Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic assembly, in particular to an electronic component pin shearing auxiliary tool and a using method thereof. BACKGROUND

[0002] For electronic assembly in the field of aerospace, the shaping link of electronic components is crucial. At present, electronic components are mostly rectangular, and the pins are mostly on both sides or around the device body in a horizontal state. Such devices with pins in this state cannot be directly assembled and need to be combined with the size of the printed board pads and the specified parameters such as the shaping shoulder width, the station height, and the welding surface length, etc. to use electronic component shaping equipment and shaping tools to process the pins.

[0003] Since the pin bending and shearing structure of the shaping equipment is single-sided shaping, it can only process the pins of the electronic components on one side according to the set shaping parameters. For the pins of the electronic components on the other side, the electronic components need to be manually taken off from the vertical fixture, turned over, placed on the vertical fixture again, adjusted to the appropriate position, and pressed tightly against the fixture cover plate, and finally shaped in the other direction. In addition, the existing vertical fixture lacks adjustment function and cannot adapt to electronic components of different models.

[0004] In the above process, the electronic component pins are often not on the same horizontal line due to manual turning or deviation in the placement angle, or the pins are not perpendicular to the shearing direction, which causes the overall deformation of the electronic component pins or the inconsistency in the length of the pins after shearing, resulting in the inability to accurately position the electronic component pins and the printed board pads. At the same time, for the common shaping of multiple electronic components of the same type, the manual turning method consumes a lot of time and it is difficult to ensure that the lengths of the pins of all electronic components exposed outside the vertical fixture are consistent. The more the number of electronic components, the more obvious the problem. This human error condition can easily cause the parameters of the pins and the lap length of the pads to not meet the relevant requirements, thereby increasing the failure rate of shaping and reducing production efficiency.

The distance adjustment component 21 is used to adjust the distance between the first clamping member 22 and the second clamping member 23.

[0036] Specifically, the distance adjustment assembly 21 includes a first cross arm 211, a second cross arm 212, and a connecting bolt 213. A through connecting hole is provided at the middle position of the first cross arm 211 and the second cross arm 212. The connecting bolt 213 passes through the connecting holes of the first cross arm 211 and the second cross arm 212 in sequence, so that the first cross arm 211 and the second cross arm 212 are cross-hinged, and the first cross arm 211 and the second cross arm 212 are locked by a third nut.

[0037] The first cross arm 211 is provided with a first pin hole 2111 at one end and a first sliding shaft 2112 at the other end. The second cross arm 212 is provided with a second pin hole at one end and a second sliding shaft at the other end. The first pin hole 2111 of the first cross arm 211 and the second sliding shaft of the second cross arm 212 are jointly connected to the first clamping piece 22. The second pin hole of the second cross arm 212 and the first sliding shaft 2112 of the first cross arm 211 are jointly connected to the second clamping piece 23.

[0038] In the embodiment, the first cross arm 211 and the second cross arm 212 are both provided with grooves. When the first cross arm 211 and the second cross arm 212 intersect, the second cross arm 212 is located above the first cross arm 211, and the grooves of the two cross arms are arranged in an upper and lower relationship.

[0039] In some embodiments, the first cross arm 211 and the second cross arm 212 are not provided with grooves, and are directly connected by the connecting bolt 213 when intersected.

[0040] The first clamping piece 22 and the second clamping piece 23 are symmetrical to each other and both include a connecting portion 221 and a lapping portion 222 perpendicular to each other, so as to form an L-shaped structure. One of the first clamping piece 22 and the second clamping piece 23 is fixed to the base 1, and the other of the first clamping piece 22 and the second clamping piece 23 is movably arranged on the base 1.

[0041] The upper surface of the connecting portion 221 of the first clamping piece 22 is provided with a first long slot 223, a first positioning pin 224, and a first plug-in slot 225 matched with the connecting column 242. The upper surface of the connecting portion 221 of the second clamping piece 23 is provided with a second long slot, a second positioning pin, and a second plug-in slot matched with the connecting column 242.

[0042] The first pin hole 2111 is sleeved on the first positioning pin 224, so that the first cross arm 211 is hinged with the first positioning pin 224. The first sliding shaft 2112 of the first cross arm 211 is embedded in the second long slot, and the first sliding shaft 2112 can slide along the second long slot.

[0043] The second cross arm 212 is hinged to the second positioning pin through the second pin hole, and the second sliding shaft of the second cross arm 212 is embedded in the first long slot 223, and the second sliding shaft can slide along the first long slot 223.

[0044] After the connecting bolt 213 is loosened, the first sliding shaft 2112 and the second sliding shaft respectively slide in the corresponding long slots, so as to adjust the distance between the first clamping piece 22 and the second clamping piece 23 at the angle between the first cross arm 211 and the second cross arm 212.

[0045] The lower surface of the connecting portion 221 of the first clamping member 22 is provided with a first positioning hole 226 which is adapted to the limiting shaft 14. The lower surface of the connecting portion 221 of the second clamping member 23 is provided with a second positioning hole which is adapted to the limiting shaft 14.

When the second positioning hole is sleeved on the limiting shaft 14, the second clamping member 23 is fixedly connected with the base 1, and the first clamping member 22 is movably arranged on the base 1. By changing the connection mode of the first clamping member 22 and the second clamping member 23, the 180° rotation of the clamping mechanism 2 is realized.

The connecting column 242 is inserted into the first insertion slot 225 or the second insertion slot, so that the element pressing plate assembly 24 is connected to the first clamping member 22 or the second clamping member 23.

[0049] It should be noted that when the pins of the electronic element 4 extend from both ends of the electronic element 4, the element pressing plate assembly 24 is not needed. At this time, the pins of the electronic element 4 are respectively overlapped on the overlapping portions 222 of the first clamping member 22 and the second clamping member 23, and the two overlapping portions 222 press the two ends of the electronic element 4 respectively.

[0050] When the pins of the electronic element 4 extend from the bottom to both ends of the electronic element 4, the element pressing plate assembly 24 is needed to fix the electronic element 4. The two end pins of the electronic element 4 are also overlapped on the overlapping portions 222 of the two clamping members, but the pressing plate 241 of the element pressing plate assembly 24 is also needed to press the electronic element 4, so as to prevent the electronic element 4 from being dislocated or falling off during the 180° rotation of the clamping mechanism 2 together with the clamped electronic element 4.

[0051] The pin pressing mechanism 3 further comprises a moving plate 31, a cover plate 32, a vertical plate 33, a rotating shaft 34 and a screw rod 35.

[0052] The bottom of the vertical plate 33 is connected with one end of the moving plate 31, and the cover plate 32 is rotatably connected with the top of the vertical plate 33 through the rotating shaft 34.

The pressing block 321 is used to press the pins of the electronic component 4 when the cover plate 32 is closed. The cover plate 32 is further provided with an elongated hole 322.

[0054] The screw rod 35 is erected on the moving plate 31. When fixed, the top end of the screw rod 35 passes through the elongated hole 322 of the cover plate 32, the first nut is screwed into the screw rod 35 and tightened, and the cover plate 32 is fastened. When loosened, the first nut is loosened first, and the cover plate 32 can be rotated around the rotating shaft 34. The elongated hole 322 provides a moving space for the rotation, so that the cover plate 32 can be separated from the screw rod 35.

[0055] A method for using an electronic component pin shearing auxiliary tool is realized by using the above-mentioned electronic component pin shearing auxiliary tool, comprising the following steps: S1: placing the electronic component 4 on the clamping mechanism 2, adjusting the distance adjusting assembly 21 of the clamping mechanism 2, so that the first clamping piece 22 and the second clamping piece 23 of the clamping mechanism 2 clamp the two ends of the electronic component 4.

[0056] Specifically, the connecting bolt 213 is loosened, the first cross arm 211 and the second cross arm 212 make a shearing motion around the connecting bolt 213, the distance between the first clamping piece 22 and the second clamping piece 23 is adjusted, and then the two ends of the electronic component 4 are clamped.

[0057] S2: moving the pin pressing mechanism 3, so that the pin pressing mechanism 3 contacts with the distance adjusting assembly 21; rotating the cover plate 32 to make the pressing block 321 press the pins of the electronic component 4 close to the pin pressing mechanism 3, and then screwing the first nut into the screw rod 35 of the pin pressing mechanism 3 and tightening.

[0058] Specifically, the pin pressing mechanism 3 is moved along the sliding groove 13 of the base 1, the front end of the moving plate 31 is contacted with the first clamping member 22, the cover plate 32 is rotated to press the pin pressing block 321 against the pin on the side of the electronic component 4 close to the pin pressing mechanism 3, the first nut is screwed into the screw rod 35 and tightened, and the cover plate 32 is fastened.
