Description

Technical Field

[0001] The present invention relates to the technical field of electronic materials, and particularly to an adjustment device for MPI material lamination. Background Art

[0002] With the advent of the 5G information era, wireless communication has evolved from 3G / 4G to the current 5G, and the speed and quality of signal transmission have increased by more than ten times. Therefore, the requirements for material characteristics also need to be innovated. In order to make electronic materials suitable for the high frequency and high speed of 5G, the prior art has proposed an MPI high-frequency flexible pure adhesive film and its preparation method and application (its publication number is "CN111961415A"). This MPI high-frequency flexible pure adhesive film has a three-layer structure, namely a release film layer, an MPI layer, and a release paper. When producing this MPI high-frequency flexible pure adhesive film, it is necessary to coat the MPI layer on the release film layer and then laminate the release paper, and then cure the laminated MPI high-frequency flexible pure adhesive film. After semi-finished product slitting and re-inspection, the finished product is obtained. The prior art has also proposed an MPI high-frequency and high-speed flexible substrate and its preparation method and application (its publication number is "CN111923519A"). This MPI high-frequency and high-speed flexible substrate, from the inside to the outside, is a high-frequency PI layer, an MPI layer, and a low-profile copper foil layer. When producing this MPI high-frequency and high-speed flexible substrate, it is necessary to coat and laminate the MPI layer on the high-frequency PI layer and then laminate the low-profile copper foil layer to obtain a semi-finished substrate; bake and cure the semi-finished substrate to obtain the finished substrate.

[0003] In the lamination process stage of the production of the above two MPI materials, it is necessary to accurately align the upper film and the lower film, and make the upper film accurately laminate and cover the lower film with the MPI layer. Therefore, it is necessary to propose an adjustment device for MPI material lamination to improve the lamination quality of the three-layer structure. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides an adjustment device for MPI material lamination that uses multiple independent sponge adsorption wheels with automatic control to adjust the upper film, improving the accuracy and quality of film lamination.

[0005] An adjustment device for laminating MPI materials of the present invention includes a frame and conveying rollers. The conveying rollers are installed on the frame, and the rotation of the conveying rollers conveys the lower film coated with the MPI layer backward. It further includes a shaft tube, a joint, air holes, and a sponge suction cup wheel. At least one shaft tube is provided. One end of each shaft tube is installed with a joint, and the joint is connected to a vacuum pumping system. A plurality of air holes are provided on the lower side walls at both ends of each shaft tube. A plurality of sponge suction cup wheels are respectively installed at both ends of the shaft tube. A driving mechanism is provided on the shaft tube. The driving mechanism drives the plurality of sponge suction cup wheels to rotate and move within the range of the plurality of air holes. The part of the sponge suction cup wheel aligned with the air hole generates negative pressure to adsorb the upper film. The rotation of the sponge suction cup wheel longitudinally tightens and conveys the upper film backward. The two sponge suction cup wheels on the same shaft tube move away from each other to laterally tighten the upper film. All the sponge suction cup wheels move synchronously in one direction to adjust the alignment state of the upper film and the lower film. The vacuum pumping system evacuates the shaft tube through the joint. The sponge suction cup wheel rotates under the drive of the driving mechanism. Since the air holes are located on the lower side wall of the shaft tube, the pores of the part of the air hole in contact with the sponge suction cup wheel are evacuated, so that the part of the lower wheel surface of the sponge suction cup wheel in contact with the upper film generates negative pressure, thereby adsorbing the upper film. As the sponge suction cup wheel rotates, the upper film is longitudinally tightened by the sponge suction cup wheel. The sponge suction cup wheel moves along the shaft tube under the action of the driving mechanism. When the two sponge suction cup wheels on the same shaft tube move away from each other synchronously, the two sponge suction cup wheels laterally tighten the upper film, thereby eliminating the wrinkles of the upper film. When the plurality of sponge suction cup wheels move synchronously in one direction along the plurality of shaft tubes, the plurality of sponge suction cup wheels move the upper film to one side to adjust the alignment position of the upper film and the lower film, so that the upper film and the lower film are aligned. It has various functions and improves the accuracy and quality of film lamination.

The plurality of lower covers respectively block the plurality of air holes exposed on both sides of the sponge suction cup wheel. By providing bearings, the sponge suction cup wheel can rotate smoothly and stably. By providing side covers, the sides of the sponge suction cup wheel are sealed, reducing air leakage from the sides, thereby improving the adsorption force of the wheel surface. By providing lower covers, air leakage from the plurality of air holes is reduced, further improving the adsorption force of the wheel surface.

The two mounting rings are respectively concentrically mounted on the outer side walls of two sponge suction cup wheels on the same shaft tube. A plurality of springs are evenly mounted on the two mounting rings. The plurality of springs elastically support the two pressing rings from the inside. The outer edges of the two pressing rings extend out of the wheel surfaces of the sponge suction cup wheels. The two pressing rings cooperate with the conveying roller to roll a pressing mark at the edge of the film pasting. Due to the elastic supporting effect of the plurality of springs, the edges of the two pressing rings extending out of the wheel surfaces of the sponge suction cup wheels press the film tightly on the conveying roller, so as to roll out pressing marks at both side edges of the film, facilitating subsequent cutting work.

The rotating component and the moving component are mounted on the slider. The slider is connected to the inner ring of the bearing. The rotating component drives the sponge suction cup wheel to rotate, and the moving component drives the slider to move along the shaft tube. The limiting cooperation between the slider and the limiting groove enables the slider not to rotate when sliding, and the movement is more stable. Arranging the rotating component and the moving component on the slider has a high integration degree and a small structural volume.

[0009] Preferably, the rotating component includes a servo motor I, a driving gear and a gear ring. The servo motor I is mounted on the slider.

The gear ring drives the sponge suction cup wheel to rotate through the outer ring of the bearing. The structure is simple, the rotation speed can be adjusted flexibly, and the conveying and tensioning effects of the upper film are improved.

[0010] Preferably, the moving component includes a half-threaded area, a servo motor II and a threaded cylinder. A half-threaded area is provided on the outer wall of the shaft tube.

The threaded cylinder meshes with the half-threaded area to drive the slider to move along the shaft tube. The slider drives the sponge suction cup wheel to move through the bearing. By adjusting the rotation speed and rotation direction of the servo motor II, the moving speed and moving direction of the sponge suction cup wheel can be adjusted. By setting parameters such as the pitch of the threads of the half-threaded area and the threaded cylinder, the moving precision of the slider can be adjusted.

[0011] Preferably, it further includes a plurality of grating scales and a plurality of grating heads. The grating scales are mounted on the plurality of shaft tubes, and the grating heads are mounted on the plurality of sliders. The grating heads and the grating scales cooperate to measure the displacement of the slider.

[0012] Preferably, it further includes a plurality of rangefinders, which are respectively installed in the middle of a plurality of shaft tubes. The plurality of rangefinders face downward, and the plurality of rangefinders measure the sag depth in the middle of the upper film. The control system of the device (not shown in the figure) controls the degree of the sponge suction cup wheels pulling the upper film horizontally according to the sag depth; by measuring the sag depth in the middle of the upper film with a plurality of rangefinders, when it is found that the sag depth is too large, the distance between the two sponge suction cup wheels on the same shaft tube is automatically adjusted to increase, so as to horizontally tighten the upper film, improving the automation degree and film pasting quality of the device.

[0013] Preferably, it further includes two CCD cameras, which are respectively installed on both sides of the frame through brackets. The two CCD cameras monitor the alignment of the edges of the lower film and the upper film above the conveying roller; in the monitoring images of the two CCD cameras, the edges of the upper film and the lower film above the conveying roller are two groups of lines, and each group of lines contains two upper and lower lines. When there is a large deviation between the upper and lower lines in the two groups of lines, the plurality of sponge suction cup wheels are automatically controlled to move in the same direction, so as to keep the upper and lower lines in the two groups of lines aligned, improving the automation degree and film pasting quality of the device.

[0014] Preferably, it further includes two screws. The brackets of the two CCD cameras are respectively fastened and installed on the frame through the two screws; by fastening the brackets of the two CCD cameras with the two screws, the monitoring angles of the two CCD cameras can be adjusted, improving the practicability.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The vacuum pumping system pumps the air in the shaft tube through the joint, and the sponge suction cup wheels rotate under the drive of the drive mechanism. Since the air holes are located on the lower side wall of the shaft tube, the pores of the part where the air holes contact the sponge suction cup wheels are pumped to create a negative pressure at the part where the lower wheel surface of the sponge suction cup wheel contacts the upper film, thereby adsorbing the upper film. As the sponge suction cup wheels rotate, the upper film is longitudinally tightened by the sponge suction cup wheels. The sponge suction cup wheels move along the shaft tube under the action of the drive mechanism. When the two sponge suction cup wheels on the same shaft tube move away synchronously, the two sponge suction cup wheels horizontally tighten the upper film, thereby eliminating the wrinkles of the upper film. When the plurality of sponge suction cup wheels move synchronously in the same direction along the plurality of shaft tubes, the plurality of sponge suction cup wheels move the upper film to one side to adjust the alignment position of the upper film and the lower film, so that the upper film and the lower film are aligned, with diverse functions and improved film pasting accuracy and quality.

The present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present invention is thorough and complete.

[0026] Embodiment

[0027] Such as Figure 1 , Figure 2 , Figure 3 And Figure 8As shown in the figure, an adjustment device for laminating MPI materials includes a frame 1 and a conveying roller 2. The conveying roller 2 is installed on the frame 1, and the rotation of the conveying roller 2 conveys the lower film coated with the MPI layer backward. It also includes a shaft tube 3, a joint 4, air vents 5, and a sponge suction cup wheel 6. At least one shaft tube 3 is provided. One end of each shaft tube 3 is installed with a joint 4, and the joint 4 is connected to a vacuum pumping system. A plurality of air vents 5 are provided on the lower side walls at both ends of each shaft tube 3. A plurality of sponge suction cup wheels 6 are respectively installed at both ends of the shaft tube 3. A driving mechanism is provided on the shaft tube 3, and the driving mechanism drives the plurality of sponge suction cup wheels 6 to rotate and move within the range of the plurality of air vents 5. The part of the sponge suction cup wheel 6 aligned with the air vent 5 generates negative pressure to adsorb the upper film. The rotation of the sponge suction cup wheel 6 longitudinally tightens and conveys the upper film backward. The two sponge suction cup wheels 6 on the same shaft tube 3 move away from each other to laterally tighten the upper film. All the sponge suction cup wheels 6 move synchronously in one direction to adjust the alignment state of the upper film and the lower film. It also includes a plurality of bearings 7, a plurality of side covers 8, and a plurality of lower covers 9. Bearings 7 are provided at both ends of the central hole of the sponge suction cup wheel 6. The inner rings of the plurality of bearings 7 are slidably sleeved on the shaft tube 3. Side covers 8 are provided on both sides of the sponge suction cup wheel 6, and the side covers 8 close the pores on both sides of the sponge suction cup wheel 6. Lower covers 9 are provided on the inner rings of the plurality of bearings 7, and the plurality of lower covers 9 respectively block the plurality of air vents 5 exposed on both sides of the sponge suction cup wheel 6. It also includes two mounting rings 10, a plurality of springs 11, and two pressing rings 12. The two mounting rings 10 are concentrically installed on the outer side walls of the two sponge suction cup wheels 6 on the same shaft tube 3. A plurality of springs 11 are evenly installed on the two mounting rings 10. The plurality of springs 11 elastically support the two pressing rings 12 from the inside. The outer edges of the two pressing rings 12 extend out of the wheel surface of the sponge suction cup wheel 6, and the two pressing rings 12 cooperate with the conveying roller 2 to roll a pressing mark at the edge of the film during laminating.

[0028] The vacuum pumping system evacuates the shaft tube 3 through the joint 4. The sponge suction cup wheel 6 rotates under the drive of the drive mechanism. Since the air vent holes 5 are located on the lower side wall of the shaft tube 3, the pores of the part of the air vent holes 5 in contact with the sponge suction cup wheel 6 are evacuated, so that a negative pressure is generated at the part where the lower wheel surface of the sponge suction cup wheel 6 contacts the upper film, thereby adsorbing the upper film. As the sponge suction cup wheel 6 rotates, the upper film is longitudinally tightened by the sponge suction cup wheel 6. The sponge suction cup wheel 6 moves along the shaft tube 3 under the action of the drive mechanism. When the two sponge suction cup wheels 6 on the same shaft tube 3 move away synchronously, the two sponge suction cup wheels 6 laterally tighten the upper film, thereby eliminating the wrinkles of the upper film. When multiple sponge suction cup wheels 6 move synchronously along multiple shaft tubes 3 in one direction, the multiple sponge suction cup wheels 6 move the upper film to one side to adjust the alignment position of the upper film and the lower film, so that the upper film and the lower film are aligned. It has various functions, improves the precision and quality of film pasting. By setting the bearing 7, the sponge suction cup wheel 6 can rotate smoothly and stably. By setting the side cover plate 8, the wheel side of the sponge suction cup wheel 6 is sealed, reducing air leakage on the side, thereby increasing the adsorption force of the wheel surface. By setting the lower cover plate 9, air leakage from multiple air vent holes 5 is reduced, further increasing the adsorption force of the wheel surface. Due to the elastic support of multiple springs 11, the two pressure rings 12 extend out of the edge of the wheel surface of the sponge suction cup wheel 6 to press the film tightly on the conveying roller 2, thereby rolling out indentations at both side edges of the film pasting, facilitating subsequent cutting work.

[0029] As Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the drive mechanism includes a slider 13, a limit groove 17, a rotation assembly and a movement assembly. A limit groove 17 is provided on the outer wall of the shaft tube 3. The slider 13 is slidably installed on the shaft tube 3. The slider 13 is provided with a limit block matching the limit groove 17. The limit block slides in the limit groove 17. The rotation assembly and the movement assembly are installed on the slider 13. The slider 13 is connected to the inner ring of the bearing 7. The rotation assembly drives the sponge suction cup wheel 6 to rotate, and the movement assembly drives the slider 13 to move along the shaft tube 3; the rotation assembly includes a servo motor 14, a driving gear 15 and a gear ring 16. The servo motor 14 is installed on the slider 13. The output shaft of the servo motor 14 is concentrically installed with the driving gear 15. The limit groove 17 is concentrically installed on the outer ring of the bearing 7. The driving gear 15 meshes with the gear ring 16; the movement assembly includes a half-threaded area 18, a servo motor 19 and a threaded cylinder 20. A half-threaded area 18 is provided on the outer wall of the shaft tube 3. The servo motor 19 is installed on the slider 13. The output shaft of the servo motor 19 is concentrically installed with the threaded cylinder 20. The wheel surface of the threaded cylinder 20 is provided with threads, and the threads mesh with the half-threaded area 18; it also includes multiple grating scales 21 and multiple grating heads 22. The grating scales 21 are installed on multiple shaft tubes 3, and the grating heads 22 are installed on multiple sliders 13. The grating heads 22 and the grating scales 21 cooperate to measure the displacement of the slider 13.

[0030] The limiting fit between the slider 13 and the limiting groove 17 enables the slider 13 not to rotate when sliding, making the movement more stable. Arranging the rotating component and the moving component on the slider 13 has a high integration degree and a small structural volume. The servo motor 1 drives the driving gear 15 to rotate, and the driving gear 15 meshes with and drives the gear ring 16 to rotate. The gear ring 16 drives the sponge suction cup wheel 6 to rotate through the outer ring of the bearing 7. The structure is simple, and the rotation speed can be flexibly adjusted, improving the conveying and tensioning effects of the upper film. The servo motor 2 drives the threaded cylinder 20 to rotate, and the threaded cylinder 20 meshes with the semi-threaded area 18 to drive the slider 13 to move along the shaft tube 3. The slider 13 drives the sponge suction cup wheel 6 to move through the bearing 7. By adjusting the rotation speed and rotation direction of the servo motor 2, the moving speed and moving direction of the sponge suction cup wheel 6 can be adjusted. By setting parameters such as the pitch of the threads of the semi-threaded area 18 and the threaded cylinder 20, the moving precision of the slider 13 can be adjusted. The displacement of the slider 13 is measured by the grating ruler 21 and the grating head 22, further improving the moving precision of the sponge suction cup wheel 6.

[0031] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, it further includes a plurality of rangefinders 23, and the plurality of rangefinders 23 are respectively installed in the middle parts of the plurality of shaft tubes 3. The plurality of rangefinders 23 face downward, and the plurality of rangefinders 23 measure the sag depth in the middle of the upper film. The control system of the device controls the degree of laterally tensioning the upper film by the sponge suction cup wheel 6 according to the sag depth; it further includes two CCD cameras 24, and the two CCD cameras 24 are respectively installed on both sides of the frame 1 through brackets. The two CCD cameras 24 monitor the alignment of the edges of the lower film and the upper film above the conveying roller 2; it further includes two screw rods 25, and the brackets of the two CCD cameras 24 are respectively fixedly installed on the frame 1 through the two screw rods 25.

[0032] The sag depth in the middle of the upper film is measured by the plurality of rangefinders 23. When it is found that the sag depth is too large, the distance between the two sponge suction cup wheels 6 on the same shaft tube 3 is automatically adjusted to increase, thereby laterally tensioning the upper film. By tightening the brackets of the two CCD cameras 24 with the two screw rods 25, the monitoring angles of the two CCD cameras 24 can be adjusted. In the monitoring images of the two CCD cameras 24, the edges of the upper film and the lower film above the conveying roller 2 are two groups of lines, and each group of lines contains two upper and lower lines. When there is a large deviation between the upper and lower lines in the two groups of lines, the plurality of sponge suction cup wheels 6 are automatically controlled to move in the same direction, thereby keeping the upper and lower lines in the two groups of lines aligned, improving the automation degree and film pasting quality of the device, and improving the practicability.

[0033] As Figures 1 to 8As shown in the figure, an adjustment device for MPI material lamination of the present invention, when working, first the vacuum pumping system pumps the air in the shaft tube 3 through the joint 4. The servo motor 1 drives the driving gear 15 to rotate. The driving gear 15 meshes with and drives the gear ring 16 to rotate. The gear ring 16 drives the sponge suction cup wheel 6 to rotate through the outer ring of the bearing 7. Since the air vent holes 5 are located on the lower side wall of the shaft tube 3, the pores of the part of the air vent holes 5 in contact with the sponge suction cup wheel 6 are pumped to vacuum, so that a negative pressure is generated at the part of the lower wheel surface of the sponge suction cup wheel 6 in contact with the upper layer film, thereby adsorbing the upper layer film. Then, as the sponge suction cup wheel 6 rotates, the upper layer film is longitudinally tightened by the sponge suction cup wheel 6. The servo motor 2 drives the threaded cylinder 20 to rotate. The threaded cylinder 20 meshes with the semi-threaded area 18 to drive the slider 13 to move along the shaft tube 3. The slider 13 drives the sponge suction cup wheel 6 to move through the bearing 7. Then, the sag depth of the middle part of the upper layer film is measured by multiple rangefinders 23. When it is found that the sag depth is too large, the distance between the two sponge suction cup wheels 6 on the same shaft tube 3 is automatically adjusted to increase, so as to laterally tighten the upper layer film and eliminate the wrinkles of the upper layer film at the same time. Finally, in the monitoring images of the two CCD cameras 24, when there is a large deviation between the upper and lower lines of the two groups of lines, the multiple sponge suction cup wheels 6 are automatically controlled to move the upper layer film to one side to adjust the alignment position of the upper layer film and the lower layer film, so that the upper layer film and the lower layer film are aligned.
