Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic manufacturing, in particular to a scooping device for high-temperature adhesive parts of photovoltaic laminates. Background Art

[0002] Before the lamination operation in photovoltaic manufacturing, an adhesive needs to be set on the surface of the packaging material layer to prevent the colloid from overflowing during the lamination process. Generally, when the solar panel is single-glass, the adhesive is made of high-temperature tape; when the solar panel is double-glass, the adhesive is made of high-temperature tape.

[0003] However, during the subsequent junction box installation process, the adhesive needs to be removed from the surface of the photovoltaic laminate and the busbar at the adhesive position is rotated to a position roughly vertical to the surface of the photovoltaic laminate, wherein the busbar is always attached to the surface of the adhesive on the surface of the photovoltaic laminate.

[0004] Existing mechanical devices for removing adhesives from the surface of laminates have at least the following deficiencies when removing adhesives:

[0005] 1. The curing of the colloid makes the adhesive (high-temperature adhesive tape or high-temperature adhesive tape) and the laminate firmly bonded and difficult to tear off, and the colloid will leak out from the busbar holes on the photovoltaic laminate, so that the colloid wraps the root of the busbar, making it difficult to shovel the busbar;

[0006] 2. After tearing off the adhesive, in the subsequent process of removing the adhesive, the two welding joints of the busbar may be bent excessively due to the removal action, which is not conducive to the subsequent straightening operation of the busbar.

[0007] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in the present invention. Summary of the invention

[0008] The utility model aims to provide a scooping device for high-temperature adhesive parts of photovoltaic laminates.

[0009] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a scooping device for high-temperature adhesives of photovoltaic laminates, which is arranged corresponding to a peeling station, and the photovoltaic laminates of the adhesives to be peeled are located in the peeling station; comprising: a pressing part, including a pressing block, which is arranged corresponding to the upper part of the peeling station and is driven to move up and down along the Z axis; and in the first descending state, the bottom end of the pressing block is pressed against the upper part of the adhesive in the peeling station; a heating mechanism is arranged corresponding to the peeling station, which is used to heat the colloid between the bus bar and the adhesive at the peeling station; and a scooping module, including a group of shovel parts arranged relatively in the horizontal direction; the scooping module is driven to move relative to the peeling station in the Z axis, and when the scooping module is in the second descending state, the scooping parts are arranged in pairs on both sides of the adhesive in the peeling station; the scooping module is driven to open and close at the peeling station, and when the scooping module is closed, the adhesive in the peeling station is scooped from the photovoltaic laminate.

During lamination, in order to prevent the colloid from overflowing from the bus bar outlet hole due to being squeezed, a high-temperature adhesive is generally used to seal the bus bar outlet hole. Of course, the high-temperature adhesive is also provided with a hole for the bus bar to pass through. Then, the lamination operation is performed. During lamination, the colloid will adhere to the bus bar near the bus bar outlet hole, that is, after lamination, the root of the bus bar is adhered to the high-temperature adhesive, and there is also some overflowed colloid between the bus bar and the high-temperature adhesive.

[0014] A further technical solution also includes a first driving unit, which is driven and connected to the scooping module and drives the scooping module to move in the Z axis; the first driving unit is also driven and connected to a driving plate, the upper surface of which supports the pressing part and drives the pressing block to move in the Z axis.

[0016] In the above technical solution, the bearing refers to carrying and supporting, that is, when the driving plate drives the pressing part to move along the Z axis, the driving plate contacts the back side of the first fixing plate and bears the weight of the pressing part.

[0017] In the above technical solution, the spacing space refers to the space between the two relatively stationary fixing plates when the first fixing plate and the second fixing plate are relatively stationary.

[0024] According to a further technical solution, the upper surface of each shovel portion is an inclined surface, which converges with the bottom surface of the shovel portion to form an active edge at the convergence point, and the active edge is arranged corresponding to the stripping station.

[0025] The working principle and advantages of this utility model are as follows:

[0026] 1. When the two shovel parts perform the scooping action of approaching each other on the adhesive, the pressing block is pressed down to the peeling station, which can prevent the welding end of the bus bar attached to the surface of the adhesive from being excessively bent when the adhesive is subsequently peeled off;

[0027] 2.

In this case, they are only used to illustrate the positional relationship between the various structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0047] See attached Figure 1 ~Attached Figure 2As shown, the present embodiment provides a scooping device for high-temperature adhesives of photovoltaic laminates, the scooping device is arranged corresponding to a peeling station, the photovoltaic laminate of the adhesive to be peeled off is located in the peeling station, comprising a pressing part 1, a heating mechanism 2 and a scooping module 3, the pressing part 1 comprises a pressing block 11, the pressing block 11 is arranged corresponding to the upper part of the peeling station, and is driven to move up and down along the Z axis, and in the first descending state, the bottom end of the pressing block 11 is pressed against the upper part of the adhesive in the peeling station; the heating mechanism 2 is arranged corresponding to the peeling station, and is used to heat the adhesive in the peeling station; the scooping module 3 comprises a group of scooping parts 31 arranged opposite to each other in the horizontal direction; the scooping module 3 is driven to move the peeling station in the Z axis, and when the scooping module 3 is in the second descending state, the scooping parts 31 are arranged in pairs on both sides of the adhesive in the peeling station, the scooping module 3 is driven to open and close at the peeling station, and when the scooping module 3 is closed, the adhesive in the peeling station is scooped off from the surface of the photovoltaic laminate.

[0048] The purpose of this embodiment is to scoop up the adhesive at the busbar on the laminated photovoltaic laminate, so that the subsequent tearing device can tear off the adhesive, and scoop up the busbar above the adhesive and straighten the position of the busbar, so that the busbar is rotated to a position roughly vertical to the surface of the photovoltaic laminate. When the two shovels 31 perform the scooping action of approaching each other on the adhesive, the pressing block 11 is pressed down to the peeling station, which can prevent the welding end of the busbar attached to the surface of the adhesive from being excessively bent during the subsequent peeling of the adhesive; and the heating mechanism 2 transmits heat to the colloid at the adhesive position, so that the colloid between the busbar and the adhesive at the peeling station melts, and reduces the force required to straighten the busbar.

[0049] The above-mentioned stripping station refers to the position on the surface of the photovoltaic laminate where the adhesive to be stripped exists. It can be understood that the position of the stripping station can be one or more.

[0050] The first descending state is when the pressing part 1 descends to contact the adhesive in the stripping station; the second descending state is when the scooping module 3 descends to contact the surface of the photovoltaic laminate, specifically the surface of the photovoltaic laminate on both sides of the adhesive.

[0051] The shovel parts 31 arranged in pairs move toward each other to achieve a closed state of the scooping module 3 , and the shovel parts 31 arranged in pairs move away from each other to achieve an open state of the scooping module 3 .

[0052] Optionally, a group of relatively arranged shovel parts 31 may include one or more pairs of shovel parts 31, and when the scooping module 3 is in the second descending state, one or more pairs of shovel parts 31 are located on both sides of the adhesive member. In this embodiment, the scooping module 3 includes a pair of shovel parts 31.

[0053] In this embodiment, the shovel portion 31 descends to a position lower than or flush with the two ends of the high-temperature adhesive, and performs a scooping action close to each other once or multiple times along the length direction or width direction of the busbar, and makes the adhesive gradually separate from the surface of the photovoltaic laminate. While the shovel portion 31 is performing the scooping action, the pressing block 11 is pressed down between the two busbars to prevent the adhesive from excessively bending the two welding ends of the busbar during subsequent peeling, which is not conducive to the subsequent straightening operation of the busbar.

[0054] Specifically, the upper surface of the shovel portion 31 is a slope 311, which converges with the bottom surface of the shovel portion 31 to form an active edge 312 at the convergence point. The active edge 312 is arranged corresponding to the peeling station. When performing the scooping action, the active edge 312 extends between the photovoltaic laminate and the adhesive, and the paired active edges 312 are driven close to each other to shovel the adhesive off the surface of the photovoltaic laminate; the slope 311 uses its slope angle to drive the bus bar away from the surface of the photovoltaic laminate during the shoveling process.

[0055] In this embodiment, the heating mechanism 2 is connected to the top of the pressing block 11, and the pressing block 11 can transfer heat to the colloid at the adhesive to be torn off through the heating mechanism 2, so that the colloid of the adhesive melts, reducing the resistance of the two shovel parts 31 to shovel the adhesive, and melt the colloid at the bus bar to reduce the force required for straightening the bus bar. Moreover, while the shovel part 31 is shoveling, it can also drive the bus bar away from the surface of the photovoltaic laminate, which is beneficial to the subsequent straightening operation of the bus bar.

[0056] In this embodiment, the heating mechanism 2 is a hot air cylinder, and the pressing block 11 has a ventilation hole 111 along the Z-axis direction and penetrating the pressing block 11. The air inlet end of the ventilation hole 111 is connected to the hot air cylinder, and the air outlet end of the ventilation hole 111 faces the adhesive in the peeling station, and the air outlet end has a flat pressing surface 112 and two oblique cut surfaces 113 located on both sides of the flat pressing surface 112, such as Figure 4 As shown, the flat pressing surface 112 of the pressing block 11 is pressed down onto the adhesive member in the stripping station, and hot air is transported to the adhesive member through the two oblique cut surfaces 113 to melt the colloid of the adhesive member, making it easier to scoop up and tear off.

[0057] In this embodiment, the second driving part 5 is used to drive the two shovel parts 3111 to move relative to each other along a translation direction, that is, to move closer to each other or farther away from each other, and the translation direction is parallel to the plane where the adhesive member is located.

[0058] This embodiment further includes a first driving part 4 and a second driving part 5 , wherein the first driving part 4 is used to drive the pressing part 1 and the scooping module 3 to perform lifting movements, and the second driving part 5 is used to drive the scooping part 31 to perform opening and closing movements.

[0059] Specifically, the first driving part 4 drives the scooping module 3 and drives the scooping module 3 to move in the Z axis. The first driving part 4 also drives a driving plate 6, the upper surface of which supports the pressing part 1 and drives the pressing block 11 to move in the Z axis.

[0060] Please see Figure 3 The pressing part 1 also includes a first fixed plate 12 and a second fixed plate 13 fixedly arranged on the scooping device. The first fixed plate 12 is stationary relative to the pressing block 11, and the second fixed plate 13 moves relative to the pressing block 11. The first fixed plate 12 and the second fixed plate 13 are arranged in sequence from top to bottom along the Z axis, and both fixed plates are located above the pressing block 11; the driving plate 6 contacts the back side of the first fixed plate 12 to receive the pressing part 1, and drives the pressing block 11 to move along the Z axis relative to the second fixed plate 13; when the pressing part 1 is in the first descending state, the first driving part 4 stops working, or the first driving part 4 drives the scooping module 3 to descend along the Z axis, and at the same time, the driving plate 6 moves in the interval space 14 between the first fixed plate 12 and the second fixed plate 13.

[0061] The “undertaking” refers to bearing and supporting, that is, when the driving plate 6 drives the pressing part 1 to move along the Z axis, the driving plate 6 contacts the back surface of the first fixing plate 12 and bears the weight of the pressing part 1 .

[0062] The spacing space 14 refers to the space between the two relatively stationary fixing plates when the first fixing plate 12 and the second fixing plate 13 are relatively stationary. It can be understood that the distance of the spacing space 14 is variable.

[0063] Furthermore, it also includes an installation bracket 8, and the second fixed plate 13 is fixedly connected to the installation bracket 8. When the driving part and the second driving part 5 are working, the second fixed plate 13 always remains stationary; the second fixed plate 13 has a through hole, the pressing part 1 is penetrated through the through hole, and is driven by the first driving part 4 to move along the Z axis; the heating mechanism 2 is penetrated through the through hole on the second fixed plate 13.

[0064] In some application scenarios, due to the inconsistent heights of the bus bars and adhesives on the surface of the laminate, the shovel portion 31 may contact the laminate before the press block 11, or the press block 11 may contact the laminate before the shovel portion 31. At this time, it is also necessary to consider that when the first drive unit 4 continues to drive the press block 11 to descend or continues to drive the shovel portion 31 to descend, the shovel portion 31 or the press block 11 that has contacted the surface of the laminate will not continue to be pressed down and cause damage to the surface of the laminate.

[0065] If the pressing block 11 reaches the first descending state and the shovel part 31 also reaches the second descending state, the first driving part 4 stops working, and the shovel part 31 is driven by the second driving part 5 to open and close; if the pressing block 11 reaches the first descending state and the shovel part 31 has not reached the second descending state, the first driving part 4 continues to work, driving the driving plate 6 to descend and detach from the back of the first fixed plate 12. At this time, since the bottom end of the pressing block 11 contacts the adhesive member and the first fixed plate 12 and the pressing block 11 are relatively stationary, the first fixed plate 12 and the second fixed plate 13 are both stationary, and there is a spacing space 14 between the two relatively stationary fixed plates. After the driving plate 6 detaches from the back of the first fixed plate 12, it moves in the spacing space 14. Therefore, the first driving part 4 will not drive the pressing block 11 to move at this time, but only drives the scooping module 3 to move, so as to prevent the pressing block 11 from continuing to descend and causing damage to the structure of the photovoltaic laminate.

[0066] In this embodiment, the second driving part 5 includes a guide rail 51 and two translation parts 52 slidably disposed on the guide rail 51 . Each translation part 52 is fixedly connected to a shovel part 31 . The two shovel parts 31 move relatively along the guide rail 51 driven by the translation part 52 .

[0067] If the shovel part 31 reaches the second descending state and the pressure block 11 has not reached the first descending state, the first driving part 4 needs to continue to drive the pressure block 11 to descend to the middle area where it contacts the two bus bars. Since the first driving part 4 and the second driving part 5 are drivingly connected, when the first driving part 4 works to drive the pressure block 11 to descend, it will inevitably cause the second driving part 5 and the two shovel parts 31 located on the second driving part 5 to descend. In order to avoid the two shovel parts 31 continuing to descend and causing structural damage to the bus bar or laminate, in this embodiment, a first elastic member 7 is provided between each translation part and the corresponding shovel part 31. When the first driving part 4 drives the second driving part 5 to descend, the driving force of the translation part on the shovel part 31 will be converted into the compression potential energy of the first elastic member 7. At this time, it can be understood that the first driving part 4 only drives the pressure block 11 to descend, which can also prevent the shovel part 31 from continuing to descend and causing damage to the bus bar or the surface of the laminate.

[0068] Optionally, the first elastic member 7 is a spring.

[0069] Optionally, the first driving part 4 and the second driving part 5 both include driving cylinders.

[0070] It can be understood that the spacing space 14 has a sufficient movement distance so that the driving plate 6 will not contact the second fixing plate 13 during the entire movement process.

[0071] In this embodiment, two adjusting columns 15 are further included. The two adjusting columns 15 are slidably connected to the through holes of the second fixed plate 13 along the Z-axis direction. The two adjusting columns 15 are respectively located on both sides of the hot air cylinder, and the bottom ends of the two adjusting columns 15 are connected to a third fixed plate 16. The third fixed plate 16 is also fixedly connected to the hot air cylinder. When the hot air cylinder is driven to move up and down, the two adjusting columns 15 and the third fixed plate 16 can better maintain the stability of the hot air cylinder during the lifting process.

[0072] Furthermore, two second elastic members (not shown in the figure) are sleeved on the two adjustment columns 15 between the second fixing plate 13 and the third fixing plate 16, so that the pressing block 11 has sufficient stability when pressed down to the stripping station.

[0073] Optionally, the second elastic member is a spring.

[0074] The working process of the existing utility model is as follows:

[0075] The first driving part 4 drives the pressing block 11 and the two shovel parts 31 to descend simultaneously;

[0076] When the two shovel parts 31 preferentially reach the second descending state, the first driving part 4 continues to descend to drive the pressing block 11 to descend, thereby driving the second driving part 5 fixedly connected to the first driving part 4 to continue to descend. The second driving part 5 includes two translation parts, each of which is fixedly connected to a shovel part 31, and a first elastic member 7 is arranged between each translation part and the corresponding shovel part 31. When the first driving part 4 continues to descend, the driving force of the translation part on the shovel part 31 will be converted into the compression potential energy of the first elastic member 7. At this time, it can be understood that the first driving part 4 only drives the pressing block 11 to descend, and it can also prevent the shovel part 31 from continuing to descend and causing damage to the busbar or the surface of the laminate;

[0077] When the pressing block 11 reaches the first descending state first, the surface of the photovoltaic laminate provides support force for the pressing block 11, and the first driving unit 4 continues to drive the two shovel parts 31 to descend, thereby driving the driving plate 6 fixedly connected to the first driving unit 4 to descend and break away from the back of the first fixed plate 12, and move in the interval space 14 between the relatively static first fixed plate 12 and the second fixed plate 13, without providing driving action to the first fixed plate 12 and the pressing block 11. At this time, it can be understood that the first driving unit 4 only drives the shovel part 31 to descend, thus preventing the pressing block 11 from continuing to descend and causing damage to the busbar or the surface of the laminate;

[0078] When the two shovel parts 31 and the pressing block 11 are both located on the surface of the photovoltaic laminate, the pressing block 11 has a ventilation hole 111, the air inlet end of the ventilation hole 111 is connected to the hot air cylinder, and the air outlet end is directly facing the adhesive in the stripping station. The hot air cylinder delivers the generated hot air to the colloid at the adhesive to melt the colloid at the adhesive, making it easier for the shovel part 31 to scoop up the adhesive, and melt the colloid at the root of the busbar, so as to reduce the force required for straightening the busbar;

[0079] The two shovel parts 31 are driven by the second driving part 5 to perform an opening and closing action, and the action edges 312 of the two shovel parts 31 are driven by the second driving part 5 to perform a closing action between the photovoltaic laminate and the adhesive, so that the adhesive is separated from the photovoltaic laminate after shoveling. While the two shovel parts 31 are performing a shoveling action, the inclined surface 311 uses its inclined surface angle to drive the bus bar away from the surface of the photovoltaic laminate during the shoveling process, which is beneficial to the subsequent straightening operation of the bus bar;

[0080] Thus, the purpose of scooping up the adhesive member and correcting the direction of the busbar so that the busbar and the surface of the photovoltaic laminate are substantially vertical is achieved.

[0081] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
