Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a cell casing device. Background Technology

[0002] The manufacturing process of lithium batteries requires the insertion of battery cores into the casing, which is the process of pushing the battery cores into the casing. Especially in the field of micro batteries, due to the small size of the batteries, the precision requirements for operations such as the transfer of battery cores, the transfer of casings, and the alignment and insertion of battery cores into the casing are very high. The existing cell insertion equipment is not precise enough, which easily leads to failure of battery core insertion or improper alignment causing damage to the edges of the battery cores. As a result, the defect rate of battery production is high, and the existing equipment can no longer meet the production requirements of lean efficiency, resource conservation, and cost reduction.

[0003] Therefore, researchers in this field urgently need to invent a new battery cell casing device to meet current production needs. Summary of the Invention

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0019] Please see Figure 1 A battery cell loading device (10) includes: a battery cell transfer mechanism (100) for transferring battery cells; a housing loading mechanism (200) for loading and transferring housings; and a housing loading mechanism (300). The housing loading mechanism (300) includes a spacing positioning component (310), a guide component (320), and a pressing component (330). The spacing positioning component (310) is connected to the housing loading mechanism (200). The spacing positioning component (310) is used to perform batch spacing positioning of the housings. The guide component (320) is disposed above the spacing positioning component (310). The battery cell transfer mechanism (100) transfers the battery cells to the guide component (320) to align the battery cells and the housings. The pressing component (330) is used to push the battery cells from the guide component (320) into the housings.

[0020] It should be noted that in the field of micro batteries, the size of the cell and the casing are small, and the movement margin between the cell and the casing is small. The insufficient precision of traditional casing insertion equipment leads to a high defect rate of cell insertion, which directly increases production costs. Therefore, this invention provides a new cell insertion device (10), wherein the casing feeding mechanism (200) sequentially conveys a batch of casings to the spacing and positioning component (310) for spacing and positioning. The spacing and positioning component (310) conveys the batch of casings to the guide component (320), and then the cell moving mechanism is activated to move the cells into the guide component (320), so that each cell is aligned and set in a certain position. Above the housing, the cell and housing are precisely aligned by the combined action of the spacing positioning component (310) and the guide component (320). Then, the pressing component (330) is activated to push the cell into the housing, thus completing the cell insertion operation. The cell insertion device (10) provided by the present invention can improve the alignment accuracy of the cell and housing by the cooperation of the spacing positioning component (310), the guide component (320) and the pressing component (330), thereby improving the cell insertion yield and battery production yield, reducing production costs, and improving the automation level of the production line, thereby improving production efficiency.

[0021] Please see Figure 1 and 2 Furthermore, the spacing positioning assembly (310) includes a support plate (311), a spacing fixture (312), and a spacing drive device (313). The spacing fixture (312) is provided with a plurality of limiting grooves (3121), each limiting groove (3121) being used to accommodate a housing. The support plate (311) is provided with a sliding groove (3111), and the spacing fixture (312) can move in the sliding groove (3111) under the drive of the spacing drive device (313).

[0022] It should be noted that the housing feeding mechanism (200) is located at one end of the support plate (311), and the discharge channel (225) of the housing feeding mechanism (200) is connected to the slide (3111). The guide assembly (320) and the pressing assembly (330) are located at the other end of the support plate (311). Several limiting grooves (3121) on the spacing fixture (312) are arranged at equal intervals. The spacing drive device (313) drives the spacing fixture (312) to slide. The movement of the groove (3111) connects the limiting groove (3121) with the discharge channel (225), so that the shell feeding mechanism (200) pushes the shell into the arranged limiting grooves (3121) in sequence. When the splitting fixture (312) is finished being fed, the splitting drive device (313) drives the splitting fixture to move along the slide (3111) to the working area of ​​the guide component (320). After the guide component (320) senses the splitting fixture (312), it starts to perform the next operation.

[0023] Please see Figure 2and Figure 3 Furthermore, the guide assembly (320) is disposed at one end of the support plate (311). The guide assembly (320) includes a first guide block (321), a second guide block (322), and a guide drive device (323). The first guide block (321) and the second guide block (322) are positioned above the slide groove (3111). The first guide block (321) has a plurality of first grooves (3211), and the second guide block (322) has a plurality of second grooves. When the guide drive device (323) drives the first guide block (321) and the second guide block (322) to fit together, each first groove (3211) and each second groove together form a guide hole. Each guide hole is guided and communicated with a housing.

[0024] It should be noted that when the guide assembly (320) senses that the spacing fixture (312) has moved to the working area of ​​the guide assembly (320), the guide drive device (323) is activated, driving the first guide block (321) and the second guide block (322) to move toward the spacing fixture (312) until the first groove (3211) and the second groove are successively enclosed to form a guide hole, and each guide hole corresponds to a limiting groove (3121); Please see Figure 2 and Figure 3 In one embodiment, the first guide block (321) and the second guide block (322) are mirror-image structures. The sidewalls of the first groove (3211) and the second groove are provided with a guide portion (3211a), a receiving portion (3211b), and a clamping portion (3211c) from top to bottom. When the first groove (3211) and the second groove are closed, the two symmetrical clamping portions (3211c) further clamp and fix the opening end of the housing on the limiting groove (3121). The guide portion (3211a) has… The inclined surface allows the battery cell to fall more smoothly into the receiving part (3211b) when the battery cell transfer mechanism (100) transfers the battery cell to the guide assembly (320). When the battery cell enters the receiving part (3211b), the precise alignment of the battery cell and the housing before entering the housing is completed. There are avoidance holes (3211d) on the guide part (3211a) of the first groove (3211) and the second groove, respectively. The avoidance holes (3211d) are used to avoid the movement of the battery cell when the gripper assembly (120) transfers the battery cell.

[0025] Please see Figure 2In one embodiment, the guide drive device (323) is located below the support plate (311). The guide drive device (323) can be a gripper cylinder, which can drive the first guide block (321) and the second guide block (322) to move simultaneously in a direction that is closer to or farther from each other, thereby improving the movement stability of the first guide block (321) and the second guide block (322). The first guide block (321) and the second guide block (322) are respectively connected to the output end of the gripper cylinder through a transition plate. The two transition plates are respectively located on both sides of the support plate (311). The transition plates can make the overall structure of the guide assembly (320) more compact and small.

[0026] Please see Figure 1 and Figure 4 In one embodiment, the pressing component (330) is disposed on one side of the guide component (320). The pressing component (330) includes a lifting drive device (331), a rotating drive device (332), a pressure plate (333), and a plurality of pressure blocks (334). The plurality of pressure blocks (334) are buffered and disposed on the side of the pressure plate (333) near the guide component (320). Each pressure block (334) is correspondingly disposed with a guide hole. The rotating drive device (332) is used to drive the pressure plate (333) to rotate. The lifting drive device (331) is used to drive the pressure plate (333) to lift, so that the pressure block (334) moves toward or away from the guide hole.

[0027] It should be noted that after the cell transfer mechanism (100) transfers the cell into the guide assembly (320), the rotary drive device (332) is activated, rotating the pressure plate (333) above the guide assembly (320) and aligning the pressure block (334) with the guide hole one by one. Then, the lifting drive device (331) is activated, inserting the pressure block (334) into the guide hole and pushing the cell in the guide hole into the housing. This completes the pushing operation. The guide part (3211a) of the guide hole can provide guidance for the pressure block (334), making it easier to insert into the guide hole. Furthermore, each pressure block (334) can be buffered by a spring to the pressure plate (333). In this way, when the pressure block (334) contacts the cell to complete the pushing operation, it can have a certain buffering effect, avoiding excessive impact force from the pressure block (334) that could damage the cell.

[0028] Please see Figure 5 and Figure 6In one embodiment, the housing feeding mechanism (200) includes a vibratory feeder (210), a feeding platform (220), a pushing component (230), and a defective discharge component (240). The feeding platform (220) is connected to the spacing positioning component (310). The housing flows from the vibratory feeder (210) into the feeding platform (220). The defective discharge component (240) detects the housing and discharges the housings that are determined to be defective from the feeding platform (220). The pushing component (230) pushes and transfers the housings on the feeding platform (220).

[0029] It should be noted that the end face of the casing is generally provided with a QR code, which is usually laser-engraved. The QR code contains information such as the battery manufacturer and production batch. If the QR code is not clear and the finished battery cannot be scanned, the finished battery will be scrapped. In this invention, the QR code on the end face of the casing is first detected by the defective discharge component (240) at the feeding end of the casing. If the QR code cannot be detected, it is defined as defective and discharged. In this way, defective casings will not enter the next preparation process, thus improving production efficiency. Furthermore, the vibrating plate (210) is used to store the casing raw materials in batches. By vibrating, the heavier end of the casing is turned downwards, and the casings will flow out of the vibrating plate (210) in sequence with the open end facing upwards. However, occasionally casings with the open end facing downwards will flow out, which will directly affect the subsequent cell insertion operation. The defective discharge component (240) can also detect the orientation of the casing. When the QR code cannot be detected, it is open downwards. Casings with the open end facing downwards are defined as defective and discharged and recycled in advance.

[0030] Please see Figure 5 and Figure 6 In one embodiment, the defective discharge assembly (240) includes an NG unloading device (241) and a barcode scanning device (242). The NG unloading device (241) is connected to the loading platform (220), and the barcode scanning device (242) is located below the loading platform (220). The loading platform (220) has a barcode scanning area (221) assembled with a light-transmitting material. The sensing area of ​​the barcode scanning device (242) faces the barcode scanning area. 221), the pusher assembly (230) pushes the housing to the barcode scanning area (221) for barcode scanning detection. When the barcode scanning device (242) determines that the housing is a good product, the pusher assembly (230) pushes the good product into the spacing positioning assembly (310). When the barcode scanning device (242) determines that the housing is a defective product, the pusher assembly (230) pushes the defective product onto the NG discharge device (241), and the NG discharge device (241) starts to discharge the defective product.

[0031] It should be noted that a QR code is provided on the end face of the housing. Therefore, by setting a scanning area (221) on the scanning platform, the scanning area (221) is a light-transmitting sheet. The scanning device (242) placed below the scanning area (221) can scan the bottom of the housing through the light-transmitting sheet to detect the QR code. If the scanning device (242) can scan the production information contained in the QR code, the housing is judged to be a good product. The pushing component (230) then pushes the good product into the spacing fixture (312). If the scanning device (242) cannot scan the production information from the QR code, the housing is judged to be a defective product. The NG unloading device (241) then discharges the defective product.

[0032] Please see Figure 5 and Figure 6 In one embodiment, the feeding platform (220) is provided with a feeding channel (222), a first channel (223), a second channel (224) and a discharging channel (225). The feeding channel (222), the first channel (223), the second channel (224) and the discharging channel (225) are connected in sequence. The feeding channel (222) is connected to the vibrating plate (210), and the discharging channel (225) is connected to the spacing positioning component (310). The barcode scanning area (221) is located at the connection between the first channel (223) and the second channel (224). The NG unloading device (241) is located at the connection between the second channel (224) and the discharging channel (225).

[0033] It should be noted that the feeding assembly (230) includes a first feeding component (231), a second feeding component (232), and a third feeding component (233), and the NG discharge device (241) includes an NG drive device (2411), a receiving plate (2412), and an NG funnel (2413). A through groove is provided at the connection between the second channel (224) and the discharge channel (225). The receiving plate (2412) is accommodated in the through groove. The NG drive device (2411) is used to drive the receiving plate (2412) to open or close the through groove. The NG funnel (2413) is located below the through groove. The feeding channel (222) and the first channel (223) are vertically connected, and the intersection of the feeding channel (222) and the first channel (223) is... A pressure sensor (226) is installed at the feed channel (222). When the housing enters the first channel (223) from the feed channel (222), the pressure sensor (226) senses the presence of the housing and sends a signal to the first pusher (231). The first pusher (231) pushes the housing to the barcode scanning area (221) for barcode scanning. After the barcode scanning is completed, the second pusher (232) pushes the housing from the second channel (224) onto the receiving plate (2412). If the housing is detected as defective, the NG drive device (2411) drives the receiving plate (2412) to open the channel, and the defective housing is discharged from the NG funnel (2413). If the housing is detected as good, the third pusher (233) is activated and pushes the housing out of the discharge channel (225).

[0034] Please see Figure 7 In one embodiment, the battery cell loading device (10) further includes a rotary material handling mechanism (800), a short-circuit testing mechanism (900), and a discharge mechanism (1000). The loading mechanism (300), the short-circuit testing mechanism (900), the NG discharge box (80), and the discharge mechanism (1000) are arranged around the rotary material handling mechanism (800). The rotary material handling mechanism (800) is used to transfer the battery cell-containing casing in the loading mechanism (300) to the short-circuit testing mechanism (900) for testing. When the test result is OK, the rotary material handling mechanism (800) transfers the battery cell-containing casing in the short-circuit testing mechanism (900) to the discharge mechanism (1000) for discharge. When the test result is NG, the rotary material handling mechanism (800) transfers the battery cell-containing casing in the short-circuit testing mechanism (900) to the NG discharge box.

[0035] It should be noted that after the battery cells are installed in the casing, they need to go through a material unloading process. Before the unloading process, a short-circuit test is added. The short-circuit test will pick out defective products in advance, preventing them from flowing into the next process, thereby improving production efficiency and reducing production costs.

[0036] Please see Figure 7In one embodiment, the battery cell loading equipment (10) further includes a semi-automatic core loading device (400), a loading pitch adjustment mechanism (500), a tab correction mechanism (600), and a tab bending mechanism (700). The semi-automatic core loading device (400) is used to batch-adsorb and transfer the cores in the tray to the loading pitch adjustment mechanism (500). The loading pitch adjustment mechanism (500) is used to adjust the spacing between the cores. The tab correction mechanism (600) is used to perform a leveling operation on the tabs. The tab bending mechanism (700) is used to bend one end of the tab of the core. In this way, semi-automatic loading of the battery cells and the tab correction and tab bending processes before the battery cells are loaded into the casing can be realized, which improves the automation level of the production line and increases production efficiency.

[0037] Please see Figure 8 In one embodiment, the cell transfer mechanism (100) includes a lateral movement module (110) and several gripper assemblies (120). The loading pitch mechanism (500), the tab correction mechanism (600), the tab bending mechanism (700), and the housing insertion mechanism (300) are arranged in sequence. The lateral movement module (110) is located on one side of the loading pitch mechanism (500), the tab correction mechanism (600), the tab bending mechanism (700), and the housing insertion mechanism (300). Each gripper assembly (120) is located between two adjacent mechanisms. The lateral movement module (110) is used to drive the gripper assembly (120) to complete the cell transfer between the corresponding two adjacent mechanisms.

[0038] In this way, the transfer of battery cells between the feeding pitch mechanism (500) and the tab correction mechanism (600), between the tab correction mechanism (600) and the tab bending mechanism (700), and between the tab bending mechanism (700) and the housing insertion mechanism (300) can be completed through only one battery cell moving mechanism, which can simplify the equipment structure and improve the utilization efficiency of equipment components.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
