[0002] A connecting piece is a common mechanical connecting device that can fix two or more parts together to enhance the mechanical strength and stability of the structure.

[0003] The main functions of the connecting piece include the following aspects: fixing parts, the connecting piece can fix different parts together to form an integral structure, improving the overall strength and stability of the structure. Dispensing load, the connecting piece can evenly disperse the load on the stressed part, reducing the local concentration of force, thereby improving the load-bearing capacity of the structure. Adjusting the structure, the connecting piece can make fine adjustments during the structure connection process to make the connection part more accurate and enhance the overall performance of the structure.

[0041] A driving mechanism and a detection component are respectively disposed on the operating table 1. The driving mechanism is connected to the disk 2, and the detection component is connected to the driving mechanism through a transmission structure. When the driving mechanism operates, the disk 2 and the detection component will rotate alternately;

[0042] When the disc 2 rotates, it will drive the connecting piece in the detection groove 201 to move to the detection component and then stop. During this process, the detection component will remain stationary and detect the scratch on one side of the connecting piece; when the detection component rotates, it will move to the other side of the connecting piece for detection, and during this process, the disc 2 remains stationary.

[0044] As a further solution of the present utility model, the driving mechanism includes a driving disc 3, a first driven disc 4 and a second driven disc 5.

[0050] In this embodiment, since the center of the driving disk 3 is connected to the output end of the motor 10, when the motor 10 is started, the driving disk 3 will rotate along with the output end of the motor 10.

[0051] As a further solution of the present utility model, the detection component includes a bracket 11 arranged on the operation table 1 and a third rotating shaft 12 rotatably arranged on the bracket 11;

[0052] An L-shaped rod 13 is arranged on the outer wall of the third rotating shaft 12, a visual detector 14 is fixedly installed on the L-shaped rod 13, and the visual detector 14 corresponds to the position of the detection groove 201.

[0053] In this embodiment, since the visual detector 14 is rotatably arranged on the bracket 11 through the L-shaped rod 13 and the third rotating shaft 12, and the visual detector 14 corresponds to the position of the detection groove 201, when the third rotating shaft 12 rotates 180 degrees, the visual detector 14 will rotate from directly above the detection groove 201 to directly below the detection groove 201, so as to realize the detection of the front and back sides of the connecting piece in the detection groove 201.

[0054] As a further solution of the present utility model, the transmission structure includes a U-shaped frame 15 arranged on the operation table 1 and a rotating rod 16 rotatably arranged on the U-shaped frame 15. One end of the rotating rod 16 is provided with a second bevel gear 17, and the second bevel gear 17 meshes with the first bevel gear 8;

[0056] In this embodiment, since the second bevel gear 17 meshes with the first bevel gear 8, when the first bevel gear 8 rotates, the driving pulley 18 will rotate synchronously with the first bevel gear 8 through the rotating rod 16;

[0057] When the driving pulley 18 rotates, the driven pulley 19 will rotate with the driving pulley 18 through the belt 20, thereby driving the third rotating shaft 12 to rotate, and the third rotating shaft 12 will drive the visual detector 14 to rotate synchronously through the L-shaped rod 13;

[0058] In addition, the diameter of the driving pulley 18 is set to be twice that of the driven pulley 19. Therefore, when the driving pulley 18 rotates 90 degrees, the driven pulley 19 will rotate 180 degrees.

[0060] In this embodiment, a plurality of connecting pieces are stacked inside the storage sleeve 22. Since the bottom end of the storage sleeve 22 is in contact with the top surface of the disc 2, the connecting pieces inside the storage sleeve 22 will not fall out. When the disc 2 starts to rotate and the detection groove 201 rotates to the lower part of the storage sleeve 22, the connecting pieces inside the storage sleeve 22 will fall into the detection groove 201 under the action of gravity, thereby realizing the automatic blanking of the connecting pieces.

[0061] As a further solution of the present utility model, a pushing assembly is further disposed on the operation table 1. The pushing assembly includes a fixing frame 23 disposed on the top surface of the operation table 1 and an electric push rod 24 horizontally and fixedly installed on the fixing frame 23;

[0064] In this embodiment, when the connecting piece detected by the vision detector 14 in the detection groove 201 moves to the position of the electric push rod 24, the output end of the electric push rod 24 will pass through the through hole 203 to push out the connecting piece in the detection groove 201, so that the empty detection groove 201 can move to the storage sleeve 22 to continue receiving materials.

[0065] As a further solution of the present utility model, the disc 2 is made of a transparent material. The depth of the detection groove 201 is the same as the thickness of a single connecting piece, and the diameter of the through hole 203 is larger than the diameter of the output end of the electric push rod 24.

[0066] In this embodiment, the transparent disc 2 facilitates the vision detector 14 to detect the reverse side of the connecting piece through the disc 2; since the depth of the detection groove 201 is the same as the thickness of a single connecting piece, only one connecting piece in the storage sleeve 22 can fall into the detection groove 201 at a time; the diameter of the through hole 203 is larger than the diameter of the output end of the electric push rod 24, so that the output end of the electric push rod 24 can penetrate through the through hole 203 and enter the detection groove 201 to push out the connecting piece.
