Description

Technical Field

[0001] The present invention relates to the technical field of electroplating, and more specifically, to an electroplating device for passive aluminum alloy profiles. Background Art

[0002] The purpose of electroplating aluminum alloy profiles is to comprehensively improve their performance and value. By forming a metal coating on the surface, it can not only enhance the corrosion resistance and wear resistance in different environments and extend the service life, but also provide diversified choices in decoration to meet the aesthetic needs of different scenes. At the same time, it gives it special functionality, expands the application field, and to a certain extent improves the processing performance, improves production efficiency and product quality, making aluminum alloy profiles more competitive and applicable in many fields.

[0003] In the past, when electroplating aluminum alloy profiles, it was necessary to use a clamp to hang or clamp the aluminum. The contact part or the position blocked by the clamp had a poor electroplating effect in the electroplating tank, and this position required good electroplating. The workers would then replace the clamp and perform a second electroplating on the contact part of the workpiece. The electroplating efficiency was low. Although this method electroplated the contact part of the workpiece, the plating thickness and the electroplating reaction time usually had a positive correlation. When other conditions remained unchanged, the plating time would generally increase the plating thickness. During the electroplating process, the workpiece was electroplated twice at the position that was not in contact with the clamp, and its plating thickness was greater than the plating thickness of the two contact parts between the clamp and the workpiece. The plating thickness was uneven, resulting in poor electroplating effect. In view of this, we propose a passive electroplating equipment for aluminum alloy profiles. Summary of the invention

[0015] The beneficial effects of the present invention are: 1. The present invention designs a structural design structure of a fixing mechanism, so that when the outer surface of the aluminum alloy profile is electroplated, the inner surface of the aluminum alloy profile is tensioned and fixed in a covering manner by a tensioning component, and when the inner surface of the aluminum alloy profile is electroplated, the inner surface of the aluminum alloy profile is clamped and fixed in a covering manner by a clamping component, thereby saving electroplating solution, and the outer surface of the aluminum alloy profile only needs to be electroplated once. When it is necessary to electroplate the inner and outer surfaces of the aluminum alloy profile, electroplating can be performed twice in the same steps as above, thereby solving the technical problem of uneven electroplating of the aluminum alloy profile.

[0016] 2. The present invention adopts the structural setting of the displacement guide groove A, so that when two of the movable columns A are respectively located at the eccentric ends of the two positive inclined grooves A, the other two movable columns A are respectively located at one end of the two centripetal arc grooves A, and the adjusting ring plate is rotated. When the two movable columns A are respectively moved to the centripetal ends of the two positive inclined grooves A, the corresponding centripetal sliders slide to the centripetal ends of the centripetal slide grooves, so that the corresponding two clamping blocks clamp the surface of the aluminum alloy profile, and the other two movable columns A are respectively moved to the other ends of the two centripetal arc grooves A, and the corresponding two clamping blocks maintain a clamping state on the surface of the aluminum alloy profile, wherein the two movable columns A are respectively moved from the centripetal ends of the two positive inclined grooves A to one end of the two centripetal arc grooves B, and the other two movable columns A are moved from the two centripetal ends of the two positive inclined grooves A to one end of the two centripetal arc grooves B. The other end of each centripetal arc groove A is movable to the eccentric end of the anti-inclined groove A, so that the four clamping blocks can be staggered in pairs. Under the premise of ensuring uniform electroplating, the electroplating of the outer surface of the aluminum alloy profile can be divided into two times, which is convenient for different electroplating requirements at different positions on the surface of the aluminum alloy profile. For example, decorative aluminum alloy profiles need to perform striped two-color electroplating on the outer surface. The unclamped part of the aluminum alloy profile can be electroplated first, and then the aluminum alloy profile can be transferred to another electroplating tank. Through the above operation, the other two clamping blocks can clamp, fix and shield the electroplated position, and use the electroplating solution in another electroplating tank to electroplate the unplated position. The fixing method of electroplating can be selected according to actual electroplating requirements.

[0017] 3. The present invention sets the centripetal arc groove A, the positive inclined groove A, the reverse inclined groove A, the centripetal arc groove B, the eccentric arc groove B and the positive inclined groove B with equal active angles, so that under the premise of electroplating the inner and outer surfaces of the aluminum alloy profile and dividing the electroplating of the outer surface of the aluminum alloy profile into two times, when two of the movable columns A are respectively located at the eccentric ends of the two positive inclined grooves A, the other two movable columns A are respectively located at one end of the two centripetal arc grooves A, and the movable column B is located at the end of the eccentric arc groove B away from the positive inclined groove B, the tensioning assembly performs covering tensioning and fixing on the inner surface of the aluminum alloy profile, wherein the two clamping blocks clamp the outer surface of the aluminum alloy profile, and at this time, part of the outer surface of the aluminum alloy profile can be electroplated. After the electroplating is completed, the adjusting circular plate and the adjusting ring plate are rotated at the same time. When the two movable columns A are respectively moved from the two centripetal arc grooves A at one end to the two centripetal arc grooves A at the other end, When the adjusting plate and the adjusting ring plate are rotated, the movable column B moves from one end of the eccentric arc slot B to the other end of the eccentric arc slot B. At this time, the four clamping blocks cover and clamp the outer surface of the aluminum alloy profile, and the tensioning assembly covers and tensions the inner surface of the aluminum alloy profile. Continue to rotate the adjusting circular plate and the adjusting ring plate to make the movable column B move to the centripetal end of the positive inclined slot B, and the tensioning block is separated from the inner surface of the aluminum alloy profile. At the same time, two of the movable columns A move from the centripetal ends of the two positive inclined slots A to one end of the two centripetal arc slots B respectively, and the other two movable columns A move from the other ends of the two centripetal arc slots A to the eccentric ends of the reverse inclined slot A respectively, so that the two clamping blocks are separated from the outer surface of the aluminum alloy profile, and the other two clamping blocks cover and clamp the electroplated position of the outer surface of the aluminum alloy profile, move the aluminum alloy profile to another electroplating tank, and electroplate the unplated part of the aluminum alloy profile.

[0018] 4. The present invention adopts the structural design of the reverse rotating component and the forward rotating component, so that when the adjusting circular plate rotates forward, under the friction force of the inner edge surface of the adjusting ring plate, the movable column A has the force to move toward the reverse triangular groove, so that the adjusting circular plate cannot rotate clockwise relative to the adjusting ring plate. Similarly, it can be known that the adjusting ring plate cannot rotate counterclockwise. Therefore, when the adjusting circular plate rotates clockwise, it drives the adjusting ring plate to rotate clockwise. When the adjusting circular plate rotates counterclockwise, the adjusting ring plate does not rotate, and in the static state, the adjusting ring plate cannot rotate clockwise relative to the adjusting circular plate. Therefore, the adjusting ring plate is in a state of being unable to rotate, so that the clamping state of the clamping assembly is stable after adjustment.

[0019] 5. The present invention uses the structural design of the placement mechanism to place multiple aluminum alloy profiles to be electroplated on the placement column. The chamfer on the top of the positioning column facilitates the placement of the aluminum alloy profile to be electroplated. The positioning column positions the aluminum alloy profile to be electroplated. When the fixing mechanism fixes the aluminum alloy profile, the fixing mechanism descends, and the bottom end of the tensioning assembly contacts the top end of the positioning column, so that the positioning column slides down along the slide hole, and the limit slider slides relative to the limit slide groove until the aluminum alloy profile to be electroplated enters the gap between the clamping assembly and the tensioning assembly, which is convenient for the fixation of the fixing mechanism.

The eight movable columns B531 are all movably connected to the displacement guide grooves B535. Through the structural design of the tensioning assembly 53, the present invention enables the rotating adjustment circular plate 534 and the eight displacement guide grooves B535 to enable the eight movable columns B531 to respectively drive the eight tensioning blocks 533 to perform centripetal movement, and the gear A532 moves relative to the tooth groove 513 so that the gear A532 drives the movable column B531 and the adjustment ring plate 524 to rotate.

After the electroplating is completed, the adjusting circular plate 534 and the adjusting ring plate 524 are rotated at the same time, and when the two movable columns A523 move from the two ends of the centripetal arc grooves A5251 to the two centripetal arc grooves A5352, respectively. 251, the movable column B531 moves from one end of the eccentric arc groove B5351 to the other end of the eccentric arc groove B5351. At this time, the four clamping blocks 522 cover the outer surface of the aluminum alloy profile, and the tensioning assembly 53 covers and tightens the inner surface of the aluminum alloy profile. The adjusting circular plate 534 and the adjusting ring plate 524 are continuously rotated to make the movable column B531 move to the centripetal end of the positive inclined groove B5352, and the tensioning block 533 is separated from the inner surface of the aluminum alloy profile. At the same time, two of the movable The movable column A523 moves from the centripetal ends of the two positive inclined grooves A5252 to one end of the two centripetal arc grooves B5254 respectively, and the other two movable columns A523 move from the other ends of the two centripetal arc grooves A5251 to the eccentric ends of the reverse inclined grooves A5253 respectively, so that the two clamping blocks 522 are separated from the outer surface of the aluminum alloy profile, and the other two clamping blocks 522 cover and clamp the electroplated positions on the outer surface of the aluminum alloy profile, and the aluminum alloy profile is moved to another electroplating tank to electroplate the unplated parts of the aluminum alloy profile.

[0029] In the embodiment of the present invention, the reverse rotation component 54 includes a plurality of reverse triangular grooves 541 in an annular equidistant structure and arranged on the outer edge of the adjusting circular plate 534. The depth of the reverse triangular grooves 541 gradually decreases in the counterclockwise direction. The reverse triangular grooves 541 and the inner edge of the adjusting ring plate 524 form a forward limiting cavity. A limiting column A542 is movably arranged in the forward limiting cavity. The limiting column A542 is elastically connected to the deep part of the reverse triangular groove 541 through a spring A543. The forward rotating component 55 includes an equilateral triangular groove 551 in a ring-shaped and equidistantly spaced structure opened on the outer edge surface of the adjusting ring plate 524. The groove depth of the equilateral triangular groove 551 gradually decreases in the clockwise direction. The equilateral triangular groove 551 and the inner edge surface of the rotating groove 41 constitute a reverse limit cavity. A limit column B552 is movably provided in the reverse limit cavity. The limit column B552 is elastically connected to the deep part of the reverse limit cavity by a spring B553. The present invention adopts the structural design of the reverse rotating component 54 and the forward rotating component 55, so that when the adjusting circular plate 534 rotates forward, under the friction force of the inner edge surface of the adjusting ring plate 524, the movable column A523 has the force to move toward the reverse triangular groove 541, so that the adjusting circular plate 534 cannot rotate clockwise relative to the adjusting ring plate 524. Similarly, it can be known that the adjusting ring plate 524 cannot rotate counterclockwise. Therefore, when the adjusting circular plate 534 rotates clockwise, it drives the adjusting ring plate 524 to rotate clockwise. When the adjusting circular plate 534 rotates counterclockwise, the adjusting ring plate 524 does not rotate, and in the static state, the adjusting ring plate 524 cannot rotate clockwise relative to the adjusting circular plate 534. Therefore, the adjusting ring plate 524 is in a state of being unable to rotate, so that the clamping state of the clamping component 52 is stable after adjustment.

The plurality of gears C63 are respectively disposed on the tops of the plurality of rotating grooves 41. The plurality of gears C63 are all meshedly connected to the gear B62. A connecting shaft 65 is fixedly mounted on the bottom end of the gear C63. The bottom end of the connecting shaft 65 is fixedly connected to the top of the adjusting circular plate 534. The present invention uses the structural design of the rotating mechanism 6 so that the output shaft of the motor 61 is controlled to rotate by an external control mechanism, so that the rotating shaft 64 drives the gear B62 to rotate, and the plurality of gears C63 rotate, so that the plurality of connecting shafts 65 simultaneously drives the plurality of adjusting circular plates 534 to rotate.
