Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] As Figure 1-2 shown, a metal layer spraying device for thin film capacitors provided by the present invention includes a frame 1, on which a spraying station, a purging station, and a blanking station are provided;

[0044] Rotating and receiving mechanism 2, which is rotatably installed on the above-mentioned frame 1, and the capacitor is placed on the above-mentioned rotating and receiving mechanism 2 and sequentially passes through the above-mentioned three stations;

[0045] Spraying station, on which a movable nozzle 3 is connected to a paint spraying tank;

[0046] Purging station, on which a movable spray gun 4 is connected to an air pipe;

[0047] Blanking station, on both sides of which an inverting mechanism 5 is provided;

[0048] Among them,

[0049] The above-mentioned spraying station and purging station are both located inside the spraying chamber 6, and the blanking station is located outside the spraying chamber 6;

[0050] The working principles and beneficial effects of the above embodiments are as follows:

[0051] The rotating and receiving mechanism 2 of the present invention is installed on the frame 1 and can rotate along the frame 1. The capacitor is placed on the rotating and receiving mechanism 2 and sequentially passes through the spraying station, the purging station, and the blanking station as the rotating and receiving mechanism 2 rotates;

[0052] Spraying station: When the capacitor reaches the spraying station, the movable nozzle 3 is connected to the paint spraying tank, and the nozzle 3 sprays the metal paint evenly on the upper surface of the capacitor along a predetermined route;

[0053] Blowing Station: After the capacitor enters the blowing station, the movable spray gun 4 is connected to the air pipe, and the spray gun 4 blows air along a predetermined route on the sprayed capacitor to remove excess metal paint or impurities, improving the cleanliness of the capacitor;

[0054] Unloading Station: After the capacitor undergoes spraying and blowing treatments and reaches the unloading station, the flipping mechanisms 5 on both sides can flip the capacitor to spray the lower surface of the capacitor;

[0055] The capacitor of the present invention sequentially passes through each station on the rotating receiving mechanism 2 to achieve continuous automated production, reducing manual operation and improving production efficiency; both the spraying station and the blowing station are located inside the spraying chamber, playing an isolation and protection role to prevent the leakage of paint and impurities. The unloading station is located outside the spraying chamber. This layout is reasonable and saves space, making the overall equipment more compact; the unloading station is designed with a flipping mechanism 5 for flipping the capacitor to achieve automated spraying operations on the upper and lower surfaces of the capacitor, improving the production efficiency of the capacitor.

[0056] In one embodiment,

[0057] As Figure 3-4 shown, the above-mentioned rotating receiving mechanism 2 includes a rotating frame 21 rotatably installed on the frame 1. The above-mentioned spraying station, blowing station, and unloading station are respectively located on the same circumference of the rotating frame 21, enabling the capacitor to smoothly transition from one station to the next during rotation, ensuring the continuity and stability of the production process.

[0058] In one embodiment,

[0059] The above-mentioned rotating frame 21 has a rotating central axis. Three rotating frames 21 are circumferentially evenly distributed around its rotating central axis. On the three rotating frames 21, there is a vertical rotating shaft 22 corresponding to the positions of the spraying station, blowing station, and unloading station. On the above-mentioned rotating shaft 22, there is a positioning portion for the turntable 7;

[0060] Three rotating frames 21 are evenly distributed circumferentially, corresponding to the spraying station, blowing and sucking station, and unloading station respectively. On each rotating frame 21, there is a vertical rotating shaft 22. The turntable 7 is sleeved on the rotating shaft 22, and on the rotating shaft 22, there is a positioning portion for the turntable 7, enabling the turntable 7 to maintain stable positioning during rotation, facilitating the operations of spraying, blowing, and flipping processes;

[0061] The above-mentioned positioning portion can be set such that a plug is inserted on one side of the rotating shaft 22, and a slot is opened at the central hole of the turntable 7. The above-mentioned turntable 7 is sleeved on the rotating shaft 22, and the slot is inserted into the above-mentioned plug to achieve circumferential limit of the turntable 7, ensuring the stability of the capacitor during rotation and processing.

[0062] In one embodiment,

[0063] Multiple of the above capacitors are arranged vertically and tied with tape on the turntable 7. The multiple capacitors are arranged vertically, saving space and facilitating the spraying operation on the upper and lower surfaces of the capacitors. The placement method of tying with tape enables the equipment to process multiple capacitors at one time, improving production efficiency.

[0064] In one embodiment,

[0065] As Figure 5-8 shown, the above-mentioned frame 1 extends to the outer end of the spraying chamber 6, and the two above-mentioned flipping mechanisms 5 are oppositely installed on both sides of the frame 1;

[0066] It includes a vertically arranged support frame 51, a lifting component 52 installed on one side of the support frame 51, a translation component 53 installed on the lifting component 52, a flipping component 54 installed on the translation component 53, and a clamping component 55 installed on the flipping component 54;

[0067] The vertically arranged support frame 51 is installed on both sides of the frame 1 to support the flipping mechanism 5 and ensure its stability and rigidity;

[0068] The lifting component 52 is installed on one side of the support frame 51 to drive the translation component 53 and the flipping component 54 to move in the vertical direction; the translation component 53 drives the flipping component 54 and the clamping component 55 to move in the horizontal direction. The flipping component 54 is installed on the translation component 53 and is responsible for driving the clamping component 55 to achieve the flipping action. The clamping component 55 is used to clamp the capacitor;

[0069] When specifically flipping and adjusting the surface of the capacitor, the rotating frame 21 drives the capacitor to rotate to the blanking position. At this time, the operator sleeved another turntable 7 on the rotating shaft 22, so that both ends of the capacitor have the turntable 7. Start the flipping mechanism 5, and the two clamping components 55 clamp the two turntables 7 bidirectionally and move up with the lifting component 52 to disengage from the rotating shaft 22. The flipping component 54 drives it to flip 180 degrees and then sleeve it on the rotating shaft 22. Finally, the operator removes the upper turntable 7 to complete the flipping operation of the capacitor, and then the spraying operation can be continued on the opposite surface of the capacitor;

[0070] The above-mentioned flipping mechanism 5 efficiently and stably completes the flipping operation of the capacitor through the combination of the lifting, translation and flipping components.

A through groove through which the transmission belt 522 passes is provided on the docking surface between the first sliding block and the second sliding block;

[0075] The support frame 51 is designed to be open on one side to facilitate the installation and maintenance of the lifting assembly 52. A slideway is provided on the open side of the support frame 51. The slideway is used to guide the movement of the slider 524 to ensure its smooth movement in the vertical direction. The transmission belt 522 is wound between the two rotating rollers 521. Driven by the motor 523, the transmission belt 522 can move cyclically between the rotating rollers 521;

[0076] The first sliding block is fitted into the slideway and is responsible for sliding in the vertical direction. The second sliding block is docked with the first sliding block. A through groove is provided on its docking surface, and the transmission belt 522 passes through the through groove, thereby driving the slider 524 to move up and down along the slideway;

[0077] Through the design of the transmission belt 522 and the slider 524, the lifting assembly 52 can achieve precise vertical movement, and the sliding of the slider 524 in the slideway ensures the smoothness and linearity of the movement.

[0078] In one embodiment,
