[0038] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as a limitation on the utility model.
[0039] As Figures 1 to 5As shown, the embodiment provides an aging test device, which comprises a test piece 100, a circulation pipeline 200, a fan 400, an air inlet valve mechanism 300 and an air outlet valve mechanism 500. The test piece 100 has an aging cavity for aging test of a workpiece. The circulation pipeline 200 has a circulating air duct 210, an air inlet and an air outlet which are in communication with the circulating air duct 210, and the air inlet and the air outlet are in communication with the aging cavity. The circulation pipeline 200 further has a first air port and a second air port which are in communication with the circulating air duct 210. The fan 400 is connected in series in the circulating air duct 210. The first air port is located between the air inlet and the fan 400. The second air port is located between the fan 400 and the air outlet. The air inlet valve mechanism 300 is arranged at the first air port of the circulation pipeline 200 and can close or open the first air port. The air outlet valve mechanism 500 is arranged at the second air port of the circulation pipeline 200 and can close or open the second air port. The outlet of the air outlet valve mechanism 500 can be in communication with a waste gas pipeline.
[0040] The fan 400 and the circulation pipeline 200 cooperate to make the gas in the aging cavity circulate normally, so as to adjust the gas temperature in the aging cavity. When the first air port and the second air port are both opened, on the basis of the gas circulation in the aging cavity, part of outdoor gas can enter the circulating air duct 210 through the first air port, and part of the gas in the circulating air duct 210 can flow into the waste gas pipeline through the outlet of the air outlet valve mechanism 500 for treatment, so that the harmful gas in the aging cavity is orderly and safely discharged without affecting the gas circulation in the aging cavity, and the problem that the harmful gas diffuses to the workshop to cause a serious threat to personal safety when the chip is taken out after the test is solved.
[0041] In combination with Figure 2 and Figure 3 As shown, the air inlet valve mechanism 300 comprises a first valve body 310 and a first plugging assembly 320. The first valve body 310 has a first channel 311. The first plugging assembly 320 is in rotary cooperation with the first valve body 310 and can plug or open the first channel 311 in the rotary process. The rotary cooperation is convenient for driving and occupies less space.
[0042] The air inlet valve mechanism 300 also includes two stop members 330, both disposed within the first channel 311. The two stop members 330 are spaced apart along the extension direction of the first channel 311 and also spaced apart radially along the first channel 311. The first sealing assembly 320 includes a first shaft 321 and two first sealing plates 322. The first shaft 321 is rotatably disposed on the first valve body 310. In the extension direction of the first channel 311, the first shaft 321 is located between the two stop members 330. In the radial direction of the first channel 311, the first shaft 321 is located between the two stop members 330. The two first sealing plates 322 are both disposed on the first shaft 321 and are symmetrically arranged about the axis of the first shaft 321. When the first shaft 321 rotates, the two first sealing plates 322 abut against the two corresponding stop members 330 respectively to seal the first channel 311, or separate from the two corresponding stop members 330 respectively to open the first channel 311. The first channel 311 can be cylindrical or rectangular. When the first channel 311 is rectangular (e.g., ...), Figure 3 As shown in the diagram, the radial direction of the first channel 311 refers to the height direction of the first channel 311, which is perpendicular to the extension direction of the first channel 311. This structure, on the one hand, limits the position of the first sealing plate 322, ensuring the extreme position during rotation; on the other hand, the two first sealing plates 322 are both mounted on the first shaft 321 and are symmetrical, which helps to reduce the driving force.
[0043] To improve sealing performance, in some embodiments, the air inlet valve mechanism 300 further includes two first sealing gaskets 340, which are respectively disposed on two stop members 330. When the first channel 311 is blocked, the two first sealing gaskets 340 are respectively sandwiched between the corresponding stop member 330 and the first sealing piece 322. The first sealing gaskets 340 have a U-shaped structure, and the openings of the two first sealing gaskets 340 are arranged opposite to each other. The first sealing gaskets 340 are connected to the stop members 330 by screwing or bonding. The first sealing gaskets 340 are made of rubber.
[0044] The air inlet valve mechanism 300 also includes a drive component 360, which is located on the first valve body 310. The first sealing component 320 is connected to the output end of the drive component 360 to achieve automatic sealing of the first channel 311 by the first sealing component 320, thereby improving operating efficiency and enhancing the user experience. The drive component 360 can be a servo motor or a rotary cylinder.
[0045] Due to the gas entering from the air inlet valve mechanism 300, eventually part of the gas will enter the aging chamber. In order to ensure the quality of the gas entering the aging chamber, in some embodiments, the air inlet valve mechanism 300 further comprises a filter 350, which is arranged on the first valve body 310 and located at the inlet of the first channel 311. The filter 350 can be directly prepared by using the existing technology.
[0046] In some embodiments, in combination with Figure 4 and Figure 5 As shown in the drawings, the air outlet valve mechanism 500 comprises a second valve body 510 and a second blocking assembly 520. The second valve body 510 has a second channel 514, and the outlet of the second channel 514 can be communicated with the exhaust pipeline. The second blocking assembly 520 is rotationally connected with the second valve body 510 and can block or open the second channel 514 during rotation. When the second blocking assembly 520 opens the second channel 514, part of the second blocking assembly 520 is located in the circulating air duct 210, so as to guide part of the air flow in the circulating air duct 210 to the second channel 514. The rotational arrangement of the second blocking assembly 520 helps to reduce the floor area and facilitate driving. In addition, when the second channel 514 is opened, part of the second blocking assembly 520 is located in the circulating air duct 210, so that part of the air flow in the circulating air duct 210 can be guided to the second channel 514 and then discharged to the exhaust pipeline, thereby effectively improving the air exchange effect in the aging chamber.
[0047] The second valve body 510 comprises a wind guide cylinder 511, a blocking base 512 and a second sealing gasket 513. The blocking base 512 is arranged on the circulating pipeline 200, the wind guide cylinder 511 is arranged on the blocking base 512, and the second sealing gasket 513 is arranged on the blocking base 512 and located inside the wind guide cylinder 511. The blocking base 512 has a first blocking hole, and the second sealing gasket 513 has a second blocking hole. In the gas flow direction, the circulating air duct 210, the second air port, the first blocking hole, the second blocking hole and the wind guide cylinder 511 are sequentially communicated, and the second blocking assembly 520 can block the second blocking hole. The scheme of blocking the second blocking hole in the second sealing gasket 513 helps to improve the sealing effect while blocking the second channel 514. The second sealing gasket 513 is connected with the blocking base 512 by screwing and / or bonding. The second sealing gasket 513 is made of rubber material.
[0048] The second blocking assembly 520 comprises a second shaft 521 and two second blocking sheets 522, the second shaft 521 is rotationally arranged on the second valve body 510, and the second shaft 521 is close to the downstream side wall of the second blocking hole along the air flow direction in the circulating air duct 210; the two second blocking sheets 522 are both fixed on the second shaft 521, among the two second blocking sheets 522, the upstream second blocking sheet 522 can abut against the lower side of the second sealing gasket 513, and the downstream second blocking sheet 522 can abut against the upper side of the second sealing gasket 513, when the second channel 514 is opened, the downstream second blocking sheet 522 is located in the air duct 511, and the upstream second blocking sheet 522 is partially located in the circulating air duct 210, the upstream second blocking sheet 522 can intercept the gas flowing in the circulating air duct 210 and guide the intercepted air flow into the air duct 511, and the air exchange effect is improved.
[0049] Since the second blocking sheet 522 plays a role of interception and flow guiding, in order to avoid deformation of the second blocking sheet 522 to affect the flow guiding effect, in some embodiments, in order to improve the strength of the second blocking sheet 522, the second blocking sheet 522 comprises a blocking body 5221 and a reinforcing rib 5222 arranged on the blocking body 5221, and the extending direction of the reinforcing rib 5222 is perpendicular to the axis of the second shaft 521. The reinforcing rib 5222 of this structure not only enhances the strength of the second blocking sheet 522, but also helps to guide the air flow and improve the smoothness of the gas flowing into the air duct 511.
[0050] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not the limitation of the embodiments of the utility model. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, all the embodiments are not enumerated.
