[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0022] Example:

[0023] refer to Figures 1-7 The device shown is an automatic screw-locking device for flipping and rotating the back panel of a mobile phone. It includes a base with a first streamline 1 and a second streamline 2. A screw feeding and detection mechanism 3 is arranged beside the first streamline 1 and the second streamline 2. A carrier flipping mechanism 4, a first conveyor screw-locking mechanism 5 and a second conveyor screw-locking mechanism 6 are fixedly connected to the base beside the first streamline 1 and the second streamline 2. The carrier flipping mechanism 4 includes a flipping linear module 401, a flipping motor 402, a flipping carrier plate 403, a vacuum nozzle 404, a pressing cylinder 405, a pressure plate 406, a clamping cylinder 407 and a clamping plate 408. The first conveyor screw-locking mechanism 5 includes a carrier transfer robot 501, an XYZ moving module 502, a guide camera 503, an automatic screw-locking mechanism 504 and a gantry frame 505. The second conveyor screw-locking mechanism 6 has the same structure as the first conveyor screw-locking mechanism 5.

[0024] The screw feeding and inspection mechanism 3 includes a first screw feeder 301, a second screw feeder 302, a lower CCD camera 303, and a side CCD camera 304. The lower CCD camera and the side CCD camera 304 can detect whether the screws have defects. (When the automatic screw locking mechanism 504 picks up the screw at the first screw feeder 301 or the second screw feeder 302, the screw is in a vertical position with the larger end facing up. The bit of the automatic screw locking mechanism 504 rotates and presses down vertically until it is locked into the hole on the screw to complete the alignment. Then, the screw is transferred by the magnetic attraction of the bit.) The first screw feeder 301 and the second screw feeder 302 are used to feed the screws. An NG (not good) material box is set on the machine base next to the first screw feeder 301 and the second screw feeder 302 to collect NG screws.

[0025] The flipping linear module 401 is used to drive the flipping motor 402 to translate, so that the flipping carrier plate 403 can switch between the first carrier screw-locking mechanism 5 and the second carrier screw-locking mechanism 6. The flipping carrier plate 403 is fixedly connected to the rotating shaft of the flipping motor 402. The flipping motor 402 can drive the flipping carrier plate 403 to flip and adjust its angle. The extension and retraction of the piston rod of the clamping cylinder 405 can drive the pressure plate 406 to lift and lower to realize the vertical clamping action on the mobile phone back panel. The extension and retraction of the piston rod of the clamping cylinder 407 can drive the clamping plate 408 to clamp the carrier of the mobile phone back panel in the horizontal direction.

[0026] A positioning rod is fixedly connected to the flip carrier plate 403. The positioning rod is used to position and place the carrier that loads the mobile phone back panel. The vacuum nozzle 404 is located in the clearance hole. Some of the vacuum nozzles 404 are used to adsorb and fix the carrier that loads the mobile phone back panel. When the carrier is positioned, some of the vacuum nozzles 404 will be inserted into the hole groove on the carrier to adsorb the mobile phone back panel. The clamping plate 408 is located in the clearance groove. The clamping plate 408 is L-shaped in general.

[0027] The carrier transfer robot 501 is used to transfer the carrier that loads the mobile phone back panel. The XYZ mobile module 502 is used to drive the guide camera 503 and the screw automatic fastening mechanism 504 to move and realize visual guidance and screw automatic fastening.

[0028] An elastic slide block is slidably connected to the moving platform of the XYZ mobile module 502. A spring and a pressure sensor are provided between the elastic slide block and the moving platform of the XYZ mobile module 502. The elastic structure is set to avoid damage to the back panel of the mobile phone when tightening the screw. The pressure sensor is used to detect whether the screw is tightened in place when it is pressed down.

[0029] The working principle of this utility model is as follows: When in use, the carrier transfer manipulator 501 of the first carrier screw-locking mechanism 5 grabs the carrier carrying the mobile phone back panel and moves it onto the flipping carrier plate 403. After the carrier is placed along the positioning rod, the carrier transfer manipulator 501 releases its grip and resets. Then, the piston rod of the clamping cylinder 407 extends, and the bent section of the clamping plate 408 clamps the carrier laterally. Subsequently, the piston rod of the pressing cylinder 405 retracts, and the pressure plate 406 descends vertically to press the carrier vertically, thus completing the carrier transfer. After fixing, the flip motor 402 drives the flip carrier plate 403 to flip and adjust the angle. Then, the flip linear module 401 drives the flip carrier plate to the screw fastening station. The first screw feeder 301 feeds the screw automatic fastening mechanism 504. The XYZ moving module 502 drives the screw automatic fastening mechanism 504 to move to the screw fastening station. The screw is automatically fastened to the back of the mobile phone by the screw automatic fastening mechanism 504. The feeding and fastening action at the second conveyor screw fastening mechanism 6 is the same as above.

[0030] After the locking is completed, the flipping carrier plate 403 is reset, the clamping cylinder 405 and clamping cylinder 407 at the carrier are released, and the carrier is transferred to the first flow line 1 or the second flow line 2 for unloading by the carrier transfer robot 501.
