In the present embodiment, the worktable 100 is provided with a slide rail 430, the clamping assembly 410 is slidably engaged with the slide rail 430, and the clamping driving mechanism 420 can drive the clamping assembly 410 to move back and forth along the slide rail 430 to move the clamping assembly 410 to the assembling position or move away from the assembling position.

Through setting up positioner 400, can guarantee the stability of product 020 when its mounted position to the assembly of screw is convenient for. Through the setting of centre gripping subassembly 410, can realize the fixed of product 020 simply stably. And the clamping assembly 410 can be moved to conveniently avoid the conveying path of the product 020.

The working principle of the screw assembling device 010 provided by the embodiment is as follows:

the conveying device 200 conveys the product 020 to the assembly position through the conveying belt 220, and the jacking mechanism jacks up the product 020 at the assembly position so that the product 020 is separated from the conveying belt 220. The conveyor belt 220 continues to run at this point, but the product 020 stays in the assembled position. The positioning device 400 drives the clamping assembly 410 to the assembly position by the clamping driving mechanism 420, and then the clamping driving member 414 drives the clamping portion 413 to clamp the product 020. Then, the lifting mechanism of the assembling device 300 drives the assembling components to move downwards, the lower end of the assembling rod 340 pushes the screw into the screw hole of the product 020, the screwing driving member 330 drives the assembling rod 340 to rotate by a certain angle (or the torque is increased to a preset value and then stops), so that the screw is assembled on the product 020, and then the lifting mechanism lifts the assembling components. When a new screw is to be loaded into the socket, the lower end of the mounting rod 340 is moved upwardly relative to the sleeve 324 by the first driving member 312 above the feed opening 326, at which time the screw can be loaded into the sleeve 324 through the feed opening 326. After the screws are assembled, the clamp assembly 410 is loosened and removed from the assembled position.
