DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The preferred implementation of the utility model is now further described in conjunction with the accompanying drawings. Figure 1 As shown, the probe automatic optical inspection machine includes a conveying mechanism 10, on which a vibrating loading tray 100, a first optical dimension measuring mechanism 200, a multi-angle optical appearance defect detection mechanism 300 and a dividing mechanism 400 are sequentially arranged. The probe to be inspected is firstly arranged on the vibrating loading tray 100, and then the vibrating loading tray 100 is vibrated to send the probe to the conveying mechanism 10, and then the product size is measured by the first optical dimension measuring mechanism 200, and then the first side surface, the second side surface, the top surface 45 degrees and the bottom surface of the probe are inspected for appearance defects by the multi-angle optical appearance defect detection mechanism 300, and then the probes that have passed the appearance defect detection are distinguished by the dividing mechanism 400, and good products and defective products are classified and summarized. Compared with the prior art, the present application changes the traditional method of observing the probe with the workers' eyes to automatic measurement and observation using automated assembly line equipment by setting up a first optical dimension measuring mechanism 200, a multi-angle optical appearance defect detection mechanism 300 and a material dividing mechanism 400. Since the probe is an extremely small product in this field, the above improvements greatly shorten the detection time of the probe and improve the detection accuracy of the probe, thereby greatly improving the production efficiency of the enterprise and saving labor costs.

[0029] On the basis of the above embodiments, Figure 1 and Figure 2As shown, the conveying mechanism 10 is arranged on a workbench 20, and the transmission mechanism includes an annular conveyor belt 11 connected end to end, a support base 12 is arranged at the bottom of the annular conveyor belt 11, and a rotating motor 13 is arranged at the bottom of the support base 12. The rotating motor 13 can drive the support base 12 to rotate, thereby driving the annular conveyor belt 11 to rotate.

[0030] The vibrating loading tray 100 is arranged on one side of the circular conveyor belt 11. The vibrating loading tray 100 includes a vibrating plate 110 and a loading channel 120. The height of the vibrating plate 110 is higher than the circular conveyor belt 11. The loading channel 120 is used to connect the vibrating plate 110 and the circular conveyor belt 11. In an initial state, the probe is configured on the vibrating plate 110, and then the vibration effect of the vibrating plate 110 is used to send the probe to the loading channel 120, and then the height difference is used to send the probe to the circular conveyor belt 11.

[0031] Combination Figure 1 and Figure 3 As shown, the first optical dimension measuring mechanism 200 includes a first optical camera 210 and a first illumination aperture 220. The first optical camera 210 is arranged at the bottom of the circular conveyor belt 11. In this embodiment, the circular conveyor belt 11 is made of transparent material, so the first optical camera 210 can optically measure the size of the probe from the bottom through the circular conveyor belt 11. Compared with arranging the first optical camera 210 in other directions, arranging the first optical camera 210 at the bottom of the circular conveyor belt 11 can reduce the influence of other backgrounds on the optical dimension measurement. The first illumination aperture 220 is set between the first optical camera 210 and the circular conveyor belt 11.

[0032] Combination Figure 1 , 4 As shown in Figure 5, the multi-angle optical appearance defect detection mechanism 300 includes a first side appearance defect detection device 310, a second side appearance defect detection device 320, a top 45-degree appearance defect detection device 330 and a bottom appearance defect detection device 340. The structures of the first side appearance defect detection device 310, the second side appearance defect detection device 320, the top 45-degree appearance defect detection device 330 and the bottom appearance defect detection device 340 are the same, and all include a second optical camera 301 and a lighting device 302. The lighting device 302 is arranged between the second optical camera 301 and the circular conveyor belt 11.

[0033] On the basis of the above embodiments, Figure 1As shown, the first side appearance defect detection device 310 and the second side appearance defect detection device 320 are respectively arranged on the outer side and the inner side of the circular conveyor belt 11, so that the first side appearance defect detection device 310 and the second side appearance defect detection device 320 can respectively perform visual inspection of appearance defects on the outer side and the inner side of the probe from different angles. Preferably, the first side appearance defect detection device 310 and the second side appearance defect detection device 320 should be staggered relative to the circular conveyor belt 11 to avoid mutual influence between the two during visual inspection.

[0034] On the basis of the above embodiments, Figure 5 As shown, the top 45-degree appearance defect detection device 330 is set on the top of the circular conveyor belt 11 and presents a 45-degree angle with the reference plane of the circular conveyor belt 11, so that the probe can be visually inspected from the top oblique angle of the probe. Preferably, the number of the top 45-degree appearance defect detection devices 330 is two, so that the probe can be visually inspected from more oblique angles, thereby improving the accuracy of visual inspection.

[0035] On the basis of the above embodiments, Figure 1 and Figure 7 As shown, the bottom appearance defect detection device 340 is arranged at the bottom of the endless conveyor belt 11, so that the bottom appearance defect detection device 340 can perform visual inspection on the probe from the bottom of the probe.

[0036] Preferably, Figure 7 As shown, the present embodiment is further provided with a second optical dimension measuring mechanism 500, which is arranged between the top 45-degree appearance defect detection device 330 and the bottom appearance defect detection device 340. The structure of the second optical dimension measuring mechanism 500 is the same as that of the first optical dimension measuring mechanism 200, and is also arranged at the bottom of the circular conveyor belt 11, so that the accuracy of the probe dimension measurement can be ensured through two optical dimension measurements.

[0037] Combination Figure 1 and Figure 6As shown, the material separation mechanism 400 includes a good product separation device 410 and a defective product separation device 420, both of which have the same structure, and both include a push motor 401, a material separation channel 402 and a material trough 403. The push motor 401 is arranged on the inner side of the circular conveyor 11, the material separation channel 402 is arranged on the outer side of the circular conveyor 11, and the material trough 403 is arranged at one end of the material separation channel 402, and the height of the material trough 403 is lower than the height of the circular conveyor 11. When the optical size measurement mechanism and the multi-angle optical appearance defect detection mechanism 300 detect that there are defective products on the circular conveyor 11, and the defective probe moves to the circular conveyor When the conveyor belt 11 reaches the preset position, an electrical signal is sent to the pushing motor 401, which is started to push the probe to the material distribution channel 402, and then the probe is collected into the material trough 403 by utilizing the height difference. When the optical dimension measurement mechanism and the multi-angle optical appearance defect detection mechanism 300 do not detect the existence of defective products on the circular conveyor belt 11, and the probe of good products moves to the preset position of the circular conveyor belt 11, an electrical signal is sent to the pushing motor 401, which is started to push the probe to the material distribution channel 402, and then the probe is collected into the material trough 403 by utilizing the height difference, thereby completing the separation of good products and defective products on the probe.

[0038] The above exemplary embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
