[0002] In the last step after product processing, some marks such as the manufacturer and product model are generally engraved on the product by laser. However, the existing laser engraving is generally carried out by manually taking and placing the product at a designated position. Since the product needs to be fixed at the designated position, it is not convenient to put the product into or take it out from the designated position, and the employee is also easily irradiated by the laser, resulting in hand injuries. In view of the above problems, a solution is proposed below. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fully automatic laser engraving structure, which has the advantage of automatically realizing the feeding and discharging of products in the laser engraving area.

Detailed implementation

[0020] The following description is only the preferred implementation of the present invention, and the protection scope is not limited to this embodiment. All technical solutions falling within the concept of the present invention shall fall within the protection scope of the present invention. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom" and "top", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0021] As Figures 1 to 4 shown, a fully automatic laser engraving structure includes a first frame 1, a second frame 2, a feeding mechanism and a positioning mechanism. There is a gap between the output end of the positioning mechanism and the output end of the feeding mechanism, and this gap is the engraving area. The feeding mechanism includes a first cylinder 4, a feeding push plate 5 and a position adjustment block 6. The first cylinder 4 is fixed on the upper end surface of the first frame 1. A slot is provided on the lower side surface of one end of the position adjustment block 6, and the position adjustment block 6 is sleeved on the output shaft of the first cylinder 4 from top to bottom through the slot. The feeding push plate 5 is located on the second frame 2. An adjustment column 7 is provided at one end of the feeding push plate 5, and the adjustment column 7 is detachably connected to the position adjustment block 6. Therefore, after the first cylinder 4 is started, it can push the feeding push plate 5 to move on the upper end surface of the second frame 2 in the horizontal direction.

[0022] A sleeve groove is provided on the position adjustment block 6, and the sleeve groove is sleeved on the adjustment column 7 from top to bottom. Engagement teeth are provided on the two side walls of the adjustment column 7 and the two inner walls of the sleeve groove. After the sleeve groove is sleeved on the adjustment column 7, the two parts of the engagement teeth are engaged with each other, so that there is no sliding between the sleeve groove and the adjustment column 7 in the horizontal direction. According to the width of the product 14, the depth of the adjustment column 7 extending into the sleeve groove can be changed, so that it can adapt to products 14 of various specifications.

[0023] The positioning mechanism includes a second cylinder 8 and a positioning block 9. The second cylinder 8 is longitudinally fixed on the side wall of the second frame 2. The output shaft of the second cylinder 8 is fixedly connected to one end of the positioning block 9. A positioning cavity is provided on the second frame 2. The positioning block 9 is located in the positioning cavity and is slidably connected to the positioning cavity. The second cylinder 8 can drive the positioning block 9 to move up and down along the positioning cavity, so that the positioning block 9 can be in two positions: an initial position and a working position. In the initial position, the top end of the positioning block 9 is flush with the upper end surface of the second frame 2; in the working position, the positioning block 9 moves upward, and the top end of the positioning block 9 protrudes above the upper end surface of the second frame 2.

[0024] On the side wall of the second rack 2, there is a positioning groove. On one side of the positioning block 9, a limiting block 10 is fixedly arranged. The limiting block 10 is located in the positioning groove and is slidably connected to the positioning groove. The limiting block 10 will move along with the positioning block 9. When the limiting block 10 moves to the uppermost end of the positioning groove, neither the limiting block 10 nor the positioning block 9 can move upward any further. At this time, the positioning block 9 is in the working position. In the initial position, the limiting block 10 is located at the lowermost end of the positioning groove.

[0025] On both sides of the second rack 2, there are baffles 11. In this design, the length of the baffle 11 on one side of the second rack 2 is shorter. At the shorter baffle 11, there is a stop block 12. There is a gap between the stop block 12 and the shorter baffle 11, and this gap is the feeding port 3. External equipment sends the product 14 to the feeding port 3 and moves it to the upper end face of the second rack 2 through the feeding port 3. The baffle 11 can prevent the product 14 from falling off the second rack 2.

[0026] The width of the stop block 12 is greater than the width of the baffle 11. One side of the feeding push plate 5 abuts against the side wall of the baffle 11, and the other side of the feeding push plate 5 abuts against the side wall of the stop block 12. In this design, the length of the working position is equal to the length of two products 14, and the length of the contact surface between the feeding push plate 5 and the product 14 is also equal to the length of two products 14. That is, the device can laser-engrave two products 14 at a time. After processing is completed, the two products 14 are pushed out by the feeding push plate 5. The length of the contact surface between the stop block 12 and the product 14 is equal to the length of one product 14. The position where the stop block 12 is located can be regarded as the area where the product 14 to be processed is located. The product 14 in the waiting area presses against the two products 14 in the processing positions, preventing the two products 14 in the processing positions from shifting to one side, so that the two products 14 in the processing positions can be accurately engraved.

[0027] On one of the baffles 11, an upper abutting block 13 is fixedly arranged. The lower end surface of the upper abutting block 13 abuts against the upper end surface of the feeding push plate 5. The upper abutting block 13 is used to limit the feeding push plate 5 to make the feeding push plate 5 move smoothly.

[0028] Working principle: When feeding the product 14, first, the second cylinder 8 is started to drive the positioning block 9 to move upward to the working position. Then, the external product 14 moves from the feeding port 3 to the engraving area on the upper end face of the second rack 2. When two products 14 move to the engraving area and one product 14 moves to the area to be processed, the first cylinder 4 is started to push the feeding push plate 5 close to the positioning block 9. The feeding push plate 5 and the positioning block 9 cooperate to clamp the two products 14 located in the engraving area. Then, the external laser engraves the two products 14.

[0029] After the engraving is completed, the second cylinder 8 drives the positioning block 9 to move downward to the initial position. The first cylinder 4 continues to push the feeding push plate 5 forward, so that the feeding push plate 5 pushes the two products 14 out of the engraving area. Finally, the first cylinder 4 drives the feeding push plate 5 to move back until the feeding push plate 5 moves out of the engraving area. After that, the subsequent products 14 to be engraved will enter the engraving area again for processing.

[0030] The specific embodiments described above further elaborate on the technical problems solved, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
