Description

Technical Field

[0001] This utility model relates to the field of new energy battery pack production technology, and in particular to a flexible gripping fixture for battery pack production. Background Technology

[0002] The battery pack is the core energy storage component of new energy vehicles, equivalent to the vehicle's "heart." It is responsible for storing electrical energy and providing power to the drive motor, onboard systems, and other components. It not only directly determines the vehicle's range, charging efficiency, and safety, but also integrates a complex management system, making it a key element of new energy vehicle technology.

[0003] As the driving range of new energy vehicles has rapidly increased, this is largely due to the improvement in the energy density of power battery packs. At present, the technological development and manufacturing process of battery cells and battery modules can hardly improve the energy density of the battery system. Therefore, to increase the energy density of the battery pack and meet the requirements of the vehicle's driving range, the battery pack size needs to be larger and larger, with more and larger battery modules, and the internal design of the battery pack needs to be more compact. While the energy density of the battery pack and the driving range of the vehicle have indeed been greatly improved, this has also resulted in very limited internal space and gaps between modules, which are almost entirely occupied by battery modules. Furthermore, the lightweight design has led to most battery packs having intricate reinforcing components inside to strengthen the shell strength and rigidity, further reducing the gaps between adjacent battery modules. This severely limits the space for manual operation, making it extremely difficult to manually or with clamps to handle and place battery modules. In addition, with the increasing size of the battery pack and the increasing weight of the battery modules, the area for manual placement of modules in the middle of the battery pack is quite large, making it difficult to operate with only the length and strength of a human arm.

[0004] For example, the utility model patent with patent application number 202020838670.1 specifically discloses a gripping fixture suitable for power battery pack modules of new energy vehicles, including a robot arm adapter, a vision device set on the robot arm adapter, two gripper devices for gripping the battery module, and a first adjustment device set on the robot arm adapter for adjusting the height of the gripper devices and adjusting the distance between the two gripper devices.

[0005] Although the aforementioned patent solution discloses a first adjustment device for adjusting the height of the gripper device and adjusting the distance between the two gripper devices, the gripping scheme of the gripper device in that patent solution cannot be applied to the battery pack of this application.

[0006] Therefore, there is an urgent need for a structural technology solution that can develop a gripping fixture for the battery pack structure of this application. Utility Model Content

[0007] To address the above problems, this utility model provides a flexible gripping fixture for battery pack production. By using the grooves on both sides of the battery pack as the gripping and fixing reference, and in conjunction with the specific fixed and movable grippers on the gripping fixture, the battery pack can be gripped. Moreover, the movable grippers can be adjusted to adjust the gripping distance between the movable grippers and the fixed grippers, thereby enabling the gripping fixture to grip battery packs of various sizes and models, making it more adaptable.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A flexible gripping fixture for battery pack production includes:

[0010] Connecting flange, fixed gripper, movable gripper and adjusting assembly;

[0011] The connecting flange is connected to an external robotic arm;

[0012] The fixing claw is fixedly installed at one end of the connecting flange, and the fixing claw is arranged perpendicular to the connecting flange.

[0013] The movable gripper is mounted on the other end of the connecting flange relative to the fixed gripper. The movable gripper is arranged perpendicular to the connecting flange and is adjustable relative to the connecting flange.

[0014] The adjustment assembly is mounted on the connecting flange. The adjustment assembly adjusts the movement of the movable gripper relative to the fixed gripper, thereby changing the distance between the fixed gripper and the movable gripper.

[0015] As an improvement, the connecting flange includes a mounting part, a reinforcing part, and a flange part;

[0016] The mounting part is a flat plate, and a moving guide groove is provided on the mounting part for the movable gripper to move.

[0017] The reinforcing part is disposed perpendicular to the mounting part, and the reinforcing part connects the mounting part and the flange part;

[0018] The flange is installed on top of the reinforcing part and is connected to an external robotic arm.

[0019] As an improvement, rubber pads are installed on the sidewalls facing both the fixed gripper and the movable gripper, and these rubber pads are positioned to abut against the battery pack being gripped.

[0020] As an improvement, the rubber pad has protrusions evenly distributed on the sidewall that contacts the battery pack.

[0021] As an improvement, the fixed gripper and the movable gripper have two sets of locking blocks that penetrate the rubber pad in the corresponding areas, and these locking blocks are connected to the grooves on the battery pack.

[0022] As an improvement, the movable gripper is mounted on the lower end face of the mounting part via a connecting plate, and the connecting plate is provided with a slide rail pair for the movable gripper to reciprocate toward the fixed gripper, and a drive member mounted on the connecting plate to drive the movable gripper to move.

[0023] As an improvement, a guide rail clamp is installed on the slide rail of the slide rail pair.

[0024] As an improvement, the adjustment assembly includes a guide rail pair, a lead screw, and a lead screw nut;

[0025] The guide rail pair is installed between the connecting plate and the mounting part;

[0026] The lead screw is rotatably mounted on the mounting part;

[0027] The lead screw nut is sleeved on the lead screw, and the lead screw nut is fixedly connected to the connecting plate through the nut seat passing through the movable guide groove.

[0028] As an improvement, a rail lock is installed on the rail of the guide rail pair.

[0029] As an improvement, a sensor probe is installed on the connecting flange for sensing the grasped battery pack.

[0030] The beneficial effects of this utility model are as follows:

[0031] (1) This utility model uses the grooves on both sides of the battery pack as the gripping and fixing reference, and with the specific fixed claws and movable claws set on the gripping fixture, the battery pack can be gripped. The movable claws can be adjusted to adjust the gripping distance between the movable claws and the fixed claws, so that the gripping fixture can grip battery packs of various sizes and models, and has stronger adaptability.

[0032] (2) By installing rubber pads on the side walls of the fixed and movable clamps that contact the battery pack, the present invention uses rubber pads as flexible contact materials to reduce the rigid contact friction between the fixed and movable clamps and the side walls of the battery pack, thereby avoiding scratches on the side walls of the battery pack. At the same time, it can also avoid the battery pack being clamped and broken due to the rigid clamping force between the fixed and movable clamps.

[0033] (3) By adjusting the movable gripper, the movable gripper can be fixed by the guide rail clamp and guide rail lock when it is not working, so that the movable gripper can be fixed directly when it is not working and will not slide randomly, thus avoiding misoperation.

[0034] In summary, this utility model has the advantages of high automation, strong adaptability, and stable gripping, and is especially suitable for the field of new energy battery pack gripping technology. Attached Figure Description

[0052] Example 1:

[0053] like Figures 1-9 As shown, a flexible gripping fixture for battery pack production includes:

[0054] Connecting flange 1, fixed clamp 2, movable clamp 3, and adjusting assembly 4;

[0055] The connecting flange 1 is connected to an external robotic arm;

[0056] The fixing claw 2 is fixedly installed on one end of the connecting flange 1, and the fixing claw 2 is arranged perpendicular to the connecting flange 1;

[0057] The movable gripper 3 is installed at the other end of the connecting flange 1 relative to the fixed gripper 2. The movable gripper 3 is arranged perpendicular to the connecting flange 1, and the movable gripper 3 is adjustable relative to the connecting flange 1.

[0058] The adjustment component 4 is installed on the connecting flange 1. The adjustment component 4 adjusts the movable jaw 3 to move relative to the fixed jaw 2, thereby changing the distance between the fixed jaw 2 and the movable jaw 3.

[0059] Specifically, the connecting flange 1 includes a mounting part 11, a reinforcing part 12, and a flange part 13;

[0060] The mounting part 11 is a flat plate, and a moving guide groove 111 is provided on the mounting part 11 for the movable gripper 3 to move.

[0061] The reinforcing part 12 is arranged perpendicular to the mounting part 11. The reinforcing part 12 connects the mounting part 11 and the flange part 13. Two sets of reinforcing parts 12 are arranged on opposite sides of the mounting part 11 along its length. The reinforcing part 12 enhances the connection strength between the mounting part 11 and the flange part 13, while ensuring the stability of the mounting part 11 and the flange part 13.

[0062] The flange 13 is installed on the top of the reinforcing part 12. The flange 13 is connected to the external robot arm, and the connecting flange 1 can be quickly connected to the robot arm through the flange 13.

[0063] Furthermore, the movable gripper 3 is mounted on the lower end face of the mounting part 11 via a connecting plate 31, and the connecting plate 31 is provided with a slide rail pair 32 for the movable gripper 3 to reciprocate toward the fixed gripper 2, and a driving member 33 mounted on the connecting plate 31 to drive the movable gripper 3 to move.

[0064] Specifically, the connecting plate 31 and the connecting flange 1 are connected by an adjusting assembly 4. The movable gripper 3, the slide rail pair 32, and the driving component 33 are all mounted on the connecting plate 31. Two sets of slide rail pairs 32 are provided to ensure the stability of the movable gripper 3's movement. The slide rail pair 32 consists of a slide rail 321 and a slider 322. The slide rail 321 is mounted on the connecting plate 31, and the slider 322 slides along the slide rail 321. The movable gripper 3 is installed and connected to the slider 322, so that the movable gripper 3 can slide along the slide rail 321. The driving component 33 is mounted on the connecting plate 31 directly opposite the slide rail 321. The driving component 33 is preferably a cylinder, which pushes the movable gripper 3 to move along the slide rail 321.

[0065] In addition, the adjustment assembly 4 includes a guide rail pair 41, a lead screw 42, and a lead screw nut 43;

[0066] The guide rail pair 41 is installed between the connecting plate 31 and the mounting part 11;

[0067] The lead screw 42 is rotatably mounted on the mounting part 11;

[0068] The lead screw nut 43 is sleeved on the lead screw 42, and the lead screw nut 43 is fixedly connected to the connecting plate 31 through the nut seat 44 and the moving guide groove 111.

[0069] It should be noted that the connecting plate 31 is connected to the mounting part 11 through the guide rail pair 41. There are two sets of guide rail pairs 41, which are composed of guide rail 411 and guide rail slider 412. The guide rail 411 is mounted on the mounting part 11, and the guide rail slider 412 slides along the guide rail 411. The guide rail slider 412 is connected to the connecting plate 31. The two ends of the lead screw 42 are rotatably mounted on the mounting part 11 through the lead screw seat 421. The setting direction of the lead screw 42 is the adjustment direction of the movable gripper 3. The lead screw nut 43 is sleeved on the lead screw 42. The lead screw nut 43 and the lead screw 42 are connected by a thread, and the lead screw nut 43 is connected to the connecting plate 31 through the nut seat 44. The circumferential direction of the lead screw nut 43 is limited by the nut seat 44. The lead screw 42 is driven to rotate by the servo motor. As the lead screw 42 rotates, the lead screw nut 43 moves along the axial direction of the lead screw 42. As the lead screw nut 43 moves, it drives the movable gripper 3 to move, thereby realizing the adjustment of the distance between the movable gripper 3 and the fixed gripper 2 to adapt to the gripping of battery packs of different sizes and specifications.

[0070] Example 2:

[0071] Referring to Example 1, the difference between Example 2 and Example 1 lies in the following:

[0072] like Figure 2 and Figure 5 As shown, rubber pads 20 are installed on the side walls of both the fixed gripper 2 and the movable gripper 3, and the rubber pads 20 are set to abut against the battery pack 00 being gripped.

[0073] Furthermore, the rubber pad 20 has protrusions 211 evenly distributed on the side wall that abuts against the battery pack 00.

[0074] Furthermore, in the areas corresponding to the rubber pad 20 on the fixed gripper 2 and the movable gripper 3, two sets of locking blocks 30 are provided through the rubber pad 20, and these locking blocks 30 are connected to the groove 001 on the battery pack 00.

[0075] It should be noted that the battery pack 00 of this application has several grooves 001 evenly distributed on both sides of its side walls. When the gripping fixture grips the battery pack 00, it uses the grooves 001 as a reference and the locking blocks 30 on the fixed gripper 2 and the movable gripper 3 interlock with the grooves 001 to grip the battery pack 00. During gripping, the rubber pad 20 is in close contact with the side wall of the battery pack 00, which provides elastic cushioning for the battery pack 00 and also fits tightly against the battery pack 00 for gripping. Moreover, the protrusions 211 evenly distributed on the rubber pad 20 can provide good gripping force without scratching the side wall of the battery pack 00.

[0076] Example 3:

[0077] Referring to Example 1, the difference between Example 3 and Example 1 lies in the following:

[0078] like Figures 10-13 As shown, a guide rail clamp 34 is installed on the slide rail 321 of the slide rail pair 32, and the guide rail clamp 34 is connected to the slider 322.

[0079] Furthermore, a guide rail lock 45 is installed on the guide rail 411 of the guide rail pair 41, and the guide rail lock 45 is connected to the guide rail slider 412.

[0080] It should be noted that the guide rail clamp 34 and the guide rail lock 45 have the same structure. The guide rail clamp 34 and the guide rail lock 45 consist of a body 451, two sets of clamping blocks 452 and a handle 453. The body 451 is concave, and the recessed position 454 of the body 451 engages with the slide rail 321 or the guide rail 411. The two sides of the recessed position 454 are provided with mounting grooves 455, and the clamping blocks 452 are installed on the mounting grooves 455. One set of clamping blocks 452 has through holes, and the other set of clamping blocks 452 has through holes. The clamping block 452 has a threaded hole, and the handle 453 has a threaded rod 456. The threaded rod 456 passes through the clamping block 452 with a through hole and is threadedly engaged with the clamping block 452 with a threaded hole on the other side. When the handle 453 is turned, the threaded rod 456 will pull the two sets of clamping blocks 452 closer together through the threaded engagement, clamping the slide rail 321 or guide rail 411, thereby braking the slider 322 or guide rail slider 412 and preventing the movable gripper 3 from being misaligned when it is not working.

[0081] Example 4:

[0082] Referring to Example 1, the difference between Example 4 and Example 1 lies in the following:

[0083] As shown in the figure, a sensor probe 5 is installed on the connecting flange 1. The sensor probe 5 is used to sense the battery pack 00 being grasped.

[0084] It should be noted that in order to ensure that the gripper can accurately grasp the battery pack 00, the sensor probe 5 installed on the connecting flange 1 can sense the battery pack 00. Only after the sensor probe 5 senses the battery pack 00 can the movable gripper 3 be driven to move and cooperate with the fixed gripper 2 to complete the gripping action of the battery pack 00.

[0085] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
