Description

Technical Field

[0001] The present invention relates to the technical field of conductive adhesive coating, and specifically relates to a fully automatic roll-type conductive adhesive coating device. Background Art

[0002] A flexible printed circuit board, also known as an "FPC flexible board", is a printed circuit made of a flexible insulating substrate. It is a printed circuit board made of polyimide or polyester film as the substrate, with high reliability and excellent flexibility. During the manufacturing process of a flexible printed circuit board, when the circuits formed by electro-deposition or plating need to be electrically connected to each other, generally, two circuits are connected by a conductive adhesive.

[0003] For the method of connecting two circuits of a flexible printed circuit board by a conductive adhesive, generally, a conductive adhesive coating device is used to apply the conductive adhesive between the two circuits. Most of the existing automated conductive adhesive coating devices are equipped with an X-axis movement mechanism and a Y-axis movement mechanism to drive the roll mechanism of the conductive adhesive to move on a plane. Then, a laser cutting mechanism is set to cut the length of the required conductive adhesive. Through a vision detection mechanism, the direct distance between the two circuits is detected. Then, the roll mechanism of the conductive adhesive is controlled to move to the laser cutting mechanism to cut the conductive adhesive. The conductive adhesive is pasted on the release paper, and the laser only cuts the conductive adhesive. Then, the roll mechanism of the conductive adhesive is controlled to move to the position corresponding to the flexible circuit board again. The rectangular push block is pushed by a lifting cylinder to press the cut conductive adhesive to achieve automatic coating.

[0004] However, the above method of moving back and forth for laser cutting and pressing to coat the conductive adhesive requires separate cutting for each coating, which takes time for the laser to start and stop. Moreover, only by the single pressing coating method, it is easy to cause tape deviation or uneven force, and at the same time, it is impossible to automatically adjust the force and coating operation of the coated conductive adhesive according to the required length and thickness of the conductive adhesive.

[0016] The winding mechanism is composed of an electric winding roller, a guide roller, and a platform. One end of the flexible circuit board is connected to the electric winding roller. By starting the electric winding roller to start winding, it drives the flexible circuit board to move evenly on the platform.

A rectangular groove is opened on the inclined guide plate. The end of the push rod slides in the rectangular groove.

[0020] When it is necessary to adjust the distance between the first guide plate and the second guide plate, by starting the corresponding position adjustment mechanism, the moving block is driven to move, so that the second guide plate slides inside the first guide plate. At the same time, the push rod drives the inclined guide plate to rotate around the fixed shaft, synchronously changing the inclination angle of the fixed shaft.

[0021] Further, a bracket is fixedly connected to the left side of the bearing plate, and position adjustment mechanisms are fixedly connected to the back surface of the bearing plate and the lower side of the bracket. The position adjustment mechanism includes a housing, a first movable block, a third motor, and a second lead screw.

[0023] Start the laser cutting head, and at the same time start the position adjustment mechanism corresponding to the laser cutting head. The third motor drives the second lead screw to rotate. The second lead screw threadedly drives the first movable block to perform a linear motion inside the housing, thereby driving the laser cutting head to perform a linear motion, so that the laser cutting head performs laser cutting on the conductive adhesive on the first guide plate and the second guide plate. The cutting length is consistent with the distance between the two circuits being detected. The cut conductive adhesive is transported and moved to the central position below the guide block.

[0024] Further, the laminating adjustment mechanism includes a first track plate, a fourth motor, a bidirectional lead screw, a second movable block, and a clamping block. The output end of the lifting cylinder is fixedly connected with a first track plate. A fourth motor is fixedly connected to one end of the first track plate.

The outer side of the bidirectional lead screw is threadedly connected with two groups of second movable blocks. The lower side of the second movable block is fixedly connected with a clamping block.

[0025] According to the length of the cut conductive adhesive, start the fourth motor. The fourth motor drives the bidirectional lead screw to rotate. The bidirectional lead screw threadedly drives the two groups of second movable blocks to move closer to or away from each other synchronously, so that the distance between the two laminating adjustment mechanisms after movement is equal to the length of the cut conductive adhesive.

[0026] Further, the force adjustment mechanism includes a guiding housing, a connecting rod, a moving bracket, a moving rod, a magnetic block, a coil, and a fixed partition block.

[0027] According to the selected thickness of the conductive adhesive, control the current passed into the coil, so that the thicker the thickness of the conductive adhesive, the greater the current passed into the coil. After the coil is passed with current, a magnetic force attracting the magnetic block is generated, so that after the magnetic block is attached to the outer shell of the coil;

[0028] Further, the movement mechanism includes a connecting support plate, a third slider, a second track plate, a connecting frame, a first moving column, a first rotating plate, a second rotating plate, a second sliding block, a third track plate, and a second moving column.

[0029] Start the lifting cylinder. The lifting cylinder drives the covering adjustment mechanism, the force adjustment mechanism, and the movement mechanism to move downward synchronously. Then, after the conductive adhesive contacts the flexible circuit board, at this time, the two covering wheels are in contact with each other and are in the middle of the conductive adhesive section. During the continuous downward movement, the covering wheels are subjected to pressure. When the pressure breaks through the limitation of the attraction of the coil to the magnetic block, under the combined action of the first rotating plate, the second rotating plate, the third slider, the first moving column, the second sliding block, and the second moving column, the two covering wheels roll to both sides to perform a rolling press and covering on the lower conductive adhesive;

[0030] When the end of the conductive adhesive is pressed, due to the restriction and block of the clamping block, the covering wheel stops rolling outward, achieving the effect of fully pressing the conductive adhesive section. The conductive adhesive section separates from the release paper. After the visual inspection mechanism detects the covering quality, it then detects the covering length of the next conductive adhesive through the visual inspection mechanism again, and then the laser cutting head continuously performs laser cutting; the release paper separated from the conductive adhesive is wound and collected on the winding and guiding reel.

Through the two-way covering wheel and the two-way rolling covering method, it avoids the situations of tape deviation or uneven force in the existing operation and improves the covering quality.

[0034] 2. Through the cooperation among the covering adjustment mechanism, force adjustment mechanism, and motion mechanism, the present invention realizes that the movement stroke of the covering wheel can be controlled to match the length of the conductive adhesive to be cut, ensuring the accuracy of the length of the conductive adhesive rolled by the covering wheel, avoiding rolling too short or too long and affecting the covering quality. At the same time, it can automatically adjust the rolling force according to the thickness of the conductive adhesive, further improving the covering quality of the conductive adhesive.

When it is necessary to adjust the distance between the first guide plate and the second guide plate in the present invention, by starting the corresponding position adjustment mechanism, the moving block is driven to move, so that the second guide plate slides inside the first guide plate.

[0078] Start the lifting cylinder 75. The lifting cylinder 75 drives the laminating adjustment mechanism 9, the force adjustment mechanism 10, and the motion mechanism 11 to move downward synchronously. Then, after the conductive adhesive contacts the flexible circuit board, at this time, the two laminating wheels 762 are in contact with each other at the middle of the conductive adhesive section. During the continuous downward movement, the laminating wheels 762 are subjected to pressure. When the pressure breaks through the limitation of the attraction force of the coil 1006 on the magnetic block 1005, under the combined action of the first rotating plate 1106, the second rotating plate 1107, the third slider 1102, the first moving column 1105, the second sliding block 1108, and the second moving column 1110, the two laminating wheels 762 roll to both sides to perform a rolling press lamination on the lower conductive adhesive;

[0079] When pressing to the end of the conductive adhesive, due to the restriction and block of the clamping block 95, the covering wheel 762 no longer rolls outward, achieving the effect of fully pressing the conductive adhesive section. The conductive adhesive section separates from the release paper. After the visual inspection mechanism 74 detects the covering quality, it then detects the covering length of the next conductive adhesive again through the visual inspection mechanism 74, and then the laser cutting head 72 continuously performs laser cutting; the release paper separated from the conductive adhesive is wound onto the winding and guiding reel 713.

[0080] The specific usage method and function of this embodiment:

[0081] During use, the winding mechanism 2 is composed of an electric winding roller, a guiding roller, and a platform. One end of the flexible circuit board is connected to the electric winding roller, and the electric winding roller is started to drive the flexible circuit board to move at a uniform speed on the platform. Then, the composite integrated roll of release paper and conductive adhesive is equipped on the unwinding reel 711, and one end of it passes through the third guide wheel 731, the first guide plate 732, the second guide plate 737, the fourth guide wheel 733, the inclined guide plate 735, the guide block 761, the second guide wheel 718, the second feeding wheel 717, the first feeding wheel 715, and the first guide wheel 714 in sequence, and finally is connected to the winding reel 713;

[0082] Since the second feeding wheel 717 and the first feeding wheel 715 are electric feeding wheels, by starting the second feeding wheel 717, the first feeding wheel 715, and the winding reel 713, the release paper and the conductive adhesive are transported from the unwinding reel 711 to the winding reel 713.

[0083] Since the X-axis moving mechanism 3 and the Y-axis moving mechanism 4 are composed of a motor, a lead screw, a moving block, a slider, and a guide rail, the motor drives the lead screw to rotate, and the lead screw thread drives the moving block to perform a linear movement. Then, under the action of the slider and the guide rail, the action mechanism 6 is driven to move on the plane, and further drives the visual inspection mechanism 74 to move to the corresponding position of the flexible circuit board, and the distance between the two circuits that need to be connected is detected through the visual inspection system;

[0084] Subsequently, the laser cutting head 72 is started, and at the same time, the position adjustment mechanism 8 corresponding to the laser cutting head 72 is started. The motor three 83 drives the lead screw two 84 to rotate, and the lead screw two 84 thread drives the movable block one 82 to perform a linear movement inside the housing 81, and further drives the laser cutting head 72 to perform a linear movement, so that the laser cutting head 72 performs laser cutting on the conductive adhesive on the first guide plate 732 and the second guide plate 737. The cutting length is consistent with the detected distance between the two circuits. After cutting, the conductive adhesive is transported and moved to the center position below the guide block 761;

[0085] By starting the first motor 61, the first motor 61 drives the rotating shaft 62 to rotate, so that the conductive adhesive is aligned with the applied circuit. Then, the second motor 631 is started, and the second motor 631 drives the first lead screw 632 to rotate. The first lead screw 632 drives the first moving block 634 to slide inside the lifting housing 633 through threads. Then, with the assistance of the second slider 635, the coating mechanism 7 is driven to descend, so that the guide block 761 moves to a position corresponding to the flexible circuit board;

[0086] According to the length of the cut conductive adhesive, the fourth motor 92 is started. The fourth motor 92 drives the bidirectional lead screw 93 to rotate. The bidirectional lead screw 93 drives two groups of second moving blocks 94 to move closer to or away from each other synchronously through threads, so that the distance between the two coating adjustment mechanisms 9 after movement is equal to the length of the cut conductive adhesive;

[0087] According to the selected thickness of the conductive adhesive, the current passed into the coil 1006 is controlled. The thicker the conductive adhesive, the greater the current passed into the coil 1006. After the coil 1006 is energized, a magnetic force field that attracts the magnetic block 1005 is generated, so that after the magnetic block 1005 is attached to the outer shell of the coil 1006;

[0088] The lifting cylinder 75 is started. The lifting cylinder 75 drives the coating adjustment mechanism 9, the force adjustment mechanism 10, and the movement mechanism 11 to move downward synchronously. Then, after the conductive adhesive contacts the flexible circuit board, at this time, the two coating wheels 762 are in contact with each other at the middle of the conductive adhesive section. During the continuous downward movement, the coating wheels 762 are subjected to pressure. When the pressure breaks through the limitation of the attraction of the coil 1006 to the magnetic block 1005, under the combined action of the first rotating plate 1106, the second rotating plate 1107, the third slider 1102, the first moving column 1105, the second sliding block 1108, and the second moving column 1110, the two coating wheels 762 roll to both sides to perform a rolling press coating on the lower conductive adhesive;

[0089] When pressing to the end of the conductive adhesive, due to the restriction and block of the clamp 95, the coating wheels 762 no longer roll outward, achieving the effect of completely pressing the conductive adhesive section. The conductive adhesive section is separated from the release paper. After the visual inspection mechanism 74 detects the coating quality, then the visual inspection mechanism 74 detects the coating length of the next conductive adhesive again, and then the laser cutting head 72 performs laser cutting continuously; the release paper separated from the conductive adhesive is wound onto the take-up reel 713;

[0090] A spring is installed on the tension adjustment wheel 716. By controlling the pre-tightening force of the spring, the tension during the conductive adhesive transportation is controlled.

[0091] When it is necessary to adjust the distance between the first guide plate 732 and the second guide plate 737, the corresponding position adjusting mechanism 8 is started, thereby driving the moving block 738 to move, so that the second guide plate 737 slides inside the first guide plate 732. At the same time, the push rod 734 drives the inclined guide plate 735 to rotate around the fixed shaft 736, and synchronously changes the inclination angle of the fixed shaft 736.
