Technical Field

[0001] This application relates to the field of FPC bending technology, and more particularly to an automatic bending structure for FPC and an FPC bending device. Background Technology

[0002] FPC, also known as flexible circuit board or flexible circuit board, is highly favored for its excellent characteristics such as light weight, thinness, and ability to be bent and folded freely.

[0003] However, most FPC bending is currently done manually by workers. After working for a period of time, workers become fatigued, which can lead to a decrease in bending yield or even failure to meet requirements.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0005] This application provides an automatic bending structure for FPC and a bending device for FPC to solve the above-mentioned problems.

[0006] In a first aspect, this application provides an automatic bending structure for an FPC, including a first bending fixture. The first bending fixture includes a pusher and a first power mechanism. The first power mechanism drives the pusher to move vertically and upward to bend the FPC at a 90° angle. The first bending fixture also includes an arc forming needle mechanism. The first power mechanism includes a first power group and a second power group. The second power group is connected to the first power group and the pusher. The first power group drives the second power group and the pusher to move vertically, and the second power group drives the pusher to move horizontally. The FPC includes a bending area, and the arc forming needle mechanism partially extends into the bending area. Above, the first power unit drives the pusher to move vertically upwards to bend the FPC by 90°, while the arc forming needle mechanism located in the bending area moves vertically downwards. The second power unit drives the pusher to move horizontally to bend the FPC portion after bending by 90° by 90° in the horizontal direction. The arc forming needle mechanism includes an arc forming needle, a first moving cylinder, and a second moving cylinder. The second moving cylinder is connected to the first moving cylinder and the arc forming needle. The first moving cylinder drives the second moving cylinder and the arc forming needle to move toward or away from the bending area. The second moving cylinder drives the arc forming needle to move toward or away from the FPC, and the movement directions of the first moving cylinder and the second moving cylinder are perpendicular.

[0007] Optionally, it also includes a second bending fixture, wherein the FPC includes a first bending area and a second bending area, and after the first bending fixture bends the first bending area of ​​the FPC by 90°, the second bending fixture bends the second bending area of ​​the FPC by 90°.

[0008] Optionally, the second bending fixture includes a bending component, a fixed platform, and a bending cylinder. The bending cylinder is connected to the fixed platform, and the output end of the bending cylinder is connected to the bending component. The bending cylinder drives the bending component to move to the second bending area and drives the bending component to move upward in the vertical direction to bend the second bending area of ​​the FPC by 90°.

[0009] Optionally, the second bending fixture further includes a stop member connected to a fixed platform. The stop member is located at one end of the bending member, and when the bending member bends the FPC, the stop member at the other end of the FPC stops a portion of the FPC.

[0010] Secondly, this application also provides a bending device for FPC, which includes the aforementioned automatic bending structure for FPC.

[0011] Optionally, the bending device for the FPC further includes a positioning fixture, in which the product and the FPC connected to the product are located, and the automatic bending structure of the FPC bends the PFC located in the positioning fixture.

[0013] This embodiment of the application sets up a first bending fixture, which causes the pusher to bend the FPC by 90° under the action of the first power mechanism. This greatly improves the automation of FPC bending, reduces the workload of workers, and reduces the possibility of a decrease in bending yield due to fatigue from long hours of work. This is beneficial to improving the bending efficiency and yield of FPC. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0028] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0029] To address the technical problems in the prior art, this application provides an automatic bending structure and bending equipment for FPC. By setting a first bending fixture, the pushing component bends the FPC by 90° under the action of a first power mechanism, which greatly improves the automation level of FPC bending, reduces the workload of workers, and reduces the possibility of decreased bending yield due to fatigue from long-term work. This is beneficial to improving the bending efficiency and yield of FPC.

[0030] Figure 1-3 An FPC bending device provided in this application embodiment is used to bend an FPC2 connected to a product 1, such as... Figure 5 It includes a frame 3, a feeding unit 4, a robotic arm assembly 5, an operating table 6, a positioning fixture 7, a double-sided adhesive feeding and peeling mechanism 8, and an automatic bending structure 9 for the FPC. The operating table 6 is located on the frame 3. The feeding unit 4, the robotic arm assembly 5, and the double-sided adhesive feeding and peeling mechanism 8 are located on the frame 3 and around the operating table 6. The product 1 and the FPC 2 connected to the product 1 are located at the feeding unit 4. The robotic arm assembly 5 holds the product 1 and the FPC 2 connected to the product 1 at the feeding unit 4. FPC2 is moved onto positioning fixture 7, which is located on operating table 6. Positioning fixture 7 corrects the position of product 1. Double-sided adhesive feeding and peeling mechanism 8 provides double-sided adhesive and peels the film off one side of it before being moved by robotic arm group 5 to be bonded to product 1. Robotic arm group 5 peels the film off the other side of the double-sided adhesive bonded to product 1. Automatic bending structure 9 of FPC 2 bends FPC2 and bonds one end of FPC2 to the peeled double-sided adhesive. Positioning fixture 7 corrects the position of product 1 and FPC2 connected to product 1, making it convenient for robotic arm group 5 to apply double-sided adhesive to FPC2 and for automatic bending structure 9 of FPC to perform bending operations. The setting of feeding unit 4 facilitates the large-scale operation of this equipment and provides a prerequisite for improving bending efficiency in the future. Product 1 of this application is a square mobile phone camera module, including but not limited to this.

[0031] In this application, by setting up a robotic arm group 5, a positioning fixture 7, a double-sided adhesive glass feeding mechanism, and an automatic bending structure 9 for FPC, the fully automatic gluing and bending of FPC2 is achieved. Compared with the manual method, it has a higher degree of automation and higher production efficiency. It is also less likely to experience a decline in yield after long-term operation, reducing the workload of the staff and allowing them to concentrate on maintaining the machine and monitoring the bending yield.

[0032] Preferably, the operating table 6 is a rotatable frustum, and multiple positioning fixtures 7 are evenly distributed on the outer periphery of the operating table 6. By rotating the operating table 6, the robot arm group 5 can sequentially place the product 1 into the positioning fixture 7. Through rotation, the positioning fixture 7 can also move closer to the next operating position, which is rhythmic. Each rotation of the operating table 6 moves the FPC2 closer to an operating position. When the FPC2 moves to the next operating position, the corresponding adhesive application, bending, inspection, and transfer operations are performed on the FPC2, which helps to improve work efficiency and facilitates the handling of the robot arm group 5. The robot arm group 5 only needs to move a short distance to realize the feeding of the positioning fixture 7 and quickly apply the double-sided adhesive at the double-sided adhesive feeding and peeling mechanism 8 to the FPC2 located at the positioning fixture 7. At the same time, since the positioning fixture 7 can move to the automatic bending structure 9 of the FPC, it also facilitates the bending operation of the FPC2 by the automatic bending structure 9 of the FPC.

[0033] Furthermore, it also includes an inspection mechanism 10, a receiving section 11, and an NG material station 12. The inspection mechanism 10 inspects the product 1 after bending and bonding double-sided tape and the FPC2 connected to the product 1. The robotic arm group 5 moves the product 1 and the FPC2 connected to the product 1 that fail the inspection by the inspection mechanism 10 to the NG material station 12, and moves the product 1 and the FPC2 connected to the product 1 that pass the inspection to the receiving section 11.

[0034] In this application, the testing agency 10 inspects the product 1 after bending and applying double-sided tape, as well as the FPC2 connected to the product 1, to remove unqualified product 1 and FPC2 connected to the product 1. Unqualified product 1 and FPC2 connected to the product 1 are moved to the NG material station 12 by the robotic arm group 5, while qualified product 1 and FPC2 connected to the product 1 are moved to the receiving section 11 for subsequent operations. By detecting and placing unqualified product 1 and FPC2 connected to the product 1 in a dedicated recycling location, the mixing and indistinguishability of unqualified product 1 and FPC2 connected to the product 1 with qualified product 1 and FPC2 connected to the product 1, thus avoiding impacting the yield of subsequent processes, is prevented.

[0035] Furthermore, the positioning fixture 7 includes a fixture base 13, a first elastic stop 14, and a second elastic stop 15. The fixture base 13 includes a base 16 and a first baffle 17 and a second baffle 18 perpendicular to each other. The first baffle 17 and the second baffle 18 are disposed on the base 16. The first elastic stop 14 and the second elastic stop 15 are respectively the opposite ends of the first baffle 17 and the second baffle 18. When the product 1 is located on the base 16, the first elastic stop 14 stops the product 1 so that both ends of the product 1 are in contact with the first elastic stop 14 and the first baffle 17, respectively. The second elastic stop 15 stops the product 1 so that both ends of the product 1 are in contact with the second elastic stop 15 and the second baffle 18, respectively.

[0036] In this application, the product 1 is blocked in two vertical directions by the first elastic blocking member 14 and the second elastic blocking member 15, so that the product 1 will not be crushed due to excessive force while clamping the product 1.

[0037] Furthermore, it also includes a film paper recycling box 19, which is located at one end of the double-sided adhesive feeding and peeling mechanism 8. The robotic arm group 5 will move the film paper peeled from the double-sided adhesive to the film paper recycling box 19 for recycling.

[0038] In this application, the membrane paper recycling box 19 is designed to prevent membrane paper from being scattered in the equipment due to lack of recycling, which could lead to equipment jamming and contamination.

[0039] Furthermore, the robotic arm assembly 5 includes a loading robotic arm 20, a film-applying robotic arm 21, and a unloading robotic arm 22. The loading robotic arm 20 moves the product 1 and the FPC2 connected to the product 1 onto the positioning fixture 7. The film-applying and film-removing robotic arm moves the double-sided adhesive tape with one side peeled off to the product 1 for bonding, and peels off the other side of the bonded double-sided adhesive tape. The unloading robotic arm 22 moves the product 1 and the FPC2 connected to the product 1 to the receiving section 11 or the NG material station 12.

[0040] It is understood that this application also includes a vision device (not labeled) to cooperate with the robotic arm group 5 to remove the product 1 and the FPC2 connected to the product 1, remove the double-sided adhesive, and remove the film paper, etc.

[0041] Furthermore, the automatic bending structure 9 of the FPC includes a first bending fixture 23, which bends the FPC2 and bonds one end of the FPC2 to the double-sided adhesive after the film is peeled off. Specifically, the first bending fixture 23 includes a pusher 24 and a first power mechanism 25. The first power mechanism 25 includes a first power group 26 and a second power group 27. The second power group 27 is connected to the first power group 26 and the pusher 24. The first power group 26 drives the second power group 27 and the pusher 24 to move vertically. The second power group 27 drives the pusher 24 to move horizontally. The first power group 26 drives the pusher 24 to move vertically and upward to bend the FPC2 by 90°. The second power group 27 drives the pusher 24 to move horizontally to bend the 90° bent portion of the FPC2 by 90° and bond one end of the FPC2 to the double-sided adhesive. The first power group 26 and the second power group 27 are powered by cylinders.

[0042] In this application, the first bending fixture 23 enables the FPC2 to be bent at 90° in the vertical direction and then bent at 90° in the horizontal direction, thus realizing the automated bending process of the FPC2 and improving the bending efficiency of the FPC2.

[0043] Furthermore, the first bending fixture 23 also includes an arc forming needle 30 mechanism 28. The FPC2 includes a bending area 29. The arc forming needle 30 mechanism 28 extends into the bending area 29. The first power unit 26 drives the pusher 24 to move vertically and upward to bend the FPC2 by 90°. At the same time, the arc forming needle 30 mechanism 28 located in the bending area 29 moves vertically and downward. The second power unit 27 drives the pusher 24 to move horizontally to bend the 90° bent FPC2 part horizontally by 90°. The arc-forming needle 30 mechanism 28 performs a downward pull operation on the bending area 29 of the FPC2, causing the bending area 29 to form an arc shape after bending. This shape helps to reduce the presence of a sharp transition surface on the FPC2, thus reducing the possibility of structural damage at that location. It can be understood that the downward pull of the arc-forming needle 30 mechanism 28 is relatively small, only aimed at forming the arc shape of the bending area 29, therefore its impact on the bending operation of the second power unit 27 is minimal. The specific inspection content of the inspection mechanism 10 includes the integrity of the connection between the FPC2 and the double-sided adhesive and whether the bending area 29 is arc-shaped after bending.

[0044] The arc forming needle 30 mechanism 28 includes an arc forming needle 30, a first moving cylinder 31, and a second moving cylinder 32. The second moving cylinder 32 is connected to the first moving cylinder 31 and the arc forming needle 30. The first moving cylinder 31 drives the second moving cylinder 32 and the arc forming needle 30 to move toward or away from the bending area 29. The second moving cylinder 32 drives the arc forming needle 30 to move toward or away from the FPC2, and the movement directions of the first moving cylinder 31 and the second moving cylinder 32 are perpendicular.

[0045] Further, please refer to Figure 4 , Figure 6 As a variation of the automatic bending structure 9 for FPC, the automatic bending structure 40 for FPC includes a first bending fixture 41 and a second bending fixture 42. The first bending fixture 41 bends the FPC 43 at an angle A in a first direction, and the second bending fixture 42 bends the FPC 43 at an angle B in a second direction, then bonds one end of the FPC 43 to the double-sided adhesive after the film has been removed. Specifically, the FPC 43 includes a first bending area 44 and a second bending area 45. After the first bending fixture 41 bends the first bending area 44 of the FPC 43 by 90°, the second bending fixture 42 bends the second bending area 45 of the FPC 43 by 90°, and then a robotic arm attaches one end of the FPC 43 to the double-sided adhesive after the film has been removed. At this time, the bending of the FPC43 with two areas that need to be bent can be achieved by the first bending fixture 41 and the second bending fixture 42. In addition to this, bending fixtures can also be added to achieve bending of the FPC43 with more bending areas.

[0046] In this modified embodiment, the first bending fixture 41 further includes a pusher 46, a first power mechanism 47, and an arc forming needle mechanism 48. The first power mechanism 47 includes a first power group 49, which drives the pusher 46 to move in the vertical direction. The arc forming needle mechanism 48 extends partially above the first bending area 44. While the first power group 49 drives the pusher 46 to move vertically upward to bend the FPC 43 by 90°, the arc forming needle mechanism 48 located in the bending area moves vertically downward. Specifically, the arc forming needle mechanism 48 includes an arc forming needle 50, a first moving cylinder 51, and a second moving cylinder 52. The second moving cylinder 52 is connected to both the first moving cylinder 51 and the arc forming needle 50. The first moving cylinder 51 drives the second moving cylinder 52 and the arc forming needle 50 to move toward or away from the first bending area 44. The second moving cylinder 52 drives the arc forming needle 50 to move toward or away from the FPC 43, and the movement directions of the first moving cylinder 51 and the second moving cylinder 52 are perpendicular. The arrangement of the first moving cylinder 51 and the second moving cylinder 52 is used to move the arc forming needle 50 closer to or away from the FPC 43, and also to avoid collisions between the FPC 43 and the arc forming needle mechanism 48 when the FPC 43 moves with the operating table.

[0047] In this modified embodiment, the second bending fixture 42 includes a bending member 53, a fixed platform 54, a bending cylinder 55, and an abutment member 56. The bending cylinder 55 is connected to the fixed platform 54, and the output end of the bending cylinder 55 is connected to the bending member 53. The bending cylinder 55 drives the bending member 53 to move to the second bending area 45 and drives the bending member 53 to move vertically upward to bend the second bending area 45 of the FPC 43 by 90°. The abutment member 56 is connected to the fixed platform 54 and is located at one end of the bending member 53. When the bending member 53 bends the FPC 43, the abutment member 56 located at the other end of the FPC 43 blocks part of the FPC 43. The bending component 53, the fixed platform 54, the bending cylinder 55, and the abutment component 56 enable the second bending of the FPC43. The abutment component 56 provides support and can effectively prevent deformation of the FPC43 except for the second bending area 45, which helps to ensure the bending effect.
