Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a connector pin assembly device. Background Technology

[0002] Connectors (also commonly known as circuit connectors or electrical connectors) are conductive devices that connect electrical circuits, consisting of a housing and pins. They are widely used in various electrical circuits to connect or disconnect circuits. This connection can be temporary and easily plugged in and out, or it can be a permanent connection between electrical devices or wires. For example, automotive connectors are electronic components in automotive electronic systems used to bridge circuit breaks or isolated circuits, allowing current to flow to achieve a predetermined function. They consist of contacts, a housing, an insulator, and accessories, and are widely used in various automotive subsystems. When processing connectors, a pin insertion process is required, where pins are inserted into the housing. A robotic arm is used to move the housing to a carrier, and after the pins are inserted by a pin insertion machine, the robotic arm performs the unloading process. However, while the pin insertion process is in progress, the next group must wait for all the processes of the first group to be completed before it can begin, reducing production efficiency.

[0003] For example, a connector pin assembly device described in patent CN221428208U includes a feeding box with a feeding cavity for collecting assembled connectors; a mounting plate mounted on the feeding box; and a pin assembly, a clamping assembly, a driving assembly, and a pushing assembly. The pushing assembly pushes the mounting shell into the clamping assembly, which then clamps and fixes it. The driving assembly then moves the clamping assembly, causing it to move the mounting shell into the pin assembly on the mounting plate. The pin assembly performs a pin insertion operation on the mounting shell. After the pin insertion operation is completed, the driving assembly continues to move the clamping assembly until it reaches the first connection port. At this point, the clamping assembly releases its grip on the mounting shell, allowing the mounting shell to fall into the feeding box, thus completing one pin insertion operation. However, during this process, preparation for the next pin insertion operation cannot be performed; the clamping assembly must return to its original position before the next pin insertion operation can be performed, reducing the device's production efficiency.

[0004] Based on this, a connector pin assembly device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-5 As shown, a connector pin assembly device includes a feeding box 1, a support plate 11 fixedly connected to the side wall of the feeding box 1, a feeding assembly 2 provided at the top of the support plate 11, an mounting plate 12 fixedly connected to the top of the feeding box 1, a feeding port communicating with the feeding box 1 on the mounting plate 12, a liftable receiving platform provided at the top of the mounting plate 12, a first connecting plate 13 and a second connecting plate 14 symmetrically arranged at the top of the mounting plate 12, a picking assembly 3 provided on the side wall of the first connecting plate 13, a feeding assembly 4 provided on the side wall of the second connecting plate 14, and a pin assembly (not shown in the figure) provided at the top of the mounting plate 12 away from the feeding assembly 4. The pin assembly includes an XYZ three-axis motion platform (not shown) driven by a servo electric cylinder, and its end is equipped with an electromagnetic crimp connector. The feeding assembly 2 includes a fixed plate 21, the bottom end of which is fixedly connected to the top end of the support plate 11. A stepper motor 22 is fixedly connected inside the fixed plate 21. A turntable 23 is fixedly connected to the output end of the stepper motor 22. A fixed frame 24 is evenly fixedly connected to the top end of the turntable 23. The picking component 3 includes a second motor 31, which is fixedly connected to the side wall of the first connecting plate 13. The output end of the second motor 31 is fixedly connected to a lead screw 32. One end of the lead screw 32 is rotatably connected to a protrusion on the side wall of the first connecting plate 13. The outer wall of the lead screw 32 is threadedly connected to a mounting bracket 33. Pneumatic suction cups 35 are symmetrically arranged on the mounting bracket 33 above the mounting plate 12. The feeding assembly 4 includes a second cylinder 41, which is fixedly connected to the side wall of the second connecting plate 14. The output end of the second cylinder 41 is fixedly connected to a first slider 42, which is slidably connected to a groove on the second connecting plate 14.

[0023] In this embodiment, the connector can be continuously conveyed by the feeding component 2 to the lifting plate 19. Then, the picking component 3 picks up the connector on the lifting plate 19 and conveys it to the pin assembly. After the pin insertion operation is completed, the unloading component 4 picks up the connector that has completed the pin insertion operation and conveys it into the unloading box 1.

[0024] In an optional embodiment, such as Figure 4 As shown, a first motor 15 is fixedly connected to the side wall of the first connecting plate 13. The output end of the first motor 15 passes through the first connecting plate 13 and is rotatably connected to the side wall of the second connecting plate 14. A first mechanical gripper 16 is symmetrically fixedly connected to the output end of the first motor 15. The PLC starts the first mechanical gripper 16 to clamp the connector on the lifting plate 19. After the clamping action is completed, the first motor 15 drives the first mechanical gripper 16 to rotate 180°, thereby placing the connector on the liftable receiving platform set on the mounting plate 12.

[0025] In an optional embodiment, such as Figure 4 As shown, a baffle 17 is symmetrically fixedly connected to the top of the mounting plate 12 near the fixed plate 21, and a first cylinder 18 is symmetrically fixedly connected to the bottom of the mounting plate 12. The output end of the first cylinder 18 passes through the mounting plate 12 and is fixedly connected to a lifting plate 19. The lifting plate 19 is inserted into the slot opened on the mounting plate 12. The connector is pushed onto the lifting plate 19 by the feeding assembly 2. Then, the first cylinder 18 is started by the PLC to drive the lifting plate 19 to move upward. The lifting plate 19 drives the connector to rise vertically synchronously into the recognition range of the industrial CCD vision sensor.

[0026] In an optional embodiment, such as Figure 3 As shown, electric push rods 25 are uniformly fixedly connected to the top of the turntable 23. A push plate 26 is fixedly connected to the output end of the electric push rod 25. The push plate 26 is slidably connected to the inner wall of the fixed frame 24. The stepper motor 22 is controlled by the PLC to rotate, which drives the turntable 23 to rotate synchronously, so that the turntable 23 drives the fixed frame 24 to rotate, so that the fixed frame 24 with the connector is docked with the mounting plate 12. Then the electric push rod 25 is started to push the push plate 26. The push plate 26 pushes the connector, so that it enters the mounting plate 12 and makes one side contact the baffle 17.

[0027] In an optional embodiment, such as Figure 4As shown, guide blocks 34 are symmetrically fixedly connected to the side wall of the mounting bracket 33. The guide blocks 34 are slidably connected to the groove opened on the first connecting plate 13. An industrial CCD vision sensor is provided on the side wall of the mounting bracket 33 near the pneumatic suction cup 35. The second motor 31 drives the lead screw 32 to rotate, causing the mounting bracket 33 to move axially and drive the pneumatic suction cup 35 to move above the connector. The industrial CCD vision sensor at the bottom of the mounting bracket 33 captures the position of the connector in real time. When the pneumatic suction cup 35 is in a suitable position, the lifting platform can be raised to move the connector upward, so that the pneumatic suction cup 35 can pick up and fix the connector. Then the pneumatic suction cup 35 transports the connector to the pin assembly, where the pin assembly performs the pin insertion operation on the connector.

[0028] In an optional embodiment, such as Figure 5 As shown, a third motor 43 is fixedly connected to the side wall of the first slider 42. The output end of the third motor 43 passes through the first slider 42 and is fixedly connected to a second slider 45. The second slider 45 is slidably connected to a groove opened on the first connecting plate 13. The output end of the third motor 43 passes through the outer wall of the first slider 42 and the second connecting plate 14. A second mechanical gripper 44 is symmetrically fixedly connected to the outer wall of the output end of the third motor 43. The PLC controls the second cylinder 41 to drive the first slider 42, so that the first slider 42 drives the third motor 43 and the second mechanical gripper 44 to move synchronously, so that the second mechanical gripper 44 approaches the connector located on the pin assembly. When the position is appropriate, the second mechanical gripper 44 picks up the connector and drives it to return to its original position by the second cylinder 41. Then the third motor 43 drives the second mechanical gripper 44 to rotate, so that the second mechanical gripper 44 rotates 180°, so that the connector is located above the feeding port. Then the clamping state of the second mechanical gripper 44 is canceled, so that the connector falls into the feeding box 1.

[0029] In an optional embodiment, such as Figure 2 As shown, the first motor 15, the first cylinder 18, the stepper motor 22, the electric push rod 25, the second motor 31, the pneumatic suction cup 35, the second cylinder 41, and the third motor 43 are electrically connected through a PLC control module. The PLC controls each component so that each component can accurately execute the pre-set program and avoid excessive deviation.

[0030] The above embodiment discloses a connector pin assembly device. During the pin insertion operation, the connectors to be processed are placed into the fixed frame 24. Then, the PLC controls the stepper motor 22 to rotate, driving the turntable 23 to rotate synchronously. The turntable 23 drives the fixed frame 24 to rotate, allowing the fixed frame 24 containing the connectors to align with the mounting plate 12. Subsequently, the electric push rod 25 is activated, pushing the push plate 26. The push plate 26 pushes the connector, allowing it to enter the mounting plate 12 and contact one side with the baffle 17. The push plate 26 is then reset. The PLC activates the first cylinder 18, driving the lifting plate 19 to move upwards. The lifting plate 19 moves the connector upwards synchronously a certain distance. Then, the PLC activates the first mechanical gripper 16 to lift the connector... The connector is clamped on plate 19. After the clamping action is completed, the first motor 15 drives the first mechanical gripper 16 to rotate 180°, thereby placing the connector onto the liftable receiving platform set on the mounting plate 12. Then, the second motor 31 drives the lead screw 32 to rotate, causing the mounting bracket 33 to move axially, driving the pneumatic suction cup 35 to move above the connector. The industrial CCD vision sensor set at the bottom of the mounting bracket 33 captures the position of the connector in real time. When the pneumatic suction cup 35 is in a suitable position, the liftable receiving platform moves the connector upward, making it convenient for the pneumatic suction cup 35 to pick up and fix the connector. Then, the pneumatic suction cup 35 transports the connector to the pin assembly, where the pin assembly performs the pin insertion operation on the connector. After the pin insertion operation is completed, the PLC controls the second pneumatic suction cup 35 to rotate. Cylinder 41 drives the first slider 42, causing the first slider 42 to move synchronously with the third motor 43 and the second mechanical gripper 44. The second mechanical gripper 44 approaches the connector located on the pin assembly. When the position is suitable, the second mechanical gripper 44 picks up the connector, and the second cylinder 41 drives it back to its original position. Then, the third motor 43 drives the second mechanical gripper 44 to rotate, causing it to flip 180°, thus positioning the connector above the feeding port. Afterward, the gripping state of the second mechanical gripper 44 is released, allowing the connector to fall into the feeding box 1, completing one pin insertion operation. During this process, when the connector leaves the liftable receiving platform and the pneumatic suction cup 35 moves away from the liftable receiving platform, the feeding assembly 2 will feed the second connector to be processed. The connector is pushed onto the lifting plate 19, and the first motor 15 and the first mechanical gripper 16 cooperate to place it onto the liftable receiving platform. At this time, the pneumatic suction cup 35 moves above the liftable receiving platform again, picks up the connector, and conveys it to the pin insertion assembly for pin insertion. Thus, while the pin insertion is in progress, the next connector to be processed has entered the waiting station. When the previous connector completes the pin insertion, the next connector can be quickly pinned, greatly shortening the intermediate waiting time. In summary, the feeding assembly 2 can continuously convey the connector to the lifting plate 19, and then the picking assembly 3 picks up the connector from the lifting plate 19 and conveys it to the pin insertion assembly. After the pin insertion is completed,The connector with the pin insertion completed is picked up by the unloading assembly 4 and conveyed into the unloading bin 1.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
