Description

Technical Field

[0001] This utility model belongs to the field of flexible board bending technology, and in particular relates to a flexible board bending device. Background Technology

[0002] Standardized internal structural design of electronic products typically adopts modular design. Electronic product modules are connected and communicate with the motherboard of the electronic product through FPC flexible printed circuit boards. Due to the compact structural design of electronic product components, the space between modules is limited. In order to enable the flexible printed circuit boards to better connect with the motherboard, the FPC flexible printed circuit boards need to be arranged according to the design path, and the flexible printed circuit boards need to be bent before assembly.

[0003] In the prior art, Chinese invention patent CN115188541B discloses a flexible cable bending device, which includes a worktable, loading and unloading bins, a bending turntable, and a handling robot. The worktable includes a bending area and a loading and unloading area. The outer ring area of ​​the bending turntable is divided into M peripheral areas with the same angle range. Each peripheral area is equipped with a set of fixtures, and the number of fixtures in each set is L, where L is a natural number. Each bending station is equipped with a base plate, and the base plate is equipped with a support plate cylinder and a bending upper convex support seat. Although this solution can realize the bending action of flexible boards, there is no positioning between the structure on the bending station and the bending turntable. Moreover, the size of the flexible boards is generally very small, and the bending turntable tends to rotate circumferentially, which will reduce the bending accuracy. Furthermore, the cable support seat and the pressure block are not precisely positioned when supporting and pressing the product, which will further reduce the bending accuracy.

[0004] Therefore, it is necessary to provide a flexible sheet bending device to solve the above-mentioned technical problems. Utility Model Content

Improve processing quality and process control capabilities: (1) Local heating function: The clamping and supporting parts are integrated with adjustable heating rods. This design allows for precise local heating of the product bending area, which can improve the ductility of the material, reduce internal stress and springback during bending, effectively reduce bending resistance, thereby improving the accuracy and consistency of bending angle, especially for thermoplastic or temperature-sensitive materials; (2) Optimized mechanical transmission: The bending unit adopts a gear-rack mechanism to convert the linear motion of the fourth driving part into the rotational motion of the bending part.

[0025] The first support plate 212 is provided with a second positioning pin 218, and the third support plate 222 is provided with a second positioning hole 225 that cooperates with the second positioning pin 218. The cooperation between the second positioning pin 218 and the second positioning hole 225 can achieve the accuracy of the vertical positioning of the first support plate 212 and the third support plate 222, thereby ensuring the accuracy of the bending action.

[0026] The first support plate 212 and the third support plate 222 are both mounted on the mounting base 25 by sliding the first slider 24 up and down. The mounting base 25 is provided with a first slide rail 251 that cooperates with the first slider 24.

Supported on the bottom surface of the product, the first driving component 211 drives the first support plate 212 to move the pressing component 215 downward to press it against the upper surface of the product. At this time, the first positioning pin is first inserted into the first positioning hole 217 on the positioning plate 11, and then further inserted downward into the first positioning hole 217 on the third support plate 222. At the same time, the second positioning pin 218 is inserted into the second positioning hole 225. Moreover, at this time, the bending component 231 is located on the lower surface of the product. When the fourth driving component 234 drives the rack 233 to move up and down, it drives the gear 232 to rotate. The gear 232 drives the bending component 231 to rotate, thereby realizing the bending action of the product. Several bending units 23 perform bending actions at the same time, which can realize the bending action of multiple products.
