[0028] The following combination Figure 1-Figure 4 The present invention is described in further detail.

[0029] The embodiment of the present invention discloses a fully automatic laminating laser die-cutting device. Figure 1 and Figure 2 The fully automatic laminating laser die-cutting equipment includes a frame 1, a laser fixing frame 2 and a laser cutting head 3, wherein the laser fixing frame 2 is a gantry frame, and the laser fixing frame 2 is arranged on the frame 1. Specifically, the laser fixing frame 2 can be fixedly arranged on the frame 1, or can be slidably arranged on the frame 1 along the length direction of the frame 1 by driving methods such as rodless cylinders and electric slide rails, which are not limited here. A sliding sleeve is provided on the laser fixing frame 2 with a sliding seat 4, and the sliding seat 4 can be driven to slide by a driving source such as a rodless cylinder and a hydraulic cylinder installed on the laser fixing frame 2, which is not limited here, and is helpful to realize the automation of the laser cutting process; the sliding direction of the sliding seat 4 is perpendicular to the length direction of the frame 1, and the laser cutting head 3 is fixedly installed on the lower surface of the sliding seat 4, which is helpful to laser cut the material passing below.

[0030] Reference Figure 2 and Figure 3, a dust suction component for absorbing smoke and dust is provided on the sliding seat 4, and blocking covers 5 are rotatably provided on the opposite sides of the laser fixing frame 2, and a rotating shaft 8 is fixedly penetrated on the blocking cover 5, and the rotating shaft 8 is rotatably provided on the laser fixing frame 2, and the rotating axis of the rotating shaft 8 is parallel to the sliding direction of the sliding seat 4. Specifically, the rotating shaft 8 is located between the upper surface and the lower surface of the sliding seat 4, and the laser cutting head 3 is located between the two blocking covers 5, which helps to reasonably limit the floating space of smoke and dust; the blocking cover 5 is arc-shaped, and the blocking cover 5 is convex in the direction away from the laser cutting head 3, so that the blocking cover 5 is not easy to affect the laser cutting of the material by the laser cutting head 3; a transmission component is provided on the laser fixing frame 2, and the transmission component is used to make the sliding seat 4 slide from the initial position toward the center of the laser fixing frame 2 for laser cutting, and adjust the blocking cover 5 to rotate in the direction close to the laser cutting head 3. The initial position of the sliding seat 4 is any end of the laser fixing frame 2. Specifically, the initial position of the sliding seat 4 is located at Figure 2 The right end of the middle laser fixing frame 2.

[0031] When the material is transported to the required position under the laser cutting head 3, the sliding seat 4 is driven to drive the laser cutting head 3 to move from the initial position of the sliding seat 4 to the center of the laser fixing frame 2, and the blocking cover 5 is adjusted by the transmission component to rotate in the direction close to the laser cutting head 3, so that the two blocking covers 5 are close to each other and cover the position where the material needs to be cut. When the sliding seat 4 is moved to the required position as needed, the laser cutting head 3 works to cut the material, and the smoke generated by the laser cutting is absorbed by the dust suction component. Since the two blocking covers 5 are close to each other, they cover the top of the laser cutting head 3 and the surroundings of the material cutting position, thereby limiting the dispersion of smoke to a certain extent, and blocking the smoke between the two blocking covers 5, it is convenient for the dust suction component to absorb the smoke, which helps to improve the smoke absorption effect; at the same time, the blocking cover 5 can also block the strong light generated by the laser cutting head 3 during cutting, thereby reducing damage to the operator's eyes.

[0032] Reference Figure 2 and Figure 3 In order to absorb the smoke generated by laser cutting, the dust collection assembly includes a pipe 16 passing through the sliding seat 4 and a dust collection nozzle 17 connected to the pipe 16. The dust collection nozzle 17 is close to the laser cutting head 3, and the end of the pipe 16 away from the dust collection nozzle 17 is used to connect with an external fume extractor. When laser cutting is performed, the external fume extractor is started, and the fume extractor absorbs the smoke generated by cutting through the dust collection nozzle 17 and the pipe 16.

[0033] Reference Figure 2 and Figure 3In order to facilitate the sliding seat 4 to slide from the initial position toward the center of the laser fixing frame 2 for laser cutting, the blocking cover 5 is adjusted to rotate toward the direction close to the laser cutting head 3. The transmission assembly includes an adjustment block 6, an adjustment rope 7, an elastic member and an adsorption member. The adjustment block 6 is slidably arranged on the laser fixing frame 2 along the vertical direction. Each blocking cover 5 corresponds to two adjustment blocks 6, and the two adjustment blocks 6 are respectively located at the opposite ends of the corresponding blocking cover 5. The adjustment block 6 is located above the corresponding blocking cover 5. The adjustment rope 7 corresponds to the adjustment block 6 one by one. The side of the blocking cover 5 is fixed with a connecting rod 1 8. The connecting rod 18 corresponds to the adjusting rope 7 one by one. One end of the adjusting rope 7 is fixed on the corresponding adjusting block 6, and the other end is fixed on the connecting rod 18 of the blocking cover 5. The adjusting rope 7 is inelastic and is in a tensioned state. The elastic member is arranged on the laser fixing frame 2. The elastic member is used to drive the blocking cover 5 to rotate toward the direction close to the laser cutting head 3. The adsorption member is arranged on the sliding seat 4. The adsorption member is used to adsorb the adjusting block 6 to slide in the direction away from the corresponding blocking cover 5. When the sliding seat 4 is in the initial position, the adsorption member adsorbs the adjusting block 6 to slide in the direction away from the corresponding blocking cover 5.

[0034] Reference Figure 2 and Figure 3 In order to facilitate the driving of the blocking cover 5 to rotate toward the direction close to the laser cutting head 3, the elastic member includes a torsion spring 9, which is movably mounted on the rotating shaft 8, one end of the torsion spring 9 is fixed to the laser fixing frame 2, and the other end is fixed to the blocking cover 5. When the torsion spring 9 is in a natural state, the end of the blocking cover 5 away from the rotating shaft 8 is at a certain distance from the material below. Since the smoke and dust float upward, it is not easy to float out from the gap between the blocking cover 5 and the material; at the same time, when the dust suction component absorbs the smoke and dust, the air can enter between the two blocking covers 5 from the gap below the blocking cover 5.

[0035] Reference Figure 2 and Figure 3 In order to facilitate the adsorption and adjustment block 6 to slide in the direction away from the corresponding blocking cover 5, a support plate 19 is fixed on the sliding seat 4, and the adsorption member includes a first magnet 10 and a second magnet 11. The support plate 19 corresponds to the first magnet 10 one by one, the first magnet 10 is fixed on the corresponding support plate 19 of the sliding seat 4, and the second magnet 11 is fixed on the adjustment block 6. The first magnet 10 corresponds to the second magnet 11 one by one, and the first magnet 10 is located above the corresponding second magnet 11. The first magnet 10 is used to adsorb the corresponding second magnet 11 to drive the adjustment block 6 to slide in the direction away from the blocking cover 5. The adsorption force between the first magnet 10 and the second magnet 11 is greater than the sum of the torsion of the torsion spring 9, the gravity of the blocking cover 5 and the gravity of the adjustment block 6. When the sliding seat 4 is in the initial position, the first magnet 10 close to the initial position side of the sliding seat 4 is aligned with the corresponding second magnet 11 and adsorbed and fixed.

[0036] When the sliding seat 4 is in the initial position, the first magnet 10 near the initial position side of the sliding seat 4 is aligned with the corresponding second magnet 11, and the first magnet 10 will absorb the second magnet 11 to drive the adjustment block 6 to slide in the direction away from the blocking cover 5. The adjustment block 6 pulls the corresponding blocking cover 5 through the adjusting rope 7 and the connecting rod 18 to rotate in the direction away from the laser cutting head 3, so that the torsion spring 9 is deformed and the two blocking covers 5 are unfolded, thereby facilitating the maintenance and inspection of the laser cutting head 3 when it is not in use; when it is necessary to cut the material, the sliding seat 4 moves from the initial position toward the direction close to the center of the laser fixing frame 2, so that the first magnet 10 is disengaged from the corresponding second magnet 11, and then the blocking cover 5 is rotated in the direction close to the laser cutting head 3 under the torsion force of the torsion spring 9, thereby limiting the range of laser cutting smoke dispersion, which helps to ensure the smoke adsorption effect.

[0037] Reference Figure 2 and Figure 3 The laser fixing frame 2 is provided with an adhesive member 12 for bonding and fixing the adjustment block 6 to the laser fixing frame 2, and the sliding seat 4 is provided with a pushing member for pushing the adjustment block 6 to slide in a direction close to the blocking cover 5; specifically, in order to facilitate bonding and fixing the adjustment block 6, a fixing plate (not marked in the figure) is fixed at one end of the laser fixing frame 2 close to the initial position of the sliding seat 4, and the fixing plate is located on the side of the support plate 19 away from the center of the laser fixing frame 2, and the adhesive member 12 includes a first Velcro 121 and a second Velcro 122, the first Velcro 121 is fixed on the fixing plate of the laser fixing frame 2, and the second Velcro 122 22 is fixed on the adjusting block 6 close to the side of the first Velcro 121, the first Velcro 121 is located above the second Velcro 122, the second Velcro 122 is located on the side of the second magnet 11 on the corresponding adjusting block 6 away from the center of the laser fixing frame 2, the first Velcro 121 is used to bond with the second Velcro 122, the bonding force between the first Velcro 121 and the second Velcro 122 is greater than the sum of the torsion of the torsion spring 9, the gravity of the blocking cover 5 and the gravity of the adjusting block 6, when the first magnet 10 and the second magnet 11 are bonded, the first Velcro 121 and the second Velcro 122 are bonded.

[0038] Reference Figure 2 and Figure 3 In order to facilitate the pushing of the adjusting block 6 to slide toward the direction close to the blocking cover 5, the pushing member includes a pushing rod 13 and abutment block 14. The pushing rod 13 is fixed on the sliding seat 4, and the abutment block 14 is fixed on the adjusting block 6 on the side close to the initial position of the sliding seat 4. The pushing rod 13 is located above the abutment block 14. The side of the abutment block 14 close to the pushing rod 13 is an arc surface, and the side of the arc surface close to the center of the laser fixing frame 2 is inclined upward. The pushing rod 13 is used to slide and abut with the arc surface. When the sliding seat 4 is in the initial position, the first Velcro 121 is bonded and matched with the second Velcro 122, and the pushing rod 13 is located on the side of the abutment block 14 away from the center of the laser fixing frame 2.

[0039] When performing straight-line cutting, the sliding seat 4 moves from the initial position toward the other end of the laser fixing frame 2. As the sliding seat 4 drives the pushing rod 13 to move, the first magnet 10 disengages from the corresponding second magnet 11, and the pushing rod 13 and the arc surface of the abutment block 14 slide relative to each other. The pushing rod 13 pushes the abutment block 14 to move downward, so that the first Velcro 121 and the second Velcro 122 disengage, and then the blocking cover 5 rotates toward the direction close to the laser cutting head 3 under the action of the torsion spring 9. The two blocking covers 5 approaching each other help to limit the range of smoke and dust dispersion generated at the laser cutting position. When the sliding seat 4 moves to the end of the laser fixing frame 2 away from the initial position to complete the straight-line cutting, the first magnet 10 on the end of the sliding seat 4 away from the initial position is aligned with the corresponding second magnet 11, so that the first The magnet 10 adsorbs the corresponding second magnet 11 to drive the adjustment block 6 to move upward, and the blocking cover 5 is pulled by the adjustment rope 7 to rotate in the direction away from the laser cutting head 3 until the first magnet 10 and the second magnet 11 are adsorbed and fixed, the first Velcro 121 and the second Velcro 122 are bonded, and the two blocking covers 5 open the laser cutting head 3; then the sliding seat 4 moves toward the initial position for reset, as the sliding seat 4 moves, the first magnet 10 and the second magnet 11 are separated, but the first Velcro 121 and the second Velcro 122 are still bonded, so that the two blocking covers 5 are in an open state, which helps to speed up the heat dissipation of the laser cutting head 3 and the cutting position, and then the sliding seat 4 is reset to the initial position, and the first magnet 10 on the side close to the initial position on the sliding seat 4 is adsorbed and fixed with the corresponding second magnet 11 to facilitate the next straight line cutting.

[0040] Reference Figure 2 and Figure 3 In order to improve the blocking effect of smoke generated by laser cutting, the sliding seat 4 is symmetrically fixed with retractable bellows 21 on both sides of the moving direction, and the end of the bellows 21 away from the sliding seat 4 is fixed to the corresponding end of the laser fixing frame 2, and the bellows 21 covers the rotating shaft 8. The setting of the bellows 21 can block the gap between the blocking cover 5 and the middle of the laser fixing frame 2, ensuring that the smoke generated by laser cutting is not easy to float out.

[0041] Reference Figure 3 and Figure 4 The blocking cover 5 is provided with a plurality of heat sinks 15, one end of the heat sink 15 is located on a side of the blocking cover 5 close to the laser cutting head 3, and the other end is located on a side of the blocking cover 5 away from the laser cutting head 3. The plurality of heat sinks 15 helps to improve the heat dissipation effect between the two blocking covers 5 during laser cutting.

[0042] Reference Figure 3 and Figure 4The heat sink 15 is slidably inserted into the blocking cover 5, and the heat sink 15 slides in a direction close to or away from the corresponding blocking cover 5. The sliding direction of the heat sink 15 is parallel to the length direction of the heat sink 15. A connecting plate 22 is fixed to the side of the multiple heat sinks 15 on the blocking cover 5 away from the laser cutting head 3. A spring 23 is fixed between the connecting plate 22 and the blocking cover 5. The extension direction of the spring 23 is parallel to the sliding direction of the heat sink 15. The setting of the spring 23 helps to relatively fix the positions of the multiple heat sinks 15; a sliding member is provided on the sliding seat 4 for adjusting the connecting plate 22 to slide in a direction close to or away from the corresponding blocking cover 5.

[0043] Reference Figure 3 and Figure 4 In order to facilitate the adjustment of the connecting plate 22 to slide toward or away from the corresponding blocking cover 5, the sliding member includes a third magnet 24 and a fourth magnet 25. The third magnet 24 is fixed on the side wall of the sliding seat 4. The third magnet 24 corresponds to the connecting plate 22 one by one. The connecting plate 22 corresponds to a plurality of fourth magnets 25. The plurality of fourth magnets 25 are fixed at intervals along the length direction of the connecting plate 22 on one side of the connecting plate 22 close to the corresponding blocking cover 5. The third magnet 24 is used to adsorb the fourth magnet 25 on the corresponding connecting plate 22 to drive the connecting plate 22 to move toward the direction close to the blocking cover 5. The adsorption force between the third magnet 24 and the fourth magnet 25 is greater than the elastic force of the spring 23. When the torsion spring 9 is in a natural state, the plane where the third magnet 24 is located is parallel to the plane where the fourth magnet 25 is located.

[0044] When laser cutting is performed, the two blocking covers 5 are close to each other, that is, the torsion spring 9 is in a natural state. At this time, the plane where the third magnet 24 is located is parallel to the plane where the fourth magnet 25 is located. When the sliding seat 4 moves on the laser fixing frame 2 for laser cutting, when the sliding seat 4 moves to align the third magnet 24 with the fourth magnet 25, the third magnet 24 absorbs the aligned fourth magnet 25 and drives the connecting plate 22 to move in the direction close to the blocking cover 5, compressing the spring 23, so that the heat sink 15 is further extended into the blocking cover 5, expanding the contact area between the heat sink 15 and the smoke; when the sliding seat 4 moves to the point where the third magnet 24 and the fourth magnet 25 are misaligned, the compressed spring 23 pushes the connecting plate 22 to drive multiple heat sinks 15 to move in the direction away from the blocking cover 5, so that the heated heat sink 15 moves outside the blocking cover 5, accelerating the heat dissipation. During the movement of the sliding seat 4, the reciprocating movement of the heat sink 15 helps to dissipate the air between the two blocking covers 5.

[0045] The other structures in the embodiment of the present invention are the same as those in the related art, and can also achieve bonding, heat drying and then laser cutting.

[0046] The implementation principle of the fully automatic laminating laser die-cutting equipment of the embodiment of the present invention is: when the sliding seat 4 is located at the initial position, the first magnet 10 close to the initial position side of the sliding seat 4 is adsorbed and fixed with the corresponding second magnet 11, the first Velcro 121 and the second Velcro 122 are bonded and matched, the push rod 13 is located on the side of the abutment block 14 away from the center of the laser fixing frame 2, the blocking cover 5 is in the expanded state, and the spring 23 is in the natural state.

[0047] When the material is transported to the required position under the laser cutting head 3, the sliding seat 4 is driven to drive the laser cutting head 3 to move from the initial position to the center of the laser fixing frame 2. As the sliding seat 4 drives the pushing rod 13 to move, the first magnet 10 close to the initial position of the sliding seat 4 is disengaged from the corresponding second magnet 11, and the pushing rod 13 and the arc surface of the abutment block 14 slide relative to each other. The pushing rod 13 pushes the abutment block 14 to move downward, so that the first Velcro 121 is disengaged from the second Velcro 122, and then the blocking cover 5 rotates toward the direction close to the laser cutting head 3 under the action of the torsion spring 9. The two blocking covers 5 are close to each other, and the laser cutting position on the material is located between the two blocking covers 5, which helps to limit the dispersion range of smoke generated at the laser cutting position.

[0048] Then the sliding seat 4 moves to the required position as needed, the laser cutting head 3 works to cut the material, and the external smoke extractor is started to absorb the smoke generated by the laser cutting. Since the two blocking covers 5 are close to each other, they cover the top of the laser cutting head 3 and the surrounding areas of the laser cutting position on the material, thereby limiting the dispersion of smoke to a certain extent, and blocking the smoke between the two blocking covers 5, making it convenient for the dust suction nozzle 17 to absorb the smoke, which helps to improve the smoke absorption effect; at the same time, the blocking cover 5 can also block the strong light generated by the laser cutting head 3 during cutting, thereby reducing damage to the operator's eyes.

[0049] The embodiment of the present invention also discloses a fully automatic laminating laser die-cutting process. The fully automatic laminating laser die-cutting process uses the above-mentioned fully automatic laminating laser die-cutting equipment and includes the following steps:

[0050] Step 1: The material is transported to the position below the laser cutting head 3, and the sliding seat 4 is driven by the rodless cylinder to drive the laser cutting head 3 to move from the initial position to the center of the laser fixing frame 2. The initial position of the sliding seat 4 is any end of the laser fixing frame 2;

[0051] Step 2: Then the first magnet 10 on the side close to the initial position of the sliding seat 4 is disengaged from the corresponding second magnet 11, and the push rod 13 pushes the abutment block 14 and the adjustment block 6 to move toward the direction close to the blocking cover 5, so that the first Velcro 121 is disengaged from the second Velcro 122, and then the deformed torsion spring 9 drives the blocking cover 5 to rotate toward the direction close to the laser cutting head 3, and the two blocking covers 5 are close to each other to cover the surroundings of the laser cutting position on the material;

[0052] Step 3: After the sliding seat 4 moves to the desired position, the laser cutting head 3 cuts the material, and the external smoke exhaust fan is started to absorb the smoke generated by the laser cutting through the dust suction nozzle 17 and the pipe 16.

[0053] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
