Description

Technical Field

[0001] This utility model relates to the field of sensor detection technology, and more specifically, to a quality inspection device for the production of seat sensors. Background Technology

[0002] Car seats are an important component of a car's interior, directly affecting the comfort, safety, and health of the driver and passengers. Seats not only need to meet comfort requirements but also comply with safety standards and offer versatility. Car seats are equipped with pressure sensors to detect the presence of passengers or the driver, reminding them to fasten their seatbelts and determining whether to activate the airbag system based on the presence of passengers.

[0003] Cars often experience bumps and vibrations while driving, which causes pressure sensors to vibrate during use. Therefore, it is necessary to perform quality testing on pressure sensors in such a turbulent environment. However, general pressure sensor testing equipment can only perform pressure testing on pressure sensors. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 6 As shown, this utility model provides a quality inspection device for the production of seat sensors, including an inspection table 1. A support plate 101 is fixedly connected to the top of the inspection table 1. A drive assembly 2 is installed at the bottom of the front of the support plate 101. A transmission assembly 3 is installed in the middle of the front of the support plate 101. A top plate 4 is fixedly connected to the top of the support plate 101. A shaking assembly 5 is installed on the front of the top plate 4. An installation assembly 6 is installed on the top of the shaking assembly 5. The transmission assembly 3 includes a rotating rod 301 movably installed on the front of the support plate 101. The front of the rotating rod 301 is fixedly connected to... A fixed plate 302 is provided. A first cylindrical block 303 is fixedly connected to the surface of the fixed plate 302 away from the rotating rod 301. A connecting plate 304 is movably sleeved on the outer side of the first cylindrical block 303. The shaking assembly 5 includes a positioning frame 501. A lifting plate 502 is movably sleeved on the inner side of the positioning frame 501. A bottom plate 503 is fixedly connected to the bottom of the lifting plate 502. A fixed block 504 is fixedly connected to the bottom of the bottom plate 503. A second cylindrical block 505 is fixedly connected to the inner side of the fixed block 504. The second cylindrical block 505 is movably sleeved on the top of the connecting plate 304.

[0024] The counting device 405 is a common prior art, and will not be described in detail in this application.

[0025] In this embodiment, the sensor is fixed inside the mounting frame 601. The starter motor 201 drives the drive gear 202 to rotate, which in turn drives the rotating rod 301 to rotate through meshing with the driven gear 305. The rotating rod 301 then drives the fixing plate 302 to rotate. During the rotation of the fixing plate 302, the connecting plate 304 drives the lifting plate 502 to move vertically up and down reciprocally inside the positioning frame 501, which in turn drives the mounting assembly 6 to move vertically reciprocally, thus realizing the shaking of the sensor. After the shaking detection is completed, the sensor is tested to see if it can work normally, and the quality of the sensor is judged based on the detection results.

[0026] Among them, rollers 511 are movably sleeved around the inner wall of the positioning frame 501, and the rollers 511 are in contact with the surface of the lifting plate 502.

[0027] When the lifting plate 502 moves along the inner side of the positioning frame 501, the roller 511 rolls against the surface of the lifting plate 502 to prevent the lifting plate 502 from getting stuck during movement and to reduce friction.

[0028] The drive assembly 2 includes a motor 201 fixedly connected to the back of the support plate 101. The output shaft of the motor 201 is fixedly connected to a drive gear 202. A driven gear 305 is fixedly sleeved in the middle of the outer side of the rotating rod 301. The driven gear 305 meshes with the drive gear 202.

[0029] The start, stop and speed of the motor 201 can be controlled via the control panel 102, thereby adjusting the speed of sensor oscillation during the detection process.

[0030] The top plate 4 has a fixing groove 401 on its front side. The positioning frame 501 is fixedly connected to the inner side of the fixing groove 401. A cylindrical tube 402 is fixedly sleeved on the top of the top plate 4. A buffer spring 403 is fixedly connected to the bottom of the inner side of the cylindrical tube 402. A telescopic rod 404 is fixedly connected to the top of the buffer spring 403. The telescopic rod 404 is movably sleeved with the cylindrical tube 402. A counting device 405 is installed on the top of the telescopic rod 404. A control panel 102 is installed on the top of the detection table 1. The control panel 102, the motor 201, and the counting device 405 are all electrically connected through wires.

[0031] When the mounting component 6 moves down to its lowest position, the bottom of the mounting frame 601 contacts the counting device 405. Each time it contacts the device, the counting device 405 counts once and transmits the result to the control panel 102.

[0032] The installation component 6 includes an installation frame 601 fixedly connected to the top of the lifting plate 502. A support plate 602 is fixedly connected to the top of the installation frame 601. A cylindrical rod 603 is movably sleeved on the top of the support plate 602. A pressing plate 604 is movably connected to the bottom of the cylindrical rod 603. A pressure spring 605 is provided on the outside of the cylindrical rod 603. The pressure spring 605 is located between the pressing plate 604 and the support plate 602.

[0033] The pressure spring 605 exerts a downward thrust on the pressing plate 604, thereby pressing and fixing the sensor to the inside of the mounting frame 601.

[0034] The top of the central cylindrical rod 603 is fixedly connected to a fixing ring 606, and both sides of the central cylindrical rod 603 are fixedly connected to movable limiting blocks 607. The middle of the top of the support plate 602 is fixedly connected to a fixing limiting plate 608.

[0035] When the sensor needs to be removed or placed, the central cylindrical rod 603 is pulled vertically upward by the fixing ring 606, and then the fixing ring 606 is rotated 90 degrees so that the movable limiting block 607 and the fixed limiting plate 608 are in the same vertical direction. Thus, the fixed limiting plate 608 can support the movable limiting block 607, keeping the pressing plate 604 away from the bottom of the inner wall of the mounting frame 601, which makes it easier to remove or place the sensor.

[0036] Working principle and usage process of this utility model:

[0037] The sensor is fixed inside the mounting frame 601. The starting motor 201 drives the drive gear 202 to rotate, which in turn drives the rotating rod 301 to rotate through meshing with the driven gear 305. The rotating rod 301 then drives the fixing plate 302 to rotate. During the rotation of the fixing plate 302, the connecting plate 304 drives the lifting plate 502 to move vertically up and down and back and forth inside the positioning frame 501. This, in turn, drives the mounting assembly 6 to move vertically back and forth, thus realizing the shaking of the sensor. After the shaking detection is completed, the sensor is tested to see if it can work normally, and the quality of the sensor is judged based on the test results.

[0038] When the mounting component 6 moves down to its lowest position, the bottom of the mounting frame 601 contacts the counting device 405. Each time it contacts the device, the counting device 405 counts once and transmits the result to the control panel 102.
