[0022] like Figures 1 to 4 As shown, this embodiment provides an automatic frame adjusting machine, including a distance adjusting mechanism 1, the distance adjusting mechanism 1 includes a slide plate 11 and a first driver 12, the first driver 12 is connected to the slide plate 11 and drives the slide plate 11 to move in a horizontal direction;

[0023] The slide plate 11 is provided with an unlocking mechanism 2, which is used to unlock the movable edge relative to the frame;

[0024] The four corners of the skateboard 11 are respectively provided with a hook mechanism 3, each of which includes a second driver 31 and a displacement sensor 32. The output end of the second driver 31 is connected to a hook 33, and the second driver 31 drives the hook 33 to hook the movable edge. The end of the hook 33 is slidably connected with a spring 34, one end of the spring 34 is arranged opposite to the detection end of the displacement sensor 32, and the other end of the spring 34 is arranged opposite to the fixed edge.

[0025] The distance adjustment mechanism 1 also includes a mounting frame 13, on which a sliding rod 14 is horizontally fixed, and a slide plate 11 is slidably connected to the sliding rod 14, and a nut 15 is fixed to the slide plate 11; a first driver 12 is mounted on the mounting frame 13, and an output end of the first driver 12 is connected to a screw rod 16 adapted to the nut 15, and the screw rod 16 is arranged parallel to the sliding rod 14.

[0026] The unlocking mechanism 2 includes a third driver 21 and a clamping finger 22. The clamping finger 22 is fixedly connected to the output end of the third driver 21. The third driver 21 drives the clamping finger 22 to move in the vertical direction. The unlocking mechanism 2 also includes a mounting plate 23 fixed on the slide plate 11. A slider 24 is fixed on the clamping finger 22. A slide rail 25 matching the slider 24 is provided on the mounting plate 23. The slide rail 25 extends in the vertical direction. The third driver 21 is installed on the mounting plate 23. The clamping finger 22 is C-shaped, and the end of the clamping finger 22 is rotatably connected to a roller 26. Specifically, lock buckles are respectively provided at the four corners of the movable edge, and a set of unlocking mechanisms 2 are provided one by one with the lock buckles, which can ensure smooth unlocking of the movable edge.

[0027] The displacement sensor 32 is a spring self-reset type, and a fourth driver 35 is provided on the hook 33. The output end of the fourth driver 35 is matched with the spring 34, and the fourth driver 35 drives the spring 34 to approach or move away from the hook 33. Under normal circumstances, when the fourth driver 35 is working, the spring 34 and the hook 33 are kept in close contact, and when working, the fourth driver 35 is loosened to allow the spring 34 to bounce away.

[0028] The end of the hook mechanism 3 is provided with a connecting conveyor platform 4, and the conveying direction of the connecting conveyor platform 4 is set horizontally and perpendicular to the action direction of the first driver 12. When manual or automated equipment moves the material frame to the input end of the connecting conveyor platform 4, the connecting conveyor platform 4 will move the material frame to a position facing the end of the hook mechanism 3, that is, the adjustment station. After the adjustment is completed, the connecting conveyor platform 4 will output it.

[0029] Specifically, the automatic frame adjusting machine of the present utility model further includes a machine shell 5. The distance adjusting mechanism 1, the unlocking mechanism 2, the hook mechanism 3, and the connecting conveying table 4 are all arranged inside the machine shell 5. The machine shell 5 is provided with corresponding material outlets and inlets, and is integrated with a controller. Preferably, the distance adjusting mechanism 1, the unlocking mechanism 2, the hook mechanism 3, and the connecting conveying table 4 are in a group, and two groups are arranged vertically inside the machine shell 5, making the corresponding automated production line more compact (refer to Figure 5 as shown).

[0030] The specific working principle of the present utility model is as follows: First, the distance adjusting mechanism 1 works. The first driver 12 drives the lead screw 16 to rotate. Under the driving action of the nut 15, the slide plate 11 translates relative to the slide rod 14, so that the unlocking mechanism 2 and the hook mechanism 3 on the slide plate 11 approach the outer side of the movable edge together until the clamping finger 22 touches the lock catch. Then the hook mechanism 3 works. The second driver 31 drives the hook 33 to hook the inner side of the movable edge. At the same time, the third driver 21 drives the clamping finger 22 to operate and unlock the lock catch, so that the movable edge can slide freely. Then the distance adjusting mechanism 1 works to make the slide plate 11 translate relative to the slide rod 14, thereby pushing the movable edge closer to the fixed edge. At this time, the fourth driver 35 acts to make the elastic piece 34 pop open and be in a detection state. The distance adjusting mechanism 1 continues to work, and the elastic piece 34 will first touch the fixed edge, thereby triggering the displacement sensor 32 to detect the distance. According to the actual detection data of each displacement sensor 32, the actual deviation of each corner is obtained, and it is judged whether it is tilted or skewed, and it is corrected or not according to the actual situation. Finally, the distance adjusting mechanism 1 works in the reverse direction. After moving the movable edge to the specified distance, the unlocking mechanism 2 and the hook mechanism 3 both move to their original positions, and the width adjustment process of this material frame is completed. Until the next material frame is input to the connecting conveying table 4, the above actions are repeated, and so on, and the width adjustment process of the material frame can be carried out continuously.

[0031] The above shows and describes the basic principles, main features, and advantages of the utility model. Those skilled in the art of this industry should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the utility model.
