Description

Technical Field

[0001] The invention relates to the technical field of FFC wire conductivity testing, in particular to testing equipment and a testing method for FFC wire processing. Background Art

[0002] FFC flexible flat cable is a kind of PET insulation material and very thin tinned flat copper wire. It is widely used in the connection between the print head and the motherboard of various printers, the signal transmission and board-to-board connection of plotters, scanners, copiers, audio, LCD appliances, fax machines, various DVD players and other products. In modern electrical equipment, it is almost everywhere. In order to ensure the quality of FFC wires, the gold fingers on the FFC wires need to be tested before the FFC wires are put on the market to check their conductive properties.

[0003] Originally, the conductive testers on the market all used probes to contact the gold fingers, and then judged the conductive conditions by the lighting of the test host, and then determined whether the quality of the FFC wire was qualified. However, during the test, excessive pressure on the probe often damages the gold-plated layer of the gold finger, which in turn affects its corrosion resistance. For this reason, we have previously proposed a patent with announcement number CN212749205U, and the patent name is a conductive tester for FFC wires. This solution can prevent the probe from being over-pressed through a limiting mechanism, which not only ensures that the probe is not easy to bend and deform, but also ensures that the gold finger coating is not damaged. With the application of this technology, the defects of this solution have gradually been exposed, that is, before placing the FFC wire each time, the solution needs to lift the probe, and after the FFC wire is placed, the probe is controlled to move down to contact the gold finger at the end of the FFC for testing. Such testing efficiency is low and cannot meet the existing batch FFC wire processing and testing needs. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 8 As shown, the present invention includes the following embodiments:

[0032] Embodiment 1: A testing device for FFC wire processing, comprising a base 1 and a support leg 11 on the lower surface of the base 1; the upper surface of the base 1 is fixedly connected to a vertical plate 2; one side of the vertical plate 2 is fixedly connected to a controller 21; the vertical plate 2 is rotatably connected to an upper active roller 3 and an upper driven roller 4 at the same horizontal height on a side away from the controller 21; the upper active roller 3 is driven by an upper motor 31; the outer walls of the upper active roller 3 and the upper driven roller 4 are transmission-connected to an upper conveyor belt 5; the vertical plate 2 is rotatably connected to an upper conveyor belt 5 on a side away from the controller 21 A lower active roller 6 and a lower driven roller 7; the lower active roller 6 is driven by a lower motor 61; the outer walls of the lower active roller 6 and the lower driven roller 7 are connected to the lower conveyor belt 8 by transmission; the lower conveyor belt 8 is located below the upper conveyor belt 5; the length of the upper conveyor belt 5 is less than that of the lower conveyor belt 8; the upper conveyor belt 5 is located in the middle of the lower conveyor belt 8 in the front-to-back direction; a probe 51 is provided on the outer wall of the upper conveyor belt 5; a storage groove 81 is provided on the outer wall of the lower conveyor belt 8; the storage groove 81 corresponds to the probe 51 on the upper conveyor belt 5 under the transmission of the lower conveyor belt 8.

[0033] In this embodiment, the upper conveyor belt 5 and the lower conveyor belt 8 are both made of elastic material, such as rubber; the angle between the side of the vertical plate 2 facing away from the upper conveyor belt 5 and the upper surface of the base 1 is less than 90 degrees.

[0034] After the staff completes the processing of the FFC wire, the staff transfers the FFC wire to the front side of the test equipment. Since the length of the lower conveyor belt 8 is greater than that of the upper conveyor belt 5, and the upper conveyor belt 5 is located in the middle of the lower conveyor belt 8 in the front-to-back direction, the lower conveyor belt 8 protrudes from the upper conveyor belt 5 in the front-to-back direction. Then the staff sequentially puts the processed FFC wire into the storage slot 81 of the lower conveyor belt 8. The storage slot 81 on the upper surface of the lower conveyor belt 8 opens upward, so after the FFC wire is placed in the storage slot 81, the FFC wire in the storage slot 81 with the opening facing upward will not move out. The storage slot 81 where the FFC wire is placed will move backward with the transmission of the lower conveyor belt 8. The transmission directions of the upper conveyor belt 5 and the lower conveyor belt 8 are opposite, and the speeds are consistent.

[0035] In this way, while the lower motor 61 drives the lower conveyor belt 8 to transmit through the lower active roller 6, the upper motor 31 drives the upper conveyor belt 5 to transmit through the upper active roller 3. The probe 51 on the outer wall of the upper conveyor belt 5 and the storage slot 81 on the outer wall of the lower conveyor belt 8 are aligned after approaching. In this way, when the storage slot 81 drives the FFC wire to move to the lower side of the corresponding upper conveyor belt 5, the probe 51 on the outer wall of the upper conveyor belt 5 will enter the storage slot 81 and press the gold finger at one end of the FFC wire in the storage slot 81. After the gold finger is pressed, the prompt light 53 lights up, indicating that the gold finger at one end of the FFC wire is in good conductivity and meets the product quality requirements. On the contrary, when the corresponding prompt light 53 does not light up, it indicates that the product quality of the corresponding FFC wire is unqualified. Since the upper conveyor belt 5 has a certain length, the probe 51 can be kept in contact with the corresponding gold finger at the end of the FFC wire to be tested in the front and rear directions, thereby extending the power-on test time and improving the test accuracy.

[0036] The staff sequentially places the FFC wire into the storage slot 81 exposed at the front end of the lower conveyor belt 8. The vibration generated during the transmission of the lower conveyor belt 8 will be transmitted to the FFC wire in the storage slot 81. Since the angle between the side of the vertical plate 2 away from the upper conveyor belt 5 and the upper edge of the base 1 is less than 90 degrees, the end of the storage slot 81 close to the vertical plate 2 is lower than the end away from the vertical plate 2 in the vertical direction, so that the FFC wire in the storage slot 81 is affected by the vibration before contacting the probe 51 and moves toward the vertical plate 2, thereby automatically calibrating the position of the FFC wire in the storage slot 81, so that the gold finger at one end of the FFC wire is aligned with the probe 51 on the outer wall of the upper conveyor belt 5, so that the test accuracy of the FFC wire is further improved;

[0037] As the storage slot 81 on the lower conveyor belt 8 continuously places FFC wires, the testing equipment will use the transmission of the upper conveyor belt 5 and the lower conveyor belt 8 to perform continuous FFC wire testing, making the test more continuous and improving the testing efficiency of the existing processed FFC wires; as the lower conveyor belt 8 is driven, the lower conveyor belt 8 will drive the FFC wires in the storage slot 81 to move backward from the bottom of the upper conveyor belt 5 and move out, and as the lower driven roller 7 rotates, the storage slot 81 with the outer wall opening facing upward on the lower conveyor belt 8 will flip downward, and the staff will catch the FFC wires that have been moved out with the storage slot 81 flipped and the opening facing downward, and finally classify the quality.

[0038] Embodiment 2: The lower motor 61 is fixedly connected to the side of the vertical plate 2 away from the lower conveyor belt 8, and the output shaft of the lower motor 61 is connected to one end of the lower active roller 6; the upper motor 31 is fixedly connected to the side of the vertical plate 2 away from the upper conveyor belt 5, and the output shaft of the upper motor 31 is fixedly connected to the main square rod 32; the center of the upper active roller 3 is connected to the main square rod 32 through the main square hole 33; the vertical plate 2 is rotated toward the side of the upper conveyor belt 5 and connected to the slave square rod 22; the center of the upper driven roller 4 is connected to the slave square rod 2 through the slave square hole 41 2 connection; the upper active roller 3, the upper driven roller 4 and the upper conveyor belt 5 are all two; the probes 51 on the outer walls of the two upper conveyor belts 5 are correspondingly arranged; the same storage slot 81 can simultaneously enter the two probes 51; the upper conveyor belt 5 close to the vertical plate 2 is fixedly connected to the power supply 52, and the upper conveyor belt 5 away from the vertical plate 2 is fixedly connected to the warning light 53; the warning light 53 is connected in series with the corresponding power supply 52 through the wiring harness 54; the power supply 52, the wiring harness 54, the warning light 53 and the corresponding two probes 51 are electrically connected in series.

[0039] In this embodiment, the upper active roller 3 close to the vertical plate 2 is fixedly connected to the main square rod 32, and the upper active roller 3 away from the vertical plate 2 is slidably connected to the main square rod 32 through the main square hole 33; the upper driven roller 4 close to the vertical plate 2 is fixedly connected to the slave square rod 22, and the upper driven roller 4 away from the vertical plate 2 is slidably connected to the slave square rod 22 through the slave square hole 41.

[0040] In this embodiment, the thickness of the upper active roller 3 and the upper driven roller 4 away from the vertical plate 2 is greater than that of the upper conveyor belt 5; a main threaded hole 34 is provided through the outer wall of the upper active roller 3 away from the vertical plate 2 and the corresponding main square hole 33; the main threaded hole 34 is threadedly connected to the main bolt 35; the outer wall of the upper driven roller 4 away from the vertical plate 2 and the corresponding slave square hole 41 are threadedly provided with a slave threaded hole 42; the slave threaded hole 42 is threadedly connected to the slave bolt 43.

[0041] Before the test, the staff will adjust the distance between the two corresponding joints according to the length of the two gold fingers at the end of the FFC wire. The length of the FFC wires of the same batch is consistent, while the length of the FFC wires of different batches may be different. In order to improve the test range of the test equipment and meet the test requirements of FFC wires of different lengths, the staff will turn the main bolt 35 and the slave bolt 43. After the main bolt 35 is turned, it will be out of contact with the outer wall of the main square rod 32, so that the main square hole 33 in the center of the upper active roller 3 is unlocked from the outer wall of the main square rod 32;

[0042] Similarly, in the process of tightening the slave bolt 43, the slave bolt 43 rotates and disengages from the contact with the outer wall of the slave square rod 22, so that the slave square hole 41 in the center of the upper driven roller 4 is unlocked from the outer wall of the slave square rod 22. After the upper active roller 3 is unlocked from the main square rod 32, the upper active roller 3 can slide along the outer wall of the main square rod 32. After the upper driven roller 4 is unlocked from the slave square rod 22, the upper driven roller 4 can slide along the outer wall of the slave square rod 22, so that the distance between the two upper conveyor belts 5 is changed. When the distance between the two upper conveyor belts 5 is changed, the distance between the corresponding probes 51 on the two upper conveyor belts 5 is also changed, until the spacing between the corresponding probes 51 on the two upper conveyor belts 5 is equal to or smaller than that between the upper conveyor belts 5 and the main square rod 32. When the distance between the two gold fingers at the end of the FFC wire is adapted, the main bolt 35 and the slave bolt 43 are screwed in the opposite direction. The main bolt 35 moves along the main threaded hole 34 and contacts the outer wall of the main square rod 32, so that the upper active roller 3 away from the vertical plate 2 is locked with the main square rod 32. The slave bolt 43 moves along the slave threaded hole 42 and contacts the outer wall of the slave square rod 22, so that the upper driven roller 4 away from the vertical plate 2 is locked with the slave square rod 22. In this way, the distance between the two upper conveyor belts 5 is locked, and the adjustment of the distance between the corresponding probes 51 on the two upper conveyor belts 5 is completed, so that the test equipment can meet the test requirements of FFC wires of different lengths, and the test range is wider;

[0043] After completing the spacing adjustment of the corresponding probes 51 on the two upper conveyor belts 5, place the FFC wire in the storage slot 81 close to one end of the vertical plate 2. With the transmission of the lower conveyor belt 8, the two upper conveyor belts 5 will drive the corresponding probes 51 to enter the same storage slot 81. The probes 51 on the outer walls of the two upper conveyor belts 5 will contact the gold fingers corresponding to the ends of the FFC wires in the storage slot 81. The FFC wire, the two probes 51, the power supply 52, the wiring harness 54 and the prompt light 53 are connected in series. If the quality of the FFC wire is fine, the prompt light 53 will light up. If there is a problem with the quality of one of the gold fingers at the end of the FFC wire or the middle section of the FFC wire, the prompt light 53 will not light up. In this way, the two gold fingers at the end of the FFC wire are detected simultaneously to improve the testing efficiency of the FFC wire.

[0044] Embodiment 3: The unloading strip 9 is movably connected in the storage trough 81; the unloading strip 9 is connected to the bottom of the storage trough 81 by an elastic rope 91; the unloading strip 9 is fixedly connected to a push block 92 on one side close to the bottom of the storage trough 81; the push block 92 passes through the bottom of the storage trough 81 and extends to the inner side of the lower conveyor belt 8; the push block 92 is slidably connected to the lower conveyor belt 8; the push block 92 can drive the unloading strip 9 to move in the storage trough 81 under the squeezing of the lower active roller 6 and the lower driven roller 7.

[0045] In this embodiment, a pressure-bearing seat 82 is provided on the inner side of the lower conveyor belt 8; the front and rear ends of the pressure-bearing seat 82 are arc-shaped; the pressure-bearing seat 82 is made of elastic material; the length of the pressure-bearing seat 82 in the front-to-back direction is consistent with that of the upper conveyor belt 5; the pressure-bearing seat 82 is located directly below the upper conveyor belt 5; the pressure-bearing seat 82 can squeeze the push block 92.

[0046] When the lower motor 61 drives the lower conveyor belt 8 to transmit, the lower conveyor belt 8 will drive the storage groove 81 on the outer wall to transmit, and the storage groove 81 will drive the unloading strip 9 and the push block 92 on the inner side to transmit along with the transmission of the lower conveyor belt 8. When the push block 92 passes through the lower active roller 6, the push block 92 will be squeezed by the outer wall of the lower active roller 6 and drive the unloading strip 9 to move in the storage groove 81. The unloading strip 9 will move away from the bottom of the corresponding storage groove 81 and pull the corresponding elastic rope 91. The storage groove 81 will be turned upward with the transmission of the lower conveyor belt 8 when the opening is facing downward. The push block 92 will be separated from the outer wall of the lower active roller 6 along with the transmission of the lower conveyor belt 8, and the elastic rope 91 will pull the unloading strip 9 close to the bottom of the storage groove 81, so that the storage groove 81 is recessed again, and then the staff will put the FFC wire into the surface of the discharge bar 9 in the storage slot 81. The FFC wire moves backward with the transmission of the lower conveyor belt 8, and the lower conveyor belt 8 will drive the storage slot 81 containing the FFC wire to move to just below the upper conveyor belt 5. The push block 92 is squeezed by the elastic pressure-bearing seat 82 and drives the corresponding discharge bar 9 to move in the storage slot 81. The discharge bar 9 will drive the FFC wire away from the bottom of the storage slot 81 in the storage slot 81 and pull the corresponding elastic rope 91. In this way, during the test of discharge bars 9 with different thicknesses, the contact effect between the gold finger at the end of the FFC wire and the probe 51 can be guaranteed, ensuring the smooth progress of the test, so that the test range of the test equipment is further improved;

[0047] The push block 92 continues to move backward with the transmission of the lower conveyor belt 8, and the push block 92 will be out of contact with the pressure seat 82. The unloading bar 9 will approach the bottom of the corresponding storage groove 81 under the pull of the elastic rope 91. As the push block 92 contacts the outer wall of the lower driven roller 7, the push block 92 is squeezed by the outer wall of the lower driven roller 7 and drives the unloading bar 9 to move along the storage groove 81. The opening of the storage groove 81 changes with the rotation of the lower driven roller 7. During the downward flipping of the opening of the storage groove 81, the unloading bar 9 pushes the FFC wire in the storage groove 81, thereby realizing the rapid unloading of the FFC wire after the test is completed.

[0050] S2: Control the lower motor 61 and the upper motor 31 to rotate, the lower conveyor belt 8 and the upper conveyor belt 5 to drive, and put the FFC wires into the storage groove 81 of the lower conveyor belt 8 with the opening facing upward in sequence. The FFC wires move close to the vertical plate 2 in the inclined storage groove 81. The lower conveyor belt 8 will drive the FFC wires to move backward and enter between the upper conveyor belt 5 and the pressure seat 82. The upper conveyor belt 5 drives the probe 51 of the outer wall to enter the storage groove 81. The push block 92 is squeezed by the pressure seat 82 to drive the unloading bar 9 to move in the storage groove 81. The unloading bar 9 squeezes the FFC wires close to the probe 51, and the lighting of the prompt light 53 is observed;

[0051] S3: The lower conveyor belt 8 will drive the tested FFC wire to move backward along with the movement of the storage trough 81, and the push block 92 will be squeezed by the outer wall of the lower driven roller 7 to drive the unloading bar 9 to push the FFC wire in the storage trough 81; the FFC wire will be pushed out after the opening of the storage trough 81 is flipped, and the testing process of the processed FFC wire will be completed.
