After placing the automotive instrument panel, the air blowing nozzle 44 is then moved to the position closest to the fixed fixture 3. The air blowing joint 41 is opened to blow hot air around the automotive instrument panel, facilitating the rapid drying of the applied fluorescent liquid and preventing its flow, which may cause errors in observation.

[0041] In this embodiment, the cross beam 6 is a horizontal moving slide rail. A vertical moving slide rail 61 driven by a motor is further provided on the cross beam 6. A needle pressing device mounting plate 62 is provided on the vertical moving slide rail 61. The position of the lower pressing head 712 is changed by the cross beam 6 and the vertical moving slide rail 61.

[0042] In this embodiment, the lower pressing part 71 includes a seat plate 711, a lower pressing head 712, a lower pressing seat 713, and a touch switch 714. The seat plate 711 is installed on the needle pressing device mounting plate 62. The lower pressing seats 713 are all installed in the lower pressing block 715. The lower pressing head 712 is connected to the lower pressing seat 713 by a spring. Limiting blocks 716 are provided on both side surfaces of the top of the lower pressing head 712. The limiting blocks 716 are slidably mounted in the corresponding limiting grooves on the lower pressing block 715. The lower pressing seat 713 is fixedly installed in the lower pressing block 715. The touch switch 714 is installed on the outer side surface of the lower pressing head 712. A touch block installed on the outer side surface of the lower pressing seat 713 is provided directly above the touch switch 714. After the position of the lower pressing head 711 is determined, the lower pressing head 712 is driven by the vertical moving slide rail 61 to move downward to press the pointer. When pressing down, the spring will be compressed first, causing the spring to be compressed under force. At this time, the limiting blocks 716 move upward in the limiting grooves. After moving to the highest position of the limiting grooves, the touch switch 714 contacts the touch block. Since the touch switch is electrically connected to the coating application part, the coating application part 72 will start to work. Among them, the lower pressing block 715 is rotatably installed in the canning box 725. When the canning box 725 rotates, the lower pressing block 715 will remain stationary and will not rotate along with it.

[0043] In this embodiment, the smearing part 72 includes a rotating shaft 721, a pressing push rod 722, a secondary rotating shaft 723, a smearing liquid tank 724 and a canning box 725. The rotating shaft 721 is installed on the seat plate 711. The pressing push rod 722 is installed above the smearing liquid tank 724 through an adapter seat 726. The rotating shaft 721 can be driven by a motor to rotate freely. The rotating shaft 721 and the secondary rotating shaft 723 are connected by gear transmission. The secondary rotating shaft 723 and an adapter ring 727 below the adapter seat 726 are connected by gear transmission. The smearing liquid tank 724 is installed in the canning box 725. The coating canning box 725, the adapter seat 726 and the adapter ring 727 are fixedly connected. The adapter ring 727 is installed on the seat plate 711 through a support 728 and can rotate freely in the support 728. After the touch switch 714 is powered on, it controls the motor connected to the rotating shaft 721 to start and drive the rotating shaft 721 to rotate. Through the transmission of gears, the adapter ring 727 drives the entire smearing part 72 to rotate. Since the pressing push rod 722 is connected to the smearing liquid tank 724, the fluorescent liquid in the smearing liquid tank 724 will be continuously pressed out and then smeared on the pointer cap. The entire smearing part 72 driven by the rotating shaft 721 rotates by an angle of 180°.

[0044] The smearing liquid tank 724 includes two identical tanks arranged side by side. The liquid outlet end at the bottom of the smearing liquid tank 724 is connected to a smearing nozzle 729 arranged on the side of the pressing head 712 through a pipeline. The lowest end of the smearing nozzle 729 is higher than the lowest end of the pressing head 712. The inner side of the smearing nozzle 729 closely adheres to the outer side of the pressing head 712 and a guiding ring 7210 is arranged between them. When the pressing push rod 722 presses down, the fluorescent liquid in the smearing liquid tank 724 will be squeezed out through the smearing nozzle 729 and smeared on the pointer cap under the rolling of small balls at the end of the smearing nozzle 729. Since the position of the smearing nozzle 729 is fixed and the smearing nozzle 729 rotates around the pressing head 712, the smearing nozzle 729 will smear the fluorescent liquid on the top surface of the pointer cap and form a complete ring during the rotation. At this time, if the pointer is installed flat, then observing these fluorescent liquids will be a uniform and continuous complete circle. If the pointer is not flat, then the width of the ring-shaped fluorescent liquid smeared will be uneven and discontinuous.

[0045] In this embodiment, the flatness detection device 8 includes a laser irradiator 81, a protective plate 82, a cleaning slide rail 83 and a cleaning wheel 84. The laser irradiator 81 is installed on the special-shaped plate 86 through a mounting stand 85. The special-shaped plate 86 is installed on the seat plate 711. The protective plate 82 is installed on the mounting stand 85 and is located below the laser irradiator 81. A protective sleeve 821 is also provided on the protective plate 82 directly below the lens of the laser irradiator 81. The cleaning slide rails 83 are arranged in parallel and symmetrically on both sides of the protective sleeve 821. Both ends of the cleaning wheel 84 are respectively connected to the sliding components on the cleaning slide rails 83. After the above-mentioned needle pressing and smearing are completed, by setting the laser irradiator 81 to irradiate the fluorescent liquid, the smearing state of the fluorescent liquid can be observed better, and accordingly, it can be judged whether the pointer is installed flatly. The provided cleaning wheel 84 can wipe off the fluorescent liquid after the observation is completed.

[0046] Working principle: When in use, first load the fluorescent liquid into the smearing liquid tank 724, and then place the vehicle dashboard on the fixed fixture 3. The balance assembly 31 is set to judge and adjust the position of the vehicle dashboard so that it is correctly placed on the fixed fixture 3. Then, change the position of the pressing head 712 through the cross beam 6 and the vertical moving slide rail 61. After the position of the pressing head 711 is determined, drive the pressing head 712 to move downward through the vertical moving slide rail 61 to press the pointer tightly. When pressing down, the spring will be compressed first, so that the spring is compressed under force. At this time, the limit stop block 716 moves upward in the limit groove. After moving to the highest point of the limit groove, the touch switch 714 contacts the touch block, controlling the motor connected to the rotating shaft 721 to start and drive the rotating shaft 721 to rotate. Through the transmission of the gears, the adapter ring 727 drives the entire smearing part 72 to rotate. Since the pressing push rod 722 is connected to the smearing liquid tank 724, the fluorescent liquid in the smearing liquid tank 724 will be continuously pressed out, and then extruded through the smearing nozzle 729 and smeared on the needle cap of the pointer under the rolling of the small ball at the end of the smearing nozzle 729. Since the position of the smearing nozzle 729 is fixed and the smearing nozzle 729 rotates around the pressing head 712, the smearing nozzle 729 will smear the fluorescent liquid on the top surface of the needle cap of the pointer and smear it into a complete ring during the rotation process. After the above-mentioned needle pressing and smearing are completed, by setting the laser irradiator 81 to irradiate the fluorescent liquid. At this time, if the pointer is installed flatly, then observing these fluorescent liquids will be uniform and continuous whole circles. If the pointer is not flat, then the width of the smeared ring-shaped fluorescent liquid will be uneven and discontinuous.

[0047] Based on the above, the invention can press the pointer on the vehicle dashboard onto the vehicle dashboard through the provided pressing head, and the provided spring can also play a buffering role to protect the pointer; in the invention, the coating part can coat the fluorescent liquid on the top of the cap part of the pointer when the needle pressing is completed, and through subsequent laser irradiation, it can be easily observed by the human eye. By observing the deformation of the coated fluorescent liquid with the human eye, it can be further determined whether the pointer is tilted.

[0048] As is known by technical common sense, the present invention can be implemented by other embodiments that do not deviate from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not the only ones. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
