[0002] A battery cell refers to a single electrochemical cell containing positive and negative electrodes. It is the energy storage part of a rechargeable battery and is generally not used directly. Its quality directly determines the quality of the rechargeable battery.

[0003] During the production and processing of battery cells, operators attach foam to designated locations on the cells. To improve processing efficiency, collaborative robots are used to automatically attach foam to these locations. These robots have fixtures mounted on their end effectors, allowing them to automatically pick up and attach the foam. However, some collaborative robots require bolts to secure the fixtures during installation. This necessitates the use of tools to remove multiple bolts when the fixtures need to be disassembled for maintenance. This process is time-consuming and labor-intensive, and the bolts can become difficult to remove, further complicating fixture maintenance.

[0004] Therefore, this utility model provides a jig mechanism for an automatic foam bonding collaborative robot for battery cells to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a jig mechanism for an automatic foam bonding collaborative robot for battery cells. It aims to solve the problem that in the prior art, when installing the end effector of some existing collaborative robots, the operator uses bolts to fix the jig. When the jig needs to be disassembled for maintenance, the operator needs to use tools to remove multiple bolts. This operation is time-consuming and laborious, and the bolts may become difficult to remove during use, thus causing inconvenience to the maintenance of the jig.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a jig mechanism for an automatic foam bonding collaborative robot for battery cells, comprising a jig body, a connecting block connected at the center of the top surface of the jig body, one end of the connecting block extending into a connecting groove, the connecting groove being located at the center of the bottom surface of a mounting plate, the top surface of the mounting plate being connected to one end of the collaborative robot, four sets of fixing grooves symmetrically formed on both sides of the connecting block, one end of a fixing rod connected to the inner surface of the fixing groove, the other end of the fixing rod passing through the mounting plate and connected to a movable block, the movable block being connected to the inner surface of the movable groove, the movable groove being symmetrically formed on the bottom surface of the mounting plate, a slot being formed on the front surface of the movable block, and one end of a movable rod connected to the inner surface of the slot.

[0007] As a preferred embodiment of the automatic foam bonding collaborative robot fixture mechanism of this utility model, bearings are embedded on both sides of the inner surface of the mounting plate, and a screw is connected between the two bearings. A movable block is connected through one end of the screw, and the other end of the screw passes through one side surface of the mounting plate and is connected to the screwing block.

[0008] In a preferred embodiment of the automatic foam bonding collaborative robot fixture mechanism for battery cells according to this utility model, the fixed insertion rod is slidably connected to the connecting block through the fixed groove, and the fixed insertion rod is slidably connected to the mounting plate.

[0009] In a preferred embodiment of the automatic foam bonding collaborative robot fixture mechanism of this utility model, the movable block and the screw are connected by a thread, and the movable block is connected to the mounting plate by a movable groove.

[0010] As a preferred embodiment of the automatic foam bonding collaborative robot fixture mechanism of this utility model, the other end of the movable plug is connected to a protrusion, the protrusion is symmetrically embedded on the front surface of the mounting plate, and a spring is provided inside the protrusion through which the movable plug passes, and a pulling block is connected to the surface of the end of the movable plug away from the slot.

[0011] In a preferred embodiment of the automatic foam bonding collaborative robot fixture mechanism of this utility model, the position and size of the slot are matched with the position and size of the movable insert rod, and the movable insert rod forms an elastic structure between the spring and the protrusion.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the interplay of a connecting block, mounting plate, fixed insert rod, screw, movable block, and screwing block. When the fixture body on the end effector of the collaborative robot needs to be disassembled for maintenance, the screwing block is selected to drive the screw to rotate within the bearing. At this time, the movable block on the screw moves the fixed insert rod, causing one end of the fixed insert rod to separate from the fixed groove on the connecting block. The connecting block can then be separated from the mounting plate, allowing the operator to disassemble the fixture body for maintenance without tools, thus saving operation time and bringing convenience to the maintenance operation of the fixture body.

[0014] This invention utilizes the interplay of a slot, a movable rod, a protrusion, a spring, and a pulling block. When the movable block, carrying one end of the fixed rod, is inserted into the fixed groove on the connecting block, the slot on the movable block moves to the position of the movable rod. At this point, the spring elastically pushes one end of the movable rod into the slot on the movable block, thus restricting the position of the movable block and ensuring the stability of the fixed rod after insertion.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides the following technical solution: a jig mechanism for an automatic foam bonding collaborative robot for battery cells, including a jig body 1, a connecting block 2 connected to the middle of the top surface of the jig body 1, one end of the connecting block 2 extending into a connecting groove 3, the connecting groove 3 being opened at the center of the bottom surface of the mounting plate 4, the top surface of the mounting plate 4 being connected to one end of the collaborative robot 5, four sets of fixing grooves 6 symmetrically opened on both sides of the connecting block 2, one end of a fixing rod 7 being connected to the inner surface of the fixing groove 6, the other end of the fixing rod 7 passing through the mounting plate 4 and connected to a movable block 11, the movable block 11 being connected to the inner surface of the movable groove 8, the movable groove 8 being symmetrically opened on the bottom surface of the mounting plate 4, a slot 13 being opened on the front surface of the movable block 11, one end of a movable rod 14 being connected to the inner surface of the slot 13.

[0023] Preferably, bearings 9 are embedded on both sides of the inner surface of the mounting plate 4, and a screw 10 is connected between the two bearings 9. A movable block 11 is connected through one end of the screw 10, and the other end of the screw 10 passes through one side surface of the mounting plate 4 and is connected to the screwing block 12.

[0024] In actual use, when the rotating block 12 is rotated, the rotating block 12 will cause the screw 10 to rotate in the bearing 9, and at this time the position of the movable block 11 on the screw 10 will change.

[0025] Preferably, the fixed insertion rod 7 is slidably connected to the connecting block 2 through the fixed groove 6, and the fixed insertion rod 7 is slidably connected to the mounting plate 4.

[0026] In practical use, when the movable block 11 moves, the movable block 11 will slide along the mounting plate 4 with the connected fixed rod 7, allowing one end of the fixed rod 7 to slide into or separate from the fixed groove 6 on the connecting block 2.

[0027] Preferably, the movable block 11 and the screw 10 are connected by a thread, and the movable block 11 is connected to the mounting plate 4 by a sliding connection through the movable groove 8.

[0028] In practical use, when the screw 10 rotates, the movable block 11 on the screw 10 moves in the movable groove 8 on the mounting plate 4, so that the movable block 11 can reciprocate in the movable groove 8.

[0029] Preferably, the other end of the movable plug 14 is connected to a protrusion 15, the protrusion 15 is symmetrically embedded on the front surface of the mounting plate 4, and the protrusion 15 is provided with a spring 16 that is penetrated by the movable plug 14. The surface of the movable plug 14 away from the slot 13 is connected to a pull block 17.

[0030] In practical use, by pulling the pull block 17, the pull block 17 can slide the movable plug 14 in the protrusion 15, so that the movable plug 14 can squeeze the spring 16 in the protrusion 15. After releasing the pull block 17, the squeezed spring 16 will push the movable plug 14 to slide on the protrusion 15 through elasticity.

[0031] Preferably, the position and size of the slot 13 match the position and size of the movable plug 14, and the movable plug 14 forms an elastic structure between the spring 16 and the protrusion 15.

[0032] In practical use, the movable rod 14 can move elastically in the protrusion 15 via the spring 16. When the movable block 11 with the fixed rod 7 is inserted into the fixed groove 6, the slot 13 on the movable block 11 will move to the position of the movable rod 14. At this time, the spring 16 can elastically push one end of the movable rod 14 into the slot 13 on the movable block 11.

[0033] It should be noted that the bottom of the fixture body 1 is equipped with components such as a vacuum suction cup, a color sensor, and grippers. The vacuum suction cup can pick up the foam at a specified location, the color sensor can detect the foam after it has been pasted, and the grippers can remove the protective film from the foam. The fixture body 1 can be customized to the required shape and size for use.

[0034] Working principle: When using the automatic foam bonding collaborative robot fixture mechanism, the mounting plate 4 is connected to the end effector of the collaborative robot 5 with bolts. Then, the connecting block 2 on the fixture body 1 is slid into the connecting groove 3 on the mounting plate 4. This first pulls the pulling block 17, causing the moving rod 14 to compress the spring 16 in the protrusion 15. At this time, one end of the moving rod 14 will separate from the moving groove 8. Then, the rotating block 12 is rotated, causing the screw 10 to rotate in the bearing 9. At this time, the moving block 11 on the screw 10 will move along the moving groove 8. In this way, the moving block 11 will slide and insert one end of the fixed rod 7 into the fixed groove 6 on the connecting block 2. The position of connecting block 2 is fixed in connecting groove 3. At this time, fixture body 1 can be installed on mounting plate 4, allowing collaborative robot 5 to move with fixture body 1 on mounting plate 4. Simultaneously, when fixed rod 7 is inserted into fixed groove 6, slot 13 on movable block 11 will also move to the position of movable rod 14. At this time, releasing pull block 17 will cause spring 16 to elastically push one end of movable rod 14 into slot 13 on movable block 11, thereby restricting the position of movable block 11 and further ensuring the stability of fixed rod 7 after insertion on movable block 11. This prevents displacement of movable block 11 from affecting the reliability of fixture body 1 installation and ensures the stability of fixture body 1 during operation. At this time, the controller controls the collaborative robot... Robot 5 is programmed according to the production process requirements, setting parameters such as target position, movement path, and speed. The vacuum suction cup on fixture body 1 is then connected to a vacuum generator. This allows the end effector of collaborative robot 5 to move fixture body 1 to the designated location for operation. For example, when attaching foam to the designated location on the battery cell, the end effector of collaborative robot 5 first moves the vacuum suction cup on fixture body 1 to the foam placement position, allowing the suction cup to pick up the foam. Collaborative robot 5 then moves the picked-up foam to the designated location to remove the lower protective film. Once the lower protective film is removed, collaborative robot 5 again moves the foam from fixture body 1 to the battery cell... At the core placement station, the collaborative robot 5, carrying foam from the fixture body 1, attaches it to the designated position on the battery cell. After the foam is attached, the grippers on the fixture body 1 can peel off the upper protective film from the foam. Once the upper protective film is removed, the color sensor on the fixture body 1 detects the attached foam to ensure that the upper protective film is completely removed. This operation allows the collaborative robot 5 to automatically attach foam to the battery cell using the fixture body 1. When the fixture body 1 needs to be disassembled for maintenance, first pull the pull block 17, causing one end of the movable insert rod 14 to separate from the slot 13. Then, rotate the screw block 12 in the opposite direction to make the screw 10 rotate in the opposite direction.The movable block 11 on the screw 10 will cause one end of the fixed insert 7 to separate from the fixing groove 6 on the connecting block 2. At this time, the fixture body 1 can be separated from the mounting plate 4, allowing the operator to disassemble the fixture body 1 without tools, thus saving operation time and facilitating the maintenance of the fixture body 1.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
