By setting the feeding assembly 3, the lifting assembly 5 and the testing assembly 4, the testing assembly 4 can be used to detect the pitch of the cylindrical product. The cylindrical product is automatically fed to the product lifting component 5 through the inclined feeding component 3, and the lifting component 5 lifts the product to the secondary detection mechanism (the second top block 11 and the supporting block 12 are used as the secondary detection components). The lifting component 5 rises to lift the product to the detection position, and the inspection component 4 scans the surface of the product. The detection software detects and analyzes the pitch. After the detection is completed, the mechanism descends and the product rolls to the rear installation plate 9. The product lifting component 5 of the utility model can adjust the hanging platform distance according to the diameter of the product, and can realize the use of multiple sizes.
[0023] The feeding assembly 3 includes a pad block 301, which is fixedly mounted on one side of the upper surface of the carrying plate 2, and a sliding plate 302 is fixedly mounted on the top of the pad block 301. The pad block 301 is provided to support and position the sliding plate 302, so that the sliding plate 302 remains in an inclined state, which facilitates the cylindrical product to roll to its bottom end.
[0024] A plurality of groups of notches 7 are provided on one side of the slide plate 302. The groups of notches 7 are arranged at equal distances, and the slide plate 302 is arranged at an angle. By providing the notches 7, the block 502 can easily lift the cylindrical product.
[0025] The lifting assembly 5 includes a first top block 501, and a plurality of groups of clamping blocks 502 adapted to the notches 7 are fixedly connected to the top of the first top block 501, and the plurality of groups of clamping blocks 502 are equidistantly arranged, and the plurality of groups of clamping blocks 502 are slidably connected to the inside of the plurality of groups of notches 7, respectively. The power device inside the chassis 1 provides a lifting force for the first top block 501;

A plurality of groups of second notches 10 are provided on one side of the mounting plate 9. When the cylindrical product is detected by the pitch, the first top block 501 is lowered, thereby driving a plurality of groups of clamping blocks 502 to be lowered. When the cylindrical product contacts the mounting plate 9, as the plurality of groups of clamping blocks 502 continue to be lowered, the cylindrical product can roll down on the mounting plate 9.
[0027] It also includes a second top block 11, and a plurality of groups of supporting blocks 12 are fixedly connected to the top of the second top block 11, and the plurality of groups of supporting blocks 12 are equidistantly arranged, and the plurality of groups of supporting blocks 12 are respectively slidably inserted into the interior of the plurality of groups of second notches 10, and the power device inside the chassis 1 provides power for the second top block 11;

A laser scanner 404 is fixedly connected to one side wall of the slider 403. The laser scanner 404 is located directly above the supporting block 12. The output shaft of the driving motor 402 drives the slider 403 on the linear slide 401 to reciprocate horizontally, thereby driving the laser scanner 404 to reciprocate horizontally, and further performing comprehensive pitch detection on the cylindrical product.
[0029] A product detection and guidance mechanism 13 is also provided on one side of the mold frame 6.

[0030] Working principle: When the utility model is used, the cylindrical product rolls downward on the sliding plate 302 until it contacts the second notch 10. At this time, the first top block 501 moves upward, thereby driving the clamping block 502 to move upward, and the cylindrical product can be lifted upward. When the clamping block 502 is flush with the top of the second notch 10, the cylindrical product can roll onto the supporting block 12, and then the second top block 11 is moved upward, thereby driving the cylindrical product on the supporting block 12 to move upward. After rising to a suitable position, the output shaft of the driving motor 402 drives the slider 403 on the linear slide 401 to perform horizontal reciprocating motion, thereby driving the laser scanner 404 to perform horizontal reciprocating motion, and then a comprehensive pitch detection of the cylindrical product can be performed.
