DETAILED DESCRIPTION

[0017] Embodiment 1

[0018] like Figure 1 to Figure 2 As shown, a mask piece clamping and feeding device proposed in the utility model includes a frame 1, a feeding mechanism, and a conveyor belt mechanism 6; the frame 1 is connected to a feeding mechanism through a first driving mechanism, and the feeding mechanism is driven by the first driving mechanism to adjust the horizontal movement, and two groups of feeding mechanisms are provided. The two groups of feeding mechanisms are driven by the first driving mechanism to correspond alternately with the conveyor belt mechanism 6, so that the two groups of feeding mechanisms can work alternately, improve the working continuity, and improve the processing efficiency; the feeding mechanism is arranged on the frame 1 and is located above the feeding mechanism, and the feeding mechanism is used to suck the mask piece in the feeding mechanism to complete the material removal; the conveyor belt mechanism 6 is arranged at the output end of the feeding mechanism, and the conveyor belt mechanism 6 is used to receive the mask piece conveyed by the feeding mechanism to complete the feeding.

[0019] Furthermore, the loading mechanism includes a second driving mechanism 5 and a vacuum pump 501; the second driving mechanism 5 is arranged at the top of the frame 1, and the second driving mechanism 5 is driven and connected to a vacuum suction cup 503, and the vacuum suction cup 503 is driven by the second driving mechanism 5 to adjust its position in the horizontal direction and the height direction along the frame 1; the second driving mechanism 5 is composed of a transverse electric slide rail and an electric telescopic rod, and the transverse electric slide rail can drive the electric telescopic rod to move and adjust in the horizontal direction, and the electric telescopic rod drives the vacuum suction cup 503 to move and adjust in the vertical direction; the vacuum pump 501 is installed at the top of the second driving mechanism 5, and the vacuum pump 501 is connected to a vacuum tube 502, and the other end of the vacuum tube 502 is connected to the vacuum suction cup 503.

[0020] Furthermore, the feeding mechanism includes a loading box 2 and a material placement seat 3; the loading box 2 is driven by a first driving mechanism to perform horizontal movement adjustment; the first driving mechanism is composed of a motor-driven threaded rod, the motor and the threaded rod are arranged at the bottom end of the frame 1, the bottom end of the loading box 2 is slidably connected to the frame 1, the threaded rod is threadedly connected to the bottom end of the loading box 2, and the rotation of the threaded rod driven by the motor can drive the loading box 2 to move horizontally along the bottom end of the frame 1; the material placement seat 3 is slidably connected to the inner wall of the loading box 2, and a spring 302 is installed between the material placement seat 3 and the bottom end of the loading box 2.

[0021] In this embodiment, a proper amount of mask sheets are placed on the two groups of feeding mechanisms respectively. When the mask sheets are placed on the material placement seat 3, the material placement seat 3 is pressed downward along the inner wall of the feeding box 2 under the action of the mask sheets' own gravity, so that the spring 302 is compressed. As the vacuum suction cup 503 in the feeding mechanism absorbs and takes materials, the gravity exerted on the material placement seat 3 becomes smaller, and the spring 302 gradually drives the material placement seat 3 to slide upward along the inner wall of the feeding box 2 to restore to the initial position, thereby facilitating the vacuum suction cup 503 to absorb; the vacuum suction cup 503 is driven to start by the second driving mechanism 5 03 moves toward one of the feeding mechanisms, starts the vacuum pump 501, sucks the top group of mask pieces through the vacuum tube 502 and the vacuum suction cup 503, and drives it to move toward the conveyor belt mechanism 6, and finally unloads the sucked masks on the conveyor belt mechanism 6 for transmission. After the mask pieces on one of the feeding mechanisms are taken out, the two feeding mechanisms are driven to move horizontally through the first driving mechanism, so that the other feeding mechanism drives the mask pieces to move to the position corresponding to the conveyor belt mechanism 6, which is convenient for the feeding mechanism to continue working and improves the feeding efficiency.

[0022] Embodiment 2

[0023] like Figure 2 As shown, the mask sheet clamping and feeding device proposed by the utility model, compared with the first embodiment, the feeding mechanism also includes a sorting component; the sorting component is used to sort the mask sheets on the material placement seat 3 to prevent the vacuum suction cup 503 from tilting or stacking during the material picking process, and the sorting component includes a slide plate 4, a sorting plate 401 and a gear 402; the slide plate 4 is provided with two groups, and the two groups of slide plates 4 are symmetrically slidably connected to the side walls of the loading box 2, and a slide groove 201 adapted to the slide plate 4 is provided on the inner wall of the loading box 2, so that the slide plate 4 can only be adjusted up and down along the inner wall of the loading box 2; the slide plate 4 is connected to the side wall of the material placement seat 3 through a connecting block; the sorting plate 401 is provided with two groups and corresponds to the slide plate 4, the sorting plate 401 is slidably connected to the bottom end of the loading box 2, and the material placement seat 3 is provided with a channel 301 adapted to the sorting plate 401. A limit seat 202 adapted to the sorting plate 401 is provided at the bottom end of the loading box 2, so that the sorting plate 401 can always slide up and down along the loading box 2; racks are provided on the slide plate 4 and the sorting plate 401; the gear 402 is rotatably connected to the bottom end of the loading box 2, and the loading box 2 is meshed and connected with the racks installed on the slide plate 4 and the sorting plate 401.

[0024] In this embodiment, an appropriate amount of mask sheets are placed between the two groups of channels 301, and the material placement seat 3 is pressed down along the loading box 2 under the action of the mask sheet's own gravity, while driving the slide plate 4 to slide downward along the slide groove 201, and then the toothed plate on the slide plate 4 moves downward to drive the gear 402 to rotate, and the gear 402 drives the toothed plate on the sorting plate 401 to move upward along the limiting seat 202, and finally drives the sorting plate 401 to slide upward until the top of the sorting plate 401 passes through the channel 301 and moves above the material placement seat 3, and the two groups of sorting plates 401 clamp the two sides of the mask sheet and limit them, and at the same time, the rear end of the mask sheet is abutted against a side wall of the loading box 2 close to the conveyor belt mechanism 6 to ensure the neatness of the mask sheet, so as to facilitate the rapid absorption of the vacuum suction cup 503 and improve the feeding efficiency.

[0025] Embodiment 3

[0027] In this embodiment, when the vacuum suction cup 503 in the feeding mechanism conveys the adsorbed mask piece to the conveyor belt mechanism 6, the mask piece will be slightly adsorbed and deformed due to the suction force, and the pressing roller 704 is driven by the motor to rotate, and cooperates with the conveyor belt on the conveyor belt mechanism 6 to squeeze and flatten the mask piece, while continuing to convey it to avoid deformation of the mask piece. In order to further improve the leveling effect, the screw 701 can be rotated to drive the mounting frame 703 to adjust the appropriate height downward or upward under the guidance of the telescopic rod 702 to adjust the contact force of the pressing roller 704 on the mask piece, or a heating mechanism is set in the pressing roller 704, the heating mechanism is not drawn, so that the pressing roller 704 rolls and flattens the mask piece while ironing and flattening it, thereby further improving the leveling efficiency.
