[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Embodiment:

[0023] Refer to Figures 1 - 7 Shown is an automatic flipping and screw-locking device for a mobile phone backplane, including a machine base. A first streamline 1 and a second streamline 2 are arranged on the machine base. A screw feeding and detecting mechanism 3 is arranged beside the first streamline 1 and the second streamline 2. A carrier flipping mechanism 4, a first carrier screw-locking mechanism 5 and a second carrier screw-locking mechanism 6 are fixedly connected beside the first streamline 1 and the second streamline 2 on the machine base. The carrier flipping mechanism 4 includes a flipping linear module 401, a flipping motor 402, a flipping carrier plate 403, a vacuum suction nozzle 404, a pressing cylinder 405, a pressing plate 406, a clamping cylinder 407 and a clamping plate 408. The first carrier screw-locking mechanism 5 includes a carrier transfer manipulator 501, an XYZ moving module 502, a guiding camera 503, an automatic screw-locking mechanism 504 and a gantry 505. The second carrier screw-locking mechanism 6 has the same structure as the first carrier screw-locking mechanism 5.

[0024] The screw feeding and detecting 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 there are defects in the screws (when the screw automatic locking mechanism 504 picks up screws at the first screw feeder 301 or the second screw feeder 302, the screws are in a vertical state with the large head facing up. After the bit of the screw automatic locking mechanism 504 rotates vertically and presses down until it snaps into the hole groove on the screw to complete alignment, the screw is transported by magnetic adsorption of the bit). The first screw feeder 301 and the second screw feeder 302 are used for feeding screws. An NG bin is arranged on the machine base beside the first screw feeder 301 and the second screw feeder 302 to collect defective 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 carrying and screwing mechanism 5 and the second carrying and screwing 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 telescopic movement of the piston rod of the pressing cylinder 405 can drive the pressing plate 406 to lift and lower to achieve the pressing action in the vertical direction on the loaded mobile phone backplane. The telescopic movement of the piston rod of the clamping cylinder 407 can drive the clamping plate 408 to clamp the carrier of the loaded mobile phone backplane in the horizontal direction.

[0026] A positioning rod is fixedly connected to the flipping carrier plate 403. The positioning rod is used to position and place the carrier of the loaded mobile phone backplane. The vacuum suction nozzles 404 are located in the relief holes. Some of the vacuum suction nozzles 404 are used to adsorb and fix the carrier of the loaded mobile phone backplane. Some of the vacuum suction nozzles 404 will insert into the hole grooves on the carrier to adsorb the mobile phone backplane when the carrier is positioned and placed. The clamping plate 408 is located in the relief groove, and the clamping plate 408 is integrally L-shaped.

[0027] The carrier transfer manipulator 501 is used to transfer the carrier of the loaded mobile phone backplane. The XYZ moving module 502 is used to drive the guiding camera 503 and the screw automatic locking mechanism 504 to move to achieve visual guidance and automatic screw locking processing.

[0028] An elastic sliding seat is slidably connected to the moving platform of the XYZ moving module 502. A spring and a pressure sensor are arranged between the elastic sliding seat and the moving platform of the XYZ moving module 502. The elastic structure is set to avoid damaging the mobile phone backplane when locking the screw. The pressure sensor is used to detect whether the screw is locked in place when pressing down and locking the screw.

[0029] The working principle of the present invention is as follows: When the present invention is in use, the carrier transfer manipulator 501 of the first carrier screw locking mechanism 5 grabs the carrier loaded with the mobile phone backplane and moves it to the turnover plate 403. After the carrier is placed along the positioning rod, the carrier transfer manipulator 501 releases the clamp and resets. Then, the piston rod of the clamping cylinder 407 extends, and the bent section of the clamping plate 408 will clamp the carrier horizontally. Subsequently, the piston rod of the pressing cylinder 405 retracts, and the pressing plate 406 descends vertically to press the carrier vertically. After the fixation of the carrier is completed, the turnover motor 402 drives the turnover plate 403 to turn and adjust the angle. Then, the turnover linear module 401 drives the turnover plate to the screw locking station. The first screw feeder 301 supplies materials to the screw automatic locking mechanism 504. The XYZ moving module 502 drives the screw automatic locking mechanism 504 to move to the screw locking station, and the screw automatic locking mechanism 504 automatically locks the screws on the mobile phone backplane. The feeding and locking actions at the second carrier screw locking mechanism 6 are the same as above;

[0030] After the locking is completed, the turnover plate 403 resets, the pressing cylinder 405 and the clamping cylinder 407 at the carrier release the clamp, and the carrier is transferred to the first streamline 1 or the second streamline 2 for unloading by the carrier transfer manipulator 501.

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components.
