[0016] The following is combined with the attached Figure 1-5 The present invention is further described in detail with reference to the accompanying drawings.

[0017] A VCM motor ground pin bending device, comprising a three-axis gantry manipulator 1, a connecting plate 2, a fixture fixing plate 3, a clamping cylinder 4, a motor clamping block 5, a bending adjustment strip 6, and a bending head 7;

[0018] The three-axis gantry manipulator 1 has a connecting plate 2 fixed on the Z axis, a fixture fixing plate 3 installed on the connecting plate 2, a clamping cylinder 4 and a bending adjustment strip 6 installed on the clamp fixing plate 3; the clamping cylinder 4 pushes out the top to install a motor clamping block 5; and a bending head 7 is fixed on the bending adjustment strip 6.

[0019] The three-axis gantry manipulator is a gantry-type structure, and the precision ball screw linear module of each axis is driven by a precision stepper motor; a product seat 11 is arranged on the Y axis of the three-axis gantry manipulator, and a plurality of grooves for accommodating products are arranged on the product seat.

[0020] A precision positioning strip protrusion 8 is processed on the fixture fixing plate 3; a long hole and multiple groups of threaded holes are processed on the left and right sides of the strip positioning protrusion 8 respectively; a clamping cylinder 4 is fixedly connected to the fixture fixing plate through the long hole, and a bending adjustment strip 6 is fixedly connected to the fixture fixing plate through multiple groups of threaded holes.

[0021] The clamping cylinder 4 is a slide cylinder with a guiding function, and a motor clamping block 5 is installed at the top end of the pushing-out part of the clamping cylinder 4.

[0022] The motor pressing block 5 is provided with a strip-shaped positioning surface 10 matched with the cylinder on the upper side, and a rectangular protrusion on the back side.

[0023] The bending adjustment strip 6 is an inverted T-shaped structure. A positioning concave surface is provided on the back of the bending adjustment strip 6 and is installed on the fixture fixing plate 3. A positioning convex surface 9 is provided on the other side of the bending adjustment strip 6. A fixed bending head 7 is installed on the positioning convex surface, and the positioning convex surface has more than two long holes on it to facilitate the adjustment of the height of the fixed bending head 7.

[0024] The bending head 7 is shaped like a finger-shaped structure, and there is an inclined surface 12 on the finger-shaped protrusion corresponding to the required bending angle.

[0025] like Figure 3 As shown, each axis of the three-axis gantry robot is driven by a high-precision preferred stepper motor with a high-speed and high-precision screw module. A product seat is provided on the Y-axis of the robot, and a plurality of grooves for accommodating products are provided on the product seat to ensure that multiple products can be processed simultaneously and improve the processing efficiency. A connecting plate is installed on the Z-axis of the gantry robot, and a fixture fixing plate is installed on the connecting plate.

[0026] like Figure 2 As shown, the clamp fixing plate is respectively installed with a clamping cylinder and a bending adjustment strip on the left and right sides, and the clamping cylinder and the bending adjustment strip are respectively tightly fitted with the left and right sides of the bar-shaped positioning protrusion on the clamp fixing plate to ensure the parallelism of the clamping cylinder and the bending adjustment strip. The positioning protrusion on the bending adjustment strip is positioned with the side of the bending head to ensure the parallelism of the bending strips. Figure 3 The strip positioning surface of the clamping block cooperates with the cylinder to ensure the parallelism between the cylinder and the clamping block; the above cooperation can ensure the parallelism between the clamping block and the bending head;

[0027] like Figure 4 As shown, during the bending process of the VCM motor ground pin, the Z axis slowly drops, the cylinder is in the push-out state, the clamping block first contacts the upper surface of the VCM, the cylinder gradually compresses to clamp the motor, and at the same time the bending head continues to descend, bending the ground pin through the finger-shaped protrusion;

[0028] like Figure 5 As shown, during the descent of the finger-shaped structure, the angle of the lower slope corresponds to the required bending angle of the grounding Pin, gradually contacting and deforming the grounding Pin until it is fully contacted. The slight Z-direction travel difference of this structure will not affect the Pin bending angle, thereby achieving the purpose of high bending accuracy.
