Description

Technical Field

[0001] This invention relates to the field of frame punching technology, and more particularly to a horizontal side punching device used in the processing of photovoltaic aluminum alloy frames. Background Technology

[0002] Photovoltaic aluminum alloy frames are C-shaped or irregularly shaped hollow cross-section profiles made of aluminum alloy as the base material through processes such as hot extrusion molding, precision sawing, mechanical stamping, anodizing, and surface treatment. As a key structural component of photovoltaic modules, they are mainly used to wrap, clamp, fix, and seal the edges of photovoltaic modules, effectively protecting the corners of photovoltaic glass from impact damage, significantly improving the overall bending resistance, wind load resistance, and snow load resistance of photovoltaic modules, and providing standardized connection interfaces for subsequent power station installation. Excellent surface treatment gives them excellent weather resistance, corrosion resistance, and insulation properties. Through structural adhesives and sealants, they are tightly bonded to photovoltaic laminated modules, ensuring long-term reliable operation of the modules in complex outdoor environments.

[0003] Currently, conventional side-punching equipment generally uses a single-sided punch to directly form the photovoltaic aluminum alloy frame when punching holes. It does not design a matching internal support structure for the hollow thin-walled cavity structure of the frame. When punching the cavity area of ​​the frame, the lateral punching pressure cannot be effectively balanced and supported in the opposite direction. This results in a high concentration of local stress in the thin-walled area around the hole, which can easily cause plastic deformation problems such as inward collapse, edge warping, out-of-round hole shape, and burrs on the cross-section. This not only seriously affects the dimensional accuracy of the hole, the fit of the assembly and the regularity of the appearance, but also weakens the local structural strength of the frame and reduces the connection reliability and overall structural stability when tightening the bolts.

[0004] To address the aforementioned technical deficiencies, a solution is proposed that provides a reinforcing column to reliably support the cavity of the photovoltaic aluminum alloy frame. This avoids irregular deformation during punching and prevents the profile from concave during subsequent bolt tightening, thus ensuring the structural stability of the frame processing and assembly. Summary of the Invention

[0005] The purpose of this invention is to provide a horizontal side punching device for processing photovoltaic aluminum alloy frames, in order to solve the aforementioned technical defects.

[0006] The objective of this invention can be achieved through the following technical solution: a horizontal side punching device for processing photovoltaic aluminum alloy frames, comprising a feeding frame, a limiting baffle fixedly connected to one side of the top of the feeding frame, a U-shaped frame movably installed on the top of the feeding frame, and two sets of auxiliary clamping plates provided on the U-shaped frame, two sets of combined limiting baffles fixedly installed on opposite sides of the auxiliary clamping plates, a spring clamp for centering the photovoltaic aluminum alloy frame, punches for punching the photovoltaic aluminum alloy frame detachably installed on the auxiliary clamping plates, and reinforcing columns for self-floating position and assisting the punches in avoiding irregular deformation of the punching area of ​​the photovoltaic aluminum alloy frame provided between the punches.

[0007] Preferably, the spring clip is inclined, and a rubber block is fixedly connected to the free end of the spring clip.

[0008] Preferably, the punch has a stepped shaft structure, and the free end of the punch and the stepped surface are respectively provided with a punching conical surface and a stamping conical surface, and a plurality of punching and cutting blades are fixedly connected at equal intervals on the punching conical surface.

[0009] Preferably, the reinforcing column has through holes extending through both end faces, and the edges of the through holes have limiting cone surfaces that are compatible with the stamped conical surface.

[0010] Preferably, the material placement frame has an I-shaped limiting groove inside, and a limiting slide column adapted to it and driving the U-shaped frame to translate is slidably connected in the limiting groove. A lead screw threadedly connected to the limiting slide column is rotatably connected in the limiting groove, and a servo motor that drives the lead screw to rotate is installed on the material placement frame by bolts.

[0011] Preferably, the free end of the limiting slide column is fixedly connected to a connecting plate, and two sets of push plates fixedly connected to the U-shaped frame are fixedly connected to the connecting plate. The top two sides of the material feeding frame are fixedly connected to limiting plates that are locked and slidably connected to the push plates.

[0012] Preferably, a lifting plate is vertically slidably connected to the U-shaped frame, and the lifting plate is slidably connected to two sets of auxiliary clamps. An electric push rod is fixedly installed on the U-shaped frame, and the output end of the electric push rod is fixedly connected to the lifting plate.

[0013] Preferably, the bottom of the lifting plate is rotatably connected to a gear via a rotating shaft, and both sets of auxiliary clamps are fixedly connected to toothed plates that mesh with the gears, with the two sets of toothed plates being staggered. An electric push rod is installed between one set of auxiliary clamps and the lifting plate.

[0014] Preferably, a feeding column is fixedly connected to one side of the lifting plate via an L-shaped plate, and a square tube is slidably connected to one end of the feeding column. An arc-shaped plate is fixedly connected to the square tube, and a rubber pad is fixedly connected to the concave side of the arc-shaped plate. A cavity is opened inside the rubber pad. A negative pressure pipe is fixedly installed on the square tube, and a connecting spring is fixedly installed between the arc-shaped plate and the feeding column.

[0015] The beneficial effects of this invention are as follows:

[0016] (1) The present invention provides internal support by setting reinforcing columns inside the cavity of the photovoltaic aluminum alloy frame, which forms a reliable top support for the punching area of ​​the profile during the side punching process. This effectively avoids irregular plastic deformation such as dents and twists caused by punching pressure in the cavity of the frame. At the same time, when the photovoltaic module is installed and fastened with countersunk bolts, the support of the reinforcing columns on the inner wall of the frame can prevent the bolt tightening force from causing the side wall of the frame to dent or the whole to deform. This significantly improves the structural strength and stability of the frame connection part and ensures the regularity of the shape and the structural reliability of the photovoltaic aluminum alloy frame throughout the processing and assembly process.

[0017] (2) The present invention also uses negative pressure adsorption in conjunction with an arc plate with a cavity rubber pad to grasp and fix the reinforcing column, which can be adapted to reinforcing columns of different diameters, taking into account both versatility and sealing stability. At the same time, the elastic sliding connection structure between the arc plate and the feeding column, combined with the limiting cone surface at the end of the reinforcing column and the punch guide, automatically corrects the axis offset caused by size difference or the sagging of the feeding column during the punching process, realizes the coaxial adaptive adjustment of the reinforcing column and the punch, ensures accurate punching position and regular hole shape, and greatly improves the equipment's adaptability to photovoltaic frames and reinforcing columns of different specifications and the punching processing accuracy.

[0030] 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.

[0031] Example 1: Please refer to Figures 1-7 As shown, for the hollow cavity structure of the frame without a matching internal support structure, when punching the cavity area of ​​the frame, the lateral punching pressure cannot be effectively balanced and reversed, resulting in a high concentration of local stress in the thin-walled area around the hole. This easily causes plastic deformation problems such as concave collapse, edge warping, out-of-round hole shape, and burrs on the cross-section of the profile sidewall. The following solutions can be used to solve these problems.

[0032] The horizontal side punching equipment for processing photovoltaic aluminum alloy frames in this embodiment includes a feeding frame 1, a limiting baffle 11 fixedly connected to the top side of the feeding frame 1, a U-shaped frame 2 movably installed on the top of the feeding frame 1, and two sets of auxiliary clamping plates 21 provided on the U-shaped frame 2. A punch 23 for punching photovoltaic aluminum alloy frames is detachably installed on the auxiliary clamping plates 21. The punch 23 is connected to the auxiliary clamping plates 21 by bolts so that different sizes of punch 23 can be replaced to achieve punching processing of different diameters.

[0033] Furthermore, reinforcing columns 3 are provided between the punches 23 to float in position and assist the punches 23 in avoiding irregular deformation of the punching area of ​​the photovoltaic aluminum alloy frame. Based on the thickness of the inner cavity of the photovoltaic aluminum alloy frame, reinforcing columns 3 of corresponding length and diameter are selected. The reinforcing columns 3 serve as internal support for the inner cavity of the frame, forming a reliable top support for the punching area of ​​the profile during the side punching process, effectively preventing irregular plastic deformation such as dents and twists in the cavity of the frame caused by the punching pressure.

[0034] Meanwhile, when countersunk bolts are used for fastening during the subsequent installation of photovoltaic modules, the support of the reinforcing column 3 on the inner wall of the frame can prevent the bolt tightening force from causing the side wall of the frame to dent or the whole to deform, which significantly improves the structural strength and stability of the frame connection part and ensures the regularity of the shape and the structural reliability of the photovoltaic aluminum alloy frame throughout the entire process of processing and assembly.

[0035] The punch 23 has a stepped shaft structure, and the free end of the punch 23 and the stepped surface are respectively provided with a punching conical surface 24 and a stamping conical surface 25. Multiple punching and cutting blades 26 are fixedly connected at equal intervals on the punching conical surface 24. The two sets of auxiliary clamping plates 21 move synchronously relative to each other, so that the ends of the two sets of punches 23 simultaneously abut against the outer walls on both sides of the photovoltaic aluminum alloy frame. First, the reinforcing column 3 limits the contact of the inner cavity of the photovoltaic aluminum alloy frame to avoid irregular extrusion deformation around the hole during punching and extrusion.

[0036] Then, with the help of multiple punching and cutting blades 26 at the end of the punch 23, the punching points on the side wall of the photovoltaic aluminum alloy frame are cut into segments to reduce the punching extrusion pressure. Then, the segmented waste material is squeezed into the interior of the reinforcing column 3 through the punching conical surface 24 on the punch 23, thus initially completing the fixation of the reinforcing column 3 in the inner cavity of the photovoltaic aluminum alloy frame. The punching and cutting blades 26 on the two sets of punches 23 are staggered to ensure that the waste material is staggered and distributed into the interior of the reinforcing column 3 when punching holes on both sides of the frame cavity, avoiding overlapping contact, which would make it difficult to insert bolts during subsequent frame installation.

[0037] The reinforcing column 3 has through holes extending through both ends of its interior. The edges of the through holes are fitted with limiting cone surfaces 31 that are compatible with the stamped conical surface 25. By combining the stamped conical surface 25 on the punch 23 with the limiting cone surfaces 31 on the end faces of the reinforcing column 3, controllable and regular conical deformation extrusion is achieved around the hole, which strengthens and fixes the reinforcing column 3 in a secondary manner. Countersunk holes are formed on the surface of the photovoltaic aluminum alloy frame so that the photovoltaic aluminum alloy frame can be fixed with countersunk bolts during installation. This effectively avoids the problem of secondary deformation of the photovoltaic aluminum alloy frame during bolt tightening, thereby improving the connection strength.

[0038] The material feeding frame 1 has an I-shaped limiting slide groove inside, and a limiting slide column 12 that is adapted to it and drives the U-shaped frame 2 to move is slidably connected in the limiting slide groove. A lead screw 13 that is threadedly connected to the limiting slide column 12 is rotatably connected in the limiting slide groove. A servo motor 14 that drives the lead screw 13 to rotate is installed on the material feeding frame 1 by bolts.

[0039] The free end of the limiting slide column 12 is fixedly connected to a connecting plate 15, and two sets of push plates 16 fixedly connected to the U-shaped frame 2 are fixedly connected to the connecting plate 15. The top two sides of the material feeding frame 1 are fixedly connected to limiting plates that are locked and slidably connected to the push plates 16.

[0040] The locking sliding connection between the push plate 16 and the limiting plate is used to stabilize the spacing of the vertical sections on both sides of the U-shaped frame 2, thereby effectively extending the service life of the U-shaped frame 2. With the limiting baffle 11 located on one side of the U-shaped frame 2 as a reference plane, one end of the photovoltaic aluminum alloy frame abuts against the limiting baffle 11. The servo motor 14 drives the lead screw 13 to rotate, and the lead screw 13 pushes the limiting slide column 12 to carry the U-shaped frame 2 to move horizontally, so as to realize the processing of punching points at different positions at the same height.

[0041] A lifting plate 27 is vertically slidably connected to the U-shaped frame 2, and the lifting plate 27 is slidably connected to two sets of auxiliary clamping plates 21. An electric push rod 28 is fixedly installed on the U-shaped frame 2, and the output end of the electric push rod 28 is fixedly connected to the lifting plate 27. The top of the material placement frame 1 is a reference plane. The photovoltaic aluminum alloy frame is placed on the top of the material placement frame 1. The electric push rod 28 pushes the lifting plate 27 to rise or fall, so that the punch 23 moves to different height punching points for processing.

[0042] The bottom of the lifting plate 27 is rotatably connected to a gear 29 via a rotating shaft. Both sets of auxiliary clamping plates 21 are fixedly connected to toothed plates 210 that mesh with the gear 29, and the two sets of toothed plates 210 are staggered. One set of auxiliary clamping plates 21 and the lifting plate 27 are connected to an electric push rod 211. The electric push rod 211, in conjunction with the toothed plate 210 and the gear 29, synchronously drives the two sets of auxiliary clamping plates 21 to move relative to or away from each other, and synchronously completes the punching process on both sides of the frame cavity.

[0043] Example 2: Please refer to Figures 4-6 As shown, the following solutions can be used to address the problems of the reinforcing columns extending rapidly into the inner cavity of the photovoltaic aluminum alloy frame, and the difficulty in accurately aligning the punching holes due to axial offset when fixing different reinforcing columns.

[0044] In this embodiment, two sets of combined limiting baffles 11 are fixedly installed on opposite sides of the auxiliary clamping plate 21. The spring clip 22, which is centered on the photovoltaic aluminum alloy frame, is positioned so that the distance between the free ends of the spring clip 22 on the auxiliary clamping plate 21 is less than the thickness of the photovoltaic aluminum alloy frame. The photovoltaic aluminum alloy frame is placed on the material placement frame 1 and passes through the spring clips 22 on both sides and abuts against the limiting baffles 11, thus quickly completing the positioning and placement of the photovoltaic aluminum alloy frame. The auxiliary reinforcing column 3 extends into the interior of the photovoltaic aluminum alloy frame at the same time.

[0045] The spring clips 22 are tilted. When the two sets of auxiliary clamping plates 21 move relative to each other to perform punching, the tilted setting of the two sets of spring clips 22 helps to push the photovoltaic aluminum alloy frame to further contact the limiting baffle 11 when bending deformation occurs, which further improves the precise alignment of the hole and the punch 23. In addition, the free end of the spring clips 22 is fixedly connected with a rubber block to avoid the spring clips 22 from scratching the outer wall of the photovoltaic aluminum alloy frame.

[0046] A feeding column 33 is fixedly connected to one side of the lifting plate 27 via an L-shaped plate 32, and a square tube 34 is slidably connected to one end of the feeding column 33. An arc plate 35 is fixedly connected to the square tube 34, and a rubber pad 36 is fixedly connected to the concave side of the arc plate 35. The rubber pad 36 has a cavity inside. A negative pressure pipe 37 is fixedly installed on the square tube 34. An external negative pressure adsorption device is connected to the negative pressure pipe 37. The reinforcing column 3 is placed on the concave side of the arc plate 35. The selected reinforcing column 3 is adsorbed and fixed by the negative pressure adsorption device in combination with the negative pressure pipe 37 and the square tube 34. When the reinforcing column 3 of different diameters is adsorbed and fixed, the rubber pad 36 with a cavity inside deforms to maintain the connection and sealing between the reinforcing column 3 and the arc plate 35.

[0047] A connecting spring 38 is fixedly installed between the arc plate 35 and the feeding column 33. The connecting spring 38 is used to realize the elastic sliding connection between the arc plate 35 and the feeding column 33. When the reinforcing columns 3 of different diameters are adsorbed and fixed, the arc of the arc plate 35 is fixed, so the axis of the reinforcing columns 3 of different diameters is located on one side of the axis of the punch 23 after they are fixed.

[0048] Furthermore, due to the excessive distance between the connection point of the free end of the feeding column 33 and the L-shaped plate 32, the feeding column 33, combined with the weight of the arc plate 35 and the reinforcing column 3, causes a slight downward deformation at the end of the feeding column 33. This results in the centerline of the reinforcing column 3 being located on one side below the centerline of the punch 23. Through the elastic sliding connection between the arc plate 35 and the feeding column 33, combined with the limiting cone surface 31 on the end face of the reinforcing column 3, the punching and cutting blade 26 can perform a floating self-adjustment of the centerline after entering the limiting cone surface 31, so that the reinforcing column 3 is accurately positioned at the punching position.

[0049] Example 3: Please refer to Figures 1-7 As shown, the present invention also proposes a method for using a horizontal side-punching device applied to the processing of photovoltaic aluminum alloy frames, including the following steps:

[0050] Step 1: First, based on the thickness of the inner cavity of the photovoltaic aluminum alloy frame, select a reinforcing column 3 of corresponding length and diameter, and place it on the concave side of the arc plate 35. The external negative pressure adsorption device is connected to the negative pressure pipe 37. The selected reinforcing column 3 is adsorbed and fixed by the negative pressure adsorption device in combination with the negative pressure pipe 37 and the square pipe 34. In addition, when adsorbing and fixing reinforcing columns 3 of different diameters, the rubber pad 36 with an internal cavity is deformed to maintain the connection and sealing between the reinforcing column 3 and the arc plate 35.

[0051] Step 2: Using the limiting baffle 11 located on one side of the U-shaped frame 2 and the top of the material placement frame 1 as two reference planes, the servo motor 14 drives the lead screw 13 to rotate. The lead screw 13 pushes the limiting slide column 12 to carry the U-shaped frame 2 to move horizontally, and the electric push rod 28 pushes the lifting plate 27 to rise or fall, so that the punch 23 and the reinforcing column 3 move synchronously to the punching point. Then, according to the thickness of the photovoltaic aluminum alloy frame, the electric push rod 211, combined with the toothed plate 210 and the gear 29, adjusts the distance between the two sets of auxiliary clamping plates 21 so that the distance between the free ends of the spring clips 22 on the auxiliary clamping plates 21 is less than the thickness of the photovoltaic aluminum alloy frame. The photovoltaic aluminum alloy frame is placed on the material placement frame 1 and passes through the spring clips 22 on both sides and abuts against the limiting baffle 11, quickly completing the positioning and placement of the photovoltaic aluminum alloy frame. The auxiliary reinforcing column 3 extends synchronously and quickly into the interior of the photovoltaic aluminum alloy frame.

[0052] Step 3: The electric push rod 211 pushes the two sets of auxiliary clamps 21 to move synchronously relative to each other, causing the ends of the two sets of punches 23 to simultaneously abut against the outer walls of both sides of the photovoltaic aluminum alloy frame. First, the reinforcing column 3 limits the contact of the inner cavity of the photovoltaic aluminum alloy frame to avoid irregular extrusion deformation around the hole during punching. Then, the multiple punching and cutting blades 26 at the end of the punch 23 are used to cut the punching points on the side wall of the photovoltaic aluminum alloy frame into segments to reduce the punching extrusion force. Finally, the segmented waste material is squeezed through the punching conical surface 24 on the punch 23. The reinforcing column 3 is initially fixed in the inner cavity of the photovoltaic aluminum alloy frame by the through hole of the reinforcing column 3. Then, the punching conical surface 25 on the punch 23 is combined with the limiting conical surface 31 on the end face of the reinforcing column 3 to perform controllable regular conical deformation extrusion around the hole, thereby strengthening and fixing the reinforcing column 3 for the second time. This forms a countersunk hole on the surface of the photovoltaic aluminum alloy frame so that the photovoltaic aluminum alloy frame can be fixed with countersunk bolts during installation. The reinforcing column 3 also effectively prevents the photovoltaic aluminum alloy frame from deforming during bolt tightening, thereby improving the connection strength.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
