Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically to an electroplating device for automotive trim parts that saves electroplating solution. Background Technology

[0002] Electroplating is a process that uses electrolysis to deposit a thin layer of another metal or alloy onto the surface of certain metals. The purpose is to prevent metal oxidation, improve wear resistance, conductivity, reflectivity, corrosion resistance, and enhance aesthetics. However, existing electroplating equipment for automotive parts often splashes the electroplating solution out during operation as the plating tank rotates and tumbles within the plating bath. This not only wastes the plating solution but also pollutes the environment and water sources.

[0003] Chinese Patent (Grant No. CN222476806U) discloses an electroplating equipment for automotive parts production. The equipment uses a cylinder to lower a lifting plate and an electroplating cylinder assembly (including baffles, connecting columns, a fixing plate, and the electroplating cylinder itself) fixed to the lifting plate, completely immersing the electroplating cylinder in the electroplating bath. Simultaneously, a moving mechanism moves along a track, driving the electroplating cylinder assembly. Because the rotating gear in the electroplating cylinder assembly meshes with a rack plate at the top of the electroplating bath, the rotating gear rotates during movement, which in turn drives the electroplating cylinder to rotate via a chain drive. This rotation of the electroplating cylinder ensures that the automotive parts inside receive uniform electroplating treatment. Furthermore, by using slots and sliding blocks on the side walls of the fixing plate, baffles are installed on the fixing plate, protecting the electroplating cylinder and effectively preventing electroplating solution from splashing out of the electroplating bath during rotation, thus avoiding waste and pollution to the environment and water sources. However, in this prior art, the electroplating barrel is always rotating during the electroplating process, which can easily lead to splashing of the electroplating solution.

[0004] Therefore, the present invention aims to provide an electroplating device for automotive trim parts that saves electroplating solution in order to solve the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned problems, an electroplating device for automotive trim parts that saves electroplating solution is provided. A moving mechanism moves the mounting box above the electroplating tank, and a cylinder pushes the electroplating cylinder into the electroplating solution. During immersion, a ratchet and a turntable work together to achieve step-by-step rotation. As the moving mechanism moves, gears and racks drive the electroplating cylinder to rotate in a specific direction. This combined motion of the electroplating cylinder improves electroplating uniformity and reduces electroplating solution consumption. It solves the problem of electroplating solution splashing caused by the electroplating cylinder constantly rotating during the electroplating process.

[0006] To address the problems of existing technologies, this utility model provides an electroplating device for automotive trim parts that saves electroplating solution. The device includes a moving track with a moving mechanism mounted on it. A mounting box is fixed to the bottom of the moving mechanism, and a cylinder is housed inside the mounting box. A lifting plate is mounted at the end of the cylinder. Fixed plates are located at both ends of the bottom of the lifting plate. An electroplating cylinder is rotatably connected between the fixed plates. One end of the electroplating cylinder has a ratchet with a limiting groove and a recess. A turntable is rotatably connected to the fixed plate near the ratchet. The turntable has a limiting block adapted to the limiting groove and a protrusion adapted to the recess. The rotating shaft of the turntable passes through the fixed plate, and a gear is located at the end of the shaft away from the turntable. An electroplating tank is located below the electroplating cylinder, and a rack is located on the side of the electroplating tank corresponding to the gear.

[0007] Preferably, the lifting plate is provided with movable rods at its four corners, and the top two ends of the fixed plate are provided with movable grooves adapted to the movable rods. A first return spring is sleeved on the movable rod.

[0008] Preferably, splash guards are installed at both ends of the fixing plate, guide grooves are provided at both ends of the fixing plate, and guide blocks are provided on the facing surfaces of the splash guards at both ends of the fixing plate.

[0009] Preferably, a positioning groove is provided at the bottom of the guide groove, and a through hole is provided on the fixing plate at a position corresponding to the positioning groove. A positioning rod is slidably connected in the through hole. When the splash guard is installed on the fixing plate, the positioning rod is inserted into the positioning groove, and a second return spring is sleeved on the positioning rod.

[0010] Preferably, the electroplating barrel has a feed inlet, and a cover is hinged to the feed inlet. The cover is fixed to the electroplating barrel by bolts.

[0011] Preferably, an installation groove is provided at the contact point between the electroplating tank and the rack, and an installation block is provided at the bottom of the rack, with the installation block inserted into the installation block.

[0013] Preferably, the sidewall of the electroplating cylinder has a number of through holes regularly distributed thereon.

[0014] The advantages of this utility model compared to the prior art are:

[0015] 1. In this utility model, the horizontal motion of the moving mechanism is transformed into the stepping rotation of the electroplating cylinder by the meshing of gears and racks with a turntable and ratchet mechanism, so that the workpiece can achieve intermittent directional rotation in the electroplating solution, prolonging the contact time of each surface and improving the uniformity of the coating. At the same time, the centrifugal force of rotation is used to remove excess electroplating solution, significantly reducing the amount carried out.

[0016] 2. In this utility model, a sliding snap-fit ​​structure of anti-splash plate, guide groove and positioning rod is adopted to form a semi-enclosed barrier to suppress splashing.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figures 1-8 As shown: An electroplating device for automotive trim parts that saves electroplating solution includes a moving track 1, a moving mechanism 2 on the moving track 1, an installation box 3 fixed at the bottom of the moving mechanism 2, a cylinder 4 inside the installation box 3, a lifting plate 5 installed at the end of the cylinder 4, fixed plates 6 at both ends of the bottom of the lifting plate 5, an electroplating cylinder 7 rotatably connected between the fixed plates 6, a ratchet 8 at one end of the electroplating cylinder 7, a limiting groove 9 and a groove 10 on the ratchet 8, a turntable 11 rotatably connected to the fixed plate 6 near the ratchet 8, a limiting block 12 adapted to the limiting groove 9 and a protrusion 13 adapted to the groove 10 on the turntable 11, the rotation shaft of the turntable 11 passes through the fixed plate 6 and a gear 14 is provided at the end of the rotation shaft away from the turntable 11, an electroplating tank 16 is provided below the electroplating cylinder 7, and a rack 15 is provided on the side of the electroplating tank 16 corresponding to the gear 14.

[0029] In the prior art, during electroplating operations, when the electroplating cylinder 7 is immersed in the electroplating tank 16, the electroplating cylinder 7 is constantly rotating, which easily leads to splashing of the electroplating solution. To solve this problem, in this application, the moving mechanism 2 moves the mounting box 3 along the track to above the electroplating tank 16. After the cylinder 4 inside the mounting box 3 is activated, it pushes the lifting plate 5 to move vertically downward, so that the electroplating cylinder 7, which is fixed at the bottom of the lifting plate 5, is gradually immersed in the electroplating tank 16. During the immersion process of the electroplating cylinder 7, its side ratchet 8 and the limiting block 12 of the turntable 11 form a dynamic engagement—when the turntable 11 is driven to rotate by the gear 14, the limiting block 12 is embedded in the limiting groove 9 of the ratchet 8, pushing the ratchet 8 to rotate in one direction; the protrusion 13 provides intermittent rotational resistance to the electroplating cylinder 7 through periodic meshing with the groove 10, forming a controllable stepping rotation.

[0030] When the moving mechanism 2 moves along the track, the gear 14 fixed to the shaft end of the turntable 11 meshes with the rack 15 on the side of the electroplating tank 16, converting the horizontal movement into the rotational movement of the gear 14. This rotation is transmitted to the ratchet 8 through the turntable 11, and finally converted into the directional rotation of the electroplating tank 7.

[0031] The combined motion of the electroplating barrel 7 includes two dimensions: vertical immersion and horizontal rotation. After vertical immersion is completed under the drive of cylinder 4, the electroplating barrel 7 achieves horizontal axial rotation through gear 14 and rack 15, allowing the workpiece inside the electroplating barrel 7 to form multi-angle contact in the electroplating solution. This rotary immersion method not only improves the uniformity of electroplating but also effectively removes excess electroplating solution from the workpiece surface through centrifugal force, significantly reducing the amount of electroplating solution carried out and achieving the goal of saving.

[0032] The integrated design of the entire device automates the entire process of workpiece loading, immersion plating, and rotary draining. After completing a single electroplating cycle, the moving mechanism 2 can return to its original position along the track, while the electroplating cylinder 7 is lifted and reset by the cylinder 4, preparing for the next work cycle. This mechanical linkage system significantly reduces electroplating solution consumption while ensuring electroplating quality by precisely controlling the movement trajectory of the electroplating cylinder 7.

[0033] Reference Figure 1 and Figure 2 As shown: The lifting plate 5 is provided with moving rods 17 at its four corners, and the top two ends of the fixed plate 6 are provided with moving grooves that are adapted to the moving rods 17. A first return spring is sleeved on the moving rods 17.

[0034] When gear 14 abuts against rack 15, the first return spring sleeved on moving rod 17 provides a certain buffer for fixed plate 6, avoiding damage caused by rigid contact between rack 15 and rack 15.

[0035] Reference Figures 1-4 As shown: splash guards 18 are installed at both ends of the fixing plate 6, guide grooves 19 are provided at both ends of the fixing plate 6, and guide blocks 20 are provided on the facing surfaces of the splash guards 18 at both ends of the fixing plate 6.

[0036] The splash guard 18 slides along the guide groove 19 on the fixed plate 6 via the guide block 20, forming a semi-enclosed barrier around the cylinder, which effectively suppresses the splashing and diffusion of the electroplating solution when it is rotated or lifted.

[0037] Reference Figures 1-4 As shown: The bottom of the guide groove 19 is provided with a positioning groove 21, and the fixing plate 6 is provided with a through hole at the position corresponding to the positioning groove 21. A positioning rod 22 is slidably connected in the through hole.

[0038] When the splash guard 18 is installed on the fixed plate 6, the positioning rod 22 is inserted into the positioning groove 21, and a second return spring is sleeved on the positioning rod 22.

[0039] The positioning groove 21 at the bottom of the guide groove 19 and the positioning rod 22 constitute a quick positioning and locking mechanism for the splash guard 18. When the splash guard 18 slides into the guide groove 19 through the guide block 20, the positioning rod 22 in the through hole of the fixing plate 6 automatically inserts into the positioning groove 21 under the preload of the second reset spring, forming a mechanical engagement.

[0040] Reference Figure 5 As shown: The electroplating cylinder 7 has a feed inlet 23, and a cover 24 is hinged to the feed inlet 23. The cover 24 is fixed to the electroplating cylinder 7 by bolts.

[0041] The feed port 23 is connected to the cover 24 by a hinge, which can rotate around the axis to open and close. When loading workpieces, it is fully opened to provide ample operating space, and during the electroplating process, it is closed by bolt fastening.

[0042] Reference Figure 7 and Figure 8 As shown: The electroplating tank 16 and the rack 15 have an installation groove 25 at the contact point, and the rack 15 has an installation block at the bottom, which is inserted into the installation groove 25.

[0043] After the mounting block is embedded in the mounting slot 25, the rack 15 and the electroplating tank 16 are quickly aligned and installed through the complementary fit of their geometric shapes.

[0044] Reference Figure 8 As shown: threaded holes are provided on both sides of the mounting groove 25, and mounting holes are provided on both sides of the rack 15. The rack 15 is installed on the side of the electroplating tank 16 by bolts.

[0045] When the mounting block at the bottom of the rack 15 is inserted into the mounting groove 25, the bolts on both sides pass through the mounting holes of the rack 15 and are screwed into the threaded holes of the electroplating tank 16, forming a multi-point rigid connection.

[0046] Reference Figures 1-8 As shown: Several through holes are regularly distributed on the side wall of the electroplating cylinder 7.

[0047] When the electroplating cylinder 7 is immersed in the electroplating bath 16, the electroplating solution quickly seeps into the cylinder through the through hole, ensuring that the surface of the workpiece is in full contact with the electrolyte.

[0048] The electroplating device for automotive trim parts provided by this utility model achieves efficient electroplating and electroplating solution conservation through a composite motion of vertical immersion plating and intermittent rotation. During operation, the moving mechanism 2 transports the mounting box 3 along the track to above the electroplating tank 16. The cylinder 4 drives the lifting plate 5 to vertically immerse the electroplating cylinder 7 into the electroplating tank 16. The moving rods 17 at the four corners of the lifting plate 5 and the first return spring buffer the downward pressure, preventing rigid collisions. When the moving mechanism 2 moves horizontally, the gear 14 meshes with the rack 15 on the side of the electroplating tank 16, driving the turntable 11 to rotate. The limiting block 12 on the turntable 11 embeds into the limiting groove 9 of the ratchet 8, pushing the electroplating cylinder 7 to rotate unidirectionally. Simultaneously, the protrusion 13 periodically meshes with the groove 10 of the ratchet 8, forming resistance, causing the electroplating cylinder 7 to rotate intermittently, extending the contact time between the workpiece and the electroplating solution, and improving the uniformity of the plating layer. The through holes on the side wall of the electroplating cylinder 7 promote rapid penetration of the electroplating solution, ensuring sufficient contact with the workpiece. During rotation, centrifugal force throws out excess electroplating solution, reducing the amount carried over. The splash guards 18 on both sides of the fixed plate 6 slide open via guide grooves 19 to form a semi-enclosed barrier. The positioning rods 22 at the bottom of the guide grooves 19 automatically engage with the positioning grooves 21 under the action of the second reset spring, locking the splash guards 18 in position to prevent splashing. After electroplating is complete, the moving mechanism 2 resets, and the cylinder 4 lifts the electroplating cylinder 7, completing the automatic cycle. The entire system integrates loading, immersion plating, and rotational draining through mechanical linkage, balancing electroplating quality with electroplating solution conservation.

[0049] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
