[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] The preferred embodiments of the present invention will now be further described with reference to the accompanying drawings. Figures 1 to 7As shown, an automatic transmittance detection device includes a support assembly 100, which includes a support platform 110 made of a transparent medium. The top of the support platform 110 is used to place the product to be tested for transmittance. A first translation mechanism 200 is provided at the bottom of the support assembly 100, which drives the support assembly 100 to move linearly along a first direction. A detection assembly 300 is provided at the end of the first translation mechanism 200, which includes vertically opposed detection probes 310 for detecting transmittance. A second translation mechanism 400 is provided at the bottom of the detection assembly 300, which drives the detection assembly 300 to move linearly along a second direction. The first and second directions are not parallel. When the first translation mechanism 200 drives the support assembly 100 to move toward the detection assembly 300, the support platform 110 is located between the detection probes 310.

[0023] This application pertains to a light transmittance testing device, which is mainly used to test the light transmittance of products such as glass or screens. In the working state of this application, the product to be tested (such as glass or screen) is first placed on the support platform 110 on top of the support assembly 100. It should be noted that the support platform 110 is made of a transparent medium, and its material can be liquid or gas, which is not limited here. In addition, the support platform 110 can be a single layer or multiple layers.

[0024] When testing is required, the first translation mechanism 200 is activated to drive the support platform 110 to move towards the detection component 300 along a preset first direction (direction A in the figure). During the movement, the support platform 110 is inserted between the detection probes 310, so that the product to be tested is located between the detection probes 310. It should be noted that the detection probes 310 have a transmitting end and a receiving end. They emit specific electromagnetic waves to continue to detect the light transmittance of the product between them. The specific principle is existing technology and will not be elaborated here. When it is necessary to test different horizontal surfaces of the product, the second translation mechanism 400 is activated to drive the detection probes 310 along a preset second direction (direction B in the figure). Since the first direction and the second direction are not parallel, the second translation mechanism 400 can drive the detection probes 310 to move along different directions, so that different positions of the product to be tested can be detected.

[0025] Compared with the prior art, this application moves the support component 100 and the detection component 300 in different directions, and keeps the detection platform between the detection probes 310 during the movement, so that it can automatically cover the transmittance of any point of the product without blind spots. This can not only replace manual labor, but also effectively reduce product breakage and scratches.

[0026] Furthermore, based on the above embodiments, the first direction and the second direction are perpendicular to each other. This allows the support component 100 and the detection component 300 to move relative to each other along the X and Y axes, thereby enabling more efficient full-coverage inspection of the product. Additionally, it makes it easier to accurately position the support component 100 and the detection component 300 via computer, thus improving the accuracy of repeated product inspections through precise positioning and movement.

[0027] Furthermore, based on the above embodiments, such as Figure 2 As shown, the support assembly 100 further includes a first base 120, which is slidably connected to the first translation mechanism 200. First support frames 130 are provided on both sides of the first base 120, and the support platform 110 is fixed between the first support frames 130, thus suspending the support platform 110 above the first base 120. When the first translation mechanism 200 drives the support platform 110 to move towards the detection assembly 300, one of the detection probes 310 is located above the support platform 110, and the other detection probe 310 is located between the support platform 110 and the first base 120, thereby allowing the support platform 110 to be held between the detection probes 310.

[0028] Furthermore, based on the above embodiments, such as Figure 2 As shown, the first translation mechanism 200 includes parallel first guide rails 210 laid along the first direction. A first sliding seat 220 is mounted on the first guide rails 210, and the first sliding seat 220 can slide along the first guide rails 210. The first sliding seat 220 is fixed to the bottom of the first base 120. A first drive motor 230 is provided on one side of the first guide rails 210. When it is necessary to drive the support assembly 100 to move linearly along the first direction, the first drive motor 230 is activated to drive the first sliding seat 220 to slide along the first guide rails 210, thereby driving the support assembly 100 to slide along the first guide rails 210.

[0029] Furthermore, based on the above embodiments, such as Figure 3As shown, the detection assembly 300 includes a second base 320, which is slidably connected to the second translation mechanism 400. Two connecting rods 330 are arranged parallel to each other on the top of the second base 320, and the connecting rods 330 are arranged vertically opposite each other. The detection probe 310 is located at the end of the connecting rod 330 away from the second base 320, and the connecting rod 330 is parallel to the first direction. In this way, the detection probe 310 has sufficient length to extend into both sides of the product for detection through the connecting rod 330. Furthermore, since the connecting rod 330 is parallel to the first direction, it is easier to accurately position the detection probe 310.

[0030] Furthermore, based on the above embodiments, such as Figure 3 As shown, the second translation mechanism 400 includes parallel second guide rails 410 laid along the second direction. A second sliding seat 420 is mounted on the second guide rail 410, and the second sliding seat 420 can slide along the second guide rail 410. A second drive motor 430 is provided on the top of the second base 320, and limit sensors 440 are provided on both sides of the second guide rail 410. When it is necessary to drive the detection component 300 to move linearly along the second direction, the second drive motor 430 is activated to drive the second sliding seat 420 to slide along the second guide rail 410, thereby driving the detection component 300 to slide along the second guide rail 410. When it moves to both ends and contacts the limit sensors 440, a limit signal is triggered, causing the second drive motor 430 to stop working, thus preventing the second base 320 from detaching from the second guide rail 410.

[0031] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 4 As shown, a first electrode conducting device 500 is also provided on one side of the support assembly 100. The first electrode conducting device 500 is fixed to the support assembly 100 and moves synchronously with the support assembly 100. The first electrode conducting device 500 includes a first connecting plate 510, the end of which is located above the support platform 110. A lifting cylinder 520 is provided at the top of the end of the first connecting plate 510, and several conductive electrodes 530 are provided at the bottom of the lifting cylinder 520. The first electrode conducting device 500 is mainly used for products that require conductivity to be tested, such as electrically controlled dimming glass. When testing is required, the lifting cylinder 520 can be driven to lower the conductive electrodes 530 to contact the product under test, energizing the product. Then, the support assembly and the first electrode conducting device 500 can be driven to move synchronously to complete the test.

[0032] Based on the above embodiments, combined with Figure 5 and Figure 6 As shown, this application also provides a second embodiment, which differs from the first embodiment in that at least one second electrode conducting device 600 is provided on one side of the support component 100. The second embodiment is also intended to address products that require electrical conductivity for testing, but compared to the first embodiment, the second embodiment is mainly for testing irregularly shaped products. The product to be tested in the second embodiment has an extension 20 extending from the side of the body 10, and a support portion 30 is provided between the end of the extension 20 and the body 10. For this irregularly shaped product to be tested, the second electrode conducting device 600 includes a support groove 610, and at least one guide groove 620 is provided in different directions of the support groove 610. A power supply device 630 is provided at the end of the guide groove 620 away from the support groove 610. When it is necessary to power on the product to be tested of a different shape, the support part 30 is snapped into the support groove 610, which can support the middle section of the extension part 20. Then, the extension part 20 is snapped into the guide groove 620, so that the end of the extension part 20 faces the power supply device 630. Then, the power supply device 630 is driven to connect to the end of the extension part 20, so that the product to be tested is powered on to complete the test. It should be noted that the guide groove 620 can be arranged in different directions of the support groove 610 for extension parts 20 of different directions to accommodate different products of different shapes. No further limitation is made here.

[0033] Furthermore, based on the above embodiments, such as Figure 7 As shown, the energizing device 630 includes a third guide rail 631, a third sliding seat 632 mounted on the third guide rail 631, a second connecting plate 633 mounted on the top of the third sliding seat 632, a connecting sleeve 634 provided on one side of the second connecting plate 633 facing the extension 20, and a conductive terminal 635 provided on the other side, a baffle 636 provided on the third guide rail 631, and a spring 637 provided between the baffle 636 and the third sliding seat 632. When the energizing device 630 needs to connect to the end of the extension 20, it pushes the third sliding seat 632 toward the extension 20, causing its connecting sleeve 634 to embed around the extension 20, and then energizes the product under test through the conductive terminal 635. The spring 637 serves to buffer the connection between the connecting sleeve 634 and the extension 20.

[0034] The details of the exemplary embodiments described above are provided, and the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention.
