[0026] In order to be able to more clearly understand the technical means of the present utility model and implement it in accordance with the content of the specification, the following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0027] See the attached Figure 1-7 As shown, the laser cleaning device for lithium battery production in Embodiment 1 includes: a cleaning module for laser cleaning texturing; a Z-axis assembly 2, a Y-axis assembly 1, and an X-axis assembly 6 that can move the cleaning module in three-dimensional space.

[0028] The cleaning module can move freely in three-dimensional space through the X-axis component 6, Y-axis component 1, and Z-axis component 2, thereby adjusting the position of laser cleaning. Through the programming of the PLC, the X-axis component 6, Y-axis component 1, and Z-axis component 2 can drive the cleaning module to automatically adjust the position, facilitating automated processing.

[0029] The cleaning module can perform laser cleaning and texturing on the rubber-coated and film-covered areas. Laser treatment can improve processing efficiency, reduce noise, generate less dust, and have high precision, making it more suitable for fully automated processing.

[0030] Among them, the cleaning module includes: a galvanometer mechanism 5 mounted on the Z-axis component 2, a dust removal mechanism 31 provided on the galvanometer mechanism 5, and the dust removal mechanism 31 is located at the front end of the galvanometer mechanism 5; and an integrated component 4 fixed to the galvanometer mechanism 5.

[0031] The galvanometer mechanism 5 can emit laser light to perform laser cleaning on the battery rubber-coated area using the laser. The dust removal mechanism 31 can suck the gas and dust generated during the cleaning process, and then it can be discharged after treatment, thereby reducing environmental pollution. The integrated component 4 can measure the distance between the workpiece and the galvanometer mechanism 5. When the distance is appropriate, it can work normally. When the distance is too close or too far, an alarm can be issued to avoid being unable to perform the cleaning operation on the workpiece due to the distance reason.

[0032] The galvanometer mechanism 5 includes a galvanometer mounting plate 51 connected to the Z-axis component 2; a galvanometer fixing plate 52 fixed to the galvanometer mounting plate 51 and perpendicular to it; and a laser galvanometer 53 mounted on the galvanometer fixing plate 52.

[0033] The laser galvanometer 53 is a device for precisely controlling the rapid movement of the laser beam in two-dimensional space. It usually consists of two mutually perpendicular galvanometers (X-axis and Y-axis), and each galvanometer contains a mirror that can swing quickly. By changing the angle of the mirror, these galvanometers can very quickly change the direction of the laser beam, thereby forming the required scanning pattern on the workpiece; enabling the galvanometer to very quickly change the beam direction, with a response time usually in the millisecond or even microsecond level, and the galvanometer can precisely control the deflection angle of the beam, with an angular resolution that can reach the micro-radian level. In addition, the design of the galvanometer enables it to maintain high precision and high stability during long-term operation.

[0034] The galvanometer mounting plate 51 is used to connect to the Z-axis component 2, enabling the Z-axis component 2 to drive the galvanometer mounting plate 51 to move, thereby driving the laser galvanometer 53 to move through the galvanometer fixing plate 52 and realizing the movement of the laser galvanometer 53 in the Z-axis direction.

[0035] Further, the Y-axis component 1 includes: a Y-axis mounting plate 11 connected to the X-axis component 6 and arranged along the Y-axis direction; a first linear module 12 arranged along the length of the Y-axis mounting plate 11; and a sliding group 13 slidably arranged on the Y-axis mounting plate 11 through a track, and the sliding group 13 is used to connect the Z-axis component 2.

[0036] The Y-axis mounting plate 11 can be connected to the X-axis component 6, so that the X-axis component 6 can drive the Y-axis component 1 to move. When the first linear module 12 works, it can drive the Z-axis component 2 to move, realizing the movement of the cleaning module in the Y-axis direction, and the sliding group 13 is used to support and assist the movement of the Z-axis component 2.

[0037] Further, the Z-axis component 2 includes a Z-axis connecting plate 21 for connecting with the Y-axis component 1; a Z-axis mounting plate 22 fixedly connected to the Z-axis connecting plate 21, and the Z-axis mounting plate 22 is arranged vertically; and a second linear module 24 arranged along the length of the Z-axis mounting plate, and a transmission part 25 fixedly connected to the galvanometer mounting plate 51 is arranged on the second linear module 24.

[0038] The Z-axis connecting plate 21 can be connected to the Y-axis component 1, and the Z-axis connecting plate 21 can be moved through the Y-axis component 1. Since the Z-axis connecting plate 21 is the base plate of the Z-axis component 2, the movement of the Z-axis component 2 is realized. When the second linear module 24 works, it can drive the transmission part 25 to move, and the transmission part 25 can drive the galvanometer mounting plate 51 to move, realizing the Z-axis direction adjustment of the galvanometer mechanism 5.

[0039] Further, a mounting track 26 is arranged along the length of the Z-axis mounting plate 22, and a sliding part 27 for fixedly connecting the galvanometer mounting plate 51 is slidably connected to the mounting track 26.

[0040] The cleaning module can be supported by the mounting track 26 and the sliding part 27, and the stability during its movement can be increased, making the cleaning range highly accurate.

[0041] Further, the X component is composed of a linear lead screw, a lead screw sleeve and a sliding part, and the sliding part is used to connect the Y-axis component 1.

[0042] When the linear lead screw rotates, the lead screw sleeve can move along the X-axis direction. The sliding part is fixedly connected to the lead screw sleeve, so that the sliding part can drive the Y-axis component 1 to move.

[0043] Further, the dust removal mechanism 31 includes: a dust removal duct 3; a connecting sheet metal 32 fixed to the dust removal duct 3; and a fixing sheet metal 33 for connecting to the galvanometer fixing plate 52, and the fixing sheet metal 33 is fixedly connected to the connecting sheet metal 32.

[0044] Inside the dust removal duct 3, a blower is installed, which can generate negative pressure. Thus, the negative pressure can be used to suck the dust generated during the laser cleaning process. The fixed sheet metal 33 and the connecting sheet metal 32 are used to fix the dust removal duct 3.

[0045] Furthermore, the dust removal duct 3 consists of a dust exhaust duct and a dust suction port. The dust suction part of the dust suction port faces the output end of the laser galvanometer 53.

[0046] When installed, the blower can be installed in the dust exhaust duct or the dust suction port as needed, and then the negative pressure at the dust suction port is used to suck the dust.

[0047] Furthermore, the integrated component 4 includes: an air knife mounting sheet metal 41; the air knife mounting sheet metal 41 is fixed on the galvanometer fixing plate 52; a super air knife 42 provided on the air knife mounting sheet metal 41; and a ranging sensor 43 provided on the air knife mounting sheet metal 41 and located below the super air knife 42.

[0048] The super air knife 42 can be paired with the dust removal duct 3 to achieve the dust removal work of laser cleaning, and the super air knife 42 can be used for drying during the film covering process, reducing the solidification time and improving the work efficiency. The ranging sensor 43 can automatically start the super air knife 42 or other linkage devices when the distance is appropriate, facilitating the fully automatic cleaning function.

[0049] Furthermore, a Z-axis auxiliary plate 23 is vertically connected to the Z-axis mounting plate 22. The Z-axis auxiliary plate 23 is connected to the sliding group 13. A triangular reinforcing rib 28 for fixedly connecting with the Z-axis mounting plate is provided on the Z-axis connecting plate 21.

[0050] The connection strength of the Z-axis component 2 can be increased through the triangular reinforcing rib 28, avoiding the situation of unstable structure caused by long-term rapid start and stop. The Z-axis auxiliary plate 23 can move smoothly on the Y-axis.

[0051] Furthermore, a reinforcing rib 54 for supporting the galvanometer fixing plate 52 is provided on the galvanometer mounting plate 51, and at least two such reinforcing ribs 54 are provided.

[0052] The reinforcing rib 54 can increase the connection strength between the galvanometer mounting plate 51 and the galvanometer fixing plate 52, increasing the stability.

[0053] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
