Description

[0001] This utility model relates to the field of sheet metal processing, and in particular to a non-contact dust removal machine. Background Technology
[0002] The substrate is the basic material for manufacturing PCBs. Generally, the substrate is a copper-clad laminate. In the manufacturing process of single-sided and double-sided printed circuit boards, selective processing such as hole machining, chemical copper plating, electrolytic copper plating, and etching are performed on the substrate material-copper-clad laminate to obtain the required circuit pattern. During the processing of the substrate, static electricity easily attracts dust, so dust removal is required. However, in the existing technology, foreign objects on the substrate are scattered everywhere during substrate dust removal, causing them to be re-adsorbed onto the substrate, resulting in incomplete substrate dust removal and cleaning. Therefore, a non-contact dust removal machine is proposed. Utility Model Content

Furthermore, the first high-pressure rotary air knife and the second high-pressure rotary air knife... During the blowing process, the first and second vacuum suction ports simultaneously draw air, creating a negative pressure zone between the first and second dust removal hoods.

When the lifting cylinder drives the lifting rod upward, it also drives the first dust removal hood upward, opening the gap between the first and second dust removal hoods. This allows subsequent operators to clean the first and second sheet metal traction rollers, preventing any impact on the subsequent sheet metal conveying and cleaning.

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.
[0026] Please see Figure 1-6In this embodiment of the utility model, the non-contact dust collector includes a dust collector body 1. A support frame 3 is vertically arranged inside the dust collector body 1, and a second dust collector hood 22 is horizontally arranged inside the support frame 3. A first dust collector hood 21 is horizontally arranged at the top of the second dust collector hood 22, and the first dust collector hood 21 is horizontally mounted at the top of the support frame 3 and can move up and down at the top of the support frame 3. A first transmission pipe 15 is horizontally arranged at the top of the first dust collector hood 21, and a first high-pressure rotary air knife is vertically arranged at the bottom of the first transmission pipe 15. 16, and at least three first high-pressure rotary air knives 16, the first high-pressure rotary air knives 16 are connected to the first transmission pipe 15 by a pipeline, and the first transmission pipe 15 is provided with first vacuum suction ports 17 on both sides, and the first vacuum suction ports 17 are connected to the first transmission pipe 15 by a pipeline. The second dust collector hood 22 has a second transmission pipe 18 horizontally arranged at the top inside, and a second high-pressure rotary air knife 19 is vertically arranged at the top of the second transmission pipe 18, and at least three second high-pressure rotary air knives 19 are provided. The second high-pressure rotary air knives 19 are connected to the second high-pressure rotary air knife 15 by a pipeline. The transmission pipes 18 are connected by pipes, and a second vacuum suction port 20 is provided on both sides of the second transmission pipe 18. The second vacuum suction port 20 is connected to the second transmission pipe 18 by pipes. So when the sheet material is inserted laterally from one side of the dust collector body 1 and moved onto the support frame 3, the sheet material is horizontally placed between the first dust collector hood 21 and the second dust collector hood 22. At this time, the first high-pressure rotating air knife 16 at the bottom of the first dust collector hood 21 and the second high-pressure rotating air knife 19 at the top of the second dust collector hood 22 blow air at high speed onto the surface and bottom of the sheet material, respectively. Foreign objects on the surface of the sheet are blown up and foreign objects on the bottom surface of the sheet are blown down, and the sheet is cleaned by blowing air from both the top and bottom. When the first high-pressure rotary air knife 16 and the second high-pressure rotary air knife 19 blow air, the first vacuum suction port 17 and the second vacuum suction port 20 simultaneously suck air, so that a negative pressure zone is formed between the first dust removal hood 21 and the second dust removal hood 22, thereby extracting and recovering foreign objects blown up from the surface of the sheet and foreign objects blown down from the bottom surface of the sheet, effectively preventing foreign objects from scattering. After cleaning, the sheet moves from the support frame 3 and slides out from the other side of the dust removal machine body 1.
[0027] A first diversion conveying pipe 7 is provided between the first dust removal hood 21 and the first transmission pipe 15. The first diversion conveying pipe 7 is located at the top of the outside of the first dust removal hood 21 and is connected to the first vacuum suction port 17. This allows the first vacuum suction port 17 to extract foreign objects and discharge the extracted foreign objects from inside the first dust removal hood 21 through the first diversion conveying pipe 7.
[0028] A second diversion conveying pipe 14 is provided between the second dust removal hood 22 and the second transmission pipe 18. The second diversion conveying pipe 14 is located at the bottom of the outside of the second dust removal hood 22 and is connected to the second vacuum suction port 20. This allows the second vacuum suction port 20 to extract foreign objects and discharge the extracted foreign objects from inside the second dust removal hood 22 through the second diversion conveying pipe 14.
[0029] The second dust removal hood 22 is provided with a plurality of second drive shafts 11, and each of the plurality of second drive shafts 11 is fitted with a first sheet material traction roller 5. The plurality of second drive shafts 11 are all located laterally on the surface of the second dust removal hood 22, and the second drive shafts 11 rotate synchronously with the first sheet material traction roller 5. Thus, the first sheet material traction roller 5 can be driven to roll on the surface of the second dust removal hood 22 through the second drive shafts 11, thereby driving and pulling the sheet material inserted horizontally inside the dust removal machine body 1, so as to clean and remove dust from the sheet material in the future.
[0030] Each of the plurality of drive shafts 11 is driven and coupled to a first drive shaft 10, which is located laterally at the top of the outer side of the support frame 3 and rotates at the top of the outer side of the support frame 3. A motor 13 is provided between the first drive shaft 10 and the support frame 3 and is fixed to the side of the support frame 3. The motor 13 is driven and connected to the first drive shaft 10, and a belt 12 is driven and connected between the motor 13 and the first drive shaft 10. The belt 12 causes the motor 13 to drive the first drive shaft 10 to rotate, which in turn drives the plurality of drive shafts 11 to rotate and causes the first sheet material traction roller 5 to roll on the surface of the second dust removal hood 22, thereby driving and pulling the sheet material inserted horizontally inside the dust removal machine body 1 for subsequent cleaning and dust removal of the sheet material.
[0031] A motor fixing frame 4 is provided between the motor 13 and the support frame 3. The motor fixing frame 4 is vertically located on one side of the support frame 3, and the motor 13 is horizontally located at the top of the motor fixing frame 4. Thus, the motor 13 can be fixed to the support frame 3 through the motor fixing frame 4.
[0032] The first dust collector hood 21 is provided with several third drive shafts (not shown in the figure), and each of the several third drive shafts is fitted with a second sheet material traction roller 6. The several third drive shafts are all located laterally at the bottom surface of the first dust collector hood 21, and the third drive shafts rotate synchronously with the second sheet material traction roller 6. Thus, the third drive shafts can be driven to roll on the second dust collector hood 22, thereby driving and traction the sheet material inserted horizontally inside the dust collector body 1, so as to clean and remove dust from the sheet material in the future.
[0033] A cylinder 9 is provided between the first dust cover 21 and the support frame 3, and the cylinder 9 is vertically located at the top of the support frame 3. The cylinder 9 and the support frame 3 are connected by a drive. A lifting frame 8 is provided between the cylinder 9 and the first dust cover 21, and the lifting frames 8 are located laterally on both sides of the first dust cover 21. The cylinder 9 and the lifting frame 8 are connected by a drive. When the cylinder 9 drives the lifting frame 8 to lift, it simultaneously drives the first dust cover 21 and the support frame 3 to lift, thereby adjusting the distance between the first dust cover 21 and the second dust cover 22 to accommodate plates of different thicknesses.
[0034] The dust collector body 1 is provided with a plate inlet and outlet 2, and the plate inlet and outlet 2 are formed on both sides of the dust collector body 1. The plate inlet and outlet 2 are connected to the dust collector body 1, so that the external plate can enter the dust collector body 1 for cleaning and dust removal or the cleaned plate can slide out from the dust collector body 1.
[0035] A lifting cylinder 23 is also provided between the first dust removal hood 21 and the support frame 3. The lifting cylinders 23 are all obliquely located on both sides outside the support frame 3. The top of the lifting cylinder 23 is vertically driven to provide a lifting air rod 24. The other end of the lifting air rod 24 is movably connected to the two sides outside the first dust removal hood 21. Thus, when the lifting cylinder 23 drives the lifting air rod 24 to move upward, it drives the first dust removal hood 21 to move upward, so that the first dust removal hood 21 and the second dust removal hood 22 are in an open state, so that the subsequent operators can clean the first plate traction roller 5 and the second plate traction roller 6, preventing it from affecting the subsequent plate conveying and cleaning.
[0036] The first dust hood 21 is also electrically equipped with a first static eliminator 25, and the first static eliminator 25 is horizontally fixed to both sides inside the first dust hood 21; the second dust hood 22 is also electrically equipped with a second static eliminator 26, and the second static eliminator 26 is horizontally fixed to both sides inside the second dust hood 22, thereby eliminating the attraction force of foreign objects on the board material due to static electricity through the first static eliminator 25 and the second static eliminator 26.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
