Description

Technical Field

[0001] This utility model relates to the field of photovoltaic frame production equipment technology, and more specifically to a photovoltaic frame profile duplex unidirectional conveying mechanism. Background Technology

[0002] On photovoltaic frame production lines, frame profiles need to be precisely and continuously transported from the punching station to the riveting station to form an assembly line operation. Precise positioning and material conveying are essential in this process. Existing photovoltaic module frame profile conveying mechanisms typically employ a roller structure, with several rollers arranged sequentially along the material's travel direction to convey the frame profiles.

[0003] In this conveying method, because the rollers and profiles make point-to-line contact, the adhesion friction between them is relatively small. This can easily lead to slippage, shifting, and misalignment during the conveying process. To prevent shifting and misalignment of the profiles during roller conveying, the inner width of the roller assembly is typically adjusted by adding or removing shims. This ensures the roller assembly's width is greater than the profile's width, maintaining a reasonable clearance between the profile and the side rollers. When the profile cavity thickness changes, the side rollers on both sides of the roller assembly need to be replaced to prevent the profile from shifting laterally off the rollers. By adjusting the roller assembly, shifting and misalignment are restrained, thus achieving smooth material conveying.

[0004] Due to the torsion and bending deformation of the profiles and the assembly precision of each roller, the profiles will bounce up and down, deviate left and right, and slip and move forward and backward during the conveying process, making it difficult for the profiles to move accurately. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a double unidirectional conveying mechanism for photovoltaic frame profiles, which can accurately convey the profiles.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0007] A photovoltaic frame profile duplex unidirectional conveying mechanism includes a support base positioned between a stamping station and a riveting station. The support base has a plurality of roller assemblies for conveying the frame profile, a long conveyor belt, and a short conveyor belt arranged sequentially along the profile conveying direction. The long conveyor belt is mounted on the support base via driven pulleys and driving pulleys at both ends. The short conveyor belt is mounted on the support base via roller assemblies at both ends. A power assembly for driving the roller assemblies, the long conveyor belt, and the short conveyor belt is mounted on the support base. The roller assembly includes a wheel seat mounted on the support base, an axle passing through the wheel seat, a central wheel at one end of the axle, side wheels on both sides of the central wheel, and a synchronous pulley connected to the power assembly at the other end of the axle.

[0008] To further optimize the technical solution, the power assembly includes a drive wheel assembly and a driven wheel assembly respectively disposed at both ends of the support base, and a power motor connected to the drive wheel assembly via a short transmission synchronous belt. A long transmission synchronous belt is disposed between the drive wheel assembly and the driven wheel assembly. A synchronous belt pressing device is disposed on the support base next to the roller assembly and the drive wheel assembly of the conveyor belt for pressing the long transmission synchronous belt onto the synchronous belt pulley of the roller assembly and the drive wheel assembly of the conveyor belt.

[0009] To further optimize the technical solution, the synchronous belt clamping device includes a vertical plate set on a support base, with a shaft mounted on the top of the plate via a nut, and a deep groove ball bearing for clamping the long transmission synchronous belt mounted on the shaft.

[0010] To further optimize the technical solution, the middle wheel and the side wheels are detachably mounted on the axle, and the axle is equipped with adjusting shims for adjusting the distance between the two side wheels by screws.

[0011] To further optimize the technical solution, a support roller is provided between the roller assembly and the long conveyor belt to transfer the frame profile onto the long conveyor belt.

[0012] Due to the adoption of the above technical solutions, the technological progress achieved by this utility model is as follows.

[0013] This utility model provides a photovoltaic frame profile duplex unidirectional conveying mechanism with simple structure and strong practicality. It uses a combination of rollers and conveyor belts to convey the frame profile. During the conveying process, it can effectively avoid the frame profile from shifting and slipping. No displacement occurs during the conveying process, thus realizing the precise conveying and positioning of the frame profile. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] A photovoltaic frame profile duplex unidirectional conveying mechanism, combined with Figures 1 to 3 As shown, the support base 1 is set on the station between the stamping station and the riveting station. Roller assembly 2, long conveyor belt 4 and short conveyor belt 6 are arranged sequentially on the support base 1 along the profile conveying direction. There are several roller assemblies 2, which are used to convey the stamped frame profile. The long conveyor belt 4 is set on the support base 1 through the conveyor belt at both ends from the wheel axle assembly 3 and the conveyor belt drive wheel assembly 5. The short conveyor belt 6 is set on the support base 1 through the roller assemblies at both ends.

[0020] The roller assembly 2 includes a wheel seat 14 mounted on a support base 1, a wheel axle 20 passing through the wheel seat 14, a central wheel 15 mounted on one end of the wheel axle via side wheels 16 on both sides, and a synchronous pulley 17 mounted on the other end of the wheel axle 20. The synchronous pulley 17 is connected to a power assembly to realize the rotation of the central wheel and the side wheels. The front edge frame profile is conveyed through the central wheel of the roller assembly, and the short conveyor belts 6 are all mounted on the central wheel 15.

[0021] Both the middle wheel 15 and the side wheels 16 are detachably mounted on the axle 20. The axle 20 is equipped with an adjusting shim 18 by screws 19, which is used to adjust the distance between the two side wheels 16 to accommodate the conveying of frame profiles of different widths.

[0022] A support roller 12 is provided between the roller assembly 2 and the long conveyor belt 4 to transfer the frame profile conveyed by the roller assembly to the long conveyor belt.

[0023] The support base 1 is equipped with a power component to drive the roller assembly 2, the long conveyor belt 4 and the short conveyor belt 6 to rotate, thereby realizing the conveying of the frame profile.

[0024] The power assembly includes a drive wheel assembly 7, a driven wheel assembly 13, and a power motor 8. The power motor 8 is connected to the drive wheel assembly 7 via a short synchronous belt 9. A long synchronous belt 11 is provided between the drive wheel assembly 7 and the driven wheel assembly 13. A synchronous belt pressing device 10 is provided on the support seat 1 on the side of the roller assembly 2 and the conveyor belt drive wheel assembly 5. This device is used to press the long synchronous belt 11 onto the synchronous belt pulley 17 of the roller assembly and the conveyor belt drive wheel assembly, thereby driving the middle wheel of the roller assembly and the long conveyor belt 4 and the short conveyor belt 6 on the middle wheel to rotate, thus realizing the conveying of the frame profile.

[0025] The timing belt clamping device 10 includes a vertical plate 21 mounted on a support base 1. A shaft 23 is mounted on the top of the vertical plate 21 via a nut 22. A deep groove ball bearing 24 is mounted on the shaft 23 to clamp the long transmission timing belt, so that the long transmission timing belt fits against the timing belt pulley, thereby realizing the rotation of the middle pulley, the long conveyor belt, and the short conveyor belt of the roller assembly.

[0026] In this invention, when conveying the frame profile, the front section is conveyed by multiple roller assemblies, and the spacing is adjusted by the side wheels on both sides to ensure smooth passage of the frame profile. The conveying of the frame profile by the roller assembly facilitates the lateral flipping of the punching and unloading robot at the punching station between the rollers and the opening and clamping actions of the cylinder gripper. During the conveying process, the robot is given room to maneuver.

[0027] When the material is conveyed to the middle section, it is transported by a long conveyor belt. The frame profile and the conveyor are in line-to-surface contact, resulting in a relatively large adhesion friction. During the conveying process, the frame profile will not experience any abnormalities such as shifting or deviating. At the same time, the conveying width of the long conveyor belt can be adjusted according to the width of the frame profile being conveyed.

[0028] When the material is conveyed to the rear section, the corresponding pressing and riveting loading position adopts a combination of short conveyor belts and roller assemblies. The short conveyor belts and rollers can be adjusted according to the width of the frame profile. Space is left between the two short conveyor belts for the pressing and riveting loading robot to move, which facilitates the lateral movement of the pressing and riveting loading robot and the opening and clamping action of the cylinder gripper.
