Description

Technical Field

[0001] This utility model belongs to the field of visual inspection equipment technology, specifically relating to an equipment for visual inspection of 2D and 3D geometric quantities of precision parts. Background Technology

[0002] Electronic devices include mobile phones, tablets, and other similar devices. These devices typically include a casing, which comes in various shapes and sizes. While electronic device casings are usually cast, with the development of technology, 3D printing has become a molding method. Therefore, some electronic device casings are also formed using 3D printing. Most 3D-printed electronic device casings require corresponding testing to check for defects on their internal surfaces.

[0003] In the existing technology, aluminum alloy plates for manufacturing electronic equipment are inspected manually. This inspection method requires manual operation, resulting in high labor intensity for operators and low inspection accuracy. Utility Model Content

[0004] This invention provides equipment for visual inspection of 2D and 3D geometric quantities of precision parts, aiming to solve the problems of low inspection accuracy and high labor intensity of operators in the production of aluminum alloy plates for electronic equipment in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An apparatus for visual inspection of 2D and 3D geometric quantities of precision parts includes a feeding assembly and an inspection assembly, wherein the feeding assembly feeds materials to the inspection assembly;

[0007] The detection assembly includes a frame, on which an annular conveyor is mounted. The frame is also equipped with a first 3D flatness detector, a second 3D flatness detector, and a 2D size detector. The annular conveyor carries the material to be detected through the first 3D flatness detector, the second 3D flatness detector, and the 2D size detector in sequence.

[0008] The frame is also equipped with a discharge component. After the material has been detected by the 2D size detector, it enters the discharge component and is output by the discharge component.

[0009] A further improved solution: Both the feeding component and the discharging component are belt conveyors, and the material conveying direction of the feeding component is perpendicular to the material conveying direction of the discharging component.

[0010] Based on the above technical solution: the material conveying direction of the feeding component is perpendicular to the material conveying direction of the discharging component. This vertical layout allows the feeding and discharging processes to be efficiently superimposed in space, rather than simply arranged linearly. This design significantly saves the floor space of the production line, enabling the entire testing device to achieve greater production efficiency within a limited space. Another advantage of the vertical layout is that it makes the turning and positioning of materials during the transmission process simpler and clearer. The material enters the testing area from the feeding component, is tested, and then vertically output by the discharging component. This process not only reduces unnecessary movement and waiting time of the material during transmission but also makes the entire testing process smoother and more efficient. For operators, the vertical layout of the feeding and discharging components allows them to more intuitively monitor the status of the material during the testing process. At the same time, due to the improved space utilization, the operator's work area is also optimized accordingly, improving their comfort and efficiency during operation.

[0011] A further improved solution: the first 3D flatness detector, the second 3D flatness detector, and the 2D size detector are all non-contact visual detectors.

[0012] Based on the above technical solutions, non-contact visual detectors utilize advanced laser or machine vision technology to achieve high-precision measurement of the surface morphology of aluminum alloy plates, with accuracy ranging from nanometers to micrometers. By avoiding the physical damage and force effects that can occur with traditional contact measurements, non-contact inspection can more accurately reflect the true morphology of the aluminum alloy plate and reduce measurement errors. Non-contact inspection does not cause any physical damage to the aluminum alloy plate, making it suitable for the inspection needs of high-precision, high-value products. Due to its non-destructive nature, this inspection method can be applied to the inspection of aluminum alloy plates of various materials and shapes, improving the versatility and flexibility of the inspection.

[0013] A further improved solution: The annular conveyor includes an annular conveyor belt and a drive mechanism for driving the annular conveyor belt to rotate. The drive mechanism includes a driving wheel and a driven wheel. The annular conveyor belt is disposed on the driving wheel and the driven wheel. A motor for driving the driving wheel to rotate is also disposed on the frame.

[0014] Based on the above technical solution, the design of the circular conveyor belt enables continuous closed-loop material transfer between the driving and driven wheels without interruption or reloading, thereby improving transfer efficiency. Since the circular conveyor belt is seamless, it avoids transfer problems caused by unevenness or insufficient strength at joints, ensuring the stability and safety of materials during transport.

[0015] A further improved solution: There are three driven wheels, all of which are rotatably connected to the frame. The driving wheel and the driven wheels make the shape of the annular conveyor belt rectangular.

[0016] Based on the above technical solution, compared to traditional circular or elliptical layouts, rectangular layouts can utilize space more effectively. In a rectangular layout, all parts of the circular conveyor belt fit tightly onto the driving and driven pulleys, eliminating unnecessary gaps or waste. Because the rectangular layout is more compact, the entire circular conveyor occupies a relatively small floor area. This is especially important for production environments with limited space, maximizing the use of existing space and improving production efficiency.

[0017] A further improved solution: There are two discharge components, which are arranged in parallel. The frame is also equipped with two unloading robots, which correspond one-to-one with the discharge components.

[0018] Based on the above technical solution: the two discharge components are arranged in parallel, making full use of the frame width and resulting in a more compact layout. This design not only saves space but also facilitates subsequent operation and maintenance. The parallel discharge components can simultaneously process two different specifications of materials. This means that during production, materials of different specifications can be effectively isolated and classified, avoiding confusion and errors.

[0019] A further improved solution: the upper surfaces of the two discharge components are flush, and the two discharge components output the detected material in the same direction.

[0020] Based on the above technical solution: the flush upper surfaces of the two discharge components mean that the material output from them will be at the same horizontal level. This facilitates subsequent material handling, sorting, or packaging processes, as operators or automated equipment do not need to adjust or switch between different heights. The flush upper surfaces simplify the transition process of material from the detection component to the discharge component. Material can smoothly enter the discharge component from the detection component, reducing the risk of jamming or falling due to height differences.

[0021] A further improved solution: A feeding component is provided between the feeding component and the detection component. The feeding component includes a guide rail mounted on the frame, a slide is provided on the guide rail, and a feeding robot is provided on the slide. The feeding robot conveys the material of the feeding component to the annular conveyor.

[0022] Based on the above technical solution, the feeding assembly, through the design of guide rails and carriages, achieves continuous and automated material transfer. This avoids the tedious and time-consuming manual handling, significantly improving production efficiency. The feeding robot can precisely pick up materials from the feeding assembly and place them onto the circular conveyor. This precision ensures the stability and consistency of materials during the transfer process, reducing errors or malfunctions caused by positional deviations.

[0023] A further improvement: The frame is equipped with a driver that drives the carriage to reciprocate between the feeding assembly and the annular conveyor.

[0024] Based on the above technical solution: the drive automatically propels the carriage, reducing the number of times materials need to be manually handled, thereby reducing the labor intensity of operators. The automated transport system can complete material handling tasks more quickly, shortening the production cycle and improving overall production efficiency.

[0025] A further improved solution: the actuator is a hydraulic cylinder; or, the actuator is a pneumatic cylinder.

[0026] Based on the above technical solutions: Hydraulic cylinders can output greater power, making them suitable for applications requiring heavy loads or strong thrust. Their pressure range is typically much higher than air pressure, thus meeting the demands of operations requiring high force. Due to the incompressibility of hydraulic fluid, hydraulic cylinders can achieve high-precision position and speed control. This gives them a significant advantage in applications requiring precise control of motion trajectory and force. Pneumatic cylinders have a relatively simple structure, are easy to install and maintain. Their working principle is based on changes in air pressure, therefore eliminating the need for a complex hydraulic circulation system. Pneumatic and hydraulic cylinders are interchangeable, and their actuators are easy to maintain.

[0027] The beneficial effects of this utility model are as follows:

[0028] This invention achieves high-precision detection of the flatness of aluminum alloy plate surfaces by using a first 3D flatness detector and a second 3D flatness detector. This non-contact detection method avoids potential damage from traditional contact measurements while improving accuracy and efficiency. The 3D flatness detector constructs a three-dimensional model of the aluminum alloy plate surface and accurately calculates the flatness deviation by comparing it with parameters of a standard plane, thus meeting the high-precision requirements of electronic devices. The 2D dimension detector is used to detect the dimensional accuracy of the aluminum alloy plate, ensuring that the product meets design requirements. Through high-precision image capture and processing technology, the dimensional information of the aluminum alloy plate can be accurately identified, improving the accuracy and reliability of the detection.

[0029] This device automates the entire process from feeding and testing to discharging. Operators simply place the aluminum alloy sheet to be inspected into the feeding assembly, and the device automatically completes the subsequent inspection and discharging, significantly reducing operator workload. Utilizing advanced vision inspection technology, the device achieves rapid and accurate inspection. This helps shorten production cycles and improve production efficiency.

[0037] The detection component 2 includes a frame 3, on which an annular conveyor 7 is provided.

[0038] The frame 3 is also equipped with a discharge component 8. After the material is detected by the 2D size detector 6, it enters the discharge component 8 and is output by the discharge component 8.

[0039] Wherein: both the feeding assembly 1 and the discharging assembly 8 are belt conveyors, and the material conveying direction of the feeding assembly 1 is perpendicular to the material conveying direction of the discharging assembly 8. A belt conveyor typically includes a driving roller and a driven roller, with a conveyor belt positioned between the driving roller and the driven roller. The driving roller can be driven by a motor.

[0040] Among them, the first 3D flatness detector 4, the second 3D flatness detector 5, and the 2D size detector 6 are all non-contact visual detectors. When higher detection accuracy is required, more non-contact visual detectors can be set.

[0041] Specifically: The annular conveyor 7 includes an annular conveyor belt and a drive mechanism for driving the annular conveyor belt to rotate.

[0042] Specifically: There are two discharge components 8, arranged in parallel. The frame 3 is also equipped with two unloading robots 11, each corresponding to one of the discharge components 8. The upper surfaces of the two discharge components 8 are flush, and both discharge components 8 output the inspected material in the same direction. For materials of different specifications, for example, qualified materials can be placed on one discharge component 8, while unqualified materials can be placed on the other discharge component 8.

[0043] A feeding assembly is provided between the feeding component 1 and the detection component 2. The feeding assembly includes a guide rail mounted on the frame 3, a slide rail on the guide rail, and a feeding robot 12 mounted on the slide rail. The feeding robot 12 conveys the material from the feeding assembly to the annular conveyor 7. The frame 3 is equipped with a driver that drives the slide rail to reciprocate between the feeding assembly and the annular conveyor 7. The driver is a hydraulic cylinder; alternatively, it is a pneumatic cylinder. The feeding robot 12 can use a suction cup to pick up the material. Alternatively, the feeding robot 12 can use other mechanisms capable of gripping materials.

[0044] The working principle of this embodiment:

[0045] The operator manually places the material onto the feeding assembly 1, which then feeds the aluminum alloy plate to be tested into the testing assembly 2. This step is the starting point of the testing process, ensuring that the testing device can continuously and stably acquire the material to be tested.

[0046] The inspection component 2 is the core part of the device, including a frame 3, a ring conveyor 7, a first 3D flatness detector 4, a second 3D flatness detector 5, and a 2D dimension detector 6. Driven by the ring conveyor 7, the aluminum alloy plate passes through these detectors sequentially, completing a comprehensive inspection of its flatness and dimensions.

[0047] After inspection, qualified aluminum alloy sheets enter the discharge assembly 8, which outputs them, completing the inspection of the aluminum alloy sheets. Unqualified aluminum alloy sheets can be recycled and reprocessed or scrapped.
