[0003] The existing circuit board cleaning equipment is mostly preliminary cleaned by using a brush to remove the dust adhered, but the brush will rub the circuit board, which may generate static electricity, causing damage to the surface components of the circuit board in varying degrees and increasing the scrap rate of the circuit board. SUMMARY

[0004] The utility model discloses a surface dust removal device for circuit board processing, which adopts a symmetrical dust removal method of air suction, reduces the scrap caused by static electricity of the circuit board during dust removal, and improves the qualified rate of circuit board production.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0008] Preferably, the driving structure includes a knob; the knob is fixed to the end of the bidirectional lead screw, and the knob is located outside the frame; a side plate is fixed outside the frame, and the side plate is threadedly connected with a bolt pointing to the knob; when the bolt abuts against the knob, the knob remains fixed.

[0009] Preferably, the side surface of the knob is provided with a plurality of positioning holes for inserting the bolt.

[0010] Preferably, the top material mechanism includes an electric push rod, which is fixed to the surface of the base plate and has a top plate that enters and exits the frame; the area of ​​the top plate is smaller than the area occupied by the hollow part of the frame.

[0011] Preferably, the first lead screw assembly includes a bearing bracket, a guide rail, and a screw, with the guide rail fixed to the base plate; the guide rail and the screw are arranged in parallel; a sliding rod slides on the guide rail, and the screw and the sliding rod are threadedly connected; the bearing bracket is fixed to the surface of the base plate, and the two ends of the screw are connected to the bearing bracket; the base plate is equipped with a motor for driving the screw.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0015] 1. The clamping assembly can hold the circuit board and then move it between the two dust caps to directly suction the dust from both sides of the circuit board. This reduces the damage to the circuit board caused by friction and static electricity. Secondly, compared with blowing, suction reduces the airflow impact damage to the circuit board components. Furthermore, simultaneous dust removal from both sides is more efficient.

[0016] 2. The top feeding mechanism transports the circuit board to the frame position, which facilitates quick clamping of the circuit board and quick removal of the circuit board after dust removal.

[0017] 3. The knob design allows the frame to clamp circuits of varying widths, increasing the adaptability of the dust removal device to different circuit board sizes. The positioning holes enable quick and precise clamping and positioning, resulting in more stable clamping. Because the positioning hole positions differ depending on the knob angle, factories can create corresponding positioning holes based on the size and model of the circuit boards being produced. Therefore, once the circuit board is properly clamped, the positioning hole and bolt are aligned, allowing for precise and quick bolt insertion and locking at the designated position.

[0018] 4. This design can remove dust from both sides of the circuit board by suction. Compared with blowing dust removal, it solves the problem that existing blowing dust removal methods easily blow up the collected dust, thereby reducing the dust removal effect. Attached Figure Description

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Embodiment 1, see Figure 1 A surface dust removal device for circuit board processing, comprising a bottom plate 1 which can be used for dust removal device for circuit board processing;

[0035] The bottom plate 1 is a metal plate, and the bottom plate 1 can be fixed on the ground of the workshop by ground nails and screws.

[0036] The surface of the bottom plate 1 is provided with a dust removal device 7, the dust removal device 7 comprises a dust suction machine 701, the dust suction machine 701 is connected with a dust suction pipe 702, and the two dust suction pipes 702 are each connected with a dust suction cap 703 in communication;

[0037] The model of the dust suction machine 701 can be KJT-30JH.

[0038] The two dust suction caps 703 are arranged symmetrically upward and downward, and the two dust suction caps 703 have a gap therebetween, which is used for placing a circuit board, and the two dust suction caps 703 upward and downward are used for air suction type dust removal of two sides of the circuit board.

[0039] The dust suction cap 703 has a circular truncated cone structure, and the inner surface of the dust suction cap 703 is smooth, so that dust is gathered and sucked into the dust suction machine 701, and the circular truncated cone structure and the smooth inner wall of the dust suction cap 703 can greatly improve the defect that dust is hidden in the rough inner wall of the upper dust suction cap 703 and falls down when air suction is stopped, so that the dust removal effect is weakened.

[0040] The following is a description of the circuit board conveying structure.

[0041] The bottom plate 1 is provided with a sliding rod 2, the sliding rod 2 is an L-shaped rod body, the upper end of the sliding rod 2 is a bent short rod, the short rod is used for placing a circuit board, and the L-shaped sliding rod 2 provides a space for the sliding rod 2 to enter and exit between the two dust suction caps 703.

[0042] The bottom plate 1 is provided with a first lead screw assembly 6 for driving the sliding rod 2 to move back and forth to realize that the frame 301 enters and exits between the two dust suction caps 703.

[0043] The first lead screw assembly 6 comprises a bearing frame 601, a guide rail 603 and a screw rod 602, and the guide rail 603 is fixed to the bottom plate 1.

[0044] The bearing frame 601 is fixed to the surface of the bottom plate 1, and the two ends of the screw rod 602 are connected with the bearing frame 601.

[0045] The guide rail 603 and the screw rod 602 are arranged in parallel.

[0046] The sliding rod 2 slides on the guide rail 603, and the screw rod 602 is threadedly connected with the sliding rod 2.

[0047] The bottom plate 1 is provided with a motor 81 for driving the screw rod 602 to rotate forward and backward, and the motor 81 is fixed to the bottom plate 1 through a frame body.

[0048] Obviously, by controlling the forward and reverse rotation of the motor 81, the sliding rod 2 can be controlled to move in and out between the two dust suction caps 703 along the guide rail 603.

[0049] The following is a description of the circuit board clamping structure.

[0050] Reference Figure 1 and Figure 2 ;

[0051] The sliding rod 2 is equipped with a clamping assembly 3 for clamping the circuit board. The clamping assembly 3 includes a clamping frame 301, which is hollow and has a drive structure 4 for controlling the opening and closing of the clamping action.

[0052] The inner wall of the frame 301 has two symmetrical sliding grooves 302, and a clamping plate 304 slides in the sliding groove 302. The clamping plate 304 is a long strip plate; the clamping plate 304 slides back and forth on the sliding groove 302.

[0053] The frame 301 is provided with a bidirectional lead screw 303 that controls the opening and closing of two clamping plates 304. The threads on both sides of the bidirectional lead screw 303 have opposite directions and the same pitch. The two clamping plates 304 are threadedly connected to both sides of the bidirectional lead screw 303.

[0054] The bidirectional lead screw 303 is rotatably connected to one side edge of the frame 301, and the frame 301 is provided with a bearing on one side edge, so the bidirectional lead screw 303 can rotate freely in both directions on the frame 301.

[0055] Therefore, driven by the bidirectional lead screw 303, the two clamping plates 304 can clamp together in opposite directions or separate in opposite directions.

[0056] The bidirectional lead screw 303 requires a knob 401 to drive it. The knob 401 is fixed to the end of the bidirectional lead screw 303 and is located on the outside of the frame 301. A side plate 403 is fixed to the outside of the frame 301. The side plate 403 is threadedly connected to a bolt 402 pointing to the knob 401. When the bolt 402 abuts against the knob 401, the knob 401 remains fixed.

[0057] Employees can manually rotate knob 401.

[0058] The knob 401 has several positioning holes 404 on its side for bolts 402 to be inserted. In this embodiment, there are twenty positioning holes 404.

[0059] Since frame 301 is hollow, placing the circuit board on it is very inconvenient. Therefore, a top-loading mechanism 5 was designed, as detailed in [reference needed]. Figures 3-5 ;

[0060] The base plate 1 is equipped with a top material mechanism 5 that vertically transports the circuit board to the frame 301 station.

[0061] The top material mechanism 5 includes an electric push rod 501 fixed to the surface of the bottom plate 1, and the electric push rod 501 is provided with a top plate 502 entering and exiting the frame 301; the area of the top plate 502 is smaller than the area of the hollow part of the frame 301, and the edges of the top plate 502 and the frame 301 have a gap in the top view.

[0062] Working principle or structural principle:

[0063] Firstly, the top plate 502 is raised above the frame 301, and the worker needs to place the circuit board on the surface of the top plate 502, and then the top plate 502 is lowered into the frame 301;

[0064] Secondly, the knob 401 drives the bidirectional screw rod 303 to rotate, and when the bidirectional screw rod 303 rotates, the bidirectional screw rod 303 drives the clamping plates 304 to approach each other, thereby clamping and fixing the circuit board, and after fixing, the rotating bolt 402 is rotated to make the bolt 402 and the corresponding positioning hole 404 inserted and connected;

[0065] Thirdly, the top plate 502 is lowered and separated from the circuit board.

[0066] Fourthly, the motor 81 is started, and when the screw rod 602 rotates, the frame 301 and the circuit board fixed on the surface thereof are displaced, and the sliding rod 2 moves the circuit board between the two dust collection caps 703.

[0067] Fifthly, the dust collector 701 is started, and the dust collector 701 sucks the dust on the surface of the circuit board into the interior, thereby achieving dust removal, and after completing the dust removal, the circuit board is brought back to the original position;

[0068] Sixthly, the electric push rod 501 is started, the top plate 502 is raised, the circuit board is separated from the frame 301 after the knob 401 is rotated, the circuit board is supported by the top plate 502, the top plate 502 is further raised above the frame 301, and the worker can take down the circuit board.

[0069] The rising height of the electric push rod 501 can be controlled by the rotation number of the servo motor through the self-programming, or a magnetic limit switch or a contact limit switch and the electric push rod 501 can be triggered by the limit switch, which is a relatively conventional prior art and will not be described in detail.

[0070] In summary, the device has the advantages of convenient material taking and good dust removal effect. In order to reduce the collision strength of the circuit board when placed on the top plate 502, a soft cushion layer can be placed on the upper surface of the circuit board.

[0071] Embodiment 2, a surface dust removal device for circuit board processing, which is different from embodiment 1, and the difference is referred to Figure 6The clamping surface of the clamping plate 304 is a concave surface, the concave surfaces of the two clamping plates 304 are oppositely arranged, and the concave surface is formed by the inclined surfaces from the upper and lower ends of the clamping plate 304 to the center; such arrangement is to make the circuit board more stably clamped on the clamping plate 304;

[0072] The concave surface formed by the inclined surfaces is beneficial to the circuit board slowly sliding into the center concave part from bottom to top, and is also beneficial to the circuit board slowly falling from top to bottom.
