Description

Technical Field

[0001] This application relates to the field of motor winding technology, and in particular to a fully automatic twelve-station self-adhesive coil winding machine. Background Technology

[0002] The coil winding process is an important step in motor manufacturing, especially in the coil winding of linear motors, where the coil arrangement and number of turns directly affect the output efficiency of the linear motor.

[0003] Currently, the winding of the moving coil mainly relies on workers starting a winding machine to follow a predetermined winding pattern. Generally, one end of the wire is fixed first, and then the winding begins on the winding die. After winding to the set length, the wire is cut by a cutting mechanism. However, the above winding method is still relatively inefficient. Summary of the Invention

[0004] To improve the winding efficiency of coils, this application provides a fully automatic twelve-station self-adhesive coil winding machine.

[0005] The fully automatic twelve-station self-adhesive coil winding machine provided in this application adopts the following technical solution:

[0006] A fully automatic twelve-station self-adhesive coil winding machine includes a fixed machine base;

[0007] A first winding mechanism is disposed on the fixed base and used to clamp one end of the wire for winding; a feeding and cutting mechanism is disposed above the first winding mechanism and used to feed and cut the wire; a second winding mechanism is slidably mounted on the fixed base and is disposed opposite to the first winding mechanism, the first winding mechanism and the second winding mechanism are connected to form a winding gap for winding the wire; a transmission flipping mechanism is disposed on the fixed base and used to drive the first winding mechanism and the second winding mechanism to achieve synchronous rotation of the first winding mechanism and the second winding mechanism; an anti-bulging mechanism is lifted and disposed on the fixed base and is disposed corresponding to the winding gap; a feeding mechanism is disposed on one side of the second winding mechanism and used to feed the coil after winding.

[0008] By adopting the above technical solution, when using the above fully automatic winding machine, one end of the wire is fixed to the first winding mechanism by the feeding and cutting mechanism, and then the second winding mechanism is moved to connect with the first winding mechanism. Then, the two winding mechanisms are rotated by the transmission flipping mechanism, so that the wire is continuously wound in the winding gap. By setting the anti-bulging mechanism, the tension of the wire can be stabilized and the probability of the wire jumping or vibrating can be reduced.

[0009] Optionally, the first winding mechanism includes a first winding mold base, a first mounting shaft spaced apart from the first winding mold base, a rear mold fixing shaft fixed to the end of the first mounting shaft, and a clamping assembly disposed on the rear mold fixing shaft and used for clamping the wire.

[0010] The first mounting shaft has a rear mold drive wheel at one end away from the rear mold fixing shaft, and the transmission flipping mechanism has a rear mold drive wheel corresponding to the rear mold drive wheel. The rear mold drive wheel and the rear mold drive wheel are connected in a transmission manner.

[0011] By adopting the above technical solution, the structural composition of the first winding mechanism is disclosed. The first winding mold base provides an installation base for each component. The rear mold fixed shaft facilitates the setting of clamping components to clamp the wire. The rear mold transmission wheel is connected to the rear mold drive wheel of the transmission flipping mechanism, which enables the transmission flipping mechanism to drive the first winding mechanism to rotate, thereby realizing the winding function.

[0012] Optionally, the clamping assembly includes a clamping bracket fixed to the rear mold fixing shaft, a clamping shaft disposed on the clamping bracket, two sets of clamping claws rotatably mounted on the clamping shaft, a clamping elastic element connecting the two sets of clamping claws, and an unlocking element for driving the clamping claws to relax, wherein the clamping elastic element drives the clamping claws to have a tendency to always move closer to each other.

[0013] By adopting the above technical solution, the clamping component can effectively and firmly clamp the wire, laying a good foundation for subsequent winding work. At the same time, the clamping claws can be easily released through the unlocking component, making it easy to remove the wound coil and improving the overall efficiency of the winding work.

[0014] Optionally, the feeding and cutting mechanism includes a feeding and cutting bracket, a wire-laying assembly corresponding to the rear mold fixed shaft, a feeding connecting rod for mounting the wire-laying assembly, and a feeding moving module disposed on the feeding and cutting bracket and driving the feeding connecting rod to rise, fall, or slide.

[0015] The wire-laying assembly includes a wire guide block fixed to the feeding connecting rod, a wire puller fixed to the wire guide block for guiding the wire, and a cutting component disposed on the wire guide block for cutting the wire.

[0016] By adopting the above technical solution, automatic feeding and cutting of wires can be achieved, avoiding the inefficiency of manual operation and improving winding efficiency. At the same time, the wire guide baffle can accurately guide the wire direction and ensure winding accuracy.

[0017] Optionally, the second winding mechanism includes a second winding die base slidably mounted on a fixed base, a rotating base rotatably mounted on the second winding die base, a second mounting shaft spaced apart from the rotating base, and a front die fixing shaft fixed to the second mounting shaft;

[0018] The second mounting shaft has a front mold drive wheel at one end away from the front mold fixing shaft, and the transmission flipping mechanism has a front mold drive wheel corresponding to the front mold drive wheel. The front mold drive wheel and the front mold drive wheel are connected in a drive connection.

[0019] By adopting the above technical solution, the second winding mechanism slides back and forth on the fixed base, and can drive the front mold fixed shaft of the second winding mechanism to rotate through the transmission flipping mechanism, thereby working in coordination with the first winding mechanism, effectively improving the automation level and winding efficiency of winding.

[0020] Optionally, the front mold fixing shaft includes a fixed mold rod connected to the second mounting shaft and a front mold housing sleeved on the fixed mold rod. The end of the rear mold fixing shaft is provided with a positioning slot for the fixed mold rod to be inserted. The front mold fixing shaft and the rear mold fixing shaft form the winding gap.

[0021] By adopting the above technical solution, the insertion and matching of the fixed mold rod and the rear mold fixed shaft precisely forms the winding gap, which enables the front mold fixed shaft and the rear mold fixed shaft to rotate synchronously, facilitating the orderly winding of the wire in the gap.

[0022] Optionally, the transmission flipping mechanism includes a transmission drive component, a rear mold rotating shaft connected to the output end of the transmission drive component, a flexible coupling disposed at one end of the rear mold rotating shaft, a front mold rotating shaft disposed on the rotating seat and used to connect the flexible coupling, and a flipping drive component for driving the rotating seat to rotate.

[0023] The rear mold drive wheel is located at the other end of the rear mold rotating shaft, and the front mold drive wheel is located at the other end of the front mold rotating shaft away from the flexible coupling. The end of the flexible coupling is provided with a connection socket that is inserted and engaged with the front mold rotating shaft.

[0024] By adopting the above technical solution, the transmission drive and the flipping drive are used to drive the rear mold rotating shaft and the rotating seat to rotate respectively. Then, the rear mold rotating shaft and the front mold rotating shaft are connected by a flexible coupling, which can ensure that the first winding mechanism and the second winding mechanism rotate synchronously, thereby improving the consistency and stability of winding.

[0025] Optionally, the anti-bulging mechanism includes an anti-bulging frame, a lifting bracket mounted on the anti-bulging frame, and a pressure wheel rotatably mounted on the lifting bracket and corresponding to the winding gap. A buffer is provided between the bottom of the pressure wheel and the lifting bracket.

[0026] By adopting the above technical solution, pressure can be applied to the wire at the winding gap by the pressure roller during the winding process to avoid winding bulge. At the same time, the buffer can prevent excessive pressure from damaging the wire, so that the pressure roller always abuts the wire.

[0027] Optionally, the unloading mechanism includes an unloading lifting plate that is lifted and mounted on the fixed base, an unloading clamping member that is slidably mounted on the unloading lifting plate, and an unloading conveyor belt that is disposed on the fixed base and used for conveying products.

[0028] By adopting the above technical solution, automatic feeding operation can be realized. The coil that has been wound can be transferred to the feeding conveyor belt by the lifting of the feeding lifting plate and the sliding of the feeding clamp. This achieves efficient product transportation and improves the overall working efficiency of the winding machine.

[0029] Optionally, a temperature control structure is also included, which includes a first air pipe disposed on the anti-bulging mechanism and a second air pipe disposed on the feeding and cutting mechanism. The first air pipe is connected to heating gas, and the second air pipe is connected to cold gas.

[0030] By adopting the above technical solution, the first and second air pipes of the temperature control structure are used to transport gas to relevant parts. The first air pipe is used to heat the wire, which can reduce the hardness of the wire and improve the forming efficiency. The second air pipe is used to cool the wire after forming to achieve rapid product shaping.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] This application achieves automatic winding of coils by setting up a first winding mechanism, a feeding and cutting mechanism, a second winding mechanism, a transmission and flipping mechanism, an anti-bulging mechanism, and a feeding mechanism, thereby reducing manual intervention and improving winding efficiency.

[0033] This application achieves the docking of the first winding mechanism and the second winding mechanism through a transmission flipping mechanism, and the two sets of winding mechanisms form a winding gap and rotate synchronously, which can efficiently carry out wire winding and arrangement.

[0034] The wire feeding and cutting mechanism enables the feeding and cutting of wires, making the winding process smoother and improving overall winding efficiency. Attached Figure Description

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0051] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0052] This application discloses a fully automatic twelve-station self-adhesive coil winding machine.

[0053] Reference Figure 1 A fully automatic twelve-station self-adhesive coil winding machine includes a fixed base 1, a first winding mechanism 2, a feeding and cutting mechanism 3, a second winding mechanism 4, a transmission and flipping mechanism 5, an anti-bulging mechanism 6, a feeding mechanism 7, and a temperature control structure. The top of the fixed base 1 has a rectangular mounting surface. In this application, the length direction X, the width direction Y, and the height direction Z of the fixed base 1 are defined.

[0054] Reference Figure 2 The first winding mechanism 2 is fixedly installed on the top surface of the fixed base 1. The first winding mechanism 2 includes a first winding mold base 21, a first mounting shaft 22 spaced apart from the first winding mold base 21, a rear mold fixing shaft 23 fixed to the end of the first mounting shaft 22, and a clamping component 24 disposed on the rear mold fixing shaft 23 and used to clamp the wire. The clamping component 24 is used to clamp the starting end of the wire.

[0055] Reference Figure 2 , Figure 3 and Figure 4The first winding mold base 21 is a rectangular frame arranged along the X direction, and the first mounting shafts 22 are evenly spaced along the length of the first winding mold base 21. A drive shaft 221 is rotatably mounted inside the first mounting shaft 22, and a rear mold drive wheel 222 is provided at the end of the first mounting shaft 22 away from the rear mold fixing shaft 23. The rear mold drive wheel 222 and the drive shaft 221 are coaxially fixed. In this embodiment, the rear mold drive wheel 222 is a synchronous wheel in the prior art, and the transmission flipping mechanism 5 has a rear mold drive wheel 51 corresponding to the rear mold drive wheel 222. The rear mold drive wheel 51 is located on the side of the outermost rear mold drive wheel 222, and the rear mold drive wheel 51 and the rear mold drive wheel 222 are connected by a synchronous belt drive, that is, the synchronous rotation of several first mounting shafts 22 is realized by the transmission flipping mechanism 5. In this embodiment, twelve sets of first mounting shafts 22 are mounted on the first winding mold base 21.

[0056] The rear mold fixing shaft 23 has a fixing head 231 coaxially fixed at the end away from the rear mold drive wheel 222 for mounting the clamping assembly 24. The clamping assembly 24 includes a clamping fixing frame 241 fixed to the fixing head 231, a clamping shaft 242 clamped by the clamping fixing frame 241, a clamping claw 243 rotatably mounted on the clamping shaft 242, a clamping elastic member 244 connecting the two sets of clamping claws 243, and an unlocking member 245 for driving the clamping claws 243 to release.

[0057] Combination Figure 5 The clamping and fixing bracket 241 is bolted to the fixing shaft head 231, and the clamping shaft 242 is fixed to the fixing shaft head 231 along the radial direction of the rear mold fixing shaft 23. The two sets of clamping claws 243 have a scissor-type clamping structure. The clamping claws 243 have a clamping end for wire arrangement at the end away from the rear mold fixing shaft 23, and an unlocking end that cooperates with the unlocking component 245 at the other end. One set of clamping ends has a convex clamping block 2431, and the other set of clamping ends has a concave groove 2432 that cooperates with the convex clamping block 2431. The insertion action of the convex clamping block 2431 and the concave groove 2432 allows the wire to be three-dimensionally wrapped rather than fixed solely by planar friction, improving clamping stability. The end of the convex clamping block 2431 has an anti-detachment part 2434 that restricts wire detachment. The end of the fixing shaft head 231 also has a wire-locking groove 2312 corresponding to the clamping claws 243.

[0058] The clamping elastic element 244 is a tension spring, and the two sets of clamping claws 243 are provided with connecting posts for fixing the two ends of the clamping elastic element 244. Under the action of the tension spring, the two sets of clamping ends tend to move closer to each other, so as to clamp and fix the wire.

[0059] The unlocking component 245 is located at the unlocking end of the clamping claw 243 and is used to drive the two sets of clamping claws 243 to rotate in opposite directions along the clamping shaft 242. The unlocking component 245 includes an unlocking frame 2451, a push shaft 2452 fixed on the unlocking frame 2451, and a push driving component 2453 that pushes the unlocking frame 2451. A push sleeve 2454 is sleeved on the outside of the push shaft 2452, and the push sleeve 2454 and the push shaft 2452 are rotatably engaged. The push shaft and the clamping shaft 242 are arranged in parallel. The unlocking end of the clamping claw 243 has an abutment slope 2433 for the push sleeve 2454 to abut and push. The push driving component 2453 is a push cylinder, which is fixed to the top of the fixed base 1 by a bracket. The output end of the push driving component 2453 is fixed with a top mold push plate 2455. The top mold push plate 2455 has a through hole corresponding to the rear mold fixing shaft 23. The inner diameter of the through hole is larger than the outer diameter of the rear mold fixing shaft 23, so as to reduce the probability of interference between the top mold push plate 2455 and the rear mold fixing shaft 23. Multiple sets of unlocking components 245 are fixed on the top mold push plate 2455, so that the horizontal movement of multiple sets of unlocking components 245 can be realized simultaneously by a set of pushing cylinders.

[0060] Reference Figure 6 and Figure 7 The feeding and cutting mechanism 3 includes a feeding and cutting bracket 31, a wire-laying assembly 32 corresponding to the rear mold fixed shaft 23, a feeding connecting rod 33 for mounting the wire-laying assembly 32, and a feeding moving module 34 for driving the feeding connecting rod 33 to rise, fall, or slide.

[0061] The wire-laying assembly 32 is located above the rear die fixing shaft 23. It guides the wire from the drum to the clamping assembly 24 and cuts the wire after winding. The wire-laying assembly 32 includes a wire guide block 321 fixed to the feeding connecting rod 33, a wire pull baffle 322 fixed to the wire guide block 321, and a shearing member 323 disposed on the wire guide block 321. The wire guide block 321 also has two sets of guide rollers 3211 along the height direction to guide the wire feeding.

[0062] The drawbar baffle 322 is a vertically arranged rectangular plate with a guide groove 3221 for wire arrangement. The shearing component 323 includes a shearing drive component 3231 fixed to the lead block 321 and a shearing head 3232 disposed at the output end of the shearing drive component 3231. The shearing head 3232 has a shearing clearance groove 32321, and the inner wall of the shearing clearance groove 32321 has a shearing inclined surface 32322. The shearing drive component 3231 is a cylinder, and the shearing head 3232 is made of high-strength alloy material. To improve the stability of shearing, the drawbar baffle 322 also has a placement groove 3222 for the end of the shearing head 3232.

[0063] During the winding process, the wire is positioned within the shearing clearance groove 32321, reducing the probability of interference between the wire and the shearing bevel 32322. After the coil winding is completed, the shearing drive 3231 is activated, causing the shearing bevel 32322 to move towards the wire. Under the impact of a certain speed, the tip of the shearing clearance groove 32321 causes the wire to break. The lead block 321 is also equipped with a clamping rod 325 for clamping the wire. The clamping rod 325 is arranged parallel to the shearing head 3232 and is located on the side of the shearing head 3232 away from the guide groove 3221. In this embodiment, the clamping rod 325 is driven by a cylinder.

[0064] The feeding connecting rod 33 has a feeding moving plate 331 that is lifted and mounted on the feeding wire cutting bracket 31. The feeding moving module 34 includes a first linear module 341 that drives the feeding moving plate 331 to move up and down, and a second linear module 342 that drives the second linear module 342 to move horizontally. Both the first linear module 341 and the second linear module 342 are driven by motor screws in the prior art, therefore, the structure and principle of the module will not be described in detail in this application.

[0065] Reference Figure 8 and Figure 9 The second winding mechanism 4 includes a second winding mold base 41 slidably mounted on the fixed base 1, a rotating base 42 rotatably mounted on the second winding mold base 41, a second mounting shaft 43 spaced apart from the rotating base 42, and a front mold fixing shaft 44 fixing the second mounting shaft 43.

[0066] The second winding die holder 41 slides horizontally along the Y direction. A linear module that drives the second winding die holder 41 to move is provided on the fixed base 1. The linear module has the same structure as the feeding moving module 34 and is moved linearly by a motor screw.

[0067] The structure of the second mounting shaft 43 is the same as that of the first mounting shaft 22. The second mounting shaft 43 has a front mold drive wheel 431 at the end away from the front mold fixing shaft 44. The second mounting shaft 43 and the transmission flipping mechanism 5 are connected by a synchronous belt drive. The front mold fixing shaft 44 includes a fixed mold rod 441 coaxially connected to the second mounting shaft 43 and a front mold outer shell 442 sleeved on the outside of the fixed mold rod 441.

[0068] The fixed mold rod 441 has a fixed mold plug 4411 at its end, and the fixed shaft head 231 has a positioning slot 2311 at its end for partial insertion of the fixed mold plug 4411. Under the action of the linear module, the fixed mold rod 441 is inserted into the positioning slot 2311, creating a winding gap 45 between the end of the fixed shaft head 231 and the end of the front mold housing 442. In this embodiment, the fixed mold plug 4411 has a rectangular cross-section, therefore the final wound product is a rectangular hollow coil. In other embodiments, the fixed mold plug 4411 can be disassembled and assembled according to the shape of the actual product.

[0069] To facilitate product demolding from the fixed mold plug 4411, the front mold housing 442 is slidably mounted on the outside of the fixed mold rod 441. The front mold housing 442 has a sliding chamber 4421, and a demolding spring 4422 is provided in the sliding chamber 4421. The two ends of the demolding spring 4422 abut against the fixed mold plug 4411 and the front mold housing 442 respectively. When the product needs to be unloaded, the front mold housing 442 is driven to move towards the fixed shaft head 231, and the end of the front mold housing 442 can push the product to initially detach from the fixed mold plug 4411.

[0070] The transmission flipping mechanism 5 is located on the same side of the first winding mechanism 2 and the second winding mechanism 4. It is used to realize the synchronous rotation of the first winding mechanism 2 and the second winding mechanism 4, and at the same time realize the flipping of the second winding mechanism 4.

[0071] Reference Figure 10 and Figure 11 The transmission and flipping mechanism 5 includes a transmission drive 53, a rear mold rotation shaft 54, a flexible coupling 55, a front mold rotation shaft 56, and a flipping drive 57.

The synchronous pulley and the transmission drive component 53 are connected by belt drive. A flexible coupling 55 is fixed to the end of the rear mold shaft away from the rear mold drive wheel 51. The flexible coupling 55 is a diaphragm coupling of the prior art. Its end is provided with a connection socket 551, and the connection socket 551 has a connection slot 552 that penetrates the opposite sidewall.

[0073] The structure of the front mold rotating shaft 56 is the same as that of the rear mold rotating shaft 54, and the front mold drive wheel 52 is fixed to one end of the front mold rotating shaft 56. The other end of the front mold rotating shaft 56 is provided with a connecting clip 561 that is inserted into the connecting socket 551. Through the insertion and engagement of the connecting clip 561 and the connecting socket 551, the transmission connection of the two winding mechanisms is realized.

[0074] The flipping drive 57 is a servo motor fixed to the second winding die base 41, and its output end is fixed to one side of the rotating base 42. The flipping drive 57 enables the rotating base 42 to be flipped up and down, so as to adjust the front die fixing shaft 44 from the horizontal direction to the vertical direction. The second winding die base 41 is also equipped with a guide block 411 for rotating the guide connecting clip 561. The bottom of the guide block 411 has a guide groove 4111, and the guide block 411 is rotated by a rotary cylinder.

[0075] Reference Figure 12 The fixed base 1 has a lifting groove 11 between the first winding mechanism 2 and the second winding mechanism 4, and the anti-bulging mechanism 6 is installed on the bottom wall of the lifting groove 11. The anti-bulging mechanism 6 includes an anti-bulging frame 61, a lifting bracket 62 that is lifted and installed on the anti-bulging frame 61, and a pressure wheel 63 that is rotatably installed on the lifting bracket 62. The lifting bracket 62 is lifted and lowered by a cylinder, and the pressure wheel 63 has a wheel frame 631 that is slidably installed on the lifting bracket 62. A buffer 64 is provided between the bottom of the wheel frame 631 and the lifting bracket 62. The buffer 64 is a spring, and its two ends are fixed to the bottom of the wheel frame 631 and the lifting bracket 62 respectively, so that the pressure wheel 63 can always press the outside of the coil.

[0076] Reference Figure 13 The unloading mechanism 7 is located on the side of the second winding mechanism 4 away from the first winding mechanism 2. It includes an unloading lifting plate 71, unloading clamping members 72, and an unloading conveyor belt 73. The unloading lifting plate 71 is mounted on the fixed base 1 by a cylinder. An unloading translation plate 74 and a cylinder for driving the unloading translation plate 74 to move in the Y direction are mounted on the unloading lifting plate 71. The unloading clamping members 72 are spaced apart along the length of the unloading translation plate 74, and each unloading clamping member 72 corresponds to a front mold fixed shaft 44. The unloading clamping member 72 has two sets of oppositely arranged unloading claws 721, which are driven by clamping cylinders.

[0077] The unloading conveyor belt 73 is located between the unloading lifting plate 71 and the second winding mechanism 4, and it is a conventional belt conveyor structure. The unloading clamping member 72 clamps the product from the front mold fixing shaft 44 and places it on the unloading conveyor belt 73, which then transports the product to the next station.

[0078] Reference Figure 12 and Figure 14 To reduce wire stiffness and improve forming efficiency, this application also includes a temperature control structure. The temperature control structure includes a first air pipe 65 disposed on the lifting bracket 62 and a second air pipe 324 installed on the lead wire block 321. Both the first air pipe 65 and the second air pipe 324 are connected to a compressed air source. A heating tube 651 is sleeved on the outside of the first air pipe 65 so that the compressed gas blown out from the first air pipe 65 is used to heat the wire. The lead wire block 321 has guide air holes 3212 for the gas blown out from the second air pipe 324. The guide air holes 3212 correspond to the winding gap 45, and the guide air holes 3212 are arranged in an array.

[0079] The implementation principle of a fully automatic twelve-station self-adhesive coil winding machine according to an embodiment of this application is as follows: the clamping component 24 is moved to the lower part of the rear mold fixed shaft 23, the feeding moving module 34 moves the wire-laying component 32 down so that the wire on the wire-laying component 32 corresponds to the clamping component 24, and pushes the fixed mold push plate so that a gap for wire insertion is formed between the two sets of clamps, and at the same time the wire is inserted into the wire-locking groove 2312 of the fixed shaft head 231;

[0080] The wire assembly 32 rises and resets, moves the second winding mold base 41, so that the connecting socket 551 and the connecting clip 561 are inserted and engaged, and at the same time the fixed mold rod 441 is inserted into the positioning slot 2311; the anti-bulging structure rises and the first air pipe 65 is activated, and the transmission drive 53 is activated, so that the front mold fixed shaft 44 and the rear mold fixed shaft 23 rotate synchronously, and the coil begins to be wound.

[0081] During the winding process, the wire-laying assembly 32 moves back and forth along the X direction, so that the wire is evenly wound back and forth in the winding gap 45. After the winding is completed, the shearing component 323 is activated to cut the wire, and at the same time, the second air pipe 324 is activated to initially cool the product. The second winding mechanism 4 is disconnected from the second winding mechanism 4, and the flipping drive component 57 is activated to adjust the front mold fixing shaft 44 to a vertical state. The lifting plate is pushed by the cylinder component to make the product initially separate from the fixed mold rod 441. Finally, the product is moved to the unloading conveyor belt 73 by the unloading clamping component 72.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
