[0037] Referring to Figure 5 , Figure 5This is a structural diagram of the automatic needle feeding machine 7. A pneumatic feeding device 13 is installed on one side of the automatic needle feeding machine 7. The pneumatic feeding device 13 includes a second cylinder 131 installed on one side of the automatic needle feeding machine 7, a rotary cylinder 132 equidistantly mounted on the second cylinder 131, and a suction pipe 133 rotatably connected to the output end of the rotary cylinder 132. The automatic needle feeding machine 7 feeds needles 20, and the feeding of subsequent needles 20 pushes the movement of the preceding needles 20. An electrostatic fan is also installed on one side of the automatic needle feeding machine 7 to prevent multiple needles 20 from sticking together during the feeding process. The suction pipe 133 is connected to an external vacuum system, which attracts the needles 20 into the suction pipe 133. There are four sets of rotary cylinders 132. After the first and third rotary cylinders 132 adsorb the female needles 20 through their corresponding two suction pipes 133, cylinder 2 131 is activated to drive the four sets of rotary cylinders 132 to move horizontally, so that the suction pipes 133 corresponding to the second and fourth rotary cylinders 132 are aligned with the discharge channel of the automatic female needle feeder 7, and the female needles 20 are fed. Four female needles 20 can be fed at one time. After the gripping part 61 of the four-axis robotic arm 6 grips the female needles 20, it drives the rotary cylinders 132 to return to their original positions. The angle adjustment method of the rotary cylinders 132 is as follows: an adjustable hard limit buffer is set below it.

When it is 85 degrees, it can be slowly rotated to 90 degrees to realize the angle adjustment of the rotary cylinders 132. Its rotation angle is 0 degrees at the origin position and 90 degrees in the vertical state.

[0038] See Figures 6-8 , Figure 6 This is a structural diagram of the four-axis robotic arm 6. Figure 7 Here are detailed structural diagrams of the four-axis robotic arm 6. Figure 8This is a structural diagram of the gripping part 61 of the four-axis robotic arm 6. The gripping part 61 is located on the lower side of one side of the four-axis robotic arm 6. A pressing part 62 is provided on the gripping part 61. An industrial camera 23 is mounted on the four-axis robotic arm 6. The industrial camera 23 is used to acquire image information of the plastic shell 15. The gripping part 61 includes a housing 611 and electric grippers 612 symmetrically installed inside the housing 611. The electric grippers 612 are used to grip the female needle 20. The pressing part 62 includes a cylinder 621 installed on the upper surface of the housing 611, a floating joint 622 provided on the cylinder 621, an optical axis 623 connected to the floating joint 622, a pressing head 624 installed below the optical axis 623, and a linear bearing 625 located inside the housing 611. Bearing 625 guides the pressure head 624. A laser displacement sensor 24 is installed on the housing 611. A clearance groove 25 is provided on the side of the housing 611 near the laser displacement sensor 24 to allow the laser displacement sensor 24 to pass. A moving part 26 is installed on the pressure head 624. The moving part 26 rises and falls synchronously with the pressure head 624 and can move up and down inside the clearance groove 25. Industrial camera 23 captures image information of the plastic shell 15. The movement trajectory of the four-axis robotic arm 6 is adjusted by the cooperation of industrial camera 23 and controller 22, so that the gripping part 61 of the four-axis robotic arm 6 is precisely moved to the position of the female needle 20 and the female needle 20 is gripped by two sets of electric grippers 612. Continue reading Figure 8 The two sets of electric grippers 612 have a total of four gripping positions. The spacing between the four gripping positions corresponds one-to-one with the spacing between the four suction pipes 133, so that the four gripping positions can grip the four female needles 20 in the four suction pipes 133, realizing the gripping of four female needles 20 at one time, improving the material handling efficiency. The electric grippers 612 are provided with semi-circular grooves that fit the outer wall of the female needles 20, so that the female needles 20 can be gripped in the semi-circular grooves. After the material handling is completed, the four-axis robotic arm 6 moves above the fixture 5 and places the female needles 20 into the plastic shell 15 on the fixture 5. Continue to refer to Figure 7 Industrial camera 23 captures image information of plastic shell 15 and transmits it to PLC controller (not shown in the figure) installed in cabinet 1. PLC controller controls the movement trajectory of four-axis robotic arm 6 through controller 22, aligning the female pins 20 with the assembly holes on plastic shell 15. After alignment, it controls the electric gripper 612 of four-axis robotic arm 6 to release the gripper, assembling four female pins 20 at once, corresponding to the first assembly hole on each of the four plastic shells 15. The female pins 20 fall on the inner wall of the assembly hole on the plastic shell 15. Then, cylinder 621 is activated, driving the pressure head 624 to move downward. A linear bearing 625 is also installed in the housing 611 to support and guide the movement of the pressure head 624, thus playing a guiding role. See further... Figure 8The bottom of the pressure head 624 is flat, so that the pressure head 624 can move downward to abut against the female needle 20 and press the female needle 20 into the assembly hole on the plastic shell 15, pressing it into place.

[0039] See Figure 9 , Figure 9 The top view shows that the controller 22 is installed inside the protective frame 2. The four-axis robotic arm 6 is connected to the controller 22 in communication. The controller 22 is located on one side of the four-axis robotic arm 6. The controller 22 is used to control the movement of the four-axis robotic arm 6. The industrial camera 23 captures the movement trajectory of the four-axis robotic arm 6.

[0040] See Figure 10 The transmission assembly 4 includes a drive motor 41 mounted on the cabinet 1 and a turntable 42 mounted on the output end of the drive motor 41. A partition plate 21 is fixedly provided in the middle of the upper surface of the turntable 42. The transmission assembly 4 is used to convey the tooling 5, that is, to convey the multiple plastic shells 15 mounted on the tooling 5. The drive motor 41 has a fixed rotation angle, rotating 180 degrees each time. When the drive motor 41 is started, it rotates in one direction only, that is, it can only rotate in one direction. The drive motor 41 drives the turntable 42 to rotate. Two [unclear text - possibly referring to two different types of equipment] are mounted on the turntable 42. Tooling 5, turntable 42 rotates 180 degrees, driving one of tooling 5 to rotate to the four-axis robotic arm 6 for assembly of the female needle 20. After assembly, turntable 42 rotates 180 degrees in the same direction to return to its original position, and the other tooling 5 rotates to the four-axis robotic arm 6 for assembly. While the four-axis robotic arm 6 is assembling the female needle 20 on the other tooling 5, the worker can remove the assembled plastic shell 15 from tooling 5, which effectively improves assembly and unloading efficiency. A wedge mechanism is also provided on one side of the transmission component 4 to support the rotational stability of turntable 42.

[0041] See Figure 3 , Figure 4 and Figure 11 , Figure 11This is a diagram showing the assembled state of the female needle 20 and the plastic shell 15. The fixture 5 has equidistantly spaced placement slots 14, in which the plastic shell 15 is placed. A slide rail 16 is fixed to the fixture 5, and a limit frame 17 is slidably connected to the slide rail 16. A magnetic component 18 is inserted into the limit frame 17. One side of the slide rail 16 is a magnetic surface 19. The limit frame 17 is limited on the slide rail 16 by the magnetic component 18 and the magnetic surface 19. When it is necessary to assemble and limit the plastic shell 15 onto the fixture 5, the magnetic component 18 is removed from the limit frame. Remove the plastic shell 17 from the limiting frame 17, place multiple plastic shells 15 in the placement slot 14, push the limiting frame 17 to move it on the slide rail 16 and make one side of it abut against the plastic shell 15, insert the magnetic suction component 18 into the limiting frame 17. Since the magnetic suction component 18 corresponds to the magnetic suction surface 19, the magnetic suction component 18 is attracted to the magnetic suction surface 19, thereby limiting the limiting frame 17 on the slide rail 16, realizing the stable assembly of the plastic shell 15 on the tooling 5. It is convenient to use and facilitates the loading and unloading of the plastic shell 15.

[0042] Continue reading Figure 1 A touch screen 27 is installed on one side of the protective frame 2. The touch screen 27 can display the equipment's operating information and processing information in real time, which is convenient to use. A power socket is also provided on the back of the cabinet 1, which can be connected to an external power source to supply power to the device and ensure its operation.

[0043] Working principle: The equipment is equipped with casters and support legs at the bottom. The casters allow the equipment to be moved to a suitable position. The female needle 20 is assembled onto the plastic shell 15. Multiple plastic shells 15 are assembled onto the tooling 5. The tooling 5 is then assembled onto the transmission assembly 4 via positioning pin 10, positioning pin 21, pin hole 18, pin hole 29, and handle 12. Two tooling 5s can be assembled onto the transmission assembly 4. The drive motor 41 is started, which drives the turntable 42 to rotate. 2. The four-axis robotic arm 6 rotates to wait for the assembly of the female needles 20. The female needles 20 are fed by the automatic female needle feeder 7 and the rotary cylinder 132. The rotary cylinder 132 makes the four female needles 20 vertical. The four-axis robotic arm 6 can grip the vertically positioned female needles 20. There are two sets of electric grippers 612 with four gripping positions, so four female needles 20 can be gripped at a time, which effectively improves the feeding efficiency. After gripping, the four-axis robotic arm 6 moves to the plastic shell 15 and aligns the female needles 20 with the plastic shell 15. The assembly holes are aligned, and the electric gripper 612 is released to allow the female needle 20 to fall into the assembly hole on the plastic shell 15. The pressing head 624 is driven by the pressing part 62 to move downward and press the female needle 20 into the plastic shell 15. During the downward movement of the pressing head 624, the moving part 26 moves downward along the inner wall of the clearance groove 25. During the movement, the laser displacement sensor 24 detects the distance between itself and the upper surface of the moving part 26 in real time. The distance detection is used to determine whether the female needle 20 has been pressed into place, thus completing the assembly. After the assembly is completed, the drive motor 41 is restarted to drive the turntable 42 to rotate and return to its position. The operator removes the assembled plastic shell 15 from the tooling 5. The two-station assembly method realizes the continuous assembly of the female needle 20, which effectively improves the efficiency of the female needle 20 assembly. Furthermore, the assembly and pressing processes of the female needle 20 are integrated, thereby reducing the floor space, improving space utilization, and thus enhancing the practicality and convenience of the equipment.
