DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Reference Figure 1-12 , an automatic material distribution and transfer device for thin semi-finished products, comprising a feeding chain 3, the feeding chain 3 is formed by a plurality of chain links 23 connected in sequence, and a transport carrier 22 is pinned on the chain link 23 for transporting wooden dining forks, such as Figure 6 As shown, the input end of the feeding chain 3 is provided with a feeding detection mechanism, and the output end is provided with a material dividing and transferring mechanism;

[0032] The feeding detection mechanism comprises a feeding bin 1, an industrial linear array camera 5 and a material removal box 7 which are arranged in sequence, and a pneumatic material removal valve 6 which cooperates with the material removal box 7 is provided at the lower side of the material removal box 7;

[0033] Specifically, the model of the industrial line array camera 5 is a Basler acA1600-20gm GigE camera, equipped with a SonyICX274 CCD photosensitive chip, 20 frames per second, and a resolution of 2 million pixels; a grayscale-based template matching method is used for target recognition, and classification is performed according to the material posture.

[0034] The specific process of feeding detection and rejection is as follows:

[0035] Template creation: Select complete and defect-free materials for template making, take photos of the materials in different postures, create a grayscale template, and obtain a grayscale outline.

[0036] Template matching: The materials on the assembly line trigger the infrared photoelectric switch. After receiving the signal, the camera takes a picture of the material and matches the obtained photo with the template to determine which category the material should be classified into.

[0037] Pneumatic rejection: The material on the assembly line triggers the photoelectric switch, and the camera receives the signal to take a photo of the material, and performs defect detection on the acquired photo. If there is a defect, the pneumatic rejection valve 6 is triggered to reject the defective material.

[0038] like Figure 3 As shown, the bottom of the pneumatic ejection valve 6 is an air inlet pipe. When the industrial linear array camera 5 gives a rejection signal, it is activated and the valve is opened. At this time, due to the different lengths of the left and right branch pipes, the pneumatic force is generated on the left before the right, and the air is blown onto the wooden catering fork on the feeding chain 3, and then blown into the ejection box 7.

[0039] A slot 13 is provided at the outlet of the loading bin 1 , and a brush 2 is rotatably connected just above the slot 13 . The brush 2 can brush off excess material to ensure that there is only one material on each chain link 23 .

[0040] The industrial linear array camera 5 is provided with a camera support frame 4 , which is in a "X" shape. The upper end of the camera support frame 4 is provided with a shooting port 14 corresponding to the industrial linear array camera 5 .

[0041] The material distribution and transfer mechanism includes a plurality of transfer silos 12 arranged on the upper side of the feeding chain 3, and each of the transfer silos 12 is arranged in sequence along the feeding chain 3. A left and a right group of lifting wheels 10 are arranged on the lower side of each group of the transfer silos 12. Horizontal positioning plates 8 are also provided on both sides of the feeding chain 3, and the horizontal fixing plates 8 are fixedly connected to the transfer silos 12.

[0042] like Figure 8As shown, a stepper motor support frame 11 is provided on the lower side of the transfer silo 12, and a plurality of stepper motor fixing frames 21 are provided on the stepper motor support frame 11. A plurality of stepper motors 9 are distributed in an array on the stepper motor support frame 11, and each stepper motor 9 is respectively mounted on each stepper motor fixing frame 21, and each of the material lifting wheels 10 is respectively mounted on each stepper motor 9, and a material lifting wheel mounting port 20 corresponding to the material lifting wheel 10 is provided on the stepper motor support frame 11.

[0043] The wooden dining fork has two postures on the conveyor chain: the large end facing left and the large end facing right.

[0044] When the material arrives at the corresponding transfer silo 12, the stepper motor 9 drives the corresponding lifting wheel 10 to rotate 30 degrees, and the lifting teeth 18 on the lifting wheel 10 squeeze the material into the corresponding transfer silo 12. When the next material arrives, it rotates another 30 degrees to continue squeezing the material into the transfer silo 12.

[0045] The material posture is classified by taking pictures and identifying with the industrial linear array camera 5, and different postures correspond to different transfer bins 12. When a certain material passes through the camera, the infrared photoelectric switch is triggered to take a picture to determine which posture it belongs to, determine the corresponding transfer bin 12, and thus determine how many chain links 23 need to be moved, and count through the pulse wheel. Every time the pulse wheel rotates one tooth, the feeding chain 3 moves one chain link 23 (that is, the total number of chain links required to move - 1). When it moves to the corresponding transfer bin 12 (that is, the total number of chain links required to move = 0), a pulse signal is given to the stepper motor 9, and the stepper motor 9 drives the lifting wheel 10 to rotate 30 degrees.

[0046] Reference Figure 9-12 The material lifting wheel 10 is composed of a rotating column 15 and multiple groups of material lifting pieces 16 fixed on the side wall of the rotating column 15. The material lifting pieces 16 are divided into two groups and are staggered. The material lifting pieces 16 are composed of a fixed shaft 17, a material lifting tooth 18 and a return spring 19. The fixed shaft 17 is fixedly connected to the side wall of the rotating column 15. The material lifting tooth 18 is rotatably connected to the fixed shaft 17. The return spring 19 is fixedly connected between the rotating column 15 and the material lifting tooth 18. The return spring 19 is fixedly connected to the rear part of the material lifting tooth 18.

[0047] The operating principle of the present invention is now described as follows:

[0048] When the present invention is used, the industrial linear array camera 5 is used to detect the materials on the feeding chain 3 to detect whether the materials are qualified and determine the posture of the materials, thereby providing the necessary classification basis for subsequent classification. The stepper motor 9 drives the lifting wheel 10 to classify materials with different postures. The rotation of the lifting wheel 10 squeezes different types of materials into a pre-designed transfer silo 12. Different transfer silos 12 are respectively used to place materials with different postures, thereby achieving the purpose of automatically classifying the materials. The other end of the transfer silo 12 is connected to other conveyor lines, so that the sorted and classified materials are directly transferred from the sorting and classification conveyor line to the conveyor lines of other stations, thereby achieving automatic transfer of different conveyor lines, reducing the labor intensity of workers, and also reducing the production cost of using a robotic arm for handling.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
