Detailed Implementation

[0038] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0039] Reference Figures 1-2 A high-precision three-axis rotary automatic assembly equipment for master needles is disclosed. The equipment installs master needles 1 onto plastic shells 2. It includes a frame 3, an operating table 4 on the frame 3, a protective cover 5 on the operating table 4, a protective plate 6 on the protective cover 5, and an opening 7 on the protective plate 6. The area between the upper part of the operating table 4 and the inner wall of the protective cover 5 is the operating area 8. The operating area 8 integrates a transmission device 9, a pressing device 10, a vibrating feeder 11, and a feeding assembly device 12. The transmission device 9 is used to convey the plastic shell 2, the pressing device 10 is used to assemble the master needles 1 onto the plastic shell 2, the vibrating feeder 11 is used to transport the master needles 1, and the feeding assembly device 12 is used to feed the master needles 1 onto the plastic shell 2. The protective cover 5 integrates a touch screen 25, and the frame 3 is equipped with an electrical cabinet 27. The touch screen 25 is used to view the data and production information of the entire equipment.

[0040] Reference Figure 10 and Figure 11 An electrostatic fan 26 is installed on one side of the vibrating feeder 11;

[0041] Reference Figures 4-5 The transmission device 9 consists of an indexing cam mechanism 91 mounted on the operating table 4 and a turntable 92 located at the output end of the indexing cam mechanism 91. A fixture 13 is mounted on the turntable 92, which is used to place and support the plastic shell 2. An industrial camera 14 is used to detect the position of the plastic shell 2. The industrial camera 14 is mounted on the feeding assembly device 12. The height of the fixture 13 is lower than the height of the opening 7.

[0042] Specifically, multiple plastic shells 2 can be mounted on tooling 13 for conveying. The transmission device 9 can drive tooling 13 to rotate, rotating tooling 13 to the loading assembly device 12 for assembly. The vibrating feeder 11 can feed the female needle 1 to the loading assembly device 12. The vibrating feeder 11 is a circular vibrator and a rhomboid vibrator. The rhomboid vibrator is the conveying channel. The circular vibrator conveys the female needle 1 to the rhomboid vibrator. The rhomboid vibrator is used to convey the female needle 1. The loading assembly device 12 picks up the female needle 1 and inserts it into the insertion hole of the plastic shell 2. After the female needle 1 is assembled onto the plastic shell 2, the transmission device 9 continues to drive the tooling 13 to the pressing device 10. The pressing device 10 presses the female needle 1 into the plastic shell 2. With the help of the industrial camera 14, the position of the insertion hole on the plastic shell 2 can be monitored in real time, thereby ensuring the accurate feeding position of the female needle 1. The electrostatic fan 26 can prevent multiple female needles 1 from sticking together during the conveying process. The electrical cabinet 27 is equipped with a PLC controller (not shown in the figure) to control the automated operation of the equipment.

[0043] Reference Figure 3 and Figure 7 In this embodiment, the pressing device 10 includes a three-axis servo electric cylinder 101 and a pressing mechanism 102. The pressing mechanism 102 consists of a multiplier cylinder 1021 mounted on the three-axis servo electric cylinder 101, a pressing component 1022 mounted on the output end of the multiplier cylinder 1021, and a laser displacement sensor 1023 mounted on one side of the multiplier cylinder 1021.

[0044] Specifically, when the tooling 13 is transmitted to the pressing device 10 by the transmission device 9, the multiplier cylinder 1021 is activated to drive the pressing component 1022 to descend and press the female needle 1 into the insertion hole of the plastic shell 2. The laser displacement sensor 1023 detects the distance between itself and the upper surface of the pressing component 1022, and detects whether the female needle 1 has been pressed into place by detecting the displacement.

[0045] Reference Figures 8-9In this embodiment, the loading and assembly device 12 includes a three-axis servo electric cylinder 121 and a material handling mechanism 122. The material handling mechanism 122 consists of a support frame 1221, three sets of drive components 1222 mounted on the support frame 1221, and a pneumatic unit 1223. The drive components 1222 consist of a fixing member 12221 mounted on one side of the support frame 1221, a stepper motor 12222 mounted on one side of the support frame 1221, a drive wheel 12223 located at the output end of the stepper motor 12222, a driven wheel 12224 rotatably connected to one side of the support frame 1221, and a synchronous belt 12223 rotatably connected to the outer wall of the drive wheel 12223 and the driven wheel 12224. 225. A movable part 12226 fixed on the outer wall of the timing belt 12225, a rotating part 12227 rotatably connected to the inner wall of the movable part 12226, and a connecting part 12228 installed below the rotating part 12227 are all composed of an air inlet pipe 12231, a suction nozzle 12232 located below the air inlet pipe 12231, a stepper motor 12233 mounted on the fixed part 12221, a drive wheel 12234 located at the output end of the stepper motor 12233, and a timing belt 12235 rotatably connected to the drive wheel 12234 and the outer wall of the rotating part 12227. The connecting part 12228 is assembled with the suction nozzle 12232.

[0046] Specifically, the rotating part 12227, the connecting part 12228, and the suction nozzle 12232 are all movably connected to the outer wall of the air inlet pipe 12231, and can move up and down on the outer wall of the air inlet pipe 12231. The industrial camera 14 is mounted on the fixing part 12221. When the tooling 13 is conveyed to the loading assembly device 12 through the transmission device 9, the industrial camera 14 captures the image information of the plastic shell 2. According to the position of the insertion hole on the plastic shell 2, the female needle 1 is picked up and assembled onto the plastic shell 2. The movement adjustment method of the loading assembly device 12 and the pressing device 10 is the same, so it will not be described in detail. When the material handling mechanism 122 moves to the vibrating feeder 11 to pick up the female needle 1, there are three suction nozzles 12232. Each of the three suction nozzles 12232 is movably connected to one of the three air inlet pipes 12231. Thus, when it is necessary to pick up the female needle 1 from the vibrating feeder 11, the three-axis servo cylinder 121 moves the material handling mechanism 122 to the female needle 1, aligning the three suction nozzles 12232 with the position of the female needle 1. Simultaneously, multiple stepper motors 12222 are activated, driving the drive wheel 12223 to rotate. The rotation of the drive wheel 12223 is transmitted via a synchronous belt. 12225 drives the driven wheel 12224 to rotate, and the rotation of the driven wheel 12224 drives the moving part 12226 to move downward, so that the three suction nozzles 12232 are located a short distance above the mother needle 1. The air inlet pipe 12231 is connected to an external vacuum generator, and the external vacuum generator introduces compressed air into the air inlet pipe 12231. The compressed air flows at high speed through the narrow suction nozzle 12232 to achieve pressure conversion. The increased flow velocity at the suction nozzle 12232 leads to a decrease in static pressure, forming a negative pressure zone at the outlet, thereby sucking up the mother needle 1 and realizing the synchronous feeding of multiple mother needles 1. During the process of sucking up the mother needle 1 In the process, the stepper motor 12233 can be started to drive the rotating part 12227 to rotate through the drive wheel 12234 and the synchronous belt 12235. The rotation of the rotating part 12227 drives the suction nozzle 12232 to rotate through the connector 12228. The negative pressure detection is used to determine whether the mother needle 1 is in place. After suction is completed, the three-axis servo cylinder 121 moves multiple mother needles 1 to the plastic shell 2, breaks the negative pressure at the suction nozzle 12232, and releases the mother needles 1. The above operation is repeated to complete the picking and feeding of mother needles 1. Three mother needles 1 can be picked up and fed at one time, which greatly improves the assembly efficiency of mother needles 1.

[0047] Reference Figure 4 In this embodiment, a support platform 15 is mounted on one side of the operating table 4. A second cylinder 16 is mounted on the support platform 15. A movable wedge 17 is fixedly mounted on the output end of the second cylinder 16. A guide member 18 is fixedly mounted on the support platform 15. The movable wedge 17 is slidably connected to the outer wall of the guide member 18. A fixed wedge 19 is provided above the movable wedge 17. A support plate 20 is fixedly mounted above the fixed wedge 19. The support plate 20 abuts against the bottom of the turntable 92. A hard limit 21 is provided on the side of the upper surface of the support platform 15 away from the second cylinder 16.

[0048] Specifically, cylinder 16 pushes the movable wedge 17 to move towards the side of the hard limit 21. The movable wedge 17 moves on the guide 18 and abuts against the fixed wedge 19. One side of the movable wedge 17 abuts against the hard limit 21. The movable wedge 17 and the fixed wedge 19 support the turntable 92, achieving stable support for the turntable 92. This structure is a wedge mechanism, and its force formula is existing technology, so it will not be explained in detail. This improves the support stability of the turntable 92. The movable wedge 17 can automatically lock after being subjected to vertical force, without the need for continuous external force.

[0049] Reference Figures 12-13 In this embodiment, a tooling identification sensor group 22 is mounted on one side of the upper part of the operating table 4. The tooling identification sensor group 22 is used to detect the model of the tooling 13.

[0050] Reference Figure 1 In this embodiment, the outer periphery of the protective cover 5 is rotatably connected to six openable and closable protective doors 23 via hinges.

[0051] Specifically, when the equipment inside the operating area 8 malfunctions, the corresponding openable protective door 23 can be opened to enable rapid repair, and the mother needle 1 can be placed inside the vibrating feeder 11, thereby effectively improving the practicality and convenience of the device.

[0052] Reference Figure 6 In this embodiment, an air source processing system 24 is installed below the operating console 4.

[0053] Specifically, the gas source processing system 24 is responsible for providing the required gas source to the numerous devices within the operating area 8.

[0054] Working principle: When it is necessary to assemble the female needle 1 onto the plastic shell 2, firstly, multiple plastic shells 2 are placed onto the assembly fixture 13. The indexing cam mechanism 91 drives the turntable 92 to rotate. The rotation of the turntable 92 drives the fixture 13 to be conveyed. The turntable 92 rotates at a specified angle to convey the fixture 13 to the feeding assembly device 12 for female needle 1 assembly. The feeding assembly device 12 picks up multiple female needles 1 from the vibrating feeder 11 and moves the female needles 1 above the plastic shell 2 through the three-axis servo electric cylinder 121. The drive component 1222 feeds multiple female needles 1 into the insertion holes of the plastic shell 2. The specific assembly method is: row assembly, that is, the female needles 1 are assembled onto the plastic shell 2 one by one in the horizontal direction. The three suction nozzles 12232 are all independent. The assembly process for vertical operation is as follows: One stepper motor (12222) is started, driving the corresponding drive wheel (12223) to rotate. The rotation of drive wheel (12223) drives driven wheel (12224) to rotate via synchronous belt (12225). The rotation of driven wheel (12224) drives moving component (12226) downwards. The downward movement of moving component (12226) drives rotating component (12227) downwards. The downward movement of rotating component (12227) drives suction nozzle (12232) downwards via connecting component (12228). Rotating component (12227), connecting component (12228), and suction nozzle (12232) all move downwards along the outer wall of air intake pipe (12231), while air intake pipe (12231) remains stationary. Simultaneously, rotating component... When 12227 moves downward, it will cause the synchronous belt 12235 to change position, but it will not affect the use of the synchronous belt 12235. One suction nozzle 12232 descends, causing the female needle 1 to insert into the first socket on the plastic shell 2. The three-axis servo cylinder 121 is activated again to drive the material handling mechanism 122 to translate, so that the second suction nozzle 12232 is aligned with the second socket on the plastic shell 2, and the second female needle 1 is inserted into the second socket on the plastic shell 2. The three-axis servo cylinder 121 is activated again to drive the material handling mechanism 122 to translate, so that the third suction nozzle 12232 is aligned with the third socket on the plastic shell 2, and the third female needle 1 is inserted into the third socket on the plastic shell 2 through the suction nozzle 12232. By analogy, all the female needles 1 are fed onto the plastic shell 2, and the tooling 13 is conveyed to the pressing device 10. The pressing device 10 adjusts the pressing component 1022 above the female needle 1 through the three-axis servo electric cylinder 101, and drives the pressing component 1022 to descend through the force-multiplying cylinder 1021 to press the female needle 1 into the insertion hole of the plastic shell 2. The laser displacement sensor 1023 detects whether the pressing is in place, thereby realizing the assembly of the female needle 1 onto the plastic shell 2. The automatic assembly of the female needle 1 is realized through the transmission device 9, the feeding assembly device 12 and the pressing device 10, and multiple female needles 1 can be fed onto the plastic shell 2 at one time. Compared with the existing technology, the assembly efficiency of the female needle 1 is greatly improved, and the practicality and convenience of the device are enhanced.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
