Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding production lines, in particular to a workbench and intelligent chamfering equipment. Background Art

[0002] In automated welding production lines, robotic arms are commonly used to carry out various welding processes to improve welding efficiency. For example, for welding of plate-like parts, it is often necessary to first chamfer the steel plate on the production line. As the level of intelligence of welding robots increases, intelligent welding production lines have emerged. As a result, the chamfering process has also been fully automated and intelligent.

[0003] The current intelligent chamfering equipment can realize fully automatic and autonomous chamfering, using multiple evenly distributed electromagnets on its workbench to effectively adsorb and fix the steel plate, and then the robotic arms around the workbench autonomously chamfer the fixed steel plate.

[0004] However, the arrangement of the electromagnets on the existing workbench is unreasonable. When the electromagnets are energized, the adsorption force of the workpiece steel plate is insufficient, resulting in loose fixation of the workpiece steel plate and vibration during the chamfering process, affecting the stability and safety of the robot arm in performing the chamfering operation. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to firmly fix a steel plate workpiece on an intelligent chamfering device.

[0006] In order to solve the above problems, the utility model provides a workbench for chamfering, comprising:

[0007] Base;

[0008] A plurality of cross beams are arranged parallel to each other in a transverse direction, and the plurality of cross beams are arranged on the base in a longitudinal direction;

[0009] A plurality of transmission rollers are arranged alternately with the plurality of beams on the base;

[0010] A plurality of lifting mechanisms are arranged at intervals in the transverse direction on both sides of the longitudinal direction of each crossbeam, and the plurality of lifting mechanisms at each crossbeam are symmetrically arranged about the crossbeam; and

[0011] A plurality of electromagnets are arranged one by one on each of the lifting mechanisms, and the lifting mechanisms are used to lift the electromagnets.

[0014] A plurality of the cross beams are arranged at intervals on the groove, and two ends of each cross beam are respectively connected to two side walls of the groove.

[0015] Optionally, the lifting mechanism includes a piston cylinder and a piston rod which cooperate with each other.

[0016] Optionally, the lifting mechanism further includes a housing. The piston cylinder is arranged in the housing. The piston rod is arranged above the piston cylinder and passes through the housing to enter the piston cylinder, and the electromagnet is fixed on the piston rod.

[0017] Optionally, the lifting mechanism further includes a top plate, a bottom plate and guide columns.

[0018] The top plate is fixed at the top end of the piston rod, and the electromagnet is fixed on the top plate. The bottom plate is arranged in the housing and fixed at the top end of the piston cylinder. The top ends of the guide columns are connected to the top plate, and the bottom ends of the guide columns are inserted into the bottom plate.

[0019] Optionally, there are two guide columns which are respectively arranged on two sides of the piston cylinder.

[0020] Optionally, a vision sensor is arranged above the base, and the vision sensor faces the lifting mechanism.

[0025] By arranging multiple lifting mechanisms at each cross beam symmetrically with respect to the cross beam, and arranging multiple electromagnets one by one on each lifting mechanism, multiple lifting mechanisms and multiple electromagnets are provided on both the longitudinal front and rear sides of each cross beam, resulting in a greater adsorption force on the workpiece at each cross beam, increasing the adsorption force on the workpiece at any section of each cross beam, and making full use of the spacing between the cross beam and the transmission roller, thus occupying less space. Moreover, the cross beams and the transmission rollers are arranged alternately in sequence, which can not only ensure the transportation and transfer efficiency of the workpiece by multiple transmission rollers, but also enable multiple electromagnets to form a uniformly distributed and effective adsorption force on the workpiece by means of the uniform arrangement of multiple cross beams, preventing uneven adsorption and fixation on one side of the workpiece, so as to meet the fixation requirements of various different shaped plate-like workpieces, and firmly fix the steel plate workpiece on the intelligent chamfering device. This can prevent the vibration of the workpiece during the chamfering process, which may affect the stability, safety and processing quality of the chamfering. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] See Figures 1 to 3 , this embodiment provides a workbench for chamfering, including:

[0037] Base 1;

[0038] A plurality of cross beams 2, arranged parallel to each other along the transverse direction, and the plurality of cross beams 2 are arranged longitudinally on the base 1;

[0039] A plurality of drive rollers 5, arranged alternately with the plurality of cross beams 2 on the base 1;

[0040] A plurality of lifting mechanisms 3, arranged at intervals along the transverse direction on both longitudinal sides of each cross beam 2, and the plurality of lifting mechanisms 3 at each cross beam 2 are symmetrically arranged with respect to the cross beam 2; and

[0041] A plurality of electromagnets 4, provided on each of the lifting mechanisms 3 one by one, and the lifting mechanism 3 is used to lift the electromagnet 4.

[0042] It should be noted that the plurality of lifting mechanisms 3 at each cross beam 2 are symmetrically arranged with respect to the cross beam 2. That is to say, two lifting mechanisms 3 are a group, and multiple groups of lifting mechanisms 3 are arranged along the cross beam 2, and the two lifting mechanisms 3 in each group are respectively arranged on both longitudinal sides of the cross beam 2, and the two lifting mechanisms 3 in each group are arranged oppositely.

[0044] In use, multiple lifting mechanisms 3 are in the lowered state, and the electromagnets 4 are in the powered-off state. The height of the driving rollers 5 is higher than that of the lifting mechanisms 3. By rotating the multiple driving rollers 5, the workpiece is conveyed above the multiple lifting mechanisms 3 and stopped. Then, the multiple lifting mechanisms 3 rise to separate the workpiece from the multiple driving rollers 5. Then, the electromagnets 4 are powered on to adsorb and fix the workpiece.

[0045] By arranging the multiple lifting mechanisms 3 at each of the crossbeams 2 symmetrically with respect to the crossbeam 2, and arranging the multiple electromagnets 4 one-to-one on each of the lifting mechanisms 3, multiple lifting mechanisms 3 and multiple electromagnets 4 are provided on both the longitudinal front and rear sides of each crossbeam 2, which increases the adsorption force on the workpiece at each crossbeam 2, increases the adsorption force on the workpiece at any section of each crossbeam 2, and makes full use of the space between the crossbeam 2 and the driving rollers 5, occupying less space. Moreover, the crossbeams 2 and the driving rollers 5 are arranged alternately in sequence, which can not only ensure the transportation and transfer efficiency of the multiple driving rollers 5 for the workpiece, but also enable the multiple electromagnets 4 to form a uniform and effective adsorption force on the workpiece by virtue of the uniform arrangement of the multiple crossbeams 2, preventing uneven adsorption and fixation on one side of the workpiece, so as to meet the fixation requirements of various different-shaped plate-like workpieces, and firmly fix the steel plate workpiece on the intelligent chamfering device. This prevents the occurrence of workpiece vibration during the chamfering process, which may affect the chamfering stability, safety, and processing quality.

[0055] See Figures 1 to 3 , Further, the lifting mechanism 3 further includes a top plate 34, a bottom plate 35, and guide columns 36.

[0057] The cooperation of the top plate 34, the bottom plate 35, and the guide columns 36 ensures the accurate vertical lifting of the electromagnet 4.

[0058] See Figures 1 to 3 , Further, there are two guide columns 36 which are respectively disposed on both sides of the piston cylinder 31.

[0059] The two guide columns 36 provide accurate guidance.

[0060] See Figures 1 to 3 , Further, a vision sensor 6 is disposed above the base 1, and the vision sensor 6 is oriented towards the lifting mechanism 3.

[0061] The vision sensor 6 is used to detect the positions of the workpieces on the plurality of electromagnets 4, and then accordingly, the drive roller 5 can be controlled to rotate by a corresponding angle, or several of the plurality of lifting mechanisms 3 can be controlled to lift, realizing the intelligent operation of the workbench.

[0062] See Figures 1 to 3 , Further, there are a plurality of vision sensors 6, and the plurality of vision sensors 6 are disposed at one longitudinal end of the base 1, and the plurality of vision sensors 6 are arranged at intervals in sequence along the transverse direction.

Then, according to the obtained workpiece contour shape and dimensions, the control system uses the robotic arm to move the chamfering mechanism close to the edge of the plate-like workpiece and starts the chamfering operation on the workpiece, realizing the automatic recognition and automatic chamfering operation of the workpiece by the whole set of equipment, making the chamfering operation automated and intelligent. Such as the chamfering device described in the published invention "An Intelligent Steel Plate Cutting System and Method (202211253994.9)".
