Description

Technical Field

[0001] This invention relates to the field of cutting technology, specifically a flexible light trough cutting device for adapting to the arc shape of ancient building tiles. Background Technology

[0002] With the increasing prevalence of ancient building preservation and nighttime lighting projects, traditional corrugated lights have revealed numerous limitations in their application on ancient building roofs. Currently, most corrugated lights on the market are independent, externally mounted, or semi-embedded structures. Installation typically requires adhesive application and clipping to the tiles or roof structure, and in some cases, even drilling holes and securing them with expansion bolts or screws. This method not only damages the integrity and waterproofing of the ancient building roof tiles but also easily leads to tile cracking and leaks, causing irreversible damage to the cultural relic itself.

[0003] To address the problems of existing corrugated lights, which generally use rigid shells and are difficult to adapt to the undulating curved surfaces of ancient building roof tiles, resulting in poor fit, lighting installation systems based on flexible light troughs have been widely adopted. A "flexible light trough" can be understood as a bendable lighting installation groove. Its core function is to overcome the limitation of traditional rigid light troughs being unable to bend, allowing the light to perfectly fit curved or non-linear architectural structures. It is not a single component but a system integrating multiple materials, typically composed of the following parts: Flexible trough body: This is the most crucial part, usually made of flexible aluminum alloy or flexible silicone.

[0004] With the development of the flexible light trough industry, various targeted processing equipment has been proposed. For example, an existing patent document (application publication number CN119407362A) discloses an intelligent cutting device for producing light strips, including a base frame, a receiving plate, and a laser cutter. The receiving plate is fixed on the base frame. The laser cutter is installed in the middle of the receiving plate. This invention uses several extrusion blocks to extrude the cut flexible light strips, causing odd-numbered strips to bend downwards and even-numbered strips to bend upwards, so that the cut strips are completely separated, preventing them from sticking together.

[0005] Taking the aforementioned cutting equipment as an example, when cutting flexible light troughs made of metal materials such as aluminum alloys, a laser cutter is used to achieve rapid cutting. However, during the cutting process, in order to facilitate material unloading, the clamping structure will avoid the cut flexible light trough. However, the flexible light trough itself can undergo a certain degree of bending deformation, and the cut flexible light trough is in an unsupported and suspended state, which will cause the flexible light trough to tilt during cutting. The lack of support in the cut area of ​​the flexible light trough can easily lead to uneven cross-sections or re-adhesion problems. Summary of the Invention

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: Figures 1-13 As shown, the present invention provides a flexible light trough cutting device for adapting to the arc shape of ancient building tiles, including a processing table 1 and a cutting structure. A magnet 2 is fixedly embedded on one side of the top of the processing table 1. Multiple guide components are detachably installed on the top of the processing table 1. Each of the multiple guide components is provided with a cutting support component at one end. A drive component is connected between the multiple cutting support components and the processing table 1. A hydraulic cylinder 3 is fixedly inserted on the processing table 1. A pressing component is installed on the piston end of the hydraulic cylinder 3.

[0023] Specifically, such as Figure 1 and Figure 2 In the cutting structure, two mounting brackets 8 are fixedly connected between the gantry 9 and the processing table 1. The gantry 9 is fixedly installed with a forward and reverse motor 10 and a guide frame 12. The lead screw 11, which is fixedly connected to the output end of the forward and reverse motor 10, is rotatably installed inside the gantry 9. The top of the laser cutting equipment 13 is fixedly connected with two mounting brackets 14. One mounting bracket 14 is threaded onto the outside of the lead screw 11, and the other mounting bracket 14 is sleeved on the outside of the guide frame 12. With the cooperation of the two mounting brackets 14 and the guide frame 12, the laser cutting equipment 13 moves back and forth inside the gantry 9.

[0024] Therefore, the forward and reverse motors 10 in the control cutting structure work, the lead screw 11 rotates, and the lead screw 11 drives the laser cutting equipment 13 through the mounting bracket 14 installed on the outer thread, so that the laser cutting equipment 13 moves, controls the forward and reverse motors 10 to work in the forward or reverse direction, and the laser cutting equipment 13 to move forward or backward, adjusts the position of the laser cutting equipment 13, and makes the laser cutting equipment 13 cut flexible lamp slots at different positions.

[0025] Specifically, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8The bottom of the metal support frame 15 in the guide assembly has multiple threaded holes 16. The bottom of the threaded holes 16 has two threaded holes 17 located on the top of the processing table 1. Some of the threaded holes 17 have mounting bolts 18 passing through them. The top of the mounting bolts 18 passes through the aligned threaded holes 16 and extends into the metal support frame 15. The mounting bolts 18 are threadedly connected to the metal support frame 15. The multiple mounting bolts 18 install the metal support frame 15 onto the top of the processing table 1. The metal support frame 15 can be removed from the top of the processing table 1 by simply rotating and removing the multiple mounting bolts 18 threaded on the metal support frame 15.

[0026] Support plates 20 are inserted into multiple guide slots 19 on the outer side of the metal support frame 15. One end of the support plate 20 is fixedly connected to the metal support frame 21. The multiple support plates 20 form a guide channel between the metal support frame 21 and the metal support frame 15. The guide channel ensures that the flexible light trough is still supported during the movement of the metal support frame 21. The limiting slots 22 on both sides of the metal support frame 15 are connected to the guide slots 19 on the same side. A crossbar 23 is provided between the two limiting slots 22. Both ends of the crossbar 23 are fixedly connected to the support plate 20 on the same side. The crossbar 23 and the guide slots 19 cooperate to limit the support plate 20 and the metal support frame 21, preventing the metal support frame 21 from completely detaching from the metal support frame 15 and ensuring that the metal support frame 21 and the metal support frame 15 are installed and disassembled as a whole.

[0027] In summary, the metal support frame 15, metal support frame 21, crossbar 23, and multiple support plates 20 in the guide assembly work together to form a retractable light trough guide rail. The light trough guide rail can be removed from the top of the processing table 1 simply by rotating the multiple mounting bolts 18 installed between the metal support frame 15 and the processing table 1 to disengage the mounting bolts 18 from the metal support frame 15.

[0028] Specifically, such as Figure 1 , Figure 3 and Figure 4 One of the mounting brackets 4 of the pressing assembly is fixedly installed on the piston end of the hydraulic cylinder 3. The second mounting bracket 5 is U-shaped. Both ends of part of the second mounting bracket 5 are inserted into the processing table 1, and both ends of the remaining second mounting bracket 5 are inserted into two third mounting brackets 8 respectively. The second mounting bracket 5 is limited to only move up and down. Both ends of the second mounting bracket 5 are fixedly connected to the two first mounting brackets 4 respectively.

[0029] Therefore, the hydraulic cylinder 3 is controlled to work, and the hydraulic cylinder 3 drives multiple mounting brackets 5 to move up and down through the mounting bracket 4.

[0030] A one-way bearing 7 is fixedly embedded on the outer side of the mounting bracket 2 5. A friction tube 6 is rotatably mounted on the outer side of the mounting bracket 2 5. The inner wall of the friction tube 6 is fixedly connected to the outer ring of the one-way bearing 7. Under the action of the one-way bearing 7, the friction tube 6 can only rotate in one direction.

[0031] Specifically, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 In the cut support assembly, fixed plates 30 are fixedly connected to both sides of fixed plate 4 31. Two fixed bent rods 29 are fixedly connected to the bottom of fixed plate 3 30. The metal support frame 3 33 set at the top of fixed plate 4 31 has two threaded holes 4 34 at its bottom. Mounting bolts 2 43 are inserted through the two threaded holes 3 32 at the top of fixed plate 4 31. The top of mounting bolts 2 43 extends through the aligned threaded holes 4 34 and into the metal support frame 3 33. Mounting bolts 2 43 are threadedly connected to metal support frame 3 33. Mounting bolts 2 43 fix metal support frame 3 33 to the top of fixed plate 4 31. Metal support frame 3 33 can be disassembled by simply rotating mounting bolts 2 43 to detach it from metal support frame 3 33. Metal support frame 3 33 can be quickly installed and disassembled.

[0032] Fixed plate 36 is fixedly connected to both piston ends of the dual-axis hydraulic cylinder 35, which is fixedly connected to the bottom of fixed plate 4 31. Two transmission slide rods 37 are fixedly connected to the side of fixed plate 5 36 near fixed plate 4 31. The transmission slide rods 37 pass through fixed plate 3 30 on the same side. A hydraulic sensor 42 is fixedly installed on the outside of the damper 38, which is fixedly connected between the two transmission slide rods 37. The hydraulic sensor 42 detects the hydraulic pressure inside the damper 38. The damper 38 passes through fixed plate 3 30 on the same side. Both sides of fixed plate 6 39, which is fixedly connected to the piston end of the damper 38, are fixedly connected to clamping plates 40. Two telescopic rods 41 are provided on one side of the clamping plate 40. The telescopic rods 41 pass through fixed plate 3 30 on the same side. The piston end of the telescopic rods 41 is fixedly connected to the clamping plate 40 on the same side. Fixed plate 6 39 moves back and forth under the action of fixed plate 4 31.

[0033] Therefore, when the dual-axis hydraulic cylinder 35 in the control cut support assembly is working, the two fixed plates 36 move closer or further away from each other, and the damper 38 and the fixed plate 39 connected to its piston end move synchronously. The fixed plate 39 and the two clamping plates 40 fixedly connected to it together form a clamping component. The two clamping components are respectively set on both sides of the metal support frame 33. When the dual-axis hydraulic cylinder 35 is working, the two clamping components move closer or further away from the metal support frame 33 synchronously.

[0034] Specifically, such as Figure 8, Figure 9 and Figure 10 In the drive assembly, multiple hanging vertical plates 44 are fixedly connected to the bottom of the processing table 1 on the outer side of the telescopic rod 24 and the outer side of the pneumatic cylinder 25. A fixing plate 26 is fixedly connected between the piston end of the telescopic rod 24 and the piston end of the pneumatic cylinder 25. The fixing plate 26 is fixedly connected to two fixing bent rods 29 in the cutting support assembly. Under the action of the telescopic rod 24 and the pneumatic cylinder 25, the multiple cutting support assemblies can move left and right.

[0035] Multiple fixed plates 27 are fixedly connected to one side of fixed plate 1 26, and electromagnets 28 are fixedly connected to the top of fixed plate 27. Electromagnets 28 correspond one-to-one with metal support frame 33.

[0036] Therefore, by controlling the operation of the pneumatic cylinder 25, the fixed plate 26 moves left and right, and multiple cut support components and multiple electromagnets 28 move left and right.

[0037] In summary, the lamp trough cutting equipment consists of a processing table 1, a cutting structure, a magnet 2, multiple guide components, multiple cutting support components, a drive component, a hydraulic cylinder 3, and a material clamping component. Connecting a human-machine interface device to control the lamp trough cutting equipment is existing technology and will not be elaborated upon here.

[0038] The working principle of the light trough cutting equipment is as follows: Furthermore, simply rotating the multiple mounting bolts 18 installed between the metal support frame 15 and the processing table 1 to disengage the mounting bolts 18 from the metal support frame 15 allows the light trough guide rail to be removed from the top of the processing table 1. Rotating the mounting bolts 43 to disengage the metal support frame 33 allows the metal support frame 33 to be disassembled. The metal support frame 33 and the light trough guide rail can be quickly installed and removed. The corresponding light trough guide rail and metal support frame 33 can be replaced and installed according to the specifications and models of the flexible light trough to be processed. Through simple installation and disassembly, the light trough cutting equipment can adapt to the processing needs of different models of flexible light troughs.

[0039] After the flexible light trough is fitted onto the outside of the light trough guide rail, until one end of the flexible light trough is fitted onto the outside of the corresponding metal support frame 33 of the light trough guide rail, the pre-installation of one flexible light trough is completed. Multiple flexible light troughs are installed in sequence. Then, the hydraulic cylinder 3 is controlled to work. The working stroke of the hydraulic cylinder 3 is controlled according to the specifications and model of the flexible light trough being processed. The hydraulic cylinder 3 drives multiple mounting frames 5 to move up and down through mounting frame 1 4. Multiple friction tubes 6 located at the top of the processing table 1 press against the upper surface of multiple flexible light troughs. Under the action of the one-way bearing 7, the friction tubes 6 can only rotate in one direction. At this time, the flexible light trough needs to overcome a large friction force to move to the left, and the friction force on the flexible light trough is smaller when moving to the right. After the hydraulic cylinder 3 finishes working, the installation of the flexible light trough is completed.

[0040] Subsequently, the dual-axis hydraulic cylinder 35 in the control cut support assembly operates, causing the two clamping components to synchronously approach the metal support frame 33. The dual-axis hydraulic cylinder 35 applies force to the clamping components through the damper 38. After the clamping components contact the flexible light groove on the outside of the metal support frame 33, the damper 38 contracts as the dual-axis hydraulic cylinder 35 operates, increasing the hydraulic pressure inside the damper 38. The hydraulic value detected by the hydraulic sensor 42 is fed back to the human-machine interface device. When the hydraulic value detected by the hydraulic sensor 42 reaches the preset value, the dual-axis hydraulic cylinder 35 is stopped, completing the clamping operation of the two clamping components on the flexible light groove. The cut support assembly supports and fixes one end of the flexible light groove. The damper 38 and the hydraulic sensor 42 ensure that the two clamping components clamp the flexible light groove to the outside of the metal support frame 33, and can stably control the clamping force, preventing the flexible light groove from deforming due to clamping and fixing during the cutting process.

[0041] Subsequently, the pneumatic cylinder 25 is activated, the fixed plate 26 moves to the right, multiple cutting support components move to the right, and the cutting support components pull the flexible light trough to the right. Under the action of multiple friction tubes 6 and the light trough guide rail, the flexible light trough is straightened to ensure cutting accuracy. The pneumatic cylinder 25 controls the working stroke according to the required cutting length of the flexible light trough. When the right end of the flexible light trough moves to the right by a preset length, the pneumatic cylinder 25 stops working. Then, the dual-axis hydraulic cylinder 35 in the cutting support component works to move the two clamping parts away from the metal support frame 33, allowing the metal support frame 33 to move inside the flexible light trough. The pneumatic cylinder 25 is activated to move the fixed plate 26 to the left, and the metal support frame 33 moves to the left inside the flexible light trough, causing the metal support frame 33 to move towards the right end of the light trough guide rail. When the metal support frame 33 reaches a preset distance from the right end of the light trough guide rail, the pneumatic cylinder 25 stops working. At this time, there is a cutting gap between the metal support frame 33 and the right end of the light trough guide rail, completing the flexible light trough cutting and positioning work.

[0042] Subsequently, the forward and reverse motors 10 in the control cutting structure are activated, and the position of the laser cutting device 13 is adjusted. The laser cutting device 13 cuts multiple flexible light slots, and the cut flexible light slots are supported by the metal support frame 33 near the cut, so as to avoid tilting of the flexible light slots during the cutting process, ensure that the cut is flat, and prevent the flexible light slots from tilting and causing the cut to re-adhere.

[0043] After multiple flexible light troughs are cut, the cut support assembly is controlled to clamp and fix the cut flexible light troughs. Then, the pneumatic cylinder 25 is controlled to move the cut support assembly to the right, causing the cut flexible light troughs to move to the right and leave from the bottom of the rightmost friction tube 6. Subsequently, the dual-axis hydraulic cylinder 35 in the cut support assembly is activated to move the two clamping parts away from the metal support frame 33. The metal support frame 33 can move inside the cut flexible light troughs. The pneumatic cylinder 25 is controlled to move the fixing plate 26 to the left, which is blocked by the multiple friction tubes 6 densely arranged on the right side and disengages from the metal support frame 33. When the metal support frame 33 returns to its initial position, that is, when the left end of the metal support frame 33 contacts the right end of the metal support frame 21 in the light trough guide rail, the electromagnet 28 moves to the bottom of the metal support frame 21. The electromagnet 28 is activated and fixed to the bottom of the metal support frame 21 by magnetic attraction. The metal support frame 33 moves synchronously with the metal support frame 21. With the activation of the pneumatic cylinder 25, the metal support frame 33 moves into the flexible light trough.

[0044] Then, the pneumatic cylinder 25 operates, and the cutting support assembly clamps and fixes one end of the flexible light trough. Subsequently, the pneumatic cylinder 25 operates, causing the fixing plate 26 to move to the right. The movement of the cutting support assembly drives one end of the flexible light trough to move to the right. During this process, after the metal support frame 21 resets, the electromagnet 28 stops working. The metal support frame 21 no longer moves synchronously with the metal support frame 33. Furthermore, the magnet 2, which is fixedly embedded on the top of the processing table 1, fixes the metal support frame 21 with magnetic force, preventing it from moving until subjected to a certain force. The magnet 2 and the electromagnet 28 are far apart and do not interact. Mutual interference, and the magnetic force applied by electromagnet 28 to metal support frame 21 is much greater than that applied by magnet 2 to metal support frame 21; after completing the flexible light trough cutting and positioning work, the flexible light trough is cut again. Through the cooperation of structures such as retractable light trough guide rail, magnet 2, cut support assembly, and multiple friction tubes 6, the loading, unloading, and cutting length positioning of the flexible light trough can be completed automatically. During the cutting process of the flexible light trough, the two sides of the cut are supported by metal support frame 33 and metal support frame 21 respectively, avoiding deformation due to force during the cutting process of the flexible light trough.

[0045] In summary, the dual-axis hydraulic cylinder 35 in the cut support assembly drives the fixed plate 6 39 and the clamping plate 40 close to the metal support frame 3 33 via the transmission slide rod 37. At the same time, the damper 38 flexibly transmits the force to the clamping plate 40. The hydraulic sensor 42 monitors the hydraulic pressure inside the damper 38 in real time. When the hydraulic pressure reaches the preset threshold, the dual-axis hydraulic cylinder 35 automatically stops working. This ensures that the two clamping plates 40 clamp the flexible light trough to the outside of the metal support frame 3 33, and also stably controls the clamping force. This fundamentally avoids the local dents or cross-sectional deformation of the flexible light trough caused by over-clamping in traditional rigid clamps, and ensures the assembly accuracy of the light trough after cutting.

[0046] After the cutting and positioning are completed, a cutting gap is left between the metal support frame 33 and the right end of the light trough guide rail, i.e., the metal support frame 21. When the laser cutting equipment 13 cuts, the cut flexible light trough is supported by the metal support frame 33 near the cut. At the same time, the metal support frame 21 is connected to the metal support frame 15 through the support plate 20, forming a continuous support on the other side of the cut. The double-sided support effectively offsets the cutting thermal stress and mechanical vibration, avoids the flexible material from tilting due to local suspension, ensures the verticality of the section, and avoids the flexible light trough tilting movement causing the cut to re-adhere.

[0047] A one-way bearing 7 is fixedly embedded on the outer side of the mounting bracket 25. The inner wall of the friction tube 6 is fixedly connected to the outer ring of the one-way bearing 7, so that the friction tube 6 can only rotate in one direction. When the pneumatic cylinder 25 drives the cutting support assembly to move to the right and straighten the lamp groove, the friction force on the flexible lamp groove moving to the right is minimal. When the lamp groove is retracted to the left by the elastic restoring force, the friction tube 6 locks and generates a large frictional resistance. The one-way damping characteristic effectively prevents the cut from re-fitting due to its own elastic contraction after the lamp groove is cut, ensuring that the cutting and separation are thorough.

[0048] The pneumatic cylinder 25 drives the fixed bending rod 29, fixed plate 30 and fixed plate 4 31 to move to the right as a whole through the fixed plate 1 26. At the same time, the dual-axis hydraulic cylinder 35 drives the clamping plate 40 to clamp the end of the flexible lamp groove, so as to achieve precise straightening and fixed-length feeding, and avoid the bending of the flexible lamp groove from affecting the cutting accuracy.

[0049] Multiple guide grooves 19 are opened on the outer side of the metal support frame 15. The support plate 20 is inserted into the guide groove 19 and one end is fixedly connected to the metal support frame 21. Limiting grooves 22 are opened on both sides inside the metal support frame 15. The two ends of the crossbar 23 pass through the limiting groove 22 and are fixed to the support plate 20 on the same side. When the metal support frame 21 moves to the right with the cutting support assembly, the support plate 20 slides out along the guide groove 19. Multiple support plates 20 form a guide channel between the metal support frame 21 and the metal support frame 15, always supporting the bottom of the lamp trough and preventing the suspended section of the lamp trough from sagging due to gravity, which would affect the cutting accuracy.

[0050] An electromagnet 28 is fixed to the top of the fixed plate 27, corresponding one-to-one with the metal support frame 33; a magnet 2 is fixedly embedded on the top of the processing table 1. During the reset phase, the electromagnet 28 is energized to attract the metal support frame 21, causing it to move to the left synchronously with the metal support frame 33; after the reset is completed, the electromagnet 28 is de-energized, and the magnet 2 uses permanent magnetic force to fix the metal support frame 21 in the initial position until the cutting support assembly applies sufficient tension to overcome the magnetic force, realizing the instantaneous switching between the two modes of "synchronous movement" and "independent fixation" between the components, which is for automatic cyclic positioning.

[0051] A single unit can cover the cutting needs of flexible light troughs of various specifications. Enterprises do not need to configure independent production lines for each model. The number of equipment purchased and the space occupied are greatly reduced. The double-sided support of the cut and the unidirectional friction traction respectively ensure the flatness of the cross-section and the separation of the cut. The combination of the three makes the cutting defect rate significantly lower than that of traditional equipment, directly saving the cost of raw materials for flexible light troughs. The fully automatic feeding, positioning, cutting and unloading cycle, combined with the non-contact high-speed processing of the laser cutting equipment 13, shortens the single-piece processing cycle compared with traditional manual auxiliary equipment and significantly improves the production capacity.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
