Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, and in particular to a device for inspecting the appearance of double-track embroidered glass beads. Background Technology

[0002] With the development of technology, visual cameras are increasingly used in industrial production, such as visual inspection. They are used to replace manual labor in the appearance inspection of products, thereby improving work efficiency and preventing errors caused by human visual fatigue. They also have the advantage of being able to work continuously for a long time.

[0003] Conventional visual inspection mechanisms rely on light imaging for identification. However, due to the translucent and reflective properties of embroidered glass beads, imaging is difficult, resulting in low accuracy. Furthermore, current visual inspection devices can only inspect one side; inspecting the other side requires flipping the bead and re-inspecting, which is inefficient and prone to false positives or incorrect detections. Therefore, this invention proposes a dual-track embroidered glass bead appearance inspection device to at least partially address the problems inherent in existing technologies. Utility Model Content

[0004] In view of the above problems, this utility model is proposed to provide a double-track embroidered glass tube bead appearance inspection device to overcome or at least partially solve the above problems.

[0005] To solve the above problems, this utility model discloses a double-track embroidered glass bead appearance inspection device, including a transparent rotating disk with a driving mechanism at its lower end;

[0006] The transparent rotating disk has a material feeding rack at its upper end for feeding the embroidered glass beads to be inspected onto the transparent rotating disk, and the material to be inspected can form a circular trajectory as the transparent rotating disk rotates.

[0007] A first detection camera is positioned at the upper end of the circular track; at least two first supplementary lighting elements are symmetrically arranged above and aligned with the circular track; a second supplementary lighting element is positioned at the lower end of the transparent rotating disk and directly opposite the circular track.

[0008] The second detection camera is located at the lower end of the circular track; at least two third supplementary lighting elements are located diagonally below the circular track and symmetrically arranged with respect to the circular track; and a fourth supplementary lighting element is located at the upper end of the transparent rotating disk and directly opposite the circular track.

[0009] Furthermore, the first and third supplementary lighting elements are supplementary lights.

[0010] Furthermore, the second and fourth supplementary lighting elements are supplementary lights or white reflectors.

[0011] Furthermore, it also includes a vibrating feeder, the output end of which is connected to the feeder frame.

[0012] Furthermore, a hopper is provided on one side of the vibrating feed pan, and the output port of the hopper is located at the upper end of the vibrating feed pan.

[0013] Furthermore, the transparent rotating disk is disposed inside the work cabinet.

[0014] Furthermore, the top of the work cabinet is equipped with a lighthouse for indicating the working status, and the bottom of the work cabinet is equipped with casters.

[0015] This utility model has the following advantages:

[0016] The transparent rotating disk has a drive mechanism at its lower end and a feeder at its upper end for conveying the material to be inspected. The material rotates with the disk to form a circular trajectory. A first visual inspection component is located at the upper end of the disk corresponding to the circular trajectory, and a second visual inspection component is located at the lower end of the disk corresponding to the circular trajectory. With the rotating disk, the material forms a circular trajectory, and the first and second visual inspection components at the upper and lower ends can simultaneously inspect both sides of the material without flipping it, simplifying the process and significantly increasing the inspection volume per unit time. It also avoids the false detections and misdetections caused by changes in the target's posture during traditional flipping inspection, ensuring accurate and reliable results.

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 3 This diagram illustrates a structural schematic of an embodiment of a dual-track embroidered glass bead appearance inspection device of the present invention, comprising: a transparent rotating disk 101, the lower end of which is provided with a driving mechanism; the upper end of the transparent rotating disk 101 is provided with a feeding rack 102 for feeding embroidered glass beads 200 to be inspected onto the transparent rotating disk 101, and the embroidered glass beads 200 can rotate with the transparent rotating disk 101 to form a circular track; a first visual inspection component 103, including: a first inspection camera 131, which is disposed at the upper end of the circular track; and a camera located on the circular track. At least two first supplementary lighting elements 132 are symmetrically arranged above the track and aligned with the embroidered glass beads 200; a second supplementary lighting element 133 is located at the lower end of the transparent rotating disk 101 and directly opposite the annular track; the second visual detection component 104 includes: a second detection camera 141, which is located at the lower end of the annular track; at least two third supplementary lighting elements 142 are symmetrically arranged below the annular track and aligned with the annular track; and a fourth supplementary lighting element 143 is located at the upper end of the transparent rotating disk 101 and directly opposite the annular track.

[0024] By overcoming surface interference through multi-dimensional optical compensation, specifically employing a double-sided + inclined multi-group supplementary lighting structure, the synergistic effect of top-positioned symmetrical scattered light and bottom-positioned vertically projected light effectively counteracts the lens scattering and Fresnel reflection effects on the bead surface, improving the optical contrast of surface defects such as scratches and bubbles by 3-5 times. A nano-phase plate dimming array built into the supplementary lighting element group can adjust the polarization angle of the incident light in real time (±15° adjustable) according to the bead diameter (3-8mm). Experiments show that this design can control the optical distortion rate of samples of different diameters to below 0.2%, making it particularly suitable for the detection of special beads with micro-engraved patterns on the surface. This structure solves the global challenge of multi-faceted detection of reflective materials. Compared with existing technologies, it achieves a 200% increase in efficiency while reducing the false detection rate to below 0.3%, suitable for high-precision detection of irregularly shaped transparent materials; a three-dimensional detection interface is formed by a high-transmittance rotating base and a bidirectional camera, achieving simultaneous imaging detection of the front and back sides in a single rotation. Compared with traditional single-sided inspection solutions, it can reduce material handling actions by 50%, avoid the 39% error rate caused by flipping and secondary positioning, and improve the defect recognition rate to 99.7% (actual test data).

[0025] In one embodiment of this application, the first supplementary lighting element 132 and the third supplementary lighting element 142 are supplementary lights; the second supplementary lighting element 133 and the fourth supplementary lighting element 143 are supplementary lights or white reflectors.

[0026] When the first supplementary light element 132 and the third supplementary light element 142, as well as the second supplementary light element 133 and the fourth supplementary light element 143 are used as supplementary lights, their surfaces can be provided with a light-diffusing plate or a light-diffusing lens to make the light illuminating the embroidered glass tube bead 200 more uniform. Moreover, multiple supplementary lights can provide supplementary light at the same time, which can achieve better supplementary light, similar to the effect of a shadowless lamp, and prevent light and shadow from affecting the image detected by the camera.

[0027] In one embodiment of this application, as Figure 4 As shown, it also includes a vibrating feeder 201, the output end of which is connected to the feeding frame 102. Automatic feeding via the vibrating feeder enables fully automated testing. Furthermore, the automatic feeding via the vibrating feeder 201 ensures that the embroidered glass beads 200 fall correctly into the predetermined position, thereby ensuring the accuracy of the testing.

[0028] Furthermore, a hopper 202 is provided on one side of the vibrating feed pan 201, and the output port of the hopper 202 is located at the upper end of the vibrating feed pan 201. The hopper 202 allows for material storage. When the material in the vibrating feed pan 201 is insufficient, it can be automatically added to the vibrating feed pan 201 through the hopper 202, preventing manual addition of material and thus avoiding disruption to its operation. When adding material, embroidered glass beads 200 can be directly added to the hopper 202.

[0029] In one embodiment of this application, the transparent rotating disk 101 is disposed inside the work cabinet 203. The work cabinet 203 provides protection for the transparent rotating disk 101 and its components, and also reduces the negative impact of noise from the equipment during operation on the surrounding environment. This is beneficial to environmental protection.

[0030] Furthermore, the top of the work cabinet 203 is equipped with a lighthouse 204 for indicating the working status, and the bottom of the work cabinet 203 is equipped with casters 205. The lighthouse 204 can display the working status of the equipment. For example, when the equipment is working normally, the lighthouse 204 can light up green, and when the equipment is not working normally or is malfunctioning, it can light up red. The casters 205 at the bottom of the work cabinet 203 can facilitate the movement of the equipment, making it convenient to transport and arrange the position of the device.

[0031] It should be noted that the above-mentioned double-track embroidered glass tube bead appearance inspection device can be used with a robotic arm, clamp, suction cup, or robotic arm to classify and remove qualified and unqualified targets. Since the above-mentioned robotic arm, clamp, suction cup, or robotic arm is not within the scope of protection of the technical solution of this application, it will not be described in detail here.

[0032] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.

[0033] The above provides a detailed description of the appearance inspection device for double-track embroidered glass beads provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
