The solder ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the solder ribbon will directly affect the current collection efficiency of the photovoltaic module and has a great impact on the power of the photovoltaic module.

Detailed implementation manners

[0036] In order to make the objectives, technical solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0037] Referring to Figures 1-11 , an embodiment of the present invention provides a wire reel that can be self-maintained, including a solder tape processing device 1, a wire reel body 2 is installed on the solder tape processing device 1, the solder tape processing device 1 and the wire reel body 2 are connected via a connecting member 3, and an oil injection assembly 4 is also installed on the solder tape processing device 1, and the oil injection assembly 4 is connected to the connecting member 3. By installing the connecting member 3, not only can the rotational connection between the solder tape processing device 1 and the wire reel body 2 be realized, but also the self-heating of the connecting member 3 can be realized, which extends the service life of the connecting member 3, and with the assistance of the oil injection assembly 4, the connecting member 3 can be self-lubricated, thereby ensuring that the connecting member 3 can be maintained in a timely manner.

[0038] It should be further noted here that the solder tape processing device 1 is an existing solder tape processing equipment, which will not be elaborated here.

[0039] Referring to Figures 4-6 , the connecting member 3 includes an assembly table 31 and a slewing bearing 32, and the slewing bearing 32 includes a connecting outer cylinder 321 and a number of movable steel balls 322; a passage 3101 is reserved on the assembly table 31, and the passage 3101 is used to introduce air for heat dissipation.

[0040] The slewing bearing 32 includes a connecting outer cylinder 321 and a number of movable steel balls 322. The connecting outer cylinder 321 is installed inside the assembly table 31, and a connecting passage 32101 is reserved on the connecting outer cylinder 321. The connecting passage 32101 is connected to the passage 3101, and air can flow into the inside of the connecting outer cylinder 321 through the passage 3101 and the connecting passage 32101; a number of movable steel balls 322 are arranged along the circumferential direction of the connecting outer cylinder 321 and are movably attached to the inner surface of the connecting outer cylinder 321, and air can leak out through the gaps between adjacent movable steel balls 322.

[0041] Through the installation of the slewing bearing 32, air sequentially flows from the first passage 3101 and the connecting passage 32101 to the inside of the slewing bearing 32, achieving heat removal for the slewing bearing 32. When the air flows into the first passage 3101, it removes heat from the assembly table 31. When it flows into the connecting passage 32101, it removes heat from the connecting outer cylinder 321. After flowing into the inside of the connecting outer cylinder 321, it transfers heat by contacting the inner surface of the connecting outer cylinder 321 and the movable steel balls 322. The air after heat transfer leaks out through the gaps between the movable steel balls 322, discharging the hot air inside the slewing bearing 32, so as to prevent the slewing bearing 32 from rising to a high temperature, and then preventing the solder tape processing device 1 from malfunctioning due to the damage of the slewing bearing 32.

[0042] Refer to Figure 4 , the slewing bearing 32 further includes a connecting inner cylinder 323. The connecting inner cylinder 323 is installed inside the connecting outer cylinder 321, and the movable steel balls 322 are located between the connecting outer cylinder 321 and the connecting inner cylinder 323. The connecting inner cylinder 323 is clamped on the outer peripheral surface of the rotating column 35 and rotates together with the rotating column 35. One end of the rotating column 35 extends out of the assembly table 31 and is detachably connected to the wire wheel body 2, and the other end of the rotating column 35 extends out of the assembly table 31 and is connected to the motor inside the solder tape processing device 1.

[0043] The assembly table 31 includes a head and a tail. The head and the tail are connected into a convex-shaped structure. The head is used to connect to the solder tape processing device 1. The diameter of the outer peripheral surface of the tail is smaller than that of the outer peripheral surface of the head, thereby ensuring stronger firmness. The first passage 3101 is reserved on the tail. The inlet of the first passage 3101 is connected to the compressor through a rubber tube, and the compressor can inject cold air into the first passage 3101 to achieve heat transfer and heat removal.

[0044] Refer to Figure 6 , the center line of the first passage 3101 intersects with the vertical plane, and the angle between the vertical plane and the center line of the assembly table 31 is 90 degrees. The first passage 3101 is arranged obliquely, which can extend the first passage 3101, thereby increasing the range of contact between the air and the assembly table 31, and then increasing the heat transfer range between the air and the assembly table 31, making the heat removal function stronger. The center line of the first passage 3101 is in the vertical section. The angle between the center line of the first passage 3101 and the vertical plane is 40 degrees. The exhaust part of the first passage 3101 is arranged facing the inlet of the connecting passage 32101, so that the flow rate at the inlet of the connecting passage 32101 is the largest. The inlet and the exhaust part of the first passage 3101 are both annular, and the inside of the first passage 3101 is cylindrical, which is convenient for connection with the rubber tube.

[0045] Two slewing bearings 32 are used, which can jointly bear the load, thereby ensuring that the slewing bearing 32 can operate longer under the same operating environment and extending the maintenance and repair cycle.

[0046] The connecting outer cylinder 321 includes outer cylinder one 3211 and outer cylinder two 3212 which are arranged face to face. A notch one 32111 is reserved on one side of outer cylinder one 3211 facing outer cylinder two 3212. A notch four is reserved on one side of outer cylinder two 3212 facing outer cylinder one 3211. Notch one 32111 and notch four are directly opposite to form a connecting passage 32101. The movable steel balls 322 include steel ball one 3221 and steel ball two 3222. A number of steel ball one 3221 are arranged inside outer cylinder one 3211 and are movably attached to the inner surface of outer cylinder one 3211. A number of steel ball two 3222 are arranged inside outer cylinder two 3212 and are movably attached to the inner surface of outer cylinder two 3212. The gaps include gap A between adjacent steel ball one 3221 and gap B between adjacent steel ball two 3222. When the slewing bearing 32 uses this structure, the connecting passage 32101 is located between steel ball one 3221 and steel ball two 3222. After the air flows into the inside of the connecting outer cylinder 321, it can fully contact and transfer heat with outer cylinder one 3211, outer cylinder two 3212, steel ball one 3221, steel ball two 3222 and the connecting inner cylinder 323, and then leak out through gap A and gap B respectively.

[0047] Refer to Figures 7-9 , a passage two 32114 arranged along the circumferential direction of outer cylinder one 3211 is reserved inside outer cylinder one 3211. An air inlet one 32113 is reserved on the side wall of notch one 32111. A notch three 32115 is reserved on one side of outer cylinder one 3211 facing outer cylinder two 3212. An exhaust hole one 32117 is reserved on the side wall of notch three 32115. Air inlet one 32113 and exhaust hole one 32117 are respectively connected to passage two 32114. Air can flow into passage two 32114 through air inlet one 32113 and be discharged through exhaust hole one 32117; and / or, a passage three arranged along the circumferential direction of outer cylinder two 3212 is reserved inside outer cylinder two 3212. An air inlet two is reserved on the side wall of notch four. A notch five is reserved on one side of outer cylinder two 3212 facing outer cylinder two 3212. An exhaust hole two is reserved on the side wall of notch five. Air inlet two and exhaust hole two are respectively connected to passage three. Air can flow into passage three through air inlet two and leak out through exhaust hole two.

[0048] Heat can be dissipated only through the passage reserved on one of the connecting outer cylinders 321. Taking the passage reserved on the outer cylinder 3211 as an example, after the air flow reaches the connecting passage 32101, some air flows downward into the inside of the connecting outer cylinder 321, touches and dissipates heat with the inner surface of the connecting outer cylinder 321, the movable steel balls 322 and the outer surface of the connecting inner cylinder 323, and then leaks out through the gaps between the adjacent movable steel balls 322; some other air flows into the passage 32114 through the air inlet 32113, conducts heat transfer with the outer cylinder 3211, and then leaks out through the exhaust holes 32117 respectively, discharging the high-temperature air inside the outer cylinder 3211. The leaked air flows into the inside of the connecting outer cylinder 321 and then leaks out through the gaps between the adjacent movable steel balls 322. Through the passage 32114 reserved on the outer cylinder 3211, the flowing time and distance of the air inside the slewing bearing 32 are extended, and thus the heat transfer range between the air and the slewing bearing 32 is also expanded, strengthening the heat transfer function. And heat can also be dissipated only through the passage reserved on the outer cylinder 3212, which has the same effect as the above-mentioned heat dissipation through the passage reserved only on the outer cylinder 3211.

[0049] Passages 32114 and 3 can also be reserved on the outer cylinder 3211 and the outer cylinder 3212 respectively. When grooves for heat dissipation are reserved on a pair of connecting outer cylinders 321, when the air flow reaches the connecting passage 32101, some air flows downward into the inside of the connecting outer cylinder 321, conducts contact heat transfer with the inner surface of the connecting outer cylinder 321, the movable steel balls 322 and the outer surface of the connecting inner cylinder 323, and then leaks out through the gaps between the adjacent movable steel balls 322; some air flows into the passage 32114 through the air inlet 32113, dissipates heat with the outer cylinder 3211, and then leaks out through the exhaust holes 32117, discharging the high-temperature air inside the outer cylinder 3211. The leaked air flows into the inside of the connecting outer cylinder 321 and then leaks out through the gaps between the adjacent movable steel balls 322; some air flows into the passage 3 through the second air inlet, conducts heat transfer with the outer cylinder 3212, and then leaks out through the second exhaust hole, discharging the high-temperature air inside the outer cylinder 3212. The leaked air flows to the inside of the connecting outer cylinder 321 and then leaks out through the gaps between the adjacent movable steel balls 322. The notch 32115 and the notch 5 can be arranged face to face or staggered. The spans of the passage 32114 and the passage 3 can be the same or different.

[0050] The number of the third notches 32115 is a pair. The pair of the third notches 32115 are respectively located on both sides of the first notch 32111. The side walls of each of the third notches 32115 are reserved with the first exhaust holes 32117. The pair of the first exhaust holes 32117 are respectively connected to both ends of the second passage 32114. The first air inlet hole 32113 is connected to the middle of the second passage 32114. After the air flows from the first air inlet hole 32113 into the second passage 32114, it changes towards both sides of the first outer cylinder 3211 respectively, and then leaks out from the pair of the first exhaust holes 32117 respectively. Through the first exhaust holes 32117 reserved at both ends of the second passage 32114, the air can pass through every place in the second passage 32114 to prevent some areas in it from not being able to transfer heat. The number of the fifth notches is a pair. The pair of the fifth notches are respectively located on both sides of the fourth notch. The side walls of each of the fifth notches are reserved with the second exhaust holes. The pair of the second exhaust holes are respectively connected to both ends of the third passage. The second air inlet hole is connected to the middle of the third passage. The functions of the fifth notch and the third passage are the same as those of the third notch 32115 and the second passage 32114.

[0051] Referring to Figure 5 With Figure 6 , there is a storage space reserved on the connecting outer cylinder 321 that passes through the connecting outer cylinder 321. The storage space and the inner surface of the assembly table 31 form a storage chamber 32102, and the storage chamber 32102 is used to store engine oil. The engine oil can form a protective film inside the slewing bearing 32, reducing the resistance between the moving steel balls 322 and the connecting outer cylinder 321, and then reducing the consumption and enhancing the performance of the device; and the engine oil can transfer heat to the slewing bearing 32 during the rotation of the slewing bearing 32 to prevent the slewing bearing 32 from being damaged due to overheating; in addition, the protective film can enhance the function of the slewing bearing 32 to withstand compression and support, and extend the maintenance and repair cycle of the slewing bearing 32. By arranging the storage chamber 32102 inside the slewing bearing 32, some engine oil can be stored, and then the inside of the slewing bearing 32 can be kept in constant contact with the engine oil.

[0052] The connecting outer cylinder 321 includes the first outer cylinder 3211 and the second outer cylinder 3212 arranged opposite to each other. On one side where the first outer cylinder 3211 and the second outer cylinder 3212 are in contact with each other, there is a second notch 32112 reserved. On one side where the second outer cylinder 3212 and the first outer cylinder 3211 are in contact with each other, there is a sixth notch reserved. The second notch 32112 and the sixth notch are arranged opposite to each other to form a storage space. The transverse sections of the second notch 32112 and the sixth notch are both rectangular, and then the transverse section of the storage space is rectangular. The bent parts of the second notch 32112 and the sixth notch are both arc-shaped. The transverse sections of the second notch 32112 and the sixth notch can also be arc-shaped, and then the storage space is cylindrical.

[0053] The first passage 3101 is at the upper end of the assembly table 31. The connection passage 32101 is at the upper end of the connection outer cylinder 321. The storage chamber 32102 is at the lower end of the connection outer cylinder 321. Since the heated air moves upward inside the slewing bearing 32, arranging the first passage 3101 and the connection passage 32101 at the upper end of the connection outer cylinder 321 allows full heat transfer between the hot air and the cold air. By arranging the storage space at the lower end of the connection outer cylinder 321, the engine oil can be filled in a dispersed manner to ensure the integrity of the protective film and extend the working cycle of the slewing bearing 32. There is one storage space, and the storage space is arranged face to face with the connection passage 32101.

[0054] Refer to Figure 5 and Figure 6 On the wall surface of the assembly table 31, a heat removal port 311 is reserved. The heat removal port 311 extends along the radial direction of the wall surface of the assembly table 31, and the farther end of the heat removal port 311 from the center of the assembly table 31 is connected to the outside. The heat removal port 311 can enhance the heat removal function of the assembly table 31 and perform heat removal on the assembly table 31 through the flow of air changing inside the heat removal port 311.

[0055] A disc 33 is installed on the wall surface of the assembly table 31, and a rubber sheet 34 is installed between the disc 33 and the connection outer cylinder 321. By installing the rubber sheet 34, the oscillation during the operation of the slewing bearing 32 can be reduced, the wear of the slewing bearing 32 can be alleviated, and the damage of the slewing bearing 32 can be prevented; and the installation of the rubber sheet 34 is conducive to blocking the external conditions that may cause corrosion when the slewing bearing 32 touches, thereby enhancing the protection of the slewing bearing 32. With the above solutions, the working cycle of the slewing bearing 32 is longer, and the number of inspections of the slewing bearing 32 is reduced. The disc 33 can press the rubber sheet 34, and the disc 33 can be installed on the assembly table 31 through a tensioning screw.

[0056] A circular opening 312 is reserved on the wall surface of the assembly table 31. The outer peripheral surface of the rubber sheet 34 is located in the circular opening 312, and the rubber sheet 34 is attached to the wall surface of the connection outer cylinder 321. The installation of the circular opening 312 can position the rubber sheet 34 during installation to prevent the rubber sheet 34 from shifting during installation and ensure the working stability of the slewing bearing 32. The position where the inner peripheral surface of the rubber sheet 34 extends out of the circular opening 312 is pressed against the wall surface of the connection outer cylinder 321.

[0057] Refer to Figures 1-3 and Figure 6 、 Figure 10 and Figure 11The oil filling assembly 4 includes a slide 41 and a guide groove 42 reserved at the lower end of the assembly table 31, and a control rod 47 fixed to the outer circumference of the rotating column 35. The guide groove 42 runs through the slide 41. The upper end of the guide groove 42 is connected to the lower end of the storage chamber 32102. The guide groove 42 and the slide 41 are arranged in a cross shape. A movable column 43 is slidably installed in the slide 41. One end of the movable column 43 is connected to the bottom of the slide 41 via a spiral beryllium copper wire 48. At the beginning, One end of the movable column 43 is at the connection point between the slide 41 and the conducting groove 42, which is used to block the conducting groove 42. A skewed surface is reserved at one end of the movable column 43, and the skewed surface is on the rotation trajectory of the control rod 47. A conducting hole 44 is reserved on the movable column 43. The lower end of the conducting groove 42 is connected to the connecting pipe 45, and the other end of the connecting pipe 45 is connected to the storage box 46. The storage box 46 is installed on the welding strip processing device 1, and the storage box 46 is above the connecting piece 3. The control rod 47 rotates together with the rotating column 35. When the rotating column 35 rotates to the inclined surface of the movable column 43 and continues to rotate, the control rod 47 presses the movable column 43 to slide toward the inside of the slideway 41. At this time, the spiral beryllium copper wire 48 is shortened. When the central axis of the through hole 44 moves to coincide with the central axis of the through hole 44, the upper and lower ends of the through grooves 42 are connected. The oil stored in the storage box 46 flows along the connecting pipe 45 through the through groove 42 and the through hole 44 to the storage box. The storage chamber 32102 does not have excessive oil in it because the conducting hole 44 is narrow and the control rod 47 has a certain rotation speed. When the control rod 47 moves away from the movable column 43, the movable column 43 returns to its original position under the action of the spiral beryllium copper wire 48, and the conducting hole 44 and the conducting groove 42 are offset, thereby blocking the conducting groove 42, and then realizing the function of self-oiling, ensuring that the device can perform self-maintenance, and enhancing the functionality of the device.
