Description

Technical Field

[0001] The present invention relates to the technical field of infrared detector packaging, and specifically to an infrared detector packaging structure and a packaging method. Background Technique

[0002] Infrared detectors are mainly used in infrared thermal imaging technology. The packaged infrared detector detects the infrared thermal radiation of an object, senses the temperature distribution of the object, and converts it into a weak electrical signal. The subsequent circuit amplifies and logically processes the electrical signal to collect the temperature distribution of the target object. The image processing software processes the amplified output electrical signal as described above to present a visible light image of the object's temperature distribution.

[0003] Referring to the Chinese patent with the application number: "201920753245.X", "A Miniature Infrared Detector Packaging Device", this patent places several groups of fixing plates on the base, then fixes the inner main board of the miniature infrared detector on the fixing plates, and starts the suction device to adsorb the outer shell of the miniature infrared detector inside the packaging groove. Then, it starts the elevator to drive the outer shell of the miniature infrared detector to move downward to package the inner main board of the miniature infrared detector, so as to package multiple groups of miniature infrared detectors at one time, solving the problem of the small single - packaging quantity of the packaging shell.

[0004] However, when packaging the packaging shell, this device directly places the fixing plate on the base. When the outer shell of the miniature infrared detector is pressed down for packaging, the fixing plate is prone to dislocation, resulting in the failure of the overall packaging of the miniature infrared detector. For this, we propose an infrared detector packaging structure and a packaging method to solve the above problems. Summary of the Invention

[0016] A packaging method for an infrared detector packaging structure includes the following steps:

[0017] Step 1: Place the infrared fixing plate and the outer shell. When placing, place the fixing plate between the two placement seats, then the reset spring is stressed for simple clamping, and then the vacuum generator located above works, generating vacuum suction through the suction pipe, place the outer shell below the vacuum suction head, and the vacuum suction head generates suction through the vacuum generator to fix the outer shell.

[0018] Step 2: Encapsulate the infrared detector. During encapsulation, the forward and reverse motors located above operate and rotate, driving the bevel gear 2 on one side to rotate. The rotation of bevel gear 2 drives the bevel gear 1 to rotate, thereby driving the threaded rod below to rotate, and then driving the connecting platform on the outside to move downward, causing the top plate to drive the lower housing to gradually move downward. When bevel gear 2 rotates, the runner 2 on one side will rotate synchronously and drive the lower runner 4 to rotate through belt 2. When runner 4 rotates, it will drive the gear 1 on one side to rotate through guide rod 1. The rotation of gear 1 will drive the tooth rail on one side to move upward. When the tooth rail moves upward, it will drive gear 2 to rotate. The rotation of gear 2 drives the lower gear 3 to rotate, thereby driving the lower guide rod 2 and the runner 2 on one side to rotate, and driving the two runners 1 below to rotate through belt 1. Therefore, it can drive the connecting rod on one side to rotate, and drive the two mounting platforms on the outside to move in opposite directions through the left and right hand threads, jointly clamping the fixing plate located in the middle position;

[0019] Step 3: When clamping the fixing plate, the housing located above gradually moves downward. When the housing is about to approach the fixing plate, and after the fixing plate is fastened, the tooth rail on one side disengages from gear 1, and gear 2 thus stops rotating, causing the entire fastening mechanism to stop working. Then, the forward and reverse motor located above continues to operate, driving the lower housing to closely adhere to the fixing plate with glue. When the tooth rail moves upward, it will continuously mesh with gear 1;

[0020] Step 4: After the infrared detector is encapsulated, the air compressor located below operates and pumps the high-temperature gas generated by the heater through the air pump. The high-temperature gas is transported through the gas pipeline 1 and gas pipeline 2 and blown out through the air nozzle to quickly solidify the glue between the fixing plate and the housing.

[0021] The present invention provides an infrared detector encapsulation structure. Compared with the prior art, it has the following beneficial effects:

[0022] (1) For this infrared detector packaging structure and packaging method, when the forward and reverse motor operates and rotates, it drives the bevel gear two on one side to rotate. The rotation of the bevel gear two drives the bevel gear one to rotate, thereby driving the lower threaded rod to rotate, and then driving the outer connecting platform to move downward, causing the top plate to drive the lower housing to gradually move downward. When the bevel gear two rotates, the runner two on one side will rotate synchronously and drive the lower runner four to rotate through the belt two. When the runner four rotates, it drives the gear one on one side to rotate through the guide rod one. The rotation of the gear one drives the tooth rail on one side to move upward. When the tooth rail moves upward, it drives the gear two to rotate. The rotation of the gear two drives the lower gear three to rotate, thereby driving the lower guide rod two and the runner two on one side to rotate, and driving the two lower runners one to rotate through the belt one, so as to clamp the fixed plate. After the fixed plate is fastened, the housing approaches the fixed plate, and the tooth rail on one side disengages from the gear one, and the gear two thus stops rotating, causing the entire fastening mechanism to stop working. Then, the forward and reverse motor above continues to operate, driving the lower housing to closely adhere to the fixed plate through glue. Therefore, when fixing, the housing will come into contact with the lower fixed plate, making the housing and the fixed plate maintain the same center and avoiding the dislocation of the fixed plate during pressing.

[0023] (2) For this infrared detector packaging structure and packaging method, through the setting of the fastening mechanism, when the connecting rod rotates, it drives the forward and reverse threads to rotate, thereby driving the mounting table to move. When the mounting table moves, it drives the two placement seats to move relatively, jointly pressing the fixed plate, thus avoiding the situation where the fixed plate is directly placed, resulting in unstable placement of the fixed plate and causing the overall packaging of the infrared detector to fail.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 - 10 , the present invention provides two technical solutions, specifically including the following embodiments:

[0037] Embodiment 1:

[0038] An infrared detector packaging structure includes a base 1. At both ends below the base 1, fixing blocks 10 are fixedly installed. Below the fixing blocks 10, anti-slip pads 11 are fixedly installed for placing the whole device. Above the fixing plate 43 on one side of the base 1, there is a pressing component. The pressing component includes a placement frame 3. The placement frame 3 is fixedly installed at one end of the base 1. In the middle of the inner side of the placement frame 3, a threaded rod 35 is rotatably arranged. At the top of the threaded rod 35, a first bevel gear 15 is fixedly installed. On one side of the first bevel gear 15, there is also a second bevel gear 16. The first bevel gear 15 and the second bevel gear 16 are meshed with each other. On one side of the second bevel gear 16, a connecting column 17 is fixedly installed. At the top of one side of the placement frame 3, a fixed platform 19 is fixedly installed. The connecting column 17 is rotatably arranged inside the fixed platform 19. On one side of the connecting column 17, a positive and negative motor 18 is fixedly installed, which is used to drive the threaded rod 35 on one side to rotate, so as to drive the top plate 9 to move up and down. The positive and negative motor 18 is fixedly installed on one side of the fixed platform 19. On one side of the connecting column 17, a second runner 22 is fixedly installed. Below the connecting column 17 on one side of the placement seat 51, a first guide rod 23 is rotatably arranged. On the first guide rod 23, a fourth runner 31 is fixedly installed. The second runner 22 and the fourth runner 31 are sleeved with a second belt 21 outside. On the first guide rod 23, on one side of the fourth runner 31, a first gear 24 is fixedly installed. Below the first guide rod 23 on one side of the placement frame 3, a third guide rod 30 is rotatably arranged. Outside the third guide rod 30, a second gear 25 is fixedly installed. The second gear 25 is arranged below the first gear 24. The second gear 25 and the first gear 24 have the same diameter and are used to mesh with a tooth rail 33 respectively. When the tooth rail 33 moves, it will drive the second gear 25 to rotate. On one side of the first gear 24 and the second gear 25, there is a tooth rail 33. The tooth rail 33 meshes with the first gear 24 and the second gear 25 respectively. On one side of the placement frame 3, a limit seat 32 is fixedly installed. The tooth rail 33 is slidably arranged inside the limit seat 32. Below the third guide rod 30 on one side of the placement frame 3, a second guide rod 29 is rotatably arranged. Outside the second guide rod 29, a third gear 28 is fixedly installed. The third gear 28 and the second gear 25 are meshed with each other. The diameter of the third gear 28 is smaller than that of the second gear 25. On the second guide rod 29, on one side of the third gear 28, a third runner 26 is fixedly installed. The third runner 26 and two first runners 5 are sleeved with a first belt 4 outside. Outside the threaded rod 35, there is a connecting platform 34. On both sides of the inner part of the placement frame 3, limit strips 36 are fixedly installed. Grooves are opened on both sides of the connecting platform 34. The limit strips 36 are arranged inside the grooves to improve the moving effect of the connecting platform 34. On one side of the connecting platform 34, a top plate 9 is fixedly installed. On the top plate 9, there is a vacuum adsorption component. A fastening mechanism is also arranged on the base 1;The fastening mechanism includes two connecting rods 2. On both sides of the base 1, clamping grooves 45 are formed. The two connecting rods 2 are respectively rotatably arranged inside the two clamping grooves 45. On both ends of the two connecting rods 2, left - hand and right - hand threads 40 are formed. On the outer sides of the left - hand and right - hand threads 40 on the connecting rods 2, mounting platforms 44 are arranged. On both sides of the clamping grooves 45 on the base 1, limiting grooves 47 are formed. Inside the two limiting grooves 47, guide rods 46 are respectively fixedly installed. On both sides of the mounting platforms 44, sliders 42 are respectively fixedly installed. The two sliders 42 are respectively slidably arranged inside the limiting grooves 47. A guide hole is formed in the middle of the slider 42, and the guide rod 46 is inserted inside the guide hole to improve the stability of the mounting platform 44 during movement. There are two mounting platforms 44 in each group, which are arranged oppositely. On each group of mounting platforms 44, mounting seats 41 are fixedly installed. On both sides of the mounting seats 41, insertion holes 49 are formed. Inside the two insertion holes 49, insertion rods 50 are respectively slidably arranged. One end of the two insertion rods 50 is fixedly installed with a placement seat 51. On the outer sides of the two insertion rods 50, return springs 48 are arranged. In the initial state, the return springs 48 extend to tightly press the placement seat 51, thereby simply fixing the fixing plate 43. When the two mounting platforms 44 move in opposite directions, the return springs 48 will be compressed, causing the return springs 48 to contract. Then the insertion rods 50 move outwards, enabling the two placement seats 51 to fasten the fixing plate 43. Both ends of the return springs 48 are respectively fixedly installed on one side of the mounting seat 41 and the placement seat 51. The two placement seats 51 are arranged oppositely, and a fixing plate 43 is arranged between the two placement seats 51. One end of each of the two connecting rods 2 is fixedly installed with a first runner 5. Specifically, for the encapsulation of the infrared detector, during encapsulation, the positive - negative motor 18 located above operates and rotates, driving the second bevel gear 16 on one side to rotate. The rotation of the second bevel gear 16 drives the first bevel gear 15 to rotate, thereby driving the lower threaded rod 35 to rotate, and then driving the outer connecting platform 34 to move downward, causing the top plate 9 to drive the lower housing to gradually move downward. When the second bevel gear 16 rotates, the second runner 22 on one side will rotate synchronously and drive the lower fourth runner 31 to rotate through the second belt 21. When the fourth runner 31 rotates, it will drive the first gear 24 on one side to rotate through the first guide rod 23. The rotation of the first gear 24 will drive the first tooth rail 33 to move upward. When the first tooth rail 33 moves upward, it will drive the second gear 25 to rotate. The rotation of the second gear 25 drives the lower third gear 28 to rotate, thereby driving the lower second guide rod 29 and the second runner 22 on one side to rotate. Through the first belt 4, the two lower first runners 5 are driven to rotate. Therefore, it can drive one side connecting rod 2 to rotate, and drive the two outer mounting platforms 44 to move in opposite directions through the left - hand and right - hand threads 40, jointly clamping the fixing plate 43 located in the middle position;When clamping the fixing plate 43, the upper housing gradually moves downward. When the housing is about to approach the fixing plate 43 and after the fixing plate 43 is fastened, the tooth rail 33 on one side disengages from the first gear 24, and the second gear 25 stops rotating accordingly, causing the entire fastening mechanism to stop working. Then, the forward and reverse motor 18 above continues to operate, driving the lower housing to adhere tightly to the fixing plate 43 with glue. When the tooth rail 33 moves upward, it will continuously mesh with the first gear 24.;

[0039] Furthermore, limit rods 6 are fixedly installed at the four corners of the base 1, and fixing rings 7 are fixedly installed at the four corners of the top plate 9. The fixing rings 7 are slidably arranged outside the limit rods 6, enabling the top plate 9 to be limited when moving downward and improving the stability of the top plate 9 during downward movement.

[0040] Furthermore, the vacuum suction attachment includes a vacuum generator 14, which is fixedly installed on one side of the top plate 9. A first connecting pipe 13 is fixedly installed on one side of the vacuum generator 14. One end of the first connecting pipe 13 is fixedly installed with a second connecting pipe 20. Both ends of the second connecting pipe 20 are fixedly installed with air extraction pipes 8. Both ends of the two air extraction pipes 8 are fixedly installed with vacuum suction heads 12. The vacuum suction heads 12 are arranged below the top plate 9, and the vacuum suction heads 12 and the fixing plate 43 are on the same central line. Specifically, place the housing inside the vacuum suction heads 12, and then the vacuum generator 14 above operates to generate vacuum suction through the suction pipes. Place the housing below the vacuum suction heads 12, and the vacuum suction heads 12 generate suction through the vacuum generator 14 to fix the housing.

[0041] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0042] During operation, first place the infrared fixing plate 43 and the housing. When placing, place the fixing plate 43 between the two placement seats 51, and then the return spring 48 is stressed for simple clamping. Then, the vacuum generator 14 above operates to generate vacuum suction through the suction pipes. Place the housing below the vacuum suction heads 12, and the vacuum suction heads 12 generate suction through the vacuum generator 14 to fix the housing;

[0043] Encapsulate the infrared detector. During encapsulation, the forward and reverse motor 18 located above operates and rotates, driving the bevel gear two 16 on one side to rotate. The rotation of the bevel gear two 16 drives the bevel gear one 15 to rotate, thereby driving the threaded rod 35 below to rotate, and then driving the outer connecting platform 34 to move downward, causing the top plate 9 to drive the lower housing to gradually move downward. When the bevel gear two 25 rotates, the runner two 22 on one side will rotate synchronously and drive the lower runner four 31 to rotate through the belt two 21. When the runner four 31 rotates, it will drive the gear one 24 on one side to rotate through the guide rod one 23. The rotation of the gear one 24 will drive the tooth rail 33 on one side to move upward. When the tooth rail 33 moves upward, it will drive the gear two 25 to rotate. The rotation of the gear two 25 drives the lower gear three 28 to rotate, thereby driving the lower guide rod two 29 and the runner two 22 on one side to rotate, and driving the two runners one 5 below to rotate through the belt one 4. Therefore, it can drive the connecting rod 2 on one side to rotate and drive the two mounting platforms 44 on the outside to move in opposite directions through the left - hand and right - hand threads 40, jointly clamping the fixing plate 43 located in the middle position; when clamping the fixing plate 43, the upper housing gradually moves downward. When the housing is about to approach the fixing plate 43 and after the fixing plate 43 is fastened, the tooth rail 33 on one side disengages from the gear one 24, and the gear two 25 thus stops rotating, causing the entire fastening mechanism to stop working. Then, the forward and reverse motor 18 located above continues to operate, driving the lower housing to adhere tightly to the fixing plate 43 with glue, and the tooth rail 33 will continuously mesh with the gear one 24 when moving upward.

One end of each of the two groups of air blowing pipes 37 is fixedly installed with a support plate 39. One side of the support plate 39 is fixedly installed with an air blowing nozzle 52. The air blowing nozzle 52 is communicated with the air blowing pipe 37. Two support rods 38 are fixedly installed on both sides below the support plate 39. The lower part of the support rod 38 is fixedly installed on one side of the placement seat 51. The air blowing nozzles 52 are arranged on both sides of the fixing plate 43. Specifically, after the infrared detector is encapsulated, the air compressor 53 located below operates and extracts and conveys the high - temperature gas generated by the heater 55 through the air pump. Through the conveyance of the air delivery pipe one 54 and the air delivery pipe two 56, the high - temperature gas will be blown out through the air blowing nozzles 52 to quickly solidify the glue between the fixing plate 43 and the housing.

[0046] Embodiment Three:

[0047] An infrared detector packaging method, comprising the following steps:

[0048] Step 1: Place the infrared ray fixing plate 43 and the outer shell. When placing, place the fixing plate 43 between two placing seats 51. Then, the reset spring 48 is stressed for simple clamping. Then, the vacuum generator 14 located above works, generates a vacuum suction force through the suction pipe, places the outer shell below the vacuum suction head 12, and the vacuum suction head 12 generates a suction force through the vacuum generator 14 to fix the outer shell;

[0049] Step 2: Package the infrared detector. When packaging, the forward and reverse motor 18 located above works and rotates, driving the bevel gear two 16 on one side to rotate. The rotation of the bevel gear two 16 drives the bevel gear one 15 to rotate, thereby driving the lower threaded rod 35 to rotate, and then driving the outer connecting platform 34 to move downward, so that the top plate 9 drives the lower outer shell to gradually move downward. When the bevel gear two 16 rotates, the runner two 22 on one side will rotate synchronously and drive the lower runner four 31 to rotate through the belt two 21. When the runner four 31 rotates, it will drive the gear one 24 on one side to rotate through the guide rod one 23. The rotation of the gear one 24 will drive the tooth rail 33 on one side to move upward. When the tooth rail 33 moves upward, it will drive the gear two 25 to rotate. The rotation of the gear two 25 drives the lower gear three 28 to rotate, thereby driving the lower guide rod two 29 and the runner two 22 on one side to rotate, and driving the two runners one 5 below through the belt one 4. Therefore, it can drive the connecting rod 2 on one side to rotate, and drive the two mounting platforms 44 on the outside to move in opposite directions through the left and right hand threads 40, and jointly clamp the fixing plate 43 located in the middle position;

[0050] Step 3: When clamping the fixing plate 43, the upper outer shell gradually moves downward. When the outer shell is about to approach the fixing plate 43 and the fixing plate 43 is fastened, the tooth rail 33 on one side disengages from the gear one 24, and the gear two 25 stops rotating accordingly, so that the entire fastening mechanism stops working. Then, the forward and reverse motor 18 located above continues to work, driving the lower outer shell to closely adhere to the fixing plate 43 through glue. When the tooth rail 33 moves upward, it will continuously mesh with the gear one 24;

[0051] Step 4: After the infrared ray detector is packaged, the air compressor 53 located below works, and extracts and conveys the high-temperature gas generated by the heat generator 55 through the air pump. The high-temperature gas is conveyed through the air delivery pipe one 54 and the air delivery pipe two 56, and will be blown out through the air blowing nozzle 52 to quickly solidify the glue between the fixing plate 43 and the outer shell.

[0052] The above has described in detail an embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the present invention.

10. A packaging method using the infrared detector packaging structure according to any one of claims 1-9, characterized in that, It includes the following steps: Step 1: Place the infrared fixing plate (43) and the outer shell. When placing, place the fixing plate (43) between two placement seats (51). Then the return spring (48) is stressed and simply clamped. Then the vacuum generator (14) located above works, generating vacuum suction through the suction pipe, and place the outer shell below the vacuum suction head (12). The vacuum suction head (12) generates suction through the vacuum generator (14) to fix the outer shell. Step 2: Package the infrared detector. When packaging, the forward and reverse motor (18) located above works and rotates, driving the bevel gear two (16) on one side to rotate. The rotation of the bevel gear two (16) drives the bevel gear one (15) to rotate, thereby driving the lower threaded rod (35) to rotate, and then driving the outer connecting platform (34) to move downward, so that the top plate (9) drives the lower outer shell to gradually move downward. When the bevel gear two (16) rotates, the runner two (22) on one side will rotate synchronously and drive the lower runner four (31) to rotate through the second belt (21). When the runner four (31) rotates, it will drive the gear one (24) on one side to rotate through the first guide rod (23). The rotation of the gear one (24) will drive the tooth rail (33) on one side to move upward. When the tooth rail (33) moves upward, it will drive the gear two (25) to rotate. The rotation of the gear two (25) drives the lower gear three (28) to rotate, thereby driving the lower second guide rod (29) and the runner two (22) on one side to rotate, and driving the two lower runners one (5) to rotate through the first belt (4). Therefore, it can drive the connecting rod (2) on one side to rotate, and drive the two outer mounting platforms (44) to move in opposite directions through the left - and - right - hand threads (40) to jointly clamp the fixing plate (43) located in the middle position. Step 3: When clamping the fixed plate (43), the upper housing gradually moves downward. When the housing is about to approach the fixed plate (43), after the fixed plate (43) is fastened, the tooth rail (33) on one side disengages from the first gear (24), and the second gear (25) stops rotating accordingly, causing the entire fastening mechanism to stop working. Then, the forward and reverse motor (18) above continues to operate, driving the lower housing to adhere tightly to the fixed plate (43) with glue. When the tooth rail (33) moves upward, it will continuously mesh with the first gear (24); Step 4: After the infrared detector is encapsulated, the air compressor (53) below operates and pumps the high-temperature gas generated by the heat generator (55) through the air pump. The high-temperature gas is conveyed through the first gas pipeline (54) and the second gas pipeline (56) and blown out through the air blowing nozzle (52) to quickly solidify the glue between the fixed plate (43) and the housing.
