[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. It should be noted that the drawings of the present invention are all simplified and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0025] See also Figure 1 and Figure 2A material pushing device is shown, which comprises a base plate 1, a first slide plate 2, a second slide plate 3, a push rod 4, a driving mechanism 5 and an elastic buckle 6. The base plate 1 has a pushing end 11 and a reset end 12 opposite to each other; the first slide plate 2 and the second slide plate 3 are arranged in parallel and juxtaposed, and are both slidably connected to the base plate 1, and the second slide plate 3 is located on the side of the first slide plate 2 facing the pushing end 11; the push rod 4 is fixedly connected to the first slide plate 2 and extends to the side of the second slide plate 3 facing the pushing end 11; the driving mechanism 5 is configured to drive the second slide plate 3 to slide toward the pushing end 11; the elastic buckle 6 is connected between the first slide plate 2 and the second slide plate 3.

[0026] By means of the above structure, when working, the driving mechanism 5 drives the second slide plate 3 to move from the reset end 12 toward the push end 11. Under the connection of the elastic buckle 6, the second slide plate 3 will drive the first slide plate 2 to move synchronously toward the push end 11, so that the push rod 4 fixed to the first slide plate 2 can push the workpiece to move from the loading position to the processing position. When the workpiece is pushed down to the limit position, it will not be able to move further, that is, the push rod 4 and the first slide plate 2 fixedly connected to the push rod 4 will not be able to move further. Since there is still a certain distance between the second slide plate 3 and the workpiece at this time, under the drive of the driving mechanism 5, the second slide plate 3 still has a movement trend toward the workpiece. When the potential energy of the movement trend is greater than the disengagement force threshold of the elastic buckle 6, the elastic buckle 6 separates, and the second slide plate 3 separates from the first slide plate 2, preventing the first slide plate 2 and the push rod 4 from applying an excessive push force to the workpiece, thereby effectively preventing the workpiece from being pushed and deformed.

[0027] Specifically, in this embodiment, the elastic buckle 6 includes a hook 61 arranged on the first slide plate 2 and a roller 62 arranged on the second slide plate 3, and the hook 61 is elastic so as to be able to engage with the roller 62, or to disengage from the roller 62 when a preset elastic deformation occurs.

[0028] It is understandable that, based on the hardness of the workpiece, the elastic buckle 6 with different release force thresholds can be selected and adapted.

[0029] In this embodiment, a pair of parallel slide rails 13 are provided on the surface of the substrate 1, and the slide rails 13 extend between the push end 11 and the reset end 12, and the first slide plate 2 and the second slide plate 3 are both slidably connected to the slide rails 13 through sliders. The reset end 12 of the substrate 1 is provided with a baffle 14 that can stop the first slide plate 2 to prevent the first slide plate 2 from sliding out.

[0030] Optionally, a pair of the elastic clips 6 are provided, and the pair of the elastic clips 6 are symmetrically connected to two sides of the first slide plate 2 and the second slide plate 3 .

[0031] Optionally, the push rod 4 is vertically connected to the first slide plate 2, and the second slide plate 3 is provided with a slot for passing the push rod 4, so that the first slide plate 2 and the second slide plate 3 can form a guiding function to maintain parallel movement through the slot.

[0032] Furthermore, the driving mechanism 5 includes a motor 51, a fixed end of the motor 51 is fixedly connected to the substrate 1, and its axial direction is perpendicular to the substrate 1, a rocker rod 52 is provided at the end of the rotating shaft of the motor 51 along the radial direction of the rotating shaft, a roller 53 extending along the axial direction of the motor 51 is provided at the end of the rocker rod 52, and a slide groove is provided on the side of the second skateboard 3 facing the motor 51, the slide groove extends along the length direction of the second skateboard 3, and the roller 53 is inserted into the slide groove.

[0033] With the above structure, during operation, after the shaft of the motor 51 rotates to disengage the elastic buckle 6, the second slide plate 3 moves toward the pushing end 11 to the extreme position, and then moves toward the reset end 12 along with the rocker arm 52 and merges with the first slide plate 2 again, so that the elastic buckle 6 is reset.

[0034] Those skilled in the art may make various changes and modifications to the invention without departing from the spirit and scope of the invention. Thus, if these modifications and variations of the invention fall within the scope of the claims of the invention and their equivalents, the invention is also intended to include these modifications and variations.
