Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to a feeding device for laser engraving of a notebook shell. Background Art

[0002] Laser engraving machine is a device that uses laser beam to engrave on the surface or inside of a material. It is mainly used to carve permanent marks on various materials. It uses laser beam to produce physical or chemical reactions on the material, thereby engraving marks or displaying patterns and text on the surface of the material. Laser engraving machine is also called laser engraving machine or laser marking machine. Unlike traditional mechanical engraving machines, it does not require the use of high-hardness tools, but directly acts on the material through laser beams. At present, when processing notebook shells, laser engraving machines are needed to type or process pattern LOGO on the surface of the notebook shell. When using the existing feeding device for laser engraving of metal mirror surface of notebook shell, the staff needs to manually place the notebook shell on the workbench, which not only increases the workload of the staff, but also affects the work efficiency. Summary of the invention

[0003] The purpose of the present invention is to solve the problems existing in the above-mentioned background technology, and to propose a feeding device for laser engraving processing of a notebook shell.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A feeding device for laser engraving of a notebook shell comprises a bottom support seat and a feeding tray, the upper surface of the bottom support seat is tightly attached to the feeding tray, a servo motor is fixed in the middle of the bottom support seat, an electric push rod is vertically fixed to the inner front end of the bottom support seat, a discharge plate is fixed to the outer side of the upper surface of the feeding tray, a lifting plate is embedded in the middle of the discharge plate, a non-slip plate is fixed on the top of the lifting plate, an outer plate is fixed to the upper surface of the feeding tray, an adjusting bolt is embedded in the inner part of the outer plate, one end of the adjusting bolt is connected to a connecting plate, the upper and lower ends of the connecting plate close to the middle of the discharge plate are rotatably connected to rotating rollers, and a limiting belt is nested on the outer side of the rotating roller.

[0005] Preferably, the servo motor is connected to the feeding tray in a clockwise rotation via a transmission shaft, and the feeding tray rotates 90° above the bottom support seat each time.

[0006] Preferably, a discharge plate is fixed to the front, rear, left and right ends of the outer side of the upper surface of the feeding tray, and the upper surface of the discharge plate is on the same horizontal plane as the top of the anti-slip plate in the lifting plate.

[0007] Preferably, the bottoms of the four discharge plates are vertically opened with extension holes, and the top of the push rod at the output end of the electric push rod is just embedded in the extension hole of the discharge plate at the front end of the feeding tray.

[0008] Preferably, connecting plates are provided at the front, rear, left and right ends of the upper surface of the unloading plate, and the limiting belt rotates up and down in the vertical direction outside the rotating roller.

[0009] Preferably, the outer wall of the adjusting bolt is connected to the inner wall of the outer plate via a thread, and the connecting plate slides back and forth and left and right on the upper surface of the feeding tray.

[0010] When the laser engraving machine is set at the rear end or right side of the feeding tray, the servo motor drives the feeding tray to rotate 90° clockwise each time, so that the notebook shell that has not been laser engraved can be moved just under the laser engraving machine, and the laser engraving machine can engrave the notebook shell that has not been laser engraved. When the laser-engraved notebook shell moves to the front end of the feeding tray as the feeding tray rotates, the push rod above the electric push rod moves from bottom to top and will be embedded in the extension hole under the discharge plate, and then push the lifting plate up, so that the lifting plate will lift up the laser-engraved notebook shell through the anti-slip plate, which makes it more convenient for subsequent staff to replace the laptop shell, further improving the efficiency of laser engraving on the notebook shell.

[0011] 2. Before laser engraving, according to the size of the notebook shell, you can turn the adjustment bolts in the outer plate of the feed plate in turn, so that the adjustment bolts push the limit belts toward the middle of the feed plate through the connecting plate and the rotating roller to adjust the distance between the limit belts at the front, back, left and right ends of the upper surface of the feed plate, so that the notebook shell can be just embedded and tightly attached between the adjacent limit belts at the front, back, left and right ends, which can effectively prevent the notebook shell from shaking during the laser engraving process. When the notebook shell is lifted up and down between the front, back, left and right limit belts, the notebook shell will drive the limit belts to rotate together, reducing the friction between the notebook shell and the limit belts during the up and down movement, making the loading and unloading of the notebook shell smoother, and further improving the laser engraving efficiency of the notebook shell.
