[0028] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0029] like Figures 1 to 12As shown, this utility model discloses a workpiece inspection mechanism, which includes a frame 1. A vibratory feeder 2 is mounted on the frame 1, and a workpiece positioning component 4 for positioning a workpiece 3 is mounted at the discharge end of the vibratory feeder 2. A first workpiece inspection component 5, a second workpiece inspection component 6, and a receiving component 7 are sequentially arranged along the feeding direction on one side of the workpiece positioning component 4. A first workpiece inspection positioning component 8 and a second workpiece inspection positioning component 9 are respectively arranged on one side of the first workpiece inspection component 5 and the second workpiece inspection component 6 to position the workpiece 3 for inspection. A defective product receiving component (as shown in the figure) is provided between the first workpiece inspection positioning component 8 and the second workpiece inspection positioning component 9, and between the second workpiece inspection positioning component 9 and the receiving component. The defective product receiving component is a receiving box used to receive workpieces 3 that fail the inspection. The first workpiece detection and positioning component 8, the second workpiece detection and positioning component 9, and the receiving component 7 are all equipped with a moving device 10 for transporting workpieces 3. The moving device 10 is equipped with gripper components 11 corresponding to the first workpiece detection and positioning component 8, the second workpiece detection and positioning component 9, and the receiving component 7. In use, the workpiece 3 is placed from the discharge end of the vibratory feeder 2 into the workpiece positioning component 4 for positioning, facilitating the gripper components 11 to grasp the workpiece 3. The moving device 10 drives the gripper components 11 to move, sequentially transporting the workpiece 3 to the first workpiece detection and positioning component 8 and the second workpiece detection and positioning component 9. The first workpiece detection component 5 and the second workpiece detection component 6 are used to detect the workpiece 3. After detection, the workpiece 3 is collected by the receiving component 7. The vibratory feeder 2 of this invention belongs to the existing structure in this field, and its functionality is considered to be achieved.
[0030] The workpiece positioning assembly 4 includes a positioning seat 41, a positioning groove 42 disposed on the positioning seat 41, and a positioning rod 43 penetrating the positioning groove 42. The positioning rod 43 is threadedly connected to the positioning groove 42 to facilitate adjustment of the size of the positioning groove 42 and facilitate the positioning of the workpiece 3. A through groove 44 is provided on the positioning groove 42 for the gripper assembly 11 to grasp the workpiece 3. A lifting device 45 is provided below the positioning seat 41 to move the positioning seat 41 and the positioning groove 42 vertically.

Below the first base 81 are a Z-axis angle moving slide 83 and a first X-axis angle moving slide 84 for adjusting the angle of the first base 81. The first X-axis angle moving slide 84 is located below the Z-axis angle moving slide 83.

In use, the first camera 51, the second camera 52, the third camera 53, the fourth camera 54, and the fifth camera 55 respectively inspect the dimensions and appearance of different surfaces of the workpiece 3. If the inspection result is a defective product, the gripper 111 is released when the workpiece 3 passes through the defective product receiving assembly, allowing the workpiece 3 to fall into the defective product receiving assembly.
[0034] Furthermore, the second workpiece detection and positioning assembly 6 includes an adjustable second base 61, on which a second locking block 62 for positioning the workpiece 3 is provided.

The straight line containing the horizontal light source 93 and the prism 95 is perpendicular to the straight line containing the prism 95 and the sixth camera 94. The prism 95 can overcome the limitations of the workpiece detection space and improve space utilization. The laser sensor 91 is disposed on an adjustable height adjustment platform 97, which has an elongated hole for adjusting the height of the laser sensor 91. Below the adjustment platform 97 are a Y-axis linear motion slide 98 and an X-axis linear motion slide 99, with the X-axis linear motion slide 99 located below the Y-axis linear motion slide 98.
[0035] The laser sensor 91, the second vertical light source 92 and the horizontal light source 92, the sixth camera 94 and the seventh camera 96 are used to detect the size and appearance of different surfaces of the workpiece 3. If the detection result is a defective product, the gripper 111 is released when the workpiece 3 passes through the defective product receiving assembly, allowing the workpiece 3 to fall into the defective product receiving assembly.
[0036] The X-axis moving device 12, the first Z-axis moving device 13, the second Z-axis moving device 15, the first X-axis angle moving slide 84, the Z-axis angle moving slide 83, the second X-axis angle moving slide 63, the X-axis linear moving slide 99, and the Y-axis linear moving slide 98 of this utility model are all connected to a driving device to drive their operation.

The lifting device drives the workpiece positioning component 4 to rise and fall, making the positioning groove 42 parallel to the discharge end of the vibratory feeder, so that the workpieces 3 fall into the positioning groove 42 in sequence to wait for the gripper component 11 to pick them up. The moving device 10 drives the gripper component 11 to pick up the workpiece 3 and move it to the first workpiece detection and positioning component 8. The first workpiece detection component 5 performs visual inspection on the size and different surfaces of the workpiece. If the workpiece 3 is unqualified, it is moved to the defective product receiving component. If the workpiece 3 is qualified, the moving device moves the workpiece 3 to the second workpiece detection and positioning component 9. The second workpiece detection component 6 performs visual inspection on the size and different surfaces of the workpiece. If the workpiece 3 is unqualified, it is moved to the defective product receiving component.
