When the electronic components are inserted into the PCB circuit board, due to the vibration of the plug-in machine or the PCB circuit board, it is easy to cause the inserted electronic components to jump on the PCB circuit board. In order to prevent the electronic components from jumping out of the PCB circuit board, The pins of electronic components need to be bent, but the existing bending and shaping devices can only bend the pins of electronic components inserted horizontally or vertically, and cannot bend the pins of electronic components inserted in other angles. The pins are bent and shaped. If the installation position of the existing bending and shaping device is adjusted, the processing efficiency of the plug-in machine will be seriously affected, and the labor cost will be increased. The defects are obvious.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

As shown in Figures 1 to 4, Embodiment 1 of the all-round electronic component bender of the present invention includes a base 1 and a positioning sleeve 2 arranged on the base 1, the positioning sleeve 2 is provided with a through hole 3, and the through hole 3 The inner movable suit is provided with a curved foot body 4, and the upper end of the curved foot body 4 is provided with a concave curved surface groove 5 depressed inward; the base 1 is equipped with a driving device for driving the curved foot body 4 to move up and down.

See Fig. 3 and Fig. 4, in the plug-in processing process, the electronic component bender of described plug-in machine is positioned at the bottom of PCB circuit board, when plug-in machine inserts electronic component 13 on PCB circuit board, bends body 4 Under the action of the driving device, it moves upward until the upper end surface of the curved body 4 abuts against the bottom surface of the PCB circuit board. After the pins of the electronic components 13 pass through the PCB circuit board, the lower ends of the pins follow the groove 5 of the concave curved surface. The inner wall slides and bends to realize the bending function of the pin.

The all-round electronic component bender of the present invention not only has simple structure and low cost, but also has high bending stability, and can bend the pins of electronic components 13 at any insertion angle without cornering The limitation of the insertion angle can also be used to support the PCB circuit board during the plug-in processing, avoiding the bending deformation of the PCB circuit board due to extrusion, reducing the damage of the PCB circuit board, and improving the plug-in processing quality of the plug-in equipment.

The upper end of the curved foot body 4 of the present embodiment is provided with a boss 6, the cross-sectional area of the boss 6 is smaller than the cross-sectional area of the curved foot body 4, and the concave curved surface groove 5 is opened on the bottom of the boss 6 The upper surface; when the bending foot is processed, the bending foot body 4 is prevented from colliding with other electronic components on the PCB circuit board to cause damage to other electronic components, and the practicability is stronger.

The preferred method is that the concave curved surface groove 5 is spherical, and when the pins of the electronic components 13 are bent, the lower ends of the pins slide and bend along the spherical inner wall, regardless of where the inserted electronic components 13 are located. Any position can realize the bending function of the all-round electronic component bending device. Of course, the concave curved surface groove 5 can also be an irregular curved surface similar to a spherical shape, which can also achieve the above technical effects.

The driving device in this embodiment includes a pressure cylinder 7 installed on the base 1 and a piston rod 8 installed on the pressure cylinder 7 , and the piston rod 8 is connected to the bent body 4 .

A preferred embodiment is that the pressure cylinder 7 is an air cylinder. Under the control of air pressure, the piston rod 8 of the pressure cylinder 7 is extended or retracted, thereby realizing the function of the driving device controlling the upward and downward movement of the bending body 4, which has the advantages of simple structure, low cost, quick response and convenient maintenance Etc. Of course, the pressure cylinder 7 can also be a hydraulic cylinder, which uses hydraulic drive to control the piston rod 8 to extend or retract, which can also achieve the above technical effects.

Of course, the drive device can also be a rack and pinion and equipped with a servo motor to control the up and down movement of the bending body 4, without the need for air pressure supply equipment or hydraulic supply equipment, further reducing the input cost of plug-in equipment.

As shown in Figure 5, the second embodiment of the all-round electronic component bender of the present invention is different from the first embodiment above in that: the lower end of the bender body 4 is equipped with a connector 9, the connector 9 includes a screw rod 10, which is threadedly connected with the lower end of the bent body 4; the upper end of the piston rod 8 abuts against the lower end of the connector 9; the screw rod 10 is sleeved with a spring 11, and one end of the spring 11 is connected The lower end of the positioning sleeve 2 abuts, and the other end of the spring 11 is connected with the lower end of the screw rod 10 .

Because the structure and thickness of different PCB circuit boards and the structure of electronic components 13 are all different, thereby causing the distance between the upper end of the boss 6 and the lower surface of the PCB circuit board to be different, when changing different circuit boards or electronic After the element 13, it is only necessary to rotate the connecting head 9 to adjust the distance between the upper end of the boss 6 and the lower end of the connecting head 9 to the set length to meet the adjustment requirement. The adjustment work is simple and fast, and the practicability is strong.

In addition, during the assembly process of the omni-directional electronic component bender, if the coaxiality between the bend body 4 and the piston rod 8 is not high, it is easy to cause pressure when the bend body 4 moves up and down. The cylinder 7 and the piston rod 8 are stuck, seriously affecting the normal production of the plug-in equipment; If the coaxiality between the bending body 4 and the piston rod 8 is not high, the upper end of the piston rod 8 can automatically shift to a suitable position on the lower end surface of the connector 9, thereby effectively avoiding the The coaxiality problem causes the pressure cylinder 7 and the piston rod 8 to be stuck. When the piston rod 8 moves upward, the piston rod 8 pushes the bent body 4 to move upward synchronously, and when the piston rod 8 moves downward, the bent body 4 pushes the connecting head under the action of the spring 11 9 moves downwards, and drives the bent body 4 to move downwards, thereby realizing its driving function.

5, further, the screw 10 is connected with a fastening nut 12, the fastening nut 12 abuts against the lower end of the bent body 4, when the distance between the upper end of the boss 6 and the lower end of the connector 9 is adjusted After reaching the set length, turn the fastening nut 12 so that it closely abuts against the lower end of the bent body 4, preventing the connection between the connector 9 and the lower end of the bent body 4 from loosening and causing the quality of the bent foot to decline, improving the The bending quantity and performance stability of the all-round electronic component bending device of the present invention are guaranteed.

The above-mentioned embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be realized in other ways, and any obvious replacements are within the protection scope of the present invention without departing from the concept of the present invention.
