Description

Technical Field

[0001] This utility model relates to the field of defect detection technology, specifically a device for detecting defects on the surface of fiberglass cloth. Background Technology

[0002] The fiberglass cloth surface defect detection device is a specialized device for the automated detection of surface defects in fiberglass fabrics. It combines optical, image processing and machine learning technologies to achieve rapid and accurate identification and classification of various defects in the fiberglass cloth production process.

[0003] Existing technology, patent document CN222379478U, discloses a fiberglass cloth defect detection device, comprising a hollow housing on one side forming a working groove. A detection unit for detecting the tensile state of the fiberglass cloth is fixedly connected to the upper inner wall of the working groove. A conveying mechanism for transporting the fiberglass cloth is located below the detection unit in the working groove. Beneficial effects: The conveying mechanism allows for simultaneous transport and tensile testing of the fiberglass cloth, facilitating continuous transport and inspection. If the fiberglass cloth has defects (e.g., metal wires, hollow areas, uneven weaving), it will cause uneven distribution of tensile force, leading to damage when the fiberglass cloth is stretched. The detection unit can then trigger an alarm to locate the defective area.

[0004] Although the device has many beneficial effects, it still has the following problems: During the use of the device, there is a preceding process that connects to the testing device, which means that the device lacks an independent testing mechanism for fiberglass cloth rolls, resulting in low versatility in testing. Secondly, the testing part of the device is directly exposed to the air, and there is no cleaning device before it is sent for inspection. When the surface of the fiberglass cloth is contaminated with dust or particles, it may cause the testing device to misjudge the surface of the fiberglass cloth, resulting in poor cleaning effect. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues, the device requires a pre-process connection to the testing equipment, resulting in a lack of a separate testing mechanism for fiberglass cloth rolls, leading to low versatility in testing. Furthermore, the testing section is directly exposed to the air, lacking a cleaning device before inspection. This can cause misjudgments by the testing equipment when dust or particulate matter adheres to the fiberglass cloth surface, resulting in ineffective cleaning.

[0008] Therefore, the purpose of this utility model is to provide a fiberglass cloth surface defect detection device. A compression screw is threadedly connected inside the stabilizing frame. A section of the take-up or unwound drum is first installed. Then, the mounting block is aligned with the combined rotating shaft with the mounting groove. After alignment, the compression screw is turned to install the take-up or unwound drum between the two support frames. Through the interaction of the take-up and unwound devices, independently wound fiberglass cloth materials can be detected, offering good versatility. Furthermore, the detection section of the device is enclosed to prevent particles from entering and adhering to the fiberglass cloth surface. Simultaneously, when the fiberglass cloth is conveyed into the detection section, a brush on the magnetic plate cleans the surface, removing particles or dust that adhered before being conveyed to the detection section, thereby reducing the possibility of misjudgment by the detection equipment and achieving good cleaning results.

[0009] 2. Technical Solution:

[0010] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0011] A fiberglass cloth surface defect detection device includes a detection frame with two stabilizing frames fixedly connected to both sides. One stabilizing frame houses a take-up drum, and the other stabilizing frame houses an unwinding drum. One end of the take-up drum is connected to a drive motor via a rotating shaft, and the other end is fixedly connected to a mounting block. Both stabilizing frames have threaded holes inside, and a pressing screw is threaded into each threaded hole. The bottom end of the pressing screw is connected to a combined rotating shaft via a rotating shaft. The bottom of the combined rotating shaft has a mounting groove, and a mounting block is installed inside the mounting groove.

[0012] In a preferred embodiment of the fiberglass cloth surface defect detection device of this utility model, partitions are fixedly connected to both sides of the detection frame, and magnetic grooves are provided at the bottom of the partitions. Magnetic plates are magnetically connected inside the magnetic grooves, and brushes are fixedly connected to the bottom of the magnetic plates. First fixing plates are fixedly connected to both sides of the detection frame. A servo motor is fixedly connected to the front of the first fixing plate, and a lead screw is connected to the bottom of the servo motor via a rotating shaft. One end of the lead screw is connected to a second fixing plate via a rotating shaft. A sliding rod is fixedly connected to the back of the first fixing plate, and a moving block is threaded onto the surface of the lead screw. A scraper is fixedly connected to the bottom of the moving block.

[0013] As a preferred embodiment of the fiberglass cloth surface defect detection device of this utility model, the front of the detection frame is provided with a display screen, and the four corners of the bottom of the detection frame are fixedly connected with legs, so that the device can be placed stably on the ground by the legs at the four corners of the bottom of the detection frame.

[0014] As a preferred embodiment of the fiberglass cloth surface defect detection device of this utility model, the detection frame is fixedly connected to both sides of the detection frame, and the inside of the storage frame is provided with an inner cavity. By placing the independent fiberglass cloth roll to be detected or the independent fiberglass cloth roll that has been detected and rolled up inside the inner cavity of the storage frame, it is convenient for staff to operate in a centralized manner.

[0015] As a preferred embodiment of the fiberglass cloth surface defect detection device of this utility model, the inside of the detection frame is connected to a conveyor roller via a rotating shaft. The top and bottom surfaces of the detection frame are fixedly connected to a detection component. A supplementary light is fixedly connected to the top of the detection component. The conveyor roller inside the detection frame also has a certain transmission function, which facilitates the device to perform rapid detection. The detection component includes a camera with selectable accuracy mode and a dedicated image processing system, which facilitates the processing and extraction of target features to generate and detect results.

[0016] In a preferred embodiment of the fiberglass cloth surface defect detection device of this utility model, a support frame is fixedly connected to the side of the storage frame, and a support plate is fixedly connected to the top of the support frame. The drive motor can be stably fixed to the top of the pad by the support plate fixedly connected to the top of the support frame.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This fiberglass cloth surface defect detection device uses stabilizers fixedly connected to both sides of the detection frame. Different rolls can be installed inside the stabilizers that serve different functions. An unwinding roll is installed inside one stabilizer, and a winding roll is installed inside another stabilizer with a drive motor. With the help of a mounting block at one end of the winding roll and a combined rotating shaft with a mounting groove, the winding roll and the unwinding roll can be installed in their respective positions. The independent fiberglass cloth rolls can be inspected by the winding roll and the unwinding roll, making the device highly versatile.

[0021] This fiberglass cloth surface defect detection device consists of partitions fixedly connected to both sides of the detection frame, and magnetic plates fixedly connected to the bottom of the partitions. Numerous tiny brushes are fixed to the bottom of the magnetic plates. During the process of feeding the fiberglass cloth into the detection frame, dust or airborne particles may adhere to the surface of the fiberglass cloth, causing misjudgment during detection. The brushes can then remove the particles and dust adhering to the surface of the fiberglass cloth. The brushed-off dust will either accumulate on the brushes or fall onto the fiberglass cloth and be repeatedly brushed off. A servo motor-driven moving block can continuously scrape the surface of the fiberglass cloth with a scraper, causing the dust or particles brushed off to fall naturally to one side. The magnetic plates inside the partitions are easily replaceable; when the brushes become too dirty, they can be easily replaced with new ones. The scraper structure also allows for direct wiping and cleaning at the end of the detection process, preventing misjudgment by the detection components due to dust and particles adhering to the fiberglass cloth surface. The cleaning effect is good. Attached Figure Description

A moving block 28 is threadedly connected to the surface of the lead screw 30. A scraper 29 is fixedly connected to the bottom of the moving block 28.

[0038] Next, in order to facilitate the stable placement of the device on the ground, specifically, a display screen 2 is provided on the front of the detection frame 1, and four legs 3 are fixedly connected to the bottom corners of the detection frame 1.

[0039] Meanwhile, to facilitate the installation process of the independent take-up drum 12 and unwind drum 13, specifically, storage frames 6 are fixedly connected to both sides of the detection frame 1, and the storage frames 6 have an inner cavity 7 inside.

[0040] Furthermore, in order to improve the detection efficiency of the detection device, specifically, the inside of the detection frame 1 is connected to a conveyor roller 4 via a rotating shaft, and the top and bottom surfaces of the detection frame 1 are fixedly connected to a detection component 5.

[0042] Finally, in order to facilitate the drive motor 19 to drive the winding drum 12, specifically, a pad 10 is fixedly connected to the top of the support plate 9, and a drive motor 19 is fixedly connected to the top of the pad 10.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-5 The specific usage process of the fiberglass cloth surface defect detection device of this embodiment is as follows:

[0045] 1: When using this fiberglass cloth surface defect detection device, the device should first be placed stably in the required position. After confirming that the position is correct, the device can be placed in that position. By using the four support points generated at the four corners of the bottom of the detection frame 1, it is ensured that the device is not prone to misalignment of the winding drum 12 and the unwinding drum 13 due to its own vibration during operation, and the stability is good.

[0046] 2: After placement, the individual fiberglass cloth rolls can be installed inside the take-up and unwinder. The extrusion screw 17 is pre-unscrewed, and then one end of the take-up drum 12 and the unwind drum 13 is installed inside the stabilizer 11. Then, the mounting blocks 14, which are fixedly connected to the sides of the take-up drum and the unwind drum 13, are aligned with the mounting grooves 15. The extrusion screw 17 is then tightened, and the mounting blocks 14 are installed inside the combined rotating shaft 16. The take-up drum 12 is driven by the drive motor 19 on the side of the take-up machine to take up and pull the fiberglass cloth on the surface of the unwind drum 13, so that the fiberglass cloth on the surface of the take-up drum 12 is rolled onto the surface of the take-up drum 12. This allows for the detection of individual fiberglass cloth rolls, which has good versatility.

[0047] 3. When the take-up drum 12 pulls the fiberglass cloth, the fiberglass cloth will slowly enter the detection area. During this process, dust or particles may adhere to the surface of the fiberglass cloth. If dust and particles enter the detection part along with the cloth, it may cause the detection system to make a misjudgment. At this time, the magnetic suction plate 21 and the brush 22 can be magnetically connected on both sides of the detection frame 1 through the partition plate 20 to clean the surface of the fiberglass cloth entering the detection area and brush off the dust or particles. At the same time, the screw 3 mechanism, which is fixedly connected on both sides of the detection frame 1 through the first fixing plate 24 and the second fixing plate 25, is activated, and the servo motor drives the mechanism. Driven by 26, the scraper 29 repeatedly scrapes the surface of the fiberglass cloth, scraping away dust or particles that have been scraped off by the brush 22 but are not stuck to its surface, allowing them to fall naturally to the ground. Since the partition 20 and the magnetic plate 21 are connected via the magnetic groove 23, even if the brush 22 becomes unable to clean the fiberglass cloth properly after long-term use, the entire brush 22 and magnetic plate 21 can be replaced together. Furthermore, at the end of the entire inspection process, the scraper 29 can be wiped clean separately to prevent it from entering the inspection area and causing misjudgment by the device, resulting in a good cleaning effect.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
