[0001] This invention relates to the field of laser engraving technology, and in particular to an assembly fixture and laser engraving system based on laser engraving equipment. Background Technology

[0002] Laser marking technology is an emerging process for marking products, widely used in the production processes of body-in-white production lines, especially in the manufacturing, repair, and traceability of body parts. When marking different products, the large number of products often necessitates the purchase of numerous laser marking machines, leading to high procurement and maintenance costs, and also wasting the flexibility of the marking capabilities of the equipment. However, most laser marking machines currently on the market cannot be adjusted or replaced after installation. Different products sometimes require different positions and positioning fixtures, which conventional laser marking fixtures cannot simultaneously meet, or sometimes the laser marking equipment is used exclusively for fixing products. Therefore, there is an urgent need to design a fixture that is ingeniously structured, easy to operate, and allows for quick assembly of laser marking equipment. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art.

[0023] The following is for reference. Figures 1 to 5 This invention describes an assembly fixture and laser marking system based on a laser marking device according to an embodiment of the present invention.

[0024] like Figures 1 to 5 As shown, the assembly fixture based on the laser marking equipment according to the first aspect of the present invention can be applied to the laser marking system. The assembly fixture of this embodiment has the advantages of ingenious structural design, convenient operation and low cost. It can not only quickly assemble the laser marking equipment 100 with automotive parts, but also quickly switch between different automotive parts to be marked by using different assembly fixtures, and effectively match the automotive parts with the laser marking equipment 100, so as to achieve fast and accurate positioning of the laser marking equipment 100. It effectively solves the problem of purchasing a large number of laser marking equipment 100 due to the increase in the number of automotive parts, and has a good application prospect.

[0025] like Figures 1 to 5 As shown, the assembly fixture based on the laser engraving equipment includes an equipment base 200 and a product positioning mechanism 300.

[0026] The equipment base 200 serves to mount the laser engraving equipment 100 and cooperates with the product positioning mechanism 300. The equipment base 200 includes a positioning part 220 and a mounting part 210. The mounting part 210 is used for fixed connection with the laser engraving equipment 100. Specifically, the mounting part 210 is fixedly connected to the laser engraving equipment 100 by bolts. The mounting part 210 has a support surface and two limiting surfaces extending in the left-right direction, located on the front and rear sides of the support surface, respectively. The laser engraving equipment 100 is attached to the support surface and the two limiting surfaces, and then installed by bolts. The positioning part 220 is located below the mounting part 210, and the positioning part 220 is fixedly connected to the mounting part 210 by bolts. The positioning part 220 has a channel 230 for the laser from the laser engraving equipment 100 to pass through, and the channel 230 extends vertically through the entire structure.

[0027] It is understood that the specific shape and structure of the mounting part 210 and the positioning part 220 can be designed according to the actual situation, and are not specifically limited here. Both the mounting part 210 and the positioning part 220 are composed of multiple metal plates. In this embodiment, the cross-sectional shape of the channel 230 is rectangular. The mounting part 210 is located on the upper side of the positioning part 220, and is located on the left or right side of the positioning part 220. The mounting part 210 and the positioning part 220 are connected by bolts. After the laser marking device 100 is fixedly connected to the mounting part 210, the laser head 110 of the laser marking device 100 is located above the channel 230 and can emit a high-energy laser beam vertically downwards. The laser beam can propagate downwards along the channel 230. The lower surface of the positioning part 220 is a first positioning surface, which extends horizontally. The lower end of the positioning part 220 is provided with second positioning surfaces on both the front and rear sides, which extend horizontally. The lower end of the positioning part 220 is provided with third positioning surfaces on both the left and right sides, which extend horizontally.

[0028] In addition, the mounting section 210 is provided with U-shaped handles 250 on both the front and rear sides, making it convenient for workers to move the equipment base 200 using the handles 250. Furthermore, the positioning section 220 is provided with a pipe 240 on one side in the front-rear direction. One end of the pipe 240 is connected to the channel 230, and the other end of the pipe 240 is open to the outside atmosphere, so that the metal fumes generated during the laser engraving process can be discharged outside the assembly fixture through the pipe 240.

[0029] The product positioning mechanism 300 is used for mounting automotive parts and is configured to cooperate with the equipment base 200. The product positioning mechanism 300 includes a product base 310, a magnetic attraction mechanism 320, and a clamping mechanism. The product base 310 has a through hole 312 extending vertically and allowing the laser from the laser marking equipment 100 to pass through. The upper end of the product base 310 has a guide portion that is adapted to and detachably connected to the positioning portion 220 for positioning the equipment base 200. The lower end of the product base 310 has positioning pins 340, which are used for fitting and inserting with the automotive parts. Several positioning pins 340 are provided and extend vertically. In this embodiment, the through hole 312 is rectangular when viewed vertically. There are two locating pins 340, located on the left and right sides of the product base 310 respectively, and the cross-sectional shape of the locating pins 340 is circular.

[0030] A magnetic attraction mechanism 320 is fixedly mounted on the product base 310. The magnetic attraction mechanism 320 is configured to magnetically attract automotive parts located below it. Specifically, the product base 310 has a horizontally positioned positioning surface perpendicular to the extending direction of the positioning pin 340. Several magnetic attraction mechanisms 320 are located above the positioning surface and are configured to magnetically attract automotive parts so that the upper surface of the automotive parts can fit against the positioning surface. Understandably, by connecting the positioning pin 340 to the automotive component, the automotive component is positioned on a horizontal plane relative to the product base 310. The magnetic attraction mechanism 320 magnetically attracts the automotive component, causing it to adhere tightly to the positioning surface under the upward magnetic force. This achieves vertical positioning of the automotive component relative to the product base 310 and pre-fixes the automotive component relative to the product base 310, facilitating subsequent stable clamping.

[0031] In one specific embodiment, the magnetic attraction mechanism 320 is an electromagnet, and the electromagnet is fixedly connected to the product base 310. Two electromagnets are provided, and the two electromagnets are located on the left and right sides of the product base 310, respectively. It can be understood that by controlling the on and off state of the electromagnet, the electromagnet can be controlled to generate or demagnetize the automotive parts.

[0032] In another specific embodiment, the magnetic attraction mechanism 320 is a magnetic base, and the magnetic base is fixedly connected to the product base 310. Two magnetic bases are provided, and they are located on the left and right sides of the product base 310, respectively. It is understood that the magnetic base has a knob, which allows the operator to apply or remove the magnetic attraction to the automotive parts by rotating the knob. Magnetic bases are prior art, and those skilled in the art should clearly understand their specific structure and working principle; therefore, they will not be described in detail here.

[0033] A clamping mechanism is mounted on the product base 310 and is configured to clamp the automotive parts in the horizontal direction. The clamping mechanism includes two clamping assemblies 330, which are located on the front and rear sides of the product base 310, respectively, and the two clamping assemblies 330 can cooperate with each other to clamp the automotive parts.

[0034] Specifically, such as Figure 5As shown, the clamping assembly 330 includes a clamping block 331, a set screw 333, and a connecting block 334. The connecting block 334 is fixedly connected to the product base 310, such as by bolts. The clamping block 331 and the connecting block 334 are slidably connected in the front-back direction, such as by a slide rail groove fit structure, an optical axis guide sleeve combination, or a guide rail slider pair. The set screw 333 is provided on the connecting block 334 and is connected to the clamping block 331. The set screw 333 is configured to tighten the clamping block 331 so that the clamping block 331 abuts against the automotive part product in the front-back direction.

[0035] In one specific embodiment, the set screw 333 extends in the front-rear direction and is rotatably connected to the connecting block 334, allowing the set screw 333 to rotate relative to the connecting block 334 around its own central axis. One end of the set screw 333 has a rotating part, which can be configured as a handle. The other end of the set screw 333 has a threaded part, and the clamping block 331 has a threaded hole, with the threaded part and the threaded hole fitting together. It can be understood that by rotating the set screw 333, the length of the threaded part of the set screw 333 extending into the threaded hole of the clamping block 331 is adjusted, thereby adjusting the position of the clamping block 331 relative to the connecting block 334 in the front-rear direction. This allows the two clamping blocks 331 to move closer to each other in the front-rear direction, thus tightly clamping the automotive component.

[0036] Furthermore, an adjusting block 332 is connected to the bottom of the clamping block 331. The lower surface of the adjusting block 332 has a groove. The connecting block 334 has a guide rail extending in the front-to-back direction, which engages with the groove. A mounting block 335 is connected to the bottom of the connecting block 334 and is fixedly connected to the product base 310. The adjusting block 332 has two elongated holes extending in the front-to-back direction, which are also continuous in the vertical direction. The connecting block 334 has mounting screw holes. Screws pass through the elongated holes and are threaded into the mounting screw holes to enhance the connection between the adjusting block 332 and the connecting block 334, thereby strengthening the stability of the clamping block 331 and allowing the two clamping blocks 331 to more stably clamp the automotive parts.

[0037] Of course, it is not excluded that in other embodiments, the set screw 333 and the connecting block 334 are connected by a threaded structure, and the end of the set screw 333 can abut against the clamping block 331. By rotating the set screw 333, the front and rear positions of the set screw 333 relative to the connecting block 334 are adjusted, so that each clamping block 331 is tightly abutted against the automotive part under the tightening action of the set screw 333, thereby firmly combining the automotive part with the product positioning mechanism 300.

[0038] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the product base 310 includes a connecting plate 311 and a guide base 360. The lower surface of the connecting plate 311 is a positioning surface. The connecting plate 311 has a through hole 312. Furthermore, the positioning pin 340, the magnetic attraction mechanism 320, and the clamping mechanism are all located on the connecting plate 311. The upper end of the positioning pin 340 is fixedly connected to the lower surface of the connecting plate 311. The positioning pin 340 and the lower surface of the connecting plate 311 can together form a positioning structure. The magnetic attraction mechanism 320 is a magnetic base. The connecting plate 311 is positioned on both the left and right sides. A notch 313 allows the magnetic surface of the magnetic base to pass through, making the magnetic surface flush with the positioning surface. This causes the automotive part to simultaneously adhere to both the positioning surface and the magnetic surface, allowing the magnetic attraction mechanism 320 and the connecting plate 311 to form a pre-fixed structure. Mounting plates with openings are located on the front and rear sides of the connecting plate 311. These openings allow the clamping block 331 in the clamping mechanism to pass through in the front-rear direction. The mounting block 335 in the clamping mechanism is fixed to the mounting plate with bolts. Through the connecting plate 311, the positioning pin 340, the magnetic attraction mechanism 320, and the clamping mechanism, the product positioning mechanism 300 can be positioned and clamped on the automotive part.

[0039] The guide base 360 ​​includes multiple guide plates arranged around the through holes 312 on the connecting plate 311. The guide plates are detachably connected to the connecting plate 311 via screws. Each guide plate has a positioning guide surface 363. The positioning part 220 is configured to move vertically downward relative to the guide base 360 ​​and fit against each positioning guide surface 363. It is understood that the guide base 360 ​​is connected to the connecting plate 311, and the laser engraving device 100 is connected to the device base 200. The device base 200 contacts both the guide base 360 ​​and the connecting plate 311, forming a stable structure and facilitating easy assembly and disassembly of the device base 200 and the laser engraving device 100. The guide base 360 ​​can quickly match the laser engraving device 100 with the product positioning mechanism 300.

[0040] In this embodiment, the guide plates located on the left and right sides of the connecting plate 311 are designated as first guide plates 361. The first guide plates 361 are inverted T-shaped when viewed from the left and right direction. The two opposing surfaces of the two first guide plates 361 are positioning guide surfaces 363. The guide plates located on the front and rear sides of the connecting plate 311 are designated as second guide plates 362. The second guide plates 362 are U-shaped when viewed from the front and rear direction. The two opposing surfaces of the two second guide plates 362 are also positioning guide surfaces 363. The four positioning guide surfaces 363 together form a positioning cavity, which is connected to the through hole 312.

[0041] Understandably, when the equipment base 200 moves downward and extends into the positioning cavity, the second and third positioning surfaces of the positioning part 220 of the equipment base 200 will fit against the corresponding positioning guide surface 363, and the first positioning surface of the positioning part 220 of the equipment base 200 will fit against the upper surface of the connecting plate 311. Simultaneously, the through hole 312, the positioning cavity, and the channel 230 are connected. Therefore, the laser beam emitted by the laser marking equipment 100 can irradiate downwards onto the surface of the automotive part to be marked, thus performing the marking work. This design enables the positioning and docking of the equipment base 200 and the product positioning mechanism 300, thereby achieving a matching setup between the laser marking equipment 100 and the automotive part to be marked. By replacing different product positioning mechanisms 300, the automotive parts to be marked can be quickly switched, and the product positioning mechanism 300 can be accurately docked with the equipment base 200 to achieve accurate positioning of the laser marking equipment 100 before laser marking work on different automotive parts.

[0042] Furthermore, such as Figure 3 and Figure 4 As shown, the upper part of the connecting plate 311 is provided with an inclined portion 314, and the through hole 312 extends upward through the upper surface of the inclined portion 314. The upper surface of the inclined portion 314 is an inclined surface 315. In this embodiment, the inclined portion 314 and the connecting plate 311 are integrally formed, and the inclined surface 315 is inclined upward from front to back. The lower part of the guide base 360 ​​is fitted with the inclined surface 315, and the lower part of the guide base 360 ​​is detachably connected to the inclined portion 314. It can be understood that different automotive parts products will have corresponding product positioning mechanisms 300. After the automotive parts products are positioned and fixed on the corresponding product positioning mechanisms 300, the angle of the surface to be marked on the automotive parts products relative to the guide base 360 ​​is different. Therefore, the angle of the inclined surface 315 of the inclined portion 314 on different product positioning mechanisms 300 is different. By setting the inclined part 314, the guide base 360 ​​is fixedly installed on the inclined part 314 to adjust the angle of the laser beam of the laser marking equipment 100 relative to the surface to be marked of the automotive parts, so as to ensure that the laser beam is perpendicular to the surface to be marked.

[0043] In addition, such as Figure 1 As shown, a handle 350 is provided on the product base 310 to facilitate the handling of the product positioning mechanism 300.

[0044] When using the assembly fixture based on the laser marking equipment provided in the first aspect embodiment of the present invention, after the laser marking equipment 100 is installed on the equipment base 200, different automotive parts are installed on different product positioning mechanisms 300. Specifically, the positioning pins 340 are first inserted into the automotive parts to position them on the product base 310. Then, the magnetic attraction mechanism 320 applies an upward magnetic attraction to the automotive parts, pre-fixing them on the product base 310. Next, the clamping mechanism applies an effective clamping action on the horizontal plane to ensure that the automotive parts are stable relative to the product base 310. Then, the guide part is adapted to the positioning part 220 on the equipment base 200 to complete the positioning and matching of the laser marking equipment 100 relative to the automotive parts, facilitating the subsequent starting of the laser marking equipment 100 to perform marking operations on the automotive parts.

[0045] Therefore, when laser-engraving different automotive parts, the automotive parts to be engraved can be quickly switched by changing different product positioning mechanisms 300, and the product positioning mechanism 300 can be positioned and docked with the equipment base 200 to quickly assemble and position the laser engraving equipment 100 with different automotive parts, thereby reducing the number of laser engraving equipment 100 required and reducing equipment procurement and maintenance costs.

[0046] The first aspect of this invention addresses the problem of the inability to quickly change between different products during the existing laser marking process for automotive parts. It provides an assembly fixture based on a laser marking device that allows for rapid switching of marking products through simple operation. This enables quick assembly and positioning of the laser marking device 100 with different automotive parts during marking, significantly improving the utilization rate of the laser marking device 100. Furthermore, it saves on the increased costs associated with maintaining a large number of laser marking devices 100, greatly expanding the application range of the laser marking device 100. This effectively solves the problems of existing laser marking fixtures that cannot change marking products or require time-consuming and laborious adjustments.

[0047] like Figures 1 to 5As shown, the laser marking system according to a second aspect embodiment of the present invention includes a laser marking device 100 and an assembly fixture based on the laser marking device as described in the first aspect embodiment. The laser marking device 100 is fixedly connected to the mounting part 210. It is understood that after the laser marking device 100 is fixedly connected to the equipment base 200 of the assembly fixture, different automotive parts are fixedly connected to their corresponding product positioning mechanisms 300, and then the product positioning mechanisms 300 are docked with the equipment base 200. This enables the laser marking device 100 to quickly match and accurately position itself with different automotive parts, solving the problem of increased procurement quantity of laser marking devices 100 due to the increased number of automotive parts to be marked, and reducing equipment costs.
