Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a four-corner pre-cleaning machine for solar components. Background Art

[0002] Solar photovoltaic modules are generally assembled from a large photovoltaic substrate and four frames, which are connected by special glue. In order to ensure that the contact surfaces of the two are completely connected, the amount of glue used will inevitably be slightly excessive. The excess glue will always be squeezed out from the joints after assembly. There is a risk that this part of the glue will stick to the photovoltaic substrate, which will affect the appearance and quality of the solar photovoltaic module.

[0003] Chinese patent CN118142923A discloses a solar panel glue cleaning device, which is also used to clean up the overflow glue. The device uses a feed belt to feed the solar panel, and then uses a straightening device to straighten it. The handling device uses the pearl cotton to be transported from the loading rack to the transfer rack, and then the wiping manipulator takes the pearl cotton for wiping operation, and the used pearl cotton is discarded in the waste recycling box. Here, there is a stable suction nozzle on the transfer rack to absorb the middle of the pearl cotton, and there are constraint plates on both sides of the transfer platform, which will bend the two sides of the pearl cotton into an arc structure. The wiping tool uses the clamping plates moving towards each other on both sides to clamp the side of the pearl cotton on the wiping head, and then wipe it. The risk in this action is that if the stable suction nozzle breaks the vacuum, the pearl cotton cannot be deformed into an arc structure in advance, which will cause the clamping plate to be unable to clamp it on the wiping head. At this time, there is no other means to indicate that the pearl cotton is clamped, so even if the wiping manipulator continues to move, it cannot complete the glue removal.

[0004] Therefore be necessary to improve equipment to solve the above problems. Utility Model Content

[0031] The utility model is further described in detail below in conjunction with specific embodiments.

[0032] Example:

[0033] like Figure 1 As shown, a solar module four-corner pre-cleaning machine 100 of the utility model comprises a frame 1, a silo unit 2, a loading unit 3, a pre-cleaning unit 4, a plate moving unit 5 and a waste recovery box 6. A silo unit 2, a loading unit 3, a pre-cleaning unit 4 and a waste recovery box 6 are respectively provided on both sides of the plate moving unit 5 in the Y direction, the loading unit 3 is located above the silo unit 2, and the loading unit 3, the plate moving unit 5 and the waste recovery box 6 on the same side are arranged around the pre-cleaning unit 4.

[0034] The silo unit 2 is used to store the wiping sheet 300, the plate shifting unit 5 is used to move and position the solar module 200, the loading unit 3 is used to transfer the wiping sheet 300 to the pre-cleaning unit 4, the waste recovery box 6 is used to collect the used wiping sheet 300, and the pre-cleaning unit 4 uses the wiping sheet 300 to wipe the residual glue on the solar module 200 and then throw it into the waste recovery box 6. Because there is a wiping position at each corner of the solar module 200, in order to save cleaning time, there are two sets of parts related to the movement of the wiping sheet 300 (i.e., the silo unit 2, the loading unit 3, the pre-cleaning unit 4 and the waste recovery box 6), and the pre-cleaning unit 4 on each side is used to wipe the wiping positions at the two corners.

[0035] like Figure 1 and Figure 3 As shown, the frame 1 is provided with a bottom plate 11 at the bottom of both sides of the Y direction, and a plurality of linear guide rails 12 extending along the X direction are provided on the bottom plate 11. The X direction and the Y direction are both located in a horizontal plane and are perpendicular to each other.

[0036] like Figure 2As shown, the plate moving unit 5 includes an X-direction conveying line 51 passing through the middle of the frame 1 along the X-direction, a pair of front and rear alignment modules 52 arranged at both ends of the X-direction conveying line 51, and a pair of left and right alignment modules 53 arranged on both sides of the X-direction conveying line 51.

[0037] The X-direction conveyor line 51 is used to convey the solar module 200 to the inside of the rack 1 , and then the solar module 200 is centered by a pair of front and rear alignment modules 52 and a pair of left and right alignment modules 53 , thereby ensuring the position accuracy of the solar module 200 .

[0038] like Figure 1 and Figure 3 As shown, there are multiple silo units 2 and they are arranged on both sides of the shift plate unit 5 in the Y direction. Each silo unit 2 includes a wiping plate 21 sliding along the linear guide rail 12 and a blocking component arranged on the upper surface of the wiping plate 21. The wiping plate 21 is rectangular, and the blocking component includes a wiping plate baffle 22 arranged on the short side of the wiping plate 21 and a plurality of wiping plate positioning columns 23 arranged on the long side of the wiping plate 21.

[0039] The silo unit 2 is used to store the wiping sheets 300 for the feeding unit 3 to take. The wiping sheets 300 are tightly stacked on top of the wiping sheet support plate 21. The enclosure component forms a bin surrounding the wiping sheets 300, which is used to block the periphery of the entire stack of wiping sheets 300 to prevent them from tipping over. The wiping sheet baffle 22 blocks the wide side of the wiping sheet 300, and the wiping sheet positioning column 23 blocks the long side of the wiping sheet 300. The more silo units 2 there are, the more bins there are, and the more wiping sheets 300 can be stored, so that long-term automatic cleaning can be maintained. The linear guide rail 12 makes the silo unit 2 present a drawer-type structure. When replacing the wiping sheet 300, the silo unit 2 can be pulled out of the frame 1, and then pushed back into the frame 1 after the replacement is completed.

[0040] like Figure 3 and Figure 6 As shown, the loading unit 3 includes a transfer component 31 located between the hopper unit 2 and the shift plate unit 5 and a loading gripper 32 located above the transfer component 31. The transfer component 31 is fixed on the frame 1 and has an adsorption table 311 with an adsorption surface facing upward and a wiping sheet sensor 312 located on one side of the adsorption table 311. When the wiping sheet sensor 312 senses that the wiping sheet 300 has arrived at the adsorption table 311, the pre-cleaning unit 4 takes away the wiping sheet 300.

[0041] The loading gripper 32 moves the wiping sheet 300 from the top of the silo unit 2 to the transfer assembly 31 to wait for pre-cleaning. Because the wiping sheet 300 is relatively thin, the wiping sheet 300 needs to be sucked by the adsorption table 311 during the transfer. The start time of the suction of the adsorption table 311 is represented by the signal received by the wiping sheet sensor 312.

[0042] like Figure 4 As shown, the loading gripper 32 includes an X-direction module 321 installed on the Y-direction side of the frame 1, a Y-direction module 322 driven to move in translation by the X-direction module 321, a Z-direction module 323 driven to move in translation by the Y-direction module 322, and a suction cup assembly 324 driven to move up and down by the Z-direction module 323; the suction cup assembly 324 includes a suction cup mounting plate 3241 driven by the Z-direction module 323 and a plurality of suction cups 3242 arranged at the lower part of the suction cup mounting plate 3241, and a lifting guide plate 325 guiding the suction cup mounting plate 3241 to move up and down vertically is arranged on the side of the Z-direction module 323. The Z-direction is a vertical direction.

[0043] The X-axis module 321, the Y-axis module 322 and the Z-axis module 323 enable the suction cup 3242 to move in the XYZ three-coordinate space, and the loading gripper 32 absorbs the wiping sheet 300 by the suction cup 3242 and transfers it to the transfer assembly 31. The lifting guide plate 325 is used to guide the lifting of the suction cup assembly 324, so as to prevent the suction cup 3242 from shaking and causing the wiping sheet 300 to fall.

[0044] like Figure 5 and Figure 6 As shown, the pre-cleaning unit 4 includes a manipulator 41 located on one side of the moving plate unit 5 and a rubber wiping head assembly 42 arranged at the free end of the manipulator 41; the rubber wiping head assembly 42 includes a mounting frame 421 connected to the manipulator 41, a pair of clamping cylinders 422 arranged on both sides of the mounting frame 421, and a pressing cylinder 423 arranged in the middle of the mounting frame 421, each clamping cylinder 422 drives a clamping block 4221 extending out of the lower surface of the mounting frame 421, and the pressing cylinder 423 drives a pressing block 4231 extending out of the lower surface of the mounting frame 421, the extension and retraction direction of the clamping cylinder 422 is parallel to the extension and retraction direction of the pressing cylinder 423, the clamping blocks 4221 cooperate with the mounting frame 421 to clamp the two ends of the wiping sheet 300, and the pressing block 4231 presses down the middle of the wiping sheet 300 to make it tight and form a "J" shape structure.

[0045] The pre-cleaning unit 4 removes the wiping sheet 300 from the transfer assembly 31 and removes glue from the four corners of the solar module 200. The wiping sheet 300 here can be made of sliced ​​pearl cotton, which is a thin sponge structure soft material that can absorb glue. It is a consumable during the cleaning process, and only one sheet is used for each wiping. The glue wiping head assembly 42 can clamp the wiping sheet 300 and transform it into a non-planar structure, so that the gluing position of the solar photovoltaic module can be cleaned.

[0046] The working process of the solar module four-corner pre-cleaning device 100 is as follows:

[0047] S1, the panel moving unit 5 uses the X-axis conveyor line 51 to convey the solar panel 200 to the center of the rack 1, and the front and rear alignment modules 52 are centered from the front and rear directions of the conveying direction, and the left and right alignment modules 53 are centered from the two sides of the conveying direction.

[0048] S2. Manually pull the silo unit 2 along the linear guide rail 12 to the outside of the frame 1. After the wiping sheet 300 is stacked in the silo unit 2, push the silo unit 2 into a fixed position in the frame 1. At this time, the silo unit 2 is within the operating range of the loading unit 3.

[0049] S3. The loading gripper 32 moves to the top of the silo unit 2 through the X-axis module 321, the Y-axis module 322, and the Z-axis module 323. The suction cup assembly 324 adsorbs the wiping sheet 300 in the silo unit 2, and then moves to the middle position of the transfer assembly 31. The adsorption platform 311 adsorbs the wiping sheet 300. The size of the wiping sheet 300 is larger than that of the adsorption platform 311, so the edges of the adsorption platform 311 are exposed on both sides to facilitate the clamping of the material block 4221.

[0050] S4. When the wiping sheet sensor 312 senses that the wiping sheet 300 is in place, the manipulator 41 drives the rubber wiping head assembly 42 to move above the transfer assembly 31, and the clamping cylinder 422 pushes the clamping block 4221 to the adsorption surface below the adsorption platform 311. The wiping sheet 300 is deformed and then rebounds so that both sides are located above the clamping block 4221. Then the clamping cylinder 422 tightens the clamping block 4221 so that the clamping block 4221 clamps the wiping sheet 300. The pressing cylinder 423 pushes the pressing block 4231 to push the middle of the wiping sheet 300 out, so that the wiping sheet 300 is tightened into a "J" shape. The manipulator 41 drives the rubber wiping head assembly 42 to wipe the two right-angled sides and the bottom of the solar panel in turn.

[0051] S5. After wiping is completed, the robot 41 drives the rubber wiping head assembly 42 to move above the waste recovery box 6, the pressing cylinder 423 is retracted and the clamping cylinder 422 is pushed out, and the wiping sheet 300 falls into the waste recovery box 6.

[0052] S6. At the same time as step S5, the front and rear return modules 52 and the left and right return modules 53 return to their positions to release the solar module 200, and the panel moving unit 5 then uses the X-axis conveyor line 51 to send out the solar module 200.

[0053] In this method, the feeding unit 3 separates the stacked wiping sheets 300 and pre-positions them on the transfer assembly 31, and the pre-cleaning unit 4 can clamp the wiping sheets 300 with a simple action to avoid the problem of not being able to clamp them, and then wipe and clean the four corners and edges of the solar module 200, avoiding the risk of residual glue sticking back and ensuring product quality. Two groups of pre-cleaning units 4 can operate on both sides of the solar module 200 at the same time, making the time allocation more reasonable and being able to complete the feeding and pre-cleaning operations more efficiently.

[0054] The above 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, which all belong to the protection scope of the present invention.
