Generally, the size of an object is used as a judgment standard, 7 inches are used as a boundary, when the size of the object shot by an industrial vision camera is smaller than 7 inches, the waste mobile phone is judged, and the mechanical arm 2 transfers the waste mobile phone from the first-stage conveyor belt 1 to the first second-stage conveyor belt 11A. When the size of the object shot by the industrial vision camera is larger than 7 inches, the object is judged to be a waste tablet personal computer, and the mechanical arm 2 transfers the waste mobile phone from the primary conveyor belt 1 to the second secondary conveyor belt 11B. An automatic labeling machine 3 is further arranged at the rear end of the conveyor belt 1, in the embodiment, an EP301 full-automatic single-side corner labeling machine can be adopted to label the electronic equipment which is still left on the primary conveyor belt 1 and is not clamped by the mechanical arm 2 for various reasons (such as serious damage and the like), and the electronic equipment is collected and handed to a human for processing.
In this embodiment, there is first transport conveyer belt 12A at the end connection of first secondary conveyer belt 11A, and on the old and useless cell-phone on the first secondary conveyer belt 11A transported third secondary conveyer belt 13A through first transport conveyer belt 12A, third secondary conveyer belt 13A was transparent conveyer belt to subsequent operation of shooing. Similarly, a second transfer conveyor belt 12B is connected to the end of the second secondary conveyor belt 11B, the waste flat computers on the second secondary conveyor belt 11B are transferred onto a fourth secondary conveyor belt 13B through the second transfer conveyor belt 12B, and the fourth secondary conveyor belt 13B is also a transparent conveyor belt.
Step S2, the mechanical tiling machine 4 is arranged on each of the third secondary conveyor belt 13A and the fourth secondary conveyor belt 13B to adjust the position of the waste mobile phone or the tablet computer on the conveyor belts.
Referring to fig. 3, the mechanical tiling machine 4 includes a height-limiting shaft 41, a clamping plate 42, a linear displacement device (not shown) and a rotating device 43, the third secondary conveyor belt 13A or the fourth secondary conveyor belt 13B passes through the mechanical tiling machine 4, and the height-limiting shaft 41 is disposed at a suitable height above the conveyor belts, so that the gap between the height-limiting shaft 41 and the conveyor belts can only allow one mobile phone or tablet computer to pass horizontally. If the mobile phones or the tablet computers are stacked together, the mobile phones or the tablet computers are obstructed by the height limiting shaft 41, and only the lowest mobile phone or the tablet computer can pass through the height limiting shaft 41, while the lowest mobile phone or the tablet computer is obstructed to fall down, so that the mobile phones or the tablet computers sequentially pass through the height limiting shaft 41. Since the thickness of the existing smart phone or tablet computer is generally 7-9mm, the gap between the height limiting shaft 41 and the conveyor belt is preferably 11-13 mm.
The height-limiting shaft 41 is preferably further connected with a rotating device 43, such as a motor, the rotating device 43 can be directly connected with the height-limiting shaft 41, or can be connected with the height-limiting shaft 41 through a necessary transmission structure to drive the height-limiting shaft 41 to rotate, the rotating direction is opposite to the transmission direction of the lower conveyor belt, and the stacked mobile phones or tablet computers are pushed backwards to fall down more smoothly, so that the mobile phones or tablet computers pass through the height-limiting shaft 41 one by one.

The linear displacement device can adopt an air cylinder, an electric cylinder, a gear rack mechanism and the like, and clamps the waste mobile phone on the third secondary conveyor belt 13A or the waste tablet computer on the fourth secondary conveyor belt 13B through the relative movement of the two clamping plates 42, and pushes the waste mobile phone or the waste tablet computer to the center of the conveyor belt. The symmetry axis of the waste mobile phone or the tablet computer after being processed by the clamping plate 42 is coincident with the symmetry axis of the conveyor belt along the vertical direction.
Because the sizes of different waste mobile phones or tablet computers are not identical, in order to avoid the clamping plates 42 from damaging the mobile phones or the tablet computers, the opposite sides of the two clamping plates 42 are provided with pressure sensors, and when the pressure sensors detect that the pressure reaches a preset threshold value, the linear displacement device is controlled to move reversely, and the clamping plates 42 are controlled to be loosened. Preferably, a photoelectric sensor is further disposed on a side of the clamping plate 42 facing the height-limiting shaft 41, and when a mobile phone or a tablet computer approaches, the photoelectric sensor detects that the linear displacement device is controlled to drive the clamping plate 42 to move towards each other, so as to prepare for starting to adjust the movement of the mobile phone or the tablet computer.
