Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment, specifically to an electroplating equipment for automotive trim parts with good safety features. Background Technology

[0002] Automotive trim electroplating equipment is used for electroplating the surface of automotive parts. It is commonly used for decorative and corrosion-resistant treatment of interior and exterior automotive trim. The electrolytic cell of the electroplating equipment is used to store the electroplating solution and deposit metal ions onto the surface of the parts through an electric current. There are two main electrodes in the electroplating equipment: an anode and a cathode. The anode is usually made of the metal material to be plated, while the cathode is the automotive trim itself. The current passes through the electrolyte to reduce the metal ions and deposit them onto the surface of the trim.

[0003] In the prior art, for example, Chinese Patent (Authorization Announcement No. CN222499453U) discloses an electroplating device for automobile parts production, which includes an electroplating machine. An electroplating tank is provided on one side of the upper surface of the electroplating machine. Above the electroplating tank is an anti-contact electroplating mechanism. The anti-contact electroplating mechanism includes two sealing covers, four hanging rods, an electroplating solution collection tank, a hot air dryer, and a lifting and changing mechanism. The four hanging rods are respectively fixedly installed on both sides inside the two sealing covers. The electroplating solution collection tank is located below the first sealing cover from left to right. The hot air dryer is fixedly installed in front of the electroplating solution collection tank. The lifting and changing mechanism allows the two sealing covers to move up and down synchronously and revolve around the center point between the two sealing covers. This electroplating device can prevent workers from directly contacting the electroplating solution during the electroplating process, thereby reducing the risk of injury to workers and improving equipment safety.

[0004] However, in the electroplating apparatus disclosed in the prior art, the two sealing caps revolve around the center point between them, causing the sealing caps to rotate and drive the hanging rod to rotate. This causes the rotational movement trajectory of the sealing caps to exceed the range of the electroplating solution collection tank. At this time, the hanging rod and the workpiece after electroplating carry excess electroplating solution. The electroplating solution is likely to drip onto the outside of the electroplating apparatus following the movement trajectory of the sealing caps, resulting in waste of the electroplating solution and affecting the working environment of the electroplating apparatus.

[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] See Figures 1-3As shown, an automotive trim electroplating apparatus with good safety features includes a base plate 1, an electroplating tank 101, a hot air dryer 102, and a collection tray 103. The electroplating tank 101 is connected to the base plate 1. The hot air dryer 102 is located on the side of the base plate 1 away from the electroplating tank 101. The collection tray 103 is provided between the electroplating tank 101 and the hot air dryer 102, and the collection tray 103 is connected to the base plate 1. The automotive trim electroplating apparatus also includes a hanger device for placing workpieces, a lifting device for controlling the vertical movement of the hanger device, and a linear displacement device for controlling the reciprocating movement of the hanger device between the electroplating tank 101 and the collection tray 103. The electroplating tank 101 is equipped with a first hanging device and a second hanging device above the collection tray 103. The first and second hanging devices have the same structure. A lifting device is located between the electroplating tank 101 and the collection tray 103 and is connected to the base plate 1. A linear displacement device is located below the lifting device. The offset translation device is located below the linear displacement device and is connected to the hanging device. The guide plate 2 is located on the side of the electroplating tank 101 near the collection tray 103.

[0029] Specifically, when processing the workpiece, the lifting device is first activated. The lifting device drives the first and second hanging devices to move upwards synchronously until the first hanging device is completely removed from the electroplating tank 101. At this point, the operator places the workpiece on the first hanging device. Subsequently, the lifting device is activated again, causing the first hanging device to move back into the electroplating tank 101, thereby bringing the workpiece into the electroplating tank 101 for electroplating operations.

[0030] During the electroplating process with the first hanging device carrying the workpiece, the operator places the remaining workpieces on the second hanging device. After the workpieces on the first hanging device are electroplated, the first hanging device is removed from the electroplating tank 101 again using a lifting device. At this time, a linear displacement device is activated, driving the first and second hanging devices closer together. During this process, the two hanging devices rotate 90 degrees each under the action of a misalignment and translation device, allowing them to move in parallel linear motion as they approach each other. Finally, the second hanging device moves above the electroplating tank 101, and the first hanging device moves above the collection tray 103.

[0031] Next, the lifting device moves the first and second hanging devices downwards synchronously, allowing the second hanging device to carry the workpiece into the electroplating tank 101 for electroplating, while the first hanging device carries the workpiece closer to the collection tray 103. At this time, the hot air dryer 102 is activated to dry the workpiece. When the first hanging device moves above the collection tray 103, it passes over the guide plate 2. Because the first hanging device rotates 90 degrees and moves in a straight line, the electroplating solution carried by the first hanging device and the workpiece will drip onto the surface of the guide plate 2. The guide plate 2 can guide excess electroplating solution into the electroplating tank 101 and the collection tray 103 respectively, preventing the electroplating solution carried by the hanging device and the workpiece from dripping onto the outside of the automotive trim electroplating device, thus helping to maintain the cleanliness of the automotive trim electroplating device workplace.

[0032] See Figures 1-4 As shown, the lifting device includes a hydraulic cylinder 3 and a support plate 301; the support plate 301 is located above the electroplating tank 101; there are two hydraulic cylinders 3, which are respectively connected to the base plate 1, and the output ends of the two hydraulic cylinders 3 are respectively connected to the lower side of the support plate 301.

[0033] Specifically, when it is necessary to remove the mounting bracket from the electroplating tank 101, the hydraulic cylinder 3 is activated. The output end of the hydraulic cylinder 3 pushes the support plate 301 upward, thereby moving the mounting bracket out of the electroplating tank 101. The automotive trim electroplating device is equipped with two hydraulic cylinders 3, which are respectively installed on both sides of the support plate 301. These two hydraulic cylinders 3 work together to ensure the stable movement of the support plate 301, and because of their arrangement on both sides of the support plate 301, they are less likely to interfere with the movement of the mounting bracket during operation.

[0034] See Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the linear displacement device includes a motor 4, a screw 401, a slider 402, a groove 403, and a synchronous transmission assembly 404 for simultaneously driving the screw 401 to rotate. The motor 4 is mounted on a support plate 301. The screw 401 is movably mounted on the support plate 301. The slider 402 is movably mounted on the screw 401 and is threadedly connected to the screw 401. The groove 403 is formed on the lower side of the support plate 301 for the slider 402 to pass through. The synchronous transmission assembly 404 is mounted on the support plate 301, with one side of its output end connected to one end of the screw 401 and the other side connected to the output end of the motor 4.

[0035] Specifically, the synchronous transmission assembly 404 includes three synchronous pulleys and a synchronous belt. The synchronous pulley in the middle of the synchronous belt is connected to the output end of the motor 4, and the synchronous pulleys at both ends of the synchronous belt are connected to two screws 401 respectively, with the synchronous pulleys and the synchronous belt in a meshing state. The threads of the two screws 401 are arranged in opposite directions. The cross-sectional dimensions of the slide groove 403 are precisely matched with the cross-sectional dimensions of the slider 402 to achieve a tight fit between the two.

[0036] When performing the position swapping operation between the first and second hanging devices, the lifting device is first activated to raise the hanging devices to a suitable height above the electroplating tank 101. Then, motor 4 is started, and its output drives the synchronous pulley in the middle of the synchronous belt to rotate. Based on the meshing transmission principle of the synchronous belt and synchronous pulley, the synchronous pulleys on both sides of the synchronous belt rotate synchronously, thereby driving the two connected screws 401 to rotate simultaneously. Because the cross-sectional dimensions of the slide groove 403 and the slider 402 are precisely matched, the slider 402 can only slide smoothly in a straight line within the slide groove 403, without rotating on its own as the screws 401 rotate. Furthermore, because the threads of the two screws 401 are opposite, during the rotation of the screws 401, the two sliders 402 can simultaneously move in opposite straight lines along the slide groove 403. During this period, the first hanging device gradually moves from above the electroplating tank 101 to above the collection tray 103, while the second hanging device moves from above the collection tray 103 to above the electroplating tank 101.

[0037] When motor 4 drives the synchronous pulley to rotate in the opposite direction, the first and second hanger devices can return to their initial positions. The screw 401 and slider 402 provide rigid support for the workpiece, ensuring that the hanger devices can stably move the workpiece. The hanger devices move linearly from the electroplating tank 101 to the collection tray 103, improving the workpiece displacement efficiency.

[0038] See Figures 3-6 , Figure 8 and Figure 9 As shown, the misalignment and translation device includes a gear 5 for rotating the hanger device, a first toothed plate 501 for driving the gear 5 to rotate, a first limiting mechanism for restricting the rotation of the gear 5, and a rectangular block 502 for controlling the vertical movement of the first limiting mechanism; the gear 5 is disposed inside the hanger device; the first toothed plate 501 is disposed on the lower side of the lifting device and meshes with the gear 5; the rectangular block 502 is disposed on the lower side of the linear displacement device and the lower side of the rectangular block 502 is rotatably connected to the upper side of the gear 5; the first limiting mechanism is disposed on the upper side of the gear 5.

[0039] Specifically, when the linear displacement device drives the two hanger devices to approach each other, gear 5 engages with the first toothed plate 501. Due to the meshing action between the first toothed plate 501 and gear 5, the first toothed plate 501 pushes gear 5 to rotate, thereby driving the hanger device to move. When gear 5 disengages from the first toothed plate 501, gear 5 rotates ninety degrees. At this time, the first limiting mechanism limits gear 5 to prevent gear 5 from rotating arbitrarily after disengaging from the first toothed plate 501, ensuring that the two gears 5 can stably drive the hanger devices to rotate separately, making the two hanger devices parallel to each other.

[0040] After the hanger device completes its rotation, the two hanger devices will not interfere with each other during the linear alignment process, ensuring that the hanger device can stably drive the workpiece to move.

[0041] See Figures 1-5 As shown, the hanging device includes a bracket 6 for assisting in the installation of the workpiece, a hook 601 for hanging the workpiece, and a second limiting mechanism for closing the opening of the hook 601; the upper end of the bracket 6 is connected to the gear 5; the hook 601 is connected to the bracket 6; and the second limiting mechanism is located at the end of the hook 601 away from the bracket 6.

[0042] Specifically, when installing the workpiece onto the hanger device, the workpiece is first hooked to the hook 601. Then, the second limiting mechanism is used to close the opening of the hook 601, thus firmly securing the workpiece to the hook 601.

[0043] Next, cable ties such as stainless steel cable ties and PTFE cable ties, which are unaffected by the electrolyte, are used to secure the workpiece to the bracket 6. This method enhances the stability of the workpiece on the hanger device, effectively preventing displacement of the workpiece during the movement of the hanger device driven by the lifting device, linear displacement device, and offset translation device, further strengthening the stability of the workpiece on the hanger device.

[0044] See Figure 8 and Figure 9 As shown, the first limiting mechanism includes a first toothed disc 7, which includes a rectangular groove, a second toothed disc 701, and an elastic reset member 702. The first toothed disc 7 has a rectangular groove inside, which slides and engages with a rectangular block 502. The second toothed disc 701 is connected to the gear 5 and engages with the first toothed disc 7. The elastic reset member 702 is sleeved on the outside of the rectangular block 502, and the lower end of the elastic reset member 702 is connected to the first toothed disc 7.

[0045] Specifically, the rectangular groove and rectangular block 502 are precisely matched in cross-sectional dimensions in their structural design. A spring is selected as the specific component for the elastic reset element 702.

[0046] When gear 5 drives the bracket device to rotate, gear 5 synchronously drives the second convex toothed disc 701 to rotate as well. During this process, the inclined surface of the convex toothed disc 701 interacts with the inclined surface of the convex toothed disc 701 and generates compression. Due to this compression, the first convex toothed disc 7 is displaced upward by force, which in turn applies pressure to the elastic reset member 702, causing the spring to contract and deform.

[0047] When gear 5 disengages from the first toothed plate 501 and stops rotating, the pressure of the first cam disc 7 on the elastic reset member 702 immediately disappears. At this time, the elastic reset member 702 begins to extend due to its own elastic recovery characteristics. During the extension process, the thrust generated by the elastic reset member 702 causes the first cam disc 7 to re-engage with the second cam disc 701. Furthermore, given the precise matching of the cross-sectional dimensions of the rectangular groove and the rectangular block 502, the deflection of the first cam disc 7 can be effectively suppressed whether it is in a moving or stationary state.

[0048] The above mechanism prevents gear 5 from rotating on its own without external driving force, ensuring that gear 5 remains stable after completing its rotation. This, in turn, ensures the stability of the hanger device after rotation, thanks to the coordinated action of the first limiting mechanism.

[0049] See Figure 4 and Figure 5 As shown, the second limiting mechanism includes a connecting plate 8 and a bolt 801 for limiting the connecting plate 8 and the hook 601 together; the connecting plate 8 is rotatably connected to the end of the hook 601 near the bracket 6; the bolt 801 is inserted into the end of the connecting plate 8 away from the bracket 6, and the end of the bolt 801 that passes through the connecting plate 8 is threadedly connected to the end of the hook 601 away from the bracket 6.

[0050] Specifically, when installing the workpiece and the hanger device, first rotate bolt 801 to disengage it from hook 601. At this time, the connecting plate 8 can be rotated to move it away from the opening of hook 601.

[0051] Next, hook the workpiece onto the hook 601. After hooking, rotate the connecting plate 8 again to close the opening of the hook 601. Then, remove the bolt 801 again, pass the bolt 801 through the connecting plate 8, and screw the bolt 801 onto the hook 601. The bolt 801 secures the connecting plate 8 and the hook 601 together, thus stably confining the workpiece between the connecting plate 8 and the hook 601.

[0052] See Figures 1-4 , Figure 6 and Figure 9As shown, the automotive trim electroplating device also includes a rotating device for rotating the drive bracket device when it approaches the hot air dryer 102. The rotating device includes a second toothed plate 9 for driving the gear 5 to rotate, a cylinder 901 for driving the second toothed plate 9 to move linearly reciprocatingly, a guide rail assembly 902 for maintaining the linear movement of the second toothed plate 9, a guide rod 903 for driving the first convex toothed disc 7 to move upward, and a guide plate 904 for abutting against the guide rod 903. The second toothed plate 9 is disposed on the side of the support plate 301 near the hot air dryer 102, and the second toothed plate 9 meshes with the gear 5. The cylinder 901 is disposed on the side of the support plate 301 near the second toothed plate 9, and the output end of the cylinder 901 is connected to one side of the second toothed plate 9. The guide rail assembly 902 is disposed between the second toothed plate 9 and the support plate 301. The guide rod 903 is vertically connected to the bottom edge of the support plate 301 near the second toothed plate 9. The guide plate 904 is connected to the first convex toothed disc 7.

[0053] Specifically, the guide rail assembly 902 consists of a rail and a guide block. The rail is connected to the lower side of the support plate 301, and the rail and the guide block are in a sliding connection state. At the same time, the guide block is connected to the second toothed plate 9, and the specifications of the rail and the guide block are compatible with each other.

[0054] When the hanging device carries the workpiece and approaches the hot air dryer 102 with the help of the linear displacement device, the guide plate 904 connected to the first cam toothed disc 7 gradually approaches the guide rod 903 and exerts a squeezing effect on the guide rod 903. At this time, the guide plate 904 is subjected to an upward force along the guide rod 903, which in turn drives the first cam toothed disc 7 to move upward, causing the first cam toothed disc 7 to disengage from the second cam toothed disc 701, thus preventing the two from interfering with the rotation of the gear 5.

[0055] In this state, cylinder 901 is activated, and the output end of cylinder 901 drives the second toothed plate 9 to perform linear reciprocating motion. Since the second toothed plate 9 is connected to the guide block, the guide block will move along the track, which ensures that the second toothed plate 9 is not prone to deviation during linear movement, thus enabling it to stably engage with gear 5.

[0056] The rotation of gear 5 is achieved through the meshing of the second toothed plate 9 and gear 5. When the output end of cylinder 901 extends outward, the second toothed plate 9 drives the hanging device to rotate 180 degrees clockwise; when the output end of cylinder 901 retracts inward, the second toothed plate 9 drives the hanging device to rotate 180 degrees counterclockwise. In this way, the hanging device can drive the workpiece to rotate in both directions, which facilitates the hot air dryer 102 to dry the workpiece evenly and thoroughly.

[0057] 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.
