Description

Technical Field

[0001] This utility model relates to the field of photoelectric detection equipment, and more specifically, to a small bracket photoelectric detection device. Background Technology

[0002] Photoelectric detection is an indispensable part of industrial automation. Currently, the country is strongly supporting and developing industrial automation and intelligentization, encouraging technological innovation, material innovation, and innovative thinking. Automation and intelligentization are inevitable trends in the future development of the machinery manufacturing industry. Traditional manufacturing production models are gradually becoming inadequate for current production methods, which are not only costly and inefficient but also result in significant resource waste.

[0003] Taking the inspection of small brackets on a product as an example, multiple small brackets are installed on the product using bolts. Manual inspection is required to check for missing, deformed, or incomplete brackets. However, manual inspection can lead to visual fatigue, causing many omissions and compromising accuracy. Furthermore, manual inspection is inefficient and costly. Each person's judgment of defects differs, relying primarily on visual inspection, making it difficult to establish quantifiable quality standards. Utility Model Content

[0006] The lifting drive mechanism drives the photoelectric detection mechanism to switch back and forth between the two sets of fixed bases; the photoelectric detection mechanism includes a detection bracket and a plurality of photoelectric detection sensors mounted on the detection bracket, and the plurality of photoelectric detection sensors correspond one-to-one with the small brackets on the product.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0020] like Figures 1-3 As shown, this utility model provides a small-support photoelectric detection device, including two sets of fixed bases 1 arranged vertically for placing the product 15 to be inspected, a photoelectric detection mechanism 6 disposed outside the fixed bases 1, and a lifting drive mechanism 11 for driving the photoelectric detection mechanism 6 to move up and down. The lifting drive mechanism 11 drives the photoelectric detection mechanism 6 to switch back and forth between the two sets of fixed bases 1.

[0021] In this design, both sets of fixed bases 1, one above the other, can be used to mount the product 15 to be tested. A set of photoelectric detection mechanisms 6 can be driven up and down by a lifting drive mechanism 11, allowing them to switch positions between the two sets of fixed bases 1. When testing the product 15 on the upper fixed base 1, the lifting drive mechanism 11 drives the photoelectric detection mechanism 6 to the upper fixed base 1. The same applies when testing the product 15 on the lower fixed base 1. The lifting mechanism uses an electric guide rail structure or other feasible structures (such as cylinders). This design solves the problem of testing stagnation caused by the disassembly and assembly of the product 15. While one fixed base 1 is disassembling or assembling the product 15, the other fixed base is being tested, achieving alternating testing and thus improving testing efficiency.

[0022] The photoelectric detection mechanism 6 includes a detection bracket 7 and a plurality of photoelectric detection sensors 8 mounted on the detection bracket 7. Each of the photoelectric detection sensors 8 corresponds one-to-one with a small bracket 16 on the product 15. During detection, the photoelectric detection sensors 8 emit a light beam to detect the presence and shape integrity of the small bracket 16 (e.g., the light beam is unobstructed when the bracket is missing, or the reflected signal is abnormal when the bracket is deformed), thus achieving non-contact automatic detection.

[0023] The fixed base 1 is provided with positioning components and fixing components. The positioning components include a positioning block 2 and a positioning shaft 3. The positioning shaft 3 passes through a through hole in the product 15, and the positioning block 2 is located in a groove in the product 15. The fixing components include a drive cylinder 4 and a pressure block 5 rotatably connected to the output end of the drive cylinder 4. The positioning shaft 3 is inserted into the through hole of the product 15, and the positioning block 2 is embedded in the groove. Through the "hole-shaft fit + groove positioning", the product 15 is limited in the X, Y, and Z axes on the fixed base 1, ensuring that the position of the product 15 is fixed during detection and avoiding detection errors caused by displacement. The drive cylinder 4 pushes the pressure block 5 to rotate and press down, using mechanical pressure to press the product 15 firmly onto the fixed base 1, preventing the product 15 from shaking during detection and ensuring the accuracy of the photoelectric sensor detection position.

[0024] Two sets of products 15 are simultaneously fixed on the fixed base 1. Two sets of detection brackets 7 and photoelectric detection sensors 8 are correspondingly arranged, and the two sets of detection brackets 7 are connected by connecting rods 9. Two pressure blocks 5 are symmetrically arranged. Each set of fixed base 1 simultaneously fixes two sets of products 15. With the cooperation of two sets of detection brackets 7 (linked by connecting rods 9), the synchronous detection of two products 15 can be achieved in a single operation, further improving the detection efficiency. The two symmetrical pressure blocks 5 simultaneously press the two products 15, which can achieve the fixation of two products 15 by one fixing component.

[0025] The lifting drive mechanism 11 is fixedly connected to one of the detection brackets, and a guide rod 10 is provided through the other detection bracket 7, which is slidably connected to the guide rod 10. The lifting drive mechanism 11 only needs to drive one set of detection brackets 7 (fixed connection side), and drives the other set of brackets to move synchronously through the connecting rod 9, reducing the number of driving components and lowering costs. The unfixed detection brackets 7 have their movement trajectory restricted by the guide rod 10, ensuring that the two sets of brackets remain parallel when lifting, avoiding misalignment between the photoelectric sensor and the small bracket 16 due to shaking, and improving motion stability.

[0026] The lower fixed base 1 is slidably mounted. A mounting base 12 is located at the bottom of the lower fixed base 1, and a sliding groove 13 is provided on the mounting base 12. A slider 14, connected to the lower fixed base 1, is located within the sliding groove 13. During loading and unloading, the lower fixed base 1 is pulled outwards to offset from the upper fixed base 1. The lower base achieves horizontal pulling through the slider 14 and sliding groove 13 structure. During loading and unloading, it can slide outwards to offset from the upper base, leaving operating space for manual placement of new workpieces or robotic arm grabbing of inspected workpieces, avoiding interference with the upper base currently being inspected. This offset design separates the loading / unloading process from the inspection process, enabling a cyclical flow of "lower loading → base reset → inspection mechanism descent inspection → upper unloading + lower inspection → upper loading," shortening cycle time and adapting to automated production lines.

[0027] The photoelectric detection device of the small bracket 16 in this application can accurately position and firmly fix the product 15 through the cooperation of positioning and fixing parts, ensuring the accuracy of detection. The two sets of fixed bases 1 and the two sets of detection brackets 7 are linked together, and the lifting drive mechanism 11 conducts alternating detection, which greatly improves the detection efficiency and realizes "feeding and detection" in parallel. The sliding design of the lower fixed base 1 facilitates loading and unloading and is suitable for assembly line operation. The photoelectric detection sensor 8 corresponds one-to-one with the small bracket 16, with high detection accuracy and quantifiable results, avoiding manual omissions and judgment differences. The structure is stable and highly automated, reducing manual intervention and labor intensity, reducing labor costs, and is suitable for mass production, which is in line with the development trend of industrial automation and intelligence.
