Description

Technical Field

[0001] This application relates to the technical field of terminal production equipment, and in particular to an automatic terminal feeding mechanism. Background Technology

[0002] Currently, cold-pressed terminals, also known as crimp terminals or cold-pressed wiring terminals, are metal connectors used for electrical connections. They tightly connect wires to terminals using mechanical pressure without the need for welding or other heat treatment methods, hence the name "cold-pressed."

[0003] Among the related technologies, there is a cold-pressed terminal whose structure mainly includes a conductive end and an insulating sleeve that is injection molded at one end of the conductive end. To facilitate subsequent transportation, material strips are also injection molded between each insulating sleeve. The insulating sleeves are connected and fixed in sequence by the material strips to form a connected terminal.

[0004] When processing the terminals, a feeding mechanism is usually used to feed the neatly arranged, equidistant conductive ends into the corresponding injection holes of the injection mold. The feeding mechanism is equipped with multiple drop holes arranged in sequence at intervals. Each drop hole is equipped with a conveying pipe, which is used to feed the conductive ends into the drop holes in sequence. Finally, the conductive ends in each injection hole are simultaneously fed into the corresponding injection holes of the injection mold.

[0005] Regarding the aforementioned feeding mechanism, when the interval between adjacent injection holes on the injection mold is smaller than the interval between discharge holes, the feeding mechanism cannot accurately feed the conductive end into the corresponding injection hole due to the limitation of the discharge hole position. Therefore, it has certain limitations and a limited range of applications. Utility Model Content

The feeding platform has multiple equally spaced discharge holes. A sliding cylinder is mounted on the mounting frame, and its piston rod is fixedly connected to the feeding platform. The sliding cylinder drives the feeding platform to move in a straight line. A baffle plate is slidably mounted on the bottom of the mounting frame. A guide rod cylinder is mounted on the mounting frame to drive the baffle plate to slide, and its piston rod is linked to the baffle plate.

[0008] Preferably, the mounting bracket is provided with a guide rail, the length of which extends along the sliding direction of the loading platform; the loading platform is provided with a sliding seat, which is slidably mounted on the guide rail, and the piston rod of the sliding cylinder is mounted on the sliding seat.

[0016] The present application will be further described in detail below with reference to the accompanying drawings.

[0017] This application discloses an automatic terminal feeding mechanism.

[0018] Reference Figure 1 , Figure 2 The automatic terminal feeding mechanism includes a mounting frame 1, on which a horizontally placed feeding platform 2 is movably mounted. Multiple discharge holes 20 are equidistantly arranged along the length of the feeding platform 2, connecting the top and bottom of the platform. Two sets of guide rails 6 are also fixedly mounted on the mounting frame 1, symmetrically arranged on the left and right sides of the feeding platform 2. The guide rails 6 extend along the length of the feeding platform 2, and sliding seats 7 are fixedly mounted at both ends of the feeding platform 2, slidingly mounted on their respective opposite guide rails 6.

[0019] like Figure 1 , Figure 2 As shown, a sliding cylinder 3 is fixedly mounted on the mounting frame 1. The piston rod of the sliding cylinder 3 extends along the sliding direction of the sliding seat 7, and the piston rod of the sliding cylinder 3 is fixedly mounted on one side of the sliding seat 7. The sliding cylinder 3 is used to drive the loading platform 2 to move horizontally along the length direction of the guide rail 6. A displacement sensor 10 is also fixedly mounted on the mounting frame 1, with the detection end of the displacement sensor 10 facing the sliding seat 7 on the other side. The displacement sensor 10 is used to detect the displacement of the loading platform 2 and transmit the detected displacement to the central processing unit in real time. The displacement sensor 10 establishes signal communication with the sliding cylinder 3 through the central processing unit, which is used to control the extension and retraction of the piston rod of the sliding cylinder 3. The central processing unit may include a CPU or MPU or a host system built around a CPU or MPU, including hardware or software. Users can freely control the above modules by programming, making them operate according to their wishes. Local measurement / traceability components, remote measurement / traceability components, and remote communication components can also be controlled through internal protocols. Internal protocols may include some or all of the following: human-machine interaction protocols, software / hardware (interface) protocols, chip bus (C-Bus) protocols, internal bus (I-Bus) protocols, etc. With the development of integrated circuit technology, some protocols that belong to external bus (E-Bus) have also been classified as internal protocols after the external bus (E-Bus) is integrated into the chip.

[0020] like Figure 1 , Figure 2 As shown, a baffle seat 8 is fixedly installed on the mounting bracket 1 on one side of the sliding seat 7. The baffle seat 8 is located on the sliding path of one of the sliding seats 7, and the baffle seat 8 is used to limit the maximum displacement range of the loading platform 2 to prevent the sliding seats 7 from detaching from their respective guide rails 6.

[0021] like Figure 1 , Figure 2As shown, two guide rods 11 are fixedly installed on the mounting frame 1, and the guide rods 11 are symmetrically arranged on the left and right sides of the loading platform 2. The length direction of the guide rods 11 is perpendicular to the length direction of the loading platform 2. A baffle plate 4 is provided between the two guide rods 11 to block the bottom opening of the material drop hole 20. The left and right ends of the baffle plate 4 are slidably mounted on the corresponding guide rods 11, and the baffle plate 4 moves along the length direction of the two guide rods 11.

[0022] like Figure 1 , Figure 2 As shown, a return spring 12 is coaxially sleeved on the outside of the guide rod 11. The return spring 12 extends and retracts along the length of the guide rod 11. One end of the return spring 12 abuts against the guide rod 11, and the other end of the return spring 12 abuts against the outer wall of the baffle plate 4. The return springs 12 on both sides are used to synchronously push the baffle plate 4 to close the bottom opening of the discharge hole 20.

[0023] like Figure 1 , Figure 2 As shown, a linkage plate 40 extending upwards to the top of the mounting frame 1 is fixedly installed on one side of the baffle plate 4. Two sets of guide rod cylinders 5 for synchronously driving the sliding of the baffle plate 4 are fixedly installed on the upper surface of the mounting frame 1. The guide rod cylinders 5 are symmetrically arranged on the left and right sides of the mounting frame 1. The same baffle 50 is fixedly installed on the piston rod of the two sets of guide rod cylinders 5. The baffle 50 is directly opposite the linkage plate 40, and the extension and retraction direction of the piston rod of the guide rod cylinder 5 is consistent with the sliding direction of the baffle plate 4. The linkage plate 40 is located on the sliding path of the baffle 50 moving away from the loading platform 2, and the baffle 50 is used to push the linkage plate 40 and the baffle plate 4 to move in a direction that overcomes the reset force of the reset spring 12, until the baffle plate 4 is moved out of the bottom opening of the drop hole 20. At this time, the conductive end located in the drop hole 20 can fall off the loading platform 2 under its own gravity. The guide rod cylinders 5 are also controlled by the central processing unit.

[0024] It should be mentioned that the distance between the central axes of two adjacent blanking holes 20 is an integer multiple of the distance between the central axes of two adjacent injection holes on the injection mold.

[0025] The implementation principle is as follows: This embodiment uses the example where the distance between the central axes of two adjacent drop holes 20 is twice the distance between the central axes of two adjacent injection holes. When the conductive terminals fall into their respective drop holes 20 through their respective feed pipes, the conductive terminals will be limited and stopped within the loading platform 2 by the lower baffle plate 4. Subsequently, the mounting frame 1 will be moved to the designated loading position of the injection mold under the drive of the external lifting mechanism. The specific external lifting mechanism can be implemented by a lifting cylinder, which will not be described in detail here.

[0026] Once the loading platform 2 reaches the designated loading station, the discharge holes 20 are aligned with the odd-numbered injection holes (first, third, fifth, seventh, etc.). Then, the guide cylinder 5 controls the baffle plate 4 to open, allowing the conductive terminals to fall into their corresponding injection holes. Next, the piston rod of the guide cylinder 5 is extended, causing the baffle plate 4 to retract under the force of the return spring 12, closing the bottom opening of the discharge holes 20 again. The next batch of conductive terminals is then added to each discharge hole 20. The sliding cylinder 3 then moves the loading platform 2 along the length of the guide rail 6 until the discharge holes 20 are aligned with the even-numbered injection holes (second, fourth, sixth, eighth, etc.). This loading process is repeated, ensuring the conductive terminals are placed smoothly and accurately into each injection hole, further expanding the compatibility of the conductive terminals and meeting the loading requirements of various injection mold specifications.

[0027] The baffle plate 4 is reset by the reset spring 12, which can block the bottom opening of the material drop hole 20 in time, and also ensure that the conductive terminals are not bent or deformed due to hard compression when the baffle plate 4 is reset.

[0028] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
