Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of folding screen mobile phone flip plate correction, and particularly relates to an automatic leveling device for a folding mobile phone rotating shaft. BACKGROUND

[0002] The folding screen mobile phone requires a flexible screen with high flexibility, and the mobile phone hardware such as a mobile phone substrate, a mobile phone back cover and a PCBA board needs to be separated into two parts through a hinge system. The rotating shaft flip plate is one of the most critical parts in the hinge system of the folding screen mobile phone. It is usually a pair of metal plates with a specific profile curve and a groove. Through the relative sliding and engagement of the plates, the mobile phone can be fixed at a specific angle (such as hovering) and provide an opening and closing feeling (damping feeling). It directly determines whether the mobile phone can be smoothly opened and closed and stably hovered.

[0003] The rotating shaft flip plate in the hinge system of the folding screen mobile phone is usually made of metal. During the processing, deformation inevitably occurs. Therefore, subsequent leveling is required to enable the rotating shaft flip plate to be normally connected with the shaft rod of the hinge system and the remaining mobile phone accessories. Since the rotating shaft flip plate is not a whole flat plate, the positions and degrees of deformation are different due to the different thicknesses of the parts. Therefore, different directions and sizes of reset pressure need to be applied to the parts with different degrees and directions of deformation at different positions of the rotating shaft flip plate to complete the leveling.

[0019] The technical solution of the present invention will now be clearly and completely described 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.

[0020] Please refer to Figures 1-11This invention provides a technical solution: an automatic leveling device for a folding mobile phone hinge, used to level uneven areas on the hinge flip plate workpiece 7. It includes a pressure mechanism 3, with a loading visual inspection mechanism 1 and a unloading visual inspection mechanism 2 installed on both sides of the pressure mechanism 3. A pair of mirror-aligned micro-adjustment leveling components 4 and a pair of overall leveling mechanisms 5 are installed on the pressure mechanism 3. A transfer mechanism 6 is also installed on the pressure mechanism 3. The loading visual inspection mechanism 1 is used to visually inspect and position uneven areas on the hinge flip plate workpiece 7. The unloading visual inspection mechanism 2 is used to visually inspect the hinge flip plate workpiece 7 after it has been leveled by the pair of micro-adjustment leveling components 4 and the pair of overall leveling mechanisms 5. The transfer mechanism 6 is used to transfer the hinge flip plate workpiece 7 from the loading visual inspection mechanism 1 to between the pair of micro-adjustment leveling components 4, and then transfer the hinge flip plate workpiece 7 between the pair of micro-adjustment leveling components 4 to between the pair of overall leveling mechanisms 5. Finally, the hinge flip plate workpiece 7 between the pair of overall leveling mechanisms 5 is transferred to the unloading visual inspection mechanism 2.

[0021] The material loading visual inspection mechanism 1 includes a cabinet 11, in which a linear module 12 and a camera 14 are installed. A material carrier platform 13 is fixedly installed on the slider of the linear module 12, and the camera 14 is located above the material carrier platform 13.

[0022] The material unloading visual inspection mechanism 2 includes a cabinet 21, a linear module 22 and a camera 24 installed inside the cabinet 21, a material carrier 23 fixedly installed on the slider of the linear module 22, and the camera 24 located above the material carrier 23.

[0023] The pressure mechanism 3 includes a frame 31, on which a telescopic cylinder 32 is fixedly mounted. The pressure mechanism 3 also includes two mounting plates 33, which are respectively fixed on the frame 31 and the piston rod end of the telescopic cylinder 32. Two fine adjustment leveling components 4 and two overall leveling mechanisms 5 are respectively fixed on the two mounting plates 33.

[0024] The fine-tuning leveling component 4 includes a base 41 fixed on the mounting plate 33. Side frames 42 are provided on both sides of the base 41. The base 41 and the side frames 42 are connected by a connecting frame 43. Multiple motors 47 are fixedly installed on both side frames 42. A leveling mechanism 48 is fixedly installed on the side of the base 41 away from the mounting plate 33. The leveling mechanism 48 includes a mold base 481 fixed on the base 41. A mold shell 482 is fixedly installed on the mold base 481. Multiple rectangular push blocks 485 are slidably installed longitudinally through the mold shell 482. Rectangular adjusting blocks 484 for adjusting the position and height of each rectangular push block 485 are slidably installed through the mold shell 482. Two pressure blocks 483 are fixedly installed on the mold shell 482 to press down the two rows of rectangular adjusting blocks 484. The pressure blocks 483 and the rectangular adjusting blocks 484 are slidably connected. The fine-tuning leveling component 4 also includes a cover 49 fixed on the mounting plate 33 and covering the multiple motors 47 on one side.

[0025] An internally threaded cylinder 46 is fixedly installed on the side of the rectangular adjusting block 484 away from the rectangular pushing block 485. A round shaft 44 is rotatably mounted through the connecting frame 43. A screw 45 is fixedly installed on the end of the round shaft 44 near the internally threaded cylinder 46. The screw 45 is threadedly connected to the internally threaded cylinder 46. Multiple motors 47 are fixedly installed on the side of the side frame 42 away from the base 41. The output shafts of the multiple motors 47 are used to drive the corresponding round shaft 44 located on the same side to rotate.

[0026] The rectangular adjusting block 484 has a ramp 4841 at one end near the rectangular pushing block 485, a second ramp 4851 adapted to the first ramp 4841 at the bottom end of the rectangular pushing block 485, and a pushing part 4852 at the end of the rectangular pushing block 485 away from the second ramp 4851.

[0027] A positioning rod 486 is fixedly installed inside the mold shell 482. Multiple rectangular push blocks 485 are provided with strip holes 4853. The positioning rod 486 passes through multiple strip holes 4853 and is slidably connected to multiple strip holes 4853.

[0028] Furthermore, multiple motors 47 are connected to the corresponding round shafts 44 via synchronous pulley sets. The motors 47 drive the round shafts 44 to rotate via the synchronous pulley sets. The rotation of the round shafts 44 will pull / push the internal threaded cylinder 46 to move via the motors 47. The internal threaded cylinder 46 will then pull / push the rectangular adjusting block 484 to move. When the upper and lower rectangular push blocks 485 abut against the workpiece 7 on the rotating shaft flip plate, the synchronous movement of the two rectangular adjusting blocks 484 will drive the two rectangular push blocks 485 to move up and down synchronously through the cooperation of the corresponding ramp 1 4841 and ramp 2 4851.

[0029] The overall leveling mechanism 5 includes a second platform 51 fixedly connected to the mounting plate 33. Two rows of positioning blocks 52 are fixedly installed on the side of the second platform 51 away from the mounting plate 33, and a leveling template 53 is fixedly installed between the two rows of positioning blocks 52.

[0030] Furthermore, positioning pins corresponding to the mounting holes on the rotating shaft flip plate workpiece 7 are installed on the leveling template 53 and the pushing part 4852, so as to prevent the rotating shaft flip plate workpiece 7 from shifting during leveling.

[0031] The transfer mechanism 6 includes a linear module 3 61 fixed to the top of the mounting plate 33. The linear module 3 61 is horizontally arranged. A linear module 4 62 is fixedly installed on the slider of the linear module 3 61. Three horizontally arranged and equally spaced crossbars 63 are fixedly installed on the slider of the linear module 4 62. Suction cup 1 64, suction cup 2 65 and suction cup 3 66 are fixedly installed at the bottom of the three crossbars 63 respectively.

[0032] Furthermore, suction cup 1 64 is used to grab the rotating plate workpiece 7 on the loading platform 13 and transfer the rotating plate workpiece 7 to the multiple pushing parts 4852 of the lower overall leveling mechanism 5 in the two micro-adjustment leveling assemblies 4; suction cup 2 65 is used to grab the rotating plate workpiece 7 between the two rotating plate workpieces 7 and transfer the rotating plate workpiece 7 to the lower leveling template 53 in the two overall leveling mechanisms 5; suction cup 3 66 is used to grab the rotating plate workpiece 7 between the two overall leveling mechanisms 5 and transfer the rotating plate workpiece 7 to the loading platform 2 23.

[0033] In this embodiment: When in use, the rotating plate workpiece 7 to be leveled is placed on the loading platform 13, and then the rotating plate workpiece 7 placed on the loading platform 13 is visually inspected by the camera 14, which can detect uneven depressions / protrusions on the rotating plate workpiece 7. Then, the rotating shaft flip plate workpiece 7 on the loading platform 13 is transferred to the two micro-adjustment leveling components 4 by the transfer mechanism 6, and the rotating shaft flip plate workpiece 7 is placed on the top of the multiple push parts 4852 located on the lower micro-adjustment leveling component 4. Then, the upper micro-adjustment leveling component 4 is moved down by the telescopic cylinder 32, so that the upper and lower micro-adjustment leveling components 4 approach each other and clamp the rotating shaft flip plate workpiece 7. Then, based on the detection results of camera 14, the corresponding motor 47 on the overall leveling mechanism 5 is controlled to rotate, so that the two rectangular push blocks 485 located above and below the recessed / protruding position of the rotating shaft flip plate workpiece 7 move up and down synchronously. By pushing the recessed position on the rotating shaft flip plate workpiece 7 upward and pressing the protruding position on the rotating shaft flip plate workpiece 7 downward at the same time by the two rectangular push blocks 485, the leveling operation of the recessed / protruding position on the rotating shaft flip plate workpiece 7 can be completed. Then, the rotating plate workpiece 7, which has been finely adjusted for the concave / protruding positions by the two micro-adjustment leveling components 4, is transferred to the two overall leveling mechanisms 5 by the transfer mechanism 6. The rotating plate workpiece 7 is placed on the leveling template 53 located in the lower overall leveling mechanism 5. Then, the upper overall leveling mechanism 5 is moved down by the telescopic cylinder 32, so that the upper and lower overall leveling mechanisms 5 approach each other and clamp the rotating plate workpiece 7. The rotating plate workpiece 7 is clamped from the top and bottom by the two leveling templates 53. This not only completes the overall leveling of the rotating plate workpiece 7, but also eliminates the stress formed on the part of the rotating plate workpiece 7 after being leveled by the two micro-adjustment leveling components 4. This makes it less likely for the rotating plate workpiece 7 to spring back after being leveled by the two micro-adjustment leveling components 4 and the two overall leveling mechanisms 5. Then, the rotating plate workpiece 7 between the two overall leveling mechanisms 5 is transferred to the loading platform 23 by the transfer mechanism 6. Then, the rotating plate workpiece 7 on the loading platform 23 is moved to the area below the camera 24 by the linear module 22. The camera 24 performs visual inspection on the rotating plate workpiece 7 below. If the rotating plate workpiece 7 is found to be flat, it is qualified. If there are still uneven areas on the rotating plate workpiece 7, it needs to be transferred back to the loading visual inspection mechanism 1 for inspection and leveling again.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
