By setting the adhesion structure 9, the deep removal of impurities on the product surface is facilitated, and the efficiency of subsequent detection of product surface defects is further improved.
[0048] The specific arrangement and functions of the positioning structure 7, the wind blowing structure 8 and the adhesion structure 9 are described in detail below.
[0049] like Figure 1-Figure 5As shown, the side wall of the plug rod is fixedly connected with a baffle 709, and the surface of the plug rod is covered with a first spring 711, and the two ends of the first spring 711 are fixedly connected to the positioning block 707 and the baffle 709 respectively. The latch 708 will be inserted into the inner side of the slide plate 706 adjacent to the insertion hole 710 under the elastic force of the first spring 711. The surface of the conveyor belt 3 is glued with an auxiliary strip 703, and the auxiliary strip 703 is made of rubber. By providing the auxiliary strip 703, the pushing of the product is facilitated, and the phenomenon that the product is not easily pushed by the positioning plate 702 after being placed and is difficult to enter between the two positioning plates 702, which may cause subsequent products to pile up, is avoided. A V-shaped notch is provided in the middle of the auxiliary strip 703. The setting of the V-shaped groove on the auxiliary strip 703 facilitates the rapid positioning of circular plate structure products and the positioning and detection of products of different shapes.
[0050] like Figure 1-Figure 2 and Figure 6-Figure 8 As shown, the air blowing structure 8 also includes a telescopic tube 86 connected to the air duct, and a push block 87 is slidably connected to the surface of the connecting block 85, and the other end of the telescopic tube 86 is fixedly connected to the surface of the push block 87. The telescopic tube 86 will be compressed, and the air hole 89 opened at the lower side of the fixed tube 88 will spray air, thereby facilitating the preliminary cleaning of product dust and other impurities on the surface of the conveyor belt 3. The interior of the mounting block 81 is slidably connected to a slide 84 of an "L"-shaped structure. The setting of the slide 84 facilitates the pushing work of the push block 87. The outer surface of the conveyor belt 3 is glued with two rubber belts 82 made of rubber material, and the side walls of the rubber belt 82 are evenly provided with a plurality of trapezoidal grooves 83. In the process of starting the conveyor belt 3 to operate, the trapezoidal grooves 83 on the rubber belt 82 will move relative to the slide 84, and after the slide 84 moves to the inner side of the trapezoidal groove 83, the telescopic tube 86 will stretch due to its own elastic force.
[0051] like Figure 1-Figure 2 and Fig. 9 As shown, the adhesion structure 9 also includes a driving rod 92 threadedly connected to the interior of the positioning frame 91, and the driving rod 92 is rotatably connected to the interior of the push plate 94. When the driving rod 92 is rotated, the driving rod 92 will drive the push plate 94 to move up and down. A second spring 96 is fixedly connected between the round rod frame 95 and the push plate 94. By providing the second spring 96, the tightness between the double-sided adhesive tape 99 and the product is improved, which is beneficial to the subsequent removal of impurities adhered to the surface of the product. The elastic tube 98 is made of silicone. By providing the elastic tube 98, the effect of the double-sided adhesive tape 99 adhering to the surface of impurities for removal is further improved.
[0052] Working principle: before the product needs to be accurately positioned, the product is first placed at the conveying position that needs to be detected on the conveyor belt 3. At this time, pull the latch 708 first, move the slide plate 706 inside the connecting plate 701, and move the positioning plate 702 to a position close to the product surface, then release the latch 708. The latch 708 will be inserted into the inner side of the adjacent socket 710 on the slide plate 706 by the elastic force of the first spring 711. At this time, the preliminary fixing of the position of the moved positioning plate 702 can be achieved. At this time, rotate the screw rod 704, which will drive the relative movement between the positioning plate 702 and the slide plate 706, thereby achieving accurate positioning of the product. After starting the conveyor belt 3 for transmission, place the product in a position close to the surface of the auxiliary strip 703, and the product will be transported along the bending position of the two positioning plates 702, thereby In order to facilitate the positioning and detection of products, the auxiliary strip 703 is provided to facilitate the pushing of products, and the phenomenon that the products are pushed by the positioning plate 702 after being placed and are difficult to enter between the two positioning plates 702, which may easily lead to the accumulation of subsequent products, and the V-groove on the auxiliary strip 703 is convenient for the rapid positioning of circular plate structure products, and the positioning and detection of products of different shapes, and the positioning structure 7 is provided, and the position of the positioning plate 702 is adjusted twice, and the rough adjustment facilitates the rapid and rough positioning of products with large size differences, and the driving screw 704 to rotate facilitates the fine adjustment of the product positioning, thereby facilitating the rapid and accurate positioning of products with large size differences, and then facilitating the subsequent detection of products, and improving the performance of the 3D rapid AOI defect positioning equipment.
[0053] When the conveyor belt 3 is started, the trapezoidal groove 83 on the rubber belt 82 will move relative to the slide 84. After the slide 84 moves to the inner side of the trapezoidal groove 83, the telescopic tube 86 will stretch due to its own elastic force. When the slide 84 slides along the inclined surface on the inner side of the trapezoidal groove 83 to the side wall of the rubber belt 82 where the trapezoidal groove 83 is not provided, the telescopic tube 86 will be compressed. At this time, the air hole 89 provided on the lower side of the fixed tube 88 will spray air, thereby facilitating the preliminary cleaning of impurities such as dust on the surface of the product of the conveyor belt 3, avoiding the phenomenon that impurities such as hair attached to the surface of the product affect the subsequent measurement results, and further improving the measurement efficiency of product surface defects. By setting the wind blowing structure 8 and the wind blowing structure 8 that can spray air above the conveyor belt 3, the preliminary treatment of impurities such as hair on the surface of the product is facilitated, thereby improving the subsequent measurement efficiency of product surface defects.
[0054] Take out the clean double-sided adhesive tape 99, adhere the double-sided adhesive tape 99 to the surface of the elastic tube 98, rotate the driving rod 92 according to the height of the product, and the driving rod 92 will drive the push plate 94 to move up and down. When the product moves under the double-sided adhesive tape 99, the double-sided adhesive tape 99 will roll. By setting the second spring 96, the tightness between the double-sided adhesive tape 99 and the product is improved, which is beneficial to the subsequent removal of impurities adhered to the surface of the product. In addition, by rotating the driving rod 92, the tightness of the double-sided adhesive tape 99 against the surface of the product can also be adjusted. As a result, by setting the elastic tube 98, the effect of the double-sided adhesive tape 99 sticking to the surface of impurities for removal is further improved. By removing impurities from the product surface, the deep treatment of impurities on the product surface is facilitated, and it is more beneficial to the subsequent detection of product surface defects. The double-sided adhesive tape 99 can be replaced by directly tearing off the double-sided adhesive tape 99 on the outer surface of the elastic tube 98. By setting the adhesive structure 9, the deep removal of impurities on the product surface is facilitated, and the efficiency of subsequent detection of product surface defects is further improved.
