Description

Technical Field

[0001] This utility model relates to the field of cleanroom robot suitability testing, and in particular to a cleanroom robot suitability simulation field testing device. Background Technology

[0002] With the continuous development of science and technology, high-tech industries and intelligent manufacturing industries have become an important force in industrial development, and these two industries will continue to maintain a high-speed growth trend in the future. Robots, as a microcosm of the development of high-tech and intelligent manufacturing industries, integrate knowledge from multiple fields such as mechanics, electronics, computers, and control, and are widely used in manufacturing, automotive, electronics, logistics, and medical industries. Due to the stringent requirements of the production environment in these industries, a high degree of cleanliness is needed to meet the requirements of reliability, high performance, and high-quality production processes. Because of their complex structure and numerous components, robots are prone to generating tiny particles during production, which can be released into the clean area, causing environmental contamination and affecting production quality. Therefore, before robots are put into clean area production, their cleanliness must be guaranteed. They must pass a suitability simulation field test to meet specified requirements before being put into actual production applications. Since there is currently no evaluation method for the suitability of cleanroom robots in China, the research on cleanroom robot suitability simulation field test devices is particularly important. Utility Model Content

[0003] The purpose of this invention is to provide a field testing device for the applicability of cleanroom robots that can simulate the actual working state of cleanroom robots and record cleanliness, so as to facilitate the evaluation of the applicability of cleanroom robots on the market.

[0004] The cleanroom robot applicability simulation field testing device of this utility model includes a simulation field chamber for placing the cleanroom robot to be tested. The simulation field chamber is equipped with an air conditioning purification system that is connected to the external environment to purify the simulation field chamber. An ultraviolet disinfection lamp is installed in the simulation field chamber. An experimental operation room is set around the simulation field chamber. A clean air shower is set between the experimental operation room and the external environment to enter the experimental operation room. A sampling tube that can extend from the experimental operation room into the simulation field chamber to collect dust particles is set on the outside of the simulation field chamber. The sampling tube is connected to a particle counter that records the concentration of dust particles in the simulation field chamber before and after cleaning by the cleanroom robot.

[0005] The cleanroom robot suitability simulation field testing device of this utility model places the cleanroom robot under test into a simulated field chamber. The simulated field chamber is purified and sterilized using an air conditioning purification system and ultraviolet disinfection lamps. Then, outside the test operation room, a particle counter is used to record the dust particle concentration in the simulated field chamber before the cleanroom robot is started. After the cleanroom robot is started, it cleans the simulated field chamber. The dust particle concentration after cleaning is recorded outside the test operation room using a particle counter and a sampling tube. By comparing the dust particle concentration before and after cleaning, the cleanliness of the cleanroom robot can be simulated under its actual working state, facilitating the evaluation of its suitability for the market. Furthermore, because a clean air shower is provided between the test operation room and the external environment, preliminary cleaning can be performed on the operators and the cleanroom robot before testing upon entering the test operation room, thereby improving the accuracy of the simulated field test data and making the evaluation of the suitability of the cleanroom robot on the market more accurate.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In this utility model, it should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0019] A field testing device for simulating the applicability of cleanroom robots, such as Figure 1 - Figure 2 As shown, the system includes a simulated field chamber 1 for placing the cleanroom robot under test. The simulated field chamber is equipped with an air conditioning purification system 2 that is connected to the external environment to purify the simulated field chamber. An ultraviolet disinfection lamp 3 is installed inside the simulated field chamber. An experimental operation room 4 is set up around the simulated field chamber. A clean air shower room 5 is set up between the experimental operation room and the external environment to allow entry into the experimental operation room. A sampling tube 6 is set up on the outside of the simulated field chamber, which can extend from the experimental operation room into the simulated field chamber to collect dust particles. The sampling tube is connected to a particle counter 7 that records the concentration of dust particles before and after cleaning by the cleanroom robot in the simulated field chamber.

[0020] The simulated field chamber is used to simulate the clean area where the cleanroom robot operates. Its main structure is made of special tempered glass, eliminating background particle release and allowing real-time direct visual observation of the robot's operating status. This enables smooth control of the robot's actions, avoiding the inconvenience of testing with other materials such as cement or stainless steel. The simulated field chamber measures 7.0m × 4.0m × 3.0m. A router is installed inside the simulated field chamber, and its Wi-Fi signal is connected to the robot under test. The robot is controlled from the test room via a network connection to the router in the simulated field chamber. The particle counter is a laser dust particle counter, based on the principle of laser scattering, with six channels: 0.1 μm, 0.2 μm, 0.3 μm, 0.5 μm, 1.0 μm, and 5.0 μm. This allows for real-time recording of dust particle concentration and enables real-time data transmission to a display terminal via network connection. The particle counter can be placed at the required test location outside the simulated work area according to experimental requirements. Its height can be adjusted via a retractable sampling frame, allowing for particle concentration display outside the simulated work area and reducing interference from irrelevant items on particle release. The testing equipment in the experimental operation room allows sampling via sampling tubes set up in the simulated work area and personnel operating the particle counter. The operating status of the cleanroom robot can be directly observed through transparent glass. The cleanroom air shower is equipped with electronic interlock control. After operators and the cleanroom robot enter, the shower door is closed via an infrared sensor, followed by preliminary cleaning of both personnel and the cleanroom robot. This improves the accuracy of simulated field test data and makes the evaluation of the applicability of cleanroom robots on the market more accurate. Furthermore, the cleanroom air shower uses a two-stage filtration system with pre-filters and high-efficiency filters. The low-resistance, plateless high-efficiency filters achieve a filtration efficiency of 99.99%, ensuring a high level of purification. It is equipped with multi-angle adjustable nozzles made of stainless steel and a high-volume, low-noise fan with a dual-volute external rotor. The air velocity at the nozzle outlet is ≥25m / s, further improving the accuracy of simulated field test data and making the evaluation of the applicability of cleanroom robots on the market more accurate.

[0021] A sealed door 8, connecting to the test operation room, is installed in the simulated field work chamber. The sealed door is equipped with a door lock device 9. The sealed door 8 allows operators to place the cleanroom robot into the simulated field work chamber. The door is fitted with sealing strips and has a triple lock device to ensure the airtightness of the simulated field work chamber and to guarantee that the relative pressure difference between the inside and outside meets the experimental requirements for particle counter sampling through the sampling tube. An operating glove 10, extending from the test operation room into the simulated field work chamber, is installed in the simulated field work chamber. This glove allows for adjusting the placement of instruments and equipment and operating related switches within the sealed simulated field work chamber, further improving the accuracy of the simulated field test data and enabling more accurate evaluation of the applicability of cleanroom robots on the market.

[0022] A transfer window 11 is installed in the simulated field work area to transfer items from the test operation room to the simulated field work area. A sealed transfer window door is installed on the transfer window. The transfer window allows for the transfer of samples and test items between the test operation room and the simulated field work area, reducing the number of times the simulated field work area door is opened, ensuring the cleanliness of the test area, further improving the accuracy of simulated field test data, and making more accurate evaluations of the applicability of cleanroom robots on the market.

[0023] Two agitating fans 12 are installed on the ceiling of the simulated field chamber to agitate the gas inside, resulting in more accurate sampling and improved accuracy of the simulated field test data. This allows for a more accurate evaluation of the applicability of the cleanroom robot to the market. Additionally, lighting 13 is installed on the ceiling of the simulated field chamber to facilitate observation of the cleanroom robot's operating status.

[0024] By installing a temperature and humidity monitor 14 in the simulated field workshop to monitor the temperature and humidity inside the simulated field workshop, the temperature and humidity inside the simulated field workshop can be effectively monitored, further improving the accuracy of the simulated field test data.

[0025] The sampling system includes a sampling hose, one end of which is connected to a sampling tube extending into the simulated work chamber, and the other end is connected to a particle counter. Eight sampling tubes are installed, positioned 1.0 m from each corner on each axis within the simulated work chamber, and 1.0 m above the nearest surface, enabling effective omnidirectional dynamic monitoring of particle concentration within the simulated work chamber. Each sampling tube is equipped with a stainless steel straight-through ball valve to ensure airtightness of the simulated work area and can be used for pressure differential and air monitoring after the test chamber door is closed.

[0026] The air conditioning and purification system 2 includes an air conditioning unit 21 and an air purifier 22 installed in the simulated field work area. One end of the air conditioning unit is connected to the return air vent 23 in the simulated field work area via a duct, and the other end is connected to the air purifier via a duct. The air purifier is connected to the supply air vent 24 in the simulated field work area via a duct. The fresh air outlet 25 of the air conditioning unit is connected to the interior of the simulated field work area. The air outlets of the air conditioning and purification system are equipped with airtight dampers to ensure that the relative pressure difference in the simulated field work area meets the test requirements when closed.

[0027] The above embodiments are only used to illustrate the detailed solution of this utility model. This utility model is not limited to the above detailed solution, that is, it does not mean that this utility model must rely on the above detailed solution to be implemented. Those skilled in the art should understand that any improvement to this utility model, equivalent substitution of the raw materials of this utility model product, addition of auxiliary components, selection of specific methods, etc., all fall within the protection scope and disclosure scope of this utility model.
