[0002] The real-time tire pressure monitoring system is mainly used to automatically monitor the tire pressure in real time while the car is driving, and to alarm for tire leakage and low pressure. With the gradual improvement of automobile safety performance requirements, tire pressure monitoring has gradually become standard equipment from passenger cars to commercial vehicles. Almost every car has a tire pressure sensor to detect the tire pressure at any time, and even has an alarm function to reduce the risk of tire accidents, which is very popular among people.

DETAILED DESCRIPTION

[0040] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0041] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0042] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] In one embodiment, a testing system for a tire pressure sensor is described, which can automatically test the tire pressure sensor by setting a sampling unit 1, a testing unit 2, a loading unit 3 and a unloading unit 4, thereby reducing labor costs and equipment costs, and can effectively improve the detection efficiency of the tire pressure sensor, and the accuracy and reliability are also improved.

[0045] Specifically, see the accompanying drawings Figures 1 to 5 A testing system for a tire pressure sensor includes a sampling unit 1, a testing unit 2, a loading unit 3 and a unloading unit 4 arranged on the side of the sampling unit 1, wherein the testing unit 2 is used to detect the product to be tested (tire pressure sensor) to obtain qualified products and unqualified products in the product to be tested. Correspondingly, the loading unit 3 and the unloading unit 4 each include a support frame 51 and a transfer module 53, wherein the transfer module 53 is movably arranged on the support frame 51. In addition, a first station 511 and a second station 512 are arranged in the support frame 51, and the transfer module 53 can reciprocate between the first station 511 and the second station 512. At least one carrying module 52 is also arranged at the first station 511, which is suitable for placing the product (tire pressure sensor). When the transfer module 53 moves between the first station 511 and the second station 512, it can transfer the carrying module 52 at the first station 511 to the second station 512.

[0046] Furthermore, the sampling unit 1 is used to deliver the product to be tested on the carrier module 52 of the first station 511 on the loading unit 3 to the testing unit 2, and the product is tested by the testing unit 2 to see if it is qualified. After the product on a carrier module 52 is completely taken out, the transfer module 53 of the loading unit 3 transfers an empty carrier module 52 to the second station 512 of the loading unit 3. Correspondingly, the sampling unit 1 is also used to transfer the qualified product after being tested by the testing unit 2 to the carrier module 52 of the unloading unit 4. After a carrier module 52 is filled with qualified products, the transfer module 53 of the unloading unit 4 transfers the carrier module 52 and the qualified products to the second station 512 of the unloading unit 4.

[0047] It is understandable that in the prior art, the testing of tire pressure sensors is mostly done by workers manually placing the tire pressure sensors in the testing equipment to complete the testing of temperature, air pressure and other items. This process is complicated and cumbersome, requires the use of a large amount of equipment, and requires workers to constantly manually take the tire pressure sensors, which has high manpower and material costs, and manual operation is prone to errors and unnecessary losses.

[0048] In this embodiment, during operation, the staff only needs to stack the tire pressure sensor on the carrier module 52 of the loading unit 3, and the sampling unit 1 transfers the carrier module 52 on the loading unit 3 to the testing unit 2. The testing unit 2 tests the product to be tested. If the product is qualified, the sampling unit 1 transfers the qualified product to the carrier module 52 of the unloading unit 4, and so on, until all the products of a carrier module 52 of the loading unit 3 are taken out. After all the products of a carrier module 52 of the loading unit 3 are taken out, the transfer module 53 transfers an empty carrier module 52 (a single carrier module 52) to the second station 512, and the sampling unit 1 continues to transfer the products to be tested on the subsequent carrier modules 52 to the testing unit 2. In addition, after a carrier module 52 of the unloading unit 4 is filled with qualified products, the transfer module 53 transfers the carrier module 52 and the qualified products to the second station 512, and the sampling unit 1 continues to transfer the subsequent qualified products to the carrier module 52 at the first station 511 of the unloading unit 4. It can be seen that the transportation of the product of the present application can be completed through the sampling unit 1 and the transportation module 53. Through the cooperation between the two, batch detection of tire pressure sensors can be achieved, with high work efficiency, fast speed, and higher test accuracy and reliability.

[0049] In addition, it should be pointed out that the number of the carrier modules 52 at the first station 511 can be set according to actual needs, for example, only one can be set, and when a carrier module 52 is transferred to the second station 512, the staff can manually place the next carrier module 52 at the first station 511. Of course, multiple carrier modules 52 can be set. This does not require the staff to take the carrier modules 52 multiple times, and the work efficiency is higher.

[0050] In one embodiment, referring to the accompanying drawings, Figures 1 to 3 , this embodiment further describes the support frame 51. The support frame 51 further includes a first lifting mechanism 54, which is disposed in the first station 511. Correspondingly, the bearing modules 52 of the loading unit 3 and the unloading unit 4 are respectively disposed on the first lifting mechanism 54, and the first lifting mechanism 54 is used to drive the bearing module 52 to move up and down, thereby driving the product to move up and down.

[0051] It can be understood that the setting of the first lifting mechanism 54 can enable multiple carrier modules 52 to be placed in the first station 511, and can improve the continuous working time of the test system for tire pressure sensors. During operation, multiple carrier modules 52 are placed on the first lifting mechanism 54. After the product to be tested of a carrier module 52 of the loading unit 3 is completely transferred to the test unit 2, the transfer module 53 transfers the empty carrier module 52 to the second station 512, and then the first lifting mechanism 54 rises, driving the remaining carrier modules 52 to move upward, so that the next carrier module 52 can be located within the working range of the transfer module 53, so that the product to be tested can be continuously transferred to the test unit 2. Similarly, after the sampling unit 1 transfers a full carrier module 52 with qualified products, the transfer module 53 transfers the carrier module 52 and the qualified products to the second station 512, and then the first lifting mechanism 54 rises, driving the remaining carrier modules 52 to move upward, so that the next carrier module 52 can be located within the working range of the transfer module 53, so that the qualified products can be continuously transferred to the carrier module 52.

[0052] Furthermore, the support frame 51 also includes a second lifting mechanism 55, which is located in the second workstation 512. The second lifting mechanism 55 is used to receive the carrying module transferred by the transfer module 53, and is used to drive the carrying module 52 to move up and down.

[0053] It can be understood that the second lifting mechanism 55 is used to place the carrying module 52. When the transfer module 53 of the loading unit 3 drives the empty carrying module 52 to move to the second station 512, the second lifting mechanism 55 rises to receive the empty carrying module 52. Similarly, when the transfer module 53 of the unloading unit 4 drives the carrying module 52 and qualified products to move to the second station 512, the second lifting mechanism 55 rises to receive the carrying module 52 and qualified products.

[0054] In actual production applications, the first lifting mechanism 54 and the second lifting mechanism 55 can use screw transmission, linear motor drive, etc. to drive the supporting module 52 to move up and down, or other structures can be used to achieve this purpose. They are not explained here one by one and are all within the protection scope of the present utility model.

[0055] In one embodiment, referring to the accompanying drawings, Figure 3, this embodiment further describes the transfer module 53, wherein the transfer module includes a sliding frame 531, a first driving member 532, a second driving member, a mounting plate 534 and a plurality of first adsorption members 533 disposed on the mounting plate 534. The sliding frame 531 is movably disposed on the support frame 51, and the sliding frame 531 is driven by the second driving member to move relative to the support frame 51. In addition, the mounting plate 534 is disposed in the sliding frame 531, and the first driving member 532 is disposed on the sliding frame 531 and is in transmission connection with the mounting plate 534, so as to drive the mounting plate 534 to move up and down, so as to adjust the distance between the first adsorption members 533 and the supporting module 52.

[0056] It can be understood that the first driving member 532 drives the mounting plate 534 to move up and down, thereby driving the first adsorption member 533 to move up and down. When the first adsorption member 533 contacts the carrying module 52, it can drive the carrying module 52 to move together, so as to facilitate the transfer of the carrying module 52 to the second workstation 512.

[0057] The first adsorption component 533 is used to fix the carrier module 52 by vacuum adsorption. In actual production applications, the transfer module 53 can also use other mechanisms to transport the carrier module 52, for example, using clamps or magnetic suction, etc., which are not explained here one by one and are all within the protection scope of the present utility model.

[0058] In one embodiment, referring to the accompanying drawings, Figure 1 The present embodiment further describes the sampling unit 1. The sampling unit 1 includes a stand 11 and a mechanical arm 12. The mechanical arm 12 is disposed on the stand 11. The mechanical arm 12 is used to transfer the product to be tested of the loading unit 3 to the testing unit 2, and is also used to transfer the qualified product to the carrying module 52 of the unloading unit 4.

[0059] Correspondingly, a storage area 13 is also provided on the stand 11 , and the robotic arm 12 can also transfer unqualified products tested by the testing unit 2 to the storage area 13 .

[0060] In one embodiment, each support frame 51 is provided with a first station 511 and a second station. Accordingly, at this time, the sampling unit 1 has one mechanical arm 12, and the testing unit 2 is also provided with one mechanical arm 12, and one mechanical arm 12 is used to take the product of the loading unit 3. In this way, one mechanical arm 12 takes the product to be tested on the loading unit 3, and after the product is tested by the testing unit 2, the qualified product is transferred to the unloading unit 4 by the mechanical arm 12.

[0061] In addition, in order to improve the working efficiency of the test system for the tire pressure sensor, in this embodiment, each support frame 51 is provided with two first stations 511, and one second station 512, and the two first stations 511 are respectively provided on both sides of the second station 512. Accordingly, each first station 511 of the feeding unit 3 is provided with a corresponding mechanical arm 12, that is, the sampling unit 1 is provided with two mechanical arms 12, the test unit 2 is provided with two, and the two test units 2 are provided with the corresponding mechanical arms 12.

[0062] It can be understood that, in this embodiment, each robotic arm 12 is used to transfer products on a first station 511 of the loading unit 3 to a testing unit 2, and the robotic arm 12 then transfers qualified products to a first station 511 of the unloading unit 4.

[0063] Furthermore, the loading unit 3 and the unloading unit 4 are relatively arranged at the two ends of the extension direction of the stand 11, and the two test units 2 are relatively arranged at the two ends perpendicular to the extension direction of the stand 11, that is, the loading unit 3, the test unit 2, the unloading unit 4 and the test unit 2 are arranged in sequence along the circumference of the stand 11.

[0064] It is understandable that the number of the first workstations 511 and the second workstations 512 on each support frame 51 can be set according to actual needs, which are not described one by one here and are all within the protection scope of the present utility model.

[0065] In addition, the robot arm 12 includes an arm body and a second adsorbent 121 disposed on the arm body, and two second adsorbents 121 are provided, and the two second adsorbents 121 are disposed at one end of the arm body, and the other end of the arm body is fixed on the stand 11. One second adsorbent 121 is used to adsorb the product tested by the test unit 2, and the other is used to adsorb the product to be tested on the loading unit 3.

[0066] Preferably, each second adsorption member 121 is also provided with a telescopic member for adjusting the extension length of each second adsorption member 121 to increase the working range of the second adsorption member 121. In addition, the robot arm 12 can use a multi-axis robot arm, and the robot arm 12 can also move relative to the stand 11 to further increase the flexibility of the robot arm 12. When the first station 511 is set to two, the number of the robot arms 12 can also be determined according to the time it takes for the test unit 2 to test a product. If the time for testing a product is relatively long, the robot arm 12 can be set to one, and it can also complete the work of taking the products to be tested at the two first stations 511.

[0067] In one embodiment, a test system for a tire pressure sensor further includes a first camera module 6 arranged in one-to-one correspondence with the first station 511, and the first camera module 6 is arranged above the first station 511. In addition, the carrying module 52 is arranged as a tray, and each of the trays is provided with a plurality of mounting slots for placing products. The first camera module is used to take a picture of the first station 511 to obtain the number of the products in the tray.

[0068] Furthermore, the test unit 2 includes a second camera module 21 and at least one test box 22. The second camera module 21 is used to obtain the position information of the product on the robot arm 12. The test box 22 is used to receive the product on the robot arm 12 and test the product. In addition, a pressure regulating module and a temperature regulating module are provided in the test box 22 to adjust the temperature and pressure in the test box 22 to simulate the working environment of the tire pressure sensor, and then test the tire pressure sensor.

[0069] See the attached drawings in the specification Figure 6 The test box 22 is provided with an opening, and an upper cover is provided at the opening to control the opening to be opened or closed by a driving mechanism. A positioning fixture for placing the product is provided in the test box 22, and a pressure sensor and a temperature sensor are provided in the test box 22. When in use, the driving mechanism controls the upper cover to open the opening, and the robot arm 12 puts the product to be tested into the test box 22, and then the driving mechanism controls the upper cover to close the opening, and the pressure regulating module and the temperature regulating module in the test box are adjusted to the predetermined air pressure and temperature, and the data of the pressure sensor and the temperature sensor are compared with the data of the product (tire pressure sensor) to determine whether the product is qualified.

[0070] A test system for a tire pressure sensor also includes a control component 7, which is electrically connected to a sampling unit 1, a loading unit 3, a unloading unit 4, a first camera module 6, and a second camera module 21. The control component 7 is used to control the sampling unit 1 to take a product, and control the test unit 2 to detect the product. Moreover, the control component 7 is electrically connected to the first camera module 6 and the second camera module 21. The control component 7 obtains the number of products on the carrier module 52 at the first station 511 through the first camera module 6. For example, after the products of a carrier module 52 of the loading unit 3 are transferred, or after a carrier module 52 of the unloading unit 4 is full of qualified products, the control component 7 controls the transfer module 53 to transfer the carrier module 52 to the second station 512. The control component 7 can determine the positional relationship of the product relative to the test box 22 according to the position information of the product on the mechanical arm 12 obtained by the second camera module 21. If there is a deviation in the position, the control component 7 can control the mechanical arm 12 to adjust the position of the product so as to put the product into the test box 22.

[0071] Furthermore, a test system for a tire pressure sensor further includes a cabinet 8, a three-color light 81, a display screen 82 and a control screen 84. The sampling unit 1, the test unit 2, the loading unit 3 and the unloading unit 4 are all arranged in the cabinet 8, and the three-color light 81, the display screen 82 and the control screen 84 are all arranged on the cabinet. Correspondingly, a cabinet door 83 that can be opened or closed is also arranged on the cabinet 8, and the cabinet door 83 is arranged relative to the loading unit 3.

[0072] It is understandable that the cabinet door 83 is provided so that the cabinet 8 can be opened to facilitate the staff to take the tested products. The control panel 84 is electrically connected to the control component 7 and is used to control the opening or closing of the test system. In addition, the display screen 82 is used to display production information, such as the type of tested products, the progress of the test, the qualified product rate and other information.
