Description

Technical Field

[0001] This utility model relates to the field of flexible circuit board technology, specifically to a device for testing the insertion and removal life of carbon sheets on flexible circuit boards. Background Technology

[0002] Flexible circuit boards are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bending performance.

[0003] In practical use, the carbon sheets on flexible circuit boards are mainly used for plug-in connections. After repeated plugging and unplugging, the tightness of the connection will be damaged, and the connection is prone to loosening. Currently, no plugging and unplugging life test is performed before use, so the number of plugging and unplugging times cannot be predicted. The damage can only be known after a problem occurs, which affects the safety of the actual use environment.

[0004] Therefore, a flexible circuit board carbon sheet insertion and removal life testing device is proposed to solve the problems mentioned above. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1 - Figure 4 The flexible circuit board carbon sheet insertion and removal life testing device in this embodiment includes a testing platform 1, a display screen 201 installed on the upper end of the testing platform 1, and an emergency stop button 2 provided on the side of the testing platform 1.

[0028] The upper end of the testing table 1 is equipped with an X-axis drive motor 3 and a Z-axis drive motor 15 for drive support, a transmission bolt 4 and a transmission rod 14 for transmission support. The transmission bolt 4 and the transmission rod 14 are vertically distributed. The outer side of the transmission bolt 4 is threaded with a product placement table 6. The lower end of the transmission rod 14 is fixedly connected to a connector 12. A test head 10 is set below the connector 12.

[0029] Test head 10 is used for pressing;

[0030] Product placement platform 6 is used for support;

[0031] The device's overall operation is controlled by using the display screen 201, and the device can be stopped in time by using the emergency stop button 2. This control method can directly control the device through programming or other predetermined programs. Since this control method is a well-known technology in the field, it is not described in detail in this embodiment.

[0032] By placing the flexible circuit board carbon sheet on the product placement platform 6, the X-axis drive motor 3 is started, and driven by the transmission bolt 4, it moves downward to the Z-axis drive motor 15. When one end of the flexible circuit board carbon sheet moves below the test head 10, the Z-axis drive motor 15 is started, and driven by the transmission rod 14, the test head 10 moves downward and gradually presses the flexible circuit board carbon sheet. When the pressing force reaches the required level, the X-axis drive motor 3 is controlled to rotate in the opposite direction, causing the product placement platform 6 to move in the opposite direction and pulling the flexible circuit board carbon sheet in the opposite direction, so that it is displaced from the clamping part of the test head 10. Finally, the effect of insertion and removal testing is achieved. By setting the number of reciprocating movements and the magnitude of the pressing and clamping force, the effect of insertion and removal life testing of the flexible circuit board carbon sheet can be achieved.

[0033] The control of both the Z-axis drive motor 15 and the X-axis drive motor 3 can be achieved through existing controllers, and the use of such controllers is well-known to those skilled in the art. Therefore, it is not described in detail in this embodiment.

[0034] The transmission bolt 4 is installed at the output end of the X-axis drive motor 3, and the lower half of the product placement platform 6 is inserted into the inside of the testing platform 1.

[0035] A fixing frame 7 is provided above the product placement platform 6. Adjusting bolts 8 are threadedly connected to both sides of the upper end of the fixing frame 7. The adjusting bolts 8 extend into the interior of the product placement platform 6 and are threadedly connected to the product placement platform 6.

[0036] By limiting the product placement platform 6 with the test bench 1, the rotation of the transmission bolt 4 drives the product placement platform 6 to rotate synchronously, ensuring that the product placement platform 6 has the effect of horizontal movement under the threaded connection with the transmission bolt 4. By rotating the adjusting bolt 8, the contact space between the fixing frame 7 and the product placement platform 6 is tightened, forming a clamping force on the carbon sheet of the flexible circuit board, preventing it from slipping when pulled, and ensuring the accuracy and reliability of its plug-in and unplugging test.

[0037] The upper end of the testing table 1 is provided with a vertical plate 5 for fixing the Z-axis drive motor 15, and one end of the transmission bolt 4 is rotatably set on one side of the vertical plate 5.

[0038] The transmission rod 14 is fixedly installed at the output end of the Z-axis drive motor 15, and a sensor connector 11 is provided at the lower end of the connector 12. The sensor connector 11 is installed on the upper end of the test head 10.

[0039] A limit connector 13 is provided on the side of the connector 12, and the sensing connector 11 is connected to the external pressure sensor via a cable;

[0040] A support plate 9 is provided on the lower half of the side of the vertical plate 5. The support plate 9 is located below the test head 10, and there is a clamping and positioning space between the test head 10 and the support plate 9.

[0041] Driven by the Z-axis drive motor 15 and the transmission rod 14, the connector 12, sensor connector 11, and test head 10 are pushed down synchronously. With the support of the support plate 9, the carbon sheet is pressed. Through the connection between the sensor connector 11 and the external pressure sensor, the magnitude of the pressing force can be obtained in time, ensuring the accuracy of the test results. Under the limit detection of the limit connector 13, the pressing overload is prevented, which would lead to inaccurate test results.

[0042] A clamping and positioning space is provided between the support plate 9 and the test head 10 to provide a placement space for the carbon sheet for testing, ensuring the accuracy of its testing position and thus improving the overall reliability of the device during testing.

[0043] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
