DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Embodiment one

[0029] Please refer to Figure 1 and Figure 2 The present application is an unmanned leak detection device, which comprises a conveying assembly 100 and a detection assembly 200 arranged outside the conveying assembly 100.

[0030] The conveying assembly 100 comprises a frame 101, a conveying belt 102 loaded inside the frame 101, and a driving motor 103 for driving the conveying belt 102 through a shaft member. Anti-skid grooves are arranged equidistantly and continuously on the outer side of the conveying belt 102. The conveying assembly 100 is used for continuous conveying and transferring of the air conditioner outdoor unit assembly 400. During the conveying process, automatic detection of the detection assembly 200 is matched, which effectively improves the detection efficiency of the air conditioner outdoor unit assembly 400. The driving motor 103 drives the conveying belt 102 to convey the air conditioner outdoor unit assembly 400 through a known transmission structure. The anti-skid grooves arranged on the surface of the conveying belt 102 are used to assist the stable placement of the subsequent bottom plate 301.

[0031] The detection assembly 200 comprises a mounting plate 201, a base 202 fixed to the upper side of the mounting plate 201, a multi-axis mechanical arm 203 loaded on the upper part of the base 202, and a gas monitoring sensor 204 arranged at the end of the multi-axis mechanical arm 203. The multi-axis mechanical arm 203 moves freely in a three-dimensional space, driving the gas monitoring sensor 204 to the position to be detected. The gas monitoring sensor 204 detects the concentration of freon gas by using the principles of electrochemistry, infrared absorption or photoionization, and the output data is transmitted to the controller for analysis. If an abnormally high gas concentration is detected, it indicates that there may be a leak.

[0032] Specifically, the detection assemblies 200 are oppositely arranged, and the gas monitoring sensors 204 in the detection assemblies 200 are located at the circulating parts of the air conditioner outdoor unit assemblies 400. The base 202 is embedded with a controller. The controller is provided with a plurality of interfaces. The interfaces are connected to an external power supply or a control end through connecting lines. The multi-axis mechanical arm 203 is provided with a multi-degree-of-freedom joint. The multi-axis mechanical arm 203 is connected to the controller in the base 202 through internal wires. The controller processes the data from the photoelectric sensor and the gas monitoring sensor 204 through the built-in program, and controls the action of the multi-axis mechanical arm 203.

[0033] Further, the conveying assembly 100 is provided with a photoelectric sensor. The photoelectric sensor is fixed to the upper edge of the rack 101, and the photoelectric sensor corresponds to the position of the detection assembly 200. The photoelectric sensor is used to monitor whether the air conditioner outdoor unit assembly 400 conveyed by the conveying belt 102 reaches the specified position. When the object blocks the light, the photoelectric sensor generates a signal to trigger the controller in the base 202 to start the corresponding detection process of the detection assembly 200. The driving motor 103 is fixed to one end of the rack 101. The bottom closed surface of the rack 101 is fixed to an external support structure (such as the ground or a special platform) to ensure the stability and safety of the entire system during operation. The conveying assembly 100 at both ends is matched with the upstream and downstream detection processes to realize the multi-process continuous detection of the air conditioner outdoor unit assembly 400.

[0034] The operation process of the embodiment is as follows:

[0035] Input or select the appropriate detection program in the controller, set the working parameters (such as sensitivity, detection threshold) of the gas monitoring sensor 204, and adjust the action path and speed of the multi-axis mechanical arm 203 to adapt to different models of air conditioner outdoor unit assemblies 400.

[0036] The air conditioner outdoor unit assembly 400 to be detected is placed at the starting end of the conveying belt 102, the anti-skid groove helps to stabilize the object and prevent displacement during transportation, the driving motor 103 drives the conveying belt 102 to move through the transmission structure, and the air conditioner outdoor unit assembly 400 is smoothly conveyed along the predetermined path to the detection area;

[0037] When the air conditioner outdoor unit assembly 400 reaches the monitoring range of the photoelectric sensor, the photoelectric sensor detects the presence of the object and sends a signal to the controller. After the controller receives the signal, it triggers the detection assembly 200 to prepare for the next operation. The controller controls the multi-axis mechanical arm 203 to move the gas monitoring sensor 204 to the vicinity of the circulating part of the air conditioner outdoor unit assembly 400 according to the preset program. The gas monitoring sensor 204 starts detection, measures the concentration of freon gas using electrochemical, infrared absorption or photoionization principles, and transmits real-time data to the controller.

[0038] The controller receives data from the gas monitoring sensor 204 and analyzes it. If an abnormally high gas concentration is detected, it may indicate a leak. According to the detection results, the controller can issue an alarm or mark the problematic air conditioner outdoor unit assembly 400 for subsequent processing. After detection is complete, the air conditioner outdoor unit assembly 400 continues to be conveyed along the conveying belt 102 to the next process point or collection area.

The anti-skid protrusions 307 cooperate with the anti-skid grooves to increase the friction between them, further improving the stability of the positioning assembly 300 during transportation. When it is necessary to fix the air conditioner outdoor unit assembly 400, the air rods 304 are controlled to retract or extend, driving the clamping plates 306 to move to achieve clamping action.

[0041] Specifically, the bottom of the air conditioner outdoor unit assembly 400 is clamped and fixed between the clamping plates 306, and guide rods 305 are fixed to the edges of the clamping plates 306. The other ends of the guide rods 305 are movably arranged in the mounting seats 303, ensuring accurate movement of the clamping plates 306 along the predetermined path during clamping.

[0042] Further, the bottom plate 301 upper side edge part is fixed with a support column 302, which is attached to the bottom of the air conditioner outdoor unit assembly 400, plays a supporting role, reduces the pressure of the air conditioner outdoor unit assembly 400 on the clamp plate 306, and also provides additional stability for the object.

[0043] The operation process of the embodiment is as follows: the positioning assembly 300 flows with the air conditioner outdoor unit assembly 400 in the multi-channel detection process, provides stable support for the air conditioner outdoor unit assembly 400, places the bottom of the air conditioner outdoor unit assembly 400 on the support column 302 during assembly, then starts the air rod 304, the telescopic end drives the clamp plate 306 to clamp and fix the air conditioner outdoor unit assembly 400, and in the subsequent conveying process, the anti-skid protrusions 307 on the bottom of the bottom plate 301 cooperate with the anti-skid grooves to ensure the stable movement of the positioning assembly 300 and the air conditioner outdoor unit assembly 400 as a whole.
