[0031] As Figure 1 、 Figure 2 And Figure 6 shown, the present invention provides an integrally formed lead frame positioning device, which includes an upper pressure 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 upper pressure plate 1 positions the coil to improve the accuracy and avoid product scrapping or abnormal alarm of the machine caused by the coil being placed unevenly. Specifically, square grooves 5 are evenly arranged at the top end of the lower template 2. The coil is placed in the square grooves 5, which can carry the coil and preliminarily limit the coil at the same time. Meanwhile, a square pressing ring 12 is installed at the bottom end of the upper pressure plate 1. The upper pressure plate 1 is located above the lower template 2, and the positions of the square pressing ring 12 and the square grooves 5 correspond. A main cylinder 14 is installed on the upper pressure plate 1. The upper pressure plate 1 is moved up and down relative to the lower template 2 through the main cylinder 14. When the upper pressure plate 1 moves down, the square pressing ring 12 is clamped into the square grooves 5, and the positioning of the coil is realized through the extrusion of the square pressing ring 12 and the square grooves 5. An electric slide rail 7 is installed at the bottom end 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 through the electric slide plate 8. After the electric slide rail 7 is powered on, the electric slide plate 8 moves linearly on the electric slide rail 7, and the upper pressure plate 1 is driven to move together through the main cylinder 14. When the electric slide plate 8 moves away from the lower template 2, the upper pressure plate 1 covering the upper part of the lower template 2 is moved away. At this time, the manipulator takes out the coil in the square grooves 5.

[0032] During operation, the manipulator takes out the coil from the lead frame and places it into the square grooves 5. The main cylinder 14 pulls down the upper pressure plate 1 to make the square pressing ring 12 slide into the square grooves 5 to squeeze and position the coil in the square grooves 5. Then, the main cylinder 14 pushes up the upper pressure plate 1, and the coil can be taken out from the lower template 2 and placed into the mold by the manipulator.

[0033] Embodiment 1

[0034] Circular grooves 4 are also evenly arranged at the top end of the lower template 2. Both the circular grooves 4 and the square grooves 5 are used for loading the coil. The square grooves 5 are used for positioning the linear coil, and the circular grooves 4 are used for positioning the annular coil. A circular pressing ring 11 is installed at the bottom end of the upper pressure plate 1, and 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 both the linear coil and the annular coil, expanding its application range.

[0035] Furthermore, in order to move away the upper pressure plate 1 covering the upper part of the lower template 2, the lower template 2 is installed on the frame, as Figure 7As shown in the figure, a servo motor is installed on the frame. The servo motor is located below the lower template 2 and 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, shortening the time for the manipulator to remove the coil from the lower template 2, thereby improving the processing efficiency.

[0036] Furthermore, a square groove 5 and a circular groove 4 are provided at the top end of the upper pressure plate 1. The positions of the square groove 5 and the circular groove 4 on the upper pressure plate 1 correspond to those on the lower template 2. In addition to assisting in positioning the coil in the lower template 2, the top end of the upper pressure plate 1 also bears the coil. When the upper pressure plate 1 moves downward to position the coil in the lower template 2, or when the upper pressure plate 1 rotates to one side, an external force can be used to position the coil in the upper pressure plate 1, enabling the upper pressure plate 1 and the lower template 2 to position multiple coils at one time, improving the efficiency.

[0037] Embodiment 2

[0038] On the basis of the above Embodiment 1, in order to make full use of the utilization rate of the upper pressure plate 1 and the lower template 2, the position of the circular pressing ring 11 is separately matched with the circular groove 4, and the square pressing ring 12 is separately matched with the square groove 5. Specifically, when positioning a linear coil, at this time, the circular groove 4 is in a blocked state, the circular pressing ring 11 is located in the upper pressure plate 1, and the bottom end of the circular pressing plate 11 is flush with the bottom end of the upper pressure plate 1. Conversely, when positioning an annular coil, the square groove 5 is in a blocked state, the square pressing ring 12 is located in the upper pressure plate 1, and the bottom end of the square pressing ring 12 is flush with the bottom end of the upper pressure plate 1.

[0039] As Figure 3 and Figure 4 shown, square through holes 108 and circular through holes 109 are evenly spaced in the upper pressure plate 1. The circular pressing ring 11 is movably installed in the circular through hole 109, and the square pressing ring 12 is movably installed in the square through hole 108. By driving with an external force, the square pressing ring 12 moves linearly along the square through hole 108, and the circular pressing ring 11 moves linearly along the circular through hole 109.

[0040] An inner cavity 105 is provided 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. The square through hole 108 and the circular through hole 109 are located below the intermediate pressure plate 106. The circular pressing ring 11 passes through the intermediate pressure plate 106, and a small pressure plate 107 is installed at the top end of the circular pressing ring 11. The small pressure plate 107 is located in the inner cavity 105. The square pressing ring 12 moves with the intermediate pressure plate 106, and the circular pressing ring 11 moves with the small pressure plate 107. Power structures are also installed at both ends of the inner cavity 105 to drive the intermediate pressure plate 106 and the small pressure plate 107 to move.

[0041] As Figure 3 and Figure 4As shown in the figure, the power structure includes a cylindrical power rod 104. One end of the cylindrical power rod 104 is installed on the turntable 103. The axis of the cylindrical power rod 104 and the axis of the turntable 103 are not on the same straight line. The other end of the cylindrical power rod 104 extends into the inner cavity 105. A fixed block 102 is installed outside the turntable 103. Motors 101 are installed at both ends of the upper pressure plate 1. A motor hole 116 is opened in the fixed block 102. The motor shafts of the motors 101 pass through the motor hole 116 and are connected to the turntable 103.

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

[0043] During operation, for the linear coil positioning: The manipulator takes the coil out of the lead frame and places it into the square groove 5. The motor 101 drives the turntable 103 to rotate counterclockwise by 180 degrees. Through the cylindrical power rod 104, the intermediate pressure plate 106 is pressed downward, so that the square pressure ring 12 slides out of the square through hole 108. The main cylinder 14 pulls the upper pressure plate 1 downward, so that the bottom of the square pressure ring 12 slides into the square groove 5 to squeeze and position the coil in the square groove 5. Then, the main cylinder 14 pushes the upper pressure plate 1 upward. The main cylinder 14 is driven by a servo motor to rotate, and the upper pressure plate 1 rotates 180 degrees relative to the lower template 2. Then, the coil is taken out of the lower template 2 by the manipulator and placed into the mold. For the annular coil positioning: The manipulator takes the coil out of the lead frame and places it into the circular groove 4. The motor 101 drives the turntable 103 to rotate clockwise by 90 degrees. Through the cylindrical power rod 104, the small pressure plate 107 is pressed downward, 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 bottom of the circular pressure ring 11 slides into the circular groove 4 to squeeze and position the coil in the circular groove 4. Then, the main cylinder 14 pushes the upper pressure plate 1 upward. The main cylinder 14 is driven by a servo motor to rotate, and the upper pressure plate 1 rotates 180 degrees relative to the lower template 2. Then, the coil is taken out of the lower template 2 by the manipulator and placed into the mold. The intermediate pressure plate 106 and the small pressure plate 107 are provided with a self-elastic structure (not shown in the figure). When the force applied by the cylindrical power rod 104 on the intermediate pressure plate 106 and the small pressure plate 107 disappears, the intermediate pressure plate 106 and the small pressure plate 107 automatically return to their original positions.

[0044] Embodiment 3

[0045] To further improve the stability of the cylindrical power rod 104 in driving the middle pressing plate 106 and the small pressing plate 107 downward, as Figure 4 shown, a clamping member 111 is installed inside the turntable 103. The clamping member 111 is in close contact with the cylindrical power rod 104, and the position of the Far East power rod 104 is locked by the clamping member 111 (at the position as Figure 4 shown). A groove 113 is formed in the fixing block 102, and an external magnetic attracting member 114 is slidably installed in the groove 113. Four external magnetic attracting members 114 are symmetrically installed on the fixing block 102. The external magnetic attracting member 114 and the cylindrical power rod 104 are on the same horizontal line. When the external magnetic attracting member 114 is electrified, the clamping member 111 loses power and stops working, causing the cylindrical power rod 104 to move towards the external magnetic attracting member 114 along the direction of the straight groove 112 and tightly adsorb on the external magnetic attracting member 114. A notch 110 is formed in the turntable 103, and an internal magnetic attracting member 115 is also installed in the groove 113. When the internal magnetic attracting member 115 is electrified, the external magnetic attracting member 115 attracts the cylindrical power rod 104 to move towards the internal magnetic attracting member 115 together. Through the cooperation of the external magnetic attracting member 114 and the internal magnetic attracting member 115, the cylindrical power rod 104 first moves horizontally and then vertically, accurately making the middle pressing plate 106 and the small pressing plate 107 move linearly, so as to ensure that the square pressing ring 12 and the circular pressing ring 11 accurately slide into the square groove 5 and the circular groove 4 respectively.

[0046] Its working principle is as follows: For the positioning of a linear coil, the manipulator takes the coil from the lead frame and places it into the square groove 5. The motor 101 drives the turntable 103 to rotate counterclockwise by 180°. When the outer magnetic attracting member 114 is electrified, the clamping member 111 loses power and does not work. The cylindrical power rod 104 moves along the direction of the straight groove 112 towards the outer magnetic attracting member 114 and tightly adsorbs on the outer magnetic attracting member 114. When the inner magnetic attracting member 115 is electrified, the outer magnetic attracting member 115 drives the cylindrical power rod 104 to be attracted towards the inner magnetic attracting member 115 together. The middle pressing plate 106 is pressed downwards through the cylindrical power rod 104, causing the square pressing ring 12 to slide out of the square through-hole 108. The main cylinder 14 pulls down the upper pressing plate 1, making the bottom of the square pressing ring 12 slide into the square groove 5 to squeeze and position the coil in the square groove 5. Then, the main cylinder 14 pushes the upper pressing plate 1 upwards, drives the main cylinder 14 to rotate through the servo motor, and the upper pressing plate 1 rotates 180 degrees relative to the lower template 2. Then, the coil is taken out from the lower template 2 by the manipulator and placed into the mold. For the positioning of an annular coil, the manipulator takes the coil from the lead frame and places it into the circular groove 4. The motor 101 drives the turntable 103 to rotate clockwise by 90 degrees. When the outer magnetic attracting member 114 is electrified, the clamping member 111 loses power and does not work. The cylindrical power rod 104 moves along the direction of the straight groove 112 towards the outer magnetic attracting member 114 and tightly adsorbs on the outer magnetic attracting member 114. When the inner magnetic attracting member 115 is electrified, the outer magnetic attracting member 115 drives the cylindrical power rod 104 to be attracted towards the inner magnetic attracting member 115 together. The small pressing plate 107 is pressed downwards through the cylindrical power rod 104, causing the circular pressing ring 11 to slide out of the circular through-hole 109. The main cylinder 14 pulls down the upper pressing plate 1, making the bottom of the circular pressing ring 11 slide into the circular groove 4 to squeeze and position the coil in the circular groove 4. Then, the main cylinder 14 pushes the upper pressing plate 1 upwards, drives the main cylinder 14 to rotate through the servo motor, and the upper pressing plate 1 rotates 180 degrees relative to the lower template 2. Then, the coil is taken out from the lower template 2 by the manipulator and placed into the mold. The middle pressing plate 106 and the small pressing plate 107 are provided with elastic structures (not shown in the figure) by themselves. When the force applied by the cylindrical power rod 104 on the middle pressing plate 106 and the small pressing plate 107 disappears, the middle pressing plate 106 and the small pressing plate 107 automatically return to their original positions.

[0047] Embodiment 4

[0048] To facilitate the manipulator to take out the coil in the lower template 2, such as Figure 5As shown in the figure, a movable plate 3 is slidably connected inside the lower template 2. A square ejector pin 301 is integrally welded on the movable plate 3. A jacking channel 201 is also opened inside the lower template 2. The square ejector pin 301 is located inside the jacking channel 201. A receiving cavity 302 is reserved inside the movable plate 3. An inner top plate 303 is slidably installed inside the receiving cavity 302. A circular ejector pin 304 is integrally welded on the inner top plate 303. The top end of the circular ejector pin 304 passes through the movable plate 3 and is located inside the jacking channel 201. The square ejector pin 301 is welded on the movable plate 3, and the circular ejector pin 304 is welded on the inner top plate 303. The inner top plate 303 moves relative to the movable plate 3, realizing the independent movement of the square ejector pin 301 and the circular ejector pin 304. That is, the square ejector pin 301 and the circular ejector pin 304 can not only jack up the coil, but also block the square groove 5 or the circular groove 4 when the square groove 5 or the circular groove 4 is not in use.

[0049] A top column 6 is installed at the bottom end of the inner top plate 303. A lower top plate 10 is installed at the bottom end of the top column 6. The top column 6 penetrates through the support plate 9. A lower concave hole 901 is opened on the support plate 9. The top of the lower top plate 10 is located inside the lower concave hole 901. A cylinder 13 is installed on the support plate 9. The cylinder 13 is connected to the movable plate 3. The up and down movement of the movable plate 3 is realized through the cylinder 13. A structure for driving the up and down movement of the lower top plate 10 (not shown in the figure) is installed on the frame.

[0050] The working principle of the present invention:

[0051] When using the square groove 5, the lower top plate 10 pushes the inner top plate 303 upward, so that the circular ejector pin 304 blocks the circular groove 4. The manipulator takes out the coil from the lead frame and places it into the square groove 5. The motor 101 drives the turntable 103 to rotate counterclockwise by 180°. When the outer magnetic attracting member 114 is electrified, the clamping member 111 loses power and does not work. The cylindrical power rod 104 moves along the direction of the straight groove 112 towards the outer magnetic attracting member 114 and tightly adsorbs on the outer magnetic attracting member 114. When the inner magnetic attracting member 115 is electrified, the outer magnetic attracting member 115 drives the cylindrical power rod 104 to suck together towards the inner magnetic attracting member 115. 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. The main cylinder 14 pulls the upper pressing plate 1 downward, 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, drives the main cylinder 14 to rotate through the servo motor, and the upper pressing plate 1 rotates 180 degrees relative to the lower template 2. Then, the coil is taken out from the lower template 2 by the manipulator and placed into the mold;

[0052] When using the circular groove 4, the air cylinder 13 pushes up the movable plate 3, so that the square ejector pin 301 blocks the square groove 5. The manipulator takes out the coil from the lead frame and places it into the circular groove 4. The motor 101 drives the turntable 103 to rotate clockwise by 90 degrees. When the outer magnetic attracting member 114 is electrified, the clamping member 111 loses power and does not work. The cylindrical power rod 104 moves along the direction of the straight groove 112 towards the outer magnetic attracting member 114 and tightly adsorbs on the outer magnetic attracting member 114. When the inner magnetic attracting member 115 is electrified, the outer magnetic attracting member 115 attracts the cylindrical power rod 104 to be attracted together towards the inner magnetic attracting member 115. The small pressing plate 107 is pressed down through the cylindrical power rod 104, so that the circular pressing ring 11 slides out of the circular through hole 109. The main air cylinder 14 pulls down the upper pressing plate 1, so that the bottom of the circular pressing ring 11 slides into the circular groove 4 to squeeze and position the coil in the circular groove 4. Then, the main air cylinder 14 pushes up the upper pressing plate 1, and drives the main air cylinder 14 to rotate through the servo motor. The upper pressing plate 1 rotates 180 degrees relative to the lower template 2. Then, the coil is taken out from the lower template 2 by the manipulator and placed into the mold. The intermediate pressing plate 106 and the small pressing plate 107 are provided with elastic structures (not shown in the figure) by themselves. When the force applied by the cylindrical power rod 104 on the intermediate pressing plate 106 and the small pressing plate 107 disappears, the intermediate pressing plate 106 and the small pressing plate 107 automatically return to their original positions.
