Abstract
Description
Technical Field
[0001] This application relates to the field of fixture technology, and more specifically, to a fixture for QR code laser engraving. Background Technology
[0002] To add anti-counterfeiting and traceability information to products, QR code markings are laser-engraved onto them using a QR code laser printer. Specifically, when the QR code laser printer is working, an internal laser generator first converts electrical energy into a high-energy laser beam. After the optical system focuses and increases the energy density, the beam is directed at the surface of the product. The surface material absorbs the energy, causing it to melt and vaporize. Simultaneously, the computer control system precisely controls the laser beam's path and intensity, scanning and processing according to a preset QR code pattern or encoded information. After the laser stops, the processed area on the product surface cools and solidifies, leaving a clear, accurate, durable, and tamper-proof QR code mark.
[0003] Existing QR code laser engraving machines require fixtures to position and fix workpieces during processing. However, for flat metal workpieces that require double-sided laser engraving, existing fixtures cannot be flipped, resulting in manual disassembly, flipping, and reassembly after each single-sided laser engraving. This cumbersome operation significantly extends the processing cycle, reduces output per unit time, and increases time costs. Summary of the Invention

[0026] like Figure 1-3 As shown, this application provides a fixture for QR code laser engraving, including a base 1, a support seat 2 slidably disposed on the base 1, a drive cylinder 3 for driving the support seat 2 to move on the base 1, a support frame 4 rotatably disposed on the support seat 2, a flip motor 5 for driving the support frame 4 to flip on the support seat 2, and a clamping assembly 6 on the support frame 4. The clamping assembly 6 can clamp the workpiece onto the support frame 4. The drive cylinder 3 drives the support seat 2 on the base 1 to move, so that when performing QR code laser processing on workpieces of different sizes, the horizontal position of the workpiece can be precisely adjusted according to specific needs. The clamping assembly 6 can clamp the workpiece onto the support frame 4. The support seat 2, together with the flip motor 5, drives the support frame 4 to flip, providing a seamless flipping solution for workpieces that need to be laser-engraved on both sides. This avoids the inefficiency caused by manual disassembly, flipping, and reassembly, resulting in a continuous processing flow, significantly shortening the overall operation time and improving production efficiency.
[0027] like Figure 1 and Figure 2 As shown, the support frame 4 consists of a U-shaped frame 41 and a rotating shaft 42. The flipping motor 5 is fixed on the support base 2, and the rotating shaft 42 is rotatably mounted on the support base 2. One end of the rotating shaft 42 is fixedly connected to the frame 41, and the other end of the rotating shaft 42 is connected to the output shaft of the flipping motor 5. The U-shaped frame 41 is used as the main part to support the workpiece. Its shape naturally has good embracing support characteristics. When it is necessary to perform double-sided laser engraving on the workpiece and perform the flipping action, the flipping motor 5 drives the rotating shaft 42 to rotate the support frame 4 180°.
[0028] like Figure 1As shown, the bottom of the U-shaped frame 41 is provided with an inwardly protruding support part 411. When placing the workpiece, the inwardly protruding support part 411 can form a contact shape with a higher degree of fit with the bottom of the workpiece, and the support part 411 can provide stable support for the bottom of the workpiece.
[0029] like Figure 1 and Figure 2 As shown, the clamping assembly 6 includes a clamping cylinder 61, a clamping block 62, a first guide post 63, and a second guide post 64. The clamping block 62 is located at the opening of the U-shaped frame 41. The clamping cylinder 61 is fixedly mounted on one side of the U-shaped frame 41, and the telescopic rod of the clamping cylinder 61 is fixedly connected to the clamping block 62. One end of the first guide post 63 and one end of the second guide post 64 are both fixedly connected to the side of the clamping block 62 near the U-shaped frame 41. One arm of the U-shaped frame 41 has a first guide hole 412 that matches the first guide post 63, and the other arm of the U-shaped frame 41 has a second guide hole 413 that matches the second guide post 64. The first guide post 63 is inserted into the first guide hole 412, and the second guide post 64 is inserted into the second guide hole. Within 413, the clamping cylinder 61 serves as the power drive source, precisely controlling the clamping force and displacement of the clamping block 62 according to instructions (issued by the control system to the clamping cylinder 61). In QR code laser processing, whether it's a thin metal sheet or a slightly harder metal plate, the appropriate clamping force can be applied as needed, effectively preventing the workpiece from shifting due to laser impact or equipment vibration during laser processing due to excessively loose clamping, or from being damaged or deformed due to excessively tight clamping. This ensures accurate QR code laser positioning and clear patterns. The first guide post 63 and the second guide post 64, in conjunction with the corresponding first guide hole 412 and second guide hole 413, construct a stable guiding path for the movement of the clamping block 62. When the clamping cylinder 61 drives the clamping block 62 to open and close, the guide post slides smoothly within the guide hole, strictly limiting the clamping block 62's degrees of freedom other than the opening and closing direction, preventing any instability such as offset or wobbling.
[0030] like Figure 1 and Figure 2 As shown, the base 1 is provided with a guide groove 11, the lower part of the support 2 is adapted to the guide groove 11, and the lower part of the support 2 is slidably connected to the guide groove 11. The drive cylinder 3 is fixed on the base 1, and the telescopic end of the drive cylinder 3 is fixedly connected to the support 2. When the drive cylinder 3 drives the support 2 to move to adjust the position of the workpiece, the guide groove 11 strictly restricts the displacement of the support 2 in the predetermined straight direction to avoid deviations such as left-right or up-down offsets, ensuring that the workpiece can be accurately positioned to the best laser position, greatly improving the accuracy of the QR code laser position and ensuring smooth subsequent scanning and recognition.
[0031] like Figure 1 and Figure 2As shown, a first rubber block 7 is fixed on the side of the clamping block 62 near the U-shaped frame 41, and a second rubber block 8 is fixed on the inner side of the U-shaped frame 41 opposite to the clamping block 62. During the clamping process, when the metal clamping block 62 and the U-shaped frame 41 directly contact the workpiece, the workpiece surface is easily damaged by hard-on-hard squeezing, resulting in scratches, indentations, and other damage.
[0032] like Figure 1 and Figure 2 As shown, a receiving box 9 with an open top is provided between the base 1 and the support frame 4. The receiving box 9 is placed on the base 1. During the QR code laser process, a lot of waste will be generated, such as metal fragments ablated by the laser and tiny particles after the smoke condenses. The receiving box 9 is located below the working area and has an open top. When the support frame 4 is flipped, it can naturally receive various waste materials falling from above, effectively preventing waste materials from scattering on the working platform or workshop floor, greatly reducing the difficulty and time of manual waste cleaning, and improving the cleanliness and management convenience of the production site.
[0033] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
