Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board processing technology, and specifically to a flexible circuit board bending device. Background Technology

[0002] Electronic devices typically incorporate flexible printed circuits (FPCs), such as those found in electronic pens. These FPCs usually need to be bent into the required shapes. Currently, there is no dedicated equipment for bending the FPCs in electronic pens; they must be bent manually before assembly. This process makes it difficult to effectively control the bending shape and effect, and the inconvenience results in low production efficiency. Utility Model Content

[0003] In view of this, the present invention provides a flexible circuit board bending device to solve the problems of ineffective control of the bending shape and bending effect of flexible circuit boards and low production efficiency.

[0004] This utility model provides a flexible circuit board bending device, comprising: a base; a support assembly disposed on the base and having a support surface and a bending opening, the bending opening being through the support surface, the support surface being used to place the flexible circuit board; a pressing assembly disposed on the base and including a pressing member and a bending member, both the pressing member and the bending member being movable relative to the support surface, the pressing member being able to abut against the support surface, and the bending member being able to be inserted into the bending opening; and a rotating assembly disposed on the base and including a rotating part, the rotating part being rotatable relative to the support surface, used to bend at least a portion of the flexible circuit board extending beyond the support surface.

[0005] Beneficial effects: This utility model's flexible circuit board bending equipment uses a pressing component to press the flexible circuit board firmly against a supporting surface, a bending component to press a portion of the flexible circuit board into the bending opening, and a rotating component to bend at least the portion of the flexible circuit board extending beyond the supporting surface. The pressing component prevents misalignment of the flexible circuit board, ensuring bending accuracy. The bending component and rotating component can bend different positions of the flexible circuit board, and different bending methods can be used for different positions according to bending requirements, resulting in different shapes. The bending method and shape are more flexible, effectively controlling the bending shape and effect of the flexible circuit board, ensuring high bending consistency, convenient operation, and improved production efficiency.

[0006] In one optional embodiment, the pressing component includes: a first driver disposed on the base and connected to the pressing member, for driving the pressing member to move relative to the support surface; and a second driver connected to the first driver and the bending member, for driving the bending member to move relative to the support surface, wherein the first driver drives the second driver to move relative to the support surface.

[0007] Beneficial effects: On the one hand, it can ensure that the bending component can bend the flexible circuit board only after the pressing component presses it tightly, so that the positioning of the flexible circuit board is reliable and the bending consistency is high. On the other hand, while the first driver drives the pressing component to approach the support surface, it also drives the second driver to approach the support surface. The bending component will approach the support surface with the second driver. When the second driver drives the bending component to bend the flexible circuit board in the future, the extension length required by the second driver is smaller, which reduces the extension stroke of the second driver.

[0008] In one optional embodiment, the pressing assembly further includes: a first mounting plate, on which the first driver is mounted; a guide post connected between the first mounting plate and the base; a sliding member slidably disposed on the guide post; and a second mounting plate disposed between the first mounting plate and the base, and connected to the first driver and the sliding member, wherein the first driver drives the sliding member to slide along the guide post via the second mounting plate, and the second driver and the pressing member are mounted on the second mounting plate.

[0009] Beneficial effects: By setting the first mounting plate, the second mounting plate, and the guide post, the relative positions between the pressing member, the first driver, the second driver, and the base can be defined. Furthermore, the sliding member improves the moving accuracy and smoothness of the second mounting plate.

[0010] In one optional embodiment, the pressing assembly further includes: a first positioning arm and a second positioning arm, both connected to the pressing member, with a positioning gap defined between the first positioning arm and the second positioning arm, the positioning gap being used to position the flexible circuit board; wherein, the rotating part is disposed on one side of the support surface in a first direction, the pressing assembly moves along a second direction, the first positioning arm and the second positioning arm are spaced apart along a third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0011] Beneficial effects: As the pressing component gradually approaches the support surface, the first positioning arm and the second positioning arm are located on opposite sides of the flexible circuit board in the third direction, that is, the flexible circuit board enters the positioning gap. Then the pressing component presses on the flexible circuit board. Since the first positioning arm and the second positioning arm are connected to the pressing component, the first positioning arm and the second positioning arm can limit the relative position of the pressing component and the flexible circuit board in the third direction. As a result, the relative position of the bending component and the flexible circuit board in the third direction is more accurate, and the bending consistency is higher.

[0012] In one optional embodiment, at least one of the first positioning arm and the second positioning arm is provided with a limiting portion, the limiting portion being located within the positioning gap, the limiting portion and the pressing member being located on opposite sides of the bending member in the first direction, and the limiting portion and the supporting surface being spaced apart in the third direction.

[0013] Beneficial effect: By setting the limiting part, the position of this part of the flexible circuit board in the second direction can be limited, thus preventing the flexible circuit board from tilting up.

[0014] In one optional embodiment, the rotating assembly further includes: a rotating driver disposed on the base; a rotating shaft connected to the rotating driver, the rotating driver driving the rotating shaft to rotate; wherein the rotating part is disposed on the end face of the rotating shaft away from the rotating driver, and includes a pressing protrusion and a limiting protrusion, the pressing protrusion and the limiting protrusion being connected, the pressing protrusion being used to press the side of the flexible circuit board facing the pressing assembly, and the limiting protrusion being used to engage electrical components on the flexible circuit board.

[0015] Beneficial effects: By setting a rotary driver and a rotary shaft, the pressing protrusions of the rotating part can be driven to press the flexible circuit board to rotate around the rotation axis of the rotary shaft. Furthermore, by setting a limiting protrusion, it can engage with the electrical components on the flexible circuit board to limit the relative position between the flexible circuit board and the rotating part, thereby limiting the relative position between the flexible circuit board and the support surface and improving the bending consistency of the flexible circuit board.

[0016] In one alternative embodiment, the support component is provided with a positioning protrusion, the positioning protrusion and the support surface defining a positioning groove for accommodating the flexible circuit board.

[0017] Beneficial effect: It can limit the relative position of the flexible circuit board and the support assembly in the second direction, and prevent the flexible circuit board from separating from the support surface.

[0018] In one optional embodiment, the pressing member is provided with a positioning notch, and when the pressing member abuts against the support surface, the positioning protrusion is inserted into the positioning notch.

[0019] Beneficial effects: It can achieve precise positioning between the pressing component and the support component. Since both the pressing component and the second driving component are mounted on the second mounting plate, the precise positioning between the pressing component and the support component can also improve the precise positioning between the second driving component and the support component, thereby improving the precise positioning between the bending component and the support component, which is beneficial to improving the bending consistency of the flexible circuit board.

[0020] In one optional embodiment, the support component has a clearance notch on the side facing the pressing component; the support surface includes a first support surface and a second support surface, the first support surface and the second support surface are located on opposite sides of the clearance notch, the bending opening is provided on the first support surface, and the pressing member can abut against the first support surface.

[0021] Beneficial effects: The clearance notch avoids the need for human or robotic arms to place or remove the flexible circuit board from the support assembly. The first and second support surfaces provide more reliable support for the flexible circuit board, preventing it from tilting at the clearance notch due to lack of support. Furthermore, the closer distance between the bend of the flexible circuit board and the pressing element ensures effective positioning and improves bending consistency.

[0022] In one optional embodiment, the flexible circuit board bending device further includes: a channel component, the channel component being disposed on the base and having a negative pressure channel, the support surface having a suction port, one end of the negative pressure channel being connected to the suction port, and the other end of the negative pressure channel being connected to a vacuum generator.

[0023] Beneficial effects: When the vacuum generator is in a vacuum state, the suction port can generate a suction force on the flexible circuit board, avoiding relative displacement between the support component and the flexible circuit board, thereby improving the positioning reliability between the support component and the flexible circuit board.

[0042] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, a flexible circuit board bending device 1 is provided, which includes a base 100, a support component 200, a pressing component 300, and a rotating component 400.

[0044] A support assembly 200 is disposed on the base 100 and has a support surface 210 and a bending opening 213. The bending opening 213 extends through the support surface 210, which is used to place the flexible circuit board 2. A pressing assembly 300 is disposed on the base 100 and includes a pressing member 310 and a bending member 320. Both the pressing member 310 and the bending member 320 are movable relative to the support surface 210. The pressing member 310 can abut against the support surface 210, and the bending member 320 can be inserted into or removed from the bending opening 213. A rotating assembly 400 is disposed on the base 100 and includes a rotating part 410. The rotating part 410 is rotatable relative to the support surface 210 and is used to bend at least a portion of the flexible circuit board 2 that extends out of the support surface 210.

[0045] For example, the base 100 may have a receiving cavity, and the receiving cavity may have a control circuit. The control circuit is connected to the pressing component 300 and the rotating component 400. The base 100 may have a control button 120, which is connected to the control circuit. The operator can use the control button 120 to control the movement of the pressing component 300 relative to the support surface 210, the rotation of the rotating part 410 relative to the support surface 210, and the start and stop of the flexible circuit board bending device 1.

[0046] Furthermore, the flexible circuit board bending equipment 1 can be equipped with sensors and a PLC (Programmable Logic Controller) to detect the position of the pressing component 310 and the bending component 320, and to control the pressing component 310 and the bending component 320 to manage the holding pressure time, thereby realizing visual bending of the flexible circuit board 2.

[0047] The bending process of the flexible circuit board 2 by the flexible circuit board bending equipment 1 is as follows:

[0048] First, place the unbent flexible circuit board 2 (not shown in the figure, at this time the flexible circuit board 2 can be in a straight state or have a small degree of bending) onto the support surface 210.

[0049] Then, control the pressing component 300 to move closer to the support surface 210 so that the pressing component 310 presses the flexible circuit board 2 onto the support surface 210;

[0050] Next, the bending member 320 is pressed against the portion of the flexible circuit board 2 located at the bending opening 213, pressing a portion of the flexible circuit board 2 into the bending opening 213. Since the supporting surfaces 210 on opposite sides of the bending opening 213 support the flexible circuit board 2, the flexible circuit board 2 is approximately bent into a "V" shape (e.g., ...). Figure 8 (as shown);

[0051] Finally, the rotating part 410 is rotated relative to the support surface 210 to bend at least a portion of the flexible circuit board 2 extending out of the support surface 210 (e.g., Figure 9 (As shown).

[0052] It should be noted that the steps in the bending process described above can also be adjusted. For example, after the pressing member 310 presses the flexible circuit board 2 against the support surface 210, the rotating part 410 can be controlled to rotate first, bending at least a portion of the flexible circuit board 2 extending beyond the support surface 210. Then, the bending member 320 can be controlled to press against the portion of the flexible circuit board 2 located at the bending opening 213, pressing a portion of the flexible circuit board 2 into the bending opening 213. In other words, any adjustments and modifications to the steps in the bending process that can be foreseen by those skilled in the art are within the scope of protection of this utility model patent.

[0053] The flexible circuit board bending device 1 of this utility model, by setting a pressing component 300, can drive the pressing component 310 and the bending component 320 to approach or move away from the support surface 210. The pressing component 310 and the bending component 320 can move synchronously or relatively independently, so as to effectively ensure that after the pressing component 310 presses the flexible circuit board 2, the bending component 320 presses a part of the flexible circuit board 2 into the bending opening 213, thereby preventing the flexible circuit board 2 from being misaligned and ensuring bending accuracy.

[0054] The bending component 320 and the rotating part 410 can be bent at different positions of the flexible circuit board 2. Different bending methods can be used at different positions according to bending requirements to bend different positions into different shapes. The bending method and bending shape are more flexible, effectively controlling the bending shape and bending effect of the flexible circuit board 2. The bending consistency is high, and the operation is convenient. It is easy to install the flexible circuit board 2 into the electronic pen, resulting in higher production efficiency.

[0055] Compared to manually bending the flexible circuit board 2, using the flexible circuit board bending equipment 1 to bend the flexible circuit board 2 allows the equipment to apply bending force to the flexible circuit board 2 for a longer period, maintaining the flexible circuit board 2 in its bent shape for longer. It can even bend the flexible circuit board 2 at a larger angle, allowing for the angle to spring back and release stress, thus fully releasing the stress on the flexible circuit board 2. As a result, when the flexible circuit board 2 is installed on the electronic pen holder, it is less likely to move relative to the holder, preventing loosening and ensuring the functional reliability of the electronic pen.

[0056] like Figure 3As shown, in some embodiments, the pressing assembly 300 includes a first driver 330 and a second driver 340. The first driver 330 is disposed on the base 100 and connected to the pressing member 310, and is used to drive the pressing member 310 to move relative to the support surface 210. The second driver 340 is connected to the first driver 330 and the bending member 320, and is used to drive the bending member 320 to move relative to the support surface 210. The first driver 330 drives the second driver 340 to move relative to the support surface 210.

[0057] For example, the first actuator 330 and the second actuator 340 can be cylinders, and the base 100 can be provided with a pneumatic control valve 130. The pneumatic control valve 130 is connected to the air source, the first actuator 330 and the second actuator 340 respectively. The first actuator 330 and the second actuator 340 can be connected to the same pneumatic control valve 130, or the first actuator 330 and the second actuator 340 can be connected to different pneumatic control valves 130.

[0058] Additionally, the base 100 may be equipped with a cylinder status indicator light to display the cylinder status. Furthermore, sensors may be provided on the first driver 330 and the second driver 340 to detect the position and status of the first driver 330 and the second driver 340.

[0059] The first driver 330 can drive the second driver 340 and the pressing member 310 to move closer to or away from the support surface 210 synchronously. The second driver 340 can drive the bending member 320 to move closer to or away from the support surface 210. After the flexible circuit board 2 is placed on the support surface 210, the second driver 340 is in a retracted state so that the bending member 320 moves away from the support surface 210 to the maximum extent. The first driver 330 drives the pressing member 310 to gradually move closer to the support surface 210 until the pressing member 310 presses the flexible circuit board 2 firmly against the support surface 210. Then the second driver 340 drives the bending member 320 to gradually move closer to the support surface 210 until the second driver 340 extends and retracts to a predetermined length.

[0060] By setting the first driver 330 and the second driver 340, on the one hand, it can be ensured that the pressing member 310 can press the flexible circuit board 2 before the bending member 320 can bend the flexible circuit board 2, so that the positioning of the flexible circuit board 2 is reliable and the bending consistency is high. On the other hand, while the first driver 330 drives the pressing member 310 to approach the support surface 210, it also drives the second driver 340 to approach the support surface 210. The bending member 320 will approach the support surface 210 along with the second driver 340. When the second driver 340 drives the bending member 320 to bend the flexible circuit board 2, the extension length required by the second driver 340 is smaller, which reduces the extension stroke of the second driver 340.

[0061] Furthermore, the pressing assembly 300 also includes a first mounting plate 350, a second mounting plate 380, a guide post 360, and a slider 370. A first driver 330 is mounted on the first mounting plate 350, and the guide post 360 is connected between the first mounting plate 350 and the base 100. The slider 370 is slidably sleeved on the guide post 360. The second mounting plate 380 is located between the first mounting plate 350 and the base 100, and is connected to the first driver 330 and the slider 370. The first driver 330 drives the slider 370 to slide along the guide post 360 via the second mounting plate 380. The second driver 340 and the pressing member 310 are mounted on the second mounting plate 380.

[0062] For example, the pressing assembly 300 also includes mounting posts 390, which are connected between the first mounting plate 350 and the base 100. There can be four mounting posts 390, connected to the four apex corners of the first mounting plate 350. Furthermore, there can be two guide posts 360, connected to opposite sides of the first mounting plate 350. The sliding element 370 can be a linear bearing.

[0063] By setting the first mounting plate 350, the second mounting plate 380, and the guide post 360, the relative positions between the pressing member 310, the first driver 330, the second driver 340, and the base 100 can be defined. Furthermore, the sliding member 370 improves the moving accuracy and smoothness of the second mounting plate 380.

[0064] like Figure 4 As shown, in some embodiments, the pressing assembly 300 further includes a first positioning arm 312 and a second positioning arm 313. Both the first positioning arm 312 and the second positioning arm 313 are connected to the pressing member 310. A positioning gap is defined between the first positioning arm 312 and the second positioning arm 313, and the positioning gap is used to position the flexible circuit board 2. The rotating part 410 is disposed on one side of the support surface 210 in the first direction (indicated by arrow A in the figure). The pressing assembly 300 moves along the second direction (indicated by arrow B in the figure). The first positioning arm 312 and the second positioning arm 313 are spaced apart along a third direction (indicated by arrow C in the figure), and the first direction, the second direction, and the third direction are perpendicular to each other.

[0065] As the pressing component 300 gradually approaches the support surface 210, the first positioning arm 312 and the second positioning arm 313 are located on opposite sides of the flexible circuit board 2 in the third direction, that is, the flexible circuit board 2 enters the positioning gap. Then the pressing member 310 presses against the flexible circuit board 2. Since the first positioning arm 312 and the second positioning arm 313 are connected to the pressing member 310, the first positioning arm 312 and the second positioning arm 313 can limit the relative position of the pressing member 310 and the flexible circuit board 2 in the third direction. As a result, the relative position of the bending member 320 and the flexible circuit board 2 in the third direction is more accurately positioned, and the bending consistency is higher.

[0066] Furthermore, at least one of the first positioning arm 312 and the second positioning arm 313 is provided with a limiting part 314, which is located within the positioning gap. The limiting part 314 and the pressing member 310 are located on opposite sides of the bending member 320 in the first direction. The limiting part 314 is spaced apart from the support surface 210 in the third direction and is located on the side of the flexible circuit board 2 away from the support surface 210.

[0067] When the bending member 320 bends the flexible circuit board 2, the portion of the flexible circuit board 2 located in the first direction opposite to the pressing member 310 of the bending member 320 will move. By setting the limiting part 314, the position of this portion of the flexible circuit board 2 in the second direction can be limited, so as to prevent the flexible circuit board 2 from warping and ensure that the shape of the flexible circuit board 2 meets the requirements.

[0068] like Figure 7 As shown, in some embodiments, the rotating assembly 400 further includes a rotating driver 420 and a rotating shaft 430. The rotating driver 420 is disposed on the base 100. The rotating shaft 430 is connected to the rotating driver 420, and the rotating driver 420 drives the rotating shaft 430 to rotate. A rotating part 410 is disposed on the end face of the rotating shaft 430 away from the rotating driver 420, and the rotating part 410 includes a pressing protrusion 411 and a limiting protrusion 412. The pressing protrusion 411 and the limiting protrusion 412 are connected. The pressing protrusion 411 is used to press the side of the flexible circuit board 2 facing the pressing assembly 300, and the limiting protrusion 412 is used to engage electrical components on the flexible circuit board 2.

[0069] For example, the rotary actuator 420 can be an electrically driven rotary structure such as a motor or electric motor, or the rotary actuator 420 can be a pneumatically driven rotary structure.

[0070] By providing a rotary driver 420 and a rotary shaft 430, the pressing protrusion 411 of the rotating part 410 can be driven to press the flexible circuit board 2 to rotate around the rotation axis of the rotary shaft 430. Furthermore, by providing a limiting protrusion 412, it can engage with electrical components on the flexible circuit board 2. These electrical components can be sensors on the flexible circuit board 2, thereby limiting the relative position between the flexible circuit board 2 and the rotating part 410, and also limiting the relative position between the flexible circuit board 2 and the support surface 210, thus improving the bending accuracy of the flexible circuit board 2.

[0071] like Figure 5 As shown, in some embodiments, the support component 200 is provided with a positioning protrusion 214, and the positioning protrusion 214 and the support surface 210 define a positioning groove 215 for accommodating the flexible circuit board 2. By providing the positioning groove 215, the relative position of the flexible circuit board 2 and the support component 200 in the second direction can be defined, preventing the flexible circuit board 2 from separating from the support surface 210.

[0072] For example, the positioning groove 215 can be open on both sides in the first direction. The support assembly 200 also includes a plug 220. The plug 220 and the rotating part 410 are located on both sides of the positioning groove 215. The plug 220 is detachably connected to the support assembly 200 and seals one end opening of the positioning groove 215. In this way, the positioning groove 215 has a simple structure, and the plug 220 can be used to define the relative position between the flexible circuit board 2 and the support surface 210.

[0073] Furthermore, such as Figure 6 As shown, the pressing member 310 is provided with a positioning notch 311. When the pressing member 310 abuts against the support surface 210, the positioning protrusion 214 is inserted into the positioning notch 311. In this way, precise positioning between the pressing member 310 and the support assembly 200 can be achieved. Since both the pressing member 310 and the second driver 340 are mounted on the second mounting plate 380, the precise positioning between the pressing member 310 and the support assembly 200 can also be improved, thereby improving the precise positioning between the bending member 320 and the support assembly 200, which is beneficial to improving the consistency of the bending member 320 in bending the flexible circuit board 2.

[0074] like Figure 5 As shown, in some embodiments, the support component 200 is provided with a clearance notch 216, which is located on the side of the support component 200 facing the pressing component 300. By providing the clearance notch 216, a human hand or a robotic arm can be prevented from placing the flexible circuit board 2 on the support component 200 or removing the flexible circuit board 2 from the support component 200.

[0075] Furthermore, the support surface 210 includes a first support surface 211 and a second support surface 212, which are located on opposite sides of the clearance notch 216. This provides more reliable support for the flexible circuit board 2, preventing it from tilting at the clearance notch 216 due to lack of support. Additionally, the bending point 213 is located on the first support surface 211, allowing the pressing member 310 to abut against it. This ensures a closer distance between the bending point of the flexible circuit board 2 and the pressing member 310, guaranteeing effective positioning and improving bending consistency.

[0076] like Figure 3 As shown, in some embodiments, the flexible circuit board bending device 1 further includes a channel component 500, which is disposed on the base 100 and has a negative pressure channel. The support surface 210 has a suction port. One end of the negative pressure channel is connected to the suction port, and the other end of the negative pressure channel is used to connect to a vacuum generator.

[0077] For example, the vacuum generator can be integrated into the base 100, or the vacuum generator can be located outside the flexible circuit board bending device 1 and then connected to the channel component 500 when needed.

[0078] When the vacuum generator is connected to the channel component 500, and the vacuum generator is in a vacuum state, the suction port can generate a suction force on the flexible circuit board 2, thereby preventing relative displacement between the support component 200 and the flexible circuit board 2 and improving the positioning reliability between the support component 200 and the flexible circuit board 2.

[0079] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
