Description

Technical Field

[0001] This utility model relates to the field of thin plate engraving technology, specifically a thin plate engraving device. Background Technology

[0002] Thin-plate engraving typically employs two processes: laser or thermoforming. Laser engraving uses a high-speed galvanometer to scan and focus a beam of light, instantly vaporizing or oxidizing the surface layer of a metal or PCB thin plate to form clear QR codes, characters, or patterns. It has a small heat-affected zone and no contact stress, making it suitable for small batches and variable data. Thermoforming, on the other hand, uses a heated mold to press characters or patterns onto the surface of the thin plate. It achieves permanent markings with high adhesion and high contrast through temperature and pressure, resulting in high efficiency and low cost, making it suitable for large-volume, uniform products.

[0003] For example, the existing invention patent CN102815157A proposes an engraving device. This invention uses a PLC to control a solenoid valve to drive a cylinder, which drives an engraving fixture with a built-in heating device to move downwards and align with the product fixing mold seat on the base to apply pressure, thereby realizing hot pressing engraving on the product positioned on the base.

[0004] As described above, since no fixing structure for the product is provided on the base, warping may occur due to the product's structure during engraving (such as for thin sheet products). In addition, the engraving position is not the same for each product. Due to the fixed engraving position, there are problems such as poor engraving effect and low device compatibility. Utility Model Content

Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Please see Figure 1-4 The thin plate engraving device proposed in this application includes a worktable 1, a fixed structure 2, an engraving structure 3 and a driving structure 4.

[0045] like Figure 1-2 , Figure 4As shown, the workbench 1 includes a support base 11 and a support frame 12. The support frame 12 is arranged in an inverted U-shape on the support base 11. The fixing structure 2 is located inside the top of the support frame 12 and is used to fix the thin plate on the support base 11. The engraving structure 3 includes a mounting plate 31 and an engraving component 32. The mounting plate 31 is horizontally arranged inside the support frame 12 and is offset from the fixing structure 2. Multiple sets of mounting grooves 301 are evenly opened at the bottom of the mounting plate 31. The engraving component 32 is detachably arranged in one set of mounting grooves 301 and is used to select and install in the corresponding set of mounting grooves 301 according to the engraving position. The driving structure 4 is located on the support base 11 and is detachably connected to the top of the mounting plate 31 and is used to drive the engraving component 32 to perform engraving work.

[0046] Specifically, the support base 11 and the inverted U-shaped support frame 12 form a rigid gantry frame. The fixing structure 2 first firmly presses the thin plate onto the support base 11 from top to bottom, avoiding warping defects caused by lack of fixation. Subsequently, the operator only needs to insert the engraving component 32 into the required set of mounting slots 301 to quickly complete the switching of the engraving position. The drive structure 4 then drives the mounting plate 31 to descend vertically to complete the engraving. Here, the engraving component 32 and the mounting slot 301 can adopt a dovetail or T-shaped quick-release structure, realizing that one set of equipment can adapt to multiple engraving patterns and multiple plate sizes, significantly improving its adaptability. The engraving component 32 here can be a conventional component in existing technologies such as hot pressing engraving or laser engraving.

[0047] In some embodiments, such as Figure 4 As shown, the worktable 1 also includes a positioning seat 13 and an engraving seat 14. The positioning seat 13 is disposed on the support seat 11 and is correspondingly disposed with the fixing structure 2, and is used to clamp the thin plate in conjunction with the fixing structure 2. The engraving seat 14 is disposed on the support seat 11 and is correspondingly disposed with the engraving part 32. The top surface of the engraving seat 14 is flush with the top surface of the positioning seat 13, and is used to provide a support base for the engraving part 32.

[0048] Specifically, the upper surfaces of the positioning seat 13 and the engraving seat 14 form a coplanar double support. After the thin plate is pressed onto the positioning seat 13 by the fixing structure 2, the area to be engraved falls exactly above the engraving seat 14, obtaining rigid back support from bottom to top. This avoids the phenomenon of uneven imprint depth caused by local concavity of the thin plate during the engraving process, thereby ensuring uniform transmission of hot pressing or laser energy, resulting in neat pattern edges and high contrast.

[0049] In some embodiments, such as Figure 4As shown, the positioning base 13 includes a support plate 131 and positioning posts 132; the support plate 131 is horizontally disposed on the support base 11, and its top surface is flush with the top surface of the engraving base 14; the positioning posts 132 include two sets, which are symmetrically disposed at both ends of the top of the support plate 131 for positioning the two sides of the thin plate; the corresponding fixing structure 2 includes a first cylinder 21 and a clamping plate 22, wherein the first cylinder 21 is disposed at the top of the support frame 12 and is disposed perpendicular to the top of the support frame 12; the clamping plate 22 is horizontally disposed at the bottom of the first cylinder 21 and is disposed corresponding to the support plate 131, and the driving end of the first cylinder 21 is detachably connected to the top of the clamping plate 22.

[0050] Specifically, in actual assembly, the top surface of the support plate 131 and the top of the engraving seat 14 are located on the same reference plane. After the thin plate is fed in by the pushing structure 5, its two sides are first positioned by the positioning pins 132 on the positioning seat 13, and at the same time, the entire lower surface is attached to the support plate 131 and the engraving seat 14. Subsequently, the first cylinder 21 moves downward, and the clamping plate 22 and the support plate 131 clamp the top and bottom sides of the thin plate, so that the thin plate attached to one end of the engraving seat 14 is flat and attached to the engraving seat 14, ensuring that the engraving energy is completely transferred to the thin plate and is not absorbed by elastic deformation; at the same time, the detachable connection facilitates later maintenance and replacement.

[0051] In some embodiments, such as Figure 4 As shown, the engraving base 14 includes a support platform 141 and a support block 142. The support platform 141 is disposed on the support base 11 and is correspondingly disposed with the mounting plate 31. The top surface of the support platform 141 is provided with a placement groove 101 corresponding to each set of mounting grooves 301. The support block 142 is detachably disposed in the corresponding placement groove 101 along with the engraving part 32. The top surface of the support block 142 is flush with the top surface of the positioning base 13.

[0052] Specifically, when it is necessary to change the engraved pattern or plate width, the operator only needs to simultaneously pull out the original support block 142 and insert it into the new support block 142 corresponding to the engraving part 32 inserted into the mounting slot 301. The entire replacement process is convenient and quick. The support block 142 adopts a modular design with the same width as the engraving part 32, which not only ensures the convenience and speed of the replacement process, but also avoids the material waste caused by large-area support, thus achieving the beneficial effect of "local adjustability and global coplanarity".

[0053] In some embodiments, such as Figure 1-2 , Figure 4As shown, the drive structure 4 includes a second cylinder 41, a drive plate 42, guide rods 43, and limiting blocks 44. The second cylinder 41 is located on the top of the support frame 12, and its drive end slides downward through the top of the support frame 12 and is set perpendicular to the mounting plate 31. The drive plate 42 is located on the top of the mounting plate 31 and is detachably connected to it. The top of the drive plate 42 is fixedly connected to the drive end of the second cylinder 41. There are four guide rods 43, which are respectively set perpendicularly on the top periphery of the drive plate 42. The top of the guide rods 43 passes upward through the top of the support frame 12 and is slidably connected to it. There are four limiting blocks 44, which are respectively set on the top of the four guide rods 43 to prevent the guide rods 43 from falling out of the support frame 12.

[0054] Specifically, the second cylinder 41 directly drives the mounting plate 31 to move vertically up and down via the drive plate 42, eliminating the intermediate transmission link, resulting in a simple structure and rapid response; the four guide rods 43 form a sliding fit with the support frame 12, ensuring that the mounting plate 31 always maintains vertical movement and avoids lateral swaying; the limit block 44 forms a mechanical stop at the top of the guide rods 43 to prevent the drive plate 42 and the mounting plate 31 from moving excessively upward and detaching, ensuring the safe operation of the device; at the same time, the detachable connection of the mounting plate 31 facilitates later maintenance and replacement.

[0055] In some embodiments, such as Figure 1-2 As shown, a thin plate engraving device further includes a pushing structure 5, which includes a support plate 51 and a pushing cylinder 52. The support plate 51 is horizontally disposed on the support base 11 and located on one side of the fixing structure 2. The distance from the top of the support plate 51 to the top surface of the support base 11 is the same as the distance from the top surface of the positioning seat 13 to the top surface of the support base 11. The pushing cylinder 52 is disposed on the support base 11 and located at the end away from the fixing structure 2, and is used to push the thin plate to move towards the support base 11. The support plate 51 includes a plate body 511 and ball bearings 512. The plate body 511 is horizontally disposed on the support base 11. The ball bearings 512 include a plurality of balls, which are uniformly rotated on the top surface of the plate body 511. The distance from the top of the ball bearings 512 to the top surface of the support base 11 is the same as the distance from the top surface of the positioning seat 13 to the top surface of the support base 11.

[0056] Specifically, the push cylinder 52 pushes the thin plate from the support plate 51 to the working area of ​​the positioning seat 13 and the fixed structure 2; since the ball bearing 512 is rotatably mounted on the plate 511, there is rolling contact between the thin plate and the ball bearing 512, resulting in low frictional resistance, smooth movement, and less risk of scratching the surface; the top of the ball bearing 512 is flush with the top surface of the positioning seat 13, keeping the thin plate on the same horizontal plane during movement and achieving a smooth transition; the whole process realizes unmanned continuous feeding, significantly improving batch production efficiency and reducing manual placement errors, thereby improving feeding efficiency and positioning accuracy.
