[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1 to 4As shown, an automatic reel welding device includes a machine base 10, a positioning mechanism 20, a flipping mechanism 30, a carrying mechanism 40, a material transfer mechanism 50, and an ultrasonic welding mechanism 60. The positioning mechanism 20 includes a support plate 21 and an adjustment component 22. The adjustment component 22 abuts against the workpiece 100 placed on the support plate 21 and drives it to rotate horizontally. The material transfer mechanism 50 includes a moving module 51 and a first suction cup 52 disposed on the moving module 51. The first suction cup 52 is provided with a first suction hole (not shown) for adsorbing the workpiece 100 located on the positioning mechanism 20. The flipping mechanism 30 includes a rotating table 31 and a second suction cup 30 disposed on the rotating table 31. 2. The second suction cup 32 is provided with a second suction hole 321 for adsorbing the workpiece 100 fed by the transfer mechanism 50 (first suction cup 52). The carrying mechanism 40 includes a translation module 41 and a positioning plate 42 disposed on the translation module 41. The translation module 41 can be a pen-shaped cylinder. After being driven by the translation module 41 to approach the flipping mechanism 30, the positioning plate 42 is used to carry the workpiece 100 in a flipped state fed by the flipping mechanism 30, and to carry the unflipped workpiece 100 fed by the transfer mechanism 50 so that it is engaged with the workpiece 100 in a flipped state. The ultrasonic welding mechanism 60 is disposed on the machine base 10 for welding a pair of workpieces 100 in an engaged state.

[0027] In this invention, the workpiece 100, with its front side 100A facing upwards, can be placed on the support plate 21 manually or by a robotic arm. The support plate 21 has a first clearance hole 210 to accommodate the semi-ring 101 on the back side 100B of the workpiece 100. Simultaneously, the workpiece 100 interacts with the adjustment component 22 while on the support plate 21. The adjustment component 22 rotates the workpiece 100 on the support plate 21 until it reaches a set posture, completing the initial positioning of the workpiece 100. The moving module then... 51 drives the first suction cup 52 to move to the positioning mechanism 20 to adsorb the front side 100A of the workpiece 100, and feeds the workpiece 100 in this posture to the flipping mechanism 30, that is, place it on the second suction cup 32. The second suction cup 32 is provided with a second clearance hole 320, which can accommodate the semi-ring 101 on the reverse side 100B of the workpiece 100. The first suction cup 52 de-adsorbs and the second suction cup 32 adsorbs the reverse side 100B of the workpiece 100. The translation module 41 drives the positioning plate 42 to move close to the flipping mechanism 30. At this point, the rotary table 31 drives the second suction cup 32 to rotate the workpiece 100 180° in the vertical plane, so that the workpiece 100, with its reverse side 100B facing upwards (i.e., the semi-ring 101 facing upwards), abuts against the positioning plate 42. The second suction cup 32 releases and resets. At the same time, another workpiece 100, positioned by the positioning mechanism 20, is attracted by the first suction cup 52 with its front side 100A facing upwards, and is then moved and fed to the workpiece 100 with its reverse side 100B facing upwards on the positioning plate 42, realizing the two... The two workpieces 100 are fastened together, and the two semi-ring parts 101 on the two workpieces 100 form a ring. The first suction cup 52 is released, and the translation module 41 drives the positioning plate 42 and the pair of fastened workpieces 100 to move below the ultrasonic welding mechanism 60. The ultrasonic welding mechanism 60 can weld the semi-ring part 101 on one workpiece 100 to the other workpiece 100, thereby completing the forming of the entire reel. Then, the carrying mechanism 40 can send the reel out, and it can be unloaded manually or by the material transfer mechanism 50. It should be noted that when fastening a pair of workpieces 100 together, the matching plug-in 103 formed on the workpieces 100 can be inserted to prevent the two from shifting and to achieve a certain degree of connection stability.

[0028] This invention first uses a positioning mechanism 20 to pre-position the workpiece, then places one positioned workpiece 100 onto the bearing mechanism 40 with its reverse side 100B facing upwards after being transferred and flipped. Another positioned workpiece 100 is then transferred and directly fastened to the workpiece 100 with its front side 100A facing upwards. The workpiece is then moved to the underside of the ultrasonic welding mechanism 60 for welding and forming a reel. The above processes work together to achieve automatic positioning, transfer, flipping, fastening and welding, improving the automation level and efficiency of welding.

[0029] Continue as Figure 2As shown, the adjustment assembly 22 includes a rotary cylinder 221, a first positioning post 222, and three first positioning teeth 223. The first positioning post 222 is mounted on the rotary cylinder 221, and the three first positioning teeth 223 are mounted on the side wall of the first positioning post 222. Figure 4 As shown, since a half-shaft 102 is provided on the reverse side 100B of the workpiece 100, and a through hole 1020 is provided on the half-shaft 102 to pass through its body and the workpiece 100, and a slot 1021 is provided on the side wall of the through hole 1020, when a pair of workpieces 100 are engaged, a pair of through holes 1020 on a pair of half-shafts 102 are connected, and the corresponding slots 1021 are connected. When the workpiece 100 is placed on the support plate 21, the through hole 1020 is also fitted onto the first positioning post 222 by manual or robotic arm, and the slot 1021 is fitted onto the first positioning tooth 223. Therefore, the first positioning post 222 can be driven to rotate by the rotary cylinder 221 to drive the workpiece 100 to rotate to the set posture.

[0030] The moving module 51 in the material transfer mechanism 50 includes a horizontal module 511 and a vertical module 512. The horizontal module 511 is mounted on the machine base 10, and the vertical module 512 is mounted on the horizontal module 511. The first suction cup 52 is mounted on the vertical module 512. Therefore, the first suction cup 52 can be driven to move in the horizontal and vertical directions within the vertical plane to transfer the workpiece 100.

[0031] like Figure 3 As shown, the flipping mechanism 30 also includes an auxiliary bearing 34. The side of the second suction cup 32 away from the rotary table 31 is rotatably disposed in the auxiliary bearing 34 to ensure stable support for the second suction cup 32 so as to achieve its stability during the flipping process.

[0032] In addition, the positioning plate 42 is provided with a second positioning post 43. The second positioning post 43 has a structure similar to the first positioning post 222, that is, the second positioning post 43 is provided with three second positioning teeth (not shown). When the workpiece 100 is flipped and placed on the positioning plate 42 with its front 100A facing down, its through hole 1020 and slot 1021 are respectively fitted onto the second positioning post 43 and the second positioning teeth, which can ensure the stability of the workpiece 100 when the positioning plate 42 moves. The interlocking pair of workpieces 100 are kept in a stable position by the interaction between the plug-in 103.

[0033] Based on the configuration of the second positioning post 43 and the second positioning tooth, in order to ensure that the workpiece 100 can be smoothly placed on the positioning plate 42 at the end of the flipping process, the upper end of the second positioning tooth is provided with a chamfer on the side away from the second positioning post 43.

[0034] To ensure the stability of the movement of the positioning plate 42, the bearing mechanism 40 also includes a guide assembly, which includes a slider 441 and a guide rod 442. The slider 441 is disposed on the positioning plate 42, and the guide rod 442 is disposed on the machine base 10. The slider 441 is slidably disposed on the guide rod 442.

[0035] The machine base 10 is provided with a first buffer 33 that can abut against the second suction cup 32, which can be used to support the second suction cup 32 when it is not flipped; the machine base 10 is also provided with a second buffer 45 that can abut against the positioning plate 42 to prevent the positioning plate 42 from vibrating at the moving end.

[0036] The machine base 10 is provided with a feeding hole 10a. Below the feeding hole 10a, the machine base 10 is provided with a feeding mechanism 70 for carrying the welding and feeding reel of the material after transfer mechanism 50. The feeding mechanism 70 can be in the form of a conveyor line or a combination of pallet receiving and cylinder pushing. In addition, a scrap hole 80 can be provided on the machine base 10 next to the positioning mechanism 20, so that workpieces 100 with defects in appearance can be placed in the scrap hole 80.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
