DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0031] Reference Figure 1 and 2As shown, the utility model provides a bending device, which is installed on a bending device, including: a first pressure block 1, used for bending the FPC100 in the first section, the first pressure block 1 is provided with a first avoidance groove 11, and the first avoidance groove 11 is used to avoid the microphone 101 on the FPC100 below the first pressure block 1; a spring top pressure block 2, used for bending the FPC100 in the second section, the spring top pressure block 2 is provided with a second avoidance groove 21, used to avoid the foam on the FPC100 below the spring top pressure block 2; a second pressure block 3, the second pressure block 3 and the first pressure block 1 are respectively arranged on both sides of the spring top pressure block 2, and the second pressure block 3 is used for bending the FPC100 in the third section; a support plate 4, arranged below the spring top pressure block 2 and the second pressure block 3, used for supporting the FPC100, the support plate 4 is provided with a third avoidance groove 41, and the third avoidance groove 41 is used to avoid the first connector 102 on the FPC100.

[0032] Preferably, the end of the first pressing block 1 is provided with a first chamfered C-angle 12. When the first pressing block 1 is pressed down, the FPC 100 is gradually pressed together from both sides of the microphone 101 by the first chamfered C-angle 12 in a buffering manner to achieve a 90° bend of the FPC 100. Since the first pressing block 1 requires a small space at the bend of the FPC 100, the microphone 101 is avoided by the first avoidance groove 11 to prevent the microphone 101 from being crushed. The first chamfered C-angle 12 is used to avoid and slowly bend the product to 90° to avoid damage to the product. Figure 5 shown.

[0033] like Figure 6 As shown, the end of the second pressing block 3 is provided with a bending forming press head, and the bending forming press head is provided with a first chamfer 31 and a second chamfer C angle 32. The second chamfer C angle 32 is 120°. When the second pressing head 3 is pressed down, when the FPC 100 is pressed down, the first chamfer 31 can bend the FPC 100 to 90°, and the second chamfer C angle 32 can bend the FPC 100 to 120°. Due to the characteristics of the FPC 100 itself, the FPC 100 will rebound after being bent, and the angle after rebound is 90°±30°.

[0034] In this embodiment, the third avoidance groove 41 and the second avoidance groove 21 are arranged opposite to each other up and down.

[0035] like Figure 3 As shown, the support plate 4 includes a planar support portion 42 and a bending support portion 43. The planar support portion 42 and the bending support portion 43 constitute a bending forming portion 411 adapted to the end of the second pressing block 3. A bending buffer zone 44 and a deformation reserved zone 45 for bending the FPC 100 are respectively provided on both sides of the bending support portion 43.

[0036] Furthermore, the two sides of the planar support portion 42 are provided with second rounded corners 421. The second rounded corners 421 are provided so that the FPC 100 located on both sides of the second connector 103 has a certain curvature during the bending process, thereby avoiding damage to the internal connection wires of the FPC 100 caused by the bending transition.

[0037] Preferably, the end of the support plate 4 is further provided with a positioning block 46 for limiting the position of the FPC 100. The positioning block 46 is provided with a limiting step 461, and the width of the limiting step 461 is 0.2 mm. Figure 4 As shown, when the FPC 100 is placed on the support plate 4 , a gap of 0.2 mm can be retained between the edge of the FPC 100 and the positioning block 46 . This design can prevent the FPC 100 from being damaged when being bent and pressed.

[0038] Embodiment 2

[0039] like Figure 6 As shown, the utility model also provides a microphone module, which is made by the bending device of the microphone module described in the first aspect, including FPC100, a microphone 101, a first connector 102 and a second connector 103, wherein the microphone 101 is arranged on the upper surface of the FPC100, the first connector 102 is arranged on the lower surface of the FPC100, a first reinforcing sheet 104 is provided on the opposite side of the FPC 100 to the microphone 101, a second reinforcing sheet 105 is provided on the opposite side of the FPC 100 to the first connector 102, and a third reinforcing sheet 106 is provided on the opposite side of the FPC 103 to the second connector 103.

[0040] Furthermore, a buffer 107 is included, and the buffer 107 is arranged above the second reinforcing sheet 104. In this embodiment, the buffer 105 is foam, which is adhered to the second reinforcing sheet 104 by double-sided adhesive. When the elastic pressing block 2 is pressed down, the foam plays a buffering role, which can prevent the first connector 102 from being crushed by the spring pressing block 2.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
