Description

Technical Field

[0001] This utility model relates to a positioning device, and more particularly to a flexible circuit board positioning device. Background Technology

[0002] Flexible circuit boards, also known as "flexible boards," are printed circuit boards made with polyimide or polyester film as the substrate. They are highly reliable and extremely flexible, characterized by high wiring density, light weight, and thinness. They can be freely bent, rolled, and folded, and can withstand millions of dynamic bends without damaging the wires. Their size can be arbitrarily designed according to spatial layout requirements, and they can move and stretch freely in three-dimensional space, thereby achieving the integration of component assembly and wire connection. They are mainly used in various electronic products. Therefore, flexible circuit boards have been widely used in communication equipment, smartphones, computers, medical equipment, automotive electronics, aerospace and military equipment and other fields.

[0003] However, due to the flexibility of flexible circuit boards, they are easily affected by external factors during production and subsequent processing, resulting in deformation or bending. This leads to errors in production and subsequent processing, reduces processing accuracy, and hinders efficient operation. To address these issues, a solution is proposed: the design of a flexible circuit board positioning device. Utility Model Content

[0004] In order to overcome the disadvantage that flexible circuit boards are prone to deformation or bending during production and subsequent processing, the technical problem of this utility model is to provide a flexible circuit board positioning device.

[0005] A flexible circuit board positioning device includes a placement plate, a mounting component, a first electric slide rail, a second electric slide rail, and a fixing rod. A set of second electric slide rails is provided in both length directions of the placement plate. The slider of the second electric slide rail is connected to the slider of the first electric slide rail. The mounting component is fixedly connected to the side of the first electric slide rail facing away from the second electric slide rail. The fixing rod is movably connected to the mounting component. The first electric slide rail and the second electric slide rail intersect perpendicularly. The fixing rod is used to limit the flexible circuit board.

[0006] Optionally, the bottom of the placement plate is equipped with pulleys via a connecting rod.

[0007] Optionally, a clamping plate is movably connected to one side of the placement plate in the width direction, and a threaded rod is threadedly connected to the bottom of the clamping plate.

[0008] Optionally, a set of support plates is fixedly connected to the other side of the width direction of the placement plate. The two support plates are slidably connected to the first guide rods respectively. The ends of the two first guide rods away from the clamping plate are fixedly connected to the handles. The ends of the two first guide rods away from the handles are fixedly connected to the mounting plate. The mounting plate is slidably connected to the pressure rollers through the opened grooves.

[0009] Optionally, a second guide rod is fixedly connected to the groove of the mounting plate. The second guide rod slides through the pressure roller, and a spring is wound around the second guide rod. The two ends of the spring are connected to the mounting plate and the pressure roller, respectively.

[0010] Optionally, the placement plate is provided with a set of wedge blocks fixedly connected in the width direction of the clamping plate. The wedge blocks have a V-shaped structure. When the pressure roller contacts the inclined surface of the wedge block, the pressure roller is squeezed by the wedge block and rolls upward.

[0011] The beneficial effects of this utility model are as follows: 1. By using the combination of the first electric slide rail and the second electric slide rail, the mounting component can move arbitrarily within a large range, thereby accurately positioning the positioning hole of the flexible circuit board, which helps to reduce positioning errors and improve processing accuracy.

[0012] 2. The V-shaped structure design of the wedge block allows the pressure roller to slide upwards through the squeezing action of the inclined surface when it comes into contact with the wedge block, thereby avoiding pushing the clamping plate and causing it to fall off or damage the flexible circuit board. The restoring force of the spring allows the pressure roller to quickly return to its original position after disengaging from the wedge block and continue to work, improving the reliability and stability of the device.

[0013] 3. By pulling the handle outward, the position of the pressure roller can be easily adjusted so that it can contact and stretch the flexible circuit board. The threaded rod design allows the clamp to firmly fix the flexible circuit board, preventing displacement or deformation during subsequent operations. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] Example: A flexible circuit board positioning device, such as Figure 1 , Figure 2 and Figure 5 As shown, the device includes a placement plate 2, a mounting component 3, a first electric slide rail 301, a second electric slide rail 302, and a fixing rod 303. A set of second electric slide rails 302 is provided in both length directions of the placement plate 2. The slider of the second electric slide rail 302 is connected to the slider of the first electric slide rail 301. The mounting component 3 is fixedly connected to the side of the first electric slide rail 301 facing away from the second electric slide rail 302. The fixing rod 303 is movably connected to the mounting component 3. The first electric slide rail 301 and the second electric slide rail 302 intersect perpendicularly. The fixing rod 303 is used to limit the flexible circuit board. Here, depending on the different hole diameters of the positioning holes on the flexible circuit board, the original fixing rod 303 can be removed and replaced with a fixing rod 303 of a model that matches the hole diameter, thereby increasing the flexibility of the device.

[0022] like Figure 1 and Figure 2 As shown, a pulley 1 is installed at the bottom of the corner of the placement plate 2 via a connecting rod. Here, the device can be moved to the required position via the pulley, which facilitates subsequent work.

[0023] like Figure 3 and Figure 4 As shown, a clamping plate 6 is movably connected to one side of the placement plate 2 in the width direction. A threaded rod 601 is threadedly connected to the bottom of the clamping plate 6. Here, by rotating the threaded rod 601 counterclockwise, the threaded rod 601 is screwed inward until it contacts the placement plate 2. After that, the threaded rod 601 is restricted by the placement plate 2 and no longer screws inward. At this time, the clamping plate 6 has less room to move due to the screwing in of the threaded rod 601, thus fixing the clamping plate 6 to the placement plate 2.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, a set of support plates 401 are fixedly connected to the other side of the width direction of the placement plate 2. Two support plates 401 are slidably connected to first guide rods 402. A handle 4 is fixedly connected to the ends of the two first guide rods 402 away from the clamping plate 6. A mounting plate 501 is fixedly connected to the ends of the two first guide rods 402 away from the handle 4. A pressure roller 5 is slidably connected to the mounting plate 501 through a groove. A second guide rod 502 is fixedly connected to the groove in the mounting plate 501. The second guide rod 502 slides through the pressure roller 5. A spring 503 is wound around the second guide rod 502. The two ends of the spring 503 are respectively connected to the mounting plate 501. Connected to the pressure roller 5, the placement plate 2 is provided with a set of wedge blocks 504 fixedly connected in the width direction of the clamping plate 6. The wedge blocks 504 have a V-shaped structure. Here, the V-shaped structure design of the wedge blocks 504 allows the wedge blocks 504 to squeeze the pressure roller 5 and make it slide upward when the pressure roller 5 contacts the inclined surface of the wedge blocks 504. At this time, the spring 503 is compressed, and the pressure roller 5 moves obliquely upward, so that the pressure roller 5 no longer pushes the clamping plate 6 when it rolls, effectively preventing the clamping plate 6 from falling off and the flexible circuit board from being damaged. When the pressure roller 5 is separated from the wedge blocks 504, the spring 503 returns to its initial state and drives the pressure roller 5 to move downward, so that the pressure roller 5 can continue to work.

[0025] This device can be used when it is necessary to position the flexible circuit board to facilitate subsequent work. First, pull the handle 4 outward. The handle 4 drives the first guide rod 402 to slide outward. The first guide rod 402 drives the mounting plate 501 to move, which in turn drives the pressure roller 5 to roll towards the support plate 401. Then, the flexible circuit board is placed on the placement plate 2. By tightening the screw rod 601, the screw rod 601 is screwed inward until it abuts against the placement plate 2. After that, the screw rod 601 is restricted by the placement plate 2 and no longer screws inward, thus fixing the clamping plate 6 to the placement plate 2, thereby fixing the flexible circuit board in place. Then, push the handle 4 inward. The handle 4 drives the first guide rod 402 to slide inward. The first guide rod 402 drives the mounting plate 501 to move, which in turn drives the pressure roller 5 to roll towards the clamping plate 6. The pressure roller 5 squeezes the flexible circuit board. After repeating the push and pull action multiple times, the pressure roller 5 stretches the flexible circuit board and prevents it from bending. After the flexible circuit board is stretched and fixed, the first electric slide rail 301 and the second electric slide rail 302 are activated successively. The slider of the second electric slide rail 302 drives the first electric slide rail 301 to slide left and right, and the first electric slide rail 301 drives the mounting component 3 to slide forward and backward, so that the mounting component 3 can move arbitrarily within the range of motion of the first electric slide rail 301 and the second electric slide rail 302, thereby accurately positioning the positioning hole of the flexible circuit board. When the mounting component 3 positions the positioning hole of the flexible circuit board, a fixing rod 303 is placed on the mounting component 3. The fixing rod 303 passes through the through hole of the mounting component 3 and engages with the positioning hole of the flexible circuit board, thereby fixing the flexible circuit board and preventing the flexible circuit board from deforming in subsequent operations.
