Description

Technical Field

[0001] The utility model relates to the technical field of flatness detection, in particular to a glass panel flatness rapid detection jig. Background Art

[0002] A glass panel is a thin piece of glass with an extremely flat surface and is a basic component of a liquid crystal display device. A glass panel flatness detection jig is a special tool or equipment used to detect the surface flatness of a glass panel. Existing detection methods mainly include: multi-point measurement method, light projection method and laser scanning method. Among them, the laser scanning method uses a non-contact laser scanning method to collect a large amount of surface data to generate a three-dimensional model. The surface flatness of the three-dimensional model is calculated to determine the flatness of the glass. During the scanning and detection process, the panel is driven to move by a matching mobile device, thereby performing a comprehensive scan of the panel.

[0003] Although the detection fixture in the prior art has many benefits during use, it still has the following problems: its limitation on the panel is not perfect, which makes it impossible to adapt the moving position of the scanning module to the panel, resulting in the moving trajectory of the scanning module detection being unable to adapt to panels of different sizes, affecting the detection efficiency of the scanning module on the panel.

[0013] Specifically, a pressure sensor is provided on the outer wall of one end of the push rod body, and the pressure sensor is connected to the outer wall of the connecting frame.

[0014] By adopting the above technical solution, the extrusion force generated when the conveyor belt contacts the glass panel can be transmitted to the connecting frame, and the pressure sensor detects the extrusion force and transmits it to the external controller.

[0015] Specifically, one end of the connecting frame is designed in an inclined shape, the transmission roller passes through the outer wall of one end of the connecting frame, and a driving motor is provided. The driving motor is connected to the outer wall of the upper end of the connecting frame.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the utility model describes a glass panel flatness rapid detection jig, comprising a frame 1, a supporting frame 2, a fixing frame 3 and a connecting frame 4. The supporting frame 2 is installed on one side of the outer wall of the upper end of the frame 1, movable grooves 11 are opened on both sides of the inner wall of the frame 1, and the connecting frame 4 is arranged inside the movable groove 11. The outer walls of both sides of the frame 1 are symmetrically provided with fixing frames 3, and a push rod body 33 is installed inside the fixing frame 3. The outer wall of the lower end of the connecting frame 4 is rotatably installed with equidistant and parallel transmission rollers 41, and the outer wall of the transmission roller 41 is sleeved with a conveyor belt 43.

[0031] When in use, the connecting frame 4, the transmission roller 41 and the conveyor belt 43 can move inside the movable groove 11, so that the conveyor belt 43 moves to the inside of the frame 1, the support frame 2 keeps the use position of the screw body 21 stable, and can lift the screw body 21 to prevent the scanning module 22 from contacting the glass panel, the fixed frame 3 keeps the use position of the push rod body 33 stable, the push rod body 33 can push the connecting frame 4 to move and adjust the use position of the connecting frame 4, the transmission roller 41 drives the conveyor belt 43 to rotate, so that the conveyor belt 43 assists the glass panel to move.

[0032] For example, in order to move the glass panel, Figure 2 As shown, the inner wall of the frame 1 is rotatably mounted with equidistant and parallel driving rollers 12 , and the upper end surface of the driving roller 12 is in the same horizontal plane as the lower end of the inner wall of the movable groove 11 .

[0033] When in use, the external power mechanism drives the driving roller 12 to rotate in a circular motion, thereby moving the glass panel placed on the upper end of the driving roller 12 .

[0034] For scanning detection, for example, Figure 3 As shown, a lead screw body 21 is installed on one side of the upper end of the inner wall of the support frame 2, and a scanning module 22 is installed on the outer wall of the lower end of the lead screw body 21.

[0035] During use, the screw body 21 maintains a stable use position through the support frame 2. The screw body 21 can adjust the use position of the scanning module 22 and the scanning position of the scanning module 22 to ensure that the scanning module 22 can scan and detect different positions of the glass panel. The screw body 21 can adaptively adjust the moving range of the scanning module 22 according to the pushing distance of the push rod body 33 to ensure that the scanning range of the scanning module 22 is adapted to different glass panel sizes.

[0036] For fixation, exemplary, such as Figure 4 As shown, fixing blocks 31 are installed on both sides of the outer wall of the upper end of the fixing frame 3. Bolts 32 are provided inside the fixing blocks 31, and the fixing blocks 31 are connected to the outer wall of the frame 1 through the bolts 32.

[0037] When in use, the fixing block 31 is kept in a stable position outside the frame 1 by the bolts 32 , thereby achieving the purpose of fixing the fixing frame 3 and ensuring that the use position of the push rod body 33 is stable.

[0038] In order to detect the extrusion force, for example, Figure 4 As shown, a pressure sensor 34 is provided on the outer wall of one end of the push rod body 33 , and the pressure sensor 34 is connected to the outer wall of the connecting frame 4 .

[0039] During use, the squeezing force generated when the conveyor belt 43 contacts the glass panel can be transmitted to the connecting frame 4 , and the pressure sensor 34 detects the squeezing force and transmits it to the outside controller.

[0040] To adjust the position of the glass panel, for example, Figure 1 As shown, one end of the connecting frame 4 is designed in an inclined shape, a transmission roller 41 passes through the outer wall of one end of the connecting frame 4 and a driving motor 42 is provided. The driving motor 42 is connected to the outer wall of the upper end of the connecting frame 4.

[0041] When in use, the driving motor 42 drives the conveyor belt 43 to rotate in a circular motion. The rotation of the conveyor belt 43 can assist the movement of the glass panel, and the inclined surface of the conveyor belt 43 can guide the movement trajectory of the glass panel, so that the glass panel moves toward the center position of the frame 1.

[0042] In order to control the position of the conveyor belt 43, for example, Figure 5 As shown, a guide roller 44 is rotatably mounted on the outer wall of one side of the connecting frame 4, and the guide roller 44 contacts the outer wall of the conveyor belt 43.

[0043] When in use, the guide roller 44 limits the rotation trajectory of the conveyor belt 43 to ensure that the conveyor belt 43 rotates outside the transmission roller 41.

[0044] When the utility model is in use, the staff manually carries the glass panel and places it on the upper end of the driving roller 12 on the left side, and the external power mechanism drives the driving roller 12 to rotate in a circular motion, thereby moving the glass panel placed on the upper end of the driving roller 12 and moving the glass panel toward the support frame 2;

[0045] The push rod body 33 pushes the connecting frame 4 to move inside the movable groove 11, so that the conveyor belt 43 squeezes the glass panel, and the inclined conveyor belt 43 can push the glass panel toward the center of the frame 1 until the glass panel is clamped by the two conveyor belts 43 and moves between the two conveyor belts 43;

[0046] The driving motor 42 drives the transmission roller 41 to rotate, thereby driving the conveyor belt 43 to rotate, which can assist the movement of the glass panel.

[0047] When the conveyor belt 43 presses the side of the glass panel, the pressure sensor 34 detects the squeezing pressure of the conveyor belt 43 on the glass panel. Based on the detection data of the pressure sensor 34, the external controller controls the push rod body 33 to stop and position, so as to keep the use position of the connecting frame 4 and the conveyor belt 43 stable. The two conveyor belts 43 can limit the movement range of the glass panel. The distance pushed by the push rod body 33 against the connecting frame 4 can be used to know the distance between the conveyor belts 43, and thus the size of the glass panel.

[0048] The controller controls the operation of the lead screw body 21 according to the size of the glass panel. The lead screw body 21 carries the scanning module 22 to move, and can adjust the moving range of the scanning module 22 in time to ensure that the scanning range of the scanning module 22 is compatible with the size of the glass panel.
