[0029] In this embodiment, the gripper cylinder picks up the battery body with blue film on other conveyor lines and positions it during the oven baking and heat shrinking process. Specifically, before production, the equipment personnel first adjust the relative position size of the fixed positioning block and the left clamping block according to the customer's wrapping requirements.

[0030] This invention relates to a PET film positioning mechanism for a cylindrical battery wrapping machine.

This invention has the advantages of simple structure, accurate positioning, and prevention of displacement. Example 2

[0031] like Figure 1-4As shown, a PET film positioning mechanism for a cylindrical battery sleeve machine includes a gripper assembly 1 and a positioning assembly 5. The gripper assembly 1 consists of a gripper cylinder 11 and a set of cylinder claws 12. A left sleeve assembly 2 and a right sleeve assembly 3 are respectively arranged inside the set of cylinder claws 12. A cylindrical battery assembly 4 is gripped between the left sleeve assembly 2 and the right sleeve assembly 3. The gripper assembly 1 realizes an effective gripping and grasping operation of the cylindrical battery assembly 4. The positioning assembly 5 is installed on one of the cylinder claws 12 and consists of a positioning cylinder 51 and a moving assembly 52. ​​The positioning assembly 5 realizes a reliable and accurate positioning operation of the cylindrical battery assembly 4.

[0032] The positioning component 5 includes a positioning cylinder 51 mounted on one of the cylinder grippers 12 and a moving component 52 poweredly connected to the positioning cylinder 51.

[0033] The moving component 52 includes a U-shaped slider mounting plate 201. A set of slide blocks 202 are installed on both the front and rear sides of the slider mounting plate 201. The slide blocks 202 are slidably connected to the linear guide rails 203 arranged on the front and rear sides of the cylinder claw 12.

[0034] The slider mounting plate 201 is provided with a cylinder push plate 204 connected to the positioning cylinder 51. A buffer 205 is installed on the upper part of the cylinder push plate 204.

The movable positioning blocks 206 are connected to the cylinder push plate 204 through a set of fixing holes 207. A sponge block 208 is installed on the inner side of each movable positioning block 206.

[0035] In this embodiment, during production, the gripping cylinder moves to the station where the cylindrical battery assembly to be gripped is located. Using the gripping force of the cylinder, the battery body is lifted and removed from the conveyor line. Then, the positioning cylinder begins to position the blue film. The positioning cylinder drives the slider mounting plate to move. The slider mounting plate is equipped with a cylinder pusher plate, and movable positioning blocks are mounted on both sides of the pusher plate. Sponge blocks are mounted on the movable positioning blocks. During positioning, the sponge blocks push the blue film to the left side to contact the fixed positioning block, achieving precise positioning. Simultaneously, the cylinder pusher plate is equipped with a limit buffer, which limits the movement after positioning to prevent the positioning cylinder from moving too far and compressing or deforming the blue film. The flexibility of the sponge blocks not only achieves the positioning function but also absorbs 1mm of compression, preventing deformation of the blue film.

[0036] When the gripper cylinder moves to the oven position, after placing the cylindrical battery assembly at the workstation, first open the positioning cylinder, then open the gripper cylinder to complete the entire gripping and positioning function.

[0037] This invention relates to a PET film positioning mechanism for a cylindrical battery wrapping machine. It allows the PET heat-shrink film to be precisely positioned on the battery, resulting in a more accurate wrapping size. In use, based on existing positioning defects, the positioning component 5 of this invention is set on the gripping and handling robotic arm. After gripping, the PET film is positioned, reducing the displacement of the PET film during gripping or handling. This invention has the advantages of simple structure, accurate positioning, and prevention of displacement.
