Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to a laser processing dust removal device and a laser processing dust removal system. Background Art

[0002] The dust removal system of general laser processing equipment is designed as an integral exhaust structure with a large cavity. In order to meet environmental protection requirements, a high-power dust collector is required, which occupies a large area and has complex pipeline installation, which is prone to leaks and air leaks, resulting in poor exhaust effects. In actual work, the smoke and dust generated in the equipment cannot be exhausted in time, resulting in many small-sized particles and foreign matter on the surface of the product, which seriously affects product performance and further processing of subsequent processes. Especially for products in the high-tech field, even very small residual particles will cause serious defects.

[0003] The processing technology of perovskite photovoltaic products includes multiple laser processes such as P1, P2, P3, and P4. Products with photovoltaic building integration (BIPV) functions also require laser scribing and light transmission processes. Except for P1, which can be cleaned, other processes cannot be cleaned and can only be dusted by non-contact methods. Simple vacuuming and dust removal in laser processing equipment does not completely remove dust.

[0004] One solution is to use partitions to separate the lower part or side of the laser processing equipment workbench into several small chambers of equal geometric dimensions arranged longitudinally and the main air suction duct in the front, which is connected to the dust collector; valves are installed between each small chamber and the main air suction duct, and the machine-controlled valve controls the cylinder through the air inlet and outlet pipes; the air extraction process of the system is controlled by opening and closing the valve. This method saves space and improves the dust removal effect. However, this method is not suitable for unilateral processing only for the upper surface or only for the lower surface. In addition, due to the wide distribution of dust particle sizes generated by processing, the dust removal system cannot clean up dust in the entire particle size range, so there is always dust on the product surface that has not been completely sucked away.

[0005] Therefore, the dust removal system of the existing laser processing equipment does not remove dust thoroughly and cannot fully meet the dust removal requirements. Utility Model Content

[0006] In view of this, the utility model provides a laser processing dust removal device and a laser processing dust removal system to solve the problem that the dust removal system of the existing laser processing equipment does not remove dust thoroughly and cannot fully meet the dust removal requirements.

[0007] In a first aspect, the utility model provides a laser processing dust removal device, comprising:

[0008] A dust removal head is arranged on one side of the third direction of the transmission line;

[0009] The dust removal head includes a first tube body and a second tube body that are interconnected, the first tube body and the second tube body are connected to form a dust removal part, and a dust removal port is provided on a side of the dust removal part close to the product surface;

[0010] The first tube body is suitable for performing positive pressure blowing toward the product surface through the dust removal port to remove foreign matter from the product surface, and the second tube body is suitable for performing negative pressure suction through the dust removal port to absorb foreign matter from the product surface.

[0011] Beneficial effect: The laser processing dust removal device provided by the utility model has a dust removal head fixedly arranged on one side of the third direction of the transmission line, and the dust removal head mainly includes a first tube body, a second tube body and a dust removal part, and a dust removal port is opened on the side of the dust removal part close to the product surface; by introducing positive-pressure gas (compressed air) into the first tube body, the positive-pressure gas is blown toward the product surface through the dust removal port for positive pressure, so that foreign matter on the product surface is separated from the product surface, and at the same time, negative-pressure suction is performed on the second tube body, so that foreign matter separated from the product surface can be sucked out in time through the dust removal port within a limited space, thereby avoiding the problem of difficulty in concentrated dust extraction after the foreign matter is blown to the entire space, and realizing one-time thorough dust removal of the product.

[0012] In an optional embodiment, the negative pressure value in the second tube body is greater than the positive pressure value in the first tube body.

[0013] Beneficial effect: The negative pressure value in the second tube body is greater than the positive pressure value in the first tube body, so as to ensure that the second tube body will suck and discharge all the gas blown from the first tube body to the surface of the product to the outside of the processing cavity, and prevent the gas blown from the first tube body to the surface of the product from diffusing to the entire processing cavity.

[0014] In an optional embodiment, an angle adjustment portion is provided between the dust removal portion and the first tube body and / or the second tube body, and the angle adjustment portion is suitable for adjusting the relative angle between the first tube body and / or the second tube body and the dust removal portion.

[0017] The gap between the second side wall and the product surface is greater than or equal to the gap between the first side wall and the product surface.

[0018] Beneficial effect: The gap between the second side wall and the product surface is equal to the gap between the first side wall and the product surface, which can facilitate processing, and at the same time, a certain distance is kept between the negative pressure exhaust side and the product surface, thereby ensuring gas circulation. The gap between the second side wall and the product surface is larger than the gap between the first side wall and the product surface, so as to ensure that the negative pressure exhaust side is at a sufficient distance from the product surface, thereby ensuring gas circulation. Since positive pressure blowing can achieve an ideal dust removal effect without leaving enough distance, the positive pressure blowing side can be as close to the product surface as possible, thereby ensuring that the dust is completely separated from the product surface. At the same time, negative pressure exhaust is set at a relatively close distance to suck away the dust that has separated from the product surface as soon as possible.

[0019] In an optional embodiment, the first tube body and the second tube body are arranged in pairs; multiple pairs of the first tube body and the second tube body are arranged side by side on the dust removal head;

[0021] The dust removal head also includes a fourth tube body, which is simultaneously connected to one end of each second tube body away from the dust removal port, and the fourth tube body is suitable for connecting multiple second tube bodies in parallel.

[0022] Beneficial effect: By setting a third tube body to connect multiple first tube bodies in parallel, and by setting a fourth tube body to connect multiple second tube bodies in parallel, multiple dust removal ports are arranged side by side along the first direction. During the product conveying process, the product surface can be dusted simultaneously through the multiple dust removal ports, thereby improving the dust removal efficiency.

[0025] The air compressor is arranged at one end of the first tube body away from the dust removal port, and the air compressor is suitable for introducing positive pressure gas into the first tube body.

[0026] Beneficial effects: First, the laser processing dust removal system of the second aspect includes the laser processing dust removal device of the first aspect, and therefore, the laser processing dust removal system of the second aspect includes all the beneficial effects of the laser processing dust removal device of the first aspect. Secondly, the air compressor is connected to the end of the first tube body away from the dust removal port, so that positive pressure gas is continuously introduced into the first tube body through the air compressor, so that the positive pressure gas is blown toward the surface of the product through the dust removal port, so that foreign matter on the surface of the product is separated from the surface of the product.

[0027] In an optional embodiment, the laser processing dust removal system also includes a first filter, which is arranged at the compressed air output port of the air compressor, and the first filter is suitable for performing a first filtration on the compressed air to remove water vapor and oil contained in the compressed air.

[0046] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0047] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0048] According to an embodiment of the utility model, on the one hand, a laser processing dust removal device is provided, comprising:

[0049] The dust removal head 10 is fixedly arranged on one side of the third direction of the transmission line;

[0050] See also Figure 2 As shown, the dust removal head 10 includes a first tube body 11 and a second tube body 12 that are interconnected. The first tube body 11 and the second tube body 12 are arranged at an angle. The first tube body 11 and the second tube body 12 are connected to form a dust removal portion 13. A dust removal port 131 is provided on one side of the dust removal portion 13 close to the product surface.

[0051] The first tube body 11 is suitable for performing positive pressure blowing toward the product surface through the dust removal port 131 to remove foreign matter from the product surface, and the second tube body 12 is suitable for performing negative pressure suction through the dust removal port 131 to absorb foreign matter from the product surface.

[0052] It should be noted that the laser processing dust removal device provided by the utility model is arranged on the product transmission line after the laser process, so as to achieve thorough dust removal during the product transmission process. The laser processing dust removal device provided by the utility model can be arranged on any one side of the transmission line along the third direction, so as to be applicable to a single-sided processing process for only the upper surface or only the lower surface of the product, or can be arranged on both sides of the transmission line along the third direction, so as to be applicable to a double-sided processing process for the upper and lower surfaces of the product.

[0053] Optionally, the first tube body 11, the second tube body 12 and the dust removal part 13 can be integrally formed.

[0054] The laser processing dust removal device provided by the utility model has a dust removal head 10 fixedly arranged on one side of the third direction of the transmission line, and the dust removal head 10 mainly includes a first tube body 11, a second tube body 12 and a dust removal part 13, and a dust removal port 131 is provided on the dust removal part 13 on one side close to the product surface; by introducing positive pressure gas (compressed air) into the first tube body 11, so that the positive pressure gas is blown toward the product surface through the dust removal port 131 for positive pressure, so that foreign matter on the product surface is separated from the product surface, and at the same time, by negative pressure suction on the second tube body 12, the foreign matter separated from the product surface is timely sucked and discharged through the dust removal port 131 in a limited space, thereby avoiding the problem of difficulty in concentrated dust extraction after the foreign matter is blown to the entire space, and realizing one-time thorough dust removal of the product.

[0055] In some embodiments, the negative pressure value in the second tube 12 is greater than the positive pressure value in the first tube 11 .

[0056] It should be noted that the negative pressure value in the second tube body 12 is greater than the positive pressure value in the first tube body 11, so as to ensure that the second tube body 12 will suck and discharge all the gas blown from the first tube body 11 to the surface of the product to the outside of the processing chamber, and prevent the gas blown from the first tube body 11 to the surface of the product from diffusing to the entire processing chamber.

[0057] In some embodiments, see Figure 3 As shown, an angle adjustment portion 16 is provided between the dust removal portion 13 and the first tube body 11 and / or the second tube body 12 , and the angle adjustment portion 16 is suitable for adjusting the relative angle between the first tube body 11 and / or the second tube body 12 and the dust removal portion 13 .

[0058] Furthermore, the angle adjustment portion 16 can be a bellows structure, one end of the angle adjustment portion 16 is connected to the dust removal portion 13, and the other end is connected to the first tube body 11 and / or the second tube body 12, so that the angle change between the first tube body 11 and / or the second tube body 12 and the dust removal portion 13 can be adjusted according to the actual dust removal effect.

[0059] In this embodiment, by setting an angle adjustment part 16 between the dust removal part 13 and the first tube body 11 and / or the second tube body 12, the angle change between the first tube body 11 and / or the second tube body 12 and the dust removal part 13 can be adjusted according to the actual dust removal effect, so that the dust removal is more thorough and clean.

[0060] In some embodiments, please combine Figure 2 and Figure 3 As shown, a first side wall 132 and a second side wall 133 are formed on both sides of the dust removal port 131 in the second direction, respectively. The first side wall 132 is located on the side of the dust removal port 131 close to the first tube body 11 along the conveying direction, and the second side wall 133 is located on the side of the dust removal port 131 close to the second tube body 12 along the conveying direction;

[0061] The gap between the second side wall 133 and the product surface is greater than or equal to the gap between the first side wall 132 and the product surface.

[0062] It should be noted that the dust removal port 131 is almost in close contact with the product surface, but a clearance must be maintained between the dust removal port 131 and the product surface to ensure dust removal effect. The first side wall 132 is located on the side of the dust removal port 131 close to the first tube body 11 along the conveying direction, thereby forming a positive pressure blowing side; the second side wall 133 is located on the side of the dust removal port 131 close to the second tube body 12 along the conveying direction, thereby forming a negative pressure exhaust side.

[0063] In some embodiments, see Figure 3As shown, the gap between the second side wall 133 and the product surface can be equal to the gap between the first side wall 132 and the product surface, which can facilitate processing and at the same time ensure that the negative pressure exhaust side is at a certain distance from the product surface to ensure gas circulation.

[0064] In some embodiments, the gap between the second side wall 133 and the product surface is larger than the gap between the first side wall 132 and the product surface to ensure that the negative pressure exhaust side is at a sufficient distance from the product surface, thereby ensuring gas circulation. Since the positive pressure blowing does not require a sufficient distance to achieve an ideal dust removal effect, the positive pressure blowing side can be as close to the product surface as possible to ensure that the dust is completely separated from the product surface. At the same time, negative pressure exhaust is set at a relatively close distance to suck away the dust that has separated from the product surface as soon as possible.

[0065] In some embodiments, please combine Figure 1-Figure 3 As shown, the first tube body 11 and the second tube body 12 are arranged in pairs in the second direction; multiple pairs of the first tube body 11 and the second tube body 12 are arranged side by side along the first direction on the dust removal head 10;

[0067] The dust removal head 10 also includes a fourth tube body 15, which is arranged along the first direction. The fourth tube body 15 is simultaneously connected to one end of each second tube body 12 away from the dust removal port 131, and the fourth tube body 15 is suitable for connecting multiple second tube bodies 12 in parallel.

[0068] For further information, see Figure 1 As shown, one end of the third tube body 14 along the first direction is connected to the positive pressure air source, and the other end is sealed. The third tube body 14 is also connected to one end of each first tube body 11 away from the dust removal port 131; one end of the fourth tube body 15 along the first direction is connected to the negative pressure exhaust device, and the other end is sealed. The fourth tube body 15 is also connected to one end of each second tube body 12 away from the dust removal port 131, thereby ensuring that only one working surface (located at the dust removal port 131) is in contact with the atmospheric environment, avoiding the problem of difficulty in centralized dust extraction after the dust is blown into the entire space.

[0069] In this embodiment, multiple first tube bodies 11 are connected in parallel by setting a third tube body 14, and multiple second tube bodies 12 are connected in parallel by setting a fourth tube body 15, so that multiple dust removal ports 131 are arranged side by side along the first direction. During the product conveying process, dust can be removed from the product surface simultaneously through the multiple dust removal ports 131, thereby improving the dust removal efficiency.

[0070] It should be noted that in the specific implementation process, please refer to Figure 1 As shown, the dust removal head 10 also includes a connecting block 17. The technician can use the connecting block 17 to integrate multiple first tube bodies 11, multiple second tube bodies 12, third tube bodies 14 and fourth tube bodies 15 into an integrated structure, so as to facilitate the positioning and fixing of the dust removal head 10 on the product transmission line. The specific connection form between the connecting block 17 and the multiple first tube bodies 11, multiple second tube bodies 12, third tube bodies 14 and fourth tube bodies 15 can be adjusted according to actual production conditions, which will not be repeated here.
