In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The soft-package battery cell feeding and sorting equipment provided by the embodiment of the invention comprises an equipment body and a feeding trolley 100, wherein the feeding trolley 100 is butted with the equipment body, and after the butting, feeding is realized on the equipment body through the feeding trolley 100; in addition, the equipment body is equipped with tray material loading module 200, electric core and picks up module 500, electric core test module 600, electric core and selects separately module 700, unqualified electric core unloading module 800 and unloading assembly line 900.

Wherein, on battery core picking module 500 movably located battery core sorting module 700, battery core sorting module 700 can drive battery core picking module 500 and move to predetermineeing and put the position. For example, when a cell needs to be picked up from the tray loading module 200 to the cell testing module 600, the cell sorting module 700 drives the cell picking module 500 to move to the upper side of the tray loading module 200, so that the cell picking module 500 can pick up the cell to be tested downwards; for another example, when needs are transported unqualified electric core to unqualified electric core unloading module 800 on, select separately module 700 through electric core and drive electric core and pick up module 500 and move to the top of unqualified electric core unloading module 800 to power supply core picks up module 500 and places unqualified electric core downwards.

The working principle of the soft-package battery cell feeding and sorting equipment provided by the embodiment of the invention is as follows: after the loading trolley 100 transports the whole stack of cell trays filled with the cells to the tray loading module 200, the cells 123.1 in the cell trays 123.5 are transported to the cell testing module 600 through the cell sorting module 700 and the cell picking module 500 so as to be tested by the cell testing module 600 on the cells 123.1; after the test is completed, the battery cell picking module 500 and the battery cell sorting module 700 are used for transporting the battery cells 123.1 passing the test to the blanking assembly line 900 and transporting the battery cells 123.1 not passing the test to the unqualified battery cell blanking module 800.

Therefore, the soft package battery cell feeding and sorting equipment can realize the assembly line operation of battery cell 123.1 feeding, testing and sorting, and compared with a mode of more manual participation, the soft package battery cell feeding and sorting equipment provided by the embodiment of the invention can greatly reduce the labor intensity of operators, and can save resources such as manpower, field and turnover, thereby reducing the production cost.

In order to facilitate the positioning of the feeding trolley 100, the feeding trolley 100 is provided with a convex positioning block 107, correspondingly, the equipment body is provided with a concave positioning block 116 and two feeding trolley limiting plates 115, and after the feeding trolley 100 enters a space formed by the two feeding trolley limiting plates 115, the concave positioning block 116 is matched with the convex positioning block 107 to realize the positioning and the fixing of the feeding trolley 100 and the equipment body.

The feeding trolley 100 is further provided with a cell feeding belt 110, the equipment body is further provided with an equipment feeding belt 121 butted with the cell feeding belt 110, and a whole stack of cell trays filled with cells are conveyed to the equipment feeding belt 121 through the cell feeding belt 110 and then reach preset positioning positions on the tray feeding module.

The principle of the loading trolley 100 is explained in detail below.

The feeding trolley limiting plate 115 is fixed on the ground, and is roughly positioned with the outer frame 101 of the feeding trolley 100 through the pulleys on the feeding trolley limiting plate, and the convex positioning block 107 on the trolley is matched with the concave positioning block 116 of the equipment body for fine positioning. At this time, the proximity switch 114 and the proximity switch trigger 105 mutually sense, and when a signal is given to the positioning cylinder 113, the positioning cylinder 113 presses the fixed cushion block 106 after acting, so that the feeding trolley 100 is installed on the equipment body.
