Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of commutator production equipment, and particularly relates to a mica sheet feeding device of a slot-type commutator automatic sheet arranging machine. BACKGROUND

[0002] The slot-type commutator is one of the core components of a motor, and the structure requires that the mica sheet must be precisely inserted in a vertical state in the slot position between the commutator copper sheets, so as to ensure the insulation performance and stability during the operation of the motor. At present, in the assembly process of the domestic slot-type commutator, the feeding and insertion of the mica sheet still mainly relies on manual operation: the worker needs to manually pick up the mica sheet from the box, and after adjusting it to a vertical state, it is inserted into the corresponding slot position of the mold. Not only is the labor intensity extremely great, but also the production efficiency is extremely low, and it is difficult to meet the needs of large-scale production; more importantly, the consistency of manual operation is poor, and the verticality and insertion depth of the mica sheet are difficult to accurately control, and problems such as tilting and loosening are prone to occur, resulting in unqualified insulation performance of the commutator and high scrap rate.

[0003] With the improvement of the automation level of the manufacturing industry, some enterprises try to use simple mechanical structures to assist feeding, but there is a lack of mechanical feeding devices in the prior art that are specifically aimed at "vertical insertion of the mold": the existing auxiliary equipment can only realize the preliminary conveying of the mica sheet, and cannot complete the full-process automation from feeding to vertical positioning and batch insertion; some devices even need manual intervention to adjust the posture of the mica sheet, and cannot fundamentally replace manual operation; at the same time, due to the light and thin texture and small size of the mica sheet, the existing equipment is prone to posture deviation and falling during transfer, which further affects the precision and stability of the vertical insertion. In summary, the existing slot-type commutator assembly relies on manual vertical insertion of the mica sheet, and lacks corresponding mechanical feeding devices, resulting in low production efficiency and unstable product quality, which has become a key bottleneck restricting the upgrading of the slot-type commutator industry. Therefore, there is an urgent need in the field to develop a full-process automatic feeding device that can realize the feeding, posture maintenance and vertical insertion of the mica sheet into the mold, so as to fill the gap in the prior art and meet the needs of industrial production.

A plurality of (preferably four) push rods 29 are uniformly distributed on the side wall of the mica sheet containing seat 12 in the radial direction; a push rod lifting device is vertically installed on the bracket on the top surface of the device seat 8, the output end of the push rod lifting device is fixed with a push rod 30, the end of the push rod 30 is provided with a clamping groove, the push rod 30 is matched and clamped with the push rod 29, and through the lifting and displacement of the push rod 30, the push rod 29 and the mica sheet containing seat 12 can be driven to accurately index rotation.

[0034] The implementation principle of the embodiment is that when the feeding operation is performed, the mica sheet feeding device 5 orderly feeds the mica sheets to the front end conveying port. The qualified mica sheets fall through the falling channel 4 and are clamped into the mica sheet placing groove 2 of the mica sheet transfer seat 1 by the clamping plate device 18 (when the detection device 7 detects that the number of mica sheets on the negative pressure adsorption device 6 is less than the requirement, the negative pressure adsorption device 6 will run to the falling port 24, and all the mica sheets are loosened to fall into the collecting box). At this time, the clamping plate lifting cylinder 23 drives the cylinder seat 21 and the clamping plate 19 to rise and reset.

In this way, all the mica sheet insertion grooves 12 on the mica sheet containing seat 12 can be inserted with mica sheets. Since the mica sheets at this position cannot be separated from the mica sheet insertion groove 12 directly by gravity, when the overturning power 10 of the overturning mechanism 9 drives the overturning rod 11 to overturn from the vertical state to the horizontal state, the mica sheets at this time are in the vertical state waiting for extrusion. The above overturning process has been embodied in Figure 5 , the mica sheets are accurately conveyed to the groove type diverter of the sheet arranging position by overturning the mica sheet containing seat 12 to a preset angle by the overturning rod 11, to complete a feeding cycle. Finally, the push piece 36 of the extrusion device 10 completes the final pressure feeding, so that the mica sheets in the mica sheet containing seat 12 are extruded and pushed into the sheet inserting mold 15. When one sheet inserting mold 15 completes the insertion, the rotation of the sheet arranging turntable makes the next sheet inserting mold 15 in the state of waiting for mica sheet assembly.

[0035] The whole process realizes automatic feeding, positioning, transfer, pushing, overturning and indexing of the mica sheet, is accurate in positioning, efficient in conveying, effectively avoids deviation and falling of the mica sheet, and improves the quality and efficiency of the mica sheet.
