Description

Technical Field

[0001] The utility model relates to the technical field of tape / strip cutting equipment, in particular to a film cutting device and a film laying machine. Background Art

[0002] Existing photovoltaic modules require adhesive film to be laid around the perimeter and center of the module. For example, Chinese patent publication number CN117577712B describes an EVA edge laying machine based on visual correction technology. This machine performs both film cutting and laying on the short edges of photovoltaic modules.

[0003] However, the development of photovoltaic modules requires that the long sides of the modules also need to be covered with film. In this case, the film needs to be separated from the film roll and cut into appropriate lengths.

[0004] The use of the roller film roll in the above patent for loading and cutting is no longer suitable, because the long side of the photovoltaic module is much longer than the short side. Using a long roller film roll will take up a lot of equipment space, so now a very narrow film roll is used to pull out the required long side length before cutting.

[0005] Nowadays, the long-side film cutting in the component workshop is still done manually. Under the premise that the short-side automatic cutting and loading has been realized, the long-side automatic loading and cutting has also become an urgent need. The handling and hot-joining of the long-side film can refer to the handling and hot-joining structure of the short side, but there is no precedent for cutting the long-side film. Summary of the Invention

[0006] The purpose of the utility model is to provide a film cutting device and a film laying machine.

[0007] The utility model provides the following technical solutions:

[0008] One of the technical solutions is: a film cutting device, including a mounting plate, a blade and a telescopic power device that drives the blade to perform cutting action. The blade is installed on the mounting plate, the blade is movably installed at one end of the mounting plate, and the telescopic power device drives the other end of the mounting plate; a protective plate is also elastically and slidably installed on the mounting plate, and the protective plate is configured to block the blade.

[0009] The protective plate is sleeved on the mounting plate and is slidably connected to the mounting plate through a slide rail slider. The protective plate and the mounting plate are also connected through an elastic member, which pushes the protective plate to move away from the mounting plate.

[0010] The provision of the protective plate protects the blade during operation and prevents the blade from being broken or damaged by foreign objects.

[0011] A mounting groove is provided on the mounting plate relative to the elastic member, and a protrusion is formed on the protective plate relative to the mounting groove. The protrusion is arranged in the mounting groove, one end of the elastic member abuts one end of the mounting groove, and the other end of the elastic member abuts the protrusion.

[0012] By providing the elastic member, the protective plate can slide passively under the action of the elastic member, thereby saving the cost of the driving structure and achieving the function of active protection.

[0013] The mounting plate further comprises a blade pressing plate, which is arranged at a relative position between the fixed blade and the mounting plate.

[0014] The blade can be pressed by the clamping plate to avoid relative displacement of the blade during cutting, which affects the cutting accuracy.

[0015] The blade is rotatably mounted on a mounting plate. A rotating shaft is provided on the mounting plate at a position relative to the geometric center of the blade. A rotating hole is provided on the blade at a position relative to the rotating shaft.

[0016] The rotary connection of the blade facilitates the rotation of the blade relative to the mounting plate, and the rotary hole is provided at the geometric center to ensure that the relative position of the cutting edge is determined after each rotation.

[0017] The blade includes at least three cutting edges.

[0018] By setting at least three cutting edges, when the blade needs to be replaced, it only needs to rotate the corresponding cutting edge to achieve the continued use of the blade, which greatly reduces material consumption and shortens the blade changing process.

[0019] The guard plate is provided with an observation port relative to the blade, and the observation port is configured to check the condition of the blade.

[0020] By setting the observation port, the wear of the blade can be observed without stopping the equipment, so that the operator can know and adjust or replace the blade more conveniently.

[0021] A guide component is also provided in the installation groove, and the elastic component is sleeved on the guide component.

[0022] By setting the guide components, the phenomenon of the protective plate getting stuck during movement is further avoided, thus ensuring the stable operation of the equipment.

[0023] In summary, through the film cutting device provided in this application, automatic cutting of the film is realized, which saves labor costs. At the same time, the setting of the protective plate can protect the blade during operation to prevent the blade from being broken or damaged by foreign objects; not only that, through the setting of the observation port, the wear of the blade can be observed without stopping the equipment, so that the operator can more conveniently know and adjust or replace the blade.

[0024] Finally, the present application also provides a film laying machine, including a film loading device, a film conveying device and a film hot-dot device. The film loading device conveys the film to the film conveying device, and the film hot-dot device hot-dots the film onto the component. It also includes a film cutting device. The film cutting device is arranged in the process of the film loading device and the film conveying device. The film cutting device is configured to cut the film conveyed by the film loading device to the film conveying device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present application relates to a film cutting device and a film laying machine, which are explained in detail below through specific implementation methods.

[0035] A film cutting device further includes: a transverse movement portion, disposed above the film cutting device;

[0036] The film cutting device needs to change position to correspond to films at different locations. Therefore, the film cutting device also includes: a transverse motion portion, which is placed above the film cutting device; the transverse motion portion includes a transverse servo module 1 and a slide rail 3 mounted parallel to the transverse servo module 1, on which a slider 4 is slidably mounted. The transverse servo module 1 and the slide rail 3 are fixedly mounted on the back plate 10. The slider 4 is connected to the movable end of the transverse servo module 1 via a drive connecting plate 2, and the main body of the film cutting device is connected to the drive connecting plate 2. The provision of the transverse motion portion allows the main body of the cutting device to move laterally, allowing the main body of the film cutting device to cut films at different horizontal positions.

[0037] The main part of the film cutting device also includes: a mounting plate 15, a blade 8 and a telescopic power device that drives the blade 8 to perform a cutting action, and the telescopic power device drives the other end of the mounting plate 15; in this embodiment, the telescopic power device adopts a telescopic cylinder 11, the fixed end of the telescopic cylinder 11 is connected to the drive connecting plate 2, and the movable end of the telescopic cylinder 11 is connected to the mounting plate 15. The mounting plate 15 and the drive connecting plate 2 are slidably connected through the second slide rail 26 and the second slider 27. When the telescopic cylinder 11 starts to telescope, the movable end of the telescopic cylinder drives the mounting plate 15 to move up and down on the drive connecting plate 2, thereby driving the blade 8 to move up and down.

[0038] The mounting plate 15 includes a blade pressing plate 9, which is arranged at a position relative to the fixed blade 8 and the mounting plate 15. In this embodiment, the blade 8 is mounted between the blade pressing plate 9 and the mounting plate 15. The blade pressing plate 9 presses the blade 8 tightly against the mounting plate 15, thereby fixing the position of the blade 8.

[0039] After loosening the blade clamping plate 9, the blade 8 can be rotatably mounted on one end of the mounting plate 15. Specifically, a rotating shaft 61 is provided on the mounting plate 15 relative to the geometric center position of the blade 8, and a rotating hole 62 is opened on the blade 8 relative to the rotating shaft 61. The rotating hole 62 is clearance-matched with the rotating shaft 61, so that the blade 8 can rotate around the rotating shaft 61. In this embodiment, the blade 8 has five cutting edges 63. When used, two adjacent cutting edges 63 and the cutting angles 64 corresponding to these two cutting edges 63 are utilized. When the cutting angle 64 is damaged, by rotating the blade 8, the cutting action can be performed using another cutting angle 64, thereby avoiding frequent material replacement due to damage of the blade 8, reducing material consumption and speeding up the production rhythm.

[0040] A protective plate 20 is elastically and slidably mounted on the mounting plate 15 . The protective plate 20 is configured to shield the blade 8 . This arrangement not only prevents the risk of damage to the blade 8 but also prevents the operator from being injured during operation. In this embodiment, the protective plate 20 is sleeved on the mounting plate 15 and is slidably connected to the mounting plate 15 through the third slide rail 51 and the third slider 52. The protective plate 20 and the mounting plate 15 are also connected by an elastic member, and the elastic member pushes the protective plate 20 to move away from the mounting plate 15, wherein a mounting groove 31 is provided on the mounting plate 15 relative to the elastic member, and a protrusion 24 is formed on the position of the protective plate 20 relative to the mounting groove 31. The protrusion 24 is provided in the mounting groove 31, and one end of the elastic member abuts one end of the mounting groove 31, and the other end of the elastic member abuts the protrusion 24. In actual use, the elastic member uses a spring 23. The elastic member only needs to be able to push the protective plate 20 to move. The spring 23 is just an example. Shrapnel or other structures that can achieve this function should be within the protection scope of this application. A gap 65 is also provided at the bottom of the protective plate 20, and the blade 8 can perform a telescopic cutting action through the gap 65.

[0041] When adopting the driving structure of the above-mentioned protective plate 20, occasional jamming occurs during actual operation. Therefore, in this embodiment, a guide component is further provided in the installation groove 31. The guide component uses a guide column 22. The protrusion 24 is provided with a guide hole 25 relative to the guide column 22. The guide column 22 passes through the guide hole 25. The spring 23 is sleeved on the outside of the guide column 22. One end of the spring 23 abuts one end of the installation groove 31, and the other end abuts the protrusion 24, which further avoids the jamming phenomenon and ensures the stability of the equipment.

[0042] Under normal circumstances, the protective plate 20 is provided with an observation port 40 relative to the blade 8. In this embodiment, the observation port 40 is a plurality of through holes in a rectangular array. The wear of the blade 8 can be observed through the plurality of through holes without stopping the equipment, thereby making it easier for the operator to know and adjust or replace the blade 8.

[0043] The film cutting method, based on the above-mentioned film cutting device, includes the following steps:

[0044] Under normal conditions, the elastic member pushes the guard plate 20 to slide to the lowest position, and the guard plate 20 fully protects the blade 8;

[0045] Step 1: The telescopic power device drives the mounting plate 15 to move downward, and the bottom of the protective plate 20 abuts against the material platform and presses the material;

[0046] Step 2: The telescopic power device continues to drive the mounting plate 15 downward. At this time, the protective plate 20 cannot move downward due to the contact with the material platform. The protective plate 20 pushes the elastic member to contract, and the protective plate 20 moves upward relative to the blade 8. The blade 8 extends out from the bottom edge of the protective plate 20 and cuts the material.

[0047] Step 3: After the target cutting is completed, the telescopic power device retracts, driving the mounting plate 15 to move upward. The protective plate 20, under the action of the elastic member, still maintains the state of pressing the material. The protective plate 20 moves downward relative to the blade 8 until the blade 8 retracts into the protective plate 20;

[0048] Step 4: The telescopic power device continues to retract, and after the elastic member pushes the protective plate 20 to the lowest position, the protective plate 20 moves upward under the drive of the mounting plate 15, and the bottom of the protective plate 20 no longer abuts the material;

[0049] Step 5: The telescopic power device retracts to the upper limit position, and the film cutting device returns to normal state, waiting for the next cutting step.

[0050] The film laying machine is based on the above-mentioned film cutting device, which also includes a film feeding device, a film conveying device and a film hot-stamping device. The film feeding device conveys the film to the film conveying device, and the film hot-stamping device hot-stamps the film onto the component. The film cutting device is arranged in the process of the film feeding device and the film conveying device, and the film cutting device is configured to cut the film conveyed by the film feeding device to the film conveying device.
