DETAILED DESCRIPTION

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] Example 1

[0032] like Figure 1-Figure 3As shown, a device for cutting and punching adhesive films or backsheets for photovoltaic modules comprises a workbench 10, a cutting frame 2, a punching frame 4, a cutting blade 14 located on the cutting frame 2, and a punch 6 located on the punching frame 4; the cutting frame 2 and the punching frame 4 are rod-shaped structures, and the workbench 10 is provided with a slide rail 7 for the reciprocating movement of the cutting frame 2 and the punching frame 4, which is used to adjust the cutting and punching positions in the length direction according to the model of the module, and one end of the cutting frame 2 and the punching frame 4 is movably installed in the slide rail 7, and the cutting frame 2 and the punching frame 4 can respectively drive the cutting blade 14 and the punch 6 to approach or move away from the surface of the workbench 10. When cutting or punching is required, the cutting frame 2 or the punching frame 4 is pressed against the surface of the workbench 10; the cutting blade 14 can reciprocate along the cutting frame 2, and a plurality of punches 6 are arranged on the punching frame 4.

[0033] The film or backing board is laid on the workbench 10, and the cutting blade 14 acts directly on the film or backing board to cut according to the size requirements. The puncher 6 acts directly on the film or backing board to punch holes on its surface. After the cutting frame 2 drives the cutting blade 14 to move along the slide rail 7, the cutting position can be adjusted to obtain a film or backing board of a specified length. After the punching frame 4 drives the puncher 6 to move along the slide rail 7, the hole position in the length direction of the film or backing board can be adjusted. One end of the cutting frame 2 is connected to the slide rail 7, and the other end can move up and down, so there is no need for an additional beam to lift the cutting frame 2. The installation and movement of the cutting frame 2 can be completed only by relying on the workbench 10. The installation of the punching frame 4 is the same.

[0034] In the present invention, the cutting frame 2 and the punching frame 4 only need to be located above the workbench 10 and can be extended in an arc shape or a straight line. In this embodiment, the cutting frame 2 and the punching frame 4 are both arranged perpendicular to the slide rail 7, that is, the slide rail 7 controls the position of cutting and punching in the length direction, the cutting frame 2 enables the cutting blade 14 to cut the film or backing plate along the width direction, and the punching frame 4 enables the punch 6 to adjust the punching position along the width direction.

[0035] The cutting frame 2 and the punching frame 4 are installed in the same manner with the workbench 10. This embodiment uses the cutting frame 2 as an example to specifically describe its connection structure with the workbench 10. The end of the cutting frame 2 is provided with a support that slides with the slide rail 7. The cutting frame 2 is hinged to the support. The support has a mounting portion 16 parallel to the outer side of the workbench 10. The clamping plate passes through the mounting portion 16 and is fixed to the outer side of the workbench 10. Figure 2 and Figure 4As shown, the support for mounting the cutting frame 2 is the cutting support 1, and the clamping disk that fixes the cutting support 1 is the cutting clamping disk 101. The cutting support 1 extends downward to form a mounting portion 16, which is threadedly engaged with the cutting clamping disk 101. When the cutting frame 2 is adjusted to the appropriate position, the cutting clamping disk 101 is screwed in and abuts against the workbench 10. At this time, the cutting support 1 can be fixed to the workbench 10. The mounting portion 16 can be parallel to the vertical side of the workbench 10. In this case, the cutting clamping disk 101 needs to be screwed in from the side. The protruding cutting clamping disk 101 will affect the movement of the staff. For this reason, in this embodiment, the mounting portion 16 is extended to the lower surface of the workbench 10, and the cutting clamping disk 101 can be screwed in from the bottom. Similarly, the support for mounting the punching frame 4 is the punching support 3.

[0036] Regarding the installation of the cutting blade 14 on the cutting frame 2, the cutting blade 14 needs to reciprocate along the cutting frame 2 to complete the cutting action. Therefore, the cutting blade 14 is connected to the cutting frame 2 in a sliding manner. The cutting blade 14 is a simple sheet structure and can be clamped by the structural design of the cutting frame 2. In order to ensure that the cutting blade 14 has sufficient extension length and to prevent the cutting blade 14 from falling, the present embodiment preferably installs the cutting blade 14 on the cutting fixture 13, and arranges a cutting guide rail 201 in the cutting frame 2 for the reciprocating movement of the cutting fixture 13. Figure 6 and Figure 9 As shown, the cutting frame 2 is hollow inside and penetrates from top to bottom. The cutting guide rail 201 is arranged in the cutting frame 2, serving as the movement track of the cutting fixture 13 and limiting the cutting fixture 13 in the upper and lower directions. The cutting fixture 13 has concave and convex parts that cooperate with the cutting guide rail 201. The cutting fixture 13 is a split structure. The cutting blade 14 is located at the bottom of the cutting fixture 13. A removable cutting clamp 1301 is provided at the bottom of the cutting fixture 13 for clamping the cutting blade 14.

[0037] Regarding the installation of the punch 6 on the punch frame 4, after the punching position is determined, the punch 6 is fixed on the punch frame 4, such as Figure 5 As shown, the punching frame 4 is also a vertically through structure, and a plurality of punches 6 are vertically installed in the punching frame 4.

[0038] In order to be able to adjust the hole position in the width direction according to actual needs, the punching frame 4 is provided with multiple slides 401 along the length direction, and the punch 6 adjusts its position within the range of the slides 401. Usually, a punch 6 is set in each slide 401, and the position of the punch 6 is limited within a specified area so that the hole positions are evenly arranged on the film or backboard. At this time, the punch 6 needs another component to be fixed, for example, the same fixing method as the cutting support 1 is adopted. In this embodiment, the punching frame 4 is provided with a retaining frame 5 sliding along the length direction, and the punch 6 is fixed in the retaining frame 5. The knob 501 passes through the slide 401 and is connected to the retaining frame 5 so that the knob 501, the retaining frame 5 and the punching frame 4 are relatively fixed. The retaining frame 5, as a contact component with the knob 501, can protect the punching frame 4. At the same time, the retaining frame 5 can also cooperate with the punching frame 4 to achieve vertical limit.

[0039] Example 2

[0040] In the first embodiment, the rotation of the cutting frame 2 and the punching frame 4 requires manual operation, which cannot guarantee the operation accuracy. In this embodiment, a hydraulic rod 15 is installed on each of the supports, and the extended end of the hydraulic rod 15 is connected to the cutting frame 2 or the punching frame 4. That is, the extended end of the hydraulic rod 15 on the cutting support 1 is connected to the cutting frame 2, and the extended end of the hydraulic rod 15 on the punching support 3 is connected to the punching frame 4. Figure 7 and Figure 10 As shown, the lifting and lowering of the cutting frame 2 or the punching frame 4 are controlled by the extension and retraction of the hydraulic rod 15 .

[0041] Example 3

[0042] On the basis of the above embodiment, a gap is left between the cutting guide rail 201 and the end of the cutting frame 2 away from the slide rail 7 to form a tool replacement port 202. The cutting frame 2 has a baffle 203 for preventing the cutting fixture 13 from entering the tool replacement port 202. Figure 6 and Figure 8 As shown, the leftmost end of the cutting frame 2 has a gap, which serves as a tool change port 202. The width of this gap is greater than the thickness of the cutting fixture 13. Once the cutting fixture 13 reaches the tool change port 202, it is no longer subject to upper and lower position limits and can be directly removed for replacement of the cutting blade 14. This eliminates the need to replace the entire cutting frame 2, reducing repair costs in the event of a damaged cutting blade 14. A barrier 203 is normally located directly above the cutting frame 2, preventing the cutting fixture 13 from entering the tool change port 202. When the cutting blade 14 needs to be replaced, the barrier 203 is rotated and removed.

[0043] Example 4

[0044] On the basis of the above embodiment, protective pads corresponding to the cutting frame 2 and the punching frame 4 are laid on the workbench 10, and a clearance groove 801 is set on the top of the protective pad. Figure 1and Figure 11 As shown, the protective pad under the cutting frame 2 is a cutting pad 8, and the protective pad under the punching frame 4 is a punching pad 9. The make way slot 801 makes way for cutting and punching operations to avoid the cutting pad 8 or the punching pad 9 from obstructing the cutting or punching work. The setting of the cutting pad 8 and the punching pad 9 can protect the workbench 10, the cutting blade 14 and the punch 6.

[0045] Example 5

[0046] Based on the above embodiment, the device further includes a film roll frame 12 and a film roll 11 mounted on the film roll frame 12. The film is wound on the film roll 11 and is located on one side of the workbench 10 along the length of the slide rail 7. The film can be directly pulled out from the film roll 11 and laid on the workbench 10.

[0047] Instructions for use: When cutting the film, tighten the cutting clamping disc 101, fix the cutting support 1, adjust the distance between the punching support 3 and the cutting support 1 along the slide rail 7, after adjusting the distance, tighten the clamping disc at the bottom of the punching support 3, fix the punching support 3, lay the film on the workbench 10, the cutting pad 8 and the punching pad 9, lower the cutting frame 2, make the bottom of the cutting frame 2 fit between the film and the cutting pad 8, move the cutting fixture 13 along the cutting frame 2, and the cutting fixture 13 drives the cutting blade 14 to complete the cutting of the film; for the film or backboard that needs to be punched, adjust the knob 501 to let the retaining frame 5 slide inside the slide groove 401, adjust the position of the puncher 6, after adjusting to the specified position, tighten the knob 501, lower the punching frame 4, and knock the puncher 6 to complete the punching of the film or backboard.

[0048] When the cutting blade 14 needs to be replaced, first rotate the blocking piece 203 to move the cutting fixture 13 to the tool replacement port 202, take out the cutting fixture 13 upward, remove the cutting clamp 1301, replace the new cutting blade 14, install the cutting clamp 1301, and then place it at the tool replacement port 202, move the cutting fixture 13, and rotate the blocking piece 203 again to complete the replacement of the cutting blade 14.
