Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to an automatic barcode scanning mechanism based on the Internet of Things. Background Technology

[0002] Scanning barcodes is a basic operation in the online production process and is performed in multiple locations. Currently, online scanning is done manually using barcode scanners.

[0003] The applicant has discovered that the existing technology has at least the following technical problems: manual scanning is time-consuming and labor-intensive, has high labor costs, and is prone to fatigue, which can lead to missed scans. The scans are only discovered when they are linked to the system data in the subsequent process, requiring the personnel in that position to go to the next process to scan again, causing the production line to stop and reducing output. Utility Model Content

[0004] The purpose of this invention is to provide an automatic barcode scanning mechanism based on the Internet of Things to solve the technical problems of manual barcode scanning in the prior art, which is time-consuming, labor-intensive, costly, and prone to missed scans.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The present invention provides an automatic barcode scanning mechanism, including a sorting mechanism installed on both sides of the production line for aligning the conveyed products, barcode scanners and incoming material counting mechanisms arranged on the left and right sides of the sorting mechanism.

[0006] The automatic barcode scanning mechanism of this utility model automatically aligns the conveyed products by setting up sorting mechanisms on both sides of the production line, and completes product barcode scanning in conjunction with the barcode scanner. It also uses an incoming material counting mechanism to automatically count incoming materials, realizing synchronous linkage between barcode scanning and counting, and achieving automatic barcode scanning and product counting at the same time.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] As a further improvement of this utility model, it also includes a PLC control module, and the incoming material counting mechanism and the barcode scanner are both electrically connected to the PLC control module.

[0009] This invention utilizes a PLC control module to centrally control the incoming material counting mechanism and the barcode scanner. The data scanned by the barcode scanner is sent to the PLC control module, and the incoming material counting mechanism transmits the product arrival signal to the PLC control module. The PLC control module performs counting and can determine whether there are missed or repeated scans based on the logical comparison between the incoming material counting signal and the scanning result. When there is a discrepancy between the two data, it is determined to be a scanning abnormality, and the production line is stopped in time to prevent missed or repeated scans from entering the subsequent process, thus realizing an automatic barcode scanning and anti-missing function.

[0010] As a further improvement of this utility model, the sorting mechanism includes a guiding component and a pushing component; the guiding component is disposed on one side of the production line body, and the pushing component is disposed opposite to the guiding component on the other side of the production line body.

[0011] The sorting mechanism of this utility model includes a guide component and a pusher component arranged opposite to each other. The guide component is used to guide and sort the incoming material on one side, while the pusher component is located on the opposite side of the guide component and is used to push and sort the incoming material on the other side. This enables automatic centering and posture correction of the product during the conveying process, ensuring that the product enters the scanning area in a uniform orientation and improving the success rate of barcode scanner recognition.

[0012] As a further improvement of this utility model, the guiding assembly includes a lower support frame, a connecting rod, and a guiding rod; wherein: The lower support frame is fixed to the side of the production line body; The connecting rod passes through the sleeve at the top of the lower support frame; The guide rod is installed at the end of the connecting rod.

[0013] The guiding component of this utility model is fixed by a lower support frame, and the guiding rod is connected to the sleeve at the top of the lower support frame through a connecting rod. It has a simple structure and low cost.

[0014] As a further improvement of this utility model, the guide rod has an arc-shaped first guide portion on the side facing the incoming material.

[0015] By incorporating a first guide section, the incoming material can be centered and properly aligned, preventing damage from impacts and improving the surface quality protection of the product. The first guide section features a rounded transition structure, ensuring smooth guidance upon contact with the material, reducing frictional resistance, and guaranteeing stable and efficient processing.

[0016] As a further improvement of this utility model, the connecting rod is movably inserted into the sleeve and can move back and forth relative to the sleeve. It also includes a locking member, which is disposed between the connecting rod and the sleeve.

[0017] This utility model, by setting a connecting rod that can move back and forth and cooperating with a locking component, realizes flexible adjustment and quick fixation of the guide rod position, adapts to the centering needs of products of different specifications, and improves the versatility and ease of adjustment of the equipment.

[0019] The feeding assembly of this invention uses pneumatic drive combined with a sensor to sense the material's position and trigger the feeding action in real time, thus avoiding interference with the operation of the conveyor line.

[0020] As a further improvement of this utility model, the pusher plate has an arc-shaped second guide portion on the side facing the incoming material.

[0021] By incorporating a second guide section, the posture of the incoming material is further adjusted. The second guide section works in conjunction with the first guide section to form a bidirectional guiding structure, ensuring smooth alignment of the incoming material during the pushing process and preventing skewing or jamming. The pusher plate, driven by a telescopic cylinder, precisely pushes the side of the product, and combined with sensor feedback, achieves closed-loop position control, further improving positioning accuracy. The entire sorting mechanism operates smoothly and responds quickly, making it suitable for the co-production of various product specifications and effectively ensuring the stability and reliability of subsequent scanning, inspection, and other processes.

[0022] As a further improvement of this utility model, the incoming material counting mechanism includes a photoelectric sensor.

[0023] This invention uses a photoelectric sensor to sense incoming materials and transmits the sensing signal to a PLC control module. Based on the acquired sensing signal, the PLC control module promptly controls the sorting mechanism to perform the data accumulation and realizes the counting function.

[0024] As a further improvement of this utility model, the bottom of the production line body is provided with adjustable feet.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] like Figures 1-14 As shown, this utility model provides an automatic barcode scanning mechanism for automatically scanning products conveyed on a production line; in this embodiment, the product is an air conditioner 100, such as... Figure 14 As shown; specifically, the automatic barcode scanning mechanism includes a sorting mechanism 2 installed on both sides of the production line body 1 for aligning the conveyed products, barcode scanners 5 set on the left and right sides of the sorting mechanism 2, and an incoming material counting mechanism.

[0031] The automatic barcode scanning mechanism of this utility model automatically aligns the conveyed products by setting up sorting mechanisms on both sides of the production line, and completes product barcode scanning in conjunction with the barcode scanner. It also uses an incoming material counting mechanism to automatically count incoming materials, realizing synchronous linkage between barcode scanning and counting. This achieves automatic barcode scanning and product counting at the same time, reducing personnel input.

[0032] like Figure 13As shown, to prevent missed scans due to unclear, skewed, or other factors, the automatic scanning mechanism in this embodiment also incorporates the Internet of Things (IoT) for automatic leak prevention. Specifically, it includes a PLC control module and an IoT module electrically connected to the PLC control module. Both the IoT module and the PLC control module utilize existing technologies; this invention achieves the desired effect simply by programming existing module structures. The incoming material counting mechanism and the barcode scanner are both electrically connected to the PLC control module via a material mesh module.

[0033] A PLC control module, also known as a programmable logic controller, is a core control unit in industrial automation. It receives signals from the incoming material counting mechanism and the barcode scanner's scan results, comparing and judging the data through a preset logic program. When a discrepancy occurs between the incoming material quantity and the successfully scanned quantity, the PLC control module immediately triggers an alarm and suspends the production line. Simultaneously, it uploads the anomaly information to a cloud management system via an IoT module, enabling remote monitoring and traceability. This design effectively improves scanning accuracy and the level of intelligent production management, ensuring that 100% of air conditioners undergo complete information collection before leaving the factory.

[0034] Of course, the PLC control module can be pre-installed in the computer. Alternatively, the PLC control module can be integrated into an industrial touch screen or embedded controller for easy on-site operation and parameter adjustment.

[0035] This invention utilizes a PLC control module to centrally control the incoming material counting mechanism and the barcode scanner. The data scanned by the barcode scanner is sent to the PLC control module, and the incoming material counting mechanism transmits the product arrival signal to the PLC control module. The PLC control module performs counting and can determine whether there are missed or repeated scans based on the logical comparison between the incoming material counting signal and the scanning result. When there is a discrepancy between the two data, it is determined to be a scanning abnormality, and the production line is stopped in time to prevent missed or repeated scans from entering the subsequent process, thus realizing an automatic barcode scanning and anti-missing function.

[0036] like Figures 1-14 As shown, as a further improvement of this utility model, the sorting mechanism 2 includes a guiding component 21 and a pushing component 22; the guiding component 21 is disposed on one side of the production line body 1, and the pushing component 22 is disposed opposite to the guiding component 21 on the other side of the production line body 1.

[0037] The sorting mechanism 2 of this utility model includes a guide component 21 and a pusher component 22 arranged opposite to each other. The guide component 21 is used to guide and sort the incoming material on one side, and the pusher component 22 is located on the opposite side of the guide component 21 and is used to push and sort the incoming material on the other side, thereby realizing automatic centering and posture correction of the product during the conveying process, ensuring that the product enters the scanning area in a uniform orientation, and improving the recognition success rate of the barcode scanner 5.

[0038] As an optional embodiment of this utility model, the guiding component 21 includes a lower support frame 211, a connecting rod 213, and a guiding rod 214; wherein: The lower support frame 211 is fixed to the side of the production line body 1; The connecting rod 213 passes through the sleeve 212 at the top of the lower support frame 211; The guide rod 214 is installed at the end of the connecting rod 213.

[0039] In this embodiment, the lower support frame 211, connecting rod 213, and guide rod 214 are all made of square steel.

[0040] The guiding component 21 of this utility model is fixed by the lower support frame 211, and the guiding rod 214 is connected to the sleeve 212 at the top of the lower support frame 211 through the connecting rod 213. The structure is simple and the cost is low.

[0041] To prevent the air conditioner 100 from interfering or bumping when it enters the sorting mechanism 2, the guide rod 214 has an arc-shaped first guide part 215 facing the incoming material side.

[0042] By setting the first guide section 215, not only can the incoming material be centered and its posture corrected, but it can also avoid collision damage to the incoming material, thereby improving the level of product surface quality protection. The first guide section adopts a rounded transition structure, which smoothly guides the incoming material when it comes into contact, reduces frictional resistance, and ensures stable and efficient processing.

[0043] To improve the applicability of the mechanism and reduce the stroke of the pusher assembly 22, the connecting rod 213 is movably inserted into the sleeve 212 and can move back and forth relative to the sleeve 212. It also includes a locking member (not shown in the figure), which is disposed between the connecting rod 213 and the sleeve 212.

[0044] It should be noted that the locking element can be implemented using existing technology, such as setting a locking hole on the sleeve 212, and then using a screw as the locking element. The position is locked by the screw abutting against the connecting rod 213, and the position can be adjusted when the screw is loosened.

[0045] This utility model, by setting a connecting rod that can move back and forth and cooperating with a locking component, realizes flexible adjustment and quick fixation of the guide rod position, adapts to the centering needs of products of different specifications, and improves the versatility and ease of adjustment of the equipment.

[0046] As an optional embodiment of this utility model, the pushing assembly 22 includes a lower support 221, a telescopic cylinder 222, and a pushing plate 223; wherein: The lower support 221 is fixed to the side of the production line body 1; The telescopic cylinder 222 is fixed to the top of the lower support 221; The pusher plate 223 is installed at the end of the piston rod of the telescopic cylinder 222, and moves back and forth as the cylinder extends and retracts.

[0047] The feeding assembly of this invention uses pneumatic drive combined with a sensor to sense the material's position and trigger the feeding action in real time, thus avoiding interference with the operation of the conveyor line.

[0048] In order to further improve the posture adjustment efficiency of the air conditioner 100 and reduce the possibility of damage, the pusher plate 223 has an arc-shaped second guide part 224 on the side facing the incoming material.

[0049] By incorporating a second guide section 224, the posture of the incoming material is further adjusted. The second guide section works in conjunction with the first guide section to form a bidirectional guiding structure, ensuring smooth alignment of the incoming material during the pushing process and preventing skewing or jamming. The pusher plate, driven by a telescopic cylinder, precisely pushes the side of the product, and combined with sensor feedback, achieves closed-loop position control, further improving positioning accuracy. The entire sorting mechanism operates smoothly and responds quickly, making it suitable for the co-production of various product specifications and effectively ensuring the stability and reliability of subsequent processes such as barcode scanning and inspection.

[0050] like Figure 2 As shown, the incoming material counting mechanism includes a photoelectric sensor 4.

[0051] It also includes a frame 3, which is placed beside the production line body 1, with its top higher than the top surface of the production line body 1; a barcode scanner 5 is installed on the frame 3, located beside the product transport path, and is used to scan the barcodes of the materials after they have been processed by the feeding assembly 22, so as to realize automatic counting and information entry. The frame 3 can also be used to arrange other required components.

[0052] This invention uses a photoelectric sensor to sense incoming materials and transmits the sensing signal to a PLC control module. Based on the acquired sensing signal, the PLC control module promptly controls the sorting mechanism to perform the data accumulation and realizes the counting function.

[0053] As a further improvement of this utility model, the bottom of the production line body 1 is provided with adjustable base feet 11.

[0054] The height of the production line can be adjusted via foot 11, facilitating the connection needs of different workstations and improving the flexibility of the production line layout. The adjustable foot, combined with a level, enables quick leveling and ensures stable equipment operation.

[0055] This utility model is an automatic barcode scanning mechanism with leakage prevention function based on the Internet of Things (IoT). A guiding and pushing mechanism ensures consistent product arrival positions, facilitating automatic barcode scanning. The production line is controlled by a programmable logic controller (PLC) for counting, running, stopping, alarming, and pushing actions. The IoT module connects the barcode scanning software with the PLC, enabling data exchange and matching between the scanned data and the product detection data from the production line. Alarms are triggered for abnormalities and line stoppages, achieving automatic barcode scanning and IoT-based error prevention. Figure 14 As shown, the IT components such as scanning software, barcode scanner, and computer interact with the OT components such as field lines, photoelectric sensors, cylinders, and programmable controllers through an IoT module to prevent scanning omissions, thereby ensuring the reliability and stability of barcode scanning.

[0056] The product runs on the belt conveyor line. The guide mechanism initially adjusts the position of the product. The photoelectric sensor detects the product, and the pusher mechanism moves to push the product to the guide mechanism to ensure product consistency. The barcode scanner continuously scans and records the data. Each time the cylinder pushes the product, the programmable controller records the data internally. The IoT module matches the data from the barcode scanning software with the data recorded by the programmable controller. If the two do not match, the programmable controller controls the conveyor line to stop and alarms. If they match, the conveyor line runs normally.

[0057] like Figure 3 As shown, during operation, the air conditioner runs from right to left on production line 1, assembling its components. Photoelectric sensor 4 is installed beside production line 1. Upon arrival of air conditioner 100, a signal is detected, and the pushing component 22 in the sorting mechanism 2 pushes the air conditioner towards the guiding component 21, ensuring consistent incoming material placement for air conditioner 100. The barcode scanner 5 scans the barcode on the machine body and enters it into the production system. The signal from air conditioner 100 acquired by photoelectric sensor 4 is transmitted to the PLC control module for counting. The data is stored in the PLC register. The IoT module reads the PLC register value through a corresponding protocol. Server software installed on the computer reads the data from the IoT module. The barcode scanning software reads the server software data through a protocol and compares it synchronously with the scanned data to prevent missed scans and other anomalies, thus preventing misplacement.
