Description

Technical Field

[0001] The present invention relates to the technical field of electroplating treatment of automobile parts, and in particular to an electroplating device for automobile exterior parts and a process thereof. Background Art

[0002] In the automotive manufacturing sector, electroplating of automotive exterior parts is a process that deposits metals or alloys on their surfaces through electrolysis. With advantages such as enhancing the aesthetics of exterior parts and strengthening corrosion resistance, it is of great significance to improving the overall quality and market competitiveness of automobiles. The Chinese patent publication number "CN220564768U" discloses an electroplating device for circular automotive parts. While the device uses a hydraulic rod to drive an immersion tank to place parts into the plating tank, the immersion tank and cover prevent parts from falling, thus reducing cost losses; This electroplating device has several drawbacks. From the perspective of plating solution utilization, since the device only uses a simple immersion method, the plating solution remains static during the electroplating process. As the electroplating reaction continues, the ion concentration will vary in local areas. For example, the concentration of metal ions near the anode increases due to continuous dissolution, while the concentration on the surface of the automotive exterior parts near the cathode gradually decreases due to continuous ion deposition. This leads to uneven composition of the plating solution. This unevenness prevents the plating solution from contacting the product under consistent reaction conditions, reducing the uniformity and quality stability of the electroplating. When it comes to contact between products and the plating solution, when a large number of automotive exterior parts need to be processed, products are often stacked due to limited space in the immersion tank. When stacked, part of the surface of the upper product can come into contact with the plating solution, while the contact area between the stacked contact surface and the surface of the lower product is greatly reduced. This leads to significant differences in the degree of plating between products, and even some areas cannot be plated, resulting in defects such as missing plating and too thin a coating. From the analysis of the product adjustment mechanism, the device lacks the function of effectively adjusting the product. In the actual electroplating process, the dynamic changes of the product help the electroplating liquid to fully cover all parts and ensure the comprehensiveness of the electroplating reaction. However, the product in this device can only be fixedly immersed in the electroplating liquid and cannot change its posture by flipping, moving, etc. It cannot solve the problem of difficulty in fully infiltrating the electroplating liquid due to the complex shape of the product, the presence of grooves or dead corners, etc., further aggravating the uneven electroplating condition. It can be seen that the existing technology has certain defects and shortcomings, and therefore needs to be improved and designed. Summary of the Invention

[0013] An electroplating process for automobile exterior parts comprises the following steps: Step 1: First, place the car bumper to be processed in the electroplating carrier frame. Use the magnetic suction function of the transport mechanism to move the carrier frame to the mounting plate and insert it into the side rails so that the bottom of the carrier frame is immersed in the electroplating tank. Step 2: Start the electroplating tank, turn on the first motor, drive the outer gear to drive the outer gear ring to rotate, so that the slip ring and the connecting ring move in a circle on the outer ring rail, drive the electroplating support frame to rotate, and perform the electroplating operation; Step 3: When the first motor is running, the connecting ring drives the electroplating carrier frame to slide in a ring shape in the electroplating tank, and the inner gear ring of the inner ring rail engages with the gear ring of the base ring to drive the side rail to drive the stirring plate and the spiral stirring blade to rotate, stirring the electroplating solution; Step 4: After the electroplating is completed, the electric push rod is started to push the electromagnet down to contact the magnetic plate.

[0014] Beneficial effects of the present invention: 1. During operation, the first motor drives the outer gear to rotate, which in turn drives the outer gear ring to rotate, thereby causing the slip ring and the connecting ring to rotate on the outer ring rail. The connecting ring drives the electroplating support frame to rotate. This rotation causes the automotive exterior parts inside the electroplating support frame to continuously change their position, enabling them to contact the electroplating solution in all directions, avoiding local insufficient contact, and promoting the electroplating solution to more evenly cover the surface of the exterior parts, thereby improving the uniformity and quality of electroplating. 2. When the electroplating carrier frame rotates, the inner gear ring on the inner ring rail meshes with the linkage gear ring on the base ring, and the inner gear ring drives the inner slip ring to rotate, thereby rotating the side rails. The mounting ring, stirring plate and spiral stirring blades at the bottom of the side rails rotate accordingly. The stirring plate moves in a circular shape along the inside of the electroplating tank while rotating, which can fully and evenly stir the electroplating solution in the electroplating tank, breaking the static state of the electroplating solution and making the ion distribution in the electroplating solution more uniform. The rotation of the spiral stirring blades causes the electroplating solution to roll up and down in the electroplating tank, further enhancing the fluidity of the electroplating solution, so that the effective ingredients in the electroplating solution can be more quickly transferred to the surface of the automotive exterior parts, accelerating the electroplating reaction, and improving the electroplating efficiency and effect. 3. While the electroplating carrier frame rotates, it also slides in a circular shape along the inside of the electroplating tank, while the stirring plate and spiral stirring blades rotate around the outside of the electroplating carrier frame, so that the automotive exterior parts in the electroplating carrier frame and the surrounding electroplating liquid are always in a dynamic relative motion state. This relative motion increases the friction and impact force between the electroplating liquid and the exterior parts, helps to remove bubbles and impurities that may exist on the surface of the exterior parts, enables the electroplating liquid to better contact the surface of the exterior parts, and improves the adhesion and quality of the electroplating. At the same time, the dynamic electroplating liquid environment is also conducive to timely replenishing the consumed electroplating ions, maintaining the uniformity of the electroplating liquid composition, and further improving the electroplating effect.

The driving mechanism 4 includes an outer ring rail 41 and a driving assembly 42. The outer ring rail 41 is fixedly installed on the top of the electroplating tank 5. The inner part of the outer ring rail 41 is slidably connected to the outer slip ring 43. The outer side of the outer slip ring 43 is fixedly installed with a connecting ring 44. The carrying mechanism 3 is arranged in a ring shape with equal spacing and fixedly connected to the inner side of the connecting ring 44. The driving assembly 42 is fixedly connected to the side of the outer surface of the electroplating tank 5 away from the conveying mechanism 7. During the application of this equipment, a PLC control system and a displacement sensor can be correspondingly equipped for detection to facilitate its automatic control up and down When using the electroplating equipment for automobile exterior parts, the automobile exterior parts to be electroplated are placed in the electroplating supporting mesh frame 33 of the supporting mechanism 3, the equipment is started, the driving component 42 starts to work, driving the outer sliding ring 43 in the outer ring rail 41 to slide, and the outer sliding ring 43 drives the connecting ring 44 to make a circular motion on the top of the electroplating tank 5, thereby causing the supporting mechanism 3 fixed at equal intervals on the inner side of the connecting ring 44 to rotate accordingly, and the electroplating supporting mesh frame 33 on the supporting mechanism 3 and the internal exterior parts also rotate synchronously, fully contacting the electroplating solution in the electroplating tank 5, and performing During the electroplating operation, when the carrying mechanism 3 rotates, the linkage mechanism 6 is driven to operate through the transmission connection. The stirring plate 322, the spiral stirring blade 323 and other components of the linkage mechanism 6 stir the electroplating liquid in the electroplating tank 5 in all directions, causing the electroplating liquid to roll up and down, thereby improving the contact uniformity between the electroplating liquid and the exterior parts. When the electroplating is completed, the PLC control system controls the movement of the conveying mechanism 7 outside the electroplating tank 5 according to the position signal detected by the displacement sensor, and the electric push rod 76 pushes the electromagnet 77 downward to contact the magnetic plate 7 on the top of the electroplating carrying frame 33. 2 contact, the electromagnet 77 is energized to adsorb and fix the screen frame, the electric push rod 76 is pulled up, and then the second motor 73 drives the bracket 74 to rotate, and the electroplating carrying screen frame 33 is transported to the outer conveyor belt of the electroplating tank 5 for unloading. Subsequently, the transport mechanism 7 transports the new electroplating carrying screen frame 33 equipped with unplated exterior parts into the electroplating tank 5, and repeats the above process to realize continuous automated electroplating production. The electroplating tank 5 is a prior art, and its specific interior has basic electroplating tank 5 functions such as anode, cathode, etc. The electroplating tank 5 is a prior art means, so it will not be described here.

[0019] Combine Figure 1-Figure 7 As shown, the driving assembly 42 includes a fixed plate body 421 and an outer gear ring 422. The fixed plate body 421 is fixedly installed on the side of the electroplating pool 5 away from the conveying mechanism 7. The bottom outer side of the fixed plate body 421 is fixedly connected to a first motor 423. The output end of the first motor 423 is fixedly connected to an outer gear 424. The outer gear 424 and the outer gear ring 422 are meshed and connected.

[0020] The technical solution in the above-mentioned embodiment of the present application, during the use of this equipment, when the automobile exterior trim electroplating equipment is running, the first motor 423 serves as the power source of the drive assembly 42, and is installed on the outer side of the bottom of the fixed plate 421. When the first motor 423 is started, its output end drives the outer gear 424 to rotate at a high speed. Since the outer gear 424 and the outer gear ring 422 are engaged with each other, the rotation of the outer gear 424 transmits power to the outer gear ring 422, causing the outer gear ring 422 to start rotating. The outer gear ring 422 is connected to the outer slip ring 43, and its rotation drives the outer slip ring 43 inside the outer ring rail 41 to slide. The outer slip ring 43 is connected to the connecting ring 44, so that the connecting ring 44 makes a circular motion on the top of the electroplating tank 5. The supporting mechanism 3 is fixed at equal intervals on the inner side of the connecting ring 44, so that the circular motion of the connecting ring 44 eventually drives the supporting mechanism 3 to rotate, so that the automobile exterior trim in the electroplating supporting mesh frame 33 on the supporting mechanism 3 rotates accordingly, achieving full contact with the electroplating liquid in the electroplating tank 5, and providing the necessary motion conditions for the electroplating operation. Example 2

[0021] Combine Figure 4-Figure 8 As shown, the supporting mechanism 3 includes an inner ring rail 31, which is arranged in a ring shape at equal intervals and fixedly connected to the inner side of the connecting ring 44. The inner side of the inner ring rail 31 is movably connected with a mounting assembly 34. The interior of the inner ring rail 31 is installed with an electroplating supporting mesh frame 33 through the mounting assembly 34. The bottom of the mounting assembly 34 is installed with a stirring assembly 32. The mounting assembly 34 includes an inner slip ring 341, which is rotatably connected to the interior of the inner ring rail 31. Side rails 342 are fixedly connected on both sides of the inner slip ring 341. A mounting plate 343 is inserted into the interior of the side rail 342. The electroplating supporting mesh frame 33 is fixedly connected to the inner side of the mounting plate 343.

[0022] According to the technical solution in the above-mentioned embodiment of the present application, during use, when the driving component 42 drives the connecting ring 44 to perform a circular motion on the top of the electroplating tank 5, the inner ring rail 31 fixed on the inner side of the connecting ring 44 moves accordingly, and the inner sliding ring 341 rotatably connected inside the inner ring rail 31 will also rotate along the trajectory of the inner ring rail 31 due to the cooperation relationship with the inner ring rail 31. The side rails 342 fixed on both sides of the inner sliding ring 341 move synchronously with the inner sliding ring 341, driving the mounting plate 343 inserted into the side rails 342, and the electroplating support frame 33 fixedly connected to the inner side of the mounting plate 343 also rotates with the mounting plate 343, so that the automotive exterior parts in the electroplating support frame 33 rotate in the electroplating tank 5 and are fully in contact with the electroplating solution. At the same time, the stirring component 32 at the bottom of the mounting component 34 is driven to work during the movement of the mounting component 34 to stir the electroplating solution in the electroplating tank 5, further promoting uniform contact between the electroplating solution and the exterior parts, and improving the electroplating effect.

[0023] Combine Figure 3-Figure 7As shown, the stirring assembly 32 includes a mounting ring 321, which is fixedly connected to the bottom of the side rail 342, and the bottom of the mounting ring 321 is fixedly connected with stirring plates 322 arranged in a ring at equal intervals, and the stirring plates 322 are arranged in a ring at equal intervals and arranged on the outside of the electroplating supporting mesh frame 33. The stirring assembly 32 also includes a spiral stirring blade 323, which is fixedly installed on the inner side of the stirring plate 322, and the stirring plate 322 is L-shaped as a whole. The linkage mechanism 6 includes a mounting pipe rack 61 and an inner gear ring 62. The mounting pipe rack 61 is fixedly installed in the middle of the electroplating tank 5, and a base ring 63 is fixedly installed on the top of the mounting pipe rack 61. A linkage gear ring 64 is fixedly installed on the outside of the base ring 63, and the inner gear ring 62 is fixedly connected to the top of the inner slip ring 341. The linkage gear ring 64 and the inner gear ring 62 are meshed.

[0024] According to the technical solution in the above-mentioned embodiment of the present application, during the application of the present device, when the inner slip ring 341 rotates in the inner ring rail 31, the side rail 342 fixedly connected thereto moves accordingly, driving the mounting ring 321 at the bottom to rotate, thereby causing the L-shaped stirring plate 322 at the bottom of the mounting ring 321 to make a circular motion around the outside of the electroplating support mesh frame 33. The stirring plate 322 stirs the electroplating solution in all directions through rotation. At the same time, the spiral stirring blade 323 fixed on the inner side of the stirring plate 322 also rotates, causing the electroplating solution to roll up and down in the electroplating tank 5. , enhancing the fluidity of the electroplating solution. During this process, the inner gear ring 62 on the top of the inner slip ring 341 rotates with the inner slip ring 341. Since the inner gear ring 62 is engaged with the linkage gear ring 64 on the outer side of the base ring 63 on the top of the mounting pipe frame 61, the inner gear ring 62 interacts with the linkage gear ring 64 when rotating, ensuring the stability and continuity of the rotation of the inner slip ring 341, further ensuring that the stirring component 32 continuously and efficiently stirs the electroplating solution, so that the electroplating solution and the automotive exterior parts in the electroplating supporting mesh frame 33 are more evenly contacted, thereby improving the quality and efficiency of electroplating. Example 3

[0025] Combine Figure 1-Figure 3 As shown, the conveying mechanism 7 includes a mounting base 71 and a magnetic plate 72. Two mounting bases 71 are provided. The mounting bases 71 are fixedly mounted at both ends of the electroplating pool 5 away from the fixed plate body 421. A second motor 73 is fixedly mounted on the bottom of the mounting base 71. The output end of the second motor 73 passes through the mounting base 71 and is fixedly mounted with a bracket 74. A top plate 75 is fixedly mounted on the top of the bracket 74.

A drain pipe 9 is fixedly mounted on the output end of the drain valve 8.

[0026] According to the technical solution in the embodiment of the present application, during the application of the present equipment, when the electroplating operation is completed, the PLC control system controls the second motor 73 located at the bottom of the base plate 71 at both ends of the electroplating tank 5 away from the fixed plate 421 to start, and the output end of the second motor 73 drives the bracket 74 to rotate, and the electric push rod 76 and the electromagnet 77 installed at the inner end of the top plate 75 of the bracket 74 are rotated to the appropriate position directly above the electroplating support frame 33. Subsequently, the electric push rod 76 is started, and its output end pushes the electromagnet 77 to move downward until the electromagnet 77 contacts the magnetic plate 72 in the middle of the top of the electroplating support frame 33, and the electromagnet 77 is energized to generate magnetic force to attract the magnetic plate 72. 2. Firmly fix the electroplating support frame 33. Then, the electric push rod 76 contracts and lifts up to pull the electroplating support frame 33 out of the electroplating tank 5. Then, the second motor 73 runs again, driving the bracket 74 to rotate, and the electromagnet 77 adsorbing the electroplating support frame 33 is transferred to the specified position outside the electroplating tank 5. The electromagnet 77 is powered off to release the electroplating support frame 33 to complete the unloading. In addition, when the electroplating solution needs to be replaced, open the drain valve 8 in the middle of the bottom of the electroplating tank 5, and the electroplating solution flows into the drain pipe 9 through the drain valve 8 to be discharged, so as to facilitate the subsequent addition of new electroplating solution.

[0027] An electroplating process for automobile exterior parts comprises the following steps: Step 1: First, place the car bumper to be processed in the electroplating carrier frame 33. Use the magnetic suction function of the transport mechanism 7 to transport the carrier frame to the mounting plate 343 and insert it into the side rails 342 so that the bottom of the carrier frame is immersed in the electroplating tank 5. Step 2: Start the electroplating cell 5, turn on the first motor 423, drive the outer gear 424 to drive the outer gear ring 422 to rotate, so that the slip ring and the connecting ring 44 move in a circle on the outer ring rail 41, drive the electroplating support frame 33 to rotate, and perform the electroplating operation; Step 3: When the first motor 423 is running, the connecting ring 44 drives the electroplating support frame 33 to slide in an annular shape in the electroplating tank 5. The inner gear ring 62 of the inner ring rail 31 and the gear ring 64 of the base ring 63 are meshed and driven, so that the side rail 342 drives the stirring plate 322 and the spiral stirring blade 323 to rotate, stirring the electroplating solution; Step 4: After the electroplating is completed, the electric push rod 76 is started to push the electromagnet 77 downward to contact the magnetic plate 72. The electromagnet 77 is energized to adsorb and fix the electroplating support frame 33. The electric push rod 76 is pulled up to lift the electroplating support frame 33. Step 5: Start the second motor 73 to drive the bracket 74 to rotate, and move the electroplating support frame 33 from above the electroplating tank 5 to the outer conveyor belt to complete the unloading; Step 6: Using the second motor 73, the electric push rod 76 and the electromagnet 77 to cooperate, the new unplated automobile bumper carrying frame is transported into the electroplating tank 5 to start a new round of operation.

[0028] The operating principle and advantages of the present invention are as follows: during the electroplating process of the present invention, the driving mechanism 4 cooperates with the supporting mechanism 3, so that in actual use, the automobile exterior parts to be electroplated can be placed in the electroplating supporting frame 33 first, and the magnetic suction function of the transporting mechanism 7 is used to transport the electroplating supporting frame 33 to the mounting plate 343, and the mounting plate 343 is inserted into the side rail 342, so that the electroplating supporting frame 33 with the exterior parts is placed on the inner side of the side rail 342. At this time, the bottom of the electroplating supporting frame 33 extends into the electroplating tank 5, and the electroplating can be started. The electroplating pool 5 is driven to carry out the electroplating operation. During the electroplating process, the first motor 423 is started, which drives the outer gear 424 to rotate. The outer gear 424 drives the outer gear ring 422 to rotate, thereby causing the slip ring and the connecting ring 44 to perform a circular motion on the outer ring rail 41. The rotation of the connecting ring 44 drives the inner side supporting mechanism 3 to rotate synchronously, causing the electroplating supporting mesh frame 33 to rotate accordingly. This rotation promotes more complete and uniform contact between the automotive exterior parts in the mesh frame and the electroplating solution, effectively improving the electroplating efficiency and quality, and ensuring that the electroplating layer evenly covers the surface of the exterior parts; During the electroplating process, the coordinated design of the linkage mechanism 6 and the supporting mechanism 3 can further improve the electroplating effect. During use, when the first motor 423 drives the electroplating supporting mesh frame 33 to rotate, the mesh frame is in full contact with the electroplating liquid. At the same time, the rotation of the connecting ring 44 causes the electroplating supporting mesh frame 33 to slide in a ring shape in the electroplating tank 5. During this process, the inner gear ring 62 on the inner ring rail 31 and the linkage gear ring 64 on the base ring 63 engage with each other for transmission. Since the base ring 63 is fixed, the inner gear ring 62 rotates with the movement of the outer slip ring 43, thereby driving the inner slip ring 341 in the inner ring rail 31 to rotate, and the rotation of the inner slip ring 341 drives the side rail. 342 rotates, and the side rails 342 drive the bottom mounting ring 321, the stirring plate 322 and the spiral stirring blade 323 to rotate. The stirring plate 322 moves in a circular shape along the electroplating tank 5 while rotating itself, stirring the electroplating liquid in the electroplating tank 5 in all directions. In addition, when the stirring plate 322 rotates, it drives the spiral stirring blade 323 to rotate, causing the electroplating liquid to roll up and down in the electroplating tank 5. This design not only puts the electroplating support frame 33 and the automotive exterior parts inside it in a dynamic working state, but also realizes the efficient flow of the electroplating liquid, further strengthens the uniform contact between the electroplating liquid and the exterior parts, significantly improves the electroplating effect, and ensures the electroplating quality of the automotive exterior parts; This device adopts the setting of a conveying mechanism 7, which can further improve the convenience and safety of the use of this device. During the operation of the equipment, the electric push rod 76 is started, which pushes the electromagnet 77 to move downward until the electromagnet 77 contacts the magnetic plate 72 on the top of the electroplating support mesh frame 33. At this time, the electromagnet 77 is started and energized, and the magnetic plate 72 is adsorbed by electromagnetic attraction, thereby fixing the electroplating support mesh frame 33. Subsequently, the electric push rod 76 moves again to pull the adsorbed electroplating support mesh frame 33 upward. When the mesh frame is lifted, the second motor 73 is started, which drives the top bracket 74 to rotate, and the electroplating support mesh frame 33 is moved out from above the electroplating tank 5 to the outside, and a conveyor belt is provided on the outside of the electroplating tank 5. , can directly receive the electroplated screen frame and internal and external decorative parts to realize automatic unloading. At the same time, through the coordinated operation of the second motor 73, the electric push rod 76 and the electromagnet 77, the unplated screen frame and external decorative parts can be automatically transported to the electroplating tank 5 to complete automatic loading. The design of the two sets of transporting mechanisms 7 enables the equipment to perform loading and unloading operations at the same time. One group is responsible for sending the external decorative parts to be electroplated into the electroplating tank 5, and the other group takes out the electroplated external decorative parts, realizing a continuous and rapid electroplating production process. This not only avoids the risk of human injury caused by manual operation of the electroplating solution, but also significantly improves the efficiency of electroplating production of automotive exterior decorative parts, so that the equipment can meet the needs of large-scale and efficient production.
