Description

Technical field

[0001] The utility model belongs to the technical field of battery cell manufacturing equipment, in particular to a deviation-correcting mechanism for feeding a half-cell battery through coating. [Background Technology]

[0002] During the production process of battery cells, one of the steps is to accurately place the battery cells into the carrier holes. The size of the battery cells is close to the size of the carrier holes. The hole tolerance is only 10 inches larger than the battery cells on one side. In addition, the battery cells need to be placed into the carrier holes quickly. Therefore, when placing them, they need to be calibrated by the correction mechanism at the bottom before they can be accurately placed in the carrier.

[0003] Patent CN117125463B in the prior art discloses a highly efficient automatic loading system and method for coating battery cells, and further discloses a correction adjustment mechanism for correcting the position of battery cells. The correction adjustment mechanism has two support platforms, each supporting platform corresponding to carrying a half battery cell, and the two support platforms share the same XYR axis drive module. When correcting the position of the battery cells, only a single row can be adjusted simultaneously. After the position of the battery cells on the same row is adjusted and placed on the coating carrier, the position of the other row of battery cells can be adjusted. The double rows of battery cells cannot be corrected and adjusted at the same time, which affects the efficiency of battery cell coating and loading.

[0004] Therefore, it is necessary to provide a new correction mechanism for half-cell coating loading to solve the above technical problems. [Utility Model Content]

[0005] The main purpose of the utility model is to provide a correction mechanism for half-cell coating and loading of batteries. Each battery cell support platform can independently perform position correction adjustment, which can achieve synchronous correction of double rows of battery cells and improve the efficiency of battery cell coating and loading.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions: a correction mechanism for half-cell coating and loading, which includes a first support plate, a pair of lifting drive modules driving the two ends of the first support plate to move up and down, and a plurality of correction modules arranged on the first support plate; the correction module includes a support base plate, a first motor fixed on the support base plate, a second support plate driven by the first motor to move in the X-axis direction, a second motor fixed on the second support plate, a third support plate driven by the second motor to move in the Y-axis direction, a third motor fixed on the third support plate, a rotating rod driven by the third motor to rotate parallel to the Z-axis, and a correction support platform fixed on the top of the rotating rod.

[0007] Furthermore, the correction modules are arranged in double rows on the first support plate.

[0008] Furthermore, a first screw rod and a first slide rail extending along the X-axis direction are provided on the support base plate, and one end of the first screw rod is connected to the driving end of the first motor and is driven to rotate by the first motor.

[0009] Furthermore, the lower surface of the second support plate is provided with a first nut sleeve that cooperates with the first screw rod for transmission and a first sliding block that cooperates with the first slide rail for sliding.

[0010] Furthermore, a second screw rod and a second slide rail extending along the Y-axis direction are provided on the second support plate, and one end of the second screw rod is connected to the driving end of the second motor and is driven to rotate by the second motor.

[0011] Furthermore, the lower surface of the third support plate is provided with a second nut sleeve that cooperates with the second screw rod for transmission and a second sliding block that cooperates with the second slide rail for sliding.

[0012] Furthermore, the deviation-correcting support platform is a rectangular plate structure.

[0013] Furthermore, the deviation-correcting support platform is provided with a plurality of adsorption parts protruding upward.

[0014] Furthermore, the adsorption portion includes a first adsorption portion supporting four right-angle areas of the battery half-sheet and a second adsorption portion supporting a middle area of the battery half-sheet.

[0015] Compared with the existing technology, the beneficial effect of the correction mechanism for half-cell coating and loading of batteries in the utility model is that an XYR three-axis drive structure is independently configured under each correction support platform, so that each correction support platform can independently correct the position of the battery cell. Therefore, all correction support platforms can adjust multiple rows of battery half-cells at the same time, greatly improving the correction efficiency and thus improving the coating loading efficiency.

[Specific implementation method]

[0025] Example 1:

[0026] Please refer to Figure 1-Figure 4 This embodiment is a correction mechanism 100 for loading half-cell battery coating, which includes a first support plate 1, a pair of lifting drive modules 2 for driving the two ends of the first support plate 1 to move up and down, and a plurality of correction modules 3 arranged on the first support plate 1.

[0027] All the deviation correction modules 3 are arranged in double rows on the first support plate 1 , and the positions of the two rows of battery half-cells are corrected and adjusted at the same time, thereby improving the deviation correction efficiency.

[0028] The correction module 3 includes a support base 31, a first motor 32 fixed on the support base 31, a second support plate 33 driven by the first motor 32 to move in the X-axis direction, a second motor 34 fixed on the second support plate 33, a third support plate 35 driven by the second motor 34 to move in the Y-axis direction, a third motor 36 fixed on the third support plate 35, a rotating rod 37 driven by the third motor 36 to rotate parallel to the Z-axis, and a correction support platform 38 fixed on the top of the rotating rod 37.

[0029] The support base 31 is provided with a first screw rod 39 and a first slide rail 310 extending along the X-axis. One end of the first screw rod 39 is connected to the driving end of the first motor 32 and is driven to rotate by the first motor 32. The lower surface of the second support plate 33 is provided with a first nut sleeve 311 that cooperates with the first screw rod 39 for transmission, and a first slider 312 that slides in cooperation with the first slide rail 310.

[0030] The second support plate 33 is provided with a second screw rod 313 and a second slide rail 314 extending along the Y-axis direction. One end of the second screw rod 313 is connected to the driving end of the second motor 34 and is driven to rotate by the second motor 34. The lower surface of the third support plate 35 is provided with a second nut sleeve 315 that cooperates with the second screw rod 313 for transmission, and a second slider 316 that cooperates with the second slide rail 314 for sliding.

[0031] The correction support platform 38 is a rectangular plate slightly smaller than the battery cell half. It is equipped with several upwardly protruding suction points 381. These suction points 381 include a first suction point that supports the four right-angled areas of the battery cell half and a second suction point that supports the center of the cell half. These suction points 381 provide multi-point support for the battery cell half, preventing large-area contact with the substrate surface and reducing the risk of scratches on the cell substrate.

[0032] During use, the transport mechanism adsorbs and transports the double-row battery half-cells from the conveyor line to the coating carrier, and then takes pictures of the position of the battery half-cell on the coating carrier through the camera. The correction support platform 38 passes upward through the hollow groove on the coating carrier, lifts the battery half-cell upward and separates it from the coating carrier. At the same time, the battery half-cell is adsorbed and fixed by the corresponding adsorption holes to prevent the battery half-cell from shifting during the correction adjustment process or when it is placed back into the coating carrier support slot; under the joint action of the first motor 32, the second motor 34 and the third motor 36, the battery half-cell on the correction support platform 38 is adjusted in the XYR axis direction, so that the position of the battery half-cell in the coating carrier support slot meets the requirements, thereby realizing automatic correction.

[0033] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
