[0002] The mobile phone mid-plate is a bracket used to install electrical components inside the mobile phone and to divide the internal space of the mobile phone. During the production of the mobile phone mid-plate, laser engraving equipment is used to laser engrave one side of the mid-plate and then transport it to the next station for processing. Currently, after laser engraving the mid-plate of a mobile phone, the existing conveying equipment uses a robotic arm to drive the grippers to clamp and flip the mid-plate. However, during the clamping and flipping process, if the gripping force of the grippers is too large, it is easy to crush the laser engraved area of ​​the mid-plate.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-12 The present invention provides a technical solution: an automated laser engraving flipping and conveying device for a mobile phone midplate, comprising a fixed frame 1, an arc-shaped cover 2 fixed between the inner walls of the two sides of the fixed frame 1, one side of the arc-shaped cover 2 being open near the bottom, a transmission device being provided on one side of the fixed frame 1, a roller 17 being rotatably arranged between the inner walls of the two sides of the fixed frame 1 inside the arc-shaped cover 2, a plurality of rectangular grooves 24 being equidistantly opened on the outer surface of the roller 17, a slanted guide opening 25 being opened on the inner wall of one side of the plurality of rectangular grooves 24 near the top edge, a suction device being provided inside the plurality of rectangular grooves 24, and an adjustment component being provided inside the roller 17; A laser engraving machine 3 is installed on the other side of the arc-shaped cover 2. One side of the laser engraving machine 3 extends into the interior of the arc-shaped cover 2. A first side frame 4 is fixed between the inner walls of the two sides of the fixing frame 1 near the bottom of the arc-shaped cover 2. A second side frame 5 is installed on one side of the arc-shaped cover 2 at the middle of the opening. Both ends of the second side frame 5 are fixed to the inner edge of the arc-shaped cover 2. Conveyor belts 6 are installed inside both the first side frame 4 and the second side frame 5. The top of the conveyor belt 6 inside the first side frame 4 is located below the bottom of the arc-shaped cover 2. Multiple guide plates 22 are fixed between the tops of the second side frame 5 near one edge. A rotating shaft 33 is rotatably installed between the inner walls of the two sides of the multiple guide plates 22 near one edge. A paddle plate 23 is fixed to the outer surface of the multiple rotating shafts 33. An elastic lifting plate 35 is fixed to one end of the multiple paddle plates 23. One end of the multiple elastic lifting plates 35 extends into the interior of the inclined guide port 25. An annular sleeve 44 is fixed to one side of the multiple guide plates 22. One end of the multiple rotating shafts 33 extends into the inner side of the annular sleeve 44. A worm spring 20 is fixed to the inner wall of the multiple annular sleeves 44. One end of the multiple worm springs 20 is fixed to the outer surface of the rotating shaft 33.

[0019] The effect achieved is that the transmission device drives the roller 17 to rotate intermittently, thereby adsorbing and conveying the middle plate frame 34 conveyed by the conveyor belt 6 on the first side frame 4. During the conveying process, the middle plate frame 34 is laser-engraved and flipped. When the roller 17 rotates, it triggers the adjustment component to control the adsorption device to adsorb and fix the middle plate frame 34, preventing the middle plate frame 34 from falling off during the conveying and transfer process. When the rectangular groove 24 rotates to the opening of the arc-shaped cover 2, one end of the guide plate 39 will slide out from one side of the arc-shaped strip 15 to the bottom surface of the annular opening 21, connecting the bending hole 43 and the bending flow channel 41, relieving the negative pressure state inside the rectangular groove 24. Under the elastic force of the return spring 29, the sliding plate 27 can be driven to slide upward. At the same time, with the rotation of the roller 17, one end of the elastic lifting plate 35 is inserted into the bottom of one side of the elastic rubber frame 31 and is located at the bottom of the middle plate frame 34. At this time, the middle plate frame 34 can be lifted up and enter the guide plate 22 along the push plate 23 to complete the unloading. The push plate 23 is connected to the worm spring 20 through the rotating shaft 33. The rotation torque can be increased by the worm spring 20. When the elastic lifting plate 35 contacts the inclined guide port 25, the elastic lifting plate 35 is lifted up with the rotation of the roller 17 to complete the lifting work and avoid mechanical interference with the roller 17.

[0020] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 and Figure 12 As shown, the transmission device includes a spacer disc 8. An air chamber 16 is formed in the middle of the interior of the roller 17. A pipe fitting 7, communicating with the air chamber 16, is fixed to one end of the roller 17. One end of the pipe fitting 7 slides through to the outside of the fixed frame 1. A motor 19 is embedded inside one side of the fixed frame 1. The spacer disc 8 is fixed to the outer surface of the pipe fitting 7. A transmission disc 11 is rotatably engaged on one side of the outer surface of the fixed frame 1, and one side of the transmission disc 11 is fixed to the output end of the motor 19. A disc 12 is fixed to one side of the transmission disc 11, and a notch 14 is formed on one side of the disc 12. The transmission disc 11 is positioned against... A lever 13 is fixed near the edge of the outer surface. The lever 13 is located on one side of the notch 14. Multiple arc-shaped openings 9 are equidistantly opened on the outer surface of the spacer 8. The arc surface of one side of the disc 12 slides and slides against the inner wall of the arc-shaped opening 9. A lever opening 10 is opened between two adjacent arc-shaped openings 9 on the outer surface of the spacer 8. An arc-shaped strip 15 is fixed on the inner wall of one side of the fixing frame 2. An annular opening 21 is opened on the outer surface of one side of the roller 17. One side of the arc-shaped strip 15 extends into the interior of the annular opening 21 and slides against the bottom surface inside the annular opening 21. The arc-shaped opening of the arc-shaped strip 15 is opposite to the opening of the arc-shaped cover 2.

[0021] The effect achieved is as follows: the starting motor 19 drives the transmission disk 11 to rotate. When the transmission disk 11 rotates, it drives the disc 12 and the lever 13 to rotate. When the disc 12 rotates, its arc surface on one side fits against the inner wall of the arc-shaped opening 9 on the spacer disc 8, thereby limiting the spacer disc 8 and preventing the roller 17 from rotating. During the rotation of the disc 12, when the notch 14 is opposite to the arc-shaped opening 9, the lever 13 is inserted into the dial 10 to divide the spacer disc 8, causing it to drive the roller 17 to rotate intermittently. During the pause between the intermittent rotations of the roller 17, the laser engraving machine 3 laser engraves the bottom of the middle plate frame 34, and simultaneously performs material suction and discharge. The middle plate frame 34 can be flipped during the rotation of the roller 17.

[0022] like Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 11 As shown, the suction device includes a sliding plate 27, which is disposed inside a rectangular groove 24. A limit frame 26 is fixed between the inner walls of the rectangular groove 24 near the bottom. A limit strip 45 is fixed above the limit frame 26 on one side of the inner wall of the rectangular groove 24. A movable frame 28 is fixed near the bottom on the outer surface of the sliding plate 27. The movable frame 28 slides against the inner walls of the rectangular groove 24. One side of the limit strip 45 slides against the outer surface of the sliding plate 27. A through hole 30 extending to the bottom is opened at the top of the sliding plate 27. A return spring 29 is fixed between the bottom of the sliding plate 27 and the inner bottom surface of the rectangular groove 24. A pad frame 32 is fixed at the top of the sliding plate 27. An elastic rubber frame 31 is provided on the outer surface of the pad frame 32. A middle plate frame 34 is provided between the tops of the elastic rubber frames 31.

[0023] The effect achieved is that, during the intermittent rotation of the roller 17, when the rectangular groove 24 on the outer surface of the roller 17 rotates to directly below and above the top of the conveyor belt 6 on the first side frame 4, it will be sealed by the elastic rubber frame 31 pressing against the top edge of the middle plate frame 34, thus sealing the top of the middle plate frame 34 and the opening of the rectangular groove 24. At this time, one side of the arc strip 15 pushes one end of the guide plate 39 into the inward slide rail 36, causing the rectangular groove 24 to be sucked downward by the negative pressure inside, along with the sliding plate 27 and the middle plate frame 34, until the bottom of the movable frame 28 contacts the top of the limiting frame 26. When the groove 24 rotates to the opening of the arc-shaped cover 2, one end of the guide plate 39 will slide out from one side of the arc-shaped strip 15 to the bottom surface inside the annular opening 21, connecting the bending hole 43 and the bending flow channel 41, thus relieving the negative pressure inside the rectangular groove 24. At this time, under the elastic force of the return spring 29, the sliding plate 27 can be driven to slide upward. At the same time, in conjunction with the rotation of the roller 17, one end of the elastic lifting plate 35 is inserted into the bottom side of the elastic rubber frame 31 and located at the bottom of the middle plate frame 34. At this time, the middle plate frame 34 can be lifted up, allowing the middle plate frame 34 to enter the guide plate 22 along the push plate 23, completing the unloading.

[0024] like Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 10 and Figure 11 As shown, the adjustment assembly includes multiple guide plates 39. Multiple inner slides 36, extending through one end of the roller 17, are equidistantly provided on the inner bottom surface of the annular opening 21. The guide plates 39 slide within the inner slides 36. Multiple rectangular grooves 24 have air passages 18 extending through the air chamber 16 on their inner bottom surfaces. These air passages 18 intersect with the inner slides 36. Multiple through holes 42 are equidistantly provided on the top of each guide plate 39. Bent flow channels 4 are formed between the air passages 18 located directly above the guide plates 39. 1. One end of the bent flow channel 41 extends to the top surface of the inner slide 36. One end of the guide plate 39 is provided with a bending hole 43. One end of the bending hole 43 extends to the top of the guide plate 39 and is located outside one end of the bent flow channel 41. The top and bottom surfaces of the inner slide 36 are provided with side openings 37 near one edge. The top and bottom of the guide plate 39 are provided with constraint openings 40. One side inner wall of each of the side openings 37 is fixed with an arc-shaped spring piece 38. One end of each of the arc-shaped spring pieces 38 is correspondingly engaged inside the constraint opening 40.

[0025] The effect achieved is that the pipe fitting 7 is rotatably connected to the end of the externally supplied negative pressure pipe. During the intermittent rotation of the roller 17, when the rectangular groove 24 on the roller 17 is inside the arc-shaped cover 2, one end of the guide plate 39 is pushed into the inward slide rail 36 by one side of the arc-shaped strip 15. At this time, the through hole 42 and the air passage 18 are interconnected, and the negative pressure adsorption force inside the air chamber 16 can be transmitted to the rectangular groove 24 through the air passage 18. When the rectangular groove 24 rotates to the open part of the arc-shaped cover 2, the guide plate... One end of guide plate 39 will slide out from one side of the arc-shaped strip 15 to the bottom surface of the annular opening 21. At this time, because guide plate 39 slides to one side, through hole 42 will slide to the position opposite to air passage 18, cutting off air passage 18. At the same time, bending hole 43 at one end of guide plate 39 will slide to the position where bending flow channel 41 connects with inner slide channel 36, so that bending hole 43 and bending flow channel 41 are interconnected. After external air is injected into air passage 18 through bending flow channel 41, it enters the interior of rectangular groove 24, releasing the negative pressure adsorption inside rectangular groove 24.

[0026] Working principle: The middle plate frame 34 is placed on the first side frame 4 and conveyed to the bottom of the arc-shaped cover 2 by the conveyor belt 6. The starting motor 19 drives the transmission disc 11 to rotate. When the transmission disc 11 rotates, it drives the disc 12 and the lever 13 to rotate. When the disc 12 rotates, one side of its arc surface fits against the inner wall of the arc-shaped opening 9 on the spacer disc 8, thus limiting the spacer disc 8 and preventing the roller 17 from rotating. During the rotation of the disc 12, when the notch 14 is aligned with the arc-shaped opening 9, the lever 13 is inserted into the dial 10 to divide the spacer disc 8, causing it to drive the roller 17 to rotate intermittently. During the pause between the intermittent rotations of the roller 17, the bottom of the middle plate frame 34 is laser-engraved by the laser engraving machine 3 to engrave the tube. The sleeve 7 is rotatably connected to the end of the external negative pressure supply pipe. During the intermittent rotation of the roller 17, when the rectangular groove 24 on the roller 17 is inside the arc-shaped cover 2, one end of the guide plate 39 is pushed into the inner slide rail 36 by one side of the arc-shaped strip 15. At this time, the through hole 42 and the air passage 18 are interconnected, and the negative pressure adsorption force inside the air chamber 16 can be transmitted to the rectangular groove 24 through the air passage 18. When the rectangular groove 24 rotates to the opening of the arc-shaped cover 2, one end of the guide plate 39 will slide out from one side of the arc-shaped strip 15 to the bottom surface inside the annular opening 21. At this time, because the guide plate 39 slides to one side, the through hole 42 will slide to the position opposite to the air passage 18, cutting off the air passage 18. At the same time, the guide plate 39 will slide to the position opposite to the misalignment of the through hole 42. The bending hole 43 at one end of the 9 will slide to the point where the bending flow channel 41 connects with the inner slide 36, so that the bending hole 43 and the bending flow channel 41 are interconnected. After the external air is injected into the air passage 18 through the bending flow channel 41, it enters the interior of the rectangular groove 24, releasing the negative pressure adsorption inside the rectangular groove 24. During the intermittent rotation of the roller 17, when the rectangular groove 24 on the outer surface of the roller 17 rotates to the point directly below and above the top of the conveyor belt 6 on the first side frame 4, it will be sealed by the elastic rubber frame 31 pressing against the top edge of the middle plate frame 34, thus sealing the top of the middle plate frame 34 and the opening of the rectangular groove 24. At this time, one side of the arc strip 15 pushes one end of the guide plate 39 into the interior of the inner slide 36, so that the interior of the rectangular groove 24 is filled with negative pressure. The sliding plate 27, together with the middle plate frame 34, is drawn downwards until the bottom of the movable frame 28 contacts the top of the limiting frame 26. When the rectangular groove 24 rotates to the opening of the arc-shaped cover 2, one end of the guide plate 39 will slide out from one side of the arc-shaped strip 15 to the bottom surface inside the annular opening 21, connecting the bending hole 43 and the bending flow channel 41, thus relieving the negative pressure inside the rectangular groove 24. At this time, the sliding plate 27 can be driven to slide upwards under the elastic force of the return spring 29. At the same time, with the rotation of the roller 17, one end of the elastic lifting plate 35 is inserted into the bottom side of the elastic rubber frame 31 and located at the bottom of the middle plate frame 34. At this time, the middle plate frame 34 can be lifted up, allowing the middle plate frame 34 to enter the guide plate 22 along the push plate 23, completing the unloading.
