Description

Technical Field

[0001] The utility model relates to the technical field of an automated assembly line of a laser marking machine, in particular to a feeding mechanism for a marking machine. Background Art

[0002] Laser marking is a marking method that uses high-energy-density lasers to partially irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction that changes color, thereby leaving a permanent mark. Laser marking can produce a variety of text, symbols, and patterns, and the character size can range from millimeters to microns, which is of special significance for mass customization of products. For laser marking technology, a very important application is to print patterns on products. After the product is printed with exquisite patterns, it can be combined with other accessories to form a display and placed in a designated location indoors for users to appreciate.

[0003] With the continuous development of automation technology, laser marking machines can now achieve batch printing, that is, there are multiple installation positions on the marking machine, and the robot takes and places multiple products to the processing position of the marking machine, and multiple laser heads print and process their respective products at the same time. At this time, one side of the laser marking machine is equipped with a loading mechanism, which can move the products to be processed to the specified position, and then the robot takes and places the products to be processed.

[0004] However, the existing loading mechanism mainly adopts the conveyor belt transmission method. Once the transmission distance is too long, the transfer position of the product will inevitably shift. At this time, the robot will transfer and place according to the preset program. Once the product position is shifted, it is easy to cause the robot to fail to pick up the material, which seriously affects the working efficiency of the marking machine. Utility Model Content

[0027] Reference Figure 1 As a feeding mechanism for a marking machine provided by an embodiment of the utility model, the feeding mechanism includes a silo 1, a material picking assembly and a rotating assembly 2. The silo 1 is provided with a plurality of limit chambers 11, and a plurality of plates are stacked and placed in each limit chamber 11; the material picking assembly includes a plurality of material picking suction cups, and the number of the material picking suction cups is the same as the number of the limit chambers 11. Each material picking suction cup moves to the position of the corresponding limit chamber 11 and adsorbs the plate to pick up the material; the rotating assembly 2 is located on one side of the silo 1, and includes a support seat 21, a flip plate 22 and a rotating cylinder 23. The flip plate 22 is mounted on the support seat 21 and is rotatably connected to the support seat 21. The rotating cylinder 23 drives the flip plate 22 to rotate. The support seat 21 is provided with a plurality of adsorption members 211. The number of the adsorption members 211 is the same as the number of the material picking suction cups. After the material picking suction cups move to pick up the material, the plate is placed on the flip plate 22, and the flip plate 22 rotates and throws out the excess plate.

[0028] A limiting chamber 11 is provided on the silo 1, and the sheet materials are directly stacked and placed in the limiting chamber 11. The limiting chamber 11 has a positioning effect on the sheet materials, which facilitates the material picking component to accurately pick up materials, and can effectively avoid the phenomenon that the manipulator fails to pick up materials due to the displacement of the material position. When the sheet is a lightweight material with a thin texture, due to the stacking of sheet materials, adhesion will occur between adjacent sheets, and when the material picking suction cup picks up materials, two sheet materials may be taken out at the same time. Therefore, the rotating component 2 is rotated to be used for multiple purposes, and the excess sheet materials are thrown off, which is convenient for the marking process of the sheet and improves the processing efficiency of the marking machine.

[0029] Specifically, the silo 1 is a square structure, and a plurality of limiting chambers 11 are arranged in an array on the silo 1, and each limiting chamber 11 is adapted to the size of the plate. In this embodiment, the plate material is small in volume, thin in thickness, and has a non-smooth surface. After a plurality of plate materials are stacked and placed in the limiting chamber 11, under the action of the gravity of the plate material, the closer the plate is to the bottom, the easier it is for the adjacent plates to stick together. At this time, when the material taking tray takes the material, it is easy to take out two plate materials at the same time, or to take out three plate materials at the same time. Therefore, by rotating the rotating component 2, the excess plate material is thrown off, which facilitates the marking process of the plate and improves the processing efficiency of the marking machine. A vacuum flow channel is provided in the flip disk 22, and the vacuum flow channel is connected to the adsorption component 211. A vacuum pump is provided on one side of the flip disk 22, and the vacuum pump is connected to the vacuum flow channel. The vacuum pump works, so that the suction piece 211 generates negative pressure suction, and the material picking suction cup moves to the position of the corresponding limit chamber 11 and sucks the plate to pick up the material. After picking up the material, the plate is placed on the suction piece 211 corresponding to the flip plate 22. The suction piece 211 sucks and fixes the plate on one side. If there are two or three layers, the excess plate can be thrown out as the flip plate 22 rotates. After the flip plate 22 rotates one circle and resets, the material picking suction cup moves to the flip plate 22 again to pick up the material, and transports the plate material to the designated processing position. At this time, it can effectively ensure that the plates at the processing position are all in one layer, preventing the plate materials from sticking to each other.

[0030] Furthermore, the support base 21 includes two oppositely arranged support plates 212, the flip disk 22 is mounted between the two support plates 212 and rotatably connected to the support plate 212, a mounting base 213 is fixed to one side of the support plate 212, the rotating cylinder 23 is fixed on the mounting base 213, and the output end of the rotating cylinder 23 passes through the support plate 212 and is connected to the flip disk 22.

[0031] Specifically, both ends of the flip plate 22 are provided with a rotating shaft 221, the support plate 212 is provided with a mounting hole 214 adapted to the rotating shaft 221, the rotating shaft 221 is rotatably connected to the mounting hole 214, and the output end of the rotating cylinder 23 is fixedly connected to one of the rotating shafts 221. After the rotating cylinder 23 is started, it drives the flip plate 22 to rotate. In this embodiment, the axes of the two rotating shafts 221 are located on the same straight line, and the straight line where the axes of the two rotating shafts 221 are located passes through the center of gravity of the flip plate 22. This makes the flip plate 22 more stable when rotating, and the shaking amplitude is small.

[0032] Furthermore, the feeding mechanism further comprises a collecting bin 3, which is arranged in the flipping direction of the flipping disc 22. The plate materials falling from the flipping disc 22 can be uniformly collected and processed.

[0033] Furthermore, the feeding mechanism further includes a base 4, on which the silo 1, the rotating assembly 2 and the collecting bin 3 are all fixed, and the silo 1 and the collecting bin 3 are located on both sides of the rotating assembly 2. With the above-mentioned structural arrangement, the positions of the silo 1, the rotating assembly 2 and the collecting bin 3 are relatively fixed, and no subsequent position adjustment is required.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
