When the first sensor 30 and the second sensor 32 sense the front and rear edges of the plate, the first material blocking mechanism 29 and the second material blocking mechanism 31 block the front and rear edges of the plate to position the plate, thereby improving the position accuracy and stability of the plate on the turnover device 3, and improving the precision and quality of the laser marking of the plate by the laser marking device 4.

The material blocking cylinder 33 is used to drive the material blocking block 34 to ascend and descend.

When it is needed to release the plate, the material blocking cylinder 33 drives the material blocking block 34 to ascend, so that the material blocking block 34 releases the blocking of the plate.

[0038] In this embodiment, both the first flip plate 6 and the second flip plate 11 are equipped with infeed / outfeed sensors 35 at their ends that are far apart from each other. In practical applications, one infeed / outfeed sensor 35 is used to sense when a plate enters the flipping device 3, and the other infeed / outfeed sensor 35 is used to sense when a plate exits the flipping device 3.

[0039] In this embodiment, the laser marking device 4 includes a longitudinal drive mechanism 36 mounted on the machine base 1, a transverse drive mechanism 37 connected to the moving end of the longitudinal drive mechanism 36, a lifting drive mechanism 38 mounted on the moving end of the transverse drive mechanism 37, a lifting plate 39 mounted on the lifting end of the lifting drive mechanism 38, a laser marking mechanism 40 mounted on the lifting plate 39, and a dust collector 41 mounted on the lifting plate 39. In practical applications, the longitudinal drive mechanism 36, the transverse drive mechanism 37, and the lifting drive mechanism 38 cooperate to drive the lifting plate 39 and the laser marking mechanism 40 to move. The laser marking mechanism 40 performs laser marking on the plate, while the dust collector 41 removes the smoke generated during laser marking.

[0040] In this embodiment, the laser marking mechanism 40 includes a housing 42 mounted on the lifting plate 39, a beam combiner 43 mounted at a 45° angle inside the housing 42, an annular light source 44 mounted on the housing 42 and located below the beam combiner 43, a laser 45 mounted on the housing 42 and located above the beam combiner 43, and a camera 46 located on one side of the beam combiner 43. The bottom surface of the housing 42 is provided with a through hole 47, and the annular light source 44 is arranged around the through hole 47. Visible light is reflected by the beam combiner 43 to the camera end of the camera 46, and the laser emitted by the laser 45 can penetrate the beam combiner 43 and the through hole 47.

[0041] In practical applications, the ring light source 44 emits light to illuminate the board, thereby illuminating the area to be laser-marked. The visible light reflected by the board is reflected by the beam combiner 43 to the camera end of the camera 46. The camera 46 can visually locate the area to be laser-marked on the board and can also record the laser marking process in real time. In addition, the laser emitted by the laser 45 passes through the beam combiner 43 and the via 47 to perform laser marking on the board.

[0042] Specifically, a dustproof and anti-fogging mirror is installed inside the via 47, which allows laser and visible light to pass through.

[0043] In this embodiment, an adjustment plate 48 is installed on the side wall of the housing 42, and the camera 46 is mounted on the adjustment plate 48. This structural design facilitates the assembly of the housing 42 and the camera 46.

[0044] In this embodiment, one end of the adjusting plate 48 has a height adjustment groove 49, and the other end of the adjusting plate 48 has a horizontal adjustment groove 50. The adjusting plate 48 is locked to the housing 42 by a first locking fastener, which passes through the height adjustment groove 49. The camera 46 is locked to the adjusting plate 48 by a second locking fastener, which passes through the horizontal adjustment groove 50. Specifically, both the first and second locking fasteners can be locking bolts. The first locking fastener is threaded to the housing 42, and the second locking fastener is threaded to the camera 46.

[0045] In practical applications, by loosening the first locking fastener, the adjusting plate 48 can be adjusted in height relative to the first locking fastener and the housing 42 along the height adjustment groove 49, thereby adjusting the shooting height of the camera 46. Since the beam combiner 43 is tilted at 45°, when the height position of the camera 46 changes, the position of the camera 46 shooting plate will also change accordingly, so as to realize the adjustable shooting position of the camera 46. After the adjustment is completed, simply tighten the first locking fastener to lock the adjusting plate 48 and the housing 42 together. Loosening the second locking fastener allows the camera 46 to move horizontally along the horizontal adjustment groove 50 to adjust the distance between the camera 46 and the beam combiner 43, thereby adjusting the focal length of the camera 46 shooting plate. After the adjustment is completed, simply tighten the second locking fastener to lock the adjusting plate 48 and the camera 46 together.

[0046] All technical features in this embodiment can be freely combined according to actual needs.

[0047] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
