Technical Field

[0001] This application relates to the technical field of battery production, and more specifically, to a cleaning device. Background Art

[0002] A screen printing device is a commonly used printing device. It controls a squeegee in contact with a screen plate to move along the screen plate, so that the printing material on the screen plate passes through the mesh holes on the screen plate and is printed onto a workpiece located below the screen plate. After the printing of the workpiece is completed, the squeegee is then controlled to rise and separate from the screen plate.

[0003] To ensure printing quality, it is necessary to regularly clean the printing material or other contaminants remaining on the screen plate and in the mesh holes. The existing cleaning devices cannot perform automatic cleaning of the screen plate. Therefore, manual cleaning of the screen plate is required, and the manual cleaning method is inefficient. Summary of the Utility Model

[0044] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] The present application provides a cleaning device for cleaning a stencil, which can achieve automatic cleaning of the stencil, thereby improving the cleaning efficiency of the stencil.

[0046] As Figure 1 shown, the cleaning device in the embodiment of the present application includes a frame 1, a driving part, and a wiping member 2. The stencil 100 to be cleaned is horizontally placed on the frame 1. Of course, the stencil 100 can also be vertically or obliquely placed on the frame 1.

[0047] The driving part is arranged on the frame 1, and the wiping member 2 is connected to the moving part of the driving part. The driving part is configured to drive the wiping member 2 to move, so that after the wiping member 2 abuts against the plate surface of the stencil 100, it slides along the plate surface of the stencil 100 to wipe the residual printing materials or other contaminants on the stencil 100 and in the mesh holes of the stencil 100.

[0048] As Figure 1As shown, optionally, the driving part includes a translation driving part 3 and a lifting driving part 4, where: the translation driving part 3 is arranged on the frame 1, the lifting driving part 4 is connected to the movable part of the translation driving part 3, and the wiping part 2 is connected to the movable part of the lifting driving part 4. The lifting driving part 4 is configured to drive the wiping part 2 to lift, and the translation driving part 3 is configured to drive the wiping part to translate.

[0049] Through the combined driving of the translation driving part 3 and the lifting driving part 4, the wiping part 2 can be moved in the horizontal and vertical directions, so as to ensure that the wiping part can slide along the plate surface of the stencil 100 after abutting against the plate surface of the stencil 100, so as to wipe the stencil 100.

[0050] When the stencil 100 is Figure 1 placed horizontally on the frame 1 as shown, the lifting driving part 4 first drives the wiping part 2 to descend, so that the wiping part 2 abuts against the plate surface of the stencil 100, and then the translation driving part 3 drives the wiping part 2 to slide horizontally along the plate surface of the stencil to wipe the stencil 100.

[0051] When the stencil 100 is placed vertically on the frame 1, the horizontal driving part 3 first drives the wiping part 2 to move horizontally towards the stencil 100, so that the wiping part 2 abuts against the plate surface of the stencil 100, and then the lifting driving part 4 drives the wiping part 2 to slide vertically along the plate surface of the stencil to wipe the stencil 100.

[0052] As Figure 1 and Figure 2 shown, optionally, the translation driving part 3 includes a first guide rail 31, a first mounting bracket 32 and a translation driving member 33. Among them, the first guide rail 31 is arranged on the frame 1 in the horizontal direction, the first mounting bracket 32 is slidably connected to the first guide rail 31 and connected to the driving end of the translation driving member 33, and the translation driving member 33 is used to drive the first mounting bracket 32 to slide along the first guide rail 31. The lifting driving part 4 includes a second guide rail 41, a second mounting bracket 42 and a lifting driving member 43. Among them, the second guide rail 41 is arranged on the first mounting bracket 32 in the vertical direction, the second mounting bracket 42 is slidably connected to the second guide rail 41 and connected to the driving end of the lifting driving member 43, and the lifting driving member 43 is used to drive the second mounting bracket 42 to slide along the second guide rail 41. The wiping part 2 is installed on the second mounting bracket 42.

[0053] When the translation driving part 3 drives the first mounting bracket 32 to slide along the first guide rail 31, the wiping part 2 can be driven to translate in the horizontal direction. When the lifting driving member 43 drives the second mounting bracket 42 to slide along the second guide rail 41, the wiping part 2 can be driven to lift and lower in the vertical direction. The first guide rail 31 and the second guide rail 41 realize the guiding and limiting of the wiping part 2, preventing the wiping part 2 from deviating or shaking.

[0054] The translation drive unit 3 can adopt various existing linear drive modules that can drive the first mounting bracket 32 to slide along the first guide rail 31. For example, a synchronous belt drive module composed of a motor and a synchronous belt. The first mounting bracket 32 is fixedly connected to one side of the belt body of the synchronous belt, and the motor drives the synchronous belt to rotate, thereby driving the first mounting bracket 32 to slide along the first guide rail 31.

[0055] The lifting drive member 43 can adopt various existing linear drive modules that can drive the second mounting bracket 42 to slide along the second guide rail 41. For example, a lead screw drive module composed of a motor, a lead screw, and a nut.

[0056] As Figure 2 shown, optionally, the wiping member 2 is a brush. The brush includes a rotating shaft 21 and bristles 22 attached to the outside of the rotating shaft 21. Both ends of the rotating shaft 21 are connected to the movable part of the drive unit. The bristles 22 in the figure are simplified diagrams and are actually filamentous.

[0057] Both ends of the rotating shaft 21 can be directly fixedly connected to the movable part of the drive unit. When the brush slides along the plate surface of the screen plate 100, the bristles 22 on the rotating shaft 21 perform wiping and cleaning on the screen plate 100.

[0058] Alternatively, the rotating shaft 21 is rotatably connected to the movable part of the drive unit. Specifically, the cleaning device in the embodiment of the present application further includes a rotation drive member 5 installed on the movable part of the drive unit. The rotation drive member 5 is used to drive the rotating shaft 21 to rotate. By setting the rotation drive member 5, when the brush slides along the plate surface of the screen plate 100, the brush can rotate rapidly under the drive of the rotation drive member 5, thereby further improving the cleaning effect of the brush on the screen plate 100.

[0059] As Figure 1 shown, optionally, the cleaning device in the embodiment of the present application further includes a detection camera 6 provided on the movable part of the drive unit. The detection camera 6 is configured to detect the cleanliness of the screen plate cleaning.

[0060] By setting the detection camera 6, automatic monitoring of the cleanliness of the screen plate 100 is realized, and the drive unit can control the wiping member 2 to perform wiping operations according to the detection results of the detection camera 6. For example, when the cleanliness of the screen plate 100 reaches a predetermined standard, the drive unit controls the wiping member 2 to stop wiping. Another example is that when the detection camera 6 detects a large amount of pollutants in a certain area of the screen plate 100, the drive unit controls the wiping member 2 to directly move to this area to perform precise wiping.

[0061] As Figure 4 shown, optionally, a light source 7 is further provided on the frame 1. The light source 7 is used to provide light to the detection camera 6 to improve the detection accuracy of the detection camera 6. The light source 7 can adopt a surface light source, such as Figure 1When the middle screen plate 100 is horizontally arranged, the surface light source is horizontally arranged below the screen plate 100 to provide better illumination for the shooting of the detection camera 6.

[0062] As Figure 1 and Figure 5 shown, optionally, the cleaning device in the embodiment of the present application further includes a squeegee 8. The squeegee 8 is installed on the frame 1, and the driving part is further configured to drive the wiping member 2 to move so that the wiping member 2 contacts the squeegee 8 and passes by the squeegee 8. The squeegee 8 is used to scrape off the contaminants on the wiping member 2.

[0063] It can be seen that by setting the squeegee 8, the automatic removal of the printing materials or other contaminants accumulated on the wiping member 2 is realized, so that the wiping member 2 maintains the wiping effect.

[0064] Optionally, the cleaning device in the embodiment of the present application further includes a storage box 9. The storage box 9 is arranged on the frame 1 and below the squeegee 8. The contaminants scraped off by the squeegee 8 fall into the storage box 9 to prevent the printing materials or other contaminants from falling and polluting the machine table.

[0065] As Figure 3 and Figure 4 shown, optionally, a plurality of support blocks 10 are arranged on the frame 1, and the screen plate 100 is supported on the plurality of support blocks 10. The cleaning device in the embodiment of the present application further includes a pressing assembly 110 arranged on the frame 1 and on opposite sides of the screen plate 100. The pressing assembly 110 is used to press the screen plate 100 onto the plurality of support blocks 10.

[0066] When the screen plate 100 is placed on the plurality of support blocks 10, the pressing assemblies 110 on both sides cooperate to press and position the screen plate from both sides to prevent the screen plate 100 from shaking during the cleaning process.

[0067] Optionally, the pressing assembly 110 includes a rotary pressing cylinder 111 and a pressing block 112. Among them, the pressing block 112 is connected to the driving end of the rotary pressing cylinder 111. The rotary pressing cylinder 111 drives the pressing block 112 to lift and rotate, so as to press and release the screen plate 100.

[0068] The screen plate 100 of the present application can be used for applying glue to the solder tapes on the battery string during the production of battery wafers, that is, the screen plate 100 is installed at the glue application station, the glue is placed on the screen plate 100, and the glue is scraped out of the mesh holes of the screen plate 100 by a squeegee and applied to the solder tapes of the battery string. Or the screen plate 100 is used to apply glue to the battery wafers first, and then the solder tapes and the battery wafers are connected in series. After the screen plate 100 is used for a long time, the glue adheres to the mesh holes and easily blocks the mesh holes, affecting the glue application effect. Therefore, the cleaning device of the present application can be used to clean the screen plate.

[0069] The above has described the present application in sufficient detail with a certain degree of particularity. Those of ordinary skill in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the protection scope of the present application.
