Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing equipment technology, and in particular to a photovoltaic module manufacturing equipment. Background Technology

[0002] A photovoltaic (PV) module is a unit consisting of multiple solar cells arranged in a specific array and connected in series or parallel to form a complete unit with a specific output power. The manufacturing process of a PV module mainly involves texturing, diffusion, etching, and coating silicon wafers to form solar cells, and then using welding and encapsulation processes to electrically connect and physically protect the cells.

[0003] In recent years, with the accelerated transformation of the photovoltaic industry from P-type to N-type technology, new process routes such as TOPCon, HJT, and XBC have flourished. Among them, XBC (interdigitated back contact cell) technology has become the mainstream process for photovoltaic modules due to its advantages such as unobstructed front of the module, no need for silver paste printing, high photoelectric conversion efficiency, and beautiful appearance.

[0004] Currently, XBC modules are still primarily welded using traditional thermal infrared welding technology. While the basic principle is similar to conventional SMBB welding, the fact that all the grid lines of XBC cells are designed on the back side and arranged in an interdigitated pattern makes them more prone to various manufacturing defects during the cutting, positioning, and handling of the solder strip. Specifically, when traditional pressing fixtures press the solder strip and cells, stress concentration can easily lead to cell breakage, resulting in a significantly higher risk of breakage than conventional products and a lower overall yield rate for photovoltaic modules.

[0090] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0091] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0092] This utility model discloses a photovoltaic module manufacturing equipment, as shown in the attached figure. Figures 1 to 4 As shown, it includes a conveying mechanism 1 and an adsorption mechanism 2. The transmission mechanism includes a conveyor belt 11, a driving pulley, a driven pulley, and a transmission motor. The transmission motor is connected to the driving pulley. The conveyor belt 11 passes around the driving pulley and the driven pulley, so that the driving pulley drives the conveyor belt 11 to move, thereby conveying the composite film 01.

[0093] As attached Figure 4 As shown, the conveyor belt 11 has several sets of adsorption holes 111, with each set of adsorption holes 111 evenly spaced. Specifically, each adsorption hole 111 is an elliptical hole penetrating along the thickness direction of the conveyor belt 11. Considering that the photovoltaic module's cell grid lines adopt an interdigitated arrangement structure, the composite film 01 has several sets of insulating holes 011, with each set of insulating holes 011 evenly spaced. The insulating holes 011 are used to prevent the exposed solder ribbons 03 from contacting adjacent cells 02 during the module lamination process, avoiding short circuits caused by electrical connections and ensuring the reliability and safety of the photovoltaic module. All adsorption holes 111 and all insulating holes 011 are linearly distributed along the length direction of the conveyor belt 11. The distance between two adjacent sets of insulating holes 011 is an integer multiple of the distance between two adjacent sets of adsorption holes 111, ensuring that the insulating holes 011 are aligned with the adsorption holes 111 on the thickness of the composite film 01.

[0094] The adsorption mechanism 2 includes an adsorption base plate 21, a vacuum pump, and a vacuum tube connecting the adsorption base plate 21 and the vacuum pump. The adsorption base plate 21 is located below the conveyor belt 11 and has a vacuum section. The vacuum pump provides negative pressure to the vacuum section through the vacuum tube. The vacuum section is preferably a groove structure provided in the adsorption base plate 21. Of course, it can also be a through-hole structure provided in the adsorption base plate 21, which is not specifically limited here.

[0095] It is particularly important to note that, in terms of the thickness of the composite film 01, the vacuum section, the adsorption hole 111, and the insulating hole 011 are arranged sequentially from bottom to top, meaning that the three are interconnected along the thickness direction of the composite film 01. (See attached image.) Figure 5 As shown, the vacuum section first generates negative pressure adsorption force through the adsorption holes 111 to adsorb and fix the composite adhesive film 01 onto the conveyor belt 11, ensuring that the composite adhesive film 01 will not wrinkle or shift during transportation; subsequently, as shown in the attached diagram... Figure 6 As shown, the vacuum section continuously outputs negative pressure through the insulating hole 011, adsorbing and pressing the solar cell 02 onto the composite film 01, ensuring a tight fit between the solar cell 02 and the composite film 01. Throughout the entire conveying process, the solar cell 02 and the composite film 01 maintain a relatively fixed positional relationship, completely eliminating slippage caused by the start / stop of the conveyor belt 11 or changes in its running speed. This negative pressure adsorption fixing method replaces the traditional method of physically pressing the solar cell 02 with a pressure fixture, fundamentally avoiding the risk of solar cell 02 cracking caused by uneven pressure from the pressure fixture and misalignment of the fixture, effectively improving the overall yield rate in the photovoltaic module production process.

[0096] In a preferred embodiment, the photovoltaic module manufacturing equipment also includes a composite mechanism 3 for pressing a portion of the solder ribbon 03 into the adhesive film 04 to form a composite adhesive film 01. It is particularly important to note that only a portion of the solder ribbon 03 is embedded in the adhesive film 04, while the other portion remains exposed outside the adhesive film 04 and makes ohmic contact with the solar cell 02, ensuring that the electrical energy generated by the solar cell 02 can be efficiently and non-destructively collected and discharged.

[0097] As attached Figures 7 to 11 As shown, the composite mechanism 3 includes a composite platform 31, a pressure roller support 32, and several rotating pressure rollers 33. The composite platform 31 is used to lay the adhesive film 04. A support plane is provided on the side of the composite platform 31 facing the rotating pressure rollers 33, and the adhesive film 04 is laid flat on the support plane to ensure the horizontality of the adhesive film 04. The pressure roller support 32 is fixedly mounted on the composite platform 31. All rotating pressure rollers 33 are rotatably mounted on the pressure roller support 32, and all rotating pressure rollers 33 are linearly distributed along the length of the composite adhesive film 01, with all rotating pressure rollers 33 located above the composite platform 31. The composite mechanism 3 adopts a progressive method, using each stage of rotating pressure rollers 33 to gradually press a portion of each welding strip 03 into the adhesive film 04 to form the composite adhesive film 01. That is, each stage of rotating pressure rollers 33 only completes a portion of the downward pressing stroke, allowing the welding strip 03 and the battery cell 02 to gradually adapt to deformation, avoiding instantaneous and severe stress impacts that could damage the welding strip 03 and cause cracks, thus improving the yield rate.

[0098] In a preferred embodiment, the surface of the rotating pressure roller 33 is provided with guide grooves 331. All guide grooves 331 are evenly distributed along the width direction of the composite adhesive film 01, used to guide the welding strip 03 to move along the length direction of the composite adhesive film 01, and to limit the welding strip 03 from deviating along the width direction of the composite adhesive film 01 under the action of external force, thereby preventing the welding strip 03 from deviating from the preset embedding position, ensuring the horizontality of the welding strip 03, and ensuring that the exposed part of the welding strip 03 forms a stable and reliable contact with the battery cell 02. Specifically, the guide groove 331 is an annular groove, and each guide groove 331 is provided with one welding strip 03. It is particularly important to note that the radial depth of the guide groove 331 is less than the diameter of the welding strip 03, so that part of the welding strip 03 is exposed outside the guide groove 331, ensuring that each welding strip 03 is not completely pressed into the adhesive film 04.

[0099] In a preferred embodiment, the composite mechanism 3 further includes a solder strip guide block 34 and a heating module 35. The solder strip guide block 34 is fixed to the composite platform 31 and has several wire-passing holes 341. A solder strip 03 is passed through each wire-passing hole 341. The wire-passing holes 341 are used to guide the solder strip 03 into the guide groove 331 along the length direction of the composite adhesive film 01. Specifically, a U-shaped guide groove is formed on the side of the solder strip guide block 34 facing the composite platform 31. Two rows of wire-passing holes 341 are provided on both sides of the U-shaped guide groove. Each row of wire-passing holes 341 is evenly distributed along the width direction of the composite adhesive film 01. The heating module 35 is fixed to the solder strip guide block 34. Before the solder strip 03 is laminated with the adhesive film 04, the heating module 35 preheats the solder strip 03 in each wire-passing hole 341 to ensure that the adhesion between the solder strip 03 and the adhesive film 04 is increased during the lamination process, thereby improving the lamination effect.

[0100] As a preferred embodiment, as shown in the appendix Figure 12 and 13 As shown, the photovoltaic module manufacturing equipment also includes a support frame 4 and a feeding mechanism 5 fixed to the end of the support frame 4. The feeding mechanism 5 is used to continuously supply welding strips 03 and encapsulant film 04 respectively, realizing connected feeding and improving production efficiency. The feeding mechanism 5 includes several welding strip guide rollers 52, and an encapsulant film roller 51 is rotatably mounted at the end of the support frame 4. The encapsulant film roller 51 releases the wound encapsulant film 04 by rotating, so that the encapsulant film 04 is laid on the composite platform 31 under the traction of the conveying mechanism 1. All welding strip guide rollers 52 are located above the encapsulant film roller 51, and the welding strip guide rollers 52 are provided with several welding strip guide grooves, which are used to guide multiple welding strips 03 into each wire-threading hole 341 respectively.

[0101] As a preferred embodiment, as shown in the appendix Figures 14 to 16 As shown, the photovoltaic module manufacturing equipment also includes a laying mechanism 6 fixed to the support frame 4 and located above the conveying mechanism 1, for laying the solar cells 02 onto the composite film 01. The composite platform 31 and the adsorption base plate 21 are both laid flat on the support frame 4 and can be fixed to the support frame 4 with bolts.

[0102] The laying mechanism 6 includes a laying suction cup 61, a laying cylinder 62, a moving slider 63, a transmission screw 64, a laying bracket 65, and a transverse guide rod 66. The laying suction cup 61 is located above the conveyor belt 11, and it lays the battery cells 02 onto the composite film 01 using negative pressure. There is more than one laying suction cup 61, and each laying suction cup 61 adsorbs one battery cell 02. All laying suction cups 61 are distributed along the length of the composite film 01, enabling the simultaneous laying of multiple battery cells 02, resulting in high production efficiency. The laying cylinder 62 is fixedly connected to the laying suction cup 61 and is used to drive the laying suction cup 61 to move up and down along the thickness of the composite film 01, allowing the laying suction cup 61 to move downwards to release material or upwards to retrieve material. The movable slider 63 is fixedly connected to the laying cylinder 62. The movable slider 63 is used to drive the laying suction cup 61 to move along the width direction of the composite film 01 through the laying cylinder 62. The transmission screw 64 passes through the movable slider 63 along the width direction of the composite film 01, and is used to drive the movable slider 63 to move along the width direction of the composite film 01. This ensures that the laying suction cup 61, driven by the movable slider 63, aligns the adsorbed battery cell 02 with the laying position of the composite film 01, improving the positioning accuracy of the laying suction cup 61 and thus improving the yield rate. The laying bracket 65 is a portal bracket and is fixed to the adsorption base plate 21. The transmission screw 64 is fixed to the laying bracket 65. In addition, a laying motor is fixed to one side of the laying bracket 65. The laying motor is connected to the transmission screw 64 and drives the transmission screw 64 to rotate. A transverse guide rod 66 is fixed to the laying bracket 65 and is slidably engaged with the movable slider 63. The transverse guide rod 66 guides the movable slider 63 to move along the width direction of the composite adhesive film 01, improving the positional accuracy of the laying suction cup 61. In addition, the transverse guide rail and the transmission screw 64 pass through both sides of the movable slider 63 respectively, ensuring that the movable slider 63 is evenly stressed on both sides, preventing the laying suction cup 61 from accidentally swinging due to unstable stress on both sides during the laying process, improving laying accuracy, and thus improving the yield rate.

[0103] In addition, a position sensor can be mounted on the laying mechanism 6 to accurately detect the position of the laying suction cup 61 in a closed-loop control manner, ensuring that the battery cell 02 is aligned with the target laying position of the composite film 01 each time it is laid, resulting in high laying accuracy and improving the yield rate.

[0104] As a preferred embodiment, as shown in the appendix Figures 18 to 20 As shown, the photovoltaic module manufacturing equipment also includes an opening mechanism 7 fixed to the support frame 4 and located between the composite mechanism 3 and the laying mechanism 6. Before laying the solar cells 02, the opening mechanism 7 is used to open insulating holes 011 in the composite film 01, as shown in the attached figure. Figure 21 As shown; the composite plate 31 is provided with a number of clearance holes 311, all of which are used to avoid the opening pins 711 of the cutter head 71. This ensures that the opening pins 711 bend and pierce the composite adhesive film 01, and also prevents the opening pins 711 from colliding with the composite plate 31.

[0105] The perforation mechanism 7 includes a cutter head 71, a perforation cylinder 72, and a perforation bracket 73. The cutter head 71 is fixedly equipped with a plurality of perforation needles 711, which are used to pierce the composite adhesive film 01 to form insulating holes 011. The cutter head 71 is located above the composite platform 31 until all the perforation needles 711 and all the clearance holes 311 are aligned one-to-one along the thickness direction of the composite adhesive film 01, ensuring that each perforation needle 711 is inserted into its corresponding clearance hole 311. The perforation cylinder 72 is fixedly connected to the cutter head 71 and is used to drive the cutter head 71 to move up and down along the thickness direction of the composite adhesive film 01, so that the perforation needles 711 pierce or detach from the composite adhesive film 01. The perforation bracket 73 is fixedly mounted on the composite platform 31, and the perforation cylinder 72 is fixedly mounted on the perforation bracket 73. The perforation bracket 73 is preferably a portal frame bracket, providing space for the movement of the cutter head 71.

[0106] As a preferred embodiment, as shown in the appendix Figure 22 As shown, the photovoltaic module manufacturing equipment also includes a welding mechanism 8 fixed to the adsorption base plate 21. The welding mechanism 8 includes a light box 81 and several welding lamps 82. The light box 81 is fixed to the adsorption base plate 21. All the welding lamps 82 are arranged in the light box 81 along the width direction of the composite film 01. The welding lamps 82 are used to bond the battery cells 02 to the composite film 01 by heating to form a battery string, ensuring that the grid lines of the battery cells 02 are tightly connected to the exposed solder strips 03 of the composite film 01. The welding lamps 82 are preferably infrared lamps, and all the welding lamps 82 are evenly spaced.

[0107] As a preferred embodiment, as shown in the appendix Figure 23 and 24 As shown, the photovoltaic module manufacturing equipment also includes a cooling mechanism 9 fixed to the adsorption base plate 21. The cooling mechanism 9 is used to cool the battery strings. The cooling mechanism 9 includes a cooling box 91, which is fixed to the adsorption base plate 21. A cooling chamber is formed inside the cooling box 91. An air inlet 911 is provided on one side of the cooling box 91, which is connected to the cooling chamber. The cooling chamber is opposite to the battery strings. Low-temperature cold air blown in through the air inlet 911 is blown through the cooling chamber to the battery strings, cooling them down. This causes the adhesive film 04 to shrink rapidly, increasing the clamping force of the adhesive film 04 on the solder ribbon 03 and improving the contact strength between the solder ribbon 03 and the battery cell 02, thereby improving the yield. The cooling mechanism 9 also includes an air inlet pipe connected to the air inlet 911 and a cooling module connected to the air inlet pipe. The cooling module provides low-temperature cold air to the cooling chamber through the air inlet pipe.

[0108] As a preferred embodiment, as shown in the appendix Figure 24 and 25As shown, the photovoltaic module manufacturing equipment also includes a slitting mechanism 10 fixed to the adsorption base plate 21. The slitting mechanism 10 includes a blade holder 101, a lower blade head 102, an upper blade head 103, and a slitting cylinder 104. The blade holder 101 is fixed to the adsorption base plate 21 and forms a slitting platform 1011 for passing through cooled battery strings.

[0110] The working principle of the photovoltaic module manufacturing equipment provided by this utility model is as follows:

[0111] The film 04 roller of the feeding mechanism 5 rotates to release the film 04. The film 04 is laid flat on the composite table 31 under the traction of the conveying mechanism 1. At the same time, the welding strip guide roller 52 guides multiple welding strips 03 to enter each wire hole 341 of the welding strip guide block 34, and heats the welding strips 03 in each wire hole 341 using the heating module 35.

[0112] Under the guidance of the wire threading hole 341, the welding strip 03 enters the composite mechanism 3 along the length direction of the composite film 01. The rotating pressure roller 33 presses part of the welding strip 03 into the film 04 with the help of the guide groove 331 to form the composite film 01.

[0113] The opening cylinder 72 of the opening mechanism 7 drives the cutter disc 71 to move up and down along the thickness direction of the composite adhesive film 01, and the opening needle 711 pierces the composite adhesive film 01 to form an insulating hole 011.

[0114] The transmission screw 64 of the laying mechanism 6 drives the laying suction cup 61 to move along the width direction of the composite film 01 through the moving slider 63. The laying cylinder 62 drives the laying suction cup 61 to rise and fall along the thickness of the composite film 01. The laying suction cup 61 lays the battery cell 02 on the composite film 01.

[0115] The welding lamp 82 of the welding mechanism 8 heats and bonds the battery cell 02 to the composite adhesive film 01 to form a battery string. The cooling mechanism 9 cools and lowers the temperature of the battery string. The slitting mechanism 10 slits the cooled battery string.
