[0002] In recent years, artificial intelligence technology has developed rapidly, and important achievements such as large language models, autonomous driving, and video generation have continued to emerge. As AI technology is increasingly used in all walks of life, artificial intelligence has become an important driving force for a new round of scientific and technological revolution and industrial transformation. The key to supporting the rapid development of artificial intelligence technology lies in the large-scale production and application of AI servers with high-performance computing capabilities and large-capacity storage space, which has led to a significant increase in the demand for inductors related to AI servers.

[0003] In the automated production of AI server inductors, the pin forming process of the inductor is a difficult technical problem to overcome. It involves bending the inductor pins in multiple directions or multiple times.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The automated pin forming intelligent manufacturing all-in-one machine for AI server inductors provided by the present invention straightens the pins of the inductor horizontally through a pin straightening mechanism. When the pins of the inductor are made of a slender and soft metal material such as copper wire, the pins of the inductor are prone to bending and deformation during storage and transportation. Therefore, the pins of the inductor need to be straightened horizontally by the pin straightening mechanism first to ensure the processing accuracy of subsequent processes.

[0031] 2. After the inductor pins are straightened, the pins of the inductor need to be processed from a horizontally straightened state to an L-shaped structure through a pin pre-bending mechanism. The limiting bottom mold of the pre-bending lower mold assembly is used to support the pins of the inductor from below, the pre-bending upper mold of the pre-bending upper mold assembly is used to press the pins of the inductor from above, and the first upper bending punch is used to bend the pins of the inductor upward to the pin limiting groove of the pre-bending upper mold, so that a part of the inductor pin (called the upper folding part) can be bent to the pin limiting groove, and the other part of the pin (called the root) is clamped between the limiting bottom mold and the pre-bending lower mold, and still maintains a horizontally straightened state; through the limiting effect of the pin limiting groove on the upper folding part, and the limiting effect of the limiting bottom mold and the pre-bending upper mold on the root, when the first upper bending punch bends the inductor pin upward, it can accurately bend the pin from a horizontally straightened state to an L-shaped structure.

[0032] 3. After the pins of the inductor are processed into an L-shaped structure, they need to be bent in multiple directions through a pin multi-directional bending mechanism; the second upper bending die is used to bend the root of the pin upward, which makes the upper folded part of the pin tilt in the direction of the pin limiting channel, and then the upper folded part enters the pin limiting channel and is under the lower bending plate, and then the pin is pressed against the side of the inductor housing through the side pressure die, and finally through the lower bending plate of the lower bending die, the lower bending plate moves down along the pin limiting channel, and then the pin is accurately pressed down to the preset position at the upper end of the inductor housing.

[0033] 4. The automatic pin forming intelligent manufacturing all-in-one machine of the present invention is used to realize the automated production of inductor pin forming; through pin forming mechanisms such as pin straightening mechanism, pin pre-bending mechanism and pin multi-directional bending mechanism, the bending of the inductor pin can be accurately controlled to prevent erroneous deformation, thereby improving the yield and production efficiency of the inductor device.

[0080] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0082] The workpiece conveying mechanism 1 of this embodiment is used to convey the inductor to each pin forming mechanism in sequence for processing. Figure 3 and Figure 4 The workpiece conveying mechanism 1 can adopt a turntable mechanism that conveys the workpiece (i.e., the inductor) by rotating the turntable 11, and a plurality of positioning fixtures 12 arranged in a circle are arranged on the turntable 11 of the workpiece conveying mechanism 1. The turntable 11 is formed with avoidance openings 13 on both sides of each positioning fixture 12. The avoidance openings 13 are used for the relevant upper mold components of the pin forming mechanism to pass through, so as to facilitate the processing of the inductor; the positioning fixture 12 is provided with a positioning groove 123 with an opening facing upward and used to place the inductor. Specifically, the positioning fixture 12 includes a main body 121 and mounting parts 122 located at both ends of the main body 121, and the positioning groove 123 is provided on the main body 121; the workpiece conveying mechanism 1 provides the power for the turntable 11 to rotate through the turntable driving device 14. The turntable mechanism is adopted, and the feeding mechanism 2, each pin forming mechanism, the unloading mechanism 9, etc. are arranged around the turntable 11, which can improve the space utilization rate and reduce the overall volume of the integrated machine.

[0083] refer to Figure 5 The feeding mechanism 2 of this embodiment includes a feeding conveying assembly 21, a feeding guide rail 22, and a feeding fixture 23 assembled on the feeding guide rail 22. The feeding fixture 23 is used to grab the inductor to be processed from the feeding conveying assembly 21 to the positioning fixture 12 of the workpiece conveying mechanism 1. Fig.34 The unloading mechanism 9 of this embodiment includes an unloading tray assembly 91, an unloading guide rail 92, and an unloading fixture 93 assembled on the unloading guide rail 92. The unloading fixture 93 is used to grab the processed inductor from the workpiece conveying mechanism 1 to the unloading tray assembly 91. In this embodiment, the loading mechanism 2 realizes the loading of the inductor to be processed, and the unloading mechanism 9 realizes the unloading of the processed inductor.

[0084] refer to Figure 6-Figure 9The pin straightening mechanism 3 of this embodiment includes a straightening mechanism frame 31, a straightening mechanism upper mold cylinder 32, a straightening mechanism lower mold cylinder 33, a pin straightening upper mold assembly 34 and a pin straightening lower mold assembly 35 arranged below the pin straightening upper mold assembly 34. The straightening mechanism frame 31 is provided with a straightening mechanism lifting guide rail 36. The straightening mechanism upper mold cylinder 32 and the straightening mechanism lower mold cylinder 33 are installed on the straightening mechanism frame 31. The pin straightening upper mold assembly 34 and the pin straightening lower mold assembly 35 are slidably assembled on the straightening mechanism lifting guide rail 36. The straightening mechanism upper mold cylinder 32 is used to drive the pin straightening upper mold assembly 34 to move up and down, and the straightening mechanism lower mold cylinder 33 is used to drive the pin straightening lower mold assembly 35 to move up and down.

[0085] The pin straightening upper mold assembly 34 includes a straightening mechanism upper mold base 341, a straightening mechanism limiting upper mold 342 and a straightening mechanism buffer ejector pin 343 assembled on the straightening mechanism limiting upper mold 342. The straightening mechanism upper mold base 341 is connected to the piston end of the straightening mechanism upper mold cylinder 32, the straightening mechanism limiting upper mold 342 is fixedly connected to the straightening mechanism upper mold base 341, and the bottom end of the straightening mechanism limiting upper mold 342 is provided with limiting plates 3421 on both sides of the straightening mechanism buffer ejector pin 343. The upper side of the straightening mechanism buffer ejector pin 343 is equipped with a buffer, and the bottom end of the straightening mechanism buffer ejector pin 343 extends to the bottom of the straightening mechanism limiting upper mold 342. Among them, the straightening mechanism buffer ejector pin 343 is mainly used to press the upper end of the inductor during the processing to maintain the stability of the inductor. Because the positioning groove 123 of the positioning fixture 12 does not limit the upper end of the inductor, the straightening mechanism buffer ejector pin 343 is needed to play such a role. In addition, the buffer can adopt a retractable device of spring or air pressure type, the straightening mechanism limiting upper mold 342 can adopt a hollow structure to form an assembly groove, the straightening mechanism buffer ejector pin 343 and its buffer can be assembled in the assembly groove of the straightening mechanism limiting upper mold 342, the upper end of the buffer is limited by the bottom end of the straightening mechanism upper mold base 341 or the top end of the straightening mechanism limiting upper mold 342, and the lower end of the buffer is limited by the straightening mechanism buffer ejector pin 343. In this way, when the straightening mechanism buffer ejector pin 343 presses the inductor and the straightening mechanism upper mold cylinder 32 continues to drive the pin straightening upper mold assembly 34 downward, the straightening mechanism buffer ejector pin 343 will compress the buffer and the straightening mechanism limiting upper mold 342 moves downward relative to the straightening mechanism buffer ejector pin 343.

[0086] The pin straightening lower die assembly 35 includes a straightening mechanism lower die base 351, a straightening cylinder 352, and straightening dies 353 arranged on both sides of the straightening mechanism buffer ejector pin 343.

The straightening cylinder 352 is installed on the straightening mechanism lower die base 351.

[0105] refer to Figure 23-Figure 31The pin multi-directional bending mechanism 7 of this embodiment includes a multi-directional bending mechanism frame 71, a multi-directional bending mechanism upper die cylinder 72, a multi-directional bending mechanism lower die cylinder 73, a multi-directional bending upper die assembly 74 and a multi-directional bending lower die assembly 75 arranged below the multi-directional bending upper die assembly 74. The multi-directional bending mechanism frame 71 is provided with a multi-directional bending mechanism lifting guide rail 76. The multi-directional bending mechanism upper die cylinder 72 and the multi-directional bending mechanism lower die cylinder 73 are installed on the multi-directional bending mechanism frame 71. The multi-directional bending upper die assembly 74 and the multi-directional bending lower die assembly 75 are slidably assembled on the multi-directional bending mechanism lifting guide rail 76. The multi-directional bending mechanism upper die cylinder 72 is used to drive the multi-directional bending upper die assembly 74 to move up and down. The multi-directional bending mechanism lower die cylinder 73 is used to drive the multi-directional bending lower die assembly 75 to move up and down.

[0106] The multi-directional bending upper die assembly 74 includes an upper die base 741 of a multi-directional bending mechanism, a lower bending cylinder 742, a buffer ejector pin 745 of a multi-directional bending mechanism, a mounting block 746, a lower bending punch 743 and a limiting fork 744 assembled on both sides of the lower bending punch 743. The cylinder body of the lower bending cylinder 742 is fixed to the upper end of the upper die base 741 of the multi-directional bending mechanism, the piston end of the lower bending cylinder 742 is coaxially connected to the piston end of the upper die cylinder 72 of the multi-directional bending mechanism, the upper end of the mounting block 746 is fixed to the upper die base 741 of the multi-directional bending mechanism, the lower end of the mounting block 746 is fixed to the lower bending punch 743, the upper side of the buffer ejector pin 745 of the multi-directional bending mechanism is assembled with a first buffer, and the upper side of the limiting fork 744 is assembled with a second buffer. Among them, the first buffer can adopt a retractable device of spring or air pressure type, the multi-directional bending mechanism buffer ejector pin 745 and its first buffer can be assembled in the assembly groove on the inner side of the mounting block 746, the upper end of the first buffer is limited by the bottom end of the multi-directional bending mechanism upper mold base 741 or the top end of the mounting block 746, and the lower end of the first buffer is limited by the multi-directional bending mechanism buffer ejector pin 745.

[0107] In the multi-directional bending upper die assembly 74, lower bending plates 7431 are fixed on both sides of the lower bending punch 743, and the lower bending plates 7431 are located between the two fork teeth 7441 of the limiting fork 744, and a pin limiting channel 7442 is formed between the two fork teeth 7441 of the limiting fork 744. The lower bending punch 743 is provided with an assembly through hole 7432, and the lower bending plates 7431 and the assembly through holes 7432 are arranged in a staggered manner. The fork teeth 7441 of the limiting fork 744 pass through the assembly through hole 7432, and the fork teeth 7441 extend to the bottom of the lower bending punch 743, and the multi-directional bending mechanism buffer ejector pin 745 passes through the bottom end of the lower bending punch 743, and the bottom end of the multi-directional bending mechanism buffer ejector pin 745 extends to the bottom of the limiting fork 744.

[0108] In the multi-directional bending upper die assembly 74, the lower bending cylinder 742 is used to drive the lower bending die 743 to move downward relative to the limiting fork 744, and then the lower bending plate 7431 moves downward relative to the fork teeth 7441, so that the lower bending plate 7431 can perform a lower bending process on the inductor pin. In order to ensure that the lower bending cylinder 742 can indeed drive the lower bending die 743 to move downward relative to the limiting fork 744, the design adopted in this embodiment is to assemble a second buffer on the upper side of the limiting fork 744, and the upper and lower ends of the second buffer are respectively limited by the mounting block 746 and the limiting fork 744. In this design, when the fork teeth 7441 of the limiting fork 744 abut against the inductor, the second buffer can be compressed, and then the lower bending die 743 can move downward relative to the limiting fork 744 under the drive of the lower bending cylinder 742. Of course, other embodiments may also be adopted. For example, the lower bending cylinder 742 and the lower bending die 743 may be connected in a manner similar to that of the upper bending cylinder 553 and the first upper bending die 554. That is, there is no need to add an additional buffer, and the piston end of the cylinder is directly connected to the die. In this way, the lower bending die 743 can be moved downward relative to the limit fork 744.

[0109] The multi-directional bending lower die assembly 75 includes a multi-directional bending mechanism lower die base 751, a second upper bending die 752, a side pressure cylinder 753, and side pressure dies 754 arranged on both sides of the second upper bending die 752. The side pressure cylinder 753 is used to drive the side pressure die 754 to move laterally. The multi-directional bending mechanism lower die base 751 is connected to the piston end of the multi-directional bending mechanism lower die cylinder 73. The side pressure cylinder 753 is fixedly mounted on the multi-directional bending mechanism lower die base 751, and the second upper bending die 752 is fixedly mounted on the side pressure cylinder 753. Since a side pressure die 754 needs to be arranged on both sides of the second upper bending die 752, in order to realize the opening and closing action of the two side pressure dies 754, the side pressure cylinder 753 can adopt a parallel opening and closing type double-claw cylinder, or it can be realized by two single-output cylinders.

[0110] In the multi-directional bending lower die assembly 75, the second upper bending die 752 is provided with a multi-directional bending mechanism avoidance groove 7522 which opens upward and is used to avoid the positioning fixture 12. The side walls of the multi-directional bending mechanism avoidance groove 7522 are the second upper bending rib 7521. The second upper bending rib 7521 is provided with an avoidance channel 7523 for the side pressure die 754 to pass through. The two ends of the avoidance channel 7523 lead to the inner side and outer side of the second upper bending rib 7521 respectively. The inner side of the second upper bending rib 7521 is provided with an upper bending guide groove 7524. The top end of the upper bending guide groove 7524 extends to the top end of the second upper bending rib 7521 and forms a second upper bending guide arc surface 7525. The bottom end of the upper bending guide groove 7524 extends to the avoidance channel 7523.

[0111] refer to Fig.32The working principle of the pin multi-directional bending mechanism 7 is as follows:

[0112] 1. The workpiece conveying mechanism 1 conveys the inductor to the position between the multi-directional bending upper die assembly 74 and the multi-directional bending lower die assembly 75. At this time, the inductor is in the positioning fixture 12 (the positioning fixture is Fig.32 2. The multi-directional bending mechanism upper die cylinder 72 drives the multi-directional bending upper die assembly 74 to move downward, so that the multi-directional bending mechanism buffer ejector pin 745 presses the inductor 10 until the fork teeth 7441 of the limiting fork 744 abut against the upper end of the inductor 10; 3. The multi-directional bending mechanism lower die cylinder 73 drives the multi-directional bending lower die assembly 75 to move upward, and the second upper bending ridge 7521 of the second upper bending punch 752 bends the root of the pin 101 upward. The root of the pin 101 is specifically bent by the second upper bending guide arc surface 7525 and is limited by the upper bending guide groove 7524, which makes the upper folded portion of the pin tilt toward the direction of the pin limiting channel 7442 (reference Fig.35 S5 in the figure), thereby entering the pin limiting channel 7442 and being located below the lower bending plate 7431, and the upper bending guide groove 7524 can effectively prevent the pin 101 from deviating from the direction during the upper bending process; Fourth, the side pressure cylinder 753 is started, and the side pressure die 754 is laterally displaced, thereby pressing the pin 101 (root) against the side of the inductor 10 shell; Fifth, the lower bending cylinder 742 is started, and the lower bending plate 7431 of the lower bending die 743 moves downward along the pin limiting channel 7442, thereby accurately pressing the pin 101 to the preset position at the upper end of the inductor shell; Sixth, this process is completed, and the multi-directional bending upper die assembly 74 and the multi-directional bending lower die assembly 75 are reset.

[0113] refer to Fig.33 The pin pressing mechanism 8 of this embodiment includes a pressing mechanism frame 81, a pressing cylinder 82 and a pressing die assembly 83. The pressing mechanism frame 81 is provided with a pressing mechanism lifting rail 84. The pressing cylinder 82 is installed on the pressing mechanism frame 81. The pressing die assembly 83 is slidably assembled on the pressing mechanism lifting rail 84. The pressing cylinder 82 is used to drive the pressing die assembly 83 to move up and down. The pressing die assembly 83 includes a pressing die seat 831 and a pressing die 832. The upper side of the pressing die 832 is equipped with a buffer. The upper end of the buffer is limited by the pressing die seat 831, and the lower end of the buffer is limited by the pressing die 832. Although the pin multi-directional bending mechanism 7 has pressed the pin of the inductor once (i.e., the bending action), after the mechanism is reset, there is a certain probability that the inductor pin will be lifted. Therefore, the pin pressing mechanism 8 is used to press the inductor pin for a second time.

[0114] refer to Fig.35 The overall workflow of the automated pin forming intelligent manufacturing machine is as follows:

[0115] A. The loading mechanism 2 grabs the inductor to be processed onto the positioning fixture 12 of the workpiece conveying mechanism 1, and then the workpiece conveying mechanism 1 sequentially conveys the inductor to the stations where the pin forming mechanisms are located for processing;

[0116] B. The workpiece conveying mechanism 1 conveys the inductor to the position where the pin straightening mechanism 3 is located for horizontal straightening processing, so that the pins of the inductor are horizontally straightened (reference Fig.35 S1); when the pins of the inductor are made of thin and soft metal materials such as copper wire, the pins of the inductor are prone to bending and deformation during storage and transportation. Therefore, the pins of the inductor need to be horizontally straightened by the pin straightening mechanism 3 to ensure the processing accuracy of subsequent processes.

[0117] C. The workpiece conveying mechanism 1 conveys the inductor to the station where the pin pre-cutting mechanism 4 is located for pre-cutting processing, so that the length of the inductor pin is shortened (refer to Fig.35 S2).

[0118] D. The workpiece conveying mechanism 1 conveys the inductor to the station where the pin pre-bending mechanism 5 is located for pre-bending processing, so that the pin of the inductor is transformed from a horizontal straightened state to an L-shaped structure state (refer to Fig.35 in S3).

[0119] E. The workpiece conveying mechanism 1 conveys the inductor to the workstation where the pin fine cutting mechanism 6 is located for fine cutting, and the length of the upper folding portion 1012 of the pin is cut with high precision (refer to Fig.35 in S4).

[0120] F. The workpiece conveying mechanism 1 conveys the inductor to the station where the pin multi-directional bending mechanism 7 is located for multi-directional bending processing, and the upper bending and side pressure of the pin root make the inductor reach Fig.35 The state of S5 in the middle, and then bend down to make the inductor finally reach Fig.35 The status of S6.

[0121] G. The workpiece conveying mechanism 1 conveys the inductor to the station where the pin pressing mechanism 8 is located for secondary pressing processing, thereby solving the problem that the inductor pins may be lifted up and further improving the processing quality.

[0122] H. The workpiece conveying mechanism 1 conveys the inductor to the workstation where the unloading mechanism 9 is located, and the unloading mechanism 9 grabs the processed inductor to the unloading tray assembly.

[0123] In summary, the automated pin forming intelligent manufacturing integrated machine of the embodiment of the present invention can accurately control the cutting and bending of the inductor pins to prevent erroneous deformation and direction deviation, thereby improving the yield and production efficiency of the inductor device.
