Description

Technical Field

[0001] The present invention relates to the field of connector processing devices, and in particular to a pin bending device. Background Art

[0002] Connectors are also called plug-in parts, and are also called joints and sockets in China. They generally refer to electrical connectors, that is, devices that connect two active devices for transmitting current or signals; pin connectors are a type of connector, usually one of which contains multiple pins. The pins are generally rod structures, and the needle heads of the pins are used to plug into sockets, and the needle heads have cylindrical clamping columns similar to shaft shoulders, which are used to fix to the shell of the plug. The needle tails of the pins need to be bent 90 degrees and welded to the printed circuit board or signal connection line; the traditional bending method is to place the pins between two rollers, manually move one of the rollers to rotate around the other roller, and bend the pins. This bending method is labor-intensive and time-consuming, and inefficient, and because it is a manual operation, the bending accuracy cannot be guaranteed.

[0003] The present invention is proposed in view of the deficiencies in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a pin bending device.

[0005] The present invention can be achieved through the following technical solutions:

[0006] The cam is provided with a bottom plate, and the bottom plate is provided with a limit slide and a limit screw, and the limit slide is driven by the limit motor to rotate. The bottom plate is provided with a positioning plate, and a positioning plate is provided on the bottom plate. The positioning plate passes through the sliding plate and is threadedly connected to the sliding plate. The positioning plate passes through the sliding plate and is slidably connected to the sliding plate. A material tray is provided on the sliding plate, and a material trough is evenly provided on the material tray, and a slide groove penetrating the material tray on one side of the material trough is provided. An entry port is provided on the material tray on one side of the material trough. A limit slide and a limit screw are further provided above the bottom plate, and the limit screw is driven to rotate by the limit motor. The bottom plate is also provided with a slider above the bottom plate, The positioning motor drives the positioning screw to rotate a certain number of circles, and the next material trough on the material tray reaches the position opposite to the limit slot, and the connector pins are bent again, and the operation is cyclic. This device can automatically bend the connector pins and can bend multiple connector pins at a time, thereby greatly improving work efficiency.

[0007] Preferably, positioning posts are evenly fixed on the slide, and positioning holes are provided on the tray at positions corresponding to the positioning posts. By inserting the positioning posts into the positioning holes and placing the tray on the slide, the connector with the pins to be bent can be replaced.

[0008] Preferably, the base plate is further fixed with multiple cylinders, the piston rod ends of the cylinders are fixed to the mounting plate, and the limit plate and bending motor are both fixed to the mounting plate. When the connector pins are bent, the cylinders are activated, the piston rods on the cylinders are shortened, the limit plates move, and the distance between the limit plates and the positioning plate increases, and the connector with bent pins falls from the positioning plate and is collected.

[0009] Preferably, a support rod is fixed below the positioning plate, and the pin rotates around the support rod.

[0010] Compared with the existing technology, the present invention has the following advantages:

[0011] The device can automatically bend the pins of the connector and can perform bending operations on the pins of multiple connectors at one time, thereby greatly improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom of the material trough 8 is provided with a slide groove 9 that passes through the material tray 6, and an entry port 10 is provided on the material tray 6 on one side of the material trough 8. A limit slide 11 and a limit screw 12 are also provided above the base plate 1. The limit screw 12 is driven to rotate by the limit motor 13. A slider 14 is also provided above the base plate 1. The limit screw 12 passes through the slider 14 and is threadedly connected to the slider 14. The limit slide 11 passes through the slider 14 and is slidably connected to the slider 14. A push plate 15 is also fixed on the slider 14. A positioning plate 16 is also fixed on the base plate 1 on one side of the skateboard 5. A limit plate 19 is provided on one side of the positioning plate 16. The limit plate 19 and the positioning plate 16 form a limit groove 21. A bending motor 20 is also provided on one side of the limit plate 19. A turntable 22 is fixed to the output end of the bending motor 20, and a push rod 24 is also fixed on the turntable 22. The connectors with pins to be bent are evenly placed in each trough 8, and the pins of the connector pass through the slide 9. The positioning motor 4 drives the positioning screw 2 to rotate. When the positioning screw 2 turns to, the slide 5 moves on the positioning screw 2, and the material tray 6 moves with the slide 5. The first row of troughs 8 on the material tray 6 reaches the position opposite to the limit slot 21. The positioning motor 4 stops, the limit motor 13 starts, and the limit motor 13 drives the limit screw 12 to rotate. The slider 14 moves in the direction of the limit screw 12, and the push plate 15 moves with the slider 14. The bottom of the push plate 15 enters from the entrance 10 and pushes the connector in the slide 9 to move. After the connector in the slide groove 9 moves to the limit groove 21, the bending motor 20 drives the turntable 22 to rotate, and the push rod 24 contacts the pin and pushes the pin to bend. After the pin is bent, the bent connector is collected, and the push plate 15 returns to the initial position. The positioning motor 4 drives the positioning screw 2 to rotate a certain number of circles again.
