Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, and in particular to a translational robot and production line. Background Technology

[0002] A translational robot is a mechanical device used to transport workpieces in a production line. A stamped product requires multiple stamping processes to transform from a sheet metal workpiece into a finished stamped product. Translational robots are used between adjacent stamping machines to move the products. With the widespread application of robots, the demands for their efficiency and precision are constantly increasing.

[0003] The applicant's prior Chinese patent application CN202211423153.8 discloses a moving component for a planar robotic arm, a robotic arm, and a stamping production line. The moving component includes a fixed plate, a moving assembly, and a driving assembly. The fixed plate has a concave center and convex sides forming a first groove. The moving assembly includes a moving plate with a first surface and a second surface. Multiple first rolling assemblies are positioned between the first surface and the bottom of the first groove. Multiple second rolling assemblies are positioned on the convex surfaces of the fixed plate and contact the second surface. This invention uses the first rolling assemblies to support the moving plate, replacing the direct contact between the fixed plate and the moving plate. The second rolling assemblies guide the moving plate, achieving guiding contact. Compared to existing sliding contact, the friction of rolling contact is less than that of sliding contact, thus increasing the moving speed of the moving plate assembly and improving work efficiency. However, the drive in this solution uses a linear motor, which has significant inertia during movement, making precise displacement control difficult.

[0004] This invention overcomes the shortcomings of the prior art and provides a translational robot and production line that can further improve conveying accuracy. Utility Model Content

[0026] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] like Figure 1-6 The diagram shown is a schematic representation of an embodiment of the translational manipulator provided by this utility model.

[0028] Please refer to Figure 1-6This embodiment is used for the horizontal conveying and movement of workpieces in a production line, and is particularly suitable for the movement of workpieces in a stamping production line. This embodiment includes a frame 100, a lifting assembly 200, a translation assembly 300, a gripping assembly 400, and a transfer table 500. The frame 100 is equipped with the lifting assembly 200, which is connected to the translation assembly 300. The lifting assembly 200 drives the translation assembly 300 to move up and down, thereby causing the workpiece gripped by the translation assembly 300 to move up and down. The translation assembly 300 drives the gripping assembly 400 to move horizontally, thereby causing the workpiece gripped by the gripping assembly 400 to move horizontally, thus achieving horizontal movement of the workpiece.

[0029] The translation component 300 includes a first motor 310, a first gear 320, a first rack 330, and a moving crossbar 340. The first rack 330 is fixedly connected to the moving crossbar 340. The first motor 310 is driven by the first gear 320, and the first gear 320 meshes with the first rack 330. The first motor 310 drives the moving crossbar 340 to move horizontally. Specifically, the output end of the first motor 310 is driven by the first gear 320 via a synchronous belt 311. Compared to motor drive, the gear and rack transmission method results in less inertia and smaller displacement error, enabling more precise displacement control, improving workpiece movement accuracy, and reducing the workload of workpiece centering.

[0030] The two ends of the movable crossbar 340 are respectively connected to gripping components 400, which are used to grip workpieces. A transfer platform 500 is provided at the lower middle part of the movable crossbar 340, which is used to carry workpieces and transfer them. Specifically, the lifting component 200 drives the gripping component 400 to move down to the gripping position of the loading position to grip the workpiece at the loading position. After the gripping component 400 at the first end of the movable crossbar 340 grips the workpiece, the lifting component 200 rises, causing the gripped workpiece to be lifted. Driven by the first motor 310, the movable crossbar 340 moves the gripping component 400 to move above the transfer platform 500. The lifting component 200 then moves the gripping component 400 down, and the gripping component 400 places the workpiece on the transfer platform 500. When the gripping component 400 at the head end of the moving crossbar 340 repeats the above operation, the gripping component 400 at the tail end of the moving crossbar 340 moves above the transfer table 500 to grip the workpiece and move it to the work station, thereby completing the transportation of the workpiece from the loading position to the work station.

[0031] In one embodiment, the lifting assembly 200 includes a lifting bracket 210, a lifting guide rail 220, a second motor 240, a second gear 230, and a second rack (not shown). The second motor is mounted on the lifting bracket 210. The second rack and the lifting guide rail 220 are fixedly connected to the frame 100. The second rack and the lifting guide rail 220 are vertically arranged. The second motor is driven by the second gear 230, which meshes with the second rack. The lifting bracket 210 is slidably connected to the lifting guide rail 220 via a slider 211. The translation assembly 300 is connected to the lifting bracket 210. The lifting assembly 200 also adopts the same gear and rack transmission method as the translation assembly 300, and has the same structural advantages as the translation assembly 300, with low inertia and easy precise control. Its principle and specific structure will not be described in detail.

[0032] In one embodiment, a first motor 310 is mounted on a lifting bracket 210. A first rack 330 is connected to the upper side of a moving crossbar 340. Guide grooves 341 are provided on both sides of the moving crossbar 340, and the length of the guide grooves 341 matches the length of the moving crossbar 340. The lifting bracket 210 is connected to multiple rollers 213 via a cantilever 212. The multiple rollers 213 are arranged sequentially at intervals along the direction of the guide grooves 341. The rollers 213 are located within the guide grooves 341 and make rolling contact with the guide grooves 341. The frictional force of the moving crossbar 340 during movement is reduced by the cooperation of the guide grooves 341 and the rollers 213.

[0033] Furthermore, V-shaped guide rails 342 are respectively provided on the upper and lower sides of the guide groove 341, and the upper and lower V-shaped guide rails 342 are arranged opposite to each other. The rolling surface of the roller 213 is provided with a V-shaped groove 214, and the V-shaped groove 214 matches the V-shaped guide rail 342. The V-shaped guide rail 342 and the V-shaped groove 214 serve as a limit to restrict the moving crossbar 340 from shifting to both sides when it moves.

[0034] In one embodiment, the gripping component 400 includes a support frame 410, which is connected to a plurality of support rods 420. The support rods 420 are connected to suction nozzles 430, which can be vacuum nozzles or magnetic nozzles. The support frame 410 has a symmetrical structure, and the support rods 420 are detachably connected to the support frame 410. Therefore, the position and number of support rods 420 can be adjusted according to the size of the workpiece. The suction nozzles 430 are used to adsorb workpieces. Vacuum nozzles are suitable for adsorbing workpieces of various materials, while magnetic nozzles are suitable for adsorbing workpieces made of metal or iron alloys.

[0035] In one embodiment, the transfer platform 500 includes a transfer frame 510 and a bearing surface 520. The transfer frame 510 and the bearing surface 520 are connected by a lead screw 530 and a handwheel 540. The lead screw 530 is fixedly connected to the bearing surface 520 and threadedly connected to the transfer frame 510. The handwheel 540 is connected to the lead screw 530. By rotating the handwheel 540, the lead screw 530 is rotated, thereby raising or lowering the bearing surface 520 to adjust its height. The transfer frame 510 is fixedly connected to the horizontal ground, providing support.

[0036] Furthermore, the bearing surface 520 is provided with multiple limiting blocks 521, and the position of the limiting blocks 521 is adjusted by pushing them with a cylinder 522. The multiple limiting blocks 521 form a limiting area for placing the workpiece and limiting the workpiece. The cylinder 522 pushes the limiting blocks 521 to move, thereby pushing the workpiece to achieve centering adjustment and adjustment of the size of the limiting area.

[0037] In one embodiment, a control panel 600 is included. The control panel 600 is connected to the lifting assembly 200, the translation assembly 300, and the gripping assembly 400. Control commands are input through the control panel 600 to control the lifting assembly 200, the translation assembly 300, and the gripping assembly 400. The control panel 600 is movably connected to the frame 100 via an adjusting rod 610 to adjust the position of the control panel 600 for user convenience.

[0038] This embodiment also provides a production line embodiment, including the translational robot embodiment described above. Specifically, the production line embodiment can be a stamping production line.

[0039] In summary, the translational manipulator embodiment provided by this utility model achieves the vertical movement of the translational component and the gripping component connected to the translational component through the lifting component, thereby achieving the vertical movement of the workpiece. The horizontal movement of the gripping component is achieved through the translational component, thereby achieving the horizontal movement of the workpiece. The translational component drives the moving crossbar to move through the gear and rack transmission method. This movement method has less inertia, and the stopping point of the gripping component driven by the moving crossbar is more precise.
