Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a splash-proof workbench for circuit board processing. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. Circuit boards are divided into single-sided boards (on the most basic PCB, parts are concentrated on one side and wires are concentrated on the other side. Because wires only appear on one side, this type of PCB is called a single-sided circuit board), double-sided boards (an extension of single-sided boards. When single-layer wiring cannot meet the needs of electronic products, double-sided boards are used. Both sides have copper cladding and wiring, and the lines between the two layers can be connected through vias to form the required network connection), and multi-layer circuit boards (refers to printed boards with more than three layers of conductive graphic layers and insulating materials in between, which are laminated and interconnected as required. Multi-layer circuit boards are the product of the development of electronic information technology towards high speed, multi-function, large capacity, small size, thinness, and lightweight). In the process of circuit board processing, it is necessary to go through specified processes, among which cutting processing through a cutting table is a more important process.

[0003] At present, the conventional workbench used for circuit board processing usually utilizes a cylinder to push the cutting blade downward to cut the circuit board during use. The cutting blade will generate a lot of debris splashing when cutting the circuit board. The splashing debris will have a large kinetic energy and easily cause injury to the operator. Therefore, some workbenches are now equipped with protective covers to prevent the debris generated by cutting from splashing and injuring surrounding personnel. However, although the splashing debris is intercepted to prevent it from splashing around, it will scatter near the workbench, requiring the operator to clean it frequently, which is inconvenient to use.

[0022] In this example, the cleaning mechanism also includes a fan blade 12, which is fixedly connected to the lower output end of the dual-axis motor 11, and the fan blade 12 is located in the collecting chamber. The upper output end of the dual-axis motor 11 is connected to a rotating shaft 14, and the top of the rotating shaft 14 is connected to a hexagonal prism 16. A rotating column 15 is rotatably embedded in the filter 10, and a hexagonal groove matching the hexagonal prism 16 is opened at the bottom of the rotating column 15.

At the same time, the brush holder 17 can be driven to drive the bristles to clean the filter screen 10 to avoid debris accumulation and clogging the filter screen 10, thereby affecting the filtering effect of the filter screen 10. In addition, it is convenient to disassemble and install the filter box 9. In this example, the blowing assembly includes an air guide hood 25, which is installed on the outside of the collecting chamber at the bottom of the workbench 1. A three-way valve 26 is connected to the bottom of the air guide hood 25. Both ends of the three-way valve 26 are connected to a hose 27, and one end of the hose 27 is connected to the cavity opened in the clamp 7. The clamp 7 is symmetrically embedded with inclined blowing heads on the upper and lower sides relative to the inner wall.

Through the blowing assembly, the wind blown by the cleaning mechanism can be blown out through the blowing head to clean the debris scattered on the surface of the circuit board and the grid plate 5, and blow it away and drop it into the collecting groove. At the same time, the bristles at the bottom of the clamp 7 can be used to clean some of the debris scattered on the surface of the grid plate 5, thereby improving the cleaning effect. In this example, the collecting chamber is funnel-shaped, the rotating column 15 is rotatably connected to the filter screen 10 through a bearing, a support ring 18 is provided inside the filter box 9, and the cross section of the support ring 18 is semicircular, and a slot matching the support ring 18 is provided on the side wall of the brush holder 17, so that the brush holder 17 can be supported and guided by the support ring 18 to improve the stability of its movement. In this example, the dual-axis motor 11 is fixedly connected to the fixing frame 13, and the fixing frame 13 is fixedly connected to the screw nut, and the height of the adjustment groove is greater than the length of the hexagonal prism 16, so that the height of the adjustable fixing frame 13 is greater than the length of the hexagonal prism 16, which can ensure that the hexagonal prism 16 is moved out of the hexagonal groove.In this example, guide strips 8 are provided on all four sides of the protective cover 2, and the guide strips 8 are fixedly connected to the workbench 1 and the protective cover 2. The cross-section of the guide strip 8 is a right triangle, and the guide strip 8 is located under the telescopic rod 6 to guide the debris on the edge of the grid plate 5 to the grid plate 5 for collecting the debris.

[0023] The working principle of the utility model is as follows: when in use, the circuit board to be processed is placed on the top of the grid plate 5 in the protective cover 2, the protective door is closed, and then the telescopic rod 6 is started to push the clamping plate 7 to clamp it, and then the cutting motor and the cutting knife can be pushed down by the cylinder 4 to cut the circuit board, and the cutting position can be changed by sliding on the electric slide rail 3. The debris generated by the cutting will be intercepted by the protective cover 2, so as to prevent the debris from splashing and injuring the surrounding staff. During the cutting process, the dual-axis motor 11 is started to drive the fan blades 12 to rotate, thereby generating a negative pressure suction force, and then sucking the scattered debris on the grid plate 5. The fallen debris enters the collection tank and is collected in the filter box 9. At the same time, the wind blown out by the rotation of the fan blades 12 is introduced into the three-way valve 26 through the air guide cover 25, and then the three-way valve 26 is distributed to the two hoses 27, so that it is guided to the two clamping plates 7 through the hoses 27, and then blown out through the upper and lower blowing heads, so that the debris scattered on the surface of the circuit board and the grid plates 5 on both sides is blown away, so that the debris falls into the filter box 9 through the gap on the grid plate 5 for collection and treatment. At the same time, when the circuit board is removed after cutting, the telescopic rod 6 drives the clamping plate 7 to move, so that the bristles at the bottom of the clamping plate 7 clean the grid plate 5, so that the part scattered on the grid plate 5 is removed. The debris is swept into the collection chamber and collected by the filter box 9, which improves the cleaning effect. At the same time, the rotation of the dual-axis motor 11 will drive the rotating shaft 14, so that the rotating shaft 14 drives the hexagonal prism 16 and then drives the rotating column 15 to rotate, so that the rotating column 15 drives the brush holder 17 to rotate, thereby driving the bristles on the brush holder 17 to clean the filter screen 10 to avoid blockage and thus affect the filtering effect and ventilation volume; when the filter box 9 needs to be removed, the rotating rod 21 can be twisted to rotate, and at the same time, the rotating rod 21 will drive the synchronous wheel 23 thereon, and drive the synchronous belt 24 on the other side through the synchronous belt 24, so that the synchronous belt 24 drives the rotating rod 21 on the other side to rotate, that is, The rotating rod 21 can drive the bevel gear 22 to rotate, and then the bevel gear 22 drives the bevel gear 1 20 meshing with it to rotate, so that the bevel gear 1 20 drives the screw rod 19, thereby driving the fixing frame 13 to drive the dual-axis motor 11 to move downward, so that the hexagonal prism 16 is separated from the hexagonal groove, and then the handle can be pulled out to remove the filter box 9, and the collected debris can be processed, or the filter screen 10 can be cleaned and replaced, and the filter box 9 and filter screen 10 can be installed. The above steps can be reversed to reinsert the hexagonal prism 16 into the hexagonal groove to complete the installation of the filter screen 10, making it convenient to disassemble and install the filter screen 10, easy to use, and more practical.
