In this embodiment, the detection device 500 is a correlation photoelectric sensor, and there are 6 correlation photoelectric sensors, and the 6 correlation photoelectric sensors are divided into 3 groups of 2. The first group of correlation photoelectric sensors are used for detecting whether materials fall into the feeding channel, and 2 correlation photoelectric sensors in the first group are respectively positioned at two sides of the material distributing mechanism. The second group of correlation photoelectric sensors are used for detecting whether the materials in the feeding channel are pushed onto the positioning piece, and the 2 correlation photoelectric sensors in the second group are respectively positioned at two sides of the pushing mechanism. The third group of correlation photoelectric sensors is used for detecting whether the material rotates and is positioned, and referring to fig. 16, the connecting lines of the 2 correlation photoelectric sensors in the third group are intersected with the axis of the positioning piece in a horizontal state.

The detection device 500 may be one of an optical fiber type sensor, an electromagnetic type sensor, and a displacement type sensor, and may be used for measuring not only the presence or absence of a material but also data such as a diameter, a color, and a material of the material.

As shown in fig. 14 and 17, the automatic feeding mechanism further includes an air blowing device 600, and the air blowing device 600 is used for blowing air to the material after the material is positioned so that the material rotates on the positioning member, so that the automatic searching center of the material is realized, and the material falls onto a positioning plane at the bottommost part of the positioning member, so as to realize the accurate positioning of the material.

In this embodiment, the air blown out by the blowing device is tangential to the outer circle of the material, so as to ensure that the material rotates on the positioning member.

The blowing device comprises an air pipe 601 with the aperture of 4mm and an electromagnetic valve (not shown in the figure) arranged at one end of the air pipe 601, the air blowing is controlled through the electromagnetic valve, and the air pipe 601 is arranged on a bearing plate of the material distributing mechanism through an upright post 602.

When the material rotates and is positioned, if the material is not clamped to the bottom of the positioning piece or is not clamped into the positioning groove of the positioning piece, the air blowing device is started to blow air, the air blowing device blows air to the material at a high speed along the tangential direction of the outer circle of the material, so that the material rotates until the material is clamped into the positioning groove of the positioning piece or naturally falls to the bottom of the positioning piece by gravity. The compressed air (0.4 MP-0.6 MP) blown by the blowing device can blow off the floating dust on the surface of the material, i.e. has the dust removing function.

The working principle of the automatic feeding mechanism is as follows: manually inserting a hopper into a slot of a material distributing mechanism, opening a valve at the bottom of the hopper, and starting the mechanism; at the moment, the detection device automatically detects whether the material is in place and counts time, the material does not normally fall in place within a set time, the detection device automatically alarms to prompt material clamping, and the whole process is effective when the mechanism operates; the material falls into place within a set time, and at the moment, the pushing mechanism moves backwards to push the single material into the material feeding channel; the pushing mechanism pushes the single material to continuously move backwards until the material is sleeved on the positioning piece, at the moment, the stroke of a first piston rod of a first cylinder of the pushing mechanism just reaches the limit, and the pushing action is finished; after the pushing action is finished, the pushing mechanism moves forwards, at the moment, the detection device starts to detect whether the materials are pushed in place or not, and whether the materials in the hopper fall normally or not, if any faults occur, the alarm is given in time and the machine is stopped; after the detection device detects and outputs a normal signal, the second cylinder of the rotating mechanism starts to work, the material is slowly erected, and then the blowing device starts to work; the air blowing device blows compressed air at an angle of 30 degrees for 30 seconds, compressed air flow impacts on an outer circular cutting line of the material, so that the material rotates on the positioning piece, and the automatic searching of the center of the material and the falling of the material onto a positioning plane at the bottommost part of the positioning piece are realized; at the moment, the material is accurately positioned after dust removal and overturning positioning, and after the air blowing device blows air for 30 seconds, a material preparation completion signal is sent out to the outside, and other equipment is waited to take the material; when other equipment takes the material, the mechanism receives a material taking completion signal, at the moment, the rotating mechanism resets, the counter is increased by 1, and a next cycle starting signal is sent. When the counter reaches the work count number set by staff (the set value is about five less than the number of the materials actually carried by the hopper), the mechanism can send out prompt alarm to prompt the staff to replace the hopper; when changing the hopper, the staff needs to close the valve on the hopper (2 to 3 materials possibly exist in the hopper at the moment), pull out the empty hopper, insert a new hopper into the distributing mechanism, open the valve on the hopper, press the start button to clear the counter for accumulated counting, and the mechanism continues to start working at present. At the moment, uninterrupted feeding is completed, and the empty hopper can be used again after backfilling.

The invention also comprises a control system which is connected with the control rotating mechanism and the pushing mechanism and is used for controlling the rotating mechanism and the pushing mechanism.

The automatic feeding mechanism improves the production efficiency, and solves the problems of low development speed, high cost and high development technical difficulty of automatic feeding equipment in mass production.
