Description

Technical field

[0001] The utility model belongs to the technical field of photovoltaic component production, in particular to a photovoltaic component buffer curing system. [Background Technology]

[0002] At present, the curing method of solar photovoltaic modules is mostly to use curing line equipment for curing and cooling. The curing line as a whole not only takes up a large space, but also consumes a lot of energy, has high equipment configuration requirements, high costs and high maintenance costs. If the production line has a slow production rhythm and the short-term cache volume of photovoltaic modules is small, the use of a curing line will waste resources and it will be difficult to achieve the expected economic benefits and production efficiency. Therefore, it is necessary to design a cache curing system for photovoltaic modules with a small short-term cache volume.

[0003] The buffer curing system requires a buffer material frame and a handling device that transports photovoltaic modules on the conveyor line to the buffer material frame. For example, Chinese patent publication No. CN116573316A discloses a material frame picking and placing system and picking and placing method, which includes a first handling device; a second handling device; and several material frame picking and placing devices, which include, from top to bottom, a first telescopic fork assembly and a second telescopic fork assembly. In this scheme, the first telescopic fork assembly lifts the upper material frame at the target position of the entire material frame to be taken out or to be placed in the target material frame. The second telescopic fork assembly places the target material frame on the conveyor into the target position or places the target material frame on the conveyor after taking it out from the target position, and then drives the first telescopic fork assembly again to put the upper material frame back. Therefore, the first telescopic fork assembly needs to lift the material above the material to be picked up and placed before the second telescopic fork assembly can pick up and place the material. In addition, the height of the materials picked up and placed by the second telescopic fork assembly is consistent. When taking out materials, they can only be started from the bottom in sequence, and when placing materials, they are also stacked from the bottom to the top in sequence. Therefore, there is a certain order when picking and placing, which has low flexibility and is not suitable for caching photovoltaic modules.

[0004] Therefore, it is necessary to provide a photovoltaic module buffer curing system to solve the above technical problems. [Utility Model Content]

[0033] Please refer to Figure 1-Figure 7 The present embodiment is a photovoltaic module cache curing system. The photovoltaic module cache curing system 100 includes a conveying device 1 for conveying photovoltaic modules 200, a correction mechanism 2 arranged on the side of the conveying device 1 and correcting the photovoltaic modules 200, a cache silo 4 for caching the photovoltaic modules 200, and a transport device 3 for transporting the photovoltaic modules between the conveying device 1 and the cache silo 4.

[0034] The conveying device 1 includes a drive shaft 11, a third motor 12 that drives the drive shaft 11 to rotate horizontally, a conveyor belt 13 wound around the drive shaft 11, and a blocking assembly 14 disposed at the front end of the conveyor belt 13 to prevent the photovoltaic modules from continuing to be transported forward. Two conveyor belts 13 are disposed horizontally. The blocking assembly 14 includes a blocking plate that prevents the photovoltaic modules from continuing to be transported forward, and a blocking cylinder that drives the blocking plate to move up and down or rotate. The bottom of the conveying device 1 is provided with a ground spike 15. The height of the conveyor belt 13 can be adjusted by adjusting the height of the ground spike 15. This not only adjusts the level of the conveyor belt 13, but also enables the conveyor belt 13 to accommodate photovoltaic modules at processing stations at different heights, thus providing good versatility and high flexibility.

[0035] The alignment mechanism 2 includes an alignment cylinder 21, a support rod 22 driven by the alignment cylinder 21 for forward and backward movement, and a plurality of alignment wheels 23 mounted on the support plate 22. The alignment mechanism 2 aligns the front and rear sides of the PV module, specifically its two long sides. Therefore, two sets of alignment mechanisms 2 are provided, with the front and rear sets positioned opposite each other along the long sides of the PV module.

[0036] The transport device 3 includes a frame 34, a lifting mechanism 31 arranged on the frame 34, a lifting frame 32 driven by the lifting mechanism 31 to move up and down, and a bidirectional telescopic module 33 arranged on the lifting frame 32 and capable of extending to the left or right to take and place photovoltaic components.

[0037] The lifting mechanism 31 includes a first motor 311 fixed to the bottom of the frame 34, a first rotating shaft 312 driven horizontally by the first motor 311, and a second rotating shaft 313 mounted at the top of the frame 34. The first and second rotating shafts 312, 313 are connected by a plurality of chains 314 for rotational transmission. The chains 314 are equipped with adjustment assemblies 315 for adjusting chain length, and the lifting frame 32 is fixed to the adjustment assemblies 315. A pair of slide rails 341 are vertically mounted on the frame 34, and the lifting frame 32 is slidably mounted on the slide rails 341 via sliders.

[0038] In this embodiment, the bidirectional telescopic module 33 is equipped with two rows of telescopic arms to ensure the stability of the pick-and-place operation. The bidirectional telescopic module 33 includes a base 331, a drive assembly 332 mounted on the base 331, and two movable arms 333 mounted on the base 331, which are driven by the drive assembly 332 and move left and right. Each movable arm 333 is equipped with a telescopic arm 334 that can be extended to the left or right and supports the photovoltaic module.

[0039] The bidirectional telescopic module 33 also includes a first limiting chain 335 that limits the leftward extension of the telescopic arm 334, and a second limiting chain 336 that limits the rightward extension of the telescopic arm 334. The upper and lower surfaces of the rear side of the telescopic arm 333 are both provided with first mounting slots for mounting the first limiting chain 335, and the upper and lower surfaces of the front side of the telescopic arm 333 are both provided with second mounting slots for mounting the second limiting chain 335. Support shafts 3331 are disposed within the first and second mounting slots to tension the first and second limiting chains 335 and 336. One end of the first limiting chain 335 is fixed to the lower left side of the telescopic arm 334, with its middle section extending through the first mounting slot to the lower side of the telescopic arm 333, and the other end is fixed to the left side of the base 331. One end of the second limiting chain 336 is fixed to the lower right side of the telescopic arm 334, with its middle section extending through the second mounting slot to the lower side of the telescopic arm 333, and the other end is fixed to the right side of the base 331.

[0040] In other embodiments, the bidirectional telescopic module 33 is provided with a single-row telescopic arm or multiple-row telescopic arms, which is not limited here and can be set according to actual conditions.

[0041] The process of the bidirectional telescopic module 33 taking and placing the photovoltaic component is as follows: the driving component 333 drives the movable arm 333 to move to the left, the telescopic arm 334 moves to the left on the movable arm 333, and the first limit chain 335 limits the distance that the telescopic arm 334 moves to the left. When it extends to the left the maximum distance, it is the first position. When the telescopic arm 334 is in the first position, the telescopic arm 334, the movable arm 333 and the base 331 are in a step-like shape and are lowered from left to right. The telescopic arm 334 extends into the conveying device 1 to take the photovoltaic component 200; after the telescopic arm 334 takes the photovoltaic component, the driving component 333 drives the movable arm 333 to move to the right, and the telescopic arm 334 retracts. At this time, the telescopic arm 334, the movable arm 333 and the base 331 are in a step-like shape. The telescopic arm 334 is in the second position, stacked up and aligned left and right. When the telescopic arm 334 is in the second position, the lifting mechanism 31 drives the lifting frame 32 to move up and down, corresponding to the different height positions of the buffer silo 4. The driving assembly 333 drives the movable arm 333 to move rightward, and the telescopic arm 334 moves rightward on the movable arm 333. The second limit chain 336 limits the distance the telescopic arm 334 moves to the right. When it extends to the right the maximum distance, it is the third position. When the telescopic arm 334 is in the third position, the telescopic arm 334, the movable arm 333 and the base 331 form a step-like shape and rise from left to right. The telescopic arm 334 extends into the buffer silo 4 and places the photovoltaic module 200 on the buffer silo 4. If it is necessary to quickly remove the photovoltaic modules in the buffer silo 4 and place them on the processing conveyor line, the process is exactly the opposite of the above process, but the specific actions are the same and will not be repeated here.

[0042] The drive assembly 332 includes a second motor 3321, a third rotating shaft 3322 that rotates horizontally around the second motor 3321, and gears disposed at both ends of the third rotating shaft. The lower surface of the movable arm 333 is provided with a rack that meshes with the gears. In this embodiment, the third rotating shaft 3322 is driven by a second motor 3321. The gears at both ends of the rotating shaft 3322 engage with racks on the lower surfaces of the two movable arms 334, thereby driving the two movable arms 334 to move left and right.

[0043] A sensing block 337 is provided on the movable arm 333, and a plurality of sensors 338 for detecting the position of the sensing block 337 are provided on the base 331. There are three sensors 338 provided on the left, middle and right sides, which respectively sense and locate the sensing block 337 when it is in the first position, the second position and the third position.

[0044] In order to ensure the stability of the left and right movement of the telescopic arm 334 and the movable arm 333, mutually cooperating sliding grooves and pulleys are provided on the front and rear side walls of the telescopic arm 334 and the movable arm 333, and mutually cooperating sliding grooves and pulleys are provided on the front and rear side walls of the movable arm 333 and the base 331.

[0045] The cache silo 4 includes a silo body 41 and several layers of support components 42 relatively arranged on the front and rear side walls of the silo body 41 and supporting the photovoltaic components. The support components 42 on the front side wall of the silo body 41 are disconnected from the support components 42 on the rear side wall to form an avoidance gap 44 for the movement of the bidirectional telescopic module 33.

[0046] The silo 41 has a square structure, and rollers 43 are provided at the bottom of the silo 41 to facilitate the movement of the cache silo 4. Several layers of support assemblies 42 are arranged at equal intervals in the height direction, and the front and rear support assemblies 42 of each layer extend relative to the center of the silo 41 and are arranged and located at the same height to support the same photovoltaic module. In this embodiment, the support assembly 42 is a plurality of support rods arranged horizontally, and the lower surface of the photovoltaic module is supported on the plurality of support rods, which can be applied to photovoltaic modules of different widths or lengths. In other embodiments, the support assembly 42 is a support plate or other support structure, which is not limited here and can be set according to the design situation.

[0047] When the transport device 3 transports the photovoltaic components to the buffer silo 4, since the bottom of the silo 41 is provided with rollers 43 that are easy to roll, in order to prevent the buffer silo 4 from rolling and thus affecting the transport device 3 in taking and placing the photovoltaic components, a limiting mechanism 5 is provided on the side of the transport device 3 to limit the buffer silo 4. The limiting mechanism 5 includes a U-shaped frame 51 surrounded by three profiles that guides and limits the buffer silo, and a limit switch 52 provided on the front and rear profiles to detect whether the buffer silo 4 is in place. The front and rear profiles of the U-shaped frame 51 guide and limit the buffer silo 4. The U-shaped frame 51 is pushed from the opening on the right side into the U-shaped frame 51 until the roller 43 is restricted by the profile on the left. At this time, the front and rear side walls of the bottom of the silo 41 contact the limit switch 52, indicating that the buffer silo 4 is in place. The transport device 3 starts to work and transports the photovoltaic components 200 on the conveying device 1 to the buffer silo 4 in turn.

[0048] When a photovoltaic module cache curing system 100 provided by the present invention is used to cache and cure photovoltaic modules: the conveying device 1 is connected to the conveying line on the processing station, and the photovoltaic modules are conveyed to the conveying device 1. The blocking cylinder drives the blocking plate to block the photovoltaic modules, and the alignment cylinder 21 drives the alignment wheel 23 to align the two relatively long sides of the photovoltaic modules. At the same time, the cache bin 4 is pushed from the opening on the right side into the U-shaped frame 51 until the roller 43 is restricted by the profile on the left side. At this time, the front and rear side walls of the bottom of the bin body 41 contact the limit switch 52, indicating that the cache bin 4 After the loader 31 has been loaded, the lifting mechanism 31 drives the lifting frame 32 to move up and down to the same height as the conveyor belt 13. The driving assembly 332 drives the movable arm 333 to move to the left, and drives the telescopic arm 334 to extend to the left to the first position. At this time, the telescopic arm 334 extends into the lower surface of the photovoltaic component 200 on the conveyor device 1. The lifting mechanism 31 drives the lifting frame 32 to move upward, and the telescopic arm 334 lifts the photovoltaic component 200 upward. When the driving assembly 333 drives the movable arm 333 to move to the right, and drives the telescopic arm 334 to retract to the second position, the lifting mechanism 31 drives the lifting frame 32 to move upward, and the telescopic arm 334 lifts the photovoltaic component 200 upward. The lowering mechanism 31 drives the lifting frame 32 to move up and down, corresponding to the support assembly 42 on the cache silo 4 where no photovoltaic modules are placed, the driving assembly 333 drives the moving arm 333 to move to the right, and drives the telescopic arm 334 to extend to the right and is in the third position. At this time, the telescopic arm 334 is located below the support assembly 42, and the lifting mechanism 31 drives the lifting frame 32 to move downward, and the telescopic arm 334 moves upward to place the photovoltaic modules 200 on the support assembly 42. The same steps as above are used to fill the cache silo 4 with photovoltaic modules 200, and complete the loading action before curing. The buffer bin 4 is pushed outward from the opening on the right side of the U-shaped frame 51 and is placed for a period of time for curing. During production on the production line, multiple buffer bins 4 can be set up for rotation to perform curing operations. After curing is completed, the buffer bin 4 can be pushed from the opening on the right side into the U-shaped frame 51, and the telescopic arm 334 extends to the right to take out the photovoltaic components from the buffer bin 4 and then retracts. The lifting mechanism 31 drives the lifting frame 32 to move up and down to the same height as the conveyor belt 13, and the telescopic arm 334 extends to the left to place the photovoltaic components on the conveyor belt 13, completing the unloading action after the photovoltaic components are cured.

[0049] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
