[0002] With the rapid development of the smartphone industry and the intensification of market competition, higher requirements have been placed on the precision, automation and assembly speed of mobile phone manufacturing processes. Traditional mobile phone side key assembly mostly relies on manual operation, which is not only inefficient, but also frequently causes assembly quality problems due to manual errors, seriously affecting product quality.

The first driving motor 72 controls and drives the first sliding member 73 to slide along the first slide rail 71 along the X-axis to realize the precise horizontal transfer of the middle frame 11. The first lifting electric cylinder fixed on the first sliding member 73 can be extended and retracted in the vertical direction, thereby driving the first vacuum adsorption member 74 to be lifted and lowered, and the middle frame 11 can be grabbed or placed at different heights to ensure the automation level and overall flexibility of the automatic feeding mechanism 3 and the automatic discharging mechanism 4. The vacuum adsorption member in this embodiment is composed of a fixed plate fixedly connected to the lifting rod at the bottom of the lifting cylinder, four vacuum suction heads 103 installed on the fixed plate for adsorbing the middle frame 11, and a vacuum generator or vacuum pump system capable of controlling the suction force of the vacuum suction head 103. By changing the vacuum degree of the vacuum suction head 103, the picking and placing during the handling and migration process are realized, and automation and mechanization are realized, thereby improving the working efficiency of the system. In addition, four long holes are arranged on the fixed plate.

The middle frame 11 to be assembled can be placed on the flip platform 8, and the middle frame 11 can be accurately flipped to the side where the side keys need to be assembled through a pre-programmed mechanical control system. The storage mechanism 9 is a vibrating material tray and is closely adjacent to the flip platform 8 and the mechanical assembly mechanism 10, located on the side of the flip platform 8. The tray can store a large number of side keys, and through the automatic discharging mechanism, ensure that the side keys are supplied to the mechanical assembly mechanism 10 in an orderly and efficient manner according to the production rhythm. And the side keys automatically sent out by the vibrating material tray in the storage mechanism 9 are sucked, and the side keys are accurately assembled to the preset side positions of the middle frame 11 through precise control, effectively improving the speed and accuracy of assembly.

[0043] like Figure 5 As shown, the mechanical assembly mechanism 10 of this embodiment includes a fixed platform 101 fixed on the control platform 1, a mechanical arm 102 for assembling side keys installed on the fixed platform 101, and a vacuum suction head 103 for sucking side keys arranged under the mechanical arm 102.

The end of the mechanical arm 102 is equipped with a vacuum suction head 103 dedicated to sucking side keys. The suction head generates negative pressure through the vacuum generator, which can firmly absorb the side keys to be assembled in the storage mechanism 9. When the mechanical arm 102 moves to the preset assembly position of the middle frame 11, the vacuum suction head 103 accurately places the sucked side keys on the specified position of the middle frame 11 and then presses and installs them, thereby realizing the automatic assembly of the side keys and the middle frame 11.

[0044] like Figure 4As shown, the automatic transport mechanism 6 of this embodiment includes a gantry 61 fixedly mounted between the outlet of the conveyor belt 2 and the automatic positioning assembly 5, a second slide rail 62 is transversely arranged on the top of the gantry 61 near the side of the automatic positioning assembly 5, a second slide member 63 that can slide along the X-axis of the second slide rail 62 is slidably arranged on the second slide rail 62, and a second drive motor 64 is fixedly arranged for driving the second slide member 63 to slide, and an adsorption and taking assembly 65 for sucking and placing the middle frame 11 on the conveyor belt 2 on the flip platform 8 and an adsorption and returning assembly 66 for putting the assembled middle frame 11 back to the conveyor belt 2 are installed on the second slide member 63. The adsorption and taking assembly 65 and the adsorption and returning assembly 66 are fixedly mounted between the outlet of the conveyor belt 2 and the automatic positioning assembly 5 through the gantry 61, and the gantry 61 plays a supporting and guiding role. A second slide rail 62 extending transversely is arranged on the side of the top of the gantry 61 near the automatic positioning assembly 5, and the slide rail is arranged along the X-axis direction. A second sliding member 63 is mounted on the second slide rail 62 and can slide freely along the slide rail. The sliding movement of the second sliding member 63 is controlled and driven by a second driving motor 64 fixed on the gantry 61 .

[0045] like Figure 4As shown, the adsorption and picking assembly 65 of this embodiment mainly includes a second lifting cylinder 651 fixedly mounted on the second sliding member 63, and a vacuum suction cup 652 directly fixed to the lifting rod at the bottom of the second lifting cylinder 651. By precisely controlling the telescopic action of the lifting rod inside the second lifting cylinder 651, the lifting and lowering movement of the vacuum suction cup 652 along the Z-axis direction can be achieved. In actual operation, when it is necessary to grasp and carry the positioned middle frame 11, the vacuum suction cup 652 is first driven downward by the lifting cylinder until it contacts and fits the surface of the middle frame 11, and the vacuum suction cup 652 is started to generate negative pressure to firmly adsorb the middle frame 11.

The third lifting cylinder 661 is mainly responsible for the lifting and lowering movements in the vertical direction (Z axis), ensuring that the adsorption component can accurately lift the middle frame 11 that has completed the side key assembly. The Y-axis electric cylinder 662 assumes the translation function in the horizontal direction (Y axis), which can drive the second vacuum adsorption component 663 to move along the Y-axis direction, accurately placing the assembled middle frame 11 from the flip platform 8 to the position close to the exit of the conveyor belt 2, and then being transported to the next production process by the automatic discharge mechanism 4, ensuring the continuity and high-precision automatic operation of the entire production process, and effectively improving the efficiency and accuracy of the side key assembly of the mobile phone.

[0046] The working process of the automatic assembly machine of this embodiment is to use the automatic feeding mechanism 3 installed at the entrance of the conveyor belt 2, and use the first vacuum adsorption member 74 under the coordinated action of the first sliding member 73 and the first driving motor 72 to accurately grab and place the mobile phone middle frame 11 of the upstream process on the conveyor belt 2 in the X-axis and the plane vertical direction according to the preset trajectory, and ensure that the middle frame 11 is accurately positioned through the adjustable automatic positioning component 5. The positioning component is composed of two parallel limit rods 51 and the expansion part 53 and the stop block 54 therebetween, which can adapt to the middle frame 11 of different widths, and adjust the spacing of the limit rods 51 through the adjustment block 55 and the adjustment rod 56 for precise positioning. After positioning, the automatic transport mechanism 6 controls the adsorption and picking component 65 through the second sliding member 63 and the second driving motor 64 on the gantry 61 to suck the middle frame 11 from the conveyor belt 2 and transport it to the flip platform 8. On the flipping platform 8, the middle frame 11 is precisely flipped to a position suitable for assembling the side keys. At the same time, the automatic assembly device supplies the side keys in order through the material storage mechanism 9 (vibrating material tray), and the mechanical arm 102 and the vacuum suction head 103 of the mechanical assembly mechanism 10 suck the side keys, and the side keys are precisely pressed and assembled to the preset position of the middle frame 11 through precise control. The assembled middle frame 11 is put back to the conveyor belt 2 by the adsorption and return component 66 of the automatic handling mechanism 6. When the assembled mobile phone middle frame 11 reaches the exit of the conveyor belt 2, the automatic unloading mechanism 4 grabs the assembled middle frame 11 from the conveyor belt 2 and transports it to the next process.

[0047] To sum up, the beneficial effects of this embodiment are as follows: this embodiment greatly reduces manual participation and reduces errors caused by manual operation by integrating functional modules such as automatic feeding, positioning, handling, flipping assembly and unloading, and effectively improves the automation and high precision of mobile phone side key assembly.
