Specific embodiments
[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figure 1-2 , the present utility model provides a technical solution: a laser head deflection device, including a support frame 1, on which a first deflection mechanism 2, a second deflection mechanism 3 connected to the first deflection mechanism 2, and a laser head 4 connected to the second deflection mechanism 3 are respectively provided. The first deflection mechanism 2 can deflect to drive the second deflection mechanism 3 to deflect simultaneously, and further drive the laser head 4 located on the second deflection mechanism 3 to deflect. At the same time, the second deflection mechanism 3 can also deflect independently to drive the laser head 4 to deflect. The deflection angles of the first deflection mechanism 2 and the second deflection mechanism 3 are intersectingly arranged, so as to meet the deflection requirements of the laser head 4 in various different directions.
[0021] On one side of the first deflection mechanism 2, there is a first elastic member 5 with one end connected thereto. The other end of the first elastic member 5 is connected to the support frame 1, and the connections between the first elastic member 5 and the first deflection mechanism 2 and the support frame 1 are rotational connections. On the other side of the first deflection mechanism 2, there is a second elastic member 6 with one end connected thereto. The other end of the second elastic member 6 is connected to the second deflection mechanism 3, and the connections between the second elastic member 6 and the first deflection mechanism 2 and the second deflection mechanism 3 are rotational connections. The first elastic member 5 and the second elastic member 6 are tension springs, or they can also be compression springs. The first deflection mechanism 2 includes a first deflection motor 20 fixedly installed on the support frame 1. The first deflection motor 20 is provided with a first rotating shaft in transmission connection therewith. The transmission mode between the first deflection motor 20 and the first rotating shaft is through a gear set. The first deflection mechanism 2 further includes a rotating frame 21 fixedly connected to one end of the first rotating shaft. The rotating frame 21 includes a connecting plate 210 and a support plate 211 fixedly connected to the connecting plate 210. The horizontal cross-section of the rotating frame 21 is L-shaped. On one side of the connecting plate 210, there is a first connecting member 212. The first elastic member 5 is rotationally connected to the first deflection mechanism 2 through a rotational connection with the first connecting member 212. The second deflection mechanism 3 is installed on the support plate 211. Therefore, when it is necessary to deflect the laser head 4 by using the first deflection mechanism 2, at this time, the first deflection motor 20 drives the first rotating shaft to rotate, thereby driving the rotating frame 21 to rotate. Since the second deflection mechanism 3 is installed on the support plate 211, when the rotating frame 21 rotates, the support plate 211 will also rotate, thereby driving the second deflection mechanism 3 to rotate simultaneously, and further driving the laser head 4 located on the second deflection mechanism 3 to rotate, so as to realize the deflection of the laser head 4 in the deflection direction of the first deflection mechanism 2. Since there is a first elastic member 5 with a rotational connection between the rotating frame 21 of the first deflection mechanism 2 and the support frame 1, when the rotating frame 21 deflects, at this time, the first elastic member 5 is in a stretched state. Since the rotating frame 21 is fixedly connected to the first rotating shaft, in addition to the deflection force of the first deflection motor 20, the first rotating shaft in the first deflection mechanism 2 also receives a pulling force from the first elastic member 5 in the direction opposite to the deflection force. Therefore, at this time, the pulling force of the first elastic member 5 will pull the first rotating shaft in the direction opposite to the deflection force, thereby eliminating and compensating for the gear installation gap between the first deflection motor 20 and the first rotating shaft, reducing the gear assembly error, and further correcting the deflection angle of the laser head 4, thereby greatly improving the deflection accuracy of the laser head 4 in the deflection direction of the first deflection mechanism 2.
[0022] The second deflection mechanism 3 includes a second deflection motor 30 fixedly mounted on the support plate 211, the second deflection motor 30 is provided with a second rotating shaft 31 which is transmission-connected thereto, the second deflection mechanism 3 also includes a rotating plate 32 fixedly connected to one end of the second rotating shaft 31, the laser head 4 is fixedly mounted between the rotating plate 32, the other end of the second rotating shaft 31 passes through the support plate 211, the other end of the second elastic member 6 is connected to the end of the second rotating shaft 31 passing through the support plate 211, the connecting plate 210 is provided with a second connecting member 213 on the side close to the support plate 211, the second rotating shaft 31 passes through the end of the support plate 211 and is provided with a third connecting member 310, the two ends of the second elastic member 6 are rotationally connected to the second connecting member 213 and the third connecting member 310 respectively, when the laser head 4 needs to deflect in the deflection direction of the second deflection mechanism 3, at this time, the second deflection motor 30 drives the second rotating shaft 31 to rotate, and the second deflection motor 30 and the second rotating shaft 31 are also transmission-connected through a gear set. , the second rotating shaft 31 drives the rotating plate 32 to rotate. Since the laser head 4 is fixedly mounted on the rotating plate 32, the rotating plate 32 will also drive the laser head 4 to deflect when it rotates. However, since a second elastic member 6 is rotatably connected to each other between the other end of the second rotating shaft 31 and the connecting plate 210, when the second deflection mechanism 3 deflects autonomously, the second elastic member 6 is stretched. Therefore, at this time, in addition to the deflection force from the second deflection motor 30, the second rotating shaft 31 is also subjected to the pulling force of the second elastic member 6. Therefore, the pulling force of the second elastic member 6 will pull the second rotating shaft 31 in the opposite direction of the deflection direction, thereby eliminating and compensating the gear installation gap between the second deflection motor 30 and the second rotating shaft 31, reducing the gear installation error between the second deflection motor 30 and the second rotating shaft 31, and then correcting the deflection angle of the laser head 4, thereby greatly improving the deflection accuracy of the laser head 4 along the deflection direction of the second deflection mechanism 3, and ensuring the product quality after the inclined cutting process.
[0023] Working principle of the utility model: By providing a first elastic member 5 that is rotatably connected between the first deflection mechanism 2 and the support frame 1, when the first deflection mechanism 2 deflects to drive the second deflection mechanism 3 to deflect, and further drives the laser head 4 located on the second deflection mechanism 3 to deflect, at this time, since there is a first elastic member 5 that is rotatably connected between the first deflection mechanism 2 and the support frame 1, as the first deflection mechanism 2 deflects, the first elastic member 5 is in a stretched state at this time. Therefore, in addition to the deflection force, the first deflection mechanism 2 is also subjected to a pulling force in the direction opposite to the deflection direction. So, the pulling force of the first elastic member 5 will drive the first deflection mechanism 2 to be pulled in the direction of the pulling force, thereby compensating and correcting the gear installation clearance in the first deflection mechanism 2, thus ensuring the deflection accuracy of the laser head 4. When the second deflection mechanism 3 deflects to drive the laser head 4 to deflect, the second elastic member 6 is in a stretched state. Therefore, in addition to the deflection force, the second deflection mechanism 3 is also subjected to a pulling force in the direction opposite to the deflection direction. So, the pulling force of the second elastic member 6 will drive the second deflection mechanism 3 to be pulled in the direction of the pulling force, thereby compensating and correcting the gear installation clearance in the second deflection mechanism 3, thus ensuring the deflection accuracy of the laser head 4. Therefore, by providing the first elastic member 5 and the second elastic member 6, the gear installation clearances in the first deflection mechanism 2 and the second deflection mechanism 3 can be compensated, thereby correcting the deflection angle of the laser head 4, thus greatly improving the deflection accuracy of the laser head 4 and ensuring the product accuracy during cutting and processing.
