Description

Technical Field

[0001] This utility model relates to a defective product identification device, specifically a defective product identification device for a factory production line, and belongs to the technical field of identification and detection devices. Background Technology

[0002] Defective product identification devices are mainly machine vision inspection equipment. They can replace traditional manual quality inspection. Through high-precision optical sensors and image processing algorithms, they can quickly and accurately detect various defects on the surface of products, such as scratches, damage, cracks, dents, stains, etc. They can also detect defects such as mixed materials, different colors, incorrect or missing parts, and poor characters, ensuring that the appearance and dimensions of the products meet the standards. Machine vision inspection equipment is applicable to a variety of industries and products, such as electronic components, plastic parts, silicone parts, hardware parts, automotive parts, textiles, and paper.

[0003] A Chinese utility model patent (publication number: CN219870977U) discloses an appearance quality inspection device for small household appliance production. This device automates the appearance quality inspection process by employing a CCD industrial vision camera and an automated adjustment mechanism, thereby improving production line efficiency and capacity. The camera's high-speed image processing capabilities and the precise control of the adjustment mechanism enable a fast and accurate inspection process, meeting the needs of large-scale production.

[0004] While it effectively identifies product appearance defects, the way its vision camera is installed limits its recognition performance to some extent.

[0005] Specifically, vision cameras are usually installed vertically above the production line. While this layout facilitates image acquisition from the top of the product, it falls short when acquiring images from the four sides. Due to the limitations of the camera's field of view, the acquisition of side images is often poor, resulting in a lower recognition rate of side defects and thus affecting the overall recognition effect. To address this, a defect identification device for factory production lines is proposed. Utility Model Content

[0006] In view of this, the present invention provides a defective product identification device for a factory production line to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model embodiment is implemented as follows: a defective product identification device for a factory production line includes a support frame, and a detection and identification component is installed on the inner top wall of the support frame. The detection and identification component includes two mounting frames, a side identification camera, a mounting base, a main identification camera, a servo motor, a mounting rod, two limit sleeves, an incomplete gear, a drive shaft, a limit shaft, and two clock springs.

[0008] Two mounting brackets are symmetrically fixedly connected to both sides of the mounting base. The side recognition camera is mounted on the end of the mounting bracket away from the mounting base. The servo motor is mounted on one side of the mounting base. The incomplete gear is fixedly connected to the outer wall of the drive shaft. The top of the mounting rod is fixedly connected to the outer wall of the limiting shaft. Two spring-loaded springs are symmetrically sleeved on the outer wall of the limiting shaft. Two limiting sleeves are symmetrically fixedly connected to both sides of the inner wall of the mounting base. The main recognition camera is mounted at the bottom of the mounting rod.

[0009] More preferably, the drive shaft is rotatably connected to the inner side wall of the mounting base, and one end of the drive shaft is fixedly connected to the output shaft of the servo motor.

[0010] More preferably, the top end of the mounting rod is provided with teeth that are adapted to the incomplete gear, and the top end of the mounting rod is engaged with the teeth on the incomplete gear.

[0011] More preferably, the limiting shaft is rotatably connected to the inner side wall of the mounting base, and both the limiting shaft and the spring are located inside the limiting sleeve.

[0012] More preferably, one end of the spring is fixedly connected to the limiting shaft, and the other end of the spring is fixedly connected to the inner wall of the limiting sleeve.

[0013] More preferably, the two side recognition cameras are symmetrically and obliquely positioned on both sides of the mounting base.

[0014] More preferably, the bottom of the support frame is fixedly connected to two bases.

[0015] More preferably, a conveyor is provided below the support frame, and the support frame is mounted on the frame of the conveyor via a base.

[0016] The present invention has the following advantages due to the adoption of the above technical solution:

[0017] This invention uses a servo motor to drive the drive shaft to rotate. With the cooperation of an incomplete gear, a mounting rod, and a limiting shaft, the angle of the main recognition camera can be adjusted. Simultaneously, in conjunction with side recognition cameras, defects can be identified on the top surface and four sides of the product. When the angle of the mounting rod is less than -50°, the teeth of the incomplete gear separate from the teeth at the top of the mounting rod. At this point, driven by a spring, the mounting rod resets, allowing for defect identification of the next product. Compared to existing technologies, this invention, by adjusting the angle of the main recognition camera and cooperating with two side recognition cameras, can acquire images of the top surface and four sides of the product, thus ensuring effective defect identification.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-4As shown, this utility model embodiment provides a defective product identification device for a factory production line, including a support frame 11. A detection and identification component 101 is installed on the inner top wall of the support frame 11. The detection and identification component 101 includes two mounting brackets 12, a side identification camera 13, a mounting base 14, a main identification camera 15, a servo motor 16, a mounting rod 17, two limit sleeves 18, an incomplete gear 19, a drive shaft 20, a limit shaft 21, and two spring springs 22.

[0028] Two mounting brackets 12 are symmetrically fixed to both sides of the mounting base 14. The side recognition camera 13 is installed at the end of the mounting bracket 12 away from the mounting base 14. The two side recognition cameras 13 are symmetrically obliquely placed on both sides of the mounting base 14. The main recognition camera 15 is installed at the bottom of the mounting rod 17. The two side recognition cameras 13 can capture images of the two sides of the product and identify defects on the two sides of the product. The main recognition camera 15 can capture images of the front, top and back of the product and identify defects, thereby ensuring the recognition rate of defects on the four sides and improving the overall recognition effect.

[0029] Both the side recognition camera 13 and the main recognition camera 15 are CCD industrial vision cameras. Their defect recognition principles and internal structures are existing technologies, so they will not be described in detail here.

[0030] The servo motor 16 is mounted on one side of the mounting base 14. The incomplete gear 19 is fixedly connected to the outer wall of the drive shaft 20. The drive shaft 20 is rotatably connected to the inner wall of the mounting base 14. One end of the drive shaft 20 is fixedly connected to the output shaft of the servo motor 16. When the servo motor 16 is working, the servo motor 16 drives the drive shaft 20 to rotate, and the drive shaft 20 drives the incomplete gear 19 to rotate, which can realize the angle adjustment of the main recognition camera 15.

[0031] The top of the mounting rod 17 is provided with teeth that are adapted to the incomplete gear 19. The top of the mounting rod 17 is engaged with the teeth on the incomplete gear 19. The limiting shaft 21 is rotatably connected to the inner wall of the mounting base 14. The limiting shaft 21 and the spring 22 are both located inside the limiting sleeve 18. The servo motor 16 drives the drive shaft 20 to rotate. The drive shaft 20 drives the incomplete gear 19. The incomplete gear 19 drives the mounting rod 17 through the teeth. The mounting rod 17 rotates through the limiting shaft 21. When the mounting rod 17 rotates, it drives the main recognition camera 15, thereby allowing the angle of the main recognition camera 15 to be adjusted.

[0032] When the product is in front of the main recognition camera 15, the angle of the mounting rod 17 is 50°, and the image is captured from the back of the product. When the product is directly below the main recognition camera 15, the mounting rod 17 is vertical and the angle of the mounting rod 17 is 0°, and the image is captured from the top surface of the product. When the product is behind the main recognition camera 15, the angle of the mounting rod 17 is -50°, and the image is captured from the front of the product, thereby improving the recognition effect of product defects.

[0033] The top of the mounting rod 17 is fixedly connected to the outer wall of the limiting shaft 21. Two spring springs 22 are symmetrically sleeved on the outer wall of the limiting shaft 21. Two limiting sleeves 18 are symmetrically fixedly connected to both sides of the inner wall of the mounting base 14. One end of the spring spring 22 is fixedly connected to the limiting shaft 21, and the other end of the spring spring 22 is fixedly connected to the inner wall of the limiting sleeve 18. When adjusting the angle of the mounting rod 17, the limiting shaft 21 drives the spring spring 22. When the angle of the mounting rod 17 is less than -50°, the teeth of the incomplete gear 19 separate from the teeth at the top of the mounting rod 17. At this time, under the drive of the spring spring 22, the mounting rod 17 resets, and the angle of the mounting rod 17 is 50°, so as to identify defects in the next product.

[0034] In one embodiment, two bases 23 are fixedly connected to the bottom of the support frame 11, and a conveyor 31 is provided below the support frame 11. The support frame 11 is mounted on the frame of the conveyor 31 through the bases 23. The support frame 11 can enhance the stability of the detection and identification component 101.

[0035] In operation, this invention works as follows: The product is conveyed via conveyor 31; a servo motor 16 drives a drive shaft 20 to rotate; the drive shaft 20 drives an incomplete gear 19; the incomplete gear 19 drives a mounting rod 17 via its teeth; the mounting rod 17 rotates via a limit shaft 21; and the rotation of the mounting rod 17 drives the main recognition camera 15, thereby allowing adjustment of the angle of the main recognition camera 15. When the product is in front of the main recognition camera 15, the angle of the mounting rod 17 is 50°, allowing image acquisition from behind the product. When directly below, the angle of the mounting rod 17 is 0°, capturing images of the top surface of the product. When the product is behind the main recognition camera 15, the angle of the mounting rod 17 is -50°, capturing images of the front of the product. Simultaneously, in conjunction with the side recognition camera 13, defects can be identified on the top surface and four sides of the product. When the angle of the mounting rod 17 is less than -50°, the teeth of the incomplete gear 19 separate from the teeth at the top of the mounting rod 17. At this time, driven by the spring 22, the mounting rod 17 resets, so as to identify defects in the next product.

[0036] Compared with the prior art, this utility model can acquire images of the top surface and four sides of the product by adjusting the angle and position of the main recognition camera 15 and cooperating with two side recognition cameras 13, thereby ensuring the effectiveness of product defect recognition.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
