[0056] Specifically, the rotation of the flipping motor 223 drives the flipping motor transmission component 224 to rotate, which in turn drives the rotating shaft 225 of the flipping assembly to rotate, thereby driving the flipping clamp cylinder 222 to rotate. The flipping motor 223 first rotates the flipping clamp cylinder 222 to the direction rotation component 21. After the flipping clamp cylinder 222 clamps the coaxial line on the direction rotation component 21, the flipping motor 223 flips the flipping clamp cylinder 222.

[0057] The flipping clamp cylinder 222 can be set on one side of the clamping cylinder 213 along the first direction D1, or it can be set above or below the clamping cylinder 213. The flipping angle driven by the flipping motor 223 to flip the flipping clamp cylinder 222 can be designed according to actual needs, such as 90°, 180°, etc.

[0058] Please see Figure 3 In some embodiments, the transport component 23 includes a transport servo motor 231, a slide rail component 232, a transport synchronous pulley 233, a transport synchronous belt 234, and a transport component fixing frame 235. One end of the transport component fixing frame 235 is connected to the frame 1, and the other end is connected to the slide rail component 232. The slide rail component 232 protrudes from the frame 1 along the first direction D1. Transport synchronous pulleys 233 are respectively provided at both ends of the slide rail component 232. The transport synchronous belt 234 connects the transport synchronous pulleys 233 at both ends of the slide rail component 232. The transport synchronous pulley 233 near the frame 1 is connected to the transport servo motor 231. The angle flipping component 22 is connected to the slide rail component 232 and the transport synchronous belt 234, and is located between the transport synchronous pulleys 233 at both ends of the slide rail component 232. The transport servo motor 231 is used to drive the angle flipping component 22 to move along the first direction D1.

[0059] Specifically, the transport servo motor 231 drives the transport synchronous wheel 233 to rotate, which in turn drives the transport synchronous belt 234 to move, thereby driving the angle flipping component 22 to move along the length direction of the slide rail component 232. That is, the transport servo motor 231 drives the angle flipping component 22 to move closer to or further away from the direction of the first direction D1 and the rotation component 21 to move.

[0060] Alternatively, the conveying component 23 can first drive the angle flipping component 22 to move away from the direction rotation component 21, and then the flipping motor 223 can flip the flipping clamp cylinder 222. Or, the flipping motor 223 can first flip the flipping clamp cylinder 222, and then the conveying component 23 can drive the angle flipping component 22 to move away from the direction rotation component 21. This positions the angle flipping component 22 between the direction rotation component 21 and the servo motor 231, reducing the length dimension of the slide rail component 232. This helps to reduce the size of the conveying component 23, thereby reducing the volume of the conveying mechanism 2 and ultimately miniaturizing the welding equipment 10.

[0061] Please see Figure 1 and Figure 4In some embodiments, the welding equipment 10 includes a vision inspection and robotic arm transfer mechanism 3, which is mounted on the frame 1 and located at one end of the transport mechanism 2.

[0063] Specifically, the front gripper 313 and the rear gripper 314 of the robotic arm simultaneously grip the coaxial cable on the angle flipping component 22 and then transport it to the vision inspection component 32 for inspection. After the inspection is completed, the front gripper 313 and the rear gripper 314 of the robotic arm simultaneously grip the coaxial cable that is judged to be OK and transport it to the welding mechanism 6. The front gripper 313 and the rear gripper 314 of the robotic arm simultaneously grip the coaxial cable that is judged to be NG and transport it to the designated position.

[0064] After the coaxial cable that has been inspected and determined to be OK is transported to the welding mechanism 6, according to the welding requirements, the front gripper 313 of the robot arm is released first, the robot arm 312 moves forward a certain distance, and finally the rear gripper 314 of the robot arm is released.

[0065] After the coaxial cable that was detected as NG is transported to the designated position, the front gripper 313 and the rear gripper 314 of the robot arm are released simultaneously, and the coaxial cable that was detected as NG is placed in the designated area.

The visual light source 324 is mounted on the visual light source mounting base 325 and is located on the side facing the visual camera mounting base 323.

[0067] Specifically, the coaxial cable can be placed between the visual light source 324 and the visual camera 322. The visual camera 322 detects the coaxial cable, including but not limited to length detection and position detection. The distance between the visual camera 322 and the visual light source 324 can be designed according to actual needs.

[0075] Please see Figure 6 In some embodiments, the transport and flipping mechanism 5 includes a transport component 51, an upper clamping component 52, and a lower clamping component 53. The upper clamping component 52 and the lower clamping component 53 are connected to the transport component 51. The upper clamping component 52 is located above the lower clamping component 53. The transport component 51 is used to drive the upper clamping component 52 and the lower clamping component 53 to move. The upper clamping component 52 and the lower clamping component 53 are used to clamp the circuit board.

[0076] Please see Figure 6In some embodiments, the transport assembly 51 includes a protective baffle 511, a lower clamp transport motor 512, an upper clamp transport motor 513, a motor fixing plate assembly 514, an upper clamp transport motor transmission component 515, a lower clamp transport motor transmission component 516, a linear slide rail fixing plate 517, a transport linear slide rail 518, and a transport bottom linear slide rail 519.

[0078] Similarly, the lower clamp transport motor 512 first drives the lower clamp assembly 53 from the automatic feeding and finished product unloading mechanism 4 along the first direction D1 towards the welding mechanism 6 to transport the circuit board to the welding mechanism 6 for welding. After welding is completed, the lower clamp assembly 53 is then driven from the welding mechanism 6 along the first direction D1 towards the automatic feeding and finished product unloading mechanism 4 to transport the circuit board assembly to the automatic feeding and finished product unloading mechanism 4. The upper clamp transport motor 513 and the lower clamp transport motor 512 simultaneously drive the upper clamp assembly 52 and the lower clamp assembly 53 to work, which can improve the transportation efficiency, thereby improving the welding efficiency.

[0079] Please see Figure 6 and Figure 7 In some embodiments, the upper clamping assembly 52 includes an upper clamping fixing platform 521, an upper rotary motor and transmission assembly 522, an upper rotary fixing platform 523, an upper rotary fixing platform fixing column 524, an upper adjustable limit plate 525, and an upper opening and closing cylinder assembly 526. The upper clamping fixing platform 521 is connected to the transport assembly 51. The upper rotary motor and transmission assembly 522 is connected to the upper clamping fixing platform 521 and the upper rotary fixing platform fixing column 524. The upper rotary fixing platform 523 is mounted on the upper clamping fixing platform 521 via the upper rotary fixing platform fixing column 524. The upper adjustable limit plate 525 and the upper opening and closing cylinder assembly 526 are mounted on the upper rotary fixing platform 523. The upper opening and closing cylinder assembly 526 is used to fix or release the circuit board. The upper rotary motor and transmission assembly 522 is used to drive the upper rotary fixing platform 523 to rotate.

[0080] Specifically, the upper clamping assembly 52 first moves to the automatic feeding and finished product unloading mechanism 4, clamps the circuit board from the automatic feeding and finished product unloading mechanism 4, and then moves to the welding mechanism 6. The upper rotary motor and transmission assembly 522 drives the upper rotary fixed platform 523 to rotate, so that the circuit board is in a vertical direction. The robotic arm handling assembly 31 clamps the coaxial line and passes the coaxial line through the circuit board. The welding mechanism 6 first welds the coaxial line to the first side of the circuit board. After the first side is welded, the upper rotary motor and transmission assembly 522 drives the upper rotary fixed platform 523 to rotate, so that the circuit board returns to its original horizontal direction, so that the welding mechanism 6 can weld the coaxial line to the second side of the circuit board to form a circuit board assembly. Finally, the upper clamping assembly 52 moves to the automatic feeding and finished product unloading mechanism 4 and releases the circuit board assembly.

[0081] Please see Figure 6 and Figure 7In some embodiments, the lower clamp assembly 53 includes a lower clamp fixing platform 531, a lower rotary motor and transmission assembly 532, a lower rotary fixing platform 533, a lower rotary fixing platform fixing column 534, a lower adjustable limit plate 535, a lower opening and closing cylinder assembly 536, a platform support upper and lower cylinders and linear bearing assembly 537, and an upper and lower cylinder fixing platform 538. The lower clamp fixing platform 531 is connected to the transport assembly 51 through the upper and lower cylinder fixing platform 538. The lower rotary motor and transmission assembly 532 is connected to the lower clamp fixing platform 531 and the lower rotary fixing platform fixing column 534. The lower rotary fixing platform 533 is connected to the transport assembly 51 through the lower clamp fixing platform 531 and the lower rotary fixing platform fixing column 534. The lower rotating fixed platform fixing column 534 is set on the lower clamping fixed platform 531, the lower adjustable limit plate 535 and the lower opening and closing cylinder assembly 536 are set on the lower rotating fixed platform 533. The lower opening and closing cylinder assembly 536 is used to fix or release the circuit board. The lower rotating motor and transmission assembly 532 is used to drive the lower rotating fixed platform 533 to rotate. The platform support upper and lower cylinder and linear bearing assembly 537 is set on the upper and lower cylinder fixed platform 538. One end of the platform support upper and lower cylinder and linear bearing assembly 537 is connected to the lower clamping fixed platform 531 and is used to drive the lower clamping fixed platform 531 to move along the second direction D2.

[0082] Specifically, the lower clamping assembly 53 first moves to the automatic feeding and finished product unloading mechanism 4, clamps the circuit board from the automatic feeding and finished product unloading mechanism 4, and then moves to the welding mechanism 6. The lower rotary motor and transmission assembly 532 drives the lower rotary fixed platform 533 to rotate, so that the circuit board is in a vertical direction. The robotic arm handling assembly 31 clamps the coaxial cable and passes the coaxial cable through the circuit board. The welding mechanism 6 first welds the coaxial cable to the first side of the circuit board. After the first side is welded, the lower rotary motor and transmission assembly 532 drives the lower rotary fixed platform 533 to rotate, so that the circuit board returns to its original horizontal direction, so that the welding mechanism 6 can weld the coaxial cable to the second side of the circuit board to form a circuit board assembly. Finally, the lower clamping assembly 53 moves to the automatic feeding and finished product unloading mechanism 4 and releases the circuit board assembly.

[0083] When welding the circuit board on the lower clamp assembly 53 to the coaxial line, the platform support upper and lower cylinders and linear bearing assembly 537 drives the lower clamp fixing platform 531 to move upward, so that the welding mechanism 6 can perform welding. When the lower clamp transport motor 512 drives the lower clamp assembly 53 to move along the first direction D1, the platform support upper and lower cylinders and linear bearing assembly 537 drives the lower clamp fixing platform 531 to move downward, so as to reduce the interference between the lower clamp assembly 53 and the upper clamp assembly 52.

[0084] Please see Figure 1 and Figure 8In some embodiments, the welding mechanism 6 includes a welding threading auxiliary mechanism 61, a first welding component 62, a welding combing mechanism 63, and a second welding component 64. The first welding component 62 and the second welding component 64 are spaced apart along a first direction D1. The second welding component 64 is located between the first welding component 62 and the automatic feeding and finished product unloading mechanism 4. The welding threading auxiliary mechanism 61 and the first welding component 62 are arranged opposite to each other along a third direction D3.

The threading guide cylinder 615 is used to assist in threading the coaxial cable through the soldering holes of the circuit board. The threading and positioning cylinder 614 is connected to the threading and positioning cylinders 616 through the threading and positioning cylinder fixing plate 618. The transport component 51 can be installed between the welding threading auxiliary mechanism 61, the first welding component 62, and the welding combing mechanism 63 and the second welding component 64.

[0086] Specifically, the threading cylinder 612 and the threading front and rear cylinder 613 respectively drive the threading guide cylinder 615 to move along the second direction D2 and the third direction D3. The threading cylinder 612, the threading front and rear cylinder 613 and the threading positioning cylinder 616 respectively drive the threading positioning cylinder 614 to move along the first direction D1, the second direction D2 and the third direction D3.

[0087] After the upper clamping assembly 52 or lower clamping assembly 53 moves to the welding mechanism 6, and the upper rotating fixed platform 523 or lower rotating fixed platform 533 rotates until the circuit board is vertical, the threading cylinders 612 and 613 first drive the threading positioning cylinder 614 and threading guide cylinder 615 to move closer to the upper clamping assembly 52 or lower clamping assembly 53. The robotic arm handling assembly 31 transports the coaxial cable to the welding threading auxiliary mechanism 61, so that the coaxial cable is threaded through the threading guide cylinder 615. The threading guide cylinder 615 provides guidance for the coaxial cable to pass through the welding hole of the circuit board. The threading positioning cylinder 614 fixes the coaxial cable from the robotic arm handling assembly 31 to facilitate welding. After the coaxial cable is welded, the threading positioning cylinder 614 and the threading guide cylinder 615 open, and the upper clamping assembly 52 or lower clamping assembly 53 moves a certain distance as required, after which the threading guide cylinder 615 closes. The welding and threading auxiliary mechanism 61 continuously repeats the above steps until the first side of an entire circuit board is welded. After welding, the threading upper and lower cylinders 612 and the threading front and rear cylinders 613 drive the threading positioning cylinder 614 and the threading guide cylinder 615 to move away from the upper clamp assembly 52 or the lower clamp assembly 53.

[0089] Specifically, the third direction D3 can be the width direction of the frame 1, and the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. The first welding front and rear lead screw motor and assembly 623 and the first welding up and down servo motor and assembly 624 can drive the welding up and down cylinder fixing plate 626 to move along the second direction D2 and the third direction D3 according to the welding position of the circuit board, so as to drive the first soldering iron handle 627 to move along the second direction D2 and the third direction D3.

[0090] The first welding front and rear lead screw motor and assembly 623 and the first welding up and down servo motor and assembly 624 first drive the first soldering iron handle 627 to move closer to the circuit board. Then, the first solder dispensing controller 629 controls the amount and speed of solder dispensing from the first soldering iron handle 627 to solder the coaxial cable and the first side of the circuit board. After the soldering is completed, the first welding front and rear lead screw motor and assembly 623 and the first welding up and down servo motor and assembly 624 drive the first soldering iron handle 627 away from the circuit board.

[0092] Specifically, the combing cylinder 632 first drives the combing groove fixing plate 634 to move closer to the circuit board along the second direction D2, so that the coaxial line is located in the combing groove 635. Then, the combing cylinder 633 drives the combing groove fixing plate 634 to move along the third direction D3 to flatten the coaxial line. After flattening, the combing cylinder 632 drives the combing groove fixing plate 634 to move away from the circuit board along the second direction D2.

The upper clamping component 52 or the lower clamping component 53 rotates the circuit board to the vertical direction. The welding wire threading auxiliary mechanism 61 assists in threading the coaxial cable through the circuit board. The first welding component 62 welds the coaxial cable to the first side of the circuit board. After welding is completed, the upper clamping component 52 or the lower clamping component 53 rotates the circuit board to the horizontal direction.
