Description

Technical Field

[0001] The utility model relates to the technical field of solar cell welding, in particular to a discharging device for preventing welding tape from winding. Background Technique

[0002] Due to the stencil characteristics of traditional solar cells, multiple traditional solar cells and multiple welding tapes need to be welded into a battery string. During the process, the welding tape for the series welding of solar cells needs to be unrolled, and usually, a stepping motor is used to control the unrolling length of the welding tape.

[0003] For example, a Chinese patent application with the application number 202220821611.2 and the publication date of August 6, 2022, discloses an unrolling system for series welding of solar cells, which includes an unrolling mechanism and a tensioning mechanism. A tensioning mechanism is arranged on the discharging side of the unrolling mechanism; the unrolling mechanism includes an unrolling shaft for series welding of solar cells, and a welding tape inductor is additionally arranged on the unrolling shaft for series welding of solar cells; the tensioning mechanism includes a welding tape transition wheel and a counterweight wheel; the counterweight wheel includes an upper counterweight wheel and a lower counterweight wheel, and the upper counterweight wheel and the lower counterweight wheel are arranged in a vertically staggered manner; the welding tape passes through the welding tape transition wheel, the upper counterweight wheel and the lower counterweight wheel in sequence and then discharges.

[0004] The above-mentioned document drives the welding tape to unroll through a motor, and then supports the welding tape through a support wheel arranged in the horizontal direction to make the welding tape transition to the tensioning mechanism. However, it does not specifically describe the specific placement position of the unrolling shaft for series welding of solar cells. If multiple unrolling shafts for series welding of solar cells are arranged in a parallel matrix, when multiple unrolling shafts for series welding of solar cells unroll simultaneously, the welding tapes on multiple unrolling shafts for series welding of solar cells will affect each other during the unrolling process because the paths they pass through are parallel, resulting in winding. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a discharging device for preventing welding tape from winding, which can avoid the winding of the welding tape during the unrolling process, so as to ensure that the welding tape can be normally unrolled and series welded with solar cells.

[0006] To achieve the above object, a discharging device for preventing solder tape winding includes a hanging plate, a supporting wheel assembly, a tensioning wheel assembly, and more than two discharging groups. An discharging area is provided on the hanging plate. The adjacent discharging groups are arranged in parallel in the discharging area. Each discharging group includes more than two solder tape unwinding assemblies. Each solder tape unwinding assembly includes a guiding wheel assembly and a coil assembly. The guiding wheel assembly is arranged at the lower left side of the coil assembly. The guiding wheel assembly includes guiding wheels. The coil assembly includes coils. In a vertical plane parallel to the hanging plate, the straight line passing through the centers of all guiding wheels in the same discharging group is parallel to the straight line passing through the centers of all coils. The straight line passing through the centers of all guiding wheels in the same discharging group is inclined downward in a horizontal direction of the hanging plate. The coils in the adjacent discharging groups are on the same vertical line. The vertical line is inclined inward with respect to the straight line passing through the centers of the guiding wheels corresponding to the coils on the same vertical line in the adjacent two discharging groups.

[0007] With the above structure, the discharging group can be inclined with respect to the horizontal line, which is convenient for the solder tape to be more easily wound out from the coil assembly. And since the straight line where the centers of the guiding wheels in the adjacent two discharging groups are located is inclined with respect to the vertical line of the hanging plate, the solder tapes in the two discharging groups adjacent in the up and down direction can slide out from the guiding wheels at different positions, so that the discharging directions of the solder tapes can be different. And the direction of the solder tape wound out can be adjusted through the guiding wheel assembly, so that the winding directions of the solder tapes in the adjacent discharging groups are different, thus effectively preventing the solder tape from being wound during the process of being wound out to the supporting wheel assembly.

[0008] Further, the angle formed by the straight line passing through the centers of all guiding wheels in the same discharging group and the horizontal line passing through the centers of the guiding wheels is 5° - 10°.

[0009] The above setting makes the centers of the guiding wheels inclined downward at a certain angle with respect to the horizontal line, and does not affect the overall solder tape unwinding effect.

[0010] Further, the angle formed by the vertical line and the straight line passing through the centers of the guiding wheels corresponding to the coils on the same vertical line in the adjacent two discharging groups is 5° - 10°.

[0011] The above setting makes the vertical line inclined outward at a small angle with respect to the centers of the guiding wheels corresponding to the adjacent coils, which can prevent winding while ensuring that the guiding wheel assembly has a certain guiding effect.

[0012] Further, there are more than two supporting wheel assemblies. The more than two supporting wheel assemblies are on the same straight line to form a solder tape support area. The supporting wheel assemblies are arranged below the discharging area. Each supporting wheel assembly includes a mounting seat one, a fixing shaft one, and a supporting wheel. The mounting seat one is fixedly arranged on one side of the hanging plate. One end of the fixing shaft one is fixed on the mounting seat one, and the other end of the fixing shaft one extends vertically outward from the hanging plate to form a free end. The supporting wheel is sleeved on the fixing shaft one.

[0013] The above settings facilitate the solder tape wound out from the solder tape unwinding assembly to pass through the support wheel, which plays a guiding role for the solder tape, changes the direction of the solder tape, and enables the solder tape to enter the next process through the support wheel.

[0014] Further, two or more solder tape grooves matching the solder tape are provided on the support wheel.

[0015] The above settings prevent the solder tapes wound out from different solder tape unwinding assemblies from getting entangled when passing through the same support wheel.

[0016] Further, a fixing plate is provided on one side of the hanging plate. The fixing plate is arranged on one side of the solder tape support area. Two or more tensioning wheel assemblies are provided on the fixing plate. The tensioning wheel assemblies are arranged along the length direction of the fixing plate. Each tensioning wheel assembly includes a second mounting seat, a second fixed shaft, and a tensioning wheel. The second mounting seat is fixedly arranged on the fixing plate. One end of the second fixed shaft is fixed on the second mounting seat, and the other end of the second fixed shaft extends perpendicularly outward from the fixing plate to form a free end. The tensioning wheel is sleeved on the second fixed shaft.

[0017] The above settings facilitate the solder tape to be tensioned by the tensioning wheel assemblies on the fixing plate after changing the direction through the solder tape support area, preventing the solder tape from becoming slack.

[0018] Further, two or more receiving grooves matching the solder tape are provided on the tensioning wheel.

[0019] The above settings prevent the solder tapes wound out from different support wheel assemblies from getting entangled when passing through the same tensioning wheel.

[0020] Further, the guiding wheel assembly further includes a third mounting seat, a third fixed shaft, and two first limiting blocks. The third mounting seat is fixed on one side of the hanging plate. One end of the third fixed shaft is fixed on the third mounting seat, and the other end of the third fixed shaft extends perpendicularly outward from the hanging plate to form a free end. The guiding wheel is sleeved on the third fixed shaft, and the two first limiting blocks are respectively sleeved on both ends of the guiding wheel.

[0021] The above settings facilitate the solder tape to adjust the direction of the solder tape wound out from the coil assembly through the guiding wheel, so that it can be wound around the support wheel without getting entangled with the solder tapes of adjacent coil assemblies. At the same time, the first limiting blocks can limit the movement of the guiding wheel in the axial direction of the third fixed shaft.

[0022] Further, the coil assembly further includes a driving device, a fourth fixed shaft, and two second limiting blocks. The driving device is fixed on the other side of the hanging plate. One end of the fourth fixed shaft is fixedly connected with the driving device, and the other end of the fourth fixed shaft extends perpendicularly outward from the hanging plate to form a free end. The coil is sleeved on the fourth fixed shaft, and the two second limiting blocks are respectively sleeved on both ends of the coil.

[0023] The above settings facilitate the driving device to drive the material roll to rotate, enabling the welding tape to unwind from the material roll, and the second limiting block can restrict the movement of the material roll in the axial direction of the fourth fixed shaft.

[0024] Further, the driving device includes a driving motor and a motor mounting seat. The motor mounting seat is fixed on the other side of the hanging plate, the driving motor is fixed on the motor mounting seat, and the output end of the driving motor is fixedly connected to the fourth fixed shaft.

[0025] The above settings can drive the fourth fixed shaft to rotate through the driving motor, and then drive the welding tape to unwind from the material roll. Description of the Drawings

[0031] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0032] As Figures 1 to 5 shown, a discharging device for preventing the welding tape from winding includes a hanging plate 1, a support wheel assembly, a tensioning wheel assembly, and two or more discharging groups 2. There are two hanging plates 1, and a discharging area 3 is provided on the hanging plates 1. The adjacent two discharging groups 2 are arranged in parallel in the discharging area 3. The discharging group 2 includes two or more welding tape unwinding assemblies. In this embodiment, as Figure 2 shown, three discharging groups 2 are provided in the discharging area 3, and four welding tape unwinding assemblies are provided in each discharging group 2. The welding tape unwinding assembly includes a guide wheel assembly 5 and a material roll assembly 6. The guide wheel assembly 5 is arranged on the lower left side of the material roll assembly 6, as Figure 3As shown, the guide wheel assembly 5 includes a guide wheel 51, a third mounting seat 52, a third fixed shaft 53, and two first limit blocks 54. The third mounting seat 52 is fixed to one side of the hanging plate 1. One end of the third fixed shaft 53 is fixed to the third mounting seat 52, and the other end of the third fixed shaft 53 extends outward perpendicular to the hanging plate 1 to form a free end. The guide wheel 51 is sleeved on the third fixed shaft 53, and the two first limit blocks 54 are respectively sleeved on both ends of the guide wheel 51, so as to facilitate the solder tape to adjust the direction of the solder tape wound out from the reel assembly 6 through the guide wheel 51, so that it can be wound around the support wheel and not be wound with the solder tape of the adjacent reel assembly 6. At the same time, the first limit block 54 can limit the movement of the guide wheel 51 in the axial direction of the third fixed shaft 53.

[0033] As Figure 1 and 3 shown, the reel assembly 6 includes a reel 61, a driving device, a fourth fixed shaft 62, and two second limit blocks 63. The driving device is fixed to the other side of the hanging plate 1. The driving device includes a driving motor 64 and a motor mounting seat 65. The motor mounting seat 65 is fixed to the other side of the hanging plate 1, and the driving motor 64 is fixed to the motor mounting seat 65. The output end of the driving motor 64 is fixedly connected to one end of the fourth fixed shaft 62. The other end of the fourth fixed shaft 62 extends outward perpendicular to the hanging plate 1 to form a free end. The reel 61 is sleeved on the fourth fixed shaft 62. A solder tape monitor 66 is provided above the reel 61, which can monitor whether there is solder tape on the reel 61. In this way, when there is no solder tape on the reel 61, it can be replaced in time. The two second limit blocks 63 are respectively sleeved on both ends of the reel 61, so as to facilitate the driving device to drive the reel 61 to rotate, so that the solder tape is wound out from the reel 61, and the second limit block 63 can limit the movement of the reel in the axial direction of the fourth fixed shaft 62.

[0034] As Figure 2As shown in the figure, in the vertical plane parallel to the hanging plate 1, the straight line L1 passing through the centers of all the guide wheels 51 in the same discharging group 2 is parallel to the straight line L2 passing through the centers of all the strip coils 61. The straight line L1 passing through the centers of all the guide wheels 51 in the same discharging group 2 and the horizontal line L3 passing through the centers of the guide wheels 51 are inclined downward. In this embodiment, the angle formed by the straight line L1 and the horizontal line L3 is a, and the value range of a is 5° to 10°. The strip coils 61 in the adjacent discharging groups 2 are on the same vertical line L4. The vertical line L4 and the straight line L5 passing through the centers of the guide wheels 51 corresponding to the strip coils 2 on the same vertical line in the adjacent discharging groups 2 are inclined inward. In this embodiment, the angle formed by the vertical line L4 and the straight line L5 is b, and the value range of b is 5° to 10°. Thus, the discharging group 2 can be inclined with respect to the horizontal line L3, facilitating the strip to be more easily wound out from the strip coil assembly 6. And through the guide wheel assembly 5, the winding direction of the strip can be adjusted, so that the winding directions of the strips in the adjacent discharging groups 2 are different, effectively preventing the strip from being wound during the process of being wound out to the support wheel assembly 7.

[0035] As Figure 4 shown, there are two or more support wheel assemblies 7. Two or more support wheel assemblies 7 are on the same straight line to form a strip support area 8. In this embodiment, four support wheel assemblies 7 are provided. The support wheel assemblies 7 are arranged below the discharging area 2. The support wheel assembly 7 includes a first mounting seat 71, a first fixed shaft 72 and a support wheel 73. The first mounting seat 71 is fixedly arranged on one side of the hanging plate 1. One end of the first fixed shaft 72 is fixed on the first mounting seat 71, and the other end of the first fixed shaft 72 extends outward perpendicular to the hanging plate 1 to form a free end. The support wheel 73 is sleeved on the first fixed shaft 72. There are two or more strip grooves 74 on the support wheel 73 that match the strip, thereby preventing the strips wound out from different strip unwinding assemblies from being wound when passing through the same support wheel 73. At the same time, it is convenient for the strip wound out from the strip unwinding assembly 6 to pass through the support wheel 73, playing a guiding role for the strip and changing the direction of the strip, so that the strip enters the next process through the support wheel 73.

[0036] As Figure 5As shown in the figure, one side of the hanging plate 1 is provided with a fixing plate 11. The fixing plate 11 is arranged on one side of the solder tape support area 8. There are more than two tension wheel assemblies 9 on the fixing plate 11. The tension wheel assemblies 9 are arranged along the length direction of the fixing plate 11. The tension wheel assembly 9 includes a second mounting seat 91, a second fixing shaft 92 and a tension wheel 93. The second mounting seat 91 is fixedly arranged on the fixing plate 11. One end of the second fixing shaft 92 is fixed on the second mounting seat 91, and the other end of the second fixing shaft 92 extends outward perpendicular to the fixing plate 11 to form a free end. The tension wheel 93 is sleeved on the second fixing shaft 92. There are more than two receiving grooves 94 on the tension wheel 93 that match the solder tape, which can prevent the solder tape wound out from different support wheel assemblies 7 from being entangled when passing through the same tension wheel 93. At the same time, it is convenient for the solder tape to change direction after passing through the solder tape support area 8 and be tensioned by the tension wheel assembly 9 on the fixing plate 11 to prevent the solder tape from becoming loose.

[0037] The working principle of the present utility model: By arranging the solder tape unwinding assembly 6 obliquely, the driving device drives the material roll 61 to rotate obliquely, thereby facilitating the unwinding of the solder tape in the material roll 61, and enabling the solder tape to pass through the guide wheel assembly 5 arranged on the lower left side of the material roll assembly 6. At the same time, by arranging the material rolls 61 in adjacent two sets of discharging groups on the same vertical line, and making the vertical line form an angle with the straight line where the centers of the guide wheels corresponding to the material rolls on the same vertical line in adjacent two sets are located. For example, the first material roll assemblies 6 in each of the three discharging groups are on the same vertical line, and the guide wheel assemblies 5 corresponding to the first material roll assemblies 6 in each of the three discharging groups are also on the same vertical line, and an included angle is formed between the two straight lines. In this way, the direction of the solder tape unwound in each discharging group can be adjusted through the guide wheel assembly, so that the unwinding directions of the solder tapes in adjacent discharging groups are different, thereby effectively preventing the solder tape from being entangled during the process of being unwound to the support wheel assembly. Finally, the solder tape passing through the support wheel assembly is tensioned by the tension wheel assembly and then enters the next process.
