Description

Technical Field

[0001] The present invention relates to the technical field of inflatable wheel warehousing management, and particularly to an inflatable wheel warehousing management system. Background Art

[0002] The tire pressure of an inflatable wheel is an important factor affecting the safety performance of a vehicle. When the tire pressure is too low, it is easy to cause problems such as an increase in the deformation of the tire body of the inflatable wheel and cracks on the tire side. At the same time, it will also increase the contact area between the inflatable wheel and the ground and accelerate the wear of the tire shoulder. In order to ensure the quality and service life of the inflatable wheel, it is usually necessary to test the tire pressure of the inflatable wheel.

[0003] At present, usually the inflatable wheel is inflated on the parts manufacturing line, and then the tire pressure of the inflated inflatable wheel is measured manually by holding a tire pressure measuring instrument. Then, the inflatable wheels that pass the tire pressure test are stored in the warehouse centrally. When it is necessary to assemble the product, the inflatable wheel is taken out of the warehouse for testing and then assembled with the corresponding components to form the product. The method of manually measuring the tire pressure cannot track the information of each inflatable wheel. If the tire pressure of the inflatable wheel is insufficient before it is taken out of the warehouse for assembly or after it is assembled into the product and shipped out, it is also impossible to trace the tire pressure situation, production situation, etc. of the inflatable wheel before it is put into the warehouse or before it is assembled, and it is impossible to improve the inflatable wheel according to the problems that occur to the inflatable wheel. Summary of the Invention

[0004] The purpose of the present invention is to provide an inflatable wheel warehousing management system that can track the information of inflatable wheels.

[0005] To achieve the above purpose, the present invention discloses an inflatable wheel warehousing management system for measuring the tire pressure of an inflatable wheel before it is put into the warehouse and after it is taken out of the warehouse and managing the information of the inflatable wheel, including a tire pressure detection device and a processing device. The tire pressure detection device is used to detect the tire pressure of the inflated inflatable wheel before it is put into the warehouse to obtain a first pressure value and send the information of the inflatable wheel whose first pressure value reaches a first preset value and the corresponding first pressure value to the processing device for storage; the tire pressure detection device is further used to detect the tire pressure of the inflatable wheel after it is taken out of the warehouse to obtain a second pressure value and send the information of the product assembled with the inflatable wheel whose second pressure value reaches a second preset value and the corresponding second pressure value to the processing device for storage.

[0006] The present invention is provided with a processing device, which stores the first pressure value, the information of the inflatable wheel, the second pressure value and the information of the product assembled with the inflatable wheel sent by the tire pressure detection device, realizing the information tracking of the inflatable wheel and the product assembled with the inflatable wheel, facilitating later query; further, the yield rate of the inflatable wheel can also be statistically calculated according to the information stored in the processing device, so as to improve the inflatable wheel according to the statistical result, thereby reducing the repair rate of the inflatable wheel and improving the production efficiency.

The processing device calculates the number of pneumatic wheels in each batch number whose second pressure value reaches the second preset value to obtain the number of qualified products, and obtains the qualification rate of the pneumatic wheels in each batch number based on the number of qualified products.

[0008] Preferably, the tire pressure detection device also sends the information of the pneumatic wheel with the second pressure value lower than the second preset value and the corresponding second pressure value to the processing device for storage. Thereby, the tire pressure tracking of each pneumatic wheel shipped from the warehouse is realized.

[0009] More preferably, the information of the pneumatic wheel includes the identification of the pneumatic wheel. The processing device compares the first pressure value and the second pressure value of the pneumatic wheel corresponding to each identification to obtain the pressure difference.

[0012] Preferably, the information of the pneumatic wheel includes the production date, inflation date and batch number of the pneumatic wheel. Thereby, the pneumatic wheels of the manufacturer can be reviewed according to the qualification rate of each batch number to find out the problems of the pneumatic wheels.

[0013] Preferably, the information of the product includes the product assembly date and assembly batch number.

[0014] Preferably, the tire pressure detection device is provided with an alarm. When the first pressure value is lower than the first preset value or the second pressure value is lower than the second preset value, the tire pressure detection device outputs an alarm signal to make the alarm sound.

[0020] To describe in detail the technical content, structural features, and achieved effects of the present invention, the following is described in detail in conjunction with the embodiments and with reference to the accompanying drawings.

[0021] Please refer to Figure 1 and Figure 2 , the pneumatic wheel storage management system 100 of the present invention is used to measure the tire pressure of the pneumatic wheel 200 before and after warehousing to ensure that the tire pressure of the pneumatic wheel 200 before warehousing and the tire pressure for assembly are qualified, and to store the tire pressure information and its related information of the pneumatic wheel 200 with qualified tire pressure before warehousing to achieve information tracking of the pneumatic wheel 200, so as to facilitate querying the information of the pneumatic wheel 200 later and performing yield statistics, performance evaluation, etc. of the pneumatic wheel 200 according to the stored information of the pneumatic wheel 200. Specifically, the pneumatic wheel storage management system 100 of the present invention includes a tire pressure detection device and a processing device 3. The tire pressure detection device is used to detect the tire pressure of the inflated pneumatic wheel 200 before warehousing to obtain a first pressure value and send the information of the pneumatic wheel 200 whose first pressure value reaches the first preset value and the corresponding first pressure value to the processing device 3 for storage; the tire pressure detection device is further used to detect the tire pressure of the pneumatic wheel 200 after warehousing to obtain a second pressure value and send the information of the product (not shown in the figure) assembled with the pneumatic wheel 200 whose second pressure value reaches the second preset value and the corresponding second pressure value to the processing device 3 for storage.

[0022] Specifically, the first preset value and the second preset value are values set according to actual tire pressure requirements. The first preset value and the second preset value can be the same value, or the first preset value can be slightly larger than the second preset value. The processing device 3 can be any device capable of realizing data storage and processing.

[0023] Hereinafter, for convenience of description, when the tire pressure detection device is used to detect the inflated wheel 200 after inflation before the inflated wheel 200 is stored in the warehouse, it is denoted as the first tire pressure detection device 1, and when the tire pressure detection device is used to detect the tire pressure of the inflated wheel 200 after it is out of the warehouse, it is denoted as the second tire pressure detection device 2. In this embodiment, the first tire pressure detection device 1 is arranged on the part manufacturing line, and the second tire pressure detection device 2 is arranged on the assembly line. Specifically, after the inflated wheel 200 is inflated on the part manufacturing line, the first tire pressure detection device 1 detects the tire pressure of the inflated wheel 200 to obtain a first pressure value, and then sends the first pressure value and the information of the inflated wheel 200 to the processing device 3, and transports the inflated wheel 200 with the first pressure value reaching the first preset value to the warehouse for storage through the handling device. Before assembling the inflated wheel 200 after it is out of the warehouse, the second tire pressure detection device 2 detects the tire pressure of the inflated wheel 200 after it is out of the warehouse to obtain a second pressure value, and then sends the second pressure value and the information of the product to the processing device 3, and assembles the inflated wheel 200 with the second pressure value reaching the second preset value with the corresponding components to obtain the product.

[0024] Among them, the first tire pressure detection device 1 and the second tire pressure detection device 2 can be two separate tire pressure detection devices, or the same tire pressure detection device, as long as they can detect the tire pressure of the inflated wheel before and after it is stored in the warehouse. Of course, the first tire pressure detection device 1 and the second tire pressure detection device 2 are not limited to being installed on the part manufacturing line and the assembly line, and can also be installed at any other position.

[0025] In one embodiment, the information of the inflated wheel 200 includes the production date, inflation date and batch number of the inflated wheel 200; among them, the batch number of the inflated wheel 200 is the purchase batch number. The production situation of the inflated wheel 200 can be traced through the production date, inflation date and batch number of the inflated wheel 200, so as to improve the performance of the inflated wheel 200 according to the tire pressure situation and the production situation. Of course, in other embodiments, the information of the inflated wheel 200 can also include other information, such as the manufacturer and model information of the inflated wheel 200, etc., so it should not be limited to this.

[0026] In one embodiment, the information of the product includes the assembly date and assembly batch number; thereby, the assembly situation of the product can be traced through the assembly date and assembly batch number. Of course, in other embodiments, the information of the product can also include other information, so it should not be limited to this.

[0027] As a preferred embodiment, the information of the inflatable wheel 200 includes the batch number of the inflatable wheel 200. The processing device 3 calculates the number of qualified inflatable wheels 200 in each batch number where the second pressure value reaches the second preset value to obtain the number of qualified products, and obtains the yield rate of the inflatable wheels 200 in each batch number based on the number of qualified products. Thereby, the inflatable wheels 200 of the manufacturer can be reviewed according to the yield rate of each batch number to find out the problems of the inflatable wheels 200, so as to obtain inflatable wheels 200 with excellent performance, and further reduce the ratio of inflatable wheels 200 that need to be repaired and improve production efficiency.

[0028] Specifically, the processing device 3 obtains the yield rate of the inflatable wheels 200 in each batch number based on the number of qualified products obtained when the first tire pressure detection device 1 detects the inflatable wheels 200 in each batch number and the number of qualified products obtained when the second tire pressure detection device 2 detects the inflatable wheels 200 in each batch number.

[0029] As a preferred embodiment, the second tire pressure detection device 2 also sends the information of the inflatable wheels 200 with the second pressure value lower than the second preset value and the corresponding second pressure value to the processing device 3 for storage. Thereby, the tire pressure tracking of each inflatable wheel 200 shipped from the warehouse is realized.

[0030] Furthermore, the information of the inflatable wheel 200 includes the identifier of the inflatable wheel 200. The processing device 3 compares the first pressure value and the second pressure value of the inflatable wheel 200 corresponding to each identifier to obtain the pressure difference. Through the pressure difference, the performance of each inflatable wheel 200 is evaluated; for example, the larger the pressure difference, the worse the performance of the inflatable wheel 200, and vice versa, it means that the performance of the inflatable wheel 200 is better.

[0031] Even further, the information of the inflatable wheel 200 includes the inflation date. The processing device 3 obtains the storage days of the inflatable wheel 200 based on the inflation date and the current time, and evaluates the performance of each inflatable wheel 200 based on the storage days and the pressure difference. Specifically, a functional relationship including the storage days of the inflatable wheel 200 and the tire pressure change of the inflatable wheel 200 can be established, and the performance of the inflatable wheel 200 is evaluated according to this functional relationship and the obtained pressure difference.

[0032] As a preferred embodiment, the processing device 3 divides into several pressure intervals according to the magnitude of the pressure value of the inflatable wheel 200, calculates the number of inflatable wheels 200 in each pressure interval, and obtains the ratio of the inflatable wheels 200 in each pressure interval based on the number of inflatable wheels 200 in each pressure interval. Thereby, the tire pressure information of the inflatable wheel 200 is made more intuitive and convenient to view. Preferably, the processing device 3 also outputs a bar chart and a line chart of the tire pressure of the inflatable wheel 200 according to the ratio of the inflatable wheels 200 in each pressure interval.

[0033] Please refer to Figure 2, as a preferred embodiment, the tire pressure detection device is provided with an alarm 11. When the first pressure value is lower than the first preset value or the second pressure value is lower than the second preset value, the tire pressure detection device outputs an alarm signal to make the alarm 11 alarm. With this design, the on-site staff can timely obtain the tire pressure monitoring result, so as to perform corresponding processing on the under-inflated inflatable wheel 200. Preferably, the alarm 11 is a light alarm, and the alarm 11 lights up to alarm when the tire pressure of the inflatable wheel 200 is insufficient; of course, the alarm 11 can also be other alarms, such as a voice alarm, etc.

[0034] Please refer to Figure 2 , specifically, the tire pressure detection device includes a positioning mechanism 12, a measuring mechanism 13, and a display 14 electrically connected to the measuring mechanism 13.

[0035] Specifically, the measuring mechanism 13 includes a nozzle 131, a driver 132 for driving the nozzle 131 to measure the tire pressure, and a barometer (not shown in the figure). A gas guiding channel (not shown in the figure) is provided in the nozzle 131, and the gas guiding channel is communicated with the barometer. The gas in the inflatable wheel 200 enters through the gas guiding channel and then reaches the barometer, so as to measure the tire pressure of the inflatable wheel 200 through the barometer to obtain the first pressure value and the second pressure value. The barometer then transmits the first pressure value and the second pressure value to the processing module of the tire pressure detection device to compare the first pressure value with the first preset value and the second pressure value with the second preset value, and the first pressure value and the second pressure value are displayed via the display 14.

[0036] As a preferred embodiment, the positioning mechanism 12 is provided with an insertion portion 121, and the insertion portion 121 is for the wheel axle 210 of the inflatable wheel 200 to be inserted to position the inflatable wheel 200. Preferably, the insertion portion 121 is provided with a jack 1211 adapted to the wheel axle 210 of the inflatable wheel 200, and the inflatable wheel 200 is stably positioned through the jack 1211, but it should not be limited thereto.

Of course, in some embodiments, the display 14 can also include a display screen and an input keyboard. The information of the inflatable wheel 200 is input through the input keyboard, and the first pressure value, the second pressure value, and the information of the inflatable wheel 200 are displayed through the display screen, so it should not be limited thereto.

[0038] Please continue to refer to Figure 2, as a preferred embodiment, the pneumatic wheel warehousing management system 100 further includes a control device 4 and a manipulator 5.

By means of the control device 4 and the manipulator 5, the unloaded pneumatic wheel 200 after detection is placed at the corresponding position, reducing manual participation and saving labor costs.

[0039] Specifically, the control device 4 controls the manipulator 5 to place the pneumatic wheel 200 with the comparison result that the first pressure value reaches the first preset value (qualified tire pressure) at the first position, and place the pneumatic wheel 200 with the comparison result that the first pressure value is lower than the first preset value (insufficient tire pressure) at the second position; the control device 4 controls the manipulator 5 to place the pneumatic wheel 200 with the comparison result that the second pressure value reaches the second preset value (qualified tire pressure) at the third position, and place the pneumatic wheel 200 with the comparison result that the second pressure value is lower than the second preset value (insufficient tire pressure) at the fourth position.
