Description

Technical Field

[0001] The utility model relates to the technical field of edge grinding machines, in particular to a circuit board edge grinding machine. Background Art

[0002] PCB board, also known as printed circuit board, is an important electronic component. It is the support body of electronic components and the carrier for the electrical connection of electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board.

[0003] Some existing PCB board edge grinding machines use rotating rollers to transfer PCB boards when in use. In these PCB boards, one side will first be placed against a support plate. After the PCB board on this side is polished, the position of the PCB board needs to be changed before continuing to polish. However, these devices can only polish one side at a time. The position of the PCB board needs to be changed multiple times to complete the polishing of the PCB board edge. This will take a long time to polish a PCB, thereby affecting work efficiency. To this end, we provide a circuit board edge grinding machine to solve the above problems. Utility Model Content

[0008] Furthermore, the adjustment mechanism includes a second motor, which is mounted on the outer surface of the workbench, and an output end of the second motor is fixedly connected to a threaded rod.

[0009] Furthermore, the outer surface of the threaded rod is rotatably connected to the interior of the workbench, and the outer surface of the threaded rod is threadedly connected to a transmission plate.

[0010] Furthermore, the outer surface of the transmission plate is slidably connected to the interior of the workbench, and the upper surface of the transmission plate is fixedly connected to the bottom surface of the support plate.

[0014] 3) Beneficial effects

[0015] Compared with the existing technology, this edge grinding machine has the following beneficial effects:

[0016] 1. The utility model cooperates with the push plate and the adjustment mechanism. First, the push plate can push the PCB to move. After the PCB is placed on the conveyor belt, the conveyor belt will move the push plate. The PCB is pushed by the moving push plate, avoiding the situation where the conveyor belt alone cannot push the PCB. The adjustment mechanism can change the distance between the two support plates. Before grinding the PCB, the adjustment mechanism can be started first. The adjustment mechanism will move the two support plates closer or farther away from each other, so that the PCB can be placed exactly between the support plates, so that the grinding wheels on both sides can grind the edge of the PCB. It is very easy to use and solves the problem of only being able to grind one side at a time, which affects efficiency.

[0017] 2. The utility model cooperates with the slide rail, the limit rod and other components. When the adjustment mechanism controls the movement of the support plate, the slide rail can control the direction of movement of the support plate, thereby avoiding deviation in the position of the support plate. When adjusting the position of the grinding wheel, the limit rod can be rotated. The rotation of the limit rod can withdraw a part of the lower slider, thereby reducing the force of the limit block and the lower slider pressing against the protective shell, so that the lower slider can move. At this time, the limit rod can be pushed to move the lower slider, and the grinding wheel will move with the movement of the lower slider, so that the position of the grinding wheel can be adjusted, which is very convenient.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a circuit board edge grinding machine, including a workbench 1, the upper surface of the workbench 1 is fixedly connected to a slide rail 2, the upper surface of the slide rail 2 is slidably connected to a support plate 3, the workbench 1 will fix the position of the slide rail 2, when the support plate 3 moves, the slide rail 2 can control the direction of movement of the support plate 3, thereby avoiding deviation in the position of the support plate 3.

[0025] A conveyor belt 4 is installed inside the support plate 3, and a push plate 5 is installed on the outer surface of the conveyor belt 4. An adjustment mechanism 6 is provided inside the workbench 1. There are two support plates 3, and each support plate 3 is installed with a conveyor belt 4. The two conveyor belts 4 move at the same frequency. The conveyor belt 4 will fix the position of the push plate 5. When the PCB board is placed on the conveyor belt 4, the conveyor belt 4 can push the PCB board to move by moving the push plate 5.

[0026] The outer surface of the support plate 3 is fixedly connected to a protective shell 7, and the upper surface of the protective shell 7 is fixedly connected to a limit plate 8. The support plate 3 will fix the position of the protective shell 7, and the protective shell 7 can prevent people from being injured by objects inside the protective shell 7. The protective shell 7 will fix the position of the limit plate 8.

[0027] The upper surface of the protective shell 7 is slidably connected to a motor 9, and the output end of the motor 9 is fixedly connected to a grinding wheel 10. The motor 9 can slide along the upper surface of the protective shell 7. When the motor 9 is started, the grinding wheel 10 can be rotated. When the position of the motor 9 changes, the position of the grinding wheel 10 will also move.

[0028] The adjustment mechanism 6 includes a second motor 601, which is installed on the outer surface of the workbench 1. The output end of the second motor 601 is fixedly connected to a threaded rod 602. The workbench 1 fixes the position of the second motor 601. The workbench 1 can prevent the second motor 601 from rotating at startup, and can make the threaded rod 602 rotate when the second motor 601 starts.

[0029] The outer surface of the threaded rod 602 is rotatably connected to the inner part of the workbench 1. The outer surface of the threaded rod 602 is threadedly connected to a transmission plate 603. The workbench 1 can reduce the vibration generated by the threaded rod 602 during rotation and control the movement of the transmission plate 603 through the rotation of the threaded rod 602.

[0030] The outer surface of the transmission plate 603 is slidably connected to the inside of the workbench 1, and the upper surface of the transmission plate 603 is fixedly connected to the bottom surface of the support plate 3. The workbench 1 can prevent the transmission plate 603 from rotating along with the threaded rod 602. The transmission plate 603 will fix the position of the support plate 3, and will move with the support plate 3 when the transmission plate 603 moves. There are two transmission plates 603. When the threaded rod 602 rotates, the two transmission plates 603 will move in opposite directions, thereby controlling the distance between the two support plates 3.

[0031] The outer surface of the limit plate 8 is slidably connected to the outer surface of the motor 9, and the upper slider 11 is slidably connected to the inside of the protective shell 7, and the lower slider 12 is slidably connected to the inside of the protective shell 7. The limit plate 8 will limit the position of the motor 9 to prevent the motor 9 from rotating at startup. The protective shell 7 can limit the position to which the upper slider 11 can move, avoiding deviation in the position of the upper slider 11. The protective shell 7 will also limit the position to which the lower slider 12 can move, avoiding deviation in the position of the lower slider 12.

[0032] The output end of motor 19 is connected to the internal rotation of the upper slider 11, and the outer surface of the grinding wheel 10 is connected to the internal rotation of the lower slider 12. The output end of motor 19 cannot be pulled out from the upper slider 11. The upper slider 11 is used to limit the position of motor 19 so that motor 19 cannot fall from the protective shell 7. The output end of motor 19 and the lower slider 12 are used to limit the position of the grinding wheel 10 to avoid large vibration when the grinding wheel 10 rotates.

[0033] The internal sliding connection of the protective shell 7 is connected to the limit block 13, and the internal rotation connection of the limit block 13 is connected to the limit rod 14. The outer surface of the limit rod 14 is connected to the internal thread of the lower slider 12. The protective shell 7 will limit the position to which the limit block 13 can move, and the limit rod 14 cannot be pulled out from the limit block 13. After the limit rod 14 is tightened, the gap between the limit block 13 and the lower slider 12 will be reduced. After contacting the protective shell 7, there will be a large friction force, which makes the lower slider 12 unable to move easily, thereby fixing the position of the grinding wheel 10.

[0034] Working principle: When using the device, first start motor 2 601. Motor 2 601 starts to rotate the threaded rod 602. The rotation of the threaded rod 602 will move the transmission plate 603. The movement of the transmission plate 603 will drive the support plate 3 to move. According to the size of the PCB board, the support plate 3 is moved to a suitable position. Then, the limit rod 14 is rotated. When the lower slider 12 can move, the limit rod 14 and the motor 1 9 are pushed to move the grinding wheel 10 to a suitable position. Then, the limit rod 14 is tightened, and the motor 1 9 is started to rotate the grinding wheel 10. Then, the PCB board is placed on it and the conveyor belt 4 is started. The conveyor belt 4 will move the push plate 5. The movement of the push plate 5 will push the PCB board to move, so that the PCB board passes through the grinding wheel 10 to complete the edge grinding of the PCB board.
