Description

Technical Field

[0001] This invention relates to the field of profile cutting equipment technology, and in particular to a bevel cutting device for the end of a profile. Background Technology

[0002] Solar energy has a wide variety of applications, among which photovoltaic (PV) power generation is one of the most mature and widely used core technologies. This technology captures and absorbs solar energy through solar panels (PV modules), and uses the photoelectric conversion properties of semiconductor materials to directly convert clean solar energy into usable electrical energy. PV is short for solar photovoltaic power generation system, which is essentially an energy conversion system based on the photovoltaic effect. This system utilizes the photovoltaic effect generated by the semiconductor materials of solar cells (such as monocrystalline silicon, polycrystalline silicon, perovskite, etc.) under sunlight to achieve the direct conversion of light energy into electrical energy, with no mechanical movement and no pollutant emissions throughout the entire process.

[0003] The solar photovoltaic bracket, as the core load-bearing structure supporting the photovoltaic modules, has its frame made of profile material.

[0004] In Chinese invention patent application number 202211472134.4, a photovoltaic module frame profile production line is proposed. However, this patent has the following drawbacks: the core execution component of the cutting machine used in this patent is a circular saw blade, which works by vertically cutting along the vertical direction of the profile. This structural design can only achieve flat cutting at the end of the profile, and cannot meet the process requirements for bevel cutting in the actual assembly process of photovoltaic module frame profiles. It is necessary to configure special bevel cutting equipment or add a secondary manual processing step, which not only reduces production efficiency, but also increases equipment investment and labor costs.

[0005] Furthermore, while some existing cutting equipment possesses beveling capabilities, its practical application is hampered by factors such as saw blade stroke and profile clamping stability, preventing complete profile severance. After beveling, two adjacent profiles retain a partial connection. To separate the profiles, additional operators are required to manually disconnect the incompletely cut sections, severely impacting the automation continuity of the production line and posing safety hazards due to manual operation. Summary of the Invention

[0006] The main technical problem to be solved by the present invention is to provide a bevel cutting device for profile ends, which can complete the precise positioning and complete bevel cutting of the profile in one go, completely eliminating the cumbersome process of additional configuration of special bevel cutting equipment, manual secondary processing or manual breaking of profiles in traditional production, and greatly reducing the investment in equipment purchase cost and labor cost.

The upper cutting blade is movably installed above the lower cutting die through a guide positioning mechanism, and the lower cutting die is fixedly assembled to the bottom of the inner side of the cutting frame.

[0008] The following are further optimizations of the above technical solution by the present invention: The cutting blade includes a cutting blade part and a cutting blade part integrally formed. The side of the cutting blade part in the X-axis direction is triangular, and its width gradually decreases from top to bottom. The side of the cutting blade part in the Y-axis direction is triangular, and its width gradually decreases from top to bottom.

[0009] Further optimization: The top of the lower cutting die has a material passage cavity running through it along the X-axis, and the width of the material passage cavity is adapted to the width of the profile. The profile passes through the lower cutting die through the material passage cavity. Cutting slots are provided on both sides of the material passage cavity. The shape and size of the cutting slots are adapted to the upper cutting blade to ensure the fitting accuracy of the two.

[0013] Further optimization: The cutting platform is slidably mounted on the frame along the X-axis direction, and an X-axis cylinder is fixedly mounted on the frame along the X-axis direction. The telescopic rod of the X-axis cylinder is connected to the cutting platform.

[0014] Further optimization: The positioning device includes a fixed frame that is fixedly installed on the bottom inner side of the cutting frame. A positioning pin is slidably installed on the upper end of the fixed frame along the Z-axis direction. The positioning pin is driven to move by a positioning drive cylinder. The cylinder body of the positioning drive cylinder is fixedly installed on the fixed frame.

[0015] Further optimization: An L-shaped support is fixedly installed on the cutting platform, and a position sensing element is fixedly installed on the upper end of the L-shaped support.

[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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1-4 As shown, a bevel cutting device for the end of a profile includes a cutting platform 1.

[0023] In this embodiment, the cutting platform 1, as the core support and working unit of the profile end bevel cutting equipment, is fixedly set at the downstream end of the photovoltaic module frame profile forming production line, forming a seamless automated production process with the upstream profile forming unit and fixed length conveying mechanism.

[0024] The layout of the cutting platform 1 fully considers the continuous operation requirements of the production line. The profiles to be formed, straightened and surface treated can be directly transported to the designated working area of ​​the cutting platform 1 through the upstream conveying mechanism without the need for additional manual transfer or intermediate buffering.

[0025] Furthermore, a finished product conveyor line can be installed at the downstream end of the cutting platform 1. This conveyor line can adopt a roller conveyor structure or a belt conveyor structure. Its conveying speed is precisely matched with the working rhythm of the cutting platform 1, so that the finished profile can be smoothly and efficiently conveyed away from the cutting operation area immediately after the profile has completed the bevel cutting operation. This avoids the accumulation of finished profiles on the cutting platform 1 and ensures the continuous operation of the cutting process.

[0026] Preferably, the cutting platform 1 is provided with, in sequence along the profile moving direction: a position sensing element 3 for detecting the profile position, a positioning device for positioning the profile, and a cutting device for cutting the profile.

[0027] In this embodiment, the position sensing element 3 is preferably a laser displacement sensor that is technically mature and readily available in the market. Specifically, the optoNCDT1420 laser displacement sensor from Miyi (Beijing) Test Technology Co., Ltd. can be used.

[0028] The profiles that have been processed by the upstream forming process have several sets of hole structures on their top end face according to the preset process requirements. The hole structure consists of position detection round holes, positioning elongated holes and cutting grooves arranged in sequence.

[0029] The core detection object of the position sensing element 3 is the position detection hole on the top of the profile. Its working principle is to emit a laser beam and receive the reflected signal to identify the position of the position detection hole in real time, thereby providing a precise positioning trigger signal for the subsequent bevel cutting process.

[0030] Preferably, the cutting device includes a cutting frame 4 fixed to the top of the cutting platform 1. An upper cutting blade 5 and a lower cutting die 6 are arranged opposite each other on the inner side of the cutting frame 4, and the two are fitted together. The upper cutting blade 5 is movably installed above the lower cutting die 6 through a guide positioning mechanism, and the lower cutting die 6 is fixedly assembled to the bottom of the inner side of the cutting frame 4.

[0031] In this embodiment, the cutting platform 1 adopts a split-type hierarchical structure design, mainly consisting of a horizontally set base plate and a mounting plate arranged parallel above the base plate.

[0032] A vertical screw extending along the Z-axis is fixed to each of the four corners of the base plate. Correspondingly, four elongated holes extending along the Y-axis are opened at the four top corners of the mounting plate. Each vertical screw passes through the corresponding elongated hole to form an adjustable connection structure between the base plate and the mounting plate.

[0033] Each vertical screw is threaded with two limit nuts. The two limit nuts clamp and position the mounting plate from the top and bottom respectively. The limit nut at the bottom of the mounting plate supports the mounting plate, while the limit nut at the top of the mounting plate is tightened to fix and lock the mounting plate in place.

[0034] Operators can easily adjust the vertical height of the mounting plate by rotating the upper and lower limit nuts to match the cutting reference of profiles with different cross-sectional heights. At the same time, the horizontal position of the mounting plate can be finely adjusted by using the length allowance of the long slot along the Y-axis, thereby ensuring the precise alignment of the cutting actuator with the profile and greatly improving the equipment's adaptability and cutting accuracy for profiles of different specifications and sizes.

[0035] Preferably, the cutting blade 5 includes an integrally formed cutting blade part 501 and a cutting blade part 502. The cutting blade part 501 has a triangular side in the X-axis direction, and its width gradually decreases from top to bottom. The cutting blade part 502 has a triangular side in the Y-axis direction, and its width gradually decreases from top to bottom.

[0036] In this embodiment, the cutting blade 501 extends in the same direction as the profile conveying direction, and its blade structure is specifically designed with two symmetrically distributed beveled blades machined at the bottom.

[0037] When the cutting operation is started, the cutting blade 501 feeds downward in the vertical direction. Through the precise contact and cutting action between the two beveled blades and the profile surface, the bevel processing operation that meets the assembly requirements can be completed at the end of the profile in one go, effectively ensuring the angle accuracy and surface flatness of the bevel.

[0038] In addition, the extension direction of the cutting edge on the cutting blade 502 is perpendicular to the conveying direction of the profile, and two beveled cutting edges are also provided at the bottom of the cutting edge.

[0039] After the cutting blade 501 completes the bevel cutting process, the cutting blade 502 moves downward in the vertical direction and acts on the designated position where the bevel has been processed in the direction of the bevel, so as to achieve complete cutting and separation of the profile. This solves the problem that traditional cutting equipment requires manual assistance to break the profile due to incomplete cutting. It ensures that the end of the cut profile can meet the assembly requirements and achieves complete separation between the two profiles.

[0040] Preferably, the top of the cutting die 6 has a material passage cavity 7 extending through it along the X-axis, and the width of the material passage cavity 7 is adapted to the width of the profile, through which the profile passes through the cutting die 6.

[0041] In this embodiment, the material passage 7 adopts a fully through-type structure design along the conveying direction of the profile. Its cavity cross-sectional dimensions are adapted to the outer contour of the profile to be processed, which can provide stable guiding constraints for the profile and avoid positional displacement or deformation under the action of cutting force. This ensures that the profile passes smoothly without significant shaking during the conveying process, thereby improving the stability and safety of the cutting process.

[0042] Preferably, cutting slots 8 are provided on both sides of the material passage cavity 7. The shape and size of the cutting slots 8 are adapted to the cutting blade 5 to ensure the fitting accuracy of the two.

[0043] Meanwhile, a cavity for accommodating the cutting blade 502 is formed through the middle position of the bottom of the cutting groove 8.

[0044] In this embodiment, the cutting groove 8, as a key supporting structure of the cutting mechanism, undertakes a dual core function. On the one hand, the groove size, depth and angle of the cutting groove 8 are precisely matched with the blade profile of the upper cutting blade 5, achieving precise engagement with the upper cutting blade 5 and ensuring the stability of cutting.

[0045] During the cutting operation, when the upper cutting tool 5 feeds downward to complete the cutting action, the cutting edge can be completely embedded inside the cutting groove 8. This avoids hard contact between the cutting edge and the cutting platform 1, effectively protecting the cutting edge of the upper cutting tool 5 from damage and extending the tool's service life. At the same time, it limits the movement of the upper cutting tool 5 in the X-axis direction during the cutting process, ensuring the consistency of the bevel cutting angle and eliminating the problem of deviation in cutting accuracy caused by the movement of the upper cutting tool 5.

[0046] On the other hand, the setting of the cutting slot 8 provides a channel for the rapid removal of waste generated after cutting, and the waste can be cleaned up without manual intervention, thereby realizing automated chip removal, reducing the cost of manual cleaning and the potential safety hazards during the cleaning process. At the same time, it also solves the problem of waste accumulating in the working area and affecting subsequent cutting operations in traditional cutting equipment, and greatly improves the continuous operation efficiency of the production line.

[0047] Preferably, the guiding and positioning mechanism includes a Z-axis adjustment component and a Y-axis adjustment component. The Z-axis adjustment component is used to drive the upper cutting blade 5 to slide along the Z-axis direction, and the Y-axis adjustment component is used to drive the upper cutting blade 5 to slide along the Z-axis direction.

[0048] In this embodiment, the Z-axis adjustment component is configured to drive the upper cutting blade 5 to perform precise lifting and lowering movements along the Z-axis, thereby achieving two key action stages: cutting feed and resetting of the upper cutting blade 5. When the cutting operation starts, the Z-axis adjustment component drives the upper cutting blade 5 to feed downward along the Z-axis, so that the cutting edge of the upper cutting blade 5 precisely acts on the surface of the profile to complete the bevel cutting and complete cut-off operation. After the cutting process is completed, the Z-axis adjustment component drives the upper cutting blade 5 to reset upward along the Z-axis, returning to the initial standby position, and preparing for subsequent cutting operations.

[0049] The Y-axis adjustment component is designed to automatically clean up waste materials. By driving the upper cutting blade 5 to reciprocate along the Y-axis, the waste material remaining in the material passage 7 after cutting can be pushed to the cutting slot 8. Under the driving force of the Y-axis adjustment component, the waste material can quickly slide down along the through channel of the cutting slot 8 and leave the material passage 7. This fundamentally avoids the situation in traditional cutting equipment where waste material accumulation blocks the material passage, interfering with the subsequent material conveying and cutting operations. This significantly improves the continuity and automation level of the cutting process.

[0050] Preferably, the Z-axis adjustment assembly includes a Z-axis slide block 9 slidably mounted on the cutting frame 4 along the Z-axis direction. A Z-axis drive cylinder 10 is connected between the Z-axis slide block 9 and the cutting frame 4. The cylinder body of the Z-axis drive cylinder 10 is fixedly mounted on the cutting frame 4, and its piston rod is connected to the Z-axis slide block 9.

[0051] Preferably, the Y-axis adjustment assembly includes a Y-axis slide 11 that is slidably mounted on the Z-axis slide 9 along the Y-axis direction. A Y-axis drive cylinder 12 is connected between the Y-axis slide 11 and the Z-axis slide 9. The cylinder body of the Y-axis drive cylinder 12 is fixedly mounted on the Z-axis slide 9, and its piston rod is connected to the Y-axis slide 11.

[0052] Preferably, the cutting platform 1 is slidably mounted on the frame 2 along the X-axis direction, and an X-axis cylinder 13 is fixedly mounted on the frame 2 along the X-axis direction. The telescopic rod of the X-axis cylinder 13 is connected to the cutting platform 1.

[0053] Preferably, the positioning device includes a fixing frame 14 fixedly installed on the bottom inner side of the cutting frame 4, and a positioning pin 15 is slidably installed on the upper end of the fixing frame 14 along the Z-axis direction.

[0054] It should be noted that the positioning elongated hole at the top of the profile is a long strip structure. When the positioning pin 15 is initially inserted into the positioning elongated hole, it can only make contact with the inner wall of one end of the positioning elongated hole and cannot simultaneously achieve contact with the other end. It is necessary to drive the profile to continue to move a preset distance along the X-axis direction in order to make the positioning pin 15 make effective contact with both ends of the positioning elongated hole.

[0055] Based on the above structural characteristics, after the positioning pin 15 is inserted into the positioning elongated hole, the X-axis cylinder 13 can be controlled to release pressure, thus releasing the rigid limiting constraint of the cylinder on the cutting platform. At this time, the cutting platform 1 can move slightly synchronously with the profile along the X-axis until the positioning pin 15 and the inner walls of both ends of the positioning elongated hole are tightly fitted, completing the secondary precise positioning of the profile and ensuring that the cutting reference of the profile and the trajectory of the cutting blade 5 are completely coincident.

[0056] After the bevel cutting process is completed, compressed air is introduced into the X-axis cylinder 13 again to restore it to a rigid drive state, thereby driving the cutting platform 1 to accurately reset to the initial standby position along the X-axis direction, preparing for the processing of the next profile.

[0057] Preferably, the positioning pin 15 is moved by the positioning drive cylinder 16, and the cylinder body of the positioning drive cylinder 16 is fixedly mounted on the fixing frame 14.

[0058] In this embodiment, after the position sensing element 3 detects that the profile has been delivered to the correct position, the positioning device can be used to position the profile.

[0059] In this embodiment, the position of the positioning pin 15 corresponds to the position of the positioning elongated hole on the top of the profile. Through the tight cooperation between the positioning pin 15 and the positioning elongated hole, the profile is rigidly locked in the X-axis and Y-axis directions, which completely restricts the displacement of the profile and ensures the accuracy of subsequent cutting operations, thereby avoiding the occurrence of cut deviation due to profile movement during the cutting process.

[0060] Preferably, an L-shaped support frame 17 is fixedly installed on the cutting platform, and a position sensing element 3 is fixedly installed on the upper end of the L-shaped support frame 17.

[0061] Preferably, the position sensing element 3 extends along the Z-axis direction, and its sensing component faces directly downwards.

[0062] The equipment described in this invention performs bevel cutting on the formed photovoltaic module frame profile, achieving a fully automated integrated process of positioning, cutting, waste removal, and repositioning. The specific operation steps are as follows: S1. The profiles processed by the upstream forming production line are smoothly introduced into the working area of ​​this equipment along the preset conveying path under the drive of the matching conveying structure. During the conveying process, the profiles accurately pass through the material passage 7 set on the frame 2. S2. When the profile is continuously conveyed to the designated inspection station, the position sensing element 3 starts the inspection program, accurately identifies the preset position detection round hole on the top of the profile, and makes the positioning elongated hole on the profile move exactly below the positioning pin 15. S3. After the position is aligned, the positioning drive cylinder 16 receives a trigger signal, and its telescopic rod extends downward in the vertical direction, driving the positioning pin 15 fixed at the end to be precisely inserted into the corresponding positioning elongated hole of the profile. Then, the X-axis cylinder 13 is depressurized to release the rigid constraint on the cutting platform 1, so that the cutting platform 1 and the profile move synchronously and slightly along the X-axis until the positioning pin 15 is completely in contact with the inner wall of the positioning elongated hole, thereby aligning the pre-reserved cutting groove of the profile synchronously to the bottom of the cutting blade, realizing the precise matching of the positioning point and the cutting point. S4. After the profile is positioned for the second time, the Z-axis drive cylinder 10 starts synchronously. Its piston rod extends downward smoothly, driving the upper cutting blade 5 to move down synchronously along the Z-axis. The cutting blade part 501 and the cutting part 502 of the upper cutting blade 5 are then gradually inserted into the cutting groove of the profile, and the cutting operation is officially started. S5, Z-axis drive cylinder 10 drives the upper cutting blade 5 to continuously feed to the preset stroke position. At this time, the cutting blade 502 extends out of the bottom of the profile, ensuring that the cutting edge of the upper cutting blade 5 can complete the full-section cutting of the profile. After the S6 and Z-axis feed actions are completed, the Y-axis drive cylinder 12 is immediately started, driving the upper cutting blade 5 to perform a complete reciprocating translational movement along the Y-axis. During this process, the cutting blade 501, with its beveled edge and the limiting effect of the cutting groove 8, uses the precise shearing force formed between the blade and the inner wall of the groove to punch out a beveled edge that meets the process requirements at the end of the profile in one go, ensuring that the bevel angle is uniform and the cut surface is smooth and burr-free. S7. The cutting blade 502 acts synchronously on the corresponding connection position of the profile in a posture perpendicular to the profile conveying direction. With the help of the reciprocating driving force, the profile is completely cut off and separated, fundamentally eliminating the residual connection that exists in traditional cutting equipment. S8. After the cutting and separation action is completed, the upper cutting blade 5 is still in contact with the waste material. With the help of the regular plane on its side, a stable pushing force is formed to accurately push the two pieces of waste material generated during the cutting process into the corresponding cutting slots 8. The cutting slots 8 adopt a through-type structure design that is adapted to the contour of the waste material. After the waste material enters the cutting slots 8, it slides down to the preset waste material collection area under the action of gravity, realizing the automatic cleaning of waste material. S9. After the waste material is cleaned up, the Z-axis drive cylinder 10 drives the upper cutting blade 5 to move upward along the Z-axis direction and return to the initial standby position. At the same time, the X-axis cylinder 13 is controlled to ventilate, so that it drives the cutting platform 1 to move back to the origin position in the X-axis direction. S10, the telescopic rod of the positioning drive cylinder 16 retracts, causing the positioning pin 15 to be pulled out from the positioning long hole, completely releasing the positioning locking constraint on the profile. S11. The downstream conveyor structure starts up, smoothly outputting the finished profiles that have been cut at the bevel to the working area of ​​this equipment, and then into the subsequent sorting, palletizing or deep processing processes.
