Description

Technical Field

[0001] This utility model relates to the field of flexible manufacturing technology, specifically to an intelligent assembly workstation. Background Technology

[0002] Flexible manufacturing models are actually widespread, such as customization. This consumer-oriented, demand-driven production approach contrasts with the traditional mass production model. Flexible manufacturing tests the responsiveness of the production line and supply chain.

[0003] To ensure that the same equipment can assemble a variety of different customized products, an intelligent assembly station has been designed on the market. This station transports pallets through connecting lines that run through the station and extend to the outside at both ends. By placing the workpieces on the pallets, the various parts of the workpieces can be transferred into the station. After the robotic arm places the parts of different workpieces onto different assembly fixtures for assembly, the robotic arm then picks up the workpieces and places them on the pallets for transfer to the outside of the station. Since the different assembly fixtures are in different positions, multiple sets of robotic arm movements need to be set.

[0004] In the aforementioned existing technologies, a robotic arm is required to grasp workpieces within a relatively confined workstation. Due to the limited space inside the workstation, the robotic arm performs numerous actions during the process of grasping different workpieces and placing them into assembly fixtures at different locations. For example, placing the first workpiece into the first assembly fixture and the second workpiece into the second assembly fixture involves two sets of mechanical actions. Therefore, it is necessary to set up two or more sets of significantly different motion programs in a narrow environment, which is not only difficult to design but also carries a high risk of collisions. Hence, the intelligent assembly workstation is proposed to solve the aforementioned problems. Utility Model Content

[0005] Based on the above description, this utility model provides an intelligent assembly workstation to solve the problem that the existing assembly workstation has a relatively narrow internal space, which makes the motion design of the robotic arm to transport different workpieces to different assembly fixtures difficult and the risk of collision is high.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: Intelligent assembly station, including: station body and assembly tooling position adjustment mechanism;

[0007] The workstation body has a workbench inside and a connecting line running through it on the outside. The two ends of the connecting line are located on the outside of the workstation body. The connecting line is used to transport a pallet. An articulated robot is installed on the upper surface of the workbench.

[0008] The assembly tooling position adjustment mechanism includes a turntable mechanism. The upper surface of the turntable mechanism is provided with a first assembly tooling and a second conversion tooling. The upper surface of the worktable is provided with a positioning detection element along the outer edge of the turntable mechanism. The upper surface of the turntable mechanism is provided with a mating element corresponding to the positioning detection element.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the workbench is located inside the main body of the workstation, which includes a tray inlet and a tray outlet. One end of the connecting line extends from the tray inlet and the other end extends from the tray outlet. Workpieces are placed on the tray.

[0011] Furthermore, the turntable mechanism includes a servo motor disposed on the lower surface of the worktable, and the output shaft of the servo motor passes through and extends to the upper surface of the worktable.

[0012] Furthermore, a rotating disk is provided at the top of the output shaft of the servo motor. The upper surface of the rotating disk is provided with a first assembly fixture, a second assembly fixture, and multiple threaded holes. The multiple threaded holes are distributed in a ring at equal intervals along the outer edge of the rotating disk.

[0013] Furthermore, the internal threaded connection of the threaded hole is provided with two threaded posts extending above the rotating disk, and the two threaded posts are respectively disposed on opposite sides of the first assembly fixture and the second conversion fixture.

[0014] Furthermore, the positioning detection component includes a vertical plate disposed above the worktable surface and corresponding to one side of the threaded column. A photoelectric switch is disposed on the side of the vertical plate facing the turntable mechanism. A horizontal plate is disposed at the top of the vertical plate, and an RFID reader is disposed on the lower surface of the horizontal plate.

[0015] Furthermore, a pipe clamp is fitted on the outside of the threaded column. The pipe clamp includes two semi-circular pipe clamps connected by screws and nuts. A protruding plate is provided on the side of the semi-circular pipe clamp away from the center of the rotating disk. One side of the protruding plate extends into the interior of the photoelectric switch and is located between the transmitting end and the receiving end of the photoelectric switch.

[0016] Furthermore, an RFID tag is provided on the upper surface of the protruding plate, and the RFID tag is located directly below the RFID reader, which is used to scan the RFID tag.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. This utility model sets up components such as an assembly tooling position adjustment mechanism and an articulated robotic arm. Through the cooperation between the two components, the positions of the first assembly tooling and the second assembly tooling change under the action of the turntable mechanism, while the large-range movement trajectory of the articulated robotic arm remains unchanged. That is, after the first assembly tooling is used, the second assembly tooling moves to the position of the first assembly tooling. Thus, the articulated robotic arm only needs to make small-range fine adjustments to achieve the effect of transporting different assembly workpieces into the corresponding assembly tooling.

[0019] 2. By configuring the turntable mechanism, positioning detection components, and mating parts, the assembly fixture is positioned. When the turntable rotates the two assembly fixtures, the mating parts move in a circular motion around the center of the turntable. During this process, the protruding plate passes between the transmitter and receiver of the photoelectric switch. Simultaneously, the RFID reader identifies the RFID code that moves beneath it, ensuring that the assembly fixture moves precisely to the position of the positioning detection components.

[0029] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0031] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0032] Please see Figure 1 and Figure 2 The intelligent assembly station includes: the main body of the station 1 and the assembly tooling position adjustment mechanism;

[0033] The workstation body 1 has a workbench 2 inside and a connecting line 4 running through it on the outside. The two ends of the connecting line 4 are located on the outside of the workstation body 1. The connecting line 4 is used to transport a pallet 5. An articulated robot 3 is installed on the upper surface of the workbench 2.

[0034] The workbench 2 is located inside the workstation body 1. The workstation body 1 includes a tray inlet and a tray outlet. One end of the connecting line 4 extends from the tray inlet and the other end extends from the tray outlet. Workpieces are placed on the tray.

[0035] Based on the above, the main body 1, workbench 2, articulated robot 3, connecting line 4, and conveyor tray 5 are all part of the existing technology of intelligent assembly workstations. After the conveyor tray 5 is transported to the interior of the main body 1 of the workstation via the connecting line 4, the articulated robot 3 grabs the workpiece on the upper surface of the tray 5 and moves the workpiece to the interior of the corresponding assembly fixture for assembly. After the assembly is completed, the articulated robot 3 moves the workpiece back to the tray 5 and sends it out. Since the focus of this technical solution is on the cooperative operation between the articulated robot 3 and the position adjustment mechanism of the assembly fixture, other structures of the existing intelligent assembly workstations are not described here.

[0036] like Figures 2-4 As shown, the assembly tooling position adjustment mechanism includes a turntable mechanism 6, and the upper surface of the turntable mechanism 6 is provided with a first assembly tooling 7 and a second assembly tooling 8.

[0037] The turntable mechanism 6 includes a servo motor 64 disposed on the lower surface of the worktable 2. The servo motor 64 is preferably a servo motor of model MHMD042G1V-B. The output shaft of the servo motor 64 passes through and extends to the upper surface of the worktable 2. A rotating disk 61 is disposed at the top of the output shaft of the servo motor 64. The upper surface of the rotating disk 61 is provided with a first assembly fixture 7, a second assembly fixture 8, and a plurality of threaded holes 62. The plurality of threaded holes 62 are distributed in a ring at equal intervals along the outer edge of the rotating disk 61.

[0038] The threaded hole 62 is internally threaded with two threaded posts 63 extending above the rotating disk 61. The two threaded posts 63 are respectively located on opposite sides of the first assembly fixture 7 and the second conversion fixture 8.

[0039] Based on the above, when the servo motor 64 is powered on, it drives the rotating disk 61 to rotate. When the rotating disk 61 rotates, it drives the first assembly fixture 7, the second assembly fixture 8, and the two threaded columns 63 to perform circumferential motion together, thereby achieving the effect of changing the position of the assembly fixtures.

[0040] like Figures 3-6 As shown, a positioning detection element 9 is provided on the upper surface of the worktable 2 along the outer edge of the turntable mechanism 6, and a mating part 10 corresponding to the positioning detection element 9 is provided on the upper surface of the turntable mechanism 6.

[0041] The positioning detection component 9 includes a vertical plate 91 disposed above the workbench 2 and corresponding to the threaded column 63 on one side. A photoelectric switch 93 is disposed on the side of the vertical plate 91 facing the turntable mechanism 6. A horizontal plate 92 is disposed at the top of the vertical plate 91, and an RFID reader 94 is disposed on the lower surface of the horizontal plate 92.

[0042] The threaded column 63 is fitted with a pipe clamp, which includes two semi-circular pipe clamps 101 connected by screws and nuts. The semi-circular pipe clamp 101 is provided with an extension plate 102 on the side opposite to the center of the rotating disk 61. One side of the extension plate 102 extends into the interior of the photoelectric switch 93 and is located between the transmitting end and the receiving end of the photoelectric switch 93.

[0043] An RFID tag 103 is provided on the upper surface of the protruding plate 102. The RFID tag 103 is located directly below the RFID reader 94, which is used to scan the RFID tag 103.

[0044] Based on the above, the mating part 10 moves together with the threaded column 63. At this time, the RFID code 103 set on the surface of the two mating parts 10 corresponds to two different assembly fixtures, thereby realizing the identification of the assembly fixtures.

[0045] When the rotating disk 61 rotates, it drives the two assembly fixtures and the threaded column 63 to move together. When a mating part 10 moves to the position of the positioning detection part 9, the state of the photoelectric switch 93 changes because the protruding plate 102 moves between the transmitting end and the receiving end of the photoelectric switch 93. This signal is transmitted to the servo motor 64, causing the servo motor 64 to stop rotating. At this time, the assembly fixture is in place. At the same time, the RFID reader 94 scans the RFID identification code 103 to identify which fixture is in place, thereby ensuring that the workpiece to be assembled is compatible with the assembly fixture.

[0046] In summary, this intelligent assembly station, based on existing technologies (such as...), Figure 7 Based on the existing technology shown, an improvement is made by adding an assembly tooling position adjustment mechanism. Through the cooperation between the turntable mechanism 6, the positioning detection component 9 and the mating component 10, the position of the assembly tooling can be changed. Furthermore, through the positioning detection component 9 and the mating component 10, the position of the assembly tooling can be fixed after the change, and the tooling can be identified, that is, the tooling moves to the area where the articulated robot 3 moves.

[0047] Compared to Figure 7 In terms of existing technology, this workstation changes the position of the assembly tooling so that the main motion trajectory of the articulated robot 3 remains unchanged. When assembling different workpieces, the movements of the articulated robot 3 are only adjusted within a small range. On the one hand, this makes it easier for the staff to design the movements of the articulated robot, and on the other hand, the relatively fixed motion trajectory can greatly reduce the risk of collision.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
