Description

Technical Field

[0001] This utility model relates to the field of gripping device technology, specifically to an electromagnetic suction mechanism with buffer. Background Technology

[0002] In the field of robotics, particularly in automated production lines and logistics systems, there is a high demand for gripping devices capable of accurately and stably grasping and transporting workpieces. This demand has driven the research and optimization of key components of gripping devices. Electromagnetic suction mechanisms are a crucial component of gripping devices; however, traditional electromagnetic suction mechanisms, when directly used for grasping and transporting workpieces, may be damaged by the impact and vibration generated during the moment of attraction, affecting their service life and stability. Furthermore, this impact may also damage the workpiece itself, reducing product quality.

[0003] Therefore, improvements are needed to the existing electromagnetic suction mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a buffered electromagnetic attraction mechanism, solving the problem of poor structural stability in existing electromagnetic attraction mechanisms and thus improving their service life. The implementation of this technical solution is as follows:

[0005] An electromagnetic suction mechanism with buffer includes: a mounting base, a buffer assembly, an electromagnetic chuck, and a detection assembly; the buffer assembly includes a first support plate, a spring, a bolt, a limiting nut, and a second support plate; the first support plate is connected to the mounting base; the bolt passes through the first and second support plates in sequence and is fixedly connected to the limiting nut; the spring is sleeved on the bolt; the electromagnetic chuck is installed below the second support plate; the detection assembly includes a detection element, which is installed on the second support plate.

[0006] Preferably, the mounting base is provided with a fixing plate and a column, the fixing plate is fixedly connected to the column, and a first reinforcing rib is provided at the joint between the fixing plate and the column.

[0007] Preferably, the mounting base is further provided with a support portion, which is fixedly connected to the column, and a second reinforcing rib is provided at the joint between the support portion and the column.

[0008] Preferably, the mounting base is further provided with a mounting part, which is fixedly connected to the bearing part, and a third reinforcing rib is provided at the joint between the mounting part and the bearing part.

[0009] Preferably, the mounting part is fixedly connected to the first support plate.

[0010] Preferably, there are two mounting parts, which are respectively located at both ends of the support part.

[0011] Preferably, the cross-sectional area of ​​the first support plate is larger than the cross-sectional area of ​​the mounting portion.

[0012] Preferably, it also includes a control box, which is mounted on the support.

[0013] This application also relates to a gripping device, including the aforementioned electromagnetic suction mechanism with buffer.

[0014] Compared with the prior art, this application has the following advantages:

[0015] (1) When the electromagnetic suction mechanism of this technical solution is used, it is installed on the robotic arm of the gripping device. The robotic arm moves to a suitable position above the workpiece to be transported, so that the electromagnetic chuck moves downward and contacts the workpiece to be magnetically attracted. When it moves to a certain position, the detection component is triggered, the electromagnetic suction mechanism stops moving downward, and then the electromagnetic chuck is energized to attract the workpiece. The robotic arm transports the workpiece to the designated position. After reaching the designated position, the electromagnetic chuck is de-energized, thus completing the transport work. Through the combination of the robotic arm and the electromagnetic chuck, the workpiece can be quickly and accurately grasped and transported, reducing the time and labor costs of manual operation.

[0016] (2) When the electromagnetic suction mechanism attracts the workpiece and the electromagnetic chuck contacts the workpiece, vibration will occur due to pressure or tension, which will cause the second support plate connected to the electromagnetic chuck to move relative to it. Since the first support plate and the second support plate are fixed by bolts and limit nuts, the first support plate and the second support plate will tend to move relative to each other. At this time, the spring begins to undergo elastic deformation, absorbs and stores the impact energy, and achieves a buffering effect. In this way, the buffer component reduces the impact and vibration on the electromagnetic suction mechanism during the adsorption process, while protecting the structure of the electromagnetic suction mechanism itself.

[0017] (3) When the electromagnetic chuck is above the workpiece, the detection component starts to work to detect whether the falling position is limited, so as to protect the electromagnetic chuck mechanism and the gripping device. Attached Figure Description

[0033] To further understand the utility model's content, features, and effects, the following embodiments are provided, along with detailed descriptions in conjunction with the accompanying drawings:

[0034] This application relates to a buffered electromagnetic suction mechanism, a key component in the field of robotic equipment technology, specifically a key component of a gripping device. One application scenario of this type of gripping device is as follows: the electromagnetic suction mechanism is mounted on the robotic arm of the gripping device. The robotic arm drives the electromagnetic suction mechanism to move above the workpiece, causing the electromagnetic chuck to move downwards and contact the workpiece to be magnetically attracted. When it moves to a certain position, the detection component is triggered, the electromagnetic suction mechanism stops moving downwards, and then the electromagnetic chuck is energized to attract the workpiece. The robotic arm transports the workpiece to the designated position. After reaching the designated position, the electromagnetic chuck is de-energized, thus completing the transport operation.

[0035] The above describes the application scenarios of the electromagnetic attraction mechanism with buffer in this application, in order to facilitate understanding of the purpose of this application. It can also be used in other scenarios, which will not be elaborated here.

[0036] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Embodiments of this application provide a buffered electromagnetic attraction mechanism, such as... Figure 1-3 As shown, it includes: an assembly base 1, a buffer assembly 2, an electromagnetic chuck 3, and a detection assembly 4; the buffer assembly 2 includes a first support plate 21, a spring 22, a bolt 23, a limiting nut 24, and a second support plate 25. The first support plate 21 is connected to the assembly base 1. The bolt 23 passes through the first support plate 21 and the second support plate 25 in sequence and is fixedly connected to the limiting nut 24. The spring 22 is sleeved on the bolt 23. The electromagnetic chuck 3 is installed below the second support plate 25. The detection assembly 4 includes a detection element 42, which is installed on the second support plate 25.

[0038] Reference Figure 2 and Figure 3 The mounting base 1 includes a fixed plate 11, a column 12, a bearing part 13, and a mounting part 14. The fixed plate 11 is a disc, and a plurality of first threaded holes 111 are provided on the fixed plate 11. The first threaded holes 111 are through holes for threading screws and other connecting parts to fix the fixed plate 11 to the robotic arm (not shown). Furthermore, the fixed plate 11 is fixedly connected to the column 12. A first reinforcing rib 112 is provided at the joint between the fixed plate 11 and the column 12. The first reinforcing rib 112 can effectively enhance the connection strength between the fixed plate 11 and the column 12 and prevent the fixed plate 11 and the column 12 from deforming when the device is working.

[0039] Furthermore, the column 12 is a hollow cuboid structure, and the column 12 is fixedly connected to the support part 13. A second reinforcing rib 121 is provided at the joint between the column 12 and the support part 13 to enhance the strength and rigidity of the column 12 and the support part, thereby saving material usage, reducing weight, and lowering costs. The support part 13 is a hollow cuboid structure, and the support part 13 is fixedly connected to the mounting part 14. A third reinforcing rib 131 is provided at the joint between the mounting part 14 and the support part 13. Multiple mounting parts 14 are provided, preferably two, respectively located at both ends of the support part 13. The mounting part 14 is also a hollow cuboid structure, and several connecting holes (unmarked) are opened at the bottom of the mounting part 14 for threading screws and other connecting parts to fix the mounting part 14 and the buffer assembly 2.

[0040] Reference Figure 4 and Figure 5 The first support plate 21 is a rectangular plate and is fixedly connected to the mounting part 14. The cross-sectional area of ​​the first support plate 21 is larger than that of the mounting part 14. When the device is working, the first support plate 21 will be subjected to external force, which can effectively disperse the stress. In this way, the load-bearing capacity of the electromagnetic chuck mechanism is improved, enabling it to withstand greater pressure and tension. The first support plate 21 and the second support plate 25 are arranged in parallel. The second support plate 25 is also a rectangular plate. The second support plate 25 has several mounting holes (unmarked) for screws and other connecting parts to fix the second support plate 25 and the electromagnetic chuck 3.

[0041] Furthermore, the first support plate 21 is equipped with a plurality of bolts 23, preferably two bolts, which are respectively installed at both ends of the first support plate 21. An isolation block 231 is provided between the bolts 23 and the first support plate 21. The isolation block 231 is used to avoid direct contact between the first support plate 21 and the bolts 23, reduce the wear of the first support plate 21 and the bolts 23, and thus extend the service life of the bolts 23 and the first support plate 21. The bolts 23 pass through the first support plate 21 and the second support plate 25 in sequence and are fixedly connected to the limiting nut 24. A washer 241 is also installed between the limiting nut 24 and the second support plate 25. The spring 22 is sleeved on the bolts 23.

[0042] When the electromagnetic suction mechanism attracts a workpiece, the electromagnetic chuck 3 vibrates upon contact with the workpiece, causing the second support plate 25 connected to the electromagnetic chuck 3 to move relative to it. Since the first support plate 21 and the second support plate 25 are fixed by bolts 23 and limit nuts 24, there is a tendency for the first support plate 21 and the second support plate 25 to move relative to each other. At this time, the spring 23 begins to undergo elastic deformation, achieving a buffering effect. In this way, the buffer assembly 2 reduces the impact and vibration on the electromagnetic suction mechanism during the workpiece attraction process, while protecting the structure of the electromagnetic suction mechanism itself.

[0043] Reference Figure 5 The detection component 4 includes a fixing frame 41 and a detection element 42. The fixing frame 41 is provided with a first connecting block 411 and a second connecting block 412. The first connecting block 411 and the second connecting block 412 are integrally formed. Both the first connecting block 411 and the second connecting block 412 are rectangular plates. The detection element 42 is installed on the first connecting block 411, and the second connecting block 412 is installed on the second support plate 25.

[0044] Furthermore, the detection element 42 is a limit switch. When the electromagnetic suction mechanism moves downward to attract the workpiece to be transported, the limit switch comes into contact with the workpiece. In this way, the limit switch will be triggered to protect the travel and limit of the device, the electromagnetic suction mechanism stops moving downward, and the electromagnetic chuck 3 attracts the workpiece. The detection element 42 is directly obtained from the prior art, so its structure is not specifically described in this application. In some embodiments, the detection element 42 can also be a position sensor.

[0045] Reference Figure 1 This embodiment also includes a control box 5, which is mounted on the support part 13. The control box 5 is equipped with a controller and power supply, etc., for controlling or energizing the electromagnetic chuck 3 and the detection element 42. The controller and power supply in the control box 5 are directly obtained from the prior art, therefore, its structure is not specifically described in this application.

[0046] The working principle of the buffered electromagnetic attraction mechanism in this embodiment is as follows:

[0047] In use, the electromagnetic suction mechanism of this technical solution is installed on the robotic arm of the gripping device. The robotic arm moves above the workpiece to be transported, causing the electromagnetic chuck 3 to move downwards and contact the workpiece to be magnetically attracted. When it moves to a certain position, the detection component 4 is triggered, the electromagnetic suction mechanism stops moving downwards, and then the electromagnetic chuck 3 is energized to attract the workpiece. The robotic arm transports the workpiece to the designated position. After reaching the designated position, the electromagnetic chuck 3 is de-energized, thus completing the transport operation.

[0048] When the electromagnetic chuck adsorbs a workpiece, the buffer component 2 can effectively buffer the impact force generated by the electromagnetic chuck 3 when adsorbing the workpiece, effectively protecting its own structure and reducing damage to the workpiece.

[0049] When the electromagnetic chuck 3 moves above the workpiece, the detection component 4 also starts working to detect whether the falling position is limited, thus protecting the electromagnetic chuck mechanism and the gripping device.

[0050] Another embodiment of this application provides a gripping device, including the buffered electromagnetic suction mechanism in the above embodiments, which grips the workpiece by means of an electromagnetic chuck.

[0051] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
