Description

Technical Field

[0001] The present invention relates to the field of auxiliary equipment for spraying paint on the inner surface of vehicle lamps, and in particular to an auxiliary device and kit for spraying paint on vehicle lamps. Background Art

[0002] In the current production process of automotive lamps, after the lamps are injection molded, the inner surface of the exterior lamps needs to be sprayed with anti-fog paint. With technological advancements, painting is now mostly done on automated production lines. The lamps are placed on a pallet on a cross-shaped turntable. After painting one lamp, the turntable moves away and the next lamp is painted. The anti-fog paint is applied to the inner surface from the bottom up, but this existing spraying process has at least the following drawbacks:

[0003] 1. When spraying anti-fog paint, the spray gun sprays too much at the moment of starting up, and the paint sprayed by the spray gun is also uneven. Therefore, the paint cannot be sprayed directly onto the inner surface of the lamp. It is necessary to wait for a while until the sprayed paint is stable and even before moving to the product for spraying. During this waiting period, the paint sprayed by the spray gun can only be sprayed onto the blank space next to the product or into the air, which causes a large amount of paint to accumulate on the workbench next to the product and needs to be cleaned, or a lot of paint is diffused in the air, causing air pollution. Since this process does not last long, the paint waste and pollution caused are not very serious. Therefore, the shortcomings brought about by this aspect are usually ignored in the production link of the industry, and no innovation has been made to change this problem for many years.

[0004] 2. Whether it is the uneven paint sprayed when the spray gun is just turned on, or the paint sprayed after the spray gun is officially working, there will be a lot of paint residue on the tray where the headlights are placed. This part of the paint residue needs to be manually wiped and cleaned at regular intervals, which increases labor costs and reduces production efficiency. Similarly, cleaning the tray every once in a while has become the norm in the industry and has become one of the necessary steps in the production process. The technical staff in the industry have not made any innovations in this regard for many years and have been using this production process for many years.

[0005] 3. During the production process, after the headlights are painted, paint drips from the headlights themselves and flows down to the pallet, further increasing the frequency of cleaning and maintenance, thereby increasing labor costs and reducing production efficiency. Furthermore, because this dripping problem is a relatively minor issue, the indirect increase in labor costs is easily overlooked. Therefore, the industry has generally adapted to the process of cleaning the pallet every working period to address this issue. For many years, no innovation has been made to solve this problem.

[0006] 4. In addition, since the anti-fog paint on the inner surface of the headlight is sprayed from bottom to top, it is inconvenient to clean. The tray needs to be turned over to facilitate wiping and cleaning by the staff, which also increases the cleaning procedures and labor costs.

[0007] 5. In the existing process of painting headlights, one headlight was originally sprayed at a time. Later, with the development of technology, two headlights can be sprayed simultaneously as a group. However, the left and right headlights on the vehicle are in different directions. Therefore, producing two headlights on the same side at the same time, or producing a group of left and right headlights at the same time, can easily cause confusion in the actual operation of front-line production workers, resulting in production errors. Summary of the Invention

[0008] The object of the present invention is to solve at least some of the existing problems.

[0009] To solve the above technical problems, the present invention provides a headlight painting auxiliary device, comprising:

[0012] The tray is provided with a detachably connected paint spraying mold, and the paint spraying mold is located above the paint spraying port and seals the paint spraying port.

[0013] As a preferred embodiment of the vehicle lamp painting auxiliary device of the present invention, at least one side of each of the collecting tanks is provided with a discharge port.

[0014] As a preferred embodiment of the vehicle lamp painting auxiliary device of the present invention, an edge of the tray connected to the collecting tank is provided with an at least partially inclined connection portion.

[0015] As a preferred embodiment of the vehicle lamp painting auxiliary device of the present invention, the tray is provided with at least one gun starting chamber protruding from bottom to top; the gun starting chamber is provided with at least one drainage hole.

[0016] As a preferred embodiment of the vehicle lamp painting auxiliary device of the present invention, each of the gun-starting chambers is provided with an inverted inner cavity at least surrounding its periphery.

[0017] As a preferred embodiment of the vehicle lamp painting auxiliary device of the present invention, the tray is provided with at least one paint storage box which is concave from top to bottom;

[0018] The tray is provided with a paint guide groove surrounding the paint spray port; the lower edge of the paint spray mold is located in the paint guide groove; the paint guide groove includes a vertically arranged discharge hole, and the discharge hole is located above the paint storage box.

[0019] The headlight painting auxiliary kit of the present invention includes at least two headlight painting auxiliary devices as described in any of the foregoing items, wherein two adjacent trays are arranged in parallel and at the same height, and one of the trays is provided with an anti-foolproof notch piece, and the other tray is provided with an anti-foolproof tooth piece; the anti-foolproof notch piece and the anti-foolproof tooth piece are detachably connected.

[0020] As a preferred embodiment of the headlight painting auxiliary kit of the present invention, at least one of the sides outside the gun chamber is provided with a scanning area.

[0021] Beneficial effects

[0022] The present invention has at least the following innovative advantages:

[0023] 1. The headlight painting auxiliary device of the present invention is provided with a paint spray port and a paint spray mold connected to the paint spray port. The paint spray port and the paint spray mold can allow the anti-fog paint of the spray gun to pass through the interior thereof and be sprayed evenly onto the surface of the headlight. The tray can shield and collect most of the diffused paint sprayed by the spray gun. The collection troughs provided on at least two sides of the tray can not only further shield the paint sprayed by the spray gun, but also allow the paint scattered on the surface of the tray to flow into the interior thereof, thereby collecting the paint, extending the production time, reducing the sagging of the paint on the surface of the tray, and greatly reducing the problem of increased labor costs caused by repeated wiping of excessive paint overflowing from the surface, thereby indirectly improving production efficiency.

[0024] 2. The vehicle lamp painting auxiliary device of the present invention solves the problem of discharging and cleaning the paint in the collection tank by providing a discharge port, thereby avoiding the problem of excessive paint in the collection tank overflowing.

[0025] 3. The headlight painting auxiliary device of the present invention provides an inclined connection portion at the edge where the tray connects to the collection trough, so that paint accumulated on the lower surface of the tray can flow into the collection trough through the connection portion, thereby improving the effect of the collection trough in collecting paint on the tray surface, thereby further reducing paint dripping and reducing labor costs.

[0026] 4. The headlight painting auxiliary device of the present invention has at least one starting chamber provided on the tray, so that during operation, the spray gun can be aligned with the starting chamber when the machine is turned on, so that the paint sprayed by the spray gun at the time of starting can be sprayed into the starting chamber. The spray gun can be moved to continue painting after the paint sprayed by the spray gun is stable and uniform. The provision of the starting chamber solves the problem of excessive and uneven spraying of the spray gun at the moment of starting the machine, which causes excessive accumulation of paint on the workbench and increases air pollution when sprayed into the air, greatly improving the original high production cost in the industry. The drainage hole makes it convenient to flip the tray vertically to drain the paint in the starting chamber when cleaning the tray.

[0027] 5. The headlight painting auxiliary device of the present invention has an inverted inner cavity surrounding the periphery provided in the gun starting chamber, so that the paint sprayed into the interior by the spray gun can be stored or collected in the inverted inner cavity, thereby preventing the paint from flowing downward from the gun starting chamber for a second time; ultimately, the effect is further improved, and the problem of excessive and uneven spraying of the spray gun at the moment of just starting up, resulting in excessive accumulation of paint on the workbench caused by spraying, and increased air pollution caused by spraying in the air.

[0028] 6. The headlight painting auxiliary device of the present invention comprises a paint storage box with a downwardly concave shape on the surface of a tray, a paint guide groove surrounding the paint spray port on the tray surface, and a paint spray mold positioned within the guide groove. This allows paint dripping from the inner wall of the spray mold to flow into the guide groove during painting. This reduces the labor cost of cleaning the tray during production due to paint dripping from the spray mold onto the tray surface, and eliminates the need to clean the tray every once in a while.

[0029] At the same time, the discharge hole of the paint guide groove is located above the paint storage box, so that the paint in the paint guide groove flows into the paint storage box uniformly, thereby solving the problem of paint dripping inside the spray paint mold. The liquid paint inside the spray paint mold can be collected and cleaned without turning over the tray, which greatly reduces the cleaning procedure and labor costs.

[0030] 7. The headlight painting auxiliary kit of the present invention arranges the trays of at least two headlight painting auxiliary devices in parallel, and provides an anti-fool-proof notch piece and the anti-fool-proof tooth piece for detachable connection. When it is necessary to produce two headlights on the same side or to produce a group of left and right headlights at the same time, the two corresponding headlight painting auxiliary devices are matched in advance through the anti-fool-proof notch piece and the anti-fool-proof tooth piece, so that different headlights are inconvenient to be installed on the paint mold of the headlight painting auxiliary device, thereby avoiding the problem of production errors caused by confusion during operation by front-line production workers.
