Description

Technical Field

[0001] The present application relates to the technical field of battery ribbon processing equipment, and in particular to a ribbon cutting device. Background Art

[0002] During the production of photovoltaic cell string modules, the soldering ribbon is first pulled onto the ribbon cutting device, where a holding assembly holds the ribbon.

[0030] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0031] See Figure 1 A welding ribbon cutting device provided in one embodiment of the present application includes a first bracket 10, a second bracket 11, a segmented cutting mechanism 21, a fixed-length cutting mechanism 20, a head pressing mechanism 30 and a tail pressing mechanism 40.

[0032] In one embodiment, see Figure 1 and Figure 2 Two first brackets 10 are provided, and the two first brackets 10 are spaced apart along the first direction, with X being used to represent the first direction. At least two second brackets 11 are provided, and all second brackets 11 are located between the two first brackets 10 along the first direction. The first bracket 10 and the second bracket 11 are each provided with a first placement portion 121 and a second placement portion 131 for placing the solder ribbon. There are at least two first placement portions 121 and at least two second placement portions 131, and all first placement portions 121 and second placement portions 131 are spaced apart along the second direction, wherein the first direction intersects the second direction, with Y being used to represent the second direction, and all first placement portions 121 correspond one-to-one with all second placement portions 131 along the first direction.

[0033] Optionally, the first placement portion 121 is provided with a first placement groove, and the second placement portion 131 is provided with a second placement groove. During operation, the soldering ribbon is placed in the first placement groove and the second placement groove along the first direction. The first placement groove and the second placement groove can limit the soldering ribbon and prevent the soldering ribbon from shifting.

[0034] In one embodiment, see Figure 1 The fixed length cutting mechanism 20 is installed on the first bracket 10 at the rear end. Figure 2 For example, the first bracket 10 at the tail is the rightmost bracket, and the fixed-length cutting mechanism 20 is used to cut the tail of the solder strip to a fixed length. At least two segmented cutting mechanisms 21 are provided, and all segmented cutting mechanisms 21 are installed in a one-to-one correspondence on the second bracket 11. The segmented cutting mechanisms 21 are located between the first placement portion 121 and the second placement portion 131. One of the odd-numbered and even-numbered segmented cutting mechanisms 21 is used to segmentally cut odd-numbered solder strips, and the other is used to segmentally cut even-numbered solder strips. Both the first bracket 10 and the second bracket 11 are equipped with a head clamping mechanism 30 and a tail clamping mechanism 40. The head clamping mechanism 30 is used to clamp all solder strips located in the first placement portion 121, and the tail clamping mechanism 40 is used to clamp all solder strips located in the second placement portion 131.

[0035] After the soldering ribbon is placed on the first bracket 10 and the second bracket 11, the head clamping mechanism 30 is activated to clamp the soldering ribbon located on the first placement portion 121, while the tail clamping mechanism 40 is activated to clamp the soldering ribbon located on the second placement portion 131. Then, the fixed-length cutting mechanism 20 is activated to cut the tails of all the soldering ribbons to achieve a fixed length. After the fixed-length cutting is completed, the segmented cutting mechanism 21 is activated to cut the soldering ribbon into segments based on the parity of the soldering ribbon. Before the soldering ribbon is transported to the welding platform, the head clamping mechanism 30 and the tail clamping mechanism 40 continuously clamp the soldering ribbon. For example, after the segmented cutting is completed, one end of each soldering ribbon segment along the first direction is clamped by the head clamping mechanism 30, and the other end of each soldering ribbon segment along the first direction is clamped by the tail clamping mechanism 40. This can prevent soldering ribbon deviation and poor solder joints caused by twisting and arching of the soldering ribbon, thereby ensuring the production quality of the battery.

[0036] In one embodiment, see Figure 3 The first bracket 10 and the second bracket 11 each include a first frame 12 and a second frame 13. The first frame 12 and the second frame 13 are spaced apart along the first direction, and the first frame 12 and the second frame 13 are both extended along the second direction.

[0037] Further, see Figure 3 The first placement portion 121 and the head pressing mechanism 30 are disposed on the first frame 12 , and the second placement portion 131 and the tail pressing mechanism 40 are disposed on the second frame 13 .

[0038] Optionally, see Figure 3 The first placement portion 121 is located on the side of the first frame 12 facing away from the second frame 13, and the head pressing mechanism 30 is located on the side of the first frame 12 facing the second frame 13. The second placement portion 131 is located on the side of the second frame 13 facing away from the first frame 12, and the tail pressing mechanism 40 is located on the side of the second frame 13 facing the first frame 12.

[0039] In one embodiment, see Figure 5 and Figure 6 The head pressing mechanism 30 includes a first pressing member 31 and a first driving member 32. Figure 3A first receiving groove 122 is provided on the side of the first frame 12 facing the second frame 13, and a first pressing member 31 is disposed in the first receiving groove 122. The first pressing member 31 has at least two first pressing portions 311, all of which are spaced apart along the second direction. A first driving member 32 is connected to the first pressing member 31 and is used to drive the first pressing member 31 to move, causing the first pressing portions 311 to compress or release the soldering ribbon located on the first placement portion 121. After the soldering ribbon is placed on the first bracket 10 and the second bracket 11, the first driving member 32 is actuated to drive the first pressing member 31 downward, so that all of the first pressing portions 311 are pressed against all of the soldering ribbons in a one-to-one correspondence. Furthermore, the first driving member 32 can reverse, driving the first pressing member 31 upward, separating the first pressing portions 311 from the soldering ribbon. This allows the cut soldering ribbon to be transported to the welding platform for welding. In this way, automatic compression and release of the soldering ribbon can be achieved.

[0040] Optionally, the first driving member 32 is a cylinder, which is vertically fixed to the second bracket 11. Of course, in other embodiments, the first driving member 32 can also be an electric cylinder, a hydraulic cylinder, a screw module, etc., without limitation thereto.

[0041] In one embodiment, see Figure 5 Before the head pressing mechanism 30 is activated, all the first pressing portions 311 are staggered with all the first placement portions 121. This arrangement prevents the soldering ribbon from interfering with the first pressing portions 311 during placement of the soldering ribbon on the first bracket 10 and the second bracket 11.

[0042] In one embodiment, see Figure 5 and Figure 6 The first frame 12 is provided with a first strip hole 123 , which is tilted relative to the second direction. The first pressing member 31 is provided with a first connecting shaft 312 , which is movably provided in the first strip hole 123 .

[0043] Further, see Figure 5 and Figure 6 The first pressing member 31 is provided with a second strip-shaped hole 313, which is arranged along the second direction. The first driving member 32 is provided with a second connecting shaft 321, which is movably disposed in the second strip-shaped hole 313. Driven by the first driving member 32, all the first pressing portions 311 can be pressed downward at an angle and arranged one by one opposite to all the first placement portions 121.

[0044] See Figure 5 and Figure 6During the solder ribbon compression process, the first driving member 32 drives the first pressing member 31 downward. At this time, the first connecting shaft 312 moves downward along the wall of the first strip-shaped hole 123. Simultaneously, the second strip-shaped hole 313 provides space for the first pressing member 31 to move in the second direction, ensuring that the first pressing portion 311 can press down diagonally. After the first pressing portion 311 is pressed down diagonally, all first pressing portions 311 are aligned with all first placement portions 121, compressing all solder ribbons located in the first placement portions 121.

[0045] In one embodiment, see Figure 5 At least two first strip-shaped holes 123 are provided, and all first strip-shaped holes 123 are spaced apart along the second direction. At least two first connecting shafts 312 are provided, and all first connecting shafts 312 are disposed in a one-to-one correspondence within all first strip-shaped holes 123. This improves the stability of the movement of the first pressing member 31.

[0046] In this embodiment, there are two first strip-shaped holes 123 , which are spaced apart along the second direction. Two first connecting shafts 312 are provided, which are disposed in the two first strip-shaped holes 123 in a one-to-one correspondence.

[0047] In one embodiment, see Figure 4 , the tail clamping mechanism 40 includes a second clamping member 41 and a second driving member 42. Specifically, a second accommodating groove 132 is provided on the side of the second frame 13 facing the first frame 12, and the second clamping member 41 is arranged in the second accommodating groove 132. The second clamping member 41 is provided with at least two second clamping parts 411, and all the second clamping parts 411 are arranged at intervals along the second direction. The second driving member 42 is connected to the second clamping member 41, and the second driving member 42 is used to drive the second clamping member 41 to move so that the second clamping part 411 clamps or releases the welding strip located on the second placement part 131. After the welding strip is placed on the first bracket 10 and the second bracket 11, the second driving member 42 is actuated to drive the second clamping member 41 to press down, so that all the second clamping parts 411 are pressed on all the welding strips one by one. Furthermore, the second driving member 42 can move in the reverse direction to drive the second pressing member 41 to lift up, so that the second pressing portion 411 is separated from the welding ribbon, so that the segmented welding ribbon can be transported to the welding platform for welding. In this way, the welding ribbon can be automatically compressed and released.

[0048] Optionally, the second driving member 42 is a cylinder, which is vertically fixed to the second bracket 11. Of course, in other embodiments, the second driving member 42 can also be an electric cylinder, a hydraulic cylinder, a screw module, etc., without limitation thereto.

[0049] In one embodiment, before the tail pressing mechanism 40 is activated, all second pressing portions 411 are staggered with all second placement portions 131. This prevents interference between the soldering ribbon and the second pressing portions 411 during placement of the soldering ribbon on the first bracket 10 and the second bracket 11.

[0050] Further, see Figure 4 The second frame 13 is provided with a third strip hole 133 , which is tilted relative to the second direction. The second pressing member 41 is provided with a third connecting shaft 412 , which is movably provided in the third strip hole 133 .

[0051] Further, see Figure 4 The second pressing member 41 is provided with a fourth strip-shaped hole 413, which is arranged along the second direction. The second driving member 42 is provided with a fourth connecting shaft 421, which is movably disposed in the fourth strip-shaped hole 413. Driven by the second driving member 42, all the second pressing portions 411 can be pressed downward at an angle and arranged one by one opposite to all the second placement portions 131.

[0052] See Figure 5 and Figure 6 During the solder ribbon compression process, the second driving member 42 drives the second compression member 41 downward. At this time, the third connecting shaft 412 moves downward along the wall of the third strip-shaped hole 133. Simultaneously, the fourth strip-shaped hole 413 provides clearance for the second compression member 41 to move in the second direction, ensuring that the second compression portion 411 can press down diagonally. After the second compression portion 411 is pressed down diagonally, all second compression portions 411 are aligned with all second placement portions 131, compressing all solder ribbons located in the second placement portions 131.

[0053] In one embodiment, see Figure 4 At least two third strip-shaped holes 133 are provided, and all third strip-shaped holes 133 are spaced apart along the second direction. At least two third connecting shafts 412 are provided, and all third connecting shafts 412 are disposed in a one-to-one correspondence within all third strip-shaped holes 133. This improves the stability of the movement of the second pressing member 41.

[0054] In this embodiment, there are two third strip holes 133 , which are spaced apart along the second direction. Two third connecting shafts 412 are provided, which are disposed in the two third strip holes 133 in a one-to-one correspondence.

[0055] In one embodiment, see Figure 7 、 Figure 8 and Figure 9The segmented cutting mechanism 21 and the fixed-length cutting mechanism 20 both include a cutting piece 22 and a third driving piece 23. The cutting piece 22 is provided with at least two cutting portions 221, and all the cutting portions 221 are spaced apart along the second direction. The third driving piece 23 is connected to the cutting piece 22, and the third driving piece 23 is used to drive the cutting piece 22 to move so that the cutting portion 221 cuts the welding strip. After the head pressing mechanism 30 and the tail pressing mechanism 40 press the welding strip, the third driving piece 23 of the fixed-length cutting mechanism 20 is actuated to drive the corresponding cutting piece 22 to cut the tail of all welding strips to achieve a fixed length of the welding strip. After the fixed-length cutting is completed, the third driving piece 23 of the segmented cutting mechanism 21 is actuated to drive the corresponding cutting piece 22 to segmentally cut the welding strip according to the parity of the welding strip.

[0056] It should be noted that the cutter portion 221 of the odd-numbered segmented cutting mechanism 21 is staggered with the cutter portion 221 of the even-numbered segmented cutting mechanism 21, so that one of the odd-numbered and even-numbered cutting mechanisms is used to cut the odd-numbered welding strips, and the other is used to cut the even-numbered welding strips.

[0057] Optionally, the third driving member 23 is a cylinder, and the cylinder is fixed to the first bracket 10 along the second direction. Of course, in other embodiments, the third driving member 23 can also be a screw module, etc., and is not limited thereto.

[0058] In one embodiment, see Figure 2 and Figure 7 The second bracket 11 and the first bracket 10 at the rear further include a third bracket body 14 .

[0059] Further, see Figure 7 In the first bracket 10 at the rear, the third frame 14 is provided on the side of the second frame 13 away from the first frame 12 , and the fixed-length cutting mechanism 20 is installed on the third frame 14 of the first bracket 10 at the rear.

[0060] Further, see Figure 2 In the second bracket 11 , the third bracket 14 is disposed between the first bracket 12 and the second bracket 13 , and the segmented cutting mechanism 21 is mounted on the third bracket 14 of the second bracket 11 .

[0061] In one embodiment, see Figure 7 、 Figure 8 and Figure 9 The third frame 14 has a fifth strip hole 141 , which is tilted relative to the second direction. The cutting piece 22 has a fifth connecting shaft 2212 movably disposed in the fifth strip hole 141 .

[0062] Furthermore, the cutting member 22 is provided with a sixth strip-shaped hole 2211, which is arranged in a vertical direction. The power shaft of the third driving member 23 is provided with a sixth connecting shaft 231, which is movably disposed within the sixth strip-shaped hole 2211. Driven by the third driving member 23, the cutting member 22 can move diagonally downward, so that the cutting portion 221 cuts the welding strip at an angle.

[0063] During the segmented cutting operation, the power shaft of the third driving member 23 extends along the second direction, so that the fifth connecting shaft 2212 moves obliquely downward along the hole wall of the fifth strip hole 141. At this time, the sixth strip hole 2211 provides an avoidance space for the movement of the cutting member 22 along the second direction, ensuring that the cutting member 22 can move obliquely downward. In this way, the cutting portion 221 cuts the welding strip obliquely downward, which can reduce the phenomenon of burrs after the welding strip is segmented cut, and avoid the burrs piercing the battery insulating glue and causing a short circuit.

[0064] In one embodiment, see Figure 1 The solder ribbon cutting device also includes a distance-changing mechanism 50. The distance-changing mechanism 50 is connected to the first bracket 10 and the second bracket 11. The distance-changing mechanism 50 is used to drive the first bracket 10 and the second bracket 11 to move in a first direction to adjust the spacing between adjacent solder ribbons after the segmented cutting. This allows the spacing between adjacent solder ribbons to be adjusted according to different layouts, making it suitable for welding multiple layouts with different battery specifications. The segmented cutting process eliminates the generation of solder ribbon fragments, which prevents the soldering mechanism from being affected during welding, thereby improving welding efficiency and reducing the cost of the solder ribbon.

[0065] In one embodiment, see Figure 1 The welding ribbon cutting device further includes a base 60. The pitch changing mechanism 50 is mounted on the base 60, and the base 60 provides an installation position for the pitch changing mechanism 50 and the like.

[0066] Further, see Figure 1 The pitch-changing mechanism 50 includes a fourth drive member 51, a first transmission wheel, a second transmission wheel 53, and a transmission belt 54. The fourth drive member 51 is mounted on the base 60 and is drivingly connected to the first transmission wheel. Optionally, the fourth drive member 51 is a motor. The first transmission wheel and the second transmission wheel 53 are spaced apart along the first direction, and the transmission belt 54 passes around the first transmission wheel and the second transmission wheel 53. The transmission belt 54 is connected to the first bracket 10 and the second bracket 11. In this way, during the operation of the transmission belt 54, the transmission belt 54 drives the two brackets connected thereto to move evenly to both sides, achieving uniform pitch change.

[0067] If the number of second brackets 11 is N, and N is an even number, then there are (N+2) / 2 pitch-changing mechanisms 50, all spaced apart along the second direction. The two first brackets 10 are connected to the same transmission belt 54 on either side of the first direction. The first second bracket 11 and the Nth second bracket 11 are connected to the same transmission belt 54 on either side of the first direction. The second second bracket 11 and the N-1th second bracket 11 are connected to the same transmission belt 54 on either side of the first direction. This pattern continues until the N / 2th second bracket 11 and the (N / 2)+1th second bracket 11 are connected to the same transmission belt 54 on either side. The first bracket 10 at the top and the first to N / 2th second brackets 11 move in the same direction. The (N / 2)+1th second bracket 11 and the last first bracket 10 move in the same direction.

[0068] If the number of second brackets 11 is N, and N is an odd number, then there are (N+1) / 2 pitch-changing mechanisms 50, all spaced apart along the second direction. The (N+1) / 2th second bracket 11 is fixed to the base 60. The two first brackets 10 are connected to the same transmission belt 54 on either side in the first direction. The first second bracket 11 and the Nth second bracket 11 are connected to the same transmission belt 54 on either side. The second second bracket 11 and the N-1th second bracket 11 are connected to the same transmission belt 54 on either side. This pattern continues until the two second brackets 11 adjacent to the (N+1) / 2th second bracket 11 are connected to the same transmission belt 54 on either side. The first bracket 10 at the beginning and the second brackets 1 through [(N+1) / 2]-1th second brackets 11 move in the same direction. The second bracket 11 from [(N+1) / 2]+1th second bracket 11 to the last bracket 10 move in the same direction.

[0069] Optionally, the first bracket 10 and the second bracket 11 are connected to the transmission belt 54 via buckles.

[0070] In one embodiment, see Figure 2 The base 60 is provided with a guide portion 61, and the guide portion 61 is arranged along the first direction. Optionally, the guide portion 61 is a guide rail.

[0071] Further, see Figure 2 The first bracket 10 and the second bracket 11 are each provided with a sliding portion 62 that slidably cooperates with the guide portion 61. Optionally, the sliding portion 62 is a slider. Thus, when the pitch-changing mechanism 50 drives the first bracket 10 and the second bracket 11 to move in the first direction, the guide portion 61 cooperates with the sliding portion 62 to provide guidance for the movement of the first bracket 10 and the second bracket 11 in the first direction, thereby ensuring stability and accuracy in pitch change.
