Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner production, in particular to an air conditioner leakage detection tool, an air conditioner leakage detection device and an air conditioner automatic leakage detection system. Background Art

[0002] In the production process of air conditioners, static leak detection of finished air conditioners is a key link to ensure product quality and user safety. Especially in the refrigeration system of air conditioners, since most refrigeration systems are connected by copper pipes and each connection point is welded by welding, there will be welding quality risks in the welding process. The quality of the welding points is not up to standard, which can easily lead to refrigerant leakage. Therefore, it is necessary to static leak detection of finished air conditioners to determine whether there is refrigerant leakage. Traditional air conditioner leak detection methods mostly use manual detection, which is not only inefficient, but also easily affected by human factors, resulting in inaccurate detection results. With the improvement of the automation level of the manufacturing industry, more and more companies are beginning to seek to realize the automation and intelligence of air conditioner leak detection through automated equipment. Although there are some devices for automatic leak detection of finished air conditioners, these devices still have defects in practical applications. For example, when the metal leak detection probe of the leak detection equipment pierces the packaging foam of the air conditioner, the foam debris generated can easily block the leak detection hole of the probe, causing the leak detection equipment to falsely alarm and affect the accuracy of the detection results; and this requires the equipment to be shut down so that the staff can clean the probe in time, which greatly reduces the leak detection efficiency.

[0003] Therefore, it is necessary to improve the existing air conditioning leak detection equipment to overcome the defects of the prior art. Utility Model Content

[0004] In order to overcome the problems existing in the related technology, one of the purposes of the utility model is to provide an air-conditioning leak detection tool, which can absorb and store foam debris through a receiving groove, thereby reducing the risk of foam debris clogging the leak detection hole, and helping to improve the efficiency of air-conditioning leak detection.

[0007] The leak detection tool of the present application reduces the influence of foam debris on the leak detection hole through the design of the receiving groove, avoids the leak detection error caused by debris blockage, and thus significantly improves the accuracy of leak detection. Since the leak detection hole is less blocked by debris, the false alarm rate of the leak detection equipment is also reduced accordingly, avoiding unnecessary inspection and maintenance work.

[0008] In a preferred technical solution of the utility model, the accommodating groove is arranged in the middle of the wall-breaking member, the edge of the accommodating groove forms a wall-breaking edge, and the thickness of the wall-breaking edge gradually increases along the direction from the second probe to the first probe.

[0009] The design of gradually thickening the breaking edge not only provides good mechanical support and ensures the durability and reliability of the probe during use, but also reduces the debris generated in the process of breaking the foam, thereby reducing the probability of foam debris blocking the leak detection hole.

[0013] The air suction terminal is connected to the leak detector, and the gas entering from the leak detection hole enters the leak detector through the air suction terminal. Specifically, the air suction terminal and the leak detector can be connected through a pipeline, and an air pump is arranged on the pipeline.

[0014] The accommodating cavity can protect the suction terminal, thereby extending the service life of the leak detection tool. The accommodating cavity should be larger than the outer diameter of the suction terminal so that the gas in the accommodating cavity can enter the suction terminal.

[0015] In a preferred technical solution of the utility model, a plurality of leak detection holes are arranged on the second probe, the leak detection holes are communicated with the accommodating cavity, and a filter screen is arranged on each of the leak detection holes.

[0016] The setting of multiple leak detection holes can bring a larger gas absorption area, so that the leak detection process can be completed more quickly. The addition of the filter effectively blocks impurities such as foam debris, ensures the smooth flow of the leak detection holes, and reduces the risk of equipment failure and false alarms.

[0017] The second purpose of the utility model is to provide an air-conditioning leak detection device, which includes a leak detector and the air-conditioning leak detection tool as described above.

[0018] In a preferred technical solution of the utility model, a control cabinet is further included, the leak detector is arranged in the control cabinet, a control device is arranged on the control cabinet, and the control device is electrically connected to the leak detector.

[0019] In a preferred technical solution of the utility model, it also includes a driving robot, the driving robot is provided with a driving arm, the driving arm is provided with a mounting seat, and the air-conditioning leak detection tool is arranged on the mounting seat.

[0020] The driving robot drives the mounting base to move via the driving arm, thereby driving the air-conditioning leak detection tooling, so that the air-conditioning leak detection tooling can perform leak detection on the finished air-conditioning, so as to improve the efficiency of static leak detection of the air-conditioning.

[0021] In a preferred technical solution of the utility model, an air blowing pipe is arranged on the mounting seat, the air blowing pipe is externally connected to an air pressure pump, and the air blowing pipe is arranged toward the second probe.

[0022] When foam debris or other impurities are attached to the second probe, the staff can start the air pressure pump and blow a strong airflow to the second probe through the air pipe to effectively remove the debris attached to the probe.

[0023] The third purpose of the utility model is to provide an automatic air-conditioning leak detection system, which includes a conveyor line and the air-conditioning leak detection device as described above, wherein the conveyor line is used to convey finished air-conditioners, and the air-conditioning leak detection device is arranged on one side of the conveyor line.

[0024] In a preferred technical solution of the utility model, the finished air conditioner includes an air conditioner, a packaging box and packaging foam, the packaging foam is coated on the outside of the air conditioner, a leak detection hole is provided on the packaging foam, the diameter of the leak detection hole is 20-25mm, and a sealing foam is provided at the leak detection hole, the thickness of the sealing foam is 1.5mm-2mm.

[0025] The automatic air conditioner leak detection system also includes improvements to the packaging foam of the air conditioner. Through the design improvement of the sealing foam, the foam debris generated when the air conditioner is statically leak-detected can be reduced, thereby improving the accuracy of the air conditioner leak detection and improving the leak detection efficiency.

[0026] The beneficial effects of the utility model are:

[0027] The utility model provides an air conditioner leak detection tool, which includes a first probe and a second probe, and the first probe is used to connect with a leak detector. The second probe is provided with a leak detection hole, one end of the second probe is detachably connected to the first probe, and the other end is provided with a wall-breaking piece, and the wall-breaking piece is provided with a receiving groove, and the receiving groove is arranged on a side wall of the wall-breaking piece away from the first probe. One end of the second probe is detachably connected to the first probe, so that the entire air conditioner leak detection tool is easy to carry and store, and it is also convenient to quickly replace or repair the probe when necessary. In the process of air conditioner leak detection, the wall-breaking piece is used to poke the packaging foam of the air conditioner, and the gas in the air conditioner packaging is absorbed through the leak detection hole. The gas in the air conditioner is transmitted to the leak detector through the first probe, so that the leak detector can judge whether the air conditioner has a refrigerant leak. In the process of piercing the packaging foam of the air conditioner, most of the foam debris generated will fall into the receiving groove and be stored in the receiving groove, which can reduce the amount of foam debris outside the probe, thereby reducing the risk of foam debris blocking the leak detection hole, reducing the false alarm of the leak detection equipment, and reducing the frequency of staff cleaning the probe, thereby improving the efficiency of air conditioner leak detection.

[0039] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0040] In the production process of air conditioners, static leak detection of finished air conditioners is a key link to ensure product quality and user safety. Especially in the refrigeration system of air conditioners, since most refrigeration systems are connected by copper pipes and each connection point is welded by welding, there will be welding quality risks in the welding process. The quality of the welding points is not up to standard, which can easily lead to refrigerant leakage. Therefore, it is necessary to static leak detection of finished air conditioners to determine whether there is refrigerant leakage. Traditional air conditioner leak detection methods mostly use manual detection, which is not only inefficient, but also easily affected by human factors, resulting in inaccurate detection results. With the improvement of the automation level of the manufacturing industry, more and more companies are beginning to seek to realize the automation and intelligence of air conditioner leak detection through automated equipment. Although there are some devices for automatic leak detection of finished air conditioners, these devices still have defects in practical applications. For example, when the metal leak detection probe of the leak detection equipment pierces the packaging foam of the air conditioner, the foam debris generated can easily block the leak detection hole of the probe, causing the leak detection equipment to falsely alarm and affect the accuracy of the detection results; and this requires the equipment to be shut down so that the staff can clean the probe in time, which greatly reduces the leak detection efficiency.

[0041] Based on this, the present application provides an air conditioning leak detection tool.

[0042] Example 1

[0043] like Figure 1-Figure 8 As shown, the air conditioner leak detection tool provided in this embodiment includes a first probe 1 and a second probe 2, and the first probe 1 is used to connect with the leak detector 120. The second probe 2 is provided with a leak detection hole 22, one end of the second probe 2 is detachably connected to the first probe 1, and the other end opposite to the second probe 2 is provided with a wall breaking member 21, and the wall breaking member 21 is provided with a receiving groove 211, and the receiving groove 211 is provided on a side wall of the wall breaking member 21 away from the first probe 1.

[0044] In actual application, the accommodating groove 211 is arranged on a side wall of the air-conditioning packaging foam 410 where the wall-breaking member 21 pierces.

[0045] One end of the second probe 2 is detachably connected to the first probe 1, so that the entire air conditioner leak detection tool is easy to carry and store, and is also convenient for quickly replacing or repairing the probe when necessary. During the air conditioner leak detection process, since the air conditioner is placed in the packaging foam 410, the leak detection port reserved in the packaging foam 410 needs to be pierced during the leak detection, so that the probe can penetrate into the air conditioner packaging and absorb the gas in the packaging for the leak detector 120 to detect.

[0046] The leak detection tool of the present application utilizes a wall-breaking piece 21 to pierce the packaging foam 410 of the air conditioner, and absorbs the gas in the air conditioner packaging through the leak detection hole 22. The gas in the air conditioner is transmitted to the leak detector 120 through the first probe 1, so that the leak detector 120 can determine whether the air conditioner has a refrigerant leak.

[0047] More specifically, the wall-breaking member 21 may be made of metal with a smooth surface to reduce the generation of foam debris.

[0048] When the leak detection tool of the present application punctures the packaging foam 410 of the air conditioner, most of the foam debris generated will fall into the receiving groove 211 and be stored in the receiving groove 211, which can reduce the amount of foam debris outside the probe, thereby reducing the risk of foam debris clogging the leak detection hole 22, reducing false alarms caused by the leak detection equipment, and reducing the frequency of staff cleaning the probe, thereby improving the efficiency of air conditioner leak detection.

[0049] The second probe 2 can be detachably connected to the first probe 1 by a threaded connection. The connection parts of the first probe 1 and the second probe 2 are respectively provided with an external thread and an internal thread. By rotating, the external thread of the first probe 1 is tightly combined with the internal thread of the second probe 2, thereby achieving a stable connection. When disassembling, it can be separated by simply rotating in the opposite direction.

[0050] The second probe 2 may be detachably connected to the first probe 1 by a snap-on connection, which is a method of achieving quick connection and disassembly through a snap-on structure. The first probe 1 and the second probe 2 are respectively provided with a snap-on and a slot that cooperate with each other. When connecting, align the snap-on with the slot and lightly press to achieve connection. When disassembling, just press the release button on the snap-on or pull the snap-on to separate.

[0051] In other embodiments, the second probe 2 can be detachably connected to the first probe 1 by magnetic connection. The connection parts of the first probe 1 and the second probe 2 are respectively equipped with magnets, and the connection of the probes is achieved by the suction of the magnets. This connection method does not require alignment and rotation, and the two probes can be automatically adsorbed together by simply bringing them close together. When disassembling, the two can be separated by force.

[0052] It should be noted that no matter which connection method is used, the connection between the first probe 1 and the second probe 2 needs to ensure good airtightness to reduce gas leakage.

[0053] Example 2

[0054] This embodiment is improved on the basis of embodiment 1.

[0055] like Figure 1-Figure 8 As shown, in this embodiment, the structure of the wall breaking head is optimized. The receiving groove 211 is arranged in the middle of the wall breaking member 21, and the edge of the receiving groove 211 forms a wall breaking edge 212, and the thickness of the wall breaking edge 212 gradually increases along the direction from the second probe 2 to the first probe 1.

[0056] In practical applications, the thickness of the side of the wall-breaking edge 212 used for breaking the wall is small, which can increase the pressure of the wall-breaking edge 212 on the foam when breaking the foam, thereby improving the efficiency of breaking the foam.

[0057] The design of gradually thickening the wall-breaking edge 212 not only provides good mechanical support and ensures the durability and reliability of the probe during use, but also the tip of the wall-breaking edge 212 can reduce the debris generated during the foam-breaking process, thereby reducing the probability of foam debris blocking the leak detection hole 22.

[0058] Example 3

[0059] This embodiment is improved on the basis of embodiment 1.

[0060] like Figure 1-Figure 8 As shown, in this embodiment, the width of the receiving groove 211 is 1 cm-1.5 cm, and the depth of the receiving groove 211 is 0.8 cm-1 cm.

[0061] The size design of the receiving groove 211 of the present application is based on comprehensive consideration of the size and distribution of foam debris and the amount of debris that may be generated during the leak detection process. The width of 1 cm to 1.5 cm is sufficient to accommodate most foam debris, while not being too large to affect the overall size and portability of the probe. The depth of 0.8 cm to 1 cm ensures that the debris can be stably stored after falling into the receiving groove 211 and will not be easily blown out or overflowed.

[0062] In actual application, when the staff uses the probe to detect air conditioner leaks, the precisely designed receiving groove 211 can efficiently collect and store the foam debris generated during the wall breaking process. Since the receiving groove 211 is of moderate size, it can minimize the interference of the foam debris on the leak detection process without affecting the normal operation of the probe.

[0063] In addition, this size design also takes into account the durability and maintenance convenience of the probe. The moderate size of the receiving slot 211 means that the probe can maintain good performance during long-term use and is relatively simple to maintain.

[0064] Example 4

[0065] This embodiment is improved on the basis of embodiment 1.

[0066] like Figure 1-Figure 8 As shown, in this embodiment, the first probe 1 is provided with an air suction terminal 11, and the second probe 2 is provided with an accommodating cavity, and the air suction terminal 11 is arranged in the accommodating cavity;

[0067] The accommodating cavity can protect the air suction terminal 11, thereby extending the service life of the leak detection tool.

[0068] Furthermore, in this embodiment, a plurality of leak detection holes 22 are provided on the second probe 2, the leak detection holes 22 are connected to the accommodating cavity, and a filter screen 23 is provided on each of the leak detection holes 22. The leak detection holes 22 are connected to the accommodating cavity so that the gas in the air conditioner can be effectively absorbed and transferred to the leak detector 120.

[0069] The provision of multiple leak detection holes 22 can provide a larger gas absorption area, thereby enabling the leak detection process to be completed more quickly. The addition of the filter 23 effectively blocks impurities such as foam debris, ensures the smooth flow of the leak detection holes 22, and reduces the risk of equipment failure and false alarms.

[0070] Specifically, the leak detection hole 22 can be designed to be circular, rectangular or oblong. The filter screen 23 can be bonded in the leak detection hole 22. A plurality of leak detection holes 22 can be evenly distributed on the outer wall of the second probe 2 to ensure that gas can be evenly inhaled from multiple directions.

[0071] Example 5

[0072] like Figure 1-Figure 8 As shown, this embodiment provides an air-conditioning leak detection device, which includes a leak detector 120 and an air-conditioning leak detection tool as described in any one of Embodiments 1-4.

[0073] In this embodiment, the leak detection tool further includes a control cabinet 100 , in which the leak detector 120 is disposed. A control device 110 is disposed on the control cabinet 100 , and the control device 110 is electrically connected to the leak detector 120 .

[0074] Specifically, the control cabinet 100 is a cabinet, the control device 110 is arranged on the top of the cabinet, and the leak detector 120 is arranged in the cabinet.

[0075] The working principle of the leak detector 120 of the present application can be to perform refrigerant leak detection based on the principle of electromagnetic waves, and is mainly used to detect whether there is refrigerant in the gas in the air-conditioning package absorbed by the tooling.

[0076] The principle of refrigerant leak detection based on the electromagnetic wave principle is as follows: the specific electromagnetic wave signal generated when the refrigerant leaks is used for detection. The fluorine in the refrigerant generates specific electromagnetic waves when it burns. The leak detector 120 determines whether the refrigerant leaks and the extent of the leak by receiving and analyzing these signals.

[0077] It is also possible to detect using the principle of ultraviolet light: using the ultraviolet radiation generated when a refrigerant leaks. When the refrigerant leaks, it reacts with moisture or oxidants in the air, which produces visible fluorescence. The leak detector 120 uses an ultraviolet lamp to emit ultraviolet light and observes whether the gas sent by the tooling has a refrigerant leak through a special filter.

[0078] Alternatively, the detection may be performed using the principle of electrochemistry: the detection may be performed using the gas reaction generated when the refrigerant leaks. The refrigerant reacts with the chemical substances in the gas sensor to generate electrical signals, which are received and analyzed by the leak detector 120 to determine the extent of the refrigerant leakage.

[0079] In this embodiment, a driving robot 200 is further included. The driving robot is provided with a driving arm 210 . The driving arm 210 is provided with a mounting seat 220 . The air-conditioning leak detection tool is provided on the mounting seat 220 .

[0080] The driving robot 200 drives the mounting seat 220 to move by driving the arm 210, thereby driving the air conditioner leak detection tooling, so that the air conditioner leak detection tooling can perform leak detection on the finished air conditioner 400, so as to improve the efficiency of static leak detection of the air conditioner.

[0081] The base of the driving robot 200 of the present application is movable so as to move the robot to a target position as required.

[0082] In actual operation, the staff can easily manipulate the air conditioner leak detection tool to perform fast and accurate leak detection between each finished air conditioner 400 by simply controlling the driving robot 200. This automated operation method not only reduces human operation errors, but also greatly improves work efficiency, making the quality inspection link of the air conditioner production line more efficient and reliable.

[0083] The air conditioner leak detection device of the present application can realize automatic leak detection of the air conditioner. The automated operation mode reduces the interference of human factors, reduces the possibility of operating errors, and improves the accuracy of detection. The staff does not need to manually move and position the leak detection tooling, which greatly reduces the workload and improves the comfort of work. In addition, efficient and accurate leak detection work helps to timely discover and deal with quality problems of the finished air conditioner 400, thereby improving the quality level of the entire production line.

[0084] In a further implementation of the present embodiment, an air blowing pipe 230 is disposed on the mounting base 220 , the air blowing pipe 230 is externally connected to an air pressure pump, and the air blowing pipe 230 is disposed toward the second probe 2 .

[0085] The air pressure pump connected to the air blowing pipe 230 can provide a stable and strong airflow. When foam debris or other impurities are attached to the second probe 2, the operator can start the air pressure pump to blow a strong airflow to the second probe 2 through the air blowing pipe 230 to effectively remove the debris attached to the probe.

[0086] This design not only improves the cleaning efficiency of the probe and reduces the tediousness of manual cleaning, but also avoids the probe being blocked by debris during the leak detection process, which affects the accuracy of the leak detection result. In addition, the direction of the air blow pipe 230 is set to align with the second probe 2, ensuring the pertinence and efficiency of the cleaning effect.

[0087] The working process of the air conditioner leak detection device of the present application is described in detail below:

[0088] First, the various parts of the leak detection device are connected to ensure that the gas sampled by the leak detection tool can be transmitted to the leak detector 120. In addition, the leak detection tool needs to be cleaned before leak detection to avoid contamination affecting the leak detection result.

[0089] Including cleaning probes, charging batteries, connecting sensors, etc. At the same time, select appropriate sensing technology and set related parameters according to specific detection requirements.

[0090] A sensor network is arranged on the production line to ensure that each finished air conditioner 400 can be effectively monitored. The air conditioner leak detection tool is installed on the mounting base 220 of the driving robot 200, and necessary calibration and testing are performed. The leak detection task and related parameters are set in the control device 110.

[0091] The driving robot 200 performs leak detection on the finished air conditioner 400 on the production line along a preset path according to the instruction of the control device 110. When the finished air conditioner 400 reaches the preset position, the driving robot 200 drives the leak detection tool to move. When the driving leak detection tool arrives near the finished air conditioner 400 to be leak-detected, the control device 110 confirms the position and state of the finished air conditioner 400 to be leak-detected through the sensor. Once it is confirmed that the finished air conditioner 400 to be leak-detected is in a leak-detectable state, the control device 110 will instruct the driving robot 200 to align the air conditioner leak detection tool with the leak detection port 4101 of the finished air conditioner 400, and the driving robot 200 drives the leak detection tool to pierce the packaging foam 410 of the air conditioner, and the second probe 2 penetrates into the packaging foam 410 of the air conditioner, so that gas sampling can be performed. Specifically, the second probe 2 is inserted into the packaging box 430 of the finished air conditioner 400 to a depth of 80-120 mm and is maintained for more than 3S.

[0092] The leak detector 120 receives the sample of the gas inside the packaging box 430 of the finished air conditioner 400 obtained by the leak detection tool. The leak detector analyzes the gas to determine whether there is a refrigerant leak in the air conditioner in the packaging box 430. If the leak detector 120 determines that there is a refrigerant leak, an alarm will be issued, and if it is determined that there is no leak, no alarm will be issued. After the static leak detection is completed, the robot 200 is driven to retreat, the leak detection tool is pulled out, and the air blowing pipe 230 is automatically opened at the same time to blow the second probe 2. The blowing time is set to 2S, so as to clean up the debris remaining on the metal probe filter 23 to prevent the debris from being squeezed and blocking the leak detection hole 22.

[0093] Example 6

[0094] like Figure 1-Figure 8 As shown, this embodiment provides an automatic air conditioner leak detection system, which includes a conveyor line 300 and the air conditioner leak detection device as described above, wherein the conveyor line 300 is used to convey finished air conditioners 400, and the air conditioner leak detection device is arranged on one side of the conveyor line 300.

[0095] In this embodiment, the finished air conditioner 400 includes an air conditioner 420, a packaging box 430 and a packaging foam 410. The packaging foam 410 is wrapped around the outside of the air conditioner 420. A leak detection port 4101 is provided on the packaging foam 410. The diameter of the leak detection port 4101 is 20-25 mm. A sealing foam 4102 is provided at the leak detection hole 22. The thickness of the sealing foam 4102 is 1.5 mm-2 mm.

[0096] Specifically, a leak detection station is provided on the conveyor line 300 , and a blocking mechanism is provided on one side of the leak detection station for blocking and limiting the finished air conditioner 400 so that the air conditioner leak detection device can perform leak detection on the air conditioner.

[0097] Since the packaging foam 410 of the air conditioner is thick as a whole, when the metal probe pierces the packaging foam 410, the foam will crack and break to varying degrees and irregularly, and the foam will cause certain hidden dangers to the protectiveness of the finished air conditioner 400 and the packaging after the foam is broken. Therefore, the present application also provides a new design of air conditioner packaging foam 410. The packaging foam 410 reserves a leak detection port 4101, and specifically, the leak detection port 4101 corresponds to the reserved leak detection position of the air conditioner packaging box 430. The design of the sealing foam 4102 on the leak detection port 4101 will not cause the defects of loose sealing and dust entering the packaging box 430, and can reduce the debris generated by piercing the foam during leak detection. The automatic leak detection system for air conditioners improves the packaging foam 410 of the air conditioner 420. By improving the design of the sealing foam 4102, the foam debris generated when the air conditioner is statically leaked can be reduced, thereby improving the accuracy of air conditioner leak detection and improving the leak detection efficiency.

[0098] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
