[0002] Common inflatable products on the market, such as inflatable beds, inflatable tables, inflatable boats, inflatable toys, etc., are widely favored by consumers due to their many advantages such as light weight, foldability, easy portability, and good comfort. They have a very wide range of applications and have become one of the essential products for people's home use and travel, with extremely high market prospects. The airtightness of inflatable products is a key indicator for evaluating the product quality of inflatable products, and whether the airtightness is excellent directly affects the user experience of consumers for inflatable products. Therefore, most inflatable products will undergo airtightness detection, that is, air leakage detection, before being put on the market.

[0074] Inflatable product 700. Detailed implementation mode

[0075] The present invention discloses a leak detection device for an inflatable product, which reduces the leak detection time by reducing or avoiding the waiting time for leak detection, thereby improving the leak detection efficiency. The following provides two embodiments to elaborate on the content of the present invention.

[0076] Embodiment 1

[0077] As Figure 1-4 shown, the leak detection device of this embodiment is provided with a testing line 600, and the testing line 600 is equipped with an air storage tank 100, an inflation device 200, a tester 300, and an electric control box 400. Among them, the air storage tank 100 is used to store gas. The inflation device 200 is connected to the air storage tank 100, and through the inflation device 200, the gas in the air storage tank 100 can be filled into the inflatable product 700; the inflation device 200 can also be connected to the electric control box 400, and the inflation operation of the inflation device 200 is controlled by the electric control box 400. In this embodiment, the inflation device 200 is an inflation head. The tester 300 is connected to the electric control box 400, and the electric control box 400 detects whether the inflatable product 700 on the testing line 600 leaks. In this embodiment, the tester 300 can adopt a pressure tester 300, a gas mass spectrometer, or other types of testers 300. When a gas mass spectrometer is adopted, the gas in the air storage tank 100 must contain gas that can be recognized by the gas mass spectrometer.

[0078] In this embodiment, the test line 600 includes a loading station 610, a testing station 620, and an unloading station 630 arranged in sequence. The loading station 610 is provided with a loading conveyor platform 611. A loading device 612 for pushing the inflated product 700 to move from the loading station 610 to the testing station 620 is arranged on the loading conveyor platform 611. A loading lifting device 613 for driving the loading conveyor platform 611 to rise or fall is connected below the loading conveyor platform 611. The unloading station 630 is provided with an unloading conveyor platform 631. An unloading lifting device 632 for driving the unloading conveyor platform 631 to rise or fall is connected below the unloading conveyor platform 631. The testing station 620 is provided with a testing frame 621. At least two testing covers are arranged in the testing frame 621 in sequence from bottom to top. The testing covers are connected to the tester 300. A testing lifting device 623 is arranged on the testing frame 621. The testing lifting device 623 is connected to the testing cover and is used to control the up and down movement of the testing cover in the testing frame 621. The loading device, the loading lifting device, the unloading lifting device, and the testing lifting device in the test line are all connected to the electric control box and are coordinately controlled by the electric control box.

[0079] Among them, the loading conveyor platform 611 is used to carry the inflated product 700, so that the inflated product 700 can move on the loading conveyor platform 611 under the action of the loading device 612. In order to reduce the friction when the inflated product 700 moves, the loading conveyor platform 611 is set as a roller conveyor platform in this embodiment. In this embodiment, the loading device 612 includes a pushing member 6121 and a translation driving mechanism 6122. The translation driving mechanism 6122 is connected to the pushing member 6121 and drives the pushing member 6121 to approach or move away from the testing station 620. That is, under the action of the translation driving mechanism 6122, the pushing member 6121 can push the inflated product 700 placed on the loading conveyor platform 611 and send it to the testing station 620 for leak detection. The translation driving mechanism 6122 can be implemented by using a cylinder, an oil cylinder, or a motor driving structure, etc. In this embodiment, the translation driving mechanism 6122 is implemented by using a motor driving structure. It includes a translation motor 61221, a driving wheel connected to the translation motor 61221, a driven wheel 61222, and a translation transmission chain 61223 connecting the driving wheel and the driven wheel 61222. The translation transmission chain 61223 is connected to the pushing member 6121. Of course, in addition to using the pushing member 6121 to push the inflated product 700 for loading, the loading can also be carried out by using a transmission chain or a transmission roller. If this method is used for loading, the loading device 612 further includes a motor for driving the transmission chain or the transmission roller to rotate. Then the transmission chain or the transmission roller of the loading device 612 becomes the loading conveyor platform 611.

[0080] In order to enable the inflatable product 700 to accurately enter the test station 620, guiding devices 614 can be provided on both sides of the loading conveying platform 611. The guiding devices 614 can prevent the inflatable product 700 from shifting in position during the loading process. In this embodiment, the guiding device 614 is a guiding roller. Specifically, the guiding roller is rotatably arranged on the side of the loading conveying platform 611.

[0081] The unloading conveying platform 631 and the loading conveying platform 611 have the same function. In this embodiment, the unloading conveying platform 631 is also a roller conveying platform. However, no unloading device is provided at the unloading station 630 because after the leak detection is completed, the newly loaded inflatable product 700 will push the tested inflatable product 700 to the unloading station 630, thus completing the unloading work. Additionally, in this embodiment, the loading lifting device 613 and the unloading lifting device 632 are scissor-type hydraulic lifting devices.

[0082] Since more than two test covers are provided on the test station 620, and each test cover can test one inflatable product 700. Therefore, leak detection of multiple inflatable products 700 can be achieved on the test station 620. In this embodiment, two test covers are provided on the test station 620, which are the first test cover 6221 and the second test cover 6222 from bottom to top. The first test cover 6221 corresponds to the first test station 620, and the second test cover 6222 corresponds to the second test station 620. A bottom plate 6211 is provided in the test frame 621. The bottom plate 6211 is arranged below the first test cover 6221. The first test cover 6221 and the bottom plate 6211 cooperate to form a sealed test space, and the second test cover 6222 cooperates with the upper end surface of the first test cover 6221 to form a sealed test space.

[0083] The test lifting device 623 includes at least two sets of test lifting devices 623, and each test lifting device 623 cooperates with a test cover. In this embodiment, there are two sets of test lifting devices 623 in total, corresponding to the first test cover 6221 and the second test cover 6222 respectively. The test lifting device 623 can be implemented by using a cylinder, an oil cylinder or a motor drive structure. In this embodiment, the test lifting device 623 is implemented by using a motor drive. It includes a lifting drive motor 62311, a transmission rod 62312 and two lifting transmission chains 62313. The lifting drive motor 62311 is connected to the transmission rod 62312. One end of the two lifting transmission chains 62313 is connected to the transmission rod 62312, and the other end is connected to the test cover. The lifting drive motor 62311 drives the transmission rod 62312 to rotate, and the transmission rod 62312 drives the belt to move up and down, thereby driving the test cover to move up and down.

[0084] To recover gas, the detection device of the present invention further includes an air compressor, which is connected to the gas storage tank 100. After the inflatable product 700 has completed the air leakage detection, the gas in the inflatable product 700 is recovered into the gas storage tank 100 through the air compressor.

[0085] The working principle of the device in this embodiment is as follows:

[0086] Initially, under the action of the test lifting device 623, the first test cover 6221 and the second test cover 6222 move upward, leaving a space for placing the inflatable product 700 between the first test cover 6221 and the bottom plate 6211.

[0087] First-layer feeding and testing: The operator at the feeding station 610 fills the gas in the gas storage tank 100 into the inflatable product 700 to be detected through the inflation device 200. After inflation is completed, the inflatable product 700 is placed on the feeding conveying platform 611, and the feeding device 612 conveys the inflatable product 700 to be detected on the feeding conveying platform 611 onto the bottom plate 6211 of the testing station 620. The first test cover 6221 descends to cooperate with the bottom plate 6211 to form a sealed testing space, and the electronic control box 400 starts the tester 300 to detect the air leakage of the inflatable product 700 in the first test cover 6221.

[0088] Second-layer feeding and testing: During the detection of the inflatable product 700 in the first test cover 6221 by the tester 300, the operator at the feeding station 610 places the next inflatable product 700 to be detected on the feeding conveying platform 611. The feeding lifting device 613 is started, and the feeding conveying platform 611 rises above the first test cover 6221. Then the feeding device 612 sends the inflatable product 700 into the first test cover 6221 of the testing station 620. After feeding is completed, the feeding lifting device 613 descends, and at the same time, the second test cover 6222 descends to cooperate with the upper end surface of the first test cover 6221 to form a sealed detection space. The electronic control box 400 controls the tester 300, and after the detection of the first test cover 6221 is completed, immediately detect the inflatable product 700 in the second test cover 6222.

[0089] After the first test cover 6221 finishes the detection, the electric control box 400 controls the tester 300 to detect the air leakage situation of the inflated product 700 in the second test cover 6222. At the same time, the electric control box 400 controls the test lifting device 623 to move the first test cover 6221 and the second test cover 6222 upward together to perform the feeding and discharging of the first layer: The operator at the feeding station 610 places the next inflated product 700 to be detected on the feeding conveyor platform 611. The feeding device 612 pushes the inflated product 700 to be detected on the feeding conveyor platform 611 in the direction of the test station 620. While the inflated product 700 to be detected moves towards the test station 620, it will push the inflated product 700 that has been detected to move towards the discharging station 630. After the inflated product 700 to be detected is completely sent into the test station 620, the first test cover 6221 and the second test cover 6222 move downward together, and the first test cover 6221 waits for the tester 300 to perform the air leakage detection. The operator at the discharging station 630 removes the inflated product 700 that has been detected, and then recovers the gas in it to the air storage tank 100 through an air compressor.

[0090] When the detection of the second test cover 6222 is completed, the electric control box 400 controls the tester 300 to detect the first test cover 6221, and at the same time controls the second test cover 6222 to move upward to start the feeding and discharging of the second layer: The operator at the feeding station 610 places the next inflated product 700 to be detected on the feeding conveyor platform 611. The feeding lifting device 613 and the discharging lifting device 632 rise, and the feeding conveyor platform 611 and the discharging conveyor platform 631 rise to the second layer. Then the feeding device 612 pushes the inflated product 700 to be detected on the feeding conveyor platform 611 in the direction of the test station 620. While the inflated product 700 to be detected moves towards the test station 620, it will push the inflated product 700 that has been detected to move towards the discharging station 630. After the inflated product 700 to be detected is completely sent into the test station 620, the second test cover 6222 moves downward, and the second test cover 6222 waits for the tester 300 to perform the air leakage detection. At the same time, the feeding lifting device 613 and the discharging lifting device 632 descend, and the feeding conveyor platform 611 and the discharging conveyor platform 631 descend to the first layer. The operator at the discharging station 630 removes the inflated product 700 that has been detected, and then recovers the gas in it to the air storage tank 100 through an air compressor.

[0091] The above actions are performed in sequence until the air leakage detection work of all inflated products 700 is completed.

[0092] Embodiment 2

[0093] The second embodiment has the same concept as the first embodiment. The difference is that the air leakage detection device in the second embodiment includes two test lines 600, that is, two test lines 600 are equipped with an air storage tank 100, an inflation device 200, a tester 300, and an electric control box 400. In addition, in this embodiment, each test line 600 includes a loading station 610, a testing station 620, and an unloading station 630. Among them, one or more than two test covers can be set at the testing station 620. When more than two test covers are set at the testing station 620, the loading station 610, the testing station 620, and the unloading station 630 of each test line 600 have the same structure as that in the first embodiment. When there is one test cover at the testing station 620, there is no loading lifting device 613 and unloading lifting device 632 at the loading station 610 and the unloading station 630, and other parts are the same as those in the first embodiment.

[0094] In this embodiment, the two test lines 600 are the first test line 601 and the second test line 602 respectively. The first test cover 6221 and the second test cover 6222 are provided on the testing station 620 of the first test line 601, and the third test cover 6223 and the fourth test cover 6224 are provided on the testing station 620 of the second test line 602. The working principle of air leakage detection in this embodiment is as follows:

[0095] In the two production lines, the operator at the loading station 610 only needs to be responsible for the inflation operation of the inflated product 700 and placing the inflated product 700 on the loading conveyor platform 611; while the operator at the unloading station 630 only needs to be responsible for removing the inflated product 700 that has completed the detection on the unloading conveyor platform 631 and recycling the gas in the inflated product 700 to the air storage tank 100 through an air compressor.

[0096] The controller will control the loading device 612 to cooperate with the loading lifting device 613 for automatic loading, and at the same time control the unloading lifting device 632 for unloading. The tester 300 also cyclically performs air leakage detection on the inflated products 700 in the first test cover 6221, the third test cover 6223, the second test cover 6222, and the fourth test cover 6224 in sequence under the control of the controller:

[0097] First, the controller controls the first-layer loading of the first test line 601 and the second test line 602: the inflated product 700 enters the bottom plate 6211 of the testing station 620, and the test lifting device 623 controls the first test cover 6221 and the third test cover 6223 to descend, respectively cooperating with the bottom plates 6211 of the first test line 601 and the second test line 602 to form a sealed test space. Then, the controller controls the tester 300 to perform air leakage detection on the inflated product 700 in the first test cover 6221. At the same time, the controller also controls the loading lifting devices 613 of the first test line 601 and the second test line 602 to rise to the second layer for second-layer loading.

[0098] After the inflatable product 700 in the first test cover 6221 has completed the leak detection (it may be during or after the second-layer loading), the tester 300 performs leak detection on the inflatable product 700 in the third test cover 6223. The controller controls the loading device 612 and the test lifting device 623 of the first test line 601 to perform the first-layer loading and unloading of the first test line 601.

[0099] After the inflatable product 700 in the third test cover 6223 has completed the leak detection, the tester 300 performs leak detection on the inflatable product 700 in the second test cover 6222. At the same time, the controller can control the loading device 612 and the test lifting device 623 of the second test line 602 to perform the first-layer loading and unloading of the second test line 602.

[0100] After the inflatable product 700 in the second test cover 6222 has completed the leak detection, the tester 300 performs leak detection on the inflatable product 700 in the fourth test cover 6224 in the store. At the same time, the controller controls the loading device 612, the loading lifting device 613, the unloading lifting device 632, and the test lifting device 623 of the first test line 601 to perform the second-layer loading and unloading of the first test line 601.

[0101] After the inflatable product 700 in the fourth test cover 6224 has completed the leak detection, the tester 300 performs leak detection on the inflatable product 700 in the first test cover 6221. At the same time, the controller controls the loading device 612, the loading lifting device 613, the unloading lifting device 632, and the test lifting device 623 of the second test line 602 to perform the second-layer loading and unloading of the second test line 602.

[0102] Repeat the above operations until the inflation detection of all inflatable products 700 is completed.

[0103] For the detection equipment in either Embodiment 1 or Embodiment 2, only operators need to be arranged at the loading station 610 and the unloading station 630. The operator at the loading station 610 only needs to be responsible for the inflation operation of the inflated product 700 and placing the inflated product 700 on the loading conveyor platform 611. The operator at the unloading station 630 only needs to be responsible for removing the inflated product 700 that has completed the detection on the unloading conveyor platform 631 and recovering the gas in the inflated product 700 to the air storage tank 100 through an air compressor. The loading, detection, and unloading of the production line can all be automated, thereby reducing the labor cost of leak detection for the inflated product 700. Moreover, since multiple test covers are provided on each test line 600 or two test lines 600 are provided in the present invention, the detection equipment can carry multiple inflated products 700 simultaneously, enabling the tester 300 to be responsible for the leak detection of multiple inflated products 700. When the tester 300 is detecting one inflated product 700, the loading and unloading operations of the remaining inflated products 700 can be carried out at the loading station 610 and the unloading station 630. Therefore, after the tester 300 completes the leak detection of one inflated product 700, it can directly perform the leak detection of the next inflated product 700 without waiting. Compared with the existing leak detection equipment, the present invention can reduce the waiting time for leak detection, thereby improving the leak detection efficiency.

[0104] For example, without considering the inflation time of the inflated product 700 (assuming the inflated product 700 has been inflated), the loading time is 15 seconds, and the leak detection time is 30 seconds. Then, according to the existing leak detection equipment, after the tester 300 finishes detecting one inflated product 700, it has to wait at least 15 seconds before starting the leak detection of the next inflated product 700. However, when using the leak detection equipment of the present invention, during the leak detection of one inflated product 700 by the tester 300, the next inflated product 700 has already been loaded. Therefore, after the tester 300 completes the leak detection of one inflated product 700, it can directly perform the leak detection of the next inflated product 700 without waiting. If 1000 inflated products 700 need to be leak-detected, according to the existing leak detection equipment, it will take at least 45000 seconds, while using the leak detection equipment of the present invention, it only takes 30015 seconds. It can be seen that for 1000 inflated products 700, using the leak detection equipment of the present invention saves nearly 15000 seconds (250 minutes).

[0105] The above description is only an embodiment of the present invention and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
