Description

Technical Field

[0001] The present application relates to the technical field of coating jigs, and in particular to a carrier jig used for coating a part to be coated. Background Art

[0002] Electrochromism refers to the phenomenon that the color characteristics of a material undergo reversible changes under the action of an applied voltage, which manifests itself in the form of reversible changes in the color and transparency of the material.

[0003] At present, electrochromic devices have been widely used, such as electrochromic glasses, electrochromic energy-saving windows, anti-glare rearview mirrors, aircraft windows, etc. The general coating process of existing electrochromic devices is: first, a glass substrate for coating is provided, and then a first transparent conductive layer is plated on the glass substrate, and then the glass substrate is taken out, and a P1 line is made on the first transparent conductive layer with a laser, that is, a P1 groove is made on the edge of the first transparent conductive layer with a laser that penetrates the first transparent conductive layer, and then subsequent electrochromic layers, ion conduction layers, cation storage layers, and second transparent conductive layers are plated, thereby completing the coating process of the electrochromic device.

[0004] The purpose of forming the P1 groove in the first transparent conductive layer is to lead out the positive electrode to connect the electrochromic layer. However, there are many disadvantages in using laser lines to punch the P1 groove. First, there is a risk of glass edge collapse when using laser lines to punch the P1 groove in the first transparent conductive layer. Second, after the P1 groove is formed, it is cleaned first. If the cleaning is not done properly, dirt will be generated to affect the subsequent coating, and there will also be coloring or white spots in the P1 groove, affecting the material performance. Third, the formation of the P1 groove will destroy the integrity of the device and there is a risk of accelerated oxidation of the device. Utility Model Content

[0031] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0032] In the current electrochromic device coating process, it is necessary to first coat the first transparent conductive layer on the glass substrate, and then use a laser to punch a P1 line (i.e., a P1 groove) that penetrates the first transparent conductive layer on its edge to lead out the positive electrode and connect the electrochromic layer. However, when using laser to punch the P1 groove, there will be a risk of edge collapse of the glass substrate, and the formation of the P1 groove will produce dirt that affects the subsequent coating if it is not cleaned properly, and there is a risk of accelerated oxidation of the device.

[0033] Based on this, according to one embodiment of the present disclosure, Figure 1-2 As shown, the utility model discloses a supporting fixture for coating a workpiece to be coated, comprising a substrate 1; an opening 2, the opening 2 is opened on the substrate 1, and the opening 2 is adapted to the shape of the workpiece 4 to be coated; a rib 3, the rib 3 is formed in the circumferential direction of the opening 2 and extends toward the center direction of the opening 2; the rib 3 cooperates with the opening 2 to support the workpiece 4 to be coated and shield the edge area of ​​the workpiece 4 to be coated.

[0034] The present application designs a bearing fixture for coating the part to be coated. By setting the retaining edge 3, the P1 groove area can be shielded when the part to be coated 4 is specifically coated, and the P1 groove is formed at the same time as the first transparent conductive layer on the part to be coated 4 is formed. Thereby omitting the current process of using a laser to punch a P1 groove on the already formed film layer when coating the part to be coated 4, thereby improving the coating efficiency. It also avoids the hidden danger of edge collapse of the part to be coated 4 when using a laser to punch the P1 groove. In addition, since there is no need to use a laser to form the P1 groove, there is no subsequent groove cleaning process, which improves the coating efficiency while avoiding dirt caused by improper cleaning and affecting the subsequent coating. And since there is no need to use a laser to form the P1 groove, the integrity of the film layer on the part to be coated 4 is guaranteed, and the oxidation rate of the part to be coated after the coating is completed is slowed down.

[0035] For example, in the present application, the part to be coated 4 is used as the base material of the electrochromic device, and its material can be flexible ultra-thin glass. By coating different film layers on the part to be coated 4, the preparation of the electrochromic device can be realized, for example, eyeglass lenses, electrochromic energy-saving windows, anti-glare rearview mirrors, aircraft windows, etc. can be prepared, so the shape of the opening 2 on the substrate 1 can be opened according to the shape of the specific part to be coated 4.

[0036] like Figure 3-4 As shown, in this embodiment, the object to be coated 4 is a lens made of flexible ultra-thin glass, and the shape of the opening 2 is adapted to the shape of the lens.

[0037] For example, in this embodiment, the rib 3 is formed in the circumferential direction of the opening 2 and extends toward the center direction of the opening 2. Therefore, the shape of the rib 3 is also substantially similar to the shape of the part to be coated 4. When the part to be coated 4 is placed on the opening 2, the rib 3 supports the part to be coated 4 to prevent it from falling off, and the opening 2 further limits the movement of the part to be coated 4 in the horizontal direction.

[0038] The rib 3 can be formed from the inner wall surface of the opening 2 in the circumferential direction of the opening 2 and extend toward the center direction of the opening 2, so as to cooperate with the opening 2 to carry the part to be coated 4 and shield the edge area of ​​the part to be coated 4, thereby shielding the P1 line area when the part to be coated 4 is coated; therefore, the connection position between the rib 3 and the opening 2 can be located on the inner wall surface of the opening 2.

[0039] For example, the rib 3 may be formed on one of the side surfaces of the substrate 1, surrounding the opening 2 and extending toward the center of the opening 2. The rib 3 is formed on the side surface of the substrate to facilitate processing. Figure 5-8 As shown, the rib 3 is formed on one side of the substrate 1, surrounds the opening 2 and extends toward the center of the opening 2. The rib 3 is connected to one of the port edges of the opening 2, so that the rib 3 and the opening 2 form a step structure for supporting the piece 4 to be coated. And the plane where the lower side 33 of the rib 3 is located is on the same plane as one of the side surfaces of the substrate 1, as shown in FIG. Figure 8 As shown, the rib 3 partially overlaps with and is connected to the inner wall surface of the opening 1 in the thickness direction.

[0040] For example, the upper side edge 34 of the rib 3 is arranged parallel to the surface of the substrate 1 , which facilitates the processing of the rib on the one hand, and enables the workpiece 4 to be placed on the rib 3 stably without shaking on the other hand.

[0041] For example, when the part to be coated 4 is placed in the opening 1, in order to smoothly take out the part to be coated 4 after the coating is completed, and if the part to be coated 4 is made of ultra-thin flexible glass, in order to prevent the part to be coated 4 from being squeezed and deformed when placed in the opening, a pick-and-place gap needs to be reserved between the part to be coated 4 and the opening 1, and the pick-and-place gap is generally 0.2±0.005mm.

[0042] In one embodiment, the rib 3, the opening 2 and the substrate 1 are an integrally formed structure. The integrally formed part is simple and convenient to manufacture, and ensures the strength of the connection position between the rib 3 and the opening 2. The substrate 1 and the rib 3 can be made of titanium alloy.

[0043] In one embodiment, the width of the rib 3 is 0.6±0.05 mm. Further, we use the supporting fixtures with different rib 3 widths to carry the parts to be coated 4 (taking the parts to be coated as lenses as an example for experimental coating) for coating, and the coating effects of the parts to be coated 4 are different, as shown in Table 1.

[0044] Table 1 Coating effect of the coating workpiece 4 carried by the supporting fixture with different rib widths

[0045] Rib width(mm) 1.5 1 0.6 Coating effect (mm) 2.8 1.7 1.2

[0046] Among them, in Table 1, the coating effect refers to the width of the ineffective edge of the lens. It can be seen from Table 1 that as the width of the rib 3 increases, the width of the ineffective edge of the lens after coating will also increase, and when the rib width is 1 to 1.5 mm, the screen-printed silver paste will penetrate the film layer after the lens is coated, resulting in no color change of the electrochromic layer. However, limiting the rib width of the present application to the range of 0.6 ± 0.05 mm can not only make the width of the ineffective edge of the lens after coating within a suitable range, but also ensure the coating effect of the lens.

[0047] In one embodiment, the corners of the retaining edge 3 away from the piece to be coated 4 are provided with a chamfer, and the chamfer angle is 30°±0.5°. Figure 8 As shown, the retaining edge 3 has a first corner 31 and a second corner, the first corner 31 is arranged close to the workpiece 4 to be coated (the close and far here refer to the positional relationship between the workpiece 4 to be coated and the corners of the retaining edge 3 when the workpiece 4 to be coated is placed on the opening 2), and the second corner is arranged away from the workpiece 4 to be coated (the second corner is arranged close to the coating equipment). In order to prevent uneven film layer on the workpiece 4 to be coated during coating, that is, to prevent the film layer material from piling up at the second corner position when the workpiece 4 to be coated is coated to produce a piling peak, the second corner away from the workpiece 4 to be coated is set to a chamfer 32, and the chamfer angle is 30°±0.5°.

[0048] In one embodiment, Figure 4 , Figure 7 As shown, the carrier fixture of the present application further includes a fixing member 5 , which is detachably connected to the substrate 1 , and is used to fix the part to be coated 4 in the opening 1 .

[0049] Since the opening 1 and the rib 3 cooperate to carry the workpiece 4 to be coated, when the workpiece 4 to be coated is placed on the step formed by the opening 1 and the rib 3, the top of the workpiece 4 to be coated may or may not protrude from the end of the opening. For example, when the top of the workpiece 4 to be coated protrudes from the end of the opening, the fixing member 5 may be configured as an arc-shaped, downwardly convex elastic sheet, one end of which is fixed on the substrate, and the other end has a downward elastic force on the workpiece 4 to be coated, so that the workpiece 4 to be coated is fixed on the step. For example, when the top of the workpiece 4 to be coated does not protrude from the end of the opening 1, as shown in FIG. Figure 7 As shown, the fixing member 5 can be a rigid fixing plate, and a long hole 51 is opened on the fixing member, and a screw 52 passes through the long hole 51 and is threadedly connected to the substrate 1, so that the fixing member 5 is restricted on the substrate 1. Therefore, before the coating, the screw 52 can be slightly rotated to release the fixing of the fixing member 5. When the workpiece 4 to be coated is placed on the step, the fixing member 5 is pushed so that one end of the fixing member 5 extends toward the workpiece to be coated and presses the workpiece 4 to be coated, and then the screw 52 is rotated to fix the fixing member 5 on the substrate 1. The fixing member 5 can be set on the surface of the substrate 1, or a mounting groove can be opened on the substrate 1 to install the fixing member 5, which can be determined according to the distance between the top of the workpiece 4 to be coated and the end of the opening.

[0050] In one embodiment, Figure 1 As shown, the carrier jig of the present application also includes a frame 6, a substrate 1 is provided in the frame 6, and the frame 6 and the substrate 1 are detachably connected. The material of the frame 6 and the substrate 1 can be titanium alloy. The frame 6 is used to fix the substrate 1, so a plurality of substrates 1 can be provided in the frame 6, so that a large number of parts 4 to be coated can be coated at the same time. The substrate 1 and the frame 6 are detachably connected, for example, the connection between the substrate 1 and the frame 6 can be achieved by a connector 61, or it can be a snap-on connection between the substrate 1 and the frame 6. The detachable connection between the substrate and the frame can be achieved by using existing known technologies, which will not be described in detail here.
