[0042] Embodiment 2

[0043] Please refer to Figure 5 As shown, a connecting shaft 301 is fixedly connected to the middle axis of each of the transmission gears 3. The connecting shafts 301 are respectively rotatably installed inside a corresponding set of mounting holes 212. Both of the transmission gears 3 are meshed with a plurality of tooth grooves 231. One end of the extension plate 31 close to the feeding belt and away from the transmission gear 3 is fixedly connected with a connecting cylinder 33. A transmission thread 331 is provided on the inner wall of the connecting cylinder 33. A bottom of one side of the extension plate 31 close to the feeding belt and away from the transmission gear 3 is fixedly installed with an electric telescopic rod 34. A connecting seat 341 is rotatably installed on the output end of the electric telescopic rod 34.

[0044] A square groove 401 with an upward opening is provided inside the rotating seat 4. Two rotating rods 41 are symmetrically and rotatably installed at both ends of the square groove 401. Both ends of the rotating rods 41 penetrate through the side wall of the rotating seat 4 and are symmetrically fixedly connected with a pair of connecting rods 411. One end of the pair of connecting rods 411 away from the rotating rods 41 is fixedly installed with a cylindrical pressing seat 412;

[0045] When the electric telescopic rod 34 contracts, it pulls the cross plate 45 to move. Since the small gear 42 is meshed with the rack 451, it can drive the rotating rods 41 on both sides to rotate, and the cylindrical pressing seats 412 installed on the connecting rods 411 tilt up until the two cylindrical pressing seats 412 are respectively in close contact with the opposite inner walls of the refrigerator drawer, facilitating the tightening and fixing of the refrigerator drawer and increasing the stability during the transportation of the refrigerator.

[0046] Embodiment 3

[0047] Please refer to Figures 6-7As shown, small gears 42 are fixedly installed in the middle of the rotating rod 41. The middle of the lower surface of the rotating seat 4 is fixedly connected with a connecting sleeve 43. The rotating seat 4 is rotatably installed on the connecting cylinder 33 through the connecting sleeve 43. A circular hole 44 is opened in the middle of the lower surface of the rotating seat 4. A transverse plate 45 is arranged inside the rotating seat 4. The transverse plate 45 is located at the bottom of the two small gears 42. A rack 451 is fixedly connected to both ends of the transverse plate 45. The two small gears 42 are located between the two racks 451. The racks 451 are respectively meshed with a small gear 42 close to them. The two racks 451 are slidably arranged between the inner walls of both sides of the square groove 401. A square hole 452 is opened in the middle of the upper surface of the transverse plate 45. A square rod 453 is slidably arranged inside the square hole 452. The top of the square rod 453 is fixedly connected with a pressing disc 454. A spring 455 is arranged between the bottom of the square rod 453 and the inner wall of the bottom of the square hole 452;

[0048] When the electric telescopic rod 34 extends, the transverse plate 45 moves towards the opening of the square groove 401, and the pressing disc 454 moves synchronously. It will first contact the inner wall of the refrigerator drawer. After that, the spring 455 is compressed, which is convenient for pressing the refrigerator drawer against the pneumatic suction cup 32 before the cylindrical pressing seat 412 moves in the reverse direction and disengages from the inner wall of the refrigerator drawer, so as to facilitate the pneumatic suction cup 32 to fix the refrigerator drawer.

[0049] The center of the lower surface of the transverse plate 45 is fixedly connected with a cylindrical seat 46. The cylindrical seat 46 is slidably arranged inside the circular hole 44. An annular groove 461 is opened in the middle of the cylindrical seat 46. A plurality of grooves 462 are evenly opened on the side wall of the annular groove 461.

[0050] A threaded cylinder 47 is rotatably installed on the annular groove 461. The threaded cylinder 47 is arranged inside the connecting cylinder 33 and is in threaded connection with the transmission thread 331. The bottom of the threaded cylinder 47 is fixedly installed on the connecting seat 341. A cylindrical friction part 48 is installed inside each of the grooves 462.

[0051] During use, the refrigerator drawer to be detected is placed with its opening facing down on the two conveyor belts 17 at the bottom of the gantry 131, that is, a pair of feeding belts. The motor 151 works to drive the rotating shaft 16 and the first pulley 161 to rotate, and the conveyor belt 17 rotates synchronously, so as to drive the refrigerator drawer to move and convey it. In addition, by controlling the motor 151 to work intermittently, the conveyor belt 17 is driven to rotate intermittently to transport the refrigerator drawer;

[0052] When the refrigerator drawer is transported to the bottom of the first detection device 14 by the conveyor belt 17, the first detection device 14 can detect the bottom detection surface of the refrigerator drawer, and then it is transported to the end of the feeding belt by the conveyor belt 17, and the conveyor belt 17 stops moving;

[0053] After that, the electric telescopic rod 34 contracts, pulling the threaded cylinder 47 downward. Since the threaded cylinder 47 is installed inside the annular groove 461, the cross plate 45 and the cylindrical seat 46 move synchronously. The rack 451 moves towards the bottom of the square groove 401. Since the small gear 42 is meshed with the rack 451, the rotating rods 41 on both sides can be driven to rotate. The cylindrical pressing seats 412 installed on the connecting rods 411 tilt up until the two cylindrical pressing seats 412 are respectively in close contact with the opposite inner walls of the refrigerator drawer, and then the refrigerator drawer can be tightened and fixed;

[0054] In addition, both the connecting rod 411 and the cylindrical pressing seat 412 are elastic. On the one hand, it can prevent the rotating rod 41 from rotating excessively and bursting and deforming the refrigerator drawer. On the other hand, according to the different sizes of the refrigerator drawer, using the elasticity of the connecting rod 411 to deform, the two cylindrical pressing seats 412 can lift the refrigerator drawer, increasing the applicable range of the device;

[0055] After that, the hydraulic telescopic rod 24 works, driving the sliding rod 23 downward. Through the meshing of the transmission gear 3 with the tooth groove 231, the two transmission gears 3 can be driven to rotate. The transmission gear 3 close to the feeding belt rotates clockwise, and the transmission gear 3 close to the discharging belt rotates counterclockwise. The rotating seat 4 at the end of the extension plate 31 is lifted until the extension plate 31 is in a vertical state;

[0056] At this time, the pneumatic suction cup 32 works to adsorb the refrigerator drawer on the suction cup of the pneumatic suction cup 32, and the second detection device 121 can detect the side wall of the refrigerator drawer;

[0057] After that, the electric telescopic rod 34 extends, the cross plate 45 moves towards the opening of the square groove 401, the pressing disc 454 moves synchronously and tightly presses on the inner wall of the refrigerator drawer, the spring 455 is compressed, and at the same time the cylindrical pressing seat 412 moves in the opposite direction and disengages from the inner wall of the refrigerator drawer;

[0058] During this process, the threaded cylinder 47 and the cylindrical friction member 48 are threadedly installed inside the connecting cylinder 33. When the electric telescopic rod 34 contracts and pulls the cross plate 45 downward, the threaded cylinder 47 rotates clockwise. Since the friction cylindrical friction member 48 is pushed into the deepest part of the groove 462 and does not contact the inner wall of the threaded cylinder 47, the threaded cylinder 47 can rotate smoothly and the cross plate 45 does not rotate. When the electric telescopic rod 34 extends and pushes the cross plate upward, the threaded cylinder 47 rotates counterclockwise. Since the friction cylindrical friction member 48 is pushed into the shallowest part of the groove 462 and is in close contact with the inner wall of the threaded cylinder 47, it is clamped. At this time, the rotation of the threaded cylinder 47 inside the connecting cylinder 33 can drive the cross plate 45 and the rotating seat 4 to rotate as a whole, and the refrigerator drawer clamped between the pressure plate 454 and the pneumatic suction cup 32 can rotate synchronously, so as to realize the flipping of the refrigerator drawer, which is convenient for the second detection device 121 to detect each side wall of the refrigerator drawer, solving the problems of low detection efficiency by manual inspection and the occurrence of misdetection;

[0059] After the detection is completed, the hydraulic telescopic rod 24 extends, driving the two transmission gears 3 to rotate in the reverse direction, so that the flipping auxiliary assembly can be reset. When the pneumatic suction cup 32 is reset, the refrigerator drawer can be smoothly placed on the blanking belt and the suction cup is released, so that the blanking can be smoothly carried out.
