Description

Technical Field

[0001] The present application relates to the technical field of welding strip production, and in particular to an L-shaped cross-section welding strip forming device. Background Art

[0002] The solder strips used in photovoltaic modules need to go through a winding process after the copper strips are tinned in a tin furnace to become solder strips. The winding device winds the solder strips into discs, which are then transported through the internal logistics of the workshop to the cutting process. The pay-off reel of the cutting device releases the discs of solder strips and enters the cutting machine body to cut the solder strips according to pre-set parameters. The cut sections of solder strips are then selected and packaged according to their quality to become finished products.

[0003] During the production process, since some welding strips require an L-shaped cross-section, a pressing device is required to perform pressing processing before cutting to make the cross-section of the welding strip L-shaped, and then transport it to the cutting device for cutting. The whole process lengthens the corresponding production line due to multiple transfers, thereby reducing the production efficiency of the welding strip, so it needs further improvement. Utility Model Content

[0004] In order to improve the production efficiency of welding strips, the present application provides an L-shaped cross-section welding strip forming device.

[0005] The present application provides an L-shaped cross-section welding strip forming device, which adopts the following technical solution:

[0006] An L-shaped cross-section welding strip forming device comprises a frame, an unwinding disk rotatably connected to the frame for unwinding the welding strip, a leveling component arranged on the frame for leveling the welding strip, and a cutting component arranged on the frame for cutting the welding strip; the leveling component comprises a transmission channel for the welding strip to pass through, leveling wheels arranged on both sides of the welding strip, and a first driving member for driving the leveling wheel to rotate, wherein one of the leveling wheels is coaxially provided with a folding wheel, the diameter of the folding wheel is larger than the diameter of the leveling wheel, and the welding strip is partially exposed from the leveling wheel.

[0007] By adopting the above technical solution, after the welding strip is conveyed to the leveling wheel through the conveying channel for leveling, during the leveling process, the welding strip is conveyed to the leveling wheel by the folding wheel, because the diameter of the folding wheel is larger than the diameter of the leveling wheel, and is pressed by the folding wheel to bend and shape as the leveling wheel rotates, so that the cross section of the welding strip after subsequent cutting is L-shaped. Through the folding wheel, the welding strip can be folded during the cutting process, and then cut by the cutting assembly, so as to reduce the transportation time spent on folding the welding strip by another edge pressing device and then conveying it to the cutting device for disassembly, so as to speed up the production efficiency of the welding strip. Moreover, the setting of the folding wheel also reduces the overall economic cost compared with the edge pressing device.

[0008] Preferably, the folding wheel is detachably connected to the leveling wheel.

[0009] By adopting the above technical solution, the folding wheel is detachably connected to the leveling wheel, so that the leveling wheel of the corresponding size can be replaced according to demand to produce L-section welding strips of different specifications, and it is also convenient to disassemble and replace the folding wheel that is damaged during use.

[0010] Preferably, the first driving member includes a rotating shaft coaxially passed through the leveling wheel and a driving motor driving the rotating shaft to rotate, the outer peripheral wall of the rotating shaft away from the end of the leveling wheel is provided with a thread, the rotating shaft is provided with a second nut threadedly connected to the thread, the folding wheel is penetrated by a through hole for the rotating shaft to pass through, and the second nut abuts against the folding wheel.

[0011] By adopting the above technical solution, through the threaded connection between the second nut and the rotating shaft, the side wheel can be easily disassembled from the rotating shaft for replacement, and it is also convenient for installation.

[0012] Preferably, the folding wheel is made of plastic.

[0013] By adopting the above technical solution, since the folding wheel is made of plastic, the possibility of deformation caused by the reaction force of the welding strip can be reduced.

[0014] Preferably, the conveying channel is detachably connected to the frame.

[0015] By adopting the above technical solution, the conveying channels of different specifications suitable for the soldering strip can be replaced according to the needs, so as to reduce the possibility of deviation of the soldering strip during the conveying process.

[0016] Preferably, the cutting assembly includes a cutting table arranged on a frame, a cutting knife arranged above the cutting machine, and a second driving member for driving the cutting knife to rise and fall. A limiting ring is arranged on the upper end surface of the cutting table, and the welding strip is passed through the limiting ring.

[0017] By adopting the above technical solution, the second driving member is started to drive the cutting knife to cut the welding strip, which has been set in an L-shaped cross-section, into the required length. In order to reduce the possibility of deviation of the uncut part during the cutting process, the limiting ring is set to limit the position.

[0018] Preferably, the cutting table is detachably connected to the frame.

[0019] By adopting the above technical solution, the cutting table can be detachably connected to the frame for replacement, so as to adapt to welding strips of different widths for positioning, thereby improving adaptability.

[0020] Preferably, a plurality of leveling wheels are arranged at intervals along the length direction of the welding strip.

[0021] By adopting the above technical solution, since a number of leveling wheels are arranged at intervals along the length direction of the welding strip, and the leveling wheels are detachably connected to the rotating shaft, a corresponding number of leveling wheels can be added according to needs, so as to increase or decrease the number of leveling wheels according to the required leveling effect of the welding strip.

[0022] Preferably, the frame is provided with a collecting trough below the cutting assembly.

[0023] By adopting the above technical solution, a collecting trough is provided to receive the cut welding strips.

[0024] In summary, the utility model has the following beneficial effects:

[0025] By setting the hemming wheel, since the diameter of the hemming wheel is larger than the diameter of the leveling wheel, the hemming wheel is pressed to bend and shape as the leveling wheel rotates, so that the cross section of the welding strip after subsequent cutting is set in an L-shape. This reduces the need for another edge pressing device to perform hemming processing and then transfer it to the cutting device for disassembly, thereby speeding up the production efficiency of the welding strip and reducing the overall economic cost.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 , further details of this application are given.

[0031] The embodiment of the present application discloses a device for forming an L-shaped cross-section welding strip.

[0032] Example:

[0033] An L-shaped cross-section welding strip forming device, referring to Figure 1 , including a frame 2, an unwinding reel 3 rotatably connected to the frame 2 for unwinding the welding strip 1, a leveling component 4 arranged on the frame 2 for leveling the welding strip 1, and a cutting component 5 arranged on the frame 2 for cutting the leveled welding strip 1.

[0034] Reference Figure 1 , Figure 2 , wherein a support rod 21 is fixedly connected to one side wall of the frame 2. In this embodiment, the length direction of the support rod 21 is parallel to the length direction of the frame 2. A mounting rod 22 is provided at one end of the support rod 21 away from the frame 2. The length direction of the mounting rod 22 is perpendicular to the length direction of the support rod 21, and the middle part of the mounting rod 22 is fixed to the end face of the support rod 21. In this embodiment, a rotating rod 23 is coaxially fixedly connected to both ends of the mounting rod 22. A through hole 31 is provided in the middle part of the unwinding disk 3. The rotating rod 23 is penetrated through the through hole 31, so that the unwinding disk 3 is slidably sleeved on the rotating rod 23. In order to reduce the possibility that the unwinding disk 3 slips and separates from the rotating rod 23 during the unwinding process driven by the leveling assembly 4, in this embodiment, the rotating rod 23 is threadedly connected with a first nut 231.

[0035] Among them, the leveling component 4 specifically includes a transmission channel 41 for the welding strip 1 to pass through, leveling wheels 42 arranged on both sides of the welding strip 1, and a first driving member 43 for driving the leveling wheel 42 to rotate. In this embodiment, since the welding strip 1 is arranged in a strip shape, the transmission channel 41 is specifically a hollow tube arrangement with a rectangular cross-section, and the length direction of the transmission channel 41 is parallel to the length direction of the frame 2.

[0036] Reference Figure 1 , Figure 3 , the conveying channel 41 is detachably connected to the side wall of the frame 2. Specifically, a mounting block 24 is protruded and fixed on the side wall of the frame 2. Two mounting blocks 24 are provided and are respectively arranged on the upper surface and the lower surface of the conveying channel 41, and are arranged oppositely. The distance between the two mounting blocks 24 is greater than the thickness of the conveying channel 41. The mounting block 24 located above the conveying channel 41 is threaded with a first bolt 241, and the lower end of the first bolt 241 is tightly pressed against the upper surface of the conveying channel 41 to install the conveying channel 41 on the frame 2. It should be noted that since the first bolt 241 is tightly set, the relative position of the conveying channel 41 and the mounting block 24 in the horizontal direction can be adjusted according to needs.

[0037] Among them, in this embodiment, the axis of the leveling wheel 42 is perpendicular to the length direction of the conveying channel 41, and a number of leveling wheels 42 are arranged at intervals along the length direction of the welding strip 1. The specific number is set according to demand. It should be noted that there are at least two leveling wheels 42, and the rotation direction of the leveling wheel 42 is set in the direction of the cutting component 5.

[0038] The first driving member 43 includes a rotating shaft 431 coaxially inserted in the leveling wheel 42 and a driving motor (not shown in the figure) driving the rotating shaft 431 to rotate. In this embodiment, there are several rotating shafts 431. The outer peripheral wall of the rotating shaft 431 is provided with a limiting groove 6 along its axial direction. The limiting groove 6 extends to the end face of the fixing ring away from the frame 2. The flat wheel is penetrated by a first through hole for the fixing ring to pass through. The inner peripheral wall of the first through hole is protrudingly provided with a limiting strip 421. The limiting strip 421 is slidably inserted in the limiting groove 6, so that the leveling wheel 42 and the rotating shaft 431 can rotate coaxially. The end of the rotating shaft 431 away from the leveling wheel 42 is coaxially fixedly connected with a screw rod 7. The rotating shaft 431 is provided with a second nut 71 threadedly connected to the screw rod 7. It should be noted that the driving motor is built into the frame 2. Since the driving rotating shaft 431 to rotate is a prior art, it will not be described in detail here.

[0039] Furthermore, one of the leveling wheels 42 is coaxially provided with a folding wheel 8, which is specifically arranged above the welding strip 1. In the present embodiment, the folding wheel 8 is made of plastic, and the diameter of the folding wheel 8 is larger than the diameter of the leveling wheel 42. It should be noted that the welding strip 1 is partially exposed from the leveling wheel 42 so that the welding strip 1 can be folded under pressure when it is transferred to the folding wheel 8. At this time, the screw 7 is passed through the folding wheel 8, and the second nut 71 abuts against the folding wheel 8.

[0040] Furthermore, in order to reduce the possibility of relative rotation between the hemming wheel 8 and the rotating shaft 431 during the rotation process, in this embodiment, the hemming wheel 8 can be threadedly sleeved on the screw rod 7.

[0041] Among them, the cutting assembly 5 includes a cutting table 51 detachably connected to the side wall of the frame 2, a cutting knife 52 arranged above the cutting machine, and a second driving member 53 for driving the cutting knife 52 to rise and fall. In this embodiment, the length direction of the cutting table 51 is perpendicular to the length direction of the welding strip 1, and the upper end surface of the cutting table 51 is fixedly connected to the limiting ring 511, and the welding strip 1 is passed through the limiting ring 511. The opposite side walls of the cutting table 51 are provided with a fixing block 25, and the fixing block 25 is fixedly connected to the side wall of the frame 2. The fixing block 25 is threaded with a second bolt 251, and the second bolt 251 is pressed against the fixing block 25 to fix the cutting table 51. The second bolt 251 is used to replace the cutting table 51. It should be noted that the second driving member 53 and the cutting knife 52 are both existing technologies and will not be described in detail here.

[0042] Back to Figure 1The frame 2 is located below the cutting assembly 5 and is provided with a collecting trough 26 for collecting the cut L-shaped cross-section welding strip 1.

[0043] The implementation principle of the L-shaped cross-section welding strip 1 forming device of the present application embodiment is as follows: the driving motor is started to drive the leveling wheel 42 to move toward the direction close to the cutting knife 52. When the required length of the welding strip 1 reaches the requirement, the second driving member 53 is started to drive the cutting knife 52 to cut the welding strip 1 so that it falls into the collection tank 26 below for collection. Before cutting, due to the folding wheel 8, the welding strip 1 can be folded during the cutting process to reduce the need to set up another edge pressing device for folding and then conveying it to the cutting device for disassembly, so as to speed up the production efficiency of the welding strip 1.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
