Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass fixtures, in particular to a glass cleaning and electroplating fixture. Background Art
[0002] There are two main ways to clean glass, namely ultrasonic cleaning and flat cleaning equipment cleaning.
[0003] Ultrasonic cleaning method, before cleaning, the glass needs to be inserted into the loading rack, and the glass is placed in the ultrasonic cleaning equipment together with the loading rack for cleaning. After cleaning, the glass needs to be taken out from the loading rack and clamped one by one on the special electroplating fixture for electroplating. In the process of inserting and removing the rack, it is easy to cause secondary contamination and scratches on the glass, and the glass that has been ultrasonically cleaned is prone to dry watermarks. In the subsequent electroplating process, the dry watermarks produced by the glass during the ultrasonic cleaning process will cause electroplating discoloration. After ultrasonic cleaning, the glass product is clamped to the electroplating fixture for the second time after cleaning, and electroplated, the yield rate is 60%-70%.
[0004] Flatbed cleaning equipment will not produce dry watermark defects. During the cleaning process, rollers will transfer the glass in the cleaning equipment. Since there is a certain distance between the rollers, small-sized glass such as fingerprint recognition lenses, watch mirrors, camera protection covers, etc., cannot be transferred in the equipment through rollers because their size is too small relative to the roller spacing. Therefore, small-sized glass cannot be cleaned using flatbed cleaning equipment. Utility Model Content

[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.
[0031] The utility model is suitable for the flat plate cleaning and electroplating process of small-sized glass. The batch clamping and flat plate cleaning of multiple small-sized glasses can be realized through the jig. No secondary clamping is required after cleaning. The glass directly enters the electroplating link together with the jig, thus avoiding pollution and scratches on the glass caused by secondary clamping.
[0032] Hereinafter, "glass cleaning and electroplating jig" and "jig" refer to the jig product provided by the present utility model.
[0033] like Figure 1-2As shown, the glass cleaning and electroplating jig provided by the solution of the utility model includes a base plate 1, and the base plate 1 includes a base layer and a high-temperature and corrosion-resistant layer in sequence from the inside to the outside, and a plurality of through holes 2 are arranged at intervals on the base plate 1, and the inner wall of the through hole 2 is provided with a support beam 3 spanning the through hole 2, and the upper surface of the support beam 3 is provided with a tray 4 for carrying glass, and the tray 4 is fixedly connected to the support beam 3, and the upper surface of the tray 4 is higher than the upper surface of the base plate 1, and a plurality of positioning blocks 5 for fixing glass are arranged around each of the through holes 2 on the base plate 1, and the upper surface of the positioning block 5 is lower than the upper surface of the glass fixed on the tray 4.
[0034] The glass cleaning and electroplating jig of the utility model is applied to the flat plate cleaning and electroplating process. In the flat plate cleaning process, the jig needs to be in contact with acidic and alkaline cleaning agents, and in the electroplating process, the jig will be placed in a high-temperature electroplating environment, so the jig needs to be able to resist high temperature and acid and alkali corrosion. In the embodiment of the utility model, the use environment requirements are met by coating a high-temperature resistant and corrosion-resistant layer on the outside of the jig base. In some embodiments of the utility model embodiment, the material of the high-temperature resistant and corrosion-resistant layer is silicon nitride. Silicon nitride is an important inorganic non-metallic material and belongs to a kind of ceramic material. Silicon nitride has excellent physical and chemical properties, such as high hardness, high melting point, good thermal stability, oxidation resistance, corrosion resistance, and good mechanical strength and fracture toughness. A silicon nitride film is coated on the surface of the base of the jig, so that the jig can still maintain a stable structure in the cleaning equipment and electroplating equipment, and the silicon nitride film has a low hardness, which can prevent the glass from being clamped on the jig and causing scratches, so that the jig can be used in the cleaning process and the electroplating process at the same time, which is a breakthrough in the traditional use scenario of the jig.
[0035] Since the high temperature and corrosion resistant layer is arranged outside the base layer, the base layer can be made of relatively more materials, and only needs to meet certain high temperature resistance and non-deformation requirements. In the embodiment of the utility model, the material of the base layer includes aluminum, plastic, and bakelite.
[0036] The through hole 2 is used to accommodate the glass product, the support beam 3 is used to fix the tray 4, the tray 4 is used to carry the glass, and the positioning block 5 is used to fix the corners of the glass product. The design of the through hole structure can drain water in time during cleaning, which is convenient for air drying and will not produce poor dry watermarks. During electroplating, the upper surface and side surfaces of the glass need to be electroplated, so it is necessary to ensure that the upper surface and side surfaces of the glass can be thoroughly cleaned. In the embodiment of the utility model, the glass is lifted by the tray 4, and the upper surface of the positioning block 5 is lower than the upper surface of the glass fixed on the tray 4, so that the entire glass is located outside the upper surface of the fixture, and the upper surface and side surfaces are in full contact with the cleaning liquid, which can maximize the cleaning effect of the side edges of the glass product, and during electroplating, the upper surface and side surfaces can be fully exposed to the electroplating equipment to achieve a good electroplating effect.
[0037] like Figure 1-12 As shown, in the embodiment of the utility model, the support beam 3 is in the shape of a strip, and the support beam 3 is located on the center line of the through hole 2. The support beam 3 is designed to be in the shape of a strip, and coincides with the center line of the through hole, so that the whole structure is better balanced. The lower surface of the support beam 3 is flush with the lower surface of the base plate 1, and the height of the support beam 3 is less than the height of the inner wall of the through hole 2. The tray 4 is arranged at the center position of the upper surface of the support beam 3, and the support beam 3 and the tray 4 are fixedly connected by a columnar structure. The support beam 3 is flush with the lower surface, which increases the contact area between the jig and the flat cleaning device, so that the jig can be more smoothly transferred in the flat cleaning device. The height of the support beam 3 is less than the height of the inner wall of the through hole 2, and a height space is reserved for the tray 4. The columnar structure is used to fix the tray 4 and the support beam 3, and to increase the height of the tray 4. The utility model does not limit the specific shape of the columnar structure, for example, it can be a cylinder or a prism.
[0038] The tray 4 is used to carry the glass. When in use, the glass and the tray 4 are fixed by a high temperature resistant double-sided tape or glue. The tray 4 is an axisymmetric figure, symmetrical about the center line of the support beam 3. The symmetrical design can maximize the balance of the glass. The utility model does not limit the shape of the tray 4. In some embodiments of the utility model, the tray 4 is square, and in other embodiments of the utility model, the tray 4 is round.
[0039] In order to prevent the glass from loosening during the cleaning process due to the pressure of the cleaning nozzle or the lack of adhesion, in the embodiment of the utility model, a plurality of support blocks 6 are arranged on the inner wall of the through hole 2, the lower surface of the support block 6 is flush with the lower surface of the bottom plate 1, and the upper surface of the support block 6 is lower than the upper surface of the tray 4. Figure 7-8As shown, two support blocks 6 are arranged on both sides of the support beam 3. When the glass is accidentally loosened and tilted, the support blocks 6 and the tray 4 support the glass together to prevent the glass from falling into the gap of the roller of the flat cleaning equipment.
[0040] In the embodiment of the utility model, the part where the positioning block 5 contacts the glass is a concave surface, and the shape of the concave surface matches the shape of the edge of the through hole 2 near the positioning block 5. The specific number and position of the positioning blocks can be set according to the size and shape of the product. Figure 1-2 As shown in FIGS. 7-8 , in some embodiments of the present utility model, the through hole 2 is a rounded rectangle, and there are four positioning blocks 5 , which are respectively located at the four corners of the through hole 2 .
[0041] In the embodiment of the utility model, the outer frame of the bottom plate 1 is rectangular. By setting the jig as a rectangular outer frame, a jig with a regular outer frame edge can be obtained, and the jig can be arranged more closely on the roller of the flat cleaning device, effectively utilizing the space on the roller and improving the cleaning efficiency.
[0042] The glass cleaning and electroplating fixture provided by the present invention is used as follows:
[0043] (1) Use a glue dispenser to evenly apply glue to the pallet, or stick high-temperature resistant double-sided tape on the pallet.
[0044] (2) The glass is automatically pressed into the jig by a machine, or the glass is manually placed into the jig, with the side to be electroplated facing up and the other side glued with glue or double-sided tape.
[0045] (3) Check whether the glass is firmly attached and manually reinforce any loose glass.
[0046] (4) Place the fixture in a flat cleaning device for cleaning.
[0047] (5) After cleaning, use a robotic arm or manually remove the fixture and place it in the electroplating equipment. Be careful not to touch the glass during the process.
[0048] (6) After the electroplating is completed, the jig is removed from the electroplating equipment.
[0049] (7) Deactivate the glue on the fixture tray and remove the glass.
[0050] It should be specially noted that the glass cleaning and electroplating jig provided by the utility model is suitable for cleaning a variety of small-sized glass products such as fingerprint identification lenses, watch mirrors, and camera protection covers. The shape and size of the through holes used to accommodate glass products are adapted according to the shape and size of the specific glass products. The glass products include flat glass products and 3D glass products. The specific size of the jig and the number of through holes can be determined in combination with factors such as the size of the roller area of the flat cleaning equipment, the shape and size of the glass product, and the size of the operating area of the electroplating equipment, taking into account both efficiency and ease of operation. Figure 1-2 As shown, the fixture is provided with 6 through holes in the shape of rounded rectangles, and the 6 through holes form a structure of 3 rows and 2 columns, which can be used for fingerprint recognition lenses. In other embodiments of glass products, optionally, the through holes are circular in shape, and the number is 9, forming a through hole structure of 3 rows and 3 columns.
[0051] like Figure 1-12 The length and width of the fixture base plate 1 are 158 mm and 79 mm respectively, the length and width of a single through hole 2 are 42 mm and 36 mm respectively, the height of the inner wall of the through hole 2 is 3 mm, the width and height of the support beam 3 are 2 mm and 2.5 mm respectively, the length and width of the tray 4 are 5 mm and 3.93 mm respectively, the height of the positioning block 5 is 1 mm, and the height of the support block 6 is 2.5 mm.
[0052] When ultrasonic cleaning is used to clean and electroplate glass products, it is easy to produce dry watermark defects due to ultrasonic cleaning, and after ultrasonic cleaning, the glass needs to be clamped again and transferred to a special electroplating fixture. In this process, the glass will be contaminated and scratched. Finally, after electroplating, the yield of the glass product is only 60%-70%. However, by using the glass cleaning and electroplating fixture provided by the embodiment of the utility model, the glass can be flat-plate cleaned together with the fixture, and directly enter the electroplating equipment after cleaning. The surface of the glass cleaned by the flat plate has high cleanliness and no dry watermark defects, which can minimize the film defects after electroplating. After the electroplating is completed, the yield of the glass product is higher than 90%.
[0053] The glass cleaning and electroplating jig provided by the utility model comprises a bottom plate, which is provided with a base layer and a high temperature corrosion resistant layer for resisting acid, alkali and high temperature environment during electroplating from the inside to the outside, a plurality of through holes are opened on the bottom plate, a support beam is provided in the middle of the through hole, a tray for carrying glass is provided on the support beam, the tray pushes the glass out of the jig, positioning blocks for fixing the glass are provided along the four sides of the through hole on the upper surface of the bottom plate, a support block is provided on the inner wall of the through hole to prevent the glass from falling from the through hole into the gap of the roller of the flat cleaning equipment. The glass can be clamped on the jig to achieve flat cleaning, the upper surface and the side of the glass can be thoroughly cleaned, and the glass is electroplated together with the jig after cleaning, avoiding the pollution and scratches caused by the secondary clamping to the glass. Compared with electroplating after ultrasonic cleaning, the process flow is simplified and the product yield is improved.
[0054] The embodiments of the utility model are described above in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the utility model, ordinary technicians in this field can also make many forms of deformation without departing from the scope of protection of the utility model and the claims, which all fall within the protection of the utility model.
