Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to an automated positioning and conveying device for assembling sills. Background Technology

[0002] With the popularization of automation technology, more and more factories and enterprises are using automated production line equipment to improve overall production efficiency. However, the production process of sill structures often requires multiple riveting and clamping processes. These processes often require precise positioning of the workpiece to ensure high-precision processing and facilitate subsequent assembly and use. However, since the raw material workpiece of the sill is a long steel frame with internal grooves, existing clamping and inspection fixtures cannot effectively clamp and transport this type of workpiece stably. Furthermore, they cannot stably align the workpiece with the processing datum without damaging it. Therefore, the overall processing efficiency and precision are low, failing to meet current usage requirements. Utility Model Content

[0003] The purpose of this utility model is to provide an automated positioning and conveying device for assembling sills, which solves the technical problems of poor clamping and alignment of long strip workpieces and poor transportation efficiency in the prior art, and achieves the technical effect of improving the overall clamping accuracy and improving the processing and transportation efficiency.

[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0005] An automated positioning and conveying device for assembling sills includes a workbench, a positioning and detection structure, and a feeding structure. The main body of the workbench is constructed of a steel frame. The workbench has a groove in the middle, and a feeding structure is fixed inside the groove for feeding materials in conjunction with other processes.

[0006] The positioning and detection structure is located at the upper end of the worktable and spans the groove. The positioning and detection structure includes a sensor mounting base and a moving structure. The sensor mounting base is located on one side of the upper end of the worktable and has an opening at one end facing the groove for mounting a sensor to detect the workpiece. There are two sets of moving structures, symmetrically arranged with the axis of the feeding structure as the reference. The main body of the moving structure is a lead screw moving structure, with a transmission seat at one end connected to a motor drive. A moving jaw is rotatably connected to one side of the moving structure. The upper end of the worktable has a slide rail that slides in cooperation with the moving jaw. The moving jaw is used to adjust the placement position of the workpiece.

[0007] The feeding structure is located on the side of the workbench near the positioning and detection structure. The feeding structure is positioned directly opposite the feeding structure. The height of the conveyor belt of the feeding structure is higher than that of the workbench. The feeding structure is used to straighten the workpiece to cooperate with the feeding structure for transportation.

[0008] As an improvement, a motor is fixed inside the worktable. The motor's shaft is connected to the lead screw of the moving structure via a transmission seat. A rotation sensor is connected to one side of the motor's shaft to identify and control the motor's rotation. The sensor mounting base contains a vision sensor and a laser sensor to identify the workpiece's mounting position.

[0009] As an improvement, the worktable is equipped with a fixed gripper inside. The fixed gripper is located above the feeding structure. One side of the fixed gripper has a mounting plate that is fixedly connected to the steel frame. The steel frame is set in the gap of the feeding structure. The fixed gripper is set upward and is at the same height as the moving gripper. The fixed gripper is used to temporarily grab the workpiece and adjust the position of the workpiece in conjunction with the moving gripper.

[0010] As an improvement, the feeding structure includes a conveyor belt, a fixed frame, and a motor. The fixed frame is a rectangular frame in general. The conveyor belt is symmetrically arranged on both sides of the fixed frame through rotating wheels. The motor is located on the side of the fixed frame away from the feeding structure. The rotating shaft of the motor is connected to the rotating shaft of the conveyor belt through a sprocket structure.

[0011] As an improvement, the feeding structure includes a moving track, a gripping claw, and an electric push rod. The moving track is arranged along the axis of the worktable and extends out of the worktable from the side near the feeding structure. The moving track has a sprocket drive structure inside. The lower end of the gripping claw has a slider that slides and pulls in conjunction with the slide rail of the moving track. The electric push rod is located below the moving track, and its push rod part is fixedly connected to the moving track to raise the height of the gripping claw for easy position adjustment.

[0012] The beneficial effects of this utility model are as follows: by setting up a feeding structure, the automatic feeding function of small batch workpiece materials can be met, thereby improving the overall feeding and processing efficiency; by setting up a feeding structure, the workpiece can be stably transported in conjunction with multiple processes, while further improving the overall transportation and processing efficiency; by setting up a positioning and detection mechanism, the workpiece can be sorted without damaging it, and the workpiece can be precisely aligned with the processing reference with multiple sets of sensors and moving jaws, thereby improving the overall processing accuracy.

[0024] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] like Figures 1 to 6As shown, an automated positioning and conveying device for assembling a sill includes a workbench 1, a positioning and detection structure 2, and a feeding structure 3. The main body of the workbench 1 is constructed from a steel frame 101. The workbench 1 has a groove in the middle, and a feeding structure 4 is fixed inside the groove for feeding materials in conjunction with other processes. The positioning and detection structure 2 is located at the upper end of the workbench 1 and spans the groove. The positioning and detection structure 2 includes a sensor mounting base 201 and a moving structure 202. The sensor mounting base 201 is located on one side of the upper end of the workbench 1 and has an opening at one end facing the groove for mounting a sensor to detect the workpiece. The moving structure 202... There are two sets of feeding structures symmetrically arranged with the axis of the feeding structure 4 as the reference. The main body of the moving structure 202 is a lead screw moving structure, with a transmission seat 102 at one end connected to the motor drive. A moving claw 203 is rotatably connected to one side of the moving structure 202. The upper end of the worktable 1 has a slide rail that slides in cooperation with the moving claw 203. The moving claw 203 is used to adjust the placement position of the workpiece. The loading structure 3 is located on the side of the worktable 1 near the positioning detection structure 2. The loading structure 3 is set directly opposite the feeding structure 4. The height of the conveyor belt 301 of the loading structure 3 is higher than that of the worktable 1. The loading structure 3 is used to straighten the workpiece for transportation with the feeding structure 4. The upper end of the worktable 1 has multiple mounting plates that are fixedly connected to the steel frame 101. The inner side of the mounting plates has threaded holes to facilitate the assembly of other processing equipment. The lower end of the worktable 1 is fixed with multiple sets of adjustable feet for stable installation of the worktable 1.

[0026] When in use, the workpiece is placed stably on the upper end of the feeding structure 3. When processing is performed, the feeding structure 3 will send the workpiece to the upper part of the feeding structure 4, and then, with the help of the corresponding chuck, it will be gripped and sent to the sensor mounting base 201. At this time, the sensor inside the sensor mounting base 201 will identify the relative position of the current workpiece and itself. When the workpiece deviates from the processing reference, the controller will send a start command to the corresponding motor and drive the moving structure 202 through the transmission base 102, so that it drives the moving chuck 203 to push the workpiece and align it with the processing reference, which facilitates the processing of subsequent processes.

[0027] During use, a single position sensor cannot fully identify the current position of the workpiece, which can easily lead to misjudgment. As a result, the workpiece cannot be aligned with the corresponding machining reference. At the same time, the overall workpiece handling flexibility is poor, affecting the overall machining quality and efficiency. Therefore, the following improvements are made:

[0028] A motor is fixed to the inner side of the worktable 1. The motor's shaft is connected to the lead screw of the moving structure 202 via a transmission seat 102. A rotation sensor is connected to one side of the motor's shaft to identify and control the motor's rotation. The sensor mounting seat 201 contains a vision sensor and a laser sensor to identify the workpiece's mounting position. A fixed jaw 204 is located inside the worktable 1, above the feeding structure 4. One side of the fixed jaw 204 has a mounting plate fixedly connected to the steel frame 101, which is positioned in the gap of the feeding structure 4. The fixed jaw 204 faces upwards and is at the same height as the moving jaw 203. The fixed jaw 204 is used to temporarily grip the workpiece and adjust its position in conjunction with the moving jaw 203. Symmetrical pads are arranged on both sides of the fixed jaw 204, located below the workpiece, to accommodate the fixed jaw 204. The inner wall of the fixed jaw 204 is smooth to facilitate workpiece sliding within it.

[0029] The feeding structure 3 includes a conveyor belt 301, a fixed frame 302, and a motor 303. The fixed frame 302 is a rectangular frame. The conveyor belt 301 is symmetrically arranged on both sides of the fixed frame 302 via rotating wheels. The motor 303 is located on the side of the fixed frame 302 away from the feeding structure 4. The shaft of the motor 303 is connected to the shaft of the conveyor belt 301 via a sprocket structure. The feeding structure 4 includes a moving track 401, a gripping claw 402, and an electric push rod 403. The moving track 401 is arranged along the axis of the worktable 1 and extends out of the worktable 1 from the side closest to the feeding structure 3. The moving track 401 has a sprocket drive structure inside. The lower end of the gripping claw 402 has a slider that slides and is connected to the slide rail of the moving track 401. The electric push rod 403 is located below the moving track 401, and its push rod part is fixedly connected to the moving track 401 to raise the height of the gripping claw 402 for easy position adjustment. The lower ends of the movable jaw 203, the fixed jaw 204, and the gripping jaw 402 can be equipped with a cylinder push rod structure, which can realize the lateral movement of the jaw structure, thereby realizing the gripping action, further improving the overall workpiece fixing and processing effect, and facilitating workpiece adjustment.

[0030] When in use, the conveyor belt 301 of the feeding structure 3 smoothly delivers the workpiece to the inside of the gripping jaw 402. The gripping jaw 402 then closes to securely grip the workpiece and moves above the fixed jaw 204. In conjunction with the electric push rod 403, the overall height is lowered. At this point, the gripping jaw 402 releases the workpiece from its current position, and the fixed jaw 204 opens and grips the corresponding workpiece. Subsequently, the vision sensor and laser sensor determine the visual relative position of the workpiece to the sensor mounting base 201 and the positioning of both ends, thereby controlling the corresponding moving jaw 203 to grip one end of the workpiece and move it to align it with the processing reference. Then, the moving structure 202 drives the moving jaw 203 to reset, the gripping jaw 402 opens, and in conjunction with the electric push rod 403, the overall height is raised to grip the workpiece. The fixed jaw 204 opens to release the workpiece from its fixation. At this point, the feeding structure 4 can send the aligned workpiece to the next processing step.

[0031] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
