Description

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0039] Specifically, if Figure 1-Figure 2As shown, a solar film 900 detection device is provided in an embodiment of the present application. The solar film 900 detection device mainly detects the transmittance on the solar film 900 to determine whether it meets the transmittance requirements of the solar film 900. In order to detect the transmittance, the device needs to illuminate the solar film 900 with specific light and detect the corresponding transmittance efficiency. Therefore, it is necessary to avoid interference from other light. In order to avoid this situation, an upper cover 100 and a lower cover 200 are provided in the embodiment of the present application. The upper cover 100 and the lower cover 200 are connected together for use. The solar film 900 is installed in a darkroom 700 formed by the upper cover 100 and the lower cover 200. Specifically:

[0040] The matching connection between the upper cover 100 and the lower cover 200 is connected through a positioning piece 1100. Positioning grooves 1200 are respectively opened on the upper cover 100 and the lower cover 200 at positions corresponding to the positioning piece 1100. The positioning piece 1100 is located in the positioning groove 1200, so that the upper cover 100 and the lower cover 200 can be connected through the positioning piece 1100, which is convenient for forming a darkroom 700 to avoid the influence of ambient light.

[0041] Preferably, the positioning member 1100 can be configured as a magnetic adsorption member, and the upper cover 100 and the lower cover 200 can be matched and installed through magnetic adsorption to achieve the positioning purpose, thereby facilitating the formation of the darkroom 700 and avoiding interference from ambient light.

[0042] Preferably, the positioning member 1100 can be configured as a snap-fit configuration, which is disposed at the outer sides of the upper cover 100 and the lower cover 200 to match the upper cover 100 and the lower cover 200 through the connection effect of the snap-fit.

[0043] During the inspection, the solar film 900 needs to be placed in the dark room 700 to facilitate the inspection of the solar film 900. Figure 1-Figure 3 As shown, a groove 220 is provided on one side of the lower cover 200 facing the upper cover 100, and a support surface 710 is formed at the bottom of the groove 220, and the support surface 710 is used to support the solar film 900. Specifically, for the support surface 710, preferably, in this application, the thickness of the groove 220 can be selected to be equal to the thickness of the solar film 900, so that the solar film 900 on the support surface 710 can be clamped by the upper cover 100 and the lower cover 200, which is convenient for detecting the solar film 900.

[0044] Preferably, in the present application, the depth of the groove 220 is equal to the sum of the thicknesses of the solar film 900 and the glass 1000, so that the glass 1000 and the solar film 900 can be clamped by the upper cover 100 and the lower cover 200, which is more in line with the actual test scenario. At the same time, in order to avoid the influence of the thickness of different types of glass 1000 and solar film 900 and the inability to clamp, preferably, as shown in FIG. Figure 3As shown, in the embodiment of the present application, a spring 230 and a support plate 240 are provided on the lower cover 200, and the top position of the support plate 240 cooperates with the lower cover 200 to form the groove 220 to accommodate different types of glass 1000 and solar film 900 for easy clamping.

[0045] An emitting device 300 and a receiving device 400 are provided in the darkroom 700. Under the existing technology, the emitting device 300 and the receiving device 400 are respectively provided on both sides of the solar film 900, so that the detected light only passes through the solar film 900 once, resulting in errors in the detection accuracy, which affects the actual effect of the product.

[0046] In order to avoid the above-mentioned influence in the present application, it is preferred that both the transmitting device 300 and the receiving device 400 are arranged on one side of the solar film 900, so that the detection light passes through the solar film 900 twice to improve the detection accuracy.

[0047] To achieve the above effect, this application provides multiple embodiments based on the above structure to implement this process, specifically:

[0048] First embodiment:

[0049] like Figure 5-Figure 6 As shown, a transmitting device 300 and a receiving device 400 are provided. Both the transmitting device 300 and the receiving device 400 are provided on the upper cover 100, and the transmitting device 300 is located on one side of the upper cover 100. The transmitting device 300 is a laser transmitter, and the laser transmitter emits in the direction of the solar film 900.

[0050] The receiving device 400 is a receiver 410 that receives the laser light emitted by the laser transmitter. A first mounting groove 110 is linearly formed on the upper cover 100 at a position corresponding to the receiver 410. The receiver 410 is movably mounted in the first mounting groove 110 so that the receiver 410 can move along the first mounting groove 110.

[0051] The laser emitter is arranged at a position corresponding to the first mounting groove 110;

[0052] On the lower cover 200, that is, on a side of the solar film 900 relative to the laser emitter and receiver 410, a reflecting device 500 and a reflecting mirror 600 are provided. The reflecting mirror 600 is installed corresponding to the position of the laser emitter, so that when the laser emitter emits laser light, the laser light passes through the solar film 900 and irradiates the reflecting mirror 600. In this application, the angle of the reflecting mirror 600 is 45 degrees, so that the reflecting mirror 600 reflects the laser light vertically. The reflecting device 500 is provided on the lower cover 200 corresponding to the receiving device 400, so that the laser light irradiates the reflecting device 500.

[0053] The reflecting device 500 includes a reflector 510, which is mainly a prism. The prism is tilted, and like the reflector 600, it is tilted at an angle of 45 degrees, so that the laser reflected by the reflector 510 will pass through the solar film 900 for the second time, and then be received by the receiver 410, completing the light transmittance inspection of the solar film 900.

[0054] In the above description, a second mounting groove 210 is provided on the lower cover 200 at a position corresponding to the reflector 510 , and the reflector 510 is movably mounted in the second mounting groove 210 , so that the reflector 510 moves along the second mounting groove 210 ;

[0055] Under the above structure, the prism on the reflector 510 has a fixed light transmittance, and the light transmittance effect of the solar film 900 can be judged by the size of the transmitted light. The judgment size is obtained by cooperating with a conventional detection device. The conventional detection device only measures once through the solar film 900. In this application, an additional measurement through the solar film 900 is added to increase the detection accuracy.

[0056] Among them, in order to further increase the detection accuracy, in this application, the reflector 510 slides in the second mounting groove 210 through an electric slider. Similarly, the receiver 410 slides in the first mounting groove 110 through a slider, and light transmittance detection is performed on different parts of the solar film 900 by sliding.

[0057] In the above description, the launching device 300 is disposed on the plane formed by the first installation groove 110 and the second installation groove 210 .

[0058] Second embodiment:

[0059] like Figure 7-8 As shown, in the present application, the receiving device 400 includes a plurality of receivers 410, a plurality of first mounting grooves 110 are linearly opened on the upper cover 100, and the plurality of first mounting grooves 110 are arranged in parallel on the upper cover 100, and the plurality of receivers 410 are respectively arranged in the first mounting grooves 110, so that a receiver 410 is arranged in each first mounting groove 110;

[0060] As in the first embodiment, the receiver 410 is slidably connected in the first mounting groove 110 via an electric slider, so that the receiver 410 moves to a designated position in the first mounting groove 110;

[0061] In the above description, there are seven first mounting slots 110 provided in the upper cover 100 , and corresponding receivers 410 are provided in each of the seven first mounting slots 110 ;

[0062] The reflecting device 500 includes a plurality of reflectors 510. The lower cover 200 is linearly provided with a plurality of second mounting grooves 210. The plurality of second mounting grooves 210 are arranged in parallel on the lower cover 200, and the plurality of second mounting grooves 210 are arranged corresponding to the positions of the first mounting grooves 110. The plurality of reflectors 510 are respectively arranged in the second mounting grooves 210, so that each second mounting groove 210 is provided with a reflector 510.

[0063] In the above structure, there are 7 corresponding second mounting slots 210, each of which is provided with a corresponding reflector 510, and the multiple reflectors 510 correspond to the multiple receivers 410 one by one;

[0064] In this application, there is only one transmitting device 300. Since there are seven receivers 410 and reflectors 510, it is necessary to split the light of the transmitting device 300 into seven optical paths. To solve this problem, an optical path splitter 800 is provided. The optical path splitter 800 can split the light of the transmitting device 300 into seven optical paths, specifically:

[0065] The optical path splitter 800 is provided with an inlet 810 and multiple outlets 820. The inlet 810 is provided corresponding to the emitting device 300, and the multiple outlets 820 are provided corresponding to the positions of the reflectors 510, so that the light from the outlets 820 is irradiated onto the corresponding reflectors 510 through the reflector 600.

[0066] It should be noted that the optical path splitter 800 mainly divides one optical path into seven smaller optical paths. The light in each of the seven optical paths is identical to the light emitted by the laser transmitter, so that there is no loss or wavelength splitting of the light, thus ensuring the stability and accuracy of the test.

[0067] In the present application, the path in the optical path splitter 800 is preferably selected as an optical fiber path to reduce the loss to a negligible level. Even if there is loss, it will not affect the detection effect of the solar film 900.

[0068] Since seven optical paths are provided in the second embodiment of the present application, in order to improve the detection efficiency, the reflection efficiency on each corresponding reflector 510 is different, such as:

[0069] The first reflection is 10 percent and the transmittance is 90 percent; the second reflection is 11.1 percent and the transmittance is 88.9 percent; the third reflection is 11.2 percent and the transmittance is 88.8 percent; the fourth reflection is 14.1 percent and the transmittance is 85.9 percent; and so on, for segmented reflection.

[0070] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
