Description

A detection focusing lens module for laser engraving machines Technical Field

[0001] This utility model relates to the field of focusing lens technology, and in particular to a detection focusing lens module for a laser engraving machine. Background Technology

[0002] Laser engraving machines use a laser head to emit high-intensity laser light, which causes the surface of the workpiece to be processed to be subjected to strong heat energy, resulting in a rapid increase in temperature. This causes the surface to melt or vaporize quickly due to the high temperature. Combined with the movement trajectory of the laser head, the processing purpose is achieved. Lenses need to be installed in the laser head to focus the light. Multiple lenses are set for focusing the light, from top to bottom: collimating lens, focusing lens, and protective lens.

[0003] Currently, focusing lenses have a very short lifespan, requiring replacement approximately every two to three months. However, in existing technologies, focusing lenses are fixedly mounted on a focusing lens mount, requiring the unscrewing of multiple fixing bolts before disassembling the focusing lens, which reduces the efficiency of focusing lens disassembly. Summary of the Invention

[0004] The purpose of this invention is to provide a detection focusing lens module for laser engraving machines, which aims to solve the problem that existing focusing lens modules are inconvenient to disassemble and replace.

[0005] To achieve the above objectives, this utility model provides a detection focusing lens module for a laser engraving machine, including a mounting base, a focusing lens body, an alarm device body, and a disassembly and assembly mechanism. The disassembly and assembly mechanism includes two sliding rods, two sliding cylinders, a mounting frame, a rotating disk, and a fixing plate. The mounting base has a fixing groove.

[0006] The two slide rods are fixedly connected to the mounting base and are both located inside the mounting base. The two slide cylinders are slidably connected to the two slide rods and are located around the two slide rods. The mounting frame is fixedly connected to the two slide cylinders and is located between the two slide cylinders. The rotating disk is rotatably connected to the mounting frame and is located on the mounting frame. The fixing plate is installed on one side of the rotating disk. The focusing lens body is installed on the mounting frame. The alarm device body is installed on one side of the mounting frame.

[0007] The fixing plate includes a connecting rod and a fixing rod. The connecting rod is fixedly connected to the rotating disk and is located on one side of the rotating disk. The fixing rod is fixedly connected to the connecting rod and is located on the connecting rod.

[0008] The disassembly and assembly mechanism further includes a locking block and a first spring. The locking block is slidably connected to the mounting frame and passes through the mounting frame. The first spring is fixedly connected to the locking block and the mounting frame, and is located between the mounting frame and the locking block.

[0009] The disassembly and assembly mechanism further includes a pull handle and an anti-slip sleeve. The pull handle is fixedly connected to the locking block and slidably connected to the mounting bracket, and passes through the mounting bracket. The anti-slip sleeve is fixedly connected to the pull handle and is located around the pull handle.

[0010] The disassembly and assembly mechanism further includes two second springs, which are respectively fixedly connected to the mounting base and to the two slide cylinders, and are located between the slide cylinders and the mounting base.

[0011] This utility model discloses a detection focusing lens module for a laser engraving machine. The mounting base provides installation conditions for the disassembly and assembly mechanism, the mounting bracket provides installation conditions for the focusing lens body and the alarm device body, and the two sliding rods provide installation conditions for the two sliding cylinders. The alarm device body can monitor the focusing lens body and issue an alarm when replacement is needed. When the focusing lens body needs to be disassembled, the rotating disk is rotated away from the fixing groove by the fixing plate until the fixing plate is completely away from the fixing groove. Then, the mounting bracket can be pulled, and the two sliding cylinders drive the mounting bracket to move away from the mounting base until the focusing lens body on the mounting bracket is completely removed from the mounting base, at which point the focusing lens body can be replaced. Conversely, the focusing lens body can be installed. This solves the problem of existing focusing lens modules being inconvenient to disassemble and replace. Attached Figure Description

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please refer to Figures 1-3. This utility model provides a detection focusing lens module for a laser engraving machine, including a mounting base 1, a focusing lens body 2, an alarm device body 3, and a disassembly and assembly mechanism. The disassembly and assembly mechanism includes two sliding rods 4, two sliding cylinders 5, a mounting bracket 6, a rotating disk 7, and a fixing plate. The mounting base 1 has a fixing groove 8.

[0019] The two slide rods 4 are fixedly connected to the mounting base 1 and are both located inside the mounting base 1. The two slide cylinders 5 are slidably connected to the two slide rods 4 and are located around the two slide rods 4 respectively. The mounting frame 6 is fixedly connected to the two slide cylinders 5 and is located between the two slide cylinders 5. The rotating disk 7 is rotatably connected to the mounting frame 6 and is located on the mounting frame 6. The fixing plate is installed on one side of the rotating disk 7. The focusing lens body 2 is installed on the mounting frame 6. The alarm device body 3 is installed on one side of the mounting frame 6.

[0020] In this embodiment, the focusing lens body 2 consists of a ferrule and a focusing lens. The alarm device body 3 uses a temperature sensor to measure the temperature of the lens to determine the degree of damage. When the temperature sensor receives the temperature transmitted from the focusing lens, it transmits it to the temperature control card via an electrical signal. The temperature control card communicates with the control board, which controls the transmission of signals for temperature alarms, cleaning, and replacement to the control panel. The panel displays the temperature and alarm information. The panel can also be set with temperature alarms for temperature differences, as well as signals for cleaning and replacement. The mounting base 1 provides installation conditions for the disassembly and assembly mechanism, the mounting bracket 6 provides installation conditions for the focusing lens body 2 and the alarm device body 3, and the two sliding rods 4 provide installation conditions for the two sliding cylinders 5. The alarm device body 3 can monitor the focusing lens body 2 and issue an alarm when replacement is required. When the focusing lens body 2 needs to be disassembled, the rotating disk 7 is rotated away from the fixing groove 8 by the fixing plate until the fixing plate is completely away from the fixing groove 8. Then, the mounting bracket 6 can be pulled, and the two sliding cylinders 5 can drive the mounting bracket 6 to move away from the mounting base 1 until the focusing lens body 2 on the mounting bracket 6 is completely removed from the mounting base 1. Then, the focusing lens body 2 can be replaced. Conversely, the focusing lens body 2 can be installed. This solves the problem that existing focusing lens modules are not easy to disassemble and replace.

[0021] Furthermore, the fixing plate includes a connecting rod 9 and a fixing rod 10. The connecting rod 9 is fixedly connected to the rotating disk 7 and is located on one side of the rotating disk 7. The fixing rod 10 is fixedly connected to the connecting rod 9 and is located on the connecting rod 9.

[0022] In this embodiment, the connecting rod 9 provides installation conditions for the fixing rod 10. The connecting rod 9 is the fixing rod 10 and the rotating disk 7. The fixing rod 10, in conjunction with the fixing groove 8, can limit the position of the mounting frame 6.

[0023] Furthermore, the disassembly and assembly mechanism also includes a locking block 11 and a first spring 12. The locking block 11 is slidably connected to the mounting frame 6 and passes through the mounting frame 6. The first spring 12 is fixedly connected to the locking block 11 and the mounting frame 6, and is located between the mounting frame 6 and the locking block 11.

[0024] In this embodiment, the fixing rod 10 has a fixing hole, and the locking block 11 is inserted into the mounting bracket 6 after passing through the fixing hole, so as to fix the fixing rod 10. The locking block 11 can be popped into the corresponding fixing hole by the rebound force of the first spring 12.

[0025] Furthermore, the disassembly and assembly mechanism also includes a pull handle 13 and an anti-slip sleeve 14. The pull handle 13 is fixedly connected to the locking block 11 and slidably connected to the mounting bracket 6, and passes through the mounting bracket 6. The anti-slip sleeve 14 is fixedly connected to the pull handle 13 and is located around the pull handle 13.

[0026] In this embodiment, pulling the handle 13 can cause the locking block 11 to move out of the fixing rod 10. The anti-slip sleeve 14 increases the friction of the handle 13, thereby improving the stability when pulling the handle 13.

[0027] Furthermore, the disassembly and assembly mechanism also includes two second springs 15, which are respectively fixedly connected to the mounting base 1 and to the two slide cylinders 5, and are all located between the slide cylinders 5 and the mounting base 1.

[0028] In this embodiment, the rebound force of the two second springs 15 can eject the mounting bracket 6 away from the mounting base 1 when it is in contact with the limiting position of the mounting bracket 6.

[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
