Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to an automatic optical detection device for the flatness of the cross section of a cut small piece. Background Art

[0002] In the field of mechanical processing, the requirements for the processing accuracy of small products are becoming increasingly stringent. Among them, the flatness of the end faces of small parts, as a key indicator affecting product quality and performance, has received widespread attention. Taking electronic equipment manufacturing as an example, the flatness of the end faces of many small precision parts inside directly determines the stability and service life of the equipment.

[0003] The traditional method of detecting the flatness of the end surface of small parts mainly relies on manual operation. During manual inspection, workers use simple tools such as micrometers and feeler gauges for measurement. This method is not only inefficient, but also takes several minutes or even longer to detect a small part, which is difficult to meet the inspection needs of large-scale production. In addition, the inspection results are easily affected by the subjective factors of workers. There are differences in the operating methods and judgment standards of different workers, resulting in poor accuracy and consistency of the inspection results, and false detection and missed detection often occur.

[0004] In order to improve the detection efficiency, some companies have many shortcomings in the existing optical detection devices when testing small parts. Some devices cannot achieve stable clamping of small parts. During the detection process, small parts are prone to displacement or shaking, resulting in large deviations in the detection results. Although other devices can clamp small parts, the clamping method is complicated, the operation is inconvenient, and they cannot adapt well to small parts of different sizes and shapes. In addition, it is difficult for existing optical detection devices to achieve an ideal balance between detection accuracy and detection speed. Therefore, it is necessary to design an automatic optical detection device for the flatness of the cross-section of cut small parts. Summary of the invention

[0005] In order to overcome the shortcomings that the results of manual inspection are easily affected by workers' subjective factors and the unstable clamping of small parts by existing optical inspection devices, the technical problem of the present invention is to provide an automatic optical inspection device for the flatness of the cross-section of cut small parts.

The ball nut is connected to the top block.

[0010] Furthermore, particularly preferably, the limiting assembly includes a first screw rod, a top plate and a rotating head. First screw rods are rotatably arranged on the front and rear sides of the moving limiting plate, the top ends of the two first screw rods are rotatably connected to the adjacent side of the bottom of the top plate, and rotating heads are arranged at the bottom of the two first screw rods.

Generally speaking, the device has a simple structure, greatly facilitating the detection operation and improving the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0022] The technical solution of the present invention will be further described below in conjunction with the attached drawings.

[0023] Example 1: An automatic optical detection device for the flatness of the cross-section of small pieces to be cut, as Figures 1 - 4As shown in the figure, it includes a base 1, a lifting table 2, a laser 3, a support table 4, a sliding frame 5, a mounting plate 6, a rectangular frame 7, a first lead screw 8, a rotating motor 9, an adjusting component 10, a clamping component 11, a limiting component 12 and a display board 13.

A rotating motor 9 is arranged on the left side of the support table 4. The output shaft of the rotating motor 9 is connected to the first lead screw 8. An adjusting component 10 capable of supporting the bottom of the small cutting piece is arranged on the sliding frame 5. The adjusting component 10 includes a mounting seat 101, a second lead screw 102, a ball nut 103, a rotating sleeve 104, a belt transmission component 105, a cylinder block 106, a piston rod 107, a connecting frame 108, an airbag 109 and a hose 1010. Mounting seats 101 are symmetrically arranged on the front and rear side walls of the sliding frame 5. A second lead screw 102 is rotatably arranged on the mounting seat 101. A ball nut 103 is screwed on the second lead screw 102. Rotating sleeves 104 are arranged at the left ends of the two second lead screws 102. A belt transmission component 105 is arranged between the left ends of the two second lead screws 102. Cylinder blocks 106 are arranged on the front and rear side walls of the sliding frame 5. A piston rod 107 is slidably arranged in the cylinder block 106. The piston rod 107 is composed of a push rod and a piston. The piston is slidably matched with the cylinder block 106. The piston rod 107 is connected to the adjacent ball nut 103 through a connecting frame 108. An airbag 109 is embedded in the rectangular frame 7. Hoses 1010 are communicated with the right sides of the cylinder blocks 106. The hoses 1010 are communicated with the airbag 109. A clamping component 11 capable of fixing the side wall of the small cutting piece is arranged on the adjusting component 10. The clamping component 11 includes a fixed limiting plate 111, a fixed block 112, a moving rod 113, a moving limiting plate 114, a top block 115 and an elastic member 116. A fixed limiting plate 111 is arranged on the right side of the rectangular frame 7. Fixed blocks 112 are symmetrically arranged on the front and rear sides of the left side wall of the rectangular frame 7. A moving rod 113 is arranged on the fixed block 112. A moving limiting plate 114 is slidably arranged between the two moving rods 113. Top blocks 115 are slidably arranged on the two moving rods 113. An elastic member 116 is arranged between the top block 115 and the moving limiting plate 114. The ball nut 103 is connected to the top block 115. A limiting component 12 capable of fitting the top of the small cutting piece is arranged on the clamping component 11.The limiting component 12 includes a first screw rod 121, a top plate 122 and a rotating head 123. The first screw rods 121 are rotatably arranged on both the front and rear sides of the moving limiting plate 114. The tops of the two first screw rods 121 are rotatably connected to the bottom of the top plate 122 near one side. The bottoms of the two first screw rods 121 are both provided with rotating heads 123. A display board 13 is arranged on the left side of the top of the mounting plate 6.

[0024] When the device needs to be used, the staff first adjusts the height of the lifting plate 202 of the lifting platform 2 and then fixes it with the fastening bolt 203. Then the staff places the small cutting pieces to be inspected at intervals in the rectangular frame 7. One side of the small cutting piece contacts the fixed limiting plate 111. By rotating the rotating heads 123 on both the front and rear sides, the rotating head 123 drives the first screw rod 121 to rotate, and the first screw rod 121 drives the top plate 122 to move downward to contact the top of the small cutting piece. Then rotate the rotating sleeve 104. The rotating sleeve 104 is transmitted through a pulley and a flat belt, so as to realize the synchronous rotation of the two second screw rods 102. The second screw rod 102 drives the ball nut 103 to move to the right. The ball nut 103 squeezes the gas in the cylinder 106 into the airbag 109 through the piston rod 107. The airbag 109 is inflated to lift the bottom of the small cutting piece, so that the small cutting piece is in close contact with the top plate 122. At the same time, when the ball nut 103 moves, it will drive the top block 115 to move to the right, and the top block 115 and the elastic member 116 move the limiting plate 114 to move to the right, which can squeeze and fix the side wall of the small cutting piece. Then start the laser 3 to irradiate blue light on the display board 13. The position of the sliding frame 5 can be adjusted by starting the rotating motor 9, and the rotating motor 9 drives the first screw rod 8 to rotate, which is beneficial to adjusting the clarity of the projection formed by the irradiation of the laser 3. By observing whether there is light leakage between the top plate 122 and the small cutting piece on the display board 13, the flatness of the end face of the small cutting piece can be quickly detected. The structure of this device is simple and easy to operate.

[0025] Embodiment 2: On the basis of Embodiment 1, as Figure 2 and Figure 5 shown, it further includes an auxiliary irradiation component 14. The auxiliary irradiation component 14 includes an annular frame 141, an annular lamp 142, a second screw rod 143 and an arc-shaped clamping block 144. An annular lamp 142 is arranged on the annular frame 141. The second screw rods 143 are screwed on the annular frame 141 at intervals. The ends of the second screw rods 143 close to the center of the annular frame 141 are both provided with arc-shaped clamping blocks 144. The annular frame 141 is clamped and fixed at the head position of the laser 3 through the arc-shaped clamping blocks 144.

[0026] As Figure 1 and Figure 6As shown, it further includes an occlusion component 15. The occlusion component 15 includes a rotating shaft 151 and a baffle 152. The rotating shafts 151 are arranged at the front and rear of the left side of the top of the base 1, and the baffle 152 is arranged on the rotating shafts 151.

[0027] The baffle 152 blocks other stray light. The outer ring of the workpiece is evenly illuminated by the white light of the annular lamp 142, which can be used as a reference boundary, avoiding visual errors caused by insufficient light, helping to more accurately judge the reflection situation and position of the laser on the surface of the workpiece, assisting the operator to more accurately determine the position of the laser irradiation area on the workpiece, facilitating the comparison of the laser reflection situations of different parts, thus more intuitively discovering the differences in the flatness of the workpiece surface, and further enabling the blue light irradiated on the display board 13 to be more obvious.

[0028] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
