[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1-5An auxiliary screw-driving mechanism shown includes a support frame 1, an auxiliary mechanism is arranged on the front of the support frame 1, the auxiliary mechanism includes a movable plate 2, a screw gun guide mechanism 7 and a limit assembly, the movable plate 2 is movably arranged on the front of the support frame 1, and a rotating assembly for the movement of the movable plate 2 is arranged between the movable plate 2 and the support frame 1, the screw gun guide mechanism 7 is fixedly arranged on the top of the movable plate 2, the screw gun guide mechanism 7 is used for tightening the screws, the limit assembly is arranged between the movable plate 2 and the support frame 1, and the limit assembly is used to limit the position of the movable plate 2.

[0024] Specific reference Figure 1 and Figure 2 When in use, the movable plate 2 can be rotated at different angles according to the placement position of the screw, so that it can adapt to screw tightening at various positions and angles. The screw gun guide mechanism 7 fixedly arranged on the movable plate 2 can tighten the screw after the position of the movable plate 2 is adjusted. The screw gun guide mechanism 7 includes a guide hole and a screw gun. The position of the screw can be limited by the guide hole, and then the screw gun can tighten the screw through the guide hole. In this process, the screw range can be limited, and the phenomenon of tilting during the screw tightening process can be avoided, which effectively improves the stability of the screw tightening, thereby enhancing the accuracy and effect of the screw tightening.

[0025] The auxiliary mechanism also includes a screw pressing block 8, which is fixedly arranged at the bottom end of the movable plate 2. The screw pressing block 8 is used to limit the position of the fixed object. The top end of the screw pressing block 8 passes through the top end of the movable plate 2 and extends upward. The outer wall of the screw pressing block 8 is provided with a nut.

[0026] Specific reference Figure 3 and Figure 4 The screw pressing block 8 is fastened to the movable plate 2 by a nut sleeved on the outside. The screw pressing block 8 rotates with the rotation of the movable plate 2. Through the setting of the screw pressing block 8, the fastened product can be squeezed, so that when the screw gun guide mechanism 7 is used to tighten the screw, the accuracy of the screw fastening position on the product can be ensured, thereby enhancing the effectiveness of the auxiliary screw driving process.

[0027] The rotating assembly includes a rotating shaft 3 and a sensor. The rotating shaft 3 is fixedly interlaced with one end of the movable plate 2, and one end of the rotating shaft 3 is movably interlaced with the support frame 1. The sensor is located on one side of the support frame 1 and at one end of the rotating shaft 3. The sensor includes two proximity sensors 5. The two proximity sensors 5 are fixedly arranged on one side of the support frame 1. The proximity sensors 5 are used to detect the rotation angle of the movable plate 2.

[0028] Specific reference Figure 1 and Figure 3The setting of the rotating shaft 3 enables the movable plate 2 to be directly and movably connected to the support frame 1, and the rotation of the rotating shaft 3 can drive the movable plate 2 to rotate synchronously, thereby improving the flexibility of the rotation of the movable plate 2. The setting of the proximity sensor 5 can detect whether the rotation position is accurate when the movable plate 2 rotates, thereby ensuring the accuracy and effectiveness of the rotation of the movable plate 2, and at the same time enhancing the firmness and effect of the screw tightening.

[0029] The limiting assembly includes a positioning plate 4 and a positioning cylinder 6 . The positioning plate 4 is fixedly arranged on the top of the movable plate 2 . The positioning cylinder 6 is fixedly arranged on the top of the support frame 1 and is located on one side of the positioning plate 4 .

[0030] Please refer to the details Figure 1 and Figure 5 The coordination of the positioning plate 4 and the positioning cylinder 6 enables the positioning cylinder 6 to penetrate into the position of the positioning plate 4 by starting the positioning cylinder 6 after the movable plate 2 rotates. A latch hole is provided on the outer wall of the positioning plate 4, and the output shaft of the positioning cylinder 6 is inserted into the latch hole to limit the positioning plate 4, thereby enabling the movable plate 2 to be fixed in position. Conversely, when the movable plate 2 needs to be rotated, the positioning cylinder 6 is driven in the reverse direction, and the movable plate 2 can be released after being separated from the positioning plate 4.

[0031] As described above, the overall working principle is to first rotate the rotating shaft 3 so that the rotating shaft 3 drives the movable plate 2 to rotate, so that the movable plate 2 rotates to an angle that meets the installation screw, and start the positioning cylinder 6 so that the output shaft of the positioning cylinder 6 extends out and inserts into the pin hole of the positioning plate 4, thereby limiting the position of the movable plate 2. At the same time, the screw pressing block 8 protrudes from the movable plate 2, which can press and fix the product, and then the screw gun guide mechanism 7 is used to tighten the screw to the product at the corresponding position.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
