[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 , an embodiment provided by the utility model: a high-efficiency new laser engraving machine, including a workbench 50, on which a vibration plate 20, a positioning device 10 and a laser head 30 are arranged. The vibration plate in this embodiment is a double-conveying vibration plate device, and the vibration plate 20 is connected to a double conveying channel 21. The vibration plate 20 can cooperate with the double conveying channel 21 to simultaneously transport two products. The output end of the double conveying channel 21 is connected to the positioning device 10, and the two products enter the positioning device 10. The laser head 30 is located directly above the positioning device 10. The positioning device 10 includes a baffle 2 and two propulsion cylinders 3 arranged on a frame 1. The end of the frame 1 opposite to the baffle 2 is the inlet end of the positioning device. The product enters from the inlet end of the positioning device, and the product conflicts with the baffle 3. The two propulsion cylinders 3 are located on the same side of the top of the frame 1, and the propulsion directions of the two propulsion cylinders 3 are the same. Two positioning cylinders 4 are arranged on the front and rear sides of the top of the baffle 2, and the propulsion directions of the two positioning cylinders 4 are the same. The pushing directions of the pushing cylinders 3 are perpendicular to each other, and the pushing directions of the two positioning cylinders 4 are relatively arranged. A partition 5 is arranged in the middle of the baffle 2, and the two positioning cylinders 4 are both provided with a push plate 6. After the push plate 6 and the partition 5 are close to each other, the space structure between the two forms a limit slot that runs through from top to bottom. The pushing cylinder 3 is connected with a pad 7, and the two pads 7 are pushed by the two pushing cylinders 3. The two pads 7 are respectively located under the two limit slots to carry the products. The two positioning cylinders 4 can respectively drive the two push plates 6 to push in the direction of the partition 5, and the push plates 6 and the partition 5 are close to each other to form two limit slots. The two limit slots position two products at the same time. After the positioning is completed, the products can be directly processed in the limit slots. After the processing is completed, the pushing cylinder 3 can drive the pad 7 away from the limit slots. At this time, the limit slots are connected up and down, and the products can be quickly discharged under the influence of gravity, saving work steps and improving work efficiency. The utility model has the advantages of simple structure and high work efficiency.

[0021] The frame 1 is provided with a sloped material channel 8, the input end of the sloped material channel 8 is located at the bottom of the two pads 7. After the propulsion cylinder 3 drives the pads 7 away from the limiting slot, the product enters the sloped material channel 8 under the influence of gravity. The sloped material channel 8 can buffer the product to prevent the product from falling from an excessively high distance and causing damage, and the sloped material channel 8 can have a guiding and transmission effect on the product.

[0022] Under normal conditions, the propulsion cylinder 3 is in a propulsion state, that is, the pad 7 is located above the inclined material channel 8, which facilitates the pad 7 to carry the product when the product enters the frame 1; under normal conditions, the positioning cylinder 4 is in a retracted state, that is, the push plate 6 is away from the partition 5. This setting facilitates the product to enter the frame 1 and contact with the baffle 2. After the product enters the frame 1, the positioning pneumatic 4 drives the push plate 6 to advance and perform a directional action on the product.

[0023] A mechanical arm 40 is disposed on the workbench 10 , and the laser head 30 is disposed on the mechanical arm 40 . The mechanical arm 40 drives the laser head 30 to move up, down, forward, and backward.

[0024] In this embodiment, the robot arm 40 is a dual-axis transmission module.

[0025] When the product enters either end of the frame 1, the positioning cylinder 4 at the corresponding end performs a pushing action and realizes positioning. The product is laser engraved by a laser head 30. After the processing is completed, the pushing cylinder 3 on the corresponding side drives the pad 7 to reset, so that the processed product falls into the slope channel 8 for product discharge.

[0026] An elastic structure 8 is provided on the frame 1, which is connected to the baffle 2, and the elastic direction of the elastic structure 8 is the same as the transmission direction of the propulsion cylinder 3. The elastic direction of the elastic structure 8 is opposite to the product feeding direction. When the product enters the frame 1 at high speed and contacts the baffle 2, the transmission force of the product can impact the baffle 2. If it is impacted frequently for multiple times, the baffle 2 may be displaced or even damaged, affecting the positioning effect of the positioning device. The elastic structure 8 plays a buffering role, and the elastic force of the elastic structure 8 can offset the transmission force of the product, that is, the position deviation of the baffle 2 can be reset by the elastic structure 8, thereby increasing the service life of the positioning device and ensuring the positioning effect of the positioning device.

[0027] The elastic structure 8 in this embodiment includes two guide rods, both of which are sleeved with springs, and the two springs are respectively connected to the baffle 2.

[0028] A host control screen 60 is provided on the workbench 50, and the host control screen 60 is electrically connected to the vibration plate 20, the positioning device 10, the robotic arm 40 and the robotic arm 40 respectively, and a human-computer interaction interface can be displayed on the host control screen 60, and the start and stop or parameter adjustment of the above devices can be controlled through the human-computer interaction interface.

[0029] A first curved surface 9 is provided on the inner end face of the push plate 6, and a second curved surface 12 is provided at the connection between the baffle plate 2 and the partition 5. The first curved surface 9 and the second curved surface 12 form the side faces of the limiting groove. The first curved surface 9 and the second curved surface 12 are used to adapt to the shape of the product so that the peripheral side of the product fits with the inner end face of the limiting groove to improve the positioning effect. At the same time, the push plate 6 and the baffle plate 2 can adjust the shape of the inner side faces according to the actual shape of the product.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
