Description

Technical Field

[0001] This invention relates to a clamping device, and more particularly to an inductor coil clamping device. Background Technology

[0002] As an important component of electronic components, inductors must undergo multiple clamping operations during production and processing. To improve efficiency, clamping fixtures that simultaneously clamp multiple sets of components have been developed. However, traditional clamping devices usually require multiple independent cylinders, springs, or electric devices to drive each gripper. Although high-precision control can be achieved, problems such as complex drive structures, large size, and high cost exist. As shown in the patent for a gripper mechanism for an inductor (publication number CN201821611340.8), especially when multiple sets of grippers work together, if each set of grippers requires a separate drive system, it will greatly increase the complexity of the system and the difficulty of maintenance. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention aims to provide an inductor coil clamping device that requires only one drive unit to clamp multiple products under a certain air pressure. Since multiple products are clamped under the same air pressure, the air pressure inside the piston chamber is identical, thereby ensuring a high consistency in clamping effect. Even when clamping products of different models and sizes simultaneously, the pressure applied to the products is identical due to the same air pressure. This identical pressure also reduces the probability of mechanical damage to the inductor coil during clamping.

[0004] This invention provides the following technical solution:

[0005] An inductor coil clamping device includes a tooling base plate, a tooling mounting plate, and a pneumatic chamber located between the tooling base plate and the tooling mounting plate. The tooling mounting plate is installed on the drive end of a handling robot, allowing the handling robot to move the entire clamping device by driving it through the tooling mounting plate. The pneumatic chamber is filled with pressurized gas, which is usually injected into the pneumatic chamber under high pressure, thus generating a certain pressure within the chamber. Multiple clamping stations are evenly arranged circumferentially on the tooling base plate. Each clamping station is equipped with a clamping assembly. The clamping assembly includes multiple gripper units mounted on the tooling base plate for clamping and positioning the inductor coil. The gripper units are connected to the pneumatic chamber via connectors. A drive unit is also installed on the tooling base plate. The drive unit simultaneously drives multiple connectors to rotate synchronously, thereby causing the gripper units in each clamping assembly to perform clamping or releasing actions to complete the synchronous clamping or unloading operation of the product below each clamping station.

[0006] Thus, the inductor coil clamping device of the present invention only requires one drive unit to complete the synchronous clamping of multiple products. Since multiple products are clamped under the same air pressure, the air pressure in the piston chamber can be kept the same, thereby ensuring a high consistency of clamping effect. Even when clamping products of different models and sizes simultaneously, the pressure applied to the products can be kept the same due to the same air pressure. The same pressure can also reduce the probability of mechanical damage to the inductor coil during clamping. Furthermore, the air pressure in the air chamber can be adjusted by gas purging at any time according to the consumption, and the adjustment is also relatively convenient.

[0007] Preferably, each clamping assembly includes four sets of gripper units arranged in a cross shape. The inner sides of each pair of gripper units are provided with limiting groove cavities whose shape is adapted to the inductor coil. The gripper units are elastic grippers, which are used to further reduce the local pressure on the surface of the inductor coil during clamping.

[0008] Preferably, the gripper unit is connected to a set of piston rods via a connecting block. One end of the piston rod is positioned in a spring cavity, and the other end is positioned in a piston cavity. The connecting member is flexibly mounted on the tooling base plate and is connected to the pneumatic chamber via a rotary joint. When the connecting member is driven to rotate by the drive unit to communicate with the piston cavity, the gas in the pneumatic chamber is pressed into the piston cavity to achieve the clamping action of the gripper unit. When the pressure in the piston cavity is released, the spring in the spring cavity is used to release the gripper unit by pressing the piston block.

[0009] Preferably, the connector includes an inner cavity located in the inner layer and an outer cavity located in the outer layer. The inner cavity has a connecting pipe that passes through the outer cavity to connect to the piston cavity and a connecting pipe that connects to the rotary joint. When the connector rotates, so that the connecting pipe connects to the piston cavity, the gas in the pressure chamber enters the piston cavity through the connecting pipe and the connecting pipe to drive the piston block in the piston cavity to move, so as to realize the clamping action of the gripper unit.

[0010] Preferably, the outer cavity is provided with a pressure relief hole and a pressure relief groove. The connector is transferred and installed in the mounting groove of the tooling base plate, and there is a gap between the mounting groove and the outer cavity for the pressure relief groove to release air. The piston cavity is also provided with sealing blocks on both sides for abutting against the outside of the outer cavity. When the piston cavity is pressed, the connecting pipe is connected to the piston cavity and the pressure relief hole abuts against the sealing block. When the piston cavity is depressurized, the connector is rotated so that the connecting pipe abuts against the sealing block and the pressure relief hole is connected to the piston cavity. Then the air pressure in the piston cavity enters the outer cavity through the pressure relief hole and is then discharged through the pressure relief groove.

[0011] Preferably, an external gear ring is fixed to the outside of the two connecting tubes, and each clamping assembly also includes an internal gear ring that is transferred and mounted on the tooling base plate and meshes internally with multiple sets of external gear rings of the clamping assembly. The driving unit includes a drive motor mounted at the center of the tooling mounting plate. A set of meshing gears is fixed to the drive shaft of the drive motor. The meshing gears are located at the center of multiple sets of internal gear rings and mesh externally with the internal gear rings. In this way, synchronous clamping and releasing operations at different clamping positions on the tooling base plate can be achieved through the meshing of the meshing gears, external gear rings, and internal gear rings by a single drive motor.

[0012] Preferably, the tooling mounting plate is further provided with a protective cover plate covering the drive motor to protect the drive motor.

[0013] Preferably, the air pressure chamber is an annular cavity with a central hole at its center through which the motor shaft of the drive motor passes.

[0014] The beneficial effects of the present invention are as follows: The inductor coil clamping device provided by the present invention only requires one set of drive units to complete the clamping of multiple sets of products under a certain air pressure. Since multiple sets of products are clamped under the same air pressure, the air pressure in the piston chamber can be kept the same, thereby ensuring a high consistency of clamping effect. Even when clamping products of different models and sizes simultaneously, the pressure applied to the products can be kept the same due to the same air pressure. The same pressure can also reduce the probability of mechanical damage to the inductor coil during the clamping process. Attached Figure Description

[0025] Example 1

[0026] like Figure 1-7 As shown, an inductor coil clamping device, in this embodiment, includes a tooling base plate 1, a tooling mounting plate 2, and a pneumatic cavity 3 located between the tooling base plate 1 and the tooling mounting plate 2. The tooling mounting plate 2 is mounted on the drive end of a handling robot, allowing the handling robot to drive the entire clamping device for transport via the tooling mounting plate 2. The pneumatic cavity 3 is filled with pressurized gas, which is typically injected into the pneumatic cavity 3 under high pressure, thus generating a certain pressure within the pneumatic cavity 3. Multiple sets of [unspecified components] are evenly arranged circumferentially on the tooling base plate 1. Each clamping station is equipped with a clamping assembly 4. The clamping assembly 4 includes multiple gripper units 41 mounted on the fixture base plate 1 for clamping and positioning the inductor coil. The gripper units 41 are connected to the pneumatic chamber 3 via connectors 5. A drive unit 6 is also mounted on the fixture base plate 1. The drive unit 6 drives multiple connectors 5 to rotate synchronously, thereby driving the multiple gripper units 41 in each clamping assembly 4 to perform clamping or releasing actions to complete the synchronous clamping or unloading operation of the product below each clamping station.

[0027] Thus, the inductor coil clamping device of the present invention only requires one drive unit 6 to complete the synchronous clamping of multiple products. Since multiple products are clamped under the same air pressure, the air pressure in the piston chamber 44 can be kept the same, thereby ensuring a high consistency of clamping effect. Even when clamping products of different models and sizes simultaneously, the pressure applied to the products can be kept the same due to the same air pressure. The same pressure can also reduce the probability of mechanical damage to the inductor coil during clamping. Furthermore, the air pressure in the air chamber 3 can be adjusted by gas purging at any time according to the consumption, and the adjustment is also relatively convenient.

[0028] Example 2

[0029] An inductor coil clamping device, in this embodiment, is a further limitation based on embodiment 1. Each clamping assembly 4 includes four sets of clamping claw units 41 arranged in a cross shape. The inner sides of the two opposing clamping claw units 41 are provided with limiting groove cavities whose shape is adapted to the inductor coil. The clamping claw units 41 are elastic claws, which are used to further reduce the local pressure on the surface of the inductor coil during clamping.

[0030] The gripper unit 41 is connected to a set of piston rods 42 via a connecting block 10. One end of the piston rod 42 is positioned in the spring cavity 43, and the other end is positioned in the piston cavity 44. The connecting piece 5 is mounted on the tooling base plate 1 and is connected to the pneumatic cavity 3 via a rotary joint 9. When the connecting piece 5 is driven by the drive unit 6 to rotate and connect with the piston cavity 44, the gas in the pneumatic cavity 3 is pressed into the piston cavity 44 to achieve the clamping action of the gripper unit 41. When the piston cavity 44 is depressurized, the spring in the spring cavity 43 is used to release the gripper unit 41 by pressing the piston block.

[0031] The connector 5 includes an inner cavity 51 located in the inner layer and an outer cavity 52 located in the outer layer. The inner cavity 51 has a connecting pipe 53 that passes through the outer cavity 52 to connect to the piston cavity 44 and a connecting pipe 54 that connects to the rotary joint 9. When the connector 5 rotates, so that the connecting pipe 53 connects to the piston cavity 44, the gas in the pneumatic chamber 3 enters the piston cavity 44 through the connecting pipe 54 and the connecting pipe 53 to drive the piston block in the piston cavity 44 to move, so as to realize the clamping action of the gripper unit 41.

[0032] The outer cavity 52 is provided with a pressure relief hole 55 and a pressure relief groove 56. The connecting piece 5 is transferred and installed in the mounting groove 57 of the tooling base plate 1. There is also a gap between the mounting groove 57 and the outer cavity 52 for the pressure relief groove 56 to release air. The piston cavity 44 is also provided with sealing blocks 58 on both sides for abutting against the outside of the outer cavity 52. ​​When the piston cavity 44 is pressed, the connecting pipe 53 is connected to the piston cavity 44 and the pressure relief hole 55 abuts against the sealing block 58. When the piston cavity 44 is depressurized, the connecting piece 5 rotates until the connecting pipe 53 abuts against the sealing block 58 and the pressure relief hole 55 is connected to the piston cavity 44. Then the air pressure in the piston cavity 44 enters the outer cavity 52 through the pressure relief hole 55 and is then discharged through the pressure relief groove 56.

[0033] An external gear ring 59 is fixed to the outside of the connecting tube 54, and each clamping assembly 4 also includes an internal gear ring 45 that is transferred and installed on the tooling base plate 1 and meshes internally with the multiple sets of external gear rings 59 of the clamping assembly 4. The drive unit 6 includes a drive motor installed at the center of the tooling mounting plate 2. A set of meshing gears 7 is fixed to the outside of the drive shaft of the drive motor. The meshing gears 7 are located at the center of the multiple sets of internal gear rings 45 and mesh externally with the internal gear rings 45. In this way, synchronous clamping and releasing operations at different clamping positions on the tooling base plate 1 can be achieved by a single drive motor through the meshing of the meshing gears 7, external gear rings 59, and internal gear rings 45.

[0034] The tooling mounting plate 2 is also equipped with a protective cover plate 8 that covers the drive motor to protect the drive motor.

[0035] The air pressure chamber 3 is an annular cavity with a central hole in the center through which the motor shaft of the drive motor passes.

[0036] The working principle of this invention is as follows: The inductor coil clamping device provided by this invention, during operation, is driven by a handling robot via a tooling mounting plate 2 to move onto a positioning fixture. Each clamping station corresponds to a set of positioning positions on the positioning fixture. The drive motor is then activated to rotate, driving the gripper unit 41 of each clamping station to clamp and fix the corresponding product. The entire process requires only one drive motor for rotation. The air pressure chamber 3 is connected to an air source via an air pipe. When the air pressure in the air pressure chamber 3 decreases, the air source can be opened to allow ventilation. Thus, the device only requires one drive unit 6 to clamp multiple sets of products under a certain air pressure. Since multiple sets of products are clamped under the same air pressure, the air pressure in the piston chamber 44 is the same, ensuring a high consistency in clamping effect. Even when simultaneously clamping products of different sizes, the pressure applied to the products is the same due to the same air pressure. This same pressure also reduces the probability of mechanical damage to the inductor coil during clamping.
