Description

Technical Field

[0001] This invention relates to the field of laser tube module technology, and in particular to a laser tube module that does not require dimming. Background Technology

[0002] In modern industrial manufacturing, laser equipment is widely used in precision processing processes such as cutting, marking, and engraving. As the core component at the end of the equipment, the laser module is usually composed of an upper laser generating unit and a lower optical adjustment head. Due to the complex processing environment, the lower optical focusing lens is easily contaminated by dust or processing fumes. During the daily operation cycle of the equipment, the lower optical adjustment head must be disassembled regularly for cleaning and maintenance or replaced as a whole.

[0003] Traditional laser optical components are typically fastened with multiple bolts or directly screwed together with large-area threads during assembly. This connection method is highly dependent on auxiliary tools during disassembly and assembly, and the operation process is time-consuming and cumbersome. More importantly, the threaded fit and flush flange docking structure inevitably have mechanical manufacturing tolerances and fit clearances. After repeated disassembly and re-tightening, the mating surfaces of the upper and lower components are prone to microscopic assembly misalignment, resulting in the loss of concentricity of the internal optical path.

[0004] This optical axis deviation caused by mechanical disassembly and assembly gaps will directly cause the high-energy laser beam to deviate from the predetermined optical center point, seriously affecting the final processing accuracy and energy focusing effect. In order to correct the deviation caused by assembly, maintenance personnel must spend a lot of time performing complicated manual optical path fine-tuning and center calibration after each reassembly. This not only greatly increases the later maintenance cost of the equipment, but also seriously restricts the continuous processing efficiency of the automated production line.

[0005] Therefore, this invention proposes a dimming-free laser tube module to address the shortcomings of existing technologies. Summary of the Invention

[0006] In view of the problems in the existing technology of laser tube modules, such as the excessive reliance on auxiliary fastening tools for splicing and disassembling laser optical components, which are cumbersome to operate, and the easy formation of mechanical gaps at the mating surfaces of upper and lower components after repeated disassembly and re-locking, which leads to the loss of internal optical path concentricity and repeatability accuracy, requiring a lot of time for subsequent manual fine-tuning and calibration, this invention aims to provide a laser tube module with an improved structure that can effectively solve the above problems without dimming.

[0007] The present invention provides a laser tube module that does not require dimming, comprising: a frame, and a processing assembly fixedly installed on the top of the frame, the processing assembly including a laser module and an adjustment head disposed directly below the laser module; and a connecting mechanism.

[0008] The connecting mechanism includes a male head, a female head, and a movable column. The male head has a core inside and a slot on its outer wall. The female head has a plug hole inside that matches the core.

[0009] Furthermore, the bottom end of the laser module and the top end of the adjustment head are connected by the connecting mechanism. The specific combination and cooperation state is as follows: the male head is fixedly installed on the bottom surface of the laser module, the female head is fixedly installed on the top surface of the adjustment head, the movable column slides through the inside of the wall of the female head, and the end of the movable column is stably engaged in the slot; at the same time, the core is inserted into the insertion hole in the forward direction, and the inner core of the core and the inner core of the female head form a tight fit in space.

[0010] The movable column itself has structural flexibility. When an external force is applied to press the movable column, causing it to move spatially and retract into the inner wall clearance area of ​​the male head, the physical and mechanical obstruction between the movable column and the slot is released, thereby enabling the laser module and the adjustment head to be pulled out and separated without obstruction.

[0011] The dimming-free laser tube module also includes a frame and a clamping mechanism. The frame is fixedly connected to the machine frame, and the clamping mechanism is installed on the frame and its overall spatial position is directly below the adjustment head. It is used to perform precise lateral clamping and centering alignment of the workpiece to be processed before formal cutting and marking.

[0012] The clamping mechanism specifically includes a cylinder, a rotating column, and a connecting rod. The cylinder is fixedly installed on the inner wall area of ​​the frame, and the rotating column is rotatably connected to the center position of the frame foundation plate. The linear power output end of the cylinder is connected to the connecting rod by a hinge to transmit the push-pull driving load.

[0013] The connecting rod is specifically a cylindrical rod of equal length and symmetrically distributed on both sides of the rotating column. The inner ends of the connecting rod are rotatably connected to both sides of the rotating column by pins to ensure smooth mechanical conversion during the transmission of the central driving force to both sides.

[0014] The clamping mechanism also includes a mounting plate, which is slidably connected to the guide surface of the frame and is securely connected to the outer ends of the connecting rods respectively. When the connecting rods are subjected to force and swing, they can precisely drive the mounting plates on both sides to slide synchronously and equidistantly along a straight path.

[0015] The mounting plate is fixedly equipped with clamping columns that directly contact the external workpiece. The clamping columns are arranged in parallel to each other and are used to physically squeeze and position the workpiece laterally. This ensures that regardless of whether the initial placement position of the workpiece to be processed has shifted laterally, it can be forcibly centered with the center line of the conveyor line as the absolute reference to achieve precise and unbiased positioning.

[0016] The frame is based on a high-rigidity box-type steel structure. The bottom of the frame is equipped with adjustable support feet, which are directly threaded into holes at the bottom of the frame. This allows for independent adjustment of the height of each corner on uneven workshop surfaces, providing a horizontal and vibration-resistant stable mounting base for the core optical components and linkage mechanisms above. This invention discloses a laser tube module that does not require dimming. 1. This invention solves the problem in the prior art where the disassembly and assembly of laser optical components is cumbersome and repeated assembly easily produces mechanical gaps, resulting in poor optical path reset accuracy. It achieves the technical effect of quick pressing to unlock and automatic spring-loaded locking without the need for fastening tools. At the same time, the precise guiding insertion of the male and female inner cores ensures extremely high optical path concentricity and repeatable positioning accuracy after multiple disassembly and assembly, eliminating the cumbersome process of subsequent optical path fine-tuning.

[0017] 2. This invention solves the problem in existing technologies where the clamping of the workpiece during the feeding stage is prone to unilateral force deviation and difficulty in accurate centering and alignment. It achieves the technical effect of converting unidirectional driving force into a linear closing motion of the clamping columns on both sides that is absolutely synchronous and equidistant. Regardless of how the initial placement position of the workpiece is laterally offset, it can forcefully push and clamp it to the reference position of the conveying center line, thereby eliminating clamping deviation at the source and greatly improving the processing positioning accuracy.

[0018] 3. This invention, by employing a high-rigidity box-type steel structure as the overall frame and configuring threaded adjustable support feet at the bottom corners of the frame, solves the problem that existing laser processing equipment is difficult to level quickly on complex or uneven workshop floors and is easily affected by external vibrations. It achieves the technical effect of being able to independently adjust the height of each support point to quickly maintain the overall level of the equipment, providing a stable bearing foundation that is resistant to bending and torsion for the optical processing device and motion transmission components above, effectively isolating external vibrations and ensuring the verticality of the processing.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example: Reference Figures 1 to 5 The present invention provides a laser tube module that does not require dimming, which aims to solve the problems in the prior art where the disassembly and assembly of laser optical components are cumbersome and repeated assembly can easily generate mechanical gaps that lead to poor optical path reset accuracy, and the workpiece clamping during the feeding process is prone to unilateral force deviation and difficulty in centering and aligning.

[0024] like Figure 1 and Figure 2 As shown, the dimming-free laser tube module includes a frame 1 and a processing component 2 fixedly mounted on top of the frame 1. The frame 1 adopts a box-type steel structure design and has adjustable support feet threaded to the bottom. The frame 1 serves as the supporting foundation for the entire laser equipment, providing an installation reference for each component. The processing component 2 includes a laser module 21 and an adjustment head 22 located directly below the laser module 21. The laser module 21 emits high-energy laser light, and the adjustment head 22 focuses and collimates the laser beam. The bottom end of the laser module 21 and the top end of the adjustment head 22 are connected by a connecting mechanism 4, which enables the physical connection and optical path conduction between the adjustment head 22 and the laser module 21.

[0025] Combination Figure 4 and Figure 5 The connecting mechanism 4 includes a male connector 41, a female connector 44, and a movable column 43. The male connector 41 is fixedly installed on the bottom surface of the laser module 21, and the female connector 44 is fixedly installed on the top surface of the adjusting head 22. The outer wall of the male connector 41 has a slot, and the two side walls of the female connector 44 have guide holes. The movable column 43 slides symmetrically through the guide holes, and the inner end of the movable column 43 engages in the slot. The male connector 41 has a core 42 inside, and the female connector 44 has a plug hole that matches the core 42 inside. The core 42 is inserted into the plug hole, and the inner core matches the inner core of the female connector 44 to achieve optical path docking. An elastic reset member is sleeved between the movable column 43 and the female connector 44, and the elastic reset member provides a pre-tightening force for the movable column 43 to engage in the slot. The middle of the rod of the movable column 43 has a narrow neck section for clearance, and the outer end of the movable column 43 protrudes from the outer side wall of the female connector 44 under normal conditions.

[0026] like Figure 3 As shown, the dimming-free laser tube module also includes a frame 36 and a clamping mechanism 3. The frame 36 is fixedly connected to the frame 1, and the clamping mechanism 3 is integrally mounted on the frame 36, with its spatial position directly below the adjusting head 22. The clamping mechanism 3 includes a cylinder 35, a rotating column 34, a connecting rod 33, a mounting plate 32, and a clamping column 31. The cylinder 35 is fixedly mounted on the inner wall of the frame 36, and the rotating column 34 is rotatably connected to the center of the bottom plate of the frame 36. The connecting rod 33 is a cylindrical rod of equal length and symmetrically distributed on both sides of the rotating column 34. The output end of the cylinder 35 is hinged to the middle of the connecting rod 33 on one side by a pin, and the inner ends of the connecting rod 33 are rotatably connected to both sides of the rotating column 34 by pins. A straight guide groove is provided on the top surface of the frame 36, and the bottom of the mounting plate 32 slides within the straight guide groove. The mounting plate 32 is hinged to the outer ends of the corresponding connecting rods 33. The clamping posts 31 are fixedly installed on the opposite surfaces of the mounting plate 32. The clamping posts 31 are arranged in parallel to each other for lateral clamping and positioning of the workpiece.

[0027] Working Principle: The frame 1 adopts a box-type steel structure design and has adjustable support feet connected by threads at the bottom. The frame 1 serves as the load-bearing foundation for the entire laser equipment, providing an installation reference for all components. Before performing the processing operation, the clamping mechanism 3 laterally centers the workpiece to be processed. The cylinder 35 is activated, its piston rod extends and pushes the hinged single-sided connecting rod 33, causing the connecting rod 33 to rotate around the rotating column 34. Through the linkage structure formed by the central rotating column 34 and the two connecting rods 33, the power is transmitted to the other connecting rod 33, driving the two mounting plates 32 to slide towards each other along the straight guide groove of the frame 36. The two clamping columns 31 then close inward to fit against the side wall of the workpiece, and the workpiece is pushed to the center line of the conveyor line by the equidistant displacement on both sides, completing the clamping and limiting.

[0028] After the workpiece is clamped, the processing assembly 2 begins operation. The laser module 21 emits a high-energy laser beam, which passes through the male connector 41 and the core 42 and is transmitted downwards into the adjustment head 22. When the adjustment head 22 needs to be disassembled for maintenance, the operator presses the outer end of the movable column 43 in the connecting mechanism 4 from both sides inwards. The movable column 43 slides inwards against the elastic force of the elastic reset member, and the narrow neck section on it moves to the slot position of the male connector 41, avoiding spatial interference. Then the adjustment head 22 can be pulled out downwards along with the female connector 44 to complete the separation. During reassembly, the female connector 44 is aligned with the male connector 41 and pushed upwards, and the core 42 is inserted into the insertion hole; the movable column 43 is released, and under the action of the elastic reset member, the movable column 43 pops out and re-locks into the slot, completing the automatic locking.
