The output shaft of each control cylinder 307 is rotatably connected to the other end of one of the drive plates 305.

[0026] As a technical optimization of this utility model, the drive plate 305 on the control cylinder 307 has an "L" shaped structure. The drive plate 305 is located at the center line of the mounting plate 301, which is conducive to the control cylinder 307 controlling the swing of the drive plate 305, thereby realizing the opening and closing of the cover plate 302.

[0027] As a technical optimization of this utility model, multiple sets of guide rails 303 are installed on both sides of the mounting frame 1. Two sliders 304 are slidably connected to the guide rails 303 respectively. Multiple mounting plates 301 are slidably connected to the guide rails 303 through the sliders 304. The mounting plates 301 are slidably connected to the mounting frame 1. Through the cooperation of the guide rails 303 and the sliders 304, the mounting plates 301 and the mounting frame 1 can slide, which facilitates the closing of the cover plate 302 and pushes it to make the cover plate 302 close tightly. At the same time, after the cover plate 302 is opened, it can slide to a certain position, which makes it easy for the cover plate 302 to be temporarily placed on top of another cover plate 302.

[0028] As a technical optimization of this utility model, multiple adjusting cylinders 306 are installed on both sides of the mounting bracket 1. The output shafts of the multiple adjusting cylinders 306 are respectively connected to the mounting plate 301. By adjusting the installation of the cylinders 306, it is easier to control the movement position of the mounting plate 301, making the operation more convenient and flexible.

[0029] As a technical optimization of this utility model, multiple reinforcing ribs 201 are installed on the outside of the heating box 203. The reinforcing ribs 201 are made of square tubular carbon steel. The installation of multiple reinforcing ribs 201 helps to strengthen and protect the heating box 203, making the heating box 203 more solid and stable.

[0030] As a technical optimization of this utility model, multiple insulation boards 6 are installed on the inner side of the mounting frame 1. The insulation boards 6 abut against the outer side of the reinforcing ribs 201. The installation of the insulation boards 6 is beneficial for heat preservation of the heating box 203, reducing heat loss and increasing the temperature.

[0031] As a technical optimization of this utility model, multiple ventilation plates 202 are installed inside the multiple heating boxes 203 respectively, and multiple guide plates 204 are installed on one edge of the ventilation plate 202.

The baffle 308 is slidably connected to the inner side of the cover plate 302 by multiple compression springs 313. The outer side of the baffle 308 abuts against the heating box 203. By installing multiple compression springs 313, the baffle 308 and the cover plate 302 can slide with elasticity, which is beneficial to tightly close the heating box 203.

[0033] As a technical optimization of this utility model, a positioning groove 309 is provided at the center of the baffle 308, and a positioning block 310 is installed at the center of the heating box 203. The positioning block 310 is engaged with the positioning groove 309. After the cover plate 302 and the heating box 203 are closed by the installation of the positioning block 310, the positioning groove 309 on the baffle 308 is engaged with the positioning block 310, thereby achieving the function of positioning the cover plate 302.

The installation of the blocks 311 facilitates the opening of the guide grooves 312. The sliding of the multiple guide rods 314 with the inside of the guide grooves 312 achieves the function of guiding and limiting the baffle 308. The baffle 308 slides smoothly with the inside of the cover plate 302.

[0035] In use, this invention first stacks multiple heating boxes 203 on the mounting frame 1 as needed, enabling sequential feeding and heating of multiple battery cells, thus improving production efficiency. Through the cooperation of the air supply assembly 4 and the vacuum assembly 5, air is supplied to the interior of the heating box 203 and moisture is removed. With the assistance of the ventilation plate 202, hot air is evenly delivered into the heating box 203. The installation of multiple mounting plates 301 facilitates the installation of multiple control cylinders 307. The operation of the multiple control cylinders 307 drives multiple drive plates 305, which in turn drives multiple cover plates 302, closing the cover plates 302 with the heating box 203 for easy heating. The re-operation of the control cylinders 307 pulls the drive plates 305 onto the cover plates 302, achieving... The cover plate 302 and the heating box 203 are opened to facilitate loading and unloading. Only one cover plate 302 on the heating box 203 can be opened for loading at the same time. After loading is completed, the automatic drive control cylinder 307 closes the cover plate 302 to realize the heating of the battery cell. After heating is completed, the automatic control of the cover plate 302 opens, and a robot or stacker crane performs the unloading operation. At the same time, the cooperation of the guide rail 303 and the slider 304 facilitates the sliding of the mounting plate 301 and the mounting frame 1. By adjusting the operation of the cylinder 306, the mounting plate 301 can slide to a specified position, which facilitates the closing of the cover plate 302 and pushes it to make the cover plate 302 close tightly. After the cover plate 302 is opened, it can slide to a certain position, which facilitates the temporary placement of the cover plate 302 on top of another cover plate 302.
