Description

Technical Field

[0001] The utility model relates to the technical field of electronic component processing, in particular to a device for bending pins of electronic components. Background Art

[0002] Electronic components are components of electronic devices and small machines and instruments. They are usually made up of several parts and can be used in similar products. Before soldering them to the PCB board, the pins of the electronic components usually need to be bent into shape. The components of the PCB substrate are soldered to the PCB substrate using pins. The pins need to be bent during production to facilitate soldering. However, traditional pin bending devices have a large impact force in actual use, which can easily damage the component body. In addition, since electronic components are often small in size, it is inconvenient to remove the electronic component pins after bending.

[0003] A search revealed a Chinese patent document, such as the one disclosed in CN202321790195.5, which describes a device for bending the pins of electronic components. The device comprises a support seat having a clearance groove formed therein, a support positioning seat slidably connected thereto, a limiting edge strip fixedly connected to the outer side of the support positioning seat, an adjustable extrusion seat disposed above the support positioning seat, and a bending block disposed on the outer side of the adjustable extrusion seat.

[0004] The device disclosed in this patent can limit the position of electronic components and reduce the impact on electronic components when bending leads. However, when the device is in use, the positions of the bending block and the limiting edge strip are relatively fixed. When the device is in use, smaller electronic components are difficult to obtain the limiting control of the limiting edge strip, and the bending block is inconvenient to bend shorter leads. Therefore, the flexibility of the device in use is relatively poor, that is, the device is not convenient for processing and using electronic components of different sizes. The device has certain limitations when used. Utility Model Content

When the positioning plate 93 contacts the top of the electronic component, the position of the electronic component can be restricted to prepare for the subsequent bending of the leads of the electronic component.

[0030] The auxiliary mechanism 12 includes an auxiliary rod 121, a disc 122 and a third compression spring 123. The surface of the auxiliary rod 121 is slidably connected to the inner wall of the slide groove, the disc 122 is fixedly connected to the bottom of the auxiliary rod 121, the surface of the disc 122 is slidably connected to the inner wall of the slide groove, the two ends of the third compression spring 123 are respectively fixedly connected to the bottom of the disc 122 and the bottom of the inner wall of the slide groove, and the storage plate 13 is fixedly connected to the top of the auxiliary rod 121. When the positioning mechanism 9 contacts the electronic components and the pressure block 8 contacts the leads of the electronic components, the cross plate 5 continues to descend. At this time, the storage plate 13 is forced to descend. The auxiliary mechanism 12 can guide the descent of the storage plate 13 and reduce the impact of the storage plate 13 when it falls directly. Guide rods 14 are fixedly connected to both sides of the bottom of the storage plate 13. The surface of the guide rods 14 contacts the inner wall of the guide groove. The setting of the guide rods 14 can increase the stability of the movement of the storage plate 13.

[0031] The reset mechanism 15 includes a polished rod 151, a T-shaped plate 152 and a fourth compression spring 153. The two ends of the polished rod 151 are fixedly connected to the two sides of the inner wall of the storage groove, and the surface of the T-shaped plate 152 is slidably connected to the inner wall of the storage groove.

The connecting rod 16 is fixedly connected to the surface of the T-shaped plate 152. When the staff moves the support mechanism 17, the connecting rod 16 drives the T-shaped plate 152 to move. At this time, the fourth compression spring 153 is shortened by force. Subsequently, under the action of the elastic force of the fourth compression spring 153, the two connecting rods 16 move toward opposite sides to limit the electronic components through the support mechanism 17.

[0032] The supporting mechanism 17 includes a column 171, a rotating plate 172 and a supporting plate 173. The column 171 is fixedly connected to the top of the connecting rod 16, the rotating plate 172 is rotatably sleeved on the surface of the column 171, and the supporting plate 173 is fixedly connected to the surface of the rotating plate 172. After the staff rotates the rotating plate 172, the two supporting plates 173 are arranged opposite to each other. At this time, when the staff places the electronic components on the top of the storage plate 13, the two supporting plates 173 can respectively support the two sides of the bottom of the electronic components, and the two rotating plates 172 can cooperate to clamp the electronic components. At this time, the leads on both sides of the electronic components are in contact with the top of the rotating plate 172. Thereafter, the leads of the electronic components can be bent with the cooperation of the pressing block 8 and the rotating plate 172.

[0033] Working principle: When the device is in use, the staff first moves the two connecting rods 16 in opposite directions through the support mechanism 17. During this process, the staff can rotate the two rotating plates 172. At this time, the two support plates 173 are arranged relative to each other. Then, after the staff places the electronic components on the top of the storage plate 13, under the action of the elastic force of the fourth compression spring 153, the connecting rod 16 drives the two rotating plates 172 to move to the opposite sides. Accordingly, the electronic components can be clamped and supported by the cooperation of the rotating plates 172 and the support plates 173, so as to limit and fix their positions. Then the staff can The drive motor 61 can be started to adjust the distance between the two pressing blocks 8 so that the pressing blocks 8 can be better used in the processing of electronic components. The staff starts the electric push rod 31, and the lifting plate 32 drives the L-shaped plate 33 to descend. The cross plate 5 and the pressing block 8 descend at the same time. When the bottom of the positioning plate 93 contacts the top of the electronic component and the bottom of the pressing block 8 contacts the surface of the lead, the position of the electronic component is reinforced again, and the L-shaped plate 33 continues to drive the cross plate 5 to descend until the bottom of the storage plate 13 contacts the top of the buffer pad 19. During this process, the pressing block 8 continues to descend to bend the lead.
