Description

Technical Field

[0002] Acid copper plating has high current efficiency and simple composition. After adding brightener, a fully bright and tough coating can be obtained. It is currently the most superior plating type in leveling and brightness.

[0003] The invention patent with the authorization announcement number CN103320820B discloses an acid bright copper plating process, including the steps of preparing a copper plating solution, pretreatment of a workpiece, and acid bright copper plating. The process of the present invention can continuously plate a copper plating layer several millimeters thick on the surface of a metal substrate without the need for multiple electroplatings; the electroplated cast copper has good bonding strength with the substrate and can withstand machining forces such as turning, milling, stretching, and polishing; the plating solution has good stability and a uniform surface.

[0004] When preparing the copper plating solution in the above electroplating process, it is necessary to complete the mixing of deionized water, sulfuric acid and copper sulfate in a pre-tank, then evenly sprinkle activated carbon into the mixed solution, wait for the solution in the pre-tank to clarify, then filter, and transfer the filtrate into the electroplating tank.

[0005] However, technicians in this field have found in actual applications that in order to ensure that the activated carbon can be evenly spread, this operation is often performed manually, which wastes manpower. The activated carbon will also be scattered during the sprinkling process, which not only wastes raw materials but also affects the working environment. In addition, since the amount of solution to be filtered in the pre-use tank is large, the traditional filtration method will consume a long time, which has a great impact on the efficiency of electroplating solution preparation.

[0006] Therefore, a high-efficiency acid bright copper plating automatic electroplating equipment is invented to realize a one-stop acid bright copper plating process. Summary of the invention

[0021] The device principle includes the following:

[0022] Deionized water is added into the pre-mixing tank, the driving motor (63) drives the hollow shaft (62) to rotate via the driving gear (64), the hollow shaft (62) drives the trigger plate (71) to rise when rotating, the trigger plate (71) drives the screw (81) to rotate when rising, the screw (81) drives a plurality of second stirring rods (86) to stir the deionized water, sulfuric acid and copper sulfate are added in sequence, the sulfuric acid and deionized water are uniformly mixed to form a mixed solution under the continuous stirring of the second stirring rods (86), and the copper sulfate is dissolved in the mixed solution;

[0023] When the trigger plate (71) rises, it drives the compressed first spring (72) to gradually reset. At this time, the activated carbon powder is added into the activated carbon powder feeding tank (3). The activated carbon powder continuously falls from the discharge port at the bottom of the activated carbon powder feeding tank (3) onto the top of the throwing plate (65). The continuously rotating throwing plate (65) evenly throws the activated carbon powder falling on the top thereof, and the activated carbon powder evenly falls into the mixed solution.

[0024] The plurality of second stirring rods (86) continue to stir the mixed solution, and when the rising distance of the trigger plate (71) reaches a first threshold, the drive motor (63) is stopped to wait for the mixed solution to be clarified, and then the drive motor (63) is started again. At this time, as the trigger plate (71) continues to rise, the trigger plate (71) pulls the upper closing plate (73) through the first spring (72);

[0025] When the trigger plate (71) rises to a second threshold, the upper sealing plate (73) releases the blockage on the partition plate (4), and at the same time, the T-shaped blocking rod (97) rises under the push of the trigger plate (71), thereby releasing the blockage on the second valve (96) from the inside of the hollow shaft (62), and the clarified mixed solution passes through the channel on the partition plate (4) and falls onto the top of the filter plate (5) to be filtered by the filter plate (5);

[0027] When the trigger plate (71) rises to a third threshold, the mixed solution on the top of the partition plate (4) passes through the channel on the partition plate (4) and falls onto the top of the filter plate (5). The lower closing plate (75) is also driven by the connecting rod (74) to block the channel on the partition plate (4) from below, and then the drive motor (63) is shut down. At this time, the brightener continuously passes through the second valve (96) into the chamber formed between the partition plate (4) and the filter plate (5). Since the partition plate (4) is closed, when the pressure between the partition plate (4) and the filter plate (5) increases, the mixed solution passes through the filter plate (5) faster due to the pressure and falls into the electroplating tank (2) until the copper plating solution is transferred.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] Provided is an acid bright copper electroplating device to achieve efficient acid bright copper automatic electroplating. The device is provided with a driving mechanism, a trigger-type blocking mechanism, an adjustable stirring mechanism and a trigger-type mixing and feeding mechanism, so that the driving mechanism can drive the adjustable stirring mechanism to achieve material mixing while driving the trigger-type blocking mechanism, thereby causing the trigger-type blocking mechanism to release the blocking of the partition plate and achieve rapid output of the mixed solution. In addition, the trigger-type blocking mechanism can trigger the trigger-type mixing and feeding mechanism while releasing the blocking of the partition plate, thereby causing the trigger-type mixing and feeding mechanism to continuously input brightener and mix with the mixed solution. In addition, when the trigger-type blocking mechanism blocks the partition plate again, the trigger-type mixing and feeding mechanism can increase the pressure between the partition plate and the filter plate, thereby accelerating the speed at which the solution is filtered. Compared with the same type of method in the prior art, the present invention saves manpower and has a higher degree of automation. In addition, it can effectively reduce the drift generated during the addition of activated carbon, and at the same time, it can complete the transfer of the electroplating solution faster, thereby improving the efficiency of preparing the electroplating solution.

[0041] By setting the above structure, after the driving motor 63 is started, the driving gear 64 drives the hollow shaft 62 to rotate, and the hollow shaft 62 continuously drives the spreading plate 65 to rotate. After the activated carbon powder continuously falls on the top of the spreading plate 65 from the discharge port at the bottom of the activated carbon powder feeding tank 3, the continuously rotating spreading plate 65 will evenly throw the activated carbon powder falling on the top thereof, and the activated carbon powder evenly falls into the mixed solution.

[0043] By setting the above structure, when the trigger plate 71 rises, the compressed first spring 72 is gradually reset. When the rising distance of the trigger plate 71 reaches the second threshold, the upper closing plate 73 releases the blockage of the partition plate 4. At this time, the clarified mixed solution passes through the channel on the partition plate 4 and falls into the top of the filter plate 5 to be filtered by the filter plate 5.

[0044] like Figure 4 As shown, the adjustable stirring mechanism 8 includes a screw 81, a first stirring rod 82, a longitudinal slide groove 83, a sliding column 84, a sliding sleeve 85, a second stirring rod 86 and a second spring 87, wherein the screw 81 passes through the partition plate 4 and is rotatably connected to the partition plate 4 through a bearing, the screw 81 passes through the trigger plate 71 and is threadedly connected to the trigger plate 71, and the first stirring rod 82, the sliding column 84, the sliding sleeve 85, the second stirring rod 86 and the second spring 87 are all provided in plurality, and the plurality of first stirring rods 82 are uniformly fixed The plurality of sliding sleeves 85 are slidingly sleeved on the outside of the screw 81 and are respectively fixedly connected to the plurality of sliding columns 84.

The plurality of second springs 87 are evenly sleeved on the outside of the screw 81. Any second spring 87 is located between two adjacent sliding sleeves 85.

[0045] By setting the above structure, when the trigger plate 71 rises, the screw 81 is driven to rotate, and the screw 81 drives multiple second stirring rods 86 to stir the material, thereby making the material evenly mixed or accelerating the dissolution. At the same time, when the trigger plate 71 rises, the compressed second spring 87 can push the sliding sleeve 85, thereby making the sliding sleeve 85 drive the second stirring rod 86 to rise, thereby adjusting the stirring height. At the same time, the screw 81 can also stir and mix the mixed solution to be filtered and the brightener through the first stirring rod 82.

[0046] like Figure 3 and Figure 5 As shown, the trigger-type mixing and feeding mechanism 9 includes a brightener storage tank 91, a first valve 92, an air inlet pipe 93, an air pump 94, a discharge pipe 95, a second valve 96, a T-shaped blocking rod 97 and a third spring 98, wherein the brightener storage tank 91 is fixedly arranged on the right side of the pre-mixing tank 1, the first valve 92 is fixedly nested and arranged on the top of the right side of the brightener storage tank 91, the air inlet pipe 93 is fixedly penetrated and arranged on the right side of the brightener storage tank 91 and is connected to the output end of the air pump 94, the discharge pipe 95 is fixedly penetrated and arranged on the bottom of the brightener storage tank 91 and is connected to the bottom end of the hollow shaft 62 through a rotating joint, a plurality of second valves 96 are provided, and a plurality of second valves 96 are evenly fixedly nested and arranged on the outer bottom of the hollow shaft 62, the T-shaped blocking rod 97 is slidably nested and arranged on the inner side of the hollow shaft 62 along the vertical direction, and one end of the third spring 98 is fixedly connected to the inner wall of the hollow shaft 62 and the other end is fixedly connected to the T-shaped blocking rod 97.

At this time, the clarified mixed solution passes through the channel on the partition plate 4 and falls into the top of the filter plate 5 to be filtered by the filter plate 5. At the same time, after the second valve 96 is unblocked, the air pump 94 inputs the airflow into the brightener storage tank 91 through the air inlet pipe 93 to push the brightener in the brightener storage tank 91. The brightener enters the hollow shaft 62 through the discharge pipe 95, and then is sprayed out through multiple second valves 96, and then mixed with the mixed solution to be filtered to form a copper plating solution.

[0048] In addition, when the channel on the partition plate 4 is blocked again, the brightener continues to pass through the second valve 96 into the chamber formed between the partition plate 4 and the filter plate 5.

At this time, the activated carbon powder is added into the activated carbon powder feeding tank 3, and the activated carbon powder continuously falls on the top of the throwing plate 65 from the discharge port at the bottom of the activated carbon powder feeding tank 3. The continuously rotating throwing plate 65 evenly throws the activated carbon powder falling on the top thereof, and the activated carbon powder evenly falls into the mixed solution;

[0053] S3, the plurality of second stirring rods 86 continue to stir the mixed solution, and when the rising distance of the trigger plate 71 reaches the first threshold, the drive motor 63 is stopped to wait for the mixed solution to be clarified, and then the drive motor 63 is started again. At this time, as the trigger plate 71 continues to rise, the trigger plate 71 pulls the upper closing plate 73 through the first spring 72;

[0054] S4, when the trigger plate 71 rises to a second threshold, the upper sealing plate 73 releases the blockage of the partition plate 4, and at the same time, the T-shaped blocking rod 97 rises under the push of the trigger plate 71, and then the blockage of the second valve 96 is released from the inside of the hollow shaft 62, and the clarified mixed solution passes through the channel on the partition plate 4 and falls into the top of the filter plate 5 to be filtered by the filter plate 5;

[0056] S6, when the trigger plate 71 rises to a third threshold, the mixed solution on the top of the partition plate 4 passes through the channel on the partition plate 4 and falls into the top of the filter plate 5, and the lower closing plate 75 blocks the channel on the partition plate 4 from below under the drive of the connecting rod 74, and then the driving motor 63 is stopped. At this time, the brightener continuously passes through the second valve 96 into the chamber formed between the partition plate 4 and the filter plate 5. Since the partition plate 4 is closed, when the pressure between the partition plate 4 and the filter plate 5 is increased, the mixed solution passes through the filter plate 5 faster due to the pressure and falls into the electroplating tank 2 until the copper plating solution is transferred.

7. The acid bright copper plating device according to claim 6, characterized in that: The driving motor (63) drives the hollow shaft (62) to rotate via the driving gear (64). When the hollow shaft (62) rotates, the trigger plate (71) is driven to rise. When the trigger plate (71) rises, the screw (81) is driven to rotate. The screw (81) drives a plurality of second stirring rods (86) to stir the deionized water. Sulfuric acid and copper sulfate are added in sequence. Under the continuous stirring of the second stirring rods (86), the sulfuric acid and the deionized water are uniformly mixed to form a mixed solution, and the copper sulfate is dissolved in the mixed solution.

8. The acid bright copper plating device according to claim 7, characterized in that: When the trigger plate (71) rises, it drives the compressed first spring (72) to gradually reset. At this time, the activated carbon powder is added into the activated carbon powder feeding tank (3). The activated carbon powder continuously falls from the discharge port at the bottom of the activated carbon powder feeding tank (3) onto the top of the throwing plate (65). The continuously rotating throwing plate (65) evenly throws the activated carbon powder falling on the top thereof, and the activated carbon powder evenly falls into the mixed solution. The plurality of second stirring rods (86) continue to stir the mixed solution. When the rising distance of the trigger plate (71) reaches a first threshold, the drive motor (63) is stopped to wait for the mixed solution to be clarified. The drive motor (63) is then started again. At this time, as the trigger plate (71) continues to rise, the trigger plate (71) pulls the upper closing plate (73) through the first spring (72).

9. The acid bright copper plating device according to claim 8, characterized in that: When the trigger plate (71) rises to a second threshold, the upper sealing plate (73) releases the blockage on the partition plate (4), and at the same time, the T-shaped blocking rod (97) rises under the push of the trigger plate (71), thereby releasing the blockage on the second valve (96) from the inside of the hollow shaft (62), and the clarified mixed solution passes through the channel on the partition plate (4) and falls onto the top of the filter plate (5) to be filtered by the filter plate (5); After the second valve (96) is unblocked, the air pump (94) inputs the airflow into the brightener storage tank (91) through the air inlet pipe (93) to push the brightener in the brightener storage tank (91), and the brightener enters the hollow shaft (62) through the discharge pipe (95), and then is sprayed out through the plurality of second valves (96), and then mixed with the mixed solution to be filtered to form a copper plating solution.

10. The acid bright copper plating device according to claim 9, characterized in that: When the trigger plate (71) rises to a third threshold, the mixed solution on the top of the partition plate (4) passes through the channel on the partition plate (4) and falls onto the top of the filter plate (5). The lower closing plate (75) is also driven by the connecting rod (74) to block the channel on the partition plate (4) from below, and then the drive motor (63) is shut down. At this time, the brightener continuously passes through the second valve (96) into the chamber formed between the partition plate (4) and the filter plate (5). Since the partition plate (4) is closed, when the pressure between the partition plate (4) and the filter plate (5) increases, the mixed solution passes through the filter plate (5) faster due to the pressure and falls into the electroplating tank (2) until the copper plating solution is transferred.
