Description

Technical Field

[0001] The present invention relates to the technical field of motor winding equipment, and in particular to a gummed paper mechanism and an operation method thereof. Background Art

[0002] A motor includes a stator and a rotor. The stator is the stationary part of the motor and includes a stator core and a plurality of stator windings wound around stator teeth. A rotating magnetic field is generated through the stator windings. During the manufacturing process of the motor, a motor winding system is usually used to wind a wire, especially a copper wire with an insulating layer, around the stator teeth of the stator. Among them, first, a winding operation is performed on one stator tooth to form a stator winding, and then the winding operation is carried out to the next stator tooth through a transition wire in a transition wire groove located on the outer periphery to form the next stator winding until each stator tooth is wound with a stator winding. Since the transition wire usually extends out of the stator, it is easy to scratch and damage the transition wire during the assembly process of the stator. Therefore, it is necessary to perform a gummed paper operation on the transition wire to prevent the external insulating paint from being damaged due to scratching during the motor assembly process. However, currently during motor winding, the gummed paper operation on the transition wire part is usually manual, with low efficiency. Moreover, the gummed paper operation cannot achieve a unified standard and has a high defective rate. In view of this situation, it is necessary to design a mechanism for automatic gummed paper operation on the motor transition wire to solve the above problems. Summary of the Invention

[0003] In view of this, in view of the deficiencies existing in the prior art, the main purpose of the present invention is to provide a gummed paper mechanism and an operation method thereof. The gummed paper mechanism realizes the automatic operations of conveying, pulling, cutting, adhering, and completely squeezing and covering the gummed paper outside the wire, saving a large amount of manual labor, improving production efficiency. At the same time, the covering of the gummed paper is more regular, improving the product quality and qualification rate.

[0033] As shown in the present invention Figures 1 to 6 shown, an adhesive tape wrapping mechanism and an operation method, the adhesive tape wrapping mechanism includes a bracket 10, an adhesive tape conveying device 20, an adhesive tape cutting device 30, an adhesive tape pulling device 40 and an adhesive tape wrapping device 50, wherein:

[0034] The adhesive tape conveying device 20 includes an adhesive tape reel 21, an adhesive tape unwinding motor 22, a tension pulley 23 and an adhesive tape advancing assembly 24. The adhesive tape reel 21, the adhesive tape unwinding motor 22 and the tension pulley 23 are all installed on the bracket 10. The adhesive tape reel 21 is connected to the shaft end of the adhesive tape unwinding motor 22 through a pulley set. The adhesive tape bypasses the tension pulley 23 and is connected to the adhesive tape advancing assembly 24. The adhesive tape reel 21 is wound with the adhesive tape to be pasted. The adhesive tape unwinding motor 22 drives the adhesive tape reel 21 to rotate and unwind through the pulley set. The tension pulley 23 tensions the adhesive tape. The adhesive tape advancing assembly 24 feeds the adhesive tape forward while the adhesive tape reel 21 unwinds, so that the adhesive tape is continuously conveyed forward.

[0035] The adhesive tape progressive component 24 includes a tape clamping unit 241 and an adhesive tape progressive cylinder 242 for driving the tape clamping unit 241 to move back and forth. The tape clamping unit 241 is slidably mounted on the bracket 10 along the moving direction of the adhesive tape and is connected to the shaft end of the adhesive tape progressive cylinder 242. The tape clamping unit 241 includes a tape clamping cylinder 243 and a clamping block 244 mounted on the tape clamping cylinder 243. The tape clamping cylinder 243 drives the clamping block 244 to clamp or release the adhesive tape 60. When the adhesive tape 60 is progressively conveyed forward, the tape clamping cylinder 243 drives the clamping block 244 to clamp the adhesive tape 60, and the adhesive tape progressive cylinder 242 drives the tape clamping cylinder 243 to move forward to pull the adhesive tape 60 forward. Then, the tape clamping cylinder 243 drives the clamping block 244 to release the adhesive tape 60, and the adhesive tape progressive cylinder 242 drives the tape clamping cylinder 243 to retreat, repeating the above-mentioned pulling action of the adhesive tape 60 to realize the continuous forward conveyance of the adhesive tape 60.

[0036] The adhesive tape cutting device 30 is used to cut the adhered adhesive tape after the adhesive tape adheres to the outer wall of the wire 70. It includes a tape pressing component 31 and a cutting component 32. The tape pressing component 31 and the cutting component 32 are arranged corresponding to each other up and down and are located in front of the tape clamping unit 241. The tape pressing component 31 includes a pressing block 311 and a tape pressing cylinder 312 for driving the pressing block 311 to press down the adhesive tape for cutting. The pressing block 311 is mounted on the shaft end of the tape pressing cylinder 312. The cutting component 32 includes a cutting cylinder 321 and a cutting knife 322 mounted on the output end of the cutting cylinder 321. When cutting the adhesive tape, the tape pressing cylinder 312 drives the pressing block 311 to press down above the adhesive tape, and the cutting cylinder 321 drives the cutting knife 322 to move upward to cut the adhesive tape.

[0037] The adhesive tape pulling device 40 is located in front of the adhesive tape cutting device 30. After the adhesive tape extends out of the tape clamping unit 241, it is pulled by the adhesive tape pulling device 40. The adhesive tape pulling device 40 includes a tape clamping cylinder 41 and a pulling driving cylinder 42 for driving the tape clamping cylinder 41 to move back and forth. The tape clamping cylinder 41 is mounted on the output end of the pulling driving cylinder 42. The adhesive tape pulling device 40 is used to cooperate with the adhesive tape progressive component 24 to keep the adhesive tape in a straightened state during the forward conveyance process.

[0038] The adhesive tape wrapping device 50 is located between the adhesive tape cutting device 30 and the adhesive tape pulling device 40 and below both of them; the adhesive tape wrapping device 50 includes a tape wrapping unit 51 and a lateral driving unit 52 for driving the tape wrapping unit to move laterally to correspond to the adhesive tape. The tape wrapping unit 51 includes a tape wrapping base 511, a tape wrapping clamp 512, an opening clamp cylinder 513 for driving the tape wrapping clamp 512 to open, and a lifting driving device 514 for driving the tape wrapping clamp 512 and the opening clamp cylinder 513 to lift and lower. The lifting driving device 514 is installed on the base, and a driving plate 515 is installed at the output end of the lifting driving device 514. The tape wrapping clamp 512 is installed on the top of the driving plate 515, and the opening clamp cylinder 513 is installed at the lower end of the driving plate 515 and is located below the tape wrapping clamp 512. The lifting driving device 514 is a cylinder, and it can also be other driving forms, such as the form of a motor combined with a ball screw and a slider.

[0039] The lateral driving unit 52 includes a sliding table module 521 and a lateral adjusting device 522 installed at the output end of the sliding table module 521. The sliding table module 521 is located between the adhesive tape cutting device 30 and the adhesive tape pulling device 40, and it is a driving device formed by a servo motor combined with a ball screw and a slider. The lateral adjusting device 522 includes a support base 5221, three tape wrapping units installed on the support base 5221, and a rodless cylinder 5222. The purpose of setting three tape wrapping units is to correspond to three wire feeding devices. Each wire feeding device respectively conveys a wire 70. The three tape wrapping units 51 can be driven by the lateral adjusting device 522 to perform corresponding tape wrapping with the three wire feeding devices, improving the adhesion efficiency of the adhesive tape.

[0040] The three tape wrapping units 51 include a first tape wrapping unit 516, a second tape wrapping unit 517, and a third tape wrapping unit 518. Among them, the first tape wrapping unit 516 is fixedly installed at one end of the support base 5221, the rodless cylinder 5222 is installed at the other end of the support base 5221, the third tape wrapping unit 518 is slidably installed on the support base 5221 and is connected to the output end of the rodless cylinder 5222; the second tape wrapping unit 517 is located between the first tape wrapping unit 516 and the third tape wrapping unit 518. The rodless cylinder 5222 drives the third tape wrapping unit 518 to slide on the support base 5221, and the second tape wrapping unit 517 can move in the same direction under the lateral drive of the third tape wrapping unit 518. Moreover, an elastic element is connected between the second tape wrapping unit 517 and the support base 5221, and the elastic element can drive the second tape wrapping unit 517 to reset. The positions of the three tape wrapping units are different to adapt to the changes in the wire feeding position and the adhesive tape adhesion position, realizing flexible adjustment and fast tape sticking operation.

[0041] The rubber-coated fixture 512 includes two clamping blocks 53. The lower ends of the two clamping blocks 53 are hinged to each other. On the opposite sides of the upper ends of the two clamping blocks 53, there are steps 531 for embedding adhesive tapes. When the adhesive tape is placed, it can closely adhere to the steps 531. After the two clamping blocks 53 are closed, the steps 531 on the two clamping blocks 53 are joined together to form an embedding recess 532 for accommodating the adhesive tape. When pasting the adhesive tape, the adhesive tape is limited in the embedding recess 532 to avoid lateral displacement of the adhesive tape and ensure that the shape of the adhesive tape adhered to the wire 70 is neat and standard. On the steps 531 of the two clamping blocks 53, a plurality of adsorption holes 533 are respectively arranged towards the direction of adhesive tape placement. Inside the clamping block 53, an air passage is arranged corresponding to the plurality of adsorption holes 533, and the plurality of adsorption holes 533 are communicated with the air passage. On the outer wall of the clamping block 53, there is an air nozzle 534 connected to the air passage to provide vacuum pressure for the plurality of adsorption holes 533. The air nozzle 534 is connected to a vacuum pump. When the adhesive tape reaches the embedding recess 532, the adsorption holes 533 will generate suction to adsorb the adhesive tape in the embedding recess 532, so that the adhesive tape cutting device 30 can cut the adhesive tape to be pasted.

[0042] And on the opposite sides of the upper ends of the two clamping blocks 53, a plurality of rollers 54 are respectively arranged, and the rollers 54 on the two clamping blocks 53 correspond to each other one by one. Specifically, on the two clamping blocks 53, a plurality of installation grooves 535 are horizontally opened along the moving direction of the adhesive tape, and the plurality of rollers 54 are correspondingly installed in the plurality of installation grooves 535 through rotating shafts. The upper ends of the rollers 54 are flush with the steps 531, and the rollers 54 extend out of the steps 531 on the side close to the closing direction of the clamping blocks 53. Due to the special nature of the adhesive tape material, the glue on it is easily squeezed out. If the flat surfaces on the opposite sides of the two clamping blocks 53 are directly used to squeeze the adhesive tape, a large amount of glue is easily adhered to the inner walls of the two clamping blocks 53, resulting in that when the two clamping blocks 53 are opened, the adhesive tape is also adhered and driven to open, resulting in the failure of rubber-coating the adhesive tape. The purpose of arranging a plurality of rollers 54 on the two clamping blocks 53 is that when the two clamping blocks 53 squeeze and close the adhesive tape adhered to the wire 70 upward so that the adhesive tape completely wraps the wire 70, the rollers 54 and the adhesive tape are in rolling point contact extrusion, reducing the contact area and also avoiding the overflow of the glue in the adhesive tape during extrusion, thus effectively avoiding the phenomenon that the clamping blocks 53 adhere to the glue and drive the adhesive tape to open when the clips are opened, and improving the product quality and qualification rate. In addition, on the opposite sides of the two ends of the two clamping blocks 53, there are arc-shaped parts 536 with the same contour as the rollers 54. The arrangement of the arc-shaped parts 536 enables the ends of the two clamping blocks 53 to also have the effect of the rollers 54, avoiding large-area extrusion of the adhesive tape and causing the glue to overflow.

[0043] The ends of the two clamping blocks 53 are connected with a tension spring 55 for keeping the two clamping blocks 53 closed. The tension spring 55 is connected below the hinge shaft of the two clamping blocks 53, and the pulling force of the tension spring 55 causes the upper ends of the two clamping blocks 53 to remain in the closed normal state. A wedge-shaped push block is connected to the shaft end of the clamping cylinder 513. The lower ends of the two clamping blocks 53 are provided with arc-shaped convex parts facing each other. When the clamping cylinder 513 drives the wedge-shaped push block to move upward and enter between the lower ends of the two clamping blocks 53, the upper ends of the two clamping blocks 53 are opened.

[0044] The operation method of the rubberized paper mechanism includes the following steps:

[0045] S1. The rubberized paper feeding motor 22 drives the rubberized paper coil 21 to rotate and feed the paper. The rubberized paper moves forward under the drive of the tension pulley 23 and the rubberized paper feeding assembly 24.

[0046] S2. The rubberized paper pulling device 40 clamps the end of the rubberized paper and pulls it, so that the rubberized paper is located above the rubberized paper wrapping device 50.

[0047] S3. The lateral drive unit 52 drives the rubberized paper wrapping unit to move under the rubberized paper. The rubberized paper clamping fixture 512 moves upward under the drive of the lifting drive device 514 to correspond to the rubberized paper. The rubberized paper is located in the embedding recess 532 of the rubberized paper clamping fixture 512, and the suction holes 533 generate vacuum suction to adsorb the rubberized paper in the embedding recess 532.

[0048] S4. The rubberized paper cutting device 30 cuts the rubberized paper. The wire 70 enters above the rubberized paper, and the rubberized paper is pasted on the wire 70. The suction holes 533 stop vacuum adsorption.

[0049] S5. The lifting drive device 514 moves the rubberized paper clamping fixture 512 downward. At the same time, the clamping cylinder 513 drives the rubberized paper clamping fixture 512 upward to open and separate from the rubberized paper.

[0050] S6. The lifting drive device 514 drives the opened rubberized paper clamping fixture 512 upward, so that the rubberized paper adhered to the wire 70 is completely located between the two clamping blocks 53. As the rubberized paper clamping fixture 512 rises, the rubberized paper is gradually squeezed into a U shape by the rollers 54 on the two clamping blocks, and then wraps the wire 70.

[0051] S7. The clamping cylinder 513 retracts, the rubberized paper clamping fixture 512 closes, and the rubberized paper located above the wire 70 is squeezed by the rollers 54 on the two clamping blocks, and the wire 70 is completely wrapped by the rubberized paper.

[0052] S8. The clamping cylinder 513 drives the rubberized paper clamping fixture 512 to open again, takes away the wire 70 after removing the rubberized paper, and the lifting drive device 514 drives the rubberized paper clamping fixture 512 to descend and reset again.

[0053] The design focus of the present invention lies in that a rubber tape wrapping mechanism for motor wire is formed by integrating a rubber tape conveying device, a rubber tape cutting device, a rubber tape pulling device and a rubber tape wrapping device on a bracket. This rubber tape wrapping mechanism realizes the automated operations of rubber tape conveying, pulling, cutting, adhesion and complete extrusion and wrapping around the wire, saving a large amount of manual labor, improving production efficiency. At the same time, the wrapping of the rubber tape is more regular, improving product quality and qualification rate.

An operating method for the encapsulating paper mechanism according to any one of claims 1 to 6, characterized in that: The steps include: S1, the adhesive paper feeding motor drives the adhesive paper feeding tray to rotate and feed the adhesive paper, and the adhesive paper moves forward driven by the tensioning wheel and the adhesive paper advancing assembly; S2, the adhesive tape pulling device clamps the end of the adhesive tape and pulls it so that the adhesive tape is located above the adhesive tape wrapping device; S3, the lateral driving unit drives the adhesive paper unit to move to the bottom of the adhesive paper, and the adhesive paper clamp is driven by the lifting driving device to move upward to correspond to the adhesive paper, and the adhesive paper is located in the embedded concave position of the adhesive paper clamp, and the adsorption hole generates vacuum suction to adsorb the adhesive paper in the embedded concave position; S4, the adhesive tape cutting device cuts the adhesive tape, the wire material enters above the adhesive tape, the adhesive tape sticks to the wire material, and the adsorption hole stops vacuum adsorption; S5, the lifting drive device moves the rubber-wrapping clamp downward, and at the same time, the clamp opening cylinder drives the rubber-wrapping clamp upward to open and separate from the adhesive paper; S6. The lifting drive device drives the opened rubber coating clamp to move upward, so that the adhesive tape adhered to the wire is completely located between the two clamping blocks. As the rubber coating clamp rises, the adhesive tape is gradually squeezed into a U shape by the rollers on the two clamping blocks, thereby wrapping the wire; S7, the clamping cylinder withdraws, the rubber wrapping clamp closes, the adhesive tape above the wire is squeezed by the rollers on the two clamping blocks, and the wire is completely wrapped by the adhesive tape; S8, the clamp opening cylinder drives the rubber-wrapped clamp to open again, takes away the wire behind the rubber-wrapped paper, and the lifting drive device drives the rubber-wrapped clamp to descend and reset again.
