The protective baffle is disposed on the opposite side of the connection between the galvanometer assembly mounting base and the laser mounting base, and is connected to the galvanometer assembly mounting base. It is used to protect the galvanometer and block laser light emitted outside the working range of the laser. This invention can not only install and fix the laser and the galvanometer assembly, but also protect the galvanometer, and prevent laser leakage during the adjustment of the galvanometer.

[0004] Regarding the above-mentioned issues, the following technical defects were found: During the operation of existing equipment, when it is necessary to replace or maintain the laser cutting head, the cutting head is usually connected to the fixed seat using fasteners such as bolts and flanges. Because the existing technology requires the use of tools to repeatedly tighten and loosen multiple bolts to complete the disassembly and assembly, the operation steps are cumbersome and time-consuming, resulting in low efficiency of laser cutting head replacement and increased equipment downtime. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a positive electrode plate laser optical path fixing base.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positive electrode laser optical path fixing base, comprising a frame, a laser cutting head, a mounting plate, and a quick-connect device. The mounting plate is disposed on the inner wall of the frame, the quick-connect device is mounted on the surface of the mounting plate, and the laser cutting head is mounted on the surface of the quick-connect device. The quick-connect device includes a fixing post, which is fixedly connected to the surface of the mounting plate. The inner wall of the fixing post has several reserved slots, and a first spring is fixedly connected to the inner wall of each reserved slot. A locking block is fixedly connected to the other end of the first spring, and the locking block is slidably connected to the inner wall of the reserved slot.

An mounting post is fixedly connected to the other end of the positioning post, and the surface of the mounting post is fixedly connected to the laser cutting head.

[0007] The effect achieved by the above components is as follows: by setting up a quick-connect device, when the positioning post is inserted into the fixing post, the limiting block squeezes the locking block and compresses the first spring. After it is in place, the locking block pops out and locks the limiting block, realizing the quick locking of the laser cutting head and significantly improving the disassembly and assembly efficiency and connection reliability.

[0008] Preferably, the positioning post has a movable ring slidably connected to its arc surface, and a plurality of connecting posts are fixedly connected to the side of the movable ring away from the limiting block.

The surface of the movable ring is slidably connected to the locking block.

[0009] The effect achieved by the above components is as follows: during disassembly, by pulling the connecting plate, the movable ring is driven to compress the second spring, and the movable ring pushes the locking block to retract it into the reserved slot, so that the positioning post and the mounting post can be pulled out, which further simplifies the disassembly operation and improves the convenience of replacing the laser cutting head.

[0011] The aforementioned components achieve the following effects: during installation, pre-guidance and circumferential positioning are achieved through the sliding fit between the fixed plate and the mounting strip, and the sliding fit between the rotating plate and the fixed strip, preventing the mounting column from rotating relative to the fixed column, thus ensuring the accuracy of the laser cutting head's installation posture and repeatability.

[0012] Preferably, an auxiliary ring is fixedly connected to the end of the connecting plate away from the positioning post.

[0013] The effect achieved by the above components is that the operator can drive the connecting plate and the movable ring to move by applying force to the auxiliary ring, providing a convenient point of force for manually unlocking the quick-connect device, and further improving the ease of disassembly and the efficiency of operation.

[0015] The effect achieved by the above components is that the laser cutting head can swing along the arc through the mounting frame, realizing a wide range of adjustment of the cutting angle and enhancing the adaptability of the equipment to different workpiece positions. Preferably, connecting blocks are fixedly connected to both sides of the mounting frame, and sliding columns are fixedly connected to the surface of the connecting blocks. A sliding groove is formed on the surface of the frame, and the cross-sectional dimensions of the sliding groove are adapted to the inner wall dimensions of the limiting rail. The inner wall of the sliding groove is slidably connected to the arc surface of the sliding column. The surface of the connecting block is slidably connected to the inner wall of the frame. A clamping cap is threadedly connected to the arc surface of the sliding column, and the clamping cap abuts against the surface of the frame.

[0016] The above components achieve the following effects: loosening the clamping cap allows the mounting frame to slide smoothly along an arc-shaped trajectory, and tightening the clamping cap locks the mounting frame in any swing position, realizing manual and quick adjustment of the cutting angle and reliable locking.

[0017] Preferably, an ear plate is fixedly connected to the surface of the frame, a screw is threadedly connected to the surface of the ear plate, an auxiliary frame is fixedly connected to one end of the screw, a rotating shaft is rotatably connected to the inner wall of the auxiliary frame, and the arc surface of the rotating shaft is fixedly connected to the mounting frame.

[0018] The aforementioned components achieve the following effects: they enable fine-tuning of the laser cutting head angle, and with the help of the slide adjustment, the optical path direction can be precisely set, thus improving the positioning accuracy.

[0019] Preferably, the inner wall of the frame is provided with a translation device, the translation device including an auxiliary plate, the auxiliary plate being fixedly connected to the surface of the mounting frame, a lead screw being threadedly connected to the surface of the auxiliary plate, a movable frame being fixedly connected to one end of the lead screw, and slide bars being fixedly connected to both sides of the movable frame.

It works in conjunction with the adjustment device to complete multi-dimensional manual alignment of the optical path.

[0021] Preferably, a positioning strip is fixedly connected to the inner wall of the mounting frame, and positioning grooves are provided on both sides of the mounting plate, with the inner wall of the positioning groove slidably connected to the positioning strip.

[0022] The effect achieved by the above components is to provide linear guidance for the mounting plate during lifting and lowering, preventing the mounting plate from tilting or wobbling, and ensuring high linearity and stability of the laser cutting head's lifting and lowering movement.

[0023] Preferably, an indicator is fixedly connected to the surface of the mounting frame, and a ruler is fixedly connected to the surface of the mounting plate, with the ruler and the indicator surface being slidably connected.

[0024] The effect achieved by the above components is that the displacement can be read intuitively during the lifting and adjusting process, which makes it easier for the operator to accurately set the height of the laser cutting head, and significantly improves the intuitiveness of the adjustment and the accuracy of repeated positioning. Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by setting a quick-connect device, when the positioning post is inserted into the fixing post, the limiting block squeezes the locking block to compress the first spring. After it is in place, the locking block pops out and locks the limiting block, thereby achieving quick locking of the laser cutting head. When disassembling, pulling the connecting plate drives the movable ring to push the locking block back, and the positioning post can be pulled out, thereby achieving quick unlocking of the laser cutting head, which significantly improves the disassembly and assembly efficiency and connection reliability.

[0025] 2. In this invention, by setting an adjustment device, the mounting frame can swing along an arc trajectory by loosening the clamping cap, thereby achieving a wide range of adjustment of the cutting angle of the laser cutting head. After tightening the clamping cap, the position is locked. The screw thread fine-tuning drive shaft drives the mounting frame to rotate, thereby achieving precise angle setting and meeting the optical path alignment requirements of different workpiece positions.

[0026] 3. In this invention, by setting up a translation device, the screw is manually turned, and the movable frame is driven to slide smoothly along the guide rail through the threaded engagement between the screw and the auxiliary plate. This drives the mounting plate and the laser cutting head to move back and forth precisely and steplessly in the horizontal plane. The self-locking characteristic of the thread helps to maintain the position in time, thus achieving manual and precise alignment of the cutting position. Attached Figure Description

Detailed Implementation

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figure 1 As shown, the present invention provides a positive electrode laser optical path fixing base, including a frame 1, a laser cutting head 2, a mounting plate 3 and a quick-connect device 4. The mounting plate 3 is disposed on the inner wall of the frame 1, the quick-connect device 4 is mounted on the surface of the mounting plate 3, the laser cutting head 2 is mounted on the surface of the quick-connect device 4, the inner wall of the frame 1 is provided with an adjustment device 5, and the inner wall of the frame 1 is provided with a translation device 6.

[0032] The following is a detailed explanation of the specific setup and function of its quick-connect device 4, adjustment device 5, and translation device 6.

[0033] like Figures 2 to 5As shown, the quick-connect device 4 includes a fixing post 401, which is fixedly connected to the surface of the mounting plate 3. The inner wall of the fixing post 401 has several pre-drilled slots 411. A first spring 410 is fixedly connected to the inner wall of each pre-drilled slot 411. A locking block 409 is fixedly connected to the other end of the first spring 410. The locking block 409 is slidably connected to the inner wall of the pre-drilled slot 411. A positioning post 407 is slidably connected to the inner wall of the fixing post 401. A limit block 408 is fixedly connected to one end of the positioning post 407. The limiting block 408 has a trapezoidal cross-section and is slidably connected to the surface of the locking block 409. The other end of the positioning post 407 is fixedly connected to the mounting post 404. The surface of the mounting post 404 is fixedly connected to the laser cutting head 2. By setting the quick-connect device 4, when the positioning post 407 is inserted into the fixing post 401, the limiting block 408 squeezes the locking block 409 and compresses the first spring 410. After it is in place, the locking block 409 pops out and locks the limiting block 408, realizing the quick locking of the laser cutting head 2, which significantly improves the disassembly and assembly efficiency and connection reliability. The positioning post 407 has a movable ring 412 slidably connected to its arc surface. Several connecting posts 413 are fixedly connected to the side of the movable ring 412 away from the limiting block 408. A connecting plate 414 is fixedly connected to the arc surface of the connecting post 413. A second spring 416 is sleeved on the arc surface of the connecting post 413. The two ends of the second spring 416 are fixedly connected to the surface of the movable ring 412 and the inner wall of the mounting post 404. Several limiting grooves 417 are opened on the arc surface of the mounting post 404. The inner wall of the limiting groove 417 is slidably connected to the connecting plate 414. The surface of the movable ring 412 is slidably connected to the locking block 409. When disassembling, by pulling the connecting plate 414, the movable ring 412 is driven to compress the second spring 416. The movable ring 412 pushes the locking block 409 to retract into the reserved groove 411, so that the positioning post 407 and the mounting post 404 can be pulled out. This further simplifies the disassembly operation and improves the convenience of replacing the laser cutting head 2. Two fixing plates 402 are fixedly connected to the arc surface of the fixed column 401, and two fixing strips 403 are fixedly connected to the arc surface of the fixed column 401. Two rotating plates 405 are fixedly connected to the arc surface of the mounting column 404, and two mounting strips 406 are fixedly connected to the arc surface of the mounting column 404. The surfaces of the fixing plates 402 and the mounting strips 406 are slidably connected, and the surfaces of the rotating plates 405 and the fixing strips 403 are slidably connected. The cross-sections of the fixing plates 402 and the rotating plates 405 are both "L" shaped. During installation, the sliding fit between the fixing plates 402 and the mounting strips 406, and the sliding fit between the rotating plates 405 and the fixing strips 403 are used for pre-guidance and circumferential positioning to prevent the mounting column 404 from rotating relative to the fixed column 401, thus ensuring the accuracy of the installation posture and the repeatability of the laser cutting head 2. An auxiliary ring 415 is fixedly connected to the end of the connecting plate 414 away from the positioning post 407. When the operator applies force to the auxiliary ring 415, the connecting plate 414 and the movable ring 412 can be driven to move, providing a convenient point of force for manually unlocking the quick-connect device 4, and further improving the ease of disassembly and the efficiency of operation.

[0034] like Figure 6 and Figure 7 As shown, the positioning device 5 includes a limiting rail 501, which is fixedly connected to the inner wall of the frame 1. The cross-section of the limiting rail 501 is arc-shaped. A positioning block 502 is slidably connected to the surface of the limiting rail 501. A mounting frame 503 is fixedly connected to the surface of the positioning block 502. The mounting plate 3 is located on the inner wall of the mounting frame 503, allowing the laser cutting head 2 to swing along the arc through the mounting frame 503, thereby realizing a wide range of adjustment of the cutting angle and enhancing the adaptability of the equipment to different workpiece positions. Both sides of the mounting frame 503 are fixedly connected to connecting blocks 504. The surface of the connecting blocks 504 is fixedly connected to sliding columns 507. The surface of the frame 1 is provided with a sliding groove 505. The cross-sectional dimensions of the sliding groove 505 are adapted to the inner wall dimensions of the limiting rail 501. The inner wall of the sliding groove 505 is slidably connected to the arc surface of the sliding column 507. The surface of the connecting block 504 is slidably connected to the inner wall of the frame 1. The arc surface of the sliding column 507 is threadedly connected to a clamping cap 506. The clamping cap 506 abuts against the surface of the frame 1. Loosening the clamping cap 506 allows the mounting frame 503 to slide smoothly along the arc trajectory. Tightening the clamping cap 506 locks the mounting frame 503 in any swing position, realizing manual and quick adjustment and reliable locking of the cutting angle. The surface of the frame 1 is fixedly connected to an ear plate 508, and the surface of the ear plate 508 is threadedly connected to a screw 509. One end of the screw 509 is fixedly connected to an auxiliary frame 510, and the inner wall of the auxiliary frame 510 is rotatably connected to a rotating shaft 511. The arc surface of the rotating shaft 511 is fixedly connected to the mounting frame 503, which realizes the fine adjustment of the angle of the laser cutting head 2. With the adjustment of the slide groove 505, the optical path direction can be accurately set, improving the positioning accuracy.

[0035] like Figure 8 and Figure 9As shown, the translation device 6 includes an auxiliary plate 601, which is fixedly connected to the surface of the mounting frame 503. A lead screw 602 is threadedly connected to the surface of the auxiliary plate 601. A movable frame 603 is fixedly connected to one end of the lead screw 602. Slide bars 606 are fixedly connected to both sides of the movable frame 603. Two connecting plates 604 are fixedly connected to the lower surface of the mounting plate 3. Guide rails 605 are fixedly connected to the side of the two connecting plates 604 that are close to each other. The inner wall of the guide rail 605 is slidably connected to the surface of the slide bar 606. By setting the translation device 6, the mounting plate 3 and the laser cutting head 2 can achieve precise stepless translation in the front and back directions. The adjustment process has a clear manual feedback feel, and the position is maintained in time by means of the thread self-locking characteristic. It works in conjunction with the positioning device 5 to complete multi-dimensional manual optical path alignment. A positioning strip 609 is fixedly connected to the inner wall of the mounting frame 503. Positioning grooves 610 are provided on both sides of the mounting plate 3. The inner wall of the positioning groove 610 is slidably connected to the positioning strip 609. During lifting and lowering, the mounting plate 3 is linearly guided to prevent lateral deviation or swaying, ensuring high linearity and stability of the lifting and lowering movement of the laser cutting head 2. An indicator 607 is fixedly connected to the surface of the mounting frame 503, and a scale 608 is fixedly connected to the surface of the mounting plate 3. The scale 608 is slidably connected to the surface of the indicator 607. During lifting and lowering adjustment, the displacement can be read intuitively, making it easy for the operator to accurately set the height of the laser cutting head 2, significantly improving the intuitiveness of adjustment and the accuracy of repeatable positioning.

[0036] The overall working principle is as follows: by setting up the quick-connect device 4, when the laser cutting head 2 needs to be installed, the rotating plate 405 on the mounting post 404 is first aligned with the fixing strip 403, and the fixing plate 402 is aligned with the mounting strip 406 for pre-guidance. Then, the positioning post 407 is inserted into the fixing post 401. At this time, the trapezoidal inclined surface of the limiting block 408 presses against the locking block 409. The locking block 409 slides along the reserved groove 411 and compresses the first spring 410. After the limiting block 408 has completely passed through, the first spring 410 pushes the locking block 409 to spring back. The end face of the locking block 408 is pulled out to quickly lock the laser cutting head 2. When disassembly is required, the auxiliary ring 415 is manually pulled to drive the connecting plate 414 to slide along the limiting groove 417. The connecting plate 414 pulls the movable ring 412 through the connecting column 413 to compress the second spring 416. The end face of the movable ring 412 pushes the locking block 409 to retract into the reserved groove 411. The locking block 409 is disengaged from the limiting block 408, and the positioning column 407 can be pulled out from the fixed column 401 to quickly unlock the laser cutting head 2.

[0037] By setting the adjustment device 5, when it is necessary to adjust the cutting angle of the laser cutting head 2, first manually loosen the clamping cap 506 so that the clamping cap 506 is loosened from the surface of the frame 1. At this time, the sliding column 507 on the connecting block 504 on both sides of the mounting frame 503 can slide freely in the slide groove 505. The operator pushes the mounting frame 503, and the positioning block 502 slides along the arc-shaped limit rail 501. The mounting frame 503 drives the mounting plate 3 and the laser cutting head 2 to swing along the arc, realizing a wide range of angle adjustment. After the initial adjustment is in place, tighten the clamping cap 506 to press against the surface of the frame 1 to complete the locking. If fine adjustment is required, rotate the screw 509. The screw 509 feeds in the thread in the ear plate 508. Through the auxiliary frame 510, drive the rotating shaft 511 to drive the mounting frame 503 to rotate slightly around the rotating shaft 511, realizing the precise setting of the angle and meeting the optical path alignment requirements of different workpiece positions.

[0038] By setting up the translation device 6, when it is necessary to adjust the front and rear cutting position of the laser cutting head 2, the lead screw 602 is manually turned. The lead screw 602 feeds into the internal thread of the auxiliary plate 601 fixed to the mounting frame 503. The end of the lead screw 602 pushes the movable frame 603. The slide bars 606 on both sides of the movable frame 603 slide smoothly along the guide rail 605 on the connecting plate 604. The movable frame 603 drives the mounting plate 3 to translate back and forth along the guide direction of the positioning bar 609 and the positioning groove 610. When the mounting plate 3 moves, the scale 608 on its surface slides relative to the indicator 607 on the mounting frame 503. The operator reads the displacement in real time through the scale 608. The laser cutting head 2 achieves fine stepless translation in the horizontal plane with the mounting plate 3. After the adjustment is in place, the position is immediately maintained by the self-locking characteristic of the thread of the lead screw 602 and the auxiliary plate 601, thus completing the manual and precise alignment of the cutting position.
