Description

Technical Field

[0001] This invention relates to the field of sorting equipment, and more particularly to an mSAP high-speed barcode reading and sorting machine. Background Technology

[0002] In modern logistics, electronics manufacturing, pharmaceutical and food packaging industries, rapid and accurate barcode reading, inspection, and sorting of PCB boards are crucial for ensuring production efficiency and product quality. Traditional barcode reading and sorting operations often rely on manual labor or semi-automatic equipment, which suffers from low efficiency, high error rates, and difficulty in meeting the cycle time requirements of high-speed production lines.

[0003] Especially when it is necessary to read and inspect both sides of a product, existing equipment is often complex in structure and has poor workstation connections, resulting in limited overall processing speed. Therefore, developing a highly integrated, fast-processing mSAP high-speed barcode reading and sorting machine with automatic cleaning and multi-sided barcode reading functions has significant market value. Summary of the Invention

[0004] The purpose of this invention is to provide an mSAP high-speed barcode reading and sorting machine that solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an mSAP high-speed barcode reading and sorting machine, comprising a frame, a conveyor line arranged within the frame, and a rotary lifting material handling assembly, a front barcode reading and handling assembly, a cleaning assembly, a front detection camera, and a material unloading and handling assembly sequentially arranged along the conveyor line on the frame. An automatic feeding bin, a back barcode reading assembly, and a back detection camera are arranged on the frame next to the rotary lifting material handling assembly. The rotary lifting material handling assembly includes an electric cylinder, a hollow rotary platform, a turntable, a slip ring, and a first vacuum suction cup. The electric cylinder is fixedly connected to the frame, and the hollow rotary platform is connected to the electric cylinder... The piston rod is fixedly connected, the turntable is fixedly connected to the rotating end of the hollow rotating platform, the fixed end of the air slip ring is slidably connected to the frame, the rotating end of the air slip ring is fixedly connected to the turntable, the first vacuum suction cup is fixedly connected to the turntable, the conveyor line includes a roller line and a conveyor belt, both of which are fixedly connected to the frame, the cleaning components are located at the roller line, there are two cleaning components, which are respectively arranged on the upper and lower sides of the roller line, and there are multiple unloading and handling components, with an automatic storage bin fixedly connected to the frame next to each unloading and handling component.

[0006] Furthermore, the front-facing barcode reader and transport assembly includes a first XY moving module fixedly connected to the frame, a front-facing barcode reader camera fixed to the moving end of the first XY moving module, and a second vacuum suction cup.

[0007] Furthermore, the cleaning assembly includes a dust hood and a fume filter fixedly connected to the frame, and an ion fan fixedly connected inside the dust hood.

[0008] Furthermore, the unloading and handling assembly includes an unloading robot fixed on the frame and a third vacuum suction cup fixedly connected to the moving end of the unloading robot.

[0009] Furthermore, the rear barcode reader assembly includes a second XY moving module fixedly connected to the frame and a rear barcode reader camera fixedly connected to the moving end of the second XY moving module.

[0010] Furthermore, a stacking plate detection assembly is provided on the frame at the gap between the rollers of the roller line. The stacking plate detection assembly includes an upper displacement sensor and a lower displacement sensor. The upper displacement sensor and the lower displacement sensor are both fixedly connected to the frame and are located on the upper and lower sides of the roller line, respectively.

[0011] Furthermore, an NG platform is fixedly connected to the frame next to the conveyor line.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] By organically integrating multiple functional modules such as automatic feeding, back barcode reading detection, front material handling, front barcode reading detection, automatic cleaning, and unloading sorting along the conveyor line, a compact and efficient production line is formed, reducing material handling time and significantly improving overall sorting efficiency.

[0014] The rotary lifting and material handling assembly uses a combination of an electric cylinder, a hollow rotary platform, and an air slip ring to achieve a composite motion of material handling, lifting, and rotation. The air slip ring design ensures a stable air supply to the first vacuum suction cup during continuous rotation, avoiding pipe entanglement and ensuring smooth and reliable operation.

[0015] Equipped with a cleaning component, the product can be conveyed to the cleaning component for dust removal or static electricity removal;

[0016] By installing a stacking detection component at the gap in the roller conveyor, it is possible to accurately detect whether products are overlapping. Attached Figure Description

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Example:

[0028] like Figures 1-7The mSAP high-speed barcode reading and sorting machine shown includes a frame with a conveyor line 1 for transporting products inside. Along the conveying direction of the conveyor line 1, a rotary lifting and picking assembly 2, a front barcode reading and handling assembly 3, a cleaning assembly 4, a front inspection camera 9, and a unloading and handling assembly 5 are sequentially fixedly mounted on the frame. Simultaneously, located beside the rotary lifting and picking assembly 2 on the frame, an automatic feeding bin 6, a back barcode reading assembly 7, and a back inspection camera 8 are also provided. The automatic feeding bin 6 is used to store products (PCB boards) to be sorted, the back barcode reading assembly 7 is used to read the barcodes or QR codes on the back of the products, and the back inspection camera 8 is used to detect whether there are any defects on the appearance of the back of the products.

[0029] The rotary lifting and material handling assembly 2 specifically includes an electric cylinder 201, a hollow rotary platform 202, a turntable 203, an air slip ring 204, and a first vacuum suction cup 205. The housing of the electric cylinder 201 is fixedly connected to the frame, and its piston rod can extend and retract vertically. The fixed end of the hollow rotary platform 202 (e.g., the housing) is fixedly connected to the end of the piston rod of the electric cylinder 201, allowing the hollow rotary platform 202 to rise and fall with the electric cylinder 201. The turntable 203 is fixed to the rotating end of the hollow rotary platform 202 and is driven to rotate by the hollow rotary platform 202. The fixed end of the air slip ring 204 is slidably connected to the frame (e.g., through a linear guide pair), allowing it to move vertically; the rotating end of the air slip ring 204 is fixedly connected to the center of the turntable 203. Multiple first vacuum suction cups 205 are evenly distributed and fixed around the turntable 203. An external vacuum source is connected to the fixed end inlet of the air slip ring 204 via a pipeline, and then connected to the first vacuum suction cup 205 via a pipeline from the rotating end outlet of the air slip ring 204. During operation, the electric cylinder 201 drives the first vacuum suction cup 205 to descend and pick up the product from the automatic feeding bin 6, and then rises. Each time, the hollow rotating platform 202 drives the turntable 203 to rotate a certain angle (e.g., 90 degrees), sequentially transferring the product from the picking station to the back barcode reading station, the back visual inspection station, and the preliminary unloading station, directly placing it onto the conveyor line 1. The air slip ring 204 ensures that the air path remains connected throughout the rotation process.

[0030] The conveyor line 1 includes a segmented roller conveyor 101 and a conveyor belt 102. Both the roller conveyor 101 and the conveyor belt 102 are fixedly connected to the frame. Two cleaning components 4 are located at the roller conveyor 101, one above the other, cleaning the product from both sides. Each cleaning component 4 includes a dust hood 401, a fume filter 402, and an ionizer 403. The dust hood 401 is fixedly connected to the frame and faces the conveying plane of the roller conveyor 101, forming a localized cleaning area. The fume filter 402's inlet communicates with the interior of the dust hood 401, used to suck up and filter dust or fumes generated during cleaning. The ionizer 403 is fixedly installed inside the dust hood 401, with its outlet facing the conveyed product, used to blow out ionized air to remove static electricity and adhering fine dust from the product surface. When the product needs cleaning, it slowly passes between the upper and lower cleaning components 4 on the roller line 101, receiving ion air blowing from both above and below, achieving efficient cleaning on both sides.

[0031] The front-side barcode reading and handling assembly 3 includes a first XY moving module 301, a front-side barcode reading camera 302, and a second vacuum suction cup 303. The fixed end of the first XY moving module 301 is fixedly connected to the frame, and its moving end can move in the X and Y axes of the horizontal plane. The front-side barcode reading camera 302 and the second vacuum suction cup 303 are both fixedly mounted on the moving end of the first XY moving module 301. The function of this assembly is to read the barcode on the front of the product above the conveyor belt 102. If an error occurs in the front or back barcode reading, the first XY moving module 301 drives the second vacuum suction cup 303 to pick up and transfer the product to the NG platform 12. Products with correct barcode readings will continue to be transported to the cleaning station via the conveyor belt 102.

[0032] Multiple unloading and handling components 5 are specifically configured. Each unloading and handling component 5 includes an unloading robot 501 fixed on the frame and a third vacuum suction cup 502 fixed at its moving end. The unloading robot 501 can be an articulated robot or an XYZ three-axis modular robot. On the frame, an automatic storage bin 13 is fixedly connected to the side of each unloading and handling component 5. These automatic storage bins 13 can be used to store products of different categories or with different inspection results. For example, one automatic storage bin 13 is used to store Class A qualified products, and another is used to store Class B qualified products. Based on the comprehensive inspection results of the front barcode reader 302, the back barcode reader 702, the front inspection camera 9, and the back inspection camera 8, the system controls the corresponding unloading robot 501 to drive the third vacuum suction cup 502 to pick up the product and place it into the corresponding automatic storage bin 13, thereby achieving refined sorting.

[0033] The back-side barcode reader assembly 7 includes a second XY moving module 701 and a back-side barcode reader camera 702. The second XY moving module 701 is fixed on the frame, and the back-side barcode reader camera 702 is fixed to the moving end of the second XY moving module 701. When the rotating lifting and picking assembly 2 picks up the product and lifts it to a certain height, the second XY moving module 701 drives the back-side barcode reader camera 702 to move and scan the barcode on the back of the product.

[0034] Please see Figure 4 To prevent products from stacking (e.g., two products sticking together) and entering subsequent workstations, this embodiment includes a stacking detection assembly located on the frame at the gap between the rollers of the roller conveyor 101. This assembly includes an upper displacement sensor 10 and a lower displacement sensor 11, both fixedly connected to the frame and located on the upper and lower sides of the conveying plane of the roller conveyor 101, respectively. When a single product passes through, the distance measured by the upper and lower sensors is approximately equal to the product's thickness. When two or more products pass through stacked, the distance measured by the upper displacement sensor 10 will significantly decrease, or the lower displacement sensor 11 will detect the product below earlier. The controller determines whether stacking has occurred based on the difference in sensor signals.

[0035] In addition, to facilitate the handling of products with incorrect code reading information discovered during the code reading process, an NG platform 12 is fixedly connected to the rack next to the conveyor line 1 (for example, near the unloading and handling assembly 5). The unloading and handling assembly 5 can temporarily store products with incorrect code reading information on the NG platform 12.

[0036] The typical workflow of the mSAP high-speed barcode reader and sorter according to an embodiment of the present invention is as follows:

[0037] The rotating lifting material handling component 2 picks up the product from the automatic feeding bin 6, rises and rotates and sequentially conveys it to the back barcode reading station, the back visual inspection station and the preliminary unloading station.

[0038] The product undergoes code reading and appearance inspection at the back-side code reading station and the back-side visual inspection station, respectively, by the back-side code reading component 7 and the back-side inspection camera 8. If there are abnormal dents, protrusions or cracks during the back-side appearance inspection, the product is a defective product; otherwise, it is a qualified product.

[0039] At the initial unloading station, the rotary lifting and picking component 2 transfers the product to the conveyor belt 102.

[0040] The product is conveyed by roller conveyor 101 to the front barcode reading and handling component 3. The front of the product is read above the conveyor belt 102. If the front barcode reading information is incorrect or the back barcode reading information is incorrect, the first XY moving module 301 drives the second vacuum suction cup 303 to pick up and transfer the product to the NG platform 12. The product with the correct barcode reading will continue to be conveyed to the cleaning station via the conveyor belt 102.

[0041] If the product is conveyed to the roller line 101 and then enters between the upper and lower cleaning components 4, the upper and lower ion fans 403 will clean both sides of the product simultaneously.

[0042] After cleaning, the product is inspected by a front-facing inspection camera. The front of the product is visually inspected, and if there are any abnormal dents, bulges or cracks, it is a defective product; otherwise, it is a qualified product.

[0043] Finally, based on the comprehensive logical judgment of all code reading and detection results, the system selects the corresponding unloading and handling component 5. According to the product qualification status and the reason for the defect (such as front appearance defects, back appearance defects or double-sided appearance defects, etc.), the component picks up the product and classifies it into the corresponding automatic storage bin 13 to achieve classified storage.

[0044] In this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as falling within the protection scope of the present invention.
