Description

Technical Field

[0002] Terminals and shells are important components of connectors. Terminals and shells are generally assembled and produced using automatic assembly equipment to improve production efficiency and reduce labor costs. A connector is usually provided with multiple terminals to achieve multi-point connection. In the process of inserting multiple terminals into the shell, an existing automatic assembly device is to insert multiple terminals into the shell at the same time to ensure that all terminals can be accurately inserted into the shell. This type of automatic assembly equipment is a vibration disk feeding type, that is, after the terminal strip is cut, it is collected in the vibration disk, and the vibration disk then provides the terminal to the clamping mechanism. This type of automatic assembly equipment occupies a large area, and an additional vibration disk is added, and the overall equipment cost is higher. Therefore, in order to reduce equipment costs, a material strip feeding type automatic assembly equipment is usually selected, that is, the automatic assembly equipment directly processes the terminal strip directly, and no additional vibration disk is required.

[0045] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] The terminal strip is composed of a number of terminals and a bridge connecting two adjacent terminals.

[0047] A cavity is arranged inside the plastic shell.

[0048] like Figures 1 to 9As shown, the present embodiment provides an automatic plug-in machine for terminal plastic shells, which includes a carrier 1, on which a pushing mechanism 2, a cutting mechanism 3, a displacement mechanism 4 and a clamping and transferring mechanism 5 are arranged, the pushing mechanism 2 is used to push the terminal strip; the cutting mechanism 3 is located downstream of the pushing mechanism 2, and is used to cut the material bridge of the terminal strip; a pressing mechanism 6 is installed on the displacement mechanism 4, and the pressing mechanism 6 is used to press the plastic shell, and the displacement mechanism 4 is used to drive the pressing mechanism 6 to move along the Y-axis direction; the clamping and transferring mechanism 5 is located on one side of the cutting mechanism 3, and is used to clamp the terminal cut by the cutting mechanism 3 and insert the terminal into the plastic shell along the X-axis direction.

[0049] The pushing mechanism 2 pushes the terminal strip to the bottom of the cutting mechanism 3, and the cutting mechanism 3 cuts off the material bridge of the terminal strip to obtain a single terminal. The clamping and transferring mechanism 5 clamps the terminal and inserts it into the plastic shell. Generally, a plastic shell needs to be inserted with several terminals. Therefore, after the current terminal is inserted into the plastic shell, the displacement mechanism 4 drives the pressing mechanism 6 to move a preset distance along the Y-axis direction. The terminal clamped again by the clamping and transferring mechanism 5 from the cutting mechanism 3 can be inserted into another position inside the plastic shell until a preset number of terminals are inserted into the shell of the plastic shell. In the process of inserting the terminal into the plastic shell, the pressing mechanism 6 can press the plastic shell tightly to avoid unstable insertion of the terminal and ensure assembly quality.

Each ratchet tooth of the ratchet 22 corresponds to a terminal, which can ensure the accuracy of the feeding position, so that the cutting mechanism 3 can accurately cut the material bridge without damaging the terminal, and the use of the ratchet 22 to feed can ensure the stability of the forward speed of the terminal strip.

[0051] like Figure 4 As shown, the specific structure of the cutting mechanism 3 of this embodiment can refer to the existing stamping die assembly, and this embodiment will not be repeated one by one.

[0052] like Figure 5 As shown, optionally, the displacement mechanism 4 includes a sixth power member 41 and a second support member 42, the clamping assembly 61 is mounted on the second support member 42, the second support member 42 is connected to the output end of the sixth power member 41, and the sixth power member 41 is used to drive the second support member 42 to move along the Y-axis direction. Optionally, the second support member 42 is a support plate.

[0053] Optionally, a third support member 43 is installed on one side of the second support member 42 close to the clamping transfer mechanism 5, and the third support member 43 is used to support the plastic shell. Optionally, the third support member 43 is a support seat.

[0054] like Figure 6 As shown, optionally, the clamping and transferring mechanism 5 includes a first power member 51, a second power member 52, a third power member 53, a first supporting plate 54 and a first clamping plate 55, the second power member 52 is installed at the output end of the first power member 51, the first power member 51 is used to drive the second power member 52 to move along the Y-axis direction, the third power member 53 and the first supporting plate 54 are both installed at the output end of the second power member 52, the second power member 52 is used to drive the third power member 53 and the first supporting plate 54 to approach the pressing mechanism 6 along the X-axis direction, the first clamping plate 55 is installed at the output end of the third power member 53, and the third power member 53 is used to drive the first clamping plate 55 to clamp the terminal on the first supporting plate 54 in the Z-axis direction.

[0055] After the cutting mechanism 3 cuts the terminal strip to obtain the terminal, the first power member 51 drives the second power member 52, the third power member 53, the first carrier plate 54 and the first clamping plate 55 to approach the cutting mechanism 3 along the Y-axis direction, the first clamping plate 55 moves to the top of the terminal, the first carrier plate 54 moves to the bottom of the terminal, the third power member 53 drives the first clamping plate 55 in the Z-axis direction to press the terminal onto the first carrier plate 54, thereby clamping the terminal, the first power member 51 drives the second power member 52, the third power member 53, the first carrier plate 54 and the first clamping plate 55 away from the cutting mechanism 3 in the opposite direction of the Y-axis and returns to its original position, the second power member 52 drives the third power member 53, the first clamping plate 55 and the first carrier plate 54 to drive the terminal to be inserted into the plastic shell along the X-axis direction, completing the plug-in assembly of the terminal and the plastic shell.

[0056] like Figure 7 As shown, optionally, the pressing mechanism 6 includes a clamping assembly 61 and a support assembly 62, the support assembly 62 includes a fourth power member 621 and a first support member 622, the first support member 622 and the clamping assembly 61 are both installed at the output end of the fourth power member 621, the fourth power member 621 is used to drive the first support member 622 to extend into the shell of the plastic shell in the X-axis direction and to move the clamping assembly 61 to the top of the plastic shell, and the clamping assembly 61 is used to clamp the plastic shell in the Z-axis direction.

[0057] When assembling the terminal and the plastic shell, it is necessary to ensure the clamping force of the plastic shell on the terminal. Therefore, when the terminal is inserted into the plastic shell, the plastic shell is subjected to a certain thrust, and the terminal is subjected to a reaction force. Therefore, in this embodiment, the plastic shell is pressed by the clamping component 61 to prevent the plastic shell from shifting when subjected to the thrust, resulting in the terminal being unable to be accurately inserted.

[0058] The plastic shell is provided with a cavity inside. When the pressing assembly 61 presses the plastic shell, there is a risk of crushing the plastic shell. Therefore, the first support member 622 is provided in this embodiment to support the plastic shell. The first support member 622 is a support platform. After the external mechanism places the plastic shell on the support assembly 62, the fourth power member 621 drives the first support member 622 to extend into the plastic shell to support the plastic shell and prevent the plastic shell from being crushed when the pressing assembly 61 presses and fixes the plastic shell. Whenever the clamping transfer mechanism 5 inserts a terminal into the plastic shell, the displacement mechanism 4 drives the support assembly 62 and the plastic shell to move a preset distance along the Y-axis direction.

[0059] Optionally, the clamping assembly 61 includes a fifth power member 611, a second clamping plate 612 and a transition plate 613. The transition plate 613 is provided with an arc groove 6131. ​​The plane where the arc groove 6131 is located is the XZ plane. The output end of the fifth power member 611 is connected to the arc groove 6131. ​​The second clamping plate 612 is connected to one end of the transition plate 613 close to the plastic shell. The fifth power member 611 is used to drive the transition plate 613 to rotate in the XZ plane to drive the second clamping plate 612 to clamp or loosen the plastic shell in the Z-axis direction.

[0060] A connecting pin 614 is provided at the output end of the fifth power member 611, and one end of the connecting pin 614 extends into the arc groove 6131. ​​When the fifth power member 611 drives the connecting pin 614 to move along the X-axis direction, one end of the transition plate 613 connected to the second clamping plate 612 rises or sinks, thereby driving the second clamping plate 612 to loosen or clamp the rubber shell.

[0061] like Figure 8 and Fig. 9 As shown, optionally, a lifting mechanism 7 is further provided on the carrier 1, and the lifting mechanism 7 includes a seventh power member 71, and the displacement mechanism 4 is connected to the output end of the seventh power member 71, and the seventh power member 71 is used to drive the displacement mechanism 4 to move in the Z-axis direction. When the type of the plastic shell is changed, the thickness of the plastic shell increases or decreases, so it is necessary to adjust the horizontal height of the displacement mechanism 4 and the pressing mechanism 6. The seventh power member 71 drives the displacement mechanism 4 to move in the Z-axis direction, and the horizontal height of the displacement mechanism 4 and the pressing mechanism 6 can be adjusted.
