Description

Technical Field

[0001] This invention relates to the field of circuit board processing technology, and in particular to laser precision processing equipment for FPC high-speed signal transmission lines. Background Technology

[0002] The application of FPC (Flexible Printed Circuit Board) in high-speed signal transmission lines has placed more stringent requirements on the processing quality of the lines. With the increasing demand for high-frequency and high-speed signal transmission, parameters such as the width, spacing, and edge roughness of the conductors must be controlled with high precision. Any slight deviation may lead to a decrease in signal integrity. To meet the high requirements of high-speed signal transmission, traditional chemical etching processes have limitations. Laser processing technology, with its advantages of high precision, non-contact processing, and flexible processing, has become the mainstream process for realizing fine circuit fabrication.

[0003] When laser processing FPC, the material is vaporized or removed, generating processing debris that needs to be cleaned separately later. In addition, the instantaneous high temperature of the laser beam causes the processing area to remain at a high temperature after completion, making it impossible to immediately pick up or transfer the workpiece, thus affecting the continuity of the production process. Therefore, this application proposes a laser precision processing equipment for FPC high-speed signal transmission lines. Summary of the Invention

[0004] The purpose of this invention is to address the problems of difficult debris removal and high temperature of freshly processed FPCs in the prior art, and to propose a laser precision processing device for high-speed signal transmission lines of FPCs.

The drag reduction mechanism, located at the bottom of the motor, is used to reduce the frictional force when the FPC rotates.

[0006] Optionally, the centrifugal mechanism includes a fixed tube, two sets of connecting plates, a vacuum tube, a side rod, a centrifugal ball, a lifting plate, and a transmission tube. The fixed tube is fixed to the outside of the main transmission rod. Both sets of connecting plates are hinged to the outside of the fixed tube. The vacuum tube is hinged to the end of the connecting plate away from the fixed tube. The side rod is slidably connected to the inside of the vacuum tube. The centrifugal ball is fixed to the side rod. The lifting plate is hinged to the end of the side rod away from the centrifugal ball. The transmission tube is fixed to the inside of the lifting plate and slidably connected to the outside of the main transmission rod.

[0007] Optionally, the drag reduction mechanism includes a horizontal plate, an L-shaped rod, a support plate, a connecting shaft, and a slide groove. The horizontal plate is fixed to the top of the transmission tube, and the main transmission rod slides through the horizontal plate. The horizontal plate has a circular design. The L-shaped rod is attached to the bottom end of the horizontal plate. The support plate is fixed to the bottom end of the shelf. The connecting shaft is fixed to the inner wall of the support plate and slides through the L-shaped rod. The slide groove is opened inside the shelf, and the end of the L-shaped rod away from the horizontal plate is located inside the slide groove.

[0008] Optionally, the adsorption mechanism includes an automatic suction cup, a battery, and a controller. The automatic suction cup is fixed to the bottom end of the transmission rod, the battery is installed at the bottom end of the automatic suction cup, the controller is installed on the outside of the frame, and the output end of the controller is connected to the automatic suction cup.

[0009] Optionally, a friction ball is fixed to the end of the L-shaped rod away from the horizontal plate, and the friction ball has a circular cross-section.

[0010] Optionally, an air outlet ring plate is fixed to the outer side of the automatic suction cup, and multiple sets of air outlet holes are opened on the outer side of the air outlet ring plate. A dust removal mechanism is provided at the bottom of the shelf, and the dust removal mechanism is used to blow air onto the surface of the shelf through the air outlet holes.

[0011] Optionally, the dust removal mechanism includes an air pump, an air supply pipe, and an isolation plate. The air pump is installed at the bottom of the support plate, the air supply pipe is drivenly connected to the output end of the air pump, the isolation plate is fixedly connected to the end of the air supply pipe away from the air pump, and the isolation plate is rotatably connected to the inner wall of the air outlet ring plate.

[0012] Optionally, multiple sets of the air outlets are arranged in a uniform circumferential array on the outer side of the air outlet ring plate.

[0013] Optionally, the size of the air outlet ring plate is adapted to the size of the interior of the shelf.

[0014] Optionally, the friction ball is a polyoxymethylene ball.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention uses a centrifugal mechanism to convert the rotational force of the main drive rod into a downward load on the drag-reducing mechanism, which then performs a lifting action to detach the FPC from the shelf. This design achieves automatic suspension of the workpiece during rotation, fundamentally eliminating friction with the shelf and ensuring effective protection of the back of the FPC during high-speed centrifugal cleaning.

[0016] Furthermore, through the structural design of the adsorption mechanism, the FPC is automatically adsorbed and fixed after processing, and the FPC is rotated at high speed. The centrifugal force generated during rotation can effectively remove the processing debris attached to the FPC surface, reducing manual cleaning. At the same time, the air cooling effect generated by rotation can dissipate heat for the workpiece, avoiding difficulties in removing the workpiece due to excessive temperature, thus improving the convenience of operation and processing efficiency.

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 - Figure 4 As shown, the laser precision processing equipment for FPC high-speed signal transmission lines proposed in this invention includes a frame 1. A Z-axis controller 2 is mounted on the top of the frame 1. A laser cutter 3 is mounted on the output end of the Z-axis controller 2. The Z-axis controller 2, as existing technology, can control the height of the laser cutter 3. A Y-axis controller 4 is installed inside the frame 1. An X-axis controller 5 is mounted on the output end of the Y-axis controller 4. The Y-axis controller 4, as existing technology, can control the movement of the X-axis controller 5 along the Y-axis. A support plate 6 is mounted on the output end of the X-axis controller 5. As existing technology, device 5 can control the movement of the support plate 6 along the X-axis and also includes a shelf 7 for placing the FPC. When processing the FPC, the FPC is first placed at the center of the surface of the shelf 7. At this time, the Z-axis controller 2 adjusts the laser cutter 3 to a suitable height along the Z-axis, allowing laser processing of the FPC. Furthermore, the Y-axis controller 4 and X-axis controller 5 can work together, controlling the movement of the FPC via the shelf 7, so that the laser cutter 3 can engrave different positions on the FPC, achieving the function of engraving a path. It should be noted that in this embodiment, the X, Y, and Z axes are... Figure 1The marking direction is the main focus. A motor 9 is fixedly connected inside the shelf 7. The output end of the motor 9 is fixedly connected to the main drive rod 10. After processing, the motor 9 can drive the main drive rod 10 to rotate. A driven rod 11 is slidably connected inside the main drive rod 10. A protrusion 12 is fixedly connected to the outside of the driven rod 11. The protrusion 12 is embedded inside the main drive rod 10. When the main drive rod 10 rotates, it can drive the driven rod 11 to rotate synchronously through the protrusion 12.

[0023] As one implementation method, such as Figure 3 and Figure 4 As shown, the adsorption mechanism in this laser precision processing equipment is connected to the drive rod 11 for automatically adsorbing the FPC. The adsorption mechanism automatically adsorbs and fixes the FPC. When the drive rod 11 rotates, it drives the adsorption mechanism to run. When the adsorption mechanism runs, it can drive the adsorbed FPC to rotate at high speed. When the FPC rotates, centrifugal force is generated, which throws away the debris generated by surface engraving, reducing the operator's workload for cleaning the FPC afterward. In addition, the wind generated during high-speed rotation can also dissipate heat from the FPC surface, thereby avoiding the problem of high temperature making it difficult to remove.

[0024] Furthermore, such as Figure 3 - Figure 7 As shown, the centrifugal mechanism in this laser precision processing equipment is connected to the main drive rod 10 and is used to convert the rotational force of the motor 9 into a vertical force. When the main drive rod 10 rotates, it drives the centrifugal mechanism to run. The drag reduction mechanism is located at the bottom of the motor 9 and is used to reduce the friction force when the FPC rotates. When the centrifugal mechanism runs, it applies downward pressure to the drag reduction mechanism, and the drag reduction mechanism is driven to move the FPC upward. At this time, since the FPC is attracted by the adsorption mechanism, the adsorption mechanism will move upward synchronously when the FPC moves upward. The adsorption mechanism then drives the FPC from the drive rod 11 along the inside of the main drive rod 10. Finally, when the FPC rotates, it will not contact the surface of the shelf 7, thereby avoiding the friction force generated when the FPC rotates and contacts the shelf 7.

[0025] As one implementation method, such as Figure 2 , Figure 3 and Figure 4 As shown, the centrifuge mechanism includes a fixed tube 13, two sets of connecting plates 14, a vacuum tube 15, a side rod 16, a centrifuge ball 17, a lifting plate 18, and a transmission tube 19. The centrifuge mechanism is described in detail below: The fixed tube 13 is fixed to the outside of the main drive rod 10. When the main drive rod 10 rotates, it drives the fixed tube 13 to rotate. Both sets of connecting plates 14 are hinged to the outside of the fixed tube 13. The vacuum tube 15 is hinged to the end of the connecting plate 14 away from the fixed tube 13. When the fixed tube 13 rotates, it drives the vacuum tube 15 to rotate through the connecting plate 14. The side rod 16 is slidably connected to the inside of the vacuum tube 15. When the vacuum tube 15 rotates, it drives the side rod 16 to rotate. The centrifugal ball 17 is fixed to the side rod 16. The side rod 16 will eventually drive the centrifugal ball 17 to rotate. The centrifugal ball 17 rotates in a circular motion around the fixed tube 13. When the centrifugal ball 17 rotates at high speed, it generates centrifugal force, which drives the centrifugal ball 17 to move in an upward direction. The lifting plate 18 is hinged to the side rod 16 at the end away from the centrifugal ball 17. Since the position of the fixed tube 13 is fixed, the centrifugal ball 17 will pull the lifting plate 18 downward through the side rod 16. The transmission tube 19 is fixed inside the lifting plate 18 and slidably connected to the outside of the main transmission rod 10. When the lifting plate 18 moves downward, it will synchronously drive the transmission tube 19 downward. The greater the centrifugal force on the centrifugal ball 17, the farther the lifting plate 18 moves downward. It should be noted that when the side rod 16 swings with the centrifugal ball 17, the vacuum tube 15 can slide along the inside of the side rod 16 to avoid the side rod 16 from getting stuck.

[0026] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, the drag reduction mechanism includes a horizontal plate, an L-shaped rod 20, a support plate 21, a connecting shaft 22, and a sliding groove 23. The drag reduction mechanism is described in detail below: The horizontal plate is fixed to the top end of the transmission tube 19, and the main transmission rod 10 slides through the horizontal plate. When the transmission tube 19 moves downward, it will synchronously drive the horizontal plate downward. The L-shaped rod 20 is in contact with the bottom end of the horizontal plate. When the horizontal plate moves downward, it will apply downward pressure to the L-shaped rod 20. The support plate 21 is fixed to the bottom end of the shelf 7. The connecting shaft 22 is fixed to the inner wall of the support plate 21, and the connecting shaft 22 slides through the L-shaped rod 20. When the L-shaped rod 20 is subjected to force, it will swing along the connecting shaft 22. The sliding groove 23 is opened inside the shelf 7, and the end of the L-shaped rod 20 away from the horizontal plate is located inside the sliding groove 23. The longer end of the L-shaped rod 20 will swing along the inside of the groove 23 toward the top of the shelf 7. During the swinging process, the L-shaped rod 20 will push the FPC upward. The upward movement of the FPC will disengage from the surface of the shelf 7, thereby reducing friction during rotation. It should be noted that the horizontal plate is circular in design, which can ensure that the horizontal plate always applies downward pressure to the L-shaped rod 20 when rotating. Furthermore, the weight of the longer end of the L-shaped rod 20 is greater than the weight of the shorter end. Therefore, after the horizontal plate disengages from applying pressure to the L-shaped rod 20, the L-shaped rod 20 can swing back to its original position under the action of gravity.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, the adsorption mechanism includes an automatic suction cup 24, a battery, and a controller. The adsorption mechanism is described in detail below: The automatic suction cup 24 is fixed to the bottom end of the drive rod 11. The battery is installed at the bottom end of the automatic suction cup 24 and provides power to the automatic suction cup 24. The controller is installed on the outside of the frame 1. The output end of the controller is connected to the automatic suction cup 24. The controller can control the start and stop of the automatic suction cup 24. The controller and the automatic suction cup 24 are wirelessly connected, so there will be no wire harness tangling when the drive rod 11 drives the automatic suction cup 24 to rotate.

[0028] As one implementation method, such as Figure 6 As shown, a friction ball 25 is fixed to one end of the L-shaped rod 20 away from the horizontal plate. The friction ball 25 has a circular cross-section. The friction ball 25 reduces the contact area when in contact with the FPC. The friction ball 25 is a polyoxymethylene ball, which has the characteristics of low coefficient of friction and good self-lubrication. It can effectively reduce the friction generated when the FPC rotates and contacts the friction ball 25.

[0029] Furthermore, such as Figure 8 and Figure 9 As shown, an air outlet ring plate 26 is fixedly connected to the outer side of the automatic suction cup 24. Multiple sets of air outlet holes 27 are formed on the outer side of the air outlet ring plate 26, allowing communication between the outside and the interior of the air outlet ring plate 26. The air outlet ring plate 26 is adapted to the size of the interior of the shelf 7. Because the air outlet ring plate 26 and the shelf 7 are in close contact, in the initial state, the air outlet holes 27 are blocked by the interior of the shelf 7, thus preventing external dust from entering the interior of the air outlet ring plate 26 through the air outlet holes 27. When the automatic suction cup 24 moves upward, the automatic suction cup 24 will simultaneously move the air outlet ring plate 26. As the 6-axis moves upward, the air vent 27 will be exposed. A dust removal mechanism is provided at the bottom of the shelf 7. The dust removal mechanism is used to blow air through the air vent 27 onto the surface of the shelf 7. At this time, the operation of the dust removal mechanism generates airflow inside the air vent ring plate 26. Multiple sets of air vents 27 are evenly arrayed in a circle on the outside of the air vent ring plate 26, and the airflow blows onto the surface of the shelf 7 through the multiple sets of evenly distributed air vents 27, blowing away dust and impurities attached to the surface of the shelf 7, thereby avoiding unevenness caused by dust when the lower FPC contacts the shelf 7.

[0030] Furthermore, such as Figure 7 and Figure 8 As shown, the dust removal mechanism includes an air pump 28, an air supply pipe 29, and an isolation plate 30. The dust removal mechanism is described in detail below: The air pump 28 is installed at the bottom of the support plate 7, which supports the air pump 28. The air supply pipe 29 is connected to the output end of the air pump 28. When the air pump 28 is running, it will deliver gas through the air supply pipe 29. The delivered gas will enter the interior of the air outlet ring plate 26 and be blown onto the surface of the support plate 7 through multiple sets of air outlet holes 27 for dust removal. The isolation plate 30 is fixed to the end of the air supply pipe 29 away from the air pump 28. The isolation plate 30 is rotatably connected to the inner wall of the air outlet ring plate 26. The isolation plate 30 can ensure that it does not affect the normal rotation of the air outlet ring plate 26, and the rubber material of the isolation plate 30 can also seal the bottom end of the air outlet ring plate 26 to prevent gas leakage.

[0031] In this embodiment, the FPC is first placed at the center of the shelf 7. At this time, the Z-axis controller 2 adjusts the laser cutter 3 to a suitable height so that the FPC can be laser-processed. The Y-axis controller 4 and X-axis controller 5 can work together to control the movement of the FPC through the shelf 7. The laser cutter 3 can then engrave different positions of the FPC to achieve the function of engraving the route. The motor 9 can drive the main drive rod 10 to rotate. When the main drive rod 10 rotates, it can drive the secondary drive rod 11 to rotate synchronously through the convex strip 12. The battery provides power to the automatic suction cup 24. The controller can control the start and stop of the automatic suction cup 24. The automatic suction cup 24 adsorbs and fixes the FPC. When the secondary drive rod 11 rotates, it will drive the automatic suction cup 24 to rotate, thereby realizing the rotation of the FPC. When the FPC rotates, centrifugal force is generated, which throws away the debris generated by the surface engraving, reducing the workload of the operator in cleaning the FPC. In addition, the wind generated by the high-speed rotation can also dissipate heat from the FPC surface, thereby avoiding the problem of high temperature making it difficult to remove. Furthermore, when the main drive rod 10 rotates, it drives the fixed tube 13 to rotate. The rotation of the fixed tube 13, in turn, drives the vacuum tube 15 to rotate via the connecting plate 14. The rotation of the vacuum tube 15, in turn, drives the side rod 16 to rotate. The side rod 16 then drives the centrifugal ball 17 to rotate. When the centrifugal ball 17 rotates at high speed, it generates centrifugal force, which drives the centrifugal ball 17 to move in an upward direction. Since the position of the fixed tube 13 is fixed, the centrifugal ball 17 pulls the lifting plate 18 downward via the side rod 16. When the lifting plate 18 moves downward, it simultaneously drives the drive tube 19. As the centrifugal ball 17 moves downward, the greater the centrifugal force on it, the farther the lifting plate 18 moves downward. The rotation of the fixed tube 13 drives the vacuum tube 15 to rotate via the connecting plate 14. The rotation of the vacuum tube 15 then drives the side rod 16 to rotate, which in turn drives the centrifugal ball 17 to rotate. When the centrifugal ball 17 rotates at high speed, it generates centrifugal force, which propels it to move diagonally upward. Since the fixed tube 13 is in a fixed position, the centrifugal ball 17 pulls the lifting plate 18 downward via the side rod 16. As the lifting plate 18 moves downward, it simultaneously drives the transmission tube 19. As the centrifugal force on the centrifugal ball 17 increases, the lifting plate 18 moves further down. The L-shaped rod 20 will swing along the connecting shaft 22 under the force. At this time, the longer end of the L-shaped rod 20 will swing along the inside of the slide groove 23 toward the top of the shelf 7. During the swinging process of the L-shaped rod 20, the L-shaped rod 20 will push the FPC upward. The upward movement of the FPC will cause it to break away from the surface of the shelf 7, thereby reducing friction during rotation. In the initial state, the vent 27 is blocked by the inside of the shelf plate 7, thus preventing external dust from entering the interior of the vent ring plate 26 through the vent 27. When the automatic suction cup 24 moves upward, the automatic suction cup 24 will simultaneously drive the vent ring plate 26 upward, and the vent 27 will be exposed. At this time, the air pump 28 is started. When the air pump 28 is running, it will deliver gas through the air supply pipe 29. The delivered gas will penetrate into the interior of the vent ring plate 26 and be blown onto the surface of the shelf plate 7 through multiple sets of vents 27 for dust removal. The isolation plate 30 can ensure that it does not affect the normal rotation of the vent ring plate 26, and the rubber material of the isolation plate 30 can also seal the bottom of the vent ring plate 26 to prevent gas leakage.

[0032] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
