Description

Technical Field

[0001] The utility model relates to the technical field of PIN needle processing, in particular to a PIN needle rotary folding device. Background Art

[0002] With the rapid advancement of electronic technology, electronic products are increasingly moving towards miniaturization, lightness, and thinness. This requires electronic components, including PINs, to be smaller and more sophisticated. This trend requires continuous improvement in the accuracy and reliability of PIN feedstock breaking technology to accommodate connections within ever-smaller spaces. Furthermore, manual bending accuracy is difficult to guarantee, often resulting in significant errors in the bend position, reducing the bending accuracy of the conductive PINs. This makes it difficult to properly install the bent conductive PINs on the circuit board.

[0003] Before the PIN pin is produced, one of the sheets needs to be broken off so that it can be used. However, if the PIN pin is cut during the folding process, burrs will be generated after cutting, which will affect the use of the PIN pin. The sheet on the PIN pin needs to be broken off from the PIN pin by continuously bending it back and forth.

[0004] In the process of rotating and folding the PIN needle in the above patent, since the thickness of the PIN needle and the angle of breaking the PIN needle upper material are different, the length of the existing breaking plate is adjusted back and forth at different times, resulting in the breaking plate being unable to resist and contact the PIN needle during the breaking process, resulting in insufficient breaking length during breaking, affecting the effect of breaking the PIN needle upper material.

[0005] Therefore, it is necessary to provide a PIN needle rotating material folding device for use. Utility Model Content

[0027] Please refer to Figure 1-6 As shown; the utility model provides a technical solution for a PIN needle rotary folding device: a PIN needle rotary folding device, comprising a mounting seat 1, two symmetrically arranged mounting plates 11 are provided on the mounting seat 1, a rotary folding structure 2 is provided between the two mounting plates 11, the rotary folding structure 2 is rotatably connected to the two mounting plates 11, a PIN needle folding adjustment structure 3 is provided on the rotary folding structure 2, the PIN needle folding adjustment structure 3 is slidably fitted with the rotary folding structure 2, a PIN needle fixing structure 4 is further provided on the mounting seat 1, and the PIN needle fixing structure 4 is located between the two mounting plates 11, and an automatic PIN needle loading part 5 is provided across the two mounting plates 11.

[0028] During use, the PIN needle is moved forward to the PIN needle fixing structure 4 through the automatic PIN needle loading part 5, and the position of the PIN needle to be broken is fixed and limited by the PIN needle fixing structure 4 to prevent the position of the PIN needle from being offset in the loading channel 51 during the breaking process, affecting the effect of breaking the PIN needle material sheet. Afterwards, the PIN needle folding adjustment structure 3 can drive the position of the breaking plate 22 to move, so that the PIN needle can better contact and press the breaking plate 22, so that PIN needles of different thicknesses can be broken during the process of breaking the PIN needle. Afterwards, the rotating folding structure 2 is used to drive the breaking plate 22 to rotate to break the material sheet on the PIN needle.

[0029] In this embodiment, referring to Figure 2As shown, the rotating folding structure 2 includes a motor frame 21, a breaking plate 22, a rotating plate 23, and two rotating annular wheels 24. The motor frame 21 is horizontally mounted on one of the mounting plates 11. The mounting plate 11 is provided with a circular groove. The two rotating annular wheels 24 are rotatably connected within the circular grooves of the two mounting plates 11. The rotating plate 23 is horizontally connected to the two rotating annular wheels 24 at both ends. The motor frame 21 is provided with a reducer 25, which is equipped with a servo motor 26. The reducer 25 is provided with a rotating frame 27, which is connected to the sidewalls of the rotating annular wheels 24. The rotating plate 23 is slidably connected to the rotating plate 23. A position sensor 6 is provided on the mounting plate 11, which is positioned toward the rotating annular wheels 24. The rotating annular wheels 24 are provided with a receiving end for the position sensor 6. The position sensor 6 is connected to a controller. The model of the position sensor 6 is Positek P101.

[0030] When the PIN needle is broken, the servo motor 26 works by decelerating the reducer 25 to drive the rotating frame 27 to rotate. The rotation of the rotating frame 27 can drive one of the rotating ring wheels 24 to rotate on the mounting plate 11, thereby driving the other rotating ring wheel 24 to rotate back and forth on the mounting plate 11 through the rotating plate 23. The rotation of the rotating plate 23 can drive the breaking plate 22 to rotate back and forth to break the material on the PIN needle; and in the process of the reducer 25 driving the rotating frame 27 to rotate and thus driving the breaking plate 22 to rotate back and forth to break the material, when the receiving end of the position sensor 6 on the rotating ring wheel 24 contacts the position sensor 6, the reducer 25 stops rotating and then reverses, thereby driving the position of the breaking plate 22 to rotate back and forth in the forward and reverse directions, simulating the bending action of a human hand, and breaking the material on the PIN needle.

[0031] In this embodiment, referring to Figure 4 and Figure 5 As shown, the folding material adjustment structure 3 includes an adjustment motor 31 disposed within a rotating plate 23. An adjustment gear 32 is provided on the main shaft of the adjustment motor 31. A slide 28 is provided on the rotating plate 23, and a slider 29 is provided on the slide 28. An adjustment rack 33 is provided at the bottom of the rotating plate 23, meshing with the adjustment gear 32.

A proximity sensor electrically connected to the adjustment motor 31 is located within the PIN pin retaining groove 221. A controller electrically connected to the proximity sensor, the adjustment gear 32, and the servo motor 26 is provided on the mounting base 1. The proximity sensor model is E2E-X3D1-N-Z2M.

[0032] The adjusting motor 31 drives the adjusting gear 32 to rotate on the adjusting rack 33, so that the sliding groove 34 on the breaking plate 22 moves in the slider 29, driving the breaking plate 22 to move in the sliding groove 28 so that the PIN needle limiting groove 221 contacts and interferes with the material. After the proximity sensor senses, the electrical signal is transmitted to the controller, and the controller controls the adjusting motor 31 to stop working, so that the PIN needle limiting groove 221 provided at the end of the rotating plate 23 just contacts the material. Then the controller controls The servo motor 26 rotates back and forth to drive the rotating plate 23 to rotate, thereby breaking the material sheet on the PIN needle. When facing PIN needles of different thicknesses, the position of the breaking plate 22 can be adjusted and moved by adjusting the motor 31, so that the PIN needle limiting groove 221 at the end of the breaking plate 22 can better contact and fit with the material sheet, so that the material sheet is bent and located in the PIN needle limiting groove 221, and the material sheet on the PIN needle is completely broken, so that the breaking effect of the material sheet on the PIN needle is better and no burrs will appear.

[0033] Gear transmission can ensure a precise transmission ratio, which remains essentially constant during operation, helping to ensure the operational accuracy and stability of the entire mechanical system. For example, in the present invention, the gear transmission can precisely control the distance and position of the breaking plate, thereby ensuring the accuracy of PIN processing.

The telescopic end of the fixed cylinder 42 is provided with a T-block 46 connected to the moving block 47.

[0035] When the position of the PIN needle is fixed and limited, the fixed cylinder 42 works to drive the position of the T-block 46 to move, thereby driving the moving block 47 to move horizontally on the slide 44, so that the fixed protrusion 45 on the fixed plate 43 moves to the PIN needle, fixing the position of the PIN needle to prevent the position of the PIN needle from being offset in the loading channel 51 during the breaking process, affecting the effect of breaking the PIN needle loading sheet.
