DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The high-efficiency and high-precision automated assembly machine comprises a mounting plate 1, a precise positioning mechanism, a conveying mechanism and a rear shell fixing and moving mechanism. The precise positioning mechanism comprises a pressure sensor 2, which is fixedly mounted inside the mounting plate 1. A slide groove 3 is provided inside the mounting plate 1. A setting groove 4 is provided inside the mounting plate 1. A first electric slide rail 5 is installed inside the mounting plate 1. A first slider 6 is provided inside the first electric slide rail 5. A first electric push rod 7 is fixedly mounted on one side of the first slider 6. A card plate 8 is fixedly connected to one end of the first electric push rod 7. The slide groove 3 is connected to the setting groove 4. The first slider 6 is slidably connected to the first electric slide rail 5, and the first electric slide rail 5 is electrically connected to the pressure sensor 2. When the mobile phone is transported through the conveying mechanism and the slide groove 3, the mobile phone enters the setting groove 4, and then the position of the card plate 8 can be adjusted by the setting of the first electric slide rail 5 and the first electric push rod 7 to clamp and move the mobile phone, so that the mobile phone can contact the pressure sensor 2. When contacting the pressure sensor 2, the first electric slide rail 5 will stop, thereby accurately positioning the position of the mobile phone, so that the assembly accuracy can be higher when assembling the back shell.

[0020] In one aspect of the present embodiment, when a mobile phone that needs to be assembled with a mobile phone back shell needs to be assembled, the mobile phone needs to be placed on the conveyor belt 11 first, and then the motor 9 is started to drive the transmission shaft 10 to rotate. When the transmission shaft 10 rotates, the conveyor belt 11 and the stabilizing shaft 12 can be driven to rotate. The stabilizing shaft 12 can ensure that the conveyor belt 11 rotates stably for conveying. When the conveyor belt 11 rotates for conveying, the mobile phone on the conveyor belt 11 can be conveyed, and the mobile phone is conveyed out from the other end of the conveyor belt 11, so that the mobile phone can fall onto the slide 3 for subsequent assembly processes.

[0021] In one aspect of the present embodiment, the mobile phone back shells that need to be assembled are placed in batches in the placement rack 22. When the mobile phone back shells need to be taken out and assembled, the second electric slide rail 13 and the third electric slide rail 16 are electrically connected to the pressure sensor 2, and the second electric slide rail 13 and the third electric slide rail 16 are controlled by PLC, so that the second electric slide rail 13 and the third electric slide rail 16 have a specific motion trajectory. The second electric slide rail 13 is started to drive the second slider 14 to move, thereby adjusting the position of the gantry 15. The third electric slide rail 16 is started to drive the third slider 17 to move, so that the third slider 17 drives the suction cup 21 to move left and right through the connecting plate 18, the second electric push rod 19 and the vacuum pump 20. The cooperation of the second electric push rod 19 and the vacuum pump 20 can make the suction cup 21 absorb and move the mobile phone back shell from the placement rack 22, and then move the mobile phone back shell to the upper side of the mobile phone, and the second electric push rod 19 drives the collection back shell to move downward to press the corresponding buckling point, so that it is completely buckled and assembled.

[0022] In one aspect of this embodiment, the assembly machine is supported by the base 24 contacting the ground. When the height of the assembly machine needs to be adjusted, the third electric push rod 23 can be activated to extend and retract, thereby directly adjusting the height of the assembly machine so that the assembly machine can operate at a suitable height.

[0023] The working principle of the utility model: when the efficient and accurate automatic assembly machine is in use, the mobile phone needs to be placed on the conveyor belt 11 first, and then the motor 9 is started to drive the transmission shaft 10 to rotate. When the transmission shaft 10 rotates, the conveyor belt 11 and the stabilizing shaft 12 can be driven to rotate. The stabilizing shaft 12 can ensure the stable rotation and conveying of the conveyor belt 11. When the conveyor belt 11 rotates and conveys, the mobile phone on the conveyor belt 11 can be conveyed, and the mobile phone is conveyed out from the other end of the conveyor belt 11 so that the mobile phone can fall onto the slide 3, and then the mobile phone will slide into the setting groove 4 through the slide 3. After that, the position of the card plate 8 can be adjusted by setting the first electric slide rail 5 and the first electric push rod 7 to clamp and move the mobile phone, so that the mobile phone can contact the pressure sensor 2. When contacting the pressure sensor 2, the first The electric slide rail 5 will stop, thereby accurately positioning the position of the mobile phone. When the mobile phone contacts the pressure sensor 2, the second electric slide rail 13 drives the second slider 14 to move, thereby adjusting the position of the gantry 15. The third electric slide rail 16 drives the third slider 17 to move, so that the third slider 17 drives the suction cup 21 to move left and right through the connecting plate 18, the second electric push rod 19 and the vacuum pump 20. The cooperation of the second electric push rod 19 and the vacuum pump 20 can make the suction cup 21 suck the back shell of the mobile phone out of the placement rack 22 and move it, and then move the back shell of the mobile phone to the upper side of the mobile phone, and drive the collection back shell to move down through the second electric push rod 19 to press the corresponding buckling point, so that it is completely buckled and assembled. All electrical equipment in this solution is powered by PLC.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
