Description

Technical Field

[0001] The present application relates to the technical field of conductive foam testing equipment, and in particular to a conductive foam heat resistance testing equipment. Background Art

[0002] Conductive foam refers to a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed to the device to be shielded with adhesive tape. Therefore, conductive foam is found on many devices in daily life.

[0003] After the production of conductive foam is completed, the heat resistance of the conductive foam needs to be measured. Usually, the conductive foam is heated to 80°C in a closed box and kept there. Whether the heat resistance is good is judged by observing whether the conductive foam is denatured or damaged. During the heating process of the conductive foam, the conductive foam will produce odor when heated and spread in the box. Most boxes are equipped with ventilation pipes to absorb air in the box. The ventilation pipes of this absorption method have a small absorption coverage range and cannot quickly absorb the air in the box. The deodorization efficiency is low. If the deodorization is not complete, the odor will spread into the air after the box is opened, affecting the laboratory environment. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] Example:

[0033] The present application embodiment discloses a conductive foam heat resistance testing device, referring to Figure 1 and Figure 2, including a chassis 1, on which is installed a sliding door 12 that can slide up and down and stay. The sliding door 12 is a prior art and will not be described in detail in the embodiments of the present application. A heating device 2 for heating conductive foam is installed in the chassis 1, a purification device 3 for purifying air is installed in the chassis 1, a cooling device 4 for cooling the heated conductive foam is installed in the chassis 1, and a drying device 5 for drying the conductive foam is installed in the chassis 1.

[0034] Slide the sliding door 12 upwards, place the conductive foam on the heating device 2 after opening the sliding door 12, slide downwards to close the sliding door 12 to seal the heating device 2 and the conductive foam in the chassis 1, start the heating device 2 to heat the conductive foam to 80°C and observe whether the conductive foam is deformed or damaged. When heating the conductive foam, the purification device 3 absorbs the odor generated by the heat of the conductive foam to reduce the pollution to the air. The tester passes the heated conductive foam through the cooling device 4 to lower the temperature of the conductive foam. After cooling, the tester quickly dries the conductive foam through the drying device 5, which is conducive to improving the convenience of the conductive foam heat resistance test equipment during use.

[0035] The heating device 2 uses an infrared heater 21, and the drying device 5 uses a vacuum dryer 51. In this embodiment, the infrared heater 21 and the vacuum dryer 51 are both existing technologies and will not be described in detail in the embodiments of this application.

[0036] The conductive foam is placed on the infrared heater 21, and the infrared heater 21 can quickly heat the conductive foam to 80° C. The vacuum dryer 51 can quickly dry the conductive foam to a dry state.

In this embodiment, an exhaust fan is connected to the end of the first connecting pipe 331 away from the purification box 32, and activated carbon for removing odor is installed in the purification box 32. A second connecting pipe 332 is fixedly connected to the side wall of the purification box 32 close to the sliding door 12, and the second connecting pipe 332 is connected to the purification box 32. A ventilation device 34 is fixedly connected to the end of the second connecting pipe 332 away from the purification box 32.

[0038] The ventilation device 34 includes a first ventilation box 341, which is fixedly mounted on the inner side wall of the chassis 1, the second connecting pipe 332 is connected to the interior of the first ventilation box 341, the second ventilation box 342 is slidably connected inside the first ventilation box 341, a first sealing strip 3411 is fixedly mounted on one end of the first ventilation box 341 near the second ventilation box 342, and a second sealing strip 3421 is fixedly mounted on one end of the second ventilation box 342 near the first ventilation box 341. A third ventilation box 343 is slidably installed in the second ventilation box 342, a third sealing strip 3422 is fixedly installed on one end of the second ventilation box 342 away from the first ventilation box 341, and a fourth sealing strip 3431 is fixedly installed on one end of the third ventilation box 343 close to the second ventilation box 342.

The ventilation holes 35 connect the interior of the chassis 1 with the first ventilation box 341, the second ventilation box 342 and the third ventilation box 343. The first ventilation box 341, the second ventilation box 342 and the third ventilation box 343 are equally arranged in length and width.

A connecting block 365 is hinged at one end of the connecting rod 364 away from the slider 362. The connecting block 365 is fixedly installed on the inner side wall of the sliding door 12.

[0040] When the sliding door 12 is opened, the sliding door 12 drives the connecting rod 364 to move upward, and the connecting rod 364 pushes the slider 362 to slide on the guide rail 361 toward the first ventilation box 341. The slider 362 drives the connecting plate 363 to move, thereby driving the third ventilation box 343 to slide in the second ventilation box 342 and retract in the second ventilation box 342.

[0041] When it is necessary to close the sliding door 12 to perform heating detection on the conductive foam, pull the sliding door 12 downward to slide, and the sliding door 12 drives the connecting rod 364 to move downward. The connecting rod 364 pulls the slider 362 to slide on the guide rail 361 toward the sliding door 12, and the slider 362 drives the connecting plate 363 to move, thereby pulling the third ventilation box 343 out of the second ventilation box 342, and pulling the second ventilation box 342 out of the first ventilation box 341, so that the third ventilation box 343 and the second ventilation box 342 are laid flat in the chassis 1, increasing the occupied area of ​​the ventilation device 34 in the chassis 1, thereby increasing the gas absorption area of ​​the purification device 3 in the chassis 1, making it easier for the ventilation device 34 to quickly absorb the gas in the chassis 1, which is beneficial to improving the efficiency of the conductive foam heat resistance test device during use.

[0042] Reference Figure 5 The cooling device 4 includes a storage box 41, which is fixedly mounted on the chassis 1. A water pump 42 is fixedly mounted on the chassis 1 near the storage box 41. The water suction pipe of the water pump 42 is connected to the inside of the storage box 41. The water outlet pipe of the water pump 42 is connected to a third connecting pipe 43.

A storage tank 45 is provided on the mounting table where the drying device 5 is mounted in the chassis 1. A water outlet hole 46 is provided in the storage tank 45 provided on the chassis 1. A piston 47 for blocking the water outlet hole 46 is installed on the chassis 1. A fourth connecting pipe 48 without drainage is buried in the chassis 1. The fourth connecting pipe 48 is connected to the water outlet hole 46. In this embodiment, the cooling water stored in the storage box 41 is ultrapure water.

[0043] When the conductive foam heating test is completed, open the faucet 44, and let the cooling water flow into the storage tank 45 through the water pump 42. The conductive foam after heating is placed in the cooling water, and rinsed and cooled by the cooling water. After the cooling water is used up, pull out the piston 47, and discharge the used cooling water from the fourth connecting pipe 48, which is beneficial to improve the efficiency of the conductive foam heat resistance test equipment during use.

[0044] The implementation principle of the embodiment of the present application is: put the conductive foam into the infrared heater 21, close the sliding door 12, and increase the gas absorption range of the purification device 3 by adjusting the area of ​​the ventilation device 34 by pulling the slider 362, so as to quickly absorb the odor generated by the conductive foam during the heating process, start the heating device 2 to heat the conductive foam to 80°C and observe whether the conductive foam is deformed or damaged.
