Description

Technical Field

[0001] This invention relates to the field of electrophoresis equipment technology, and more specifically to an electrophoresis hanger for automotive parts. Background Technology

[0002] Electrophoretic coating is a standard process for automotive corrosion protection. During the electrophoretic process, a lifting device is needed to lift the automotive parts into the coating tank for electrophoretic coating. The electrophoretic lifting device is an important tooling equipment in the electrophoretic process.

[0003] Existing electrophoresis lifting devices have simple structures and can meet single lifting requirements, but they generally have the following problems: 1. The electrophoresis hanger mainly consists of a movable frame and a hook frame. The movable frame is a moving part on the electrophoresis coating tank and has hanging rings welded on it for attaching the hook frame. The hook frame is used to hang a batch of automotive parts. During loading and unloading operations, it is usually necessary to manually lift the hook frame into the movable frame or remove it from it. This requires a lot of manpower and is also prone to human error that causes parts to scatter, resulting in low loading and unloading efficiency. 2. When performing electrophoresis on parts with complex shapes, such as parts with internal cavities, air bubbles may remain inside the cavity when the parts are immersed in the electrophoretic coating tank, which will affect the quality of electrophoretic coating. During the electrophoretic coating process, air bubbles may also remain on the surface of the workpiece, which will also affect the quality of electrophoresis. 3. After electrophoresis, for parts with cavities, "liquid pooling" is easily formed in the cavities. The residual liquid needs extra time to drain in order to avoid contamination during transportation, which greatly affects the overall efficiency.

[0004] Therefore, this invention proposes an electrophoresis lifting device for automotive parts. Summary of the Invention

[0005] The purpose of this invention is to provide an electrophoresis hanger for automotive parts in order to solve the problems mentioned above in the background art.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: An electrophoresis lifting device for automotive parts, comprising: A rectangular hanging frame, with a movable frame installed on the top of the rectangular hanging frame; The loading and unloading structure includes two clamping horizontal rails fixedly connected to the top of the rectangular lifting frame. The two clamping horizontal rails are arranged in parallel and each side is constructed with a strip-shaped through groove. Multiple limiting grooves are arrayed in the strip-shaped through grooves along their length direction. A lifting plate is vertically slidably installed at the bottom of the clamping horizontal rail. A suspension frame, in multiple quantities, is installed between two clamping horizontal rails. The suspension frame includes a hanging rod installed between two limiting grooves. A rotating disk is connected to the bottom of the hanging rod. A horizontal frame is fixedly connected to the bottom of the rotating end of the rotating disk. L-shaped vertical plates are fixedly connected to both ends of the horizontal frame. The two L-shaped vertical plates are arranged in parallel and have multiple hook grooves arrayed along their length on opposite sides. Multiple support frames are installed between the two L-shaped vertical plates through the hook grooves. The lifting and vibration mechanism is located between the rotating disk and the hanging rod and is used to drive the rotating disk to move up and down.

[0007] Furthermore, the clamping rail includes a U-shaped strip with a horizontally set opening. The bottom side of the opening end of the U-shaped strip has a protrusion. The limiting groove is formed on the protrusion. A pressure plate located directly above the limiting groove is vertically slidably installed inside the top of the U-shaped strip. A knob threaded through the U-shaped strip is rotatably installed on the upper side of the pressure plate. Guide posts that slide through the U-shaped strip are fixedly connected to both ends of the pressure plate.

[0008] Furthermore, the lifting plate includes a support plate that is vertically slidably installed at the bottom of the U-shaped strip. A screw threaded through the U-shaped strip is rotatably installed on the bottom side of the support plate, and sliding columns that slide through the U-shaped strip are fixedly connected to both ends of the support plate.

[0009] Furthermore, each of the two L-shaped vertical plates is fixedly connected to a support rod at its bottom end, and a connecting rod is constructed between the two support rods.

[0010] Furthermore, the support frame includes a horizontally arranged column, with positioning vertical plates inserted into hook grooves at both ends of the column. Multiple extension rods perpendicular to the column are arranged in an array along its length direction. Triangular hooks are arranged at both ends of the extension rods, with two triangular hooks tilted upwards and facing opposite directions.

[0011] Furthermore, the rotating disk includes a circular frame, within which a rotating column is rotatably mounted via a bearing, extending through its bottom. The bottom of the rotating column has a connecting plate connected to a crossbar. A lever is fixedly connected to one end of the rotating column within the circular frame. A spacer bar is constructed within the circular frame, positioned opposite to the lever. An air inlet pipe and an air outlet pipe, communicating with the interior of the circular frame, are constructed at the top of the frame. The air inlet pipe and air outlet pipe are respectively located on both sides of the spacer bar. A one-way valve is installed within both the air inlet pipe and the air outlet pipe.

[0012] Furthermore, the lifting vibration mechanism includes two cylindrical columns fixedly connected to the top of the circular frame. Each of the two cylindrical columns has a sliding rod slidably inserted at its top and connected to a hanging rod. The bottom of each sliding rod is fixedly connected to a piston block slidably installed inside the cylindrical column. A vibrating element for driving the sliding rod to move up and down is installed on the cylindrical column.

[0013] Furthermore, the vibrating element includes a tension spring fixedly connected between the piston block and the top of the inner cylinder. An inflation pipe and an exhaust pipe are respectively constructed on both sides of the cylinder. A sealing block is inserted into each of the two exhaust pipes. A pull handle is connected between the two sealing blocks. A one-way valve is installed in the inflation pipe.

[0014] Furthermore, both the one-way valve one and the one-way valve two include an annular plate and an annular block connected in the air inlet pipe, the air outlet pipe, and the air filling pipe. A semi-circular groove is constructed on the side of the annular block facing the annular plate, and a sealing ball that abuts against the semi-circular groove is connected to the annular plate by a support spring.

[0015] Furthermore, it also includes a driving component for driving the rotating column to rotate and the piston block to move. The driving component includes an insulating frame fixedly connected to the side of the moving frame. An air pump is fixedly connected to the insulating frame. A vent pipe is connected between one of the air inlet pipes and the air outlet pipe on two adjacent rotating disks. An inflation hose is connected to the other air inlet pipe. A diversion hose is connected to the inflation pipe. The other ends of the diversion hose and the inflation hose are both connected to the air pump through a switching valve.

[0016] The beneficial effects of this invention are as follows: 1. This invention sets up a clamping horizontal rail inside a rectangular hanging frame, and uses a lifting plate to lift and cover the limiting groove. This allows the suspension frame to enter or disengage from the clamping horizontal rail simply by moving horizontally during installation and disassembly, without the need for manual lifting. This saves a lot of manpower, increases loading and unloading efficiency, and avoids accidents caused by personnel losing strength, thus improving safety.

[0017] 2. By setting a rotating disk between the hanging rod and the crossbar, the present invention can slowly rotate the parts at regular intervals during the electrophoretic coating process, so that the air bubbles trapped on the parts can be removed, thus ensuring the quality of the electrophoretic coating.

[0018] 3. By setting a lifting vibration mechanism between the rotating disk and the hanging rod, the present invention can vibrate the parts up and down when the parts are immersed in the electrophoresis tank, so as to expel the air bubbles in the inner cavity of the parts and ensure the quality of electrophoretic coating. After the electrophoretic coating is completed, the parts can be vibrated when they are above the electrophoresis tank, so that the residual liquid in the cavity can flow out quickly, so as to facilitate the rapid entry into the next process and improve the overall efficiency.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, an embodiment of the present invention provides an electrophoresis hanger for automotive parts, comprising: A rectangular lifting frame 1 is provided, and a movable frame 101 is installed on the top of the rectangular lifting frame 1. It should be noted that this device is installed on the upper side of the existing electrophoresis coating tank and is lifted and moved by a gantry crane. The movable frame 101 is used as a connecting component so that the whole device can move on the electrophoresis tank. The loading and unloading structure 2 includes two clamping horizontal rails 201 fixedly connected to the top of the rectangular lifting frame 1. The two clamping horizontal rails 201 are arranged in parallel and each side is constructed with a strip-shaped through groove 202. The two ends of the strip-shaped through groove 202 are loading and unloading ports. Multiple limiting grooves 203 are arrayed in the strip-shaped through groove 202 along its length direction. The multiple limiting grooves 203 can be set to adjust the installation position and number of installations as needed, increasing flexibility. A lifting plate 204 is vertically slidably installed at the bottom of the clamping horizontal rail 201. Multiple suspension brackets 3 are mounted between two clamping horizontal rails 201. Each suspension bracket 3 includes a hanging rod 301 mounted between two limiting slots 203. A rotating disk 302 is connected to the bottom of the hanging rod 301. A horizontal frame 303 is fixedly connected to the bottom of the rotating end of the rotating disk 302. L-shaped vertical plates 304 are fixedly connected to both ends of the horizontal frame 303. The two L-shaped vertical plates 304 are arranged parallel to each other, and multiple hook slots 305 are arrayed along their length on opposite sides. Multiple support frames 4 are mounted between the two L-shaped vertical plates 304 through the hook slots 305. It should be noted that the suspension bracket 3 is entirely mounted in the strip-shaped through-slot 202 within the clamping horizontal rails 201 via the hanging rod 301 and positioned by the limiting slots 203. In traditional installation, the suspension bracket 3 is typically first placed on a mobile frame, and then the mobile frame is pushed to the side of the rectangular hanging frame 1. Manually lifting the suspension frame 3 and attaching it to the rectangular lifting frame 1 requires a lot of manpower and carries the risk of accidental loss of force, causing the workpiece to fall. However, the loading and unloading structure 2 of this device can be used not only on the rectangular lifting frame 1 but also on the mobile frame. When installing the suspension frame 3, simply push the mobile frame next to the rectangular lifting frame 1 and align it with the loading and unloading port of the clamping rail 201. Then, the lifting plate 204 moves up to cover the limiting groove 203, creating a flat surface at the bottom of the strip groove 202. Personnel can then horizontally push the hanging rod 301 into it. Afterward, the lifting plate 204 descends, and the hanging rod 301 automatically falls into the limiting groove 203 to complete the installation. During disassembly, the lifting plate 204 can also be moved up to push the hanging rod 301 out, and then it can be horizontally pushed into the mobile frame, saving a lot of manpower and ensuring loading and unloading safety. The lifting and vibration mechanism 5 is set between the rotating disk 302 and the hanging rod 301 and is used to drive the rotating disk 302 to move up and down. It should also be noted that after immersing the automotive parts in the electrophoresis tank, they need to be left to stand for a certain period of time to allow the air bubbles to detach before the power is applied. For parts with complex structures, the lifting and vibration mechanism 5 in this device can be used to move the entire part up and down in the electrophoresis tank, thereby quickly expelling any residual air bubbles and reducing the possibility of air bubble retention, ensuring the quality of subsequent electrophoretic coating. During electrophoresis, air bubbles may also accumulate on the surface of the workpiece. The rotating disk 302 can be used to periodically rotate the crossbeam 303 and the parts in the electrophoresis tank to remove the air bubbles and ensure the quality of electrophoretic coating. After electrophoresis is completed, the parts are lifted out of the electrophoresis tank, and the liquid remaining in their cavities needs to be drained over time. At this time, the lifting and vibration mechanism 5 can be used to drive the parts to vibrate up and down, allowing the residual liquid in the cavity to flow out quickly, so as to quickly enter the next process and improve overall efficiency.

[0023] like Figures 2-3 As shown, the specific structure of the clamping horizontal rail 201 of the present invention is disclosed. The clamping horizontal rail 201 includes a U-shaped strip 2011 with a horizontally arranged opening. A protrusion 2012 is constructed on the bottom side of the opening end of the U-shaped strip 2011. A limiting groove 203 is constructed on the protrusion 2012. A pressure plate 2013 located directly above the limiting groove 203 is vertically and slidably installed on the top of the U-shaped strip 2011. A knob 2014 threaded through the U-shaped strip 2011 is rotatably installed on the upper side of the pressure plate 2013. Guide posts 2015 that slide through the U-shaped strip 2011 are fixedly connected to both ends of the pressure plate 2013. It should be noted that the top of the U-shaped strip 2011 has a... The pressure plate 2013 is normally located within the groove. When the upper surface of the lifting plate 204 moves past the protrusion 2012, a planar cavity is formed between the lifting plate 204 and the pressure plate 2013, facilitating the translation and pushing of the hanging rod 301. When the hanging rod 301 is pushed into the U-shaped strip 2011, the lifting plate 204 descends, and the hanging rod 301 enters the limiting groove 203 for positioning. At this time, the knob 2014 can be rotated to make it threadedly engage with the U-shaped strip 2011, thereby driving the pressure plate 2013 to descend until it presses against the hanging rod 301, thus further fixing the position of the hanging rod 301, preventing it from easily detaching, and increasing safety.

[0024] like Figures 2-3As shown, the specific structure of the lifting plate 204 of the present invention is disclosed. The lifting plate 204 includes a support plate 2041 that is vertically slidably installed at the bottom of the U-shaped strip 2011. A screw 2042 threaded through the U-shaped strip 2011 is rotatably installed on the bottom side of the support plate 2041. Sliding columns 2043 that slide through the U-shaped strip 2011 are fixedly connected to both ends of the support plate 2041. When it is necessary to install or remove the hanging rod 301, the screw 2042 can be rotated to make it threadedly engage with the U-shaped strip 2011, thereby driving the support plate 2041 to rise or fall, so as to facilitate the subsequent moving of the hanging rod 301 in or out. The lifting force is converted into the spiral rotation force, which can effectively reduce manpower and make it easier to lift the hanging rod 301 as a whole, so as to facilitate the subsequent horizontal disassembly operation and increase convenience.

[0025] like Figure 4 As shown, the connection structure at the bottom of the crossbeam 303 of the present invention is disclosed. The bottom ends of the two L-shaped vertical plates 304 are fixedly connected to support rods 3041, and a connecting rod 3042 is constructed between the two support rods 3041. It should be noted that both the support rods 3041 and the connecting rod 3042 are cylindrical in shape to facilitate the detachment of the solution. The support rods 3041 can increase the contact area with the bottom surface when the suspension frame 3 is placed on the ground, thereby improving the support stability. The connecting rods 3042 installed between the support rods 3041 can form a rectangular frame with the crossbeam 303 and the two L-shaped vertical plates 304, increasing the stability of the structure and improving the service life.

[0026] like Figure 5 The specific structure of the support frame 4 of the present invention is disclosed. The support frame 4 includes a horizontally arranged column 401. Both ends of the column 401 are provided with positioning vertical plates 402 inserted into hook grooves 305. Multiple extension rods 403 perpendicular to the column 401 are arranged in an array along its length direction. Both ends of the extension rods 403 are provided with triangular hooks 404. The two triangular hooks 404 are inclined upward and oriented in opposite directions. The triangular hooks 404 are specifically triangular plate structures that can be inserted into the holes of the parts and use their edges to contact the holes, reducing the contact area for electrophoretic coating. The support frame 4 is detachably connected through the positioning vertical plates 402 and the hook grooves 305, so that the support frame 4 can be disassembled individually to form a modular structure, which facilitates the batch installation and disassembly of parts and increases the flexibility of the device.

[0027] like Figures 6-8The specific structure of the rotating disk 302 of the present invention is disclosed. The rotating disk 302 includes a circular frame 3021. A rotating column 3022, which is rotatably mounted inside the circular frame 3021 through a bearing, extends through the bottom of the circular frame 3021. A connecting plate 3023, which is connected to a cross frame 303, is constructed at the bottom of the rotating column 3022. A toggle lever 3024 is fixedly connected to one end of the rotating column 3022 inside the circular frame 3021. A spacer bar 3025, which is opposite to the toggle lever 3024, is constructed inside the circular frame 3021. An air inlet pipe 3026 and an air outlet pipe 3027, which are connected to the top of the circular frame 3021, are constructed at the top of the circular frame 3021. The air inlet pipe 3026 and the air outlet pipe 3027 are respectively arranged on both sides of the spacer bar 3025. A one-way valve 6 is installed in both the air inlet pipe 3026 and the air outlet pipe 3027. The air passage direction of the one-way valve 6 in the air inlet pipe 3026 faces inward toward the circular frame 3021. The ventilation direction of the vent pipe 3027 faces outward from the circular frame 3021. It should be noted that the circular frame 3021 has an annular cavity arranged around the rotating column 3022. The spacer rod 3025 is arranged in the annular cavity and located on one side of the rotating column 3022. The actuating rod 3024 is slidably installed in the annular cavity around the circumference of the rotating column 3022 and located on the other side of the rotating column 3022. When air enters through the vent pipe 3026, the air pressure in the annular cavity on the side of the actuating rod 3024 facing the vent pipe 3026 will increase, thereby squeezing and moving the actuating rod 3024 towards the annular cavity on the other side. The gas in the annular cavity on the other side will be discharged through the vent pipe 3027. In this way, the actuating rod 3024 drives the rotating column 3022 to rotate, thereby driving the cross frame 303 and automotive parts to rotate in the electrophoresis tank, which facilitates the removal of air bubbles and ensures the quality of electrophoretic coating.

[0028] like Figures 9-10 The specific structure of the lifting vibration mechanism 5 of the present invention is disclosed. The lifting vibration mechanism 5 includes two cylindrical tubes 501 fixedly connected to the top of the circular frame 3021. Each cylindrical tube 501 has a sliding rod 502 slidably inserted at its top and connected to the hanging rod 301. The bottom of each sliding rod 502 is fixedly connected to a piston block 503 slidably installed inside the cylindrical tube 501. A vibrating element 504 for driving the sliding rod 502 to move up and down is installed on the cylindrical tube 501. The vibrating element 504 drives the sliding rod 502 to move up and down inside the cylindrical tube 501, thereby realizing the up and down movement of the rotating disk 302. The cylindrical tube 501 guides the sliding rod 502 to prevent the parts from swaying horizontally. With the inclined triangular hook 404, the parts can be effectively prevented from falling during the up and down vibration.

[0029] like Figures 9-10The specific structure of the vibrating element 504 of the present invention is disclosed. The vibrating element 504 includes a tension spring 5041 fixedly connected between the piston block 503 and the top of the inner cylinder 501. An inflation pipe 5042 and an exhaust pipe 5043 are respectively constructed on both sides of the cylinder 501. A sealing block 5044 is inserted into each of the two exhaust pipes 5043, and a pull handle 5045 is connected between the two sealing blocks 5044. A one-way valve 7 is installed in the inflation pipe 5042. The air passage direction of the one-way valve 7 is towards the inside of the cylinder 501. It should be noted that the inflation pipe 5042 and the exhaust pipe 5043 are both connected between the piston block 503 and the top of the inner cylinder 501. When air is inflated into the cylinder 501 through the inflation pipe 5042, the piston block 503 will move downward. The movement causes the tension spring 5041 to stretch. Then, when the parts enter the electrophoresis tank, the handle 5045 can be manually grabbed to pull the sealing block 5044 away from the exhaust pipe 5043. At this time, the piston block 503 loses pressure, and the tension spring 5041 will quickly return to its original position through elastic force, thereby squeezing the gas in the cylinder 501 and quickly expelling it from the exhaust pipe 5043. Afterward, the tension spring 5041 will reciprocate through compression and stretching due to inertia, thereby driving the cylinder 501 to move up and down relative to the slide rod 502. This causes the automotive parts to vibrate up and down in the electrophoresis tank, allowing the remaining air bubbles to be quickly expelled, saving time and improving the overall electrophoresis efficiency. The up and down movement is less than the length of the triangular hook 404 to prevent the parts from falling off.

[0030] like Figure 7 and Figure 10 As shown, the specific structures of the one-way valve 6 and the one-way valve 7 of the present invention are disclosed. Both the one-way valve 6 and the one-way valve 7 include an annular plate 601 and an annular block 602 connected in the inlet pipe 3026, the outlet pipe 3027, and the inflation pipe 5042. A semi-circular groove 603 is constructed on the side of the annular block 602 facing the annular plate 601. A sealing ball 605 is connected to the annular plate 601 by a support spring 604 and abuts against the semi-circular groove 603. It should be noted that gas can only enter from the annular block 602, thereby squeezing the side of the sealing ball 605 facing the annular plate 601. The airflow can smoothly flow into the annular plate 601 through the semi-circular groove 603. When the airflow flows in from the annular plate 601, it will squeeze the sealing ball 605 against the semi-circular groove 603 to prevent the gas from flowing out.

[0031] like Figure 1The specific structure of the driving component 8 of the present invention is disclosed, and it also includes a driving component 8 for driving the rotating column 3022 to rotate and the piston block 503 to move. The driving component 8 includes an insulating frame 801 fixedly connected to the side of the moving frame 101. An air pump 802 is fixedly connected to the insulating frame 801. A vent pipe 803 is connected between one of the air inlet pipes 3026 and air outlet pipes 3027 on two adjacent rotating disks 302. The vent pipe 803 is used to connect the adjacent rotating disks 302. An inflation hose 804 is connected to the other air inlet pipe 3026. An inflation hose 804 is connected to the other air inlet pipe 3026. A diversion hose 805 is provided to connect all the cylindrical tubes 501. The other ends of the diversion hose 805 and the inflation hose 804 are connected to the air pump 802 via a switching valve 806. When electrophoretic coating is required on automotive parts, the automotive parts are first mounted on the support frame 4. Then, the support frame 4 is installed in the hook groove 305 of the L-shaped vertical plate 304. The suspension frame 3 is then hung on the rectangular hanging frame 1 via the hanging rod 301 and the loading and unloading structure 2 to achieve the loading and unloading of the parts. Finally, the sealing block 5044 is inserted into the exhaust pipe 504. In step 3, air pump 802 and diversion hose 805 are used to inflate all cylinders 501 until piston block 503 contacts the bottom of cylinder 501. Then, the rectangular hanging frame 1 is placed into the electrophoresis tank using a mobile device, and the sealing block 5044 is manually removed, causing cylinder 501 to depressurize. Cylinder 501 and rotating disk 302 move rapidly downward relative to piston block 503 under the influence of gravity and the tension of tension spring 5041. Then, inertia causes tension spring 5041 to rebound, thereby causing the components to vibrate up and down, which accelerates the removal of air bubbles from the components. To save settling time and improve overall efficiency, the electrophoresis tank is then powered on. During electrophoresis, the air pump 802 and the air inflator 804 are used to inflate the circular frame 3021, causing the lever 3024 to drive the rotating column 3022 to rotate, thus rotating and swinging the parts to remove air bubbles stuck on the surface of the parts and improve the quality of electrophoretic coating. After electrophoresis is completed, the parts are lifted above the electrophoresis tank and vibrated again by the lifting and vibration mechanism 5, so that the residual liquid in the part cavity can flow out quickly, so as to quickly enter the next process and improve overall efficiency.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
