Description

Technical Field

[0001] This utility model relates to feeding equipment, and more particularly to a glass screen flipping feeding equipment. Background Technology

[0002] In the glass screen production and assembly process, after the glass screen has been processed in the previous process, the sheet material is automatically placed in the material tray for discharge, and then proceeds to the next process. At this time, the glass screen needs to be flipped over to process the other side. However, at present, the sheet material is generally flipped manually, that is, the material tray containing the sheet material is inverted on another empty material tray to flip it over, and then the material is manually loaded for further processing. This is not only inefficient, but also has high labor costs. Utility Model Content

[0006] Preferably, the conveying mechanism includes two parallel gantry frames, which are fixedly connected to the frame platform. Each of the two gantry frames has a material picking component slidably connected to its upper end for picking up the material sheet from the material tray.

[0007] Preferably, the material handling assembly includes a support plate, a slider, a first cylinder, and two suction plates. A linear guide rail is provided on one side of the crossbeam of the gantry frame. The support plate is slidably connected to the linear guide rail.

[0010] Preferably, the conveying and flipping mechanism includes a conveying component and a flipping component. The conveying component is positioned across the transport direction end of the conveying guide mechanism and is slidably connected to the frame platform. The flipping component is rotatably connected to the discharge conveying mechanism near the end of the conveying guide mechanism for flipping the material sheet and placing it on the discharge conveying mechanism.

[0011] Preferably, the conveying assembly includes a support frame, several third cylinders, and several suction cup holders.

[0014] The technical solution of this utility model has the following beneficial effects: During feeding, the lifting mechanism of the feeding hopper descends, causing the material tray at the bottom of the hopper to come into contact with the conveying mechanism. Under the action of friction, the conveying mechanism pulls out the bottommost material tray and transports it to the area below the handling mechanism. After the conveying mechanism pulls the material tray out of the feeding hopper, the other material trays in the hopper slide down onto the support plate of the lifting mechanism under the action of gravity. The lifting mechanism lifts the remaining material trays to prevent them from being pulled out further until the next feeding is needed. The lifting mechanism then descends again, and the handling mechanism removes the material from the trays and transports them to the conveying guide mechanism. The conveying guide mechanism adjusts the material... The material sheet is positioned correctly and transported to the handling and flipping mechanism. The handling and flipping mechanism then flips the material sheet and transports it to the unloading conveyor for loading, thus achieving automatic flipping and loading of the material sheet, improving production efficiency and reducing labor costs. When collecting empty material trays, the lifting component of the empty tray hopper lowers so that the pallet is level with the conveying plane of the conveying mechanism. The conveying mechanism sends the empty pallet into the empty tray hopper. When collecting empty material trays again, the lifting mechanism of the empty tray hopper lowers so that the top empty material tray is level with the conveying plane of the transmission mechanism. The conveying mechanism stacks the empty material trays on top of the trays, and so on, to achieve the rotation of collecting empty material trays. Attached Figure Description

[0027] This utility model proposes a flipping and feeding device.

[0028] like Figures 1 to 2As shown in one embodiment of this utility model, the flipping and feeding device includes a frame platform 1. A feeding bin 2 is provided at one end of the frame platform 1, and an empty tray bin 3 is provided at the other end. A conveying mechanism 8 is provided between the feeding bin 2 and the empty tray bin 3, with one end of the conveying mechanism 8 extending to the bottom of the feeding bin 2. A limiting strip 23 for limiting the tray is provided near the end of the feeding bin 2 close to the conveying mechanism 8 to prevent other trays from being pulled out along with the tray when the conveying mechanism 8 pulls out the tray. Therefore, the limiting strip 23 is positioned above the conveying plane of the conveying mechanism 8, with the bottom of the limiting strip 23 being a certain distance from the conveying mechanism. The distance between the conveying planes of 8 is higher than the thickness of one tray and lower than the thickness of two trays. Lifting mechanisms 21 are provided in both the upper material bin 2 and the empty tray bin 3 to lift or lower the trays. A conveying guide mechanism 5 is provided on one side of the conveying direction of the conveying mechanism 8 for transporting the material pieces and adjusting their positions. A handling mechanism 4 is provided across the conveying mechanism 8 for taking out the material pieces from the trays and transferring them to the conveying guide mechanism 5. A handling and flipping mechanism 6 is provided at one end of the conveying direction of the conveying guide mechanism 5 for handling and flipping the material pieces. The end of the handling and flipping mechanism 6 opposite to the conveying guide mechanism 5 is connected to the discharge conveying mechanism 7.

[0029] In this embodiment, during material loading, the lifting mechanism 21 of the loading hopper 2 descends, causing the bottom tray of the hopper to come into contact with the conveying mechanism 8. Under the action of friction, the conveying mechanism 8 pulls out the bottom tray and transports it below the transport mechanism 4. After the conveying mechanism 8 pulls the tray out of the loading hopper 2, the other trays in the hopper slide down onto the support plate 211 of the lifting mechanism 21 under the action of gravity. The lifting mechanism 21 lifts the remaining trays to prevent them from being pulled out again until the next time material is needed. When empty trays are collected, the lifting assembly of the empty tray hopper 3 descends, making the support plate 211 horizontal with the conveying plane of the conveying mechanism 8. The conveying mechanism 8 then transports the empty tray... Plate 211 is sent to the empty tray hopper 3. When the empty trays are collected, the lifting mechanism 21 of the empty tray hopper 3 is lowered so that the uppermost empty tray is level with the transmission plane of the transmission mechanism. The transmission mechanism 8 stacks the empty trays on the top of the trays, and so on, so as to realize the rotation of the empty trays. Meanwhile, the handling mechanism 4 takes out the material pieces from the trays and transports them to the conveying guide mechanism 5. The conveying guide mechanism 5 adjusts the position of the material pieces and transports them to the handling and flipping mechanism 6. Then, the handling and flipping mechanism 6 flips the material pieces and transports them to the discharge conveying mechanism 7 for loading. This realizes the automatic flipping and loading of material pieces, improves production efficiency and reduces labor costs.

[0041] Optionally, in some feasible embodiments, the flipping assembly 62 structure may include multiple suction cup frames 614, a rotating shaft 622, and a drive motor 621.

[0047] Specifically, the working principle and usage process of this utility model are as follows: During feeding, the lifting mechanism 21 of the feeding hopper 2 descends, causing the bottom tray of the hopper to come into contact with the conveying mechanism 8. Under the action of friction, the conveying mechanism 8 pulls out the bottom tray and transports it to the area below the handling mechanism 4. After the conveying mechanism 8 pulls the tray out of the feeding hopper 2, the other trays in the hopper slide down onto the support plate 211 of the lifting mechanism 21 under the action of gravity. The lifting mechanism 21 lifts up the remaining trays to prevent them from being pulled out again until the next feeding is needed. The lifting mechanism 21 then descends again, and the handling mechanism 4 removes the material from the trays and transports it to the conveying guide mechanism 5. After adjusting the position of the material sheet, the material sheet is transported to the handling and flipping mechanism 6. Then, the handling and flipping mechanism 6 flips the material sheet and transports it to the unloading and conveying mechanism 7 for loading, thereby realizing automatic flipping and loading of the material sheet, improving production efficiency and reducing labor costs. When collecting empty material trays, the lifting component of the empty tray hopper 3 lowers so that the pallet 211 is level with the conveying plane of the conveying mechanism 8. The conveying mechanism 8 sends the empty pallet 211 into the empty tray hopper 3. When collecting empty material trays, the lifting mechanism 21 of the empty tray hopper 3 lowers so that the uppermost empty material tray is level with the conveying plane of the transmission mechanism. The conveying mechanism 8 stacks the empty material trays on the top of the trays, and so on, realizing the rotation of collecting empty material trays.
