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] Electroplating of 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, extend the service life, but also provide diverse choices in decoration to meet the aesthetic needs of different scenarios. At the same time, it endows special functionality, expands the application fields, and to a certain extent improves the processing performance, production efficiency and product quality, making the aluminum alloy profiles more competitive and applicable in many fields.

[0003] In the past, when electroplating aluminum alloy profiles, fixtures were required to suspend or clamp the aluminum materials. However, the electroplating effect at the contact parts or the clamped and blocked positions in the electroplating tank was poor, and good electroplating was required at these positions. Workers would then replace the contact parts of the fixtures and the workpieces for secondary electroplating, resulting in low electroplating efficiency. Moreover, although this method electroplates the contact parts of the workpieces, there is usually a positive correlation between the coating thickness and the electroplating reaction time. When other conditions remain unchanged, an extended electroplating time generally increases the coating thickness. During the electroplating process, the positions of the workpieces that are not in contact with the fixtures are electroplated twice, and their coating thickness is greater than that of the two contact parts between the fixtures and the workpieces, resulting in uneven coating thickness and poor electroplating effect. In view of this, we propose an electroplating device for passive aluminum alloy profiles. Summary of the Invention

The limiting slider is fixedly connected to the top end of the sliding hole.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. Through the structural design of the fixing mechanism of the present invention, when electroplating the outer surface of the aluminum alloy profile, the inner surface of the aluminum alloy profile is covered and tension-fixed by the tensioning assembly. When electroplating the inner surface of the aluminum alloy profile, the inner surface of the aluminum alloy profile is covered and clamped by the clamping assembly, saving electroplating solution. The outer surface of the aluminum alloy profile can be electroplated once. When it is necessary to electroplate the inner and outer surfaces of the aluminum alloy profile, electroplating can be carried out twice according to the above steps, solving the technical problem of uneven electroplating of aluminum alloy profiles.

[0020] 2. Through the structural arrangement of the displacement guide groove A, 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. Rotate the adjusting ring plate. When two of the movable columns A respectively move to the centripetal ends of the two positive inclined grooves A, the corresponding centripetal sliders slide to the centripetal ends of the centripetal sliding grooves, so that the corresponding two clamping blocks clamp the surface of the aluminum alloy profile. The other two movable columns A respectively move to the other ends of the two centripetal arc grooves A, and the corresponding two clamping blocks keep clamping the surface of the aluminum alloy profile. When two of the movable columns A respectively move 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 respectively move from the other ends of the two centripetal arc grooves A to the eccentric ends of the reverse inclined groove A, the four clamping blocks can clamp in a pairwise staggered manner, so that on the premise of ensuring uniform electroplating, the electroplating of the outer surface of the aluminum alloy profile can be divided into two times, facilitating different electroplating requirements for different positions on the surface of the aluminum alloy profile. For example, for a decorative aluminum alloy profile that needs to be electroplated with striped double colors on the outer surface, the unclamped part of the aluminum alloy profile can be electroplated first, and then the aluminum alloy profile is transferred to another electroplating tank. Through the above operations, the other two clamping blocks clamp and block the electroplated position, and the unplated position is electroplated with the electroplating solution in the other electroplating tank. The electroplating fixing method can be selected according to actual electroplating requirements.

[0021] 3. By setting the equal moving angles of 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, when 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 posts A are respectively located at the eccentric ends of the two positive inclined grooves A, the other two movable posts A are respectively located at one ends of the two centripetal arc grooves A, and the movable post B is located at the end of the eccentric arc groove B far from the positive inclined groove B, the tensioning assembly covers and tension-fixes the inner surface of the aluminum alloy profile, and two of the clamping blocks clamp the outer surface of the aluminum alloy profile. At this time, a 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 simultaneously. When the two movable posts A move from one ends of the two centripetal arc grooves A to the other ends of the two centripetal arc grooves A respectively, the movable post B moves from one end of the eccentric arc groove B to the other end of the eccentric arc groove 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 tension-fixes the inner surface of the aluminum alloy profile. Continue to rotate the adjusting circular plate and the adjusting ring plate so that the movable post B moves to the centripetal end of the positive inclined groove B, and the tensioning block disengages from the inner surface of the aluminum alloy profile. At the same time, two of the movable posts A move from the centripetal ends of the two positive inclined grooves A to one ends of the two centripetal arc grooves B respectively, and the other two movable posts A move from the other ends of the two centripetal arc grooves A to the eccentric ends of the reverse inclined grooves A respectively, so that the two clamping blocks disengage 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. The aluminum alloy profile is moved to another electroplating tank to electroplate the unplated part of the aluminum alloy profile.

[0022] 4. Through the structural design of the reverse rotation assembly and the forward rotation assembly of the present invention, when the adjusting circular plate rotates forward, under the friction force of the inner edge surface of the adjusting ring plate, the movable post A has a force to move towards 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 non-rotatable state, making the clamping state of the clamping assembly stable after adjustment.

[0023] 5. Through the structural design of the placement mechanism of the present invention, multiple aluminum alloy profiles to be electroplated can be placed on the placement posts. The chamfer at the top of the positioning post facilitates the placement of the aluminum alloy profile to be electroplated. The positioning post 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 post, so that the positioning post slides down along the sliding hole, and the limit slider slides relative to the limit sliding groove until the aluminum alloy profile to be electroplated enters the gap between the clamping assembly and the tensioning assembly, facilitating the fixing of the fixing mechanism.

[0052] As Figures 1 to 15 shown, a passive electroplating device for aluminum alloy profiles of the present invention includes an electroplating tank system 1. A moving mechanism 2 is installed at the top of the electroplating tank system 1. A lifting mechanism 3 is installed at the movable end of the moving mechanism 2. A mounting plate 4 is fixedly provided at the movable end of the lifting mechanism 3. A plurality of rotating tanks 41 are arranged in an annular equidistant structure at the bottom of the mounting plate 4 corresponding to the positions of a plurality of cavities of the electroplating tank system 1. A fixing mechanism 5 is provided on the rotating tank 41. A rotating mechanism 6 for synchronously adjusting a plurality of fixing mechanisms 5 is provided on the mounting plate 4. A plurality of placing mechanisms 7 are fixedly provided on one side of the electroplating tank system 1 corresponding to the positions of a plurality of fixing mechanisms 5;

[0053] The fixing mechanism 5 includes a fixing circular plate 51, the fixing circular plate 51 is fixedly arranged at the bottom end of the rotating groove 41, a clamping assembly 52 is arranged on one eccentric side of the fixing circular plate 51, a tensioning assembly 53 is arranged on one centripetal side of the fixing circular plate 51. Both the clamping assembly 52 and the tensioning assembly 53 are of a covering structure. The adjusting end of the clamping assembly 52 is connected to the adjusting end of the tensioning assembly 53 through a reverse rotation assembly 54, and the clamping assembly 52 is connected to the rotating groove 41 through a forward rotation assembly 55.

[0054] In an embodiment of the present invention, a circular cavity 42 is formed in the mounting plate 4, and the tops of a plurality of rotating grooves 41 are all communicated with the circular cavity 42.

[0055] In an embodiment of the present invention, four centripetal sliding grooves 511 are arranged in an annular and equally spaced structure on one eccentric side of the fixing circular plate 51, eight centripetal guide grooves 512 are arranged in an annular and equally spaced structure on one centripetal side of the fixing circular plate 51, and a tooth groove 513 is arranged at the bottom end of the centripetal guide groove 512.

[0056] In an embodiment of the present invention, the clamping assembly 52 includes an adjusting ring plate 524 and four centripetal sliding blocks 521. The centripetal sliding blocks 521 are slidably arranged on the centripetal sliding grooves 511. A clamping block 522 is fixedly arranged at the bottom end of the centripetal sliding block 521. The four clamping blocks 522 can enclose a covering clamping cavity. A movable column A523 is rotatably connected to the top end of the centripetal sliding block 521. The adjusting ring plate 524 is arranged above the fixing circular plate 51. A displacement guide groove A525 is formed at the bottom end of the adjusting ring plate 524. The four movable columns A523 are all movably connected to the displacement guide groove A525 so that the four clamping blocks 522 can be clamped alternately in pairs. Through the above settings of the present invention, when the adjusting ring plate 524 is rotated, the displacement guide groove A525 rotates, and the four movable columns A523 all move in the displacement guide groove A525, so that the four centripetal sliding blocks 521 slide on the four centripetal sliding grooves 511 respectively to drive the four clamping blocks 522 to be clamped alternately in pairs.

[0057] In an embodiment of the present invention, the displacement guide groove A525 includes two centripetal arc grooves A5251 arranged in an axially symmetric structure and two positive inclined grooves A5252 arranged in a radially symmetric structure. An anti-inclined groove A5253 is communicated with one end of the centripetal arc groove A5251. A centripetal arc groove B5254 is arranged at one end of the positive inclined groove A5252. The centripetal arc groove A5251 is communicated with the centripetal arc groove B5254 through a V-shaped groove 5255. The positive inclined groove A5252 is communicated with the anti-inclined groove A5253 through an eccentric arc groove A5256. Through the structural setting of the displacement guide groove A525 in the present invention, as Figure 10As shown, when two of the movable posts A523 are respectively located at the eccentric ends of the two positive inclined grooves A5252, the other two movable posts A523 are respectively located at one end of the two centripetal arc grooves A5251. Rotate the adjusting ring plate 524. When two of the movable posts A523 respectively move to the centripetal ends of the two positive inclined grooves A5252, the corresponding centripetal sliders 521 slide to the centripetal ends of the centripetal chute 511, so that the corresponding two clamping blocks 522 clamp the surface of the aluminum alloy profile. The other two movable posts A523 respectively move to the other ends of the two centripetal arc grooves A5251, and the corresponding two clamping blocks 522 maintain the clamping state on the surface of the aluminum alloy profile. Two of the movable posts A523 respectively move from the centripetal ends of the two positive inclined grooves A5252 to one end of the two centripetal arc grooves B5254, and the other two movable posts A523 respectively move from the other ends of the two centripetal arc grooves A5251 to the eccentric ends of the reverse inclined grooves A5253, so that the four clamping blocks 522 can be clamped alternately in pairs, enabling the electroplating of the outer surface of the aluminum alloy profile to be divided into two times, facilitating different electroplating requirements for different positions on the surface of the aluminum alloy profile. For example, for a decorative aluminum alloy profile that requires striped two-color electroplating on the outer surface, the electroplating can be first carried out on the unclamped part of the aluminum alloy profile, and then the aluminum alloy profile is transferred to another electroplating tank. Through the above operations, the other two clamping blocks 522 clamp and block the electroplated position, and the electroplating solution in the other electroplating tank is used to electroplate the unplated position. The fixing method of electroplating can be selected according to the actual electroplating requirements.

[0058] In an embodiment of the present invention, the tensioning assembly 53 includes an adjusting circular plate 534 and eight movable posts B531. The movable posts B531 are movably arranged on the centripetal guide groove 512. A gear A532 meshingly connected with the tooth groove 513 is fixedly arranged on the movable posts B531. A tensioning block 533 is fixedly arranged at the bottom end of the movable posts B531. The eight clamping blocks 522 can enclose a covering tensioning cavity. Both ends of the clamping blocks 522 are in an arc structure. The adjusting circular plate 534 is rotatably arranged on the inner edge surface of the adjusting ring plate 524. Eight displacement guide grooves B535 are arranged in an annular equidistant structure at the upper bottom end of the adjusting circular plate 534. The eight movable posts B531 are all movably connected with the displacement guide grooves B535. Through the structural design of the tensioning assembly 53 of the present invention, when the adjusting circular plate 534 is rotated, the eight displacement guide grooves B535 cause the eight movable posts B531 to respectively drive the eight tensioning blocks 533 to move centripetally. The relative movement of the gear A532 with respect to the tooth groove 513 causes the gear A532 to drive the movable posts B531 and the adjusting ring plate 524 to rotate. When the movable posts B531 move to the eccentric ends of the displacement guide grooves B535, the eight tensioning blocks 533 enclose a covering tensioning cavity to fixedly tension the inner surface of the aluminum alloy profile in a covering manner.

[0059] In an embodiment of the present invention, the displacement guide groove B535 is formed by connecting eight guiding channels in series from head to tail. The displacement guide groove B535 includes an eccentric arc groove B5351, and a positive inclined groove B5352 and a reverse inclined groove B5353 are respectively and communicatively provided at both ends of the eccentric arc groove B5351;

[0060] Among them, the active angles of the centripetal arc groove A5251, the positive inclined groove A5252, the reverse inclined groove A5253, the centripetal arc groove B5254, the eccentric arc groove B5351 and the positive inclined groove B5352 are equal. The active angle of the centripetal arc groove A5251 of the present invention refers to the rotation angle of the centripetal arc groove A5251 when the active column A523 moves from one end of the centripetal arc groove A5251 to the other end. The active angles of the positive inclined groove A5252, the reverse inclined groove A5253 and the centripetal arc groove B5254 are the same as the above. The active angle of the eccentric arc groove B5351 refers to the rotation angle of the eccentric arc groove B5351 when the active column B531 moves from one end of the eccentric arc groove B5351 to the other end. The active angle of the positive inclined groove B5352 is the same as the above. By setting the active angles of the centripetal arc groove A5251, the positive inclined groove A5252, the reverse inclined groove A5253, the centripetal arc groove B5254, the eccentric arc groove B5351 and the positive inclined groove B5352 to be equal, on the premise that the inner and outer surfaces of the aluminum alloy profile are electroplated and the electroplating of the outer surface of the aluminum alloy profile is divided into two times, when two of the active columns A523 are respectively located at the eccentric ends of the two positive inclined grooves A5252, the other two active columns A523 are respectively located at one end of the two centripetal arc grooves A5251, and the active column B531 is located at the end of the eccentric arc groove B5351 far from the positive inclined groove B5352, the tensioning assembly 53 covers and tension-fixes the inner surface of the aluminum alloy profile, and two of the clamping blocks 522 clamp the outer surface of the aluminum alloy profile. 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 534 and the adjusting ring plate 524 are rotated simultaneously. When the two active columns A523 move from one end of the two centripetal arc grooves A5251 to the other end of the two centripetal arc grooves A5251 respectively, the active 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 and clamp the outer surface of the aluminum alloy profile, and the tensioning assembly 53 covers and tension-fixes the inner surface of the aluminum alloy profile. Continue to rotate the adjusting circular plate 534 and the adjusting ring plate 524 so that the active column B531 moves 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 active columns A523 move 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 active 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 two of the 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 position of the outer surface of the aluminum alloy profile. The aluminum alloy profile is moved to another electroplating tank to electroplate the unplated part of the aluminum alloy profile.

[0061] In an embodiment of the present invention, the reverse rotation assembly 54 includes a plurality of reverse triangular grooves 541 formed on the outer edge surface of the adjustment circular plate 534 in an annular and equally spaced structure. The groove depth of the reverse triangular grooves 541 gradually decreases in the counterclockwise direction. The reverse triangular grooves 541 and the inner edge surface of the adjustment ring plate 524 form a forward limiting cavity. A limiting post A542 is movably arranged in the forward limiting cavity. The limiting post A542 is elastically connected to the deep part of the reverse triangular groove 541 through a spring A543;

[0062] The forward rotation assembly 55 includes positive triangular grooves 551 formed on the outer edge surface of the adjustment ring plate 524 in an annular and equally spaced structure. The groove depth of the positive triangular grooves 551 gradually decreases in the clockwise direction. The positive triangular grooves 551 and the inner edge surface of the rotation groove 41 form a reverse limiting cavity. A limiting post B552 is movably arranged in the reverse limiting cavity. The limiting post B552 is elastically connected to the deep part of the reverse limiting cavity through a spring B553. Through the structural design of the reverse rotation assembly 54 and the forward rotation assembly 55 in the present invention, when the adjustment circular plate 534 rotates forward, under the frictional force of the inner edge surface of the adjustment ring plate 524, the movable post A523 has a force to move towards the reverse triangular groove 541, so that the adjustment circular plate 534 cannot rotate clockwise relative to the adjustment ring plate 524. Similarly, it can be known that the adjustment ring plate 524 cannot rotate counterclockwise. Therefore, when the adjustment circular plate 534 rotates clockwise, it drives the adjustment ring plate 524 to rotate clockwise. When the adjustment circular plate 534 rotates counterclockwise, the adjustment ring plate 524 does not rotate. And in the static state, the adjustment ring plate 524 cannot rotate clockwise relative to the adjustment circular plate 534. Therefore, the adjustment ring plate 524 is in a non-rotatable state, making the clamping state of the clamping assembly 52 stable after adjustment.

The chamfer at the top of the positioning column 73 facilitates the placement of the aluminum alloy profiles to be electroplated. The positioning column 73 positions the aluminum alloy profiles to be electroplated. When the fixing mechanism 5 fixes the aluminum alloy profiles, the fixing mechanism 5 descends. The bottom end of the tensioning assembly 53 contacts the top end of the positioning column 73, causing the positioning column 73 to slide down along the sliding hole 72.
