Detailed Description of the Preferred Embodiments
[0020] The following will further illustrate the utility model with specific embodiments. It should also be noted that unless otherwise clearly defined and limited, terms such as: set, install, connect, and couple should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.
[0021] Embodiment: A device for identifying and correcting the front and back of products based on a CCD camera, as Figure 1As shown in the figure, it includes a first roller conveyor 1, a turning conveyor 2, a second roller conveyor 3, a flipping mechanism and a CCD camera 5. The first roller conveyors 1 are arranged on both the left and right sides of the turning conveyor 2, and the second roller conveyor 3 is arranged at the rear of the turning conveyor 2. The turning conveyor 2 includes a frame 21, a belt conveying assembly and a lifting conveying assembly. The CCD camera 5 is installed on the left side of the top of the frame 21. The belt conveying assembly is arranged on the top of the frame 21, and the lifting conveying assembly is arranged inside the frame 21. The maximum conveying height that the lifting conveying assembly can reach for the product is equal to the conveying height of the second roller conveyor 3 for the product. The flipping mechanism is arranged on the second roller conveyor 3.
[0022] As Figure 2 shown, the belt conveying assembly includes a first motor 221, a first roller 222 and a first belt assembly 223. The first rollers 222 are rotatably connected to both the left and right sides of the top of the frame 21. The first motor 221 is installed on the upper part of the front side of the frame 21. The output shaft of the first motor 221 is fixedly connected to the left first roller 222. The first belt assembly 223 is composed of two belt pulleys and a flat belt. The two belt pulleys are respectively fixedly connected to the two first rollers 222, and the flat belt is wound around the outer circumferences of the two belt pulleys. There are five first belt assemblies 223, and they are evenly spaced on the two first rollers 222.
[0023] It should be noted that when the left first roller 222 is driven to rotate by the first motor 221, the left first roller 222 can drive the right first roller 222 to rotate through the first belt assembly 223. During this process, the flat belt of the first belt assembly 223 will continuously rotate, so as to convey the product placed on the belt conveying assembly.
[0024] As Figure 3 and Figure 4As shown, the lifting and conveying assembly includes a cylinder 231, a lifting plate 232, a mounting frame 233, a roller 234, a belt assembly 235, a rotating shaft 236, a rotating shaft 237, a bevel gear 1 238, a bevel gear 239 and a motor 2310. The lifting plate 232 is slidably connected to the upper part of the frame 21, and the cylinder 231 is installed in the lower part of the frame 21. The telescopic rod of the cylinder 231 faces upward and is fixed to the bottom of the lifting plate 232. Two mounting frames 233 are fixedly connected to the top of the lifting plate 232 symmetrically. Five rollers 234 are rotatably connected to the tops of the two mounting frames 233. The rollers 234 and the belt assembly 1 223 are arranged at intervals. The lower part of the mounting frame 233 on the right side is rotatably connected with five rotating shafts 236 corresponding to the positions of rollers 234 one by one, and the rotating shafts 236 are all connected to the corresponding rollers 234 through belt assemblies 235. The top right side of the lifting plate 232 is rotatably connected with a rotating shaft 237, and the left end of the rotating shaft 236 is fixedly connected with a bevel gear 1 238. Five bevel gears 239 corresponding to the positions of the rotating shaft 236 are fixedly connected to the rotating shaft 237, and the bevel gears 239 are meshed with the corresponding bevel gears 238. A motor 2310 is installed on the top of the lifting plate 232, and the output shaft of the motor 2310 is fixedly connected to the rotating shaft 237.
[0025] It should be noted that: by driving the extension and contraction of the telescopic rod through the cylinder 231, the lifting plate 232 and the components thereon can be moved upward or downward. When the rotating shaft 237 is driven to rotate by the motor 2310, the rotating shaft 237 will drive the rotating shaft 1 236 to rotate through the meshing action of the bevel gear 239 and the bevel gear 1 238, so that the rotating shaft 1 236 drives the roller 2 234 to rotate through the belt assembly 235, and then the products placed on the roller 234 can be transported.
[0026] like Figure 5As shown in the figure, the flipping mechanism includes a support frame 401, a rotating plate 402, a motor three 403, a motor four 404, a bidirectional lead screw 405, a guide rod 406 and a clamping rod 407. Two support frames 401 are fixedly connected to the left and right sides of the roller conveyor two 3 respectively. On one side of the two support frames 401 close to each other, rotating plates 402 are rotatably connected. The rotation axes of the two rotating plates 402 are on the same straight line, and the distance between the rotation axes of the two rotating plates 402 and the roller conveyor two 3 is greater than the length of the product. On one side of the two rotating plates 402 close to each other, a bidirectional lead screw 405 and a guide rod 406 are respectively provided. The bidirectional lead screw 405 is rotatably connected to the rotating plate 402, and the guide rod 406 is fixedly connected to the rotating plate 402. A motor three 403 is installed on the right rotating plate 402, and the output shaft of the motor three 403 is fixedly connected to the bidirectional lead screw 405. A motor four 404 is installed on the right support frame 401, and the output shaft of the motor four 404 is fixedly connected to the rotating plate 402. Two clamping rods 407 are symmetrically connected up and down between the bidirectional lead screw 405 and the guide rod 406. The clamping rods 407 are all threadedly connected to the bidirectional lead screw 405 and are all slidably connected to the guide rod 406.
[0027] It should be noted that: by driving the forward and reverse rotation of the bidirectional lead screw 405 through the motor three 403, the two clamping rods 407 can move closer to or away from each other along the bidirectional lead screw 405 under the guidance of the guide rod 406, so as to clamp or release the product. When the motor four 404 drives the right rotating plate 402 to rotate, the left rotating plate 402 can be driven to rotate synchronously through the clamping rod 407, so as to flip the product clamped by the two clamping rods 407.
[0028] Working principle: When in use, the product is conveyed to the belt conveying assembly by the roller conveyor 1 on the left. When the product passes by the CCD camera 5, the CCD camera 5 will identify the front and back of the product. When the CCD camera 5 identifies that the product is in the correct orientation, the product is directly conveyed to the roller conveyor 1 on the right through the belt conveying assembly. When the CCD camera 5 identifies that the product is in the reverse orientation, the lifting plate 232 is driven to move upward by the cylinder 231, so that the roller 234 drives the reverse-oriented product to move upward until it reaches the same conveying height as the roller conveyor 2 3. Then, the rotating shaft 1 236 is driven to rotate by the motor 2 2310, the bevel gear 1 238 and the bevel gear 2 239. At the same time, the rotating shaft 1 236 drives the roller 234 to rotate through the belt assembly 2 235, so as to convey the reverse-oriented product to the roller conveyor 2 3; when the reverse-oriented product comes between the two clamping rods 407 during the conveying by the roller conveyor 2 3, the bidirectional lead screw 405 is driven to rotate by the motor 3 403, so that the two clamping rods 407 move towards each other on one side under the guidance of the guide rod 406 until the two clamping rods 407 clamp and limit the reverse-oriented product. Then, the rotating plate 402 is driven to rotate 180 degrees by the motor 4 404, so that the two clamping rods 407 and the reverse-oriented product they hold are flipped 180 degrees, turning the reverse-oriented product into the correct orientation. Subsequently, the bidirectional lead screw 405 is driven to rotate in the reverse direction by the motor 3 403, so that the two clamping rods 407 move away from each other on one side under the guidance of the guide rod 406 until the flipped product is reset to the roller conveyor 2 3 again, and then it is continuously conveyed by the roller conveyor 2 3.
[0029] As Figure 1 shown, it further includes an electric slide rail 601, an electric slide seat 602 and a baffle 603. Two electric slide rails 601 are symmetrically arranged front and back on the right side of the top of the frame 21. Electric slide seats 602 are slidably connected to the side of the two electric slide rails 601 close to each other, and a baffle 603 is fixedly connected between the two electric slide seats 602.
[0030] It should be noted that: when the CCD camera 5 identifies that the product is in the reverse orientation, the baffle 603 is driven to move downward through the electric slide rail 601 and the electric slide seat 602 until the bottom of the baffle 603 is close to the flat belt of the belt assembly 1 223 to block the reverse-oriented product. When the CCD camera 5 identifies that the product is in the correct orientation, the baffle 603 is driven to move upward and reset through the electric slide rail 601 and the electric slide seat 602 so as not to block the passage of the product in the correct orientation.
[0031] Those skilled in the art of this industry should understand that the above embodiments do not limit the present utility model in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present utility model.
