Description

Technical Field

[0001] This invention belongs to the field of wire piercing technology, specifically relating to a stator wire piercing device for a series-wound motor. Background Technology

[0002] Piercing and crimping involves piercing the cable's insulation layer and crimping it to the wire core. Its key advantage is that it eliminates the need for stripping the insulation and allows for simultaneous termination of multiple wires. While this method is used for piercing and crimping the stator leads of a series-wound motor, current methods require workers to hold the stator leads to maintain their position. This excessive manual intervention reduces the automation level of stator lead piercing and crimping. Furthermore, hand contact with the stator leads increases the contamination of the crimped ends without allowing for cleaning, thus lowering the quality of the piercing and crimping. Additionally, it cannot guarantee the required length of the stator leads. Summary of the Invention

[0003] The purpose of this invention is to provide a stator piercing device for a series-wound motor to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A stator piercing device for a series-wound motor includes a support base and stator leads. A positioning cavity on one side of the top of the support base engages with a conveying outer casing. This serves two purposes: first, it provides some isolation to the outside of the stator leads, reducing the contact area between the stator leads and the outside environment at any given time, thus reducing the degree of contamination; second, it ensures the installation and fixation of the adjustment module and the length-fixing module. The outer wall of the conveying outer casing has multiple cutting openings to reduce material usage. These openings reduce the amount of raw materials used in the manufacturing of the conveying outer casing, saving materials and reducing its weight, thus improving its portability. Furthermore, the bottom of the conveying outer casing is fixedly connected to the support base via a plug-in mechanism, ensuring the quickness and stability of the connection between the conveying outer casing and the support base.

[0006] An adjustment module is connected to the upper end of the inner cavity of the external housing for conveying, and a length-fixing module is connected to the bottom end of the adjustment module. The length-fixing module and the adjustment module are used to fix the length of the stator lead wire and simultaneously complete the conveying of the stator lead wire.

[0007] The upper part of the support base is symmetrically connected with clamping parts to clamp and fix the stator lead wire ends and the piercing wire fittings. A terminal punch is provided above the clamping parts, so that the terminal punch is pressed down to complete the piercing wire connection of the stator lead wire.

[0008] The outer casing of the conveying device is symmetrically connected with limit modules on the side away from the clamping components. Through two sets of guide rollers in the limit mechanism, the part of the stator lead wire that is about to pass through the cleaning mechanism is stretched and limited to ensure the smooth cleaning effect of the cleaning mechanism on the stator lead wire. The limit module is connected to the cleaning mechanism, which cleans the contaminants on the upper and lower outer surfaces of the stator lead wire. The end of the stator lead wire passes through the middle of the limit module and the middle of the cleaning mechanism in sequence and enters the outer casing of the conveying device through the input port of the outer casing of the conveying device. The end of the stator lead wire passes through the fixed length modules again and is conveyed to the two clamping components through the output port of the outer casing of the conveying device.

[0009] Preferably, the insertion mechanism includes an insertion member and an insertion groove. The insertion member is fixedly bonded to the lower end of the outer housing of the conveying device. The insertion groove is formed in the support base, and the upper end of the insertion groove is connected to the positioning cavity. The insertion member is engaged in the insertion groove. When the lower end of the outer housing of the conveying device is engaged in the positioning cavity, the insertion member will also be engaged in the insertion groove, thereby strengthening the fixed connection between the outer housing of the conveying device and the support base.

[0010] The connector has a U-shaped structure, and the lower end of the connector has multiple reinforcing grooves to increase the contact area between the connector and the support base. The increase in contact area leads to an increase in the friction between the connector and the support base, thereby improving the stability of the connector in the connector grooves. This stability is then applied to the outer housing of the conveying equipment, thereby further improving the stability of the outer housing of the conveying equipment after installation.

[0011] Preferably, the adjustment module includes a driver and a positioning plate. The top of the driver is connected to the upper end face of the inner cavity of the conveying peripheral housing, and the positioning plate is connected to the lower end of the bottom output end of the driver. After the fixed length module is set, the driver is started, and the positioning plate is driven to rise and fall through the output end of the driver until the outer surface of the fixed length roller in the fixed length module contacts the upper surface of the stator lead wire, thereby ensuring the fixed length function of the fixed length module for the stator lead wire after the fixed length roller is replaced.

[0012] The actuator can be an electrically operated telescopic pole.

[0013] Preferably, the length-fixing module includes a length-fixing roller, a support roller, and a roller coiler. The roller coiler is connected to the lower end of the positioning plate via a mounting component, which can be a bolt. The length-fixing roller is detachably connected to the front end of the output end of the roller coiler. The support roller is located below the length-fixing roller, and the outer surfaces of the length-fixing roller and the support roller are in contact with the upper and lower surfaces of the stator lead wire, respectively. Depending on the required length of the stator lead wire, length-fixing rollers with different inner diameters are changed, and the replaced length-fixing rollers are connected to the roller coiler. After the length-fixing roller is replaced, the length-fixing roller is raised and lowered until the outer surface of the length-fixing roller contacts the stator lead wire through an adjustment module. The roller coiler is then activated, i.e., the number of rotations of the length-fixing roller is precisely controlled by a speed-regulating motor, and the length of the output stator lead wire is determined by taking the circumference of the outer surface of the length-fixing roller as a unit, thus completing the length-fixing operation of the stator lead wire.

[0014] The roller retainer can be a speed-regulating motor;

[0015] Both ends of the support roller are rotatably connected to the external housing of the conveyor via bearings, ensuring the support effect of the support roller on the stator lead wire while the rotatable support roller will not affect the conveying of the stator lead wire. Together with the fixed-length roller body, it realizes the restriction and conveying of the stator lead wire.

[0016] Both the outer surface of the fixed-length roller and the outer surface of the support roller are provided with circumferentially arranged slots, which play a certain role in anti-slip and improve the conveying effect and stability of the stator lead wire by the fixed-length roller and the support roller.

[0017] Preferably, the limiting module includes outward-inclined inclined members and guide rollers. The outward-inclined inclined members are symmetrically arranged above and below the stator lead-out line, and are fixedly bonded to the outer housing of the conveying device. The guide rollers are symmetrically arranged on the upper and lower sides of the stator lead-out line, and the two sets of guide rollers are respectively located between the two sets of outward-inclined inclined members located above and the two sets of outward-inclined inclined members located below. The guide rollers and the outward-inclined inclined members are rotatably connected by bearings. The outer surfaces of the two sets of guide rollers are in contact with the stator lead-out line. Through the two sets of guide rollers in the limiting mechanism, the part of the stator lead-out line that is about to pass through the cleaning mechanism is stretched and limited, ensuring the smooth cleaning effect of the cleaning mechanism on the stator lead-out line.

[0018] Preferably, the cleaning mechanism includes an assembly and an outer surface brushing component. The assembly is symmetrically arranged on the upper and lower sides of the stator lead wire. Both ends of the assembly are fixedly bonded to the outwardly inclined component. The outer surface brushing component is connected to the side of the assembly near the stator lead wire.

[0019] The outer surface brush is made of bristles, and the end of the bristles away from the assembly contacts the stator lead. When the stator lead passes through the upper and lower cleaning mechanisms, the outer surface brush will contact the upper and lower surfaces of the stator lead, brushing away the contaminants on the upper and lower surfaces of the stator lead.

[0020] Preferably, the assembly has a weight-reducing cavity inside, and the weight-reducing cavity extends through the assembly both front and back. The weight-reducing cavity reduces the material consumption of the assembly itself and reduces the weight of the assembly, so that the outward inclined member will not bear a large gravity, thereby enhancing the stability of the outward inclined member and the assembly.

[0021] The weight reduction cavity makes the assembly into an O-shaped structure, and the side of the assembly away from the stator lead wire is set as an inclined surface structure that is flush with the outward inclined component.

[0022] Preferably, an outer surface cleaning component is fixedly bonded to the side of the assembly near the outer housing of the conveying device. The side of the outer surface cleaning component near the stator lead is horizontal, and the horizontal surface of the outer surface cleaning component is in contact with the stator lead. When the stator lead passes through the outer surface cleaning component, the brushing of the outer surface brushing component causes the contaminants to loosen and a certain amount of contaminants to separate from the stator lead. The remaining contaminants are blocked by the outer surface cleaning component to prevent contaminants from entering the outer housing of the conveying device through the inlet of the outer housing of the conveying device, thereby reducing the interference of contaminants on the outer surface of the stator lead to the subsequent piercing and wiring operation.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: When using the present invention to pierce and crimp the stator leads, the end of the stator lead is conveyed between two sets of clamping members via a fixed-length roller, roller retainer, and support roller within the conveying outer housing. The stator lead is then pierced and crimped using a terminal punch. This eliminates the need for operators to hold the stator lead to fix its position, improving the automation level of the piercing and crimping device and reducing the contamination of the crimped end of the stator lead. The fixed-length roller and roller retainer solve the problem of not being able to guarantee the length of the stator lead. Before the stator lead is conveyed into the conveying outer housing, a cleaning mechanism cleans the upper and lower surfaces of the stator lead, reducing the interference of contaminants on the outer surface of the stator lead on the piercing and crimping operation.

[0035] Example 1

[0036] Please see Figures 1-4 As shown, a series-wound motor stator piercing device includes a support base 1 and stator leads 2. A positioning cavity 3 is opened on one side of the top of the support base 1 to engage a conveying outer housing 4. This serves two purposes: first, it provides a certain degree of isolation to the outside of the stator leads 2, reducing the contact area between the stator leads 2 and the outside environment at the same time, and reducing the degree of contamination of the stator leads 2; second, it ensures the installation and fixation of the adjustment module 6 and the length fixing module 7. The outer wall of the conveying outer housing 4 has a material reduction opening to reduce the amount of material used. The multiple material reduction openings can reduce the amount of raw materials used in the production of the conveying outer housing 4, saving materials and reducing the weight of the conveying outer housing 4, thus improving its portability. The bottom end of the conveying outer housing 4 is fixedly connected to the support base 1 through a plug-in mechanism 5, ensuring the quickness and stability of the fixed connection between the conveying outer housing 4 and the support base 1.

[0037] An adjustment module 6 is connected to the upper end of the inner cavity of the external housing 4 for conveying, and a length-fixing module 7 is connected to the bottom end of the adjustment module 6. The length-fixing module 7 and the adjustment module 6 are used to fix the length of the stator lead wire 2, and at the same time, the conveying of the stator lead wire 2 is completed.

[0038] The upper end of the support base 1 is symmetrically connected with clamping parts 8, which clamp and fix the end of the stator lead wire 2 and the piercing wire fitting. The clamping parts 8 are provided with terminal punches 9 above them, so that the terminal punches 9 are pressed down to complete the piercing wire connection of the stator lead wire 2.

[0039] The conveying peripheral housing 4 has symmetrically connected limit modules 10 on the side away from the clamping members 8. Two sets of guide rollers 102 in the limit mechanism stretch and limit the stator lead wire 2 before it passes the cleaning mechanism 11, ensuring the cleaning mechanism 11 effectively cleans the stator lead wire 2. The limit module 10 contains the cleaning mechanism 11, which cleans contaminants from the upper and lower outer surfaces of the stator lead wire 2. The end of the stator lead wire 2 passes sequentially between the limit module 10 and the cleaning mechanism 11, enters the conveying peripheral housing 4 through the input port, and then passes again between the length-fixing modules 7 before being conveyed from the output port of the conveying peripheral housing 4 to the space between the two clamping members 8.

[0040] refer to Figure 1 and Figure 2 As shown, the insertion mechanism 5 includes an insertion member 51 and an insertion groove. The insertion member 51 is fixedly bonded to the lower end of the conveying external housing 4. The insertion groove is opened in the bearing base 1, and the upper end of the insertion groove is connected to the positioning cavity 3. The insertion member 51 is engaged in the insertion groove. When the lower end of the conveying external housing 4 is engaged in the positioning cavity 3, the insertion member 51 will also be engaged in the insertion groove, thereby strengthening the fixed connection between the conveying external housing 4 and the bearing base 1.

[0041] The connector 51 has a U-shaped structure, and the lower end of the connector 51 has multiple reinforcing grooves to increase the contact area between the connector 51 and the support base 1. The increase in contact area leads to an increase in the friction between the connector 51 and the support base 1, thereby improving the stability of the connector 51 in the connector groove. This stability is then applied to the external housing 4 for conveying, thereby further improving the stability of the external housing 4 after installation.

[0042] refer to Figure 3 As shown, the adjustment module 6 includes a driver 61 and a positioning plate 62. The top of the driver 61 is connected to the upper end face of the inner cavity of the conveying peripheral housing 4. The positioning plate 62 is connected to the lower end of the bottom output end of the driver 61. After the length-fixing module 7 is set up, the driver 61 is started, and the positioning plate 62 is driven to rise and fall through the output end of the driver 61 until the outer surface of the length-fixing roller 71 in the length-fixing module 7 contacts the upper surface of the stator lead wire 2, thereby ensuring the length-fixing function of the length-fixing module 7 for the stator lead wire 2 after the length-fixing roller 71 is replaced.

[0043] The driver 61 can be an electrically operated telescopic pole.

[0044] refer to Figure 3As shown, the length-fixing module 7 includes a length-fixing roller 71, a support roller 72, and a roller coiler 73. The roller coiler 73 is connected to the lower end of the positioning plate 62 via a mounting component, which can be a bolt. The length-fixing roller 71 is detachably connected to the front end of the output end of the roller coiler 73. The support roller 72 is located below the length-fixing roller 71, and the outer surfaces of the length-fixing roller 71 and the support roller 72 respectively contact the upper and lower surfaces of the stator lead wire 2. Different inner lengths can be adjusted according to the required length of the stator lead wire 2. A fixed-length roller body 71 of the specified diameter is used, and the replaced fixed-length roller body 71 is connected to the roller body retainer 73. After the fixed-length roller body 71 is replaced, the fixed-length roller body 71 is raised and lowered through the adjustment module 6 until the outer surface of the fixed-length roller body 71 contacts the stator lead wire 2. The roller body retainer 73 is started, that is, the number of rotations of the fixed-length roller body 71 is precisely controlled by the speed regulating motor, and the length of the output of the stator lead wire 2 is determined by taking the circumference of the outer surface of the fixed-length roller body 71 as a unit, thus completing the fixed-length operation of the stator lead wire 2.

[0045] The roller body ring setter 73 can be a speed-regulating motor;

[0046] Both ends of the support roller 72 are rotatably connected to the external housing 4 for conveying via bearings. This ensures that the support roller 72 supports the stator lead wire 2 while the rotatable support roller 72 does not affect the conveying of the stator lead wire 2. Together with the fixed-length roller body 71, it achieves the restriction and conveying of the stator lead wire 2.

[0047] Both the outer surface of the fixed-length roller 71 and the outer surface of the support roller 72 are provided with circumferentially arranged slots, which play a certain anti-slip function and improve the conveying effect and stability of the fixed-length roller 71 and the support roller 72 on the stator lead wire 2.

[0048] refer to Figure 1 and Figure 2 As shown, the limiting module 10 includes an outward-inclined inclined member 101 and a guide roller 102. The outward-inclined inclined member 101 is symmetrically arranged above and below the stator lead wire 2, and is fixedly bonded to the conveying outer housing 4. The guide roller 102 is symmetrically arranged on the upper and lower sides of the stator lead wire 2, and the two sets of guide rollers 102 are respectively located between the two sets of outward-inclined inclined members 101 located above and the two sets of outward-inclined inclined members 101 located below. The guide roller 102 and the outward-inclined inclined member 101 are rotatably connected by bearings. The outer surfaces of the two sets of guide rollers 102 are in contact with the stator lead wire 2. Through the two sets of guide rollers 102 in the limiting mechanism, the part of the stator lead wire 2 that is about to pass through the cleaning mechanism 11 is stretched and limited, ensuring the smooth cleaning effect of the cleaning mechanism 11 on the stator lead wire 2.

[0049] refer to Figure 1 , Figure 2 and 4As shown, the cleaning mechanism 11 includes a component 111 and an outer surface brush 112. The component 111 is symmetrically arranged on the upper and lower sides of the stator lead 2. Both the front and rear ends of the component 111 are fixedly bonded to the outward inclined member 101. The outer surface brush 112 is connected to the side of the component 111 near the stator lead 2.

[0050] The outer surface brush 112 is a brush bristle, and the end of the brush bristle away from the assembly 111 is in contact with the stator lead 2. When the stator lead 2 passes through the upper and lower cleaning mechanisms 11, the outer surface brush 112 will contact the upper and lower surfaces of the stator lead 2 and brush away the contaminants on the upper and lower surfaces of the stator lead 2.

[0051] refer to Figure 1 , Figure 2 and 4 As shown, the assembly 111 has a weight-reducing cavity 113 inside, and the weight-reducing cavity 113 extends through the assembly 111 from both the front and back. The weight-reducing cavity 113 reduces the material consumption of the assembly 111 itself and reduces the weight of the assembly 111, so that the outward inclined member 101 will not bear a large gravity, thereby enhancing the stability of the outward inclined member 101 and the assembly 111.

[0052] The weight-reducing cavity 113 makes the assembly 111 have an O-shaped structure, and the side of the assembly 111 away from the stator lead wire 2 is set as an inclined surface structure that is flush with the outward inclined member 101.

[0053] refer to Figure 1 , Figure 2 and 4 As shown, an outer surface cleaning component 114 is fixedly bonded to the side of the assembly 111 near the external housing 4 for conveying. The side of the outer surface cleaning component 114 near the stator lead 2 is horizontal, and the horizontal surface of the outer surface cleaning component 114 is in contact with the stator lead 2. When the stator lead 2 passes through the outer surface cleaning component 114, the brushing of the outer surface brush 112 causes the contaminants to loosen and a certain amount of contaminants to separate from the stator lead 2. The remaining contaminants are blocked by the outer surface cleaning component 114 to prevent contaminants from entering the external housing 4 for conveying through the inlet of the external housing 4 for conveying, thereby reducing the interference of contaminants on the outer surface of the stator lead 2 on the subsequent piercing and wiring operation.

[0054] Working principle: The stator lead wire 2 ends pass sequentially through the middle of the limiting module 10 and the middle of the cleaning mechanism 11, and enter the conveying external housing 4 through the input port. The stator lead wire 2 ends then pass between the fixed-length roller 71 and the support roller 72, and are conveyed to the two clamping members 8 through the output port of the conveying external housing 4. The stator lead wire 2 ends are pierced and connected by the terminal punch 9. The fixed-length roller 71 with different inner diameter specifications is changed according to the required length of the stator lead wire 2. After the change, the fixed-length roller 71 is raised and lowered by the adjustment module 6 until the outer surface of the fixed-length roller 71 contacts the stator lead wire 2. The roller retainer 73 is activated, that is, the number of rotations of the fixed-length roller 71 is precisely controlled by the speed regulating motor. The outer circumference is defined as a unit, thus determining the output length of the stator lead 2 and completing the length-fixing operation of the stator lead 2. When the stator lead 2 passes through the cleaning mechanism 11, the upper and lower sets of outer surface brushing members 112 brush away the contaminants on the upper and lower surfaces of the stator lead 2. When it passes through the upper and lower sets of outer surface cleaning members 114, it is pushed by the outer surface cleaning members 114, thereby preventing contaminants from entering the conveying peripheral housing 4 through the input port of the conveying peripheral housing 4, reducing the interference of contaminants on the outer surface of the stator lead 2 on the subsequent piercing and wiring operation. The two sets of guide rollers 102 in the limiting mechanism stretch and limit the part of the stator lead 2 that is about to pass through the cleaning mechanism 11, ensuring the smooth cleaning effect of the cleaning mechanism 11 on the stator lead 2.
