Technical Field

[0001] This utility model belongs to the field of infrared sensor technology, specifically an alignment device for assembling infrared sensor caps. Background Technology

[0002] Infrared sensors typically use a cap as a metal encapsulation component to encapsulate the internal pyroelectric detection element and also serve as electromagnetic shielding.1 The top of the cap usually has a light-transmitting hole, and an infrared filter is bonded and fixed inside the hole with epoxy resin. Its function is to allow infrared light within a specific wavelength range to pass through to the sensing chip inside the sensor and to prevent visible light from interfering with the pyroelectric detection element.1 Some enhanced products also incorporate a focusing lens between the infrared filter and the sensing chip to improve the sensing chip's sensitivity to infrared light.

[0003] Meanwhile, a multi-channel infrared sensor with the publication number CN222774115U is disclosed, including a tube base, a ceramic circuit board fixed on the top of the tube base, and a window cap encapsulated on the top of the tube base. The window cap has a detection window and a sapphire lens. A detection module is provided on one side of the ceramic circuit board. The detection module includes an upper support and a lower support that are stacked and fixed. Both the upper support and the lower support include a support frame. The support frame has a number of equidistant arrayed assembly slots. A main conduction column is provided in the assembly slot. A heat dissipation notch is provided on one side of the assembly slot. The top of the support frame has a mating slot, and the bottom of the support frame has a mating protrusion corresponding to the mating slot.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The following describes an embodiment of this utility model based on its overall structure.

[0029] like Figures 1 to 5 As shown, this utility model provides an alignment device for assembling infrared sensor caps, including a clamping device 12. The clamping device 12 includes a frustum 121, with a cylinder 122 rotatably mounted inside the frustum 121. A spring collet 14 is fitted inside the cylinder 122, and a tube bottom 15 is fitted inside the spring collet 14. Grooves 16 are formed at both ends of the tube bottom 15, and a magnetic groove 13 is formed at the lower end of the groove 16. Buckles 17 are fixedly mounted on both the front and rear sides of the upper end of the tube bottom 15. The upper end face of 5 is fitted with a tube cap 19. The tube cap 19 has through holes 20 on both the front and rear sides, and the through holes 20 are fitted with the buckle 17. The assembly accuracy can be improved by using the frustum 121 and the cylinder 122. The spring collet 14 has a certain elasticity and can generate a uniform clamping force on the tube bottom 15, which firmly fixes the tube bottom 15 in the cylinder 122. In this way, the tube bottom 15 will not easily shake or shift during the assembly process, thus ensuring the stability of the assembly process.

[0030] In this embodiment, a dust cover 21 is fixedly installed inside the cap 19. A second groove 18 is opened inside the lower end of the cap 19. A second spring 25 is fixedly installed inside the groove 18. A rectangular block 22 is fixedly installed on the lower end face of the second spring 25. A cuboid 23 is fixedly installed on the outer side of the rectangular block 22. A magnetic block 24 is fixedly installed on the upper end face of the cuboid 23. A second magnetic block 26 is fixedly installed on the lower end face of the cuboid 23. The second magnetic block 26 is fitted into the groove 27. The cap 19 and the bottom 15 can be fixed a second time through the rectangular block 22 and the cuboid 23. The rectangular block 22 can be fixed through the magnetic block 26 and the magnetic groove 13.

[0031] A base 1 is attached to the outside of the clamping device 12. A column 8 is fixedly installed on the right side of the upper end face of the base 1. A fixing groove 28 is opened in the middle of the column 8. A support plate 2 is fixedly installed on the rear side of the upper end face of the base 1. The pipe cap 19 held by the gripper 6 can be positioned by the column 8.

[0032] The support plate 2 has a groove 3 27 inside, and a rotating shaft 5 is rotatably installed inside the groove 3 27. A connecting plate 3 is fixedly installed on the front end face of the rotating shaft 5, and a motor 4 is fixedly installed on the front end face of the upper end face of the connecting plate 3. The rotating shaft 5 facilitates the movement of the gripper 6, making it easier to clamp and move the tube cap 19.

[0033] A gripper 6 is fixedly provided on the lower end face of the motor 4, and the gripper 6 and the connecting plate 3 are rotated to the set position. An anti-slip pad 7 is fixedly provided on the inner side of the gripper 6, and a connecting block 9 is fixedly provided on the right end face of the gripper 6. The gripper 6 can be rotated by the motor 4, so that the connecting block 9 on the outer side of the gripper 6 enters the fixing groove 28 opened in the column 8, so that it can be positioned.

[0034] A spring 11 is fixedly installed inside the connecting block 9, and an inclined plate 10 is fixedly installed on the right end face of the spring 11. The inclined plate 10 can fix the connecting block 9 inside the column 8, preventing the gripper 6 from shaking randomly.

[0035] Working principle and process of the alignment device for assembling infrared sensor caps:

[0036] The worker places the pipe bottom 15 into the spring collet 14, then places it into the cylinder 122 inside the clamping device 12. The cylinder 122 is tightened using the frustum 121, causing it to apply pressure to the spring collet 14, thus fixing the pipe bottom 15. The clamping device 12 is then placed inside the base 1. The pipe cap 19 is lifted by the jaws 6 at the lower end of the connecting plate 3, connected to the rotating shaft 5 inside the groove 27 of the support plate 2. The pipe cap 19 is moved to the designated position. The motor 4 is started, rotating the jaws 6 and causing the connecting block 9 on the outside of the jaws 6 to rotate. The connecting block 9 rotates into the fixing groove 28 on the upper right side of the column 8 of the base 1. The inclined plate 10 inside the connecting block 9 is held in place by the spring 11. When it pops out, the inclined plate 10 enters the interior of the fixing groove 28, which can move the tube cap 19 downward. When the buckle 17 on the tube bottom 15 enters the interior of the through holes 20 on the front and rear sides of the tube cap 19, the worker moves the rectangular block 22 inside the groove 28 at the lower end of the tube cap 19 downward, so that the magnetic block 26 on the lower side of the rectangular block 23 on the outer side of the rectangular block 22 fits tightly with the groove 3 27 inside the groove 16 on the front and rear sides of the tube bottom 15. The worker then uses a stick to retract the inclined plate 10 inside the column 8, so that the gripper 6 moves. The worker then removes the clamping device 12, moves it out of the interior of the base 1, and takes it out. This serves as an alignment device for assembling the infrared sensor tube cap.
