Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module manufacturing technology, specifically relating to a busbar bending device. Background Technology

[0002] Solar cells are connected in series and then processed through stacking, lamination, and encapsulation to form a photovoltaic module. Specifically, multiple solar cells are connected in series by solder strips to form a cell string. Then, the multiple cell strings are arranged according to the required photovoltaic module layout and laminated. The current is collected in the junction box by welding the busbars to the solder strips at the ends of the multiple cell strings, thereby providing power to the outside world.

[0003] Busbars are typically made of tinned copper strip and are usually L-shaped. The longer side of the L-shaped busbar connects to the battery string, while the shorter side connects to the junction box. Currently, busbar bending is always done from the front. That is, the shorter side of the L-shaped busbar is flush with the back of the backplate, while the longer side passes through a through-hole on the backplate and is positioned above the backplate. A bending device is used to bend the busbar above the backplate, ensuring it is flush with the front of the backplate. Typically, two busbars pass through one through-hole on the backplate, and the bending device is used to bend the two busbars above the backplate in opposite directions.

[0004] For back-contact solar cells, the busbars need to be bent below the backsheet. However, when the busbars below the backsheet are misaligned, existing bending devices cannot effectively bend them. When the two busbars below the backsheet are in an ideal position, i.e., without misalignment (e.g....),... Figure 1 As shown), existing bending devices can effectively bend two busbars in opposite directions below the back plate. However, when the incoming busbars are deflected below the back plate (e.g.), Figure 2 As shown, the existing bending device cannot bend the two busbars under the back plate. Utility Model Content

[0005] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a busbar bending device, which, with the cooperation of the upper and lower distributing mechanisms, can effectively bend the busbar below the back plate.

[0006] To achieve the above objectives, this utility model provides a busbar bending device, which includes an upper distributing mechanism located above the back plate and a lower distributing mechanism located below the back plate.

[0007] The upper distribution mechanism includes a first lifting assembly and an upper distribution section connected to the power output end of the first lifting assembly;

[0008] The lower shifting mechanism includes a second lifting assembly and a lower shifting assembly. The lower shifting assembly includes a mounting base connected to the power output end of the second lifting assembly and a first sliding shifting component and a second sliding shifting component arranged in parallel on the mounting base. The first sliding shifting component includes a first sliding guide portion mounted on the mounting base and a first shifting portion mounted on the first sliding guide portion. The second sliding shifting component includes a second sliding guide portion mounted on the mounting base and a second shifting portion mounted on the second sliding guide portion.

[0009] Initially, the first and second gear shifting sections approach each other and form a gear shifting gap for the upper gear shifting section to insert into;

[0010] When bending the two busbars in the outlet hole on the back plate, the first lifting assembly drives the upper dispensing part to move downward, so that the upper dispensing part passes through the outlet hole and inserts between the two busbars. The second lifting assembly drives the lower dispensing assembly to move upward, so that the upper dispensing part inserts into the dispensing gap. The lower dispensing assembly continues to move upward, so that the first sliding guide and the second sliding guide move in opposite directions, so that the first dispensing part and the second dispensing part move away from each other, bending the two busbars on both sides of the upper dispensing part in opposite directions.

[0011] As a further improvement of this utility model, a wedge-shaped tip is provided at one end of the upper dispensing part near the lower dispensing mechanism.

[0012] As a further improvement of this utility model, the first sliding guide includes a first slide rail and a first slider.

[0016] As a further improvement of this utility model, a flattening mechanism is also provided below the back plate. The flattening mechanism includes a pressing piece, which presses the bent busbar.

[0018] The busbar bending device further includes a translation component, and the second lifting component is installed at the power output end of the translation component. After the busbar is bent, the translation component drives the second lifting component to move so that the pressing plate is facing the bent busbar. The second lifting component drives the pressing plate to press the busbar upward.

[0019] As a further improvement of this utility model, the flattening mechanism also includes a third lifting component. The pressing plate is installed at the power output end of the third lifting component.

The end of the connecting rod away from the mounting base is rotatably connected to the free end close to the pressing section. A second limiting block is provided on the outer side of the mounting base near the free end of the limiting section.

[0022] The connecting rod is provided with a spring mounting seat, and the spring mounting seat and the free end of the pressing section are connected by a pressing spring;

[0023] When the pressing plate presses the manifold upward, the pressing spring is compressed, and the pressing plate rotates relative to the connecting rod, causing the free end of the limiting segment to rotate outward until it abuts against the second limiting block.

[0024] As a further improvement of this utility model, the flattening mechanism includes a mounting plate, and two pressing pieces are provided. The two pressing pieces are arranged side by side on the mounting plate along a direction perpendicular to the back plate conveying direction. Each pressing piece presses a bent busbar.

[0028] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0029] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0030] (1) In the busbar bending device of this utility model, the upper splitting part moves downward and passes through the lead-out hole to insert between two busbars. Then the lower splitting assembly moves upward to make the upper splitting part insert into the splitting gap. The lower splitting assembly continues to move upward to make the first sliding guide part and the second sliding guide part move in opposite directions, so that the first splitting part and the second splitting part move away from each other, and bend the two busbars on both sides of the upper splitting part in opposite directions, thereby effectively bending the busbars.

[0031] (2) The busbar bending device of this utility model provides a first compression spring and a second compression spring corresponding to the first slider and the second slider respectively, so that the first slider and the second slider can return to their original positions after the busbar is bent, saving power and ready for the next separation and bending.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0043] Furthermore, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise expressly and specifically limited.

[0044] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0046] The backplate has multiple lead-out holes, and each lead-out hole contains two busbars. For back-contact solar cells, the shorter side of the two L-shaped busbars faces the opposite direction and is in contact with the front of the backplate, while the longer side passes through the lead-out hole and is located below the backplate.

[0047] Example:

[0048] Please see Figures 3-6 The preferred embodiment of the present invention includes an upper splitting mechanism located above the back plate and a lower splitting mechanism and a flattening mechanism located below the back plate. The upper splitting mechanism and the lower splitting mechanism cooperate to effectively bend the two busbars 12 passing through the lead-out holes located below the back plate, and the flattening mechanism presses and shapes the bent busbars 12.

[0049] Specifically, such as Figures 3-4 As shown, the upper distribution mechanism includes a first lifting assembly 2 and an upper distribution section 1 connected to the power output end of the first lifting assembly 2. The first lifting assembly 2 drives the upper distribution section 1 to move up and down, allowing the upper distribution section 1 to extend through the outlet hole and between the two busbars 12 for distribution and shaping. Preferably, the upper distribution section 1 has a wedge-shaped tip at one end near the lower distribution mechanism.

[0050] Furthermore, the lower distribution mechanism includes a second lifting assembly 4 and a lower distribution assembly 3, wherein the lower distribution assembly 3 includes a mounting base 307 connected to the power output end of the second lifting assembly 4 and a first sliding distribution member and a second sliding distribution member arranged in parallel on the mounting base 307.

[0051] Specifically, the first sliding distributor includes a first sliding guide portion mounted on the mounting base 307 and a first distributor portion 301 mounted on the first sliding guide portion, and the second sliding distributor includes a second sliding guide portion mounted on the mounting base 307 and a second distributor portion 302 mounted on the second sliding guide portion.

[0052] Initially, the first dispensing part 301 and the second dispensing part 302 approach each other, forming a dispensing gap between them for the upper dispensing part 1 to insert into. When bending the two busbars 12 in the lead-out holes on the back plate 11, the first lifting assembly 2 drives the upper dispensing part 1 to move downward, so that the upper dispensing part 1 passes through the lead-out holes and inserts between the two busbars 12 to dispense the busbars 12. The second lifting assembly 4 drives the lower dispensing assembly 3 to move upward, so that the upper dispensing part 1 is inserted into the dispensing gap. The lower dispensing assembly 3 continues to move upward, and under the action of the upper dispensing part 1, the first dispensing part 301 and the second dispensing part 302 move away from each other. The first sliding guide and the second sliding guide move in opposite directions, thereby bending the two busbars 12 on both sides of the upper dispensing part 1 in opposite directions.

[0053] Preferably, the first sliding guide includes a first slide rail 303 and a first slider 304. The first slide rail 303 extends along a direction perpendicular to the conveying direction of the back plate 11 and is disposed on the mounting base 307. The first slider 304 is slidably connected to the first slide rail 303 and the first distributing part 301 is disposed on the first slider 304 so as to slide under the guidance of the first slide rail 303.

[0054] Preferably, the second sliding guide includes a second slide rail 305 and a second slider 306. The second slide rail 305 extends along a direction perpendicular to the conveying direction of the back plate 11 and is disposed on the mounting base 307, and is disposed side by side with the first slide rail 303 along a direction perpendicular to the conveying direction of the back plate 11. The second slider 306 is slidably connected to the second slide rail 305, and the second distributor 302 is connected to the second slider 306 so as to slide under the guidance of the second slide rail 305.

[0055] Preferably, a first mounting plate 310 and a second mounting plate 311 are respectively provided at one end of the mounting base 307 near the first sliding guide and at one end near the second sliding guide; at the same time, a first compression spring 308 is provided between the first slider 304 and the first mounting plate 310, and a second compression spring 309 is provided between the second slider 306 and the second mounting plate 311; when the first slider 304 and the second slider 306 move in opposite directions, the first compression spring 308 and the second compression spring 309 are compressed respectively, and can move in opposite directions and return to their original positions under the action of the elastic restoring force of the first compression spring 308 and the second compression spring 309, thus saving power.

[0056] Preferably, a first limiting block is provided at both ends of the mounting base 307 along the conveying direction of the back plate 11, and the two first limiting blocks are respectively located on both sides of the lower dispensing assembly 3, so as to limit the position of the busbar 12 when it is bent in the opposite direction, so that the busbar 12 bends along the preset path and prevents the position of the busbar 12 from shifting during the bending process.

[0057] During operation, the backplate 11 is conveyed via a conveying device between the upper and lower sorting mechanisms, such as... Figure 3 As shown, it is adsorbed and fixed on the conveying device or adsorption platform to prevent the back plate 11 from moving during the sorting and pressing process. When the outlet hole is directly below the upper sorting part 1, the upper sorting part 1 moves downward under the drive of the first lifting assembly 2, and the wedge-shaped tip of the upper sorting part 1 passes through the outlet hole and inserts between the two busbars 12, as shown. Figure 4As shown, the two busbars 12 located below the back plate can be separated by the upper disengagement part 1, regardless of whether their positions are deflected. Then, the second lifting assembly 4 drives the lower disengagement assembly 3 to move upward, and the upper disengagement part 1 inserts into the disengagement gap formed between the first disengagement part 301 and the second disengagement part 302, and continues to drive the lower disengagement assembly 3 to move upward, so that the upper disengagement part 1 separates the first disengagement part 301 and the second disengagement part 302 to both sides along the disengagement gap, and the first slider 3... 04 and the second slider 306 slide in a direction away from each other, and the first compression spring 308 and the second compression spring 309 on both sides are compressed. Correspondingly, during this process, the two busbars 12 located outside the upper splitter 1 are gradually bent as the first splitter 301 and the second splitter 302 move away from each other. When the first splitter 301 and the second splitter 302 abut against the back of the back plate 11, the second lifting assembly 4 stops moving. At this time, the lower ends of the two busbars 12 are bent about 90° in opposite directions.

[0058] After the initial bending action is completed, the upper shifting part 1 moves upward to return to its initial position (above the back plate 11). During this process, the first compression spring 308 and the second compression spring 309 gradually return to their initial state, and the first shifting part 301 and the second shifting part 302 also return to their initial state of being close to each other. Then, the second lifting assembly 4 drives the lower shifting assembly 3 to move downward to return to its initial position, ready for the next shifting action.

[0059] It is understandable that during the above process, the first dispensing part 301 and the second dispensing part 302 are always in a pre-tensioned state under the action of the first compression spring 308 and the second compression spring 309, respectively.

[0060] After the busbar 12 is bent by the cooperation of the upper and lower splitting mechanisms, the bent busbar 12 may not reach the ideal angle. Therefore, this application can perform a second bending and shaping on the bent busbar 12 so that the busbar 12 is bent as much as possible by 90°, so that the busbar 12 fits as closely as possible to the back of the back plate 11.

[0061] Specifically, in a preferred embodiment, the busbar bending device further includes a flattening mechanism disposed below the back plate 11. The flattening mechanism includes a pressing plate 5, which presses and shapes the bent busbar 12 to ensure a good fit between the busbar 12 and the back of the back plate 11. In actual installation, the pressing plate 5 can be configured as a single unit, pressing both bent busbars 12 simultaneously with one pressing plate, or as follows... Figures 5-6Two pressing pieces 5 are arranged side by side along a direction perpendicular to the conveying direction of the back plate 11, and each pressing piece 5 presses a bent busbar 12.

[0062] In one specific embodiment of this utility model, the pressing piece 5 is disposed on the mounting base 307 so as to drive the lower dispensing component 3 and the pressing piece 5 to move up and down simultaneously through the second lifting component 4; at the same time, a translation component is also provided, and the second lifting component 4 is installed on the power output end of the translation component, so that after the lower dispensing component 3 bends the busbar 12, the second lifting component 4 is moved through the translation component, so that the pressing piece 5 is facing the bent busbar 12, and under the drive of the second lifting component 4, the pressing piece 5 presses the busbar 12 upward.

[0063] In another specific embodiment of this utility model, such as Figure 5 and Figure 6 As shown, the flattening mechanism is also equipped with a third lifting component 6, and the pressing plate 5 is installed at the power output end of the third lifting component 6 so that after the bent manifold 12 is above the pressing plate 5, the pressing plate 5 is driven to move upward to press the manifold 12 by the third lifting component 6.

[0064] In actual setup, the flattening mechanism can be positioned in front of the lower splitting mechanism along the conveying direction of the back plate. After the upper splitting mechanism, in conjunction with the lower splitting mechanism, bends the busbar 12, the positions of the lower splitting mechanism and the flattening mechanism remain unchanged. The back plate 11 is moved by the conveying device, so that the bent busbar 12 is positioned above the pressing plate 5. Then, the pressing plate 5 is driven upward by the third lifting assembly 6 to press the bent busbar 12. Alternatively, a translation assembly can be set separately, with the second lifting assembly 4 and the third lifting assembly 6 both positioned at the power output end of the translation assembly. This allows the translation assembly to drive the lower splitting assembly 3 and the pressing plate 5 to move sequentially below the busbar 12, bending and pressing the busbar 12 in sequence.

[0065] In actual setup, the first lifting component 2, the second lifting component 4, the third lifting component 6, and the translation component can all be cylinders.

[0066] It is understandable that when the manifold 12 is pressed and shaped using the pressing pad 5, the upper distributor 1 can either move upwards to return to its initial position or remain with one end still below the back plate 11. Correspondingly, if there is only one pressing pad 5, and the upper distributor 1 is still below the back plate 11, a pressing gap can be reserved at the position of the pressing pad 5 corresponding to the upper distributor 1 to avoid obstructing the upper distributor 1. This ensures that when the pressing pad 5 moves upwards to perform the pressing action, the upper distributor 1 inserts into the pressing gap, thus not affecting the pressing and shaping action. If there are two pressing pads 5, a pressing gap can be selected between the two pressing pads 5 depending on whether the upper distributor 1 returns to its original position during the pressing action.

[0067] Preferably, two pressing pads 5 are used to press the two busbars 12, and a pressing gap is provided between the two pressing pads 5.

[0068] Specifically, when the pressing piece 5 is set on the mounting base 307, each pressing piece 5 includes a pressing section 501 and a limiting section 502; wherein, the limiting section 502 is set vertically, one end of which is set as a free end close to the mounting base 307, and a second limiting block 8 is set on the outside of the free end of the mounting base 307 close to the limiting section 502, and the other end of the limiting section 502 is connected to the connecting end of the pressing section 501 as a connecting end; the pressing section 501 is set in a direction perpendicular to the conveying direction of the back plate 11, and a connecting rod 9 is vertically installed in the middle of the mounting base 307, and the end of the connecting rod 9 away from the mounting base 307 is rotatably connected to the free end close to the pressing section 501; at the same time, a spring mounting seat 10 is set on the connecting rod 9, and the spring mounting seat 10 is connected to the free end of the pressing section 501 by a pressing spring 7.

[0069] When the pressing piece 5 is installed at the power output end of the third lifting assembly 6, a mounting plate is connected to the power output end of the third lifting assembly 6 to correspond to the installation of the pressing piece 5. Two pressing pieces 5 are arranged side by side on the mounting plate along a direction perpendicular to the conveying direction of the back plate 11. Each pressing piece 5 includes a pressing section 501 and a limiting section 502. The limiting section 502 is vertically arranged, with one end serving as a free end close to the mounting plate. A second limiting block 8 is provided on the outside of the free end of the limiting section 502 on the mounting plate. The other end of the limiting section 502 serves as a connecting end and is connected to the connecting end of the pressing section 501. The pressing section 501 is arranged along a direction perpendicular to the conveying direction of the back plate 11. A connecting rod 9 is vertically installed in the middle of the mounting plate. The end of the connecting rod 9 away from the mounting seat 307 is rotatably connected to the free end close to the pressing section 501. At the same time, a spring mounting seat 10 is provided on the connecting rod 9, and the spring mounting seat 10 is connected to the free end of the pressing section 501 by a pressing spring 7.

[0070] After the bent busbar 12 is positioned above the pressing plate 5, the two pressing plates 5 move upwards, pressing the corresponding bent busbar 12 onto the lower surface of the back plate 11. As the pressing plate 5 continues to move upwards, the pressing spring 7 is compressed, and the pressing plate 5 rotates relative to the connecting rod 9. The end of the pressing section 501 near the limiting section 502 tilts upwards, and the free end of the limiting section 502 rotates outwards until it abuts against the corresponding second limiting block 8, at which point the pressing plate 5 stops pressing. During this process, the pressing plate 5 will first contact the adjacent parts of the bent busbar 12 on the back side, and then press and shape it. This method can make the pressing and shaping effect better. At the same time, the rotation of the pressing plate 5 is limited by the setting of the second limiting block 8 to prevent the pressing plate 5 from over-pressing the busbar 12, thereby avoiding damage to the back plate 11.

[0071] The busbar bending device of this utility model has a simple structure, reasonable design, stable distribution, strong compatibility, and can save power, realizing fast and effective bending of busbars. It has good application prospects and promotion value.

[0072] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
