There is a belt support assembly under each belt to prevent the belt from "collapse", improve the movement straightness of the transmitted transparent flat plate, minimize the error caused by the movement of the transparent flat plate during the line scanning process, and ultimately ensure the straightness of the edge or straight line element of the transparent flat plate in the line scanning image.

[0003] The solution in the above patent document has the following defects:

[0004] A first support plate and a second support plate are provided, and both ends of the first step shaft assembly, the second step shaft assembly, the third step shaft assembly and the fourth step shaft assembly are respectively mounted on the first support plate and the second support plate. The above parts require high processing accuracy, are difficult to assemble, installation errors are difficult to guarantee, and maintenance is difficult, especially the replacement of wearing parts such as belts is difficult. Summary of the invention

[0005] The main purpose of the present invention is to provide a conveying mechanism for plate materials, which has low requirements on the processing accuracy of the rotating shaft and the supporting seat, is easy to install, has a small installation error, is very convenient to replace the first belt, and has a uniform and stable conveying speed.

[0006] To achieve the above-mentioned purpose, the present invention proposes a conveying mechanism for plate materials, including a driving device, a positioning device and at least two supporting seats, wherein a rotating shaft is provided on the supporting seat, and each rotating shaft is arranged side by side. The first end of each rotating shaft is rotatably mounted on the corresponding supporting seat, and the first end of each rotating shaft is respectively connected to the driving device for transmission, and at least two groups of first belts are connected to the second ends of each rotating shaft for transmission, and the upstream of each group of first belts is connected to the positioning device.

[0007] As a further improvement, the number of the support seats is at least three, and two rotating shafts are rotatably provided on a support seat located in the middle, one of the rotating shafts is connected to at least two groups of first belts with the rotating shaft on its adjacent support seat, and two groups of second belts are connected between the other rotating shaft and the rotating shaft on its adjacent support seat, the upstream of the second belt is connected to the downstream of the first belt, and a detection station is provided between the first belt and the second belt. In the present invention, a support seat provided with two rotating shafts can be defined as a double seat, and a support seat provided with only one rotating shaft can be defined as a single seat. An detection station can be provided between the second belt and the first belt, such as a glass detection station. Because there is a gap between the first belt and the second belt, and the gap is formed by the gap between the two rotating shafts on the double seat, the glass in transit can be detected without obstruction by utilizing the gap, and the defects of the glass can be accurately detected. Theoretically, a double seat can be replaced by two parallel single seats, but using two parallel single seats instead of a double seat may result in excessive gaps between the rotating shafts on the parallel single seats, as well as some other situations in the actual production process. Therefore, a double seat is more appropriate.

[0008] As a further improvement, a conveying mechanism for plate materials further comprises a fixing frame, wherein the fixing frame is fixedly arranged;

[0009] The first belt and the second belt are also provided with rollers, which are fixed on a fixed frame and are tangent to the inner side of the first belt or the inner side of the second belt. The rollers support the first belt and the second belt to prevent the first belt or the second belt from sagging due to excessive gravity when the first belt and the second belt are conveying plate materials.

[0010] As a further improvement, both the first belt and the second belt are round belts. When the round belts are used to convey the plate materials, the round belts and the plate materials are tangent to each other. Therefore, there is line contact between the round belts and the plate materials, which facilitates the positioning and conveying of the plate materials. The position of the plate materials is not easily deviated significantly during the conveying process.

[0011] Further improved, the support seat comprises a seat body, a bearing is embedded in the seat body, a step is provided between the first end of the rotating shaft and the middle part of the rotating shaft, the diameter of the first end of the rotating shaft is smaller than the inner diameter of the bearing, the diameter of the middle part of the rotating shaft is larger than the inner diameter of the bearing, the first end of the rotating shaft passes through the bearing and is connected to a fixing ring, and the rotating shaft is locked on the seat body through the fixing ring;

[0012] The second end of the rotating shaft is provided with a belt installation groove, and each rotating shaft is connected to the first belt or the second belt through the belt installation groove. The rotating shaft can be clamped in the bearing of the seat body through the fixed ring and the step formed between the first end of the rotating shaft and the middle part of the rotating shaft, so that the rotating shaft will not shake along its axial direction. The fixed ring can be a nut, and correspondingly, the first end of the rotating shaft can be provided with an external thread. The nut is locked on the first end of the rotating shaft through a locking sleeve, so that the rotating shaft can be locked on the seat body.

[0013] Further improved, a conveying mechanism for plate materials also includes a bottom plate, and the support seat is arranged on the bottom plate;

[0014] The positioning device includes a first adjustment plate, a second adjustment plate and two mounting plates, the mounting plates are vertically arranged on the bottom plate, the two mounting plates are parallel to each other, the same end of the two mounting plates is connected to the upstream of the first belt, and a screw rod and a slide rod are connected between the two mounting plates; the first adjustment plate and the second adjustment plate are parallel to each other, a left-handed nut is embedded in the first adjustment plate, and a right-handed nut is embedded in the second adjustment plate, the screw rod is inserted through the left-handed nut on the first adjustment plate, and the screw rod is also inserted through the right-handed nut on the second adjustment plate, the screw rod is provided with a first handle, and the first adjustment plate and the second adjustment plate are respectively slidably clamped on the slide rod. The screw rod can be rotated by the first handle, and the left-handed nut and the right-handed nut can be moved closer to or away from each other on the screw rod by rotating the screw rod, so that the first adjustment plate and the second adjustment plate can be moved closer to or away from each other, and the first adjustment plate and the second adjustment plate slide on the screw rod and the slide rod, and preferably, the number of slide rods can be set to two. Therefore, the spacing between the first adjustment plate and the second adjustment plate can be adjusted by adjusting the screw rod. The left-handed nut and the right-handed nut of the present invention can be fixed on the first adjustment plate or the second adjustment plate by a fixing block. The left-handed nut and the right-handed nut have substantially the same appearance, and the only difference between them is the different internal threads.

[0015] Before the plate material is transferred to the first belt, the plate material is placed on the slide rod and the screw rod, and the plate material can be clamped by adjusting the distance between the first adjustment plate and the second adjustment plate, thereby achieving the positioning of the plate material. After the plate material is positioned, the plate material can be transferred to the first belt.

[0016] As a further improvement, the mounting plate is further provided with a fixing seat, the screw rod passes through the fixing seat, and a fixing pin is provided on the fixing seat, and the fixing pin is movably set against the screw rod for fixing the screw rod. After the spacing between the first adjustment plate and the second adjustment plate is adjusted, the fixing pin can be used to hold the screw rod against the screw rod to prevent the screw rod from rotating, so that the position between the first adjustment plate and the second adjustment plate will not change. Preferably, a second handle can be provided on the fixing pin.

[0017] Further improved, the first adjustment plate and the second adjustment plate are respectively provided with a plurality of rollers, the wheel surface of the rollers is opposite to the first adjustment plate or the second adjustment plate, the rollers on the first adjustment plate are evenly distributed in a straight line along the surface of the first adjustment plate, the rollers on the second adjustment plate are evenly distributed in a straight line along the surface of the second adjustment plate, and the rollers on the first adjustment plate and the rollers on the second adjustment plate are respectively opposite. When the plate material is placed on the screw rod and the slide rod, the two sides of the plate material are respectively in contact with the rollers on the first adjustment plate and the rollers on the second adjustment plate, and the rollers have a guiding effect on the plate material and also facilitate the plate material to slide between the first adjustment plate and the second adjustment plate.

[0018] In a further improvement, the driving device includes a driving member and a transmission shaft, the driving member and the transmission shaft are connected in transmission, and the transmission shaft is connected in transmission with one end of each rotating shaft. The driving member is a motor, the driving member can be arranged at the bottom end of the bottom plate, the transmission shaft and the driving member are connected in transmission by a belt, and the transmission shaft and the first end of the rotating shaft can be connected in transmission by a gear mechanism or a belt mechanism.

[0019] As a further improvement, at least one of the rotating shafts is provided with a speed detection device, which is a speed sensor or an encoder for detecting the rotation speed of the rotating shaft. Since each rotating shaft is driven by a driving device and each rotating shaft rotates synchronously, generally speaking, only one rotating shaft needs to be provided with a speed detection device.

[0020] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0021] The present invention drives the first end of each rotating shaft to rotate through a driving device, and each rotating shaft drives the first belt to rotate, and each group of first belts can convey plate materials, such as glass, etc. Before the plate materials enter the first belts, they can also be positioned by a positioning device, which can ensure that the position of the plate materials will not deviate greatly during the conveying process, and facilitate the conveying and detection of the plate materials.

[0022] The first end of each rotating shaft of the present invention is respectively rotatably mounted on the corresponding support seat, thereby forming a cantilever structure. During installation, in order to ensure the consistency of each rotating shaft, it is only necessary to ensure the position of the support seat of each rotating shaft. If the rotating shaft is fixed by two support seats, it is necessary to ensure the position relationship of the two support seats fixing the same rotating shaft, and the position relationship of the support seats between different rotating shafts; and the two support seats of the same rotating shaft will also produce stuck, abnormal noise and other phenomena due to excessive coaxiality deviation, such as the scheme shown in the patent document with application number CN201710430059, so the processing accuracy and installation requirements for the support seat and the rotating shaft will be much higher. Compared with the patent document with application number CN201710430059, which discloses a high-precision conveying device for transparent flat plate appearance inspection, the present invention has a much lower installation requirement for the support seat and the rotating shaft, so the processing accuracy of the support seat and the rotating shaft, and the degree of coordination of each support seat and each rotating shaft during installation will also be much lower; at the same time, each support seat can be installed independently, with little mutual influence, and the replacement and installation of the first belt are very convenient.

[0034] like Figures 1 to 5 As shown, a conveying mechanism for plate materials includes a driving device 3, a positioning device 1 and at least two support seats 2, a rotating shaft 21 is rotatably provided on the support seat 2, and each rotating shaft 21 is arranged side by side. The first end 211 of each rotating shaft 21 is respectively connected to the driving device 3 by transmission, and at least two groups of first belts 22 are connected to the second end 212 of each rotating shaft 21 by transmission, and the upstream of each group of first belts 22 is connected to the positioning device 1.

[0035] In this embodiment, the first end 211 of each rotating shaft 21 is driven to rotate by the driving device 3, and each rotating shaft 21 drives the first belt 22 to rotate, and each group of first belts 22 can convey plate materials 23, such as glass, etc. Before the plate materials 23 enter the first belts 22, they can also be positioned by the positioning device 1, which can ensure that the position of the plate materials 23 will not deviate greatly during the conveying process, and facilitate the conveying and detection of the plate materials 23.

[0036] In this embodiment, the rotating shaft 21 is fixed by only one support seat 2. Preferably, the first end 211 of the rotating shaft 21 is fixed on the support seat 2, thereby forming a cantilever structure. During installation, in order to ensure the consistency of each rotating shaft 21, it is only necessary to ensure the position of the support seat 2 of each rotating shaft 21. If the rotating shaft 21 is fixed by two support seats 2, it is necessary to ensure the position relationship of the two support seats 2 fixing the same rotating shaft 21, and the position relationship of the support seats 2 between different rotating shafts 21; and the two support seats 2 of the same rotating shaft 21 will also produce stuck, abnormal noise and other phenomena due to excessive coaxiality deviation, such as the solution shown in the patent document with application number CN201710430059, so the processing accuracy and installation requirements for the support seat 2 and the rotating shaft 21 will be much higher. Compared with the patent document with application number CN201710430059 which discloses a high-precision conveying device for transparent flat panel appearance inspection, the present embodiment has much lower installation requirements for the support seat 2 and the rotating shaft 21. Therefore, the machining accuracy of the support seat 2 and the rotating shaft 21, and the requirements for the degree of coordination during installation of each support seat 2 and each rotating shaft 21 are also much lower; at the same time, each support seat 2 can be installed independently with little mutual influence, and the replacement and installation of the first belt 22 are very convenient.

[0037] In this embodiment, as a further improvement of the above technical solution, the number of support seats 2 is at least three, and two rotating shafts 21 are rotatably provided on a support seat 2 located in the middle, wherein one rotating shaft 21 is connected to the rotating shaft 21 on the adjacent support seat 2 with at least two groups of first belts 22, and another rotating shaft 21 is connected to the rotating shaft 21 on the adjacent support seat 2 with two groups of second belts 24, and the upstream of the second belt 24 is connected to the downstream of the first belt 22, and a detection station is provided between the first belt 22 and the second belt 24. In this embodiment, the support seat 2 provided with two rotating shafts 21 can be defined as a double seat, and the support seat 2 provided with only one rotating shaft 21 can be defined as a single seat. A detection station can be provided between the second belt 24 and the first belt 22, such as a glass detection station, because there is a gap between the first belt 22 and the second belt 24, and the gap is formed by the gap between the two rotating shafts 21 on the double seat, and the glass in transit can be detected without obstruction by utilizing the gap, and the defects of the glass can be accurately detected. Theoretically, the double seat can be replaced by two parallel single seats, but using two parallel single seats instead of the double seat may cause the gap between the rotating shafts 21 on the parallel single seats to be too large, as well as some other situations in the actual production process. Therefore, it is more appropriate to use a double seat.

[0038] In this embodiment, as a further improvement of the above technical solution, a conveying mechanism for plate materials further includes a fixing frame 25, and the fixing frame 25 is fixedly arranged;

[0039] The first belt 22 and the second belt 24 are also provided with rollers 26, which are fixed on the fixing frame 25, and are tangent to the inner side of the first belt 22 or the inner side of the second belt 24. The rollers 26 support the first belt 22 and the second belt 24, and prevent the first belt 22 or the second belt 24 from sagging due to excessive gravity when the first belt 22 or the second belt 24 is conveying the plate material 23.

[0040] In the present embodiment, as a further improvement of the above technical solution, the first belt 22 and the second belt 24 are both round belts. When the round belts are used to convey the plate material 23, the round belts and the plate material 23 are tangent to each other. Therefore, there is line contact between the round belts and the plate material 23, which is convenient for positioning and conveying the plate material 23. The position of the plate material 23 during the conveying process is not prone to large deviations.

[0041] In this embodiment, as a further improvement of the above technical solution, the support seat 2 includes a seat body 27, a bearing 271 is embedded in the seat body 27, a step is present between the first end 211 of the rotating shaft 21 and the middle of the rotating shaft 21, the diameter of the first end 211 of the rotating shaft 21 is smaller than the inner diameter of the bearing 271, the diameter of the middle of the rotating shaft 21 is larger than the inner diameter of the bearing 271, the first end 211 of the rotating shaft 21 passes through the bearing 271 and is connected to the fixing ring 28, and the rotating shaft 21 is locked on the seat body 27 through the fixing ring 28;

[0042] The second end 212 of the rotating shaft 21 is provided with a belt installation groove 213, and each rotating shaft 21 is connected to the first belt 22 or the second belt 24 through the belt installation groove 213. The rotating shaft 21 can be clamped in the bearing 271 of the seat body 27 through the fixing ring 28 and the step formed between the first end 211 of the rotating shaft 21 and the middle part of the rotating shaft 21, so that the rotating shaft 21 will not shake along its axial direction. The fixing ring 28 can be a nut, and correspondingly, the first end 211 of the rotating shaft 21 can be provided with an external thread, and the nut is locked on the first end 211 of the rotating shaft 21 through a locking sleeve, so that the rotating shaft 21 can be locked on the seat body 27.

The screw rod 14 is provided with a first handle 141. The first adjustment plate 11 and the second adjustment plate 12 are respectively slidably clamped on the slide rod 15. The screw rod 14 can be rotated by the first handle 141. By rotating the screw rod 14, the left-handed nut 111 and the right-handed nut can be moved closer to or away from each other on the screw rod 14, so that the first adjustment plate 11 and the second adjustment plate 12 can be moved closer to or away from each other. The first adjustment plate 11 and the second adjustment plate 12 slide on the screw rod 14 and the slide rod 15. Preferably, two slide rods 15 can be provided. Therefore, the spacing between the first adjustment plate 11 and the second adjustment plate 12 can be adjusted by adjusting the screw rod 14. The left-handed nut 111 and the right-handed nut of this embodiment can be fixed on the first adjustment plate 11 or the second adjustment plate 12 by the fixing block 121. The appearance of the left-handed nut 111 and the right-handed nut is basically the same, and the difference is only that the internal threads are different.

[0045] Before the plate material 23 is transferred to the first belt 22, the plate material 23 is placed on the slide bar 15 and the screw rod 14. By adjusting the distance between the first adjustment plate 11 and the second adjustment plate 12, the plate material 23 can be clamped, thereby achieving the positioning of the plate material 23. After the plate material 23 is positioned, the plate material 23 can be transferred to the first belt 22.

A fixing pin 132 is provided on the fixing seat 131, and the fixing pin 132 is movably set to the screw rod 14 to fix the screw rod 14. After the spacing between the first adjustment plate 11 and the second adjustment plate 12 is adjusted, the fixing pin 132 can be used to hold the screw rod 14 to prevent the screw rod 14 from rotating, so that the position between the first adjustment plate 11 and the second adjustment plate 12 will not change. Preferably, a second handle 133 can be provided on the fixing pin 132.

When the plate material 23 is placed on the screw rod 14 and the slide rod 15, the two sides of the plate material 23 are in contact with the rollers 16 on the first adjustment plate 11 and the rollers 16 on the second adjustment plate 12, respectively, and the rollers 16 have a guiding effect on the plate material 23, and also facilitate the plate material 23 to slide between the first adjustment plate 11 and the second adjustment plate 12.
