Description

  The present invention relates to an inspection table on which an inspection object to be inspected visually is placed.

An example of the inspection object will be described with reference to the drawings.
As shown in FIG. 6, an inspection object 100 includes a case 101 that houses a main part of the instrument, a scale plate 102 that is built in the case 101, a pointer 103 that rotates on the scale plate 102, and this pointer. 103 and a lens 104 covering the scale plate 102 and a signal input unit 105 for introducing an external signal into the case 101.

An instrument supplier or an instrument receiver performs a simulation of information from the outside to the signal input unit 105 and inspects the behavior and stop position of the pointer 103. Note that, depending on the type of instrument, there is an item that takes time from when the simulation information is given until the pointer 103 is stabilized (stabilized). .
For such inspection, a flat plate inspection table is used (see, for example, Patent Document 1 (FIG. 1)).

Patent document 1 is demonstrated based on the following figure.
FIG. 7 is a diagram for explaining a conventional inspection table. The inspection table 110 is erected on a pedestal 112 placed on a floor 111 and is rotatable on the pedestal 112 as indicated by an arrow (1) around a vertical axis. The supporting shaft 113, a U-shaped frame 114 standing on the supporting shaft 113, and a rectangular frame 115 rotatably attached to the U-shaped frame 114 as indicated by an arrow (2) around a horizontal axis.

Since the rectangular frame 115 is a relatively large flat plate, three stages of inspection objects (upper inspection object 116, middle inspection object 117, lower inspection object 118) can be set on the rectangular frame 115. .
For example, during the visual inspection of the middle inspection object 117, the settling time of the upper inspection object 116 and the lower inspection object 118 can be gained.

  By the way, in order to inspect the meter installed in the instrument panel of the vehicle, the rectangular frame 115 is inclined with respect to the inclination of the instrument panel. The eye line 119 perpendicular to the rectangular frame 115 is an ideal eye line.

  Since the upper inspection object 116, the middle inspection object 117, and the lower inspection object 118 are set up and down, a healthy technician can visually observe the upper inspection object 116 in a standing posture and perform a middle inspection in a middle waist posture. Inspection can be performed by viewing the object 117 and visually inspecting the lower inspection object 118 in a bent posture.

  However, inspectors include not only healthy technicians but also technicians 120 (hereinafter referred to as wheelchair technicians) sitting in a wheelchair. It is difficult for the wheelchair technician 120 to change the posture up and down. Accordingly, the wheelchair technician 120 tilts his / her neck and visually observes the upper inspection object 116 with the upward eye line 121 and visually observes the lower inspection object 118 with the downward eye line 122.

  In the upward line 121 and the downward line 122, a geometrical deviation occurs between the scale marked on the scale plate 102 shown in FIG. As a result, the accuracy of inspection decreases.

  Therefore, an inspection table that can accurately perform an inspection even for a wheelchair technician 120 who cannot easily change the vertical posture is required.

As shown in FIG. 1, the inspection table 10 mainly includes a frame 12 fixed to the floor 11, an elevating member 20 provided on the frame 12, and an inspection object table 30 that is moved up and down by the elevating member 20. It is a component. The elevating member 20 may be provided on the inspection object mounting table 30 side and extended to the gantry 12.

  Further, “fixed” to the floor 11 means both fixing in a non-removable manner and temporarily fixing in a movable manner. If there is no concern that the gantry 12 will slip laterally during work, the gantry 12 may be simply placed on the floor 11. That is, in the present invention, all these forms are described as being fixed to the floor 11.

  The gantry 12 includes four legs 13 and a cross beam 14 that extends horizontally to the state of the legs 13.

  The elevating member 20 includes, for example, an electric motor 21, a speed reducer 22 with a power distribution function, and a plurality (two in this example) of ball screws 23. The ball screw 23 may be an electric jack integrated with a ball screw combined with a speed reducer and an electric motor. If it is an electric jack or the electric motor 21, the raising / lowering stroke can be determined by the rotation amount of the motor shaft, and the positional accuracy is improved.

The elevating member 20 may be a stepping hydraulic cylinder or a stepping pneumatic cylinder excellent in position control.
The starting and stopping of the elevating member 20 is performed by the control box 24. The control box 24 can be attached to the legs 13. On the front surface of the control box 24, an up button 25, a down button 26, and an emergency stop button 27 are provided.

  The inspection object mounting table 30 includes a rectangular plate 31, a plurality of (in this example, 3 stages × 4, 12 in total) inspection object storage units 32, and the inspection object storage unit. Support pins 33, 33 extending from the rectangular plate 31 to the front of the drawing at the lower position of 32, and a line-of-sight confirmation member (upper-stage line-of-sight confirmation member 34, middle-stage line-of-sight confirmation member) provided on the right side (or left side) of the rectangular plate 31 35 and the lower stage line confirmation member 36), and further comprises inspection start buttons 37 to 39 and inspection end buttons 41 to 43 provided on the right side (or left side) of the rectangular plate 31.

  When starting the inspection of the four inspection objects 100 stored in the inspection object storage portion 32 on the left side of the upper line confirmation member 34, the inspection start button 37 is pressed, and when the inspection is ended, the inspection end button 41 is ended. Is pressed. Similarly, the inspection start button 38 and the inspection end button 42 are operated for the inspection object on the left side of the middle stage line confirmation member 35, and the inspection object on the left side of the lower stage line confirmation member 36 is operated. The inspection start button 39 and the inspection end button 43 are operated. That is, the inspection is performed with the upper, middle, and lower stages as groups.

  The line-of-sight confirmation members 34 to 36 may be rectangular mirrors. It is desirable to draw a neutral line 44 in the center of the mirror height.

It is desirable to arrange the emergency stop button 45 also in the vicinity of the inspection start buttons 37 to 39 and the inspection end buttons 41 to 43.
The inspection object 100 (see FIG. 6) indicated by an imaginary line is supported by the support pins 33 and 33.

The inspector can raise or lower the inspection object table 30 by pressing the ascending button 25 or the descending button 26.
At this time, as shown in FIG. 2, the inspector (wheelchair technician) 48 sitting on the wheelchair 47 observes the upper stage line confirmation member 34, the middle stage line confirmation member 35, or the lower stage line confirmation member 36 before the examination. Perform lifting work.

The inspection object mount 30 is tilted following the instrument panel of the vehicle. The inspector 48 looks at the upper stage line confirmation member 34 with an ideal line of sight 49 that is straight on the inspection object mount 30.
When the upper eye line confirmation member 34 is a mirror, its own pupil is reflected on the mirror. If the pupil coincides with the neutral line 44, the line of sight 49 and the center of the mirror coincide.

The operation of the inspection table having the above configuration will be described with reference to FIGS.
As shown in FIG. 3A, the inspector 48 pays attention to the middle line-of-sight confirmation member 35, and performs an ascending operation or until the center of height (neutral line 44) of the middle-stage line confirmation member 35 overlaps his / her own line of sight 49. Perform the lowering operation. When the line of sight 49 overlaps, the lifting work is finished. The height of the neutral line 44 from the floor 11 at the end of the lifting work is defined as H1.

  Before carrying out the visual inspection, simulation information is given to the inspection object 100 shown in FIG. 3B and the pointer (FIG. 6, reference numeral 103) is rotated. When the inspection object 100 operates with an electrical signal, the simulated information is an electrical signal, and when the inspection object 100 operates with a pressure signal, the simulated information is a pressure signal. Any information can be used. That is, the simulated information may be any information that rotates the pointer, or may simply be a rotation command value of the pointer. The same applies to the inspection object 100 in FIG.

  Next, the inspector 48 moves the body to the back of the drawing. Then, as shown in (b), the inspection object 100 placed on the middle stage is visually observed. The height from the floor 11 of the attention point 51 (FIG. 6, the center of rotation of the pointer 103, etc.) of the inspection object 100 is assumed to be H2. Since H2 and H1 are set to be the same or substantially the same, the inspector 48 can visually inspect the inspection object 100 with an ideal eye line 49.

When the inspection of the inspection object 100 at the middle stage is completed, the inspector 48 raises the inspection object mounting base 30.
As shown in FIG. 4A, the inspector 48 pays attention to the lower line-of-sight confirmation member 36, and performs an ascending operation until the center of the height (neutral line 44) of the lower-stage line-of-sight confirmation member 36 overlaps with his own line of sight 49. Do. When the line of sight 49 overlaps, the lifting work is finished. The height of the neutral line 44 from the floor 11 at the end of the lifting work is defined as H3. This H3 is the same as or almost the same as H1 in FIG.

  Next, the inspector 48 moves the body to the back of the drawing. Then, as shown in (b), the inspection object 100 placed on the lower stage is visually observed. The height of the target point 51 of the inspection object 100 from the floor 11 is set to H4. Since H4 and H3 are set to be the same or substantially the same, the inspector 48 can visually inspect the inspection object 100 with an ideal line of sight 49.

Next, the advantage of the present invention moving the inspection object table up and down along the vertical axis will be described with reference to the drawings.
As shown in FIG. 5 (a), an inclined plate 131 is provided, and an inspection object mounting table 132 is provided along the inclined plate 131, and the inspection object mounting table 132 indicated by a solid line is indicated by an imaginary line with an elevating member 133 such as a cylinder. The inspection table 130 having a structure to be lowered to the position shown is used as a comparative example.
Since the inspection object stage 132 is guided by the inclined plate 131, no bending force acts on the elevating member 133. As a result, there is an advantage that the diameter of the elevating member 133 can be reduced.

  By the way, the distance between the wheelchair technician 134 and the front lower end of the specimen mounting table 132 indicated by a solid line is D1, and the distance between the wheelchair technician 134 and the front lower end of the specimen mounting base 132 indicated by an imaginary line is D2. Then, D2 becomes smaller than D1. If there is a concern about the wheelchair technician 134 coming into contact with the lower end of the front surface of the test object platform 132 indicated by the imaginary line, the wheelchair technician 134 may move the wheelchair to change the distance from D1 to D2. become. That is, in the comparative example, it is necessary to move the wheelchair laterally. In order to improve workability, the fewer the wheelchair operations, the better.

  On the other hand, in the embodiment according to the present invention, as shown in FIG. 5 (b), the inspection object mounting base 30 indicated by the solid line is lowered to the position of the imaginary line along the vertical line 52 perpendicular to the ground. The distance between the wheelchair technician 48 and the lower front end of the specimen mounting table 30 indicated by the solid line, and the distance between the wheelchair technician 48 and the lower front end of the specimen mounting base 30 indicated by the imaginary line are the same D3. . As a result, it is not necessary for the wheelchair technician 48 to move forward and backward toward the inspection object mount 30. Therefore, according to the embodiment, workability can be improved.

The eye line confirmation members 34 to 36 are suitable because the mirror is inexpensive and can be easily replaced. However, it is somewhat inaccurate. Therefore, the line-of-sight confirmation members 34 to 36 can be changed to CCD cameras. With a CCD camera, the position of the eye (pupil) of the inspector can be accurately determined by image analysis. However, the system is complex and effective.
Therefore, a mirror, a CCD camera, and other members can be adopted as the eye line confirmation members 34 to 36.

  Further, the examination table of the present invention may be used by a healthy person or a one-handed technician in addition to a wheelchair technician. However, it is particularly suitable for wheelchair technicians who are difficult to change the posture in the height direction.

  The examination table of the present invention is suitable for wheelchair technicians.
