Description

Technical Field

[0001] The present invention relates to the technical field of glass color difference detection, and in particular to an online coated glass color difference detection method. Background Art

[0002] Coated glass is also called reflective glass. Coated glass is a glass surface coated with one or more layers of metal, alloy or metal compound film to change the optical properties of the glass to meet certain specific requirements. Coated glass can be divided into the following categories according to the different characteristics of the product: heat reflective glass, low-emissivity glass (Low-E), conductive film glass, etc.

[0003] Compared with small glass, coated glass is larger in size. Its common standard specifications include 1200mm×2000mm, 1500mm×2000mm, 1800mm×2100mm, etc. These sizes are suitable for the installation needs of most windows, doors and partitions; and common small sizes include 500mm×700mm, 600mm×900mm, etc., which are also relatively large in size.

[0004] In the prior art, coated glass detection generally uses a color difference detector for detection. For example, the patent with announcement number CN214951808U discloses an online LOW-E glass rapid color difference detection device, which uses a color difference detector for detection.

[0005] Once a defective product is found after the inspection is completed, the defective product can be rejected by a rejection mechanism, such as the online LOW-E glass color difference detection mechanism proposed in the patent with announcement number CN217894417U.

DETAILED DESCRIPTION

[0021] According to the following Figure 1-Figure 22 The invention describes an online coated glass chromatic aberration detection method provided by an embodiment of the invention.

[0022] See also Figure 1 The embodiment of the present invention provides an online coated glass color difference detection method, comprising the following steps: Step 1: The coated glass is transported to the position of the detection mechanism 3 by the first conveyor mechanism 2. After the coated glass reaches the bottom of the detection mechanism 3, the detection mechanism 3 moves and detects the color difference of the coated glass in a scanning manner; Step 2: Judge the result of color difference detection and obtain the test result as qualified or unqualified; Step 3: After the inspection, the coated glass enters the second conveyor mechanism 6 and is conveyed by the second conveyor mechanism 6; Step 4: If the color of the coated glass after the color difference test is unqualified, the coated glass is lifted off the second conveyor belt mechanism 6 and moved to a position away from the second conveyor belt mechanism 6. If the color of the coated glass after the color difference test is qualified, the second conveyor belt mechanism 6 continues to transport the qualified coated glass to the packaging position.

[0023] Therefore, the online coated glass color difference detection method provided by the embodiment of the present invention can detect the color difference of the coated glass in the entire area in a scanning manner, and is used for large coated glass. Moreover, since unqualified glass is removed in a lifting manner, it can better ensure stability during removal and avoid breakage of the coated glass compared to the suction cup lifting method in the prior art.

[0024] In the above method, a first bracket 1 , a first conveyor belt mechanism 2 , a detection mechanism 3 , a second conveyor belt mechanism 6 , a lifting mechanism 4 and a linear guide mechanism 7 are required.

[0025] like Figure 2 The first bracket 1 is located above the first conveyor belt mechanism 2, and the detection mechanism 3 is assembled on the first bracket 1. The detection mechanism 3 is used to detect the color difference of the coated glass. The second conveyor belt mechanism 6 is used as a place to remove and convey unqualified coated glass. The upper supporting mechanism 4 is used to lift the unqualified coated glass. The linear guide mechanism 7 is used to move the upper supporting mechanism 4 carrying the unqualified coated glass to a position away from the second conveyor belt mechanism 6.

[0026] Combination Figure 3 , Figure 5-Figure 10 As shown, the above-mentioned detection mechanism 3 includes at least a detection carrier plate 34, a tilting structure 32 and three detection heads 37. The detection head 37 is installed below the detection carrier plate 34. The detection carrier plate 34 is preferably in a rectangular shape, which is located above the first conveyor belt mechanism 2 and parallel to the conveying direction of the first conveyor belt mechanism 2. The tilting structure 32 is tilted relative to the first conveyor belt mechanism 2, and the tilting structure 32 is used to drive the detection carrier plate 34 to tilt and move, so that the detection head 37 can laterally scan the coated glass in a tilted posture. The transverse direction here refers to the direction perpendicular to the conveying direction of the first conveyor belt mechanism 2, so that larger coated glass can be detected in all directions.

[0027] Preferably, the oblique movement structure 32 includes an inclined screw rod 321, a first guide rod 322, a second motor 324 and an oblique movement block 325. Bearing seats 323 are provided at both ends of the inclined screw rod 321, and the inclined screw rod 321 is rotatably mounted on the bearing seats 323 through bearings. The oblique movement block 325 is threadedly connected to the inclined screw rod 321. When the inclined screw rod 321 rotates, the oblique movement block 325 can be displaced, and when it moves, it can drive the detection carrier plate 34 and the detection head 37 below to move horizontally, so that the detection head 37 can perform all-round detection. In addition, the first guide rod 322 is fixed between the two bearing seats 323 for guiding the oblique movement block 325. The second motor 324 is fixed on one of the bearing seats 323, and the second motor 324 is used to drive the inclined screw rod 321 to rotate.

[0028] It should be noted that the moving speed of the oblique moving block 325 here is equal to the conveying speed of the first conveyor belt mechanism 2 in the direction of the first conveyor belt mechanism 2, and the moving speed of the oblique moving block 325 in the direction perpendicular to the transmission direction of the first conveyor belt mechanism 2 is equal, thereby ensuring that the detection head 37 can detect the coated glass in an all-round manner in a following manner.

[0029] Specifically, refer to Fig. 9 As shown, Fig. 9 (a) shows that the first coated glass reaches the bottom of the detection head 37. At this time, the distance between the first coated glass and the second coated glass behind is h3. At this time, the rotation of the tilting screw 321 can drive the detection carrier 34 to move to the lower left corner. The component speed of the detection carrier 34 moving downward (this component speed should be adjusted by adjusting the rotation speed of the tilting screw 321) is equal to the speed of the coated glass moving downward below, and finally reaches Fig. 9 (b) The state shown in Fig. 9 (b) is the state shown, at this time relative to Fig. 9 In the state shown in (a), the displacement of the coated glass is h1, and the displacement of the tilting block 325 is h2, then h1=h2. Since the second coated glass needs to reach the bottom of the detection head 37 after the tilting block 325 returns, Fig. 9 (c) state, so h3=2h1.

[0030] Of course, in actual operation, the size of each batch of coated glass is different. In order to facilitate the adaptation to glass of different sizes, the tilting structure 32 is configured as a component with adjustable angle.

[0031] Specifically, the detection mechanism 3 also includes a track structure 31, and the track structure 31 is located on both sides of the first conveyor belt mechanism 2, and the track structure 31 is suspended under the first bracket 1. The track structure 31 is an arc-shaped structure, and the two ends of the oblique structure 32 are located in the relative track structures 31, so that the two ends of the oblique structure 32 can slide inside the track structure 31, so that the inclination angle of the oblique structure 32 can be adjusted to adapt to the size of the coated glass.

[0032] The track structure 31 includes a track body 311, in which a lifting slider 313 is slidably arranged, and the lower end of the lifting slider 313 extends downward and is fixedly connected to the bearing seat 323. By directly pushing the tilting screw rod 321, the two ends of the tilting screw rod 321 can slide in the track body 311, thereby adjusting its own tilt angle. Figure 6 In the state shown, the more the tilting screw 321 is rotated counterclockwise, the longer the length of the coated glass swept by the detection head 37 is. Fig. 9 (a) shows a relatively short length of the coated glass. When the coated glass is longer, the length that the detection carrier 34 needs to move downward is longer. Fig.10 As shown in (a), at this time, the length of the detection glass is relatively large, so it is necessary to adjust the inclination and rotation speed of the tilting screw 321 before the detection. Fig. 9 In the state shown in (a), the tilting screw rod 321 is rotated counterclockwise to form Fig.10 (a) shows the state where the tilting screw 321 rotates during the detection and gradually forms Fig.10 (b) shows the state, and then the detection head 37 is reset to detect the second coated glass.

[0033] In actual operation, in order to ensure that the detection carrier plate 34 below remains in a direction parallel to the conveying direction of the first conveyor belt mechanism 2 even after the oblique movement structure 32 adjusts its own angle, an adaptation shaft 33 is also provided, the lower end of the adaptation shaft 33 is fixed to the middle of the detection carrier plate 34, and the upper end of the adaptation shaft 33 is rotatably installed on the power output end of the oblique movement structure 32, the power output end mentioned here is the oblique movement block 325, so that the angle between the detection carrier plate 34 and the oblique movement structure 32 can be relatively changed; compensation rods 341 are provided at both ends of the detection carrier plate 34, and a horizontal slider 343 is slidably provided at the end of the compensation rod 341 away from the detection carrier plate 34, and a horizontal slider 343 is fixed at a position on the first bracket 1 opposite to the horizontal slider 343 and perpendicular to the conveying direction of the first conveyor belt mechanism 2, and the horizontal slider 343 is sleeved on the horizontal slider 36 and can slide on the horizontal slider 36.

[0034] Preferably, a compensation spring 342 is sleeved on the compensation rod 341 to buffer the vibration effect of the sliding of the compensation rod 341 on the detection head 37 .

[0035] Figure 8 In the state shown, as the tilting screw rod 321 rotates, the tilting block 325 gradually moves to the lower left, so that the detection carrier 34 moves to the lower left. However, due to the guidance of the horizontal slide bar 36, the detection carrier 34 can only be horizontal; when the angle of the tilting screw rod 321 is manually adjusted ( Fig.10 In the state shown in the figure), under the guidance of the horizontal slider 343 and the horizontal slide bar 36, the detection carrier 34 can still only be in a state parallel to the first conveyor belt mechanism 2, ensuring the accurate position of its detection head 37.

[0036] It should be noted that the curvature of the track body 311 should be Fig. 9 In the state shown, the position of the adaptation axis 33 is the arc of the circle center, Fig. 9 The state shown is the initial state of the detection head 37. In this state, the tilting screw rod 321 can be pushed so that the two ends of the tilting screw rod 321 can move along the track body 311 to adjust the inclination of the tilting screw rod 321. Once the inclination adjustment is completed and the tilting screw rod 321 rotates, the positions of the oblique moving block 325 and the detection carrier plate 34 below on the tilting screw rod 321 change, so that the position of the adaptation shaft 33 also changes. The two ends of the tilting screw rod 321 have a tendency to slide in the track body 311, but due to the change in the position of the adaptation shaft 33 (that is, the adaptation shaft 33 is no longer located in the center area of ​​the track body 311), the track body 311 limits the position change of the two ends of the tilting screw rod 321, so that the tilting screw rod 321 can self-lock after adjusting the angle.

[0037] like Figure 6 In order to further ensure that the tilting screw rod 321 is locked in position after the angle adjustment is completed, a long groove 314 is opened on the periphery of the track body 311, and a clamping bolt 315 is provided, and a threaded hole adapted to the clamping bolt 315 is provided on the lifting slider 313, so that the self-locking of the tilting screw rod 321 after the angle adjustment is further achieved by tightening the clamping bolt 315.

[0038] like Figure 4 In order to improve the detection accuracy of the detection head 37, the first conveyor belt mechanism 2 here includes a narrow belt 21, a first motor 26 and a support plate 24. The narrow belt 21 is arranged in multiple groups, and a part of space should be reserved between two adjacent groups of narrow belts 21. The two ends of the narrow belt 21 are driven by the pulley 22, and the two ends of the pulley 22 are rotatably installed on the first support 23. The first motor 26 is used to drive one of the pulleys 22 to rotate. The support plate 24 is located in the middle of the interlayer of the narrow belt 21, and a light source board 25 is installed on the upper surface of the support plate 24. The light source board 25 is used to provide a light source when detecting coated glass, thereby improving the brightness of the detection head 37 during detection and improving the accuracy of the detection result.

[0039] like Figure 2 , Figure 11-13 As shown, the second conveyor belt mechanism 6 mentioned above is arranged at the discharge end of the first conveyor belt mechanism 2, and it can receive the coated glass from the first conveyor belt mechanism 2. The second conveyor belt mechanism 6 includes an intermediate conveyor belt 65, a lifting roller 62 and a lifting drive structure 64; the intermediate conveyor belt 65 plays a major conveying role, the middle part of the coated glass is located on the intermediate conveyor belt 65, the lifting rollers 62 are arranged on both sides of the intermediate conveyor belt 65 close to the first conveyor belt mechanism 2, and both sides of the coated glass are located on the lifting rollers 62. When the intermediate conveyor belt 65 and the lifting rollers 62 rotate synchronously, the coated glass can be conveyed.

[0040] In essence, a connecting roller 61 is provided at one end of the second conveyor belt mechanism 6 close to the first conveyor belt mechanism 2 . The connecting roller 61 is located on both sides of the intermediate conveyor belt 65 and is coaxial with one end of the intermediate conveyor belt 65 close to the first conveyor belt mechanism 2 .

[0041] like Fig.14 and Fig.15 The lifting roller 62 here includes a first main cylinder body 621 away from the middle conveyor belt 65 and a hemispherical head 623 close to the middle conveyor belt 65. There is an installation gap between the first main cylinder body 621 and the hemispherical head 623, and a first cylinder shaft 622 is fixed in the middle of the first main cylinder body 621 and the hemispherical head 623. When the first cylinder shaft 622 rotates, the first main cylinder body 621 and the hemispherical head 623 can rotate, thereby achieving the purpose of conveying coated glass.

[0042] In addition, the lifting drive structure 64 is arranged in the installation gap, and the lifting drive structure 64 is used to drive the lifting roller 62 to flip, so that the hemispherical head 623 can lift the coated glass upward, leaving both sides of the lower surface of the coated glass vacant, thereby providing lifting space for the subsequent upper supporting mechanism 4 to lift the coated glass.

[0043] Reference Fig.13 and Fig.14 As shown, the aforementioned lifting drive structure 64 includes an intermediate shaft seat 645, a side frame 646 and a bidirectional cylinder 641, wherein the intermediate shaft seat 645 is connected to the first cylinder shaft 622 through a bearing, and is used to support the lifting roller 62, so that the lifting roller 62 is in a lifting state or a horizontal state, and the intermediate shaft seat 645 is located in the installation gap, and two adjacent intermediate shaft seats 645 are fixedly connected by a flip shaft 644, and then when the flip shaft 644 rotates, it can drive the entire lifting roller 62 to be in a lifting state through the intermediate shaft seat 645 ( Fig.16 The lifting roller 62 is in a horizontal state. In this state, the lifting roller 62 is used to transport the coated glass. Fig.17The lifting roller 62 is in the state of lifting the coated glass. In this state, the upper support mechanism 4 works to lift the entire coated glass upward and away from the second conveyor belt mechanism 6. Preferably, the flip shaft 644 is mounted on the side frame 646 via a bearing; Specifically, in order to realize the rotation of the flip shaft 644 , a rack plate 642 is installed on the piston rod of the bidirectional cylinder 641 , and a flip gear 643 that can mesh with the rack plate 642 is fixed on the flip shaft 644 .

[0044] In addition, if Fig.13 In order to achieve the purpose of conveying the qualified coated glass to the required position, the second conveyor belt mechanism 6 here also includes side rollers 67. The side rollers 67 are located on both sides of the part of the intermediate conveyor belt 65 away from the first conveyor belt mechanism 2. A driving shaft 68 for driving the intermediate conveyor belt 65 to rotate is arranged at both ends of the intermediate conveyor belt 65. In order to realize the self-rotation feeding of the side rollers 67, a main transmission structure 69 is also arranged. The main transmission structure 69 includes a belt transmission member 693. The side rollers 67 and the driving shaft 68 are connected by the belt transmission member 693. There is a power transmission roller 66 between the side rollers 67 and the lifting roller 62. One end of the power transmission roller 66 and one end of the side roller 67 are both installed with a first main gear 691. A first intermediate gear 692 is meshed between two adjacent first main gears 691, so that the side rollers 67, the power transmission roller 66 and the driving shaft 68 rotate synchronously.

[0045] like Fig.14In order to realize that the lifting roller 62 can rotate together with the power transmission roller 66, a feeding transmission structure 63 is also provided. The feeding transmission structure 63 can connect the power transmission roller 66 and the first cylinder shaft 622, so that the power transmission roller 66 drives the first cylinder shaft 622 to rotate synchronously, and then the lifting roller 62 can rotate on its own to transport coated glass. In order to realize that the power transmission roller 66 drives the lifting roller 62 to rotate through the feeding transmission structure 63 and the feeding transmission structure 63, the power transmission roller 66 here includes a second main cylinder body 661 away from the middle conveyor belt 65 and an auxiliary cylinder body 662 close to the middle conveyor belt 65. A second cylinder shaft 663 is provided in the middle of the second main cylinder body 661 and the auxiliary cylinder body 662. There is also an installation gap between the second main cylinder body 661 and the auxiliary cylinder body 662; the feeding transmission structure 63 includes a second bevel gear 634, a first bevel gear 633 and a base 610, the second bevel gear 634 is fixed to the part of the second cylinder shaft 663 located in the installation gap and the part of the first cylinder shaft 622 located in the installation gap, the first bevel gear 633 is meshed with the second bevel gear 634 below, and a coaxial second main gear 631 is provided below the first bevel gear 633, a second intermediate gear 632 is meshed between two adjacent second main gears 631, the base 610 is located below the second conveyor belt mechanism 6, and the shaft of the second intermediate gear 632 and the shaft of the second main gear 631 are both rotatably mounted on the base 610.

[0046] In this embodiment, when the power transmission roller 66 rotates, it can drive the second bevel gear 634 on itself to rotate, and then drive a coaxial second main gear 631 to rotate through the first bevel gear 633 below itself, so that the remaining second main gears 631 and second intermediate gears 632 are rotated due to the action of the second intermediate gear 632, and then the first bevel gears 633 are rotated, and the first drum shaft 622 can be rotated due to the action of the second bevel gear 634, thereby achieving the purpose of self-rotation and feeding of the lifting roller 62.

[0047] It should be noted that when the lifting roller 62 gradually turns over, the second bevel gear 634 thereon gradually disengages from the first bevel gear 633, so that during the lifting stage, the lifting roller 62 does not rotate and does not feed materials.

[0048] In addition, the above step four requires the use of an upper supporting mechanism 4 and a linear guide mechanism 7. The upper supporting mechanism 4 is located above the second conveyor belt mechanism 6, and the upper supporting mechanism 4 can lift the coated glass in the vacant areas on both sides of the lower surface of the coated glass. The linear guide mechanism 7 can drive the upper supporting mechanism 4 to move in a direction perpendicular to the transmission direction of the second conveyor belt mechanism 6, so as to drive the upper supporting mechanism 4 away from the second conveyor belt mechanism 6, thereby realizing the removal of unqualified coated glass.

[0049] Combination Fig.11 , Fig.18 , Fig.19 As shown in the figure, the upper supporting mechanism 4 includes a U-shaped frame 41, a bidirectional screw rod 49, a third motor 44, a fourth guide rod 46 and a reeling and unreeling structure 47.

[0050] The U-shaped frame 41 is located above the second conveyor belt mechanism 6, and side panels 42 are provided at the lower sides of the U-shaped frame 41, and a support plate 43 is provided on the side of the side panel 42 close to the center of the U-shaped frame 41. A bidirectional screw rod 49 is rotatably installed on the upper part of the U-shaped frame 41, and the side panel 42 is threadedly connected with the bidirectional screw rod 49, so that the bidirectional screw rod 49 can make the two side panels 42 close to the coated glass or away from the coated glass when rotating. A third motor 44 is installed on the U-shaped frame 41 to drive the bidirectional screw rod 49 to rotate. A fourth guide rod 46 is fixed in the U-shaped frame 41 to guide the side panel 42. A reeling and unreeling structure 47 is installed on the linear guide rail mechanism 7, and the reeling and unreeling structure 47 is used to drive the U-shaped frame 41 to rise or fall.

[0051] Preferably, a third guide rod 411 is further installed on the U-shaped frame 41 , which cooperates with the linear guide rail mechanism 7 to reduce the shaking of the U-shaped frame 41 when the retracting and unreeling structure 47 lifts or lowers the U-shaped frame 41 .

[0052] In this embodiment, when the third motor 44 is working, the bidirectional screw 49 rotates to make the two side plates 42 approach the coated glass or move away from the coated glass. When the two side plates 42 are close to each other, the support plate 43 can enter the empty area below the two sides of the coated glass (such as Fig.17 ), at this time, the retractable and unreeling structure 47 can lift the U-shaped frame 41 upwards, so that the support plate 43 can lift the coated glass upwards. Compared with the suction cup transfer of coated glass in the prior art, this method is more stable.

[0053] Preferably, the above-mentioned reeling and unreeling structure 47 includes a reeling motor 471 , a reeling wheel 472 installed at the power output end of the reeling motor 471 , and a steel rope 473 with one end wound around the reeling wheel 472 and the other end fixed to the U-shaped frame 41 .

[0054] In addition, it should be noted that the linear guide mechanism 7 is similar to the structure of a bridge crane in the prior art, which includes a bridge frame 73, a trolley 71 mounted above the bridge frame 73, and a straight track 72 running on the trolley 71. The winding motor 471 is installed on the straight track 72. The straight track 72 and the trolley 71 here can be coordinated by a screw drive, a gear drive or a region drive method that can realize the movement of the trolley 71 on the straight track 72.

[0055] The third guide rod 411 mentioned above passes through the trolley 71 , and the third guide rod 411 can slide up and down along the trolley 71 .

[0056] Reference Fig.18 , Fig. 20 , Fig.21 and Fig. 22 As shown, since the unqualified coated glass needs to be relocated to a desired position after being transported by the linear guide mechanism 7, such as a trolley for transferring the unqualified coated glass, in order to ensure that the damage to the coated glass is minimized when the unqualified coated glass is released to the trolley, the two ends of the support plate 43 are rotatably mounted in the side plate 42, and an angle adjustment structure 48 is provided on one side of the support plate 43 located in the side plate 42. The angle adjustment structure 48 includes a gear portion 484, and the gear portion 484 is fixed to the support plate. 43, and a moving rod 482 is provided on one side of the gear portion 484, and a first rack portion 483 meshing with the gear portion 484 is provided on the moving rod 482. A force rod 45 is also fixed in the U-shaped frame 41, and the force rod 45 includes a second horizontal section 453, and upwardly inclined sections 452 are provided at both ends of the second horizontal section 453, and a first horizontal section 451 is provided at the other end of the inclined section 452. A slip ring 481 is fixed to the upper end of the moving rod 482, and the slip ring 481 can slide on the force rod 45.

[0057] In this implementation, the crawling phase: Reference Fig.21 As shown, when the unqualified coated glass reaches the lifting roller 62, the lifting roller 62 lifts it. In the initial state, the state of the support plate 43 is as follows: Fig.21 As shown in (a), as the bidirectional screw 49 works, the two side plates 42 approach each other, the slip ring 481 passes through the inclined section 452, and moves downward to push the moving rod 482 to move downward, so that the moving rod 482 can drive the gear part 484 to rotate through the first rack part 483, so that the support plate 43 gradually tends to be horizontal, forming Fig.21 In the state shown in (b), when the slip ring 481 reaches the position of the second horizontal section 453, the support plate 43 completely reaches the horizontal state. At this time, the retractable and reeling structure 47 lifts the U-shaped frame 41, and the linear guide mechanism 7 transfers the coated glass.

[0058] Reference Fig. 22 Release stage: When the linear guide mechanism 7 moves the coated glass to the desired position, the retractable and reeling structure 47 lowers the U-shaped frame 41. Fig. 22 In the state shown in (a), the two side plates 42 move away from each other through the reverse rotation of the bidirectional screw rod 49. At this time, the slip ring 481 moves upward through the inclined section 452, and then the first rack part 483 drives the gear part 484 to rotate in the reverse direction, forming Fig. 22 In the state shown in (b), as the two side panels 42 continue to move away from each other, the coated glass is placed on the desired trolley.

[0059] When in use (at work): ①Glass detection The coated glass is transported on the first conveyor mechanism 2. When the glass reaches the bottom of the detection mechanism 3 (when multiple detection heads 37 are evenly distributed above the coated glass along the length direction of the coated glass), the oblique movement structure 32 works to drive the oblique movement block 325 to move obliquely along the inclined screw rod 321. At this time, the horizontal slider 343 slides on the horizontal slider 36, and the compensation rod 341 slides on the horizontal slider 343. When sliding, the detection head 37 under the detection carrier plate 34 can scan the entire coated glass in all directions (the moving speed of the oblique movement block 325 here is equal to the component speed of the first conveyor mechanism 2 in the direction of the first conveyor mechanism 2, thereby ensuring that the detection head 37 can detect the coated glass in all directions in a following manner). After the detection, the judgment system determines whether it is qualified. If it is unqualified, this unqualified coated glass should be discarded after entering the position of the second conveyor mechanism 6.

[0060] ②Removal of unqualified coated glass When the entire coated glass block reaches the position of the second conveyor mechanism 6 and is located below the upper supporting mechanism 4, the controller controls the bidirectional cylinder 641 to shorten, so that the rack plate 642 drives the second bevel gear 634 to rotate, and the flip shaft 644 drives the intermediate shaft seat 645 to rotate, so that the lifting roller 62 can lift the coated glass through the hemispherical head 623, so that the lower sides of the coated glass are vacated. At this time, the third motor 44 works, and the bidirectional screw 49 rotates, so that the two side plates 42 are close to the coated glass supporting plate 43 and can enter the vacant area below the two sides of the coated glass (such as Fig.17 ), at this time, the retractable and unreeling structure 47 can lift the U-shaped frame 41 upward, so that the support plate 43 can lift the coated glass upward. After the linear guide mechanism 7 transfers the coated glass, the coated glass needs to be released. Fig. 22 In the state shown in (a), the two side plates 42 move away from each other through the reverse rotation of the bidirectional screw rod 49. At this time, the slip ring 481 moves upward through the inclined section 452, and then the first rack part 483 drives the gear part 484 to rotate in the reverse direction, forming Fig. 22 In the state shown in (b), as the two side panels 42 continue to move away from each other, the coated glass is placed at the desired position.
