Description

Technical Field

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

[0002] With the rapid development of the automotive industry, the quality requirements for the surface treatment of parts (especially electroplating processes) are increasing. Dewaxing before electroplating is a crucial pretreatment step that directly affects the uniformity of the electroplated layer and the final product quality. Currently, most dewaxing equipment on the market uses ultrasonic cleaning machines, but existing technology has significant shortcomings: the process of placing and removing parts in the cleaning solution is not convenient, resulting in low operational efficiency. Specifically, traditional equipment lacks height adjustment and tilting functions, requiring frequent manual intervention when immersing or removing parts from the cleaning solution, increasing operational complexity, extending the production cycle, and failing to meet the demands of efficient automated production.

[0003] Chinese patent (authorization announcement number CN222220545U) discloses a dewaxing device for electroplating automotive parts. This device achieves dewaxing of automotive parts through mechanical transmission and automated control. Specifically, its support component is fixed to the side of an ultrasonic cleaner, and the moving component consists of a drive motor and a threaded rod, precisely adjusting the depth of the receiving part immersed in the cleaning solution to ensure thorough dewaxing before lifting and draining the water. The drive component, driven by a servo motor, rotates the worm gear transmission 180° in a single rotation, moving the receiving part from the cleaning position to the pick-up and drop-off position, with automatic unloading coordinated by auxiliary components. The worm gear self-locking ensures stability, and protective components isolate corrosive substances. The process integrates height adjustment and rotation functions, reducing manual intervention and improving batch processing efficiency. However, the lifting mechanism in this prior art lacks synchronization, which can easily lead to damage to the receiving compartment during lifting.

[0004] Therefore, the present invention aims to provide a dewaxing device for electroplating automotive trim parts to solve the above-mentioned problems. Utility Model Content

[0005] To address the aforementioned issues, a dewaxing device for electroplated automotive trim parts is provided. This device utilizes a motor-driven roller linkage with a dual-axis gear system for synchronous rotation. A lifting platform and a counterweight are hinged at both ends of a chain. When the platform descends, the counterweight moves in the opposite direction to balance the load and reduce energy consumption; when the platform rises, the counterweight assists in lifting. The loading frame is immersed in an ultrasonic cleaner along with the platform, utilizing cavitation to peel off the wax layer. After cleaning, the motor flips to its original position to retrieve the parts. The counterweight mechanism and synchronous transmission design prevent wear caused by asynchrony between the two axes. Combined with ultrasonic technology, this achieves efficient and automated dewaxing of electroplated parts. It also solves the problem of damage to the storage compartment during lifting due to a lack of synchronization in the lifting mechanism.

[0006] To address the problems of existing technologies, this utility model provides a dewaxing device for electroplating automotive trim parts, comprising a base, a lifting mechanism at one end of the base, and an ultrasonic cleaner at the end of the base away from the lifting mechanism. The lifting mechanism includes a first motor located on the base away from the ultrasonic cleaner, a support frame between the first motor and the ultrasonic cleaner, a first rotating shaft rotatably connected to the support frame, a first roller connected to the output shaft of the first motor, a second roller connected to one end of the first rotating shaft, the first roller being connected to the second roller via a transmission belt, gears at both ends of the first rotating shaft, chains meshing with the gears, a counterweight hinged to one end of the chain, and a lifting platform hinged to the other end of the chain, with a loading frame on the lifting platform.

[0007] Preferably, the support frame has movable grooves on both side walls, and the counterweight is slidably connected to the movable grooves.

[0008] Preferably, a plurality of guide rods are provided between the top plate of the support frame and the base, and a guide groove adapted to the guide rods is provided on the lifting platform, and the guide rods are inserted into the guide grooves.

[0009] Preferably, a tilting mechanism is provided between the load and the lifting platform. The tilting mechanism includes a second rotating shaft that is rotatably connected to the lifting platform. A support member is installed on the second rotating shaft, and the end of the support member away from the second rotating shaft is connected to the load frame.

[0010] Preferably, one end of the second rotating shaft is provided with a worm gear, the worm gear is meshed with a worm, and a second motor is installed on the lifting platform, the output shaft of the second motor being connected to the worm.

[0011] Preferably, the second motor is fitted with a protective casing.

[0012] Preferably, the lifting platform is provided with a discharge port for tilting the loading frame.

[0013] Preferably, a guide rail is provided below the discharge port, and a material frame for loading workpieces poured from the loading frame is slidably connected on the guide rail.

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

[0015] 1. This utility model solves the problem of mechanical damage caused by asynchronous movement at both ends of the lifting platform by using a first motor, transmission belt, and coaxial double gear chain transmission system. The linkage design between the counterweight and the lifting platform utilizes gravity to balance the load, significantly reducing motor energy consumption while improving the stability and synchronization accuracy of the lifting process.

[0016] 2. This utility model adds a composite guiding structure consisting of a support frame moving groove, a guide rod, and a lifting platform guide groove. Through physical constraints, it eliminates the lateral offset of the counterweight and the horizontal degree of freedom deviation of the lifting platform, ensuring the precise alignment of the loading frame and the ultrasonic cleaning machine tank, and avoiding cleaning fluid splashing or workpiece collision damage caused by mechanical vibration or uneven force.

[0017] 3. This utility model integrates a worm gear-driven tilting mechanism and a discharge port guide rail system, realizing full automation of the workpiece cleaning, draining, and unloading process. The self-locking characteristic of the worm gear ensures the stability of the loading frame's tilting angle, and the sliding fit between the discharge port and the material frame supports continuous operation, reducing manual intervention. At the same time, the protective shell isolates corrosive liquids, extending the equipment's service life. Attached Figure Description

[0025] 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.

[0026] Reference Figures 1-6 As shown: A dewaxing device for electroplating automotive trim parts includes a base 1, a lifting mechanism 2 at one end of the base 1, and an ultrasonic cleaner 3 at the end of the base 1 away from the lifting mechanism 2. The lifting mechanism 2 includes a first motor 4 located at the end of the base 1 away from the ultrasonic cleaner 3. A support frame 5 is provided between the first motor 4 and the ultrasonic cleaner 3. A first rotating shaft 6 is rotatably connected to the support frame 5. A first roller 7 is connected to the output shaft of the first motor 4. A second roller 8 is connected to one end of the first rotating shaft 6. The first roller 7 is connected to the second roller 8 through a transmission belt. Gears 9 are provided at both ends of the first rotating shaft 6. A chain is meshed on the gears 9. A counterweight 10 is hinged to one end of the chain, and a lifting platform 11 is hinged to the other end of the chain. A loading frame 12 is provided on the lifting platform 11.

[0027] In existing technologies, the lifting system in a dewaxing device requires a high degree of synchronization; if the travel speeds at both ends of the device differ, it can cause mechanical damage to the lifting platform 11. To solve this problem, in the device of this application, when it is in operation, the first motor 4 located at one end of the base 1 starts to run, and the output shaft of the first motor 4 drives the first roller 7 to rotate. The first roller 7 transmits power to the second roller 8 through a transmission belt, driving the first rotating shaft 6, which is coaxial with the second roller 8, to rotate synchronously. The gears 9 at both ends of the first rotating shaft 6 rotate accordingly, and the chain meshing with the gears 9 forms a cyclic motion under the drive of the gears 9.

[0028] One end of the chain is hinged to the counterweight 10, and the other end is hinged to the lifting platform 11. When the first rotating shaft 6 drives the gear 9 to rotate, the direction of the chain's movement depends on the direction of rotation of the first motor 4. If the first motor 4 drives the chain to move the lifting platform 11 downward, the counterweight 10 moves upward synchronously, using its weight to balance the load on the lifting platform 11, thereby reducing the energy consumption of the first motor 4 and improving stability. Conversely, when the lifting platform 11 needs to rise, the first motor 4 reverses direction, and the counterweight 10 descends to provide auxiliary lifting force.

[0029] As the lifting platform 11 descends, its carrying frame 12 gradually immerses itself in the ultrasonic cleaner 3 at the other end of the base 1. The ultrasonic cleaner 3 generates a cavitation effect in the cleaning fluid through high-frequency vibration, using the impact force generated by the collapse of microbubbles to peel off the wax layer from the surface of the electroplated parts. After cleaning is completed, the first motor 4 reverses its rotation, driving the lifting platform 11 to rise and reset with the carrying frame 12, allowing the operator to remove the dewaxed workpiece.

[0030] The entire workflow combines mechanical transmission and ultrasonic technology to achieve automated lifting and efficient cleaning of electroplated parts. The design of the counterweight mechanism effectively optimizes the system's energy consumption and operational stability.

[0031] Reference Figure 1 and Figure 2 As shown: The support frame 5 has movable grooves 13 on both sides, and the counterweight 10 is slidably connected to the movable grooves 13.

[0032] The movable grooves 13 on both sides of the support frame 5 provide a fixed vertical path for the movement of the counterweight 10. When the chain is driven by the gear 9 to raise and lower the counterweight 10, the counterweight 10 is embedded in the movable groove 13 through its side sliding parts such as sliders or guide blocks, so that the counterweight 10 can only move in the vertical direction of the groove.

[0033] Reference Figures 1-4 As shown: A plurality of guide rods 14 are provided between the top plate of the support frame 5 and the base 1. The lifting platform 11 is provided with guide grooves 15 that are adapted to the guide rods 14, and the guide rods 14 are inserted into the guide grooves 15.

[0034] A number of guide rods 14 arranged between the top plate of the support frame 5 and the base 1 form a rigid vertical track, and the axial direction of the guide rods 14 is consistent with the movement path of the lifting platform 11. When the motor drive chain drives the lifting platform 11 to rise and fall, the guide groove 15 opened on the lifting platform 11 forms a sliding engagement with the guide rods 14. The structural design of the guide rods 14 passing through the guide grooves 15 ensures that the lifting platform 11 always moves along the axial direction of the guide rods 14 during the movement, effectively limiting the horizontal offset or rotation of the platform and ensuring the alignment accuracy between the loading frame 12 and the tank of the ultrasonic cleaning machine 3.

[0035] Reference Figures 1-4 As shown: A flipping mechanism 16 is provided between the load and the lifting platform 11. The flipping mechanism 16 includes a second rotating shaft 17 rotatably connected to the lifting platform 11. A support member 18 is installed on the second rotating shaft 17. One end of the support member 18 away from the second rotating shaft 17 is connected to the load frame 12.

[0036] When it is necessary to flip the container 12, the second rotating shaft 17 drives the support member 18 to rotate. Since the end of the support member 18 away from the second rotating shaft 17 is fixedly connected to the container 12, the rotational motion of the support member 18 is directly converted into the tilting motion of the container 12, so that the container 12 can be flipped around the axis of the second rotating shaft 17 at a certain angle.

[0037] Reference Figures 4-6As shown: One end of the second rotating shaft 17 is provided with a worm gear 19, which is meshed with a worm 20. A second motor 21 is installed on the lifting platform 11, and the output shaft of the second motor 21 is connected to the worm 20.

[0038] When the second motor 21 stops operating, the friction between the meshing surfaces of the worm 20 and the worm wheel 19 prevents the worm wheel 19 from rotating in the opposite direction due to the weight of the carrying frame 12 and the workpiece. This self-locking function allows the carrying frame 12 to be stably suspended at any tilting angle, preventing accidental changes in the workpiece's posture due to liquid flow or vibration during the cleaning process, while also reducing the continuous energy consumption required for the motor to maintain the angle.

[0039] Reference Figure 4 As shown: The second motor 21 is equipped with a protective shell 22.

[0040] The protective shell 22 can prevent the second motor 21 from being corroded by the liquid inside the ultrasonic cleaner 3.

[0041] Reference Figure 4 As shown: The lifting platform 11 is provided with a discharge port 23 for tilting the loading frame 12.

[0042] When the flipping mechanism 16 drives the carrying frame 12 to rotate around the second rotating axis 17 to an inclined state, the electroplated ornaments inside the carrying frame 12 slide along the inclined direction under the action of gravity and fall precisely into the preset collection container or conveyor belt through the discharge port 23.

[0043] Reference Figure 5 As shown: A guide rail 24 is provided below the discharge port 23, and a material frame 25 for loading workpieces tilted from the loading frame 12 is slidably connected on the guide rail 24.

[0044] In continuous cleaning operations, after the loading frame 12 completes the cleaning of a batch of workpieces, the material frame 25 can quickly receive and remove the workpieces, while simultaneously preparing to receive the next batch, without needing to stop the machine for emptying. Furthermore, the physical isolation design of the guide rail 24 prevents operators from directly contacting the ultrasonic cleaning area, reducing safety risks caused by accidental contact with high-temperature liquids or high-frequency vibrating equipment.

[0045] This utility model provides a dewaxing device for electroplated automotive trim parts. When the device is started, a first motor 4 on the base 1 drives a first roller 7 to rotate, which in turn drives a second roller 8 and a coaxial first rotating shaft 6 to rotate synchronously via a transmission belt. Gears 9 at both ends of the first rotating shaft 6 mesh with a chain to form a cyclic motion. One end of the chain is hinged to a counterweight 10, and the other end is hinged to a lifting platform 11. When the first motor 4 rotates in the forward direction, the chain pulls the lifting platform 11 downward, while the counterweight 10 rises synchronously, using the weight of the counterweight 10 to balance the platform load. In the reverse direction, the lifting platform 11 rises to its original position, and the counterweight 10 descends to assist in lifting. The lifting platform 11 drives the carrying frame 12 into an ultrasonic cleaner 3, where the cavitation effect generated by high-frequency vibration peels off the wax layer from the surface of the electroplated trim parts.

[0046] The sliding connection between the movable slots 13 on both sides of the support frame 5 and the counterweight 10 restricts the counterweight 10 to move only in the vertical direction, preventing lateral displacement. The guide rod 14 between the top plate of the support frame 5 and the base 1 passes through the guide slot 15 on the lifting platform 11, forming a rigid track, constraining the horizontal degree of freedom of the lifting platform 11, and ensuring its vertical lifting accuracy. The tilting mechanism 16, which connects the loading frame 12 and the lifting platform 11 through the second rotating shaft 17, enables angle adjustment. The second motor 21 drives the worm gear 20 to mesh with the worm wheel 19, driving the second rotating shaft 17 to rotate, causing the support member 18 to push the loading frame 12 to tilt. The self-locking characteristics of the worm wheel 19 and worm gear 20 can fix the loading frame 12 at any angle, preventing the workpiece from shifting due to gravity or vibration.

[0047] The unloading port 23 on the lifting platform 11 cooperates with the flipping action of the carrying frame 12, allowing the workpiece to fall through the unloading port 23 into the material frame 25 on the guide rail 24. The guide rail 24, through its low-friction sliding design, enables rapid replacement and transfer of the material frame 25, forming continuous operation. The protective shell 22 outside the second motor 21 isolates it from the corrosion of the ultrasonic cleaning fluid, extending the life of the components.

[0048] 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.
