[0032] The product 60 is conveyed to one side of the scanning device 20 and the tightening device 30 by the conveying device 10, and the product 60 is lifted upward from the conveying device 10 by the lifting mechanism 40. When lifted to a suitable position, the first fastener 71 on the outer surface of the product 60 is scanned by the scanning device 20, and the loosened first fastener 71 is found and recorded; the product 60 is rotated along the track surface by driving the rotating mechanism 50; and the second fastener 72 on the side surface of the product 60 is reinforced by the tightening device 30.

The screw floating height detection device can timely detect the loosened first fastener 71 on the upper surface of the product 60, and tighten the second fastener 72 on the side surface of the product; avoid the quality risk of the product 60 caused by the problem of the loosening of the first fastener 71 and the second fastener 72 not being discovered in time, so as to improve the reliability and stability of the product 60.

[0034] See also Figures 2 to 5The tightening device 30 includes an X-axis tightening bracket 31 fixed on the conveying device 10 and in the same conveying direction as the conveying device 10; an X-axis first guide rail 311 is provided on the X-axis tightening bracket 31, and a Y-axis tightening bracket 32 ​​is slidably provided on the X-axis first guide rail 311; a Y-axis first guide rail 321 is provided on the Y-axis tightening bracket 32, and the track direction of the X-axis first guide rail 311 and the Y-axis first guide rail 321 are perpendicular, and a Z-axis tightening bracket 33 is slidably provided on the Y-axis first guide rail 321; a Z-axis first guide rail 331 is provided on the Z-axis tightening bracket 33, and the track direction of the Z-axis first guide rail 331 is perpendicular to the track direction of the Y-axis first guide rail; a Z-axis first guide rail 331 is slidably provided on the Z-axis first guide rail 331 There is a support seat 34, on which a driving motor 35 is installed, and the rotor of the driving motor 35 is connected to a tightening assembly 36; the X-axis tightening bracket 31, the Y-axis tightening bracket 32 ​​and the Z-axis tightening bracket 33 are all provided with a driving cylinder for driving the Y-axis tightening bracket 32, the Z-axis tightening bracket 33 and the support seat 34; the X-axis tightening bracket 31, the Y-axis tightening bracket 32 ​​and the Z-axis tightening bracket 33 move along the X-axis, Y-axis and Z-axis directions respectively, so as to achieve precise positioning of the tightening assembly 36 in three-dimensional space; and then the driving motor 35 on the support seat 34 is driven to provide power for the tightening assembly 36, so that it screws on the second fastener 72 loosened on the product 60 and completes the tightening operation. Through the setting of the guide rails of the X-axis, Y-axis and Z-axis, the tightening assembly 36 can move freely in three-dimensional space, so that it can accurately reach the second fastener 72 at different positions on the outer surface of the product 60, and meet various complex assembly requirements.

[0035] See also Figure 2 , Fig. 9 and Fig.10The tightening assembly 36 includes a mounting seat 360 connected to the rotor of the driving motor 35, a mounting seat guide rail 361 is provided on the mounting seat 360, a tightening member 362 is slidably provided on the mounting seat guide rail 361, a limit plate 363 extends upward from the mounting seat 360, the limit plate 363 and the tightening member 362 are penetrated by a screw 364, a spring 365 is sleeved on the screw 364 between the tightening member 362 and the limit plate 363, a nut 366 is screwed on the free end of the spring 365, so that the limit plate 363 and the tightening member 362 are connected as a whole; a contact sensor 367 is also provided on the mounting seat 360, the contact sensor 367 penetrates the limit plate 363 and abuts against the tightening member 362.
