Description

Technical Field

[0001] The present invention relates to the field of photovoltaic component manufacturing equipment, and in particular to a solar photovoltaic panel frame stamping module and a stamping method thereof. Background Art

[0002] The photovoltaic module frame is a key structure for fixing and sealing solar cell modules, which directly affects the service life and installation reliability of the module. Aluminum alloy frames dominate the market due to their excellent processing performance and long-term life verification. However, as photovoltaic modules develop towards high power and thinness, the requirements for frame processing accuracy are becoming increasingly stringent, especially hole position accuracy, straightness control and surface integrity have become core indicators of industry quality control. In the field of frame processing equipment, the positioning accuracy and operational stability of the stamping module are key factors in determining product quality. Chinese Patent Publication No. CN119747493A discloses an extrusion die for aluminum frames of photovoltaic modules. This patent improves the positioning accuracy of the die and punch through the combined structure of positioning pins and abutment rods. The flexible rods and abutment blocks are used to facilitate mold disassembly, representing a significant advancement in the field of extrusion molding. However, this technical solution still has the following limitations: First, the design is mainly based on the extrusion process, but it does not solve the problem of horizontal displacement of the photovoltaic panel frame profile caused by high-speed movement during the stamping process. Therefore, there is still a certain dimensional deviation in actual production. Second, the lack of surface protection mechanism leads to a high rate of oxide film damage due to the rigid contact between the fixed mold and the photovoltaic panel frame profile; Therefore, the development of a stamping module that combines high-precision positioning, all-round surface protection and rapid maintenance functions has become a key technical breakthrough direction for solving the current pain points of photovoltaic frame processing. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art.

[0004] The present application provides a solar photovoltaic panel frame stamping module, which includes a frame, several stamping modules, a fastening device and an equipment push plate, and also includes a base plate, which is fixed on the frame. The stamping module includes a mounting plate, a fixed die, a movable die, and a punch. The mounting plate is mounted on the base plate through several fasteners, and the equipment push plate is connected to the movable die through a connecting plate. The fastening device is used to fix the top surface, side surfaces and ends of the photovoltaic panel frame placed on the movable die.

[0005] The fastening device includes a connecting rod, a top pressure rod, a side pressure rod and a clamping column. The connecting rod is rotatably installed on the top of the frame.

Loading and positioning: The photovoltaic panel frame profile blank that has undergone anodizing and coating surface treatment is clamped and placed on the movable mold by the loading and unloading manipulator, so that the photovoltaic panel frame profile blank is aligned with the fixed mold. The pushing cylinder pushes the photovoltaic panel frame profile blank to the stop block to achieve end positioning; S3. Tightening and clamping: External power drives the connecting rod to rotate, driving the top pressure rod and the side pressure rod to press down. The top rod presses the top surface of the photovoltaic panel frame profile blank, and the tightening column on the side pressure rod presses the photovoltaic panel frame profile blank toward the fixed mold, thereby fixing the side and top surfaces of the photovoltaic panel frame profile blank to prevent horizontal displacement during stamping; S4, stamping processing: The equipment push plate drives the movable die to move toward the fixed die through the connecting plate, and the punch on the movable die stamps the photovoltaic panel frame profile blank; S5. Unloading and conveying: After the stamping is completed, the movable mold is reset, and the connecting rod rotates in the opposite direction to loosen the top pressure rod and the side pressure rod. The loading and unloading manipulator clamps the stamped frame part out of the mold and places it on the conveyor belt, completing a stamping cycle.

[0014] The beneficial effects of the present invention are as follows: Positioning accuracy is significantly improved: a triple fixing mechanism is adopted, including end positioning of the push cylinder and the stopper, vertical pressing of the top pressure rod, and horizontal pressing of the side pressure rod, to reduce positioning deviation of the photovoltaic panel frame profile; Comprehensive improvement in surface quality: Through the guiding design of the punch lubrication device and the synergistic effect of the oil storage felt and the oil scraper groove, the punch is lubricated and wear is reduced, while the lubricating oil contamination rate is reduced; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0018] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0019] The solar photovoltaic panel frame stamping module and the stamping method thereof provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0020] Example 1: An embodiment of the present application provides a solar photovoltaic panel frame stamping module, including a frame 1, several stamping modules 2, a fastening device 3 and an equipment push plate 4, and is characterized in that it also includes a base plate 5, which is fixed on the frame 1, and the stamping module 2 includes a mounting plate 21, a fixed mold 22, a movable mold 23, and a punch 25. The mounting plate 21 is mounted on the base plate 5 through several fasteners 6, and the equipment push plate 4 is connected to the movable mold 23 through a connecting plate. The fastening device 3 is used to fix the top surface, side surfaces and ends of the photovoltaic panel frame placed on the movable mold 23.

[0021] The fastening device 3 includes a connecting rod 31, a top pressure rod 32, a side pressure rod 33 and a clamping column 34. The connecting rod 31 is rotatably mounted on the top of the frame 1. The top pressure rod 32 and the side pressure rod 33 are both fixed on the connecting rod 31. The clamping column 34 is fixed on the bottom surface of the side pressure rod 33 away from one end of the connecting rod 31. The connecting rod 31 is driven to rotate by external power.

[0022] The fastening device 3 further includes a pushing cylinder 35 and a stopper 36 . The pushing cylinder 35 and the stopper 36 are respectively fixed at both ends of the frame 1 and are located in the same straight line as the fixed mold 22 .

[0023] like Figures 1 to 3 As shown, due to the adoption of the above-mentioned structure, the frame 1 provides stable support for the entire stamping module 2 through the base plate 5, and the mounting plate 21 is fixed to the base plate 5 by fasteners 6 to ensure that the fixed die 22 is firmly positioned; the equipment push plate 4 drives the movable die 23 to move through the connecting plate to realize the coordinated stamping of the punch 25 and the fixed die 22, and the fastening device 3 ensures the positioning accuracy of the photovoltaic panel frame profile through a multi-dimensional fixing mechanism: the pushing cylinder 35 cooperates with the block 36 to achieve precise alignment of the ends of the photovoltaic panel frame profile, the connecting rod 31 rotates to drive the top pressure rod 32 to press the top surface of the photovoltaic panel frame profile, and the side pressure rod 33 presses the photovoltaic panel frame profile to the fixed die 22 through the clamping column 34. The triple fixation avoids horizontal or vertical displacement of the photovoltaic panel frame profile during stamping, and solves the deformation and dimensional deviation problems caused by positioning deviation in traditional processes.

[0024] Example 2: In this embodiment, in addition to the structural features of the aforementioned embodiments, the punching module 2 further includes a punch lubricating device 24 for applying lubricating oil to the surface of the punch 25 .

[0025] In this embodiment of the present application, the punch lubrication device 24 includes a punch guide plate 241, a guide hole 244, a lubrication groove 242 and an oil storage felt 245. The punch guide plate 241 is floatingly mounted on the movable mold 23 through a sliding rod. The guide hole 244 and the lubrication groove 242 are both opened on the punch guide plate 241 and intersect each other vertically. The oil scraping groove 243 is opened on the punch guide plate 241 and intersects with the guide hole 244. The oil storage felt 245 is arranged in the lubrication groove 242. The punch 25 is fixed on the movable mold 23 and penetrates the guide hole 244 and the oil storage felt 245.

[0026] In this embodiment of the present application, the punch lubricating device 24 further includes an oil scraping groove 243 . The oil scraping groove 243 is provided on the punch guide plate 241 and intersects with the guide hole 244 .

[0027] In this embodiment of the present application, a wedge-shaped oil scraping tongue 246 is provided on the front side of the oil scraping groove 243 .

[0028] In this embodiment of the present application, the distance between the side surface of the wedge-shaped oil scraping tongue 246 and the surface of the punch 25 is 2-3 mm.

[0029] In this embodiment of the present application, oil guide holes 247 are provided at both ends of the oil scraping groove 243 .

[0030] A stamping method is also disclosed, comprising the following steps: S1. Die debugging: calibrate the uniformity of the gap around the punch 25 and the guide hole 244 to ensure that the edge of the cut is smooth during punching, avoiding local burrs, jamming and die deformation; S2. Loading and positioning: The photovoltaic panel frame profile blank after anodizing and coating surface treatment is clamped and placed on the movable mold 23 by the loading and unloading manipulator, so that the photovoltaic panel frame profile blank is aligned with the fixed mold 22. The pushing cylinder 35 pushes the photovoltaic panel frame profile blank to the stopper 36 to achieve end positioning; S3. Tightening and clamping: External power drives the connecting rod 31 to rotate, driving the top pressure rod 32 and the side pressure rod 33 to press down. The top rod presses the top surface of the photovoltaic panel frame profile blank. The tightening column 34 on the side pressure rod 33 presses the photovoltaic panel frame profile blank toward the fixed mold 22 to fix the side and top surfaces of the photovoltaic panel frame profile blank to prevent horizontal displacement during stamping. S4, stamping process: the equipment push plate 4 drives the movable die 23 to move toward the fixed die 22 through the connecting plate, and the punch 25 on the movable die 23 stamps the photovoltaic panel frame profile blank; S5, unloading and conveying: After the stamping is completed, the movable mold 23 is reset, and the connecting rod 31 rotates in the opposite direction to loosen the top pressure rod 32 and the side pressure rod 33. The loading and unloading manipulator clamps the stamped frame part out of the mold and places it on the conveyor belt, completing a stamping cycle; Among them, in step S4, the oil storage felt 245 on the punch guide plate 241 evenly applies lubricating oil to the surface of the punch 25, and at the same time, the oil scraping groove 423 scrapes off the excess lubricating oil between the punch 25 and the guide hole 244 and discharges it from the mold to avoid contaminating the surface of the photovoltaic panel frame.

[0031] like Figures 1 to 3 As shown, due to the adoption of the above-mentioned structure, the punch lubrication device 24 adapts to the movement trajectory of the punch 25 through a floating design - the punch guide plate 241 moves synchronously with the movable die 23 with the help of the slide rod, ensuring that the guide hole 244 always forms a stable guide for the punch 25 passing therethrough; the oil storage felt 245 in the lubrication groove 242 is in continuous contact with the surface of the punch 25, and lubricating oil is evenly applied during the reciprocating punching process of the punch 25, reducing the friction loss between the punch 25 and the guide hole 244. The design of the guide hole 244 and the lubrication groove 242 intersecting vertically not only ensures the straightness of the movement of the punch 25, but also enables the lubricating oil to be evenly distributed along the surface of the punch 25, further improving the flatness of the punching cut.

[0032] The oil scraping groove 243 is provided on the punch guide plate 421 and intersects with the guide hole 244. The setting of 43 enables the excess lubrication on the surface of the punch 25 to be scraped off by the wedge-shaped oil guide tongue 246 on the oil scraping groove 243 and discharged out of the mold through the oil guide hole 247, thereby preventing the lubricating oil from penetrating through the gap between the punch 25 and the guide hole 244 to the front end of the punch 25 and contaminating the surface of the photovoltaic panel frame during the long-term continuous reciprocating punching process of the punch 25.

[0033] Example 3: In this embodiment, in addition to the structural features of the aforementioned embodiments, the fastener 6 includes a locking block 61, a locking groove 62, a locking plate 63, a lifting assembly 64, a locking groove 65 and a locking unit 66. The locking block 61 is fixed on the side wall of the mounting plate 21, and the locking groove 62 passes through the locking block 61 up and down. The bottom of the lifting assembly 64 is fixed to the base plate 5, the middle is penetrated in the base plate 5, and the top is fixed to the locking plate 63 and can be inserted into the locking groove 62. The cross-sections of the locking plate 63 and the locking groove 62 are both long strips. The lock groove 65 is opened on the side of the mounting plate 21, and the locking unit 66 is floatingly installed on the locking plate 63 for plugging with the lock groove 65.

[0034] In this embodiment of the present application, a through slot 67 is defined at one end of the latching slot 62 for allowing the protruding end of the latching unit 66 to pass through when the latching plate 63 passes through the latching slot 62 .

[0035] like Figures 1 to 3As shown, due to the adoption of the above structure, the fastener 6 realizes a fast and stable connection between the mounting plate 21 and the base plate 5 through mechanical locking - when the locking block 61 descends, the locking plate 63 passes through the locking groove 62 of the locking block 61 and rises above the locking block 61. When the locking plate 63 is rotated, the lifting assembly 64 drives the locking plate 63 to descend, and the long strip of locking plate 63 rotates to be perpendicular to the locking groove 62, and at the same time, it is tightly matched with the top surface of the locking block 61 to limit the vertical displacement of the mounting plate 21; when the locking plate 63 is in place, the locking unit 66 is released from the locking plate 63 floats out and inserts into the locking slot 65 of the mounting plate 21, ensuring that the locking plate 63 does not loosen under the vibration of stamping. The design of the locking slot 62 and the through slot 67 provides movement space for the locking unit 66 to ensure smooth locking action. A depression adapted to the shape of the locking block 61 is provided on the bottom plate 5 to limit the front and back and left and right directions of the mounting plate 21. This structure solves the problem of cumbersome disassembly of traditional fasteners 6, facilitates the rapid replacement and debugging of the stamping module 2, adapts to the flexible combination requirements of modular molds, and improves the efficiency of mold maintenance and upgrading.

[0036] Example 4: In this embodiment, in addition to the structural features of the aforementioned embodiments, the latch unit 66 includes a latch slot 661, an insert block 662, a transverse slot 663, a blocking block 664 and a thrust spring 665. The latch slot 661 passes through the longer ends of the latch plate 63 on the left and right, the insert block 662 is inserted in the latch slot 661, and the transverse slot 663 passes through the middle of the insert block 662 from top to bottom. The blocking block 664 is fixed in the latch slot 661 and slides with the transverse slot 663. The thrust spring 665 is arranged in the transverse slot 663, and its two ends abut against the ends of the transverse slot 663 and the blocking block 664, so as to provide thrust for the insert block 662 to be inserted into the lock slot 65.

[0037] In this embodiment of the present application, the plug-in block 662 includes a plug-in section 6621 and a toggle section 6622. One end of the plug-in section 6621 is a plug-in end for plugging into the lock slot 65, and the other end is fixedly connected to the toggle section 6622. The lock slot 661 is open away from the top of the plug-in end for accommodating the toggle section 6622.

[0038] like Figures 4 to 7 As shown, due to the adoption of the above structure, the latch unit 66 realizes automatic locking and convenient unlocking through elastic drive and mechanical limit - the thrust spring 665 continuously applies thrust to the plug-in block 662 in the transverse groove 663, so that the plug-in section 6621 always has a tendency to insert into the lock groove 65. When the locking plate 63 is in place, the toggle section 6622 of the plug-in block 662 is pulled to retract its plug-in end into the latch groove 661, and then the plug-in block 662 is rotated. While the plug-in block 662 rotates, it descends and presses the top surface of the locking block 61, and the latch groove 661 is aligned with the latch groove 661. The plug-in block 662 is released, and under the push of the thrust spring 665, the plug-in section 6621 automatically snaps into the lock groove 65 to complete the locking. The blocking block 664 slides in cooperation with the transverse groove 65 to limit the movement trajectory of the plug-in block 662 and prevent it from deflecting. When unlocking is required, the plug-in block 662 is pulled by the toggle section 6622 to compress the thrust spring 665, so that the plug-in section 6621 is disengaged from the lock groove 65, which is easy to operate.

[0039] This structure not only ensures the reliability of the locking state and prevents the plug-in block 662 from loosening during the stamping process, but also simplifies the unlocking steps and further improves the efficiency of disassembly and assembly of the mold module.

[0040] Example 5: In this embodiment, in addition to the structural features of the aforementioned embodiments, the lifting assembly 64 includes a fixed rod 641, a lifting cylinder 642, a spiral groove 643, a transmission block 644, a buffer spring 645 and a convex ring 646. The fixed rod 641 is fixed on the top surface of the base plate 5, the lifting cylinder 642 is sleeved on the top of the fixed rod 641, and a convex ring 646 is provided at the bottom of its outer peripheral wall. The spiral groove 643 is opened on the inner wall of the lifting cylinder 642, the transmission block 644 is fixed on the outer wall of the fixed rod 641, and it slides with the spiral groove 643. The buffer spring 645 is sleeved on the outside of the fixed rod 641, and its top and bottom ends are respectively abutted against the bottom end of the lifting cylinder 642 and the top surface of the top plate.

[0041] like Figures 4 to 7 As shown, due to the adoption of the above-mentioned structure, the lifting component 64 realizes the smooth lifting and rotation pre-tightening of the locking plate 63 through spiral transmission and elastic buffering - when the lifting cylinder 642 rises, the transmission block 644 on the fixed rod 641 slides along the spiral groove 643 on the inner wall of the lifting cylinder 642, forcing the lifting cylinder 642 to rise and rotate, driving the locking plate 63 to rotate synchronously, so that the locking plate 63 and the locking groove 62 form a rotational lock, thereby enhancing the connection stability; the buffer spring 645 provides elastic support during the placement and lifting of the mounting plate 21, absorbs the lifting impact, and avoids structural damage caused by hard contact. At the same time, it provides continuous pre-tightening force after the locking plate 63 is in place to prevent vibration loosening. The convex ring 646 is used to carry the locking block 61 to ensure structural safety. This design enables the lifting action to have both power transmission and locking functions, thereby improving the overall stability and service life of the fastener 6.
