Description

Technical Field

[0001] This application relates to the field of flexible circuit boards, and more particularly to an auxiliary tool for attaching FPC reinforcing plates. Background Technology

[0002] Flexible printed circuit boards (FPCs) are widely used in consumer electronics, automotive electronics, and other fields due to their lightweight and bendable properties. In the FPC manufacturing process, the bonding of reinforcing plates is a key step, used to enhance the mechanical strength of localized areas. Current methods require placing the FPC on a workbench, then placing the reinforcing plate in its corresponding position on the FPC for bonding. This necessitates repeated adjustments to the reinforcing plate's position during bonding, affecting both positioning accuracy and bonding efficiency. Utility Model Content

[0003] To improve bonding efficiency, this application provides an auxiliary tool for bonding FPC reinforcing plates.

[0004] This application provides an FPC reinforcing plate pasting auxiliary tool, which adopts the following technical solution:

[0005] An auxiliary tool for attaching an FPC reinforcing plate includes a first clamping plate and a second clamping plate, which are hinged together. The first clamping plate is provided with a positioning element for positioning the circuit board, and the second clamping plate is provided with a positioning groove. When the circuit board is mounted on the first clamping plate, the position of the positioning groove corresponds to the position on the first clamping plate where the reinforcing plate needs to be installed.

[0006] By adopting the above technical solution, a first clamping plate and a second clamping plate are provided. When it is necessary to attach the reinforcing plate, the flexible circuit board is first installed on the first clamping plate through the positioning component. The flexible circuit board is clamped by the first clamping plate and the second clamping plate, and the reinforcing plate is placed in the positioning groove. The positioning groove is used to position the reinforcing plate, so that the reinforcing plate is attached to the flexible circuit board, which improves both the accuracy and efficiency of the attachment.

[0007] Optionally, the positioning elements are provided in several groups, and the several groups of positioning elements are distributed along the width direction of the first clamping plate. The positioning grooves are provided in several ways and correspond one-to-one with the several groups of positioning elements.

[0008] By adopting the above technical solution, the positioning components are set in several groups, which can simultaneously install several flexible circuit boards on the first clamping plate, thereby further improving the bonding efficiency.

[0009] Optionally, a heating platform is provided on the side of the first clamping plate away from the second clamping plate.

[0010] By adopting the above technical solution and setting up a heating platform, the curing speed of the adhesive can be accelerated and the bonding stability can be improved.

[0011] Optionally, the second clamping plate is provided with a locking component, and the first clamping plate is provided with a locking hole for the locking component to lock in place.

[0012] By adopting the above technical solution, a locking component is provided, which is locked in the locking hole, thereby fixing the first clamping plate and the second clamping plate and improving the stability of circuit board installation.

[0013] Optionally, the locking element is hemispherical, and the plane of the locking element is fixed to the side of the second clamping plate near the first clamping plate.

[0014] By adopting the above technical solution, since the second clamping plate rotates relative to the first clamping plate, the locking member is set as a hemispherical shape, making it easier for the locking member to be locked in the locking hole.

[0015] Optionally, the first clamping plate is provided with a limiting boss, which slides along the length of the first clamping plate and is connected to the first clamping plate. The limiting boss can protrude from the inner wall of the locking hole, and the locking member has an annular groove for the limiting boss to lock.

[0016] By adopting the above technical solution, a limiting boss is provided. When the locking component is locked in the locking hole, the limiting boss locks into the annular groove on the locking component, thereby limiting the locking component.

[0017] Optionally, the limiting boss is semi-circular, the side of the limiting boss near the locking member is arc-shaped, and the cross-section of the annular groove is a fan shape that matches the side of the limiting boss.

[0018] By adopting the above technical solution, the side of the limiting boss is an arc-shaped surface, and the cross-section of the annular groove is adapted to the limiting boss. Thus, during the rotation of the second clamping plate, only a large force needs to be applied to the second clamping plate to make the limiting boss jammed in the annular groove or to make the limiting boss disengage from the annular groove.

[0019] Optionally, the first clamping plate is provided with a first elastic member that forces the limiting boss to slide and engage with the annular groove.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The device is equipped with a first clamping plate and a second clamping plate. When a reinforcing plate needs to be pasted, the flexible circuit board is first installed on the first clamping plate through the positioning component. The flexible circuit board is then clamped by the first and second clamping plates. The reinforcing plate is placed in the positioning groove and positioned by the positioning groove, so that the reinforcing plate is pasted on the flexible circuit board. This improves both the accuracy and efficiency of pasting.

[0022] 2. The side of the limiting boss is an arc-shaped surface, and the cross-section of the annular groove is adapted to the limiting boss. Thus, during the rotation of the second clamping plate, only a large force needs to be applied to the second clamping plate to make the limiting boss engage in the annular groove or disengage from the annular groove.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] Example 1:

[0031] This application discloses an auxiliary tool for attaching FPC reinforcing plates. (Refer to...) Figure 1 The system includes a first clamping plate 1 and a second clamping plate 2, which are parallel in length and hinged together. The first clamping plate 1 has a positioning element for positioning the circuit board, and the second clamping plate 2 has a positioning groove 21. When the circuit board is mounted on the first clamping plate 1, the position of the positioning groove 21 corresponds to the position on the first clamping plate 1 where a reinforcing plate needs to be installed.

[0032] Reference Figure 1 The positioning components are arranged in several groups, which are distributed along the width direction of the first clamping plate 1. Several positioning slots 21 are provided, each corresponding to one of the groups of positioning components. Each group of positioning components includes several positioning rods 11, which are distributed on the first clamping plate 1. The positions of the positioning rods 11 correspond to the positioning holes on the circuit board. One end of each positioning rod 11 is fixedly connected to the first clamping plate 1, and the axis of the positioning rod 11 is perpendicular to the surface of the first clamping plate 1.

[0033] Reference Figure 1 and Figure 2 A heating platform 3 is detachably installed on the side of the first clamping plate 1 away from the second clamping plate 2, which can accelerate the curing speed of the adhesive and improve the stability of the bonding.

[0034] The implementation principle of the FPC reinforcing plate pasting auxiliary tool in this application embodiment is as follows: a first clamping plate 1 and a second clamping plate 2 are provided. When it is necessary to paste the reinforcing plate, the flexible circuit board is first installed on the first clamping plate 1 through the positioning member. The flexible circuit board is clamped by the first clamping plate 1 and the second clamping plate 2. The reinforcing plate is placed in the positioning groove 21 and positioned by the positioning groove 21, so that the reinforcing plate is pasted on the flexible circuit board, which improves both the pasting accuracy and the pasting efficiency.

[0035] Example 2:

[0036] The difference between Example 2 and Example 1 is that, referring to Figure 3 and Figure 4 The second clamping plate 2 is provided with a locking member 22, which is located at the free end of the second clamping plate 2. The locking member 22 is fixedly connected to the side of the second clamping plate 2 near the first clamping plate 1. The first clamping plate 1 is provided with a locking hole 15 for the locking member 22 to be locked.

[0037] Reference Figure 3 and Figure 4 The locking member 22 is hemispherical. The locking holes 15 are distributed along the length of the first clamping plate 1. The two sides of the wall are provided with first sliding grooves 12. The first clamping plate 1 is provided with limiting bosses 13. There are two limiting bosses 13. The two limiting bosses 13 are located in the two first sliding grooves 12 respectively. The limiting bosses 13 slide along the length of the first clamping plate 1 and are connected to the first sliding grooves 12. By sliding the limiting bosses 13, the limiting bosses 13 can be locked onto the locking member 22. The peripheral wall of the locking member 22 is provided with annular grooves 23 for the limiting bosses 13 to be locked.

[0038] Reference Figure 3 and Figure 4The limiting boss 13 is semi-circular, and the U-shaped opening of the limiting boss 13 faces the direction of the locking member 22. The side of the limiting boss 13 near the locking member 22 is an arc-shaped convex surface, and the cross-section of the annular groove 23 is a fan shape that matches the side of the limiting boss 13.

[0039] Reference Figure 3 and Figure 4 The first clamping plate 1 is provided with a first elastic element that forces the limiting boss 13 to slide and be locked in the annular groove 23. The first elastic element is a spring 14. The spring 14 is located in the first sliding groove 12. One end of the spring 14 is fixedly connected to the groove wall of the first sliding groove 12, and the other end of the spring 14 is fixedly connected to the limiting boss 13.

[0040] Reference Figure 5 A pressure plate 4 is provided at the free end of the second clamping plate 2. The pressure plate 4 is located on the side of the second clamping plate 2 away from the first clamping plate 1. The length direction of the pressure plate 4 is parallel to the length direction of the second clamping plate 2. The side of the pressure plate 4 near the free end of the second clamping plate 2 is hinged to the second clamping plate 2. Several pressure strips 41, each corresponding to a positioning groove 21, are fixedly connected to the side of the pressure plate 4 near the second clamping plate 2. When the pressure plate 4 is rotated to be parallel to the second clamping plate 2, the pressure strips 41 can pass through the positioning groove 21 and press against the reinforcing plate.

[0041] The implementation principle of Example 2 is as follows: a locking component 22 is provided, which is locked in the locking hole 15, thereby fixing the first clamping plate 1 and the second clamping plate 2 and improving the stability of the circuit board installation.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
