[0002] With the modernization of society, light pollution has become a new source of environmental pollution, following exhaust gas, wastewater, solid waste, and noise pollution. Examples include glare from rearview mirrors while driving, increased cancer rates due to excessive light exposure, and disruption of plant physiological rhythms caused by nighttime light. Therefore, research on electrochromic films has gradually become a hot topic in recent years. Electrochromic films are now gradually entering various aspects of our lives, such as home windows, electrochromic glasses, automotive glass, and rearview mirrors. After the electrochromic film is manufactured, it typically undergoes appearance and transmittance testing to determine whether its surface and transmittance performance meets standards.

[0003] However, the current electrochromic film appearance testing and transmittance testing devices are separate, which requires the product to be transferred between the two devices during testing, which is not conducive to production. Utility Model Content

[0031] Electrochromic films are gradually being incorporated into various aspects of our lives, such as home windows, electrochromic glasses, automotive glass, and rearview mirrors. After the electrochromic film is manufactured, it typically undergoes appearance and transmittance testing to determine if its color-changing and transmittance performance meets standards. Currently, appearance and transmittance testing for electrochromic films are separate processes, requiring the product to be transferred between two workstations during testing, which is inconvenient for production.

[0032] Based on this, in order to solve the above problems, this application designs a testing device, in which a first detection component and a second detection component are arranged at intervals on the frame, which can simultaneously realize the appearance inspection and transmittance test of the device under test; and by using the moving component and the positioning component, the device under test can be automatically transported between the first detection position and the second detection position, realizing an automated operation process and effectively saving labor costs.

[0033] refer to Figures 1 to 6One embodiment of this application provides a testing device, including a frame 10 and a first detection component 100, a second detection component 200, a moving component 300, and a positioning component 400 for fixing a device under test 1 disposed on the frame 10; the first detection component 100 and the second detection component 200 are arranged at intervals along a first direction X, the light emitted by the first detection component 100 illuminates a first detection position, and the light emitted by the second detection component 200 illuminates a second detection position; the moving component is movable along the first direction, so that the positioning component 400 is transported between the first detection position and the second detection position.

[0034] Specifically, the positioning component 400 supports the device under test 1 to prevent it from shifting during testing and to ensure testing accuracy. The moving component 300 can drive the positioning component 400 to reciprocate between the first detection position and the second detection position.

[0035] In one optional embodiment, the device under test 1 is an electrochromic film, and the testing device is used to perform appearance and transmittance tests on the electrochromic film to determine whether the appearance and transmittance performance of the electrochromic film meet the standards. Of course, in other embodiments, the sample provided in this embodiment can also be other products that require appearance and transmittance testing.

[0036] When the device under test 1 is in the first detection position, the first detection component 100 is used to emit light to illuminate the device under test 1, so that the operator can make a preliminary appearance confirmation of the device under test 1 and observe whether there are visible appearance defects, such as point defects (white spots, light distortion points, etc.) and line defects (such as scratches, spots, etc.), to ensure that the device under test 1 meets the basic conditions for transmittance testing.

[0037] When the device under test (DUT) 1 is in the second detection position, the second detection component 200 is used to emit light to illuminate the DUT 1 in order to detect the transmittance of the DUT 1. For example, the second detection component 200 may include any light transmittance testing instrument, which can emit light and pass through the DUT 1 and receive the passed light. It is understood that when the light emitted by the light transmittance testing instrument passes through the DUT 1, it will be partially absorbed and reflected by the DUT 1, resulting in a decrease in the intensity of the light received again. By comparing the light intensity before and after the detection, the transmittance of the DUT 1 can be obtained.

[0038] For example, see reference Figure 2 The first direction X is the X direction shown in the figure. In this embodiment, the first direction X is the vertical direction, that is, the device under test 1 is moved between the first detection position and the second detection position by controlling the rise and fall of the device under test 1.

[0039] The testing device of this application can perform appearance inspection on the device under test 1 through the first detection component 100 to determine whether there are defects in the appearance of the device under test 1; it can test the transmittance of the device under test 1 through the second detection component 200, thereby simultaneously realizing appearance inspection and transmittance testing of the device under test 1; and it can automatically transport the device under test 1 between the first detection position and the second detection position by using the moving component 300 and the positioning component 400, without the need for manual handling, realizing an automated operation process, effectively saving labor costs and testing time.

[0040] refer to Figures 2 to 6 In some embodiments, the moving component 300 includes a support frame 310 and a conveying module 320 for driving the support frame 310 to move along a first direction X; the positioning component 400 is disposed on the support frame 310.

[0041] Specifically, the support frame 310 is a frame structure, which can be, but is not limited to, rectangular, trapezoidal, polygonal, etc. The device under test 1 is placed in the support frame 310 so that the light from the first detection component 100 and the second detection component 200 can shine directly onto the device under test 1.

[0042] The positioning component 400 on the support frame 310 fixes the device under test 1, so that the device under test 1 remains structurally stable within the support frame 310 and is prevented from shifting during the test.

[0043] The conveying module 320 is used to drive the support frame 310 to move along the first direction X, thereby enabling the support frame 310 to carry the device under test 1 to move along the first direction X.

[0044] For example, the conveying module 320 can be a motor lifting structure, a worm gear lifting structure, a conveyor belt lifting structure, etc., to provide lifting driving force for the support frame 310.

[0045] refer to Figure 3 and Figure 4 In some embodiments, the positioning component 400 includes at least one connecting rod 410 slidably disposed on the support frame 310 and a positioning clamp 420 disposed on the connecting rod 410, the positioning clamp 420 being used to clamp the device under test 1; the connecting rod 410 is movable and adjustable relative to the support frame 310 along a second direction Y, the second direction Y intersecting the first direction X.

[0046] Specifically, the device under test 1 is placed inside the support frame 310, and the two opposite surfaces of the device under test 1 are clamped by the positioning clamps 420 to stably support the device under test 1.

[0047] In some embodiments, the positioning clamp 420 is provided with a flexible element for contacting the surface of the device under test 1. Direct contact between the flexible element and the device under test 1 avoids scratching the surface of the device under test 1, thus improving test reliability.

[0048] For example, the length of the device under test 1 along the second direction Y in this application ranges from 0 to 800 mm; the width of the device under test 1 along the first direction X ranges from 0 to 800 mm. Understandably, the dimensions of the support frame 310 are configured to be larger than the dimensions of the device under test 1 to ensure that the device under test 1 can be placed inside the support frame 310.

[0049] The device under test 1 is placed inside the support frame 310. The first direction X is the height direction of the device under test 1, and the second direction Y intersects with the first direction X. Then, as the connecting rod 410 moves along the second direction Y, the position of the connecting rod 410 will change along the second direction Y.

[0050] In one specific embodiment of this example, the second direction Y is the Y direction shown in the figure. The second direction Y is perpendicular to the first direction X, that is, the second direction Y is parallel to the length direction of the device under test 1. The device under test 1 is placed inside the support frame 310. The connecting rod 410 is adjusted to move along the second direction Y to approach the device under test 1, so that the positioning clamp 420 can stably clamp the device under test 1. Then, by adjusting the connecting rod 410 to move along the second direction Y, it can be adapted to devices under test 1 of different lengths.

[0051] refer to Figure 3 In some embodiments, the support frame 310 is a rectangular frame structure, including two crossbeams spaced apart along a first direction X. The two ends of the connecting rod 410 are slidably connected to the crossbeams, meaning the connecting rod 410 can slide along the second direction Y using the crossbeams as tracks. For example, each end of the connecting rod 410 can be provided with a sliding block, and the sliding block has rollers that roll along the crossbeams. The movement of the connecting rod 410 is adjusted by the rollers rolling along the crossbeams. Understandably, the damping between the rollers and the crossbeams can be configured such that the connecting rod 410 can only move relative to the crossbeams under the action of an external force.

[0052] refer to Figure 3 and Figure 4 In some embodiments, the connecting rod 410 extends along the first direction X, and the positioning clamp 420 is slidably disposed on the connecting rod 410 so as to be movable and adjustable along the first direction X.

[0053] Understandably, when the device under test 1 is located inside the support frame 310, the width direction of the device under test 1 is parallel to the first direction X, and the connecting rod 410 extends along the first direction X. Then, depending on the width of the device under test 1, the positioning clamp 420 can slide along the connecting rod 410 to adjust to a suitable clamping position, resulting in better adaptability.

[0054] In one example, refer to Figure 3 A connecting rod 410 can be set on the support frame 310, and the positioning clamp 420 on the single connecting rod 410 can clamp and support the device under test 1.

[0055] In another example, two connecting rods 410 can be provided on the support frame 310. By adjusting the two connecting rods 410 to be located on both sides of the device under test 1, the positioning clip 420 on a single connecting rod 410 clamps and supports one side of the device under test 1, so as to provide stable support for the device under test 1.

[0056] Understandably, one positioning clamp 420 can be provided on a single connecting rod 410; or, multiple positioning clamps 420 can be provided at intervals on a single connecting rod 410, with the multiple positioning clamps 420 used to simultaneously clamp the device under test 1.

[0057] Preferably, the support frame 310 is provided with two spaced-apart connecting rods 410, and each connecting rod 410 is provided with two spaced-apart positioning clips 420.

[0058] refer to Figure 6 and Figure 7 In some embodiments, the moving component 300 further includes a support body 330 and a guide rod 340; the support body 330 includes a support beam 331 and side support plates 332 respectively disposed on both sides of the support beam 331, and the side end of the support frame 310 is connected to the side support plate 332 on the corresponding side; the guide rod 340 is disposed on the frame 10 along the first direction X and passes through the support beam 331, and the conveying module 320 is used to drive the support beam 331 to move along the guide rod 340.

[0059] Specifically, two side support plates 332 are provided on the support beam 331 at intervals along the second direction Y; the support frame 310 is connected between the two side support plates 332, and the structural connection is stable.

[0060] In one specific embodiment, reference Figure 7The support beam 331 is provided with guide rods 340 on both sides of the second direction Y. The guide rods 340 can guide the support beam 331 to move, so that the support beam 331 can move smoothly. The conveying module 320 drives the support beam 331 to move along the first direction X to drive the support frame 310 to move. During the lifting process, the two sides of the support frame 310 can maintain good parallelism through the guide rods 340.

[0061] One or more guide rods 340 can be provided on one side of the supporting beam 331 in the second direction Y to guide the movement of the supporting beam 331. Preferably, the supporting beam 331 is provided with two spaced-apart guide rods 340 on one side of the supporting beam 331 in the second direction Y.

[0062] refer to Figures 6 to 7 In some embodiments, the conveying module 320 includes a worm gear drive assembly 321 and a drive assembly 322; the worm gear drive assembly 321 includes a worm 3211 passing through the support beam 331 and a turbine 3212 rotatably mounted on the worm 3211, the turbine 3212 being connected to the support beam 331; the drive assembly 322 is used to drive the worm 3211 to rotate so as to drive the turbine 3212 to move along the worm 3211, so as to move the support beam 331 along the first direction X.

[0063] Understandably, the support beam 331 is driven to move along the first direction X by a worm gear transmission, and the worm 3211 is driven to rotate by the drive assembly 322. The worm gear 3212 drives the support beam 331 to move up and down. The worm gear structure has high load capacity and high support strength. It also has smooth transmission, low impact and vibration, and very low noise during operation, which effectively improves transmission stability.

[0064] refer to Figure 7 In some embodiments, worm gear transmission assemblies 321 are respectively provided on both sides of the support beam 331; the drive assembly 322 includes a motor 3221, a first transmission belt assembly 3222 and a second transmission belt assembly 3223; the first transmission belt assembly 3222 includes a first transmission belt 2 that is driven to the output end of the motor 3221 and driven wheels 3 on both sides of the first transmission belt 2, the first transmission belt 2 is used to drive the driven wheels 3 on both sides to rotate synchronously; the second transmission belt assembly 3223 is respectively provided on both sides of the support beam 331, the second transmission belt assembly 3223 includes a drive wheel 4 for driving the worm gear 3211 to rotate and a second transmission belt 5 that is driven between the drive wheel 4 and the driven wheel 3.

[0065] Specifically, worm gear transmission assemblies 321 are respectively provided on both sides of the support beam 331, which can stably drive the support beam 331 to move. The worm gear transmission assembly 321 is located on the side and will not interfere with the second detection assembly 200. The structure layout is reasonable and compact.

[0066] The specific driving process of the drive assembly 322 is as follows: the motor 3221 starts running to drive the first transmission belt 2 to move. The first transmission belt 2 drives the driven wheels 3 on both sides to rotate synchronously. The driven wheels 3 rotate and drive the second transmission belt 5 on the corresponding side to move, thereby driving the drive wheel 4 to rotate. The rotation of the drive wheel 4 causes the worm gear transmission assembly 321 on the corresponding side to control the support beam 331 to move along the first direction X.

[0067] Understandably, the driven wheels 3 on both sides of the first transmission belt assembly 3223 rotate synchronously and drive the corresponding worm gear transmission assembly 321 to perform transmission operations through the second transmission belt assembly 3223; thereby enabling the worm gear transmission assemblies 321 on both sides to maintain synchronous lifting and lowering motion, which can ensure the smooth operation and positioning accuracy of the support beam 331.

[0068] For example, in order to improve the transmission stability of the first transmission belt assembly 3222, multiple wheel sets can be set to drive the first transmission belt 2 so that the driven wheels 3 on both sides rotate synchronously. This application will not elaborate on this in detail.

[0069] In some embodiments, the first detection component 100 includes a light source for emitting light to inspect the appearance of the device under test. Specifically, the light source can be a first light source 110, which provides uniformly distributed illumination to avoid local overexposure or darkness when observing the device under test, thereby improving the accuracy of the detection results. The brightness and illumination angle of the light source can be adjusted according to the inspection requirements. With the above settings, the first detection component 100 can maintain good observation conditions in different environments, thereby ensuring the reliability of the inspection process.

[0070] refer to Figures 5 to 9 In some embodiments, the second detection component 200 has a receiving cavity 210 in which the device under test is located to correspond to a second detection position. The second detection component 200 includes a detection unit 220 for emitting and receiving light to detect the transmittance of the device under test 1.

[0071] Specifically, after the appearance inspection of the device under test 1 is completed at the first detection position, the moving component 300 controls the support frame 310 to move along the first direction X into the receiving cavity 210, in preparation for transmittance detection.

[0072] refer to Figure 8 In some embodiments, the second detection component 200 includes two detection carriers 230 arranged opposite to each other, with the two detection carriers 230 surrounding a receiving cavity 210; and a single detection carrier 230 is slidably disposed on the frame 10 so that the two detection carriers 230 can perform opening and closing movements.

[0073] The two detection carriers 230 can open and close to adjust the size of the receiving cavity 210. The two detection carriers 230 open to ensure that the device under test 1 can be moved into the receiving cavity 210. After the device under test 1 is in the receiving cavity 210, the two detection carriers 230 close together so that the light emitter 221 and the light receiver 222 can approach the device under test 1 with reference to the position of the detection carriers 230, thereby achieving accurate transmittance detection.

[0074] Continue to refer to Figure 9 In some embodiments, the detection unit 220 includes a light emitter 221 disposed on one of the detection carriers 230 and a light receiver 222 disposed on the other detection carrier 230. The position of the light emitter 221 corresponds to the position of the light receiver 222, and the light receiver 222 is capable of receiving the light emitted by the light emitter 221.

[0075] Specifically, when the device under test (DUT) 1 is in the second detection position, DUT 1 is located between two detection carriers 230. At this time, the light emitted by the light emitter 221 can pass through one of the detection carriers 230 to reach DUT 1, and then pass through the other detection carrier 230 to reach the light receiver 222 and be received by the light receiver 222. When the light emitted by the light emitter 221 passes through DUT 1, it will be partially absorbed and reflected by DUT 1, resulting in a decrease in the intensity of the light received by the light receiver 222. By comparing the intensity of the light received by the light receiver 222 before and after detection, the transmittance of DUT 1 can be obtained.

[0076] refer to Figure 10 In some embodiments, the bottom end of the detection carrier 230 is provided with a slide 6, and a guide rail 7 is correspondingly formed on the frame 10, with the slide 6 slidably engaged on the guide rail 7; the frame 10 is also provided with an actuation component 8 for driving the detection carrier 230 to slide.

[0077] For example, the actuation component 8 may employ, but is not limited to, electric push rods, belt pulley drives, worm gear drives, etc., as long as it can drive the two detection carriers 230 to perform stable opening and closing movements.

[0078] In some embodiments, the detection carrier 230 is provided with a plurality of mounting holes 231 arranged in an array, the mounting holes 231 being used to mount a light emitter 221 or a light receiver 222.

[0079] Understandably, in order to perform transmittance detection at multiple locations on the device under test 1, the detection carrier 230 in this embodiment is provided with multiple mounting holes 231 arranged in an array. A light emitter 221 is used to pass through and be installed in one of the mounting holes 231 of the detection carrier 230, and a light receiver 222 is used to pass through and be installed in another mounting hole 231 of the detection carrier 230. Then, for different sizes of the device under test 1, suitable mounting holes 231 are selected on the detection carrier 230 to set the light emitter 221 and the light receiver 222. For example, the array arrangement is a matrix array.

[0080] For example, during the transmittance test, based on the device under test 1, nine mounting holes 231 are selected on one of the testing carriers 230 and light emitters 221 are set up respectively. On another testing carrier 230, nine mounting holes 231 are selected at the corresponding positions and light receivers 222 are set up respectively. This results in transmittance data for the device under test 1 at nine positions, enabling the testing of data at different positions. This allows for a better understanding of the transmittance changes at each position of the product and reduces random errors caused by single-tube testing.

[0081] refer to Figure 9 In some embodiments, the light emitter 221 is elastically stretchable.

[0082] Specifically, the light emitter 221 has a cylindrical structure. During testing, the emitting end of the light emitter 221 needs to be close to and in contact with the surface of the device under test 1. The light emitter 221 can be elastically stretched and extended, so that the light emitter 221 can make close contact with the device under test 1 without damaging the device under test, thus improving the protection of the product.

[0083] For example, the light emitter 221 is provided with a spring 9 inside, which enables the light emitter 221 to be retractable and adjustable.

[0084] refer to Figure 9 In some embodiments, the optical receiver 222 is elastically extendable.

[0085] Specifically, the optical receiver 222 has a cylindrical structure. During testing, the transmitting end of the optical receiver 222 needs to be close to and in contact with the surface of the device under test 1. The optical receiver 222 can be elastically stretched and extended, so that the optical receiver 222 can make close contact with the device under test 1 without damaging the device under test, thus improving the protection of the product.

[0086] For example, the optical receiver 222 is provided with a spring 9 inside, which enables the optical receiver 222 to be retractable and adjustable.

[0087] refer to Figure 1 and Figure 2In some embodiments, the frame 10 includes a base 101 and a platform 102 spaced apart along a first direction X. A first detection component 100 is disposed on the end face of the platform 102 opposite to the base 101. A second detection component 200 is disposed on the base 101. An avoidance window 1021 is provided on the platform 102. The positioning component 400 moves from the first detection position to the second detection position through the avoidance window 1021.

[0088] In this embodiment, the first direction X is the vertical direction, and the base 101 and the platform 102 are arranged at intervals in the vertical direction; the first detection component 100 is disposed on the platform 102, and the second detection component 200 is disposed on the base 101; the structural layout is reasonable and compact, effectively improving the space utilization rate.

[0089] An obstacle avoidance window 1021 is provided on the base 102. The obstacle avoidance window 1021 allows the support body 330 and the support frame 310 to pass through, thereby enabling the device under test 1 to move stably between the first detection position and the second detection position.

[0090] refer to Figure 1 , Figure 2 , Figures 11 to 13 The testing device also includes a third detection component 500 disposed on the base 102. The light source part includes a first light source 110, which has a front side for emitting light and a back side opposite to the front side. The third detection component 500 is disposed facing the back side of the first light source. The third detection component includes a storage frame 510 for placing the device under test 1 and a second light source 520 disposed directly opposite to the storage frame 510. The second light source 520 is used to emit light to illuminate the device under test 1 placed in the storage frame 510.

[0091] Both the first light source 110 and the second light source 520 are backlight panels with adjustable illuminance ranges from 0 to 10,000 Lux.

[0092] Specifically, the third detection component 500 is set on the base 102 and faces the back of the first light source 110. After the device under test 1 completes the transmittance detection, under the action of the moving component 300, the device under test 1 moves back to the first detection position along the first direction X. Then, the operator removes the device under test 1 from the support frame 310 and places it in the storage frame 510, which can stably support the device under test 1. The second light source 520 can emit light to illuminate the device under test 1 located in the storage frame 510, and then the operator can perform a comprehensive inspection of the appearance of the device under test 1.

[0093] refer to Figures 11 to 13In some embodiments, the frame 10 is provided with support rods 11 on both sides of the third detection component 500, and a rotation adjustment seat 530 is provided on the side of the support rod 11 near the third detection component 500, and the rotation adjustment seat 530 can be rotated and adjusted relative to the support rod 11; the storage frame 510 and the second light source 520 are both connected to the rotation adjustment seat 530.

[0094] Specifically, the storage frame 510 and the second light source 520 are positioned opposite each other, and the rotating adjustment seat 530 is connected to the side end of the storage frame 510 and the side end of the second light source 520. Thus, the storage frame 510 and the second light source 520 form an adjustable whole through the rotating adjustment seat 530. The rotating adjustment seat 530 is rotatably connected to the support rod 11, so that the whole formed by the storage frame 510 and the second light source 520 can be rotated and adjusted relative to the support rod 11.

[0095] Understandably, after the device under test 1 is placed in the storage frame 510, the second light source 520 illuminates the device under test 1 directly, which makes it convenient for the operator to observe the appearance of the device under test 1. In addition, the operator can also adjust the storage frame 510 and the second light source 520 relative to the support rod 11 by rotating the adjustment seat 530 to adjust different observation angles, so as to make the appearance inspection more comprehensive and careful, and effectively observe whether there are visible appearance defects in the device under test 1, such as point defects, linear defects, etc., to ensure that the appearance of the device under test 1 is free from problems.

[0096] refer to Figures 11 to 13 In some embodiments, the storage frame 510 is provided with a positioning component for fixing the device under test 1. The positioning component includes at least one connecting rod slidably disposed on the storage frame 510 and a positioning clamp disposed on the connecting rod. The positioning clamp is used to clamp the device under test 1.

[0097] It should be noted that the positioning components on the storage frame 510 in this embodiment are configured in the same way as those in the first detection component 100. Specifically, the storage frame 510 is a rectangular frame structure, and it is provided with two spaced-apart connecting rods and a positioning clip on each connecting rod. The device under test 1 is placed inside the storage frame 510. The storage frame 510 includes two crossbeams spaced apart along the first direction X. The two ends of the connecting rods are slidably connected to the crossbeams, meaning the connecting rods can slide along the crossbeams as tracks. By adjusting the movement of the connecting rods, it can accommodate devices under test 1 of different sizes. The positioning clips clamp the two opposite surfaces of the device under test 1 to stably support it.

[0098] refer to Figure 1 and Figure 2In some embodiments, the testing apparatus further includes a power supply component 600 disposed on the base 102, the power supply component 600 being disposed between the first detection component 100 and the third detection component 500.

[0099] Understandably, the power supply assembly 600 is used to supply power to the electrical equipment of the device to ensure stable operation of the equipment. Furthermore, the power supply assembly 600 is positioned between the first detection assembly 100 and the third detection assembly 500 to improve space utilization.

[0100] Understandably, the testing apparatus of this application also includes a control module, which is electrically connected to each component. The control module can control the operation of each component according to a pre-input control program, such as controlling the switching of the first light source 110 and the second light source 520, controlling the movement component 300 to drive the device under test 1 to move, and controlling the opening and closing movements of the two detection carriers 230 in the second detection component 200. For example, the control component may also include multiple control buttons, allowing the operator to control each component to operate independently.
