Description
Technical Field
[0001] This utility model relates to the field of automotive parts production equipment, and in particular to a laser engraving fixing table for automotive trim strips. Background Technology
[0002] With the rapid development of the automotive industry, consumers are increasingly demanding more aesthetically pleasing and personalized car interiors. As a key component of the interior, the precision of laser engraving of the surface markings, patterns, or textures of automotive trim directly affects the product's market competitiveness.
[0003] The existing publication number CN220196655U discloses a laser engraving fixing stage for automotive trim strips, including a worktable and a fixing frame, and further including a limiting module for placing the fixing frame at a predetermined position on the worktable; the fixing frame has a fixing groove for placing the automotive trim strip; the edge of the fixing groove is adapted to the shape of the outer frame of the automotive trim strip; the fixing frame has a first limiting block for keeping the automotive trim strip horizontally placed; a plurality of second limiting blocks are arranged inside the fixing groove; the second limiting blocks and the fixing groove cooperate to limit the horizontal movement of the automotive trim strip. This laser engraving fixing stage can achieve stable fixing and precise positioning of the automotive trim strip, and improves the precision of the fixing frame on the worktable. For precise positioning, the worktable is equipped with a boss, on which the fixing bracket is placed. This boss restricts the vertical movement of the fixing bracket. Then, through the fixing of the limiting module, the fixing bracket is precisely positioned on the worktable. The limiting module is preferably a quick-release pin, which can be quickly inserted and removed, thus enabling quick assembly and disassembly of the fixing bracket. Depending on the actual needs, positioning columns can also be used. Moreover, the laser engraving machine can hold multiple fixing brackets. When the fixing bracket needs to be moved to the predetermined position, the operator can directly push the fixing bracket to slide on the boss. After reaching the predetermined position, the limiting module is used to fix it, reducing the workload of the operator and improving work efficiency. It was found that the above-mentioned device still has shortcomings in use. First, although the device can stabilize and fix the car trim strip to a certain extent, it relies on quick-release pins or positioning posts as limiting modules. On the one hand, when multiple fixing brackets are placed, the limiting modules need to be frequently pulled out and pulled back to adjust the position of the fixing brackets. This operation is not only time-consuming and laborious, but the repeated friction between the pins and positioning holes caused by frequent pulling out and pulling can easily lead to wear, which in turn leads to a decrease in positioning accuracy. That is, when the wear is high, if the trim strip continues to be laser-engraved, the fixing bracket is prone to shaking and loosening, affecting the processing stability. On the other hand, in the scenario where multiple fixing brackets are arranged side by side, it is difficult to ensure the relative positional accuracy of each fixing bracket when manually pushing the fixing brackets to the predetermined position. Accumulated errors can easily lead to misalignment or overlap of the laser-engraved pattern on the trim strip. Furthermore, the sliding distance cannot be quantified in real time, and the reliance on manual experience for adjustment further aggravates the positioning error and causes inconvenience in actual use.
[0004] Therefore, it is necessary to provide a new laser engraving mounting platform for automotive trim to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please refer to the following: Figures 1 to 8 ,in, Figure 1 A schematic diagram of the overall structure of the laser engraving fixing platform for automotive trim provided by this utility model; Figure 2 This is a schematic diagram of the structure of the first chute; Figure 3 for Figure 2 Enlarged view of point A in the middle; Figure 4 This is a schematic diagram of the through-slot structure; Figure 5 This is a structural diagram of the component being installed; Figure 6 A schematic diagram of the laser engraving fixing platform for the automotive trim provided by this utility model; Figure 7 This is a schematic diagram of the turntable structure; Figure 8 This is a breakdown diagram of the turntable section.
[0018] In some embodiments, such as Figures 1 to 8As shown, the device includes an operating table 1 and a fixed frame 2. Two parallel slide rails 11 are fixed to the top of the operating table 1. The bottom of the fixed frame 2 slides on the top of the two slide rails 11. The fixed frame 2 slides on the surface of the slide rails 11 via a sliding plate 12. The bottom of the fixed frame 2 can be fixed by direct welding to the top of the sliding plate 12 or by fixing a card block at the bottom of the fixed frame 2 and inserting it into the end slot of the sliding plate 12. The surface of the slide rails 11 is engraved with scales 111 for detecting the sliding distance of the fixed frame 2. A mounting component for limiting the movement distance of the fixed frame 2 is slidably provided on one side of the slide rails 11. One end of the mounting component passes through the surface of the slide rails 11 and the sliding plate 12 in sequence and is inserted into the bottom of the fixed frame 2. The surface of the mounting component is also provided with a limiting component for adjusting the insertion depth of the mounting component. Specifically, by engraving a scale 111 on the surface of the slide rail 11, the sliding distance of the fixed frame 2 can be quantitatively measured in real time. Operators can accurately read the displacement value, avoiding errors caused by manual experience adjustment, meeting the high-precision processing requirements of automotive interiors. Operators can directly adjust the position of the fixed frame 2 according to the scale 111 without repeated trial and error, shortening the single positioning time and significantly improving the efficiency and consistency of collaborative processing of multiple fixed frames 2. Furthermore, by setting up a mounting component that passes through the slide rail 11 and the slide plate 12 and is fixed to the bottom of the fixed frame 2, multiple sets of limiters are used instead of the traditional single set or a small number of pins that are repeatedly pulled out. This reduces the problem of the fixed frame 2 shaking or loosening due to friction and wear between the limit module 22 and the positioning hole. In other words, the use of multiple sets of mounting components for limiters makes the fixed frame 2 more stable after limiters are set, which significantly improves processing stability and equipment life. Moreover, the mounting component is used to simultaneously perform mounting limiters and pull out pins. In scenarios where multiple fixed frames 2 are arranged side by side, operators do not need to repeatedly bend over and pull out pins, which reduces the time for a single positioning and significantly reduces labor intensity.
[0019] In some embodiments, reference is made to Figures 1 to 7 As shown, the bottom walls of both slide rails 11 are provided with a slide groove 112. The bottom of the slide groove 112 passes through the bottom wall of the slide rail 11 and extends into the operating table 1. The inner walls of both slide rails 11 are provided with a limiting groove 113. One side of the component is slidable on the inner wall of the limiting groove 113. The top of the slide rail 11 is provided with a plurality of arrayed insertion holes 114. The top of the slide plate 12 is provided with a plurality of arrayed insertion holes 121. The diameter of the insertion holes 121 matches that of the insertion holes 114. One end of the component is inserted through the insertion holes 114 and the insertion holes 121 in sequence and is inserted into the bottom of the fixing frame 2. Preferably, the bottom of the fixing frame 2 is provided with a plurality of arrayed mounting grooves to facilitate the insertion of one end of the component. The mounting assembly includes a mounting box 4. One end of each of the two slide rails 11 is fixed to one side of the mounting box 4. A rotating shaft 421 is fixed to the inner wall of the mounting box 4. A long gear 42 is fixed to the surface of the rotating shaft 421, and a long rack 43 meshes with the surface of the long gear 42. A guide groove 13 is provided at the bottom of the mounting box 4. The bottom of the long rack 43 slides on the inner wall of the guide groove 13. Two sliders 431 are fixed to both sides of the long rack 43, allowing the long rack 43 to slide on the inner wall of the guide groove 13 via the two sliders 431. 4. A through groove 41 is provided on one side near the two slide rails 11. The mounting box 4 is connected to the interior of the two slide rails 11 through the two through grooves 41 respectively. Two sliding components are fixed on the side of the long rack 43 away from the long gear 42. One end of the two sliding components passes through the through groove 41 and extends into the two slide rails 11. One end of the two sliding components slides on the inner sidewall of the two limiting grooves 113 respectively. The top of the two sliding components passes through the first insertion hole 114 and the second insertion hole 121 in sequence and is inserted into the bottom of the fixing frame 2. Both sliding components include push plates 3. One end of each push plate 3 passes through the through groove 41 and extends into the two slide rails 11. The bottom of each push plate 3 slides on the inner wall of the slide groove 112. Both sides of each push plate 3 are fixed with sliders 31. One end of each push plate 3 slides on the inner wall of the two limiting grooves 113 through sliders 31. The top of each push plate 3 is fixed with multiple arrayed insert rods 32. One end of each insert rod 32 passes through the insertion hole 114 and the insertion hole 21 in sequence and is inserted into the mounting groove at the bottom of the fixing frame 2. The outer side of the mounting box 4 has a circular array of three sockets 44. One end of the rotating shaft 421 passes through the surface of the mounting box 4 and is fixed to the turntable 5. The surface of the turntable 5 is fixed with a rotating rod 51. The surface of the turntable 5 has a sliding groove 52, which is directly opposite the socket 44. One end of the limiting component slides on the surface of the sliding groove 52. The cooperation between the limiting component and the socket 44 can effectively lock the position of the turntable 5, preventing the turntable 5 from rotating due to accidental contact during use, which would cause the horizontal movement of the fixing bracket 2 to shake or move, resulting in the overlap of the car trim pattern during laser engraving.
[0020] Specifically, during use, the operator rotates the turntable 5 counterclockwise using the rotating rod 51, causing the rotating shaft 421 and the long gear 42 to rotate. The long gear 42 drives the long rack 43 to move upward in a straight line along the guide groove 13. The long rack 43 drives the two push plates 3 to slide upward along the through groove 41 inside the slide rail 11. The slider 31 at the bottom of the push plate 3 slides in the limiting groove 113, causing the push plate 3 to move upward in a straight line. At this time, the insertion rod 32 at the top of the push plate 3 passes through the insertion hole 114 and the insertion hole 21 in sequence and is inserted into the bottom of the fixed frame 2, realizing the mechanical limiting and fixing of the fixed frame 2. When the insertion rod 32 is fully inserted into place, the operator pushes the limiting component, causing one end to slide along the sliding groove 2 52 and insert into the insertion hole 3 44, locking the position of the turntable 5 to prevent it from rotating accidentally and ensuring the stability of the fixed frame 2. When it is necessary to release the limit, the operator first pushes the limit component so that one end is pulled out of the insertion hole 44, releasing the lock on the turntable 5. The turntable 5 is rotated clockwise by the rotating rod 51, which drives the long gear 42 to rotate in the opposite direction, driving the long rack 43 to move in the opposite direction. The long rack 43 drives the two push plates 3 to move downward along the limit groove 113. The insertion rod 32 is pulled out from the bottom of the fixed frame 2, the slide plate 12, and the slide rail 11 in sequence, releasing the limit of the fixed frame 2. At this time, the slide plate 12 and the fixed frame 2 can be moved freely to the required position. The limit and fixation are performed again by inserting the component, and the position of the turntable 5 is locked again.
[0021] In some embodiments, reference is made to Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the limiting assembly includes a limiting rod 53, with multiple sliders 531 fixed to the outer ring of the limiting rod 53. A limiting groove 521 is formed on the inner side wall of the sliding groove 52. One end of the limiting rod 53 is inserted into the sliding groove 52, and the limiting rod 53 slides in the limiting groove 521 through the multiple sliders 531, thereby realizing the radial movement and guidance of the limiting rod 53. Locking process: When the turntable 5 rotates to the required position, such as when the insertion rod 32 is fully inserted into the bottom of the fixing frame 2, the operator pushes the limiting rod 53, so that it slides along the slide groove 2 52 towards the mounting box 4. The limiting rod 53 slides in the limiting groove 2 521 through the slider 3 531. One end of the limiting rod 53 is inserted into the insertion hole 3 44 on the outside of the mounting box 4, thereby locking the turntable 5 and preventing it from rotating accidentally. Unlocking process: When it is necessary to rotate the turntable 5 to adjust the position of the mounting component, the operator pulls the limit rod 53, causing it to slide along the slide groove 2 52 away from the mounting box 4. The limit rod 53 is pulled out from the insertion hole 3 44, releasing the lock on the turntable 5, and the turntable 5 can rotate freely. Specifically, during use, the operator only needs to push or pull the limit rod 53 to lock and unlock the turntable 5 without complicated tools or operating steps, preventing the turntable 5 from rotating due to accidental contact or vibration.
[0022] In some embodiments, reference is made to Figure 1 As shown, the top of the fixing frame 2 is also fixed with a limiting block 1 21, a limiting module 22, a limiting block 23 and a limiting block 3 24 for limiting the car trim strip, and the limiting block 1 21, the limiting module 22, the limiting block 23 and the limiting block 3 24 are respectively located at relative positions on the top of the fixing frame 2. Specifically, the limiting blocks 21, 23, and 24 in this device all adopt the limiting blocks 1, 2, and 3 as disclosed in patent publication number CN220196655U. Their structure, materials, and the principle of limiting the trim strip are all existing technologies and will not be described here.
[0023] Furthermore, in this embodiment, the limiting module 22 adopts the limiting module in patent publication number CN220196655U in terms of structure and material, which is the prior art. There are multiple holes in the engraving area on the operating table 1 for use with the limiting module 22. The position of the holes and the size of the fixing frame 2 can be displayed in the software of the laser engraving machine. After the program of the laser engraving machine is programmed, the fixing frame 2 is placed in the preset position on the operating table 1 and fixed with the limiting module 22. Then the car trim strip is placed on the fixing frame 2 for engraving. The laser engraving machine is a commonly used laser engraving machine on the market. The specific working principle is not described in detail here. The fixing method of the limiting module 22 in this device is different from that in CN220196655U. The bottom of the limiting module 22 in this device does not need to limit the slide rail 11, but only needs to fix the trim strip. That is, the bottom of the limiting module 22 does not need to limit the fixing frame 2 that slides on the surface of the slide rail 11.
[0024] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
