This type of capacitor is commonly used in electronic circuits and has the advantages of small size, light weight, and good stability. In the manufacturing process of film capacitors, gold spraying is a common processing technology. Gold spraying is a method of spraying a metal film on the electrode surface of a film capacitor to improve conductivity and stability, which can significantly improve the conductivity of the electrode.

The utility model realizes automatic flipping of the film capacitor on the gold spraying tray through the flipping mechanism, which reduces the work intensity of the workers. At the same time, through the spatial distribution of the rotating gear 1, the rotating gear 2 and the teeth 1 and the teeth 2 arranged on the driving gear, the automatic opening and closing of the protective cover when the film capacitor enters and exits the gold spraying cavity and during the gold spraying process is realized, which greatly reduces the overflow of dust and further improves the safety of work. However, the patent does not take into account the problem of uneven spraying caused by the deposition of the spraying material due to long-term placement. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a gold spraying device for film capacitor processing, aiming to improve the problem of uneven spraying caused by the lack of a stirring process in some existing gold spraying equipment, which leads to deposition when the spraying material is placed.

[0008] Furthermore, a delivery pump is fixedly connected inside the mixing barrel, a delivery pipe is fixedly connected to an output end of the delivery pump, and one end of the delivery pipe is fixedly connected to the inside of the fixed plate.

[0009] Furthermore, a recovery box is fixedly connected inside the box body, and a filter is fixedly connected inside the recovery box.

[0010] Furthermore, a pull-out liquid accumulation box is slidably connected inside the recovery box.

[0011] Furthermore, a visual window is provided inside the door, and a handle is fixedly connected to the front side wall of the door.

[0012] The utility model has the following beneficial effects:

[0013] 1. In the utility model, the gear rack, the bottom plate, the gear one, the gear two, the axle, the rotating shaft and the blades are coordinated to achieve the effect of fully mixing the spraying material, and solve the problem that some existing gold spraying equipment does not have a stirring process, which leads to deposition when the spraying material is placed, resulting in uneven spraying.

The above structure improves the uniformity of the coating thickness of the capacitor and improves the recycling of the residual material. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Before starting the gold spraying, you need to open the equipment door 2. The door 2 is equipped with a handle 24. Pull the handle 24 to open the door 2, and place the film capacitor to be processed on the filter 22 inside the equipment. The filter 22 is designed to ensure that the capacitor can be stably placed during the spraying process and prevent the paint from splashing. Pull the handle 24 again to close the door 2. After closing the door 2, you need to prepare the spraying material. At this time, pull the handle 5 to open the bucket cover 4, pour the required spraying material into the mixing bucket 3, and then cover the bucket cover 4 again to ensure that the spraying material will not splash during the mixing process. The motor 6 is started, and the motor 6 starts to drive the bottom plate 8 to rotate, and the gear 1 9 meshes with the gear frame 7. When the bottom plate 8 rotates, the gear 1 9 rotates along the outer wall of the gear frame 7, and the gear 1 9 and the gear 2 10 are connected to each other, so when the gear 1 9 rotates, the gear 2 10 will also rotate, and the rotation of the gear 2 10 further drives the rotation of the axle 11, and the axle 11 is connected to the rotating shaft 12, so when the axle 11 rotates, the blade 13 on the rotating shaft 12 will also move. The design of the blade 13 can fully stir the paint in the mixing barrel 3 to ensure that the paint is evenly mixed.

[0023] Reference Figure 3 An electric slide rail 15 is fixedly connected inside the box body 1, a slider 16 is slidably connected inside the electric slide rail 15, a fixed plate 17 is fixedly connected between the sliders 16, a nozzle 19 is arranged on the lower surface of the fixed plate 17, a delivery pump 14 is fixedly connected inside the mixing barrel 3, a delivery pipe 18 is fixedly connected to the output end of the delivery pump 14, one end of the delivery pipe 18 is fixedly connected inside the fixed plate 17, a recovery box 20 is fixedly connected inside the box body 1, a filter screen 22 is fixedly connected inside the recovery box 20, a liquid extraction box 21 is slidably connected inside the recovery box 20, a visual window 23 is arranged inside the box door 2, and a handle 24 is fixedly connected to the front side wall of the box door 2.

[0024] The stirred paint is transported to the inside of the fixed plate 17 through the delivery pump 14 and the delivery pipe 18. The delivery pump 14 plays the role of extracting the paint from the container and transporting it to the designated position, while the delivery pipe 18 is responsible for guiding the paint to the inside of the fixed plate 17. After the paint enters the inside of the fixed plate 17, the nozzle 19 starts to spray the capacitors that need to be sprayed with gold. At the same time, through the sliding of the slider 16 inside the electric slide rail 15, the fixed plate 17 and the nozzle 19 are moved, so as to achieve uniform spraying of the capacitors on the filter screen 22. After the spraying is completed, the operator can pull the handle 24 to open the box door 2 and take out the sprayed capacitors. Next, the operator pulls the pull-out liquid accumulation box 21 to extract it from the inside of the recovery box 20. The pull-out liquid accumulation box 21 is used to collect the excess paint generated during the spraying process, and the recovery box 20 is used to store the liquid accumulation box. After the recovery is completed, the operator puts the pull-out liquid accumulation box 21 back into the inside of the recovery box 20 for next use.

[0025] Working principle: When it is necessary to spray gold on the film capacitor, pull the handle 24 to open the box door 2, place the capacitor on the upper surface of the filter 22, pull the handle 24 to close the box door 2, pull the handle 5 to open the bucket cover 4, pour the material to be sprayed, and then cover the bucket cover 4 again, start the motor 6, and the motor 6 drives the bottom plate 8 to rotate. Because the gear 1 9 is meshed with the gear rack 7, when the bottom plate 8 rotates, the gear 1 9 will rotate along the outer wall of the gear rack 7. When the gear 1 9 rotates, it will drive the gear 2 10 to rotate. When the gear 2 10 rotates, it will drive the wheel shaft 11 to rotate, thereby driving the blades 13 on the rotating shaft 12 to move, and the mixing barrel 3 is fully stirred to make it mixed evenly, the stirred paint will enter the interior of the fixed plate 17 through the delivery pump 14 and the delivery pipe 18, and then the nozzle 19 will spray the capacitors that need to be sprayed with gold, and at the same time, the slider 16 slides inside the electric slide rail 15, and the slider 16 drives the fixed plate 17 and the nozzle 19 to move, and the capacitors on the filter screen 22 are evenly sprayed. After the spraying is completed, the handle 24 is pulled to open the box door 2, the sprayed capacitors are taken out, and the draw-out liquid accumulation box 21 is pulled out from the inside of the recovery box 20 to recycle the collected paint. After the recycling is completed, the draw-out liquid accumulation box 21 is put back into the inside of the recovery box 20.
