Description

Technical Field

[0001] This invention relates to the field of light guide strip processing equipment technology, and more specifically, to a label inspection mechanism. Background Technology

[0002] Light guide strip testing agencies typically test the light emission of light guide strips, which is a functional test. However, during the production and operation of enterprises, labels are usually affixed to each light guide strip. There are clear requirements for the number of labels and the distance between each label, which are also clear internal standards. However, it is difficult to verify these standards during the production process.

[0003] Currently, the market-available light guide strip intensity testing machine (Chinese patent application number 201921004927.7 discloses a novel light guide strip intensity testing machine) includes a frame comprising a support column A, a base, a support column B, and a top plate. One end of support column A is fixedly connected to one side of the upper surface of the base, and one end of support column B is fixedly connected to the other side of the upper surface of the base. One end of the top plate is fixedly connected to the other side of support column A, and the other end of the top plate is fixedly connected to the other side of support column B. The combination of support column A, base, support column B, and top plate forms an inner cavity. This novel light guide strip intensity testing machine also includes a motor, a rotating disk, a working disk, a guiding lifting mechanism, positioning fixtures, springs, and a cylindrical cover. Although this testing machine has the function of detecting brightness, its detection structure is relatively complex and it cannot perform inspection of labels. Summary of the Invention

[0016] Reference Figures 1 to 4 The embodiments of the present invention will be further described below.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and 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 this invention.

[0019] When in use, the light guide strip is placed in the housing 301301 on the transfer seat 201. The housing 301301 contains the conveyor frame 401401. First, one end of the light guide strip is placed into the sponge block 601601 and the contact end of the conveyor belt 403. This facilitates the conveying process. At this time, there is no light source. After the end is conveyed out, the power needs to be turned on manually, and the entire light guide strip will light up. The inspector needs to check through the mirror 202 whether the uninspected section is lit up.

[0020] The light guide strip enters and exits through openings at both ends of the housing 301. A conveyor frame 401 is installed inside the housing 301, and the light guide strip is transported by a conveyor belt 403 on the conveyor frame 401. A rotary motor 402 drives the conveyor belt 403 to rotate. The light-emitting surface of the light guide strip is positioned between adjacent protrusions, achieving transport through this locking method to prevent misalignment. A sealed box 701 is installed inside the frame, and a light source sensor 702 is built into a sealed compartment within the sealed box 701. When the conveyor belt 403 transports the light guide strip, the light from the light guide strip passes through the light-transmitting hole 405 and shines into the sealed compartment of the sealed box 701, illuminating the light source sensor 702. 2. Upon sensing light, feedback is sent to the host. Simultaneously, the sponge block 601 at the top of the housing 301 compresses the light during transport, preventing external light sources from entering. Light source detection is performed during transport. After transport, the end of the light guide strip is connected to the power connector 807, which supplies power to the light guide strip. The rotation of the motor causes the rotating wheel 802 on the rotating frame 801 to rotate, thus completing the winding of the light guide strip. The light guide strip wraps around the outside of the rotating rod. During winding, the camera 901 performs image detection on the labels on the light guide strip to check for any missing labels.

[0021] The rotating wheel 802 is formed by two metal rings 8022, several U-shaped metal rods 8023, two second metal rings 8021, and a bearing 803, creating a hollow rotating wheel 802. The bearing 803 is connected to one of the second metal rings 8021, allowing the light guide strip to be directly inserted into the power connector 807 during processing, which is convenient. The bearing 803 is fitted onto the rotating rod, and the outer wall of the bearing 803 has several circumferentially arranged tooth marks, which facilitates its engagement with the gear 806 at the motor output end for easy driving.

[0022] Main processor: collects information from the sensing module, the image recognition module, and the real-time module, and controls the power supply to be turned on and off; Sensing and receiving module: Receives data fed back by light source sensor 702; Image recognition module: identifies tags in real-time video recordings from camera 901; Timing module: times the data received by the sensing and receiving module.

[0023] The main processor reads the feedback from the light source sensor 702 of the sensing module. If there is no light source, it indicates a damage and the main processor will issue a damage warning on the interface. During image recognition, if there are missing or damaged labels, the main processor will also issue a missing label warning on the main interface. The timing module times the light source sensing time and a single light guide strip. If no label is detected within a fixed time range, the main processor will issue a missing label warning on the interface and shut down the motor until it restarts.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.
