Description

Technical Field

[0001] This invention relates to the field of laser processing equipment technology, specifically a laser cleaning machine for removing the blue film from lithium batteries. Background Technology

[0002] Lithium-ion batteries are a type of high-performance battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. They are widely used in new energy vehicles, aerospace, and mobile devices due to their high energy density, low self-discharge rate, and long lifespan. In the production of pouch lithium-ion batteries, one process is applying a blue film. The purpose of this film is to encase the entire pouch lithium-ion battery cell, making it a unified whole and better protecting it during transportation and distribution, achieving dust and water resistance. However, when further processing is required, the blue film needs to be removed. Currently, this is done manually. However, during the direct removal process, the adhesive on the blue film adheres to the surface of the lithium-ion battery, requiring subsequent manual removal of the adhesive. This results in low overall production output for the film removal process and increased labor costs. Summary of the Invention

[0003] The purpose of this invention is to provide a laser cleaning machine for degumming the blue film of lithium batteries, so as to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, the present invention provides the following technical solution:

[0005] A laser cleaning machine for removing blue film from lithium batteries includes a frame. A conveyor belt is installed at the front end of the frame, and a first robotic arm is installed above the conveyor belt. A transport mechanism, a rotary support mechanism, and a laser processing mechanism are installed on the frame. The transport mechanism is slidably mounted on the frame. A first X-axis drive component is installed on the frame to drive the transport mechanism to move back and forth. The first X-axis drive component consists of two sets of identical linear slide modules, which are installed parallel to each other on the frame along the X-axis. The rotary support mechanism is located at the rear end of the frame, and the laser processing mechanism is located above the rotary support mechanism for laser irradiation processing of the lithium batteries on the rotary support mechanism.

[0006] The conveying mechanism includes a sliding plate, a top plate mounted above the sliding plate, and a support plate rotatably mounted above the top plate. First Z-axis cylinders are installed at the left and right ends of the sliding plate and are driven by the top plate. A first motor is installed below the top plate and is driven by the support plate. The support plate has a recessed placement groove. Clearance holes are provided on the left and right sides of the support plate, penetrating both the upper and lower ends of the support plate. The clearance holes are rectangular. At least two guide rods are provided at the front and rear ends below the top plate, with the tops of the guide rods fixedly connected to the top plate.

[0007] The rotary support mechanism includes a left rotary support assembly and a right rotary support assembly, with two sets of linear slide modules located between the left rotary support assembly and the right rotary support assembly. The left rotary support assembly includes a first fixed seat and a first support platform mounted above the first fixed seat. The first fixed seat is fixedly mounted on the frame. The first support platform includes a first rotating seat and a first push rod. One end of the first push rod is rotatably connected to the first rotating seat. The first rotating seat is fixed above the first fixed seat.

[0008] The right-hand rotation support assembly includes a second fixed base, a first Y-axis cylinder, a second motor, and a second support platform.

The second X-axis drive unit is mounted on the mounting frame and is driven by the second Z-axis cylinder. The vacuum nozzle is driven by the second Z-axis cylinder below the second Z-axis cylinder.

[0011] The laser processing mechanism includes a laser head, and the wavelength of the laser beam irradiated by the laser head is 1000nm-1300nm.

[0012] Compared with the prior art, the laser cleaning machine for degumming blue film on lithium batteries disclosed in this application has a compact structure and uses a laser beam to separate the adhesive on the blue film from the end face of the lithium battery. The laser beam fully irradiates the six end faces of the lithium battery to remove the adhesive, allowing the blue film to be easily torn off the lithium battery and ensuring that there is no adhesive residue on the end face of the lithium battery.

In this application, a wavelength of 1064nm is used to irradiate the blue film of the lithium battery. Through the blue film, the adhesive surface on the blue film is detached from the lithium battery body, achieving the de-adhesion cleaning operation.

[0022] The conveying mechanism 5 in this application includes a slide plate 501, a top plate 502 mounted above the slide plate 501, and a support plate 503 rotatably mounted above the top plate 502. First Z-axis cylinders 505 are respectively installed at the left and right ends of the slide plate 501 and are driven by the top plate 502. The slide plate 501, top plate 502, and support plate 503 are all rectangular structures. A first motor 506 is installed below the top plate 502 and is driven by the support plate 503. The first motor 506 is a servo motor, and it drives the support plate 503 to rotate above the top plate 502. A recessed placement groove 503-1 is provided on the support plate 503. A clearance hole 503-2 is provided on the left and right sides of the support plate 503 respectively. The clearance hole 503-2 passes through the upper and lower ends of the support plate 503. The clearance hole 503-2 has a rectangular structure, that is, the support plate 503 has an "H" shaped structure. At least two guide rods 504 are provided at the front and rear ends below the top plate 502 respectively. The top of the guide rod 504 is fixedly connected to the top plate 502. The top of the guide rod 504 passes through the slide plate 501. The stable lifting and lowering movement of the top plate 502 on the slide plate 501 is realized through the guide rod 504.

[0023] The rotary support mechanism 7 includes a left rotary support assembly 8 and a right rotary support assembly 9. Two linear slide modules are located between the left rotary support assembly 8 and the right rotary support assembly 9. The left rotary support assembly 8 includes a first fixed seat 801 and a first support platform 802 installed above the first fixed seat 801. The first fixed seat 801 is fixedly installed on the frame 1. The first support platform 802 includes a first rotating seat 802-1 and a first push rod 802-2. One end of the first push rod 802-2 is rotatably connected to the first rotating seat 802-1. The first rotating seat 802-1 is fixed above the first fixed seat 801.

[0024] The right rotation support assembly 9 includes a second fixed base 901, a first Y-axis cylinder 902, a second motor 903, and a second support platform 904. The second support platform 904 is slidably connected to the second fixed base 901. The first Y-axis cylinder 902 is mounted on the second fixed base 901 and drivenly connected to the second support platform 904. The second support platform 904 includes a second rotating base 904-1 and a second push rod 904-2. The second motor 903 is mounted on the second rotating base 904-1 and drivenly connected to the second push rod 904-2.

[0025] A first pressure plate 802-3 is mounted on the first push rod 802-2 towards the second push rod 904-2, and a second pressure plate 904-3 is mounted on the second push rod 904-2. Both the first pressure plate 802-3 and the second pressure plate 904-3 are made of plastic. The contact surfaces of the first pressure plate 802-3 and the second pressure plate 904-3 with the lithium battery have a comb-like structure. The plastic material of the first pressure plate 802-3 and the second pressure plate 904-3 can prevent excessive force from damaging the lithium battery. When clamping the lithium battery, the first push rod 802-2 and the second push rod 904-2 clamp the two sides of the lithium battery on the support plate 503 through the clearance hole 503-2. After being clamped, the second push rod 904-2, driven by the second motor 903, can drive the lithium battery and the first push rod 802-2 to rotate, so that the laser beam can irradiate multiple end faces of the lithium battery.

[0026] Workflow: The lithium battery is transported from the conveyor belt 2 by the first robotic arm 3 to the placement slot 503-1 of the support plate 503 on the transport mechanism 5. The support plate 503 is moved along the first driving component to the area below the laser processing mechanism 4. The first Z-axis cylinder 505 on the transport mechanism 5 drives the support plate 503 to rise upwards, and the second push rod 904-2 moves towards the transport mechanism 5, squeezing the lithium battery between the first pressure plate 802-3 and the second pressure plate 904-3. The laser beam on the laser processing mechanism 4 irradiates the blue film on the lithium battery. At the same time, the second push rod 904-2 rotates under the drive of the second motor 903, thereby driving the first push rod 802- 2. The lithium battery rotates synchronously, and the four end faces of the lithium battery are irradiated with laser. After the laser irradiation of the four end faces is completed, the first Z-axis cylinder 505 on the conveying mechanism 5 drives the support plate 503 to move upward to lift the lithium battery. The first motor 506 drives the support plate 503 to rotate 90 degrees. Then, the lithium battery is clamped by the first pressure plate 802-3 and the second pressure plate 904-3 to perform laser irradiation processing on the other two end faces of the lithium battery. After completing the processing of the six end faces of the lithium battery, it is transported to one side of the conveyor belt 2 by the conveying mechanism 5. Then, it is transported to the subsequent processing station by the first robot arm 3. This cycle is repeated.

[0027] Compared with the prior art, the laser cleaning machine for degumming blue film on lithium batteries disclosed in this application has a compact structure and uses a laser beam to separate the adhesive on the blue film from the end face of the lithium battery. The laser beam fully irradiates the six end faces of the lithium battery to remove the adhesive, allowing the blue film to be easily torn off the lithium battery and ensuring that there is no adhesive residue on the end face of the lithium battery. This effectively improves the efficiency and quality of degumming.
