[0025] The following is combined with Figure 1-8 This application is described in further detail.
[0026] The embodiment of the present application discloses an HDI circuit board positioning and cutting device.
[0027] See also Figure 1 The positioning and cutting equipment includes a workbench 1, the top surface of the workbench 1 is a rectangular structure, and a mounting groove extending along the length direction is opened on the top of the workbench 1. A rotating roller located in the mounting groove is rotatably connected to the workbench 1. There are multiple rotating rollers and they are evenly spaced along the length direction of the mounting groove. A conveyor belt 11 connected end to end is sleeved on the outer peripheral side of the rotating roller. The workbench 1 is provided with a driving member, which is a driving motor 13. The driving motor 13 is fixed to the side wall of the workbench 1. The output shaft of the driving motor 13 is fixedly connected to one of the rotating rollers and is coaxially arranged. When the driving motor 13 is started, the rotating roller is driven to rotate, so that the conveyor belt 11 rotates in a cycle. One side of the conveyor belt 11 is a discharge part 12. During processing, the HDI circuit board is placed on the top of the conveyor belt 11, and the HDI circuit board is transported to the discharge part 12 through the conveyor belt 11.
[0028] See also Figure 1 and Figure 2, a mounting frame 3 is fixedly connected to the workbench 1, and the mounting frame 3 is located on the workbench 1 near the discharging part 12. The positioning and cutting device further includes a cutting knife 2. A mounting block 31 is slidably connected to the mounting frame 3, and the sliding direction of the mounting block 31 is perpendicular to the conveying direction of the conveyor belt 11. The cutting knife 2 is rotatably connected to the mounting block 31. A rotating member 32 is provided on the mounting block 31. The rotating member 32 is a rotating motor, and the rotating motor is fixedly connected to the mounting frame 3. The output shaft of the rotating motor is fixedly connected to the cutting knife 2 and is coaxially arranged. When the rotating motor is started, it drives the cutting knife 2 to rotate. A driving cylinder is also provided on the mounting frame 3. The driving cylinder is connected to an external origin. The piston rod of the driving cylinder is fixedly connected to the mounting block 31. When the driving cylinder is started, it drives the mounting block 31 to reciprocate, so that the cutting knife 2 can cut the HDI circuit board along the direction perpendicular to the conveying direction of the conveyor belt 11.
[0029] The positioning and cutting device further includes a clamping part, and the clamping part is arranged on the workbench 1. The clamping part includes an upper clamping plate 4 and a lower clamping plate 5. The lower clamping plate 5 slides up and down on the workbench 1. There are two groups of lower clamping plates 5 and they are symmetrically arranged. The conveyor belt 11 is located on both sides of the lower clamping plate 5. Each group of the lower clamping plates 5 has a plurality of them and they are evenly spaced along the conveying direction of the conveyor belt 11. In the initial state, there is a spacing between the top of the lower clamping plate 5 and the top of the conveyor belt 11. The upper clamping plate 4 slides up and down on the mounting frame 3, and the upper clamping plate 4 corresponds to the lower clamping plate 5 one by one. The upper clamping plate 4 and the lower clamping plate 5 are respectively in the structure of rectangular plates, and the length directions of the upper clamping plate 4 and the lower clamping plate 5 are respectively parallel to the conveying direction of the conveyor belt 11.
[0030] The workbench 1 is provided with a lower linkage plate 51, and there are two lower linkage plates 51 which are respectively fixedly connected to the lower clamping plates 5 on the same side. During use, the lower clamping plates 5 on the same side are linked through the lower linkage plate 51, so that the lower clamping plates 5 on the same side can move up and down synchronously. The workbench 1 is provided with a lower lifting member. The lower lifting member is a lower lifting cylinder 52. The lower lifting cylinder 52 is fixedly connected to the workbench 1. There are two lower lifting cylinders 52 and they correspond to the lower linkage plate 51 one by one. The piston rod of the lower lifting cylinder 52 is fixed at the middle position of the bottom of the lower linkage plate 51. The lower lifting cylinders 52 are connected to an external homologous air pipe. During use, the two lower lifting cylinders 52 can synchronously enter the forward stroke or the reverse stroke, and the lower linkage plate 51 is driven to move up and down through the lower lifting cylinder 52.
[0031] See Figure 2 And Figure 3, an upper linkage plate 41 is provided on the mounting bracket 3. There are two upper linkage plates 41, which are fixedly connected to the upper clamping plates 4 on the same side respectively. During use, the upper clamping plates 4 on the same side are linked by the upper linkage plate 41, so that the upper clamping plates 4 on the same side can move up and down synchronously. The workbench 1 is provided with an up-lifting member, and the up-lifting member is an up-lifting cylinder 42. The up-lifting cylinder 42 is fixedly connected to the mounting bracket 3. There are two up-lifting cylinders 42, which correspond to the upper linkage plates 41 one by one. The piston rod of the up-lifting cylinder 42 is fixed at the middle position of the top of the upper linkage plate 41. The up-lifting cylinders 42 are connected to an external homologous air pipe. During use, the two up-lifting cylinders 42 can synchronously enter the forward stroke or the reverse stroke, and drive the upper linkage plate 41 to move up and down through the up-lifting cylinder 42. When the up-lifting cylinder 42 and the down-lifting cylinder 52 are started at the same time, the upper clamping plate 4 and the lower clamping plate 5 approach each other. At this time, the lower clamping plate 5 first contacts the two side edges of the HDI circuit board, and then the lower clamping plate 5 drives the HDI circuit board to move up and approach the upper clamping plate 4. At this time, the upper clamping plate 4 and the lower clamping plate 5 cooperate with each other to clamp the HDI circuit board.
[0032] See Figure 1 And Figure 2 , an infrared emitter 15 is fixedly connected to the workbench 1 for emitting infrared rays at intervals upward. When the HDI circuit board is located on the conveyor belt 11 and passes through the infrared emitter 15, the HDI circuit board blocks the infrared rays; when the HDI circuit board moves upward away from the conveyor belt 11, the HDI circuit board does not block the infrared rays. The infrared emitter 15 is located on the side of the cutting knife 2 away from the discharging part 12 and is adjacent to it, and the infrared emitter 15 is located between two adjacent lower clamping plates 5 close to the discharging part 12. A controller 14 is fixedly connected to the workbench 1. The controller 14 is electrically connected to the control valves of the up-lifting cylinder 42 and the down-lifting cylinder 52 respectively, and the controller 14 is electrically connected to the infrared emitter 15 and the control valve of the driving cylinder. During use, the infrared emitter 15 emits infrared rays at intervals upward. When the infrared rays are blocked by the HDI circuit board and triggered, a signal is sent to the controller 14. The controller 14 controls the up-lifting cylinder 42 and the down-lifting cylinder 52 to enter the forward stroke at the same time, so that the upper clamping plate 4 and the lower clamping plate 5 can cooperate to clamp the HDI circuit board. Then the controller 14 controls the driving cylinder to start and controls the sliding of the mounting block 31, so that the cutting knife 2 cuts the HDI circuit board; after cutting is completed, the controller 14 controls the up-lifting cylinder 42 and the down-lifting cylinder 52 to enter the reverse stroke at the same time, so that the HDI circuit board falls back on the conveyor belt 11 and continues to be conveyed to the discharging part 12. At this time, the cut HDI circuit board is transmitted to the next process, and the uncut HDI circuit board continues to be cut by the cutting knife 2.
[0033] A first correction plate 43 is provided on the upper clamping plate 4 near the discharging part 12. The first correction plate 43 is hinged to one side of the upper clamping plate 4 near the discharging part 12. The upper clamping plate 4 is provided with a control assembly 6. When the upper clamping plate 4 moves downward close to the lower clamping plate 5, the control assembly 6 controls the first correction plate 43 to turn downward until it abuts against the side wall of the lower clamping plate 5 near the discharging part 12; when the upper clamping plate 4 moves away from the lower clamping plate 5, the control assembly 6 controls the first correction plate 43 to turn upward away from the lower clamping plate 5.
[0034] The control assembly 6 includes a control rope 61 and a control winding spring 62. The upper clamping plate 4 is rotatably connected with a rotating shaft 44, and the first correction plate 43 is fixedly connected to the rotating shaft 44. The control winding spring 62 is wound around the outer peripheral side of the rotating shaft 44. One end of the control winding spring 62 is clamped to the outer peripheral side of the rotating shaft 44, and the other end is clamped to the upper clamping plate 4. The control rope 61 is wound around the outer peripheral side of the rotating shaft 44. One end of the control rope 61 is connected to the outer peripheral side of the rotating shaft 44, and the other end is connected to the mounting bracket 3.
[0035] When the upper clamping plate 4 moves downward close to the lower clamping plate 5, the control rope 61 pulls the rotating shaft 44 to rotate, driving the first correction plate 43 to turn downward to adjust the position of the HDI circuit board, so that the position to be cut of the HDI circuit board can be aligned with the cutting tool 2. At this time, the control winding spring 62 enters an elastic winding state; when the upper clamping plate 4 moves upward away from the lower clamping plate 5, the control winding spring 62 elastically releases, driving the rotating shaft 44 to rotate in the reverse direction. At this time, the rotating shaft 44 winds the control rope 61, and the first correction plate 43 turns upward.
[0036] See Figure 4 And Figure 5 On the two lower clamping plates 5 near the discharging part 12, a set of second correction plates 53 are symmetrically arranged respectively (the second correction plates 53 are marked in Figure 2 ). Each set of second correction plates 53 has two and is symmetrically arranged. A sliding column 55 is slidably connected to the lower clamping plate 5 along the conveying direction of the conveyor belt 11. The sliding column 55 corresponds to the second correction plate 53 one by one and is fixedly connected, so that the second correction plate 53 is slidably connected to the lower clamping plate 5. The lower clamping plate 5 is provided with a power assembly 7. When the first correction plate 43 turns close to the lower clamping plate 5, the power assembly 7 drives the second correction plates 53 to approach each other, so that while the second correction plates 53 correct the HDI circuit board, the HDI circuit board is restricted from being displaced along the conveying direction of the conveyor belt 11 (the conveyor belt 11 is marked in Figure 1 ).
[0037] The power assembly 7 includes a power column 71 and a power plate 72. A power shaft 54 is rotatably connected inside the lower clamping plate 5. The power plate 72 is fixedly connected to the outer peripheral side of the power shaft 54. The power plate 72 is rotatably connected inside the lower clamping plate 5, and the power shaft 54 is located at the middle position of the power plate 72. The power column 71 is in a long strip columnar structure. The power column 71 is slidably connected to the lower clamping plate 5. The sliding direction of the power column 71 is parallel to the conveying direction of the conveyor belt 11 (the conveyor belt 11 is marked in Figure 1 ), and the power column 71 protrudes out of the lower clamping plate 5 towards the discharging part 12. The two ends of the power plate 72 away from the power shaft 54 respectively abut against the power column 71 and the corresponding sliding column 55. When the first correction plate 43 flips close to the lower clamping plate 5, the first correction plate 43 abuts against the power column 71. Then, during the process of the first correction plate 43 approaching the lower clamping plate 5, it pushes the power column 71 to slide into the lower clamping plate 5. At this time, the power column 71 drives the power plate 72 to rotate, so that the power plate 72 drives the sliding column 55 to move towards the direction close to the conveyor belt 11. At this time, the two opposite second correction plates 53 approach each other, and correct the HDI circuit board along the direction perpendicular to the conveying direction of the conveyor belt 11. And after correction, the two second correction plates 53 cooperate to clamp the HDI circuit board, reducing the possibility of the HDI circuit board being displaced during cutting.
[0038] A connecting spring 711 is fixedly connected to the side of the power column 71 away from the discharging part 12. The central axis of the connecting spring 711 is parallel to the length direction of the power column 71. The end of the connecting spring 711 away from the power column 71 is slidably connected to the power plate 72. When the two second correction plates 53 (the second correction plates 53 are marked in Figure 2 ) cooperate to clamp the HDI circuit board, the power column 71 continues to be pushed by the first correction plate 43 and slides into the lower clamping plate 5. At this time, the connecting spring 711 enters the compressed state, reducing the possibility that the power column 71 restricts the first correction plate 43 from approaching the lower clamping plate 5 when the two second correction plates 53 cooperate to clamp the HDI circuit board.
[0039] See Figure 5 and Figure 6 , a power coil spring 56 is wound and sleeved on the outer peripheral side of the power shaft 54. One end of the power coil spring 56 is clamped to the outer peripheral side of the power shaft 54, and the other end of the power coil spring 56 is clamped to the lower clamping plate 5. When the first correction plate 43 flips upwards and away from the lower clamping plate 5, the power coil spring 56 is released, driving the power shaft 54 to rotate in the reverse direction. At this time, the power plate 72 pushes the power column 71 to slide out of the lower clamping plate 5. At the same time, the power plate 72 pushes the sliding column 55 away from the conveyor belt 11 (the conveyor belt 11 is marked in Figure 1 ), so that the second correction plates 53 (the second correction plates 53 are marked in Figure 2 ) release the HDI circuit board.
[0040] See Figure 7 and Figure 8, a dialing roller 57 is rotatably connected to the lower clamping plate 5. The central axis of the dialing roller 57 is perpendicular to the conveying direction of the conveyor belt 11 (the conveyor belt 11 is marked in Figure 1 ). There are multiple dialing rollers 57, and they are evenly spaced along the conveying direction of the conveyor belt 11. When the lower clamping plate 5 drives the HDI circuit board to move upward and approach the upper clamping plate 4, the HDI circuit board abuts against the dialing roller 57. Both ends of the dialing roller 57 are fixedly connected with a dialing shaft 571 respectively, and the dialing shaft 571 is rotatably connected to the lower clamping plate 5. A linkage belt 572 (the linkage belt 572 is marked in Figure 5 ) is sleeved on the outer peripheral side of the dialing shaft 571. The linkage belt 572 is connected end to end. A connecting gear 573 is fixedly connected to the outer peripheral side of one of the dialing shafts 571. The connecting gear 573 is rotatably connected to the lower clamping plate 5. A connecting rack 712 is arranged on the outer peripheral side of the power column 71. The connecting rack 712 is slidably connected to the lower clamping plate 5. The connecting gear 573 meshes with the connecting rack 712.
[0041] When the power column 71 slides into the lower clamping plate 5, the connecting rack 712 drives the dialing shaft 571 to rotate through the connecting gear 573. At this time, through the linkage belt 572 (the linkage belt 572 is marked in Figure 5 ), the rest of the dialing shafts 571 are simultaneously brought into a rotating state, so that the dialing roller 57 enters a rotating state, driving the HDI circuit board to move in the direction of the discharging part 12 (the discharging part 12 is marked in Figure 4 ), making the HDI circuit board keep abutting against the first correction plate 43, and improving the cutting accuracy of the HDI circuit board. A friction layer 58 is fixedly connected to the outer peripheral side of the dialing roller 57. The friction layer 58 is made of rubber material, which is used to improve the friction force between the friction layer 58 and the HDI circuit board, and improve the effect of driving the HDI circuit board to abut against the first correction plate 43.
[0042] A dialing block 713 is fixedly connected to the top of the power column 71. The top end face of the dialing block 713 is in the same plane as the top end face of the lower clamping plate 5. When the first correction plate 43 is turned downward to abut against the lower clamping plate 5, the dialing block 713 slides to directly below the HDI circuit board, and the dialing block 713 abuts against the HDI circuit board. When the power column 71 slides out of the lower clamping plate 5, the dialing block 713 drives the HDI circuit board to move in the direction of the discharging part 12, accelerating the conveying speed of the HDI circuit board after cutting.
[0043] The implementation principle of an HDI circuit board positioning and cutting device in an embodiment of the present application is as follows: During operation, a whole sheet of HDI circuit boards to be cut is placed on the top of the conveyor belt 11, so that the cutting track of the HDI circuit boards is perpendicular to the conveying direction of the conveyor belt 11. When the HDI circuit boards move past the infrared emitter 15, the HDI circuit boards block the infrared rays, and at this time, the lower clamping plate 5 and the upper clamping plate 4 are close to each other, and when the lower clamping plate 5 abuts the HDI circuit boards, the cutting line between the adjacent HDI circuit boards near the discharge portion 12 moves to the side of the cutting knife 2 near the discharge portion 12; then, when the first correction plate 43 flips downward to abut the lower clamping plate 5, the first correction plate 43 corrects the HDI circuit boards along the conveying direction of the conveyor belt 11, so that the cutting line between the adjacent HDI circuit boards near the discharge portion 12 moves to the side directly below the cutting knife 2. At the same time, when the first correction plate 43 turns over and abuts the lower clamping plate 5, the power column 71 slides into the lower clamping plate 5, and the second correction plates 53 are close to each other, and the HDI circuit board is corrected along the conveying direction of the vertical conveyor belt 11, and the toggle roller 57 rotates to drive the HDI circuit board to maintain the state of abutting the first correction plate 43. When the upper clamping plate 4 and the lower clamping plate 5 cooperate to clamp and fix the HDI circuit board, the mounting block 31 drives the cutting knife 2 to slide and cut the HDI circuit board.
[0044] After the cutting is completed, the upper clamping plate 4 and the lower clamping plate 5 move away from each other, so that the HDI circuit board falls back to the top of the conveyor belt 11. At this time, the cut HDI circuit board continues to move toward the discharge portion 12 and separates from the lower clamping plate 5, and the remaining HDI circuit boards to be cut continue to be cut in the same way until the last two adjacent HDI circuit boards are cut and fall back on the conveyor belt 11. The HDI circuit boards move toward the discharge portion 12 respectively, and the HDI circuit board on the side away from the discharge portion 12 passes through the infrared emitter 15 during the interval between two infrared emission of the infrared emitter 15.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
