Description

Technical Field

[0001] The present invention relates to the technical field of battery cell processing, and in particular to an efficient laser processing production line for battery cells. Background Art

[0002] In the current production process of battery cells, laser processing is a key process. However, traditional laser processing equipment and production lines for battery cells have many defects. On the one hand, most production lines only have a single processing station. After the laser completes the processing of a group of battery cells, it needs to wait for the battery cells to be unloaded and a new group of battery cells to be loaded, resulting in a large amount of idle time during this period, seriously affecting the rhythm of laser processing of battery cells and leading to low production capacity. On the other hand, when battery cells are transferred between the loading / unloading stations and the processing station, they are often damaged due to improper operation or unreasonable equipment structure, affecting product quality. Moreover, some existing equipment layouts are loose, occupying a large space, which is not conducive to the efficient development of large-scale industrial production. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an efficient laser processing production line for battery cells, aiming to significantly improve the efficiency of laser processing of battery cells, reduce the risk of battery cell damage, and meet the requirements of large-scale industrial production.

[0004] The technical solution of the present invention is: It includes a workbench, a loading conveyor line and an unloading conveyor line arranged in parallel on the workbench. A processing station is provided between the loading conveyor line and the unloading conveyor line. A laser is correspondingly provided above the processing station. On both sides of the processing station along the battery cell conveying direction, loading / unloading stations are respectively provided. At the same time, on each side, a first moving part for loading and unloading the battery cells on the loading / unloading stations and a second moving part for transferring the battery cells between the loading / unloading stations and the processing station are also provided;

[0005] The second moving part includes a carrier for holding the battery cells, and the carrier moves between the loading / unloading stations and the processing station under the drive of a linear module.

[0006] A further technical solution of it is: The first moving part includes a truss and a material transfer manipulator sliding on the truss, and the truss spans the loading conveyor line and the unloading conveyor line.

[0007] A further technical solution of it is: There are two groups of the material transfer manipulators, which respectively include a loading manipulator for docking the loading conveyor line and the loading / unloading station and an unloading manipulator for docking the loading / unloading station and the unloading conveyor line.

[0008] A further technical solution of it is: The material transfer manipulator includes an adsorption component for adsorbing the battery cells, and several of the adsorption components are rotationally connected to the end of the material transfer manipulator through a rotary motor.

[0009] A further technical solution thereof is that: several groups are also correspondingly provided at the processing stations, and several loading and unloading stations are correspondingly provided on each side of the processing stations, so as to perform laser processing and loading and unloading on multiple battery wafers simultaneously.

[0010] A further technical solution thereof is that: two of the processing stations, the loading and unloading stations on each side of the processing stations, and the adsorption components at the ends of the material transfer manipulators are correspondingly provided. The two processing stations and the two loading and unloading stations on each side of the processing stations are respectively arranged perpendicular to the battery wafer conveying direction.

[0011] A further technical solution thereof is that: a vacuum adsorption plate for holding the battery wafers is provided on the carrier table.

[0012] A further technical solution thereof is that: the linear module includes a driving motor and a slide rail extending along the moving direction of the carrier table. The carrier table is slidably connected to the slide rail through a slider, and drives the battery wafers to move back and forth between the loading and unloading stations and the processing stations under the drive of the driving motor.

[0013] A further technical solution thereof is that:

[0014] It includes the following steps:

[0015] Definition: The two sides of the processing station are respectively the A side and the B side;

[0016] S1: The first moving part on the A side moves the to-be-processed battery wafers on the loading conveyor line to the carrier table at the loading and unloading station on the same side;

[0017] S2: Then, the carrier table on the A side transfers the to-be-processed battery wafers from the loading and unloading station to the processing station for laser processing;

[0018] S3: While the battery wafers on the A side are being laser processed, the first moving part on the B side moves the next group of to-be-processed battery wafers on the loading conveyor line to the carrier table at the loading and unloading station on the same side;

[0019] S4: When the battery wafers on the A side are completed with laser processing, they are transferred from the processing station to the loading and unloading station by the carrier table on the A side. At the same time, the carrier table at the loading and unloading station on the B side transfers the next group of to-be-processed battery wafers to the processing station for laser processing;

[0020] S5: In step S4, the battery wafers transferred from the processing station to the loading and unloading station by the carrier table on the A side after laser processing are picked up by the unloading manipulator on the same side and transferred to the unloading conveyor line to complete unloading.

[0021] The beneficial technical effects of the present invention are as follows: Through an innovative workstation layout, the present invention sets multiple processing workstations and multiple loading and unloading workstations corresponding to the multiple processing workstations respectively arranged on both sides along the conveying direction of the battery wafers. With the coordinated operation of the first moving part and the second moving part on each side, the laser alternately processes multiple battery wafers on both sides, greatly shortening the processing interval time, effectively avoiding the situation of laser idle waiting in the traditional production line, and significantly improving the production capacity per beat of laser processing of battery wafers.

[0022] The first moving part on each side adopts a feeding manipulator and a discharging manipulator with coordinated division of labor, which deeply optimizes the entire feeding process and discharging process of the battery wafers. It not only improves the accuracy and efficiency of the operation, but also enhances the reliability of the entire system during long-term continuous operation.

[0025] The overall production line structure is compact, the layout is reasonable, and each component cooperates efficiently. It fully considers the space utilization in large-scale industrial production and has extremely high practical value and popularization prospects. Description of the Drawings

[0032] In order to better understand the technical means of the present invention and implement it in accordance with the content of the specification, the following further describes in detail the specific implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention but not to limit the scope of the present invention.

[0033] As Figures 1 to 3 shown, an efficient laser processing production line for solar cells according to the present invention includes a workbench 1, a loading conveyor 2 and an unloading conveyor 3 arranged in parallel on the workbench 1. A loading and unloading station 4 and a processing station 5 are arranged side by side between the loading conveyor 2 and the unloading conveyor 3. A laser 6 is correspondingly arranged above the processing station 5.

[0034] The loading conveyor 2 is used to convey the solar cells to be processed, and the unloading conveyor 3 is used to convey the solar cells processed by the laser 6. The loading and unloading station 4 and the processing station 5 are arranged side by side along the conveying direction of the solar cells.

[0035] A first moving part 7 and a second moving part 8 are further arranged between the loading conveyor 2 and the unloading conveyor 3. The first moving part 7 is used to load the solar cells to be processed on the loading conveyor 2 onto the loading and unloading station 4, and to unload the solar cells that have completed laser processing on the loading and unloading station 4 onto the unloading conveyor 3. In this embodiment, the first moving part 7 adopts a material transfer manipulator. The material transfer manipulator moves above the loading conveyor 2, the unloading conveyor 3 and the loading and unloading station 4, and includes an adsorption assembly 71 installed at the end of the material transfer manipulator for adsorbing the solar cells. The second moving part 8 is used to transfer the solar cells between the loading and unloading station 4 and the processing station 5.

[0036] Specifically, the material transfer manipulator is arranged on a truss 9. The truss 9 spans across the loading conveyor 2 and the unloading conveyor 3. The mounting seat of the material transfer manipulator is installed on the guide rail of the truss 9 and moves along the truss 9 under the drive of a linear motor and spans across the loading conveyor 2 and the unloading conveyor 3. When the loading and unloading station 4 is idle, the material transfer manipulator moves the solar cells to be processed on the loading conveyor 2 to the loading and unloading station 4. The second moving part 8 transfers the solar cells from the loading and unloading station 4 to the processing station 5. After the solar cells complete laser processing, they are transferred back to the loading and unloading station 4, and then the material transfer manipulator adsorbs and unloads the solar cells that have completed laser processing onto the unloading conveyor 3.

[0037] Further, as Figure 4 shown, there are at least two groups of the adsorption assemblies 71, and they are rotatably connected to the end of the material transfer manipulator through a rotating motor 72 to simultaneously perform the operations of picking and placing at least two solar cells in the corresponding stations, thereby improving the efficiency of loading and unloading the solar cells.

[0038] Correspondingly, there are at least two loading and unloading stations 4, processing stations 5 and lasers 6 to perform laser processing on at least two solar cells simultaneously.

[0039] In this embodiment, two groups of the adsorption assemblies 71, loading and unloading stations 4, processing stations 5 and lasers 6 are correspondingly provided, and all are matched with the solar cell conveying stations on the loading conveyor 2 and the unloading conveyor 3. The two processing stations 5 are arranged side by side perpendicular to the solar cell conveying direction. During operation, the transfer manipulator moves above the loading conveyor 2. Driven by the rotating motor 72, the two groups of adsorption assemblies 71 rotate 90 degrees to match the solar cell conveying stations on the loading conveyor 2, then adsorb the corresponding solar cells through the suction cups, and then rotate 90 degrees and move to the loading and unloading station 4 to complete the loading.

[0040] The second moving part 8 includes a carrier 81 for carrying the solar cell. A vacuum adsorption plate for holding the solar cell is provided on the carrier 81. The two groups of carriers 81 are fixedly connected through a mounting plate and move between the loading and unloading station 4 and the processing station 5 under the drive of a linear module. Specifically, the linear module includes a driving motor and a slide rail 82 arranged below the mounting plate. The slide rail 82 extends along the moving direction of the carrier 81. Driven by the driving motor, the mounting plate is slidably connected to the slide rail 82 through a slider, and at the same time drives the carrier 81 to move back and forth between the loading and unloading station 4 and the processing station 5, as Figure 5 .

[0041] Furthermore, in order to optimize the process and enhance the system reliability, two groups of transfer manipulators are movably connected to the truss 9, including a loading manipulator for docking the loading conveyor 2 and the loading and unloading station 4 and an unloading manipulator for docking the loading and unloading station 4 and the unloading conveyor 3.

[0042] After the solar cell finishes laser processing, the second moving part 8 transfers the laser-processed solar cell from the processing station 5 to the loading and unloading station 4, and then the unloading manipulator performs unloading. At the same time, after the loading manipulator loads the solar cell to be processed to the loading and unloading station 4, the second moving part 8 transfers the solar cell to be processed to the processing station 5 for laser processing. During the above solar cell loading and unloading process, the laser 6 is in an idle state.

[0043] In this embodiment, in order to further improve the production capacity of the solar cell, loading and unloading stations 4 are respectively arranged on both sides of the processing station 5 along the solar cell conveying direction, and a truss 9 and a transfer manipulator slidably connected to the truss 9 are equipped on each side.

[0044] The steps for the production line of the present invention to complete laser processing are as follows:

[0045] Definition: The two sides of the processing station 5 are respectively the A side and the B side.

[0046] S1: The loading manipulator on the A side moves the wafers to be processed on the loading conveyor line 2 to the carrier table 81 at the loading and unloading station 4 on the same side.

[0047] S2: Then, the carrier table 81 on the A side transfers the wafers to be processed from the loading and unloading station 4 to the processing station 5 for laser processing.

[0048] S3: While the wafers on the A side are being laser processed, the loading manipulator on the B side moves the next set of wafers to be processed on the loading conveyor line 2 to the carrier table 81 at the loading and unloading station 4 on the same side.

[0049] S4: When the wafers on the A side are finished with laser processing, the carrier table 81 on the A side transfers them from the processing station 5 to the loading and unloading station 4. At the same time, the carrier table 81 at the loading and unloading station 4 on the B side transfers the next set of wafers to be processed to the processing station 5 for laser processing.

[0050] S5: In step S4, the wafers transferred to the loading and unloading station 4 by the carrier table 81 on the A side after laser processing are picked up by the unloading manipulator on the same side and transferred to the unloading conveyor line 3 to complete unloading.

[0051] In the above processing steps, the carrier tables 81 on both sides of the processing station 5 alternately slide to the processing station 5 to complete the laser processing of the wafers. That is, after the carrier table 81 on one side is located at the processing station 5 to complete laser processing, it returns to the loading and unloading station 4 for loading and unloading of the wafers, while the carrier table 81 on the other side moves from the loading and unloading station 4 into the processing station 5 for laser processing of the wafers. This structure realizes the simultaneous loading and unloading of wafers on one side and the laser processing of wafers on the other side through the coordinated cooperation between the laser 6 and the first moving part 7 and the second moving part 8 on both sides, ensuring the coherence of the laser processing rhythm of the wafers and the production capacity of the processing production line.

[0052] In this structure, the processing station 5 and the loading and unloading stations 4 on both sides of the processing station 5 are mainly arranged between the loading conveyor line 2 and the unloading conveyor line 3. Among them, the two processing stations 5 and the two loading and unloading stations 4 on each side of the processing station 5 are respectively arranged along the conveying direction perpendicular to the wafers. The width of the entire laser processing production line along the direction perpendicular to the wafer conveying direction is relatively small. Therefore, under the demand of high production capacity, by configuring multiple production lines, the overall structure can also be made compact, and the floor area required for the overall production line can be controlled.

[0053] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
