Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, and specifically to a rapid demolding device for a precision mold of a flexible circuit board. Background Technology

[0002] Flexible circuit boards, also known as "FPC flexible boards", "flexible circuit boards" or "flexible circuit boards", are printed circuits made of flexible insulating substrates. The biggest difference between them and common "rigid boards" is their ability to bend, fold, and roll, which can adapt to dynamic bending or static installation requirements in three-dimensional space. In the production process of flexible circuit boards, the circuit boards need to be punched by stamping dies, and then removed by demolding devices.

[0003] Currently, the lack of a dual demolding mechanism in demolding devices means that flexible circuit boards are prone to warping and displacement during traditional ejector pin demolding, leading to scratches on the gold fingers or displacement of the reinforcing plate, which affects product quality and production efficiency. Therefore, a rapid demolding device for precision molds of flexible circuit boards is proposed to add a dual demolding mechanism. By using a lower support and upper suction method, the accuracy and stability of flexible circuit board demolding are improved, the deformation of thin materials during demolding is reduced, and the performance is enhanced. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a rapid demolding device for precision molds of flexible circuit boards, which improves the accuracy and stability of demolding of flexible circuit boards by using a bottom support and top adsorption method, thereby improving the performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a quick demolding device for precision molds of flexible circuit boards, including a base, a flipping component and a spraying component. The base is provided with a lower mold on the top, a flipping component is provided on one side of the lower mold, and a spraying component is provided at the bottom of the flipping component. The lower mold is slidably connected to a release plate. The flipping assembly includes a fixed frame, and the base is connected to the fixed frame by bolts. A rotating frame is mounted on the top of the fixed frame by a bearing. A hollow plate is connected to the bottom of the rotating frame by bolts. Suction cups are equidistantly arranged on the bottom of the hollow plate.

[0006] By adopting the above technical solution, a dual demolding mechanism is added, which uses the bottom ejection and top suction methods to achieve dual demolding action.

[0007] Specifically, the spray assembly includes a spray pipe with air outlets evenly spaced on its surface. A mounting base is fitted onto the end of the spray pipe, and the mounting base is connected to a rotating frame by bolts.

[0008] Specifically, a vacuum pump is bolted to one side of the fixed frame, and the air inlet of the vacuum pump is connected to the hollow plate through a hose. An exhaust pipe is provided at the air outlet of the vacuum pump.

[0009] Specifically, a lead screw is mounted on the bottom of the lower mold via a bearing, and a sliding block is provided at the end of the lead screw. The sliding block is connected to the demolding template via bolts. A servo motor is connected to the lower mold via bolts, and the servo motor is connected to the lead screw via a drive shaft.

[0010] Specifically, the top of the base is provided with a guide post located on the periphery of the lower mold, the guide post is fitted with an upper mold base, and the bottom of the upper mold base is provided with an upper mold corresponding to the lower mold.

[0016] To facilitate the use of a bottom support and top suction method, thereby improving the accuracy and stability of flexible circuit board demolding and enhancing its performance, such as... Figure 1-3 As shown, the present invention provides a quick demolding device for a precision mold of a flexible circuit board, comprising a base 1, a flipping component 3, and a spraying component 4. A lower mold 2 is provided on the top of the base 1, a flipping component 3 is provided on one side of the lower mold 2, and a spraying component 4 is provided at the bottom of the flipping component 3. The lower mold 2 is slidably connected to a stripping template 201. The flipping assembly 3 includes a fixed frame 301, and the base 1 is connected to the fixed frame 301 by bolts. The top of the fixed frame 301 is mounted with a rotating frame 302 by bearings. The bottom of the rotating frame 302 is connected with a hollow plate 303 by bolts. Suction cups 304 are equidistantly arranged at the bottom of the hollow plate 303.

[0017] In use, a double demolding mechanism is added by using the demolding template 201, the fixed frame 301, the rotating frame 302, the hollow plate 303 and the suction cup 304. By using the bottom push and the top suction, a double demolding action is achieved, which improves the accuracy and stability of demolding.

[0018] The suction cup is made of 304 silicone.

[0019] To improve the effectiveness of mold use, for example, such as Figure 2 , Figure 4 As shown, the present invention also includes the following: the spray assembly 4 includes a spray pipe 401, the surface of the spray pipe 401 is provided with air outlets 402 at equal intervals, the end of the spray pipe 401 is fitted with a mounting base 403, and the mounting base 403 is connected to the rotating frame 302 by bolts.

[0020] During use, an auxiliary cleaning mechanism is added through the nozzle 401, air outlet 402 and mounting base 403, and the airflow blown by the vacuum mechanism is used to clean the inner wall of the mold after use.

[0021] For example, such as Figure 2 As shown, the present invention also includes a vacuum pump 305 connected to one side of the fixed frame 301 by bolts, and the air inlet of the vacuum pump 305 is connected to the hollow plate 303 through a hose. An exhaust pipe 306 is provided at the air outlet of the vacuum pump 305. A rotary motor 307 is connected to the surface of the fixed frame 301 by bolts, and the rotary motor 307 is connected to the rotating frame 302 through a drive shaft.

[0022] In use, the vacuum pump 305 and the exhaust pipe 306 facilitate the generation of a vacuum for adsorption and demolding. The rotary motor 307 facilitates the reciprocating rotation of the rotating frame 302 for demolding and unloading. The exhaust pipe 306 includes a diversion pipe, one end of which is connected to the nozzle 401. Both the exhaust pipe 306 and the diversion pipe are equipped with control valves.

[0023] For example, such as Figure 3 As shown, the present invention also includes a lead screw 202 mounted on the bottom of the lower mold 2 via a bearing, a sliding block 203 provided at the end of the lead screw 202, and the sliding block 203 connected to the demolding template 201 via bolts. A servo motor 204 is bolted to the lower mold 2, and the servo motor 204 is connected to the lead screw 202 via a drive shaft.

[0024] In use, the lead screw 202, the sliding block 203 and the servo motor 204 facilitate the vertical movement of the demolding template 201 to perform the downward demolding action. The sliding block 203 is threadedly connected to the lead screw 202 through a reserved threaded hole.

[0027] In use, the present invention first uses a hydraulic cylinder to drive the upper mold base 6 and the upper mold 7 to slide down for mold closing and stamping. After the stamping is completed, the servo motor 204 drives the lead screw 202 to rotate, and the sliding block 203 slides to drive the demolding plate 201 to rise, realizing the upward demolding action. At the same time, the rotary motor 307 drives the rotating frame 302 to rotate to the top of the lower mold 2. Simultaneously, the vacuum pump 305 is manually turned on, and the flexible circuit board is adsorbed through the hollow plate 303 and the suction cup 304 to perform the upward suction demolding action. Then, the rotary motor 307 drives the rotating frame 302 to rotate again to reset and complete the demolding and material discharge action. After the demolding action is completed, the control valve of the manifold can be manually opened. The airflow generated by the vacuum pump 305 is blown through the exhaust pipe 306, manifold, nozzle 401 and air outlet 402 to blow away the residual waste on the inner wall of the lower mold 2, so as to improve the performance of the device. The overall structure is simple and easy to operate, and the use is more stable and reliable.
