Description

Technical Field

[0001] This utility model relates to an anti-collision structure, and more particularly to an anti-collision structure for a laser dividing machine. Background Technology

[0002] Laser cutting uses a high-energy-density laser beam to irradiate the cutting area, causing the material surface to evaporate or melt, creating tiny kerfs and achieving the cutting purpose. Under the action of the laser, intense physicochemical changes occur on the material surface, causing the processed material to melt, evaporate, or decompose to form the cut. During laser cutting, errors often occur due to differences in the shape, position, and orientation of the object being cut, leading to impacts. This not only affects the processing quality but may also cause equipment damage and safety accidents.

[0003] Existing laser cutting machines typically have protective devices around the laser cutting head for protection. For example, a laser cutting machine anti-collision device with authorization announcement number CN221639847U includes: a device platform, a movable platform that is slidably mounted on the top of the device platform, an electric slide rail that is mounted on the top and bottom of the movable platform, and a slider that is slidably mounted on the bottom of the electric slide rail. Although the above patent can protect the laser cutting head from collisions, its protection range is limited to the four directions directly facing the protective plate, which is not comprehensive enough. Utility Model Content

[0004] In order to overcome the disadvantage of laser cutting heads being easily damaged by collisions, the technical problem of this utility model is to provide a collision-proof structure for a laser cutting machine.

[0005] The technical solution of this utility model is: a collision-proof structure for a laser cutting machine, including a base, a movable stage, a laser cutting head, a moving mechanism, a connecting plate, a first fixed plate, a second fixed plate, a protective plate, a fixed rod, a telescopic rod, a first elastic element, a moving block, a pushing rod, and a buffer mechanism. The movable stage is slidably mounted on the upper side of the base, and the laser cutting head is mounted on the lower side of the movable stage. The moving mechanism is located below the movable stage, and a connecting plate is located below the moving mechanism. The first fixed plate and the second fixed plate are located below the connecting plate. The first fixed plate and the second fixed plate are combined to form a protective shell. The interior of the protective shell... The space is divided into upper and lower sections. Multiple fixed rods are provided on the upper and lower sides of both sections. Each fixed rod is slidably connected to a telescopic rod, and each telescopic rod is connected to a moving block. A first elastic element surrounds the outside of the telescopic rod. One end of the first elastic element is connected to the fixed rod, and the other end is connected to the moving block. Multiple push rods are slidably provided on the first fixed plate. The end of the push rod closest to the second fixed plate contacts the moving block. The contact parts between the push rod and the moving block are both inclined surfaces. Each push rod has a buffer mechanism at the end furthest from the second fixed plate. The buffer mechanism is connected to a protective plate, which is arc-shaped.

[0006] Preferably, the buffer mechanism includes a telescopic frame, a fixed block, and a second elastic element. The end of the push rod away from the second fixed plate is rotatably provided with the telescopic frame, which is rotatably connected to the fixed block. The fixed block is connected to the protective plate, and the second elastic element is connected between the fixed block and the push rod.

[0007] Preferably, the moving mechanism includes an electric slide rail and a moving plate. The electric slide rail is installed on the side wall of the moving table, and the electric slide rail is slidably connected to the moving plate. The moving plate is connected to the connecting plate.

[0008] Preferably, it also includes rubber pads, with rubber pads provided in both the upper and lower spaces of the second fixing plate.

[0009] Preferably, it also includes a flexible folding plate, with each protective plate connected to the first fixed plate by a flexible folding plate, and the buffer mechanism located within the space formed by the protective plate, the first fixed plate and the flexible folding plate.

[0010] Preferably, a limiting plate is also included, with a limiting plate provided on the lower side of the connecting plate, and the limiting plate is circular.

[0011] The present invention has the following advantages: 1. The present invention, through the combined design of buffer mechanism, push rod, moving block, telescopic rod and first elastic element, can provide buffering effect when the laser cutting head is accidentally collided, and convert the kinetic energy generated by the collision into the elastic potential energy of the first elastic element, effectively reducing the impact force of the collision and avoiding damage to the laser cutting head. Moreover, the shape of the protective plate is matched with the buffer mechanism to provide multi-directional protection for the laser cutting head. Through the design of the rubber pad, additional buffering is provided during the collision, protecting the push rod and the second fixed plate from damage during the collision.

[0012] 2. The design of the elastic folding plate in this utility model not only protects the buffer mechanism from external factors such as dust and foreign objects, but also enhances the stability of the protective plate and prevents it from being accidentally displaced due to collision or vibration. The design of the moving mechanism allows the first fixed plate, the second fixed plate and the protective plate to be raised and lowered according to the working state of the laser cutting head, so that when the laser cutting head is not working, its sides are completely wrapped, providing better protection.

Detailed Implementation

[0020] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0021] A collision prevention structure for a laser cutting machine, such as Figures 1-6As shown, the device includes a base 1, a movable stage 2, a laser cutting head 3, a moving mechanism 4, a connecting plate 5, a first fixing plate 6, a second fixing plate 7, a protective plate 8, a fixing rod 9, a telescopic rod 10, a first elastic element 11, a moving block 12, a pushing rod 13, and a buffer mechanism. The movable stage 2 is slidably mounted on the upper side of the base 1. The laser cutting head 3 is mounted on the lower center of the movable stage 2. The moving mechanism 4 is located below the movable stage 2. The connecting plate 5 is located below the moving mechanism 4. The first fixing plate 6 and the second fixing plate 7 are located below the connecting plate 5. The second fixing plate 7 surrounds the outside of the laser cutting head 3 and does not contact the laser cutting head 3. The first fixing plate 6 and the second fixing plate 7 combine to form a protective shell. The interior of the protective shell is divided into upper and lower spaces, and both upper and lower spaces are equipped with... There are multiple fixed rods 9, with the upper and lower fixed rods 9 facing each other in pairs. Each fixed rod 9 is slidably connected to a telescopic rod 10, and each telescopic rod 10 is connected to a moving block 12. A first elastic element 11 surrounds the outside of the telescopic rod 10. One end of the first elastic element 11 is connected to the fixed rod 9, and the other end is connected to the moving block 12. The first fixed plate 6 has multiple through holes, and a push rod 13 is slidably provided in each through hole. The push rod 13 is located between two opposing moving blocks 12. The end of the push rod 13 near the second fixed plate 7 contacts the moving block 12. The contact parts of the push rod 13 and the moving block 12 are both inclined surfaces. Each push rod 13 has a buffer mechanism at the end away from the second fixed plate 7. The buffer mechanisms are connected to four protective plates 8 in groups of four. The protective plates 8 are arc-shaped.

[0022] When the laser cutting head 3 is working, if an accidental collision occurs, the object will first contact the protective plate 8. The buffer mechanism connected to the protective plate 8 will provide a certain buffering effect to reduce the impact force. At the same time, the buffer mechanism will push the push rod 13 connected to it to move towards the second fixed plate 7. Since the contact parts of the push rod 13 and the moving block 12 are both inclined surfaces, the push rod 13 will squeeze the two moving blocks 12 in contact with it to move up and down respectively. The moving blocks 12 will drive the telescopic rod 10 to move towards the fixed rod 9. At this time, the first elastic element 11 will contract, which will reduce the impact force generated by the push rod 13. The kinetic energy is converted into the elastic potential energy of the first elastic element 11, thereby reducing the impact force of the collision and preventing damage to the laser cutting head 3. After the conversion is complete, the first elastic element 11 recovers from the contracted state, driving the telescopic rod 10 to move. The telescopic rod 10 squeezes the push rod 13 to reset. When the laser cutting head 3 does not need to work, the moving mechanism 4 can drive the first fixed plate 6, the second fixed plate 7 and the protective plate 8 to descend, completely wrapping the side of the laser cutting head 3 and better protecting the laser cutting head 3. The shape of the protective plate 8, in conjunction with the buffer mechanism, can provide multi-directional protection for the laser cutting head 3.

[0023] like Figure 5 and Figure 6As shown, the buffer mechanism includes a telescopic frame 14, a fixed block 15, and a second elastic element 16. The end of the push rod 13 away from the second fixed plate 7 is rotatably equipped with the telescopic frame 14. The telescopic frame 14 is rotatably connected to the fixed block 15. The fixed block 15 is connected to the protective plate 8. The second elastic element 16 is connected between the fixed block 15 and the push rod 13. The telescopic frame 14 can ensure that the protective plate 8 will not fall due to gravity while ensuring telescopic extension. The second elastic element 16 can reset the protective plate 8 after the impact is mitigated. When the protective plate 8 is impacted, the protective plate 8 pushes the fixed block 15 connected to it to move. The fixed block 15 will push the elastic folding plate 18 and the second elastic element 16 to contract, converting the kinetic energy generated by the impact into elastic potential energy. If the impact force is too large and the kinetic energy is not completely converted, the remaining kinetic energy will drive the push rod 13 to move towards the second fixed plate 7, and finally be converted into the elastic potential energy of the first elastic element.

[0024] like Figure 1 and Figure 2 As shown, the moving mechanism 4 includes an electric slide rail 41 and a moving plate 42. The moving table 2 is equipped with electric slide rails 41 on both the front and rear sides and the left and right ends. The four electric slide rails 41 are connected to the two moving plates 42 in pairs. The two moving plates 42 are connected to the connecting plate 5. When the laser cutting head 3 is not working, the electric slide rail 41 drives the moving plate 42 to move downward. The moving plate 42 drives the connecting plate 5 and its lower parts to move downward, thereby completely covering the side of the laser cutting head 3.

[0025] like Figure 4 and Figure 5 As shown, it also includes a rubber pad 17. The second fixing plate 7 is provided with rubber pads 17 in both the upper and lower spaces. The rubber pads 17 are located between the upper and lower opposing moving blocks 12. The shape of the middle part of the rubber pad 17 matches the end of the push rod 13 near the second fixing plate 7. The rubber pad 17 can provide additional cushioning in the event of a collision, protecting the push rod 13 and the second fixing plate 7 from damage during the collision.

[0026] like Figure 4 As shown, it also includes an elastic folding plate 18. Each protective plate 8 is connected to the first fixed plate 6 by an elastic folding plate 18. The elastic folding plate 18 has a certain elasticity and can be folded. The buffer mechanism is located in the space formed by the protective plate 8, the first fixed plate 6 and the elastic folding plate 18. The elastic folding plate 18 can protect the buffer mechanism from external factors such as dust and foreign objects. At the same time, the elastic folding plate 18 connects the first fixed plate 6 and the protective plate 8, so that the protective plate 8 will not be accidentally displaced due to collision or vibration.

[0027] like Figure 3As shown, it also includes a limiting plate 19. The connecting plate 5 has a limiting plate 19 on its lower side. The limiting plate 19 is circular and surrounds the upper ends of the four protective plates 8. The protective plates 8 can slide within the range defined by the limiting plate 19. The limiting plate 19 limits the range of movement of the protective plates 8 and prevents the protective plates 8 from having excessive displacement.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
