[0002] A circuit board is composed of integrated circuits, crystal oscillators, trimming capacitors, and printed circuit boards, and is mainly used to connect various electronic components in electronic devices and serve as a structural support. During the circuit board processing, dot digging and blackening are required, so a full-automatic dot digging and blackening machine is needed, and the dot digging and blackening machine needs to use a visual detection device to detect the circuit board after dot digging and blackening.

The connecting block 7 has an "I" - shaped structure, and card slots 8 are opened on both sides of the connecting block 7. A cross rail 10 is arranged on the upper side of the bottom plate 1, and a moving seat 11 is installed above the cross rail 10, and a bearing plate 12 is fixed on the upper side of the moving seat 11; The movement of the moving seat 11 on the cross rail 10 facilitates driving the movement of the bearing plate 12, so that the bearing plate 12 can feed the circuit board to be detected. The industrial camera 6 is convenient for visually detecting the dot-digging and blackening situation of the circuit board, and then eliminating the circuit boards with unqualified dot-digging and blackening.

[0021] As Figure 2 - Figure 3As shown, the installation component 5 includes a bidirectional lead screw 501, a moving sleeve 502, a moving plate 503, and a clamping block 504. The bidirectional lead screw 501 is rotatably connected to the installation frame 4, and moving sleeves 502 are symmetrically sleeved on the outer side of the bidirectional lead screw 501. A moving plate 503 is fixed to the lower side of the moving sleeve 502, and a clamping block 504 is fixed to one side of the moving plate 503. The installation component 5 further includes a driving motor 505. The driving motor 505 is installed on the outer side of one side of the installation frame 4, and the output shaft of the driving motor 505 is fixedly connected to the bidirectional lead screw 501. The moving sleeve 502 is slidably connected to the installation frame 4, and the clamping block 504 is snap-fitted with the card slot 8. By means of the driving motor 505, it is convenient to drive the rotation of the bidirectional lead screw 501, and then drive the relative movement of the two moving sleeves 502 on its outer side, so that the distances between the moving sleeves 502, the moving plates 503, and the clamping blocks 504 on both sides are adjustable. Thus, the clamping block 504 of the moving plate 503 can be snap-fitted with the card slots 8 on both sides of the "I"-shaped connecting block 7, and then the industrial camera 6 can be conveniently installed. On the contrary, moving away from the moving plates 503 and the clamping blocks 504 on both sides can facilitate the disassembly of the industrial camera 6. There is no need to use bolts for disassembly and assembly, and it is flexible and convenient to replace the industrial camera 6.

[0022] As Figure 2 - Figure 3 shown, a stable anti-shake component 9 is installed below the moving plate 503. The stable anti-shake component 9 includes a side plate 901, an electric telescopic rod 902, a positioning plate 903, and a rubber layer 904. The side plate 901 is fixed to the outer side below one side of the moving plate 503, and the electric telescopic rod 902 is installed inside the lower side of the side plate 901. One end of the electric telescopic rod 902 is fixed to the positioning plate 903, and a rubber layer 904 is bonded to the side surface of the positioning plate 903. The stable anti-shake component 9 further includes an adjustable support plate 905. The adjustable support plate 905 is slidably installed below the outer side surface of the positioning plate 903, and the adjustable support plate 905 is bolted to the positioning plate 903, and the adjustable support plate 905 is in an "L" shape. By means of the electric telescopic rods 902 on both sides, it is convenient to expand and contract to adjust the positions of the two positioning plates 903, so that the positioning plates 903 and the rubber layers 904 on both sides can position and clamp the outer sides of the industrial camera 6. And the position of the adjustable support plate 905 can be adjusted up and down and locked by bolts, which is suitable for industrial cameras 6 of different sizes, so that the adjustable support plate 905 in an "L" shape can support the lower sides of the industrial camera 6, thereby improving the stability of the industrial camera 6 during operation, avoiding the situation that the image acquisition and visual detection effects are poor due to the jitter of the industrial camera 6 during operation, and thus being beneficial to improving the detection accuracy.

[0023] In summary, as Figure 1 - Figure 3As shown in the figure, for the vision detection device of the circuit board dot-digging and blackening machine, during use, first, the circuit board to be detected can be set on the upper side of the carrier plate 12. Then, the movement of the carrier plate 12 can be driven by the movement of the moving seat 11 on the cross rail 10, so that the carrier plate 12 can feed the circuit board to be detected. When it moves to the lower side of the industrial camera 6, the industrial camera 6 can be used to conduct vision detection on the dot-digging and blackening situation of the circuit board, and then the circuit boards with unqualified dot-digging and blackening can be removed. During the use of the industrial camera 6, when disassembly and maintenance are required, it can be supported and the rotation of the bidirectional lead screw 501 can be driven by the driving motor 505. Furthermore, the relative movement of the two moving sleeves 502 on its outer side can be driven, so that the moving sleeves 502, moving plates 503 and clamping blocks 504 on both sides move away, which is convenient for the disassembly of the industrial camera 6. On the contrary, during installation, the clamping block 504 of the moving plate 503 can be engaged with the clamping grooves 8 on both sides of the "I"-shaped connecting block 7, which can facilitate the installation of the industrial camera 6. In addition, the positions of the two adjustment positioning plates 903 can be adjusted by the telescopic movement of the electric telescopic rods 902 on both sides, so that the positioning plates 903 and rubber layers 904 on both sides can position and clamp the outer sides of the industrial camera 6. Moreover, the position of the adjustable support plate 905 can be adjusted up and down and locked by bolts, so as to support the lower sides of the industrial camera 6 through the adjustable support plate 905 with an "L"-shaped structure, thereby improving the stability of the industrial camera 6 during operation and avoiding the situation that the image acquisition and vision detection effects are poor due to the shaking of the industrial camera 6 during operation. In this way, the use process of the vision detection device of the circuit board dot-digging and blackening machine is completed.
