Technical Field

For example, a pin inserter is used to insert the pins of a pin header into a plastic body, then a riveting machine is used to rivet the pins of the pin header into the plastic body, and then a bending machine is used to bend and form the pins of the pin header, and finally the production of the connector is completed.

[0003] The bending of the pins of a pin header is generally carried out by a pin bending device. For example, the pin bending tool disclosed in the patent document with the publication number CN219335739U is provided with a fixed plate, a movable plate and an adjustment seat. The fixed plate is fixedly arranged at one end of the adjustment seat, the movable plate is arranged opposite to the fixed plate, the adjustment seat is provided with a first sliding groove, and the distance between the movable plate and the fixed plate can be adjusted by sliding the movable plate along the first sliding groove, and then fixed on the adjustment seat by means of a locking bolt.

[0032] The preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, rather than to limit the scope of the present invention.

[0033] An embodiment of the present invention provides a pin bending device for bending the pins of electronic components. Without reversing the components, the pins on both sides of the electronic components can be bent in different directions, solving the technical problem that in the prior art, when the pin bending device bends the pins in two different directions, the components need to be reversed, resulting in a reduction in the bending efficiency of the pins.

[0034] To achieve the above technical objectives, the pin bending device provided by the embodiment of the present invention is as Figures 1-3 shown, including a mounting frame 10, a swing frame 20, a driving unit 30, and a bending member 40. The swing frame 20 is connected to the mounting frame 10; the driving unit 30 is connected to the swing frame 20 and is used to drive the swing frame 20 to swing reciprocally; the bending member 40 is fixed to the swing frame 20, and the tip of the bending member 40 can extend between two rows of pins. On both sides of the tip of the bending member 40, a first bending surface 41 and a second bending surface 42 are respectively formed. The first bending surface 41 can bend one row of pins through the swing of the swing frame 20 towards the side of the first bending surface 41, and the second bending surface 42 can bend the other row of pins through the swing of the swing frame 20 towards the side of the second bending surface 42.

[0035] Specifically, by providing the mounting frame 10, the swing frame 20, the driving unit 30, and the bending member 40, the pin bending device can be fixed on the frame of the pin bending equipment through the mounting frame 10. The swing frame 20 is connected to the mounting frame 10, and the driving unit 30 is connected to the swing frame 20 and can drive the swing frame 20 to swing reciprocally along the mounting frame 10. The bending member 40 is fixed to the swing frame 20. When the swing frame 20 swings, it can drive the bending member 40 to swing reciprocally. Through the above structure, when performing the pin bending operation, the tip of the bending member 40 is located between two rows of pins to be bent of the electronic component. On both sides of the tip of the bending member 40, a first bending surface 41 and a second bending surface 42 are respectively formed. The driving unit 30 drives the swing frame 20 to swing towards the side of the first bending surface 41, and then the bending member 40 drives one row of pins towards the swinging direction through the first bending surface 41 to bend them. After the pins on this side are bent, the driving unit 30 drives the swing frame 20 to swing towards the side of the second bending surface 42, and then the bending member 40 drives the other row of pins towards the swinging direction through the second bending surface 42 to bend them. Through the above structure, without manipulating the components to be reversed, the automatic bending of the row of pins on both sides of the component in different directions can be realized, effectively improving the bending efficiency of the row of pins of the component.

[0036] It is understandable that the mounting frame 10 can be any frame structure that can be fixed on the rack of the bending device.

[0037] In this embodiment, as Figure 1 shown, a mounting plate 11 is provided at the end of the mounting frame 10, and the mounting frame 10 can be fixed to the rack of the bending device through the mounting plate 11.

[0038] It is understandable that the swing frame 20 can be connected to the mounting frame 10 in a structural form such as hinged connection or sliding connection, which can realize reciprocating swing around the mounting frame 10.

[0039] In one of the embodiments, as Figure 1 shown, the mounting frame 10 is provided with an arc-shaped sliding groove 12, and the swing frame 20 is slidably connected to the arc-shaped sliding groove 12. The driving unit 30 is used to drive the swing frame 20 to slide reciprocally along the arc-shaped sliding groove 12. Specifically, by driving the swing frame 20 to slide reciprocally along the arc-shaped sliding groove 12, the driving unit 30 can realize reciprocating swing in both directions.

[0040] In one of the embodiments, as Figure 1 shown, a rotating cavity 13 is provided inside the mounting frame 10. The arc-shaped sliding groove 12 is located on both sides of the mounting frame 10 and communicates with the rotating cavity 13. The swing frame 20 is located in the rotating cavity 13. Specifically, the rotating cavity 13 can accommodate the swing frame 20, and the two arc-shaped sliding grooves 12 on both sides can ensure the stable sliding of the swing frame 20 along the mounting frame 10.

[0041] In one of the embodiments, as Figures 1-3 shown, sliding pulleys 21 are provided on both sides of the swing frame 20, and the sliding pulleys 21 are located in the arc-shaped sliding groove 12. Specifically, the sliding pulleys 21 can facilitate the sliding of the swing frame 20 along the sliding groove, and further facilitate the driving of the swing frame 20 by the driving unit 30.

[0042] In this embodiment, as Figures 1-3 shown, to improve the stability of the swing frame 20, the number of sliding pulleys 21 on each side of the swing frame 20 is two.

[0043] In one of the embodiments, as Figure 1 shown, the driving unit 30 includes a driving cylinder 31. One end of the driving cylinder 31 is hinged to the mounting frame 10, and the other end of the driving cylinder 31 is hinged to the swing frame 20. Specifically, through the driving force exerted by the driving end of the driving cylinder 31 on the swing frame 20, the driving frame can be driven to slide along the arc-shaped sliding groove 12, so that the driving cylinder 31 can drive the swing frame 20 to reciprocate by the telescopic movement of the driving end, thereby realizing the bending of the two side leads in different directions by the first bending surface 41 and the second bending surface 42 respectively.

[0044] In this embodiment, the driving cylinder 31 is a pneumatic cylinder.

[0045] In one of the embodiments, as Figures 1-3 shown, the swing frame 20 includes a driving block 22 and two sliding blocks 23. The two sliding blocks 23 are slidably connected to the arc-shaped feeding chute 12. The driving block 22 is fixed to the two sliding blocks 23 and extends in the direction of the driving cylinder 31. The driving cylinder 31 is connected to the driving block 22. Specifically, the sliding block 23 can facilitate the sliding of the swing frame 20 along the arc-shaped feeding chute 12. The driving block 22 can facilitate the connection between the driving cylinder 31 and the swing frame 20 and provide convenience for driving the swing frame 20.

[0046] In one of the embodiments, as Figures 1-2 shown, a plurality of first limiting grooves 411 are arranged at intervals on the first bending surface 41. Each of the first limiting grooves 411 is respectively used to accommodate each pin close to the first bending surface 41. Specifically, when bending the pins close to the first bending surface 41, each pin enters each of the first limiting grooves 411 respectively and is limited by the first limiting grooves 411, so as to avoid pin offset and ensure the bending quality of the pins.

[0047] In one of the embodiments, as Figure 1 and 3 shown, a plurality of second limiting grooves 421 are arranged at intervals on the second bending surface 42. Each of the second limiting grooves 421 is respectively used to accommodate each pin close to the second bending surface 42. Specifically, when bending the pins close to the second bending surface 42, each pin enters each of the second limiting grooves 421 respectively and is limited by the second limiting grooves 421, so as to avoid pin offset and ensure the bending quality of the pins.

[0048] In one of the embodiments, as Figures 1-3 shown, the bending member 40 includes a fixing block 43 and a bending block 44. The fixing block 43 is fixed to the swing frame 20. The bending block 44 is detachably fixed to the fixing block 43. The first bending surface 41 and the second bending surface 42 are both arranged on the bending block 44. Specifically, the fixing block 43 can realize the fixing of the bending member 40 and the swing frame 20. The bending block 44 can realize the bending of the pins. The detachable fixing of the bending block 44 to the fixing block 43 enables only different bending blocks 44 to be replaced to adapt to the bending of pins of different types of electronic components, thereby improving the practical performance of the bending device.

[0049] In one of the embodiments, as Figures 1-3As shown, the pin bending device further includes a supply slide rail 50. The supply slide rail 50 is located below the bending member 40. The supply slide rail 50 is provided with a supply slide cavity 51 for the sliding of electronic components. Specifically, the electronic components to be processed can move to the lower side of the bending member 40 by sliding along the supply slide cavity 51 in the supply slide rail 50. The pins of the electronic components extend out of the supply slide cavity 51, and through the limitation of the supply slide rail 50 and the cooperation with the bending member 40, the bending of the pins of the electronic components is realized.

[0050] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
