Description

Technical Field

[0001] The present invention relates to the technical field of flexible circuit board processing, and in particular to flexible circuit board production equipment. Background Art

[0002] Mounting is a crucial step in the production of flexible circuits. Solder paste is first applied via screen printing, followed by component placement using a placement machine. Finally, the circuit is soldered and cooled in a reflow oven. It's important to ensure the flatness of flexible circuit boards as they move between machines to prevent warping that could affect processing quality.

[0003] To this end, Chinese patent publication No. CN118695496A proposes a placement device for flexible circuit board production. In the technical solution of this patent document, by setting a mirror flattening component above the conveyor belt, the moving flexible circuit board body with patch components attached can be flattened and sorted on the assembly line. This rolling flattening operation is performed directly on the conveyor belt. Since the flexible circuit board is often placed directly on the conveyor belt, the transportation between it and the conveyor belt is completely dependent on friction. During rolling flattening, the movement direction of the rolling flattening component and the conveying direction are both horizontal, which easily causes the flexible circuit board to slide together, resulting in unsatisfactory rolling flattening effect.

[0004] Therefore, it is necessary to provide a flexible circuit board production equipment to solve the above technical problems. Summary of the Invention

[0005] The object of the present invention is to provide a flexible circuit board production device to solve the existing problems in the above background technology.

[0008] The rolling device is composed of a supporting part, a fixing part and a rolling part, wherein the supporting part is used to stably support the lower side of the conveyor belt when the flexible circuit board is rolled, and the fixing part is arranged on the frame;

[0009] The fixing portion can fix the flexible circuit board by itself after being supported by the supporting portion, and the fixing portion is connected to the supporting portion through a connecting component.

[0012] As a further solution of the present invention, the connecting assembly includes an inverted wedge plate, two positive wedge plates and two connecting rods, one end of the connecting rod is fixedly connected to the positive wedge plate, and the other end of the connecting rod is fixedly set on the side wall of the limiting plate. The inverted wedge plate is fixedly set on the support plate, and the inverted wedge plate is set between the two positive wedge plates, and the two inclined surfaces of the inverted wedge plate are respectively slidably fitted with the two positive wedge plates.

[0013] As a further solution of the present invention, the rolling part is composed of a flexible rolling roller and two lifting brackets. The flexible rolling roller is arranged between the two lifting brackets, and the flexible rolling roller can move back and forth linearly in the horizontal direction of the lifting brackets.

[0014] As a further solution of the present invention, the lifting mechanism includes a left rack, a gear, a right rack and a connecting plate. The left rack and the right rack are both engaged with the gear, and the left rack and the right rack are symmetrically arranged along the axis of the gear. The lower end of the connecting plate is fixedly connected to the side wall of the inverted wedge plate, the left rack is fixed to the upper end of the connecting plate, and the right rack is fixedly connected to the lifting bracket.

[0016] As a further solution of the present invention, a position-limiting lifting rod is fixedly provided on the frame, and a lifting end of the position-limiting lifting rod is fixed on the lower side of the lifting bracket.

[0017] As a further solution of the present invention, two avoidance grooves are provided on the support plate, and the two avoidance grooves are symmetrically distributed along the horizontal center line of the support plate.

[0018] The present invention provides a rolling device composed of a supporting part, a fixing part and a rolling part. When the conveyor belt conveys the flexible circuit to the corresponding position, the supporting part quickly supports the bottom of the conveyor belt. At the same time, the fixing part automatically fixes the front and rear sides of the flexible circuit board. Then the rolling part rolls and flattens it, so that the flexible circuit board can always remain fixed during the rolling process, thereby ensuring the rolling effect. By providing a liftable supporting part, the lower side of the flexible circuit board can be supported during the rolling operation, so that the rolling part can effectively roll the flexible circuit board, and the support part is lifted after the rolling is completed. The lowering of the support plate can reduce the transportation resistance of the conveyor belt; by setting the connecting component, it can be achieved that after the support part is completed, the front and rear sides of the flexible circuit board can be clamped and fixed at the same time.

DETAILED DESCRIPTION

[0029] Example 1

[0030] Reference Figure 1 A flexible circuit board production device includes two support bases 1, two frames 25 are provided on the two support bases 1, two conveying rollers 2 are provided between the two frames 25, and a conveyor belt 3 is provided on the two conveying rollers 2. The conveyor belt 3 is used to convey a flexible circuit board 4, and the frame 25 is provided with a rolling device for rolling the flexible circuit board 4;

[0031] The rolling device consists of a supporting portion, two fixing portions and a rolling portion, wherein the supporting portion is used to stably support the lower side of the conveyor belt 3 when the flexible circuit board 4 is rolled, and the two fixing portions are respectively arranged on adjacent frames 25;

[0032] Reference Figure 4 The fixing part can fix the flexible circuit board 4 by itself after being supported by the supporting part. The fixing part is connected to the supporting part through a connecting component. The fixing part consists of a fixing bracket 5, two push rods 16, a fixing plate 15, two limit plates 14 and a spring 18. A limit groove 26 is provided on the fixing bracket 5. The two limit plates 14 are slidably set in the limit groove 26 and are connected by a spring 18. One end of the push rod 16 is rotatably connected to the adjacent limit plate 14, and the other end of the push rod 16 is rotatably connected to the fixing plate 15; the fixing bracket 5 is welded and fixed to the frame 25.

[0033] The rolling part can roll and flatten the flexible circuit board 4, and the rolling part is connected to the support part through a lifting mechanism. The lifting mechanism enables the rolling part to automatically descend to the rolling height after the support part completes the support.

[0034] The support part consists of a support plate 10 and multiple lifting cylinders 12. Each lifting cylinder 12 is symmetrically arranged along the center of the support plate 10. The bottom end of the lifting cylinder 12 is fixedly mounted on the frame 25, and the lifting end of the lifting cylinder 12 is fixed on the lower side of the support plate 10.

[0035] Reference Figure 3Two avoidance grooves 24 are provided on the support plate 10, and the two avoidance grooves 24 are symmetrically distributed along the horizontal center line of the support plate 10. By setting the avoidance grooves 24, when the support plate 10 moves up and down, there will be no movement interference with the fixed bracket 5.

[0036] In this embodiment, the flexible circuit boards 4 are placed on the conveyor belt 3 at equal intervals and are conveyed by the conveyor belt 3. When the rightmost flexible circuit board 4 is conveyed to the designated position, the conveyor belt 3 stops conveying, and the position of the flexible circuit board 4 remains unchanged.

[0037] Subsequently, the lifting cylinder 12 pushes the support plate 10 upward until the upper end surface of the support plate 10 contacts the inner side surface of the conveyor belt 3 to provide support for the flexible circuit board 4. During this process, the connecting assembly causes the fixing part to perform the following actions:

[0038] Reference Figure 3 and Figure 4 , the spring 18 contracts and can pull the two limit plates 14 to slide close in the limit groove 26, so that the push rod 16 can be deflected. When the two push rods 16 deflect, the fixed plate 15 connected to it is pushed outward, so that the fixed plate 15 moves toward the side away from the fixed bracket 5, along Figure 2 The direction shown is: the two fixing plates 15 are close to each other, at this time the flexible circuit board 4 between the two fixing plates 15 can be fixed, effectively preventing the flexible circuit board 4 from slipping during the rolling process, so as to ensure a good rolling effect. Figure 7 shown.

[0039] The lifting mechanism will also drive the rolling part to move down to the rolling height to perform rolling and flattening processing on the flexible circuit board 4.

[0040] Example 2

[0041] On the basis of Example 1, the connection assembly in this embodiment specifically includes an inverted wedge plate 13, two positive wedge plates 22 and two connecting rods 17. One end of the connecting rod 17 is fixedly connected to the positive wedge plate 22, and the other end of the connecting rod 17 is fixedly set on the side wall of the limit plate 14. The inverted wedge plate 13 is fixedly set on the support plate 10, and the inverted wedge plate 13 is set between the two positive wedge plates 22. The two inclined surfaces of the inverted wedge plate 13 are respectively slidably fitted with the two positive wedge plates 22.

[0042] The inverted wedge plate 13 is fixed to the support plate 10 and rises and falls synchronously with the support plate 10. When the support plate 10 rises, the inclined surfaces on both sides of the inverted wedge plate 13 push the positive wedge plate 22 toward the center. The positive wedge plate 22, via the connecting rod 17, drives the limit plate 14 to move within the limit slot 26 of the fixed bracket 5. At this time, one end of the push rod 16 moves with the limit plate 14, while the other end pushes the fixed plate 15 toward the edge of the flexible circuit board 4, completing the clamping action.

[0043] The inclined surfaces of the reverse wedge plate 13 and the positive wedge plate 22 cooperate to convert the vertical movement of the support plate 10 into the horizontal movement of the fixed plate 15, without the need for an additional power source, and the synchronous triggering of support and clamping is achieved only through mechanical transmission.

[0044] In this embodiment, when the support plate 10 moves upward as in the first embodiment, it will drive the inverted wedge plate 13 to move upward. Figure 6 When the inverted wedge plate 13 moves upward, the two positive wedge plates 22 on both sides thereof will gradually approach each other under the action of the inclined surface and the elastic force of the spring 18. In this way, the two positive wedge plates 22 will drive the two limit plates 14 to approach each other synchronously through the connecting rod 17, and the action of fixing the flexible circuit board 4 as described in the first embodiment can be performed.

[0045] After rolling and flattening, the support plate 10 moves downward to separate from the conveyor belt 3. It no longer contacts the inner side of the conveyor belt 3, reducing the conveying resistance of the conveyor belt 3. Furthermore, the support plate 10 drives the inverted wedge plate 13 downward. As the inverted wedge plate 13 moves downward, it forces the two positive wedge plates 22 to move away from each other. The positive wedge plate 22 also forces the two limit plates 14 to move away from each other via the connecting rod 17. As the two limit plates 14 move away from each other, they pull the push rod 16 in the opposite direction, causing it to deflect in the opposite direction. This pulls the fixing plate 15 back to its original position and simultaneously releases the flexible circuit board 4.

[0046] It should be noted that the fixing plates 15 on both sides move back synchronously to ensure that the circuit board is evenly stressed during the loosening process, maintains a flat posture, and provides a stable reference for subsequent transportation.

[0047] The connecting assembly utilizes a beveled structure consisting of an inverted wedge plate 13 and a positive wedge plate 22. As the support plate 10 rises, the inverted wedge plate 13 pushes the positive wedge plate 22 toward the center, which in turn drives the stop plate 14 toward the center via a connecting rod 17, ultimately allowing the fixing plate 15 to clamp the flexible circuit board 4. This eliminates the need for an additional power source, achieving automatic clamping solely through the lifting and lowering motion of the support plate 10. This reduces energy consumption and control complexity, making it suitable for synchronized operation on high-speed assembly lines. The fixing portion is connected to the stop plate 14 via a spring 18, providing a flexible cushion during the clamping process, preventing damage to the edges of the flexible circuit board 4 caused by rigid clamping.

[0048] When the support plate 10 moves downward and drives the inverted wedge plate 13 downward, the inclined surfaces on both sides of the inverted wedge plate 13 no longer excessively squeeze the positive wedge plate 22. The positive wedge plate slides outward under the action of the spring 18, and pulls the limit plate 14 to move in the opposite direction through the connecting rod 17. The push rod 16 rotates accordingly and drives the fixing plate 15 to release the circuit board.

[0049] In addition, when the support plate 10 moves downward, the relative sliding of the inverted wedge plate 13 and the positive wedge plate 22 can remove tin slag, dust and other debris between the inclined surfaces, and always keep the inverted wedge plate 13 and the positive wedge plate 22 sliding smoothly.

[0050] During its return, the retaining plate 15 slowly separates from the edge of the circuit board, preventing edge warping or copper foil tearing caused by rigid pulling. The synchronized movement of the two retaining plates ensures a smooth release process and a stable position for subsequent transport. The cushioning effect of the spring 18 reduces vibration during the return movement of the retaining plate 15, preventing SMD components from falling due to impact. The elastic reset mechanism requires no additional power, reducing equipment energy consumption and extending the service life of the retaining bracket 5 and push rod 16.

[0051] Furthermore, in this embodiment, the rolling part can be specifically composed of a flexible rolling roller 9 and two lifting brackets 11. The flexible rolling roller 9 is arranged between the two lifting brackets 11, and the flexible rolling roller 9 can move back and forth linearly along the horizontal direction of the lifting brackets 11.

[0052] Specifically, a linear drive component such as a horizontal air cylinder or a telescopic oil cylinder can be provided on the lifting bracket 11. Taking the air cylinder as an example, two telescopic air cylinders 28 are used in this embodiment. Rotating shafts 27 can be provided at both ends of the flexible rolling roller 9, and the rotating shafts 27 are rotatably connected to the flexible rolling roller 9, so that the flexible rolling roller 9 can rotate along its own axis. The telescopic portion of the telescopic air cylinder 28 is fixedly connected to the rotating shaft 27, so that the telescopic air cylinder 28 drives the flexible rolling roller 9 to perform linear reciprocating motion in the horizontal direction. Specifically, during application, a mounting plate 29 can be fixedly connected to one side of the two opposing inner walls of the lifting bracket 11, and the base of the telescopic air cylinder 28 is fixedly provided on the side wall of the mounting plate 29. In this way, when the telescopic air cylinder 28 is extended and retracted, the flexible rolling roller 9 can be driven to perform linear reciprocating motion along the lifting bracket 11 via the rotating shaft 27.

[0053] When the lifting mechanism drives the rolling part down to the rolling height, the flexible rolling roller 9 moves linearly along the horizontal direction of the lifting bracket 11. When the flexible rolling roller 9 contacts the flexible circuit board 4, the flexible rolling roller 9 will rotate and roll the flexible circuit board 4 to flatten it.

[0054] After the flexible rolling roller 9 is raised, it maintains a safe distance from the conveyor belt 3, and the flexible rolling roller 9 rubs against the running conveyor belt 3; the rising action is completed synchronously with the lowering of the support plate 10, ensuring that the production line is connected without pause and improving continuous production efficiency.

[0055] Example 3

[0056] On the basis of Example 1 and Example 2, the lifting mechanism in this embodiment includes a left rack 21, a gear 20, a right rack 19 and a connecting plate 23. The left rack 21 and the right rack 19 are both engaged with the gear 20, and the left rack 21 and the right rack 19 are symmetrically arranged along the axis of the gear 20. The lower end of the connecting plate 23 is fixedly connected to the side wall of the inverted wedge plate 13, the left rack 21 is fixed to the upper end of the connecting plate 23, and the right rack 19 is fixedly connected to the lifting bracket 11.

[0057] The left rack 21 is fixed to a connecting plate 23, which is connected to the inverted wedge plate 13 and rises and falls with the support plate 10. When the support plate 10 rises, the left rack 21 moves upward, driving the gear 20 to rotate. The gear 20 then drives the right rack 19 downward. The right rack 19 is fixed to the lifting bracket 11, thereby synchronously descending the flexible rolling roller 9 to the rolling height. Conversely, when the support plate 10 descends, the various components move in the opposite direction, causing the rolling roller 9 to return to its original position.

[0058] The meshing transmission of the gear rack synchronously transmits the vertical movement of the support plate 10 to the rolling roller 9, ensuring that the movement heights of the two are consistent, avoiding uneven pressure due to height deviation during rolling. At the same time, the smoothness of the gear transmission ensures the uniform speed of the rolling roller 9 during the descent process.

[0059] A limit lifting rod 6 is fixed on the frame 25, and the lifting end of the limit lifting rod 6 is fixed to the lower side of the lifting bracket 11. Figure 1 As shown, by providing the limiting lifting rod 6, not only can the right side of the lifting bracket 11 be supported to keep it stable, but also when the lifting bracket 11 moves in the vertical direction, the limiting lifting rod 6 can also be raised and lowered accordingly, so that the movement of the lifting bracket 11 is more stable.

[0060] Furthermore, the guiding function of the limiting lifting rod 6 ensures the vertical movement of the lifting bracket 11, so that the flexible rolling roller 9 always remains parallel to the surface of the circuit board, avoiding local overpressure or insufficient pressing due to tilting, and at the same time enhancing the stability of the rolling process.

[0061] The side wall of the frame 25 is fixedly connected to a support rod 7, and one end of the support rod 7 away from the frame 25 is fixedly connected to a protective shell 8, and the lifting mechanism is arranged in the protective shell 8. Figure 2 Specifically, the right side of the protective shell 8 is open to facilitate the up and down movement of the lifting bracket 11. Figure 3 The connecting plate 23 slides through the lower side of the protective shell 8 and can slide freely up and down. The left rack 21 and the right rack 19 are both slidably set in the protective shell 8, and the gear 20 is rotatably set on the inner wall of the protective shell 8.

[0062] In this embodiment, when the support plate 10 moves upward, the support plate 10 will drive the inverted wedge plate 13 and the connecting plate 23 to rise synchronously. At this time, the connecting plate 23 will drive the left rack 21 to move upward. Figure 5 As shown, when the left rack 21 moves up, the gear 20 can rotate clockwise, and when the gear 20 rotates clockwise, it will drive the right rack 19 to move down, and the right rack 19 will drive the lifting bracket 11 to move down, and the flexible rolling roller 9 set on the lifting bracket 11 will also move down to the rolling height. After the rolling is completed, when the support plate 10 moves down, the various components will move in the opposite direction, and finally the lifting bracket 11 and the flexible rolling roller 9 can be moved up and reset.

[0063] In combination with Examples 1 to 3, the supporting, clamping, and rolling actions are uniformly driven by the lifting and lowering of the support plate 10, and the movement timing of each component is closely connected to form a continuous automated process, which reduces the waiting time of step-by-step operations in traditional equipment and improves production efficiency.
