Description

Technical Field

[0001] The present invention relates to the technical field of hot presses, and in particular to a hot press for hot pressing of roll core batteries. Background Art

[0002] During the production process of the roll-type battery, hot pressing is required. However, since the hot pressing process takes a certain amount of time, in previous automated equipment, the robot needs to wait for the hot pressing machine to complete the hot pressing before taking out the battery and putting in a new battery for hot pressing. This will result in a waste of time and low work efficiency. Moreover, after the hot pressing mechanism has completed the hot pressing of the battery, the hot pressing plate will continue to hot press the battery for a long time, and there will be sticky glue on the surface of the hot pressing plate. If the glue stuck to the hot pressing plate is accumulated for a long time and not handled, it will not only be difficult to clean, but will also affect the hot pressing of the battery.

The loading linear drive mechanism transports two products at a time, and the feeding robot 6 has four groups of suction cups 61, of which the two groups of suction cups 61 on the front side absorb the product from the loading placement seat 42 and place it in a group of hot pressing components 711 of the hot pressing mechanism 7 on the front side, and the two groups of suction cups 61 on the rear side absorb the product from the loading placement seat 42 and place it in a group of hot pressing components 711 of the hot pressing mechanism 7 on the rear side. Therefore, two products can be conveyed each time, and the two products can be placed on the relative positions of a hot pressing mechanism 7 The hot pressing process is carried out in a corresponding group of hot pressing components 711, and the loading linear drive mechanism continues to transport the products. When one hot pressing mechanism 7 is full of products for processing, it is transported to another hot pressing mechanism 7 for hot pressing processing through the feeding robot 6. In this way, there is no need to wait for one of the hot pressing mechanisms 7 to hot press the products. The hot-pressed products are then transported to the unloading placement seat 52 of the unloading linear drive mechanism through the feeding robot 6. The unloading linear drive mechanism drives the products to be transported to the right end, and the unloading robot 8 can be used to send the products out. A brush device 72 is also provided on the hot pressing mechanism 7. The brush device 72 is started to clean the upper hot pressing plate 713 and the lower hot pressing plate 714 on the hot pressing component 711 to prevent the sol after hot pressing from adhering to the upper hot pressing plate 713 or the lower hot pressing plate 714, thereby causing damage to subsequent products.

[0046] The above description does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
