[0047] Specifically, in the present embodiment, when the needle seat, the support rod, the movable plate and the spring are assembled, the turntable 110 of the cam divider 100 drives the jig 120 to rotate, and the jig 120 will first rotate to the needle seat feeding mechanism 200 during the rotation process, and the needle seat feeding mechanism 200 will clamp the needle seat and place it in the jig 120. After the needle seat is automatically fed, the turntable 110 rotates with the jig 120 to the support rod feeding mechanism 300, and the support rod feeding mechanism 300 clamps the support rod and places it in the jig 120, so that the support rod cooperates with the needle seat. After the support rod is automatically fed, the turntable 110 rotates with the jig 120 to the movable plate feeding mechanism 400, and the movable plate feeding mechanism 400 sucks the movable plate and places it in the jig 120, so that the movable plate, the needle seat and the support rod are engaged with each other. After the movable plate is automatically loaded, the turntable 110 rotates with the jig 120 to the spring loading mechanism 500, and the spring loading mechanism 500 clamps the spring and places it in the jig 120, and makes the spring cooperate with the support rod and the movable plate respectively. After the spring is automatically loaded, the turntable 110 rotates with the jig 120 to the assembly mechanism 600, and the support rod, movable plate, spring and needle seat are assembled through the assembly mechanism 600. After the assembly is completed, the turntable 110 rotates with the jig 120 to the discharging mechanism 700, and the discharging mechanism 700 automatically unloads the assembled needle seat, support rod, movable plate and spring, thereby completing the automated assembly of the needle seat, support rod, movable plate and spring.

The above two detection mechanisms 800 are not limited to visual detection and laser sensors, and other detection mechanisms in the prior art can also be used.

[0049] See also Figure 4 In order to realize automatic loading of the needle seat, the needle seat loading mechanism 200 in this embodiment includes a needle seat conveying channel 210, a needle seat CCD detection unit 220 and a needle seat PPU manipulator 230. The needle seat conveying channel 210 is used to convey the needle seat. The needle seat CCD detection unit 220 is arranged at the tail end of the needle seat conveying channel 210.

The needle seat PPU manipulator 230 drives the needle seat clamp 240 to clamp the needle seat at the tail end of the needle seat conveying channel 210 to the fixture 120.

[0050] When the needle seat is automatically loaded, the vibration disk will vibrate the needle seat into the needle seat conveying channel 210 in turn, and the needle seat will move in the needle seat conveying channel 210 in turn. When it moves to the tail end of the needle seat conveying channel 210, the needle seat CCD detection unit 220 will detect the needle seat to detect whether the conveyed needle seat is a good product. By detecting the needle seat in advance, the quality and pass rate of subsequent assembly are ensured. After the needle seat is detected, the needle seat PPU robot 230 will drive the needle seat clamp 240 to clamp the needle seat at the tail end of the needle seat conveying channel 210, and the needle seat clamp 240 will place the clamped needle seat into the fixture 120, thereby realizing automatic loading of the needle seat, thereby improving assembly efficiency.

The movable piece PPU manipulator 430 has a movable piece suction nozzle 440, and the bottom of the movable piece suction nozzle 440 is an inclined surface. The movable piece PPU manipulator 430 drives the movable piece suction nozzle 440 to suck the movable piece at the movable piece positioning unit 420 to the fixture 120.

[0053] Specifically, when loading the movable piece, the vibration plate vibrates the movable piece into the movable piece conveying channel 410, and the movable piece is conveyed in the movable piece conveying channel 410 in turn and conveyed to the movable piece positioning unit 420. After the movable piece is conveyed to the movable piece positioning unit 420, the movable piece positioning unit 420 will swing the movable piece at a set angle. After swinging into place, the movable piece PPU manipulator 430 will drive the movable piece suction nozzle 440 to suck the movable piece at the movable piece positioning unit 420, and place the sucked movable piece into the jig 120 so that it cooperates with the needle seat and the support rod, thereby realizing automatic loading of the movable piece. In order to facilitate the suction of the movable piece at the movable piece positioning unit 420, the bottom of the movable piece suction nozzle 440 in this embodiment is an inclined surface, which is coordinated with the swing angle of the movable piece positioning unit 420 through the inclined surface, so that the movable piece suction nozzle 440 is more convenient when sucking the movable piece, and the movable piece can be smoothly placed in the jig 120.

[0054] In order to achieve the swinging of the movable piece at a set angle and facilitate its absorption, the movable piece positioning unit 420 includes a positioning rotary cylinder 421 and a positioning fixture 422. The positioning fixture 422 is connected to the positioning rotary cylinder 421. A positioning groove 423 is provided on the positioning fixture 422.

In the initial state, the positioning groove 423 of the positioning fixture 422 is connected to the tail end of the movable piece feeding channel 410, and the movable piece in the movable piece feeding channel 410 will be transported to the positioning groove 423 in sequence. After being transported to the positioning groove 423, the positioning rotary cylinder 421 will rotate with the positioning fixture 422, so that the movable piece in the positioning groove 423 is rotated to the set angle, and then it can be sucked by the movable piece suction nozzle 440, so as to facilitate the absorption and feeding of the movable piece.

[0055] See also Fig. 9 and Fig.10 In order to automatically load the springs, the spring loading mechanism 500 in this embodiment includes a spring conveying channel 510, a spring positioning unit 520 and a spring PPU manipulator 530. The spring positioning unit 520 is arranged at the tail end of the spring conveying channel 510. The spring conveying channel 510 is used to convey the springs.

The spring PPU manipulator 530 drives the spring clamp 540 to clamp the spring at the spring positioning unit 520 to the fixture 120.

[0056] Similarly, the spring conveying channel 510 is connected to the vibration plate, and the vibration plate vibrates the spring into the spring conveying channel 510. The spring is then conveyed in the spring conveying channel 510 in sequence and conveyed to the spring positioning unit 520. The spring is clamped and positioned by the spring positioning unit 520. After the spring is clamped and positioned, the spring PPU manipulator 530 drives the spring clamp 540 to clamp the spring clamped and positioned by the spring positioning unit 520 again, and places the clamped spring into the fixture 120, so that the two ends of the spring cooperate with the support rod and the moving plate respectively, so as to realize automatic loading of the spring and improve the subsequent assembly efficiency.

When the movable plate lever 650 is inserted, the moving cylinder 620 drives the moving plate 640 to move to one side. While the moving plate 640 is moving, the movable plate lever 650 will move the movable plate to one side, and when the movable plate is moving, the pressing cylinder 630 will drive the movable plate pressure rod 660 to press the other end of the movable plate, so as to achieve forward shifting and pressing at the same time until the pressing end of the movable plate is stuck on the needle seat. At this time, the spring will tighten the movable plate and the support rod, so as to realize the automatic assembly between the support rod, the movable plate, the spring and the needle seat, thereby improving the assembly efficiency and quality and ensuring the qualified rate of assembly.

The dividing rotating cylinder 743 drives the dividing plate 744 to close the good product discharge port 741 or the defective product discharge port 742.

[0060] When the needle seat, support rod, movable plate and spring are assembled, the turntable 110 will rotate with the fixture 120 to the discharging mechanism 700. At this time, the PPU manipulator 710 will drive the discharging clamp 750 to clamp the assembled product in the fixture 120 and clamp it to the detection clamp 720. The detection clamp 720 will transfer and clamp the assembled product. After the detection clamp 720 clamps the assembled product, the discharging CCD detection unit 730 will detect the clamped assembled product to detect whether it is a good assembly product or a defective assembly product. When it is detected as a good assembly product, the material dividing rotating cylinder 743 It will drive the dividing plate 744 to rotate to the defective product outlet 742, and the dividing plate 744 will close the defective product outlet 742.
