Description

Technical Field

[0001] This invention belongs to the field of electrical component technology, specifically relating to an apparatus specifically suitable for handling semiconductor or solid-state devices during manufacturing or processing, and particularly to a photovoltaic glass layout apparatus and its operating method. Background Technology

[0002] Before lamination, photovoltaic glass requires the glass, encapsulant film, and solar cells to be stacked sequentially. Since the final photovoltaic glass needs to be connected to a junction box to transmit the generated electricity to the equipment, the busbars of the solar cells need to have wiring protrusions to insert into wiring holes in the glass. Because the encapsulant film is located between the solar cells and the glass, through-holes corresponding to the wiring protrusions need to be made in the encapsulant film. However, directly creating through-holes in the encapsulant film through the wiring section can lead to voids near the edge of the encapsulant film during subsequent hot-melt adhesive bonding due to thermal shrinkage.

[0003] Therefore, in order to avoid the technical problem of forming through holes in the adhesive film by directly passing through the wiring part, which would lead to voids in the adhesive film near the edge of the wiring part during subsequent hot melting of the adhesive film, it is necessary to design a photovoltaic glass layout device and its working method.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention

[0005] This disclosure provides at least one photovoltaic glass layout device and its operating method.

[0006] In a first aspect, embodiments of this disclosure provide a photovoltaic glass layout device, comprising:

[0007] Load-bearing mechanism and drilling mechanism;

[0008] The supporting mechanism supports the photovoltaic glass, and its wiring portion faces upward;

[0009] The drilling mechanism is located above the supporting mechanism. After descending and passing through the wiring portion of the photovoltaic glass, the drilling mechanism drills a hole in the encapsulant film of the photovoltaic glass.

[0010] The drilling mechanism includes:

[0011] The outer sleeve is vertically positioned above the supporting mechanism;

[0012] The punching assembly is inserted inside the outer sleeve;

[0013] The coverage area of ​​the perforated component is adapted to the busbar protrusion in the photovoltaic glass;

[0014] After the outer sleeve passes through the wiring section, it presses against the adhesive film. The punching component surrounds the busbar protrusion under the isolation of the adhesive film, and heat-melts the adhesive film to form a through hole that matches the busbar protrusion. Then the punching component expands outward toward the inner wall of the outer sleeve and heat-shrinks the edge of the through hole.

[0015] In one alternative implementation, the punching assembly includes:

[0016] The movable column is slidably disposed inside the outer sleeve;

[0017] An arc-shaped piece is arranged around the movable column, and an elastic ring is fitted on the outer wall of the arc-shaped piece so that the area enclosed by adjacent arc-shaped pieces when the side walls are in close contact can be adapted to the protrusion of the busbar.

[0018] The bottom surface of the arc-shaped piece is a cutting edge, and the lowest point of the cutting edge is flush with the bottom surface of the outer sleeve.

[0019] After the outer sleeve extends into the wiring section, it presses down on the adhesive film. At this time, the area enclosed by the arc-shaped plate will raise and block the busbar, and the blade surface will contact the adhesive film. After the external heat source heats the movable column, the heat is transferred to the arc-shaped plate through the movable column. The adhesive film at the contact position of the blade surface melts and separates from the adhesive film at other positions, forming the through hole.

[0020] In one optional embodiment, an annular groove is formed on the outer wall of the movable column, and the bottom surface of the movable column is higher than the lowest point of the cutting edge.

[0021] A limiting ring is provided on the inner wall of the outer sleeve. The movable column passes through the limiting ring and contacts the inner wall of the limiting ring. The limiting ring is located above the arc-shaped piece, and the top surface of the arc-shaped piece contacts the bottom surface of the limiting ring.

[0022] The top surface of the arc-shaped piece is provided with a protrusion, which slides on the top surface of the annular groove along the radial direction of the outer sleeve.

[0023] The bottom surface of the protrusion is a slope;

[0024] The inner bottom surface of the annular groove is chamfered;

[0025] When adjacent arc-shaped pieces are in close contact with each other on the sidewalls, there is a gap between the outer wall of the arc-shaped piece and the inner wall of the outer sleeve;

[0026] After the through hole is formed, the movable column moves upward, the chamfer approaches and contacts the inclined surface of the protrusion, so that each arc-shaped piece moves along the radial direction of the outer sleeve and approaches the outer sleeve. A gap is gradually formed between adjacent arc-shaped pieces, the space enclosed by the outer sleeve and the adhesive film increases, and a negative pressure is formed to draw the edge of the through hole into the space between the arc-shaped piece and the inner wall of the outer sleeve. The residual heat of the arc-shaped piece causes the adhesive film between the arc-shaped piece and the inner wall of the outer sleeve to shrink thermally.

[0027] In one optional embodiment, the top surface of the outer sleeve is connected to an air source, and the air source is electrically connected to the control module.

[0028] The control module is configured to control the gas source to operate. When the gas source extracts gas from the outer sleeve, the air pressure between the ring and the top surface of the outer sleeve decreases, causing the movable column to move upward.

[0029] In one optional embodiment, the photovoltaic glass includes: a pair of backplates disposed vertically;

[0030] A battery cell is disposed between two back glass panels, and the battery cell is provided with several busbar protrusions;

[0031] An adhesive film is provided between the battery cell and the two back glass panels, and the adhesive film covers the battery cell.

[0032] One of the back panel glass pieces is provided with a wiring portion corresponding to the busbar protrusion. The wiring portion penetrates the back panel glass along the thickness direction of the back panel glass, so that the busbar protrusion is located in the corresponding wiring portion after passing through the hole.

[0033] When the photovoltaic glass is placed on the support structure, the wiring section should face upwards.

[0034] In one alternative embodiment, the carrying mechanism includes: a pair of parallel conveyor belts;

[0035] The punching mechanism is located above the conveyor belt;

[0036] The photovoltaic glass is mounted on two conveyor belts.

[0037] In one optional embodiment, the outer sleeve is disposed on the mounting block, the mounting block is disposed on the three-axis sliding joint, and the three-axis sliding joint is electrically connected to the control module;

[0038] The mounting block is equipped with a camera module, which is electrically connected to the control module. The camera module captures images of the photovoltaic glass to identify the location of the wiring section.

[0039] The control module is configured to control the three-axis moving pair to move the outer sleeve according to the position of the wiring part, so that the punching mechanism is aligned with the wiring part.

[0040] Secondly, embodiments of this disclosure provide a punching mechanism for the above-mentioned photovoltaic glass layout device, comprising:

[0041] The punching mechanism includes: an outer sleeve and a punching assembly;

[0042] The outer sleeve is vertically positioned above the supporting mechanism;

[0043] The perforation assembly is inserted inside the outer sleeve;

[0044] The area enclosed by the perforated component is adapted to the busbar protrusion in the photovoltaic glass;

[0045] The punching assembly includes: a movable column and several arc-shaped pieces;

[0046] The movable column is slidably disposed inside the outer sleeve;

[0047] The arc-shaped plate is arranged around the movable column;

[0048] The outer wall of the arc-shaped piece is fitted with an elastic ring so that the area enclosed by adjacent arc-shaped pieces when the side walls are in close contact can be adapted to the protrusion of the busbar.

[0049] The bottom surface of the arc-shaped piece is a cutting edge, and the lowest point of the cutting edge is flush with the bottom surface of the outer sleeve.

[0050] In one optional embodiment, an annular groove is formed on the outer wall of the movable column, and the bottom surface of the movable column is higher than the lowest point of the cutting edge.

[0051] A limiting ring is provided on the inner wall of the outer sleeve. The movable column passes through the limiting ring and contacts the inner wall of the limiting ring. The limiting ring is located above the arc-shaped piece, and the top surface of the arc-shaped piece contacts the bottom surface of the limiting ring.

[0052] The top surface of the arc-shaped piece is provided with a protrusion, which slides on the top surface of the annular groove along the radial direction of the outer sleeve.

[0053] The bottom surface of the protrusion is a slope;

[0054] The inner bottom surface of the annular groove is chamfered;

[0055] When adjacent arc-shaped pieces are in close contact with each other on the sidewalls, there is a gap between the outer wall of the arc-shaped piece and the inner wall of the outer sleeve.

[0056] Thirdly, embodiments of this disclosure provide a method for operating a typesetting device employing the aforementioned photovoltaic glass, comprising:

[0057] After the outer sleeve passes through the wiring section, it presses against the adhesive film. The punching assembly, isolated by the adhesive film, raises and surrounds the busbar to form the through hole. Then, the punching assembly expands outward toward the inner wall of the outer sleeve and heat-shrinks the edge of the through hole.

[0058] The beneficial effects of this invention are as follows: the photovoltaic glass layout device includes a carrying mechanism and a drilling mechanism; the carrying mechanism carries the photovoltaic glass with the wiring portion on the photovoltaic glass facing upwards; the drilling mechanism is positioned above the carrying mechanism, and after descending and passing through the wiring portion of the photovoltaic glass, it drills a hole in the adhesive film of the photovoltaic glass; wherein, the drilling mechanism includes an outer sleeve and a drilling component; the outer sleeve is vertically positioned above the carrying mechanism; the drilling component passes through the outer sleeve; the area surrounded by the drilling component is adapted to the busbar protrusion in the photovoltaic glass; after the outer sleeve passes through the wiring portion, it presses down on the adhesive film, and the drilling component, under the isolation of the adhesive film, surrounds the busbar protrusion and heat-melts the adhesive film to form a through hole adapted to the busbar protrusion, and then the drilling component expands outwards towards the inner wall of the outer sleeve, heat-shrinking the edge of the through hole, thereby realizing the drilling of the through hole in the adhesive film. After drilling, the edge of the through hole in the adhesive film is heat-shrinked so that no voids will appear at the edge of the through hole due to heat shrinkage during subsequent heat melting of the adhesive film.

[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0075] Before lamination, photovoltaic glass requires the glass, encapsulant film, and solar cells to be stacked in sequence. Since the photovoltaic glass needs to be connected to the junction box after completion to transmit the generated power to the equipment, the busbars of the solar cells need to have wiring protrusions to be inserted into the wiring holes opened in the glass. Since the encapsulant film is located between the solar cells and the glass, through holes corresponding to the wiring protrusions need to be opened in the encapsulant film. The adhesive film has good heat shrinkage properties. To ensure uniform adhesive coverage after subsequent lamination, a redundant adhesive film design is usually adopted, that is, the size of the adhesive film is designed to be slightly larger than the size of the glass. However, the inventors found that this presents a certain difficulty in drilling holes. If the size of the adhesive film hole is the same as the glass hole, the adhesive film may shrink during subsequent lamination, resulting in empty adhesive at the edge of the glass hole. If the size of the adhesive film hole is smaller than the size of the glass hole, when the busbar protrusion of the battery cell is inserted, the bottom edge of the busbar protrusion will contact the adhesive film, which will cause the adhesive liquid to cover or partially adhere to the busbar protrusion after the adhesive film melts. Since the adhesive is insulating, if the busbar protrusion is covered by adhesive, it will lead to a decrease in the quality of subsequent wiring and unstable electrical connection.

[0076] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0077] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0078] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0079] like Figure 1 and Figure 2As shown, at least one disclosed embodiment provides a photovoltaic glass layout device, including: a supporting mechanism 1 and a drilling mechanism 2; the supporting mechanism 1 supports photovoltaic glass 4, with the wiring portion 46 on the photovoltaic glass 4 facing upwards; the drilling mechanism 2 is disposed above the supporting mechanism 1, and the drilling mechanism 2 descends through the wiring portion 46 of the photovoltaic glass 4 to drill holes in the adhesive film 44 of the photovoltaic glass 4; wherein, the drilling mechanism 2 includes: an outer sleeve 21 and a drilling assembly 22; the outer sleeve 21 is vertically disposed above the supporting mechanism 1; the drilling assembly 22 passes through the outer sleeve 21. The area enclosed by the perforation component 22 is adapted to the busbar protrusion 43 in the photovoltaic glass 4. After the outer sleeve 21 passes through the wiring part 46, it presses down on the adhesive film 44. The perforation component 22 surrounds the busbar protrusion 43 under the isolation of the adhesive film 44, and heat-melts the adhesive film 44 to form a through hole 45 adapted to the busbar protrusion 43. Then the perforation component 22 expands outward towards the inner wall of the outer sleeve 21 and heat-shrinks the edge of the through hole 45, thereby realizing the perforation on the adhesive film 44. After the perforation, the edge of the through hole 45 on the adhesive film 44 is heat-shrinked so that no empty adhesive will appear at the edge of the through hole 45 due to heat shrinkage when the adhesive film 44 is subsequently heat-melted.

[0080] In this embodiment, the size of the outer sleeve 21 is smaller than the size of the wiring portion 46, so that the outer sleeve 21 can extend into the wiring portion 46.

[0081] In this embodiment, the size of the punching mechanism 2 is adapted to the size of the busbar protrusion 43 to ensure that the through hole 45 finally formed on the adhesive film 44 can satisfy the passage of the busbar protrusion 43, and that no melted adhesive film 44 will adhere to the busbar protrusion 43 when the adhesive film 44 melts subsequently.

[0082] In this embodiment, before punching holes in the adhesive film 44, the adhesive film 44 is directly and completely covered on the battery cell 42.

[0083] like Figure 2 , Figure 3 and Figure 4As shown, in one optional embodiment, the punching assembly 22 includes: a movable column 221 and a plurality of arc-shaped pieces 222; the movable column 221 is slidably disposed within the outer sleeve 21; the arc-shaped pieces 222 are disposed around the movable column 221; an elastic ring 223 is sleeved on the outer wall of the arc-shaped pieces 222 so that the area enclosed by adjacent arc-shaped pieces 222 when the side walls are in close contact adapts to the busbar protrusion 43; the bottom surface of the arc-shaped pieces 222 is a cutting edge 226. The lowest point of the cutting edge 226 is flush with the bottom surface of the outer sleeve 21. After the outer sleeve 21 extends into the wiring part 46, it presses down on the adhesive film 44. At this time, the area enclosed by the arc-shaped piece 222 surrounds the busbar protrusion 43, and the cutting edge 226 contacts the adhesive film 44. Heat is transferred to the arc-shaped piece 222 through the movable column 221. The adhesive film 44 at the contact position of the cutting edge 226 melts and separates from the adhesive film 44 at other positions. A through hole 45 that matches the busbar protrusion 43 is formed by thermal melting on the adhesive film 44.

[0084] In this embodiment, when drilling, the cutting edge 226 contacts the adhesive film 44 and melts the adhesive film 44 at the position where the cutting edge 226 contacts the adhesive film 44. At this time, the cutting edge 226 can ensure that the adhesive film 44 in the area enclosed by the elastic ring 223 melts and separates from other parts of the adhesive film 44.

[0085] like Figure 2 As shown, in one optional embodiment, an annular groove 224 is formed on the outer wall of the movable column 221, and the bottom surface of the movable column 221 is higher than the lowest point of the cutting surface 226; a limiting ring 211 is provided on the inner wall of the outer sleeve 21, the movable column 221 passes through the limiting ring 211 and contacts the inner wall of the limiting ring 211, the limiting ring 211 is above the arc-shaped piece 222, and the top surface of the arc-shaped piece 222 contacts the bottom surface of the limiting ring 211; a protrusion 225 is provided on the top surface of the arc-shaped piece 222, and the protrusion 225 slides on the top surface of the annular groove 224 along the radial direction of the outer sleeve 21; the bottom surface of the protrusion 225 is an inclined surface 227; the inner bottom surface of the annular groove 224 is provided with a chamfer 228; adjacent arcs When the curved piece 222 is in close contact with the side wall, there is a gap between the outer wall of the curved piece 222 and the inner wall of the outer sleeve 21. After the through hole 45 is formed on the adhesive film 44, the movable column 221 moves upward, and the chamfer 228 approaches and contacts the inclined surface 227 of the protrusion 225, so that each curved piece 222 moves in the radial direction of the outer sleeve 21 and approaches the outer sleeve 21. A gap is gradually formed between adjacent curved pieces 222, the space enclosed by the outer sleeve 21 and the adhesive film 44 increases, the air pressure decreases, and the gas flows towards the bottom surface of the movable column 221, drawing the edge of the through hole 45 on the adhesive film 44 into the space between the curved piece 222 and the inner wall of the outer sleeve 21. The residual heat of the curved piece 222 causes the adhesive film 44 between the curved piece 222 and the inner wall of the outer sleeve 21 to shrink.

[0086] In this embodiment, when the arc-shaped piece 222 is clamped by the elastic ring 223 so that the sidewalls of adjacent arc-shaped pieces 222 come into contact, the protrusion 225 comes into contact with the inner sidewall of the annular groove 224. At this time, the lowest point of the cutting edge 226 is parallel to the bottom surface of the outer sleeve 21. The elastic ring 223 makes the arc-shaped piece 222 hug the movable column 221, preventing the arc-shaped piece 222 from moving.

[0087] In this embodiment, when the movable column 221 moves upward, the arc-shaped piece 222 will not move upward with the movable column 221 due to the obstruction of the limiting ring 211.

[0088] In this embodiment, when the movable column 221 moves upward, the detached adhesive film 44 will be sucked into the area surrounded by the arc-shaped piece 222, ensuring that the part of the adhesive film 44 is separated from the busbar protrusion 43, and avoiding the detached adhesive film 44 remaining on the busbar protrusion 43.

[0089] In this embodiment, as the arc-shaped piece 222 moves radially toward the outer sleeve 21, the cutting edge 226 pushes the adhesive film 44 corresponding to the edge of the through hole 45 toward the outer sleeve 21. When a gap appears between the arc-shaped pieces 222, the gas between the outer wall of the arc-shaped piece 222 and the inner wall of the outer sleeve 21 flows to the area between the arc-shaped pieces 222. Part of the adhesive film 44 at the edge of the through hole 45 is sucked into the space between the arc-shaped piece 222 and the inner wall of the outer sleeve 21. At this time, the residual heat on the arc-shaped piece 222 causes this part of the adhesive film 44 to shrink thermally. After the outer sleeve 21 moves out of the wiring part 46, the thermally shrunken adhesive film 44 is in the wiring part 46. This ensures that when the adhesive film 44 shrinks during subsequent lamination, the adhesive film 44 at the edge of the through hole 45 is in the wiring part 46, allowing the adhesive film 44 to completely cover the edge of the wiring part 46 near the battery cell 42, thus avoiding the presence of empty adhesive.

[0090] In this embodiment, after the outer sleeve 21 is removed from the wiring part 46, air can be supplied to the inner sleeve 21 through the air source 32, so that the movable column 221 moves downward and resets. At this time, the elastic ring 223 resets each arc-shaped piece 222, and the side walls of adjacent arc-shaped pieces 222 come into contact.

[0091] In this embodiment, the heat transfer efficiency of the outer sleeve 21 is less than that of the arc-shaped sheet 222, so that the adhesive film 44 in contact with the outer sleeve 21 will not melt when the arc-shaped sheet 222 melts the adhesive film 44 to make holes.

[0092] In this embodiment, the elastic ring 223 is made of an elastic material so that it deforms when the arc-shaped piece 222 approaches the outer sleeve 21, thus bringing the arc-shaped piece 222 closer to the outer sleeve 21.

[0093] In this embodiment, when the arc-shaped piece 222 moves to the closest distance to the inner wall of the outer sleeve 21, there is still a gap between the arc-shaped piece 222 and the inner wall of the outer sleeve 21, so as to avoid clamping the adhesive film 44 which is between the arc-shaped piece 222 and the inner wall of the outer sleeve 21, and to avoid preventing the adhesive film 44 from shrinking due to heat.

[0094] In this embodiment, after the drilling is completed, the external heat source stops heating the movable column 221, causing the temperature of the arc-shaped piece 222 to drop below the temperature at which the adhesive film 44 melts. When the arc-shaped piece 222 subsequently contacts the adhesive film 44 at the edge of the through hole 45, only the corresponding part of the adhesive film 44 will shrink due to heat and will not melt.

[0095] In this embodiment, an external heat source can heat the gas, and then the heated gas is introduced into the outer sleeve 21 through the gas source 32 to heat the movable column 221. The movable column 221 transfers heat to the arc-shaped plate 222, and the arc-shaped plate 222 melts the adhesive film 44 to make holes.

[0096] In one optional embodiment, the top surface of the outer sleeve 21 is connected to an air source 32, which is electrically connected to a control module. The control module is configured to control the air source 32 to operate. When the air source 32 extracts gas from the outer sleeve 21, the air pressure between the ring and the top surface of the outer sleeve 21 decreases, causing the movable column 221 to move upward.

[0097] In one optional embodiment, the photovoltaic glass 4 includes: a pair of backplates 41 arranged vertically; a solar cell 42 is disposed between the two backplates 41, and the solar cell 42 is provided with a plurality of busbar protrusions 43; an adhesive film 44 is disposed between the solar cell 42 and the two backplates 41, and the adhesive film 44 covers the solar cell 42; one of the backplates 41 is provided with a wiring portion 46 corresponding to the busbar protrusions 43, the wiring portion 46 penetrates the backplate 41 along the thickness direction of the backplate 41, so that the busbar protrusions 43 pass through the hole and are located in the corresponding wiring portion 46; when the photovoltaic glass 4 is placed on the support mechanism 1, the wiring portion 46 is arranged facing upward.

[0098] In one optional embodiment, the supporting mechanism 1 includes: a pair of parallel conveyor belts 11; the punching mechanism 2 is disposed above the conveyor belts 11; and the photovoltaic glass 4 is mounted on the two conveyor belts 11.

[0099] In this embodiment, the conveyor belt 11 can continuously move the photovoltaic glass 4 to below the drilling mechanism 2 for drilling.

[0100] In this embodiment, the state diagram during drilling is as follows: Figure 5 and Figure 6 As shown, the moving direction of the movable column 221 during drilling is as follows: Figure 5As shown in F1, the moving direction of the arc-shaped piece 222 is as follows: Figure 5 As shown in F2.

[0101] In one optional embodiment, the outer sleeve 21 is mounted on the mounting block 31, which is mounted on the three-axis sliding joint 3, which is electrically connected to the control module. The mounting block 31 is equipped with an imaging module, which is electrically connected to the control module. The imaging module captures images of the photovoltaic glass 4 to identify the position of the wiring portion 46. The control module is configured to control the three-axis sliding joint 3 to move the outer sleeve 21 according to the position of the wiring portion 46, so that the drilling mechanism 2 aligns with the wiring portion 46.

[0102] In this embodiment, the three-axis moving pair 3 can drive the outer sleeve 21 to move and align with the wiring part 46, and drive the outer sleeve 21 to descend to punch holes in the adhesive film 44 in the wiring part 46.

[0103] In this embodiment, when the outer sleeve 21 and the like are reset, the adhesive film 44 adsorbed between the arc-shaped pieces 222 can fall off, making it easier to drill holes next time.

[0104] In this embodiment, the air source 32 can be connected to the outer sleeve 21 via a hose or the like.
