Description

Technical Field

[0001] The present application relates to the technical field of flexible flat cable detection equipment, and in particular to a flexible flat cable detection device. Background Art

[0002] The statements in this section merely provide background technical information related to this application and do not necessarily constitute prior art.

[0003] Flexible flat cable, FFC in English, is widely used in the field of electronic equipment due to its good flexibility and small space. Currently, factory inspections for flexible flat cables include: first, inspection of the cable's external dimensions. For example, the inspection device disclosed in patent application number CN201420852840.6, entitled "Flexible Flat Cable Inspection Device," can conveniently and intuitively display whether the cable's end dimensions meet precision requirements, effectively preventing defective products from being passed to the next process. Second, inspection of the cable's flatness and solderability of solder joints. For example, patent application number CN201820799295.7, entitled "A Flexible Flat Cable Inspection Device," includes a flatness inspection mechanism installed on a partition in the middle of the housing, and a solder joint inspection mechanism installed on one side of the flatness inspection mechanism, effectively inspecting the cable's flatness and solderability. Third, a detection circuit is used to detect whether there are breakpoints in the flat copper foil inside the cable or short circuits between the copper foils. This technology is currently relatively mature.

[0004] However, in practical applications, it has been found that if the spacing dimensions of the flat copper foil at the connectors on both ends of the flexible flat cable do not meet the requirements, it will also have a significant impact on the use of the product. Because the connectors at both ends of the flexible flat cable often have specific sockets or connectors, the spacing of the flat copper foil at the connectors must meet the requirements to ensure that each flat copper foil corresponds to a specific circuit. When there is an error in the spacing of the flat copper foil, the connection between the flat copper foil and the circuit will be unstable, the contact area will be small, or there will be no contact at all. This is a serious hidden danger for electronic circuits. Poor circuit contact can easily cause heat, resulting in damage or even direct unusability.

[0005] Based on the previous analysis of existing technologies, there is currently no reliable and mature device or method for detecting the spacing size of the flat copper foil at the connectors at both ends of flexible flat cables. Furthermore, during the production process of flexible flat cables, there is also a lack of means to detect the spacing size of the flat copper foil at the connectors at both ends of the flexible flat cables. If the spacing size of the flat copper foil does not meet the requirements, it will result in a large number of waste or defective products. Therefore, it is necessary to design a flexible flat cable inspection device that can detect the spacing size of the flat copper foil at the connectors at both ends of the flexible flat cable.

[0077] A method for detecting the spacing between flat copper foils of a flexible flat cable connector comprises the following steps:

[0078] A: Connect the flexible flat cable.

[0079] First, the servo motor 43 is controlled by the control device to rotate so that the detection mechanism 5 is placed on the left side of the platform 4;

[0080] Then, press the pressure rod 24 to lift the pressing roller 23, and insert the flexible flat cable front connector 30 from under the pressing roller 23 until the front and right side of the flexible flat cable connector are placed in the corner of the platform 4 and the side guard 40.

[0083] For example, t0 is the duration of the first digital input channel being on, t1 is the duration of the first digital input channel being on, ······, t n The duration of the nth digital input channel being on. In some embodiments, the control device is a PLC, and the digital input channel of the PLC is an I / O port. When actually collecting the duration of each I / O port being on, the PLC can collect the time from the rising edge of the corresponding I / O port signal to the falling edge of the signal;

[0084] C: The control device performs the following operations on the data in step B:

[0085] S0=V*t0;

[0086] S1=V*t1;

[0087] S2=V*t2;

[0088] ···

[0089] S n =V*t n ;

[0091] N0=|N-S0|;

[0092] N1=|N-S1|;

[0093] N2=|N-S2|;

[0094] ···

[0095] N n =|NS n |;

[0096] Then N0, N1, N2, ···, N n The value of is compared with the error threshold Q set by the control device one by one. If N0, N1, N2, ···, N n If the values ​​of are all less than the error threshold Q set by the control device, it is determined that the spacing between the flat copper foils of the flexible flat cable is qualified, and step D is performed;

[0097] If N0, N1, N2, ···, N n If at least one of the values ​​is greater than the error threshold Q set by the control device, it is determined that the spacing between the flat copper foils of the flexible flat cable is unqualified, and the control device issues an alarm through the built-in alarm module, and then proceeds to step E;

[0098] The standard spacing N set for the flat copper foil 310 of the flexible flat cable is the standard requirement for the spacing of the flat copper foil 310 of the flexible flat cable in actual production. When the spacing between the two flat copper foils 310 exceeds or is less than the standard spacing N, it is considered unqualified. Considering that there may be errors in practice, S0, S1, S2, . . . , S n The spacing is compared with the standard spacing N set for the flat copper foil 310 of the flexible flat cable. As long as it does not exceed the error threshold Q set by the control device, the spacing is within the error range and the spacing of the flat copper foil of the flexible flat cable is determined to be qualified. Otherwise, it is unqualified.

[0099] D: The servo motor 43 is controlled to rotate by the control device so that the detection mechanism 5 is placed on the left side of the platform 4;

[0100] Then, press the pressure rod 24 to lift the pressing roller 23, remove the front connector 30 of the flexible flat cable from under the pressing roller 23, and then insert the rear connector 31 of the flexible flat cable from under the pressing roller 23 until the front and right side of the rear connector 31 of the flexible flat cable are placed in the corner of the platform 4 and the side guard 40. Then, release the pressure rod 24, and the pressing roller 23 presses the flexible flat cable.

[0101] Finally, connect the flat copper foils 310 at the front connectors 30 of the flexible flat cable to the digital input channels of the control device one by one, and then proceed to step B;

[0102] E: Replace the next flexible flat cable and go to step A.

[0103] In some embodiments, in order not to damage the front connector 30 and the rear connector 31 of the flexible flat cable to be inspected, a connector is added, such as an FPC / FFC connector, one connector of the flexible flat cable is inserted into the FPC / FFC connector, and the connection terminals at the other end of the FPC / FFC connector are connected to the control device through lines; for example, the FPC / FFC connector of model FH52-15S-0.5SH (99) is used.

[0104] The present invention relates to a flexible flat cable connection device that controls a servo motor to rotate at a constant speed via a control device. By recording the time the control device's switch is on, the device calculates the spacing between the flat copper foils at the connectors at both ends of the flexible flat cable. This calculation, performed via electrical signals, is accurate and reliable. The detection utilizes contact between a metal spring and the flat copper foil. The spring itself possesses a certain degree of elasticity, and the combination of a rotating member and a compression spring within the clamp effectively reduces damage to the flat copper foil during flexible flat cable connector testing.
