[0037] Reference Figure 1 This utility model provides a robotic production line equipment for welding trolley panels, including: a welding machine 1, a robotic arm 2, a feeding conveyor assembly 3, an unloading conveyor assembly 4, and a positioning fixture 5. The robotic arm 2 is positioned on one side of the welding machine 1.

[0038] Specifically, in the above embodiment, the trolley panel to be welded is placed on the feeding conveyor assembly 3. The feeding conveyor assembly 3 moves the trolley panel to be welded along the production line. The positioning fixture 5 pushes the trolley panel to be welded on the feeding conveyor assembly 3 to a designated position on the positioning fixture 5. The robotic arm 2 grabs the trolley panel to be welded on the positioning fixture 5 and controls the trolley panel to be welded to move to the welding position of the welding machine 1.

The cutting plate 55 is fixedly connected to the connecting plate 54 and is located above the feeding conveying assembly 3, extending along the width direction of the feeding conveying assembly 3.

[0043] Specifically, when the previous trolley panel is welded, the first linear drive unit drives the slider 53 to move downward, and the slider 53 drives the cutting plate 55 to move downward through the connecting plate 54, blocking the conveying route of the trolley panel; after the pushing mechanism pushes the trolley panel away, the first linear drive unit drives the slider 53 to move upward, and drives the cutting plate 55 to move upward, so that the trolley panel can pass under the cutting plate 55.

[0044] In some embodiments, the pushing mechanism includes a second fixed plate 56, a pushing plate 57, and a second linear drive. The second fixed plate 56 is fixedly connected to the conveying bracket 31 of the feeding conveying assembly 3. The second linear drive is disposed on the second fixed plate 56. The pushing plate 57 is connected to the movable end of the second linear drive. The second linear drive can drive the pushing plate 57 to move along the width direction of the feeding conveying assembly 3, thereby pushing the trolley panel onto the positioning mechanism.

[0045] Specifically, when the cutting plate 55 prevents the trolley panel from moving, the second linear drive extends to drive the pusher plate 57 to move, pushing the trolley panel onto the positioning mechanism. The second fixing plate 56 is used to support the pusher plate 57 and the second linear drive.

[0046] In some embodiments, the positioning mechanism includes a support plate 58, a positioning block 59, a limiting block, and a third linear drive.

[0047] Specifically, after the trolley panel moves onto the support plate 58, the third linear drive extends to move the positioning block 59, positioning the trolley panel between the positioning block 59 and the limit block, making it easier for the robotic arm 2 to grasp it. The first, second, and third linear drive components can be linear motors or cylinders.

[0048] In some embodiments, the height of the feeding conveyor 3 is higher than the height of the unloading conveyor 4, and the feeding conveyor 3 and the unloading conveyor 4 have opposite conveying directions.

[0049] In some embodiments, reference Figure 4 The loading conveyor assembly 3 and unloading conveyor assembly 4 include a conveyor bracket 31, a motor 32, a transmission mechanism 33, and a conveyor belt 34.
