Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic technology, and in particular to a material pressing and cutting mechanism. Background Art

[0002] Before the bus bar is welded to the battery string of the photovoltaic module, it needs to be cut to ensure its matching degree with the battery string. In the cutting mechanism in the prior art, when the cutting knife on it cuts the front end of the bus bar, due to the extrusion of the cutting knife, the rear end of the bus bar will tilt upward, which not only increases the cutting difficulty of the cutting knife, but also the tilted bus bar will cause the cutting position of the cutting knife to change, which greatly affects the cutting accuracy of the cutting knife.

Detailed implementation mode

[0032] The following further details this application in conjunction with the attached drawings.

[0033] See Figures 1 - 3 As shown, a pressing and cutting mechanism is shown, including a base 5. Along the length direction of the base 5, an unwinding component 4, a pressing component 1, and a cutting component 2 are sequentially arranged. Among them, the unwinding component 4, the pressing component 1, and the cutting component 2 are combined into a pressing and cutting unit. There are two such pressing and cutting units, which are respectively located on both sides of the width direction of the base 5. The two pressing and cutting units can cut two groups of busbars simultaneously, improving the cutting efficiency of the busbars.

[0034] In this embodiment, as shown in combination with Figures 2 - 3 The pressing component 1 includes a first material groove 11, a pressing block 12 that can be lifted and is arranged above the first material groove 11, and a first driving module 13 for driving the pressing block 12 to lift. The cutting component 2 includes a second material groove 21, a cutting knife 22 that can be lifted and is arranged above the second material groove 21, and a second driving module 23 for driving the cutting knife 22 to lift. The extending direction of the first material groove 11 coincides with the extending direction of the second material groove 21, and the extending directions of both are consistent with the arrangement direction of the unwinding component 4, the pressing component 1, and the cutting component 2.

[0035] During cutting, the unwinding component 4 unwinds the rolled busbars outwards. The busbars pass through the first material groove 11 and the second material groove 21 in sequence. The pressing block 12 descends and presses the rear end of the busbar. Subsequently, the cutting knife 22 descends and cuts off the front end of the busbar. In this way, the pressing block 12 can buckle on the rear end of the busbar, preventing the rear end of the busbar from warping upwards, reducing the cutting difficulty of the cutting knife 22, and improving the cutting accuracy of the cutting knife 22. At the same time, the first material groove 11 and the second material groove 21 can form a conveying channel for the busbar, enabling the busbar to be conveyed forward while being cut, greatly improving the overall processing efficiency of the busbar.

[0036] In this embodiment, as shown in Figure 2As shown, relief grooves are respectively formed in the middle parts of the two side walls of the first material tank 11, a material pressing cavity 14 is formed between the two relief grooves, and the material pressing block 12 is suspended above the material pressing cavity 14. The material pressing cavity 14 can accommodate the material pressing block 12 to prevent the first material tank 11 from interfering with the lifting of the material pressing block 12.

[0037] As Figure 3 shown, at one end of the second material tank 21 away from the first material tank 11, there is a cutting opening 211, and the cutting knife 22 is suspended outside the cutting opening 211 and abuts against the cutting opening 211. When the cutting knife 22 descends, the edge of the cutting opening 211 can cooperate with the cutting knife 22 to cut the bus bar, facilitating the cutting knife 22 to quickly cut off the bus bar.

[0038] In this embodiment, referring again to Figure 2 shown, the material pressing assembly 1 further includes a material pressing base 15, a first installation groove 16 formed in the material pressing base 15, and a first groove block 17. The notch of the first installation groove 16 is formed on the side of the material pressing base 15. The first groove block 17 is detachably carried on the lower side wall of the first installation groove 16. The first material tank 11 is formed in the upper part of the first groove block 17. The material pressing block 12 is vertically movably arranged on the upper side wall of the first installation groove 16. In this way, the detachable first groove block 17 can realize the modularization of the first material tank 11. When cutting bus bars of different specifications, different specifications of the first groove block 17 can be installed in the first installation groove 16, which greatly increases the application range of the material pressing assembly 1 and saves costs.

[0039] Among them, the first driving module 13 is a cylinder, which is arranged on the top of the material pressing base 15 and its piston rod extends and retracts along the vertical direction. The material pressing block 12 is coaxially connected to the lower end of the piston rod.

[0040] In this embodiment, referring again to Figure 3 shown, the cutting assembly 2 further includes a cutting base 24, a second installation groove 25 formed in the cutting base 24, and a second groove block 26. The second groove block 26 is detachably embedded in the second installation groove 25. The second material tank 21 is formed in the upper part of the second groove block 26. In this way, the detachable second groove block 26 can realize the modularization of the second material tank 21. When cutting bus bars of different specifications, different specifications of the second groove block 26 can be installed in the second installation groove 25, which greatly increases the application range of the cutting assembly 2 and saves costs.

[0041] The second driving module 23 includes a cylinder and a connecting rod. The cylinder is arranged at the top of the cutting seat 24 and its piston rod is extended and retracted along the length direction of the second material trough 21. The upper end of the connecting rod is hinged to the end of the piston rod, and the lower end is hinged to the lower part of the cutting seat 24. The cutter 22 is hinged to the connecting rod. During cutting, the piston rod of the cylinder can drive the connecting rod to rise and fall during its extension and retraction process, thereby driving the cutter 22 to rise and fall, so that the cutter 22 can cooperate with the cutting opening 211 to cut the busbar.

[0042] In this embodiment, the second material trough 21 has a feed port at one end close to the first material trough 11, and the diameter of the feed port gradually decreases in the direction away from the first material trough 11. The feed port with a gradually decreasing diameter not only facilitates the transfer of the busbar between the first material trough 11 and the second material trough 21, but also can correct the busbar in the vertical direction to improve its cutting accuracy.

[0043] Two rotatable guide wheels 27 are also provided in the second material trough 21, and the rotation axis of the guide wheels 27 extends in the vertical direction, and the arrangement direction of the two guide wheels 27 is perpendicular to the length direction of the second material trough 21. The two guide wheels 27 can horizontally correct the busbars entering the second material trough 21 to prevent the busbars from being offset during the conveying process and affecting the cutting accuracy.

[0044] In this embodiment, a limit block 28 is provided on the upper groove wall of the second material trough 21, and the length direction of the limit block 28 is the same as the length direction of the second material trough 21. The projection of the limit block 28 on the lower groove wall of the second material trough 21 is located between the two guide wheels 27. The limit block 28 can block above the bus bar to prevent the bus bar from tilting upward during the conveying and cutting process.

[0045] In this embodiment, again combined Figure 1 As shown, two guide rails are also arranged on the base 5 along its length direction, and the two cutting assemblies 2 are slidably arranged on the two guide rails along the direction close to or away from the pressing assembly 1, and the pressing and cutting mechanism also includes a third driving module 3 for driving the cutting assembly 2 to slide. The third driving module 3 includes a cylinder and a driving plate, and the piston rod of the cylinder is retracted along the length direction of the base 5. The driving plate is connected to the end of the piston rod, and its end away from the cylinder is respectively connected to the two cutting assemblies 2. The slidable cutting assembly 2 can adjust the distance between it and the pressing assembly 1, so as to adjust the cutting length of the busbar.

[0046] In this embodiment, the unwinding assembly 4 includes an unwinding wheel 41 rotatably arranged, an unwinding groove 42 provided around the circumference of the unwinding wheel 41, and a limiting wheel 43 rotatably arranged on the side of the unwinding wheel 41. The limiting wheel 43 is partially embedded in the unwinding groove 42. The rotation axes of the unwinding wheel 41 and the limiting wheel 43 are parallel to each other and extend along the width direction of the base 5. The limiting wheel 43 can resist against the side of the bus bar, effectively preventing the bus bar from loosening and falling off during the unwinding process.

[0047] A sensor 6 is also provided on the side of the unwinding wheel 41. The sensor 6 can detect the bus bar being unwound outward to timely replace the new unwinding wheel 41 after the bus bar is completely unwound.

[0048] The implementation principle of a material pressing and cutting mechanism according to an embodiment of the present application is as follows:

[0049] Unwind the bus bar from the unwinding wheel 41, then sequentially feed the unwound bus bar through the first material groove 11 and the second material groove 21, then the pressing block 12 descends and presses the rear end of the bus bar, and finally the cutting knife 22 descends to cut the bus bar.

[0050] The above are all the preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
