Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a cleaning structure for the copper-plated surface of a circuit board. Background Art

[0002] Copper plating of circuit boards is a common process that forms a copper layer on the surface of the circuit board through electrolytic copper plating to improve its conductivity and corrosion resistance.

[0003] In order to achieve better copper plating effect, grooves or protrusions are usually designed on the surface of the circuit board to distinguish the copper plating areas and form steps. However, due to process reasons, some impurities may adhere to the surface of the circuit board after the copper plating is completed. Therefore, these impurities need to be removed after the copper plating is completed.

[0004] At present, the commonly used cleaning method is to use a fiber brush to clean the surface of the circuit board linearly or rotary. However, when cleaning to the step position, due to the existence of the step, the fiber brush may not be able to completely remove the impurities on the step, and the staff needs to check and clean it.

[0005] Based on this, those skilled in the art have proposed a novel cleaning structure for the copper-plated surface of a circuit board. Utility Model Content

[0006] In view of the above problems existing in the prior art, the main purpose of the utility model is to solve the problem that when cleaning a circuit board, due to the presence of steps, the fiber brush may not be able to completely remove impurities on the steps, and staff are required to check and clean them.

[0007] The technical solution of the utility model is as follows: it includes a mounting mechanism and also includes:

[0008] A driving mechanism, the driving mechanism is arranged inside the mounting mechanism, and the driving mechanism is used to drive the cleaning end to move;

[0009] A lateral displacement mechanism, which is arranged outside the driving mechanism and performs lateral cleaning along a preset path;

[0010] A longitudinal displacement mechanism is arranged on the transverse displacement mechanism through a connecting end, and the longitudinal displacement mechanism performs longitudinal cleaning along a preset path through a guiding mechanism.

[0011] As a preferred embodiment, the driving mechanism includes a reciprocating screw and a driving motor, the reciprocating screw is rotatably connected inside the mounting mechanism, and the driving motor is installed outside the mounting mechanism and its output end is fixedly connected to one end of the reciprocating screw.

[0012] As a preferred embodiment, the lateral displacement mechanism includes a lateral movement block, which is threadedly connected to the outside of the reciprocating screw, one side of the lateral movement block is fixedly connected to a fixed sleeve, the interior of the fixed sleeve is slidably connected to a movable block, and a limiting spring is arranged between one end of the movable block and the inner wall of the fixed sleeve.

[0013] As a preferred embodiment, the connecting end includes a connecting block, two grooves are provided inside the connecting block, sliding rods are provided inside the grooves, and grooves are provided on the outside of the connecting block and on the outside of the grooves, and the grooves are communicated with the outside through the grooves.

[0014] As a preferred embodiment, the longitudinal displacement mechanism includes a longitudinal displacement block, two connecting rods extending from one side of the longitudinal displacement block, the connecting rods extending to the interior of the corresponding groove body through the grooves and being slidably connected to the outer side of the sliding rod, and a return spring is sleeved on the outer side of the sliding rod and between the connecting rod and the inner wall of the groove body.

[0015] As a preferred embodiment, one side of the movable block and the longitudinal movement block is fixedly connected with an arc plate, the inner circle of the arc plate is equidistantly provided with matching wheels, and the matching wheels are in conflict with the outer side of the guide rod.

[0016] As a preferred embodiment, the guide mechanism comprises a guide rod, the outer side of the guide rod is provided with a protrusion of a cam-shaped structure, and both ends of the protrusion smoothly transition with the outer side of the guide rod in a chamfered shape.

[0017] As a preferred embodiment, a fixing plate is installed on the transverse moving block, and bristles are installed on the bottom of the fixing plate and the bottom of the longitudinal moving block.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] The utility model drives the reciprocating screw to rotate through the work of the driving motor, and uses the reciprocating screw to drive the transverse block to move. Due to the transmission relationship between the guide rod and the reciprocating screw, the guide rod will also rotate, but the step on the surface of the guide rod will be offset by the movement of the movable block. Therefore, the transverse block has both limiting and moving work, so that the movement of the transverse block can clean the surface of the passing circuit board horizontally, and when the longitudinal block contacts the guide rod, and the longitudinal block and the guide rod are in hard contact, the step on the guide rod will drive the longitudinal block to move, and the longitudinal block will drive the connecting rod to move when moving, so that the longitudinal block can clean the surface of the passing circuit board vertically. Through this arrangement, the entire cleaning step of the present structure can form a "cross"-like structure. This cleaning method can effectively remove impurities at the steps of the circuit board, thereby greatly improving the cleaning efficiency of the circuit board surface and reducing the workload of manual inspection by the staff.

[0027] Example

[0028] refer to Figure 1 - Figure 4 The utility model provides a technical solution: including a mounting mechanism 1, and also including:

[0029] The driving mechanism is arranged inside the mounting mechanism 1. The driving mechanism is used to drive the cleaning end to move. The driving mechanism includes a reciprocating screw 2 and a driving motor 19. The reciprocating screw 2 is rotatably connected inside the mounting mechanism 1. The driving motor 19 is installed outside the mounting mechanism 1 and its output end is fixedly connected to one end of the reciprocating screw 2. The reciprocating screw 2 is driven to rotate by the driving motor 19, and its rotation mode should have forward and reverse functions.

[0030] A transverse displacement mechanism, which is arranged on the outside of the driving mechanism and performs transverse cleaning along a preset path. The transverse displacement mechanism includes a transverse displacement block 4, which is threadedly connected to the outside of the reciprocating screw 2. A fixed sleeve 7 is fixedly connected to one side of the transverse displacement block 4, and a movable block 8 is slidably connected inside the fixed sleeve 7. A limit spring 9 is arranged between one end of the movable block 8 and the inner wall of the fixed sleeve 7. The transverse displacement block 4 has the function of moving by rotating the reciprocating screw 2, and the movable block 8 can move its position by squeezing the limit spring 9 when moving, and the movable block 8 can also be reset by the limit spring 9;

[0031] A longitudinal displacement mechanism, which is arranged on the transverse displacement mechanism through a connecting end, and the longitudinal displacement mechanism performs longitudinal cleaning along a preset path through a guiding mechanism, and the connecting end includes a connecting block 5, and two grooves 10 are provided inside the connecting block 5, and sliding rods 11 are provided inside the grooves 10, and slots 13 are provided on the outside of the connecting block 5 and located on the outside of the grooves 10, and the grooves 10 are communicated with the outside through the slots 13, and the longitudinal displacement mechanism includes a longitudinal displacement block 6, and two connecting rods 12 extend from one side of the longitudinal displacement block 6, and the connecting rods 12 extend to the inside of the corresponding grooves 10 through the slots 13 and are slidably connected with the outside of the sliding rods 11, and a return spring 14 is sleeved on the outside of the sliding rod 11 and between the connecting rod 12 and the inner wall of the groove 10, when the longitudinal displacement block 6 moves, the connecting rod 12 will also move with it, and the connecting rod 12 will squeeze the return spring 14 when moving, so the longitudinal displacement block 6 can realize the return operation through the return spring 14 while having the moving function;

[0032] Based on the above statements and supplements, the following principles are explained:

[0033] The various mechanisms of the device are arranged on the mounting mechanism 1, and the cleaning sequence is as follows: first, the driving mechanism starts to work, driving the lateral displacement mechanism to start moving, so as to realize the lateral sweep of the circuit board; then, the longitudinal displacement mechanism starts to move through the movement of the lateral displacement mechanism and cooperates with the guide mechanism so that the longitudinal displacement mechanism can realize the working purpose of longitudinal cleaning;

[0034] Among them, one side of the movable block 8 and the longitudinal movement block 6 is fixedly connected with an arc plate 15, and the inner circle of the arc plate 15 is equidistantly provided with matching wheels 16, and the matching wheels 16 are in conflict with the outer side of the guide rod 3;

[0035] Based on the above statements and supplements, the following principles are explained:

[0036] The mating wheel 16 can move by fitting the outer side of the guide rod 3 due to its own rotatable characteristics, and multiple mating wheels 16 can ensure that even when the mating wheel 16 is on the step-shaped protrusion on the guide rod 3, it will fit tightly due to the limit spring 9 and the return spring 14, and will not shift.

[0037] The guide mechanism includes a guide rod 3, the outer side of the guide rod 3 is provided with a cam-shaped protrusion, and the two ends of the protrusion are smoothly transitioned to the outer side of the guide rod 3 in a chamfered shape;

[0038] Based on the above statements and supplements, the following principles are explained:

[0039] The guide rod 3 can utilize the characteristics of its own cam-shaped structure to resist and drive the longitudinal displacement mechanism;

[0040] Among them, a fixed plate 17 is installed on the transverse moving block 4, and bristles 18 are installed on the bottom of the fixed plate 17 and the bottom of the longitudinal moving block 6;

[0041] Based on the above statements and supplements, the following principles are explained:

[0042] The purpose of sweeping and cleaning can be achieved by providing the bristles 18 .

[0043] Working principle:

[0044] like Figure 1 - Figure 4As shown, when the present structure is in use, the reciprocating screw 2 is driven to rotate by the operation of the driving motor 19, and the rotation of the reciprocating screw 2 drives the lateral block 4 to move. When the lateral block 4 moves, the arc plate 15 and the matching wheel 16 on one side thereof will fit the surface of the guide rod 3, and the step on the surface of the guide rod 3 will also be offset by the movement of the movable block 8, so that the lateral block 4 has both the limiting function and the moving function. In this way, the movement of the lateral block 4 can clean the surface of the circuit board passing by horizontally, and then the longitudinal block 6 is moved to the protrusion of the guide rod 3. Because the longitudinal block 6 is in hard contact with the guide rod 3, The step on the guide rod 3 will drive the longitudinal movement block 6 to move, and the longitudinal movement block 6 will drive the connecting rod 12 to move when moving, so that the longitudinal movement block 6 can longitudinally clean the surface of the passing circuit board. While the longitudinal movement block 6 moves, the connecting rod 12 squeezes the reset spring 14, thereby providing a rebound force for the longitudinal movement block 6. Through this arrangement, the entire cleaning step of the present structure can form a "cross" structure. This cleaning method can effectively remove impurities at the steps of the circuit board, thereby greatly improving the cleaning efficiency of the circuit board surface and reducing the workload of manual inspection by staff.
