Description

1. Description of Lifting Transfer Structure and Laser Processing Equipment Technical Field This invention relates to the field of laser cutting technology, and particularly to a lifting transfer structure and laser processing equipment. 5. Background Technology Laser cutting is a high-precision and high-efficiency processing technology. It utilizes a high-energy-density laser beam to irradiate the surface of a workpiece, causing the material to rapidly melt, vaporize, ablate, or reach its ignition point, thereby achieving the purpose of cutting. Laser cutting has advantages such as fast cutting speed, high precision, small heat-affected zone, narrow kerf, and good edge quality. It can complete the cutting tasks of complex shapes and precision structures, and is an important processing tool in modern manufacturing. In existing laser processing equipment, a transport channel is usually set up to transport the products to be processed. When the pallet carrying the products moves along the transport channel to the designated position, the lifting mechanism lifts the pallet, removing it from the transport channel. Subsequently, through a gantry crane or other transfer mechanism, the pallet, along with the products on it, is transported to the laser cutting mechanism for cutting processing. After processing is completed, the pallet is transported back to the lifting mechanism by the gantry crane. The lifting mechanism descends, and the pallet returns to the transport channel, continuing to be transported along the transport channel to the next mechanism for processing. However, existing laser processing equipment suffers from low efficiency. When the lifting mechanism raises the current pallet for laser cutting, pallets located behind the transport channel are often blocked by the lifting mechanism in front, preventing them from continuing along the transport channel. Thus, although the laser cutting process itself is very rapid, the waiting time of the pallets in the transport channel results in low efficiency. Summary of the Invention The main objective of this invention is to provide a lifting and transfer structure and laser processing equipment designed to reduce waiting time and improve efficiency. To achieve the above objectives, the present invention proposes a lifting and passing structure, comprising: a transport mechanism having a transport channel and a conveying plane located within the transport channel, the conveying plane being used for transporting pallets; a lifting mechanism including a lifting drive and a lifting assembly located within the transport channel, the lifting assembly being connected to the output end of the lifting drive, the lifting assembly having a clearance space, a support plane located within the clearance space, and a lifting plane facing away from the clearance space; and a blocking mechanism located within the transport channel and adjacent to the lifting mechanism, the blocking mechanism being used to restrict the movement of the pallet along the transport channel; wherein, the lifting drive drives the lifting assembly to move up and down along a first direction, so that the lifting assembly has a first position, a second position, and a third position, the first direction being set at an angle to the extension direction of the transport channel; in the first position, the lifting plane is not higher than the conveying plane; In the second position, the lifting plane protrudes from the conveying plane, and the conveying plane is located in the clearance space or aligned with the supporting plane.10. In one embodiment, the transport mechanism forms a clearance groove, and the lifting mechanism further includes: a base disposed within the transport channel, and the lifting drive member disposed on the base; and a lifting plate disposed on the base, one end of the lifting plate being connected to the output end of the lifting drive member, and the other end of the lifting plate being connected to the lifting assembly, the lifting assembly being movably disposed within the clearance groove; wherein the lifting drive member drives the lifting plate to move the lifting assembly, so that the lifting assembly moves within the clearance groove along the first direction. In one embodiment, the lifting assembly includes a support plate, a support column, and a lifting plate. The support column is movably disposed within the clearance groove, and both ends of the support column are respectively connected to the support plate and the lifting plate. The support plate is connected to the lifting plate, and clearance holes for avoiding the transport mechanism are formed on both sides of the support plate and the lifting plate. The surface of the lifting plate forms the lifting plane, the surface of the support plate forms the support plane, and the clearance space is formed between the lifting plate and the support plate. In one embodiment, the blocking mechanism includes: a blocking base disposed within the transport channel and located in front of the lifting mechanism along the extension direction of the transport channel; a blocking drive member disposed on the blocking base; a blocking connector disposed at the output end of the blocking drive member; and a blocking head connected to the blocking connector; wherein the blocking drive member drives the blocking connector, causing the blocking head to move along the first direction to limit the position of the tray. In one embodiment, the blocking connector has a mounting groove, and the blocking head is mounted in the mounting groove via a first rotating shaft. The first rotating shaft is fitted with a first elastic member, and both ends of the first elastic member are elastically connected to the blocking head and the mounting groove, respectively. In one embodiment, the blocking head is provided with a limiting bearing, which is used to limit contact with the tray. In one embodiment, the lifting and passing structure further includes a backstop mechanism located within the transport channel and on the side of the lifting mechanism away from the blocking mechanism. The backstop mechanism is used to restrict the movement of the pallet along the transport channel.10. In one embodiment, the check mechanism includes: a check base disposed within the transport channel and located on the side of the lifting mechanism away from the blocking mechanism; a check connector disposed on the check base; and a check block movably mounted on the check connector via a second rotating shaft, wherein a second elastic member is sleeved on the second rotating shaft, and both ends of the second elastic member are respectively connected to the check connector and the check block. One end of the check block near the lifting mechanism is higher than the transport plane, and the other end of the check block is not higher than the transport plane. In one embodiment, the transport mechanism includes a first frame and a second frame disposed opposite to each other, and the transport channel is formed between the first frame and the second frame. Both the first frame and the second frame are rotatably provided with a plurality of fixed wheels, which are arranged along the extension direction of the transport channel, and the surface of the fixed wheels forms the transport plane. The present invention also proposes a laser processing device, which includes the above-described lifting and passing structure. The technical solution of this invention uses a blocking component to limit the pallet at the lifting mechanism. The lifting mechanism has a lifting plane and a clearance space, so that when the lifting component moves along the first direction, it can keep the lifting plane no higher than the conveying plane in the first position, facilitating the unobstructed passage of the pallet. In the second position, the lifting plane is raised and the conveying plane is located in the clearance space, allowing the pallet to pass through the clearance space without obstruction, thereby effectively solving the problem of low transportation efficiency caused by the pallet being blocked by the lifting mechanism in existing equipment. 30 HK 20134897 A 4 Brief Description of the Drawings To more clearly illustrate the technical solutions in the embodiments of this invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below.

It utilizes a high-energy-density laser beam to irradiate the surface of a workpiece, causing the material to rapidly melt, vaporize, ablate, or reach its ignition point, thereby achieving the purpose of cutting. Laser cutting has advantages such as high cutting speed, high precision, small heat-affected zone, narrow kerf, and good edge quality. It can complete the cutting tasks of complex shapes and precision structures and is an important processing tool in modern manufacturing. 20 In existing laser processing equipment, a transport channel is usually set up to transport the products to be processed. When a pallet carrying products moves along the transport channel to a designated position, a lifting mechanism lifts the pallet, removing it from the transport channel. Subsequently, via a gantry crane or other transfer mechanism, the pallet, along with the products on it, is transported to the laser cutting mechanism for cutting. After processing, the pallet is transported back to the lifting mechanism by the gantry crane, the lifting mechanism lowers, and the pallet returns to the transport channel to continue its journey to the next mechanism for processing. However, existing laser processing equipment suffers from low efficiency. When the lifting mechanism lifts the current pallet for laser cutting, pallets located behind in the transport channel are often blocked by the lifting mechanism in front, preventing them from continuing along the transport channel. Thus, although the laser cutting process itself is very fast, the waiting time of the pallets in the transport channel results in low efficiency. The main objective of this invention is to provide a lifting station structure 100 and a laser processing device 200, aiming to reduce waiting time and improve efficiency. Referring to Figures 1 to 7, in one embodiment of the present invention, the lifting station structure 100 includes a transport mechanism 1, a lifting mechanism 2, and a blocking mechanism 3. The transport mechanism 1 has a transport channel 11 and a conveying plane 12 located within the transport channel 11, the conveying plane 12 being used to transport pallets. The lifting mechanism 2 includes a lifting drive 21 and a lifting assembly 22 disposed within the transport channel 11. The lifting assembly 22 is connected to the output end of the lifting drive 21. The lifting assembly 22 has a clearance space 223, a support plane 2221 located within the clearance space 223, and a lifting plane 2211 facing away from the clearance space 223. The blocking mechanism 3 is disposed within the transport channel 11 and adjacent to the lifting mechanism 2, and the blocking mechanism 3 is used to restrict the movement of the pallet along the transport channel 11.In this embodiment, the lifting drive 21 drives the lifting assembly 22 to move up and down along a first direction, so that the lifting assembly 22 has a first position, a second position, and a third position. The first direction is set at an angle to the extension direction of the transport channel 11. In the first position, the lifting plane 2211 is not higher than the transport plane 12; in the second position, the lifting plane 2211 protrudes from the transport plane 12, and the transport plane 12 is located in the clearance space 223 or aligned with the support plane 2221. In this embodiment, the blocking assembly limits the pallet at the lifting mechanism 2 for lifting. The lifting mechanism 2 is provided with a lifting plane 2211 and a clearance space 223, so that when the lifting assembly 22 moves along the first direction, it can keep the lifting plane 2211 not higher than the transport plane 12 in the first position, so that the pallet can pass through unobstructed. In the second position, the lifting plane 2211 is raised and the conveying plane 12 is located in the clearance space 223, allowing the pallet to pass through the clearance space 223 without obstruction. This effectively solves the problem of low transportation efficiency caused by the pallet being blocked by the lifting mechanism 2 in existing equipment. It is understandable that in the first position, the lifting plane 2211 not being higher than the conveying plane 12 includes two situations: one is that the lifting plane 2211 is lower than the conveying plane 12, and the other is that the lifting plane 2211 is aligned with the conveying plane 12. When the lifting plane 2211 is lower than the conveying plane 12, the pallet passes through the lifting mechanism 2 without obstruction, and the lifting station structure 100 only serves a transportation function. When the lifting plane 2211 is aligned with the conveying plane 12, the pallet can either continue to move along the extension direction of the transport channel 11 or be temporarily stored at the lifting mechanism 2 with the help of the blocking mechanism 3. In this case, the support of the lifting plane 2211 reduces the pressure on the conveying plane 12, thereby reducing wear and extending service life. Similarly, in the second position, the lifting plane 2211 is higher than the conveying plane 12 to lift the pallet. Two scenarios exist here. When the conveying plane 12 is located in the clearance space 223, the supporting plane 2221 is lower than the conveying plane 12, and the pallet passes directly through the clearance space 223 via the conveying plane 12, avoiding waiting time. When the conveying plane 12 is aligned with the supporting plane 2221, the pallet can be temporarily stored at the lifting mechanism 2 using the blocking mechanism 3, which will not be elaborated further. Temporarily storing the pallet at the lifting mechanism 2 facilitates adjustments to the production flow to accommodate different production speeds. It should be noted that in this embodiment, the first direction is perpendicular to the extension direction of the transport channel 11, allowing the lifting assembly 22 to quickly switch between the first and second positions.Optionally, depending on the specific layout of the production line, the size and weight of the pallets, and the conveying speed, the first direction can also be flexibly adjusted to an inclined direction. This not only better accommodates pallets of different shapes and sizes but also reduces the impact and vibration of the pallets during placement and transfer to a certain extent, further improving the stability during movement. Referring to Figures 3 and 6, in one embodiment, the transport mechanism 1 has a clearance groove 13, and the lifting mechanism 2 further includes a base 23 and a lifting plate 24. The base 23 is located within the transport channel 11, and the lifting drive member 21 is located on the base 23; the lifting plate 24 is located on the base 23, and one end of the lifting plate 24 is connected to the output end of the lifting drive member 21, while the other end of the lifting plate 24 is connected to the lifting assembly 22, which is movably disposed within the clearance groove 13. The lifting drive member 21 drives the lifting plate 24 to move the lifting assembly 22, causing the lifting assembly 22 to move along the first direction within the clearance groove 13. 15. In this embodiment, the lifting mechanism 2 includes a base 23, a lifting drive component 21, a lifting plate 24, and a lifting assembly 22. The base 23 is installed in the transport channel 11, serving as the supporting foundation for the entire lifting mechanism 2. The lifting drive component 21 can be a cylinder, hydraulic cylinder, or motor, etc., and is mounted on the base 23 to provide power. The lifting plate 24 serves as a connecting structure, connecting the output end of the lifting drive component 21 and the lifting assembly 22. The lifting assembly 22 is movably disposed within the clearance groove 13. The lifting drive component 21 drives the lifting plate 24, causing the lifting assembly 22 to move along a first direction, thereby forming a first position and a second position. Referring to Figures 3 and 6, in one embodiment, the lifting assembly 22 includes a support plate 222, a support column 224, and a lifting plate 221. The support column 224 is movably disposed within the clearance groove 13, and both ends of the support column 224 are connected to the support plate 222 and the lifting plate 221, respectively. The support plate 222 is connected to the lifting plate 24. Both sides of the support plate 222 and the lifting plate 221 have clearance holes 2212 for the transport mechanism 1. The surface of the lifting plate 221 forms a lifting plane 2211, and the surface of the support plate 222 forms a support plane 2221. A clearance space 223 is formed between the lifting plate 221 and the support plate 222. In this embodiment, the support plate 222 is connected to the lifting plate 24, and the lifting plate 24 is used to drive the support plate 222 to move along a first direction. Support column 224 is located on the end face of support plate 222 away from lifting plate 24, and lifting plate 221 is located on support column 224, thus forming a frame structure. The height of support column 224 can be adjusted according to the height of the product carried by the pallet.Understandably, a clearance groove 13 is provided on the transport mechanism 1, and the support column 224 is movably disposed within the clearance groove 13. This allows the support column 224 to be embedded within the transport mechanism 1, preventing interference between the pallet and the support column 224 when the pallet moves along the extension direction of the transport channel 11. Clearance holes 2212 are provided on both sides of the lifting plate 221 and the support plate 222, corresponding to the support column 224 on the same side. This prevents interference between the lifting plate 221 and the support plate 222 and the transport mechanism 1 when the lifting assembly 22 moves along the first direction. Referring to Figures 2 and 4, in one embodiment, the blocking mechanism 3 includes a blocking base 31, a blocking drive member 32, a blocking connector 33, and a blocking head 34. The blocking base 31 is disposed within the transport channel 11 and is located in front of the lifting mechanism 2 along the extension direction of the transport channel 11. The blocking drive member 32 is disposed on the blocking base 31. A blocking connector 33 is located at the output end of the blocking drive 32. A blocking head 34 is connected to the blocking connector 33. The blocking drive 32 drives the blocking connector 33, causing the blocking head 34 to move along a first direction to limit the movement of the pallet. In this embodiment, the blocking base 31 serves as the supporting foundation for the entire blocking mechanism 3. It is located within the transport channel 11 and extends along the direction of the transport channel 11, positioned in front of the lifting mechanism 2, ensuring that the pallet can be blocked in time when it is near the lifting mechanism 2. The blocking drive 32 can be a cylinder, hydraulic cylinder, or motor, etc., to provide driving force. The blocking connector 33 connects the output end of the blocking drive 32 and the blocking head 34. The blocking head 34 contacts the pallet, acting as a limiter. When the pallet moves along the transport channel 11 and approaches the lifting mechanism 2, the blocking drive 32 drives the blocking connector 33, causing the blocking head 34 to move along the first direction, protruding from the transport plane 12, thereby blocking the movement of the pallet. Referring to Figure 4, in one embodiment, the blocking connector 33 has a mounting groove 331. The blocking head 34 is mounted in the mounting groove 331 via a first rotating shaft 332. A first elastic member 333 is sleeved on the first rotating shaft 332, and both ends of the first elastic member 333 are elastically connected to the blocking head 34 and the mounting groove 331, respectively. In this embodiment, the blocking head 34 is mounted in the mounting groove 331 via the first rotating shaft 332, and the first elastic member 333 is also sleeved on the first rotating shaft 332. When the blocking head 34 contacts the tray, the first elastic member 333 can absorb part of the impact force, reduce the vibration caused by the collision, and thus protect the tray and the blocking mechanism 3 from damage. The first elastic member 333 can be made of an elastic material such as a spring, torsion spring, or elastic rubber.Referring to Figure 4, in one embodiment, the blocking head 34 is provided with a limiting bearing 341, which is used to limit contact with the pallet. In this embodiment, the limiting bearing 341 is rotatably provided on the blocking head 34. When the pallet moves along the transport channel 11 and contacts the limiting bearing 341, the limiting bearing 341 will roll slightly, thereby reducing the friction between the pallet and the blocking head 34. This not only improves the stability and accuracy of the blocking mechanism 3, but also significantly extends the service life of the blocking head 34 and the pallet. 5 Further, a laser sensor 35 is also provided on the blocking base 31 to detect the position of the pallet located on the lifting assembly 22. Referring to Figures 2 and 5, in one embodiment, the lifting station structure 100 also includes a check mechanism 4. The check mechanism 4 is located in the transport channel 11 and on the side of the lifting mechanism 2 away from the blocking mechanism 3. The check mechanism 4 is used to limit the movement of the pallet along the transport channel 11. 10. Understandably, the check mechanism 4 is used to prevent the pallet from moving away from the blocking mechanism 3. Through the cooperation of the blocking mechanism 3 and the check mechanism 4, the pallet can be accurately lifted by the lifting plate 221. Referring to Figure 5, in one embodiment, the check mechanism 4 includes a check base 41, a check connector 42, and a check block 43. The check base 41 is located in the transport channel 11 and on the side of the lifting mechanism 2 away from the blocking mechanism 3. The check connector 42 is located on the check base 41. The check block 43 is movably mounted on the check connector 42 via a second rotating shaft 421, and the second rotating shaft 421 is fitted with a second elastic member. The two ends of the second elastic member are respectively connected to the check connector 42 and the check block 43. The end of the check block 43 near the lifting mechanism 2 is higher than the transport plane 12, and the other end of the check block 43 is not higher than the transport plane 12. In this embodiment, the check base 41 serves as the supporting foundation for the check mechanism 4. It is located within the transport channel 2011 and on the side of the lifting mechanism 2 away from the blocking mechanism 3. The check connector 42 connects the check block 43 and the check base 41, and provides an installation position for the check block 43. The check block 43 is rotatably mounted on the check connector 42 via a second rotating shaft 421 and is tilted. The second rotating shaft 421 is also fitted with a second elastic element (not shown). When the pallet moves along the transport channel 11, the pallet first contacts the lower end of the check block 43. As the pallet continues to move forward, the higher end of the check block 43 is gradually pressed down, the second elastic element is compressed, and elastic potential energy is stored until the pallet has completely passed through. At this time, the second elastic element releases its elastic potential energy, quickly pushing the check block 43 back to its original position, thereby causing the higher end of the check block 43 to abut against the pallet, effectively preventing the pallet from moving backward.Optionally, in other embodiments, the check mechanism 4 can also be configured as a lifting structure. After the pallet has completely passed through the check mechanism 4, the check mechanism 4 moves again in the first direction to protrude from the conveying plane 30 HK 20134897 A 10 12, thereby preventing the pallet from moving backward. Referring to Figures 1 and 6, in one embodiment, the transport mechanism 1 includes a first frame 14 and a second frame 15 arranged opposite to each other. A transport channel 11 is formed between the first frame 14 and the second frame 15. Both the first frame 14 and the second frame 15 are rotatably equipped with a plurality of fixed wheels 141. The plurality of fixed wheels 141 are arranged along the extension direction of the transport channel 11, and the surface of the fixed wheels 141 forms the conveying plane 12. In this embodiment, the pallet's side is limited by the oppositely arranged first frame 14 and second frame 15 to facilitate the transport of the pallet. A transport channel 11 is formed between the first frame 14 and the second frame 15. Multiple fixed wheels 141 are provided on the side of both the first frame 14 and the second frame 15 closest to the transport channel 11. These fixed wheels 141 are arranged along the extension direction of the transport channel 11, and a conveying plane 12 is formed on the surface of each fixed wheel 141 for transporting pallets. A clearance groove 13 is formed between adjacent fixed wheels 141, and a support column 224 is movably disposed within the clearance groove 13. Since the structures of the first frame 14 and the second frame 15 are similar, the first frame 14 will be used as an example for detailed description below. The first frame 14 also includes a transport drive component 142, a transmission wheel 143, an auxiliary wheel 144, and a transmission belt 145. The transport drive component 142 is located on the first frame 14 and is used to provide power. Multiple drive wheels 143 are located on the side of the first frame 14 facing away from the transport channel 11 and arranged along the extension direction of the transport channel 11. Each drive wheel 143 corresponds to a fixed wheel 141, and the drive wheel 143 and the fixed wheel 141 are connected by a drive shaft. Multiple auxiliary wheels 144 are located on the side of the first frame 14 facing away from the transport channel 11, and each auxiliary wheel 144 is located between two adjacent drive wheels 143 and at different heights from the two drive wheels 143 along a first direction. The auxiliary wheels 144 serve as additional support points, effectively distributing the tension of the drive belt 145, so that the drive belt 145 can maintain a close fit with the drive wheels 143 along its entire length. The drive belt 145 is tensioned at the output end of the drive member, the drive wheels 143, and the auxiliary wheels 144. The transport drive member 142 drives the drive belt 145, which in turn drives the drive wheels 143 and the auxiliary wheels 144, causing the fixed wheel 141 to rotate, thereby moving the pallet.In this embodiment, the transmission belt 145 is a chain. Compared to traditional belts, chains have higher strength and can withstand greater tension and torque, thus ensuring stable transmission performance even under long-term operating conditions. Furthermore, the combination of the chain and gears enables more precise power transmission and reduces errors caused by vibration. Optionally, to accommodate pallets of different widths, the first frame 14 and the second frame 15 can move relative to each other. One of the first frame 14 and the second frame 15 is equipped with a slide rail, and the other slides on it, thereby achieving width adjustment. Optionally, to further ensure the stability of the pallet during transport in the transport channel 11, the first frame 30 HK 20134897 A 11 14 and the second frame 15 are also equipped with multiple rolling bearings 146. These rolling bearings 146 are arranged along the extension direction of the transport channel 11. When the pallet is located on the conveying plane 12, the opposite sides of the pallet abut against the rolling bearings 146 on the first frame 14 and the second frame 15, thereby reducing the frictional resistance between the pallet and the first and second frames 14 and reducing energy consumption. Optionally, the first frame 14 and / or the second frame 15 are equipped with a detection sensor 147 for detecting the pallet's position. This facilitates the control of the lifting assembly 22 to switch between the first and second positions after the pallet reaches the lifting station structure 100. This invention also proposes a laser processing device 200, which includes a lifting station structure 100. The specific structure of the lifting station structure 100 is as described in the above embodiments. Since this laser processing device 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solution of the above embodiment 10, which will not be described in detail here. Please refer to Figures 1 and 7. In one embodiment, the laser processing device 200 includes a base, multiple lifting station structures 100, multiple laser cutting mechanisms 201, and a transfer mechanism 202. The base is provided with a conveying channel for transporting a pallet, and the conveying channel forms multiple lifting positions. Multiple lifting station structures 100 are provided on the base, and each lifting station structure 100 corresponds to a lifting position. Each lifting station structure 100 is provided with a lifting plane 2211 and a clearance space 223. The lifting plane 2211 is used to lift the pallet. Multiple laser cutting mechanisms 201 are provided on the base and are arranged adjacent to the conveying channel. The transfer mechanism 202 is located on the base and is used to transport the pallet between the lifting plane 2211 and the laser cutting mechanism 201. The transfer mechanism 202 can be configured as a gantry crane or a robotic arm or other transport device. The lifting and passing structure 100 drives the lifting plane 2211 and the clearance space 223 to move to form a first position and a second position.20 In the first position, the lifting plane 2211 and the clearance space 223 are not higher than the conveying plane 12; in the second position, the lifting plane 2211 is higher than the conveying plane 12, the conveying plane 12 is located in the clearance space 223, and the pallet passes through the clearance space 223. When a lifting station structure 100 detects that a pallet is being transported, it drives the lifting plane 2211 to lift the pallet at the current position to a position suitable for transport by the transfer mechanism 202. At the same time, the clearance space 223 of the lifting station structure 100 ensures that even when the lifting plane 2211 is processing the current pallet, subsequent pallets can pass normally through the current lifting station structure 100 and continue to move forward to the next lifting position for processing at the next lifting position. This not only avoids the waiting time of the pallet during the processing, allowing each pallet to receive laser cutting processing in the shortest possible time, but also greatly improves the efficiency of the entire processing flow. Whether a pallet is being processed or is waiting to be processed, it can be processed simultaneously without any delay in any step affecting the progress of the entire processing flow.
