[0021] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0022] like Figures 1 to 3As shown, a battery cell drying device includes a conveyor line 1 for linearly conveying battery cells, a drying component 2 located above the conveyor line 1, and a centering positioning mechanism 3.

[0023] Specifically, the drying assembly 2 includes a hollow box 22, in which a plurality of heating tubes are installed. The bottom surface of the box 22 is provided with an exhaust port, and the top surface is provided with an air inlet; a fan 23 is installed at the air inlet.

When in use, under the drive of the motor 343, the two clamping roller frames 32 move closer to or farther from each other, and the final effect is reflected in the two groups of clamping rollers 33 centering or releasing the battery sheet.

[0027] The bracket 31 is provided with a guide rail 311 for guiding the two roller frames 32 to slide, which can ensure the accuracy of the movement of the two roller frames 32 and prevent the belt 341 from being deformed due to gravity.

Among them, the second lifting drive module 42 and the horizontal drive module 43 are preferably electric linear slides.

[0031] In the battery cell drying device, the conveyor line 1 adopts a conventional belt conveyor line, which can ensure the smooth and accurate conveyance of the battery cells.

[0032] The utility model provides a cell drying device. When in use, the screen-printed cell is conveyed to the bottom of the drying assembly 2 via the conveyor line 1, and the drying assembly 2 dries the cell; after drying, the cell is conveyed to between two groups of clamping rollers 33 via the conveyor line 1; under the drive of the driving assembly 34, the two clamping roller frames 32 move toward each other, driving the two groups of clamping rollers 33 to move toward each other so as to realize the centering and positioning of the cell; the unloading mechanism 4 transports the cell after centering and positioning to the feeding position of the stringing machine equipment, ensuring the accuracy of the cell taking position and the stringing placement position, and avoiding adverse effects on the alignment of the cell at the front end of the stringing machine. In addition, the two groups of clamping rollers 33 return to the initial position after centering and positioning the cell, which can facilitate the removal of the cell and reduce the risk of collision and damage of the cell during transportation.
