Technical Field

[0001] This utility model relates to the field of aluminum alloy frame processing technology, specifically to a positioning and cutting device for processing aluminum alloy frames for photovoltaic panels. Background Technology

[0002] In the current booming development of the photovoltaic industry, photovoltaic panels, as core components, are crucial in every step of their production and manufacturing process. The aluminum alloy frame of the photovoltaic panel, as a key structure protecting the panel, not only needs to possess good mechanical strength and corrosion resistance, but also has extremely high requirements for dimensional accuracy and processing quality.

[0003] The aluminum alloy frames for photovoltaic panels vary in size, and existing processing, positioning, and cutting devices are difficult to adapt to different frame sizes. When processing frames of different sizes, it is necessary to manually change the positioning fixtures, which seriously disrupts the production rhythm and makes continuous operation difficult. Therefore, there is a need for a processing, positioning, and cutting device for aluminum alloy frames of photovoltaic panels. Utility Model Content

[0004] The purpose of this utility model is to provide a processing, positioning, and cutting device for aluminum alloy frames of photovoltaic panels. By setting adjustable positioning components, it can be adapted to frames of different sizes, thereby solving the technical problems mentioned in the background art.

One set of support platforms can slide on the upper part of the base. Two sets of L-shaped clamping blocks are slidably mounted on the upper part of each set of support platforms.

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

[0022] This utility model provides: a positioning and cutting device for processing aluminum alloy frames for photovoltaic panels, such as... Figures 1-4 As shown, the device includes a worktable 1, on the upper part of which is a positioning component 2 that can be adjusted according to the frame size. The worktable 1 is the basic load-bearing component of the entire device, providing an installation surface and working space for the positioning component 2 and other components. The positioning component 2 can be adjusted according to the size of the aluminum alloy frame, thereby enabling it to be used with frames of different sizes and increasing the practicality of the device.

[0023] The positioning component 2 includes a base 201 mounted on the upper part of the worktable 1. Two sets of support platforms 202 are mounted on the upper part of the base 201. One set of support platforms 202 can slide on the upper part of the base 201. Two sets of opposing L-shaped clamping blocks 205 are slidably mounted on the upper part of each set of opposing clamping blocks 205. A bidirectional screw 206 is rotatably mounted through the middle of each pair of opposing clamping blocks 205. A servo motor 207 and a fixing bracket 208 are respectively connected to the two ends of the bidirectional screw 206. The base 201 is fixed to the upper part of the worktable 1. Of the two sets of support platforms 202 mounted on it, one set is slidable and the other is fixed. By adjusting the position of the sliding support platform 202 on the base 201, the distance between the two sets of support platforms 202 can be changed, thereby adapting to aluminum alloy frame profiles of different lengths. The two sets of opposing L-shaped clamping blocks 205 on each set of support platforms 202 slide synchronously through the bidirectional screw 206 in the middle. When the servo motor 207 drives the bidirectional screw 206 to rotate, the reverse threads at both ends of the screw cause the clamping blocks 205 on both sides to move in opposite directions, thereby adjusting the clamping width and ensuring that frames of different widths can be stably fixed. The fixing frame 208 is used to support the other end of the bidirectional screw 206 to ensure the stability of the screw during rotation. This structure, through the sliding adjustment of the support platform 202 and the synchronous movement of the L-shaped clamping blocks 205, achieves dimensional adaptation in the length and width directions of the frame, eliminating the need for manual clamp replacement and significantly improving positioning efficiency.

[0024] The servo motor 207 can be configured with a rated power of 100-200W, a speed of 1000-3000rpm, and a positioning accuracy of ±0.01mm. The 00-200W power provides sufficient torque to drive the screw rotation, overcoming the sliding friction of the clamping block 205 (single load ≤5kg); the 1000-3000rpm speed, combined with the screw lead, allows the clamping block 205 to move at a speed of 50-150mm / s, meeting the needs for rapid clamping of frames of different widths; the ±0.01mm positioning accuracy is controlled by encoder feedback, ensuring that the synchronization error of the clamping blocks 205 on both sides is <0.05mm, avoiding frame deformation caused by clamping misalignment.

[0025] Preferably, a stepper motor 203 is mounted on the side wall of the base 201 to drive the lead screw 204 to rotate, and a slidable support platform 202 is threaded onto the middle of the lead screw 204. The stepper motor 203 drives the rotation of the lead screw 204, enabling precise adjustment of the position of the slidable support platform 202. The lead screw 204 passes through the slidable support platform 202 and is threadedly connected to it. When the stepper motor 203 drives the lead screw 204 to rotate, the threaded transmission converts the rotational motion into linear sliding motion of the support platform 202. This not only improves the automation of spacing adjustment but also allows for rapid positioning by pre-setting the position of the support platform 202 corresponding to different frame lengths through the control system, avoiding human error and further improving production efficiency and positioning accuracy.

[0026] The stepper motor 203 can be configured with a step angle of 1.8°, a rated torque of 0.5-1 N·m, and a speed of 100-300 rpm. The 1.8° step angle can achieve sub-micron level positioning accuracy through a microstepping driver, adapting to precise adjustments for frames of different lengths; the 0.5-1 N·m torque can drive the sliding load of the support platform 202, avoiding step loss due to insufficient torque; the 100-300 rpm speed balances adjustment efficiency and control stability, and this range can complete the spacing adjustment within a 1-meter length range within 5 seconds, meeting the needs of continuous production.

[0027] Furthermore, each set of clamping blocks 205 has a threaded hole 209 in the middle that matches the external thread of the bidirectional screw 206. Two sets of opposing clamping blocks 205 are installed at both ends of the corresponding bidirectional screw 206 through the threaded hole 209. A buffer pad 210 is attached to the clamping surface of each set of clamping blocks 205. The threaded hole 209, through its engagement with the external thread of the bidirectional screw 206, allows the clamping blocks 205 to slide along the support platform 202 when the bidirectional screw 206 rotates. When the servo motor 207 drives the bidirectional screw 206 to rotate, the clamping blocks 205 on both sides will move closer or further apart synchronously due to the reverse threads at both ends of the screw, achieving precise adjustment of the clamping width. The buffer pad 210, made of elastic material, adheres to the clamping surface of the clamping blocks 205 and effectively buffers the clamping force when clamping the frame, preventing indentations or deformation on the aluminum alloy frame surface due to rigid clamping. This ensures clamping stability and protects the surface quality of the frame profile.

[0028] Furthermore, each set of clamping blocks 205 has a rotatable connecting block 211 mounted on its upper part, a screw 212 rotatably mounted on the middle of each set of connecting blocks 211, and a rubber block 213 abutting against the upper surface of the frame at the bottom of each set of screws 212. The connecting block 211 is rotatably mounted on the upper part of the clamping block 205, allowing the screw 212 to adjust its angle in the horizontal plane, avoiding any impact on the frame installation. The screw 212 passes through the connecting block 211 via a threaded connection, and rotating the screw 212 can adjust its vertical position, allowing the bottom rubber block 213 to tightly abut against the upper surface of the frame. The elastic contact of the rubber block 213 not only increases the vertical fixing force of the frame, preventing displacement caused by vibration during processing, but also avoids scratches caused by direct contact between the metal screw and the frame surface.

[0029] It is worth noting that two sets of support frames 3 are symmetrically installed on the upper surface of the worktable 1, and a sliding module 4 is installed in the middle of the two sets of support frames 3. The support frames 3 are symmetrically fixed to the upper surface of the worktable 1, providing support for the sliding module 4 and its output end components. The sliding module 4 is installed in the middle of the two sets of support frames 3, and typically includes a linear guide rail and a slider, which can drive the connecting components to reciprocate in the horizontal direction, thereby driving the cutting assembly 7 to move along the length of the frame, realizing cutting operations at different positions.

[0030] The sliding module 4 is a linear guide rail type with a repeatability of ±0.05mm and a load capacity of 50-100kg. The ±0.05mm repeatability ensures consistent cutting position and avoids cut deviation caused by module error; the 50-100kg load capacity can accommodate the electric push rod 5, the fixing plate 6 and the cutting assembly 7, and withstand the lateral force during cutting to prevent guide rail deformation from affecting cutting accuracy.

[0031] Specifically, an electric push rod 5 is installed at the output end of the sliding module 4. The electric push rod 5 is used to drive the cutting assembly 7 to move vertically. The electric push rod 5 drives the cutting assembly 7 to move up and down in the vertical direction, realizing the feed and retraction of the cutting tool. When the sliding module 4 moves the electric push rod 5 to the target cutting position, the electric push rod 5 controls the vertical height of the cutting assembly 7 through the extension and retraction of the telescopic rod, so that the tool contacts or leaves the frame profile, thereby adjusting the cutting depth.

[0032] The electric linear actuator has five parameters: thrust of 100-200N, speed of 5-20mm / s, and positioning accuracy of ±0.1mm. The 100-200N thrust overcomes the axial resistance of the cutting tool, preventing feed jamming due to insufficient thrust; the 5-20mm / s speed adapts to different cutting processes and, in conjunction with a servo system, achieves uniform feed; the ±0.1mm positioning accuracy ensures a cutting depth error of <0.2mm, meeting the height tolerance requirements of photovoltaic frame cuts and preventing frame scrap due to overcutting or undercutting.

[0033] More specifically, the output end of the electric push rod 5 is connected to the fixing plate 6, and the cutting assembly 7 is installed in the middle of the fixing plate 6. The fixing plate 6 is used to connect the electric push rod 5 and the cutting assembly 7. The cutting assembly 7 is rigidly connected to the fixing plate 6, which transmits the vertical driving force of the electric push rod 5 and the horizontal driving force of the sliding module 4 to the cutting assembly 7, so that they move in coordination in two directions. This enhances the installation rigidity of the cutting assembly 7, reduces vibration and offset during the movement, and, together with the stable clamping of the frame by the positioning assembly 2, enables high-precision cutting operations, ensuring the flatness and dimensional accuracy of the frame cut.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
