[0023] Please see Figures 1 to 23 As shown, this application provides a flexible pin insertion machine for connectors, including a plastic shell feeding mechanism 10 for automatically feeding plastic shells 1. A plastic shell positioning mechanism 20 is located beside the output end of the plastic shell feeding mechanism 10, used for positioning the plastic shell 1, and cooperates with the pin insertion mechanism 40 to insert pins into the plastic shell 1. A terminal group feeding and bending mechanism 30 is used for feeding terminal groups 2, bending the insertion ends of the terminal groups, and cutting the terminal groups 2 to a preset length. The pin insertion mechanism 40 is located beside the output end of the terminal group feeding and bending mechanism 30 and is arranged opposite to the plastic shell positioning mechanism 20. The pin insertion mechanism 40 picks up the terminal groups processed by the terminal group feeding and bending mechanism 30 and cooperates with the plastic shell positioning mechanism 20 to insert the cut terminal groups into the plastic shell 1.

[0024] A strip cutting mechanism 50, located beside the pin insertion mechanism 40, is used to cut the terminal group strip 3. A solder lead bending mechanism 60, located beside the strip cutting mechanism 50, is used to bend the solder end (strip end) of the terminal group to form a solder lead. A semi-finished product positioning mechanism 70, located beside the solder lead bending mechanism 60, is used to position the semi-finished product after the solder lead is bent; its function is basically the same as that of the plastic shell positioning mechanism 20. A shielding sheet insertion and removal mechanism 80, located opposite to the semi-finished product positioning mechanism 70, is used to feed, insert, and remove the shielding sheet strip 5 from the shielding sheet 4. A unloading mechanism 90, located beside the output end of the shielding sheet insertion and removal mechanism 80, unloads the processed connector.

[0025] The plastic shell feeding mechanism automatically feeds the plastic shells, while the terminal group feeding and bending mechanism feeds the terminal groups, bends the terminal group connectors, and cuts them to a preset length. The plastic shell positioning mechanism and the pin insertion mechanism work together to insert the terminal groups into the plastic shells. The strip cutting mechanism automatically cuts and removes the terminal strip. The solder foot bending mechanism bends the solder ends of the soldering terminal groups to form solder feet. The semi-finished product positioning mechanism and the shielding sheet insertion and removal mechanism work together to feed, cut, insert, and remove the shielding sheet strip. Finally, the unloading mechanism unloads the finished connectors. The entire processing is fully automated, greatly improving production efficiency.

[0026] In one embodiment, the plastic shell feeding mechanism 10 includes: a storage bin 11, a vibratory feeder 12, a first CCD camera 13, a feeding robot 14, a second CCD camera 16, and a conveying track assembly 15. The vibratory feeder 12 is located beside the output end of the conveying storage bin 11; the first CCD camera 13 is located above the vibratory feeder; the feeding robot 14 is located beside the vibratory feeder and is connected between the vibratory feeder and the conveying track assembly 15. The storage bin 11 is used to store plastic shells. When the number of plastic shells in the vibratory feeder 12 is insufficient (the central control mechanism can determine this based on the image data from the CCD camera 13 and can automatically feed the shells according to the set feeding time), the storage bin 11 automatically feeds the plastic shells into the vibratory feeder 12; the vibratory feeder 12 is used to vibrate and flip the plastic shells. The first CCD camera 13 is used to photograph and identify the plastic shells 1 in the vibratory feeder 12. After photographing the plastic shells 1, the first CCD camera 13 identifies the front and back or angle of the plastic shells. The loading robot 14 picks up the plastic shell 1 that has passed through the vibratory feeder 12. Preferably, the picking method is negative pressure suction. The loading robot 14 is a multi-axis robot, capable of multi-angle and multi-dimensional movement. The loading robot 14 places the picked-up plastic shell 1 onto the conveyor track assembly 15. A second CCD camera 16 is located beside the loading robot 14. The second CCD camera 16 is used to identify the angle of the plastic shell on the loading robot 14. The loading robot 14 adjusts the angle of the plastic shell according to the information identified by the second CCD camera 16.

[0027] The conveying track assembly 15 includes: a mounting frame 151, a track 152, a push motor 153, a push block 154, an adjusting motor 155, a material-picking cylinder 156, and a material-picking nozzle 157. The track 152 is slidably and adjustablely mounted on the mounting frame 151. The plastic shell is placed inside the track 152, and the height of the plastic shell 1 is higher than the height of the track 152 to facilitate pushing by the push block 154. The push motor 153 is mounted on the mounting frame 151; the push block 154 is connected to the output end of the push motor, and the push motor drives the push block to slide on the track, pushing the plastic shell for conveying. The adjusting motor 155 is mounted on the mounting frame 151 and connected to the track 152. The adjusting motor 155 drives the track 152 to the upper position of the mounting frame. A sensor is provided on the side of the picking nozzle 157 to sense whether the plastic shell is in place. By adjusting the position of the track 152, it can be adapted to the sensor to sense different models of plastic shells, thus achieving high versatility. The picking cylinder 156 is located above the end of the track. The picking nozzle 157 is connected to the output shaft of the picking cylinder 156. The picking cylinder 156 drives the picking nozzle 157 to move up and down at the end of the track. The picking cylinder 156 also drives the picking nozzle 157 to press down and pick up the plastic shell at the end of the track.

[0028] When the plastic shell feeding mechanism 10 is working, the storage bin 11 feeds the plastic shells onto the vibratory feeder 12. The first CCD camera 13 takes pictures of the plastic shells on the vibratory feeder 12. The central control system identifies which plastic shells 1 have their suction surfaces facing upwards based on the pictures, and controls the feeding robot 14 to pick up the corresponding plastic shells 1. When there are not many plastic shells with their suction surfaces facing upwards in the vibratory feeder 12, the central control system controls the vibratory feeder to vibrate, flipping the remaining plastic shells over. The feeding robot 14 moves the plastic shells 1 above the second CCD camera 16, and the second CCD camera 16 takes pictures of the angle of the plastic shells on the feeding robot 14. The central control system then controls the feeding robot 14 to... 14. Rotate and adjust the angle of the plastic shell, and the loading robot 14 will place the plastic shell on the track 152. The push motor 153 drives the push block 154 to move, moving the plastic shell on the track 152 toward the material pick-up nozzle 157. After the plastic shell is in place, the material pick-up cylinder 156 drives the material pick-up nozzle 157 to move down, and the material pick-up nozzle 15 picks up the plastic shell. Then, the material pick-up cylinder 156 drives the material pick-up nozzle 157 to move up until the plastic shell positioning mechanism 20 receives the material. After the material pick-up nozzle 157 places the plastic shell on the plastic shell positioning mechanism 20, it will blow air on the plastic shell to stably place the plastic shell on the plastic shell positioning mechanism 20.

[0029] In one embodiment, the plastic shell positioning mechanism 20 includes a forward / backward moving linear module 21, a vertical moving linear module 22, a horizontal moving linear module 23, a flipping component 24, and a positioning component 25.

The horizontal moving linear module 23 is located at the output end of the vertical moving linear module 22, and the vertical moving linear module 22 drives the horizontal moving linear module 23 to move up and down. The forward / backward moving linear module 21, the vertical moving linear module 22, and the horizontal moving linear module 23 work together to complete the forward / backward, horizontal / leftward / upward / downward movement of the plastic shell.

[0030] The flipping component 24 is located at the output end of the left-right moving linear module 23. The left-right moving linear module 23 drives the flipping component 24 to move left and right. When the terminal group 2 to be inserted into the plastic shell is double-row and the double-row terminals need to be mirrored, the flipping component 24 drives the plastic shell to flip 180° to adapt to the pins of different types of connectors. The flipping component 24 includes an adjusting motor 241 and a rotating shaft 242 located on the output shaft of the adjusting motor. The positioning component 25 includes a positioning seat 251, a positioning claw 252, a positioning cylinder 253, and a contour block 254. The positioning seat 251 is located on the output shaft of the adjusting motor and rotates with the output shaft of the adjusting motor. There are two positioning claws 252, which are spaced apart at the end of the positioning seat near the pin mechanism 40. A positioning space 201 for positioning the plastic shell is formed between the two positioning claws. The positioning cylinder 253 is mounted on the positioning seat; the contour block 254 is mounted on the output shaft of the positioning cylinder. The positioning cylinder drives the contour block to extend and insert into the plastic shell for support, preventing the plastic shell from sinking inward.

[0031] When the plastic shell positioning mechanism 20 is working, the forward and backward moving linear module 21 drives the flipping component 24 to move towards the conveying track component 15. After reaching the preset position, the picking cylinder 156 drives the picking nozzle 157 to move down and put the plastic shell into the positioning space 201. The forward and backward moving linear module 21 and the up and down moving linear module 22 drive the flipping component 24 to move and adjust the position. Then, the left and right moving linear module 23 drives the plastic shell to move towards the pin insertion mechanism 40 to insert the pin.

The upper cylinder 342 is located above the output end of the second needle feed track 341, and the mounting block 343 is disposed on the output shaft of the upper cylinder 342. There are multiple positioning cones 344, which are spaced apart on the mounting block 343 and connected to the mounting block 343 by springs. The positioning cones 344 are inserted into the first material strip hole 6 for flexible positioning. The first cutting pin 347 is located on the mounting block near the output end of the second needle feed track 341. The upper cylinder 342 drives the first cutting pin 347 to press down, pressing it onto the material strip of the terminal group 2 and cutting the material strip. There is a height difference between the first cutting pin 347 and the positioning cone 344.

[0038] When the cutting assembly 34 is working, the upper cylinder 342 drives the mounting block 343 and the positioning cone 344 to press down, and the lower cylinder 345 drives the top cutting block 346 to push up. After the terminal group is pressed, the terminal group strip is cut off under the force of the first cutting nail 347 and the top cutting block 346.

[0039] The needle feeding assembly 35 is disposed opposite to the cutting assembly 34; the needle feeding assembly includes a needle feeding cylinder 351, a needle feeding slide 352, and a gripper cylinder 353; the needle feeding cylinder 351 drives the needle feeding slide 352 to slide back and forth, thereby realizing the feeding of the cut terminal group.

[0040] When the needle feeding assembly 35 is working, the gripper cylinder 353 drives the needle gripper 354 to grip the plug end of the terminal group (at this time, the terminal group has been cut by the cutting assembly 34). Then, the needle feeding cylinder 351 drives the needle feeding slide 352 to transport the cut terminal group to the needle insertion mechanism 40, and delivers the cut terminal group to the needle insertion mechanism.

[0041] In another embodiment, if the connector is a double-row terminal connector, then there are two terminal group feeding and bending mechanisms 30, with the two terminal group feeding and bending mechanisms 30 arranged back and forth at intervals, and the two feeding each other in a cross manner.

[0042] In one embodiment, the pin insertion mechanism 40 includes a guide assembly 41 and a positioning pin assembly 42.

[0043] The abutment block 424 and the pin block 425 are respectively disposed on the pin cylinder 423. The pin cylinder 423 drives the abutment block 424 and the pin block 425 to move closer or further away from each other, thereby clamping and releasing the multi-terminal group. The rear end face of the abutment block 424 is flat and is used to abut against the end of the terminal group material strip. The front end face of the pin block 425 is recessed with a first groove 401 that is adapted to the end of the terminal group material strip. The first groove 401 plays a positioning role. The abutment block 424 and the pin block 425 clamp the end of the terminal group material strip. The insertion end of the terminal group extends forward from the front end face of the abutment block 425, that is, towards the positioning component 25.

[0044] The guide component 41 is located above the positioning pin component 42. The wire component 41 includes a guide cylinder 411 and a guide block 412 connected to the output end of the guide cylinder 411. The guide block 412 has a second groove 402 that matches the bending position of the terminal group. The guide cylinder drives the guide block 412 to press down, so that the bending position of the terminal group is pressed into the second groove 402. In addition to guiding the terminal group during insertion, the guide block 412 also effectively prevents the terminal group from tilting upward.

[0045] When the pin insertion mechanism 40 is working, the drive cylinder 421 first drives the abutment block 424 and the pin insertion block 425 to rotate, so that the pin assembly 35 is delivered to the terminal group position. The pin insertion cylinder 423 drives the abutment block 424 and the pin insertion block 425 to clamp the terminal group 2. The drive cylinder 421 drives the terminal group 2 to rotate so that the terminal group insertion end faces the positioning component 25. Then, the guide cylinder 411 drives the guide block 412 to press down and press the terminal group insertion end for guidance. Then, the plastic shell positioning mechanism 20 drives the plastic shell 1 to move towards the terminal group insertion end for the first time, pre-inserting the terminal group insertion end into the plastic shell 1. The guide cylinder 411 drives the guide block 412 to rise and no longer press the terminal group. Finally, the plastic shell positioning mechanism 20 drives the plastic shell 1 to move towards the terminal group insertion end for the second time, fully inserting the terminal group insertion end into the plastic shell 1.

The semi-finished product positioning mechanism 70 drives the end of the terminal group material strip to insert between the upper bending block 65 and the lower bending block 63. The bending motor 61 drives the lower bending block 63 to rotate, bending the end of the terminal group material strip to form a welding foot.

[0048] When the welding foot bending mechanism 60 is working, the second transfer component 102 delivers the semi-finished connector to the welding foot bending mechanism 60 and extends the material strip end (welding end) of the terminal group between the upper bending block 65 and the lower bending block 63; the bending motor 61 drives the rotating frame 62 to rotate the upper and lower bending blocks 63, bending the material strip end of the terminal group along the upper bending block 65 to form a welding foot.
