DETAILED DESCRIPTION

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figures 1-4 As shown, a micro-automatic loading and unloading device based on PLC electrical control includes: a detection frame 1, on the surface of which is an automatic loading and unloading mechanism 2; an anti-deviation mechanism 3, which includes a stop block 31 on the top of the automatic loading and unloading mechanism 2, two limit blocks 32 on the top of the automatic loading and unloading mechanism 2, two pulleys 33 rotatably connected to the surface of the limit blocks 32, and a ring of buffer blocks 34 fixedly connected to the surface of the pulleys 33, a connecting frame 311 fixedly connected to the end of the limit blocks 32, an electric push rod 37 on the surface of the automatic loading and unloading mechanism 2, an adjusting block 38 fixedly connected to the telescopic end of the electric push rod 37, and the end of the connecting frame 311 contacting the surface of the adjusting block 38.

[0024] One of the conveyor frames 21 has a material tray frame fixedly connected to its top, and the material tray frame has a propulsion cylinder at both the front and rear ends.

[0025] like Figures 2-3 As shown, the automatic loading and unloading mechanism 2 includes two conveyor frames 21 fixedly connected to one side of the detection frame 1. Two pulleys 24 are rotatably connected to the inner wall of the conveyor frame 21. A conveyor belt 25 is connected to the surface of the two pulleys 24.

[0030] As shown in Figure 3 , the surface of one of the conveying frames 21 is fixedly connected with two fixed frames 39. The surface of the connecting frame 311 is slidingly connected to the inner wall of the fixed frame 39. The surface of the connecting frame 311 is fixedly connected with two springs 310 at the lower end. The other end of the spring 310 is fixedly connected to the lower end of the fixed frame 39.

[0031] The utility model discloses in using, according to preset program, operating PLC electrical device 22, automatic opening propelling air cylinder, servo motor 26 and electric push rod 37, the telescopic end of electric push rod 37 removes and drives adjusting block 38 to remove, and adjusting block 38 removes and pushes two connecting frames 311 to move close to each other, and connecting frame 311 removes and drives limit block 32 and positioning frame 36 to remove, and after positioning frame 36 removes and contacts optical lens, automatic closing electric push rod 37, propelling air cylinder operation makes one optical lens in the inside of material disc frame fall to one conveyor belt 25, and the optical lens that falls contacts the surface of buffer block 34, and then reduces the speed of optical lens falling, makes optical lens steady fall in conveyor belt 25, and the conveyor belt 25 of transmission drives optical lens to convey, and the optical lens that conveys contacts two groups of ball bearings 35, and makes optical lens accurate delivery to detection frame 1.
