Description

Technical Field

[0001] This application relates to the field of solar panel production equipment technology, and in particular to an EPE film welding device. Background Technology

[0002] In the manufacturing process of photovoltaic panels, the shingling process refers to welding busbars to the ends of already welded cell strings. To avoid short circuits between the positive and negative busbars and to prevent breakage due to vibration, an EPE film is usually applied to the busbars. Because a single layer of EPE film is relatively thin, current processes typically involve placing one EVA film and one EPE film separately at the busbar lead-out positions. This two-step placement results in a low cycle time and low work efficiency. Summary of the Invention

[0003] This application provides an EPE film welding device to solve the problems existing in related technologies. The technical solution is as follows:

[0004] This application provides an EPE film welding apparatus, including:

[0005] A rotary placement mechanism includes a rotary drive assembly and a placement platform. The rotary drive assembly is connected to the center of the placement platform. The rotary drive assembly drives the placement platform to rotate around its center line. The center line of the placement platform has welding positions on both sides.

[0006] A welding mechanism includes a welding assembly and a welding drive assembly. The welding drive assembly is connected to the welding assembly and drives the welding assembly to move toward or away from the placement platform. The welding assembly includes a welding plate with a heating rod mounted on it. The welding plate is located above the placement platform.

[0007] In one embodiment, the rotary drive assembly includes a rotary mounting base and a rotary cylinder, the rotary cylinder being fixed to the rotary mounting base and connected to the center of the placement platform.

[0008] In one embodiment, the two ends of the rotating fixed base are threaded with steel ball rollers, and the placement platform is slidably connected to the steel ball rollers.

[0009] In one embodiment, a fixing clip for fitting an EPE film is fixed on the welding position, and a vacuum adsorption hole is also provided on the welding position.

[0010] In one embodiment, the welding mechanism further includes a welding lifting assembly, the welding drive assembly is connected to the welding lifting assembly, the welding lifting assembly is connected to the welding plate, and the welding lifting assembly drives the welding plate to rise and fall.

[0011] In one embodiment, the welding lifting assembly includes a welding fixing seat and a lifting cylinder, wherein the lifting cylinder is fixed on the welding fixing seat and is connected to the welding plate.

[0012] In one embodiment, the welding assembly further includes a welding fixing plate, a connecting rod, an elastic element, and a connecting plate. The welding fixing plate is connected to the welding lifting assembly. The top of the connecting rod is slidably connected to the welding fixing plate, and the bottom of the connecting rod is connected to the connecting plate. The connecting plate is connected to the welding plate. The elastic element is sleeved on the connecting rod, and both ends of the elastic element abut against the welding fixing plate and the connecting plate, respectively.

[0013] In one embodiment, the welding mechanism further includes an anti-slipping component, which includes an anti-slipping fixing seat and an anti-slipping rod. The anti-slipping fixing seat is movably connected to the welding fixing seat, and the anti-slipping rod is connected to the anti-slipping fixing seat. The bottom of the welding plate has a groove recessed toward the center of the welding plate, and the anti-slipping rod is located below the groove.

[0014] In one embodiment, the welding drive assembly includes a slide rail, a slide rail fixing plate, and a drive cylinder.

[0016] The advantages or beneficial effects of the above technical solutions include at least the following:

[0017] The EPE film welding apparatus of this application embodiment includes a rotary placement mechanism and a welding mechanism. Since the rotary placement mechanism includes a rotary drive assembly and a placement platform, and the rotary drive assembly can drive the placement platform to rotate around its centerline, the EPE film welding apparatus, in use, first places two small pieces of EPE film on one side of the welding position. Then, the rotary drive assembly drives the placement platform to rotate 180 degrees. Next, the welding drive assembly drives the welding plate to move above the welding position, and the welding plate welds the two small pieces of EPE film together on that side. Then, an external robotic arm removes the welded EPE film pieces, and simultaneously, two small pieces of EPE film are placed on the welding position on the other side. Then, the placement platform is rotated 180 degrees again, and the welding plate welds the EPE film pieces on the other side. Because EPE film pieces can be placed and removed simultaneously at two welding positions, after the welded EPE film piece at one welding position is removed, the EPE film piece at the other welding position can be welded immediately. Furthermore, since welding two EPE film pieces is achieved, both pieces can be directly fitted onto the busbar at once, eliminating the need for separate placements. Therefore, the EPE film welding device of this embodiment can weld two EPE film pieces, accelerating the placement of double-layer EPE film pieces and improving work efficiency.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0027] like Figure 1 , Figure 3 As shown in the figure, this application provides an EPE film welding device, including a rotating placement mechanism 1 and a welding mechanism 2. The rotating placement mechanism 1 includes a rotating drive assembly 11 and a placement platform 12. The rotating drive assembly 11 is connected to the center of the placement platform 12, and drives the placement platform 12 to rotate around its centerline. Welding positions 121 are respectively located on both sides of the centerline of the placement platform 12. The welding mechanism 2 includes a welding assembly 21 and a welding drive assembly 22. The welding drive assembly 22 is connected to the welding assembly 21, and drives the welding assembly 21 to move closer to or further away from the placement platform 12. The welding assembly 21 includes a welding plate 211, on which a heating rod is mounted, and the welding plate 211 is located above the placement platform 12.

[0028] Since the rotating placement mechanism 1 includes a rotating drive assembly 11 and a placement platform 12, and the rotating drive assembly 11 can drive the placement platform 12 to rotate around the center line of the placement platform 12, when using the EPE film welding device, two pieces of EPE film 3 can first be placed on the welding position 121 on one side. Then, the rotating drive assembly 11 drives the placement platform 12 to rotate 180 degrees. Next, the welding drive assembly 22 drives the welding plate 211 to move above the welding position 121, and the welding plate 211 welds the two pieces of EPE film 3 on that side together. Then, an external robotic arm removes the welded EPE film 3, and at the same time, two pieces of EPE film 3 are placed on the welding position 121 on the other side. Then, the placement platform 12 is rotated 180 degrees again, and the welding plate 211 welds the EPE film 3 on the other side. Since the EPE membrane slab 3 can be placed and removed simultaneously at two welding positions 121, after the welded EPE membrane slab 3 on one welding position 121 is removed, the EPE membrane slab 3 on the other welding position 121 can then be welded. Furthermore, because the welding of two EPE membrane slabs 3 is achieved, both EPE membrane slabs 3 can be directly fitted onto the busbar at once, eliminating the need for two separate placements. Therefore, the EPE membrane welding device of this embodiment can achieve the welding of two EPE membrane slabs 3, while simultaneously accelerating the placement of double-layer EPE membrane slabs and improving work efficiency.

[0029] like Figure 2 As shown, to achieve the rotation of the placement platform 12, the rotation drive assembly 11 includes a rotation fixed base 111 and a rotation cylinder 112. The rotation cylinder 112 is fixed to the rotation fixed base 111 by bolts, and the rotation cylinder 112 is connected to the center of the placement platform 12. When the rotation cylinder 112 is activated, it can drive the placement platform 12 to rotate around its center line, thereby achieving the rotation of the placement platform 12 and adjusting the positions of the two welding positions 121 on the placement platform 12.

[0030] Furthermore, the two ends of the rotating fixed base 111 are threadedly connected to ball bearing rollers 13, and the placement platform 12 is slidably connected to the ball bearing rollers 13. The ball bearing rollers 13 can support the two ends of the placement platform 12 without affecting the rotation of the placement platform 12.

[0031] In one embodiment, to place the EPE film piece 3 on the welding position 121, a fixing clip 122 for fitting the EPE film piece 3 can be fixed on the welding position 121. The EPE film piece 3 has two punched holes pre-drilled on it before welding. When placing the EPE film piece 3 on the welding position 121, simply align the two punched holes on the EPE film piece 3 with the fixing clip 122, and then fit the EPE film piece 3 onto the fixing clip 122. In this embodiment, the fixing clip 122 not only fixes the EPE film piece 3 but also positions it, ensuring that the two EPE film pieces 3 completely overlap on the welding position 121.

[0032] In order to fix the clamp 122, a fixing rod 123 can be inserted inside the placement platform 12, and the bottom of the clamp 122 is inserted through the fixing rod 123, thereby fixing the clamp 122.

[0033] It should be noted that the fixing clips 122 on the two welding positions 121 can be placed in different directions or in the same direction.

[0034] In one embodiment, a vacuum adsorption hole 124 may be provided on the welding position 121. The vacuum adsorption hole 124 can adsorb the EPE film material 3 through the vacuum adsorption principle, thereby making the EPE film material 3 more firmly fixed on the welding position 121.

[0035] like Figure 1 , Figure 3 As shown, to achieve the welding of EPE film granules 3, the welding mechanism 2 further includes a welding lifting assembly 23. The welding drive assembly 22 is connected to the welding lifting assembly 23, and the welding lifting assembly 23 is connected to the welding plate 211. The welding lifting assembly 23 drives the welding plate 211 to rise and fall. Further, the welding lifting assembly 23 includes a welding fixing seat 231 and a lifting cylinder 232. The lifting cylinder 232 is fixed to the welding fixing seat 231 by bolts and is connected to the welding plate 211.

[0036] To connect the lifting cylinder 232 to the welding plate 211, the welding assembly 21 further includes a welding fixing plate 212, a connecting rod 213, an elastic element 214, and a connecting plate 215. The welding fixing plate 212 is connected to the piston rod of the lifting cylinder 232, and the lifting cylinder 232 drives the welding fixing plate 212 to rise and fall. The top of the connecting rod 213 is slidably connected to the welding fixing plate 212, and the bottom of the connecting rod 213 is connected to the connecting plate 215 by screws. The connecting plate 215 is connected to the welding plate 211 by bolts. The elastic element 214 is sleeved on the connecting rod 213, and both ends of the elastic element 214 abut against the welding fixing plate 212 and the connecting plate 215, respectively. Preferably, the elastic element 214 is a spring.

[0037] like Figure 4 As shown, in order to achieve a sliding connection between the connecting rod 213 and the welding fixing plate 212, a linear bearing 216 can be fixed on the welding fixing plate 212. The connecting rod 213 passes through the inside of the linear bearing 216, and the connecting rod 213 is slidably connected to the linear bearing 216.

[0038] In one embodiment, the number of connecting rods 213 can be four, each of which is fitted with a spring, and the tops of two opposite connecting rods 213 can be connected by a baffle 217 to prevent the connecting rods 213 from sliding out of the linear bearing 216.

[0039] When the lifting cylinder 232 moves the welding fixing plate 212 downward, the welding plate 211 moves downward through the connecting rod 213 and the elastic element 214; when the lifting cylinder 232 moves the welding fixing plate 212 upward, the welding plate 211 moves upward through the connecting rod 213 and the elastic element 214.

[0040] After welding plate 211 welds the EPE film piece 3, welding plate 211 needs to move upward. To prevent welding plate 211 from carrying away the EPE film piece 3 during upward movement, welding mechanism 2 also includes an anti-slip assembly 24. The anti-slip assembly 24 includes an anti-slip fixing seat 241 and an anti-slip rod 242. The anti-slip fixing seat 241 is movably connected to the welding fixing seat 231, and the anti-slip rod 242 is bolted to the anti-slip fixing seat 241. The bottom of welding plate 211 has a groove 2111 recessed towards the center of welding plate 211, and the anti-slip rod 242 is located below the groove 2111. Preferably, there are two anti-slip rods 242.

[0041] To achieve a movable connection between the anti-slip fixing seat 241 and the welding fixing seat 231, a movable connecting groove 2411 can be provided on the anti-slip fixing seat 241, and a bolt can be fixed on the welding fixing seat 231, with the bolt located within the movable connecting groove 2411. When the bolt is tightened, the anti-slip fixing seat 241 and the welding fixing seat 231 can be fixed; when the bolt is loosened, the anti-slip fixing seat 241 can be moved up and down, thereby adjusting its position.

[0042] To enable heating and welding of the welding plate 211, heating rods are installed inside the welding plate 211, with the heating rods located on both sides of the groove 2111. Welding points are also located on both sides of the groove 2111. Heating by the heating rods allows for the welding of two EPE film pieces 3. When the bottom of the welding plate 211 contacts the EPE film piece 3, the two pieces are welded together by the heating rods. As the welding plate 211 moves upward after welding, the two anti-material guide rods, positioned above the EPE film piece 3, prevent the EPE film piece 3 from being carried away by the welding plate 211.

[0043] In one embodiment, such as Figure 1 As shown, to enable the movement of the welding mechanism 2, the welding drive assembly 22 includes a slide rail 221, a slide rail fixing plate 222, and a drive cylinder 223. The slide rail 221 is fixed to the slide rail fixing plate 222, and the drive cylinder 223 is fixed to the rotating fixed seat 111. The piston rod of the drive cylinder 223 is connected to the welding fixed seat 231, and the welding fixed seat 231 is slidably connected to the slide rail 221. After the drive cylinder 223 is activated, it can drive the welding fixed seat 231 to move along the slide rail 221, thereby moving the welding plate 211 to above the welding position 121, or removing the welding plate 211 from above the welding position 121.

[0044] In one embodiment, an adjusting plate 4 is fixed to one side of the slide rail fixing plate 222, the rotating fixing seat 111 is movably connected to the adjusting plate 4, and the rotating fixing seat 111 is slidably connected to the slide rail 221.

[0045] Specifically, an adjustment groove 41 can be provided along the length of the adjustment plate 4, and a bolt is fixed on the rotating fixed seat 111, with the bolt located inside the adjustment groove 41. When the bolt is tightened, the rotating fixed seat 111 can be fixed to the adjustment plate 4; when the bolt is loosened, the rotating fixed seat 111 can be driven to slide along the slide rail 221, thereby adjusting the position of the rotating fixed seat 111.

[0046] It should be noted that the EPE film pieces 3 can all be placed and removed by robotic arms, and the two robotic arms can be located on opposite sides of the rotating placement mechanism 1. The aforementioned EPE film pieces 3 can also be replaced with EVA film pieces.
