The specific implementation mode is as follows:

see fig. 1 to 5, a laminate polymer battery thickness check out test set has unit 1, be provided with the operation panel 2 that detects laminate polymer battery on the unit 1, slide rail 5 has on the operation panel 2, throw and expect that module 4 slides and sets up on the slide rail 5, be located it has GT to detect module 3 to throw to cooperate on the vertical face of expecting module 4, GT detects module 3 is used for detecting and places laminate polymer battery 6 on the expecting module 4.

The GT detection module 3 comprises a detection plate 39 and a lifting cylinder 37 penetrating through the periphery of the detection plate 39, the bottom of the lifting cylinder 37 is fixed on the operation table 2, an elastic floating link self-adaptive flattening assembly 38 is vertically arranged at the center of the detection plate 39, and the elastic floating link self-adaptive flattening assembly 38 is in transmission connection with the central control servo rotating shaft 32 through a pressure sensor 35.

One end of the central control servo rotating shaft 32 is connected with the servo shaft 31, a lifting cylinder 37 is arranged on the servo shaft 31, and the detecting GT group 33 is fixed at the tail end of the lifting cylinder 37. One end of the central control servo rotating shaft 32 is connected with a servo pressure cylinder 34 for providing power.

The detection board 39 has four square holes along the central axis, and the detection GT groups 33 detect the pouch batteries 6 through the square holes. The bottom of the detection plate 39 is provided with a pressing jig 36 for pressing the pouch battery 6.

Throw material module 4 and include feeding cylinder 41 and location smelting tool 42, feeding cylinder 41 fixes one side of location smelting tool 42 is used for driving location smelting tool 42 slides on slide rail 5.

The working process is as follows: the manual work is with waiting to detect that laminate polymer battery 6 puts to the product positioning jig 42 of throwing material module 4 on, fixes a position laminate polymer battery 6. The pressing equipment is started, the feeding air cylinder 41 acts to convey the positioning jig 42 and the soft package battery 6 which is positioned to the GT detection module 3 detection area, and the servo pressure cylinder 34 acts to push the pressing jig 36 to press down to press and flatten the soft package battery 6.
