Description

The present invention relates to a vehicle inspection line test system.

[Conventional technology]

In a vehicle inspection line at an automobile factory, roughly, conventionally, for example, in a plan view in FIG. 6, a completed vehicle carried out in an arrow direction from the assembly run-in 01 is first subjected to a brake test in a brake tester 03 in a manner described later.
Next, after the speedometer test was performed in the speedometer tester 04, the axis side slip tester
After going to 05, the side slip test of the axis is performed here, the steering angle test of the wheel is performed by the turning radius tester 07, and the optical axis aiming test is performed by the headlight tester 09. 010 and the weighing scale tester 011 are carried out.

Here, the brake test and the speedometer test will be outlined. First, in the brake tester 03, as shown in the side view of FIG. 7, the wheel 020 is mounted on a pair of front and rear parallel friction rollers, and Is driven by a motor to rotate the mounted wheel 020 at a set speed.

Now, when the brake pedal of the test vehicle is depressed, the upper wheels are braked, and the friction roller pair 4-2 slightly tilts around its horizontal neutral axis N as indicated by an arrow, so that its rotation angle is increased. Thus, the braking torque of the wheels can be obtained.

In the speedometer tester 04, the eighth
As shown in the side view of FIG.
The test is performed by rotating the driving wheel 021 on the pair of running rollers 5-2 and comparing the speedometer reading of the test vehicle with the speed obtained from the rotation speed of the running rollers 5-2.

[Problems to be solved by the invention]

In such a conventional vehicle inspection line, when performing various checks and tests, the inspector has a checklist, checks checkpoints one by one, and fills out using a writing instrument, so it takes a little time for work, In addition, there are problems such as misreading, misunderstanding, erroneous entry, etc., and this problem is particularly serious when a vehicle type is mixedly mounted on an assembly line.

In recent years, automobiles having an auto-cruise function and an anti-sted function have been considerably produced. Since performance tests of such devices are performed electrically, the conventional handwriting based on the five senses of an inspector is used. There is a demand for the development of an automated test system that saves labor and manpower by automatically performing the progress and management of all tests and creating a grade sheet, instead of creating a checklist by filling in. .

The present invention has been proposed in view of such circumstances,
It can also be applied to mixed assembly lines of various vehicles such as vehicles equipped with auto cruise, inch skid function, etc.
It is an object of the present invention to provide a labor-saving, labor-saving, and economical vehicle inspection line test system that performs various tests safely, quickly, and reliably.

[Means for solving the problem]

Therefore, the present invention, in a vehicle inspection line test system that is provided on a mixed loading assembly line where a plurality of types of vehicles are assembled and inspects a completed vehicle with predetermined inspection items, has order information of vehicles produced on the mixed loading assembly line, A host computer that outputs the model information of the vehicle to be inspected from the same rank information, and the model that incorporates the model information, inspection items and inspection standards for each model produced by the mixed assembly line, and receives from the host computer A small computer that outputs the inspection item of the model in response to the information, and records and displays the determination result of the inspection result based on the inspection standard when the inspection result for the inspection item is input; Receives the above inspection items of the vehicle to be inspected output from the small computer and sounds them via the headphone With important more inspector, characterized in that the same test result received through the microphone by the sound of the inspectors test results of the test item equipped with a voice instruction response unit output to the small computer.

(Operation)

With such a configuration, the computer operates in conjunction with the order of the types of vehicles traveling on the assembly line, and when the order signal of the vehicle to be inspected enters the host computer, the small computer gives a voice instruction of the inspection item in conjunction with the signal. Inform the inspector's head horn via the response device. The inspector performs the test according to the instructions, and responds the test results to the small computer via the microphone and the voice instruction response device. The test results are processed by the computer, and the test results and the judgment results are printed.

〔Example〕

Referring to the drawings, one embodiment of the present invention will be described. FIG. 1 is an explanatory view of the operation, FIGS. 2 and 3 are partial plan views, partial side views, and FIG. FIG. 5 is a side view showing the speedometer tester of FIG.
The figure is a rear view showing a speedometer tester having a structure different from that of FIG.

First, in FIG. 1, the same reference numerals as those in FIG. 6 denote the same members as those in FIG. 6, and 1 denotes a host computer, 2 denotes a small computer, and 3 denotes an inspector by the action of the host computer 1 and the small computer 2. A voice response inspection device that gives instructions and responses to the inspector by voice through a headphone and a microphone, 4 is a brake tester that can perform not only a conventional brake test but also an anti-skid performance test, and 5 is a conventional speedometer test In addition to this, it is a speedometer tester that can also perform abnormal vibration detection and auto cruise performance test during the above test, and these are shaft side slip testers including those for inspection and correction confirmation shown in FIG. , Headlight tester including optical axis aiming
The inspection device 6 is formed together with 09.

In such a vehicle inspection line system, when the sequence signal a of the vehicle to be inspected enters the host computer 1 from the mixed assembly line, the corresponding model information b enters the small computer 2 from the host computer 1 and the small computer 2 receives the model data and the inspection. Items and inspection standards are built in,
The inspection item c is transmitted to the head horn of the inspector via the voice instruction response device 3.

Then, when the inspector responds to the test result d via the microphone, the response enters the small computer 2 via the voice instruction response device 3, and when the response is recorded,
The judgment result e is printed.

In this manner, the inspector operates in accordance with the instruction from the voice instruction response device, so that the various tests proceed smoothly as prescribed in the hierarchical order.

Here, the brake test and the speedometer test will be described. First, the brake tester 4 drives a pair of left and right friction rollers 4-2 as shown in the plan view of FIG. 2 and the side view of FIG. In order to do so, the variable-speed DC motors 4-1 and 4-1 are attached,
After both DC motors are driven at the same speed, the brake test can be performed in the same manner as before by depressing the brake of the test vehicle. Here, 4-5 is a center gear, 4-6 is a gear, 4-7 is a roller unit, 4
-8 is a bearing.

Now, in order to perform the anti-skid performance test, the rotational speeds of both the DC motors 4-1 and 4-1 are set to different rotational speeds as instructed by the voice instruction response device 3, and a brake test is performed.

In other words, one of the left and right wheels has a high rotation speed, the other has a low rotation speed, and the wheels having a high rotation speed are on the slippery road surface, and the wheels having a low rotation speed are on the same road surface condition as on the slippery road surface. Then, a brake test is performed.

Here, if the action of the anti-skid is good, the neutral axis NN of the pair of left and right roller units 4-7 and 4-7 is used.
The difference between the surrounding rotation angles is less than the allowable angle, but if the action of the anti-skid is poor, the difference between the rotation angles will exceed the allowable angle, and the data at that time will be smaller due to the response of the inspector. The result is sent to a computer, from which the judgment result is printed together with the inspection result.

Next, in the speedometer test, as shown in FIG.
-2 is provided with a brake 5-1. At the same time, a sensor 5-3 for detecting abnormal vibration and a vibrometer 5-4 are provided.
Is attached.

Therefore, the running roller 5-2 is connected to the brake 5-1.
As before, it can be used for speedometer tests without using a car, but by applying a slight brake, the same load conditions as those when climbing up and downhill are given to the wheels, and A performance test can also be performed, and since vibration of the axle or running roller can be detected during the test, if this exceeds a normal vibration level, the occurrence of abnormal vibration can be detected.

Note that the wheel vibration detecting means in FIG.
As shown in the figure, vibrations near the left and right ends of the axle 5-6 are detected by sensors 5-3 and 5-3 protruding from the air cylinders 5-7 and 5-7, respectively, and the vibrations are detected by the vibrometer 5 respectively. -4, 5-4 can also be displayed.

Regardless of which means, when abnormal vibration is detected, the cause is determined by a precision test, and the cause is, for example, a bolt clogged between double tires,
It turns out that the pebbles are stuck in the grooves of the tire tread,
By removing this, it is possible to prevent the occurrence of an accident during traveling.

〔The invention's effect〕

 According to such a device, the following effects can be obtained.

(1) The small computer outputs the inspection items of the vehicle type / model of the vehicle to be inspected in accordance with the vehicle hierarchy information output from the host computer having the vehicle type / model information of a plurality of types of vehicles flowing through the assembly line, and outputs this. The received voice instruction response device gives an instruction to the inspector by voice through the headphone to the inspector, and the inspector follows the instruction, conducts the inspection of the specified inspection item, and reports the result to the microphone. Inspections are conducted according to the inspection items instructed by voice through the headphone, even if there are multiple types and models of vehicles flowing through the line, and as a result Only the task of responding to the voice instruction responding device by voice through the microphone can reduce the burden on the inspector and ensure that the inspection is performed efficiently.

(2) Even if the assembly line is a mixed line, the inspection line can perform a test corresponding to this.

(3) The tester does not need to hand-write the data on the checklist, so that the response is quick and reliable.

(4) Since the tester only has to respond by voice to the voice command transmitted via the headphone, the command and response are promptly and reliably performed, and errors are reduced.

(5) The fatigue of the inspector is reduced.
