DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-4 As shown, a double-sided recognition device for visual recognition includes a base 1 and a conveyor belt 2, the conveyor belt 2 is installed on the upper side of the base 1, a plurality of evenly distributed carrying trays 3 are installed on the upper side of the conveyor belt 2, a placing frame 4 is opened inside the carrying tray 3, and a double-sided recognition mechanism is installed in the middle of the conveyor belt 2;

[0020] The double-sided recognition mechanism includes a slide bar 5, which is fixedly connected to the base 1. A movable bracket 6 is installed on the upper side of the slide bar 5 for sliding left and right. An industrial camera 7 is installed on the upper side of the movable bracket 6. There are two industrial cameras 7, which are respectively located on the upper and lower sides of the carrying tray 3. A synchronization component for controlling the movement of the movable bracket 6 is installed on the side of the movable bracket 6.

[0021] When the utility model is in use, the product to be identified is placed from the right side of the conveyor belt 2 on the inner side of the placement frame 4 on the upper side of the carrying tray 3, and the industrial cameras 7 on the upper and lower sides of the carrying tray 3 simultaneously identify the front and back sides of the product placed on the inner side of the carrying tray 3, and the synchronization component controls the movable bracket 6 to move left and right, so as to achieve synchronization with the rotation speed of the conveyor belt 2 during identification.

[0022] The synchronization component cooperates with the movable bracket 6 that slides left and right so that when the equipment is identifying the product, the industrial camera 7 can be relatively still with the carrying tray 3, avoiding the occurrence of dynamic blur, thereby improving the recognition accuracy of the equipment and improving the inspection quality of the product. At the same time, the synchronization component and the movable bracket 6 can also enable the conveyor belt 2 to continue to operate during inspection, thereby improving inspection efficiency.

[0023] There are two groups of synchronization components and they are symmetrically distributed front to back. The synchronization components include a sliding sleeve 8, which is fixedly installed on the side of the movable bracket 6. A synchronization rod 9 is slidably installed on the inner side of the sliding sleeve 8, and a baffle 10 is fixed in the middle of the synchronization rod 9. A fixing ring 11 fixed to the movable bracket 6 is sleeved on the outer side of the synchronization rod 9, and a first return spring 12 is installed between the fixing ring 11 and the baffle 10. A guide wheel 13 is installed on the outermost side of the synchronization rod 9 for vertical rotation, and a fixed triangle block 14 fixedly connected to the base 1 and matching the guide wheel 13 is installed on the left side of the guide wheel 13. A second return spring 15 is installed on the outer side of the sliding rod 5, and the second return spring 15 is located on the left side of the movable bracket 6. A fixed column 16 matching the synchronization rod 9 is installed on the upper side of the carrying tray 3.

[0024] When the conveyor belt 2 is running, the synchronization rod 9 abuts against the left side of the fixed column 16 and is driven by the conveyor belt 2 to move to the left. When it reaches the specified position, the guide wheel 13 abuts against the fixed triangle block 14, causing the fixed rod to move forward, backward and outward. At this time, the synchronization rod 9 is separated from the fixed column 16, and under the action of the second reset spring 15, the movable bracket 6 is pushed as a whole to the starting position on the right side of the slide bar 5. The first reset spring 12 and the baffle 10 reset the synchronization rod 9 again and abut against the fixed rod on the upper side of the next carrying tray 3 for the next identification, and this cycle is repeated.

[0025] The cooperation of the synchronization rod 9, the guide wheel 13 and the triangular rod enables the synchronization component to automatically control the movement of the movable bracket 6 according to the rotation of the conveyor belt 2, ensuring that the industrial camera 7 is synchronized with the carrying tray 3 when the conveyor belt 2 is operating without consuming external energy, thereby reducing the operating cost of the equipment.

[0026] A release assembly is also provided on the upper side of the carrying tray 3, and the release assembly includes four placement rods 17. The placement rods 17 are arranged in groups of two and are respectively located on the front and rear sides of the placement frame 4, and are slidably connected to the carrying tray 3 front and back. Two control rods 18 distributed in a front and rear circumference are installed on the inner side of the carrying tray 3. The two control rods 18 are slidably connected to the carrying tray 3 front and back, and are respectively transmission-connected to the two groups of placement rods 17 front and back. A tensioning spring 19 is installed between the control rod 18 and the inner wall of the carrying tray 3. Two control arms 20 are slidably installed on the front and rear sides of the carrying tray 3, and the control arms 20 are respectively transmission-connected to the two control rods 18. A rotating wheel 21 is rotatably installed on the outer side of the control arm 20, and a sorting assembly matching the rotating wheel 21 is installed on the left side of the base 1.

[0027] When the release component is not working, the tensioning spring 19 is in a compressed state, and the control rod 18 makes the placement rod 17 located inside the placement frame 4. The products to be inspected are placed inside the placement frame 4 and located on the upper side of the placement rod 17. When qualified products are identified by the identification mechanism, the sorting component can control the control arm 20 to squeeze inward. At this time, the placement rod 17 shrinks toward the inside of the carrying tray 3 and releases the product. The release component can achieve sorting by releasing qualified or unqualified products.

[0028] The sorting component includes a funnel 22, which is installed on the lower side of the carrying tray 3 located on the upper side and fixedly connected to the base 1. Two columns 23 distributed front and back are vertically installed on the upper side of the funnel 22. A movable triangular block 24 matching the rotating wheel 21 is slidably installed up and down in the middle of the column 23. A cross frame 25 is installed on the top of the column 23. An electric telescopic rod 26 is vertically installed in the middle of the cross frame 25. The output end of the electric telescopic rod 26 is transmission-connected to the movable triangular block 24.

[0029] When the tray 3 loaded with qualified products is located on the upper side of the funnel 22, the electric telescopic rod 26 is in a retracted state. At this time, the products inside the placement frame 4 are safely transferred to the left side of the conveyor belt 2 and discharged from the left side. When the unqualified products pass through the upper side of the funnel 22, the electric telescopic rod 26 extends, so that the movable triangular block 24 abuts against the rotating wheel 21 to squeeze the control arm 20 inward, so that the release component releases the product, and the unqualified products are discharged from the funnel 22.

[0030] The electric telescopic rod 26 and the movable triangle plate can realize automatic screening of products, while improving the convenience of use and the functionality of the equipment.

[0031] A buffer rubber pad 27 matching the movable bracket 6 is installed on the right side of the synchronization rod 9 .

[0032] The buffer rubber pad 27 can buffer the movement when the movable bracket 6 is reset under the action of the second reset spring 15, thereby protecting the double-sided recognition mechanism and extending its service life.

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
