Description

Technical Field

[0001] This invention relates to the field of stator processing technology, and more specifically, to a device for grouping and rolling welding of segmented stators. Background Technology

[0002] Segmented stators, due to their advantages such as high material utilization and ease of automated winding, have been widely used in new energy vehicles, industrial servo systems, and other fields. A typical manufacturing process includes: assembling multiple wound segmented stators into a circle, welding the seams between adjacent segments, and inspecting the inner and outer diameters after welding. The efficiency of each process directly affects the output capacity of the entire production line.

[0003] Currently, the processing of segmented stators generally adopts a decentralized operation mode. In cases such as... Figure 16 When processing the segmented stator 11, the encircling and rolling, welding, and dimensional inspection are all completed by independent equipment, and the workpieces are transferred between equipment by manual or semi-automatic handling tools. Taking the encircling and rolling as an example, the annular stator assembly, which has been initially formed into a circle by the rolling device, is still in a loose state that is not completely fixed. The operator must carefully remove it and transfer it to the welding station. After clamping, positioning, and pressing, welding can be carried out. After welding, the stator assembly needs to be transported to the inspection station for inner and outer diameter measurement. In this process, each process requires independent loading, positioning, clamping, and unloading operations. The auxiliary time is much longer than the actual processing time, and the cycle time of each process is mismatched, resulting in low production efficiency of the entire line.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0021] like Figure 1 As shown, a segmented stator group rolling and welding device includes a worktable 1, on which a preliminary rolling mechanism 2, a positioning welding mechanism 3, and an outer diameter detection mechanism 4 are sequentially arranged; the worktable 1 is also provided with a primary transport mechanism 5 for transferring segmented stators 11, the primary transport mechanism 5 includes a conveying bracket 501, an outer clamping assembly and an inner clamping assembly, and also includes a drive device for driving the outer clamping assembly and the inner clamping assembly to move along the length direction of the conveying bracket 501 (which is an existing linear reciprocating drive mechanism, which will not be described in detail in this embodiment). The outer clamping assembly includes an outer clamping jaw 502, the inner clamping assembly includes an inner clamping jaw 503, and also includes two first driving components (specifically cylinders, the installation and driving methods of which are existing technologies, which will not be described in detail in this embodiment) for controlling the lifting and lowering of the outer clamping jaw 502 and the inner clamping jaw 503 respectively.

[0022] like Figure 15As shown, the outer clamping jaw 502 includes a first pneumatic jaw 504. The jaw portion of the first pneumatic jaw 504 is provided with an L-shaped connecting rod 505. The bottom end of the L-shaped connecting rod 505 is provided with an arc-shaped positioning rod 506. The arc-shaped positioning rod 506 is used to fit against the outer side wall of the segmented stator 11 so as to achieve stable gripping of the segmented stator 11 during clamping. The outer clamping jaw 502 is used to transfer the segmented stator 11 on the preliminary rolling mechanism 2 to the positioning welding mechanism 3.

[0023] The inner clamping jaw 503 includes a second pneumatic jaw 507; each jaw portion is provided with a vertical support rod 508, and limiting grooves 509 are respectively formed on the outer side walls of the two support rods 508 facing away from each other; the second pneumatic jaw 507 drives the support rods 508 to open outward, thereby achieving internal clamping of the segmented stator 11. This facilitates the transfer of the welded segmented stator 11 to the outer diameter detection mechanism 4. Two sets of inner clamping assemblies are provided, one for transferring the welded segmented stator 11 to the outer diameter detection mechanism 4, and the other simultaneously transferring the segmented stator 11 that has completed outer diameter detection to the next process, thereby improving transfer efficiency and realizing parallel operation of two workstations.

[0024] like Figure 2-8 As shown, the preliminary rolling mechanism 2 includes a sliding table 201 disposed on the workbench 1 at the starting end of the conveying bracket 501. The sliding table 201 slides on the surface of the workbench 1 along a direction perpendicular to the conveying direction of the conveying bracket 501. It also includes a second driving member (which is an existing linear reciprocating driving mechanism, which will not be described in detail in this embodiment) for driving the sliding table 201 to move closer to or away from the conveying bracket 501. The surface of the sliding table 201 is provided with a plurality of vertically extending and sequentially arranged enclosing auxiliary strips 202 in the horizontal direction. The plurality of enclosing auxiliary strips 202 are sequentially hinged end to end to form a flexible chain structure. The number of enclosing auxiliary strips 202 is equal to the number of segmented stators 11 to be rolled. Each enclosing auxiliary strip 202 has a detachable connecting structure on the side surface for mounting the segmented stators 11. It also includes a driving component, which is connected to the chain structure and is used to drive the chain structure to bend and enclose into a ring.

[0025] By setting multiple enclosing auxiliary strips 202 that are hinged end to end on the workbench 1 to form a flexible chain structure, each enclosing auxiliary strip 202 is provided with a detachable connection structure for connecting the segmented stator 11. The chain structure is driven by the drive component to gradually bend and enclose into a ring, realizing the overall one-time rolling of the segmented stator 11 without the need for manual placement and assembly, greatly reducing manual intervention.

[0026] An arc-shaped positioning block 203 is provided on the inner surface of the enclosing auxiliary strip 202. Two arc-shaped positioning blocks 203 are provided, located at the middle and bottom of the enclosing auxiliary strip 202 respectively. When the chain-like structure is enclosed into a circle, the arc-shaped positioning blocks 203 together form a complete ring. During the rolling process, the segmented stator 11 is radially assisted in positioning to prevent misalignment of the inner ring of the segmented stator 11 due to hinge gaps or bending deformation. After the rolling is completed, the complete circular arc-shaped positioning block 203 can be used as an inner diameter reference to ensure the roundness of the inner circle of the stator.

[0027] The drive assembly includes a drive block 204 slidably connected to the worktable 1, and a third drive component for moving the drive block 204 closer to or further away from the chain structure (the third drive component is an existing linear reciprocating drive mechanism such as a cylinder, electric cylinder, linear module, etc., which will not be described in detail in this embodiment); each end of the drive block 204 is provided with a horizontal connecting rod 205, and the end of each connecting rod 205 is hinged to a drive claw 206. The free ends of the two drive claws 206 are respectively hinged to the two outermost enclosing auxiliary strips 202. The drive block 204 drives the connecting rods 205 and drive claws 206 on both sides to move synchronously, and applies bending force from both ends of the chain structure at the same time, so that the enclosing process is smooth and symmetrical, avoiding the deflection caused by unilateral drive.

[0028] The driving claw 206 includes a base 207 hinged to the connecting rod 205. The base 207 bends in the direction of the other driving claw 206 to form a bent portion 208, and the bent portion 208 continues to bend in the same direction to form an extension 209. The inward bending of the bent portion 208 and the extension 209 allows the driving claw 206 to naturally pull the outermost enclosing auxiliary strip 202 along the circumferential tangential direction when it follows the driving block 204, thereby guiding the entire chain-like structure to bend into a circle and avoiding interference between the straight driving claw 206 and the enclosing auxiliary strip 202 during the bending process.

[0029] The connecting rod 205 includes a main rod 210 fixed to the drive block 204. A sliding groove is formed at one end of the main rod 210 facing the chain structure. A secondary rod 211 is slidably disposed within the sliding groove. A first spring 212 is provided between the bottom wall of the sliding groove and the end of the secondary rod 211. A limiting groove 213 communicating with the sliding groove is formed along the length of the side wall of the main rod 210. A limiting block 214 slidably engages with the limiting groove 213 on the secondary rod 211. At the start of the rolling process, the first spring 212 is in its natural state. As the chain structure gradually bends, the secondary rod 211 slides into the main rod 210, compressing the first spring 212. When the circle is just formed, the first spring 212 still retains a margin for further compression, allowing the drive assembly to continue moving a small overtravel, avoiding rigid collisions that could damage components. Simultaneously, the elastic force generated by compressing the first spring 212 continuously acts on the enclosing auxiliary strip 202, ensuring a smooth and reliable rolling process.

[0030] The connecting structure includes a T-shaped strip 215 vertically arranged on the inner surface of the top of the enclosing auxiliary strip 202. The outer surface of the segmented stator 11 has a T-shaped groove 1101 extending through its upper and lower ends. The T-shaped groove 1101 slides into the T-shaped strip 215. The T-shaped fit enables quick assembly and disassembly. The operator or the automatic feeding mechanism 6 can slide the segmented stator 11 from top to bottom into the T-shaped strip 215. The enclosing auxiliary strip 202 has an abutment part at the bottom of the T-shaped strip 215 to position the segmented stator 11 vertically, thereby facilitating the placement of the segmented stator 11 without the need for screws or clamps, and significantly shortening the material change time.

[0031] A vertical abutment plate 216 is provided on the surface of the workbench 1 on the side of the chain structure facing the drive assembly. Before the enclosing operation, each enclosing auxiliary strip 202 abuts against the side wall of the abutment plate 216 facing the chain structure. The two ends of the abutment plate 216 are provided with grooves 217 for the drive claw 206 to pass through, which prevents the abutment plate 216 from interfering with the movement of the drive claw 206. The abutment plate 216 provides a precise straight line reference for the initial state of the chain structure, ensuring that all enclosing auxiliary strips 202 are neatly arranged and uniformly spaced before rolling, thereby improving the consistency of the starting position of rolling.

[0032] Several sets of compaction components are provided on the surface of the workbench 1 on the side of the chain structure facing away from the drive assembly. The compaction components include compaction cylinders 218. Several fixing plates 219 are provided on the workbench 1 for installing the compaction cylinders 218. The compaction cylinders 218 are distributed circumferentially along the chain structure after it is enclosed into a circle. A guide plate 220 is slidably connected to the fixing plate 219. A vertical abutment roller 221 is rotatably connected to the end of the guide plate facing the chain structure. The number of abutment rollers is half the number of enclosing auxiliary strips 202. After the rolling is completed, the compaction cylinders 218 drive the guide plate to move toward the corresponding enclosing auxiliary strip 202, thereby controlling the abutment roller to press against the outer side of the corresponding enclosing auxiliary strip 202, applying radial pressure to one side of the enclosing auxiliary strip 202, further compacting the splicing surface of each segment of the stator 11, eliminating hinge gaps or elastic deformation, and improving the roundness of the stator.

[0033] A lifting plate 222 is vertically connected to the center of the chain-like structure after it is enclosed into a circle on the surface of the worktable 1. The lifting plate is located above the arc-shaped positioning block 203. A fifth driving component (such as a cylinder or electric cylinder, not shown in the figure) is provided at the bottom of the worktable 1 to drive the lifting plate to rise and fall. After the rolling is completed, the lifting plate rises and pushes the entire enclosed segmented stator 11 upward, making it easy for manual or material handling devices to unload the material.

[0034] An automatic feeding mechanism 6 is installed on one side of the chain structure on the surface of the workbench 1. The automatic feeding mechanism 6 includes a feeding bracket 601, on which a feeding assembly is mounted. The feeding assembly includes a feeding gripper group 602 and a fourth driving component (the fourth driving component is an existing linear reciprocating drive mechanism, such as a cylinder, electric cylinder, linear module, etc., which will not be described in detail in this embodiment) for driving the feeding gripper group 602 to achieve horizontal and vertical movement. The feeding gripper group 602 includes a mounting frame 603 and multiple horizontally arranged pneumatic grippers 604 disposed at the bottom of the mounting frame 603. The segmented stators 11 are pre-clamped in the feeding gripper group 602 by manual operation or a feeding device, realizing the automatic feeding of the segmented stators 11 without the need for manual placement of each one onto the enclosing auxiliary strip 202, thus improving the production cycle.

[0035] like Figure 9 and Figure 10 The positioning and welding mechanism 3 includes a positioning component and a welding component. The positioning component includes a rotary spindle 301 that is vertically and rotatably connected to the worktable 1, and a sixth driving component (such as a motor and sprocket chain, which will not be described in detail in this embodiment) for driving the rotary spindle 301 to rotate. The top of the rotary spindle 301 is provided with a positioning fixture 302 for positioning the segmented stators 11. The rotary spindle 301 is provided with a plurality of clamping components corresponding to each segmented stator 11. The number of clamping components is equal to the number of segmented stators 11, and they are used to clamp the outer side wall of the corresponding segmented stator 11. The worktable 1 is also provided with a welding component on one side of the positioning component.

[0036] The segmented stator 11 is initially positioned by the positioning fixture 302 and the clamping assembly, which realizes the all-round stable constraint of the loose ring stator assembly. At the same time, the rotary spindle 301 can be precisely indexed and rotated under the drive assembly. With the welding assembly fixed on one side, each splice seam can be automatically welded in sequence without the need for manual handling of workpieces or movement of welding gun, which greatly improves welding efficiency.

[0037] The positioning fixture 302 is annular, and its top is evenly provided with a number of arc-shaped positioning plates 303 corresponding to the number of segmented stators 11 along its circumference. The inner wall of the arc-shaped positioning plate 303 is provided with positioning strips 304 that cooperate with the T-slots 1101 of the segmented stators 11. By placing the initially enclosed segmented stators 11 on the top of the positioning fixture 302, the circumferential and radial degrees of freedom of the segmented stators 11 are restricted by the positioning strips 304 and the T-slots 1101, ensuring that the distribution of each segment in the circumferential direction is uniform and the angle is accurate.

[0038] The top of the rotary spindle 301 is provided with a centering shaft 305 for mounting several segmented stators 11. The segmented stators 11, after being arranged into a circle, are inserted from above the centering shaft 305. The centering shaft 305 is rotatably connected to the top of the pusher shaft 306 via bearings to ensure that the rotary spindle 301 can smoothly drive the segmented stators 11 and the centering shaft 305 to rotate simultaneously. The outer diameter of the centering shaft 305 is adapted to the inner diameter of the segmented stators 11, which can radially center the stator assembly and ensure that the inner circle of all segmented stators 11 is coaxial with the rotary spindle 301, significantly improving the roundness of the stators.

[0039] The rotary spindle 301 has a through groove extending through its upper and lower ends. A pusher shaft 306 is slidably connected in the through groove. It also includes a seventh drive component (specifically a prior art cylinder, the drive and installation methods of which are prior art and will not be described in detail in this embodiment) for driving the pusher shaft 306 to rise and fall.

[0040] The clamping assembly radially clamps each segment of the stator 11 from the outside, so that its inner wall fits tightly against the outer wall of the centering shaft 305. After welding, each segment of the stator 11 forms a stable annular whole under the action of the clamping force and is tightly fitted onto the centering shaft 305. At this time, the seventh drive component drives the pusher shaft 306 to rise, which can lift the welded segment of the stator 11 together with the centering shaft 305 to achieve automatic unloading.

[0041] A mounting plate 307 is sleeved and fixedly connected to the rotary spindle 301. The clamping assembly includes a sliding block 308 disposed on the mounting plate 307. The mounting plate 307 is provided with a guide rail for the sliding block 308 to slide on. The sliding block 308 is slidably connected to the surface of the mounting plate 307 in a radial direction. A clamping block 309 is provided at the end of the sliding block 308 facing the segmented stator 11. The end of the clamping block 309 is an arc-shaped concave surface that fits against the outer wall of the segmented stator 11. The assembly also includes an eighth driving component (using an existing motor and lead screw mechanism, which will not be described in detail in this embodiment) for driving the sliding block 308 to move closer to or away from the corresponding segmented stator 11. Each segmented stator 11 corresponds to an independent clamping assembly, and the clamping force can be adjusted individually as needed.

[0042] Two sets of welding components are provided and are respectively located on both sides of the positioning component. The welding components are existing technology and will not be described in detail in this embodiment. When the rotary spindle 301 drives the stator component to rotate at the indexing point, the two sets of welding components can simultaneously weld the two splice seams that are in symmetrical positions, thereby halving the number of welding operations required to complete all weld seams and significantly improving production efficiency.

[0043] like Figure 11 and 12As shown, the outer diameter detection mechanism 4 includes a first material rack 401 disposed on the surface of the workbench. The first material rack 401 includes a material plate 402, and a first material seat 403 is rotatably connected to the surface of the material plate 402. It also includes a ninth driving member for driving the material plate 402 to rise and fall and a tenth driving member for driving the first material seat 403 to rotate (the ninth and tenth driving members are both prior art and will not be described in detail in this embodiment). First detection elements are respectively disposed on both sides of the first material rack 401, and second detection elements are respectively disposed on the other two sides of the workbench 1 located on the surface of the first material rack 401.

[0044] When the outer diameter detection mechanism 4 detects a deviation in the position of the segmented stator 11 at the corresponding position, the system adjusts the corresponding clamping component to compensate for the positioning accuracy of the segmented stator 11 in subsequent processing batches by adjusting the clamping force of the corresponding clamping component or adjusting the stroke parameters of the third drive component according to the detected deviation value.

[0045] The first detection component includes a fourth support rod 404 disposed on the surface of the workbench 1. A fourth support plate 405 is disposed at the top of the fourth support rod 404. A sliding plate 406 and an eleventh driving component for driving the sliding plate 406 are slidably connected to the surface of the fourth support plate 405. A GT sensor 407 is disposed on the sliding plate 406, with its probe end facing the first material seat 403. The eleventh driving component is specifically a cylinder, which is used to drive the two GT sensors 407 to approach each other and detect the diameter of the segmented stator 11.

[0046] A fifth support plate 408 is provided at the opposite ends of the two sliding plates 406. Sliding rods 409 are slidably connected through both ends of the fifth support plate 408. An abutment rod 410 is fixedly connected between the ends of the two sliding rods 409 facing the first material seat 403. A second spring 411 is sleeved and fixedly connected between the sliding rods 409 and the abutment rod 410. A through hole is opened in the middle of the fifth support plate 408 for the probe of the GT sensor 407 to pass through.

[0047] When the eleventh driving member of the two sets of first detection elements drives the corresponding sliding plate 406 to move towards the first material seat 403, the two abutting rods 410 first abut against the opposite sides of the outer wall of the segmented stator 11. The eleventh driving member continues to push the sliding plate 406. At this time, the sliding rod 409 remains stationary because the abutting rod 410 has contacted the stator, and the fifth support plate 408 continues to move along the sliding rod 409. The second spring 411 set between the fifth support plate 408 and the abutting rod 410 is further compressed. When the probe end of the GT sensor 407 just contacts the detection surface of the abutting rod 410, the eleventh driving member stops moving. At this time, the displacement measured by the GT sensor 407 is the extension length of the probe. Combining the total extension length of the probes on both sides with the difference between the initial distance between the two abutting rods 410, the outer diameter of the segmented stator 11 in this radial direction can be calculated. By rotating the first material placement seat 403, point-by-point measurements can be taken at multiple positions along the circumference of the segmented stator 11 to obtain complete outer diameter distribution data. After the test is completed, the eleventh driving component drives the sliding plate 406 to reset, and the abutment rod 410 and the sliding rod 409 reset under the elastic force of the second spring 411.

[0048] The second detection component includes fifth support rods 412 disposed on the surface of the workbench 1 and located on both sides of the first material rack 401. A distance sensor 413 is mounted on the top of each fifth support rod 412. The two distance sensors 413 are arranged opposite each other along a diameter direction of the first material rack 403, and their connecting line passes through the rotation center of the first material rack 403.

[0049] The first and second detection elements are respectively disposed on two opposite sides of the first material rack 401, and their measurement directions are perpendicular to each other. The first detection element is a contact-type GT sensor 407 used to measure the diameter of the segmented stator 11 in a certain radial direction; the second detection element is a non-contact distance sensor 413 used to measure the diameter of the segmented stator 11 in another radial direction perpendicular to it. When the segmented stator 11 is rotated by the tenth drive element, the first and second detection elements can simultaneously collect diameter data in their respective directions, eliminating the need for separate measurements. Diameter values ​​in two mutually perpendicular directions can be obtained with a single rotation, thereby accurately assessing the stator's roundness and outer diameter consistency, while significantly improving detection efficiency.

[0050] like Figure 13As shown, a vision inspection mechanism 7 is also provided on the surface of the workbench 1 at the tail end of the conveyor support 501. The vision inspection mechanism 7 includes a second material rack 701, a second material seat 702 and a twelfth driving component (the twelfth driving component is a cylinder, which will not be described in detail in this embodiment) for driving the second material seat 702 to rise and fall. A mounting frame 703 is provided on one side of the workbench 1 at the second material rack 701. A camera 704 and a supplementary light source 705 are mounted on the mounting frame 703.

[0051] After welding, defects such as porosity and cracks may exist in the weld seams at the joints of the segmented stator 11. High-definition images of the weld seam area are acquired by camera 704 in conjunction with supplementary lighting source 705, and defects are automatically identified using image processing algorithms. This enables online inspection of the weld seam appearance quality, replacing traditional manual visual inspection and significantly improving inspection efficiency and consistency.

[0052] like Figure 13 and Figure 14 As shown, the workbench 1 has a third material rack 801 and a fourth material rack 101 arranged side by side with the second material rack 701. An inner diameter detection mechanism 8 is provided on one side of the workbench 1 located on the third material rack 801. A third material rack 802 is provided on the surface of the third material rack 801. The inner diameter detection mechanism 8 includes a detection bracket 803 provided on one side of the third material rack 801, a go gauge 804 slidably connected to the detection bracket 803, and a sixteenth driving member for driving the go gauge 804 to rise (the sixteenth driving member is a cylinder of the prior art, which will be described in detail in this embodiment). The outer diameter of the go gauge 804 is adapted to the lower limit dimension of the inner diameter of the segmented stator 11 and is used to insert into the inner hole of the segmented stator 11 to determine whether the inner diameter is qualified.

[0053] A secondary conveying mechanism 9 is provided on one side of the workbench 1, located on the surface of the second material rack 701, the third material rack 801, and the fourth material rack 101. The secondary conveying mechanism 9 includes a sliding seat 901 slidably connected to the surface of the workbench 1 along the arrangement direction of the second material rack 701, the third material rack 801, and the fourth material rack 101, and a thirteenth driving member (the thirteenth driving member is a prior art cylinder, which will be described in detail in this embodiment) for driving the sliding seat 901. An L-shaped bracket 902 is slidably connected to the surface of the sliding seat 901 along a direction perpendicular to its own sliding direction, and a fourteenth driving member (the fourteenth driving member is a prior art cylinder) for driving the L-shaped bracket 902. (This embodiment will not be described in detail here). The L-shaped bracket has a vertically slidable unloading gripper 903 (the unloading gripper 903 is a conventional pneumatic gripper, which will not be described in detail here) on one side of the L-shaped bracket facing the second, third, and fourth material racks 701 and 801. It also includes a fifteenth driving component (the fifteenth driving component is a conventional cylinder, which will be described in detail here) for driving the unloading gripper 903 to rise and fall. There are two sets of unloading grippers 903. While transferring the segmented stator 11 on the second material rack 702 to the third material rack 802, it also transfers the segmented stator 11 on the third material rack 802 to the fourth material rack to improve the transfer efficiency.

[0054] like Figure 1 As shown, a feeding mechanism 10 is provided on one side of the fourth material rack (101) on the surface of the workbench 1. The structure of the fourth material rack 101 is the same as that of the third material rack, and will not be described in detail in this embodiment. Its structure and driving method are the same as those of the inner clamping claw 503 in the first-level conveying mechanism 5, and will not be described in detail in this embodiment. A finished product rack 102 is also provided on one side of the workbench 1. The feeding mechanism 10 is used to transfer the segmented stator 11 on the fourth material rack 101 to the finished product rack 102, thereby completing the processing and inspection of the segmented stator 11.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
