Description

[0002] Existing electronic products all involve connecting wires between electronic components and circuit boards. The connecting wires can be directly plugged in and used, which is very convenient to use. Its structure usually includes a wire and a plastic shell. One end of the wire has solder and the other end has a terminal. The terminal is inserted into the plastic shell to form a connecting wire.

[0003] The processing of connecting wires needs to go through multiple processes such as wire stripping, wire cutting, terminal punching, and plugging in plastic shells. The prior art has various devices for plugging in plastic shells. In order to smoothly insert the plastic shells, the existing devices for plugging in plastic shells need to design a positioning fixture to position the plastic shells, and then insert the terminals of the connecting wires into the plastic shells. In this way, for plastic shells with different PIN pin hole spacings, their shapes and sizes are different, and different positioning fixtures need to be designed for positioning, which makes the positioning fixture not applicable and has poor performance. As a result, for plastic shells with different types of shapes and PIN pin hole spacings, different positioning fixtures need to be replaced for the plugging process of the plastic shells, which increases the design cost, reduces the production efficiency, and makes positioning more difficult.

In this way, by arranging the second plug pin 41 on the rotation positioning unit 46, it is possible to realize the rotation conversion of different second plug pins 41, so that when one second plug pin 41 is relatively inserted into the second positioning hole 72 of the plastic shell, another plastic shell with the second plug pin 41 inserted can be rotated to the next station for the terminal plug shell process, and the remaining second plug pins 41 are in a standby state, so that the work efficiency can be improved, the idle time can be avoided, the manufacturing cost can be saved, and the plastic shell with the second plug pin 41 inserted can be rotated to the next station. In addition, here, it is preferred to have four rotation positioning units 46, and the rotation angle of each rotation positioning unit 46 from the second plug pin 41 insertion plastic shell station to the terminal plug plastic shell station is preferably 90°.

[0080] Each rotation positioning unit 46 includes a base block 461 and a positioning frame 462, a positioning block 463, a second slide rail 464, a second slider 465, a second slide seat 466, a return spring 467, and a guide rod 468 installed on the base block 461.

Thus, by combining the second slide rail 464, the second slider 465, the return spring 467 and the guide rod 468, when the terminal is inserted toward the plastic shell (or the plastic shell is inserted toward the terminal), the linkage part provided by the mechanism for fixing the terminal acts on the second slide seat 466 (or the second slider 465), so that the second slider 465 moves relative to the second slide rail 464 to drive the second plug pin 41 to move out of the second positioning hole 72 to make room for the terminal so that the terminal can be smoothly inserted into the first positioning hole 71; here, when the terminal is inserted into the plastic shell, there is a pre-insertion, that is, the terminal is inserted to a first depth in the first positioning hole 71 of the plastic shell to achieve pre-insertion, and then the terminal is further inserted to the second depth. At the same time, as the terminal continues to be inserted, the second plug pin 41 gradually withdraws from the plastic shell to make room for the terminal so that the terminal can be completely inserted into the first positioning hole 71 of the plastic shell. In addition, the second plug pin 41 is detachably positioned on the second slide seat 466, so that different second plug pins 41 can be replaced to adapt to plastic shells with different PIN pin spacings. It is only necessary to replace the second plug pin 41 according to actual needs.

[0081] The second conversion positioning mechanism also includes an auxiliary positioning unit 60, which is installed on the second conversion seat 42. The auxiliary positioning unit 60 includes an auxiliary positioning rod 61 and an auxiliary driving unit 62 for driving the auxiliary positioning rod 61. The auxiliary driving unit 62 drives the auxiliary positioning rod 61 to make a linear motion, so that the auxiliary positioning rod 61 can selectively act on a number of auxiliary limiting holes 451 correspondingly arranged on the rotating seat 45, so that the rotating seat 45 can be firmly positioned after rotating 90°.

[0082] Furthermore, the first mobile drive unit 36, the second mobile drive unit 56, the first drive unit 22, the second drive unit 43, and the auxiliary drive unit 62 are preferably driven by motors, and the remaining drive units are preferably driven by cylinders. Of course, the above-mentioned drive settings are not limited and can be set according to actual production needs, as long as the corresponding drive is met.

[0083] The above-mentioned plastic shell conversion method adopted by the plastic shell conversion device includes the following steps:

[0084] Step 1: The plastic shell conveying mechanism 10 conveys the plastic shell 70 until the plastic shell 70 is conveyed to the pre-positioning unit 13 for pre-positioning;

[0085] Step 2: The first driving unit 22 drives the first plug pin 21 to move toward the pre-positioned plastic shell 70 in the pre-positioning unit 13, so that the first plug pin 21 is inserted into the first positioning hole 71 of the plastic shell 70 for plugging the terminal, so as to form the positioning of the plastic shell 70 by the first plug pin 21; then, the first moving unit 30 drives the plastic shell 70 with the first plug pin 21 inserted to move as a whole to one side of the second conversion positioning mechanism;

[0086] Step 3: The second plug pin 41 is relatively displaced toward the plastic shell 70 into which the first plug pin 21 has been inserted (here, the first driving unit 22 drives the plastic shell 70 into which the first plug pin 21 has been inserted to move toward the second plug pin 41 of the second conversion positioning mechanism, and the second plug pin 41 is fixed), so that the second plug pin 41 is inserted into the second positioning hole 72 of the plastic shell 70. At the same time, the linkage unit 23 links the first plug pin 21 to move away from the plastic shell 70 to exit the first positioning hole 71, so as to form the second plug pin 41 to position the plastic shell 70, and the first plug pin 21 to release the plastic shell 70. At this time, one end of the second plug pin 41 extends into the first positioning hole 71 through the second positioning hole 72, so that the second plug pin 41 can better position the plastic shell 70 firmly. Then, the second driving unit 43 drives the rotating seat 45 to rotate to drive the plastic shell 70 into which the second plug pin 41 has been inserted to rotate to the next station to carry out the terminal plugging plastic shell process.

[0087] To sum up, the design focus of the present invention is that it is mainly through the combined design of the plastic shell conveying mechanism, the first plug pin and the second plug pin, and the first plug pin and the second plug pin are respectively inserted and positioned with the relative first positioning hole and the second positioning hole of the plastic shell, so that the conversion of different positioning directions of the plastic shell is realized, especially, the positioning of the plug pin can be applicable to plastic shells with the same type of PIN pin pinhole spacing, so that when it is applicable to plastic shells with different numbers of PIN pins, it is only necessary to increase the number of plug pins, and there is no need to consider the shape of the plastic shell, so there is no need to design a positioning fixture for plastic shells with the same type of PIN pin holes but different shapes, thereby reducing the design cost, and there is no need to replace the plug pin for the conversion positioning of plastic shells with the same type of PIN pin pinhole spacing, thereby improving work efficiency, and the pin positioning is simpler and more stable.

[0088] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
