Description

Technical Field

[0001] The utility model relates to the technical field of coil welding, in particular to an alternating motor coil welding mechanism. Background Art

[0002] A coil typically refers to a ring-shaped winding of wire. Common coil applications include motors, inductors, transformers, and loop antennas. It's typically made by winding wires one by one, insulating them from each other. Motor coils are made by splicing together multiple stators, which then need to be welded to a welding machine. However, in existing technology, when the motor coils are transferred to the welding station for welding, the coils are not yet welded, and the multiple stators are connected by a clip-on structure that allows for vertical movement. This makes it difficult to maintain the stator's proper position during transfer, and the subsequent welding accuracy cannot be guaranteed. Utility Model Content

[0019] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0020] like Figures 1 to 5 , which is a schematic structural diagram of the alternating motor coil welding mechanism provided by the present invention. The alternating motor coil welding mechanism includes a frame 10, an alternating assembly 20 disposed on the frame 10, two pressing assemblies 30 disposed on the frame 10, a buffer assembly 40 disposed on the frame 10, a rotating assembly 50 disposed on the frame 10, and a welding assembly 60. It is conceivable that the alternating motor coil welding mechanism also includes other functional modules, such as connecting assemblies, fasteners, and mounting assemblies, etc., which are well known to those skilled in the art and will not be described in detail here.

[0021] The rack 10 is used to carry the above-mentioned functional modules, so the rack 10 is provided with a variety of functional structures, such as screws, bolts, clamps, etc. to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs and will not be described in detail here.

[0022] The alternating assembly 20 includes a first driving device 21 disposed on the frame 10, a mounting plate 22 disposed on the first driving device 21, two limiting cylinders 23 disposed on the mounting plate 22, and two fixing cylinders 24 respectively disposed in the limiting cylinders 23.

[0023] The output end of the first drive device 21 is connected to the center of the mounting plate 22. The first drive device 21 comprises a rotary motor and a drive cylinder, and is used to drive the mounting plate 22 to move up and down and rotate to interchange the positions of the two ends. The first drive device 21 is known from the prior art and will not be described in detail here.

[0024] Through holes 221 are provided at both ends of the mounting plate 22 to facilitate the insertion of the pressing assembly 30 and the buffer assembly 40 into the fixed cylinder 24. Avoidance openings 222 are provided on both sides of the through hole 221. The avoidance openings 222 are used to set the rotating assembly 50 to rotate the fixed cylinder 24. The specific description will be given below in conjunction with the rotating assembly 50. The limiting cylinder 23 is used to limit the position of the fixed cylinder 24. The fixed cylinder 24 is coaxially arranged with the through hole 221. The fixed cylinder 24 is used to set the coil, so a slot for engaging with the coil is provided on its inner side wall. A plurality of welding holes 25 are provided at intervals on the side wall of the fixed cylinder 24. When the coil is placed in the fixed cylinder 24, the gap between the plurality of stators is just within the welding hole 25, so that the welding assembly 60 can weld the gap between the two stators through the welding hole 25.

[0025] The pressing assembly 30 includes a first linear drive device 31 provided on the frame 10, and a pressing cylinder 32 provided on the first linear drive device 31. The first linear drive device 31 is used to drive the pressing cylinder 32 to move vertically. The diameter of the pressing cylinder 32 is the same as the diameter of the coil, so that the pressing cylinder 32 can press the upper end surface of the coil. The two pressing assemblies 30 are respectively located above the buffer assembly 40 and the rotating assembly 50, wherein the pressing assembly 30 located above the buffer assembly 40 is also provided with a placement platform assembly 70, and the placement platform assembly 70 includes four guide posts 71 and a placement plate 72 provided on the guide posts 71. One end of the four guide posts 71 is movably provided through the frame 10 and connected to the external drive device, and the other end is connected to the placement plate 72. The center of the placement plate 72 is provided with a placement hole 73. The coil to be welded will be placed in a jig and transported into the placement hole 73 by a mechanical claw or manually. The specific working method will be described below in conjunction with the buffer assembly 40.

[0026] The buffer assembly 40 includes a second linear drive device 41 arranged on the frame 10, a disc 42 arranged on the first linear drive device 31, a cylinder 43 arranged on the disc 42, a plurality of slide grooves 44 spaced apart on the outer wall of the cylinder 43, a plurality of buffer columns 45 slidingly arranged in the slide grooves 44, and a plurality of springs 46 arranged on the buffer columns 45.

[0027] The second linear drive device 41 is used to drive the disc 42 to move vertically. The disc 42 has a boss at its center to accommodate the cylinder 43, so that the cylinder 43 is spaced apart from the disc 42 to provide installation space and compression distance for the spring 46. The cylinder 43 is coaxially arranged with the fixed cylinder 24. The two ends of the chute 44 are connected to the two ends of the disc 42. One end of the buffer column 45 extends out of the chute 44 and is provided with a stopper 451 and a latch 452 disposed on the stopper 451. The other end abuts the bottom of the coil. Each buffer column 45 abuts against a stator. The limiting portion 451 abuts against one end of the chute 44 toward the disc 42, the latch 452 is movably inserted on the disc 42, the spring 46 is sleeved on the latch 452, one end of the spring 46 abuts against the disc 42, and the other end abuts against the limiting portion 451, and pushes the buffer column 45 toward the direction of the pressing assembly 30 through its own elastic force, so that one end of the buffer column 45 extends out of the chute 44. When in use, first, a jig with a coil is placed on the center of the placement plate 72 manually or by a robot, and then the buffer assembly 40 rises so that the multiple buffer columns 45 abut against the bottom of the coil, and at the same time, the pressing assembly 30 descends so that the pressing cylinder 32 presses the top of the coil. At this time, the buffer column 45 is subjected to force to compress the spring 46, and the spring 46's own elastic force causes the buffer column 45 to push the stator toward the lower pressure cylinder 32. Since the coil has not yet been welded, the multiple stators are connected by a mutual clamping structure and can move vertically, thereby ensuring that the multiple stators of the coil are flush with the lower pressure cylinder 32, ensuring the accuracy of the coil position during subsequent welding. Then, the buffer assembly 40 and the lower pressure assembly 30 move downward simultaneously to clamp the coil and send it into the fixed cylinder 24. During the transfer process, the buffer assembly 40 can also ensure the flushness of the stator and the accuracy of the coil position.

[0028] The rotating assembly 50 includes a second driving device 51 , a rotating plate 52 disposed on the second driving device 51 , two protrusions 53 disposed at both ends of the rotating plate 52 , and two connecting pins 54 disposed on the protrusions 53 .

[0029] The bottom of the fixed cylinder 24 is provided with a socket that mates with the connecting pin 54. During use, the alternating assembly 20 exchanges the pressed coil to the upper portion of the rotating assembly 50. The second drive device 51 then drives the rotating plate 52 upward, inserting the connecting pin 54 into the fixed cylinder 24 and lifting the fixed cylinder 24. Simultaneously, the welding assembly 60 welds the gaps between the stators. After completing one weld, the second drive device 51 drives the rotating plate 52 to rotate one station, and the welding assembly 60 welds the next gap, repeating this process for all gaps. During welding, the fixed cylinder 24 at the buffer assembly 40 is left empty, allowing for unloading, thereby alternating work to improve efficiency.

[0030] Compared with the prior art, the alternating motor coil welding mechanism provided by the present invention can neatly transfer the unwelded coils into the fixed cylinder 24 through the buffer assembly 40 and the press-down assembly 30. A plurality of slide grooves 44 are provided on the outer wall of the cylinder 43, one end of the buffer column 45 extends out of the slide groove 44 and is provided with a limiting portion 451 and a latch 452 provided on the limiting portion 451, and the other end abuts against the bottom of the coil, and each of the buffer columns 45 abuts against one of the stators. One end of the spring 46 abuts against the disc 42, and the other end abuts against the limiting portion 451. When the buffer assembly 40 and the press-down assembly 30 clamp the coil, the spring 46 will push the buffer column 45 to push the stator toward the press-down cylinder 32, so that multiple stators fit flush against the press-down cylinder 32, ensuring the accuracy of the coil position during subsequent welding. At the same time, the alternating assembly 20 can control the two fixed cylinders 24 to exchange positions, so that both sides can perform corresponding work at the same time, ensuring work efficiency.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
