Description

Technical Field

[0001] The invention belongs to the technical field of automobile lamp production, and in particular relates to a uniform spraying device for automobile lamp production. Background Art

[0002] When driving at night, the quality of car lights directly affects the driver's field of vision. With the development of technology, people pay more and more attention to the quality of car lights. When the car is driving, the bulb in the lampshade works and heats up, while the ambient temperature outside the lampshade is low, which causes a large temperature difference between the inside and outside of the lampshade, causing water vapor to condense on the surface of the lampshade, affecting the normal lighting of the car lights. In order to reduce the probability of water vapor condensing on the surface of the lampshade, an anti-fog layer is usually sprayed on the surface of the lampshade.

[0003] Since the existing lampshade is a curved surface with a large arc, in order to ensure the spraying effect, zone spraying is often carried out, that is, the surface of the lampshade is divided into two parts, front and back, and the surface spraying is completed through a back and forth stroke. However, although this method can ensure the spraying effect of the edge of the lampshade, it cannot ensure the uniformity of the paint in the adjacent areas. Secondly, in order to ensure the spraying effect, an appropriate distance is left between the nozzle and the lampshade, which also causes the atomized paint to escape into the air, which not only causes waste but also pollutes the environment, and seriously damages the health of workers. Summary of the invention

[0004] The object of the present invention is to provide a uniform spraying device for automobile lamp production to solve the problems raised in the above background technology.

[0008] Preferably, the sliding cavity is communicated with the rectangular groove, the sliding plate is adapted to the sliding cavity, and the telescopic rod is fixedly installed inside the base.

[0009] Preferably, the guide shell is fixedly connected to the control valve, the connecting plate is fixedly connected to the control valve, and the elastic plate is fixedly connected to the bottom end of the guide shell.

[0010] Preferably, the column is fixedly connected to the control valve, the output shaft of the driving motor is rotationally connected to the main atomization network, and the sealing plate and the liquid guide plate are both fixedly connected to the inner wall of the liquid chamber.

[0011] Preferably, the fan-shaped plate is adapted to the mixing chamber, the counter-attack block is located above the centrifugal blades, and the main atomization net and the auxiliary annular atomization net are both provided with a plurality of atomization holes.

[0012] Preferably, the guide shell is made of rubber material, the elastic plate is made of elastic material, and the support seat is made of soft magnetic material.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention adjusts the middle of the guide shell to be located in the optimal spraying spacing range through a vertical sliding seat, and then the controller controls the control electromagnet to be energized to work, and at the same time the distance sensor detects the distance between the lampshade. The control electromagnet is energized to generate a magnetic field of the adsorption support seat, thereby driving the elastic plate to deform. When the distance detected by the distance sensor is the middle distance of the guide shell, the suction force of the control electromagnet controlled by the controller nearby will remain unchanged, so that the guide shell is adapted to the curved surface of the lampshade, so that when spraying the paint, uniform spraying without dead angles is performed, thereby solving the problem that although the existing method can ensure the spraying effect of the edge of the lampshade, it cannot ensure the uniformity of the paint in the adjacent area.

[0015] 2. The mixed paint gas of the present invention will be discharged from the bottom end of the guide shell, and thus adhere to the surface of the lampshade. Due to the action of the support seat and the control electromagnet, the paint atomization gas with static electricity will be attracted by the support seat or repelled by the control electromagnet, so that the paint can be quickly attached to the surface of the lampshade, and at the same time, the diffusion of the paint atomization gas in the air is reduced, thereby solving the problem that the atomized paint in the existing method escapes into the air, which not only causes waste but also pollutes the environment and seriously causes damage to the health of workers.

[0016] 3. The present invention drives the counter-attack block and the centrifugal blades on the output shaft to rotate by driving the motor. The counter-attack block and the fan-shaped plate rotate to filter the external air and then draw it into the mixing chamber. Then the annular electromagnet is energized to push the annular permanent magnet to move upward, thereby changing the overlapping area of ​​the atomization holes of the main atomization network and the auxiliary annular atomization network to an appropriate size. The existing electrostatic paint supply device supplies paint to the inside of the liquid chamber. Under the action of the rotating centrifugal blades, the paint is thrown toward the main atomization network and the auxiliary annular atomization network, thereby completing the atomization. When the atomized paint hits the lower surface of the counter-attack block, it moves obliquely downward and mixes with the air drawn into the liquid chamber, further ensuring the uniformity of the spraying effect.

The existing electrostatic paint supply device supplies paint to the interior of the liquid chamber 172. Under the action of the rotating centrifugal blades 175, the paint is thrown to the main atomization net 178 and the auxiliary annular atomization net 1712, thereby completing the atomization.

[0027] Working principle:

[0028] Before using the present invention, the existing electrostatic paint supply device is connected to the liquid chamber 172, and the telescopic rod 10 is in the longest state;

[0029] When the present invention is used, the lampshade 7 to be sprayed is placed on the upper surface of the support seat 4 and fits in place, the telescopic rod 10 is shortened to drive the sliding plate 9 to move to the left, so that the gas pressure inside the columnar channel 6, the rectangular groove 5, and the sliding cavity 8 is reduced to form a negative pressure, thereby firmly adsorbing the lampshade 7 on the upper surface of the support seat 4;

[0030] The vertical sliding seat 2 is moved to the far left or far right by the horizontal sliding seat 1, and then the middle of the guide shell 161 is adjusted to be located in the optimal spraying spacing interval by the vertical sliding seat 2. Then the controller 163 controls the control electromagnet 166 to be energized and work, and at the same time the distance sensor 165 measures the distance to the lampshade 7. The control electromagnet 166 is energized to generate a magnetic field that adsorbs the support seat 4, thereby driving the elastic plate 164 to deform, thereby changing the distance detected by the distance sensor 165 at the corresponding position. When the distance detected by the distance sensor 165 is the middle distance of the guide shell 161, the suction force of the control electromagnet 166 controlled by the controller 163 remains unchanged, so that the guide shell 161 is adapted to the curved surface of the lampshade 7;

[0031] Then the driving motor 174 starts working, driving the counter-block 176 and the centrifugal blades 175 on the output shaft to rotate. The counter-block 176 and the fan-shaped plate 177 rotate to filter the external air through the filter 14 and then suck it into the interior of the mixing chamber 13. Then the annular electromagnet 179 is energized to push the annular permanent magnet 1711 to move upward, thereby changing the overlapping area of ​​the atomization holes of the main atomization net 178 and the auxiliary annular atomization net 1712 to an appropriate size. The existing electrostatic paint supply device supplies paint to the interior of the liquid chamber 172, and under the action of the rotating centrifugal blades 175, the paint is thrown to the main atomization net 178 and the auxiliary annular atomization net 1712, thereby completing The paint is atomized, and when the atomized paint hits the lower surface of the counter-block 176, it moves obliquely downward and mixes with the air drawn into the liquid chamber 172. The control valve 15 is in an open state, and the mixed paint mixed gas is discharged from the bottom end of the guide shell 161, thereby adhering to the surface of the lampshade 7. Due to the action of the support seat 4 and the control electromagnet 166, the paint atomization gas with static electricity will be attracted by the support seat 4 or repelled by the control electromagnet 166, so that the paint quickly adheres to the surface of the lampshade 7, while reducing the diffusion of the paint atomization gas in the air. The horizontal sliding seat 1 moves uniformly to the unsprayed side at a uniform speed until the upper surface of the lampshade 7 is sprayed.
