For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Embodiment 1

[0042] See also Figures 1 to 7As shown, the first embodiment of the present invention provides a feeding device including a plate material segmentation section 100, a plate material placement section 200 and a plate material clamping section 300; the plate material segmentation section 100 includes a material storage mechanism and a material positioning mechanism; the material storage mechanism stores stacked plate materials, and the plate materials include but are not limited to mobile phone cover glass 600, and the plate materials can also be other plate or sheet products that need to be processed. The material storage mechanism has a storage function, and can also push a single plate material or multiple plate materials connected together to the material positioning mechanism. It should be noted that multiple plate materials connected together refer to multiple plate materials that are artificially connected together. The material positioning mechanism can position the plate-like material received from the material storage mechanism, that is, adjust the position of the plate-like material on the material positioning mechanism to facilitate the adsorption of the plate-like material picking and placing part 200, and avoid damage to the plate-like material by the plate-like material picking and placing part 200; when the plate-like materials are stacked together, when the plane of the plate-like materials is relatively smooth, the two contacting plate-like materials are easy to stick together. If the plate-like material picking and placing part 200 is directly used to pick and place the plate-like materials, it is very easy to absorb two or even more plate-like materials. During the transfer process, the plate-like materials may fall and cause damage to the plate-like materials. In addition, inserting multiple plate-like materials into the material rack 500 may not meet the insertion requirements. The plate-like material taking and placing part 200 is used to absorb the plate-like material after the position is adjusted from the material positioning mechanism, and then flip the taken plate-like material to a certain angle, such as flipping the plate-like material 90°, so that the plane of the plate-like material changes from a horizontal state to a vertical state; the flipping angle of the plate-like material by the plate-like material taking and placing part 200 can be determined according to the implementation situation, such as according to the angle of the insertion position of the material rack 500 placed at the plate-like material clamping part 300; after the plate-like material taking and placing part 200 flips the plate-like material to a set angle, the plate-like material is inserted into the insertion position of the material rack 500 at the plate-like material clamping part 300, and the plate-like material is released, that is, the plate-like material is no longer adsorbed. When the material rack 500 of the plate-like material taking and placing part 200 is full of plate-like materials, the material rack 500 can be removed and installed on the CNC. It should be noted that in this embodiment, the material storage mechanism pushes a single piece of plate-like material to the material positioning mechanism as an example.

[0043] The loading equipment provided by this embodiment, when in use, the plate-like materials are stacked at the material storage mechanism, and the material storage mechanism can push a single piece of plate-like material to the material positioning mechanism, and the material positioning mechanism positions the received plate-like materials to ensure the accuracy of the plate-like material picking and placing part 200 in picking and placing the materials; and the material picking and placing part adsorbs the plate-like materials positioned at the material positioning mechanism, and flips the plate-like materials to meet the angle on the material rack 500 (that is, the upper and lower material racks 500 of the CNC) inserted at the plate-like material clamping part 300, so that when the material rack 500 is full, the material rack 500 is removed from the plate-like material clamping part 300 and installed on the CNC, thereby realizing the rapid and automatic insertion of plate-like materials, saving time, reducing manpower, and the operator is not prone to work fatigue.

[0044] In an optional solution of this embodiment, the material storage mechanism includes a loading platform 101 and a material pulling device 102. The loading platform 101 is used to place plate-like materials, and the material pulling device 102 is used to move the plate-like materials on the loading platform 101 in parallel and translate the plate-like materials to the material positioning mechanism. The loading platform, the material pulling device and the material positioning mechanism are arranged side by side, and the loading platform is located between the material pulling device and the material positioning mechanism.

[0045] Specifically, the loading platform 101 can carry multiple plate-like materials of the same size and shape stacked together; the loading platform 101 is a plate-like structure. The material pulling device 102 pushes the single plate-like material on the loading platform 101 to move along the second direction; in this embodiment, the material pulling device 102 can be a screw stepper motor. A push block 106 is installed on the material pulling device 102, and the edge of the plate-like material is pushed by the push block 106 to move it, so that the plate-like material can be translated. It should be noted that the material pulling device 102 can also be an electric cylinder, a cylinder or a hydraulic cylinder.

[0046] In an optional scheme of this embodiment, the plate-like material slicing part 100 also includes a slicing part support platform 103, and a material storage mechanism and a material positioning mechanism are installed on the slicing part support platform; the material storage mechanism also includes a second XY-axis fine-tuning platform 104 and a first linear slide 105, the second XY-axis fine-tuning platform 104 is installed on the slicing part support platform, and the first linear slide 105 is installed on the table of the second XY-axis fine-tuning platform 104, wherein the slider of the first linear slide 105 is fixedly connected to the table of the second XY-axis fine-tuning platform 104, the pulling device 102 is installed on the table of the second XY-axis fine-tuning platform 104, and the push block 106 is fixedly connected to the guide rail of the first linear slide 105, and the guide rail of the first linear slide 105 can guide the push block 106, thereby improving the accuracy of the translation of the plate-like material. In order to determine the initial position and the limit position when the material pulling device 102 moves the push block 106, the two ends of the guide rail of the first linear slide 105 are respectively installed with limit sensors 107. After the material pulling device 102 moves from the initial position, when the pusher contacts the edge of the plate-like material, the pusher starts to push the plate-like material to move horizontally. When the pusher moves to the limit position, the limit sensor 107 at the limit position stops the forward movement of the material pulling device 102 and starts the backward movement of the material pulling device 102 to return to the initial position. When the pusher moves to the initial position, the limit sensor 107 at the initial position stops the backward movement of the material pulling device 102 and waits for or starts the next material pushing movement. It should be noted that the position of the limit sensors 107 at both ends of the guide rail of the first linear slide 105 on the guide rail can be adjusted. The second XY axis fine-tuning platform 104 is used to fine-tune the position of the material pulling device 102. The guiding direction of the first linear slide 105 is parallel to the second direction.

[0047] In the optional solution of this embodiment, the material storage mechanism also includes a second linear slide 108, and the second XY axis fine-tuning platform 104 is fixedly connected to the slider of the second linear slide 108 through the first bottom plate. In this way, by adjusting the position of the second XY axis fine-tuning platform 104 and the material pulling device 102, the first bottom plate and the slice support platform can be detachably connected through the angle plate 109, which is convenient for fixing the position of the second XY axis fine-tuning platform, so as to facilitate the plate-like materials of different sizes carried by the loading platform 101. In other words, when the size of the plate-like materials carried on the loading platform 101 is small, the position of the second XY axis fine-tuning platform 104 and the material pulling device 102 can be made closer to the loading platform 101. It should be noted that the slider of the second linear slide can be driven by a telescopic device, such as a cylinder, a hydraulic cylinder, an electric cylinder or a screw motor; a Z axis fine-tuning platform 121 can also be installed on the table of the second XY axis fine-tuning platform 104 to adjust the height of the material pulling device 102.

[0048] In an optional solution of this embodiment, in order to adapt the position of the second XY-axis fine-tuning platform 104 and the pulling device 102 to be close to the loading platform 101 and to facilitate the loading platform 101 to carry plate materials of different sizes, a first notch 110 is opened on one side of the loading platform 101 close to the second XY-axis fine-tuning platform 104.

[0049] In an optional solution of this embodiment, the material storage mechanism further includes a lifting device 111 disposed below the loading platform, for raising or lowering the loading platform 101 .

[0050] Specifically, the lifting device 111 may be a screw stepping motor, and the screw of the screw stepping motor is fixedly connected to the loading platform 101. It should be noted that the lifting device 111 may also be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder.

[0051] In the optional scheme of this embodiment, the lifting device 111 is installed below the support platform of the slicing part; the material storage mechanism also includes a third linear slide 112, the slider of the third linear slide 112 is fixedly connected to the bottom of the support platform of the slicing part, and the guide rail of the third linear slide 112 can guide the lifting and lowering movement of the loading platform 101, thereby improving the lifting and lowering stability of the loading platform 101. In order to determine the limit position when the lifting device 111 lifts the loading platform 101, a limit sensor 107 is installed at the end of the guide rail of the third linear slide 112. When the material pulling device 102 conveys a piece of plate-like material to the material positioning mechanism and the material pulling device 102 returns to the initial position, the lifting device 111 causes the loading platform 101 to rise to a set height, even if the thickness of a sheet material grows on the loading platform 101, so as to facilitate the normal material pulling of the material pulling device 102 next time. It should be noted that the position of the limit sensor 107 at the end of the guide rail of the third linear slide 112 on the guide rail can be adjusted.

[0052] In an optional solution of this embodiment, the material storage mechanism further includes a size adjustment device arranged on the side of the loading platform, which is used to limit the plate-like materials of different sizes carried on the loading platform 101.

[0053] Specifically, the size adjustment device includes a fourth linear slide 114 and two columns 115. The two columns 115 are respectively fixed on two different sliders of the fourth linear slide 114. The fourth linear slide 114 is fixed on the slice support platform. The slider of the fourth linear slide 114 and the slice support platform can be detachably connected through an angle plate 109, which is convenient for fixing the position of the slider, so as to facilitate the plate-like materials of different sizes carried by the loading platform 101. That is to say, when the size of the plate-like materials carried on the loading platform 101 is small, the two sliders of the fourth linear slide 114 can be moved toward each other, that is, the distance between the two sliders is reduced. In order to adapt to the distance between the two sliders of the fourth linear slide 114 to be reduced to a set distance, so as to facilitate the plate-like materials of different sizes carried by the loading platform 101, the second notch 116 is opened on the opposite sides of the loading platform 101. The side where the second notch 116 is located is adjacent to the side where the first notch 110 is located. It should be noted that the slider of the fourth linear slide can be pushed by a telescopic device, such as a cylinder, a hydraulic cylinder, an electric cylinder or a screw motor.

[0054] In an optional solution of this embodiment, a position sensor 117 is installed on the column 115 of the size adjustment device. When the lifting device 111 drives the loading platform 101 and the stack of sheet materials carried to rise to the position sensor 117, the material removal device 102 moves the push block 106 to push the top sheet material of the stack of sheet materials to the material positioning mechanism. The position sensor 117 can be a proximity switch or a photoelectric switch.

[0055] In an optional scheme of this embodiment, the material positioning mechanism includes a positioning fixture platform 118, which is used to carry the plate-like material transported by the pulling device 102; the lower surface of the plate-like material on the loading platform can be parallel to the table surface of the positioning fixture platform, that is, after the jacking device raises the loading platform, the lower surface of the plate-like material on the top layer is parallel to the table surface of the positioning fixture platform, which is conducive to the realization of the flat pushing of the plate-like material by the pulling device.

[0056] Specifically, two adjacent sides of the positioning fixture platform 118 are provided with stoppers 119 for realizing position alignment of the plate-like material.

[0057] In the optional solution of this embodiment, the material positioning mechanism also includes a positioning cylinder, a first XY-axis fine-tuning platform 120 and a Z-axis fine-tuning platform 121.

The first direction is also parallel to the telescopic direction of the positioning cylinder.

[0058] Specifically, the Z-axis fine-tuning platform 121 is installed on the table of the first XY-axis fine-tuning platform 120, the positioning fixture platform 118 is installed on the table of the Z-axis fine-tuning platform 121, and the positioning cylinder is installed on the table of the Z-axis fine-tuning platform 121. The first XY-axis fine-tuning platform 120 is installed on the slice support platform.

[0059] The directions of the X-axis and Y-axis of the second XY-axis fine-tuning platform 104 can be respectively the same as the directions of the X-axis and Y-axis of the first XY-axis fine-tuning platform 120. The first XY-axis fine-tuning platform 120, the second XY-axis fine-tuning platform 104, and the Z-axis fine-tuning platform 121 can realize precise adjustment of the position of the sheet material on the positioning fixture platform 118. A positioning block 122 is installed on the piston rod of the positioning cylinder, and a waist-shaped hole 123 is provided on the fixed clamping block to adjust the position of the positioning block 122 to face sheet materials of different sizes. In order to adapt the positioning block 122 to the positioning of sheet materials of different sizes, a positioning groove 124 matching the positioning block 122 is provided on the positioning fixture platform 118. It should be noted that the first XY-axis fine-tuning platform 120, the second XY-axis fine-tuning platform 104, and the Z-axis fine-tuning platform 121 are all prior art and their specific structures are not described here.

The positioning cylinder can also be replaced by a hydraulic cylinder, an electric cylinder, or a screw motor to achieve positioning accuracy.

It should be noted that the parallel robot 201 can realize free movement in three directions of the X-axis, the Y-axis, and the Z-axis. In addition, the parallel robot 201 can be a parallel robot 201 with four degrees of freedom.
