Description

Technical Field

[0001] The utility model belongs to the technical field of FPC testing, and particularly relates to a flip - type FPC testing fixture. Background Art

[0002] In modern electronic manufacturing, flexible printed circuit boards (FPCs) are widely used in various electronic devices due to their high flexibility and adaptability. However, during the production process of FPCs, functional testing is a necessary step to ensure that their electrical performance meets the design requirements. For some specially designed FPCs, such as those with double - sided connectors (i.e., connectors are equipped at both ends of the FPC, but the connectors are on different sides of the FPC), the testing process becomes particularly complex.

[0003] Traditional testing methods usually involve manually aligning and connecting the connectors of the FPC with the corresponding interfaces on the testing equipment. However, for double - sided connector FPCs, since the connectors are on different sides of the FPC, the tester needs to first connect the connectors on one side and then flip the FPC to connect the connectors on the other side. This operation method is not only inefficient but also likely to damage the FPC during the flipping process, especially when dealing with small and precise FPCs, the risk is even higher.

[0004] Therefore, there is an urgent need for a flip - type FPC testing fixture that can improve testing efficiency and reduce the risk of FPC damage. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a flip - type FPC testing fixture aiming at the deficiencies of the prior art, which can perform continuity testing on FPCs with double - sided connectors, can accommodate the connectors on both sides of the FPC at the same time, improves the testing efficiency of the FPC, and reduces the risk of FPC damage.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A flip - type FPC testing fixture, comprising:

[0008] A machine table;

[0011] A first extrusion mechanism is also provided on the first plate surface. The first extrusion mechanism is close to the operation port and located on the opposite side of the lower die assembly, and is used to extrude the first connector and the lower die assembly to conduct. A second connector corresponding to the FPC to be tested is provided on the upper die assembly of the first extrusion mechanism.

[0012] A second extrusion mechanism is installed on the second plate surface and is used to extrude the second connector and the upper die assembly to conduct.

[0015] Furthermore, a first magnet and a second magnet that attract each other are provided on the flip cover plate and the fixed seat.

[0016] Furthermore, a translation guide rail is provided below the first extrusion mechanism. The translation guide rail is used to move the first extrusion mechanism and the upper die assembly closer to or farther away from the operation port.

[0017] Furthermore, a moving plate is provided on the first extrusion mechanism. A first baffle and a second baffle are provided on the first plate surface. When the first extrusion mechanism moves on the translation guide rail, the moving plate moves between the first baffle and the second baffle.

[0034] Refer to the attached Figure 1 to the attached Figure 5 , which shows a specific embodiment of a flip - type FPC test fixture provided by the present utility model.

[0035] Refer to the attached Figure 1 and the attached Figure 2 , the flip - type FPC test fixture includes:

[0036] A machine table 1;

[0037] A flip - plate 2 rotatably arranged on the machine table 1, including a first plate surface 210 and a second plate surface 220, and an operation opening 230 is provided on the flip - plate 2;

[0038] The lower die assembly 3 is provided on the first plate surface 210. On one side of the lower die assembly 3 close to the operation opening 230, a first connector 910 for placing the FPC 9 to be tested is provided.

[0039] The first pressing mechanism 4 is also provided on the first plate surface 210. The first pressing mechanism 4 is close to the operation opening 230 and is located on the opposite side of the lower die assembly 3, and is used to press the first connector 910 and the lower die assembly 3 to conduct. A second connector 920 corresponding to the FPC 9 to be tested is provided on the first pressing mechanism 4 and corresponds to the upper die assembly 5.

[0040] The second pressing mechanism 6 is installed on the second plate surface 220 and is used to press the second connector 920 and the upper die assembly 5 to conduct.

[0041] Refer to the appendix Figure 3 In the above embodiment, a control mechanism is provided in the machine table 1 to realize the control of the overall test process. The flip plate 2 is suspended on the machine table 1, and its first plate surface 210 or the second plate surface 220 can be turned upwards through flipping. The operation opening 230 is located at the middle position of the flip plate 2, which is used to conveniently pick and place the FPC 9 to be tested and enable the second pressing mechanism 6 on the back side to touch the FPC 9 to be tested on the other side through the operation opening 230. In the embodiment, both the upper die assembly 5 and the lower die assembly 3 are provided with a floating probe structure. When in use, first place the first connector 910 of the FPC 9 to be tested downwards on the lower die assembly 3 and fix it. The other end of the FPC 9 to be tested is suspended above the operation opening 230, and the second connector 920 of the FPC 9 to be tested faces upwards; then, operate the first pressing mechanism 4 to press down on the lower die assembly 3. At this time, due to the extrusion, the first connector 910 contacts and conducts with the probe in the lower die assembly 3, and at the same time the lower die assembly 3 approaches the second connector 920; then rotate the flip plate 2 to make the flip plate 2 in a vertical state or the second plate surface 220 face upwards, and confirm that the second connector 920 is accurately aligned with the upper die assembly 5; finally, operate the second pressing mechanism 6, and the second connector 920 is pressed to contact and conduct with the probe in the upper die assembly 5, thereby completing the positioning, connection and testing of the FPC 9 to be tested.

[0042] Refer to the appendix Figure 4 In the above embodiment, a pre-pressing mechanism 7 is further provided close to the lower die assembly 3. The pre-pressing mechanism 7 is used to pre-press the FPC 9 to be tested placed on the lower die assembly 3. In the embodiment, after the first connector 910 of the FPC 9 to be tested is placed on the lower die assembly 3, in order to make one end of the second connector 920 of the FPC 9 to be tested able to be suspended at the operation opening 230, in this embodiment, the pre-pressing mechanism 7 is used to pre-press the FPC 9 to be tested at the lower die assembly 3 to make the FPC 9 to be tested relatively fixed with the lower die assembly 3. At this time, the first connector 910 and the probe in the lower die assembly 3 are in a non-conducting state.

[0043] Refer to the appendixFigure 4 In the above embodiment, the pre-pressing mechanism 7 includes a flip cover seat 710 and a fixed seat 720, and a flip cover plate 730 rotatably arranged on the flip cover seat 710. The lower die assembly 3 is located between the flip cover seat 710 and the fixed seat 720. When the flip cover plate 730 rotates onto the fixed seat 720, it will pre-press the FPC 9 to be tested. In the embodiment, the pre-pressing mechanism 7 is of a flip type structure. One end of the flip cover plate 730 rotates on the flip cover seat 710, and when the other end is connected to the fixed seat 720, it is in the pre-pressing state. When it is rotated and opened, the FPC 9 to be tested can be placed and taken.

[0044] Refer to the appendix Figure 4 In the above embodiment, a first magnet 731 and a second magnet 721 that attract each other are provided on the flip cover plate 730 and the fixed seat 720. In the embodiment, the mutually attracting first magnet 731 and second magnet 721 achieve the relative fixation between the flip cover plate 730 and the fixed seat 720, enabling the tester to conveniently open or close the flip cover plate 730 and improving the testing efficiency. Optionally, magnets can also be provided on the opposite side of the flip cover seat 710 and the fixed seat 720 to facilitate restricting the position of the flip cover plate 730 after it is opened.

[0045] Refer to the appendix Figure 3 In the above embodiment, a translation guide rail 8 is provided below the first pressing mechanism 4. The translation guide rail 8 is used to move the first pressing mechanism 4 and the upper die assembly 5 closer to or farther away from the operation port 230. In the embodiment, when the translation guide rail 8 approaches the operation port 230, the extrusion test process can be entered; when the translation guide rail 8 moves away from the operation port 230, the space at the operation port 230 will be vacated, facilitating the tester to place and take out the FPC 9 to be tested at the operation port 230 and improving the operation convenience.

[0046] Refer to the appendix Figure 3 In the above embodiment, a moving plate 410 is provided on the first pressing mechanism 4, and a first baffle 211 and a second baffle 212 are provided on the first plate surface 210. When the first pressing mechanism 4 moves on the translation guide rail 8, the moving plate 410 moves between the first baffle 211 and the second baffle 212. In the embodiment, the moving plate 410 is fixed on the first pressing mechanism 4 and moves together with the first pressing mechanism 4. The first baffle 211 and the second baffle 212 limit the moving range of the first pressing mechanism 4, ensuring the safety of the testing process.

[0047] Refer to the appendix Figure 3In the above embodiment, the third magnet 411 is provided on the moving plate 410, and the fourth magnet 2111 and the fifth magnet 2121 are provided on the first baffle 211 and the second baffle 212, respectively. When the moving plate 410 approaches the first baffle 211 or the second baffle 212, the third magnet 411 will be attracted to the fourth magnet 2111 or the fifth magnet 2121. In the embodiment, the first squeezing mechanism 4 moves in a direction away from the operation port 230. When the moving plate 410 moves to approach the first baffle 211, the third magnet 411 of the moving plate 410 will be attracted to the fourth magnet 2111 of the first baffle 211, so that the first squeezing mechanism 4 is relatively fixed away from the operation port 230. When the first squeezing mechanism 4 moves toward the operating port 230 and the movable plate 410 moves to the second baffle plate 212 , the third magnet 411 of the movable plate 410 will attract the fifth magnet 2121 of the second baffle plate 212 , thereby achieving relative fixation of the first squeezing mechanism 4 near the operating port 230 .

[0048] See attached Figure 5 In the above embodiment, the first extrusion mechanism 4 includes an extrusion seat 420 installed on the translation guide rail 8, a horizontal pressure elbow clamp 430 installed on the upper end of the extrusion seat 420, and an extrusion plate 440 movably connected to the horizontal pressure elbow clamp 430, and the upper mold assembly 5 is installed below the extrusion plate 440. In the embodiment, when the horizontal pressure elbow clamp 430 is bent, the horizontal pressure elbow clamp 430 pushes the horizontally arranged extrusion plate 440 to move downward, and the upper mold assembly 5 installed below the extrusion plate 440 also moves downward synchronously. In the embodiment, the second extrusion mechanism 6 is a horizontal elbow clamp. When the second extrusion mechanism 6 is operated, the output end of the horizontal elbow clamp passes through the operation port 230 on the flip plate 2 and enters the side where the first board surface 210 is located, and then abuts against the back of the second connector 920 of the FPC 9 to be tested and squeezes the second connector 920 toward the upper mold assembly 5, so as to realize the conduction test between the second connector 920 and the upper mold assembly 5.

[0049] See attached Figure 1 and attached Figure 2 In the above embodiment, brackets 110 are provided at both ends of the machine 1, and the flip plate 2 is mounted on the brackets 110 through the damping shaft 120. In the embodiment, the flip plate 2 is mounted on the brackets through the damping shaft 120, so that the flipping operation of the flip plate 2 is smoother and more stable, which improves the convenience of operation and the durability of the fixture.

[0050] In summary, this embodiment provides a flip-type FPC test fixture. By setting the flip plate 2 that can be flipped, it is possible to test the double-sided connectors of the FPC on the same fixture without flipping the FPC, which improves the test efficiency and reduces the risk of damage. Through the setting of the preloading mechanism 7, preloading of the FPC 9 to be tested placed on the lower die assembly 3 is achieved. Through the setting of the translation guide rail 8, flexible movement of the first extrusion mechanism 4 and the upper die assembly 5 is realized, facilitating the placement and removal of the FPC 9 to be tested and improving the convenience of operation. By setting the first baffle 211 and the second baffle 212, the movement range of the moving plate 410 is restricted to limit the movement range of the first extrusion mechanism 4, ensuring the safety of the test process. This embodiment can achieve continuity testing of the FPC with double-sided connectors, can accommodate the two-sided connectors of the FPC simultaneously, improves the test efficiency of the FPC, and reduces the risk of damage to the FPC.
