[0025] Reference Figures 1 to 4 As shown, an automatic assembly mechanism for handles and feet is provided, including a frame 1, a guide rail 2 fixedly mounted on the frame 1, a fixed frame 3 and a sliding frame 4 mounted on the guide rail 2, an automatic electric screwdriver 5 fixedly mounted on the top of the fixed frame 3 and the sliding frame 4, and a liftable installation clamp 6 mounted below the two automatic electric screwdrivers 5. A control box 7 is fixedly mounted on the bottom of the frame 1 and is connected to the automatic electric screwdrivers 5.

[0026] In this embodiment, the control box 7 controls the switching of the entire mechanism. A guide rail 2 is fixed on the frame 1. A fixed frame 3 and a sliding frame 4 that can slide along the length of the guide rail 2 are fixedly installed on the guide rail 2. The sliding frame 4 can be moved by rotating the handwheel 20 to adjust the distance between the fixed frame 3 and the sliding frame 4. At the same time, the first cylinder 32 and the second cylinder 42 can be used to raise and lower the two mounting clamps 6 until the handle feet placed on the mounting clamps 6 are fixed. The handle feet are first sleeved on both ends of the handle tube and then placed on the mounting clamps 6. After being fixed, the screws are tightened by the automatic electric screwdriver 5 to achieve rapid assembly, ensure product quality requirements, and improve assembly efficiency. It is more advantageous for products that require multiple screws to assemble.

[0027] In one embodiment of this utility model, the fixing frame 3 is fixedly mounted on the guide rail 2. The fixing frame 3 includes a fixing column 31 and a first cylinder 32. The first cylinder 32 is fixedly mounted at the bottom of the fixing column 31. The telescopic end of the first cylinder 32 is connected to the bottom of the mounting clamp 6. An automatic electric screwdriver 5 is fixedly mounted on the top of the fixing column 31. Activating the first cylinder 32 can move the mounting clamp 6 mounted on the fixing frame 3 up and down until the automatic electric screwdriver 5 tightens the screws on the handle foot and the handle tube.

[0028] In one embodiment of this utility model, the sliding frame 4 is movably mounted on the guide rail 2. The sliding frame 4 includes a sliding column 41 and a second cylinder 42. The second cylinder 42 is fixedly mounted on the bottom of the sliding column 41. The telescopic end of the second cylinder 42 is connected to the bottom of the mounting clamp 6. Another automatic electric screwdriver 5 is fixedly mounted on the top of the sliding column 41. Activating the second cylinder 42 can move the mounting clamp 6 mounted on the sliding frame 4 up and down until the automatic electric screwdriver 5 on the sliding frame 4 can tighten the screw.

[0029] Furthermore, an adjustment assembly is provided at the bottom of the sliding column 41. The adjustment assembly includes an adjustment rod 10, a handwheel 20, and a connector 30. The connector 30 is fixedly installed at the bottom of the sliding column 41. The connector 30 is connected to the handwheel 20 through the adjustment rod 10. The handwheel 20 is rotatably installed on the outside of the frame 1. One end of the adjustment rod 10 is connected to the handwheel 20, and the other end of the adjustment rod 10 passes through the bottom of the fixed frame 3 and is connected to the connector 30. Rotating the handwheel 20 can adjust the distance between the sliding frame 4 and the fixed frame 3, which is suitable for various usage scenarios. For example, when the handle tubes are of different lengths, the handwheel 20 can be rotated to adjust the distance between the two frames, thereby completing the screw-locking work.

[0030] In one embodiment of this utility model, the mounting clamp 6 includes a guide plate 61 and a fixing plate 62. The fixing plate 62 is connected to the guide plate 61 via a connecting post 63. The guide plate 61 is positioned above the fixing plate 62. A groove 621 is provided on the side of the fixing plate 62 near the guide plate 61. A soft material auxiliary component 622 is provided on the groove 621. The telescopic end of the cylinder is connected to the fixing plate 62. When the telescopic end of the cylinder needs to extend, the fixing plate 62 rises along the length direction of the connecting post 63, and vice versa. A limit block is also provided on the fixing plate 62. The limit block is located between the fixing plate 62 and the guide plate 61 to prevent the telescopic end of the cylinder from extending too much, thereby damaging the handle feet. The hardness of the soft material auxiliary component 622 is less than that of the handle feet, effectively protecting the handle feet from damage during the fixing process. At the same time, the soft material auxiliary component 622 can also be disassembled and replaced.

[0031] Furthermore, the guide plate 61 has two guide holes 611, and guide posts 612 can be detachably installed in the two guide holes 611. The guide posts 612 can be extended into the position where screws need to be installed on the handle foot. The automatic electric screwdriver 5 can be directly inserted with the screws to lock them. The two guide holes 611 are different in size, which can be used for various application scenarios. If the guide post 612 is damaged, it can be removed and replaced separately.

[0032] In one embodiment of this utility model, a fine-tuning component is provided on the top of both the fixed frame 3 and the sliding frame 4. The fine-tuning component is connected to the automatic electric screwdriver 5. The fine-tuning component includes a clamping block 91, a first connecting block 92, and a horizontal adjustment plate 93. A second connecting block 94 is fixedly connected to one side of the horizontal adjustment plate 93. The second connecting block 94 is connected to a telescopic device 95 to allow the automatic electric screwdriver 5 to move up and down. The clamping block 91 is fixedly connected to the automatic electric screwdriver 5. The clamping block 91 is connected to the horizontal adjustment plate 93 through the first connecting block 92. The two clamping blocks 91 clamp the automatic electric screwdriver 5 and fix it. The clamping block 91 is connected to the horizontal adjustment plate 93 through the first connecting block 92. The horizontal adjustment plate 93 is provided with a long slot. By adjusting the position of the first connecting block 92 on the horizontal adjustment plate 93, the horizontal position of the automatic electric screwdriver 5 can be adjusted accordingly, thereby performing horizontal fine-tuning of the automatic electric screwdriver 5. The telescopic device 95 is connected to the second connecting block 94 and can adjust the height of the automatic electric screwdriver 5 up and down. The telescopic device 95 can be a cylinder or a manually operated device.

[0033] In one embodiment of this utility model, a foot pedal 8 is provided at the bottom of the frame 1, and the foot pedal 8 is connected to the control box 7.

[0034] Operating principle and steps of the automatic assembly mechanism with handles and feet: Place the handles and feet on the mounting fixture 6, start the equipment, the mounting fixture 6 presses the handles and feet, step on the foot pedal 8, adjust the distance between the two frames, the cylinder drives the mounting fixture 6 to rise and fall, so that the automatic electric screwdriver 5 can tighten the screws, after tightening, return to the original position, release the mounting fixture 6, and remove the workpiece.
