Description

Technical Field

[0001] The present invention relates to infrared detector technology, and in particular to a packaging jig for an infrared detector module. Background Art

[0002] Infrared detectors are widely used in numerous fields, and their applications are expected to expand in the future, such as automotive night vision, healthcare, energy, and security. Vacuum packaging of infrared detectors is a complex process. With advancements in materials science and technology and the continuous expansion of application scenarios, the future of vacuum packaging for infrared detectors is expected to move towards smaller sizes and higher levels of integration. However, as packaged devices shrink in size, the current packaging method of wire-bonded chip interconnects will slow production speeds and reduce the yield of finished products, creating a need for miniaturization of infrared detector packaging devices.

[0003] The Chinese invention patent with publication number CN112701064A discloses a packaging jig and packaging method for an infrared detector module. The packaging jig and packaging method for the infrared detector module, in the process of using the packaging jig to package the infrared detector module, greatly improves the packaging efficiency of the infrared detector module because the multiple mounting portions of the carrier can respectively mount and fix a ceramic tube shell. Moreover, compared with the fixed transfer method using tweezers, when the present application uses a carrier to fix and transfer multiple ceramic tube shells, the contact area between each ceramic tube shell and the corresponding mounting portion is much larger than the contact area when clamped with tweezers, thereby improving the fixation reliability of each ceramic tube shell, avoiding the problem of poor packaging of the infrared detector module caused by jitter, and thereby improving the qualified rate of the infrared detector module after packaging.

[0004] When using existing equipment, if the positioning device of the jig is not precise enough, the detector module may shift or become unstable during the packaging process, affecting the packaging quality and consistency. At the same time, if the force used by the jig to fix the detector module is too strong or too weak, it will also cause problems. Excessive fixing force may cause damage or deformation of the detector component, while too little force may cause the module to move or become unstable during the packaging process. Moreover, if the jig cannot accommodate detector modules of different sizes, shapes, or versions, frequent jig replacement or adjustment may be required, affecting production efficiency and production line flexibility. As a result, a packaging jig for infrared detector modules has been developed. Summary of the Invention

[0034] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example: See Figures 1-9 A packaging fixture for an infrared detector module includes an operating platform 1, a support plate 11 is provided at the upper end of the operating platform 1, and a limiting component 2 is provided at the upper end of the support plate 11, and the infrared detector module is limited by the limiting component 2.

[0037] In this solution, the lower end of the support plate 11 is provided with a device with telescopic function such as an electric telescopic rod, which is connected to an external control device, thereby driving the support plate 11 to move up and down, so that the support plate 11 is always in the best position.

[0038] At the same time, a guide groove is provided at the upper end of the support plate 11, and the lower end of the limit component 2 is slidably connected to the inner wall of the guide groove. By adjusting the position of the limit component 2 on the guide groove, it can be suitable for most scenarios, and the lower end of the limit component 2 can be rotated on the inner wall of the guide groove, thereby enabling it to limit irregular parts.

[0039] Furthermore, the limiting assembly 2 includes two fixed blocks 21 connected to the support plate 11, and limiting plates 22 are provided on both sides of the upper ends of the two fixed blocks 21. A positioning rod 23 is provided between the two limiting plates 22, and circular plates 24 are slidably installed at both ends of the outer surface of the positioning rod 23, and the infrared detector module is fixed by the two circular plates 24.

[0040] In this embodiment, a hole is opened on one side of the limiting plate 22, and the inner wall of the hole is slidably connected to the outer surface of the positioning rod 23. At the same time, the positioning rod 23 is limited by the two limiting plates 22 to ensure that the positioning rod 23 is in a stable state as a whole. The outer surface of the circular plate 24 is provided with multiple groups of rubbers with different patterns, so that the circular plate 24 will not slide when fixing the infrared detector module, thereby ensuring the precise positioning of the infrared detector module during processing.

[0041] Furthermore, a first movable block 25 is arranged between the two circular plates 24, and a second movable block 251 is symmetrically arranged between the two first movable blocks 25. Multiple groups of first movable rods 26 are rotatably installed on the outer surface of the first movable block 25, and the multiple groups of first movable rods 26 are evenly distributed on the outer surface of the first movable block 25. The outer surface of the second movable block 251 is rotatably installed with a second movable rod 27 corresponding to the first movable rod 26, and the end of the first movable rod 26 away from the first movable block 25 is rotatably connected to the end of the second movable rod 27 away from the second movable block 251.

[0042] An extrusion rod 28 is rotatably installed at the connection between the first movable rod 26 and the second movable rod 27. A first elastic member 29 is sleeved on the outer surface of the positioning rod 23, and both ends of the first elastic member 29 are respectively connected to the opposite ends of the two second movable blocks 251. At the same time, the first elastic member 29 is in the middle position of the positioning rod 23.

[0043] Specifically, when the infrared detector module is placed between the two circular plates 24, the extrusion rod 28 is pressed to make the extrusion rod 28 move downward as a whole, and when the extrusion rod 28 moves, the first movable rod 26 and the second movable rod 27 installed at the end of the extrusion rod 28 are synchronously driven to move. Since the ends of the first movable rod 26 and the second movable rod 27 that are away from each other are respectively rotatably installed with the first movable block 25 and the second movable block 251, and the inner walls of the first movable block 25 and the second movable block 251 are slidably connected to the outer surface of the positioning rod 23, when the extrusion rod 28 moves downward, the first movable rod 26 and the second movable rod 27 are cooperated to drive the first movable block 25 and the second movable block 251 to move to both sides.

[0044] At the same time, a first elastic member 29 is arranged between the two first moving blocks 25 and the second moving block 251, wherein the first elastic member 29 is an elastic component such as a spring. The two second moving blocks 251 are supported by the first elastic member 29, so that when the circular plate 24 is tightly pressed on the infrared detector module, it is supported by the first elastic member 29 to ensure overall stability.

[0045] Furthermore, a fixed column 12 is provided at the upper end of the operating platform 1 and on one side of the support plate 11, and a base plate 15 is provided on one side of the fixed column 12. A pressing block 14 is slidably installed at one end of the base plate 15, and a movable plate 16 is provided at the lower end of the pressing block 14. At the same time, an adjustment component 3 is provided at the lower end of the movable plate 16, and the installation component is positioned by the adjustment component 3.

[0046] Specifically, an arc-shaped plate is provided at one end of the bottom plate 15, and a guide block is provided on the inner wall of the arc-shaped plate. At the same time, the end of the guide block is in contact with the outer surface of the pressing block 14 to limit the movement of the pressing block 14 and avoid deviation from the set direction during movement.

[0047] Furthermore, a movable block 13 is rotatably mounted on one end of the bottom plate 15 and located above the pressing block 14 , and one end of the movable block 13 is rotatably connected to the upper end of the pressing block 14 .

[0048] A limit rod 17 is provided at the upper end of the operating platform 1 and between the support plate 11 and the fixed column 12 . The upper end of the limit rod 17 passes through and extends to one end of the movable plate 16 and is connected to the lower end of one side of the fixed column 12 .

[0049] Specifically, when the movable block 13 rotates, it pushes the pressing block 14 to move up and down. Since the lower end of the pressing block 14 is connected to the movable plate 16, it synchronously drives the movable plate 16 to move. At the same time, the running trajectory of the movable plate 16 is supported by the limit rod 17 to ensure that the movable plate 16 can move normally.

[0050] Furthermore, the adjustment assembly 3 includes a housing 31 connected to the movable plate 16 . A snap-fit ​​groove 32 is formed on the outer surface of the housing 31 , and an inner wall of the snap-fit ​​groove 32 is fitted with the lower end of the movable plate 16 .

[0051] The inner cavity of the housing 31 is provided with a driver 33. An adjustment plate 34 is provided at the output end of the driver 33. The outer surface of the adjustment plate 34 is slidably connected to the inner wall of the housing 31. A cross slot 341 is defined on the end of the adjustment plate 34 away from the driver 33. Multiple sets of adjustment rods 35 are rotatably mounted on the inner wall of the cross slot 341. These sets of adjustment rods 35 are evenly distributed along the inner wall of the cross slot 341. A clamping block 36 is rotatably mounted on the end of each adjustment rod 35 away from the adjustment plate 34.

[0052] In this embodiment, a slide groove is provided at the lower end of the movable plate 16, and a docking block is slidably installed on the inner wall of the slide groove. At the same time, the outer surface of the docking block is engaged with the inner wall of the engaging groove 32, and the entire adjustment assembly 3 is fixed by the docking block.

[0053] The driving member 33 is a device with a telescopic function, such as an electric telescopic rod, and is connected to an external control device, so that when the driving member 33 is started, it synchronously drives the adjustment plate 34 set at the output end of the driving member 33 to move. When the adjustment plate 34 moves, it drives the adjustment rod 35 installed on the inner wall of the cross groove 341 to move. Since the upper end of the adjustment rod 35 is rotatably connected to the clamping block 36, it drives the clamping block 36 to move synchronously.

[0054] Furthermore, a slot hole 38 corresponding to the cross slot 341 is defined at one end of the housing 31 , and an inner wall of the slot hole 38 is slidably connected to an outer surface of the engaging block 36 .

[0055] A positioning pin 39 is provided on one side of the clamping block 36, and one end of the positioning pin 39 is rotatably connected to the inner wall of the slot 38. A second elastic member 37 is provided on one end of the adjustment plate 34, and the end of the second elastic member 37 away from the adjustment plate 34 is connected to the inner wall of the housing 31.

[0056] Specifically, since a positioning pin 39 is provided on one side of the clamping block 36, when the adjusting rod 35 moves upward, the clamping block 36 is driven to rotate around the positioning pin 39, so that the end of the clamping block 36 is moved closer to the middle, and the components processed by the infrared detector module are pre-positioned. When the positioning is completed, the entire movable plate 16 is moved downward, so that the components of the infrared detector module are tightly fitted in the specified position, while ensuring the stability of the processing.

[0057] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0058] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
