Description

Technical Field

[0001] The utility model relates to the field of bending devices, and specifically to an FPC circuit board bending device. Background Technique

[0002] An FPC circuit board, i.e., a flexible printed circuit board, has the characteristics of being bendable and foldable, and can adapt to the internal space layout of various complex electronic devices. Compared with traditional rigid circuit boards, FPC circuit boards are thinner and lighter, which is conducive to the miniaturization and lightweight design of electronic products. They are widely used in electronic products such as mobile phones, tablet computers, digital cameras, etc., providing key support for the high performance and reliable operation of electronic devices.

[0003] An FPC circuit board bending device is a device specifically used for bending flexible printed circuit boards. It can accurately control the bending angle and force, ensuring the quality and stability of the FPC circuit board after bending. In the production and processing process of FPC circuit boards, this bending device plays an important role, improving production efficiency and product quality.

[0004] When an FPC circuit board bending device is usually used, the two ends of the FPC circuit board are fixed and then bent by the bending device. During the bending process, the two ends of the circuit board will be pulled and thus separated from the clamping device, resulting in a reduction in bending quality.

[0005] Therefore, an FPC circuit board bending device is proposed to solve the above problems. Content of the Utility Model

When the pressing plate bends the circuit board, the position movement of the two ends of the circuit board during the clamping between the second slider and the fixing plate can be reduced. At the same time, after the first slider is moved down after the bending is completed, the elastic force of the first spring will push the second slider to release the clamping of the circuit board, so that the circuit board can be easily taken out, reducing the time for adjusting the second slider.

[0008] Preferably, a plurality of first round holes are formed in the pressing groove; a collection box is slidably connected to the bottom of the box body; a plurality of second round holes are formed in the top of the collection box; the first round holes and the second round holes are correspondingly arranged; a vacuum cleaner is fixedly connected to the middle of the collection box; by using the airflow generated by the vacuum cleaner to drain the debris, the storage time of the debris in the pressing groove can be reduced, and at the same time, the debris can be concentrated and collected inside the collection box. After the debris on the pressing groove is reduced, the damage of the circuit board during the bending work in the pressing groove can be reduced.

[0009] Preferably, a plurality of rollers are rotatably connected to the bottom of the box body; the rollers are located between the collection box and the box body; by using the rollers to assist in taking out the collection box, when the debris in the collection box accumulates too much, it can be easily taken out, reducing the contact area between the collection box and the box body, thereby improving the smoothness.

[0010] Preferably, an arc-shaped plate is fixedly connected to the top of the collection box; a plurality of third round holes are formed in the arc-shaped plate; the third round holes are correspondingly arranged with the first round holes and the second round holes; by installing the arc-shaped plate on the collection box, the vacuum cleaner can be protected.

At the same time, after the fixing block contacts the circuit board, it can also reduce the impact force of the second slider on the circuit board, thereby reducing the damage to the circuit board during fixing.

[0012] Preferably, a rubber pad is fixedly connected to the bottom of the fixing block; the rubber pad is provided with pores; by adding the rubber pad to increase the contact area with the surface of the circuit board, the stability of the second slider fixing the circuit board can be increased.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] The following gives specific embodiments.

[0025] Such as Figures 1 to 5As shown in the figure, a bending device for an FPC circuit board according to an embodiment of the present utility model includes a box body 1, and a maintenance door 12 is hinged in the middle of the box body 1; a cylinder 11 is fixedly connected to the top of the box body 1; a pair of electric push rods 13 are fixedly connected to the side wall of the box body 1; a first slider 14 is fixedly connected to the end of the electric push rod 13; the first slider 14 is slidably connected to the outer side wall of the box body 1; a pulling rope 15 is fixedly connected to the bottom of the first slider 14; the pulling rope 15 is arranged to penetrate through the box body 1 and is slidably connected; a second slider 17 is fixedly connected to the end of the pulling rope 15; the second slider 17 is slidably connected to the inner side wall of the box body 1; a first spring 16 is fixedly connected to the bottom of the box body 1; a fixing plate 101 is fixedly connected to the middle of the box body 1; the first spring 16 is arranged to penetrate through the fixing plate 101 and is slidably connected; a sliding rod 18 is slidably connected to the bottom of the cylinder 11; a pressing plate 19 is fixedly connected to the bottom of the sliding rod 18; a pressing groove 102 is formed in the middle of the fixing plate 101; the pressing plate 19 and the pressing groove 102 are correspondingly arranged and are slidably matched; during operation, first open the maintenance door 12, then start the electric push rods 13 on both sides to extend, push the first slider 14 to move downward. When the first slider 14 moves downward, the pulling rope 15 will move into the box body 1. At this time, the pressure of the first spring 16 will be released, thereby pushing the second slider 17 to move upward. When the upward movement of the second slider 17 stops, place the end of the circuit board between the fixing plate 101 and the second slider 17. After placing the circuit board, start the electric push rod 13 again to make the first slider 14 move upward, thereby tightening the pulling rope 15. When the pulling rope 15 is tightened, it will drive the second slider 17 to move downward, and at the same time, the first spring 16 will deform. When the bottom of the second slider 17 contacts the surface of the fixing plate 101, the first slider 14 stops moving upward. At this time, the circuit board is clamped by extrusion. Then start the cylinder 11 to push the sliding rod 18 to lower the pressing plate 19 to cooperate with the pressing groove 102 to bend the circuit board; by using the electric push rod 13 to push the first slider 14 to tighten the pulling rope 15 to clamp the circuit board by extrusion, the pulling rope 15 can be kept in a taut state all the time, thereby fixing the second slider 17. When the pressing plate 19 bends the circuit board, the position movement of the two ends of the circuit board during the clamping between the second slider 17 and the fixing plate 101 is reduced. At the same time, after the bending is completed, when the first slider 14 moves downward, due to the elastic force of the first spring 16, the second slider 17 will be pushed to contact and clamp the circuit board, so that the circuit board can be easily taken out, reducing the time for adjusting the second slider 17.

[0026] As Figures 2 to 4As shown, a plurality of first round holes 2 are formed inside the pressing groove 102; a collecting box 21 is slidably connected to the bottom of the box body 1; a plurality of second round holes 22 are formed in the top of the collecting box 21; the first round holes 2 and the second round holes 22 are arranged in correspondence; a dust collector 23 is fixedly connected to the middle of the collecting box 21; during operation, when the pressing plate 19 bends the circuit board, some debris will fall off the surface of the circuit board. At this time, the dust collector 23 is started, and then these debris will flow from the first round holes 2 to the second round holes 22 due to the adsorption air flow generated by the dust collector 23 and finally enter the inside of the collecting box 21. When it is necessary to clean the debris inside the collecting box 21, the maintenance door 12 can be opened, and then the collecting box 21 can be pulled out to clean the debris inside; by using the air flow generated by the dust collector 23 to drain the debris, the storage time of the debris in the pressing groove 102 can be reduced, and at the same time, the debris can be centrally collected into the collecting box 21. After the debris on the pressing groove 102 is reduced, the damage to the circuit board during the bending operation inside the pressing groove 102 can be reduced.

[0027] As Figure 5 shown, a plurality of rollers 3 are rotatably connected to the bottom of the box body 1; the rollers 3 are located between the collecting box 21 and the box body 1; during operation, since the debris generated when the circuit board is bent will be sucked into the collecting box 21 by the dust collector 23, when it is necessary to clean the debris inside the collecting box 21, the maintenance door 12 can be opened and then the collecting box 21 can be pulled out. When the collecting box 21 slides, the rollers 3 will roll to assist the sliding of the collecting box 21, so as to easily take out the collecting box 21; by using the rollers 3 to assist in taking out the collecting box 21, it can be easily taken out when the debris accumulates too much inside the collecting box 21, and the contact area between the collecting box 21 and the box body 1 can be reduced, thereby improving the smoothness.

[0028] As Figures 3 to 5 shown, an arc-shaped plate 4 is fixedly connected to the top of the collecting box 21; a plurality of third round holes 41 are formed inside the arc-shaped plate 4; the third round holes 41 are arranged in correspondence with the first round holes 2 and the second round holes 22; during operation, when the dust collector 23 sucks the debris, the debris will flow out of the first round holes 2, then pass through the third round holes 41, and then enter the inside of the collecting box 21 through the second round holes 22. At this time, the suction air flow generated by the dust collector 23 will suck some debris into its own interior; by installing the arc-shaped plate 4 on the collecting box 21, the dust collector 23 can be protected. By blocking the arc-shaped plate 4, the debris can be reduced from entering the inside of the dust collector 23, thereby increasing the service life of the dust collector 23.

[0029] As Figures 2 to 4As shown, a chute 52 is formed at the bottom of the second slider 17; a second spring 5 is fixedly connected inside the chute 52; the end of the second spring 5 is fixedly connected with a fixed block 51; the fixed block 51 is in sliding fit with the chute 52; during operation, when the second slider 17 fixes the end of the circuit board, the fixed block 51 will first contact the fixed block 51, and then the second spring 5 will be compressed and deformed to continuously hold the fixed block 51, so that the fixed block 51 closely adheres to the surface of the circuit board. When the second slider 17 touches the surface of the circuit board, the fixed block 51 and the second spring 5 will enter the inside of the chute 52 together; by using the cooperation of the fixed block 51 and the second spring 5, the circuit board can be pre-fixed before the second slider 17 contacts the circuit board, so as to be further fixed after the second slider 17 contacts the circuit board. At the same time, the fixed block 51 can also reduce the impact force of the second slider 17 on the circuit board after contacting the circuit board, thereby reducing the damage to the circuit board during fixation.

[0030] As Figures 2 to 4 shown, a rubber pad 6 is fixedly connected to the bottom of the fixed block 51; the rubber pad 6 is provided with pores; during operation, the rubber pad 6 will first contact the circuit board before the fixed block 51 contacts the circuit board. When the second slider 17 continues to be lowered, a pressure will be generated on the rubber pad 6. When the rubber pad 6 is compressed, the air inside will be discharged through the holes on the surface, so as to deform; by installing the rubber pad 6 to increase the contact area with the surface of the circuit board, the stability of the second slider 17 fixing the circuit board can be increased. When the second slider 17 touches the surface of the circuit board, it can enter the chute 52 together with the fixed block 51, reducing the influence on the second slider 17 fixing the circuit board.

[0031] Working principle: First, open the maintenance door 12, then start the electric push rods 13 on both sides to extend, pushing the first slider 14 downward. When the first slider 14 moves downward, the pulling rope 15 will move into the box body 1. At this time, the pressure of the first spring 16 will be released, thus pushing the second slider 17 upward. When the upward movement of the second slider 17 stops, place the end of the circuit board between the fixed plate 101 and the second slider 17. After placing the circuit board, start the electric push rod 13 again to move the first slider 14 upward, thereby tightening the pulling rope 15. When the pulling rope 15 is tightened, it will drive the second slider 17 downward, and at the same time, the first spring 16 will deform. When the bottom of the second slider 17 contacts the surface of the fixed plate 101, the upward movement of the first slider 14 stops. At this time, the circuit board is clamped by extrusion. Then start the cylinder 11 to push the sliding rod 18 to lower the pressing plate 19 to cooperate with the pressing groove 102 to bend the circuit board; when the pressing plate 19 bends the circuit board, some debris will fall off the surface of the circuit board. At this time, start the vacuum cleaner 23, and then these debris will flow from the first round hole 2 to the second round hole 22 and finally enter the inside of the collection box 21 due to the adsorption airflow generated by the vacuum cleaner 23. When it is necessary to clean the debris inside the collection box 21, the maintenance door 12 can be opened, and then the collection box 21 can be pulled out to clean the internal debris; since the debris generated when the circuit board is bent will be sucked into the collection box 21 by the vacuum cleaner 23, when it is necessary to clean the debris inside the collection box 21, the maintenance door 12 can be opened and then the collection box 21 can be pulled out. When the collection box 21 slides, the rollers 3 will roll to assist the sliding of the collection box 21, so that the collection box 21 can be taken out for cleaning; when the vacuum cleaner 23 sucks the debris, after the debris flows out of the first round hole 2, it will pass through the third round hole 41 and then enter the collection box 21 through the second round hole 22. At this time, the suction airflow generated by the vacuum cleaner 23 will suck some debris into itself; when the second slider 17 fixes the end of the circuit board, the fixing block 51 will first contact the fixing block 51, and then the second spring 5 will be compressed and deformed to always hold the fixing block 51, so that the fixing block 51 is closely attached to the surface of the circuit board. When the second slider 17 contacts the surface of the circuit board, the fixing block 51 and the second spring 5 will enter the chute 52 together; before the fixing block 51 contacts the circuit board, the rubber pad 6 will first contact the circuit board. When the second slider 17 continues to be lowered, it will exert pressure on the rubber pad 6. When the rubber pad 6 is squeezed, the air inside it will be discharged through the holes on the surface, thus deforming.

[0032] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
