Description

Technical Field

[0001] The utility model relates to the technical field of paint stripping, in particular to an automatic laser paint stripping device. Background Art

[0002] Laser paint stripping is a common process for removing paint from material surfaces.

[0003] During the laser paint stripping process, the light beam emitted by the laser generator is absorbed by the paint layer on the surface of the material, forming a rapidly expanding plasma and generating a shock wave, which can break the paint layer into fragments and remove them, thereby completing automatic paint stripping.

[0004] A guide block will be installed on the workbench of the paint stripping device. Before paint stripping, the material needs to be pressed against the guide block so that the material is located at the corresponding position for paint stripping. Therefore, when paint stripping materials of different sizes, the position of the guide block needs to be adjusted. Most of the current guide blocks are fixed by bolts, which results in the need to use a working tool to tighten the bolts when adjusting the position of the guide block, thereby reducing the convenience of adjusting the guide block. For this reason, we propose an automatic laser paint stripping device that is easy to adjust the guide block. Utility Model Content

DETAILED DESCRIPTION

[0021] 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.

[0022] The utility model provides Figure 1-3 An automatic laser paint stripping device is shown, including a workbench 101 and a positioning mechanism. A laser assembly is arranged above the workbench 101, and the laser assembly includes a top plate 104 fixedly arranged above the workbench 101. A laser emitter 105 is installed at the bottom end of the top plate 104. A placement table 102 is fixedly arranged at the top of the workbench 101, and a guide block 103 is arranged at the top of the placement table 102. The material is placed on the top of the placement table 102 and against the guide block 103, and then the laser emitter 105 works to emit a light beam. The paint layer on the surface of the material absorbs the light beam to form a rapidly expanding plasma and generate a shock wave. The shock wave causes the paint layer to become fragments and be removed, thereby achieving the purpose of automatic paint stripping.

[0023] In a preferred embodiment, the positioning mechanism is arranged between the guide block 103 and the placement table 102, and the positioning mechanism includes a fixed shaft 201 fixedly inserted and connected to the bottom end of the guide block 103, and a socket 202 is provided at the top of the placement table 102. The outer wall of the fixed shaft 201 is movably inserted and connected with the inner wall of the socket 202, and a plurality of positioning shafts 204 are inserted and arranged on the outer wall of the fixed shaft 201, and a positioning groove 203 is provided on the inner wall of the socket 202. The positioning shaft 204 is inserted and arranged inside the positioning groove 203. According to different paint stripping positions, the position of the guide block 103 needs to be adjusted. During the adjustment process, pick up the guide block 103, insert the fixed shaft 201 at the bottom end of the guide block 103 into the corresponding socket 202, and then insert the plurality of positioning shafts 204 into the positioning groove 203 to complete the positioning of the guide block 103. When the positioning needs to be released, it is only necessary to separate the positioning shaft 204 from the positioning groove 203. The whole process does not require the aid of other tools, thereby making the adjustment of the guide block 103 more convenient.

[0024] Among them, a movable hole 301 is opened at the top of the fixed shaft 201, and a movable rod 303 is movably connected to the inner wall of the movable hole 301; a plurality of connecting holes 302 are opened on the outer wall of the fixed shaft 201, and the plurality of connecting holes 302 are connected with the inside of the movable hole 301; the outer wall of the positioning shaft 204 is movably connected to the inner wall of the connecting hole 302; a pull ring 304 is fixedly connected to the top of the movable rod 303; when the positioning shaft 204 is inserted into the positioning groove 203, the movable rod 303 is moved downward to limit the positioning shaft 204; as long as the movable rod 303 does not move up, the positioning shaft 204 can be stably inserted in the positioning groove 203, thereby improving the stability of the positioning mechanism.

[0025] Among them, a hemispherical surface 401 is formed at one end of the positioning shaft 204 close to the movable rod 303, and an annular groove 402 is formed on the outer wall of the movable rod 303. Through the cooperation between the hemispherical surface 401 and the annular groove 402, one end of the hemispherical surface 401 of the positioning shaft 204 can fit into the annular groove 402, further improving the positioning stability of the positioning shaft 204.

[0026] Among them, the inner wall of the movable hole 301 is provided with a first movable groove 501, and the inner wall of the first movable groove 501 is slidably connected with a first limit plate 502, and the first limit plate 502 is fixedly sleeved on the outer wall of the movable rod 303. The top of the first limit plate 502 is provided with a first spring 503, and the first spring 503 is sleeved on the outer wall of the movable rod 303. Through the elastic action of the first spring 503, the first limit plate 502 is always squeezed by the first spring 503, so that the movable rod 303 always has a tendency to move downward, so that the movable rod 303 can be stably positioned on the positioning shaft 204 when the movable rod 303 is not subjected to a large upward external force, thereby further providing the stability of the positioning mechanism.

[0027] Among them, the inner wall of the connecting hole 302 is provided with a second movable groove 601, and the inner wall of the second movable groove 601 is slidably connected with a second limiting plate 602, and the second limiting plate 602 is fixedly sleeved on the outer wall of the positioning shaft 204. The second limiting plate 602 is provided with a second spring 603 on the side away from the movable rod 303, and the second spring 603 is sleeved on the outer wall of the positioning shaft 204. When the positioning of the positioning mechanism needs to be released, the pull ring 304 is pulled up to make the movable rod 303 move up until the movable rod 303 no longer limits the positioning shaft 204. At this time, under the elastic action of the second spring 603, the second limiting plate 602 drives the positioning shaft 204 to move, so that the positioning shaft 204 is completely retracted into the connecting hole 302, so that the positioning groove 203 no longer limits the positioning shaft 204, and the fixed shaft 201 can be moved upward to adjust the position of the guide block 103, which further improves the convenience of adjusting the guide block 103.

[0028] Among them, the bottom end of the movable rod 303 is fixedly connected with an extrusion block 701, and the extrusion block 701 is set in an inverted cone shape. When the movable rod 303 moves downward, the inclined outer wall of the extrusion block 701 will first contact the hemispherical surface 401, so that the outer wall of the extrusion block 701 is squeezed with the hemispherical surface 401, and the positioning shaft 204 can be moved into the positioning groove 203, thereby improving the convenience of using the movable rod 303.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
