Detailed Description

The full-automatic oxygen and nitrogen analysis system consists of a HORIBA MEGA920 oxygen and nitrogen analyzer and a YAMAHA robot and a series of control and operation units. The whole system is supported by an aluminum alloy frame, wherein the analyzer and the manipulator are positioned at the upper part of the frame and are isolated by a totally-enclosed safety fence, and a control cabinet of the system is arranged at the lower part of the frame. When the '408' alarm item appears, the HORIBA MEGA920 oxygen and nitrogen analyzer can still normally analyze and work, so that the alarm item is judged to be particularly called as being caused by the failure of the Jacha robot. The type of the yamaha robot is T6L06BK-400 (T6L represents the type of a robot host, 06 represents the guide distance designated as 6mm, BK represents the braking with the brake, 400 represents the effective stroke of 400mm, the mark is shown by yamaha engine Co., ltd.), the production serial number is 216V6FBF002, the production time is 2021.6, and the production place is Japanese. The robot is a T-shaped frameless one-axis robot, and is matched with an XYZ orthogonal motion guide rail, a TS-X type positioner and an RCX-340 controller. And wherein the operating environment temperature of the RCX-340 controller is between 0℃and 40 ℃. The alarm item with the alarm number of "408 Fauly Robot Control" frequently appears in any analysis mode (manual mode, cuvette mode, automatic mode and full-automatic mode) when the temperature is too high, the transliteration is that "the robot control (controller) is wrong", and the alarm item appears regardless of time and whether the analysis system is in standby or running, that is, the fault alarm can occur anytime and anywhere.

Failure cause:

1. the time period from the system installation to the non-generation of the '408' alarm is 2021.11 to 2022.6, the time period is autumn, winter and spring, and the outdoor temperature of the time period is insufficient to influence the upper limit of the temperature alarm of the robot controller. After 6 months, nanjing, one of the four stoves, is gradually midsummer, and the indoor temperature is naturally affected as the outdoor temperature is continuously increased.

2. The RCX-340 controller of the robot is not placed outside in an empty way, but is placed in a metal cabinet, the periphery of the controller is sealed, only a 7cm multiplied by 8cm louver opening on the side face is used for heat dissipation, and a sponge dust screen is also coated on the window. And the metal cabinet is positioned at the bottommost part of the whole full-automatic system, and the upper space of the metal cabinet is only about 10cm, which is not beneficial to heat dissipation.

3. The laboratory has three doors, and is normally closed at ordinary times to ensure that the temperature and the humidity of the laboratory accord with national standards, and the difference between indoor and outdoor temperature and humidity causes the difference between air pressure inside and outside the laboratory, thereby causing the indoor air to be difficult to flow. According to the design drawing requirements of the whole laboratory, the analysis system is positioned at the wall root, all equipment of the system are concentrated together, and the circuit gas paths are interwoven, so that a relatively independent, closed and space-complicated working environment is formed, besides, the heat dissipation capacity of the instrument is high, the surrounding air mobility is poor, and other instruments and equipment are arranged beside the instrument, so that the temperature of the working environment of the controller is easily increased, and an alarm is generated.

4. The LED screen on the controller is found to display an alarm number E22807 by disassembling the control cabinet of the yamaha robot, and the number is just an overload alarm signal of the working environment temperature of the controller by inquiring the official network of the yamaha engine, so that the system '408' alarm is proved to be caused by the increase of the working environment temperature of the manipulator controller.

Based on the above situation, we propose the following two embodiments, through the improvement to the heat dissipation design of the robot control cabinet, thoroughly solve the problem of the manipulator (408 Fauly Robot Control) of the HORIBA MEGA920 full-automatic oxygen and nitrogen analysis system caused by the too high temperature, so as to ensure the smooth operation of the full-automatic sample analysis system in front of the steelmaking furnace.

As shown in fig. 5, two opposite sides of the blade 5 are staggered to form semi-cylindrical air inducing grooves 51 from an air inlet end to an air exhaust end, air flow entering the cabinet body 1 can be divided into multiple strands through the blade 5 and the air inducing grooves 51 and circulate obliquely upwards, a plurality of diversion grooves 52 penetrate through the middle part of the blade 5, the diversion effect is achieved, the high-efficiency discharge of hot air located on the upper layer in the cabinet body 1 is facilitated, a good heat dissipation effect is achieved, and a first mounting hole 54 for mounting the cabinet body 1 to the first mounting opening 2 is formed in the frame body 1.

As shown in fig. 5 and 6, the air guiding grooves 51 at two ends of the blade 5 are all provided with 3 diversion grooves 53 to the outside for diverting the air flow to the inner wall direction of the cabinet 1, so that part of the air flow passing through the blade 5 can be diverted to the inner wall of the cabinet 1, and the heat dissipation in the cabinet 1 is more complete.

Example 2

Unlike embodiment 1, referring to fig. 2, in this embodiment, the first mounting port 2 of the robotically controlled cabinet is lower than the second mounting port 3, and the lower first mounting port 2 can be used for air intake, and the higher second mounting port 3 can be used for air exhaust and fan-out, so that the heat of the upper layer in the cabinet body 1 can be more quickly and efficiently discharged through air circulation, and the cabinet body 1 is further provided with second mounting holes for mounting the exhaust fan 6, which are respectively located at four corners of the second mounting port 3.
