Description

Technical Field

[0001] The utility model relates to the technical field of robot welding workstations, in particular to a multi-station material tray for a robot welding workstation with a protective function. Background Art

[0002] A robotic welding workstation is an automated welding production line consisting of a welding robot, welding equipment, a control system, and other auxiliary equipment.

[0003] The primary function of a robotic welding workstation is to achieve efficient, high-precision, and high-quality welding, thereby improving production efficiency and product quality. During the welding process, the welding robot performs automated movements and operations according to pre-programmed procedures, thus automating the welding process. Furthermore, the robotic welding workstation can be equipped with equipment such as a vision system to enable real-time monitoring and control of weld quality and dimensions, further improving welding quality and efficiency.

[0004] For example, an industrial robot welding workstation with application number 201921144192.8 has a welding fixture designed with a four-position shifting mechanism. The robot can weld four products continuously, greatly improving its work efficiency. The workpiece tray is mounted on the workbench, and 12 sets of workpieces are loaded at a time. After welding 12 sets of products, the robot automatically stops and waits for manual loading and unloading. The robot also has a built-in welding gun cleaning system to better ensure the quality of the weld. However, the device still has certain defects.

[0005] There is no protective mechanism on the material tray. When the robot is welding the workpiece in the fixed hole, the workpieces on other workstations are not fixed well and are prone to falling from the fixed hole, posing a major safety hazard to the operating staff.

[0006] Therefore, we propose a multi-station material tray for a robot welding workstation with protective function to solve the problems raised above. Utility Model Content

[0007] The purpose of the present utility model is to provide a multi-station material tray with a protective function for a robot welding workstation, so as to solve the problem proposed in the above-mentioned background technology that the material tray in the robot welding workstation on the current market is not provided with a protective mechanism. When the robot is welding the workpiece in the fixing hole, the workpieces on other stations are not fixed well and are easy to fall from the fixing hole, thereby posing a greater safety hazard to the operating staff.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a multi-station material tray for a robot welding workstation with a protective function, comprising a workbench and a material tray body, a protective cover being installed above the workbench via a telescopic spring, a material tray body being installed above the workbench via a rotating shaft mechanism, and a fixed station and a heat insulation pad being installed on the upper surface of the material tray body;

[0009] A protective plate is installed on the upper surface of the workbench, and a ball screw is installed on the upper surface of the workbench through a bearing seat, a forward and reverse motor is installed on the right side of the protective plate, and a transmission shaft is installed on the left side of the forward and reverse motor through an output shaft, and a fan mechanism is installed on the left end of the transmission shaft, a first bevel gear is fixedly installed on the transmission shaft, a second bevel gear is fixedly installed on the ball screw, and a connecting plate is installed on the ball screw, a connecting rod is installed on the left side of the connecting plate, and a slide groove is opened on the left side of the protective plate.

[0010] Preferably, two telescopic springs are provided, and the lower end of the telescopic spring is fixedly connected to the upper surface of the workbench, and the upper end of the telescopic spring is detachably connected to the lower surface of the protective cover.

[0011] With the above structural design, after long-term use, the surface of the protective cover will be damaged by collision with the workpiece, so it is convenient to disassemble the protective cover and the telescopic spring to complete the disassembly of the protective cover, thereby facilitating the replacement of the protective cover.

[0012] Preferably, the rotating shaft mechanism is connected to the driving mechanism, and the driving mechanism is located below the workbench, and the rotating shaft mechanism is fixedly connected to the tray body.

[0013] With the above structural design, the driving mechanism drives the rotating shaft mechanism to rotate, and the rotating shaft mechanism drives the upper material tray body, so that the workpieces on the material tray body can be welded in sequence by the robot, thereby improving the welding efficiency of the robot.

[0014] Preferably, the center line of the tray body and the center line of the protective sleeve coincide with each other, and the diameter of the protective sleeve is smaller than the diameter of the tray body.

[0015] The above structural design allows the protective sleeve to move upward along the tray body when it is forced to move upward. Therefore, when the workpiece on the tray body falls, it can be blocked by the protective sleeve to prevent the workpiece from falling, thereby protecting both the workpiece and the staff.

[0016] Preferably, the fixed station and the thermal insulation pad are distributed in a ring structure, and the thermal insulation pad passes through the fixed station, and the thermal insulation pad abuts against the upper surface of the tray body.

[0017] With the above structural design, the thermal insulation pad can insulate the heat generated by the robot when welding the workpiece, so that the staff will not directly touch the material tray body when installing the workpiece at a fixed workstation, thereby preventing the staff from being scalded. At the same time, when replacing the thermal insulation pad, the thermal insulation pad can be directly pulled out upwards.

[0018] Preferably, two connecting rods are provided, and the connecting rods are fixedly connected to the connecting plate. The connecting plate is located below the protective sleeve, and a slider is installed on the right side of the connecting plate.

[0021] The above-mentioned structural design is adopted to start the forward and reverse motors. The forward and reverse motors are self-locking motors. The forward and reverse motors drive the transmission shaft to rotate. The transmission shaft drives the fan mechanism and the first bevel gear to rotate. The fan mechanism blows air to one side of the material tray body, which can clean the dust on the workpiece or the material tray body, and also play a certain heat dissipation role. The first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the ball screw to rotate. The ball screw drives the connecting plate to move up or down. The slider on the connecting plate can move up or down along the slide groove. When moving upward, it can drive the protective cover to move upward through the connecting rod to protect the material tray body. Moving downward can make the connecting rod away from the protective cover, and the protective cover moves downward and resets under the action of the telescopic spring.
