[0036] In this embodiment, the first support plate 10 receives the battery cell a from the blanking assembly through the bearing surface 101. The first support plate 10 can move close to the second support plate 11 and clamp the battery cell a together with the second support plate 11 to prevent the battery cell a from being loose or misaligned after lamination. At the same time, the second support plate 11 rotates together with the first support plate 10 to place the battery cell a located on the bearing surface 101 on the second support plate 11.

The loading component 22 includes a clamping mechanism 221 and a pressing member 222. The clamping mechanism 221 is used to clamp the second pallet 11, and the pressing member 222 is used to press the battery cell a onto the second pallet 11. The hot pressing component 23 is used to receive the second pallet 11 and the battery cell a loaded by the loading component 22, and hot press the battery cell a. In this way, the battery cell a is pressed onto the second pallet 11 by the pressing member 222 of the loading component 22, and when the clamping mechanism 221 of the loading component 22 clamps the second pallet 11 and loads the second pallet 11 to the hot pressing component 23 for hot pressing, it can prevent the battery cell a from being loose or misaligned after lamination, thereby improving the quality of the battery cell a after hot pressing by the hot pressing component 23.

On the other hand, the first extension part 11b and the second extension part 11c located at both ends of the main body 11a protrude from the main body 11a, that is, protrude from the battery cell a placed on the main body 11a. In this way, the two clamping mechanisms 221 are used to clamp the first extension part 11b and the second extension part 11c respectively, and the loading assembly 22 keeps the balance when loading the second support plate 11 and the battery cell a to the hot pressing assembly 23, so as to avoid the second support plate 11 from tilting and causing the battery cell a on the second support plate 11 to become loose or misplaced, and at the same time, it can avoid the unloading assembly 21 from interfering with the battery cell a.

[0048] Exemplarily, the pressing member 222 is rotatable, and the pressing member 222 can rotate around the first axis α to press the battery cell a against the second pallet 11, and the extension direction of the first axis α is the same as the width direction x of the second pallet 11.
