Description

Technical Field

[0002] Low-temperature sintered silver, as a typical high-temperature resistant encapsulation material, can achieve encapsulation interconnection at low temperatures (200°C-300°C) and maintain stable operation for extended periods at high temperatures (theoretically up to 700°C), thus attracting widespread attention. The sintering temperature of silver paste is 180-250°C. A sintering neck is formed through interparticle atomic diffusion, followed by densification through volume shrinkage to form a sintered body. Metallurgical connections are formed between silver particles and the interface through interdiffusion, resulting in excellent mechanical properties. The sintered body exhibits good thermal and electrical conductivity and high-temperature stability, meeting the requirements for low-temperature interconnection and high-temperature operation of power semiconductor devices such as SiC.

[0003] For the healthy and sustainable development of my country's high-power electronics and other industries, it is imperative to achieve the localization of high thermal conductivity and high reliability sintered silver paste. This requires conductive paste manufacturers to continuously optimize the formulation of sintered silver paste, while also achieving optimal design for key raw materials such as silver powder and resin.

[0004] In the prior art, conductive paste after production needs to be tested for conductivity. However, existing conductive paste testing devices cannot uniformly test the conductive paste during use, resulting in low accuracy and affecting its use. Therefore, a conductive paste testing device is proposed to solve the problems mentioned above. Utility Model Content

It solves the problems of existing conductive paste detection devices being unable to uniformly detect conductive paste during use, having low detection accuracy, and affecting their use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conductive slurry detection device, comprising a support, a tank fixedly mounted on the top of the support, a first conductive plate and a second conductive plate fixedly mounted inside the tank, an interface provided on the outer side of the first conductive plate, an indicator light provided on the outer side of the second conductive plate, and a stirring mechanism provided inside the tank;

[0009] Furthermore, the interface is located on the outer wall of the tank, and a mounting plate is fixedly connected to the side of the tank away from the interface. The indicator light is fixedly installed on the outside of the mounting plate.

[0010] Furthermore, the sealing shell is fixedly installed on the inner top wall of the tank, the upper end of the mounting rod is rotatably connected to the inner top wall of the tank, and the outer wall of the sleeve is connected to the sealing shell through a bearing.

[0011] Furthermore, a first gear is fixedly installed on the outer wall of the shaft, and a second gear is fixedly installed on the outer wall of the mounting rod, with the first gear and the second gear meshing together.

[0015] Beneficial effects:

When the conductive slurry is inside the tank, it contacts the first and second conductive plates inside the tank. The current on the first conductive plate can be transferred to the second conductive plate through the qualified conductive slurry, causing the indicator light to illuminate for easy detection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1 to 3 The conductive slurry detection device in this embodiment includes a bracket 1, a tank 2 fixedly installed on the top of the bracket 1, a feed pipe 3 fixedly connected to the top of the tank 2, and a discharge pipe 4 fixedly connected to the bottom of the tank 2.

[0024] In this embodiment, a stirring mechanism is provided inside the tank 2. The stirring mechanism includes a sealing shell 9, which is fixedly installed on the inner top wall of the tank 2. A drive motor 10 is fixedly installed inside the sealing shell 9. A shaft 11 is fixedly installed on the output shaft of the drive motor 10. A first blade 12 is fixedly connected to the outer wall of the shaft 11. A sleeve 19 is also sleeved on the outer side of the shaft 11. The outer wall of the sleeve 19 is connected to the sealing shell 9 through a bearing. A second blade 20 is fixedly connected to the outer wall of the sleeve 19. An installation rod 15 is drivenly connected to the outer side of the shaft 11. The installation rod 15 is drivenly connected to the sleeve 19. The upper end of the installation rod 15 is rotatably connected to the inner top wall of the tank 2.

[0025] The first gear 13 is fixedly installed on the outer wall of the shaft 11, the second gear 14 is fixedly installed on the outer wall of the mounting rod 15, the first gear 13 and the second gear 14 are meshed, the third gear 16 is fixedly installed at the lower end of the mounting rod 15, the fourth gear 17 is rotatably installed on the inner wall of the sealing shell 9, and the fifth gear 18 is fixedly installed on the outer wall of the sleeve 19. The fourth gear 17 is located between the third gear 16 and the fifth gear 18, and the two sides of the fourth gear 17 are respectively meshed with the third gear 16 and the fifth gear 18. By starting the drive motor 10, the shaft 11 rotates, which in turn drives the first blade 12 to rotate. Simultaneously, the first gear 13 rotates, which in turn drives the second gear 14 to rotate. The second gear 14 then drives the mounting rod 15 to rotate, which in turn drives the third gear 16 to rotate. The third gear 16 then drives the fifth gear 18 to rotate via the fourth gear 17, which in turn drives the sleeve 19 to rotate, and consequently drives the second blade 20 to rotate. According to the gear transmission principle, the shaft 11 and the sleeve 19 rotate in opposite directions, which makes the first blade 12 and the second blade 20 rotate in opposite directions, thus achieving bidirectional stirring of the conductive slurry inside the tank 2, resulting in high stirring efficiency.

[0026] Example 2:

[0027] Please see Figure 1 Based on Embodiment 1, a first conductive plate 5 and a second conductive plate 6 are fixedly installed inside the tank body 2. An interface 7 is provided on the outer side of the first conductive plate 5, and an indicator light 8 is provided on the outer side of the second conductive plate 6. The interface 7 is located on the outer wall of the tank body 2. A mounting plate is fixedly connected to the side of the tank body 2 away from the interface 7, and the indicator light 8 is fixedly installed on the outer side of the mounting plate.

[0028] The working principle of the above embodiments is as follows:

[0029] In use, the first conductive plate 5 is connected to an external power source via interface 7. When the conductive slurry is inside the tank 2, it contacts the first conductive plate 5 and the second conductive plate 6 inside the tank 2. The current on the first conductive plate 5 can be transmitted to the second conductive plate 6 through the qualified conductive slurry, causing the indicator light 8 to illuminate for easy detection. During the detection process, the drive motor 10 is started to rotate the shaft 11, which in turn rotates the first blade 12, and simultaneously rotates the first gear 13 and the second gear 14. The second gear 14 then rotates the mounting rod 15, which in turn rotates the third gear 16. The third gear 16 then rotates the fifth gear 18 via the fourth gear 17, which in turn rotates the sleeve 19, which in turn rotates the second blade 20. The cooperation of the first blade 12 and the second blade 20 efficiently stirs the conductive slurry inside the tank 2, ensuring uniform contact with the first conductive plate 5 and the second conductive plate 6 for easy and uniform detection.
