Description

Technical Field

[0001] The invention relates to the technical field of circuit board electroplating, and in particular to an immersion device for circuit board electroplating. Background Art

[0002] After the circuit board has gone through the exposure and development process, the printed circuits on the circuit board can be fully displayed. After exposure and development, the copper plate of the non-circuit part will be covered by a dry film, while the copper surface of the circuit part will be exposed. The next step is to electroplate and thicken the exposed copper circuit and protect it with tin plating on the outer layer. The general electroplating method is to clamp and hang the circuit boards in batches, and then move the circuit boards up and down and forward and backward through a mobile rack, so that the circuit boards pass through multiple slots such as degreasing, water washing, micro-etching, copper plating, acid dipping and tin plating. Since the equipment moves up and down and forward and backward, the clamped and hung circuit boards and the mobile rack are kept on the same plane. During the follow-up movement, the lower half of the board shakes back and forth very much. The liquid medicine originally remaining in the upper half of the board will accelerate the downward flow and migration of the liquid medicine remaining in the upper half of the board due to the swing of the board, and this continuous shaking process will speed up the downward migration of the liquid medicine remaining on the board and the deposition speed in the edge area of ​​the lower half; and the back and forth shaking of the board during the movement will also cause a slight deformation in the area of ​​the clamped part of the board, and the greater the shaking amplitude of the board, the more likely the internal structure of the board will crack. Summary of the invention

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] The present invention specifically discloses an immersion device for circuit board electroplating, such as Figure 1-Figure 4As shown, it includes: a support driving frame 1 with an electric guide rail installed on the frame body, the electric guide rail is installed on the top of the support driving frame 1, and is used to drive a moving frame 3 connected to the top of the support driving frame 1 to move, and the moving frame 3 is driven by the electric guide rail to move horizontally forward and backward. A plurality of immersion tanks 2 are evenly installed in the middle of the support driving frame 1. The number of immersion tanks 2 is set according to the number of processing steps of the sample 500. The main processing steps of the sample 500 include degreasing, water washing, micro-etching, copper plating, acid immersion and tinning, and the liquid used in each process is not consistent. Therefore, a cleaning tank needs to be added in the middle of the connection between the previous and subsequent processes. After cleaning the residual liquid in the previous soaking tank 2, it enters the next soaking tank 2. A lifting device 4 is installed on the moving frame 3. The lifting device 4 is composed of a motor, a screw rod and a sliding plate. The motor drives the screw rod to rotate, thereby causing the sliding plate to move up / down. A mounting shell 5 is fixedly installed at the bottom of the sliding plate of the lifting device 4. A first motor 6 is installed on the mounting shell 5. Four rotating plates 7 are evenly spaced and rotated at the bottom of the mounting shell 5. An active rotating rod 8 is installed inside the mounting shell 5 for rotation. Figure 4 As shown, a bevel gear set 9 is arranged between the rotating plate 7 and the active rotating rod 8 for transmission. Four bevel gears are fixedly connected to the active rotating rod 8. Bevel gears are fixedly installed on the rotating center of the four rotating plates 7. The bevel gears on the active rotating rod 8 and the bevel gears on the rotating plate 7 are meshed with each other, so that after the active rotating rod 8 is rotated, the four rotating plates 7 can be rotated synchronously. To realize the rotation of the active rotating rod 8, the first motor 6 drives the active rotating rod 8 to rotate through the worm gear set 10. The worm wheel is installed on the active rotating rod 8, and the worm is driven to rotate by the first motor 6. After the worm and worm wheel are meshed, the active rotating rod 8 can be rotated. A self-locking clamp 11 for clamping the sample 500 is provided on the rotating plate 7. The clamping and releasing actions of the self-locking clamp 11 are completed by a clamp driving device installed on the side wall of the supporting foot 101 of the supporting driving frame 1.

[0044] Specifically, according to Figure 1 As shown, after the movable frame 3 is moved to the side of the frame by the supporting driving frame 1, the mounting shell 5 is lowered by the lifting device 4, and the self-locking jaws 11 are lowered to a specified height to prepare for clamping the sample 500. The sample 500 is placed in the self-locking jaws 11, and then the jaw driving device is used to drive the self-locking jaws 11 to lock and clamp the sample 500.

[0045] according to Figure 3As shown, after the sample 500 is clamped and fixed, after the sample 500 is lifted and before the moving frame 3 moves, the first motor 6 drives the active rotating rod 8 to rotate and then rotates the rotating plate 7 ninety degrees, so that the clamped sample 500 crosses and is perpendicular to the moving frame 3; in this way, during the movement of the moving frame 3, the sample 500 moves in a state parallel to the supporting driving frame 1, and the sample 500 can only produce slight shaking in the process of following the movement of the moving frame 3, so that the sample 500 will not be severely shaken, causing the liquid medicine to migrate downward faster to form a large amount of deposition; after the sample 500 moves to the top of the immersion tank 2, the lifting device 4 finally drives the sample 500 to descend and immerse it in the immersion tank 2.

[0046] The present invention designs the self-locking jaws 11 for clamping the sheet material to be rotatable. After the self-locking jaws 11 clamp the sheet material and rise, the turn plate 7 is rotated ninety degrees before the moving frame 3 moves, so that the sheet material is hung in a direction parallel to the moving path of the moving frame 3. In this way, the sheet material 500 will not shake during the movement, and the liquid medicine remaining on the plate body will not quickly deposit to the bottom of the plate body after the plate material shakes. At the same time, the problem of cracking of the internal structure of the plate body caused by shaking can also be avoided.

[0047] In a preferred embodiment, Figure 4-Figure 9 As shown, in order to solve the problem that multiple self-locking jaws 11 are separated from each other and cannot be driven in series during use, the self-locking jaws 11 are further improved. The self-locking jaws 11 specifically include: connecting blocks 111 symmetrically installed on both sides of the rotating plate 7, and the lower part of the connecting block 111 is slidably connected with clamping fingers 112 for clamping the template 500. There are two clamping fingers 112, which are slidably installed on the connecting block 111 in a staggered manner. The two clamping fingers 112 can clamp the template 500 when they are close to each other. A friction strip is provided at the lower part of the clamping fingers 112 to increase the gripping force. The driven worm gear 113 is rotatably connected to the connecting block 111, and the active worm 114 is rotatably connected to the side wall of the connecting block 111.

[0048] according to Figure 6 As shown, the active worm 114 is meshed with the driven worm wheel 113, and a full gear 115 is fixedly connected to the lower part of the same shaft of the driven worm wheel 113. The full gear 115 rotates with the driven worm wheel 113, and a rack wall is provided on the upper side wall of the clamping finger 112. The full gear 115 is placed between the two clamping fingers 112 and meshes with the rack wall. The clamping fingers 112 can close or separate with the rotation of the full gear 115, thereby realizing the clamping and releasing action of the clamping fingers 112. The active worm 114 on both sides are driven by a hexagonal transmission rod 116, and the hexagonal transmission rod 116 is slidably penetrated on the active worm 114 on both sides.

[0049] according to Figure 4 and Figure 5As shown, a spring 117 is sleeved on the hexagonal transmission rod 116, one end of the spring 117 is against the rotating plate 7, and the other end is connected to the hexagonal transmission rod 116. After the hexagonal transmission rod 116 is pushed to move, the hexagonal transmission rod 116 can reset itself through the spring 117. The two ends of the hexagonal transmission rod 116 are fixedly connected to the movable connecting piece 118. The movable connecting piece 118 is used in combination with two ends, one end of which is provided with a hexagonal protrusion 1181, and the other end is provided with an inner hexagonal recess that only accommodates the hexagonal protrusion 1181. The edge of the inner hexagonal recess is provided with a slope 1182, which makes it easier for the hexagonal protrusion 1181 to slide into the inner hexagonal recess.

[0050] according to Figure 4 As shown, when the hexagonal transmission rods 116 are in the same straight line, that is, after the rotating plate 7 is also in the same straight line, the rightmost hexagonal transmission rod 116 is pushed to the left, and the rightmost hexagonal transmission rod 116 slides close to another hexagonal transmission rod 116 and slides into the inner hexagonal recess through the hexagonal protrusion 1181 on the movable connecting member 118, so that the multiple hexagonal transmission rods 116 are aligned with each other and connected end to end.

[0051] Specifically, after the self-locking clamping jaws 11 are moved down by the lifting device 4, all the hexagonal transmission rods 116 are kept in the same straight line before clamping the template 500. At this time, the template 500 is placed between the clamping fingers 112, and then the side hexagonal transmission rods 116 are pushed to slide by the clamping jaw driving device. At this time, multiple hexagonal transmission rods 116 are connected together end to end by movable connecting parts 118. Therefore, when one hexagonal transmission rod 116 rotates, the other hexagonal transmission rods 116 also rotate accordingly, so that all the clamping fingers 112 are closed to complete the clamping of the template 500.

[0052] Among them, according to Figure 1 , Figure 8 and Fig. 9 As shown, the clamp driving device includes: a mounting block 121 fixedly mounted on the side wall of the supporting foot 101, a linear drive 122 fixedly mounted on the mounting block 121, the linear drive 122 is an electric guide rail, a second motor 123 is provided on the linear drive 122, the second motor 123 is driven by the linear drive 122 to move laterally, a driving rod 124 is connected to the output shaft of the second motor 123 through a coupling, and the driving rod 124 moves through the side wall of the supporting foot 101, a protective cover 120 is fixedly connected to the mounting block 121, which is used to cover and protect the second motor 123 and the linear drive 122, and an inner hexagonal recess for accommodating the hexagonal protrusion 1181 is provided at the end of the driving rod 124.

[0053] Specifically, when the self-locking clamping jaw 11 descends to the specified position and needs to clamp the sample 500, the linear driver 122 drives the second motor 123 to move the driving rod 124 and approach the hexagonal transmission rod 116 on the side, and the linear driver 122 pushes the hexagonal recess at the end of the driving rod 124 to align and connect with the hexagonal protrusion 1181 at the end of the movable connecting member 118, and then the second motor 123 drives the driving rod 124 to rotate, so that the clamping fingers 112 can complete the actions of closing, clamping and releasing; it should be noted that, since the hexagonal transmission rod 116 is The active worm 114 and the driven worm gear 113 are meshed to close the clamping fingers 112, so the clamping fingers 112 have a self-locking effect. Therefore, the rotating plate 7 rotates ninety degrees with the sample 500 and then returns to a straight state. The movement of the movable frame 3 will not affect the hexagonal transmission rod 116. The sample 500 can still be tightly clamped. Therefore, the hexagonal transmission rod 116 will not rotate without external force. This can ensure that the movable connecting parts 118 can still be aligned and connected at an accurate angle when they are connected to each other next time.

[0054] In a preferred embodiment, Figure 1 , Fig.10 and Fig.11 As shown, in order to facilitate the self-locking clamping jaws 11 to clamp the sample 500 and achieve the effect of automatic material collection and feeding, it also includes: a material collection and feeding mechanism configured on the support leg 101 for orderly providing the sheet-shaped processed materials; the material collection and feeding mechanism specifically includes: a guide frame 131 fixedly installed on the support leg 101, a slit is provided on the guide frame 131 to accommodate the sample 500 to pass through, the sample 500 is placed in the slit and kept in an upright state, a roller bottom plate 132 is fixedly installed at the bottom of the guide frame 131, the roller bottom plate 132 is used to support the bottom of the sample 500 to prevent the sample 500 from falling from the slit of the guide frame 131, and a spacer is provided on the roller bottom plate 132. A transmission roller 1321 is provided to rotate evenly, which is beneficial to the movement of the sample 500. A reduction motor 133 is fixedly installed on the side wall of the supporting foot 101, and a transmission screw 134 is mounted on the guide frame 131. The transmission screw 134 is driven by the reduction motor 133. A moving block 135 is installed on the transmission screw 134. The moving block 135 is translated by the rotation of the transmission screw 134. A suction cup frame 136 is slidably installed on the moving block 135. At the same time, a telescopic push rod 137 is fixedly installed on the moving block 135. The movable rod part of the telescopic push rod 137 passes through the moving block 135 and is connected with the suction cup frame 136, thereby driving the suction cup frame 136 to move.

[0055] according to Fig.10 and Fig.11As shown, after the sample 500 starts to be fed from one side of the guide frame 131, the telescopic push rod 137 drives the suction cup frame 136 to move forward and absorb the sample 500 and then pull it backward, and then the transmission screw 134 drives the moving block 135 to move and evenly spread the sample 500 on the guide frame 131, waiting for the self-locking clamp 11 to take away the sample 500; the feeding and collecting mechanism is arranged on both sides of the support drive frame 1, and the sample 500 starts to be fed from one side of the support drive frame 1. After passing through all the immersion tanks 2, the above-mentioned feeding action is used as the reverse operation to complete the feeding.

[0056] Among them, according to Fig.10 and Fig.11 As shown, in order to ensure that the samples 500 do not contact and collide with each other during the process of collecting and feeding materials, causing wear on the plate surface, the material storage part on the guide frame 131 is further improved. A material storage frame 141 is fixedly installed on the guide frame 131, and a non-powered conveyor belt 143 is installed on the bottom wall and the opposite side walls of the material storage frame 141. The non-powered conveyor belt 143 installed on the opposite side walls on both sides is also evenly spaced with protruding dividing teeth 142. The samples 500 are evenly spaced by the dividing teeth 142 of the non-powered conveyor belt 143 on the side wall. The unpowered conveyor belt 143 allows the sample 500 to slide more smoothly. The unpowered conveyor belt 143 does not require external force to drive it. The surface is covered with a belt that can rotate freely. The sample 500 is placed on the unpowered conveyor belt 143 and can move freely. In the process of taking and releasing materials by the suction cup frame 136, the unpowered conveyor belt 143 with dividing teeth 142 can separate the samples 500, avoiding contact between the samples 500, allowing the samples 500 to collect and supply materials in an orderly manner at intervals. The samples 500 will not contact each other, eliminating the problem of wear on the board surface caused by friction between the samples 500.

[0057] In a preferred embodiment, Figure 1 , Fig.12 and Fig.13As shown, different liquid medicines are used in the process of immersion electroplating of the sample 500. Before electroplating, some of the different liquid medicines need to clean the residual liquid medicines from the previous process. Therefore, a cleaning tank is added in the middle to rinse the residual liquid medicines of the sample 500. In order to enhance the cleaning effect, a cover plate 151 is fixedly installed on these cleaning immersion tanks 2. The cover plate 151 has strip openings evenly spaced at positions corresponding to the rotating plate 7. The clamped sample 500 is immersed in the sample 500 through these strip openings. In the immersion tank 2, a liquid spray rack 152 is symmetrically arranged according to the strip-shaped opening at the bottom of the cover plate 151, and duckbill nozzles 153 are arranged on the liquid spray rack 152. When the sample 500 descends and immerses in the immersion tank 2, the liquid spray rack 152 sprays high-pressure liquid through the duckbill nozzles 153 to spray both sides of the sample 500 for secondary cleaning, and the liquid sprayed by the liquid spray rack 152 can circulate and extract the liquid in the immersion tank 2 to which it is installed for spraying, without the need for an additional external water source for spraying, so as to achieve a water-saving effect.

[0058] Among them, in order to reduce the residual liquid on the sample 500 after spray cleaning, the jet box 161 is symmetrically installed on the top of the cover 151 according to the strip opening. The multiple jet boxes 161 arranged on the cover 151 are supplied with air in series through the same air pipe 162. After the sample 500 is cleaned and in the process of being pulled out, the jet box 161 works to spray the surface of the sample 500 to remove the residual liquid stains on the surface of the sample 500. At the same time, in order to prevent the liquid stains on the surface of the sample 500 from drifting to other areas due to the jet removal, the air outlet blade 1611 in the jet box 161 is arranged at a downward angle of forty-five degrees, so that the gas ejected by the jet box 161 is ejected at a downward angle, which can make the liquid stains on the surface of the sample 500 gather downward and will not drift to other areas.

[0059] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
