Description

Technical Field

[0001] The present invention relates to the technical field of automobile component plastic electroplating, in particular to an electroplating production line for processing automobile interior and exterior trims. Background Art

[0002] In recent years, with the rapid development of the automotive, electrical, household appliance, and jewelry industries, the technology for electroplating metal on plastic surfaces has also continued to develop. Electroplated plastic products combine the characteristics of plastic and metal, not only achieving a beautiful appearance but also significantly improving the physical and mechanical properties of the products, imparting new properties such as electrical conductivity, magnetic permeability, and weldability. Consequently, plastic electroplating has become a key process in plastic decoration. To electroplate metal on a plastic surface, the plastic surface must first be coated with a conductive film—metallized. This involves pre-treating the plastic surface—activating it. To ensure a good bond between the coating and the plastic substrate, the plastic substrate must be activated. Plastic substrate activation and surface metallization techniques significantly impact the adhesion, stability, and aesthetics of the electroplated metal film on the plastic surface. They also influence coating properties such as the conductivity and lifespan of the deposited layer.

[0003] In traditional plastic electroplating, the plastic to be electroplated is fixed inside the electroplating solution. This will make the contact between the metal surface and the electroplating solution uneven, which can easily cause different plating thicknesses. In addition, some electroplating processes take a long time, and the precipitation of the electroplating solution will affect the quality of the plating. Summary of the Invention

[0058] To further understand the features, technical means, and the specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0059] As Figures 1-10 shown, the present invention provides:

[0060] An electroplating production line for processing automotive interior and exterior trim parts, including a roughening mechanism, a chemical plating mechanism, and an electroplating mechanism. The electroplating mechanism includes an electroplating bath 1 and an anode rod 2 disposed in the electroplating bath 1. The electroplating mechanism further includes a spoiler 3 and a driving component 4. The spoiler 3 is disposed in the electroplating bath 1. The spoiler 3 is arc-shaped and can be deformed under force. The axis of the spoiler 3 extends in the vertical direction. The two sides of the spoiler 3 extending in the vertical direction are fixedly disposed in the electroplating bath 1. The driving component 4 is disposed outside the electroplating bath 1, and the output end of the driving component 4 is in transmission connection with the spoiler 3.

[0061] It further includes a fixture for hanging parts, and the fixture with the parts hung thereon passes through the roughening mechanism, the chemical plating mechanism, and the electroplating mechanism in sequence;

[0062] There is also a degreasing mechanism before the roughening mechanism. The degreasing mechanism is used to clean the surface of plastic parts and remove grease, dust, sweat and other substances on the surface of plastic parts. Degreasing is not only related to the adhesion between the electroplating layer and the plastic substrate, but also to the appearance of the plating layer and various properties of the plating layer.

[0063] The roughening mechanism is used to form depressions with a diameter of 0.2um to 1um on the plastic surface, making the surface of the part micro-rough, increasing the contact area between the electroplating surface and the injection molded part. Roughening improves the hydrophilicity of the plastic surface and forms an appropriate roughness, which can ensure good bonding between the plating layer and the plastic surface. Currently, chemical roughening is commonly used. The chemical roughening method uses the strong acidity of the roughening liquid to form depressions on the surface of the part.

[0064] After the roughened parts are washed with water, they are placed in a chemical plating mechanism to form a conductive film on the surface of the parts by chemical plating. The parts with the conductive film are then placed in an electroplating mechanism to electroplate the surface of the parts.

[0065] The hanger is placed in the electroplating tank 1, and the anode rod 2 and the hanger are energized. Since the cation concentration in the electroplating solution around the anode rod 2 is relatively high, it is necessary to guide the cations to be evenly distributed in the electroplating solution. The driving component 4 is started. Since the spoiler 3 is arc-shaped and its two sides extending in the vertical direction are fixedly arranged in the electroplating tank 1, the output end of the driving component 4 can guide the arc-shaped spoiler 3 to deform. When the spoiler 3 is deformed, it will stir the electroplating solution in the electroplating tank 1, thereby evenly distributing the cations near the anode rod 2 in the electroplating solution, thereby stirring the electroplating solution;

[0066] The present invention arranges an arc-shaped spoiler 3 in the electroplating tank 1, and starts the driving component 4 to guide the spoiler 3 to deform in the electroplating tank 1, thereby disturbing the electroplating solution and stirring it, so that the cations can be evenly distributed in the electroplating solution, and the electroplating layer on the surface of the part is more uniform.

[0067] like Figure 2 As shown, further:

[0068] The spoiler 3 is flexible and also includes four columns 5. The four columns 5 are relatively arranged in the electroplating pool 1. The columns 5 extend in the vertical direction. The spoiler 3 is arranged between two adjacent columns 5. The two sides of the spoiler 3 extending in the vertical direction are fixedly connected to the columns 5. The output end of the drive component 4 is transmission-connected to the side of the spoiler 3 facing the electroplating pool 1.

[0069] Since the spoiler 3 is flexible, flexibility means that the spoiler 3 deforms under force and cannot return to its original state after the acting force is removed. After the spoiler 3 is deformed by an external force, a driving assembly 4 is required to guide the spoiler 3 to deform or recover from deformation. Four columns 5 are relatively arranged in the electroplating bath 1 so that the two sides of the spoiler 3 extending in the vertical direction can be fixedly connected to two adjacent columns 5. Thus, the spoiler 3 can deform between the two columns 5. There are a total of four spoilers 3 among the four columns 5. The hanging tool is arranged between the four spoilers 3. When the driving assembly 4 is started, the four flexible spoilers 3 deform together, thereby being able to disturb the electroplating solution and making the cations evenly distributed in the electroplating solution.

[0070] As Figure 2 and Figure 3 shown, further:

[0071] The driving assembly 4 includes a rotating disk 401, a motor 402, a contact rod 403, a transmission frame 404, a connecting rod 405, and a spring 406.

[0072] The rotating disk 401 is rotatably arranged at the bottom of the electroplating bath 1. The axis of the rotating disk 401 extends in the vertical direction. The circumferential side of the rotating disk 401 is provided with convex arc surfaces 4011 and concave arc surfaces 4012 at intervals, and the convex arc surfaces 4011 and the concave arc surfaces 4012 are smoothly connected.

[0073] The motor 402 is arranged at the bottom of the electroplating bath 1, and the output shaft of the motor 402 is coaxially and drivingly connected to the rotating disk 401.

[0074] The contact rod 403 is slidably arranged at the bottom of the electroplating bath 1 along the radial direction of the rotating disk 401, and the contact rod 403 abuts against the circumferential side of the rotating disk 401 along the radial direction.

[0075] The transmission frame 404 is slidably arranged around the electroplating bath 1 along the radial direction of the rotating disk 401, and the bottom of the transmission frame 404 is fixedly connected to the contact rod 403.

[0076] The connecting rod 405 penetrates through the electroplating bath 1 along the radial direction of the rotating disk 401 and is slidably engaged with it. One end of the connecting rod 405 is fixedly connected to the surface of the spoiler 3 facing the inner wall of the electroplating bath 1, and the other end of the connecting rod 405 is fixedly connected to the transmission frame 404.

[0077] The spring 406 is sleeved on the connecting rod 405, and the two ends of the spring 406 respectively abut against the inner wall of the electroplating bath 1 and the surface of the spoiler 3 facing the inner wall of the electroplating bath 1.

[0078] When it is necessary to make the spoiler 3 continuously stir the plating liquid in the electroplating pool 1, the motor 402 is started, and its output shaft drives the rotating disk 401 to rotate at the bottom of the electroplating pool 1. Because the abutment rod 403 abuts against the circumference of the rotating disk 401 in the radial direction, and the spoiler 3 is elastically connected to the pool wall of the electroplating pool 1 through the connecting rod 405 and the spring 406, when the abutment rod 403 abuts against the concave arc surface 4012, the spoiler 3 is deformed by the guidance of the transmission frame 404, so that its concave surface faces the pool wall of the electroplating pool 1, and the rotating disk 401 rotates and abuts When one end of the rod 403 slides from the concave arc surface 4012 to the convex arc surface 4011, the spoiler 3 is deformed after overcoming the elastic force of the spring 406, and its convex surface faces the wall of the electroplating pool 1. The rotating disk 401 rotates again, and one end of the abutment rod 403 slides from the convex arc surface 4011 to the concave arc surface 4012. Under the elastic force of the spring 406, the spoiler 3 is deformed, and its concave surface faces the wall of the electroplating pool 1 again. During this deformation process, the spoiler 3 pushes the plating solution toward the hanger, thereby guiding the cations to be evenly distributed in the plating solution.

[0079] As some optional embodiments of the present invention, a roller is provided at one end of the abutment rod 403, and the abutment rod 403 rolls with the circumferential surface of the rotating disk 401 through the roller, thereby reducing the friction between the abutment rod 403 and the rotating disk 401, so that the rotating disk 401 can stably guide the abutment rod 403 to slide.

[0080] like Figure 2 As shown, further:

[0081] The spoiler 3 is elastic and also includes four columns 5. The four columns 5 are relatively arranged in the electroplating pool 1. The columns 5 extend in the vertical direction. The spoiler 3 is arranged between two adjacent columns 5. The two sides of the spoiler 3 extending in the vertical direction are fixedly connected to the columns 5. In the initial state, the outer arc surface of the spoiler 3 faces the inner wall of the electroplating pool 1, and the output end of the driving component 4 is transmission-connected to the side of the spoiler 3 facing the inner wall of the electroplating pool 1.

[0082] Elasticity refers to the property that the spoiler 3 is deformed by force and can return to its original shape after the force is lost. Because the spoiler 3 is elastic, the spoiler 3 is deformed after being acted upon by an external force, and there is no need for a driving component 4 to guide the spoiler 3 to restore its deformation on its own; the four columns 5 are arranged oppositely in the electroplating tank 1, so that the two sides of the spoiler 3 extending in the vertical direction can be fixedly connected to the two adjacent columns 5, thereby allowing the spoiler 3 to deform between the two columns 5, and a total of four spoilers 3 are arranged between the four columns 5, and the hanger is arranged between the four spoilers 3. When the driving component 4 is started, the four flexible spoilers 3 are deformed together, thereby disturbing the plating solution, so that the cations can be evenly distributed in the plating solution.

[0083] As Figure 2 and Figure 3 shown, further:

[0084] The driving assembly 4 includes a rotating disk 401, a motor 402, an abutting rod 403, a transmission frame 404 and a connecting rod 405;

[0085] The rotating disk 401 is rotatably arranged at the bottom of the electroplating bath 1, the axis of the rotating disk 401 extends in the vertical direction, convex arc surfaces 4011 and concave arc surfaces 4012 are arranged at intervals on the circumferential side of the rotating disk 401, and the convex arc surfaces 4011 and the concave arc surfaces 4012 are smoothly connected;

[0086] The motor 402 is arranged at the bottom of the electroplating bath 1, and the output shaft of the motor 402 is coaxially and drivingly connected to the rotating disk 401;

[0087] The abutting rod 403 is slidably arranged at the bottom of the electroplating bath 1 along the radial direction of the rotating disk 401, and the abutting rod 403 abuts against the circumferential side of the rotating disk 401 along the radial direction;

[0088] The transmission frame 404 is slidably arranged around the electroplating bath 1 along the radial direction of the rotating disk 401, and the bottom of the transmission frame 404 is fixedly connected to the abutting rod 403;

[0089] The connecting rod 405 penetrates through the electroplating bath 1 along the radial direction of the rotating disk 401 and is slidably matched with it. One end of the connecting rod 405 is fixedly connected to the surface of the spoiler 3 facing the inner wall of the electroplating bath 1, and the other end of the connecting rod 405 is fixedly connected to the transmission frame 404.

[0090] When it is necessary to make the spoiler 3 continuously stir the electroplating solution in the electroplating bath 1, start the motor 402 to drive its output shaft to drive the rotating disk 401 to rotate at the bottom of the electroplating bath 1. Since the abutting rod 403 abuts against the circumferential side of the rotating disk 401 along the radial direction, and due to the elasticity of the spoiler 3 itself, the spoiler 3 is elastically connected to the inner wall of the electroplating bath 1 through the connecting rod 405. In the initial state, the outer arc surface of the spoiler 3 faces the inner wall of the electroplating bath 1. When the rotating disk 401 rotates and one end of the abutting rod 403 slides from the convex arc surface 4011 to the concave arc surface 4012, the spoiler 3 deforms after overcoming its own elastic force, and its concave surface faces the inner wall of the electroplating bath 1. During this deformation process, the spoiler 3 deflects the electroplating solution towards the fixture, so as to guide the cations to be evenly distributed in the electroplating solution. When the rotating disk 401 rotates again and the abutting rod 403 moves from the concave arc surface 4012 to the convex arc surface 4011, the spoiler 3 returns to its original shape under the action of its own elastic force, that is, the outer arc surface of the spoiler 3 faces the inner wall of the electroplating bath 1 again, so as to facilitate continuous stirring of the electroplating solution and make the cations evenly distributed in the electroplating solution.

[0091] As Figure 1 shown, further:

[0092] The spoiler 3 is evenly provided with water passing holes 301.

[0093] By arranging the water passing holes 301 on the spoiler 3, the resistance of the electroplating solution to the spoiler 3 is reduced, so that the spoiler 3 can be deformed stably.

[0094] Such as Figures 6-10 shown, further:

[0095] The electroplating mechanism further includes a defoaming component 6, and the defoaming component 6 includes a fixed cylinder 601, a rotating cylinder 602, an actuating cylinder 603, a positioning bolt 604 and a support plate 605;

[0096] The fixed cylinder 601 is fixedly arranged at the bottom of the electroplating bath 1, the axis of the fixed cylinder 601 extends in the vertical direction, and a wavy and end-to-end first guide groove 6011 is arranged on the inner circumferential surface of the fixed cylinder 601;

[0097] The rotating cylinder 602 is coaxially rotatably arranged in the fixed cylinder 601, a second guide groove 6021 extending along its axis is arranged on the circumferential surface of the rotating cylinder 602, a connecting disc 6022 coaxial with it is arranged at the bottom end of the rotating cylinder 602, and a transmission column 6023 passing through the electroplating bath 1 and rotatably matched with it is arranged at the bottom end of the connecting disc 6022, and the transmission column 6023 is coaxially rotatably connected with the rotating disc 401;

[0098] The actuating cylinder 603 is coaxially slidably arranged in the rotating cylinder 602;

[0099] The positioning bolt 604 penetrates through the actuating cylinder 603 in the radial direction and is fixedly connected with it. One end of the positioning bolt 604 sequentially passes through the second guide groove 6021 and the first guide groove 6011, and the positioning bolt 604 is slidably matched with the second guide groove 6021 and the first guide groove 6011;

[0100] The support plate 605 is horizontally arranged at the top end of the actuating cylinder 603, and a fixture 6051 for clamping the bottom end of the hanging tool is arranged at the top end of the support plate 605.

[0101] During electroplating, the inner holes of some parts are stepped. Bubbles will be generated during the electroplating of the parts. The bubbles in the inner holes of the parts are intercepted by the steps of the inner holes of the parts and accumulate at the steps of the inner holes of the parts. There will be a defect that the electroplating quality of the stepped inner holes of the parts is poor;

[0102] When the rotating disk 401 drives the connecting disk 6022 and the rotating cylinder 602 to rotate in the fixed cylinder 601 through the transmission column 6023, since the positioning bolt 604 is in sliding fit with the second guide groove 6021 and the first guide groove 6011, and the first guide groove 6011 is wavy and connected end to end, and the second guide groove 6021 extends in the vertical direction, the positioning bolt 604 slides along the moving direction of the intersection point of the first guide groove 6011 and the second chute, so that while the actuating cylinder 603 rotates, it will also stably lift and lower in the vertical direction. The hanger is fixed on the support plate 605 through the fixture 6051, so that the actuating cylinder 603 drives the support plate 605 and the hanger to rotate and lift, thereby increasing the probability of bubbles in the inner hole of the part being discharged outward, thereby improving the electroplating quality;

[0103] When the positioning bolt 604 slides from the trough of the first guide groove 6011 to its crest, the support plate 605 and the hanger move upward. When the positioning bolt 604 slides from the crest of the first guide groove 6011 to its trough, the support plate 605 and the hanger move downward;

[0104] Through the defoaming assembly 6, the present invention can effectively discharge the bubbles in the inner hole of the part outward from the part, thereby improving the electroplating quality of the stepped inner hole of the part.

[0105] As Figure 8 shown, further:

[0106] The fixture 6051 is provided with an expansion port and a limit port in sequence from top to bottom. The width of the expansion port is greater than the width of the limit port, and the limit port can be clamped with the bottom end of the hanger.

[0107] Through the expansion port, the bottom end of the hanger can be stably positioned in the limit port, so that the support plate 605 can be stably detachably connected to the hanger through the fixture 6051, facilitating the rotation and lifting of the hanger.

[0108] As Figure 6 and Figure 10 shown, further:

[0109] A ring groove 6024 coaxial with it is provided on the outer circumferential surface of the rotating cylinder 602; the defoaming assembly 6 further includes a sealing ring 606. The sealing ring 606 is sleeved on the ring groove 6024, and the sealing ring 606 is in interference fit with the inner circumference of the fixed cylinder 601.

[0110] The electroplating solution is likely to overflow outward through the gap between the fixed cylinder 601 and the rotating cylinder 602. By providing the ring groove 6024 on the outer circumferential surface of the rotating cylinder 602 and then sleeving the sealing ring 606 on the ring groove 6024, the sealing performance between the fixed cylinder 601 and the rotating cylinder 602 is improved, avoiding the problem of electroplating solution overflow.

[0111] As Figure 6As shown, further:

[0112] The defoaming component 6 further includes a bearing 607, and the transmission column 6023 is rotationally matched with the bottom of the electroplating bath 1 through the bearing 607.

[0113] The transmission column 6023 can stably rotate with the bottom of the electroplating bath 1 through the bearing 607, thereby improving the stability of the electroplating mechanism.

[0114] The above embodiments only represent one or several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
