Description

Technical Field

[0001] The invention relates to the technical field of capacitor spraying, in particular to a spraying device for capacitor film production. Background Art

[0002] Two conductors close to each other with a layer of non-conductive insulating medium in between constitute a capacitor. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge. The capacitance of the capacitor is numerically equal to the ratio of the charge on one conductive plate to the voltage between the two plates. The basic unit of the capacitance of a capacitor is farad. In circuit diagrams, the letter C is usually used to represent the capacitor element. Capacitors play an important role in tuning, bypass, coupling, filtering and other circuits. They are used in the tuning circuit of transistor radios, and in the coupling circuit and bypass circuit of color TVs. With the rapid development of electronic information technology, the replacement speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products, mainly flat-screen TVs, laptops, digital cameras, etc., continue to grow, driving the growth of the capacitor industry. Spraying is a coating method that uses a spray gun or a disc atomizer to disperse into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the coated object. It can be divided into air spraying, airless spraying, electrostatic spraying and various derivative methods of the above basic spraying forms, such as high-flow low-pressure atomization spraying, thermal spraying, automatic spraying, multi-group spraying, etc. When some capacitors are used in production, they need to undergo thin-film production spraying operations on their surfaces.

[0003] For example, the patent document with the announcement number CN 114733664 B discloses a spraying device for producing glass glaze capacitor film, including a shell, the top of which is fixedly connected to a top plate, a capacitor shell limiting mechanism is provided on the top of the top plate, a medium storage box is fixedly installed on one side of the shell, a controller is fixedly installed on the other side of the shell, a motor is fixedly installed on the bottom wall of the shell, a uniform spraying mechanism is provided at one end of the output shaft of the motor, and a spraying slot is provided on the top of the top plate. The present invention realizes uniform spraying of the surface of the capacitor to be sprayed with glass glaze through a uniform spraying mechanism, and at the same time, the data obtained by the capacitor shell thickness detection mechanism is transmitted to the spraying adjustment mechanism to realize different degrees of opening of the spray valve for capacitors of different diameters, thereby achieving uniform spraying, and realizing efficient spraying of glass glaze on the surface of capacitor shells of different specifications and diameters, with a high degree of automation and good application prospects.

[0004] However, when this structure is used for actual capacitor film spraying, due to the limitation of its own structure, it can only perform single-nozzle spraying operation on the capacitor surface, and its efficiency of capacitor spraying is low. In addition, due to the single-nozzle structure, it is very easy to cause the problem of poor uniformity of film spraying on the capacitor after spraying, and the equipment cannot adjust the stable limit of the equipment during the entire spraying process of the capacitor. At the same time, the equipment cannot perform the anti-overflow absorption operation of floating paint during the spraying process, and the paint cannot be dried and solidified in the first time after the spraying is completed. It is impossible to perform higher-quality capacitor film production spraying work and cannot meet daily use needs. Therefore, it is urgent to design a capacitor film production spraying device to solve the above problems. Summary of the invention

[0035] Working principle: When in use, the user first puts the capacitor that needs to be surface-film sprayed into the inner center of the spray hood frame 1, and uses the positioning material frame 43 and the inner wall protective rubber ring 44 on the top of the movable top frame 11 to perform protective positioning and loading and unloading operations on the capacitor. Then, the lifting motor 35 inside the motor frame 34 at the bottom of the driving frame 6 is started first, so that it drives the lifting screw 36 inside the driving frame 6 to rotate, thereby driving the lifting ring seat 7 and the driving ring frame 8 as a whole to perform lifting and adjusting operations around the capacitor inside the spray hood frame 1 through the screw rod sliding sleeve 37 sleeved on the outer surface, and synchronously starts the driving motor 32 on the surface of the limiting slide 31 to drive the driving gear 33 at one end to drive the side of the driving ring frame 8 inside the lifting ring seat 7.
