Description

Technical Field

[0001] This invention relates to the field of clamping equipment technology, specifically to an adaptive clamping device and method for convex corner elements. Background Technology

[0002] In today's industrial manufacturing field, irregularly shaped components play an important role in various products due to their unique structure and performance. Among them, irregularly shaped components with protruding corners are particularly difficult to handle during the production process due to their design complexity. Traditional transfer methods, such as adsorption or lateral clamping, often fail to meet the stability and safety requirements of these components.

[0003] While existing adsorption-transfer technologies can handle irregularly shaped components to some extent, achieving a uniform distribution of adsorption force remains a challenge for components with protruding corners. Protruding corners can easily cause uneven adsorption force, leading to component vibration or even detachment during transport. This not only affects component precision but can also cause production line shutdowns and component damage.

[0004] While lateral clamping and transfer technology can provide a certain degree of stability, the clamping force is concentrated on the side of the component, and the protruding corners often bear greater pressure, making the component highly susceptible to deformation or damage. This damage not only affects the component's appearance but, more seriously, can alter its dimensions and performance, thus impacting the overall product quality and functionality. Furthermore, lateral clamping provides insufficient stability in high-speed operation or high-vibration environments, making it prone to slippage and increasing risks during production.

[0005] Therefore, existing technologies have significant limitations in addressing the transportation of irregularly shaped components with protruding corners. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem of low stability of components with convex corners during transportation in the prior art, and to provide an adaptive clamping device and method.

[0007] To address the aforementioned technical problems, this invention provides an adaptive clamping device for convex corner components, comprising: a support mechanism including a base tray and at least two surrounding edges, the base tray having a clearance portion, the at least two surrounding edges being disposed at the edges of the base tray, a component to be clamped being supported on the base tray with its edge abutting against the surrounding edges, and at least one corner of the component to be clamped being exposed outside the base tray through the clearance portion; at least one compression fixing mechanism, the at least one compression fixing mechanism being disposed corresponding to at least one clearance portion, each compression fixing mechanism comprising: a drive assembly connected to the base tray; a moving assembly that moves closer to / away from the clearance portion via the drive assembly, the moving assembly comprising a base plate and two pushers, one side of the base plate being slidably connected to the drive assembly, and the other side being connected to the two pushers, the two pushers extending along the thickness direction of the base plate and located on both sides of the corner of the component to be clamped, so as to compress / release the corner of the component to be clamped during movement.

[0008] In one embodiment of the present invention, at least two of the surrounding edge connections are provided with corner clearance grooves, and other corners of the element to be clamped are inserted into the corner clearance grooves.

[0009] In one embodiment of the present invention, the driving component includes a sliding plate and at least one slide groove, and the base plate is provided with at least one slider, which is embedded in the corresponding slide groove and moves along the slide groove.

[0010] In one embodiment of the present invention, the drive assembly further includes a stop block connected to the slide plate and extending into the movement path of the moving assembly, wherein the bearing mechanism and the stop block are respectively disposed on opposite sides of the slide plate.

[0011] In one embodiment of the present invention, the drive assembly further includes a first pneumatic interface and a second pneumatic interface, the first pneumatic interface and the second pneumatic interface being respectively disposed on opposite sides of the slide plate along the moving direction of the moving assembly, and respectively connected to an external gas compression device.

[0012] In one embodiment of the present invention, the moving component further includes a first assembly, the pushing member being connected to the base plate via the first assembly, the first assembly including a platform, a fixing plate and two positioning pins, one side of the platform being connected to the base plate and moving synchronously with the base plate, the fixing plate being connected to the platform, the two positioning pins being disposed on the fixing plate and extending along the thickness direction of the fixing plate respectively, and the two pushing members being respectively inserted into the two positioning pins.

[0013] In one embodiment of the present invention, the compression fixing mechanism further includes at least one guide rod, which is fixed to the moving component and slidably passes through the driving component.

[0014] In one embodiment of the present invention, the guide rod includes a fixing part, a guiding part, and a limiting part connected in sequence, wherein the limiting part is fixed to the moving component and its cross-sectional diameter is larger than that of the guiding part.

[0015] In one embodiment of the present invention, the movable component further includes a second fitting, the second fitting having at least one insert groove inside, the edge of the insert groove being configured as a stepped surface, and the limiting portion abutting against the stepped surface.

[0016] The present invention also provides an adaptive clamping method for convex corner components, which uses the above-mentioned adaptive clamping device for convex corner components to clamp and fix components with convex corners. The method includes the following steps: Step S1, with the bearing mechanism and the pressing and fixing mechanism relatively far apart, the component to be clamped is placed on the bottom tray of the bearing mechanism, so that the edge of the component to be clamped faces the perimeter of the bearing mechanism, and at least one corner of the component to be clamped is exposed outside the bottom tray; Step S2, the pressing and fixing mechanism is driven to move toward the bearing mechanism, so that the two pushing members push the corner of the component to be clamped from both sides of the corner of the component to be clamped, until the component to be clamped is pressed and fixed between the perimeter and the pushing members.

Compared with conventional clamping devices, this application has significant advantages such as wide applicability, flexible adjustment, strong compatibility, ease of operation, avoidance of clamping damage, and stable and efficient clamping action, and has broad application prospects in the industry.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0027] Example 1

[0028] See Figure 1As shown, this embodiment provides an adaptive clamping device for convex corner components, comprising: a support mechanism 100, the support mechanism 100 including a base tray 110 and at least two surrounding edges 120, the base tray 110 having a clearance portion 130, the at least two surrounding edges 120 being disposed at the edges of the base tray 110, a component 300 to be clamped being supported on the base tray 110, its edge abutting against the surrounding edges 120, and at least one corner of the component 300 to be clamped being exposed outside the base tray 110 through the clearance portion 130; and at least one compression fixing mechanism 200, the at least one compression fixing mechanism 200 corresponding to at least one of the clearance portions. 130 configuration, wherein any of the compression fixing mechanisms 200 includes: a drive assembly 210 connected to the bottom tray 110; and a moving assembly 220 that moves toward / away from the clearance portion 130 via the drive assembly 210. The moving assembly 220 includes a base plate 221 and two pushers 225. One side of the base plate 221 is slidably connected to the drive assembly 210, and the other side is connected to the two pushers 225. The two pushers 225 extend along the thickness direction of the base plate 221 and are located on both sides of the corner of the element to be clamped 300, so as to squeeze / release the corner of the element to be clamped 300 during movement.

[0029] The adaptive clamping device for convex corner components described in this embodiment uses a supporting mechanism 100 to support and lift the component 300 to be clamped. Simultaneously, its surrounding edge 120 limits and stops the edge of the component 300. Then, a pressing and fixing mechanism 200 achieves adaptive adjustment and limiting of the component without damaging its corners. This process not only improves the stability of the component during clamping and fixing but also completely avoids crushing damage to the component's corners when force is applied. Compared to conventional clamping devices, this application has significant advantages such as wide applicability, flexible adjustment, strong compatibility, ease of operation, avoidance of clamping damage, and stable and efficient clamping action, and has broad application prospects in the industry.

[0030] See Figure 1 As shown, the convex corner element adaptive clamping device in this embodiment is used to clamp rectangular sheet-like elements. It includes a pressing and fixing mechanism 200, which is connected below the supporting mechanism 100 to push against both sides of the corner of the element 300 to be clamped. In different embodiments, the supporting mechanism 100 can be set to different shapes according to the actual shape of the element, and the pressing and fixing mechanism 200 can also be set to other numbers. The present invention does not impose specific limitations on this.

[0031] See Figure 2As shown, in this embodiment, the bottom tray 110 has a clearance portion 130 on one side. The clearance portion 130 provides movement space for the compression fixing mechanism 200 to ensure that the compression fixing mechanism 200 can clamp and compress the two sides of the corner of the component 300 to be clamped. In this embodiment, the tray can provide an installation platform for the edge 120 and the compression fixing mechanism 200, and can also form a support for the component 300 to be clamped, thereby further improving the clamping stability. Based on this, the compression fixing mechanism 200 in this application only needs to achieve lateral limiting of the component, without applying excessive compression clamping force to the component. Therefore, compared with conventional lateral clamping, suction cup adsorption and other structures, this application can minimize the possibility of clamping damage to the component.

[0032] In this embodiment, the perimeter 120 protrudes vertically upward from the top surface of the bottom tray 110 to stop and limit the edge of the component to be clamped. Furthermore, in this embodiment, at least two of the perimeters 120 are connected by corner clearance grooves 121, into which other corners of the component to be clamped 300 are inserted. Since the component to be clamped 300 in this application is a rectangular sheet-like component, its corners located at the connections of the perimeters 120 are also at risk of damage during the pushing process. Simultaneously, to reduce the number of pressing and fixing mechanisms 200 and thus reduce the overall size of the equipment, this application can disperse the stress at the corners of the component to be processed by providing corner clearance grooves 121.

[0033] See Figure 3 As shown, the compression fixing mechanism 200 in this embodiment is used to push and compress the corner of the component to be clamped exposed by the avoidance part 130. The drive assembly 210 connects the moving assembly 220 and the carrying mechanism 100, and also provides driving force to the moving assembly 220 via an external air compressor. The moving assembly 220 applies pushing and compressing force to the corner of the component to be processed via the pusher 225 connected to it. Further, see... Figure 4 As shown, the drive assembly 210 includes a sliding plate 211 and at least one slide groove 212. At least one slider 222 is provided on the base plate 221, and the slider 222 is embedded in the corresponding slide groove 212 and moves along the slide groove 212. Further, the drive assembly 210 also includes a first pneumatic interface 213 and a second pneumatic interface 214. The first pneumatic interface 213 and the second pneumatic interface 214 are respectively disposed on opposite sides of the sliding plate 211 along the moving direction of the moving assembly 220, and are respectively connected to external gas compression devices. This application enables the pushing movement of the moving assembly 220 by opening two pneumatic interfaces.

[0034] Furthermore, the drive assembly 210 in this embodiment also includes a stop block 215, which is connected to the slide plate 211 and extends into the movement path of the moving assembly 220. The bearing mechanism 100 and the stop block 215 are respectively disposed on opposite sides of the slide plate 211 to limit the movement distance of the moving assembly 220. To further reduce the size of the device, the first pneumatic interface 213 in this embodiment is disposed on the stop block 215.

[0035] See Figure 5 As shown, the moving component 220 further includes a first assembly 223. The pushing member 225 is connected to the base plate 221 through the first assembly 223. The first assembly 223 includes a platform 2231, a fixing plate 2233, and two positioning pins 2232. One side of the platform 2231 is connected to the base plate 221 and moves synchronously with the base plate 221. The fixing plate 2233 is connected to the platform 2231. The two positioning pins 2232 are disposed on the fixing plate 2233 and extend along the thickness direction of the fixing plate 2233. The two pushing members 225 are respectively inserted into the two positioning pins 2232. In this embodiment, the platform 2231 is preferably a rectangular block element. The positioning pin 2232 is fixed to the top surface of the platform 2231 by the connector 2234. The two positioning pins 2232 are fixedly connected to the platform 2231 and are respectively provided with fixing plates 2233 so as to contact the pusher 225. The pusher 225 is inserted into the corresponding positioning pin 2232.

[0036] See Figure 5 As shown, to further improve the stability of the moving component 220 during movement, the compression fixing mechanism 200 in this embodiment further includes at least one guide rod 230, which is fixedly connected to the moving component 220 and slidably passes through the drive component 210. Further, the guide rod 230 includes a fixing part 231, a guiding part 232, and a limiting part 233 connected in sequence, wherein the limiting part 233 is fixedly connected to the moving component 220, and its cross-sectional diameter is larger than that of the guiding part 232. In this embodiment, the moving component 220 also includes a second mounting part 224, which has at least one embedding groove 2241 inside. The edge of the embedding groove 2241 is configured as a stepped surface, and the limiting part 233 abuts against the stepped surface, thereby achieving limiting in the moving direction of the moving component 220.

[0037] Example 2

[0038] This embodiment provides an adaptive clamping method for convex corner components, which uses the adaptive clamping device for convex corner components described in Embodiment 1 to clamp and fix components with convex corners, and includes the following steps:

[0039] Step S1: With the support mechanism 100 and the compression fixing mechanism 200 relatively far apart, place the component to be clamped 300 on the bottom tray 110 of the support mechanism 100, so that the edge of the component to be clamped 300 faces the perimeter 120 of the support mechanism 100, and at the same time expose at least one corner of the component to be clamped 300 to the outside of the bottom tray 110.

[0040] Step S2: Drive the compression fixing mechanism 200 to move toward the bearing mechanism 100, so that the two pushers 225 push the corner of the element to be clamped 300 from both sides of the corner of the element to be clamped 300, until the element to be clamped 300 is compressed and fixed between the perimeter 120 and the pushers 225.

[0041] In summary, the adaptive clamping device and method for convex corner components described in this invention uses a supporting mechanism 100 to support and lift the component 300 to be clamped, while its surrounding edge 120 limits and stops the edge of the component 300. Then, a pressing and fixing mechanism 200 achieves adaptive adjustment and limiting of the component without damaging its corners. This process not only improves the stability of the component during clamping and fixing but also completely avoids the possibility of crushing damage to the component's corners when force is applied. Compared to conventional clamping devices, this application has significant advantages such as wide applicability, flexible adjustment, strong compatibility, ease of operation, avoidance of clamping damage, and stable and efficient clamping action, and has broad application prospects in the industry.
