Description

Technical Field

[0001] This application relates to the technical field of optical inspection equipment, and in particular to an automatic optical inspection equipment with a novel air supply mode. Background Technology

[0002] In the application of automated optical inspection (AOI) equipment, existing inspection equipment typically has high requirements for ambient temperature, humidity, and air quality. For example, the inspection equipment needs to operate in a separate air-conditioned room to ensure that the temperature is below 26°C and the humidity is below 70%. However, in actual production environments, equipment is often placed in high-temperature, high-dust workshops, such as drilling workshops or near tunnel ovens. This environment causes dust to accumulate inside the equipment, affecting the performance of key components such as light sources, lenses, and rollers, thereby reducing inspection accuracy and equipment stability. In addition, building a separate air-conditioned room is not only costly but also inconvenient for the production process.

[0003] Existing AOI inspection equipment typically relies directly on air conditioning systems to provide cooling air, but this method cannot effectively filter dust or create a positive pressure environment inside the equipment to prevent external pollutants from entering.

[0004] To overcome the shortcomings of existing technologies, this application proposes a novel automatic optical inspection device with a new air supply mode, which aims to achieve active air supply and air filtration to meet the working environment requirements of the automatic optical inspection device and reduce the impact of dust on the internal components of the device. Utility Model Content

[0005] The purpose of this application is to provide a novel automatic optical inspection device with a new air supply mode to solve the aforementioned technical problems existing in the prior art.

[0006] This application provides a novel automatic optical inspection device for air supply modes, the automatic optical inspection device comprising:

[0007] The equipment body has at least one air outlet on its top.

[0008] The air supply system is located on the top of the equipment body and is connected to the air outlet through an air supply duct. The air supply system delivers air at a temperature lower than the preset temperature to the interior of the equipment body. An FFU fan filter unit is installed in the air supply duct to filter the air delivered by the air supply system to reduce the entry of external dust into the interior of the equipment body. The preset temperature is 26 degrees Celsius.

[0009] Furthermore, the interior of the equipment body is a positive pressure environment, maintaining the internal air pressure of the equipment body higher than the external air pressure.

[0010] Furthermore, an exhaust vent is provided at the bottom or side of the equipment body to expel hot or polluted air from inside the equipment body.

[0011] Furthermore, the equipment body is also equipped with a pressure monitoring and regulation system. The pressure monitoring and regulation system is used to detect the internal air pressure of the equipment body and adjust the internal air pressure of the equipment body by adjusting the air supply of the air supply system and the air flow of the exhaust port.

[0012] Furthermore, the pressure monitoring and regulation system includes:

[0013] Pressure sensor used to monitor the internal air pressure of the device body in real time;

[0014] The pressure regulating device automatically adjusts the air input of the air supply system and / or the air flow of the exhaust vent based on feedback from the pressure sensor, ensuring that the internal air pressure of the equipment body is always higher than that of the external environment.

[0015] Furthermore, the FFU fan filter unit has a replaceable structure.

[0016] Furthermore, there are four air outlets, which are arranged at intervals on the top of the equipment body. The air supply duct is equipped with four connectors, which are connected to the air outlets.

[0017] The FFU fan filter unit includes four FFU fans, which are respectively installed at the end of the air supply duct with the interface.

[0018] Furthermore, the air supply system also includes a temperature and humidity control system, which is used to regulate the temperature and humidity of the air entering the equipment body to ensure that the operating environment of the automatic optical inspection equipment is below 26°C and the humidity is below 70%.

[0019] Furthermore, the device itself is equipped with a detection mechanism, which includes a light source, a lens, and a camera. The light source and lens are used to perform optical imaging of the object being detected, and the camera is used to capture images and perform image analysis.

[0020] Furthermore, the equipment body is also equipped with a dust monitoring device, which is used to monitor the dust concentration inside the equipment body in real time, and trigger an alarm or automatically start the air supply system when the dust concentration exceeds a preset threshold.

[0021] Unlike existing technologies, this application incorporates an air supply duct connecting the equipment body and the air supply system. This allows the air supply system to deliver air at a temperature below a preset value (below 26 degrees Celsius) into the equipment body, meeting the operating temperature requirements of automated optical inspection equipment. Furthermore, this application includes an FFU (Fan Filter Unit) within the air supply duct, filtering the air supplied by the air supply system. This effectively reduces the entry of external dust into the equipment body, minimizing its impact on internal components.

[0027] To enable those skilled in the art to better understand the technical solutions of this application, the novel automatic optical inspection device for air supply modes provided in this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It is understood that the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0029] Since existing AOI inspection equipment usually relies directly on air conditioning systems to provide cooling air, this method cannot effectively filter dust or create a positive pressure environment inside the equipment to prevent external pollutants from entering. This application provides an automatic optical inspection equipment with a novel air supply mode that can actively supply air and filter air to meet the working environment requirements of the automatic optical inspection equipment and reduce the impact of dust on the internal components of the equipment.

[0030] Please see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the automatic optical inspection device with a novel air supply mode according to this application. The automatic optical inspection device 1 with a novel air supply mode according to this application includes a device body 10 and an air supply system 20, wherein the device body 10 is provided with an air outlet 11, and the air supply system 20 is connected to the air outlet 11 through an air supply pipe 21 to connect the air supply system 20 with the interior of the device body 10.

[0031] Specifically, at least one air outlet 11 is provided on the top of the device body 10, and an air supply system 20 is provided on the top of the device body 10 and connected to the air outlet 11 through an air supply duct 21, so that the air supply system 20 delivers air with a temperature lower than the preset temperature to the interior of the device body 10. In this embodiment, the preset temperature is 26 degrees Celsius, and the air with a temperature lower than the preset temperature is cold air with a temperature lower than 26 degrees Celsius, which meets the operating temperature requirements of the automatic optical inspection device 1.

[0032] Optionally, in this embodiment, the device body 10 is installed on the indoor floor, and the air supply system 20 is installed on the ceiling, which does not occupy indoor space and can utilize existing air supply systems.

[0033] An FFU fan filter unit 23 is installed in the air supply duct 21. The FFU fan filter unit 23 is used to filter the air supplied by the air supply system 20 to reduce the entry of external dust into the interior of the equipment body 10.

[0034] Furthermore, in this embodiment, the interior of the device body 10 is a positive pressure environment, maintaining an internal air pressure higher than the external air pressure. This embodiment uses an air supply system 20 to deliver air into the device body 10, maintaining a positive pressure environment. This prevents dust and particles from entering, avoiding interference with imaging quality and causing detection errors. It also protects optical components (such as lenses and sensors) from contamination. Secondly, the positive pressure environment helps reduce airflow turbulence within the device body 10, further improving detection accuracy. Simultaneously, the positive pressure environment prevents external moisture from entering, avoiding condensation or dampness on the surface of optical components, thereby extending the device's lifespan.

[0035] Optionally, the FFU fan filter unit 23 in this embodiment has a replaceable structure, which facilitates regular maintenance and replacement.

[0036] like Figure 1 As shown, in this embodiment, there are four air outlets 11. The four air outlets 11 are arranged at intervals on the top of the equipment body 10. The air supply duct is provided with four connection ports 22, and the connection ports 22 are connected to the air outlets 11 respectively.

[0037] The FFU fan filter unit 23 in this embodiment includes four FFU fans 231, which are respectively installed at one end of the air supply duct where the interface 22 is provided.

[0038] Optionally, in other embodiments, the number of air outlets 11 can be multiple, as long as the number of air outlets 11 is consistent with the number of interfaces 22, and each air supply branch is equipped with an FFU fan 231.

[0039] Alternatively, the air outlet 11 can be located not only on the top of the equipment body 10, but also on the side wall of the equipment body 10, as long as the length of the air supply duct 21 is sufficient to extend to the air outlet 11 furthest from the air outlet of the air supply system 20.

[0040] Optionally, the bottom or side of the device body 10 in this embodiment is provided with an exhaust vent (not shown in the figure), which is used to exhaust hot air or polluted air inside the device body 10.

[0041] Optionally, the device body 10 of this embodiment may be equipped with a pressure monitoring and regulation system (not shown in the figure). The pressure monitoring and regulation system is used to detect the internal air pressure of the device body 10 and adjust the internal air pressure of the device body 10 by adjusting the air supply of the air supply system 20 and the air flow of the exhaust port.

[0042] Specifically, the pressure monitoring and regulation system includes a pressure sensor and a pressure regulating device. The pressure sensor is used to monitor the internal air pressure of the equipment body 10 in real time. The pressure regulating device automatically adjusts the air input of the air supply system 20 and / or the air flow of the exhaust port according to the feedback from the pressure sensor, so as to ensure that the internal air pressure of the equipment body 10 is always higher than that of the external environment.

[0043] Optionally, the air supply system 20 in this embodiment may include a temperature and humidity control system (not shown). The temperature and humidity control system is used to adjust the temperature and humidity of the air entering the device body 10 to ensure that the temperature of the operating environment of the automatic optical detection equipment is below 26°C and the humidity is below 70%.

[0044] Optionally, the temperature and humidity control system can also be installed inside the equipment body 10 to directly monitor the air temperature and humidity inside the equipment body 10, and adjust the air temperature and humidity by adjusting the air supply of the air supply system 20 and the air flow of the exhaust vent.

[0045] Optionally, the device body 10 of this embodiment may be provided with a detection mechanism (not shown in the figure). The detection mechanism includes a light source, a lens and a camera. The light source and lens are used to perform optical imaging on the object to be detected, and the camera is used to capture images and perform image analysis.

[0046] Optionally, the device body 10 of this embodiment may be equipped with a dust monitoring device (not shown in the figure). The dust monitoring device is used to monitor the dust concentration inside the device body 10 in real time, and trigger an alarm or automatically start the air supply system 20 when the dust concentration exceeds a preset threshold.

[0047] Optionally, a control panel (not shown) may be provided on the outside of the device body 10 in this embodiment. The control panel is used to control the operation of the air supply system 20, the detection mechanism and other auxiliary equipment, so that the operator can monitor the internal situation of the device body 10 through the control panel and make real-time adjustments.

[0048] Optionally, the bottom of the device body 10 in this embodiment is provided with a moving mechanism (not shown in the figure). The moving mechanism includes casters and a support frame. The casters are used to move the device body 10, and the support frame is used to fix and stabilize the device body 10.

[0049] This application provides an air supply duct 21 connecting the equipment body 10 and the air supply system 20, allowing the air supply system 20 to deliver air at a temperature lower than a preset value (i.e., cold air below 26 degrees Celsius) to the interior of the equipment body 10 via the air supply duct 21, thus meeting the operating temperature requirements of the automatic optical inspection equipment. Furthermore, this application includes an FFU (Fan Filter Unit) 23, composed of multiple FFU fans 231, within the air supply duct 21. This ensures that every stream of air delivered by the air supply system 20 is filtered by the FFU 23, effectively reducing the entry of external dust into the equipment body and minimizing its impact on internal components. The cold air delivered by the air supply system 20 to the equipment body 10 helps maintain a positive pressure environment inside the equipment body 10, ensuring a clean, stable, and controllable testing environment, and effectively improving the accuracy and reliability of the automatic optical inspection equipment 1's test results.
