[0034] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] Reference Figure 1 , Figure 2 and Figure 5 The utility model provides an embodiment: a visual positioning automated laser marking machine, comprising a marking machine body 1, a bracket 2 is fixedly connected to the workbench of the marking machine body 1, the cross-section of the bracket 2 is concave, the rear end of the bracket 2 is fixedly connected to a motor 3, the inner wall of the bracket 2 is rotatably connected to a rotating wheel 4, the middle diameter of the rotating wheel 4 is larger than the diameters of the front and rear ends, the number of the rotating wheels 4 is set to two, the two rotating wheels 4 are respectively arranged on the inner walls of the left and right ends of the bracket 2, the rotating shaft of the left rotating wheel 4 is fixedly connected to the output shaft of the motor 3, the output shaft of the motor 3 passes through the inner wall of the bracket 2, the two rotating wheels 4 are connected by a conveyor belt 5, and the conveyor belt 5 contacts the outer wall of the larger diameter area in the middle of the rotating wheel 4.
[0036] Reference Figure 3 , Figure 6 and Figure 8 A stabilizing component 6 is provided inside the bracket 2, and the stabilizing component 6 includes a slide groove 61. The shape of the slide groove 61 is consistent with the shape of the conveyor belt 5. The width of the end of the slide groove 61 on the inner side of the bracket 2 is narrower than the end of the slide groove 61 on the outer side of the bracket 2. A slide rod 62 slides on the inner wall of the slide groove 61. The shape of the slide rod 62 is a cylinder with a T-shaped cross-section. The shape of the slide groove 61 and the shape of the slide rod 62 are set to ensure that the slide rod 62 will not separate from the inside of the slide groove 61. The end of the slide rod 62 close to the conveyor belt 5 is fixedly connected to a connecting block 63, and the upper end of the connecting block 63 away from the slide rod 62 is fixedly connected to the outer wall of the conveyor belt 5, and the connecting block 63 is fixed to the conveyor belt 5 by bolts.
[0037] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7, a moving component 7 is arranged outside the connecting block 63. The moving component 7 includes mounting bars 71. The mounting bars 71 are arranged in two groups. One group of mounting bars 71 is fixedly connected to the inner wall of the front end of the bracket 2, and the other group of mounting bars 71 is fixedly connected to the inner wall of the rear end of the bracket 2. The distance between each group of mounting bars 71 is the same as the length in the left-right direction of the marking area. The length of the mounting bars 71 is the same as the length of the smaller-diameter area of the runner 4. The outer wall of the mounting bars 71 is fixedly connected to the end of the connecting block 63 away from the bracket 2. An installation groove 72 is formed in the inner wall of the mounting bars 71. The shape of the installation groove 72 is T-shaped. A control block 73 is slidably connected to the inner wall of the installation groove 72. The control block 73 is shaped like a cuboid connected to a triangular prism with a right-angled triangle cross-section. And the bottom end of the control block 73 on the side close to the middle of the installation groove 72 is set as a cut surface. The outer wall of the control block 73 is elastically connected to the inner wall of the installation groove 72 through a spring 74. One end of the spring 74 is fixedly connected to the outer wall of the control block 73, and the other end of the spring 74 is fixedly connected to the inner wall of the installation groove 72.
[0038] Refer to Figure 5 - Figure 7 , a push block 75 is slidably connected to the inner wall of the installation groove 72. The push block 75 is shaped like a cuboid with cut corners on the left and right sides of the top end, and the cut corners are shaped to fit the control block 73. A right-angled triangle cut corner is formed at the right bottom end of the push block 75. A control board 76 is fixedly connected to the inner wall of the bracket 2. The cross-section of the control board 76 is convex. A baffle 8 is fixedly connected to the top end of the bracket 2 outside the conveyor belt 5. The number of the baffles 8 is set to two, and the distance between the two baffles 8 is the same as the length in the front-rear direction of the marking area. Through the setting of the baffle 8, it is ensured that the object to be marked will not leave the marking area.
[0039] Working principle: When in use, the staff randomly places the object to be marked at the position between the two baffles 8 at the left end of the conveyor belt 5 and starts the motor 3, so that the output shaft of the motor 3 drives the runner 4 to rotate, and thus the conveyor belt 5 moves driven by the runner 4.
[0040] During the movement, when the object to be marked moves to the marking area, at this time, the conveyor belt 5 just drives the push block 75 on the left side of the marking area to contact the control board 76. During the contact process, the inclined surface at the bottom right end of the push block 75 first contacts the control board 76, so that the push block 75 generates an upward moving force under the control of the inclined surface and moves upward. When the push block 75 moves upward, the object at the edge of the marking area is just lifted by the top end of the push block 75. Since the top end of the push block 75 is a tip, after the object is lifted, it will move left or right along the inclined surfaces at the left and right ends of the push block 75, so as to completely move into the marking area or completely move to the left side position of the marking area, achieving the effect of preventing the object from being marked twice.
[0041] Meanwhile, during the conveyance of the conveyor belt 5, the conveyor belt 5 drives the connecting block 63 to move, thereby causing the connecting block 63 to drive the sliding rod 62 to move. Since the sliding rod 62 is always inside the sliding groove 61, the distance between the sliding rod 62 and the connecting block 63 and the conveyor belt 5 will not change during the movement, so as to achieve the effect of fixing the position of the conveyor belt 5 in the vertical direction, and prevent the middle of the conveyor belt 5 from bulging due to the far distance from the runner 4, resulting in the tilting of the object to be marked and affecting the marking effect.
[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
