Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

Fig. 1 is a perspective view of a performance detection device 10 that can detect the presence or absence of a seal ring according to this embodiment. Fig. 2 is a side view of the performance testing device 10 of this embodiment, which can detect the presence or absence of a seal ring. Fig. 3 is a rear view of the performance detection device 10 of the present embodiment, which can detect the presence or absence of a seal ring.

As shown in fig. 1, the performance detecting device 10 capable of detecting the presence or absence of a seal ring includes a performance detecting baffle 15 having an L-shaped cross section. The performance detection barrier 15 of the present embodiment is provided at the back with a shaft clamp 11 for fixing a detection object 20 (the detection object of the present embodiment is an ABS wheel speed sensor). The seal ring in the ABS wheel speed sensor 20 is mounted on the injection head, and therefore a through hole 16 through which a head 21 of the test object 20 passes is correspondingly provided in the performance testing barrier 15. In the case of fixing the ABS wheel speed sensor 20 with the shaft clamp 11, the head portion 21 of the ABS wheel speed sensor 20, to which the seal ring should be mounted, passes through the through hole 16, and protrudes to the front of the performance detection barrier 15.

The optical fiber sensor 12 is disposed above the through hole 16 of the performance detection baffle 15, so that when the ABS wheel speed sensor 20 is fixed to the performance detection baffle 15, the probe of the optical fiber sensor 12 faces the position of the head 21 of the ABS wheel speed sensor 20 where the seal ring is mounted. The optical fiber sensor is a sensor for converting the state of an object to be measured into a measurable optical signal, wherein the state of the object to be measured comprises light intensity, wavelength, frequency, phase and the like.

The optical fiber sensor 12 is connected to an optical fiber amplifier 13 for amplifying an optical signal. The top of the performance detection baffle 15 is provided with a support frame 14, the optical fiber amplifier 13 is provided with a sliding groove matched with the support frame 14, and the optical fiber amplifier 13 is supported above the performance detection baffle 15 by embedding the support frame 14 into the sliding groove of the optical fiber amplifier 13. The optical fiber amplifier 13 is connected to a controller 30 (not shown), and transmits the optical signal amplified by the optical fiber amplifier 13 to the controller 30.

The controller 30 determines whether or not a seal ring is present as a detection target, and controls the performance detection device 10 capable of detecting the presence or absence of a seal ring based on the determination result. The sealing ring is generally made of an elastic material such as rubber, and the reflective property of the sealing ring is different from that of other materials such as metal and plastic. Therefore, in the present embodiment, the controller 30 determines the presence or absence of the seal ring based on the amount of light reflected at the seal ring attachment position to be detected.

Specifically, the probe of the optical fiber sensor 12 is disposed at a position facing the seal ring-mounted head 21 of the ABS wheel speed sensor 20, receives a signal indicating the light intensity (reflected light amount) of the head 21, and then transmits the signal to the optical fiber amplifier 13. The optical fiber amplifier 13 amplifies the signal received from the optical fiber sensor 12 and sends it to the controller 30. The controller 30 is preset with a range of light intensity (light reflection amount) of the material of which the seal ring is made.

The controller 30 compares the received signal with a predetermined range, and if the signal is within the predetermined light intensity range, the controller 30 determines that a seal ring is present and controls the performance detection device 10 to perform performance detection. If the signal is not within the predetermined light intensity range, the controller 30 determines that the seal ring is not present and controls the performance detection device 10 not to perform the performance detection. The controller 30 may further include a traffic light, and when it is determined that the seal ring is not present, the controller 30 may turn on the traffic light to indicate to the operator that the seal ring is not present. In addition, the controller 30 may also alarm in other ways, such as sounding an alarm.

In the present embodiment, the detection object is fixed by the shaft clamp, but the present invention is not limited thereto, and the detection object may be fixed by other means and methods.

In the present embodiment, the ABS wheel speed sensor is used as a detection target, and the seal ring is provided at the head portion thereof, and therefore, a detection member for detecting the presence or absence of the seal ring is provided at a position facing the head portion.

Although the present invention has been described with reference to specific embodiments, it will be appreciated by those skilled in the art that the scope of the invention is not limited to the specific combination of features described above, but also covers other embodiments that can be formed by any combination of the above features or their equivalents without departing from the inventive concept. For example, the above features and (but not limited to) technical features having similar functions disclosed in the present invention are mutually replaced to form the technical solution.
