[0031] like Figure 1 , Figure 2 and Figure 6 As shown, the present invention provides an integrated lead frame positioning device, including an upper pressing plate 1 and a lower template 2, the lower template 2 is used to carry the coil, the coil is directly taken from the lead frame and placed on the lower template 2 by a manipulator, the coil is positioned by the upper pressing plate 1, the accuracy is improved, and the product scrapping or machine abnormality alarm is avoided due to the deviation of the coil. Specifically, square grooves 5 are evenly arranged on the top of the lower template 2, the coil is placed in the square grooves 5, and the coil can be initially limited while carrying the coil. At the same time, a square pressing ring 12 is installed at the bottom end of the upper pressing plate 1, the upper pressing plate 1 is located above the lower template 2, the positions of the square pressing ring 12 and the square groove 5 correspond, and the upper pressing plate 1 is installed There is a main cylinder 14, which is used to move the upper pressure plate 1 up and down relative to the lower template 2. When the upper pressure plate 1 moves down, the square pressure ring 12 is inserted into the square groove 5, and the coil is positioned by squeezing the square pressure ring 12 and the square groove 5. An electric slide rail 7 is installed at the bottom of the lower template 2, and an electric slide plate 8 is slidably connected to the electric slide rail 7. The main cylinder 14 penetrates the electric slide rail 8. After the electric slide rail 7 is energized, the electric slide plate 8 moves in a straight line on the electric slide rail 7, and the upper pressure plate 1 is driven to move together by the main cylinder 14. When the electric slide plate 8 moves in a direction away from the lower template 2, the upper pressure plate 1 covering the upper part of the lower template 2 is removed. At this time, the manipulator takes out the coil in the square groove 5.

[0032] During operation, the manipulator takes the coil out of the wire rack and places it in the square groove 5. The main cylinder 14 pulls down the upper pressing plate 1 to make the square pressing ring 12 slide into the square groove 5, and squeezes and positions the coil in the square groove 5. Then, the main cylinder 14 pushes up the upper pressing plate 1, and the manipulator can take the coil out of the lower template 2 and place it in the mold.

[0033] Embodiment 1

[0034] Circular grooves 4 are evenly distributed on the top of the lower template 2. The circular grooves 4 and the square grooves 5 are both used for loading coils. The square grooves 5 are used to position linear coils, and the circular grooves 4 are used to position ring-shaped coils. A circular pressing ring 11 is installed on the bottom end of the upper pressing plate 1. The position of the circular pressing ring 11 corresponds to the position of the circular grooves 4, so that the lower template 2 can limit the linear coils and position the ring-shaped coils, thereby expanding its scope of application.

[0035] Further, in order to remove the upper pressing plate 1 covering the lower template 2, the lower template 2 is installed on the frame, such as Figure 7As shown, a servo motor is installed on the frame, and the servo motor is located below the lower template 2. The servo motor is connected to the bottom end of the main cylinder 14. The main cylinder 14 is driven to rotate by the servo motor, and the upper pressure plate 1 rotates relative to the lower template 2, thereby shortening the time for the robot to remove the coil in the template 2, thereby improving the processing efficiency.

[0036] Furthermore, a square groove 5 and a circular groove 4 are provided on the top of the upper pressing plate 1, and the positions of the square groove 5 and the circular groove 4 on the upper pressing plate 1 and the lower template 2 correspond. In addition to assisting in the positioning of the coil in the lower template 2, the upper pressing plate 1 also carries a coil on its top. When the upper pressing plate 1 moves downward to position the coil in the lower template 2, or when the upper pressing plate 1 is rotated to one side, external force can be used to position the coil in the upper pressing plate 1, so that the upper pressing plate 1 and the lower template 2 can position multiple coils at a time, thereby improving efficiency.

[0037] Embodiment 2

[0038] On the basis of the above-mentioned embodiment one, in order to make full use of the usage rate of the upper pressure plate 1 and the lower template 2, the position of the circular pressure ring 11 and the circular groove 4, the square pressure ring 12 and the square groove 5 are individually coordinated. Specifically, when positioning the linear coil, at this time, the circular groove 4 is in a blocked state, the circular pressure ring 11 is located in the upper pressure plate 1, and the bottom end of the circular pressure plate 11 is flush with the bottom end of the upper pressure plate 1. Conversely, when positioning the annular coil, the square groove 5 is in a blocked state, the square pressure ring 12 is located in the upper pressure plate 1, and the bottom end of the square pressure ring 12 is flush with the bottom end of the upper pressure plate 1.

The square pressure ring 12 is driven by external force to move linearly along the square through hole 108, and the circular pressure ring 11 is driven linearly along the circular through hole 109.

[0040] An inner cavity 105 is opened in the upper pressure plate 1, and an external force drive is installed in the inner cavity 105. Specifically, an intermediate pressure plate 106 is movably installed in the inner cavity 105, a square through hole 108 and a circular through hole 109 are located below the intermediate pressure plate 106, a circular pressure ring 11 passes through the intermediate pressure plate 106, and a small pressure plate 107 is installed on the top of the circular pressure ring 11, the small pressure plate 107 is located in the inner cavity 105, the square pressure ring 12 moves with the intermediate pressure plate 106, and the circular pressure ring 11 moves with the small pressure plate 107, and power structures are also installed at both ends of the inner cavity 105, and the power structure drives the intermediate pressure plate 106 and the small pressure plate 107 to move.

[0042] Specifically, the top ends of the middle pressing plate 106 and the small pressing plate 107 in the initial state are on the same horizontal plane. Figure 3 As shown, the cylindrical power rod 104 is located at the upper part of the turntable 103. When the motor 101 drives the turntable 103 to rotate 180 degrees counterclockwise, the cylindrical power rod 104 is located at the lower part of the turntable 103. When the turntable 103 rotates 180 degrees counterclockwise, it drives the middle pressure plate 106 to move downward, that is, the square pressure ring 12 slides out of the square through hole 108. Conversely, when the turntable 103 rotates 90 degrees clockwise, it drives the small pressure plate 107 to move downward. At this time, the depth of the circular groove 4 is half the depth of the square groove 5.

[0043] During operation, to position the linear coil: the manipulator takes the coil out of the wire rack and places it in the square slot 5, the motor 101 drives the turntable 103 to rotate 180 degrees counterclockwise, and presses the middle pressing plate 106 downward through the cylindrical power rod 104, so that the square pressing ring 12 slides out of the square through hole 108, and the main cylinder 14 pulls down the upper pressing plate 1, so that the bottom of the square pressing ring 12 slides into the square slot 5, and the coil in the square slot 5 is squeezed and positioned, and then the main cylinder 14 pushes the upper pressing plate 1 upward, and the servo motor drives the main cylinder 14 to rotate, and the upper pressing plate 1 rotates 180 degrees relative to the lower template 2, and then the manipulator takes the coil out of the lower template 2 and puts it into the mold; to position the ring-shaped coil: the manipulator takes the coil out of the wire rack and places it in the circular slot 4, and the motor 101 drives the turntable 103 to rotate 180 degrees counterclockwise, and the middle pressing plate 106 is pressed downward through the cylindrical power rod 104, so that the square pressing ring 12 slides out of the square through hole 108, and the main cylinder 14 pulls down the upper pressing plate 1, so that the bottom of the square pressing ring 12 slides into the square slot 5, and the coil in the square slot 5 is squeezed and positioned, and then the main cylinder 14 pushes the upper pressing plate 1 upward, and the servo motor drives the main cylinder 14 to rotate, and the upper pressing plate 1 rotates 180 degrees relative to the lower template 2, and then the manipulator takes the coil out of the lower template 2 and places it in the mold; The movable turntable 103 rotates 90 degrees clockwise, and the small pressure plate 107 is pressed downward by the cylindrical power rod 104, so that the circular pressure ring 11 slides out of the circular through hole 109, and the main cylinder 14 pulls down the upper pressure plate 1, so that the bottom of the circular pressure ring 11 slides into the circular groove 4, and the coil in the circular groove 4 is squeezed and positioned. Then, the main cylinder 14 pushes the upper pressure plate 1 upward, and the main cylinder 14 is driven to rotate by the servo motor. The upper pressure plate 1 rotates 180 degrees relative to the lower template 2, and then the coil is taken out of the lower template 2 and placed in the mold by the manipulator. The middle pressure plate 106 and the small pressure plate 107 have their own elastic structure (not shown in the figure). When the force applied by the cylindrical power rod 104 to the middle pressure plate 106 and the small pressure plate 107 disappears, the middle pressure plate 106 and the small pressure plate 107 automatically return to their original positions.

[0044] Embodiment 3

[0045] In order to further achieve the stability of the cylindrical power rod 104 driving the middle pressing plate 106 and the small pressing plate 107 to move downward, as shown in FIG. Figure 4 As shown, a clamping member 111 is installed in the rotating disk 103, and the clamping member 111 and the cylindrical power rod 104 are tightly fitted, and the position of the Far East power rod 104 is locked by the clamping member 111 (such as Figure 4 The fixing block 102 is provided with a groove 113, in which an external magnetic member 114 is slidably installed, and four external magnetic members 114 are symmetrically installed on the fixing block 102. The external magnetic members 114 and the cylindrical power rod 104 are on a horizontal line. When the external magnetic members 114 are energized, the clamping member 111 loses power and does not work, so that the cylindrical power rod 104 moves toward the external magnetic member 114 along the direction of the straight groove 112 and is tightly adsorbed on the external magnetic member 114. There is a notch 110, and an inner magnetic component 115 is installed in the groove 113. When the inner magnetic component 115 is energized, the outer magnetic component 115 brings the cylindrical power rod 104 toward the inner magnetic component 115. Through the cooperation of the outer magnetic component 114 and the inner magnetic component 115, the cylindrical power rod 104 is moved horizontally and then vertically, and the middle pressure plate 106 and the small pressure plate 107 are accurately moved in a straight line, thereby ensuring that the square pressure ring 12 and the circular pressure ring 11 accurately slide into the square groove 5 and the circular groove 4 respectively.

[0046] The working principle is as follows: the linear coil is positioned, the manipulator takes the coil out of the wire rack and places it in the square slot 5, the motor 101 drives the turntable 103 to rotate 180 degrees counterclockwise, when the outer magnetic member 114 is energized, the clamping member 111 loses power and does not work, the cylindrical power rod 104 moves toward the outer magnetic member 114 along the direction of the straight slot 112, and is tightly adsorbed on the outer magnetic member 114, when the inner magnetic member 115 is energized, the outer magnetic member 115 brings the cylindrical power rod 104 together with the inner magnetic member 115, and the middle pressure is pressed by the cylindrical power rod 104. The plate 106 is pressed downward, so that the square pressing ring 12 slides out of the square through hole 108, and the main cylinder 14 pulls down the upper pressing plate 1, so that the bottom of the square pressing ring 12 slides into the square groove 5, and the coil in the square groove 5 is squeezed and positioned. Then, the main cylinder 14 pushes the upper pressing plate 1 upward, and the main cylinder 14 is driven to rotate by the servo motor. The upper pressing plate 1 rotates 180 degrees relative to the lower template 2, and then the coil is taken out from the lower template 2 and placed in the mold by the manipulator; to position the ring-shaped coil, the manipulator takes the coil out of the wire rack and places it in the circular groove 4, and the motor 101 The drive turntable 103 rotates 90 degrees clockwise. When the outer magnetic member 114 is energized, the clamping member 111 loses power and does not work. The cylindrical power rod 104 moves toward the outer magnetic member 114 along the direction of the straight groove 112 and is tightly adsorbed on the outer magnetic member 114. When the inner magnetic member 115 is energized, the outer magnetic member 115 brings the cylindrical power rod 104 together with the inner magnetic member 115, and the small pressure plate 107 is pressed downward by the cylindrical power rod 104, so that the circular pressure ring 11 slides out of the circular through hole 109. The main cylinder 14 pulls the upper pressure plate 1 downward, so that the circular pressure ring 11 slides into the circular groove 4 at the bottom to squeeze and position the coil in the circular groove 4, and then the main cylinder 14 pushes the upper platen 1 upward, and the main cylinder 14 is driven to rotate by the servo motor, and the upper platen 1 rotates 180 degrees relative to the lower template 2, and then the coil is taken out from the lower template 2 and placed in the mold by the manipulator. The middle platen 106 and the small platen 107 have their own elastic structure (not shown in the figure). When the force applied by the cylindrical power rod 104 to the middle platen 106 and the small platen 107 disappears, the middle platen 106 and the small platen 107 automatically return to their original positions.

Then, the main cylinder 14 pushes the upper pressing plate 1 upward, and the main cylinder 14 is driven to rotate by the servo motor. The upper pressing plate 1 rotates 180 degrees relative to the lower template 2, and then the coil is taken out from the lower template 2 and placed in the mold by the manipulator;
