[0023] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0024] like Figure 1-Figure 3 As shown, a feeding and distributing device for contact pins 6 of an electrical connector includes a vibration plate 1, a straight vibration feeder 2, a clamping mechanism 3 and a pressing and limiting mechanism 4;

[0025] The feed port of the direct vibration feeder 2 is connected to the discharge port of the vibration plate 1;

[0026] The clamping mechanism 3 is arranged on one side of the discharge port of the straight vibration feeder 2, and includes a translation component, a rotation component and a clamping component. The translation component is fixed, the rotation component is arranged on the translation component, and the clamping component is arranged on the rotation component. The clamping component is used to clamp the contact pin 6 at the discharge port of the straight vibration feeder 2;

[0027] The pressing and limiting mechanism 4 is provided at the discharge port of the straight vibration feeder 2 , and the pressing and limiting mechanism 4 is used for limiting the contact needle 6 .

[0028] Specifically, in this embodiment, the vibration disk 1, the straight vibration feeder 2, and the clamping mechanism 3 are all fixedly arranged on the installation base. The vibration disk 1, the straight vibration feeder 2, and the clamping mechanism 3 are arranged in sequence according to the feeding direction. The vibration disk 1 and the straight vibration feeder 2 are both commonly used equipment for those skilled in the art, and their specific structures are not repeated here. The discharge port of the vibration disk 1 is connected to the feed port of the straight vibration feeder 2. The contact needles 6 are fed into the straight vibration feeder 2 after being arranged by the vibration disk 1. The pressing limit mechanism 4 is set at the discharge port of the straight vibration feeder 2. The pressing limit mechanism 4 is used to limit the contact needles 6 that reach the discharge port of the straight vibration feeder 2 so that the contact needles 6 can stay at the discharge port of the straight vibration feeder 2 and wait for the clamping mechanism 3 to clamp them. The feeding and distribution of the contact needles 6 are completed through the transportation and clamping of the vibration disk 1, the straight vibration feeder 2, and the clamping mechanism 3. This improves production efficiency.

[0029] Preferably, the translation assembly includes a vertical telescopic rod 31 and a horizontal telescopic rod 32. The vertical telescopic rod 31 is fixed, and the horizontal telescopic rod 32 is arranged at the telescopic end of the vertical telescopic rod 31. In this embodiment, the vertical telescopic rod 31 is fixed on one side of the discharge port of the vertical vibrating feeder 2, and the horizontal telescopic rod 32 is arranged at the telescopic end of the vertical telescopic rod 31. The telescopic direction of the horizontal telescopic rod 32 is consistent with the feeding direction of the vertical vibrating feeder 2.

[0030] Preferably, both the horizontal telescopic rod 32 and the vertical telescopic rod 31 comprise pneumatic cylinders. In this embodiment, both the horizontal telescopic rod 32 and the vertical telescopic rod 31 are pneumatic cylinders. In other embodiments, the horizontal telescopic rod 32 and the vertical telescopic rod 31 may also be electric telescopic rods. Pneumatic cylinders have a relatively high actuation speed, and using pneumatic cylinders for both the horizontal telescopic rod 32 and the vertical telescopic rod 31 facilitates achieving higher production speeds.

[0031] Preferably, the rotating assembly includes a rotating cylinder 33, which is fixedly connected to the telescopic end of the horizontal telescopic rod 32. The rotating cylinder 33 is a commonly used component by those skilled in the art, and its structure is not described in detail here. In this embodiment, the rotating end of the rotating cylinder 33 rotates within a vertical plane. The rotating cylinder 33 allows the contact pin 6 to be moved from a horizontal position to a vertical position after the clamping assembly has grasped it, facilitating subsequent assembly.

[0032] Preferably, the clamp assembly includes a pneumatic clamp 34 and a clamping block 35. The pneumatic clamp 34 is connected to the rotating end of the rotary cylinder 33, and two clamping blocks 35 are located at the power output end of the pneumatic clamp 34. The pneumatic clamp 34 is a commonly used component for those skilled in the art, and its structure is not described in detail here. In this embodiment, when the rotary cylinder 33 is horizontal, the two clamping blocks 35 located at the power output end of the pneumatic clamp 34 move toward each other to clamp the contact pin 6.

[0033] Preferably, each of the two clamping blocks 35 has a receiving groove 351 on its clamping surface for accommodating the contact pin 6. In this embodiment, the two receiving grooves 351, each with a semicircular cross-section, combine to form a circular receiving cavity when the two clamping blocks 35 move toward each other to clamp the contact pin 6. The provision of the receiving grooves 351 provides greater stability when the clamping jaw assembly grips the contact pin 6.

[0034] Preferably, the pressing limit mechanism 4 includes a stopper 42 and an elastic component, and a mounting cavity 41 is vertically provided at one end of the discharge port of the straight vibration feeder 2, and the stopper 42 is vertically slidably provided in the mounting cavity 41, and the elastic component is provided in the mounting cavity 41, and the bottom of the elastic component abuts the bottom of the mounting cavity 41, and the top abuts the stopper 42, and a limiting groove 421 for limiting the contact needle 6 is provided on the stopper 42, and one end of the limiting groove 421 is connected to the discharge port of the straight vibration feeder 2, and the other end is closed.

[0035] Specifically, in this embodiment, a mounting cavity 41 is vertically provided at one end of the discharge port of the straight vibration feeder 2, the discharge port of the straight vibration feeder 2 is located on one side of the top opening of the mounting cavity 41, and a stopper 42 is vertically slidably provided in the mounting cavity 41. An elastic component is provided between the stopper 42 and the bottom of the mounting cavity 41. In this embodiment, the elastic component is a spring. When no external force is applied, the stopper 42 protrudes from the top of the mounting cavity 41 due to the elastic force of the elastic component.

[0036] A limiting groove 421 is provided on the stop block 42. The limiting groove 421 is horizontally arranged. The length direction of the limiting groove 421 is consistent with the feeding direction of the straight vibration feeder 2. One end of the limiting groove 421 is provided with an opening and the other end is closed. The limiting groove 421 is provided with an open end connected to the discharge port of the straight vibration feeder 2. The top height of the limiting groove 421 is lower than the top height of the contact pin 6 reaching the discharge port of the straight vibration feeder 2. When the contact pin 6 is limited, the lower half of the contact pin 6 is located in the limiting groove 421 and is limited by the closed end of the limiting groove 421. When the device is working, the contact pin 6 delivered by the direct vibration feeder 2 reaches the limiting groove 421 from the discharge port of the direct vibration feeder 2. Since one end of the limiting groove 421 is closed, the contact pin 6 is limited in the limiting groove 421. When the clamping mechanism 3 is working, the clamping assembly applies a downward force to the stopper 42, causing the stopper 42 to lower. At this time, the contact pin 6 is disengaged from the limiting groove 421 and can be clamped and pulled out.

[0037] Preferably, it further includes a photoelectric sensor 5 and a controller. The photoelectric sensor 5 is arranged on both sides of the discharge port of the straight vibration feeder 2. The photoelectric sensor 5 is electrically connected to the controller, and the controller is electrically connected to the clamping mechanism 3. In this embodiment, the controller can be a PLC, an industrial computer, etc. In this embodiment, the receiving end and the transmitting end of the photoelectric sensor 5 are respectively arranged on both sides of the discharge port of the straight vibration feeder 2 and are located on both sides of the installation cavity 41. In this embodiment, the photoelectric sensor 5 is a fiber optic photoelectric sensor. The optical fiber heads of the transmitting end and the receiving end of the photoelectric sensor 5 are located on both sides of the discharge port. When the contact pin 6 reaches the limiting groove 421, the upper half of the contact pin 6 protrudes out of the limiting groove 421 and triggers the photoelectric sensor 5.

[0038] The working method of this embodiment is as follows: the contact needle 6 is initially located in the vibration disk 1, and is transported to the straight vibration feeder 2 by the vibration of the vibration disk 1. The straight vibration feeder 2 further transports the contact needle 6 to the discharge port of the straight vibration feeder 2, and the contact needle 6 enters the limiting groove 421 and is limited. When the contact needle 6 reaches the limiting groove 421, the photoelectric sensor 5 is triggered, and the electrical signal of the photoelectric sensor 5 is transmitted to the controller. The controller first controls the horizontal telescopic rod 32 of the clamping jaw mechanism 3 to move to the left, and then controls the vertical telescopic rod 31 to move downward, and then controls the rotating cylinder 33 to rotate 90° counterclockwise. At this time, the clamping jaw assembly is transformed from a vertical state to a horizontal state, and the clamping jaw The clamping block 35 of the assembly abuts against the block 42, causing the block 42 to move downward, thereby causing the contact pin 6 to disengage from the limiting groove 421. At this time, the controller controls the pneumatic clamping jaws 34 to clamp the two clamping blocks 35 to clamp the contact pin 6. Then the controller controls the horizontal telescopic rod 32 to move to the right, pulling out the contact pin 6, and then controls the vertical telescopic rod 31 to move upward, causing the clamping jaw assembly to disengage from the block 42. The block 42 rises again under the elastic force of the elastic component to limit the subsequent contact pin 6. Then, the rotary cylinder 33 is controlled to rotate 90° clockwise, so that the clamped contact pin 6 is changed from a horizontal state to a vertical state, completing the loading and distribution of the contact pin 6, which is convenient for the subsequent assembly of the electrical connector.

Any person skilled in the art can, without departing from the scope of the present invention, utilize the above-described technical content to make many possible changes and modifications to the present invention, or modify it into an equivalent embodiment with equivalent variations. Therefore, any changes, modifications, equivalent variations, and modifications made to the above embodiments based on the technology of the present invention that do not depart from the content of the present invention are within the scope of protection of the present invention.
