Description

Technical Field

[0001] The utility model relates to the technical field of FA optical fiber jumper production, in particular to a jig for baking and cleaning. Background Art

[0002] FA fiber optic patch cables and arrayed fiber optic planar waveguides are precision transmission components used in the optical communications industry. They are typically made of quartz or borosilicate glass, with array spacing accuracy reaching 0.0005mm. The thinnest raw material thickness is only 0.15mm. The material is fragile, small, and thin, and requires extremely high cleanliness. Therefore, high-temperature sintering (to repair microcracks in the glass and carbonize organic matter) and cleaning (to remove surface contaminants) before assembly are particularly important. Because the high-temperature sintering reaches up to 500°C, and different carriers are used for both sintering and cleaning, the material undergoes two passes, increasing the risk of breakage and loss.

[0003] At present, the cleaning process industry generally adopts the following two processes; one is to use ultra-dense metal mesh in combination with beaker for cleaning. This cleaning method does not separate the glass pieces individually. Dozens or hundreds of glass pieces are easily overlapped after being washed and dried in a container. Glass pieces with a minimum size of 0.15mm are difficult to separate after overlapping, resulting in a high rate of product damage and scrapping; the other cleaning process that is more common in the industry is that the cleaning jig is made of round plastic material and is milled with grooves by CNC processing. Each glass piece is placed in a groove, but this cleaning process has the following disadvantages: (1) The existing jig glass pieces are placed vertically. This placement method is difficult to place with plastic tweezers or a suction pen, and the placement efficiency is low and the placement is difficult; (2) Since the material needs to be baked at high temperature after cleaning, although the plastic jig is heat-resistant to 200℃, it will be slightly deformed after a long baking time. In this way, the glass pieces will leak out through the deformation gap during the cleaning process. Moreover, since the glass pieces are too small, too thin and made of transparent material, it is difficult to find them in the container after leaking out of the jig, which eventually leads to the loss of raw materials.

[0004] In view of the deficiencies in the prior art, the present invention provides a jig for baking and cleaning to solve the technical problems in the above-mentioned background technology.

[0005] The utility model provides a jig for baking and cleaning, comprising a base, wherein the top surface of the base is formed with a plurality of sheet placement grooves arranged in an array for placing glass sheets to be baked and cleaned, and a plurality of through grooves connecting two adjacent sheet placement grooves, and the bottom of each sheet placement groove is provided with a through hole that penetrates the base.

[0006] Furthermore, the size of the sheet placing slot is larger than the size of the glass sheet to be baked and cleaned.

[0027] like Figure 1As shown, an embodiment of the present invention provides a jig for baking and cleaning, including a base 10, the top surface of the base 10 is formed with a plurality of sheet placement slots 11 arranged in an array for placing glass sheets to be baked and cleaned, and a plurality of through slots 12 connecting two adjacent sheet placement slots 11, and the bottom of each sheet placement slot 11 is provided with a through hole 13 passing through the base 10. Through the array-form sheet placement slots 11 and the through slots 12, on the one hand, the cleaning liquid can fully contact each piece of glass to achieve efficient surface cleaning, and on the other hand, the hot air is directly applied to the bottom of the glass sheet through the through hole 13, and combined with the top opening, a good convection environment is formed, which promotes rapid evaporation of moisture and ensures a fast and uniform drying effect.

[0028] In an embodiment of the utility model, when in use, the glass pieces to be baked and cleaned are placed one by one in the sheet placing grooves 11 on the base 10 to ensure that each piece of glass can be placed firmly and there is enough space between each other to facilitate the flow of cleaning liquid or gas. Specifically, for wet cleaning, an ultrasonic cleaning machine can be turned on to circulate the cleaning liquid between the sheet placing grooves 11, and the structure connected by the through grooves 12 promotes uniform distribution and flow of the liquid, so as to achieve effective cleaning of the surface of the glass pieces. After cleaning is completed, the liquid in the cleaning groove can be quickly emptied through the through hole 13; for the drying process, hot air or other drying medium can be introduced from the bottom through the through hole 13, and the principle of rising hot air is used to accelerate evaporation, while maintaining good ventilation between the glass pieces through the through grooves 12.

[0029] Specifically, in the embodiment of the present invention, the shapes of the plurality of sheet placement slots 11 may be the same or different, and the present disclosure does not intend to limit this. For example, the sheet placement slot 11 may be rectangular or have other shapes.

[0030] Specifically, in the embodiment of the present invention, the size of the sheet placing slots 11 is larger than the size of the glass sheets to be baked and cleaned. Since the size of the sheet placing slots 11 is larger than the glass sheets, the glass sheets to be cleaned can be easily placed in each sheet placing slot 11, and the larger space helps the operator to take and place the glass sheets more conveniently, and can prevent the glass sheets from being damaged due to misoperation to a certain extent. At the same time, the larger space of the sheet placing slots 11 allows more cleaning liquid or hot air to contact all surfaces of the glass sheets, thereby improving the cleaning and drying effects.

[0031] Specifically, in the embodiment of the present invention, the height of the top of the base 10 located at the edge of the sheet placement slot 11 is greater than the height of the glass sheet to be baked and cleaned, which is conducive to forming a more effective flow path for the cleaning liquid or hot air, especially when adjacent sheet placement slots 11 are connected through the through slot 12, more uniform cleaning or drying can be achieved.

[0032] Specifically, such as Figure 2 As shown, in an embodiment of the present invention, the base 10 includes a mounting end 14 and a fixed end 15 arranged on the top of the mounting end 14, and the sheet placement groove 11 is formed at the fixed end 15; there are a plurality of bases 10, and the plurality of bases 10 are arranged adjacent to each other in the vertical direction, and the bottom surface of the mounting end 14 of the base 10 arranged adjacent to each other and placed at the bottom is formed with a mounting groove 141 adapted to the fixed end 15. The multi-layer structure can process more glass sheets in a limited space, thereby improving the utilization rate per unit area, and the number of layers can be increased or decreased as needed to accommodate different numbers of glass sheets.

[0033] Based on the above scheme, if Figure 3-5 As shown, in an embodiment of the present invention, a cover plate 20 is further included that covers the fixed end 15 of the base 10. The cover plate 20 is provided with a plurality of slots 21, and the slots 21 are arranged corresponding to the sheet placement slots 11. Specifically, a docking slot 22 is formed on the top of the cover plate 20. When the docking slot 22 of the cover plate 20 is covered on the fixed end 15 of the base 10, the slots 21 can ensure that the cleaning liquid or hot air circulates between the sheet placement slots 11, thereby achieving effective cleaning or efficient drying.

[0034] Specifically, in the embodiment of the present invention, the base 10 and the cover plate 20 are both made of quartz material, so that they can be used for sintering and cleaning, thereby reducing the number of product turnovers.

[0035] The working process of the fixture provided in this implementation is as follows:

[0036] High temperature sintering: Use plastic tweezers to place the glass pieces to be sintered into the sheet placing slots 11, with one piece placed in each sheet placing slot 11. After one base 10 is full, overlap another base 10 and continue placing. After placing, cover it with a cover plate 20, and then place it in a Mabo furnace for baking and sintering at 500 degrees. The purpose of sintering is to repair the micro cracks inside the glass piece and the carbonization of organic matter on the surface, thereby improving product reliability and bonding ability.

[0037] Ultrasonic cleaning: The sintered glass piece together with the base 10 and the cover plate 20 are placed in an ultrasonic ultrasonic cleaning process. The first step is to use the cleaning liquid to clean for 10 minutes. After the cleaning is completed, the cleaning liquid is poured out and then used to clean 5 times with pure water, each time for 3 minutes, to rinse the cleaning liquid clean. Then, the cleaned glass piece together with the base 10 and the cover plate 20 are placed in an oven to dry. After drying, they are placed in a well-proportioned coupling agent and soaked for 15 minutes to enhance the adhesion of the materials. Finally, they are placed in an oven to dry to complete the ultrasonic cleaning process. During the whole process, the glass piece together with the base 10 and the cover plate 20 are moved as a whole, thereby reducing scrap and loss caused by collisions between materials during the turnover process.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
