Description

Technical Field

[0001] This utility model belongs to the technical field of photoelectric detector component assembly and packaging technology, and relates to a tooling for reducing the damage rate of glass light window cover plates of irregularly shaped photoelectric detectors. Background Technology

[0002] Glass light window covers are used in irregularly shaped photodetectors to receive optical signals in specific wavelength bands and protect the internal components of the photodetectors. They are crucial for maintaining the vacuum or hermetically sealed packaging of irregularly shaped photodetectors. The irregular shape and insufficient rigidity of the glass light window cover material make it prone to deformation and damage during transportation, affecting the photoelectric performance of the photodetector components. Traditional single-pack, independent foam packaging results in excessively large packaging volumes, hindering cost reduction. Furthermore, before welding the glass light window cover, a high-temperature purification process is required to remove particles and moisture from the surface. Directly placing the cover in the high-temperature purification equipment easily scratches the surface metal coating, and manual one-to-one handling is unsuitable for large-scale production. Therefore, a specialized tooling suitable for the characteristics of irregularly shaped photodetector light window covers needs to be designed to reduce the damage rate and achieve efficient transportation, storage, and production of these covers.

[0022] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0023] like Figures 1 to 4 As shown, the tooling for reducing the damage rate of the glass light window cover of the irregularly shaped photodetector in this embodiment includes a base 1 and a cover plate placement platform 2. The cover plate placement platform 2 is arranged on the base 1, and two rows of hollow holes 3 are opened on the cover plate placement platform 2. The glass light window cover of the irregularly shaped photodetector is placed in the hollow holes 3.

[0024] The lower part of each hollow hole 3 is a cuboid groove 5, and the opening of the cuboid groove 5 is a square pyramidal opening 4.

[0025] The base 1 provides mechanical support for the glass light window cover plate placed on the platform 2, ensuring the tooling is placed stably. The base 1 has a stepped structure with a hollowed-out central section, which acts as a shock absorber to prevent deformation of the glass light window cover plate caused by vibration during transportation.

[0026] The base 1 has a length, width, and height of 140mm, 94mm, and 4mm, respectively. All four right angles of the base 1 are designed with an R0.5 chamfer to prevent the components from being scratched by sharp right angles during transportation, storage, and assembly packaging processes.

[0027] The hollowed-out structure in the middle of base 1 has a length, width, and depth of 116mm, 90mm, and 5mm, respectively, and is located at the center of base 1.

[0028] The cover plate placement stage 2 is used to place the glass light window cover plate of the irregularly shaped photodetector. It is integrated with the base 1 and located in the center of the base 1. The cover plate placement stage 2 is 135.6 mm long and 89.6 mm wide. The distance from the long side and the short side of the cover plate placement stage 2 to the edge of the base 1 is 2.2 mm.

[0029] The cover plate placement platform 2 has two rows of hollow holes 3, with 21 holes in each row, for a total of 42 hollow holes 3, which are used to place 42 irregularly shaped detector glass light window cover plates.

[0030] The glass light window cover plate is placed with its long side facing down in the hollow hole 3 in the cover plate placement platform 2, and the glass light window cover plate is completely covered by the hollow hole 3.

[0031] The center-to-center distances of each hollow hole 3 are 37.6 mm and 4.9 mm, respectively. The distances from the outermost hollow hole 3 to the long and short sides of the cover plate placement platform 2 are 3 mm and 10 mm, respectively. The cuboid groove 5 has a depth of 9 mm and a length and width of 32 mm and 1.5 mm, respectively.

[0032] The short side length and width of the open quadrangular pyramid 4 are the same as those of the cuboid slot 5. The length, width, and depth of the long side are 33mm, 2.0mm, and 0.5mm, respectively, and it adopts a C0.5 chamfer design. The horizontal and vertical spacing of each cuboid slot 5 is 5.4mm and 4.9mm, respectively.

[0033] The fixture is placed on the table, with the long and short sides of the irregularly shaped photodetector glass window cover plate parallel and perpendicular to the fixture, respectively, and placed downwards into the hollow hole 3. The glass structure is completely covered by the cuboid groove 5, and part of the metal structure of the glass window cover plate is placed in the pyramidal opening 4. The width of the glass window cover plate is smaller than the width of the pyramidal opening 4. During handling, tweezers or other handling tools are inserted into the pyramidal opening 4 to grasp the edge of the metal structure of the glass window cover plate and remove the glass window cover plate. The size of the pyramidal structure 4 is adapted to the handling tools, without damaging the metal coating and glass surface of the glass window cover plate, making the operation simple. During transportation and packaging, the base 1 directly contacts the box and equipment table surface, and the hollow structure at the bottom of the base 1 acts as a shock absorber. This fixture can place irregularly shaped detector glass window cover plates in large quantities for transportation and packaging of irregularly shaped photodetector assemblies, effectively reducing the damage rate of irregularly shaped photodetector glass window cover plates during transportation and handling. The tooling is made of engineering plastic, which will not damage the glass window cover, is resistant to high temperature and acid and alkali corrosion, is not easily deformed, and can be reused.

[0034] As can be seen from the above technical solution, this utility model can be used for the mass production, transportation, storage, and assembly packaging of irregularly shaped photodetector glass light window covers. The tooling has a four-sided pyramidal opening for matching clamping tools, preventing scratches on the metal plating and glass surface of the light window cover. The glass light window cover is tightly encased by the hollow holes in the tooling, and the base has a shock-absorbing structure to prevent deformation of the light window cover during transportation. The tooling of this utility model is made of engineering plastic, which has the advantages of low cost and reusability. This fixture improves the efficiency and reliability of transportation and production of irregularly shaped photodetectors and reduces the damage rate of glass light window covers.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
