Example

[0034] A connector terminal automated assembly device includes a frame 1 and also includes: a terminal mounting assembly arrayed above the frame 1, the terminal mounting assembly and the positioning holes for mounting terminals in the connector body are matched and arranged in the horizontal direction, the terminal mounting assembly includes an assembly table 2 and a first cylinder 4 fixedly mounted on the upper surface of the assembly table 2, the air outlet end of the first cylinder 4 is connected to a positioning groove 23 through an air pipe 29, a boosting valve 24 is provided in the air pipe 29, an extension plate 22 is slidably provided in the positioning groove 23, and a second conveying groove 28 is provided in the extension plate 22 and passes through the positioning groove 23.

[0035] In this embodiment, a terminal installation assembly is provided on one side of the upper surface of the frame 1, including an assembly table 2 and a first cylinder 4 provided on the upper surface of the assembly table 2. The first cylinder 4 is used to inject airflow into the positioning groove 23, and then the terminal is installed into the connector body through the extension plate 22 sliding in the positioning groove 23. Compared with manual assembly, it has high stability and efficiency, and can effectively reduce the defective rate of the connector.

[0036] It should be noted that after starting the first cylinder 4, when the air flow in the first cylinder 4 passes through the air pipe 29, the boost valve 24 is started to increase the air flow pressure, further increasing the speed and force of the terminal entering the connector, ensuring a tight fit after the terminal is assembled.

[0037] The terminal installation assembly also includes a vibrating loading tray 3, and a third cylinder 27 is provided on one side of the discharge port of the vibrating loading tray 3. A feed plate 26 is fixedly installed on the output shaft end of the third cylinder 27, and limiting plates 25 are symmetrically provided on both sides of the feed plate 26. The terminal is pushed into the positioning groove 23 through the feed plate 26.

[0038] In this embodiment, a vibrating loading tray 3 is provided on one side of the positioning groove 23. When the vibrating loading tray 3 is started, the bulk terminals are transported in an orderly manner. The terminals are transported to one side of the positioning groove 23. The third cylinder 27 is started to push the terminals into the positioning groove 23 through the feeding plate 26. The number of terminal limiting grooves in the positioning groove 23 and the number of terminal mounting ports in the connector are matched.

[0039] It should be noted that a counter is provided outside the positioning groove 23 at the terminal entrance. When the number of terminals in the positioning groove 23 reaches the upper limit, the vibration loading tray 3 and the third cylinder 27 stop working, and the above-mentioned first cylinder 4 is started to load the entire row of terminals in the positioning groove 23 into the connector through air pressure.

[0040] It should be noted that, when the feeding plate 26 pushes the terminals, the limiting plates 25 provided on both sides of the feeding plate 26 can guide the terminals and ensure that the terminals enter the positioning grooves 23 in an orderly manner.

[0041] A conveying assembly for conveying the connector body includes a track 5 and a conveyor belt 7 that is arranged on one side of the track 5 for transmission. The terminal is slidably arranged in the track 5. One end of the conveyor belt 7 is connected to a motor 6 for transmission, and a shift plate for pushing the terminal to move is arranged on one side of the conveyor belt 7. A material guide plate 21 is provided at the terminal output end of the track 5.

[0042] In this embodiment, a track 5 is provided and a conveyor belt 7 is provided inside the track 5. By starting the motor 6, the belt plate on one side of the conveyor belt 7 can be driven to transmit inside the track 5. The portion of the surface of the conveyor belt 7 located inside the track 5 is connected to a shift plate. The connector body is placed inside the track 5, and the connector body is driven by the conveyor belt 7 to be transported to one side along the track 5. After reaching the position of the relative positioning groove 23, the terminal is installed into the connector body.

[0043] Specifically, the track 5 is set to a hollow structure, and a cavity 15 is opened in the track 5. An air hole 16 is opened on the side of the track 5 close to the extension plate 22. The air hole 16 and the cavity 15 are set through each other, and a first conveying groove 13 for placing terminals is opened on one side of the track 5.

[0044] In this embodiment, a first conveying groove 13 is opened in the track 5, and the connector body is placed in the first conveying groove 13. During the transmission process of the conveyor belt 7, the shift plate will be brought to move the connector body to the assembly station.

[0045] It should be noted that the track 5 is set to a hollow structure, and a ventilation hole 16 is opened on one side of the cavity 15. The air in the cavity 15 is discharged outward through the air hole 16 by utilizing the traction of the conveyor belt 7 to blow dust off the terminals before assembly and the surface of the mechanical structure through which the terminals pass during transportation.

[0046] A positioning assembly is arranged above the conveying assembly, and the positioning assembly is used to position the connector body at the moment of terminal installation. The positioning assembly includes a second cylinder 8, a frame 10 is fixedly installed on one side of the upper surface of the frame 1, and the second cylinder 8 is fixedly connected to one side of the frame 10 through a bracket 9. The output shaft end of the second cylinder 8 is fixedly connected to a pressure rod 12, and the pressure rod 12 is slidably connected to the top of the track 5. A guide hole 14 is opened at the top of the track 5 at the sliding connection position of the pressure rod 12, and a spring 11 is connected between the second cylinder 8 and the track 5 and on the outer wall of the pressure rod 12.

[0047] In this embodiment, since the connector body moves in the first conveying groove 13, there is a clearance fit between the track 5 and the first conveying groove 13. In order to ensure that the connector body can maintain a stable combination when the terminal is assembled, a positioning assembly is provided above the connector body. When in use, after the connector body moves to the assembly position, the second cylinder 8 is started to drive the pressure rod 12 downward, and the sliding connection between the pressure rod 12 and the guide hole 14 is used to keep the force of the pressure rod 12 stable, and the connector body is pressed at the moment the terminal is inserted into the connector body.

[0048] It should be noted that in order to avoid excessive impact force when the second cylinder 8 presses down on the connector body, which may cause damage to the connector body, a spring 11 is provided between the pressure rod 12 and the track 5 to generate a certain buffer during the downward movement of the pressure rod 12, thereby providing protection for the connector body.

[0049] A blowing drive assembly is provided in the cavity 15 below the track 5, and the blowing drive assembly includes a rack 18 and a first gear 19 engaged with one side of the rack 18. The first gear 19 is rotatably installed in the cavity 15 through a rotating shaft 20. A slide groove 17 is provided on one side of the track 5, and the rack 18 is slidably connected to the slide groove 17. A second gear 30 is engaged with one side of the first gear 19, and a support shaft 32 is fixedly connected to the second gear 30, and a blade 31 is fixedly installed on the surface of the support shaft 32.

[0050] In this embodiment, a blowing drive assembly is provided in the cavity 15 near the bottom of the track 5, specifically including a first gear 19 and a rotating shaft 20. A slide groove 17 is opened on the side wall of the cavity 15 of the track 5, and a rack 18 is slidably connected in the slide groove 17. The rack 18 is connected to the conveyor belt 7. The conveyor belt 7 can drive the rack 18 to move during the transmission process, which can drive the first gear 19 to rotate, and finally drive the second gear 30 to rotate, thereby driving the blades 31 on the surface of the support shaft 32 to rotate, generating air flow, which is blown out through the air hole 16 to the surface of the mechanical structure passed by the terminal during transportation and the surface of the emitted terminal, for dust blowing treatment to ensure the assembly quality of the connector.

[0051] Specifically, a traction assembly is provided on the outer side of the conveyor belt 7 on the track 5. The traction assembly includes a connecting plate 33 and a connecting rod 35 connected between the connecting plate 33 and the rack 18. The connecting plate 33 is fixedly installed on one side of the conveyor belt 7. A positioning sleeve 36 is connected to one side of the rack 18. One end of the connecting sleeve 34 is fixedly connected to the surface of the positioning sleeve 36. A connecting sleeve 34 is fixedly installed on the surface of the connecting plate 33. One end of the connecting rod 35 is inserted into the connecting sleeve 34. A positioning column 37 is connected to one side of the rack 18. The positioning column 37 and the positioning sleeve 36 are fixedly connected.

[0052] In this embodiment, the traction assembly for connecting the conveyor belt 7 and the rack 18 includes a connecting plate 33 and a connecting rod 35. The connecting plate 33 is fixedly installed on the outside of the conveyor belt 7. A connecting sleeve 34 is connected to one side of the connecting plate 33. A positioning column 37 is connected to one side of the rack 18. A positioning sleeve 36 is sleeved on the outer wall of the positioning column 37. The outer wall of the positioning sleeve 36 is fixedly connected to the connecting rod 35. One end of the connecting rod 35 is connected to the connecting sleeve 34. Therefore, during the transmission of the conveyor belt 7, it can stably drive the rack 18 to move in the slide groove 17, thereby driving the blades 31 on the surface of the above-mentioned support shaft 32 to rotate, driving the air flow to form wind for dust blowing.

[0053] It should be noted that the conveyor belt 7 provided in this embodiment is connected to a shift plate on one side and a traction assembly on the other side. During the assembly process, an alternating forward and reverse transmission method is adopted. The initial arrangement of the traction assembly installed on one side of the conveyor belt 7 is set at one end of the track 5 close to the guide plate 21. After each batch of connectors is assembled, the rack 18 follows the conveyor belt 7 for a stroke approximately equal to the total length of the track 5. When all the connector bodies in the track 5 are assembled, the side of the conveyor belt 7 with the traction assembly installed can be reset.

[0054] In the present invention, a terminal installation assembly is provided on one side of the upper surface of the frame 1, including an assembly table 2 and a first cylinder 4 provided on the upper surface of the assembly table 2. When the first cylinder 4 is activated, air is pumped into the positioning groove 23, and then the terminal is installed into the connector body through the extension plate 22 sliding in the positioning groove 23. Compared with manual assembly, the stability and efficiency are high, and the defective rate of the connector can be effectively reduced.

[0055] Start the vibration loading tray 3 to transport the bulk terminals in an orderly manner, and transport the terminals to one side of the positioning groove 23. Start the third cylinder 27 to push the terminals into the positioning groove 23 through the feeding plate 26. The distance between each group of positioning grooves 23 and the upper surface of the frame 1 is different. The height and number of the positioning grooves 23 are matched with the position and number of the terminal installation ports in the connector. When the number of terminals in the positioning grooves 23 reaches the upper limit, the vibration loading tray 3 and the third cylinder 27 stop working, and start the first cylinder 4 to load the entire row of terminals in the positioning grooves 23 into the connector. The airflow pushes the extension plate 22 to extend from the positioning groove 23 to fit the connector body. A second conveying groove 28 connected to the positioning groove 23 is also provided in the extension plate 22. Therefore, the terminals finally enter the connector body through the positioning groove 23 and the second conveying groove 28 to complete the installation;

[0056] In order to ensure that the connector body can maintain a stable combination when the terminal is assembled, a positioning component is provided above the connector body. When in use, when the connector body is moved to the assembly position, the second cylinder 8 is activated to drive the pressure rod 12 downward. The sliding connection between the pressure rod 12 and the guide hole 14 maintains the force of the pressure rod 12 stable. When the terminal is installed in the connector body, the connector body is instantly pressed to ensure the terminal assembly accuracy.

[0057] A blowing drive assembly is provided in the cavity 15 near the bottom of the track 5, specifically including two groups of first gears 19 and a rotating shaft 20. A slide groove 17 is opened on the side wall of the cavity 15 of the track 5. A rack 18 is slidably connected in the slide groove 17 to connect the rack 18 and the conveyor belt 7. The conveyor belt 7 can drive the rack 18 to move during the transmission process, thereby driving the first gear 19 to rotate, and finally driving the second gear 30 to rotate, thereby driving the blades 31 on the surface of the support shaft 32 to rotate, generating air flow, which is blown out through the air hole 16 to the surface of the mechanical structure passed by the terminal during transportation and the surface of the emitted terminal, for dust blowing treatment to ensure the assembly quality of the connector.
