Description

Technical Field

[0001] This utility model relates to the field of parts sorting technology, specifically to a parts sorting device with error prevention function. Background Technology

[0002] In the automotive manufacturing industry, tubular parts are important functional components, and their quality directly affects the safety and reliability of vehicles. These parts typically require sorting during the production process to ensure they meet requirements for dimensions, shape, and surface quality.

This sorting device includes a mounting platform, a rotating device tilted and mounted on the mounting platform, the rotating device having a receiving groove for placing tubular parts, and the rotating device being able to rotate about its axis to receive tubular parts that fall into the rotating receiving groove by gravity. It also includes a conveying device for conveying tubular parts in a single row along the conveying direction. The conveying device is tilted and mounted on the mounting platform. A sorting trough plate is rotatably set at the end of the conveying device away from the rotating device, and this sorting trough plate has sorting slots for receiving the tubular parts conveyed by the conveying device.

[0032] The inner surface of the gripper 313 is arc-shaped and used to clamp and fix the tubular automotive parts 4. A silicone layer is fixedly connected to the arc-shaped surface.

[0033] The rotational correction assembly includes a rotating block 315, a fixed plate 316, and a motor 317. The housing of the pneumatic finger 314 is fixedly connected to the rotating block 315. The rotating block 315 is rotatably connected to the fixed plate 316. The housing of the motor 317 is fixedly connected to the fixed plate 316.

[0034] The clamping and pushing assembly includes a fixed rod 318, a clamping and fixing block 319, and a clamping cylinder 320.

[0036] The stepping workpiece feeding mechanism 2 includes a feeding fixing component, a feeding moving component, a feeding driving component, and a feeding component. The feeding fixing component is connected to the base plate 1, the feeding moving component is connected to the feeding driving component, and the feeding component is connected to the base plate 1.

[0037] The feeding and fixing assembly includes a fixing plate 211, a feeding fixing block 212, and a limiting block 213. The fixing plate 211 is fixedly connected to the inner wall of the base plate 1, multiple sets of feeding fixing blocks 212 are fixedly connected to the upper end of the fixing plate 211, and the limiting block 213 is fixedly connected to the front end of the fixing plate 211.

[0038] The upper end of the feeding fixing block 212 is inclined, which is used to roll down along the inclined surface when the tubular automotive parts 4 are lifted, so as to achieve step feeding.

[0039] The feeding moving assembly includes a moving plate 214 and moving blocks 215. Multiple sets of moving blocks 215 are fixedly connected to the upper end of the moving plate 214. The moving blocks 215 are symmetrically distributed about the front and back of the moving plate 214. The moving blocks 215 are located on the front and back sides of the feeding fixed block 212. The lower end of the moving plate 214 is connected to the feeding drive assembly.

[0040] The upper end of the moving block 215 is an inclined surface. The number of sets of the feeding fixed block 212, the moving block 215 and the error-proof workpiece correction mechanism 3 are the same and correspond one-to-one. The number of sets of the three determines the number of automotive tubular parts 4 fed each time, which can be adjusted according to actual production needs.

[0041] The feeding drive assembly includes a push plate 216, a feeding cylinder 217, and a cylinder connecting plate 218. The lower end of the moving plate 214 is fixedly connected to the push plate 216. The output end of the feeding cylinder 217 is fixedly connected to the push plate 216. The outer shell of the feeding cylinder 217 is fixedly connected to the cylinder connecting plate 218. Both ends of the cylinder connecting plate 218 are fixedly connected to the inner walls of the two sets of base plates 1.

[0042] The feeding assembly includes an upper inclined block 219 and a lower inclined block 220. The upper inclined block 219 and the lower inclined block 220 are respectively fixedly connected to the substrate 1. The left end of the lower inclined block 220 is in contact with the right end of the feeding fixing block 212 and is at the same height. The inclined groove formed between the upper inclined block 219 and the lower inclined block 220 allows the automotive tubular component 4 to roll downwards.

[0043] In this invention, the tubular automotive component 4 rolls along the upper inclined block 219 and the lower inclined block 220 until it is blocked by the loading fixing block 212. Then, the loading cylinder 217 on the cylinder connecting plate 218 is activated, pushing the push plate 216 upwards. This causes the moving plate 214 and the moving block 215 to move upwards. At this time, the tubular automotive component 4 is pushed upwards by the moving block 215 until the right end of the loading fixing block 212 and the left end of the moving block 215 are at the same height. Then, the tubular automotive component 4 rolls forward along the inclined plane to the left until it is blocked by the loading fixing block 212. The left-side moving block 215 blocks the movement. During this period, because the moving block 215 moves upward, the right end of the moving block 215 always blocks the new automotive tubular component 4 from moving forward. The feeding cylinder 217 is activated to pull down the push plate 216, and the moving block 215 moves downward. As a result, the initial automotive tubular component 4 and the new automotive tubular component 4 roll forward. The two sets of automotive tubular components 4 are blocked by the left-side moving block 215 respectively. The above operation is repeated until the leftmost automotive tubular component 4 moves to the right end of the limiting block 213 and is blocked by the limiting block 213.

[0044] The camera 312 on the connecting arm 311 performs sequential detection to ensure that the protrusion 41 of the tubular automotive component 4 is positioned at the rear end. If misalignment of the tubular automotive component 4 is detected, the clamping cylinder 320 is activated, pushing the clamping fixing block 319 and fixing rod 318 upward. This causes the rotating block 315, fixing plate 316, pneumatic fingers 314, and gripper 313 to move upward until the gripper 313 is at the same height as the tubular automotive component 4. The pneumatic fingers 314 are then activated, causing the gripper 313 to clamp the tubular automotive component 4 inward. At this point, the correction cylinder 322 on the correction fixing block 323 is activated, pushing the connecting plate 321 upward. This causes the clamping cylinder 320, clamping fixing block 319, fixing rod 318, motor 317, fixing plate 316, and rotating block 315 to move upward. The rotating block 315, pneumatic finger 314, gripper 313, and the automotive tubular component 4 held by gripper 313 move upward until the automotive tubular component 4 moves above the base plate 1. The motor 317 is started, causing the rotating block 315 to rotate 180°, thereby rotating the automotive tubular component 4 180°. The protrusion 41 is located at the rear end, and the position correction of the automotive tubular component 4 is completed. At this time, the correction cylinder 322 is started to reset. After the correction cylinder 322 is reset, the pneumatic finger 314 is started to reset, thereby resetting the gripper 313. At this time, the gripper 313 no longer holds the automotive tubular component 4. The clamping cylinder 320 is started to reset, causing the gripper 313 to move downward and reset. The above operation is repeated to detect and correct misalignment of multiple sets of automotive tubular components 4 on the loading fixing block 212.

[0045] After all the sets of automotive tubular parts 4 on the loading fixing block 212 have been inspected and corrected, a robot or robotic arm is used to transport the automotive tubular parts 4 to the next workstation. The above steps are repeated to achieve error-proof sorting and correction of all automotive tubular parts 4.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
