Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic cell production equipment, and in particular to a spray mechanism and a welding ribbon flattening device. Background Art

[0002] A photovoltaic cell string is constructed by stacking and welding together solder ribbons and cells in a predetermined order. Two adjacent cells are connected by a set of solder ribbons. Specifically, the first section of each solder ribbon is soldered to the front busbars of the preceding cell, and the second section is soldered to the back busbars of the following cell. To ensure the solder ribbons adhere to the busbars on the cell surface, the area between the first and second sections is flattened.

[0003] The existing welding strip flattening device includes a driving member, a flattening member and a pressure seat. When the welding strip passes between the flattening member and the pressure seat, the driving member drives the flattening member to move up and down, pressing the welding strip against the pressure seat to flatten the welding strip.

[0004] Since the welding ribbon flattening action is very fast and very frequent, the flattening part will rise and fall and reciprocate at high speed, resulting in a constant friction between the flattening part and the guide component that limits the moving direction of the flattening part. After long-term operation, it is easy to get stuck or reduce the moving accuracy of the flattening part. At present, personnel are generally arranged to disassemble the outer shell of the welding ribbon flattening device on a regular basis every day and drip lubricating oil between the guide component and the flattening part, which has the problem of cumbersome operation.

DETAILED DESCRIPTION

[0048] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0049] In some embodiments, see Figure 1-3 As shown, the present application provides a spray mechanism 10, which includes a base 11 and an atomizing nozzle 12 installed on the base 11. An oil flow channel 13 and an air flow channel 14 are provided in the base 11. The atomizing nozzle 12 includes an oil nozzle 121 and an air nozzle 122 arranged in an inner and outer layer. The oil nozzle 121 is connected to the oil flow channel 13, and the air nozzle 122 is connected to the air flow channel 14.

[0050] By providing an oil channel 13 and an air channel 14 within the base 11 and employing an atomizing nozzle 12 comprising an inner and outer oil nozzle 121 and an air nozzle 122, the oil channel 13 is connected to the oil nozzle 121, and the air channel 14 is connected to the air nozzle 122. While an external liquid supply device introduces lubricating fluid into the oil channel 13 and ejects it from the oil nozzle 121, an external air supply device simultaneously introduces high-pressure gas into the air channel 14 and ejects it from the air nozzle 122. The lubricating fluid ejected from the oil nozzle 121 merges with the high-pressure gas ejected from the air nozzle 122, forming a mist of lubricating fluid, thereby increasing the lubricating fluid's operating area.

[0051] In some embodiments, the base 11 includes a first portion 111 and a second portion 112 that are sealed together. The oil flow channel 13 is disposed in the first portion 111 , and the gas flow channel 14 is disposed between the first portion 111 and the second portion 112 .

[0052] By configuring the base 11 to be divided into the first portion 111 and the second portion 112 , the oil flow channel 13 and the gas flow channel 14 are easily formed on the base 11 .

[0053] Furthermore, the first portion 111 includes a first surface and a raised portion 1111 disposed on the first surface. The first surface is generally rectangular, and the raised portion 1111 is generally rectangular and is disposed in the middle of the first surface. The oil flow channel 13 is disposed within the raised portion 1111, and the oil flow channel 13 extends from one end of the raised portion 1111 to the other opposite end along the length of the base 11. Oil inlets communicating with the oil flow channel 13 are disposed at both ends of the raised portion 1111. When oil needs to be supplied to the oil flow channel 13, an oil inlet pipe 15 can be installed on each oil inlet, so that an external oil supply device can be connected to the oil inlet pipe 15 to provide lubricating oil to the oil flow channel 13.

[0054] Second portion 112 includes a second surface and a groove 1121 defined in the middle of the second surface. The perimeter of the first surface and the perimeter of the second surface are tightly aligned, and a sealing ring is provided between the perimeters of the first and second surfaces. A raised portion 1111 is positioned within groove 1121, and a clearance fit between the outer surface of raised portion 1111 and the walls of groove 1121 forms airflow passage 14.

[0055] One end of the oil nozzle 121 is threadedly connected to the first part 111 and communicates with the oil flow channel 13. The other end of the oil nozzle 121 passes through the flow channel 14 and the second part 112 in sequence and extends to the outside of the second part 112. The air nozzle 122 is sleeved on the oil nozzle 121 and has a clearance fit with the oil nozzle 121. One end of the air nozzle 122 is threadedly connected to the second part 112 and communicates with the flow channel 14. The other end of the air nozzle 122 extends to the outside of the first part 111. The oil outlet end of the oil nozzle 121 is located inside the air nozzle 122. When spraying atomized lubricating oil, the fluid lubricating oil passes through the oil flow channel 13 and is sprayed out of the oil nozzle 121. At the same time, high-pressure gas passes through the flow channel 14 and is sprayed from the gap between the air nozzle 122 and the oil nozzle 121, so that the lubricating oil is atomized and sprayed out from the air outlet end of the air nozzle 122.

[0056] In some embodiments, to enable the spray mechanism 10 to simultaneously operate on different areas, multiple atomizing nozzles 12 are axially symmetrically spaced apart in the middle of the base 11, allowing the atomizing nozzles 12 to operate on different areas and increasing the operating area of ​​the spray mechanism 10. Furthermore, to ensure the spraying distance of the atomizing nozzles 12, a pair of air inlet holes connected to the air flow channel 14 are axially symmetrically disposed at both ends along the length of the base 11. When high-pressure gas is required to be provided to the air flow channel 14, an air inlet pipe 16 can be installed on each air inlet port to connect an external air source to the air inlet pipe 16 to provide high-pressure gas to the air flow channel 14.

[0057] The present application sets a pair of symmetrical air inlet holes at both ends of the base 11, so that the external air source can provide high-pressure gas to the air flow channel 14 at the same time through the pair of air inlet holes, ensuring the air supply of the external air source to the air flow channel 14, so that there is sufficient air pressure in the air flow channel 14, and thus ensuring that the distance for the atomizing nozzle 12 to spray the lubricating liquid meets the requirements.

[0058] In addition, it should be noted that the spray mechanism 10 provided in this application can be applied in a variety of scenarios, as long as there are mechanically connected parts that require regular lubrication, such as sliding screws, slide rails, etc., rotating shafts, spherical bearings, etc. As described below, the spray mechanism 10 of this application is used in a welding ribbon flattening device.

[0059] See also Figure 4-6 As shown, in some embodiments, the present application further provides a solder ribbon flattening device 100, which includes a frame 20, a flattening member 21, a driving mechanism 22, a pressure seat 23, and the aforementioned spray mechanism 10. The driving mechanism 22 is configured to drive the flattening member 21 to move relative to the pressure seat 23 to flatten the solder ribbon to be processed passing between the flattening member 21 and the pressure seat 23.

[0060] The frame 20 is provided with a guide member 24 for guiding the movement of the flattening member 21. The flattening member 21 is inserted into the guide member 24, so that the guide member 24 guides the movement of the flattening member 21. The atomizing nozzle 12 is arranged above the guide member 24 and is located to one side of the flattening member 21. The portion of the flattening member 21 above the guide member 24 is within the spray range of the spray mechanism 10.

[0061] The welding strip flattening device 100 in the present application is provided with a spray mechanism 10, so that the atomizing nozzle 12 of the spray mechanism 10 is provided above the side of the guide component 24 and on the side of the flattening part 21, and the part of the flattening part 21 located above the guide component 24 is located within the spray range of the spray mechanism 10, so that the spray mechanism 10 can spray lubricating oil toward the flattening part 21 through the atomizing nozzle 12 to lubricate the flattening part 21 and the guide component 24, so that the spray mechanism 10 replaces manual lubrication operation between the flattening part 21 and the guide component 24, thereby avoiding long-term friction between the flattening part 21 and the guide component 24, resulting in jamming or reducing the movement accuracy of the flattening part 21.

[0062] In some embodiments, a through hole is provided on the frame 20, and the guide component 24 is a bushing embedded in the through hole, and the flattening member 21 moves up and down in the bushing.

[0063] In other embodiments, the guide member 24 may also be a guide through hole provided in the frame 20 and guiding the upward and downward movement of the flattening member 21 .

[0064] In some embodiments, the ribbon flattening device 100 further includes a dustproof plate 25 mounted on the frame 20. The dustproof plate 25 cooperates with the frame 20 to isolate the flattening member 21 and the guide member 24 from the external environment, thereby preventing external dust from falling onto the flattening member 21 and the guide member 24. The portion of the flattening member 21 located above the guide member 24 is located on the inner side of the dustproof plate 25. The base 11 of the spray mechanism 10 is mounted on the outer side of the dustproof plate 25. The dustproof plate 25 is provided with an avoidance hole 26 for the atomizing nozzle 12 to fit into and point to the portion of the flattening member 21 located above the guide member 24. The atomizing nozzle 12 is at least partially inserted into the avoidance hole 26 and sprays lubricating liquid onto the portion of the flattening member 21 located above the guide member 24.

[0065] See also Figure 6 and Figure 7 As shown, in some embodiments, the ribbon flattening device 100 further includes a return spring 27, which is sleeved on the flattening member 21, and the upper end of the return spring 27 is connected to the top of the flattening member 21 or abuts against the first step surface at the top of the flattening member 21. The lower end of the return spring 27 abuts against the second step surface provided on the frame 20, and the downward pressing surface of the flattening member 21 is lower than the second step surface; alternatively, the lower end of the return spring 27 abuts against the top of the guide member 24.

[0066] At this point, the drive mechanism 22 is configured to drive the flattening member 21 toward the pressure seat 23 to flatten the solder strip to be processed. During this process, the return spring 27 is compressed and deformed. When the drive mechanism 22 removes the driving force, the return spring 27 rebounds and drives the flattening member 21 away from the pressure seat 23, causing the flattening member 21 to return to its original position and prepare to flatten the subsequent solder strip to be processed.

[0067] See also Figure 8 As shown, in some embodiments, a spiral groove 28 extending along the length of the flattening member 21 is formed on the outer wall of the flattening member 21. The spiral groove 28 is located within the spray range of the spray mechanism 10. When the lubricating liquid sprayed by the spray mechanism 10 enters the spiral groove 28, the lubricating liquid can flow downward along the spiral groove 28 around the outer wall of the flattening member 21 and flow between the flattening member 21 and the guide member 24, thereby fully lubricating the flattening member 21 and the guide member 24.

[0068] See also Figure 6 and Figure 7 As shown, in some embodiments, the driving mechanism 22 includes a driving member 221 and a wedge block 222 disposed at the driving end of the driving member 221. The bottom of the wedge block 222 is provided with a downwardly inclined inclined surface 2221. A roller is rotatably mounted on the flattening member 21 via a mounting block 3029. The roller abuts against the inclined surface 2221. The driving member 221 drives the wedge block 222 to move horizontally, causing the roller to roll along the inclined surface 2221, thereby moving the flattening member 21 downward toward the pressure seat 23 to flatten the solder ribbon to be processed.

[0069] A limiting wheel 40 is rotatably connected to the frame 20. The wedge block 222 has a horizontally disposed upper surface, and the bottom of the limiting wheel 40 abuts against the upper surface of the wedge block 222. When the driving member 221 drives the wedge block 222 to move horizontally, the limiting wheel 40 rolls along the upper surface of the wedge block 222 to limit the upper limit of the wedge block 222, preventing the wedge block 222 from deviating upward during movement.

[0070] Furthermore, to facilitate assembly and disassembly between the mounting block 3029 and the roller shaft, a pair of shaft slots 31 opening toward the roller shaft are provided at the top of the mounting block 3029. The roller shaft comprises a roller body positioned between the pair of shaft slots 31 and a pair of shaft rods at either end of the roller body, each of which is inserted into the pair of shaft slots 31.

[0071] See also Figure 8 As shown, in some embodiments, the flattening member 21 includes a lifting rod 211 and a pressing head 212. The lifting rod 211 is disposed within the guide member 24, the mounting block 3029 is disposed at the first end of the lifting rod 211, and the pressing head 212 is disposed at the second end of the lifting rod 211. A return spring 27 is sleeved on the lifting rod 211, and the lifting rod 211 extends through the guide member 24. The pressing head 212 has a lower pressing surface at one end away from the lifting rod 211 that cooperates with the pressure seat 23 to flatten the solder ribbon to be processed.

[0072] The lifting rod 211 and the pressure head 212 are detachably connected, making it easy to remove the pressure head 212 from the lifting rod 211 and replace it after it is worn. Specifically, a locking portion 2121 is provided at the top of the pressure head 212, the width of which gradually increases from bottom to top. A limiting opening 2111 is provided at the bottom of the lifting rod 211, which matches the shape of the locking portion 2121. The locking portion 2121 can be inserted into the limiting opening 2111 in the horizontal direction. A limiting sleeve 32 is provided on the lifting rod 211, and the limiting sleeve 32 is configured to be mounted on the locking portion 2121 and the limiting opening 2111 to prevent relative sliding after the two are connected.

[0073] In some embodiments, the portion of the lifting rod 211 below the guide member 24 is provided with a vertically extending elongated stop hole 33. A stop post 34 is fixedly mounted on the frame 20 and extends through the elongated stop hole 33. As the lifting rod 211 is raised or lowered, the stop post 34 moves relative to the elongated stop hole 33. The stop post 34 limits the vertical movement of the lifting rod 211, preventing the lifting rod 211 from exceeding a set range of vertical movement.

[0074] In some embodiments, the ribbon flattening device 100 can simultaneously flatten multiple ribbons to be processed. In this case, the frame 20 is provided with multiple flattening members 21 spaced apart horizontally. Drivers 221 are provided in a one-to-one correspondence with the flattening members 21, with adjacent drivers 221 staggered on either side of the frame 20. Drivers 221 can optionally be pneumatic or electric cylinders.

[0075] See also Figure 5 As shown, in some embodiments, the solder strip flattening device 100 further includes a positioning assembly and a solder strip guiding assembly, which are sequentially arranged behind the flattening member 21 along the pulling direction of the solder strip to be processed.

[0076] The welding ribbon guide assemblies correspond to the flattening members 21 one by one, and each welding ribbon guide assembly includes two guide posts 35 arranged in pairs, with a guide gap formed between the two guide posts 35 for the welding ribbon to pass through. The welding ribbon passes through the guide gap, guiding the traction of the welding ribbon.

[0077] The positioning assembly includes a lifting plate 36, a positioning block 37, a base 38, and a lifting drive 39. The lifting plate 36 is positioned behind the flattening member 21, along the direction in which the processed solder strip is pulled. Two lifting drives 39 are provided, each fixedly mounted on the frame 20, with their drive ends connected to the ends of the lifting plate 36. Positioning blocks 37 are fixedly mounted on the lifting plate 36 and positioned above the processed solder strip, corresponding one-to-one with the flattening member 21. Base 38 corresponds one-to-one with positioning blocks 37 and is fixedly mounted on the frame 20 and positioned below the processed solder strip. When the processed solder strip is pulled between the flattening member 21 and the pressure seat 23 and before being flattened, the lifting drive 39, via the lifting plate 36, drives the positioning blocks 37 downward, pressing the corresponding processed solder strip against the base 38 to prevent the solder strip from shaking when the flattening member 21 flattens the designated portion of the solder strip. Optionally, the lifting drive device 39 is a cylinder.
