Description

Technical Field

[0001] The utility model relates to the technical field of automatic detection and sorting, in particular to an integrated device integrating functions of two-dimensional code information collection, dynamic weighing and one-time rejection of unqualified products, which is applicable to online information verification and weight detection scenarios of various products (such as packaging parts, components, etc.), and can be widely used in industries such as food, medicine, logistics, manufacturing, etc. that require dual control of product information and weight. Background Art

[0002] In modern industrial production, the detection of product information traceability (such as recording production batches, specifications, traceability information, etc. through two-dimensional codes) and weight compliance (such as whether it meets packaging standards, whether there are missing parts, etc.) is a key link to ensure product quality and production efficiency. For the single-function detection equipment in the market, such as two-dimensional code information collection equipment, industrial cameras are used to collect two-dimensional codes, and after parsing the information, it is judged whether it is qualified, and the unqualified ones are rejected; dynamic weighing equipment: the weight of the products in transit is detected by weight sensors, and the overweight, underweight and other unqualified products are rejected.

[0003] Currently in the market, if it is necessary to simultaneously implement two-dimensional code information detection and weight detection, two sets of independent equipment need to be configured separately, with detection units and rejection mechanisms set separately, resulting in a large floor area of the production line and high equipment costs; the product needs to go through two detection and possibly two rejection processes in sequence, the process is cumbersome, the production beat is slow, and the efficiency is low; when the two different devices are working, it is difficult to real-time associate the two-dimensional code information and weight data, and information断层 is likely to occur, which is not convenient for the full-link data traceability of the product; it is difficult to real-time associate the two-dimensional code information and weight data, and information断层 is likely to occur, which is not convenient for the full-link data traceability of the product.

[0004] Therefore, there is a need for an integrated device that can simultaneously complete two-dimensional code information collection, dynamic weighing, data correlation analysis, and realize one-time rejection of unqualified products, so as to solve the problems of cumbersome process, low efficiency and high cost in the prior art. Summary of the Invention

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and provide a device that can collect two-dimensional code data and perform dynamic weighing at one time and only needs to reject defective products once.

[0006] It should be noted that the text contains some unclear or incorrect expressions in Chinese, such as "信息断层" which is not a standard term. I have translated it as "information断层" as it is in the original text. You may need to check and correct the relevant content in the original Chinese text for a more accurate translation.To achieve the above objectives, this utility model adopts the following technical solution: a QR code acquisition and association simultaneous dynamic weighing device, including a weighing belt, the weighing belt having three sections, each section consisting of belt A and two side belt mounting plates A, a code reader bracket mounted on the belt mounting plate A, the belt mounting plate A being vertically fixed to both ends of the code reader bracket, a code reader camera mounted on the code reader bracket, the code reader camera being mounted on one side of the code reader bracket, a flip-top rejection mechanism mounted on the third section of the weighing belt, the recycling bin of the flip-top rejection mechanism being horizontally fixed to both sides of the belt mounting plate C, the recycling bin... A tilting shaft is installed inside, with both sides of the tilting shaft perpendicularly fitted to the inner wall of the recycling bin. A cover plate is installed on the tilting shaft, with one side of the cover plate bent to fit against the tilting shaft. A weighing belt bracket is installed below the weighing belt, and the weighing belt bracket and weighing belt are vertically installed and fixed. Casters and leveling feet are installed below the weighing belt bracket, and the casters and leveling feet are vertically installed and fixed to the weighing belt bracket. A weighing controller is placed behind the weighing belt, and a weighing detection touch screen is installed on the industrial controller. A counting and correlation belt is placed parallel to the tail of the weighing belt, and the counting and correlation belt consists of two belts D and two side belts. The system comprises a mounting plate D, a counting camera bracket mounted on the counting-related belt, the counting camera bracket being vertically fitted below the counting-related belt, a counting camera mounted on the counting camera bracket, the counting camera being vertically fitted to the counting camera bracket, two roller flattening mounting plates mounted on the counting-related belt, rollers mounted on the roller flattening mounting plates, the rollers being perpendicular to one side of each roller flattening mounting plate, adjusting brackets mounted on both sides of the counting-related belt, the adjusting brackets being perpendicular to the two counting-related belt mounting plates on both sides, a collection frame mounted at the tail of the counting-related belt, the long plates on both sides of the collection frame being parallel to the two counting-related belt mounting plates on both sides, the bottom of the adjusting bracket mounted on the counting-related belt bracket, the counting-related belt bracket being vertically fitted and fixed to the adjusting bracket, a counting display mounted on the counting-related belt bracket, the counting display being vertically fitted to the counting-related belt bracket, casters and foot cups mounted on the counting-related belt bracket, the casters and foot cups being vertically fitted and fixed to the counting-related belt bracket, and an industrial control platform placed in front of the counting-related belt.

[0007] The technical advantages of adopting the above-mentioned further solution are as follows: The product is weighed and its data is collected by a barcode reader camera on the weighing belt. The product information is then fed back to the industrial control platform. The platform processes the information; qualified products do not need to be rejected, while defective products are rejected. Qualified products are counted and grouped for statistical analysis. During the process, after preliminary adjustments and testing, work can begin immediately. One worker is required to place products before testing and collect products after testing. No manual operation or equipment adjustment is needed during the testing process, thus improving work efficiency and reducing labor costs.

[0008] The technical effect of adopting the above-mentioned further solution is that by adjusting the slots on the adjustment bracket, the position of the counting-related belt is adjusted so that it is parallel and symmetrical with the weighing belt, ensuring that the product passes smoothly. The operation is simple and convenient for staff to adjust.

[0009] In a preferred embodiment, the QR code collection and detection and dynamic weighing detection only require one rejection of the product, without the need for a second rejection.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, when QR code collection and weight detection of a product are required, both data can be detected simultaneously, eliminating the need for a second detection and removal of defective products. The product is placed into the first section of the weighing conveyor belt, where a camera collects and detects any abnormal data. After camera detection, the product moves to the next section of the weighing conveyor belt for weight detection to check for overweight or underweight. If errors occur in the QR code detection information, weight, or both, the product is removed by a flip-top rejection mechanism on the third section of the weighing conveyor belt. The cover opens, and the defective product falls into the recycling bin. If no errors occur, the product proceeds to the next step. The product enters the counting-related conveyor belt, where a counting camera collects data. The product is then flattened by rollers and collected by a collection frame at the end of the counting conveyor belt. Once a group of products has been counted, the group in the collection frame is complete and finally falls onto the counting-related conveyor belt support platform, completing the entire process.

[0011] This invention integrates QR code information collection, dynamic weighing, and automatic data rejection into a single system, enabling products to undergo dual inspection in a single pass, significantly shortening production cycle time. Based on data synchronization with the industrial control platform, it can accurately reject all defective products (those failing in one or both information / weight items) in a single operation, avoiding efficiency losses and product damage caused by repetitive operations. Simultaneously, the system establishes a real-time bidirectional correlation archive between product QR code information and weight data, forming a complete and traceable quality database. Compared to traditional split-type equipment, this solution has a more compact structure, reducing equipment procurement, installation, and maintenance costs, making it particularly suitable for space-constrained production lines. The industrial control platform supports flexible configuration of inspection standards (such as QR code parsing rules, weight thresholds, etc.), quickly adapting to the inspection needs of different product specifications, achieving convenient, fast, and universal results.
