Technical Field

[0001] This utility model belongs to the field of automated and precise positioning technology of battery module tray screws, specifically relating to an automated and precise positioning device for battery module tray screws. Background Technology

[0002] The automated precision positioning device for battery module tray screws is mainly used in the production process of new energy batteries to realize the automated gripping, positioning, positioning and fastening of battery module tray screws. It solves the problems of low efficiency, poor positioning accuracy and insufficient consistency of traditional manual operation, and improves the automation level and production quality of battery module assembly.

[0003] Currently, existing automated precision positioning devices for battery module tray screws typically use an industrial camera to capture the position of the tray screw holes and images of the screw in real time. Then, a pneumatic clamp at the end of a multi-axis robotic arm is used to clamp the screw and insert it into the tray screw hole for precise positioning. However, in traditional automated precision positioning devices for battery module tray screws, the industrial camera on the robotic arm is usually fixed with screws. Therefore, operators need to use tools to install it, and it also takes a lot of time to disassemble and adjust the industrial camera, thus reducing the maintenance efficiency of the automated precision positioning device for battery module tray screws. Utility Model Content

[0004] The purpose of this invention is to provide an automated and precise positioning device for battery module tray screws. This addresses the problem that existing automated and precise positioning devices for battery module tray screws typically use an industrial camera to capture the position of the tray screw holes and images of the screw in real time. The screw is then clamped into the tray screw holes using a pneumatic clamp at the end of a multi-axis robotic arm to achieve precise positioning. However, in traditional automated and precise positioning devices for battery module tray screws, the industrial camera on the robotic arm is usually fixed with screws. Therefore, installation requires tools, and disassembling and adjusting the industrial camera also takes considerable time, thus reducing the maintenance efficiency of the automated and precise positioning device for battery module tray screws.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated and precise positioning device for a battery module tray screw, comprising a mounting base, a multi-axis collaborative robotic arm mounted on the top of the mounting base, a mounting frame fixedly connected to one end of the multi-axis collaborative robotic arm, a pneumatic clamp mounted on one end of the mounting frame, and an industrial camera mounted on one side of the mounting frame.

[0006] The industrial camera has a connecting harness connected to its back. A positioning block is fixedly connected to the outer wall of the industrial camera. A limit slot is formed on the outer wall of the positioning block. A mounting frame is fixedly connected to one side of the mounting bracket. A positioning groove is formed on the outer wall of the mounting frame. Two mounting seats are symmetrically distributed on the outer wall of the mounting frame. A pull rod is inserted through one end of each of the two mounting seats. A movable block is connected to one end of the pull rod. A limit pin is fixedly connected to one end of the movable block. A spring is sleeved on the end of the pull rod.

[0007] As a preferred embodiment of the automated and precise positioning device for battery module tray screws of this utility model, the industrial camera positioning block, limit slot, mounting frame, positioning groove, mounting base, pull rod, movable block, limit pin, and spring can form an elastic engagement structure with the mounting frame.

[0008] In a preferred embodiment of the automated and precise positioning device for the battery module tray screw of this utility model, the end of the limiting pin away from the movable block is adapted to the size of the limiting slot.

[0009] In a preferred embodiment of the automated and precise positioning device for the battery module tray screw of this utility model, one end of the positioning block is located inside the positioning groove.

[0010] In a preferred embodiment of the automated and precise positioning device for the battery module tray screw of this utility model, the two mounting seats are symmetrically distributed.

[0011] In a preferred embodiment of the automated and precise positioning device for the battery module tray screw of this utility model, the industrial camera is located in the inner groove of the mounting frame.

[0012] As a preferred embodiment of the automated and precise positioning device for the battery module tray screw of this utility model, the outer wall of the mounting frame is provided with a groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Pulling the lever at both ends of the movable block causes the limit pin to retract, and then the industrial camera is placed into the mounting frame slot. At this time, the positioning block will be embedded in the positioning slot. Then, by releasing the lever, the limit pin can be ejected by the spring and inserted into the limit slot, thus facilitating the installation and fixation of the industrial camera. During disassembly and maintenance, pulling the lever at both ends of the movable block causes the limit pin to retract, allowing the limit pin to disengage from the limit slot on the outer wall of the positioning block. Then, pulling the industrial camera outward allows it to be removed from one side of the mounting frame, facilitating subsequent disassembly and adjustment and improving maintenance convenience.

[0015] By using a mounting frame, positioning blocks, and positioning slots, the positioning blocks on the outer wall of the industrial camera can be embedded into the positioning slots when installing the industrial camera, thereby improving the installation stability of the industrial camera.

[0022] 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.

[0023] Please see Figures 1-4 The present invention provides the following technical solution: an automated and precise positioning device for a battery module tray screw, including a mounting base 1, a multi-axis collaborative robotic arm 2 mounted on the top of the mounting base 1, a mounting frame 3 fixedly connected to one end of the multi-axis collaborative robotic arm 2, a pneumatic clamp 4 mounted on one end of the mounting frame 3, and an industrial camera 5 mounted on one side of the mounting frame 3.

[0024] The industrial camera 5 has a connecting wire harness 6 connected to its back. A positioning block 7 is fixedly connected to the outer wall of the industrial camera 5. A limit slot 8 is opened on the outer wall of the positioning block 7. A mounting frame 9 is fixedly connected to one side of the mounting bracket 3. A positioning groove 10 is opened on the outer wall of the mounting frame 9. Two mounting seats 11 are symmetrically distributed on the outer wall of the mounting frame 9. A pull rod 12 is inserted through one end of the two mounting seats 11. A movable block 13 is connected to one end of the pull rod 12. A limit pin 14 is fixedly connected to one end of the movable block 13. A spring 15 is sleeved on the end of the pull rod 12.

[0025] Preferably, the industrial camera 5 positioning block 7, limiting slot 8, mounting frame 9, positioning groove 10, mounting base 11, pull rod 12, movable block 13, limiting pin 14, and spring 15 can form an elastic engagement structure with the mounting frame 3. The two mounting bases 11 are symmetrically distributed, and the end of the limiting pin 14 away from the movable block 13 is adapted to the size of the limiting slot 8.

[0026] In practical use, the pull rod 12 pulls the movable blocks 13 connected at both ends to retract the limit pin 14, and then the industrial camera 5 is placed into the inner groove of the mounting frame 9. At this time, the positioning block 7 will be embedded in the positioning groove 10. Then, by releasing the pull rod 12, the limit pin 14 can be popped out under the action of the spring 15 and inserted into the limit slot 8, thus facilitating the installation and fixation of the industrial camera 5. During disassembly and maintenance, the pull rod 12 pulls the movable blocks 13 connected at both ends to retract the limit pin 14, so that the limit pin 14 can be disengaged from the limit slot 8 on the outer wall of the positioning block 7. Then, the industrial camera 5 can be pulled outward to remove it from one side of the mounting frame 3, which facilitates subsequent disassembly and debugging and improves maintenance convenience.

[0027] Preferably, the industrial camera 5 is located in the inner groove of the mounting frame 9, and one end of the positioning block 7 is located inside the positioning groove 10.

[0028] In practical use, by setting up the mounting frame 9, positioning block 7 and positioning groove 10, when installing the industrial camera 5, the positioning block 7 on the outer wall of the industrial camera 5 can be embedded into the positioning groove 10 to play a positioning role, thereby improving the installation stability of the industrial camera 5.

[0029] Preferably, the outer wall of the mounting frame 9 has a groove 16.

[0030] In practical use, the groove 16 facilitates the connection between the industrial camera 5 and the connecting harness 6.

[0031] It should be noted that the other end of the connecting harness 6 is connected to an external device.

[0032] Working principle: First, the pull rod 12 pulls the movable block 13 connected at both ends, causing the limit pin 14 to retract. Then, the industrial camera 5 is placed into the inner groove of the mounting frame 9. At this time, the positioning block 7 will be embedded in the positioning groove 10. Then, by releasing the pull rod 12, the limit pin 14 can be ejected under the action of the spring 15 and inserted into the limit groove 8, thus facilitating the installation and fixation of the industrial camera 5. Through the setting of the mounting frame 9, positioning block 7, and positioning groove 10, when installing the industrial camera 5, the positioning block 7 on the outer wall of the industrial camera 5 is embedded in the positioning groove 10 to play a positioning role, thereby improving the installation stability of the industrial camera 5. Then, the industrial camera 5 takes pictures of the tray screw hole position and the tray screw, and the algorithm calculates the difference between the actual position of the screw and the standard position. The control system generates the robotic arm's motion trajectory based on the deviation data of the X / Y / Z axis offset and rotation angle θ. Then, the pneumatic clamp 4 at the end of the multi-axis collaborative robotic arm 2 is operated to grip the screw. The robotic arm moves along the planned path, and the screw is inserted into a "soft contact" state through the force control system. The force and angle are adjusted in real time to ensure that the screw is vertically aligned with the hole and screwed in to the preset torque, thereby realizing the automated and precise return of the battery module tray screw. Finally, during disassembly and maintenance, the pull rod 12 pulls the movable block 13 connected at both ends to drive the limit pin 14 to retract, so that the limit pin 14 can disengage from the limit slot 8 on the outer wall of the positioning block 7. Then, the industrial camera 5 can be pulled outward to remove it from one side of the mounting bracket 3, which facilitates subsequent disassembly and debugging and improves maintenance convenience.

[0033] 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.
