Description

Technical Field

[0001] The present application relates to the technical field of high-frequency board production equipment, and particularly relates to a cleaning device for high-frequency board production. Background Art

[0002] A high-frequency board is a special circuit board with a relatively high electromagnetic frequency, also known as a high-frequency circuit board, PCB, ultra-thin circuit board, etc. It has the advantages of high wiring density, light weight, thin thickness, good bendability, etc., and is commonly used in fields such as automotive anti-collision systems, satellite systems, and radio systems.

[0003] In the production process of high-frequency boards, there is a cleaning process to clean the powder residues, stains, etc. on the surface of the high-frequency boards. The Chinese utility model patent document with the publication number CN216174824U discloses a cleaning device for circuit board production, including a bottom cabinet and a cabinet cover. A cleaning box is slidably installed up and down in the bottom cabinet, and the cleaning box can hold cleaning liquid. A sieve box is installed on the cabinet cover, and the circuit board to be cleaned is placed in the sieve box. The cleaning box moves up and down to clean the circuit board.

[0004] Since the circuit boards are stacked and placed in the sieve box, during the up and down movement of the cleaning box, the circuit boards may also slide, so scratches may occur between the circuit boards, thereby causing defects such as scratches on the surface of the circuit boards. Summary of the Invention

[0005] In order to reduce damage to the product surface during cleaning, the present application provides a cleaning device for high-frequency board production.

[0006] The present application adopts the following technical solutions:

[0007] A cleaning device for high-frequency board production, including a box body, a cover plate for covering the box body, a fixture for clamping a high-frequency board, and a liquid flushing assembly provided on the box body. The fixture is installed in the box body, a driving source for driving the fixture to rotate in the box body is installed on the box body, the fixture is located on the liquid outlet path of the liquid flushing assembly, and a liquid outlet pipe is provided on the box body or the cover plate.

[0008] By adopting the above technical solutions, during cleaning, the high-frequency board is clamped by the fixture. After the cover plate covers the box body, the liquid flushing assembly flushes the fixture, so as to be able to clean the high-frequency board. When there is more cleaning liquid on the box body, it can overflow from the liquid outlet pipe. By driving the fixture to rotate through the driving source, the flushing effect on the high-frequency board can be improved, and the high-frequency board is positioned by the fixture, reducing the occurrence of scratches between the high-frequency boards.

[0009] Optionally, the fixture includes two connecting plates and two connecting rods connected between the two connecting plates. A plurality of clamping blocks are provided on the outer wall of the connecting rod. The clamping blocks are spaced apart along the length direction of the connecting rod. A card slot for inserting a high-frequency board is formed in the clamping block, and the high-frequency board can be clamped between two opposite clamping blocks.

[0010] By adopting the above technical solution, the high-frequency board can be inserted between two opposite clamping blocks, thereby positioning the high-frequency board. A plurality of clamping blocks are installed on the connecting rod, so that a plurality of high-frequency boards can be cleaned simultaneously. The high-frequency boards are positioned one by one through the clamping blocks, making it not easy to scratch the surface of the high-frequency board during the flushing process.

[0011] Optionally, two auxiliary rods are further connected between the two connecting plates. When the connecting rods are located on both sides of the high-frequency board, the two auxiliary rods are respectively located above and below the high-frequency board. Both the auxiliary rod and the connecting rod are rotatably connected to the connecting plate, and both the connecting rod and the auxiliary rod are detachably connected to the connecting plate; the clamping blocks are also installed on the two auxiliary rods. When the high-frequency board is clamped to the clamping blocks on the two connecting rods, the clamping blocks on the auxiliary rods are staggered from the high-frequency board; a trigger member is provided on the box body. When the driving source drives the fixture to rotate, the trigger member can drive the connecting rod and the auxiliary rod to rotate, so that when the clamping blocks on the connecting rod gradually separate from the high-frequency board, the clamping blocks on the auxiliary rod can gradually be clamped to the high-frequency board.

[0012] By adopting the above technical solution, clamping blocks are installed on both the connecting rod and the auxiliary rod. When the high-frequency board is clamped to the two clamping blocks on the connecting rod, the clamping blocks on the auxiliary rod are staggered from the high-frequency board. When the fixture rotates, under the action of the trigger member, the connecting rod and the auxiliary rod can rotate, so that the clamping blocks on the connecting rod are separated from the high-frequency board, and the clamping blocks on the auxiliary rod can be clamped to the high-frequency board. Therefore, the position where the high-frequency board was originally clamped by the clamping blocks on the connecting rod can be exposed for cleaning, thereby improving the cleaning effect of the high-frequency board.

[0013] Optionally, a connecting seat is rotatably connected to one of the connecting plates, and a positioning seat is rotatably connected to the other connecting plate. The connecting seat and the positioning seat correspond to each other, and the connecting rod and the auxiliary rod are connected between the corresponding positioning seat and connecting seat; one end of the connecting seat has a part extending beyond the surface of the connecting plate and is coaxially connected with a driving gear. The trigger member includes a trigger gear installed on the inner wall of the box body, and the driving gear meshes with the trigger gear.

[0014] By adopting the above technical solution, the driving gear meshes with the trigger gear, so that during the rotation of the connecting plate, the driving gear can rotate synchronously, thereby driving the connecting rod and the auxiliary rod to rotate synchronously.

[0015] Optionally, the driving source includes a driving rod rotatably connected to a side of the box body away from the trigger gear and a first element for driving the driving rod to rotate, and the driving rod is connected to the adjacent connecting plate.

[0016] By adopting the above technical solution, the first element drives the driving rod to rotate, thereby driving the connecting plate to rotate and realizing the rotation of the fixture.

[0017] Optionally, an installation cavity is formed on a side of the connection seat facing the positioning seat, and an elastic member is installed in the installation cavity. A plugging cavity is formed on a side of the positioning seat facing the connection seat. One ends of the auxiliary rod and the connecting rod can be plugged into the installation cavity, and under the action of the elastic member, the other ends of the auxiliary rod and the connecting rod can be plugged into the plugging cavity.

[0018] By adopting the above technical solution, when the connecting rod and the auxiliary rod are installed, one end is plugged into the installation cavity, the elastic member is compressed, and then the other end is plugged into the plugging cavity. Under the action of the elastic member, the end of the connecting rod or the auxiliary rod abuts against the plugging cavity, thereby realizing the installation of the connecting rod and the auxiliary rod.

[0019] Optionally, through holes penetrating both sides are formed on both the auxiliary rod and the connecting rod. When the auxiliary rod or the connecting rod moves to a position close to the liquid flushing assembly, the cleaning liquid can pass through the through holes.

[0020] By adopting the above technical solution, when the cleaning liquid flushes out from the liquid flushing assembly, the flowing liquid can also pass through the through holes, thereby improving the liquid flushing and cleaning effect on the high-frequency board.

[0021] Optionally, a push rod is slidably arranged on the outer wall of the box body and a power member for driving the push rod to slide. The push rod can penetrate through the positioning seat and extend into the plugging cavity. When the push rod slides, it can push the connecting rod or the auxiliary rod to slide reciprocally.

[0022] By adopting the above technical solution, during the liquid flushing and cleaning process, the connecting rod or the auxiliary rod can slide reciprocally, thereby increasing the range that the high-frequency board can be cleaned and further improving the cleaning effect.

[0023] Optionally, the liquid flushing assembly includes a liquid flushing seat arranged on the inner wall of the box body and a liquid supply pipe connected to the liquid flushing seat. The liquid flushing seat is uniformly provided with punching holes.

[0024] By adopting the above technical solution, punching holes are formed on the liquid flushing seat, and the cleaning liquid of the liquid supply pipe can flush out from the punching holes, thereby flushing the high-frequency board.

[0025] In summary, the present application includes at least one of the following beneficial effects:

[0026] 1. The high-frequency board is placed in the box body through a fixture. After the upper cover plate is closed, the high-frequency board is rinsed through the liquid flushing component. During the flushing process, the fixture can rotate to improve the flushing effect;

[0027] 2. The clamping blocks on the connecting rod and the auxiliary rod can alternately position the high-frequency board, so that the positions covered by the clamping blocks can be exposed for cleaning. Description of the Drawings

[0033] The following further describes the present application in detail with reference to the attached Figures 1-4 drawings.

[0034] An embodiment of the present application discloses a cleaning device for the production of high-frequency boards. Referring to Figure 1 , the cleaning device includes a box body 1, a cover plate 2, a fixture 3 and a liquid flushing component 4. The cover plate 2 is used to cover the box body 1. The fixture 3 is installed in the box body 1 and the fixture 3 is used to clamp the high-frequency board to be cleaned. The liquid flushing component 4 is installed in the box body 1, and the liquid flushing component 4 flushes out the cleaning liquid and cleans the high-frequency board. In order to facilitate the covering or opening of the box body 1 by the cover plate 2, the cleaning device further includes a frame body. The cover plate 2 moves up and down on the frame body by means of a cylinder or the like. The box body 1 is located directly below the cover plate 2, and when the cover plate 2 moves downward, it can cover the box body 1.

[0035] Referring to Figure 2 andFigure 3 , preferably, the flushing component 4 is installed on the bottom surface of the box body 1, and the fixture 3 is located directly above the flushing component 4. A driving source 5 is also installed on the box body 1 to drive the fixture 3 to rotate, so that the flushing component 4 can better flush the high-frequency board. An outlet pipe 6 is also installed on the box body 1 or the cover plate 2, so that when there is too much cleaning liquid in the box body 1, it can overflow. The outlet pipe 6 is preferably installed on the side wall at the upper end of the box body 1, and the position of the connection between the outlet pipe 6 and the box body 1 is higher than the position of the fixture 3.

[0036] The flushing component includes a flushing seat 41 installed on the bottom surface of the box body 1 and a liquid supply pipe 42 connected to the flushing seat 41. The liquid supply pipe 42 is connected to the lower surface of the flushing seat. The upper surface of the flushing seat is coplanar with the inner bottom surface of the box body 1, and a plurality of punching holes 43 are evenly formed on the upper surface of the flushing seat. The liquid supply pipe 42 is connected to the water source of the cleaning liquid, and the cleaning liquid is supplied into the flushing seat by means of a water pump or the like, and flushes upward through the punching holes 43, so as to flush the high-frequency board. When the liquid level in the box body 1 gradually rises, the cleaning liquid coming out of the punching holes 43 always flows upward, so as to continuously flush the high-frequency board.

[0037] Refer to Figure 3 and Figure 4 , the fixture 3 includes two connecting plates 31 and a connecting rod 32 connected between the two connecting plates 31. There are two connecting rods 32 installed. A plurality of clamping blocks 33 are installed on the connecting rod 32, and the clamping blocks 33 are arranged at intervals along the length direction of the connecting rod 32. Each clamping block 33 is provided with a clamping groove 34, and the high-frequency board can be inserted between the two clamping blocks 33 through the clamping groove 34, so as to position the high-frequency board. An elastic layer can be bonded to the inner wall of the clamping groove 34 to improve the positioning effect on the high-frequency board. The driving source 5 includes a driving rod 51 rotatably connected to one side wall of the box body 1 and a first element 52 installed on the outer wall of the box body 1 and used to drive the driving rod 51 to rotate. The first element 52 can be a stepping motor and is connected to the driving rod 51. The driving rod 51 and the box body 1 can use an existing rotary sealing structure to improve the sealing performance. One end of the driving rod 51 extends into the box body 1 and is fixedly connected to the connecting plate 31, so that when the driving rod 51 rotates, it can drive the connecting plate 31 to rotate.

[0038] Further, an auxiliary rod 7 is also installed between the two connecting plates 31. The auxiliary rod 7 and the connecting rod 32 are staggeredly distributed along the circumferential direction of the connecting plate 31. A clamping block 33 with a clamping groove 34 is also installed on the auxiliary rod 7. The high-frequency board is located between the two connecting rods 32 and the two auxiliary rods 7. When the clamping blocks 33 on the connecting rods 32 are clamped on both sides of the high-frequency board, the two auxiliary rods 7 are respectively located at the upper and lower positions of the high-frequency board, and at this time, the clamping blocks 33 on the auxiliary rods 7 are separated from the high-frequency board. The auxiliary rod 7 and the connecting rod 32 are both detachably installed on the connecting plate 31, which is convenient for taking and placing the high-frequency board. The auxiliary rod 7 and the connecting rod 32 are rotatably connected between the two connecting plates 31, and a trigger member 8 is installed in the box body 1. When the driving source 5 drives the fixture 3 to rotate, the connecting rod 32 and the auxiliary rod 7 can also be driven to rotate under the action of the trigger member 8. During the rotation of the connecting rod 32 and the auxiliary rod 7, the clamping block 33 on the connecting rod 32 is gradually separated from the high-frequency board, and the clamping block 33 on the auxiliary rod 7 gradually approaches the high-frequency board and is clamped on the high-frequency board. Thus, during the rotation of the fixture 3, the part originally covered by the clamping block 33 on the connecting rod 32 can be exposed, so that it can be cleaned, improving the cleaning effect.

[0039] Refer to Figure 2 and Figure 3 , a connecting seat 9 is rotatably connected to a connecting seat 9 by means of a bearing or the like, and a positioning seat 10 is rotatably connected to the other connecting seat 9. The connecting seats 9 and the positioning seats 10 are in one-to-one correspondence, and one end of the connecting rod 32 and the auxiliary rod 7 is connected to the positioning seat 10, and the other is connected to the connecting seat 9. The driving source 5 is connected to the connecting plate 31 on which the positioning seat 10 is installed.

[0040] One end of the connecting seat 9 has a part extending beyond the surface of the connecting plate 31, and a driving gear 11 is coaxially fixed. The trigger member 8 includes a trigger gear 81 installed on the inner wall of the box body 1, and the trigger gear 81 meshes with the driving gear 11. When the driving source 5 drives the connecting plate 31 to rotate, the connecting rod 32 and the auxiliary rod 7 can be driven to rotate.

[0041] Refer to Figure 3 and Figure 4, one end of the connecting seat 9 facing the positioning seat 10 is provided with an installation cavity 12, and the ends of the connecting rod 32 and the auxiliary rod 7 can be inserted into the installation cavity 12. An elastic member 13 is also installed in the installation cavity 12, and the elastic member 13 is a spring. When the connecting rod 32 or the auxiliary rod 7 is inserted into the installation cavity 12, the spring can be compressed. One end of the positioning seat 10 facing the connecting seat 9 is provided with a plugging cavity 14. After one end of the connecting rod 32 or the auxiliary rod 7 is inserted into the installation cavity 12, the elastic member 13 is compressed, and the other end can be aligned with the plugging cavity 14 and inserted into the plugging cavity 14 under the action of the elastic member 13. When it is necessary to pick up and place the high-frequency board, the uppermost auxiliary rod 7 or the connecting rod 32 can be removed. For the convenience of the installation and disassembly of the connecting rod 32 and the auxiliary rod 7, the connecting rod 32 and the auxiliary rod 7 can preferably be made of engineering plastic material with a certain elasticity.

[0042] Both the connecting rod 32 and the auxiliary rod 7 are provided with through holes 15, and the through holes 15 penetrate through both sides of the connecting rod 32 or the auxiliary rod 7. When the connecting rod 32 or the auxiliary rod 7 is at the lowermost position, the through hole 15 faces upward. The liquid coming out of the liquid injection assembly 4 can flow downward through the through hole 15, thereby increasing the range that can be cleaned. Further, a push rod 16 is slidably inserted through the outer wall of the box body 1, and the push rod 16 has a round rod structure. A power member 17 is also installed on the outer wall of the box body 1. The power member 17 can be a cylinder and is connected to the push rod 16. One end of the positioning seat 10 is provided with a through hole 18 for the push rod 16 to be inserted, and the through hole 18 is communicated with the plugging cavity 14. Corresponding to the position of the lowermost positioning seat 10, the push rod 16 can be driven by the power member 17 to extend into the plugging cavity 14 and push the connecting rod 32 or the auxiliary rod 7 to slide reciprocally, and the sliding displacement cannot cause it to break away from the plugging cavity 14. The reciprocating movement of the connecting rod 32 or the auxiliary rod 7 can change the position of the through hole 15 reciprocally, thereby improving the cleaning effect. When the clamp 3 needs to rotate, the push rod 16 disengages from the positioning seat 10.

[0043] The implementation principle of a cleaning device for high-frequency board production in an embodiment of the present application is as follows: Remove the uppermost auxiliary rod 7, then insert the high-frequency board between two opposite clamping blocks 33, and then install the auxiliary rod 7 back. When the connecting rod 32 or the auxiliary rod 7 rotates to the position corresponding to the push rod 16 driven by the driving source 5 to drive the clamp 3 to rotate, the push rod 16 drives it to slide reciprocally, and the push rod 16 disengages from the positioning seat 10, and the clamp 3 can continue to rotate. During this process, the liquid injection assembly 4 always maintains the liquid output state, so that the high-frequency board can be continuously rinsed.

[0044] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
