Description

Technical Field

[0002] Metallized film capacitors are capacitors in which a very thin metal film is deposited on a plastic dielectric using a vacuum evaporation method to replace the metal foil as the electrode. Metallized film capacitors have self-healing properties and excellent characteristics such as good voltage withstand performance, wide frequency response, low dielectric loss, and high insulation resistance. They have been widely used in various fields, and the market demand is increasing day by day.

[0003] In the manufacturing process of metallized film capacitors, an energizing process is required. The purpose of energizing is to impart a certain amount of energy (voltage, current, and time) to the capacitor, capture weaknesses such as electric field impurities, cause them to break down and continuously discharge to achieve electrode insulation recovery. Through the energizing effect, the capacitor can fully and effectively self-heal during the manufacturing process, minimizing the occurrence of self-healing during use and improving product reliability. The energizing process can remove impurities in the dielectric of the film capacitor, improving product reliability and lifespan, and is particularly important in the metallized film capacitor manufacturing process.

[0004] Most common capacitor energizing test devices currently use manual feeding, where the metallized film capacitor is clamped by a test fixture, and the two leads of the metallized film capacitor are brought into contact with each pair of test contacts to perform energizing tests. This is inconvenient to operate and has low testing efficiency. Therefore, there is a need to design a metallized film capacitor energizing device that can automatically feed and test the capacitor while being easy to operate. Utility Model Content

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a metal thin-film capacitor energizing device.

[0029] Reference Figures 1 to 5 A metal film capacitor energizing device includes a frame 1 and a feeding mechanism 2 mounted on the frame 1. The feeding mechanism 2 is a transmission belt, on which multiple capacitors 3 are conveyed. A detection mechanism 4 and a pushing mechanism 5 are respectively arranged on both sides of the feeding mechanism 2. A limit baffle is provided on the feeding mechanism 2, and a sensor is provided on the limit baffle. In this embodiment, the sensor is an infrared sensor, which is electrically connected to the pushing mechanism 5. The detection mechanism 4 includes a first turntable 401 and a second turntable 402 arranged concentrically. Both the first turntable 401 and the second turntable 402 are vertically arranged. A fixed seat 401a and a clamping seat 402a are respectively provided on the first turntable 401 and the second turntable 402. The fixed seat 401a and the clamping seat 402a are electrically connected to a capacitance tester. The pushing mechanism 5 is arranged perpendicular to the length direction of the feeding mechanism 2 and can push the capacitors 3 between the fixed seat 401a and the clamping seat 402a.

[0030] Reference Figures 1 to 5 The feeding mechanism 5 includes a feeding cylinder 501. A push plate 501a and a support plate 501b are connected to the output end of the feeding cylinder 501. The push plate 501a and the support plate 501b are located on the side and below the feeding mechanism 2, respectively. The length of the support plate 501b is greater than the length of the push plate 501a, and the length difference between the support plate 501b and the push plate 501a is not less than the size of the capacitor 3. A pressing cylinder 502 is provided above the feeding cylinder 501. A pressing plate 502a is connected to the output end of the pressing cylinder 502, and the pressing plate 502a can press and fix the capacitor 3 and the support plate 501b. Specifically, the pressing plate 502a is an inclined elastic plate. One end of the pressing plate 502a is connected to the pressing cylinder 502, and the other end of the pressing plate 502a is provided with a downward bending section and a horizontal section is connected to the bending section. The horizontal section can be connected to the upper end of the capacitor 3.

[0031] Reference Figures 1 to 5 Multiple fixing seats 401a and multiple clamping seats 402a are respectively provided on the first turntable 401 and the second turntable 402. The fixing seats 401a and clamping seats 402a are evenly arranged circumferentially and the number of fixing seats 401a and clamping seats 402a is equal. The fixing seats 401a are fixedly connected to the first turntable 401. The clamping seats 402a are disposed through the second turntable 402 and a spring is disposed between the clamping seats 402a and the second turntable 402. A clamping mechanism 6 is provided on the side of the clamping seat 402a. Specifically, if the spring is located on the side of the second turntable 402 and close to the first turntable 401, the spring is a compression spring; if the spring is located on the side of the second turntable 402 and away from the first turntable 401, the spring is a tension spring. Both spring settings are acceptable, as long as the spring force is directed towards the first turntable 401. In this embodiment, the spring is located inside the clamping seat 402a.

[0032] Reference Figure 1 and Figure 5 The clamping mechanism 6 includes a clamping cylinder 601. A fixed clamp 602 is connected to the output end of the clamping cylinder 601. The fixed clamp 602 is provided with a groove. The end of the clamping seat 402a is provided with a protrusion corresponding to the groove. A position detection sensor is provided on the side of the fixed clamp 602. The position detection sensor is electrically connected to the clamping cylinder 601 and the pushing mechanism. Specifically, the position detection sensor is electrically connected to the unloading cylinder 501 and the pressing cylinder 502.

[0033] The implementation principle is as follows: This application sets up a detection mechanism 4 and a pushing mechanism 5 on both sides of the feeding mechanism 2. The pushing mechanism 5 can directly push the capacitor 3 on the feeding mechanism 2 between the fixed seat 401a and the clamping seat 402a of the detection mechanism 4, which is convenient for feeding. By setting up a first turntable 401 and a second turntable 402 with corresponding fixed seats 401a and clamping seats 402a, the feeding position can be adjusted during the rotation of the first turntable 401 and the second turntable 402, which is convenient for continuous detection work and improves detection efficiency.

[0034] In use, the feeding mechanism 2 conveys multiple capacitors 3. The first turntable 401 and the second turntable 402 rotate intermittently, and each rotation provides a pair of fixed seats 401a and clamping seats 402a located on the side of the feeding mechanism 2. The end of the clamping seat 402a can be engaged in the fixed clamp 602. As a prerequisite, when the capacitor 3 reaches the position of the limit baffle, the sensor sends a signal to the clamping mechanism 6 and the pushing mechanism 5. The clamping cylinder 601 drives the fixed clamp 602 to retract, thereby driving the clamping seat 402a to move, and then the pressing cylinder 5... 02 and the pushing cylinder 501 act sequentially to push the capacitor 3 between the fixed seat 401a and the clamping seat 402a. Then, the clamping cylinder 601 resets, and the clamping seat 402a and the fixed seat 401a clamp and fix the capacitor 3. Finally, the pressing cylinder 502 and the unloading cylinder 501 reset. The first turntable 401 and the second turntable 402 rotate, driving the capacitor 3 to move and perform energization detection. The above steps are repeated, and the feeding mechanism 2 continuously feeds the capacitor. The rotation of the first turntable 401 and the second turntable 402 realizes the switching of the detection position, which is convenient for use.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
