Description

Technical Field

[0001] This utility model relates to the field of product defect detection technology, specifically a device for automatically detecting product defects that replaces manual methods. Background Technology

[0002] Devices that detect product defects are commonly referred to as product defect detection equipment or automated defect detection systems. They are specialized devices that integrate multiple technologies, such as optics, mechanics, electronics, and computer algorithms, to automatically identify quality problems that occur in the production, processing, and assembly stages of a product, replacing or assisting manual labor. Their core objective is to accurately and efficiently detect problems such as surface scratches, cracks, stains, and dimensional deviations that do not meet quality standards before the product leaves the factory or during the production process, thereby ensuring product quality, reducing labor costs, and improving production efficiency.

[0003] In the prior art, such as the product defect detection device disclosed in announcement number CN221124340U, a base is included. An assembly groove is formed in the center of the upper surface of the base, and a stepper motor is installed inside the assembly groove. A carrier plate with a circular structure is mounted on the power output end of the stepper motor. A bracket is fixedly connected to the edge of the base, and a slotted hole is formed at the top of the bracket. Detection mechanisms are symmetrically installed at the slotted hole. It works by placing the product to be inspected on the carrier plate, and then using the power output end of the stepper motor to rotate the product via the carrier plate. Simultaneously, the extension and retraction of the movable end of the electric telescopic rod allows the inspection camera to perform vertical inspection of the product.

[0004] Existing product defect detection devices involve placing the product to be inspected on a carrier plate, then using the power output of a stepper motor to rotate the product via the carrier plate. Simultaneously, the extension and retraction of the movable end of an electric telescopic rod allows the inspection camera to inspect the product from above and below. However, manual operation is still required when loading and unloading products, which increases the labor intensity and makes the devices less practical. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Please see Figures 1-5 This embodiment provides an automatic product defect detection device to replace manual inspection, including a conveyor belt 1, a support leg 2 welded and fixed to the lower surface of the conveyor belt 1, two guide plates 3 installed above the conveyor belt 1, a detection mechanism for product inspection is provided on one side of the conveyor belt 1, a classification mechanism for product sorting is provided above the detection mechanism, and a conveying mechanism for product transport is provided on the right side of the detection mechanism.

[0030] The inspection mechanism includes a mounting base 4, a fixing plate 41, a six-axis robotic arm 42, an electric slide rail 43, a placement plate 44, a lower supplementary light 45, an inspection frame 46, an inspection camera 47, a side supplementary light 48, and a suction cup 49. The mounting base 4 is located on one side of the conveyor belt 1, and the fixing plate 41 is welded and fixed to the side wall of the mounting base 4. The six-axis robotic arm 42 is fixed to the upper surface of the fixing plate 41 by bolts.

[0031] Specifically, an electric slide rail 43 is fixed on the upper surface of the mounting base 4, and a placement plate 44 is slidably connected to the upper end of the electric slide rail 43. A suction cup 49 is installed at the end of the six-axis robotic arm 42.

[0032] Furthermore, the product can be picked up by the suction cup 49 on the six-axis robotic arm 42, and the picked-up product is placed on the placement plate 44 by the six-axis robotic arm 42.

[0033] Specifically, three inspection frames 46 are fixed to the upper end of the mounting base 4 with screws. Side supplement lights 48 are installed on the side walls of the three inspection frames 46. Inspection cameras 47 are fixed to one side of the three inspection frames 46 with screws. A lower supplement light 45 is embedded on the upper surface of the placement plate 44.

[0034] Furthermore, the lower supplemental light 45 illuminates the product, and the side supplemental light 48 mounted on the inspection frame 46 provides auxiliary illumination. At this time, the inspection camera 47 can identify product defects through area defect detection and curve defect detection. When a defect is detected by the tool, an NG signal is given. The area defect tool detects missing parts at specific locations; if a round hole is found, the product is deemed unqualified and an NG signal is given; if no defect is detected in a specific area, an OK signal is given.

[0035] In use, the conveyor belt 1 and mounting base 4 are placed in suitable positions, and the supporting legs 2 ensure the stability of the conveyor belt 1. A six-axis robotic arm 42 mounted on the fixed plate 41 is used to pick up products when they are conveyed to one side of the arm. The suction cups 49 on the arm 42 then pick up the products, which are placed onto the placement plate 44. A lower supplementary light 45 illuminates the products. A slider on the lower surface of the placement plate 44, in conjunction with an electric slide rail 43, allows for horizontal movement of the placed products, facilitating inspection. A side supplementary light 48 mounted on the inspection frame 46 provides auxiliary illumination. The inspection camera 47 identifies product defects through area defect detection and curve defect detection. When a defect is detected, an NG signal is given. An area defect tool detects missing parts at specific locations; if a round hole is found, the product is deemed unqualified and an NG signal is given; if no defect is detected in a specific area, an OK signal is given.

[0036] In summary, when this automated product defect detection device, which replaces manual labor, is in use, the lower supplementary light 45 illuminates the product, and the side supplementary light 48 on the inspection frame 46 provides auxiliary illumination. The inspection camera 47 can identify product defects through area defect detection and curve defect detection. When a defect is detected by the tool, an NG signal is given. The area defect tool detects whether there are missing parts at specific locations.

[0037] The sorting mechanism includes a discharge belt 5, a connector 51, and an NG storage bin 52. The discharge belt 5 is located on one side of the mounting base 4. A connector 51 that mates with the conveyor belt 1 is installed on one side of the discharge belt 5. An NG storage bin 52 that matches the discharge belt 5 is provided on one side of the connector 51.

[0038] Furthermore, products that give an NG signal are removed by the six-axis robotic arm 42 and placed on the discharge belt 5 corresponding to the NG storage bin 52. The defective products are then stored in the NG storage bin 52 for manual review. Qualified products are removed by the six-axis robotic arm 42 and placed on the discharge belt 5 corresponding to the connector 51, allowing them to be transported onto the conveyor belt 1. The guide plates 3 on the conveyor belt 1 then collect and transport the qualified products.

[0039] Specifically, the conveying mechanism includes a mounting frame 6, a stepper motor 61, a lead screw 62, a movable plate 63, a limiting groove 64, and a feeding box 65. The mounting frame 6 is fixed to the side wall of the conveyor belt 1 and close to the right side of the mounting base 4. One end of the mounting frame 6 is fixed to the stepper motor 61 by bolts. The power output shaft of the stepper motor 61 is fixed to the lead screw 62, and the movable plate 63 is threadedly connected to the outer surface of the lead screw 62.

[0040] Furthermore, the stepper motor 61 installed on the mounting bracket 6 drives the lead screw 62 to rotate, thereby driving the movable plate 63 to move horizontally.

[0041] Specifically, the lower surface of the movable plate 63 is slidably connected to a limiting groove 64 formed on the upper surface of the mounting frame 6, and a feeding box 65 is fixed on the upper surface of the movable plate 63.

[0042] Furthermore, the limiting groove 64 can serve as a guide, thereby conveying the products in the feeding box 65.

[0043] In use, external products are placed into the feeding box 65. The stepper motor 61 on the mounting frame 6 drives the lead screw 62 to rotate, which in turn drives the movable plate 63 to move horizontally. The limit groove 64 provides guidance, thus conveying the products in the feeding box 65. Products that give OK or NG signals are removed by the six-axis robotic arm 42. Products that give NG signals are placed on the discharge belt 5 corresponding to the NG storage box 52, and unqualified products are transported to the NG storage box 52 for storage, awaiting manual review. Qualified products are placed on the discharge belt 5 corresponding to the connector 51, so that the products are transported to the conveyor belt 1. The guide plate 3 on the conveyor belt 1 transports and collects the qualified products. The entire process does not require manual loading and unloading, making it easy to use.

[0044] In summary, when this automated product defect detection device replaces manual labor, the lower supplementary light 45 illuminates the product, and the side supplementary light 48 on the detection frame 46 provides auxiliary illumination. The inspection camera 47 can identify product defects through area defect detection and curve defect detection. When a defect is detected by the tool, an NG signal is given. The area defect tool detects missing parts at specific locations. After inspection, non-conforming products are transported to the NG storage bin 52 for storage, awaiting manual review; conforming products are removed by the six-axis robotic arm 42 and placed on the discharge belt 5 corresponding to the connector 51, allowing them to be transported to the conveyor belt 1. The guide plates 3 on the conveyor belt 1 collect and transport the conforming products. The entire process requires no manual loading or unloading.
