Description

Technical Field

[0001] The present application belongs to the technical field of battery processing, and specifically, relates to a carrier device and a laser induced sintering processing device for battery cell processing. Background Art

[0002] During the processing of battery cells, due to the material and thickness of the battery cells, the battery cells themselves are more likely to be broken into pieces during the conveying process. If these pieces fall on the carrier that carries the battery cells and are not cleaned up in time, the next processing will be affected and more battery cell fragments will be generated. In addition, dust or other substances may also appear during the processing of the battery cells. These dust or other substances fall on the carrier that carries the battery cells, which may easily cause the battery cells to be broken into pieces and affect the processing effect of the battery cells. The current existing technology mainly uses air knife blowing or dust extraction to clean the fragments or other substances on the carrier.

[0003] However, the wind knife blowing or dust extraction method may not be able to clean the battery cell fragments or other materials on the carrier in some application scenarios, or even cannot be cleaned. In addition, the wind knife or dust extraction device is generally set at the battery cell processing station, or a special cleaning station is set so that the battery cell stays at the cleaning station and continues to be processed after cleaning. When it is set at the processing station, there may be interference problems, and when it is set at the cleaning station, it may affect the processing rate. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The present application provides a carrying device for battery cell processing, such as Figure 1 , Figure 2As shown, the turntable module 100 includes a rotary drive mechanism (not numbered in the figure), a horizontally arranged support frame 110 and a plurality of carriers 120. The drive shaft of the rotary drive mechanism is vertically arranged and connected to the center of the support frame 110. The plurality of carriers 120 are installed on the support frame 110 and are at equal distances from the center of the support frame 110. The carrier device for processing the battery cell also includes a cleaning module 200. The cleaning module 200 includes a long strip brush 210. The turntable module 100 has at least processing stations B, C and adjacent loading station A and unloading station D. The brush 210 is arranged between the loading station A and the unloading station D, and extends toward the center direction of the support frame 110; the rotary drive mechanism drives multiple carriers 120 to circulate through the loading station A, processing stations B, C and unloading station D in sequence, and in the process of the carrier 120 moving from the unloading station D to the loading station A, the brush 210 cleans the table surface of the carrier 120.

[0022] The rotation drive mechanism is, for example, a DD motor, which can rotate the support frame 110 and multiple carriers 120. The carriers 120 are used to carry the battery cells. The number of the carriers 120 can be multiple, for example, at least three in the embodiment of the present application, and can also be Figure 1 Four or more as shown.

[0023] The present application arranges the brush 210 in the cleaning module between the loading station A and the unloading station D of the turntable module 100, so that during the process of the carrier 120 moving from the unloading station D to the loading station A, that is, during the process of the battery cells on the carrier 120 being taken away and returned to the loading station A empty, the brush 210 cleans the surface of the carrier 120, which does not increase the time required for cleaning the surface, thereby improving work efficiency. The structure and working method of the cleaning module 200 are simple, and the layout of the cleaning module 200 in the entire carrier device for battery cell processing is reasonable. At the same time, since the brush 210 is used to clean the carrier 120, the brush 210 can directly contact and clean the surface of the carrier 120, and the cleaning effect is stronger. Furthermore, compared with the wind knife blowing method, it has a stronger ability to remove battery fragments or other substances.

[0024] It should be noted that when setting the height of the brush 210, the bottom of the brush 210 can be directly set to be lower than or below the surface of the carrier 120, so that when the carrier 120 rotates past the brush 210, the brush 210 will sweep across the surface of the carrier 120. At this time, if there are debris or other substances on the surface of the carrier 120, they will be cleaned up in time. Or, if the carrier 120 does not need or is not suitable to be cleaned with the brush 210 all the time, the brush 210 is connected to a lifting drive actuator 220, and whether to clean the surface of the carrier 120 is selected according to the needs.

[0025] As a preferred embodiment, the cleaning module also includes a lifting drive actuator 220 connected to the brush 210, and the lifting drive actuator 220 drives the brush 210 to rise and fall to move away from or close to the carrier 120. The lifting drive actuator 220 can be, for example, a cylinder. Specifically, the lifting drive actuator 220 can be programmed to set the frequency of the brush 210 cleaning, and whether to lift and lower to achieve cleaning can be selected according to specific needs. When it is necessary to clean the surface of the carrier 120, the lifting drive actuator 220 drives the brush 210 to descend to a position where the bottom of the brush 210 is lower than the surface of the carrier 120 or below, thereby reducing the damage to the surface of the carrier 120 when the brush 210 is constantly cleaning the surface of the carrier 120.

[0026] As another embodiment, the brush 210 is made of non-metallic material or anti-static material, which can effectively prevent static discharge from being generated during the friction process, thereby protecting the battery cell.

[0027] As another embodiment, the cleaning module 200 further includes a support 230 and a guide shaft 240 vertically connected to the support 230 , and the brush 210 is connected to the guide shaft 240 . By setting the guide shaft 240 , the brush 210 can smoothly perform the cleaning process.

[0028] As another embodiment, the length of the brush 210 is equal to the diagonal length of the carrier platform 120 to ensure that the brush 210 can cover the entire surface of the carrier platform 120 during the cleaning process. The length of the brush 210 can be equal to the diagonal length of the carrier platform 120, or slightly greater than the diagonal length of the carrier platform 120, for example, 1.05 to 1.2 times the length of the carrier platform 120.

[0029] As another embodiment, a loading and unloading conveying mechanism is respectively provided corresponding to the loading station A and the unloading station D, and the loading and unloading conveying mechanism and the unloading conveying mechanism work simultaneously. By making the loading and unloading conveying mechanism and the unloading conveying mechanism work simultaneously, when the brush 210 cleans the carrier 120, there are no battery cells on the carrier 120, and the work efficiency can be improved. Figure 1 One of the loading and handling mechanisms is illustrated. The structures of the loading and handling mechanism and the unloading and handling mechanism can be diversified, such as a manipulator with a suction cup. Since its specific structure is not the focus of this application, it will not be described here.

[0030] The present application also proposes a laser induced sintering processing device, comprising a carrier device for processing a battery cell according to any of the above embodiments, and a laser processing module and an electric input module arranged at processing stations B and C, such as Figure 3As shown, the electric input module includes a first electrode 10 and a second electrode 20, and the first electrode 10 and the second electrode 20 are respectively used to electrically contact the positive electrode and the negative electrode of the battery cell, and the laser processing module is used for the electric input module to apply a reverse voltage to the battery cell while scanning the battery cell. Among them, the first electrode can be a strip-shaped probe row, and the probe row includes a bracket and a plurality of probes connected to the bracket in a row. Preferably, the probes are elastic. The second electrode 20 can also be a probe row, or it can be a conductive plate described in the following embodiments. The laser processing module includes a laser and a laser scanning mechanism, the laser is used to emit a laser beam, and the laser scanning mechanism is used to control the scanning direction of the laser beam.

[0031] It should be noted that the laser induced sintering process is generally performed after the process of printing the grid lines on the cell and pre-curing the cells. The laser induced sintering device can improve the contact effect between the metal grid lines and the silicon. By adding the cleaning module 200 to the laser induced sintering device, the cell fragments on the carrier 120 and the sintered materials dropped on the carrier 120 during the laser induced sintering of the grid lines can be better cleaned, thereby reducing the cell fragment rate and reducing the influence of the materials to be cleaned on the laser induced sintering process.

[0032] As another embodiment, the first electrode 10 is arranged above the carrier 120, and the second electrode 20 is a conductive plate arranged on the surface of the carrier 120, wherein the conductive plate is used to carry the battery cell, and the area of ​​the conductive plate carrying the battery cell covers the entire battery cell, and the conductive plate is provided with adsorption holes, and the battery cell is adsorbed and fixed by the adsorption holes to prevent the position of the battery cell from shifting. Among them, when there are only adsorption holes on the conductive plate and no other hollow parts, the debris on the carrier 120, that is, the conductive plate, cannot be effectively removed by wind knife blowing. By using the brush 210, when there are battery cell fragments on the carrier 120 and sintered materials dropped on the carrier 120 during the laser induced sintering of the grid line, they can be effectively cleaned up, and the cleaning effect is good.

[0033] As another embodiment, there are two processing stations, namely the first processing station B and the second processing station C. The first processing station B and the second processing station C are respectively provided with an electric input module, and the first electrode 10 corresponding to the first processing station B is offset relative to the position of the first electrode 20 corresponding to the second processing station C in contact with the battery cell, thereby making the position of the first electrode 10 contacting the battery cell in the first processing station B and the second processing station C and the area where the laser processing module scans the battery cell different, thereby solving the technical problem of the electric input module blocking the laser. The offset here means that the position of the first electrode contacting the battery cell in the first processing station B is different from the position of the first electrode contacting the battery cell in the second processing station C, generally shifted a certain distance laterally. If the turntable module is rotated 90°, for example Figure 1 As shown, the first electrode is further rotated 90°, and the area scanned by the laser processing module at the first processing station B is different from the area scanned by the second processing station C, but the two together complete the scanning of the mutually blocked area, thereby solving the shading problem. The number of lasers in the laser processing module can be one or two.

Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
