Description

Technical Field

[0001] The present application relates to the field of welding machines, and in particular to a fully automatic welding device for L-shaped metal sheets. Background Art

[0002] In the process of automobile assembly and processing, when connecting two parts, L-shaped metal sheets are often used for connection. In order to improve the efficiency of part assembly, in the actual production and processing process, nuts are often pre-welded on the two arms of the L-shaped metal sheet.

[0003] In the prior art, the common L-shaped metal sheet nut welding machine mainly includes a frame. A hydraulic driving mechanism and a support are fixedly installed on the frame. The driving end of the hydraulic driving mechanism is fixedly installed with a welding mechanism. The welding head of the welding mechanism is coaxially arranged directly above the support. A socket for fixing nuts and L-shaped metal sheets is installed on the support.

[0004] In the actual welding process, the operator needs to pre-align the mounting holes on the L-shaped metal sheet with the socket, place the L-shaped metal sheet on the support, then sleeve the nut to be welded on the socket, and then start the welding machine. The hydraulic driving mechanism drives the welding head to move down to weld and fix the nut on the L-shaped metal sheet.

[0005] However, the method of manual-assisted feeding requires a large amount of manpower and has a low welding efficiency, so there is room for improvement. Utility Model Content

[0006] In order to save the manpower required for welding nuts on L-shaped metal sheets and improve the welding efficiency, the present application provides a fully automatic welding device for L-shaped metal sheets.

[0007] The fully automatic welding device for L-shaped metal sheets provided by the present application adopts the following technical solutions:

[0008] A fully automatic welding device for L-shaped metal sheets includes a frame, on which a workpiece feeding mechanism, a workpiece temporary storage mechanism, a workpiece loading manipulator and a nut automatic conveyor are fixedly installed;

[0009] The workpiece feeding mechanism includes a workpiece vibrating disk and a conveying channel. The outlet end of the workpiece vibrating disk is fixedly connected to the inlet end of the conveying channel. The workpiece temporary storage mechanism is communicated with the outlet end of the conveying channel. The workpiece loading manipulator is located between the support and the workpiece temporary storage mechanism;

[0010] An inclined downward discharge channel is fixedly installed on the frame, and the inlet end of the discharge channel is located beside the support.

[0011] By adopting the above technical solution, during the actual welding process, the L-shaped metal sheets can be continuously sent out to the workpiece temporary storage mechanism through the workpiece vibrating bowl and the conveying channel. The workpiece loading manipulator transfers the workpiece to the support, and then the nut automatic conveyor automatically assembles the nuts on the workpiece. The hydraulic driving mechanism on the frame drives the welding mechanism to move downward, so that the welding head on the welding mechanism welds the nuts on the L-shaped metal sheets. After the nuts on one arm of the L-shaped metal sheet are welded, the workpiece loading manipulator places the other arm of the L-shaped metal sheet on the support to complete the welding process of the nuts on the other arm. After the welding process of the two arms of the L-shaped metal sheet is completed, the workpiece loading manipulator transfers the workpiece to the discharge channel, and the workpiece is sent out through the inclined channel. Through the mutual cooperation and use of the workpiece feeding mechanism, the workpiece temporary storage mechanism, the workpiece loading manipulator, and the nut automatic conveyor, the technical effects of automatically clamping the L-shaped metal sheets, automatically clamping the nuts, and automatically discharging can be achieved, effectively saving the labor required for welding nuts on the L-shaped metal sheets and improving the welding efficiency of the welding machine.

[0014] By adopting the above technical solution, when the L-shaped metal sheets are sent out through the conveying channel, the first cylinder drives the loading plate to slide past the discharge end of the conveying channel, and the L-shaped metal sheets slide into the placement groove. The first cylinder continuously extends the cylinder shaft to send out the L-shaped metal sheets, preparing for the workpiece loading manipulator to grab the L-shaped metal sheets.

[0017] By adopting the above technical solution, the fixing block and the L-shaped blocking portion can reduce the occurrence of the L-shaped metal sheets falling off the loading plate. And when the loading plate sends out the L-shaped metal sheets, the shielding block covers the outlet of the conveying channel, preventing the L-shaped metal sheets in the conveying channel from falling.

[0018] Preferably, a second cylinder is fixedly installed on the base, and a positioning plate is fixedly installed at the driving shaft end of the second cylinder. The positioning plate is located at the opening side of the placement groove, and a cushion block adapted to the workpiece is fixedly installed on the positioning plate.

[0019] By adopting the above technical solution, after the first cylinder sends out the loading plate, the second cylinder extends the cylinder shaft to drive the positioning plate to slide out and abut against the notch of the sent-out placement groove, which can further reduce the occurrence of the L-shaped metal sheet falling out of the placement groove. The cushion block extends into the L-shaped metal sheet to further position the L-shaped metal sheet.

[0020] Preferably, a guide rail is fixedly installed on the base, a slider is fixedly installed at the bottom of the loading plate, and a chute adapted to the guide rail is formed on the slider.

[0022] Preferably, two mounting seats are fixedly installed on the base, and limiting members are respectively fixedly installed on the two mounting seats;

[0023] A limiting portion is fixedly installed on one side of the base away from the conveying channel, and the limiting portion is located between the two limiting members.

[0024] By adopting the above technical solution, the two limiting members can limit the position of the loading plate and reduce the occurrence of the loading plate falling off the base.

[0025] Preferably, the workpiece loading manipulator includes a manipulator body, the manipulator body is fixedly installed on the frame, and a pneumatic gripper is fixedly installed at the driving end of the manipulator body.

[0026] By adopting the above technical solution, the robotic arm drives the starting gripper to move, and the processes of material taking, loading, and unloading can be completed.
