Plate 21 is lifted, and cell substrates 21 are raised between symmetrically arranged movable plate 3, at the same time, pass through bidirectional pushing part 32
The detection assembly 4 being installed on movable plate 3 is driven, it is synchronous mobile to the center of workbench 2, make to detect the detection row in assembly 4
Air drain 41 is just located on the side that cell substrates 21 need to detect, and is formed between detection air discharge duct 41 and cell substrates 21 close
Close space, external air source is passed through gas to detection air discharge duct 41, if there are cracks for the part that is provide with of cell substrates 21, then examines
Surveying the gas that air discharge duct 41 inputs can be discharged out of crack, and the air pressure of detection air discharge duct 41 would not change, will not shadow
It rings to control assembly 8, and then would not also start cutting assembly 5 and cooling unit 6, cell substrates 21 will not then occur cutting and repair
Side processing can be rejected directly by output.
If crack is not present in the basic 21 times of edges being provide with of battery, then detecting the gas in air discharge duct 41 can constantly tire out
Product, air pressure can constantly become larger, this will make the movable lug plate 85 in control assembly 8 by effects of air pressure to link piece
84 direction is mobile, docks movable lug plate 85 with link piece 86, makes the movement in external power supply and cutting assembly 5
Motor 53 and laser cutting head 56 connect, and start mobile motor 53 and laser cutting head 56 works, simultaneously because activity connects
The movement of line piece 85 opens the second exhaust port 87 of cooling unit 6, and cooling unit 6, which also synchronizes, to work, and makes cell substrates
21 during side is cut, while being cooled down.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
