Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, specifically relating to a winding machine for a high full-slot ratio stator and its winding method. Background Technology

[0002] Patent document CN202010786014.6 discloses a winding machine structure for an inner stator. This structure uses a hanging-wire method to wind the inner stator. During the winding process, the lead nozzle hangs the enameled wire sequentially on the upper and lower hook assemblies, and the upper and lower hook assemblies complete the winding in the stator slots. In this winding method, the lead nozzle does not need to enter the stator slots; the enameled wire is only hooked into the slots by the hook assemblies on the upper and lower parts of the stator. Therefore, this method can improve the slot fill factor of the inner stator, but the hanging-wire winding method has a significantly lower winding speed. Summary of the Invention

[0003] To improve the winding speed of a high slot fill factor stator, this invention provides a winding machine and winding method for a high slot fill factor stator.

[0004] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0005] The present invention provides a high full-slot ratio stator winding machine, including a stator mounting assembly and a wire hooking assembly; characterized in that: it further includes a winding assembly and a winding motion mechanism; the winding assembly is connected to the winding motion mechanism located on one side of the stator mounting assembly; the winding machine has a first winding position; the first winding position is: the winding assembly includes a wire guide nozzle, the wire guide nozzle protrudes into the tooth groove of the stator fixed on the stator mounting assembly, and the wire guide nozzle is eccentrically disposed with respect to the stator.

[0006] Preferably, the stator mounting assembly is capable of driving the stator to rotate axially.

[0007] Preferably, the winding motion mechanism includes a sixth motor and a seventh motor. The sixth motor can drive the winding assembly to move closer to or away from the stator and the hook assembly; the seventh motor can drive the winding assembly to move in an axial direction parallel to the stator.

[0008] Preferably, the winding motion mechanism further includes a ninth motor, which can drive the winding assembly to move in the same direction as the sixth motor.

[0009] Preferably, the sixth motor has a shorter drive stroke than the ninth motor, and the winding assembly is mounted on the third sliding mechanism driven by the sixth motor.

[0010] In another aspect, the present invention also provides a winding method for a winding machine for a high full-slot ratio stator, comprising: step one, adjusting the winding machine to a first winding position.

[0011] Preferably, the winding method further includes: Step 2, under the drive of the winding motion mechanism, the wire nozzle moves in the direction of the stator tooth groove, and in conjunction with the stator mounting assembly, drives the stator to swing and rotate, winding the enameled wire onto the iron core of the stator.

[0012] Preferably, step two further includes: the wire nozzle moving in the opposite direction to the tooth groove movement when the stator rotates.

[0013] Preferably, the winding method is a winding-then-hanging method.

[0014] Preferably, the winding method further includes: step three, adjusting the winding machine to the second winding position, wherein the second winding position is: the lead wire nozzle is parallel to the radial direction of the stator or along the radial direction; the first and second wire hanging mechanisms of the wire hook assembly are close to the stator and are in the same plane as the lead wire nozzle.

[0015] In a preferred embodiment of the present invention, in the first winding position, the wire nozzle forms an angle with respect to the iron core, such that the outlet end of the wire nozzle is biased to the outside of the wound iron core.

[0016] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: The winding machine of the present invention is suitable for winding inner stators. Structurally, the winding machine of the present invention is designed with a movable winding assembly based on the hanging-type winding machine. It can be used in conjunction with the hooking assembly for hanging-type winding, or the winding assembly can be used for independent winding. Compared with the hanging-type winding of the prior art, the lead nozzle of the present invention can enter the slots of the stator for winding, especially when producing inner stators with high slot fill factor, where winding can be performed before hanging; the winding speed of this winding method can be increased by up to 10 times. Inner stators with high slot fill factor have a large number of turns, and the slot spacing decreases as the number of winding turns increases. To adapt to the winding of inner stators with high slot fill factor, the present invention designs the relative position and angle between the lead nozzle and the iron core at the winding position, adopting an eccentric setting of the lead nozzle, so that the lead nozzle is offset towards the outside of the iron core when it is in the slot of the stator, expanding the movement space during winding and increasing the slot fill factor when using the winding assembly alone, which can reach 85%. Building upon this foundation, employing a hanging-type winding method further enhances the slot fill factor. This pre-winding followed by hanging-type winding not only achieves a high slot fill factor stator with single-hanging-type winding but also significantly improves production efficiency. Furthermore, by eccentrically designing the lead nozzle relative to the stator during winding, and coordinating with the rotation of the stator mounting assembly, the travel distance of the lead nozzle in the forward and backward directions is shortened, preventing collisions caused by forward and backward movement during winding. A short-stroke third sliding mechanism is used for left and right movement, enabling wire alignment during winding and preventing the enameled wire from piling up in the same position, which would affect the number of turns. This also reduces weight, prevents vibration caused by winding, and increases winding speed. Attached Figure Description

[0031] Example 1: Structure of a high-slot full-rate stator winding machine

[0032] The structure of the high full-slot ratio stator winding machine of the present invention is as follows: Figures 1-6As shown, the device includes a stator mounting assembly 1 and a wire hook assembly 2 for fixing the stator 101; it also includes a winding assembly 5 and a winding motion mechanism 6; the winding assembly 5 is connected to the winding motion mechanism 6 located behind the stator mounting assembly 1; the winding machine has a first winding position; the first winding position is as follows: the winding assembly 5 includes a wire guide nozzle 501, which inserts into the tooth groove 103 of the stator 101 fixed on the stator mounting assembly 1, and the wire guide nozzle 501 is eccentrically positioned with respect to the stator 101. A schematic diagram in a top view is shown below. Figure 7 As shown in (A) or 7(B). The direction of the lead nozzle 501 is parallel to the hook assembly 2, and the direction of the lead end is towards the hook assembly 2. In the embodiment of the present invention, the hook assembly 2 is on the left, so the direction of the lead nozzle 501 is horizontal to the left, which can be adapted to the hanging wire winding method. The stator winding machine of the present invention uses the winding assembly 5 instead of the hook assembly 2 to wind the coil, which has a higher winding speed. The lead nozzle 501 at the first winding position is eccentrically set with the stator 101, so that the lead nozzle 501 is deviated from the outside of the iron core 102 in the tooth groove 103 of the stator, which expands the movement space of the lead nozzle 501 during winding, and can increase the number of turns and slot fill factor when using the winding assembly 5 alone for winding; further improving the winding speed of the first winding and then hanging wire method.

[0033] The specific structure is as follows: The high-slot full-rate stator winding machine includes a stator mounting assembly 1, a wire hooking assembly 2, a first support frame 3, a worktable 4, a winding assembly 5, and a winding motion mechanism 6; Figure 2 As shown, the stator mounting assembly 1 is used to fix the stator 101; it drives the stator 101 to rotate along its axial direction. The reciprocating oscillation and rotation of the stator can coordinate with the movement of the hook assembly 2 and the winding assembly 5, thereby realizing the winding. The stator mounting assembly 1 has multiple wire hanging posts 104, which are used to hang the wire before starting to wind or to transition to the next iron core 102 after winding the wire through the toothed grooves 103 on both sides of one iron core 102. The stator 101 is an inner stator, which is surrounded by multiple iron cores 102, with toothed grooves 103 formed between the iron cores.

[0034] To the left of the stator mounting assembly 1 is the hook assembly 2; the hook assembly 2 is slidably connected to the first support frame 3 and can slide vertically on the first support frame 3. Above the stator mounting assembly 1 is the winding assembly 5; the winding assembly 5 is mounted on the winding motion mechanism 6 behind the stator mounting assembly 1 and can perform three-dimensional spatial movement. The winding assembly 5 can cooperate with the stator mounting assembly 1 and the hook assembly 2 to perform hanging-type winding motion, and can also directly wind the iron core 102 of the stator 101 in the toothed groove 103 of the stator 101.

[0035] like Figures 3-4As shown, the rightmost part of the hook assembly 2 consists of the first hook mechanism 201 and the second hook mechanism 204; the left side of the first hook mechanism 201 is connected to the first motor 202 via a reducer shaft; the first motor 202 is fixed to the left side of the first sliding mechanism 203, the first hook mechanism 201 is located to the right of the first sliding mechanism, and the shaft of the first motor 202 is parallel to the radial direction of the stator 101. The second wire-hanging mechanism 204 is connected to the second motor 205 via a reducer. The shaft of the second motor 205 is parallel to the first motor 202 and fixed to the left side of the second sliding mechanism 206. The second wire-hanging mechanism 204 is located on the right side of the second sliding mechanism. The right ends of the first wire-hanging mechanism 201 and the second wire-hanging mechanism 204 are hook-shaped and used to hook the enameled wire fed by the wire nozzle 501. The first motor 202 and the second motor 205 can drive the first wire-hanging mechanism 201 and the second wire-hanging mechanism 204 to rotate respectively, hook the enameled wire, and after rotation, the tension of the enameled wire causes it to slide off the first wire-hanging mechanism 201 or the second wire-hanging mechanism 204 to complete the winding.

[0036] The first sliding mechanism 203 is slidably connected to the right side of the first support frame 3. A third motor 207 is connected to the right side of the first sliding mechanism 203 via a lead screw, and the third motor 207 is fixed to the top of the first support frame 3 via a motor mount. The second sliding mechanism 206 is slidably connected to the right side of the first support frame 3. A fourth motor 208 is connected to the right side of the second sliding mechanism 206 via a lead screw, and the fourth motor 208 is fixed to the top of the first support frame 3 via a motor mount. The third motor 207 and the fourth motor 208 can respectively drive the first sliding mechanism 203 and the second sliding mechanism 206 to slide on the first support frame 3. The sliding directions of the first sliding mechanism 203 and the second sliding mechanism 206 are parallel and both vertical, moving up and down to hang the wire.

[0037] In this embodiment, the projected shape of the right side of the first support frame 3 is as follows: Figure 4 As shown, the first support frame 3 is U-shaped and vertical. The first motor 202 and the second motor 205 are located in the middle of the U-shape. The front and rear of the U-shape of the first support frame 3 are slidably connected to the first sliding mechanism 203 and the second sliding mechanism 206, respectively. The bottom of the first support frame 3 is slidably connected to the worktable 4. A pair of parallel fifth motors 401 are fixed on the worktable 4 by motor mounts. The fifth motors 401 are connected to the bottom of the first support frame 3 by lead screws. The axis of the fifth motors 401 is parallel to that of the first motor 202, which can drive the first support frame 3 to slide left and right. This allows the first support frame 3 and the hook assembly 2 connected to the first support frame 3 to move closer to or away from the stator mounting assembly 1, and also enables wire arrangement during hanging-type winding.

[0038] Above the stator mounting assembly 1 is the winding assembly 5, which is connected to the winding motion mechanism 6 on the rear side of the stator mounting assembly 1. The winding motion mechanism 6 drives the winding assembly 5 to achieve multi-axis movement. This causes the winding assembly 5 to move around the iron core 102 of the stator 101, winding the enameled wire into the toothed grooves 103. Specifically... Figures 5-6 As shown, the winding assembly 5 includes a wire guide nozzle 501 and a positioning shaft 503; the direction of the positioning shaft 503 is parallel to the axial direction of the stator 101; the wire guide nozzle 501 is a guide nozzle for enameled wire, with the left end being the wire outlet end; the wire guide nozzle 501 is rotatably connected to the positioning shaft 503 via a fixing pin 502, the fixing pin 502 being perpendicular to the positioning shaft 503; a cylinder 504 is connected to the wire guide nozzle 501, the cylinder 504 being able to drive the wire guide nozzle 501 to rotate around the fixing pin 502, thereby being parallel to the axial direction of the first motor 202 and cooperating with the first wire hanging mechanism 201 to hang the wire; or the direction of the second wire hanging mechanism 204 can be rotated to a direction parallel to the positioning shaft 503 to achieve wire passage.

[0039] The positioning shaft 503 is fixed on the winding motion mechanism 6. The winding motion mechanism 6 drives the positioning shaft 503 and the wire nozzle 501 connected to the positioning shaft 503 to perform three-dimensional motion. The winding motion mechanism 6 includes a third sliding mechanism 601, a fourth sliding mechanism 602, a sixth motor 603, a second support frame 604, a seventh motor 605, a fifth sliding mechanism 606, and an eighth motor 607.

[0040] The positioning shaft 503 of the winding assembly 5 is fixed on the third sliding mechanism 601, which is slidably connected to the fourth sliding mechanism 602. A sixth motor 603 is fixed to the front of the fourth sliding mechanism 602 via a motor mount. The sixth motor 603 is connected to the third sliding mechanism 601 via a lead screw. The axis of the sixth motor 603 is parallel to the fifth motor 401, enabling the third sliding mechanism 601 to slide left and right on the fourth sliding mechanism 602, thereby causing the winding assembly 5, including the positioning shaft 503 and the lead nozzle 501, to move left and right. The sixth motor 603 is a short-stroke motor in the winding motion mechanism 6, used to drive the lead nozzle 501 to deliver the enameled wire to the first hanging mechanism 201 and the second hanging mechanism 204, and also to realize wire arrangement during winding. The third sliding mechanism 601 is slidably connected to the second support frame 604. The top of the second support frame 604 is fixed with the seventh motor 605. The seventh motor 605 is connected to the fourth sliding mechanism 602 through a lead screw. The axis of the seventh motor 605 is parallel to the positioning shaft 503, which can drive the fourth sliding mechanism 602 to slide up and down on the second support frame 604, thereby driving the winding assembly 5 to move up and down to achieve wire passing.

[0041] The bottom of the second support frame 604 is slidably connected to the fifth sliding mechanism 606. An eighth motor 607 is fixed on the fifth sliding mechanism 606. The eighth motor 607 is connected to the second support frame 604 through a lead screw. The axis of the eighth motor 607 is perpendicular to the sixth motor 603 and the seventh motor 605, and can drive the second support frame 604 to move back and forth. The fifth sliding mechanism 606 is slidably connected to the worktable 4. The worktable 4 is equipped with a ninth motor 402. The axis of the ninth motor 402 is parallel to the sixth motor 603, and can drive the fifth sliding mechanism 606 and the second support frame 604 to slide left and right. The sliding stroke of the fifth sliding mechanism 606 is greater than that of the third sliding mechanism 601. The eighth motor 607 and the ninth motor 402 drive the support frame to move in a plane. The plane of motion is parallel to the stator 101, thereby driving the wire nozzle 501 to complete a large left and right movement, such as the winding action at the beginning of winding.

[0042] In this embodiment, the first sliding mechanism 203, the second sliding mechanism 206, the third sliding mechanism 601, the fourth sliding mechanism 602, the fifth sliding mechanism 606, the first support frame 3, and the second support frame 604 are all sliding components, and the corresponding sliding connection method is a linear guide rail, which can be one or more parallel linear guide rails.

[0043] In this embodiment, the winding motion mechanism 6 is a three-axis motion mechanism, including two motors for left and right movement: a short-stroke sixth motor 603 and a long-stroke ninth motor 402. These motors primarily move the positioning shaft 503 and the guide nozzle 501 in a direction parallel to the axis of the first motor 202. This direction is essentially radial or parallel to the stator 102, used to move the winding assembly 5 closer to or further away from the stator 101 and the hook assembly 2. It also moves the guide nozzle 501 closer to or further away from the stator 101, the first hook mechanism 201, and the second hook mechanism 204, thereby completing a series of winding actions. The ninth motor 402 moves the guide nozzle 501 to / from the winding position, including hooking the wire onto the hook post 104 or winding the wire end. The guide nozzle 501 moves into the tooth groove 103 of the stator 101, etc. The sixth motor 603 is smaller in size and lighter in weight, and is used for more repetitive actions, including hanging the enameled wire on the first wire-hanging mechanism 201 and the second wire-hanging mechanism 204, and realizing wire arrangement when winding in the toothed groove 103. This structure is more sensitive to movement and can effectively solve the vibration problem during high-speed wire hanging and winding, thus achieving a higher winding speed. The winding speed of the winding machine of this invention is 10 times that of existing wire-hanging winding machines, greatly reducing the production time of the stator. As the winding motion mechanism 6, a cam structure can also be adopted, in which the rotation of the stator 101 causes the iron core 102 to move back and forth, and the winding assembly 5 only moves left and right and up and down.

[0044] Example 2: Winding method for the structure of Example 1

[0045] The structure shown in Example 1 can realize the following three winding methods, and the specific steps are as follows.

[0046] 1. Method 1: Wire winding

[0047] Step 1, winding preparation: Fix the stator 101 on the stator mounting assembly 1, with the wire nozzle 501 parallel to the positioning shaft 503. The eighth motor 607 and the ninth motor 402 of the winding motion mechanism 6 drive the wire nozzle 501 to wind the wire end on the hanging post 104 of the stator mounting assembly 1; adjust the winding machine to the first winding position.

[0048] First winding position: When the seventh motor 605 drives the guide nozzle 501 to enter the tooth groove 103 of the stator 101, the guide nozzle 501 is eccentrically positioned with respect to the stator 101. At this time, the guide nozzle 501 is in a winding state and rotates to be perpendicular to the positioning shaft 503. This winding position is as follows: Figure 7 As shown in any one of the embodiments, the lead nozzle 501 is parallel to the radial direction of the stator, and its eccentric arrangement forms an angle with respect to the iron core 102. This angle causes the lead outlet end of the lead nozzle 501 to be offset to the outside of the central axis of the iron core 102 being wound. The angle of the lead nozzle 501 is such that the lead outlet end of the lead nozzle 501 is as far away from the iron core 102 as possible, providing a larger winding space during winding and thus improving the slot fill factor of the winding type.

[0049] Step 2, Winding: Driven by the fourth motor 208 and the eighth motor 607 in the winding mechanism 6, the wire nozzle 501 moves up and down within the tooth groove 103 along the direction of the tooth groove 103. Combined with the stator mounting assembly 1 driving the stator to oscillate and rotate, the enameled wire is wound onto the stator core 102. During winding, the wire nozzle 501 moves in the opposite direction to the tooth groove movement as the stator rotates. Specifically, when the enameled wire is wound one turn, the movements of the wire nozzle 501 and the stator mounting assembly 1 are as follows: the wire nozzle 501 moves forward while the stator mounting assembly 1 rotates clockwise, causing the tooth groove 103 to move backward; the wire nozzle 501 moves downward; the wire nozzle 501 moves backward while the stator mounting assembly 1 rotates counterclockwise, causing the next tooth groove 103 to move forward; the wire nozzle 501 moves upward. The wire nozzle 501 moves up and down to wind the enameled wire into the tooth groove 103. In conjunction with the left and right movement of the sixth motor 603 with a short stroke, the wire can be laid out to prevent the enameled wire from piling up in the same position.

[0050] In another preferred embodiment of the present invention, the lead nozzle 501 only moves up and down, the stator mounting assembly 1 swings and rotates to complete the winding, and the left and right movement of the lead nozzle 501 completes the wiring.

[0051] Step 3, Wire Passing: After the wire nozzle 501 is rotated to be parallel to the positioning shaft 503, it moves upward. The stator mounting assembly 1 rotates to rotate the next iron core 102 to the first winding position, and then the operation of step 2 is repeated.

[0052] In Method 1 of this embodiment, the wire guide nozzle 501 is used to wind the wire in the tooth groove 103 of the stator 101. Compared with the prior art, the movement of a single turn of winding is decomposed into forward and backward and up and down directions. Therefore, when the wire guide nozzle 501 is close to the left end of the stator 101, it is easy to collide with the edge of the stator 101. Based on this, the present invention adopts an eccentric design for the position of the wire guide nozzle 501, and uses the movement of the wire guide nozzle 501 of the winding assembly 5 to cooperate with the rotation of the stator mounting assembly 1 to avoid the wire guide nozzle 501 colliding with the stator 101 during winding.

[0053] Using the winding method of Method 1, a single strand of 0.8mm enameled wire is wound with a core thickness of 55mm at a winding speed of 150rpm; the number of turns reaches 170~200.

[0054] 2. Method Two: Hanging Wire Winding

[0055] Step 1, winding preparation: Fix the stator 101 on the stator mounting assembly 1, with the lead wire nozzle 501 parallel to the positioning shaft 503. The eighth motor 607 and the ninth motor 402 of the winding motion mechanism 6 drive the lead wire nozzle 501 to wind the wire end on the hanging post 104 of the stator mounting assembly 1; adjust the winding machine to the second winding position.

[0056] Second winding position: The seventh motor 605 drives the wire guide nozzle 501 to be located inside the stator 101 and along the radial direction of the stator 101; the fifth motor 401 drives the first support frame 3, causing the wire hook assembly 2 to move closer to the stator, so that the first wire hanging mechanism 201 and the second wire hanging mechanism 204 move above and below the stator 101, respectively, and are in the same plane as the wire guide nozzle 501. At this time, the wire guide nozzle 501 is in a winding state, rotated to a position perpendicular to the positioning shaft 503, and the direction of the wire guide nozzle 501 can also be parallel to the radial direction of the stator.

[0057] Step 2, Winding: When the enameled wire is wound one turn, the movement of the guide nozzle 501, the hook assembly 2, and the stator mounting assembly 1 includes: the guide nozzle 501 aligns with the first hanging mechanism 201 above; the sixth motor 603 drives the third sliding mechanism 601 to slide to the left, causing the guide nozzle 501 to enter the hook of the first hanging mechanism 201; the first hanging mechanism 201 rotates and hooks the enameled wire guiding the guide nozzle 501; the guide nozzle 501 moves to the right and exits the first hanging mechanism 201; the stator mounting assembly 1 rotates clockwise, and the first hanging mechanism 201... 1. Moving downwards or remaining stationary, the wire nozzle 501 moves downwards to align with the second wire-hanging mechanism 204 and then moves to the left, hanging the enameled wire on the second wire-hanging mechanism 204. The wire nozzle 501 then moves to the right to exit the second wire-hanging mechanism 204, and the stator mounting assembly 1 rotates counterclockwise. Simultaneously, the first wire-hanging mechanism 201 rotates, causing the enameled wire to fall off. 2. Moving upwards, the wire nozzle 501 hangs the enameled wire on the first wire-hanging mechanism 201 and then exits. The stator mounting assembly 1 rotates clockwise, and simultaneously, the second wire-hanging mechanism 204 below rotates. Under tension, the enameled wire winds onto the stator 101. This process of hanging wire on the first wire-hanging mechanism 201 and the second wire-hanging mechanism 204 is repeated to complete the winding of enameled wire within the toothed grooves 103 on both sides of the stator core 102. During the winding process, the fifth motor 401 drives the first support frame 3, which in turn moves the hook assembly 2 left and right to achieve wire arrangement.

[0058] Step 3, Wire Passing: After the wire nozzle 501 is rotated to be parallel to the positioning shaft 503, it moves upward. The stator mounting assembly 1 rotates to rotate the next iron core 102 to the second winding position, and then the wire hanging operation is repeated.

[0059] 3. Method Three: First winding the wire, then hanging the wire

[0060] Step 1, winding preparation: Same as step 1 of method 1.

[0061] Step 2, winding: Wind the wire according to Step 2 of Method 1.

[0062] Step 3: Before the normal winding process rubs against the adjacent coil, switch from winding to hanging winding and adjust the winding machine to the second winding position. Wind the remaining turns according to Step 2 of Method 2. After completion, pass the wire through the coil and repeat the winding method for the second core 102. The last core 102 can be wound using Step 2 of Method 2.

[0063] Step 4, wire feeding: After the wire guide nozzle 501 is rotated to be parallel to the positioning shaft 503, it moves upward. The stator mounting assembly 1 rotates to rotate the next tooth groove 103 to the first winding position, and then the operation of steps 2 and 3 is repeated.

[0064] It should be noted that in Method 3, the first iron core 102 can be wound using Method 1. Starting with the second iron core 102, a winding-then-hanging method is used initially. The switch from winding to hanging methods is generally performed when the slot fill factor reaches 85%, but it can also be less than 85%.

[0065] The winding method of Method 3 is used to wind a single strand of 0.8mm enameled wire with a core stack thickness of 55mm and a winding speed of 150rpm. The hanging wire winding speed is 20rpm and the number of turns is 200. After winding 170 turns, the winding method is switched to the hanging wire method.

[0066] In this embodiment, three winding methods are provided, and the winding direction of the enameled wire can also be reversed, corresponding to the opposite movement directions of each structure when the enameled wire is wound one turn. Furthermore, the order of single-turn winding is not limited to the above; any method that can complete the winding of a single-turn coil is acceptable.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed by the present invention.
