[0022] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0023] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0024] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0025] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure.

[0028] Figure 1 and Figure 2 This is a schematic diagram of the flexible strip bending device in this embodiment. Figure 3 This is an exploded view of the flexible strip bending device in this embodiment.

[0029] In some implementations, such as Figures 1-3 As shown, the flexible belt bending device includes a bending component 1, a support portion 2, a first displacement mechanism 51, and a second displacement mechanism 52. The support portion 2 is movably disposed on the first displacement mechanism 51, and the bending component 1 is movably disposed on the second displacement mechanism 52.

[0030] Figure 4 This is a schematic diagram of the flexible strip A in the flattened state in this embodiment. Figure 5This is a schematic diagram of the flexible strip A in a bent state in this embodiment.

[0031] like Figures 4-5 As shown, a flexible strip bending device is used to bend a flexible strip A. The flexible strip A comprises, in sequence along its length, a first segment A1, a first bent segment A31, a second segment A2, a second bent segment A32, and a third segment A3. The flexible strip bending device bends the first bent segment A31 and the second bent segment A32 in opposite directions to form an S-shaped flexible strip A.

[0032] Figure 6 This is a schematic diagram of the structure of the support part 2 and the first shaping head 111, the second shaping head 121 and the third shaping head 131 in this embodiment. Figure 7 This is an exploded view of the support unit 2 and the first shaping head 111, the second shaping head 121 and the third shaping head 131 in this embodiment. Figure 8 This is a schematic diagram of the structure of the support part 2 and the body B in this embodiment. Figure 8 The outline of the inner side of the body B is shown by a thick dashed line, and the flexible strip A extends from the inner side of the body B.

[0033] In some implementations, such as Figures 6-7 As shown, in this embodiment, the flexible strip A can be bent by the cooperation of the first shaping head 111, the second shaping head 121, and the third shaping head 131. Further referencing... Figure 5 and Figure 9 As shown, during the bending process of the bending component 1 bending the flexible strip A, the third segment A3 is located in the body B and is fixedly connected to the body B.

[0034] Optionally, the flexible strip A can be a flexible printed circuit board (FPC) or a flat cable (using plastic materials to press multiple wire cores into a single unit under high temperature and pressure). For example... Figure 5 As shown in the figure, the flexible strip A is a flexible circuit board, and a communication interface A4 is provided on the first segment A1.

[0035] Optionally, the body B is the frame of an electronic device. Taking the mid-frame of a mobile phone as an example, the third segment A3 is located inside the mid-frame and is communicatively connected to the first electronic component of the mobile phone. The second curved segment A32 extends from the inner side of the mid-frame. After the flexible strip A is bent by the flexible strip bending device, the communication interface A4 is away from the second segment A2, so that the communication interface A4 can communicate with the second electronic component of the mobile phone. A mounting surface B1 is formed on the inner side adjacent to the second curved segment A32.

[0036] Figures 9-11 This is a schematic diagram of the working state of the bending process of the second bending segment A32 in this embodiment. Figures 12-15This is a schematic diagram of the working state of the pre-bending process of the first bending segment A31 in this embodiment. Figures 16-18 This is a schematic diagram of the working state of the pressing process of the first curved section A31 in this embodiment. The third section A3 is shown with a dashed line, and the first section A1, the second section A2, the first curved section A31 and the second curved section A32 are shown with thick dashed lines.

[0037] In some implementations, such as Figures 6-8 As shown, the support portion 2 has a contour groove 21 for setting the product. The body B can be fixed within the contour groove 21 to prevent movement of the body B when the flexible strip A is bent. Further referring to... Figure 3 As shown, the bending assembly 1 includes a first forming part 11 and a second forming part 12. The first forming part 11 includes a first shaping head 111, which has a first forming surface 31 and a suction hole 311. The second forming part 12 includes a second shaping head 121, which has a second forming surface 32 and a third forming surface 33. The second forming surface 32 and the third forming surface 33 are at a predetermined angle and are connected to each other to form a forming flange 34. The first shaping head 111 and the second shaping head 121 form a clamping pair 14 (e.g., Figure 14 (As shown).

[0038] Further reference Figures 12-15 As shown, the bending assembly 1 has a pre-bending process. In the pre-bending process, the suction hole 311 adsorbs the first segment A1, the clamping pair 14 clamps the first segment A1 through the first forming surface 31 and the second forming surface 32, and the second segment A2 is located between the third forming surface 33 and the mounting surface B1. The first bent segment A31 is wrapped around the forming flange 34 (e.g., Figure 15 (as shown in the diagram).

[0039] Optionally, the operator may use a bending tool (e.g., a cotton swab) to move the first segment A1 toward the first molding surface 31, causing the first segment A1 to bend and adhere to the first molding surface 31. When the first segment A1 is provided with a communication interface A4, the communication interface A4 may also be pushed into the suction hole 311 to ensure the stability of the connection between the first segment A1 and the first molding surface 31.

[0040] Optionally, during this process, the clamping pair 14 deforms by pulling the flexible belt A through the first segment A1, causing the flexible belt A to move toward the mounting surface B1 until the mounting surface B1 faces the first segment A1 and the second segment A2.

[0041] Further reference Figures 16-18 As shown, the bending assembly 1 also includes a clamping process. In the clamping process, the clamping pair 14 presses the second segment A2 against the mounting surface B1 (e.g., via the third forming surface 33) through the third forming surface 33. Figure 16(As shown). During this process, the clamping pair 14 maintains the clamping state of the first segment A1, thereby realizing the bending of the first bending segment A31 and the second bending segment A32. The bending assembly 1 is also configured such that when the second shaping head 121 moves away from the first shaping head 111, the first forming surface 31 presses against the first segment A1 against the second segment A2 (as shown). Figures 17-18 (As shown). During this process, the second shaping head 121 is used to avoid the first shaping head 111 so that after the first shaping head 111 adjusts the direction of the first segment A1, it presses the first segment A1 onto the second segment A2.

[0042] In summary, the flexible strip bending device in this embodiment has a first forming surface 31 on the first forming head 111, and a second forming surface 32 and a third forming surface 33 on the second forming head 121. The first forming head 111 and the second forming head 121 form a clamping pair 14 through the first forming surface 31 and the second forming surface 32. The second forming surface 32 and the third forming surface 33 are connected to form a forming flange 34. Thus, the clamping pair 14 clamps the first segment A1 to pull the flexible strip A, so that during the pre-bending process, the mounting surface B1 of the flexible strip A can face the first segment A1 and the second segment A2, and the first bent segment A31 is wrapped around the forming flange 34. Therefore, during the pressing process, the second forming head 121 and the first forming head 111 press the second segment A2 and the first segment A1 respectively, realizing the bending operation of the first bent segment A31 and improving the morphological accuracy of the flexible strip A after bending. On the other hand, the first shaping head 111 and the second shaping head 121 can be used together to pull the flexible band A, or used separately to allow the first shaping head 111 to independently bend the first segment A1. Thus, when the flexible band A and the body B are connected, the bending assembly 1 can operate in a smaller space and reduce the pulling on the connection point between the flexible band A and the body B.

[0043] In some implementations, such as Figure 9 , Figure 11 and Figure 16 As shown, when clamping pair 14 is in the clamping state (e.g.) Figure 16 (As shown in the diagram), the forming flange 34 is located on one side of the first forming surface 31 and bends away from the second forming surface 32 and the third forming surface 33. That is, when the first shaping head 111 and the second shaping head 121 are engaged to form the clamping pair 14, the first shaping head 111 and the second shaping head 121 are in a mutually offset state. In this form, the first bent segment A31 located on the forming flange 34 is offset from the first forming surface 31. When the first forming surface 31 presses against the first segment A1, it can prevent the first forming surface 31 from squeezing the first bent segment A31 (e.g., ...). Figure 18 (As shown).

[0044] In some implementations, such as Figure 14As shown, in the pre-bending process, the bending assembly 1 drives the first shaping head 111 to rotate the first segment A1 toward the second forming surface 32 along the first direction (as shown by arrow r1) until the clamping pair 14 clamps the first segment A1.

[0045] Further reference Figure 16 and Figure 17 As shown, in the pressing process, after the third forming surface 33 presses against the second segment A2 on the mounting surface B1, the first shaping head 111 rotates in the second direction (as shown by arrow r2) to move the first segment A1 away from the second shaping head 121. Further referencing... Figure 18 As shown, the first shaping head 111 is along the first direction (e.g.) Figure 18 (As indicated by the middle arrow r1) Rotate again until the second forming surface 32 and the mounting surface B1 are in a relative position. The first direction is opposite to the second direction. In this configuration, the first shaping head 111 moves linearly towards the mounting surface B1 to press the first segment A1 against the second segment A2, or directly presses the first segment A1 onto the second segment A2 during the rotation of the first shaping head 111. Thus, driving the first shaping head 111 by rotation helps it avoid the second shaping head 121, and during the movement, ensures that the second segment A2 is in contact with the mounting surface B1, preventing the first shaping head 111 from pulling on the second segment A2.

[0046] In some implementations, such as Figure 16 As shown, the bending assembly 1 also includes a third forming part 13. The third forming part 13 includes a third shaping head 131, which has a forming groove 35. In the pre-bending process, the forming flange 34 engages with the forming groove 35 to press against the first bent segment A31. Thus, the forming flange 34 and the forming groove 35 clamp the first bent segment A31, ensuring the morphological accuracy of the first bent segment A31 after the second shaping head 121 separates from the flexible strip A.

[0047] In some implementations, such as Figure 7 As shown, the third forming section 13 also includes a forming base plate 132, which is located at the bottom of the first forming head 111, the second forming head 121, and the third forming head 131. The top of the forming base plate 132 has a forming plane 36. Further referring to... Figures 15-18 As shown, during the pressing process, the forming plane 36 corresponds at least partially to the bottom edge of the flexible strip A. Therefore, during the bending process of the flexible strip A, misalignment of the first segment A1 and the second segment A2 in the width direction of the flexible strip A is avoided.

[0048] Preferably, in the pre-bending process, a forming base plate 132 can also be provided at the bottom of the flexible strip A to ensure that the bottom edge of the flexible strip A is in the same plane during the pulling process of the clamping pair 14. The forming base plate 132 is fixedly connected to the second shaping head 121, so that the forming base plate 132 and the third shaping head 131 move synchronously, thereby simplifying the driving method of the forming base plate 132.

[0049] Optionally, the forming base plate 132 includes a first plate and a second plate, which are vertically connected to form an L-shaped structure. The extension direction of the first plate is perpendicular to the mounting surface B1. During the clamping process, the edge of the first plate away from the second plate abuts against the inner side of the middle frame and is located below the mounting surface B1.

[0050] Figure 19 This is a schematic diagram of the structure of the mounting plate 4, the first displacement mechanism 51, and the second displacement mechanism 52 in this embodiment.

[0051] In some implementations, such as Figure 3 and Figure 19 As shown, the flexible belt bending device also includes a mounting plate 4, a first displacement mechanism 51, and a second displacement mechanism 52. The first displacement mechanism 51 is disposed on the mounting plate 4 and includes a lifting plate 511. The bearing part 2 is detachably disposed on the lifting plate 511, and the lifting plate 511 can operably drive the bearing part 2 to move up and down (e.g., Figure 19 (As indicated by the middle arrow D1). The second displacement mechanism 52 is disposed on the mounting plate 4 and includes a first translation plate 521, which operably drives the bending assembly 1 along a third direction (e.g., Figure 19 Move horizontally (as indicated by the middle arrow D2).

[0052] Specifically, the mounting plate 4 is provided with a clearance window, and the lifting plate 511 abuts against the bottom of the supporting part 2 through the clearance window. The first sliding plate 521 is parallel to the mounting plate 4 and spaced above the mounting plate 4. A sliding assembly is provided between the first sliding plate 521 and the mounting plate 4. The sliding assembly includes a slide rail and a slider.

[0053] Optionally, the operator can first place the product in the contour groove 21, and then place the support part 2 on the lifting plate 511. The lifting plate 511 is in a lower position. In this configuration, the bending assembly 1 is moved by the first translation plate 521, causing the first shaping head 111, the second shaping head 121, the third shaping head 131, and the forming base plate 132 to move above the contour groove 21 and adjacent to the flexible belt A. Finally, the lifting plate 511 moves upward. This allows the first shaping head 111, the second shaping head 121, the third shaping head 131, and the forming base plate 132 to cross the middle frame and enter a position opposite to the inner side of the middle frame. After the bending process is completed, the lifting plate 511 is lowered, driving the bending assembly 1 to reset, thereby removing the support part 2.

[0054] Figure 20 This is an exploded view of the bending component 1 and the mounting plate 4 in this embodiment. Figure 21 This is an exploded view of the position adjustment mechanism 135 in this embodiment. Figure 22 and Figure 23 This is an exploded view of the third displacement mechanism 53, the first molding part 11, and the second molding part 12 in this embodiment.

[0055] In some implementations, such as Figure 3 , Figure 20 , Figure 22 and Figure 23 As shown, the flexible belt bending device also includes a third displacement mechanism 53. The third displacement mechanism 53 is disposed on the first translation plate 521 and includes a second translation plate 531. A first forming part 11 and a second forming part 12 are disposed on the second translation plate 531, and a third forming part 13 is disposed on the first translation plate 521. The second translation plate 531 operably drives the bending assembly 1 along a fourth direction (e.g., ...). Figure 19 Move horizontally in the direction indicated by the middle arrow D3. The third direction is perpendicular to the fourth direction.

[0056] Specifically, the flexible belt bending device also includes a vertical plate 41, which is perpendicularly connected to the mounting plate 4. A third displacement mechanism 53 is disposed on the vertical plate 41, and a second translation plate 531 is parallel to and spaced apart from the vertical plate 41. When the third displacement mechanism 53 and the second displacement mechanism 52 are driven, the clamping pair 14 can be moved horizontally. During the process of the clamping pair 14 pulling the flexible belt A, it is ensured that the clamping pair 14 stably clamps the first segment A1, and the magnitude of the clamping force is prevented from changing.

[0057] Figure 24 This is an exploded view of the first shaping head 111 and the second shaping head 121 in this embodiment.

[0058] In some implementations, such as Figure 7 , Figure 9 , Figure 20 and Figure 24 As shown, the first forming section 11 further includes a first driving member 112 and a first rotary actuator 113. The first driving member 112 includes a first shaping head 111 and an air passage 1121, which communicates with the suction hole 311. A vacuum pump is connected to the air passage 1121 via an air pipe to provide negative pressure suction for the suction hole 311. The first rotary actuator 113 is used to drive the first driving member 112 to rotate in a first direction or a second direction.

[0059] Optionally, the first drive member 112 has a rotation axis (e.g., Figure 7 and Figure 9As indicated by the symbol Ⅰ, the first driving member 112 rotates along the rotation axis under the drive of the first rotary driver 113. The rotation axis is offset from the first shaping head 111, so that the first shaping head 111 has a large rotation radius.

[0060] In some implementations, such as Figure 7 , Figure 20 , Figure 22 and Figure 23 As shown, the second forming section 12 further includes a second driving member 122, a first linear actuator 123, and a second linear actuator 124. The second driving member 122 includes a second shaping head 121. The first linear actuator 123 drives the second driving member 122 to move in a third direction. The second linear actuator 124 drives the first linear actuator 123 and the second driving member 122 to move in a fourth direction.

[0061] In this embodiment, the first linear actuator 123 and the second linear actuator 124 cooperate to drive the second shaping head 121 to move horizontally relative to the first shaping head 111, so that the second shaping head 121 can engage with the first shaping head 111 to form a clamping pair 14, or the second shaping head 121 can move away from the first segment A1 to avoid the first shaping head 111. At the same time, during the process of the clamping pair 14 pulling the flexible belt A, the first linear actuator 123 and the second linear actuator 124 can remain stationary, so that the clamping force remains unchanged.

[0062] In some implementations, such as Figure 3 and Figures 20-21 As shown, the third forming section 13 further includes a third driving member 133, a third linear actuator 134, and a position adjustment mechanism 135. The third driving member 133 includes a third shaping head 131. The third linear actuator 134 is used to drive the third driving member 133 to move in a fourth direction. The position adjustment mechanism 135 includes a first elastic member 1353, a moving member 1354, an adjusting member 1355, a first fixed seat 1351, and a second fixed seat 1352. One end of the first elastic member 1353 abuts against the first fixed seat 1351, and the other end abuts against the moving member 1354. The adjusting member 1355 is movably disposed on the second fixed seat 1352 and abuts against the side of the moving member 1354 away from the first elastic member 1353. The moving member 1354 and the third driving member 133 move synchronously in a third direction.

[0063] It is easy to understand that the position adjustment mechanism 135 in this embodiment is used to adjust the position of the third shaping head 131 and the forming base plate 132 in the third direction. The adjusting member 1355 can drive the moving member 1354 to translate along the third direction, so that the forming groove 35 and the forming flange 34 are aligned, avoiding misalignment between them. Furthermore, the forming flange 34 and the forming groove 35 align to form a forming gap that compresses the first curved section A31. The first elastic member 1353 can adjust the position of the third shaping head 131 in the third direction when the forming flange 34 and the forming groove 35 are aligned. Thus, the first elastic member 1353 can fine-tune the position of the third shaping head 131 to maintain a consistent forming gap width, thereby avoiding damage to the flexible strip A.

[0064] Optionally, such as Figure 21 As shown, the first elastic element 1353 is a compression spring. The moving element 1354 has a blind hole. The adjusting element 1355 is a screw. The first fixing seat 1351 has a first through hole and a plug. The plug is disposed in the first through hole and abuts against one end of the compression spring. The other end of the compression spring extends into the blind hole and abuts against the bottom of the blind hole. The second fixing seat 1352 has a second through hole and a nut. The tail of the screw rotatably passes through the second through hole and is threadedly connected to the nut. The tail of the screw abuts against the side of the moving element 1354 away from the first elastic element 1353. The head of the screw and the nut abut against the two edges of the second through hole, respectively. By rotating the screw or the nut, the operator can adjust the extension size of the screw tail to precisely change the position of the third forming part 13 in the third direction.

[0065] In some implementations, such as Figure 24 As shown, the first shaping head 111 includes a first elastic limiting body 114, which has a first forming surface 31 and a suction hole 311. The second shaping head 121 includes a second elastic limiting body 125, which has a third forming surface 33.

[0066] Optionally, the first elastic limiting body 114 is disposed in the fixing groove of the first driving member 112, and the suction hole 311 communicates with the air passage 1121. In this embodiment, the first elastic limiting body 114 and the second elastic limiting body 125 can be made of materials such as rubber or foam to avoid damaging the flexible strip A during the pressing process.

[0067] Optionally, the first positioning mechanism 51 has a fourth linear actuator. The first linear actuator 123, the second linear actuator 124, the third linear actuator 134 and the fourth linear actuator can be a linear cylinder or a linear motor.

[0068] Optionally, the second positioning mechanism 52 includes a second rotary driver. The third positioning mechanism 53 includes a third rotary driver. The first rotary driver 113, the second rotary driver, and the third rotary driver can be rotary motors. The first rotary driver 113 drives the first driving member 112 to rotate via a transmission belt and pulley mechanism. The second and third rotary drivers drive the first translation plate 521 and the second translation plate 531 to move linearly via ball screw mechanisms. This increases the motion accuracy and driving torque of the clamping pair 14.

[0069] Optionally, the mounting plate 4 has a clearance groove, and the second displacement mechanism 52 includes a drive block connected to the drive nut of the ball screw mechanism of the second rotary driver. The drive block extends upward from the lower part of the clearance groove and is connected to the first translation plate 521 to drive the first translation plate 521 to move horizontally.

[0070] Figure 25 This is a flowchart illustrating the flexible strip bending method of this embodiment.

[0071] In one alternative implementation, such as Figure 25 As shown, the flexible strip bending method in this embodiment includes the following steps.

[0072] Step S100: Bend the first segment A1 toward the first forming surface 31 so that the suction hole 311 is adsorbed onto the first segment A1.

[0073] Optionally, such as Figure 13 As shown, the operator uses a cotton swab to move the first section A1 towards the first forming surface 31. During this process, the communication interface A4 is accurately inserted into the suction hole 311.

[0074] Furthermore, such as Figures 9-11 As shown, the steps preceding step S100 include: Step S110: Bend the second segment A2 toward the first forming surface 31 so that the suction hole 311 is adsorbed onto the second segment A2.

[0075] The operator uses a cotton swab to move the second section A2 onto the first molding surface 31 so that the second section A2 fits into the first molding surface 31.

[0076] Step S120: Drive the first shaping head 111 to rotate the second segment A2 toward the second forming surface 32 along the first direction so that the clamping pair 14 clamps the second segment A2.

[0077] Step S130: Drive the clamping pair 14 close to the mounting surface B1 to bend the second bending segment A32. The flexible strip A also includes the second bending segment A32 and the third segment A3, and one end of the second bending segment A32 is connected to the second segment A2, and the other end extends into the connection window of the body B and is connected to the third segment A3.

[0078] Specifically, the flexible strip A extends from the connecting window (the specific structure of the connecting window is not shown in the figure), and the third segment A3 is fixed to the middle frame. When the clamping pair 14 moves along the inner side of the middle frame (e.g. Figure 10 (As shown by the middle arrow), the connecting window is used to limit the second curved segment A32, so that the second curved segment A32 bends away from the mounting surface B1.

[0079] Step S200: Drive the first shaping head 111 to rotate the first segment A1 toward the second shaping surface 32 along the first direction so that the clamping pair 14 clamps the first segment A1.

[0080] Specifically, the first shaping head 111 rotates 150° and forms a clamping pair 14 with the second shaping head 121. The first shaping head 111 has a first shaping surface 31, and the second shaping head 121 has a second shaping surface 32 and a third shaping surface 33. The second shaping surface 32 and the third shaping surface 33 are connected to form a shaping flange 34.

[0081] Step S300: Drive the clamping pair 14 close to the mounting surface B1 so that the second segment A2 is located between the third forming surface 33 and the mounting surface B1, and the first bent segment A31 is wrapped around the forming flange 34.

[0082] Specifically, the flexible strip A includes a first segment A1, a first curved segment A31, and a second segment A2 connected in sequence. The clamping pair 14 moves toward the mounting surface B1 to pull the flexible strip A, causing the flexible strip A to deform. During this process, the flexible strip A is connected to the body B.

[0083] Furthermore, step S300 also includes: Step S310: Drive the third shaping head 131 closer to the second shaping head 121 so that the forming flange 34 engages with the forming groove 35 to press against the first bent section A31. The forming groove 35 is provided on the third shaping head 131.

[0084] Step S320: Drive the third shaping head 131 away from the second shaping head 121. In this step, the third shaping head 131 is used so that the shape of the first curved segment A31 can still be maintained after the second shaping head 121 separates from the flexible belt A.

[0085] Step S300 includes, for example: Figure 15 As shown, the second protective film affixed to the second adhesive layer C2 is peeled off. The second adhesive layer C2 is adhered to the side of the second segment A2 opposite to the second shaping head 121.

[0086] Step S400: Drive the clamping pair 14 so that the third forming surface 33 presses against the second segment A2 against the mounting surface B1. In this step, the clamping pair 14 maintains the clamping state of the first segment A1.

[0087] Step S500: Drive the first shaping head 111 to rotate in the second direction, so as to move the first segment A1 away from the second shaping head 121. Wherein, the first direction is opposite to the second direction.

[0088] Optionally, the included angle between the second forming surface 32 and the third forming surface 33 is 30 degrees. The third forming surface 33 is parallel to the inner edge of the middle frame. The first shaping head 111 rotates 120° in the opposite direction (along the second direction) so that the first segment A1 avoids the second shaping head 121.

[0089] Step S600: Drive the second shaping head 121 away from the first shaping head 111.

[0090] Step S600 is followed by: removing the first protective film affixed to the first adhesive layer C1. The first adhesive layer C1 is adhered to the side of the first segment A1 opposite to the first shaping head 111. Removing the first protective film in this step prevents the first adhesive layer C1 from adhering to the second shaping head 121.

[0091] Optionally, the first and second protective films are release paper. The first adhesive layer C1 and the second adhesive layer C2 are double-sided adhesive.

[0092] Step S700: Drive the first shaping head 111 to rotate again along the first direction. For example, drive the first shaping head 111 to move to a position relative to the mounting surface B1.

[0093] Step S800: Drive the second forming surface 32 to press the first segment A1 against the second segment A2.

[0094] Optionally, the first shaping head 111 rotates 180° in the first direction, so that the first segment A1 just comes into contact with the second segment A2, thereby fixing the first segment A1 and the second segment A2 together. This reduces the difficulty of driving the first shaping head 111, and further avoids the first shaping head 111 pulling on the second segment A2.

[0095] Preferably, the first forming surface 31 is located between the first curved section A31 and the second curved section A32 to avoid squeezing the first curved section A31 and the second curved section A32.

[0096] Furthermore, the flexible strip bending method also includes: driving the forming base plate 132 of the third forming part 13 to move with the clamping pair 14 so that after the flexible strip A is bent, the first segment A1 and the second segment A2 are at the same height.

[0097] In summary, the flexible strip bending method in this embodiment has a first forming surface 31 on the first forming head 111, and a second forming surface 32 and a third forming surface 33 on the second forming head 121. The first forming head 111 and the second forming head 121 form a clamping pair 14 through the first forming surface 31 and the second forming surface 32. The second forming surface 32 and the third forming surface 33 are connected to form a forming flange 34. Thus, the clamping pair 14 clamps the first segment A1 to pull the flexible strip A, so that during the pre-bending process, the mounting surface B1 of the flexible strip A can face the first segment A1 and the second segment A2, and the first bent segment A31 is wrapped around the forming flange 34. Therefore, during the pressing process, the second forming head 121 and the first forming head 111 press the second segment A2 and the first segment A1 respectively, realizing the bending operation of the first bent segment A31 and improving the morphological accuracy of the flexible strip A after bending. On the other hand, the first shaping head 111 and the second shaping head 121 can be used together to pull the flexible band A, or used separately to allow the first shaping head 111 to independently bend the first segment A1. Thus, when the flexible band A and the body B are connected, the bending assembly 1 can operate in a smaller space and reduce the pulling on the connection point between the flexible band A and the body B.

[0098] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
