Technical Field

[0002] Flake materials refer to materials to be processed that are in the shape of thin sheets. They are common materials in the field of production and processing. When feeding, flake materials are often stacked together, and the surface of each flake material is bonded with a corresponding protective film. By bonding the protective film, the flake material can be prevented from damage and contamination.

[0003] In the related art, sheet materials are generally fed through a material box and a robot. There are multiple layers of sheet materials stacked on the material box. Each time the robot takes away a layer of sheet materials on the material box, the material box rises to a certain height to cooperate with the robot to clamp the next layer of sheet materials.

[0026] The X-axis suction assembly 20 includes an X-axis suction cup 21, an X-axis lifting member 22, and an X-axis translation member 23.

Through the mutual cooperation of the X-axis suction cup 21, the X-axis lifting member 22 and the X-axis translation member 23, the X-axis material suction assembly 20 can conveniently suck and place the sheet material.

[0028] The Y-axis suction assembly 40 includes a Y-axis suction cup 41, a Y-axis lifting member 42, and a Y-axis translation member 43. The Y-axis suction cup 41 is connected to the Y-axis lifting member 42, and the Y-axis lifting member 42 is connected to the Y-axis translation member 43.

[0029] When the Y-axis suction assembly 40 needs to suck the sheet material from the vacuum adsorption platform 30, the Y-axis suction cup 41 and the Y-axis lifting component 42 are first translated to the top of the vacuum adsorption platform 30 by the Y-axis translation component 43, and then the Y-axis suction cup 41 is lowered to a height suitable for sucking the sheet material by the Y-axis lifting component 42, and then the sheet material on the vacuum adsorption platform 30 is sucked by the Y-axis suction cup 41; then the Y-axis lifting component 42 is used to raise the Y-axis suction cup 41 sucking the sheet material to the height before the lowering; then the Y-axis translation component 43 is used to raise the Y-axis suction cup 41 sucking the sheet material 1 and the Y-axis lifting member 42 are translated to the top of the conveyor belt 60; then the Y-axis suction cup 41 with the sheet material sucked is lowered to a height suitable for placing the sheet material by the Y-axis lifting member 42, and then the sucked sheet material is placed on the conveyor belt 60 by the Y-axis suction cup 41; then the Y-axis lifting member 42 is used to raise the Y-axis suction cup 41 with the sheet material placed to the height before the lowering; finally, the Y-axis suction cup 41 with the sheet material placed and the Y-axis lifting member 42 are translated again to the top of the vacuum adsorption platform 30 by the Y-axis translation member 43, ready for the next suction of the sheet material. Through the mutual cooperation of the Y-axis suction cup 41, the Y-axis lifting member 42 and the Y-axis translation member 43, the Y-axis material suction assembly 40 can conveniently suck and place the sheet material.

[0030] The lifting material box 10 includes a material discharging platform 11, a lifting motor 12 and a lifting guide rail 13. The lifting motor 12 is connected to the material discharging platform 11 in a transmission manner, and is used to drive the material discharging platform 11 to lift; the lifting guide rail 13 is connected to the material discharging platform 11 in a sliding manner, and is used to limit the material discharging platform 11.

[0031] The discharge platform 11 is used to place multiple layers of sheet materials. In order to cooperate with the X-axis suction component 20 to suck the sheet materials from the discharge platform 11, the lifting motor 12 can adjust the height of the discharge platform 11 in real time, and limit the discharge platform 11 through the lifting guide rail 13, so that the height adjustment process of the discharge platform 11 is smoother.

[0032] The vacuum adsorption platform 30 includes a vacuum adsorption plate 31, and a plurality of vacuum adsorption holes 32 are provided on the vacuum adsorption plate 31. The vacuum adsorption holes 32 are connected to the air inlet of the vacuum generator through the internal vacuum cavity of the vacuum adsorption plate 31, so that the surface of the vacuum adsorption holes 31 is in a vacuum negative pressure state.

[0033] Through the mutual cooperation of the vacuum adsorption plate 31 and the vacuum adsorption hole 32, the vacuum adsorption platform 30 can position the sheet material placed thereon, prevent the sheet material placed thereon from being taken away by the X-axis material adsorption component 20, and prevent the sheet material from moving before being adsorbed by the Y-axis material adsorption component 40.

[0034] The film tearing assembly 50 includes a film tearing support plate 51, a film tearing pressing plate 52, a film clamping cylinder 53 and a film tearing cylinder 54.

The film tearing cylinder 54 is connected to the film tearing support plate 51 and the film tearing pressing plate 52 respectively, and the film tearing cylinder 54 is used to drive the film tearing pressing plate 52 and the film tearing support plate 51 to move downward when one end of the protective film is clamped between the film tearing pressing plate 52 and the film tearing support plate 51, so as to tear off the protective film of the sheet material.

[0035] Through the mutual cooperation of the film tearing support plate 51, the film tearing pressure plate 52, the film clamping cylinder 53 and the film tearing cylinder 54, when the sheet material sucked by the Y-axis suction assembly 40 passes directly above the film tearing assembly 50, the protective film on the lower surface of the sheet material is clamped by the film tearing assembly 50. As the sheet material continues to be translated by the Y-axis suction assembly, the protective film on the lower surface of the sheet material is separated from the sheet material body, thereby preparing for further assembly and processing of the sheet material.

[0036] The sheet material feeder further includes an upper blowing assembly, a lower blowing assembly and a protective film collecting device. The upper blowing assembly is installed between the film tearing support plate 51 and the vacuum adsorption platform 30, and the lower blowing assembly is installed above the film tearing assembly 50.

The upper blowing assembly is used to blow the protective film upward to prevent the protective film from being adsorbed by the vacuum adsorption platform 30; the lower blowing assembly is used to blow the protective film downward to make the torn protective film fall downward; the protective film collecting device is used to collect the torn protective film. By setting the upper blowing assembly, the film tearing assembly 50 can avoid the interference of the vacuum adsorption platform 30 in the process of tearing off the protective film; by setting the lower blowing assembly, when the protective film on the lower surface of the sheet material is separated from the sheet material body, the protective film can be blown to the protective film collecting device by the airflow from top to bottom, so as to facilitate the collection of the protective film.

[0038] Through the cooperation between the first lifting material box and the first X-axis material suction assembly, and the cooperation between the second lifting material box and the second X-axis material suction assembly, the first X-axis material suction assembly and the second X-axis material suction assembly can alternately place sheet materials on the vacuum adsorption platform 30, thereby greatly improving the working efficiency of the sheet material feeder.

[0039] Furthermore, the sheet material feeder further comprises a gantry, which is arranged along the X-axis direction, and the first X-axis material suction assembly and the second X-axis material suction assembly are respectively slidably connected to the gantry. The first X-axis material suction assembly and the second X-axis material suction assembly are respectively slidably connected to the gantry, so that the first X-axis material suction assembly can freely translate directly above the first lifting material box and directly above the vacuum adsorption platform 30, and the second X-axis material suction assembly can freely translate directly above the second lifting material box and directly above the vacuum adsorption platform 30.

[0041] Wherein, the working method of the sheet material feeder includes: The X-axis suction assembly 20 sucks the sheet material from the lifting material box 10; the lifting material box 10 descends to make way for the shaking operation of the X-axis suction assembly 20; the X-axis suction assembly 20 performs a shaking operation to prevent sucking multiple layers of sheet material at the same time; after the shaking operation is completed, the lifting material box 10 rises; the X-axis suction assembly 20 places the sucked sheet material on the vacuum adsorption platform 30 along the X-axis direction; the Y-axis suction assembly 40 sucks the sheet material from the vacuum adsorption platform 30; the Y-axis suction assembly 40 moves the sucked sheet material along the Y-axis direction; when the sheet material moves to above the film tearing assembly 50, the film tearing assembly 50 clamps the protective film and descends to separate the sheet material from the protective film; when the sheet material moves to above the conveyor belt 60, the Y-axis suction assembly 40 places the sheet material on the conveyor belt 60; the conveyor belt 60 conveys the sheet material to the assembly station for product assembly.

[0042] In the working method of the above-mentioned sheet material feeder, the X-axis material suction component first sucks the sheet material from the lifting material box, and then the lifting material box descends to make way for the shaking operation of the X-axis material suction component; then, the X-axis material suction component performs a shaking operation to prevent multiple layers of sheet material from being sucked up at the same time; after the shaking operation is completed, the lifting material box rises to prepare for the next time the X-axis material suction component sucks up the sheet material; then, the X-axis material suction component places the sucked sheet material on the vacuum adsorption platform along the X-axis direction, and the Y-axis material suction component sucks the sheet material from the vacuum adsorption platform and moves the sucked sheet material along the Y-axis direction; when the sheet material moves to above the film tearing component, the film tearing component clamps the protective film and descends to separate the sheet material from the protective film; when the sheet material moves to above the conveyor belt, the Y-axis material suction component places the sheet material on the conveyor belt, and the conveyor belt conveys the sheet material to the assembly station. It can be seen that through the mutual cooperation of the lifting material box, X-axis material suction assembly, vacuum adsorption platform, Y-axis material suction assembly, film tearing assembly and conveyor belt, the sheet material feeder can avoid multiple layers of sheet materials from sticking together, thereby improving the film tearing quality of the sheet material.
