DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below in conjunction with the drawings and specific embodiments.

[0031] Reference Figures 1-3 : A kind of automatic laser marking machine that can be unloaded, including shell 1, feeding device 4 and unloading device 5;The laser marking machine further includes marking device 2 and transfer device 3;Marking device 2 is arranged in shell 1 along the height direction of shell 1, and marking device 2 includes marking machine body 21, and marking machine body 21 receives workpiece 6 and marks the workpiece 6;Transfer device 3 is arranged below marking device 2, feeding device 4 and unloading device 5 are symmetrically arranged about transfer device 3 along horizontal direction, when processing, feeding device 4 pushes workpiece 6 into transfer device 3, and the workpiece in transfer device 3 is ejected into unloading device 5 after processing, transfer device 3 drives the workpiece to move to the upper part of marking device 2, and the workpiece in the upper part of marking device 2 is arranged around marking machine body 21.

[0032] The traditional laser marking machine is sequentially provided with a feeding device 4, a marking device 2 and a discharging device 5 according to the working sequence, and the area occupied by the laser marking machine is large, and the working area during feeding and discharging needs to be isolated, so more space is needed, and the space utilization is reduced. In the application, the feeding device 4 and the discharging device 5 are arranged below the marking device 2. The feeding device 4 receives the workpiece 6. The feeding device 4 puts the workpiece 6 into the transfer device 3. The transfer device 3 drives the workpiece 6 to rise. When the bottom end surface of the workpiece 6 is coplanar with the working end surface of the marking device 2, the transfer device 3 stops running. At this time, the lifted workpiece 6 is not located directly below the marking machine body 21, and needs to be rotated to the position directly below the marking machine body 21 by the marking device 2. The marking machine body 21 marks the workpiece 6. After marking, the marking device 2 drives the processed workpiece to rotate to the original position. The transfer device 3 receives the processed workpiece and drives the receiving part to descend. When the transfer device 3 stops descending, the feeding device 4 feeds. The feeding device 4 pushes the new workpiece 6 into the upper part of the transfer device 3. The processed workpiece in the transfer device 3 is pushed out by the newly pushed workpiece 6 and falls on the discharging device 5. In this way, the discharging is completed. Then the transfer device 3 drives the workpiece 6 to rise again. The feeding device 4 and the discharging device 5 are connected through the transfer of the transfer device 3, so that the feeding and discharging of the feeding device 4 and the discharging device 5 can be reduced to reduce the working range. At the same time, the feeding device 4 and the discharging device 5 are located below the marking device 2. Therefore, the feeding device 4 and the discharging device 5 no longer occupy the space around the marking device 2, and the space utilization is improved.

[0033] Referring to Figures 5-10 The marking device 2 further comprises a rotating disc 22, a driving device 23 and a receiving block 24. The rotating disc 22 is arranged around the periphery of the marking machine body 21 along the height direction of the marking machine body 21. Two through grooves 221 are vertically arranged through the upper part of the rotating disc 22 about the axis of the rotating disc 22. A clamping groove is horizontally arranged on the side wall of the through groove 221. A clamping block 222 is slidingly arranged in the clamping groove along the extension direction of the clamping groove. The clamping block 222 is driven by hydraulic pressure. The driving device 23 is arranged below the rotating disc 22. The driving device 23 drives the rotating disc 22 to rotate. The receiving block 24 is arranged in the through groove 221. The receiving block 24 is slidingly matched with the through groove 221 along the axis direction of the rotating disc 22.

The workpiece 6 is driven by the transfer device 3 to pass through the through slot 221. It is worth noting that at this time, the rotating disc 22 is in a non-rotating state, and the receiving block 24 is located at the upper part of the transfer device 3. After the workpiece 6 is pushed into the transfer device 3 by the feeding device 4, the workpiece 6 is received by the receiving block 24. The transfer device 3 drives the workpiece 6 to slide into the through slot 221 of the rotating disc 22 along the axis of the rotating disc 22 through the receiving block 24. When the transfer device 3 stops running, the hydraulic system in the rotating disc 22 is started. The clamping block 222 located in the clamping groove slides out. The sliding-out clamping block 222 is inserted into the clamping groove. Then, the transfer device 3 is separated from the receiving block 24 and descends. The first rotary driver 231 is started. The first rotary driver 231 drives the tooth ring 233 to rotate through the gear 232. Thus, the rotating disc 22 fixedly connected with the tooth ring 233 can be rotated. The rotating disc 22 drives the receiving block 24 to synchronously rotate. When the rotating disc 22 drives the receiving block 24 located in the through slot 221 to rotate to the position directly below the marking machine body 21, the rotating disc 22 stops rotating.
