[0002] Flexible circuit boards are favored for their excellent properties such as light weight, thinness, and ability to be bent and folded freely, and are widely used in the electronics field.

[0003] Most of the flexible circuit boards in RIM products are stacked. When bending these stacked flexible circuit boards, the upper circuit board needs to be flipped up so that it does not interfere with the bending operation of the lower circuit board.

[0004] However, existing bending mechanisms cannot guarantee the upward flip position of flexible circuit boards stacked on top of each other in RIM products, and there are cases where the upward flip position is deviated from the required position. Furthermore, bending the circuit board located on the lower side will increase the risk of interference to the circuit board located on the upper side, thus limiting their effectiveness.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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 mechanical connection or an electrical connection; 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 application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] See Figure 1 and Figure 2 One embodiment of this application provides a bending mechanism, including a housing assembly 1, a bending assembly 2, and an auxiliary assembly 3. The housing assembly 1 can accommodate the bending assembly 2 and the auxiliary assembly 3, so as to shield and protect them while combining them. Specifically, the housing assembly 1 has a receiving cavity inside, and the bending assembly 2 and the auxiliary assembly 3 are partially or entirely located within the receiving cavity.

[0041] The bending assembly 2 is used to bend the circuit board. Specifically, the bending assembly 2 includes a drive member 21 and a bending head 22. The drive member 21 is disposed on the housing assembly 1, and the bending head 22 is disposed on the drive member 21. Driven by the drive member 21, the bending head 22 moves from a first position to a second position. During the movement, the bending head 22 can push the circuit board, causing the circuit board to bend and flip upwards. When the bending head 22 moves to the second position, the circuit board is bent to a specified angle. Specifically, the bending head 22 has a push plate extending along its own moving direction. During the movement, the bending head 22 can push the circuit board through the push plate, causing the circuit board to bend and flip upwards. It is understood that in the embodiments of this application, the push plate is a flat plate. In other embodiments not shown, the push plate is an annular plate, an arc-shaped plate, or two or more flat plates.

[0042] The auxiliary component 3 is used to assist the bending component 2 in positioning and resetting operations. Specifically, the auxiliary component 3 includes a positioning member 31. The housing component 1 has a positioning part 14. The positioning member 31 is disposed on the bending component 2. When the bending head 22 moves to the second position, it is detachably connected to the positioning part 14, so that the positioning member 31 can position the bending head 22 when it moves to the second position, so that the circuit board that is bent up to a specified angle will not interfere with the bending operation of other circuit boards located below it.

[0043] The auxiliary component 3 also includes a reset member 32. The two ends of the reset member 32 in the elastic direction are connected to the outer shell component 1 and the bending component 2, respectively. When the positioning member 31 leaves the positioning part 14, it moves the bending head 22 to the first position, thus completing the reset of the bending head 22. Specifically, in the embodiments of this application, the reset member 32 is an elastic member. When the bending head 22 moves from the first position to the second position under the drive of the driving member 21, the reset member 32 deforms and generates compressive or tensile force. When the positioning member 31 leaves the positioning part 14, the reset member 32 can gradually recover and drive the bending head 22 back to the first position, thereby completing the reset.

[0044] In summary, when using the bending mechanism of this application, the outer casing assembly 1 can be installed on the processing device first, and the bending head 22 can be positioned directly opposite the part of the circuit board that needs to be bent. Then, the bending head 22 is driven by the driving member 21 to move from the first position to the second position, so that the bending head 22 can push the circuit board and bend it upward to a specified angle. The positioning member 31 can position the bending head 22 when it moves to the second position, so that the circuit board will not interfere with the bending operation of other circuit boards located below it. After the other circuit boards located below have completed the bending operation, the positioning member 31 can be controlled to leave the positioning part 14, so that the reset member 32 can drive the bending head 22 back to the first position to complete the reset for the next use.

[0045] See Figure 1 and Figure 3 To make the bending mechanism of this application applicable to various processing devices, in one embodiment, the bending head 22 and the drive member 21 are detachably connected. The user can replace the bending head 22 to make the bending mechanism applicable to other processing devices.

[0046] Specifically, in one embodiment, the driving member 21 is provided with a fixing part, and the bending head 22 is threadedly connected to the fixing part, so that the bending head 22 and the driving member 21 are detachable. In another embodiment, the driving member 21 is provided with a fixing part, and the bending head 22 is snap-fitted to the fixing part, so that the bending head 22 and the driving member 21 are detachable.

[0047] See Figures 1-3To ensure that the bending head 22 is detachably connected to the positioning part 14 when it moves to the second position, in one embodiment, the positioning member 31 has a positioning head on its side opposite to the bending assembly 2, and the positioning part 14 is a positioning port. The positioning head can be inserted into the positioning port when the bending head 22 moves to the second position to position the bending head 22 on the housing assembly 1. Specifically, the positioning member 31 also has an elastic member, and the positioning head is connected to the bending assembly 2 through the elastic member so that the positioning head can be inserted into the positioning port under the elastic force of the elastic member, and can be removed from the positioning port by the operator pushing the positioning head to compress the elastic member, so as to reset the bending head 22.

[0048] That is, during the process of the driving member 21 driving the bending head 22 from the first position to the second position, the positioning member 31 can move with the bending head 22, and when it moves to the positioning port, it is inserted into the positioning port under the action of the elastic member, so as to achieve the positioning of the bending head 22 on the housing assembly 1. When it is necessary to reset the bending head 22, the positioning head can be pushed to move it out of the positioning port, so that the bending head 22 moves back to the first position under the action of the reset member 32, thus completing the reset.

[0049] See Figure 1 and Figure 3 To facilitate the replacement of the drive member 21 and the reset member 32, in one embodiment, one end of the reset member 32 in the elastic direction is detachably connected to the housing assembly 1, the other end of the reset member 32 in the elastic direction is detachably connected to the bending assembly 2, and the drive member 21 is detachably connected to the housing assembly 1.

[0050] Specifically, the reset member 32 is a spring, the driving member 21 has an abutment portion, the reset member 32 is sleeved on the driving member 21, and the two ends of the reset member 32 in the elastic direction abut against the housing assembly 1 and the abutment portion, respectively. When the driving member 21 and / or the reset member 32 reach the end of their service life, they can be replaced by removing the driving member 21 from the housing assembly 1 and removing the reset member 32 from both the housing assembly 1 and the driving member 21.

[0051] To ensure that the housing assembly 1 provides good shielding and protection for the drive member 21 while also having a large contact area between the drive member 21 and the housing assembly 1, thus ensuring the stability of the drive member 21 on the housing assembly 1, in one embodiment, the drive member 21 is mounted through the housing assembly 1.

[0052] Specifically, the outer casing assembly 1 has a first opening and a second opening on two opposite sides, and the driving member 21 has a first end and a second end opposite to each other. The driving member 21 is located inside the outer casing assembly 1, and the first end of the driving member 21 passes through the first opening and is connected to the bending head 22, while the second end of the driving member 21 is located inside the second opening. When it is necessary to move the bending head 22 to a second position by driving the driving member 21, the second end can be pushed through the second opening, causing the first end to drive the bending head 22 to move.

[0053] See Figure 1 and Figure 3 In order to facilitate the fixing of the drive member 21 that is mounted on the housing assembly 1 and to facilitate the drive member 21 to push the bending head 22, in one embodiment, the drive member 21 is a bearing.

[0054] Specifically, the drive member 21 has a bearing portion 211 and a moving rod 212. The bearing portion 211 is fixed inside the housing assembly 1, and the moving rod 212 is slidably connected to the bearing portion 211. Both the first end and the second end are located on the moving rod 212. When the second end is pushed through the second port, the moving rod 212 can slide on the bearing portion 211, thereby causing the first end to drive the bending head 22 to move.

[0055] To facilitate the replacement of the drive member 21 with the selected bearing and the return member 32 with the selected spring, in one embodiment, the housing assembly 1 includes a first housing 11 and a second housing 12. The second housing 12 is detachably mounted on the first housing 11. The bearing portion 211 of the drive member 21 is disposed inside the first housing 11 and abuts against the second housing 12. By removing the second housing 12 from the first housing 11, the drive member 21 can be removed from inside the first housing 11, thereby enabling the removal and replacement of the bearing and spring.

[0056] Specifically, the first housing 11 has a channel for mounting the drive component 21, and the bearing portion 211 and part of the moving rod 212 of the drive component 21 are located in the channel. The second housing 12 is fixed to the first housing 11 by bolts and abuts against the bearing portion 211 of the drive component 21 to support the bearing portion 211.

[0057] The first housing 11 also has a positioning plate 13, which is detachably mounted on the side of the first housing 11 opposite to the second housing 12. The moving rod 212 of the driving member 21 passes through the positioning plate 13 and has an abutment portion. The two ends of the resetting member 32 in the elastic direction abut against the positioning plate 13 and the abutment portion, respectively, to cooperate with the second housing 12 to fix the driving member 21. Specifically, the resetting member 32, which is a spring, is sleeved on the moving rod 212, and one end of the spring in the elastic direction abuts against the bearing portion 211, while the other end in the elastic direction abuts against the inner side wall of the first housing 11 or the positioning plate 13.

[0058] For further details, please refer to [link / reference]. Figure 1 and Figure 2 The positioning plate 13 is fixed to the first housing 11 by bolts and is spaced apart from the bending head 22 along the moving direction of the bending head 22 to provide space for the bending head 22 to move and be fixed. The positioning plate 13 is provided with a through groove 15 with the opening direction perpendicular to the moving direction of the bending head 22. The through groove 15 passes through the positioning plate 13 along the moving direction of the bending head 22 so that the moving rod 212 can pass through the through groove 15 and be mounted on the positioning plate 13.

[0059] See Figure 1 and Figure 4 To facilitate the placement of products that need to be bent, in one embodiment, the bending mechanism further includes a product carrier 4. The product carrier 4 has a first product receiving slot 41 and a second product receiving slot 42 for placing different products, and a through opening 43 extending along the moving direction of the bending head 22. The housing assembly 1 and the through opening 43 are spaced apart along the moving direction of the bending head 22, so that the bending head 22 can move up and down through the through opening 43 during the process of the driving member 21 driving the bending head 22 from a first position to a second position.

[0060] Both the first product receiving groove 41 and the second product receiving groove 42 are connected to the through opening, so that when a product is placed in the first product receiving groove 41 or the second product receiving groove 42, part of the product can be located in the through opening, so that the bending head 22 of the bending mechanism can be directly facing the part of the product that needs to be bent, so as to bend the part of the product that needs to be bent upward to the specified angle.

[0061] Specifically, the product carrier 4 is provided with a first connecting port that connects the first product receiving slot 41 and the through port 43, and the through direction of the first connecting port is perpendicular to the moving direction of the bending head 22. When a product is placed in the first product receiving slot 41, part of the product can pass through the first connecting port and be located in the through port. The product carrier 4 is provided with a second connecting port that connects the second product receiving slot 42 and the through port 43, and the through direction of the second connecting port is perpendicular to the moving direction of the bending head 22. When a product is placed in the second product receiving slot 42, part of the product can pass through the second connecting port and be located in the through port 43. In one embodiment, the product carrier 4 includes a support platform 44 and a support plate 45, and the through port 43 is disposed on the support plate 45. The outer shell assembly 1 and the support plate 45 are both disposed on the support platform 44. This structure facilitates the provision of the through port 43 on the product carrier 4, and also facilitates that after the outer shell assembly 1 is disposed on the product carrier 4, the bending head 22 can be located below the through port 43 or inside the through port 43.

[0062] Specifically, in the embodiments of this application, the support plate 45 has a first surface and a second surface that are opposite to each other along the moving direction of the bending head 22. The support platform 45 is disposed on the first surface, and the opening of the first product receiving groove 41 is located on the second surface so that the operator can place the product into the first product receiving groove 41. The opening of the second product receiving groove 42 is located on the second surface so that the operator can place the product into the second product receiving groove 42.

[0063] In summary, when using the processing apparatus of this application, the first product is placed in the first product receiving slot 41 of the product carrier 4, with a portion of the product passing through the first connecting opening and located within the through opening. Then, the second product is placed in the second product receiving slot 42 of the product carrier 4, with a portion of the product passing through the second connecting opening and located within the through opening. At this time, the portion of the second product located within the through opening is above the portion of the first product located within the through opening, and the bending head 22 can be directly aligned with the part of the second product that needs to be bent. Then, the driving member 21 drives the bending head 22 from the first position to the second position, so that the bending head 22 can push the second product, allowing the second product to be bent upwards to a specified angle. The positioning member 31 positions the bending head 22 when it moves to the second position, ensuring that the product does not interfere with the bending operation of the first product and guaranteeing the effectiveness of use. After the first product located on the lower side completes the bending operation, the positioning member 31 can be controlled to leave the positioning part 14, causing the reset member 32 to move the bending head 22 back to the first position, completing the reset for the next use.

[0064] As can be understood, in the embodiments of this application, both the first product and the second product are circuit boards, and both the first product and the second product are located on the same component. The first product receiving slot 41 and the second product receiving slot 41 are connected, and the circuit board having the first product and the second product can be placed in the connected first product receiving slot 41 and the second product receiving slot 41 so that the first product and the second product can be located in the first product receiving slot 41 and the second product receiving slot 41 simultaneously.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
