Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a circuit board dust removal device. Background Technology
[0002] The production process of printed circuit boards (PCBs) involves cutting and processing PCB materials. Therefore, a dust removal device needs to be designed in the PCB production process to remove dust from the surface of the PCBs. Otherwise, the PCBs may easily become unqualified in subsequent production stages due to substandard performance.
[0003] Utility model disclosure CN212519590U discloses a circuit board dust removal device, including a base and a roller shutter dustproof door. A frame is installed near the two ends of the top of the base, and a sliding groove is fitted onto the inner wall of the frame. A sliding frame moves within the sliding groove, and the roller shutter dustproof door is fixedly connected above the sliding frame. A limiting groove is provided at the center of the top of the base. When a user performs dust removal processing on a circuit board, this dust removal device for circuit board production can fully utilize the self-circulating translational transmission formed between the roller and a third motor for dust removal. The conveyor belt and dust removal brushes work together. The user only needs to place the workpiece at the left end of the conveyor belt, and the self-transmission formed by the roller and the third motor will transport the workpiece to the inside of the frame for dust removal. This increases the integration of the device during the dust removal process and also improves the ease of operation for the user.
[0004] The dust removal device described above can only clean one side of the circuit board and cannot clean the circuit board from all sides. The cleaned side of the circuit board is prone to dust accumulation in subsequent work, which affects the performance of the product. Summary of the Invention
[0005] The purpose of this invention is to provide a circuit board dust removal device to solve the problem mentioned in the background art of not being able to clean circuit boards in all directions.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a circuit board dust removal device, comprising a first protective plate and a second protective plate, wherein a common connecting plate and a transmission mechanism are installed between the first and second protective plates, a device plate is installed on the first protective plate, a first cylinder and a second cylinder are rotatably mounted on the first and second protective plates respectively, a lifting mechanism is installed on the output shaft of both the first and second cylinders, a clamping plate is connected to the lifting mechanism, the two clamping plates are located between the first and second protective plates, a transmission gear is installed at the end of the first cylinder away from its output shaft, a rack meshes on the transmission gear, a third cylinder is connected to one end of the rack, the third cylinder is mounted on the device plate, a common bracket is connected to the first and second protective plates, a fourth cylinder is installed on the bracket, and an ion fan is installed on the output shaft of the fourth cylinder.
[0007] Preferably, both the first and second protective plates are provided with rotating holes, and the two rotating holes are on the same horizontal line as the first and second cylinders.
[0008] Preferably, an L-shaped plate is installed on the side of the second protective plate away from the first protective plate, and the second cylinder is rotatably mounted on the L-shaped plate.
[0009] Preferably, rubber pads are slidably mounted on both clamps.
[0010] Preferably, a first sliding groove is provided on the side of the two clamping plates that are close to each other, and a first slider is installed on each of the two rubber pads, the first slider being adapted to the first sliding groove.
[0011] Preferably, the device plate has a second sliding groove, and a second slider is installed on the rack, the second slider being adapted to the second sliding groove.
[0012] Preferably, the vertical distance from the transmission mechanism to the center of the clamping plate is greater than half the length of the clamping plate.
[0013] The beneficial effects of this utility model are:
[0014] In this invention, a first and a second cylinder bring two clamping plates closer to the circuit board. A lifting mechanism moves the clamping plates downwards until they are at the same height as the circuit board, thus clamping the circuit board tightly. Then, an ion fan is moved to a suitable position and turned on to remove dust from the upward-facing side of the circuit board. After cleaning, a third cylinder is activated, moving a rack and pinion, which in turn drives a transmission gear. This causes the first cylinder, connected to the transmission gear, to rotate synchronously, causing the circuit board held by the two clamping plates to flip. Before the circuit board flips, the lifting mechanism moves the clamping plates and the circuit board upwards, preventing the circuit board from contacting the transmission mechanism during flipping. This restricts the flipping of the circuit board, allowing for comprehensive cleaning of the circuit board. This device can meet the multi-directional cleaning needs of circuit boards, offering high cleaning efficiency and excellent cleaning results. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4A circuit board dust removal device includes a first protective plate 1 and a second protective plate 2. A connecting plate 3 and a transmission mechanism 4 are installed between the first protective plate 1 and the second protective plate 2. A device plate 11 is installed on the first protective plate 1. A first cylinder 5 and a second cylinder 6 are rotatably installed on the first protective plate 1 and the second protective plate 2, respectively. A lifting mechanism 22 is installed on the output shaft of the first cylinder 5 and the second cylinder 6. A clamping plate 7 is connected to the lifting mechanism 22. The two clamping plates 7 are located between the first protective plate 1 and the second protective plate 2. A transmission gear 8 is installed at the end of the first cylinder 5 away from its output shaft. A rack 9 meshes with the transmission gear 8. A third cylinder 10 is connected to one end of the rack 9. The third cylinder 10 is installed on the device plate 11. A bracket 12 is connected to the first protective plate 1 and the second protective plate 2. A fourth cylinder 13 is installed on the bracket 12. An ion fan 14 is installed on the output shaft of the fourth cylinder 13.
[0022] When using this device, the operator first places the circuit board on the transmission mechanism 4, which then transports it to the area below the ion fan 14. Next, the first cylinder 5, the second cylinder 6, and the lifting mechanism 22 are activated. The first cylinder 5 and the second cylinder 6 bring the two clamping plates 7 closer to the circuit board. The lifting mechanism 22 then moves the clamping plates 7 downwards until they are at the same height as the circuit board, thus clamping the circuit board securely. Afterwards, the ion fan 14 is moved to the appropriate position and then turned on to remove dust from the side of the circuit board facing upwards. After cleaning, the third cylinder 10 is activated, which drives the rack 9 to move, thereby pushing the transmission gear 8 to rotate. This causes the first cylinder 5, which is connected to the transmission gear 8, to rotate synchronously, thereby causing the circuit board held by the two clamping plates 7 to flip. Before the circuit board flips, the lifting mechanism 22 moves the clamping plates 7 and the circuit board upward, so that the circuit board will not come into contact with the transmission mechanism 4 when it flips. Thus, the flipping of the circuit board is restricted by the transmission mechanism 4, thereby cleaning the circuit board from all directions. This device can meet the multi-directional cleaning needs of the circuit board, with high cleaning efficiency and good cleaning effect.
[0023] Specifically, in this embodiment, both the first protective plate 1 and the second protective plate 2 are provided with rotating holes 15. The two rotating holes 15 are on the same horizontal line as the first cylinder 5 and the second cylinder 6, so that the first cylinder 5 and the second cylinder 6 can be connected to the corresponding clamping plate 7 through the corresponding rotating holes 15, so that the first cylinder 5 and the second cylinder 6 can drive the corresponding clamping plate 7 to move synchronously when they are started.
[0024] Specifically, in this embodiment, an L-shaped plate 16 is installed on the side of the second protective plate 2 away from the first protective plate 1, and the second cylinder 6 is rotatably mounted on the L-shaped plate 16, so that the L-shaped plate 16 can provide support for the second cylinder 6, thereby avoiding the situation where the second cylinder 6 shakes due to insufficient support when rotating.
[0025] Specifically, in this embodiment, rubber pads 17 are slidably installed on both clamping plates 7, so that when the clamping plate 7 clamps the circuit board, the rubber pads 17 slidably installed on it first come into contact with the circuit board, thereby increasing the friction between the clamping plate 7 and the circuit board, and at the same time avoiding damage to the circuit board caused by the clamping plate 7 directly contacting the circuit board.
[0026] Specifically, in this embodiment, a first sliding groove 18 is provided on the side of the two clamping plates 7 that are close to each other, and a first slider 19 is installed on each of the two rubber pads 17. The first slider 19 is adapted to the first sliding groove 18, so that the two rubber pads 17 can be slidably installed on the corresponding clamping plates 7 through the compatibility of the first slider 19 and the first sliding groove 18. When the rubber pads 17 are worn and need to be replaced, they can be replaced quickly.
[0027] Specifically, in this embodiment, a second sliding groove 20 is provided on the device plate 11, and a second slider 21 is installed on the rack 9. The second slider 21 is adapted to the second sliding groove 20, so that the rack 9 can be slidably connected to the device plate 11 through the second slider 21 and the second sliding groove 20. When the rack 9 moves, the cooperation between the second sliding groove 20 and the second slider 21 can limit the movement direction of the rack 9, thereby preventing the rack 9 from deviating when it moves.
[0028] Specifically, in this embodiment, the vertical distance from the transmission mechanism 4 to the center of the clamping plate 7 is greater than half the length of the clamping plate 7, so that when the clamping plate 7 rotates, its two ends cannot contact the transmission mechanism 4, thereby avoiding the situation where the transmission mechanism 4 restricts the clamping plate 7 and causes the clamping plate 7 to fail to rotate.
[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
