[0002] Remote controls are widely used in daily life, such as television remote controls and air conditioner remote controls. They typically contain electronic components and require a certain degree of airtightness to prevent the ingress of dust, moisture, and other impurities, thus ensuring the normal lifespan and performance stability of the remote control. Currently, existing methods for testing the airtightness of remote controls have many shortcomings. Common testing methods, such as simple pressure decay tests, have low accuracy and are unable to detect minute leaks, leading to the failure to detect some potential airtightness problems in a timely manner, thereby affecting the lifespan and performance stability of the remote control. Furthermore, traditional testing methods mostly rely on manual operation, which is not only inefficient but also susceptible to human factors, making it difficult to guarantee consistency and accuracy. This fails to meet the high-efficiency and high-precision requirements of modern large-scale industrial production for remote control airtightness testing. Utility Model Content

[0034] like Figures 1-5 As shown in the figure, this embodiment provides a remote control airtightness testing device. The remote control airtightness testing device includes an L-shaped bracket 1, a testing component 2 and a fixing component 3 on the bracket 1; the bracket 1 also has a control component 4.

[0035] The detection assembly 2 includes a lower mold base 21 fixedly mounted on a bracket 1. An upper cavity cover 22, which slides vertically on the bracket 1, is located directly above and parallel to the lower mold base 21, ensuring accurate and complete sealing of the closed space. An electric push rod 23 for driving the upper cavity cover 22 to slide is fixedly mounted on the bracket 1. A small air pump 24 is also fixedly mounted on the bracket 1. An air pipe 25, fixedly mounted on the small air pump 24, is connected to the upper cavity cover 22. A gas flow sensor 26 is connected to the outlet of the air pipe 25. A pressure regulating valve 27 is fixedly mounted at the outlet of the small air pump 24. A pressure sensor 28 is fixedly mounted inside the upper cavity cover 22. A sealing gasket 29, made of high-temperature resistant and wear-resistant rubber, is fixedly connected to the lower mold base 21 to ensure the sealing performance of the detection cavity in the closed state.

[0036] The gas flow sensor 26 has a measurement range of 0-1000 ml / min and a measurement accuracy of ±1 ml / min. Employing a high-precision gas flow sensor 26, it detects the flow rate of gas leaking from the detection chamber at a set pressure. By monitoring the gas leakage flow rate, the airtightness of the remote control can be more accurately determined, and even minute leaks can be precisely detected. The pressure regulating valve 27 has a pressure adjustment range of 0-1 MPa and an adjustment accuracy of ±0.005 MPa. Employing a high-precision electronic pressure regulating valve 27, it can precisely regulate the gas pressure entering the upper chamber cover 22. The pressure sensor 28 has a measurement accuracy of ±0.01 kPa. Using a high-sensitivity pressure sensor 28, it monitors the gas pressure changes in the detection chamber in real time, converting the pressure signal into an electrical signal and transmitting it to the control component 4.

[0037] like Figures 1-4 As shown, the fixing component 3 includes a receiving block 31 fixedly installed in the lower mold base 21. The receiving block 31 has multiple vacuum adsorption holes 32 evenly distributed on it. The receiving block 31 is made of aluminum alloy and has undergone surface anodizing treatment, providing good wear resistance and conductivity. Its surface has multiple vacuum adsorption holes 32. By connecting an external small vacuum pump 33, the remote control can be tightly adsorbed and fixed on the receiving block 31 before testing, preventing displacement during testing and ensuring testing accuracy. A small vacuum pump 33 is fixedly installed on the bracket 1, and a pipe 34 connected to the small vacuum pump 33 and communicating with the vacuum adsorption holes 32 is fixedly connected to the small vacuum pump 33.

[0038] like Figure 4 As shown, a rubber pad 35 is installed on the vacuum adsorption hole 32 to ensure that the remote control fits snugly against the vacuum adsorption hole 32, avoiding gaps that could affect the test results. The width of the rubber pad 35 is slightly larger than the diameter of the vacuum adsorption hole 32. The total length and width of the vacuum adsorption hole 32 are both slightly smaller than the remote control to be tested, ensuring stable and accurate adsorption of the remote control while avoiding excessive size that could affect the test results.

[0039] like Figure 2As shown, the control component 4 includes a touch screen 41 fixedly mounted on the bracket 1. The touch screen 41 allows for interaction with the operator, who can easily set detection parameters such as detection pressure, detection time, and leakage flow threshold. The operator can also view pressure change curves, flow rates, and detection results in real time. The human-machine interface also has data storage and query functions, enabling the recording and statistical analysis of historical detection data for quality traceability and production management. A controller 42 is fixedly installed inside the bracket 1. The programmable logic controller 42 (PLC) serves as the core control unit, responsible for receiving and processing signals from the pressure sensor 28, gas flow sensor 26, and other detection elements. It precisely controls actuators such as the small air pump 24, small vacuum pump 33, and audible and visual warning lights 5 according to preset programs and parameters.

[0040] like Figure 2 As shown, an audible and visual warning light 5 is fixedly installed on the bracket 1. When the remote control's airtightness is detected to be non-compliant with preset standards, such as a pressure drop exceeding a set threshold or a gas leakage flow exceeding the allowable value, the control component 4 will trigger the alarm device. The audible and visual warning light 5 is installed on the top of the bracket 1, emitting a clear audible and visual signal to remind operators to promptly detect defective products. The volume of the audible and visual alarm is adjustable to ensure that the alarm sound can be clearly heard in the production environment.

[0041] During operation, the operator places the remote control to be tested on the receiving block 31 inside the lower mold base 21, and activates the electric push rod 23 to close the upper chamber cover 22, forming the testing space. A small vacuum pump 33 is activated via the touchscreen 41, creating negative pressure in the vacuum suction holes 32 on the receiving block 31, tightly adsorbing and fixing the remote control onto the receiving block 31 to prevent displacement during testing. The testing parameters, including testing pressure, testing time, and leakage flow threshold, are then set on the touchscreen 41. The small air pump 24 and pressure control system are then activated, adjusting the pressure to the set level via the pressure regulating valve 27, and the air enters the testing space. Simultaneously, the pressure sensor 28 monitors the gas pressure changes within the testing space in real time and transmits the pressure signal to the controller 42. Once the gas pressure in the testing space reaches the set value, the controller 42 maintains a stable gas pressure and activates the gas flow sensor 26 to monitor the gas leakage flow. Within the set detection time, the controller 42 analyzes and judges the data fed back by the pressure sensor 28 and the gas flow sensor 26. If the pressure drop does not exceed the set threshold and the gas leakage flow is less than the allowable value, the remote control is judged to be airtight; otherwise, it is judged to be unqualified. The remote control airtightness detection device of this utility model can accurately detect the airtightness of the remote control, effectively detect minute leaks, greatly improve the detection accuracy, ensure the product quality of the remote control, and reduce the product failure rate and after-sales maintenance costs caused by airtightness problems.

[0042] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
