[0030] like Figures 1 to 7 As shown, an embodiment of the present invention provides a film laminating machine, which is used to coat copper foil film materials on circuit boards. The film laminating machine includes a frame 10, a first feeding mechanism 20, a feeding and conveying mechanism 30, a second feeding mechanism 40, a film laminating mechanism 50 and a feeding mechanism 60, and several modules are the core components of the film laminating machine. Among them, the first feeding mechanism 20 includes a sheet film material storage seat 21 and a first feeding structure 22, the feeding and conveying mechanism 30 includes a placement seat 31, a transmission guide rail 32 and a driving structure 33, the second feeding mechanism 40 includes a circuit board storage seat 41, an intermediate platform 42 and a second feeding structure 43, and the feeding mechanism 60 includes a feeding seat 61 and a feeding structure 62. The sheet film material storage seat 21 and the first feeding structure 22 are both installed on the frame 10, and the sheet copper foil film material is placed on the sheet film material storage seat 21. The film laminating process is carried out by conveying the sheet copper foil film material through the first feeding structure 22. The transmission rail 32 and the driving structure 33 are both installed on the frame 10, the placement seat 31 is slidably connected to the transmission rail 32, and the first feeding structure 22 conveys the copper foil film material on the sheet film material storage seat 21 to the placement seat 31. In the film laminating machine, the driving structure 33 is drivingly connected to the placement seat 31, and the placement seat 31 has a first station and a second station on the transmission rail 32. The placement seat 31 waits at the first station for the first feeding structure 22 to convey the copper foil film material from the sheet film material storage seat 21. The film material (i.e., the copper foil film material) on the placement seat 31 is transferred from the first station to the second station along the transmission rail 32 under the drive of the driving structure 33. In the film laminating machine, the circuit board storage seat 41, the intermediate platform 42, and the second feeding structure 43 are all installed on the frame 10, and the second feeding structure 43 transfers the circuit board stored in the circuit board storage seat 41 to the intermediate platform 42 to wait for the film laminating operation. The film pasting mechanism 50 is assembled on the frame 10, and the film pasting mechanism 50 is located between the second station and the middle platform 42. The film pasting mechanism 50 takes the film material on the placement seat 31 at the second station and transfers it to the middle platform 42 to paste the film with the circuit board to obtain the product. After the film pasting is completed, the film pasting mechanism 50 takes the product from the middle platform 42 and transfers it to the placement seat 31 at the second station, and then performs the unloading operation. The unloading seat 61 and the unloading structure 62 are both installed on the frame 10. The unloading structure 62 takes the product on the placement seat 31 at the second station and transfers it to the unloading seat 61 for storage.

[0031] The laminating machine of the present invention is used to laminate copper foil materials on circuit boards. All processing operations, from loading sheet copper foil materials, loading circuit boards, laminating copper foil materials and unloading, are performed through the corresponding core component modules of the laminating machine, namely the first loading mechanism 20, the loading and conveying mechanism 30, the second loading mechanism 40, the laminating mechanism 50 and the unloading mechanism 60. During the whole laminating process, no manpower is required for auxiliary processing and production, thereby realizing fully automated processing and production, saving labor costs, and greatly improving processing and production efficiency.

[0032] like Figure 1 and Figure 5 As shown, the film laminating machine of the present invention also includes a CCD detection device 70 and a control device 80. The CCD detection device 70 is installed on the frame 10. The CCD detection device 70 is located between the second station and the intermediate platform 42. During the film laminating operation of the film laminating mechanism 50, the film laminating mechanism 50 removes the copper foil film material from the placement seat 31 of the second station and transfers it to the intermediate platform 42. The film laminating mechanism 50 carries the copper foil film material through the CCD detection device 70, and the CCD detection device 70 detects whether the relative position of the film material on the film laminating mechanism 50 is correct. If the relative position is incorrect, a corresponding position adjustment is required (if the relative position is correct, no adjustment is required). Then, the film laminating mechanism 50 continues to transfer the film material to the intermediate platform 42 with the film material, and covers the film material on the circuit board located on the intermediate platform 42 to complete the film laminating operation. Furthermore, the first loading structure 22, the loading conveying mechanism 30, the second loading structure 43, the film pasting mechanism 50, the unloading structure 62 and the CCD detection device 70 are respectively electrically connected to the control device 80, that is, the film pasting machine of the present invention issues corresponding working instructions to each part through the control device 80, thereby coordinating the entire film pasting process. In the present invention, the control device 80 can be used but not limited to the MCU processing module, PCL processing module, etc. that have been maturely applied in the prior art, and can also be other devices that can realize the control function, such as a microcomputer.

The first moving device 51, the horizontal adjustment device 52 and the film attaching adsorption plate 53 are all electrically connected to the control device 80. After the placement seat 31 transports the copper foil film material from the first station to the second station, the control device 80 controls the first moving device 51 to move above the second station, and then the film attaching adsorption plate 53 is driven by the first moving device 51 to descend until it contacts the copper foil film material, and then the film attaching adsorption plate 53 vacuums and adsorbs the copper foil film material, and then the film attaching adsorption plate 53 rises, and then the copper foil film material is transferred to the middle platform 42, and finally the film attaching adsorption plate 53 descends again to attach the copper foil film material to the circuit board, completing the film attaching operation to obtain the product. After the film sticking operation is completed, the film sticking adsorption plate 53 continues to adsorb the product parts, and is driven by the first moving device 51 to return to the second station, and then the product parts are placed on the placement seat 31. Then, the unloading structure 62 transfers the product parts placed on the placement seat 31 of the second station to the unloading seat 61 for storage. Then, the control device controls the driving structure 33 to drive the placement seat 31 from the second station back to the first station, thereby cyclically performing the loading and film sticking processing operations.

[0034] like Figure 6 As shown, in the present invention, the first loading structure 22 includes a second moving device 221 and a first loading suction cup assembly 222, the second moving device 221 is installed on the frame 10, the first loading suction cup assembly 222 is connected to the second moving device 221, and the second moving device 221 and the first loading suction cup assembly 222 are both electrically connected to the control device 80. The first loading suction cup assembly 222 is used to absorb the copper foil film material on the sheet film material storage seat 21, and then transferred to the placement seat 31 at the first station.

[0035] like Figure 3 As shown, the second loading structure 43 includes a third moving device 431 and a second loading suction cup assembly 432. Similarly, the circuit board placed on the circuit board storage seat 41 is also transferred by adsorption. The third moving device 431 is installed on the frame 10, and the second loading suction cup assembly 432 is connected to the third moving device 431. The third moving device 431 and the second loading suction cup assembly 432 are both electrically connected to the control device 80.

[0036] The copper foil film material and the circuit board are transferred after adsorption by adsorption, which can protect the surface of the copper foil film material and the circuit board from being scratched and ensure product quality.

[0037] Furthermore, the driving structure 33 includes a driving motor 331 and a screw-nut pair 332. The driving motor 331 is installed on the frame 10. The screw of the screw-nut pair 332 is connected to the power shaft of the driving motor 331. The nut of the screw-nut pair 332 is connected to the placement seat 31. The driving motor 331 is electrically connected to the control device 80.

[0038] like Figure 3 As shown, the laminating machine further includes an intermediate conveying rail 421, an intermediate driving device and a paper tearing device 90. The surface of the copper foil film material used is covered with a layer of protective paper. After the copper foil film material is pasted on the circuit board, this layer of protective paper needs to be torn off. In the laminating machine of the present invention, the paper tearing device 90 is used to perform the paper tearing operation. Specifically, the intermediate conveying rail 421 and the intermediate driving device are both installed on the frame 10, the intermediate platform 42 is slidably connected to the intermediate conveying rail 421, the intermediate driving device is drivingly connected to the intermediate platform 42, and the intermediate platform 42 has a film laminating station and a paper tearing station on the intermediate conveying rail 421. The film laminating operation is performed at the film laminating station, and the paper tearing operation is performed at the paper tearing station. The intermediate driving device drives the intermediate platform 42 to move between the film pasting station and the paper tearing station. The film pasting station, the CCD detection device 70 and the second station are arranged in a straight line. The intermediate driving device is electrically connected to the control device 80. The paper tearing device 90 is installed on the frame 10. The paper tearing device 90 is electrically connected to the control device 80. After the film adsorption plate 53 has pasted the copper foil film material on the circuit board, the control device 80 first controls the film adsorption plate 53 to stop adsorption. The control device 80 simultaneously controls the intermediate platform 42 to adsorb the circuit board. Then the control device 80 controls the intermediate driving device to drive the intermediate platform 42 to transfer from the film pasting station to the paper tearing station along the intermediate conveying rail 421. Then the control device 80 controls the paper tearing device 90 to tear off the film material protection paper of the product piece located at the paper tearing station.

[0039] In this embodiment, the intermediate platform 42 includes an upper platform 424 and a lower platform 425, and the intermediate transfer rail 421 includes a first guide rail group 4211 and a second guide rail group 4212, the first guide rail group 4211 is parallel to the second guide rail group 4212, the two guide rails of the second guide rail group 4212 are located between the two guide rails of the first guide rail group 4211, the upper platform 424 is slidably connected to the first guide rail group 4211, and the lower platform 425 is slidably connected to the second guide rail group 4212, and during the sliding process, the upper platform 424 and the lower platform 425 do not interfere with each other. The upper platform 424 and the lower platform 425 arranged up and down are used to alternately perform the transfer operation, which can greatly improve the efficiency of film pasting and paper tearing operations, and the up and down arrangement form better and more fully utilizes the assembly space. Correspondingly, the intermediate driving device includes a first intermediate driving device and a second intermediate driving device. The first intermediate driving device is drivingly connected to the upper platform 424 , and the second intermediate driving device is drivingly connected to the lower platform 425 . Both the first intermediate driving device and the second intermediate driving device are electrically connected to the control device 80 .

[0040] Furthermore, a slider is provided on the second guide rail group 4212 of the present embodiment, and the lower platform 425 is connected to the slider in a lifting and sliding manner; the slider is connected to the second intermediate driver. Since the lower platform 425 is arranged in a passing manner through the upper platform 424, that is, the table top of the lower platform 425 is lower than the table top of the upper platform 424, in order to enable the table top of the lower platform 425 to be located at the same height as the table top of the upper platform 424 at both the film pasting station and the paper tearing station, the film pasting machine further includes an auxiliary lifting cylinder, the auxiliary lifting cylinder is connected to the slider, the piston rod end of the lifting cylinder is connected to the lower platform 425, and the lifting cylinder is electrically connected to the control device 80. When the lower platform 425 adsorbs the circuit board and is located at the film pasting station or the paper tearing station, the control device 80 will control the auxiliary lifting cylinder to drive the lower platform 425 to rise to the same height as the table top of the upper platform 424. After the film pasting operation or the paper tearing operation is completed, the control device 80 controls the auxiliary lifting cylinder to drive the lower platform 425 to descend.

[0041] like Figure 2 and Figure 6As shown, in the film laminating machine of the present invention, the paper tearing device 90 includes a lifting and lowering pressure plate assembly 91, an angle-lifting assembly 92 and a paper tearing clamp assembly 93. Specifically, the lifting and lowering pressure plate assembly 91 includes a cylinder 911 and a pressure plate 912, the angle-lifting assembly 92 includes an angle-lifting cylinder 921 and an angle-lifting roller 922, and the paper tearing clamp assembly 93 includes a paper tearing moving part 931 and a paper tearing clamp 932.

After the film laminating operation is completed, the intermediate platform 42 transfers the product from the film laminating station to the paper tearing station. At this time, the cylinder 911 drives the pressing plate 912 to descend and press the product, and the angle roller 922 is pressed against the protective paper. Then the angle cylinder 921 is extended and retracted, and the angle roller 922 rolls and rubs on the protective paper. After the angle cylinder 921 is extended and retracted, the cylinder 911 drives the pressing plate 912 to rise, and the protective paper and the copper foil are separated. At the same time, electrostatic separation is generated between the two, causing a corner of the protective paper to tilt relative to the copper foil. Then, the tearing moving part 931 drives the tearing clamp 932 to move to the tilted corner of the protective paper, and the tearing clamp 932 clamps the protective paper, and then the tearing moving part 931 drives the tearing clamp 932 to move back, so that the protective paper is lifted and separated from the copper foil. After completing the paper tearing operation, the control device 80 controls the intermediate platform 42 to return from the paper tearing station to the film pasting station, and then the film pasting adsorption plate 53 transfers the product parts from the film pasting station to the placement seat 31 at the second station, and then the unloading structure 62 transfers the product parts on the placement seat 31 at the second station to the unloading seat 61 for storage.

[0042] like Figure 1 As shown, in order to prevent dust from falling on the surface of the product workpiece and causing pollution during the copper foil laminating process in order to prevent various parts of the film laminating machine from being dust-proof so as to ensure the cleanliness of the processing environment, the film laminating machine of the present invention also includes a protective cover 200.

The first loading mechanism 20, the loading and conveying mechanism 30, the second loading mechanism 40, the film laminating mechanism 50 and the unloading mechanism 60 are all located in the assembly space.
