[0007] Preferably, the inside of placing plate and limit board is all set with placing opening around, the middle part of pressure welding head and the placing opening of middle part of placing plate and limit board are all on the same vertical horizontal plane.

[0008] Preferably, the bottom of placing plate is close to the upper surface of bottom plate, and the bottom plate covers the bottom of the placing opening of the placing plate.

[0009] Preferably, the limiting plate moves up and down vertically outside the limiting post, and the cross-sectional area of ​​the limiting plate is the same as the cross-sectional area of ​​the middle part of the placement plate.

At this point, the hydraulic cylinder pushes the mounting plate downwards, causing the welding head below the mounting plate to press the lithium battery cap in place. The pressing effect is good. After pressing, two electric push rods pull the placement plate and limiting plate forward via the outer plate. When the bottom plate no longer supports the bottom of the placement opening in the placement plate, the pressed lithium battery quickly falls into the collection box on the worktable. Then, the electric push rods pull the placement plate and limiting plate back to their original positions via the outer plate. This allows for quick replacement of the lithium battery, resulting in high pressing efficiency and greater ease of use. Attached Figure Description

[0019] Example 1, referring to Figures 1-4An automatic positioning and pressing device for lithium battery caps includes a workbench 1 and a mounting frame 2. The mounting frame 2 is fixed to the top of the workbench 1. Hydraulic cylinders 201 are vertically fixed to the left and right ends of the top of the mounting frame 2. The bottom of the push rods at the output ends of the two hydraulic cylinders 201 is fixed to the mounting plate 202. The bottom of the mounting plate 202 is fixed to the pressure welding head 203. A placement plate 3 is embedded in the lower interior of the mounting frame 2. An outer plate 301 is fixed to the left and right ends of the placement plate 3. An electric push rod 302 is fixed to the left and right ends of the top of the mounting plate 3. Limiting posts 303 are vertically fixed to the left and right ends of the top of the placement plate 3. A limiting plate 304 is nested on the outside of the limiting posts 303. An adjusting bolt 305 is vertically embedded in the middle of the front end of the placement plate 3 and the limiting plate 304. A base plate 4 is horizontally fixed in the lower interior of the mounting frame 2.

[0020] The placement plate 3 and the limiting plate 304 both have vertical openings for placement. The middle part of the welding head 203 and the placement openings in the middle of the placement plate 3 and the limiting plate 304 are on the same vertical horizontal plane.

[0021] When the hydraulic cylinder 201 pushes the mounting plate 202 down, the welding head 203 below the mounting plate 202 moves down at the same time, which can press the lithium battery cap in the placement port of the placement plate 3 and the limiting plate 304 into place, and the pressing effect is good.

[0022] The bottom of the placement plate 3 is in close contact with the upper surface of the base plate 4, and the base plate 4 covers the bottom of the placement opening of the placement plate 3.

[0023] The top of the push rods at the output end of the two electric push rods 302 are connected to the outer plate 301. The outer plate 301, the limiting post 303, the limiting plate 304 and the adjusting bolt 305 slide back and forth on the upper surface of the base plate 4.

[0024] After the lithium battery is inserted into the placement opening of the placement plate 3 through the placement opening of the limiting plate 304, the bottom plate 4 supports the bottom of the placement opening of the placement plate 3, preventing the lithium battery from falling through the placement opening of the placement plate 3. At this time, the hydraulic cylinder 201 pushes the mounting plate 202 down, causing the welding head 203 under the mounting plate 202 to move down and press the lithium battery cap, resulting in a good pressing effect.

[0025] Example 2 differs from Example 1 in that, in this example, the limiting plate 304 moves up and down vertically outside the limiting post 303, and the cross-sectional area of ​​the limiting plate 304 is the same as the cross-sectional area of ​​the middle part of the placement plate 3.

[0026] Based on the height of the lithium battery, the adjusting bolt 305 is turned at the front end of the placement plate 3 and the limiting plate 304, so that the limiting plate 304 moves up and down outside the limiting post 303 above the placement plate 3, adjusting the distance between the limiting plate 304 and the placement plate 3, so that the lithium battery can be placed exactly between the placement opening of the limiting plate 304 and the placement plate 3, avoiding the lithium battery in the placement opening from shaking during the pressing process.

[0027] A collection frame is provided at the front end of the upper surface of the workbench 1, and the collection frame is located at the bottom front end of the base plate 4.

[0028] After the lithium battery is pressed into place, the two electric push rods 302 pull the placement plate 3 and the limiting plate 304 forward through the outer plate 301. When the bottom plate 4 no longer supports the bottom of the placement port in the placement plate 3, the pressed lithium battery quickly falls into the collection box of the workbench 1. Then, the electric push rods 302 pull the placement plate 3 and the limiting plate 304 back to their original positions through the outer plate 301. Subsequently, the lithium battery can be quickly replaced, which has high pressing efficiency and is more convenient to use.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
