Description

Technical Field

[0001] The present invention relates to the technical field of formation and grading, and in particular to an automatic integrated machine for the formation and grading of cylindrical battery cells. Background Art

[0002] In the current general trend of the active digital transformation of the manufacturing industry, integrating the warehouse management system (WMS) and the manufacturing execution system (MES) into test equipment has become a key link in achieving efficient collaboration in the production process and quality control. Through this integration mode, the test equipment can carry out in-depth data interaction and business collaboration with WMS and MES. Specifically, the MES system, according to the established production plan, accurately issues test tasks covering detailed information such as test items, standards, and processes to the test equipment, and at the same time transmits associated data such as production orders and product processes to the test equipment, enabling the test equipment to clearly understand the specific requirements of the test object. The WMS system provides the test equipment with the inventory location, batch information, and inbound and outbound records of materials, effectively ensuring that the test equipment can quickly obtain the materials to be tested, and after the test is completed, the materials can be accurately classified and stored and managed according to the test results. After the test equipment completes the test operation, it will timely feedback detailed test data such as performance indicators and defect information to the MES system. The MES system adjusts the production process parameters in a timely manner based on these data, thereby optimizing the production process, effectively avoiding the continuous generation of defective products, and at the same time correlating the test data with the production process data to achieve full traceability of product quality. In addition, the integration can also enable the status information of the test equipment to be uploaded to the MES system in real time, facilitating managers to remotely monitor and maintain the equipment, and significantly improving the utilization rate and reliability of the equipment. This integration method enables enterprises to successfully achieve seamless connection of material flow, information flow, and test data in the production process, greatly improving production efficiency, product quality, and management level, and effectively enhancing the competitiveness of enterprises in the market.

[0003] However, in the production stage of cylindrical battery cells, there are obvious deficiencies in the key link of formation and grading testing. The processes of formation, grading, and handling of cylindrical battery cells are all independent individuals, which results in the inability to achieve seamless connection of material flow, information flow, and test data. Under the existing production mode, after the formation equipment completes the formation of battery cells, there is a lack of a collaborative mechanism based on a unified information flow with the grading equipment and the handling link. During the handling process, information lag or errors are likely to occur for the battery cells, and the formation test data of the battery cells cannot be transmitted to the grading stage in a timely and accurate manner, resulting in the grading equipment being unable to make targeted adjustments based on the formation results, affecting the accuracy and efficiency of grading testing. At the same time, due to the disconnection of the material flow, situations such as misappropriation and misplacement of battery cells may occur during the handling process, and accurate handling and management cannot be carried out based on the inventory information of the WMS system, which not only reduces production efficiency but also makes it difficult to achieve quality traceability of the entire production process of battery cells from formation to grading. This current situation seriously restricts the digital transformation process of cylindrical battery cell production, and an innovative technical solution is urgently needed to solve the above problems and achieve efficient seamless connection of material flow, information flow, and test data during the production process of cylindrical battery cells, improving production efficiency and product quality.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-14 , in the embodiment of the present invention, a cylindrical battery cell formation and grading automatic integrated machine includes a device main body 10, a tray 20 supporting the device main body 10, a pallet 21 for stacking a plurality of trays 20, and a test system 30 for controlling the operation of the device main body 10. A loading unit 40 for receiving the pallet 21 is docked at the front end of the device main body 10, and an unloading unit 50 for sending out the pallet 21 is docked at the rear end of the device main body 10. A stacker 60 for transferring the tray 20 is installed inside the device main body 10, and a plurality of storage locations 11 are respectively arranged on both sides of the stacker 60 inside the device main body 10. A battery cell test module 70 is installed in the storage location 11. The loading unit 40, the unloading unit 50, the stacker 60, and the battery cell test module 70 are controlled by the test system 30; the tray 20 is used to position and place a plurality of battery cells and position the battery cells into the battery cell test module 70 for testing; Both the loading unit 40 and the unloading unit 50 are provided with a double-sided clamping and lifting mechanism 41. The two sides of the material tray 20 are provided with clamping parts 22 docked with the double-sided clamping and lifting mechanism 41. The loading unit 40 lifts the material trays 20 stacked on the tray 21 one by one onto the stacker 60 through the double-sided clamping and lifting mechanism 41. The unloading unit 50 lifts the material trays 20 on the stacker 60 onto the tray 21 through the double-sided clamping and lifting mechanism 41. The stacker 60 is provided with a cargo platform 65 that can extend along both sides. The stacker 60 is docked with the double-sided clamping and lifting mechanism 41 and the battery cell test module 70 respectively through the cargo platform 65. The battery cell testing module 70 is provided with a positioning frame 71 for positioning and placing the material tray 20, a first probe array 72 poweredly connected to the top of the positioning frame 71, and a second probe array 73 poweredly connected to the bottom of the positioning frame 71. The material tray 20 is provided with a fixing groove 23 for positioning and placing the battery cell and a test through hole 24 opened at the bottom of the fixing groove 23. After the material tray 20 is positioned and placed on the positioning frame 71, the first probe array 72 moves down to dock with one end of the battery cell, and the second probe array 73 rises and docks with the other end of the battery cell along the test through hole 24.

[0022] When the cylindrical battery cell automatic capacity conversion machine is working, the loading unit 40 uses the clamping parts 22 on both sides of the material tray 20 through the double-sided clamping and lifting mechanism 41 to lift the material trays 20 stacked on the tray 21 one by one and place them on the stacker 60; the loading platform 65 of the stacker 60 extends along both sides and docks with the double-sided clamping and lifting mechanism 41 to complete the reception of the material tray 20; then, the stacker 60 transfers the material tray 20 to the storage position 11 in the equipment body 10, and at this time, the loading platform 65 docks with the battery cell test module 70; the material tray 20 is positioned and placed on the positioning frame 71 of the battery cell test module 70, and the battery cell is placed in the fixing groove 23 of the material tray 20, and the test through hole 24 is located at the bottom of the fixing groove 23; then, the first The probe array 72 moves downward relative to the positioning frame 71 above the positioning frame 71 and connects to one end of the battery cell. The second probe array 73 rises relative to the positioning frame 71 below the positioning frame 71 and connects to the other end of the battery cell along the test through hole 24, thereby starting to perform formation or capacity separation tests on the battery cell. After the test is completed, the stacker 60 transfers the tray 20 to the unloading unit 50, and the double-sided clamping and lifting mechanism 41 of the unloading unit 50 lifts the tray 20 on the stacker 60 through the clamping part 22 of the tray 20 and places it on the tray 21 to send out the equipment body 10. During the whole process, the loading unit 40, the unloading unit 50, the stacker 60 and the battery cell test module 70 are all controlled by the test system 30.

[0023] From the perspective of achieving automatic integration through structural cooperation, the equipment main body 10, the tray 20, the pallet 21, the loading unit 40, the unloading unit 50, the stacker 60, and the battery cell testing module 70 cooperate with each other and play an important role. The bilateral clamping and lifting mechanism 41 of the loading unit 40 and the unloading unit 50, in cooperation with the clamping parts 22 on both sides of the tray 20, realizes the automatic and precise transfer of the stacked tray 20 between the pallet 21 and the stacker 60 without manual intervention, greatly improving the handling efficiency and accuracy. The load platform 65 of the stacker 60 can extend along both sides and be respectively docked with the bilateral clamping and lifting mechanism 41 and the battery cell testing module 70. This structural design enables the transfer route of the tray 20 inside the equipment to be planned, ensuring the orderly flow of materials. The positioning frame 71 of the battery cell testing module 70 precisely cooperates with the fixing groove 23 of the tray 20, ensuring the stable placement of the battery cell during the testing process. The first probe array 72 and the second probe array 73 respectively conduct tests by docking from both ends of the battery cell, and in cooperation with the test through holes 24 at the bottom of the tray 20, realize the automated operation of the formation and grading test of the battery cell, ensuring the efficiency and accuracy of the test. The close cooperation of these structures enables the entire formation and grading process of the cylindrical battery cell to achieve automatic integration.

[0024] By adopting this automatic integrated machine for the formation and grading of cylindrical battery cells, it can carry out in-depth data interaction and business collaboration with WMS and MES, effectively solving many deficiencies in the formation and grading test link during the production stage of cylindrical battery cells. Among them: In terms of cooperation with the WMS system, the design of this integrated machine innovatively applies the WMS system to the management of battery cell testing. Multiple storage locations 11 are set inside the equipment main body 10, and each storage location 11 is equipped with a battery cell testing module 70. The WMS system provides key information such as the testing location of the battery cells for the integrated machine. After the battery cells enter the equipment, they can be orderly allocated to the corresponding storage locations 11 according to this information and be tested by the corresponding battery cell testing modules 70. This innovative application ensures the tight and orderly progress of the entire testing link, avoids the chaos of the battery cell testing process, and greatly improves the testing efficiency and accuracy. At the same time, the information provided by the WMS system can also assist the integrated machine in optimizing the battery cell handling path, reducing the handling time and energy consumption, and further improving the material flow efficiency. From the perspective of collaboration with the MES system, the MES system, based on the production plan, accurately issues test tasks covering detailed test items, standards, and processes to the test system 30 of the all-in-one machine. During the operation of the all-in-one machine, real-time test data of the battery cells, such as performance indicators and defect information, will be promptly fed back to the MES system. Based on these feedback data, the MES system makes real-time adjustments to the production process parameters, optimizes the production process, and effectively avoids the continuous generation of defective products. At the same time, the operating status information of the all-in-one machine equipment, such as whether the equipment is operating normally and the working conditions of each module, can also be uploaded to the MES system in real time, facilitating remote monitoring and maintenance scheduling of the equipment by management personnel, significantly improving the utilization rate and reliability of the equipment. Through close cooperation with the MES system, the cylindrical battery cell formation and grading automatic all-in-one machine is further integrated into the enterprise's overall production management system, realizing full-process digital and intelligent collaboration from production plan formulation to product production, testing, and quality control. This not only strongly promotes the digital transformation process of cylindrical battery cell production but also greatly improves production efficiency and product quality, enhancing the comprehensive competitiveness of the enterprise.

[0025] Please refer to Figures 6-7 , on the basis of the above technical solution, it is further proposed that the loading unit 40 and the unloading unit 50 further include a rough positioning roller mechanism 42 and a fine positioning roller mechanism 43. The rough positioning roller mechanism 42 in the loading unit 40 is used to send the tray 21 into the equipment main body 10, and the rough positioning roller mechanism 42 in the unloading unit 50 is used to send the tray 21 out of the equipment main body 10. In the loading unit 40 and the unloading unit 50, the rough positioning roller mechanism 42 is usually set to dock with the forklift. During the loading stage, the forklift transports the tray 21 carrying the stacked trays 20 to the rough positioning roller mechanism 42. After the rough positioning roller mechanism 42 receives the tray 21, with its own rolling function, it smoothly sends the tray 21 into the equipment main body 10. During the unloading stage, when the tray 21 completes the relevant processes in the equipment, the rough positioning roller mechanism 42 receives the tray 21 from the equipment main body 10 and transfers it to a position convenient for the forklift to pick up the goods.

[0026] The fine positioning roller mechanism 43 is provided with a limiting mechanism 44. The fine positioning roller mechanism 43 in the loading unit 40 is used to receive the tray 21 transferred by the rough positioning roller mechanism 42, and position the tray 21 through the limiting mechanism 44 for the tray removal operation. In the unloading unit 50, the fine positioning roller mechanism 43 positions the tray 21 through the limiting mechanism 44 for the tray stacking operation, and transfers the fully stacked tray 20 to the rough positioning roller mechanism 42 after it is full; the fine positioning roller mechanism 43 is equipped with a unique limiting mechanism 44. In the loading stage, it receives the tray 21 transferred by the rough positioning roller mechanism 42, and the limiting mechanism 44 acts quickly to accurately position the tray 21, creating stable conditions for the subsequent tray removal operation; in the unloading stage, the fine positioning roller mechanism 43 positions the tray 21 through the limiting mechanism 44 for the tray stacking operation of the tray 20. When the tray 21 is full of the tray 20, it is transferred back to the rough positioning roller mechanism 42 again.

[0027] The bilateral clamping lifting mechanism 41 includes a lifting unit 411 installed in the equipment main body 10 and a bilateral material clamping unit 412 power-connected to the lifting unit 411. The bilateral clamping lifting mechanism 41 clamps the tray 20 through the cooperation of the bilateral material clamping unit 412 and the clamping part 22, and then performs the lifting operation of the tray 20 through the lifting operation of the lifting unit 411. The bilateral clamping lifting mechanism 41 is composed of a lifting unit 411 installed in the equipment main body 10 and a bilateral material clamping unit 412 power-connected thereto; during operation, the bilateral material clamping unit 412 closely cooperates with the clamping parts 22 on both sides of the tray 20 to firmly clamp the tray 20, and then the lifting unit 411 performs the lifting operation to realize the lifting of the tray 20, thereby completing the transfer work of the tray 20 between different positions.

[0028] The docking design of the rough positioning roller mechanism 42 with the forklift greatly optimizes the entire material handling process; the forklift can efficiently transport a large number of trays 21 to the vicinity of the integrated machine, and realize rapid docking and transfer through the rough positioning roller mechanism 42, greatly improving the loading and unloading efficiency of materials, reducing the waiting time, and making the production rhythm more compact; at the same time, the coordinated work of the rough positioning roller mechanism 42 and the fine positioning roller mechanism 43 further improves the accuracy and efficiency of the transfer and positioning of the tray 21; the rough positioning roller mechanism 42 quickly transfers the tray 21, laying a foundation for subsequent fine operations, and the limiting mechanism 44 of the fine positioning roller mechanism 43 ensures the accurate positioning of the tray 21 at key operation nodes, reducing operation errors caused by positioning deviations, and improving the accuracy and stability of the tray removal and stacking operations; the bilateral clamping lifting mechanism 41 through a clever structural design, using the cooperation of the bilateral material clamping unit 412 and the clamping part 22 and the lifting operation of the lifting unit 411, realizes the stable and efficient lifting of the tray 20, effectively avoiding the risk of shaking and dropping of the tray 20 during handling, and further ensuring the smoothness and safety of the entire material handling process.

[0029] Please refer to Figures 8-10 , on the basis of the above technical solution, it is further proposed that the stacker 60 further includes a sky rail 61, a ground rail 62, a horizontal traveling mechanism 63 and a longitudinal traveling mechanism 64. The sky rail 61 and the ground rail 62 are installed inside the equipment main body 10. The horizontal traveling mechanism 63 includes a square frame 631 slidably connected between the sky rail 61 and the ground rail 62, an electric motor 632 installed on the square frame 631, and a rack 633 installed inside the equipment main body 10. The electric motor 632 is power-engaged with the rack 633 to drive the square frame 631 to travel along the sliding direction of the sky rail 61 and the ground rail 62. The longitudinal traveling mechanism 64 includes a linear guide rail 641, a lead screw module 642 and a longitudinal push plate 643.
