Description

Technical Field

[0001] The present invention relates to the technical field of electrochromic product detection, and in particular to a detection method of an electrochromic component, an electrochromic component and a glass product. Background Art

[0002] Electrochromic phenomenon refers to the phenomenon that electrochromic materials undergo stable and reversible color changes under the action of an external electric field. In order to improve the appearance of the product, laser scratching is usually performed on the surface of the electrochromic product to obtain the required pattern. However, the depth of the scratching is crucial to the performance of the product. If the scratching depth is too shallow, the direct edge connection between the upper conductive film and the bottom conductive film cannot be blocked, resulting in the risk of short circuit in the product. If the scratching depth is too deep, it will destroy the transmission of voltage on the bottom conductive film, causing the entire internal circuit of the product to be disconnected and the product to fail.

[0003] At present, there are generally two methods used to detect the scratch depth. The first is the step meter detection method. The step meter is a contact surface topography measuring instrument. Its measurement principle is: when the stylus of the step meter slides gently along the measured surface, due to the tiny peaks and valleys on the surface of the product, the stylus moves up and down along the peaks and valleys while sliding. The movement of the stylus can reflect the surface contour of the product and then feedback the scratch depth. The second is the microscope observation method, which uses a microscope to magnify a specific area on the surface of the product at a high power to observe the surface characteristics of the area.

[0004] However, the laser scribing travel is long, while the step meter and microscope can only detect a tiny area at a time, and the detection efficiency is extremely low. Summary of the invention

[0005] One object of the present invention is to provide a detection method for an electrochromic component to improve detection efficiency.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0037] like Figure 1 As shown, the detection method of the electrochromic component, the surface of the electrochromic component is provided with a laser-scribed groove 14, and the detection method comprises the following steps:

[0038] S100 , selecting a first conductive contact point and a second conductive contact point on the surface of the electrochromic component, wherein the first conductive contact point and the second conductive contact point are respectively located on two sides of the laser-scribed groove 14 .

[0039] S200, detecting the resistance value between the first conductive contact point and the second conductive contact point, and determining whether the resistance value is greater than a first preset value and less than a second preset value. If so, determining that the scratching depth of the laser-scribed groove 14 meets the requirement; if not, determining that the scratching depth of the laser-scribed groove 14 does not meet the requirement.

[0040] This embodiment can determine whether the scoring depth of the laser-scored groove 14 meets the requirements by detecting the resistance values ​​on both sides of the laser-scored groove 14. The detection efficiency is high, and there is no influence on the product properties during the detection process. The depth evaluation of the entire laser-scored groove 14 can be performed to quickly obtain the inspection results, which is beneficial to the production line monitoring during the production process and meets the production requirements of the electrochromic components.

[0041] Optionally, during the same detection process, the first conductive contact point and the second conductive contact point are located on the same cross-section of the electrochromic component. During the same detection process, it is ensured that the first conductive contact point and the second conductive contact point are located on the same cross-section of the electrochromic component to prevent detection errors caused by misalignment. For example, when the first conductive contact point and the second conductive contact point are misaligned, the distance between the first conductive contact point and the second conductive contact point increases, and the resistance value obtained by detection increases, resulting in misalignment judgment.

[0042] Optionally, in step S200, one of the positive bus bar 100 and the negative bus bar 200 of the resistance detection device is electrically connected to the first conductive contact point, and the other of the positive bus bar 100 and the negative bus bar 200 is electrically connected to the second conductive contact point.

[0043] The positive bus bar 100 and the negative bus bar 200 are used to contact the surface of the electrochromic component, thereby reducing surface damage to the electrochromic component, increasing the contact area, preventing contact point slippage during the detection process, and ensuring detection accuracy.

[0044] In the thickness projection direction of the electrochromic component, the laser-scribed groove 14 is linear, so that the positive bus bar 100 and the negative bus bar 200 are parallel to the laser-scribed groove 14, and the distance from each section of the positive bus bar 100 to the laser-scribed groove 14 is equal, and the distance from each section of the negative bus bar 200 to the laser-scribed groove 14 is equal, thereby ensuring detection accuracy.

[0045] Optionally, in step S200, during the detection process, the positive bus bar 100 and the negative bus bar 200 are both fixed to the surface of the electrochromic component to prevent contact point slippage during the detection process and ensure detection accuracy.

[0046] Optionally, before performing step S200, the surface of the electrochromic component is laser-scribed to obtain a color-changing separation groove 15 surrounding the laser-scribed groove 14, and the color-changing separation groove 15 separates the electrochromic component into an insulated and isolated color-changing functional area and a non-color-changing functional area. The laser-scribed groove 14, the first conductive contact point, and the second conductive contact point are all located in the color-changing functional area.

[0047] Optionally, the color-changing functional area includes a bottom transparent conductive film 11, an electrochromic film 12 arranged on the bottom transparent conductive film 11, and a surface transparent conductive film 13 arranged on the electrochromic film 12, the bottom transparent conductive film 11 includes a first covering area, a second covering area and an exposed area, the electrochromic film 12 covers the first covering area, and the edge of the surface transparent conductive film 13 extends to cover the second covering area.

[0048] Optionally, in step S100, a second conductive contact point is selected in the exposed area.

[0049] The present embodiment also provides an electrochromic component, which includes a bottom transparent conductive film 11, a surface transparent conductive film 13 and a surface transparent conductive film 13, wherein the bottom transparent conductive film 11 includes a first covering area, a second covering area and an exposed area; the electrochromic film 12 is deposited to cover the first covering area; the surface transparent conductive film 13 is deposited to cover the electrochromic film 12 and the second covering area; a laser-scribed groove 14 is provided on the surface of the electrochromic component, the opening of the laser-scribed groove 14 is located in the surface transparent conductive film 13, the depth direction of the laser-scribed groove 14 points from the surface transparent conductive film 13 to the bottom transparent conductive film 11, and the depth of the laser-scribed groove 14 is detected by the above detection method to ensure the acquisition of high-quality electrochromic components and prevent defective products from leaving the factory.

[0050] like Figure 2 As shown, this embodiment also provides a glass product, which includes a glass layer 16 and the electrochromic component as above, the electrochromic component is deposited on one side of the glass layer 16, and along the thickness direction of the glass layer 16, the bottom transparent conductive film 11, the electrochromic film 12 and the surface transparent conductive film 13 are arranged in sequence from near to far.

[0051] Optionally, the material of the glass layer 16 is indium tin oxide.

[0052] In the production process of glass products, a layer of ITO film is first deposited on the surface of the glass layer 16, and the ITO film forms the bottom transparent conductive film 11, and then the electrochromic film 12 is deposited on the first coverage area of ​​the bottom transparent conductive film 11, and finally an ITO film is deposited on the surface of the electrochromic film 12, and the ITO film forms the surface transparent conductive film 13. Due to the overlap of the coating edges, the edge of the surface transparent conductive film 13 overlaps with the second coverage area of ​​the bottom transparent conductive film 11, and then the electrochromic film 12 is completely covered, and the color-changing functional area is laser engraved. After scratching, a laser-scribed groove 14 is obtained, and a first conductive contact point and a second conductive contact point are selected on both sides of the laser-scribed groove 14 respectively. If the depth of the laser-scribed groove 14 is too shallow and fails to cut off the surface transparent conductive film 13, the measured resistance value is the resistance value of the surface transparent conductive film 13, and the resistance value is less than the first preset value. If the depth of the laser-scribed groove 14 is too deep, it not only cuts off the surface transparent conductive film 13 and the electrochromic film 12, but also extends to the bottom transparent conductive film 11 or even cuts off the bottom transparent conductive film 11, then the measured resistance value is greater than the second preset value.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention.
