Full-automatic marking device

Abstract

The invention discloses a full-automatic marking device comprising a base (7). A vertical block (8) and a press rod (9) are connected to the base (7) in a sliding manner at the same time. The verticalblock (8) and the press rod (9) are parallel. A flat plate (10) is arranged at the upper end of the press rod (9). The lower end of the press rod (9) is provided with a punch pin (11). A reset deviceis arranged between the press rod (9) and the base (7). A first connection rod (12) is rotationally connected to the base (7). The base (7) is provided with a motor used for driving the first connection rod (12) to rotate. The free end of the first connection rod (12) is rotationally connected with a rolling wheel (15) used for tightly abutting against the flat plate (10) or being disengaged fromthe flat plate (10). A second connection rod (13) is arranged between the first connection rod (12) and the vertical block (8). The full-automatic marking device can prevent marking omission and hashigher transmission reliability.

Description

technical field [0001] The invention relates to a fully automatic marking device. Background technique [0002] The automatic marking device refers to the marking on the outer wall of the processed product, such as the certification, production date, product production materials, use precautions and other identification text. Most of the marking machines in the prior art place the processed products on the conveyor belt, and send the products to the bottom of the punch with engraved characters through the conveyor belt, and the punch moves up and down periodically to mark the product under the punch. However, the product identification obtained in this way has the following disadvantages: First, because the punch moves up and down periodically, once the distance between the products on the conveyor belt is not equal, it is easy for the punch to fail to contact the product when it goes down , that is, the product cannot be accurately delivered to the bottom of the punch, so ...

Problems solved by technology

Most of the marking machines in the prior art place the processed products on the conveyor belt, and send the products to the bottom of the punch with engraved characters through the conveyor belt, and the punch moves up and down periodically to mark the product under the punch. However, the product identification obtained in this way has the following disadvantages: First, because the punch moves up and down periodically, once the distance between the products on the conveyor belt is not equal, it is easy for the punch to fail to contact the product when it goes down , that is, the product cannot be accurately delivered to the bottom of the punch, so it is easy to miss the mark; secondly, since the conveyor belt is a flexible conveying device, it means that the belt of the conveyor belt is a variable and elastic material , once the punch is in contact with the product on the conveyor belt, the conveyor belt will deform, and when the punch leaves the product, the conveyor belt will rebound to return to its original shape. In the process of deformation and rebound of the conveyor belt, The conveyor belt fluctuates; that is to say, every time the punch prints the product on the conveyor belt, the conveyor belt will fluctuate or tremble once, then the conveyor belt will cause the subsequent products to be marked to be displaced relative to the conveyor belt during the fluctuating or trembling process, that is It affects the spacing of subsequent products, and then the punch misses marking due to the fluctuation of the conveyor belt.

To sum up, the marking machine in the prior art still has the phenomenon of missed marking, and the cooperation between the conveyor belt and the punch is not reliable enough, that is, the transmission is not reliable enough.
