Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, specifically to an electroplating and electrophoresis device for automotive trim parts that facilitates continuous operation. Background Technology

[0002] In traditional electroplating processes, automotive trim parts are usually placed directly into the electroplating tank and injected with electroplating solution. However, the impact force when pouring the electroplating solution can easily cause the automotive trim parts to shift or collide with the electrode plate, affecting the plating quality and causing product damage.

[0003] Chinese patent (authorization announcement number CN222160423U) discloses an automated electroplating and electrophoresis device for brake disc surfaces. Its core working principle is as follows: A drive motor rotates a threaded drive rod. The drive rod and a connecting piece (moving block) are threaded together, causing the connecting piece to move laterally along the drive rod, thereby horizontally moving the lifting assembly suspending the brake disc above the electroplating tank. An adjusting motor drives a rotating rod with bidirectional threads to rotate, causing a symmetrical adjusting seat to move in the opposite direction along the rod. Through the linkage of pull rod one and pull rod two with the connecting seat, a "scissor-like" lifting structure is formed, driving the suspension frame to rise and fall vertically, allowing the brake disc to be immersed in or removed from the electroplating solution. The right-side rod of the connecting piece rolls on a pulley, while the left-side rod slides through a limiting rod, ensuring synchronization between left and right during movement and preventing deviation. The suspension frame supports the simultaneous suspension of multiple brake discs through a detachable hook design, and a sliding plate maintains lifting stability. After electroplating, a collection box in the recovery assembly traps residual electroplating solution on the brake disc surface and circulates it back to the electroplating tank through a return pipe, reducing waste. The entire process utilizes automated control to continuously feed, immerse, remove, and reset the brake discs, significantly reducing manual intervention and improving operational efficiency and coating quality. However, the simultaneous suspension of multiple brake discs increases the complexity of the device, thereby increasing the difficulty of maintenance.

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

[0005] To address the aforementioned issues, a convenient electroplating and electrophoresis device for automotive trim parts is provided for continuous operation. A motor drives a turntable to rotate, and edge protrusions engaging sliding grooves convert the circular motion into the horizontal reciprocating motion of the connecting frame. Simultaneously, the alternating lifting and lowering of the two support frames is controlled. While one side is immersed in the electroplating tank for processing, the other side moves to the loading / unloading position to replace the workpiece. A single power source enables continuous electrophoresis operations. This solves the problem of increased complexity and maintenance difficulties caused by the simultaneous suspension of multiple brake discs.

[0006] To address the problems of existing technologies, this utility model provides an electroplating and electrophoresis device for automotive trim parts that facilitates continuous operation. The device includes a base with suspension mechanisms at both ends. A movable groove is formed on the base. The suspension mechanism includes a support frame, and a connecting frame is provided at the bottom of the support frame at both ends of the base. The connecting frame is slidably connected to the movable groove, and a sliding groove is provided at the center of the connecting frame. An electroplating tank is located at the center of the base, and a turntable is rotatably connected to the bottom of the electroplating tank. A protrusion is provided near the edge of the turntable and is inserted into the sliding groove. A first motor is located at one end of the base, and the output shaft of the first motor is connected to a first roller. A second roller is located at the center of the turntable, and the first roller drives the second roller to rotate via a transmission belt. A lifting mechanism is provided on the support frame, and a suspension rod is connected to the bottom of the lifting mechanism.

[0007] Preferably, the lifting mechanism includes a threaded rod, the top of the support frame has a through hole adapted to the threaded rod, a threaded sleeve is provided above the through hole, a first gear is fixedly connected to the bottom of the threaded sleeve, a second motor is installed on the top of the support frame near the through hole, and the output shaft of the second motor is connected to a second gear that meshes with the first gear.

[0008] Preferably, the bottom end of the threaded rod is connected to a mounting base for installing the suspension rod, the top two ends of the mounting base are provided with guide rods, and the top two ends of the support frame are provided with guide grooves adapted to the guide rods, and the guide rods are inserted into the guide grooves.

[0009] Preferably, the mounting base has several through holes on its side, and the suspension rod is installed on the mounting base by bolts; when the suspension rod is installed on the mounting base, the bolts are inserted into the through holes.

[0010] Preferably, the connecting frame has several positioning slots at both ends, and the bottom of the support frame has a positioning block that matches the positioning slot, and the positioning block is inserted into the positioning slot.

[0011] Preferably, the positioning slot has a through hole on its side wall, the positioning block has a threaded hole on its side wall that matches the through hole, and the connecting bracket is mounted on the support bracket by bolts.

[0012] Preferably, each corner of the electroplating box is provided with a positioning rod, and the base is provided with a plug groove that matches the positioning rod, and the positioning rod is inserted into the plug groove.

[0013] Preferably, the threaded sleeve is provided with a protective shell to prevent the threaded sleeve from falling off.

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

[0015] 1. In this utility model, the rotational motion of a single motor is converted into the horizontal reciprocating motion of the suspension mechanism through the transmission cooperation between the turntable and the protrusion-guide groove of the connecting frame, so that the two side support frames alternately perform electroplating and loading / unloading processes. Compared with the prior art which requires multiple independent suspension mechanisms, this solution only requires one transmission system to achieve continuous operation, significantly simplifying the device structure and reducing manufacturing costs and maintenance difficulty.

[0016] 2. In this utility model, the lifting mechanism adopts a threaded rod-threaded sleeve threaded transmission and a guide rod-guide groove double-point symmetrical guiding constraint. Power is transmitted through a gear set and offset is limited, ensuring stable and reliable lifting of the suspension rod. Compared with traditional single-point guiding or pure threaded transmission lifting structures, this design effectively disperses lateral loads, reduces wear on the threaded pair, extends service life, and ensures that the workpiece does not shake or shift during electroplating.

[0017] 3. In this utility model, a multi-layered structural stability guarantee is formed through the bolted locking connection between the positioning plug and the slot, the rigid fit between the electroplating box positioning plug rod and the base insertion groove, and the axial limiting design of the threaded sleeve protective shell. Compared with the easily loosened plug-in or single fixing methods in the prior art, this solution resists vibration and inertial impact through the synergistic effect of mechanical constraints and thread pre-tightening, ensuring that each component maintains precise alignment and rigid connection during continuous operation, thereby improving the overall operational reliability.

[0026] 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.

[0027] Reference Figures 1-7 As shown: An electroplating and electrophoresis device for automotive trim parts that facilitates continuous operation includes a base 1, with suspension mechanisms 2 at both ends of the base 1. A movable groove 3 is formed on the base 1. The suspension mechanism 2 includes a support frame 4. A connecting frame 5 is provided at the bottom of the support frame 4 at both ends of the base 1. The connecting frame 5 is slidably connected to the movable groove 3. A sliding groove 6 is provided at the center of the connecting frame 5. An electroplating tank 7 is provided at the center of the base 1. A turntable 8 is rotatably connected to the bottom of the electroplating tank 7. A protrusion 9 is provided near the circular edge of the turntable 8 and is inserted into the sliding groove 6. A first motor 10 is provided at one end of the base 1. The output shaft of the first motor 10 is connected to a first roller 11. A second roller 12 is provided at the center of the turntable 8. The first roller 11 drives the second roller 12 to rotate via a transmission belt. A lifting mechanism 13 is provided on the support frame 4, and a suspension rod 14 is connected to the bottom of the lifting mechanism 13.

[0028] In the prior art, multiple suspension mechanisms 2 are required for continuous operation, which increases the complexity of the device and makes maintenance more difficult. To solve this problem, this application achieves continuous operation through mechanical transmission and structural cooperation. When the device is started, the first motor 10 at one end of the base 1 drives the first roller 11 to rotate, and transmits the power to the second roller 12 at the center of the turntable 8 through the transmission belt, causing the turntable 8 to rotate at a constant speed around the bottom axis of the electroplating tank 7. The protrusions 9 provided on the edge of the turntable 8 rotate synchronously with the turntable 8. Since the protrusions 9 are inserted into the sliding groove 6 at the center of the connecting frame 5, the rotational motion is converted into the periodic pushing and pulling action of the protrusions 9 on the sliding groove 6, forcing the connecting frame 5 to slide horizontally back and forth along the moving groove 3 on the base 1.

[0029] The sliding of the connecting frame 5 directly drives the synchronous movement of the support frames 4 at both ends of the base 1, thereby creating an alternating lifting and lowering motion trajectory for the automotive trim suspended on the support frames 4. When one support frame 4 immerses the trim into the electroplating tank 7 for electrophoretic treatment, the other support frame 4 slides outward to the loading and unloading station, facilitating the unloading of processed workpieces and the loading of new workpieces by the operators. As the turntable 8 continues to rotate, the protrusion 9 completes one bidirectional reciprocating motion for each revolution, and the two suspension mechanisms 2 alternately complete the electroplating process and the loading and unloading process.

[0030] Reference Figures 1-6 As shown: The lifting mechanism 13 includes a threaded rod 15. The top of the support frame 4 has a through hole adapted to the threaded rod 15. A threaded sleeve 16 is provided above the through hole. A first gear 17 is fixedly connected to the bottom of the threaded sleeve 16. A second motor 18 is installed on the top of the support frame 4 near the through hole. The output shaft of the second motor 18 is connected to a second gear 19 that meshes with the first gear 17.

[0031] When the second motor 18 starts, its output shaft drives the second gear 19 to rotate. Since the second gear 19 meshes with the first gear 17 at the bottom of the threaded sleeve 16, power is transmitted to the threaded sleeve 16 through the gear set, forcing the threaded sleeve 16 to rotate synchronously around its own axis. The threaded sleeve 16 is connected to the threaded rod 15, which is installed in the through hole at the top of the support frame 4, through a threaded engagement. The rotational motion of the threaded sleeve 16 is converted into the linear lifting and lowering of the threaded rod 15 in the vertical direction. The lifting and lowering action of the threaded rod 15 directly drives the automotive trim suspended on the support frame 4 to move up and down.

[0032] Reference Figures 1-6 As shown: The bottom end of the threaded rod 15 is connected to a mounting base 20 for mounting the suspension rod 14. The top two ends of the mounting base 20 are provided with guide rods 21. The top two ends of the support frame 4 are provided with guide grooves 22 that are adapted to the guide rods 21. The guide rods 21 are inserted into the guide grooves 22.

[0033] When the threaded rod 15 is driven to rotate by the second motor 18 and drives the mounting base 20 to rise and fall, the guide rods 21 at both ends of the top of the mounting base 20 are simultaneously inserted into the guide grooves 22 at the top of the support frame 4. The sliding fit between the guide rods 21 and the guide grooves 22 forms a vertical constraint, forcing the mounting base 20 to move along a straight path, avoiding rotational offset or swaying caused by threaded clearance or uneven load.

[0034] The axial guiding function of the guide rod 21 shares the lateral force borne by the threaded rod 15, reducing the wear of the threaded pair. At the same time, the guide structure with a double-point symmetrical layout balances the stress state of the mounting base 20 and the suspension rod 14.

[0035] Reference Figures 1-6As shown: The mounting base 20 has several through holes on its side, and the suspension rod 14 is installed on the mounting base 20 by bolts;

[0036] When the suspension rod 14 is installed on the mounting base 20, the bolt is inserted into the through hole.

[0037] The clamping force applied after the bolt passes through the hole makes the suspension rod 14 and the mounting base 20 form a rigid connection, ensuring that the workpiece is subjected to uniform force and has no displacement during lifting and electroplating.

[0038] Reference Figure 5 As shown: The connecting frame 5 has several positioning slots 23 at both ends, and the bottom of the support frame 4 has a positioning block 24 that is adapted to the positioning slot 23. The positioning block 24 is inserted into the positioning slot 23.

[0039] When the positioning block 24 at the bottom of the support frame 4 is inserted into the positioning slots 23 at both ends of the connecting frame 5, the tight fit between the block and the slot forms a horizontal constraint, limiting the relative displacement between the support frame 4 and the connecting frame 5. At the same time, the friction force of the slot sidewall resists the weight and load of the support frame 4 in the vertical direction, ensuring that the two maintain a rigid connection during the sliding process.

[0040] Reference Figures 1-5 As shown: the positioning slot 23 has a through hole on its side wall, the positioning block 24 has a threaded hole on its side wall that matches the through hole, and the connecting frame 5 is installed on the support frame 4 by bolts.

[0041] After the positioning block 24 is inserted into the positioning slot 23 of the connecting frame 5, the operator inserts the bolt horizontally through the through hole on the side wall of the slot and screws it into the threaded hole on the side wall of the block. The axial preload of the bolt forces the contact surface of the block and the slot to fit tightly, eliminating the insertion gap. At the same time, the thread engagement forms a rigid connection to resist loosening of the insertion due to inertia or vibration during the operation of the device.

[0042] Reference Figures 4-7 As shown: The electroplating box 7 has positioning rods 25 at the four corners of its bottom, and the base 1 has a plug groove 26 that is adapted to the positioning rods 25. The positioning rods 25 are inserted into the plug groove 26.

[0043] When the electroplating tank 7 is placed in the center of the base 1, the positioning pins 25 at the four corners of its bottom are vertically inserted into the corresponding insertion slots 26 of the base 1. The tight fit between the pins and the slots forms a multi-directional geometric constraint, which restricts the translational and rotational freedom of the electroplating tank 7 in the horizontal plane. At the same time, the pins axially support the weight of the electroplating tank 7 and the load of the internal liquid, preventing the tank from shifting due to vibration or liquid impact during equipment operation.

[0044] Reference Figure 6As shown: The threaded sleeve 16 is provided with a protective shell 27 to prevent the threaded sleeve 16 from falling off.

[0045] The protective housing 27 is fixed to the top of the support frame 4, completely enclosing the threaded sleeve 16 in its internal cavity. The side wall of the protective housing 27 has an opening corresponding to the meshing position of the second gear 19, ensuring that the power transmission between the first gear 17 and the second gear 19 is not obstructed. At the same time, the inner walls of the top and bottom of the protective housing 27 abut against the end face of the threaded sleeve 16, forming an axial limit to prevent the threaded sleeve 16 from axially moving or even falling off during rotation due to vibration or load changes.

[0046] This utility model provides an electroplating and electrophoresis device for automotive trim parts that facilitates continuous operation. When the device is started, a first motor 10 at one end of the base 1 drives a first roller 11 to rotate. Power is transmitted via a transmission belt to a second roller 12 at the center of a turntable 8, causing the turntable 8 to rotate uniformly around the axis at the bottom of the electroplating tank 7. The protrusions 9 on the edge of the turntable 8 rotate synchronously with it. Since the protrusions 9 are inserted into the sliding groove 6 at the center of the connecting frame 5, the rotational motion of the turntable 8 is converted into a periodic pushing and pulling action of the protrusions 9 on the sliding groove 6, forcing the connecting frame 5 to slide horizontally back and forth along the moving groove 3 on the base 1. The sliding of the connecting frame 5 directly drives the support frames 4 at both ends of the base 1 to move synchronously, causing the suspension mechanisms 2 on both sides to work alternately: when one support frame 4 immerses the automotive trim part in the electroplating tank 7 for electrophoresis treatment, the other support frame 4 slides outward to the loading and unloading station, allowing the operator to unload the electroplated workpiece and load a new workpiece. As the turntable 8 continues to rotate, the protrusion 9 completes one revolution and achieves one bidirectional reciprocating motion. The two side suspension mechanisms 2 alternately perform electroplating and loading / unloading processes, forming a continuous operation cycle.

[0047] The second motor 18 at the top of the support frame 4 drives the second gear 19 to rotate, which in turn drives the threaded sleeve 16, which meshes with the first gear 17, to rotate. The threaded sleeve 16 and the threaded rod 15 in the through hole of the support frame 4 are connected by threads, converting the rotational motion into the vertical lifting and lowering of the threaded rod 15. The mounting base 20 connected to the bottom end of the threaded rod 15 is bolted to the suspension rod 14, which is used to support the automotive trim. The guide rods 21 at both ends of the top of the mounting base 20 are inserted into the guide grooves 22 at the top of the support frame 4, forming a vertical constraint through a sliding fit. This prevents the threaded rod 15 from shifting or swaying due to lateral forces or uneven loads, ensuring the stability of the trim lifting and lowering process.

[0048] After the positioning blocks 24 at the bottom of the support frame 4 are inserted into the positioning slots 23 at both ends of the connecting frame 5, they are bolted through the through holes in the side walls of the slots and screwed into the threaded holes of the blocks to form a rigid connection, restricting the relative displacement between the support frame 4 and the connecting frame 5. The positioning rods 25 at the four corners of the bottom of the electroplating tank 7 are vertically inserted into the corresponding insertion slots 26 of the base 1, constraining the horizontal displacement of the electroplating tank 7 and bearing the weight of the tank and the liquid load. In addition, the protective shell 27 provided outside the threaded sleeve 16 covers the threaded sleeve 16, restricting its axial movement, and at the same time, it abuts against the end face of the threaded sleeve 16 through the inner walls at the top and bottom to prevent it from falling off.

[0049] Through the above-mentioned linkage mechanism, the device achieves the coordinated horizontal reciprocating motion and vertical lifting action of the suspension mechanism 2 under the drive of a single first motor 10. Combined with the positioning block 24, positioning rod 25 and other structures, the device ensures the motion accuracy of each component, and finally achieves continuous alternating operation of electroplating and loading / unloading processes, thereby improving work efficiency and reducing device complexity.

[0050] 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.
