The locking or unlocking of the angle adjuster of such a structure is embodied by the meshing or disengaging of the teeth of the pinion plate and the lock tooth of the foregoing gear ring. However, due to the comprehensive factors such as error accumulation of the automatic production process chain and / or dynamic working condition interference, there inevitably exists an angle deviation of the lock tooth of the gear ring, which affects the probability of the meshing of the pinion plate. Moreover, the fluctuation of raw materials such as uneven thickness of the plate (existence of tolerance), material rebound difference, stamping forming process error, mold wear, positioning deviation (feeding and positioning error of the plate during stamping), inconsistent heat treatment deformation, part matching tolerance, assembly stress interference, environmental factors, etc., etc., may also cause the angle deviation of the lock tooth. Therefore, the detection and correction of the angle of the lock tooth of the gear ring of the tooth disc are of positive significance for the good meshing of a group of pinion plates and the lock tooth, at least including: ensuring the meshing accuracy, avoiding locking failure or abnormal sound during adjustment; suppressing the cumulative error of multiple teeth; avoiding the risk of locking failure, preventing the accidental backward tilting of the seat backrest during emergency braking of the vehicle, ensuring the safety of the passengers; eliminating abnormal sound and vibration; improving the operation comfort on the vehicle, etc. CONTENT OF THE UTILITY MODEL

[0032] Please refer to Figure 2 and in combination with Figure 1 , Figure 1 The automobile seat angle adjuster automation assembly line 100 in the form of a conveyor belt mentioned several times above is shown, and a carrier platform 7, which can also be referred to as an angle adjuster clamping platform, is also shown. After the current process is completed and the tooth disc 81 of the automobile seat angle adjuster 8 is covered on the tooth disc seat, the central position of the tooth disc 81 has an operation shaft hole 811, which is used for cooperation with an operation device, which can be manual or electric. The position corresponding to the operation shaft hole 811 is exactly the cam shaft hole of the cam block driving mechanism of the structural system of the automobile seat angle adjuster 8. Locking teeth are formed on the inner wall of the tooth disc 81 and around the circumferential direction of the inner wall. The driving mechanism with a cam block drives a set of tooth blocks (also referred to as "tooth plates" below) to move. The number of tooth blocks is usually four, but can also be three or even two C-shaped tooth blocks. The cam block corresponds to the central area of the opposite end of the set of tooth blocks and can simultaneously act on the set of tooth blocks. The set of tooth blocks has tooth block teeth at one end facing the locking teeth on the inner wall of the tooth disc 81. When the driving mechanism with a cam block moves in the clockwise direction and the set of tooth blocks moves in the direction of the locking teeth, the tooth block teeth engage with the locking teeth of the tooth disc 81, and vice versa. Since the automobile seat angle adjuster 8 of the present embodiment is mainly but not limited to the structure of CN205468633U (automobile seat angle adjuster) and CN205468634U (a kind of automobile seat angle adjuster) mentioned in the background art column above, the applicant will not repeat the specific structure of the automobile seat angle adjuster 8, because the skilled person in the art can fully understand it by reading the above-mentioned patent documents which are not limited to the examples.

[0033] The toothed plate driving member fitting head 443 extending below the toothed plate driving member rotating shaft 44 is actually equivalent to or simulates the components of the driving mechanism with the cam block in use. In the utility model, the angle through by the detection motor 41, that is, the angle through by the toothed plate driving member rotating shaft 44 is consistent with the preset angle of the rotary encoder 6. If it is not consistent, it indicates that the tooth block teeth of the aforementioned set of tooth blocks fail to mesh with the locking teeth of the tooth disc 81, so it is necessary to correct the tooth disc 81, make it rotate through an angle until the tooth block teeth mesh with the locking teeth, because only in the meshing state can the angle through by the detection motor 41 be consistent with the correct angle of the preset rotary encoder 6.

[0034] When the aforementioned carrier platform 7 is transported to the position of the testing station where the utility model is located, the carrier platform 7 is paused to move in order to be detected by the utility model device, and the specific process is as follows: the aforementioned mounting rack lifting drive cylinder 22 works, and the mounting rack lifting drive cylinder column 221 drives the lock tooth detection mechanism mounting rack 3 to descend, and the descending degree is that one left buffer air spring 36 and right buffer air spring 37 in the lower part of each of the pair of left buffer air springs 36 and right buffer air springs 37 descend to the limit (the specific stroke is controlled by an electrical controller). At this time, due to the descending of the aforementioned lock tooth detection mechanism mounting rack 3, the tooth plate driving part fitting head 443 at the lower part of the tooth plate driving part rotating shaft 44 extends into or is inserted into the operation shaft hole 811 of the tooth disc 81, and a group of tooth disc pressing rods 561 abut against the surface of the tooth disc 81 towards the upper part. Then the detection motor 41 works, drives the detection reduction box 42, drives the limiting boss clutch block 43 through the detection reduction box shaft 421, drives the limiting boss 45 to rotate through the clutch block pull spring connecting rod 431, the pull spring 46 and the limiting boss pull spring connecting piece 451, at this time, the limiting boss 45 drives the rotating shaft driving head 442 to make the tooth plate driving part rotating shaft 44 rotate, at the same time, the tooth plate driving part rotating shaft 44 drives the large transmission belt pulley 47, drives the small transmission belt pulley 49 through the transmission belt 48, since the small transmission belt pulley 49 is fixed on the rotating encoder shaft 61 of the rotary encoder 6, the rotating encoder shaft 61 is driven, and the rotary encoder 6 obtains the angle of rotation of the detection motor 41. At the same time, since the tooth plate driving part fitting head 443 is inserted into the aforementioned drive mechanism with cam block of the structural system of the automobile seat angle adjuster 8 (for details, please refer to the aforementioned CN205468633U and CN205468634U) through the operation shaft hole 811, the tooth plate driving part fitting head 443 drives the aforementioned one group of tooth blocks to displace through the rotation of the drive mechanism with cam block, so that the tooth block teeth are engaged with the lock teeth of the tooth disc 81. As mentioned above, if the angle of rotation of the detection motor 41 is consistent with the preset angle of rotation of the rotary encoder 6, that is, the same, it indicates that the installation position of the tooth disc 81 is correct, and the rotary encoder 6 feeds back the signal to the electrical controller, so that the mounting rack lifting drive cylinder 22 of the aforementioned lock tooth detection mechanism mounting rack lifting drive mechanism 2 works reversely relative to the aforementioned, until the tooth plate driving part fitting head 443 exits the operation shaft hole 811 of the tooth disc 81 upwards, and the carrier platform 7 moves away from the testing station where the utility model is located. The next carrier platform 7 carrying the automobile seat angle adjuster 8 to be detected enters the testing station.

[0035] During the above-mentioned testing process, if the rotating angle of the detection motor 41 is inconsistent with the preset angle of the rotary encoder 6, it indicates that the teeth of the tooth block and the locking teeth of the tooth disc 81 fail to engage, and thus the tooth disc 81 needs to be rectified, that is, the tooth disc 81 is slightly turned through an angle. Specifically, the rectification motor 51 is operated to drive the rectification reduction box 52, the rectification reduction box shaft 521 drives the rectification driving wheel 53, the rectification driving wheel 53 drives the rectification wheel 54, and a group of tooth disc pressure rods 561 (four in the embodiment) of the aforementioned pressure rod disc 56 fixed to the lower part of the rectification wheel 54 abut against the tooth disc 81 like fingers, so that the tooth disc 81 is forced to turn through a certain angle by the group of tooth disc pressure rods 561. The aforementioned locking tooth angle detection mechanism is repeatedly started, the tooth plate driving member rotating shaft 44 is rotated according to the process described by the applicant above, and the tooth plate driving member fitting head 443 acts on the driving mechanism with the cam block. The driving mechanism moves a group of tooth blocks to the direction of the locking teeth of the tooth disc 81 through the cam block. If the tooth block teeth of the tooth block engage with the locking teeth of the tooth disc, the rotating angle of the detection motor 41 will necessarily be consistent with the preset angle of the rotary encoder 6. If they are consistent, it indicates that the rectification work of the tooth disc 81 is completed, and the aforementioned tooth plate driving member rotating shaft 44 is raised under the reverse operation of the mounting frame lifting driving action cylinder 22. The carrier platform 7 leaves the detection station. It should be noted that if the rotating angle of the detection motor 41 is inconsistent with the preset angle of the rotary encoder 6, the mounting frame lifting driving action cylinder 22 will not be temporarily reversed, but will still press the group of tooth disc pressure rods 561 against the tooth disc 81 and rectify the tooth disc 81 by the locking tooth angle rectification mechanism 5 until the rotating angle of the detection motor 41 is consistent with the preset angle of the rotary encoder 6.

[0036] In summary, the technical scheme provided by the utility model makes up for the defects in the prior art, successfully completes the invention task, and truly realizes the technical effects described in the technical effect column above.
