Description

Technical Field

[0001] This application belongs to the field of motor technology, and more specifically, relates to a dual-station welding device. Background Technology

[0002] After the rotor is wound, it needs to be spot-welded. To automate the spot welding process, multiple rotors are typically transported via a conveyor line, and a robotic arm moves the rotors to be spot-welded to the welding station, where a spot welding machine performs the spot welding. After spot welding, the rotors are then transported back to the conveyor line by the robotic arm and moved to the next station.

[0003] However, the rotor is transported by the reciprocating movement of the robotic arm between the transmission line and the spot welding position. Since the robotic arm can only transport one rotor at a time, the spot welding machine is in a stopped and waiting state during the rotor transport process. This results in low spot welding efficiency of the rotor, which in turn reduces production efficiency. Utility Model Content

This dual-station spot welding equipment includes a frame 20, a transmission line 30, two material handling grippers 1, a material handling transverse movement unit 2, a spot welding machine 40, two support seats 50, two rotary drive components 60, a transverse movement seat 70, and a spot welding drive unit 3. Optionally, the frame 20 is provided with a material loading position and a spot welding position at intervals; the two support seats 50 are respectively aligned with the material loading position and the spot welding position, and the two support seats 50 can respectively support the workpiece 10; the two rotary drive components 60 are respectively connected to the two support seats 50, and the two rotary drive components 60 can respectively drive the two support seats 50 to rotate, thus realizing rotary spot welding of the workpiece 10. The workpiece 10 can be a rotor, and the rotary drive component 60 can be a motor. The transverse movement seat 70 can support the two rotary drive components 60. A spot welding drive unit 3 can be mounted on the frame 20 and is connected to a support base 50. The spot welding drive unit 3 can drive two support bases 50 to move alternately between the loading position and the spot welding position. After the workpiece 10 at the spot welding position is spot welded, the spot welding drive unit 3 drives the support base 50 to move out and simultaneously drives another support base 50 to move to the spot welding position to continue the spot welding operation, thus repeating the alternating operation. A material handling and traversing unit 2 is mounted on the frame 20 and connected to two material handling grippers 1 respectively. The material handling and traversing unit 2 is used to drive the two material handling grippers 1 to reciprocate between the transmission line 30 and the spot welding position. A spot welding machine 40 is mounted at the spot welding position and can perform spot welding operations on the workpiece 10 located at the spot welding position. The spot welding machine 40 is a conventional device commonly used in the market and will not be described in detail here. This structure allows the workpiece 10 to be transported via the transmission line 30. Two support seats 50 support the workpiece 10, which can be positioned at the loading position and the spot welding position, respectively. A rotary drive 60 drives the support seats 50 to rotate, cooperating with the spot welding machine 40 to spot weld the workpiece 10 at the spot welding position. After spot welding, the spot welding drive unit 3 moves the workpiece 10 from the loading position to the spot welding position, and the spot welding machine 40 continues spot welding the next workpiece 10. Simultaneously, one of the pick-up grippers 1 moves the spot-welded product from the spot welding position to the transmission line 30, while the other pick-up gripper 1 moves the workpiece 10 from the transmission line 30 to an empty support seat 50. Thus, by alternating pick-up by the two pick-up grippers 1 and by the alternating movement of the two support seats 50 between the loading and spot welding positions, continuous spot welding operation of the spot welding machine 40 can be achieved, reducing the spot welding waiting time and improving spot welding efficiency.

The material-grabbing lifting seat 12 is slidably mounted on the material-grabbing base 11 via a guide rail pair. The material-grabbing lifting drive 13 can be a cylinder, electric cylinder, etc.; the clamping drive 15 can be a finger cylinder. This structure allows the two picking arms 14 to pick up and place the workpiece 10 via the clamping drive 15; and the picking lifting drive 13 drives the picking lifting seat 12 to lift along the Z-axis, thereby adjusting the height of the workpiece 10 along the Z-axis.

[0048] In one embodiment, see Figure 2 In one specific embodiment of the dual-station spot welding equipment provided in this application, two material-collecting bases 11 are connected by a connecting plate 16.

The connecting plate 16 has oblong holes at both ends, and each material-collecting base 11 has threaded holes at corresponding oblong holes. The connecting plate 16 is connected to each material-collecting base 11 by fasteners such as screws and bolts. By locking the fasteners at different positions in the oblong holes, the distance between the two material-collecting jaws 1 can be adjusted, improving the versatility of the dual-station spot welding equipment.

Two material handling grippers 1 are respectively connected to the material handling conveyor belt 24. The material handling drive component 25 can be a motor; the two material handling grippers 1 are connected to the material handling conveyor belt 24 through two material handling bases 11.
