By setting the Y transfer assembly 12 and the receiving platform assembly 13, the workpiece can be automatically transported to the locking area below the screw machine head assembly 8 for locking after installation, and reset after the locking is completed. A plurality of anti-slip assemblies 14 are fixedly installed on the top wall of the frame 1. Through the setting of the anti-slip assembly 14, the receiving platform assembly 13 is positioned after moving to avoid a small range of sliding during the locking process, which has a certain impact on the locking accuracy.

[0025] The screw machine head assembly 8 includes a mounting block 81 slidably connected to the side wall of the second connecting plate 7 and a locking machine body 82 fixedly connected to the side wall of the mounting block 81. A connecting rod 83 is fixedly connected to the bottom surface of the mounting block 81, and a first support plate 84 is fixedly connected to the bottom end of the connecting rod 83. The screw machine head assembly 8 can rotate and descend during operation to screw the screw into the workpiece.

[0026] Slide grooves 91 are provided on the side walls on both sides of the positioning block 9 , and a plurality of limiting holes 911 are provided on the inner cavity side wall of each slide groove 91 .

[0027] The glue dispensing component 11 includes two connecting parts 111 which are respectively slidably connected inside the two slide grooves 91. The two connecting parts 111 are commonly fixedly connected to a piston cylinder 112. The piston cylinder 112 has a piston built in it (not shown in the figure), and its rodless cavity is filled with screw glue. A glue dispensing head 113 is fixedly connected to the bottom surface of the piston cylinder 112, and a piston rod 114 is slidably connected to the top surface of the piston cylinder 112. The top ends of the two piston rods 114 are commonly fixedly connected to a second support plate 115, and the bottom surface of the second support plate 115 and the top surface of the piston cylinder 112 are elastically connected via a first spring 116.

[0028] In this embodiment: after the workpiece moves to the locking area below the screw head assembly 8, the position of the screw head assembly 8 is adjusted by the X transfer assembly 3 and the Z transfer assembly 6, so that the bottom opening part of the feeding head 10 for screw feeding is aligned with the threaded hole of the workpiece, and then the locking machine body 82 is started to rotate and descend to lock the screw. During the descent, the mounting block 81 drives the first abutment plate 84 to move synchronously through the connecting rod 83 at the bottom, and the first abutment plate 84 abuts against the second abutment plate 115 to squeeze out the screw glue in the rodless cavity of the piston cylinder 112, and glue is applied to the screws that need glue, thereby meeting the locking requirements of some workpieces.

[0029] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 4-Figure 5 A clamping groove 131 is symmetrically provided on the side wall of the receiving platform component 13, and the receiving platform component 13 is used to install and fix the workpiece.

[0030] Each anti-slip component 14 includes two limit blocks 141 fixedly connected to the top surface of the frame 1, and the two limit blocks 141 are symmetrically arranged on both sides of the Y transplant component 12. A groove 1411 is opened on the side wall of each limit block 141, and a second spring 142 is fixedly connected inside each groove 1411. One end of each second spring 142 is fixedly connected to a locking ball 143, and the locking ball 143 is slidably arranged inside the groove 1411. The opening area of ​​the groove 1411 is smaller than the area of ​​the cross section inside it, so that the locking ball 143 will not slide out of the groove 1411.

[0031] In this embodiment: when the receiving platform component 13 moves into place, the locking ball 143 on the side wall of the anti-slip component 14 is embedded in the locking groove 131 and is tightened by the elastic force of the second spring 142, so that the receiving platform component 13 will not slide easily, avoiding instability of the workpiece when the screw is tightened, which affects the tightening accuracy.

[0032] Working principle: When in use, the operator fixes the workpiece on the receiving platform component 13, and then starts the Y transfer component 12 to move it to the locking area below the screw head component 8. At this time, the receiving platform component 13 is positioned by the anti-slip component 14, and then the position of the screw head component 8 is adjusted by the X transfer component 3 and the Z transfer component 6 to align it with the threaded hole that needs to be locked. After the screw is delivered to the position through the loading head 10, the locking machine body 82 is started, which locks the corresponding screw by rotating and descending; when part of the workpiece needs to be glued and locked with screws, the sliding connection 111 drives the piston cylinder 112 to slide, so that the second push plate 115 and the first push plate 84 are on the same vertical line. When the first push plate 84 is pressed down, it can drive the second push plate 115, and then the piston rod 114 can drive the piston inside the piston cylinder 112 (not shown in the figure), squeeze out the screw glue and perform glue dispensing operation on the screw.
