Description

Technical Field

[0001] The utility model relates to the technical field of bending devices, in particular to an FPC over-bending device. Background Art

[0002] Customers have increasingly stringent requirements on the delivery quality of electronic products, and flexible circuit boards are used in the assembly of electronic products. Figure 1 The figure shows an FPC 100 with two bent ends 101 that need to be bent to the target angle. Traditional FPC bending jigs use a vertical downward pressure mechanism that folds the FPC into shape through mechanical pressure. However, due to the characteristics of FPC materials, the angle easily rebounds after bending, making it difficult to meet customer requirements for angle accuracy. Manual adjustment is required, which restricts production efficiency. Manual adjustment is time-consuming and inconsistent, which can easily lead to quality issues such as uneven force and angle deviation.

[0003] Chinese patent CN222621286U discloses an FPC over-bending device for LCP materials. Multiple heating modules heat the FPC's bent end from multiple directions, softening the LCP material and making it easier to deform, resulting in a Z-shaped bend. This device is designed for materials that require heat setting, using a horizontally moving bending pusher to bend the FPC's bent end. However, if the overall height of the bent end is very small, this bending pusher cannot properly shape the bent end, resulting in an unsatisfactory bend angle.

[0004] Therefore, it is necessary to improve the device structure to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide an FPC over-bending device, which can make the bent end with a smaller height more easily achieve the required accuracy by obliquely extruding the over-bending.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions: an FPC over-folding device, comprising:

[0009] A pressing assembly, which is provided on the upper portion of the frame and includes a pressing block for pressing the FPC onto the positioning support plate;

[0010] The bending assembly is arranged on one side of the pressing assembly close to the stepped bending portion, and includes a bending block moving downward from the upper side. The bending block forms a bent end by pressing one side of the FPC onto the stepped bending portion.

[0011] Specifically, the frame includes a base and a support frame arranged at the rear of the base, the positioning support plate is arranged at the front of the base, the clamping assembly also includes a lifting plate and a lifting drive member, the pressure block is arranged at the bottom of the lifting plate, and the lifting drive member is fixed on the support frame and drives the lifting plate to rise and fall.

[0012] Furthermore, the lifting drive member is a quick clamp.

[0013] Specifically, the bending assembly includes several bending blocks, a slide, a skateboard and an inclined sliding drive member. The slide is provided with a pair of slide rails to guide the sliding of the skateboard. The bending blocks are all fixed on the skateboard. The inclined sliding drive member is fixed on the top of the slide and drives the skateboard to slide.

[0014] Furthermore, the slope angle of the slide rail is 10~80°.

[0015] Furthermore, the oblique sliding driving member is a quick clamp.

[0016] Furthermore, the frame includes a base and a support frame arranged at the rear of the base, the clamping assembly also includes a lifting plate and a lifting drive member, the pressure block is arranged at the bottom of the lifting plate, the lifting drive member is fixed on the support frame and drives the lifting plate to rise and fall, the slide is fixed on the lifting plate, and the moving path of the bending block passes through the lifting plate.

[0033] The present invention will be further described in detail below with reference to specific embodiments.

[0034] Example:

[0035] like Figure 2 and Figure 3 As shown, an FPC over-bending device 200 of the present invention includes a frame 1, a positioning support plate 2 provided at the lower part of the frame 1, a pressing assembly 3 provided at the upper part of the frame 1, and a bending assembly 4 provided at one side of the positioning support plate 2.

[0036] The frame 1 is the fixed base of the entire FPC folding device 200, the positioning tray 2 is used to support and position the FPC100, the clamping component 3 is used to press the FPC100 on the positioning tray 2 in a determined posture, and the bending component 4 folds one side of the FPC100 from obliquely above to form a bent end 101.

[0037] like Figure 2 As shown, the frame 1 includes a base 11, a support frame 12 provided at the rear of the base 11, and a plurality of columns 13 provided on the base 11. A positioning plate 2 is provided at the front of the base 11. The upper portion of the positioning plate 2 is provided with a contoured positioning groove 21 for positioning the FPC 100, and one side is provided with a stepped bend 22.

[0038] The contoured positioning groove 21 has a groove structure that corresponds to the structure of the FPC 100. The bent end 101 of the FPC 100 extends above the stepped bend 22 and is exposed to one side. The end of the bending block 41 has a contoured structure that allows it to approach the bent end 101 from above and then cooperate with the stepped bend 22 to complete the over-bend (bending angle exceeding 90°).

[0039] like Figures 2 to 5 As shown, the clamping assembly 3 is connected to the front of the support frame 12 and includes a pressure block 31, a lifting plate 32, and a lifting drive 33. The pressure block 31 is located at the bottom of the lifting plate 32, which is passed through by all the columns 13. The lifting plate 32 is provided with linear bearings 321 corresponding to the columns 13. The columns 13 guide the linear bearings 321 for vertical movement. The lifting drive 33 is fixed to the support frame 12 and drives the lifting plate 32 to move up and down. The lifting drive 33 in this embodiment is a quick clamp.

[0040] The pressure block 31 is used to press the positioned FPC 100 onto the positioning plate 2. The lifting and lowering movement of the pressure block 31 is driven by the lifting drive 33, and the medium between the two is the lifting plate 32. The lifting plate 32 needs to move vertically under the guidance of the column 13, so that the pressure block 31 presses the FPC 100 from top to bottom. Although the lifting drive 33 can theoretically use automatic components such as cylinders and linear modules, because the FPC 100 targeted by this device is not large, the pressing operation can be completed manually, so the use of quick clamps can achieve a very fast processing speed.

[0041] like Figure 2 、 Figure 3 and Figure 6 As shown, the bending assembly 4 is located on the side of the positioning plate 2 near the stepped bend 22. The bending assembly 4 comprises several bending blocks 41, a carriage 42, a slide plate 43, and an inclined sliding drive 44. The carriage 42 is fixed to the lifting plate 32. The carriage 42 is equipped with a pair of guide rails 421 that guide the slide plate 43. The guide rails 421 have a slope angle of 10 to 80 degrees. The bending blocks 41 are all fixed to the slide plate 43. The inclined sliding drive 44 is fixed to the top of the carriage 42 and drives the slide plate 43. The movement path of the bending blocks 41 passes through the lifting plate 32. In this embodiment, the inclined sliding drive 44 is also a quick clamp.

[0042] Although the slide 42 can be fixed on the base 11, it is not as good as the method in the embodiment in that it can fix the relative position with the pressure block 31 (because both are connected to the lifting plate 32). In this way, the end of the bending block 41 is more stable in its position relative to the bending end 101. Because there may be multiple bending ends 101 on the same side of the FPC 100, multiple bending blocks 41 can be used, but they need to be connected with the same slide 43 to maintain the same movement. In addition, the bending block 41 can also be replaced to meet the requirements of various angles. The slide 43 cooperates with the slide rail 421 to determine the sliding direction. Although the inclined sliding drive 44 can theoretically also use automatic components such as cylinders and linear modules, because the FPC 100 targeted by this device is not large in size, the bending operation can also be completed manually, so a quick clamp can be used to achieve a very fast processing speed.

[0043] The working process of the FPC over-folding device 200 is as follows:

[0044] 1. When the lifting plate 32 is raised, place the FPC 100 in a specific posture into the contoured positioning groove 21 so that the bent end 101 to be bent is located above the stepped bending portion 22;

[0045] 2. Operate the lifting drive 33 to lower the lifting plate 32. The pressing block 31 and the bending assembly 4 will then lower together. The pressing block 31 will cooperate with the positioning support plate 2 to press the FPC 100 tightly and prevent it from moving arbitrarily.

[0046] 3. Operate the oblique sliding drive member 44 to move the bending block 41 obliquely downward until the bending portion 22 is pressed against the stepped bending portion 22 and hold for 5 seconds to ensure that the FPC 100 is directly shaped after being folded back.

[0047] The utility model avoids the problem that the vertical downward pressing method cannot effectively shape and requires secondary manual intervention. The bending portion 101 is folded obliquely, and the pressure is concentrated at the corner, which avoids the rebound of the folded angle, and the desired angle is obtained in one go, with a fast processing rhythm.

[0048] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
