Description

Technical Field

[0001] This utility model relates to the field of industrial packaging technology, specifically to a packaging structure for a constant current device. Background Technology

[0002] A constant current device is an electronic component that can achieve constant current output. It can output a constant current value within a certain power supply voltage range. Such devices are widely used in LED driving, battery charging and discharging, semiconductor device parameter testing and electronic circuit interface. Common constant current devices include constant current diodes and constant current transistors. These devices usually have a two-terminal or three-terminal structure. As semiconductor components, they achieve constant current output through internal mechanisms.

[0003] In existing constant current diode packaging, epoxy resin, hardener, and filler are mixed evenly in a predetermined ratio. The cleaned and dried constant current diode is placed in a pre-packaging mold, and the mixed epoxy resin, after degassing treatment, is poured into the packaging mold until it completely covers the constant current diode. After filling, the packaging mold is placed in a constant temperature and humidity equipment for curing. Existing packaging methods involve individual packaging or mass packaging, followed by cutting and separating after curing. This process is time-consuming and labor-intensive. Individual packaging is not easy to arrange and combine, and tends to occupy too much space. When mass packaging is carried out simultaneously, epoxy resin is prone to quality problems such as bubbles and white spots, which affect the appearance and performance of the packaged components. Therefore, we propose a novel packaging structure for constant current devices to solve the above problems. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This application provides a packaging structure for a constant current device, which solves the problems of existing packaging methods that involve individually packaging or mass packaging, followed by curing and then cutting, which are time-consuming and labor-intensive, difficult to arrange and combine individually, and prone to occupying too much space. When packaging in large quantities at the same time, epoxy resin is prone to quality problems such as bubbles and white spots, which affect the appearance and performance of the packaged parts.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a packaging structure for a constant current device.

[0025] According to the appendix Figure 1-5 As shown, it includes a body 1, a package 2 is provided in the middle of the body 1, and a rotating mechanism 3 is provided in the middle of the body 1.

[0026] The rotating mechanism 3 includes a push rod 302, a rotating cylinder 303, a slider 304, and a slide groove 305;

[0027] When the device is in use, the hydraulic rod moves downward, causing the encapsulator 2 to move downward. The fixing block 301 and the support plate 306 also move downward. The support plate 306 pushes the push rod 302 downward, causing the rotating drum 303 to rotate. The slider 304 at the bottom of the push rod 302 slides inside the groove 305. The one-way transmission component 4 at the bottom of the rotating drum 303 drives the second gear 402 to rotate. The second gear 402 drives the first gear 401 to rotate, causing the turntable 5 to rotate. The encapsulator 2 injects the epoxy resin mixture into the holes at the top of the turntable 5. After all the holes are filled, the encapsulator is removed, and the fixing strip 6 at the bottom of the new turntable 5 is inserted into the fixing hole 7 of the first gear 401, completing the quick replacement of the turntable 5.

[0028] The push rod 302 is fixedly installed on one side of the encapsulator 2, the rotating cylinder 303 is movably sleeved on the outer surface of the push rod 302, the slide groove 305 is opened inside the rotating cylinder 303, and the slider 304 is fixedly installed on one side of the push rod 302 and slides inside the slide groove 305.

[0029] The bottom of the drum 303 is provided with a one-way transmission component 4, and the middle of the machine body 1 is provided with a turntable 5. The drum 303 is connected to the turntable 5 through the one-way transmission component 4.

[0030] A fixing block 301 is fixedly connected to the top of the encapsulator 2, and a support plate 306 is fixedly installed on one side of the fixing block 301. The support plate 306 is fixedly connected to the push rod 302.

[0031] A rotating shaft 405 is fixedly installed at the bottom of the rotating cylinder 303. A pawl 404 is provided at the top of the rotating shaft 405. A ratchet 403 is rotatably connected to the outer surface of the rotating shaft 405. The pawl 404 and the ratchet 403 are movably engaged. The top of the rotating shaft 405 has a slot, and the pawl 404 is movably connected in the slot. When the encapsulator 2 moves downward, the rotating cylinder 303 rotates clockwise, driving the one-way transmission component 4 to rotate. The one-way transmission component 4 drives the second gear 402 to rotate, finally realizing the rotation of the turntable 5. When the encapsulator 2 moves upward, the rotating cylinder 303 rotates counterclockwise. The pawl 404 inside the one-way transmission component 4 retracts into the slot of the rotating shaft 405, and the ratchet 403 cannot rotate, so that when the encapsulator 2 moves upward, the turntable 5 will not reverse.

[0032] The first gear 401 and the second gear 402 are rotatably connected in the middle of the body 1. The first gear 401 and the second gear 402 are movably engaged. The bottom of the ratchet 403 is fixedly connected to the top of the second gear 402. A rotating shaft is installed at the bottom of the first gear 401 and the second gear 402, and the first gear 401 and the second gear 402 rotate on their outer surfaces.

[0033] The top of the first gear 401 has a fixing hole 6, and the bottom of the turntable 5 is fixedly installed with a fixing strip 7. The fixing strip 7 is movably inserted into the inside of the fixing hole 6. Through the combination of the fixing hole 7 and the fixing strip 6, the turntable 5 can be quickly replaced, while avoiding the turntable 5 from slipping and affecting the packaging.
