Description

Technical Field

[0001] The utility model relates to the technical field of sealant detection equipment, in particular to a high and low temperature and humidity test chamber for sealant. Background Technique

[0002] A sealant is a sealing material that deforms with the shape of the sealing surface, does not easily flow, and has a certain adhesiveness. Its main function is to fill the configuration gap, achieve a sealing effect, and has multiple functions such as anti-leakage, waterproof, anti-vibration, sound insulation, and heat insulation. After the sealant is produced, its performance needs to be detected. The high and low temperature and humidity test chamber can simulate various environments and then detect the sealant.

[0003] Although the existing high and low temperature and humidity test chambers can detect sealants, their accuracy in detecting the bonding strength of sealants in various environments is still insufficient, which reduces the stability of the equipment in detecting the actual performance of sealants. Therefore, there is an urgent need for a high and low temperature and humidity test chamber for sealants to solve the above existing problems. Content of the Utility Model

Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention: a high and low temperature and humidity test chamber for sealant, including a detecting box body 10 for support. A sealing door 7 is hinged to the front end face of the detecting box body 10 through a hinge. A bidirectional lead screw 8 is rotatably clamped to the inner end face of the detecting box body 10 near the bottom, and a servo motor 9 is arranged on the side end face of the detecting box body 10 opposite to the bidirectional lead screw 8.

[0023] The detecting device 6 has two groups in total, and the two groups of detecting devices 6 are threadedly slidably connected inside the detecting box body 10 through the bidirectional lead screw 8;

[0024] The heating box body 1 is fixedly arranged on the rear end face of the detecting box body 10, and nine groups of fans 11 are equidistantly arranged on the rear end face of the detecting box body 10 where it is in contact with the heating box body 1;

[0025] The atomizing device 2 is rotatably clamped to the upper end face of the detecting box body 10 near the middle. A driving synchronous pulley 4 is rotatably clamped to the upper end face of the detecting box body 10 near the atomizing device 2, and the atomizing device 2 is meshed and connected with the driving synchronous pulley 4 through a synchronous belt 5. A stepping motor 3 is arranged on the upper end face of the detecting box body 10 opposite to the driving synchronous pulley 4.

[0026] The atomizing device 2 includes a driven synchronous pulley 21. An infusion tube 22 is fixedly arranged on the inner end face of the driven synchronous pulley 21, and an atomizing nozzle 23 is fixedly installed at the bottom end face of the infusion tube 22.

[0027] The detecting device 6 includes a ball slide block 63. A tension sensor 62 for detection is arranged on the upper end face of the ball slide block 63, and a bonding card board 61 is arranged on the inner end face of the tension sensor 62.

[0028] Nine groups of air guide holes are equidistantly arranged on the rear end face of the detection box body 10 and penetrate to the outside, and the air guide holes are directly opposite to the fan 11. The air guide holes can provide a sufficient guiding basis for the fan 11, facilitating the subsequent rapid introduction of hot and cold air by the fan 11.

[0029] Two guide shafts are arranged inside the detection box body 10 near the bidirectional lead screw 8. The ball slide block 63 is threadedly slidably connected to the outside of the guide shaft through the bidirectional lead screw 8. The guide shaft can provide a sufficient linear guiding basis for the detection device 6, improving the stability of the detection device 6 during displacement inside the detection box body 10.

[0030] The driven synchronous pulley 21 is meshed and connected to the driving synchronous pulley 4 through the synchronous belt 5. The stepping motor 3 can drive the driven synchronous pulley 21 to rotate at a high speed through the driving synchronous pulley 4 and the synchronous belt 5, thereby facilitating the subsequent uniform output of atomized gas by the atomizing nozzle 23 and improving the humidity uniformity inside the detection box body 10.

[0031] Working principle: When detecting the sealant, the user can apply the sealant to be detected inside the two bonding clamping plates 61. After coating, close the sealing door 7. At this time, start the servo motor 9. The servo motor 9 can drive the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 can then drive the two ball slide blocks 63 to move centripetally through the threaded connection with the two ball slide blocks 63, so that the two bonding clamping plates 61 coated with the sealant can be closed until adhesion is completed. When detecting the sealant in various environments, the heating box body 1 can perform heating operations, and multiple fans 11 can introduce the heated air into the detection box body 10 to detect the high-temperature state. At the same time, when the heating box body 1 is not heating, the fan 11 can quickly cool the inside of the detection box body 10 to simulate a low-temperature environment. At the same time, the external liquid supply pipe can introduce the liquid into the atomizing nozzle 23 through the infusion pipe 22. Subsequently, the stepping motor 3 can drive the driven synchronous pulley 21 to rotate at a high speed through the driving synchronous pulley 4 and the synchronous belt 5. The driven synchronous pulley 21 can drive the atomizing nozzle 23 to atomize the liquid, facilitating the creation of different humidity states in cooperation with low and high temperatures. At the same time, when detecting in different environments, the servo motor 9 can drive the two ball slide blocks 63 to move in the reverse direction through the bidirectional lead screw 8, so that the two bonding clamping plates 61 can be pulled in opposite directions, and the tension sensor 62 can detect the tension generated when the sealant is separated.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
