[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0033] Example

[0034] like Figure 1-9 As shown, a fully automatic screw driving machine includes a shell 1, a driving component 2 fixedly mounted on the shell 1, a sliding frame 3 arranged at the lower end of the front side of the shell 1, a first swing arm 4 whose upper end is hingedly mounted to the shell 1 and whose lower end is fixedly mounted to the sliding frame 3, a nailing component 5 installed at one end of the sliding frame 3, and a second swing arm 6 located above the sliding frame 3, wherein one end of the second swing arm 6 is hingedly mounted to the shell 1 and the other end is movably mounted to the nailing component 5.

[0035] It should be further explained that the housing 1 and internal components such as the drive component 2, the sliding frame 3, the first swing arm 4 and the second swing arm 6 are compactly designed, effectively utilizing the limited space, so that the overall equipment occupies a small area and is suitable for various working environments.

[0036] The housing 1 is provided with a first swing arm assembly hole 11 , a drive motor assembly hole 12 and a second swing arm assembly hole 13 in sequence from top to bottom. Two support blocks 14 for assembling the sliding frame 3 are fixed to the lower front end of the housing 1 .

[0037] The driving assembly 2 includes a driving motor 21 fixedly mounted on the back of the housing 1, and a disc 22 fixedly mounted on the output end of the driving motor 21 and located on the front of the housing 1. The inner side surface of the disc 22 is provided with a protrusion 221 that contacts the first swing arm 4, and the outer side surface of the disc 22 is provided with a guide groove 222 that cooperates with the second swing arm 6.

[0038] In the structure of the disc 22 , the protrusion 221 is arranged in a semicircle. Specifically, when the driving motor 21 drives the disc 22 to rotate, the first swing arm 4 can be lifted up by the protrusion 221 , so that the first swing arm 4 can swing left and right.

[0039] In the structure of the disc 22, the guide groove 222 includes a lifting section 222a and a pressing section 222b. Specifically, when the driving motor 21 drives the disc 22 to rotate, when the pressing section 222b contacts the second swing arm 6 due to the rotation of the disc 22, the second swing arm 6 is pressed down due to the guidance of the pressing section 222b, so that the nailing assembly 5 moves downward, and when the lifting section 222a contacts the second swing arm 6 due to the rotation of the disc 22, the second swing arm 6 is lifted due to the guidance of the lifting section 222a.

[0040] It should be further explained that the driving assembly 2 includes a driving motor 21 and a disc 22, and the disc 22 is driven to rotate by the power provided by the driving motor 21. The protrusion 221 on the inner side of the disc 22 contacts the first swing arm 4, and the guide groove 222 on the outer side cooperates with the second swing arm 6. This design can effectively transmit power and control the action, thereby improving the stability and accuracy of the operation. The first swing arm 4 and the second swing arm 6 are hingedly mounted on the housing 1 so that they can move according to a predetermined path and speed. The protrusion 221 and the guide groove 222 of the disc 22 ensure the correct position and movement trajectory of the first swing arm 4 and the second swing arm 6, thereby accurately controlling the action of the nailing assembly 5.

[0041] The sliding frame 3 includes two steel columns 31 parallel to each other, an anti-dropping block 32 fixedly installed at one end of the two steel columns 31, a connecting block 33 fixedly installed at the other end of the two steel columns 31 and movably assembled with the nailing assembly 5, and a clamping block 34 fixedly installed on the two steel columns 31 and assembled with the first swing arm 4. Specifically, the two steel columns 31 pass through the two support blocks 14, and the clamping block 34 is driven by the first swing arm 4 to enable the two steel columns 31 to move laterally between the two support blocks 14.

[0042] The first swing arm 4 includes a first swing arm assembly head 41, a first swing arm shaft 42 inserted into the first swing arm assembly head 41, a first swing arm rod 43 fixedly installed with the first swing arm shaft 42, and a first swing arm rod rotating wheel 44 fixedly installed at the center of the first swing arm rod 43; specifically, the first swing arm rod rotating wheel 44 contacts with a semicircular protrusion 221 arranged on the back of the disc 22, and the first swing arm rod rotating wheel 44 is lifted up by the protrusion 221, so that the first swing arm 4 drives the clamping block 34 to make the two steel columns 31 move laterally between the two support blocks 14.

[0043] In the structure of the first swing arm 4, the end of the first swing arm shaft 42 that contacts the first swing arm rod 43 is welded with a first swing arm shaft assembly disk 421, and the end of the first swing arm rod 43 that contacts the first swing arm shaft assembly disk 421 is integrally formed with a first swing arm fixed end 431, and the other end of the first swing arm rod 43 is provided with a first swing arm rod hinge hole 432. Specifically, the first swing arm rod 43 is assembled with the clamping block 34 through the first swing arm rod hinge hole 432.

[0044] The nailing assembly 5 includes a nailing bracket 51, two vertical rods 52 welded above the nailing bracket 51, a limit block 53 fixedly installed above the two vertical rods 52, a limit stud 54 fixedly installed on the limit block 53 and capable of being assembled with the second swing arm, a nailing motor 55 fixedly installed on the nailing bracket 51, and a magnetic sleeve 56 sleeved on the output end of the nailing motor 55 and fixedly installed with the nailing bracket 51 by bolts.

[0045] It should be further explained that the nailing bracket 51 provides a stable support platform to ensure stability and accuracy during the nailing process. The fixation of the two vertical rods 52 and the limit block 53 enhances the rigidity of the overall structure and helps to reduce vibration and error. The limit stud 54 is fixed on the limit block 53 and can be assembled with the specific position of the second swing arm to ensure the accuracy and repeatability of the nailing action. This design ensures that the position of each nailing is within the predetermined range and is suitable for nailing tasks that require high precision.

[0046] In the structure of the nailing assembly 5, a U-shaped holder 511 is provided on the side of the nailing bracket 51 where the nailing motor 55 is assembled, and a U-shaped assembly opening 512 is provided at the lower end of the nailing bracket 51 where the nailing motor 55 is assembled. Specifically, the nailing motor 55 is fixedly installed by assembling it on the U-shaped holder 511;

[0047] In the structure of the nailing assembly 5, a detachable screwdriver 551 is fixedly installed at the output end of the nailing motor 55. Specifically, the screwdriver 551 passes through the U-shaped assembly port 512 and the magnetic sleeve 56 in sequence. By energizing the magnetic sleeve 56, the coil inside the magnetic sleeve 56 has a sufficiently strong magnetic field, so that the screwdriver 551 generates a magnetic attraction screw, which is then transferred to the component that needs to be nailed, and then the nailing motor 55 is started to drive the screwdriver 551 to complete the nailing.

[0048] The second swing arm 6 includes a second swing arm assembly head 61, a second swing arm shaft 62 inserted into the second swing arm assembly head 61, a second swing arm rod 63 fixedly installed with the second swing arm assembly head 61, and a second swing arm rod rotating wheel 64 fixedly installed at the center of the second swing arm rod 63; specifically, the second swing arm rod rotating wheel 64 is embedded in the guide groove 222 on the front side of the disc 22, and when the disc 22 rotates, the guide groove 222 is used to control the second swing arm rod 63 to lift or press down the nailing assembly 5.

[0049] The end of the second swing arm shaft 62 that contacts the second swing arm rod 63 is welded with a second swing arm shaft assembly disk 621, and the end of the second swing arm rod 63 that contacts the second swing arm shaft assembly disk 621 is integrally formed with a second swing arm fixed end 631, and the other end of the second swing arm rod 63 is provided with a second swing arm rod strip hole 632. Specifically, the second swing arm rod 63 is assembled with the limiting stud 54 through the second swing arm rod strip hole 632, and provides a movable stroke space.

[0050] Therefore, when the driving motor 21 rotates the disc 22, not only can the first swing arm lever wheel 44 be lifted up by the semicircular protrusion 221 arranged on the back of the disc 22, so that the first swing arm 4 drives the clamping block 34 to make the two steel columns 31 move laterally between the two support blocks 14, but also the second swing arm 6 can be driven by the guide groove 222 on the front side of the disc 22 to control the second swing arm lever 63 to lift or press down the nailing assembly 5.

[0051] It should be further explained that the movable travel space of the second swing arm bar hole 632 is larger than the movable travel space of the sliding frame 3 between the two support blocks 14, which can improve the matching degree between the disc 22 and the first swing arm 4 and the second swing arm 6.

[0052] like Figure 10-11 As shown, at this time, the disc 22 controls the first swing arm 4 and the second swing arm 6 to be linked, and the first swing arm 4 controls the sliding frame 3 to be in balanced sliding, and the second swing arm 6 controls the nailing assembly 5 to lift, and the screws are transported or the nailing assembly 5 is reset to magnetically absorb the screws for transportation.

[0053] like Figure 12-13 As shown, at this time, the disc 22 controls the first swing arm 4 and the second swing arm 6 to work in conjunction, and controls the nailing assembly 5 to press down and drive the screw through the second swing arm 6.

[0054] like Figure 14-15 As shown, at this time, the disc 22 controls the first swing arm 4 and the second swing arm 6 to work in conjunction, and controls the nailing assembly 5 to press down the magnetic screw through the second swing arm 6.

[0055] The above embodiments of the present invention are not intended to limit the protection scope of the present invention, and the implementation modes of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in the art, without departing from the above basic technical ideas of the present invention, should fall within the protection scope of the present invention.
