Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of photovoltaic module manufacturing equipment, specifically relating to a photovoltaic panel frame stamping, positioning and pressing device. Background Technology
[0002] As a key structural component of photovoltaic modules, the stamping precision of the photovoltaic frame directly affects the assembly quality and structural strength of the photovoltaic panel. After the frame and corner keys are installed, protrusions need to be formed by stamping to enhance the connection strength; therefore, the positioning accuracy during the stamping process is crucial.
[0003] In the prior art, utility model patent CN217665683U discloses a frame stamping and positioning mechanism for a photovoltaic module frame. This mechanism achieves frame positioning through a fixed stop, a movable stop, a lead screw, and a handwheel. Specifically, the handwheel rotates the screw sleeve, causing the lead screw to rotate, which moves the movable stop to the left and together with the fixed stop clamps the frame body. However, this technical solution has the following drawbacks:
[0004] Firstly, the unidirectional positioning is achieved only through the end stops, which lacks effective constraints on the top and sides of the frame. During stamping, it is easy to cause vertical movement and lateral displacement, resulting in deformation or dimensional deviation of the stamped part.
[0005] Secondly, using manual adjustment of the handwheel for positioning is not only inefficient, but also its positioning accuracy is greatly affected by manual operation.
[0006] Third, the movable stop makes hard contact with the frame without a buffer protection structure, which can easily damage the oxide film on the frame surface.
[0007] Fourth, the positioning mechanism has a single adjustment dimension, which cannot adapt to the diverse processing needs of different frame sizes, resulting in poor versatility.
[0008] To address the problems of insufficient positioning accuracy, low operating efficiency, and poor versatility in existing technologies, this utility model proposes a multi-directional, collaborative, and precisely adjustable photovoltaic panel frame stamping, positioning, and clamping device. Summary of the Invention
[0009] This utility model aims to solve one of the technical problems existing in the prior art.
[0010] This application provides a stamping, positioning, and clamping device for a photovoltaic panel frame, including a stamping machine body, a moving die, a fixed die, and a clamping device. The clamping device includes a top clamping component, a side clamping component, and an end clamping component, which are used to clamp the top surface, side surface, and end of the photovoltaic panel frame, respectively, and to clamp the photovoltaic panel frame onto the fixed die.
[0011] The top surface clamping component includes a connecting rod and several top surface clamping plates. The top surface clamping plates are fixed on the connecting rod, and the rotation of the connecting rod drives the top surface clamping plates to press against or move away from the photovoltaic panel frame.
[0012] A fixing hole is made on the top pressure plate, and the plate is fixedly sleeved onto the connecting rod through the fixing hole.
[0013] A buffer block is fixed to the top pressure plate away from the connecting rod end.
[0014] The side clamping component includes a side clamping plate and a near post. One end of the side clamping component is fixedly connected to the connecting rod, and the bottom of the other end is fixedly attached to the near post.
[0015] The side clamping component includes a side clamping plate body, an upper snap flap, a lower snap flap, a fastener, and a fastener. The upper snap flap is fixedly connected to the side clamping plate body. The fastener and fastener are used to make the upper snap flap and the lower snap flap detachably connected to each other. An installation groove for mating with a connecting rod is formed between the upper snap flap and the lower snap flap.
[0016] The fastening element includes a pair of L-shaped connecting blocks, each L-shaped connecting block being fixed on the upper and lower snap flaps respectively and engaging with each other.
[0017] The side clamping component also includes a horizontal adjustment groove and a vertical adjustment stud. The horizontal adjustment groove is located at the end of the side clamping plate away from the connecting rod and extends along the length of the side clamping plate. The vertical adjustment stud passes through the horizontal adjustment groove and is fixed by multiple nuts. The stud can be detachably installed at the bottom of the vertical adjustment stud through a threaded hole near the stud.
[0018] The vertical adjustment stud has a nut at the top, middle and bottom. The two nuts at the top are used to fix the vertical adjustment stud to the side pressure plate body, and the nut at the bottom is used to reinforce the threaded connection between the vertical adjustment bolt and the stud.
[0019] The beneficial effects of this utility model are as follows:
[0020] 1. Three-dimensional collaborative positioning: Through the collaborative action of the top, side and end clamping parts, a three-dimensional positioning system is formed, which restricts the displacement of the frame from three dimensions, solving the problem of movement caused by the unidirectional positioning of the existing technology, and improving the positioning accuracy by more than 30%.
[0021] 2. Adaptive adjustment capability: The combination structure of the horizontal adjustment slot and the vertical adjustment stud can realize stepless adjustment in the horizontal and vertical directions near the stud, adapting to various frame sizes and significantly improving versatility.
[0022] 3. Optimized protection performance: The buffer block at the end of the top pressure plate is made of rubber, which absorbs the impact force through elastic deformation, avoids damage to the oxide film on the frame surface, and reduces the scrap rate.
[0023] 4. Improved operational efficiency: The use of a pusher cylinder replaces manual adjustment, shortening the end-positioning response time.
[0024] With the linkage structure, the overall machining cycle time is improved.
[0025] 5. Enhanced structural stability: The L-shaped connecting block interlocking structure of the upper and lower snap flaps, combined with multiple nut locking, ensures the stability of positioning accuracy during long-term use, and extends the maintenance cycle to more than 3 months.

Detailed Implementation
[0033] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0034] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0035] The photovoltaic panel frame stamping, positioning, and pressing device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0036] Example 1:
[0037] This application provides a photovoltaic panel frame stamping, positioning, and clamping device, including a stamping machine body 1, a moving mold 2, a fixed mold 3, and a clamping device 4. The clamping device 4 includes a top surface clamping member 41, a side surface clamping member 42, and an end clamping member 426, which are used to clamp the top surface, side surface, and end of the photovoltaic panel frame, respectively, and clamp the photovoltaic panel frame onto the fixed mold 3.
[0038] like Figures 1 to 3 As shown, due to the aforementioned structure, when the photovoltaic panel frame blank is conveyed between the fixed mold 3 and the moving mold 2, the top clamping member 41 first applies vertical pressure from the top surface of the frame, pressing the frame firmly against the top reference surface of the fixed mold 3, preventing the frame from moving up and down during the stamping process; the side clamping member 42 exerts force from the side of the frame, pushing the frame closer to the side reference of the fixed mold 3, eliminating the gap between the frame and the side of the fixed mold 3, and limiting its horizontal displacement; the end clamping member 426 abuts against the end of the frame, ensuring the positioning accuracy of the frame in the length direction, and preventing the frame length dimension from being unqualified after stamping due to end position deviation. The three components work together to form a three-dimensional clamping and positioning effect, ensuring that the frame always maintains a precise fit with the fixed mold 3 during the stamping process, effectively solving the problems of deformation, dimensional deviation, and burrs on the stamping edge caused by inaccurate positioning in the prior art, while reducing the relative sliding between the frame and the mold, and reducing the risk of surface scratches.
[0039] Example 2:
[0040] The difference from Embodiment 1 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the top surface clamping member 41 includes a connecting rod 411 and a plurality of top surface clamping plates 412. The top surface clamping plates 412 are fixed on the connecting rod 411, and the top surface clamping plates 412 are pressed or moved away from the photovoltaic panel frame by rotating the connecting rod 411.
[0041] In this embodiment of the application, a fixing hole is provided on the top surface pressing plate 412, and the plate is fixedly sleeved on the connecting rod 411 through the fixing hole.
[0042] In this embodiment of the application, a buffer block 413 is fixedly provided at the end of the top surface pressing plate 412 away from the connecting rod 411.
[0043] like Figures 1 to 3 As shown, due to the aforementioned structure, when the connecting rod 411 rotates under the drive mechanism, it can simultaneously drive several top-surface pressing plates 412 fixed on the connecting rod 411 (with a hexagonal cross-section) to rotate, thereby synchronously pressing or releasing the top surface of the photovoltaic panel frame. This ensures uniform force distribution at each pressing point on the top surface of the frame, avoiding frame deformation caused by localized overpressure. The top-surface pressing plates 412 are connected to the connecting rod via fixing holes.
[0044] The 411 fixed connection ensures consistent movement between the two and prevents the clamping plate from loosening and affecting positioning accuracy. The buffer block 413 (made of rubber or silicone) at the end away from the connecting rod 411 can absorb the impact force of the clamping moment through elastic deformation when it contacts the top surface of the frame, avoiding damage to the oxide film and coating on the surface of the frame (preventing scratches from damaging corrosion resistance and insulation). It can also enhance the fit with the frame through its own friction, further improving the clamping stability and reducing the small displacement caused by stamping vibration.
[0045] Example 3:
[0046] The difference from Embodiment 2 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the side clamping member 42 includes a side clamping plate 421 and a near post 422. One end of the side clamping plate 421 is fixedly connected to the connecting rod 411, and the bottom of the other end is fixedly attached to the near post 422.
[0047] In this embodiment of the application, the side clamping plate 421 includes a side clamping plate body 4211, an upper snap flap 4212, a lower snap flap 4213, a fastener, and a fastener. The upper snap flap 4212 is fixedly connected to the side clamping plate body 4211. The fastener and fastener are used to make the upper snap flap 4212 and the lower snap flap 4213 detachably connected to each other. An installation groove for cooperating with the connecting rod 411 is formed between the upper snap flap 4212 and the lower snap flap 4213.
[0048] In this embodiment of the application, the fastening component includes a pair of L-shaped connecting blocks 4214, each L-shaped connecting block 4214 being fixedly mounted on the upper fastening flap 4212 and the lower fastening flap 4213 respectively and engaging with each other.
[0049] like Figures 1 to 3 As shown, due to the above structure, the side clamping plate 421 is secured by the upper latch.
[0050] 4212. The lower snap flap 4213 and the connecting rod 411 form a stable connection. The upper snap flap 4212 is fixed to the side pressure plate body 4211. The lower snap flap 4213 is engaged with the upper snap flap 4212 through the L-shaped connecting block 4214. With the help of fasteners (such as bolts and nuts), the two can be tightly fixed, which not only ensures the synchronous movement of the side pressure plate 421 and the connecting rod 411, but also facilitates disassembly and maintenance in the later stage. When the connecting rod 411 drives the side pressure plate 421 to move, the column 422 can accurately abut against the side of the frame, forming a synergistic effect of "top surface fixing + side pushing" with the top surface pressure member 41: the top surface pressure member 41 restricts the vertical displacement of the frame, while the column 422 continuously applies pushing force from the side to ensure that the frame always fits the side reference of the fixed mold 3, avoiding the side displacement of the frame due to the impact force of the moving mold 2 during stamping, thereby reducing the deformation and dimensional deviation of the punching part caused by displacement, and reducing the risk of surface scratches caused by friction between the frame and the mold.
[0051] Example 4:
[0052] The difference from Embodiment 3 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the side clamping member 42 also includes a horizontal adjustment groove 423 and a vertical adjustment stud, which allows for horizontal adjustment.
[0053] The groove 423 is opened at the end of the side clamping plate 421 away from the connecting rod 411 and extends along the length of the side clamping plate 421. The vertical adjusting stud is inserted in the horizontal adjusting groove 423 and fixed by multiple nuts 425. It is detachably installed at the bottom of the vertical adjusting stud near the column 422 through a threaded hole.
[0054] In this embodiment of the application, a nut 425 is provided at the top, middle and bottom of the vertical adjustment stud. The two nuts 425 at the top are used to fix the vertical adjustment stud to the side pressure plate body 4211, and the nut 425 at the bottom is used to reinforce the threaded connection between the vertical adjustment bolt 424 and the stud 422.
[0055] like Figures 3 to 5As shown, due to the aforementioned structure, the horizontal adjustment groove 423 provides the vertical adjustment stud with a moving space along the length of the side clamping plate 421. By adjusting the position of the vertical adjustment stud within the horizontal adjustment groove 423, the contact point between the stud near the column 422 and the side of the frame can be precisely changed to accommodate photovoltaic panel frames of different widths. The vertical adjustment stud is fixed in the horizontal adjustment groove 423 by nuts 425 at the top and middle, which not only locks its horizontal position but also allows adjustment of its vertical height near the column 422 by rotating the stud, ensuring that the contact point between the stud near the column 422 and the frame is accurate. The contact height on the side matches the reference surface of the frame side to avoid lateral force deviation caused by height deviation. The bottom nut 425 further reinforces the connection between the near post 422 and the vertical adjusting stud to prevent the near post 422 from loosening due to stamping vibration. This adjustable structure allows the side clamping part 42 to flexibly adapt to various frame specifications. Through precise adjustment, it ensures that the direction and magnitude of the thrust of the near post 422 on the side of the frame are controllable, effectively improving the positioning accuracy and reducing problems such as punching burrs and dimensional deviations caused by positioning deviation. At the same time, it enhances the versatility of the device.
[0056] Example 5:
[0057] The difference from Embodiment 4 is that, in this embodiment, in addition to including the structural features of the aforementioned embodiments, the end clamping member 426 includes an abutment plate 431 and a pusher cylinder 432, which are respectively fixed at both ends of the fixed mold 3.
[0058] like Figure 2 As shown, due to the aforementioned structure, when the photovoltaic panel frame blank is conveyed to the fixed mold 3, the push cylinders 432 at both ends of the fixed mold 3 are activated, driving the abutment plate 431 to apply a pushing force synchronously from both ends of the frame towards the middle, so that both ends of the frame are tightly abutted against the abutment plate 431 respectively. During this process, the pushing force of the push cylinder 432 is controllable and stable, ensuring that the frame is accurately positioned in the length direction and ensuring the accuracy of the punching position in the length direction of the frame. At the same time, the end abutment, the top surface clamping member 41, and the side surface clamping member 42 form a three-dimensional collaborative positioning of "top surface fixing, side surface pushing, and end limit": the top surface and side surface clamping member 42...
[0059] The fastener 42 restricts the vertical and horizontal lateral displacement of the frame, while the end abutment plate 431 locks the frame position in the length direction to prevent the frame from moving along the length direction due to the impact force of the moving die 2 during the stamping process. This reduces the relative sliding between the frame and the die, protects the surface oxide film and coating, and ensures the weather resistance of the frame. In addition, the driving method of the pusher cylinder 432 can be adapted to frames of different lengths, improving the versatility of the device.
