Description

Technical Field

[0001] This utility model relates to the field of FPC manufacturing technology, and in particular to an automatic laminating machine. Background Technology

[0002] In the FPC manufacturing process, copper foil needs to be coated (usually with a PI film). The film typically exists in either roll or sheet form. For sheet films, they can be pre-processed to correspond to the shape of the copper foil, thereby improving overall processing efficiency. However, currently, the application of sheet films to copper foil is still done manually. Manual coating requires a certain level of skill, and the quality of manual coating is difficult to guarantee consistently, and it is also time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide an automatic laminating machine that can automatically laminate, thereby improving laminating efficiency and ensuring laminating quality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic laminating machine includes a controller, a machine base, and a film feeding device, a copper foil feeding device, a heating and pressing device, and a release paper pulling device mounted on the machine base. The film feeding device, the copper foil feeding device, the heating and pressing device, and the release paper pulling device are all connected to the controller. The machine platform is equipped with a film feeding area, a copper foil feeding area, a first working area, a second working area, and a third working area; The film feeding device includes a first moving mechanism and a film adsorption platform for placing and adsorbing film. The first moving mechanism drives the film adsorption platform to move back and forth between the film feeding area and the first working area. The copper foil feeding device includes a second moving mechanism and a copper foil adsorption platform for placing and adsorbing copper foil. The second moving mechanism drives the copper foil adsorption platform to move back and forth between the copper foil feeding area and the second working area. The heating and pressing device includes a third moving mechanism and a heating adsorption platform. The third moving mechanism drives the heating adsorption platform to move between the first working area, the second working area and the third working area. The adsorption surface of the heating adsorption platform is arranged downward. The paper-pulling device is located in the third working area; The heating and pressing device works in conjunction with the copper foil adsorption platform to transfer the copper foil from the copper foil adsorption platform to the heating and adsorption platform; the heating and pressing device works in conjunction with the film adsorption platform to heat-press the film onto the copper foil on the heating and adsorption platform; the heating and pressing device works in conjunction with the release paper removal device to remove the release paper from the film.

[0005] After the above setup, the film (with release paper) is positioned and fixed on the film adsorption platform in the film feeding area, and the copper foil is positioned and fixed on the copper foil adsorption platform in the copper foil feeding area. The film and copper foil will not shift during movement, ensuring proper alignment and facilitating rapid movement. The heating and pressing device first adsorbs and grips the film in the first working area, then moves to the third working area to cooperate with the release paper removal device to remove the release paper from the film. Afterwards, the heating and pressing device moves to the second working area and presses down onto the copper foil adsorption platform, heating it to thermally press the film onto the copper foil. Once the heating and pressing device releases the film, one coating operation is complete. This invention automatically completes the coating operation after positioning and feeding, ensuring reliable coating quality and high efficiency.

[0006] Preferably, the thin film adsorption stage, copper foil adsorption stage, and heating adsorption stage all include a carrier plate and an adsorption plate. The adsorption plate is provided with a plurality of vacuum adsorption holes, which are connected to an external vacuum pump. The carrier plate or adsorption plate of the heating adsorption stage is provided with a plurality of heating holes, and heating elements are installed in the heating holes. The thin film adsorption stage, copper foil adsorption stage, and heating adsorption stage configured in this way have simple structures and are easy to manufacture.

[0007] Preferably, both the first and second moving mechanisms are linear motion modules; The third moving mechanism includes a first horizontal moving module, a first lifting moving module, a rotating module, and a first buffer assembly. The first horizontal moving module drives the first lifting moving module to move between the first working area, the second working area, and the third working area. The first lifting moving module drives the rotating module to move up and down. The rotating module drives the first buffer assembly to rotate horizontally. The first buffer assembly includes a fixed plate, a buffer plate, several first equal-height screws, and several first springs. The fixed plate is connected to the rotating module, and the buffer plate is positioned below the fixed plate. The first equal-height screws pass through the fixed plate and connect to the buffer plate. The buffer plate is movable relative to the fixed plate. One end of each first spring is connected to the fixed plate, and the other end is connected to the buffer plate. The heating adsorption stage is locked below the buffer plate. This configuration results in a simple structure and easy control for the first, second, and third moving mechanisms. Furthermore, the first buffer assembly ensures uniform stress during hot pressing of the film and copper foil and avoids rigid collisions.

[0008] Preferably, the release liner removal device includes a plurality of first suction cups, the suction ports of the first suction cups facing upwards and on the same horizontal plane, and the first suction cups are connected to an external vacuum device. The release liner is removed by vacuum suction of the first suction cups in conjunction with the movement of a third moving mechanism, making the operation simple and efficient.

[0009] Preferably, it further includes a first dust removal component for removing dust from the film and a second dust removal component for removing dust from the copper foil, wherein the first dust removal component is disposed between the film feeding area and the first working area, and the second dust removal component is disposed between the copper foil feeding area and the second working area; The first dust removal component is an air curtain machine, which is connected to a controller; The second dust removal assembly includes a rubber roller and two second buffer assemblies, each corresponding to one end of the rubber roller. Each second buffer assembly includes a mounting base, at least two buffer screws, and a second spring corresponding to each buffer screw. The buffer screws pass through the second springs and the mounting base sequentially and are connected to the machine base. The mounting base can slide along the length of the buffer screws, which is vertical. The end of the rubber roller is rotatably connected to the mounting base. By setting up the first and second dust removal assemblies, impurities on the surfaces of the film and copper foil can be removed, preventing air bubbles from forming after lamination and ensuring coating quality.

[0010] Preferably, the system further includes a first visual inspection element for correction and a second visual inspection element for correction and finished product inspection. The first visual inspection element is positioned between the first and second working areas, and the second visual inspection element is positioned between the copper foil feeding area and the second working area. The first and second visual inspection elements are connected to a controller. The first visual inspection element photographs the film after it is adsorbed and grasped by the heating and pressing device. The second visual inspection element photographs the polarity of the copper foil on the copper foil adsorption platform. The controller compares the deviation between the current position of the film and the set position, and compares the deviation between the current position of the copper foil and the set position, thereby controlling the third moving mechanism to correct and adjust the position of the film, ensuring accurate alignment between the copper foil and the film and guaranteeing the coating quality. After coating is completed, the second visual inspection element photographs the coating quality to check and reject unqualified products.

[0011] Preferably, it also includes a film feeding device and a copper foil feeding device, both of which are connected to a controller; The film feeding device is located in the film feeding area and includes a film stacking mechanism for stacking films and a film moving mechanism for grabbing the film on the film stacking mechanism and moving it to the film adsorption platform. The copper foil feeding device is located in the copper foil feeding area. It includes a copper foil stacking mechanism for stacking copper foil and a copper foil moving mechanism for grabbing the copper foil on the stacking mechanism and moving it to the copper foil adsorption platform. With this configuration, the machine can automatically grab the film and copper foil to achieve automatic feeding. Operators only need to replenish the material periodically, resulting in a higher degree of automation.

[0012] Preferably, it also includes an unloading device, which includes an unloading moving mechanism, a barrier plate stacking mechanism, and a barrier plate moving mechanism, all of which are connected to a controller; The machine is located near the copper foil feeding area, and a finished product area is also provided. The heating and pressing device, copper foil feeding device, and unloading and moving mechanism work together to transfer the coated copper foil to the finished product area. The isolation plate stacking mechanism is used to stack isolation plates, and the isolation plate moving mechanism is used to grab the isolation plates from the isolation plate stacking mechanism and move them to the finished product area. With this configuration, the coated copper foil can be automatically unloaded. At the same time, each time a finished product (i.e., the coated copper foil) is unloaded into the finished product area, an isolation plate is placed in the finished product area, so that the finished products do not come into direct contact with each other and avoid adjacent finished products sticking together due to residual heat.

[0013] Preferably, the film stacking mechanism, copper foil stacking mechanism, and separator plate stacking mechanism each include a stacking frame, a screw, a stacking generator, several guide posts, and several limiting posts. The upper end of each guide post is locked to the machine base, and the lower end of each guide post is connected to a mounting plate. The stacking generator is mounted on the mounting plate. The screw is parallel to the guide posts and is threadedly connected to the stacking frame. The stacking generator drives the screw to rotate. The limiting posts are locked to the machine base and are slidably engaged with the stacking frame. The limiting posts corresponding to the film stacking mechanism form a limiting frame adapted to the shape of the film, the limiting posts corresponding to the copper foil stacking mechanism form a limiting frame adapted to the shape of the copper foil, and the limiting posts corresponding to the separator plate stacking mechanism form a limiting frame adapted to the shape of the separator plate. The film moving mechanism, copper foil moving mechanism, unloading moving mechanism, and separator plate moving mechanism each include a second horizontal moving module, a second lifting moving module, and several second suction cups. The second horizontal moving module drives the second lifting moving module to move horizontally, and the second lifting moving module drives the second suction cups to move up and down synchronously. The suction ports of the second suction cups are arranged downwards, and the suction ports of the second suction cups are on the same horizontal plane. The second suction cups are connected to an external vacuum pump. This configuration of the film stacking mechanism, copper foil stacking mechanism, and separator plate stacking mechanism allows for upward material pushing, simplifying the control of the corresponding second lifting moving modules.

[0014] Preferably, a release paper storage cavity is provided on the machine near the release paper pulling device. This arrangement facilitates the storage and management of the pulled-out release paper, preventing it from interfering with subsequent release paper pulling operations.

[0015] This utility model has the following beneficial effects: 1. After the positioning and feeding are completed, this utility model can automatically complete the film coating operation, with reliable film coating quality and high efficiency. 2. Adding visual inspection can improve the quality of film coating.

[0016] 3. By adding automatic feeding and automatic unloading, the entire film coating process can be automated. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-14 As shown, this utility model discloses an automatic laminating machine, which includes a controller, a machine base 10, and a film feeding device, a copper foil feeding device, a film feeding device, a copper foil feeding device, a heating and pressing device 50, a release paper pulling device 60, a unloading device, a first dust removal assembly 41, a second dust removal assembly 46, a first vision inspection element 47, and a second vision inspection element 48, all mounted on the machine base 10. The controller can be a PLC, and the first vision inspection element 47 and the second vision inspection element 48 can be industrial cameras.

[0034] The machine 10 is provided with a film feeding area 11, a copper foil feeding area 12, a first working area 13, a second working area 14, a third working area 15, and a finished product area 16. In this case, the first working area 13, the second working area 14, and the third working area 15 are arranged sequentially in a straight line, and the finished product area 16 is located close to the copper foil feeding area 12.

[0035] The film feeding device is located in the film feeding area 11 and includes a film stacking mechanism 21 and a film moving mechanism 22. The film stacking mechanism 21 is used to stack films (with release paper). Specifically, the film stacking mechanism 21 includes a stacking frame 211, a screw 212, a stacking and discharging machine 213, several guide posts 214, and several limiting posts 215. The guide posts 214, screw 212, and stacking and discharging machine 213 are placed under the table surface 17 of the machine base 10. The upper end of the guide post 214 is locked to the machine base 10, and the lower end of the guide post 214 is fixedly connected to a mounting plate 216. The stacking and discharging machine 213 is mounted on the mounting plate 216. The screw 212 is parallel to the guide post 214 and is rotatably connected to the mounting plate 216. The stacking frame 211 is threadedly connected to the screw 212, and is also slidably connected to the guide post 214. The film stacking mechanism 213 drives the screw 212 to rotate, thereby allowing the stacking rack 211 to rise and fall. The film stacking mechanism 213 is connected to a controller. Limiting posts 215 are locked onto the table surface 17 of the machine base 10, and the limiting posts 215 slide against the stacking rack 211. The limiting posts 215 corresponding to the film stacking mechanism 21 form a limiting frame that matches the shape of the film, ensuring that the film can be stacked in a uniform posture and will not move arbitrarily. After each film grab, the film stacking mechanism 213 drives the stacking rack 211 to rise, ensuring that the topmost film is always at the same height, facilitating film grabbing.

[0036] The film moving mechanism 22 is used to pick up the film from the film stacking mechanism 21 and move it to the film adsorption platform 32 located in the film loading area 11. Specifically, the film moving mechanism 22 includes a second horizontal moving module 221, a second lifting moving module 222, and several second suction cups 223. The second horizontal moving module 221, the second lifting moving module 222, and the second suction cups 223 are all connected to a controller. The second horizontal moving module 221 drives the second lifting moving module 222 to move horizontally, and the second lifting moving module 222 drives the second suction cups 223 to move up and down synchronously. The adsorption ports of the second suction cups 223 are set downwards, and the adsorption ports of the second suction cups 223 are on the same horizontal plane. The second suction cups 223 are connected to an external vacuum pump. In this case, the second horizontal moving module 221 and the second lifting moving module 222 are both linear moving modules based on motors, which is the prior art. They generally include a motor, a guide rail, a threaded rod and a slider. The guide rail and the threaded rod are parallel to each other, the slider is slidably connected to the guide rail, and the slider is also threadedly connected to the threaded rod. The motor drives the threaded rod to rotate, so that the slider can move along the length of the guide rail.

[0037] The film feeding device includes a first moving mechanism 31 and a film adsorption platform 32 for placing and adsorbing the film. The first moving mechanism 31 drives the film adsorption platform 32 to move back and forth between the film feeding area 11 and the first working area 13. The first moving mechanism 31 is a linear motion module based on a motor, which will not be described in detail. The first moving mechanism 31 is connected to a controller. The film adsorption platform 32 includes a carrier plate 33 and an adsorption plate 34. Several vacuum adsorption holes (not shown in the figure) are arranged on the adsorption plate 34. The vacuum adsorption holes are connected to an external vacuum pumping device, which is controlled by the controller. Alternatively, a three-way valve is installed on the pipe connecting the vacuum adsorption holes to the external vacuum pumping device (for example, the common end of the three-way valve is connected to the vacuum adsorption hole, the normally closed end of the three-way valve is connected to the external vacuum pumping device, and the normally open end of the three-way valve is suspended (i.e., connected to the atmosphere)). This three-way valve is connected to the controller.

[0038] The first dust removal component 41 is disposed between the film feeding area 11 and the first working area 13. It is used to remove dust from the film. In this case, the first dust removal component 41 is an air curtain machine, which is connected to a controller. When the film adsorption platform 32 moves the film from the film feeding area 11 to the first working area 13, and the film adsorption platform 32 passes the first dust removal component 41, the first dust removal component 41 is activated to blow air onto the film and remove dust.

[0039] The copper foil feeding device is located in the copper foil feeding area 12 and includes a copper foil stacking mechanism 42 for stacking copper foil and a copper foil moving mechanism 43 for gripping the copper foil on the copper foil stacking mechanism 42 and moving it to the copper foil adsorption platform 45 (when located in the second working area 14). The copper foil stacking mechanism 42 and the copper foil moving mechanism 43 are connected to a controller. The structure of the copper foil stacking mechanism 42 is similar to that of the film stacking mechanism 21, except that the limiting posts 215 of the copper foil stacking mechanism 42 form a limiting frame that matches the shape of the copper foil, which will not be described in detail. The structure of the copper foil moving mechanism 43 is similar to that of the film moving mechanism 22, except that the number of second suction cups 223 corresponding to the copper foil moving mechanism 43 is increased to ensure reliable gripping of copper foil, which will not be described in detail.

[0040] The copper foil feeding device includes a second moving mechanism 44 and a copper foil adsorption platform 45 for placing and adsorbing copper foil. The second moving mechanism 44 drives the copper foil adsorption platform 45 to move back and forth between the copper foil feeding area 12 and the second working area 14. The second moving mechanism 44 is a motor-based linear motion module, which will not be described in detail. The second moving mechanism 44 is connected to a controller. The structure of the copper foil adsorption platform 45 is the same as that of the thin film adsorption platform 32, and will not be described in detail.

[0041] The second dust removal assembly 46 is disposed between the copper foil feeding area 12 and the second working area 14, and is used to remove dust from the copper foil. In this embodiment, the second dust removal assembly 46 includes a rubber roller 461 and two second buffer assemblies, with each of the two second buffer assemblies corresponding to one end of the rubber roller 461. Each second buffer assembly includes a mounting base 462, at least two buffer screws 463, and a second spring 464 corresponding to each buffer screw 463. The buffer screws 463 pass through the second springs 464 and the mounting base 462 in sequence and are connected to the gantry frame 18 on the machine base 10. The mounting base 462 can slide along the length of the buffer screws 463, which is vertical. The end of the rubber roller 461 is rotatably connected to the mounting base 462. When the copper foil adsorption platform 45 moves towards the second working area 14, the copper foil loaded on it is rolled by the rubber roller 461, thereby achieving dust removal.

[0042] The second visual inspection element 48 is also located between the copper foil loading area 12 and the second working area 14. It is mounted on the gantry 18 of the machine tool 10. The second visual inspection element 48 is used for correction and finished product inspection, and it is connected to the controller. When the copper foil adsorption platform 45 moves towards the second working area 14, the second visual inspection element 48 takes a picture of the copper foil loaded on the copper foil adsorption platform 45 as it passes under the second visual inspection element 48 to compare its position with the set position. This provides an adjustment reference for the subsequent adjustment of the position of the film gripped by the heating and pressing device 50, thus achieving correction.

[0043] The heating and pressing device 50 is mounted on the gantry 18 of the machine base 10. It includes a third moving mechanism 51 and a heating and adsorption table 52. The third moving mechanism 51 includes a first horizontal moving module 53, a first lifting moving module 54, a rotating module, and a first buffer assembly. The first horizontal moving module 53, the first lifting moving module 54, and the rotating module are all connected to a controller. The first horizontal moving module 53 drives the first lifting moving module 54 to move between the first working area 13, the second working area 14, and the third working area 15. The first lifting moving module 54 drives the rotating module to move up and down. The rotating module drives the first buffer assembly to rotate horizontally. The first horizontal moving module 53 and the first lifting moving module 54 are both linear moving modules based on motors, and will not be described in detail. The rotating module includes a rotary motor 551, a fixed base 552, and a turntable 553. The fixed base 552 is connected to the first lifting moving module 54, and the turntable 553 is rotatably connected to the fixed base 552. The rotary motor 551 is drively connected to the turntable 553.

[0044] The first buffer assembly includes a fixed plate 561, a buffer plate 562, several first equal-height screws 563, and several first springs 564. The fixed plate 561 is bolted to the turntable 553 of the rotating module. The buffer plate 562 is located below the fixed plate 561. The first equal-height screws 563 pass through the fixed plate 561 and connect to the buffer plate 562, allowing the buffer plate 562 to move relative to the fixed plate 561. One end of each first spring 564 is connected to the fixed plate 561, and the other end is connected to the buffer plate 562. The heating adsorption stage 52 is locked below the buffer plate 562. The adsorption surface of the heating adsorption stage 52 faces downward. The structure of the heating adsorption stage 52 is similar to that of the thin-film adsorption platform 32, except that several heating elements 521 are added to the heating adsorption stage 52. Several heating holes are provided on the platform 33 or adsorption plate 34 of the heating adsorption stage 52, and the heating elements 521 are installed in the heating holes. The heating elements 521 can be electric heating rods, which are connected to a controller.

[0045] The first visual detection element 47 is disposed between the first working area 13 and the second working area 14, and is used for correction. The first visual detection element 47 is connected to the controller.

[0046] The release paper tearing device 60 is located in the third working area 15. Specifically, the release paper tearing device 60 includes several first suction cups 61, with the suction ports of the first suction cups 61 facing upwards and on the same horizontal plane. The first suction cups 61 are connected to an external vacuum device. The first suction cups 61 are connected to a controller. A release paper collection cavity 19 is provided on the machine base 10 near the release paper tearing device 60. When the release paper is torn from the film and the first suction cups 61 release the release paper, the release paper naturally falls into the release paper collection cavity 19 to collect and manage the torn release paper.

[0047] The unloading device is located near the finished product area 16. The unloading device includes an unloading moving mechanism 71, a partition plate stacking mechanism 72, and a partition plate moving mechanism 73, all of which are connected to a controller. The unloading moving mechanism 71 is mounted on the gantry 18. It grabs the finished products moving to the copper foil loading area 12 and moves them to the finished product area 16 for stacking. The partition plate stacking mechanism 72 is used to stack partition plates, and the partition plate moving mechanism 73 is used to grab the partition plates from the partition plate stacking mechanism 72 and move them to the finished product area 16. The structures of the unloading moving mechanism 71 and the partition plate moving mechanism 73 are similar to those of the copper foil moving mechanism 43, and the structure of the partition plate stacking mechanism 72 is similar to that of the copper foil stacking mechanism 42, and will not be described again. The limiting posts 215 corresponding to the partition plate stacking mechanism 72 form a limiting frame that matches the shape of the partition plate.

[0048] The working principle of this utility model can be summarized as follows: 1. Place a set number of films, copper foils and separators on the film stacking mechanism 21, the copper foil stacking mechanism 42 and the separator plate stacking mechanism 72 respectively.

[0049] 2. The film moving mechanism 22 picks up the uppermost film in the film stacking mechanism 21 and moves it onto the film adsorption platform 32. After the film adsorption platform 32 stabilizes the film, it is cleaned and moved to the first working area 13.

[0050] 3. The copper foil moving mechanism 43 picks up the top copper foil from the copper foil stacking mechanism 42 and moves it onto the copper foil adsorption platform 45. After the copper foil is stabilized by the copper foil adsorption platform 45, it is cleaned and photographed, and then moved to the second working area 14.

[0051] 4. The heating and pressing device 50 first adsorbs and grasps the film located in the first working area 13 (the heating and pressing device 50 first adsorbs the film, and then the film adsorption platform 32 releases the film). After taking a picture, it is moved to the third working area 15. After the first suction cup 61 adsorbs the release paper at the bottom of the film, the heating and adsorption platform 52 is raised slightly and moved horizontally to remove the release paper. Alternatively, the order of removing the release paper and taking pictures can be interchanged.

[0052] 5. The heating and pressing device 50 moves the film after the release paper has been removed to the second working area 14. After the film and copper foil are accurately aligned (the controller compares the two photos taken to obtain the positional deviation data of the film and copper foil, and then controls the third moving mechanism 51 to correct and adjust the position of the film to ensure that the copper foil can be accurately aligned with the film), the film moves down and sticks to the copper foil. The heating adsorption stage 52 and the copper foil adsorption stage 45 cooperate to press the two together. At the same time, the heating adsorption stage 52 turns on the heating, so that the film is hot-pressed onto the copper foil.

[0053] 6. After the heating and pressing device 50 leaves, the copper foil adsorption platform 45 moves towards the copper foil loading area 12. When it passes the second visual inspection element 48, it takes another picture for finished product inspection. For finished products that pass the inspection, they are moved to the finished product area 16 by the unloading and moving mechanism 71.

[0054] 7. The isolation plate moving mechanism 73 moves an isolation plate from the isolation plate stacking mechanism 72 to the finished product area 16 to isolate the finished products.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
