Description

Technical Field

[0001] The utility model belongs to the technical field of leakage testing equipment, and specifically relates to an inverter leakage testing device and leakage testing equipment. Background Art

[0002] An inverter is a converter that converts DC power into constant frequency and voltage or frequency and voltage regulated AC power. To prevent water from entering the inverter, the inverter cover needs to be tested for leaks, i.e., sealing tests, during the manufacturing process. Only covers that pass the test can flow into the assembly process. An installation cavity is formed inside the cover, and the installation cavity has an opening. The opening needs to be sealed during the leak test.

[0003] In the related art, during the leak test, the cover is placed on the sealing plate so that the opening of the cover contacts the sealing plate, and the center of the cover is pressed by a pressing mechanism so that the opening of the installation cavity is sealed and connected with the sealing plate. However, on the one hand, the pressing mechanism is pressed on the center of the cover, so that the force on the cover is relatively concentrated; on the other hand, in order to ensure the sealing between the opening of the installation cavity and the sealing plate, the pressing mechanism needs to apply a larger pressing force, so that the force on the cover is relatively concentrated and the pressing force is relatively large, causing the cover to be more easily damaged during the leak test, and thus resulting in a higher scrap rate of the cover.

The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] Please see attached Figures 1 to 4 The inverter leakage testing device of the utility model includes a sealing assembly 100 and a pressing mechanism 200 .

[0036] The sealing assembly 100 is used to place the cover body 20, and the pressing mechanism 200 includes a pressing drive assembly 210, a connecting plate 220 and a pressing assembly 230. The connecting plate 220 is fixedly connected to the power output end of the pressing drive assembly 210. The pressing assembly 230 includes a pressing rod 231, an anti-loosening elastic member 232, a pressure regulating member 233 and an elastic abutting member 234. The first end of the pressing rod 231 is fixedly connected to the connecting plate 220, and the pressing rod 231 is vertically extended. The second end is provided with a connection hole 2311, which is a threaded hole. The anti-loosening elastic member 232 is located in the connection hole 2311 and connected to the pressure rod 231. The first end of the pressure regulating member 233 is located in the connection hole 2311 and is threadedly connected to the pressure rod 231, so that the position of the pressure regulating member 233 in the connection hole 2311 can be adjusted. The first end of the pressure regulating member 233 also abuts against the anti-loosening elastic member 232, so that the elastic force of the anti-loosening elastic member 232 acts on the pressure regulating member 233. The elastic abutment member 234 is an elastic structure, and the elastic abutment member 234 covers and connects to the second end of the pressure regulating member 233. There are multiple pressing assemblies 230, and the elastic abutment members 234 of the multiple pressing assemblies 230 are used to surround the cover body 20 and press the periphery of the cover body 20 against the sealing assembly 100, so that the opening of the cover body 20 is sealed and connected to the sealing assembly 100.

[0037] In this embodiment, when leak testing is performed, the downward pressure driving assembly 210 drives the connecting plate 220 and the pressing assembly 230 to move downward, so that the elastic abutment members 234 of each pressing assembly 230 abut against the upper side of the periphery of the cover body 20, thereby making the opening of the cover body 20 sealed and connected with the sealing assembly 100, and at this time, the elastic abutment members 234 elastically abut against the periphery of the cover body 20. When the pressure on the cover body 20 is not enough to achieve sealing at the opening, the pressure regulating member 233 is rotated before leak testing to increase the extension length of the pressure regulating member 233, so that the pressure acting on the cover body 20 by the elastic abutment member 234 is increased, thereby sealing the opening of the cover body 20. When the cover body 20 is damaged due to excessive pressure, the pressure regulating member 233 is rotated before leak testing to shorten the extension length of the pressure regulating member 233, so that the pressure acting on the cover body 20 by the elastic abutment member 234 is reduced, thereby preventing the cover body 20 from being damaged due to excessive pressure.

[0038] The inverter leak test device provided by the utility model has a plurality of clamping assemblies 230 surrounding the cover body 20 and pressing the periphery of the cover body 20 against the sealing assembly 100, so that the pressure of the clamping mechanism 200 is dispersed at the periphery of the cover body 20, thereby avoiding concentrated pressure on the cover body 20, reducing the probability of damage to the cover body 20 during leak test, and further reducing the scrap rate of the cover body 20.

[0039] Furthermore, by rotating the pressure adjusting member 233 to adjust the extension length of the pressure adjusting member 233, and then adjusting the pressure of the elastic abutment member 234 on the cover body 20, the clamping mechanism 200 can adapt to the cover body 20 with different thicknesses at the periphery, thereby improving the adaptability of the clamping mechanism 200.

[0040] Furthermore, the first end of the pressure regulating member 233 abuts against the anti-loosening elastic member 232, so that the elastic force of the anti-loosening elastic member 232 acts on the pressure regulating member 233, thereby suppressing the loosening of the pressure regulating member 233, improving the position stability of the pressure regulating member 233, and improving the stability of the pressure exerted by the elastic abutting member 234 on the cover body 20, thereby improving the sealing stability at the opening of the cover body 20.

[0041] In some preferred embodiments, the second end of the pressure regulating member 233 protrudes from the outside of the first end of the pressure regulating member 233 , the elastic abutting member 234 is a silicone structure, and the anti-loosening elastic member 232 is a spring.

[0042] Embodiment 2:

[0044] The inverter leakage test device of this embodiment also includes a mounting frame 300, which includes a bearing plate 310, a connecting column 320 and a mounting plate 330. The two ends of the connecting column 320 are fixedly connected to the bearing plate 310 and the mounting plate 330 respectively. The mounting plate 330 is located on the upper side of the bearing plate 310. A leakage test area 301 is formed between the mounting plate 330 and the bearing plate 310. The sealing assembly 100 is located in the leakage test area 301 and connected to the bearing plate 310. The pressing mechanism 200 and the sealing assembly 100 are arranged correspondingly up and down. In this embodiment, the pressing drive member is installed on the upper side of the sealing assembly 100 through the mounting plate 330, which improves the convenience of the pressing mechanism 200 pressing the cover body 20.

[0045] In some preferred embodiments, the sealing assembly 100 is slidably connected to the supporting plate 310. During a leak test, the sealing assembly 100 is slid into the leak test area 301. After the leak test is completed, the sealing assembly 100 is slid out of the leak test area 301, thereby preventing the connecting column 320 from interfering with the removal and placement of the cover body 20, thereby improving the convenience of removing and placing the cover body 20.

[0046] Furthermore, the sealing assembly 100 includes a sealing plate 110 and a slider 120, wherein the sealing plate 110 is used to carry the cover body 20, and the slider 120 is fixedly connected to the side of the sealing plate 110 away from the clamping mechanism 200. The mounting frame 300 also includes a guide rail 340, which is fixedly connected to the bearing plate 310, and the slider 120 is slidably connected to the guide rail 340. The slider 120 is guided by the guide rail 340, thereby improving the movement accuracy of the sealing plate 110 and ensuring that the sealing plate 110 can move the cover body 20 to the leak test position.

[0047] In some preferred embodiments, the sealing assembly 100 also includes a feeding drive component, which is installed on the supporting plate 310. The power output end of the feeding drive component is connected to the sealing plate 110. The sealing plate 110 is driven to move by the feeding drive component, thereby improving the convenience of moving the sealing plate 110.

[0048] In some preferred embodiments, the sealing assembly 100 further includes a moving handle 130, which is fixedly connected to the periphery of the sealing plate 110. In this embodiment, when the feeding drive member is damaged, the sealing plate 110 can be moved by the moving handle 130, which improves the convenience of moving the sealing plate 110.

[0049] In some preferred embodiments, the connecting plate 220 is slidably connected to the connecting column 320, so that the connecting column 320 guides the movement of the connecting plate 220, thereby improving the movement accuracy of the connecting plate 220 and the clamping assembly 230, thereby ensuring that the clamping assembly 230 can clamp the periphery of the cover body 20.

[0054] Furthermore, by rotating the pressure regulating member to adjust the extension length of the pressure regulating member, and then adjusting the pressure of the elastic abutment member on the cover body, the clamping mechanism can adapt to the cover body with different thicknesses at the periphery, thereby improving the adaptability of the clamping mechanism.

[0055] Furthermore, the first end of the pressure regulating member abuts against the anti-loosening elastic member, so that the elastic force of the anti-loosening elastic member acts on the pressure regulating member, thereby suppressing the loosening of the pressure regulating member, improving the position stability of the pressure regulating member, and improving the stability of the pressure exerted by the elastic abutting member on the cover body, thereby improving the sealing stability at the opening of the cover body.
