Description

TECHNICAL FIELD

[0001] The present application relates to the field of production equipment, in particular to an assembling device and method of an inverter and a motor. BACKGROUND

[0002] In the manufacturing process of a compressor inverter, the inverter and the motor need to be assembled together, and the points to be assembled include: 1. The female terminal of the motor needs to be inserted together with the male terminal on the inverter; 2. The rotor of the motor needs to be inserted together with the shaft hole inside the inverter; 3. The plurality of insertion hole on the motor casing needs to be inserted together with the insertion pin on the inverter.

[0003] The inventor found that the difficulties of assembling the inverter and the motor are: 1. The female terminal of the motor is electrically connected with the stator of the motor through a flexible wire, and the connection between the female terminal and the motor body is only through the flexible wire, so the position of the female terminal when it is delivered is not fixed; 2. The end of the rotor of the motor is flat, and the shaft hole inside the inverter is provided with an inner rotating piece, the center of the inner rotating piece is provided with a flat hole, and the rotor of the motor needs to be inserted after aligning the angle with the flat hole of the inner rotating piece; 3. The above three assembly points have a sequence, and the assembly sequence is: female terminal and male terminal, rotor and shaft hole, and insertion pin and insertion hole, first, if the insertion hole and the insertion pin or the rotor and the shaft hole are assembled first, the motor casing will be connected with the inverter and assembled together, and the female terminal and the male terminal will lack the assembly space, so the female terminal and the male terminal must be assembled first, second, the assembly sequence of the rotor and the shaft hole and the insertion pin and the insertion hole is discussed, because the stator inside the motor has a strong magnetic force, so when the motor is delivered, the position of the rotor may be eccentric under the influence of the strong magnetic force, although the rotor is arranged in the motor casing through the bearing, but there is still a relatively large radial offset allowance between the rotor and the stator, so the position of the rotor when it is delivered is also uncertain, if the insertion pin and the insertion hole are assembled first, the rotor and the shaft hole may not be aligned when assembled and collide; 4. Because the assembly gap (i.e. assembly precision) of the insertion hole and the insertion pin is smaller than that of the rotor and the shaft hole, the insertion pin and the insertion hole may not be aligned when assembled.

[0028] Step S400, the inverter continues to be driven downward, the rotor synchronously moves downward to reset, and the inverter continues to move downward until the pin of the inverter is inserted into the pin hole of the motor.

[0029] The assembling device and method of the application have at least the following beneficial effects:

[0030] (1) The assembly equipment of the application first lifts the rotor of the motor and the female terminal upward to a predetermined height through the jacking device, then the rotor positioning device clamps and positions the position of the rotor, and then the female terminal is placed on the female terminal suction device. At this time, the positions of the female terminal and the rotor are fixed and clear. Then the jig assembly of the inverter assembly device is connected with the inverter, the shaft hole on the inverter is aligned with the rotor, and the male terminal on the inverter is aligned with the female terminal. Then the press-fitting assembly drives the jig assembly and the inverter to move downward together. In this process, the locking assembly locks the jig assembly so that it cannot float horizontally. With the descent of the inverter, the male terminal and the female terminal are inserted together, and the upper end of the rotor is inserted into the shaft hole of the inverter in advance. At this time, the rotor and the inverter complete the pre-assembly, the female terminal suction device releases the female terminal, and the rotor positioning device releases the rotor. The press-fitting assembly drives the inverter to continue to move downward, the jacking device drives the rotor to move downward synchronously and reset to the motor. Because the rotor is limited by the shaft hole of the inverter, even if the rotor is affected by the magnetic force of the stator inside the motor during the resetting process, it will not deviate greatly. When the rotor is reset to the original position and with the downward movement of the inverter, the rotor and the shaft hole are completely inserted together. The inverter continues to move downward, the latch on the inverter is aligned with and inserted into the latch hole of the motor. If the latch and the latch hole are not aligned, the locking assembly releases the jig assembly, and the jig assembly can float horizontally relative to the press-fitting assembly through the floating assembly, so that the latch horizontally floats to be aligned with the latch hole and inserted. The assembly equipment of the application solves many contradictions and difficulties in the assembly of the motor and the inverter through ingenious structural design, which can greatly improve the work efficiency.

[0031] (2) The assembly method of this application defines the assembly sequence of multiple assembly points. First, the male and female terminals are assembled, then the rotor is pre-assembled, and finally the positioning pins are assembled. After the motor arrives, the rotor and female terminals are first pushed out of the housing to avoid the rotor being affected by the magnetic force of the stator inside the housing, which would cause its position to be uncertain. After being lifted, the rotor is positioned, and then the female terminals are placed in the selected position to clarify the position of the rotor and female terminals. Since the position of the male terminal on the inverter is fixed, the inverter can be easily transferred to the top of the rotor using existing mechanical devices to align the inverter shaft hole with the rotor and the male terminal with the female terminal. During the downward assembly of the inverter, the male and female terminals are aligned. The rotor and the upper end of the rotor are inserted into the inverter's shaft hole, achieving pre-assembly of the rotor and shaft hole. This ensures that even if the rotor is affected by magnetic force during its downward reset back into the motor, it will not shift. As the inverter moves downward, the rotor resets to its original position and is inserted into the inverter's shaft hole. Then, the pins on the inverter are inserted into the pin holes of the motor. At this point, all three assembly points are complete. The assembly method of this application optimizes the assembly sequence of the assembly points and adopts a pre-assembly method where the rotor is pushed out of the housing. This avoids the problem of the rotor being unable to be assembled due to uncertain position caused by the stator's magnetic force. The assembly method of this application provides a new approach to the assembly of motors and inverters. Attached Figure Description

[0062] The features and exemplary embodiments of various aspects of the present application will be described in detail below with reference to the drawings. The following detailed description is merely intended to explain the present application, and is not intended to limit the present application. The present application can be implemented without some of the specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0064] Example 1:

[0065] like Figure 1 As shown, this embodiment discloses an assembly device for an inverter and a motor, which is used to assemble an inverter 600 and a motor 500 together.

[0066] like Figure 1 As shown, in order to facilitate understanding of the technical solution of this embodiment, the following directions are defined first: the horizontal direction is defined as the X-axis direction, the horizontal direction is defined as the Y-axis direction, and the height direction is defined as the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction intersect each other perpendicularly to form a three-dimensional rectangular coordinate system.

[0067] The inverter 600 and motor 500 required for assembly in this embodiment are both existing structures, which will be briefly introduced below.

[0068] like Figure 2 and Figure 3 As shown, the inverter 600 has multiple pins 610 on its lower surface. In this embodiment, there are three pins 610. The inverter 600 has a shaft hole 600a extending along the Z-axis, and an inner rotating plate 620 is provided inside the inverter 600. The center of the inner rotating plate 620 has a flat hole, which forms part of the shaft hole 600a. Therefore, if the rotor 530 of the motor 500 is to be inserted into the shaft hole 600a, the rotor 530 of the motor 500 needs to be designed with a flat part 5321 that matches the flat hole. The flat part 5321 needs to be aligned with the angle of the flat hole before it can be inserted. A male terminal 630 is provided on the lower side of the inverter 600. The male terminal 630 extends downward along the Z-axis and is fixed to the housing of the inverter 600. Its position relative to the housing of the inverter 600 is fixed.

[0069] like Figure 4 and Figure 5As shown, the motor 500 includes a casing 510, a stator 520, a rotor 530, and a female terminal 540, the casing 510, the stator 520, and the rotor 530 are sequentially sleeved and connected, the upper surface of the casing 510 is provided with a plug hole 510a corresponding to the plug 610 of the inverter 600; the rotor 530 is installed in the inside of the casing 510 through a bearing 550, the female terminal 540 is electrically connected with the stator 520 through a flexible cable, when the motor 500 is delivered, the female terminal 540 is placed at the upper end of the rotor 530, and since the female terminal 540 is only electrically connected with the stator 520 through the flexible cable, the position of the female terminal 540 when delivered is uncertain. Further, the rotor 530 includes a rotating body 531 and a shaft body 532, the rotating body 531 is coaxially sleeved on the outer circumference of the shaft body 532, the lower end of the shaft body 532 extends downward to the lower end of the rotating body 531 along the Z-axis direction, and the lower end of the shaft body 532 is rotatably connected in the casing 510 through the bearing 550, the lower end surface of the shaft body 532 is provided with an anti-rotation pin 560, and the upper end of the shaft body 532 is provided with a flat part 5321, when assembling, the upper end of the shaft body 532 needs to be inserted into the shaft hole 600a of the inverter 600.

[0070] The motor 500 and the inverter 600 of the embodiment need to be assembled at three points, which are that the male terminal 630 and the female terminal 540 need to be plugged together, the rotor 530 and the shaft hole 600a need to be plugged together, and the plug 610 and the plug hole 510a need to be plugged together.

[0071] The assembly equipment of the embodiment includes a jacking device 100, a rotor positioning device 200, a female terminal adsorption device 300, and an inverter assembly device 400, which are specifically as follows:

[0072] As shown in Figure 6 The jacking device 100 is arranged below the wire body 700, the wire body 700 is arranged along the X-axis direction, the wire body 700 is provided with a tray 710, the tray 710 is provided with the motor 500 to be assembled, and the jacking device 100 is used to jack up the rotor 530 and the female terminal 540 of the motor 500 along the Z-axis direction.

[0073] As shown in Figure 6 and Figure 7As shown, the lifting device 100 includes a first base 110, a lifting mechanism 120, and a lifting column 130. The first base 110 is located below the line 700, and the lifting mechanism 120 is located on the first base 110. The lifting mechanism 120 is configured as an existing linear actuator such as a telescopic cylinder, and the lifting direction of the lifting mechanism 120 is configured as the Z-axis direction. The lifting column 130 is coaxially connected to the telescopic end of the lifting mechanism 120. The upper end of the lifting column 130 is provided with a circular rotor limiting groove 130a. The inner diameter of the rotor limiting groove 130a is slightly larger than the outer diameter of the rotor 530 (specifically the shaft 532 of the rotor). Here, "slightly larger" can be 1.01 to 1.2 times. The inner bottom surface of the rotor limiting groove 130a is provided with a downwardly recessed anti-rotation groove 130b, and the lower end of the shaft 532 of the rotor 530 is provided with an anti-rotation pin 560, which can be inserted downward into the anti-rotation groove 130b.

[0074] In this embodiment, when the rotor 530 needs to be lifted, the lifting mechanism 120 drives the lifting column 130 to move upward and pass through the tray 710, lifting the rotor 530 inside the motor 500 upward along the Z-axis. Since the upper end of the lifting column 130 is provided with a rotor limiting groove 130a, and since the shaft 532 of the rotor 530 protrudes downward relative to the rotating body 531, the shaft 532 of the rotor 530 can be inserted into the rotor limiting groove 130a during the upward movement of the lifting column 130. The rotor limiting groove 130a can prevent the rotor 530 from undergoing a large radial offset during the lifting process. On the other hand, during the lifting process of the lifting column 130, the anti-rotation pin 560 at the lower end of the rotor 530 is inserted into the anti-rotation groove 130b to restrict the rotation of the rotor 530, preventing the rotor 530 from not being able to assemble with the shaft hole 600a of the inverter 600 after the angle of the rotor 530 changes.

[0075] like Figure 6 As shown, in this preferred embodiment, the lifting device 100 further includes a pallet top plate 140 and a pallet lifting cylinder (not labeled). The pallet top plate 140 is slidably disposed on the first base 110 along the Z-axis direction, and the pallet top plate 140 is located on the upper side of the first base 110. The pallet lifting cylinder is disposed on the first base 110, and the telescopic end of the pallet lifting cylinder is connected to the pallet top plate 140. The telescopic direction of the pallet lifting cylinder is configured to be the Z-axis direction. When the motor 500 receives material, the pallet top plate 140 moves upward to lift the pallet 710 on the line 700 and remove it from the line 700.

[0076] like Figure 8As shown, the rotor positioning device 200 includes two clamping assemblies 210, which are respectively arranged on the two sides of the first seat body 110 along the Y-axis direction and are respectively located on the two sides of the line body 700. The two clamping assemblies 210 can relatively approach or move away along the Y-axis direction. When the rotor 530 is jacked to a predetermined height, the two clamping assemblies 210 relatively approach along the Y-axis direction and clamp the rotor 530, so that the position of the rotor 530 is clear and fixed.

[0077] As shown in Figure 9 and Figure 11 As shown, the clamping assembly 210 includes a second seat body 211, a first sliding rail 212, an action plate 213, and a clamping plate 214. The second seat body 211 is arranged on one side of the first seat body 110 in the Y-axis direction. The first sliding rail 212 is arranged on the upper surface of the second seat body 211, and the length direction of the first sliding rail 212 is configured as the Y-axis direction. The action plate 213 is slidingly connected to the first sliding rail 212, and the sliding direction of the action plate 213 is configured as the Y-axis direction. The clamping plate 214 is horizontally arranged at the front end of the action plate 213, and a V-shaped notch 214a is arranged on the clamping plate 214. The V-shaped notch 214a has a V-shaped top view shape. When it is necessary to clamp the rotor 530, the action plates 213 of the two clamping assemblies 210 relatively approach in the Y-axis direction through the first sliding rails 212, so that the two clamping plates 214 relatively approach. The inner side wall of the V-shaped notch 214a can be in contact with the outer circumference of the rotor 530 (specifically the shaft body 532), and the V-shaped notch 214a has a guiding and centering function, so that the position of the rotor 530 can be corrected, so that the position of the rotor 530 is fixed and clear.

[0078] In this embodiment, the two V-shaped notches 214a can jointly form a positioning hole arranged on the outer circumference of the rotor 530. The position of the rotor 530 is limited by the positioning hole, so as to ensure that the rotor 530 can be aligned and inserted into the shaft hole 600a of the inverter 600.

[0079] As shown in Figure 8 In this embodiment, two clamping assemblies 210 are arranged, which are respectively referred to as a first clamping assembly 210a and a second clamping assembly 210b. The structure of the first sliding rail 212 of the first clamping assembly 210a and the first sliding rail 212 of the second clamping assembly 210b can be the same or different. In this embodiment, the first sliding rail 212 of the first clamping assembly 210a is preferably a sliding rail with driving capability, which can autonomously drive the action plate 213 and the clamping plate 214 to move in the Y-axis direction under the control of an external system. The first sliding rail 212 of the second clamping assembly 210b is a sliding rail without driving capability, which only serves as a sliding connection. The action plate 213 and the clamping plate 214 of the second clamping assembly 210b can be manually pushed by a worker to slide in the Y-axis direction.

[0080] As shown in Figure 9 The second clamping assembly 210b of the embodiment further comprises a first manual clamp 215, a fixed end of the first manual clamp 215 being connected with the second seat body 211, and a moving end of the first manual clamp 215 being hinged with the action plate 213. When the worker needs to push the action plate 213 to slide, the worker can manually hold the operation handle of the first manual clamp 215 to push the action plate 213 to move along the Y-axis direction until the V-shaped notch 214a on the clamping plate 214 is enclosed on the outer periphery of the rotor 530, and then the operation handle of the first manual clamp 215 is pushed to the locking direction to lock the positions of the action plate 213 and the clamping plate 214.

[0081] In the embodiment, at least one of the two clamping assemblies 210 is designed to be manually operated, which can save cost and reduce complexity, and fully utilize the on-site manpower.

[0082] As shown in Figure 9 The second clamping assembly 210b of the embodiment further comprises a telescopic reset member 216, two ends of the telescopic reset member 216 being connected with the second seat body 211 and the action plate 213 respectively, and a telescopic direction of the telescopic reset member 216 being configured as the Y-axis direction. In the embodiment, the telescopic reset member 216 is configured as a spring. In the embodiment, the telescopic reset member 216 can be provided to realize automatic reset of the action plate 213 after unlocking, so that the clamping plate 214 is automatically released and away from the rotor 530.

[0083] As shown in Figure 10 In some preferred embodiments, the rotor positioning device 200 further comprises two elbow clamp assemblies 220, the two elbow clamp assemblies 220 being respectively arranged at two ends of the first clamping assembly 210a along the X-axis direction, specifically, the two elbow clamp assemblies 220 being respectively arranged at two ends of the second seat body 211, and the two elbow clamp assemblies 220 being located at the lower side of the action plate 213. The two elbow clamp assemblies 220 are symmetrically arranged about the Y-axis direction, and are used to clamp the outer periphery of the rotor 530. When the rotor 530 is lifted upward, the two elbow clamp assemblies 220 clamp the outer periphery of the rotor 530 from both sides of the X-axis direction, and then the two clamping assemblies 210 of the rotor positioning device 200 clamp the rotor 530. In the embodiment, the rotor 530 is clamped twice, which can realize two-stage correction of the position of the rotor 530. The first-stage correction is realized by the two elbow clamp assemblies 220, and the two-stage correction is realized by the centering function of the V-shaped notch 214a.

[0084] As shown in Figure 10As shown, the elbow clamp assembly 220 includes a second sliding rail 221 connected to the horizontal side of the second seat body 211, and the length direction of the second sliding rail 221 is configured as the Y-axis direction, and an elbow clamp 222 connected to the second sliding rail 221, driven by the second sliding rail 221 to move towards and away from the rotor 530 in the Y-axis direction, and the second sliding rail 221 is preferably a sliding rail with driving capability; the elbow clamp 222 is configured as an elbow clamp cylinder in the prior art, which can swing and clamp the rotor 530.

[0085] When the elbow clamp assembly 220 of the embodiment needs to clamp the rotor 530, the second sliding rail 221 drives the elbow clamp 222 to move to the horizontal side of the rotor 530, and then the elbow clamp 222 swings to contact the rotor 530, so that the two elbow clamps 222 can clamp the rotor 530 from both sides.

[0086] As shown, Figure 11 The female terminal suction device 300 is provided on the rotor positioning device 200, which can be provided on the second seat body 211, the action plate 213, or the clamp plate 214, and is preferably provided on the action plate 213 of the second clamping assembly 210b in the embodiment, and is used to provide a mounting and connecting position for the female terminal 540 to fix and clarify the position of the female terminal 540.

[0087] As shown, Figure 11As shown, the female terminal suction device 300 of the embodiment includes a positioning block 310 arranged on the action plate 213 of the second clamping assembly 210b, the positioning block 310 is provided with a downwardly recessed profiling groove 310a, the inner peripheral shape of the profiling groove 310a matches the outer peripheral shape of the female terminal 540, and the position of the female terminal 540 is limited through the profiling groove 310a. Wherein, the positioning block 310 can be tightly connected with the female terminal 540, further ensuring the position stability of the female terminal 540, the tightly connected mode includes: the positioning block 310 itself has magnetism (such as an electromagnet), the female terminal 540 can be adsorbed through the magnetic adsorption mode, or the inner bottom surface of the profiling groove 310a of the positioning block 310 is provided with one or more negative pressure adsorption holes 310b, the negative pressure adsorption holes 310b are communicated with the external negative pressure equipment, and the female terminal 540 is tightly adsorbed in the profiling groove 310a through the negative pressure generated by the negative pressure adsorption holes 310b. In the embodiment, when the motor 500 is delivered, the female terminal 540 is generally placed on the upper end of the rotor 530, so when the rotor 530 is jacked up, the female terminal 540 is also jacked up to a predetermined height, and then the female terminal 540 can be placed in the profiling groove 310a through the external mechanical hand or artificial, and in the embodiment, considering the complexity of the structure, cost, installation space and other factors, therefore, in the embodiment, the female terminal 540 is placed in the profiling groove 310a by artificial, and the first manual clamp 215 can be operated by artificial, and the human power is fully utilized.

[0088] As shown in Figure 12 The inverter assembly device 400 includes a press assembly 410, a floating assembly 420, a jig assembly 430 and a locking assembly 440, and the details are as follows:

[0089] As shown in Figure 12 The press assembly 410 is used to drive the floating assembly 420, the jig assembly 430 and the locking assembly 440 to move in the Z-axis direction. The press assembly 410 includes a first mounting plate 411 and a servo press 412; when the inverter 600 and the motor 500 are assembled, the inverter 600 is located directly above the jacking device 100 and the motor 500, further, the first mounting plate 411 can be directly fixed and installed above the jacking device 100, and the first mounting plate 411 can also be installed on the external mechanical device and driven by the external mechanical device to move to the position above the jacking device 100; the servo press 412 is arranged on the first mounting plate 411, the output end of the servo press 412 is connected with the floating assembly 420, and the downward pressing direction of the servo press 412 is configured as the Z-axis direction.

[0090] As shown in Figure 1As shown, the assembling device of the embodiment further comprises an X-axis module 450 and a Z-axis module 460; the X-axis module 450 is located above the second seat body 211 of the rotor positioning device 200 and extends along the X-axis direction; the Z-axis module 460 is connected to the X-axis module 450, and the X-axis module 450 is used to drive the Z-axis module 460 to move in the X-axis direction; the first mounting plate 411 of the press-fitting assembly 410 is connected to the Z-axis module 460, and the first mounting plate 411 can be driven to move in the Z-axis direction through the Z-axis module 460. In the embodiment, the entire inverter assembling device 400 can be driven to move in the X-axis direction and the Z-axis direction through the X-axis module 450 and the Z-axis module 460, which facilitates the material taking and transferring of the inverter 600 to be assembled. In addition, in some other embodiments, a six-axis manipulator can be directly designed to drive the inverter assembling device 400 to move in the three-dimensional space, and the six-axis manipulator is connected to the first mounting plate 411.

[0091] As shown in Figure 12 and Figure 13 , the floating assembly 420 comprises a second mounting plate 421, elastic members 422 and floating balls 423; the second mounting plate 421 is arranged below the first mounting plate 411 along the Z-axis direction, and the servo press 412 of the press-fitting assembly 410 is connected to the second mounting plate 421; the two ends of the elastic members 422 are respectively connected to the lower surface of the second mounting plate 421 and the upper side of the jig assembly 430, and the elastic members 422 are preferably springs; the number of the elastic members 422 is multiple, and the multiple elastic members 422 are distributed between the second mounting plate 421 and the jig assembly 430, and the extension direction of the elastic members 422 is configured as the Z-axis direction; the floating balls 423 are movably arranged between the second mounting plate 421 and the jig assembly 430, and in the embodiment, the floating balls 423 are preferably movably arranged on the jig assembly 430, for example, the upper surface of the third mounting plate 431 of the jig assembly 430 is provided with a semispherical ball groove, the floating balls 423 are rollably arranged in the ball groove, and at least part of the floating balls 423 protrude outward from the ball groove, when the outer circumference of the floating balls 423 is in rolling contact with the lower surface of the second mounting plate 421, the jig assembly 430 can be floated relative to the second mounting plate 421 in the horizontal direction, and the horizontal direction here can be the X-axis direction or the Y-axis direction or any direction in the horizontal plane. The floating balls 423 of the embodiment are multiple, and the multiple floating balls 423 are uniformly arranged on the third mounting plate 431 of the jig assembly 430.

[0092] The working principle of the floating assembly 420 is that the jig assembly 430 is connected with the inverter 600 to be assembled, when the inverter 600 is downwardly assembled, the elastic member 422 can avoid the damage caused by the rigid contact of the assembly point in the assembly, and when the latch 610 on the inverter 600 is not aligned with the latch hole 510a of the motor 500, the latch 610 can be abutted on the upper surface of the shell 510 of the motor 500, so that the elastic member 422 is compressed, at this time, the jig assembly 430 can be horizontally pushed by hand or a mechanical hand, so that the jig assembly 430 and the inverter 600 to be assembled are slightly floated in the horizontal direction, when the inverter 600 is horizontally floated to the position that the latch 610 is aligned with the latch hole 510a, the elastic potential energy of the elastic member 422 is instantaneously released and pushes the latch 610 of the inverter 600 to be downwardly inserted into the latch hole 510a, it needs to be explained here that when the inverter 600 is horizontally floated to the position that the latch 610 is aligned with the latch hole 510a, if the Z-axis module 460 or the servo press 412 releases the constraint of the inverter 600 in the Z-axis direction (that is, the Z-axis module 460 or the servo press 412 is in the unconstrained state), under the action of gravity, the latch 610 on the inverter 600 can also be inserted into the latch hole 510a, but such a way is obviously more complicated.

[0093] As Figure 12 And Figure 13As shown, the jig assembly 430 comprises a third mounting plate 431, a center column 432, a supporting plate 433, a positioning pin 434 and a clamping piece 435; in the Z-axis direction, the third mounting plate 431 is located below the second mounting plate 421, the upper end of the center column 432 (cylindrical) is fixedly connected with the second mounting plate 421, and the axial direction of the center column 432 is configured as the Z-axis direction; the center position of the third mounting plate 431 is provided with a center hole 431a, the center column 432 passes through the center hole 431a, and the center column 432 is in clearance fit with the center hole 431a; in this embodiment, preferably, the single-side clearance range of the center column 432 and the center hole 431a is 1mm to 5mm, of course, the specific range of the single-side clearance can be selected according to the actual situation, and the clearance fit between the center column 432 and the center hole 431a is to enable the third mounting plate 431 of the jig assembly 430 to rotate around the Z-axis and have a certain horizontal floating space; the supporting plate 433 is coaxially fixedly connected to the lower end of the center column 432, the upper surface of the supporting plate 433 is in contact with the lower surface of the third mounting plate 431, and the outer diameter of the supporting plate 433 is greater than the inner diameter of the center hole 431a, so that the third mounting plate 431 is supported in the Z-axis direction by the supporting plate 433; the upper end of the positioning pin 434 is fixedly arranged on the lower surface of the third mounting plate 431, the positioning pin 434 extends downward along the Z-axis direction, the inverter 600 to be assembled is provided with a mounting hole 600b, and the positioning pin 434 can be inserted downward into the mounting hole 600b, so as to realize the positioning between the third mounting plate 431 and the inverter 600 to be assembled; the number of the positioning pin 434 in this embodiment is multiple, and the multiple positioning pins 434 are arranged on the lower surface of the third mounting plate 431 in the Z-axis direction, and the inverter 600 to be assembled is provided with mounting holes 600b corresponding to the positioning pins 434 one by one; the clamping piece 435 is connected to the third mounting plate 431 and is used for clamping the inverter 600 to be assembled; the clamping piece 435 is specifically preferably a clamping air cylinder in the prior art; when the positioning pin 434 and the mounting hole 600b of the inverter 600 are inserted together, the clamping piece 435 clamps the inverter 600, so that the inverter 600 abuts against the lower side of the third mounting plate 431, thereby avoiding that the inverter 600 is separated from the third mounting plate 431; when the clamping piece 435 releases the inverter 600, the inverter 600 can be separated downward from the third mounting plate 431 under the action of its own gravity. In this embodiment, preferably, the number of the clamping pieces 435 is multiple, and the multiple clamping pieces 435 are arranged at intervals in the Z-axis direction.

[0094] The working principle of the jig assembly 430 is as follows: the jig assembly 430 is driven by the X-axis module 450 to move laterally along the X-axis direction to the material taking position 800, the inverter 600 to be assembled is placed at the material taking position 800, then the jig assembly 430 is driven by the Z-axis module 460 to move downward until the positioning pin 434 is inserted into the mounting hole 600b of the inverter 600, and then the clamping piece 435 clamps the inverter 600, thereby completing the material taking.

[0095] As shown in Figure 14 and Figure 15 In some preferred embodiments, the jig assembly 430 further comprises an angle positioning mechanism 470, which comprises a frame 471, a rotor shaft 472 and two second manual clamps 473. The rotor shaft 472 is shaped the same as the rotor 530, specifically a flat part 5321 is arranged on the rotor shaft 472 to limit the angle of the inner rotor 620 inside the inverter 600. The rotor shaft 472 is arranged on the frame 471, and the axial direction of the rotor shaft 472 is configured as the Z-axis direction. The two second manual clamps 473 are respectively connected to the two ends of the frame 471. The fixed end of the second manual clamp 473 is connected to the frame 471, and the pressing end of the second manual clamp 473 is used to press on the inverter 600 to be assembled. By inserting the rotor shaft 472 into the shaft hole 600a of the inverter 600 to be assembled, the inner rotor 620 inside the shaft hole 600a will not rotate during the transfer of the inverter 600 from the taking position 800 to the assembling position, thereby avoiding the angular misalignment between the shaft hole 600a and the rotor 530 of the motor 500. It should be noted that in general, the inner rotor 620 inside the shaft hole 600a will not rotate, but if the structure is shaken too much or subjected to a large external force, it may be angularly deflected.

[0096] As shown in Figure 12 The locking assembly 440 is arranged on the second mounting plate 421 of the floating assembly 420, and is used to connect with the third mounting plate 431 of the jig assembly 430 and limit the horizontal position of the third mounting plate 431. The locking assembly 440 can be an electromagnet (which attracts the third mounting plate 431 to limit its horizontal movement or floating) or the preferred structure in the present embodiment.

[0097] As shown in Figure 16 The locking assembly 440 of the present embodiment comprises a locking telescopic member 441. The locking telescopic member 441 is fixedly arranged on the second mounting plate 421, and the telescopic direction of the locking telescopic member 441 is configured as the Z-axis direction. The third mounting plate 431 is provided with a limiting hole 431b, and the telescopic end of the locking telescopic member 441 corresponds to the limiting hole 431b in the Z-axis direction. When it is necessary to lock the third mounting plate 431 of the jig assembly 430, the telescopic end of the locking telescopic member 441 is extended downward and inserted into the limiting hole 431b, thereby limiting the horizontal floating of the third mounting plate 431. When it is necessary to release the limitation, the telescopic end of the locking telescopic member 441 is withdrawn from the limiting hole 431b. The locking telescopic member 441 of the present embodiment is configured as a telescopic cylinder, an electric push rod, etc.

[0098] As Figure 17 shown, the embodiment also discloses an assembling method of the inverter and the motor, the assembling method uses the assembling equipment in embodiment one, and the assembling method comprises the following steps:

[0099] Step A100, the line body 700 transports the tray 710 and the motor 500 placed on the tray 710 to the top of the jacking device 100, the jacking column 130 of the jacking device 100 moves upward, the rotor limiting groove 130a above the jacking column 130 is inserted into the shaft body 532 of the rotor 530, and the anti-rotation pin 560 of the rotor 530 is inserted into the anti-rotation groove 130b of the jacking column 130, with the upward movement of the jacking column 130, the rotor 530, the bearing 550 for installing the rotor 530 and the female terminal 540 placed on the rotor 530 are jacked upward to a predetermined height, and the predetermined height is selected according to actual requirements;

[0100] After the rotor 530 and the female terminal 540 are jacked to the predetermined height, the jacking is stopped, the elbow clamp assembly 220 of the rotor positioning device 200 is extended, the elbow clamp 222 of the elbow clamp assembly 220 clamps the rotor 530, and the first position correction of the rotor 530 is realized; then the two clamping plates 214 of the clamping assembly 210 relatively approach along the Y-axis direction, the clamping plate 214 of the clamping assembly 210 clamps the rotor 530, and the second position correction of the rotor 530 is realized.

[0101] The female terminal 540 on the rotor 530 is placed on the female terminal adsorption device 300, and the female terminal adsorption device 300 adsorbs the female terminal 540, and in the embodiment, the female terminal 540 is preferably placed in the profiling groove 310a and adsorbed through the negative pressure adsorption hole 310b.

[0102] Step A200, the worker first places the inverter 600 to be assembled on an angle recognition station (not shown), performs angle recognition on the inner rotor plate 620 in the inverter 600, so that the angle of the flat hole at the center position of the inner rotor plate 620 is in a predetermined position, if the recognized angle is correct, the inverter 600 is placed on the material taking position 800, if the recognized angle is incorrect, the angle of the inner rotor plate 620 is corrected through the imitation rotor shaft 472 or other tools, and after the correction is completed, the inverter 600 is placed on the material taking position 800 again.

[0103] Then, the X-axis module 450 drives the jig assembly 430 to laterally move to the top of the material taking position 800, the Z-axis module 460 drives the jig assembly 430 to move downward, and the positioning pins 434 of the jig assembly 430 are correspondingly inserted into the mounting holes 600b of the inverter 600, after the positioning pins 434 are inserted, the clamping pieces 435 of the jig assembly 430 clamp the inverter 600, and the material taking of the inverter 600 is completed.

[0104] X-axis module 450 and Z-axis module 460 cooperate to move the inverter 600 to be assembled to the position directly above the rotor 530. Since the position of the rotor 530 is corrected and fixed, the position of the female terminal 540 is also clear. Therefore, after the inverter 600 moves to the position directly above the rotor 530 along the X-axis direction, the shaft hole 600a of the inverter 600 is aligned with the rotor 530, and the male terminal 630 on the inverter 600 is aligned with the female terminal 540. In this step A200, the inner rotating piece 620 inside the inverter 600 is prevented from rotating by the angle positioning mechanism 470 connected to the inverter 600, which is optional.

[0105] Step A300, first, the locking assembly 440 keeps the locking state of the jig assembly 430, so that the jig assembly 430 cannot float in the horizontal direction. Then, the servo press 412 drives the floating assembly 420 and the jig assembly 430 to move downward as a whole, and the male terminal 630 on the inverter 600 is inserted into the female terminal 540. During the insertion of the male terminal 630 and the female terminal 540, the upper end of the rotor 530 is also inserted into the shaft hole 600a of the inverter 600 (if the angle positioning mechanism 470 is installed on the inverter 600 to be assembled, it needs to be removed first). During the insertion of the male terminal 630 and the female terminal 540, the elastic member 422 of the floating assembly 420 is gradually pressed. After the insertion is completed, the rotor 530 and the female terminal 540 are released, as follows:

[0106] First, the female terminal suction device 300 releases the negative pressure or magnetic attraction state, and then releases the female terminal 540;

[0107] Second, the elbow clamp 222 of the elbow clamp assembly 220 releases the rotor 530 and resets along the Y-axis direction. The clamping plate 214 of the clamping assembly 210 also releases the rotor 530 and resets along the Y-axis direction;

[0108] In a further preferred embodiment, before the clamping plate 214 of the clamping assembly 210 releases the rotor 530, the servo press 412 first drives the second mounting plate 421 of the floating assembly 420 to retract upward by a certain stroke. The stroke size here is selected according to actual needs and can be 1cm to 5cm. The reason for retracting by a certain stroke is that the elastic element 422 of the floating assembly 420 is under pressure at this time, while the female terminal 540 is indirectly set on the action plate 213 of the clamping assembly 210. Due to the action of the elastic element 422, the male terminal 630 and the female terminal 540 are elastically pressed together. If it does not retract upward, the action plate 213 will need a large force to retract. Therefore, by retracting upward, the elastic element 422 restores a certain deformation, thereby reducing the indirect force of the elastic element 422 on the action plate 213, so that the action plate 213 can be easily reset.

[0109] In step A400, the servo press 412 continues to drive the floating assembly 420 and the fixture assembly 430 to move downward as a whole. During the downward extension of the servo press 412, the lifting device 100 also drives the rotor 530 to reset downward at the same rate. During this process, the relative position of the inverter 600 and the rotor 530 remains unchanged. When the rotor 530 is reset to its original position inside the housing 510, the rotor 530 and the shaft hole 600a of the inverter 600 move relative to each other in the Z-axis direction and are inserted together. After the rotor 530 and the inverter 600 are inserted into place, the servo press 412 continues to drive the inverter 600 to move downward until the pin 610 of the inverter 600 is inserted into the pin hole 510a of the motor 500. At this time, the assembly of the motor 500 and the inverter 600 is completed.

[0110] like Figure 18 As shown, in step A400, if the pin 610 of the inverter 600 is not aligned and inserted into the pin hole 510a, the lower end of the pin 610 will press against the upper surface of the housing 510. The pressure of the servo press 412 can be used to determine if the pin 610 is pressing against the upper surface of the housing 510. If the pin 610 is pressing against the upper surface of the housing 510, the elastic element 422 will gradually be compressed, and the lower surface of the second mounting plate 421 of the floating assembly 420 will contact the floating ball 423 on the third mounting plate 431 of the fixture assembly 430. At this time, the control... The locking assembly 440 releases the third mounting plate 431 of the fixture assembly 430. Then, the third mounting plate 431 is pushed by a robot or a human hand, causing the pin 610 to slide horizontally. When the pin 610 slides to align with the pin hole 510a, the elastic element 422 drives the third mounting plate 431, the inverter 600, and the pin 610 to move downwards, causing the pin 610 to be inserted into the pin hole 510a, thereby completing the installation of the inverter 600 and the motor 500. The clamping element 435 of the fixture assembly 430 releases the inverter 600 and resets upwards.

[0111] Embodiment Two

[0112] Embodiment Two discloses an assembling method of an inverter and a motor. The structure of the inverter 600 and the motor 500 in Embodiment Two is the same as that in Embodiment One, and the number of points to be assembled of the inverter 600 and the motor 500 is also the same as that in Embodiment One.

[0113] As shown in Figure 19 , the assembling method of Embodiment Two is different from that of Embodiment One in that the assembling method of Embodiment Two does not need to use the assembling equipment of Embodiment One.

[0114] The assembling method of Embodiment Two comprises:

[0115] Step S100, after the motor 500 is delivered, the rotor 530 and the female terminal 540 of the motor 500 are pushed out from the shell 510 along the Z-axis direction to a predetermined height by using existing mechanisms or mechanical hands and the like, then the rotor 530 is positioned so as to be stabilized, and then the female terminal 540 is placed at a selected position, the coordinates of which in space are known, and the selected position is selected according to the actual situation on site. The selected position and the female terminal 540 can be connected together by using electromagnetic adsorption, negative pressure adsorption, bonding or clamping and the like;

[0116] Step S200, the inverter 600 is transferred to the upper side of the rotor 530. Specifically, the inverter 600 can be transferred to the upper side of the rotor 530 by using existing mechanical hands or mechanical structures, or the inverter 600 can be directly installed on the upper side of the rotor 530. When the inverter 600 is located at the upper side of the rotor 530 or is directly installed on the upper side of the rotor 530, the position of the rotor 530 and the female terminal 540 is clear, so that the shaft hole 600a of the inverter 600 can be aligned with the rotor 530 up and down when the inverter 600 is transferred to the upper side of the rotor 530 or is directly installed on the upper side of the rotor 530, and the male terminal 630 on the inverter 600 is aligned with the female terminal 540 up and down;

[0117] Step S300, the existing mechanical hand or mechanical structure drives the inverter 600 along the Z-axis direction downward, so that the male terminal 630 and the female terminal 540 are inserted together. After the male terminal 630 and the female terminal 540 are inserted in place, the position (i.e. the selected position mentioned above) for placing the female terminal 540 is disconnected from the female terminal 540. During the insertion process of the male terminal 630 and the female terminal 540, the upper end of the rotor 530 is inserted into the shaft hole 600a of the inverter 600, so as to realize the pre-insertion of the rotor 530 and the shaft hole 600a.

[0118] In step S400, the inverter 600 continues to be driven downwards, and the rotor 530 moves downwards synchronously with the descent rate of the inverter 600 to perform a reset movement. After the rotor 530 resets to its original position inside the housing 510, the inverter 600 continues to be driven downwards, so that the rotor 530 is gradually inserted into the predetermined depth position of the shaft hole 600a. After the rotor 530 and the shaft hole 600a are inserted, the inverter 600 continues to be driven downwards until the pin 610 of the inverter 600 is inserted into the pin hole 510a of the motor 500, and the assembly of the inverter 600 and the motor 500 is completed.

[0119] like Figure 20 As shown, in step S400, preferably, if the pin 610 of the inverter 600 is not aligned with the pin hole 510a of the motor 500, the inverter 600 is slightly pushed and slid in the horizontal direction by an existing robotic arm or mechanical structure. When the pin 610 slides to be aligned with the pin hole 510a, the pin 610 is inserted into the pin hole 510a.
