In order to achieve the above object, the inspection device of the present invention is a motor drive unit for driving a motor to operate an automatic switchgear, a measurement unit for measuring a motor load, and a motor load A storage unit that stores discrimination reference data,
The judgment unit that judges the quality of the automatic switchgear by comparing the measured data of the motor load with the judgment reference data, and the judgment timing for comparing the measured data in the judgment unit with the judgment reference data is the operation amount of the automatic switchgear. And a program setting unit for dividing and setting the parameter indicating the parameter at predetermined unit intervals.

[0006]

Operation: The measured data of the motor load and the discrimination reference data are compared for each discrimination timing set based on the parameter indicating the operation amount of the automatic switchgear to clarify the presence or absence of abnormality at each discrimination timing. The quality of is judged.

In this case, the parameter may be set as the operating time of the automatic switchgear, and the quality of the automatic switchgear may be determined by comparing the motor load with the determination reference data at predetermined time intervals. The operation stroke of the automatic opening / closing device may be compared with the motor load at a predetermined stroke interval and the determination reference data to determine the quality of the automatic opening / closing device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes an automatic opening / closing device for a vehicle such as a sunroof or a power window which is opened / closed by a motor 1a, and is a bar recording basic data such as a model of the opening / closing device 1. Data storage means 1b including a code and the like
Is attached.

Reference numeral 2 is an inspection device for judging the quality of the automatic opening / closing device 1. The inspection device 2 includes a reading unit 3 that reads basic data from the data recording unit 1b of the automatic opening / closing device 1 by the sensor 3a, and a motor driving unit 4 that drives the motor 1a of the automatic opening / closing device 1 to operate the automatic opening / closing device 1. , A measuring unit 5 for measuring the load current of the motor 1a, and the motor 1a
Storage unit 6 that stores the determination reference data of the load current, and a determination unit 7 that determines the quality of the automatic switchgear 1 by comparing the measurement data of the load current of the motor 1a and the determination reference data.
The automatic switching device 1 includes a program setting part 8 for dividing and setting the determination timing for comparing the measured data in the determination part 7 with the determination reference data at predetermined unit intervals of the parameter indicating the operation amount of the automatic switching device 1. A recording unit 9 for recording, displaying, and outputting the measurement data and the judgment result of
The display unit 10 and the output unit 11 are provided.

Next, the inspection process by the inspection device 2 will be described by taking a sunroof for a vehicle as an example of the automatic opening / closing device 1.
As shown in FIG. 2, the inspection of the sunroof is performed in the order of the inspection device connecting step S1, the basic data reading step S2, the measurement program setting step S3, the motor load measuring step S4, the data comparing step S5, and the data processing step S6. Be done. First, in the connecting step S1 of the inspection device, the motor drive unit 4 of the inspection device 2 is connected to the motor 1a of the automatic opening / closing device 1. In the next basic data reading step S2, the basic data of the automatic switchgear 1 is read from the data storage means 1b by the sensor 3a of the reading unit 3. In the next measurement program setting step S3, the program setting unit 8 divides and sets the determination timing at which the measurement data and the determination reference data are compared based on the basic data according to the parameter indicating the operation amount of the automatic switchgear. Further, based on the basic data of the automatic opening / closing device 1, the discrimination reference data corresponding to the model to be inspected is selected from the discrimination reference data stored in the storage unit 6.

In this embodiment, the parameter indicating the operation amount of the automatic opening / closing device 1 is the operating time of the automatic opening / closing device 1, and the time required for the opening operation of the automatic opening / closing device 1 is I1 to I10.
Further, the determination timing was set by dividing the time required for the closing operation from I11 to I20 at intervals of 0.4 seconds, and the measurement program was set to detect the maximum current value at each determination timing. Then, in the measurement step S4, a drive command is given to the motor drive unit 4, and the motor 1
a is driven to open / close the automatic opening / closing device 1 and the current value of the motor 1a at that time is measured by the measuring unit 5, and the above-mentioned I
The maximum current value for each determination timing from 1 to I20 is detected. Then, in the next data comparison step S5, the determination unit 7 compares the maximum current value at each determination timing with the determination reference data to determine the quality of the sunroof. The discrimination reference data indicates the upper limit value of the load current of the motor 1a at the discrimination timing, and an abnormality has occurred where the detected maximum current value is higher than the discrimination reference data. Tables 1 and 2 below show an example of the measurement results during the opening and closing operations of the automatic switchgear 1.

[0012]

[Table 1]

[0013]

[Table 2]

According to the measurement result, the maximum current value at the determination timing I6 of the opening operation of the automatic switchgear 1 is 10.6 A.
That is, it is higher than the discrimination reference data value of 6.0 A, indicating that there is an abnormality at the discrimination timing I6. At other determination timings, the maximum current value is lower than the determination reference data value, indicating that there is no abnormality. When these measurement data are graphed as shown in FIGS. 3 (a) and 3 (b), when the sunroof is closed, the graph a showing the measurement data follows the graph b showing the discrimination reference data and is normal. It indicates that there is. Further, during the opening operation of the automatic opening / closing device 1, the graph a showing the measurement data exceeds the graph b showing the judgment reference data at the judgment timing I6, and the graph a showing the measurement data shows the judgment reference data at the judgment timings I7 to I9. The graph a showing the measurement data does not exceed the graph b showing the above, but the graph a showing the measurement data follows the graph b showing the judgment reference data as in the case where the operating state is normal by the small movement of the graph a showing the measurement data. It means that there is something wrong with the operating state. In the next data processing step S6, the measurement result and the comparison result are displayed on the display unit 10.
As a result, it becomes possible to easily and surely determine the quality of the automatic switchgear 1, and it is possible to specify the location where the abnormality has occurred.

In the case of this embodiment, the parameter indicating the operation amount of the automatic opening / closing device 1 is the opening / closing operation time of the automatic opening / closing device 1, but it may be the operation stroke of the automatic opening / closing device 1. In this case, the location where the abnormality has occurred can be specified by the operating distance of the automatic opening / closing device 1.

[0016]

As is apparent from the above description, according to the present invention, it is possible to easily and surely perform the work of judging the quality of the automatic switchgear and the location of the abnormality, and no skill is required for the judgment work. As soon as it becomes, the abnormality can be immediately adjusted.
