Description

Technical Field

[0001] The present application relates to the technical field of cutting devices, and in particular to a device for cutting welding strips after string welding of solar silicon wafers. Background Art

[0002] After the silicon wafers are welded, the welding ribbon (thin copper ribbon) needs to be cut into pieces to achieve the function of having the head and tail welding ribbons (thin copper ribbons) of the silicon wafers after string welding. Its specific structure includes a base, a transport platform installed on the base for transporting the cut welding ribbon, a gantry installed on the base, and a rectangular cutting blade installed on the gantry that can move up and down.

[0003] The existing technology has a long blade head for the entire cutting surface, which cuts the welded solder strip (thin copper strip) by up and down movements. However, due to the influence of high-temperature welding in the production process and the influence of long-term wear, the flatness will deteriorate over time, resulting in the solder strip (thin copper strip) in the concave flatness being cut off when the blade falls down for cutting, and the solder strip (thin copper strip) in the blunt edge being cut off, resulting in poor cutting consistency, which will increase the number of times the blade head needs to be sharpened, polished, and leveled, and the number of times the base plate needs to be repaired and polished, affecting production efficiency and product stability. Therefore, a device for cutting the solder strip after solar silicon wafer string welding is needed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a device for cutting the welding strips after the solar silicon wafers are string welded, which is used to solve the technical problem in the existing technology that the production efficiency and product stability are reduced due to the wear of the long blade head.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: A device for cutting the welding strips after string welding of solar silicon wafers, comprising a base, a transport platform installed on the base for transporting the cut welding strips, a pair of support rods installed on the base, a driving device installed on the pair of support rods, and a knife seat installed on the output end of the driving device, the knife seat comprising a fixed seat installed on the output end of the driving device, a sliding seat slidably connected to the fixed seat, a fixed plate fixedly connected to the sliding seat, a cutting blade rotatably connected to the fixed plate, and a support spring fixedly arranged on the fixed seat for sliding downward against the sliding seat, one end of the support spring is fixedly connected to the fixed seat, and the other end is fixedly connected to the sliding seat, the cutting blade is circular, a cutting groove for the moving cutting of the cutting blade is provided on the transport platform, a gap is left between the pair of support rods, and the driving device is located between the pair of support rods.

[0006] Furthermore, the driving device includes a fixed bracket fixed on the support rod, a notched boss fixed on the left and right ends of the fixed bracket, a wheel rotatably set in the notched boss, a conveyor belt with two ends respectively sleeved on the two wheels, and a driving motor fixed on the fixed bracket with an output end fixedly connected to one of the two wheels, and the fixed seat is fixed on the conveyor belt.

[0007] The blade is then moved back and forth to move the cutting blade in a direction of rotation relative to the cutting edge, thereby reducing the risk of scraping and scraping.

[0008] Furthermore, a plurality of elastic gaskets are fixedly provided on the bottom surface of the cutting groove and arranged along the length direction of the cutting groove, and the elastic gaskets are made of elastic material.

[0009] By adopting the above technical solution, although the setting of the support spring improves the consistency of the cutting blade in cutting the welding strip, when the cutting blade rolls in the cutting groove, since the transport platform is made of rigid material, this causes the cutting blade to break each time it rolls in the cutting groove due to the pressure of the support spring. The setting of the elastic gasket solves this technical problem. Through the setting of the elastic gasket, the cutting blade has a certain amount of movement margin after being subjected to the pressure of the support spring during rolling, and the rigid contact between the cutting blade and the transport platform is reduced, thereby reducing the wear on the cutter head and improving the cutting stability.

[0010] Furthermore, an adjustment device is provided on both sides of the elastic gasket and is installed on the transport platform for adjusting the position of the elastic gasket. The adjustment device includes a moving rod passing through multiple elastic gaskets, a moving plate fixedly arranged on both sides of the moving rod, and an output electric cylinder installed on both sides of the transport platform and fixedly connected to the moving plate at the output end.

[0011] By adopting the above technical solution, although the setting of the elastic gasket can reduce the rigid contact between the cutting blade and the transport platform, reduce the wear on the cutter head, and improve the cutting stability, the cutting blade needs to cut the welding strip for a long time, which causes the cutting blade to contact the elastic gasket for a long time, making the position where the elastic gasket often contacts the cutting blade easy to lose its own elasticity, thereby reducing the service life of the elastic gasket. The setting of the adjustment device solves this technical problem. After the cutting blade has worked for a period of time, by starting the output electric cylinder, the output end of the output electric cylinder is extended or contracted to drive multiple elastic gaskets to move back and forth in the cutting groove through the moving plate and the moving rod, changing the position where the elastic gasket contacts the cutting blade, so that the other parts of the elastic gasket slowly recover their elasticity, thereby improving the service life of the elastic gasket.

[0012] Furthermore, a protective cover is provided on one side of the fixed plate away from the sliding seat. The protective cover is fixedly arranged on the fixed plate to cover the cutting blade, and the bottom surface of the cutting blade extends out of the protective cover.

[0013] By adopting the above technical solution, the cutting blade is further protected and prevented from being damaged.

[0014] Furthermore, visual lenses are fixedly provided on the left and right sides of the protective cover, and the visual lens signals are connected to a detection system.

[0015] Furthermore, the detection system includes a storage module for storing graphic data after the welding strip is cut, a comparison module for comparing the image signal of the visual lens with the graphic data in the storage module after receiving the image signal, and an alarm device for being activated after receiving the start signal of the comparison module. After the comparison module receives the image signal of the visual lens and compares it with the graphic data in the storage module, if the image signal of the visual lens is consistent with the graphic data in the storage module, the start signal will not be sent to the alarm device; if the image signal of the visual lens is inconsistent with the graphic data in the storage module, the start signal will be sent to the alarm device.

[0016] By adopting the above technical solution, when the cutting blade is cutting, the visual lens will send the image signal after the cutting blade cuts to the comparison module. After receiving the image signal from the visual lens, the comparison module will compare it with the graphic data in the storage module. If the image signal from the visual lens is inconsistent with the graphic data in the storage module, a start signal will be sent to the alarm device. The alarm device will sound an alarm to remind the operator that the welding strip is not cut completely, so that the staff can discover the failure of the cutting device earlier.

[0017] Furthermore, the driving device includes a first fixed frame fixed on the support rod, a sliding groove opened along the length direction of the fixed frame, and a first linear motor slidably connected to the first fixed frame through the sliding groove. A roller is fixed at the output end of the linear motor, and the roller is located in the sliding groove. The tool holder is fixed on the linear motor.

[0018] By adopting the above technical solution, the first linear motor is started to rotate the roller, driving the first linear motor to slide along the sliding groove, so that the tool holder moves left and right between a pair of support rods.

[0019] Furthermore, the driving device includes a second fixing frame fixedly arranged on the support rod, cylinders installed on both sides of the second fixing frame, and a pneumatic block slidably connected to the second fixing frame, and the tool holder is fixedly arranged on the pneumatic block.

[0020] By adopting the above technical solution, the cylinders on both sides of the second fixed frame are started to blow air to the pneumatic block, so that the pneumatic block slides left and right on the second fixed frame, thereby causing the tool holder to move left and right between a pair of support rods.

[0021] Furthermore, the driving device includes a third fixed frame fixedly mounted on the support rod, fixed plates installed at both ends of the third fixed frame, a screw rod passing through the two fixed plates in sequence and rotatably connected to the fixed plates, a fixed motor fixedly mounted on the third fixed frame and fixedly connected to the screw rod at the output end, and a threaded slider threadedly connected to the screw rod, and the tool holder is fixedly mounted on the threaded slider.

[0022] By adopting the above technical solution, the fixed motor is started to rotate the screw rod, and the rotating screw rod causes the threaded slider to move along the thread of the screw rod, thereby causing the tool holder to move left and right between a pair of support rods.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the arrangement of the driving device, the knife seat and the circular cutting blade, the welding strip is placed on the transport platform through the cutting groove, and the driving motor is started forward and reversed at the same time to rotate the wheel and drive the fixed seat to move left and right along the fixed bracket, thereby driving the cutting blade to move left and right in the cutting groove to cut the welding strip. The sliding seat is pressed by the supporting spring so that the sliding seat drives the cutting blade to move downward. When the cutting blade cuts the welding strip, the supporting spring provides supporting force to the cutting blade so that the cutting pressure is evenly released on the welding strip to be cut, significantly improving the consistency of the cutting of the welding strip by the cutting blade, and will not affect the cutting yield due to wear of a certain section of the cutting blade, and does not require frequent sharpening. The supporting spring provides supporting force to the cutting blade, so that the cutting blade rotates passively rather than actively when cutting, reducing the waste generated by the cutting blade when cutting the welding strip and maintaining the cleanliness of the entire cutting device.

[0025] 2. By setting the elastic gasket, the cutting blade has a certain amount of movement margin after being subjected to the pressure of the support spring when rolling, and the rigid contact between the cutting blade and the transport platform is reduced, thereby reducing the wear on the cutter head and improving the cutting stability.

[0026] 3. By adjusting the settings of the device, it is achieved that after the cutting blade has worked for a period of time, by starting the output electric cylinder, the output end of the output electric cylinder is extended or contracted, and the multiple elastic gaskets are driven to move back and forth in the cutting groove through the moving plate and the moving rod, thereby changing the position where the elastic gasket contacts the cutting blade, so that the other parts of the elastic gasket slowly recover their elasticity, thereby improving the service life of the elastic gasket.

[0027] 4. Through the setting of the visual lens and the detection system, it is achieved that when the cutting blade is cutting, the visual lens will send the image signal after the cutting blade is cutting to the comparison module. After receiving the image signal of the visual lens, the comparison module will compare it with the graphic data in the storage module. If the image signal of the visual lens is inconsistent with the graphic data in the storage module, a start signal will be sent to the alarm device. The alarm device will sound an alarm to remind the operator that the welding strip is not cut completely, so that the staff can discover the fault of the cutting device earlier.

DETAILED DESCRIPTION

[0036] The present application is further described in detail below with reference to the accompanying drawings.

[0037] Example 1, with reference to Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4A device for cutting the welding ribbon after string welding of solar silicon wafers includes a base 1, a transport platform 10 installed on the base 1 for transporting the cut welding ribbon, a pair of support rods 11 installed on the base 1, a driving device 3 installed on the pair of support rods 11, and a knife seat 2 installed on the output end of the driving device 3. The knife seat 2 includes a fixed seat 20 installed on the output end of the driving device 3, a sliding seat 21 connected to the fixed seat 20 for sliding up and down, a fixed plate 22 fixedly connected to the sliding seat 21, and a cutting blade 23 rotatably connected to the fixed plate 22, and a fixed seat 20 for pressing the sliding seat 21 downward. The sliding support spring 24 has one end fixedly connected to the fixed seat 20 and the other end fixedly connected to the sliding seat 21. The cutting blade 23 is circular. A cutting groove 100 for the moving cutting of the cutting blade 23 is provided on the transport platform 10. A gap is left between the pair of support rods 11, and the driving device 3 is located between the pair of support rods 11. The driving device 3 is fixedly provided on the fixed bracket 30 on the support rod 11, the notched boss 31 fixedly provided on the left and right ends of the fixed bracket 30, the rotating wheel 32 rotatably provided in the notched boss 31, the conveyor belt 33 respectively sleeved on the two wheels 32 at both ends, and the fixed The output end of the fixed bracket 30 is fixedly connected to the driving motor 34 of one of the two rotating wheels 32. The fixed base 20 is fixedly set on the conveyor belt 33. The welding strip passes through the cutting groove 100 and is placed on the transport platform 10. At the same time, the driving motor 34 is started to rotate forward and reversely so that the rotating wheel 32 rotates and drives the fixed base 20 to move left and right along the fixed bracket 30, thereby driving the cutting blade 23 to move left and right in the cutting groove 100 to cut the welding strip. The support spring 24 applies pressure to the sliding base 21 so that the sliding base 21 drives the cutting blade 23 to move downward. When the cutting blade 23 cuts the welding strip, the support spring 24 will provide the cutting blade 23 with pressure. The supporting force allows the cutting pressure to be evenly released on the welding strip to be cut, significantly improving the consistency of the cutting of the welding strip by the cutting blade 23. The cutting yield will not be affected by the wear of a certain section of the cutting blade 23, and there is no need for frequent sharpening. The supporting force is provided to the cutting blade 23 by the supporting spring 24, so that the cutting blade 23 rotates passively rather than actively during cutting. The actively rotating cutting blade 23 will cause the circular surface of the cutting blade 23 to continuously rub the welding strip and produce excess waste chips, while the passively rotating cutting blade 23 will not, which reduces the waste chips generated by the cutting blade 23 when cutting the welding strip and maintains the cleanliness of the entire cutting device.

[0038] Although the setting of the support spring 24 improves the consistency of the cutting of the welding strip by the cutting blade 23, when the cutting blade 23 rolls in the cutting groove 100, since the transport platform 10 is made of rigid material, this may cause the cutting blade 23 to break each time it rolls in the cutting groove 100 due to the pressure of the support spring 24. In order to solve this technical problem, this embodiment has an elastic gasket 4 fixedly provided on the bottom surface of the cutting groove 100, which is covered with cutting grooves 100. The elastic gasket 4 is made of elastic material. Through the setting of the elastic gasket 4, the cutting blade 23 has a certain amount of movement margin after being subjected to the pressure of the support spring 24 when rolling, and the rigid contact between the cutting blade 23 and the transport platform 10 is reduced, thereby reducing the wear on the cutter head and improving the cutting stability.

[0039] Although the setting of the elastic gasket 4 can reduce the rigid contact between the cutting blade 23 and the transport platform 10, reduce the wear on the cutter head, and improve the cutting stability, the cutting blade 23 needs to cut the welding strip for a long time, which causes the cutting blade 23 to need to contact the elastic gasket 4 for a long time, making the position where the elastic gasket 4 often contacts the cutting blade 23 easy to lose its own elasticity, reducing the service life of the elastic gasket 4. In order to solve this technical problem, the present embodiment is provided with an adjustment device 5 installed on the transport platform 10 on both sides of the elastic gasket 4 for adjusting the position of the elastic gasket 4. The adjustment device 5 includes a through A moving rod 50 with multiple elastic gaskets 4, a moving plate 51 fixedly arranged on both sides of the moving rod 50, and an output electric cylinder 52 installed on both sides of the transport platform 10 with the output end fixedly connected to the moving plate 51. When the cutting blade 23 has been working for a period of time, the output electric cylinder 52 is started so that the output end of the output electric cylinder 52 extends or contracts to drive the multiple elastic gaskets 4 to move back and forth in the cutting groove 100 through the moving plate 51 and the moving rod 50, changing the position where the elastic gasket 4 contacts the cutting blade 23, so that the other parts of the elastic gasket 4 slowly recover their elasticity, thereby improving the service life of the elastic gasket 4.

[0040] In this embodiment, a protective cover 25 is provided on the side of the fixed plate 22 away from the sliding seat 21. The protective cover 25 is fixedly set on the fixed plate 22 to cover the cutting blade 23. The bottom surface of the cutting blade 23 extends out of the protective cover 25, further protecting the cutting blade 23 and preventing it from being damaged.

[0041] In this embodiment, visual lenses 26 are fixedly provided on the left and right sides of the protective cover 25. The visual lenses 26 are signal-connected to a detection system. The detection system includes a storage module for storing graphic data after the welding ribbon is cut, a comparison module for receiving the image signal of the visual lens 26 and comparing it with the graphic data in the storage module, and an alarm device for receiving a start signal from the comparison module and starting it. After the comparison module receives the image signal of the visual lens 26 and compares it with the graphic data in the storage module, if the image signal of the visual lens 26 is consistent with the graphic data in the storage module, no start signal is sent to the alarm device. If the image signal of the visual lens 26 is inconsistent with the graphic data in the storage module, a start signal is sent to the alarm device. When the cutting blade 23 is cutting, the visual lens 26 sends the image signal after the cutting blade 23 is cutting to the comparison module. After receiving the image signal of the visual lens 26, the comparison module compares it with the graphic data in the storage module. If the image signal of the visual lens 26 is inconsistent with the graphic data in the storage module, a start signal is sent to the alarm device. The alarm device issues an alarm to remind the operator that the welding ribbon is not cut completely, so that the operator can discover the fault of the cutting device earlier.

[0042] Example 2, reference Figure 5 The difference between this embodiment and embodiment 1 is that: the driving device 3 includes a first fixed frame 300 fixedly set on the support rod 11, a sliding groove 301 opened along the length direction of the fixed frame, and a first linear motor 302 slidably connected to the first fixed frame 300 through the sliding groove 301. A roller is fixedly provided at the output end of the linear motor, and the roller is located in the sliding groove 301. The tool holder 2 is fixed on the linear motor. By starting the first linear motor 302, the roller rotates, driving the first linear motor 302 to slide along the sliding groove 301, so that the tool holder 2 moves horizontally left and right between a pair of support rods 11.

[0043] Example 3, reference Figure 6 The difference between this embodiment and Embodiment 1 and Embodiment 2 is that: the driving device 3 includes a second fixing frame 310 fixedly set on the support rod 11, cylinders 311 installed on both sides of the second fixing frame 310, and a pneumatic block 312 slidably connected to the second fixing frame 310, and the tool holder 2 is fixedly set on the pneumatic block 312. By starting the cylinders 311 on both sides of the second fixing frame 310 to blow air to the pneumatic block 312, the pneumatic block 312 slides left and right on the second fixing frame 310, thereby causing the tool holder 2 to move left and right between a pair of support rods 11.

[0044] Example 4, with reference to Figure 7The difference between this embodiment and embodiment 1, embodiment 2 and embodiment 3 is that: the driving device 3 includes a third fixing frame 320 fixedly set on the support rod 11, fixing plates 321 installed at both ends of the third fixing frame 320, a screw rod 322 passing through the two fixing plates 321 in sequence and rotatably connected to the fixing plates 321, a fixed motor 323 fixedly installed on the third fixing frame 320 and fixedly connected to the screw rod 322 at the output end, and a threaded slider 324 threadedly connected to the screw rod 322, and the tool holder 2 is fixedly set on the threaded slider 324. By starting the fixed motor 323, the screw rod 322 is rotated, and the rotating screw rod 322 causes the threaded slider 324 to move along the thread of the screw rod 322, thereby causing the tool holder 2 to move horizontally left and right between a pair of support rods 11.

[0045] Specific implementation process: Place the welding ribbon through the cutting groove 100 on the transport platform 10, and start the driving motor 34 to rotate forward and reverse at the same time to make the rotating wheel 32 rotate and drive the fixing seat 20 to move left and right along the fixing bracket 30, thereby driving the cutting blade 23 to move left and right in the cutting groove 100 to cut the welding ribbon, and apply pressure to the sliding seat 21 through the support spring 24, so that the sliding seat 21 drives the cutting blade 23 to move downward. When the cutting blade 23 cuts the welding ribbon, the support spring 24 will provide support force to the cutting blade 23, so that the cutting pressure is evenly released on the welding ribbon to be cut. While cutting, the cutting blade 23 rolls on the elastic pad, and the wear of the cutting blade 23 is reduced by the elastic pad 4. When the cutting blade 23 is cutting, the visual lens 26 The image signal after cutting by the cutting blade 23 will be sent to the comparison module. After receiving the image signal of the visual lens 26, the comparison module will compare it with the graphic data in the storage module. If the image signal of the visual lens 26 is inconsistent with the graphic data in the storage module, a start signal will be sent to the alarm device. The alarm device will alarm to remind the operator that the welding strip cutting is incomplete, so that the staff can discover the failure of the cutting device earlier. When it is necessary to change the position of the elastic gasket 4 contacting the cutting blade 23, the output electric cylinder 52 is started to extend or contract the output end of the output electric cylinder 52 to drive multiple elastic gaskets 4 to move back and forth in the cutting groove 100 through the movable plate 51 and the movable rod 50, thereby changing the position of the elastic gasket 4 contacting the cutting blade 23.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
