Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing equipment technology, and in particular to a lithium battery cap packaging machine. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental controls. Therefore, lithium-ion batteries were not widely used for a long time. With the development of science and technology, lithium-ion batteries have now become mainstream. Lithium-ion batteries can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. Currently, lithium-ion battery capping machines are commonly used to seal the batteries. When sealing large quantities of lithium-ion batteries, workers need to continuously rotate a lead screw to limit the battery's position, making the capping process cumbersome, labor-intensive, and inefficient. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a lithium battery cap packaging machine.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lithium battery cap packaging machine includes a mounting frame, hydraulic cylinders, an upper mounting plate, and a pressure block. Hydraulic cylinders are vertically fixed to the left and right ends of the top of the mounting frame. An upper mounting plate is fixed to the bottom of the push rods at the output ends of the two hydraulic cylinders. A pressure block is fixed to the bottom of the upper mounting plate. Electric push rods are fixed to the left and right ends of the lower interior of the mounting frame. A bottom mounting plate is fixed to the bottom of the push rods at the output ends of the two electric push rods. A pressure rod is vertically fixed to the upper surface of the bottom mounting plate. A fixed cylinder is fixed to the lower interior of the mounting frame. An outer frame is fixed to the outer wall of the fixed cylinder. A mounting frame is embedded inside the outer frame. Anti-slip wheels are rotatably connected to the end of the mounting frame near the middle of the fixed cylinder. Limit blocks are fixed to the outer walls of the anti-slip wheels. Return springs are fixedly connected to the end of the mounting frame away from the middle of the fixed cylinder.

[0006] Preferably, the middle vertical opening of the fixed cylinder is provided with a placement groove, and the middle of the pressure block and the placement groove in the middle of the fixed cylinder are both on the same vertical horizontal plane.

[0007] Preferably, the top of the pressure rod is embedded in the lower part of the inside of the fixed cylinder, and the top of the pressure rod and the bottom of the placement groove are on the same horizontal plane. The pressure rod moves vertically up and down in the placement groove of the fixed cylinder.

[0008] Preferably, the mounting bracket slides horizontally within the outer frame, and the return spring is fixedly connected between the inner wall of the outer frame and the outer wall of the mounting bracket.

[0009] Preferably, the anti-slip wheel at one end of the mounting bracket is embedded inside the fixed cylinder, and the limiting block is fixed in a circular shape to the outer wall of the anti-slip wheel. The limiting block is made of rubber material.

[0010] Preferably, the outer wall of the fixed cylinder is provided with 6 outer frames at equal intervals, and the anti-slip wheels in the outer frames are arranged in a ring around the middle of the fixed cylinder.

[0011] When the lithium battery is placed in the fixed cylinder, it is in pre-contact with the anti-slip wheels, which push the anti-slip wheels and mounting brackets to move into the outer frame, compressing the return spring. The subsequent return spring generates a rebound force, pushing the mounting bracket and the anti-slip wheels on the mounting bracket to press tightly against the outer wall of the lithium battery. This achieves limited fixation for lithium batteries of various sizes, making it more applicable. After the lithium battery cap is sealed, the hydraulic cylinder pulls the pressure block upward through the upper mounting plate, and then the electric push rod pulls the bottom mounting plate upward, so that the pressure rod of the bottom mounting plate is embedded from bottom to top into the placement groove of the fixed cylinder, pushing the lithium battery out of the fixed cylinder. This allows for quick replacement of the sealed lithium battery, effectively improving the sealing efficiency of the lithium battery cap and making it more convenient to use.

[0018] Example 1, referring to Figure 1-4A lithium battery cap packaging machine includes a mounting frame 1, hydraulic cylinders 2, an upper mounting plate 3, and a pressure block 301. Hydraulic cylinders 2 are vertically fixed to the left and right ends of the top of the mounting frame 1. The upper mounting plate 3 is fixed to the bottom of the push rods at the output ends of the two hydraulic cylinders 2. A pressure block 301 is fixed to the bottom of the upper mounting plate 3. Electric push rods 4 are fixed to the left and right ends of the lower interior of the mounting frame 1. A bottom mounting plate 401 is fixed to the bottom of the push rods at the output ends of the two electric push rods 4. A pressure rod 402 is vertically fixed to the upper surface of the bottom mounting plate 401. A fixed cylinder 5 is fixed to the lower interior of the mounting frame 1. An outer frame 501 is fixed to the outer wall of the fixed cylinder 5. A mounting frame 502 is embedded inside the outer frame 501. Anti-slip wheels 503 are rotatably connected to the end of the mounting frame 502 near the middle of the fixed cylinder 5. Limit blocks 504 are fixed to the outer wall of the anti-slip wheels 503. Return springs 505 are fixedly connected to the end of the mounting frame 502 away from the middle of the fixed cylinder 5.

[0019] The middle vertical opening of the fixed cylinder 5 is provided with a placement groove, and the middle part of the pressure block 301 and the placement groove in the middle part of the fixed cylinder 5 are both on the same vertical horizontal plane.

[0020] When the lithium battery is placed in the fixed cylinder 3, the hydraulic cylinder 2 pushes the upper mounting plate 3 to move down, causing the pressure block 301 on the upper mounting plate 3 to move down and seal the cap on the lithium battery.

[0021] The top of the pressure rod 402 is embedded in the lower part of the inside of the fixed cylinder 5. The top of the pressure rod 402 and the bottom of the placement groove are on the same horizontal plane. The pressure rod 402 moves up and down vertically in the placement groove of the fixed cylinder 5.

[0022] After the lithium battery cap is sealed, the hydraulic cylinder 2 pulls the pressure block 301 upward through the upper mounting plate 3, and then the electric push rod 4 pulls the bottom mounting plate 401 upward, so that the pressure rod 402 of the bottom mounting plate 401 is embedded in the placement groove of the fixed cylinder 3 from bottom to top, pushing out the lithium battery in the fixed cylinder 3, realizing the quick replacement of the sealed lithium battery, effectively improving the sealing efficiency of the lithium battery cap and making it more convenient to use.

[0023] Example 2 differs from Example 1 in that, in this example, the mounting bracket 502 slides horizontally within the outer frame 501, and the return spring 505 is fixedly connected between the inner wall of the outer frame 501 and the outer wall of the mounting bracket 502.

[0024] The anti-slip wheel 503 at one end of the mounting bracket 502 is embedded inside the fixed cylinder 5, and the limiting block 504 is fixed in a ring shape on the outer wall of the anti-slip wheel 503. The limiting block 504 is made of rubber material.

[0025] When the lithium battery is placed in the fixed cylinder 3, the lithium battery is in contact with the anti-slip wheel 503 in advance, which pushes the anti-slip wheel 503 and the mounting bracket 502 to move into the outer frame 501, compressing the return spring 505. Subsequently, the return spring 505 generates a rebound force to push the mounting bracket 502 and the anti-slip wheel 503 on the mounting bracket 502 to stick tightly to the outer wall of the lithium battery, thereby limiting and fixing lithium batteries of various sizes, and making it more applicable.

[0026] The outer wall of the fixed cylinder 5 is provided with 6 outer frames 501 at equal intervals, and the anti-slip wheels 503 in the outer frames 501 are arranged in a ring around the middle of the fixed cylinder 5.

[0027] Multiple anti-slip wheels 503 can provide multiple limiting and fixing for the lithium battery;

[0028] When the lithium battery is embedded in the fixed cylinder 5, the anti-slip wheel 503 in the fixed cylinder 5 is in close contact with the outer wall of the lithium battery. The lithium battery will drive the anti-slip wheel 503 to rotate in the mounting bracket 502, making the lithium battery slide up and down more smoothly in the fixed cylinder 5.

[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.
