[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0020] like Figure 1 As shown, in order to achieve the above-mentioned purpose, the present invention provides a laser processing device, comprising: A laser body, used to generate laser light to process the workpiece; A connecting member 10, a first end of which is connected to the handle portion of the laser body, and a second end of which extends toward the light-emitting portion of the laser body; and At least one guide wheel is connected to the second end of the connecting member 10 and can roll on the surface of the workpiece to be processed to drive the laser body to move on the surface of the workpiece to be processed, so that the laser generated by the laser body can stably act on the surface of the workpiece to be processed.

[0021] Specifically, in the laser processing equipment provided by the present invention, the laser body can adopt a solid laser or a gas laser with a certain power output to emit a laser beam. The laser body is connected to the first end of the connector 10 through its handle, and the second end of the connector 10 extends toward the light-emitting part of the laser body. The connector 10 can be made of metal or high-strength plastic to ensure the stability and durability of the connection. The guide wheel is fixed to the second end of the connector 10. The guide wheel can be a high-precision rolling bearing structure made of wear-resistant materials (such as cemented carbide or ceramics) to improve its durability and processing accuracy. The structural design of the guide wheel can ensure that it rolls smoothly on the surface of the workpiece to be processed, thereby guiding the laser body to move evenly on the surface of the workpiece to be processed and ensuring the stability of the laser beam.

[0022] In specific applications, the laser emitted by the laser body is guided by the guide wheel and always acts stably on the surface of the workpiece to be processed, ensuring the uniformity of the position, intensity and action area of ​​the laser beam during the laser processing process. On the surface of the workpiece to be processed, the laser body moves with the guide wheel during the rolling process, which can effectively prevent the laser beam from deviating and avoid the problem of laser beam instability in traditional laser processing. In addition, the setting of the guide wheel can also reduce the operator's operating burden, making the laser body easier to control during the processing process, thereby improving processing efficiency and accuracy.

[0023] By adopting the above technical solution, by introducing the cooperation of the guide wheel between the laser body and the workpiece to be processed, the laser beam can act stably on the surface of the workpiece to be processed, avoiding the deviation or uneven distribution of the laser beam, and ensuring the quality and efficiency of the processing. The design of the guide wheel makes the movement of the laser body more stable and controllable, reduces the error of manual operation, improves the processing accuracy, and thus improves the processing efficiency.

[0024] In one embodiment of the present application, a U-shaped bracket 20 is further provided at the second end of the connecting member 10, and a bending portion of the U-shaped bracket 20 is connected to the second end of the connecting member 10; There are two guide wheels, namely a first guide wheel 31 and a second guide wheel 32 . The first guide wheel 31 is rotatably connected to the first free end of the U-shaped bracket 20 , and the second guide wheel 32 is rotatably connected to the second free end of the U-shaped bracket 20 .

[0025] Specifically, a U-shaped bracket 20 is further provided at the second end of the connector 10, and the bending part of the U-shaped bracket 20 is connected to the second end of the connector 10. The U-shaped bracket 20 is made of metal material or high-strength plastic, and the bending part is firmly connected to the second end of the connector 10 to form a stable support structure. The design of the U-shaped bracket 20 can effectively support and fix the guide wheel to ensure that the guide wheel can rotate stably during the processing and avoid unnecessary displacement or vibration. The two ends of the U-shaped bracket 20 are respectively a first free end and a second free end, and the first guide wheel 31 and the second guide wheel 32 are rotatably connected to the two free ends of the U-shaped bracket 20. The first guide wheel 31 and the second guide wheel 32 both adopt a high-precision bearing structure to ensure their stability and accuracy when rolling on the surface of the workpiece to be processed.

[0026] In actual operation, the first guide wheel 31 and the second guide wheel 32 are respectively connected to the two free ends of the U-shaped bracket 20 by means of rotational connection. When the laser body is connected to the U-shaped bracket 20 through the connector 10, the guide wheels will roll on the surface of the workpiece to be processed as the laser body moves. The design of the guide wheels enables the laser body to stably and smoothly move on the surface of the workpiece to be processed, thereby ensuring that the laser beam always acts on the surface of the workpiece to be processed at the correct angle and position, avoiding the phenomenon of laser beam deviation or uneven distribution.

[0027] With the above technical solution, through the structural design of the U-shaped bracket 20, the second end of the connecting member 10 can support the guide wheel more stably, and through the synergistic effect of the first guide wheel 31 and the second guide wheel 32, the laser body can move smoothly on the surface of the workpiece to be processed. The two guide wheels are respectively located at the two ends of the U-shaped bracket 20, which can share the weight of the laser body and effectively control its movement trajectory, thereby further improving the processing accuracy and stability.

[0028] In one embodiment of the present application, a first hinge 33 is provided between the first guide wheel 31 and the first free end of the U-shaped bracket 20, the first free end of the U-shaped bracket 20 is connected to the first movable side of the first hinge 33, the first guide wheel 31 is connected to the second movable side of the first hinge 33, and the first guide wheel 31 can deflect along the first hinge 33 to a side away from the second guide wheel 32; The first guide wheel 31 is rotatably connected to a first damping cylinder 40 , and a free end of the first damping cylinder 40 is rotatably connected to the connecting member 10 .

[0029] Specifically, a first hinge 33 is provided between the first guide wheel 31 and the first free end of the U-shaped bracket 20. The first movable side of the first hinge 33 is connected to the first free end of the U-shaped bracket 20, and the second movable side is connected to the first guide wheel 31. By providing the first hinge 33, the first guide wheel 31 can rotate freely around the hinge axis, and can deflect along the first hinge 33 to the side away from the second guide wheel 32 when necessary. This deflection mechanism can effectively adjust the contact angle and pressure between the laser body and the surface of the workpiece to be processed, so that during the processing, the stability of the laser body and the contact effect of the guide wheel are optimized. The deflection design of the first guide wheel 31 is particularly suitable for processing the surfaces of workpieces to be processed with different shapes or different angles, and can ensure that the laser body moves smoothly on the surface of complex workpieces.

[0030] The first damping cylinder 40 is rotatably connected to the first guide wheel 31, and the free end of the first damping cylinder 40 is rotatably connected to the connecting member 10. The first damping cylinder 40 can provide additional stability to prevent the guide wheel from excessively deflecting or vibrating during the processing. The damping cylinder can also automatically adjust the pressure according to the changes in the working environment to adapt to different processing requirements, thereby ensuring that the laser body always remains stable during the entire processing process.

[0031] By adopting the above technical solution, the first guide wheel 31 can flexibly adapt to different processing requirements through the deflection function of the first hinge 33, especially when the surface shape of the workpiece to be processed is complex or inclined, the contact angle and pressure between the laser body and the workpiece to be processed can be effectively adjusted. In addition, the provision of the first damping cylinder 40 further improves the stability of the guide wheel and reduces the adverse effects caused by external force or equipment vibration, so that the laser body can move more smoothly during the processing process and maintain stable irradiation of the laser beam.

[0032] In one embodiment of the present application, a second hinge 34 is provided between the second guide wheel 32 and the second free end of the U-shaped bracket 20, the second free end of the U-shaped bracket 20 is connected to the first movable side of the second hinge 34, the second guide wheel 32 is connected to the second movable side of the second hinge 34, and the second guide wheel 32 can deflect along the second hinge 34 to a side away from the first guide wheel 31; The second guide wheel 32 is rotatably connected to a second damping cylinder, and a free end of the second damping cylinder is rotatably connected to the connecting member 10 .

[0033] Specifically, a second hinge 34 is provided between the second guide wheel 32 and the second free end of the U-shaped bracket 20. The first movable side of the second hinge 34 is connected to the second free end of the U-shaped bracket 20, and the second movable side is connected to the second guide wheel 32. By providing the second hinge 34, the second guide wheel 32 can rotate freely around the hinge axis, and can deflect along the second hinge 34 to the side away from the first guide wheel 31 when necessary. The deflection function of the second guide wheel 32 is similar to the deflection function of the first guide wheel 31. During the processing, it can be adaptively adjusted according to the specific shape and angle of the surface of the workpiece to be processed. Through the coordinated deflection of the first guide wheel 31 and the second guide wheel 32, the laser body can more flexibly follow the surface of the workpiece to be processed, ensuring that the laser beam acts on the surface of the workpiece to be processed stably and evenly, especially under complex surfaces or variable processing angles, which can effectively improve the processing quality.

[0034] The second guide wheel 32 is rotatably connected to a second damping cylinder, and the free end of the second damping cylinder is rotatably connected to the connecting member 10. The second damping cylinder has the same function as the first damping cylinder 40, providing additional damping to control the rotation speed and stability of the second guide wheel 32.

[0035] By adopting the above technical solution, through the combination of the second guide wheel 32 and the second hinge 34, the second guide wheel 32 can flexibly adapt to the changes in the surface shape of the workpiece to be processed, ensuring that the laser body maintains a stable laser beam action at different angles. The setting of the second damping cylinder further improves the control accuracy and stability of the second guide wheel 32, and prevents processing instability or laser beam deviation caused by external vibration or rapid rotation. The coordinated deflection design of the first guide wheel 31 and the second guide wheel 32 not only improves the flexibility and stability during the processing, but also effectively avoids the processing error caused by the guide wheel offset.

[0036] In one embodiment of the present application, a shock absorbing spring is sleeved on the first damping cylinder 40 and / or the second damping cylinder.

[0037] Specifically, a shock absorbing spring is sleeved on the first damping cylinder 40 and / or the second damping cylinder. The combination of the shock absorbing spring and the damping cylinder can further improve the system's buffering effect on vibration during laser processing, and reduce the impact of external shocks or equipment vibrations on the motion trajectory of the guide wheel and the laser body. The design of the shock absorbing spring complements the damping cylinder. During the movement of the guide wheel, the spring can absorb a certain amount of impact energy and release it slowly, avoiding excessive impact that causes unstable rotation of the guide wheel or reduced processing accuracy. The preload force and elastic constant of the shock absorbing spring can be selected according to actual needs to meet the shock absorption requirements under different working conditions.

[0038] When the laser processing equipment is performing laser beam processing, the damping cylinder and the shock absorbing spring work together to slow down the impact rate of the guide wheel through air pressure and spring elasticity, making the rotation of the guide wheel more stable and uniform. During the processing, if the equipment vibrates slightly or has irregular impacts, the shock absorbing spring can absorb part of the impact energy first, and through the synergistic effect with the cylinder, prevent these vibrations from being transmitted to the laser body and the surface of the workpiece to be processed, thereby reducing processing errors and improving processing stability.

[0039] By adopting the above technical solution, the combination of the shock-absorbing spring and the damping cylinder can more effectively reduce the unstable factors caused by vibration or impact, making the movement of the guide wheel smoother, avoiding the instability and deviation of the laser beam during the processing, and ensuring that the laser body moves evenly and stably on the surface of the workpiece to be processed.

[0040] In one embodiment of the present application, a rotating member 50 is provided between the laser body and the connecting member 10; The first end of the rotating member 50 is connected to the handle portion of the laser body, and the second end of the rotating member 50 is rotatably connected to the first end of the connecting member 10 .

[0041] Specifically, a rotating member 50 is provided between the laser body and the connecting member 10. The first end of the rotating member 50 is connected to the handle portion of the laser body, and the second end is rotatably connected to the first end of the connecting member 10. The setting of the rotating member 50 allows the laser body to rotate at a certain angle relative to the connecting member 10, so that the laser body can flexibly adjust its angle and position relative to the workpiece to be processed during the processing. The rotating member 50 can use a bearing or other suitable connection structure to ensure the stability and smoothness of its rotation.

[0042] By adopting the above technical solution, through the setting of the rotating part 50, the rotating connection between the laser body and the connecting part 10 enables the laser body to flexibly adjust its angle relative to the workpiece to be processed during the processing process, ensuring that the laser beam always acts stably on the surface of the workpiece to be processed, avoiding uneven processing or errors caused by improper laser position or angle.

[0043] In one embodiment of the present application, an adjusting member is further provided between the laser body and the rotating member 50; The first end of the adjusting member is connected to the handle portion of the laser body, and the second end of the adjusting member is connected to the rotating member 50. The laser body can reciprocate along the length direction of the adjusting member to change the position of the laser body; wherein the length direction of the adjusting member is perpendicular to the length direction of the rotating member 50.

[0044] Specifically, an adjusting member is further provided between the laser body and the rotating member 50. The first end of the adjusting member is connected to the handle portion of the laser body, and the second end is connected to the rotating member 50. The adjusting member is used to enable the laser body to reciprocate along the length direction of the adjusting member, thereby changing the position of the laser body, and further adjusting the working distance and processing accuracy of the laser. The length direction of the adjusting member is perpendicular to the length direction of the rotating member 50, ensuring that the laser body is not affected by the movement of the rotating member 50 when adjusting its position, and can independently move back and forth accurately in the vertical direction.

[0045] In specific applications, the adjustment member can be implemented by a threaded structure, a sliding track or a pneumatic device. For example, the adjustment member can be designed as an adjustment rod with a thread. By rotating the adjustment member, the laser body can be accurately moved forward or backward to adjust the distance between the laser body and the workpiece to be processed. Since the length direction of the adjustment member is perpendicular to the length direction of the rotating member 50, when the laser body is adjusted in position, it can not only flexibly change the angle (through the action of the rotating member 50), but also accurately adjust the longitudinal position of the laser body to meet different processing requirements.

[0046] By adopting the above technical solution, the laser body can be accurately adjusted in front and back positions without affecting the rotation angle by setting the adjustment member. Through this position adjustment, the laser body can better adapt to the workpieces of different shapes and sizes to be processed, ensuring that the laser beam always acts on the surface of the workpiece at the best position.

[0047] In one embodiment of the present application, the adjusting member is a screw 60, the rotating member 50 is provided with a threaded through hole for the screw 60 to pass through, and the screw 60 is provided with a locking nut 61 that can lock the screw 60 on the rotating member 50; the handle portion of the laser body is provided with a through hole connected to the screw 60, and the screw 60 is provided with at least one limit nut 62 for limiting the movement of the laser body after the laser body moves to a specified position.

[0048] Specifically, the adjusting member is a screw 60, which is driven through a threaded through hole on the rotating member 50. The rotation of the screw 60 enables the laser body to reciprocate along the axial direction of the screw 60 through the cooperation of the thread and the rotating member 50, thereby realizing precise adjustment of the position of the laser body. A locking nut 61 is provided on the screw 60, and the locking nut 61 is used to lock the screw 60 on the rotating member 50 to prevent unnecessary displacement or loosening of the position of the screw 60 during the adjustment process, and ensure that the laser body can maintain a stable positioning after adjustment.

[0049] The handle of the laser body is provided with a through hole connected to the screw 60, which allows the screw 60 to pass smoothly and connect to the laser body. When the laser body is adjusted in position by rotating the screw 60, it can move back and forth accurately and change the distance between the laser body and the workpiece to be processed as needed. This design ensures that the laser body can move smoothly during the adjustment process, and the position of the laser body can be accurately controlled by rotating the screw 60.

[0050] In addition, at least one limit nut 62 is provided on the screw 60 to limit the further movement of the laser body after it moves to the specified position. The function of the limit nut 62 is to prevent the laser body from moving unnecessarily due to over-adjustment, and to ensure that the laser body is stably fixed at the specified position. By adjusting the rotation of the screw 60, the limit nut 62 can be accurately set at the desired position. Once the laser body moves to this position, the limit nut 62 will prevent it from moving further, thereby ensuring that the laser body always remains in the best working position.

[0051] By adopting the above technical solution, the design of the screw 60, the locking nut 61 and the limit nut 62 can ensure the stable position of the laser body during the adjustment process, avoiding errors caused by looseness or over-adjustment.

[0052] In one embodiment of the present application, a rotating nut 70 is provided on the screw rod 60, and the rotating nut 70 is arranged on one side of the limiting nut 62. A support member 80 is provided on the rotating nut 70, and the handle portion of the laser body is connected to the support member 80 by screws.

[0053] Specifically, the screw rod 60 is provided with a rotating nut 70, and the rotating nut 70 is located on one side of the limit nut 62. The rotating nut 70 cooperates with the thread of the screw rod 60, and the movement of the laser body can be adjusted by rotating the rotating nut 70. The setting of the rotating nut 70 enables the laser body to accurately adjust its position during the adjustment process, thereby changing the position of the laser body. The rotating nut 70 is provided with a support member 80, and the support member 80 plays a supporting and fixing role between the rotating nut 70 and the laser body. The support member 80 is connected to the handle part of the laser body by a screw to ensure that the rotating nut 70 and the laser body are closely connected, and to provide stable support when the rotating nut 70 rotates. The design of the support member 80 enhances the stability of the laser body during the adjustment process, and avoids the influence of the accuracy of the position of the laser body due to shaking or uneven load generated during the adjustment process.

[0054] By adopting the above technical solution, the adjustment of the laser body is more stable and accurate through the cooperation of the rotating nut 70 and the supporting member 80.

[0055] In one embodiment of the present application, there are two limit nuts 62, which are respectively arranged on both sides of the handle of the laser body.

[0056] Specifically, there are two limit nuts 62, which are respectively arranged on both sides of the handle of the laser body. The function of each limit nut 62 is to limit the moving range of the laser body when the laser body moves along the screw 60, ensuring that the laser body does not exceed the predetermined working range. The two limit nuts 62 are respectively arranged on both sides of the handle of the laser body to ensure that the laser body can be evenly limited in two directions during the adjustment process, realize bidirectional restriction, and ensure that the laser body does not have unnecessary displacement during operation.

[0057] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
