Description

Technical Field

[0001] This utility model relates to a rubber product inspection device, specifically a rubber product inspection device based on visual inspection that can automatically reject defective products. Background Technology

[0002] Adhesive sheets are thin sheets with an adhesive coating on one or both sides, usually made of film, paper, or other materials. They are mainly used for fixing, connecting, sealing, or protecting items and are commonly found in electronics, packaging, and daily necessities. Applying adhesive sheets to tape is a common packaging and usage method in industrial production. The core purpose is to improve efficiency and protect products: to facilitate efficient and accurate material picking and mounting by automated equipment, while preventing components from shifting, falling, or becoming contaminated during transportation and handling.

[0003] In the mounting process, if the adhesive strips on the tape have insufficient adhesion, excess adhesive, or contamination, it will cause the components to be not firmly fixed or to fail to be picked up. Therefore, it is necessary to accurately identify and remove them through the inspection station before packaging to ensure the smooth progress of subsequent automated production and the reliability of the final product soldering.

[0004] Currently, quality screening of adhesive sheets on reel mainly relies on high-precision automated vision inspection systems. These systems use high-resolution industrial cameras to continuously scan and capture images of the reel moving at a constant speed, obtaining real-time images of each adhesive sheet. Subsequently, image processing software uses specific algorithms to perform high-speed analysis and comparison of the images based on preset acceptance criteria, thereby accurately identifying defective products. Once a defective product is detected, the system immediately marks its location and can automatically remove it in subsequent processes using rejection devices. This ensures that only fully qualified adhesive sheets can proceed to the subsequent component packaging and mounting stages.

[0005] When handling defective adhesive products such as adhesive sheets transported by tape, marking tools are often used to assist in the process. Once a defective product is identified, a mark is made on the surface of the adhesive product. Subsequently, whether it is manual sorting or automated rejection equipment, the defective product can be quickly located by the mark without the need for a second full inspection of the adhesive product.

[0006] In existing technologies, common online marking solutions mostly rely on non-contact inkjet marking during the continuous movement of the tape. However, since the tape is always in motion and there is a slight delay between the issuance and execution of marking instructions, the marking position is prone to drift relative to defective products, resulting in inaccurate marking, difficulty in identification, or even accidental damage to adjacent good products. Secondly, non-contact ink marking methods are easily affected by the environment and the surface characteristics of adhesive sheets, which may cause problems such as blurry markings, splattering, poor adhesion, or complete inability to mark. Summary of the Invention

[0007] The purpose of this invention is to provide a rubber product inspection device that can automatically reject defective products based on visual inspection, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A visual inspection device for automatically rejecting defective products includes a support and an inspection table fixedly installed on the top of the support. A take-up roller and an unwind roller are arranged on the inspection table. The inspection table is connected to a drive device connected to the bottom of the inspection table. Rubber product rolls are arranged on the take-up roller and the unwind roller. A visual inspection device for visually inspecting defective products and a fixed base are arranged on the top of the support. A drive displacement mechanism and a marking component for assisting in rejecting defective products are connected to one side of the fixed base. The marking component cooperates with a guide component fixedly installed on the top of the support.

[0009] The above-described visual inspection device for automatically rejecting defective products for rubber products includes a support base connected to the top of the support and a visual inspection camera connected to one side of the support base. The visual inspection camera is positioned directly above the inspection table and works in conjunction with a driving device.

[0010] The above-described visual inspection device for automatically rejecting defective products for rubber products includes a drive displacement mechanism comprising a motor connected to one side of the fixed base and a screw connected to the output shaft of the motor, the screw being rotatably mounted on the fixed base.

[0011] The above-described visual inspection device for rubber products that can automatically reject defective products: the screw is threaded with a threaded movable seat and a bracket fixedly installed on the top of the threaded movable seat, and a slide rail is connected to the bracket.

[0012] The above-described visual inspection device for automatically rejecting defective products for rubber products includes a marking component comprising a sliding block slidably mounted on the slide rail and a fastening clamp connected to one end of the sliding block, wherein a marking pen is fixedly mounted on the fastening clamp.

[0013] The above-described visual inspection device for automatically rejecting defective products for rubber products includes a guide assembly comprising a limiting frame connected to the top of the support, wherein the limiting frame is provided with a guide groove.

[0014] The above-described visual inspection device for automatically rejecting defective products for rubber products: one end of the sliding block is connected to a roller, and one end of the roller is slidably mounted on the guide groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This device adopts an integrated structure of transmission, detection and marking. When the system identifies defective products such as insufficient adhesive, damaged substrate, or dimensional deviation, the tape transmission system will immediately trigger a stop command. At the same time, the movable marking arm with a marker pen mounted on the upper side of the device will accurately move to the position of the defective product. After positioning above the target, it will perform a vertical lifting action to make the marker pen make smooth contact with the adhesive sheet surface and complete a clear mark, providing clear guidance for centralized rejection in subsequent processes.

[0016] This invention avoids the problem of misaligned marking caused by continuous tape movement through a coordinated mechanism of transmission stop and precise positioning marking, which greatly improves the accuracy of defect marking. At the same time, the dynamic scanning capability of the visual inspection module is adapted to the tape transmission rhythm, which can cover subtle defect features and the detection accuracy is much higher than that of manual screening, reducing the risk of missed detection.

A driving displacement mechanism and a marking component for assisting in rejecting defective products are connected to one side of the fixed seat 7. The marking component cooperates with a guide component fixedly installed on the top of the support 1.

[0030] In this embodiment, the drive device 3, take-up roller 4, and unwind roller 5 drive the adhesive product roll 6 to pass through the vision inspection equipment station at a uniform speed, achieving uninterrupted online inspection and effectively improving inspection efficiency. When the vision inspection system located above the device accurately identifies a defective product, the system immediately controls the adhesive product roll 6 to stop transmission. This measure ensures the absolute stillness of the defective product's position, creating stable conditions for subsequent marking actions. Subsequently, the dedicated moving arm on the side and above drives the marking component to accurately position itself above the defective product and perform a descent action, completing reliable marking on its surface. This integrated working mode of "detection and stop, precise positioning, and contact marking" fundamentally overcomes problems such as blurred marking, position drift, or missed marking caused by continuous roll movement, significantly improving the accuracy and recognition of marking, and providing great convenience for subsequent manual or automated rejection processes, thereby improving the overall automation level and reliability of adhesive sheet quality control.

[0031] As a further embodiment of the present invention, the visual inspection device includes a support base 18 connected to the top of the support 1 and a visual inspection camera 19 connected to one side of the support base 18. The visual inspection camera 19 is positioned directly above the inspection table 2 and cooperates with the driving device 3.

[0032] In this embodiment, the visual inspection camera 19 continuously scans and captures images of the uniformly moving tape using a high-resolution industrial camera, thereby capturing images of each adhesive sheet in real time. Subsequently, the image processing software performs defective product detection on the adhesive sheets based on preset acceptance criteria. When the visual inspection camera 19 detects a defective product, it generates a signal and remotely controls the drive device 3 to stop via a remote controller located on one side of the support 1, pausing the transmission of the adhesive tape 6.

[0033] As a further embodiment of this utility model, the driving displacement mechanism includes a motor 8 connected to one side of the fixed base 7 and a screw 9 connected to the output shaft of the motor 8, the screw 9 being rotatably mounted on the fixed base 7.

[0034] In this embodiment, the output shaft of the motor 8 drives the screw 9 to rotate, and the rotation of the screw 9 will cause the fixed seat 7 to move.

[0035] As a further embodiment of this utility model, a threaded movable seat 10 and a bracket 11 fixedly installed on the top of the threaded movable seat 10 are threadedly mounted on the screw 9, and a slide rail 12 is connected to the bracket 11.

[0036] In this embodiment, when the screw 9 rotates, it will drive the threaded moving seat 10 to move. The threaded moving seat 10 and the bracket 11 move synchronously. A slide rail 12 is connected to one side of the bracket 11.

[0037] As a further embodiment of this utility model, the marking component includes a sliding block 13 slidably mounted on the slide rail 12 and a fastening clamp connected to one end of the sliding block 13, wherein a marking pen 14 is fixedly mounted on the fastening clamp.

[0038] In this embodiment, the sliding block 13 is slidably mounted on the slide rail 12, and one end of the sliding block 13 is connected to a fastening clamp, which fixes the marking pen 14.

[0039] As a further embodiment of this utility model, the guide assembly includes a limiting frame 16 connected to the top of the support 1, and the limiting frame 16 is provided with a guide groove 17.

[0040] In this embodiment, a guide groove 17 is provided on the limiting frame 16, and the guide groove 17 has a high and low undulating design.

[0041] As a further embodiment of this utility model, one end of the sliding block 13 is connected to a roller 15, and one end of the roller 15 is slidably mounted on the guide groove 17.

[0042] In this embodiment, after the conveying of the rubber product roll 6 stops, the motor 8 is started. The output shaft of the motor 8 drives the screw 9 to rotate. The rotation of the screw 9 will drive the threaded moving seat 10 and the bracket 11 to move synchronously towards the inspection table 2. Then, the roller 15 at one end of the sliding block 13 slides on the guide groove 17 of the limit frame 16. When the sliding block 13 drives the marking pen 14 close to the surface of the rubber product roll 6, the guide groove 17 guides the roller 15, so that the marking pen 14 is accurately positioned above the defective product and performs a downward action to complete a reliable marking on its surface.

[0043] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
