Description

Technical Field

[0001] This invention relates to the field of flat wire motor processing equipment, and more particularly to a stator wire end clamping device for flat wire motors. Background Technology

[0002] In the field of flat wire motor processing, increasingly stringent requirements have been placed on shortening the length of the bare copper wire segment before welding the stator end windings in order to achieve a compact motor structure. This trend poses a greater challenge to the design of welding fixtures, requiring them to possess high precision, high reliability, and excellent process accessibility within a very small operating space.

[0003] Currently, the common method for clamping and positioning copper wires involves manually setting up upper and lower clamping discs and rotating the entire assembly in a circular motion. However, this clamping method has significant drawbacks. Because it uses a uniform circular rotation, it's difficult to perform independent and precise fine-tuning of individual or localized copper wires, resulting in uneven and tight contact between the clamped parallel copper wires. This makes it impossible to stably control the radial clearance between the copper wires within the ideal range. Excessive clearance can cause serious laser leakage problems during subsequent laser welding, failing to meet the quality requirements of laser welding. Summary of the Invention

[0004] The purpose of this invention is to provide a stator wire end clamping device for flat wire motors to solve the aforementioned problems of clamping discs in related technologies.

[0005] To address the aforementioned problems in the existing technology, the present invention adopts the following technical solution:

[0006] The stator wire end clamping device for a flat wire motor includes:

[0007] frame;

The clamping disc is disposed on the frame, and the drive assembly is movably disposed on the clamping disc and is drivenly connected to a first motor. The clamping disc has a sliding groove. Along the radial direction of the clamping disc, the clamping jaw, the floating outer jaw, and the floating inner jaw are sequentially slidably disposed in the sliding groove. The clamping block is fixedly disposed in the sliding groove and located in the fixing hole of the floating inner jaw. The clamping jaw is connected to the drive assembly. Under the action of the first motor, along the radial direction of the clamping disc, the clamping jaw clamps the stator wire ends sequentially between the floating outer jaw and the floating outer jaw, between the floating outer jaw and the floating inner jaw, and between the floating inner jaw and the clamping block.

[0010] As an optional technical solution, the drive assembly includes a spiral gear, a first cam roller, a push rod, and a first elastic element. The spiral gear is rotatably mounted on the clamping plate and is connected to the output end of the first motor. One end of the first cam roller is connected to the cam surface of the spiral gear, and the other end of the first cam roller is connected to the push rod. The push rod is slidably mounted on the clamping plate, and both ends of the push rod are connected to the first elastic element and the clamping claw, respectively. The first elastic element is elastically mounted on the clamping plate. The spiral gear can drive the push rod to move linearly, so that the push rod can push the clamping claw to move linearly synchronously under the action of the first elastic element.

[0011] As an optional technical solution, the end of the clamping claw is provided with a movable part, and the end of the push rod is provided with a groove. The movable part is movably disposed in the groove, so that the clamping claw and the push rod can move relative to each other in the radial direction of the clamping plate.

[0012] As an optional technical solution, the clamping mechanism further includes a reset component, which includes a second elastic element and a reset element. The reset element is slidably disposed on the clamping disc and abuts against the floating inner jaw. One end of the second elastic element is connected to the reset element, and the other end of the second elastic element is connected to the clamping disc. The second elastic element is always in a compressed state.

[0013] As an optional technical solution, the clamping mechanism further includes a third elastic element. The clamping disc is provided with a fixing groove, and the third elastic element is located in the fixing groove. One end of the third elastic element is connected to the inner sidewall of the fixing groove, and the other end of the third elastic element is connected to the floating external claw. The third elastic element is always in a compressed state.

[0014] As an optional technical solution, a quick-release mechanism is also included. The quick-release mechanism includes a mounting base, a handle, and a locking element. The mounting base and the handle are fixedly connected to the clamping plate. The locking element is rotatably disposed on the mounting base and can be inserted into the frame, so that the clamping plate can be locked or unlocked relative to the frame.

[0015] As an optional technical solution, a tooth protection mechanism is also included. The tooth protection mechanism includes a second motor, a tooth protection disc, a drive disc, a second cam roller, and tooth protection. The second motor and the tooth protection disc are both mounted on the frame. The second motor is connected to the drive disc for transmission. The drive disc is rotatably mounted on the tooth protection disc. The second cam roller is slidably mounted on the tooth protection disc and passes through the drive disc. The tooth protection is connected to the second cam roller and can extend and retract relative to the tooth protection disc. The tooth protection can be inserted into the gap between adjacent copper wires of the stator along the circumferential direction of the tooth protection disc.

[0016] As an optional technical solution, the tooth protection disc is provided with a first sliding groove, which extends radially along the tooth protection disc, and the drive disc is provided with a second sliding groove, the length direction of the second sliding groove being at an angle to the length direction of the first sliding groove.

[0017] As an optional technical solution, a dust collection chamber is also included. The dust collection chamber is disposed on the frame and has a through hole. The dust collection chamber is arranged around the wire ends of the stator through the through hole.

[0018] As an optional technical solution, a lifting mechanism is also included. The lifting mechanism includes a telescopic drive source and a support base. The fixed end of the telescopic drive source is disposed on the frame, and the telescopic end of the telescopic drive source is connected to the support base. The support base is disposed at the bottom of the stator and is used to support the tail of the stator.

[0019] The flat wire motor stator wire end clamping device provided by the present invention has at least the following beneficial effects:

[0020] The stator wire end clamping device for a flat wire motor includes a frame, a first motor, and a clamping mechanism. The first motor is mounted on the frame. The clamping mechanism includes a clamping disc, a drive assembly, a clamping claw, a floating outer claw, a floating inner claw, and a clamping block. The clamping disc is mounted on the frame, and the drive assembly is movably mounted on the clamping disc and is connected to the first motor. The clamping disc has a groove. Along the radial direction of the clamping disc, the clamping claw, the floating outer claw, and the floating inner claw are slidably disposed in the groove. The clamping block is fixedly disposed in the groove and located in the fixing hole of the floating inner claw. The clamping claw is connected to the drive assembly. When each wire end of the stator is placed in the corresponding clamping hole, under the action of the first motor, along the radial direction of the clamping disc, the wire ends of the stator are clamped sequentially between the clamping claw and the floating outer claw, between the floating outer claw and the floating inner claw, and between the floating inner claw and the clamping block. This flat wire motor stator wire head clamping device can automatically clamp the stator wire head as a whole. It adopts a radial clamping method, which effectively ensures that the adjacent wire heads are tightly fitted after clamping. Laser welding will not leak light, and the welding area and pull-out force meet the requirements. Attached Figure Description

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] like Figures 1 to 14 As shown, this embodiment provides a stator wire end clamping device for a flat wire motor. The flat wire motor stator wire end clamping device includes a frame 1, a first motor 2, and a clamping mechanism 3. The first motor 2 is mounted on the frame 1. The clamping mechanism 3 includes a clamping disc 31, a drive assembly, a clamping claw 33, a floating outer claw 34, a floating inner claw 35, and a clamping block 36. The clamping disc 31 is mounted on the frame 1, and the drive assembly is movably mounted on the clamping disc 31 and is connected to the first motor 2 via a transmission connection. The clamping disc 31 has a sliding groove. Along the radial direction of the clamping disc 31, the top clamping claw 33, the floating outer claw 34, and the floating inner claw 35 are sequentially slidably disposed in the sliding groove. The top clamping block 36 is fixedly disposed in the sliding groove and located in the fixing hole of the floating inner claw 35. The top clamping claw 33 is connected to the drive assembly. Under the action of the first motor 2, along the radial direction of the clamping disc 31, the top clamping claw 33 and the floating outer claw 34, the floating outer claw 34 and the floating inner claw 35, and the floating inner claw 35 and the top clamping block 36 sequentially clamp the various wire ends 101 of the stator 100.

[0050] The first motor 2 is a servo motor. Both the first motor 2 and the clamping plate 31 are mounted on the frame 1. The output end of the first motor 2 is connected to the drive assembly via gears. The clamping plate 31 is provided with a fixing groove. The drive assembly is a slide rod and is elastically connected by a spring to ensure that the drive assembly can return to its original position. Under the driving action of the first motor 2, the drive assembly can slide radially within the fixing groove of the clamping plate 31.

[0051] The clamping disc 31 has multiple radiating grooves along its circumference. Along the extension direction of the grooves, a top clamping claw 33 is slidably disposed at one end of the groove, a floating inner claw 35 is slidably disposed at the other end of the groove, and a floating outer claw 34 is located between the top clamping claw 33 and the floating inner claw 35 and slidably disposed within the groove. The floating inner claw 35 has a fixing hole, and a top clamping block 36 is located within the fixing hole and connected to the clamping disc 31, with the top clamping block 36 fixed relative to the groove and the floating inner claw 35. A first clamping hole is located between the top clamping claw 33 and the floating outer claw 34, a second clamping hole is located between the floating outer claw 34 and the floating inner claw 35, and a third clamping hole is located between the floating inner claw 35 and the top clamping block 36. These three clamping holes are used to clamp and fix the corresponding wire ends 101 of the stator 100.

[0052] In this embodiment, there are three wire ends 101 of the stator 100 along the radial direction of the stator 100. Each wire end 101 of the stator 100 is placed in a corresponding clamping hole. The driving assembly can drive the clamping claw 33 to slide in the slide groove. The diameter of the first clamping hole first decreases and then remains constant. The clamping claw 33 abuts against one side of the first wire end 101, and the other side of the first wire end 101 abuts against and pushes the floating outer claw 34 to slide in the slide groove. At this time, the clamping claw 33 and the floating outer claw 34 always clamp the first wire end 101. Then, the floating outer claw 34 slides in the slide groove, the diameter of the second clamping hole first decreases and then remains constant, the floating outer claw 34 abuts against one side of the second wire end 101, and the other side of the second wire end 101 abuts against and pushes the floating inner claw 35 to slide in the slide groove. At this time, the floating outer claw 34 and the floating inner claw 35 clamp the second wire end 101. Finally, the floating inner jaw 35 slides within the groove, the diameter of the third clamping hole first decreases and then remains constant, the wall of the fixed hole of the floating inner jaw 35 abuts against one side of the third wire end 101, and the other side of the third wire end 101 abuts against the clamping block 36. At this point, the floating inner jaw 35 and the clamping block 36 clamp the third wire end 101. This flat wire motor stator wire end clamping device can achieve overall automatic clamping of the stator 100 wire end 101, solving the problem that the traditional clamping disc 31 is too close to the enamel of the wire end 101 and is prone to burning the enamel. The actual contact between the jaws of the clamping mechanism 3 and the bare copper section of the wire end 101 is only 1.5mm, and the distance from the enamel is 1.5mm, ensuring that the weld joint of the stator 100 wire end 101 will not stick to the jaws of the clamping mechanism 3 after laser welding. Furthermore, the radial clamping method effectively ensures that the adjacent wire ends 101 are tightly fitted after clamping, preventing light leakage during laser welding, and meeting the requirements for welding area and pull-out force.

[0053] Furthermore, referring to Figure 4 , Figure 7 , Figure 9 as well as Figure 11 The drive assembly includes a spiral gear 321, a first cam roller 322, a push rod 323, and a first elastic element 324. The spiral gear 321 is rotatably mounted on the clamping plate 31 and is connected to the output end of the first motor 2. One end of the first cam roller 322 is connected to the cam surface of the spiral gear 321, and the other end of the first cam roller 322 is connected to the push rod 323. The push rod 323 is slidably mounted on the clamping plate 31, and both ends of the push rod 323 are connected to the first elastic element 324 and the clamping claw 33, respectively. The first elastic element 324 is elastically mounted on the clamping plate 31. The spiral gear 321 can drive the push rod 323 to move linearly, so that the push rod 323 can push the clamping claw 33 to move linearly synchronously under the action of the first elastic element 324.

[0054] The spiral gear 321 is driven by the first motor 2. The first elastic element 324 is a rectangular spring. The clamping plate 31 has a through groove, in which the first elastic element 324 and the push rod 323 are disposed. The first cam roller 322 is mounted on the push rod 323 and closely adheres to the cam surface of the spiral gear 321. The push rod 323 pushes the clamping pawl 33 through the first elastic element 324. Under the driving action of the first motor 2, the spiral gear 321 is driven to rotate. The cam surface of the spiral gear 321 pushes the first cam roller 322, which is released from it. Since the cam surface is an Archimedean spiral, the first cam roller 322 is pushed towards the center, thereby driving the push rod 323 to move rapidly in the clamping direction. At this time, the clamping pawl 33 does not contact the wire end 101, and the first elastic element 324 maintains its original length. When the clamping claw 33 contacts the wire end 101 of the stator 100, the push rod 323 continues to advance under the continuous push of the cam surface. The first elastic element 324 gradually lengthens. Under the elastic action of the first elastic element 324, the clamping force is large and easy to control. Finally, after the laser welding of the wire end 101 of the stator 100 is completed, the first motor 2 stops. Under the action of the first elastic element 324, the clamping claw 33 disengages from the wire end 101 of the stator 100, and the push rod 323 retracts.

[0055] Furthermore, referring to Figure 9 The clamping claw 33 has a movable part 331 at its end, and the push rod 323 has a groove at its end. The movable part 331 is movably disposed within the groove, allowing the clamping claw 33 and the push rod 323 to move relative to each other radially along the clamping plate 31. The movable part 331 is configured as a hook. The width of the groove on the push rod 323 is greater than the thickness of the movable part 331, allowing the movable part 331 to move within the groove. The clamping claw 33 and the push rod 323 can move relative to each other radially along the clamping plate 31. When clamping the wire end 101 of the stator 100, the clamping claw 33 can move freely to adaptively adjust the gap between itself and the floating inner claw 35, ensuring better adaptation to the size of the wire end 101 of the stator 100.

[0056] Furthermore, referring to Figure 11 and Figure 13 The clamping mechanism 3 also includes a reset assembly 4, which includes a second elastic member 41 and a reset member 42. The reset member 42 is slidably disposed on the clamping plate 31 and abuts against the floating inner jaw 35. One end of the second elastic member 41 is connected to the reset member 42, and the other end of the second elastic member 41 is connected to the clamping plate 31. The second elastic member 41 is always in a compressed state.

[0057] The second elastic element 41 is configured as a return spring. Under the action of the first motor 2, along the radial direction of the clamping plate 31, the top jaw 33 and the floating outer jaw 34, the floating outer jaw 34 and the floating inner jaw 35, and the floating inner jaw 35 and the top jaw block 36 sequentially clamp the various wire ends 101 of the stator 100. The floating inner jaw 35 can press against and push the return element 42, and the second elastic element 41 is compressed. After the laser welding of the stator 100 wire ends 101 is completed, the first motor 2 stops and there is no driving force acting on the clamping mechanism 3. Under the elastic action of the second elastic element 41, the return element 42 returns to the initial position. The return element 42 pushes the floating inner jaw 35 to slide in the opposite direction and return to the initial position, which facilitates the subsequent clamping process of the stator 100 wire ends 101.

[0058] Furthermore, referring to Figure 9 and Figure 11 The clamping mechanism 3 also includes a third elastic element 37. The clamping plate 31 is provided with a fixing groove. The third elastic element 37 is located in the fixing groove. One end of the third elastic element 37 is connected to the inner side wall of the fixing groove, and the other end of the third elastic element 37 is connected to the floating outer claw 34. The third elastic element 37 is always in a compressed state.

[0059] The third elastic element 37 is configured as a return spring. The drive assembly can drive the clamping claw 33 to slide within the groove. The clamping claw 33 abuts against one side of the first wire end 101, and the other side of the first wire end 101 abuts against and pushes the floating outer claw 34 to slide within the groove. At this time, the clamping claw 33 and the floating outer claw 34 always clamp the first wire end 101. After the laser welding of the stator 100 wire end 101 is completed, under the elastic action of the third elastic element 37, the floating outer claw 34 slides in the opposite direction and returns to its initial position, facilitating the subsequent clamping process of the stator 100 wire end 101.

[0060] Furthermore, referring to Figure 12 The flat wire motor stator wire end clamping device also includes a quick release mechanism 5. The quick release mechanism 5 includes a mounting base 51, a handle 52, and a locking element 53. The mounting base 51 and the handle 52 are fixedly connected to the clamping plate 31. The locking element 53 is rotatably set on the mounting base 51 and can be inserted into the frame 1, so that the clamping plate 31 can be locked or unlocked relative to the frame 1.

[0061] Both the mounting base 51 and the handle 52 are fixedly mounted on the clamping plate 31, forming a relatively stable connection. The locking element 53 is rotatably mounted on the mounting base 51, and can selectively insert into or disengage from the corresponding structure on the frame 1, thereby switching the connection state between the clamping plate 31 and the frame 1. When locking is required, after placing the clamping plate 31 in the corresponding position on the frame 1, the locking element 53 is inserted into the connection hole of the frame 1. The operator can rotate the locking element 53 to lock it in the connection hole. At this time, the position of the clamping plate 31 is fixed relative to the frame 1, realizing the locking function.

[0062] When unlocking is required, the locking element 53 is reversed to disengage it from the frame 1, thus releasing the fixed connection between the clamping disc 31 and the frame 1, allowing the clamping disc 31 to move or be removed relative to the frame 1. This quick-release mechanism 5 allows users to quickly and easily lock and unlock the clamping disc 31 without additional tools, effectively improving the ease of use and maintenance efficiency of the device. The handle 52 facilitates the removal of the clamping disc 31 from the frame 1 for cleaning, and allows for the replacement of the cleaned clamping disc 31, ensuring minimal downtime and low maintenance costs.

[0063] Furthermore, referring to Figure 5 , Figure 6 and Figure 8 The stator wire clamping device for the flat wire motor also includes a tooth protection mechanism 6. The tooth protection mechanism 6 includes a second motor, a tooth protection disc 61, a drive disc 62, a second cam roller 63, and a tooth protection 64. The second motor and the tooth protection disc 61 are both mounted on the frame 1. The second motor is connected to the drive disc 62. The drive disc 62 is rotatably mounted on the tooth protection disc 61. The second cam roller 63 is slidably mounted on the tooth protection disc 61 and passes through the drive disc 62. The tooth protection 64 is connected to the second cam roller 63 and can extend and retract relative to the tooth protection disc 61. The tooth protection 64 can be inserted into the gap between adjacent copper wires of the stator 100 along the circumferential direction of the tooth protection disc 61.

[0064] The toothed disc 61 has a first groove 611 extending radially along the toothed disc 61. The drive disc 62 has a second groove 621, the length direction of which is at an angle to the length direction of the first groove 611. The second motor is a servo motor, and its output end is connected to the drive disc 62 via gears. Under the action of the second motor, the second motor drives the drive disc 62 to rotate, allowing the second cam roller 63 to slide along the extension directions of the first groove 611 and the second groove 621. The toothed disc 64 can extend and retract relative to the toothed disc 61, allowing it to be inserted into the gap between adjacent copper wires of the stator 100 along the circumference of the toothed disc 61. The toothed disc 64 supports the wire tail 102 of the stator 100, ensuring that it does not sink or loosen during the clamping of the wire head 101 of the stator 100, preventing the copper wire from shifting, and also preventing the insulation paper from shifting or even breaking.

[0065] Furthermore, referring to Figure 1 and Figure 3 The flat wire motor stator wire end clamping device also includes a dust collection chamber 7, which is set on the frame 1. The dust collection chamber 7 has a through hole 71 and is arranged around the wire end 101 of the stator 100 through the through hole 71.

[0066] The dust collection chamber 7 has multiple suction holes on its inner circumferential wall of the through hole 71, spaced apart along the circumference of the through hole 71. A dust discharge hole is located on the outer circumference of the dust collection chamber 7. When the dust collection chamber 7 is activated, impurities generated from the laser welding of the stator 100 wire ends 101 are drawn in through the suction holes and discharged through the dust discharge holes, effectively cleaning the device.

[0067] Furthermore, referring to Figures 1-2 The flat wire motor stator wire end clamping device also includes a lifting mechanism 8. The lifting mechanism 8 includes a telescopic drive source 81 and a support base 82. The fixed end of the telescopic drive source 81 is set on the frame 1, and the telescopic end of the telescopic drive source 81 is connected to the support base 82. The support base 82 is set at the bottom of the stator 100 and is used to support the wire end 102 of the stator 100.

[0068] The telescopic drive source 81 is configured as a lifting cylinder, and the stator 100 is fixed on the support base 82. Driven by the lifting cylinder, the support base 82 rises vertically relative to the frame 1, allowing the wire end 101 of the stator 100 to be inserted into the corresponding clamping hole of the clamping mechanism 3. The clamping mechanism 3 clamps and fixes the wire end 101 of the stator 100, facilitating laser welding. After welding is completed, driven by the lifting cylinder, the support base 82 descends vertically relative to the frame 1, allowing the operator to easily remove the stator 100. The support base 82 is configured as a crown support to support and fix the wire end 102 of the stator 100, preventing the copper wire from shifting vertically.
