At present, some technical solutions for sensor testing have also appeared, for example, a touch sensor sensitivity testing device recorded in publication number CN220270494U. The utility model provides a touch sensor sensitivity testing device that can conveniently test the touch area and touch frequency sensitivity of a touch sensor. A touch sensor sensitivity testing device includes a test bench, an operation panel and a conversion mechanism. The left side of the test bench is connected to the operation panel, and the operation panel can be electrically connected to the touch sensor. The right side of the test bench is provided with a conversion mechanism for switching the touch area and touch position;

[0003] Although the above device can adjust the contact area and frequency, it can only detect one sensor at a time, resulting in high cost and single functionality of the device, making it inconvenient to detect multiple sensors, resulting in reduced detection efficiency of the device.

[0023] Specifically, when in use, the controller and the collector are placed on the upper surface of the test bench 1, the touch sensor is installed on the mounting plate 402, the positions of the multiple inner rods 603 are manually adjusted, the rotating disk 6 starts to rotate, and the multiple distance sensors 202 measure the distance between the two. During rotation, the contact piece 7 contacts the touch sensor, and multiple groups of data generated during rotation are collected by an external controller and collector, and data related to sensor sensitivity are obtained by comparing the subsequent data.

[0024] Embodiment 1

[0025] like Figure 1 and 2 As shown, in this embodiment, a protective cover 101 is fixedly connected to the upper surface of the test bench 1 , and supporting legs 102 are fixedly connected to the lower surface of the test bench 1 near the four corners.

[0026] In this embodiment, the protective cover 101 is used to isolate the mist generated by the sprayer 301 and protect the controller and data acquisition device between the protective cover 101 and the test bench 1. The connection between the controller, the data acquisition device and the sensor belongs to the prior art and will not be elaborated in this article.

[0027] like Figure 3 As shown, the upper surface of the sliding plate 203 is detachably connected to the guide seat 204 near the edge positions on both sides, the inner surface of the power box 5 is provided with a slide groove 506, the sliding plate 203 and the slide groove 506 are slidably connected, the guide seat 204 is in contact with the inner surface of the power box 5, and the upper surface of the limit frame 4 is fixedly connected with the No. 2 self-locking electric push rod 401, the output end of the No. 2 self-locking electric push rod 401 is fixedly connected to the mounting plate 402, and the upper surface of the mounting plate 402 is provided with a mounting hole.

[0028] In this embodiment, since the mounting frame 2 and the test bench 1 are fixedly connected, after starting the No. 1 self-locking electric push rod 201, the output end of the No. 1 self-locking electric push rod 201 pushes the sliding plate 203 to cooperate with the guide seat 204 to slide along the slide groove 506, thereby changing the position of the limit frame 4 and further changing the position of the touch sensor.

When the No. 2 self-locking electric push rod 401 is started, the output end of the No. 2 self-locking electric push rod 401 drives the mounting plate 402 to move upward or downward, thereby facilitating the contact between touch sensors of different specifications and the contact piece 7, thereby improving the applicability of the device.

[0029] like Figure 2 As shown, the upper surface of the sliding plate 203 is fixedly connected with a sprayer 301 .

[0030] In this embodiment, the roasting lamp 3 increases the temperature around the sensor, and the sprayer 301 can perform a spraying operation, and then record the data before the operation, and record the data after starting the roasting lamp 3 and the sprayer 301. By comparing the two sets of data, the influence of fog and temperature on the sensitivity of the sensor can be known.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, in order to make up for the problem that it is inconvenient to adjust the distance between the distance sensor 202 and the measuring disk 606 in the first embodiment, resulting in the acquired data being relatively single.

[0034] In this embodiment, the stepper motor 502 is started, and the output end of the stepper motor 502 drives the worm 503 to rotate, and the worm 503 drives the worm wheel 505 to rotate, so that the rotating shaft 504 fixedly connected to the worm wheel 505 can rotate, and the rotating disk 6 can be driven to rotate through the rotating shaft 504, so that the contact piece 7 slides on the touch sensor.

[0035] like Figure 4 As shown, a through groove 602 is provided on the outer surface of the mounting tube 601, a scale is provided on the outer surface of the inner rod 603, a limit strip 604 is fixedly connected to the outer surface of the inner rod 603, a locking knob 605 is threadedly connected to the outer surface of the mounting tube 601, and a measuring disk 606 is fixedly connected to the front end of the inner rod 603.

[0036] In this embodiment, the scale can be observed through the through slot 602, so as to record the length of the inner rod 603 extending out of the mounting tube 601. By rotating the locking knob 605, one end of the locking knob 605 can be brought into contact with or separated from the inner rod 603 under the push of the thread, thereby achieving the fixation of the adjusted inner rod 603, and further changing the distance between the multiple measuring disks 606 and the distance sensor 202. Multiple groups of data can be measured in one rotation, thereby improving the efficiency of the sensor sensitivity test.

Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
