DETAILED DESCRIPTION
[0053] See also Figures 1 to 10 As shown, a fully automatic intelligent detection device for withstand voltage between segments of a micromotor commutator of the present invention comprises a frame 1, and is characterized in that an oscillating material automatic input module 2 and an inter-segment withstand voltage automatic test module 3 are provided on the frame 1, and a material conveying module 4 is provided on the frame 1 between the discharge end of the oscillating material automatic input module 2 and the feed end of the inter-segment withstand voltage automatic test module 3.
[0054] The material conveying module 4 includes a first transverse conveying mechanism 5 and a second transverse conveying mechanism 6 arranged on the frame 1. The first transverse conveying mechanism 5 and the second transverse conveying mechanism 6 are arranged at intervals and conveying directions are perpendicular to each other. Of course, as an equivalent alternative, the first transverse conveying mechanism and the second transverse conveying mechanism can also be at a certain angle.
[0055] The feeding end of the first transverse conveying mechanism 5 corresponds to the discharging end of the oscillating material sorting automatic input module 2, and the discharging end of the second transverse conveying mechanism 6 corresponds to the feeding end of the inter-sheet withstand voltage automatic testing module 3; a storage barrel 7 is arranged between the discharging end of the first transverse conveying mechanism 5 and the feeding end of the second transverse conveying mechanism 6, and a commutator hook position standard gauge hole 8 is arranged at the upper end of the storage barrel 7, and a plurality of positioning convex strips matching the commutator hook position standard gauge hole 8 are arranged inside the storage barrel 7; the commutator to be tested enters the storage barrel 7 after adjusting the hook position through the commutator hook position standard gauge hole 8, and the lower end of the storage barrel 7 is opposite to the feeding end of the second transverse conveying mechanism 6.
[0056] Specifically, the oscillating material automatic input module 2 is composed of an oscillating disk 2a and a first material guide trough 2b obliquely arranged at the discharge end of the oscillating disk 2a; the lower end of the first material guide trough 2b is connected to the feed end of the material conveying module 4. The oscillating disk is a prior art and is not a technical point to be protected by the present invention, so it will not be described in detail here. The commutator is vibrated into a predetermined position shape by the oscillating disk and output from the first material guide trough.
[0057] Preferably, the first transverse conveying mechanism 5 comprises a vertical support 5a fixed on the frame 1, and a first double-rod cylinder 5b is arranged on the back side of the vertical support 5a along the horizontal direction.
[0058] Two first long holes 5c are arranged in parallel and at intervals in the horizontal direction on the vertical support 5a corresponding to the stroke area of the first double-rod cylinder 5b.
[0059] A first linear slide rail 5d is arranged in the horizontal direction on the front side of the vertical support 5a, and a horizontal slide seat 5e arranged in the vertical direction is slidably connected to the first linear slide rail 5d. Linkage blocks 5f corresponding to the first long holes 5c are connected to the sides of the horizontal slide seat 5e. The free ends of the linkage blocks 5f pass through the corresponding first long holes 5c and are fixedly connected to the free ends of the first double-rod cylinder 5b.
[0060] A second double-rod cylinder 5g is arranged along the vertical direction on the horizontal slide 5e, and a vertical slide 5h is connected to the free end of the piston rod of the second double-rod cylinder 5g. The vertical slide 5h is slidably connected to the horizontal slide 5e through a second linear slide rail 5i arranged along the vertical direction, and a pneumatic finger 5j for clamping the commutator to be tested is arranged vertically on the vertical slide 5h.
[0061] A horizontal seat 5k is arranged on the frame 1 below the pneumatic finger 5j, and one end of the horizontal seat 5k is provided with a long groove 5l along the length direction, which is connected to the discharge end of the oscillating material automatic input module 2 and adapted to the commutator to be tested, and the end of the long groove 5l is opposite to the initial position of the pneumatic finger 5j.
[0062] The commutator hook position standard gauge hole 8 is located on the horizontal seat 5k on the side of the long slot 51, and the storage barrel 7 is located at the lower end of the horizontal seat 5k; the horizontal slide 5e reciprocates between the long slot 51 and the commutator hook position standard gauge hole 8.
[0063] During operation, the first double-rod cylinder extends, and the horizontal slide drives the pneumatic finger to move to the end of the long slot and face the commutator at the end of the long slot. After reaching the position, the second double-rod cylinder extends, drives the pneumatic finger to extend into the commutator hole through the vertical slide, and then opens and holds it horizontally. Then the second double-rod cylinder resets, and the first double-rod cylinder resets, bringing the commutator on the pneumatic finger to the top of the commutator hook position standard gauge hole 8. After reaching the position, the second double-rod cylinder extends, drives the pneumatic finger downward, and installs the lower column of the commutator into the commutator hook position standard gauge hole 8. The pneumatic finger resets, releases the commutator, and the second double-rod cylinder resets, and the commutator conveying action is completed. Repeat the above actions, and store the commutator in the storage barrel through the commutator hook position standard gauge hole.
[0064] Preferably, in order to avoid the interference between the end commutator and the adjacent commutator hook when the pneumatic finger lifts the commutator, thereby causing the position of the latter commutator to be deformed, a first through hole is provided on the side wall of the horizontal seat 5k corresponding to the commutator to be tested at the end of the long slot 5l, and a feed sensor 9 is provided in the first through hole. The feed sensor is used to detect whether there is material at the end of the long slot.
[0065] A second through hole is arranged parallel to the side of the first through hole, and the second through hole is opposite to the centers of two adjacent commutators to be tested at the end of the long slot 5l. An isolation rod 10 is movably inserted in the second through hole, and the isolation rod 10 is connected to a first horizontal driving cylinder 11; when the pneumatic finger 5j clamps the commutator to be tested, the first horizontal driving cylinder 11 drives the isolation rod 10 to extend to isolate the two adjacent commutators to be tested, and then the second double-rod cylinder 5g drives the pneumatic finger 5j upward.
[0066] When the pneumatic fingers extend into the commutator and clamp the commutator, the first horizontal driving cylinder drives the isolation rod to extend, so that two adjacent commutators are separated to prevent the end commutator from moving upward and causing the adjacent commutator to be skewed.
[0067] Further preferably, due to the hook structure at the upper edge of the commutator, a commutator hook position standard gauge hole is cleverly set to ensure the accuracy of subsequent detection and avoid the problem of being unable to detect due to the misalignment of the commutator angle. However, the setting of the gauge hole makes it impossible for the commutator to pass through the gauge hole due to a slight misalignment of the angle. In order to solve this technical problem, a correction spring 12 is connected to the lower end of the horizontal slide 5e on the side of the pneumatic finger 5j; the lower end of the correction spring 12 is located on the upper side of the horizontal seat 5k and the free end cooperates with the commutator to be tested at the upper end opening of the commutator hook position standard gauge hole 8; when the hook at the upper end of the commutator to be tested does not correspond to the commutator hook position standard gauge hole 8 and cannot fall, the horizontal slide 5e resets and drives the correction spring 12 to contact the edge of the commutator to be tested to rotate it, so that the hook at the upper end of the commutator to be tested corresponds to the commutator hook position standard gauge hole 8 and falls.
[0068] By cleverly setting a correction spring at the lower end of the horizontal slide, when the horizontal slide is reset, the correction spring can be used to pull the commutator to the correct angle and then enter the gauge hole. The amount of contact between the correction spring and the commutator depends on the material of the correction spring, as long as the correction spring can contact the commutator and rotate it to a certain angle when the horizontal slide is reset.
[0069] Further preferably, the problem that the commutator cannot move downward after the correction spring piece is pulled out due to poor positioning of the upper hook of the commutator is solved.
[0070] A hook position error sensor 13 is provided on the horizontal seat 5k corresponding to the upper proximal end of the commutator hook position standard gauge hole 8. The hook position error sensor is also used to detect whether the storage barrel is full of commutators. In this embodiment, 15 commutators to be tested can be stored in the storage barrel at the same time. When the storage barrel is full of 15 commutators to be tested, the hook position error sensor sends a signal to the control terminal, and the control terminal controls the first transverse conveying mechanism to stop loading.
[0071] A discharge cylinder 14 is obliquely arranged on the frame 1 on the side of the horizontal seat 5k, and the free end of the piston rod of the discharge cylinder 14 is connected to an obliquely arranged discharge chute 14a through a connecting plate, and a matching hook-defective barrel 15 is arranged at the discharge end of the discharge chute 14a; in the initial state, the upper end of the discharge chute 14a is located on the side of the commutator hook position standard gauge hole 8, when the hook position bad sensor 13 detects the commutator to be tested with bad bent hook, the pneumatic finger 5j clamps the commutator to be tested and moves upward, and the discharge cylinder 14 drives the discharge chute 14a to move above the commutator hook position standard gauge hole 8, and the pneumatic finger 5j releases the commutator to be tested, and the commutator to be tested passes through the discharge chute 14a and enters the hook-defective barrel 15.
[0072] After the inter-chip withstand voltage automatic test module completes one cycle of detection, the hook position bad sensor takes effect. This is because after one cycle of detection is completed, the commutator to be tested in the storage barrel will be output and enter the next cycle. At this time, the commutator to be tested in the storage barrel will be transported down. At this time, if it is detected that there is still a commutator in the gauge hole, it means that the commutator hook at the gauge hole is abnormal, and the unloading cylinder and other functions are started to perform foolproofing. This ensures that the equipment continues to work normally.
[0073] Preferably, the second transverse conveying mechanism 6 includes a transverse support 6a arranged on the frame 1, a vertical plate 6b is arranged at one end of the transverse support 6a, a second horizontal driving cylinder 6c is arranged in the horizontal direction on the vertical plate 6b, the free end of the piston rod of the second horizontal driving cylinder 6c is connected to a horizontal push block 6d, a positioning hole 6e matching with the storage barrel 7 is arranged on the horizontal push block 6d, and a hook positioning groove matching with the upper hook of the commutator is formed on the edge of the positioning hole to ensure that the commutator to be tested will not shift during the conveying process, thereby ensuring the smooth progress of the subsequent withstand voltage test. A guide limit block 6f matching with the horizontal push block 6d is arranged on the upper end surface of the transverse support 6a.
[0074] The lower end of the storage barrel 7 is located at the feeding station in the middle of the transverse support 6a and cooperates with the horizontal push block 6d; a discharging station is set on the transverse support 6a on the side of the commutator hook position standard gauge hole 8, and a clearance through hole 6g is set on the discharging station. The end face of the discharging end of the storage barrel cooperates with the upper end face of the horizontal push block. When the horizontal push block moves forward, the upper end face of the horizontal push block behind the positioning hole blocks the discharging end of the storage barrel to prevent the material from continuing to fall down, so as to achieve the purpose of the horizontal push block only conveying one material at a time.
[0075] The inter-sheet withstand voltage automatic test module 3 is composed of a material lifting mechanism 16 disposed below the transverse support 6 a and an automatic withstand voltage test device 17 disposed above the transverse support 6 a and coordinated with the material lifting mechanism 16 .
[0076] The lifting rod of the material lifting mechanism 16 passes through the clearance hole 6g to lift the commutator to be tested on the discharge station into the withstand voltage automatic testing device 17 for automatic testing.
[0077] During feeding, the second horizontal driving cylinder pushes the horizontal pushing rod forward, so that the positioning hole moves from the lower end of the storage barrel to the make way hole and stops, that is, it enters the feeding end of the material lifting mechanism. The material is lifted by the lifting rod of the material lifting mechanism and enters the automatic withstand voltage testing device and stops. At the same time, the second horizontal driving cylinder resets, driving the positioning hole to reset to the discharge end of the storage barrel, entering the next cycle of feeding preparation, and the equipment enters the inter-piece withstand voltage test mode.
[0078] Further preferably, in order to ensure the accurate movement of the horizontal push block between each station, a fine-tuning support 6h is provided on the transverse support 6a of the storage barrel 7 close to the vertical plate 6b, and a limit plate 6i is provided between the fine-tuning support 6h and the vertical plate 6b, and the limit plate 6i is provided at the contact portion between the free end of the piston rod of the second horizontal driving cylinder 6c and the horizontal push block 6d; a first limit screw 6j opposite to the limit plate 6i is threadedly connected on the vertical plate 6b, and a second limit screw 6k opposite to the limit plate 6i is threadedly connected on the fine-tuning support 6h, when the limit plate 6i contacts the first limit screw 6j, the positioning hole 6e is opposite to the storage barrel 7, and when the limit plate 6i contacts the second limit screw 6k, the positioning hole 6e is opposite to the clearance through hole 6g. Through the fine adjustment of the first limit screw and the second limit screw, the extension position and the retraction position of the second horizontal driving cylinder can be accurately guaranteed.
[0079] Further preferably, in order to realize that the commutator can be automatically outputted after detection without adding a complex mechanical structure, a guide limit groove 61 is provided on the upper end surface of the transverse support 6a along the length direction, and a guide limit block matching the guide limit groove 61 is provided at the bottom of the horizontal push block 6d. The guide limit groove not only serves to keep the horizontal push block moving accurately in a straight line, but also serves to guide and limit the horizontal movement of the commutator, so that the commutator maintains a straight line motion during movement.
[0080] A defective product output station and a qualified product output station are sequentially arranged on the transverse support 6a on the side of the material discharging station away from the second horizontal driving cylinder 6c.
[0081] The qualified product output station is located at the end of the transverse support 6a, at which a qualified product discharge slope 6m is provided, a second material guide trough 6n is provided on the frame 1 on the side of the qualified product discharge slope 6m, and a qualified product collection basket 6o is provided below the second material guide trough 6n.
[0082] A through T-shaped guide groove 6p is provided along the width direction of the transverse support 6a at the defective product output station, and a defective product output hole 6q is provided at the bottom of the T-shaped guide groove 6p and on the extension path of the guide limit groove 61; the defective product output hole 6q is connected to a defective product collection basket 6r. It is common knowledge in the art that the defective product output hole and the defective product collection basket are connected directly or by pipeline according to the equipment location, space and other conditions.
[0083] A discharge control slider 18 is movably arranged in the T-shaped guide groove 6p, and the discharge control slider 18 is connected to a third horizontal driving cylinder 18a; the upper end surface of the discharge control slider 18 is flush with the upper end surface of the transverse support 6a and is provided with a qualified product output guide groove 18b that matches the guide limit groove 6l.
[0084] The positioning hole 6e is located in the middle of the horizontal pusher block 6d, and a second long hole 6s communicating with the positioning hole 6e is provided at one end of the horizontal pusher block 6d away from the second horizontal driving cylinder 6c, and the width of the second long hole 6s is greater than the outer diameter of the lifting rod of the material lifting mechanism 16. This can prevent the horizontal pusher block from interfering with the lifting rod when moving horizontally.
[0085] When the positioning hole 6e is opposite to the clearance hole 6g, the front end of the horizontal pusher block 6d is located at the qualified product discharge slope 6m; when the positioning hole is opposite to the unloading end of the storage barrel, the front end of the horizontal pusher block is located between the clearance hole and the storage barrel. The clearance hole becomes a shared station for the input to be tested and the tested output.
[0086] During operation, after the withstand voltage automatic test device 17 has finished testing, the lifting rod descends, so that the tested commutator returns to the feeding end of the material lifting mechanism. At this time, the second horizontal driving cylinder drives the horizontal push block forward, and pushes the tested commutator to the feeding end of the material lifting mechanism, that is, the shared station, through the positioning hole. At the same time, the front end of the horizontal push block pushes the tested commutator located at the shared station to the unqualified product output station or the qualified product output station for corresponding output according to the test results.
[0087] In the initial state, the discharge control slider 18 is located in the T-shaped guide groove 6p and the qualified product output guide groove 18b is opposite to the guide limit groove 6l. The qualified products move to the qualified product discharge slope 6m through the qualified product output guide groove 18b and are output.
[0088] When defective products are detected, the third horizontal driving cylinder 18a drives the discharging control slider 18 to move so that the defective product output hole 6q is exposed, and the defective products are transported to the defective product collection basket 6r through the defective product output hole 6q.
[0089] By adopting this structure, the second transverse conveying mechanism can realize the pressure resistance test feeding and conveying before the commutator test and the output of qualified and unqualified products after the test.
[0090] Preferably, in this embodiment, the material lifting mechanism 16 includes a lifting bracket 16a, on which a servo motor 16b is arranged, and the power output shaft of the servo motor 16b is meshed with a lifting rack 16c through a gear, and a lifting rod 16d is arranged at the upper end of the lifting rack 16c; in the initial state, the upper end of the lifting rod 16d is located in the clearance through hole 6g, and when the commutator to be tested reaches the shared station, the lifting rod 16d rises to lift the commutator to be tested to the test station of the withstand voltage automatic test device 17. When the test is completed, the lifting rod drives the tested commutator to reset to the clearance through hole, and the tested commutator is output while the horizontal push rod is feeding.
[0091] Preferably, in this embodiment, the automatic withstand voltage test device 17 includes a test bracket 17a fixed on the frame 1, and a clutch mechanism 19 is arranged on the test bracket 17a, and a plurality of test seats 17b corresponding to the number of commutator segments to be tested are distributed circumferentially on the clutch mechanism 19, and two probes 17c corresponding to the commutator segments to be tested are arranged vertically at intervals on each test seat 17b, and each probe 17c is connected to an external power supply circuit; the commutator to be tested is lifted to the test working position by the lifting rod of the material lifting mechanism 16, and each probe 17c cooperates with the test seat 17b through the clutch mechanism 19 to realize contact and separation with the commutator segments of the commutator to be tested.
[0092] Further preferably, the clutch mechanism 19 includes a test base plate 19a arranged on the test bracket 17a, and a clutch 19c is rotatably connected to the test base plate 19a through a guide sleeve 19b; during testing, the lifting rod of the material lifting mechanism 16 passes through the inner hole of the guide sleeve 19b to lift the commutator to be tested to the upper side of the clutch 19c.
[0093] A guide plate 19d fixedly connected to the test bracket 17a is arranged above the clutch 19c, and a clearance hole corresponding to the commutator to be tested is arranged at the center of the guide plate 19d; guide holes 19e corresponding to each test seat 17b are arranged on the guide plate 19d, and each guide hole 19e is arranged radially with the clearance hole on the guide plate 19d as the center.
[0094] The clutch 19c is composed of a clutch rotating disk 19f rotatably connected to the guide sleeve 19b and a rotating cylinder 19g hinged to the edge of the clutch rotating disk 19f; the free end of the rotating cylinder 19g is hinged to the test bracket 17a.
[0095] On the clutch rotating disk 19f, arc guide long holes 19h corresponding to each test seat 17b are evenly spaced along the circumferential direction of the guide sleeve 19b, and a guide pin 17d matching the arc guide long hole 19h is provided at the bottom of the test seat 17b.
[0096] When the rotating cylinder 19g drives the clutch rotating disk 19f to rotate forward and reverse, the test seat 17b realizes the contact and separation of the probe 17c and the commutator segment of the commutator to be tested under the cooperation of the guide plate 19d and the clutch rotating disk 19f.
[0097] During the withstand voltage test, the rotating cylinder drives the clutch turntable to rotate, the probe contacts the commutator segment to be tested, and the control terminal starts the self-test system to check whether the probe contact is good. After the self-test is completed, the self-starting power supply enters the inter-segment withstand voltage automatic test working state mode. After 1 second, the rotating cylinder contracts and the probe separates from the commutator segment. The conventional requirement for the dielectric strength test between commutator segments is 500 volts for 1 second. Of course, the time and voltage can also be adjusted according to customer requirements. The step-up and step-down drive the tested commutator down to the shared workstation, and the second lateral conveying mechanism inputs the commutator to be tested and outputs the tested commutator.
[0098] Further preferably, a gravity-type auxiliary positioning rod 20 is vertically movably arranged on the test bracket 17a above the guide plate 19d, which is opposite to the lifting rod 16d on the material lifting mechanism 16. In the initial state, the lower end of the gravity-type auxiliary positioning rod 20 is located on the upper side of the positioning hole 6e. When the lifting rod 16d lifts the commutator to be tested, the gravity-type auxiliary positioning rod 20 cooperates with the lifting rod 16d to clamp and fix the commutator to be tested.
[0099] By setting up a gravity-type auxiliary positioning rod, which cleverly cooperates with the lifting rod, the commutator is guaranteed to be stable and not shifted during the entire process of entering and exiting the withstand voltage automatic test device, which greatly improves the stability of the equipment operation. This is because during the transportation process, once the commutator has a slight displacement and rotation, it may seriously affect the subsequent precise contact between the probe and the commutator segment, thereby affecting the test.

The stroke of the cylinder and the motor, etc. can be controlled by the sensor, which is common knowledge in the art. At the same time, the connection mode and working principle of the PLC controller and each sensor, cylinder and motor are also common knowledge in the art, which is not the technical point to be protected by the present invention and will not be repeated here.
