Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to packaging equipment for a gas sensor. Background Art

[0002] A gas sensor is an important sensor capable of performing gas analysis and detection. This device can sense specific gases and determine their concentrations. The most common types are resistive gas sensors, capacitive gas sensors, and resonant gas sensors. Gas sensors need to be packaged during the production process, and during the packaging process, most of them use a dispensing packaging method, that is, the sensor chip is attached to the surface of the substrate with packaging glue to complete the packaging.

[0003] Patent publication number CN220635029U discloses a gas sensor packaging device, including a mounting plate, two dispensing mechanisms and two cleaning mechanisms. The two dispensing mechanisms are symmetrically distributed on the left and right, and the two cleaning mechanisms are connected to the two dispensing mechanisms in a one-to-one correspondence. The dispensing mechanisms are connected to the mounting plate.

[0004] In the above technology, the cleaning block is driven to rotate by the connecting plate, so that the cleaning block brushes off the residual glue on the dispensing tube to remove the residual glue. However, the diameter of the dispensing tube is specific, so the flow rate of the glue cannot be adjusted. The types of sensors are diverse, and the sizes of the substrates are also different. For larger substrates, the flow rate of the glue is slower, which reduces the packaging speed. Therefore, innovation is made in this technology. Utility Model Content

[0022] See also Figure 1-4 , the utility model provides a technical solution for packaging equipment for gas sensors:

[0023] Example 1:

[0024] like Figure 1-3As shown, a packaging device for a gas sensor includes a packaging cylinder 1 and a packaging tube 2. The packaging tube 2 is arranged at the bottom of the packaging cylinder 1. One end of the packaging cylinder 1 is sleeved with a first gear 5. A vertical rod 6 is provided at the bottom of the first gear 5. One end of the vertical rod 6 is provided with a U-shaped plate 7. One end of the packaging tube 2 is provided with a first packaging disk 3. The bottom surface of the first packaging disk 3 is provided with a drip groove 4. The bottom of the first packaging disk 3 is provided with a second packaging disk 8. One end of the second packaging disk 8 is sleeved with a wrapping ring 9. The second packaging disk 8 is provided with a second packaging disk 8. A bonding groove 10 is provided on the bottom surface of the mounting tray 8, and a second gear 12 is provided on one side of the packaging cylinder 1. A bonding plate 15 is provided at the bottom of the second gear 12, and a plurality of scraping strips 16 are provided on the top of the bonding plate 15. The plurality of scraping strips 16 will intermittently scrape against the bottom surface of the second packaging tray 8 during the circular motion, so as to remove the glue attached to the surface of the bonding groove 10. The rotation of the second gear 12 drives the first gear 5 meshing with it to rotate, and then drives the second packaging tray 8 to rotate.

[0025] Example 2:

[0026] Based on the first embodiment, Figure 1 and Figure 4 As shown, one end of the extension rod 14 is fixedly connected to one end of the transmission rod 13, and the length of the extension rod 14 is less than the length of the transmission rod 13. One end of a plurality of scrapers 16 is fixedly connected to the top of the bonding plate 15, and the positions of the plurality of scrapers 16 are arranged at equal intervals. The utility model is a packaging device for a gas sensor, which is provided with a first packaging disk 3, a bonding groove 10, a transmission rod 13 and an extension rod 14. After the first gear 5 is engaged with the second gear 12, the wrapping ring 9 and the vertical rod 6 are fixed by the U-shaped plate 7, so that the wrapping ring 9 also rotates, and then drives the second packaging disk 8 fixed thereto to rotate, and the second gear 12 rotates.

[0027] Working principle: Gas sensor is an important sensor that can perform gas analysis and detection. The device can sense specific gases and determine their concentrations. The most common ones are: resistive gas sensors, capacitive gas sensors and resonant gas sensors. Gas sensors need to be packaged during the production process, and during the packaging period, most of them adopt the packaging form of dispensing, that is, the sensor chip is attached to the surface of the substrate through the packaging glue to complete the packaging. The packaging glue is injected into the interior of the packaging cylinder 1 in advance, and the sensor chips are placed at the bottom of the packaging cylinder 1 in turn. Through the downward flow of the glue, the glue will first be diverted to the interior of the first packaging disk 3 through the packaging tube 2, and then drip down along the bonding groove 10, and finally drip onto the substrate where the sensor chip is set. The substrate and the sensor chip are adhered by the glue. As the servo motor 11 starts, it will drive the second gear 12 to rotate synchronously, and several scrapers 16 are making circles. During the movement, it will intermittently scrape against the bottom surface of the second packaging disk 8, and thus the glue attached to the surface of the bonding groove 10 can be removed. The rotation of the second gear 12 drives the first gear 5 meshing with it to rotate, and then drives the second packaging disk 8 to rotate. During the rotation of the second packaging disk 8, the bonding area between the bonding groove 10 and the drip groove 4 gradually changes, so that the flow rate of the glue dripping can be adjusted, which improves the practicality of the packaging equipment and can adjust the packaging speed. After the first gear 5 is engaged with the second gear 12, since the wrapping ring 9 and the vertical rod 6 are fixed by the U-shaped plate 7, the wrapping ring 9 also rotates, and then drives the second packaging disk 8 fixed thereto to rotate. The rotation of the second gear 12, under the connection of the transmission rod 13 and the extension rod 14, also drives the bonding plate 15 to rotate, so that the contact time of several scraping strips 16 with the bottom surface of the bonding groove 10 can be adjusted.
