Description

Technical Field

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

[0002] Photovoltaic welding ribbon, also known as tin-coated copper ribbon, is a conductive lead ribbon for solar cells. It is used to connect the cells of photovoltaic modules and plays an important role in conducting electricity. The production process of photovoltaic welding ribbon is generally divided into steps such as material preparation, coating, cutting, winding and packaging.

[0003] At present, photovoltaic welding strips are cut by a slitting device, which includes two slitting tools facing each other, and the slitting tools include a rotating shaft and a plurality of slitting blades fixed on the rotating shaft, and the slitting blades of the two slitting tools correspond to each other. When in use, the photovoltaic welding strip is placed between the two slitting tools, and the rotating shafts of the two slitting tools are rotated to make the slitting blades roll relative to the photovoltaic welding strip, and the slitting blades cut the photovoltaic welding strip into long strips.

[0004] Although the above solution realizes the slitting of photovoltaic welding ribbons, it is difficult to slit photovoltaic welding ribbons of different widths, thereby reducing the flexibility of photovoltaic welding ribbon processing. Summary of the invention

[0005] In order to be able to cut out photovoltaic welding ribbons of different widths, the present application provides a photovoltaic welding ribbon cutting device.

[0006] The present application provides a photovoltaic ribbon slitting device, which adopts the following technical solution:

[0007] A photovoltaic ribbon slitting device, comprising:

[0008] Cutting knife holder;

[0009] The first cutting assembly comprises a cutting shaft and a cutting blade;

[0010] A second cutter assembly having the same structure as the first cutter assembly;

[0011] The adjusting assembly is provided with two groups and is respectively provided on the first cutter assembly and the second cutter assembly, and the adjusting assembly comprises an electromagnet, a clamping rod, a chain ring and an adjusting part;

[0012] in,

[0013] Both ends of the cutter shaft are coaxially fixed with a turntable, which is rotatably connected to the cutter frame. A plurality of cutter blades are provided, and are coaxially slidably sleeved on the cutter shaft, and the sliding direction of the cutter blades is the axial direction of the cutter shaft.

[0014] The cutting blades of the second cutting blade assembly correspond to and abut against the cutting blades of the first cutting blade assembly one by one;

[0015] There are multiple groups of electromagnets, and they are respectively located between two adjacent cutting blades. Each group of electromagnets has two electromagnets, and they are respectively and symmetrically fixed on the sides of the two adjacent cutting blades close to each other.

[0016] Two adjustment holes are symmetrically provided on the cutting blade and the rotating disk, a plurality of clamping rods are provided, and they correspond to the adjustment holes one by one, and the clamping rods are fixed in the adjustment holes and are located at the end of the adjustment holes away from the cutting blade shaft;

[0017] The chain ring is slidably arranged in all the adjustment holes, and the sliding direction of the chain ring is the direction approaching or moving away from the axis of the cutter shaft;

[0018] Two adjusting parts are symmetrically arranged and respectively arranged on the sides of the two rotating disks away from each other. The adjusting parts support the chain ring in a rectangular shape and are used to adjust the width of the chain ring so that the clamping rod can be inserted into or out of the chain hole of the chain ring.

[0019] By adopting the above technical scheme, the width of the chain ring is adjusted by the adjustment part to reduce the width of the chain ring and increase the length of the chain ring, so that the clamping rod can be disengaged from the chain hole of the chain ring, so that the cutting blade can slide relative to the cutting blade shaft, and the electromagnet is energized. The energized electromagnet drives the cutting blade to slide by magnetic force to adjust the distance between two adjacent cutting blades. Under the joint action of all electromagnets, all cutting blades are adjusted to the same distance, and then the width of the chain ring is increased by adjusting the adjustment part, so that the clamping rod is re-clamped into the chain hole of the chain ring to fix the cutting blade and the cutting blade to the cutting blade shaft. By rotating the turntable, the cutting blade can cut the photovoltaic welding strip, so that by changing the distance between two adjacent cutting blades, photovoltaic welding strips of different widths can be cut, thereby improving the flexibility of photovoltaic welding strip processing.

[0020] Optionally, the adjustment unit includes:

[0021] The adjusting oil cylinder is fixed on the turntable, and the extension direction is consistent with the axial direction of the cutter shaft, and the movable end of the adjusting oil cylinder is located at the end away from the turntable;

[0022] The middle part of the two-way telescopic rod is fixed on the movable end of the adjusting oil cylinder, and the two movable ends of the two-way telescopic rod are slidably connected with the inner side of the chain ring;

[0023] The adjusting spring is arranged between the two movable ends of the bidirectional telescopic rod and is used for driving the two movable ends of the bidirectional telescopic rod to extend synchronously.

[0024] By adopting the above technical solution, when the adjusting cylinder extends, the adjusting cylinder pushes the two-way telescopic rod away from the turntable. Since the circumference of the chain ring is fixed, the chain ring can squeeze the two active ends of the two-way telescopic rod to shrink synchronously, so that the width of the chain ring is reduced; when the adjusting cylinder shrinks, the adjusting cylinder pulls the two-way telescopic rod close to the turntable, and the adjusting spring drives the two active ends of the two-way telescopic rod to extend synchronously, so that the width of the chain ring increases, thereby making the width of the chain ring easy to adjust.

[0025] Optionally, both movable ends of the bidirectional telescopic rod are rotatably connected to sprockets, and the sprockets are meshed with chain rings.

[0026] By adopting the above technical solution, the movable end of the two-way telescopic rod is slidably connected to the chain ring through the sprocket, which on the one hand makes the chain ring less susceptible to wear, and on the other hand makes the sliding of the chain ring and the movable end of the two-way telescopic rod stable.

[0027] Optionally, the cutter shaft is hollow inside, a sliding hole penetrating the cutter shaft is provided on the cutter shaft, a sliding plate is fixedly connected to the cutting blade, the sliding plate is slidably arranged in the sliding hole, a damping assembly is arranged in the cutter shaft, and the damping assembly includes a damping oil cylinder, a damping capillary, a sliding rod and a damping plate;

[0028] A plurality of damping oil cylinders are provided, and correspond to the cutting blades one by one, and the damping oil cylinders are fixed on the slide plate;

[0029] A plurality of damping capillaries are provided, and correspond to the damping oil cylinders one by one. One end of the damping capillary is connected to the rodless chamber of the damping oil cylinder, and the other end is connected to the rod chamber of the damping oil cylinder. Hydraulic oil flows through the rodless chamber and the rod chamber of the damping oil cylinder through the damping capillary.

[0030] There are multiple sliding rods, which correspond to the damping oil cylinders one by one, and the sliding rods are fixedly connected to the movable ends of the damping oil cylinders;

[0031] The damping plate is fixed in the cutter shaft and arranged along the sliding direction of the slide plate. A damping groove is opened on one side of the damping plate close to the damping cylinder along the sliding direction of the slide plate. The damping groove is wavy, and one end of the slide rod is slidably arranged in the damping groove.

[0032] By adopting the above technical scheme, the damping cylinder follows the sliding of the cutting blade through the slide plate, and the damping cylinder drives the slide rod to slide in the wavy damping groove. The wavy damping groove drives the damping cylinder to extend and retract through the slide rod. During the extension and retraction process, the damping cylinder can drive the hydraulic oil in its own rodless chamber and rod chamber to flow through the damping capillary. When the hydraulic oil flows in the damping capillary, it can generate a damping force on the extension and retraction of the damping cylinder, so that the cutting blade can slide slowly, making the adjusted distance between the cutting blades easy to control.

[0033] Optionally, the damping capillary is slidably arranged on the turntable, and a switch valve is arranged on a portion of the damping capillary outside the cutter shaft.

[0034] By adopting the above technical scheme, when the switch valve is closed, it is difficult for hydraulic oil to flow between the rodless chamber and the rod chamber of the damping cylinder, so that the movable end of the damping cylinder is in a fixed state. Since the sliding rod slides in the wavy damping groove, when the movable end of the damping cylinder is fixed, it is difficult for the sliding rod to slide relative to the damping plate, so that a single cutting blade can be fixed to the cutting blade shaft, so that the distance value between two adjacent cutting blades can be different, and then by individually fixing each cutting blade, photovoltaic welding strips of different widths can be cut out at the same time.

[0035] Optionally, a display component is provided between two adjacent cutting blades, and the display component is used to display the distance between the two adjacent cutting blades.

[0036] By adopting the above technical solution, the user can directly observe the adjustment status of the distance between the two cutting blades through the display component, thereby improving the adjustment efficiency of the cutting blades.

[0037] Optionally, the display component includes:

[0038] A display box is fixed on one of the cutting blades;

[0041] A display spring is arranged in the display box and is located at a side of the display panel away from the pull rope. The display spring is used to drive the display panel to pull the pull rope to slide into the display box;

[0042] A transparent display tube is fixedly mounted on another cutting blade, one end of the transparent display tube is open, and the other end is sealed. The sealed end of the transparent display tube is connected to an end of the display box away from the display spring through a hose, and a colored liquid flows between the transparent display tube and the display box through the hose.

[0043] An indicator panel is slidably disposed in the transparent display tube;

[0044] An air hole is provided at one end of the display box close to the display spring, and sealing and sliding are provided between the display panel and the display box, between the pull rope and the display box, and between the indicator panel and the transparent display tube.

[0045] By adopting the above technical solution, when two adjacent cutting blades move away from each other, the pull rope slides out of the display box, and pulls the display board to squeeze the fluid medium into the transparent display tube, and the fluid medium drives the indicator plate to slide toward the open end of the transparent display tube; when two adjacent cutting blades approach each other, the display spring pulls the pull rope through the display board to slide into the display box, the display board sucks the fluid medium from the transparent display tube into the display box, and the fluid medium drives the indicator plate to slide toward the sealed end of the transparent display tube, so that the distance between the two cutting blades can be intuitively displayed through the position of the indicator plate.

[0046] Optionally, a scale is provided on the outer wall of the transparent display tube.

[0047] By adopting the above technical solution, the distance value between the two cutting blades can be directly and accurately known through the scale on the transparent display tube, so that the distance between the two cutting blades can be adjusted more accurately.

[0048] Optionally, a limiting plate is fixedly provided on the inner wall of the transparent display tube, and the limiting plate is arranged close to the opening end of the transparent display tube.

[0049] By adopting the above technical solution and providing the limiting plate, the indicating plate is not easy to slide out of the transparent display tube, and the fluid medium is not easy to flow out of the transparent display tube.

[0050] Optionally, a drive assembly is provided on the cutter frame, and the drive assembly is located at one end of the cutter shaft. The drive assembly includes a motor, a gear and a gear ring. The motor is fixedly connected to the cutter frame, and the gear is coaxially fixedly connected to the output shaft of the motor. Two gear rings are provided and are coaxially fixedly connected to the turntable of the first cutter assembly and the turntable of the second cutter assembly, respectively. The gear is meshed with one of the gear rings, and both gear rings are meshed.

[0051] By adopting the above technical solution, the motor drives one of the gear rings to rotate through the gear, and one of the gear rings drives the other gear ring to rotate, so that the first cutter assembly and the second cutter assembly can rotate synchronously in opposite directions.

[0077] When in use, start the adjusting cylinder 441, which drives the two-way telescopic rod 442 away from the turntable 211, and the chain ring 43 with a fixed circumference squeezes the two movable ends of the two-way telescopic rod 442 to shrink synchronously, so that the clamping rod 42 escapes from the chain hole of the chain ring 43 to release the fixation of the cutting blade 22 and the cutting shaft 21; adjust the polarity of the two symmetrical electromagnets 41 to make the two adjacent cutting blades 22 move away from or approach each other, so as to achieve equal distance adjustment of the slitting width of the photovoltaic welding strip; make the adjusting cylinder 441 drive the two-way telescopic rod 442 to approach the turntable 211, and the two-way telescopic rod 442 extends synchronously under the elastic force of the adjusting spring 443, so that the clamping rod 42 is inserted into the chain hole of the chain ring 43 to fix the cutting blade 22 and the cutting shaft 21.

[0078] Start the motor 71, the motor 71 drives the gear 72 to rotate, the gear 72 drives the ring gear 73 to rotate, and the ring gear 73 drives another ring gear 73 to rotate, so that the cutting blade 22 of the first cutting knife assembly 2 and the cutting blade 22 of the second cutting knife assembly 3 rotate synchronously in opposite directions, and the photovoltaic welding strip is placed between the cutting blade 22 of the first cutting knife assembly 2 and the cutting blade 22 of the second cutting knife assembly 3, thereby realizing the slitting of the photovoltaic welding strip, so that photovoltaic welding strips of different widths can be slit.

[0082] Close the switch valve 521 to block the flow of hydraulic oil in the damping capillary 52, making it difficult for the damping cylinder 51 to extend or retract, so that the cutting blade 22 and the cutting shaft 21 can be fixed separately, so that the distance values ​​of two adjacent cutting blades 22 can be different.

The colored liquid pushes the indicator plate 66 to slide close to the limit plate 67. The indicator plate 66 displays the distance value between the two adjacent cutting blades 22 through the scale 652 on the transparent display tube 65.

[0091] When the adjustment distance between two adjacent cutting blades 22 is reduced, the display spring 64 drives the pull rope 63 to slide into the display box 61 through the display panel 62, and the display panel 62 draws the colored liquid back into the display box 61. The colored liquid drives the indicator plate 66 to slide away from the limit plate 67. The indicator plate 66 displays the distance value between the two adjacent cutting blades 22 through the scale 652 on the transparent display tube 65, so that the distance between the two adjacent cutting blades 22 is easy to accurately control.

[0092] The implementation principle of a photovoltaic welding strip slitting device in an embodiment of the present application is as follows: when in use, the adjustment cylinder 441 drives the two-way telescopic rod 442 to move away from the turntable 211, releases the fixation of the chain ring 43 on the cutting blade 22, and allows the cutting blade 22 to be adjusted equidistantly under the magnetic force of the electromagnet 41, and the damping cylinder 51 drives the sliding rod 53 to slide in the damping groove 541, and under the current limiting action of the damping capillary 52, the cutting blade 22 slides slowly, so that the distance between two adjacent cutting blades 22 is easy to control, and then the adjustment cylinder 441 drives the two-way telescopic rod 442 to approach the turntable 211, so that the clamping rod 42 is inserted into the chain hole of the chain ring 43 to fix the cutting blade 22 and the cutting shaft 21, and the motor 71 is started. The motor 71 drives the cutting blade 22 of the first cutting blade assembly 2 and the cutting blade 22 of the second cutting blade assembly 3 to rotate through the gear 72 and the two gear rings 73, so that photovoltaic welding strips of different widths can be cut.

[0093] When the distance between two adjacent cutting blades 22 needs to be adjusted, the switch valves 521 are closed one by one, so that each cutting blade 22 is fixed to the cutting shaft 21 individually, so that photovoltaic welding strips of different widths can be cut out at the same time.

[0094] When adjusting the distance between two adjacent cutting blades 22, the pull rope 63 and the display spring 64 cooperate to drive the display panel 62 to slide, and the display panel 62 drives the indicator plate 66 to slide through the colored liquid. The indicator plate 66 indicates on the scale 652 of the transparent display tube 65, so that the distance between two adjacent cutting blades 22 can be easily and accurately controlled.

[0095] 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.
