Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to a gantry robot. Background Technology

[0002] A gantry robot (also known as a Cartesian coordinate robot or gantry robot) is an automated material handling device based on a Cartesian coordinate system (X, Y, and Z axes). It performs operations such as workpiece gripping, transfer, and assembly through program control, and is widely used in CNC machine tool loading and unloading, production line logistics transfer, and heavy workpiece handling. Although this technology is relatively mature, existing designs still have the following significant drawbacks:

[0003] Most gantry robots use grippers or vacuum suction cups to pick up workpieces. When picking up and putting down workpieces, the robot is always above the workpiece. This is not suitable for some work scenarios, such as when sending a workpiece to a certain position or station, but the top of that position or station is blocked or interfered with by objects (framework, baffle), and the workpiece can only be sent in from the side. In this case, traditional gantry robots cannot send the workpiece in. For example, sending a workpiece into a carriage with only a rear opening; or sending a workpiece into a stamping machine or edge trimming machine with stamping or blanking parts on the top.

[0004] When traditional gantry robots place workpieces into enclosed equipment, the vertical direction is obstructed by the top plate of the equipment. The workpieces can only be hoisted to the side of the equipment and then manually pushed in, which is inefficient and prone to workpiece damage. If a six-axis robot is used for lateral delivery, the cost is high and the space required is large. Utility Model Content

[0005] The purpose of this utility model is to provide a gantry robot with a simple and reasonable structural design and stable and reliable operation; the loading platform can extend and retract forward and backward, making it convenient to extend from the side into a closed or obstructed space at the top to unload workpieces or objects.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A gantry robot includes a gantry frame, a horizontal sliding plate, a lifting column, and a loading slide assembly;

[0008] The gantry frame is a steel structure support frame, consisting of two columns and a top beam forming a portal structure, which serves as the mounting frame for the entire robotic arm;

[0009] Two horizontal slide rails are provided above the crossbeam; a horizontal rack is provided between the horizontal slide rails.

[0010] The horizontal sliding plate is a flat panel, vertically installed, with a horizontal slider fixed to its rear side; the horizontal slider is sleeved on the horizontal slide rail. A horizontally positioned transverse motor is located at the front of the horizontal sliding plate, and the output shaft of the transverse motor is connected to a drive gear, which meshes with a horizontal rack. Rotation of the transverse motor drives the drive gear to rotate, thus driving the horizontal sliding plate to slide left and right along the horizontal slide rail.

[0011] The front side of the horizontal sliding plate is also provided with a vertical slider, and the rear side is also provided with a horizontally arranged lifting motor, the output shaft of which is connected to the second drive gear.

[0012] The rear side of the lifting column is provided with two vertically arranged vertical slide rails, and a vertical rack is vertically arranged between the vertical slide rails. The vertical slider is sleeved on the vertical slide rails, and the second drive gear meshes with the vertical rack. By rotating the lifting motor, the second drive gear is driven to rotate, which drives the horizontal sliding plate to slide up and down along the vertical slide rails.

[0013] The bottom end of the lifting column is fixed with a horizontally arranged loading slide assembly.

[0014] The loading slide assembly includes a connecting frame, a loading platform, and a slide motor. The connecting frame is a frame with openings at both ends and a cavity in the middle. The loading platform is located within the cavity of the connecting frame. The slide motor is located on the right outer wall of the connecting frame, and sliders are located on both its left and right inner walls. The loading platform has slide rails on both its left and right sides, and a horizontally arranged rack on its right outer wall. The output shaft of the slide motor is connected to a drive gear. The sliders are mounted on the slide rails, and the drive gear meshes with the rack for transmission. The loading platform is slidably connected to the connecting frame via the slide rails and sliders, and is driven to slide back and forth by the slide motor through the drive gear and rack.

[0015] The platform includes an unloading motor, a conveyor belt, a drive roller, a driven roller, a support plate, and a mounting frame. The mounting frame is horizontally positioned, with a horizontally positioned drive roller and driven roller at its front and rear ends, respectively. The conveyor belt is fitted onto the drive roller and driven roller at its front and rear ends, respectively. The output shaft of the unloading motor is connected to the drive roller, driving its rotation and thus the conveyor belt. The support plate is horizontally positioned below the conveyor belt, with its edges fixed to the mounting frame, to support the conveyor belt and maintain its horizontal position.

[0016] The beneficial effects of this utility model are:

[0017] Its structural design is simple and reasonable, and its operation is stable and reliable; the platform can be extended and retracted back and forth, making it convenient to unload workpieces or objects from the side into the closed or obstructed space at the top. Attached Figure Description
