Description

Technical Field

[0001] The utility model relates to the technical field of circuit board testing, in particular to a desktop FPC folding machine. Background Art

[0002] An FPC is a printed circuit board made of polyimide or polyester film as the substrate, which has high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness, and good bending performance. During the production process of FPC, the bending performance of the circuit board is usually tested by a folding endurance tester.

[0003] The application fields of FPCs for different products of different customers are not the same, so the bending conditions of FPCs are also different. Some users need the FPC to be bent once, and some products need the FPC to be bent multiple times. For example, the FPC used for a folding screen needs to be folded tens of thousands or even hundreds of thousands of times. Therefore, how to test the number of bending times of the FPC and the circuit performance of the FPC after bending is a very important issue in this field.

[0004] For the bending test of FPCs, the traditional method is to use a round rod to perform a 0°-180°-0° bend (one bend is from the horizontal plane to the other horizontal plane at 180° and then back to the 0° horizontal plane), until the specified number of bending times is reached. In this bending test method, the stressed position will shift during the bending process, resulting in the test conclusion being unable to truly reflect the bending resistance performance of the flexible part of the FPC, thus affecting the final experimental determination. During the test process, the line resistance cannot be monitored in a timely manner, and for special tests, the problems cannot be truly reflected. In addition, after a circuit break occurs, the specific number of folding endurance cannot be known in a timely manner, affecting the experimental determination.

[0005] In view of this, the utility model deeply conceives in response to the many deficiencies and inconveniences caused by the imperfect design of the existing FPC bending test structure, and actively researches, improves, and develops the present utility model through trial production. Summary of the Utility Model

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a desktop FPC folding machine that can meet the requirements of various bending degrees and bending times of various FPCs and truly reflect the bending performance of the FPC.

[0007] To achieve the above objective, the solution of the utility model is as follows:

[0008] A desktop FPC folding machine, which includes a chassis, a driving motor, a rotating shaft, a folding plate, an upper fixture and a lower fixture. The chassis has brackets arranged at intervals. The driving motor is fixedly arranged on one of the brackets. One end of the rotating shaft is connected to the output shaft of the driving motor, and the other end of the rotating shaft is connected to one end of the folding plate. The other end of the folding plate is rotatably arranged on the other bracket. The upper fixture is detachably arranged on the folding plate. The lower fixture is arranged on the chassis and corresponds to the upper fixture. A bending area is formed between the adjacent ends of the upper fixture and the lower fixture. One end of the FPC is fixedly arranged on the upper fixture, and the other end of the FPC is fixedly arranged on the lower fixture.

[0009] Furthermore, a bottom plate bracket is arranged on the chassis. The lower fixture is detachably fixed on the bottom plate bracket. One end of the upper fixture close to the lower fixture is connected to the rotating shaft. The upper fixture is elevated by a bracket so that the rotating end of the upper fixture corresponds to the lower fixture.

[0010] Furthermore, at least one set of corresponding screw holes are respectively arranged on the upper fixture and the folding plate, and the upper fixture and the folding plate are locked together by screws.

[0011] Furthermore, the upper fixture is provided with adjusting long holes, and the position of the upper fixture is adjusted by corresponding to the screw holes of the folding plate at different positions of the adjusting long holes.

[0012] Furthermore, a plurality of FPCs are arranged side by side on the upper fixture and the lower fixture, and there are intervals between adjacent FPCs.

[0013] Furthermore, the brackets are arranged on the chassis on one side of the lower fixture. The bracket corresponding to the side of the driving motor is provided with a motor mounting seat. The driving motor is mounted on the motor mounting seat. One end of each of the two adapter plates is provided with corresponding limit slots. The two ends of the folding plate are respectively detachably fixed in the limit slots. One of the adapter plates is fixed together with the rotating shaft, and the other adapter plate is rotatably arranged at the top of the bracket.

[0014] Furthermore, an indicating module corresponding to the FPC is also arranged on the upper fixture or the lower fixture. The indicating module is connected to the FPC. A power supply module for powering the FPC is arranged on the upper fixture or the lower fixture, and a power supply connector corresponding to the FPC is arranged on the power supply module.

[0015] Furthermore, each FPC has multiple lines. The indicating module includes at least one indicator light and an indicating circuit board. The indicator light is mounted on the indicating circuit board. The indicating circuit board is provided with indicator lights corresponding to the number of FPC lines corresponding to the FPC. The FPC is connected to the indicating circuit board through a cable connector so that each line of the FPC corresponds to an indicator light.

[0016] Furthermore, a display screen for connecting the FPC and the driving motor is arranged on the chassis.

[0017] When the desktop FPC folding machine of the present utility model is in use, one end of the FPC is fixed on the upper fixture, and the other end of the FPC is fixed on the lower fixture. The bending part of the FPC is located in the bending area between the upper fixture and the lower fixture. The folding plate and the upper fixture are elevated by a bracket to facilitate the flipping of the folding plate and the upper fixture. One end of the folding plate is connected to a rotating shaft, and the rotating shaft is connected to a driving motor. The driving motor can drive the rotating shaft to rotate, thereby driving the folding plate and the upper fixture to move together. By controlling the steering and speed of the driving motor, the folding angle and the number of folding times of the folding plate can be controlled. Since the FPC is fixed by the lower fixture, when the upper fixture drives one end of the FPC to rotate, the other end of the FPC is always fixed at the bending part and will not be displaced, so that the bending resistance performance of the FPC can be truly reflected. The upper fixture and the lower fixture adopt a detachable structure, which is convenient for replacing different fixtures for different FPCs. Description of the Drawings

In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more than two.

[0026] As Figures 1 to 4 shown, the present utility model discloses a desktop FPC folding machine 10, which includes a chassis 1, a driving motor 2, a rotating shaft 3, a folding plate 4, an upper fixture 5 and a lower fixture 6. The chassis 1 is provided with spaced brackets 11. The driving motor 2 is fixedly arranged on one of the brackets 11. One end of the rotating shaft 3 is connected to the output shaft of the driving motor 2, and the other end of the rotating shaft 3 is connected to one end of the folding plate 4. The other end of the folding plate 4 is rotatably arranged on the other bracket 11. The upper fixture 5 is detachably arranged on the folding plate 4. The lower fixture 6 is arranged on the chassis 1 and corresponds to the upper fixture 5. A bending area is formed between the adjacent ends of the upper fixture 5 and the lower fixture 6. One end of the FPC is fixedly arranged on the upper fixture 5, and the other end of the FPC is fixedly arranged on the lower fixture 6.

[0027] When the desktop FPC folding machine 10 of the present utility model is in use, one end of the FPC is fixed on the upper fixture 5, and the other end of the FPC is fixed on the lower fixture 6. The bending part of the FPC is located in the bending area between the upper fixture 5 and the lower fixture 6. The folding plate 4 and the upper fixture 5 are elevated by the brackets 11, which is convenient for the folding plate 4 and the upper fixture 5 to flip. One end of the folding plate 4 is connected to the rotating shaft 3, and the rotating shaft 3 is connected to the driving motor 2. The driving motor 2 can drive the rotating shaft 3 to rotate, and then drive the folding plate 4 and the upper fixture 5 to move together. By controlling the rotation direction and speed of the driving motor 2, the folding angle and the number of folding times of the folding plate 4 can be controlled. Since the FPC is fixed by the lower fixture 6, when the upper fixture 5 drives one end of the FPC to rotate, the other end of the FPC is always fixed and the bending part will not be displaced, so that the bending resistance performance of the FPC can be truly reflected. The upper fixture 5 and the lower fixture 6 adopt a detachable structure, which is convenient for replacing different fixtures for different FPCs.

[0028] In this embodiment, a bottom plate bracket 12 is provided on the chassis 1, and the lower fixture 6 is detachably fixed on the bottom plate bracket 12, thereby raising the lower fixture 6. One end of the upper fixture 5 close to the lower fixture 6 is connected to the rotating shaft. The upper fixture 5 is raised by the bracket 11, so that the rotating end of the upper fixture 5 corresponds to the lower fixture 6. Raising the lower fixture 6 and the upper fixture 5 can expand the rotation range of the upper fixture 5, and thus be applicable to more FPCs with different bending angles.

[0029] There are various ways to fix the upper fixture 5 and the folding plate 4. For example, screw attachment, snap fit, or other connection methods can be used. In this embodiment, the screw locking method is adopted. A plurality of corresponding screw holes are respectively provided on the upper fixture 5 and the folding plate 4, and the upper fixture 5 and the folding plate 4 are locked together by screws. In order to facilitate the adjustment of the installation position of the upper fixture 5, in this embodiment, an adjustment slot 51 is provided on the upper fixture 5, and the position of the upper fixture 5 can be adjusted by corresponding the screw holes of the folding plate 4 at different positions of the adjustment slot 51.

[0030] A plurality of FPCs can be arranged side by side on the upper fixture 5 and the lower fixture 6, and adjacent FPCs are arranged at intervals. Designed in this way, multiple FPCs can be tested simultaneously at one time, improving the test efficiency.

[0031] In this embodiment, the bracket 11 is provided at both ends of the chassis on one side of the lower fixture 6. A motor mounting seat 21 is provided on the bracket 11 corresponding to one side of the driving motor 2, and the driving motor 2 is mounted on the motor mounting seat 21. One adapter plate 8 is respectively provided at both ends of the folding plate 4. Limiting slots 81 corresponding to each other are provided at one ends of the two adapter plates 8. Both ends of the folding plate 4 are detachably fixed in the limiting slots 81, which is convenient for replacing the folding plate 4. One adapter plate 8 is fixed to the rotating shaft, and the other adapter plate 8 is rotatably arranged at the top end of the bracket 11. The folding plate 4 is designed to be a detachable structure. When the folding plate 4 cannot meet the usage requirements of special FPCs, the folding plate 4 can be disassembled and a folding plate 4 that meets the requirements can be installed, further improving the applicable range of the present utility model.

[0032] In order to observe the bending condition of the FPC at any time and visually display the bending resistance effect of the FPC, an indicating module corresponding to the FPC is further provided on the upper fixture 5 or the lower fixture 6, and the indicating module is connected to the FPC. Each FPC has multiple circuits. The indicating lights are installed on an indicating circuit board. The indicating circuit board is provided with indicating lights corresponding to the number of FPC circuits. The FPC is connected to the indicating circuit board through a flexible cable connector, so that each circuit of the FPC corresponds to an indicating light. When the FPC is subjected to a bending test, the bending state of the FPC can be visually displayed through the lighting and extinguishing of the indicating lights. The indicating module can also adopt a general indication method, that is, each FPC is connected to an indicating light. Once a problem occurs in the circuit during the bending process of the FPC, the indicating light can judge whether the circuit of the FPC is normal by lighting a red light or extinguishing. A power supply module for powering the FPC is provided on the upper fixture 5 or the lower fixture 6. The power supply module is provided with a power connector corresponding to the FPC. The power supply module can adopt a mobile power supply or directly use a data cable for charging.

[0033] In order to facilitate the control of the setting of the folding parameters, including the folding angle, the number of folding times, etc., the present utility model is further provided with a display screen 7, and the folding times and state of the FPC can be visually displayed through the display screen 7.

[0034] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the technical field to which it belongs shall be regarded as not departing from the patent scope of the present utility model.
