[0008] As a preferred solution of the utility model, a connecting block is slidably provided on the guide rail, and the connecting block is fixedly connected to the movable end plate. Since the movable end plate is not directly slidably provided on the guide rail, it is necessary to firstly slide the connecting block on the guide rail, and then fix the movable end plate to the connecting block, so as to enable the movable end plate to slide along the guide rail direction.

[0009] As a preferred solution of the utility model, a mounting seat is provided on the base plate, and the screw rod is rotatably connected to the mounting seat.

After the battery cell to be tested is coated with glue, it is placed between the fixed end plate and the movable end plate. The screw rod is rotated to maintain the pressure. The pressure applied can be accurately known through the pressure sensor display. The most suitable glue dosage and pressure holding pressure standard can be determined through the experimental results.

[0018] 2. The glue coating verification tooling is configured by setting the limit plate on the bottom plate and then setting a guide rail on the limit plate, and sliding the movable end plate on the limit plate through the guide rail.
