Description

Technical Field

[0001] This application relates to the field of PCB manufacturing, and in particular to a single-sided board drilling device and its manufacturing process. Background Technology

[0002] PCB, or Printed Circuit Board, is the provider of electrical connections for electronic components. Using PCB can greatly save space and reduce wiring and assembly errors. A single-sided PCB is the most basic PCB, with components concentrated on one side and wires on the other. Single-sided PCBs require drilling using a positioning drilling device during manufacturing.

[0003] CN213257241U discloses a precision positioning and drilling device for a single-sided PCB, including a drilling table, a drilling mechanism slidably connected to the surface of the drilling table, and a fixing frame screwed to the surface of the drilling table. A fixing drawer is slidably connected inside the fixing frame, a limit spring is welded to the inner wall of the fixing drawer, and a positioning groove is provided inside the fixing drawer. A positioning clamp is slidably connected to the surface of the positioning groove. During drilling, the single-sided PCB is placed inside the fixing drawer, fixed by the positioning clamp, and then drilling is performed.

[0004] Because drilling holes in single-panel veneers produces debris, the aforementioned drilling device places the veneer inside a fixed drawer during drilling. This debris accumulates inside the drawer, making cleaning difficult. Furthermore, if the debris isn't cleaned promptly, the next veneer to be drilled will be pressed down on top of it, reducing the drilling accuracy and quality. Summary of the Invention

[0005] To improve the drilling accuracy and quality of single-sided panels, this application provides a single-sided panel drilling device and its manufacturing process.

[0006] A single-sided panel punching device includes a processing table, a collection box, and a punching assembly. The punching assembly is disposed above the processing table, and the collection box is fixedly connected to the bottom of the processing table. The punching assembly includes a transverse slide that can slide laterally relative to the processing table, a vertical slide disposed on the transverse slide and movable vertically relative to the transverse slide, and a drilling machine that can move along the length of the vertical slide. A drill bit is disposed at one end of the drilling machine facing the processing table, and the drilling machine is provided with an air blowing head, the outlet of which faces the end of the drill bit. The processing table has a slot, the opening of which is located on the side wall of the processing table. The processing table also has a processing port, which communicates with the slot and the interior of the collection box. A material discharge port is disposed on the side wall of the slot, and the material discharge port communicates with the interior of the collection box.

[0007] By adopting the above technical solution, the processing table supports the punching assembly. The horizontal carriage allows the drilling machine to slide laterally, while the vertical carriage allows it to slide vertically. The drilling machine on the vertical carriage can slide longitudinally, allowing the drill bit to move in three-dimensional space, facilitating punching of the one-way panel. The slot is used to limit the position of the single-sided panel. The slot opening is located on the side wall of the processing table, allowing the single-sided panel to be easily inserted horizontally. The processing port is connected to the slot, and the single-sided panel inserted into the slot can be seen from the processing port, ensuring that the part of the single-sided panel to be punched is suspended, allowing the drill to penetrate the single-sided panel. An air blowing head is also included. The outlet direction faces the drill bit, so the air blower can blow away the debris generated during punching, reducing the impact of debris on punching. The side wall of the machining port will block the debris blown up by the air blower, reducing debris splashing and facilitating subsequent cleaning. The side wall of the slot has a material drop groove. Debris that does not fall into the collection box from the machining port will also fall into the collection box from the material drop groove under the blowing of the air blower. During punching, debris can fall into the collection box from either the machining port or the material drop groove, which can clean up the generated debris in time, thereby improving the single-sided panel drilling accuracy and quality.

[0008] Optionally, the vertical carriage is provided with a longitudinal carriage and a longitudinal drive member for driving the longitudinal carriage to move. The longitudinal carriage is connected to a dust cover, and the drilling machine is fixedly mounted on the longitudinal carriage and located inside the dust cover.

[0009] By adopting the above technical solution, the longitudinal drive component can drive the longitudinal carriage to move in the longitudinal direction of the vertical carriage. The drilling machine and the dust cover block are both set on the longitudinal carriage. When the longitudinal carriage moves, the drilling machine and the dust cover will move synchronously, so that when the drill bit punches a hole at any position on the single panel, the flying debris can be blocked by the dust cover, so that the debris can fall into the collection box from the processing opening or accumulate on the single panel located at the processing opening.

[0010] Optionally, the dust cover is connected to the longitudinal slide via a connector. One end of the connector is threaded, and the other end of the connector is fixed with an anti-detachment ring. The threaded end of the connector is threadedly connected to the longitudinal slide. The dust cover can slide along the axial direction of the connector. A dustproof elastic element is connected between the dust cover and the longitudinal slide. The dustproof elastic element has a tendency to force the dust cover to move towards the processing table. The anti-detachment ring is used to restrict the movement of the dust cover towards the processing table.

[0011] By adopting the above technical solution, the connector is threaded to the longitudinal carriage, facilitating the disassembly of the dust cover and thus making it easier to clean debris adsorbed on the inner wall of the dust cover. The anti-detachment ring prevents the dust cover from detaching from the connector. Under the action of the dust cover elastic component and the anti-detachment ring, the drill bit can continue to move downward to punch the single panel at the machining opening when the dust cover is against the surface of the machining table. During punching, because the dust cover is against the surface of the machining table, the flying debris is either blocked by the dust cover, blocked by the side wall of the machining opening, or blown to the side wall of the slot by the air blower and then falls into the material drop port, ultimately reducing the range of debris flying and facilitating debris cleaning.

[0012] Optionally, the drilling machine and the air blowing head are connected by a drive plate, which can rotate relative to the axis of the drilling machine. The vertical slide is connected to an air pump, which is connected to the air blowing head via a hose. The drilling machine is equipped with a servo motor for driving the drive plate to rotate. The servo motor controls the rotation of the drive plate so that the position of the air blowing head is between the midpoint of the drill bit and the processing opening.

[0013] By adopting the above technical solution, the drive disc can rotate relative to the drilling machine, thereby enabling the air blowing head to rotate relative to the drill bit. Controlling the position of the air blowing head allows control over the direction of debris blowing, ensuring the air blowing head directs debris to the nearest discharge port, improving cleaning efficiency. Connecting the air pump to the vertical carriage, rather than the longitudinal carriage, reduces the weight of the longitudinal carriage and lessens the workload on the longitudinal drive components. The air pump and air blowing head are connected via a hose, ensuring the air pump remains connected to the air blowing head while the longitudinal carriage is moving or the drive disc is rotating, allowing the air blowing head to be constantly ventilated and in working condition. The air blowing head is located between the midpoint of the brick and the processing opening; when blowing air, it always directs debris to the nearest discharge port, shortening the debris cleaning path and improving cleaning efficiency.

[0014] Optionally, a bidirectional threaded rod is provided at the end of the material discharge port away from the opening of the slot. The two bidirectional threaded sections of the bidirectional threaded rod are respectively threaded to a positioning plate. The positioning plate has a clamping part that extends from the material discharge port to the slot. An elastic sheet is fixedly provided on the upper wall of the slot, and a first brush is provided at the opening of the slot.

[0015] By adopting the above technical solution, the bidirectional screw is used to drive the positioning plate. The two opposing threads allow the two positioning plates to move closer to each other or further apart, thereby achieving the effect of centering and clamping the single panel. The clamping part can clamp the single panel and reduce the vibration of the single panel during punching. The elastic sheet is used to abut against the single panel entering the slot. On the one hand, it can initially fix the single panel, and on the other hand, it can maintain a certain gap between the upper surface of the single panel and the top of the slot, so that the debris can be blown through the gap to the side wall of the slot and then fall from the discharge port. After the single panel is punched, it is pulled out from the opening of the slot. The first brush can clean the debris accumulated on the upper surface of the single panel, so that the debris falls from the processing port into the collection box.

[0016] Optionally, the bidirectional threaded rod is further fitted with an abutment block; the processing table has a transmission groove, in which a first transmission block and a second transmission block are slidably disposed; one end of the first transmission block has an inclined surface, and the inclined end of the first transmission block protrudes from the slot; a second brush is fixedly connected to the second transmission block; a transmission rope is fixedly connected between the second transmission block and the side wall of the transmission groove; when the first transmission block enters the transmission groove, it can push the transmission rope to force the second brush of the second transmission block to enter the transmission groove; the transmission groove is also provided with a transmission spring for resetting the first transmission block.

[0017] By adopting the above technical solution, the abutment block is set on the bidirectional threaded rod. On the one hand, it prevents the single panel from directly contacting the bidirectional threaded rod; on the other hand, it has a positioning function when the single panel abuts against the abutment block. Before contacting the abutment block, the single panel first contacts the inclined surface of the first transmission block. The single panel pushes the inclined surface of the first transmission block, causing the first transmission block to move into the transmission groove. When the first transmission block moves, it pulls the transmission rope, causing the second transmission block to also move into the transmission groove, and the second brush will enter the transmission groove. Since the first transmission block does not return to its original position when the single panel abuts against the abutment block, the second brush will remain in the transmission groove. Therefore, the drilling process produces... The raw debris is not blocked by the second brush, but accumulates on the upper surface of the abutment block and the single panel. After the single panel is punched, during the removal process, the first transmission block, no longer abutted by the single panel, will come out of the transmission groove under the action of the transmission spring. At this time, the transmission rope will no longer be pushed by the first transmission block, nor will it exert any tension on the second transmission block. The second transmission block will also come out of the transmission groove under its own weight, allowing the second brush to contact the upper surface of the single panel. After contact, as the single panel moves, the second brush will clean up the debris accumulated on the single panel, so that there will not be too much debris left after the single panel is removed from the slot outlet.

[0018] Optionally, a partition plate is fixed inside the cleaning box, dividing the interior of the cleaning box into a collection chamber and a cleaning chamber. The collection chamber is connected to the openings of the material discharge port, the processing port, and the slot, respectively. An elastic plate is fixed inside the collection chamber, and a grinding channel is formed between the elastic plate and the partition plate. A grinding strip is fixed to the inner wall of the grinding channel, and the grinding channel has a grinding inlet and a grinding outlet. The grinding outlet is connected to the collection chamber.

[0019] By adopting the above technical solution, the partition plate can divide the interior of the cleaning box into a collection chamber and a cleaning chamber. The collection chamber is connected to the material discharge port, processing port, and grinding outlet, and is mainly used for collecting debris. The cleaning chamber is used to place the single-sided panels that have been punched and ground. The elastic plate is elastic. When the single-sided panel is inserted into the grinding channel, the elastic plate will deform elastically. Similarly, the elastic plate will have a tendency to abut against the single-sided panel. The grinding inlet is used to insert the single-sided panel. When it is necessary to grind the burrs produced by punching the single-sided panel, it is only necessary to insert and pull it back and forth in the grinding channel, and the grinding strip on the elastic plate can grind the single-sided panel.

[0020] Optionally, the cleaning chamber has a cleaning port, and a rotating plate is provided at the bottom of the cleaning chamber. A pull rope is fixedly connected to the free end of the rotating plate, and one end of the pull rope passes through the partition plate and is fixedly connected to the elastic plate.

[0021] By adopting the above technical solution, the punched and polished single-sided panels can be placed on a rotating plate through the cleaning port. The free end of the rotating plate is fixedly connected to an elastic plate by a pull rope. When polishing the single-sided panel, the elastic deformation of the elastic plate also causes it to rotate under the force transmitted by the pull rope. When water is filled into the cleaning chamber, the rotation of the rotating plate agitates the water and causes it to flow, cleaning the single-sided panels on the rotating plate. When no water is filled into the cleaning chamber, the rotation of the rotating plate causes the single-sided panels to vibrate slightly up and down, which can shake off the tiny debris adhering to the single-sided panels.

[0022] Optionally, a drawer is detachably provided inside the collection chamber, and the partition plate has a guide for material to fall into the drawer.

[0023] By adopting the above technical solution, the drawer is detachably installed in the collection chamber. The debris entering from the material discharge chamber and the processing port will enter the drawer. The guide part, as an extension of the partition plate, allows the debris generated by grinding to also come out from the grinding outlet and enter the drawer under the guidance of the guide part.

[0024] A single-sided panel manufacturing process includes the following steps: Step S1: Coating, drying, cooling, and exposing an aluminum substrate to form a circuit pattern, followed by etching to obtain the single-sided panel body; Step S2: Punching the single-sided panel using the aforementioned punching equipment, and then cleaning up the waste generated from punching; Step S3: Testing the single-sided panel after punching using a testing mechanism, and then applying an oil coating; Step S4: Micro-cutting the single-sided panel after applying the oil coating using a micro-cutting mechanism, and then applying an oxide film.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. During the punching process, the debris can fall into the collection box from either the processing port or the discharge port, which can clean up the generated debris in a timely manner, thereby improving the single-sided panel punching precision and quality.

[0027] 2. By using the dust cover and the side wall of the processing port, the splashing of debris can be blocked, making it easier to clean up the debris later. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0038] This application discloses a single-sided panel punching device and its manufacturing process.

[0039] Reference Figure 1 The punching device 1 includes a processing table 2, a collection box 3 located at the bottom of the processing table 2, and a punching assembly 4 located at the top of the processing table 2. The single panel to be punched is placed on the processing table 2, and then the single panel is punched by the punching assembly 4. The debris generated by punching will enter the collection box 3.

[0040] Reference Figure 1 and Figure 2The punching assembly 4 includes a transverse slide 41, a vertical slide 42, and a longitudinal slide 451. A transverse drive member 411 is fixed to the processing table 2, and the output end of the transverse drive member 411 can drive the transverse slide 41 to move laterally on the processing table 2. The vertical slide 42 is mounted on the transverse slide 41, and a vertical drive member 421 is fixed to the transverse slide 41. The output end of the vertical drive member 421 can drive the vertical slide 42 to move vertically on the transverse slide 41. The longitudinal slide 451 is mounted on the vertical slide 42, and the vertical slide 451 is fixed to the transverse slide 42. A longitudinal drive component 45 is provided, and the output end of the longitudinal drive component 45 can drive the longitudinal slide 451 to move longitudinally on the vertical slide 42. The drilling machine 43 is fixedly mounted on the longitudinal slide 451. In this embodiment, the transverse drive component 411, the longitudinal drive component 45, and the vertical drive component 421 are all motors. The output ends of the three drive the transverse slide 41, the longitudinal slide 451, and the vertical slide 42 to move respectively by means of screw transmission, thereby realizing the movement of the drilling machine 43 in the transverse, longitudinal, and vertical directions relative to the processing table 2.

[0041] The drilling machine 43 is detachably equipped with a drill bit 431 at one end facing the processing table 2. It is fixed by plugging or screwing, so that drill bits 431 of different diameters can be replaced, thereby punching holes of different diameters on a single panel.

[0042] The drilling machine 43 is rotatably equipped with a drive disk 46, and a servo motor is also provided on the drilling machine 43 to drive the drive disk 46 to rotate, allowing the drive disk 46 to rotate relative to the axis of the drilling machine 43; the servo motor is prior art and is not shown in the figure. An air blowing head 44 is fixedly mounted on the drive disk 46, with its outlet facing the end of the drill bit 431. When the drill bit 431 is working, the air blowing head 44 can blow away debris from the drill hole. An air pump 47 is fixedly connected to the vertical carriage 42, and the air pump 47 is connected to the air blowing head 44 via a hose 48. Rotation of the drive disk 46 allows the air blowing head 44 to rotate relative to the axis of the drilling machine 43, controlling the direction of debris blowing. To prevent the hose 48 from tangling with the drilling machine 43, the servo motor controls the rotation angle of the drive disk 46 to 720°, rotating 360° clockwise and 360° counterclockwise.

[0043] Reference Figure 2 and Figure 3The processing table 2 has a slot 21, and the opening 211 of the slot 21 is located on one side of the processing table 2, which is the processing position for the operator. A first brush 55 is provided at the opening 211 of the slot 21, and the operator can insert the single panel that needs to be drilled into the slot 21. During the insertion process, the first brush 55 will perform preliminary cleaning on the upper surface of the single panel. The upper part of the processing table 2 is provided with a processing port 22. The processing port 22 passes through the slot 21 and communicates with the inside of the collection box 3. After the single panel is inserted into the slot 21 through the opening 211 of the slot 21, the elastic piece 54 in the slot 21 will initially fix the edge position of the single panel, so that the drilling machine 43 can drill holes in the single panel at the processing port 22. The drilled debris will fall into the collection box 3 from the processing port 22. The side wall of the slot 21 is provided with a discharge port 23. Since one side of the slot 21 is the opening 211 of the slot 21, the slot 21 has three side walls. The discharge port 23 is U-shaped. The debris accumulated on the single panel can be blown away by the air blower 44, so that the debris enters the collection box 3 from the discharge port 23.

[0044] Reference Figure 3 In order to blow the debris into the nearest discharge port 23, the angle and direction of rotation of the drive disk 46 are controlled by a servo motor. The servo motor is connected to the control panel of the drilling machine 43. The midpoint of the processing port 22 is set as the origin O, forming a planar coordinate system with Y-axis and X-axis. The X-axis is the direction of movement of the transverse slide 41, and the Y-axis is the direction of movement of the longitudinal slide 451. This coordinate system can be displayed on the control panel, which is not shown in the figure.

[0045] Reference Figure 4 and Figure 5The positive direction of the Y-axis is up, and the negative direction is down; the negative direction of the X-axis is left, and the positive direction is right; the position of the drill bit 431 is defined as dynamic coordinate point A, which is the position where the drill bit 431 punches a hole in the single panel. This position parameter can be input in the control panel; the position of the air blowing head 44 is defined as dynamic coordinate point B, which is adjusted in real time according to the movement of dynamic coordinate point A; when dynamic coordinate A is located in the upper left, the servo motor controls the drive disk 46 to rotate, so that dynamic coordinate B is located in the lower right of dynamic coordinate A; at this time, the air blowing head 44 can blow the debris to the upper left drop port 23; similarly; when dynamic coordinate A is located in the upper right / lower left / lower right, the servo motor controls the drive disk 46 to rotate, so that the air blowing head 44 can blow the debris to the upper left drop port 23; similarly; when dynamic coordinate A is located in the upper right / lower left / lower right, the servo motor controls the drive disk 46 to rotate, so that the air blowing head 44 can blow the debris to the upper left drop port 23; The static coordinate B is located at the lower left / upper right / upper left of the dynamic coordinate A; at this time, the air blower 44 can blow the debris to the upper right / lower left / lower right drop port 23. This method allows the air blower 44 to blow the debris into the nearest drop port 23. Furthermore, since the position directly below is the opening 211 of the slot 21, when the air blower 44 blows the debris to the opening 211 of the slot 21, although it will not enter the drop port 23, it will be blocked by the first brush 55 and will not come out from the opening 211 of the slot 21. When the single panel punching is completed and pulled out from the opening 211 of the slot 21, the first brush 55 will clean the debris accumulated on the surface of the single panel, so that the debris enters the collection box 3 from the processing port 22.

[0046] Reference Figure 6 The longitudinal slide 451 is equipped with a dustproof component 6, which includes a dustproof cover 61, a connector 62, and a dustproof elastic element 64. The drill bit 431 of the drilling machine 43 is located inside the dustproof cover 61. One end of the connector 62 has a threaded section, and the other end is fixedly provided with an anti-detachment ring 63; the threaded section is not shown in the figure. The threaded end of the connector 62 passes through the inner wall of the dustproof cover 61 and is connected to and then threaded to the longitudinal slide 451, so that the upper surface of the anti-detachment ring 63 abuts against the upper wall inside the dustproof groove, preventing the dustproof cover 61 from detaching from the connector 62. The dustproof cover 61 can slide relative to the axial direction of the connector 62. The two ends of the dustproof elastic element 64 are respectively fixedly connected to the upper surface of the dustproof cover 61 and the longitudinal slide 451, so that the dustproof cover 61 has elastically compensated movement. In the initial state, the drill bit 431 is located inside the dust cover 61, and the bottom of the dust cover 61 is lower than the bottom of the drill bit 431. When the drill bit 431 moves downward, the dust cover 61 will abut against the upper surface of the processing table 2, and the drill bit 431 will continue to move downward to punch the single panel located at the processing port 22.

[0047] Reference Figure 7 The processing port 22 is connected to the slot 21. After the single panel is inserted into the slot 21 through the insertion port, the position of the single panel that needs to be punched will be exposed at the processing port 22, so that the drill bit 431 can punch holes in the single panel.

[0048] Reference Figure 3 , Figure 7 and Figure 8 A clamping drive unit 58 is provided on the side wall of the processing table 2. A bidirectional threaded rod 51 is provided at the opening 211 of the material discharge port 23 away from the slot 21. The output end of the clamping drive unit 58 is connected to the bidirectional threaded rod 51. In this embodiment, the clamping drive unit 58 is a motor. The bidirectional threaded rod 51 has a forward thread 511 and a reverse thread 512. Positioning plates 52 are threadedly connected to both the forward thread 511 and the reverse thread 512. When the clamping drive unit 58 drives the bidirectional threaded rod 51 to rotate, the two positioning plates 52 will move closer or further away from each other. The positioning plates 52 have a clamping part 53, which extends to the slot 21. After the single panel is inserted into the slot 21, they move closer together to clamp the single panel. The connection position of the forward thread 511 and the reverse thread 512 is exactly located at the Y-axis, so that the positioning plates 52 will also position the single panel after clamping it, keeping the single panel in a centered position. This achieves centering in the Y-axis direction.

[0049] Reference Figure 8 The bidirectional threaded rod 51 is fitted with an abutment block 56, which is located at the connection between the forward thread 511 and the reverse thread 512, so it will not interfere with the movement of the positioning plate 52. When the single panel is pushed into the slot 21, one end of the single panel will abut against the abutment block 56, which can realize the positioning of the single panel on the X-axis.

[0050] The processing table 2 also has a transmission groove 57, which has a first transmission port 578 and a second transmission port 579 communicating with the slot 21. A first transmission block 571 and a second transmission block 572 are slidably disposed in the transmission groove 57. The first transmission block 571 is partially exposed in the first transmission port 578, and the exposed part has an inclined surface facing the opening 211 of the slot 21. The single panel can push the first transmission block 571 into the transmission groove 57 through the inclined surface. A transmission rope 574 is disposed in the slot 21 and fixedly connected to the second transmission block 572. After the first transmission block 571 moves into the transmission groove 57, it will push the transmission rope 574, allowing the transmission rope 572 to move into the slot 21. 4. Pulling the second transmission block 572 also moves it into the transmission groove 57. Part of the second transmission block 572 is exposed in the second transmission port 579. The exposed part is provided with a second brush 573. The second transmission block 572 is fixedly provided with a transmission spring 575. When the single panel moves away from the inclined surface, the transmission spring 575 can force the second transmission block 572 to be exposed in the first transmission port 578. The second transmission port 579 is inclined. When the transmission rope 574 is pulled, it can pull the second transmission block 572. When the transmission rope 574 is not pulled, the second brush 573 is exposed in the second transmission port 579. The slot 21 between the inclined surface and the second brush 573 is the reset area 59.

[0051] In the specific implementation, the inclined surface of the first transmission block 571 and the second brush 573 on the second transmission block 572 are exposed in the first transmission port 578 and the second transmission port 579 respectively in the initial position. After the single panel is inserted into the slot 21, it will push the inclined surface to let the first transmission block 571 enter the transmission groove 57. Under the action of the transmission rope 574, the second transmission block 572 also enters the transmission groove 57. Then the single panel will abut against the abutment block 56, and the clamping part 53 of the positioning plate 52 will clamp the single panel. Then the drilling machine 43 will drill holes in the single panel, and the air blower 44 will blow the debris into the discharge port 23 or the reset area 59. After the punching is completed, the single panel is pulled out. During the pulling process, the single panel will move away from the reset area 59. At this time, the second transmission block 572 will be in the reset position, allowing the second brush 573 to come out from the second transmission port 579. The debris on the upper surface of the single panel and located in the reset area 59 will be hung off by the second brush 573, thereby cleaning the surface of the processed single panel. During the process of pulling the single panel out of the slot 21, the first brush 55 will also clean the surface of the single panel.

[0052] Reference Figure 2 The debris removed during cleaning enters the cleaning chamber through the processing port 22 or the discharge port 23. The cleaning chamber is equipped with a partition plate 31, which divides the interior into a collection chamber 32 and a cleaning chamber 33. The bottom of the collection chamber 321 has a drawer 321 into which debris entering from the processing port 22 and the discharge port 23 falls. The drawer 321 is detachable; in this embodiment, it is disassembled by pulling it out. The cleaning chamber 33 has a cleaning port 331, the opening 211 of which faces the same direction as the opening 211 of the slot 21. The cleaning chamber 33 can be used to simply stack single-panel panels, or it can be filled with cleaning fluid or water for soaking and cleaning the perforated single-panel panels.

[0053] The partition plate 31 is in the shape of "Ren", with the lower part being vertical and used to separate the drawer 321 and the cleaning chamber 33. The upper part is a baffle 311 arranged obliquely. Above the baffle 311, there is an elastic plate 34. One end of the elastic plate 34 is fixedly connected to the top wall of the collection chamber 32. The opening 211 of the slot 21 is located above the elastic plate 34. The first brush 55 scrapes the lint onto the upper surface of the elastic plate 34. Since the upper surface of the elastic plate 34 is also inclined, the debris on the upper surface of the elastic plate 34 can slide into the drawer 321. A polishing channel 35 is formed between the elastic plate 34 and the baffle 311. On the lower surface of the elastic plate 34, which is the position of the upper wall of the polishing channel 35, a polishing strip 351 is fixedly arranged. The polishing strip 351 abuts against the lower surface of the polishing channel 35. When the single-sided board is inserted into the polishing channel 35, it can push the polishing strip 351 to force the elastic plate 34 to elastically deform. In other embodiments, the polishing strip 351 can also be arranged on the bottom wall of the polishing channel 35 or on both the upper wall and the bottom wall simultaneously. The two ends of the polishing channel 35 are respectively a polishing inlet 352 and a polishing outlet 353. The setting direction of the polishing inlet 352 is the same as that of the opening 211 of the slot 21, and the position of the polishing outlet 353 is lower than that of the polishing inlet 352. After the single-sided board is punched, the punched part needs to be polished. At this time, only need to insert the punched single-sided board into the polishing channel 35 through the polishing inlet 352 and insert and pull it back and forth to make the polishing strip 351 rub against the upper surface of the single-sided board. One end of the baffle 311 close to the polishing outlet 353 extends with a guiding part 322. The debris generated by the friction will come out from the polishing inlet 352. Through the guiding of the guiding part 322, the debris generated from the polishing channel 35 can also enter the drawer 321.

[0054] At the bottom of the cleaning chamber 33, there is a rotating plate 332. One end of the rotating plate 332 close to the cleaning port 331 is the rotating end, and the end far from the cleaning port 331 is the free end. The free end of the rotating plate 332 is connected to the end of the elastic plate 34 through a pull rope 333 between the elastic sheet 54. During the polishing of the single-sided board in the polishing channel 35, the elastic plate 34 will elastically deform slightly. Under the action of the pull rope 333, the rotating plate 332 will also turn slightly. The upper surface of the rotating plate 332 is used to prevent the single-sided board that has been punched and polished. In this embodiment, water is filled in the cleaning chamber 33. The slight turning of the rotating plate 332 will make the water flow, which has an effect of flushing and cleaning the single-sided board.

[0055] The implementation principle of this embodiment is as follows: The single-sided board is inserted from the opening 211 of the slot 21 and is fixed under the limitation of the clamping part 53 and the elastic sheet 54. The drilling machine 43 drills holes in the single-sided board from the processing port 22. After the drilling is completed, the single-sided board is pulled out, and then the punched single-sided board is inserted into the polishing channel 35 back and forth for polishing. After the polishing is completed, it is placed on the rotating plate 332 of the cleaning chamber 33.

[0056] A single-sided panel manufacturing process includes the following steps: Step S1: Coating, drying, cooling, and exposing an aluminum substrate to form a circuit pattern, followed by etching to obtain the single-sided panel body; Step S2: Punching the single-sided panel using the aforementioned punching equipment, and then cleaning up the waste generated during punching; Step S3: Testing the single-sided panel after punching using a testing mechanism, and then applying an oil coating; Step S4: Micro-cutting the single-sided panel after applying the oil coating using a micro-cutting mechanism, and then applying an oxide film.

[0057] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
