Description

Technical Field

[0001] This utility model relates to the field of screw-driving device technology, and in particular to an automatic screw-driving device for metal caps and hardware accessories. Background Technology

[0002] In the manufacturing process of hardware components, it is often necessary to fix two hardware components together with screws, such as assembling a sound-producing accessory onto a metal cover. Currently, this is generally done using an automatic screw-driving machine. First, the through-hole of the metal cover is aligned with the threaded hole of the sound-producing accessory. Then, a screw feeding mechanism feeds the screw to the suction nozzle, which delivers the screw to the corresponding position on the metal cover to be screwed in. Finally, an electric screwdriver automatically tightens the screw. However, when the electric screwdriver is used, it generates significant vibration, which can easily cause the metal cover to shift. This can lead to misalignment of the screw with other through-holes when driving subsequent screws. Utility Model Content

[0031] Please check again. Figure 1 The material transfer assembly 30 includes a support frame 31, a transverse block 32, a lifting block 33, and a suction nozzle 34. The support frame 31 is mounted on the machine base 10. The transverse block 32 is slidably mounted on the support frame 31. The lifting block 33 is slidably mounted on the transverse block 32. The suction nozzle 34 is mounted on one end of the lifting block 33 and is used to pick up and place screws. One side of the suction nozzle 34 is connected to a vacuum pump, and the operation of the vacuum pump controls the suction nozzle 34 to pick up or place screws. Optionally, the material transfer assembly 30 also includes a sealing ring (not shown) mounted on the suction nozzle 34. The material transfer assembly 30 also includes a transverse movement force element (not shown) and a lifting power element (not shown). The transverse movement force element is used to drive the transverse block 32 to move, and the lifting power element is used to drive the lifting block 33 to slide.

[0032] In one embodiment, the material transfer assembly 30 further includes a support 35, one end of which is mounted on one end of the lifting block 33, and the suction nozzle 34 is mounted on the end of the support 35 away from the lifting block 33. The material transfer assembly 30 also includes a support block 36, a guide post 37, and a protrusion 38. The support block 36 is mounted on one side of the transverse block 32, the guide post 37 is mounted on the support block 36, and the protrusion 38 is mounted on one end of the lifting block 33, the protrusion 38 abutting against one end of the guide post 37; when the suction nozzle 34 draws material, the protrusion 38 abuts against one end of the guide post 37 to limit the position of the suction nozzle 34. Optionally, the guide post 37 is a threaded post, threadedly connected to the support block 36, to adjust the position of the guide post 37.

[0033] like Figure 1As shown, the screw-driving assembly 40 includes a slider 41, an electric screwdriver body 42, and an electric screwdriver bit 43. The slider 41 is slidably mounted on the lifting block 33, the electric screwdriver body 42 is mounted on the slider 41, and one end of the electric screwdriver bit 43 passes through the suction nozzle 34. The electric screwdriver body 42 is used to drive the electric screwdriver bit 43 to rotate. Optionally, the electric screwdriver bit 43 is provided with a sealing ring, which is used to seal the electric screwdriver bit 43 and the suction nozzle 34. In one embodiment, the electric screwdriver body 42 and the electric screwdriver bit 43 are existing technologies. Further, the screw-driving assembly 40 also includes a slide rail 44 and a telescopic power element 45. Both the slide rail 44 and the telescopic power element 45 are mounted on the lifting block 33, the slider 41 is slidably mounted on the slide rail 44, and the telescopic power element 45 is used to drive the slider 41 to slide.

[0034] In use, the transverse block 32 slides to the feeder, which arranges the screws sequentially. The feeder is existing technology. The lifting block 33 then descends until the suction nozzle 34 abuts against the screw. At this time, the vacuum pump draws air, causing the suction nozzle 34 to pick up the screw. During the material picking process of the suction nozzle 34, the hardware accessory 90 is manually placed on the carrier 21. At this time, the panel 91 is accommodated in the groove 202, and the sound-emitting component is accommodated in the receiving cavity 201. Then, the metal cover 80 is placed on the hardware accessory 90. The end face of the metal cover 80 abuts against the carrier 21, the side of the metal cover 80 abuts against the inner side of the limiting block 22, and the periphery of the metal cover 80 abuts against the top of the limiting block 22. The positioning block 26 is inserted into the clearance hole 81. At this time, the stud 92 passes through the insertion hole. 82. Through hole 83 connects to threaded hole 911. Then, flip block 23 flips, so that pressure block 25 presses metal cover 80. Next, carrier 21 slides to the first screw-on station. At the same time, after suction nozzle 34 picks up the material, lifting block 33 rises again, and transverse block 32 slides to the unloading position. Then, lifting block 33 falls again until the screw is inserted into through hole 83. At the same time, electric screwdriver body 42 drives electric screwdriver head 43 to rotate, vacuum pump stops working, telescopic power element 45 drives slider 41 to fall, so that electric screwdriver head 43 passes through suction nozzle 34. Then, electric screwdriver head 43 inserts screw into through hole 83 and threaded hole 911, so that screw and threaded hole 911 are threadedly connected, thereby assembling hardware accessories 90 onto metal cover 80.

[0035] After assembly is complete, the electric screwdriver bit 43 stops rotating, the slider 41 rises, the lifting block 33 rises, and the lateral block 32 moves laterally to the feeder to repeat the screw-picking operation. At the same time, the carrier 21 slides to the second screw-on station, which corresponds to two threaded holes 911 on the same horizontal line. The suction nozzle 34 and the electric screwdriver bit 43 then cooperate to insert the screw into the through hole 83 and the threaded hole 911. After all three screws are assembled on the metal cover 80 and the hardware accessories 90, the flipping block 23 flips, causing the pressure block 25 to move away from the metal cover 80, and the assembled workpiece is removed manually.

[0036] The automatic screw-driving device 100 for metal caps and hardware accessories of this utility model is provided by hardware accessories 90 being housed in receiving cavity 201, limiting block 22 supporting metal cap 80, and pressing block 25 abutting against metal cap 80 to press metal cap 80 tight and prevent metal cap 80 from shifting.
