Description

Technical Field

[0001] This invention relates to the field of integrated circuit technology, specifically to an integrated circuit PCB cutting and fixing bracket. Background Technology

[0002] The integrated circuit PCB cutting fixture is an automated conveying and positioning device used in the precision cutting process of printed circuit boards. Its core components are the conveyor belt and the fixing plate that support and fix the PCB board. Its positioning accuracy and chip removal capability directly affect the cutting quality of the PCB board, the yield rate of finished products, and the continuous operation efficiency of the production line.

[0003] A search revealed that Chinese patent CN211915847U discloses an integrated circuit PCB cutting and fixing frame. This patent, through its structure including a shell, rotating mechanism, top cover, PCB positioning slot, and locking mechanism, achieves rapid fixing and removal of PCBs, reducing operational steps and improving processing efficiency. However, it still has shortcomings in multi-specification PCB production lines and continuous cutting operations: the PCB positioning slot size is fixed, making it impossible to flexibly adjust the positioning range according to different PCB widths, requiring different positioning fixtures for different product models; furthermore, the solution lacks an automatic cleaning and collection mechanism for cutting debris, necessitating manual cleaning by stopping the machine.

[0004] Specifically, on the one hand, the material handling spacing of existing equipment is mostly fixed, which cannot be flexibly adjusted to adapt to PCB boards of different widths and specifications. Changing designs is cumbersome, limiting the equipment's applicability and production efficiency. On the other hand, there is a lack of means to clean cutting debris; ordinary receiving structures lack slag removal functions, leading to debris accumulation and requiring frequent shutdowns for cleaning, thus affecting continuous production. Therefore, an integrated circuit PCB cutting fixture is needed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated circuit PCB cutting fixture, which solves the problems of cumbersome product changeover due to fixed positioning spacing, poor equipment versatility, lack of automatic slag collection and removal, and frequent machine shutdowns for cleaning.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example:

[0042] This invention provides an integrated circuit PCB cutting and fixing bracket, comprising:

[0043] Please see the appendix Figure 1 -Appendix Figure 3 The main frame 1 is equipped with a feeding conveyor belt 2 on the right side and a discharging conveyor belt 3 on the left side. The inner walls of the main frame 1 are provided with two rotating wheels 8 on both sides. The outer walls of the two rotating wheels 8 are fitted with a conveyor belt 14. The fixing plates 6 are arranged at intervals along the outer walls of the conveyor belt 14. The middle of the two rotating wheels 8 on the left side is equipped with a motor-driven drive shaft 10, and the middle of the two rotating wheels 8 on the right side is equipped with a transmission shaft 13 for transmission. The guide frame 12 is installed on the adjacent sides of the two rotating wheels 8. The outer wall of the guide frame 12 is fixedly connected to the main frame 1 through a connecting rod.

[0044] Specifically, the main frame 1 serves as the supporting foundation for the entire PCB cutting fixture. The feeding conveyor belt 2 is mounted on the right side of the main frame 1 to feed the PCB boards to be cut into the loading station. The discharging conveyor belt 3 is mounted on the left side of the main frame 1 to transport the cut PCB boards out of the equipment from the discharging station. After the motor starts, it drives the drive shaft 10 to rotate. The drive shaft 10 drives the two left-side rotating wheels 8 to rotate synchronously. The left-side rotating wheels 8, through the conveyor belt 14, drive the two right-side rotating wheels 8 and the drive shaft 13 to rotate synchronously, thus realizing the cyclical operation of the conveyor belt 14 along the inner wall of the main frame 1. Multiple fixed plates 6 are arranged at intervals on the outer wall. The fixed plates 6 move in a cycle along with the conveyor belt 14, passing through the loading station, processing station and unloading station in sequence. The guide frame 12 is installed on the side close to the left and right rotating wheels 8, that is, between the upper and lower belts of the conveyor belt 14. The guide frame 12 extends along the running direction of the conveyor belt 14. Its outer wall is fixedly connected to the inner wall of the main frame 1 through the connecting rod. The upper surface of the guide frame 12 is connected to the connecting frame roller of the fixed plate 6 to ensure the stability of the fixed plate 6 during operation. At the same time, the guide frame 12 and the fixed plate 6 work together to guide and limit the running trajectory of the conveyor belt 14.

[0045] Please see the appendix Figure 7 and attached Figure 8 Positioning components are slidably connected to both sides of the inner wall of the fixed plate 6. The positioning components include movable seats 28 slidably connected to both sides of the inner wall of the fixed plate 6. Tension springs for resetting are installed between the two ends of the movable seats 28 and the slide grooves of the fixed plate 6. Clamping blocks 32 are fixedly connected to the bottom of both movable seats 28. Positioning plates 29 are installed on both sides of the top of the movable seats 28. A motor-driven bidirectional lead screw is installed on the inner wall of the movable seats 28. The bottom of the positioning plates 29 is sleeved on the outer wall of the bidirectional lead screw through a connecting frame. The spacing of the positioning plates 29 can be automatically adjusted by the motor drive. Positioning blocks 30 are fixedly connected to the ends of the positioning plates 29. The positioning blocks 30 are made of high-temperature resistant and fireproof silicone material, which is used to provide flexible cushioning and prevent high-temperature damage when in contact with the PCB board. Multiple adsorption rods 27 are installed on both sides of the middle part of the fixed plate 6, which are used to fix the PCB board parts by negative pressure adsorption during processing.

[0046] Specifically, the fixing plate 6 is a rectangular frame structure with a positioning cavity in the middle for accommodating the PCB board. When no external force is applied, the tension spring pulls the movable seats 28 to the outside of the fixing plate 6, keeping the movable seats 28 on both sides open, facilitating the placement of the PCB board into the positioning cavity. The bottom end of the second suction rod 27 is equipped with a vacuum suction cup, used to fix the PCB board by negative pressure during processing. Different numbers of suction rods 27 can be installed according to the specifications of the PCB board to be processed. The suction rods 27 firmly adhere the PCB board at the processing station to the fixing plate 6, forming a dual positioning system of clamping and adsorption together with the clamping blocks 32 on both sides, ensuring that the PCB board does not shift during the cutting process.

[0047] According to the PCB board specifications, when the motor drives the bidirectional lead screw to rotate, it causes the two positioning plates 29 to move synchronously in opposite directions, thereby automatically adjusting the distance between the two positioning plates 29 to adapt to PCB boards of different sizes. When the fixed plate 6 moves to the processing station with the conveyor belt 14, the rollers on the outer wall of the clamping block 32 contact the guide rod 35, causing the movable seat 28 to retract, thereby making the positioning block 30 at the end of the positioning plate 29 contact the edge of the PCB board. Utilizing the flexible cushioning properties of the silicone material, rigid contact is used to avoid crushing or chipping the edge of the PCB board. At the same time, the high-temperature resistant and fire-retardant silicone material can withstand the high temperatures generated during the cutting process, preventing the positioning block 30 from deforming or failing due to heat.

[0048] Please see the appendix Figure 2 and attached Figure 8 The fixing plate 6 is fixedly connected to the front and rear sides with connecting blocks 31. The inner wall of the connecting block 31 is provided with a pipe that is connected to the air pipe of the second adsorption rod 27. The main frame 1 is fixedly connected to the front and rear of the fixing box 7. The inner wall of the fixing box 7 is equipped with a docking rod 41 driven by an electric push rod. The end of the docking rod 41 is connected to the connecting block 31 and is used to extend and connect with the connecting block 31 after the fixing plate 6 reaches the processing station, so that the second adsorption rod 27 adsorbs and fixes the PCB board.

[0049] Specifically, the outer end face of the connecting block 31 is provided with a docking air port for docking with the docking rod 41 inside the fixing box 7. When the fixing plate 6 moves to the processing station with the conveyor belt 14, the electric push rod inside the fixing box 7 is activated, pushing the docking rod 41 outward. The end of the docking rod 41 docks with the docking air port of the connecting block 31 and seals it, so that the negative pressure air source is connected to the adsorption rod 27 through the air passage inside the docking rod 41 and the connecting block 31. The vacuum suction cup at the bottom of the adsorption rod 27 generates an adsorption force under the action of negative pressure, firmly adsorbing the PCB board onto the fixing plate 6, forming a double positioning together with the clamping of the clamping blocks 32 on both sides. When the cutting is completed and the fixing plate 6 leaves the processing station with the conveyor belt 14, the electric push rod retracts, the docking rod 41 disengages from the connecting block 31, the negative pressure is disconnected, and the adsorption rod 27 releases the PCB board for subsequent material discharge.

[0050] Please see the appendix Figure 4 and attached Figure 5The mounting plate 4 is fixedly connected to the outer wall of the main frame 1 by connecting rods. The inner wall of the mounting plate 4 is connected to the feeding rack 5 by a reciprocating assembly. The reciprocating assembly includes guide wheels 21 rotatably connected to both sides of the inner wall of the mounting plate 4. A connecting rod 22 is fixedly connected to the middle of each of the two guide wheels 21. The two connecting rods 22 are connected to the feeding rack 5 by connecting rods and brackets, which is used to convert the rotational motion of the guide wheels 21 into the reciprocating translational motion of the feeding rack 5. A rotating shaft 20 is fixedly connected to the inner wall of the guide wheel 21 near the main frame 1. The rotating shaft 20 is connected to the gear shaft 19 by a synchronous belt and synchronous pulley. A half gear 18 is provided on one outer wall of the gear shaft 19. A turntable 17 is provided on the other outer wall of the gear shaft 19. A rotating shaft 16 is fixedly connected to the inner wall of the gear shaft 19. The outer wall of the rotating shaft 16 is fixedly connected to the turntable 17 by a fixed bracket. The end of the right rotating shaft 16 is fixedly connected to the transmission shaft 13, and the end of the left rotating shaft 16 is fixedly connected to the drive shaft 10.

[0051] Specifically, during processing, the drive shaft 10 and transmission shaft 13 drive the left and right rotating shafts 16 to rotate, respectively. The rotating shafts 16 drive the half gear 18 and the turntable 17 to rotate synchronously. When the toothed part of the half gear 18 meshes with the gear on the gear shaft 19, the gear shaft 19 is driven to rotate. Through the synchronous belt and synchronous pulley, it drives the rotating shaft 20 and the guide wheel 21 to rotate. The guide wheel 21 pushes the loading rack 5 to move horizontally in one direction through the connecting rod 22. The guide wheel 21 drives another guide wheel 21 on the same mounting plate 4 to rotate synchronously through the synchronous belt and synchronous pulley, thus forming a parallel linkage structure, which makes the loading rack 5 move horizontally back and forth. When the toothless part of the half gear 18 rotates to the gear shaft 19, the gear shaft 19 loses driving force and stops rotating. The guide wheel 21 stops, and the loading rack 5 stops after reaching the limit position in that direction. Meanwhile, the rotating shaft 16 on the other side drives the corresponding half gear 18 to mesh with another gear shaft 19 in a phase-interleaved state, driving the guide wheel 21 on the other side to rotate in the opposite direction, and driving the loading rack 5 to move in the opposite direction through the connecting rod 22. The half gears 18 on the left and right sides mesh alternately, causing the loading rack 5 to make continuous reciprocating translational movements on the inner wall of the mounting plate 4.

[0052] Please see the appendix Figure 6 Multiple adsorption rods 26 are installed on the inner wall of the feeding rack 5 via a first adjustment component. The first adjustment component includes movable grooves 23 fixedly connected to both sides of the bottom of the feeding rack 5. Threaded rods 24 are rotatably connected to the inner wall of the movable grooves 23. Horizontal rods 25 are slidably connected to both sides of the inner wall of the movable grooves 23. The ends of the horizontal rods 25 are sleeved on the outer wall of the threaded rods 24. The horizontal rods 25 have mounting grooves along their length. The adsorption rods 26 are assembled and fixed in the mounting grooves according to the shape of the PCB board to adapt to PCB boards of different specifications.

[0053] Specifically, the outer wall of the threaded rod 24 is provided with two sections of external threads with opposite directions. The operator can rotate the threaded rod 24 according to the outline and size of the PCB board. The two sections of threads with opposite directions drive the two crossbars 25 to move synchronously towards each other or away from each other along the inner wall of the movable groove 23, thereby adjusting the distance between the two crossbars 25. The position and number of the adsorption rods 26 in the mounting groove can be flexibly adjusted according to the size, so that the adsorption point of the adsorption rods 26 matches the shape of the PCB board, ensuring the stability of adsorption and the uniformity of force. Thus, the loading rack 5 can be adapted to PCB board parts of different specifications, and can complete the loading operation of various products without changing the overall tooling.

[0054] Please see the appendix Figure 9 and attached Figure 10 The support frame 11 is fixedly connected to the inner wall of the middle part of the main frame 1. The middle part of the support frame 11 is connected to the push frame 37 through the second adjustment component, which is used to guide the positioning component to position the PCB board. The second adjustment component includes a moving platform 36 fixedly connected to the middle part of the support frame 11. A motor-driven bidirectional lead screw is installed on the inner wall of the moving platform 36. Push frames 37 are mounted on both sides of the top of the moving platform 36. The distance between the two push frames 37 can be adjusted by rotating the bidirectional lead screw. Guide rods 35 are fixedly connected to the adjacent sides of the two push frames 37. The outer wall of the guide rods 35 can abut against the clamping block 32 that moves to the processing station, thereby positioning the PCB board.

[0055] Specifically, the support frame 11 is located below the upper belt of the conveyor belt 14, corresponding to the position of the processing station. Based on the PCB board dimensions, the starter motor drives the bidirectional lead screw to rotate, driving the two pusher frames 37 to move synchronously towards each other or away from each other along the top of the moving platform 36, thereby adjusting the distance between the two guide rods 35. The guide rods 35 extend horizontally along the running direction of the conveyor belt 14, their height corresponding to the roller positions on the outer walls of the clamping blocks 32 on both sides of the fixed plate 6, and are provided with inclined guide grooves to facilitate the docking of the clamping blocks 32.

[0056] When the fixed plate 6 moves to the processing station with the conveyor belt 14, the rollers on the outer wall of the clamping block 32 contact the guide grooves of the guide rods 35 on both sides. As the fixed plate 6 continues to move forward, the inclined guide grooves of the guide rods 35 push the rollers, causing the movable seat 28 to overcome the elastic force of the tension spring and retract towards the inside of the fixed plate 6. When the movable seat 28 retracts, the clamping block 32 at its bottom clamps the PCB board from both sides. At the same time, the positioning plate 29 at the top of the movable seat 28 moves accordingly, so that the positioning block 30 contacts the edge of the PCB board, completing the positioning of the PCB board. By adjusting the distance between the two pushers 37 by the bidirectional lead screw, the stroke of the guide rod 35 pushing the clamping block 32 can be changed, thereby adapting to PCB boards of different sizes and ensuring that the positioning block 30 contacts the edge of the PCB board in the appropriate position. The PCB board can be processed by a three-axis laser cutting machine, which is existing technology and will not be described in detail here.

[0057] Please see the appendix Figure 9 Appendix Figure 11 and attached Figure 12 The collection plate 15 is mounted on the top of the support frame 11 via a bracket. The top of the collection plate 15 is connected to a vibrating plate 39 via a cam assembly. The cam assembly includes the vibrating plate 39, which is slidably connected to the top of the collection plate 15. A vibrating rod 40 is fixedly connected to the bottom of the vibrating plate 39. A cam block 38 is abutted against the bottom of the vibrating rod 40. A spring for resetting is sleeved on the outer wall of the vibrating rod 40. A rotating shaft 34 is fixedly connected to the outer periphery of the cam block 38. A reversing shaft 33 is driven to the outer wall of the transmission shaft 13 via a synchronous pulley and synchronous belt. The end of the reversing shaft 33 is fixed to the inner wall of the guide frame 12 via a bracket. The reversing shaft 33 is driven to the rotating shaft 34 via two meshing bevel gears. A collection box 9 for collecting debris is fixedly connected to the output end of the collection plate 15.

[0058] Specifically, the collecting plate 15 is fixedly installed on top of the support frame 11 via a bracket, located below the processing station, to collect debris generated during PCB board cutting. During operation, the drive shaft 13 rotates, driving the reversing shaft 33 to rotate via a synchronous pulley and belt. The reversing shaft 33 drives the rotating shaft 34 to rotate synchronously via a bevel gear set, which in turn drives the cam block 38 to rotate. The protruding part of the cam block 38 periodically pushes the bottom of the vibrating rod 40, causing it to move upwards. The vibrating rod 40 drives the vibrating plate 39 to slide upwards along the top of the collecting plate 15, compressing the spring. When the protruding part of the cam block 38 moves away from the vibrating rod 40, the spring force pushes the vibrating rod 40 and the vibrating plate 39 downwards to reset. The cam block 38 continues to rotate, and the vibrating plate 39 continuously vibrates up and down on the top of the collecting plate 15. The debris falling onto the collecting plate 15 moves towards the output end along the surface of the collecting plate 15 under the vibration of the vibrating plate 39. The debris eventually falls from the output end of the collection plate 15 into the collection box 9 for centralized collection. The collection box 9 can be periodically removed from the output end of the collection plate 15 to empty and clean the debris inside.

[0059] Working principle:

[0060] Before starting the equipment, the operator pre-adjusts each actuator according to the size and specifications of the PCB board to be processed. First, the fixed frame is adjusted to adapt to the specifications of the PCB board. The operator rotates the adjusting end of the threaded rod on the inner wall of the loading rack, and the crossbar slides along the movable groove to adjust the distance between the two crossbars. Then, the first suction rod is assembled and fixed in the mounting groove of the crossbar according to the shape of the PCB board, so that the suction point of the first suction rod matches the shape of the PCB board. Next, according to the size of the PCB board, the spacing of the positioning plates of the positioning component in the fixed plate is adjusted. The motor on the inner wall of the movable seat drives the bidirectional lead screw to rotate. The threaded sections on the left and right sides of the bidirectional lead screw rotate in opposite directions, driving the two positioning plates to move synchronously in opposite directions, thereby adjusting the distance between the two positioning plates to adapt to PCB boards of different sizes and specifications. At the same time, different numbers of second suction rods are installed according to the specifications of the PCB board. Then, based on the width of the PCB board, adjust the spacing between the pushers of the second adjustment component in the middle of the support frame, start the motor on the inner wall of the moving platform to drive the bidirectional lead screw to rotate, drive the two pushers to move synchronously towards each other or away from each other along the top of the moving platform, thereby adjusting the spacing between the two guide rods to accommodate PCB boards of different sizes.

[0061] The motor drives the drive shaft to rotate, which in turn drives the two left-side rollers to rotate synchronously. These left-side rollers, via the conveyor belt, drive the two right-side rollers and the drive shaft to rotate synchronously. The conveyor belt circulates along the rollers on the inner wall of the main frame. Multiple fixed plates are spaced along the outer wall of the conveyor belt, sequentially passing through the loading, processing, and unloading stations to form a continuous production cycle. The guide frame is located below the upper layer of the conveyor belt, providing central support and guidance to prevent sagging or deviation.

[0062] The feeding conveyor belt delivers the PCB boards to be cut into the loading station on the right side of the main frame. The drive shaft and transmission shaft drive the rotating shafts on the left and right sides to rotate, respectively. The rotating shafts drive the half gears and turntable to rotate synchronously. The half gears on the left and right sides alternately mesh with the corresponding gear shafts in a staggered phase state. The gear shafts drive the rotating shaft and guide wheel to perform periodic forward and reverse rotation through the synchronous belt and synchronous pulley. The guide wheel converts the rotational motion into the semi-circular reciprocating translational motion of the loading rack through the connecting rod. The loading rack uses the suction rod to pick up the PCB boards on the feeding conveyor belt, and then translates along the semi-circular trajectory to the top of the fixed plate on the conveyor belt, placing the PCB boards into the positioning cavity of the fixed plate.

[0063] After the PCB board is placed on the fixing plate, the movable seats on both sides of the inner wall of the fixing plate remain open under the action of tension springs, facilitating the entry of the PCB board. When the fixing plate moves to the processing station with the conveyor belt, the rollers on the outer wall of the clamping block contact the guide rod of the second adjustment component in the middle of the support frame. The inclined guide groove of the guide rod pushes the roller, causing the movable seat to overcome the elastic force of the tension spring and retract towards the inside of the fixing plate. The clamping block at the bottom of the movable seat clamps the PCB board from both sides, and at the same time, the positioning plate at the top of the movable seat moves accordingly, so that the positioning block contacts the edge of the PCB board. The positioning block is made of high-temperature resistant and fire-retardant silicone material, providing flexible cushioning and preventing high-temperature damage. Meanwhile, the electric push rod in the front and rear fixing boxes in the middle of the main frame drives the docking rod to extend. The end of the docking rod docks with the connecting blocks on the front and rear sides of the fixing plate and connects to negative pressure. The negative pressure is transmitted to the second adsorption rod through the air passage inside the connecting block. The vacuum suction cup at the bottom of the second adsorption rod firmly adsorbs the PCB board onto the fixing plate. The clamping of the clamping block and the adsorption of the second adsorption rod together form a double positioning, ensuring that the PCB board does not shift during the cutting process.

[0064] After the PCB board is cut at the processing station, the resulting debris falls onto a collection plate on top of the support frame. The drive shaft, via a synchronous pulley and belt, drives a reversing shaft to rotate. This reversing shaft, through two meshing bevel gears, drives a rotating shaft three to rotate. The rotating shaft three drives a cam block to rotate. The protruding part of the cam block periodically pushes against the bottom of the vibrating rod, causing it to move upwards. The vibrating rod then drives a vibrating plate to slide upwards along the top of the collection plate, compressing the spring. When the protruding part of the cam block moves away from the vibrating rod, the spring force pushes the vibrating rod and vibrating plate downwards to reset. The cam block continues to rotate, and the vibrating plate continuously vibrates up and down on top of the collection plate. The debris falling onto the collection plate moves along its surface towards the output end under the influence of vibration, eventually falling into the collection box for collection.

[0065] After cutting, the fixing plate moves to the unloading station with the conveyor belt. The electric push rod inside the fixing box retracts, the connecting rod disengages from the connecting block, the negative pressure is broken, the second suction rod releases the PCB board, and the movable seat resets outward under the action of the tension spring. The unloading conveyor belt delivers the cut PCB board to the unloading station, where it is sent from the loading rack on the left to the unloading conveyor belt. The empty fixing plate returns to the loading station with the conveyor belt, waiting for the next PCB board. Each actuator works in a fixed cycle, realizing continuous automated cutting production of PCB boards.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
