Description

Technical Field

[0001] This application relates to the technical field of aluminum frame production for photovoltaic panels, and in particular to an aluminum frame feeding assembly and an aluminum frame feeding assembly. Background Technology

[0002] In the production and processing of aluminum frames, when aluminum frames arrive, in order to avoid friction and scratches between the frames, isolation paper strips are placed between each layer of frames. These isolation paper strips are located at both ends of the length of the frame. When transferring the aluminum frames, the isolation paper strips need to be removed first.

[0003] Existing technologies use paper suction cups to pick up release paper strips; however, relying solely on these suction cups has several drawbacks. In practice, the release paper strips between the aluminum frames are thin, smooth, and flexible, making it difficult for the suction cup to maintain a stable adsorption force. External interference, such as vibration during handling, can easily cause adsorption failure. Furthermore, due to long-term stacking and compression, the release paper is prone to wrinkles and deformation, turning the originally smooth adsorption surface into an uneven surface, significantly increasing the difficulty of precise suction. Analyzing the working principle of the suction cup, it relies on negative pressure for adsorption, but the thinness of the release paper makes it prone to loose adhesion, leading to air leakage and insufficient negative pressure, thus affecting the adsorption effect. Finally, considering the actual operating environment, dust, static electricity, and other factors in factory workshops can adhere to the release paper and suction cup surfaces, altering their physical properties and further reducing adsorption performance.

[0004] Furthermore, for some larger or irregularly shaped aluminum frames, the positioning and picking of the release paper becomes even more difficult.

[0005] Therefore, relying solely on the isolation paper suction cup is insufficient to meet the demand for efficient and stable feeding, and a more effective solution is urgently needed to improve this situation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this application is to provide an aluminum frame feeding assembly and an automatic feeding device for aluminum frames of photovoltaic panels, which can more stably remove the insulating paper strips.

[0007] The above-mentioned objective of this application is achieved through the following technical solution:

[0008] An aluminum frame feeding assembly includes a suction assembly, a multi-degree-of-freedom robotic arm, and a paper separator suction cup. The suction assembly is mounted on the multi-degree-of-freedom robotic arm, and the paper separator suction cup is mounted on the suction assembly. The assembly also includes a paper separator gripper, which includes two grippers arranged opposite each other and a cylinder that drives the two grippers to move closer or further apart. The cylinder is connected to the suction assembly.

[0009] This application further specifies that both clamps are arc-shaped, the working surface of the clamps is provided with anti-slip texture, and the clamping direction of the clamps is perpendicular to the suction direction of the separator paper suction cup.

[0010] This application further provides that the end of the clamp is provided with a flexible buffer layer, the flexible buffer layer being made of silicone or polyurethane.

[0011] This application further specifies that the working surface of the chuck is a serrated or wavy structure for increasing friction with the release paper.

[0012] This application is further configured such that the number of the isolation paper suction cups and the isolation paper grippers are both four, and the four isolation paper suction cups and the four isolation paper grippers are respectively disposed on both sides of the length direction of the multi-degree-of-freedom manipulator.

[0013] This application further specifies that the isolation paper suction cup is a vacuum suction cup, and the suction area of ​​the isolation paper suction cup is larger than the clamping area of ​​the isolation paper gripper.

[0014] The present application further specifies that the suction component includes a plurality of feeding suction cups, the plurality of feeding suction cups are arranged in a rectangular arrangement to form several suction cup groups, and the feeding suction cups in each suction cup group are arranged along a straight line.

[0015] This application further specifies that the feeding suction cup is a sponge suction cup.

[0016] An automatic feeding device for aluminum frames of photovoltaic panels includes the aforementioned aluminum frame feeding component and a horizontal moving component. The multi-degree-of-freedom manipulator is mounted on the horizontal moving component, and the horizontal moving component drives the multi-degree-of-freedom manipulator to move in a straight line.

[0017] In summary, the beneficial technical effects of this application are as follows:

[0018] 1. The release paper gripper in this application can firmly hold the release paper by means of two relatively set clamps. The clamping method can effectively avoid adsorption failure caused by the release paper being thin, smooth and soft, and easily wrinkled and deformed. It greatly improves the stability of the release paper during the picking and handling process and reduces the risk of the release paper falling off.

[0019] 2. This application uses a clamping method, which has little impact on dust and static electricity in the factory workshop. Even if the physical properties of the release paper surface are changed due to dust and static electricity, the clamp can still stably grasp the release paper by mechanical clamping, adapting to more complex actual operating environments.

[0020] 3. Even when facing irregularly shaped aluminum frames, the clamp of this application can more flexibly and accurately position and pick up the release paper by adjusting the position and clamping force, which makes up for the shortcomings of release paper suction cups in terms of positioning and picking up when dealing with such frames, and meets the feeding needs of aluminum frames of different specifications.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-3 As shown, an aluminum frame feeding assembly and an automatic feeding device for aluminum frames of photovoltaic panels are disclosed. The aluminum frame feeding assembly includes a suction assembly 1, a multi-degree-of-freedom manipulator 4, and a paper suction cup 2. The suction assembly 1 is mounted on the multi-degree-of-freedom manipulator 4, and the paper suction cup 2 is mounted on the suction assembly 1. The assembly also includes a paper gripper 3, which includes two grippers 31 arranged opposite to each other and a cylinder that drives the two grippers 31 to move closer or further apart. The cylinder is connected to the suction assembly 1.

[0027] Specifically, the suction component 1 is reliably installed at the end of the robotic arm of the multi-degree-of-freedom robot 4 via a specific connecting device, such as bolt fastening or slot docking, ensuring that the suction component 1 will not loosen or shift during the robot's movement. The release paper suction cup 2 is fixed to the suction component 1 using a suitable mounting base, so that the suction surface of the suction cup can be accurately aligned with the release paper between the aluminum frames. The cylinder of the release paper gripper 3 is connected to the suction component 1 via a matching bracket or connector, ensuring that the opening and closing direction of the gripper 31 is adapted to the position of the release paper, facilitating precise gripping of the release paper.

[0028] More specifically, the multi-degree-of-freedom manipulator 4 uses a common six-axis industrial robot as its main component, consisting of a base, rotary joints, linkages, motors, and reducers. The motors and reducers work together to provide power to each joint, enabling the manipulator to move in six degrees of freedom in space: linear motion along two mutually perpendicular directions in the horizontal plane and the vertical direction, as well as rotational motion around two mutually perpendicular directions in the horizontal plane and the vertical direction.

[0029] The suction assembly 1 adopts a vacuum adsorption structure, mainly including a vacuum generator, a suction cup mounting plate, suction cups, and connecting pipes. The vacuum generator is fixed to the end of the robotic arm of the multi-degree-of-freedom robot 4 via a mounting bracket. The suction cup mounting plate is bolted to the bottom of the vacuum generator to ensure a secure connection. The suction cups are made of silicone, which has good flexibility and sealing properties. Multiple suction cups are reasonably distributed on the suction cup mounting plate according to the size and shape of the aluminum frame to ensure stable adsorption of the aluminum frame. The connecting pipes are made of high-pressure resistant and corrosion-resistant rubber tubing, connecting the vacuum generator and the suction cups to ensure the sealing and stability of the vacuum system.

[0030] The release paper suction cup 2 has a flat structure and is installed on both sides of the suction cup mounting plate. It is made of a special soft rubber material, which ensures good adsorption performance for the release paper while preventing damage to the release paper during adsorption. The release paper suction cup 2 is also connected to the vacuum generator. The adsorption surface of the suction cup is designed with fine texture to increase the friction and adsorption force between the suction cup and the release paper.

[0031] The cylinder of the paper gripper is mounted on both sides of the suction cup mounting plate via a matching bracket or connector, ensuring that the opening and closing direction of the gripper head 31 matches the position of the release paper for precise gripping. The cylinder is a pneumatic cylinder, using compressed air as a power source, offering advantages such as fast response and stable output force. The two grippers 31 are made of stainless steel with an anti-slip surface to increase the gripping force on the release paper. The opening and closing stroke of the gripper head 31 can be adjusted according to the thickness and size of the release paper to ensure secure gripping of release papers of different specifications.

[0032] like Figure 2 The release paper gripper 3 shown is provided with a cylinder connection port 32 for connecting the cylinder. The cylinder is selected as a hydraulic cylinder or a pneumatic cylinder, which drives the two grippers 31 to move closer and further apart, thereby realizing the gripping and releasing of the release paper.

[0033] The cylinder connection port 32 on the release paper gripper 3 adopts a standardized interface design to accommodate different types of hydraulic or pneumatic cylinders. A sealing gasket is installed inside the connection port to ensure the sealing of the hydraulic or pneumatic system after the cylinder is connected, preventing liquid or gas leakage from affecting the driving effect. The shape of the connection port matches the connection end of the cylinder, for example, using a flange connection or threaded connection, and the cylinder is securely fixed to the release paper gripper 3 by tightening bolts or nuts.

[0034] In a preferred embodiment, a hydraulic cylinder is used as the cylinder body. The hydraulic cylinder mainly consists of a cylinder barrel, piston, piston rod, end caps, and other components. The cylinder barrel is the main body of the hydraulic cylinder, and its internal machining precision is high to ensure that the piston can slide smoothly within it. The piston divides the cylinder barrel into two chambers: a rodless chamber and a rod chamber. One end of the piston rod is connected to the piston, and the other end extends out of the cylinder barrel and is connected to the clamp 31. The end caps are installed at both ends of the cylinder barrel, serving a sealing and fixing function. In the release paper gripper 3, the two clamps 31 are rotatably connected to the extended ends of the piston rod, and the clamps 31 move closer and further apart through the extension and retraction of the piston rod. When it is necessary to clamp the release paper, the hydraulic system is activated, and the hydraulic pump delivers hydraulic oil through pipelines to the rodless chamber of the hydraulic cylinder. Under the pressure of the hydraulic oil, the piston pushes the piston rod to extend, thereby causing the two clamps 31 to move closer to each other and clamp the release paper. When the release paper needs to be released, the hydraulic system controls the hydraulic oil to flow back from the rodless chamber to the oil tank, while oil enters the rod chamber, causing the piston rod to retract and the clamps 31 to move away from each other, thus releasing the release paper. By adjusting the relief valve and throttle valve in the hydraulic system, the flow rate and pressure of the hydraulic oil can be controlled, thereby precisely controlling the movement speed and clamping force of the clamps 31 to accommodate release papers of different thicknesses and materials.

[0035] The newly added release paper gripper 3, through two opposing grippers 31 and a cylinder that drives the grippers 31, can firmly hold the release paper. Compared to relying solely on the release paper suction cup 2, the gripping method of the grippers 31 can effectively avoid adsorption failure caused by the release paper being thin, smooth, soft, and easily wrinkled and deformed, greatly improving the stability of the release paper during picking and handling, and reducing the risk of the release paper falling off.

[0036] Factors such as dust and static electricity present in the factory workshop that affect the adsorption performance of the release paper suction cup 2 are less affected by them. Even if the physical properties of the release paper surface are changed due to dust, static electricity, etc., the gripper can still stably grasp the release paper by mechanical clamping, adapting to more complex actual operating environments.

[0037] When dealing with aluminum frames that are large in size or irregular in shape, the release paper gripper 3 can adjust the position and gripping force of the gripper head 31 to more flexibly and accurately position and pick up the release paper, making up for the shortcomings of the release paper suction cup 2 in terms of positioning and picking up when dealing with such frames, and meeting the feeding needs of aluminum frames of different specifications.

[0038] The stable and reliable release paper picking method reduces repetitive operations and downtime caused by release paper picking failures, making the aluminum frame feeding process smoother and more efficient. Overall, it improves the efficiency of aluminum frame production and processing, helping companies increase production capacity and reduce production costs.

[0039] Further, see Figure 2 Both chucks 31 are arc-shaped, and the working surface 33 of the chucks 31 is provided with anti-slip texture. The clamping direction of the chucks 31 is perpendicular to the suction direction of the separator paper suction cup 2.

[0040] The two grippers 31 are arc-shaped, their curvature adapting to the common positions of the release paper strip within the aluminum frame, facilitating clamping. On the working surface 33 of the grippers 31, anti-slip textures are created using a special processing technique, such as knurling or laser etching. The depth and spacing of these anti-slip textures are precisely calculated, effectively increasing the friction between the gripper and the release paper to prevent slippage during clamping without damaging the release paper. The grippers 31 are installed on the cylinder drive end of the release paper gripper 3, and an adjustable connection structure ensures that the clamping direction of the grippers 31 is perpendicular to the suction direction of the release paper suction cup 2. During installation, high-precision measuring tools are used for calibration to ensure that the perpendicularity accuracy error is controlled within a minimal range to meet the precise operation requirements of the equipment.

[0041] The multi-degree-of-freedom robotic arm 4 moves the suction component 1, the release paper suction cup 2, and the release paper gripper 3 to the aluminum frame storage area according to a preset program and trajectory. During this process, the robotic arm's movement speed and acceleration are optimized according to the actual working environment and equipment performance to ensure that it reaches the target position quickly and smoothly.

[0042] Upon reaching the designated position, the release paper gripper 3 activates first. The cylinder drives the two grippers 31 to move closer together. Because the grippers 31 are arc-shaped and the working surface 33 has anti-slip texture, they can stably hold the release paper at both ends along the length of the aluminum frame. Simultaneously, because the gripping direction of the grippers 31 is perpendicular to the suction direction of the release paper suction cup 2, it is easier to grip vertically bent release paper pieces during the gripping action. Specifically, the gripping direction of the grippers 31 refers to the direction in which the two grippers 31 move closer together, and the suction direction refers to the direction of the attraction force generated by the suction cup. Since most aluminum frames have vertical bends, the release paper pieces also have bends. The release paper gripper 3 and the release paper suction cup 2 fix the release paper from two directions, making it easier to grip.

[0043] After the release paper gripper 3 completes its gripping, the suction component 1 is activated, and the release paper suction cup 2 begins to work, using negative pressure to adsorb the release paper. Since the gripper 31 has firmly fixed both ends of the release paper, the release paper suction cup 2 can more easily adsorb the release paper, reducing adsorption failures caused by uneven release paper or unstable adsorption surfaces.

[0044] In a preferred embodiment, the end of the clamp 31 is provided with a flexible buffer layer, which is made of silicone or polyurethane. A silicone or polyurethane material of suitable thickness is selected to make the flexible buffer layer, generally controlled between 3mm and 5mm. The flexible buffer layer is precisely adhered to the end of the clamp 31 through a molding process. During the adhesion process, a special adhesive or bonding agent is used to ensure that the buffer layer is tightly bonded to the clamp 31 and will not fall off during use. After installation, the clamp 31 and the flexible buffer layer are inspected to ensure that the surface of the buffer layer is flat, free of bubbles and wrinkles, and that the buffer layer can bear force evenly when the clamp 31 holds the release paper.

[0045] The flexible buffer layer effectively cushions the impact force when the clamp 31 holds the release paper, preventing damage to the release paper due to rigid contact of the clamp 31, ensuring the integrity of the release paper during handling, and providing conditions for subsequent use of the release paper. Whether for thin paper release paper or soft plastic film release paper, the flexible buffer layer adapts well, expanding the applicability of the aluminum frame feeding assembly to different types of release paper.

[0046] In another preferred embodiment, the working surface 33 of the chuck 31 has a serrated or wavy structure to increase friction with the release paper. For the serrated structure, uniformly distributed serrations are machined on the working surface 33 of the chuck 31 using precision machining or electrical discharge machining. For the wavy structure, a continuous wavy shape is formed on the working surface 33 of the chuck 31 using die stamping or CNC machining.

[0047] This application further specifies that there are four isolation paper suction cups 2 and four isolation paper grippers 3, with the four isolation paper suction cups 2 and four isolation paper grippers 3 respectively located on both sides of the length direction of the multi-degree-of-freedom robot arm 4. Figure 1 and Figure 2 As shown, since the isolation paper strips are located at both ends of the frame's length direction, the isolation paper suction cups 2 and the isolation paper grippers 3 are distributed on both sides of the length direction of the multi-degree-of-freedom robot arm 4, i.e. Figure 1 The top and bottom sides of the middle.

[0048] Furthermore, the separator paper suction cup 2 is a vacuum suction cup, and its suction area is larger than that of the separator paper gripper 3. The larger suction area better covers the separator paper, increasing the effective range of the adsorption force. Even if the separator paper deforms or becomes uneven due to long-term stacking or transportation vibrations, the larger suction area ensures sufficient adsorption surface, thereby improving adsorption stability and reducing the risk of feeding failure due to weak adsorption.

[0049] Furthermore, the suction component 1 includes multiple feeding suction cups, which are arranged in a rectangular array to form several suction cup groups 11, and the feeding suction cups in each suction cup group 11 are arranged in a straight line.

[0050] Specifically, a sponge suction cup is selected for the feeding suction cup.

[0051] like Figure 3 As shown, an automatic feeding device for aluminum frames of photovoltaic panels is provided, including the aforementioned aluminum frame feeding component and a horizontal moving component 5. A multi-degree-of-freedom manipulator 4 is mounted on the horizontal moving component 5, and the horizontal moving component 5 drives the multi-degree-of-freedom manipulator 4 to move in a straight line.

[0052] Specifically, the horizontal movement component 5 includes a track system, a drive unit, connectors, and mounting brackets. The track system uses a high-precision linear guide rail, which consists of a track and a slider. The track is made of high-strength aluminum alloy, and its surface undergoes precision grinding and hardening treatment to ensure its straightness and wear resistance. The slider is installed at the bottom of the multi-degree-of-freedom robot 4, and through internal rolling elements, such as balls or rollers, it cooperates with the track to achieve smooth linear motion. The length of the track is determined according to the working area of ​​the automatic feeding device for photovoltaic panel aluminum frames and the movement requirements of the multi-degree-of-freedom robot 4. Preferably, the track length is 2m to 5m to ensure that the multi-degree-of-freedom robot 4 can cover the aluminum frame storage area and subsequent processing stations.

[0053] The drive mechanism for propelling the multi-degree-of-freedom (DOF) robot 4 along linear motion utilizes a servo motor paired with a ball screw. The servo motor offers high-precision position control and rapid response, enabling precise control of the robot 4's movement speed and position. The ball screw consists of a screw, a nut, and balls. The servo motor's output shaft is connected to the screw; when the motor rotates, the screw drives the nut in a linear motion, which is then fixedly connected to the multi-DOF robot 4, thus achieving linear movement. To ensure transmission efficiency and accuracy, the ball screw's lead and pitch must be appropriately selected based on the actual load and movement speed requirements.

[0054] The multi-degree-of-freedom robot 4 is connected to the slider of the horizontal movement component 5 via a specially designed mounting bracket. The mounting bracket is made of high-strength steel and is machined to ensure the flatness and perpendicularity of its mounting surface, thus guaranteeing the stability and accuracy of the multi-degree-of-freedom robot 4 after installation. High-strength bolts and nuts are used for the connecting parts to firmly connect the mounting bracket and the slider together, preventing loosening during movement.

[0055] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
