DETAILED DESCRIPTION

[0029] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0030] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.

[0031] like Figures 1-6 As shown, an embodiment of the present invention provides a flexible circuit board bending machine, including a product positioning mechanism 100 , a clamping and bending component 200 and a moving mechanism 300 .

[0032] The product positioning mechanism 100 is used to fix the product 400 at the bending station.

[0033] In a specific embodiment, referring to Figure 2 The product positioning mechanism 100 includes a product feeding turntable 110 and a plurality of product fixing positions 120 distributed circumferentially on the product feeding turntable 110. By rotating the product feeding turntable 110, the products 400 fixed at each product fixing position 120 can be rotated to the bending station in sequence.

[0034] It should be noted that in order to facilitate clamping and bending of the flexible circuit board 410 on the product 400, when the product 400 is fixed on the product fixing position 120, the flexible circuit board 410 to be bent is exposed from the product fixing position 120, and there are no redundant structures or obstacles around it.

[0035] The clamping and bending component 200 includes a clamping action unit 210 and a rotating shaft module 220 for driving the clamping action unit 210 to rotate. The clamping action unit 210 is provided with two oppositely arranged clamping blocks 211. The two clamping blocks 211 can be opened or clamped under the drive of the clamping action unit 210. The clamping action unit 210 preferably adopts a clamping cylinder.

[0036] It is understandable that, in addition to the clamping cylinder, the clamping action unit 210 may also adopt other grasping and clamping action mechanisms, such as a hydraulic clamping mechanism, an electric clamping claw, a magnetic clamping mechanism, etc., which is not limited in this embodiment.

[0037] In order to reduce the damage to the flexible circuit board 410 caused by the clamping blocks 211 of the clamping action unit 210 , buffer pads 212 are provided on the opposite inner sides of the two clamping blocks 211 . The buffer pads 212 are preferably rubber blocks.

[0038] The moving mechanism 300 is used to drive the clamping and bending component 200 to move, so that the two clamping blocks 211 can move and clamp both sides of the flexible circuit board 410 of the product 400 at the bending station.

[0039] In a specific embodiment, referring to Figure 3 、 Figure 5 and Figure 6 The moving mechanism 300 includes a Y-axis linear module 310 and an X-axis linear module 320. The Y-axis linear module 310 is fixed on the base 314, and the X-axis linear module 320 is installed on the Y-axis linear module 310, so that the Y-axis linear module 310 can drive the X-axis linear module 320 to translate along the Y-axis. The clamping and bending component 200 is installed on the X-axis linear module 320, so that the X-axis linear module 320 can drive the clamping and bending component 200 to translate along the X-axis.

[0040] By adopting the above structure, the clamping and bending component 200 can be driven to translate in the Y-axis direction by the Y-axis linear module 310, and the clamping and bending component 200 can be driven to translate in the X-axis direction by the X-axis linear module 320, thereby realizing the movement of the clamping and bending component 200 in the plane space.

[0041] Specifically, the Y-axis linear module 310 includes a Y-axis slide 311, a Y-axis slider 312 installed on the Y-axis slide 311, and a Y-axis linear drive mechanism 313 for driving the Y-axis slider 312 to slide along the Y-axis slide 311. The Y-axis slide 311 is fixed on the base 314, and the Y-axis linear drive mechanism 313.

[0042] The X-axis linear module 320 includes an X-axis slide 321, an X-axis slider 322 installed on the X-axis slide 321, and an X-axis linear drive mechanism 323 for driving the X-axis slider 322 to slide along the X-axis slide 321. A supporting slide 315 parallel to the Y-axis slide 311 is provided on the base 314, and a driven slider 316 is slidably installed on the supporting slide 315. One end of the X-axis slide 321 is fixed on the Y-axis slider 312, and the other end of the X-axis slide 321 is fixed on the driven slider 316.

[0043] The clamping and bending component 200 is fixed on the X-axis slider 322 .

[0044] In this embodiment, both the Y-axis linear drive mechanism 313 and the X-axis linear drive mechanism 323 adopt a structure in which a servo motor is connected to a ball screw.

[0045] It is understandable that in other embodiments, the Y-axis linear drive mechanism 313 and the X-axis linear drive mechanism 323 also use pneumatic, electric or hydraulic telescopic push rods.

[0046] The product 400 is fixed at the bending station and the flexible circuit board 410 is exposed. When the flexible circuit board 410 is bent, the clamping and bending component 200 is first driven to move by the moving mechanism 300, so that the two open clamping blocks 211 are moved to the appropriate positions on both sides of the flexible circuit board 410, and then the clamping action unit 210 is controlled to drive the two clamping blocks 211 to clamp the flexible circuit board 410, and then the clamping action unit 210 is driven to rotate by the rotating shaft module 220 to bend the flexible circuit board 410.

[0047] Therefore, the present application realizes the automatic bending of the flexible circuit board 410 of the product 400. Compared with the prior art, there is no need to use a bending jig, which improves the efficiency of bending the flexible circuit board 410 and solves the problem of the troublesome change of the product 400.

[0048] In some embodiments, reference Figure 3 and Figure 4The rotating shaft module 220 includes a mounting base 221 and a rotating power unit 222 fixed to the mounting base 221. The rotating power unit 222 is preferably a rotating motor. An adjustment rail 230 is provided at the end of the rotating output shaft of the rotating power unit 222. The adjustment rail 230 extends perpendicular to the axial direction of the rotating output shaft. The clamping action unit 210 is slidably mounted on the adjustment rail 230 and can be locked to the adjustment rail 230 via a locking member.

[0049] This embodiment does not impose any specific restrictions on the structural type of the locking member. Its function is to lock the clamping action unit 210 on the adjustment rail 230. When the locking member is unlocked, the position of the clamping action unit 210 can be adjusted along the adjustment rail 230. The locking member can specifically adopt a locking positioning structure such as a locking bolt and a pin.

[0050] Because the lengths and positions of the flexible circuit boards 410 on different products 400 vary, the positions at which the clamping blocks 211 of the clamping unit 210 clamp on the flexible circuit boards 410 also vary. Using the mobile mechanism 300 to overcome the problem of the varying positions of the clamping blocks 211 on the flexible circuit boards 410 of different products 400 would require redesigning the control program of the mobile mechanism 300. However, the present application overcomes this problem by adjusting the position of the clamping unit 210 on the adjustable rail 230. This eliminates the need to redesign the control program of the mobile mechanism 300 and allows for compatible clamping and bending of flexible circuit boards 410 of varying lengths and positions.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
