Description

Technical Field

[0001] The present invention relates to the technical field of gas sensor packaging devices, and particularly to a gas sensor packaging device modified with nanomaterials. Background Art

[0002] A gas sensor is a sensor used to detect whether a specific gas exists within a certain area range and to continuously measure the concentration of gas components. Based on the principle of electrochemical reaction, it measures the gas concentration through the oxidation-reduction process between the material and the target gas. The sensing material in an electrochemical sensor is usually a metal catalyst with relatively high electrical conductivity, such as platinum or tungsten. When the target gas contacts the sensing material, an oxidation-reduction reaction occurs, resulting in a change in current, thereby measuring the gas concentration. The main application fields include industrial production, indoor air quality detection, environmental monitoring, medical health, other fields, etc. Generally speaking, as an important detection device, gas sensors play an irreplaceable role in modern society.

[0003] Existing gas sensors are generally modified with nanomaterials. After modification, the gas sensors have characteristics such as high sensitivity and good selectivity. However, when applying the nanomaterials, there are often problems of uneven application, resulting in the gas sensor being unable to be used normally after welding. At the same time, during the welding process, arc welding is generally used. During welding, the welding points are often unevenly heated or the temperature is too high, causing the gas sensor to undergo thermal stress deformation during welding, resulting in the gas sensor being unable to be used normally. Then, before welding, there are some impurities on the surface of the gas sensor, which will affect the welding process. Therefore, we have proposed a gas sensor packaging device modified with nanomaterials. Summary of the Invention

An arc-shaped through groove 14 is arranged between the support plate 8 and the panel 1, and its size is equal to that of the first synchronous belt 17. Its main function is to supply the transmission component 4 to reciprocally convey the gas sensors to be encapsulated. In a preferred embodiment of this embodiment, the transmission component 4 includes a support plate 8 fixed to the bottom of the first box body 3. A second arc-shaped sliding groove 13 is provided at the top of the support plate 8, and a first arc-shaped sliding groove 12 is provided at the top of the panel 1. A plurality of groups of first U-shaped rods 9 are slidably connected to the inner walls of the second arc-shaped sliding groove 13 and the first arc-shaped sliding groove 12 at equal distances.

Two groups of convex through holes are symmetrically provided on the left and right sides of the first box body 3; Further, in the above solution, after the four support columns 2 are arranged, ensure that the panel 1 is in a horizontal state at this time, and then place the gas sensors to be encapsulated in the placement table 10 in sequence. It should be noted here that the size of the placement table 10 matches the sensor, and the gas sensors to be encapsulated will not fall off after being placed in the placement table 10. Then, start the motor 18 at the bottom of the support plate 8 to drive the second synchronous wheel 16 to rotate. The second synchronous wheel 16 will drive the first synchronous wheel 15 to rotate through the first synchronous belt 17. A number of groups of support rods 11 are equidistantly arranged on the top of the first synchronous belt 17. The main function of the support rods 11 is to support the placement table 10, and the support rods 11 penetrate through the first U-shaped rod 9.

A driving component for realizing the rotation of the cleaning roller 40 is installed on the right side of the second box body 20; When the placement table 10 drives the gas sensor to be encapsulated into the second box body 20, the driving assembly will drive two first push rods 27 to move forward at this time. While the two first push rods 27 are moving forward, they will force the two first gears 38 to engage with and rotate the two first racks 26. It should be mentioned here that a cleaning roller 40 is provided at the bottom of the first slide plate 25, and the cleaning roller 40 is coaxially fixed with the two first gears 38. Therefore, while the first gears 38 are rotating, the cleaning roller 40 will also rotate and move forward while rotating.

It should be noted here that a number of flexible cleaning brushes are provided on the surface of the cleaning roller 40, and when it is cleaning, it will not cause scratches on the surface of the gas sensor and make the gas sensor fall off from the inside of the placement table 10.

A driving assembly for realizing the reciprocating rolling of the feeding roller 44 is installed on the right side of the third box body 21; Next, when the gas sensor is driven into the third box body 21 by the placement table 10, at this time, driven by the driving assembly, the two second gears 42 will engage with and rotate the second racks 33. At the same time, a feeding roller 44 is rotatably connected to the bottom of the second slide plate 60, and a discharge port and a connecting pipe are provided on its surface and inside.

Then, driven by the placement table 10, it will be conveyed to the welding assembly 5. In the above, the two driving assemblies mentioned are regarded as the same driving assembly; Specifically, the driving assembly includes a first threaded rod 29 rotatably connected to the right outer wall of the second box body 20.

The fourth synchronous pulley 51 is coaxially and fixedly connected with the first threaded rod 29, and the third synchronous pulley 49 is coaxially and fixedly connected with the second threaded rod 32. The third synchronous pulley 49 and the fourth synchronous pulley 51 are connected by a second synchronous belt 50. On the right side of the fourth synchronous pulley 51, a reciprocating motor 52 is fixed. The output end of the reciprocating motor 52 is fixedly connected with the fourth synchronous pulley 51; When the placement table 10 drives the gas sensor into the interior of the second box body 20, the driving assembly starts the reciprocating motor 52. The reciprocating motor 52 drives the fourth synchronous pulley 51 to rotate, and drives the third synchronous pulley 49 to rotate through the second synchronous belt 50.

The welding component 5 is mainly used for welding and encapsulating the gas sensor. The welding component 5 includes a first fixing plate 55 fixed to the right side of the inner wall of the first box body 3. A cylinder 54 is installed on the top of the first fixing plate 55. Four slide bars 53 are symmetrically fixed to the bottom of the first fixing plate 55. The outer walls of the four slide bars 53 are slidably connected to the same second fixing plate 57.

The output end of the cylinder 54 is fixedly connected to the second fixing plate 57. Among them, the four corners of the second fixing plate 57 are respectively slidably connected to the outer walls of the four slide bars 53. Therefore, the second fixing plate 57 can only move up and down. This design can achieve that when the welding cover 56 welds the placement table 10, there is no deviation. A welding device 59 is provided inside the welding cover 56. Note that the welding device 59 is an existing welding device. The welding process will not be elaborated here in detail because this welding technology is an existing technology. A third spring 58 is provided on the top of the welding device 59. Its main function is to enable the welding device 59 to fully fit the placement table 10. At the same time, the size of the welding cover 56 is adapted to the placement table 10. Therefore, it can be achieved that when the welding device 59 welds, it will not generate thermal stress deformation due to overheating, thereby affecting the normal use of the gas sensor. Finally, after the cylinder 54 is started, the motor 18 will stop when the welding device 59 is welding to ensure that there is no deviation during the welding process.

It should be noted here that the size of the placement table 10 matches the sensor, and the gas sensors to be encapsulated will not fall or have other problems after being placed in the placement table 10. Then, start the motor 18 at the bottom of the support plate 8 to drive the second synchronous wheel 16 to rotate. The second synchronous wheel 16 will drive the first synchronous wheel 15 to rotate through the first synchronous belt 17. A number of support rods 11 are equidistantly arranged on the top of the first synchronous belt 17. The main function of the support rods 11 is to support the placement table 10, and the support rods 11 penetrate through the first U-shaped rod 9. It should be noted here that first arc-shaped chutes 12 and second arc-shaped chutes 13 are opened on the top of both the panel 1 and the support plate 8. The distance between these two is equal to the size of the first U-shaped rod 9, and the two ends of the first U-shaped rod 9 are respectively slidably arranged inside the first arc-shaped chute 12 and the second arc-shaped chute 13. It should be mentioned here that the moving direction of the first U-shaped rod 9 is counterclockwise rotation, that is, it sequentially enters the inside of the first box body 3 from the left side of the first box body 3 and exits from the right side of the first box body 3. Then, when the gas sensor is driven by the placement table 10 into the third box body 21, at this time, driven by the driving component, the two second gears 42 will mesh with the second rack 33 and rotate. At the same time, a feeding roller 44 is rotatably connected to the bottom of the second sliding plate 60. There are a discharge port and a connecting pipe on its surface and inside. The connecting pipe is connected to the nano-material storage tank 19 at the top of the third box body 21, and the length of the connecting pipe will change with the moving distance of the feeding roller 44. When the feeding roller 44 moves, a layer of nano-material will be evenly coated on the surface of the gas sensor. Then, driven by the placement table 10, it will be transmitted to the welding component 5. In the above, the two driving components mentioned are regarded as the same driving component. When the placement table 10 passes through the second box body 20 and the third box body 21 respectively and comes to the welding component 5, at this time, start the air cylinder 54. The output end of the air cylinder 54 is fixed to the second fixing plate 57. Among them, the four corners of the second fixing plate 57 are respectively slidably connected to the outer walls of the four sliding rods 53. Therefore, the second fixing plate 57 can only move up and down. This design can ensure that the welding cover 56 does not shift when welding the placement table 10. There is a welding device 59 inside the welding cover 56. Note that the welding device 59 is an existing welding device. The welding process will not be described in detail here because this welding technology is an existing technology. There is a third spring 58 on the top of the welding device 59. Its main function is to enable the welding device 59 to fully fit the placement table 10. At the same time, the size of the welding cover 56 matches the placement table 10. Therefore, it can be ensured that when the welding device 59 welds, it will not generate thermal stress deformation due to overheating, thus affecting the normal use of the gas sensor. Finally,After the start of the cylinder 54, the motor 18 stops when the welding equipment 59 is welding to ensure that there is no deviation or the like during the welding process.
