Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket profile production technology, and more specifically, it relates to a surface cleaning device for photovoltaic bracket profile production. Background Technology

[0002] As the core structural component supporting photovoltaic modules, the surface cleanliness of existing photovoltaic bracket profiles directly affects the processing quality of subsequent processes such as spraying and assembly, as well as the service life of the final product. During the production processes such as rolling, cutting, and handling of photovoltaic bracket profiles, impurities such as metal shavings, dust, and oil stains are easily attached to the surface. If these impurities are not thoroughly cleaned, they will cause the coating to not adhere tightly to the surface of the profile during the spraying process, resulting in defects such as coating peeling, bulging, and pinholes, which will reduce the corrosion resistance of the photovoltaic bracket. Currently, the surface cleaning devices used in the production of photovoltaic bracket profiles still have many problems that need to be solved in terms of structural design and functional adaptability.

[0003] First, traditional dust removal devices mostly use fixed-position cleaning. When producing photovoltaic bracket profiles of different specifications, the fixed dust removal structure is difficult to cover all areas of the profile surface, especially the corners and grooves of the profile, where impurities are easily left behind, requiring manual secondary cleaning. This not only increases the labor intensity of operators but also reduces the overall production efficiency. Secondly, the existing dust removal devices often have independent cleaning and air-jetting functions. Some devices rely solely on brush rollers for mechanical cleaning, which has limited cleaning effect on dust or fine debris with strong adhesion. Other devices only use high-pressure air jets, which can blow away surface dust, but it is difficult to completely remove impurities embedded in the texture or grooves of the profile surface, resulting in incomplete dust removal. Furthermore, most of the equipment uses manual fixing of the profiles, which is not only cumbersome to operate, but also difficult to control the fixing force, which prolongs the production preparation time and restricts the continuous operation efficiency of the production line.

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a surface cleaning device for photovoltaic bracket profile production, so as to solve the technical problems mentioned in the background art, which mostly adopt fixed position cleaning and incomplete cleaning.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A surface cleaning device for photovoltaic bracket profile production includes a processing plate. Support rods are provided at both ends of the sidewall of the processing plate, and a screw is arranged between the support rods. A movable block is threadedly connected to the screw. A first motor is provided on the outer wall of one of the support rods, and one end of the screw is connected to the output end of the first motor. Limiting plates are provided on both sides of the screw, and the limiting plates are fitted and slidably connected to the sidewall of the movable block. A high-pressure air nozzle is provided at the lower end of the movable block, and an output pipe is provided at the upper end of the high-pressure air nozzle. A high-pressure air blowing cleaner is provided at one end of the output pipe. A fixing component is provided on the inner side of the support rod, and a cleaning component is provided on the sidewall of the processing plate.

[0006] The present invention is further configured such that the cleaning assembly includes an electromagnetic slide rail, a magnetic slider, a cylinder, a support frame, and a cleaning roller. The electromagnetic slide rail is symmetrically arranged at both ends of the side wall of the processing plate. The magnetic slider is on the electromagnetic slide rail and is electromagnetically slidably connected to it. The cylinder is on the upper end of the magnetic slider, and the cleaning roller is on the upper end of the cylinder. The cleaning roller is located inside the support frame. A drive motor is provided on one side of the cleaning roller, which can adapt to different specifications of profiles. At the same time, the drive motor drives the cleaning roller to actively clean, improve the dust removal efficiency, and reduce the residue of impurities.

[0007] The present invention is further configured such that the fixing component includes an electric push rod and a fixing block, the electric push rod is located at the lower end of the side wall of the support rod, and the fixing block is located at one end of the electric push rod, which can automatically push the fixing block to clamp the profile without manual fixing.

[0008] The present invention is further configured such that a placement box is provided at the lower end of the processing plate, a drawer is provided inside the placement box, the drawer is slidably connected to the placement box, a handle is provided on the front side wall of the drawer, and a collection port is provided on the processing plate, which can guide the cleaned impurities to fall into the drawer inside the placement box, so as to realize the centralized collection of impurities and avoid dust scattering and polluting the environment.

[0009] The present invention is further provided with buffer blocks at both ends of the electromagnetic slide rail. The buffer blocks are made of rubber to prevent the magnetic slider from directly colliding with the end of the slide rail and reduce equipment wear.

[0010] The present invention is further provided with wear-resistant coatings on both sides of the movable block. The wear-resistant coatings are made of polytetrafluoroethylene, which can enhance the wear resistance of the two sides of the movable block and reduce frictional loss when the movable block slides with the limiting plate.

[0011] The present invention is further provided with shock-absorbing pads at the four lower corners of the processing plate. The shock-absorbing pads are made of rubber and can absorb vibrations and reduce noise during operation of the equipment.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a surface cleaning device for photovoltaic bracket profile production, which has the following beneficial effects: 1. When the first motor drives the screw to rotate, the moving block connected to the screw threadedly moves horizontally along the screw. The limit plates on both sides ensure that the moving block slides stably without deviating, so that the air nozzle can cover different areas of the profile surface, accurately blowing away surface dust and small impurities in the corners and gaps. The cleaning roller in the cleaning component rotates actively under the drive of the drive motor to mechanically clean the profile surface, which can remove metal debris and stubborn impurities with strong adhesion.

[0013] 2. At the same time, the magnetic slider and cylinder can flexibly adjust the height and position of the cleaning roller to adapt to profiles of different thicknesses, avoiding the limitations of traditional single dust removal methods, ensuring that impurities on the surface, edges and corners and textures of the profiles can be thoroughly removed, meeting the strict requirements of subsequent spraying and assembly processes for surface cleanliness.

[0014] 3. The collection port on the processing plate works in conjunction with the lower placement box and drawer to form a complete impurity collection system, preventing impurities from spreading to the workshop environment and causing pollution, thus ensuring the cleanliness of the production environment; the drawer and placement box are slidably connected and have handles, allowing operators to easily pull out the drawer to clean impurities, making operation convenient and reducing the workload of subsequent environmental cleaning, thus balancing production efficiency and environmental protection requirements.

[0020] Please see Figure 1-5 A surface cleaning device for photovoltaic bracket profile production includes a processing plate 1. Support rods 2 are provided at both ends of the upper sidewall of the processing plate 1. A screw 3 is provided between the support rods 2. A movable block 4 is threadedly connected to the screw 3. A first motor 5 is provided on the outer sidewall of one of the support rods 2. One end of the screw 3 is connected to the output end of the first motor 5. Limiting plates 6 are provided on both sides of the screw 3. The limiting plates 6 are fitted and slidably connected to the sidewall of the movable block 4. A high-pressure jet nozzle 7 is provided at the lower end of the movable block 4. An output pipe 8 is provided at the upper end of the high-pressure jet nozzle 7. A high-pressure air blowing cleaner 9 is provided at one end of the output pipe 8. A fixing component is provided on the inner side of the support rod 2. A cleaning component is provided on the upper sidewall of the processing plate 1.

[0021] The cleaning assembly includes an electromagnetic slide rail 10, a magnetic slider 11, a cylinder 12, a support frame 13, and a cleaning roller 14. The electromagnetic slide rail 10 is symmetrically arranged at both ends of the upper side wall of the processing plate 1. The magnetic slider 11 is on the electromagnetic slide rail 10 and is electromagnetically slidably connected to it. The cylinder 12 is on the upper end of the magnetic slider 11. The cleaning roller 14 is on the upper end of the cylinder 12. The cleaning roller 14 is inside the support frame 13. A drive motor 15 is provided on one side of the cleaning roller 14.

[0022] The fixing assembly includes an electric push rod 16 and a fixing block 17. The electric push rod 16 is located at the lower end of the side wall of the support rod 2, and the fixing block 17 is located at one end of the electric push rod 16.

[0023] The processing plate 1 is provided with a placement box 18 at its lower end. The placement box 18 is provided with a drawer 19. The drawer 19 is slidably connected to the placement box 18. The drawer 19 is provided with a handle 20 on its front and side walls. The processing plate 1 is provided with a collection port.

[0024] In this embodiment, the first step is to fix the profile. The operator places the photovoltaic bracket profile to be cleaned on the upper surface of the processing plate 1, ensuring that both ends of the profile correspond to the fixing components inside the support rod 2. Then, the electric push rod 16 in the fixing component is activated. The electric push rod 16 pushes the fixing block 17 at one end towards the profile until the fixing blocks 17 on both sides are tightly attached to the side wall of the profile, firmly clamping the profile between the fixing plates. This prevents the profile from shifting or shaking during the subsequent cleaning process, ensuring the cleaning accuracy. After the profile is fixed, the high-pressure air blower 9 is turned on. The compressed airflow is delivered to the high-pressure jet nozzle 7 at the lower end of the moving block 4 through the output pipe 8; at the same time, the first motor 5 is started, and the output end of the first motor 5 drives the screw 3 between the support rods 2 to rotate. The moving block 4, which is threadedly connected to the screw 3, moves horizontally along the screw 3 under the action of the rotation of the screw 3. During the process, the two side walls of the moving block 4 slide against the limiting plate 6. The limiting plate 6 effectively prevents the moving block 4 from deviating and ensures the stability of the moving trajectory. The high-pressure jet nozzle 7 moves synchronously with the moving block 4 and sprays air from all directions on the surface of the profile and the corner gaps, blowing away surface dust, small debris and other impurities from the profile.

[0025] More specifically, while the air jet cleaning is being performed, the cleaning assembly is activated for mechanical cleaning. The power to the electromagnetic slide rail 10 is turned on, and the electromagnetic slide rail 10 drives the magnetic slider 11 on it to slide along the slide rail. The moving distance of the magnetic slider 11 is adjusted according to the width and position of the profile, so that the cylinder 12 and the support frame 13 installed on the upper end of the magnetic slider 11 are close to the two sides of the profile. Then the cylinder 12 is activated, and the cylinder 12 extends to push the support frame 13 and the cleaning roller 14 inside the frame to move upward until the surface of the cleaning roller 14 is in close contact with the side wall of the profile. Then the drive motor 15 on one side of the cleaning roller 14 is activated, and the drive motor 15 drives the cleaning roller 14 to rotate. The rotating cleaning roller 14 mechanically cleans the side wall of the profile, removing the metal debris and stubborn impurities with strong adhesion that remain after the air jet cleaning, thus achieving a dual cleaning effect of "air jet + cleaning".

[0026] Please see Figures 1-5 As one embodiment of the buffer block 21: buffer blocks 21 are provided at both ends of the electromagnetic slide rail 10, and the buffer blocks 21 are made of rubber.

[0027] Specifically, when the magnetic slider 11 moves toward both ends of the slide rail due to operation or the inertia of the equipment, if the magnetic slider 11 approaches the end of the slide rail, it will first come into contact with the rubber buffer blocks 21 at both ends of the slide rail. The rubber material itself has good elasticity and can absorb the impact force generated by the movement of the magnetic slider 11 through its own deformation, avoiding direct hard collision between the magnetic slider 11 and the end of the slide rail, and reducing the wear of the magnetic slider 11 and the slide rail.

[0028] Please see Figures 1-5 As one embodiment of the wear-resistant coating: the two side walls of the movable block 4 are provided with a wear-resistant coating, and the material of the wear-resistant coating is polytetrafluoroethylene.

[0029] Specifically, during the sliding process, the coating can significantly reduce the frictional loss between the moving block 4 and the limiting plate 6, and prevent the sidewall of the moving block 4 from wearing and deforming due to long-term friction.

[0030] Please see Figures 1-5 As one embodiment of the shock-absorbing pad 22: shock-absorbing pads 22 are provided at the four lower corners of the processing plate 1, and the shock-absorbing pads 22 are made of rubber.

[0031] Specifically, it can reduce the noise generated by vibration, and at the same time prevent the vibration from being transmitted to the ground and causing damage to the workshop floor, thus providing a stable working environment for the equipment.

[0032] In summary, when using the overall equipment: First, the profile is fixed. The operator places the photovoltaic bracket profile to be cleaned on the processing plate 1, with the cleaning side of the profile facing upwards and both ends corresponding to the fixing components inside the support rod 2. Then, the electric push rod 16 of the fixing component is activated. The electric push rod 16 pushes the fixing block 17 at the end to move towards the profile until the fixing blocks 17 on both sides are firmly attached to the side wall of the profile, and the profile is stably clamped between the two fixing blocks 17 to prevent the profile from shifting during subsequent cleaning and affecting the cleaning effect. After the profile is fixed, the air jet cleaning and mechanical cleaning system is started simultaneously. The high-pressure air blower 9 is turned on, and the high-pressure airflow is delivered to the high-pressure air nozzle 7 at the lower end of the moving block 4 through the output pipe 8. At the same time, the first motor 5 is started, which drives the screw 3 between the support rods 2 to rotate. The moving block 4, which is threaded to the screw 3, moves horizontally along the screw 3. During the movement, the two side walls of the moving block 4 slide against the limiting plate 6, and the limiting plate 6 ensures that the moving block 4 does not deviate. The high-pressure air nozzle 7 moves synchronously with the moving block 4, continuously blowing air onto the upper surface and corner gaps of the profile to remove surface dust and fine debris. Turn on the power to the electromagnetic slide rail 10. The electromagnetic slide rail 10 drives the magnetic slider 11 to slide along the slide rail. Adjust the position of the magnetic slider 11 according to the width of the profile so that the upper cylinder 12, support frame 13 and cleaning roller 14 in the frame are close to the sides of the profile. Then start the cylinder 12. The cylinder 12 extends and pushes the cleaning roller 14 to move upward until the surface of the cleaning roller 14 is in close contact with the side wall of the profile. Then start the drive motor 15. The drive motor 15 drives the cleaning roller 14 to rotate and mechanically clean the side wall of the profile to remove stubborn debris that is difficult to remove by air jet, thus achieving multi-directional cleaning of "air jet + side cleaning". During the dust removal process, all the dust and debris that are cleaned off fall into the lower placement box 18 through the collection port on the processing plate 1 under the action of gravity, and finally accumulate in the drawer 19 inside the box. After the first dust removal is completed, the operator turns off all drive components and controls the electric push rod 16 to retract so that the fixing block 17 is released from the profile. If it is found that there are areas of the profile that have not been cleaned due to the initial clamping position (such as the end of the profile), the position of the profile on the processing plate 1 can be manually adjusted, and the electric push rod 16 can be restarted to push the fixing block 17 to clamp the profile. The above air jetting and cleaning steps are repeated to clean the uncleaned areas and ensure that there are no dead corners on the surface of the profile. After all areas are cleaned, the handle 20 on the front side wall of the drawer 19 is pulled to pull the drawer 19 out of the placement box 18, the collected impurities are emptied, and the drawer 19 is pushed back to its original position to complete a complete dust removal operation and prepare for the next operation.
