Description

Technical Field

[0001] This utility model relates to the field of busbar feeding and sorting technology, specifically a busbar splicing and welding platform. Background Technology

[0002] Connecting the ends of solar cell strings together using busbars is a common method in photovoltaic module manufacturing. In the overlapping phase, the busbars need to be prepared and cut to the appropriate length to meet production requirements. Currently, busbars are slowly fed from a feed roll. When the first feed roll is empty, it needs to be replaced to feed another roll of busbars. Initially, the busbars needed to be re-threaded into the preparation and cutting equipment for preparation. However, to avoid time spent threading, the ends of the first roll of busbars and the beginnings of the second roll are manually welded together. When the traction gripper pulls the end of the first roll of busbars, because the busbar is already welded to the next roll, it will carry the beginning of the second roll of busbars along with it, thus completing the feeding process without needing to re-thread. However, manually welding the overlaps next to the feed rolls takes a long time, and if the weld is not completely secure, it may break open at the overlap during subsequent feeding, requiring re-threading and affecting feeding efficiency. Summary of the Invention

[0003] To address the problems in the existing technology, the purpose of this utility model is to provide a busbar splicing and welding platform. Adding a busbar splicing and welding platform before the sorting section can avoid manual splicing of busbars, ensure splicing speed and welding effect, and improve the efficiency of material change splicing.

[0004] The busbar splicing and welding platform includes a guide device, a welding device, and a cutting device arranged sequentially according to the busbar transportation direction. The guide device is located at the front end of the welding device, and the cutting device is located at the rear end of the welding device.

[0005] By setting a guiding device, the busbar is guided into the welding device, and the tail of the previous busbar is welded together in the welding device. Then, the busbar is cut to a fixed length or the welding position of the busbar is removed by the cutting device. By setting a busbar splicing and welding platform at the position of the busbar during the feeding process, the lap welding of the busbar head and tail is realized automatically, avoiding manual lap welding of the busbar and ensuring the lap speed and welding effect.

[0006] Specifically, a first fixing gripper is provided between the guiding device and the welding device.

[0007] The first fixed gripper allows the new busbar to be fixed in position during welding and clamping.

[0008] Specifically, a second fixed gripper is provided between the welding device and the cutting device.

[0009] The second fixing claw allows the old busbar to be fixed in position during welding and clamping.

[0010] Furthermore, the welding device includes a welding head and a welding backing plate, and the welding backing plate is provided with a busbar guide groove for both the guiding device and the cutting device.

[0011] The busbar guide groove ensures that both new and old busbars are guided and restrained when being transported to the welding pad, enabling the two busbars to be precisely and quickly aligned, thus improving welding quality and speed.

[0012] Preferably, the welding pad also includes a synthetic stone slab disposed in the middle of the busbar guide groove.

[0013] Specifically, the manifold guide channel is formed by two baffles, a left baffle and a right baffle, surrounding the synthetic slab.

[0014] Preferably, the welding pad also includes a buffer seat, on which the synthetic stone slab is elastically mounted.

[0015] By using a buffer seat, the welding head is prevented from impacting the welding pad when it descends for welding. The buffer seat elastically presses the busbar against the welding head for welding, which on the one hand prevents the welding head from being damaged by impact, and on the other hand ensures the welding quality by elastically pressing the welding head.

[0016] Specifically, the welding head is mounted on a lifting power device, which is configured to move the welding head closer to or away from the welding pad.

[0017] In summary, by setting up a guiding device to guide the busbar into the welding device, the tail of the previous busbar roll is welded together in the welding device. Then, a cutting device cuts the busbar to a fixed length or removes the welding position. By setting up a busbar splicing and welding platform at the location of the busbar loading process, the lap welding of the busbar ends is automatically realized, avoiding manual lap welding of the busbar and ensuring lap speed and welding effect. The setting of the first fixed jaw allows the new busbar to be fixed in position during welding and clamping. The setting of the second fixed jaw allows the old busbar to be fixed in position during welding and clamping. The busbar guide groove ensures that both the new and old busbars are guided and restrained when they are transported to the welding pad, so that the two busbars can be accurately and quickly aligned, improving welding quality and welding speed. By using a buffer seat, the welding head is prevented from impacting the welding pad when it descends for welding. The buffer seat elastically presses the busbar against the welding head for welding, which on the one hand prevents the welding head from being damaged by impact, and on the other hand ensures the welding quality by elastically pressing the welding head.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1As shown, the busbar splicing and welding platform includes a guide device 1, a welding device 2, and a cutting device 3 arranged sequentially according to the busbar transport direction. The guide device 1 is located at the front end of the welding device 2, and the cutting device 3 is located at the rear end of the welding device 2. The guide device 1 guides the busbar into the welding device 2, where it is welded to the tail of the previous roll of busbar. Then, the cutting device 3 cuts the busbar to a fixed length or removes the welding section. By setting up a busbar splicing and welding platform at the location of the busbar during the loading process, the automatic lap welding of the busbar's beginning and end is achieved, avoiding manual lap welding and ensuring lap speed and welding effect.

[0027] like Figure 2 As shown, a first fixing jaw 4 is provided between the guide device 1 and the welding device 2; a second fixing jaw 5 is provided between the welding device 2 and the cutting device 3. The first fixing jaw 4 allows the new busbar to be fixed in position during welding and clamping. The second fixing jaw 5 allows the old busbar to be fixed in position during welding and clamping. In this structure, the first fixing jaw 4 and the second fixing jaw 5 are commonly used finger cylinders.

[0028] like Figures 3 to 6 As shown, the welding device 2 includes a welding head W and a welding pad. The welding pad is equipped with a busbar guide groove T corresponding to both the guiding device 1 and the cutting device 3. The busbar guide groove T ensures that both new and old busbars are guided and restricted when they are transported to the welding pad, enabling the two busbars to be precisely and quickly aligned, thus improving welding quality and speed.

[0029] To ensure welding quality, the welding backing plate also includes a synthetic stone plate 8 set in the middle of the busbar guide groove T, such as... Figure 3 As shown in the diagram, the high hardness and low thermal conductivity of the synthetic stone slab 8 ensure the stability of the lap welding, which is far superior to the spot welding method using a soldering iron.

[0030] Specifically, such as Figure 4 As shown, the busbar guide channel T is formed by two baffles, a left baffle 6 and a right baffle 7, surrounding the synthetic slab 8; a channel of the width of the busbar is formed between the ends of the left baffle 6 and the right baffle 7, allowing the busbar to be confined within the busbar guide channel T for transport, as shown. Figure 4 As shown, the distance between the left baffle 6 and the right baffle 7 can also be adjusted by the edge perforated plate to accommodate the compatibility requirements of busbars of different widths, thus improving the adaptability of the overall structure.

[0031] When the lifting power device 10 drives the welding head downwards, if the welding pad is just a rigid plate, the impact of the welding head on the welding pad will be a hard contact, and the welding head W will be damaged after only a few uses. At the same time, the clamping force during busbar welding cannot be guaranteed. Therefore, to solve the above problems, the welding pad also includes a buffer seat 9. The synthetic stone plate 8 is elastically mounted on the buffer seat 9. The buffer seat 9 prevents the welding head W from hard impacting the welding pad when it descends for welding. The buffer seat 9 elastically presses the busbar against the welding head W for welding, thus preventing damage to the welding head W from impact and ensuring welding quality through elastic clamping. In this embodiment, the buffer seat 9 can be configured to have the synthetic stone plate 8 mounted on one end of the elastic guide rod. Each time the lifting power device 10 presses down on the synthetic stone plate 8, it continues to move downwards, pressing the synthetic stone plate 8 and compressing the elastic guide rod. The elastic reverse force and the downward-moving welding head form a corresponding clamping force, thereby clamping the ends of the two busbars for welding.

[0032] In order to enable the welding head W to rise and fall, the welding head W is mounted on the lifting power device 10, such as... Figure 6 As shown, the lifting power device 10 is configured to move the welding head W closer to or away from the welding pad. In this embodiment, the lifting power device 10 is a lifting cylinder. The welding head W can be an electromagnetic welding head or a resistance welding head, etc. The welding head W can be slidably connected to the mounting back plate through a slide rail slider. The lifting cylinder is installed on the mounting back plate, and the piston rod of the lifting cylinder is fixedly connected to the welding head W.
