[Specific implementation method]

[0050] Please refer to Figure 1-Figure 16 The present embodiment is a PCBA board assembly production line for a TCU controller. The PCBA board assembly production line 100 for the TCU controller includes a first conveyor line 101 for conveying a carrier 200 and a PCBA board, a shielding cover assembly machine 1, a cable assembly system, an antenna assembly system and a fan assembly machine 9 which are sequentially arranged along the conveying direction of the first conveyor line 101.

[0051] The feeding end of the first conveyor line 101 is connected to a carrier loader 103, and the discharging end is connected to a carrier unloader 104. A second conveyor line 102 for conveying carriers 200 and making the carriers circulate repeatedly is arranged below the first conveyor line 101. The two ends of the second conveyor line 102 are respectively connected to the carrier loader 103 and the carrier unloader 104. The carrier loader 103 and the carrier unloader 104 are both provided with a lifting conveyor line 105 for realizing the cyclic lifting and conveying of the carriers 200 between the first conveyor line 101 and the second conveyor line 102. After the products at the discharging end of the first conveyor line 101 are transported away, the empty carriers 200 are transported to the second conveyor line 102 through the carrier unloader 104, and the carriers 200 on the second conveyor line 102 are transported to the first conveyor line 101 through the carrier loader 103, and the products are loaded again, so that the cyclic use of the carriers 200 is realized.

[0052] The shielding cover assembly machine 1 includes a shielding cover feeding device 11 arranged on one side of the first conveyor line 101, a PCBA board feeding device 12 arranged on the other side of the first conveyor line 101, a flipping mechanism 13 arranged next to the PCBA board feeding device 12, a first lifting device 15 arranged between the first conveyor lines 101 and lifting the carrier 200, and a shielding cover conveying and assembling device 14 for conveying between the shielding cover feeding device 11, the PCBA board feeding device 12 and the flipping mechanism 13.

[0053] In this embodiment, since each PCBA board needs to be assembled with two shielding covers, in order to improve efficiency, two shielding cover feeding devices 11 are provided along the conveying direction of the carrier.

[0054] The shielding cover feeding device 11 and the PCBA board feeding device 12 both include a lifting feeding module 111, a first conveying module 112 connected to the lifting feeding module 111 and arranged horizontally, a transfer component 113 for transferring the material tray on the lifting feeding module 111 to the first conveying module 112, and a lifting and supporting component 114 arranged at the end of the first conveying module 212 to lift the material tray.

[0055] The two shielding covers are respectively assembled on the front and back sides of the PCBA board. Therefore, a flipping mechanism 13 is provided to flip the PCBA board. First, one shielding cover is assembled on the front side of the PCBA board, and the PCBA board is flipped by the flipping mechanism 13. Then, the other shielding cover is assembled on the back side of the PCBA board. The front and back sides of the PCBA board are both provided with a conforming matching structure that conforms to the shielding cover. The shielding cover transporting and assembling device 14 places the shielding cover in the correct position, and then presses down to complete the assembly of the shielding cover.

[0056] The flipping mechanism 13 includes a flipping positioning plate 131 for positioning the PCBA board, a rotating shaft 132 fixed to the back of the flipping positioning plate 131, a first motor 133 driving the rotating shaft 132 to rotate around a horizontal axis, a receiving plate 134 for receiving the PCBA board after the flipping positioning plate 131 is flipped, a first driving module 135 driving the receiving plate to lift and move horizontally, and a pressure sensor 136 arranged on the receiving plate 134.

[0057] The flip positioning plate 131 and the receiving plate 134 are both provided with a first positioning structure for positioning the PCBA board, and the first positioning structure includes a positioning pin and a suction hole.

[0058] The first driving module 135 includes a Y-axis linear motor 1351, a second support plate 1352 driven by the Y-axis linear motor 1351 to move in the Y direction, a tenth cylinder 1353 fixed on the second support plate 1352, and a first lifting frame 1354 driven by the tenth cylinder 1353 to move up and down, and the receiving plate 134 is fixed at the upper end of the first lifting frame 1354.

[0059] The shielding cover conveying and assembling device 14 includes a first gripper frame 141 arranged at the movable end of the manipulator, and the first gripper frame 141 is provided with a shielding cover adsorption component 142 for adsorbing the shielding cover, a first adsorption component 143 for adsorbing the PCBA board, and a first camera 144 for taking pictures of the shielding cover and the PCBA board.

[0060] The shield cover adsorption assembly 142 includes a third cylinder 1421 disposed on the first gripper frame 141, a first adsorption frame 1422 driven by the third cylinder 1421 to move up and down, and a first adsorption block 1423 disposed at the bottom of the first adsorption frame 1422. A first adsorption hole for vacuum adsorption is disposed on the first adsorption block 1423. Since a shield cover needs to be assembled on the front and back of the same PCBA board, two shield cover adsorption assemblies 142 are provided to adsorb two shield covers at a time, thereby improving work efficiency.

[0061] The first adsorption assembly 143 includes a fourth cylinder 1431 disposed on the first gripper frame 141, a second lifting frame 1432 driven by the fourth cylinder 1431 to move up and down, and a second adsorption block 1433 disposed on the second lifting frame 1432, wherein the second adsorption block 1433 is provided with a second adsorption hole for vacuum adsorption.

[0062] The front and back sides of the PCBA board are both provided with contoured matching structures for contoured positioning with the shielding cover. The shielding cover transporting and assembling device 14 places the shielding cover at the corresponding position on the PCBA board, and then the shielding cover transporting and assembling device 14 presses downward to complete the assembly of the shielding cover.

[0063] The shielding cover assembly machine 1 is also provided with a first CCD inspection camera 16. When the shielding cover transporting and assembling device 14 adsorbs the PCB board 300 and assembles the shielding cover, the positions of the PCB board 300 and the shielding cover must be inspected before placing the PCB board 300 and assembling the shielding cover to ensure the accuracy of the shielding cover assembly position.

[0064] The working process of the shielding cover assembly machine 1 is as follows: the shielding cover transporting and assembling device 14 moves to the shielding cover feeding device 11, the two shielding cover adsorption components 142 successively adsorb one shielding cover each and move to the PCBA board feeding device 12, the first adsorption component 143 adsorbs one PCBA board, the shielding cover transporting and assembling device 14 moves to the flipping mechanism 13, and places the PCBA board with the front side facing up on the flip positioning plate 131, one of the shielding cover adsorption components 142 of the shielding cover transporting and assembling device 14 assembles the shielding cover to the front side of the PCBA board, the first motor 133 drives the rotating shaft 132 to rotate and drive the flip positioning plate 131 to flip 180°, and at the same time, the Y-axis linear motor 1351 of the first driving module 135 drives the second supporting plate 1352 to drive the receiving plate 134 to move to the flipping position. Directly below the positioning plate 131, the tenth cylinder 1353 drives the first lifting frame 1354 to drive the receiving plate 134 to rise to receive the PCBA board that has been flipped 180° and fallen from the flip positioning plate 131. The back of the PCBA board is positioned on the receiving plate 134 with its back facing upward. Another shielding cover adsorption component 142 of the shielding cover transporting and assembling device 14 assembles the shielding cover to the back of the PCBA board. At the same time, the pressure sensor 136 detects the pressure during assembly to ensure that the shielding cover 400 can be smoothly assembled to the back of the PCBA board. The first adsorption component 143 of the shielding cover transporting and assembling device 14 adsorbs the PCBA board and transports it to the carrier 200. The first jacking device 15 drives the carrier 200 to descend. The carrier 200 is located on the first conveyor line 101 and flows into the cable assembly system via the first conveyor line 101.

[0065] The cable assembly system includes a cable assembly machine 2 arranged along the conveying direction for assembling the cable onto the PCBA board, a cable press-fitting machine 3 for press-fitting the female connector at the end of the cable onto the PCBA board, and a cable detection device 4 for detecting the assembled cable.

[0066] Since different components will be assembled on the PCBA board, when assembling the antenna, in order to avoid other components, the cables will form different directions. Therefore, multiple antennas on the PCBA board will have different directions. In this embodiment, four cables of different lengths and directions need to be assembled on the back of the PCBA board. In order to improve the assembly efficiency of the cables, four cable assembly machines 2 are sequentially arranged along the conveying direction, and each cable assembly machine 2 assembles one cable.

[0067] The cable assembly machine 2 includes a cable installation frame 21 arranged above the first conveyor line 101, a cable positioning plate 22 that is three-dimensionally floatingly arranged on the cable installation frame 21 and positions the cable, a pressure rod 23 that presses the cable to be assembled onto the PCBA board via the cable positioning plate 22, and a second lifting device 24 that is arranged between the first conveyor lines 101 and lifts the carrier 200.

[0068] Since the positions of the carrier and the PCBA board may have slight deviations, in order to ensure that the cable can be smoothly assembled on the PCBA board on the cable positioning plate 22, a three-dimensional floating structure 25 is provided on the cable mounting frame 21 to enable the cable positioning plate 22 to float three-dimensionally. The three-dimensional floating structure 25 includes a pair of first moving rods 251 disposed at both ends of the cable mounting frame 21 and floating along the Z direction, a pair of second moving rods 252 disposed on the first moving rods 251 and floating along the X direction, and a pair of third moving rods 253 disposed on the second moving rods 252 and floating along the Y direction, and both ends of the cable positioning plate 22 are disposed on the third moving rods 253.

[0069] The first moving rod 251 is movably set on the cable mounting frame 21 through a plurality of first linear bearings 254 in the Z direction, the second moving rod 252 is movably set on the first moving rod 251 through a plurality of second linear bearings 255 in the X direction, and the third moving rod 253 is movably set on the second moving rod 252 through a plurality of third linear bearings 256 in the Y direction. The first moving rod 251, the second moving rod 252 and the third moving rod 253 are set in parallel.

[0070] The cable positioning plate 22 is provided with a cable profiling hole 221 that conforms to the direction of the cable, which limits the direction of the wire and facilitates smooth installation of the cable from the cable profiling hole 221 to the PCBA board, thereby improving the efficiency of cable assembly.

[0071] The pressure rod 23 is arranged beside the cable mounting frame 21, and a support frame for placing the pressure rod 23 is arranged on the cable mounting frame 21; the pressure rod 23 is in the shape of a pen, and a pressure needle which can be inserted into the cable profiling hole 221 is arranged at the lower end of the pressure rod 23.

[0072] The cable press-fitting machine 3 is provided with a press-fitting module 31 and a third lifting device 32 for lifting the carrier 200 .

[0073] In this embodiment, since four cables are assembled and the female connectors at the ends of the cables need to be pressed onto the male connectors of the PCBA board to achieve electrical conduction between the cables and the PCBA board, in order to improve the efficiency of pressing, two pressing modules 31 are provided in the eye conveying direction to press different cables respectively.

[0074] The press-fitting module 31 includes a first XY axis driving module 311, a first support plate 312 driven by the first XY axis driving module 311 to move in the XY direction, a first cylinder 313 fixed on the first support plate 312, a torque sensor 314 driven by the first cylinder 313 to move up and down, and a press-fitting needle 315 fixed at the lower end of the torque sensor 314. The bottom of the press-fitting needle 315 is configured to conform to the upper surface of the female connector at the end of the cable. In this embodiment, the upper surface of the female connector at the end of the cable is a plane, so the press-fitting needle 315 is configured to be rod-shaped and the bottom is a plane.

[0075] The cable detection device 4 includes a 2D detection module 41 for detecting whether the cable pressing appearance and pressing position are qualified, a 3D detection module 42 for detecting whether the pressing height of the female connectors at both ends of the cable is qualified, and a second XY axis driving module 43 for driving the 2D detection module 41 and the 3D detection module 42 to move along the XY direction.

[0076] The working process of the cable assembly system is as follows: when the PCBA board flows to the first cable assembly machine 2 via the first conveyor line 101, the second lifting device 24 lifts up the carrier 200, fine-tunes the cable positioning plate 22 to align the cable profiling hole 221 with the position of the PCBA board below where the cable needs to be assembled, places the first cable in the cable profiling hole 221, presses the cable downward using the pressure needle of the pressure rod 23, and makes the middle of the cable snap into the buckles of the PCBA board at multiple locations, drives the carrier 200 to descend by the second lifting device 24, and the carrier 200 is located on the first conveyor line 101 and flows into the next cable assembly machine 2 via the first conveyor line 101, and in the same way, assembles the second cable, the third cable and the fourth cable to the corresponding positions of the PCBA board in turn, and after the four cables are assembled, drives the second lifting device 24 to The carrier 200 descends, the carrier 200 is located on the first conveyor line 101 and flows into the cable press-fitting machine 3 through the first conveyor line 101, the third lifting device 32 lifts the carrier 200, and the pressing needles 315 of the two pressing modules 31 respectively press the female head of the cable end into the male head of the PCBA board, and the torque sensor 314 controls the pressure of the pressing needle 315 to ensure that the female head of the cable end is smoothly pressed into the male head of the PCBA board. After the pressing is completed, the second lifting device 24 drives the carrier 200 to descend, the carrier 200 is located on the first conveyor line 101 and flows into the cable detection device 4 through the first conveyor line 101, the 2D detection module 41 detects the appearance and position of the cable pressing, and the 3D detection module 42 detects the height of the female head pressing at both ends of the cable. After the detection is completed, it flows into the antenna assembly system.

[0077] The antenna assembly system includes an antenna loader 5 arranged along the conveying direction, an antenna assembly machine 6 for assembling the antenna onto the PCBA board, an antenna welding machine 7 for welding the antenna onto the PCBA board, and an antenna inspection machine 8 for inspecting the welded antenna.

[0078] Three pairs of six antennas need to be assembled on the front of the PCBA board. The six antennas are assembled at the ends and both sides of the PCBA board. After assembly, the antennas need to be welded to the PCBA board. Since the cable assembly system is pressed and installed, the back of the PCBA board is facing up. Therefore, the antenna loader 5 first moves the antenna to the carrier 200, and then the antenna assembly machine 6 places the PCBA board on the antenna to complete the assembly operation, and all the pins of the antenna are facing up, and then the antenna welding machine 7 is used to weld the pins of the antenna to the back of the PCBA board. Therefore, the carrier 200 is provided with a first positioning structure 201 for positioning the PCBA board, and a second positioning structure 202 for positioning the six antennas.

[0079] The antenna includes a first antenna 301 with a larger size and a second antenna 302 and a third antenna with smaller sizes. The first antenna 301, the second antenna 302 and the third antenna are arranged in pairs. Therefore, two antenna loaders 5 are arranged along the conveying direction. Each antenna loader 5 completes the loading of the first antenna 302, the second antenna 302 and the third antenna. The third antenna is located next to the first antenna 301 and at both ends of the second positioning structure 202.

[0080] The antenna loader 5 includes an antenna feeding device 51 , an antenna transporting device 54 for transporting antennas, and a fourth lifting device 53 for lifting the carrier 200 .

[0081] Since the three antennas have different appearances and structures, three antenna feeding devices 51 are used, namely a first feeding device 511 for the first antenna, a second feeding device 512 for the second antenna, and a third feeding device 513 for the third antenna.

[0082] The first feeding device 511 has the same structure as the shielding cover feeding device 11 and the PCBA board feeding device 12, except that the structure of the material tray is slightly changed. The positioning structure in the material tray is changed accordingly according to different products, which will not be elaborated here.

[0083] The second feeding device 512 and the third feeding device 513 both adopt a vibration disk loading method, and the second feeding device 512 and the third feeding device 513 both include a vibration disk with an output pin facing upward, a horizontal flow channel 5122 connected to the vibration disk, a dividing plate 5123 movably arranged at the end of the horizontal flow channel 5122, a fifth cylinder 5124 for driving the dividing plate 5123 to connect or disconnect with the horizontal flow channel 5122, a return plate 5125 movably arranged at one side of the horizontal flow channel 5122 and for returning the second antenna or the third antenna, and a sixth cylinder 5126 for driving the return plate 523 to move forward and backward.

[0084] The antenna transport device 54 includes a second gripper frame 541 arranged at the movable end of the manipulator, a transport module for transporting the antenna is arranged on the second gripper frame 541, and a second CCD detection camera 546 for detecting the position of the antenna. The transport module includes an antenna adsorption component 542 for adsorbing the first antenna, a first clamping component 543 for clamping the second antenna, and a second clamping component 544 for clamping the third antenna.

[0085] The antenna adsorption assembly 542 includes a seventh cylinder 5421, a third adsorption frame 5422 driven by the seventh cylinder 5421 to move up and down, and a third adsorption block 5423 fixed to the lower end of the third adsorption frame 5422, and the third adsorption block 5423 is provided with a third adsorption hole for vacuum adsorption.

[0086] The first clamping assembly 543 and the second clamping assembly 544 both include an eighth cylinder 5431, a third lifting frame 5432 driven by the eighth cylinder 5431 to move up and down, a ninth cylinder 5433 fixed on the third lifting frame 5432, and a pair of first clamping claws 5434 driven by the ninth cylinder 5433 to clamp or open.

[0087] The antenna assembly machine 6 includes an antenna positioning device 61 for positioning the antenna, an antenna transfer table 62 for temporarily placing the PCBA board, a transport device 63 for transporting the PCBA board, a fifth lifting device 64 for lifting the carrier 200 , and a third CCD detection camera 65 .

[0088] The antenna positioning device 61 includes two movable mounting plates 611 movably arranged above the carrier 200 and located on the front and rear sides of the carrier 200, two second motors 612 respectively driving the two movable mounting plates 611 to move closer to or away from each other, a plurality of second cylinders 613 arranged on the movable mounting plates 611, and second clamps 614 driven by the second cylinders 613 to clamp the ends of the antennas and align the antennas. Multiple pairs of second clamps 614 are clamped on the ends of the antennas at the same time and align the antennas, so that when the transport device 63 places the PCBA board above the antennas, the three pairs of antennas can be smoothly assembled on the PCBA board. At this time, the pins of the antennas are all inserted into the welding holes of the PCBA board, and the antenna welding machine 7 welds the pins to the PCBA board.

[0089] The antenna transfer platform 62 is provided with a first positioning structure for positioning the PCBA board. The antenna transfer platform 62 is provided for temporarily placing the PCBA board. Since the antenna positioning device 61 blocks the PCBA board on the carrier 200, it is necessary to take out the PCBA board on the carrier 200 in advance and place it on the antenna transfer platform 62. After the second clamps 614 of the antenna positioning device 61 have positioned the antenna, the PCBA board on the antenna transfer platform 62 is directly placed on the second positioning structure 202 on the carrier 200, and the antenna pins are inserted into the welding holes of the PCBA board. At the same time, the lower surface of the PCBA board is positioned on the support block of the second positioning structure 202.

[0090] The transport device 63 includes a third gripper frame 631 disposed at the movable end of the manipulator and a fourth adsorption block 632 disposed at the lower end of the third gripper frame 631 . The fourth adsorption block 632 is provided with a fourth adsorption hole for vacuum adsorption.

[0091] Since each antenna is provided with a plurality of pins, and there are a total of six antennas that need to be welded, in order to improve the welding efficiency, three antenna welding machines 7 are provided along the conveying direction to weld different pins of the antennas respectively.

[0092] The antenna welding machine 7 includes a welding positioning plate 71 disposed above the carrier 200 and used to position the welding position, a welding gun 72 disposed above the welding positioning plate 71 and used to weld the antenna to the PCBA board, and a sixth lifting device 73 for lifting the carrier 200 from the first conveyor line 101 .

[0093] The welding positioning plate 71 is provided with a plurality of positioning through holes 711 corresponding to the welding positions and for the welding gun 72 to extend into. Since the three antenna welding machines 7 respectively weld different pins of the antenna, the position and shape of the positioning through holes 711 on the welding positioning plate 71 of each antenna welding machine 7 are adapted to different pins, which are not limited here. A circle of silicone is provided on the outside of the positioning through holes 711 on the back of the welding positioning plate 71, so that when the welding positioning plate 71 is pressed tightly against the PCBA board, the silicone is in soft contact with the PCBA board to prevent the PCBA board from being crushed.

[0094] The antenna inspection machine 8 is provided with a fourth CCD inspection camera 81 for inspecting solder on the PCBA board.

[0095] The working process of the antenna assembly system is as follows: the carrier 200 carries the PCBA board with assembled cables to the first antenna loader 5 via the first conveyor line 101, and the antenna handling device 54 of the first antenna loader 5 sequentially absorbs or clamps an antenna from the first feeding device 511, the second feeding device 512 and the third feeding device 513 and places them on the second positioning structure on the carrier 200 in turn. The second antenna loader 5 also places the other three antennas 300 on the third positioning structure on the carrier 200. On the second positioning structure, the fourth lifting device 53 drives the carrier 200 to descend and transports it to the antenna assembly machine 6 via the first conveyor line 101. The fifth lifting device 64 lifts the carrier 200 but is located below the mobile mounting plate 611. The transport device 63 transports the PCBA board on the carrier 200 to the antenna transfer table 62. The two second motors 612 drive the mobile mounting plate 611 to approach respectively. The second cylinder 613 drives the second clamping claw 614 to clamp the end of the antenna and correct the antenna. The transport device 63 The PCBA board on the antenna transfer table 62 is moved to the top of the antenna, and the three pairs of antennas can be smoothly assembled on the PCBA board. At this time, the pins of the antenna are all inserted into the welding holes of the PCBA board. The fifth lifting device 64 drives the carrier 200 to descend and fall on the first conveyor line 101. At the same time, the third CCD detection camera 65 detects whether the pins of the antenna are all inserted into the welding holes of the PCBA board. The carrier 200 flows through the first antenna welding machine 7. The sixth lifting device 73 lifts the carrier 200 and contacts the welding positioning plate 71. The silicone on the lower side of the welding positioning plate 71 is in soft contact with the PCBA board. The welding gun 72 moves to the positioning through hole 711 and welds the pins of the antenna to the PCBA board. The carrier flows through the second antenna welding machine 7 and the third antenna welding machine 7 in turn. The same actions as above are used to complete the assembly welding of the antenna and the PCBA board. After the welding is completed, the fourth CCD detection camera 81 detects the soldering condition on the PCBA board. After the detection is completed, the carrier 200 is conveyed to the fan assembly machine 9.

[0098] The positioning assembly 912 includes a twelfth cylinder 9121, a third support plate 9122 driven by the twelfth cylinder 9121 to move up and down, a force-controlled motor 9123 fixed on the third support plate 9122, and a positioning claw 9124 arranged at the end of the force-controlled motor 9123 and moved in a horizontal direction by the force-controlled motor 9123, and the positioning claw 9124 is provided with an avoidance opening for avoiding the antenna.

[0099] The working principle of the fan assembly machine 9 is as follows: the fan is manually placed on one end of the PCBA board, the eleventh cylinder 9112 drives the contour pressing plate 9111 to descend and press on the other end of the PCBA board, the twelfth cylinder 9121 drives the third support plate 9122 to descend, and the force control motor 9123 drives the positioning claw 9124 to position and assemble the fan on one end of the PCBA board. The force control motor 9123 can accurately control the clamping force of the positioning claw 9124, which can improve the accuracy of fan installation.

The first adsorption component 143 adsorbs a PCBA board, and then moves to the flip mechanism 13, and places the PCBA board with the front side facing up on the flip positioning plate 131. The shield cover adsorption component 142 assembles one of the shield covers to the front of the PCBA board, and the first motor 133 drives the rotating shaft 132 to rotate and drive the flip positioning plate 131 to flip 180°. At the same time, the first driving module 135 drives the receiving plate 134 to move to the flip positioning plate 13 1, to receive the PCBA board that has been flipped 180° and dropped from the flip positioning plate 131, and the back of the PCBA board is positioned on the receiving plate 134 with the back facing upwards, and the shield cover adsorption component 142 assembles another shield cover to the back of the PCBA board, and at the same time, the pressure sensor 136 detects the pressure during assembly to ensure that the shield cover can be smoothly assembled to the back of the PCBA board, and the first adsorption component 143 carries the PCBA board to the product carrier, and the lifting device drives the product carrier to descend, and the product carrier is located on the first conveyor line 101 and flows into the first cable assembly machine 2 through the first conveyor line 101, and the lifting device lifts the product carrier, and fine-tunes the cable positioning plate 22 so that the cable profiling hole 221 of the cable positioning plate 22 is aligned with the PCBA board below.

The product carrier is located on the conveyor line and flows into the three cable assembly machines 2 at the back through the conveyor line. In the same way, assemble the second cable, the third cable and the fourth cable to the corresponding positions on the PCBA board in turn. After the four cables are assembled, the product carrier drives the PCBA board to flow into the two pressing modules 31 on the cable pressing machine 3, and the lifting device lifts the product carrier. The first XY-axis driving module 311 drives the pressing needle 315 to move and press the female connectors at the ends of the cables into the PCBA board respectively. On the male head, the torque sensor 314 controls the pressure of the press-fitting needle 315 to ensure that the female head at the end of the cable is smoothly pressed into the male head of the PCBA board. After the press-fitting modules 31 are all press-fitted, the lifting device drives the product carrier to descend. The product carrier is located on the conveyor line and flows into the cable detection device 4 through the conveyor line. The 2D detection module 41 detects the appearance and position of the cable press-fitting.
