Description

Technical Field

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

[0002] Infrared detectors are widely used in many fields, and their application scope may be further expanded in the future, such as automotive night vision, medical, energy, security and other fields. The vacuum packaging of infrared detectors is a relatively difficult packaging method. With the advancement of material science and technology and the continuous expansion of application scenario requirements, the vacuum packaging of infrared detectors may develop in the direction of smaller size and higher integration in the future. However, as the size of packaged devices decreases, the current packaging method of wire bonding chip interconnection will lead to a decrease in production speed and finished product yield, which guarantees the 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. In the process of using the packaging jig to package the infrared detector module, the packaging jig and packaging method for the infrared detector module greatly improve the packaging efficiency of the infrared detector module because the multiple mounting parts 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 part is much larger than the contact area when the tweezers are used to clamp, thereby improving the fixing reliability of each ceramic tube shell, avoiding the problem of poor packaging of the infrared detector module caused by jitter, 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 accurate enough, the detector module may be offset or unstable during the packaging process, affecting the packaging quality and consistency. At the same time, if the force of the jig to fix the detector module is too large or too small, it will cause problems. Excessive fixing force may cause damage or deformation of the detector component, while too small a force may cause the module to move or become unstable during the packaging process. If it cannot adapt to detector modules of different sizes, shapes or versions, the jig may need to be replaced or adjusted frequently, affecting production efficiency and the flexibility of the production line. Therefore, a packaging jig for infrared detector modules has been developed. Summary of the invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Example: See Figure 1-Figure 9 A packaging fixture for an infrared detector module includes an operating platform 1, a support plate 11 is arranged at the upper end of the operating platform 1, a limiting component 2 is arranged 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, a device with a telescopic function such as an electric telescopic rod is provided at the lower end of the support plate 11 and 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 opened 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, so that it can limit irregular parts.

[0039] Furthermore, the limiting assembly 2 includes two fixed blocks 21 connected to the support plate 11, limiting plates 22 are arranged on both sides of the upper ends of the two fixed blocks 21, a positioning rod 23 is arranged 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. A plurality of groups of first movable rods 26 are rotatably installed on the outer surface of the first movable block 25, and the plurality of groups of first movable rods 26 are evenly distributed on the outer surface of the first movable block 25.

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 first movable rod 26 and the second movable rod 27 are respectively rotatably installed at the ends away from each other 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 cooperate 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 cooperates with the first elastic member 29 to support it and ensure the 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, 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, a movable plate 16 is provided at the lower end of the pressing block 14, and 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 plate is provided at one end of the bottom plate 15, and a guide block is provided on the inner wall of the arc plate.

[0049] Specifically, when the movable block 13 rotates, the pressing block 14 is pushed to move up and down. Since the lower end of the pressing block 14 is connected to the movable plate 16, the movable plate 16 is driven to move synchronously. 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 , an outer surface of the housing 31 is provided with a snap-fitting groove 32 , and an inner wall of the snap-fitting 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 driving member 33, and an adjusting plate 34 is provided at the output end of the driving member 33, and the outer surface of the adjusting plate 34 is slidably connected to the inner wall of the housing 31. A cross slot 341 is provided at one end of the adjusting plate 34 away from the driving member 33, and a plurality of groups of adjusting rods 35 are rotatably mounted on the inner wall of the cross slot 341, and the plurality of groups of adjusting rods 35 are evenly distributed on the inner wall of the cross slot 341. A clamping block 36 is rotatably mounted at one end of each adjusting rod 35 away from the adjusting 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, the adjustment plate 34 arranged at the output end of the driving member 33 is synchronously driven to move, wherein when the adjustment plate 34 moves, the adjustment rod 35 installed on the inner wall of the cross groove 341 is driven to move, and since the upper end of the adjustment rod 35 is rotationally connected to the clamping block 36, the clamping block 36 is driven to move synchronously.

[0054] Furthermore, a slot hole 38 corresponding to the cross slot 341 is formed 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 clamping block 36 .

[0055] A positioning pin 39 is disposed 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 disposed on one end of the adjustment plate 34, and one 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 of the infrared detector module are pre-positioned. After 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 select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
