Description

Technical Field

[0001] This utility model relates to the field of electronic paste testing technology, specifically to an electronic paste constant temperature testing device. Background Technology

[0002] Electronic paste is a basic material for manufacturing thick-film components. It is a paste-like substance made by uniformly mixing solid powder and organic solvent through three-roll milling. The production and use of electronic paste requires constant temperature testing. Existing constant temperature testing devices usually insert the temperature sensor directly into the electronic paste to detect the temperature. After the temperature detection device detects the electronic paste, the electronic paste will adhere to the surface of the temperature sensor. As more and more paste adheres, the probe's temperature sensing decreases, which seriously affects the probe's temperature measurement.

[0003] However, existing temperature detection devices have the problem of inconvenience in removing the electronic paste adhering to the surface of the temperature sensor. Therefore, in order to facilitate the cleaning of electronic paste on the surface of the temperature sensor, some technologies have proposed related structures to assist in the cleaning of electronic paste on the surface of the temperature sensor. For example, a utility model patent with publication number CN215178260U proposes an electronic paste constant temperature testing device. The temperature sensor is drawn into the fixed tube by a first scraping device, so that the electronic paste adhering to the side of the temperature sensor is scraped off at the opening of the inner hole, which facilitates the removal of electronic paste on the side of the temperature sensor. By rotating the cover, the scraper scrapes off the electronic paste on the end face of the temperature sensor, which facilitates the removal of electronic paste adhering to the end face of the temperature sensor.

[0004] Theoretically, the implementation of the aforementioned technical structure is beneficial for cleaning the electronic paste adhering to the surface of the temperature sensor. However, according to the description in the aforementioned technical content, the scraper used to remove the electronic paste is fixedly connected to the movable block. With this fixed connection, when the scraper is damaged, it is inconvenient for the operator to remove the worn scraper from the movable block. As the wear of the scraper increases, residues will remain after the scraper cleans the electronic paste on the temperature sensor, thus affecting the effectiveness of the scraper in cleaning the electronic paste on the temperature sensor.

[0033] The movable component 21 consists of a ball nut 211 and a ball screw 212. The inner wall of the ball nut 211 is threadedly connected to the inner wall of the ball screw 212.

[0034] Working Principle: In use, firstly, when the temperature sensor 1 is in use, remove the cover 16 from the housing 2. The temperature sensor 1 needs to extend from the inside of the housing 2. Turn on the power to the rotary motor 23. After the rotary motor 23 is turned on, it drives the ball screw 212 to rotate via the shaft 22. Due to the threaded connection between the ball screw 212 and the ball nut 211, the ball screw 212 rotates circumferentially while simultaneously driving the ball nut 211 to move horizontally. Simultaneously, the ball nut 211 moves, driving the annular block 17 to move in the same direction via the extension rod 18 above. Simultaneously, the annular block 17 moves, driving the temperature sensor 1 to move via the fastening bolt 10. Continue until the temperature sensor 1 is extended outside the housing 2, then turn off the power to the rotary motor 23. At this point, the movement of the temperature sensor 1 simultaneously drives the limiting ring 24 to move outside the limiting rod 26. The ball 25 is positioned between the limiting ring 24 and the limiting rod 26, causing the ball 25 to roll on the limiting rod 26, thereby reinforcing the temperature sensor 1 within the housing. 2. Stability of internal and external telescopic movement. Then, after use, retract the temperature sensor 1 into the housing 2, and turn on the power of the rotary motor 23. The turning on of the rotary motor 23 drives the movement of the moving component 21, causing the temperature sensor 1 to retract into the housing 2. Due to the threaded connection between the threaded column 8 and the mounting plate 9, the threaded column 8 can achieve linear movement while rotating circumferentially, until the first scraper 3 contacts the outer wall of the temperature sensor 1, and the slurry on the temperature sensor 1 contacts the first scraper 3. Then, scrape off the slurry on the surface of temperature sensor 1, and then move the second scraper 4 vertically by pressing the lifting rod 27. At this time, the first spring 28 is compressed, and the second scraper 4 removes the slurry on the left end of temperature sensor 1 from top to bottom. Finally, when the first scraper 3 and the second scraper 4 are worn, pull out the positioning rod 701 connecting the locking block 5 and the fixing block 6. At this time, the spring 702 is in a stretched state, and the first scraper 3 or the second scraper 4 can be removed to replace the first scraper 3 or the second scraper 4.
