Description

Technical Field

[0001] The invention relates to the technical field of circuit board edge folding and laminating, in particular to an aluminum etched flexible circuit board edge folding and laminating device. Background Art

[0002] Etching is a widely used method to produce flexible circuit boards. Aluminum etched flexible circuit boards refer to the process of coating the surface of aluminum substrates with a certain thickness of chemical copper plating, and then etching it using a special process to form metal circuits and electronic components. Aluminum etched flexible circuit boards use flexible materials and have the advantages of being light, thin, and foldable, and can replace the space occupied by traditional circuit boards.

[0003] When the folding and laminating device is used to fold and laminate the aluminum etched flexible circuit board, the surface of the aluminum etched flexible circuit board needs to be cleaned. However, the existing folding and laminating device does not clean the surface of the aluminum etched flexible circuit board properly. A small amount of dust will still adhere to the surface of the aluminum etched flexible circuit board after cleaning. In addition, glue needs to be sprayed on the laminating surface before laminating. The glue spraying is uneven. All of the above will lead to the subsequent laminating of the aluminum etched flexible circuit board surface. The laminating film and the surface of the aluminum etched flexible circuit board are not firmly adhered. For this reason, we have introduced an folding and laminating device for aluminum etched flexible circuit boards. Summary of the invention

[0040] A driving roller mechanism for driving the flexible circuit board 22 to move backward is provided behind the upper and lower cleaning rollers 14, and a folding and laminating mechanism is provided behind the driving roller mechanism. The folding and laminating mechanism is used to bend the side of the flexible circuit board 22 upward and then press the laminating film 23 on the upper surface of the flexible circuit board 22;

[0041] The cleaning roller 14, the driving roller mechanism, the folding and laminating mechanism and the winding wheel 10 are driven by a driving mechanism to work synchronously, and a nozzle mechanism is also provided above the folding and laminating mechanism;

[0042] A negative pressure mechanism 7 is also provided on the side of the corresponding horizontal frame 5. When the cleaning roller 14 rotates, negative pressure is generated inside the negative pressure mechanism 7, and dust on the surface of the flexible circuit board 22 is adsorbed through the opening 142 on the cleaning roller 14. At the same time, the negative pressure mechanism 7 realizes periodic pressurization of the nozzle mechanism, so that the glue in the nozzle mechanism is sprayed on the lower end surface of the coating 23.

[0043] The driving roller mechanism includes an upper driving roller 17 and a lower driving roller 16 movably connected between two sets of vertical frames 15, and the flexible circuit board 22 passes through between the upper driving roller 17 and the lower driving roller 16;

[0044] The folding and laminating mechanism comprises a support plate 21 connected to the bottom between the two sets of horizontal frames 5, an arc-shaped folding plate 19 fixed to the top of the end of the support plate 21, and a laminating roller 20 movably connected between the two sets of horizontal frames 5, and the laminating roller 20 is located above the support plate 21 and behind the arc-shaped folding plate 19;

[0045] The flexible circuit board 22 passes through between the support plate 21 and the coating roller 20, and the front and rear end openings of the arc-shaped folding plate 19 gradually shrink. In this way, when the flexible circuit board 22 moves backward, the side of the flexible circuit board 22 is in contact and squeezed with the inner wall of the arc-shaped folding plate 19, so that the side of the flexible circuit board 22 is bent upward.

[0048] The second transmission mechanism 2 includes a first gear 201 fixed after the third rotating shaft passes through the horizontal frame 5, a second gear 202 and a fifth pulley 203 fixed after the fourth rotating shaft passes through the horizontal frame 5 in the middle of the lower driving roller 16, a third gear 208 and a sixth pulley 209 movably connected to the outer wall of the corresponding vertical frame 15, a seventh pulley 205 fixed after the fifth rotating shaft passes through the horizontal frame 5 at the right end of the upper cleaning roller 14, and an eighth pulley 206 fixed after the sixth rotating shaft passes through the horizontal frame 5 at the right end of the lower cleaning roller 14;

[0049] The second gear 202 is meshed between the first gear 201 and the third gear 208 . The third belt 204 is connected between the fifth pulley 203 and the seventh pulley 205 . The fourth belt 207 is connected between the sixth pulley 209 and the eighth pulley 206 .

[0050] The negative pressure mechanism 7 comprises a sealing shell 71 fixed to the outer side of the corresponding horizontal frame 5, a tensioning wheel 78 and a ninth pulley 77 movably connected inside the sealing shell 71, a negative pressure blade 75 fixed to the left end of the ninth pulley 77, a tenth pulley 81 fixed after the left end of the third rotating shaft passes through the horizontal frame 5, and an air pressure tank 74 fixed to the upper end of the rear part of the sealing shell 71;

[0051] The tenth belt pulley 81 is located inside the sealing shell 71, the diameter of the tenth belt pulley 81 is larger than the diameter of the ninth belt pulley 77, a fifth belt 79 is connected between the tenth belt pulley 81 and the ninth belt pulley 77, and the tensioning wheel 78 is pressed against the top of the fifth belt 79;

[0052] The tenth pulley 81 is provided with an arc-shaped protrusion 80 on the side, and a piston 85 is provided inside the air pressure tank 74. The lower end of the piston 85 is connected to a piston rod 83. The bottom of the piston rod 83 extends into the sealing shell 71 and is connected to a roller seat 84. The roller seat 84 is movably connected with a roller 82. The bottom of the roller 82 contacts the top of the side of the tenth pulley 81.

[0053] A filter housing 72 is fixed to the outside of the front of the sealing housing 71, a filter screen 76 is provided inside the filter housing 72, and the top of the filter housing 72 is connected to the upper side of the air pressure tank 74 through a first air guide pipe 73;

[0054] The left end of the cleaning roller 14 is connected to a hollow rotating cylinder 143 . The hollow rotating cylinder 143 penetrates the horizontal frame 5 and extends into the sealing shell 71 . The hollow rotating cylinder 143 is connected to the opening 142 through a channel inside the cleaning roller 14 .

[0055] The nozzle mechanism includes a plurality of nozzle groups 11 connected to the rear end of the glue box 8 and a second air guide pipe 12 connected to the top of the air pressure tank 74 at the front end of the glue box 8 .

[0056] An air guide groove 86 is provided on the front outer side wall of the sealing shell 71 , and the air guide groove 86 allows the filter housing 72 and the sealing shell 71 to communicate with each other.

[0057] Specifically, when in use, the motor 18 drives the laminating roller 20 to rotate counterclockwise through the second rotating shaft. Since the first belt pulley 301 and the third belt pulley 303 are connected with the first belt 302, and the second belt pulley 306 and the fourth belt pulley 305 are connected with the second belt 304, the laminating roller 20 rotates counterclockwise to drive the upper driving roller 17 and the winding wheel 10 to rotate counterclockwise synchronously.

[0058] The reel 10 rotates counterclockwise to re-reel the coated flexible circuit board 22;

[0059] Since the second gear 202 is meshed between the first gear 201 and the third gear 208, the third belt 204 is connected between the fifth pulley 203 and the seventh pulley 205, and the fourth belt 207 is connected between the sixth pulley 209 and the eighth pulley 206, the upper cleaning roller 14 and the lower driving roller 16 rotate synchronously clockwise, and the lower cleaning roller 14 rotates synchronously counterclockwise;

[0060] The reel 10 rotates counterclockwise to pull the flexible circuit board 22 backward, and the side of the flexible circuit board 22 moves backward along the inside of the U-shaped brush seat 13, so that the U-shaped brush seat 13 cleans the side of the flexible circuit board 22;

[0061] The upper cleaning roller 14 rotates clockwise and the lower cleaning roller 14 rotates counterclockwise, and the soft cleaning convex plate 141 on the cleaning roller 14 cleans the dust on the upper and lower surfaces of the flexible circuit board 22, so that the upper and lower surfaces of the flexible circuit board 22 are cleaned, which is conducive to the covering film 23 covering and sticking to the upper surface of the flexible circuit board 22 after the side of the flexible circuit board 22 is folded upward;

[0062] Through the counterclockwise rotation of the upper driving roller 17 and the clockwise rotation of the lower driving roller 16, after the flexible circuit board 22 passes through the upper driving roller 17 and the lower driving roller 16, the flexible circuit board 22 can be driven backward. At the same time, the counterclockwise rotation of the coating pressure roller 20 also drives the flexible circuit board 22 backward, which can ensure that the flexible circuit board 22 moves backward and ensures that the flexible circuit board 22 will not break, avoiding the flexible circuit board 22 from breaking only when the winding wheel 10 winds up the flexible circuit board 22.

[0063] When the upper driving roller 17 rotates counterclockwise, it will synchronously drive the tenth pulley 81 to rotate in the sealing shell 71. Since the diameter of the tenth pulley 81 is greater than the diameter of the ninth pulley 77, and a fifth belt 79 is connected between the tenth pulley 81 and the ninth pulley 77, the tenth pulley 81 can drive the negative pressure blade 75 on the ninth pulley 77 to rotate at a high speed, thereby forming a negative pressure in the sealing shell 71.

[0064] Due to the negative pressure inside the sealing shell 71, while the soft cleaning convex plate 141 on the cleaning roller 14 cleans the dust on the upper and lower surfaces of the flexible circuit board 22, the dust then enters the sealing shell 71 through the opening 142, the channel inside the cleaning roller 14 and the hollow drum 143;

[0065] The dust and the air in the sealing shell 71 enter the filter housing 72 through the air guide groove 86, and under the filtering action of the filter screen 76, the dust falls into the filter housing 72, and the air filtered by the filter screen 76 enters the air pressure tank 74 through the first air guide pipe 73;

[0066] As the air continues to enter the air pressure tank 74, pressure is formed in the air pressure tank 74, so that the air pushes the piston 85 downward, and the piston rod 83, the roller seat 84 and the roller 82 at the lower end of the piston 85 move downward synchronously. At this time, the roller 82 is still rolling on the top of the side of the tenth pulley 81;

[0067] As the tenth pulley 81 rotates, the roller 82 quickly rolls onto the arc-shaped protrusion 80 on the tenth pulley 81, so that the roller 82, the roller seat 84, the piston rod 83 and the piston 85 move up synchronously and quickly, and the piston 85 quickly compresses the air inside the air pressure tank 74, so that the compressed air enters the glue box 8 through the second air guide pipe 12, and the glue in the glue box 8 is sprayed out through the nozzle 11, so that the glue is evenly sprayed and covered on the lower end surface of the coating 23, which is conducive to improving the quality of subsequent adhesion between the coating 23 and the surface of the flexible circuit board 22.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
