[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in FIGS. 3 and 4 , a cutting device is proposed in this embodiment, including a processing seat 1 and a first bracket 5. A slide 2 and a slitting device are provided at the upper end of the processing seat 1. The slide 2 is slidably connected to the processing seat 1. A conveyor belt 6 is provided at the upper end of the first bracket 5. A second bracket 7 is provided between the processing seat 1 and the first bracket 5.

[0024] The display panel to be cut is pre-fixed on the slide 2, and the slide 2 slides along the upper end of the processing seat 1. When the slide 2 moves below the slitting device, the slitting device cuts the display panel. The horizontal movement of the slide 2 is controlled by a linear transmission mechanism, which will not be described in detail here.

[0025] The upper end of the second bracket 7 is provided with a rocker arm 13, a rotating bracket and a vacuum adsorption plate, and the vacuum adsorption plate is rotatably connected to the upper end of the rocker arm 13 for grabbing the display screen on the slide 2;

[0026] The rotating bracket is fixed to the lower end of the rocker arm 13, and is used to control the rotation of the rocker arm 13 and move the vacuum adsorption plate above the conveyor belt 6. The upper end of the second bracket 7 is provided with a flipping mechanism for controlling the vacuum adsorption plate to rotate and flip when moving.

[0027] When taking materials, the rotating bracket controls the rocker arm 13 to rotate, and the rocker arm 13 presses the vacuum adsorption plate on the upper end of the slide 2 during the rotation, and the vacuum adsorption plate grabs the display panel on the upper end of the slide 2. After the grabbing is completed, the rotating bracket controls the rocker arm 13 to rotate, and the vacuum adsorption plate is sent to the top of the conveyor belt 6.

[0028] During the rotation of the rocker arm 13, the flipping mechanism will control the rotation of the vacuum adsorption plate. When the vacuum adsorption plate is sent to the top of the conveyor belt 6, the display screen on the vacuum adsorption plate will be in an automatic downward state. After stopping the grabbing, the conveyor belt 6 can automatically send out the cut display screen. It can automatically complete the flipping when taking and releasing the material. It has a simple structure, a high degree of integration, and is convenient for personnel to control.

[0029] About slitting equipment:

[0030] The slitting device comprises a fixed seat 3 , which is fixedly connected to the upper end of the processing seat 1 . A cutter 4 is provided on the side of the fixed seat 3 facing the second bracket 7 , and the cutter 4 is slidably connected to the fixed seat 3 .

[0031] When the slide 2 moves to the bottom of the cutter 4, the cutter 4 will fall down to cut the display screen on the upper end of the slide 2. The horizontal movement of the cutter 4 is controlled by a linear transmission mechanism, which will not be described in detail here.

[0032] The specific structure of the rotating bracket is shown in the following description.

[0033] The rotating bracket includes a mounting seat 17 and a motor 8, the mounting end of the motor 8 is fixedly connected to the mounting seat 17, the output end of the motor 8 is fixedly connected to the lower end of the rocker arm 13, and the mounting seat 17 is fixedly connected to the upper end of the second bracket 7. The motor 8 is fixed to the second bracket 7 through the mounting seat 17, and the rotation of the rocker arm 13 is controlled by the motor 8.

[0034] About vacuum adsorption board:

[0035] The vacuum adsorption plate includes a pick-up plate 10, which is rotatably connected to the upper end of the rocker arm 13, and a plurality of vacuum suction cups 11 are provided on the lower end surface of the pick-up plate 10. The vacuum suction cups 11 are connected to the vacuum equipment placed outside the cutting device through an air duct, and can grab the display panel on the upper end of the slide 2 by negative pressure suction.

[0036] The specific structure of the flipping mechanism is described below.

[0037] The flipping mechanism includes a gear ring 9 and a bevel gear 12 arranged on one side of the gear ring 9. The gear ring 9 is fixedly connected to the upper end of the second bracket 7. The axis of the gear ring 9 coincides with the axis of the output end of the motor 8. The bevel gear 12 is placed at the connection between the feeding plate 10 and the rocker arm 13. The bevel gear 12 is fixedly connected to the feeding plate 10. The side of the gear ring 9 facing the bevel gear 12 is provided with helical teeth 14, and the helical teeth 14 are meshed with the bevel gear 12.

[0038] The working principle of the flip mechanism is:

[0039] After the motor 8 controls the rocker arm 13 to rotate, the rocker arm 13 will move with the feeding plate 10 and the bevel gear 12. Since the bevel gear 12 is fixed to the feeding plate 10, and the bevel gear 12 is in meshing with the helical teeth 14, when the bevel gear 12 moves, the helical teeth 14 will drive the bevel gear 12 and the feeding plate 10 to rotate by meshing with the bevel gear 12. When the feeding plate 10 moves from above the slide 2 to above the conveyor belt 6, the feeding plate 10 just rotates 180 degrees.

[0040] A better implementation is that a limiting ring 15 is provided inside the gear ring 9, the axis of the limiting ring 15 coincides with the axis of the gear ring 9, the limiting ring 15 is fixedly connected to the upper end of the second bracket 7, and the limiting ring 15 penetrates the rocker arm 13 and is slidably connected to the rocker arm 13. The advantage of this design is that when the rotating bracket controls the rocker arm 13 to rotate, the limiting ring 15 can limit the rocker arm 13 by cooperating with the rocker arm 13, so that the rocker arm 13 will not tilt when rotating.

[0041] Based on the previous embodiment, a further improvement is made, and two support blocks 16 are provided on the limiting ring 15 for supporting the rocker arm 13 after the rocker arm 13 falls, and the support blocks 16 are fixedly connected to the limiting ring 15. When the picking plate 10 falls toward the slide 2 or the conveyor belt 6, the two support blocks 16 on the limiting ring 15 will support the rocker arm 13, reduce the burden of the rotating bracket, and protect the rotating bracket.

[0042] How this application works:

[0043] The display panel to be cut is pre-fixed on the slide 2, and the slide 2 slides along the upper end of the processing seat 1. When the slide 2 moves below the slitting device, the slitting device cuts the display panel.

[0044] When taking materials, the rotating bracket controls the rocker arm 13 to rotate, and the rocker arm 13 presses the vacuum adsorption plate on the upper end of the slide 2 during the rotation, and the vacuum adsorption plate grabs the display panel on the upper end of the slide 2. After the grabbing is completed, the rotating bracket controls the rocker arm 13 to rotate, and the vacuum adsorption plate is sent to the top of the conveyor belt 6.

[0045] During the rotation of the rocker arm 13, the flipping mechanism will control the rotation of the vacuum adsorption plate. When the vacuum adsorption plate is sent to the top of the conveyor belt 6, the display screen on the vacuum adsorption plate will be in an automatic downward state. After stopping the grabbing, the conveyor belt 6 can automatically send out the cut display screen. It can automatically complete the flipping when taking and releasing the material. It has a simple structure, a high degree of integration, and is convenient for personnel to control.
