Description

Technical Field

[0001] This utility model relates to the field of item sorting equipment technology, and in particular to an item sorting device based on machine vision. Background Technology

[0002] Image recognition technology is an important field of artificial intelligence. It refers to the technology of object recognition in images to identify targets and objects of various patterns. When applied in the field of industrial production, it can provide machine vision, thereby facilitating the identification and sorting of industrial products.

[0003] In the existing technology, sorting devices using image recognition technology can perform batch inspection and classification of products. Compared with manual inspection by visual observation, it is more efficient and has less error. It is an indispensable step in realizing the automation of product production. However, the existing sorting devices have low adjustability and cannot adapt their sorting parts to products of different sizes, leaving room for improvement. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing sorting devices have low adjustability and cannot adapt their sorting sections to products of different sizes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a machine vision-based item sorting device, comprising: a base, characterized in that: a motor is disposed inside the base, the output shaft of the motor is drivenly connected to a conveyor rail, two track grooves are formed on the outer surface of the conveyor rail, multiple pulleys are slidably connected inside the two track grooves, fixed blocks are movably connected to both sides of the multiple pulleys, linkage blocks are fixedly connected to the other side of the multiple fixed blocks, and sorting components are disposed on one side of the multiple linkage blocks.

[0006] The technical effect of adopting the above-mentioned further solution is that the output shaft of motor one drives the transmission rail to rotate, the rotation of the transmission rail causes the track groove to rotate synchronously, and the pulley can slide inside the track groove to adjust the position of the linkage block.

[0007] In a preferred embodiment, the sorting assembly includes multiple support trays, each support tray having a buffer spring fixedly connected to one side, and each buffer spring having a support column fixedly connected to the other side. Each support column is fixedly connected to the top of a movable block. Each support tray has a slider slidably connected to its bottom, and each slider has a connecting shaft fixedly connected to its bottom. Each connecting shaft has a movable block fixedly connected to its other side. Each movable block has a movable groove on one side, and each movable block is slidably connected inside the movable groove. Each movable block has a connecting rod fixedly connected to its bottom. Multiple support frames are fixedly connected to the top of the base, and each support frame has a signal receiver on its top. Each support frame has an electric push rod at its bottom, and an adjustment assembly is provided on one side of the base.

[0008] The technical effect of adopting the above-mentioned further solution is as follows: After the machine vision body receives the input information, it transmits it to the inside of the signal receiver. After receiving the signal from the signal receiver, the electric push rod is activated. The electric push rod squeezes the connecting rod. After the connecting rod is squeezed, it drives the movable block to move inside the movable groove. The movement of the movable block drives the slider to move at the bottom of the support plate through the connecting shaft. After the support plate is supported by the connecting shaft, the object on the support plate falls into the inside of the support bar at an angle. When the support plate becomes an angled surface, after the squeezing force of the electric push rod disappears, the rebound effect of the buffer spring drives the support plate back to a flat state.

[0009] In a preferred embodiment, the adjustment assembly includes a cylindrical frame, which is fixedly connected to one side of the base. A second motor is fixedly connected to the top of the cylindrical frame. A threaded rod is fixedly connected to the output shaft of the second motor. A threaded sleeve is movably connected to the outer surface of the threaded rod. A support plate is fixedly connected to one side of the threaded sleeve. A machine vision body is fixedly connected to the top of the support plate. A collection assembly is provided on one side of the base.

[0010] The technical effect of adopting the above-mentioned further solution is that the output shaft of motor two drives the threaded rod to rotate, the rotation of the threaded rod causes the threaded sleeve to drive on the outer surface of the threaded rod, and the movement of the threaded sleeve drives the machine vision body to scan and capture the object through the support plate, thereby adjusting the height of the machine vision body.

[0011] In a preferred embodiment, the collection assembly includes multiple support bars, which are fixedly connected to one side of the base. Each of the multiple support bars is fixedly connected to an inclined rail. Each inclined rail is fixedly mounted with a baffle at its top. Each inclined rail is fixedly connected with two buffer springs, and each buffer spring is fixedly connected to a buffer plate at its other side. Multiple collection boxes are arranged around the base.

[0012] The technical effect of adopting the above-mentioned further solution is as follows: the support bar is used to support the ramp. When the item falls into the interior of the ramp, the item falls onto the buffer plate and squeezes the second buffer spring. The second buffer spring cushions the item on the buffer plate. When the baffle is supported and the ramp is formed, the item does not fall into the interior of the ramp, thus blocking the item.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the machine vision body scans and captures an object, places the object inside the support plate, and transmits the information received by the machine vision body to the signal receiver. Upon receiving the signal from the signal receiver, the machine vision body activates the electric push rod, which presses against the connecting rod. The pressing of the connecting rod causes the movable block to move inside the movable groove. The movement of the movable block, through the connecting shaft, causes the slider to move at the bottom of the support plate. After the support plate is no longer supported by the connecting shaft, the object on the support plate falls at an angle into the inside of the inclined path. Attached Figure Description

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, such as Figure 1-6As shown, it includes: a base 1, characterized in that: a motor 101 is disposed inside the base 1, the output shaft of the motor 101 is driven to a conveyor rail 102, two track grooves 103 are formed on the outer surface of the conveyor rail 102, multiple pulleys 104 are slidably connected inside the two track grooves 103, fixed blocks 105 are movably connected to both sides of the multiple pulleys 104, linkage blocks 106 are fixedly connected to the other side of the multiple fixed blocks 105, a sorting component is disposed on one side of the multiple linkage blocks 106, the sorting component includes multiple support plates 110, buffer springs 109 are fixedly connected to one side of the multiple support plates 110, and support columns 108 are fixedly connected to the other side of the multiple buffer springs 109. All 108 are fixedly connected to the top of the movable block 107. The bottom of the multiple support plates 110 are slidably connected to sliders 111. The bottom of the multiple sliders 111 is fixedly connected to connecting shafts 112. The other side of the multiple connecting shafts 112 is fixedly connected to the movable block 107. One side of the multiple linkage blocks 106 is provided with a movable groove 113. The multiple movable blocks 107 are slidably connected inside the multiple movable grooves 113. The bottom of the multiple movable blocks 107 is fixedly connected to connecting rods 114. The top of the base 1 is fixedly connected to multiple support frames 115. The top of the multiple support frames 115 is provided with signal receivers 116. The bottom of the multiple support frames 115 is provided with electric push rods 117. An adjustment component is provided on one side of the base 1.

[0026] In this embodiment, the output shaft of motor 101 drives the transmission rail 102 to rotate. The rotation of the transmission rail 102 causes the track groove 103 to rotate synchronously. The pulley 104 can slide inside the track groove 103 to adjust the position of the linkage block 106. After receiving the input information, the machine vision body 205 transmits it to the inside of the signal receiver 116. After receiving the signal from the signal receiver 116, the electric push rod 117 is activated. The electric push rod 117 squeezes the connecting rod 114. After the connecting rod 114 is squeezed, it drives the movable block 107 to move inside the movable groove 113. The movement of the movable block 107 drives the slider 111 to move at the bottom of the support plate 110 through the connecting shaft 112. After the support plate 110 is supported by the connecting shaft 112, the item on the support plate 110 falls at an angle into the inside of the support bar 301. When the support plate 110 becomes an angled surface, after the squeezing force of the electric push rod 117 disappears, the rebound effect of the buffer spring 109 drives the support plate 110 back to a flat state.

[0027] Example 2, as Figure 1-6As shown, the adjustment assembly includes a cylindrical frame 2, which is fixedly connected to one side of the base 1. A second motor 201 is fixedly connected to the top of the cylindrical frame 2. A threaded rod 202 is fixedly connected to the output shaft of the second motor 201. A threaded sleeve 203 is movably connected to the outer surface of the threaded rod 202. A support plate 204 is fixedly connected to one side of the threaded sleeve 203. A machine vision body 205 is fixedly connected to the top of the support plate 204. A collection assembly is provided on one side of the base 1.

[0028] In this embodiment, the output shaft of motor 201 drives the threaded rod 202 to rotate. The rotation of the threaded rod 202 causes the threaded sleeve 203 to be driven on the outer surface of the threaded rod 202. The movement of the threaded sleeve 203 drives the machine vision body 205 to scan and capture the object through the support plate 204, thereby adjusting the height of the machine vision body 205.

[0029] Working Principle: This equipment is a machine vision-based item sorting device. During use, motor 201 is started, and its output shaft drives threaded rod 202 to rotate. The rotation of threaded rod 202 causes threaded sleeve 203 to move on its outer surface. The movement of threaded sleeve 203, via support plate 204, drives machine vision unit 205 to scan and capture items, thereby adjusting the height of machine vision unit 205. Items are placed inside support plate 110. After receiving the input information, machine vision unit 205 transmits it to signal receiver 116. Upon receiving the signal from signal receiver 116, electric push rod 117 is activated. Electric push rod 117 connects to... The rod 114 is squeezed, and after the connecting rod 114 is squeezed, it drives the movable block 107 to move inside the movable groove 113. The movable block 107 moves through the connecting shaft 112 to drive the slider 111 to move at the bottom of the support plate 110. After the support plate 110 is supported by the connecting shaft 112, the items on the support plate 110 fall at an angle into the inside of the inclined chute 3. The items fall onto the buffer plate 303 for buffering and then fall into the collection box 305 for collection. At this time, the collection box 305 can also be replaced by a conveyor belt to enhance the transmission effect and solve the problem that the sorting device has low adjustability and cannot adapt to the sorting part according to the different sizes of products.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
