[0029] Working principle:

[0030] The disk support 802 and the circuit board 801 are placed on the circuit board positioning disk 51 in turn by means of a manual or external grabbing mechanism, and the disk support 802 is placed in the positioning hole 513, and the circuit board 801 is placed on the step pin 511; the disk support 802 is positioned through the positioning hole 513, and the end of the disk support 802 abuts against the inner bottom surface of the clamping claw yielding groove 514; the circuit board 801 is positioned and supported by the cooperation of the step pin 511 and the assembly hole 804; the clamping claw cylinder 52 drives the disk support claw 53 to slide and nest in the claw yielding groove 514 to clamp the disk support 802; the linear slide 2 4 drives the slide 2 41 to move, so that the positioning bracket 5 moves to the bottom of the linear slide 1 2;

[0031] The linear slide 2 drives the slide 21 to move, and through the cooperation of the linear slide 2 and the telescopic cylinder 31, the screw suction nozzle 36 is moved to the position of the external screw supplier, and a single connecting screw 803 is sucked by the screw suction nozzle 36. Through the cooperation of the linear slide 2 and the telescopic cylinder 31, the connecting screw 803 is dipped in the glue in the colloid containing box 6 and moved to the top of the circuit board 801 for screwing; the telescopic cylinder 31 is extended to push the lifting plate 32 and the electric screwdriver 33 down. When the connecting screw 803 penetrates the circuit board 801 and abuts against the disk support 802, the screw suction nozzle 36 and the suction nozzle mounting plate 35 stop descending, and the elastic force applied by the spring 2 310 to the connecting plate 311 overcomes the elastic force applied by the spring 1 39 to the lifting plate 32, so that the lifting plate 32 continues to descend. After the screwdriver head fits the connecting screw 803 in the screw nozzle 36, the reaction force applied by the connecting screw 803 to the screwdriver head overcomes the elastic force applied by the spring 2 310 to the connecting plate 311, so that the electric screwdriver 33 stops descending, and the telescopic cylinder 31 continues to drive the guide rod 38 to descend until the stroke ends; the connecting screw 803 is screwed by the electric screwdriver 33 to connect it with the internal thread of the disk support 802, and at the same time, when the connecting screw 803 spirally descends, the elastic force applied by the spring 2 310 to the connecting plate 311 causes the electric screwdriver 33 and the screw nozzle 36 to descend synchronously until the connecting screw 803 and the disk support 802 complete the threaded connection assembly; after the assembly is completed, the linear slide 2 4 drives the slide 2 41 to move to the next assembly station for subsequent assembly processing of the circuit board component 800.

[0032] Furthermore, a groove 531 for clamping the disk pillar 802 is formed on the clamping surface of the disk pillar clamp 53, and the groove 531 is a V-shaped groove structure.

[0033] Furthermore, a plurality of positioning pins 515 are vertically provided on the top surface of the positioning bracket 5, and limiting through holes are provided on the bottom surface of the circuit board positioning disk 51 at positions corresponding to the positioning pins 515, and the circuit board positioning disk 51 is clamped on the positioning pins 515 of the positioning bracket 5 through the limiting through holes; the positioning pins 515 are clamped together with the limiting through holes on the circuit board positioning disk 51, so that the circuit board positioning disk 51 can be easily disassembled and assembled.

[0034] The circuit board and plate support assembly device of the vehicle instrument panel disclosed in this embodiment respectively positions and supports the circuit board 801 and the plate support 802 through the stepped pin shaft 511 and the positioning hole 513 provided on the circuit board positioning plate 51, drives the plate support clamp 53 to slide and nest in the clamp yielding groove 514 to clamp the plate support 802 through the clamp cylinder 52, and then threadingly connects the connecting screw 803 with the plate support 802 under the circuit board 801 through the screw driving mechanism 3, thereby completing the assembly of the plate support 802 and the circuit board 801; the impact of the connecting screw 803 on the plate support 802 is buffered by the spring 1 39, and the impact of the screwdriver head of the electric screwdriver 33 on the connecting screw 803 is buffered by the spring 2 310, and the feeding movement of the screwdriver head when screwing is realized by the spring 2 310 and the spring 1 39, so that the impact damage to the circuit board assembly 800 during assembly is small, the assembly is stable and reliable, the assembly efficiency is high, and the equipment structure is simple.
