When the conveyor belt 102 transports the rivet part 207 to the bottom of the detection component 103, the industrial camera of the detection component 103 analyzes the rivet part 207, and the unqualified rivet part 207 is removed by the material removal mechanism on the conveyor belt 102.

[0034] Operation process: The conveyor belt 102 circulates to transport the rivet parts 207. When the conveyor belt 102 transports the rivet parts 207 to the bottom of the detection component 103, the industrial camera of the detection component 103 analyzes the rivet parts 207. The unqualified rivet parts 207 are removed by the removal mechanism on the conveyor belt 102, and the qualified rivet parts 207 are transported to the end of the conveyor belt 102 and dropped for storage, thereby completing the sorting of the rivet parts 207.

[0035] Example 2

[0036] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the sorting unit 200 includes a positioning component 201 arranged on the conveyor belt 102, the positioning component 201 is used to place the fallen rivet pieces 207, so that the brim of each group of rivet pieces 207 to be detected is kept at the same position at the detection point, a storage box 202 is installed on the top of the frame 101, the storage box 202 is used to store the rivet pieces 207, a feeding component 203 is installed inside the storage box 202, and a vibration component 204 is arranged on the feeding component 203, and the vibration component 204 is used to stack the The rivet piece 207 is successfully matched with the running groove 203d of the custom wheel 203c and the brim groove 203e. The blanking assembly 205 arranged on the storage box 202, the partition assembly 206 arranged on the blanking assembly 205, and the rivet piece 207 arranged in the storage box 202 can be stacked in the storage box 202 with the same orientation. The partition assembly 206 separates the rivet pieces 207 at the end of the sliding groove 203f, so that after the rivet piece 207 at the blanking port 205a falls down, the partition assembly 206 can replenish a new group of rivet pieces 207.

[0037] Specifically, the positioning assembly 201 includes a positioning seat 201a arranged on the conveyor belt 102, and a receiving groove 201b is opened on the top of the positioning seat 201a, and a rivet brim groove 201c is opened on the inner wall of the receiving groove 201b, and the rivet brim groove 201c is matched with the brim of the rivet component 207, thereby improving the accuracy of the detection of the rivet component 207, and the positioning seat 201a is transported to the detection assembly 103 by the conveyor belt 102.

[0038] Furthermore, the feeding assembly 203 includes an output motor 203a arranged on the storage box 202, a rotating shaft 203b is installed at the output end of the output motor 203a, a custom wheel 203c is installed on the rotating shaft 203b, an outer wall of the custom wheel 203c is provided with a running groove 203d, a brim groove 203e is provided on the running groove 203d, a sliding groove 203f is provided inside the storage box 202, the sliding groove 203f is provided according to the rotation direction of the custom wheel 203c, and a matching groove 203g is provided on the sliding groove 203f, and two sets of vibration blocks 2 The gap between 04a is the brim of the rivet 207. The brim of the rivet 207 can be smoothly matched with the brim groove 203e of the custom wheel 203c by swinging the vibration block 204a. At this time, the custom wheel 203c can transport the rivet 207 through the operating groove 203d and the brim groove 203e to the sliding groove 203f and the matching groove 203g. The matching groove 203g matches the position of the brim groove 203e to support the rivet brim. The rivet 207 is finally stacked and discharged on the inclined surface at the end of the sliding groove 203f.

[0039] Furthermore, the vibration assembly 204 includes a vibration block 204a arranged in the storage box 202, a connecting rod 204b is installed on the outer wall of the vibration block 204a, a bending rod 204c is installed on the end of the connecting rod 204b, a rotating wheel 204d is installed on the outer wall of the rotating shaft 203b, and a wave groove 204e is arranged on the rotating wheel 204d, and the bending rod 204c is embedded in the wave groove 204e. When the rotating shaft 203b rotates, the wave groove 204e on the rotating wheel 204d drives the bending rod 204c embedded therein to swing, and the swing of the bending rod 204c drives the vibration block 204a on the connecting rod 204b to swing, and the gap between the two groups of vibration blocks 204a is the brim of the rivet part 207. The brim of the rivet part 207 can be smoothly matched with the brim groove 203e of the custom wheel 203c through the swing of the vibration block 204a.

[0040] Furthermore, the blanking assembly 205 includes a blanking port 205a arranged on the sliding groove 203f, and the rivet parts 207 of the sliding groove 203f place a group of rivet parts 207 on the support block 205e of the blanking port 205a through the partition assembly 206, and two groups of cavities 205b are arranged on one side of the blanking port 205a. A fixed spring 205c is installed on the inner wall of the cavity 205b, and a touch-pressure part 205d is installed at one end of the fixed spring 205c. A support block 205e is arranged on the touch-pressure part 205d, and the support block 205e is located in the blanking port 205a to support the rivet parts 207 on the blanking port 205a, and its two groups of cavities 205b are staggered on both sides of the blanking port 205a, so that the staggered spring rod 205d-5 can be synchronously rebounded into the cavity 205b.

[0041] Furthermore, the pressure piece 205d includes a pressure block 205d-1 arranged in the cavity 205b, the outer wall of the pressure block 205d-1 is provided with an inclined groove 205d-2, the inner wall of the cavity 205b is installed with a horizontal plate 205d-3, the top of the horizontal plate 205d-3 is installed with a pressure plate 205d-4, and the top of the positioning seat 201a is installed with two groups of staggered spring rods 205d-5. When the positioning seat 201a moves to below the blanking port 205a, the spring rod 205d-5 contacts the horizontal plate 205d-3 and the pressure plate 205d-4, and the pressure plate 205d-4 drives the support block 205e to move, thereby causing the rivet piece 207 of the blanking port 205a to fall into the positioning seat 201a.

[0042] The rest of the structure is the same as that of Example 1.

[0043] Operation process: The rivet pieces 207 are placed in the same direction inside the storage box 202, and the output motor 203a rotates cyclically to drive the customized wheel 203c on the rotating shaft 203b to rotate. The running groove 203d on the customized wheel 203c is customized according to the rivet piece 207, so that when the brim of the rivet piece 207 falls into the brim groove 203e, the rest of the rivet piece 207 can fit and contact with the inner wall of the running groove 203d, and when the rotating shaft 203b rotates, the wave groove 204e on the rotating wheel 204d drives the rivet piece 207 to be embedded therein. The bending rod 204c swings, and the swing of the bending rod 204c drives the vibration block 204a on the connecting rod 204b to swing. The gap between the two sets of vibration blocks 204a is the brim of the rivet part 207. The brim of the rivet part 207 can be smoothly matched with the brim groove 203e of the custom wheel 203c through the swing of the vibration block 204a. At this time, the custom wheel 203c can transport the rivet part 207 through the running groove 203d and the brim groove 203e to the sliding groove 203f and the matching groove 203g. The matching groove 203g matches the position of the brim groove 203e to support the brim of the rivet 207. The rivet 207 is finally stacked and discharged on the inclined surface at the end of the sliding groove 203f. At this time, the positioning seat 201a is moved by the conveyor belt 102. When the spring rod 205d-5 on the top of the positioning seat 201a moves to the bottom of the corresponding cavity 205b, the spring rod 205d-5 contacts the horizontal plate 205d-3 and the pressure plate 205d-4. The pressure plate 205d-4 drives the pressure block 205d-1 to move. The movement of the pressure block 205d-1 drives the support block 205e to move, so that a rivet piece 207 on the top side of the support block 205e is unsupported. At this time, the rivet piece 207 falls vertically into the receiving groove 201b of the positioning seat 201a and the rivet brim groove 201c. At this time, the rivet piece 207 completes the positioning and discharge, so that the rivet pieces 207 located under the detection component 103 are placed in the same direction and have the same position at the brim, which greatly improves the accuracy of the industrial camera's information entry of the rivet piece 207, thereby improving the accuracy of the sorting of the rivet piece 207.

[0044] Example 3

[0045] Reference Figure 6, which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that: the partition component 206 includes a shielding member 206a arranged in the cavity 205b, a limiting member 206b is installed on one side of the shielding member 206a, and a holding member 206c is installed inside the limiting member 206b. When the blanking port 205a is blanked, the shielding member 206a protrudes in the sliding groove 203f. At this time, the rivet member 207 slides to the shielding member 206a. When the blanking is completed and the supporting block 205e is restored, the limiting member 206b protrudes and the shielding member 206a no longer protrudes. At this time, a group of rivet members 207 between the limiting member 206b and the shielding member 206a can fall into the blanking port 205a.

[0046] Specifically, the shielding member 206a includes a slider 206a-1 arranged on the cavity 205b, a lower inclined block 206a-2 is installed on the top of the slider 206a-1, an upper inclined block 206a-3 is installed on the top of the lower inclined block 206a-2, and a first protrusion 206a-4 is installed on the upper inclined block 206a-3, and the support block 205e moves to drive the lower inclined block 206a-2 to lift the upper inclined block 206a-3, so that the first protrusion 206a-4 of the upper inclined block 206a-3 protrudes in the sliding groove 203f.

[0047] Furthermore, the limiting member 206b includes a second protrusion 206b-1 arranged in the storage box 202, a connecting block 206b-3 arranged on the second protrusion 206b-1, the end of the connecting block 206b-3 is movably connected to the bending block 206b-2 through a pin shaft, the bending point of the bending block 206b-2 is connected to the inside of the storage box 202 through a fixed axis, and the outer wall of the upper inclined block 206a-3 is installed with a push rod 206b-4, and the push rod 206b-4 extends to the bottom side of the bending block 206b-2.

[0048] Furthermore, the holding member 206c includes a fixed plate 206c-1 arranged in the storage box 202, and a compression spring 206c-2 arranged on the fixed plate 206c-1 and connected to the bending block 206b-2. The compression spring 206c-2 applies a downward elastic force to one end of the bending block 206b-2 for restoring the bending block 206b-2.

[0049] The rest of the structure is the same as that of Example 2.

[0050] Operation process: When the spring rod 205d-5 at the top of the positioning seat 201a moves to the bottom of the corresponding cavity 205b, the support block 205e is pressed and moves in the cavity 205b. At this time, the lower inclined block 206a-2 on the top side of the support block 205e lifts the upper inclined block 206a-3, so that the first protrusion 206a-4 of the upper inclined block 206a-3 protrudes, and when the upper inclined block 206a-3 moves upward, its push rod 206b-4 drives the bending block 206b-2 to rotate, and the rotation of the bending block 206b-2 drives the movable connected connecting block 206b-3 and the second protrusion 206b-1 to rotate downward, so that the first protrusion 206a-4 of the upper inclined block 206a-3 protrudes. The second protrusion 206b-1 does not protrude in the sliding groove 203f. At this time, the rivet part 207 can slide downward as a whole one unit, so that the rivet part 207 moves to the first protrusion 206a-4 and stops moving. When the support block 205e is restored, its first protrusion 206a-4 no longer protrudes in the sliding groove 203f, and the second protrusion 206b-1 rotates and moves to protrude in the sliding groove 203f. At this time, a group of rivet parts 207 between the first protrusion 206a-4 and the second protrusion 206b-1 are triggered by the second protrusion 206b-1 to slide into the blanking port 205a, thereby completing the automatic replenishment of the rivet parts 207 one group at a time.
