Description

Technical Field

[0001] The present invention relates to the technical field of frame painting devices, and in particular to an environment-friendly electric vehicle frame painting device and a using method thereof. Background Technique

[0002] An electric vehicle, that is, an electric drive vehicle, also known as an electric car, is a vehicle that uses a battery as an energy source. It converts electrical energy into mechanical energy through components such as a controller and a motor, and then drives the vehicle forward. By controlling the magnitude of the current, the speed of the vehicle can be changed. An electric vehicle frame painting device is a workshop spraying device designed specifically for electric vehicle frames. Such devices aim to improve spraying efficiency, ensure spraying quality, and minimize the impact on the workshop environment. However, although existing electric vehicle frame painting devices can perform high-efficiency automatic and uniform spraying on the frame, the paint on the surface cannot dry and solidify quickly after spraying. At the same time, there is no shielding structure, and the sprayed paint is likely to fall onto the working area, resulting in difficulty in cleaning.

[0003] In response to the above problems, in the "A Painting Device for Electric Bicycle Frames" with Chinese Publication No.: CN220573851U, the setting of the blowing component can make the paint on the surface of the frame dry and solidify quickly after spraying, facilitating the next process. Through the setting of the lifting component, it is convenient for the blowing component to lift and lower, and can comprehensively air-dry the surface of the frame. And through the clamping and rotating component, the frame can be rotated, facilitating the painting and air-drying of the frame surface.

[0004] However, when this kind of frame painting device is in use, there are still certain defects. For example, the paint contains volatile organic compounds, and these compounds will volatilize into the air during the spraying process, causing harm to the environment and human health. When this kind of frame painting device is in use, the waste gas generated during the painting and drying processes is directly discharged into the atmosphere, which will have a negative impact on air quality. In addition, impurities may be mixed in during the production process of the paint or when it is poured into the painting device. During painting, it is easy to cause the nozzle to be blocked, resulting in downtime and seriously affecting the painting efficiency. Summary of the Invention

[0033] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Please refer to Figures 1 - 2 In this embodiment, an environment-friendly electric vehicle frame painting device is provided, including: a spraying base 1, a painting block 3 is arranged above the spraying base 1, a top cover 7 is arranged above the spraying base 1, and a transparent protection cover 8 is arranged inside the top cover 7; a purification component arranged between the spraying base 1 and the top cover 7 for air purification and frame drying; the purification component includes: a water washing chamber 5 opened inside the spraying base 1, a vacuum pump 501 is arranged inside the spraying base 1, a dust filter cover 503 is arranged on the top of the spraying base 1, a suction pipe 502 is arranged on the top of the vacuum pump 501, and the top end of the suction pipe 502 extends into the dust filter cover 503, a guide air pipe 504 is arranged at the bottom of the suction pipe 502, the bottom end of the guide air pipe 504 extends into the water washing chamber 5, a liquid inlet pipe is connected to one side of the water washing chamber 5, a liquid discharge pipe is connected to one side of the water washing chamber 5, a guide air hose 603 is arranged on one inner wall side of the water washing chamber 5, a drying box 6 is arranged inside the top cover 7, an electric telescopic rod a 604 is arranged on the top of the spraying base 1, the bottom end of the electric telescopic rod a 604 extends into the top cover 7 and is fixedly connected to the drying box 6, and one end of the guide air hose 603 is fixedly connected to the drying box 6; a plurality of heating rods 601 arranged inside the drying box 6, an air outlet 602 is opened on one side of the drying box 6, a plurality of electric telescopic rods b 9 are arranged between the spraying base 1 and the top cover 7, a display screen 901 is arranged on one side of the spraying base 1, and a rubber ring is arranged at the bottom of the spraying base 1.

[0035] Further, when spraying paint, the vacuum pump 501 can be turned on to extract the air from the spraying space formed by the spraying base 1 and the top cover 7, so as to extract the paint particles floating in the spraying space and the volatile waste gas in the paint, and enable the particles and waste gas in the air to enter the water washing cavity 5 through the suction pipe 502 and the air guide pipe 504, so as to filter these particles and waste gas through the solution in the water washing cavity 5. And these filtered air can be introduced into the drying box 6 through the air guide hose 603, and discharged into the spraying space through the air outlet 602, and then be extracted by the vacuum pump 501 again, so that these air circulates and filters inside to improve the filtering effect.

[0036] Meanwhile, when it is necessary to dry the paint on the surface of the vehicle frame, the painting pump 102 is turned off, the air inside the spraying space is continuously extracted by the vacuum pump 501, then multiple heating rods 601 inside the drying box 6 are turned on, and the vehicle frame is rotated by the servo motor a2. At the same time, the electric telescopic rod a604 is controlled to extend, so that the drying box 6 moves up and down along the vehicle frame.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 10 In [references], an observation component is provided inside the top cover 7. The observation component includes: a gear cavity 701 is provided on the inner wall of the top cover 7, and a main gear 702 is provided inside the gear cavity 701; multiple cameras 801 are provided inside the transparent protection cover 8.

[0038] Please refer to Figure 2 、 Figure 7 and Figure 10 In [references], a servo motor b704 is provided inside the top cover 7, and the servo motor b704 is connected to the main gear 702 through a rotating shaft. One side of the transparent protection cover 8 is fixedly connected to an annular toothed plate 703, and multiple teeth are provided on the outside of the annular toothed plate 703, and the main gear 702 is meshed with the multiple teeth on the outside of the annular toothed plate 703. Through the setting of the main gear 702 and the annular toothed plate 703, the transparent protection cover 8 and the multiple cameras 801 are driven to rotate.

[0039] Please refer to Figure 2 and Figure 4In it, a connecting shaft 203 is fixedly connected to the bottom end of the connecting plate 204, and the bottom end of the connecting shaft 203 is connected to the upper clamping plate 202 through a bearing. The bottom end of the servo motor a2 is connected to the lower clamping plate 201 through a rotating shaft, and the lower clamping plate 201 corresponds to the position of the upper clamping plate 202. During use, the vehicle frame to be painted can be placed on the top of the lower clamping plate 201, and then the electric push rod b205 is controlled to extend. The connecting plate 204 and the upper clamping plate 202 are driven by the electric push rod b205 to move downward, and the bottom of the upper clamping plate 202 is brought into contact with the top of the vehicle frame to clamp the vehicle frame.

[0040] Please refer to Figure 2 , Figure 5 and Figure 8 In FIGS.

[0041] Please refer to Figure 2 , Figure 3 and Figure 8 In it, an anti-blocking component is provided inside the paint spraying block 3. The anti-blocking component includes: a paint storage cavity 101 opened inside the spraying base 1, a paint spraying pump 102 provided inside the paint storage cavity 101, a temporary storage cavity a301 opened inside the paint spraying block 3, and a main spray head 302 connected to one side of the inner wall of the temporary storage cavity a301; a temporary storage cavity b4 opened inside the paint spraying block 3, and a spare spray head 401 connected to one side of the inner wall of the temporary storage cavity b4. A spring cavity 307 is opened inside the paint spraying block 3. Through the setting of the spare spray head 401, when the main spray head 302 is blocked, it can be switched to the spare spray head 401 to prevent the problem that the paint cannot be discharged and the equipment is damaged.

[0042] Please refer to Figure 3 and Figure 5 In FIGS.

[0043] Please refer to Figure 2 and Figure 8Inside, a spring 308 is provided inside the spring chamber 307, a limiting plate 306 is provided inside the spring chamber 307, a connecting rod 305 is fixedly connected to the bottom of the limiting plate 306, a through hole 303 is opened at the top of the inner wall of the temporary storage chamber a301. Through the setting of the spring 308, the plugging and opening of the through hole 303 by the piston 304 can be controlled.

[0044] Please refer to Figure 8 Inside, the bottom end of the connecting rod 305 extends into the through hole 303 and is fixedly connected to a piston 304. A sealing ring is sleeved outside the piston 304, and the piston 304 is located inside the through hole 303.

[0045] When impurities in the paint cause the main nozzle 302 to be blocked, the paint spraying pump 102 continuously injects paint into the temporary storage chamber a301. At this time, the paint gradually accumulates inside the temporary storage chamber a301. When it accumulates to a certain extent, the paint inside the temporary storage chamber a301 will exert an upward thrust on the through hole 303, thereby driving the connecting rod 305 and the limiting plate 306 to squeeze the spring 308, and further moving the piston 304 into the temporary storage chamber b4, and making the temporary storage chamber a301 communicate with the temporary storage chamber b4. At this time, the paint inside the temporary storage chamber a301 can enter the temporary storage chamber b4 through the through hole 303 and reach the vehicle frame from the spare nozzle 401. In addition, both sides of the paint spraying block 3 are connected to the sealing plate by bolts. When it is necessary to clean the inside of the paint spraying block 3, the user can remove the bolts and the sealing plate, and then the inside of the paint spraying block 3 can be rinsed.

[0046] The working principle is as follows: During use, the user can place the vehicle frame to be painted on the top of the lower clamping plate 201, and then control the electric push rod b205 to extend. By driving the connecting plate 204 and the upper clamping plate 202 to move downward through the electric push rod b205, and making the bottom of the upper clamping plate 202 contact the top of the vehicle frame to clamp the vehicle frame.

[0047] Then control multiple electric telescopic rods b9 to retract, drive the top cover 7 to move downward, and make the rubber ring at the bottom of the top cover 7 contact the top of the spraying base 1, so as to form a relatively sealed spraying space between the spraying base 1 and the top cover 7. Then start the servo motor a2, drive the lower clamping plate 201 to rotate through the servo motor a2, and drive the vehicle frame to rotate. At this time, start the paint spraying pump 102 inside the paint storage chamber 101, and then make the paint enter the temporary storage chamber a301 through the paint suction pipe 103, the paint outlet pipe 104 and the hose 105, and be sprayed onto the surface of the vehicle frame from the main nozzle 302. At this time, cooperate with the servo motor a2 to rotate the vehicle frame, and at the same time start the electric push rod a106 to control retraction to spray the vehicle frame comprehensively.

[0048] When impurities in the paint cause the main nozzle 302 to become blocked, the paint spraying pump 102 continuously injects paint into the temporary storage chamber a301. At this time, the paint gradually accumulates inside the temporary storage chamber a301. When it accumulates to a certain extent, the paint inside the temporary storage chamber a301 exerts an upward thrust on the through hole 303, thereby driving the connecting rod 305 and the limiting plate 306 to squeeze the spring 308, and then causing the piston 304 to move into the temporary storage chamber b4, and making the temporary storage chamber a301 communicate with the temporary storage chamber b4. At this time, the paint inside the temporary storage chamber a301 can enter the temporary storage chamber b4 through the through hole 303 and reach the vehicle frame from the spare nozzle 401. In addition, both sides of the paint spraying block 3 are connected to the sealing plate by bolts. When it is necessary to clean the inside of the paint spraying block 3, the user can remove the bolts and the sealing plate, and then can wash the inside of the paint spraying block 3.

[0049] When spraying paint on the vehicle frame, the user can turn on the servo motor b704, rotate the main gear 702 through the servo motor b704, and then drive the annular toothed plate 703 through the main gear 702, thereby driving the transparent protective cover 8 and the camera 801 to rotate inside the top cover 7. At this time, turn on the transparent protective cover 8 and the camera 801, and the spraying process of the vehicle frame can be photographed, and the photographed image can be transmitted to the display screen 901 for the user to monitor in real time. At the same time, since a scraping plate 803 is provided inside the top cover 7 and one side of the scraping plate 803 is in contact with one side of the transparent protective cover 8, when the transparent protective cover 8 rotates, the scraping plate 803 can scrape off the paint adhering to the surface of the transparent protective cover 8 to prevent the paint from adhering to one side of the transparent protective cover 8 and affecting the image shooting of the camera 801.

[0050] Furthermore, when spraying paint, the vacuum pump 501 can be turned on to evacuate the spraying space formed by the spraying base 1 and the top cover 7, so as to extract the paint particles floating in the spraying space and the volatile waste gas in the paint, and make the particles and waste gas in the air enter the water washing chamber 5 through the suction pipe 502 and the air duct 504, so as to filter these particles and waste gas through the solution inside the water washing chamber 5. And these filtered air can be introduced into the drying box 6 through the air duct hose 603 and discharged into the spraying space from the air outlet 602, and be extracted by the vacuum pump 501 again, so that these air circulates and filters inside to improve the filtering effect.

[0051] Meanwhile, when it is necessary to dry the paint on the frame surface, the paint spraying pump 102 is turned off, the air inside the spraying space is continuously extracted by the vacuum pump 501, and then multiple heating rods 601 inside the drying box 6 are turned on. The frame is rotated by the servo motor a2, and at the same time, the electric telescopic rod a604 is controlled to extend, so that the drying box 6 moves up and down along the frame. At this time, the air discharged through the air guide hose 603 enters the drying box 6 and drives the heat of the multiple heating rods 601 to blow towards the frame to dry the paint on the frame surface.

[0052] In addition, a control panel is provided on one side of the spraying base 1. The control panel can control the opening and closing of the paint spraying pump 102, the electric push rod a106, the servo motor a2, the electric push rod b205, the vacuum pump 501, the heating rods 601, the electric telescopic rod a604, the servo motor b704, the camera 801, and the electric telescopic rod b9, and the electric energy of this device is provided by an external power source.
