[0016] A guide member is disposed in the slide groove and is slidably connected to the slide groove. One of the cam member and the guide member is disposed on the side member. The second telescopic component drives and connects the cam member and the other of the guide members so that the guide member switches between the two ends of the slide groove so that the side member abuts against or moves away from the battery module.

[0017] In one embodiment, the mounting bracket comprises:

[0018] First bracket;

[0019] A second bracket having the first end and the second end, the second bracket being slidably connected to the first bracket along the first direction; and

The first telescopic assembly drives the clamping member to slide in the first direction, and the second telescopic assembly itself retracts in the second direction. The edging member is driven to slide in the first direction through the transmission of the reversing mechanism, so that the clamping member and the edging member clamp the battery module when they are close to each other, and the clamping member and the edging member release the battery module when they are far away from each other. The second telescopic assembly changes the transmission direction of the linear motion through the reversing mechanism, so that the second telescopic assembly does not need to be arranged in the first direction, which is conducive to reducing the length of the gripping device in the first direction, reducing the possibility of the gripping device interfering with other equipment during the movement, and improving the passability of the gripping device. The specific grasping process includes: first, the gripper device moves to the top of the battery module, at which time the edging piece and the clamping piece are in a position far away from each other; then, the gripper device moves downward so that the edging piece and the clamping piece are located at both ends of the battery module; then, the second telescopic component is extended and retracted to drive the edging piece close to the battery module and fit with one end of the battery module; finally, the first telescopic component is extended and retracted to drive the clamping piece close to the other end of the battery module, and force is applied to the edging piece to clamp the battery module with the edging piece. If the two clamping pieces are clamped to the middle at the same time, if the midpoints of the two clamping pieces do not coincide with the midpoint of the battery module after moving downward, the battery module will be pushed, which is likely to cause wear of the battery module. In this solution, the edging piece is first fitted with one end of the battery module, and then the clamping piece is used to apply force from the other end of the battery module, which can reduce the possibility of pushing the battery module during the grasping process and reduce the possibility of damage to the battery module. Both the edging piece and the clamping piece can be moved. During the entire downward movement of the gripping device, a certain distance is maintained between the edging piece and the clamping piece and the end portion corresponding to the battery module, thereby preventing the gripping device from colliding with the battery module when moving downward.

[0053] The utility model provides a gripping device.

[0054] See also Figure 1 , Figure 1 A schematic diagram of the structure of an embodiment of the gripper device provided by the utility model Figure 1 .

[0055] In one embodiment of the utility model, the gripper device is used to pick up and place the battery module, and the gripper device includes:

[0056] The mounting bracket 100 has a first end and a second end opposite to each other along a first direction;

[0057] The clamping member 200 is slidably disposed at the first end along the first direction;

[0058] The first telescopic assembly 300 is disposed on the mounting bracket 100 and drives the connecting clamp 200;

[0059] The edge member 400 is slidably disposed at the second end along the first direction;

[0060] A second telescopic assembly 500 is disposed on the mounting bracket 100 and telescopes along a second direction, the second direction being perpendicular to the first direction; and

[0061] The reversing mechanism 600 is transmission-connected to the second telescopic assembly 500 and the edge member 400. The second telescopic assembly 500 drives the edge member 400 to slide along the first direction through the reversing mechanism 600, so as to fit with or separate from one end of the battery module.

[0062] Wherein, by driving the first telescopic assembly 300 and the second telescopic assembly 500 , the clamping member 200 and the edge member 400 move closer to each other to clamp the battery module or move away from each other to release the battery module.

[0063] The gripper device in the technical solution of the utility model comprises a mounting bracket 100, a clamping member 200, a first telescopic assembly 300, a side piece 400, a second telescopic assembly 500 and a reversing mechanism 600. The clamping member 200 and the side piece 400 are slidably arranged at both ends of the mounting bracket 100. The first telescopic assembly 300 drives the clamping member 200 to slide along the first direction, and the second telescopic assembly 500 itself telescopes along the second direction. The side piece 400 is driven to slide along the first direction through the transmission of the reversing mechanism 600, so that the clamping member 200 and the side piece 400 clamp the battery module when they are close to each other, and the clamping member 200 and the side piece 400 release the battery module when they are far away from each other. The second telescopic assembly 500 changes the transmission direction of the linear motion through the reversing mechanism 600, so that the second telescopic assembly 500 does not need to be arranged along the first direction, which is conducive to reducing the length of the gripper device in the first direction, reducing the possibility of interference of the gripper device with other equipment during movement, and improving the passability of the gripper device. The specific grasping process includes: first, the gripping device moves to the top of the battery module, at which time the edging piece 400 and the clamping piece 200 are at a position far away from each other; then, the gripping device moves downward so that the edging piece 400 and the clamping piece 200 are located at both ends of the battery module; then, the second telescopic component 500 is extended and retracted to drive the edging piece 400 to approach the battery module and fit with one end of the battery module; finally, the first telescopic component 300 is extended and retracted to drive the clamping piece 200 to approach the other end of the battery module, and force is applied to the edging piece 400 to clamp the battery module with the edging piece 400. If two clamping members 200 are clamped toward the middle at the same time, if the midpoints of the two clamping members 200 do not coincide with the midpoints of the battery module after the downward movement, the battery module will be pushed, which is likely to cause wear of the battery module. In this solution, the side member 400 is first fitted with one end of the battery module, and then the clamping member 200 applies force from the other end of the battery module, which can reduce the possibility of pushing the battery module during the grasping process and reduce the possibility of damage to the battery module. Both the side member 400 and the clamping member 200 can move, and during the entire downward movement of the gripper device, the side member 400 and the clamping member 200 are kept at a certain distance from the corresponding ends of the battery module to prevent the gripper device from colliding with the battery module when it moves downward.

[0064] Specifically in this embodiment, the first direction is the length direction of the battery module, and the second direction is the height direction of the battery module.

[0065] In one embodiment, the reversing mechanism 600 includes:

[0066] The cam member 610 is provided with a slide groove 611 extending along the second direction, one end of the slide groove 611 is close to the clamping member 200, and the other end of the slide groove 611 is away from the clamping member 200; and

[0067] The guide member 620 is disposed in the slide groove 611 and is slidably connected to the slide groove 611. One of the cam member 610 and the guide member 620 is disposed on the side member 400. The second telescopic component 500 drives the other of the cam member 610 and the guide member 620 to switch the guide member 620 between the two ends of the slide groove 611 so that the side member 400 abuts against or moves away from the battery module.

[0068] Reference Figure 3 and Figure 4 In an embodiment of the utility model, the reversing mechanism 600 includes a cam member 610 and a guide member 620. The cam member 610 is arranged on the edging member 400. The guide member 620 is connected to the second telescopic assembly 500. A slide groove 611 is provided on the cam member 610. The guide member 620 is arranged in the slide groove 611. Since one end of the slide groove 611 is close to the clamping member 200 and the other end is away from the clamping member 200, when the second telescopic assembly 500 drives the guide member 620 to move linearly along the second direction, the guide member 620 will move between the two ends of the slide groove 611, thereby driving the cam member 610 to approach or move away from the clamping member 200 through the inner wall of the slide groove 611, thereby making the edging member 400 approach or move away from the clamping member 200. Specifically in this embodiment, the second telescopic component 500 is extended so that the guide member 620 is in the end of the slide groove 611 away from the clamping member 200, so that the edging member 400 is away from the battery module; the second telescopic component 500 is retracted so that the guide member 620 is in the end of the slide groove 611 close to the clamping member 200, so that the edging member 400 is in contact with the battery module, that is, when the clamping member 200 and the edging member 400 clamp the battery module, the second telescopic component 500 is in a retracted state. The retracted second telescopic component 500 is more secure and stable, and will not continue to retract due to the force of the clamping member, thereby ensuring the stability of the gripping device in clamping the battery module.

[0069] In another embodiment, the guide member 620 is disposed on the edging member 400, and the cam member 610 is connected to the second telescopic assembly 500. The second telescopic assembly 500 drives the cam member 610 to move linearly along the second direction. The guide member 620 moves between the two ends of the slide groove 611, thereby driving the guide member 620 to approach or move away from the clamping member 200 through the inner wall of the slide groove 611, thereby making the edging member 400 approach or move away from the clamping member 200.

[0070] In one embodiment, the mounting bracket 100 includes:

[0071] A first bracket 110;

[0072] A second bracket 120 having a first end and a second end, the second bracket 120 being slidably connected to the first bracket 110 along a first direction; and

[0073] The locking mechanism 130 is disposed on the first bracket 110 and has a locking state for fixing the second bracket 120 and an unlocking state for allowing the second bracket 120 to slide. In the unlocking state, the edging member 400 moves toward the direction close to the clamping member 200 .

[0074] Reference Figure 1 In the embodiment of the utility model, the mounting bracket 100 includes a first bracket 110, a second bracket 120 and a locking mechanism 130. In the unlocked state of the locking mechanism 130, the first bracket 110 and the second bracket 120 can slide relative to each other. The displacement of the edging member 400 is very small when it is attached to the battery module, but there is still a possibility of pushing the battery module to move, which may cause damage to the battery module. Therefore, in this embodiment, the locking mechanism 130 is first in the unlocked state, and the edging member 400 is then moved toward the battery module and attached to one end of the battery module. After the edging member 400 is attached to the battery module, even if the second telescopic assembly 500 is not retracted to its position, the second telescopic assembly 500 continues to retract, and the gripping device is subjected to the reaction force of the battery module, which will cause the second bracket 120 and the second telescopic assembly 500 to slide relative to the first bracket 110 in the first direction as a whole, without pushing the battery module, thereby reducing the possibility of damage to the battery module. After the gripper device grabs the battery module, the first bracket 110 and the second bracket 120 need to be locked by the locking mechanism 130 to prevent the gripper device and the battery module from shaking during movement and colliding with other objects.

[0075] In one embodiment, the locking mechanism 130 includes:

[0076] The sleeve member 131 is provided on the second bracket 120 and is provided with a locking hole;

[0077] The locking pin 132 has one end that is slidably disposed in the first bracket 110 , and the other end of the locking pin 132 is inserted into the locking hole to put the locking mechanism 130 in a locked state, and the other end of the locking pin 132 is withdrawn from the locking hole to put the locking mechanism 130 in an unlocked state.

[0078] Reference Figure 2 In an embodiment of the utility model, the locking mechanism 130 includes a sleeve member 131 and a locking pin 132. The sleeve member 131 is arranged on the second bracket 120, and the locking pin 132 is slidably arranged on the first bracket 110. The locking pin 132 can be inserted into or withdrawn from the locking hole of the sleeve member 131 by sliding. The locking pin 132 is inserted into the locking hole to put the locking mechanism 130 in a locked state, and the locking pin 132 is withdrawn from the locking hole to put the locking mechanism 130 in an unlocked state. The structure is simple and easy to implement.

[0079] In one embodiment, the locking mechanism 130 further includes a third telescopic assembly 133, which is disposed on the first bracket 110 and is driven to connect the locking pin 132; and / or,

[0080] A conical guide structure 1321 is provided at one end of the locking pin 132 facing the locking hole.

[0081] Reference Figure 2 In an embodiment of the utility model, a third telescopic component 133 is provided to drive the locking pin 132, which can accurately control the position of the locking pin 132 and ensure that the locking pin 132 can be accurately inserted into the locking hole, thereby achieving a stable locking of the first bracket 110 and the second bracket 120.

[0082] In the embodiment of the utility model, a conical guide structure 1321 is provided at one end of the locking pin 132 facing the locking hole, so as to facilitate the insertion of the locking pin 132 into the locking hole provided in the sleeve member 131, and the structure is simple and easy to implement. On the other hand, since the displacement of the edging member 400 along the first direction is very small, even if the second bracket 120 slides relative to the first bracket 110 due to the reaction force of the battery module during the process of clamping the battery module, the displacement of the second bracket 120 sliding relative to the first bracket 110 is also small, that is, the misalignment distance between the locking pin 132 and the locking hole is small. Therefore, during the process of inserting the conical guide structure 1321 into the locking hole, the conical surface of the conical guide structure 1321 can directly drive the second bracket 120 to slide again relative to the first bracket 110, so that the locking pin 132 is aligned with the locking hole, and the problem of the locking pin 132 being unable to be inserted into the locking hole will not occur, and there is no need to manually operate the second bracket 120 to slide so that the locking pin 132 is aligned with the locking hole.

[0083] In one embodiment, the gripper device further comprises a pressure sensor, which is disposed on the clamping member 200 and is used to monitor the pressure between the clamping member 200 and the battery module; and / or,

[0084] The gripper device also includes a visual positioning component, which is disposed on the mounting bracket 100 and is used to position the battery module.

[0085] In an embodiment of the utility model, the gripping device also includes a pressure sensor, which monitors the pressure between the clamping member 200 and the battery module, thereby achieving precise control of the clamping force of the gripping device, ensuring that the battery module is not subjected to excessive pressure during the clamping process, thereby reducing the possibility of damage to the battery module. The pressure sensor can be of various types such as capacitive or piezoelectric, as long as it meets the functional requirements, and is not limited here. The pressure sensor can be electrically connected to the first telescopic component 300. If it is detected that the clamping force exceeds a preset safety range, the sensor can control the first telescopic component 300 to stop applying force to ensure the safety of the clamping operation.

[0086] In an embodiment of the utility model, the gripper device also includes a visual positioning component, which can detect and locate the position of the battery module, ensure that the gripper device accurately finds the battery module during the pick-and-place process, realize automatic positioning and grasping of the battery module, reduce manual operations, and improve production efficiency. On the other hand, the visual positioning method is easy to adjust according to the shape and size of the battery module, and is applicable to various types of battery modules. The visual positioning component generally includes a camera and a light source, the camera is used to capture images or videos, and the light source is used to illuminate the battery module so that the camera can capture images clearly.

[0087] In one embodiment, the gripping device further includes a bottom holding mechanism 700, which is disposed on the mounting bracket 100 and is provided with a receiving space with adjustable size. The bottom holding mechanism 700 receives the battery module through the receiving space and supports the bottom of the battery module.

[0088] Reference Figure 1 In an embodiment of the utility model, the gripping device further includes a bottom-covering mechanism 700, which supports the bottom of the battery module, further reducing the possibility of the battery module falling when the gripping device grabs the battery module. The bottom-covering mechanism 700 includes two clamping jaws 710, and a receiving space is formed between the two clamping jaws 710. Each clamping jaw 710 is correspondingly provided with at least one driving component 720. One end of the two clamping jaws 710 is rotatably arranged on both sides of the second bracket 120, and the other end of the two clamping jaws 710 is used to support the bottom of the battery module. The driving component 720 drives the corresponding clamping jaw 710 to rotate to open or shrink the receiving space. The structure is simple and easy to implement. The driving component 720 can be in various forms such as a motor, a cylinder, or an electric push rod. Specifically in this embodiment, the driving component 720 is a cylinder, and the cylinder body of the cylinder is rotatably arranged on the second bracket 120, and the output shaft of the cylinder is connected to the corresponding clamping jaw 710.

[0089] In one embodiment, the gripper device further includes a suction mechanism 800 , which is disposed at the bottom of the mounting bracket 100 and is used to absorb or release the battery module.

[0090] Reference Figure 1In an embodiment of the utility model, the gripper device further includes a suction mechanism 800, and the gripper device sucks the top of the battery module through the suction mechanism 800, further reducing the possibility of the battery module falling when the gripper device grabs the battery module. On the other hand, the suction mechanism 800 can be adjusted according to the shape and size of the battery module, which is convenient for battery modules of different specifications. Among them, the suction mechanism 800 can adopt a variety of methods such as vacuum suction or electromagnetic suction. Specifically in this embodiment, the suction mechanism 800 includes a mounting plate, a vacuum pump, a suction nozzle and a sponge suction cup. The suction nozzle is mounted on the mounting plate and connected to the vacuum pump pipeline. The sponge suction cup is arranged below the mounting plate and has a porous structure inside. When the suction mechanism 800 abuts against the battery module, the air in the porous structure is squeezed out, and the sponge suction cup forms a vacuum adsorption with the battery surface, thereby achieving the suction of the battery module; when the battery module needs to be released, the vacuum pump releases the negative pressure, so that the battery module can be separated from the sponge suction cup.

[0091] In one embodiment, the gripping device further includes a pressing mechanism 900 , which is disposed on the mounting bracket 100 and is drivingly connected to the suction mechanism 800 , and drives the suction mechanism 800 to move so as to drive the battery module into the battery housing.

[0092] Reference Figure 1 In an embodiment of the utility model, the gripper device further includes a pressing mechanism 900, which drives the suction mechanism 800 to press down and press the battery module into the battery housing, thereby avoiding the battery module being stuck and failing to enter the box due to the large friction between the battery module and the battery housing, shortening the time for the battery module to enter the battery housing, and improving production efficiency. On the other hand, the pressing mechanism 900 can easily achieve precise movement through automatic control, so that the speed at which the battery module enters the battery housing is relatively stable, reducing the possibility of damage to the battery module when it is inserted into the battery housing. The pressing mechanism 900 can be in various forms such as a cylinder or an electric push rod, with a simple structure and easy implementation.

[0093] The utility model also provides a battery module boxing device, including the above-mentioned gripper device. The specific structure of the gripper device refers to the above-mentioned embodiment. Since the battery module boxing device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
