Description

Technical Field

[0001] This utility model relates to the field of automated production technology of flexible circuit boards, and in particular to a high-precision bending device for flexible circuit boards applied in the SMT industry. Background Technology

[0002] Flexible printed circuit boards (FPCs) are circuit boards made from flexible substrates. Due to their unique bendability and foldability, they offer advantages such as lightness, thinness, and flexibility compared to ordinary rigid boards, making them widely used in modern electronic products. As electronic products become increasingly thinner, smaller, and more multifunctional, the performance requirements for flexible circuit boards are also becoming more stringent.

[0003] In particular, high-precision bending of EMI (Electromagnetic Interference) components in flexible circuit boards is especially important. EMI materials are typically composed of copper foil, a substrate, and a protective layer, possessing good flexibility and conductivity. However, existing bending devices have at least the following problems:

[0004] 1. Due to the thin and flexible nature of flexible circuit boards and EMI components, and the relatively long length of some flexible circuit board products, existing bending equipment has problems with positioning difficulties and inaccurate positioning when positioning circuit board products. This leads to offset during subsequent bending, and the bending angle and bending position cannot meet the design requirements, resulting in a low yield.

[0005] 2. Existing bending equipment is prone to uneven bending during bending, which leads to product defects and fails to provide an accurate benchmark for subsequent assembly, thus reducing production efficiency.

[0006] In view of this, how to solve the problems of inaccurate positioning and uneven bending of existing FPC flexible circuit board bending equipment has become the research topic to be solved by this utility model. Utility Model Content

[0007] This invention provides a high-precision bending device for flexible circuit boards, which aims to solve the problems of inaccurate positioning and uneven bending existing in the bending devices for FPC flexible circuit boards.

[0008] To achieve the above objectives, this utility model proposes a high-precision bending device for flexible circuit boards, used to bend components in flexible circuit boards. Its innovation lies in:

[0009] The bending device includes a fixed platform, a positioning component, a moving platform, a motion module, an upper fixed module, an upper bending module, and a lower bending module.

[0010] At least one product positioning station is provided on the fixed platform, and a bending station is provided on one side of the product positioning station.

[0011] The positioning component includes multiple positioning blocks arranged on both sides along the length direction of the product positioning station and along the length direction of the bending station.

[0012] The mobile platform is mounted across the fixed platform, and the telescopic end of the motion module is connected to the mobile platform and the motion module drives the mobile platform to approach or move away from the bending station.

[0013] The upper fixed module and the upper bending module are set on the mobile platform corresponding to the bending station. The upper fixed module includes an upper fixed mover and a first upper drive unit for driving the upper fixed mover to move. The upper bending module includes an upper bending mover and a second upper drive unit for driving the upper bending mover to move.

[0014] The lower bending module is located below the fixed platform corresponding to the bending station. The lower bending module includes a lower bending heating actuator and a lower driving unit for driving the lower bending heating actuator.

[0015] The relevant contents of this utility model are explained as follows:

[0016] 1. In the above-mentioned technical solution of this utility model, in order to address the problems of inaccurate positioning and uneven bending of existing FPC flexible circuit board bending equipment, a high-precision bending equipment for flexible circuit boards of this utility model is innovatively designed. The product positioning station and bending station on the fixed table of this high-precision bending equipment for flexible circuit boards, considering the thin and flexible characteristics of flexible circuit boards and EMI components, have multiple positioning blocks arranged along the length direction of the product positioning station and on both sides along the length direction of the bending station. Thus, multiple or multiple sets of positioning blocks accurately position the flexible circuit board and the component (EMI component) to be bent on the flexible circuit board. Before bending, the upper fixed module presses down the component to be bent to ensure that there is no positional deviation during bending. This design ensures the stability and reliability of the EMI during bending. Furthermore, considering the material properties of the EMI components and the requirements for consistency and accuracy during bending, an upper fixing module for fixing and assisting bending, an upper bending module for bending, and a lower bending module for bending and heating were designed. During the bending process, the lower bending heating actuator of the lower bending module is in contact with the bending area of ​​the component to be bent, allowing the EMI component to be heated and shaped. The use of the upper bending module avoids product defects caused by uneven bending of the EMI, thus providing an accurate benchmark for subsequent assembly. By controlling the temperature of the lower bending heating actuator, the material properties of the EMI can be optimized, ensuring that the EMI maintains good electrical characteristics and mechanical stability.

[0017] 2. In the above technical solution, the lower bending heating actuator has a heating part and a bending head. The bending head is thermally connected to the heating part. The bending head is arranged facing upward. The thermal connection here can be that the bending head and the heating part (heating block, heating coil, etc.) are designed as one piece, or the bending head and the heating part can be set separately, and then heat is conducted between the bending head and the heating part through a component with good thermal conductivity (conventional thermally conductive metal, thermally conductive ceramic, etc.).

[0018] 3. In the above technical solution, the mobile platform is provided with an upper fixing plate and a fixing column. The first upper driving unit and the second upper driving unit are fixed on the upper fixing plate. The upper fixing plate is fixed on the mobile platform through the fixing column. This structure allows for better installation of the upper fixing module and the upper bending module on the mobile platform. Furthermore, multiple sets of upper fixing plates and fixing columns can be set for multiple sets of upper fixing modules and upper bending modules, thereby facilitating the integrity of the mechanism corresponding to the bending operation of a flexible circuit board and making maintenance and replacement easier.

[0019] 4. In the above technical solution, the motion module includes a track, a slider, and a motion drive unit. The track is set on both sides of the fixed platform and is parallel to the length direction of the product positioning station. The slider is connected to the moving platform and slides with the track. The moving platform is connected to the drive end of the motion drive unit. The upper fixed module and the upper bending module are fixedly installed on the moving platform, so that the process of the moving platform approaching or moving away from the bending station is more reasonable, reliable, and accurate, ensuring that the upper fixed module and the upper bending module can be sent above the corresponding lower bending module.

[0020] 5. In the above technical solution, two product positioning stations are arranged parallel to each other along the length direction on the fixed platform, and two bending stations are set on the two product positioning stations. Two sets of upper fixed modules and upper bending modules are set on the mobile platform, and lower bending modules are set below each of the bending stations, so as to realize that bending operations can be performed simultaneously at the two stations, which greatly improves work efficiency.

[0021] 6. In the above technical solution, the component to be bent further includes parts protruding from both sides in the length direction. Correspondingly, positioning blocks are provided on the protruding parts on both sides of the bending station, and positioning blocks are also provided at the top of the length of the bending station. This structural design makes the positioning of the flexible circuit board and the component to be bent on it more reliable and stable.

[0022] 7. In the above technical solution, the positioning block has an inwardly inclined guide surface on one side facing the product positioning station or bending station. The lower section of the guide surface is a vertical abutting surface for pressing against the flexible circuit board / the part to be bent. This design allows the flexible circuit board and the part to be bent on it to be guided by the guide surface when placing them into the product positioning station or bending station, making the placement process faster and protecting the flexible circuit board and the part to be bent on it from damage. At the same time, the abutting surface reliably and stably positions the flexible circuit board and the part to be bent on it.

[0023] 8. In the above technical solution, safety light curtains are provided on both sides of the fixed platform, and blocking blocks for restricting the movement of the mobile platform are provided on both sides of the track on the fixed platform, so as to ensure the safety of the workers during the bending operation, as well as the protection and precise positioning of the mobile platform.

[0024] 9. In the above technical solution, the bending equipment also includes a control cabinet located on one side of the fixed platform. The motion drive unit of the motion module is located inside the control cabinet. The control cabinet is also equipped with an air source module and an air pressure gauge is installed on one side of the control cabinet. This enables the high-precision bending equipment for flexible circuit boards to complete bending operations independently. Apart from an external power supply, no other deployment is required, and it can be quickly applied to production.

Many specific details are set forth in the following description to provide a thorough understanding of this application. 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.

This ensures the stability and reliability of EMI during bending and avoids product defects caused by uneven bending of EMI components.

[0076] like Figures 1 to 11 As shown in the figure, this utility model embodiment proposes a high-precision bending device for flexible circuit boards, which is used to bend the component 92 to be bent in the flexible circuit board 91.

To address the material properties of component I and the requirements for consistency and accuracy during bending, an upper fixing module 5 for fixing and assisting bending, an upper bending module 6 for bending, and a lower bending module 7 for bending and heating were designed. During the bending process, the lower bending heating actuator 71 of the lower bending module 7 is in contact with the bending part of the component 92 to be bent, allowing the EMI component to be heated and shaped. The use of the upper bending module 6 avoids product defects caused by uneven bending of the EMI component, thus providing an accurate benchmark for subsequent assembly.

The thermal connection here can be that the bending head 712 and the heating part 711 (heating block, heating coil, etc.) are designed as one piece, or the bending head 712 and the heating part 711 are set separately, and then heat is conducted between the bending head 712 and the heating part 711 through a component with good thermal conductivity (conventional thermally conductive metal, thermally conductive ceramic, etc.).

The upper fixed module 5 and the upper bending module 6 are fixedly installed on the moving platform 3, so that the process of the moving platform 3 approaching or moving away from the bending station 12 is more reasonable, reliable, and accurate, ensuring that the upper fixed module 5 and the upper bending module 6 can be sent above the corresponding lower bending module 7.

[0086] In another embodiment of this utility model, two product positioning stations 11 are arranged parallel to each other along the length direction on the fixed platform 1, and two bending stations 12 are arranged on the two product positioning stations 11. Two sets of upper fixed modules 5 and upper bending modules 6 are arranged on the mobile platform 3, and lower bending modules 7 are arranged below each of the bending stations 12, so as to realize the bending operation of the two stations at the same time, which greatly improves the work efficiency.

Refer to [reference needed]. Figure 1 , Figure 5 As shown.

[0099] 2. The motion drive unit 43 of the motion module 4 drives the moving platform 3 to slide along the track 41, causing the upper fixed module 5 and the upper bending module 6 to move above the bending station 12 and correspondingly directly above the lower bending module 7. (See reference...) Figure 8 As shown.

[0100] 3.

(Refer to...) Figure 9 As shown.

[0101] 4. The lower drive unit 72 of the lower bending module 7 drives the lower bending heating mover 71 to move upward. The upward movement of the lower bending heating mover 71 causes the movable end of the EMI to bend according to the shape of the lower bending mover, and the EMI is continuously heated and shaped during this process. (See reference...) Figure 10 As shown.

[0102] 5. Immediately afterwards, the upper bending actuator 61 is pressed down, pressing down the end of the EMI that was lifted by the lower bending actuator, and holding it for 3 seconds. It is then shaped using high temperature. (Refer to...) Figure 11 As shown.

[0103] 6. All moving parts are reset, the moving platform 3 is reset, and the flexible circuit board 91 is removed, thus completing the bending operation.

[0104] It should also be noted that in the embodiments of this utility model, the control of each module and mechanism is all prior art, and those skilled in the art can understand its principles and structure.

[0105] In the first upper drive unit, second upper drive unit, lower drive unit, motion drive unit, etc. of this utility model, a linear drive mechanism (10) is adopted. The linear drive mechanism can be one of the following mechanisms:

[0106] (a) Cylinder, the piston rod of the cylinder serves as the working end of the linear drive mechanism;
