Please refer to Figure 1 , Figure 2 and Figure 3 , an automated inspection system, comprising a robot arm 3 and a secondary positioning mechanism 2, wherein the robot arm 3 is connected to a first two-finger gripper 5. The robot arm 3 may be a commercially available Elite EC63 robot arm 3. The secondary positioning mechanism 2 comprises a positioning platform 22 and a second two-finger gripper 21. When the first two-finger gripper 5 clamps the moving workpiece 7 onto the positioning platform 22, the clamping trajectory of the first two-finger gripper 5 is perpendicular to the clamping trajectory of the second two-finger gripper 21, and the clamping trajectory of the first two-finger gripper 5 and the clamping trajectory of the second two-finger gripper 21 are both parallel to the placement plane of the positioning platform 22.

[0020] Specifically, while the first two-finger gripper 5 grips the workpiece 7, it positions the workpiece 7 in the direction of the gripping track of the first two-finger gripper 5. The secondary positioning mechanism 2 positions the workpiece 7 in the direction of the gripping track of the second two-finger gripper 21 through the second two-finger gripper 21. The first two-finger gripper 5 and the second two-finger gripper 21 cooperate to completely position the horizontal position of the workpiece 7, ensuring that the workpiece 7 is accurately placed in the detection position, and cooperate with the detection device 6 to realize automated detection and improve detection efficiency.

[0021] The specific structure of the secondary positioning mechanism 2 is described below:

[0022] Please refer to Figure 2 The secondary positioning mechanism 2 also includes a sensor 23, which is aligned with the placement plane of the positioning platform 22. The sensor 23 can be a commercially available Boyi KGS-19-2L photoelectric sensor 23. After the sensor 23 detects that the workpiece 7 moves to the positioning platform 22, it transmits an electrical signal to start the second two-finger gripper 21 for positioning, ensuring that the secondary positioning is carried out smoothly.

[0023] Please refer to Figure 1 and Figure 2 The sensor 23 is arranged on the mounting surface through a connecting plate 231, and a through slot 232 is vertically provided on the connecting plate 231. The sensor 23 is connected to the connecting plate 231 through bolts (not shown in the figure), and the position of the bolts is adjusted along the through slot 232 to conveniently adjust the position of the sensor 23. The secondary positioning mechanism 2 also includes a protective cover 24, which is arranged around the second two-finger clamp 21 and the positioning platform 22 to prevent foreign matter from entering and affecting the accuracy of the secondary positioning.

[0025] Please refer to Figure 1 , and also includes a detection device 6, which is arranged in the working area of ​​the robot arm 3, and the robot arm 3 places the workpiece 7 to be detected at the detection position. The detection device 6 can be various material detection equipment known in the art, for example, the detection device 6 can be a commercially available ZVHBS-300AET hardness tester, and the workpiece 7 is placed at the detection position by the robot arm 3, and after the detection is completed, it is removed by the robot arm 3, so as to realize automatic detection.

[0026] Please refer to Figure 1 , and also includes a material rack 1, on which a material tray 11 and a waste tray 12 are arranged. The workpieces 7 are moved into the loading position of the robot arm 3 in batches through the material tray 11 to improve the transfer efficiency. The number of the material trays 11 is two or more, so as to alternately load and unload materials and improve the detection efficiency.

[0027] The specific structure of the robot arm 3 is described below as follows

[0028] A rotating seat 51 is provided between the robot arm 3 and the first two-finger gripper 5, and two first two-finger grippers 5 are provided on the rotating seat 51. When the robot arm 3 removes the workpiece 7 after inspection, it can pre-clamp a workpiece 7 to be inspected, so that after removing the workpiece 7, the rotating seat 51 can be rotated to quickly place the workpiece 7 to be inspected at the inspection position, thereby increasing the speed of loading and unloading.

[0029] The robot arm 3 is provided with a cable tie mechanism 4, which includes a fixing ring 41 connected to the robot arm 3 and a cable tie ring 42 connected to the fixing ring 41. The pipes and lines are restrained to avoid entanglement. At least three cable tie mechanisms 4 are provided on the robot arm 3 to cooperate with the multiple bending of the robot arm 3 and synchronously twist the pipes and lines.

[0030] The specific working process of the utility model is as follows:

[0031] The robot arm 3 moves the first two-finger gripper 5 to the position for gripping the material, the first two-finger gripper 5 closes to grip the workpiece 7, and positions the workpiece 7 in the direction of the gripping track of the first two-finger gripper 5. The robot arm 3 moves the first two-finger gripper 5 to the position for secondary positioning, the first two-finger gripper 5 places the workpiece 7 on the positioning platform 22. The second two-finger gripper 21 closes to grip the workpiece 7, and positions the workpiece 7 in the direction of the gripping track of the second two-finger gripper. The first two-finger gripper re-grips the workpiece 7, and the horizontal position of the workpiece 7 is now completely positioned. The robot arm 3 moves the first two-finger gripper 5 to the detection position and positions the workpiece 7, and removes the workpiece 7 after the detection is completed, completing the detection of the workpiece 7.
