Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be noted that the drawings of the present invention are simplified and use non-precise ratios, and are only used for the purpose of facilitating and clearly assisting the description of the embodiments of the present invention.

Referring to fig. 1-3, the pushing mechanism includes a pushing plate 1, a translation module 2, a lifting module 3, a mounting block 4, and a guiding assembly 5. The translation module 2 comprises a rack 21, a screw rod 22 rotatably connected to the rack 21, a nut seat 23 screwed to the screw rod 22, and a first guide rail 24 fixed to the rack 21, wherein the first guide rail 24 is slidably connected with the nut seat 23 and is arranged in parallel with the screw rod 22; the lifting module 3 comprises an air cylinder 31 fixedly connected to the top of the nut seat 23, and a piston rod of the air cylinder 31 can extend out in the vertical direction; the mounting block 4 is fixedly connected to the top end of the piston rod, at least two studs 11 penetrate through and are screwed on the mounting block 4 along the horizontal direction, the studs 11 are arranged in parallel at intervals, and the material pushing plate 1 is screwed with one end, extending out of the mounting block 4, of each stud 11; the guide assembly 5 is configured to guide the mounting block 4 such that the mounting block 4 moves in a vertical direction.

By means of the structure, in the pushing operation of the pushing mechanism, the pushing plate 1 needs to descend and translate to push workpieces to be loaded and unloaded, namely, the lifting module 3 drives the pushing plate 1 to descend, and the translation module 2 drives the screw seat 23 to translate to complete the pushing purpose. The first guide rail 24 arranged on the frame 21 can guide the nut seat 23 to stably and linearly slide, and meanwhile, the guide assembly 5 can guide the mounting block 4 to linearly move along the vertical direction, so that the material pushing plate 1 can be ensured to stably move in the horizontal direction and the vertical direction, and the material pushing operation is ensured to be smooth.
