Description

Technical Field

[0001] This application relates to the field of clamping mechanisms, and particularly to a clamping mechanism and a transfer device. Background Technology

[0002] During the workpiece clamping and unloading process, ensuring the workpiece is held horizontally is crucial for smooth subsequent processes. If the workpiece's reference surface deviates from the horizontal plane after clamping, it means the workpiece is tilted. This uneven clamping can cause the robotic arm to be unable to accurately place the workpiece at the next station during unloading on an automated production line, potentially leading to malfunctions such as jamming, dropping, or equipment collisions.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0038] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0039] It should be understood that the term "and / or" as used in this application specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] Please see Figure 1 This application provides a clamping mechanism 100, which includes a mounting member 10, a clamping device 20, and a level detection device 30. The clamping device 20 is disposed on the mounting member 10 and is used to clamp a workpiece. The level detection device 30 is disposed on the mounting member 10 and aligned with the surface to be measured of the workpiece. The level detection device 30 is used to detect the levelness of the surface to be measured of the workpiece clamped by the clamping device 20.

[0042] Mounting component 10 serves as the basic support structure of clamping mechanism 100, and its shape and structure can be designed according to the actual application scenario. For example, mounting component 10 can be a plate, in the form of a rectangle, circle or other irregular shape. Mounting component 10 can be pre-set with multiple sets of mounting holes or guide rail grooves for mounting clamping device 20 and horizontal detection device 30, and allows their positions to be finely adjusted within a certain range to adapt to workpieces of different sizes.

[0043] The clamping device 20 is disposed on one side of the mounting member 10 and can be connected to the mounting hole of the mounting member 10 by bolts. In one embodiment, the clamping device 20 can be one or more pairs of opposing mechanical clamps. The mechanical clamps specifically include a cylinder, a first clamping arm, and a second clamping arm. The cylinder body is fixed to the mounting member 10 by bolts, and the movable end of the cylinder is connected to the first clamping arm and the second clamping arm to drive the first clamping arm and the second clamping arm to open and close, thereby completing the clamping of the workpiece. The contact surfaces between the first clamping arm and the second clamping arm and the workpiece can be provided with a flexible material to reduce damage to the workpiece during clamping.

[0044] In another embodiment, the clamping device 20 can also be a vacuum adsorption assembly. For example, multiple vacuum suction cups can be arrayed on the mounting member 10 to adsorb the workpiece. Vacuum adsorption avoids deformation or indentation caused by mechanical clamping to sheet metal workpieces.

[0045] A level detection device 30 is also mounted on the mounting component 10. The detection axis or detection surface of the level detection device 30 is aligned with the surface to be measured when the workpiece is clamped. The level detection device 30 is used to detect the levelness of the surface to be measured of the workpiece. If the levelness meets the preset requirements, the next process can proceed. If it does not meet the requirements, the clamping device 20 releases the workpiece, adjusts it, and then re-clamps it until the levelness meets the preset requirements.

[0046] It should be noted that the surface to be measured refers to a specific surface on the workpiece that can be used for levelness inspection. When the levelness of a surface of the workpiece meets the preset requirements and the workpiece is in a level state, that surface is usually selected as the surface to be measured. The shape of the surface to be measured can be flexibly varied according to the type of workpiece; it can be a flat plane, or a curved surface or stepped surface with specific requirements.

[0047] The level detection device 30 may include, but is not limited to, an electronic level, an inclination sensor, a bubble level, or a laser level. The appropriate type of level detection device 30 can be selected according to different needs, and there are no restrictions here.

[0048] In the clamping mechanism 100 of this application, after the clamping device 20 clamps the workpiece, the horizontality of the surface to be measured of the workpiece is detected by the horizontality detection device 30, thereby determining whether the workpiece is clamped horizontally and avoiding difficulties in unloading the workpiece due to uneven clamping. Furthermore, by integrating the clamping device 20 and the horizontality detection device 30 onto the mounting component 10, integrated operation of workpiece clamping and horizontality detection is achieved, eliminating the need to transfer the workpiece to a dedicated testing device after clamping, thus improving work efficiency.

[0049] Please see Figure 1 and Figure 2 Optionally, the horizontal detection device 30 includes a sensor 31 and a probe assembly 32. The sensor 31 is connected to the mounting member 10, and the probe assembly 32 is movably disposed on the mounting member 10 and located between the sensor 31 and the workpiece.

[0050] When the clamping device 20 clamps the workpiece, the surface to be measured on the workpiece pushes the probe assembly 32 toward the sensor 31 until the probe assembly 32 contacts the sensor 31. In this way, by converting the movement generated by the surface to be measured pushing the probe assembly 32 into a physical contact signal that can be recognized by the sensor 31, the levelness of the surface to be measured is detected.

[0051] Specifically, the probe assembly 32 can be movably mounted on the mounting part 10 through a guide mechanism such as a linear guide sleeve, slide rail or precision shaft hole fit, and the guide mechanism ensures that the probe assembly 32 can reciprocate in a direction perpendicular to the horizontal plane.

[0052] When the clamping device 20 clamps the workpiece, the workpiece is pushed to a predetermined clamping position, causing the surface to be measured on the workpiece to come into contact with the contact head of the probe assembly 32. The clamping device 20 continuously applies pressure, thereby pushing the entire probe assembly 32 along the guide mechanism toward the sensor 31 until it contacts the sensor 31. When the clamping device 20 clamps the workpiece, the workpiece can simultaneously trigger the operation of the horizontal detection device 30. The clamping mechanism 100 can perform horizontal detection while clamping the workpiece, improving work efficiency.

[0053] Sensor 31 detects the levelness of the surface to be measured by detecting the state of probe assembly 32. If the surface to be measured is parallel to the horizontal plane, it will push probe assembly 32 with a uniform force, causing probe assembly 32 to contact sensor 31 in a flat position. If the surface to be measured is not parallel to the horizontal plane, it will push probe assembly 32 with a non-uniform force, which may cause slight deflection or jamming of probe assembly 32 during movement, preventing it from contacting sensor 31 in the correct position, such as point contact or line contact.

[0054] Please see Figures 1-3Optionally, the mounting component 10 includes a mounting plate 11, a connecting seat 12, and a guide sleeve 13. The clamping device 20 is disposed on the mounting plate 11, the connecting seat 12 is connected to the mounting plate 11, a sensor 31 is disposed on the connecting seat 12, and the guide sleeve 13 passes through the connecting seat 12.

[0055] The probe assembly 32 includes a probe 321 and a first elastic element 322. The probe 321 passes vertically through the guide sleeve 13, and both ends of the probe 321 protrude from the guide sleeve 13. The first elastic element 322 is sleeved on the probe 321 and housed within the guide sleeve 13.

[0056] When the clamping device 20 clamps the workpiece, the surface to be measured pushes the probe 321 to move vertically toward the sensor 31 until the probe 321 contacts the sensor 31. In this way, the cooperation structure between the guide sleeve 13 and the probe 321 ensures that the probe 321 can only move in the preset vertical direction, effectively avoiding measurement errors caused by lateral swaying or tilting.

[0057] Specifically, the connecting base 12 can be an L-shaped plate, which includes a horizontal plate and a vertical plate that are connected to each other. The vertical plate is connected to the mounting plate 11, and the horizontal plate is used to mount the sensor 31 and the probe assembly 32.

[0058] The guide sleeve 13 is inserted into and fixed in a pre-set through hole on the connecting seat 12. The main body of the probe 321 is slidably inserted into the inner hole of the guide sleeve 13 in a vertical direction, and both ends of the probe 321 protrude from the openings at both ends of the guide sleeve 13.

[0059] The lower end of the probe 321 is used to contact the surface of the workpiece to be measured, and the upper end is used to trigger the sensor 31. The first elastic element 322 can be a compression spring, which is sleeved on the probe 321 and housed in the inner cavity of the guide sleeve 13. One end of the first elastic element 322 abuts against the stepped surface of the inner wall of the guide sleeve 13, and the other end abuts against the shoulder provided on the probe 321.

[0060] In its natural state, the preload of the first elastic element 322 keeps the probe 321 in an initial position, at which point the lower end of the probe 321 protrudes a certain distance from the lower end of the guide sleeve 13 to facilitate contact with the workpiece. When the clamping device 20 clamps the workpiece, the surface to be measured on the workpiece moves upward and contacts the lower end of the probe 321. As the clamping action continues, the surface to be measured pushes the probe 321, overcoming the elastic force of the first elastic element 322, thereby pushing the probe 321 to move vertically towards the sensor 31 under the guidance of the guide sleeve 13.

[0061] The probe 321 continues to move upward until its upper end contacts the sensor 31 fixed on the connecting seat 12. If the surface to be tested is level, the upper end of the probe 321 will trigger the sensor 31 in the preset correct posture. If the surface to be tested is not level, an uneven lateral force will be applied to the probe 321, causing the probe 321 to tilt to a certain extent within the guide sleeve 13. This prevents the upper end of the probe 321 from contacting the sensor 31 in the preset correct posture. This abnormal signal is detected by the sensor 31, thus determining that the levelness of the surface to be tested is unqualified.

[0062] After the clamping mechanism 100 releases the workpiece, the workpiece is no longer holding the probe 321. Under the restoring force of the first elastic element 322, the probe 321 moves downward along the guide sleeve 13 and automatically resets to the initial position to facilitate the next horizontal inspection.

[0063] Optionally, the probe assembly 32 also includes a sensing plate 323, which is disposed at the end of the probe 321 near the sensor 31. The cross-sectional area of ​​the sensing plate 323 is larger than that of the probe 321. The sensing plate 323 provides the sensor 31 with a larger and flatter sensing surface, ensuring that the sensor 31 can capture the detection signal more effectively and stably, making the detection results more reliable.

[0064] The sensing element 323 can be a circular thin sheet and is disposed on the upper end of the probe 321 by means of threaded connection or bonding. When the surface to be measured pushes the probe 321, causing the probe 321 to move along the guide sleeve 13 towards the sensor 31, the sensing element 323 moves synchronously. The sensor 31 detects the change in the position or state of the sensing element 323, thereby realizing the detection of the levelness of the surface to be measured.

[0065] Optionally, the clamping mechanism 100 further includes a first movable module (not shown) disposed on the mounting member 10, the first movable module being connected to the horizontal detection device 30 to drive the horizontal detection device 30 to move horizontally relative to the mounting member 10.

[0066] In this way, the position of the horizontal detection device 30 can be adjusted according to the size of different workpieces or the position of the surface to be measured. When it is necessary to detect workpieces of different specifications, the horizontal detection device 30 is moved by the first moving module, so that the probe assembly 32 can be accurately aligned with the surface to be measured of the current workpiece. There is no need to readjust the position of the entire clamping mechanism 100 for each type of workpiece, which improves the overall adaptability of the clamping mechanism 100.

[0067] Specifically, the first moving module is mounted on the mounting member 10. The fixed part of the first moving module is connected to the mounting member 10, and the driving part is connected to the horizontal detection device 30. The driving part of the first moving module is used to drive the entire horizontal detection device 30 to move horizontally relative to the mounting member 10. The first moving module can be an electric linear slide, a cylinder-driven slide rail assembly, or a lead screw and nut mechanism, etc., and is not limited here.

[0068] Please see Figure 1 Optionally, the clamping mechanism 100 includes a pressure bar assembly 40, which includes a pressure bar 41. The pressure bar 41 is disposed on the mounting member 10 and extends vertically toward the workpiece. The pressure bar 41 is used to clamp the workpiece.

[0069] Thus, before and during clamping, the workpiece is held in a state by the pressure bar 41, preventing it from moving and thereby improving the stability of the workpiece during horizontal inspection or processing, and further improving the accuracy of horizontality inspection.

[0070] The pressure rod 41 extends vertically downward from the mounting part 10. The lower end of the pressure rod 41 is provided with a pressure head, which can be made of a wear-resistant material with moderate hardness to ensure that the workpiece is effectively pressed while reducing damage to the workpiece surface.

[0071] The number of pressure bars 41 can be multiple, and the multiple pressure bars 41 are spaced apart on the mounting part 10 to further ensure the stability of the workpiece. The length and diameter of the multiple pressure bars 41 can be the same or different, depending on the specific shape of the workpiece.

[0072] Please see Figure 1 and Figure 4 Optionally, the pressure bar assembly 40 further includes a buffer assembly 42, which includes a cover plate 421, a guide member 422, and a second elastic member 423. The guide member 422 is connected to the cover plate 421 and the mounting member 10. The cover plate 421 is located on the side of the mounting member 10 away from the pressure bar 41. The second elastic member 423 is sleeved on the guide member 422 and disposed between the cover plate 421 and the mounting member 10.

[0073] Thus, the rigid clamping of the pressure bar 41 on the workpiece is converted into elastic clamping by the buffer assembly 42, so that the pressure bar assembly 40 has a buffering function, which can adapt to the slight unevenness or thickness change of the workpiece surface, provide a stable clamping force, and effectively protect the workpiece surface.

[0074] The guide member 422 can be a guide post, and there are multiple guide members 422 spaced apart. One end of the guide member 422 is connected to the mounting member 10, and the other end passes through a corresponding through hole on the cover plate 421 and can slide axially along the through hole, thereby movably connecting the cover plate 421 and the mounting member 10. The number of second elastic members 423 corresponds one-to-one with the number of guide posts, and each second elastic member 423 is sleeved on a guide post. The second elastic member 423 can be a compression spring.

[0075] When the pressure rod 41 contacts the workpiece surface and is continuously pressed, it transmits the pressure to the mounting member 10, thereby pushing the mounting member 10 to move axially relative to the cover plate 421 along the guide member 422, while simultaneously compressing the second elastic member 423. The rebound force generated by the compression of the second elastic member 423 provides a buffer for the clamping force applied to the workpiece by the pressure rod 41, thereby reducing the impact and preventing damage to the workpiece surface or displacement of the workpiece. When the clamping force is released, the mounting member 10 returns to its initial position along the guide member 422 under the restoring force of the second elastic member 423.

[0076] Please see Figure 1 and Figure 4 Optionally, the clamping device 20 includes a mounting base 21, a driving member 22, and a gripper 23. The mounting base 21 is provided with the driving member 22 and the gripper 23, and the driving member 22 drives the gripper 23 to move to clamp the workpiece. The mounting member 10 has a plurality of mounting positions along its circumference, and the mounting base 21 is detachably connected to the mounting member 10 so that the mounting base 21 is mounted on any of the mounting positions.

[0077] This allows for quick changes in the mounting position of the clamping device 20 on the mounting member 10 according to workpieces of different shapes and sizes, thereby improving the flexibility of the clamping mechanism 100.

[0078] The drive component 22 can be a cylinder, hydraulic cylinder, or electric push rod, etc. The fixed part of the drive component 22 is mounted on the mounting base 21, and the movable part of the drive component 22 is connected to the gripper 23 to control the movement of the gripper 23 to clamp or release the workpiece.

[0079] There are multiple mounting positions. The mounting base 21 can be set in the corresponding mounting position according to the size and shape of the workpiece, so that the gripper can better hold the workpiece. The mounting position can be a mounting hole formed on the mounting part 10, and the mounting base 21 is threadedly connected to the mounting hole by bolts.

[0080] Optionally, there may be multiple clamping devices 20, which are arranged circumferentially along the mounting member 10 to achieve stable clamping of the workpiece. The number of mounting positions is greater than or equal to the number of clamping devices 20.

[0081] The clamping device 20 may further include a guide rod 24 and a third elastic element 25 to achieve a buffering function. The guide rod 24 is arranged vertically, with its upper end passing through a corresponding guide hole on the mounting base 21 and sliding axially along the guide hole. Its lower end extends towards the workpiece and connects to the gripper 23. The third elastic element 25 can be a compression spring, sleeved on the guide rod 24, with its two ends abutting against the lower surface of the mounting base 21 and the limiting portion on the gripper 23, respectively. When the gripper 23 contacts the workpiece, the gripper 23 can move axially along the guide rod 24, while simultaneously compressing the third elastic element 25, thereby preventing a rigid collision between the gripper 23 and the workpiece.

[0082] Optionally, the clamping mechanism 100 further includes a second movable module (not shown) disposed on the mounting member 10, the second movable module being connected to the clamping device 20 to drive the clamping device 20 to move horizontally relative to the mounting member 10.

[0083] In this way, the position of the clamping device 20 on the mounting part 10 can be adjusted according to the size of different workpieces, thereby improving the overall adaptability of the clamping mechanism 100. The specific working principle of the second moving module is the same as or similar to that of the first moving module, except that the driven components are different. For details, please refer to the first moving module, which will not be repeated here.

[0084] Please see Figure 1 and Figure 4 Optionally, the clamping mechanism 100 includes a positioning pin 50, which is disposed on the mounting member 10 and extends vertically toward the workpiece. The positioning pin 50 is used to insert into the positioning hole of the workpiece.

[0085] The size of the locating pin 50 is adapted to the preset locating hole on the workpiece. During the clamping process, when the workpiece is moved to the clamping station, the locating hole on the workpiece is first roughly aligned with the locating pin 50. As the clamping device 20 moves towards the workpiece, the locating pin 50 is gradually inserted into the locating hole of the workpiece, achieving precise positioning of the workpiece.

[0086] This application also provides a transfer device, including a multi-dimensional drive mechanism and a clamping mechanism 100 as described in any of the above embodiments. The multi-dimensional drive mechanism is connected to the mounting member 10 of the clamping mechanism 100 to drive the mounting member 10 to move in multiple directions. The transfer device of this application uses the clamping mechanism 100 described above, and therefore has at least the beneficial effects of the clamping mechanism 100 described above, which will not be repeated here.

[0087] The above are merely preferred embodiments of this application and do not limit the scope of the patent application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of this application.
