Description

Technical Field

[0001] The present application relates to the technical field of flying probe testing, and specifically discloses an auxiliary device for flying probe machine testing. Background Art

[0002] Flying probe testing is the latest solution to some major problems in electrical testing. It replaces the bed of nails with probes and uses multiple motor-driven, fast-moving electrical probes to contact the pins of the device and perform electrical measurements.

[0003] The probe surface is prone to dirt after multiple contacts with the circuit board. If the probe is not cleaned regularly, the test results will be affected. Conventional probe cleaning requires the probe to be removed, which increases the downtime of the test equipment. In addition, the vibration test and flying probe test of the circuit board are performed separately, which makes the circuit board test process long and the circuit board test efficiency low.

[0004] To solve the above problems, a Chinese patent with announcement number CN219902726U discloses a circuit board testing device, including a machine, a first drive shaft, a second drive shaft, a third drive shaft, multiple probes, a detection frame and a cleaning tank. The detection frame is installed on the machine through a vibrator, and the first drive shaft and the cleaning tank are both installed on the machine. After the probe has worked for a long time, the probe runs into the cleaning tank, and the cleaning tank cleans the probe without stopping the machine. This not only shortens the testing process of the circuit board, but also improves the testing efficiency of the circuit board.

[0005] The above-mentioned device has the following problems during actual use: during the long-term use of the probe, certain defects appear on the surface of the probe, which reduces the flatness and smoothness of the probe. The device only uses a cleaning tank to clean the probe, that is, it can only clean the impurities on the surface of the probe, and cannot effectively polish the defects on the surface of the probe, resulting in a continuous decrease in the flatness and smoothness of the probe surface, which in turn causes the probe to have poor detection effect and low detection efficiency, which is not conducive to the normal operation of the probe. Summary of the invention

[0006] The invention provides an auxiliary device for flying probe machine testing, so as to solve the problem that the existing testing equipment cannot grind the probe surface.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an auxiliary device for flying probe machine testing, including a base, and also including an auxiliary mechanism arranged on the base; the auxiliary mechanism includes a detection component and an auxiliary component; the detection component includes a detection frame and a detection part arranged on the detection frame; the detection frame is fixedly connected to the base; the auxiliary component includes a cleaning cylinder and an auxiliary part arranged in the cleaning cylinder; the cleaning cylinder is fixedly connected to the base; the auxiliary part includes an annular hollow block, a movable block, a rotating shaft, a polishing block, a power unit for driving the annular hollow block to perform circumferential motion, and a driving unit for driving the rotating shaft to rotate; the movable block is fixedly connected to the annular hollow block; the rotating shaft is rotatably connected to the movable block; the polishing block is fixedly connected to the rotating shaft.

[0008] The principles and advantages of this solution are:

[0009] The probe is inserted into the cleaning cylinder so that the probe is attached to the polishing block. During the rotation of the polishing block, the polishing block can polish the probe to remove impurities and flaws on the probe surface, thereby enhancing the glossiness and flatness of the probe surface, improving the quality of the probe surface, and making the probe more aesthetic. That is, the use effect of the probe is enhanced and the working efficiency of the probe is improved.

[0010] Furthermore, since the polishing block can also perform circumferential motion, the working range of the polishing block is expanded, so that the polishing block can polish the probe more fully and comprehensively, further improving the glossiness and flatness of the probe surface.

[0011] Through the above movement, the polishing block polishes the probe surface and removes impurities on the probe surface, reducing the amount of impurities adhering to the polishing block, thereby ensuring that the probe can be used efficiently for a long time.

[0012] Furthermore, it also includes a grinding part; the grinding part includes a cam, a slider, a grinding block, and a spring; the cam is fixedly connected to the rotating shaft; the slider is vertically slidably connected to the movable block, and the cam and the slider are against each other; the grinding block is fixedly connected to the slider; and the two ends of the spring are respectively connected to the movable block and the slider.

[0013] After the probe is polished by the polishing block, the vertical reciprocating motion of the grinding block enables the grinding block to perform secondary grinding on the probe to achieve fine processing, thereby ensuring that the probe is polished more completely and fully, further improving the gloss and flatness of the probe, and comprehensively enhancing the use effect of the probe.

[0014] Furthermore, since the grinding block can also perform circumferential motion, the grinding block can grind the probe in the axial direction and the vertical direction at the same time, thereby expanding the grinding range of the grinding block and making the probe be polished more comprehensively and thoroughly.

[0015] In summary, the rough processing of the probe by the polishing block can improve the glossiness and flatness of the probe surface, and reduce the number of impurities adhering to the probe surface; and the fine processing of the probe by the grinding block can further enhance the processing effect of the probe, improve the working efficiency of the probe, and extend the service life of the probe.

[0016] Furthermore, it also includes a cleaning part; the cleaning part includes a water tank, a piston cylinder, a piston block, a water inlet pipe, and a hose; the water tank and the piston cylinder are both fixedly connected to the annular hollow block; the piston block is slidably connected to the piston cylinder, and the piston block is fixedly connected to the sliding block; the two ends of the water inlet pipe are respectively connected to the water tank and the piston cylinder; a water outlet groove is opened on the grinding block, and the two ends of the hose are respectively connected to the water outlet pipe and the piston cylinder.

[0017] Under the action of the piston cylinder, water is sprayed out through the water outlet. The water has a certain force, and the water can wash away the impurities adhering to the probe surface, further reducing the number of impurities adhering to the probe, thereby improving the neatness and cleanliness of the probe surface and avoiding secondary pollution. At the same time, after the water is sprayed out from the water outlet, it can reduce the friction heat generated by the grinding block and the probe surface, play a cooling role, and ensure that the grinding block and the probe will not be deformed and damaged due to excessive heat; and the water can form a layer of liquid film on the probe surface, which plays a lubricating role, reducing the friction resistance and the wear degree of the grinding block during the grinding process, and improving the grinding efficiency and quality.

[0018] Furthermore, the water outlet trough is a through hole; it also includes a linkage part; the linkage part includes a first screw, a first guide rod, a first rack, a first gear, a first nut seat, and a rubber tube; the first screw is rotatably connected to the slider; the first guide rod is fixed to the slider; the first screw and the first guide rod both extend into the through hole; the first rack is fixed to the piston cylinder; the first gear is fixed to the first screw, and the first gear is meshed with the first rack; the first nut seat is threadedly connected to the first screw, and the first nut seat is slidably connected to the first guide rod, the first nut seat is located in the through hole, and the first nut seat can reciprocate along the length direction of the through hole; the rubber tube is fixed to the inner wall of the through hole, and the rubber tube is located on the movement trajectory of the first nut seat.

[0019] The rubber tube will continuously deform under the action of the first nut seat. During the deformation of the rubber tube, the diameter of the rubber tube will be squeezed and reduced, thereby increasing the pressure inside the rubber tube, that is, the water sprayed out of the rubber tube will increase the force of the water spraying after the rubber tube is deformed. The deformation of the rubber tube can adjust the force of the water spraying, which ensures that the water can more efficiently flush impurities on the one hand, and the water can cool the grinding block and the probe more comprehensively on the other hand, which comprehensively enhances the effect of the water spraying.

[0020] Furthermore, it also includes a linkage unit symmetrically arranged on both sides of the through hole along the length direction of the through hole; the linkage unit includes a chamber opened in the grinding block, and a plurality of linkage parts are equidistantly arranged along the length direction of the chamber; a connecting groove is opened between the chamber and the through hole, and the first nut seat is in contact with the connecting groove; the linkage part includes an atomizing nozzle and a side hole opened on the chamber; the atomizing nozzle is fixedly connected to the side hole.

[0021] After the first nut seat and the connecting groove are misaligned, water can flow into the chamber, and finally flow out through the atomizing nozzle to act on the probe. Through the above movement, the water acting on the probe is in two forms: liquid and atomized liquid. When the atomized liquid acts on the probe, the contact area between the atomized liquid and the grinding block and the probe is more sufficient, and the heat is absorbed more rapidly, thereby achieving a better cooling effect on the grinding block and the probe. In addition, when the atomized liquid is discharged, the atomized liquid can better reduce the dust generated by the grinding block during grinding, so that the dust will not spread out, ensuring that the dust generated by the grinding block during grinding will not pollute the environment or cause harm to the human body.

[0022] Furthermore, it also includes a cleaning part; the cleaning part includes a guide block, a rotating shaft, a belt, a second gear, a second rack, a cleaning block, and a plurality of brush blocks; the guide block is fixedly connected to the slider; the rotating shaft is rotatably connected to the slider; the two ends of the belt are respectively mounted on the rotating shaft and the first screw; the second gear is fixedly connected to the rotating shaft; the second rack is slidably connected to the guide block; the second gear is meshed with the second rack; the cleaning block is fixedly connected to the second rack; and a plurality of brush blocks are fixedly connected to the cleaning block.

[0023] Through the horizontal and vertical movement of the bristle block, the bristle block can clean the position where the polishing block and the grinding block have acted, so that the impurities remaining on the probe are cleaned and finally fall to the bottom of the cleaning cylinder, which further improves the glossiness of the probe and enhances the use effect of the probe. In addition, because the bristle block can dry the position where water has acted, the time that water stays on the probe is shortened, ensuring that the probe can be dried quickly, so that the probe can efficiently enter the working state and improve the detection efficiency.

[0024] Furthermore, it also includes a booster unit symmetrically arranged on both sides of the cleaning block along the width direction of the cleaning block; the booster unit includes a plurality of booster parts; the booster parts include a wedge block and a rubber head; the wedge block is fixedly connected to the cleaning block; the rubber head is connected to the chamber, and the rubber head is located on the movement trajectory of the wedge block.

[0025] The wedge acts on the rubber head, so that the rubber head can be continuously deformed. During the deformation of the rubber head, the flowing water in the chamber can be pressurized, so that the water flows faster, and after being sprayed out by the atomizing nozzle, the force is stronger and the range is wider, and the cooling effect and dust reduction effect are more significant.

[0026] Furthermore, a plurality of beating blocks are fixedly connected to the polishing block; and the bristle block is located on the movement track of the beating block.

[0027] The beating block beats the bristle block, causing the bristle block to shake, thereby reducing the amount of impurities adhering to the bristle block, causing the impurities to eventually fall to the bottom of the cleaning cylinder, thereby improving the cleaning effect and efficiency of the bristle block. It can also deform the bristle block, increasing the contact area between the bristle block and the probe, allowing the bristle block to clean the probe more efficiently and fully, and comprehensively enhancing the cleaning effect of the bristle block.

[0028] Furthermore, the annular hollow block is the first annular rack; an annular groove is opened on the bottom of the inner wall of the cleaning cylinder, and the first annular rack is slidably connected to the annular groove; the power unit includes a power shaft, a third gear, and a power member for driving the power shaft to rotate; the power shaft is rotatably connected to the cleaning cylinder; the third gear is fixed to the power shaft, and the third gear is meshed with the first annular rack.

[0029] The power shaft is driven to rotate by the power member, and the third gear rotates synchronously. During the rotation of the third gear, the first annular rack is engaged with the third gear, so that the first annular rack rotates. During the rotation of the first annular rack, the movable block performs circumferential motion synchronously.

[0030] Furthermore, the driving unit includes a second annular rack and a fourth gear; the second annular rack is fixedly connected to the cleaning cylinder; the fourth gear is fixedly connected to the rotating shaft, and the fourth gear is meshed with the second annular rack.

[0031] When the rotating shaft moves in a circumferential direction with the movable block, the fourth gear moves synchronously. When the fourth gear moves, the fourth gear meshes with the second annular rack, so the fourth gear rotates. When the fourth gear rotates, the rotating shaft rotates synchronously; therefore, the rotating shaft can rotate while the rotating shaft moves in a circumferential direction.

[0052] Specific implementation process:

[0053] The circuit board to be tested is placed in the placement groove 2, and the probe 11 can test the position to be tested on the circuit board under the joint action of the first cylinder 4, the second cylinder 10 and the servo motor 6. After the probe 11 is used for a period of time, the probe 11 is gradually extended into the cleaning cylinder 12 so that the probe 11 is attached to the polishing block 17. During this period, the motor 49 is started, and the power shaft 47 is driven to rotate through the output shaft of the motor 49. During the rotation of the power shaft 47, the third gear 48 rotates synchronously. During the rotation of the third gear 48, the first annular rack is engaged with the third gear 48, and the first annular rack rotates. During the rotation of the first annular rack, the movable block 15 rotates synchronously. During the circumferential movement of the rotating shaft 16 with the movable block 15, the fourth gear 51 moves synchronously. During the movement of the fourth gear 51, the fourth gear 51 is engaged with the second annular rack 50, and the fourth gear 51 rotates. During the rotation of the fourth gear 51, the rotating shaft 16 rotates synchronously; therefore, the rotating shaft 16 can also rotate while the rotating shaft 16 moves circumferentially.

[0054] During the rotation of the rotating shaft 16, the polishing block 17 rotates synchronously. During the rotation of the polishing block 17, the polishing block 17 can polish and grind the probe 11, thereby removing impurities and defects on the surface of the probe 11, thereby enhancing the glossiness and flatness of the surface of the probe 11, improving the quality of the surface of the probe 11, and making the probe 11 more aesthetically pleasing. That is, the use effect of the probe 11 is enhanced and the working efficiency of the probe 11 is improved.

[0055] Furthermore, since the polishing block 17 can also perform circumferential motion, the working range of the polishing block 17 is expanded, so that the polishing block 17 can perform more sufficient and comprehensive polishing on the probe 11, further improving the glossiness and flatness of the surface of the probe 11.

[0056] Through the above movement, while polishing the surface of the probe 11, the polishing block 17 can also remove impurities on the surface of the probe 11, reduce the amount of impurities adhering to the polishing block 17, and ensure that the probe 11 can be used efficiently for a long time.

[0057] When the probe 11 is polished by the polishing block 17, the cam 18 rotates synchronously with the rotating shaft 16. During the rotation of the cam 18, when the protrusion of the cam 18 abuts against the slider 19, the slider 19 moves vertically downward and the spring is compressed; when the protrusion of the cam 18 no longer abuts against the slider 19, the slider 19 is reset under the action of the spring and moves vertically upward. Therefore, the slider 19 can perform vertical reciprocating motion.

[0058] During the vertical reciprocating motion of the slider 19, the grinding block 20 moves synchronously. During the motion of the grinding block 20, the grinding block 20 can perform secondary grinding on the probe 11 to achieve fine processing, thereby ensuring that the probe 11 is polished more completely and fully, further improving the glossiness and flatness of the probe 11, and comprehensively enhancing the use effect of the probe 11.

[0059] Furthermore, since the grinding block 20 can also perform circumferential motion, the grinding block 20 can grind the probe 11 in the axial direction and the vertical direction at the same time, thereby expanding the grinding range of the grinding block 20 and making the probe 11 be polished more comprehensively and thoroughly.

[0060] To sum up, by rough processing of the probe 11 by the polishing block 17, the glossiness and flatness of the surface of the probe 11 are improved, and the number of impurities adhering to the surface of the probe 11 is reduced; and then the probe 11 is finely processed by the grinding block 20, thereby comprehensively enhancing the processing effect of the probe 11, improving the working efficiency of the probe 11, and extending the service life of the probe 11.

[0061] During the vertical reciprocating motion of the slider 19, the piston block 23 moves synchronously. During the motion of the piston block 23, the piston block 23 cooperates with the piston cylinder 22, so that water can flow into the through hole 25 along the hose 24, and then spray out through the through hole 25. When the water is sprayed out, the water has a certain force, and the water can wash the impurities adhering to the surface of the probe 11, further reducing the number of impurities adhering to the probe 11, thereby improving the neatness and cleanliness of the surface of the probe 11 and avoiding secondary pollution. At the same time, after the water is sprayed out from the through hole 25, it can reduce the friction heat generated on the surface of the grinding block 20 and the probe 11, play a cooling role, and ensure that the grinding block 20 and the probe 11 will not be deformed and damaged due to excessive heat; and the water can form a layer of liquid film on the surface of the probe 11, which plays a lubricating role, reducing the friction resistance and the wear degree of the grinding block 20 during the grinding process, and improving the grinding efficiency and quality.

[0062] During the vertical reciprocating motion of the slider 19, the first guide rod 27 and the first screw rod 26 move synchronously. The first screw rod 26 reciprocates vertically, and the first gear 29 moves synchronously. During the motion of the first gear 29, the first gear 29 is engaged with the first rack 28, so that the first gear 29 rotates. During the rotation of the first gear 29, the first screw rod 26 rotates synchronously; therefore, the first screw rod 26 can also rotate while the first screw rod 26 reciprocates vertically.

[0063] During the forward and reverse rotation of the first screw rod 26, the first nut seat 30 can continuously move toward or away from the position where the rubber tube 31 is located. During the movement of the first nut seat 30, the rubber tube 31 will continuously deform under the action of the first nut seat 30. During the deformation of the rubber tube 31, the diameter of the rubber tube 31 will be squeezed and reduced, thereby increasing the pressure in the rubber tube 31, that is, the water sprayed from the rubber tube 31 will enhance the force of the water when it is sprayed after the rubber tube 31 is deformed. Through the deformation of the rubber tube 31, the force of the water when it is sprayed can be adjusted, which, on the one hand, ensures that the water can more efficiently rinse the impurities, and on the other hand, the water can more comprehensively cool the grinding block 20 and the probe 11, that is, the effect of the water when it is sprayed is comprehensively enhanced.

[0064] At the same time, during the movement of the first nut seat 30, when the first nut seat 30 is misaligned with the connecting groove 33, water can flow into the chamber 32, and finally flow out through the atomizing nozzle 34 to act on the probe 11. Through the above movement, the water acting on the probe 11 is in the form of liquid and atomized liquid. When the atomized liquid acts on the probe 11, the contact area between the atomized liquid and the grinding block 20 and the probe 11 is more sufficient, and the heat is absorbed more rapidly, thereby achieving a better cooling effect on the grinding block 20 and the probe 11. In addition, when the atomized liquid is discharged, the atomized liquid can better reduce the dust generated by the grinding block 20 during grinding, so that the dust will not spread out, ensuring that the dust generated by the grinding block 20 during grinding will not pollute the environment or cause harm to the human body.

[0065] During the rotation of the first screw 26, the rotating shaft 37 rotates synchronously under the action of the belt 38. During the rotation of the rotating shaft 37, the second gear 39 rotates synchronously; during the rotation of the second gear 39, since the second gear 39 is meshed with the second rack 40, the second rack 40 can reciprocate along the length direction of the guide block 36. During the movement of the second rack 40, the cleaning block 41 moves synchronously.

[0066] During the movement of the cleaning block 41, the bristle block 42 moves synchronously. Through the lateral and vertical movements of the bristle block 42, the bristle block 42 can clean the positions where the polishing block 17 and the grinding block 20 have acted, so that the impurities remaining on the probe 11 are cleaned and finally fall to the bottom of the cleaning cylinder 12, which further improves the glossiness of the probe 11 and enhances the use effect of the probe 11. In addition, since the bristle block 42 can dry the positions where water has acted, the time that water stays on the probe 11 is shortened, ensuring that the probe 11 can be dried quickly, so that the probe 11 can efficiently enter the working state and improve the detection efficiency.

[0067] During the movement of the cleaning block 41, the wedge block 43 moves synchronously. During the movement of the wedge block 43, the rubber head 44 can be continuously deformed by the action of the wedge block 43 on the rubber head 44. During the deformation of the rubber head 44, the flowing water in the chamber 32 can be pressurized, so that the water flows faster, and after being sprayed out by the atomizing nozzle 34, the force is stronger and the range is wider, and the cooling effect and dust reduction effect are more significant.

[0068] During the rotation of the polishing block 17, the beating block 45 rotates synchronously. During the movement of the beating block 45, the beating block 45 beats the bristle block 42, causing the bristle block 42 to shake, thereby reducing the number of impurities adhering to the bristle block 42, so that the impurities eventually fall to the bottom of the cleaning cylinder 12, thereby improving the cleaning effect and cleaning efficiency of the bristle block 42. In addition, the bristle block 42 can be deformed, increasing the contact area between the bristle block 42 and the probe 11, so that the bristle block 42 can more efficiently and fully clean the probe 11, and comprehensively enhancing the cleaning effect of the bristle block 42.
