Description

Technical Field

[0001] This utility model belongs to the technical field of laser marking devices, specifically relating to an automated marking and engraving device for marking steel templates. Background Technology

[0002] Steel formwork is commonly used in the pouring of concrete components (such as walls and columns) during construction. For formwork manufacturers and large construction companies, marking with laser marking machines is the foundation of efficient management. Through the coding system, thousands of formworks of different specifications and types can be classified, archived, and digitally managed.

[0003] Existing laser marking machines mainly use a worktable to support blanks, with a low-power laser beam emitted from a laser head above to mark the blanks. The laser head is moved by a motor-driven lead screw or a drag chain-type electric slide rail, so that the laser marks the preset graphics or text along a designated path.

[0004] In the laser engraving process, some manufacturers use a motor-driven rotating worktable to achieve double-sided loading. However, steel formwork used in the construction industry often has square, arc, or other shapes, which presents the following problems: 1. The double-sided structure of the worktable is mostly the same, making it difficult to fit blanks of different shapes. Different worktables need to be replaced, leaving the curved worktable idle and resulting in waste. This is mainly reflected in the difficulty of reducing the engraving cost of curved blanks.

[0005] 2. When the arc-shaped worktable rotates, it is difficult to lock the arc-shaped blanks of different sizes on it, causing the arc-shaped blanks to shift due to the rotation, which may reduce the engraving accuracy of the arc-shaped blanks. Utility Model Content

[0006] The purpose of this invention is to provide an automated marking and engraving device for steel template marking. It can switch between two working states to support square blanks and arc-shaped blanks respectively. During the rotation and engraving process of the arc-shaped blank, it can be locked to improve the engraving accuracy and reduce the engraving cost of the arc-shaped blank.

[0007] The specific technical solution adopted by this utility model is as follows: An automated marking and engraving device for steel formwork identification includes a cabinet and a laser engraving head, and further includes: A double-headed workbench is provided on the top surface of the cabinet, with a straight first head and an arc-shaped second head arranged opposite each other on the double-headed workbench; An arc-shaped groove and a strip-shaped hole are formed on the outer arc surface of the second head, and a wing bolt is provided on the strip-shaped hole; When the wing bolt is turned in the forward direction, it is used to lock the blank in the arc groove. When the wing bolt is turned in the reverse direction, it releases the locked state of the blank in the arc groove.

[0008] As an optional solution, the wing bolt is externally provided with a friction plate and a bent rod; The wing bolt is used to press the friction plate into contact with the opening of the strip hole when it is turned in the forward direction. Under the friction, the friction plate drives the bent rod to be suspended outside the strip hole, thereby supporting the blank in the arc groove.

[0009] As an optional solution, the top surface of the cabinet is provided with a mold changing port for the movement of the dual-head workbench; Both sides of the mold changing port are equipped with load-bearing rotating shafts that connect to the double-headed worktable.

[0010] As an optional solution, the cabinet is externally equipped with interconnected crossbeams and electric cable chain rails; The laser engraving head is mounted on the electric drag chain guide rail, and the laser engraving head is lower than the crossbeam.

[0011] As an alternative, the projection of the second head onto the first head is not less than two-thirds of the plane of the first head.

[0012] As an optional solution, a brake motor connected to the load-bearing shaft is installed inside the cabinet; The brake motor is used to drive the load-bearing shaft to rotate the double-headed worktable.

[0013] As an optional solution, one end of the wing bolt is threadedly connected to a support plate; The support plate is slidably installed inside the cabinet, and the width of the support plate is greater than the width of the strip hole.

[0014] The technical effects achieved by this utility model are as follows: This invention can switch between the first head and the second head to support square blanks and arc-shaped blanks respectively. There is no need to change the worktable, which makes it convenient for the dual-head worktable to be used continuously in the engraving process of blanks of various shapes. It can reduce the waste caused by some worktables being idle or even abandoned, and help reduce the engraving cost of arc-shaped blanks.

[0015] This invention is equipped with several adjustable butterfly bolts, friction plates and bent rods on each second head, which respectively abut against the two ends of the arc-shaped blank or against the rib plate of the arc-shaped blank, thereby achieving stable clamping of the arc-shaped blank and avoiding the displacement of the arc-shaped blank due to inertia caused by the rotation of the second head, which helps to improve the accuracy of the rotational engraving of the arc-shaped blank.

[0018] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0019] like Figures 1-5 As shown, an automated marking and engraving device for steel formwork includes a cabinet 1 and a laser marking head 5. During operation, the steel formwork can be placed on the top surface of the cabinet 1, and a low-power laser beam is emitted by the laser marking head 5 to achieve marking at a specified depth. Two parallel columns 2 are fixed to the top surface of the cabinet 1 by bolts, and a crossbeam 3 and an electric drag chain guide rail 4 are connected between the tops of the two columns 2 by bolts. The laser marking head 5 can be set on the electric drag chain guide rail 4, and the electric drag chain guide rail 4 is controlled by an industrial computer to realize the forward or backward movement of the laser marking head 5 along the X-axis. Since the laser marking head 5 is lower than the crossbeam 3, it can complete the marking along the programmed path at a position close to the steel formwork.

[0020] Among them, the electric drag chain guide 4 is generally driven by a servo motor coupling reducer to drive the ball screw, so as to move the slider along the X-axis and drive the laser engraving head 5 to move. The servo motor signal is connected to the industrial computer, and the distance of this displacement or stopping at a specified position can be controlled by the program.

[0021] As an optional embodiment, the laser engraving head 5 can translate the laser collimator by using a built-in miniature linear electric guide rail, which can move along the Y-axis to achieve a small-amplitude path change in the XY plane, making it convenient for the laser beam to engrave patterns or text.

[0022] Referring to the attached diagram, the laser generator 6 generally includes a carbon dioxide laser, a compressed air cooler, a Gaussian distribution lens, and an optical fiber. After the carbon dioxide laser emits a laser beam, the laser beam is transmitted using the Gaussian distribution lens and the optical fiber, and the compressed air cooler is used to cool the carbon dioxide laser.

[0023] In the processing of steel formwork, it is generally necessary to use laser beams to engrave identification codes on its exterior surface for quantitative management in subsequent use. Steel formwork is generally divided into square blanks and curved blanks. Curved blanks need to be engraved on the curved surface, which is more difficult to process.

[0024] See attached document Figure 1 , Figure 2 and Figure 3 To facilitate the processing of curved blanks, this embodiment also includes: The double-headed workbench 9, which is rotatably installed on the top surface of the cabinet 1, has a first head that is flat and a second head that is arc-shaped, which are arranged opposite each other on the hollow double-headed workbench 9. The first head can be used to carry square blanks and the second head can be used to carry arc-shaped blanks. The whole equipment can be used to accommodate steel templates of different shapes. An arc-shaped groove 11 and a strip hole 12 are provided on the outer arc surface of the second head. The arc-shaped blank can be placed in the arc-shaped groove 11 to limit the horizontal movement of the arc-shaped blank. Four wing bolts 13 are provided on the strip hole 12, and the four wing bolts 13 can slide along the strip hole 12 to reach different positions. When the wing bolt 13 is turned in the forward direction, it presses against the arc-shaped blank to lock the blank in the arc-shaped groove 11. When the wing bolt 13 is turned in the reverse direction, it releases the locking state of the blank in the arc-shaped groove 11. The position of the wing bolt 13 can be adjusted to lock arc-shaped blanks of different lengths.

[0025] Therefore, this embodiment can switch between the working state of the first head and the second head to support square blanks and arc-shaped blanks respectively, without the need to change the worktable. This makes it convenient for the dual-head worktable 9 to be continuously used in the engraving process of blanks of various shapes, which can reduce the waste caused by some worktables being idle or even abandoned, and help reduce the engraving cost of arc-shaped blanks.

[0026] See attached document Figure 1 and Figure 2 The top surface of the cabinet 1 is provided with a mold changing port 7 for the movement of the double-headed workbench 9. The hollow double-headed workbench 9 can be taken out and put in through the mold changing port 7, which facilitates maintenance and installation. Additionally, load-bearing rotating shafts 8 are bolted to both sides of the mold changing port 7 to connect the double-headed worktable 9. The double-headed worktable 9 is supported from both sides by the two load-bearing rotating shafts 8, which facilitates the stable suspension of the double-headed worktable 9.

[0027] See attached document Figure 2 , Figure 3 and Figure 5 In this embodiment, a brake motor 10 is installed inside the cabinet 1 by bolts. The output end of the brake motor 10 is connected to the load-bearing shaft 8 via a V-belt, and the brake motor 10 is connected to the industrial computer. Under the control of the preset program, the brake motor 10 is started to rotate the load-bearing shaft 8 a specified number of times, which drives the double-headed worktable 9 to rotate, so as to realize the alternating exposure of the first head and the second head. When the second head carries the arc-shaped blank, the second head can rotate the arc-shaped blank at a constant speed under the drive of the brake motor 10, so that the laser beam moves relative to the arc-shaped blank and engraves patterns or text.

[0028] See attached document Figure 2 and Figure 3 The projection surface of the second head onto the first head is not less than two-thirds of the plane of the first head, leaving enough area for placing the arc-shaped blank. In addition, the arc-shaped blank can be moved tangentially when the second head rotates, so that the engraving effect of the arc-shaped blank is not weaker than that of the square blank.

[0029] See attached document Figure 3 and Figure 4 One end of the wing bolt 13 is threadedly connected to a support plate 14, so that when the wing bolt 13 rotates clockwise, it can extend into the support plate 14 along the thread; conversely, when the wing bolt 13 rotates counterclockwise, it gradually moves away from the support plate 14. Since the support plate 14 is slidably installed inside the cabinet 1, the staff can pull the wing bolt 13 to drive the support plate 14 to slide along the strip hole 12, so that the wing bolt 13 can lock the arc-shaped blank in different positions. The width of the support plate 14 is greater than the width of the strip hole 12 to prevent the support plate 14 from falling off the strip hole 12 when it is pulled by the wing bolt 13, so as to stably support the wing bolt 13.

[0030] See attached document Figure 3 and Figure 4 The butterfly bolt 13 is provided with a friction plate 15 and a bent rod 16 on the outside. The friction plate 15 adopts a ceramic alloy composite structure, wherein the ceramic layer is in contact with the second head and the alloy layer is welded to the bent rod 16. The wing bolt 13 is used to press the friction plate 15 when it is turned in the forward direction. The friction plate 15 contacts the opening of the strip hole 12, so that the friction plate 15 drives the bent rod 16 to be suspended outside the strip hole 12 under the friction action, thereby supporting the blank in the arc groove 11. For example, in this embodiment, four sets of butterfly bolts 13, friction plates 15, and bent rods 16 are configured in each strip hole 12. Two bent rods 16 abut against the two ends of the arc-shaped blank, and the other two bent rods 16 abut against the ribs of the arc-shaped blank, thereby achieving stable clamping of the arc-shaped blank and avoiding the displacement of the arc-shaped blank due to inertia caused by the rotation of the second head, which helps to improve the accuracy of the rotational engraving of the arc-shaped blank.

[0031] The working principle of this utility model is as follows: When working, the brake motor 10 is started to rotate the load-bearing shaft 8, which drives the double-headed worktable 9 to rotate, so as to realize the alternating exposure of the first head and the second head.

[0032] When the second head is exposed, the arc-shaped blank can be placed into the arc-shaped groove 11 to limit the horizontal movement of the arc-shaped blank. The wing bolt 13 is pulled to drive the support plate 14 to slide along the strip hole 12 until it reaches the designated position. The wing bolt 13 is then turned in the forward direction to press against the arc-shaped blank. The friction plate 15 drives the bent rod 16 to suspend outside the strip hole 12 under the action of friction, thereby supporting the blank in the arc-shaped groove 11.

[0033] When carrying the curved blank, the laser generator 6 is activated to provide a laser beam to the laser engraving head 5. The laser collimator is translated in the XY plane using the electric drag chain guide 4 and the built-in miniature linear electric guide. Under the drive of the brake motor 10, the second head can rotate the curved blank at a uniform speed, so that the laser beam moves relative to the curved blank to engrave patterns or text.

[0034] At the same time, two bent rods 16 abut against the two ends of the arc-shaped blank, and two other bent rods 16 abut against the ribs of the arc-shaped blank, thereby achieving stable clamping of the arc-shaped blank and preventing the arc-shaped blank from shifting due to inertia as the second head rotates.

[0035] When the first head is outside, the square blank can be placed flat in the center of the first head and supported. Similarly, the laser generator 6 is used to engrave patterns or text at the designated position on the square blank.

[0036] The above description is merely an optional embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the field.
