Description

TECHNICAL FIELD

[0001] The utility model relates to alkaline zinc nickel barrel plating technical field, concretely to a kind of high-efficiency double-barrel alkaline zinc nickel barrel plating device. BACKGROUND

[0002] Modern high-end manufacturing industry is booming, and the quality requirements of electronic, automobile, aerospace and other fields for parts coating are becoming more stringent. Traditional barrel plating equipment has poor coating uniformity, weak corrosion resistance and low precision, which is difficult to meet the needs of precision parts such as chip pins and aircraft engine blades.

[0003] For example, the zinc-nickel alloy electroplating barrel with the authorization announcement number "CN217351601U" has excellent conductivity and high plating quality. The overall function is perfect and practical. However, the immersion depth of the traditional zinc-nickel barrel plating device is constant, which is difficult to meet the needs of different processes. Processing different sizes and materials of plated parts, uniform immersion depth results in uneven plating. Small parts are easily over-deposited and adhered, and large parts are insufficiently plated and grow slowly. When the contact area with the workpiece is small, the workpiece needs to be rotated multiple times to achieve the desired plating effect, resulting in a decrease in the working efficiency of the zinc-nickel alloy electroplating barrel. At the same time, the barrel of the zinc-nickel alloy electroplating barrel rolls in place, and the plating solution flows in the narrow space inside the barrel. It is easy to form a stagnant zone and a concentration gradient. The plating solution near the barrel wall is slow to update and has a high ion concentration, while the center area is the opposite. This results in large differences in plating thickness and composition at different parts of the plated parts. For plated parts that are not fully plated, secondary barrel plating is required, resulting in a decrease in the working efficiency of the zinc-nickel alloy electroplating barrel. SUMMARY

[0031] Working principle:

[0032] Roll plating operation of alkaline zinc-nickel:

[0033] Movement of the plated part:

[0034] The operator places the plated part in the roller 13 through the box door processed on the outer wall of the roller 13, fixes the box door through the bolt, connects the external power supply of the second motor 501, starts the second motor 501, the output shaft of the second motor 501 drives the worm 502 to rotate (as shown in Figure 6), the worm 502 rotates to drive the worm wheel 503 to rotate, the worm wheel 503 rotates to drive the cylinder 504 to rotate, and the cylinder 504 rotates while sliding left and right in the groove frame 505. Since the groove frame 505 makes the cylinder 504 slide left and right, the cylinder 504 makes the groove frame 505 slide up and down on the second slide rod 506. The groove frame 505 moves to drive the vertical rod 507 to move, and the vertical rod 507 moves to drive the two rollers 13 to move into the plating solution pool 15. The plating solution pool 15 has plating solution inside. The plating solution is an alkaline zinc-nickel solution, which is a metal ion source, provides nickel ions, etc. in the plating of nickel, and deposits a plating layer on the surface of the plated part under the driving of an electric field. When the rollers 13 are moved to the appropriate depth, the second motor 501 is turned off.

[0035] Roll plating of alkaline zinc-nickel:

[0036] The external power supply of the third motor 8 is turned on, and the third motor 8 is started. The output shaft of the third motor 8 rotates to drive the first bevel gear 9 to rotate (as shown in Figure 2 ), the first bevel gear 9 rotates to drive the second bevel gear 11 to rotate, the second bevel gear 11 rotates to drive the round rod 12 to rotate, and the round rod 12 rotates to drive the rollers 13 to roll in the plating solution pool 15. When the rollers 13 rotate, the plated part continuously rolls and changes position, and each surface periodically contacts the plating solution and the anode. Under the action of an electric field, metal ions in the plating solution migrate directionally, and are reduced to metal atoms on the surface of the plated part to deposit a plating layer, thereby achieving the purpose of roll plating of alkaline zinc-nickel. However, the flow of the plating solution is limited to the narrow space inside the rollers, and stagnant flow areas and concentration gradients are easily formed. At this time, the external power supply of the first motor 401 is turned on, and the first motor 401 is started. The output shaft of the first motor 401 rotates to drive the disc 402 to rotate (as shown in Figure 5 ), the disc 402 rotates to drive the cam 403 to rotate around the pin shaft connecting the disc 402 and the cam 403, and the other end of the cam 403 rotates around the pin shaft connecting the cam 403 and the slider 404 on the slider 404, thereby making the slider 404 slide on the first slide rod 405. The slider 404 moves to drive the top plate 406 to move, and the top plate 406 moves to drive the second housing 14 to press the bottom forward, thereby driving the plated part to move forward. When the disc 402 rotates 180 degrees, the disc 402 moves the plated part backward by the above-mentioned method, thereby making the plated part move back and forth in the plating solution pool 15 while continuously rolling and changing position. This can strongly break the concentration gradient, and the reciprocating movement structure can disturb the flow of the plating solution to provide a stable ion environment for the growth of the plating layer. After the roll plating is completed, the first motor 401 and the third motor 8 are turned off.

[0037] Taking out the plated part:

[0038] Start the second motor 501, the output shaft of the second motor 501 rotates in the direction opposite to the above-mentioned movement direction, the second motor 501 makes the plated piece ascend through the above-mentioned connection mode, close the second motor 501, the box door processed by the roller 13 takes out the plated piece, and the box door is fixed on the roller 13 again through the bolt, namely, the processing flow of the high-efficiency double-barrel alkaline zinc-nickel barrel plating device is completed.
