The frame 1 is provided with a PIN nail disassembling mechanism 2 and a first driving device 3 for driving the PIN nail disassembling mechanism 2 to move in the X-axis direction. A second driving device 4 for driving the first driving device 3 to move in the Y-axis direction is arranged at the top of the frame 1. A material conveying mechanism 5 for conveying a carrier plate is arranged below the PIN nail disassembling mechanism 2, and a recovery container 6 for recovering the disassembled PIN nails is arranged below the material conveying mechanism 5.

[0047] After stacking and arranging multiple circuit boards in an orderly manner up and down, the multiple circuit boards are clamped and carried through tools such as a carrier plate and PIN nails for convenient transmission and transportation. The material conveying mechanism 5 automatically conveys the carrier plate to the lower part of the PIN nail disassembling mechanism 2, and then the second driving device 4 drives the first driving device 3 to move in the Y-axis direction, and the first driving device 3 drives the PIN nail disassembling mechanism 2 to move in the X-axis direction, so as to drive the PIN nail disassembling mechanism 2 to move in the Y-axis direction and the X-axis direction, align the position of the PIN nail by the PIN nail disassembling mechanism 2 and apply an accurate punching force to the PIN nail, so as to punch out the PIN nail from the carrier plate. The punched and disassembled PIN nails are recovered by the recovery container 6 for easy removal and cleaning of the PIN nails. By adopting the method of aligning first and then punching, the PIN nails can be concentratedly stressed, effectively avoiding the situations such as the breakage of the punching needle 27, personal injury, and damage to the circuit board, thereby improving the production efficiency and reducing the labor cost.

Specifically, two conveyor belts 53 are arranged relatively to each other, and the carrier is automatically transported by the two conveyor belts 53. During the process of transporting the carrier, the carrying platform 51 supports the carrier, and then the control system in the equipment controls the conveyor belt 53 to stop running, so that the carrier is parked on the conveyor belt 53, and the lifting device 55 lifts the carrier upward and makes the carrier separate from the contact with the conveyor belt 53, and then the position correction device 54 on the left and right sides pushes the carrier to slide on the lifting device 55, and adjusts and corrects the position of the carrier so that the carrier is aligned with the middle position of the carrying platform 51, and then the lifting device 55 drives the carrier to descend to the carrying platform 51, so that multiple positioning pins 52 are correspondingly inserted into the positioning through holes of the carrier, so that the carrier is stably and fixedly placed on the carrying platform 51, so as to facilitate the subsequent disassembly of the PIN nails, and the operation is stable and reliable.

[0049] like Figure 2 , Figure 4 and Figure 6 As shown, the bearing platform 51 of this embodiment is provided with a blocking and positioning structure 56 for blocking and positioning the carrier, the blocking and positioning structure 56 comprises a base frame 561, the base frame 561 is provided with a driving cylinder 562, the output end of the driving cylinder 562 is connected with a hook block 563, the top of the base frame 561 is provided with a hinge seat 564 connected with the hook block 563, and a hinge shaft 565 is connected between the hinge seat 564 and the hook block 563. Specifically, as a preference, two blocking and positioning structures 56 are provided, when a plurality of positioning pins 52 are correspondingly inserted into the positioning through holes of the carrier, the driving cylinder 562 drives one end of the hook block 563 to move upward, and the other end of the hook block 563 rotates around the hinge seat 564 through the hinge shaft 565, thereby making the hook block 563 abut against the working position of the fixed carrier to achieve mechanical blocking, so that the carrier can be placed on the bearing platform 51 more stably and reliably, and the error caused by the working operation is reduced.

[0050] like Figure 2 and Figure 4As shown in the figure, the material conveying mechanism 5 of this embodiment is provided with a servo motor 57.

A transmission belt 511 is connected between the driving wheel 59 and the driven wheel 510. The driven wheel 510 is connected to a transmission rod 512, and the transmission rod 512 is in transmission connection with the conveyor belt 53. Specifically, the servo motor 57 drives the driving wheel 59 to rotate through the reducer 58. The driving wheel 59 drives the driven wheel 510 to rotate through the transmission belt 511. The driven wheel 510 drives the transmission rod 512 to rotate. The transmission rod 512 is in transmission connection with the conveyor belt 53, thereby realizing the automatic transportation of the carrier tray by the conveyor belt 53.

The output end of the first lifting cylinder 552 is connected to a ball eye bearing 553. A limit seat 554 for limiting the ball eye bearing 553 is provided at the top of the base frame 551. Specifically, the first lifting cylinder 552 drives the ball eye bearing 553 to move upward. The ball eye bearing 553 abuts against the limit seat 554, realizing the limit of the moving stroke of the ball eye bearing 553, with accurate positioning. When the position correction devices 54 on the left and right sides push the carrier tray to slide on the ball eye bearing 553 to adjust and correct the position of the carrier tray, the operation is convenient, time-saving and labor-saving.

One ends of the first guide rod 545 and the second guide rod 546 are both connected with the correction plate 544. The other end of the first guide rod 545 is connected with the first bushing 547, and the other end of the second guide rod 546 is connected with the second bushing 548. Specifically, as a preference, there are two mounting frames 541 which are respectively installed on both sides of the frame 1. The output ends of the first translation cylinder 542 and the second translation cylinder 543 jointly drive the correction plate 544 to move horizontally. The correction plate 544 is connected with the first guide rod 545 and the second guide rod 546. The first guide rod 545 is slidably connected with the first bushing 547, and the second guide rod 546 is slidably connected with the second bushing 548. The guiding property is good, further improving the moving smoothness of the correction plate 544.

Second sliders 35 are arranged on both sides of the moving frame 31. The frame 1 is provided with a second guide rail 11 which is slidably connected with the second sliders 35. Specifically, the first linear module 32 drives the disassembling PIN nail mechanism 2 to move horizontally through the sliding seat 33.

The output end of the second lifting cylinder 23 is connected with a support plate 24. A third lifting cylinder 25 is arranged on the support plate 24. The output end of the third lifting cylinder 25 is connected with a clamping head 26. A punching needle 27 is installed on the clamping head 26. A pressure seat 28 is arranged at the bottom of the support plate 24. The pressure seat 28 is provided with a positioning hole 29 for the punching needle 27 to pass through.

The second lifting cylinder 23 drives the support plate 24 to move up and down. The third lifting cylinder 25 installed on the support plate 24 drives the clamping head 26 to move up and down. The clamping head 26 is connected with the positioning hole 29 through the punching needle 27. First, the second lifting cylinder 23 drives the support plate 24 to move to the position of the carrier plate, so that the pressure seat 28 abuts and presses on the surface of the carrier plate. The third lifting cylinder 25 drives the punching needle 27 to guide through the positioning hole 29 of the pressure seat 28 through the clamping head 26, quickly punches the position of the PIN nail on the carrier plate and makes the PIN nail fall off. The fallen PIN nails are collected and recycled into the recycling container 6. Then, after lifting the punching needle 27 again, the first driving device 3 and the second driving device 4 cooperate with each other to automatically position the punching needle 27 in the X-axis and Y-axis directions, so as to facilitate a new round of PIN nail disassembling operation.
