Technical Field

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

[0002] A laser marking machine uses a laser beam to permanently mark various different material surfaces. The marking effect is achieved by evaporating the surface layer material to expose the deeper layer material, thereby engraving delicate patterns, trademarks, and characters. Laser marking machines are mainly divided into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and ultraviolet laser marking machines.

[0003] An existing laser marking machine with an automatic feeding mechanism (Publication No.: CN219724947U) has at least the following drawbacks: The device inputs workpieces to the conveyor belt through a storage tray, and then conveys them to the lower part of the laser marking machine through the conveyor belt for marking. However, when the conveyor belt conveys the workpieces to the lower part of the laser marking machine, the workpieces are not effectively positioned, and only the angle of the workpieces can be restricted, which affects the marking effect of the laser marking machine on the workpieces. Therefore, the present utility model is proposed. Content of the Utility Model

One end of the telescopic rod of the first cylinder 2 extends to the top surface of the conveyor 1. One end of the telescopic rod of the first cylinder 2 is fixed with a driving plate 201. A first clamping plate 202 is arranged on one side of the driving plate 201. Second clamping plates 203 are arranged on the front and rear sides of the first clamping plate 202. One side of the second clamping plate 203 is of an inclined surface structure.

[0023] As Figures 2-4As shown, in this embodiment, two sliding grooves 206 are formed on both sides of the two driving plates 201 close to each other. Two sliding frames 204 are fixed on the side of the second clamping plate 203 close to the driving plate 201. The sliding frames 204 are slidably arranged inside the sliding grooves 206. Two support rods 207 are slidably arranged on one side of the driving plate 201. One end of the support rod 207 is fixed to the side of the first clamping plate 202 close to the driving plate 201. Two directional wheels 205 are also fixed on the side of the first clamping plate 202 close to the driving plate 201. The rollers of the directional wheels 205 are in contact with the inclined surface of the second clamping plate 203. By using the feeding box 3 to push the workpieces onto the top surface of the conveyor 1 one by one, and then the conveyor 1 conveys the workpieces to the lower part of the marking machine 101. At this time, start the two first cylinders 2 to drive the two first clamping plates 202 synchronously to clamp the workpiece from the left and right sides of the workpiece. When the two first clamping plates 202 are on the left and right sides of the workpiece, the second clamping plate 203 is stressed to clamp the workpiece from the front and back sides of the workpiece, so as to realize clamping and positioning of the workpiece from four directions, which is convenient for the marking machine 101 to mark the workpiece and improve the marking effect.

[0024] As Figures 2-4 shown, in this embodiment, a feeding box 3 is fixed inside the conveyor 1. Feeding holes 301 and driving holes 302 are respectively formed on the front and back sides of the feeding box 3. A pushing plate 303 is slidably inserted into the driving hole 302. Two fixing grooves 304 are formed on the rear side of the feeding box 3. A second cylinder 305 is arranged inside the fixing grooves 304. One end of the telescopic rod of the second cylinder 305 is fixed to one side of the pushing plate 303.

[0025] As Figures 2-4 shown, in this embodiment, a support roller 4 is rotatably connected inside the sliding frame 204. The outer wall of the support roller 4 is in contact with one side inside the sliding groove 206. By the contact between the support roller 4 and one side inside the sliding groove 206, the friction generated between the sliding frame 204 and the sliding groove 206 is reduced, thereby increasing the service life of the device.

A spring 501 is fixed between the sliding frame 204 and the inner side of the sliding groove 206, and the spring 501 is movably sleeved with the outer wall of the limiting rod 5. By setting the spring 501, when the first clamping plate 202 and the second clamping plate 203 are away from the workpiece, the spring 501 can pull the sliding frame 204 to quickly reset, thereby quickly resetting the first clamping plate 202 and the second clamping plate 203, so that the workpiece is convenient for being transported away by the conveyor 1.

[0027] like Figures 2-4 As shown, in this embodiment, guide inclined plates 6 are fixed on both sides of the interior of the conveyor 1. The guide inclined plates 6 can guide the workpieces and prevent the workpieces from being obstructed by the second clamping plate 203 during transportation.

[0028] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: in use, by stacking the workpieces into the interior of the loading box 3, and then starting the second cylinder 305 to drive the pushing plate 303 to slide inside the driving hole 302, so that the pushing plate 303 pushes the workpiece on the lowest layer of the loading box 3, so that the workpiece is pushed into the conveyor 1 from the discharge hole 301, so that the workpiece is transported to the bottom of the marking machine 101, and then the pushing plate 303 is reset. At this time, under the action of gravity, the second to last workpiece falls into the lowest surface of the loading box 3, and then the two first cylinders 2 are started and synchronously drive the two first clamping plates 202 to clamp the workpiece on the left and right sides of the workpiece. When the first clamping plate 202 is attached to the workpiece and squeezed, the first clamping plate 202 moves toward the second clamping plate 203, and the supporting roller 4 squeezes the inclined surface of the second clamping plate 203. With the cooperation, the second clamping plate 203 is made to approach the front and rear sides of the workpiece, and the second clamping plate 203 and the front and rear sides of the workpiece are clamped and positioned. At this time, the sliding frame 204 slides inside the sliding groove 206 and squeezes and compresses the spring 501, and then the workpiece is clamped and positioned from four directions, thereby facilitating the marking machine 101 to mark the workpiece. By supporting the roller 4 and contacting the inner side of the sliding groove 206, the friction generated by the sliding frame 204 and the sliding groove 206 is reduced, thereby increasing the service life of the device. By setting the spring 501, when the first clamping plate 202 and the second clamping plate 203 are away from the workpiece, the spring 501 can pull the sliding frame 204 to quickly reset, thereby quickly resetting the first clamping plate 202 and the second clamping plate 203, so that the workpiece is transported away by the conveyor 1. The guide inclined plate 6 can play a guiding role on the workpiece to prevent the workpiece from being obstructed by the second clamping plate 203 during transportation.
