Abstract
Description
Technical Field
[0001] This utility model relates to the field of circuit board production equipment, and in particular to a film removal 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 attached to the base paper to form the film stock, which is then wound into a roll. During production, the roll is usually unwound using a corresponding unwinding module, and then cut by a film cutting machine to obtain the required length of cover film (defined as a film unit). Subsequently, a film removal device removes the film unit from the base paper and applies it to the FPC. Additionally, a corresponding rewinding module is needed to rewind the base paper during production.
[0004] However, in actual production, the film-removing module of the laminating machine may fail to remove the film unit from the backing paper due to the tight adhesion between the cover film and the backing paper, which is detrimental to subsequent production. Utility Model Content

[0049] Membrane taking device 5
[0050] like Figure 1As shown, in one embodiment, the film taking device 5 is used to separate the cover film and the backing paper of the film material. In normal film material, the cover film is usually covering the backing paper, and the target object can be FPC, etc.
[0051] In addition, the film taking device 5 includes a frame 50, a pre-peeling module 51, and a film taking module 52; both the pre-peeling module 51 and the film taking module 52 are connected to the frame 50; the pre-peeling module 51 can bend the backing paper by wrapping it around it, and can apply force to the cover film on the backing paper at the bend; the film taking module 52 is used to grab the cover film output from the pre-peeling module 51, so as to cooperate with the pre-peeling module 51 to separate the cover film and the backing paper.
[0052] In use, the backing paper with the covering film can be manually wrapped around the pre-peeling module 51, with the covering film located on the side of the backing paper away from the pre-peeling module 51. Furthermore, the installation operation can be performed by bending the backing paper in the direction away from the covering film. This applies force to the covering film at the bend of the backing paper, which helps to separate the covering film from the backing paper, thus making it easier for the film removal module 52 to remove the covering film from the backing paper.
[0053] The frame 50 is used to support the pre-peeling module 51 and the film-taking module 52, which can be placed on the ground.
[0054] Pre-stripping module 51
[0055] like Figures 2 to 4 As shown, in one embodiment, the pre-peeling module 51 includes a peeling blade 511, a pre-peeling support frame 512, and a first pre-peeling drive assembly 514; the pre-peeling support frame 512 is connected to the first pre-peeling drive assembly 514; the peeling blade 511 is connected to the pre-peeling support frame 512 and can bend the backing paper; the first pre-peeling drive assembly 514 can drive the peeling blade 511 to reciprocate along a first direction, so that the peeling blade can apply force to the cover film on the side of the backing paper away from the cover film, thereby facilitating the film removal module 52 to remove the cover film from the backing paper.
[0056] exist Figure 1 and Figure 2 Of the directions shown, the first direction is parallel to the X-axis, and the first direction can be a front-back direction.
[0057] When the first pre-peeling drive assembly 514 drives the peeling blade 511 to move in the first direction, the peeling blade 511 can move to the edge of the cover film. Since the backing paper is bent at the peeling blade 511, the peeling blade 511 can apply a force to the backing paper toward the cover film, thereby applying a force to the edge of the cover film along the direction from the backing paper to the cover film. This can separate the edge of the cover film from the backing paper, which helps to reduce the adhesive force between the cover film and the backing paper, thus making it easier for the film removal module 52 to remove the cover film from the backing paper.
[0058] Moreover, during operation, the peeling blade 511 can be driven forward to the front edge of the cover film; then, the peeling blade 511 can be driven to reciprocate along the first direction to rub up the front edge of the cover film, so that the front edge of the cover film is separated from the backing paper; then, the cover film can be picked up by the film-grabbing module 52; then, the peeling blade 511 moves relative to the film material from front to back until it reaches the rear edge of the cover film. During this process, the peeling blade 511 can continuously apply force to the front edge of the area where the cover film contacts the backing paper, which is conducive to the separation of the cover film from the backing paper. During this process, the film-grabbing module 2 can move forward or not.
[0059] Furthermore, the movement of the stripper 511 relative to the film material from front to back can mean: the film material remains stationary, but the stripper 511 moves from front to back; or, the stripper 511 remains stationary, but the film material moves from back to front (such as the process of unwinding the film material by the unwinding module 58 and rewinding the film material by the rewinding module 59 described below); or, the film material moves from back to front, and the stripper 511 moves from front to back.
[0060] In addition, "the first pre-peeling drive assembly 514 drives the peeling blade 511 to reciprocate along the first direction" can mean that the first pre-peeling drive assembly 514 drives the pre-peeling support frame 512 to reciprocate along the first direction, thereby driving the peeling blade 511 to reciprocate along the first direction.
[0061] In addition, "the cover film output from the pre-peeling module 51" can refer to the cover film whose edges are rubbed up by the pre-peeling module 51.
[0062] like Figure 3 As shown, in one embodiment, the peeling blade 511 can be a triangular prism structure, and its cross-section can be a right triangle or an isosceles triangle, etc. During operation, the backing paper can be bent at one of its edges (defined as the front edge, which can be located at the very front end of the peeling blade 511). Of course, in other embodiments, the cross-section of the peeling blade 511 can also be a prism structure of other shapes, or the peeling blade 511 can also be a cylindrical structure, etc.
[0063] In addition, the aforementioned drive pre-peeling support frame 512 moves the peeling blade 511 to the edge of the covering film, which mainly refers to moving the front edge of the peeling blade 511 to the edge of the covering film.
[0064] The pre-peeling module 51 is wrapped around the base paper to bend it. This can mean that the base paper is wrapped around the peeling blade 511 so that it is bent at the edge of the peeling blade. Moreover, when the base paper is wrapped around the peeling blade 511, a portion of the base paper can be located above the peeling blade 511, and the base paper is bent downward at the front edge of the peeling blade 511.
[0065] exist Figure 2 In the directions shown, the vertical direction is parallel to the Z-axis.
[0066] like Figure 1 As shown, in one embodiment, the pre-peeling module 51 further includes a pre-peeling guide 513, which is connected to the pre-peeling support frame 512 and spaced apart from the peeling blade 511. The peeling blade 511 can bend the backing paper passing between the peeling blade 511 and the pre-peeling guide 513. In use, the backing paper can first pass around the peeling blade 511, then extend between the peeling blade 511 and the pre-peeling guide 513, and then pass around the pre-peeling guide 513, wherein the peeling blade 511 and the pre-peeling guide 513 can bend the backing paper into a Z-shape.
[0067] Additionally, during use, the backing paper can be manually passed between the peeling blade 511 and the pre-peeling guide 513, with the peeling blade 511 positioned on the side of the backing paper away from the cover film. Simultaneously, the length of the backing paper should be greater than the length of the cover film (i.e., a portion of the backing paper is not covered by the cover film), so that when the backing paper bends at the peeling blade 511, the cover film will not bend at the peeling blade 511. When the first pre-peeling drive assembly 514 drives the peeling blade 511 to move in the first direction, the peeling blade 511 can be moved to the edge of the cover film.
[0068] In one embodiment, the pre-peeling guide 513 is rotatable about its own axis relative to the pre-peeling support 512; the axis of the pre-peeling guide 513 is parallel to the second direction. This reduces friction between the pre-peeling guide 513 and the film material.
[0069] The pre-stripping guide 513 can be a cylindrical structure with pre-stripping support frame 512 connected to both ends.
[0070] Additionally, the pre-peeling guide 513 can be located below the peeling blade 511, with the two spaced apart in the vertical direction. In this case, the film material can be bent downwards at the peeling blade 511 to wrap around the pre-peeling guide 513. Figure 2 In the direction shown, the film material extends forward (i.e., along the direction of the arrow on the X-axis), bends downward at the front end of the peeling blade 511, and wraps around the pre-peeling guide 513. After wrapping around the pre-peeling guide 513, the film material (actually the backing paper) continues to extend forward.
[0071] like Figure 2 As shown, in one embodiment, multiple pre-peeling guides 513 are provided, and the multiple pre-peeling guides 513 are arranged sequentially and spaced apart below the peeling blade 511 in a vertical direction. When the backing paper passes between the peeling blade 511 and the different pre-peeling guides 513, the bending angle of the backing paper is different. This allows the bending angle of the backing paper to be adjusted according to actual needs, improving the separation effect between the cover film and the backing paper.
[0072] Among them, Figure 2 In the example shown, there are two pre-stripping guides 513.
[0073] Furthermore, the first direction, the second direction, and the up / down direction are all perpendicular to each other. In this case, the first direction can be front / back, and the second direction can be left / right. Figure 1 Of the directions shown, the second direction is parallel to the Y-axis.
[0074] In one embodiment, the first pre-peeling drive assembly 514 may be a drive system capable of driving linear motion of an object, comprising components such as a rotary motor, a lead screw transmission mechanism, and a guide mechanism; or, the first pre-peeling drive assembly 514 may also be a device capable of driving linear motion of an object, such as a linear motor.
[0075] like Figure 2 and Figure 3 As shown, in one embodiment, the pre-peeling module 51 further includes a pre-peeling platform 515, which is disposed on the pre-peeling support frame 512; the pre-peeling platform 515 and the peeling blade 511 are arranged along a first direction; the pre-peeling platform 515 is used to support the film material. This can improve the support effect on the film material.
[0076] Furthermore, the pre-peeling platform 515 is also used in conjunction with the cutting device 60, so that the cutting device 60 can cut the cover film of the film material placed on the pre-peeling platform 515, and the film taking module 52 can take away the cover film of the required length.
[0077] like Figure 1 As shown, in one embodiment, the pre-peeling platform 515 has a pre-peeling support surface 5151, and the film material placed on the pre-peeling platform 515 is actually placed on the pre-peeling support surface 5151.
[0078] In some scenarios, the pre-peeling support surface 5151 is the upper surface of the pre-peeling platform 515. Moreover, the pre-peeling support surface 5151 can be a plane. At the same time, when the module is placed on the pre-peeling support surface 5151, the backing paper of the portion of the film material located on the pre-peeling support surface 5151 can be located between the cover film of that portion of the film material and the pre-peeling support member 51b2.
[0079] In the embodiment where the peeling blade 511 is a triangular prism, one side of the peeling blade 511 may be flush with the pre-peeling support surface 5151. The other sides of the peeling blade 511 and the two end faces in the axial direction are all located below this side. In use, the backing paper passes around the edge of the triangular prism from this side.
[0080] like Figure 3As shown, in one embodiment, the pre-peeling module 51 further includes a first pre-peeling pressing member 516 and a pre-peeling pressing drive member 517; the pre-peeling pressing drive member 517 is connected to the pre-peeling support frame 512 and connected to the first pre-peeling pressing member 516; the pre-peeling pressing drive member 517 is used to drive the first pre-peeling pressing member 516 so that the first pre-peeling pressing member 516 can cooperate with the pre-peeling platform 515 to clamp or release the film material placed on the pre-peeling platform 515.
[0081] like Figure 1 As shown, when the pre-peeling module 51 is applied to the laminating machine, it can cooperate with the film unwinding module 58 and the film rewinding module 59. The incoming film material is usually a roll. The film unwinding module 58 is used to unwind the film roll, and the film rewinding module 59 is used to rewind the backing paper. Moreover, the film unwinding module 58 and the film rewinding module 59 are spaced apart along the first direction, and the pre-peeling module 51 is located between them. The film unwinding module 58 will be placed on the pre-peeling platform 515. During operation, after the film unwinding module 58 unwinds a certain length of film, the pre-peeling pressing drive 517 can drive the first pre-peeling pressing component 516 to approach the pre-peeling platform 515 to clamp the film. Then, the first pre-peeling drive assembly 514 can drive the pre-peeling support frame 512 to move a predetermined distance along the first direction. Then, the cutting device 60 cuts the cover film to obtain film units, so that the length of the cut film units can meet the requirements.
[0082] In existing technologies, the length of the unwound film is typically calculated by the number of rotations of the unwinding module 58, and then used as the basis for the length of the film unit cut by the cutting device 60. However, as the unwinding operation progresses, the diameter of the film roll continuously decreases, and the length of the unwound film per rotation also continuously decreases, resulting in errors in calculating the length of the film unit. The design of this embodiment allows for a more accurate calculation of the unwound film length, thereby improving the precision of the length of the cut film unit.
[0083] Furthermore, the cutting position of the cutting device 60 can be located between the first pre-peeling pressing member 516 and the peeling blade 511. The cutting device 60 includes a cutting drive module and a cutting blade. The cutting drive module can drive the cutting blade to move up and down, allowing the cutting blade to approach or move away from the pre-peeling platform 515. When the cutting blade moves downwards towards the pre-peeling platform 515, it can cut the cover film of the film material placed on the pre-peeling support surface 5151. Moreover, by controlling the cutting depth, the cutting blade can cut only the cover film without cutting the backing paper. The cutting device 60 can adopt an existing design.
[0084] In one embodiment, in the first direction, the peeling blade 511 may be located between the pre-peeling platform 515 and the film winding module 59, and the first pre-peeling pressing member 516 may be located between the peeling blade 511 and the film unwinding module 58. Moreover, in the first direction, the first pre-peeling pressing member 516 is spaced apart from the peeling blade 511.
[0085] In one embodiment, the first pre-peeling pressing member 516 may be a pressure plate, and the pre-peeling pressing drive member 517 may be a cylinder. The first pre-peeling pressing member 516 presses the film material onto the pre-peeling platform 515, which actually means that the first pre-peeling pressing member 516 presses the film material onto the pre-peeling support surface 5151.
[0086] Of course, in other embodiments, the pre-peeling pressing drive 517 may also be a device such as an electric cylinder that can drive the first pre-peeling pressing member 516 to move linearly.
[0087] In one embodiment, the first pre-peeling pressing member 516 is located above the pre-peeling platform 515; the pre-peeling pressing drive member 517 is located below the pre-peeling platform 515 and is used to drive the first pre-peeling pressing member 516 to move up and down; the first direction is perpendicular to the up and down direction. This makes it easier to install and arrange the pre-peeling module 51 and helps to reduce the space occupied by the pre-peeling module 51.
[0088] In addition, the pre-peeling platform 515 may be provided with a clearance hole, and the pre-peeling pressing drive 517 may pass through the pre-peeling platform 515 from the clearance hole to connect the first pre-peeling pressing member 516.
[0089] In one embodiment, the pre-peeling module 51 may include two pre-peeling pressing drive members 517, which may be spaced apart along a second direction and used to simultaneously drive the first pre-peeling pressing member 516 to move. During operation, the film material may pass between the two pre-peeling pressing drive members 517.
[0090] like Figure 2 and Figure 3 As shown, in one embodiment, the pre-peeling module 51 further includes a pre-peeling air blowing assembly 518, which is connected to the pre-peeling support frame 512 and is capable of blowing up the cover film on the backing paper bent by the peeling blade 511. Specifically, the pre-peeling air blowing assembly 518 can blow air onto the cover film on the backing paper that has passed through the peeling blade 511 along the direction from the pre-peeling guide 513 to the peeling blade 511. This arrangement facilitates the separation of the cover film from the backing paper.
[0091] like Figure 3As shown, in one embodiment, the pre-peeling air blowing assembly 518 includes an air outlet duct 5181, which is used to connect to the source and to blow air onto the film material. In a first direction, the air outlet duct 5181 is located between the peeling blade 511 and the film unwinding module 58; in the vertical direction, the air outlet duct 5181 is located below the peeling blade 511; the air outlet duct 5181 extends along a second direction and has an air outlet hole, through which gas in the air outlet duct 5181 can flow out and blow the cover film.
[0092] Specifically, the air outlet extends from the outer side of the air outlet pipe 5181 to the inner surface of the air outlet pipe 5181.
[0093] In one embodiment, there may be multiple air outlets, which are spaced apart along the length of the air outlet duct 5181. Alternatively, the air outlets may be elongated slot structures that extend along the length of the air outlet duct 5181.
[0094] like Figure 3 and Figure 4 As shown, in one embodiment, the pre-peeling module 51 further includes a second pre-peeling drive assembly 519 and a pre-peeling drive roller 51a; the second pre-peeling drive assembly 519 and the pre-peeling drive roller 51a are both connected to the pre-peeling support frame 512; the second pre-peeling drive assembly 519 is used to drive the pre-peeling drive roller 51a to rotate, so that the pre-peeling drive roller 51a can drive the film material wound on the pre-peeling drive roller 51a.
[0095] The second pre-peeling drive assembly 519 driving the pre-peeling drive roller 51a to rotate actually means that the second pre-peeling drive assembly 519 provides driving force to the pre-peeling drive roller 51a, enabling the pre-peeling drive roller 51a to rotate around its own axis.
[0096] In addition, the axis of the pre-peeling drive roller 51a can be parallel to the second direction.
[0097] During operation, the backing paper can be wound around the pre-peeling drive roller 51a. When the pre-peeling drive roller 51a rotates, it can increase the driving force for unwinding the film material and also accelerate the separation of the cover film and the backing paper.
[0098] In one embodiment, the second pre-peeling drive assembly 519 may include a rotary motor and a synchronous belt drive mechanism. The cylinder of the rotary motor may be connected to the pre-peeling support frame 512, and the motor shaft of the rotary motor may be connected to the driving pulley of the synchronous belt drive mechanism. The driven pulley of the synchronous belt drive mechanism may be connected to the pre-peeling drive roller 51a. In this way, the driving force of the rotary motor can be transmitted to the pre-peeling drive roller 51a through the synchronous belt drive mechanism, thereby driving the pre-peeling drive roller 51a to rotate.
[0099] Of course, in other embodiments, the second pre-peeling drive assembly 519 may include a rotary motor but not a synchronous belt drive mechanism. In this case, the motor shaft of the rotary motor may be directly connected to the pre-peeling drive roller 51a. Furthermore, in other embodiments, the rotary motor may be connected to the pre-peeling drive roller 51a via a speed reducer or the like.
[0100] In one embodiment, the pre-peeling drive roller 51a is located below the peeling blade 511 and on the side of the peeling blade 511 close to the pre-peeling platform 515. Specifically, in the first direction, the pre-peeling drive roller 51a may be located between the peeling blade 511 and the first pre-peeling pressing member 516. Furthermore, in the first direction, the rotation motor of the second pre-peeling drive assembly 519 may be located between the pre-peeling drive roller 51a and the first pre-peeling pressing member 516.
[0101] like Figure 4 As shown, in one embodiment, the pre-peeling module 51 further includes a third pre-peeling drive assembly 51b and a second pre-peeling pressing member 51c; the third pre-peeling drive assembly 51b is connected to the pre-peeling support frame 512 and connected to the second pre-peeling pressing member 51c; the third pre-peeling drive assembly 51b is used to drive the second pre-peeling pressing member 51c closer to or further away from the pre-peeling drive roller 51a, so that the second pre-peeling pressing member 51c and the pre-peeling drive roller 51a can clamp or release the backing paper. This arrangement can improve the driving force of the pre-peeling drive roller 51a on the film material.
[0102] In one embodiment, in the first direction, the second pre-peeling pressing member 51c is located on the side of the pre-peeling drive roller 51a away from the peeling knife 511, and the third pre-peeling drive assembly 51b can drive the second pre-peeling pressing member 51c to reciprocate along the first direction, so that the second pre-peeling pressing member 51c can move closer to or further away from the pre-peeling drive roller 51a.
[0103] When the second pre-peeling pressing member 51c approaches the pre-peeling drive roller 51a, the second pre-peeling pressing member 51c and the pre-peeling drive roller 51a can clamp the bottom paper located between them; when the second pre-peeling pressing member 51c moves away from the pre-peeling drive roller 51a, the second pre-peeling pressing member 51c and the pre-peeling drive roller 51a can release the bottom paper located between them.
[0104] In one embodiment, the second pre-peeling pressing member 51c is rotatable about its own axis relative to the third pre-peeling driving assembly 51b; the axis of the second pre-peeling pressing member 51c is parallel to the axis of the pre-peeling driving roller 51a and parallel to the second direction. This reduces the friction between the second pre-peeling pressing member 51c and the backing paper. The third pre-peeling driving assembly 51b may be a cylindrical structure.
[0105] like Figure 4As shown, in one embodiment, the third pre-peeling drive assembly 51b includes a pre-peeling drive member 51b1 and a pre-peeling support member 51b2. The pre-peeling drive member 51b1 is connected to the pre-peeling support frame 512 and the pre-peeling support member 51b2. The second pre-peeling pressing member 51c is connected to the pre-peeling support member 51b2. The pre-peeling drive member 51b1 drives the pre-peeling support member 51b2 to move, thereby driving the second pre-peeling pressing member 51c to move.
[0106] In one embodiment, the pre-peeling drive member 51b1 is a pre-peeling drive cylinder, the pre-peeling support member 51b2 is a pre-peeling support block, and the second pre-peeling pressing member 51c may be rotatably connected to the pre-peeling support block. Furthermore, there are two pre-peeling drive members 51b1 and two pre-peeling support members 51b2, with each pre-peeling drive member 51b1 connecting to its corresponding pre-peeling support member 51b2. The two ends of the second pre-peeling pressing member 51c are respectively connected to the two pre-peeling support members 51b2.
[0107] like Figure 2 and Figure 3 As shown, in one embodiment, the pre-peeling support frame 512 includes a first pre-peeling support plate 5121, a second pre-peeling support plate 5122, and a third pre-peeling support plate 5123; the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122 are spaced apart along a second direction and are both connected to the first pre-peeling drive assembly 514; the two ends of the third pre-peeling support plate 5123 are respectively connected to the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122, and the peeling blade 511 and the pre-peeling guide 513 can both be connected to the third pre-peeling support plate 5123.
[0108] Furthermore, the two ends of the pre-peeling platform 515 are respectively connected to the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122, and are located above the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122. The second pre-peeling drive assembly 519 is located below the pre-peeling platform 515. Moreover, after assembly, the third pre-peeling support plate 5123 can also be located below the pre-peeling platform 515.
[0109] The second pre-peeling drive assembly 519, the third pre-peeling drive assembly 51b, and the pre-peeling drive roller 51a can be connected to either the first pre-peeling support plate 5121 or the second pre-peeling support plate 5122.
[0110] Furthermore, the pre-peeling pressing drive 517 may be located between the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122, so that the pre-peeling pressing drive 517 is shielded and protected by the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122. Alternatively, the pre-peeling pressing drive 517 may not be located between the first pre-peeling support plate 5121 and the second pre-peeling support plate 5122.
[0111] Membrane taking module 52
[0112] like Figure 1 As shown, in one embodiment, the film-taking module 52 includes a film-coating adsorption component 521 and a film-coating driving component 522; the film-coating driving component 522 is connected to the frame 50; the film-coating adsorption component 521 is connected to the film-coating driving component 522; the film-coating adsorption component 521 is used for vacuum adsorption of the film; the film-coating driving component 522 can drive the film-coating adsorption component 521 to move in the up-down direction to approach or move away from the pre-peeling module 51; the first direction is perpendicular to the up-down direction.
[0113] Specifically, when the film adsorption assembly 521 moves downward, it can approach the pre-peeling module 51 so as to vacuum adsorb the film on the pre-peeling module 51.
[0114] During operation, the pre-peeling platform 515 can be driven to move to a suitable position along the first direction by the first pre-peeling drive component 514, so that when the film-coating drive component 522 drives the film-coating adsorption component 521 to move downward, it can come into contact with the covering film, so that the film-coating adsorption component 521 can adsorb the covering film.
[0115] In one embodiment, the film-coated adsorption component 521 has a negative pressure hole, and the negative pressure hole is connected to a negative pressure device. When the negative pressure device is working, a negative pressure can be generated at the negative pressure hole, thereby adsorbing the film.
[0116] The film-coated adsorption assembly 521 includes a film-coated adsorption plate. Multiple negative pressure holes are provided on the lower surface of the film-coated adsorption plate. These negative pressure holes can be arranged in an array on the lower surface of the film-coated adsorption plate. When the negative pressure device is working, each negative pressure hole on the film-coated adsorption plate can generate negative pressure. Furthermore, the lower surface of the film-coated adsorption plate can be a plane, and it can be perpendicular to the vertical direction. Alternatively, in other embodiments, the film-coated adsorption assembly 521 can also include a film-coated support member and a covering vacuum suction cup disposed on the film-coated support member. Each vacuum suction cup has negative pressure holes, and each vacuum suction cup is connected to the negative pressure device. When the negative pressure device is working, each vacuum suction cup can generate negative pressure.
[0117] In one embodiment, the coating drive assembly 522 may be a drive system that can drive the linear motion of an object, consisting of components such as a rotary motor, a lead screw transmission mechanism, and a guide mechanism; or, the coating drive assembly 522 may be a device that can drive the linear motion of an object, such as a cylinder or a linear motor.
[0118] like Figure 1 and Figure 7As shown, in one embodiment, the film-taking module 52 further includes a film-pulling assembly 55 and a transfer platform 56; both the film-pulling assembly 55 and the transfer platform 56 are connected to the frame 50; the film-pulling assembly 55 can clamp the cover film output by the pre-peeling module 51 and is used to pull the cover film onto the transfer platform 56; the film-taking module 52 can grab the cover film on the transfer platform 56.
[0119] The pre-peeling module 51 primarily applies force to the edge of the contact area between the cover film and the backing paper to separate them. When the pre-peeling module 51 cooperates with the film-taking module 52, the pre-peeling module 51 first moves the film material along the first direction to approach the film-taking module 52; then, the film-adsorption component 521 grabs (adsorbs) the cover film; then the pre-peeling module 51 moves along the first direction and away from the film-adsorption component 521. During this process, the peeling blade 511 can apply force to the edge of the area where the cover film contacts the backing paper. In this way, as the pre-peeling module 51 moves away from the film-adsorption component 521, the cover film gradually separates from the backing paper, and after the cover film is separated from the backing paper, it is grabbed by the film-taking module, which can improve production efficiency.
[0120] However, in some scenarios, the cut cover film does not need to be completely separated from the backing paper. For example, initially, there is no cutout area on the cover film, but if a cutout area is required on the film unit when covering the target object, the cover film needs to be cut before separation so that the separated film unit has the required cutout structure. In this case, after the film unit is removed, the part of the cover film corresponding to the cutout structure (defined as the waste film unit) still needs to remain on the backing paper.
[0121] In this scenario, if the pre-peeling module 51 and the film-coating adsorption component 521 are used together to separate the covering film, the film-coating adsorption component 521 will easily remove the waste unit and the film unit from the backing paper at the same time. When the film unit is subsequently covered on the target object, the waste unit will also be placed on the target object, which will have an adverse effect on subsequent production.
[0122] In this scenario, the separation of the film unit can be achieved by using a pre-peeling module 51, a film-pulling assembly 55, and a transfer platform 56 in combination. Specifically, after the pre-peeling module 51 lifts the edge of the cover film to separate it from the backing paper, the film-pulling assembly 55 can be used to clamp the edge of the cover film. Then, the film-pulling assembly 55 is driven to move, so that the clamped cover film moves towards the transfer platform 56, and finally the required portion of the cover film (i.e., the film unit) is pulled onto the transfer platform 56, thereby achieving the separation of the film unit from the backing paper. In this operation, the film-pulling assembly 55 does not clamp the waste unit; therefore, the waste unit will not separate from the backing paper when separating the film unit.
[0123] In addition, when the film pulling assembly 55 pulls the film onto the transfer platform 56, the pre-peeling platform 515 may remain stationary, and the first pre-peeling pressing member 516 and the pre-peeling platform 515 also release the film material. At the same time, the film unwinding module 58 unwinds the film material, and the film winding module 59 winds up the film material.
[0124] In subsequent work, the membrane retrieval module 52 can retrieve membrane units from the transfer platform 56.
[0125] It should be understood that the cover membrane pulled to the transfer platform 56 by the membrane assembly 55 is the membrane unit.
[0126] As can be seen, through the settings of this embodiment, the film-taking module 52 can adapt to different cover film separation requirements, thereby improving the adaptability of the film-taking module 52.
[0127] In one embodiment, in a first direction, both the film-stretching assembly 55 and the transfer platform 56 are located between the pre-peeling platform 515 and the second film-coating clamping assembly 54.
[0128] like Figure 7 As shown, in one embodiment, the film-pulling assembly 55 includes a film-pulling clamping component 551 and a film-pulling driving component 552; the film-pulling driving component 552 is connected to the frame 50 and connected to the film-pulling clamping component 551, and is used to drive the film-pulling clamping component 551 to approach or move away from the pre-peeling module 51; wherein, when the film-pulling clamping component 551 approaches the pre-peeling module 51, it can clamp the cover film; when the film-pulling clamping component 551 moves away from the pre-peeling module 51, it can pull the film unit onto the transfer platform 56.
[0129] The membrane pulling drive component 552 is used to drive the membrane pulling clamping component 551 to reciprocate along the first direction.
[0130] In one embodiment, the film-pulling clamping component 551 includes a film-pulling clamping drive component 5511, a first film-pulling clamping plate 5512, and a second film-pulling clamping plate 5513.
[0131] The film-stretching clamping drive 5511 can drive at least one of the first film-stretching clamping plate 5512 and the second film-stretching clamping plate 5513 to move, thereby increasing or decreasing the distance between the first film-stretching clamping plate 5512 and the second film-stretching clamping plate 5513. When the distance between the first film-stretching clamping plate 5512 and the second film-stretching clamping plate 5513 increases, the film material between them can be released; when the distance between the first film-stretching clamping plate 5512 and the second film-stretching clamping plate 5513 decreases, the film material between them can be clamped.
[0132] In one embodiment, the film-pulling clamping drive 5511 includes a gripper cylinder connected to the film-pulling drive component 552 and connected to a first film-pulling clamping plate 5512 and a second film-pulling clamping plate 5513. The gripper cylinder can simultaneously drive the first film-pulling clamping plate 5512 and the second film-pulling clamping plate 5513 to move, so that the first film-pulling clamping plate 5512 and the second film-pulling clamping plate 5513 move closer to each other or further away from each other, so as to clamp or release the film material located between them.
[0133] In addition, the gripper cylinder can drive the first film-stretching clamping plate 5512 and the second film-stretching clamping plate 5513 to move up and down, so that the two move closer to each other or further apart. The first film-stretching clamping plate 5512 can be located below the second film-stretching clamping plate 5513, or the first film-stretching clamping plate 5512 can be located above the second film-stretching clamping plate 5513.
[0134] Furthermore, the film-pulling clamping component 551 and the first film-coating clamping assembly 53 adopt the same structural configuration. Moreover, the film-pulling clamping component 551 can also adopt other existing configurations capable of clamping or releasing the film material, and this embodiment does not impose any restrictions on it.
[0135] In one embodiment, the membrane stretching drive component 552 may be a drive system that can drive the linear motion of an object, consisting of components such as a rotary motor, a lead screw transmission mechanism, and a guide mechanism; or, the membrane stretching drive component 552 may also be a device that can drive the linear motion of an object, such as a cylinder or a linear motor.
[0136] In one embodiment, the film pulling drive component 552 is provided with a clearance space, so that when the film pulling drive component 552 drives the film pulling clamping component 551 to approach or move away from the pre-peeling module, it avoids the transfer platform 56.
[0137] That is, the film pulling drive component 552 drives the film pulling clamping component 551 to approach or move away from the pre-peeling module, which can result in an overlap with the transfer platform 56. This can reduce the size of the entire film taking device 5 in the direction of the film clamping component approaching or moving away from the pre-peeling module.
[0138] In addition, the direction in which the membrane clamping assembly approaches or moves away from the pre-peeling module is the first direction.
[0139] like Figure 7 As shown, in one embodiment, the film-pulling drive component 552 includes a film-pulling drive mechanism 5521 and a film-pulling support frame 5522. The film-pulling support frame 5522 is connected to the film-pulling drive mechanism 5521, and the film-pulling clamping component 551 is connected to the film-pulling support frame 5522. The film-pulling drive mechanism 5521 drives the film-pulling support frame 5522 to reciprocate along a first direction, thereby driving the film-pulling clamping component 551 to reciprocate along the first direction.
[0140] The membrane stretching drive mechanism 5521 can be the aforementioned drive system that can drive the linear motion of an object, consisting of components such as a rotary motor, a lead screw transmission mechanism, and a guide mechanism; or, the membrane stretching drive mechanism 5521 can be a device such as a cylinder or a linear motor that can drive the linear motion of an object.
[0141] like Figure 7 As shown, the membrane support frame 5522 includes a first membrane support plate 5523, a second membrane support plate 5524, and a third membrane support plate 5525. The first membrane support plate 5523 and the second membrane support plate 5524 are spaced apart on the third membrane support plate 5525 along a second direction, and the first membrane support plate 5523 and the second membrane support plate 5524 are located on the same side of the third membrane support plate 5525 in the vertical direction. The first membrane support plate 5523, the second membrane support plate 5524, and the third membrane support plate 5525 are connected to form a gantry structure. Alternatively, the first membrane support plate 5523 and the second membrane support plate 5524 may be located below the third membrane support plate 5525.
[0142] The membrane stretching drive mechanism 5521 can be located on the outside of the gantry and connected to the first membrane stretching support plate 5523 and / or the second membrane stretching support plate 5524; the space between the first membrane stretching support plate 5523, the second membrane stretching support plate 5524 and the third membrane stretching support plate 5525 can be a clearance space. During operation, the transfer platform 56 can pass through the gantry between the first membrane stretching support plate 5523 and the second membrane stretching support plate 5524.
[0143] Additionally, the membrane clamping component 551 can be connected to the third membrane support plate 5525, and at least a portion of the membrane clamping component 551 can be located within the clearance space. In this case, the membrane clamping component 551 is located below the third membrane support plate 5525. Furthermore, in the vertical direction, the minimum height of the membrane clamping component 551 is greater than the maximum height of the transfer platform 56, thus preventing the membrane clamping component 551 from colliding with the transfer platform 56.
[0144] In other embodiments, the membrane clamping component 551 may also be connected above the third membrane support plate 5525.
[0145] like Figure 7 As shown, in one embodiment, the transfer platform 56 includes a transfer support frame 561 and a transfer support plate 562. The transfer support frame 561 is connected to the frame 50. The transfer support plate 562 is connected to the transfer support frame 561 and is spaced apart from the frame 50. The transfer support plate 562 is used to place the covering film, and the space between the transfer support plate 562 and the frame 50 is used for the bottom paper to pass through.
[0146] During the separation of the film unit through the cooperation of the pre-peeling module 51, the film stretching assembly 55, and the transfer platform 56, the bottom paper wound by the film material winding module 59 can pass through the space between the transfer support plate 562 and the frame 50 to prevent the bottom paper from accumulating. Moreover, this arrangement also helps to reduce the size of the film taking device 5 in the second direction, which is beneficial to the miniaturization design of the film taking device 5.
[0147] The transfer support frame 561 includes a first transfer support member and a second transfer support member. The first and second transfer support members are spaced apart along a second direction on the transfer support plate 562, and are located on the same side of the transfer support plate 562 in the vertical direction. The first and second transfer support members and the transfer support plate 562 are connected to form a gantry structure. Alternatively, the first and second transfer support members may be located below the transfer support plate 562, and are used to connect the frame 50.
[0148] During operation, the bottom paper can pass under the transfer support plate 562 and is located between the first transfer support and the second transfer support, while also being located above the frame 50.
[0149] In one embodiment, the transfer support plate 562 has vacuum suction holes on its surface facing away from the frame 50, allowing the transfer support plate 562 to adsorb the membrane unit. This makes the cover film more stable on the transfer support plate 562, preventing deformation or misalignment of the cover film.
[0150] Alternatively, vacuum suction holes can be located on the upper surface of the transfer support plate 562 and connected to a corresponding negative pressure device. When the negative pressure device is working, it can generate negative pressure at the vacuum suction holes, thereby adsorbing the covering film.
[0151] like Figure 7 As shown, in one embodiment, the transfer platform 56 further includes a transfer drive assembly 563. The transfer support frame 561 is connected to the frame 50 via the transfer drive assembly 563. The transfer drive assembly 563 is used to drive the transfer support frame 561 to move closer to or further away from the pre-stripping module 51. Specifically, the transfer drive assembly 563 is used to drive the transfer support frame 561 to reciprocate along a first direction.
[0152] When it is necessary to use the pre-peeling module 51 and the film adsorption assembly 521 to separate the cover film from the backing paper, the transfer support frame 561 can be driven away from the pre-peeling module 51 to a suitable position to avoid interference with the movement of the corresponding components (such as the peeling blade 511) in the first direction.
[0153] When the pre-peeling module 51, the film pulling assembly 55, and the transfer platform 56 work together to separate the cover film, the transfer support frame 561 can be driven to move close to the pre-peeling module 51 to a suitable position, such as driving the transfer support frame 561 to move directly below the adsorption module 52, thereby causing the transfer support plate 562 to move directly below the film taking module 52. When the film adsorption assembly 521 moves downward to a suitable position, it can adsorb the cover film on the transfer support plate 562.
[0154] In one embodiment, when the film taking device 5 further includes a film unwinding module 58 and a film rewinding module 59; the unwinding module and the film rewinding module 59 are spaced apart on the frame 50 along a first direction; and in the first direction, a pre-peeling module is located between the film unwinding module 58 and the film rewinding module 59, a transfer platform 56 is located between the pre-peeling module 51 and the film rewinding module 59, and a film pulling assembly 55 is located between the pre-peeling module and the film rewinding module 59.
[0155] First film-coating clamping assembly 53 and second film-coating clamping assembly 54
[0156] like Figure 5 and Figure 6 As shown, in one embodiment, the film taking device 5 further includes a first film-coating clamping component 53 and a second film-coating clamping component 54; the first film-coating clamping component 53 and the second film-coating clamping component 54 are both disposed on the frame 50 and are spaced apart on both sides of the pre-peeling module 51 along the first direction; the first film-coating clamping component 53 and the second film-coating clamping component 54 are both used to clamp or release the film material.
[0157] When the peeling blade 511 needs to be driven to reciprocate in the first reverse direction by the first pre-peeling drive assembly 514, the first film-coating clamping assembly 53 and the second film-coating clamping assembly 54 can simultaneously clamp the film material. This avoids the film material from moving in the first direction during the movement of the peeling blade 511. This not only improves the effect of separating the cover film, but also ensures the cutting accuracy of the subsequent film material.
[0158] In addition, when the pre-peeling platform 515 reciprocates along the first direction, it remains between the first film-coating clamping assembly 53 and the second film-coating clamping assembly 54.
[0159] In the scenario where the film taking device 5 is used in conjunction with the film unwinding module 58 and the film rewinding module 59, in the first direction, both the first coating clamping assembly 53 and the second coating clamping assembly 54 are located between the film unwinding module 58 and the film rewinding module 59. Moreover, the first coating clamping assembly 53 is located between the film unwinding module 58 and the pre-peeling platform 515, and the second coating clamping assembly 54 is located between the film rewinding module 59 and the pre-peeling platform 515.
[0160] When the cutting device 60 needs to cut the cover film on the pre-peeling platform 515, the first film-coating clamping assembly 53 and the second film-coating clamping assembly 54 simultaneously clamp the film material, and the first pre-peeling pressing member 516 and the pre-peeling platform 515 also clamp the film material. When the film material needs to be unwound, the first film-coating clamping assembly 53 and the second film-coating clamping assembly 54 simultaneously release the film material, and the first pre-peeling pressing member 516 and the pre-peeling platform 515 also release the film material. When the pre-peeling module 51 needs to be used to move the unwound film material a predetermined distance along the first direction, the first film-coating clamping assembly 53 and the second film-coating clamping assembly 54 simultaneously release the film material, and the first pre-peeling pressing member 516 and the pre-peeling platform 515 clamp the film material.
[0161] In this scenario, the film material held by the first coating clamping assembly 53 includes the backing paper and the cover film, while the film material held by the second coating clamping assembly 54 only includes the backing paper. This is because the cover film was removed before being unwound to the second coating clamping assembly 54.
[0162] In addition, when the pre-peeling module 51 pre-peeles the cover film (i.e., when the edge of the cover film is rubbed up), the first film-coating clamping component 53 and the second film-coating clamping component 54 simultaneously clamp the film material to lock the film material, prevent wrinkles from forming in the film material during pre-peeling, and facilitate the peeling blade 511 to rub up the edge of the cover film.
[0163] In one embodiment, the first coating clamping assembly 53 includes a coating clamping drive, a first coating clamping plate, and a second coating clamping plate. The coating clamping drive is capable of driving at least one of the first and second coating clamping plates to move, thereby increasing or decreasing the distance between the first and second coating clamping plates. When the distance between the first and second coating clamping plates increases, the film material between them can be released; when the distance between the first and second coating clamping plates decreases, the film material between them can be clamped.
[0164] In one embodiment, the film-coating clamping drive includes a cylinder, a first film-coating clamping plate is connected to the cylinder body, and a second film-coating clamping plate is connected to the piston rod of the cylinder. The cylinder can drive the second film-coating clamping plate to move closer to or further away from the first film-coating clamping plate in order to clamp or release the film material located between the two.
[0165] Additionally, the cylinder can drive the second coating clamping plate to move up and down, bringing it closer to or away from the first coating clamping plate. The first coating clamping plate can be located below the second coating clamping plate, or it can be located above the second coating clamping plate.
[0166] Furthermore, the second film-coating clamping assembly 54 and the first film-coating clamping assembly 53 adopt the same structural configuration. Moreover, the first film-coating clamping assembly 53 and the second film-coating clamping assembly 54 can also adopt other configurations in the prior art that can clamp or release the film material, and this embodiment does not impose too many restrictions here.
[0167] It should be noted that when the film is separated by the pre-peeling module 51, the film pulling assembly 55 and the transfer platform 56, the second film clamping assembly 54 and the first film clamping assembly 53 release the film material during the process of the film pulling assembly 55 pulling the film to the transfer platform 56.
[0168] In the first direction, the second film-coating clamping assembly 54 may be located between the transfer platform and the film winding module 59.
[0169] Edge-starting component 57
[0170] like Figure 1 and Figure 8 As shown, in one embodiment, the film-taking device 5 further includes an edge-lifting assembly 57, which applies force to the cover film to separate it from the backing paper. Additionally, the edge-lifting assembly 57 may be located between the pre-peeling module 51 and the film winding module 59, specifically between the pre-peeling module 51 and the transfer platform 56. During operation, the film is either clamped by the film-pulling assembly 55 or grasped by the film-taking module 52 after passing through the edge-lifting assembly 57.
[0171] In one embodiment, the edge-lifting assembly 57 includes an edge-lifting support frame 571 and an edge-lifting member 572. The edge-lifting support frame 571 is connected to the frame 50, and the edge-lifting member 572 is connected to the edge-lifting support frame 571 for applying force to the cover film passing through it to separate the cover film from the backing paper.
[0172] The edge-lifting component 572 can be located above the edge-lifting support frame 571. The edge-lifting component 572 can be adhesive to adhere the covering film passing through it, thus enabling force to be applied to the covering film. The edge-lifting component 572 can be made of a material with a certain degree of adhesiveness, such as silicone or rubber.
[0173] In addition, the edge-lifting member 572 is a cylindrical structure that can rotate relative to the edge-lifting support frame 571 around its own axis, which reduces the friction between the edge-lifting member 572 and the cover film. Moreover, the axis of the edge-lifting member 572 can be parallel to the second direction.
[0174] In one embodiment, the edge-raising support frame 571 may include two edge-raising support plates, which are spaced apart along the second direction, and the two ends of the edge-raising member 572 are respectively connected to the upper ends of the two edge-raising support plates.
[0175] like Figure 8As shown, in one embodiment, the edge-lifting assembly 57 further includes an edge-lifting drive member 573, which is connected to the edge-lifting support frame 571 and is used to drive the edge-lifting member 572 to move up and down, so that the edge-lifting member 572 moves closer to or away from the pre-peeling module 51.
[0176] In the vertical direction, the edge-lifting component 572 is located above the pre-peeling module 51. The edge-lifting component 572 mainly applies force to the cover film on the peeling blade 511 to separate it from the backing paper. The distance between the edge-lifting component 572 and the pre-peeling module 51 can be adjusted by the edge-lifting drive component 573 to accommodate film materials of different thicknesses.
[0177] In one embodiment, the edge-lifting drive member 573 may be a device capable of driving linear motion of an object, such as a cylinder or an electric cylinder. Alternatively, there may be two edge-lifting drive members 573, each connected to one of two edge-lifting support plates and connected to both ends of the edge-lifting member 572.
[0178] In one embodiment, the edge-raising member 572 is rotatable relative to the edge-raising drive member 573 about its own axis. The axis of the edge-raising member 572 may be parallel to a second direction.
[0179] Film unwinding module 58
[0180] like Figure 1 As shown, in one embodiment, the film unwinding module 58 includes a first film unwinding roller module 581, which is connected to the frame 50 for mounting the film roll and for unwinding the film.
[0181] The first film unwinding roller module 581 includes a first film unwinding drive assembly and a first film unwinding roller. The first film unwinding drive assembly is connected to the frame 50 and is connected to the first film unwinding roller. The first film unwinding roller is used to mount the film roll. The first film unwinding drive assembly is used to drive the first film unwinding roller so that the first film unwinding roller can rotate around its own axis. In this way, the film roll mounted on the first film unwinding roller can be rotated to realize the unwinding of the film roll.
[0182] In addition, the axis of the first unwinding roller can be parallel to the second direction.
[0183] In one embodiment, the first film unwinding drive assembly may be a device capable of driving an object to rotate, comprising components such as a rotary motor and a reducer. The first film unwinding roller may be a device such as an air shaft capable of mounting the film roll. Moreover, the configuration of both the first film unwinding drive assembly and the first film unwinding roller can be existing technology.
[0184] like Figure 1 and Figure 9As shown, in one embodiment, the film unwinding module 58 further includes a film unwinding gravity roller 582, which is movably connected to the frame 50 and can move relative to the frame 50 in the vertical direction to tension the unwound film.
[0185] During operation, the unwound film material can pass under the unwinding gravity roller 582 and be wound around it. The unwinding gravity roller 582 buffers the unwound film material, compensating for the travel difference caused by the mismatch between the pulling speed of the pre-peeling module 51 and the unwinding speed of the first unwinding roller module 581 (as the roll radius decreases, the speed decreases). Specifically, when the unwinding speed of the first unwinding roller module 581 is fast, more film material is unwound. In this case, the unwinding gravity roller 582 can move downwards under its own gravity, thus tensioning the film material. When the unwinding speed of the first unwinding roller module 581 is slow, the length of the buffered film material decreases. In this case, the unwinding gravity roller 582 can move upwards under the support of the film material.
[0186] In one embodiment, the unwinding gravity roller 582 can rotate relative to the frame 50 about its own axis, which can reduce the friction between the unwinding gravity roller 582 and the film.
[0187] like Figure 1 and Figure 9 As shown, in one embodiment, the film unwinding module 58 further includes a gravity roller connecting module 583, and the film unwinding gravity roller 582 is connected to the frame 50 through the gravity roller connecting module 583.
[0188] The gravity roller connecting module 583 includes a gravity roller guide assembly 5831 and a gravity roller connecting assembly 5832. The gravity roller guide assembly 5831 includes a first gravity roller guide portion 5833 and a second gravity roller guide portion 5834. The first gravity roller guide portion 5833 is connected to the frame 50, and the second gravity roller guide portion 5834 cooperates with the first gravity roller guide portion 5833 and can move relative to the first gravity roller guide portion 5833 in the vertical direction. The gravity roller connecting assembly 5832 is connected to the second gravity roller guide portion 5834. The film unwinding gravity roller 582 is connected to the gravity roller connecting assembly 5832 and can rotate relative to the gravity roller connecting assembly 5832 around its own axis. The axis of the film unwinding gravity roller 582 is parallel to the second direction, and the first direction, the second direction, and the vertical direction are perpendicular to each other.
[0189] The first gravity roller guide 5833 can be a guide post, and the second gravity roller guide 5834 can be a slider. The gravity roller connecting assembly 5832 can be a plate-like structure, such as a U-shaped plate, or it can be a block-like structure.
[0190] like Figure 9 As shown, the gravity roller connecting module 583 also includes a gravity roller connecting frame 5835, and the first gravity roller guide part 5833 is connected to the frame 50 through the gravity roller connecting frame 5835. The gravity roller connecting frame 5835 includes a first gravity roller support rod 5836 and a second gravity roller support rod 5837. The first gravity roller support rod 5836 and the second gravity roller support rod 5837 are spaced apart on the frame 50 in the vertical direction. The upper and lower ends of the first gravity roller guide part 5833 are respectively connected to the first gravity roller support rod 5836 and the second gravity roller support rod 5837. The first gravity roller guide part 5833 is spaced apart from the frame 50.
[0191] The second gravity roller guide 5834 may be sleeved on the first gravity roller guide 5833 and located on the first gravity roller support rod 5836 and the second gravity roller support rod 5837.
[0192] In one embodiment, the gravity roller connecting frame 5835 and the frame 50 are arranged along a first direction, and the first gravity roller guide 5833 and the film unwinding gravity roller 582 are both spaced apart from the frame 50 along the first direction. Meanwhile, in the first direction, the first film unwinding roller module 581 is located on the side of the film unwinding gravity roller 582 opposite to the frame 50.
[0193] like Figure 1 and Figure 9 As shown, the film unwinding module 58 further includes a film unwinding clamping module 584, which includes a first film unwinding clamping part 5841, a second film unwinding clamping part 5842, and a film unwinding clamping drive part 5843. The film unwinding from the first film unwinding roller module 581 can pass between the first film unwinding clamping part 5841 and the second film unwinding clamping part 5842 and then be wound around the film unwinding gravity roller 582. The film unwinding clamping drive part 5843 is used to drive at least one of the first film unwinding clamping part 5841 and the second film unwinding clamping part 5842 to move, so that the distance between the first film unwinding clamping part 5841 and the second film unwinding clamping part 5842 can decrease to clamp the film or increase to release the film.
[0194] During the manual pulling of the film material from the unwinding module 58 to the rewinding module 59, the film material can be held by the unwinding clamping module 584 to prevent it from falling to the ground. During subsequent normal operation, the first unwinding clamping part 5841 and the second unwinding clamping part 5842 will release the film material, allowing it to pass smoothly between them.
[0195] In one embodiment, the film unwinding clamping drive unit 5843 can be a cylinder, and both the first film unwinding clamping unit 5841 and the second film unwinding clamping unit 5842 can be plate-shaped structures. Furthermore, the first film unwinding clamping unit 5841 can be connected to the cylinder body, and the second film unwinding clamping unit 5842 can be connected to the piston rod of the cylinder. In this way, the film unwinding clamping drive unit 5843 can drive the second film unwinding clamping unit 5842 to move linearly, causing it to move closer to or away from the first film unwinding clamping unit 5841.
[0196] In addition, the second film unwinding clamping part 5842 may be located above the first film unwinding clamping part 5841.
[0197] Furthermore, the number of film unwinding clamping modules 584 can be set to one or more, and the specific number can be set according to requirements. For example, in Figure 9 In the example shown, there are two film unwinding clamping modules 584.
[0198] In some scenarios, the film material includes a protective film in addition to the cover film and the backing paper. The protective film is placed on the side of the cover film that faces away from the backing paper. After the film material unwinding module 58 unwinds the film material, it is necessary to peel off the protective film first, and then cut and separate the cover film.
[0199] In one embodiment, the film unwinding module 58 further includes a second film unwinding roller module 585; the first film unwinding roller module 581 and the second film unwinding roller module 585 are spaced apart on the frame 50; the second film unwinding roller module 585 is used to wind up the protective film of the film to remove the protective film on the film; the cutting device 60 is used to cut the film after the protective film has been removed.
[0200] The second film unwinding roller module 585 and the first film unwinding roller module 581 are configured in the same way. During operation, the protective film can be manually wound around the second film unwinding roller module 585. After the first film unwinding roller module 581 unwinds the film, the second film unwinding roller module 585 can then rewind the protective film.
[0201] In one embodiment, the first film unwinding roller module 581 is located below the second film unwinding roller module 585; and / or, the axis of the first film unwinding roller module 581 is parallel to the second direction, and the axis of the second film unwinding roller module 585 is parallel to the second direction, wherein the axis of the first film unwinding roller module 581 is the axis of the first film unwinding roller.
[0202] In one embodiment, the film material winding module 59 and the film material unwinding module 58 are configured in the same way.
[0203] This utility model embodiment also provides a film applicator, which includes the film dispensing device 5 described in any of the above embodiments.
[0204] In addition, the film applicator also includes a material storage device for placing the target object; the cover film separated by the film taking device 5 can be applied to the target object on the material storage device.
[0205] Furthermore, the laminating machine also has a corresponding driving device, which can drive the laminating adsorption assembly 521 to reciprocate along the second direction, allowing the laminating adsorption assembly 521 to move above the material storage device. Then, in conjunction with the laminating drive assembly 522, the covering film can be adhered to the target object. The laminating drive assembly 522 can be mounted on the driving device, and during operation, the driving device can drive the laminating adsorption assembly 521 and the laminating drive assembly 522 to move synchronously along the second direction.
[0206] In one embodiment, the material storage device can be a support platform on which the target object, such as an FPC, can be placed on the upper surface.
[0207] In addition, the film applicator also has a corresponding control device to control the operation of each component in the film dispensing device 5. The control device can be a PLC or a microcontroller, etc.
[0208] 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.
