[0002] Lithium batteries are a common small device used to provide electrical energy and are widely used in various electronic devices. Common lithium batteries require an aluminum-plastic film packaging shell with pits to wrap and seal the lithium battery cells. Therefore, the manufacturing process of lithium batteries requires a shell punching process in which the aluminum-plastic film raw material is punched into a single-piece packaging shell with pits.

In addition, when prying the product, the product appearance may be damaged to a certain extent, requiring polishing and repair, resulting in a low product shipment rate. For this reason, we provide an aluminum-plastic film stamping device for lithium battery packaging equipment. Utility Model Content

[0024] See also Figure 1-5 As shown, the utility model is an aluminum-plastic film stamping device for lithium battery packaging equipment, including a demoulding mechanism 1 and a workbench 101. The demoulding mechanism 1 is provided with a cutting mechanism 2 on the front side. A lower mold 115 is fixedly connected to the top of the workbench 101. A demoulding rod 114 is slidably connected to the interior of the lower mold 115. The bottom of the demoulding rod 114 passes through the lower mold 115 and extends to the interior of the workbench 101. A top block 113 is fixedly connected to the bottom of the demoulding rod 114. The bottom of the top block 113 contacts an extrusion block 116. The right side of the extrusion block 116 contacts a limiting rod 117. The front and back sides of the limiting rod 117 are respectively fixedly connected to the inner wall of the workbench 101. A spring 118 is fixedly connected to the right side of the extrusion block 116. The right side of the spring 118 is fixedly connected to the inner wall of the workbench 101. The front and back sides of the extrusion block 116 are fixedly connected. There is a pull rod 111, and a sliding block 112 is fixedly connected to the bottom of the pull rod 111. A sliding groove 110 is opened inside the workbench 101. When the extension plate 106 moves upward, it drives the slide rod 108 to move upward along the slide groove 107, and when the slide rod 108 moves upward, it drives the connecting rod 109 to move, and then the pull rod 111 is pulled upward by the connecting rod 109 to move to the left. When the pull rod 111 moves to the left, it will drive the extrusion block 116 to move to the left to push the top block 113 upward, and at the same time pull the spring 118. When the top block 113 moves upward, it will synchronously push the demoulding rod 114 upward to move it into the lower mold 115, and lift the stamped mold to complete rapid demoulding, so as to prevent the lower mold 115 from being tightly attached to the material due to too long time, making demoulding difficult.

[0025] The outer surface of the sliding block 112 is slidably connected to the inner wall of the sliding groove 110. The left side of the pull rod 111 is rotatably connected to the connecting rod 109. The end of the connecting rod 109 away from the pull rod 111 is rotatably connected to the sliding rod 108. A sliding groove 107 is opened inside the workbench 101.

[0026] The outer surface of the slide rod 108 is slidably connected to the inner wall of the slide groove 107, the top of the workbench 101 is fixedly connected to the top plate 102, the inside of the top plate 102 is fixedly connected to the hydraulic press 103, the bottom output end of the hydraulic press 103 is fixedly connected to the connecting rod 105, and the bottom of the connecting rod 105 is fixedly connected to the upper mold 104.

[0027] An extension plate 106 is fixedly connected to the outer surface of the connecting rod 105 , and a sliding fixed plate 122 is fixedly connected to the left bottom of the extension plate 106 . There are two fixed plates 122 in total.

[0028] A rotating shaft 121 is fixedly connected to one side of the fixing plate 122 close to each other. There are two rotating shafts 121 in total. The two rotating shafts 121 are symmetrically arranged with the extension plate 106 as the center. The outer surface of the rotating shaft 121 is rotatably connected to the connecting ring 119.

[0029] A second spring 120 is fixedly connected to the top of the connecting ring 119 , and the top of the second spring 120 is fixedly connected to the bottom of the extension plate 106 .

[0030] The cutting mechanism 2 includes a mounting groove 201 provided inside the extension plate 106, a mounting block 202 being slidably connected inside the mounting groove 201, and a cutting knife 203 being fixedly connected to the bottom of the mounting block 202. When the extension plate 106 moves downward, the cutting knife 203 is synchronously driven to move downward. After the upper mold 104 and the lower mold 115 have been in contact for a certain period of time, the cutting knife 203 will come into contact with the aluminum-plastic film and cut off the aluminum-plastic film from between the placement grooves 206, so that the aluminum-plastic film can be formed into separate sheets, which is convenient for subsequent work or packaging. At the same time, the mounting block 202 and the mounting groove 201 are detachable, and when the cutting knife 203 is damaged, it can be directly replaced.

[0031] A support leg 204 is fixedly connected to the top of the workbench 101 , a placement block 205 is fixedly connected to the top of the support leg 204 , and a placement slot 206 is provided inside the placement block 205 .

[0032] A specific application of this embodiment is as follows: the staff first places the aluminum-plastic film through the placement groove 206 onto the lower mold 115, and then starts the hydraulic press 103. The hydraulic press 103 starts to push the connecting rod 105 downward, and when the connecting rod 105 moves downward, it drives the upper mold 104 to move to stamp the aluminum-plastic film placed on the lower mold 115. When the connecting rod 105 moves downward, it will simultaneously drive the extension plate 106 to move downward, and then the extension plate 106 drives the connecting ring 119 downward to move downward, and the upper mold 104 moves downward. When the upper mold 104 is stamping, the connecting ring 119 will contact the slide bar 108 and move downward. At the same time, the connecting ring 119 will expand to both sides and squeeze the spring 2 120. After the upper mold 104 completes the stamping, the slide bar 108 will completely enter the connecting ring 119, so that the extension plate 106 drives the slide bar 108 to move upward along the slide groove 107 when moving upward. When the slide bar 108 moves upward, it drives the connecting rod 109 to move, and then the connecting rod 109 pulls the pull rod 111 upward to move to the left. When the pull rod 111 moves to the left, it will drive the extrusion block 116 to move to the left to push the top block 113 upward, and at the same time pull the spring 118. When the top block 113 moves upward, it will simultaneously push the demoulding rod 114 upward to move into the lower mold 115, and push the stamped product up to complete the rapid demoulding. After the slide bar 108 moves to the top of the slide groove 107, the slide bar 108 can no longer move, but the extension plate 106 will continue to drive the connecting ring 119 to move upward. Continuously moving the middle slide bar 108 upward will push the connecting ring 119 to both sides until the connecting ring 119 is disengaged. After disengagement, the spring 118 will rebound to reset the device, so that the demoulding rod 114 will re-enter the workbench 101. When the extension plate 106 moves downward, it will synchronously drive the cutting knife 203 to move downward. After the upper mold 104 and the lower mold 115 have been in contact for a certain period of time, the cutting knife 203 will come into contact with the aluminum-plastic film and cut the aluminum-plastic film from between the placement grooves 206, so that the aluminum-plastic film can be formed into separate sheets, which is convenient for subsequent work or packaging.
