[0030] Example: Figure 1-10 As shown, a coil bending mechanism includes a frame 100 and a pressure-holding unit 200 and a bending unit 300 mounted on the frame 100. A base plate 140 is fixedly mounted on the frame 100, and a product seat 141 is fixedly mounted on the base plate 140. The product seat 141 supports a coil 400. The coil 400 has an inner lead and an outer lead 410. The pressure-holding unit 200 includes a rotary clamping cylinder 210 and a pressure-holding block 230 connected to the rotary clamping cylinder 210. The bending unit 300 includes a drive cylinder 310, an inner lead clamping unit 320, and an outer lead clamping unit 330. The inner lead clamping unit 320 includes an inner lead movable clamping block 321 and an inner lead fixed clamping block 323. The outer lead clamping unit 330 includes an outer lead movable clamping block 331 and an outer lead fixed clamping block 333. The rotary pressing cylinder 210 can drive the pressure holding block 200 to press the coil 400 on the product seat 141. Under the action of the driving cylinder 310, the inner lead movable clamping block 321 can approach the inner lead fixed clamping block 323 to bend the inner lead, and the outer lead movable clamping block 331 can approach the outer lead fixed clamping block 333 to bend the outer lead 410.

[0031] During operation, the drive cylinder 310 drives both the inner lead clamping unit 320 and the outer lead clamping unit 330 to the open state. The coil 400 is placed on the product seat 141. The inner lead is placed between the inner lead movable clamping block 321 and the inner lead fixed clamping block 323, and the outer lead 410 is placed between the outer lead movable clamping block 331 and the outer lead fixed clamping block 333. Then, the rotating clamping cylinder 210 drives the pressure holding block 230 to move, so that the pressure holding block 230 presses the coil 400. Under the drive of the drive cylinder 310, the inner lead movable clamping block 321 moves toward the inner lead fixed clamping block 323 until the inner lead is clamped and straightened, and the outer lead movable clamping block 331 moves toward the outer lead fixed clamping block 333 until the outer lead 410 is clamped and straightened, thereby completing the bending operation of the inner and outer leads of the coil. The coil bending mechanism in this application includes a pressure holding unit 200 and a bending unit 300. The pressure holding unit 200 is used to fix the coil 400, and the bending unit is used to clamp and straighten the inner and outer leads on the coil 400, i.e., bend them so that the inner and outer leads are on the same straight line. This coil bending mechanism can ensure the consistency of the angle and size of each bend, improve the quality of the product, and through automatic control, it can process products quickly and continuously, which is suitable for large-scale production, reduces the dependence on manual labor, and lowers labor costs.

[0032] like Figure 5 and Figure 10 As shown, the frame 100 is provided with a first support plate 110, a second support plate 120, and a third support plate 130. The drive cylinder 310 is mounted on the first support plate 110, the rotary clamping cylinder 210 is mounted on the second support plate 120, the base plate 140 is mounted on the third support plate 130, and the inner lead wire clamping unit 320 and the outer lead wire clamping unit 330 are mounted between the third support plate 130 and the base plate 140. Optionally, the first support plate 110 and the third support plate 130 are located inside the frame 100, the second support plate 120 is located outside the frame 100, and the third support plate 130 is located above the first support plate 110. In this embodiment, a second support plate 120 is provided on each side of the frame 100. A pressure holding unit 200 is fixedly installed on each second support plate 120. A drive cylinder 310 simultaneously controls two sets of inner lead movable clamping blocks 321 and outer lead movable clamping blocks 331, so that two sets of coils 400 can be bent at the same time, improving work efficiency.

[0033] like Figure 10As shown, the piston rod of the drive cylinder 310 is fixedly connected to the pull rod 311. When the piston rod of the drive cylinder 310 moves, the pull rod 311 can drive the inner lead wire movable clamping block 321 and the outer lead wire movable clamping block 331 to move. That is, the pull rod 311 can drive the inner lead wire movable clamping block 321 away from or near the inner lead wire fixed clamping block 323, and the outer lead wire movable clamping block 331 away from or near the outer lead wire fixed clamping block 333. By using the pull rod 311 to act on the inner lead wire movable clamping block 321 and the outer lead wire movable clamping block 331, the inner lead wire clamping unit 320 and the outer lead wire clamping unit 330 can achieve the function of opening or closing.

[0034] like Figure 10 As shown, a baffle 131 is fixedly installed on the third support plate 130. A first spring 322 is provided between the inner lead wire movable clamp 321 and the baffle 131, and a second spring 332 is provided between the outer lead wire movable clamp 331 and the baffle 131. A first bearing 134 and a second bearing 136 are movably installed inside the third support plate 130. The first bearing 134 is fixedly connected to the inner lead wire movable clamp 321, and the second bearing 136 is fixedly connected to the outer lead wire movable clamp 331. The pull rod 311 can drive the movement of the first bearing 134 and the second bearing 136, thereby driving the inner lead wire movable clamp 321 and the outer lead wire movable clamp 331 to move respectively.

[0035] like Figure 10 As shown, the first bearing 134 is fixedly connected to the inner lead wire movable clamp 321 via the first connecting rod 135, and the second bearing 136 is fixedly connected to the outer lead wire movable clamp 331 via the second connecting rod 137. The pull rod 311 is movably placed on the third support plate 130, and the pull rod 311 is provided with an inclined surface 312, which acts on the first bearing 134 and the second bearing 136. The baffle 131, the inner lead wire fixing clamp 323, and the outer lead wire fixing clamp 333 are fixedly installed on the third support plate 130. Figure 10As shown, when the piston rod of the drive cylinder 310 retracts, the inclined surface 312 on the pull rod 311 applies a horizontal leftward force to the first bearing 134 and the second bearing 136. The bearings drive the inner lead wire movable clamp 321 and the outer lead wire movable clamp 331 to move synchronously, thereby moving them away from the inner lead wire fixed clamp 323 and the outer lead wire fixed clamp 333 respectively, causing the inner lead wire clamping unit 320 and the outer lead wire clamping unit 330 to open. At this time, the first spring 322 and the second spring 332 are compressed; when the inner lead wire is released... After the inner lead wire is placed between the inner lead wire fixing clamp 323 and the inner lead wire movable clamp 321, and the outer lead wire 410 is placed between the outer lead wire movable clamp 331 and the outer lead wire fixing clamp 333, the pressure holding unit 200 presses the coil 400, the piston rod of the drive cylinder 310 extends, the inclined surface 312 of the pull rod 311 leaves the first bearing 134 and the second bearing 136, and the inner lead wire movable clamp 321 and the outer lead wire movable clamp 331 are reset, thereby clamping and straightening the inner lead wire and the outer lead wire 410 to complete the bending operation.

[0036] like Figure 10 As shown, the third support plate 130 has a first notch 132 and a second notch 133. The first notch 132 and the pull rod 311 are located on opposite sides of the first bearing 134, and the second notch 133 and the pull rod 311 are located on opposite sides of the second bearing 136. Under the action of the inclined surface 312, the first bearing 134 moves into the first notch 132, and the second bearing 136 moves into the second notch 133. The first notch 132 and the second notch 133 serve as the movement spaces for the first bearing 134 and the second bearing 136, respectively.

[0037] like Figure 9-10 As shown, a first receiving groove 142 is formed on the base plate 140, and a second receiving groove 143 is formed in the product seat 141. The inner lead wire fixing clip 323 and the outer lead wire fixing clip 333 are fixedly installed on the third support plate 130, and the inner lead wire movable clip 321 and the inner lead wire fixing clip 323 extend into the second receiving groove 143, while the outer lead wire movable clip 331 and the outer lead wire fixing clip 333 extend into the first receiving groove 142. This facilitates the bending of the inner and outer leads 410.

[0038] like Figure 3 and Figure 10 As shown, the first support plate 110 is provided with a slide rail 111, and a slider 112 is slidably mounted on the slide rail 111. The piston rod of the drive cylinder 310 is connected to the slider 112, and the slider 112 is fixedly connected to the pull rod 311 through a connecting block 113. The piston rod of the drive cylinder 310 drives the slider 112 to slide on the slide rail, and the slider 112 drives the pull rod 311 to move through the connecting block 113.

[0039] like Figure 1 and Figure 7 As shown, the rotary clamping cylinder 210 is vertically mounted on the second support plate 120. The pressure holding block 230 is fixedly connected to the piston rod of the rotary clamping cylinder 210. The pressure holding block 230 is provided with a pressure rod 232 and a limiting bolt 233. The rotary clamping cylinder 210 can rotate and rise simultaneously. It is a device driven by pneumatic or hydraulic pressure, which clamps and presses the workpiece through rotational motion. The rotary clamping cylinder 210 is widely used in clamping applications requiring rotational motion and has advantages such as compact structure, smooth movement, and large clamping force. The limiting bolt 233 can control the descent height of the pressure holding block 230. By adjusting the position of the limiting bolt 233, it can adapt to the pressure holding requirements of different products. The pressure rod 232 is used to assist the pressure holding block 230 in pressing the product.

[0040] like Figure 5-7 As shown, a guide block 220 is fixedly provided on the second support plate 120, and a third bearing 231 is provided on the pressure holding block 230. When the rotary pressing cylinder 210 drives the pressure holding block 230 to rise, the third bearing 231 slides along the guide block 220. The guide block 220 is used to limit the rotation angle of the rotary pressing cylinder 210. By utilizing the configuration of the third bearing 231 and the guide block 220, the upward direction of the pressure holding block 230 can be guided.

[0041] The operation process of this application includes the following steps:

[0042] Step 1: Place the coil 400 on the product holder 141, with the inner lead located in the inner lead clamping unit 320 and the outer lead 410 located in the outer lead clamping unit 330;

[0043] Step 2: Rotate the clamping cylinder 210 to drive the pressure holding block 230 to move downward until the pressure holding block 230 clamps the coil 400, thus fixing the coil 400.

[0044] Step 3: The piston rod of the drive cylinder 310 extends, driving the inner lead wire movable clamping block 321 and the outer lead wire movable clamping block 331 to move toward the inner lead wire fixed clamping block 323 and the outer lead wire fixed clamping block 333 respectively, so that the inner lead wire and the outer lead wire 410 are clamped and straightened, thus completing the bending operation.

[0045] Step 4: The piston rod of the drive cylinder 310 retracts, the inner lead clamping unit 320 and the outer lead clamping unit 330 open, and the inner lead and the outer lead are released;

[0046] Step 5: Rotate the clamping cylinder 210 to drive the pressure holding block 230 to move in the opposite direction, and the pressure holding block 230 releases the coil 400.

[0047] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
