[0001] This invention relates to the field of cutting and processing technology, specifically to a cutting and processing apparatus and operating method for the production of electrical connectors. Background Technology

[0002] Electrical connectors, also known as electronic connectors or connectors, are electromechanical components used to connect electronic circuits and transmit signals or electricity. The conductive pins of electrical connectors need to be cut to fit different interfaces during use.

[0003] In the prior art, patent number CN120237500A, entitled "An Electrical Connector Production Device," relates to the technical field of electrical connector production devices. It mainly includes a mounting plate and a conveying mechanism, a stamping mechanism, a transfer mechanism, and a spring mechanism mounted on it. The conveying mechanism uses first and second perpendicular conveying tables in conjunction with transfer blocks to achieve workpiece transfer; the stamping mechanism uses stamping blocks and pressing blocks to complete the stamping and fixing of connectors; the transfer mechanism uses multiple components to complete the precise splicing and unloading operations of connectors; and the spring mechanism uses springs and sliding structures to achieve efficient unloading, thus achieving the technical effects of improving connector production efficiency, ensuring splicing accuracy, and optimizing unloading reliability.

[0004] However, existing conductive pins require manual placement and fixation of the parts before cutting. This manual placement can cause the parts to shift, resulting in the cut workpiece not meeting the requirements. Summary of the Invention

[0010] Preferably, a cutting table is fixed to the bottom of the baffle, and a cutting groove is formed on the surface of the cutting table. The cutting blade is located at the top of the cutting table and is held in the cutting groove after it descends. A lifting device is provided at the top of the lifting rod, and the lifting device drives the lifting rod to move up and down. The connecting plate and the cutting blade move up and down with the lifting rod. A second spring is provided in the opening. The second spring connects the end of the telescopic rod and the inside of the L-shaped rod. The telescopic rod can be inserted into the L-shaped rod. A first limiting strip is fixed to the bottom of the lower pressure plate.

[0011] Preferably, a gravity ball is fixed to the bottom of the fixed platform, and a fixed ring is fixed to the surface of the fixed platform. The surface of the fixed ring is provided with teeth. The fixed platform and the fixed ring move together. A transverse rod is inserted into the end of the fixed ring. The transverse rod can rotate inside the fixed ring. A limit ring is provided at one end of the transverse rod inside the fixed ring. The limit ring is always located in the fixed ring and rotates with the transverse rod. A transverse moving device is provided at the other end of the transverse rod. The transverse moving device drives the transverse rod to move.

[0012] Preferably, an arc-shaped plate is provided on the outside of the transverse rod, and an air inlet pipe is fixed on the surface of the arc-shaped plate. The end of the air inlet pipe is connected to an air blowing device, so that air enters the interior of the arc-shaped plate through the air inlet pipe. A material drop groove is provided at the bottom of the arc-shaped plate, and the fixed platform can enter the interior of the arc-shaped plate after moving with the transverse rod.

[0013] Preferably, there are two sets of the second slot, located on both sides of the first slot. An adjustment plate is inserted into the second slot, and a connecting rod is fixed to the surface of the adjustment plate. The other end of the connecting rod is inserted into the inside of the fixed platform. A spring is provided on the outside of the connecting rod. One end of the spring is connected to the surface of the adjustment plate, and the other end is connected to the inner wall of the second slot. The adjustment plate can move in the second slot. A second limiting strip is fixed to the top of the adjustment plate. There are multiple sets of second limiting strips. After the pressure plate descends, it can hold the adjustment plate against the surface of the adjustment plate. The first limiting strip at the bottom of the pressure plate can be locked between the second limiting strips, so that the adjustment plate is stable in the second slot.

[0014] Preferably, the surface of the fixed platform is provided with a groove, the lower pressure plate is inserted into the groove after insertion, the surface of the adjusting plate is provided with a telescopic groove, a pushing device is provided in the telescopic groove, a clamping plate is inserted into the telescopic groove, the clamping plate can move in the telescopic groove, the pushing device pushes the clamping plate to move, the two sets of clamping plates can move closer to each other and further away from each other, the surface of the clamping plate is fixed with a rubber pad, the workpiece can be placed between the two sets of rubber pads, and the two sets of rubber pads can clamp the surface of the workpiece.

[0015] Preferably, an extension ring is fixed to the surface of the arc-shaped plate, and a through hole is opened on the surface of the extension ring. The transverse rod is inserted into the through hole and can move in the through hole.

[0016] Preferably, the surface of the extension ring is provided with a through groove, and a motor is fixed on the surface of the extension ring. One end of the motor is provided with a gear, which can drive the gear to rotate. One end of the gear is inserted into the through groove. After the fixed platform and the fixed ring move into the arc plate, the teeth on the surface of the fixed ring can mesh with the teeth on the surface of the gear, and the fixed ring is driven to rotate by the rotation of the gear.

[0017] Preferably, after the lifting rod descends, the cutting blade cuts on the surface of the workpiece, the telescopic rod can be retracted into the L-shaped rod, and the lower pressure plate always presses against the surface of the adjusting plate.

[0018] A method for operating a cutting and processing apparatus for manufacturing electrical connectors includes the following steps:

[0019] Step 1: Fixing. One end of the transverse rod is connected to the drive device. The drive device drives the transverse rod to move laterally, placing the workpiece in the first slot. Two sets of rubber pads clamp the surface of the workpiece, pre-fixing the workpiece in the first slot. The fixing rod descends, causing the lower pressure plate to descend, pressing the lower pressure plate into the groove. The downward pressure of the lower pressure plate makes the workpiece flat in the first slot. The lower pressure plate rises and is held against the end of the clamping plate by the pushing device in the telescopic groove, so that the two sets of clamping plates clamp the surface of the workpiece, stabilizing the workpiece in the first slot. The transverse rod moves, causing the fixing table to move, so that one end of the workpiece is held against the surface of the baffle. Since the adjusting plate can move in the second slot, one end of the workpiece is aligned.

[0020] Step 2: Cleaning. The horizontal moving rod moves the fixed platform into the interior of the arc-shaped plate, causing the fixed ring and gear to mesh. The motor drives the gear to rotate, which in turn drives the fixed ring to rotate. The fixed ring is fixed to the end of the fixed platform, and the horizontal moving rod is inserted into the fixed ring and the fixed platform. The fixed platform can rotate with the fixed ring. The centrifugal force of the rotation causes the debris to detach from the first slot, and the air inlet pipe blows air into the interior of the arc-shaped plate, causing the debris to fall from the discharge chute.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The present invention proposes a transverse rod connected to a driving device at one end. The driving device drives the transverse rod to move laterally, placing the workpiece in the first slot. Two sets of rubber pads clamp the surface of the workpiece, pre-fixing the workpiece in the first slot. The fixing rod descends, causing the lower pressure plate to descend, pressing the lower pressure plate into the groove. The downward pressure of the lower pressure plate makes the workpiece flat in the first slot. The lower pressure plate rises and is held against the end of the clamping plate by the pushing device in the telescopic groove, so that the two sets of clamping plates clamp the surface of the workpiece, stabilizing the workpiece in the first slot. The movement of the transverse rod drives the fixed platform to move, so that one end of the workpiece is held against the surface of the baffle. Since the adjusting plate can move in the second slot, one end of the workpiece is aligned. Attached Figure Description

The lifting rod 13 descends, causing the lower pressure plate 10 to descend, so that the lower pressure plate 10 is pressed down in the groove 34. The lower pressure plate 10 presses down, so that the workpiece is flat in the first slot 18. The lower pressure plate 10 rises and is held at the end of the clamping plate 21 by the pushing device in the telescopic groove 22, so that the two sets of clamping plates 21 are clamped on the surface of the workpiece, stabilizing the workpiece in the first slot 18.

A workpiece can be placed between the two sets of rubber pads 20. The two sets of rubber pads 20 can clamp the surface of the workpiece.

[0039] An arc-shaped plate 3 is provided on the outside of the transverse rod 4. An air inlet pipe 17 is fixed on the surface of the arc-shaped plate 3.

The teeth on the surface of the fixed ring 16 can mesh with the teeth on the surface of the gear 30. The rotation of the gear 30 drives the fixed ring 16 to rotate. After the cutting blade 7 descends with the lifting rod 13, the cutting blade 7 cuts on the surface of the workpiece. The telescopic rod 11 can be retracted into the L-shaped rod 12. The lower pressure plate 10 is always held against the surface of the adjusting plate 25. The first limiting strip 14 at the bottom of the lower pressure plate 10 is locked between the second limiting strip 26 on the surface of the adjusting plate 25, stabilizing the position of the adjusting plate 25 and stabilizing the position of the workpiece. After the lifting rod 13 continues to descend, the cutting blade 7 cuts the workpiece, and the telescopic rod 11 can be retracted into the L-shaped rod 12.

The transverse rod 4 drives the fixed table 5 to move into the interior of the arc plate 3.

[0040] One end of the transverse rod 4 is connected to the drive device, which drives the transverse rod 4 to move laterally, placing the workpiece in the first slot 18. Two sets of rubber pads 20 clamp the surface of the workpiece, pre-fixing the workpiece in the first slot 18. The lifting rod 13 descends, causing the lower pressure plate 10 to descend, pressing the lower pressure plate 10 into the groove 34. The downward pressure of the lower pressure plate 10 makes the workpiece flat in the first slot 18. The lower pressure plate 10 rises and is held against the end of the clamping plate 21 by the pushing device in the telescopic groove 22, so that the two sets of clamping plates 21 clamp the surface of the workpiece, stabilizing the workpiece in the first slot 18. The movement of the transverse rod 4 causes the fixed platform 5 to move, so that one end of the workpiece is held against the surface of the baffle 2. Since the adjusting plate 25 can move in the second slot 19, one end of the workpiece is aligned. The lifting rod 13 continues to descend, causing the lower pressure plate 10 to continue to descend. The first limit strip 14 at the bottom of the lower pressure plate 10 is locked into the adjusting plate 25. Between the second limiting strips 26 on the surface, the position of the adjusting plate 25 is stabilized, so that the position of the workpiece is stable. After the lifting rod 13 continues to descend, the workpiece is cut by the cutting blade 7, and the telescopic rod 11 can be retracted into the L-shaped rod 12. The spring in the L-shaped rod 12 holds the end of the telescopic rod 11, so that the lower pressure plate 10 always holds the surface of the adjusting plate 25. The transverse rod 4 drives the fixed platform 5 to move into the interior of the arc plate 3, so that the fixed ring 16 and the gear 30 mesh. The motor 29 drives the gear 30 to rotate, and the gear 30 can drive the fixed ring 16 to rotate. The fixed ring 16 is fixed to the end of the fixed platform 5, and the transverse rod 4 is inserted into the interior of the fixed ring 16 and the fixed platform 5. The fixed platform 5 can rotate with the fixed ring 16. The centrifugal force of the rotation causes the debris to be separated from the first slot 18, and the air inlet pipe 17 blows air into the interior of the arc plate 3, causing the debris to fall from the discharge chute 33.

[0041] A method for operating a cutting and processing apparatus for manufacturing electrical connectors includes the following steps:

[0042] Step 1: Fixing. One end of the transverse rod 4 is connected to the drive device. The drive device drives the transverse rod 4 to move laterally, placing the workpiece in the first slot 18. Two sets of rubber pads 20 clamp the surface of the workpiece, pre-fixing the workpiece in the first slot 18. The fixing rod 1 descends, causing the lower pressure plate 10 to descend, pressing the lower pressure plate 10 into the groove 34. The downward pressure of the lower pressure plate 10 makes the workpiece flat in the first slot 18. The lower pressure plate 10 rises and is held against the end of the clamping plate 21 by the pushing device in the telescopic groove 22, so that the two sets of clamping plates 21 clamp the surface of the workpiece, stabilizing the workpiece in the first slot 18. The transverse rod 4 moves, causing the fixing table 5 to move, so that one end of the workpiece is held against the surface of the baffle 2. Since the adjusting plate 25 can move in the second slot 19, one end of the workpiece is aligned.

[0043] Step 2: Cleaning. The horizontal moving rod 4 moves the fixed platform 5 to the inside of the arc plate 3, so that the fixed ring 16 and the gear 30 mesh. The motor 29 drives the gear 30 to rotate, and the gear 30 can drive the fixed ring 16 to rotate. The fixed ring 16 is fixed to the end of the fixed platform 5, and the horizontal moving rod 4 is inserted into the fixed ring 16 and the fixed platform 5. The fixed platform 5 can rotate with the fixed ring 16. The centrifugal force of the rotation causes the debris to detach from the first slot 18, and the air inlet pipe 17 blows air into the inside of the arc plate 3, causing the debris to fall from the discharge chute 33.
