Description

Technical Field

[0001] The utility model relates to the technical field of laser marking, in particular to a pushing mechanism for laser marking. Background Art

[0002] The laser marking mechanism uses a laser beam to mark the surface of various materials permanently. The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, icons and texts. When using the laser marking mechanism, a pushing mechanism is required to load and unload the material.

[0003] Publication number CN 219005001 U discloses a push mechanism for a laser marking device, including a base, a fixed seat is fixedly connected to the upper end face of the base, a laser is fixedly installed on the lower end face of the fixed seat, an auxiliary processing device is fixedly installed on the upper end face of the base, a conveyor belt is arranged on one side of the auxiliary processing device, a material storage frame is arranged on one side of the base, and a material guide plate is arranged between the material storage frame and the auxiliary processing device. In the practical new model, the electronic device to be marked is transmitted by the set conveyor belt, and the conveyor belt performs intermittent feeding. The electronic device to be marked slides into the working chamber, and the set distance sensor can occasionally detect whether the feeding is carried out. After the distance sensor detects the electronic device to be marked, it transmits a signal to the control module, and then the control module starts the laser to mark it.

[0004] However, the pushing mechanism has the following shortcomings: when the device is in use, it can achieve the effect of automatic feeding by using a rotatable workbench and a pushing plate together. However, the workbench often drives the object to be marked to move when it rotates, causing the object to be marked to move to different positions on the workbench, resulting in differences in the marking area, affecting the overall aesthetics of the marking.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Working principle: When in use, the first motor 16 is started, and the first motor 16 drives the driven gear 15 meshing with it to rotate through the driving gear 17, and the driven gear 15 drives the two movable plates 12 threadedly connected thereto to move, and the two movable plates 12 move away from each other until the push rod 13 pushes against the extrusion plate 10 and moves one end distance.

The distance sensor on the laser marking device 23 detects the object and then performs the marking operation. After the marking is completed, the first motor 16 is started again to make the push plate 14 push the object to move, push it into the collection box 24 to complete the collection, and then the next round of marking can be carried out.
