Detailed Implementation

[0024] The specific embodiments of the present invention 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 present invention.

[0025] In this invention, 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 normal use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0026] See Figure 1-5 As shown, this invention provides a 3D line scan detection flatness detection device, including first support platforms 1 symmetrically arranged on both sides of a transmission line 11; lifting cylinder plates 2 are provided on the first support platforms 1, and the two lifting cylinder plates 2 are connected by a detection unit; wherein, the detection unit includes a rectangular frame 3, and a sliding plate 4 is provided inside the rectangular frame 3, which slides along the width direction parallel to the transmission line 11; the first end of the sliding plate 4 is elastically connected to the rectangular frame 3, and a push plate 6 is fixedly connected to the upper surface of the second end of the sliding plate 4; the rectangular frame 3 near the sliding plate 4... A motor 8 is provided at the second end position, and a cam 7 is provided on the shaft of the motor 8 to contact the push plate 6; a groove 23 is provided on the bottom side of the slide plate 4, and multiple columns 20 are arranged in a matrix in the groove 23. A pressure detection pad 19 is provided on the bottom surface of the groove 23 and sleeved on the column 20; a movable sleeve 22 is sleeved on the lower end of the column 20, and a first spring 21 is sleeved on the column 20. The two ends of the first spring 21 are respectively connected to the pressure detection pad 19 and the movable sleeve 22; the lower end of the movable sleeve 22 protrudes from the bottom surface of the rectangular frame 3.

[0027] By implementing the above technical solution, an upper plane detection mechanism 17 is set on the transmission line 11. The upper plane detection mechanism 17 can continuously detect the flatness of the upper plane 9 of the workpiece during transmission. When the detected upper plane 9 of the workpiece has unevenness such as depressions or protrusions, the compression degree of the first spring 21 will change, and the pressure value of the first spring 21 on the pressure detection pad 19 will change. Thus, the flatness of the upper plane 9 of the workpiece can be determined based on the pressure value collected in real time on the pressure detection pad 19. In addition, the motor 8 drives the cam 7 to rotate, which drives the slide plate 4 to move back and forth within the rectangular frame 3. With the movement of the transmission line 11, each movable sleeve 22 is attached to the upper plane 9 of the workpiece in a straight sinusoidal path scan, thereby increasing the comprehensiveness of the detection coverage. Finally, the multiple movable sleeves 22 arranged in a matrix can improve the detection efficiency and reduce the detection time.

[0028] In this embodiment, to further provide a planar surface detection mechanism 18 for detecting the flatness of the planar surface 10 of a workpiece, a second support platform 13 is provided on the left and / or right side of the transmission line 11. A corner groove is provided on the outer side of the second support platform 13, and a first movable block 14 that moves parallel to the width direction of the transmission line 11 is provided within the corner groove. A second movable block 15 that moves vertically is connected to the first movable block 14, and the detection unit is rotatably connected to the second movable block 15 via a self-driving shaft 24. See also... Figure 1 and Figure 2 As shown, the lateral and height positions of the detection unit can be adjusted via the first movable block 14 and the second movable block 15, and the tilt angle of the detection unit can be adjusted via the self-driven rotating shaft 24. This allows for the detection of the flatness of the inclined plane 10 of the workpiece at different positions and angles. The detection process and principle are the same as those of the upper plane detection mechanism 17, and will not be repeated here. The bottom of the detection unit is equipped with a connecting piece 16 that is rotatably connected to the self-driven rotating shaft 24, which is similar to the shaft of the angle motor 8.

[0029] In this embodiment, to further provide a movable connection method between the first movable block 14 and the second movable block 15, a first telescopic rod 25 is provided between the first movable block 14 and the inner wall of the corner groove, and a second telescopic rod is provided between the first movable block 14 and the second movable block 15. The first telescopic rod 25 and the second telescopic rod are pneumatic or hydraulic rods.

A third telescopic rod is disposed within each of the second springs 5, and the two ends of the third telescopic rod are respectively connected to the slide plate 4 and the rectangular frame 3. The slide plate 4 is driven to move by the cam 7 and then reset by the second springs 5, causing the slide plate 4 to reciprocate. The third telescopic rod only serves for extension, retraction, and positioning and does not have a power source.

[0031] In this embodiment, the lower end of the movable sleeve 22 is spherical. The spherical shape reduces scratches on the workpiece surface and facilitates the transition of the movable sleeve 22 to the edge of the workpiece surface, preventing it from getting stuck on the outside of the workpiece.

[0032] In this embodiment, a plurality of positioning slots 12 are arranged on the transmission line 11. The positioning slots 12 can effectively locate the position of the workpiece, facilitate the inspection operation, and improve the accuracy of the inspection.

[0033] In this embodiment, the rectangular frame 3 has grooves on both sides, and the slide plate 4 has sliding ribs on both sides that slide within the grooves. This makes the reciprocating sliding of the slide plate 4 more stable.

[0034] Furthermore, another aspect of the present invention provides an automated production packaging device, which includes the aforementioned 3D line scan flatness detection device; robotic arms are provided on both sides of the end of the transmission line 11, the robotic arms being used to pick up unqualified products and place them in the defective product area, and to place qualified products in the packaging line.

[0035] This automated production and packaging device can connect flatness inspection with the packaging line, thereby improving the pass rate of packaged products.
