Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features. In some utility model descriptions, "plurality" means two or more, unless otherwise specifically specified.

[0040] The utility model provides a kind of clamping mechanism, for clamping workpiece, and in the process of transferring workpiece can avoid workpiece to fall off.In some embodiments, workpiece can be battery module.

[0041] In combination Figure 1 And Figure 2 A kind of clamping mechanism, including installation component 100, clamping component 200 and anti-falling component 300.Clamping component 200 and anti-falling component 300 are arranged on installation component 100, clamping component 200 is used to clamp workpiece, and anti-falling component 300 is used to support the bottom of workpiece clamped by clamping component 200.

[0042] Further, clamping component 200 can include first clamping piece 210 and second clamping piece 220, first clamping piece 210 and second clamping piece 220 are oppositely arranged on installation component 100 along the first direction, and first clamping piece 210 and second clamping piece 220 can be close to each other or away from each other to clamp or loosen workpiece.

[0043] Anti-falling component 300 includes support structure 310 and anti-falling driving structure 320, support structure 310 is rotationally connected to installation component 100, anti-falling driving structure 320 is drivingly connected with support structure 310, and support structure 310 can be driven to rotate relative to installation component 100 to the end of support structure away from installation component 100 is located at the bottom of workpiece, and workpiece is supported.

[0044] Specifically, when first clamping piece 210 and second clamping piece 220 are close to each other to clamp workpiece, anti-falling driving structure 320 drives support structure 310 to rotate relative to installation component 100, so that the end of support structure 310 away from installation component 100 can be rotated to the bottom of workpiece to support workpiece, so that workpiece can be clamped by first clamping piece 210 and second clamping piece 220, and workpiece can also be supported.

[0045] That is to say, in the clamping mechanism of the application, first clamping piece 210 and second clamping piece 220 are oppositely arranged on installation component 100 for clamping workpiece, and support structure 310 is arranged on installation component 100, support structure 310 is driven by anti-falling driving structure 320, when first clamping piece 210 and second clamping piece 220 clamp workpiece, anti-falling driving structure 320 can drive support structure 310 to rotate to the bottom of workpiece to support workpiece, avoid workpiece to fall off when transferring workpiece subsequently, and support structure 310 can be driven by anti-falling driving structure 320, with high degree of automation.

[0046] In some embodiments, the mounting assembly 100 may include a first mounting member 110 and a second mounting member 120, wherein the second mounting member 120 is disposed on the first mounting member 110, the first mounting member 110 is used for installing the clamping assembly 200 and the anti-fall assembly 300, and the second mounting member 120 is used for connecting the clamping mechanism with an external displacement mechanism.

[0047] In some embodiments, the support structures 310 may be disposed relative to the mounting assembly 100 along a first direction and may be rotatable relative to the mounting assembly 100 .

[0048] See Figure 2 The anti-falling drive structure 320 may include an anti-falling drive member 321 and a transmission member 322. The anti-falling drive member 321 is disposed on the mounting assembly 100. The first end of the transmission member 322 is fixedly connected to the support structure 310, and the second end of the transmission member 322 is rotationally connected to the driving end of the anti-falling drive member 321. The anti-falling drive member 321 drives the second end of the transmission member 322 to move in a second direction. The transmission member 322 is configured to convert the linear motion in the second direction into rotational motion of the support structure 310. The second direction is perpendicular to the first direction.

[0049] It can be understood that since the driving end of the anti-falling driving member 321 is rotationally connected to the transmission member 322, a connecting rod structure can be formed between the driving shaft of the anti-falling driving member 321 and the transmission member 322. When the anti-falling driving member 321 drives the second end of the transmission member 322 to move along the first direction, the first end of the transmission member 322 drives the support structure 310 to rotate relative to the installation assembly 100.

[0050] In the above-mentioned anti-falling drive structure 320, the anti-falling drive component 321 is used in conjunction with the transmission component 322 to convert the linear motion into the direction of rotational motion to drive the support structure 310 to rotate, which can facilitate the setting of the anti-falling drive structure 320, and the structure occupies a small space, and at the same time can avoid interference between the anti-falling drive structure 320 and the clamping assembly 200.

[0051] For example, the anti-falling drive component 321 can be a cylinder, and the drive rod of the cylinder is rotatably connected to the transmission component 322. This type of anti-falling drive component 321 is small in size and can be set on the lower surface of the mounting component 100. It occupies a small space on the lower surface and can avoid interference with the workpiece and the clamping component 200.

[0052] Furthermore, the transmission member 322 can be configured as an arc-shaped structure. The arc-shaped transmission member 322 can reduce the rotation radius of the transmission member 322, thereby reducing the occupied space, while allowing the support structure 310 to have a sufficient rotation angle to ensure that the end of the support structure 310 away from the mounting assembly 100 can be rotated to the bottom of the workpiece.

[0053] See Figure 2 The support structure 310 can include a support member 311, a rotating shaft 312, and a bearing seat 313. The bearing seat 313 is arranged on the mounting assembly 100, the rotating shaft 312 is rotationally connected with the bearing seat 313, the first end of the transmission member 322 is connected with the rotating shaft 312, and the support member 311 is connected with the rotating shaft 312. When the rotating shaft 312 rotates, the end of the support member 311 away from the rotating shaft 312 can rotate to the bottom of the workpiece.

[0054] Specifically, when the anti-falling driving member 321 drives the second end of the transmission member 322 to move in the second direction, the first end of the transmission member 322 drives the rotating shaft 312 to rotate on the bearing seat 313. When the rotating shaft 312 rotates, the support member 311 is driven to rotate.

[0055] Further, the support member 311 can further include a connecting portion 3111 and a supporting portion 3112. The first end of the connecting portion 3111 is connected with the rotating shaft 312, the second end of the connecting portion 3111 is connected with the supporting portion 3112, and an included angle is formed between the supporting portion 3112 and the connecting portion 3111. When the connecting portion 3111 rotates with the rotating shaft 312, the included angle enables the supporting portion 3112 to move to the bottom of the workpiece, so that the supporting portion 3112 can support the workpiece.

[0056] Preferably, the included angle between the supporting portion 3112 and the connecting portion 3111 can be 90°. It can be understood that setting the included angle between the supporting portion 3112 and the connecting portion 3111 to 90° can reduce the angle of rotation of the connecting portion 3111, and at the same time, can enable the supporting portion 3112 to have a large enough supporting surface to support the workpiece.

[0057] Referring to Figure 3 The clamping assembly 200 can further include a first clamping driving member 230. The first clamping driving member 230 is drivingly connected with the first clamping member 210, so that the first clamping member 210 can approach or move away from the second clamping member 220.

[0058] In some embodiments, the first clamping driving member 230 can be a pneumatic cylinder. The pneumatic cylinder can be arranged on the mounting assembly 100.

[0059] Specifically, when the first clamping driving member 230 drives the first clamping member 210 to approach the second clamping member 220, the first clamping member 210 and the second clamping member 220 can cooperate to clamp the workpiece. When the first clamping driving member 230 drives the first clamping member 210 to move away from the second clamping member 220, the first clamping member 210 and the second clamping member 220 can cooperate to release the workpiece.

[0060] Furthermore, in some embodiments, the clamping assembly 200 may also include a second clamping drive member 240, which is arranged on the mounting assembly 100 and is driven and connected to the first clamping drive member 230 so that the first clamping drive member 230 and the first clamping member 210 can be moved closer to or away from the second clamping member 220 as a whole.

[0061] In the above manner, the first clamping driving member 230 is disposed on the mounting assembly 100 through the second clamping driving member 240 and can be driven by the second clamping driving member 240 .

[0062] Specifically, the second clamping drive member 240 can drive the first clamping drive member 230 and the first clamping member 210 to move closer to or away from the second clamping member 220 as a whole, and can adjust the clamping distance between the first clamping member 210 and the second clamping member 220, so that the clamping assembly 200 can clamp workpieces of different lengths, thereby improving the compatibility of the clamping mechanism.

[0063] For example, when the workpiece is long, the second clamping driver 240 can drive the first clamping driver 230 and the first clamping member 210 as a whole away from the second clamping member 220, thereby increasing the initial clamping distance between the first clamping member 210 and the second clamping member 220. When the workpiece is short, the second clamping driver 240 can drive the first clamping driver 230 and the first clamping member 210 as a whole toward the second clamping member 220, thereby decreasing the initial clamping distance between the first clamping member 210 and the second clamping member 220.

[0064] Furthermore, in some embodiments, in order to facilitate the selection of the installation positions of the first clamping drive 230 and the second clamping drive 240, the first clamping drive 230 can be set at a position close to the lower surface of the mounting assembly 100, and the second clamping drive 240 can be set at a position on the upper surface of the mounting assembly 100.

[0065] See Figure 3 In some embodiments, the second clamping drive member 240 may include a motor 241, a screw rod 242 and a sliding block 243. The screw rod 242 is arranged on the mounting assembly 100 and can rotate relative to the mounting assembly 100. The rotating shaft of the motor 241 is connected to the screw rod 242. The sliding block 243 is respectively connected to the screw rod 242 and the first clamping drive member 230. When the screw rod 242 rotates, the sliding block 243 can move on the screw rod 242.

[0066] Specifically, the motor 241 can drive the screw rod 242 to rotate, and when the screw rod 242 rotates, the sliding block 243 can slide along the screw rod 242, and the sliding block 243 drives the first clamping drive member 230 to move during the sliding process. Among them, the sliding block 243 can be a nut of the screw rod 242.

[0067] It can be understood that the above-mentioned screw rod 242 driving structure can improve the overall movement accuracy of the first clamping driving member 230 and the first clamping member 210, and then the clamping distance between the first clamping member 210 and the second clamping member 220 at the initial position can be accurately adjusted according to the length of the workpiece.

[0068] See Figure 3 In some embodiments, when the first clamping drive member 230 is arranged close to the lower surface of the mounting component 100 and the second clamping drive member 240 is arranged on the upper surface of the mounting component 100, a first avoidance hole 130 is provided on the mounting component 100, and the sliding block 243 is connected to the first clamping drive member 230 through the first avoidance hole 130.

[0069] It is understandable that the first avoidance hole 130 can facilitate the connection between the sliding block 243 and the first clamping driver 230 , and at the same time facilitate the sliding block 243 to drive the first clamping driver 230 to move toward or away from the second clamping member 220 .

[0070] Furthermore, an oil receiving member 400 may be provided at a position corresponding to the screw rod 242 in the first avoidance hole 130 , and an oil receiving groove 410 is provided on the oil receiving member 400 .

[0071] The sliding block 243 is provided with a second air-avoiding hole (not shown in the figure), the first clamping member 210 is provided with a third air-avoiding hole (not shown in the figure), and the oil receiving member 400 is penetrated by the second air-avoiding hole and the third air-avoiding hole.

[0072] It is understandable that in order to facilitate the movement of the sliding block 243 on the screw rod 242, the screw rod 242 is generally coated with lubricating oil, which plays a lubricating role when the sliding block 243 moves. However, the lubricating oil on the screw rod 242 may drip, so the oil receiving part 400 is used to receive oil to avoid contamination of the workpiece, etc.

[0073] The second and third air-avoiding holes can prevent the first clamping member 210 and the first clamping driving member 230 from interfering with the oil receiving member 400 .

[0074] Furthermore, in some embodiments, to improve the stability and accuracy of the movement of the first clamping driver 230 and the first clamping member 210 by the second clamping driver 240, a guide rail 270 may be provided on the mounting assembly 100. The guide rail 270 may be located on the mounting assembly 100 on one side of the first clearance hole 130, and the sliding block 243 and the first clamping member 210 are respectively slidably connected to the guide rail 270. This structure allows the sliding block 243 and the first clamping member 210 to share a single guide rail 270, thereby reducing costs and saving space.

[0075] Optionally, the sliding block 243 and the first clamping member 210 may be slidably connected to the guide rail 270 via sliders, respectively.

[0076] See Figure 3 The area on the first clamping member 210 and / or the second clamping member 220 that contacts the workpiece may also be provided with a friction portion 250. The friction portion 250 can exert a friction effect in a direction perpendicular to the clamping direction when the first clamping member 210 and the second clamping member 220 clamp the workpiece, thereby reducing the risk of the workpiece sliding when being clamped.

[0077] In some embodiments, an anti-drop pin 260 is provided on the first clamping member 210 and / or the second clamping member 220. When the first clamping member 210 clamps the workpiece, the anti-drop pin 260 is inserted into the workpiece. The anti-drop pin 260 can provide a certain degree of support to the workpiece in a direction perpendicular to the clamping direction, and can play a role in clamping and positioning.

[0078] See Figure 1 In some embodiments, the clamping mechanism may further include a visual camera 500, which is disposed on the mounting assembly 100 and may be located on a side of the mounting assembly 100. The visual camera 500 is used to detect when the clamping mechanism clamps the workpiece to obtain the accurate position of the workpiece, thereby ensuring that the first clamping member 210 and the second clamping member 220 can accurately clamp the workpiece.

[0079] The clamping mechanism may further include a rangefinder 600. The visual camera 500 is disposed on the mounting assembly 100 and may be located on the side of the mounting assembly 100. The rangefinder 600 is used to measure the distance between the workpiece and the clamping mechanism when the clamping mechanism clamps the workpiece, thereby obtaining the distance between the workpiece and the clamping mechanism and ensuring that the first clamping member 210 and the second clamping member 220 can accurately clamp the workpiece.

[0080] In addition, the present application also provides a transport device, including a displacement mechanism and a clamping mechanism in an embodiment of the present application. The displacement mechanism is driven and connected to the mounting assembly 100 of the clamping mechanism so that the clamping mechanism transfers the workpiece.

[0081] In some embodiments, the displacement mechanism may be a multi-axis robot, an overhead crane, or the like.

[0082] Specifically, the displacement mechanism can drive the clamping mechanism to move to the area where the workpiece is located to clamp the workpiece. After clamping is completed, the displacement mechanism drives the clamping mechanism to transfer the workpiece.

[0083] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of some utility models should be included in the scope of protection of some utility models.
