Description

Technical Field

[0001] This utility model relates to the technical field of coding machines, and in particular to a novel laser coding machine. Background Technology

[0002] Laser marking technology, as an important technical means in the field of modern industrial marking, has been widely used in various industries such as electronic devices, plastic products, metal materials, and packaging containers. Laser marking technology is an advanced processing method that uses a high-energy-density laser beam to permanently mark the surface of various materials. Its basic principle is that through the interaction between the laser and the material surface, the surface material undergoes evaporation, chemical and physical changes, or partial ablation, thereby etching the desired patterns, text, or codes.

[0003] In actual operation, after a laser marking machine finishes marking a single material, the operator must manually replace the marked material so that the machine can continue marking the next material. However, this material replacement process is time-consuming, making it difficult to smoothly connect the entire marking process and resulting in low work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a novel laser marking machine to solve the problems mentioned in the background section.

[0005] The technical solution adopted in this utility model is:

[0006] A novel laser marking machine includes a worktable. A lifting frame is fixedly connected to the top of the worktable. A cylinder is slidably connected to one end of the lifting frame. A connecting block is fixedly connected to the telescopic end of the cylinder. A marking device is provided at the bottom of the connecting block. A rotating groove is provided on the top of the worktable. A slot is provided inside the rotating groove. A locking block fits inside the slot. A connecting rod is fixedly connected to one end of the locking block. A flat plate is fixedly connected to the top of the connecting rod. A cylinder is fixedly connected to the bottom of the flat plate. A spring is provided inside the cylinder. A fixing block is fixedly connected to the bottom of the spring. Fixed platforms are fixedly connected to both sides of the flat plate.

[0007] In some embodiments, a circular block is fixedly connected to the center of the rotating groove, a bearing is fixedly connected to the top of the circular block, and the inner ring of the bearing is fixedly connected to the fixed block.

[0008] In some embodiments, the telescopic range of the fixed block is three centimeters, and the height of the rotating groove is two centimeters.

[0009] In some embodiments, the card block is rectangular in shape and is adapted to the card slot.

[0010] In some embodiments, the top of the fixed platform is provided with sliding grooves on both sides, a movable block is slidably connected inside the sliding groove, a clamp is fixedly connected to the top of the movable block, a lead screw is threadedly connected inside the movable block, and a knob is fixedly connected to one end of the lead screw.

[0011] In some embodiments, anti-slip protrusions are provided on the contact surfaces of the fixing platform and the clamping plate.

[0012] In some embodiments, the cylinder and the fixing block are coaxially arranged, and the extension and retraction direction of the spring is consistent with the axial direction of the cylinder.

[0013] In some embodiments, the threads at both ends of the lead screw have opposite directions, and the moving blocks are symmetrically arranged and threadedly engaged with the lead screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (I) In use, place the processed material on one end of the flat plate's fixed platform, positioning it below the coding machine. Place the material to be processed on the other end's fixed platform. When switching platforms is needed after processing one end's material, press down on the flat plate to compress the spring and retract the fixed block into the cylinder. Simultaneously, rotate the flat plate, which, through a connecting rod, drives the locking block to slide in the slot of the rotating groove, thus achieving rotation. After rotation, release the flat plate, the spring returns to its original position, and the locking block engages in the slot, completing the change of the fixed platform position for coding the next material. This design is efficient and convenient, ensuring coding accuracy and equipment stability. By quickly switching the fixed platform position through pressing down and rotating the flat plate, efficient and continuous coding operations are achieved, making it particularly suitable for batch production scenarios and significantly improving production speed.

[0016] (II) The fixed platform is fixed on both sides of the flat plate. The top of the fixed platform has sliding grooves on both sides. The movable block is slidably connected within the sliding grooves. A clamping plate is fixedly connected to the top of the movable block. A lead screw is threaded into the movable block, and a knob is fixedly connected to one end of the lead screw. When it is necessary to clamp the material, the knob is rotated, causing the lead screw to rotate. Because the lead screw and the movable block are threaded together, and the sliding grooves restrict the rotational movement of the movable block, the movable block moves linearly along the sliding grooves, thereby moving the clamping plate to clamp or release the material.

Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Currently, in practical operation, laser marking machines require manual replacement of the marked material after marking a single item so that the machine can continue marking the next item. This material replacement process is time-consuming, hindering the smooth flow of the marking process and resulting in low work efficiency.

[0026] like Figure 1-4 As shown, this utility model embodiment provides a novel laser marking machine, including a worktable 1. A lifting frame 101 is fixedly connected to the top of the worktable 1. A cylinder 102 is slidably connected to one end of the lifting frame 101. A connecting block 103 is fixedly connected to the telescopic end of the cylinder 102. A marking device 104 is provided at the bottom of the connecting block 103. A rotating groove 2 is provided at the top of the worktable 1. A slot 201 is provided inside the rotating groove 2. A locking block 209 is fitted inside the slot 201. A connecting rod 208 is fixedly connected to one end of the locking block 209. A flat plate 207 is fixedly connected to the top of the connecting rod 208. A cylinder 205 is fixedly connected to the bottom of the flat plate 207. A spring 206 is provided inside the cylinder 205. A fixing block 204 is fixedly connected to the bottom of the spring 206. Fixed platforms 3 are fixedly connected to both sides of the flat plate 207.

[0027] The new laser marking machine uses a worktable 1 as its supporting base, with a lifting frame 101 fixed to the top of the worktable 1. A cylinder 102 can slide along the lifting frame 101 to achieve initial height adjustment. When the marking height needs to be adjusted, the operator can move the cylinder 102 to a suitable position. The telescopic end of the cylinder 102 is fixedly connected to a connecting block 103. When the cylinder 102 operates, its telescopic end drives the connecting block 103 to reciprocate up and down. The marking device 104 is located at the bottom of the connecting block 103 and moves synchronously with the connecting block 103, thereby enabling marking operations on workpieces at different heights. The specific models of the lifting frame 101 and the marking device 104 are LAS-LJ101 and LAS-DM104, respectively.

[0028] In use, the processed material is placed on one end of the fixed platform 3 of the flat plate 207 and positioned below the coding device 104. The material to be produced (metal nameplate, instrument shell) is placed on the other end of the fixed platform 3. When it is necessary to switch materials, the flat plate 207 is pressed down to compress the spring 206 and retract the fixed block 204 into the cylinder 205. At this time, the locking block 209 disengages from the locking slot 201 of the rotating groove 2. Then, the flat plate 207 is rotated (without continuous pressing). The locking block 209 is driven to slide in the arc track of the rotating groove 2 through the connecting rod 208. When rotated 180 degrees (the two symmetrically arranged locking slots 201 ensure positioning accuracy), the locking block 209 will align with the opposite locking slot 201. After the flat plate 207 is released, the spring 206 returns to its original position, causing the locking block 209 to snap into the locking slot 201 to complete the fixation, thus realizing the precise position switching of the fixed platform 3. This design, through the guiding function of the rotating groove 2 and the positioning function of the card slot 201, ensures both precise 180-degree rotation and coding accuracy and equipment stability.

[0029] The manual pressing down of the rotating flat plate 207 switches the position of the fixed stage 3. It does not require a complex mechanical transmission structure, is simple and quick to operate, and can perform continuous coding operations, which can significantly improve production speed.

[0030] Furthermore, a circular block 202 is fixedly connected to the middle of the rotating groove 2, and a bearing 203 is fixedly connected to the top of the circular block 202. The inner ring of the bearing 203 is fixedly connected to the fixed block 204.

[0031] The circular block 202 in the middle of the rotating groove 2 serves as the rotation center, and the inner ring of the bearing 203 at its top is fixedly connected to the fixed block 204, so that the flat plate 207 rotates around the bearing 203 through the cylinder 205 and the fixed block 204.

[0032] The bearing 203 reduces rotational friction, ensuring smooth rotation of the flat plate 207, while the circular block 202 provides a stable fulcrum for rotation, improving the ease of adjusting the position of the fixed platform 3.

[0033] Furthermore, the extension range of the fixed block 204 is three centimeters, and the height of the rotating groove 2 is two centimeters.

[0034] When the flat plate 207 is subjected to downward pressure, the fixing block 204 is subjected to downward force, compressing the spring 206 and causing the fixing block 204 to partially retract into the cylinder 205. The extension range of the fixing block 204 is designed to be three centimeters, which, together with the rotating groove 2 with a height of two centimeters, restricts the vertical displacement of the flat plate 207 and prevents the spring 206 from being over-compressed or separated.

[0035] Furthermore, the shape of the card block 209 is rectangular and it is adapted to the card slot 201.

[0036] The rectangular card block 209 matches the shape of the card slot 201, and after being inserted, it restricts the movement of the flat plate 207.

[0037] Furthermore, the top of the fixed platform 3 is provided with sliding grooves 301 on both sides, and a moving block 303 is slidably connected inside the sliding groove 301. A clamping plate 302 is fixedly connected to the top of the moving block 303, and a lead screw 304 is threadedly connected inside the moving block 303. A knob 305 is fixedly connected to one end of the lead screw 304.

[0038] The fixed platform 3 is fixed on both sides of the flat plate 207. The top of the fixed platform 3 has sliding grooves 301 on both sides. A movable block 303 is slidably connected within the sliding grooves 301. A clamping plate 302 is fixedly connected to the top of the movable block 303. A lead screw 304 is threadedly connected inside the movable block 303, and a knob 305 is fixedly connected to one end of the lead screw 304. When it is necessary to clamp materials, the knob 305 is rotated, causing the lead screw 304 to rotate. Because the lead screw 304 and the movable block 303 are threadedly engaged, and the sliding grooves 301 restrict the rotational movement of the movable block 303, the movable block 303 moves linearly along the sliding grooves 301, thereby moving the clamping plate 302 and achieving the clamping or releasing of materials (metal nameplates, instrument housings).

[0039] Furthermore, anti-slip protrusions are provided on the contact surfaces of the fixed platform 3 and the clamping plate 302.

[0040] When the clamping plate 302 clamps the workpiece onto the fixed platform 3, the anti-slip protrusions contact the workpiece surface, increasing the friction between the fixed platform 3 and the clamping plate 302 on the workpiece.

[0041] Furthermore, the cylinder 205 and the fixing block 204 are coaxially arranged, and the extension and retraction direction of the spring 206 is consistent with the axial direction of the cylinder 205.

[0042] When the rotating knob 305 drives the lead screw 304 to rotate, since the threads at both ends of the lead screw 304 rotate in opposite directions, the two symmetrically arranged moving blocks 303 will move in opposite directions at the same time, thereby driving the two clamping plates 302 to move to the middle or both sides at the same time, so as to quickly clamp or release the material.

[0043] Furthermore, the threads at both ends of the lead screw 304 rotate in opposite directions, and the moving blocks 303 are symmetrically arranged and threadedly engaged with the lead screw 304.

[0044] The screw 304 drives the symmetrical moving blocks 303 to move synchronously in opposite directions or in opposite directions, thereby realizing the synchronous opening and closing of the clamping plate 302.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
