Detailed Description

Referring to fig. 1 to 10, the full-automatic intelligent detection equipment for voltage resistance between micro-motor commutator segments of the present invention comprises a frame 1, and is characterized in that an oscillating material automatic input module 2 and an inter-segment voltage resistance automatic test module 3 are disposed on the frame 1, and a material conveying module 4 is disposed on the frame 1 between a discharge end of the oscillating material automatic input module 2 and a feed end of the inter-segment voltage resistance automatic test module 3.

The material conveying module 4 comprises a first transverse conveying mechanism 5 and a second transverse conveying mechanism 6 which are arranged on the rack 1, wherein the first transverse conveying mechanism 5 and the second transverse conveying mechanism 6 are arranged at an upper and lower interval, and the conveying directions are mutually vertical. Of course, as an equivalent alternative, the first and second traverse conveyors may also be angled.

The feeding end of the first transverse conveying mechanism 5 corresponds to the discharging end of the oscillating material arranging automatic input module 2, and the discharging end of the second transverse conveying mechanism 6 corresponds to the feeding end of the inter-chip voltage-resistant automatic test module 3; a storage barrel 7 is arranged between the discharge end of the first transverse conveying mechanism 5 and the feed end of the second transverse conveying mechanism 6, a commutator hook position degree standard gauge hole 8 is arranged at the upper end of the storage barrel 7, and a plurality of positioning convex strips matched with the commutator hook position degree standard gauge hole 8 are arranged in the storage barrel 7; the commutator to be detected enters the storage barrel 7 after the position of the commutator to be detected is adjusted 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.

Specifically, the oscillating material arranging automatic input module 2 consists of an oscillating disc 2a and a material guide groove 2b obliquely arranged at the discharge end of the oscillating disc 2 a; the lower end of the material guide groove 2b is communicated with the feeding end of the material conveying module 4. The oscillating disc is the prior art, and is not the technical point to be protected by the present invention, and is not described herein again. The commutator is vibrated into a preset position shape by the oscillating disc and then output by the guide chute.

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 of the vertical support 5a along the horizontal direction.

Two first abdicating long holes 5c are arranged on the vertical support 5a corresponding to the stroke area of the first double-rod cylinder 5b in parallel along the horizontal direction at intervals.

The front surface of the vertical support 5a is provided with a first linear slide rail 5d along the horizontal direction, the first linear slide rail 5d is connected with a horizontal slide seat 5e which is arranged vertically in a sliding mode, the side edge of the horizontal slide seat 5e is connected with linkage blocks 5f which correspond to the first abdicating long holes 5c one by one, and the free end of each linkage block 5f penetrates through the corresponding first abdicating long hole 5c and is fixedly connected with the free end of the first double-rod cylinder 5 b.

Be provided with second double-pole cylinder 5g along vertical direction on horizontal sliding seat 5e, be connected with vertical slide 5h at second double-pole cylinder 5g piston rod free end, vertical slide 5h is through the second linear slide rail 5i along vertical setting and horizontal sliding seat 5e sliding connection, along the vertical pneumatic finger 5j that is provided with the centre gripping commutator that awaits measuring on vertical slide 5 h.

A horizontal seat 5k is arranged on the rack 1 below the pneumatic finger 5j, one end of the horizontal seat 5k is provided with a long groove 5l which is communicated with the discharge end of the oscillating material arranging automatic input module 2 and is adaptive to the commutator to be tested along the length direction, and the tail end of the long groove 5l is opposite to the initial position of the pneumatic finger 5 j.

The commutator hook position degree standard gauge hole 8 is positioned on a horizontal seat 5k on the side of the long groove 5l, and the material storage barrel 7 is positioned at the lower end of the horizontal seat 5 k; the horizontal slide 5e reciprocates between the long groove 5l and the commutator hook position degree gauge hole 8.

When the pneumatic reversing device works, the first double-rod cylinder extends out, the horizontal sliding seat drives the pneumatic finger to move to the tail end of the long groove and is opposite to the reverser at the tail end of the long groove, after the pneumatic finger is located in place, the second double-rod cylinder extends out, the pneumatic finger is driven by the vertical sliding seat to extend into the reverser hole and then transversely opened and kept, then the second double-rod cylinder is reset, the first double-rod cylinder is reset, the reverser on the pneumatic finger is driven to be above the reverser hook position standard hole 8, after the pneumatic finger is located in place, the second double-rod cylinder extends out to drive the pneumatic finger to move downwards, the cylinder at the lower part of the reverser is installed into the reverser hook position standard hole 8, the pneumatic finger is reset, the reverser is loosened, and the second double-rod cylinder is reset, namely. Repeating the above actions, and storing the commutator into the storage barrel through the commutator hook position degree standard hole.

Preferably, the problem that when the pneumatic finger lifts the commutator, the tail commutator and the adjacent commutator hook part interfere to cause the position of the latter commutator to be deformed is avoided. A first through hole is arranged on the side wall of the horizontal seat 5k corresponding to the commutator to be tested positioned at the tail end of the long groove 5l, and a feeding sensor 9 is arranged in the first through hole. The feed sensor is used for detecting whether the tail end of the long groove has the material.

A second through hole is arranged in parallel at the side edge of the first through hole, the second through hole is opposite to the centers of two adjacent to-be-tested commutators at the tail end of the long groove 5l, an isolating rod 10 is movably arranged in the second through hole in a penetrating manner, and the isolating rod 10 is connected with 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 out to isolate two adjacent commutators to be tested, and then the second double-rod cylinder 5g drives the pneumatic finger 5j to move upwards.

When the pneumatic finger stretches into the commutator and clamps the commutator, the first horizontal driving cylinder drives the isolating rod to stretch out, so that two adjacent commutators are spaced, and the phenomenon that the tail end commutator goes upwards and takes the adjacent commutator askew is avoided.

Further preferably, due to the hook structure at the edge of the upper end of the commutator, in order to ensure the accuracy of subsequent detection and avoid the problem that the detection cannot be carried out due to the incorrect angle of the commutator, a commutator hook position standard hole is skillfully arranged. However, the arrangement of the gauge hole causes the commutator to pass through the gauge hole due to slight incorrect angle, so that the commutator cannot pass through the gauge hole. In order to solve the technical problem, the lower end of a horizontal sliding seat 5e at the side edge of a pneumatic finger 5j is connected with a correction elastic sheet 12; the lower end of the correcting spring plate 12 is positioned at the upper side of the horizontal seat 5k, and the free end of the correcting spring plate is matched with a commutator to be tested at the opening part at the upper end 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 degree standard hole 8 and cannot fall down, the horizontal sliding seat 5e drives the correction elastic sheet 12 to contact the edge of the commutator to be tested to rotate when being reset, so that the hook at the upper end of the commutator to be tested corresponds to the commutator hook position degree standard hole 8 and falls down.

Through setting up the correction shell fragment at horizontal slide lower extreme ingeniously, when horizontal slide resets, can pull the commutator through the correction shell fragment and turn right the angle and then get into in the gauge hole. The contact between the correcting spring plate and the commutator is more or less, and the correcting spring plate can contact with the commutator and rotate for a certain angle when the horizontal sliding seat is reset according to the material of the correcting spring plate.

Further preferably, the problem that the commutator still cannot move downwards after the correcting elastic sheet is pulled due to poor hook position degree at the upper end of the commutator is solved.

A sensor 13 for bad hook position degree is arranged on the horizontal seat 5k corresponding to the proximal end part of the upper end of the commutator hook position degree standard gauge hole 8. This bad sensor of hook position degree is used for detecting simultaneously whether the storage cylinder has filled the commutator. In this embodiment, in the storage cylinder, 15 commutators to be tested can be stored simultaneously. When the storage cylinder is full of 15 commutators to be measured, the poor sensor of hook position degree sends a signal to the control terminal, and the control terminal controls the first transverse conveying mechanism to stop feeding.

A discharging cylinder 14 is obliquely arranged on the rack 1 at the side edge of the horizontal seat 5k, the free end of a piston rod of the discharging cylinder 14 is connected with an obliquely arranged discharging groove 14a through a connecting plate, and a matched poor hook charging barrel 15 is arranged at the discharging end of the discharging groove 14 a; under the initial condition, the upper end of the discharge chute 14a is positioned at the side edge of the standard hole 8 of the hook position degree of the commutator, when the sensor 13 with poor hook position degree detects the commutator to be tested with poor hook, the pneumatic finger 5j clamps the commutator to be tested and moves upwards, the discharge air cylinder 14 drives the discharge chute 14a to move to the upper part of the standard hole 8 of the hook position degree of the commutator, the pneumatic finger 5j loosens the commutator to be tested, and the commutator to be tested enters the charging barrel 15 with poor hook through the discharge chute 14 a.

After the inter-chip withstand voltage automatic test module performs detection for one cycle period, the sensor with poor hook position degree takes effect. The reason is that after the detection in one cycle period is completed, the commutator to be detected in the storage cylinder is output and enters the next cycle period, and the commutator to be detected in the storage cylinder is conveyed downwards. If the commutator is still detected in the gauge hole, the commutator hook in the gauge hole is abnormal, and the discharging cylinder is started to execute the fool-proof function. Thereby ensuring the continuous normal work of the equipment.

Preferably, the second transverse conveying mechanism 6 comprises 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 on the vertical plate 6b along the horizontal direction, the free end of a piston rod of the second horizontal driving cylinder 6c is connected with a horizontal pushing block 6d, a positioning hole 6e matched with the material storage barrel 7 is arranged on the horizontal pushing block 6d, and a hook positioning groove matched with a hook at the upper end of the commutator is formed at the edge of the positioning hole to ensure that the commutator to be tested does not shift in the conveying process, so that the subsequent pressure-resistant test can be smoothly carried out. The upper end surface of the transverse support 6a is provided with a guide limit block 6f matched with the horizontal material pushing block 6 d.

The lower end of the material storage barrel 7 is positioned on the feeding station in the middle of the transverse support 6a and is matched with the horizontal material pushing block 6 d; a discharging station is arranged on the transverse support 6a on the side edge of the commutator hook position degree standard gauge hole 8, and a yielding through hole 6g is arranged on the discharging station. The end face of the discharge end of the material storage barrel is matched with the upper end face of the horizontal pushing block, when the horizontal pushing block moves forwards, the upper end face of the horizontal pushing block on the rear side of the positioning hole blocks the discharge end of the material storage barrel, the material is prevented from continuously falling, and the purpose that the horizontal pushing block only conveys one material at a time is achieved.

The inter-chip withstand voltage automatic test module 3 is composed of a material lifting mechanism 16 arranged below the transverse support 6a and an withstand voltage automatic test device 17 arranged above the transverse support 6a and matched with the material lifting mechanism 16.
