[0040] The following detailed description is illustrative and non-limiting. It is intended to provide a basic understanding of the present application and is not intended to identify the key or decisive elements of the present application or to limit the scope of protection. As long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any manner.

[0041] When a component is referred to as being “disposed on” another component, it can be directly disposed on the other component or there may be a component intervening therebetween. When a component is referred to as being “connected to” another component, it can be directly connected to the other component or there may be a component intervening therebetween.

[0042] It can be understood that the term "perpendicular" is used to describe the ideal state between two components. In actual production or use, there may be a state between the two components that is approximately perpendicular or equal. For example, combined with numerical descriptions, perpendicular can refer to the angle between two straight lines being in the range of 90°±10°, perpendicular can also refer to the dihedral angle between two planes being in the range of 90°±10°, and perpendicular can also refer to the angle between a straight line and a plane being in the range of 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0043] In the description, claims and drawings of this application, the terms first, second and the like (if any) are used to distinguish between similar objects rather than to describe a particular sequential order.

[0044] An embodiment of the present application provides a detection and classification device, comprising a detection member, a conveying mechanism, a positioning mechanism and a rotating mechanism. The detection member is used to detect a workpiece. The conveying mechanism passes through the detection member along a first direction, and is used to drive the workpiece to move, and the first direction is the conveying direction of the conveying mechanism. The positioning mechanism is provided on one side of the conveying mechanism, and is used to locate the position of the workpiece along a first direction and a second direction according to the detection result of the detection member, and the first direction is perpendicular to the second direction. The rotating mechanism is provided above the conveying mechanism, and when the workpiece detected by the detection member does not meet the requirements, the positioning mechanism locates the position of the workpiece that does not meet the requirements, and the rotating mechanism is used to adsorb the workpiece, rotate the workpiece, and adjust the position of the workpiece to distinguish the workpiece that does not meet the requirements. The workpiece is driven to move by the conveying mechanism so that the workpiece passes through the detection member for detection. When the workpiece detected by the detection member does not meet the requirements, the positioning mechanism and the rotating mechanism cooperate to adjust the position of the workpiece, and then distinguish the workpiece that does not meet the requirements, thereby realizing automatic detection and classification, improving efficiency, and reducing the occurrence of missed detection.

[0045] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features of the embodiments may be combined with each other.

[0046] See also Figure 1 An embodiment of the present application provides a detection and classification device 100 , including a detection member (not shown) for detecting a workpiece 200 .

[0047] In some embodiments, the workpiece 200 includes screw holes, and the inspection member is used to inspect whether the screw holes meet the requirements.

[0048] In some embodiments, the detection and classification device 100 includes a conveying mechanism 10 , which passes through the detection member along a first direction X to move the workpiece 200 , wherein the first direction X is a conveying direction of the conveying mechanism 10 .

[0049] In some embodiments, the inspection and classification device 100 includes a positioning mechanism 20, which is arranged on one side of the conveying mechanism 10 and is used to locate the position of the workpiece 200 along the first direction X and the second direction Y according to the inspection results of the inspection piece, where the first direction X is perpendicular to the second direction Y.

[0050] In some embodiments, the inspection and classification device 100 includes a rotating mechanism 30, which is disposed above the conveying mechanism 10. When the workpiece 200 inspected by the inspection member does not meet the requirements, the positioning mechanism 20 locates the position of the workpiece 200, and the rotating mechanism 30 is used to absorb the workpiece 200, rotate the workpiece 200, and adjust the position of the workpiece 200 to distinguish the workpiece 200 that does not meet the requirements.

[0051] In this application, the conveying mechanism 10 drives the workpiece 200 to move, so that the workpiece 200 passes through the inspection unit. If the workpiece 200 does not meet the requirements of the inspection unit, the positioning mechanism 20 and the rotating mechanism 30 cooperate to adjust the position of the workpiece 200, thereby distinguishing the workpiece 200 that does not meet the requirements, realizing automatic inspection and classification, improving efficiency, and reducing the occurrence of missed inspections.

[0052] In some embodiments, the inspection and classification device 100 includes a first robot for placing uninspected workpieces on the conveying mechanism 10 in sequence.

[0053] In some embodiments, the inspection and classification device 100 includes an air blowing mechanism.

[0054] In some embodiments, the detection and classification device 100 includes a base 40 , a conveying mechanism 10 connected to the base 40 , and a rotating mechanism 30 connected to the base 40 .

[0055] See also Figure 1 and Figure 2 In some embodiments, the conveying mechanism 10 includes a first end 10a and a second end 10b along a first direction X. The first end 10a extends from the detection member, and the second end 10b extends from the detection member. The workpiece 200 is placed on the conveying mechanism 10 from the first end 10a and moves toward the second end 10b.

[0056] In some embodiments, the conveying mechanism 10 includes a conveying frame 11 , which is fixedly connected to the base 40 .

[0057] In some embodiments, the conveying mechanism 10 includes a conveyor belt 12 and a support member 13. The conveyor belt 12 is drivingly connected to the conveyor frame 11. The support member 13 is located between the endless conveyor belts 12 and is used to support the workpiece 200 during positioning.

[0058] In some embodiments, the conveyor mechanism 10 includes a conveyor drive 14 and a rotating shaft 15. The conveyor belt 12 is connected to the rotating shaft 15, and the conveyor drive 14 is connected to the rotating shaft 15. The conveyor drive 14 drives the rotating shaft 15 to rotate, thereby driving the conveyor belt 12 to rotate, so that the conveyor belt 12 moves the workpiece 200. Optionally, the conveyor drive 14 is connected to the rotating shaft 15 via a synchronous belt.

[0059] See also Figures 2 to 5In some embodiments, the positioning mechanism 20 includes a first positioning member 20a, and the first positioning member 20a includes a first driving member 21, a first positioning portion 22, and a first connecting member 23. The first driving member 21 and the first positioning portion 22 are arranged in the second direction Y. The first connecting member 23 connects the first driving member 21 and the first positioning portion 22. The first driving member 21 drives the first connecting member 23, and the first connecting member 23 drives the first positioning portion 22 to move. The first positioning portion 22 pushes the workpiece 200, and the first positioning portion 22 causes the workpiece 200 to abut against the conveying rack 11, thereby positioning the workpiece 200 along the second direction Y.

[0060] In some embodiments, the conveying rack 11 includes an opening 111 that penetrates the conveying rack 11 along the second direction Y. At least a portion of the first positioning portion 22 is disposed in the opening 111 to position the workpiece 200 in the conveying rack 11 through the opening 111 .

[0061] In some embodiments, the first positioning portion 22 includes a first crossbar 221 and a positioning roller 222. The first crossbar 221 is fixedly connected to the first connector 23. The positioning roller 222 is connected to the first crossbar 221. When positioning the workpiece 200, the positioning roller 222 contacts and connects with the workpiece 200, reducing the contact area with the workpiece 200 and the risk of crushing the workpiece 200 during positioning. The rolling positioning roller 222 also facilitates the movement of the workpiece 200 on the conveyor belt 12, preventing the workpiece 200 from getting stuck during movement, and facilitating continuous production.

[0062] In some embodiments, the positioning rollers 222 are disposed at both ends of the first crossbar 221 along the first direction X. Increasing the distance between the positioning rollers 222 at both ends further facilitates positioning the workpiece 200 and prevents the workpiece 200 from getting stuck during movement.

[0063] In some embodiments, the circumference of the positioning roller 222 is coated with a flexible material to further reduce the risk of crushing the workpiece 200 during positioning.

[0064] In some embodiments, the first connecting member 23 includes a base plate 231, a connecting plate 232, and a connecting rod 233. The base plate 231 is fixedly connected to the conveyor rack 11. The connecting plate 232 is slidably connected to the base plate 231 and is connected to the first cross bar 221. The connecting rod 233 connects the first driving member 21 and the connecting plate 232. The first driving member 21 drives the connecting rod 233, which causes the connecting plate 232 to slide on the base plate 231 and pushes the first cross bar 221 to move, so that the positioning roller 222 abuts the workpiece 200 against the conveyor rack 11.

[0065] In some embodiments, the first connecting member 23 includes an elastic member 234, which is connected to the connecting rod 233. When the first positioning portion 22 contacts the workpiece 200, the elastic member 234 is in a compressed state, thereby achieving a buffering effect and allowing the positioning roller 222 to maintain the force acting on the workpiece when positioning the workpiece 200.

[0066] In some embodiments, the base plate 231 is provided with a slide rail 2311 and a slider 2312 , and the slider 2312 is connected to the slide rail 2311 . The connecting plate 232 is fixedly connected to the slider 2312 .

[0067] In some embodiments, the first connector 23 includes a connecting post 235 and a connecting buckle 236. The connecting post 235 is fixed to the connecting plate 232. The first crossbar 221 is connected to the connecting post 235. The connecting post 235 has a recessed portion (not shown) circumferentially therearound. The connecting buckle 236 is located within the recessed portion and on the side of the first crossbar 221 facing away from the base plate 231, facilitating assembly and disassembly of the first crossbar 221 and the connecting post 235.

[0068] In some embodiments, the first connecting member 23 includes a connecting block 237. The connecting plate 232 has a first mounting slot 2321, and the connecting block 237 is fixed to the first mounting slot 2321. The connecting block 237 has a second mounting slot 2371. One end of the connecting rod 233 is clamped in the second mounting slot 2371, and the other end is connected to the first driving member 21.

[0069] In some embodiments, the first connecting member 23 includes a protective plate 238, which is provided to cover the first driving member 21 and the first connecting member 23 to reduce the entry of foreign matter and dust, thereby ensuring positioning accuracy.

[0070] In some embodiments, the positioning mechanism 20 includes a second positioning member 20 b, which includes a second driving member 24 and a second positioning portion 25. The second driving member 24 is fixed to the base 40 and connected to the second positioning portion 25. The second driving member 24 drives the second positioning portion 25 to extend along the third direction Z, restricting the movement of the workpiece 200 to position the workpiece 200 along the first direction X. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0071] In some embodiments, the positioning mechanism 20 includes another second positioning member 20 b for blocking the next workpiece 200 .

[0072] See also Figure 5 In some embodiments, the rotating mechanism 30 includes a bracket 31 , which is fixed to the base 40 or the conveying rack 11 .

[0073] In some embodiments, the rotating mechanism 30 includes a third driving member 32 , and the third driving member 32 is fixedly connected to the bracket 31 .

[0074] In some embodiments, the rotating mechanism 30 includes a rotating member 33 and a suction member 34. The rotating member 33 is connected to the third driving member 32, and the suction member 34 is connected to the rotating member 33. The third driving member 32 drives the rotating member 33 and the suction member 34 to move toward the workpiece 200 along the third direction Z. The suction member 34 suctions the workpiece 200 that does not meet the requirements. The third driving member 32 lifts the workpiece 200 that does not meet the requirements and drives the workpiece 200 to rotate via the rotating member 33 to adjust the position of the workpiece 200.

[0075] In some embodiments, the rotating member 33 drives the workpiece 200 to rotate 180° to facilitate partitioning of the workpieces 200 that do not meet the requirements.

[0076] In some embodiments, when the third driving member 32 lifts the workpiece 200 that does not meet the requirements, the first positioning member 20 a releases the positioning of the workpiece 200 .

[0077] In some embodiments, the detection and classification device 100 includes a sensor, which is arranged along the first direction X on the path conveyed to the support member 13. When the detection member detects a workpiece 200 that does not meet the requirements, the detection member sends a signal to the positioning mechanism 20 and the rotation mechanism 30. When the sensor detects the workpiece 200 that does not meet the requirements, the second positioning portion 25 extends along the third direction Z, and the first positioning portion 22 pushes the workpiece 200. The first positioning portion 22 abuts the workpiece 200 against the conveyor rack 11, and then rotates and changes position through the rotation mechanism 30, placing the workpiece 200 in the changed position on the conveyor belt 12 to continue moving along the first direction X.

[0078] In some embodiments, the inspection and classification device 100 includes a second robot, and the second end 10b is provided with a second positioning member 20b for limiting the position of the inspected workpiece 200. The second robot is arranged on one side of the second end 10b for moving the workpiece 200 that meets the requirements to the next workstation or the next assembly line, and moving the workpiece 200 that does not meet the requirements to the material receiving area.

[0079] When the inspection and sorting device 100 is in use, workpieces 200 are first placed sequentially on the conveyor belt 12. The conveyor belt 12 then drives the workpieces 200 through the inspection element. When a workpiece passes inspection, it follows the conveyor belt 12 to the second end 10b. If a workpiece that does not meet the requirements is detected, the inspection element sends a signal to the positioning mechanism 20 and the rotation mechanism 30. The second positioning portion 25 extends in the third direction Z, and the first positioning portion 22 pushes the workpiece 200. The first positioning portion 22 then abuts the workpiece 200 against the conveyor frame 11. The rotation mechanism 30 then rotates and repositions the workpiece 200, placing it on the conveyor belt 12 and continuing to move it in the first direction X to the second end 10b. A second robot classifies and moves workpieces 200 that pass and fail inspection.

[0080] In this application, the conveying mechanism 10 drives the workpiece 200 to move, so that the workpiece 200 passes through the inspection unit. If the workpiece 200 does not meet the requirements of the inspection unit, the positioning mechanism 20 and the rotating mechanism 30 cooperate to adjust the position of the workpiece 200, thereby distinguishing the workpiece 200 that does not meet the requirements, realizing automatic inspection and classification, improving efficiency, and reducing the occurrence of missed inspections.
