[0032] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0033] Please refer to Figures 1-4 The utility model discloses a gluing device for a battery box bottom plate, comprising:

[0034] A robotic arm 100, wherein the robotic arm 100 is provided with a first connecting portion;

[0035] A gripper 200 is used to grip the bottom plate, and a second connecting portion 240 is provided on the gripper 200;

[0036] The gluing assembly 300 includes a gluing unit for gluing, and the gluing unit is provided with a third connecting portion 321;

[0037] The first connection portion can be detachably connected to the second connection portion 240 and the third connection portion 321 .

[0038] The present application provides a first connection portion on the robot arm 100, a second connection portion 240 on the gripper 200, and a third connection portion 321 on the gluing unit, and enables the first connection portion to be detachably connected to the second connection portion 240 and the third connection portion 321. In this way, the gripper 200 and the gluing unit can share the same robot arm 100, and the same robot arm 100 drives the gripper 200 to grasp the base plate and drives the gluing unit to apply glue, thereby reducing the space occupied by the gluing device and reducing the manufacturing cost of the gluing device.

[0039] Specifically, first connect the first connection part with the second connection part 240, and the robot arm 100 drives the gripper 200 to grab the base plate to the predetermined position to realize the positioning of the base plate. Then the robot arm 100 releases the gripper 200 and connects the first connection part with the third connection part 321. The robot arm 100 drives the gluing unit to apply glue along the predetermined path.

[0040] It should be noted that switching between the robotic arm 100, the gripper 200, and the gluing unit is achieved via a quick-change disk. Specifically, the first connection portion is a quick-change male disk provided on the robotic arm 100, while the second connection portion 240 and the third connection portion 321 are quick-change female disks provided on the gripper 200 and the gluing unit, respectively. By connecting the quick-change male disk to either of the quick-change female disks, the robotic arm 100 can be connected to the gripper 200 or the gluing unit.

[0041] Furthermore, the gluing assembly 300 further includes a gluing platform 310 for placing the bottom plate, and the gluing platform 310 is provided with a first positioning member and a plurality of suction cups 311 for sucking the bottom plate;

[0042] A second positioning member is provided on the bottom plate, and the second positioning member can be connected to the first positioning member.

[0043] The first positioning member is a positioning pin provided on the glue coating platform 310 , and the second positioning member is a positioning hole provided on the bottom plate, and the positioning pin can extend into the positioning hole.

[0044] Specifically, the robot arm 100 drives the gripper 200 to grasp a substrate and move it to the gluing station 310. The positioning pins are inserted into the positioning holes to position the substrate. The suction cups 311 then hold the backside of the substrate, and the gluing unit then applies glue to the front side of the substrate along a predetermined path. This ensures that each substrate is positioned consistently during batch processing, improving gluing quality.

[0045] Furthermore, a placement table 210 for placing the gripper 200 is included.

[0046] The placement platform 210 is provided with a first positioning block, and the gripper 200 is provided with a second positioning block. The first positioning block can abut against the second positioning block.

[0047] A plurality of clamping blocks and a plurality of clamping cylinders are provided on the placement table 210 . The clamping cylinders are extended and retracted to drive the clamping blocks to contact or separate from the gripper 200 .

[0048] Specifically, after the robot arm 100 drives the gripper 200 to place the base plate on the gluing table 310, the gripper 200 releases the base plate, and then the robot arm 100 drives the gripper 200 to move to the placement table 210, and the first positioning block and the second positioning block are offset to realize the positioning of the gripper 200, and then the clamping cylinder drives the clamping block to clamp the gripper 200, and finally the robot arm 100 releases the gripper 200 and leaves, so as to facilitate the subsequent grasping of the gluing unit.

[0049] Furthermore, the gripper 200 is provided with a plurality of gripping blocks 220 and a plurality of gripping cylinders 230 , and the gripping cylinders 230 are used to drive the gripping blocks 220 to grip or release the bottom plate.

[0050] Specifically, the gripper 200 is provided with a plurality of gripping blocks 220 and a plurality of gripping cylinders 230 , and the gripping cylinders 230 drive the gripping blocks 220 to contact or separate from the bottom plate, so as to enable the gripper 200 to grip or release the bottom plate.

[0051] Furthermore, the gluing unit includes a gluing nozzle 330 and a nozzle rack 320 for mounting the gluing nozzle 330 , and the third connecting portion 321 is disposed on the nozzle rack 320 .

[0052] The glue coating assembly 300 further includes a placement rack 340 for placing the nozzle rack 320 .

[0053] Specifically, when the gluing unit is not in use, the nozzle rack 320 is placed on the placement rack 340 to position and place the gluing unit so that the first connection part on the robot arm 100 can be aligned with and connected to the third connection part 321 on the nozzle rack 320 every time.

[0054] Furthermore, a positioning vision camera is provided on the gripper 200 , and the positioning vision camera is used to locate the position of the base plate and guide the gripper 200 to grip the base plate.

[0055] Specifically, before the base plate is coated with glue, it is placed on the feeding cart 400 or elsewhere. At this point, the base plate's position cannot be precisely controlled. Therefore, it is necessary to obtain the precise position of the base plate so that the gripper 200 can grasp it. Based on this, a positioning vision camera is set up to obtain the precise position of the base plate. This position information guides the movement path of the robotic arm 100, allowing the gripper 200 to quickly and accurately grasp the base plate.

[0056] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0057] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0058] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0059] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
