Description

Technical Field

[0001] This invention relates to the field of flexible flat cable testing technology, and more specifically, to a synchronously moving flexible flat cable conveying and testing device and its testing method. Background Technology

[0002] Flexible flat cable (FFC) allows for arbitrary selection of the number and spacing of wires, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency. It is best suited for data transmission cables between moving parts and motherboards, between PCBs, and in miniaturized electrical equipment.

[0003] After the production of the flexible flat cable is completed, the tensile performance quality needs to be tested. Traditional tensile testing equipment mostly uses hydraulic cylinder drive to pull the flexible flat cable from both ends to obtain specific numerical values, thereby determining whether the tensile performance of the flexible flat cable meets the quality indicators.

[0004] Existing flexible flat cable testing methods can achieve synchronous walking and conveying testing. However, when installing the flexible flat cable on the testing equipment, it is necessary for personnel to manually operate the equipment to clamp and fix both ends of the flexible flat cable, which prolongs the entire testing cycle. In addition, the traditional method of using two flat plates to clamp the flexible flat cable is prone to causing the flexible flat cable to fall off, affecting the normal testing process. Summary of the Invention

[0005] The purpose of this invention is to provide a synchronous walking flexible flat cable conveying and detection device and its detection method to solve the problems mentioned in the background art.

[0009] A lighting feedback system is also mounted on the base. This system is electrically connected to both the buzzer and the detection system. The lighting feedback unit includes several indicator lights. The detection system can control the number of indicator lights emitting light based on the tensile strength of the flat cable being tested. When the tensile strength of the flat cable measured by the detection system reaches the expected value, the lighting feedback system can control the buzzer to operate.

[0027] The gear is connected to the roller, the rack is movably mounted on the movable seat and connected to the top seat, and the rack also meshes with the gear.

[0028] A further technical solution of this application: The detection module includes a front seat, a middle seat, and a rear seat arranged sequentially. The middle seat is movably connected between the front seat and the rear seat. The front seat is movably mounted on the base. The rear seat is connected to the execution module. The module also includes:

[0029] A sliding seat is movably disposed within the front seat body and the two are elastically connected; the sliding seat is connected to a power element.

[0030] The feedback unit, located between the middle and front seats, is used to provide feedback to the lighting feedback system on the tensile strength of the detected flexible flat cable and to control the number of illuminated indicator lights; and

[0031] The drive unit is located between the sliding seat and the intermediate seat. When the sliding seat moves, the drive unit can control the movement of the intermediate seat.

[0032] A further technical solution of this application: the feedback unit includes a resistor bar and a conductive head;

[0033] The conductive head is mounted on the front seat, and the resistor strip is mounted on the middle seat. The conductive head is located on the moving path of the resistor strip, and both the conductive head and the resistor strip are electrically connected to the lighting feedback system.

[0034] A further technical solution of this application: the drive unit includes a drive shaft, ball bearings, and a retaining bar;

[0036] A further technical solution of this application: the lighting feedback system also includes a lamp holder, a connector, a conductive strip, a position adjustment component, and a triggering unit;

[0037] The lamp holder is mounted on the base, and several indicator lights are mounted on the lamp holder. The number of the electrical connectors is the same as the number of indicator lights. Each electrical connector corresponds to one indicator light and is electrically connected to one indicator light. The conductive strip is movably mounted on the base, and the electrical connectors are located on the moving path of the conductive strip.

[0039] A further technical solution of this application: the triggering unit includes an adjustment base and a photoresistor;

[0040] The adjustment seat is movably mounted on the machine base and slides in conjunction with the lamp holder. A cavity is formed inside the adjustment seat, and the photoresistor is disposed inside the cavity. The indicator lamp is located on the moving path of the cavity.

[0041] A detection method for a synchronously moving flexible flat cable conveying detection device includes the following steps:

[0042] Step 1: Pass the flexible flat cable to be tested through the area between the top seat and the base and lay it symmetrically on the two bases on the machine base. The hydraulic cylinder retracts, driving the moving seat to move outwards from the machine base.

[0043] Step 2: Under the frictional resistance of the base and the roller, the roller is driven to rotate. The rotation of the roller drives the gear to rotate synchronously. Under the meshing action of the gear and rack, the top seat and the intermediate clamping plate are driven to move towards the base until the intermediate clamping plate is tightly attached to the flexible flat cable. The flexible flat cable is clamped and fixed by the clamping of the intermediate clamping plate and the base. As the roller continues to rotate, the top seat continues to move towards the base, so that the protrusion is inserted into the groove.

[0044] Step 3: When the hydraulic cylinder drives the moving seat to move outwards from the machine base and straightens the flexible flat cable, the sliding seat drives the drive shaft to move to the left relative to the front seat. Under the combined action of the spiral groove and ball bearings, as well as the combined action of the slot and the clip, the middle seat and the resistance strip rotate. As the tension on the flexible flat cable gradually increases, the conductive head contacts different positions of the resistance strip, and the current through the circuit of the trigger electromagnet changes continuously. Then, according to the current, the conductive strip moves to the right a certain distance and contacts the corresponding number of terminals, so that the indicator lights can light up according to the tensile strength of the flexible flat cable. When the indicator light at the position blocked by the adjusting seat lights up, the photoresistor controls the buzzer to sound an alarm to determine whether the quality of the flexible flat cable meets the standard. Compared with the traditional method of displaying digital data on the display screen.

[0045] Compared with the prior art, the technical solution provided by the embodiments of the present invention has the following beneficial effects:

[0046] This invention utilizes the frictional resistance between the rollers and the abrasive strips. When the moving seat moves towards both sides of the machine base under the control of the hydraulic cylinder, the rollers also drive the top seat to move towards the base, thus achieving automatic clamping and fixing of the flexible flat cable. The cooperation between the protrusion and the groove improves the fixing effect of the flexible flat cable. Moreover, the clamping stability of the flexible flat cable is proportional to the number of rotations of the rollers. This eliminates the need for traditional manual fixing of flexible flat cables, shortens the inspection cycle, and also eliminates the need for traditional flat plate clamping. The clamping and fixing effect of this device is better, and the phenomenon of flexible flat cable falling off is less likely to occur. Attached Figure Description

Detailed Implementation

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention will be further described below with reference to the embodiments.

[0058] Please see Figures 1-8 In one embodiment of this application, a synchronously moving flexible flat cable conveying and detection device includes a base 1 and a buzzer 7, wherein the buzzer 7 is disposed on the base 1, and further includes:

[0059] The testing system, mounted on base 1, is used to test the tensile strength of the flexible flat cable; and

[0060] A lighting feedback system is also installed on the base 1. This system is electrically connected to the buzzer 7 and the detection system. The lighting feedback unit includes several indicator lights 9. The detection system can control the number of indicator lights 9 to illuminate based on the measured tensile strength of the flexible flat cable. When the measured tensile strength of the flexible flat cable reaches the expected value, the lighting feedback system can control the buzzer 7 to operate.

[0061] The detection system includes:

[0062] The execution module 5, consisting of two sets symmetrically arranged on the base 1, is used to fix the flexible flat cable and perform the stretching action on the flexible flat cable.

[0063] A power element, disposed between the base 1 and the actuator 5, is used to adjust the position of the actuator 5; and

[0064] The detection module 6 is located between the power element and the execution module 5 and is used to perform the measurement action of the tensile strength of the flexible flat cable.

[0065] In this embodiment, it should be specifically noted that the power element can be replaced by a linear motor, electric cylinder, or pneumatic cylinder, etc. In this embodiment, the power element is preferably a hydraulic cylinder 3, such as... Figure 1 As shown, the hydraulic cylinder 3 is connected between the execution module 5 and the base 1.

[0066] In this embodiment, the execution module 5, by way of example, includes:

[0067] A movable seat 501 is movably mounted on a base 1. At least one guide rod 2 is provided on the base 1 that passes through the movable seat 501. The guide rod 2 and the movable seat 501 are slidably engaged. A roller 502 is also movably mounted on the movable seat 501.

[0068] Base 505 is mounted on movable base 501;

[0069] Top seat 508, movably mounted on one side of base 505 and connected to roller 502; and

[0070] An enhancement unit is disposed between the top seat 508 and the base 505. The enhancement unit is connected to the roller 502. When the roller 502 is working, it can control the enhancement unit and the base 505 to move synchronously.

[0071] In practical applications, the flexible flat cable to be tested is passed through the area between the top seat 508 and the base 505 and symmetrically laid on the two bases 505 on the base 1. The hydraulic cylinder 3 retracts, causing the moving seat 501 to... Figure 1 The device moves outwards from the base 1 in the indicated direction. Under the frictional resistance of the base 1 and the roller 502, the roller 502 rotates, which in turn moves the top seat 508 towards the base 505 to clamp and fix the flexible flat cable. This eliminates the need for manual operation, shortening the installation time and testing cycle of the flexible flat cable. During this process, the greater the displacement of the moving seat 501, the more rotations the roller 502 makes, resulting in a greater clamping force between the top seat 508 and the base 505 on the flexible flat cable. At the same time, the efficiency enhancement unit further improves the clamping effect of the flexible flat cable, preventing it from falling off. When the flexible flat cable is straightened, the tensile strength of the flexible flat cable is tested by the detection module 6. The higher the tensile strength value, the more lights 9 illuminate. When the tensile strength of the flexible flat cable reaches the expected value, the light feedback system controls the buzzer 7 to alarm and alert the operator. Compared with traditional testing equipment, manual data comparison is no longer required.

[0072] Please see Figures 1-4 As another preferred embodiment of this application, a frosting strip 4 is provided on one side of the movable seat 501 on the base 1, and the roller 502 slides in cooperation with the frosting strip 4.

[0073] In one specific embodiment of this invention, the enhancement unit includes:

[0074] An intermediate clamping plate 507 is disposed between the top seat 508 and the base 505, and the intermediate clamping plate 507 and the base 505 are connected by a number of elastic elements.

[0075] A limiting plate 509 is movably mounted on a top seat 508 and the two are elastically connected. The limiting plate 509 is connected to an intermediate clamping plate 507.

[0076] There are several grooves 506, and all of the grooves 506 are provided on the base 505.

[0077] The number of bosses 510 is the same as the number of grooves 506 and they are disposed on the top seat 508. The intermediate clamping plate 507 has through holes through which the bosses 510 pass, and the grooves 506 are located on the moving path of the bosses 510; and

[0078] The transmission component is located between the roller 502 and the top seat 508. When the roller 502 moves, the transmission component controls the top seat 508 to move synchronously.

[0079] It should be noted that the elastic element can be a spring sheet, an elastic steel plate, or an elastic rubber structure. In this embodiment, the elastic element is preferably a spring 511, which is connected between the intermediate clamping plate 507 and the base 505. Figure 2 As shown.

[0080] It should be specifically noted that the transmission component includes a gear 503 and a rack 504;

[0081] The gear 503 is connected to the roller 502, the rack 504 is movably mounted on the movable seat 501 and connected to the top seat 508, and the rack 504 also meshes with the gear 503.

[0082] Of course, the transmission component in this embodiment is not limited to the mechanical replacement method described above. It can also be replaced by a rotation counter in conjunction with a linear motor or an electric cylinder. For example, the rotation counter measures the number of rotations of the roller 502, and the linear motor is directly driven to control the top seat 508 to move toward the base 505 based on the number of rotations of the roller 502. This will not be described in detail here.

[0083] When the movable seat 501 moves, the roller 502 rotates, driving the gear 503 to rotate synchronously. Under the meshing action of the gear 503 and the rack 504, the top seat 508 and the intermediate clamping plate 507 move towards the base 505 until the intermediate clamping plate 507 is tightly attached to the flexible flat cable. The flexible flat cable is clamped and fixed by the clamping of the intermediate clamping plate 507 and the base 505. As the roller 502 continues to rotate, the top seat 508 continues to move towards the base 505, so that the protrusion 510 is inserted into the groove 506, thereby improving the fixing effect of the flexible flat cable. Compared with the traditional flat plate clamping method, it avoids the phenomenon of the flexible flat cable falling off during tensile performance testing.

[0084] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6In another preferred embodiment of this application, the detection module 6 includes a front seat 601, a middle seat 603, and a rear seat 602 arranged sequentially. The middle seat 603 is movably connected between the front seat 601 and the rear seat 602. The front seat 601 is movably mounted on the base 1, and the rear seat 602 is connected to the execution module 5. The module also includes:

[0085] A sliding seat 605 is movably disposed within the front seat body 601 and the two are elastically connected. The sliding seat 605 is connected to the power element.

[0086] A feedback unit, located between the intermediate base 603 and the front base 601, is used to provide feedback to the lighting feedback system on the tensile strength of the detected flexible flat cable and to control the number of illuminating indicator lights 9; and

[0087] A drive unit is disposed between the sliding seat 605 and the intermediate seat 603. When the sliding seat 605 moves, the drive unit can control the movement of the intermediate seat 603.

[0088] In one specific embodiment, the feedback unit includes a resistor bar 604 and a conductive head 611;

[0089] The conductive head 611 is disposed on the front seat 601, the resistor strip 604 is sleeved on the middle seat 603, and the conductive head 611 is located on the moving path of the resistor strip 604. Both the conductive head 611 and the resistor strip 604 are electrically connected to the lighting feedback system.

[0090] In another specific embodiment, the drive unit includes a drive shaft 606, a ball bearing 608, and a retaining bar 609;

[0091] The drive shaft 606 is movably mounted on the sliding seat 605, the ball bearing 608 is slidably embedded on the drive shaft 606, the front seat 601 is provided with a spiral groove 607 that slidably engages with the ball bearing 608, the retaining bar 609 is mounted on the drive shaft 606, and the intermediate seat 603 is provided with a retaining groove 610 that slidably engages with the retaining bar 609.

[0092] Of course, the driving unit in this embodiment is not limited to the mechanical replacement method described above. As long as it can drive the intermediate seat 603 to rotate, it can also be replaced by an infrared ranging sensor in conjunction with a stepper motor or a servo motor. For example, the moving distance of the sliding seat 605 can be measured by the infrared ranging sensor, and the stepper motor can be controlled to rotate the corresponding angle according to the moving distance of the sliding seat 605. No specific limitation is made here.

[0093] When the hydraulic cylinder 3 drives the movable seat 501 to move outward toward the machine base 1 and straightens the flexible cable, the sliding seat 605 drives the drive shaft 606 relative to the front seat body 601 as follows: Figure 5The direction shown is shifted to the left. Under the cooperation of the spiral groove 607 and the ball 608, and the cooperation of the slot 610 and the strip 609, the intermediate seat 603 and the resistor strip 604 are driven to rotate. As the tension on the flexible flat cable gradually increases, the conductive head 611 contacts the resistor strip 604 at different positions, which causes the number of lights 9 in the light feedback system to be different. When the number of lights 9 reaches the expected value, it means that the tensile performance of the flexible flat cable has reached the quality index. When the light is off (the flexible flat cable is completely torn) or the number of lights 9 does not reach the expected value, it means that the tensile performance of the flexible flat cable is not up to standard.

[0094] Please see Figure 1 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As another preferred embodiment of this application, the lighting feedback system further includes a lamp holder 8, a power connector 10, a conductive strip 13, a position adjustment component, and a triggering unit;

[0095] The lamp holder 8 is mounted on the base 1, and a number of display lamps 9 are mounted on the lamp holder 8. The number of the electrical connectors 10 is the same as that of the display lamps 9. Each electrical connector 10 corresponds to and is electrically connected to one display lamp 9. The conductive strip 13 is movably mounted on the base 1, and the electrical connectors 10 are located on the moving path of the conductive strip 13.

[0096] The position adjustment component is disposed between the conductive strip 13 and the base 1 and can adjust the position of the conductive strip 13. The position adjustment component is also electrically connected to the feedback unit. The trigger unit is movably disposed on the base 1 and can control the opening and closing of the buzzer 7.

[0097] In one specific embodiment, the triggering unit includes an adjustment base 11 and a photoresistor 12;

[0098] The adjustment seat 11 is movably mounted on the base 1 and slides with the lamp holder 8. A cavity is formed inside the adjustment seat 11, the photoresistor 12 is disposed in the cavity, and the indicator lamp 9 is located on the moving path of the cavity.

[0099] In another specific embodiment, the position adjustment component includes a set of electromagnets 14 that are energized and repulsive, a drive base 15, and a spring 16.

[0100] The drive base 15 is movably disposed within the base 1 and connected to the conductive strip 13. Both the drive base 15 and the base 1 are equipped with electromagnets 14. The spring 16 is disposed within the base 1 and its free end is connected to the drive base 15.

[0101] Of course, the position adjustment component in this embodiment is not limited to the structure of the electromagnet 14 described above. It can also be replaced by a linear motor, electric cylinder, or hydraulic cylinder 3 for direct drive. These will not be listed here.

[0102] In practical applications, when the conductive head 611 contacts the resistor strip 604 at different positions, the magnitude of the current passing through the circuit where the electromagnet 14 is located changes continuously, and thus the conductive strip 13 is driven as follows by the current. Figure 1 The device moves a certain distance to the right in the indicated direction and contacts the corresponding number of connectors 10, so that the indicator lights 9 can light up in the corresponding number according to the tensile strength of the flexible flat cable. When the indicator lights 9 in the position blocked by the adjusting seat 11 light up, the photoresistor 12 controls the buzzer 7 to sound an alarm to indicate whether the quality of the flexible flat cable meets the standard. Compared with the traditional method of displaying digital data through a display screen, this device has a simpler structure and can more intuitively provide feedback on the measurement results to the staff and automatically judge the measurement results, thus reducing the labor intensity of the staff.

[0103] It should be noted that all elastic connections involved in this application can be replaced by spring sheets, elastic steel plates or elastic rubber structures. No specific details are given here, and the best choice can be made according to the actual situation.

[0104] A detection method for a synchronously moving flexible flat cable conveying detection device includes the following steps:

[0105] The flexible flat cable to be tested is passed through the area between the top seat 508 and the base 505 and symmetrically laid on the two bases 505 on the machine base 1. The hydraulic cylinder 3 retracts, causing the moving seat 501 to... Figure 1 The roller 502 moves outward in the direction shown. Under the frictional resistance between the base 1 and the roller 502, the roller 502 rotates. The rotation of the roller 502 drives the gear 503 to rotate synchronously. Under the meshing action of the gear 503 and the rack 504, the top seat 508 and the intermediate clamping plate 507 move towards the base 505 until the intermediate clamping plate 507 is tightly attached to the flexible flat cable. The flexible flat cable is clamped and fixed by the clamping of the intermediate clamping plate 507 and the base 505. As the roller 502 continues to rotate, the top seat 508 moves towards the base 505. The continuous movement towards the base 505 causes the protrusion 510 to insert into the groove 506, thereby improving the fixing effect of the flexible flat cable. Compared with the traditional flat clamping method, this avoids the phenomenon of the flexible flat cable falling off during tensile performance testing. It eliminates the need for manual operation by staff, shortening the installation time and testing cycle of the flexible flat cable and preventing its detachment. When the hydraulic cylinder 3 drives the moving seat 501 to move outward towards the machine base 1 and straightens the flexible flat cable, the sliding seat 605 drives the drive shaft 606 relative to the front seat 601 as... Figure 5Moving to the left in the indicated direction, the interaction between the spiral groove 607 and the ball bearing 608, as well as the interaction between the slot 610 and the retaining bar 609, causes the intermediate seat 603 and the resistance bar 604 to rotate. As the pulling force on the flexible cable gradually increases, the conductive head 611 contacts the resistance bar 604 at different positions, triggering the electromagnet 14 to continuously change the magnitude of the current passing through the circuit. This, in turn, drives the conductive bar 13 as follows... Figure 1 The device moves a certain distance to the right in the indicated direction and contacts the corresponding number of connectors 10, so that the indicator lights 9 can light up in the corresponding number according to the tensile strength of the flexible flat cable. When the indicator lights 9 in the position blocked by the adjusting seat 11 light up, the photoresistor 12 controls the buzzer 7 to sound an alarm to indicate whether the quality of the flexible flat cable meets the standard. Compared with the traditional method of displaying digital data through a display screen, this device has a simpler structure and can more intuitively provide feedback on the measurement results to the staff and automatically judge the measurement results, thus reducing the labor intensity of the staff.

[0106] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.

9. A detection method for a synchronously moving flexible flat cable conveying detection device as described in any one of claims 1-8, characterized in that, Includes the following steps: Step 1: Pass the flexible flat cable to be tested through the area between the top seat and the base and lay it symmetrically on the two bases on the machine base. The hydraulic cylinder retracts, driving the moving seat to move outwards from the machine base. Step 2: Under the frictional resistance of the base and the roller, the roller is driven to rotate. The rotation of the roller drives the gear to rotate synchronously. Under the meshing action of the gear and rack, the top seat and the intermediate clamping plate are driven to move towards the base until the intermediate clamping plate is tightly attached to the flexible flat cable. The flexible flat cable is clamped and fixed by the clamping of the intermediate clamping plate and the base. As the roller continues to rotate, the top seat continues to move towards the base, so that the protrusion is inserted into the groove. Step 3: When the hydraulic cylinder drives the moving seat to move outwards from the machine base and straightens the flexible flat cable, the sliding seat drives the drive shaft to move to the left relative to the front seat. Under the combined action of the spiral groove and ball bearings, as well as the combined action of the slot and the clip, the middle seat and the resistance strip rotate. As the tension on the flexible flat cable gradually increases, the conductive head contacts different positions of the resistance strip, and the current through the circuit of the trigger electromagnet changes continuously. Then, according to the current, the conductive strip moves to the right a certain distance and contacts the corresponding number of terminals, so that the indicator lights can light up according to the tensile strength of the flexible flat cable. When the indicator light at the position blocked by the adjusting seat lights up, the photoresistor controls the buzzer to sound an alarm to determine whether the quality of the flexible flat cable meets the standard. Compared with the traditional method of displaying digital data on the display screen.
