In this embodiment, six rotating rods 4 are provided to rotate all six pins 13 at one time, thereby completing the processing at one time.

[0036] Furthermore, the rotating rods 4 are also connected to the rotating drive assembly 5; the rotating drive assembly 5 drives six rotating rods 4 to rotate at one time, thereby achieving synchronous rotation and one-time processing.

[0037] When the rotating fixing device is in use, the jig 2 automatically transports the coil 11 and the cover 12 to one side of the frame 1, under the several rotating rods 4, and the vertical drive component 3 drives the rotating rod 4 to move downward and insert into the cover 12. At this time, the end of each rotating rod 4 contacts the pin 13 and is engaged with each other; the rotating drive component 5 drives the rotating rod 4 to rotate, twisting the pin 13 90 degrees, so that the position of the pin 13 in the width direction and the thickness direction is interchanged, and the pin 13 and the groove 14 are perpendicular to each other to complete the fixed connection.

[0038] In this embodiment, if Figure 3 As shown, in order to stably place the coil 11 on the jig 2, the jig 2 is provided with two placement grooves 21, and the placement grooves 21 are adapted to the lower part of the coil 11; further, in this embodiment, two placement grooves 21 are provided, which can transport two coils 11 and the cover plate 12 at one time, and can also complete the fixation of the two coils 11 and the cover plate 12 at one time.

[0043] Furthermore, in order to ensure the stability of the connection between the first placement plate 31 and the second placement plate 312, a reinforcing support plate 36 is installed at the lower part of the second placement plate 312. One side of the reinforcing support plate 36 is fixedly connected to the first placement plate 311, and the other side is fixedly connected to the second placement plate 312.

[0044] like Figure 4As shown, the rotation drive assembly 5 is installed on the placement plate 31 and is in transmission connection with the rotation rod 4 to drive the rotation rod 4 to rotate.

[0045] Specifically, in this embodiment, a power source is used to drive twelve rotating rods 4 to rotate; the lateral motion is converted into rotational motion; the rotation drive assembly 5 includes a lateral cylinder 51 installed on the first placement plate 311 and a lateral drive block 52 installed at the end of the lateral cylinder 51; the lateral cylinder 51 drives the lateral drive block 52 to reciprocate laterally; two insertion grooves 56 are installed at the lower part of the lateral drive block 52, which subsequently drive the two turntables 53 to rotate; the lateral motion of the lateral cylinder 51 is converted into the rotational motion of the two turntables 53.

[0046] like Figure 7 As shown, the rotation drive assembly 5 also includes a turntable 53 installed on the second placement plate 312, and the turntable 53 can be rotated at a certain angle on the second placement plate 312 to complete the twisting of the pin 13 by 90 degrees; further, a driving protrusion 55 is provided at one end of the turntable 53, and the driving protrusion 55 is inserted into the insertion groove 56 and is connected to the horizontal cylinder 51 for transmission; a plurality of arc-shaped grooves 54 are provided inside the turntable 53, and there are six arc-shaped grooves 54, which respectively accommodate six rotating rods 4.

[0047] Furthermore, a rotating block 41 is installed at the end of the rotating rod 4, and the rotating block 41 drives the rotating rod 4 to rotate; the rotating block 41 is installed inside the arc-shaped groove 54, and the outer side of the rotating block 41 is adapted to the inner side of the arc-shaped groove 54; the arc-shaped groove 54 pushes the rotating block 41 to move, thereby indirectly pushing the rotating rod 4 to rotate.

[0048] The movement process of the rotary drive assembly 5 is as follows: the transverse cylinder 51 moves transversely, driving the transverse drive block 52 to move transversely; the transverse drive block 52 drives the turntable 53 to rotate, and the arc-shaped groove 54 of the turntable 53 drives the rotating block 41, and the rotating block 41 moves along the arc-shaped groove 54, thereby driving the rotating rod 4 to rotate and twisting the pin 13 90 degrees.

[0049] In order to precisely control the lateral movement, such as Figure 6 As shown, the rotary drive assembly 5 also includes a transverse guide rail 57 installed on the first placement plate 311 and a plurality of transverse sliders 58 mounted on the transverse guide rail 57. The transverse sliders 58 are fixedly connected to the transverse drive block 52, and the transverse drive block 52 moves laterally along the transverse guide rail 57.

[0050] like Figure 9As shown, a mounting plate 61 is installed at the lower part of the turntable 53, and the mounting plate 61 is installed on the second placement plate 312. The rotating block 41 is installed on the mounting plate 61, and the lower end of the rotating rod 4 passes through the mounting plate 61. In order to hard limit the turntable 53, as shown in FIG. Figure 7 As shown, a first limiting block 62 is installed on one side of the mounting plate 61 , and a second limiting block 63 is installed on the other side. The driving protrusion 55 is arranged between the first limiting block 62 and the second limiting block 63 .

[0051] In order to reduce friction during movement, a first bearing 551 is installed on the upper portion of the driving protrusion 55, and the first bearing 551 is inserted into the insertion groove 56; in this way, friction can be reduced during the process of converting lateral movement into rotational movement.

[0052] Furthermore, a fixed plate 64 is installed on the upper part of the turntable 53, and the fixed plate 64 limits the vertical upward movement of the rotating rod 4 and the rotating block 41 to maintain the stability of the rotational movement; the fixed plate 64 is connected to the mounting plate 61 through connecting rods 65 on all sides; a plurality of second bearings 66 are installed on the connecting rods 65, and the second bearings 66 are in contact with the outer side of the turntable 53.
