Description

Technical Field

[0001] The invention relates to the field of flexible circuit board manufacturing process, and in particular to a flexible circuit board exposure machine with a substrate clamping and deviation correcting mechanism. Background Art

[0002] The existing flexible circuit board exposure machine includes an unwinding device, an exposure device and a winding device. The unwinding device is used to unwind the flexible circuit board substrate, the exposure device is used to expose the flexible circuit board substrate at the exposure station, and the winding device is used to wind up the flexible circuit board substrate. Among them, the exposure device is located between the unwinding device and the winding device, and the winding device includes a winding roller. When the winding roller rotates, it pulls the flexible circuit board substrate so that the exposed part of the flexible circuit board substrate is moved out of the exposure station, and the unexposed section of the flexible circuit board substrate is pulled into the exposure station. However, when the winding roller is exposed, it is easy to have deviations during the long-term transportation of the flexible circuit board, and the displacement of the flexible circuit board substrate cannot be accurately controlled, so it is urgent to improve this situation.

[0003] In the prior art, the Chinese utility model patent with application number CN202120342135.1 relates to a flexible circuit board exposure machine capable of step-feeding, the exposure machine comprising an unwinding device, an exposure device and a feeding device; the feeding device comprises a first clamping mechanism and a second clamping mechanism, both of which are arranged on the side of the exposure device away from the unwinding device, and the first clamping mechanism is closer to the exposure device relative to the second clamping mechanism; wherein the first clamping mechanism is movable, and the first clamping mechanism is used to clamp the flexible circuit board substrate in the initial position and move toward the second clamping mechanism to pull the unexposed section of the flexible circuit board substrate into the exposure station; the second clamping mechanism is used to clamp the flexible circuit board substrate when the first clamping mechanism returns to the initial position. According to the scheme of the utility model, it can realize step-feeding of the flexible circuit board substrate, so that the flexible circuit board substrate is fed into the exposure station section by section, and its displacement accuracy is higher.

[0004] Although the above patent solves the problem that the flexible circuit board is easily pulled over during exposure, there is another situation during transportation: after a long period of transportation, the conveying roller is prone to cause the conveying to deviate from the center, affecting exposure. The existing correction structure mostly sets squeezing rollers on both sides of the circuit board to correct the circuit board. However, due to the precision of the circuit board, if squeezed, it is easy to cause bending, which in turn easily causes damage to the circuit. Therefore, a gentle correction device that does not damage the substrate is needed.

[0005] Therefore, it is necessary to invent a flexible circuit board exposure machine with a substrate clamping and correcting mechanism to solve the above problems. Summary of the invention

[0029] In the above technical solution, compared with the prior art, the technical effects and advantages provided by the present invention are as follows:

[0030] 1. Preliminary anti-deviation: The anti-deviation component is used to set the flexible circuit board to prevent deviation. Since the diameter of the elliptical block at the center is larger than the diameter at both ends, according to the principle of tightness, the flexible circuit board can be located in the middle of the elliptical block, thereby performing preliminary calibration of the flexible circuit board. The diameters of the two ends and the middle of the elliptical block are not much different, which prevents deformation and damage to the substrate.

[0031] 2. Correction before exposure: the angle of the correction roller is adjusted by the preliminary correction component according to the signal received from the first sensing component. When adjusting the angle, the correction block is driven to slide inside the installation box by starting the hydraulic cylinder, wherein the inner top of the installation box is provided with a slide rail slidably connected to the limit block, so as to limit the correction block, wherein the sliding of the correction block drives the compensation rod and the rotating ball to move inside the installation box, and since the rotating ball is rotatably connected to the rotating groove, the arc block can be driven to move inside the installation box, since the arc block and the arc groove are both arc-shaped, the arc plate can only move in an arc shape, so that the arc plate pulls the rotating ball to move, so that the compensation rod slides inside the installation box, and then the movable compensation is performed, wherein the arc blocks on both sides of the correction roller have the same curvature and the centers of the two arc blocks coincide, so that the correction roller rotates, and then the position of the substrate on the top thereof is adjusted, and the tension on both sides of the substrate is adjusted, wherein the interior of the arc groove is provided with a rotating bead, so as to reduce friction, which is beneficial to the operation of the device, and since the interaction amplitude of the correction roller is small, the substrate will not be damaged;

[0032] 3. Adjustment of the correction range. Since the initial correction component has a small range of motion, in order to compensate for the range of motion of the initial correction component, the compensation component is installed on the beam when installing it. In the initial state, the installation box is in a horizontal state, and the movement track of the initial correction component is as follows: Fig. 20As shown in the left figure, when the range of movement of the deviation correction roller needs to be expanded, the user can rotate the adjustment slot so that the rotating disk drives the threaded rod to rotate, and then the threaded rod drives the lifting rod to rise and fall. The bottom of the lifting rod is slidably connected to the adjustment slot, and then the adjustment plate can be driven to rotate, thereby adjusting the contact angle between the adjustment plate and the beam, and then adjusting the angle between the installation box and the support shell. At this time, the activity trajectory of the preliminary deviation correction component is as follows Fig. 20 As shown in the right figure, the adjustment range is expanded, and the adjustment range can be set according to the material of the substrate;

[0033] 4. Precise deviation correction during exposure. When the substrate is transported between the exposure bottom plate and the exposure top plate, the photosensitive sensor is started to detect the side of the substrate, and the rotation angle of the precision adjustment component is adjusted according to the detected position. When the installation top plate is in the process of descending, the photosensitive sensor continues to detect and adjusts the angle in real time according to the detection result. Then the substrate is fixed by the clamping block, which further improves the accuracy of the device without damaging the substrate. The top of the upper protective plate is rotatably connected to the fixed top plate. The rotating ball can reduce friction and improve rotation lubrication, thereby adjusting the exposure angle.

[0069] The conveying assembly 002 is arranged inside the supporting housing 001 and is used to convey the flexible circuit board;

[0070] The anti-deviation component 003 is arranged inside the feed housing 102 and is used to prevent the flexible circuit board from running off;

[0071] The preliminary deviation correction component 004 is arranged inside the feed housing 102 and at the output end of the deviation prevention component 003, and is used to perform preliminary pre-deflection correction on the deviated flexible circuit board. A compensation component 005 is arranged inside the compensation component 005, and is used to adjust the angle of the preliminary deviation correction component 004;

[0072] The first sensing component 006 is arranged at the output end of the preliminary deflection correction component 004, and is used to detect the deviation of the circuit board, and is connected to the preliminary deflection correction component 004 by signal;

[0073] The precision adjustment component 007 is installed inside the exposure housing 104 for further precise deviation correction;

[0074] The exposure component 008 is arranged inside the precision adjustment component 007 and is used for performing exposure processing on the flexible circuit board;

[0075] The second sensing component 009 is arranged inside the precision adjustment component 007 and is used for positioning the circuit board.

[0076] The conveying component 002 includes a feed roller 201, the feed roller 201 is used for unwinding, a transmission roller 1 202 is arranged on the side of the feed roller 201, a transmission roller 203 is arranged on the side of the transmission roller 1 202, a transmission roller 3 204 is arranged between the preliminary deviation correction component 004 and the first sensing component 006, a transmission roller 4 205 is arranged on the right side of the first sensing component 006, a transmission roller 5 206 is arranged at the input end of the discharge housing 103, a transmission roller 6 207 is arranged on the side of the transmission roller 5 206, a receiving roller 208 is arranged on the side of the transmission roller 6 207, and the receiving roller 208 is used for winding;

[0077] A material tightening roller 209 is provided between the transmission roller 5 206 and the transmission roller 6 207. Slide blocks are provided at both ends of the material tightening roller 209. A lifting groove 291 for the slide blocks to slide is provided inside the material discharging housing 103.

[0078] The anti-deviation component 003 includes a rotating roller 301. Baffles 302 are arranged on the outer sides of both ends of the rotating roller 301. Bearings 303 are arranged at both ends of the rotating roller 301. An installation block 304 is fixedly connected to the outer side of the bearing 303. The installation block 304 is installed on the support housing 001. An elliptical block 305 is arranged on the outer side of the rotating roller 301. The diameter at the center of the elliptical block 305 is larger than that at both ends.

[0079] During use, first place the flexible circuit board coil on the outer side of the feeding roller 201, then bypass the substrate around the first driving roller 202 and the anti-deviation component 003, pass through the cleaning component 100, then bypass over the second driving roller 203, the preliminary deviation correction component 004 and the third driving roller 204, pass through the first sensing component 006, enter the inside of the exposure housing 104 from the bottom of the fourth driving roller 205, then pass through the middle of the clamping and feeding mounting plate from above the fifth driving roller 206, and then bypass from the bottom of the tensioning roller 209, and wind it on the outer side of the take-up roller 208 through the sixth driving roller 207;

[0080] Among them, the anti-deviation component 003 is used for anti-deviation setting of the flexible circuit board. Since the elliptical block 305 is set with a larger diameter at the center than at both ends, according to the principle of centripetal force, it can make the flexible circuit board located in the middle of the elliptical block 305, thereby performing preliminary calibration on the flexible circuit board. The diameter difference between both ends and the middle of the elliptical block 305 is not large, preventing deformation damage to the substrate.

[0081] Among them, the first sensing component 006 includes an installation component 601. Square grooves 602 are opened at both ends inside the installation component 601. Detection frames 603 are slidably connected inside the square grooves 602. A strip-shaped groove 604 is opened at the inner bottom of the square groove 602.

When the width of the substrate is adjusted, the user can start the motor. The motor drives the lead screw to rotate. The thread directions at both ends of the lead screw are opposite, driving the sliders on both sides to move inward or outward simultaneously, and then driving the detection frame 603 to move, thereby adjusting the position of the fiber optic sensor and expanding the applicable range.

[0083] The preliminary deviation correction component 004 includes two symmetrically arranged installation boxes 401, a deviation correction roller 402 is arranged between the two installation boxes 401, both ends of the deviation correction roller 402 are fixedly connected with arc plates 403, the inner sides of the arc plates 403 are fixedly connected with arc blocks 404, an arc groove 405 is arranged on the inner side of the installation box 401, a rotating bead is arranged between the arc groove 405 and the arc block 404, and the arc block 404 and the arc groove 405 cooperate with each other;

[0084] A rotating groove 406 is fixedly connected to the outer side of the arc plate 403, a clamping groove 407 is provided inside the rotating groove 406, a rotating ball 408 is rotatably connected inside the rotating groove 406, a compensation rod 409 is fixedly connected to one end of the rotating ball 408, a correction block 410 is slidably connected to the outer side of the compensation rod 409, a limit block 411 is fixedly connected to the top of the correction block 410, the limit block 411 is slidably connected to the installation box 401, a hydraulic cylinder 412 is installed on the side of the installation box 401, and the output end of the hydraulic cylinder 412 is fixedly connected to the correction block 410;

[0085] The preliminary correction component 004 adjusts the angle of the correction roller 402 according to the signal received from the first sensing component 006.

Since the arc block 404 and the arc groove 405 are both arranged in an arc shape, the arc plate 403 can only move in an arc shape, so that the arc plate 403 pulls the rotating ball 408 to move, so that the compensation rod 409 slides inside the installation box 401, and then performs movable compensation. The arc blocks 404 on both sides of the correcting roller 402 have the same arc and the centers of the two arc blocks 404 coincide, so that the correcting roller 402 rotates, and then adjusts the position of the substrate on its top. The arc groove 405 is provided with a rotating ball to reduce friction, which is beneficial to the operation of the device.
