[0024] Specific work process: After an artificial worker or a robot places the combination switch 100 into the first combination switch carrier 411, the external wiring harness assembly is inserted into the wiring harness interface of the combination switch 100, and the calibration device is started. The first camera assembly 412 takes the first photo to detect whether there is a clock spring fixing buckle and a wiring harness. If so, the next operation is carried out, including initial angle calibration and initial gear calibration. If not, an alarm is given. After taking out the wiring harness and the buckle, the second photo is taken. If no buckle and wiring harness are detected, rotation test and centering test are carried out, including 0-position test and angle test. If there is a wiring harness or a buckle, an alarm is given. The rotation test drives the second rotating shaft 4132 and the rotating block 4133 to rotate through the first motor 4131. The rotation of the rotating block 4133 drives the clock spring in the combination switch 100. To test whether there is jamming of the clock spring within a larger angle range and whether the product angle detection at each typical angle is accurate, after the test is completed, the buckle is put in and the third photo is taken. If there is a buckle but no wiring harness, the photo is qualified. After passing the qualification, the combination switch 100 is taken out. If there is no buckle or there is a wiring harness, an alarm is given. After being calibrated and detected as qualified on the calibration machine table 41, the combination switch 100 is sent to the second combination switch carrier 4211 of the indexing plate 421 by the transfer robot 43. The indexing plate 421 rotates, and the second combination switch carrier 4211 passes through the supply test station, the backlight test station in turn. The backlight of the combination switch 100 is detected by the second camera assembly in the backlight test station. The shift lever handle test station 424 is used to test the gear shift function detection of the shift lever handle and the function detection of the P gear button. The first test station 425 of the steering handle is used to test the function detection of the upper and lower three-gear steering light levers of the steering handle and the pressing of the front washer two-gear button. The second test station 426 of the steering handle is used to test the function detection of the wiper knob on the steering handle and the forward and backward拨动 test of the rear wiper washer paddle on the steering handle. The third test station 427 of the steering handle is used to test the function detection of the front and rear four-gear levers of the steering handle, that is, the steering and lane change function test. After the detection is completed, it is unloaded through the loading and unloading station 422. The qualified combination switch 100 is placed on the qualified product discharge channel 51, and the unqualified combination switch 100 is placed on the unqualified product discharge channel 5251 for unloading. The calibration and automated test of the integrated combination switch 100 can stably and reliably meet the test requirements of such products; on the second test station 426 of the steering handle, there is also a clamping member 4263 and a thirty-fifth driving member 4264 for driving the clamping member 4263 to perform telescopic movement. The clamping member 4263 clamps or releases the steering handle under the action of the thirty-fifth driving member 4264, and can position the steering handle when the second jaw 4262 drives the knob on the steering handle to rotate, preventing it from being displaced due to influence and affecting the test of the knob.

[0025] Specific process of calibration and detection of the clock spring of the combination switch: I. 0-position angle calibration: After the first camera takes a qualified first photo of the product, the testing equipment sends an angle sensor function learning message command through the CAN bus to perform function learning on the clock spring angle sensor and complete the initial 0-position angle calibration of the clock spring.

[0026] II. Centering Test: The clock spring of the synchronous rotation combination switch rotates clockwise at a speed of 180° / s to the target angle of 1260°. Due to the inherent characteristics of the clock spring, a normally unhindered clock spring will reach its rotation limit between 900° and 1044°, at which point it will be unable to continue rotating. Subsequently, the rotational torque will suddenly increase. By setting an overload protection torque value, once the torque exceeds the specified value, the rotation stops and the current rotation angle is read. This angle is then compared with the set upper and lower limits of the clock spring alignment test. If the angle is within the range, the alignment test is successful; if it is outside the range, the alignment test is unsuccessful, the device returns to the 0 position, and an alarm sounds while waiting for unlocking. The stopping torque for this alignment test should be less than the maximum torque that can be received during the entire rotation test to avoid damage to the clock spring caused by the alignment test.

[0027] III. 0-bit test: After the centering test is completed normally, the equipment performs a zero-position test. The rotating shaft of the equipment synchronously rotates the clock spring of the combination switch to the calibrated zero position. The equipment then reads and judges whether the angle returned by the product angle sensor is within the qualified angle range of the zero position via the CAN bus.

[0028] IV. Angle Test: After the 0-position test, a series of rotation angle tests are conducted, including clockwise rotation, counterclockwise rotation, and tests of various typical angles. The main purpose is to test whether the clock spring has any jamming phenomenon in a larger angle range, and whether the product angle detection is accurate under various typical angles. The rotation speed is 180° / S. The specific angle test items are as follows: (1) 90° counterclockwise test; (2) 700° counterclockwise test; (3) 700° clockwise test; (4) 180° clockwise test; (5) 360° clockwise test; (6) 700° clockwise test; (7) 700° counterclockwise test.

[0029] After the rotation test is completed, the equipment drives the product back to 0, the employee inserts the buckle, and ensures that there are no wires on the clock spring before taking a third photo.

[0030] After calibration and testing on the calibration machine, the combination switch on the first carrier is transferred to the second carrier on the indexing plate by a transfer robot. The indexing plate rotates, and the second carrier passes through the test stations in sequence. The backlight test station tests the backlight detection of the combination switch through the second camera component. The column shifter test station is used to test the shifting function of the column shifter and the function of the P gear button. The first test station of the steering handle is used to test the function of the three-position lever of the steering handle and the pressing test of the two-position button of the front washer. The second test station of the steering handle is used to test the function of the wiper knob on the steering handle and the forward and backward movement test of the rear wiper washer paddle on the steering handle. The third test station of the steering handle is used to test the function of the four-position lever of the steering handle, that is, the steering and lane change function test. After the test is completed, the combination switch is unloaded through the loading and unloading station. The transfer robot places the tested combination switch on the qualified or unqualified conveyor belt for discharge.
