Description

Technical Field

[0001] This utility model relates to the field of laser scribing technology, specifically a thin-film laser scribing device. Background Technology

[0002] Thin-film laser scribing is a method of fine processing on thin-film materials using laser technology. It is widely used in photovoltaic cells, thin-film optoelectronic devices and other fields. This technology can achieve high-precision scribing, cutting and marking operations, and the thermal impact on the material is small during the processing, without causing physical stress or surface deformation.

[0003] In the prior art, thin film materials are often stored in a warehouse for processing before being scribed. However, the warehouse environment is not absolutely dust-free, and tiny dust particles in the air inevitably adhere to the surface of the thin film material. When scribing the thin film material, the presence of these dust particles may interfere with the precise focusing of the laser, resulting in a decrease in scribing accuracy and thus affecting the quality of the final product.

[0004] Therefore, this invention provides a thin-film laser scribing device to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This invention provides a thin-film laser scribing device, such as... Figure 1 , Figure 2 and Figure 3 As shown, the scribing device includes a base plate 1, a slide plate 9 fixedly mounted on the base plate 1, a dust suction mechanism disposed on the base plate 1 for removing dust from the film material, and a scribing mechanism disposed on the base plate 1 for scribing the film material.

[0026] The vacuuming mechanism includes a vacuum hood 8 mounted on the base plate 1, a collection box 4 fixedly mounted on the base plate 1, a collection container 5 movably mounted inside the collection box 4, a vacuum cleaner 6 fixedly mounted on the top of the collection box 4, a vacuum pipe 7 fixedly mounted on the vacuum cleaner 6, and a vacuum hood 8 fixedly mounted on the end of the vacuum pipe 7 away from the vacuum cleaner 6.

[0027] After the film material is placed on the device, it will first pass through the bottom of the dust hood 8 to clean the dust on the surface of the film material. Only after this process will the device begin to scratch the film material. The vacuum cleaner 6 is then activated. The vacuum cleaner 6 is connected to the dust hood 8 through the suction pipe 7. When the film material passes through the bottom of the dust hood 8, the vacuum cleaner 6 effectively removes the dust from the film material and collects it in the collection box 5 inside the collection box 4. The collection box 5 is installed inside the collection box 4 in a pull-out manner, which makes it convenient for staff to clean the dust.

[0028] Furthermore, in order to improve the stability of the dust hood 8 during operation, such as... Figure 2 , Figure 3 and Figure 4 As shown, the vacuum cleaner 6 is connected to the inner cavity of the collection box 5, the vacuum tube 7 is connected to the inner cavity of the vacuum hood 8, and the vacuum hood 8 is fixedly connected to both sides with a locking block 18. The sliding plate 9 is fixedly connected to an installation block 17, and the installation block 17 has a slot, into which the locking block 18 is inserted.

[0029] The locking block 18 is inserted into the slot on the mounting block 17, which provides stability for the vacuum hood 8. At the same time, the locking block 18 also serves to support the vacuum hood 8, making it easy to install the vacuum hood 8.

[0030] Furthermore, in order to enable the device to scribble thin film materials, such as... Figure 1 , Figure 2 and Figure 5 As shown, the marking mechanism includes a support column 2 fixedly mounted on the base plate 1, a slide rail 3 fixedly mounted on the top of the support column 2, a first mounting bracket 19 mounted on the base plate 1, a first roller 20 rotatably mounted on the first mounting bracket 19, a first motor 22 fixedly mounted on the first mounting bracket 19, a second roller 21 fixedly mounted on the output end of the first motor 22, a second motor 23 fixedly mounted on the first mounting bracket 19, a threaded rod 24 fixedly mounted on the output end of the second motor 23, a limiting rod 25 fixedly mounted on the first mounting bracket 19, a movable plate 26 slidably mounted on the limiting rod 25, and a second mounting bracket 27 fixedly mounted on the movable plate 26.

[0031] The slide rail 3 has grooves on both sides. The side surfaces of the first roller 20 and the second roller 21 are movably connected to the inner wall of the groove. The threaded rod 24 is rotatably connected to the first mounting bracket 19. The inside of the movable plate 26 has a threaded groove that matches the threaded rod 24. The threaded rod 24 passes through the movable plate 26 through the threaded groove.

[0032] The laser scribing device is installed inside the second mounting bracket 27. When the first motor 22 is started, it drives the second roller 21 to rotate. The friction between the second roller 21 and the slide groove when it rotates allows the first mounting bracket 19 to move laterally on the slide rail 3. The first roller 20 is set to assist the first mounting bracket 19 in moving and improve the stability of the first mounting bracket 19, thereby realizing the lateral movement of the laser scribing device. The second motor 23 is started, and the second motor 23 drives the threaded rod 24 to rotate. The rotating threaded rod 24 can force the moving plate 26 to drive the second mounting bracket 27 to move longitudinally. The limit rod 25 is set to improve the stability of the moving plate 26 when it moves, thereby realizing the longitudinal movement of the laser scribing device. By controlling the bidirectional movement of the laser scribing device, the laser scribing device can scribing thin film materials according to specific needs.

[0033] It should be noted that, in order to improve the stability of the thin film material during device operation, such as Figure 1 , Figure 2 and Figure 4 As shown, a placement platform 10 is provided on the base plate 1. A placement slot is provided on the placement platform 10. A fixed frame 11 is movably connected to the top of the placement platform 10. Several insertion slots are provided on the placement platform 10. Several insertion posts 12 are fixedly connected to the side of the fixed frame 11 near the placement platform 10. The insertion posts 12 are inserted into the inside of the insertion slots.

[0034] The film material is placed in the placement slot on the placement platform 10, and then the insertion post 12 is inserted into the insertion slot. The fixing frame 11 is installed on the placement platform 10. The placement platform 10 will apply a certain amount of pressure to the film material through gravity, thereby fixing the film material and improving the stability of the film material when the subsequent device is working.

[0035] Furthermore, in order to enable the placement platform 10 to move, such as Figure 1 , Figure 2 and Figure 4 As shown, both sides of the placement platform 10 are fixedly connected to sliders 13 that insert into the inside of the slide plate 9. The inside of the slide plate 9 is provided with a sliding groove for the sliders 13 to slide. A fixing block 16 is fixedly connected to the base plate 1, and an electric push rod 15 is fixedly connected to the fixing block 16. A connecting block 14 is fixedly connected to the bottom of the placement platform 10, and the movable end of the electric push rod 15 is fixedly connected to the connecting block 14.

[0036] The placement platform 10 is designed to support the film material. The movement of the placement platform 10 is driven by the extension and retraction of the movable end of the electric push rod 15. At the same time, the slider 13 on the placement platform 10 can slide synchronously inside the slide plate 9 when the placement platform 10 moves, providing stability for the movement of the placement platform 10.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
