, the first connecting part 212, and the first effective part 213 are integrally connected and formed. Therefore, the integrally formed first baffle 21 has higher structural strength and lower processing cost. As an optional implementation, the first baffle 21 can be made by bending or stamping a metal or stainless steel plate.

[0040] Based on the above embodiments, as an optional implementation method, combined with Figure 5 and Figure 7As shown, the second baffle 22 includes a second fixing part 221, a second connecting part 222, and a second effective part 223. The second connecting part 222 connects the second fixing part 221 and the second effective part 223, and extends along a first horizontal direction. The second fixing part 221 is located at the upper end of the second connecting part 222 and extends inward along a second horizontal direction, connecting with the second gripper 12. The second effective part 223 is located at the lower end of the second connecting part 222 and extends inward along a second horizontal direction, placing the second effective part 223 within the accommodating space. When the second gripper 12 moves along the first horizontal direction, the second effective part 223 can approach or move away from the inner wall of the first gripper 11. Therefore, this structure of the second baffle 22 not only limits the upper part of the product when releasing it but also reduces the spatial volume of the second baffle 22 without affecting the movement of other components.

[0041] In this embodiment, the second effective part 223 and the first effective part 213 are disposed opposite to each other, and the second effective part 223 and the first effective part 213 can move relative to each other or move away from each other along the first horizontal direction. Specifically, when the first gripper 11 and the second gripper 12 move relative to each other along the first horizontal direction, the first effective part 213 and the second effective part 223 move away from each other along the first horizontal direction, and the first effective part 213 is close to the inner wall of the second gripper 12, while the second effective part 223 is close to the inner wall of the first gripper 11; when the first gripper 11 and the second gripper 12 move away from each other along the first horizontal direction, the first effective part 213 and the second effective part 223 move relative to each other along the first horizontal direction, and the first effective part 213 is away from the inner wall of the second gripper 12, while the second effective part 223 is away from the inner wall of the first gripper 11. Therefore, the size of the limiting space formed by the first effective part 213 and the second effective part 223 can be adjusted, thereby avoiding affecting the gripper's gripping of the product, and constraining the upper part of the product so that the upper part of the product can fall stably from the area defined by the limiting space, reducing the probability of the upper part of the product contacting the gripper.

[0042] Understandably, the minimum limiting space formed by the first effective part 213 and the second effective part 223 allows the upper part of the product to pass through, ensuring that the upper part of the product can fall smoothly from the limiting space.

[0043] Based on the above embodiments, as an optional implementation, the second fixing part 221 is provided with at least one second through hole 221a, through which fasteners such as screws or bolts can pass, locking the second fixing part 221 onto the second gripper 12, thus achieving the connection between the second fixing part 221 and the second gripper 12. Therefore, by locking the second baffle 22 onto the second gripper 12 through the second fixing part 221, when the driving member drives the second gripper 12 to move, the second baffle 22 can move synchronously with the second gripper 12, eliminating the need for an additional driving member to control the second baffle 22 and saving on continuously generated power source costs.

[0044] Based on the above embodiments, as an optional implementation, the second fixing part 221, the second connecting part 222, and the second effective part 223 are integrally connected and formed. Therefore, the integrally formed second baffle 22 has higher structural strength and lower processing cost. As an optional implementation, the second baffle 22 can be formed by bending or stamping metal or stainless steel plates.

[0045] Based on the above embodiments, as an optional implementation method, combined with Figure 6 As shown, along the second horizontal direction, the first connecting portion 212 and the second connecting portion 222 are spaced apart by a predetermined distance h. That is, the first connecting portion 212 is in front of the second connecting portion 222, and the first connecting portion 212 and the second connecting portion 222 are spaced apart by a predetermined distance. Thus, the predetermined distance between the first connecting portion 212 and the second connecting portion 222 allows the first baffle 21 and the second baffle 22 to perform interference-free misalignment movement, avoiding mutual interference or friction between the first baffle 21 and the second baffle 22, which could damage the upper part of the product.

[0046] It is understandable that the positions of the first connecting part 212 and the second connecting part 222 can also be interchanged, that is, the second connecting part 222 can also be located in front of the first connecting part 212, as long as a preset distance is ensured between the two connecting parts.

[0047] Based on the above embodiments, as an optional implementation, the preset spacing h is 1mm to 2mm. Therefore, with the preset spacing within this range, on the one hand, the first baffle 21 and the second baffle 22 can perform interference-free misalignment movement; on the other hand, the upper part of the product is confined to the area between the first connecting part 212 and the second connecting part 222. This helps improve the stability of the product when the grippers are holding it, and reduces or avoids the upper part of the product shifting during movement.

[0048] Based on the above embodiments, as an optional implementation manner, the first jaw 11 includes a first clamping end 111 and a first fixed end 112. The first fixed end 112 is connected to the first fixing portion 211, and the first clamping end 111 is located at the end of the first jaw 11 extending along the first horizontal direction; the second jaw 12 includes a second clamping end 121 and a second fixed end 122. The second fixed end 122 is connected to the second fixing portion 221, and the second clamping end 121 is located at the end of the second clamping portion 12 extending along the first horizontal direction. The first clamping end 111 and the second clamping end 121 are arranged opposite to each other, and there is a space for the product to pass through between the first clamping end 111 and the second clamping end 121. Grooves are provided on both the first clamping end 111 and the second clamping end 121. The groove can be arc-shaped to facilitate clamping the product. Of course, the groove can also be of other shapes, as long as the shape formed by enclosing the two grooves matches the shape of the clamping part of the product to ensure that the product can be clamped smoothly. The first jaw 11 and the second jaw 12 enclose a "convex" shape, and an accommodating space is formed between the first jaw 11 and the second jaw 12, so that the first effective portion 213 and the second effective portion 223 can move within this accommodating space.

[0049] It can be understood that when the first jaw 11 and the second jaw 12 move away from each other to release the product, along the first horizontal direction, the smaller the distance between the inner wall of the first effective portion 213 and the second clamping end 121 is, the better. However, the distance between the inner wall of the first effective portion 213 and the second clamping end 121 needs to be greater than 0, that is, the edges of the inner wall of the first effective portion 213 and the second clamping end 121 are not flush. Those skilled in the art can also set the distance between the inner wall of the first effective portion 213 and the second clamping end 121 along the first horizontal direction according to the actual situation. For example, the distance between the inner wall of the first effective portion 213 and the second clamping end 121 along the first horizontal direction is 2 mm. At the same time, along the first horizontal direction, the smaller the distance between the inner wall of the second effective portion 223 and the first clamping end 111 is, the better. However, the distance between the inner wall of the second effective portion 223 and the first clamping end 111 needs to be greater than 0, that is, the edges of the inner wall of the second effective portion 223 and the first clamping end 111 are not flush. Those skilled in the art can also set the distance between the inner wall of the second effective portion 223 and the first clamping end 111 along the first horizontal direction according to the actual situation. For example, the distance between the inner wall of the second effective portion 223 and the first clamping end 111 along the first horizontal direction is 2 mm. And, to ensure that the upper part of the product can pass through smoothly, it is necessary to ensure that the distance between the inner walls of the first effective portion 213 and the second effective portion 223 is greater than the diameter of the upper part of the product.

[0050] Based on the above embodiments, as an optional implementation, it further includes a pneumatic gripper frame 30. The first gripper 11 and the first baffle 21 are locked to the pneumatic gripper frame 30 by fasteners such as bolts or screws. The second gripper 12 and the second baffle 22 are also locked to the pneumatic gripper frame 30 by fasteners such as bolts or screws. Specifically, at least one third through hole is provided on the first fixed end 112. Fasteners such as bolts or screws pass through the first through hole 211a and the third through hole in sequence to lock the first gripper 11 and the first baffle 21 to the pneumatic gripper frame 30. At least one fourth through hole is provided on the second fixed end 122. Fasteners such as bolts or screws pass through the second through hole 221a and the fourth through hole in sequence to lock the second gripper 12 and the second baffle 22 to the pneumatic gripper frame 30. Thus, this arrangement can achieve reverse movement of the baffle and gripper to reduce the probability of contact between the upper part of the product and the gripper, without requiring modification of the original equipment, reducing the production cost of the gripping device, and improving the applicability of the gripping device.

[0051] Based on the above embodiments, as an optional implementation, a driving component is further included. This driving component is connected to the first gripper 11 via a pneumatic gripper frame 30, or to the second gripper 12 via the pneumatic gripper frame 30. It is used to drive the first gripper 11 and the second gripper 12 to clamp or release the product. When the driving component drives the first gripper 11 and the second gripper 12 to clamp or release the product, the first baffle 21 and the second baffle 22 also move synchronously. This eliminates the need for an additional driving component to separately drive the movement of the first baffle 21 and the second baffle 22, saving on continuously generated power source costs and further reducing the production cost of the clamping device. As an optional implementation, the driving component can be a cylinder or a motor.

[0052] The following combination Figures 1 to 7 The working principle of the clamping device provided in this embodiment will be explained as follows:

[0053] When the driving member drives the first gripper 11 and the second gripper 12 to clamp the product 1, the first gripper 11 and the second gripper 12 move relative to each other in the first horizontal direction. At this time, the first effective part 213 and the second effective part 223 move away from each other in the first horizontal direction. The upper part of the product 1 is located in the area between the first effective part 213, the second effective part 223, the first connecting part 212 and the second connecting part 222. When the driving member drives the first gripper 11 and the second gripper 12 to release the product 1, the first gripper 11 and the second gripper 12 move away from each other in the first horizontal direction. At this time, the first effective part 213 and the second effective part 223 move relative to each other in the first horizontal direction, causing the area between the first effective part 213, the second effective part 223, the first connecting part 212 and the second connecting part 222 to shrink. The upper part of the product 1 is constrained in this area, so that the upper part of the product 1 can fall stably from this area.

[0054] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
