Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic module production, and particularly to a device for adjusting and cutting special-shaped solder ribbon nodes of a photovoltaic module. Background Art

[0002] With the continuous development of solar cell and module technologies, new module technologies have emerged continuously. In the current string soldering process, round solder ribbons are usually used to connect the front and back sides of adjacent two solar cells in series. Among them, in order to improve the light reception rate of the front side of the solar cell, the solder ribbon on the front side of the solar cell is designed as a triangle, and in order to reduce the soldering difficulty and reliability of the solder ribbon on the back side of the solar cell, the solder ribbon on the back side of the solar cell is designed as a flat shape. In addition, flat solder ribbons are also used for transitional connection between adjacent two solar cells, thus forming a special-shaped solder ribbon with continuous extension of triangular segments and flat segments at intervals.

[0003] However, in actual production, due to the differences in solder ribbon materials and the accumulation of errors during the cutting process, the solder ribbon nodes (transition points between triangular ribbons and flat ribbons) will shift.

Detailed implementation manners

[0065] In the description of this embodiment, it should be understood that the orientation or positional relationships indicated by the terms "length", "width", "height", "upper", "lower", "left", "right", "vertical", "horizontal", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention.

[0066] As a specific embodiment of the present invention, as Figure 1 shown, the present invention provides a photovoltaic special - shaped welding tape node adjustment and cutting device, which may include: a frame 100, a pressing and straightening module 300, a moving adjustment module 400, and a welding tape cutting module 500.

[0067] Among them, the pressing and straightening module 300, the moving and adjusting module 400, and the solder strip cutting module 500 are sequentially arranged on the frame 100 along the first direction. The pressing and straightening module 300 includes at least one first pressing and straightening module 310 and a second pressing and straightening module 320 arranged along the first direction. At least one first pressing and straightening module 310 is movably arranged on the frame 100 along the first direction, and the second pressing and straightening module 320 is fixedly arranged on the frame 100.

[0068] That is to say, for the photovoltaic special-shaped solder strip node adjustment and cutting device according to the embodiment of the present invention, the pressing and straightening module 300, the moving and adjusting module 400, and the solder strip cutting module 500 are sequentially arranged on the frame 100 along the first direction. It should be noted that the first direction is the feeding direction of the solder strip (as shown by the arrow in Figure 1 ). Among them, the pressing and straightening module 300 further includes at least one first pressing and straightening module 310 and a second pressing and straightening module 320 arranged along the first direction. The second pressing and straightening module 320 is used to fixedly press the solder strip fed along the first direction, and at least one first pressing and straightening module 310 is used to press the solder strip and move in the opposite direction of the first direction, thereby achieving the purpose of straightening the solder strip. The moving and adjusting module 400 is used to press the solder strip fed along the first direction and move and adjust the node position of the solder strip in the first direction, so that each node is on the same straight line during the feeding process of each solder strip, facilitating the subsequent cutting by the solder strip cutting module 500.

[0069] Specifically, for the photovoltaic special-shaped solder strip node adjustment and cutting device according to the present invention, through the coordinated work of the pressing and straightening module 300, the moving and adjusting module 400, and the solder strip cutting module 500 arranged on the frame 100 along the first direction, first, the moving and adjusting module 400 presses the fed solder strip and moves along the feeding direction to align the nodes of the solder strip, then the pressing and straightening module 300 presses and straightens the solder strip after the nodes are aligned, and finally the solder strip cutting module 500 cuts at a predetermined position. Thereby, it can be ensured that the special-shaped solder strip does not turn over or shift during the traction cutting process, and good string connection can be ensured after the solder strip is straightened.

[0070] It should be noted that a visual recognition module 200 is further arranged on one side of the frame 100 of the photovoltaic special-shaped solder strip node adjustment and cutting device according to the embodiment of the present invention. It mainly includes a CCD camera module and an LED backlight module. The special-shaped solder strip passes between the camera and the light source. The camera captures the position information of the solder strip nodes and sends instructions to the pressing and straightening module 300 and the moving and adjusting module 400.

[0071] In some embodiments, such as Figures 1 to 3As shown, the first pressing and straightening module 310 and the second pressing and straightening module 320 may both include: a first mounting base 330, a wire pressing assembly 340, and a pre-tightening assembly 350. Among them, the first mounting base 330 is provided on the frame 100. The wire pressing assembly 340 and the pre-tightening assembly 350 are sequentially arranged on the first mounting base 330 along the first direction. Among them, the first pressing and straightening module 310 further includes a moving module 600. The moving module 600 is arranged on the frame 100 along the first direction. At least one first pressing and straightening module 310 is connected to the moving module 600 through the first mounting base 330, and the moving module 600 drives the first pressing and straightening module 310 to move along the first direction.

[0072] Specifically, the first pressing and straightening module 310 is connected to the moving module 600 through the first mounting base 330, and thus can move along the first direction on the frame 100, while the second pressing and straightening module 320 is fixedly arranged on the frame 100 through the first mounting base 330. Among them, the wire pressing assembly 340 in the first pressing and straightening module 310 and the second pressing and straightening module 320 is used to press the fed special-shaped welding tape, and the pre-tightening assembly 350 is used to pre-tighten and limit the fed welding tape to prevent it from shifting and folding during the traction and straightening process.

[0073] In some embodiments, as Figures 2 to 4 shown, the wire pressing assembly 340 may include: a first substrate 341, a fixing frame 342, a first driving cylinder 343, a cylinder driving adapter plate 344, a second mounting base 345, and a wire pressing block 347. Among them, the first substrate 341 is arranged on the top surface of the first mounting base 330. The fixing frame 342 is arranged on the first mounting base 330 and is located above the first substrate 341. The first driving cylinder 343 is connected to the fixing frame 342 and its driving rod faces downward. The cylinder driving adapter plate 344 is connected to the end of the driving rod of the first driving cylinder 343. A plurality of wire pressing shafts 346 penetrate through the second mounting base 345 in the thickness direction. The second mounting base 345 is connected to the bottom surface of the cylinder driving adapter plate 344 and there is a spaced space formed between the second mounting base 345 and the cylinder driving adapter plate 344. One end of the plurality of wire pressing shafts 346 is movably arranged in the spaced space, and the other end of the plurality of wire pressing shafts 346 extends downward through the second mounting base 345. The wire pressing block 347 is connected to the extending end of the wire pressing shaft 346. A first spring 348 is sleeved on the wire pressing shaft 346 between the wire pressing block 347 and the second mounting base 345, and the wire pressing block 347 is arranged above the first substrate 341.

[0074] Specifically, a fixing frame 342 is installed on the first mounting base 330. The first driving cylinder 343 is hung on the fixing frame 342 with its driving rod facing downward. The end of the driving rod of the first driving cylinder 343 is connected to a cylinder driving adapter plate 344, and a second mounting base 345 is connected to the bottom surface of the cylinder driving adapter plate 344. A plurality of wire pressing shafts 346 are movably inserted through the second mounting base 345. One end of the wire pressing shaft 346 is movable within the spaced space between the cylinder driving adapter plate 344 and the second mounting base 345, and the other end extends out of the bottom of the second mounting base 345 and is connected to a wire pressing block 347. A first spring 348 is sleeved on the wire pressing shaft 346 between the wire pressing block 347 and the second mounting base 345. Thus, when the driving rod of the first driving cylinder 343 is driven to extend, the wire pressing block 347 presses the fed solder tape under the action of the first spring 348. When the driving rod retracts, the wire pressing block 347 is lifted upward. Among them, on the one hand, the first spring 348 can effectively buffer the pressing force of the wire pressing block 347 on the solder tape, and on the other hand, it can also reliably press the solder tape.

[0075] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, a wire trough plate 3411 is provided on one side of the first substrate 341 close to the moving adjustment module 400. The pre-tightening assembly 350 may include: a third mounting base 351 and a plurality of micro-moving pressure heads 352. The third mounting base 351 is pressed on the wire trough plate 3411, and its two ends are respectively connected to the first substrate 341. A plurality of micro-moving pressure heads 352 are arranged in the third mounting base 351, and their bottom ends extend out of the third mounting base 351 and abut against the wire trough plate 3411.

[0076] Specifically, the two ends of the third mounting base 351 can magnetically adsorb the first substrate 341 through magnetic blocks to be pressed on the wire trough plate 3411, which is convenient for installation and disassembly. Thus, one end of the plurality of micro-moving pressure heads 352 arranged in the wire trough plate 3411 extending out of the third mounting base 351 can effectively press the special-shaped solder tape on the wire trough plate 3411, realizing pre-tightening and limiting of the special-shaped solder tape, and preventing the special-shaped solder tape from flipping when the first pressing and straightening module 310 moves for pressing and straightening.

[0077] In some embodiments, such as Figure 6 shown, a wire trough 34111 corresponding to the wire pressing block 347 is provided on the wire trough plate 3411, and a pressure head groove 34112 is formed in a part of the wire trough 34111 corresponding to the micro-moving pressure head 3522.

[0078] That is to say, on the wire trough plate 3411, at positions corresponding to the length directions of each wire pressing block 347, wire troughs 34111 are provided, so as to limit the solder tapes pressed by each wire pressing block 347. And at the part of each wire trough 34111 corresponding to the upper part of the micro-moving pressure head 3522, a pressure head groove 34112 adapted to the end of the micro-moving pressure head 3522 is formed. Furthermore, when the micro-moving pressure head 3522 presses down, it can accurately dock with the pressure head groove 34112 to stably pre-tighten the special-shaped solder tape in the wire trough 34111.

[0079] In some embodiments, as Figure 6 shown, the micro-moving pressure head 3522 includes a second spring 3521 and a pressure shaft 3522 that are vertically press-connected in a stepped hole of the third mounting seat 351.

[0080] That is to say, the pressure shaft 3522 is press-connected in the third mounting seat 351 through the second spring 3521. When the third mounting seat 351 is pressed on the wire trough plate 3411, a certain pre-tightening force is applied to the pressure shaft 3522 by the second spring 3521 to apply a top pressure to the special-shaped solder tape in the wire trough 34111, so that there is no relative slip between the special-shaped solder tape, the wire pressing block 347, and the wire trough plate 3411.

[0081] In other words, during the traction process of the special-shaped solder tape, under the action of the groove structure of the wire trough plate 3411 and the micro-moving pressure head 3522, the bottom surface of the solder tape always fits with the wire trough 34111, avoiding the solder tape from folding and shifting during the forward movement.

[0082] In some embodiments, as Figure 7 shown, the moving adjustment module 400 may include: a fourth mounting seat 4100, a pressing mechanism 4200, a first driving mechanism 4300, and a second driving mechanism 4400. Among them, the fourth mounting seat 4100 is arranged on the frame 100. The pressing mechanism 4200 is movably arranged on the fourth mounting seat 4100 along a first direction. The first driving mechanism 4300 is arranged on the fourth mounting seat 4100 to drive the pressing mechanism 4200 to loosen or press. The second driving mechanism 4400 is arranged on the fourth mounting seat 4100 and is connected to the pressing mechanism 4200, and the second driving mechanism 4400 drives the pressing mechanism 4200 to move along the first direction.

[0083] Specifically, the mobile adjustment module 400 of the present invention is provided on the frame 100 through the fourth mounting seat 4100. A first driving mechanism 4300 is arranged on the fourth mounting seat 4100 to drive the pressing mechanism 4200 to loosen or press. A second driving mechanism 4400 is arranged on the fourth mounting seat 4100 and connected to the pressing mechanism 4200 to drive the pressing mechanism 4200 to move in the first direction. That is to say, by adjusting the position of the pressing mechanism 4200 in the solder tape feeding direction, the node position of the solder tape during the transfer process can be effectively and accurately adjusted, so as to meet the cutting requirements.

[0084] In some embodiments, as Figure 7 shown, the fourth mounting seat 4100 may include: a second base plate 4110 and a pair of vertical plates 4120. Among them, the pair of vertical plates 4120 are arranged on the second base plate 4110 at intervals. The pressing mechanism 4200 is movably arranged between the pair of vertical plates 4120, and the first driving mechanism 4300 is arranged above the pair of vertical plates 4120.

[0085] That is to say, the pressing mechanism 4200 is arranged between the pair of vertical plates 4120 on the second base plate 4110. The pressing mechanism 4200 can move between the pair of vertical plates 4120 (i.e., the first direction), and the first driving mechanism 4300 is arranged above the pair of vertical plates 4120 to control the pressing mechanism 4200 to loosen or press.

[0086] In some embodiments, as Figure 8 and Figure 9 shown, the pressing mechanism 4200 includes at least one pressing component 4210 arranged in the second direction, wherein the first direction is perpendicular to the second direction. As an example, the pressing component 4210 can be arranged along the length direction of the vertical plate 4120. The pressing component 4210 may include: a pressing head seat 4211 and a pressing head 4212. Among them, the pressing head seat 4211 is movably arranged between the pair of vertical plates 4120 in the first direction. One end of the pressing head 4212 is pivotally connected to one side of the top surface of the pressing head seat 4211, and the other end of the pressing head 4212 is pressed against the other side of the top surface of the pressing head seat 4211 through a third spring 4213. Among them, the first driving mechanism 4300 extends to drive the other end of the pressing head 4212 to press down so that one end of the pressing head 4212 opens relative to the top surface of the pressing head seat 4211; the first driving mechanism 4300 retracts, and the other end of the pressing head 4212 is reset under the action of the third spring 4213, so that one end of the pressing head 4212 closes relative to the top surface of the pressing head seat 4211.

[0087] That is to say, one or more pressing components 4210 are arranged between a pair of vertical plates 4120 along their length direction to press the welding tapes under various production quantity requirements. Among them, the pressing component 4210 includes a pressing head seat 4211 and a pressing head 4212 pivotally connected to the pressing head seat 4211. The driving end of the pressing head 4212 is connected to the surface of the pressing head seat 4211 through a third spring 4213. The driving end of the pressing head 4212 swings under the combined action of the first driving mechanism 4300 and the third spring 4213, so as to control the other end of the pressing head 4212 relative to its driving end to press or release against the corresponding part of the pressing head seat 4211.

[0088] In some embodiments, a limiting groove 42114 extending in the first direction is further formed on the top surface of the pressing head seat 4211.

[0089] As an example, as Figure 9 、 Figure 10 and Figure 11 shown, an extension portion 42111 is formed at the top end of the pressing head seat 4211 along the first direction. A rotating shaft mounting hole 42112 extending in the second direction is formed on the extension portion 42111 for mounting a rotating shaft. One end of the pressing head 4212 is formed with a rotating shaft hole 42123, and the pressing head 4212 is passed through the rotating shaft through the rotating shaft hole 42123, so that the pressing head 4212 can swing around the rotating shaft. In addition, the upper surface of the end of the pressing head 4212 far from the rotating shaft hole 42123 is a driving surface 42122. The bottom of the driving surface 42122 is connected to the pressing head seat 4211 through a third spring 4213. Thus, the first driving mechanism 4300 squeezes the driving surface 42122 to realize the rotation of the pressing head 4212. When the first driving mechanism 4300 returns to its original position, the driving surface 42122 is reset under the action of the third spring 4213. A gland 42113 is also connected to the corresponding rotating shaft on the extension portion 42111. The gland 42113 is locked at the front end of the extension portion 42111 of the pressing head seat 4211 for limiting the axial movement of the rotating shaft in the rotating shaft mounting hole 42112.

[0090] And a limiting groove 42114 extending in the first direction (i.e., the transfer direction of the welding tape) is formed on the top surface of the pressing head seat 4211. When the pressing head 4212 and the pressing head seat 4211 cooperate to realize pressing, the special-shaped welding tape is limited in the limiting groove 42114 to prevent it from shifting during transfer.

[0091] In other embodiments, as Figure 12 shown, a plurality of strip-shaped grooves 42121 extending in the second direction are formed on one end of the pressing head 4212 relative to the lower side surface of the pressing head seat 4211.

[0092] That is to say, a plurality of strip grooves 42121 are arranged at intervals on the corresponding pressing surfaces of the indenter 4212, thereby forming a structure of a reticulated surface. Cooperating with the limit grooves 42114, it can further prevent the solder tape from slipping during the adjustment process and losing the position accuracy when clamping the solder tape.

[0093] In some embodiments, as Figure 7 and Figure 9 shown, the second driving mechanism 4400 may include: a guide rod motor 4410 and a guide shaft 4420. The guide rod motor 4410 is installed on the outer side of a vertical plate 4120. The guide rod of the guide rod motor 4410 passes through the vertical plate 4120 from the outside to the inside and is connected to the indenter seat 4211 to drive the indenter seat 4211 and the indenter 4212 to move in the first direction. The guide shaft 4420 is connected between a pair of vertical plates 4120 along the first direction, and the indenter seat 4211 is slidably connected to the guide shaft 4420.

[0094] Specifically, the second driving mechanism 4400 may include one or more guide rod motors 4410 and the guide shaft 4420. The guide shaft 4420 is used for limiting the movement of the indenter seat 4211 and the indenter 4212 between a pair of vertical plates 4120. The guide rod motor 4410 is installed on one of the vertical plates 4120 corresponding to the indenter seat 4211, and its guide rod passes through the vertical plate 4120 and is connected to the indenter seat 4211 to drive the indenter seat 4211 to move between a pair of vertical plates 4120, thereby realizing the adjustment of the node position of the solder tape pressed by the indenter seat 4211 and the indenter 4212. Among them, the guide rod motor 4410 is connected to the indenter seat 4211 through a guide rod adapter sleeve 4430. That is to say, by driving the indenter seat 4211 and the indenter 4212 to move through the guide rod motor 4410, the node position of the solder tape can be effectively and accurately adjusted.

[0095] In addition, a motor pressing plate 4440 is further connected to the vertical plate 4120 on which the guide rod motor 4410 is installed, and the guide rod motor 4410 is limited between the vertical plate 4120 and the motor pressing plate 4440 through the motor pressing plate 4440.

[0096] In some embodiments, the fourth mounting seat 4100 may further include at least one cylinder fixing plate 4130, and the cylinder fixing plate 4130 is arranged above a pair of vertical plates 4120. The first driving mechanism 300 may include at least one second driving cylinder 4310, and the second driving cylinder 4310 is arranged on the cylinder fixing plate 4130. The driving rod of the second driving cylinder 4310 passes through the cylinder fixing plate 4130 downward and abuts against the other end of the indenter 4212.

[0097] Specifically, a transfer seat 4140 is connected to each end of a pair of vertical plates 4120. A transfer block 4160 is pivotally connected to the transfer seat 4140. The transfer block 4160 can rotate in the vertical plane where the length direction of the vertical plate is located. One end of each of the two transfer seats 4140 is pivotally connected to the transfer seat 4140, and a cylinder fixing plate 4130 is detachably connected between the other ends of each. The cylinder fixing plate 4130 is correspondingly provided with a pressing mechanism 4200 above it. One or more second driving cylinders 4310 are installed on the cylinder fixing plate 4130. The driving rod of the second driving cylinder 4310 passes downward through the cylinder fixing plate 4130 to abut against the driving surface 42122 of the pressing head 4212, thereby realizing the pressing or loosening of the pressing mechanism 4200.

[0098] In some other embodiments, as Figure 7 and Figure 8 shown, the cylinder fixing plate 4130 can include two pieces, and the two cylinder fixing plates 4130 are arranged up and down on a pair of vertical plates 4120. The driving cylinders 4310 can include multiple ones, and the multiple second driving cylinders 4310 are arranged at intervals along the second direction on the upper and lower two cylinder fixing plates 4130. The driving rod of the upper-layer driving cylinder 4310 passes through the upper and lower two cylinder fixing plates 4130 in sequence to abut against the other end of the pressing head 4212, and the driving rod of the lower-layer driving cylinder 4310 passes through the lower-layer cylinder fixing plate 4130 to abut against the other end of the pressing head 4212.

[0099] Specifically, a connecting block 4150 can also be connected to the free end of the transfer block 4160. The upper and lower ends of the connecting block 4150 are respectively connected to the two cylinder fixing plates 4130. A plurality of second driving cylinders 4310 are respectively installed at intervals along the length direction on the two cylinder fixing plates 4130. The driving rod of the upper-layer driving cylinder 4310 passes through the upper-layer cylinder fixing plate 4130, the gap between the lower-layer driving cylinders 4310, and the lower-layer cylinder fixing plate 4130 in sequence to abut against the driving surface 42122 of the pressing head 4212, and the driving rod of the lower-layer driving cylinder 4310 passes downward through the lower-layer cylinder fixing plate 4130 to abut against the driving surface 42122 of the pressing head 4212. Thus, processing under the production demand of a larger number of solder tapes can be realized, and the production efficiency can be effectively improved.

[0100] In some embodiments, the transfer block 4160 can also be pin-connected to the transfer seat 4140. Thus, the overall components above the pressing mechanism 4200 can be rotated and opened around one end, which is convenient for disassembly and maintenance.

[0101] It should be noted here that the photovoltaic special-shaped solder tape node adjustment and cutting device of the present invention has a compact structure and can be applicable to the production requirements of components with 20 BB or more grid lines. Compared with traditional devices, it is applicable to the traction and cutting of more special-shaped solder tapes with a larger number and smaller size.

[0102] In addition, the photovoltaic special-shaped solder strip node adjustment and cutting device of the present invention can achieve independent adjustment of a single solder strip, independent straightening of both the triangular section and the flat section of the special-shaped solder strip, and flexible control of the straightening length of the special-shaped solder strip.

[0103] The node adjustment method of the present invention will be specifically described below.

[0104] As Figure 13 shown, it is a continuous special-shaped solder strip. The thin line segment part in the figure is the triangular section of the special-shaped solder strip, and the thick line segment part is the flat section of the special-shaped solder strip. Among them, point A is the pressing position of the second pressing and straightening module 320, point B is the pressing position of one of the first pressing and straightening modules 310, point C is the pressing position of the other first pressing and straightening module 310, point D is the cutting position of the special-shaped solder strip, point E is the clamping position of the moving adjustment module 400, point F is the recognition position of the visual recognition module 200, and G is the traction clamping position.

[0105] The specific adjustment is as follows:

[0106] 1) When the visual recognition module 200 recognizes that the solder strip node is within the normal range, point A is pressed, point E is pressed, point C is pressed, the solder strip is moved to the left for straightening, and the wire at point G is pulled to the right to pull out the solder strip for cutting.

[0107] 2) When the visual recognition module 200 recognizes that the solder strip node exceeds the normal range, point A is released, point C is released, point E is pressed and the solder strip with the corresponding node offset is adjusted. When the node is within the normal position range, the extra solder strip is cut off at point D, and points A, B, and C are pressed simultaneously. Points B and C move the solder strip to the left for straightening in different proportions according to the alignment position of the solder strip node.

[0108] 3) When preparing the solder strip for the string pitch, points A, B, C, and E are pressed simultaneously, and points B and C straighten the solder strip to the left in a certain proportion.

[0109] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and determined to cover all these other variations or modifications.
