Description

Technical Field

[0001] This invention relates to the field of motor manufacturing equipment technology, and in particular to a PCB feeding robot for assembling motor stator PCBs and wires. Background Technology

[0002] The assembly of the motor stator PCB and wires is the core process in motor stator production and a key link between stator winding manufacturing and overall machine assembly. This process requires precisely positioning the stator-specific PCB to the pre-set installation position on the stator, connecting the wires led out from the stator winding to the pre-set pads on the PCB, and achieving electrical connection through soldering. It also requires auxiliary processes such as wire fixing and solder joint protection to ensure the conduction of the stator circuit and the stable transmission of electrical control signals, laying the electrical control foundation for the normal operation of the motor.

[0003] The PCB unloading robot for motor stator PCB and wire assembly is a specialized automated material handling device adapted to the motor stator PCB and wire assembly process. It is mainly used for PCB loading and unloading operations in the stator assembly stage. It can accurately grab the stator-specific PCB, and after positioning and transfer, it can be placed stably in the pre-set assembly position of the stator. It is adapted to the PCB specifications and stator assembly station layout, and can be used in conjunction with subsequent wire soldering and other processes. It replaces manual material unloading, improves material unloading accuracy and efficiency, and ensures the continuity and consistency of the assembly process.

[0004] Traditional clamping structures for motor stator PCB assembly have poor adaptability, cannot grip PCBs of different sizes, and are difficult to meet the needs of flexible production. Rigid clamping can easily damage the circuit board and surface components, and insufficient positioning accuracy affects the assembly quality.

[0005] Therefore, it is necessary to provide a PCB unloading robot for assembling motor stator PCBs and wires to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a PCB unloading robot for assembling motor stator PCBs and wires, which solves the problems of poor adaptability, easy damage to components, low positioning accuracy, and poor assembly quality caused by traditional clamping structures for motor stator PCBs.

[0026] The working principle of the PCB unloading robot for assembling motor stator PCBs and wires provided by this invention is as follows: Two adjustment ports 18 are provided at the bottom of the movable frame 4. Then, two first linkage components 17 are installed inside the two adjustment ports 18. The transmission component 13 can be used to rotate the two first linkage components 17 synchronously, thereby adjusting the position of the two sets of first pneumatic clamps 12 to accommodate PCB boards of different widths. Combined with the first pneumatic clamps 12, which can move within a small range, precise gripping and unloading of the PCB board can be achieved. Furthermore, the two second pneumatic clamps 14 installed by the first adjustment component 5 can clamp the sides of the PCB board. The bottom bracket 21 at the bottom of the second pneumatic clamp 14 can support the bottom of the PCB board, reducing the risk of the PCB board falling during loading or movement. In actual use, first adjust the two sets of first pneumatic clamps 12 according to the size of the PCB board using the transmission component 13, ensuring that the distance between the two pneumatic grippers 122 in each set of first pneumatic clamps 12 allows for normal movement of the pneumatic grippers, facilitating clamping of the PCB board. Then, adjust the two second pneumatic clamps using the first adjustment component 5. The spacing between the two pneumatic clamps 14 is also designed to maintain the distance between the two second pneumatic clamps 14 and the PCB board, facilitating the movement of the pneumatic grippers and the gripping of the PCB board. After adjustment, the movable frame 4 is moved to the PCB board placement area by the movable base 3. Then, the movable frame 4 is driven downward by the lifting structure 6, so that the positions of the first pneumatic clamp 12 and the second pneumatic clamp 14 correspond to the outer surface of the PCB board. Then, the pneumatic synchronization valve 8 controls the first pneumatic clamp 12 and the second pneumatic clamp 14 to work synchronously, and with the help of the pressure monitoring component 123, the front, back and sides of the PCB board are clamped. Then, the gripped PCB board is moved above the bracket 15. Then, the lifting structure 6 is activated to move the PCB board downward, and the bottom of the PCB board is aligned with the limit bolt at the top of the bracket 15. After the alignment is completed, the two second pneumatic clamps 14 are released first, and then the two sets of first pneumatic clamps 12 are released, thus completing the unloading of the PCB board. After that, the wires only need to be inserted into the holes on the PCB board as required to complete the alignment and proceed with subsequent processing.

[0027] Compared with related technologies, the PCB unloading robot for assembling motor stator PCBs and wires provided by the present invention has the following advantages: To improve the applicability and gripping stability of the PCB unloading robot for assembling motor stator PCBs and wires, two adjustment ports 18 are provided at the bottom of the movable frame 4. Then, two first linkage components 17 are installed inside the two adjustment ports 18. The transmission component 13 can then synchronize the rotation of the two first linkage components 17, thereby adjusting the position of the two sets of first pneumatic grippers 12. This allows for adaptation to PCBs of different widths. Combined with the first pneumatic grippers 12, which can move within a small range, precise gripping and unloading of PCBs can be achieved. Furthermore, the two second pneumatic grippers 14 installed by the first adjustment component 5 can further enhance the gripping and unloading of P... The PCB board is clamped on both sides, and the bottom bracket 21 at the bottom of the second pneumatic clamp 14 can support the bottom of the PCB board, which can reduce the risk of the PCB board falling during loading or movement. This design allows for quick adjustment of the spacing of each set of first pneumatic clamps 12 as needed. With the pneumatic gripper 122, it can be adapted to PCB boards of different sizes. At the same time, the pneumatic clamps can precisely control the clamping force, which can reduce the probability of damage to the PCB board during clamping. The two second pneumatic clamps 14 located on both sides, together with the bottom bracket 21, can provide protection for the PCB board and increase the stability of the PCB board during movement.

The third pneumatic clamp 34 on the L-shaped bracket 28 can fix the PCB board to the four corners after it is properly connected to the L-shaped bracket 28, increasing the stability during wire connection. During the downward movement of the movable frame 4, the connecting bolts 30 on both sides will insert into the connecting holes 25 at the top of the support frame 24. In the middle, the contact sensor 31 at the bottom of the docking bolt 30 detects that the lifting structure 6 stops working after docking is completed. At the same time, the third pneumatic clamp 34 works to clamp and fix the PCB board. Then, it is only necessary to release the second pneumatic clamp 14 and the first pneumatic clamp 12 in sequence to accurately insert the wire leads into the PCB board. Through this design, multiple L-shaped brackets 28 can be used independently to clamp the PCB board. With the support frame 24, docking bolt 30 and the structure under the movable frame 4, the material placement and positioning can be completed synchronously, improving the material placement accuracy and stability.
