Description

Technical Field

[0001] The invention relates to the technical field of electroplating, specifically to the technical field of plastic electroplating, and particularly to an electroplating device for processing automobile plastic parts. Background Art

[0002] Compared with metal parts, plastic electroplating products can not only achieve a good metal texture, but also reduce the weight of the products. While effectively improving the appearance and decorativeness of plastics, it also improves its electrical, thermal and corrosion resistance properties. Therefore, it is currently widely used in electroplating.

[0003] Based on the search for electroplating processing of plastic parts, a Chinese invention patent with authorization announcement number CN113604850B was found, which discloses a fully automatic plastic electroplating production line system and its working method, which batches plastic parts into the electroplating box, and then immerses the electroplating box in the electroplating solution. During the electroplating process, the electroplating box is driven to roll in the electroplating solution to make the plastic parts more efficiently electroplated. After the electroplating process is completed, the electroplating box is taken out, and then the electroplating rack is driven to rotate, thereby accelerating the draining of the plastic parts. At the same time, the air pump is used to spray the plastic parts to accelerate the drying of the plastic parts. However, there are still some problems. Disadvantages: Plastic parts are placed in the electroplating box in batches. On the one hand, during the electroplating process, even if the electroplating box can rotate, plastic parts will still come into contact and collide with each other, which can easily lead to electroplating dead corners and affect the quality of the electroplating results. This needs to be improved. On the other hand, during the draining process after the electroplating is completed, although the electroplating box can rotate and the air pump has a jet action, the plastic parts are placed in batches, which can easily affect the flow of the plating solution, that is, the draining. In addition, due to the shape limitations of the plastic parts, there may be irregular concave dead corners, etc., which make it very easy for the plating solution to remain. Therefore, the draining effect is poor and needs to be improved.

[0004] Based on the above, the present invention proposes an automotive plastic parts processing electroplating device. Summary of the invention

[0005] In order to solve the problems mentioned in the above background, the present invention provides an electroplating device for processing automobile plastic parts.

[0006] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows.

[0007] The electroplating device for processing automobile plastic parts includes a moving line, an electroplating tank and a suspension component. The electroplating liquid is stored in the electroplating tank. A plurality of electroplating tanks are arranged in an array along the extension direction of the moving line. The suspension component is used to pull the plastic parts in and out of the electroplating tanks. The moving line is used to pull the suspension component through the plurality of electroplating tanks in sequence.

[0008] As a further improvement and optimization of the present invention, a linear module 1 and two partitions are arranged above the electroplating tank. When the two partitions are close to each other and contact each other, they can form a cylindrical shape with openings at both ends. The linear module 1 is used to drive the two partitions to move away from or towards each other.

[0009] As a further improvement and optimization of the present invention, the suspension assembly includes a moving frame connected to a moving line and moved by being pulled by the moving line, a crossbeam bracket is slidably installed on the moving frame, the movement direction of the crossbeam bracket is vertically arranged, the crossbeam bracket is driven to move by a linear module 2 arranged on the moving frame, and a suspension component is arranged at the end of the crossbeam bracket.

[0010] As a further improvement and optimization of the present invention, the suspension component includes a suspension main shaft with a vertically arranged axis and installed at the end of the crossbeam bracket, the suspension main shaft can rotate around its own axis, a connecting seat is provided on the suspension main shaft, the outer surface of the connecting seat is provided with a suspension sub-shaft extending radially along the suspension main shaft, the suspension sub-shaft is in the shape of a hollow shaft and the internal area of ​​the suspension sub-shaft is connected to the internal area of ​​the connecting seat, a number of suspension sub-shafts are arranged in an array along the circumferential direction of the suspension main shaft, a rotating shaft is installed at the bottom of the suspension sub-shaft, the axis of the rotating shaft is arranged vertically, the rotating shaft can rotate around its own axis, a number of hooks are provided on the outside of the rotating shaft, the hooks are used to hang plastic parts, and a number of rotating shafts are arranged in an array along the axis direction of the suspension sub-shaft.

[0011] As a further improvement and optimization of the present invention, a transmission shaft is coaxially installed in the suspension sub-shaft, and the transmission shaft can rotate around its own axis, the input end of the transmission shaft extends into the connecting seat, and the upper end of the rotating shaft extends into the suspension sub-shaft;

[0012] The suspension main shaft is in the shape of a hollow shaft, a driving shaft is coaxially installed inside the suspension main shaft, and the upper end of the driving shaft extends out of the suspension main shaft and is connected to the crossbeam bracket;

[0013] The transmission shaft and the rotating shaft are connected to each other through power connecting parts, and the drive shaft and all transmission shafts are connected to each other through power transmission parts. When the suspension main shaft rotates, it will rotate with the suspension sub-shafts. During this process, the transmission shaft can be driven to rotate around its own axis through the power transmission parts.

[0014] As a further improvement and optimization of the present invention, the power transmission component includes a bevel gear 1 coaxially arranged on the driving shaft and a bevel gear 2 arranged on the transmission shaft, and a plurality of bevel gears are correspondingly arranged on the bevel gear 2, and the bevel gear 1 is meshed with the bevel gear 2.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] During electroplating, the present application can drive the plastic part to rotate around the axis of the suspension spindle while rotating around the axis of the rotating shaft, thereby achieving more efficient electroplating.

[0019] After the electroplating is completed, the plastic part can be driven to rotate around the axis of the suspension main shaft while rotating around the axis of the rotating shaft, and the electroplating liquid on the surface of the plastic part can be thrown out by centrifugal force. On the one hand, the two centrifugal forces can drain faster and the draining efficiency is higher. On the other hand, if the plastic part only rotates around the axis of the suspension main shaft but not around the axis of the rotating shaft, then due to the shape limitation of the plastic part, there are concave dead corners, etc., and some residual electroplating liquid is easy to stick to the concave dead corners under the action of centrifugal force and is difficult to be thrown out, resulting in incomplete draining. In contrast, in the present application, the plastic part can rotate around the axis of the suspension main shaft and around the axis of the rotating shaft. Therefore, this situation does not exist, and the draining efficiency and effect are better. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0030] Reference Figure 1-Figure 7 The automotive plastic parts processing electroplating device includes a moving line, a plating tank 200 and a suspension component 100. The plating liquid is stored in the plating tank 200. A plurality of plating tanks 200 are arranged in an array along the extension direction of the moving line. The suspension component 100 is used to pull the plastic parts in and out of the plating tank 200. The moving line is used to pull the suspension component 100 to pass through the plurality of plating tanks 200 in sequence. The moving line can be realized by existing technologies, such as existing screw linear motion technology or other existing production line moving technologies, etc., which will not be elaborated on.

[0031] Plastic electroplating: A certain processing method (usually chemical plating) is used to first obtain a conductive film on the surface of the plastic part, and then thicken it by electroplating. In addition, the composition of the metal layer plated on the surface of the plastic part is different. Therefore, multiple groups of electroplating tanks 200 need to be set up accordingly, with different plating solutions stored inside.

[0032] Reference Figure 2 and Figure 3 Two partitions are arranged above the electroplating tank 200, and are respectively named as partition 1 202 and partition 2 203. When the two partitions are close to each other and contact each other, they can form a cylindrical shape with openings at both ends. Furthermore, the two partitions are driven to move away from or towards each other through a linear module 201. The linear module 201 can be realized by the existing screw linear motion, which is not described in detail. For example, the screw technology is driven to rotate by motor technology. The screw is divided into two threaded segments with opposite thread rotation directions along the axis direction and a nut is arranged on each of the threaded segments at both ends. Therefore, the rotation of the screw can drive the two nuts to move towards or away from each other. The two nuts are respectively connected to two components, and the components and the surrounding frame form a sliding fit along the axis direction of the screw. The movement of the nut can move the components together, thereby achieving the purpose of driving the two components to move towards or away from each other.

[0033] Reference Figure 5-Figure 7 The suspension assembly 100 includes a moving frame 101 connected to a moving line and moved by the moving line. A crossbeam bracket 103 is slidably installed on the moving frame 101. The movement direction of the crossbeam bracket 103 is vertically arranged. The crossbeam bracket 103 is driven to move by a linear module 102 arranged on the moving frame 101. The linear module 102 can adopt the existing screw linear motion technology, which is not elaborated here. For example, the screw technology is driven to rotate by motor technology, and the rotation of the screw drives the nut to move on the screw. The nut is connected to the parts, and the parts and the surrounding frame form a sliding fit along the axis of the screw. The movement of the nut can move the parts together.

[0034] A suspension component is provided at the end of the crossbeam support 103 . When the suspension component 100 is moved by being pulled by the traction line, the suspension component can be located directly above the electroplating tank 200 .

[0035] Further, see Figure 7 The suspension component includes a suspension spindle 106 with a vertical axis and mounted at the end of the crossbeam bracket 103. The suspension spindle 106 can rotate around its own axis. A connecting seat 107 is provided on the suspension spindle 106. It should be noted that Figure 6 As shown, a plurality of connecting seats 107 can be arranged in an array along the axial direction of the suspension main shaft 106, which can increase the number of plastic parts suspended at one time. The figures of the present application show two connecting seats 107, which will not be described in detail.

[0036] The outer surface of the connecting seat 107 is provided with a suspension sub-shaft 108 extending radially along the suspension main shaft 106. The suspension sub-shaft 108 is in the shape of a hollow shaft and the inner area of ​​the suspension sub-shaft 108 is connected to the inner area of ​​the connecting seat 107. A plurality of suspension sub-shafts 108 are arranged in an array along the circumferential direction of the suspension main shaft 106.

[0037] A rotating shaft 109 is installed at the bottom of the suspension sub-axis 108. The axis line of the rotating shaft 109 is arranged vertically. The rotating shaft 109 can rotate around its own axis line. A plurality of hooks 110 are arranged on the outside of the rotating shaft 109. The hooks 110 are used to hang plastic parts. The hooks 110 can be realized by existing technology and will not be elaborated. A plurality of rotating shafts 109 are arranged in an array along the axis line direction of the suspension sub-axis 108.

[0038] A transmission shaft 111 is coaxially installed in the suspension sub-shaft 108 . The transmission shaft 111 can rotate around its own axis. The input end of the transmission shaft 111 extends into the connecting seat 107 , and the upper end of the rotating shaft 109 extends into the suspension sub-shaft 108 .

[0039] The suspension main shaft 106 is in the shape of a hollow shaft. A driving shaft 113 is coaxially installed inside the suspension main shaft 106 . The upper end of the driving shaft 113 extends out of the suspension main shaft 106 and is connected to the crossbeam bracket 103 .

[0040] The transmission shaft 111 and the rotating shaft 109 are connected to each other by a power connection member, such as a bevel gear technology.

[0041] The driving shaft 113 and all the transmission shafts 111 are connected to each other by power transmission parts 112. When the suspension main shaft 106 rotates, the suspension sub-shaft 108 will rotate with it. In this process, the transmission shaft 111 can be driven to rotate around its own axis through the power transmission parts 112, so that the rotating shaft 109 can rotate around its own axis, that is, the plastic part suspended on the hook 110 rotates around the axis of the suspension main shaft 106 while rotating around the axis of the rotating shaft 109. Furthermore, the power transmission part 112 includes a bevel gear 1 coaxially arranged on the driving shaft 113 and a bevel gear 2 arranged on the transmission shaft 111. There are several bevel gears arranged correspondingly. Bevel gear 1 is meshed with bevel gear 2. When the suspension sub-shaft 108 rotates with the suspension main shaft 106, bevel gear 2 also rotates with it. Since bevel gear 1 does not rotate, there is a speed difference between the two. Therefore, bevel gear 2 will also rotate around its own axis and rotate with the transmission shaft 111.

[0042] Working principle of the present invention:

[0043] The suspension assembly 100 is pulled by the moving line to be located directly above the electroplating tank 200, and then the linear module 2 102 is operated to drive the crossbeam support 103 to move downward, and the crossbeam support 103 moves downward with the suspension components and the plastic parts hung on the hook 110, so that the plastic parts are immersed in the electroplating solution, and then the plastic parts are electroplated. The electroplating is achievable by the existing technology and will not be described in detail. During the electroplating, by driving the suspension main shaft 106 to rotate, the plastic parts can be driven to rotate around the axis of the suspension main shaft 106 while rotating around the axis of the rotating shaft 109, so as to achieve more efficient electroplating;

[0044] After the electroplating is completed, the crossbeam support 103 is driven upward by the linear module 2 102 to place the plastic part between the two partitions. Then, the two partitions are driven closer to each other by the linear module 1 201 to form a cylindrical shape in which the plastic part is located. Then, the plastic part is driven to rotate around the axis of the suspension spindle 106 while rotating around the axis of the rotating shaft 109. The electroplating liquid on the surface of the plastic part is thrown out by centrifugal force. On the one hand, the two centrifugal forces can drain faster and the draining efficiency is higher. On the other hand, if the plastic part can only rotate around the axis of the suspension main shaft 106 and not around the axis of the rotating shaft 109, then due to the shape limitation of the plastic part, there is a concave dead corner, etc., and some residual plating liquid is likely to be close to the concave dead corner under the action of centrifugal force and difficult to be thrown out, and the drainage is not thorough. In contrast, in the present application, the plastic part can rotate around the axis of the suspension main shaft 106 and the axis of the rotating shaft 109. Therefore, this situation does not exist, and the drainage efficiency and effect are better.

[0045] The electroplating liquid thrown out will return to the electroplating tank 200 along the inner wall of the cylinder.

[0046] In the preferred embodiment, it can be seen from the above process description that the rotation speed of the plastic part around the axis of the rotating shaft 109 is determined by the rotation speed of the suspension spindle 106, that is, the centrifugal forces generated by the two rotating forces of the plastic part cannot be adjusted separately. In order to solve this problem, refer to Figure 6 A motor 104 and a motor 2 105 are installed on the crossbeam bracket 103. The motor 104 is dynamically connected to the suspension main shaft 106, and the motor 2 105 is dynamically connected to the drive shaft 113. The significance of this is that the suspension main shaft 106 is driven to rotate by the motor 104, thereby driving the plastic part to perform two rotational movements. At the same time, the drive shaft 113 is driven to rotate by the motor 2 105. The rotation of the drive shaft 113 will either reduce the rotation speed of the transmission shaft 111 or increase the rotation speed of the transmission shaft 111. Therefore, in this way, the rotation speed of the suspension main shaft 106 and the rotation speed of the rotating shaft 109 can be controlled and adjusted respectively.

[0047] In the preferred embodiment, in order to reduce the floor space, the layout of the two partitions will affect the up and down movement of the beam support 103. In order to solve this problem, refer to Figure 3 and Figure 4, the partition 203 is close to the movable frame 101, and the upper end surface of the partition 203 is penetrated with a notch, and the upper end of the partition 203 is coaxially extended with an arc plate, and the arc plate is coaxially provided with an arc hole, and the inner arc surface of the partition 203 is coaxially fitted with an inner arc plate 204, and two inner arc plates 204 are provided and are respectively located on both sides of the notch, and the upper end of the inner arc plate 204 extends with a convex seat 206, and the convex seat 206 passes through the arc hole and the two form a sliding fit, and the upper end of the partition 203 is also provided with a convex seat 1 205, and an elastic member 207 is provided between the convex seat 1 205 and the convex seat 206, and its elastic member 207 is provided between the convex seat 1 205 and the convex seat 206. It is used to drive the two inner arc plates 204 to have a movement tendency to move towards each other. The two inner arc plates 204 are each provided with an inclined surface on one side facing each other at the upper end, and the distance between the two inclined surfaces increases from bottom to top in the vertical direction. Therefore, when the beam bracket 103 moves downward, the two inner arc plates 204 will be pushed away from each other by the inclined surface, that is, the downward movement of the beam bracket 103 is not affected. When the beam bracket 103 completes the upward movement, the elastic member 207 releases the elastic force, so that the two inner arc plates 204 are close to each other and the reset is completed, so that the gap of the partition plate 203 is blocked, that is, the upward movement of the beam bracket 103 is not affected.

[0048] Furthermore, the elastic member 207 includes a sleeve rod movably connected to the second boss 206 and a sleeve movably connected to the first boss 205, the end of the sleeve rod slides into the sleeve and forms a sliding fit, and a spring is arranged between the end of the sleeve rod and the closed end of the sleeve.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
