Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board processing technology, and in particular to a drilling device for processing printed circuit boards. Background Technology
[0002] In the manufacturing process of printed circuit boards, the drilling process is a crucial step, as the quality of drilling directly affects the electrical performance, mechanical strength, and subsequent assembly processes of the circuit board.
[0003] Currently, common drilling devices for printed circuit board (PCB) processing on the market mainly consist of a processing table and a robotic arm mounted on one side of the processing table. The output end of the robotic arm is equipped with a drilling component. In actual operation, the robotic arm moves the drilling component to a designated position above the processing table to perform drilling operations on the PCB placed on the processing table. However, existing drilling equipment still has shortcomings in use. First, the drilling process of circuit boards generates a large amount of waste such as metal shavings and dust. This waste not only pollutes the processing environment and harms the health of operators, such as causing respiratory diseases due to long-term inhalation of dust, but also adheres to the surface of the circuit board and the components of the drilling equipment. The shavings and dust adhering to the surface of the circuit board will affect the quality of subsequent processes. Although some existing drilling equipment is equipped with a dust collection device at the drilling position of the drilling component to absorb the waste, in the actual drilling process, burrs are generated. These burrs have a certain degree of adhesion, making it impossible for some waste to be directly absorbed. These residual wastes will still accumulate on the surface of the circuit board, affecting the subsequent production quality of the circuit board and causing inconvenience in actual use.
[0004] Therefore, it is necessary to provide a new drilling device for printed circuit board processing to solve the above-mentioned technical problems. Utility Model Content

A scraper is slidably provided on the bottom wall of the cavity. A scraper blade is fixed at the bottom of the scraper blade, and the bottom of the scraper blade is in contact with the bottom wall of the cavity.
[0007] Preferably, the clamping mechanism includes a first electric push rod, a pressure plate, and multiple telescopic rods. The two ends of the first electric push rod and the multiple telescopic rods are respectively fixedly connected to the top of the processing table body and the bottom of the pressure plate.

The first connector includes a first conduit, and a cavity near the mounting plate is connected to the interior of the mounting plate through the first conduit.
[0009] Preferably, the filter assembly includes two ventilation plates and a filter plate, with the filter plate sandwiched between the two ventilation plates.

[0011] Preferably, the top of the pressure plate is provided with an installation groove, and an insert plate is inserted into the installation groove. The tops of the pressure plate, insert plate, and installation plate are all formed with straight holes for drilling. The insert plate has a cavity I inside. A second electric push rod is fixed to the bottom wall of the insert plate. A scraper is fixed to the output end of the second electric push rod. The scraper slides on the bottom wall of the cavity I. Limiting plates are fixed to both ends of the insert plate. Both limiting plates are inserted into the installation groove. A cavity II is formed inside one of the limiting plates. The cavity I and the cavity II are connected. A second connecting pipe is fixed to the top of one of the limiting plates. The second connecting pipe is connected to the inside of the cavity II. The other end of the second pipe is fixedly connected to one end of one of the second connecting pipes.

[0013] Compared with related technologies, the drilling device for printed circuit board processing provided by this utility model has the following advantages: This invention features a dust-collecting component and a dust-collecting unit. The dust-collecting component is located between the clamping mechanism and the processing table body, enabling dust collection on the surface of the processing table body 1 and the area surrounding the clamping mechanism. One end of the dust-collecting unit extends into the cavity 1 inside the clamping mechanism, effectively adsorbing dust and debris generated within the cavity 1 during drilling. The top and bottom dual-dust-collecting design significantly expands the dust-collecting range, reduces waste accumulation in the processing area, effectively prevents waste pollution of the processing environment, and lowers the risk of respiratory diseases and other health problems for operators due to long-term dust inhalation. By sliding a scraper on the bottom wall of the cavity of the clamping mechanism, and fixing a scraper blade at the bottom of the scraper blade to fit against the bottom wall of the cavity, during the drilling operation, when waste cannot be directly adsorbed by the dust collection component due to burrs, the scraper blade can scrape the bottom wall of the cavity by sliding the scraper blade, scraping up the debris, dust and long burrs on the top of the circuit board that are attached to the bottom wall, making them suspended and easier to be adsorbed and removed by the dust collection unit. This solves the problem that some waste cannot be directly adsorbed due to drilling burrs in existing drilling devices and remains on the surface of the circuit board, and reduces the adhesion of burrs to a certain extent.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please refer to the following: Figures 1 to 6 ,in, Figure 1 A schematic diagram of the overall structure of the drilling device for processing printed circuit boards provided by this utility model; Figure 2 This is a schematic diagram of the clamping assembly. Figure 3 This is a schematic diagram of the structure of cavity one; Figure 4 A schematic diagram of the overall structure of the drilling device for processing printed circuit boards provided by this utility model; Figure 5 for Figure 4 Enlarged view of point A in the middle; Figure 6 for Figure 4 Enlarged view of point B in the middle.
[0018] In some embodiments, such as Figures 1 to 6 As shown, the machine includes a processing table body 1 and a robotic arm 2 located on one side of the processing table body 1. A drilling assembly is fixed at the output end of the robotic arm 2. A clamping mechanism is provided on the top of the processing table body 1. A dust collection assembly is fixed on the top of the processing table body 1. The dust collection assembly is located between the clamping mechanism and the processing table body 1. A cavity 421 is formed inside the clamping mechanism. A dust collection unit is provided on the top of the clamping mechanism. One end of the dust collection unit extends into the cavity 421. A scraper 423 is slidably provided on the bottom wall of the cavity 421. A scraper 424 is fixed at an incline at the bottom of the scraper 423. The bottom of the scraper 424 is in contact with the bottom wall of the cavity 421. Specifically, by setting up a dust collection component and a dust collection unit, the dust collection component is located between the clamping mechanism and the processing table body 1, and can perform dust collection on the surface of the processing table body 1 and the area around the clamping mechanism; one end of the dust collection unit extends into the cavity 421 inside the clamping mechanism, and can effectively adsorb the dust and debris generated in the cavity 421 during the drilling process. The top and bottom dual dust collection design greatly expands the dust collection range, reduces the accumulation of waste in the processing area, effectively avoids waste pollution of the processing environment, and reduces the risk of respiratory diseases and other health problems caused by long-term dust inhalation for operators. A scraper 423 is slidably installed on the bottom wall of the cavity 421 of the clamping mechanism, and a scraper 424 is fixed at the bottom of the scraper 423 at an incline to fit against the bottom wall of the cavity 421. During the drilling operation, when waste cannot be directly adsorbed by the dust collection component due to the adhesion of burrs, the scraper 424 can scrape the bottom wall of the cavity 421 by sliding the scraper 423, scraping up the debris, dust and long burrs on the top of the circuit board attached to the bottom wall, making them suspended, and thus easier to be adsorbed and removed by the dust collection unit. This solves the problem that some waste cannot be directly adsorbed due to drilling burrs in the existing drilling device and remains on the surface of the circuit board.
[0019] In some embodiments, reference is made to Figures 1 to 6 As shown, the clamping mechanism includes a first electric push rod 3, a pressure plate 4, and multiple telescopic rods 31. The two ends of the first electric push rod 3 and the multiple telescopic rods 31 are respectively fixedly connected to the top of the processing table body 1 and the bottom of the pressure plate 4. The top of the processing table body 1 is also fixed with an internally hollow mounting plate 32. The mounting plate 32 is located directly below the pressure plate 4. A pad 322 is fixed on the top of the mounting plate 32. The circuit board is placed on the top of the pad 322. One end of the dust collection component is connected to the mounting plate 32 through a first connector. The dust collection assembly includes a collection box 33, a cover plate 331 is rotatably mounted on the top of the collection box 33, a pull ring 3311 is fixed on the top of the cover plate 331, a ventilation hole 332 is opened on one side of the collection box 33, and a filter assembly is fixed on the bottom wall of the collection box 33. The filter assembly divides the interior of the collection box 33 into two independent cavities. A fan 333 is fixed in the cavity away from the mounting plate 32, and the cavity closer to the mounting plate 32 is connected to the interior of the mounting plate 32 through a first connector. The first connector includes a first pipe 34, and the cavity on the side near the mounting plate 32 is connected to the interior of the mounting plate 32 through the first pipe 34; The filter assembly includes two ventilation plates 334 and a filter plate 335. The filter plate 335 is sandwiched between the two ventilation plates 334. The ventilation plates 334 are preferably perforated metal plates made of stainless steel, and uniformly distributed holes are formed on the metal plates through a perforation process. The filter plate 335 is preferably an activated carbon filter screen to filter dust. The vacuuming unit is fixed to the surface of the first pipe 34. The vacuuming unit includes a first connecting pipe 341. The first connecting pipe 341 is fixed to the surface of the first pipe 34. The other end of the first connecting pipe 341 is fixed to a second pipe 35. The other end of the second pipe 35 is connected to the interior of the pressure plate 4. The top of the pressure plate 4 has a mounting groove 41, and an insert plate 42 is inserted into the mounting groove 41. The tops of the pressure plate 4, insert plate 42, and mounting plate 32 all have straight holes 4211 for drilling. The insert plate 42 has a cavity 421 inside. A second electric push rod 422 is fixed to the bottom wall of the insert plate 42. A scraper 423 is fixed to the output end of the second electric push rod 422. The scraper 423 slides on the bottom wall of the cavity 421. Limiting plates 4212 are fixed to both ends of the insert plate 42, and both limiting plates 4212 are inserted into the mounting plate 32. Inside the groove 41, a cavity 4213 is formed inside one of the limiting plates 4212. The cavity 421 and the cavity 4213 are connected. A second connecting pipe 4215 is fixed to the top of one of the limiting plates 4212. The second connecting pipe 4215 is connected to the cavity 4213. The other end of the second pipe 35 is fixedly connected to one end of one of the second connecting pipes 4215. A first inclined plate 321 is fixed to the bottom wall of the mounting plate 32. A second inclined plate 4214 is also fixed to the bottom wall of the cavity 421. An operating table 11 is fixed on one side of the processing table body 1. The drilling assembly includes a fixing frame 21, which is fixed to the output end of the robotic arm 2. The robotic arm 2 is used to precisely position the drilling assembly to a designated position for drilling operations. The drilling is controlled by a display screen on the surface of the operating table 11, which is existing technology and will not be described in detail here. A motor 22 is fixed at the bottom of the fixing frame 21, and a drill bit 23 is fixed at the output end of the motor 22. The operation of the motor 22 drives the drill bit 23 to rotate to achieve the drilling function. The design of the first inclined plate 321 on the bottom wall of the mounting plate 32 and the second inclined plate 4214 on the bottom wall of the cavity 421 can guide the flow direction of airflow and waste. That is, when the dust collection component is adsorbing, dust and debris slide from the first inclined plate 321 and the second inclined plate 4214 into the first pipe 34 and the second pipe 35 and are sucked into the collection box. The clamping assembly mainly clamps the end of the circuit board, that is, the pressure plate 4 is used to limit the edge of the top of the circuit board. The material of the pad 322 is preferably rubber to protect the circuit board from being crushed during drilling. Specifically, during use, the operator places the circuit board to be drilled on the pad 322 on top of the mounting plate 32, activates the first electric push rod 3, which drives the pressure plate 4 to move downwards. The telescopic rod 31 provides auxiliary support and stability, causing the pressure plate 4 to press the circuit board firmly, thus clamping the circuit board. The operator controls the movement of the robotic arm 2 via the control panel 11, moving the drilling assembly to the designated drilling position above the circuit board, such as the straight hole 4211. The operator then activates the motor 22, which drives the drill bit 23 to rotate. Simultaneously, the robotic arm 2 moves the drill bit 23 downwards to drill the circuit board. During the drilling process, the fan 333 of the dust collection assembly is activated. The operation of the fan 333 creates negative pressure inside the collection box 33. The dust is drawn through the first pipe 34, the first connecting pipe 341, and the second pipe inside the mounting plate 32, the pressure plate 4, and the first and second cavities 4211 and 4213 of the insert plate 42. 35 is connected to the second connecting pipe 4215. Under negative pressure, the metal shavings and dust generated during drilling enter the cavity 421 through each straight hole 4211. Some of the shavings attached to the bottom wall of the cavity 421 are scraped up by the scraper 423. The scraper 423 slides on the bottom wall of the cavity 421 under the action of the second electric push rod 422. Then, together with other waste, it is sucked into the collection box 33 through the second pipe 35, the first connecting pipe 341, and the first pipe 34. The air entering the collection box 33 passes through the filter assembly, the ventilation plate 334 and the filter plate 335 to filter the shavings and dust in the air, so that the clean air is discharged from the ventilation hole 332. The shavings and dust remain in the collection box 33. When a certain amount of shavings and dust has been collected in the collection box 33, the operator can open the cover plate 331 through the pull ring 3311 to clean the waste in the collection box 33.
[0020] Furthermore, the scraper 423 provided on the bottom wall of the internal cavity 421 of the insert 42 can scrape up the debris that is difficult to be directly adsorbed due to the adhesion of burrs during the drilling process, so that it is suspended and more easily sucked into the collection box 33 by the dust collection system. This effectively solves the problem of difficult cleaning of residual waste, further improves the dust collection effect, and ensures the quality of subsequent processes of the circuit board.
[0021] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0022] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
