Description

Technical Field

[0001] This utility model relates to the field of labeling machine technology, specifically to a horizontal labeling machine visual precision detector. Background Technology

[0002] In today's highly automated industrial packaging production lines, horizontal labeling machines play a crucial role, widely used in the labeling process of various bottle-shaped, can-shaped, and rectangular products. Their core task is to ensure that labels adhere accurately, smoothly, and firmly to the product surface to meet the basic requirements of product identification, brand promotion, and market circulation.

[0003] Early horizontal labeling machines had a relatively simple and straightforward structural design. From a mechanical transmission perspective, they mostly used ordinary chain or synchronous belt drives to move the labeling mechanism in a straight line along the product conveying direction, thereby achieving label application. Although this transmission structure was low-cost and easy to assemble, it suffered from large speed fluctuations and strong impact forces during start-up and shutdown. This not only caused additional wear on mechanical parts and shortened the equipment's lifespan, but also made it difficult to maintain a stable rhythm during the labeling process, thus affecting labeling accuracy and often resulting in uneven initial label placement.

[0004] In terms of the deployment of visual inspection-related structures, the few existing horizontal labeling machines that attempt to introduce visual inspection often simply mount an industrial camera externally to a certain position on the machine body. The camera's installation angle and height are fixed and lack a flexible adjustment mechanism. This results in the inability to obtain clear and effective image information from all angles based on the different heights and shapes of the products, making it difficult to accurately monitor the adhesion status of the label on various product surfaces. For example, on curved products, defects such as label wrinkles and lifting are easily missed due to viewing angle issues, significantly reducing the reliability of the visual inspection system. To address these problems, we propose a horizontal labeling machine visual precision detector. Utility Model Content

[0005] The present invention aims to solve the technical problem of incomplete detection field of industrial cameras in the prior art.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A horizontal labeling machine vision precision detector includes a worktable, a guide rail fixedly connected to the top of the worktable, a labeling machine mounted on the top of the guide rail, an industrial camera mounted at the output end of the guide rail, and a control component fixedly connected to the output end of the guide rail. The industrial camera is fixed to the guide rail via the control component. The control component includes an assembly ring distributed around the guide rail. An assembly window is opened on one side of the assembly ring. An arc-shaped plate is fixedly connected to the bottom of the inner cavity of the assembly window. Multiple evenly distributed teeth are fixedly connected to the surface of the arc-shaped plate. A sliding window is opened at the top of the assembly ring. A servo motor is built into the sliding window. A drive roller is fixedly connected to the output end of the servo motor. A gear is fixedly connected to the bottom of the drive roller. The gear and the arc-shaped plate are connected through tooth meshing. A guide seat is sleeved on the surface of the servo motor. A connecting rod is fixedly connected to the bottom of the guide seat. A motion platform is fixedly connected to the bottom of the connecting rod. The top of the industrial camera is fixedly connected to the motion platform.

[0008] Preferably, a control box is installed on one side of the top of the workbench.

[0009] Preferably, the bottom of the labeling machine is fixedly connected to the workbench, and the output end of the guide rail is fixedly connected to a discharge window.

[0014] Preferably, the top of the motion platform is slidably connected to the inner ring wall of the assembly ring.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] This utility model's labeling machine vision precision detector mainly consists of a worktable, guide rail, labeling machine, industrial camera, control components, and control box. A rotating roller is installed inside the guide rail at the top of the worktable. The item to be inspected is placed on the guide rail and transported by the rotating roller. The labeling machine, fixed above the guide rail, completes the labeling as the item moves past. The control components have an assembly ring with a bottom fixing plate connected to both sides of the guide rail. One side of the assembly ring has a toothed arc-shaped plate. A servo motor is built into the top sliding window, and the motor is connected to a drive roller. The gear at the bottom of the drive roller meshes with the teeth of the arc-shaped plate. The motor is sleeved on a guide seat and connected to the motion platform of the fixed industrial camera via a connecting rod. When the labeled item reaches the output end of the guide rail, the industrial camera starts detection, and simultaneously the servo motor rotates, driving the industrial camera to move in a circle around the guide rail, achieving omnidirectional visual detection and accurately capturing defects such as label position misalignment, wrinkles, and damage.

[0017] The discharge window at the guide rail output end is used to discharge the inspected items. The entire process, coordinated by the control box, is largely automated from conveying, labeling, and inspection to discharge, reducing manual intervention, lowering labor intensity, and improving production efficiency. Furthermore, due to the adjustable motion trajectory of the industrial camera, the equipment is highly versatile and adaptable, offering fast and efficient inspection to meet the needs of large-scale production.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figures 1-5 As shown, this utility model provides a horizontal labeling machine visual precision detector, including a worktable 1, a guide rail 2 fixedly connected to the top of the worktable 1, and a plurality of evenly arranged rotating rollers 201 installed inside the guide rail 2. The item to be detected is placed on the guide rail 2 on the worktable 1, and the plurality of evenly arranged rotating rollers 201 inside the guide rail 2 start to rotate, driving the item to be transported along the guide rail 2.

[0026] The top of the guide rail 2 is equipped with a labeling machine 3, the bottom of the labeling machine 3 is fixedly connected to the workbench 1, and an industrial camera 5 is installed at the output end of the guide rail 2. When the item moves on the guide rail 2 and passes the labeling machine 3, the labeling machine 3 performs a labeling operation on the item.

[0027] Furthermore, the control component 4 includes an assembly ring 401. Fixing plates 402 are fixedly connected to both sides of the bottom of the assembly ring 401. The end faces of the two fixing plates 402 that are close to each other are fixedly connected to both sides of the guide rail 2. The assembly ring 401 is distributed around the guide rail 2. An assembly window 403 is opened on one side of the assembly ring 401. An arc-shaped plate 404 is fixedly connected to the bottom of the inner cavity of the assembly window 403. Multiple evenly distributed teeth 405 are fixedly connected to the surface of the arc-shaped plate 404. A sliding window 406 is opened at the top of the assembly ring 401. A servo motor 407 is built into the sliding window 406. The servo motor 407 outputs... A drive roller 408 is fixedly connected to the output end, and a gear 409 is fixedly connected to the bottom of the drive roller 408. The gear 409 is meshed with the arc plate 404 through teeth 405. A guide seat 410 is sleeved on the surface of the servo motor 407. The guide seat 410 is slidably connected to the inner wall of the sliding window 406. A connecting rod 411 is fixedly connected to the bottom of the guide seat 410. A motion platform 412 is fixedly connected to the bottom of the connecting rod 411. The top of the industrial camera 5 is fixedly connected to the motion platform 412. When the labeled item moves to the output end of the guide rail 2, the industrial camera 5 starts to perform visual inspection on the item. At the same time, the servo motor 407 starts, and the output end of the servo motor 407 drives the drive roller 408 to rotate. Since the gear 409 at the bottom of the drive roller 408 is meshed with the teeth 405 on the arc plate 404, it will move along the trajectory of the teeth 405 on the arc plate 404 when the gear 409 rotates. Since gear 409 is fixedly connected to drive roller 408, drive roller 408 is fixedly connected to servo motor 407, and servo motor 407 is sleeved inside guide seat 410, and guide seat 410 is slidably connected to the inner wall of sliding window 406, servo motor 407 can move along sliding window 406 on top of assembly ring 401. Servo motor 407 is fixedly connected to motion platform 412 through connecting rod 411, and motion platform 412 is fixedly connected to industrial camera 5. Therefore, during the movement of servo motor 407, it will drive industrial camera 5 to perform circular motion around guide rail 2, thereby performing all-round visual inspection of items at the output end of guide rail 2 from different angles.

[0028] The output end of guide rail 2 is fixedly connected to a discharge window 202. A control box 101 is installed on one side of the top of workbench 1. A control component 4 is fixedly connected to the output end of guide rail 2. The industrial camera 5 is fixed to guide rail 2 through control component 4. After the inspection is completed, the item is discharged through discharge window 202. The entire inspection process is controlled and coordinated by control box 101, and the components in control component 4 also work in an orderly manner under the instructions of control box 101.

[0029] Through the cooperation of components such as servo motor 407, drive roller 408, gear 409 and arc plate 404, the industrial camera 5 can move around the guide rail 2, overcoming the problem of the single detection angle of traditional industrial cameras 5, realizing all-round, no-dead-angle detection of items, greatly improving the accuracy and reliability of detection, and being able to detect various defects that may occur during the labeling process in a timely manner, such as label position deviation, label wrinkles, label damage, etc.

[0030] From conveying and labeling goods to testing and unloading, most processes are completed automatically by the equipment, reducing manual intervention, lowering labor intensity, and improving production efficiency. Meanwhile, the control box 101 controls and coordinates the entire system, making the equipment operation more stable and reliable.

[0031] The motion trajectory of the industrial camera 5 can be adjusted by controlling the rotation of the servo motor 407. The detection angle and detection range can be flexibly adjusted according to different detection needs and item specifications, which improves the versatility and adaptability of the equipment. Since the industrial camera 5 can quickly move around the guide rail 2 and perform detection, the detection time of a single item is greatly shortened, the overall detection efficiency is improved, and the needs of large-scale production can be met.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
