[0002] Wheel speed sensors are used to measure the rotational speed of a vehicle's wheels. Wheel speed information is essential for vehicles, including the Vehicle Dynamic Control (VDC), Electronic Stability Program (ESP), and Anti-lock Brake System (ABS). Therefore, wheel speed sensors are among the most critical sensors in a vehicle.

[0003] Currently, the performance of wheel speed sensors can only be tested using independent positioning column cutting equipment to cut the positioning columns of the injection molded body, and workers manually install O-rings, resulting in low production efficiency. Visual inspection is used to confirm whether the traceability mark is engraved, and OK products that meet performance requirements and NG products that do not meet performance requirements also need to be manually sorted and processed, posing the risk of unmarked sensors flowing out and NG products being circulated and used.

[0051] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0052] refer to Figures 1 to 15The present application provides a performance detection device for detecting the performance of a sensor 1, comprising: a conveying unit 10 and a plurality of workstations, wherein the plurality of workstations are arranged in sequence along the conveying direction of the conveying unit 10, the conveying unit 10 comprises a plurality of molds 20 corresponding to the number of the plurality of workstations, each mold 20 is used to accommodate the sensor 1, and the conveying unit 10 is used to drive each mold 20 to move between the plurality of workstations; and a loading unit 30, a cutting unit 40, a testing unit 50, an installation unit 80, a verification unit 90 and a unloading unit corresponding to at least part of the plurality of workstations.

[0053] For example, Figure 12 As shown in FIG, the conveying unit 10 includes a turntable 101, but is not limited thereto. The embodiment of the present application does not impose any specific limitation on the structure of the conveying unit 10. For example, the conveying unit 10 may also be a conveyor belt.

[0054] It should be noted that if Figure 3 As shown in , the number of multiple workstations in the embodiment of the present application is ten, that is, the number of multiple molds 20 is ten, but the present application does not impose specific restrictions on the number of workstations and the molds 20 corresponding to the number of workstations. It can be set according to actual conditions, as long as at least one mold 20 is provided at each workstation in the performance testing device of the embodiment of the present application.

[0055] Specifically, the embodiment of the present application (the performance testing system described below) further includes a control unit (not shown in the figure), which is connected to the performance testing device. Specifically, the conveying unit 10, the loading unit 30, the cutting unit 40, the testing unit 50, the installation unit 80, the calibration unit 90, and the unloading unit are each connected to the control unit, which is used to control the conveying unit 10 to transport each mold 20 to the next station.

[0056] Continue to refer Figure 3 The first conveying portion 301 is provided at one end 3042 of the loading unit 30. The first conveying portion 301 includes a second gripping portion and is adjacent to the conveying unit 10. The second gripping portion is used to grip the sensor 1 and convey the sensor 1 from the one end 3042 of the loading unit 30 to the mold 20 located at the corresponding station of the loading unit 30.

[0057] It should be noted that each corresponding station on the conveying unit 10 is provided with a mold 20, each mold 20 is fixedly connected to the conveying unit 10, and is driven by the conveying unit 10 along the conveying direction (such as Figure 3 The sensor 1 is sequentially moved between the corresponding workstations (indicated by the R direction in the figure). The loading unit 30, via the second gripping portion of the first conveying portion 301, grips the sensor 1 from one end 3042 of the loading unit 30 and conveys it to the mold 20 located on the conveying unit 10. This allows for multi-step testing of the sensor 1, thus achieving automatic loading of the sensor 1.

[0058] refer to Figure 7 (a) and (b) and Figure 8 Combine (a) and (b) Figure 1 The cutting unit 40 includes a second driving portion 401 and a cutting piece 402. The second driving portion 401 can drive the cutting piece 402 to move in a third direction (eg Figure 7 (shown in the Z direction) up and down movement. Figure 15 The mounting unit 80 includes a third driving portion 801 and a mounting portion 803. The mounting portion 803 includes a third clamping portion and a sealing member 13. The third clamping portion is used to clamp the sealing member 13 and transport the sealing member 13 to the mold 20 located at the corresponding station of the mounting unit 80. The third driving portion 801 can drive the mounting portion 803 to move up and down along the third direction. For example, the third direction intersects with the transport direction, but is not limited thereto. Figure 1 , the third direction is perpendicular to the conveying direction.

[0059] refer to Figure 13 Combined with Figure 7 (a) and (b) and Figure 8 In (a) and (b), the sensor 1 has a positioning bracket 11 and a groove 12, and the second driving part 401 is used to drive the cutting member 402 along the third direction (such as Figure 13 The Z direction is shown in FIG. 1 ) and moves downward to cut and position the bracket 11. Figure 15 The mounting portion 803 has a sealing member 13, and the third driving portion 801 is used to drive the mounting portion 803 along a third direction (such as Figure 15 The mounting unit 80 moves downward (as shown in the Z direction) so that the sealing member 13 is accommodated in the groove 12 , that is, the mounting unit 80 is used to mount the sealing member 13 on the sensor 1 .

[0060] refer to Figure 10 and Figure 11 Combined with Figure 1 and Figure 3 The test unit 50 includes a ring gear, which is communicatively connected to the sensor 1 of the mold 20 accommodated in the corresponding station of the test unit 50. When the test unit 50 tests the sensor 1, each sensor 1 is used to detect the wheel speed of the ring gear and send the detected wheel speed signal to an external receiving component (such as the above-mentioned control unit), so that the sensor 1 is divided into a first type sensor and a second type sensor according to the wheel speed signal.

[0061] refer to Figure 9 Combined with Figure 1The verification unit 90 includes an image acquisition part, which is directed toward the first type sensor of the mold 20 accommodated in the corresponding workstation of the verification unit 90, and sends the acquired image signal to the receiving component (for example, the above-mentioned control part), so that the first type sensor is divided into a third type sensor and a fourth type sensor according to the image signal.

[0062] refer to Figure 5 and Figure 6 A second conveying part 601 is provided at one end of the blanking unit, and a blanking box 602 is provided at the other end. The second conveying part 601 includes a first clamping part, which is used to clamp the target type sensor 1 and transport the sensor 1 from the mold 20 of the corresponding station of the blanking unit to the blanking box 602.

[0063] It should be noted that the target class sensors 1 mentioned above refer to the first, second, third, and fourth class sensors mentioned above. That is, the unloading unit is configured to clamp the aforementioned various sensors and convey them to the corresponding unloading box 602 (the clamping and conveying process of the unloading unit will be described in detail later).

[0064] In summary, the performance testing device of the embodiment of the present application can integrate other processes that require manual operation into the performance testing process. That is, the second gripping portion of the loading unit 30 grips and conveys the sensor 1 to be tested to the conveying unit 10, and the conveying unit 10 sequentially conveys the sensor 1 to the subsequent workstation. The cutting member 402 of the cutting unit 40 cuts the positioning bracket 11 of the sensor 1. The performance of the sensor 1 is tested by having the sensor 1 at the corresponding workstation collect the wheel speed signal of the ring gear of the testing unit 50. The sealing member 13 is installed in the groove 12 of the sensor 1 by the mounting portion 803 of the mounting unit 80. The image acquisition portion of the verification unit collects the image signal of the sensor at the corresponding workstation and verifies the seal on the sensor and / or the mark engraved by the marking unit 70 described later. The unloading unit then loads the sensors 1 that meet the requirements (i.e., the first and third type sensors) and the sensors 1 that do not meet the requirements (i.e., the second and fourth type sensors) into the unloading box 602. This improves the efficiency and accuracy of performance testing and reduces interference from human factors.

[0065] In some possible implementations, reference Figure 4 Combined with Figure 1 , further comprising a marking unit 70, along the conveying direction (such as Figure 1 The marking unit 70 is provided at the upper station of the corresponding station of the mounting unit 80, and the marking unit 70 includes a marking portion 701, along the first direction (as shown in FIG. Figure 1 and Figure 4The marking unit 701 is arranged toward the mold 20 corresponding to the station of the marking unit 70, and the marking unit 70 is used to engrave the marking information on the first type sensor accommodated in the mold 20. For example, Figure 1 As shown in , the first direction and the third direction (as Figure 1 The Z direction is perpendicular to the center.

[0066] In some possible implementations, continue to refer to Figure 5 and Figure 6 Combined with Figure 1 The unloading unit includes a first unloading unit 61 and a second unloading unit 62, and the unloading box 602 includes a first unloading box 6021 and a second unloading box 6022. The first unloading unit 61 is located at the next station of the corresponding station of the testing unit 50, and is used to accommodate the second type of sensor in the first unloading box 6021 via the second conveyor. The second unloading unit 62 is located at the next station of the corresponding station of the verification unit 90, and is used to accommodate the third type of sensor and the fourth type of sensor in the second unloading box 6022 via the second conveyor.

[0067] Thus, the second type of sensors that do not meet the performance test requirements can be accommodated in the first blanking box 6021, and the third type of sensors and the fourth type of sensors that meet the performance test requirements can be accommodated in the second blanking box 6022, that is, the second type of sensors and the first type of sensors can be accommodated in different blanking boxes 602 respectively, so as to reduce the risk of NG sensors (i.e., second type of sensors) that do not meet the requirements being circulated and used.

[0068] In some possible implementations, continue to refer to Figure 7 (a) and (b) and Figure 8 Combine (a) and (b) Figure 1 The cutting unit 40 includes a first cutting unit 41 and a second cutting unit 42. The second cutting unit 42 is provided at the next station corresponding to the first cutting unit 41. The cutting piece 402 includes a first cutting piece 4021 and a second cutting piece 4022. The first cutting piece 4021 is provided at the first cutting unit 41. The second driving part 401 is used to drive the first cutting piece 4021 to move along the third direction (such as Figure 7 and Figure 8 The second cutting member 4022 is provided in the second cutting unit 42, and the second driving portion 401 is used to drive the second cutting member 4022 to move downward along the third direction to cut the remaining positioning bracket 11.

[0069] Thus, the positioning bracket 11 of the same sensor 1 can be cut sequentially by the first cutting unit 41 and the second cutting unit 42 at adjacent stations to achieve a better cutting effect. For example, a two-step cutting process of first rough cutting and then fine cutting can be used, but this is not limited to this. The present application does not impose any restrictions on the number and specific structure of the cutting units 40, as long as the positioning bracket 11 of the sensor 1 can be removed.

[0070] In some possible implementations, continue to refer to Figure 2 Combined with Figure 1 and Figure 3 The loading unit 30 further includes a loading mold 302 and a first driving part 303.

[0071] Thus, the second clamping part can sequentially clamp the multiple sensors 1 in the loading mold 302 and convey them to the mold 20 corresponding to the workstation of the loading unit 30 in the conveying unit 10, thereby realizing automatic loading of the performance detection device and improving the efficiency of the performance detection work.

[0072] In some possible implementations, continue to refer to Figure 15 Combined with Figure 1 and Figure 13 The installation unit 80 further includes a fourth driving portion 804 and a sealing member loading portion 802, and the third clamping portion includes a second clamping jaw 8031 ​​and a second driving assembly 8032.

Figure 5 The Z direction is shown in the figure) and the second type of sensor is clamped and placed.

[0075] For example, the first blanking box 6021 is provided with a locking portion (not shown) to prevent personnel from mixing the second type of sensors with the first type of sensors. Thus, by placing the second type of sensors that do not meet the performance testing requirements in the first blanking box 6021, the second type of sensors can be stored separately from the first type of sensors, reducing the risk of the second type of sensors being transferred.

[0076] In some possible implementations, continue to refer to Figure 6 Combined with Figure 1 The second unloading unit 62 further includes a sixth driving part 621 and a seventh driving part 622 , the first clamping part includes a first clamping jaw 3011 and a third driving assembly 612 , and the second unloading box 6022 includes a third unloading box 6023 and a fourth unloading box 6024 .

When the sensor 1 is a fourth type of sensor, the seventh driving portion 622 is configured to drive the second conveying portion 601 to transport the sensor 1 from a position near the third unloading box 6023 to an end of the second unloading unit 62 near the fourth unloading box 6024 along the first direction. The third driving assembly 612 of the second conveying portion 601 is configured to drive the first clamping jaw 3011 to move up and down along the third direction, and to grip and place the fourth type of sensor, so as to accommodate the fourth type of sensor in the fourth unloading box 6024.

[0079] Thus, the fourth type of sensors that do not meet the verification and testing requirements can be accommodated in the fourth blanking box 6024, and the third type of sensors that meet the performance testing and verification testing requirements can be accommodated in the third blanking box 6023, so that the fourth type of sensors and the third type of sensors can be stored separately, which is convenient for the subsequent reuse of the fourth type of sensors and the packaging and packaging of the third type of sensors, and can effectively improve work efficiency.
