[0036] Although the present invention can be easily embodied as embodiments of different forms, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0037] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0038] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0039] See also Figure 1 The utility model provides a handling device, including a mechanical arm 1 and a clamp 2, wherein the mechanical arm 1 provides a clamping force for the clamp 2 to clamp materials.

[0040] Two mechanical arms 1 are arranged opposite to each other, and two clamps 2 are arranged opposite to each other, and the two clamps 2 are respectively connected to the two mechanical arms 1. Taking the sagger 9 with the battery cells as the clamped material as an example, the two mechanical arms 1 drive the two clamps 2 to move to the two sides of the sagger 9, and then drive the two clamps 2 to approach each other to clamp the sagger 9, so that the two clamps 2 can clamp the sagger 9, and the mechanical arms 1 drive the clamps 2 to move and transport the sagger 9. When the sagger 9 is transported to the right place, the two mechanical arms 1 drive the two clamps 2 to move away from each other to release the sagger 9, and complete a transport process.

[0041] See also Figures 1 to 6The clamp 2 includes a back plate 21 and a clamping plate 22 connected along the thickness direction. The width of the back plate 21 is greater than the width of the clamping plate 22. The clamping plate 22 is flexible. The side of the clamping plate 22 facing away from the back plate 21 is a contact surface. A baffle is protrudingly provided on the side of the back plate 21 facing the clamping plate 22. The baffle extends along the length direction and protrudes outward from the contact surface in the thickness direction. The baffle includes a first baffle 211 and a second baffle 212 respectively located on both sides of the clamping plate 22 in the width direction.

[0042] Through the above structural design, the back plate 21 can be used to connect to the robot arm 1 to provide clamping force. When the clamp 2 clamps the material, the contact surface of the clamp 22 contacts the material and places the material between the first baffle 211 and the second baffle 212. The flexibility of the clamp 22 allows the clamp 22 to deform to a certain extent, and the clamp 22 will not be in rigid contact with the material to cause damage. The first baffle 211 and the second baffle 212 are used to protrude the outside of the contact surface in the thickness direction. When the friction between the clamp 22 and the material is insufficient and causes the material to fall, the first baffle 211 or the second baffle 212 can be used to support the material to prevent the material from continuing to fall and causing collision damage. The first baffle 211 and the second baffle 212 can both support the material when the clamp 2 drives the material to flip.

[0043] It should be noted that a receiving groove for placing the battery cell is provided in the sagger 9, the bottom of the receiving groove has a bottom plate, and the top of the receiving groove has an opening. During the movement of the sagger 9, the opening of the receiving groove faces upward, and the first stop bar 211 can form a support under the bottom plate. When the sagger 9 is transported to the right place, the robot arm 1 drives the clamp 2 to drive the sagger 9 to flip, and the opening of the receiving groove faces downward to unload, and the second stop bar 212 can form a support under the opening edge of the receiving groove.

[0044] The contact surface is provided with an anti-skid structure. The anti-skid structure provides friction between the contact surface and the material, prevents the material from slipping, and improves the stability of the clamp 2. The anti-skid structure and the first stop bar 211 and the second stop bar 212 form a secondary anti-skid effect.

[0045] The anti-skid structure includes a plurality of anti-skid strips 221 protruding from the contact surface. The friction between the contact surface and the material is increased by the plurality of anti-skid strips 221. The anti-skid strips 221 extend in the length direction, and the plurality of anti-skid strips 221 are arranged in parallel and spaced apart in the width direction. In other embodiments, the contact surface may also be provided with a plurality of honeycomb-shaped grooves to form an anti-skid structure. Of course, the anti-skid structure may also be other structures that can increase the friction between the contact surface and the material.

[0046] In this embodiment, the back plate 21 and the clamping plate 22 are both rectangular plate-shaped structures, and the thickness direction, the width direction and the length direction are three directions that are perpendicular to each other.

[0047] An anti-slip structure is provided between the back plate 21 and the clamping plate 22, and the anti-slip structure increases the resistance of the clamping plate 22 to slide relative to the back plate 21 along the length direction. It is understandable that when the connection strength between the back plate 21 and the clamping plate 22 fails, the clamping plate 22 will slide relative to the back plate 21. When the clamping plate 22 slides relative to the back plate 21 along the width direction, it will also cause the material to fall, but the first baffle 211 and the second baffle 212 located on both sides of the width direction of the clamping plate 22 are also used to support the falling material to prevent the material from falling. When the clamping plate 22 slides relative to the back plate 21 along the length direction and causes the material to fall (during the flipping process), since there are no baffles on both sides of the length direction of the clamping plate 22, the material will fall and be damaged. Therefore, an anti-slip structure that can increase the resistance of the clamping plate 22 to slide relative to the back plate 21 along the length direction is provided to prevent the clamping plate 22 from sliding relative to the back plate 21 along the length direction, thereby improving the clamping stability during the flipping process of the clamp 2.

[0048] The anti-slip structure includes an anti-slip strip 222 extending in the length direction and an anti-slip groove 213 extending in the length direction. One of the anti-slip strip 222 and the anti-slip groove 213 is arranged on the side of the back plate 21 facing the clamping plate 22, and the other is arranged on the side of the clamping plate 22 facing the back plate 21, and the anti-slip strip 222 is adapted to be installed in the anti-slip groove 213. The anti-slip strip 222 and the anti-slip groove 213 increase the contact area between the back plate 21 and the clamping plate 22, and the anti-slip strip 222 and the anti-slip groove 213 are both along the length direction, thereby greatly improving the friction resistance between the back plate 21 and the clamping plate 22 in the length direction. Of course, in other embodiments, the anti-slip strip 222 and the anti-slip groove 213 can also extend in the width direction, or extend in a direction that is at any angle to the length direction / width direction.

[0049] In this embodiment, the anti-slip groove 213 is disposed on the side of the back plate 21 facing the clamping plate 22 , and the anti-slip strip 222 is disposed on the side of the clamping plate 22 facing the back plate 21 .

[0050] The plurality of anti-slip strips 222 include a first anti-slip strip 2221 and a second anti-slip strip 2222. In the thickness direction, the width from the top to the bottom of the first anti-slip strip 2221 is equal, and the width from the top to the bottom of the second anti-slip strip 2222 gradually decreases. The plurality of anti-slip grooves 213 include a first anti-slip groove 2131 and a second anti-slip groove 2132. In the thickness direction, the width from the top to the bottom of the first anti-slip groove 2131 is equal, and the width from the top to the bottom of the second anti-slip groove 2132 gradually increases. The first anti-slip strip 2221 is adapted to be installed in the first anti-slip groove 2131, and the second anti-slip strip 2222 is adapted to be installed in the second anti-slip groove 2132.

[0051] The first anti-slip strip 2221 and the first anti-slip groove 2131 serve to increase the resistance of the clamping plate 22 to sliding relative to the back plate 21 along the length direction. The second anti-slip strip 2222 and the second anti-slip groove 2132 not only serve to increase the resistance of the clamping plate 22 to sliding relative to the back plate 21 along the length direction, but also serve to limit the movement of the clamping plate 22 relative to the back plate 21 along the thickness direction, thereby preventing the clamping plate 22 and the back plate 21 from separating.

[0052] The first anti-slip groove 2131 and the second anti-slip groove 2132 are both through grooves with openings at both ends, the first anti-slip strip 2221 is inserted from the opening at one end of the first anti-slip strip 2221, and the second anti-slip strip 2222 is inserted from the opening at one end of the second anti-slip strip 2222, so that the clamping plate 22 moves in the length direction relative to the back to complete the connection between the clamping plate 22 and the back plate 21. Of course, in other embodiments, the back plate 21 and the clamping plate 22 can also be bonded by colloid or the like.

[0053] The dimension of the back plate 21 in the length direction is greater than the dimension of the back plate 21 in the width direction, and the dimension of the splint 22 in the length direction is greater than the dimension of the splint 22 in the width direction, so that the anti-slip strip 222 and the anti-slip groove 213 extending along the length direction can have a longer arrangement length, thereby increasing the resistance of the splint 22 to sliding relative to the back plate 21 along the length direction.

[0054] In this embodiment, there are two groups of first anti-slip bars 2221 and first anti-slip grooves 2131, and one group of second anti-slip bars 2222 and second anti-slip grooves 2132. The two groups of first anti-slip bars 2221 and first anti-slip grooves 2131 are respectively arranged on both sides of one group of second anti-slip bars 2222 and second anti-slip grooves 2132.

[0055] The back plate 21 and the clamping plate 22 are both made of non-metallic materials, which can avoid the introduction of magnetic objects in the battery production process. Considering the high temperature of the material when the sagger 9 is recycled, the clamping plate 22 can also be made of a high-temperature resistant non-metallic material to strengthen the heat resistance of the clamping plate 22 material, so that the clamping plate 22 is not easy to age and the service life of the clamping plate 22 is increased.

[0056] The back plate 21 is provided with a mounting hole 214 that passes through the back plate 21 in the thickness direction, and the mounting hole 214 is located between the first stop bar 211 and the second stop bar 212 in the width direction. The mounting hole 214 includes a first hole portion 2141 and a second hole portion 2142 that are connected to each other, the aperture of the first hole portion 2141 is larger than the aperture of the second hole portion 2142, and the first hole portion 2141 is farther away from the clamping plate 22 than the second hole portion 2142 in the thickness direction. The clamp 2 also includes a fastener 24, the fastener 24 includes a rod portion 241 and a head portion 242 connected to one end of the rod portion 241, the outer diameter of the head portion 242 is larger than the outer diameter of the rod portion 241, and the outer diameter of the head portion 242 is larger than the outer diameter of the first hole portion 2141. The rod portion 241 is inserted into the first hole portion 2141, and the head portion 242 is arranged in the second hole portion 2142.

[0057] When the fastener 24 is loose, the fastener 24 will slide out from one side of the head 242. When the splint 22 is connected to the back plate 21, the head 242 is hidden between the splint 22 and the back plate 21. The splint 22 can prevent the fastener 24 from sliding out from one side of the head 242, thereby preventing the fastener 24 from loosening and falling, causing quality failure and equipment failure.

[0058] It is worth mentioning that in the related art, the head 242 is exposed on the side of the back plate 21 facing away from the clamping plate 22. When the fastener 24 is loose, it will slide out and fall off by the side of the head 242. Especially during multiple flipping processes, there is a risk that the fastener 24 will fall into the equipment along with the material.

[0059] One end of the rod portion 241 away from the head portion 242 extends out of the first hole portion 2141 for connecting to the robot arm 1. In this embodiment, the fastener 24 may be a bolt.

[0060] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
