[0002] Laser marking machine uses laser beam to mark permanently on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to carve out exquisite patterns, trademarks and words. Laser marking machine is mainly divided into CO2 laser marking machine, semiconductor laser marking machine, fiber laser marking machine and YAG laser marking machine. Laser marking machine is mainly used in some occasions that require more fineness and higher precision.

However, the force of the push plate pushed by the cylinder is difficult to control, and it causes indentations or deformations on products with poor hardness, thereby lowering the quality rate of the marking machine. For this reason, a UV laser marking machine with precise positioning is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0027] A travel groove 101 is provided at the middle of the upper end of the casing 100, and a bidirectional screw rod 102 is rotatably installed inside the travel groove 101. Two sets of sliding sleeves 103 are sleeved on the outer wall of the bidirectional screw rod 102. The upper ends of the two sets of sliding sleeves 103 are fixedly connected to the piston cylinder 110. A piston sheet 114 is provided in the sliding sleeve of each set of piston cylinder 110. The end of the piston sheet 114 is provided with a piston rod 111 extending out of the outside of the piston cylinder 110. The outer wall of the piston rod 111 is sleeved with a telescopic spring 113. The two ends of the telescopic spring 113 are respectively fixed to the outer wall of the piston rod 111 and the end of the telescopic spring 113. A pushing plate 112 is fixed to one end of the piston rod 111 away from the piston sheet 114, and the left and right outer walls of the two groups of piston cylinders 110 are connected with telescopic air pipes 115. The ends of the telescopic air pipes 115 extend into the moving frame 120 and are connected with piston cylinders 2 116. Each group of piston cylinders 2 116 is provided with an extension rod 117 extending out of the outside of the piston cylinders 2 116. One end of the extension rod 117 is located in the piston cylinders 2 116 and is provided with a piston block 119. The end of the extension rod 117 away from the piston block 119 is rotatably provided with a flexible baffle 118, and the other end of the flexible baffle 118 is rotatably connected to the piston cylinders 2 116.

[0028] The workpiece to be processed is placed on the upper surface of the housing 100, and an external force is applied to the bidirectional screw rod 102 to make the two sets of sliding sleeves 103 relatively close to each other along the stroke groove until the two sets of pushing plates 112 contact the left and right edges of the workpiece. At this time, the piston cylinder 110 continues to move toward the side close to the workpiece, and the piston plate 114 pushes the air inside the piston cylinder 110 into the telescopic air pipe 115, and finally enters the piston cylinder 2 116 on both sides, driving the piston block 119 to push the extension rod 117 to gradually extend out of the piston cylinder 2 116, so that the flexible baffle 118 rotates around the contact point with the piston cylinder 2 116 until it contacts the corner of the workpiece, thereby achieving the effect of limiting the four corners and both sides of the workpiece, while avoiding deformation and indentation caused by excessive contact force with the workpiece.

[0029] Please refer to Figure 1 and Figure 5A sliding groove 128 for the moving frame 120 to slide is provided on the upper surface of the casing 100, a sliding block 121 is provided at the contact position between the bottom end of the moving frame 120 and the sliding groove 128, a plurality of cavities are provided inside the two ends of the sliding block 121, a plurality of telescopic springs 122 are provided in the cavities at both ends of each group of sliding blocks 121, a ball 123 is provided at one end of each group of telescopic springs 122 at the contact position with the outer wall of the sliding groove 128, semicircular grooves matching the size of the ball 123 are provided at the contact positions between the two ends of the inner wall of the sliding groove 128 and the ball 123, and the semicircular grooves are distributed in an array along the inner wall of the travel groove 101.

[0030] When adjusting the piston cylinder 116 to adapt to the azimuth protection of different workpieces, the sliding block at the bottom of the movable frame 120 can slide back and forth along the sliding groove 128, and when sliding, the ball 123 can engage with the semicircular grooves on both sides of the inner wall of the sliding groove 128 to achieve the sliding adjustment of the up and down position of the piston cylinder 116.

[0031] Please refer to Figure 1 and Figure 6 One end of the bidirectional screw rod 102 is fixedly installed in the stroke groove 101 through a bearing, and the outer wall of the casing 100 is provided with a hand crank that penetrates into the stroke groove 101 and is connected to one end of the bidirectional screw rod 102, and the surface of the hand crank is provided with a rubber layer.

[0032] Rotating the hand crank can cause the bidirectional screw rod 102 to rotate, thereby causing the sleeve 103 to slide.

[0033] Please refer to Figure 6 A sliding block 124 fixed to one end of the piston cylinder 116 is provided in the cavity of the moving frame 120 , and a fixing rod 125 is sleeved inside the sliding block 124 .

[0034] Please refer to Figure 1 The piston cylinder 116 connected to the slider 124 slides to the left and right sides along the fixed rod 125 passing through the inside of the slider 124.

[0035] Please refer to Figure 6 The outer wall of the moving frame 120 is provided with a toggle rod 126 fixed to the outer side of the slider 124 , and the toggle rod 126 is provided with a locking bolt 127 extending to the contact position on the surface of the fixed rod 125 .

[0036] By rotating the locking bolt 127 forward and backward, the tail end of the locking bolt 127 can be brought into contact with and separated from the outer wall of the fixing rod 125, thereby achieving the position adjustment and fixing of the piston cylinder 116.

[0037] When in use, the workpiece to be processed is placed on the upper surface of the housing 100, and an external force is applied to the bidirectional screw rod 102 to make the two sets of sliding sleeves 103 relatively close to each other along the sliding groove 128, until the two sets of pushing plates 112 contact the left and right edges of the workpiece, at this time, the piston cylinder 110 continues to move to the side close to the workpiece, and the piston plate 114 pushes the air inside the piston cylinder 110 into the telescopic air pipe 115, and finally enters the inside of the piston cylinder 2 116 on both sides, driving the piston block 119 to push the extension rod 117 to gradually extend out of the outside of the piston cylinder 2 116, so that the flexible baffle 118 rotates around the contact point with the piston cylinder 2 116 until it contacts the corner of the workpiece, thereby achieving the effect of limiting the four corners and both sides of the workpiece, while avoiding the situation where the contact force with the workpiece is too large to cause deformation and indentation;

[0038] The positions of the two groups of movable frames 120 on the upper surface of the casing 100 can be controlled according to the size of the workpiece. When adjusting the position, the two groups of movable frames 120 are pulled relatively away from the sliding groove 128 opened along the upper surface of the casing 100. At this time, the sliding block 121 slides in the sliding groove 128, and the semicircular groove blocks the ball 123, so that the ball 123 squeezes the telescopic spring 122 into the cavity, and as the sliding block 121 slides along the inside of the sliding groove 128 until it enters the other group of semicircular grooves, the moved movable frame 120 is positioned, so that the device can adapt to workpieces of different sizes for laser marking operations.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
