The tightening device 3 is arranged behind the nailing device 2, the Z-axis drive 5 is screwed and installed behind the tightening device 3, the X-axis drive 4 is screwed and installed behind the Z-axis drive 5, and the Y-axis drive 1 is screwed and installed on both sides of the X-axis drive 4. When the utility model is in use, the screws are first put into the hopper 26, the feeding component 21 will feed the screws into the conveying component 24, the screws will be neatly arranged and sent to the receiving component 23, the receiving component 23 will send the nails to the nail placing component 331, and then the charge coupled element 31 cooperates with the light-emitting component 32 to determine the tightening position, and the tightening device 3 is aligned with the threaded hole through the X, Y, and Z axis driving, and the screw gun 334 will screw the screw into the threaded hole to complete the automatic tightening.

[0028] In a specific embodiment, Figure 3The nailing device 2 includes a feeding component 21, a housing 22, a receiving component 23, a conveying component 24, an electric control component 25 and a hopper 26. The housing 22 is provided with an electric control component 25, and the feeding component 21 is provided on the left side. The hopper 26 is provided above the feeding component 21, and the conveying component 24 is provided behind the hopper 26. The receiving component 23 is connected to the rear of the conveying component 24. The feeding component 21 pushes the screws in the hopper 26 into the conveying component 24 through pneumatic control, and the screws are sent to the receiving component 23 through the conveying component 24. The electric control component 25 is used to control the operation of the entire nailing device 2.

[0029] Based on the previous embodiment, Figure 4 The conveying component 24 includes a material return component 241, a mounting component 242, an arranging component 243, a slideway 244 and a leveling component 245. The mounting component 242 is arranged behind the hopper 26, and the slideway 244 is screwed on the mounting component 242. The arranging component 243 is arranged below the end of the slideway 244, and the leveling component 245 is arranged above the slideway 244. The material return component 241 is arranged in front of the leveling component 245. Because the device is to tighten two kinds of screws at the same time, when the screws enter the slideway 244, the material return component 241 will push different screws back into the hopper, the arranging component 243 uses an electromagnet to arrange the screws neatly and control the speed of entering the material receiving component 23, and the leveling component 245 can control the height of the screws entering and level the screws.

[0030] In a specific embodiment, as shown in FIG. 5 , the tightening device 3 includes a charge coupled element 31, a light emitting component 32, a tightening component 1 33, a tightening component 2 34 and a mounting plate 35. The front of the Z-axis drive 5 is screwed with a mounting plate 35, the front of the mounting plate 35 is screwed with a tightening component 2 34, the right side of the tightening component 2 34 is screwed with a tightening component 1 33, the tightening component 1 33 has the same structure as the tightening component 2 34, the right side of the tightening component 1 33 is provided with a light emitting component 32, the top of the light emitting component 32 is provided with a charge coupled element 31, and the right side of the charge coupled element 31 is screwed with a mounting plate 35.

When tightening is required, the nail placing assembly 331 will send the screw to the bottom of the screw gun 334. At this time, the lifting assembly 335 descends, and squeezes the buffer assembly 332 while squeezing the screw on the threaded hole. The function of the buffer assembly 332 is to prevent the screw from shifting. After the screw is pressed, the screw gun 334 operates to screw the screw into the threaded hole. The positioning assembly 333 is used to determine the lifting height of the tightening component 33.
