[0048] Specifically, the second loading assembly 5 also includes a first positioning assembly 52, which is arranged at the bottom of the bearing rail 511.

When the workpiece to be installed moves to the first positioning assembly 52, the bearing rail 511 stops moving, and the first driving member 521 controls the positioning pin 522 to plug into the workpiece to be installed through the first driving rod, so as to ensure that the position of the workpiece to be installed is fixed during the tightening of the data screw.

[0049] It should be noted that there can be multiple first positioning components 52, and multiple first positioning components 52 can be arranged side by side along the length direction of the supporting rail 511. When the positioning pin 522 of the first positioning component 52 is in a disengaged position from the workpiece to be installed, the second loading component 5 moves normally and the automatic tightening equipment operates normally. When the positioning pin 522 of the first positioning component 52 is in a plug-in position with the workpiece to be installed, the driving part stops driving and the second loading component 5 stops moving to stabilize the workpiece to be installed.

[0050] Specifically, the second loading assembly 5 also includes a second positioning assembly 53, which is arranged on the top of the loading bracket 51. The second positioning assembly 53 includes: a second driving member 531 and a limiting rod 532.

When the workpiece to be installed moves to the second positioning assembly 53, the bearing rail 511 stops moving, and the second driving member 531 drives the second driving rod to abut against the workpiece to be installed through the limiting rod 532 to limit the workpiece to be installed. At the same time, according to the different types of information of the workpiece to be installed that are identified, the positions of different types of workpieces are located to facilitate the subsequent grasping and tightening operations of the workpiece to be installed.

[0051] Specifically, the second loading component 5 also includes: a code reader 54, a first induction switch 55 and a second induction switch 56.

In this arrangement, the first sensing switch 55 and the second sensing switch 56 sense that the workpiece to be installed is located at different positions in the second loading component 5, so as to perform signal control on the first positioning component 52 and the second positioning component 53, so that the second loading component 5 stops at a preset position, and performs corresponding identification and positioning operations on the workpiece. When the workpiece to be installed reaches the first sensing switch 55, the driving unit stops driving, and the installation work stops at the position. The QR code on the workpiece to be installed is scanned and read by the code reader 54 to obtain the model information of the workpiece to be installed.

At the same time, the driving assembly drives the tightening assembly to move to the first feeding assembly to absorb the data screw on the grabbing mechanism.

[0054] A baffle 221 is disposed at the end of the linear channel 22 to prevent the data screw from sliding off the end of the linear channel 22 .

[0055] Furthermore, the tightening assembly 4 includes: a mounting plate 41, a tightening shaft 42 and an air slip ring 45; the tightening shaft 42 is connected to the mounting plate 41, and a vacuum adsorption portion is provided at the execution end of the tightening shaft 42; the rotor of the air slip ring 45 is connected to the tightening shaft 42, and the air slip ring 45 is used to drive the tightening shaft 42 to rotate around the axis of the tightening shaft 42. This arrangement can realize the automatic tightening operation of the data screw.

[0056] It should be noted that after the vacuum adsorption part adsorbs the data screw, it can be equipped with an air compression bag of a certain capacity to avoid the risk of the data screw falling due to large fluctuations in air pressure.

[0057] In one embodiment of the present application, according to the identified data screw type, the rotating module 34 of the tightening assembly 4 is controlled to rotate to different angles, and then the first sliding module 31, the second sliding module 32 and the third sliding module 33 are controlled to perform position fine-tuning. After reaching the precise tightening position, the vacuum adsorption part of the tightening shaft 42 is started, and after passing the test, it is closed, and the equipment returns to its original position.

[0058] Specifically, the tightening assembly 4 further includes a third driving member 44, the third driving member 44 is connected to the mounting plate 41, the tightening shaft 42 is connected to a third driving rod of the third driving member 44, and the third driving rod drives the tightening shaft 42 to move along the axial direction of the tightening shaft 42.

[0059] Specifically, the tightening assembly 4 further includes a sleeve 43, which is connected to the execution end of the tightening shaft 42, and the vacuum adsorption part is located in the sleeve 43.

[0060] Specifically, the tightening assembly 4 also includes a pressure detection gauge 46, which is arranged on the tightening shaft 42. The pressure detection gauge 46 is connected to the vacuum adsorption part signal and is used to detect the pressure of the vacuum adsorption part. This arrangement facilitates the detection and judgment of the operation progress of the tightening assembly 4 by the pressure value of the vacuum adsorption part. When the pressure detection gauge 46 detects that the vacuum adsorption is qualified, the data screw has entered the sleeve 43, indicating that this operation has been completed.

[0061] This application specifically solves the above problems through the following operating steps of the automatic tightening device:

[0062] Specifically, clean the surface of the data screws, put a certain number of data screws into the first loading component 2 of the automatic tightening device, and manually return the device to its original position. After starting the equipment, the second loading component 5 extends out. When the workpiece to be installed reaches the first sensing switch 55, the first positioning component 52 drives the positioning pin 522 to be plugged into the workpiece to be installed through the first driving member 521, and the code reader 54 is started to take pictures to identify the two-dimensional code information at the front end of the workpiece to be installed. The two-dimensional code information includes information such as the workpiece type and the workpiece serial number. After the code reader 54 reads successfully, the first positioning component 52 drives the positioning pin to release the workpiece to be installed. When the workpiece to be installed reaches the second sensing switch, the second positioning component 53 drives the limit rod 532 to abut the workpiece to be installed through the second driving member 531 to limit the position of different types of workpieces. After starting the equipment, the data screw is transported to the linear material channel 22. The third sensing switch 26 located at the front of the linear material channel 22 determines that there is a data screw at the current position. The rotating cylinder 23 rotates an angle, the lifting cylinder 24 descends, and the grasping part grasps the data screw and returns to its original position, waiting for the first sliding module 31 of the tightening component 4 to move to the data screw position.

[0063] The tightening component 4 has the ability to move in three-dimensional directions and rotation. According to the type of workpiece, the rotating module 34 is controlled to rotate a certain angle, and the first sliding module 31, the second sliding module 32 and the third sliding module 33 are controlled to fine-tune the position to reach the precise tightening position. The tightening shaft 42 is started to tighten, and the vacuum adsorption is turned on. After the pressure detection gauge detects that the vacuum adsorption is qualified, it means that the data screw has entered the sleeve, the vacuum adsorption valve is closed, and the drive component 3 returns to its original position.

[0064] If an abnormal situation occurs during the operation of the equipment, an alarm message will be given on the HMI panel to prompt the operator or maintenance personnel how to deal with the current fault.

[0065] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:
