5. The material clamping position detecting mechanism as claimed in claim 4, wherein the pushing rod comprises a connecting part and a suspending part which are connected into a whole, the connecting part is fixedly connected with the sliding block, and the suspending part is suspended downwards.
6. A conveying system, comprising the material clamping position detecting mechanism according to any one of claims 1 to 5, and further comprising a clamping mechanism, a material conveying line, and at least one packaging line, wherein the packaging line is a first packaging line, the clamping mechanism is located between the first packaging line and the material conveying line, the clamping mechanism clamps the material on the material conveying line and places the material on the first packaging line, and the material clamping position detecting mechanism is arranged at the end of the material conveying line.
7. The transport system of claim 6, wherein the clamping mechanism further comprises an electric pushing cylinder, a pneumatic clamping jaw, and a fixing pin, the pneumatic clamping jaw is disposed on a pushing rod of the electric pushing cylinder, the fixing pin is disposed at an end of the pneumatic clamping jaw, and the fixing pin is used for pushing the optical axis moving assembly to move.
8. A conveyor system as in claim 6 further comprising a weigh platform, a second package line for depositing different weights of material, the weigh platform being disposed at the end of the material transfer line.
9. A material gripping position detection method using the conveying system according to any one of claims 6 to 8, characterized by comprising the steps of:
s1: the clamping mechanism moves towards the material conveying line, and applies force to the optical axis moving assembly to drive the photoelectric switch to move along the first optical axis and the second optical axis;
s2: the photoelectric switch moves forwards, the light of the photoelectric switch is blocked by the material, and the signal of the photoelectric switch is triggered;
s3: the photoelectric switch continues to move forwards, the light of the photoelectric switch is not blocked by the material any more, and the signal of the photoelectric switch is reset to obtain the position of the material;
s4: controlling the clamping mechanism to suck, completing material clamping, and placing the material clamping into a first packaging line;
s5: the clamping mechanism clamps the materials and then returns to the initial position, and the optical axis moving assembly returns to the initial position under the action of gravity to complete the reset action;
s6: if the optical axis moving assembly moves to the limit position, the photoelectric switch is still not triggered, the material is not in the detection range of the photoelectric switch, and due to the fact that a certain included angle exists between the first optical axis and the horizontal plane and between the second optical axis and the horizontal plane, when the optical axis moving assembly moves to the limit position, the optical axis moving assembly returns to the initial position under the action of gravity, and the reset action is automatically completed.
