[0034] The flow guide assembly 8 includes a movable tube 801 installed on one side of the connecting tube 705. A notch 606 is provided on one side of the movable tube 801 close to the connecting tube 705. The movable tube 801 is sleeved and connected with the channel 605.

[0036] The driving component 3 includes a protrusion 301 installed at one end of the side plate 603, a guide rail 302 is installed on the outer wall of the protrusion 301, and a power component 303 is connected to one side of the guide rail 302. The power component 303 is used to drive the guide rail 302 to move;

[0037] The movable shaft 602 is formed by sleeves and shafts, and the outer walls of the shaft and the sleeve are provided with overflow holes 6021. The diameter of the overflow hole 6021 on the shaft is smaller than that of the overflow hole 6021 on the sleeve. The two movable shafts 602 are horizontally distributed in the control board 601. The overflow hole 6021 on the left is located on one side of the vertical center line of the movable shaft 602, and the edge of the overflow hole 6021 on the right coincides with the vertical center line of the movable shaft 602.

[0038] The notch 606 on one side of the movable tube 801 and the notch 606 on one side of the channel 605 are located at different heights, and the connecting tube 705 and the notch 606 on one side of the movable tube 801 are located at the same height.

[0039] The working principle of the present invention is as follows: the conveyor belt 1 is located on both sides of the inspection fixture, the instrument panel moves to the area where the inspection fixture is located through the conveyor belt 1, a driving component 3 is arranged inside the inspection fixture, the power assembly 303 drives the guide rail 302 to reciprocate along the vertical direction of the control panel 601, the guide rail 302 is movably connected to the side plate 603 through the protrusion 301, so that during the movement of the power assembly 303, the side plate 603 is under the action of the guide rail 302 in the active state, and the two side plates 603 both make reciprocating deflection motion with the movable shaft 602 connected to themselves as the center of the circle, When the left side plate 603 is deflected to the area where the conveyor belt 1 is located, the left side plate 603 clamps the dashboard on the conveyor belt 1 during the rotation. When the left side plate 603 rotates to be parallel to the right side plate 603, the left side plate 603 contacts the dashboard, and the right side plate 603 takes over the clamping of the dashboard. Finally, when the right side plate 603 contacts the conveyor belt 1 on the adjacent side, the right side plate 603 contacts the dashboard, and the dashboard falls onto the conveyor belt 1, and the dashboard leaves with the conveyor belt 1.

[0040] When the left side plate 603 moves away from the conveyor belt 1 on the adjacent side, the left side plate 603 contacts the dashboard on the conveyor belt 1. At this time, the movable shaft 602 connected to the left side plate 603 starts to work, and the inner axis of the movable shaft 602 and the overflow hole 6021 opened on the outer wall of the shaft sleeve start to coincide with each other. The air pump 2 is connected through the overlapping area between the overflow holes 6021 and the channel 605 inside the side plate 603 and the main plate 604.

[0041] Under the action of the air pump 2, the splint 901 is in contact with the instrument panel through the rubber pad 903. The splint 901 is deflected under the action of the spring shaft 902. The splint 901 is deflected according to the shape of the outer wall of the instrument panel, so that the splint 901 can achieve an adaptive effect according to the shape of the outer wall of the instrument panel. The instrument panel closes the opening at one end of the movable tube 801, causing the movable tube 801 to start moving relative to the side plate 603 under a negative pressure state. The movable tube 801 slides along the outer wall of the channel 605 until the movable tube 801 shrinks to the upper limit. At this time, the notch 606 on the outside of the movable tube 801 and the channel 605 is at the same height as the connecting tube 705. The movable tube 801 and the channel 605 overlap with the connecting tube 705. The air pump 2 extracts air from the groove 607.

[0042] One side of the groove 607 is connected to the air outlet of the instrument panel, and the position of the air outlet coincides with the position of the groove 607. Since the air in the groove 607 is constantly extracted by the air pump 2, the outside air continuously supplies the groove 607 to generate airflow. The airflow passes through the air outlet of the instrument panel. The integrity of the air outlet of the instrument panel affects the stability of the airflow passing through the air outlet. The outside air enters the groove 607 through the column tube 701. During the airflow passing through the column tube 701, the airflow contacts the movable block 704 inside the column tube 701. Due to the integrity of the air outlet of the instrument panel, the airflow of the column tube 701 passing through each area in the groove 607 has a strength difference. The movable block 704 moves in the through hole 702 in the column tube 701 under the action of the strong airflow. Under the action of the strong airflow, the movable block 704 squeezes the touch panel 703 on one side, thereby causing the touch panel 703 to fit with the inner wall of the column tube 701, and a passage is generated between the touch panel 703 and the column tube 701, so that the inspection component 7 can detect the connected instrument panel.

[0043] During the detection of the instrument panel, the left side panel 603 synchronously drives the instrument panel to deflect until the side panel 603 drives the instrument panel to reach a vertical state relative to the control panel 601. At this time, the right side panel 603 is parallel to the left side panel 603 and the instrument panel. At this time, the airflow inside the movable shaft 602 connected to the left side panel 603 is disconnected, and there is no overlap area between the axis of the movable shaft 602 and the overflow hole 6021 of the shaft sleeve. However, the movable shaft 602 inside the right side panel 603 is connected, and there is an overlap area between the axis of the movable shaft 602 and the overflow hole 6021 of the shaft sleeve. The grabbing component 9 on one side of the left side panel 603 is disconnected from the instrument panel, and the grabbing component 9 on one side of the right side panel 603 grabs the instrument panel after the disconnection, thereby realizing the movement of the instrument panel from the left side panel 603 to the right side panel 603, and the instrument panel follows the deflection of the right side panel 603 to realize the turning over of the instrument panel. The inspection fixture can be used in conjunction with other inspection equipment to detect the surfaces of both sides of the instrument panel.

[0044] While the instrument panel follows the movement of the right side plate 603, the inspection component 7 inside the right side plate 603 inspects the instrument panel again;

[0045] The instrument panel moves along with the right side panel 603 to the right conveyor belt 1. At this time, the airflow inside the movable shaft 602 connected to the right side panel 603 is disconnected, and there is no overlapping area between the axis of the movable shaft 602 and the overflow hole 6021 of the sleeve. The instrument panel loses contact with the right side panel 603, and the instrument panel leaves along with the right conveyor belt 1.
