It can use various systems such as magnetic induction transmission and electric transmission to control the blinds inside the hollow glass, and adjust the lifting and flapping angle by 180 degrees to achieve natural lighting and complete shading functions. When the product is processed, a magnet is placed inside the glass. After the glass processing is completed and installed, another magnet is placed at the corresponding magnet position. The lifting and lowering of the blinds are controlled by moving the external magnet up and down. After the product is produced, it needs to be tested for light transmittance to detect the light transmittance of the internal blinds under various adjustment states.

[0043] See also Figure 1-11 The present invention provides a technical solution: an automatic light transmittance testing device for hollow louver glass, comprising a translation slide 7, a testing platform 1, a testing chamber 5 and a light shield 2,

[0044] The detection platform 1 is movably arranged on the upper side of the translation slide 7, the detection chamber 5 is fixed to one side of the upper end of the translation slide 7, the light shield 2 is liftably arranged on the inner side of the detection chamber 5, and the light shield 2 is provided with a light source 201 inside;

[0045] The inspection platform 1 includes a center platform 101, which is used to carry the window body 6. The four sides of the center platform 101 are provided with a positioning plate 102 and a positioning plate 2 103. The positioning plate 102 and the positioning plate 2 103 move horizontally relative to each other to clamp and position the window body 6.

[0046] A concave card 202 is provided on one side of the inner side of the light shield 2, and the concave card 202 corresponds to the magnetic control slider on the upper side of the window body 6. A linear drive assembly is provided on one side of the concave card 202 for driving the concave card 202 to drive the magnetic control slider to move;

[0047] The size of the light shield 2 corresponds to the size of the outer frame of the window body 6. The light shield 2 is pressed down on the outer frame of the window body 6 to shield external light, and the concave clamp 202 is clamped on the outside of the magnetically controlled slider and moves to control the dimming of the Venetian blinds. The light source body 201 performs a light transmittance test on the window body 6, and a light intensity sensor is arranged on the inner side of the center platform 101.

[0048] The testing platform 1 is set up to carry the window body 6 to be tested. Specifically, the staff first places the window body 6 on the upper side of the center platform 101, and positioning plates 1 102 and 103 are set on the four sides of the center platform 101, and in the initial state, there is a distance difference between the center platform 101 and the window body 6, so that it is convenient for the staff to place the window body 6, and then the positioning plates 1 102 and 103 are relatively moved to clamp the window body 6 on the middle side and limit it in the center, so that it is convenient for the testing platform 1 to move along the translation slide 7, driving the window body 6 to move into the testing room 5, and then a light shield 2 is set in the testing room 5, and the light shield 2 can be driven down by a linear drive mechanism, and because the light shield The size of the light shield 2 corresponds to the outer frame size of the window body 6. Therefore, the light shield 2 covers the frame of the window body 6 in the limit position, thereby shielding the external light from entering the light shield 2, greatly reducing the influence of external factors. Then, the light source 201 set in the light shield 2 is used to test the light transmittance of the window body 6 under the light shield 2, and a corresponding light intensity sensor is set on the inner side of the central station 101 to collect values, so that the light emitted by the light source 201 passes through the hollow venetian blinds and is sensed by the light intensity sensor, so as to judge whether the light transmittance, that is, the shading rate of the current test window body 6 is qualified when the venetian blinds are fully closed, thereby ensuring the light shielding performance of the customer in daily use;

[0049] Preferably, since the hollow venetian blinds can be controlled by an external magnetically controlled slider to adjust various shading states, in order to test whether the shading rate of the hollow venetian blinds is stable under various adjustment states, a concave clamp 202 is provided. The concave clamp 202 moves synchronously with the light shield 2, so that when the light shield 2 is stuck on the outer frame of the window body 6, the concave clamp 202 is correspondingly stuck on the outside of the magnetically controlled slider. Then, the concave clamp 202 can be driven to move by the internally arranged linear drive component, thereby driving the magnetically controlled slider to move relatively, and the venetian blinds in the fully closed state are slowly opened, so that the light transmittance can be tested under various adjustment states. The test is relatively accurate and comprehensive, and has a high degree of automation, thereby improving the detection efficiency.

[0050] The testing platform 1 also includes a support frame 104, and the positioning plate 102 and the positioning plate 2 103 are both slidably matched with the support frame 104. A plurality of spring contraction rods are arranged on the inner side of the support frame 104, and the spring contraction rods are connected to the positioning plate 2 103. The two ends of the positioning plate 102 are fixedly connected with extension plates 105, and a guide telescopic rod 106 is arranged between the extension plate 105 and the support frame 104. A limiting triangular groove is provided on the inner side of the extension plate 105, and the limiting triangular groove is aligned with the positioning plate 102. The two ends of the positioning plate 2 103 are set to be chamfered, and the two ends of the positioning plate 2 103 are adapted to the limiting triangular groove. A pair of positioning plates 102 are driven by a linear drive part to move relative to each other, and the limiting triangular groove limits the positioning plate 2 103 and drives it to move relative to each other.

[0051] In the initial state, the spring retracts the rod to keep the second positioning plate 103 away from the center platform 101, making it convenient for the staff to place the window body 6;

[0052] When it is necessary to drive the positioning plate 102 to move, it is driven by a linear drive unit, such as a cylinder, a hydraulic cylinder or a lead screw mechanism, to drive a pair of positioning plates 102 to move relative to each other to clamp the window body 6. At the same time, when the positioning plate 102 moves, it drives the extension plate 105 to move, so that the limiting triangular grooves on both sides move relative to the positioning plate 103, thereby limiting the positioning plate 103, so that the chamfers at both ends move along the limiting triangular grooves, so that the positioning plate 103 can move toward the window body 6. When the positioning plate 102 completely clamps the window body 6, the limiting triangular groove also completely limits the positioning plate 103 from clamping the window body 6, so that the window body 6 can be aligned and limited, and the synchronous movement of the positioning plate 103 can be achieved only by moving the positioning plate 102, with a high degree of automation and cost saving.

[0053] The linear drive part includes a concave frame 107, the lower end of the concave frame 107 is slidably matched with the support frame 104, a plurality of spring telescopic rods 110 are arranged on one side of the concave frame 107, the spring telescopic rods 110 are connected to the support frame 104, the inner ends of the concave frame 107 are arranged with round chamfers, a sliding groove 112 is provided on the inner side of the concave frame 107, a pair of hinge columns 113 are slidably matched on the inner side of the sliding groove 112, a flip plate 108 is fixedly connected to one side of the hinge column 113, a rotating rod 109 is arranged at the center of the flip plate 108, the lower end of the rotating rod 109 is rotatably connected to the support frame 104, the other end of the flip plate 108 is hingedly connected to a hinge seat 114, the hinge seat 114 is slidably matched with the extension plate 105, when the concave frame 107 moves away from the positioning plate 102, the flip plate 108 is driven to push the extension plate 105 to move.

[0054] Preferably, when the positioning plate 102 needs to be driven, the concave frame 107 is moved away from the positioning plate 102. Since the rotating rod 109 is rotatably connected to the support frame 104, the concave frame 107 drives the flip plates 108 on both sides to flip around the rotating rod 109 as the axis, so that the flip plate 108 pushes the extension plate 105 to move, which can push the positioning plate 102 to clamp the window body 6, and simultaneously drive the positioning plate 2 103 to clamp, and set the sliding groove 112 and the hinge column 113 to slide with each other, and the hinge seat 114 slides relative to the extension plate 105, so as to facilitate the relative movement of the structure when the flip plate 108 flips;

[0055] A spring telescopic rod 110 is provided so that the pair of flip plates 108 remain parallel in the initial state and the positioning plate 102 is away from the center platform 101, so that the subsequent flip plate 108 pushes the positioning plate 102 to move.

[0056] A plurality of spring telescopic rods 115 are provided at the lower end of the center platform 101, and the spring telescopic rods 115 are connected to the support frame 104. Adaptation grooves are provided at the lower ends of both ends of the center platform 101, and a fixing rod 116 is fixedly connected in the adaptation groove. A hinge plate 117 is rotatably connected to the outer side of the fixing rod 116. A trapezoidal groove is provided at the lower end of the positioning plate 102, and the hinge plate 117 passes through the trapezoidal groove and is rotatably connected to the concave frame 107. The hinge plate 117 is in an inclined state in the initial state.

[0057] Preferably, a plurality of spring telescopic rods 115 are provided at the lower end of the center platform 101, so that the center platform 101 is in an ascending state in the initial state, so that the hinge plates 117 on both sides remain in an inclined state and the pair of flip plates 108 remain parallel. Then, when the center platform 101 drives the window body 6 to move to the lower side of the light shield 2, the light shield 2 moves and is pressed against the upper side of the window body 6 (at this time, the light shield 2 and the window body 6 are not completely aligned), and pushes it, so that the center platform 101 is synchronously lowered. Since the hinge plates 117 on both sides of the center platform 101 are in an inclined state (such as Figure 4 As shown in the figure), when the hinge plate 117 is subjected to the pressure of the upper center platform 101, it extends outward, thereby pushing the concave frame 107 to move away from the window body 6, and driving the positioning plate 102 to move in the opposite direction until the window body 6 is clamped and limited, so that the window body 6 is aligned and completely aligned with the light shield 2. In other words, the positioning plate can be driven only by the descent of the light shield 2, and the detection can be started immediately. The process connection is smooth, the work efficiency is improved, and no additional linear drive components are required for driving, which saves costs.

[0058] And because the outer frame of the window body 6 is equal to the size of the light-shielding cover 2, and the center platform 101 and the window body 6 are both pressed down a certain distance, the positioning plate 1 102 and the positioning plate 2 103 clamp the window body 6 while also clamping it on the outside of the light-shielding cover 2. In other words, the positioning plate covers the gap where the window body 6 and the light-shielding cover 2 meet, thereby further preventing external light from entering the interior through the gap, thereby affecting the detection result. In other words, while the positioning plate aligns the window body 6, it also further closes the gap where the window body 6 and the light-shielding cover 2 meet, which is highly practical.

[0059] A plurality of guiding telescopic columns are arranged at the upper end of the light shield 2, which are connected to the detection chamber 5. A motor component 501 is fixedly connected to the upper end of the detection chamber 5. A threaded rod 502 is driven at the lower end of the motor component 501. A threaded sleeve 503 is threadedly connected to the lower end of the threaded rod 502. The threaded sleeve 503 drives the light shield 2 to rise and fall.

[0060] Specifically, when the light shield 2 needs to be driven to rise or fall, the motor 501 drives the threaded rod 502 to rotate, and under the guidance of a plurality of guide telescopic columns, the threaded sleeve 503 drives the light shield 2 to rise or fall.

[0061] A partition 203 is fixedly connected to the middle side of the light shield 2, and the light source body 201 is arranged at the lower end of the partition 203. A guide plate 204 is fixedly connected to one side of the partition 203, and one end of the guide plate 204 is connected to the light shield 2. A sliding groove is provided on the middle side of the guide plate 204. A T-shaped plate 205 is fixedly connected to the upper end of the concave clamping member 202, and the T-shaped plate 205 moves along the sliding groove. The upper end of the T-shaped plate 205 is rotatably connected to a ring 206, and one end of the ring 206 is fixedly connected to a moving rod 207. The linear drive assembly includes a turntable 3, which is rotatably connected to the upper end of the partition 203. A sliding groove 301 is provided on one side of the turntable 3. The moving rod 207 extends into the sliding groove 301 and slides with it. A torsion spring is provided on the inner side of the turntable 3.

[0062] When it is necessary to adjust the position state of the venetian blind during the test, a T-shaped plate 205 is provided to move along the guide plate 204, thereby driving the concave clamping member 202 to move linearly, thereby driving the magnetic control slider to move. Specifically, the turntable 3 rotates, thereby driving the moving rod 207 to rotate. One end of the moving rod 207 extends into the sliding groove 301, thereby being restricted by the turntable 3 and rotating with it, while the other end is provided with a collar 206 rotatably connected to the T-shaped plate 205. When the turntable 3 rotates, the moving rod 207 is driven to rotate, and the moving rod 207 drives the T-shaped plate 205 to move along the guide plate 204. While the moving rod 207 rotates, it is retracted into the sliding groove 301 until the concave clamping member 202 moves to the middle end of the guide plate 204, and the moving rod 207 is perpendicular to the guide plate 204. Then the moving rod 207 extends out of the sliding groove 301 again until the concave clamping member 202 is completely moved, and the magnetic control slider completely opens the venetian blind, thereby completing the testing of its various states.

[0063] Preferably, a torsion spring is provided inside the turntable 3, so as to facilitate timely resetting after the detection is completed, that is, after the turntable 3 rotates, so as to facilitate the movement of the concave clamping member 202 next time.

[0064] The upper end of the light shield 2 is rotatably connected to the rotating plate 302, the threaded sleeve 503 penetrates the rotating plate 302 and is rotatably connected thereto, the lower end of the threaded sleeve 503 is fixedly connected to the driving disk 303, the outer side of the driving disk 303 is fixedly connected to a plurality of driving blocks 304, the lower end of the light shield 2 is fixedly connected to a plurality of fixing blocks 305, the driving blocks 304 and the fixing blocks 305 are both annularly distributed and mutually engaged, the upper end of the driving disk 303 is fixedly connected to a plurality of guide rods 306, the guide rods 306 penetrate the rotating plate 302 and are slidably matched therewith, the upper end of the guide rods 306 is fixedly connected to a baffle, and a spring member is provided between the baffle and the rotating plate 302;

[0065] A plurality of limiting posts 307 are fixedly connected to the upper end of the turntable 3 . After the driving block 304 is separated from the fixing block 305 , it engages with the limiting posts 307 and drives the turntable 3 to rotate.

[0066] Specifically, a rotating plate 302 is provided at the upper end of the light shield 2, and the rotating plate 302 can rotate relative to the light shield 2, and a driving disk 303 is fixedly connected to the lower end of the threaded sleeve 503, and a plurality of driving blocks 304 are provided on the outer side of the driving disk 303, and the driving blocks 304 and a plurality of fixed blocks 305 are mutually engaged, and the fixed blocks 305 restrict the driving blocks 304, that is, restrict the rotation of the driving disk 303, so that the driving disk 303 can only move up and down, and cannot rotate;

[0067] When the threaded rod 502 rotates, the driving disk 303 cannot rotate, and under the action of a plurality of spring members, the guide rod 306 always limits the upper end surface of the driving disk 303 from contacting the light shield 2, that is, the height of the driving disk 303 and the threaded sleeve 503 remains stationary. At this time, the threaded rod 502 rotates, and since the threaded sleeve 503 remains stationary, the threaded rod 502 drives the entire light shield 2 to descend and contact with the window body 6, thereby aligning the position of the window body 6. At this time, the light shield 2 cannot continue to descend. At this time, when the threaded rod 502 continues to rotate, the plurality of driving blocks 304 and the fixed blocks 305 slide against each other for guidance. The threaded sleeve 503 and the driving disk 303 descend relative to the light shield 2, and the spring members are compressed until the driving block 304 and the fixed block 305 are separated from each other. Similarly, a plurality of limiting posts 307 are provided on the turntable 3. The limiting posts 307 and the plurality of driving blocks 304 Correspondingly, after the driving block 304 is separated from the fixed block 305, it is engaged with the limiting column 307. At this time, when the threaded rod 502 rotates, due to the lack of restriction of the fixed block 305, the threaded rod 502 directly drives the threaded sleeve 503 to rotate, and the threaded sleeve 503 drives the driving disk 303, the guide rod 306 and the rotating plate 302 to rotate, so that the driving block 304 of the driving disk 303 is engaged with the limiting column 307, and the turntable 3 is driven to rotate, and the venetian blind can be adjusted. That is to say, after the threaded rod 502 drives the light shield 2 to descend, the threaded rod 502 continues to rotate to directly drive the threaded sleeve 503 to descend, so that the driving disk 303 loses the restriction of the fixed block 305 and drives the turntable 3 to rotate, thereby driving the concave clamping member 202 to move. The whole process can be achieved by using only a single motor component 501, which is highly practical and has a high degree of automation, thereby improving work efficiency.

[0068] A plurality of square grooves are provided on the outer side of the rotating plate 302, and spring telescopic rods three are arranged in the square grooves. Trapezoidal wedge blocks 4 are arranged at the outer ends of the spring telescopic rods three. A plurality of snap-in grooves 401 are provided in a ring shape on the inner side of the light shield 2, and the snap-in grooves 401 are snap-connected with the trapezoidal wedge blocks 4 in one direction.

[0069] Specifically, since the trapezoidal wedge block 4 and the plurality of engaging grooves 401 are engaged with each other, when the driving disk 303 drives the rotating disk 3 to rotate, the threaded rod 502 is in positive rotation, that is, when the driving disk 303 drives the rotating plate 302 to rotate forwardly relative to the light shield 2, the inclined surface of the trapezoidal wedge block 4 contacts the plurality of engaging grooves 401, so that the trapezoidal wedge block 4 is retracted into the square groove, which will not affect the positive rotation of the rotating plate 302. When the detection is completed and the light shield 2 needs to be reset, the threaded rod 502 is reversed, and the trapezoidal wedge block 4 is stuck in the engaging groove 401, so that the rotating plate 302 cannot be reversed, that is, the driving disk 303 cannot be reversed. Therefore, when the threaded rod 502 is reversed, the threaded sleeve 503 is driven to move upward and reset, and the driving block 304 is re-engaged with the fixed block 305, which is convenient for the next detection work.
