Description

Technical Field

[0001] The utility model relates to the technical field of battery pack assembly, in particular to a new type of energy storage battery pack box-in mechanism. Background Art

[0002] The assembly of lithium battery industrial and commercial cabinets generally refers to the assembly of PACK batteries inserted into boxes in lithium battery industrial and commercial cabinets. At present, most domestic enterprises use the method of manual stacker for box-in operations; a few enterprises use the method of cooperation between lifting tools and manual labor for operations. The above two methods have low efficiency, high labor costs, and the box-inserting efficiency is reduced due to the influence of human fatigue;

[0003] At the same time, the existing automation equipment can only perform single clamping and box-inserting actions on the battery pack, and the operation path of the equipment needs to be set in advance, which is not flexible enough and prone to faults such as interference. Therefore, a new type of energy storage battery pack box-in mechanism is designed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of energy storage battery pack box-in mechanism, which uses an anti-fooling positioning module composed of a first laser distance sensor, a magnetic switch and an opposed switch to position and prevent fooling of the position of the robot, so that the robot moves to the side of the industrial and commercial cabinet, realizes flexible production, reduces labor costs at the same time, and improves the box-inserting efficiency.

[0005] The utility model provides the following technical solution: a new type of energy storage battery pack box-in mechanism, including a battery box-inserting component and an industrial and commercial cabinet conveying component distributed in parallel. The industrial and commercial cabinet conveying component is used for conveying industrial and commercial cabinets. The battery box-inserting component is located on one side of the industrial and commercial cabinet conveying component.

The anti-fooling module includes a displacement sensor to prevent the industrial and commercial cabinet from colliding by controlling the moving position of the industrial and commercial cabinet. The data detection and transmission module is used to transmit the industrial and commercial cabinet process parameters during the transmission of the industrial and commercial cabinet.

[0010] To enable the industrial and commercial cabinet to interact with the robot and ensure that the chassis is inserted after the industrial and commercial cabinet arrives in place, the control module is connected to both the anti-fooling module and the in-place detection module. The in-place detection module and the anti-fooling module will transmit the in-place signal of the industrial and commercial cabinet to the PLC control program.

Embodiment

[0026] Please refer to Figures 1 to 3 and Figure 5, the present utility model provides a technical solution: a new energy storage battery pack insertion mechanism into a cabinet, which includes a battery insertion box assembly 1 and an industrial and commercial cabinet conveying assembly 2 distributed in parallel. The industrial and commercial cabinet conveying assembly 2 is used to convey the industrial and commercial cabinet 3. The battery insertion box assembly 1 is located on one side of the industrial and commercial cabinet conveying assembly 2. A material rack is further provided at the end of the battery insertion box assembly 1, and a battery pack 6 is placed on the material rack. The battery insertion box assembly 1 is used to grab the battery pack 6 and insert the battery pack 6 into the industrial and commercial cabinet 3. The battery insertion box assembly 1 includes a frame 11, a slide rail 14, a base 5 and a robot 4. The robot 4 is installed on the base 5. A slide rail mounting frame 13 is fixed to the frame 11 through a mounting seat 12. The slide rail 14 is fixed to the slide rail mounting frame 13. A slider 15 slides on the slide rail 14. The base 5 is fixed to the slider 15. A rack 16 is fixed between the slide rails 14. The rack 16 and the slide rail 14 are distributed in parallel. A motor 52 is installed on the base 5. A gear 55 is connected to the output end of the motor 52. The gear 55 meshes with the rack 16. By rotating the motor 52, the base 5 is driven to move along the rack 16.

An anti-fooling positioning module 42, a data recording module 41 and a control module 43 are provided on the manipulator. The anti-fooling positioning module 42 is used to prevent mistakes in the production process to ensure safety and reliability. The anti-fooling positioning module 42 includes a magnetic switch 47, a through-beam switch 48 and a first laser range finder 46. The magnetic switch 47, the through-beam switch 48 and the first laser range finder 46 respectively perform primary positioning, secondary positioning and precise positioning on the robot 4 to control the moving position of the robot 4 so that the position corresponds to the position of the industrial and commercial cabinet, so as to avoid interference between the clamping jaw and other components during clamping.

[0027] The industrial and commercial cabinet conveying assembly 2 includes a in-place detection module 21. The in-place detection module 21 is an in-place sensor 24, and the position of the industrial and commercial cabinet 3 is positioned through the in-place sensor 24.

[0028] The data recording module 41 includes a second laser range finder 49 and a machine vision inspection system 45. The machine vision inspection system 45 acquires images through a camera 53, and the camera 53 is installed on the base 5. The second laser range finder 49 is used to detect and record data during the insertion of the chassis.

The control module 43 includes a PLC control program 44 for controlling the operation of the robot 4. The operation of the robot 4 is driven through the control module 43. At the same time, the machine vision inspection system and the second laser range finder 49 will detect and transmit the data during the operation of the robot 4, and detect and transmit the data of the robot 4 during the insertion of the chassis, further providing technical support for subsequent production through the data, ensuring the stability of subsequent production. Data recording enables the production process to be traceable, providing a process data basis for subsequent product and process reverse research and development.

[0029] As Figure 2 shown, limit switches 18 are fixed at both ends on the side of the slide rail mounting bracket 13. Buffer devices 17 are also fixed at both ends of the slide rail mounting bracket 13. The limit switches 18 are arranged inside the two buffer devices 17. The movement stroke of the robot 4 moving left and right is positioned through the limit switches 18. At the same time, the movement of the robot 4 is buffered by the buffer devices 17 to prevent the robot 4 from making an emergency stop, further affecting the stability of the internal components.

[0030] As Figure 3 shown, the base 5 includes a bottom plate 51. A connecting plate 54 is fixed at the lower end of the bottom plate 51. The connecting plate 54 is connected to the slider 15 through fasteners. The base 5 moves along the slide rail 14 on the slider 15, further enabling the robot 4 to move left and right along the slide rail 14.

[0031] As Figure 4 shown, the industrial and commercial cabinet conveying assembly 2 includes an anti-fooling module 22 and a data detection and transmission module 23. The anti-fooling module 22 includes a displacement sensor 25 to prevent the industrial and commercial cabinet 3 from colliding by detecting the position of the industrial and commercial cabinet 3. The data detection and transmission module 23 is used to detect and transmit the process parameters of the industrial and commercial cabinet 3 during the transmission of the industrial and commercial cabinet 3, providing data support for the subsequent production of the industrial and commercial cabinet 3, and keeping the subsequent production and assembly of the industrial and commercial cabinet 3 stable.

[0032] The control module 43 is connected to both the anti-fooling module 22 and the in-place detection module 21. The in-place detection module 21 and the anti-fooling module 22 will transmit the in-place signal of the industrial and commercial cabinet 3 to the PLC control program 44. The PLC control program 44 verifies and compares the signals. If the comparison is successful, the PLC control program 44 interacts with the robot 4. The robot 4 will perform a mechanical handshaking action, indicating that the industrial and commercial cabinet 3 is in place. The robot 4 can then perform the next production action. A signal command is sent to the robot 4 to control the robot 4 to perform the action of inserting the battery pack 6 into the box.

[0033] The data detection and transmission module 23 is connected to the machine vision detection system 45. The position data of the industrial and commercial cabinet 3 is detected and recorded through machine vision, providing data support for subsequent continuous production and keeping the subsequent production stable.

[0034] A clamping part is installed on the robot 4. Three replaceable fixtures are connected to the clamping part. The three fixtures can respectively clamp the cylindrical, soft-pack, and square-shell battery cells. The clamping part is connected to the control module 43. The clamping part includes a rotating disk. Three fixtures are connected to the rotating disk. By rotating the angle of the rotating disk, the orientation of the fixture is controlled, so that the corresponding fixture can clamp the corresponding model of the battery pack, expanding the compatibility performance in the production and assembly process and providing a relatively reliable guarantee for the optimized production and processing of the product.

[0035] As Figure 6 shown, the flowchart of inserting the battery pack into the box:

[0036] (1) First, transfer the industrial and commercial cabinet to the in-place position. Detect the position of the industrial and commercial cabinet through the in-place detection module and the anti-fooling module to ensure that the industrial and commercial cabinet has moved to the in-place position.

[0037] (2) Subsequently, the in-place detection module generates a signal and transmits the signal to the PLC control program of the control module. Use the PLC control program to make a determination. If the determination is successful, proceed to the next process. If not, transfer the industrial and commercial cabinet again.

[0038] (3) After the determination is successful, the PLC control program transmits a signal to the robot, causing the robot to perform a handshaking action for interaction to ensure that the robot and the control module are successfully matched.

[0039] (4) Detect the assembly area through the machine vision detection system. At the same time, use the anti-fooling positioning module for positioning and anti-fooling to make the robot move to the in-place position. By identifying the characteristics of the battery pack, the robot can replace the fixture according to the battery pack. Use different fixtures to clamp different models of battery packs. Subsequently, the robot performs feature calibration according to the detected data. If the calibration is successful, the robot starts to clamp the battery pack and frictionally assemble the battery pack into the industrial and commercial cabinet. If the calibration is not successful, the manual operation is required to insert the battery pack into the box.

[0040] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present 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 perform equivalent replacements for some of the technical features.
