[0002] The main functions of the lighting circuit board include converting high voltage to low voltage suitable for LED lights, ensuring that the LED lights work properly. It uses an internal step-down chip to convert 220V AC power into the low voltage required by the LED lights, thereby protecting the LED lights from being burned out by high voltage.

[0003] Existing spray painting equipment simply places the cable board directly on the table and then sprays it with paint. This cannot securely fix the circuit board, resulting in poor spray painting stability.

[0004] To address the aforementioned technical issues, CN111992377A discloses a painting device for circuit board production. This device comprises a support housing, a threaded rod, a rotating block, a push rod, and insert plates. The rotating block drives the threaded rod to rotate, which in turn moves the support block on the threaded rod. The push rod then moves the two insert plates, allowing for convenient adjustment of the positions of the two limit plates. Furthermore, the first roller can press the two ends of circuit boards of different sizes together, and the paint spray head is installed at the bottom of the support housing to achieve stable painting of the circuit boards.

[0005] The aforementioned patent also has the following shortcomings: In actual use, the front and back sides of the lighting circuit board need to be painted sequentially for protection, but the existing painting device needs to paint the circuit board twice during the painting process, and cannot achieve the flipping of the board to complete the front and back painting process. Utility Model Content

[0006] The purpose of this utility model is to provide a painting equipment for the production of lighting circuit boards, which has the advantage of being able to paint the front and back sides of the lighting circuit board sequentially, avoiding secondary feeding operations, thereby increasing work efficiency. It adopts a flip-plate method to spray paint the front and back sides sequentially, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a painting equipment for producing lighting circuit boards, comprising a housing:

[0009] The spraying mechanism includes an extraction component and a painting component. The extraction component is located at the top of the housing, and the painting component is located at both ends of the inner cavity of the housing.

[0010] The flipping mechanism includes a power component, a transmission component, and a rotating component. The power component is located on one side of the housing, the transmission component is located on top of the power component, and the rotating component is located outside the transmission component.

[0011] Preferably, the extraction assembly includes a pump, which is fixedly installed on the top of the housing, and the pump's discharge end is connected to a diversion pipe.

[0012] Preferably, the paint spraying assembly includes a delivery pipe connected to the drain end of the diverter pipe, and a spray nozzle is connected to the bottom of the delivery pipe.

[0016] Preferably, the auxiliary component includes a conveyor, which is installed at both ends of the inner cavity of the box, and a partition is fixedly installed at both ends of the top of the inner cavity of the box.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a painting equipment for the production of lighting circuit boards, including a housing 1:

[0027] Both ends of the inner cavity of the box 1 are equipped with a spraying mechanism 2 for spray painting, and the middle of the inner cavity of the box 1 is equipped with a flipping mechanism 3 for flipping the lighting circuit board. Both ends of the inner cavity of the box 1 are equipped with auxiliary components.

[0028] The auxiliary components are mainly used to transport lighting circuit boards and to separate the work area, separating the painting and drying processes, so that the drying process can be carried out after one side is painted.

[0029] The spraying mechanism 2 includes an extraction component and a painting component. The extraction component is located at the top of the housing 1, and the painting component is located at both ends of the inner cavity of the housing 1.

[0030] The extraction and painting components can extract, transport, and spray the required paint.

[0031] The flip-plate mechanism 3 includes a power component, a transmission component, and a rotating component. The power component is located on one side of the housing 1, the transmission component is located on top of the power component, and the rotating component is located outside the transmission component.

[0032] The power output is achieved through the power assembly, transmission assembly, and rotating assembly, which drives the conveyed circuit board to flip over, thereby realizing the flipping operation so that the other side of the lighting circuit board can be sprayed and dried.

[0033] further:

[0034] like Figure 3 As shown, the extraction assembly includes a pump 21, which is fixedly installed on the top of the housing 1. The discharge end of the pump 21 is connected to a diversion pipe 22, which facilitates the extraction of paint into the required pipe for painting.

[0035] like Figure 3 As shown, the paint spraying assembly includes a delivery pipe 23, which is connected to the drain end of the diversion pipe 22. The bottom of the delivery pipe 23 is connected to a nozzle 24, which facilitates the delivery of the extracted paint and makes it easy to spray. A control valve is also installed at the inlet of the delivery pipe 23 to control the paint delivery of the delivery pipe 23 simultaneously or separately.

[0036] When spray painting:

[0037] The paint is directly connected to an external paint pipe via pump 21, then drawn and discharged into a diversion pipe 22, and from there into a delivery pipe 23. Finally, it is sprayed out from the nozzle 24 to complete the paint spraying operation. During the drawing and delivery of paint, since two sets of delivery pipes 23 are provided, two sets of control valves can be used to open and close them simultaneously, and one side can be opened while the other side is closed, so as to facilitate use according to actual needs.

[0038] Preferred:

[0039] like Figure 4 As shown, the power assembly includes a motor 31, which is fixedly installed at the bottom of one side of the housing 1. The output shaft of the motor 31 is keyed to a connecting rod 32, which serves to output power during rotation.

[0040] like Figure 4 As shown, the transmission assembly includes a support plate 33, which is rotatably connected to the outside of the connecting rod 32. One end of the support plate 33 is fixed to one side of the housing 1. A first bevel gear 34 is fixedly installed at the top of the connecting rod 32, and a second bevel gear 35 meshes with the top of the first bevel gear 34, which can realize transmission and auxiliary support work.

[0041] like Figure 4 As shown, the rotating assembly includes a crossbar 36. One end of the second bevel gear 35 is fixedly mounted with the crossbar 36. The crossbar 36 is rotatably connected to the inner side wall of the housing 1. Connecting brackets 37 are fixedly mounted on both sides of the crossbar 36. An adapter groove 38 is provided on the outer side of the connecting bracket 37, which can directly contact the lighting circuit board to perform the flip-plate operation.

[0042] in:

[0043] As shown in the figure, the auxiliary components include a conveyor 4, which is installed at both ends of the inner cavity of the housing 1. A partition 5 is fixedly installed at both ends of the top of the inner cavity of the housing 1. The partition 5 can be used to separate the working areas, with one side being the painting area and the other side being the drying area. The conveyor 4 facilitates the transport of the circuit board to the required position.

[0044] During the flipping process, the conveyor 4 first transports the plate to the connecting frame 37 and the adapter slot 38, and then the motor 31 operates. Subsequently, the motor 31 drives the first bevel gear 34 to rotate through the connecting rod 32, and through meshing, it directly drives the second bevel gear 35 to rotate. Then, the second bevel gear 35 drives the connecting frame 37 and the adapter slot 38 to rotate together through the crossbar 36, and then drives the circuit board inside the adapter slot 38 to rotate together, thereby completing the flipping operation.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
