Description

Technical Field

[0001] This utility model relates to the field of slitting equipment technology, specifically to a component EVA encapsulation film correction and slitting machine. Background Technology

[0002] In the photovoltaic (PV) module manufacturing industry, EVA encapsulating film is a key encapsulation material, and its slitting quality directly affects the performance and reliability of PV modules. During module production, EVA encapsulating film needs to be precisely slitted to meet the encapsulation requirements of PV modules of different specifications. The correction step in the slitting process is crucial. Precise correction ensures neat cuts in the film, avoiding problems such as poor encapsulation and internal short circuits in the module caused by cut deviations. This, in turn, guarantees the photoelectric conversion efficiency and long-term stability of the PV module, improving the product's market competitiveness.

[0003] The shortcomings of existing technology:

[0004] Currently, the existing method for correcting the tilt of EVA encapsulation film during slitting is typically achieved by adjusting the overall position of the film on the conveyor rollers. Specifically, when tilting is detected during transport, the film's position on the conveyor rollers is adjusted manually or mechanically to restore it to a parallel position with the transport direction before slitting. However, this correction method has significant drawbacks. Because EVA encapsulation film is relatively long, it is prone to tilting and shifting to varying degrees during transport. Overall correction requires considerable time and effort, resulting in extremely low slitting efficiency and severely impacting production line rhythm and capacity. Furthermore, some production lines choose to perform localized correction at the cutting points to improve efficiency, aligning them perpendicular to the cutting path. However, this localized correction method causes significant local distortion of the film, making it susceptible to deformation or even breakage due to uneven stress, leading to film damage, reduced film utilization, and lower product quality.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified. Example

[0034] Please see Figure 1-7 As shown, the present invention provides a technical solution for an EVA encapsulation film correction and slitting machine for components: an EVA encapsulation film correction and slitting machine for components includes two mounting plates 1, a conveying roller 2 for conveying the film is installed between the two mounting plates 1, a correction mechanism 3 for adjusting the cutting path is installed at the upper end of the two mounting plates 1, a cutting component 4 is installed at the upper end of the correction mechanism 3, the cutting component 4 can be a circular knife, a laser cutting machine or an ultrasonic cutting machine, a calibration component 5 is installed between the two mounting plates 1 on the feeding side of the cutting component 4, and a controller 6 is also installed on the inner side of the two mounting plates 1;

[0035] The correction mechanism 3 includes a horizontal support frame 301, an adjusting frame 303, and an adjusting slide bar 305. The horizontal support frame 301 is movably mounted on the upper end of the two mounting plates 1 and is telescopic. During the left and right rotation correction process of the horizontal support frame 301, the telescopic capacity of its end ensures that no motion interference occurs. One end of the horizontal support frame 301 is movably connected to one side of the mounting plate 1 through a horizontal slide groove, and the other end of the horizontal support frame 301 is rotatably connected to the other side of the mounting plate 1. That is, the horizontal support frame 301 can rotate around one end as an axis, and the other end slides in the horizontal slide groove on the mounting plate 1 to achieve angle adjustment. An electric slide rail 302 for driving the horizontal movement of the cutting piece 4 is installed on one side of the upper surface of the horizontal support frame 301. The adjusting frame 303 is movably mounted on the upper end of the calibration assembly 5, and a telescopic and mutually perpendicular positioning sleeve 304 is installed at the end of the adjusting frame 303. An adjusting slide bar 305 is located on one side of the upper surface of the horizontal support frame 301. A positioning sleeve 304 is fitted onto the adjusting slide bar 305 and slidably connected to it. When the adjusting frame 303 shifts, the telescopic nature of the positioning sleeve 304 ensures that it can slide on the adjusting slide bar 305 while maintaining its connection with the adjusting frame 303, preventing motion interference. Since the positioning sleeve 304 is fitted onto the adjusting slide bar 305, and the adjusting slide bar 305 is located on the horizontal support frame 301, the positioning sleeve 304 and the horizontal support frame 301 are perpendicular to each other.

[0036] When the slitting machine is working, the film is first conveyed to the designated position by the conveyor roller 2. Then, the calibration component 5 is activated, which drives the adjusting frame 303 to move and adjust the correction angle until the adjusting frame 303 is close to and parallel to the edge of the film. During the movement of the adjusting frame 303, the positioning sleeve 304 slides synchronously on the adjusting slide bar 305. If the film tilts on the conveyor roller 2, the adjusting frame 303 will also be tilted after it is in place. Since the positioning sleeve 304 is always perpendicular to the adjusting frame 303, the positioning sleeve 304 will apply a torsional force to the adjusting slide bar 305 during the movement of the adjusting frame 303. This torsional force will then drive the horizontal support frame 301 to rotate about one end as an axis, maintaining its relative perpendicularity to the adjusting frame 303. After the adjusting frame 303 is adjusted, the electric slide rail 302 on the horizontal support frame 301 is perpendicular to the film. At this time, the cutting piece 4 can accurately cut the film along the electric slide rail 302, and the cut is completely flush.

[0037] By actively adjusting the movement direction of the cutting part 4 through the correction mechanism 3, the cutting path is made perpendicular to the inclined film, achieving a precise and flat cutting effect. Compared with the traditional overall film adjustment, it is simple to operate, significantly improves cutting efficiency and correction efficiency, and the cutting part of the film will not be twisted, thus avoiding damage to the film and improving product quality.

[0038] The calibration assembly 5 includes two lead screws 501, a distance sensor 504, and a power box 505. The two lead screws 501 are rotatably connected between two mounting plates 1 on the feed side of the cutting piece 4. Mounting posts 502 are fixedly mounted on the nuts of both lead screws 501. A positioning shaft 503 is fixedly mounted on the upper end of each mounting post 502. One end of an adjusting frame 303 is rotatably connected to one positioning shaft 503. The adjusting frame 303 is also movably connected to the other positioning shaft 503 via a through slot, allowing the positioning shaft 503 to rotate or slide relative to the through slot. The distance sensor 504 is installed in a groove on the side wall of the two mounting posts 502, facing the adhesive film. The distance sensor 504 is used to detect the distance to the edge of the adhesive film. The power box 505 is installed on one side of the two mounting plates 1 to drive the two lead screws 501 to rotate. The power box 505 can independently control the two lead screws 501 through the engagement of a motor or clutch.

[0039] Once the adhesive film is in place before slitting, the power unit 505 controls the two lead screws 501 to rotate synchronously. The mounting column 502 then drives the adjusting frame 303 to move horizontally along the two lead screws 501 via the positioning shaft 503. The controller 6 continuously monitors the distance to the edge of the adhesive film using distance sensors 504. When one distance sensor 504 detects that the distance to the edge of the adhesive film has reached a set value, the controller 6 immediately stops the lead screw 501 located at that distance sensor. The other lead screw 501 continues to rotate until the distance sensor 504 above it also detects that the distance to the edge of the adhesive film has reached the set value. At this point, the adjusting frame 303 is parallel to the edge of the adhesive film, and the correction operation of the correction mechanism 3 is completed.

[0040] The calibration component 5 enables rapid capture of the tilt state of the adhesive film and quickly adjusts the adjustment frame 303 to be parallel to the tilted adhesive film, thereby cooperating with the correction mechanism 3 to quickly correct the cutting path and further improve the correction efficiency and cutting efficiency.

[0041] The lower end of the horizontal support frame 301 is connected to a positioning strip 7 via a telescopic rod. During the cutting process, the positioning strip 7 actively clamps and positions the area near the cut of the adhesive film, significantly improving the stability and cutting quality during the adhesive film slitting process.

[0042] Several balls 8 are movably installed between the inner walls of the two sides of the positioning sleeve 304 and the adjusting slide 305 to reduce friction, which significantly improves the smoothness of the positioning sleeve 304 moving on the adjusting slide 305.

[0043] A limiting rod 5011 is installed between the two mounting plates 1, below the two lead screws 501. The nuts on the two lead screws 501 are slidably connected to the limiting rod 5011 through through holes. The limiting rod 5011 can effectively prevent the nuts from rotating with the two lead screws 501.

[0044] The controller 6 is electrically connected to the electric slide rail 302, the distance sensor 504 and the power box 505 via wires. The controller 6 controls the operation of the power box 505 by receiving the distance signal from the distance sensor 504, thereby controlling the rotation of the two lead screws 501.

[0045] The working principle of this utility model is as follows:

[0046] In this embodiment, the EVA encapsulation film correction and slitting machine for components is used such that the film is first conveyed to a designated position by the conveyor roller 2. Then, the power unit 505 controls the two lead screws 501 to rotate synchronously. The mounting column 502 then drives the adjusting frame 303 to move horizontally along the two lead screws 501 via the positioning shaft 503. When both distance sensors 504 detect that the distance to the edge of the film reaches a set value, the adjusting frame 303 is parallel to the edge of the film. During the movement of the adjusting frame 303, the positioning sleeve 304 slides synchronously on the adjusting slide bar 305. If the film tilts on the conveyor roller 2, the adjusting frame 303 will also be tilted after positioning, and the horizontal support frame 301 will rotate about one end as an axis to maintain its relative perpendicularity to the adjusting frame 303. After the adjusting frame 303 is adjusted, the electric slide rail 302 on the horizontal support frame 301 reaches a perpendicular state to the film. At this time, the cutting piece 4 can precisely cut the film along the electric slide rail 302, resulting in a perfectly flush cut.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
