[0044] The pointer detection assembly 61 and the needle cap detection assembly 62 are both mounted on a rotating member 65, and are driven by the rotating member 65 to rotate in a circle, at least 1810°, to perform 360° detection on the pointer and the needle cap to prevent missed detection.

[0045] In this embodiment, the base 2 includes a pad 21, an adjusting pad block 22 and a panel 23. The pad 21 is fixedly mounted on the base plate 1, and the adjusting pad block 22 is detachably mounted at the four corners of the pad 21. The panel 23 is located directly above the pad 21 and is mounted on the adjusting pad block 22. The horizontal state of the panel 23 is adjusted by adjusting the pad block 22 to prevent mismeasurement caused by the unevenness of the panel 23.

[0046] In this embodiment, the movable frame 4 includes a transverse movable rail 41, a vertical rail 1 42 and a vertical rail 2 43. The bottom of the transverse movable rail 41 is fixedly installed on the base plate 1. The vertical rail 1 42 and the vertical rail 2 43 are both installed on the transverse movable rail 41 and can slide freely on the transverse movable rail 41. The vertical rail 1 42 and the vertical rail 2 43 slide back and forth on the transverse movable rail 41 to press and detect the pointer.

[0047] In this embodiment, the pressure needle head 51 includes a pressure rod 511, a slide 512, a pressure sensor 513 and a visual detector 514. The pressure rod 511 is fixedly installed on the slide 512, the slide 512 is slidably installed on the guide rail, the guide rail is fixedly installed on the fixed plate 52, the pressure sensor 513 is fixedly installed on the fixed seat, and the pressure sensor 513 is located directly above the pressure rod 511.

The probe 1 611 and the probe 2 612 are fixedly installed in a rotating member 65. The two ends of the sensing wire 613 are respectively fixed to the bottom of the probe 1 611 and the probe 2 612. There is a height difference between the probe 1 611 and the probe 2 612. A rolling ball 614 is provided at the bottom of the probe 2 612. The vertical track 1 42 drives the probe 1 611 and the probe 2 612 to move downward until the rolling ball 614 hits the instrument panel. The rotating member 65 drives the probe 1 611 and the probe 2 612 to rotate, and the sensing wire 613 located between the two is moved downward. The induction wire 613 rotates in a circle following the rotating member 65. The initial position of the induction wire 613 is set at the end of the instrument panel numbers. It rotates from the end to the front end. After rotating the angle formed by all the numbers on the instrument panel, the position of the pointer is determined based on the touch with the pointer. For example, the speedometer is 0-180km / h, and the sector angle of the sector-shaped digital table from the number 0 to the number 180 is 270°. Then the induction wire 613 will rotate forward from the position of the end 180 on the instrument panel. After rotating 270°, it is determined whether the pointer points to the zero position based on the touch position. If the pointer is not touched at the zero position, the pointer needs to be adjusted. If the pointer is touched at a position not reaching the zero position, it also needs to be adjusted.

[0049] In this embodiment, the needle cap detection assembly 62 includes a laser reflector 1 621, a laser emitter 2 622 and a reflective detection plate 623. The laser reflector 1 621 and the laser emitter 2 622 are both fixedly mounted in the rotating member 65. The reflective detection plate 623 is fixedly mounted in the cover plate 624. The cover plate 624 is fixedly mounted in the protective cover 63. The needle cap is irradiated by the laser reflector 1 621 and the laser emitter 2 622. If the needle cap is installed flatly and does not exceed the set error range, the reflection generated by the irradiated laser will be reflected on the reflective detection plate 623. If the flatness of the needle cap installation exceeds the error range, part of the generated laser reflection will not be on the reflective detection plate 623, and it can be judged that the needle cap is not flat enough.

[0050] In this embodiment, the rotating member 65 includes a rotating column 651, an electrical connector 652, a limit assembly 66 and a servo 653. The top of the rotating column 651 is fixedly connected to the electrical connector 652, the upper part of the electrical connector 652 is fixedly connected to the limit assembly 66, the top of the limit assembly 66 is fixedly connected to the servo 653, and the servo 653 is fixedly installed on the mounting plate 64. The servo 653 is used to drive the rotating column 651 to rotate, and the electrical connector 652 is used to fix probe 1 611 and probe 2 612.

[0051] In this embodiment, the limit assembly 66 includes an adapter column 661, a limit block 662 and a baffle 664. The adapter column 661 is connected between the electrical connector 652 and the output shaft of the servo 653 and is fixed to the mounting plate 64 through a mounting frame plate. The limit block 662 is arranged on the side wall on the opposite side of the adapter column 661. The baffle 664 is detachably mounted on the protective cover 63 through a connecting handle 665. The two side surfaces of the baffle 664 are respectively used to provide limits for the limit block 662. The curvature of the baffle 664 is set according to the angle of the instrument panel. If the above-mentioned angle is 270°, the angle of the baffle 664 is set to 60° here for limiting.

[0052] Working principle: When in use, first fix the instrument panel on the clamp 3, then press the pointer onto the installation position of the instrument panel through the movable pressure rod 511, then remove the pressure rod 511, move the pointer re-inspection component 6 above the pointer, press down until the ball 614 rests on the panel of the instrument panel, and drive the rotating column 651 to rotate through the servo 653, and at the same time drive the probe 1 611, the probe 2 612, the laser reflector 1 621, and the laser emitter 2 622 to rotate, so that the sensing wire 613 follows the rotating part 65 to make a circular rotation, and the position of the pointer is judged according to the contact with the pointer, and the needle cap is irradiated by the laser reflector 1 621 and the laser emitter 2 622, and the flatness of the needle cap is judged according to the reflection state.

[0053] Based on the above, the invention can detect the indicated position of the pointer after it is installed on the instrument panel through the set pointer detection component, thereby preventing the pointer from pointing to the zero position; the needle cap detection component in the invention determines whether the needle cap is correctly placed on the instrument panel through the set laser and the reflection generated on the needle cap, thereby preventing the needle cap from tilting.
