Description

An automatic corner bracket pressing device for photovoltaic panel frames Technical Field

[0001] This utility model relates to the field of photovoltaic panel frame technology, and in particular to an automatic corner code pressing device for photovoltaic panel frames. Background Technology

[0002] Corner brackets are crucial components used for connecting and reinforcing structures. In photovoltaic (PV) panel frames, they play a key role, connecting the various edges of the frame to ensure structural stability and provide a reliable support foundation for the PV panels. PV panels are exposed to the outdoors for extended periods, enduring wind, sun, rain, and other natural environmental conditions. Therefore, the stability of the frame is paramount, and as the core component for frame connection, the installation quality of the corner brackets directly affects the safety and lifespan of the entire PV panel system.

[0003] In the production process of photovoltaic panel frames, the corner bracket pressing process is extremely important. Traditional corner bracket pressing equipment mostly relies on simple mechanical structures to complete the pressing action, but a series of problems have been exposed during long-term operation.

[0004] Taking the pneumatic-driven moving base pressing as an example, the lack of suitable lubrication for the pressing components makes them highly susceptible to damage due to friction during sliding between the moving base and the optical axis. This not only degrades the stability of the device and affects the pressing accuracy but also necessitates frequent shutdowns for maintenance, severely slowing down production efficiency. Furthermore, traditional pressing devices lack pressure-holding functions at the pressing block location, making it difficult to precisely control and maintain pressure during pressing. Excessive pressure can easily damage the pressing block or photovoltaic panel frame, leaving dents on the frame surface or even causing cracks, significantly impacting the finished product quality and yield of the photovoltaic panel frame.

[0005] Therefore, we propose an automatic corner bracket pressing device for photovoltaic panel frames. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies. Common pneumatic rod-driven pressing devices for moving seats suffer from a lack of lubrication, resulting in high friction between the moving seat and the optical shaft, accelerated wear, unstable operation, and reduced pressing accuracy. Furthermore, the pressing block lacks a pressure-holding function, making pressure difficult to control. Excessive pressure can easily cause dents and cracks in the frame, reducing the quality and yield of finished products.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An automatic pressing device for corner brackets of a photovoltaic panel frame includes a base, a top seat on the top of the base, two linear optical axes between the base and the top seat, a movable seat between the two linear optical axes, and a plurality of mounting cavities at the bottom of the movable seat. An elastic pressing component is provided inside each mounting cavity. The elastic pressing component is used to maintain pressure when the movable seat presses down, preventing damage to the product.

[0012] As a preferred embodiment of this utility model, the oil inlet pipe is used to absorb lubricating fluid, and the fluid is delivered into the movable seat through the oil storage chamber, the oil pump and the connecting parts, so that the movable seat and the linear optical axis are lubricated.

[0013] As a preferred embodiment of this utility model, the top of the compression spring is fixed to the top of the mounting cavity, and the bottom is fixed to the pressing block.

[0014] As a preferred embodiment of this utility model, a fixed mounting base is provided on the top of the equipment base and below the movable seat. A photovoltaic panel frame body is mounted on the fixed mounting base. An angle bracket body is provided inside the photovoltaic panel frame body.

[0028] Example

[0029] As shown in Figures 1-4, this utility model provides a technical solution: the automatic pressing device for photovoltaic panel frame corner brackets, the equipment base 1 is the supporting foundation of the entire device, it is welded from thick metal plates, has sufficient strength and stability, and can withstand various forces generated during the operation of the device. On the top of the equipment base 1, the top seat 2 is firmly installed by multiple high-strength bolts, so as to ensure that the two are firmly connected and their relative positions are accurate.

[0030] Between the equipment base 1 and the top seat 2, two linear optical axes 3 are arranged in parallel. The linear optical axes 3 are made of special alloy steel and are precision machined to have extremely small errors in cylindricity and straightness, ensuring excellent guiding accuracy. The surface of the optical axes is also hardened to improve its wear resistance and extend its service life. The movable seat 4 is located between the two linear optical axes 3. The movable seat 4 is equipped with a slider that is compatible with the linear optical axes 3. The slider is usually made of self-lubricating material, such as a composite material containing graphite or molybdenum disulfide, to reduce friction with the optical axes and at the same time have good wear resistance, ensuring that the movable seat 4 slides smoothly and steadily up and down along the linear optical axes 3 and accurately performs the corner code pressing action. Compared with traditional pressing devices, this architecture greatly reduces the deviation during the movement process through the reasonable design of the layout and connection of each component, providing a stable and reliable foundation for subsequent pressing operations.

[0031] The elastic pressing assembly is installed in the pre-drilled mounting cavity 5 at the bottom of the movable base 4. These mounting cavities 5 are precisely sized and positioned to accommodate the installation and operation requirements of the elastic pressing assembly.

[0032] As the core component of the elastic pressing assembly, the pressing block 8 is made of high-strength alloy steel and undergoes multiple heat treatment processes, giving it excellent strength and toughness. It can withstand significant pressure without deformation. Four dampers 6 are evenly distributed and firmly fixed on the top of the pressing block 8. The dampers 6 employ the principle of hydraulic damping, filled with high-viscosity damping oil. Damping force is generated by the movement of a piston in the damping oil. A compression spring 7 is tightly fitted on the outside of each damper 6. The compression spring 7 is made of high-quality spring steel wire and undergoes a special heat treatment process, giving it a stable elastic coefficient. It can produce uniform elastic deformation under pressure. The top of the compression spring 7 is fixed to the top of the mounting cavity 5 by welding or high-strength bolts, while the bottom is tightly connected to the top of the pressing block 8, ensuring effective pressure transmission and buffering during the pressing process.

[0033] When the movable seat 4 begins to press down under the drive of the pneumatic rod, the pressing block 8 first contacts the corner bracket body 17. As the pressing stroke increases, the pressure gradually increases, and the compression spring 7 begins to be compressed. At the same time, the damper 6 begins to play its role. Due to the viscous resistance of the damping oil, the piston's movement speed inside the damper 6 slows down, thereby reducing the compression rate of the compression spring 7. This design, in which the spring and damper 6 work together, utilizes the elasticity of the spring to buffer the pressure and avoids impact damage to the photovoltaic panel frame caused by excessive pressure. The damper 6 precisely controls the rate of pressure change, ensuring a smooth pressing process and uniform and controllable pressure. Compared with the traditional non-elastic pressing method, it effectively prevents problems such as dents on the frame surface and cracks in the internal structure caused by improper pressure control, ensuring the pressing quality of the corner bracket and significantly improving the quality and pass rate of the finished product.

[0034] At the bottom of the pressing block 8, a limiting block 9 is provided. The limiting block 9 is generally made of a high-hardness, wear-resistant material, such as hard alloy or surface-hardened steel. Its shape and size are specially designed according to the shape of the corner bracket body 17 and the pressing requirements. During the pressing process, the limiting block 9 is in close contact with the side wall of the corner bracket body 17. Through mechanical limiting, the installation position of the corner bracket in the photovoltaic panel frame is ensured to be accurate, further improving the pressing accuracy.

[0035] The movable seat 4 has an integrated automatic lubrication component inside both side walls, which greatly improves the stability and service life of the device.

[0036] The oil reservoir 11 of the automatic lubrication assembly is used to store lubricating fluid. It is usually made of corrosion-resistant metal or high-strength plastic material and has good sealing performance to prevent lubricating fluid leakage. The oil reservoir 11 is located above the assembly, and a reliable oil pump 12 is installed at the bottom. The oil pump 12 can accurately control the pumping flow and pressure of the lubricating fluid according to the operating status of the device. Common types include electric gear pumps or plunger pumps.

[0037] One end of the oil inlet pipe 14 extends into the oil storage chamber 11 and is immersed in the lubricating fluid. A fine filter screen is installed at the pipe opening to prevent impurities in the lubricating fluid from entering the pipe and to ensure the cleanliness of the lubricating fluid. When the device is started, the oil pump 12 works, and the internal gears or plungers rotate at high speed under the drive of the motor, generating a strong suction force to draw the lubricating fluid in the oil storage chamber 11 into the oil inlet pipe 14. The oil inlet pipe 14 is made of corrosion-resistant and high-pressure resistant rubber or metal hose and is tightly connected to the output end of the oil pump 12 through a high-precision connector 13. The connector 13 not only connects the pipe but also has good sealing and pressure resistance performance to ensure that there is no leakage of lubricating fluid during pumping.

[0038] After being pressurized by the oil pump 12, the lubricating fluid enters the interior of the movable seat 4 through the connector 13, and is then delivered to the connection point between the movable seat 4 and the linear optical axis 3 by the output pipe 10 installed on the side wall of the movable seat 4. The outlet of the output pipe 10 is precisely designed and positioned to accurately spray the lubricating fluid onto the sliding contact surface between the movable seat 4 and the linear optical axis 3. This design, through the active pumping of the lubricating fluid by the oil pump 12, achieves continuous and precise lubrication of the sliding parts between the movable seat 4 and the linear optical axis 3. Compared with the traditional method of manually applying grease periodically, the automatic lubrication component significantly improves the timeliness and stability of lubrication. The lubricant can cover the sliding parts in real time and evenly, effectively reducing the coefficient of friction, reducing component wear, and improving the stability of the device operation and the pressing accuracy. At the same time, due to the reduction of component wear, the equipment failure rate is greatly reduced, avoiding frequent downtime for maintenance and significantly improving production efficiency. When placing the photovoltaic panel frame body 15, the operator can align a specific part of the frame with the fixed mounting base 16, using the shape and position of the fixed mounting base 16 as a positioning reference to ensure that the frame is accurately placed on the fixed mounting base 16 at the top of the equipment base 1, providing a good initial position foundation for subsequent pressing operations.

[0039] Overall Workflow

[0040] Preparation stage: The operator first moves the photovoltaic panel frame body 15, which has undergone strict quality inspection, to the fixed mounting base 16 on the top of the equipment base 1. The fixed mounting base 16 is designed with a specific positioning structure, such as positioning pins or slots, which can closely cooperate with the corresponding parts of the photovoltaic panel frame body 15 to ensure that the frame is installed in an accurate and stable position. Then, the corner bracket body 17 is carefully placed inside the photovoltaic panel frame body 15 according to the predetermined installation direction and position.

[0041] Lubrication stage: After the device is powered on and started, the controller 18 starts each component to work. The oil pump 12 in the automatic lubrication assembly starts working immediately. The oil pump 12 runs at a stable speed according to the preset working parameters and draws lubricating fluid from the oil storage chamber 11 through the oil inlet pipe 14. Under the pressure of the oil pump 12, the lubricating fluid is transported to the connection between the moving seat 4 and the linear optical axis 3 through the connector 13 and the output pipe 10 to lubricate the sliding parts of the two, reduce friction, and prepare for stable operation in the pressing stage.

[0042] Pressing stage: Driven by the pneumatic rod, the movable seat 4 slides smoothly downward along the linear optical axis 3. The pressing block 8 of the elastic pressing assembly contacts the corner code body 17 first. As the pressing continues, the compression spring 7 is compressed, and the damper 6 slows down the spring compression speed to achieve stable pressure holding. During the pressing process, the limiting block 9 contacts the side wall of the corner code body 17 to limit the corner code position and ensure accurate installation until the corner code pressing operation is completed.

[0043] Final stage: After the pressing is completed, the movable seat 4 rises and resets under the action of the pneumatic rod, returning to the initial position. At this time, the automatic lubrication component continues to work, preparing for the next pressing operation in advance, ensuring that the device can operate continuously, efficiently and stably.
