Description

Technical Field

[0001] The present invention relates to the technical field of motor stator processing equipment, and in particular to a segmented stator pre-pressing wire cutting machine and its operation method. Background Art

[0002] After the existing motor stator is wound with wire, the stator lead wires will leave extra lengths. Moreover, in most cases, manual scissors are needed to cut off the extra lengths of the stator lead wires. Therefore, removing the extra lengths of the stator lead wires often requires a lot of manpower and material resources, which limits the trimming of the stator lead wires of the motor and reduces the processing efficiency of the motor stator winding; manually measuring the length of the stator lead wires with a ruler and then using scissors to cut off the extra lengths of the lead wires seriously affects the quality of the parts; the trimming of the stator lead wires of the motor severely restricts the large-scale production of the motor stator and affects the benefits of the enterprise. At present, there is no effective wire cutting device specifically for the extra lengths of the stator lead wires of the motor, and many wire cutting machines for wire bodies on the market have complex mechanical structures and low automation levels. Therefore, the existing stator wire cutting machines should be improved to improve the wire cutting efficiency and product quality. Summary of the Invention

[0074] A workbench 11 for installing the above-mentioned mechanisms is formed on the frame 10.

[0075] The segmented stator 60 is formed by annularly piecing together multiple iron cores 61. Each iron core 61 has two leads 62 at its upper end. Multiple leads 62 on the outer sides of the multiple iron cores 61 surround to form an outer ring, and multiple leads 62 on the inner sides surround to form an inner ring. At the upper end of the stator 60, there is an end cover 63 sleeved on the plurality of iron cores 61. On the end cover 63, a wiring piece 64 for mating and connecting with each lead 62 is provided corresponding to each lead 62; the outer-ring lead pre-pressing mechanism 20 is used to press and fixedly connect the leads 62 in the outer ring with the corresponding wiring pieces 64 one by one, and the inner-ring lead pre-pressing mechanism 30 is used to press and fixedly connect the leads 62 in the inner ring with the corresponding wiring pieces 64 one by one.

[0076] It should be noted that the outer-ring lead pre-pressing mechanism 20 and the inner-ring lead pre-pressing mechanism 30 adopt the same mechanism, and the main difference lies in the different objects of action (the outer-ring lead pre-pressing mechanism 20 is used to perform extrusion operations on the leads 62 and wiring pieces 64 in the outer ring; the inner-ring lead pre-pressing mechanism 30 is used to perform extrusion operations on the leads 62 and wiring pieces 64 in the inner ring).

The horizontal sliding plate 213 is used to drive the overall horizontal movement of the wire-blocking component 23 and the wire-against component 24 to approach the leads 62 of the stator 60 to be processed. It is mainly used for large-range distance adjustment, while the cylinder driving of the wire-blocking component 23 and the wire-against component 24 is for precise adjustment of small-range distances.

[0079] The material stand 22 includes a support frame 221, a lifting drive device 222 (rodless cylinder), a rotation drive device 223 (motor) and a material discharging platform 224. The support frame 221 is installed beside the above-mentioned bracket 21; the lifting drive device 222 is installed on the support frame 221, and has a sliding seat 2221 that can slide vertically; the rotation drive device 223 is installed on the sliding seat 2221; the material discharging platform 224 is installed on the output end of the rotation drive device 223.

[0080] The two wire blocking assemblies 23 and the two wire abutting assemblies 24 are respectively installed on the above-mentioned bracket 21, and the two wire blocking assemblies 23 are symmetrical to each other, and the two wire abutting assemblies 24 are symmetrical to each other, and the wire blocking assemblies 23 and the wire abutting assemblies 24 on the same side cooperate with each other to press the lead wire 62 onto the terminal piece 64; the above-mentioned wire blocking assemblies 23 and the wire abutting assemblies 24 on the same side are installed on the horizontal sliding plate 213 on the same side.

When the pressing head 241 moves, the whole wire blocking assembly 23 moves accordingly, and the wire blocking head 231 passes through the main body part of the pressing head 241. On the one hand, it can improve the synchronization of the pressing and wire blocking actions, and on the other hand, it can make the overall structure more compact); and adjusting bolts 215 for restricting the moving distances of the respective two horizontal sliding plates 213 are respectively arranged on the opposite surfaces of the two horizontal sliding plates 213 facing each other, and the distance between the two horizontal sliding plates 213 is controlled within a predetermined range by adjusting the extending length of the adjusting bolts 215 to prevent rigid collision between the two.

[0082] The wire cutting mechanism 40 includes a support base 41, a material placing table 42, a pressing head assembly 43, a pneumatic shear 44 (pneumatic scissors), and a lateral driving assembly 45 for driving the pneumatic shear 44 to move closer to the lead 62 of the stator 60. The support base 41 is located beside the inner ring lead pre-pressing mechanism 30; the material placing table 42 is rotatably installed on the support base 41; the pressing head assembly 43 has a pressing head 433, and the pressing head 433 can be lifted and lowered above the material placing table 42. The pressing head assembly 43 further includes a pressing head support 431 and a vertical driving device 432 (cylinder). The pressing head support 431 is installed beside the above-mentioned support base 41; the vertical driving device 432 is installed on the support base 41 and has a vertically slidable vertical sliding seat 4321; the above-mentioned pressing head 433 is liftably installed on the vertical sliding seat 4321 and faces the above-mentioned material placing table. Specifically, an elastic seat 4322 that can vertically elastically expand and contract relative to the vertical sliding seat 4321 is installed on the vertical sliding seat 4321 of the vertical driving device 432 (the elastic lifting is realized by the cooperation of a guide rod 4323 and a spring 4324), the above-mentioned pressing head 433 is installed at the lower end of the elastic seat 4322, and the pressing head 433 can rotate relative to the elastic seat 4322 (bearing cooperation).

[0083] The lateral driving assembly is located beside the support base and includes a motor 451, a lead screw 452 (not shown in the figure), and a base 453. The motor is installed at the end of the base; the lead screw is inserted through the base and connected to the motor shaft end; the output end of the lateral driving assembly is a mounting plate, and the mounting plate is slidably matched with the base and connected to the lead screw; the motor drives the lead screw to rotate to drive the mounting plate to slide, and the above-mentioned pneumatic shear is installed on the mounting plate and is inclined upward and faces the material placing table.

[0084] In this embodiment, the wire cutting mechanism 40 includes two sets of air shears 44 and two sets of lateral driving components 45. The two sets of air shears 44 and the two sets of lateral driving components 45 are connected in a one-to-one correspondence and are respectively arranged on both sides of the support base 41, and the two sets of air shears 44 both face downward of the material placing table 42.

The two waste wire collecting grooves 46 are correspondingly located below the two air shears 44, and a wire collecting bin 461 is arranged below the two waste wire collecting grooves 46. The two sets of air shears 44 simultaneously perform wire cutting operations on the leads 62 of the stator 60 from both sides, improving the processing efficiency.

[0085] In addition, a rotary driving device 47 (motor) for driving the material placing table 42 to rotate is installed on the support base 41, and the material placing table 42 is connected to the output end of the rotary driving device 47. An angle sensor 48 for detecting the rotation angle of the material placing table 42 is also arranged on the support base 41. The angle sensor 48 can monitor the rotation angle of the material placing table 42 in real time so that the leads 62 of the stator 60 can pass through the air shears 44 in sequence. A material sensor 49 for detecting whether there is material on the material placing table 42 is also arranged on the support base 41.

[0086] The working principle of the wire cutting mechanism 40 is as follows: After the stator 60 is placed on the material placing table 42, the pressing head 433 descends to press the stator 60 tightly. The lateral driving component 45 drives the air shear 44 to approach the lead 62 of the stator 60 to perform a wire cutting operation on the lead 62. The material placing table 42 rotates to make different leads 62 on the stator 60 correspond to the air shear 44. During this process, the pressing head 433 rotates accordingly until all the leads 62 on the stator 60 are trimmed.

[0087] The above-mentioned outer ring lead pre-pressing mechanism 20, inner ring lead pre-pressing mechanism 30 and wire cutting mechanism 40 are arranged side by side at intervals.

The lead screw 5322 is connected to the shaft end of the motor 5321. The slider 5323 is installed on the lead screw 5322 and moves back and forth as the lead screw 5322 rotates. The transverse driving device 532 is installed on the longitudinal slide plate 521, and the transverse slide plate 531 is installed on the slider 5323 of the transverse driving device 532. The lifting component 54 includes a support plate 541 and a lifting driving device 542 (cylinder) for driving the support plate 541 to lift. The support plate 541 is installed on the transverse slide plate 531 in a liftable manner. The lifting driving device 542 is installed on the transverse slide plate 531 and the support plate 541, and the output end of the lifting driving device 542 is connected to the support plate 541. A plurality of clamping air cylinders 543 for clamping and placing the stator 60 on the outer ring lead pre-pressing mechanism 20, inner ring lead pre-pressing mechanism 30 and wire cutting mechanism 40 are arranged at intervals on the support plate 541. In this embodiment, three clamping air cylinders 543 are installed side by side at intervals on the support plate 541. Among them, the first clamping air cylinder 5431 can only have the functions of clamping and placing. The second clamping air cylinder 5432 and the third clamping air cylinder 5433 are rotary clamping air cylinders. The second clamping air cylinder 5432 is used to rotate and turn over the stator 60 with the lead 62 pressed on the wire cutting mechanism 40 so that the lead 62 of the stator 60 faces downwards for the air shear 44 to perform wire cutting operation on its lead 62. The third clamping air cylinder 5433 is used to rotate and turn over the stator 60 to the initial state after the wire cutting operation of the stator 60 lead 62 is completed, so as to facilitate the next process operation.

[0088] The longitudinal transfer component 52 is used to drive the clamping cylinder 543 to longitudinally enter or exit the outer ring lead pre-pressing mechanism 20, the inner ring lead pre-pressing mechanism 30 and the wire cutting mechanism 40 to carry out material picking and placing; the transverse transfer component 53 is used to drive the clamping cylinder 543 to transfer from the outer ring lead pre-pressing mechanism 20 to the inner ring lead pre-pressing mechanism 30, from the inner ring lead pre-pressing mechanism 30 to the wire cutting mechanism 40, and from the wire cutting mechanism 40 to the downstream equipment after clamping the stator 60; the lifting component 54 is used to drive the lifting action of the clamping cylinder 543 to use material picking and placing operations at different heights.

[0089] It should be noted that, in addition to the above-mentioned methods (motor, cylinder), the drive device and drive assembly can also be replaced by other drive sources that can achieve the same action.

[0090] The operation method of the block-type stator pre-pressing wire cutting machine includes the following steps:

[0091] S1. The stator to be processed is placed on the material seat of the outer ring lead preloading mechanism. The horizontal sliding plate and the vertical sliding plate cooperate to make the abutment block located at the rear side of the wiring piece. The wire blocking assembly drives the wire blocking head to approach the outer side of the lead. The material seat rotates, and the lead moves closer to the inner side of the wiring piece under the blocking action of the wire blocking head.

[0092] S2. The clamping head squeezes the wiring piece under the drive of the clamping drive cylinder to press the lead wire onto the wiring piece;

[0093] S3. After the corresponding lead wire is fixedly connected to the wiring piece, the material holder rotates so that the wire-contacting assembly and the wire-blocking assembly correspond to the new lead wire;

[0094] S4. After all the stator outer ring leads are pressed and fixed, the clamping cylinder of the transfer mechanism extends to the material seat, clamps the stator, and transfers it to the material seat of the inner ring lead pre-pressing mechanism. The inner ring lead pre-pressing mechanism repeats steps S1-S3 to press and fix the stator inner ring leads;

[0095] S5. After all the inner ring leads are pressed and fixed, the clamping cylinder of the transfer mechanism extends to the material seat, clamps the stator, rotates it and places it on the material placement table of the wire cutting mechanism. The two air shears are driven by the transverse drive assembly to approach the material placement table to cut the inner ring leads of the stator;

[0096] S6. After the wire cutting is completed, the stator is clamped by the clamping cylinder of the transfer mechanism, rotated and turned, and then transferred to the downstream.

[0097] The design focus of the present invention lies in forming a pre-pressing and wire-cutting device for a segmented stator by assembling an outer-ring lead pre-pressing mechanism, an inner-ring lead pre-pressing mechanism, a wire-cutting mechanism, and a transfer mechanism on a frame. This device realizes the automatic pressing and connection as well as wire-cutting operations for the outer-ring leads and inner-ring leads of the stator, making the lead processing of the stator completely automated, reducing a large amount of manual labor, and at the same time, improving production efficiency and product quality.

[0098] As described above, it is only a preferred embodiment of the present invention, and does not impose any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
