Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically to a film and tape material cutting device. Background Technology

[0002] Photovoltaic cells are mainly divided into crystalline silicon (including monocrystalline and polycrystalline cells) and amorphous silicon. During the production of photovoltaic cells, a film coating process is required. Before coating, the film strip needs to be cut, and then the cut film strip is coated onto the cell.

[0003] When cutting the film strip, the film strip will deviate to a certain extent when the cutter cuts it, which will change the size of the cut film strip and affect the subsequent lamination process. Utility Model Content

[0004] To address the problems in the prior art, this application provides a film strip material cutting device that enables the film strip to be effectively fixed during cutting, thereby improving the cutting accuracy.

[0005] The technical solution is as follows: A film tape material cutting device includes a cutting mechanism and a second film pressing mechanism, wherein the second film pressing mechanism and the cutting mechanism are arranged sequentially along the film conveying direction; the cutting mechanism includes a cutter, and a first film pressing mechanism is arranged on one side of the cutter and the first film pressing mechanism, and a first lower pressure plate is arranged below the first film pressing mechanism; the first film pressing mechanism includes a first pressure plate, and a first cylinder is connected to the top of the first pressure plate; the second film pressing mechanism includes a second pressure plate, and a fifth cylinder is connected to the top of the second pressure plate.

[0006] Specifically, the cutting mechanism includes a cutting frame, on which a third cylinder is mounted and connected to the top of the cutter; the first cylinder and the first lower pressure plate are both mounted on the cutting frame.

[0007] Preferably, a first track is provided below the cutting frame, the cutting frame is connected to the first track by a slider, and the fourth cylinder drives the cutting frame to move along the first track.

[0008] Preferably, an extension plate is provided on the cutting frame on one side of the cutter.

[0009] Specifically, the second film pressing mechanism includes a film pressing frame, the fifth cylinder is disposed on the top of the film pressing frame, and a second lower pressing plate is disposed on the film pressing frame below the second pressing plate, and a limit groove is provided on the second lower pressing plate.

[0010] Preferably, a second track is vertically arranged on the cutting frame, and the cutter is slidably arranged on the second track.

[0011] Preferably, limit blocks are symmetrically arranged on the first lower pressure plate.

[0012] In summary, by using the first and second film-pressing mechanisms in conjunction, the film belt is pressed down and fixed at positions near and far from the cutting position, respectively. This multi-position fixation of the film belt effectively prevents deviation during cutting, improving cutting accuracy. Furthermore, the addition of limiting blocks and limiting grooves, working together, limits the film belt at different positions, preventing deviation during transport and ensuring precise cutting.

[0013] Furthermore, a second track is added, through which the cutter moves up and down, ensuring that the cutter can move vertically and preventing it from swaying left and right during the lifting process, which would prevent the membrane strip from being cut off in one go.

[0016] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0017] like Figure 1 As shown, it includes a second film pressing mechanism 2 and a cutting mechanism 1 arranged in sequence along the direction of film belt conveying, so that the film belt passes through the second film pressing mechanism 2 and the cutting mechanism 1 in sequence. When the film belt is cut, the second film pressing mechanism 2 presses down and fixes the film belt, and the cutting mechanism 1 cuts the film belt.

[0018] like Figure 2 As shown, the cutting mechanism 1 includes a cutting frame 101. A third cylinder 106 is mounted on the top of the cutting frame 101. The output end of the third cylinder 106 is connected to a cutter 105. The third cylinder 106 controls the cutter 105 to move up and down, thereby cutting the film strip. A first film pressing mechanism 102 is also mounted on the cutting frame 101. The first film pressing mechanism 102 is installed on the side of the cutter 105 near the second film pressing mechanism 2, that is, the first film pressing mechanism 102 is located between the cutter 105 and the second film pressing mechanism 2. The first film pressing mechanism 102 can press down and fix the film strip a second time. At the same time, a first lower pressure plate 104 is also mounted on the cutting frame 101 below the second film pressing mechanism 2, so that the film strip can be placed on the first lower pressure plate 104.

[0019] It should be noted that a lower cutter is also installed below the cutter 105. With the cooperation of the upper and lower cutters, the upper and lower sides of the membrane tape are cut simultaneously, which can quickly cut the membrane tape and avoid damage to the membrane tape due to ineffective cutting.

[0020] like Figure 4 As shown, the first pressing mechanism 102 includes a first cylinder 1022, which is installed on the top of the cutting frame 101. A first pressure plate 1021 is installed at the output end of the first cylinder 1022. The first cylinder 1022 controls the first pressure plate 1021 to move up and down, thereby achieving secondary pressing and fixing of the film strip.

[0021] like Figure 5 As shown, the second film pressing mechanism 2 includes a film pressing frame 202, on which a fifth cylinder 201 is installed. The output end of the fifth cylinder 201 is connected to a second pressure plate 205. The fifth cylinder 201 controls the second pressure plate 205 to move up and down, thereby pressing and fixing the film strip.

[0022] The film strip is conveyed in a designated direction, passing sequentially through the cutting mechanism 1 and the second pressing mechanism 2. After the robotic arm pulls the film strip to the designated length, the fifth cylinder 201 controls the second pressure plate 205 to descend, pressing and fixing the film strip. Then, the first cylinder 1022 controls the first pressure plate 1021 to descend, pressing and fixing the film strip a second time. Next, the third cylinder 106 controls the cutter 105 to descend and cut the film strip. After cutting, the fifth cylinder 201, the first cylinder 1022, and the third cylinder 106 control the corresponding parts to return to their initial positions. The second pressure plate 205's pressing and fixing determines the length of the film strip, ensuring it is fixed. The first pressure plate 1021's pressing and fixing again secures the film strip, preventing it from shifting during cutting. These two pressing and fixing processes prevent the film strip from shifting during cutting, improving the cutting accuracy.

[0023] like Figure 3 As shown, an extension plate 109 is installed on one side of the cutter 105 on the cutting frame 101, which can place the film strip on the extension plate 109.

[0024] like Figure 2 and Figure 3 As shown, a mounting base is provided below the cutting frame 101, and a symmetrical first track 108 is provided on the mounting base. The cutting frame 101 is connected to the first track 108 via a slider, allowing the cutting frame 101 to move along the first track 108. A fourth cylinder 107 is also mounted on the mounting base, and the output end of the fourth cylinder 107 is connected to the cutting frame 101, controlling the movement of the cutting frame 101. After the film strip is cut, a robotic arm moves the cut film strip to a designated position. When cutting the next film strip, the robotic arm needs to grasp one end of the film strip again. To facilitate the gripping of the robotic arm, after the robotic arm grasps the cut film strip, the fourth cylinder 107 controls the cutting frame 101 to move a short distance towards the second film pressing mechanism 2, so that one end of the film strip can be exposed outside the extension plate 109. This makes it easier for the robotic arm to grasp the film strip. When the robotic arm moves the film strip, the fourth cylinder 107 controls the cutting frame 101 to move back to the initial position.

[0025] like Figure 2 As shown, limit blocks 103 are symmetrically arranged on the first lower pressure plate 104. The distance between the limit blocks 103 is designed according to the width of the membrane belt. The limit blocks 103 can guide the membrane belt.

[0026] like Figure 3As shown, a second track 110 is vertically arranged on the cutting frame 101. The cutter 105 is connected to the second track 110 through a slider, so that the cutter 105 can move along the second track 110. By limiting the movement of the second track 110, the cutter 105 can be prevented from swaying left and right during the descent, thus improving the cutting accuracy.

[0027] like Figure 5 As shown, a second lower pressure plate 203 is disposed on the film pressing frame 202 below the second pressure plate 205. A limiting groove 204 is provided on the second lower pressure plate 203, and the width of the limiting groove 204 is set according to the width of the film strip. The film strip is placed in the limiting groove 204 for limiting and guiding.

[0028] In actual use, the membrane belt is conveyed along a designated direction, passing sequentially through the second lower pressure plate 203, the first lower pressure plate 104, and the extension plate 109, and is limited by the limiting groove 204 and the limiting block 103. The robotic arm grasps one end of the membrane belt and pulls it. When pulled to the designated length, the fifth cylinder 201 controls the second pressure plate 205 to descend, pressing down and fixing the membrane belt. Then, the first cylinder 1022 controls the first pressure plate 1021 to descend, pressing down and fixing the membrane belt a second time. Next, the third cylinder 106 controls the cutter 105 to descend and cut the membrane belt. After cutting, the robotic arm moves the cut membrane belt to a designated position, and the fifth cylinder 201, the first cylinder 1022, and the third cylinder 106 control the corresponding parts to return to their initial positions. The fourth cylinder 107 controls the cutting frame 101 to move a short distance towards the second film pressing mechanism 2, so that one end of the film strip can protrude outside the extension plate 109, facilitating the subsequent gripping of the film strip by the robotic arm. When the robotic arm grips and moves the film strip, the fourth cylinder 107 controls the cutting frame 101 to move back to the initial position. By repeating the above operation, the film strip can be continuously cut without shifting during the cutting process.
