Description

Technical Field

[0001] The present invention relates to a flanging paper inserting machine, belonging to the technical field of new energy motor processing. Background Art

[0002] At present, an insulating paper is required to maintain insulation between the coil inside the stator of a new energy motor and the paper inserting groove. The insulating paper needs to be pre-inserted into the stator before the coil is inserted into the paper inserting groove. Currently, when inserting the insulating paper into the paper inserting groove, the insulating paper needs to be first folded into a specific shape adapted to the paper inserting groove, and then inserted into the paper inserting groove so as to insert the coil, and the insulating paper in the specific shape wraps around the periphery of the coil to isolate the coil and the inner wall of the paper inserting groove to achieve the insulation effect.

[0003] However, when the formed insulating paper is inserted, due to inaccurate stroke control, the insulating paper is prone to deformation or cannot be inserted to the accurate position, which affects the paper inserting quality and causes insulation failure between the coil and the stator.

When the paper strip to be processed is cut, it is used for pressing and fixing one end of the paper strip to prevent the paper strip from shifting during cutting and affecting the cutting size; Further, the paper inserting slot includes a paper folding and forming base at the bottom. On both sides of the top of the paper folding and forming base, a right folding edge die and a left paper folding die are respectively arranged.

It is used for the protruding part of the flanging of the strip to be processed in the previous process to pass through; Further, the flanging and paper inserting machine further includes a buffer mechanism, which is arranged at the rear side of the paper feeding drive mechanism and includes a buffer fixing plate. A buffer slide rail is fixedly installed on the surface of the buffer fixing plate along the vertical direction. A buffer slider is slidably sleeved on the surface of the buffer slide rail. A buffer hanging rod is arranged at the front end of the buffer slider along the horizontal direction. The buffer hanging rod includes two parallel long rods with a gap therebetween to ensure that the strip to be processed can pass through.

An upper inductor and a lower inductor are respectively fixedly installed at the upper and lower ends of the inductor mounting plate. Both the upper inductor and the lower inductor are in signal connection with the paper feeding drive mechanism. In actual work, when there is no need to feed paper to the subsequent process, there is no tension support of the strip to be processed on the buffer hanging rod. At this time, the buffer slider will fall downward under the action of gravity. When it falls to the lower inductor, the inductor is triggered. At this time, the lower inductor transmits a signal to the paper feeding drive mechanism to stop feeding paper, so as to restore the tension of the strip to be processed. Under the action of the tension of the strip to be processed, it will drive the buffer hanging rod and the buffer slider to move upward until it reaches the upper inductor. At this time, it indicates that the tension of the strip to be processed is excessive and paper feeding needs to continue. Therefore, the upper inductor continues to transmit the induction signal back to the paper feeding drive mechanism to prompt it to continue feeding paper. Further, the indexing and rotating mechanism is arranged on one side of the outlet of the cutting and paper pushing mechanism and includes an indexing mounting plate.

One side of the push plate fixing plate is in transmission connection with a push plate lifting cylinder.

[0009] Further, a paper feeding servo mechanism is also provided at the rear side of the preforming mechanism. The paper feeding servo mechanism includes a paper feeding motor mounting base, on which a paper feeding motor is fixedly installed.

A pressing block cylinder mounting frame is erected above the paper feeding base. A pressing block cylinder is fixedly installed on the top surface of the pressing block cylinder mounting frame. The output end of the bottom of the pressing block cylinder is drivingly connected to a paper feeding pressing block, and the paper feeding pressing block and the paper feeding base are matched with each other. A paper feeding strip channel is formed between the two. After the to-be-processed strip after chamfering and indentation in the previous process is processed and enters the paper feeding strip channel, it is clamped by the paper feeding pressing block and the paper feeding base and transported to the next process for continuous processing under the drive of the paper feeding motor; Further, a guiding mechanism is also provided behind the buffer mechanism. The guiding mechanism includes a horizontally erected guiding cross bar, on which a guiding pressing piece is fixedly installed through two mounting rings. The distance between the two mounting rings is greater than the width of the to-be-processed strip. The distance between the guiding cross bar and the guiding pressing piece is greater than the thickness of the to-be-processed strip. By passing the to-be-processed strip through between the guiding cross bar and the guiding pressing piece and under the limiting action of the two mounting rings, the to-be-processed strip is kept flat and correctly conveyed in the direction of the next process; Further, the paper feeding driving mechanism includes a paper strip guiding rod, and a paper feeding driving roller is also erected behind the paper strip guiding rod. A paper feeding auxiliary roller is arranged parallel to the bottom of the paper feeding driving roller. One end of the paper feeding driving roller is drivingly connected to the output end of a paper feeding driving motor.

[0010] By means of the above solution, the present invention has at least the following advantages: The flanging and paper inserting machine of the present invention realizes full-automatic paper feeding, indentation, chamfering, paper folding, flanging, and paper inserting, with high production efficiency. Moreover, the formed strip finished product with a flanging structure formed by automatic folding can control the insertion stroke length of the insulating paper through the fixed length of the flanging structure when inserted into the to-be-inserted stator coil hole, so as to realize the precise insertion of the insulating paper, avoid problems such as deformation of the insulating paper or inability to be inserted to the accurate position, affecting the paper inserting quality and resulting in insulation failure between the coil and the stator, and has a broad application prospect.

[0015] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0016] See also Figure 1 A flanging and inserting paper machine according to a preferred embodiment of the present invention comprises a working platform 1, a paper feeding driving mechanism 2 is arranged at the front end of the surface of the working platform 1, and a chamfering mechanism 5, a longitudinal creasing mechanism 6, a transverse creasing mechanism 7, a preforming mechanism 8, a cutting and pushing paper mechanism 10 and a dividing and rotating mechanism 11 are arranged in sequence behind the paper feeding driving mechanism 2; See also Figure 2 The paper feeding drive mechanism 2 includes a paper strip guide rod 21 for guiding and tightening the paper strip 12 to be processed; a paper feeding drive roller 22 is also set behind the paper strip guide rod 21, and a paper feeding auxiliary roller 23 is set at the bottom of the paper feeding drive roller 22 in parallel with it, and one end of the paper feeding drive roller 22 is connected to the output end of the paper feeding drive motor 24 by transmission, and the paper feeding drive roller 22 is driven to rotate by the paper feeding drive motor 24, and the paper strip 12 to be processed is driven to move to the next process by the squeezing friction of the paper feeding auxiliary roller 23; See also Figure 3The flanging and inserting paper machine also includes a cache mechanism 3, which is arranged at the rear side of the paper feeding drive mechanism 2, including a cache fixing plate 31, a cache slide rail 32 is fixedly installed on the surface of the cache fixing plate 31 in the vertical direction, and a cache slider 33 is slidably sleeved on the surface of the cache slide rail 32, and a cache suspension rod 34 is arranged at the front end of the cache slider 33 in the horizontal direction, and the cache suspension rod 34 includes two long rods parallel to each other, and a gap is left between the two long rods to ensure that the paper strip 12 to be processed passes through, and the top of the cache slider 33 is suspended on the top of the cache slide rail 32 by a buffer spring 38, and a sensor mounting plate 35 is fixedly installed on the side edge of the cache fixing plate 31, and an upper sensor 36 and a lower sensor 36 are fixedly installed at the upper and lower ends of the sensor mounting plate 35, respectively. The upper sensor 36 and the lower sensor 37 are both connected to the paper feeding drive mechanism 2 by signal. In actual work, if there is no need to feed paper to the subsequent process, the buffer suspension rod 34 is not supported by the tensioning force of the paper strip 12 to be processed. At this time, the buffer slide 33 will fall downward under the action of gravity. When it falls to the lower sensor 37, the sensor is triggered. At this time, the lower sensor 37 transmits a signal to the paper feeding drive mechanism 2 to stop feeding paper, thereby restoring the tensioning force of the paper strip 12 to be processed. Under the action of the tensioning force of the paper strip 12 to be processed, the buffer suspension rod 34 and the buffer slide 33 will be driven to move upward until they reach the upper sensor 36. At this time, it indicates that the paper strip 12 to be processed is over-tightened and needs to continue feeding paper. Therefore, the upper sensor 36 continues to transmit the sensing signal back to the paper feeding drive mechanism 2 to prompt it to continue feeding paper. See also Figure 4 A guide mechanism 4 is further provided at the rear of the buffer mechanism 3. The guide mechanism 4 includes a transversely mounted guide crossbar 41.

The distance between the two mounting rings 42 is greater than the width of the paper strip 12 to be processed. The distance between the guide crossbar 41 and the guide pressing plate 43 is greater than the thickness of the paper strip 12 to be processed. By passing the paper strip 12 to be processed between the guide crossbar 41 and the guide pressing plate 43 and under the limiting action of the two mounting rings 42, the paper strip 12 to be processed is kept flat and correctly transported to the next process direction; See also Figures 5 - 7, the chamfering mechanism 5 includes a chamfering mounting frame 51. On the bottom of the chamfering mounting frame 51, a right chamfering block 52 and a left chamfering block 53 are symmetrically arranged on the left and right.

On the top of the chamfering mounting frame 51, a chamfering cylinder 55 is fixedly arranged. At the output end of the bottom of the chamfering cylinder 55, a chamfering pressing plate 56 is connected by transmission. On the chamfering pressing plate 56, two chamfering tool seats 57 are symmetrically installed. At the bottom of each chamfering tool seat 57, a chamfering tool 58 is vertically installed downward.

[0017] The working principle of the present invention is as follows: During the actual use of the flanging and paper inserting machine of the present invention, first, the strip guiding rod 21 guides the strip 12 to be processed in the tensioning paper tray, and feeds the strip 12 to be processed between the paper feeding driving roller 22 and the paper feeding auxiliary roller 23. The paper feeding driving roller 22 is driven to rotate by the paper feeding driving motor 24. With the extrusion friction of the paper feeding auxiliary roller 23, the strip 12 to be processed is driven to move towards the buffer mechanism 3 process, ensuring that the strip 12 to be processed passes through the buffer hanging rod 34. When there is no need to feed paper to the subsequent process, there is no support for the tension of the strip 12 to be processed on the buffer hanging rod 34. At this time, the buffer slider 33 will fall downward under the action of gravity. When it falls to the lower inductor 37, the inductor is triggered. At this time, the lower inductor 37 transmits a signal to the paper feeding driving mechanism 2 to stop feeding paper, thereby restoring the tension of the strip 12 to be processed. Under the action of the tension of the strip 12 to be processed, the buffer hanging rod 34 and the buffer slider 33 will move upward until they reach the upper inductor 36. At this time, it indicates that the tension of the strip 12 to be processed is excessive and paper feeding needs to continue. Therefore, the upper inductor 36 transmits the induction signal back to the paper feeding driving mechanism 2 to prompt it to continue feeding paper. The strip 12 to be processed sent out passes through between the guiding cross bar 41 and the guiding pressing piece 43, and under the limiting action of the two mounting rings 42, the strip 12 to be processed is kept flat and correctly conveyed into the chamfering mechanism 5. The chamfering knife 58 moves up and down in the knife groove 521 to chamfer the strip 12 to be processed passing through the chamfering strip channel 54. After chamfering, it enters the longitudinal indentation paper strip channel 621 of the longitudinal indentation mechanism 6. Four indentation ridges 663 matching the longitudinal indentation channels 623 are provided on the surface of the indentation wheel body 662 and roll over the surface of the strip 12 to be processed. With the cooperation of the longitudinal indentation channels 623, four creases are rolled on the surface of the strip 12 to be processed, facilitating the subsequent folding operation in the processing process. After longitudinal indentation, it enters the transverse indentation mechanism 7. The strip 12 to be processed entering from the transverse indentation paper strip channel 71 passes through the upper surface of the lower indentation block 76. A transverse indentation is punched on the surface of the strip 12 to be processed through the cooperation of the transverse indentation groove 751 and the transverse indentation ridge 761, facilitating the subsequent flanging. The strip 12 to be processed after chamfering and indentation continues to be conveyed into the preforming mechanism 8, and successively passes through the vertical forming die 821, the inner flanging forming die 822 and the inner folding forming die 823. The chamfered edge of the strip 12 to be processed originally in a planar state is folded downward to a state perpendicular to the paper surface, and then the chamfered edge of the strip 12 to be processed folded to a state perpendicular to the paper surface by the vertical forming inclined surface 8211 is turned inward by 45°. Finally, through the inner folding guiding ramp 8231, the chamfered edge of the strip 12 to be processed with the chamfered edge turned inward by 45° in the previous step is guided into the inner folding forming inclined surface 8232 at the preforming paper strip channel 85, and then the chamfered edge is folded inward by using the inner folding forming inclined surface 8232. Finally, the upper pressing wheel 842 and the lower pressing wheel 843 at the outlet of the preforming paper strip channel 85 are used to extrude and preform the flanging; for the specific flanging process of the strip 12 to be processed, please refer toFigure 13 ; After preforming is completed, the to-be-processed paper strip 12 after preforming enters the paper feeding strip channel 971, and is clamped by the paper feeding pressing block 97 and the paper feeding base 96 and transported to the cutting and pushing paper mechanism 10 driven by the paper feeding motor 94. First, the downward pressing fixing cylinder 1023 drives the downward pressing fixing block 1026 to press one end of the fixed paper strip to prevent the paper strip from shifting during cutting and affecting the cutting size. Then, the cutting blade 1024 is used to cut the to-be-processed paper strip 12 to a preset length. Finally, the folding cylinder 1022 drives the folding pressing piece 1025 to press down to press the cut to-be-processed paper strip 12 into the folding groove 104 for folding preforming. After folding preforming, the pushing paper mechanism 103 is started to push the to-be-processed paper strip 12 after folding preforming from the paper inserting groove 105 to the indexing and rotating mechanism 11. During the process of pushing the paper, first, the paper entering guiding surface 1056 guides the to-be-processed paper strip 12 when it is pushed into the right folding edge mold 1052 and the left folding paper mold 1054. Subsequently, the right folding paper inclined surface 10521 is used to fold the right paper edge of the folded to-be-processed paper strip 12 inward at 90°. Then, the left folding paper inclined surface 10541 is used to fold the left paper edge of the folded to-be-processed paper strip 12 inward at 90° to overlap with the right inward folded paper edge to form a formed paper strip finished product 13 as shown in Figure 16 ; Finally, it is pushed by the pushing paper ejector rod 1034 into the coil hole of the fixed stator to be inserted 14 installed on the indexing and rotating mechanism 11, and the indexing and rotating motor 118 drives the stator to be inserted 14 to index and rotate, facilitating the accurate and continuous pushing and inserting of the formed paper strip finished product 13 into the stator to be inserted 14. And because the formed paper strip finished product 13 with a flanging structure formed by automatic folding in the present invention, when it is inserted into the coil hole of the stator to be inserted 14, the travel length of the inserted insulating paper can be controlled by the fixed length of the flanging structure, so as to realize the accurate insertion of the insulating paper, avoid the problems of deformation of the insulating paper or inability to be inserted to the accurate position, affecting the paper insertion quality and resulting in insulation failure between the coil and the stator.

[0018] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
