Detailed Implementation

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0020] See Figure 1-6 The point laser fixture shown includes a bracket and a support block 4 mounted on the upper end of the bracket. The support block 4 has multiple U-shaped openings 6 on its front and rear sides. A point laser sensor 11 is mounted on the bracket at the U-shaped openings 6. The emitter 5 of the point laser sensor 11 is vertically upward. Multiple limiting posts 10 are mounted on the upper surfaces of the first and second adjacent sides of the support block 4. Multiple limiting sliders 7 that can be fastened by screws are mounted on the third and fourth adjacent sides of the support block 4. The first and third sides are arranged opposite each other, and the second and fourth sides are arranged opposite each other.

[0021] By implementing the above technical solution, when inspecting product 13, the product 13 is transported to the support block 4 by the gripper on the robotic arm. The first and second sides of product 13 are limited by the limiting posts 10, and the third and fourth sides are limited by the limiting sliders 7. After being placed in place, multiple point laser sensors 11 are activated to emit detection beams toward the bottom surface of product 13 to be inspected. The distance from the detection area to the transmitter head 5 is measured. By collecting the distances of multiple detection areas, it is determined whether product 13 is qualified, thereby realizing rapid and automated inspection of product 13. Through the automated inspection process, the inspection efficiency and consistency of product 13 can be effectively improved, the misjudgment caused by human factors can be reduced, and the labor intensity of operators can be reduced.

[0022] In this embodiment, to further provide a support structure, the support includes a base plate 1, a column 2, and a top plate 3 connected in sequence. The top plate 3 has a rectangular hole 12 for mounting the point laser sensor 11. A right-angle plate is installed within the rectangular hole 12, and the vertical panel 15 of the right-angle plate extends into the rectangular hole 12, where the point laser sensor 11 is mounted with bolts. By using the rectangular hole 12 and the right-angle plate to mount the point laser sensor 11, the position of the point laser sensor 11 is lowered, facilitating detection.

[0023] In this embodiment, the support block 4 includes multiple unit supports, which are mounted on the top plate 3 by screws. With this arrangement, each support unit has multiple countersunk holes through which screws pass and are screwed onto the top plate 3, facilitating assembly and disassembly.

[0024] In this embodiment, the limiting slider 7 is provided with a waist hole 14, and the support block 4 is provided with a slide groove for the limiting slider 7 to slide. The bottom surface of the slide groove is provided with a screw hole 16 corresponding to the waist hole 14. The direction of the waist hole 14 is set horizontally and vertically along the support block 4, and is used to adjust the limiting position for products 13 of different specifications. After the limiting slider 7 is adjusted to the position along the slide groove, a screw is used to pass through the waist hole 14 and screw it into the screw hole 16 for tightening.

[0025] In this embodiment, the upper surface of the support block 4 is a curved surface that bends in the left-right direction. This configuration creates a contour-following structure, allowing the upper surface of the support block 4 to fit snugly against the bottom surface of the product 13, thus reducing measurement deviations caused by the surface of the support block 4.

[0026] In this embodiment, a heightening pad 8 is provided between the flat plate 9 of the right-angle plate and the top plate 3. This arrangement ensures that the higher and lower positions of the measuring part are at similar heights from the laser sensor 11, facilitating data analysis.

[0027] In this embodiment, for a product 13 that bends laterally, the thickness of the heightening pad 8 gradually decreases from the middle towards both ends. The heightening pad 8 may not be used at the ends.
