Description

Technical Field

[0001] The utility model relates to a bending device, in particular to a wire arrangement bending mechanism. Background Art

[0002] With the development of the times, industrial production technology is also developing rapidly, and automated equipment is increasingly used in industrial production. In order to adapt to the assembly of products with different shapes, the angle between the workpiece body and the wire arrangement needs to be adjusted before the workpiece assembly.

The bending end of the bending component can squeeze the front surface of the workpiece body. The pins connecting the workpiece body and the flexible cable can be bent under the squeeze of the bending component. During use, first place the workpiece component on the top of the bending seat 5, and then use the first linear moving mechanism 2 to lift the workpiece component to a suitable height to facilitate the pressing mechanism to fix the workpiece component. Then the bending component moves to the workpiece component under the drive of the second linear moving mechanism 3. The bending end of the bending component faces the front surface of the workpiece body. Then the pressing mechanism fixes the flexible cable. The moving end of the third linear moving mechanism 4 pushes the pushing end of the bending component. The bending end of the bending component approaches and squeezes the front surface of the workpiece body from the lower oblique side of the workpiece body under the drive of the third linear moving mechanism 4.

Since the whole process is fully automated, the automation degree is high. It has the advantage of high automation degree. In this embodiment, the X-axis is parallel to the ground and the Z-axis is perpendicular to the ground.

[0021] Optionally, in this embodiment, a fixing base 7 is provided at the top of the bending base 5. A fixing opening for placing the workpiece assembly 14 is formed at the top of the fixing base 7. A suction nozzle hole is formed in the bottom wall of the fixing opening. The suction nozzle is fixed in the suction nozzle hole.

The workpiece assembly 14 is pre-fixed by adsorbing the workpiece assembly 14 with the suction nozzle to prevent the workpiece assembly 14 from shaking during the process of the pressing mechanism fixing the wiring. After the pressing mechanism fixes the wiring, the suction nozzle stops adsorbing the workpiece assembly 14.

[0022] Optionally, in this embodiment, a photoelectric sensor capable of sensing the workpiece assembly 14 is further provided on the bottom wall of the fixing opening. When the photoelectric sensor detects the workpiece assembly 14, the suction nozzle starts to adsorb the workpiece assembly 14.

The buffer seats 12 are arranged oppositely at both ends of the limiting groove. A pressing rod 13 is threadedly connected to the buffer seat 12. The pushing block can drive the pushing plate 9 under the drive of the cylinder and drive the connecting seat 8 to approach the workpiece assembly 14. The buffer member 10 can abut against any one of the pressing rods 13. When bending is required, the pushing block drives the pushing plate 9 under the drive of the cylinder and drives the connecting seat 8 to approach the workpiece assembly 14. At this time, the end of the bending knife 11 presses the front of the workpiece body. Since the wiring is in a fixed state, the pins at the connection between the workpiece body and the wiring are stressed and bent, realizing the bending of the pins. When the buffer member 10 abuts against the pressing rod 13, the pressing rod 13 can block the buffer member 10 from continuing to move to play a limiting role.

[0026] Optionally, in this embodiment, the buffer member 10 is made of a flexible material, and the folding cutter 11 is made of an anti-static material.

The side of the fixing plate 6 away from the ground is defined as the top surface of the fixing plate 6. In this embodiment, the angle between the top surface of the fixing plate 6 and the ground is 45 degrees.
