[0020] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0021] A nut thread detection device provided by the present invention includes a rotary thread detection mechanism 1, a nut blanking mechanism 2 and a nut collection box 3. The nut blanking mechanism 2 is fixedly installed on the rotary thread detection mechanism 1. Two nut collection boxes 3 are placed below the nut blanking mechanism 2, and the nut collection boxes 3 are located on one side of the rotary thread detection mechanism 1.

[0022] The rotary thread detection mechanism 1 includes a base 11, a rotary platform 12, a detection groove 13, a bracket 14, a cylinder 15 and a thread scanning detection head 16. The nut blanking mechanism 2 is fixedly installed on the base 11; the output end of the motor built in the base 11 is fixedly connected to the rotary platform 12. The rotary platform 12 is installed on the base 11 through a guide rail. The detection grooves 13 are evenly arranged on the rotary platform 12; the bracket 14 is fixedly installed on the base 11, and the output end of the cylinder 15 fixedly installed on the bracket 14 is fixed to the thread scanning detection head 16. The rotary thread detection mechanism 1 is used for cyclic detection of nuts.

[0023] The nut blanking mechanism 2 includes a tray 21, a notch 22, a falling channel 23, a servo motor 24, and a baffle 25. The tray 21 is fixedly installed on the base 11. A notch 22 is provided on the tray 21, and the falling channel 23 is fixedly installed thereon. The output end of the servo motor 24 fixedly installed on the falling channel 23 is fixed to the baffle 25. Two nut collection boxes 3 are placed below the falling channel 23. The nut blanking mechanism 2 is used to classify the nuts that have been inspected.

[0024] Embodiment 1:

[0025] Specifically, a plurality of detection slots 13 are formed through the rotary platform 12. The detection slots 13 are evenly distributed on the rotary platform 12, and a nut to be detected is pre-placed in each slot. As the rotary platform 12 rotates, these detection slots 13 sequentially pass under the position directly below the thread scanning detector 16, forming a dynamic detection station. Specifically, no matter how the rotary platform rotates, it is always ensured that there is a detection slot 13 exactly below the thread scanning detector 16, and this position is defined as the detection station. Such a design ensures the continuity and efficiency of detection.

[0026] Specifically, the cross-section of the tray 21 is designed in a "U" shape, which is convenient for cooperating with the rotary platform 12 and provides enough space to install the falling channel 23. On one side of the tray 21, a notch 22 is opened, and the inclined falling channel 23 is fixedly installed below this notch 22. These detection slots 13 sequentially pass above the notch 22. The starting end of the falling channel 23 is exactly aligned with the notch 22 to ensure that the nuts inspected from the rotary platform 12 can smoothly fall into it.

[0027] Specifically, the falling channel 23 adopts a unique "Y" - shaped structure design and is installed obliquely on the tray 21 as a whole. This design not only facilitates the smooth sliding of the nuts but also cleverly realizes the function of classified collection. The falling channel 23 is divided into two branch channels during the downward extension process, and a nut collection box 3 is placed below each branch channel. These two nut collection boxes 3 are respectively used to store the nuts that pass the inspection and the nuts that fail the inspection. Through such a design, the device can automatically guide the nuts with different inspection results to different collection boxes, realizing efficient classified collection.

[0028] Specifically, the baffle 25 is a key component in the falling channel 23, and it is located at the junction of the two branch channels. The baffle 25 rotates or moves driven by the servo motor 24, thereby controlling the flow direction of the nuts. When the thread scanning detection head 16 completes the detection of a nut and determines whether it is qualified or unqualified, the servo motor 24 will receive the corresponding signal and drive the baffle 25 to rotate to the corresponding position. If the nut is qualified, the baffle 25 will guide it into the left branch channel; if the nut is unqualified, it will be guided into the right branch channel. In this way, the real-time feedback and classified collection of the detection results are achieved.

[0029] Embodiment 2:

[0030] First, a nut to be detected is pre-placed in each detection slot 13 of the rotating platform 12. And the nut collection boxes 3 are respectively placed on one side of the device to receive the qualified and unqualified nuts. The motor built in the base 11 starts, driving the rotating platform 12 to rotate. As the rotating platform 12 rotates, the detection slots 13 sequentially pass through the position directly below the thread scanning detection head 16, that is, the detection station. When the detection slot 13 is at the detection station, the cylinder 15 drives the thread scanning detection head 16 to descend to perform thread scanning detection on the nut in the slot. After the detection is completed, the thread scanning detection head 16 rises and resets, and at the same time the system sends the detection result (qualified / unqualified) to the servo motor 24. The detected nut continues to rotate with the rotating platform 12 and reaches the position directly above the notch 22 on the tray 21. The nut falls from the detection slot 13 and enters the falling channel 23 through the notch 22. The "Y"-shaped structure design of the falling channel 23 enables the nut to smoothly slide to the junction of the two branch channels. According to the detection result, the servo motor 24 drives the baffle 25 to rotate to the corresponding position: if the nut is qualified, the baffle 25 guides the nut into the left branch channel and finally falls into the corresponding nut collection box 3. If the nut is unqualified, the baffle 25 guides the nut into the right branch channel and also falls into the corresponding nut collection box 3. The above process is continuously repeated, the rotating platform 12 continues to rotate, new nuts to be detected are sent to the detection station, and the detected nuts are classified and collected.

[0031] Using the technical solution of the present utility model, or those skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
