DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a workpiece inspection and feeding structure comprises a base 1 and a conveyor belt 3. The conveyor belt 3 is arranged in front of the base 1, and a plurality of workpiece bodies 4 are arranged on the top of the conveyor belt 3. A detection table 2 is arranged at the front position of the top of the base 1, and a driving cylinder 5 is installed at the rear position of the top of the base 1 through a mounting plate;

[0022] A driving push rod 7 is installed at the front section of the driving cylinder 5, and the front section of the mounting plate is fixedly connected with sliding rods 6 on both sides. A feeding assembly 8 is provided on the outer ring of the sliding rod 6. The feeding assembly 8 includes a mounting frame 9, and the mounting frame 9 is slidably installed on the outer ring of the sliding rod 6, and the end of the driving push rod 7 away from the driving cylinder 5 is connected to the top of the mounting frame 9, and the lower end of the mounting frame 9 is fixedly connected with an adjusting rod 10 on both sides, and the outer ring of the adjusting rod 10 is slidably installed with a movable plate 11 at the front and rear end positions, and the tops of the two movable plates 11 are fixedly installed with an electric telescopic rod 12, and the lower ends of the push rods of the two electric telescopic rods 12 are installed with a three-jaw chuck 13, and the specifications of the three-jaw chuck 13 match the workpiece body 4.

[0023] In this embodiment, a plurality of limit plates matching the workpiece body 4 are arranged on the top of the conveyor belt 3, the bottom outer ring of the workpiece body 4 fits with the inner wall of the limit plate, and the limit plates are arranged equidistantly on the conveyor belt 3, which is convenient for conveying the workpiece body 4. At the same time, the position of the workpiece body 4 can be limited by the set limit plates to prevent it from sliding and causing clamping failure.

[0024] In this embodiment, a distance sensor 14 is installed at one end of the two sliding rods 6 away from the driving cylinder 5, and a distance sensor 2 15 is installed at an upper position on one side of the mounting plate, and the distance sensor 14 and the distance sensor 2 15 are matched with the mounting frame 9. By setting the distance sensor 14 and the distance sensor 2 15, it is convenient to detect the position of the mounting frame 9 and perform material discharging and loading at the same time.

[0025] In this embodiment, the base 1 is set in a "Π" shape, and a drop-out port matching the workpiece body 4 is opened at the top rear position of the base 1. By placing the external collection frame into the interior of the base 1, the unqualified workpiece body 4 is discharged from the drop-out port, and the qualified and unqualified workpiece bodies 4 are classified and discharged to avoid mixing with each other.

[0026] In this embodiment, the bottom surface of the three-jaw chuck 13 does not contact the top surface of the detection table 2 and the limit plate, and the top surface of the three-jaw chuck 13 does not contact the adjusting rod 10, and they do not contact each other, which can prevent the three-jaw chuck 13 and the limit plate from interfering with the three-jaw chuck 13 in clamping and loading the workpiece body 4.

[0027] In this embodiment, the outer ring of the adjusting rod 10 is provided with an external thread, and the adjusting rod 10 is threadedly connected with a plurality of adjusting nuts that match the movable plate 11 through the external thread. By screwing the adjusting nuts in turn, the fixed position of the movable plate 11 on the adjusting rod 10 is adjusted, so that the movable plate 11 can be adjusted according to the position of the detection platform 2 and the workpiece body 4.

[0028] It should be noted that the utility model is a workpiece inspection and feeding structure. When in use, first, because the three-jaw chuck 13 is fixed to the movable plate 11 through various components, and the adjusting rod 10 is provided with an adjusting nut that matches the movable plate 11, the adjusting nut can be screwed in turn according to the position of the limit plate and the inspection table 2 to adjust the fixed position of the movable plate 11 on the adjusting rod 10, thereby driving the three-jaw chuck 13 to move, and the two three-jaw chucks 13 can be adjusted to a suitable position as needed to clamp the workpiece body 4;

[0029] When the workpiece body 4 is conveyed by the conveyor belt 3 to the bottom of one of the three-jaw chucks 13, the electric telescopic rod 12 matched therewith can be started as needed to extend the push rod of the electric telescopic rod 12, thereby driving the three-jaw chuck 13 to descend, and then the three-jaw chuck 13 is controlled to tighten for clamping, and after clamping, the push rod of the electric telescopic rod 12 can be controlled to retract, thereby clamping the workpiece body 4;

[0030] After the workpiece body 4 is clamped, the driving push rod 7 on the driving cylinder 5 can be controlled to retract, driving the three-jaw chuck 13 holding the workpiece body 4 to approach the detection table 2. At the same time, when the distance sensor 15 detects the mounting frame 9, the retraction of the driving push rod 7 is stopped, and then the push rod of the electric telescopic rod 12 is continued to be controlled to extend, and after extending to a suitable length, the three-jaw chuck 13 is controlled to relax, thereby releasing the fixation of the workpiece body 4, allowing it to fall onto the detection table 2 and be detected;

[0031] When the inspection is qualified, the electric telescopic rod 12 and the three-jaw chuck 13 can be controlled according to the above steps to clamp the workpiece body 4 that has passed the inspection, and then the driving push rod 7 can be extended to push the mounting frame 9 away from the inspection table 2, thereby driving the workpiece body 4 to move in the direction of the conveyor belt 3, and after the distance sensor 14 detects the mounting frame 9, the extension of the driving push rod 7 is stopped. At this time, the electric telescopic rod 12 is located at a suitable position above the conveyor belt 3, and then the push rod of the electric telescopic rod 12 can be extended, thereby driving the workpiece body 4 to fall toward the conveyor belt 3, and after the appropriate height, the lock of the three-jaw chuck 13 on the workpiece body 4 is released, and then the push rod of the electric telescopic rod 12 can be controlled to retract for reset, and after resetting, the conveyor belt 3 is controlled to transport the workpiece body 4 again, until another workpiece body 4 is located below the three-jaw chuck 13 again, and the above steps are repeated, thereby multiple workpiece bodies 4 are inspected;

[0032] When it is detected that the workpiece body 4 is unqualified, the three-jaw chuck 13 close to the driving cylinder 5 can be moved to the top of the unqualified workpiece body 4 by controlling the telescopic length of the driving push rod 7, and then the electric telescopic rod 12 and the three-jaw chuck 13 can be controlled in sequence according to the above steps to clamp the workpiece body 4. After clamping, the driving push rod 7 can be controlled to retract again until the distance sensor 15 detects the mounting frame 9. Since the workpiece body 4 is clamped by the three-jaw chuck 13 close to the driving cylinder 5, the workpiece body 4 is located at the blanking port set at the rear part of the base 1. Then, the lock of the workpiece body 4 is released, so that the workpiece body 4 falls into the inside of the base 1, and the external collection frame can be placed in the inside of the base 1 to collect the unqualified workpiece body 4.

[0033] After that, after the unqualified workpiece body 4 falls, and after ensuring that the electric telescopic rod 12 is reset, the driving push rod 7 can be controlled according to the above steps to push the mounting frame 9 in the direction away from the driving cylinder 5 until the mounting frame 9 is detected by the distance sensor 14 again, and then the conveyor belt 3 is controlled to convey the workpiece body 4 again until another workpiece body 4 is located under the three-jaw chuck 13 again. Therefore, by repeating the above steps, multiple workpiece bodies 4 can be inspected in turn, and qualified and unqualified workpiece bodies 4 can be classified and discharged to avoid mixing them with each other.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
