[0002] The module EOL test completion notification device is part of the test system. It is used to convey key information to operators or automated systems before the EOL test ends through sound and light signals, screen pop-ups, data feedback, etc., such as test progress, abnormal alarms, and result confirmation.
[0003] During existing hydraulic control module EOL testing, operators need to monitor multiple devices simultaneously. Due to the lack of effective prompts at the end of the test, operators find it difficult to respond in a timely manner, leading to increased equipment standby time and affecting the efficiency of production plan execution. Existing technologies typically rely on manual observation or simple buzzer prompts, which suffer from response delays and poor warning effects.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] Reference Figures 1-3 This invention provides a module EOL (End of Operation) test warning device, which includes a pneumatic-electric changeover switch 1, an audible and visual warning light, and a mounting bracket 3. The pneumatic-electric changeover switch 1 is an SMC AS2201F-04-08A type (G1 / 4 threaded interface), with a normally closed contact withstand voltage rating of 24VDC / 2A, and is installed at the end of the air source output pipe of the valve island. The mounting bracket 3 is made of 6061-T6 aluminum alloy profile.
[0025] The pneumatic-electric conversion switch 1 is connected in series to the gas source input pipeline of the EOL valve island via a threaded interface. The normally closed contact of the pneumatic-electric conversion switch 1 is connected to the 24V power supply and the audible and visual warning light via a wire. In application, the circuit is directly triggered by the gas pressure, without the need for PLC or sensor intervention, thereby reducing system complexity and failure rate. At the same time, the threaded interface connection ensures airtightness and avoids false triggering caused by air leakage.
[0026] Reference Figure 1 and Figure 2 The trigger pressure threshold of the gas-electric conversion switch 1 is 0.4-0.6MPa. The gas-electric conversion switch 1 is installed on the mounting bracket 3, and the mounting bracket 3 is located at the end of the valve island output pipeline. In application, the 0.4-0.6MPa pressure threshold accurately corresponds to the gas supply demand at the end of the test program, avoiding premature / late warnings. At the same time, the end installation position directly senses the actual gas supply status of the valve island, eliminating pipeline pressure loss interference.
[0027] Reference Figure 2 and Figure 3The pneumatic-electric conversion switch 1 is equipped with a quick-connect connector 4 (SMC KQ2H06-01AS type quick-connect connector), and the pneumatic-electric conversion switch 1 is connected to the air source input pipeline of the EOL valve island through the quick-connect connector 4. The quick-connect connector 4 is embedded with an O-ring 401, which is made of fluororubber. In application, the quick-connect structure shortens the equipment replacement time and improves the reuse rate of production line equipment. The fluororubber material is resistant to hydraulic oil corrosion (its life is 3 times longer than that of ordinary nitrile rubber) and is suitable for high humidity and oily environments.
[0028] Reference Figure 1 and Figure 2 The audible and visual warning light includes a buzzer 201 mounted on the mounting bracket 3 and a rotating warning light 202 located above the buzzer 201. The sound pressure level of the buzzer 201 is 85dB±3dB, and the rotating warning light 202 is a red strobe mode with a flashing frequency of 2Hz. In application, the 85dB buzzer sound has a coverage radius of 8 meters, and the 2Hz red strobe can still be identified under strong light in the workshop.
[0029] Reference Figure 1 and Figure 2 The mounting bracket 3 is made of aluminum alloy and can be detachably installed on the test bench guide rail. The bottom of the mounting bracket 3 has an adapter groove 301 corresponding to the guide rail, and a fixing hole 302 is provided on the adapter groove 301. The mounting bracket 3 is installed on the test bench guide rail through the adapter groove 301, the fixing hole 302 and the fasteners. In application, the aluminum alloy material achieves lightweight and corrosion resistance, and is suitable for humid / oily working conditions. At the same time, the structure of the guide rail adapter groove 301 and the fixing hole 302 is compatible with ISO standard benches, which can reduce deployment time.
[0030] Reference Figures 1-3 After the pneumatic-electric conversion switch 1 is triggered, the continuous working time of the audible and visual warning light is set to 15s±1s. In application, the 15s±1s duration matches the average movement time of the operator, avoiding premature warnings that lead to wasted time. At the same time, the mechanical pneumatic circuit trigger automatically cuts off the power supply, eliminating the need for manual reset.
[0031] The working principle of this utility model is as follows: By installing the pneumatic-electric conversion switch 1 to the end of the gas source output pipe of the valve island through the G1 / 4 threaded interface, and connecting the normally closed contact of the pneumatic-electric conversion switch 1 to the power supply terminal of the audible and visual warning light with a wire, during the test, the operator needs to arrive at the equipment station within 15 seconds after the audible and visual warning light is triggered to complete the module replacement or reset operation. In this way, the sense of urgency can be enhanced by visualization, which can promote the efficient progress of the task, thereby promoting the execution of standardized processes, reducing the standby time due to human error, and effectively reducing production and operation costs.
[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
