Description

Technical Field

[0001] This utility model relates to the field of circuit board production equipment, and in particular to a cutting device and a film application machine. Background Technology

[0002] In modern manufacturing, flexible printed circuit boards (FPCs) are important electronic components, with corresponding circuits mounted on their flexible insulating substrates. To protect these circuits, a protective film, known as a cover film, is typically applied to their surface using a laminating machine.

[0003] The cover film is typically adhered to the base paper to form a film stock, which is then wound into a roll. During production, the roll is unwound using an unwinding device, and then cut by a film cutting machine to obtain the required length of cover film (defined as a film unit). Subsequently, a laminating device removes the film unit from the base paper and applies it to the FPC. Additionally, a rewinding device is needed to rewind the base paper during production.

[0004] However, existing film cutting machines have difficulty controlling the cutting depth when cutting the cover film, which makes it easy for the film cutting machine to cut the cover film and the backing paper together, which is not conducive to the unwinding of the film material and the subsequent use of the film unit.

[0035] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] like Figure 1 and Figure 2As shown, in one embodiment, the cutting device 4 is used to cut the cover film of the film material, wherein the cover film covers the backing paper of the film material. The cutting device 4 includes a cutter support frame 41, a first cutter drive assembly 42, a cutter connecting assembly 43, a cutting blade 44, and a cutting depth limiting member 45; the cutter support frame 41 is connected to a support platform; the first cutter drive assembly 42 is connected to the cutter support frame 41 and to the cutter connecting assembly 43; the cutting blade 44 and the cutting depth limiting member 45 are both connected to the cutter connecting assembly 43; in the height direction of the cutting blade 44, the cutting blade 44 has a blade back 441 and a blade edge 442 arranged opposite to each other; the first cutter drive assembly 42... Component 42 drives the cutter connecting component 43 to move along the direction from the back of the blade 441 to the cutting edge 442, thereby bringing the cutting blade 44 closer to the support table to cut the cover film of the film material placed on the support table. When the cutter connecting component 43 moves along the direction from the back of the blade 441 to the cutting edge 442, the cutting depth limiting component 45 can abut against the support table. This limits the maximum distance the cutting blade 44 can move closer to the support table, ensuring that the cutting depth of the cutting device 4 is greater than or equal to the thickness of the cover film, and less than the sum of the thickness of the cover film and the thickness of the backing paper. By setting the cutting depth limiting component 45, the maximum cutting depth can be limited. During operation, it is only necessary to drive the cutting blade 44 closer to the support table until the cutting depth limiting component 45 abuts against the support table to ensure that the cutting depth of the cutting device 4 meets the requirements, thus facilitating the control of the cutting depth. The cutting depth of the cutting device 4 can refer to the depth to which the cutting blade 44 cuts into the film material in the direction from the back of the blade 441 to the cutting edge 442.

[0039] exist Figure 1 and Figure 2 In the directions shown, the height direction of the cutting blade 44 is parallel to the Z-axis direction.

[0040] In this embodiment, the support platform is used to support the cutting device 4, which can be placed on the ground.

[0041] When the first cutter drive assembly 42 drives the cutter connecting assembly 43 closer to the carrier table, the cutting blade 44 also approaches the carrier table and eventually comes into contact with the film material placed on the carrier table, thereby cutting the film material. When the cutter connecting assembly 43 continues to approach the carrier table, it will eventually drive the cutting depth limiting member 45 to contact the material placement device, thus preventing the cutter connecting assembly 43 from continuing to approach the carrier table and preventing the cutting blade 44 from cutting the backing paper. At this time, the cutting depth of the cutting blade 44 reaches its maximum value, and the maximum cutting depth of the cutting blade 44 is greater than or equal to the thickness of the cover film, but less than the sum of the thickness of the cover film and the thickness of the backing paper.

[0042] When the film material is placed on the support platform, the cover film of the film material is located on the side of the back paper away from the material placement device. In this way, when the cutting depth of the cutter 44 reaches its maximum value, it can cut the cover film but not the back paper.

[0043] like Figure 3 As shown, in one embodiment, the cutter connection assembly 43 includes a cutter connection seat 431 and a cutter holder 432; the cutter connection seat 431 is connected to the first cutter drive assembly 42; the cutter holder 432 is detachably connected to the cutter connection seat 431; and the cutting blade 44 is connected to the cutter holder 432.

[0044] In practical applications, different cutting blades 44 can be installed on different blade holders 432. For different cutting requirements (such as different cutting depths), the blade holder 432 and the cutting blades 44 connected to the blade holder 432 can be directly replaced, thereby improving work efficiency.

[0045] Moreover, if the tool holder 432 is damaged, only the tool holder 432 needs to be replaced, which can reduce maintenance costs.

[0046] like Figure 3 As shown, in one embodiment, the cutter connector 431 includes a cutter holder connecting plate 4311, a cutter holder clamping member 4312, and a cutter holder connector; the cutter holder connector includes a cutter holder connecting portion 4313 and a cutter holder pressing portion 4314; the cutter holder connector connects the cutter holder connecting portion 4313 and the cutter holder connecting plate 4311, and enables the cutter holder connecting portion 4313 and the cutter holder connecting plate 4311 to be in a locked state and a released state; when the cutter holder connecting portion 4313 and the cutter holder connecting plate 4311 are in the locked state, the cutter holder pressing portion 4314 can press the cutter holder 432 against the cutter holder connecting plate 4311; when the cutter holder connecting portion 4313 and the cutter holder connecting plate 4311 are in the released state, the cutter holder 432 can be detached from the cutter connector 431. This arrangement makes it more convenient to disassemble and install the cutter holder 432.

[0047] When the cutter holder connecting part 4313 and the cutter holder connecting plate 4311 are in the locked state, the cutter holder 431 may not be able to move relative to the cutter connecting seat 431. When the cutter holder connecting part 4313 and the cutter holder connecting plate 4311 are in the loosened state, the cutter holder 431 can move relative to the cutter connecting seat 431.

[0048] In one embodiment, the tool holder connecting part 4313 is provided with a through hole (defined as the first through hole), the tool holder connecting plate 4311 is provided with a threaded hole (defined as the first threaded hole), and the tool holder connector is a bolt. The tool holder connector passes through the tool holder connecting part 4313 from the first through hole and is threadedly engaged with the first threaded hole on the tool holder connecting plate 4311. By adjusting the depth of the tool holder connector screwed into the first threaded hole, the tool holder connecting part 4313 and the tool holder connecting plate 4311 can be in a locked state and a loosened state.

[0049] In one embodiment, both the tool holder connecting part 4313 and the tool holder pressing part 4314 are block structures, and the tool holder connecting part 4313 and the tool holder pressing part 4314 are connected to form an L-shaped structure.

[0050] In one embodiment, the blade holder connecting plate 4311 may be a flat plate, the surface of which is used to connect the blade holder clamping member 4312 and the surface of which is used to connect the first cutting blade drive assembly 42 are both planar.

[0051] Of course, in other embodiments, the detachable connection between the tool holder 432 and the cutter connecting seat 431 can also be achieved in other ways. For example, the tool holder 432 connecting seat may include the aforementioned tool holder connecting plate 4311 and cutter connecting member, but does not include the tool holder clamping member 4312. In this case, the tool holder 432 is provided with a first through hole, and the cutter connecting member passes through the through hole and is threaded into the first threaded hole on the tool holder connecting plate 4311. This allows the tool holder 432 to be detachably connected to the tool holder connecting plate 4311 through the cutter connecting member, thereby achieving a detachable connection between the tool holder 432 and the cutter connecting seat 431.

[0052] In one embodiment, the blade 442 is located below the blade back 441. In this case, the height direction of the cutting blade 44 can be parallel to the vertical direction, and the first cutting blade drive assembly 42 can drive the cutting blade connecting assembly 43 to move up and down. When the first cutting blade drive assembly 42 drives the cutting blade connecting assembly 43 to move downward, the cutting blade connecting assembly 43 approaches the support platform.

[0053] That is, the support platform is located below the cutting blade 44 and the cutting blade connecting assembly 43.

[0054] In another embodiment, the first cutter drive assembly 42 is connected to the upper surface of the cutter holder connecting plate 4311; the cutter holder 432 and the cutter holder clamping member 4312 are connected to the lower surface of the cutter holder connecting plate 4311. This facilitates the assembly of the cutter connecting assembly 43 and the cutting device 4.

[0055] In one embodiment, the cutting blade 44 is detachably connected to the blade holder 432, so that if one of them is damaged, only the damaged one needs to be replaced, thereby reducing the cost of using the cutting device 4.

[0056] like Figure 3 As shown, in one embodiment, the blade holder 432 includes a blade base plate 4321, a first blade pressure plate 4322, and a second blade pressure plate 4323; the blade base plate 4321 is used to connect to the blade connecting seat 431; the first blade pressure plate 4322 and the second blade pressure plate 4323 are spaced apart on the blade base plate 4321 along the thickness direction of the cutting blade 44, and clamp the cutting blade 44. Figure 3 In the direction shown, the thickness direction of the cutting blade 44 is parallel to the X-axis.

[0057] The thickness direction of the cutting blade 44 can be parallel to the front-to-back direction. When the cutting device 4 is used in a laminating machine, it is used in conjunction with the film winding device and the film unwinding device of the laminating machine. The film winding device and the film unwinding device can be spaced apart along the front-to-back direction, and the cutting device 4 is located between the film winding device and the film unwinding device. That is, the arrangement direction of the film winding device and the film unwinding device is parallel to the thickness direction of the cutting blade 44.

[0058] In addition, in the thickness direction of the cutting blade 44, the first cutting blade pressure plate 4322 and the second cutting blade pressure plate 4323 are both located on the same side of the cutting blade base plate 4321.

[0059] After assembly, the back of the cutting blade 441 can also abut against the cutting blade base plate 4321, which can prevent the cutting blade 44 from moving toward the cutting blade base plate 4321 when cutting the film material.

[0060] Furthermore, it should be understood that the back of the cutting blade 441 abuts against the cutting blade base plate 4321. In the height direction of the cutting blade 44, the height of the cutting blade 44 is greater than the height of the first cutting blade pressure plate 4322, and also greater than the height of the second cutting blade pressure plate 4323. Thus, the cutting edge 442 of the cutting blade 44 is located outside the space between the first and second cutting blade pressure plates 4322 and 4323. During operation, the cutting edge 442 of the cutting blade 44 can cut the covering film.

[0061] In addition, the cutting blade 44 is fixed on the blade holder 432 by clamping, which facilitates the assembly of the cutting blade 44 and the blade holder 432.

[0062] In one embodiment, the connection position of the second cutting plate 4323 on the cutting base plate 4321 is adjustable in the arrangement direction of the first cutting plate 4322 and the second cutting plate 4323. This allows the installation position of the second cutting plate 4323 on the cutting base plate 4321 to be adjusted according to the actual thickness of the cutting blade 44, so that the blade holder 432 can be adapted to cutting blades 44 of different thicknesses.

[0063] In one embodiment, the second cutter pressure plate 4323 is bolted to the cutter base plate 4321. The second cutter pressure plate 4323 has a through hole (defined as the second through hole), and the cutter base plate 4321 has a threaded hole (defined as the second threaded hole). The bolt passes through the second through hole into the second cutter pressure plate 4323 and engages with the corresponding second threaded hole on the cutter base plate 4321, thereby locking the second cutter pressure plate 4323 onto the cutter base plate 4321.

[0064] In addition, the diameter of the second through hole on the second cutter pressure plate 4323 can be larger than the diameter of the bolt passing through the second through hole. After assembly, there is a certain distance between the hole wall of the second through hole and the bolt inserted therein, so that when the bolt is loosened from the second cutter pressure plate 4323 and the cutter base plate 4321, the second cutter pressure plate 4323 can move radially along the second through hole, so as to realize the movement of the first cutter pressure plate 4322 and the second cutter pressure plate 4323 relative to the cutter base plate 4321 in the arrangement direction. Then, the second cutter pressure plate 4323 and the cutter base plate 4321 are locked with bolts to complete the adjustment of the connection position of the second cutter pressure plate 4323 on the cutter base plate 4321. In addition, the second through hole on the second cutter pressure plate 4323 can also be a waist-shaped hole, and extend along the arrangement direction of the first cutter pressure plate 4322 and the second cutter pressure plate 4323. The bolt passing through the second through hole can move relative to the second cutter pressure plate 4323 along the length direction of the second through hole.

[0065] like Figure 3 and Figure 4 As shown, in one embodiment, the blade holder 432 further includes a first cutting blade clamping member 4234 and a second cutting blade clamping member 4235; the first cutting blade clamping member 4234 is connected to the cutting blade base plate 4321 and is located on the side of the second cutting blade pressure plate opposite to the first cutting blade pressure plate; the second cutting blade clamping member 4235 is connected to the first cutting blade clamping member 4234 and abuts against the side of the second cutting blade pressure plate 4323 opposite to the first cutting blade pressure plate 4322; one of the first cutting blade clamping member 4234 and the second cutting blade clamping member 4235 is provided with a threaded hole, and the other is provided with a stud, and the threaded hole and the stud are threadedly engaged; when adjusting the depth of the stud screwed into the threaded hole, in the arrangement direction of the first cutting blade pressure plate 4322 and the second cutting blade pressure plate 4323, the second cutting blade clamping member 4235 can move closer to or further away from the first cutting blade pressure plate 4322.

[0066] When the second cutter clamping member 4235 approaches the first cutter pressure plate 4322, it can squeeze and push the second cutter pressure plate 4323 closer to the first cutter pressure plate 4322. This allows the second cutter pressure plate 4323 to press the cutting blade 44 onto the first cutter pressure plate 4322, making the cutting blade 44 more securely installed between the first cutter pressure plate 4322 and the second cutter pressure plate 4323.

[0067] In one embodiment, a threaded hole extends through the first cutter clamping member 4234 along the thickness direction of the cutter 44. A second cutter clamping member 4235 is screwed into the threaded hole of the first cutter clamping member 4234 from the side of the first cutter clamping member 4234 away from the second cutter pressure plate 4323, and extends out of the threaded hole of the first cutter clamping member 4234 from the side of the first cutter clamping member 4234 close to the second cutter pressure plate 4323, thereby abutting against the second cutter pressure plate 4323.

[0068] Furthermore, force can be applied to the second cutter clamping member 4235 from the side of the first cutter clamping member 4234 that is away from the second cutter pressure plate 4323, so that it can be brought closer to or away from the first cutter pressure plate 4322, which makes it convenient to apply force to the second cutter clamping member 4235.

[0069] In one embodiment, the second cutter clamping member 4235 is a bolt.

[0070] In one embodiment, the first cutter clamping member 4234 has multiple threaded holes, which are spaced apart along the length of the cutter 44. There are multiple second cutter clamping members 4235, and the threaded holes on the second cutter clamping members 4235 correspond one-to-one with those on the first cutter clamping members 4234. After assembly, the second cutter clamping members 4235 engage with their corresponding threaded holes, and each second cutter clamping member 4235 can abut against the side of the second cutter pressure plate 4323 opposite to the first cutter pressure plate 4322. This allows the cutter 44 to be more securely mounted on the cutter holder 432. Figures 1 to 3 In the directions shown, the length direction of the cutting blade 44 is parallel to the Y-axis, while the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0071] like Figure 3 As shown, in one embodiment, the cutter connecting seat 431 includes at least two cutter holder connectors and at least two cutter holder clamping members 4312. Each cutter holder clamping member 4312 corresponds to at least one cutter holder connector, and the cutter holder clamping member 4312 is connected to the cutter holder connecting plate 4311 through its corresponding cutter holder connector. In the length direction of the cutting blade 44, each cutter holder clamping member 4312 is respectively disposed on both sides of the cutter base plate 4321.

[0072] After assembly, the blade holder clamping component 4312 can press the cutter base plate 4321 onto the blade holder connecting plate 4311, thereby pressing the blade holder 432 onto the blade holder connecting plate 4311. Since both ends of the cutter base plate 4321 are pressed onto the blade holder connecting plate 4311 by the corresponding blade holder clamping component 4312, the blade holder 432 can be more firmly connected to the cutter connecting seat 431.

[0073] In one embodiment, the cutting depth limiting member 45 is detachably connected to the cutter base plate 4321. This allows for replacement of only the cutting depth limiting member 45 when it wears out, reducing maintenance costs. Furthermore, different cutting depths typically correspond to different cutting depth limiting members 45. Therefore, when the cutter holder 432 is replaced to accommodate different cutting depths, the cutting depth limiting member 45 connected to the cutter holder 432 can be replaced simultaneously, facilitating maintenance.

[0074] like Figure 3 As shown, in one embodiment, the cutting device 4 includes at least two cutting depth limiting members 45, which are respectively disposed on both sides of the cutting blade 44 along its length. This improves the limiting effect of the cutting depth limiting members 45 and prevents the cutting blade 44 from cutting the back paper of the film material.

[0075] Meanwhile, by placing the cutting depth limiting member 45 at both ends of the length direction of the cutting blade 44, interference with the operation of adjusting the second cutting blade clamping member 4235 can be avoided.

[0076] like Figure 1 and Figure 2 As shown, in one embodiment, the first cutter drive assembly 42 includes a cutter drive member 421, a cutter fixing block 422, and a cutter floating block 423; the cutter drive member 421 is connected to the cutter support frame 41 and connected to the cutter floating block 423; the cutter fixing block 422 is connected to the cutter connecting assembly 43 and together with the cutter connecting assembly 43, forms a floating space 424; the cutter floating block 423 is located within the floating space 424 and can move along the height direction of the cutting blade 44 within the floating space. 424 Internal movement; When the cutter drive member 421 drives the cutter floating block 423 to move along the direction from the back of the blade 441 to the blade edge 442, the cutter floating block 423 can press the cutter connector, so that the cutter 44 can cut the covering film of the film material placed on the support platform; When the cutter drive member 421 drives the cutter floating block 423 to move along the direction from the blade edge 442 to the back of the blade 441, the cutter floating block 423 can abut against the cutter fixing block 422, so as to drive the cutter connecting assembly 43 away from the support platform.

[0077] Because the blade floating block 423 can move within the floating space 424 along the height direction of the cutting blade 44, the blade connecting assembly 43 can move a certain distance relative to the cutting blade drive member 421 in the height direction of the cutting blade. Specifically, when the cutting blade connecting assembly 43 moves closer to the cutting blade drive member 421, the blade floating block 423 can abut against the blade connecting assembly 43 to prevent it from moving further closer to the cutting blade drive member 421; when the cutting blade connecting assembly 43 moves away from the cutting blade drive member 421, the blade floating block 423 can abut against the cutting blade fixing block 422 to prevent it from moving further away from the cutting blade drive member 421. The floating space 424 can absorb the adverse effects of errors generated during part size processing and assembly on control accuracy, thereby improving the control accuracy of the cutting blade 44's movement.

[0078] In one embodiment, the cutter fixing block 422 includes a first cutter fixing plate, a second cutter fixing plate, and a third cutter fixing plate. The first and second cutter fixing plates are both disposed on the third cutter fixing plate and spaced apart. Both the first and second cutter fixing plates are located on the side of the third cutter fixing plate closest to the cutter connecting assembly 43. In this case, the cutter fixing block 422 is generally U-shaped. The end of the first cutter fixing plate facing away from the third cutter fixing plate is connected to the cutter connecting assembly 43, and the ends of both the first, second, and third cutter fixing plates facing away from the third cutter fixing plate are also connected to the cutter connecting assembly 43. The first, second, and third cutter fixing plates, together with the cutter connecting assembly 43, form a floating space 424.

[0079] Additionally, the third cutter fixing plate is provided with a clearance hole, which extends through the third cutter fixing plate along the arrangement direction of the cutter connecting assembly 43 and the third cutter fixing plate. The cutter drive member 421 can extend from the clearance hole into the space between the first cutter fixing plate and the second cutter fixing plate to connect the cutter floating block 423; alternatively, the cutter floating block 423 located between the first cutter fixing plate and the second cutter fixing plate can pass through the third cutter fixing plate from the clearance hole to connect the cutter drive member 421; alternatively, both the cutter floating block 423 located between the first cutter fixing plate and the second cutter fixing plate and the cutter drive member 421 can extend into the clearance hole and be connected within the clearance hole.

[0080] Furthermore, when the cutter floating block 423 is away from the cutter connecting assembly 43, the cutter floating block 423 actually abuts against the third cutter fixing plate, thereby abutting against the cutter fixing block 422.

[0081] In one embodiment, both the first cutter fixing plate and the second cutter fixing plate can be connected to the cutter connecting plate and located on the side of the cutter holder connecting plate 4311 away from the cutter holder 432.

[0082] In one embodiment, the cutter drive unit 421 includes a cutter drive cylinder. The cylinder body of the cutter drive cylinder is connected to the cutter support frame 41, and the piston rod of the cutter drive cylinder is connected to the cutter floating block 423. During operation, the cutter drive cylinder is used to drive the cutting blade 44 to reciprocate along the height direction of the cutting blade 44.

[0083] In one embodiment, the cutter drive unit 421 includes a plurality of cutter drive cylinders, each of which can simultaneously drive the cutting blade 44 to move closer to the support table and simultaneously drive the cutting blade 44 away from the support table.

[0084] In one embodiment, multiple first cutter drive components 42, cutter connection components 43, and cutting blades 44 are provided and correspond one-to-one; the first cutter drive components 42 and their corresponding cutter connection components 43 and cutting blades 44 are connected to form a cutter module; each cutter module is spaced apart along the thickness direction of the cutting blade 44; each cutter module is provided with a cutting depth limiting member 45.

[0085] During operation, each cutting module can be equipped with different types of cutting blades 44, and the operation of the corresponding cutting module can be controlled according to the cutting needs, so as to cut the film material through that cutting module. In addition, each cutting can be carried out by cutting the film material using only one cutting module.

[0086] like Figure 1 As shown, in one embodiment, the cutter support frame 41 includes a first cutter support plate 411, a second cutter support plate 412, and a third cutter support plate 413; wherein the first cutter support plate 411 and the second cutter support plate 412 are both disposed on the third cutter support plate 413 and are spaced apart, and the first cutter support plate 411 and the second cutter support plate 412 are both located on the side of the third cutter support plate 413 closest to the support platform. In this case, the cutter support frame 41 is generally U-shaped, and it is a gantry frame.

[0087] The first cutter support plate 411 is connected to the support platform at one end away from the third cutter support plate 413, and the second cutter support plate 412 is also connected to the support platform at one end away from the third cutter support plate 413. The first cutter drive assembly 42 is connected to the third cutter support plate 413, and the cutter connection assembly 43 is located between the first cutter support plate 411 and the second cutter support plate 412.

[0088] In one embodiment, when the first cutter drive assembly 42 includes a cutter drive cylinder, the cylinder body of the cutter drive cylinder may be connected to the side of the third cutter support plate 413 opposite to the first cutter support plate 411, and the piston rod of the cutter drive cylinder may pass through the third cutter support plate 413 from the corresponding window on the third cutter support plate 413 and be connected to the cutter connection assembly 43.

[0089] like Figure 1 and Figure 2 As shown, in one embodiment, the cutting device 4 further includes a second cutter drive assembly 46, which is connected to the support platform, and the cutter support frame 41 is connected to the second cutter drive assembly 46; the second cutter drive assembly 46 is used to drive the cutter support to reciprocate along the thickness direction of the cutting blade 44.

[0090] This allows the cutter support 41 to be moved to the appropriate position as needed, so that the cover film of the appropriate length can be cut.

[0091] In one embodiment, the second cutter drive assembly 46 may include components such as a linear motor. During operation, the linear motor can drive the cutter support frame 41 to reciprocate along the thickness direction of the cutter 44.

[0092] In other embodiments, the second cutter drive assembly 46 may also be a combination of components such as a rotary motor and a lead screw mechanism, or a combination of components such as a rotary motor and a rack and pinion mechanism, or other devices capable of driving linear motion of an object.

[0093] like Figure 1 As shown, in one embodiment, the cutting device 4 further includes a cutting positioning camera 47, which is connected to the cutter support frame 41 and is used to identify the distance that the cutter support frame 41 moves along the thickness direction of the cutter 44.

[0094] During operation, the cutting positioning camera 47 can capture images of markers on the film material, thereby identifying the movement distance of the cutter support. These markers can be placed on the base paper or the cover film. Furthermore, the markers can be evenly spaced along the length of the film material, where the length direction of the unwound film material can be a primary direction.

[0095] Of course, in other embodiments, the marker may also be placed on the support platform, or placed on the support platform.

[0096] This utility model embodiment also provides a film applicator, which includes a support platform and a cutting device 4 as described in any of the above embodiments. The cutting device 4 is connected to the support platform and is used to cut the film material placed on the support platform.

[0097] In one embodiment, all cutting devices 4 are connected above the support platform.

[0098] In one embodiment, the support platform has a film material support surface, which is flat and located below the cutting blade 44. When the film material is placed on the film material support surface, it is placed on the support platform. When the cutting depth limiting member 45 abuts against the support platform, it actually abuts against the film material support surface.

[0099] In this scenario, along the direction from the back of the blade 441 to the cutting edge 442, the cutting depth limiting member 45 protrudes from the cutting blade 44, and the length of the cutting depth limiting member 45 protruding from the cutting blade 44 is less than the thickness of the backing paper. During operation, when the cutting depth limiting member 45 abuts against the film support surface, the cutting blade 44 can cut the cover film of the film on the film support surface without cutting the backing paper of the film.

[0100] It should be understood that the “length of the cutting depth limiting member 45 protruding from the cutting blade 44” mentioned above refers to the length of the portion of the cutting depth limiting member 45 protruding from the cutting blade 44 in the vertical direction (i.e., the arrangement direction of the back of the blade 441 and the cutting blade 442) along the direction from the back of the blade 441 to the cutting edge 442.

[0101] In addition, since the cutting depth limiting member 45 protrudes from the cutting blade 44 along the direction from the back of the blade 441 to the cutting edge 442, the cutting depth limiting member 45 can also shield and protect the cutting edge 442 of the cutting blade 44, effectively preventing it from colliding with foreign objects.

[0102] In other embodiments, when the cutting depth limiting member 45 protrudes from the cutting blade 44 along the direction from the back of the blade 441 to the cutting edge 442, the length of the cutting depth limiting member 45 protruding from the cutting blade 44 can also be set in other ways, for example, it can be greater than the thickness of the backing paper.

[0103] In other embodiments, the cutting blade 44 may protrude from the cutting depth limiting member 45 along the direction from the back of the blade 441 to the cutting edge 442. In this case, the length of the cutting blade 44 protruding from the cutting depth limiting member 45 can be set according to actual needs, and this embodiment does not make a specific limitation.

[0104] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
