Description

Technical Field

[0001] The present application relates to the technical field of transmission equipment, and in particular to a cover plate transmission mechanism. Background Art

[0002] After the glass cover plate is produced, it is generally necessary to transport it to a designated location through a transport device to facilitate further processing or packaging of the glass cover plate.

[0003] The existing method of cover plate transmission is usually carried out by simple conveyor belts and other equipment. Although the cover plate can be transmitted to a certain extent, the transmission accuracy is poor, which seriously affects the subsequent processing of the cover plate. Utility Model Content

[0004] The purpose of the utility model is to solve or at least alleviate the problem that the existing method of cover plate transmission is usually carried out by simple conveyor belts and other equipment. Although the cover plate can be transmitted to a certain extent, the transmission accuracy is poor, which seriously affects the subsequent processing of the cover plate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cover plate transmission mechanism comprises a frame with transmission shafts rotatably connected at both ends, a transmission structure is installed on the transmission shaft, the transmission structure comprises a plurality of transmission belts sleeved on two transmission shafts and drivingly connected to the transmission shafts, gaps with a width smaller than the width of the cover plate are left between adjacent transmission belts, an optical fiber detector is installed below the output end of the transmission structure, an electric slide rail is installed on the frame on one side of the optical fiber detector, the electric slide rail is connected to an electric clamp for clamping the cover plate through an electric slider, and a programmable controller electrically connected to the optical fiber detector, the electric slider and the electric clamp is also installed on the frame.

[0007] By adopting the above technical solution, when using, the user first starts the motor to drive the transmission shaft to rotate, thereby driving the multiple transmission belts connected to the transmission shaft to rotate synchronously. At this time, the user can place the cover plate on the transmission belt. During the transmission of the transmission belt, the electric telescopic rods installed above the two side racks repeatedly extend and retract to push the push plates on both sides to move toward the transmission belt in the middle, and push the cover plate that is offset during transmission to the middle of the transmission structure, so that the cover plate can be accurately moved to the top of the optical fiber detector. At this time, the optical fiber detector detects the cover plate and immediately transmits the signal to the programmable controller. The programmable controller controls the electric clamp to start the electric clamp to clamp the cover plate above the optical fiber detector. At the same time, the programmable controller controls the electric slide to start, push the electric slider to move, move the electric clamp holding the cover plate to the other end of the electric slide, and control the electric clamp to put down the clamped cover plate, so as to achieve accurate feeding of the cover plate, and try to avoid the existing method that the cover plate transmission is usually carried out by simple conveyor belts and other equipment. Although the transmission of the cover plate can be achieved to a certain extent, the transmission accuracy is poor, which seriously affects the subsequent processing of the cover plate.

[0008] Optionally, a motor is fixedly connected to the outer wall of one end of the frame, the output end of the motor passes through the frame and is fixedly connected to the end of the transmission shaft, and a bearing is installed at the connection between the output end of the motor and the frame.

[0009] By adopting the above technical solution, a motor is set to drive the transmission shaft to rotate, thereby driving the transmission belt to rotate and realizing the transmission of the cover plate. A bearing is set to reduce the friction at the connection between the motor output end and the frame, thereby reducing the resistance effect when the transmission shaft rotates.

[0010] Optionally, both transmission shafts are in the form of round rollers, and the outer surfaces of the two transmission shafts are provided with a plurality of annular grooves corresponding to the transmission belts.

[0011] By adopting the above technical solution, an annular groove is opened on the outer surface of the transmission shaft to limit the transmission belt, so as to avoid the transmission belt from moving along the length direction of the transmission shaft during the transmission process, which will increase the spacing between adjacent transmission belts and affect the transmission of the cover plate.

[0012] Optionally, support plates are fixedly connected to the upper surfaces of both sides of the middle section of the frame, electric telescopic rods are fixedly connected to adjacent sides of the two support plates, and a push plate with a bottom height lower than the upper surface height of the cover plate is fixedly connected to the output end of the electric telescopic rod.

[0013] By adopting the above technical solution, during the cover plate transmission process, the electric telescopic rod repeatedly extends and retracts, pushing the two push plates to move toward each other, pushing the cover plate that has been offset during the transmission process back to the center of the transmission structure, and avoiding the problem that the optical fiber detector cannot detect the cover plate as much as possible.

[0014] Optionally, a material storage structure is provided in front of the output end of the transmission structure. When the electric slider moves to one end of the electric slide rail, the electric clamp is located just above the optical fiber detector. When the electric slider moves to the other end of the electric slide rail, the electric clamp is located just above the material storage structure.

[0015] By adopting the above technical solution, when the electric clamp moves to above the optical fiber detector, it can clamp the cover plate on the transmission structure, and then move the electric clamp along the electric slide rail to above the material storage structure to place the cover plate in the material storage structure.

[0016] Optionally, the material storage structure includes a material storage box with an opening on one side, both sides of the material storage box are fixedly connected to the inner wall of the frame through connecting plates, and the cross-sectional size of the inner cavity of the material storage box is adapted to the size of the cover plate.

[0017] By adopting the above technical solution, a storage box is set up to collect the transmitted cover plates, and the cross-sectional size of the inner cavity of the storage box is adapted to the size of the cover plates, so that the multiple layers of cover plates in the storage box can be neatly aligned, which is convenient for subsequent processing of the cover plates.

[0018] Optionally, a slide plate is slidably connected to the inner cavity of the storage box, four sliding tubes are distributed in a matrix on the inner wall of the storage box below the slide plate, a sliding rod is slidably connected to the top of the sliding tube, and a spring is fixedly connected to one end of the sliding rod located in the inner cavity of the sliding tube.

[0019] By adopting the above technical scheme, when the transmission amount of the cover plates is small, the cover plates can be taken out from the storage box for subsequent processing. When the number of cover plates on the transmission structure is too large, resulting in a large number of cover plates piled up above the slide plate, the cover plates can press down the slide bar under the action of their own gravity, causing the slide bar to slide into the slide tube, thereby squeezing the spring to contract. When the number of cover plates on the slide plate decreases, the total weight of the cover plates decreases, and the squeezing effect on the spring is reduced. At this time, the spring can push the slide plate upward under the action of its own restoring force, so that the cover plates on the top layer are always flush with the top of the storage box, making it convenient to take out the cover plates from the storage box for subsequent processing.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application achieves accurate feeding of the cover plates by coordinating the structures such as the transmission belt, the fiber optic detector, the electric slide rail and the electric clamp. Since gaps are left between the multiple transmission belts, the fiber optic detector installed under the transmission belt can detect the cover plates transmitted on the transmission belt. After the cover plates move to above the fiber optic detector, the programmable controller immediately controls the electric clamp to start clamping the cover plates, and lowers the cover plates after moving along the electric slide rail to a suitable position, thereby avoiding the existing method of cover plate transmission usually carried out by simple conveyor belts and other equipment. Although the cover plates can be transmitted to a certain extent, the transmission accuracy is poor, which seriously affects the subsequent processing of the cover plates.

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3 A cover plate transmission mechanism includes a frame 1 with transmission shafts 2 rotatably connected at both ends, a transmission structure is installed on the transmission shaft 2, and the frame 1 is set to support the transmission structure. When in use, the user can place the cover plate on the transmission structure, and the cover plate is transported to a designated position through the transmission structure.

[0028] The transmission structure includes a plurality of transmission belts 5 which are sleeved on two transmission shafts 2 and transmission-connected to the transmission shafts 2. A gap with a width smaller than the width of the cover plate is left between adjacent transmission belts 5, so as to prevent the cover plate from falling from the gap between the two transmission belts 5 during the transmission process, thereby causing damage to the cover plate.

[0029] An optical fiber detector 6 is installed below the output end of the transmission structure. Since there are gaps between the multiple transmission belts 5, the optical fiber detector 6 located below can detect whether there is a cover plate on the transmission belt 5 located above.

[0030] An electric slide rail 10 is installed on the frame 1 on one side of the optical fiber detector 6. The electric slide rail 10 is connected to an electric clamp 12 for clamping the cover plate through an electric slider 11. When the optical fiber detector 6 detects that the cover plate moves above it, the electric clamp 12 immediately starts to clamp the cover plate. Then the electric slide rail 10 is energized to drive the electric clamp 12 installed on the electric slider 11 to move, and move the clamped cover plate to a designated position for storage.

[0031] The frame 1 is also equipped with a programmable controller 18 electrically connected to the optical fiber detector 6, the electric slide 11 and the electric clamp 12. The programmable controller 18 is provided for the staff to program, so as to realize the automatic clamping of the cover plate by the clamp 12, the automatic movement of the electric slide 10 to drive the electric clamp 12, and the automatic opening and lowering of the cover plate by the electric clamp 12 after the cover plate is moved to the specified position, without manual control, and is more convenient and quick to use.

[0032] Reference Figure 1 A motor 4 is fixedly connected to the outer wall of one end of the frame 1. The output end of the motor 4 passes through the frame 1 and is fixedly connected to the end of the transmission shaft 2. A bearing is installed at the connection between the output end of the motor 4 and the frame 1. The motor 4 is used to drive the transmission shaft 2 to rotate, thereby driving the transmission belt 5 to rotate to achieve the transmission of the cover plate. The bearing is used to reduce the friction at the connection between the output end of the motor 4 and the frame 1, thereby reducing the resistance effect when the transmission shaft 2 rotates.

[0033] Reference Figure 1 The two transmission shafts 2 are both in a round roller structure, and a plurality of annular grooves 3 corresponding to the transmission belts 5 are provided on the outer surfaces of the two transmission shafts 2. The annular grooves 3 provided on the outer surfaces of the transmission shafts 2 are used to limit the transmission belts 5, and to avoid the transmission belts 5 from moving along the length direction of the transmission shafts 2 during the transmission process, which would increase the spacing between adjacent transmission belts 5 and affect the transmission of the cover plate.

[0034] Reference Figure 2 , support plates 7 are fixedly connected to the upper surfaces of both sides of the middle section of the frame 1, and electric telescopic rods 8 are fixedly connected to the adjacent sides of the two support plates 7, and a push plate 9 whose bottom height is lower than the upper surface height of the cover plate is fixedly connected to the output end of the electric telescopic rod 8. During the cover plate transmission process, the electric telescopic rod 8 repeatedly extends and retracts, pushing the two push plates 9 to move toward each other, pushing the cover plate that has been offset during the transmission process back to the center of the transmission structure, and trying to avoid the problem that the optical fiber detector 6 cannot detect the cover plate.

[0035] Reference Figure 3 A material storage structure is provided in front of the output end of the transmission structure. When the electric slider 11 moves to one end of the electric slide rail 10, the electric clamp 12 is just located above the optical fiber detector 6. When the electric slider 11 moves to the other end of the electric slide rail 10, the electric clamp 12 is just located above the material storage structure. When the electric clamp 12 moves to the optical fiber detector 6, it can clamp the cover plate on the transmission structure, and then move the electric clamp along the electric slide rail 10 to the top of the material storage structure to place the cover plate in the material storage structure.

[0036] Reference Figure 1 and Figure 3The storage structure includes a storage box 13 with an opening on one side. Both sides of the storage box 13 are fixedly connected to the inner wall of the frame 1 through connecting plates. The size of the inner cavity of the storage box 13 is adapted to the size of the cover plate. The storage box 13 is used to collect the transferred cover plates. The size of the inner cavity of the storage box 13 is adapted to the size of the cover plate, which can make the multi-layer cover plates in the storage box 13 aligned and convenient for subsequent processing of the cover plates.

[0037] Reference Figure 3 The inner cavity of the storage box 13 is slidably connected with a slide plate 14, and four slide tubes 15 are arranged in a matrix on the inner wall of the storage box 13 below the slide plate 14. The top of the slide tube 15 is slidably connected with a slide rod 16, and a spring 17 is fixedly connected to one end of the slide rod 16 located in the inner cavity of the slide tube 15. When the transmission amount of the cover plate is small, the cover plate can be taken out from the storage box 13 for subsequent processing. When the number of cover plates on the transmission structure is too large, resulting in a large number of cover plates piled up on the slide plate 14, the cover plate can press down the slide rod 16 under its own gravity, so that the slide rod 16 slides into the slide tube 15, thereby squeezing the spring 17 to contract. When the number of cover plates on the slide plate 14 is reduced, the total weight of the cover plate is reduced, and the squeezing effect on the spring 17 is reduced. At this time, the spring 17 can push the slide plate 14 upward under the action of its own restoring force, so that the cover plate located on the top layer is always flush with the top of the storage box 13, which is convenient for taking out the cover plate from the storage box 13 for subsequent processing.

[0038] The implementation principle of the present application is as follows: when in use, the user first starts the motor 4 to drive the transmission shaft 2 to rotate, thereby driving the multiple transmission belts 5 connected to the transmission shaft 2 to rotate synchronously. At this time, the user can place the cover plate on the transmission belt 5. During the transmission process of the transmission belt 5, the electric telescopic rods 8 installed above the two side racks 1 repeatedly extend and retract to push the push plates 9 on both sides to move toward the transmission belt 5 located in the middle, and push the cover plate that is offset during transmission to the middle of the transmission structure, so that the cover plate can be accurately moved above the optical fiber detector 6. At this time, the optical fiber detector 6 detects the cover plate and immediately transmits the signal to the programmable controller. 18. The programmable controller 18 controls the electric clamp 12 to start the electric clamp 12 to clamp the cover plate above the optical fiber detector 6. At the same time, the programmable controller 18 controls the electric slide 10 to start, pushes the electric slider 11 to move, moves the electric clamp 12 holding the cover plate to the other end of the electric slide 10, and controls the electric clamp 12 to put down the clamped cover plate, so as to achieve accurate feeding of the cover plate, and try to avoid the existing method of cover plate transmission usually using simple conveyor belts and other equipment. Although the cover plate can be transmitted to a certain extent, the transmission accuracy is poor, which seriously affects the subsequent processing of the cover plate.
