Description

Technical Field

[0002] A laser cutting machine cutting quality inspection feedback device is a device used to monitor and evaluate the cutting quality in real time during the laser cutting process. It provides feedback information by detecting and analyzing key parameters in the cutting process, helping to optimize the cutting process and ensure cutting accuracy and stability.

[0003] Existing laser cutting machine quality inspection feedback devices typically use screws to mount the machine body onto the laser emitter. The machine body then emits a laser beam towards the object being cut and receives the reflected light. Utilizing optical principles and signal processing technology, it accurately calculates parameters such as displacement, distance, thickness, and vibration of the target object, ensuring that the optimal height is maintained throughout the cutting process and avoiding cutting quality problems caused by distance deviations. When the workpiece surface is uneven or the material thickness changes, the machine body detects and feeds back the data in real time, automatically adjusting the height of the cutting head and the laser power to ensure consistent cutting results.

[0004] However, in actual use, when installing the machine body onto the laser cutting machine, the operator needs to tighten multiple screws individually, which is a cumbersome process and affects the ease of installation. At the same time, tightening the screws can cause permanent damage to the connection between the machine body and the cutting machine, affecting its service life. Utility Model Content

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-4As shown, this utility model provides a technical solution: a laser cutting machine cutting quality detection feedback device, including a body 1, a connecting device 2 and a protective device 3 on one side of the body 1, the connecting device 2 including a card seat 21, an adhesive tape 22 fixedly connected to one side of the card seat 21, a spring rod 23 slidably connected to the inner wall of the card seat 21, the other end of the spring in the spring rod 23 being fixedly connected to the card seat 21, a perforated rod 27 fixedly connected to one side of the body 1, the surface of the perforated rod 27 being slidably connected to the inner wall of the card seat 21, the size and shape of the surface of the spring rod 23 being adapted to the size and shape of the inner wall of the perforated rod 27, by setting the connecting device 2, the card seat 21 is first fixed to the laser cutting machine by adhesive tape, or fixed to the cutting machine by welding and screws, etc., at this time the spring rod 23 is manually moved. 3. Pull out the card holder 21 and manually move the machine body 1, causing the machine body 1 to move the multi-hole rod 27. When the multi-hole rod 27 moves to the position inside the card holder 21, the inner wall of any hole on the multi-hole rod 27 corresponds to the position of the spring rod 23. At this time, release the hand pulling the spring rod 23, and under the reaction force of the spring, the spring rod 23 moves towards the multi-hole rod 27, so that the spring rod 23 moves to the position inside the card holder 21 and the multi-hole rod 27 to fix the multi-hole rod 27 and the machine body 1, thereby achieving rapid assembly between the machine body 1 and the laser cutting machine. At the same time, the machine body 1 can be separated from the card holder 21 in the future to achieve convenient disassembly of the machine body 1. This allows personnel to install the machine body 1 on the cutting machine by means of snap-fit ​​fixing, reducing the damage to the machine body 1 during disassembly and assembly, and improving the convenience of disassembly and assembly of the machine body 1 and maintenance efficiency.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, a pull ring 24 is fixedly connected to one end of the spring rod 23. The inner side of the pull ring 24 is provided with multiple anti-slip protrusions. By setting the pull ring 24, the pull ring 24 can provide a force point for personnel to manually move the spring rod 23, improving the convenience of manually pulling the spring rod 23. A reinforcing plate 25 is fixedly connected to the right-angle part of the card seat 21. The surface of the reinforcing plate 25 is trapezoidal. By setting the reinforcing plate 25, the reinforcing plate 25 can support and reinforce the right-angle position of the card seat 21, reducing the tilting or deformation of the card seat 21 when subjected to force.

[0028] Specifically, such as Figure 2 and Figure 3As shown, a limiting groove 28 is provided on one side of the perforated rod 27, and a limiting block 26 is fixedly connected to the inner wall of the card holder 21. The surface size and shape of the limiting block 26 are adapted to the size and shape of the inner wall of the limiting groove 28. By setting the limiting block 26 and the limiting groove 28, the limiting block 26 can be inserted into the limiting groove 28 to limit the perforated rod 27, reducing the tilting of the perforated rod 27 after it is inserted into the card holder 21. The surface of the perforated rod 27 is provided with multiple protrusions, and the surface of the protrusions is spherical. By setting the protrusions, the protrusions can follow the perforated rod 27 into the card holder 21 and squeeze the inner wall of the card holder 21, increasing the fit between the perforated rod 27 and the inner wall of the card holder 21, and reducing the shaking of the perforated rod 27.

[0029] Specifically, such as Figure 4 As shown, the protective device 3 includes a support column 31, which is fixedly connected to the side of the body 1 near the laser head. An interception ring 32 is fixedly connected to the end of the support column 31 away from the body 1. By setting up the protective device 3, the interception ring 32 is first fixed to the position of the body 1 near the laser head through the support column 31, thus wrapping the laser head. When the laser head is about to collide with an object, the interception ring 32 works with the support column 31 to intercept the object, separating the object from the laser head and preventing them from contacting each other. This achieves protection for the laser head and reduces the possibility of the body 1 being accidentally hit by an object during use, causing damage to the laser head and affecting its normal use. This improves the safety of the laser head. An airbag 33 is fixedly connected to one side of the interception ring 32. By setting up the airbag 33, the airbag 33 can generate elasticity by compressing the air inside, buffering and releasing the impact and vibration generated by the object, further improving the protection effect for the laser head.

[0030] The working principle of this utility model is as follows:

[0031] S1. First, fix the card holder 21 to the laser cutting machine with adhesive tape, or fix the card holder 21 to the cutting machine by welding and screws. Then, manually pull the spring rod 23 out of the card holder 21 and manually move the machine body 1, so that the machine body 1 drives the multi-hole rod 27 to move. When the multi-hole rod 27 moves to the position of inserting into the card holder 21, the inner wall of any hole on the multi-hole rod 27 corresponds to the position of the spring rod 23. At this time, release the hand pulling the spring rod 23, and under the reaction force of the spring, the spring rod 23 moves towards the multi-hole rod 27, so that the spring rod 23 moves to the position of inserting into the card holder 21 and the multi-hole rod 27 to fix the multi-hole rod 27 and the machine body 1, thereby achieving quick assembly between the machine body 1 and the laser cutting machine. At the same time, the machine body 1 can be separated from the card holder 21 later to achieve convenient disassembly of the machine body 1.

[0032] S2. At this time, the machine body 1 emits a laser beam towards the object being cut through the laser head and receives the reflected light. Using optical principles and signal processing technology, it accurately calculates parameters such as displacement, distance, thickness, and vibration of the target object to ensure that the optimal height is maintained at all times during the cutting process, avoiding cutting quality problems caused by distance deviation. When the workpiece surface is uneven or the material thickness changes, the machine body 1 will detect and feed back data in real time, automatically adjusting the height of the cutting head and the laser power to ensure consistent cutting results. The model of the machine body 1 can be the KEYENCE series.

[0033] S3. First, the interception ring 32 is fixed to the body 1 near the laser head by the support column 31, and wraps the laser head. When the laser head is about to collide with an object, the interception ring 32 works with the support column 31 to intercept the object, separating the object from the laser head so that the two do not come into contact, thereby protecting the laser head.
