Description

Technical Field

[0001] This utility model relates to the field of electrophoretic processing technology, and in particular to an automatic draining device for automotive parts after electrophoresis. Background Technology

[0002] Electrophoresis is a crucial primer anti-corrosion process in automobile manufacturing. Electrophoresis uses an electric field to allow charged paint particles to penetrate every corner of the workpiece, including the interlayer, cavities, and gaps of sheet metal that are difficult to reach with spraying, forming a complete protective layer to prevent rusting from the inside out.

[0003] After electrophoresis, a large amount of electrophoretic liquid adheres to the surface of automotive parts, requiring a draining process. The traditional draining method involves lifting the automotive parts with clamps for draining, often waiting for the electrophoretic liquid to flow down naturally. This passive draining method consumes a long draining time, resulting in a long electrophoresis processing time and affecting the processing speed of the entire production line.

[0004] Therefore, given that most existing dewatering devices rely on passive dewatering by hanging parts, which requires a long dewatering time, an automatic dewatering device for automotive parts after electrophoresis can be designed. This device uses a combination of active and passive synchronous dewatering to accelerate airflow, shorten the dewatering time of the electrophoretic liquid, save dewatering time, enhance the practical value of the device, and thus effectively shorten the processing speed of the parts production line. Utility Model Content

[0005] In order to overcome the problem that most dewatering devices rely on the electrophoresis liquid to flow down naturally, which consumes a long dewatering time and leads to a long electrophoresis treatment time, thus affecting the processing speed of the entire production line, this utility model is proposed.

[0006] The technical solution of this utility model is as follows: an automatic draining device for automotive parts after electrophoresis, including a base and an electrophoresis tank set on the top of the base, and a draining frame. The draining frame is set above the electrophoresis tank. The placement height of the draining frame can be flexibly adjusted by a first lifting component, so that the draining frame is submerged in the electrophoresis tank or raised for draining. A top frame is set above the draining frame. The placement height of the top frame can be adjusted by a second lifting component, so that the top frame can flexibly close the draining frame. The top plate of the top frame has a hollow structure. Multiple sets of exhaust ducts are equidistantly arranged at the bottom of the top plate of the top frame. The exhaust ducts are controlled by an air supply mechanism to blow air from top to bottom onto the draining frame.

[0007] Preferably, the electrophoresis tank is fixed by a base, and the automotive parts are placed in the draining frame. The height of the draining frame is flexibly adjusted using a first lifting component, lowering it to immerse it in the electrophoresis tank. Due to the weight of the automotive parts, they are immersed in the electrophoresis solution in the draining frame for electrophoresis treatment. Subsequently, the draining frame is raised by the first lifting component to drain the electrophoresis solution from the bottom mesh trough. At the same time, the height of the top frame is adjusted using a second lifting component, lowering it to seal the draining frame. The exhaust fan is controlled by a blower mechanism to blow air from top to bottom onto the draining frame, accelerating the draining speed of the automotive parts in the frame. This achieves the effects of accelerating airflow, shortening the electrophoresis solution draining speed, saving draining time, enhancing the practical value of the device, and shortening the processing speed of the parts production line.

[0008] Preferably, the electrophoresis solution level in the electrophoresis tank is the same as the height of the drain frame, the bottom of the drain frame is set as a grid base plate, and the bottom of the side plate of the drain frame is also provided with a drain groove.

[0009] Preferably, the second lifting assembly includes a fixed plate, a lifting mechanism, and a slider. Two sets of fixed plates are symmetrically arranged at both ends of the outer side of the drain frame. A lifting mechanism is arranged on the inner side of the fixed plate. The lifting mechanism drives the slider to rise and slide. The slider is fixedly connected to the outer side of the top frame. The slider drives the top frame to rise and fall flexibly.

[0010] Preferably, the second lifting assembly also includes a sealing groove and a sealing ring. The bottom end of the top frame has a sealing groove, and the top end of the drain frame has a sealing ring. When the top frame moves down, the sealing ring is embedded in the sealing groove.

[0011] Preferably, the first lifting component includes an electric telescopic rod and a connecting block. Two sets of electric telescopic rods are symmetrically arranged at the top of the base. The electric telescopic rods are located on both sides outside the electrophoresis tank. A connecting block is provided at the outer telescopic end of the electric telescopic rod. One side of the connecting block is fixedly connected to the outer side of the fixed plate. The telescopic electric telescopic rod drives the connecting block to adjust the height of the drain frame.

[0012] Preferably, the air supply mechanism includes an air pump, an air inlet duct, and an air filter. The air pump is installed at the top of the top frame, the air inlet end of the air pump is connected to the air inlet duct, and the air filter is installed at the top of the air inlet duct.

[0013] Preferably, the air supply mechanism also includes an exhaust duct and an air distribution box. The air outlet of the air supply pump is connected to the exhaust duct. An air distribution box is installed inside the hollow structure at the top of the top frame. The other end of the exhaust duct is connected to the air distribution box. Multiple exhaust troughs are opened at the bottom of the air distribution box, and the exhaust troughs are respectively connected to the exhaust hopper.

[0014] The beneficial effects of this utility model are:

[0015] During electrophoresis, automotive parts are placed in a draining frame. The height of the draining frame is lowered so that it is submerged in the electrophoresis tank at the base. Due to the weight of the automotive parts, they are immersed in the electrophoresis solution in the tank for electrophoresis treatment. Subsequently, the draining frame is raised to allow excess electrophoresis solution on the surface of the parts to drain out from the bottom mesh groove. At the same time, the top frame is lowered to seal the draining frame. The exhaust fan is controlled to blow air from top to bottom onto the draining frame, accelerating the draining speed of the automotive parts and saving time on the draining operation. This addresses the problem that most draining devices rely on the electrophoresis solution to flow down naturally, which consumes a long draining time, resulting in a long electrophoresis treatment time and affecting the processing speed of the entire production line. This method shortens the processing speed of the parts production line. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1 and Figure 3This utility model provides an embodiment: an automatic draining device for automotive parts after electrophoresis, including a base 1 and an electrophoresis tank 2 disposed on the top of the base 1, and a draining frame 3 disposed above the electrophoresis tank 2. The electrophoresis liquid level in the electrophoresis tank 2 is the same as the height of the draining frame 3. The bottom end of the draining frame 3 is set as a grid bottom plate, and the bottom of the side plate of the draining frame 3 is also provided with a draining groove. The placement height of the draining frame 3 can be flexibly adjusted by a first lifting component, so that the draining frame 3 is submerged in the electrophoresis tank 2, or raised for draining operation. A top frame 4 is provided above the draining frame 3. The placement height of the top frame 4 can be adjusted by a second lifting component, so that the top frame 4 can flexibly close the draining frame 3. The top plate of the top frame 4 has a hollow structure, and multiple sets of exhaust ducts 5 are equidistantly arranged at the bottom end of the top plate of the top frame 4. The exhaust ducts 5 are controlled by an air supply mechanism to blow air from top to bottom onto the draining frame 3.

[0023] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the second lifting assembly includes a fixed plate 301, a lifting mechanism 302, a slider 303, a sealing groove 304, and a sealing ring 305. Two sets of fixed plates 301 are symmetrically arranged at both ends of the outer side of the drain frame 3. A lifting mechanism 302 is arranged on the inner side of the fixed plate 301. The lifting mechanism 302 drives the slider 303 to rise and slide. The slider 303 is fixedly connected to the outer side of the top frame 4, and the top frame 4 is flexibly raised and lowered by the slider 303. A sealing groove 304 is provided at the bottom end of the top frame 4. A sealing ring 305 is provided at the end. When the top frame 4 moves down, the sealing ring 305 is embedded in the sealing groove 304. The lifting mechanism 302 is fixed by the fixed plate 301. The lifting mechanism 302 drives the slider 303 to slide up and down. The top frame 4 is fixed by the slider 303, thereby driving the top frame 4 to rise and fall flexibly. When the top frame 4 and the drain frame 3 are combined, the sealing ring 305 is embedded in the sealing groove 304 to ensure that the joint between the top frame 4 and the drain frame 3 is sealed and to ensure that the air delivered by the exhaust duct 5 is fully blown to the automotive parts in the drain frame 3.

[0024] The first lifting assembly includes an electric telescopic rod 306 and a connecting block 307. Two sets of electric telescopic rods 306 are symmetrically arranged at the top of the base 1. The electric telescopic rods 306 are located on both sides outside the electrophoresis tank 2. A connecting block 307 is provided at the outer telescopic end of the electric telescopic rod 306. One side of the connecting block 307 is fixedly connected to the outer side of the fixed plate 301. The telescopic electric telescopic rod 306 drives the connecting block 307 to adjust the height of the drain frame 3. The telescopic electric telescopic rod 306 adjusts the height of the connecting block 307. The connecting block 307 is used to connect the fixed plate 301, thereby realizing the effect of flexibly adjusting the placement height of the drain frame 3 by the telescopic electric telescopic rod 306.

[0025] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, the air supply mechanism includes an air pump 501, an air inlet duct 502, an air filter 503, an exhaust duct 504, and an air distribution box 505. The air pump 501 is located at the top of the top frame 4. The air inlet end of the air pump 501 is connected to the air inlet duct 502. The top end of the air inlet duct 502 is equipped with an air filter 503. The air outlet end of the air pump 501 is connected to the exhaust duct 504. The air distribution box 505 is located inside the hollow structure at the top of the top frame 4. The other end of the exhaust duct 504 is connected to the air distribution box 505. Multiple exhaust ducts are provided at the bottom of 505. The exhaust ducts are connected to the exhaust hopper 5 respectively. When the air pump 501 is started, the air intake duct 502 is controlled to draw air. The air in the air intake duct 502 is purified by the air filter 503 and then sent to the air pump 501. The air pump 501 then sends the air to the exhaust duct 504. The air is sent to the air distribution box 505 through the exhaust duct 504. The air distribution box 505 evenly distributes the air and sends the airflow to the exhaust hopper 5. The airflow is then blown into the car parts in the drain frame 3 through the exhaust hopper 5.

[0026] During electrophoresis, the car parts are placed in the drain frame 3. Then, the electric telescopic rod 306 retracts to control the connecting block 307 to move the fixed plate 301 down. The lowered fixed plate 301 reduces the height of the drain frame 3, so that the drain frame 3 is submerged in the electrophoresis tank 2 of the base 1. Because the car parts are heavy, the car parts in the drain frame 3 will be submerged in the electrophoresis solution of the electrophoresis tank 2 for electrophoresis treatment.

[0027] During drainage, the electric telescopic rod 306 is extended to raise the drainage frame 3, so that the height of the drainage frame 3 is higher than the electrophoresis liquid level in the electrophoresis tank 2. At this time, the excess electrophoresis liquid on the surface of the parts is drained out from the bottom mesh groove. At the same time, the lifting mechanism 302 in the fixed plate 301 drives the slider 303 to move down. The slider 303 lowers the height of the top frame 4, so that the sealing ring 305 is embedded in the sealing groove 304. At this time, the top frame 4 seals the drainage frame 3.

[0028] At the same time, the air pump 501 is started to control the air intake duct 502 to draw air. The air in the air intake duct 502 is purified by the air filter 503 and then delivered to the air pump 501. The air pump 501 then delivers the air to the exhaust duct 504. The air is delivered to the air distribution box 505 through the exhaust duct 504. The air distribution box 505 evenly distributes the air and delivers the airflow to the exhaust hopper 5. The airflow is then blown into the car parts in the drain frame 3 through the exhaust hopper 5 to speed up the draining speed.

[0029] Finally, the lifting mechanism 302 drives the slider 303 to move upward, thereby raising the top frame 4, and then the car parts in the drain frame 3 are taken out.

[0030] Through the above steps, by fixing the electrophoresis tank 2 with the base 1, the automotive parts are placed in the draining frame 3. The height of the draining frame 3 is flexibly adjusted using the first lifting component, lowering the draining frame 3 to immerse it in the electrophoresis tank 2. Due to the weight of the automotive parts, the automotive parts in the draining frame 3 will be immersed in the electrophoresis solution in the electrophoresis tank 2 for electrophoresis treatment. Subsequently, the draining frame 3 is raised by the first lifting component to allow the electrophoresis solution to drain out from the bottom mesh groove. At the same time, the height of the top frame 4 is adjusted using the second lifting component, lowering the top frame 4 to close the draining frame 3. The exhaust fan 5 is controlled by the air supply mechanism to blow air from top to bottom onto the draining frame 3, accelerating the drainage speed of the automotive parts in the draining frame 3, thereby speeding up airflow, shortening the electrophoresis solution drainage time, saving drainage operation time, and enhancing the practical value of the device.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
