Among them, the gantry support 200 is arranged on the frame 100, and the driving mechanism 300 is arranged on the gantry support 200; the screwdriver 400 is connected to the driving mechanism 300, and the driving mechanism 300 is used to drive the screwdriver 400 to move in the X-axis direction and the Z-axis direction, and the X-axis direction is Figure 1 The left and right directions shown in the figure, the Z-axis direction is Figure 1The screw feeding mechanism 500 is arranged on the frame 100, and the screw feeding mechanism 500 is connected to the screwdriver 400 through the pipeline 600. The screw feeding mechanism 500 is used to deliver screws to the screwdriver through the pipeline 600; the slide rail 700 is arranged on the frame 100, and each mounting plate 800 is arranged on the corresponding slide rail 700, and can move along the slide rail 700 in the Y-axis direction, that is, the Y-axis direction Figure 1 The front-to-back direction shown in FIG. 8; the mounting plate 800 is used to place the workpiece to be processed, and the screwdriver 400 is used to screw the workpiece to be processed.

[0046] Specifically, according to the automatic screw locking device of the embodiment of the utility model, when screwing the workpiece to be processed, the workpiece to be processed is first placed on the mounting plate 800; then, the screw feeding mechanism 500 delivers the screws to the screwdriver 400 through the pipe 600; the driving mechanism 300 then drives the screwdriver to move along the X-axis direction to the position where the screws need to be screwed, and then the driving mechanism 300 drives the screwdriver 400 to descend along the Z-axis direction, so that the screwdriver 400 screws the screws into the workpiece to be processed, and then the driving mechanism 300 drives the screwdriver 400 to rise and move to the next position where the screws need to be screwed, or the slide rail 700 drives the workpiece to be processed to move along the Y-axis direction to the next position where the screws need to be screwed, and then the screwdriver 400 continues to screw the screws until the workpiece to be processed is completed. According to the automatic screw locking device of the embodiment of the utility model, screws can be automatically delivered to the screwdriver 400, and the screwdriver 400 and the workpiece to be processed can be automatically moved to the position where the screws need to be screwed, and then the screwdriver 400 automatically screws the screws, thereby improving the efficiency of screwing and saving time and labor costs.

[0047] Furthermore, if Figures 2 to 4 As shown, in some embodiments of the utility model, the screw feeding mechanism 500 includes a discharge bin 510, a rotating device 540, a conveying device 550 and a transfer device 560; wherein the discharge bin 510 is used to place screws; the rotating device 540 is arranged in the discharge bin 510, and at least one bearing plate 541 is arranged on the inner wall of the rotating device 540; one end of the conveying device 550 is passed through the rotating device 540, and the other end of the conveying device 550 is connected to the input end of the transfer device 560, and the output end of the transfer device 560 is connected to the pipeline 600. The rotating device 540 is used to drive the bearing plate 541 to rotate, so that the bearing plate 541 drives the screws in the discharge bin 510 to be transferred to the conveying device 550, the conveying device 550 is used to transport the screws to the transfer device 560, and the transfer device 560 is used to transport the screws to the screwdriver 400 through the pipeline 600.

[0048] Specifically, when the rotating device 540 rotates, driving the supporting plate 541 to rotate to the bottom of the discharge bin 510, the supporting plate 541 will carry up some screws in the discharge bin 510. When the supporting plate 541 continues to rotate to a certain height along with the rotating device 540, the screws on the supporting plate 541 will fall along the supporting plate 541 to the conveying device 550, and the conveying device 550 will transport the screws to the transfer device 560, and then the transfer device 560 will send the screws to the screwdriver 400 through the pipeline 600.

By providing two guide plates 553 at one end of the conveying device 550, when the screw falls from the bearing plate 541, the guide plates 553 can catch the screw, so that the screw slides along the guide plates 553 to the screw conveying channel 552; and by setting the guide plates 553 to be inclined from bottom to top toward the outside, the bearing area of ​​the guide plates 553 can be increased, so that the guide plates 553 can receive more screws, so that more screws fall into the screw conveying channel 552.

[0050] like Figure 4As shown, in some embodiments of the present invention, a posture adjustment device 570 is provided above the screw delivery channel 552, and the posture adjustment device 570 can swing back and forth on both sides of the screw delivery channel 552, so that the screw rod of the screw on the screw delivery channel 552 is located inside the screw delivery channel 552, and the nut of the screw on the screw delivery channel 552 is located on the surface of the screw delivery channel 552. When the screw falls from the carrier plate 541 to the screw delivery channel 552, it may have various postures, such as horizontal, vertical and oblique. If the posture of the screw is not adjusted, the subsequent transfer device 560 will not be able to smoothly deliver the screw to the screwdriver 400. To this end, a posture adjustment device 570 is provided above the screw conveying channel 552. The posture adjustment device 570 may include a brush and a swinging device for driving the brush to swing back and forth. When the screw is transported along the screw conveying channel 552, the swinging device will drive the brush to swing back and forth. If the screw happens to be vertically located in the screw conveying channel 552, that is, the screw rod of the screw is located inside the screw conveying channel 552, and the nut of the screw happens to be located on the surface of the two conveyor belts 551, the brush just fails to touch the screw, or even if the brush can touch the screw, it cannot move it; and if the screw is not vertically located in the screw conveying channel 552, for example, it is placed horizontally on the surface of the screw conveying channel 552, then the brush will move the screw out of the screw conveying channel 552 during the swinging process, and fall back into the storage bin 510, or adjust the posture of the screw so that the screw is vertically placed in the screw conveying channel 552.

[0051] like Figure 2 As shown, in some embodiments of the utility model, the screw feeding mechanism 500 also includes a transfer bin 520, a partition 530 is arranged between the discharge bin 510 and the transfer bin 520, a transfer device 560 is arranged in the transfer bin 520, and a conveying device 550 is arranged through the partition 530. A counter and a blocking device are arranged at the partition 530. The counter is used to count the screws on the conveying device 550 that pass through the partition 530, and the blocking device is used to block the screws on the conveying device from passing through the partition when the count value of the counter reaches a preset value. Specifically, the screws on the screw conveying channel 552 need to pass through the partition 530 and enter the transfer bin 520 before reaching the transfer device 560; when a screw passes through the partition 530, the count value of the counter is increased by 1, and the number of screws transmitted each time can meet the needs of the operation by counting the counter; when the count value of the counter reaches the preset value, the blocking device blocks the subsequent screws from continuing to move forward, and the blocking device can be a cylinder or other device, and the advancement of the screw is blocked by the extension of the cylinder.
