Description

Technical Field

[0001] The present invention relates to the field of circuit board electroplating equipment, and particularly to an electroplating process for the production of circuit boards for new energy vehicles. Background Art

[0002] For the electroplating work of a circuit board, the circuit board needs to be used as a cathode plate and connected to an electroplating bath. After electrically connecting the cathode plate and the anode plate to the same circuit, an electroplating solution is introduced into the electroplating bath, which can effectively electroplate the circuit board.

[0003] An electroplating device for a printed circuit board disclosed in Chinese Patent CN105063709A hides the electroplating solution spraying pipe inside the anode plate, effectively shortening the distance between the anode plate and the circuit board, improving the effective contact effect between the continuously output electroplating solution and the surface of the circuit board, and greatly improving the electroplating efficiency of the circuit board. However, due to the too-close distance between the electroplating solution spraying pipe and the circuit board, the electroplating solution sprayed from the electroplating solution spraying pipe is likely to directly cover the surface of the circuit board before it has time to diffuse around, resulting in uneven coverage of the electroplating solution between the area of the circuit board surface close to the electroplating solution spraying pipe and the area of the circuit board surface far from the electroplating solution spraying pipe, still affecting the uniformity of the electroplating thickness on the surface of the circuit board.

[0004] In addition, due to the too-close distance between the anode plate and the circuit board, the impurities suspended between the anode plate and the circuit board cannot leave the area between the anode plate and the circuit board in time, resulting in easy large-area attachment of impurities on the surface of the anode plate, affecting the working efficiency of the anode plate in electroplating operations. Summary of the Invention

[0005] In order to overcome the drawbacks that the distances between the anode plate and the electroplating solution spraying pipe and the circuit board are too close, resulting in untimely diffusion of the electroplating solution and uneven coverage of the electroplating solution, and the easy large-area attachment of impurities on the surface of the anode plate, affecting the working efficiency of the anode plate in electroplating operations, the present invention provides an electroplating process for the production of circuit boards for new energy vehicles.

[0052] As Figure 5 and Figure 6As shown in the figure, the reciprocating translation mechanism includes a C-shaped vertical rod 41, a connecting rod 42, a telescopic cylinder 43, a first slider 44, and an elastic ejecting member; a first slider 44 is slidably connected to each of the upper and lower sides of the mounting plate 3; the same C-shaped vertical rod 41 is bolted between each pair of upper and lower corresponding first sliders 44; a connecting rod 42 is bolted between the upper ends of all the C-shaped vertical rods 41; a telescopic cylinder 43 is bolted to the upper side of the sliding cross bar 23; the telescopic end of the telescopic cylinder 43 is fixedly connected to the connecting rod 42; an elastic ejecting member is connected to each of all the first sliders 44; the same rotating spray assembly is connected between each pair of upper and lower corresponding elastic ejecting members.

[0053] As Figure 9 and Figure 10 shown in the figure, the elastic ejecting member is composed of a second slider 45 and a spring member 46; a second slider 45 is slidably connected to the first slider 44; a spring member 46 is fixedly connected between the second slider 45 and the first slider 44; the second slider 45 is connected to the rotating spray assembly.

[0054] As Figures 9 - 13 shown in the figure, the rotating spray assembly includes a rotating pipe 6, a forward soft pad 61, a reverse soft pad 62, a baffle 7, and a brush roller 8; a rotating pipe 6 is rotatably connected between each pair of upper and lower corresponding second sliders 45; a main through groove 601 structure is provided inside the rotating pipe 6; a liquid delivery pipe 51 is rotatably connected to each of the upper and lower ends of the main through groove 601; a number of first spray holes 603 structures communicating with the main through groove 601 are provided around the rotating pipe 6; a forward soft pad 61 is fixedly connected to the outer end of each first spray hole 603, and the forward soft pad 61 is arranged as a semi-closed structure with the opening facing counterclockwise in a top view; a number of second spray holes 605 structures communicating with the main through groove 601 are provided around the rotating pipe 6; a reverse soft pad 62 is fixedly connected to the outer end of each second spray hole 605, and the reverse soft pad 62 is arranged as a semi-closed structure with the opening facing clockwise in a top view; the first spray holes 603 and the second spray holes 605 are alternately distributed in the up and down direction; a first secondary through groove 602 structure is provided between each group of vertically aligned first spray holes 603; a second secondary through groove 604 structure is provided between each group of vertically aligned second spray holes 605; a baffle 7 is rotatably connected to the outer surface of the rotating pipe 6; the middle part of the baffle 7 is arranged as a semi-circular structure with the opening facing the insertion plate 10; the upper end of the baffle 7 is bolted to the upper second slider 45 through a fixing block 71; a brush roller 8 is rotatably connected to the outer surface of the baffle 7; a number of liquid outlet grooves 81 structures are provided around the brush roller 8.

[0055] As Figure 13 and Figure 14As shown in the figure, the output control component includes an inner tube 9, an electric push rod 91 and a lining sleeve 92; the inner tube 9 is inserted into the main through groove 601; several liquid through holes 901 are formed around the inner tube 9; the upper end of the inner tube 9 is rotatably connected to the lining sleeve 92; the electric push rod 91 is bolted inside the upper liquid delivery pipe 51; the telescopic end of the electric push rod 91 is fixedly connected to the lining sleeve 92.

[0056] The forward electroplating operation of this electroplating equipment:

[0057] In the initial state, each rotating spray component is respectively located in the vertical groove 301 on the right side of a corresponding anode plate 31. At this time, each liquid through hole 901 of the inner tube 9 is respectively connected to a corresponding first spray hole 603.

[0058] First, pull out the plug board 10 from the electroplating bath 1. After installing the circuit board body 11 on the plug board 10, insert the plug board 10 back into the electroplating bath 1, and electrically connect the anode connector 321 and the cathode connector 101 in the same circuit, so that the circuit board body 11 connected to the cathode connector 101 serves as the cathode plate, and together with the anode plate 31 connected to the anode connector 321, an electroplating circuit body is formed.

[0059] The control driving motor 22 drives the bidirectional lead screw 21 to rotate. The bidirectional lead screw 21 drives the two sliding cross bars 23 to move closer to each other in the direction of the plug board 10, shortening the distance between the anode plate 31 and the circuit board body 11. The liquid inlet 501 of the integrated tube 5 is externally connected to an electroplating solution delivery device, and the electroplating solution delivery device transports the electroplating solution to the integrated tube 5 through the liquid inlet 501. The electroplating solution enters the main through groove 601 of each rotating tube 6 along the liquid delivery pipe 51.

[0060] As the electroplating solution is continuously poured into the main through groove 601, the electroplating solution is respectively poured into the first secondary through groove 602 connected to each first spray hole 603 through each liquid through hole 901, and then sprayed out through each first spray hole 603. At this time, the electroplating solution sprayed out from the first spray hole 603 can only be sprayed in a counterclockwise direction at a top view angle along the opening direction of the forward soft pad 61. The rotating tube 6 rotates clockwise at a top view angle under the thrust generated during the spraying process of the electroplating solution. The sprayed electroplating solution is blocked by the baffle 7 and can only spread towards the circuit board body 11 on the plug board 10. After passing through the liquid outlet groove 81, the electroplating solution sprayed clockwise at a top view angle will spread uniformly to the left in a forward rippling diffusion manner, covering each area on the surface of the circuit board body 11 one by one, avoiding the phenomenon that the electroplating solution is concentrated and covers the area on the surface of the circuit board body 11 that is closer, improving the diffusion range and diffusion uniformity of the electroplating solution after spraying, and performing efficient electroplating work on the surface of the circuit board body 11.

[0061] The reverse electroplating operation of this electroplating equipment:

[0062] After the swirl tube 6 sprays the electroplating solution onto the surface of the circuit board body 11 in a way of positive-direction ripple diffusion, it is necessary to regularly adjust the position of the rotary spraying assembly.

[0063] First, the telescopic end of the telescopic cylinder 43 pushes the connecting rod 42 to drive the first slider 44 connected to the C-shaped vertical rod 41 to move leftward along the mounting plate 3. During the process that the first slider 44 drives the second slider 45 connected thereto to move leftward, the second slider 45 is pushed out toward the circuit board body 11 along the inclined surface structure on the left side wall of the vertical groove 301. When the second slider 45 drives the spring member 46 to be compressed, the second slider 45 pushes the rotary spraying assembly out of the vertical groove 301. After the rotary spraying assembly moves into the vertical groove 301 on the left side with the mounting plate 3 of the first slider 44 moving leftward, the compressed spring member 46 drives the second slider 45 to reset, and the second slider 45 drives the rotary spraying assembly to fall into the vertically moving and aligned vertical groove 301, realizing the transfer of the rotary spraying assembly from the vertical groove 301 on the right side of the anode plate 31 to the vertical groove 301 on the left side of the anode plate 31, and completing the position replacement work of the rotary spraying assembly.

[0064] During the process of the rotary spraying assembly performing the position replacement work, the telescopic end of the electric push rod 91 pushes the inner liner 92 to drive the inner tube 9 to move downward along the main through groove 601, so that each liquid through hole 901 of the inner tube 9 is respectively communicated with a corresponding second spray hole 605. After the electroplating solution enters the main through groove 601 of each swirl tube 6 along the liquid delivery pipe 51, the electroplating solution is respectively poured into the second sub-through groove 604 communicated with each second spray hole 605 through each liquid through hole 901, and then sprayed out through each second spray hole 605. At this time, the electroplating solution sprayed out from the second spray hole 605 can only be sprayed out in a clockwise direction from a top view angle along the opening direction of the reverse soft pad 62. The swirl tube 6 rotates counterclockwise from a top view angle under the thrust generated during the spraying process of the electroplating solution, and the sprayed electroplating solution is blocked by the baffle 7 and can only diffuse toward the circuit board body 11 on the plug board 10. After the electroplating solution rotating counterclockwise from a top view angle passes through the liquid outlet groove 81, it will diffuse uniformly to the right in a way of reverse-direction ripple diffusion, covering one by one the areas on the surface of the circuit board body 11 where the electroplating solution diffuses less, further improving the diffusion range and diffusion uniformity of the electroplating solution after spraying.

[0065] Self-cleaning work of this electroplating equipment:

[0066] During the process of the rotary spraying assembly performing the position replacement work, the brush roller 8 moving with the first slider 44 rolls closely on the surface of the anode plate 31 when crossing the anode plate 31, and the impurities covering the surface of the anode plate 31 are timely removed by the brush roller 8, avoiding the influence of the electroplating work efficiency of the entire electroplating tank 1 due to a large area of impurities covering the surface of the anode plate 31, and completing the self-cleaning work.

[0067] The above has introduced the present application in detail. Specific examples are used in this text to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
