Description

Technical Field

[0001] This utility model relates to the field of circuit board dust removal technology, and in particular to a circuit board dust adhesion device. Background Technology

[0002] A circuit board, also known as a PCB, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Almost every electronic device, from small electronic watches and calculators to large computers, communication electronic equipment, and military weapon systems, uses circuit boards to enable electrical interconnection between integrated circuits and other electronic components. A circuit board consists of an insulating base plate, connecting wires, and pads for assembling and soldering electronic components, serving the dual function of a conductive circuit and an insulating base plate.

[0003] A search revealed that patent CN221429225U discloses a circuit board dust-adhesive device.

[0004] However, the above technical solution has the following problems: manually pushing the circuit board into the device for dust removal through the feeding hole and horizontal frame on the outer shell is inefficient and can easily cause the circuit board to be contaminated with more dust, increasing the burden on the internal dust removal structure, reducing the service life of the device, and increasing the number of times the internal dust collection bag needs to be cleaned. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing technologies where circuit boards are manually pushed into the device for dust removal through the feeding holes and horizontal frames on the outer shell. This method is inefficient, easily causes the circuit boards to accumulate more dust, increases the burden on the internal dust removal structure, reduces the service life of the device, and increases the frequency of cleaning the internal dust collection bag. Therefore, this utility model proposes a circuit board dust removal device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A circuit board dust removal device includes a feeding channel with two dust removal holes at the top and bottom for pre-treatment of the circuit board. The feeding channel is equipped with a moving mechanism for moving the circuit board and a fixing mechanism for stabilizing the circuit board. The dust removal holes of the feeding channel are equipped with a pre-treatment mechanism for dust removal of the circuit board.

[0008] In one possible design, the moving mechanism includes a first plate, a second plate, a motor, a lead screw, a slide bar, and two moving blocks. The first plate and the second plate are both fixedly mounted on the inner wall of the same feeding channel. Each of the first plate and the second plate has a sliding hole. The two ends of the lead screw are rotatably connected to the inner wall of the sliding hole of the same first plate via bearings. The two ends of the slide bar are fixedly connected to the inner wall of the sliding hole of the same second plate. The motor is fixedly mounted on one side of the first plate by bolts, and its output shaft rotatably passes through the first plate and is fixedly connected to one end of the lead screw. The two moving blocks are respectively threaded onto the lead screw and slidably mounted on the slide bar.

[0009] In one possible design, the fixing mechanism includes two air pumps, two U-shaped frames, two adsorption plates, and a placement plate. The two U-shaped frames are respectively fixedly installed on the side of the two moving blocks that are close to each other. The two air pumps are respectively located inside the two U-shaped frames and are respectively fixedly installed on the side of the two moving blocks that are close to each other by bolts. The two adsorption plates are respectively fixedly installed on the side of the two U-shaped frames that are close to each other and are both connected to the air inlet end of the air pumps through pipes. The air outlet end of the two air pumps is connected to the outside through pipes. The placement plate is used to place the circuit board and is fixedly installed between the two U-shaped frames.

[0010] In one possible design, the pretreatment mechanism includes four dust removal channels, four fans, four connecting plates, and multiple suction nozzles. The four dust removal channels are respectively fixedly installed on the inner walls of the four dust removal holes. The four fans are respectively fixedly installed on the inner walls of the four dust removal channels by bolts. The tops of the four connecting plates are respectively fixedly connected to one end of the four dust removal channels. The multiple suction nozzles are respectively installed on the four connecting plates and are all located inside the feeding channel.

[0011] In one possible design, the top of each of the four dust removal channels is fitted with a cover plate by a snap-fit ​​mechanism to shield and prevent dust from entering the dust removal channel.

[0012] In one possible design, the placement plate has three rectangular holes to facilitate the removal of dust from the bottom of the circuit board.

[0013] In one possible design, an installation plate is fixedly fitted on the outer side of one end of the feeding channel to facilitate the installation of the feeding channel, and the four corners of the installation plate are provided with installation holes for easy installation.

[0014] In this application, during use, the circuit board is placed on the placement plate, which supports the circuit board. The controller starts the air pump, which generates negative pressure at the adsorption plate. Due to the multiple tiny adsorption holes on the adsorption plate, the circuit board is stably adsorbed onto the placement plate. The controller starts the motor, and the motor's output shaft drives the lead screw to rotate. Since one of the moving blocks is threaded onto the lead screw, it moves along the axial direction of the lead screw under the action of the threaded engagement. The other moving block is slidably fitted onto the slide rod, playing an auxiliary support and guiding role, so that the two moving blocks can move synchronously and stably. The two moving blocks drive the U-shaped frame, air pump, adsorption plate, and circuit board on the placement plate, which are fixed on them, to move together and enter the feeding channel. During the movement of the circuit board, the fan is started, and the fan generates airflow in the dust removal channel. The suction nozzle sucks the dust on the surface of the circuit board into the connecting plate, and then discharges it through the dust removal channel, realizing the dust removal pretreatment of the circuit board surface and reducing the burden on the dust adhesion device.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this invention, the pretreatment mechanism is equipped with dust removal holes and corresponding dust removal channels, fans, connecting plates and suction nozzles at the top and bottom of the feeding channel. This allows for simultaneous dust removal of the upper and lower surfaces of the circuit board, effectively removing floating dust from the circuit board surface, improving the comprehensiveness and thoroughness of dust removal, providing a good foundation for the subsequent dust adhesion process, reducing the burden on the dust adhesion device, and improving the dust adhesion effect. At the same time, the circuit board is moved and fed by the moving mechanism, reducing the chance of manual pushing and getting dusty. Attached Figure Description

[0022] 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.

[0023] Example 1

[0024] Reference Figures 1-4 A dust-adhesive device includes a feeding channel 2, a moving mechanism, a fixing mechanism, a pretreatment mechanism, and a mounting plate 1. The feeding channel 2 is the main frame of the device, and the mounting plate 1 is fixedly sleeved on the outer side of one end. Mounting holes are provided at the four corners of the mounting plate 1. Through these mounting holes, the entire device can be conveniently installed on the designated position on the outer shell of the dust-adhesive device to ensure the stability of the device.

[0025] Plate 5 and Plate 6 are both securely mounted on the inner wall of the feed channel 2 by welding or other fixing methods, providing a mounting base for subsequent components. Both plates 5 and 6 have sliding holes for the installation of the lead screw 7 and slide rod 8. The two ends of the lead screw 7 are rotatably connected to the inner walls of the sliding holes on both sides of Plate 5 via bearings, ensuring smooth rotation of the lead screw 7. The two ends of the slide rod 8 are fixedly connected to the inner walls of the sliding holes on both sides of Plate 6, providing guidance for the movement of the moving block 9. The motor 4 is fixedly mounted on one side of Plate 5 by bolts, and its output shaft rotates through Plate 5. Fixedly connected to one end of the lead screw 7, when the motor 4 starts, it can drive the lead screw 7 to rotate. There are two moving blocks 9. One moving block 9 is threaded on the lead screw 7 and slidably connected to the sliding hole of the first plate 5. The other moving block 9 is slidably fitted on the slide rod 8 and slidably connected to the inner wall of the sliding hole of the second plate 6. When the lead screw 7 rotates, due to the threaded engagement, the moving block 9 threaded on the lead screw 7 will move along the axial direction of the lead screw 7, while the moving block 9 slidably fitted on the slide rod 8 plays an auxiliary support and guiding role, so that the two moving blocks 9 can move synchronously and stably.

[0026] Two U-shaped frames 11 are fixedly mounted on the side of the two moving blocks 9 near each other by welding or other fixing methods. They move with the movement of the moving blocks 9. Two air pumps 10 are located inside the two U-shaped frames 11 and are fixedly mounted on the side of the two moving blocks 9 near each other by bolts. The air pumps 10 serve as the source of adsorption force, providing power for adsorbing the circuit board. Two adsorption plates 12 are fixedly mounted on the side of the two U-shaped frames 11 near each other and are provided with multiple tiny adsorption holes. They are all connected to the air inlet of the air pumps 10 through pipes. When the air pumps 10 are started, a negative pressure is generated at the adsorption plate 12, thereby adsorbing the circuit board. The air outlet of the two air pumps 10 is connected to the outside through pipes to discharge the gas generated during the adsorption process. The placement plate 13 is used to place the circuit board. It is fixedly mounted between the two U-shaped frames 11 by welding or other fixing methods. The placement plate 13 has three rectangular holes 14. These rectangular holes 14 facilitate the treatment of floating dust on the bottom of the circuit board.

[0027] This application can be used in the field of circuit board dust removal, or in other fields applicable to this application.

[0028] Example 2

[0029] refer to Figures 1-4 Based on Embodiment 1, an improved circuit board dust-adhesion device includes:

[0030] Two dust removal holes are opened at the top and bottom of the feeding channel 2. Four dust removal channels 3 are fixedly installed on the inner walls of the four dust removal holes by welding or other fixing methods. The top of each of the four dust removal channels 3 is fitted with a cover plate 15 by a snap fastener. The cover plate 15 is used to cover and isolate the dust removal channels 3 to prevent dust from entering the dust removal channels 3 when the device is not working. Four fans 16 are fixedly installed on the inner walls of the four dust removal channels 3 by bolts. When the fans 16 are started, they will generate airflow in the dust removal channels 3 to suck away the floating dust on the surface of the circuit board and reduce the burden on the dust sticking device. The tops of the four connecting plates 17 are fixedly connected to one end of the four dust removal channels 3. Multiple suction nozzles 18 are respectively installed on the four connecting plates 17 and are all located inside the feeding channel 2. The suction nozzles 18 can more effectively suck the dust on the surface of the circuit board into the dust removal channels 3.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of motor 4, air pump 10 and fan 16 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. Motor 4, air pump 10 and fan 16 are all connected to the controller fixedly installed on the feed channel 2 through the line and are powered by an external power source.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
