[0018] Please see Figures 1 to 2 As shown in the figure, an embodiment of this application provides a dual-channel visual inspection device, which includes a feeding mechanism 10, a discharging mechanism 20, a first conveying mechanism 30, a second conveying mechanism 40, a first inspection mechanism 50, and a second inspection mechanism 60, wherein: The first conveying mechanism 30 and the second conveying mechanism 40 are arranged in parallel and along the first horizontal direction. Figure 1 Extending in the direction of X, the feeding end of the first conveying mechanism 30 and the feeding end of the second conveying mechanism 40 are both connected to the loading mechanism 10. The loading mechanism 10 is configured to transport the products to be inspected onto the first conveying mechanism 30 and the second conveying mechanism 40. The discharging end of the first conveying mechanism 30 and the discharging end of the second conveying mechanism 40 are both connected to the unloading mechanism 20. The unloading mechanism 20 is configured to unload the products from the discharging ends of the first conveying mechanism 30 and the second conveying mechanism 40. The first inspection mechanism 50 and the second inspection mechanism 60 are spaced apart on the conveying path of the first conveying mechanism 30 and the second conveying mechanism 40. The first conveying mechanism 30 and the second conveying mechanism 40 are both configured to receive the products to be inspected conveyed by the feeding mechanism 10 and to convey the products to be inspected to the first inspection mechanism 50 and the second inspection mechanism 60 in sequence. The first inspection mechanism 50 is configured to perform visual inspection on the first surface and the second surface of the product. The second inspection mechanism 60 is configured to perform visual inspection on the side of the product that has passed through the first inspection mechanism 50.

[0019] Specifically, both the loading mechanism 10 and the unloading mechanism 20 use robotic arms to handle the products.

[0020] Specifically, the product involved in this application embodiment is a mobile phone charging port module, but it can also be other products with four or more sides.

[0021] The dual-channel visual inspection device proposed in this application sets up two independent conveying mechanisms with their infeed ends connected to the loading mechanism 10 and their discharge ends connected to the unloading mechanism 20. The conveying path of each conveying mechanism passes through the first inspection mechanism 50 and the second inspection mechanism 60 in sequence. The first inspection mechanism 50 takes pictures of the front and back of the product, and the second inspection mechanism 60 takes pictures of each side of the product. This realizes a dual-channel parallel inspection mode, which not only increases the product throughput per unit time within the mechanism, thereby improving the inspection efficiency, but also ensures a continuous inspection process and guarantees the integrity of the inspection. The two conveying mechanisms are set on the same inspection device, which has a compact structure and improves the overall space utilization of the equipment.

[0022] In one embodiment, both the first conveying mechanism 30 and the second conveying mechanism 40 are equipped with a plurality of product platforms 50, each product platform 50 carrying at least one product. The first conveying mechanism 30 is configured to convey the configured product platforms 80 to the first detection mechanism 50 and the second detection mechanism 60 along a first horizontal direction, and the second conveying mechanism 40 is configured to convey the configured product platforms 80 to the first detection mechanism 50 and the second detection mechanism 60 along the first horizontal direction.

[0023] Specifically, the product platform 80 includes a support platform 81, a base 82, and several rollers 83. The support platform 81 is disposed on the top of the base 82. Several adsorption parts 810 are disposed on the support platform 81 along the first horizontal direction. Each adsorption part 810 corresponds to a product and is used to adsorb and fix a product. At least one roller 83 is respectively installed on both sides of the base 82 extending along the first horizontal direction. The rollers 83 are rotatably disposed on the base 82 so that the sliding friction between the rollers 83 and the side wall of the corresponding first conveying channel is converted into rolling friction, thereby reducing the conveying resistance of the product platform 80.

[0024] Specifically, two rollers 53 are provided on both sides of the base 52 extending along the first horizontal direction, and the two rollers 53 on each side are spaced apart along the first horizontal direction.

[0025] Specifically, the adsorption unit 810 includes a suction cup that is connected to an external vacuum generator, providing an adsorption unit that is low-cost and provides stable and reliable adsorption.

[0026] It is evident that by configuring several product platforms 80 on the two conveyor mechanisms, each product platform 80 carries at least one product, providing stable support for the product and preventing product displacement or damage during the inspection process. At the same time, it can carry products in batches, further increasing the inspection volume per unit time, and thus further improving the working efficiency of the equipment.

[0027] In one embodiment, the dual-channel vision inspection device further includes a return conveying mechanism 70, which is arranged in parallel between the first conveying mechanism 30 and the second conveying mechanism 40. The inlet end of the return conveying mechanism 70 is connected to the outlet end of the first conveying mechanism 30 and the outlet end of the second conveying mechanism 40, and the outlet end of the return conveying mechanism 70 is connected to the inlet end of the first conveying mechanism 30 and the inlet end of the second conveying mechanism 40. The return conveying mechanism 70 is configured to receive empty product platforms 80 from the outlet ends of the first conveying mechanism 30 and the second conveying mechanism 40 and convey the received product platforms 80 toward the feeding mechanism 10. The feeding mechanism 10 is configured to transport the product to be inspected to the empty product platform 80 at the discharge end of the return conveying mechanism 70, and then transport the full product platform 80 to the first conveying mechanism 30 and the second conveying mechanism 40 via the return conveying mechanism 70.

[0028] As can be seen, by setting up a return conveyor 70 between the two conveying mechanisms and connecting it to the inlet and outlet ends of the two conveying mechanisms respectively, after the tested products are taken away from the outlet ends of the two conveying mechanisms, the return conveyor 70 transports the empty product platform 80 to the inlet ends of the two conveying mechanisms, realizing the automatic return of the product platform 80, improving the continuous operation capability of the equipment, and further improving the working efficiency of the equipment.

[0029] In one embodiment, the first conveying mechanism 30 is formed by connecting a plurality of first conveying lines 31. The plurality of first conveying lines 31 are laid on the first detection mechanism 50 and the second detection mechanism 60 along the first horizontal direction. The first conveying lines 31 are provided with channels extending along the first horizontal direction. The channels of all the first conveying lines 31 are connected to form a first conveying channel 310 for conveying the product platform 80. The second conveying mechanism 40 is formed by connecting several second conveying lines 41. The several second conveying lines 41 are laid on the first detection mechanism 50 and the second detection mechanism 60 along the first horizontal direction. The second conveying lines 41 are provided with channels extending along the first horizontal direction. The channels of all the second conveying lines 41 are connected to form a second conveying channel 410 for conveying the product platform 80.

[0030] It can be seen that by splitting the first conveying mechanism 30 and the second conveying mechanism 40 into several conveying lines, the conveying lines form a corresponding conveying channel, ensuring the accurate orientation of the product platform 80 and avoiding path errors and deviations, thereby facilitating the precise adaptation of the detection mechanism and the conveying path; at the same time, the split structure facilitates the flexible arrangement of the first detection mechanism 50 and the second detection mechanism 60, improving the applicability of the equipment.

[0031] Please see Figures 2 to 4 As shown, in one embodiment, the first conveyor line 31 and the second conveyor line 41 have the same structure. The first conveyor line 31 includes two sets of first bearing components 311, a drive component 312, and two limiting members 313, wherein: Two sets of first bearing components 311 are arranged in parallel and extend along the first horizontal direction. The first conveying channel 310 is located between the two sets of first bearing components 311. Each set of first bearing components 311 includes a number of first conveying rollers 3110 arranged at intervals along the first horizontal direction. The product platform 80 is movably arranged on the bearing surface of the corresponding first conveying roller 3110. The drive assembly 312 is located below the first conveying channel. The drive end of the drive assembly 312 is connected to two limiting members 313. The drive assembly 312 is configured to drive the two limiting members 313 to move synchronously up and down and laterally along the first horizontal direction. The two limiting members 313 are spaced apart along the first horizontal direction. The drive assembly 312 drives the limiting members 313 to rise to a high position so that the limiting members 313 are higher than the bottom surface of the product platform 80. When the two limiting members 313 are in the high position, the two limiting members 313 respectively limit the corresponding ends of the product platform 80 along the first horizontal direction. The drive assembly 312 drives the limiting members 313 to move laterally a preset distance along the first horizontal direction so as to convey the product platform 80 along the first horizontal direction.

[0032] Specifically, the first bearing assembly 311 also includes a first mounting frame 3111 and a first limiting plate 3112. The first limiting plate 3112 is vertically mounted on the first mounting frame 3111 and extends along the first horizontal direction.

[0033] Specifically, the drive assembly 312 includes a first drive member 3120, a transverse plate 3121, a lifting drive member 3122, and a lifting plate 3123. The fixed end of the first drive member 3120 is mounted on the corresponding machine base, and the driving end of the first drive member 3120 is connected to the transverse plate 3121. The first drive member 3120 is used to drive the transverse plate 3121 to move laterally in the first horizontal direction. The fixed end of the lifting drive member 3122 is mounted on the transverse plate 3121, and the driving end of the lifting drive member 3122 is connected to the lifting plate 3123. Two limiting members 313 are provided on the top surface of the lifting plate 3123, and the lifting drive member 3122 is used to drive the lifting plate 3123 to rise and fall.

[0034] Specifically, the drive assembly also includes a first mounting bracket 3124 and two sets of guide assemblies 3125. The lifting drive component 3122 is configured as a cylinder. The bottom of the first mounting bracket 3124 is fixedly mounted on the transverse plate 3121. The cylinder is mounted on the first mounting bracket 3124, with the extension end of the cylinder facing upward and connected to the lifting plate 3123. The two sets of guide assemblies 3125 are spaced apart along the first horizontal direction and the guide assemblies 3125 connect the lifting plate 3123 and the first mounting bracket 3124. The guide assemblies 3125 are used to guide the lifting of the lifting plate 3123.

[0035] Specifically, the guide assembly 3125 includes a guide post and a guide sleeve. The upper end of the guide post is fixedly connected to the lifting plate 3123, and the guide sleeve is installed on the first mounting bracket 3124 and slidably fitted onto the corresponding guide post.

[0036] Specifically, the first drive component 3120 is a linear module composed of a motor and a ball screw linear transmission pair.

[0037] Specifically, the first conveyor line 31 also includes at least two sets of second bearing components 314. The two sets of second bearing components 314 are arranged in parallel and extend along the first horizontal direction. The two sets of second bearing components 314 are arranged one-to-one with the two sets of first bearing components 311 along the first horizontal direction. The first bearing components 311 are arranged at the feed end and / or discharge end of the corresponding channel. The height of the bearing surface of the second bearing component 314 is adjustable to ensure that the product platform 80 smoothly transitions between adjacent first conveyor lines 31 or adjacent second conveyor lines 41, thereby improving conveying accuracy and connection stability.

[0038] Specifically, the second bearing assembly 314 includes a second mounting bracket 3140, a second limiting plate 3141, a fixing plate 3142, a locking bolt 3143, and a plurality of second conveying rollers 3144. The second limiting plate 3141 is vertically fixedly mounted on the second mounting bracket 3140 and extends along the first horizontal direction. The plurality of second conveying rollers 3144 are rotatably mounted on the second mounting bracket 3140 at intervals and are located on the side of the second limiting plate 3141 near the first conveying channel 310. The fixing plate 3142 is fixedly mounted on the equipment frame. The fixing plate 3142 has a vertically extending oblong hole. The second limiting plate 3141 has a threaded hole. The locking bolt 3143 passes through the oblong hole and is locked in the threaded hole to fix the second limiting plate 3141 on the inner side of the fixing plate 3142. The structure is simple and easy to operate.

[0039] As can be seen, by setting up a first conveying channel 310 with conveying rollers at the bottom, the friction of the product platform 80 is reduced. At the same time, the limit member 313 is driven to rise and fall and move laterally by a plug-in drive method. When the limit member 313 is in a high position, it limits the product platform 80 and drives its conveying, thus realizing the stable conveying of the product platform 80. At the same time, it ensures the accurate orientation of the product platform 80, avoids path errors and deviations, and improves the accuracy of repeated positioning.
