Description

Technical Field

[0001] This utility model relates to the field of lithium-ion batteries, and in particular to a laser cutting dust removal device. Background Technology

[0002] In the production process of lithium-ion batteries, the forming of the tabs is a crucial step. Typically, tabs are formed by using a laser cutting device to cut the positive and negative electrode rolls into the required tab shape. However, the laser cutting process generates a large amount of cutting dust at the cutting edges. This dust not only adheres to the waste tab material after cutting but also sticks to the conveyor belt, making it difficult to clean.

[0003] In existing technologies, brushes are typically used to clean dust from conveyor belts. However, this cleaning method has several shortcomings:

[0004] Inappropriate brush installation location: Brushes are generally designed on the inside of the conveyor belt, which makes them difficult to remove and clean during use, increasing maintenance costs.

[0005] Limited cleaning effectiveness: The brush can only perform simple sweeping of dust on the surface of the conveyor belt, but it cannot effectively remove dust adhering to the conveyor belt rollers. This leads to the continuous accumulation of dust on the conveyor belt and rollers.

[0006] Dust dispersion issue: Accumulated dust can easily disperse into the laser cutting cavity during the conveying process, causing the dust concentration inside the cavity to exceed the standard. This not only affects the precision and quality of laser cutting, but may also pose potential hazards to the normal operation of the equipment and the health of the operators.

[0007] Therefore, existing conveyor belt cleaning technologies are significantly inadequate in terms of dust removal efficiency, ease of maintenance, and dust control. There is an urgent need for a new type of dust removal device that can effectively remove dust from conveyor belts and rollers and prevent dust from scattering. Utility Model Content

[0008] The purpose of this utility model is to provide a laser cutting dust removal device, which removes dust from the inside of the conveyor belt (on the rollers) by a scraping mechanism, removes dust from the outside of the conveyor belt by a brush, and combines the negative pressure adsorption of the suction pipe to form a complete dust removal system, which significantly improves the dust removal effect and effectively avoids the problems of dust accumulation and excessive dust in the cavity.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] This utility model discloses a laser cutting dust removal device, including a conveyor belt for transporting waste, a brush disposed on the bearing end face of the conveyor belt, and a scraping mechanism disposed on the non-bearing end face of the conveyor belt; the inner side of the conveyor belt is provided with rollers, and the scraping mechanism includes a scraper for scraping off the dust adsorbed on the rollers.

[0011] As a further embodiment of this utility model, the scraping mechanism also includes a mounting plate for fixing the scraper and an ash hopper located at the bottom of the mounting plate.

[0012] As a further embodiment of this invention, the scraping mechanism also includes a suction pipe connected to the ash hopper.

[0013] As a further embodiment of this utility model: the scraper has an oblong hole, and the scraper is connected to the mounting plate by a fastener passing through the oblong hole.

[0014] As a further embodiment of this utility model, the conveyor belt is provided with a negative pressure mechanism.

[0015] As a further embodiment of this utility model, it also includes side plates installed on both sides of the conveyor belt, with both ends of the mounting plate connected to the side plates respectively.

[0016] As a further embodiment of this utility model, the brush is a rolling brush.

[0017] As a further embodiment of this invention, the conveyor belt is provided with evenly distributed adsorption holes.

[0018] As a further embodiment of this invention, the conveyor belt is equipped with a drive wheel.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention employs a scraping mechanism in conjunction with rollers to effectively scrape dust from the roller surface inside the conveyor belt. The dust is then promptly sucked away by a dust hopper and suction pipe, effectively preventing dust from scattering within the laser cutting cavity and maintaining a clean environment. Dust inside the conveyor belt can be removed without disassembly. Simultaneously, dust on the outside of the conveyor belt is swept away by a brush, ensuring rapid removal and collection of dust and preventing secondary dispersion.

[0021] The scraper mounting plate has a waist hole, which can adjust the distance between the scraper and the roller to further optimize the dust removal effect, ensure that the scraper and the roller surface are in close contact, and improve the dust removal efficiency.

[0028] Please see Figure 1-2 A laser cutting dust removal device includes a conveyor belt 1 for transporting waste material, a brush 2 disposed on the bearing end face of the conveyor belt 1, and a scraping mechanism 4 disposed on the non-bearing end face of the conveyor belt 1. Rollers 3 are provided inside the conveyor belt 1, and the scraping mechanism 4 includes a scraper 41 for scraping dust adsorbed on the rollers 3. The laser cutting machine is installed at the upper right corner of the conveyor belt 1, near the rollers 3. Waste material after the laser cutting is carried onto the conveyor belt 1. Multiple adsorption holes 11 are evenly distributed on the conveyor belt 1, and the waste material is adsorbed onto the conveyor belt 1 for transport by negative pressure adsorption. The dust generated during cutting enters the interior of the conveyor belt 1 through the adsorption holes 11, mainly accumulating on the rollers 3 near the laser cutting machine. The rollers 3 rotate with the conveyor belt 1, and the dust adsorbed on the surface of the rollers 3 is scraped off by the close contact between the scraper 41 and the rollers 3. Dust on the outside of the conveyor belt 1 is removed by the brush 2. By combining the inner and outer workings of the scraping mechanism 4 and the brush 2, dust on both ends of the conveyor belt 1 is effectively removed, preventing dust levels from exceeding the standard.

[0029] Furthermore, the scraping mechanism 4 also includes a mounting plate 42 for fixing the scraper 41 and a dust hopper 43 located at the bottom of the mounting plate 42. The scraped dust falls and is collected in the dust hopper 43 for subsequent cleaning.

[0030] Furthermore, the scraping mechanism 4 also includes a suction pipe 44 connected to the dust hopper 43. The other end of the suction pipe 44 is connected to a negative pressure machine to suck away the dust in the dust hopper 43, effectively removing dust without disassembling the inside of the conveyor belt. In other embodiments, the side plate 5 has a mounting hole for the suction pipe 44 to pass through, and an independent suction mechanism is provided outside the conveyor belt 1. This independent suction mechanism sucks out and collects the dust from the suction pipe 44.

[0031] Please continue reading. Figure 3 The scraper 41 has an oblong hole 411, and the scraper 41 and the mounting plate 42 are connected by fasteners that pass through the oblong hole 411. By adjusting the position of the fastener in the oblong hole 411, the distance between the scraper 41 and the roller 3 is adjusted, further optimizing the dust removal effect, ensuring that the scraper 41 and the roller 3 surfaces are in close contact, and improving the dust removal efficiency.

[0032] Furthermore, the conveyor belt 1 is equipped with a negative pressure mechanism, which generates negative pressure to adsorb the electrode waste onto the surface of the conveyor belt 1, and connects to the dust suction pipe 44 to generate suction to remove the dust from the ash hopper 43.

[0033] Furthermore, it also includes side plates 5 installed on both sides of the conveyor belt 1, with the two ends of the mounting plate 42 connected to the side plates 5 respectively, so that the scraper 41 is fixed inside the conveyor belt 1.

[0034] Furthermore, brush 2 is a rolling brush that is passively rolled by the rotation of conveyor belt 1 to remove dust from the outside of conveyor belt 1.

[0035] Furthermore, the conveyor belt 1 is equipped with a drive wheel 6 inside, which contacts the conveyor belt 1 and drives the conveyor belt 1 to rotate through friction.

[0036] In use, after the laser cutting machine cuts the electrode tabs into shape, the waste material is conveyed to the conveyor belt 1 and adsorbed. The dust generated during cutting enters the interior of the conveyor belt 1 through the adsorption holes 11, mainly accumulating on the rollers 3 near the cutting machine. The rollers 3 rotate under the drive of the conveyor belt 1, and the scraper 41 scrapes the dust off the rollers 3. The dust falls into the dust hopper 43 below and is then sucked away by the suction pipe 44. At the same time, the brush 2 sweeps and collects the dust on the outside of the conveyor belt 1.

[0037] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0038] Therefore, the above description is only a preferred embodiment of this application and is not intended to limit the scope of this application; that is, all equivalent modifications made in accordance with the scope of the claims of this application shall be within the protection scope of the claims of this application.
