Description

Technical Field

[0001] This invention relates to the field of testing fixture technology, and in particular to an integrated FPC bending and testing carrier and testing equipment. Background Technology

[0002] Generally, FPC circuit components arrive in a flat state. After being installed in a housing, they need to be bent to conform to the shape of the housing. For example, ... Figure 1 As shown, the FPC circuit assembly 1 includes a relay board 101, a first flexible circuit board 102 electrically connected to the relay board 101, a second flexible circuit board 103 electrically connected to the relay board 101 and disposed opposite to the first flexible circuit board 102, and a third flexible circuit board 104 electrically connected to the relay board 101.

[0003] After the FPC circuit assembly 1 is installed into the housing, a first bending point 1021 is generated at the first flexible circuit board 102, a second bending point 1031 is generated at the second flexible circuit board 103, and a third bending point 1041 is generated at the third flexible circuit board 104.

[0004] Bending may damage the FPC circuit components. Therefore, after installing the FPC circuit components into the housing, the electrical functions of the FPC circuit components need to be re-inspected.

[0005] However, after installing the FPC circuit assembly into the housing and then retesting its electrical function, if the FPC circuit assembly is found to be damaged due to bending, it needs to be removed from the housing before the housing can be recycled. This not only makes the "installing the FPC circuit assembly into the housing" process redundant, but also adds the "removing the FPC circuit assembly from the housing" process, greatly increasing production costs.

[0006] Therefore, there is a need to develop a device that can perform electrical function testing on FPC circuit components under bending conditions before they are installed into the housing, in order to reduce production costs.

[0007] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0080] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0081] In the description of this invention, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component present simultaneously. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be an intermediate component present simultaneously.

[0082] Furthermore, terms such as “long,” “short,” “inner,” and “outer” indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the purpose of describing the present invention and are not intended to indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of the present invention.

[0083] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0084] This invention provides an integrated carrier and testing equipment for bending and testing FPC circuit components, which is suitable for application scenarios of bending testing FPC circuit components. It can perform electrical function testing on FPC circuit components under bending conditions before the FPC circuit components are installed in the housing, which helps to reduce production costs.

[0085] First, this embodiment provides an integrated FPC bending and testing carrier for bending FPC circuit components.

[0086] Specifically, see Figure 1The FPC circuit assembly 1 includes a relay board 101, a first flexible circuit board 102 electrically connected to the relay board 101, a second flexible circuit board 103 electrically connected to the relay board 101 and disposed opposite to the first flexible circuit board 102, and a third flexible circuit board 104 electrically connected to the relay board 101.

[0087] See Figure 2 The FPC folding and testing integrated vehicle 200 includes a base plate 2, a rotating cover plate 3, a rotating side plate 4, an oblique push assembly 5, and a horizontal push assembly 6.

[0088] See Figure 3 The base plate 2 is used to place the third flexible circuit board 104, and the rotating cover plate 3 is hinged to one side of the base plate 2 to cooperate with the base plate 2 to press the third flexible circuit board 104. Further, the base plate 2 has an adapter 201 for electrical connection with the third flexible circuit board 104 at a position corresponding to the third flexible circuit board 104. After the rotating cover plate 3 presses the third flexible circuit board 104 onto the base plate 2, the top of the adapter 201 can be electrically connected to the third flexible circuit board 104.

[0089] The rotating side plate 4 is hinged to the other side of the base plate 2 and is used to place the transfer plate 101, the first flexible circuit board 102 and the second flexible circuit board 103. The rotating side plate 4 is provided with a first bending clearance groove 401 corresponding to the position of the first flexible circuit board 102 and a second bending clearance groove 402 corresponding to the position of the second flexible circuit board 103. The rotating side plate 4 has a feeding state that rotates to be flush with the base plate 2 and a bending state that rotates to be perpendicular to the base plate 2 to bend on the third flexible circuit board 104 to form a third bending point 1041.

[0090] In this embodiment, a side plate torsion spring 701 is provided at the hinge position between the rotating side plate 4 and the bottom plate 2, which is used to drive the rotating side plate to rotate outward to the feeding state. Further, the FPC folding and testing integrated carrier 200 also includes a rotating hook plate 702, a fixing block 703, and a hook plate spring. The middle part of the rotating hook plate 702 is hinged to the rotating cover plate 3; the fixing block 703 is fixed to the rotating side plate 4; the hook plate spring is located between one end of the rotating hook plate 702 and the top surface of the rotating cover plate 3, and is used to drive the other end of the rotating hook plate 702 to rotate and engage with the fixing block 703, so that the rotating side plate 4 maintains the folding state. Therefore, as long as the elastic force of the hook plate spring is overcome, pressing down the end of the rotating hook plate 702 away from the fixing block 703 will cause the side plate torsion spring 701 to drive the rotating side plate 4 to rotate automatically outward, facilitating the opening of the rotating side plate.

[0091] Furthermore, the rotating side plate 4 is provided with a transfer needle slot 403 at the position corresponding to the transfer plate 101, and the first bending clearance groove 401 is provided with a first needle slot 404 at the position corresponding to the first flexible circuit board 102. Therefore, electrical connection with the transfer plate 101 can be achieved through the transfer needle slot 403, and electrical connection with the first flexible circuit board 102 can be achieved through the first needle slot 404.

[0092] See Figure 4 and Figure 5 In this embodiment, the inclined push assembly 5 is slidably connected to the rotating cover plate 3, and is used to cooperate with the second bending clearance groove 402 to bend the second flexible circuit board 103, so that the second flexible circuit board 103 forms a second bending point 1031. Further, the inclined push assembly 5 is used to bend the second flexible circuit board 103 into an L-shape, that is, the end of the bent second flexible circuit board 103 away from the transfer plate 101 will extend to the outside of the FPC bending and testing integrated carrier 200 through the second bending clearance groove 402.

[0093] Specifically, the rotating cover plate 3 has a downwardly recessed inclined groove 301 at the top corner near the rotating side plate, and the side of the rotating cover plate 3 has an inclined connecting groove 302 that connects to the inclined groove 301 at the position corresponding to the second bending clearance groove 402.

[0094] The inclined push assembly 5 includes an inclined sliding lever 501, an inclined push block 502, and an inclined push return spring 503. The upper part of the inclined sliding lever 501 is located above the inclined slide groove 301, and the middle part is slidably installed in the inclined slide groove 301. The inclined push block 502 is located in the inclined connecting groove 302 and is fixedly connected to the lower end of the inclined sliding lever 501. The inclined push return spring 503 is located on the side of the inclined push block 502 near the second bending clearance groove 402, and is used to drive the inclined push block 502 to slide away from the second bending clearance groove 402.

[0095] Normally, the inclined push return spring 503 drives the inclined push block 502 away from the second bending clearance groove 402. When it is necessary to bend the second flexible circuit board 103, the inclined slide lever 501 is manually pushed forward to overcome the elastic force of the inclined push return spring 503. The inclined slide lever 501 then drives the inclined push block 502 to extend forward, thereby bending the straight second flexible circuit board 103 into an L-shape. After releasing the lever, the inclined push return spring 503 drives the inclined push block 502 away from the second bending clearance groove 402, which allows the inclined slide lever 501 and the inclined push block 502 to automatically return to their original positions.

[0096] See Figure 6 and Figure 7The lateral push assembly 6 is slidably connected to the rotating cover plate 3, and is used to cooperate with the first bending clearance groove 401 to bend the first flexible circuit board 102, so that the first flexible circuit board 102 forms a first bending point 1021. Further, the lateral push assembly 6 is used to bend the first flexible circuit board 102 into a Z-shape.

[0097] In this embodiment, the top surface of the rotating cover plate 3 is provided with a downwardly recessed transverse groove 303 at the middle position. The side surface of the rotating cover plate 3 is provided with a first transverse connecting groove 304 corresponding to the first bending clearance groove 401. The side surface of the rotating cover plate 3 is also provided with a second transverse connecting groove 305 corresponding to the second bending clearance groove 402.

[0098] The horizontal push assembly 6 includes a horizontal push plate 601, a first horizontal push rod 602, a horizontal return spring 603, and a second horizontal push rod 604.

[0099] The upper part of the transverse push plate 601 protrudes above the transverse sliding groove 303, and the lower part is slidably installed in the transverse sliding groove 303. The first transverse push rod 602 is located in the first transverse connecting groove 304 and is fixedly connected to the lower end of the transverse push plate 601. The transverse return spring 603 is located on the side of the transverse push plate 601 near the first bending clearance groove 401, and is used to drive the first transverse push rod 602 to slide away from the first bending clearance groove 401. The second transverse push rod 604 is located in the second transverse connecting groove 305 and is fixedly connected to the lower end of the transverse push plate 601.

[0100] Understandably, after the inclined push return spring 503 drives the inclined slide lever 501 and the inclined push block 502 to automatically reset, the horizontal push plate 601 is pushed forward against the elastic force of the horizontal return spring 603, thus achieving the desired result.

[0101] On the one hand, the end of the first transverse push rod 602 is driven to press the first flexible circuit board 102 into the first bending relief groove 401, thereby bending the first flexible circuit board 102 into a Z shape.

[0102] On the other hand, the end of the second lateral push rod 604 is driven to pass through the second bending clearance groove 402, and the second lateral push rod 604 abuts against the side of the second flexible circuit board 103, thereby keeping the second flexible circuit board 103 in an L-shaped state.

[0103] Furthermore, the side of the transverse slide groove 303 is provided with a longitudinal slide groove 306 communicating with the transverse slide groove 303. The longitudinal slide groove 306 is provided with a limiting slider 801 and a limiting spring 802. The upper part of the limiting slider 801 is located above the longitudinal slide groove 306, and the lower part is slidably installed in the longitudinal slide groove 306. The limiting spring 802 is located on the side of the limiting slider 801 away from the transverse slide groove 303, and is used to drive the limiting slider 801 to slide towards the transverse slide groove 303.

[0104] When the transverse push plate 601 is not pushed forward, the end face of the limiting slider 801 abuts against the side of the transverse push plate 601. Therefore, the limiting slider 801 is blocked by the transverse push plate 601 and cannot smoothly extend into the transverse slide groove 303. When the transverse push plate 601 is pushed forward, the transverse push plate 601 moves to a forward position, and the side of the transverse push plate 601 can no longer abut against the limiting slider 801. Under the driving action of the limiting spring 802, the end of the limiting slider 801 extends into the transverse slide groove 303 and moves to the rear of the transverse push plate 601. At this time, even if the transverse push plate 601 is released, due to the blocking effect of the limiting slider 801 on the transverse push plate 601, the transverse reset spring 603 cannot make the transverse push plate 601 slide back to reset. As a result, the first transverse push rod 602 continues to press the first flexible circuit board 102 forward and the second transverse push rod 604 presses the second flexible circuit board 103 laterally.

[0105] When it is necessary to remove the FPC circuit assembly 1, the elastic force of the limit spring 802 must be overcome first, and the limit slider 801 must be pushed back. Once the limit slider 801 is pushed back, the transverse reset spring 603 can drive the transverse push plate 601 to slide back and reset. Then, press the rotating hook plate 702 to open the rotating side plate and the rotating cover plate 3, and finally remove the FPC circuit assembly 1.

[0106] Secondly, see Figure 8 This embodiment provides a testing device, including a testing machine 100, several FPC bending and testing integrated carriers 200, a rotating pressure plate 300, and an electrical connection assembly 400.

[0107] Each of the FPC folding and testing integrated carriers 200 is magnetically connected to the testing machine 100; the rotating pressure plate 300 is hinged to the testing machine 100 and is used to press each of the FPC folding and testing integrated carriers 200 downwards. Specifically, a pressure plate torsion spring can be provided at the hinge position of the rotating pressure plate 300, and the torsion of the pressure plate torsion spring drives the rotating pressure plate 300 to press each of the FPC folding and testing integrated carriers 200 downwards; or, a pressure cylinder can be provided above the rotating pressure plate 300, and when the rotating pressure plate 300 is manually rotated above the FPC folding and testing integrated carrier 200, the driving end of the pressure cylinder extends downwards, thereby driving the rotating pressure plate 300 to press the FPC folding and testing integrated carrier 200 downwards.

[0108] The electrical connection assembly 400 is mounted on the test bench 100 and is used to electrically connect with the FPC circuit assembly 1 in the FPC folding and testing integrated carrier 200.

[0109] In this embodiment, see Figure 9 and Figure 10 The electrical connection assembly 400 includes a third probe assembly 901, wherein the third probe assembly 901 is fixed at the position of the test platform 100 for mounting the FPC folding and testing integrated carrier 200. That is, when the rotating pressure plate 300 presses down the FPC folding and testing integrated carrier 200 magnetically mounted on the test platform 100, the third probe assembly 901 can be electrically connected to the adapter 201 on the base plate 2, thereby performing electrical function testing on the third flexible circuit board 104.

[0110] The electrical connection assembly 400 also includes a main needle insertion plate 902, a transfer probe assembly 903, a first probe assembly 904, a main needle insertion cylinder 905, a secondary needle insertion cylinder 906, a secondary needle insertion plate 907, and a second probe assembly 908.

[0111] The main probe plate 902 is located on the side of the FPC folding and testing integrated carrier 200; the transfer probe assembly 903 and the first probe assembly 904 are both fixed on the main probe plate 902; the drive end of the main probe cylinder 905 is connected to the main probe plate 902. When the drive end of the main probe cylinder 905 is in the extended state, the transfer probe assembly 903 can be driven to insert into the transfer probe slot 403 of the FPC folding and testing integrated carrier 200 and be electrically connected to the transfer plate 101, and the first probe assembly 904 can be inserted into the first probe slot 404 of the FPC folding and testing integrated carrier 200 and be electrically connected to the first flexible circuit board 102, thereby realizing the electrical function testing of the transfer plate 101 and the first flexible circuit.

[0112] The auxiliary needle insertion cylinder 906 is mounted on the main needle insertion cylinder 905, and the driving direction of the auxiliary needle insertion cylinder 906 is perpendicular to the driving direction of the main needle insertion cylinder 905; the auxiliary needle insertion plate 907 is fixedly connected to the driving end of the auxiliary needle insertion cylinder 906; the second probe assembly 908 is fixedly connected to the auxiliary needle insertion plate 907, and after being driven by the auxiliary needle insertion cylinder 906, it is electrically connected to the second flexible circuit board 103 in the FPC circuit assembly 1.

[0113] The end of the second flexible circuit board 103 away from the transfer plate 101 is bent to the outside of the FPC folding and testing integrated carrier 200. Therefore, when the drive end of the main needle cylinder 905 is in the extended state, the second probe assembly 908 just moves to the side of the end of the second flexible circuit board 103 that is bent to the outside of the FPC folding and testing integrated carrier 200. Therefore, when the drive end of the auxiliary needle cylinder 906 retracts, the second probe assembly 908 can approach and press the second flexible circuit board 103, thereby realizing the electrical function detection of the second flexible circuit board 103.

[0114] The testing equipment provided in this embodiment operates as follows:

[0115] S101: At the beginning, the base plate 2, the rotating cover plate 3 and the rotating side plate 4 are in a horizontal state;

[0116] At this time, the rotating side plate 4 is in the feeding state;

[0117] S102: Place the unbent FPC circuit assembly 1 into the FPC bending and testing integrated carrier 200;

[0118] Specifically, the third flexible circuit board 104 is placed on the base plate 2, and the transfer plate 101, the first flexible circuit board 102 and the second flexible circuit board 103 are placed on the rotating side plate 4.

[0119] S103: Rotate the rotating cover plate 3 so that the rotating cover plate 3 cooperates with the base plate 2 to press the third flexible circuit board 104;

[0120] S104: Rotate the rotating side plate 4 so that the rotating side plate 4 drives the central plate 101, the first flexible circuit board 102 and the second flexible circuit board 103 to rotate together to a vertical position.

[0121] At this time, the rotating side plate enters the folding state, and the third flexible circuit board 104 is bent near the transfer plate 101, forming the third bending point 1041.

[0122] Furthermore, the rotating hook plate 702 hooks onto the fixing block 703, so that the rotating side plate 4 remains in the folded state;

[0123] S105: Overcome the elastic force of the inclined push return spring 503, push the inclined slide lever 501 forward, thereby causing the inclined push block 502 to extend forward and bend the second flexible circuit board 103 into an L shape (the end of the second flexible circuit board 103 away from the central plate 101 extends to the outside of the rotating side plate 4 through the second bending clearance groove 402).

[0124] The second flexible circuit board 103 is bent at the position where it fits against the edge of the second bending relief groove 402, forming the second bending point 1031.

[0125] S106: Overcoming the elastic force of the transverse return spring 603, the transverse push plate 601 is pushed forward, and the first transverse push rod 602 extends into the first bending clearance groove 401, thereby causing the first flexible circuit board 102 to bend and form the first bending point 1021; at the same time, the second transverse push rod 604 extends into the second bending clearance groove 402, and laterally presses the second flexible circuit board 103, so that the second flexible circuit board 103 maintains an L-shaped shape;

[0126] S107: The limiting spring 802 drives the limiting slider 801 to extend behind the transverse push plate 601, so that the transverse push plate 601 remains in the forward-pushing state.

[0127] At this point, the bending operation of FPC circuit component 1 can be completed; next, the electrical function testing operation will be performed:

[0128] S201: The FPC folding and testing integrated carrier 200, which is loaded with FPC circuit component 1, is placed on the test machine 100. The relative positioning of the FPC folding and testing integrated carrier 200 and the test machine 100 is quickly achieved through magnetic attraction, thereby aligning the adapter 201, which is electrically connected to the third flexible circuit board 104, with the third probe component 901.

[0129] S202: Press the rotating pressure plate 300 downward to press the FPC folding and testing integrated carrier 200, thereby making the adapter 201 fully contact the third probe assembly 901;

[0130] S203: The drive end of the main needle cylinder 905 extends, driving the transfer probe assembly 903 to be inserted into the transfer needle slot 403 of the FPC folding and testing integrated carrier 200 and electrically connected to the transfer plate 101; the first probe assembly 904 is inserted into the first needle slot 404 of the FPC folding and testing integrated carrier 200 and electrically connected to the first flexible circuit board 102.

[0131] S204: The drive end of the auxiliary needle cylinder 906 retracts, causing the second probe assembly 908 to approach and press against the second flexible circuit board 103.

[0132] S205: Start the test circuit board to test the electrical functions of the transfer board 101, the first flexible circuit board 102, the second flexible circuit board 103, and the third flexible circuit board 104;

[0133] After testing, FPC circuit component 1 needs to be removed. The process is as follows:

[0134] S301: Open the rotating pressure plate 300;

[0135] S302: Remove the FPC folding and testing integrated carrier 200 from the testing machine 100;

[0136] S303: Overcoming the elastic force of the limiting spring 802, the limiting slider 801 is pushed backward, and the transverse push plate 601 automatically slides backward and resets under the drive of the transverse reset spring 603, and the first transverse push rod 602 and the second transverse push rod 604 retract synchronously.

[0137] S304: Overcome the elastic force of the hook plate spring, press the rotating hook plate 702 in detail, and the side plate torsion spring 701 will drive the rotating side plate to rotate outward automatically to the feeding state. Open the rotating cover plate 3 to take out the FPC circuit assembly 1.

[0138] The FPC integrated testing and testing vehicle 200 and testing equipment provided in this embodiment have the following advantages:

[0139] ① Before installing the FPC circuit assembly 1 into the housing, the electrical function of the FPC circuit assembly 1 can be tested under bending conditions. If the test finds that the FPC circuit assembly 1 is defective, it can be directly sorted out and will not be installed into the housing, which helps to reduce production costs.

[0140] Furthermore, if the FPC circuit assembly is first bent on the bending equipment, and then taken out from the bending equipment and placed on a conveyor belt or other conveying device to be transferred to the testing equipment, there are many uncertainties in the transmission process. For example, the bending point on the FPC circuit assembly may spring back, making it difficult to guarantee the positioning accuracy, which increases the difficulty of the subsequent testing station.

[0141] The FPC bending and testing integrated carrier provided in this embodiment is used to bend the FPC circuit component inside the FPC bending and testing integrated carrier. Then, the FPC bending and testing integrated carrier with the bent FPC circuit component is placed into the testing equipment for testing. During the bending test, the FPC circuit component is always inside the FPC bending and testing integrated carrier. The position of the FPC circuit component is fixed, which makes it easy to ensure accuracy and reduce the difficulty of test alignment.

[0142] ② The oblique push component 5 is positioned at the top corner of the rotating cover plate 3, and the horizontal push component 6 is positioned at the middle of the rotating cover plate 3. Then, the oblique push component 5 is first bent at the second bending point 1031, and then the horizontal push component 6 is used to bend at the first bending point 1021. This can avoid interference between the oblique push component 5 and the horizontal push component 6, and can also minimize the volume of the rotating cover plate 3 and improve the structural compactness.

[0143] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0144] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
