The left and right sides of the front end of the L-shaped frame 16 are fixedly connected to the legs 20, the front ends of the two legs 20 are fixedly connected to the slide rails 21, and the front sides of the two slide rails 21 are fixedly connected to the same U-shaped plate 22.

[0041] Specifically, when using the common bending equipment for connector multi-row pins, the first step is to place the multi-row pins securely on the bottom plate 15, then start the motor 2 11, drive the movable plate 12 to move backward along the preset trajectory, and then prompt the push plate 13 to push the clamping plate 14 and the bottom plate 15 to clamp the multi-row pins, and at the same time activate the motor 16 to prompt the rotating rod 17 to rotate, drive the moving block 18 and the horizontal plate 15 to move backward as a whole, so that the horizontal plate 2 10 guides the multi-row pins to gradually approach the bending plate 27 until the pins are fully inserted into it, and start the rotating motor. The machine 23 drives the rotating plate 24 to start rotating, and this rotation will drive the rotating shaft 28 to rotate synchronously, thereby prompting the connecting plate 25 and the second clamping plate 26 and the bending plate 27 to rotate as a whole, thereby realizing the precise bending operation of multiple rows of pins. The start of the motor 3 17 will trigger the rotation of the second rotating rod 18, further driving the moving block 2 19 and the U-shaped plate 22 to rise, and move the bending plate 27 out of the pins. By adjusting the position of the bending plate 27, it is aligned with the next row of pins to be processed, and the above-mentioned entire process is repeated to realize continuous and efficient bending processing of multiple rows of pins.

[0042] Reference Figure 2 and Figure 5 The sensing mechanism 2 includes a slide rail 3 201. The two slide rails 3 201 are respectively fixedly connected to the top left side of the base 1 and the front left end of the L-shaped frame 16. A groove 202 is formed on one side of each of the two slide rails 3 201. The interiors of the two grooves 202 are equidistantly slidably connected to movable U-shaped frames 203. One end of the plurality of movable U-shaped frames 203 is fixedly connected to a sensor 204. The left side of the slide rail 1 4 and the left side of the U-shaped plate 22 are both fixedly connected to a trigger 205.

[0043] Specifically, during the forward movement of the horizontal plate 5, the trigger 205 moves forward synchronously therewith. When the trigger 205 passes the preset sensor 204 position, the sensor 204 immediately transmits the detected signal to the rotating motor 23 to start the bending operation of the pins. After the bending operation of a row of pins is completed, the motor 3 17 is immediately started to drive the U-shaped plate 22 to drive the trigger 205 on the left to move downward to the predetermined position. At this time, the sensor 204 sends a signal again to trigger the motor 6 to start, and the pins are accurately inserted into the bending plate 27 to complete the subsequent bending process.

[0044] Reference Figure 1 and Figure 5 The four rear corners of the U-shaped plate 22 are fixedly connected to an L-shaped plate 29, and multiple L-shaped plates 29 are fixedly connected to the left and right sides of the U-shaped plate 22. Triangles 30 are fixed to the left and right sides of the top of the L-shaped frame 16. The front sides of the two triangles 30 are fixedly connected to the rear side of the L-shaped frame 16. Multiple movable U-shaped frames 203 are equidistantly slidably connected to the inside of the two grooves 202. The size of the multiple grooves 202 is consistent with that of the movable U-shaped frames 203.

[0045] Specifically, the L-shaped plate 29 plays a supporting and fixing role, so that the U-shaped plate 22 can better disperse the force when it is subjected to pressure and impact. The tripod 30 can reinforce the L-shaped frame 16 to make the L-shaped frame 16 more stable. The groove 202 is consistent with the size of the movable U-shaped frame 203, which can make the movable U-shaped frame 203 more stable when moving.

[0046] Reference Figure 2 and Figure 6 The top of the horizontal plate 5 is fixedly connected to a moving block 8, the bottom of the moving block 8 is slidably connected to the top of the base 1, the front end of the splint 26 is fixedly connected to a bending plate 27, and the front side of the bending plate 27 is fixedly connected to multiple bending tubes at equal intervals.

[0047] Specifically, the sliding connection between the moving block 1 8 and the top of the base 1 can make the moving block 1 more stable when moving, so that the bending plate 27 can bend the pin more accurately.

[0048] Working principle: When using the common bending device of the connector multi-row pins, the multi-row pins need to be placed on the top of the bottom plate 15 first. At this time, the motor 2 11 works to make the movable plate 12 move backward, so that the push plate 13 pushes the clamping plate 14 and the bottom plate 15 to clamp the multi-row pins. At the same time, the motor 1 6 works to make the rotating rod 1 7 rotate to drive the moving block 1 8 to move backward, drive the horizontal plate 1 5 to move backward so that the horizontal plate 2 10 drives the multi-row pins to move toward the bending plate 27 so that the pins are inserted into the bending plate 27. At the same time, the rotating motor 23 works to make the rotating plate 24 rotate. At this time, the rotating shaft 28 rotates accordingly, so that the connecting plate 25 rotates, drives the clamping plate 2 26 and the bending plate 27 to rotate, and bends the multi-row pins. At the same time, the motor 3 1 7 drives the rotating rod 2 18 to rotate, so that the moving block 2 19 drives the U-shaped plate 22 to move. At this time, the bending plate 27 moves upward to move the pins out. At this time, the bending plate 27 is turned back and the bending plate 27 is moved to the next row of pins. At this time, the above movement is repeated to bend multiple rows of pins, and when the horizontal plate 1 5 moves forward, it drives the trigger 205 to move forward. When the trigger 205 passes the preset sensor 204 position, the sensor 204 transmits information to the rotating motor 23 to bend the pins. When the bending of a row of pins is completed, the motor 3 17 works to let the U-shaped plate 22 drive the trigger 205 on the left to move downward. When the predetermined position is reached, the sensor 204 lets the motor 1 6 work to insert the pins into the bending plate 27 for bending.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
