Description

Technical Field

[0001] This application relates to the field of flexible circuit board punching, and in particular to a flexible circuit board punching device that facilitates waste collection. Background Technology

[0002] Flexible printed circuit boards, also known as flexible circuit boards, flexible circuit boards, or flexible boards, are a special type of printed circuit board. They are characterized by their light weight, thinness, flexibility, and bendability, and are mainly used in many products such as mobile phones, laptops, PDAs, digital cameras, and LCD screens.

[0003] The structure of a flexible printed circuit board (PCB) generally consists of a substrate, copper foil, adhesive, protective film, and reinforcement. The substrate used to produce PCBs is usually made of flexible polyimide material. In the early stages of production, corresponding holes are usually made on the substrate according to the needs of the PCB. The substrate is then divided for subsequent production and assembly. The corresponding holes are evenly made on the substrate, and a punching machine is generally used for punching. The basic structure of the punching machine is that a corresponding punching head is fixed on a punching plate, and a corresponding punching head is made on another punching plate. The substrate is placed between the two punching plates, and the punching head enters the punching groove to complete the punching.

[0004] When a punching machine impacts a substrate, the rolled substrates are passed sequentially through the punching area of ​​the punching machine. The punching head punches the substrates as they pass through, and the substrate waste is usually discharged directly from the punching groove. The waste is either directly piled up or scattered under the punching plate. Over time, the waste may accumulate in the punching groove, affecting normal operation and making cleaning more troublesome. Summary of the Invention

[0005] The purpose of this application is to solve the problem mentioned in the background art that the punching head punches the substrate, and the substrate waste is generally directly leaked out from the punching groove, and the waste is directly accumulated or scattered under the punching plate. Long-term accumulation may cause the waste to accumulate in the punching groove, affecting normal operation, and cleaning is also troublesome. This application provides a flexible circuit board punching device that facilitates the collection of waste.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution: A flexible circuit board punching device for convenient waste collection includes a punching worktable, a punching plate one fixed on the punching worktable, a punching plate two disposed on the punching plate one, a punching hydraulic telescopic rod fixed on the punching worktable, the telescopic end of the punching hydraulic telescopic rod being fixedly connected to the punching plate two, a punching plate one having uniformly distributed punching grooves penetrating the punching plate one, a punching plate two having uniformly distributed punching heads fixed on the punching plate two, a collection mechanism disposed between the punching plate one and the punching worktable, a cleaning mechanism disposed on one side of the punching plate one, a support roller mounted on one side of the punching worktable, a collection roller mounted on the side of the punching worktable away from the support roller, two symmetrical spring telescopic rods fixed on the punching plate two, a clamping plate fixed between the two spring telescopic rods, and a controller mounted on the punching worktable.

[0007] By adopting the above technical solution, the waste material punched off the flexible printed circuit board enters the punching groove. The collection mechanism between the punching plate and the punching worktable moves the punched waste material and then collects it uniformly. During the collection process, the collection mechanism drives the cleaning mechanism, which moves and cleans the punched waste material on the collection mechanism, allowing it to detach from the collection mechanism. This facilitates the uniform collection and processing of the punched waste material from the flexible printed circuit board, reducing the possibility of the punched waste material affecting the normal punching of the flexible printed circuit board. At the same time, it allows the cleaning mechanism to clean the waste material on the collection mechanism, reducing the possibility of waste material adhering to the collection mechanism and affecting its normal waste collection.

[0008] Furthermore, the collection mechanism includes two collection support shafts disposed at the bottom of a punching plate. One of the collection support shafts is rotatably connected to the punching worktable at both ends, and the other collection support shaft is rotatably connected to a support plate at both ends. The two support plates are fixedly connected to the punching worktable. A collection conveyor belt is driven between the two collection support shafts. A collection drive motor is fixed on one of the support plates. The output end of the collection drive motor passes through the support plate and is fixedly connected to the collection support shaft. A collection box is fixed on the side of the punching worktable near the support plate. A moving component is disposed inside the collection box. A scraping component is disposed on the collection conveyor belt.

[0009] By adopting the above technical solution, the controller controls the rotation of the collection drive motor, which drives one of the collection support shafts to rotate. With the support of the other collection support shaft, the collection conveyor belt moves towards the collection box. The waste material entering the punching slot is moved onto the collection conveyor belt by the scraping component. Then, the collection conveyor belt moves the waste material towards the collection box. When the waste material reaches the end of the collection conveyor belt, it falls from the collection conveyor belt into the collection box. This makes it easy to collect the waste material generated from punching flexible printed circuit boards, reduces the possibility of waste material accumulating in the punching slot, and also reduces the possibility of waste material scattering on the punching worktable and being inconvenient to clean.

[0010] Furthermore, the moving component includes two movable support shafts rotatably connected within the collection box, a movable conveyor belt drivingly connecting the two movable support shafts, a movable drive motor fixed to one side of the collection box, the output end of the movable drive motor passing through the collection box and fixedly connected to one of the movable support shafts, and a laser sensor fixed on the inner wall of the collection box near the opening.

[0011] By adopting the above technical solution, when the height of the accumulated waste blocks the laser sensor, the mobile drive motor drives one of the mobile support shafts to rotate back and forth, causing the mobile conveyor belt to move back and forth under the support of the other mobile support shaft. This allows the accumulated waste to be spread on the mobile conveyor belt, thereby reducing waste accumulation when the collection box collects waste and affecting the possibility of waste falling off the collection conveyor belt.

[0012] Furthermore, two symmetrical inclined baffles are fixed inside the collection box, and the two inclined baffles are located at both ends of the moving conveyor belt.

[0013] By adopting the above technical solution, the inclined baffle fixed inside the collection box blocks both ends of the moving conveyor belt, keeping the waste outside the gap between the moving conveyor belt and the inner wall of the collection box. This reduces the possibility of waste entering the gap between the moving conveyor belt and the collection box and affecting the normal movement of the moving conveyor belt.

[0014] Furthermore, the scraping assembly includes several rubber heads that are uniformly fixed on the collection conveyor belt. The rubber heads are hemispherical. The first punching plate has several limiting inclined surfaces that correspond to the punching grooves on the first punching plate.

[0015] By adopting the above technical solution, the contact rubber head passes by one side of the punching head, and then, under the push of the contact rubber head and the limitation of the limiting inclined surface, the punched waste material comes into contact with the collection conveyor belt, thereby enabling the punched waste material to separate from the punching head, reducing the possibility of waste material adhering to the punching head, and at the same time reducing the possibility of waste material slipping on the collection conveyor belt.

[0016] Furthermore, the cleaning mechanism includes a cleaning rod disposed between two support plates, with both ends of the cleaning rod rotatably connected to the corresponding support plates, and a plurality of cleaning blades evenly distributed in a circle fixed on the cleaning rod, and a speed-changing synchronization component disposed at one end of the cleaning rod.

[0017] By adopting the above technical solution, when the collection support shaft rotates, the collection support shaft drives the sweeping bar to rotate using the speed-changing synchronization component. The sweeping blades on the sweeping bar come into contact with the collection conveyor belt. When the sweeping bar rotates, the sweeping blades on the sweeping bar sweep the collection conveyor belt, thereby enabling the sweeping blades on the sweeping bar to sweep the waste on the collection conveyor belt, reducing the possibility of waste adhering to the collection conveyor belt and affecting the normal operation of the collection conveyor belt.

[0018] Furthermore, the speed-changing synchronization assembly includes a first speed-changing gear fixed on one of the support plates, one end of the collecting support shaft passing through the corresponding support plate and fixedly connected to the first speed-changing gear, a second speed-changing gear being provided on one side of the first speed-changing gear, the first speed-changing gear meshing with the first speed-changing gear, the second speed-changing gear being rotatably connected to the support plate, and one end of the sweeping rod passing through the support plate and fixedly connected to the second speed-changing gear.

[0019] By adopting the above technical solution, the diameter of the first gear is larger than that of the second gear, and the rotation speed of the second gear is faster than that of the first gear. This allows the second gear to drive the sweeping bar, and the rotation speed of the sweeping bar is faster than that of the collection support shaft. This allows the sweeping blades on the sweeping bar to quickly sweep across the collection conveyor belt, reducing the possibility of waste adhering to the collection conveyor belt.

[0020] Furthermore, the cleaning blade is a rubber sheet, and the cleaning blade is arc-shaped with the arc facing the direction of rotation of the cleaning rod.

[0021] By adopting the above technical solution, the sweeping bar drives the sweeping blade to contact the collection conveyor belt, thereby reducing the wear of the sweeping blade on the collection conveyor belt and making it easier for the end of the sweeping blade to contact the collection conveyor belt.

[0022] In summary, this application includes at least one of the following beneficial effects; 1. In this application, after the punching head on the second punching plate enters the punching groove on the first punching plate, the flexible printed circuit waste material punched off is flushed into the punching groove. Then, the controller controls the collection drive motor to rotate, which drives one of the collection support shafts to rotate. With the support of the other collection support shaft, the collection conveyor belt moves towards the collection box. The waste material entering the punching groove is moved onto the collection conveyor belt by the scraping component. Then, the collection conveyor belt moves the waste material towards the collection box. When the waste material reaches the end of the collection conveyor belt, it falls from the collection conveyor belt into the collection box. The punched waste material accumulates in the collection box. When the waste material accumulates too high in the collection box, the moving component flattens the waste material in the collection box, allowing the collection box to collect more waste material at once. This achieves the purpose of conveniently collecting the waste material generated from punching flexible printed circuit boards, reducing the possibility of waste material accumulating in the punching groove, and reducing the possibility of waste material scattering on the punching worktable and being inconvenient to clean.

[0023] 2. In this application, while the collection support shaft rotates, the collection support shaft drives the speed-changing synchronization component. The speed-changing synchronization component makes the sweeping bar and the collection support shaft rotate synchronously, while the sweeping bar rotates faster than the collection support shaft. The sweeping blades on the sweeping bar come into contact with the collection conveyor belt. When the sweeping bar rotates, the sweeping blades on the sweeping bar sweep the collection conveyor belt, allowing the waste on the collection conveyor belt to be removed from the collection conveyor belt more quickly. At the same time, the waste falls from between the sweeping bar and the collection conveyor belt into the collection box. This achieves the purpose of enabling the sweeping blades on the sweeping bar to sweep the waste on the collection conveyor belt, reducing the amount of waste adhering to the collection conveyor belt, further improving the convenience of waste collection, and reducing the possibility of affecting the normal operation of the collection conveyor belt.

[0024] 3. In this application, as the collecting conveyor belt moves under the support of two collecting support shafts, the collecting conveyor belt drives the abutting rubber head to move. When the punching head on the second punching plate enters the punching groove in the first punching plate, the abutting rubber head passes by one side of the punching head. Then, the abutting head pushes the waste material punched off by the punching head towards the direction of the limiting slope. Then, under the push of the abutting rubber head and the limitation of the limiting slope, the punched waste material abuts against the collecting conveyor belt and is then carried away by the collecting conveyor belt. This achieves the purpose of separating the punched waste material from the punching head, reducing the possibility of waste material adhering to the punching head, and at the same time reducing the possibility of waste material slipping on the collecting conveyor belt.

[0027] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0028] This application discloses a flexible circuit board punching device that facilitates the collection of waste materials.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A flexible circuit board punching device for convenient waste collection includes a punching worktable 1, a punching plate 2 fixed on the punching worktable 1, a punching plate 3 on the punching plate 2, a punching hydraulic telescopic rod 4 fixed on the punching worktable 1, the telescopic end of the punching hydraulic telescopic rod 4 being fixedly connected to the punching plate 3, a punching plate 2 having uniformly distributed punching grooves that penetrate the punching plate 2, a punching head fixed on the punching plate 3 having uniformly distributed punching heads, a collection mechanism 5 between the punching plate 2 and the punching worktable 1, a cleaning mechanism 6 on one side of the punching plate 2, a support roller 7 installed on one side of the punching worktable 1, a collection roller 8 installed on the side of the punching worktable 1 away from the support roller 7, two symmetrical spring telescopic rods 10 fixed on the punching plate 3, a clamping plate 9 fixed between the two spring telescopic rods 10, and a controller 11 installed on the punching worktable 1.

[0030] When the punching device is needed, the rolled flexible printed circuit board is first placed onto the support roller 7. Then, the end of the flexible printed circuit board is passed between the first punching plate 2 and the second punching plate 3, and then fixedly connected to the collecting roller 8. Then, the controller 11 controls the punching hydraulic telescopic rod 4 to bring the second punching plate 3, along with the punching head, closer to the first punching plate 2. When the second punching plate 3 approaches the first punching plate 2, the clamping plate 9, supported by the spring telescopic rod 10, abuts against the flexible printed circuit board on the first punching plate 2. Then, the second punching plate 3 continues... The plate continues to descend, allowing the punching head on the second punching plate 3 to enter the punching groove on the first punching plate 2, punching an opening on the flexible printed circuit board corresponding to the punching head. Then, the second punching plate 3 and the clamping plate 9 are reset, and the collecting roller 8 moves the punched flexible printed circuit board away from between the first punching plate 2 and the second punching plate 3, allowing the unpunched flexible printed circuit board to move between the first punching plate 2 and the second punching plate 3. Then, punching is performed again. When the punching head on the second punching plate 3 enters the punching groove on the first punching plate 2, the flexible printed circuit board is punched out. The cut waste material enters the punching groove. The collecting mechanism 5 between the punching plate 2 and the punching worktable 1 moves the cut waste material and collects it uniformly. During the collection process, the collecting mechanism 5 drives the cleaning mechanism 6, which moves and cleans the cut waste material on the collecting mechanism 5, allowing it to detach from the collecting mechanism 5. By using the punching plate 2 and the punching plate 3 to punch the flexible printed circuit board, the collecting mechanism 5 is used to collect the cut waste material. The incoming waste is collected uniformly. At the same time, the collection mechanism 5 drives the cleaning mechanism 6 to clean the waste on the collection mechanism 5, allowing the waste to detach from the collection mechanism 5. This facilitates the unified collection and processing of the waste from the punched flexible printed circuit boards, reducing the possibility of the punched waste affecting the normal punching of flexible printed circuit boards. At the same time, the cleaning mechanism 6 cleans the waste on the collection mechanism 5, reducing the possibility of waste adhering to the collection mechanism 5 and affecting the normal collection of waste.

[0031] Reference Figure 1 , Figure 2 and Figure 3The collection mechanism 5 includes two collection support shafts 51 disposed at the bottom of the punching plate 2. One collection support shaft 51 is rotatably connected to the punching worktable 1 at both ends, and the other collection support shaft 51 is rotatably connected to support plates 57 at both ends. The two support plates 57 are fixedly connected to the punching worktable 1. A collection conveyor belt 52 is connected between the two collection support shafts 51. A collection drive motor 53 is fixed on one of the support plates 57. The output end of the collection drive motor 53 passes through the support plate 57 and is fixedly connected to the collection support shaft 51. A collection box 54 is fixed on the side of the punching worktable 1 near the support plate 57. A moving component 55 is disposed inside the collection box 54. A scraping component 56 is disposed on the collection conveyor belt 52.

[0032] After the punching head on the second punching plate 3 enters the punching groove on the first punching plate 2, the flexible printed circuit waste that is punched off is flushed into the punching groove. Then, the controller 11 controls the collection drive motor 53 to rotate. The collection drive motor 53 drives one of the collection support shafts 51 to rotate. With the support of the other collection support shaft 51, the collection conveyor belt 52 moves towards the collection box 54. The waste that has entered the punching groove is moved onto the collection conveyor belt 52 by the scraping component 56. Then, the collection conveyor belt 52 moves the waste towards the collection box 54. When the waste reaches the end of the collection conveyor belt 52, the waste is discharged from the collection conveyor belt. The waste material falls from the conveyor belt 52 into the collection box 54. The waste material is accumulated in the collection box 54. When the waste material is too high in the collection box 54, the moving component 55 is used to flatten the waste material in the collection box 54, so that the collection box 54 can collect more waste material at a time. By dropping the waste material entering the punching groove directly onto the collection conveyor belt 52, and then being driven by the collection conveyor belt 52, the waste material is moved into the collection box 54. This makes it easier to collect the waste material generated from punching flexible printed circuit boards, reduces the possibility of waste material accumulating in the punching groove, and also reduces the possibility of waste material being scattered on the punching worktable 1 and making it inconvenient to clean.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The moving component 55 includes two moving support shafts 554 rotatably connected within the collection box 54. A moving conveyor belt 551 is driven between the two moving support shafts 554. A moving drive motor 552 is fixed on one side of the collection box 54. The output end of the moving drive motor 552 passes through the collection box 54 and is fixedly connected to one of the moving support shafts 554. A laser sensor 553 is fixed on the inner wall of the collection box 54 near the opening.

[0034] The waste material cut off falls from the collection conveyor belt 52 into the collection box 54. The waste material accumulates in the collection box 54 on the side near the collection conveyor belt 52. When the height of the waste material accumulation blocks the laser sensor 553, the controller 11 controls the mobile drive motor 552 to rotate back and forth. The mobile drive motor 552 drives one of the mobile support shafts 554 to rotate back and forth, causing the mobile conveyor belt 551 to move back and forth supported by the other mobile support shaft 554. The waste material accumulated on the mobile conveyor belt 551 is moved back and forth by the mobile conveyor belt 551. Then, the accumulated waste material is spread on the mobile conveyor belt 551 by the movement of the mobile conveyor belt 551. By using the movement of the mobile conveyor belt 551 to spread the accumulated waste material on the mobile conveyor belt 551 when the waste material accumulates too high on one side of the collection box 54, the accumulation of waste material can be reduced when the collection box 54 collects waste material, thus affecting the possibility of waste material falling from the collection conveyor belt 52.

[0035] Reference Figure 2 and Figure 3 Two symmetrical inclined baffles 555 are fixed inside the collection box 54, located at both ends of the moving conveyor belt 551. As the moving conveyor belt 551 moves back and forth, it carries the waste material back and forth. The inclined baffles 555 inside the collection box 54 block both ends of the moving conveyor belt 551, preventing the waste material from entering the gap between the moving conveyor belt 551 and the inner wall of the collection box 54. By using the inclined baffles 555 to block the waste material, the possibility of waste material entering the gap between the moving conveyor belt 551 and the collection box 54 and affecting the normal movement of the moving conveyor belt 551 can be reduced.

[0036] Reference Figure 2 and Figure 4 The scraping component 56 includes several rubber heads 561 that are uniformly fixed on the collection conveyor belt 52. The rubber heads 561 are hemispherical. The punching plate 2 has several limiting inclined surfaces 562 that are opened to abut against it. The limiting inclined surfaces 562 correspond to the punching grooves on the punching plate 2.

[0037] As the collecting conveyor belt 52 moves under the support of the two collecting support shafts 51, it drives the contact rubber head 561 to move. When the punching head on the second punching plate 3 enters the punching groove in the first punching plate 2, the contact rubber head 561 passes by one side of the punching head. Then, the contact head pushes the waste material punched off by the punching head towards the limiting inclined surface 562. Then, under the push of the contact rubber head 561 and the limiting of the limiting inclined surface 562, the punched waste material comes into contact with the collecting conveyor belt 52 and is then carried away by the collecting conveyor belt 52. By having the collecting conveyor belt 52 drive the contact rubber head 561, the contact rubber head 561 pushes the waste material on the punching head, thereby allowing the punched waste material to separate from the punching head, reducing the possibility of waste material adhering to the punching head, and at the same time reducing the possibility of waste material slipping on the collecting conveyor belt 52.

[0038] Reference Figure 1 , Figure 2 and Figure 5 The cleaning mechanism 6 includes a cleaning rod 61 disposed between two support plates 57. The two ends of the cleaning rod 61 are rotatably connected to the corresponding support plates 57. Several cleaning blades 62 are fixed on the cleaning rod 61 and are evenly distributed in a circle. A speed-changing synchronization component 63 is provided at one end of the cleaning rod 61.

[0039] When the collection support shaft 51 rotates, it drives the speed-changing synchronization component 63. The speed-changing synchronization component 63 makes the sweeping bar 61 and the collection support shaft 51 rotate synchronously, while the sweeping bar 61 rotates faster than the collection support shaft 51. The sweeping blades 62 on the sweeping bar 61 come into contact with the collection conveyor belt 52. When the sweeping bar 61 rotates, the sweeping blades 62 on the sweeping bar 61 sweep the collection conveyor belt 52, allowing the waste on the collection conveyor belt 52 to be removed from the collection conveyor belt 52 more quickly. At the same time, the waste falls from between the sweeping bar 61 and the collection conveyor belt 52 into the collection box 54. By making the collection support shaft 51 rotate while the collection support shaft 51 rotates, and the speed-changing synchronization component 63 drives the sweeping bar 61 to rotate, the sweeping blades 62 on the sweeping bar 61 can sweep the waste on the collection conveyor belt 52, reducing the possibility of waste adhering to the collection conveyor belt 52 and affecting the normal operation of the collection conveyor belt 52.

[0040] Reference Figure 1 and Figure 5 The speed-changing synchronization assembly 63 includes a first speed-changing gear 631 fixed on one of the support plates 57. One end of the collecting support shaft 51 passes through the corresponding support plate 57 and is fixedly connected to the first speed-changing gear 631. A second speed-changing gear 632 is provided on one side of the first speed-changing gear 631. The first speed-changing gear 631 meshes with the first speed-changing gear 631. The second speed-changing gear 632 is rotatably connected to the support plate 57. One end of the cleaning rod 61 passes through the support plate 57 and is fixedly connected to the second speed-changing gear 632.

[0041] When the collection drive motor 53 drives the collection support shaft 51 to rotate, the collection support shaft 51 drives the first speed-changing gear 631 to rotate, which in turn drives the second speed-changing gear 632 to rotate. The diameter of the first speed-changing gear 631 is larger than that of the second speed-changing gear 632, and the rotation speed of the second speed-changing gear 632 is faster than that of the first speed-changing gear 631. This causes the second speed-changing gear 632 to drive the sweeping rod 61, and the rotation speed of the sweeping rod 61 is faster than that of the collection support shaft 51, thus enabling the sweeping rod 61 to rotate. The cleaning blade 62 on the rod 61 can move faster than the collection conveyor belt 52, allowing the cleaning blade 62 to move the waste on the collection conveyor belt 52. By driving the collection support shaft 51 to drive the first gear 631, the first gear 631 drives the second gear 632, which in turn drives the cleaning rod 61 to rotate faster. This allows the cleaning blade 62 on the cleaning rod 61 to quickly sweep across the collection conveyor belt 52, reducing the possibility of waste adhering to the collection conveyor belt 52.

[0042] Reference Figure 1 and Figure 5 The cleaning blade 62 is made of rubber and is arc-shaped, with the arc facing the direction of rotation of the cleaning rod 61. When the cleaning rod 61 rotates, it causes the cleaning blade 62 to contact the collection conveyor belt 52. The cleaning rod 61 pushes the waste on the collection conveyor belt 52, and the arc shape of the cleaning blade 62 makes it easier for its end to push the waste on the collection conveyor belt 52. By making the cleaning blade 62 a rubber sheet and arc-shaped, it is possible to make the cleaning blade 62 contact the collection conveyor belt 52, reducing wear on the belt and making it easier for its end to contact the belt.

[0043] Working principle: When the punching device is needed, the rolled flexible printed circuit board is first placed on the support roller 7. Then, the end of the flexible printed circuit board passes between the first punching plate 2 and the second punching plate 3, and is fixedly connected to the collecting roller 8. Then, the controller 11 controls the punching hydraulic telescopic rod 4 to bring the second punching plate 3, along with the punching head, closer to the first punching plate 2. When the second punching plate 3 approaches the first punching plate 2, the clamping plate 9, supported by the spring telescopic rod 10, abuts against the flexible printed circuit board on the first punching plate 2. Then, the second punching plate 3 continues to descend, allowing the punching head on the second punching plate 3 to enter the punching groove on the first punching plate 2, punching an opening on the flexible printed circuit board corresponding to the punching head. After the punching head on the second punching plate 3 enters the punching groove on the first punching plate 2, the punched-off flexible printed circuit waste is flushed into the punching plate 2. Inside the cutting groove, the controller 11 controls the collection drive motor 53 to rotate. The collection drive motor 53 drives one of the collection support shafts 51 to rotate. With the support of the other collection support shaft 51, the collection conveyor belt 52 moves towards the collection box 54. The collection conveyor belt 52 drives the contact rubber head 561 to move. When the punching head on the second punching plate 3 enters the punching groove in the first punching plate 2, the contact rubber head 561 passes by one side of the punching head. Then the contact head pushes the waste material punched off by the punching head towards the limiting inclined surface 562. Then, under the push of the contact rubber head 561 and the limiting inclined surface 562, the punched waste material abuts against the collection conveyor belt 52 and is then carried away by the collection conveyor belt 52. When the waste material moves to the end of the collection conveyor belt 52, the waste material falls from the collection conveyor belt 52 into the collection box 54.

[0044] When the collection drive motor 53 drives the collection support shaft 51 to rotate, the collection support shaft 51 drives the first speed-changing gear 631 to rotate, and the first speed-changing gear drives the second speed-changing gear 632 to rotate. The diameter of the first speed-changing gear 631 is larger than that of the second speed-changing gear 632, and the rotation speed of the second speed-changing gear 632 is faster than that of the first speed-changing gear 631. This causes the second speed-changing gear 632 to drive the sweeping rod 61. The rotation speed of the sweeping rod 61 is faster than that of the collection support shaft 51, allowing the sweeping blade 62 on the sweeping rod 61 to move faster than the collection conveyor belt 52. This causes the sweeping blade 62 to agitate the waste on the collection conveyor belt 52, allowing the waste to fall from between the sweeping rod 61 and the collection conveyor belt 52 into the collection box 54.

[0045] When waste accumulates in the collection box 54 near the collection conveyor belt 52, and the height of the waste accumulation blocks the laser sensor 553, the controller 11 controls the mobile drive motor 552 to rotate back and forth. The mobile drive motor 552 drives one of the mobile support shafts 554 to rotate back and forth, causing the mobile conveyor belt 551 to move back and forth supported by the other mobile support shaft 554. The accumulated waste on the mobile conveyor belt 551 is moved back and forth by the mobile conveyor belt 551, and then the accumulated waste is spread on the mobile conveyor belt 551 under the action of the mobile conveyor belt 551.
