Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, specifically a protective focusing mechanism for a laser marking machine. Background Technology

[0002] Laser marking technology has been widely used due to its advantages such as high precision, permanent marking, and non-contact processing. With the increasing demand for product marking across various industries, performance optimization of laser marking machines has become a key issue.

[0003] Disassembling focusing equipment using existing technology often requires specialized tools, such as screwdrivers, wrenches, and disassembly jigs of specific sizes. Some miniaturized, high-precision focusing equipment also requires micro-tools and professional electronic repair tools. Ordinary users or non-professional repair personnel usually do not have these tools, making it difficult to perform disassembly operations. Utility Model Content

[0004] The purpose of this invention is to provide a protective focusing mechanism for a laser marking machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective focusing mechanism for a laser marking machine, comprising:

[0006] Base;

[0007] A transmission assembly is placed inside a base. The transmission assembly includes a guide rail fixedly connected to the base, a clamping rod slidably connected inside the guide rail, a clamping frame slidably connected to the clamping rod, a second connecting rod fixedly connected to the clamping frame, a transmission plate fixedly connected to the second connecting rod, a first connecting rod fixedly connected to the transmission plate, a lower pressure plate fixedly connected to the first connecting rod, a transmission rod rotatably connected to the lower pressure plate, a clamping plate slidably connected to the bottom of the transmission rod, and a fixed frame slidably connected to the transmission plate.

[0008] A transmission frame is fixedly connected to a base. A fixing rod is fixedly connected inside the transmission frame. A connecting plate is fixedly connected to the fixing rod. A fixing rod is fixedly connected to the connecting plate. The fixing rod is fixedly connected to the fixing frame.

[0009] Furthermore, there are two clamping rods, and a damping spring is fixedly connected between the two clamping rods.

[0010] The above technical solution involves setting two clamping rods. When in use, a damping spring is fixed between the two clamping rods. The clamping rods are stretched towards the middle by external force, and then fixed by the clamping frame.

[0011] Furthermore, the first connecting rod is slidably connected to the fixed frame.

[0012] The above technical solution is adopted as follows: by setting the first connecting rod to slide in a fixed frame, when in use, pressing down the first connecting rod squeezes the transmission rod, causing the two clamping plates to clamp inward and lock the focuser in place. After the lower pressure plate presses against the focuser, bolts are used to fix the lower pressure plate to the fixed frame to limit its position.

[0013] Furthermore, both the transmission plate and the clamping plate have openings.

[0014] The above technical solution is adopted: by opening holes in the transmission and clamping plates, it is convenient to lock the focuser in place during use.

[0015] Furthermore, the transmission rod is rotatably connected to the lower pressure plate via a rotating shaft, and a universal joint is fixedly connected between the transmission rod and the clamping plate.

[0016] Using the above technical solution: when the pressure plate is pressed down, it will drive the transmission rod to move inward to clamp the focuser, and the transmission rod can easily drive the clamping plate.

[0017] Furthermore, threaded holes are provided on both the transmission frame and the connecting plate.

[0018] The above technical solution is adopted: by opening threaded holes in the transmission frame and the connecting plate, it is convenient to limit the position of the connecting plate and realize the position limit of the clamping frame.

[0019] Furthermore, threaded holes are provided on both the lower pressure plate and the fixing frame.

[0020] The above technical solution is adopted: by setting threaded holes on the lower pressure plate and the fixing frame, it is convenient to limit the lower pressure plate during use.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the lower pressure plate is rotatably connected to the transmission rod via a rotating shaft. During the pressing process, the transmission rod moves. Since a universal joint is fixedly connected between the bottom of the transmission rod and the clamping plate, the pressing of the lower pressure plate causes the first connecting rod to press down synchronously. The first connecting rod is slidably connected to the fixed frame. When pressing down, it squeezes the transmission rod, causing the clamping plate to move inward and clamp the focuser steadily from both sides, ensuring that the focuser is reliably fixed. Then, the lower pressure plate is fixed to the fixed frame with bolts to complete the installation of the focuser. This solves the problem in the prior art where it is difficult to replace the focuser when it needs to be replaced. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example:

[0033] like Figures 1-4 As shown, this utility model provides a technical solution: a protective focusing mechanism for a laser marking machine, comprising:

[0034] Base 1;

[0035] Transmission component 2 is placed inside base 1. Transmission component 2 includes a guide rail 29 fixedly connected to base 1. A clamping rod 211 is slidably connected inside the guide rail 29. A clamping frame 28 is slidably connected to the clamping rod 211. A second connecting rod 27 is fixedly connected to the clamping frame 28. A transmission plate 22 is fixedly connected to the second connecting rod 27. A first connecting rod 26 is fixedly connected to the transmission plate 22. A lower pressure plate 23 is fixedly connected to the first connecting rod 26. A transmission rod 24 is rotatably connected to the lower pressure plate 23. A clamping plate 25 is slidably connected to the bottom of the transmission rod 24. A fixed frame 21 is slidably connected to the transmission plate 22.

[0036] The transmission frame 3 is fixedly connected to the base 1. A fixing rod 32 is fixedly connected inside the transmission frame 3. A connecting plate 31 is fixedly connected to the fixing rod 32. The fixing rod 32 is fixedly connected to the connecting plate 31. The fixing rod 32 is fixedly connected to the fixing frame 21.

[0037] In this invention, the lower pressure plate 23 is rotatably connected to the transmission rod 24 via a rotating shaft. During the pressing process, the transmission rod 24 is driven to move. Since a universal joint is fixedly connected between the bottom of the transmission rod 24 and the clamping plate 25, the pressing of the lower pressure plate 23 will cause the first connecting rod 26 to press down synchronously. The first connecting rod 26 is slidably connected to the fixed frame 21. When pressing down, it squeezes the transmission rod 24, causing the clamping plate 25 to move inward and clamp the focuser steadily from both sides, ensuring that the focuser is reliably fixed. Then, the lower pressure plate 23 is fixed to the fixed frame 21 with bolts to complete the installation of the focuser. This solves the problem in the prior art where it is difficult to replace the focuser when it needs to be replaced.

[0038] There are two clamping rods 211, and a damping spring 210 is fixedly connected between the two clamping rods 211. By setting two clamping rods 211, the damping spring 210 is fixed between the two clamping rods 211 during use. The clamping rods 211 are stretched towards the middle by external force, and then fixed by the clamping frame 28.

[0039] The first connecting rod 26 is slidably connected to the fixed frame 21. By setting the first connecting rod 26 to the fixed frame 21 in a slidable connection, when in use, pressing down the first connecting rod 26 squeezes the transmission rod 24, causing the two clamping plates 25 to clamp inward and lock the focuser in place. After the lowering plate 23 presses against the focuser, bolts are used to fix the lowering plate 23 to the fixed frame 21 to limit its position.

[0040] Both the transmission plate 22 and the clamping plate 25 have openings, which make it easy to lock the focuser in place during use.

[0041] The transmission rod 24 is rotatably connected to the lower pressure plate 23 via a rotating shaft. A universal joint is fixedly connected between the transmission rod 24 and the clamping plate 25. When the lower pressure plate 23 is pressed down, it will drive the transmission rod 24 to move inward to clamp the focuser. The transmission rod 24 facilitates the transmission of the clamping plate 25.

[0042] Both the transmission frame 3 and the connecting plate 31 are provided with threaded holes. By providing threaded holes on the transmission frame 3 and the connecting plate 31, it is convenient to limit the position of the connecting plate 31 and realize the position limit of the clamping frame 28.

[0043] Both the lower pressure plate 23 and the fixing frame 21 are provided with threaded holes. By providing threaded holes on the lower pressure plate 23 and the fixing frame 21, it is convenient to limit the lower pressure plate 23 during use.

[0044] Working principle: such as Figures 1-4 As shown;

[0045] In use, the clamping rod 211 is moved to press the workpiece, placing the focuser (model: Keyence LV-H32 laser sensor head) on the opening on the lower pressure plate 23 and through the opening on the transmission plate 22. At this time, the lower pressure plate 23 is pressed down, causing the lower pressure plate 23 to press down the transmission rod 24. The clamping plate 25 is moved inward to clamp the focuser. At this time, the lower pressure plate 23 abuts against the focuser. Then, the lower pressure plate 23 is fixed to the fixing frame 21 with bolts and connected to the focuser.

[0046] During this process, when the first connecting rod 26 is pressed down, it will drive the transmission plate 22 to press down, causing the second connecting rod 27 to press down the clamping frame 28. The clamping frame 28 will lock the two clamping rods 211, thereby limiting the clamping rods 211.

[0047] The operator applies external force to press down on the connecting plate 31, causing the connecting plate 31 to drive the fixing rod 32 to press down on the fixing frame 21. The fixing frame 21 then drives the second connecting rod 27 to press down, which in turn drives the clamping frame 28 to press down further. This ensures that the clamping frame 28 tightly presses against the clamping rod 211. The transmission frame 3 is then fixed to the connecting plate 31 with bolts, limiting the position of the connecting plate 31 and further limiting the position of the second connecting rod 27. This prevents the focuser from falling off and the processed parts from being loosely fixed, thus avoiding damage to the focuser.

[0048] After that, the focuser is activated, and the sensor will start to detect the distance between the laser head and the workpiece surface. It will then automatically adjust the Z-axis position of the laser head according to the preset algorithm until the optimal focus is achieved. The operator can check whether the autofocus is successful by observing the indicator lights on the focuser.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
