Detailed Description

The application provides an automatic laser marking device which is particularly suitable for workpieces, such as shaft sleeves or sleeve parts, which are small in size, hollow cylinders in appearance and need to be marked on end surfaces. As shown in fig. 3, in the present embodiment, the workpiece 900 has a hollow cylindrical shape with a diameter of about 10mm and an axial length of about 25mm, and is required to be marked on the end face 901, but the position of the mark in the circumferential direction of the end face 901 is not limited in general.

In order to mark such workpieces 900, the workpieces 900 need to be positioned first, but because of the small size of the workpieces 900, it is inconvenient to mark after positioning the workpieces 900 one by one as in the prior art. Therefore, the method of arranging the plurality of workpieces 900 on the tray 200 is adopted to improve the feeding efficiency, and the tray 200 can be moved gradually along the direction of the array when marking is performed, repeated positioning of the positions of the workpieces 900 is not needed, and marking efficiency is improved. In addition, after the workpieces 900 on the whole tray 200 are marked, the tray 200 can be directly moved, so that the blanking efficiency is improved. In summary, the positioning of the workpiece 900 by the tray 200 in the present application improves the loading and unloading efficiency and the marking efficiency. In addition, the tray 200 has the advantage of being convenient to move relative to the smaller volume of the workpiece 900, so that the workpiece 900 can be easily and controllably handled, and positioning during marking is facilitated.

As shown in fig. 3, the tray 200 includes a substantially rectangular edge 210, a plurality of straight extending connection bars 220 arranged in a well shape or a grid shape are formed in the edge 210, an intersection point is formed between the transverse connection bars 220 and the longitudinal connection bars 220, pins (not shown) extending vertically upwards are arranged at the intersection point, the diameters of the pins are slightly smaller than the inner diameter of the workpiece 900, and when the tray is installed, the workpiece 900 is inserted on the pins, so that the workpiece 900 is ensured to be positioned on the tray 200.

Further, in order to facilitate stacking of the trays 200, the bottom of the tray 200 is formed with a storage tank recessed upward, so that when the upper and lower trays 200 are stacked, the work 900 in the lower tray 200 is received in the storage tank of the upper tray 200 without interference with the upper tray 200. Specifically, the connecting strip 220 is located at the middle of the height direction of the edge 210, so that the connecting strip 220 is located at a distance from the bottom of the tray 200, thereby forming the storage tank. Furthermore, since the connecting bar 220 is located in the middle of the height direction of the edge 210, a storage area recessed downward is formed above the tray 200, so that the workpiece 900 will be located in the storage area, the area of the upper portion of the workpiece 900 exposed outside the tray 200 is shortened, and stacking of the trays 200 is facilitated.

In addition, in order to facilitate the handling of the tray 200, the opposite sides (e.g., the left and right sides in fig. 3) of the tray 200 are provided with outwardly protruding connection plates 230, and in use, the tray 200 can be moved smoothly by grasping the connection plates 230 on both sides. Specifically, the connection plate 230 is a flat plate extending in a horizontal direction and disposed at an upper end of the rim 210, and the connection plate 230 is generally integrally formed on the rim 210.

The marking station 102 is internally provided with a material tray fixing device 500 for fixing the material tray 200, a laser marking device 600 which is arranged above the material tray fixing device 500 and used for marking the workpieces, and a material moving adjusting device 700 which is arranged on the material tray fixing device 500 and used for moving the material tray 200 along the horizontal direction so that the laser marking device 600 can mark the workpieces 900 at different positions on the material tray 200. The blanking device 800 is arranged in the blanking station 103, the blanking device 800 is used for collecting the material tray 200 passing through the marking station 102, and the output end of the blanking device 800 has a degree of freedom of moving longitudinally so as to adjust the height of the material tray 200, so that the subsequent material tray 200 can enter the blanking station.

In addition, in order to carry the tray 200, a feeding device 400 is provided at the rear side of the table, and the feeding device 400 includes: the first manipulator 410 and the second manipulator 420 are distributed left and right, the first manipulator 410 and the second manipulator 420 are used for clamping the material tray 200 at corresponding positions, the first manipulator 410 and the second manipulator 420 are arranged on the output end of the feeding mechanism 430, the output end of the feeding mechanism 430 has the degree of freedom of horizontal translation and the degree of freedom of vertical translation, the feeding mechanism 430 drives the first manipulator 410 to move back and forth between the feeding station 101 and the marking station 102, and the second manipulator 420 is driven to move back and forth between the marking station 102 and the blanking station 103 in the same time.

The using process of the equipment is as follows: first, a group of (e.g., 10) trays 200 are stacked together and placed in the loading device 300, and the height of the output end of the loading device 300 is adjusted so that the height of the uppermost tray 200 is approximately the same as that of the first manipulator 410; then the first manipulator 410 clamps the tray 200 located at the uppermost part of the feeding device 300, and at the same time, the second manipulator 420 clamps the tray 200 located in the marking station 102; the feeding mechanism 430 drives the first manipulator 410 and the second manipulator 420 to move upwards for a certain distance, so that the clamped tray 200 moves upwards and is separated independently; then, the feeding mechanism 430 drives the first manipulator 410 and the second manipulator 420 to move rightward simultaneously, so that the first manipulator 410 enters the marking station 102, the second manipulator 420 enters the blanking station 103, then the feeding mechanism 430 drives the first manipulator 410 and the second manipulator 420 to move downward simultaneously for a certain distance, the first manipulator 410 puts the corresponding tray 200 into the tray fixing device 500, and the second manipulator 420 puts the corresponding tray 200 into the blanking device 800; the feeding mechanism 430 drives the first manipulator 410 and the second manipulator 420 to reset; the laser marking device 600 marks the end face 901 of the workpiece 900 in the material tray 200, and the material moving adjusting device 700 continuously adjusts the position of the material tray 200 relative to the laser marking device 600, so that the workpieces 900 at different positions in the material tray 200 are marked one by one; after all the workpieces 900 are marked, the feeding device 400 repeats the above process, places a new tray 200 into the marking station 102, and feeds the tray 200 originally located in the marking station 102 into the blanking station 103.

The beneficial effects of this equipment are as follows: because a plurality of workpieces 900 are arranged in the tray 200 in an array, the workpieces 900 can be carried and positioned only by moving the tray 200 with a larger volume, thereby facilitating loading and unloading of the workpieces 900 and improving loading and unloading speed. Secondly, because the contact pin is arranged in the material tray 200, the workpiece 900 is positioned in the material tray 200 through the contact pin, so that the position of the workpiece 900 can be realized by adjusting the position of the material tray 200 during marking, and the workpiece 900 adopts an array setting mode, so that the position of the workpiece 900 is more conveniently controlled through the material tray 200, and the positioning accuracy of marking is improved. Compared with the prior art adopting the direct positioning of the workpiece 900, the workpiece 900 positioning mode through the tray 200 solves the problem that the prior art cannot carry small-sized workpieces.
