Description

Technical Field

[0001] This application relates to the technical field of electroplating, and more specifically, it relates to a carrier basket for electroplating. Background Art

[0002] During the electroplating process, the parts to be electroplated usually need to be suspended or placed in a carrier basket (also known as a hanging basket or electroplating basket) and immersed in the electroplating solution for electroplating. Traditional electroplating carrier baskets generally adopt a metal wire mesh or frame structure, and the parts are fixed by hooks or directly stacked. However, the prior art has the following problems:

[0003] 1. Easy part detachment: Most existing hanging baskets adopt an open design, and the parts are prone to loosen or even fall off during the flow, mechanical vibration or flipping of the electroplating solution, resulting in electroplating failure or part loss. For small, irregular or smooth-surface parts (such as precision hardware parts, electronic connectors, etc.), the fixing methods of traditional hanging baskets are difficult to provide stable support.

[0004] 2. Poor electroplating uniformity: When parts are stacked or closely arranged, it is easy to cause uneven electroplating layers due to contact occlusion, affecting product quality.

[0005] Currently, some improvement solutions adopt clamping, magnetic attraction or elastic fixing structures, but there are still problems such as complex structure, high cost or difficult maintenance. Therefore, there is an urgent need for an electroplating carrier basket with a simple structure, good anti-detachment effect and strong adaptability to improve the stability and efficiency of the electroplating process. Summary of the Invention

[0006] In order to solve the problems in the prior art that when using a metal wire mesh or frame structure and the parts are fixed by hooks or directly stacked, it is easy for the parts to become detached or the electroplating uniformity is poor, this application provides a carrier basket for electroplating.

[0007] A carrier basket for electroplating includes a rolling seat. One end of the rolling seat is provided with a rotation connection part, and the other end of the rolling seat is provided with a clamping limit part. The rotation connection part and the clamping limit part are coaxially arranged. A plurality of placement parts are evenly arranged in the circumferential direction of the rolling seat. Each placement part extends along the length direction of the rolling seat. A plurality of placement grooves for actively placing the electroplated parts are arranged in each placement part. The plurality of placement grooves are evenly spaced along the length direction of the rolling seat. A limit strip is detachably connected to the rolling seat at each placement part. The limit strip spans across the open ends of the plurality of placement grooves to limit the electroplated parts from detaching from the open ends of the placement grooves, and there is a gap between the limit strip and the open ends of the placement grooves to allow the electroplating solution to flush into the placement grooves.

[0008] Preferably, the rolling seat is made of a high-strength metal with an acrylic material covering its surface.

[0009] Preferably, a first flow channel is provided between two adjacent placement grooves in each placement part, and the two adjacent placement grooves are communicated through the first flow channel, and the size of the first flow channel is smaller than the size of the electroplated part.

[0010] Preferably, the multiple placement grooves provided in two adjacent placement parts are arranged in one-to-one correspondence, and a second flow channel is provided between the two placement grooves in correspondence, and the placement grooves in correspondence in two adjacent placement parts are communicated through the second flow channel, and the size of the second flow channel is smaller than the size of the electroplated part.

[0011] Preferably, a communication port is provided at the position of the limiting strip corresponding to the placement groove, and the size of the communication port is smaller than the size of the electroplated part.

[0012] Preferably, the rotary connection part is a circular column.

[0013] Preferably, the clamping and limiting part is a square column.

[0014] Beneficial technical effects of the present application: Place the electroplated part in the placement groove, rotate and connect with the fixed bracket in the electroplating tank through the rotary connection part, and tightly connect with the external rotary driving part through the clamping and limiting part, so as to realize that the rotary driving part drives the rolling seat to roll in the electroplating tank. Through the rolling of the rolling seat, the flow of the electroplating solution is stirred, and the electroplating solution enters the placement groove from the limiting strip and the opening end of the placement groove, so as to contact the parts in the placement groove for electroplating operation. Through the rotation of the rolling seat, the flow rate of the electroplating solution is relatively fast, and the fast-flowing electroplating solution can timely take away the hydrogen generated on the cathode surface, reducing the risk of hydrogen embrittlement; at the same time, it reduces the inclusion of impurity ions in the coating, avoids the local concentration being too low due to the depletion of ions, and is beneficial to improving the mass transfer efficiency, improving the uniformity and compactness of the coating. Through a plurality of placement grooves arranged at equal intervals, the electroplating operation of multiple parts can be realized simultaneously, which is beneficial to improving the production efficiency. And the parts are separated by the placement grooves and are independently arranged, avoiding the situation that the stacking of multiple parts affects the electroplating uniformity. The parts are restricted in the placement grooves by the limiting strip. Compared with the way of hanging and fixing the parts, the parts are not easily dropped into the electroplating tank under the impact of the electroplating solution and the movement of the carrying basket. The limiting strip and the rolling seat are detachably arranged to realize the placement operation of the parts, and the parts are accommodated in the grooves, which is suitable for the fixation of multiple types of parts, with strong adaptability. And the parts move in the placement groove when the rolling seat rotates, further making the parts contact the electrolyte fully without shielding dead angles, making the electroplating more uniform.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] Refer to Figure 1, A carrier basket for electroplating, comprising a rolling seat 1. One end of the rolling seat 1 is provided with a rotating connection part 2, and the other end of the rolling seat 1 is provided with a clamping and limiting part 3. The clamping and limiting part 3 and the rotating connection part 2 are coaxially arranged. A plurality of placing parts 4 are evenly arranged in the circumferential direction of the rolling seat 1. Each placing part 4 extends along the length direction of the rolling seat 1, and a plurality of placing grooves 5 for placing electroplated parts to move are arranged in each placing part 4. The plurality of placing grooves 5 are evenly spaced along the length direction of the rolling seat 1. A limiting strip 6 is detachably connected to the rolling seat 1 at each placing part 4. The limiting strip 6 straddles the open ends of the plurality of placing grooves 5. When placing the parts in the placing grooves 5, the limiting strip 6 is detached from the limiting part, and the parts are placed from the open ends of the placing grooves 5. After installing the limiting strip 6, the parts are limited by the limiting strip 6 from detaching from the placing grooves 5 at the open ends of the placing grooves 5. There is a gap between the limiting strip 6 and the open ends of the placing grooves 5 for the electroplating solution to flush into the placing grooves 5. In the above structure, the rolling seat 1 is rotationally connected to the fixed bracket in the electroplating tank through the rotating connection part 2, and is tightly clamped and connected to the external rotating driving part through the clamping and limiting part 3, so that the rotating driving part drives the rolling seat 1 to roll in the electroplating tank. By the rolling of the rolling seat 1, the electroplating solution is stirred to flow. The electroplating solution enters the placing grooves 5 from the gap between the limiting strip 6 and the open ends of the placing grooves 5, so as to contact the parts in the placing grooves 5 for electroplating operations. Due to the rotating action of the rolling seat 1, the flow rate of the electroplating solution is relatively fast. The fast-flowing electroplating solution can timely carry away the hydrogen generated on the cathode surface, reducing the risk of hydrogen embrittlement; at the same time, it reduces the inclusion of impurity ions in the coating, avoids the local concentration being too low due to the depletion of ions, which is beneficial to improving the mass transfer efficiency, improving the uniformity and density of the coating. Through the plurality of placing grooves 5 arranged at uniform intervals, electroplating operations on multiple parts can be carried out simultaneously, which is beneficial to improving the production efficiency. And the parts are separated by the placing grooves 5 and are independently arranged, avoiding the situation that the stacking of multiple parts affects the electroplating uniformity. The parts are restricted in the placing grooves 5 by the limiting strip 6. Compared with the way of hanging and fixing the parts, the parts are not easily dropped into the electroplating tank under the impact of the electroplating solution and the movement of the carrier basket. And the parts are accommodated in the grooves, which is suitable for fixing various types of parts, with strong adaptability. And the parts move in the placing grooves when the rolling seat 1 rotates, further making the parts contact the electrolyte fully without shielding dead angles, making the electroplating more uniform.

[0021] In order to enable the rolling seat 1 to have sufficient support strength and prevent the rolling seat 1 from reacting with the electroplating solution and consuming the electroplating solution, in this embodiment, the rolling seat 1 is supported by a high-strength metal with an acrylic material covering its surface.

[0022] Refer to Figure 1In order to make the parts contact with the electroplating liquid more fully and make the electroplating layer more uniform, in this embodiment, a first circulation channel 7 is arranged between two adjacent placement grooves 5 of each placement part 4, and the multiple placement grooves 5 arranged in the two adjacent placement parts 4 are arranged to be arranged in a one-to-one alignment, and a second circulation channel 8 is arranged between the two aligned placement grooves 5, and the limiting strip 6 is provided with a connecting port 61 at the position of the aligned placement groove 5, and the adjacent placement grooves 5 in the placement part 4 are connected through the first circulation channel 7, and a group of aligned placement grooves 5 in the adjacent placement part 4 are connected through the second circulation channel 8, and the placement groove 5 is directly connected to the electroplating tank through the connecting port 61, so that the electroplating liquid has a larger area of ​​passage and more flow directions to enter the placement tank to contact the workpiece, thereby achieving more sufficient contact between the parts and the electroplating liquid and making the electroplating layer more uniform. In order to prevent the parts from escaping from the placement grooves 5, the sizes of the first circulation channel 7, the second circulation channel 8, and the connecting port 61 are all set to the size of the electroplated parts in rainy weather.

[0023] Reference Figure 1 Furthermore, in order to facilitate disassembly and assembly, the rotating connecting part 2 in this embodiment is a circular column, and the clamping limit part 3 is a square column. In specific operation, a semicircular groove is provided on the groove wall on one side of the electroplating tank, and a rotating driving member is provided on the groove wall on the other side of the electroplating tank. The rotating driving member is a combination of a motor and a main shaft. A square groove is provided on the end of the main shaft. The circular column is placed in the semicircular groove, and the circular column is supported by the semicircular groove for rotation and pushes the rolling seat 1 so that the circular column can move axially in the semicircular groove, so that the square column penetrates into the square groove and cooperates with the square groove to realize the limit clamping. The motor drives the main shaft to rotate to realize the rotation of the rolling seat 1. After electroplating, the rolling seat 1 is pushed away from the main shaft to make the square column disengage from the square groove, and the rolling seat 1 can be pulled out of the electroplating tank, which is more convenient.

[0024] Reference Figures 1-3, Further, the specific composition structure of the rolling seat 1 is disclosed in this embodiment. Electroplating is performed on the scroll disk. The rolling seat 1 includes a central shaft 11, an end fixing plate 12, a forming plate 13, a connecting strip 14, and a locking assembly 15. The forming plate 13 includes a square plate body 131 and four connecting plate bodies 132 integrally provided on the peripheral wall of the square plate body 131. The four connecting plate bodies 132 are evenly arranged around the center of the middle square plate body 131. A slot 133 is formed between two adjacent connecting plate bodies 132. The number of forming plates 13 is multiple, and a first penetration hole 134 with a cross-section matching that of the central shaft 11 is provided at the center of the square plate body 131 of each forming plate 13. At the end of each connecting plate body 132 of the forming plate 13 away from the square plate body 131, a second penetration hole 135 with a cross-section matching that of the connecting strip 14 is provided. Multiple forming plates 13 are penetrated into the central shaft 11 through the first penetration holes 134 and are evenly spaced along the length direction of the central shaft 11, and every two forming plates 13 are symmetrically arranged. The number of connecting strips 14 is four, corresponding to the four connecting plate bodies 132 on each forming plate 13, and each connecting strip 14 is correspondingly penetrated into the second penetration hole 135 of a connecting plate body 132 of multiple forming plates 13. Multiple connecting plate bodies 132 are connected in series by the connecting strips 14, and these multiple connecting plate bodies 132 are all aligned.

[0025] The central shaft 11 and the connecting strip 14 are both formed by covering a steel bar with acrylic material. The forming plate 13 is formed by covering a steel sheet with acrylic material. After the central shaft 11 and the connecting strip 14 connect multiple forming plates 13 in series, the central shaft 11 and the connecting strip 14 are both heat-melt connected to the forming plate 13 through acrylic material, so that the central shaft 11 and the connecting strip 14 are connected to the forming plate 13 into an integral structure.

[0026] Refer to Figure 1 , The number of end fixing plates 12 is two, and they are both circular plates made of acrylic material. Third penetration holes 121 with cross-sections matching that of the central shaft 11 are provided at the centers of the two end fixing plates 12. One end of the central shaft 11 penetrates through one end fixing plate 12 through the third penetration hole 121, and the other end of the central shaft 11 penetrates through the other end fixing plate 12 through the third penetration hole 121. The end fixing plate 12 and the central shaft 11 are heat-melt connected into one body through acrylic material. One end of the four connecting strips 14 pointing in the same direction is heat-melt connected to one side surface of one end fixing plate 12 through acrylic material, and the other end of the four connecting strips 14 pointing in the same direction is heat-melt connected to one side surface of the other end fixing plate 12 through acrylic material. The rotating connection part 2 and the clamping and limiting part 3 are both made of acrylic material, and the rotating connection part 2 is formed at one end of the central shaft 11, and the clamping and limiting part 3 is formed at the other end of the central shaft 11.

[0027] Refer to Figure 1, in the above structure, a placement portion 4 of the rolling seat 1 is formed between two adjacent connecting bars 14, and a placement groove 5 is formed between the slots 133 corresponding to each pair of adjacent forming plates 13, and a first communication channel is formed through the slots 133, and a second communication channel is formed by the gap between two adjacent forming plates 13.

[0028] Referring to Figure 1 and Figure 3 , through-holes 122 penetrating through their own thickness are provided on the two end fixing plates 12 at the positions corresponding to the four placement portions 4. The cross-sectional shape and size of the through-holes 122 match the cross-sectional shape and size of the limiting strips 6. The number of limiting strips 6 is four, corresponding to the four through-holes 122 on each end fixing plate 12. One end of the limiting strip 6 penetrates into the through-hole 122 of one end fixing plate 12, and the other end of the limiting strip 6 penetrates into the through-hole 122 of the other end fixing plate 12. And the length of the limiting strip 6 is set to be equal to the distance between the two opposite side surfaces of the two end fixing plates 12. The number of locking assemblies 15 is eight, and four locking assemblies 15 are respectively provided on the two opposite side surfaces of the two end fixing plates 12, and the four locking assemblies 15 are located at the positions corresponding to the four through-holes 122. The locking assembly 15 includes a blocking piece 151 and a bolt 152. The end fixing plate 12 is provided with a threaded hole on one side of each through-hole 122. The blocking piece 151 is provided with a fourth insertion hole and is sleeved on the outer wall of the bolt 152 through the fourth insertion hole. The bolt 152 is threadedly connected to the threaded hole. By turning the bolt 152, the nut of the bolt 152 presses against the blocking piece 151 to fix the blocking piece 151. By blocking the opening of the through-hole 122 of the end fixing plate 12 with the blocking piece 151, the limiting strip 6 is limited and fixed on the two end fixing plates 12, and by loosening the bolt 152, the blocking piece 151 is misaligned with the through-hole 122 to disassemble the limiting strip 6. The disassembly and assembly of the limiting strip 6 are relatively convenient, and the nut of the bolt 152 has a knob for easy turning.

[0029] Referring to Figure 2 , further, convex blocks 136 are protruded on the opposite side walls of two adjacent connecting plate bodies 132 on each forming plate 13, and a semi-circular groove 137 penetrating through the connecting plate body 132 is provided between the convex blocks 136 and the corner positions of the connecting plate body 132.

[0030] The principle of the above-mentioned rolling seat 1 for fixing the scroll disk is as follows: The structure of the scroll disk generally includes a circular end plate, a scroll wrap provided on one side of the circular end plate, and a hub portion provided on the opposite side of the circular end plate. The distance between two adjacent forming plates is set to be less than the diameter of the circular end plate, so as to prevent the scroll disk from disengaging from the placement groove 5. The distance between the bumps 136 of two adjacent connecting plate bodies 132 on the forming plate 13 is set to be greater than the width of the hub portion. The shape of the slot 133 formed by two adjacent connecting plate bodies 132 on the forming plate is an inverted "eight" shape. The bumps 136 are arranged at the position where the distance between two adjacent connecting plate bodies 132 is less than the diameter of the circular end plate. When placing the turbine disk into the placement groove 5 formed by two adjacent forming plates, the top surface of the circular end plate abuts against the top surface of the bumps 136, and the hub portion is suspended between the two bumps 136. The limiting strip 6 is arranged at a position close to the top surface of the scroll wrap. The rolling seat 1 rolls in the electroplating tank, and the electroplating solution flows into the placement groove 5 through the first communication channel, the second communication channel, the communication port 61, and the gap between the limiting strip 6 and the open end of the placement groove 5 to contact the scroll disk. Since both the hub portion and the scroll wrap are suspended, the contact with the electroplating solution is uniform and the electroplating effect is good. There is an activity gap between the scroll wrap and the limiting strip 6 close to the top surface of the scroll wrap. When the scroll disk rolls on the rolling seat 1, it can move in the accommodation groove in the direction perpendicular to the central axis 11, which is convenient for the part of the bottom surface of the circular end plate in contact with the bumps 136 to leave the bumps 136 and contact the electroplating solution to obtain a covering coating. The close arrangement of the limiting strip 6 makes it not easy for the scroll disk to be axially displaced when moving in the direction perpendicular to the central axis 11, resulting in the hub portion not being able to be suspended. And the edge of the circular end plate is accommodated by the semi-circular groove 137, and the semi-circular groove 137 realizes the flow of the electroplating solution, so that the edge of the circular end plate can be covered with a coating, reducing the electroplating dead angle and making the electroplating effect of the scroll disk better.
