Description

Technical Field

[0001] The invention relates to the technical field of copper foil attaching devices, and in particular to a copper foil attaching device on a PET substrate. Background Art

[0002] Laminating a certain thickness of copper foil on one or both sides of the PET substrate is the basis for obtaining the circuit layer later. As a conductive material, PET copper foil can be used to make flexible circuits, smartphone antennas, flexible displays, etc. Copper foil has good conductivity and can be bent and folded through the flexibility of the PET substrate to adapt to various forms of devices. At the same time, PET copper foil has good electromagnetic wave shielding performance and can be used to make electromagnetic shielding materials to protect electronic equipment from interference from external electromagnetic radiation. In electronic products, using PET copper foil as a shielding material can improve the anti-interference performance of the equipment.

[0003] During the copper foil attachment process, glue is usually applied between the PET substrate and the copper foil. Since bubbles may exist during the glue application process, affecting the adhesion between the PET substrate and the copper foil, the bubbles are usually expelled by squeezing after the glue is applied. The method of expelling bubbles by squeezing may affect the uniform distribution of the glue during the bubble expulsion process, thereby affecting the tightness of the PET substrate and the copper foil. Summary of the invention

[0004] The present invention discloses a copper foil attaching device on a PET substrate, which aims to solve the problem that bubbles may exist in the glue coating process, affecting the adhesion between the PET substrate and the copper foil. Generally, bubbles are expelled by squeezing after the glue is coated. However, the method of expelling bubbles by squeezing may affect the uniform distribution of glue during the bubble discharge process, thereby affecting the tightness of the PET substrate and the copper foil.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A copper foil attaching device on a PET substrate comprises a base, wherein a coating mechanism, a guide roller group, an exhaust mechanism, a cleaning mechanism and an extrusion roller group are sequentially arranged at the top of the base from left to right, and the exhaust mechanism is fixed to the base through a first connecting frame; the exhaust mechanism comprises a first supporting shell, and a plurality of synchronous wheels are equidistantly connected to the top of the first supporting shell through a bearing seat, and a plurality of synchronous wheels are simultaneously connected to a synchronous belt, one side of one of the synchronous wheels is connected to a second gear through a support shaft, the second gear is meshed with the first gear, and a stepping motor is connected to one side of the first gear; eccentric support shafts are respectively fixedly connected to the outer walls of the same side of the plurality of synchronous wheels, and the eccentric support shafts on adjacent synchronous wheels are staggered, and each of the eccentric support shafts is staggered. The shafts are movably connected with connecting rods, and the bottom end of each connecting rod is hinged with an articulated rod, and the bottom end of each articulated rod is fixedly connected with a mounting frame, and the inner walls on the opposite sides of the mounting frame are simultaneously connected with a plurality of track wheels through ball bearings, and the plurality of track wheels are simultaneously connected with tracks, and the top of the first support shell is penetrated with a plurality of position-limiting through-holes, and the plurality of articulated rods are respectively movably inserted into the position-limiting through-holes; the opposite sides of the first support shell are respectively connected with side track wheel groups through the second connecting frame, and the side track wheel groups are clamped on both sides of the PET substrate and the copper foil, the bottom end of the second connecting frame is simultaneously connected with a bottom plate, and the bottom plate is attached to the bottom end of the PET substrate and the copper foil, and an electric heater is installed on the inner wall of the bottom end of the first support shell;

[0008] By providing an exhaust mechanism, when it moves to the bottom end of the first supporting shell, a heating chamber is formed at the bottom end of the first supporting shell under the heating action of the electric heater, thereby enhancing the fluidity of the glue. During the movement, the top ends of the PET substrate and the copper foil are repeatedly beaten by multiple mounting frames. Under the simultaneous action of beating and enhancing the fluidity of the glue, the bubbles in the glue can be effectively discharged and the glue can be evenly distributed. Compared with the method of directly squeezing out the bubbles, this method can ensure that the uniform extension of the glue will not be affected when the bubbles are discharged.

When the machine is not in use, the glue between the upper extrusion frame and the lower extrusion frame is easily blocked by solidification of glue, and small particles in the air are easily adhered, thereby affecting the next use of glue coating. When the use is finished, the bottom slide plate is pulled out through the tool fixing card interface.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The copper foil attaching device on a PET substrate disclosed by the present invention is mainly used in the scenario of attaching copper foil on a PET substrate.

[0026] Reference Figure 1-Figure 3A copper foil attaching device on a PET substrate comprises a base 1, a coating mechanism 7, a guide roller group 6, an exhaust mechanism 3, a cleaning mechanism 4 and a squeeze roller group 5 are sequentially arranged on the top of the base 1 from left to right, and the exhaust mechanism 3 is fixed to the base 1 through a first connecting frame 2; the exhaust mechanism 3 comprises a first supporting shell 301, and a plurality of synchronous wheels 315 are equidistantly connected to the top of the first supporting shell 301 through a bearing seat 314, and a synchronous belt 316 is simultaneously connected to the outside of the plurality of synchronous wheels 315, one side of one of the synchronous wheels 315 is connected to a second gear 312 through a support shaft 313, the second gear 312 is meshed with a first gear 311, and one side of the first gear 311 is connected to a stepping motor 310; The outer walls of the same side of the multiple synchronous wheels 315 are respectively fixedly connected with eccentric support shafts 317, and the eccentric support shafts 317 on adjacent synchronous wheels 315 are staggered, each eccentric support shaft 317 is respectively movably connected with a connecting rod 318, and the bottom end of each connecting rod 318 is respectively hinged with a hinge rod 322, and the bottom end of each hinge rod 322 is respectively fixedly connected with a mounting frame 320, and the inner walls on the opposite sides of the mounting frame 320 are simultaneously connected with multiple track wheels 323 through ball bearings 324, and the multiple track wheels 323 are simultaneously connected with track 325, and the top of the first support shell 301 is penetrated with multiple limit through holes 321, and the multiple hinge rods 322 are respectively movably inserted into the limit through holes 321;The opposite sides of the first support shell 301 are connected with side track wheel groups 303 through the second connecting frame 302, and the side track wheel groups 303 are clamped on both sides of the PET substrate and the copper foil. The bottom end of the second connecting frame 302 is also connected with a bottom plate 304, and the bottom plate 304 is attached to the bottom end of the PET substrate and the copper foil. The inner wall of the bottom end of the first support shell 301 is installed with an electric heater 319. When the PET substrate and the copper foil are guided by the guide roller group 6, and UV glue is coated between the PET substrate and the copper foil by the coating mechanism 7, and then overlapped together, they enter the exhaust mechanism 3. When it moves to the bottom end of the first support shell 301, under the heating action of the electric heater 319, a heating chamber is formed at the bottom end of the first support shell 301 to enhance the fluidity of the glue. In the process of moving, the first gear 311 and the second gear 312 are driven to rotate by the stepping motor 310, thereby synchronously driving multiple synchronous wheels 315 through the synchronous belt 316. Rotation, based on the setting of the eccentric support shaft 317, the height of one end of the connecting rod 318 is driven to change in a rotational manner, and based on the vertical limit of the hinge rod 322 by the limit perforation 321, the mounting frame 320 can be driven to move up and down. Based on the support provided by the bottom plate 304 to the bottom of the PET substrate and the copper foil, the top of the PET substrate and the copper foil can be repeatedly slapped by multiple mounting frames 320. Under the synchronous action of slapping and enhancing the fluidity of the glue, the bubbles in the glue can be effectively discharged and the glue can be evenly distributed. Compared with the method of directly squeezing out bubbles, this method can ensure that the uniform extension of the glue will not be affected when the bubbles are discharged. In addition, based on the crawler wheel 323 and crawler 325 set at the bottom of the mounting frame 320, the friction at the connection of the crawler wheel 323 is reduced by the ball bearing 324, and the PET substrate and copper foil in the moving process will not be blocked during the up and down slapping process, so as to ensure the normal transportation of the PET substrate and copper foil. ;

[0027] Reference Figure 2 and Figure 3 In a preferred embodiment, the outer walls on both sides facing each other of the first supporting shell 301 are respectively fixedly connected with the first extension frame 306, and the bottom end of the first extension frame 306 is provided with a dustproof sheet 305, and the other outer walls on both sides facing each other of the first supporting shell 301 are respectively fixedly connected with the second extension frame 309.

[0028] Reference Figure 2 and Figure 3In a preferred embodiment, the bottom end of the second extension frame 309 is connected with a brush 308 and an inner baffle 307, the inner baffle 307 is located on the inner side of the side track wheel group 303, and the brush 308 is attached to the top of the side track wheel group 303. The dustproof sheet 305 is arranged to make the bottom of the first support shell 301 relatively sealed, so that the electric heater 319 heats the heating chamber at the bottom of the first support shell 301. The top of the side track wheel group 303 is cleaned by the brush 308 to avoid the presence of small particles such as dust on the surface of the side track wheel group 303, which may cause damage to the PET substrate and the copper foil surface during the extrusion process. At the same time, the inner baffle 307 can prevent the dust on the brush 308 from entering the heating chamber and affecting the subsequent extrusion effect while assisting in forming a relatively sealed state.

[0029] Reference Figure 5-Figure 7 In a preferred embodiment, the cleaning mechanism 4 includes a second supporting shell 407, and the second supporting shell 407 is fixed to one side of the bottom plate 304, a groove 403 is provided in the second supporting shell 407, and a plurality of springs 404 are symmetrically fixedly connected to the inner wall of the bottom end of the groove 403.

[0030] Reference Figure 5-Figure 7 In a preferred embodiment, the top ends of the plurality of springs 404 are simultaneously connected to a vibration plate 402, and a curved surface 401 is provided on one side of the vibration plate 402. The vibration plate 402 is provided at a position directly below the end mounting bracket 320, and the highest point of the vibration plate 402 is slightly higher than the top end of the base plate 304.

[0031] Reference Figure 5-Figure 7In a preferred embodiment, a collision block 405 is fixedly connected to the center position of the bottom end of the vibration plate 402, and a collision seat 406 is fixedly connected to the inner wall of the bottom end of the groove 403, and the collision block 405 is located in the collision seat 406.

Since the heating chamber at the bottom of the first supporting shell 301 is not completely sealed and its internal temperature is higher than the external ambient temperature, the pressure in the heating chamber is lower than the ambient pressure. Under the action of negative pressure, air enters the heating chamber and drives dust in the air into the heating chamber. If there are small particles such as dust on the surface of the PET substrate and the copper foil, after being squeezed, the air in the heating chamber is sucked out of the heating chamber. When the roller group 5 is squeezed, an indentation may be caused on the surface of the copper foil. In the cleaning mechanism 4, the vibration plate 402 corresponds to the mounting frame 320 at the end. When the PET substrate and the copper foil are slapped and moved to the bottom of the mounting frame 320 at the end, they hit the top of the vibration plate 402 through the mounting frame 320 at the end, driving the impact block 405 to hit the inner wall of the impact seat 406. In addition to rebounding, the spring 404 also absorbs the vibration force under the vibration generated by the impact, and releases the vibration force in a repeated rebounding manner, thereby driving the top of the vibration plate 402 to vibrate the PET substrate and the copper foil at the position of the squeezing roller group 5, so that the adhered dust is separated from the surface of the PET substrate and the copper foil, and then adsorbed by the electrostatic plate 408, so that the dust can be completely cleaned, ensuring the flatness of the surface of the PET substrate and the copper foil when the squeezing roller group 5 is squeezed.

[0033] Reference Figure 8 and Fig. 9 In a preferred embodiment, a scraping edge 718 is fixedly connected to one side of the bottom slide plate 706, and the bottom end of the scraping edge 718 is attached to the top of the lower extrusion frame 704, and one side of the upper extrusion frame 702 and the lower extrusion frame 704 is fixedly connected to the side covering plate 712 through a connecting pin 713.

[0035] Reference Figure 8 and Fig. 9 In a preferred embodiment, one end of the sealing film 715 is connected to the limiting plug rod 717 through a pull rope 716, a first limiting plug hole 705 is provided on one side of the bottom slide 706, and the limiting plug rod 717 is movably inserted into the first limiting plug hole 705, the bottom end of the lower extrusion frame 704 is connected to an L-shaped bracket 708 through a damping hinge seat 709, and a second limiting plug hole 707 is provided on the inner wall of one side of the L-shaped bracket 708, and the coating mechanism 7 is used to apply glue between the PET substrate and the copper foil, and when the machine is not in use, the glue between the upper extrusion frame 702 and the lower extrusion frame 704 is easily blocked by solidification of glue, and small particles in the air are easily adhered, thereby affecting the next use of glue coating, through the bottom slide The setting of 706 allows the glue to be squeezed out from between the bottom slide plate 706 and the lower extrusion frame 704 during glue coating. When use is finished, the bottom slide plate 706 is pulled out through the tool fixing card interface 719. Based on the setting of the scraper edge 718, the glue at the extrusion port can be discharged from one side of the upper extrusion frame 702 and the lower extrusion frame 704, and at the same time, the sealing film 715 is blocked at the extrusion port. When the bottom slide plate 706 is pulled out, the limiting plug rod 717 can be inserted into the second limiting plug hole 707 to fix the sealing film 715. Under this structure, the bottom slide plate 706 and the glue at the extrusion port can be easily cleaned, and at the same time, small particles can be prevented from entering from the extrusion port, thereby reducing the difficulty of preparing for the next work and ensuring the normal use of the glue.

[0036] Working principle: When the PET substrate and the copper foil are guided by the guide roller group 6, and UV glue is coated between the PET substrate and the copper foil by the coating mechanism 7, and then they are superimposed together and enter the exhaust mechanism 3, when they move to the bottom end of the first support shell 301, under the heating action of the electric heater 319, a heating chamber is formed at the bottom end of the first support shell 301 to enhance the fluidity of the glue, and during the movement, the first gear 311 and the second gear 312 are driven to rotate by the stepping motor 310, thereby synchronously driving multiple synchronous wheels 315 to rotate through the synchronous belt 316, and based on the setting of the eccentric support shaft 317, the height of one end of the connecting rod 318 is driven to change in a rotational manner, Based on the vertical limit of the hinge rod 322 by the limit perforation 321, the mounting frame 320 can be driven to move up and down. Based on the support provided by the bottom plate 304 to the bottom of the PET substrate and the copper foil, the top of the PET substrate and the copper foil can be repeatedly patted by multiple mounting frames 320. Under the synchronous action of patting and enhancing the fluidity of the glue, the bubbles in the glue can be effectively discharged and the glue can be evenly distributed. Compared with the method of directly squeezing out bubbles, this method can ensure that the uniform extension of the glue will not be affected when the bubbles are discharged. In addition, based on the track wheel 323 and the track 325 set at the bottom of the mounting frame 320, the track wheel 323 is connected to the ball bearing 324 to reduce the friction between the track wheel 323 and the track wheel 325. The friction force at the joint can prevent the PET substrate and copper foil from being blocked during the up and down beating process, thereby ensuring the normal transportation of the PET substrate and copper foil. Since the heating chamber at the bottom of the first supporting shell 301 is not completely sealed and its internal temperature is higher than the external ambient temperature, the pressure in the heating chamber is lower than the ambient pressure. Under the action of negative pressure, air enters the heating chamber and drives the dust in the air into the heating chamber. If there are small particles such as dust on the surface of the PET substrate and copper foil, it may cause indentations on the surface of the copper foil when passing through the squeezing roller group 5. In the cleaning mechanism 4, the vibration plate 402 corresponds to the mounting frame 320 at the end. When the PET substrate When the plate and copper foil are slapped and moved to the bottom of the last mounting frame 320, they hit the top of the vibration plate 402 through the last mounting frame 320, driving the impact block 405 to hit the inner wall of the impact seat 406. In addition to rebounding, the spring 404 also absorbs the vibration force generated by the impact and releases the vibration force by repeatedly rebounding, thereby driving the top of the vibration plate 402 to the PET substrate and copper foil at the position of the squeezing roller group 5 to vibrate, so that the adhered dust is separated from the surface of the PET substrate and copper foil, and then adsorbed by the electrostatic plate 408, so that the dust can be completely cleaned, ensuring the flatness of the surface of the PET substrate and copper foil when the squeezing roller group 5 is squeezed.
