Abstract

The invention belongs to the technical field of motors, and specifically relates to a brushless motor manufacturing automation device, which comprises a base, a stamping main machine, and a stamping cutting component. The stamping cutting component comprises a mounting frame, a knife disc, and a stamping cutting knife. The stamping cutting end of the stamping cutting knife consists of a cutting blade and a stamping surface. By designing the stamping cutting end of the stamping cutting knife to consist of a cutting blade and a stamping surface, the cutting blade is used to cut a required stator core shape on a core raw material, and separate the cut stator core from the core raw material. The function of the stamping surface is to stamp out a concave area at the cutting edge of the cut stator core. Such a design can ensure that there is a gap between the cutting positions of two layers of stator cores that are fixed on an assembly component from top to bottom and are adjacent to each other, rather than direct contact. It is prevented that the two layers of stator cores adjacent to each other are connected in series at the cutting position, thereby affecting the normal operation of the stator core.

Description

Technical Field

[0001] The invention belongs to the technical field of motors, and in particular relates to automated equipment for manufacturing brushless motors. Background Art

[0002] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronics product. Since the brushless DC motor is operated in an automatic manner, it does not require an additional starting winding on the rotor like a synchronous motor that starts under heavy load under variable frequency speed regulation, nor does it produce oscillation and loss of step when the load changes suddenly.

[0003] During the manufacturing process of brushless motors, a stator core of a special shape needs to be produced. The existing production method is to manufacture the iron plate by stamping and cutting, but it cannot be assembled directly after stamping and cutting. If assembled directly, the conductive iron cores will contact and conduct electricity, and the iron core cannot achieve the function of increasing the magnetic field. Before assembly, the surface and cuts of the iron cores need to be insulated one by one, and the entire production process has more steps and a longer manufacturing time.

[0004] The present invention designs a brushless motor manufacturing automation equipment to solve the above problems. Summary of the invention

[0005] Based on this, it is necessary to provide a brushless motor manufacturing automation equipment to address the problems existing in the current brushless motor manufacturing stator core. The stamping cutting end of the stamping cutting knife is designed to consist of a cutting blade and a stamping surface. The cutting blade is used to cut the required stator core shape on the core material and separate the cut stator core from the core material; the function of the stamping surface is to punch out a concave area at the cutting edge of the cut stator core. This design can ensure that there is a gap between the cutting points of the two layers of stator cores that are fixed on the assembly component from top to bottom and are adjacent to each other, rather than direct contact; and prevent the two layers of stator cores that are adjacent to each other from being connected in series at the cutting point, thereby affecting the normal operation of the stator core.

[0068] like Figure 1 -like Fig.23 As shown, a brushless motor manufacturing automation equipment, such as Figure 1As shown, it includes a base 2, fixed on a workbench, for mounting a punching main machine 1; the punching main machine 1, fixedly mounted on the upper side of the base 2, for mounting a punching mounting rod 3 and a punching cutting assembly 4, on which a power assembly 1001 capable of controlling the punching mounting rod 3 to slide up and down is mounted; the punching mounting rod 3, slidably mounted on the punching main machine 1, can slide up and down relative to the punching main machine 1 and the base 2; Figure 3 , 4 As shown, the stamping and cutting assembly 4 is fixedly mounted on the lower end of the stamping mounting rod 3, and is used for stamping and cutting to form the stator core of the brushless motor stator; the stamping and cutting assembly 4 includes a mounting frame 5001 fixedly mounted on the lower end of the stamping mounting rod 3, a knife disc 4003 fixedly mounted on the lower side of the mounting frame 5001, and a stamping and cutting knife 4004 fixedly mounted on the lower side of the knife disc 4003; the stamping and cutting end of the stamping and cutting knife 4004 is composed of a cutting blade 4005 and a stamping surface 4006, and the cutting blade 4005 is used to cut the required stator core shape on the core raw material to separate the cut stator core from the core raw material; the function of the stamping surface 4006 is to stamp out a concave area at the cutting edge of the cut stator core; as shown Fig.15 , 16 As shown, the assembly component 9 is detachably installed in the base 2; it is used to collect and assemble the stator cores after punching and cutting; so that the stator cores cut by the punching and cutting component 4 are fixed and collected one by one from top to bottom.

[0069] The base 2, the stamping main machine 1 and the stamping installation rod 3 in the present invention belong to the prior art. The stamping main machine 1 is installed with a power assembly 1001 and a control module 1002 that can drive the stamping installation rod 3 to slide up and down.

[0070] In the present invention, the stamping installation rod 3 is controlled to slide downward, and the mounting frame 5001 can move downward, and the mounting frame 5001 drives the cutter disc 4003 to move downward, and the downward movement of the cutter disc 4003 drives the stamping cutting knife 4004 to move downward.

[0071] In the existing processing technology of the stator core of the brushless motor, the stator core material is soaked before stamping and cutting to form an insulating coating on its surface; however, during the stamping and cutting process, a new surface without an insulating coating will appear on the cutting surface, so that during the subsequent assembly, the cutting surfaces of the upper and lower adjacent layers of the stator core may directly contact each other to form a series connection, affecting the normal operation of the stator core after assembly; in order to prevent this from happening, the stamping and cutting end of the stamping cutting knife 4004 designed by the present invention is composed of a cutting blade 4005 and a stamping surface 4006, wherein the cutting blade 4005 is used to cut the required stator core shape on the core material and separate the cut stator core from the core material; the function of the stamping surface 4006 is to stamp out a concave area at the cutting edge of the cut stator core, such as Fig.21 As shown, such a design can ensure that there is a gap between the two layers of stator cores fixed on the assembly component 9 from top to bottom and adjacent to each other, rather than direct contact, and prevent the two layers of stator cores adjacent to each other from being connected in series at the cutting point, thereby affecting the normal operation of the stator core.

[0072] In a further embodiment, Figure 3 , 4 As shown, the punching and cutting assembly 4 includes a knife holder 4001, a knife disc 4003 and a punching and cutting knife 4004, wherein the knife holder 4001 is fixedly mounted on the lower end of the punching mounting rod 3, the knife disc 4003 is detachably mounted on the lower side of the knife holder 4001 by bolts, and the punching and cutting knife 4004 is fixedly mounted on the lower side of the knife disc 4003. In the present invention, the knife disc 4003 can be removed relative to the knife holder 4001, so that the punching and cutting knife 4004 can be easily replaced and repaired.

[0073] In a further embodiment, Figure 1 As shown, the stamping main machine 1 is composed of a horizontal table 102 and a vertical pillar 101 installed on the upper side of the horizontal table 102, and the horizontal table 102 is fixedly installed on the upper side of the base 2; the power component 1001 that controls the stamping mounting rod 3 to slide up and down and the control module 1002 are installed on the vertical pillar 101.

[0074] like Figure 1 As shown in , , 2, and 8, the upper side of the horizontal platform 102 is symmetrically provided with four guide sliding holes; the outer side of the tool holder 4001 is fixedly provided with four guide sliding rods 4002, and the four guide sliding rods 4002 correspond to the four guide sliding holes one by one and slide in cooperation. The cooperation between the four guide sliding rods 4002 and the four guide sliding holes can guide the punching and cutting of the punching and cutting knife 4004.

[0075] In a further embodiment, Figure 1 As shown, a square cavity 2001 is opened on the base 2.

[0076] like Figure 8 As shown, the upper side of the horizontal platform 102 is provided with a mounting slot 1023. Figure 5 , 8 As shown in Figures 9, a guide channel 1022 is opened downward in the middle of the installation slide groove 1023. The guide channel 1022 passes through the horizontal platform 102 downward and extends downward to the square cavity 2001 of the base 2. Two first installation grooves 1021 are symmetrically opened at the bottom of the installation slide groove 1023.

[0077] like Figure 5 , 6 As shown, a bottom support assembly 6 is installed on the upper side of the transverse platform 102 .

[0078] like Figure 6 , 7 As shown, the bottom support assembly 6 includes a support plate 6001, a first gear 6002, a first motor 6003 and a tooth plate 6004, wherein the tooth plate 6004 is fixedly installed on the bottom of the support plate 6001, and the two support plates 6001 are symmetrically slidably installed in the installation groove 1023 and are located on the upper side of the guide channel 1022; the two first motors 6003 are fixedly installed in the two first installation grooves 1021, and a first gear 6002 is fixedly installed on the output shaft of the two first motors 6003 respectively, and the two first gears 6002 correspond to the two tooth plates 6004 installed on the bottom of the two support plates 6001 one by one and mesh with each other.

[0079] During the punching and cutting process, the support plate 6001 in the bottom support assembly 6 supports the bottom of the stator core material being punched and cut. Fig.24 The support plate also has a lower groove 6006 that cooperates with the cutting blade, and the lower groove ensures that the stamping and cutting of the iron sheet is smoother; however, after stamping and cutting, in order to realize that the cut stator core can be directly collected and fixed to form a stator core group that can be wound with windings, the stator core that needs to be cut can fall down onto the assembly component 9 after stamping and cutting and be fixed and collected. In order to achieve this function, the two support plates 6001 need to slide to both sides after the stamping and cutting are completed, and the guide channel 1022 is opened to allow the cut stator core to fall; at this time, the two first motors 6003 need to be controlled to work, and the first motor 6003 works to drive the first gear 6002 to rotate, and the first gear 6002 rotates through the tooth plate 6004 to drive the two support plates 6001 to slide to both sides.

[0080] In a further embodiment, Figure 7 As shown, a U-shaped notch is provided on the support plate 6001 . When the two support plates 6001 are slid to the middle and closed together, the two U-shaped notches on the two support plates 6001 will merge into a square opening 6005 .

[0081] like Fig. 9 , 10 As shown in Figures 11, a guide column 7 is installed in the middle of the guide channel 1022, and multiple electric rods 10 are divided into upper and lower layers and fixedly installed in the guide channel 1022. The telescopic ends of the electric rods 10 are inserted into the guide columns 7 to limit the guide columns 7; the upper ends of the guide columns 7 pass through the square opening 6005 between the two support plates 6001 and are flush with the upper end surfaces of the support plates 6001.

[0082] like Figure 3 , 4As shown, the stamping cutter 4004 is divided into two parts, an inner cutter 4008 and an outer cutter 4007 . The cutting contour of the outer cutter 4007 is the same as the outer contour of the stator core; the cutting contour of the inner cutter 4008 is square, which is the same as the outer contour of the guide column 7 .

[0083] The function of the guide column 7 is to guide the stator core after it is cut. When the stator core is cut by punching, the punching cutter 4004 will not be lifted immediately. At this time, the two support plates 6001 will be controlled to slide to both sides to open the guide channel 1022. During this process, the punching cutter 4004 will limit the stator core after it is cut to prevent the stator core from being dislocated due to the force of the support plate 6001. When the guide channel 1022 is fully opened, the square hole in the middle of the stator core cut by the inner cutter 4008 will be sleeved on the guide column 7 and slide down along the guide column 7. During this process, the square hole and the guide column 7 are in close contact and sliding cooperation. During the process, when the stator core falls onto the first layer of electric rods 10, the first layer of electric rods 10 shortens to make way for the stator core to make way for the guide channel 1022. At this time, the guide column 7 is limited and supported by the lower layer of electric rods 10. When the stator core slides over the first layer of electric rods 10, the first layer of electric rods 10 extend to continue to limit and support the guide column 7. When the stator core slides onto the second layer of electric rods 10, the second layer of electric rods 10 shortens. In this process, the first layer of electric rods 10 supports the guide column 7. When the stator core slides over the second layer of electric rods 10, the second layer of electric rods 10 extend to continue to limit and support the guide column 7. The reason for designing the guide column 7 is that during stamping and cutting, the upper end of the guide column 7 is in close contact with the cut stator core, and there is a certain gap between the guide channel 1022 and the cut stator core due to the existence of the support plate 6001. When the stator core falls, it may be misaligned with the guide channel 1022, but because it is in close contact with the guide column 7, the possibility of misalignment is relatively small. Therefore, the guide column 7 is specially designed while designing the guide channel 1022.

[0084] In a further embodiment, Figure 3 , 9 As shown, the shape of the edge contour of the guide channel 1022 is the same as the outer contour shape of the stator core after cutting and forming. The stator core cut by stamping will fall into the guide channel 1022, slide downward under the guidance of the guide channel 1022, and fall on the assembly component 9 to be fixed and collected. The guide channel 1022 serves to guide the cut stator core. The outer surface of the stator core is in close contact with the inner wall of the guide channel 1022 during the falling process of the stator core.

[0085] In a further embodiment, Figure 1As shown, a mounting assembly 5 is installed in the square cavity 2001 opened in the base 2.

[0086] like Fig.13 As shown, the installation component 5 includes a mounting frame 5001 , a fixing groove 5003 is formed on the mounting frame 5001 , and the assembly component 9 is installed in the fixing groove 5003 .

[0087] In a further embodiment, Fig.15 , 16 As shown in FIG. 17 , the assembly component 9 includes a mounting column 9001, a keyway 9002, a stopper component 9003, and a bottom support plate 9004. Fig. 20 As shown, the mounting column 9001 is a square column, and four third mounting grooves 9010 are opened on the four outer wall surfaces of the mounting column 9001. A through circular hole is provided in the middle of the mounting column 9001, and a key groove 9002 is opened on the inner circular surface of the circular hole; four bottom support plates 9004 are fixedly installed evenly on the four outer wall surfaces at the bottom of the mounting column 9001 in the circumferential direction; and a plurality of limit assemblies 9003 are evenly installed in the four third mounting grooves 9010 from bottom to top.

[0088] like Fig.18 , 19 As shown, the limiting assembly 9003 includes a first limiting plate 9005, a volute spring 9006, a hinge shaft 9007, a second limiting plate 9008 and a leaf spring 9009, wherein the hinge shaft 9007 is rotatably installed in the corresponding third mounting groove 9010, and a volute spring 9006 is installed between the hinge shaft 9007 and the third mounting groove 9010; the first limiting plate 9005 is fixedly installed on the hinge shaft 9007, the second limiting plate 9008 is rotatably installed on the hinge shaft 9007, and a leaf spring 9009 is installed between the first limiting plate 9005 and the second limiting plate 9008; in the initial unpressurized state, the leaf spring 9009 can make the first limiting plate 9005 and the second limiting plate 9008 be distributed at an angle of 90 degrees, and the first limiting plate 9005 and the corresponding bottom support are arranged in parallel up and down.

[0089] In a further embodiment, Fig.14 , 15 As shown, the mounting frame 5001 is provided with two symmetrically distributed second mounting grooves 5002 , a second motor 8002 is fixedly mounted in each second mounting groove 5002 , and a shift plate 8001 is fixedly mounted on the output shaft of each second motor 8002 .

[0090] When the cut stator core slides down along the guide channel 1022 and the guide column 7 to the upper end of the mounting column 9001 on the assembly component 9, Fig. 22As shown in a in the figure, the stator core will first fall onto the first limiting plate 9005 in the uppermost limiting assembly 9003, because the first limiting plate 9005 is installed in the corresponding third mounting groove 9010 through the corresponding hinge shaft 9007, and a spiral spring 9006 is installed between the hinge shaft 9007 and the third mounting groove 9010, that is, the first limiting plate 9005 has a certain resistance when swinging downward, so the stator core falling on the first limiting plate 9005 will not continue to slide downward, and the side wall of the stator core contacts the corresponding second limiting plate 9008; at this time, the two second motors 8002 are controlled to work, and the second motors 8002 control the swing plate 8001 to swing, and the swing of the swing plate 8001 will squeeze the stator core downward, so that the stator core continues to slide downward, and the stator core moves to The downward sliding movement will squeeze the first limit plate 9005 on the lower side, and the first limit plate 9005 drives the corresponding second limit plate 9008 to swing through the corresponding leaf spring 9009. In the present invention, because the width between the two adjacent first limit plates 9005 is less than half the thickness of the stator core, the thickness of the first limit plate 9005 and the second limit plate 9008 are equal and both are less than half the thickness of the stator core, and the thickness of the stamped surface 4006 on the stator core after stamping is less than the thickness of the first limit plate 9005 and the second limit plate 9008; therefore, when the first limit plate 9005 just starts to swing downward, the side wall of the stator core is still in contact with the corresponding second limit plate 9008, and the corresponding second limit plate 9008 will first contact with the side wall of the stator core when being driven to swing. Fig. 22 As shown in b, at this time, the stator core limits the swing of the second limit plate 9008, and the leaf spring 9009 is compressed during this process; when the first limit plate 9005 is squeezed to a vertical state, the stator core and the second limit plate 9008 are also completely disengaged, as shown in FIG. Fig. 22 As shown in c in the figure, at this time, under the action of the leaf spring 9009, the second limit plate 9008 will swing towards the side close to the stator core, and finally swing to a state where it forms a 90-degree angle with the first limit plate 9005. When the stator core and the first limit plate 9005 are completely disengaged, as shown in FIG. Fig. 22 As shown in d in the figure, under the action of the spiral spring 9006, the corresponding first limit plate 9005 and the second limit will be reset; the stator core will gradually slide down from top to bottom, and when the stator core slides to the first limit plate 9005 in the bottom limit assembly 9003, the downward swinging plate 8001 will continue to squeeze the stator core downward, so that the stator core continues to slide downward, as shown in FIG. Fig.23As shown in a in the figure, the stator core slides downward and squeezes the first limit plate 9005 on the lower side. The first limit plate 9005 drives the corresponding second limit plate 9008 to swing through the corresponding leaf spring 9009. In the present invention, because the width between the two adjacent first limit plates 9005 is less than half the thickness of the stator core, the thickness of the first limit plate 9005 and the second limit plate 9008 are equal and both are less than half the thickness of the stator core; therefore, when the first limit plate 9005 just starts to swing downward, the side wall of the stator core is still in contact with the corresponding second limit plate 9008, and the corresponding second limit plate 9008 will first contact with the side wall of the stator core when being driven to swing, as shown in FIG. Fig.23 As shown in b in the figure, at this time, the stator core limits the swing of the second limit plate 9008, and the leaf spring 9009 is compressed in this process; when the first limit plate 9005 is squeezed to a vertical state, the stator core and the second limit plate 9008 are also completely disengaged. At this time, under the action of the leaf spring 9009, the second limit plate 9008 will swing toward the side close to the stator core, and finally swing to a state where it forms an angle of 90 degrees with the first limit plate 9005, clamping the stator core between the bottom support plate 9004 and the second limit plate 9008 of the lowest layer, and being fixed by the bottom support plate 9004 and the second limit plate 9008 of the lowest layer; as shown in FIG. Fig.23 As shown in c, when the second stator core falls, it will be clamped and fixed by the second limiting plate 9008 in the second limiting assembly 9003 and the second limiting plate 9008 in the third limiting assembly 9003; they are fixed in sequence; when the second limiting plate 9008 in the uppermost limiting assembly 9003 also swings to a horizontal state, the stator core on the assembly assembly 9 is assembled. At this time, the assembly assembly 9 and the stator core fixed thereon are removed, and subsequent immersion and coating of insulating material are carried out to ensure that the cutting surface on the electronic core is also coated with insulating material.

[0091] The first limiting plate 9005, the second limiting plate 9008, the leaf spring 9009, the spiral spring 9006 and the hinge shaft 9007 of the present invention are all made of insulating materials.
