Description

Technical Field

[0001] The utility model is applied to the technical field of product clamping, and particularly relates to a lifting bidirectional synchronous clamping mechanism. Background Art

[0002] With the continuous development of science and technology, the integration of various electronic products is getting higher and higher. For example, the size of host and server products is getting smaller and smaller, and the integration of products is getting higher and higher. These products are made by installing components of various functions inside the chassis and connecting them through various cables. Due to the large number of wiring harnesses and components integrated in the chassis, it is easy for the connection between components to be unstable during the production and assembly process, resulting in some functions being unable to be realized. Therefore, it is necessary to power on the assembled products and perform various performance tests to ensure that the products meet the factory requirements. After the assembly machine completes the assembly process, the products need to be transported to the testing machine for power-on testing. At present, the assembled products are mainly transported to the testing machine manually, and then the connecting wires and power cords are connected to the products and powered on to realize the testing of various functions. This method has high labor costs and requires manual loading and unloading of the products. During the transportation of the products, it is easy for bumps or vibrations to occur, causing the internal components of the products to loosen. Alternatively, products can be gripped and transferred using an external robot or gripper mechanism. Currently, existing grippers on the market primarily utilize suction cups or traditional grippers. These products require high precision in product placement at the gripping station, are unable to perform secondary positioning, and are prone to vibration during gripping, causing product displacement. Furthermore, the gripping process can easily scratch the product surface. For some specialized switch products, the high density of internal components results in a heavy weight, often exceeding 50 kg. Manual handling of these switch products to the inspection machine is difficult, and traditional robots or grippers are prone to falling off during gripping due to the heavy weight. Consequently, greater pressure is required to prevent the product from falling off. However, excessive pressure can easily deform the thin switch casing, failing to meet factory requirements. A simple, bidirectional, synchronous lifting and gripping mechanism that can coordinate with a loading mechanism to lift and reposition heavy products and achieve precise side-pushing gripping could address these issues.

[0022] like Figures 1 to 7As shown, in this embodiment, the utility model includes a frame 1, a jacking component 2 and a clamping component 3, the jacking component 2 includes a jacking base plate 21, a floating limit module 8 and a jacking support plate 22, the jacking base plate 21 is arranged in the middle of the frame 1, the jacking support plate 22 is matched with the jacking base plate 21 through the floating limit module 8, the lower end surface of the jacking base plate 21 is provided with a jacking cylinder 24, the movable end of the jacking cylinder 24 is matched with the jacking end of the floating limit module 8, the clamping component 3 includes a clamping support plate 31, a clamping connecting plate 32, a rotating motor 33 and a clamping plate module 34, The clamping support plate 31 slides with both sides of the upper end surface of the frame 1 through several first slide rails 35. A clamping cylinder 36 is provided in the middle of the upper end surface of the support plate 31. The movable end of the clamping cylinder 36 is connected to the upper end surface of the clamping connecting plate 32. The clamping plate module 34 is provided on the lower end surface of the clamping connecting plate 32. The movable end of the clamping plate module 34 cooperates with the product 4 on the upper end surface of the jacking support plate 22. The rotating motor 33 is provided at one end of the upper end surface of the clamping connecting plate 32. A rack module 5 is provided on the inner side of the upper end of the frame 1. The movable end of the rotating motor 33 cooperates with the rack module 5. It can be seen that the clamping assembly 3 drives the movement of the clamping module 34 by engaging the rotating motor 33 with the rack module 5. The clamping assembly 3 moves above the product 4. After the floating limit module 8 lifts the product 4 on the lifting support plate 22, the clamping cylinder 36 drives the clamping module 34 to descend and clamp the product 4.

[0023] like Figure 2 and Figure 3As shown, in this embodiment, the clamping plate module 34 includes two sets of sliding plates 341, a clamping cylinder 342, a rotating connecting rod 343 and two sets of clamping plates 344. The two sets of sliding plates 341 are respectively slidably matched with the two ends of the lower end surface of the clamping connecting plate 32 through a plurality of second slide rails 345. The middle part of the rotating connecting rod 343 is rotatably matched with the middle part of the lower end surface of the clamping connecting plate 32. One end of the two sets of transmission connecting rods 346 is respectively hinged to the two ends of the rotating connecting rod 343. The other ends of the two sets of transmission links 346 are respectively hinged to the lower end surfaces of the two sets of sliding plates 341. The clamping cylinder 342 is disposed on the lower end surface of the clamping connecting plate 32. The movable end of the clamping cylinder 342 is connected to the upper end surface of the sliding plate 341 at one end of the lower end surface of the clamping connecting plate 32. The clamping cylinder 342 drives the two sets of clamping plates 344 to move toward each other through the two sets of transmission links 346 and the rotating link 343 to clamp the product 4. Thus, the extension or restoration of the movable end of the clamping cylinder 342 drives the sliding plates 341 to slide on the removal connecting plate 32. The transmission link 346 drives the rotating link 343 to rotate, thereby driving the other set of transmission links 346 to move, thereby achieving synchronous movement of the two sets of sliding plates 341 toward or away from each other, thereby causing the two sets of clamping plates 344 to clamp or release the product 4.

[0024] like Figures 2 to 4 As shown, in this embodiment, a side-pushing adjustment module 6 is provided at the lower end of the clamping plate 344, and the side-pushing adjustment module 6 includes a plurality of side-pushing cylinders 61 and a side-pushing block 62. The side-pushing block 62 is connected to the inner side of the clamping plate 344 through a plurality of first linear bearings 63. A plurality of the side-pushing cylinders 61 are provided on the outer side of the clamping plate 344, and the movable ends of the plurality of side-pushing cylinders 61 are connected to the side-pushing block 62. It can be seen that in the process of the two groups of clamping plates clamping the product 4, the movable ends of the plurality of side-pushing cylinders 61 are pushed out synchronously to make the side-pushing block 62 contact with the outer edge of one side of the product 4 and push for adjustment, so as to achieve the effect of secondary positioning of the product 4 after being lifted, and ensure that the two groups of clamping plates 344 can stably clamp the product 4 and transfer it.

[0025] like Figure 2 and Figure 4 As shown, in this embodiment, the side push block 62 and the other set of clamping plates 344 are both provided with cushioning rubber pads 7 on their contact surfaces with the product 4. Anti-drop hooks 347 are provided at the bottoms of both sets of clamping plates 344. Several of the anti-drop hooks 347 engage with the lower ends of both sides of the product 4. As can be seen, the cushioning rubber pads 7 engage with the sides of the product 4 to prevent scratches on the surface of the product 4 during the clamping process, and the anti-drop hooks 347 prevent the two sets of clamping plates 344 from deviating and falling off during the process of clamping the product 4.

[0026] like Figure 5 and Figure 6 As shown, in this embodiment, the floating limit module 8 includes a floating bottom plate 81, a floating top plate 82 and a plurality of floating cylinders 83. The lifting bottom plate 21 cooperates with the floating top plate 82 through a plurality of second linear bearings 23. The floating bottom plate 81 is connected to the lower end surface of the floating top plate 82 through a plurality of third linear bearings 84. The movable end of the lifting cylinder 24 is connected to the lower end surface of the floating top plate 82. The plurality of floating cylinders 83 are respectively arranged on both sides of the lower end surface of the floating bottom plate 81. The movable ends of the plurality of floating cylinders 83 are respectively connected to both sides of the lower end surface of the floating top plate 82. The clamping support plate 31 is connected to the clamping connecting plate 32 through a plurality of fourth linear bearings 37. It can be seen that the lifting cylinder 24 drives the floating limit module 8 to rise as a whole, so that the lifting support plate 22 can rise or fall, thereby realizing the height adjustment of the product 4. The movable ends of several floating cylinders 83 drive the floating bottom plate 81 and the floating top plate 82 to move relative to each other, so that several limit ends on the floating limit module 8 pass through the lifting support plate 22 and cooperate with the product 4.

[0027] like Figure 5 and Figure 6 As shown, in this embodiment, the upper end surface of the floating bottom plate 81 is provided with a plurality of limiting posts 85. The floating top plate 82 and the lifting support plate 22 are respectively provided with a plurality of first limiting holes 9 and a plurality of second limiting holes 10 that are compatible with the limiting posts 85. The floating cylinders 83 drive the floating bottom plate 81 upward, so that the limiting posts 85 pass through the plurality of first limiting holes 9 and the plurality of second limiting holes 10 to engage with the product 4 on the lifting support plate 22. The contact surfaces of the limiting posts 85 and the product 4 are provided with a non-slip rubber layer. It can be seen that the movable ends of the floating cylinders 83 drive the relative movement of the floating bottom plate 81 and the floating top plate 82. The limiting posts 85 extend from the plurality of first limiting holes 9 and pass through the plurality of limiting holes 10 to contact the bottom of the product 4, separating the product 4 from the lifting support plate 22, ensuring that the two sets of clamping plates 344 can stably clamp the product 4.

[0028] like Figure 6 As shown, in this embodiment, the upper end surface of the floating roof plate 82 is further provided with a plurality of stop pins 86, and the stop pins 86 cooperate with the stop holes on the lifting support plate 22. It can be seen that when the lifting cylinder 24 lifts the floating roof plate 82 upward, the floating roof plate 82 contacts the lifting support plate 22, and the stop pins 86 cooperate with the stop holes to prevent deviation during the lifting process.

[0029] like Figure 7As shown, in this embodiment, the rack module 5 includes a rack 51 and a rack connecting plate 52. The rack 51 is arranged on the inner side of the upper end of the frame 1 through the rack connecting plate 52. The rotary motor 33 is arranged at the end of the gripping connecting plate 32 corresponding to the rack 51. The movable end of the rotary motor 33 is provided with a rotary gear 11, which meshes with the rack 51. As can be seen, the rotary motor 33 drives the rotary gear 11 to rotate, and the rotary gear 11 cooperates with the rack 51, causing the gripping assembly 3 to slide as a whole on the upper end of the frame 1 to perform gripping and transfer.

[0030] like Figure 3 As shown, in this embodiment, the lower end surface of the clamping connecting plate 32 is provided with a plurality of buffers 12, and the plurality of buffers 12 respectively cooperate with the two sets of sliding plates 341. Thus, the plurality of buffers 12 ensures that the force applied by the two sets of clamping plates 344 during the process of clamping the product 4 is more uniform, thereby preventing overpressure on the product 4.

[0031] like Figure 1 and Figure 6 As shown, in this embodiment, a plurality of guide blocks 12 and stop bars 13 are provided on one side of the lifting support plate 22. The guide blocks 12 and stop bars 13 respectively cooperate with the products 4. It can be seen that after the loading mechanism loads the product, the guide blocks 12 serve as guides to complete the initial positioning, and the stop bars 13 prevent the product 4 from sliding off the edge of the lifting support plate 22.

[0032] The working principle of the present invention is as follows: the external loading mechanism places the product 4 on the lifting support plate 22, and several of the guide blocks 12 perform preliminary positioning on the product 4. The rotating motor 33 drives the rotating gear 11 to rotate and cooperate with the rack 51, so that the clamping assembly 3 slides on the frame 1 to the upper end of the product 4, and the lifting cylinder 24 drives the floating top plate 82 to rise, so that the lifting support plate 22 rises synchronously, and several of the floating cylinders 83 drive the floating bottom plate 81 to rise, and several of the limiting columns 85 pass through several of the first limiting through holes 9 and several of the second limiting through holes 10 and contact the lower end surface of the product 4, and separate the product 4 from the lifting support plate 22. The cylinder 36 drives the clamping plate module 34 to descend, and the clamping cylinder 342 drives the two groups of the clamping plates 344 to approach each other to clamp the product 4. Several of the side push cylinders 61 drive the side push blocks 62 to extend, and the side push blocks 62 contact one side of the product 4 and adjust the position of the product 4 for secondary positioning. After positioning is completed, the two groups of the clamping plates 344 clamp the product 4, and drive the product 4 to be transferred to the inspection station through the rotating motor 33 and the clamping cylinder 342, and perform docking power-on detection. After the detection is completed, the product 4 is placed on the unloading end of the jacking support plate 22, transferred through the unloading mechanism, and then the product 4 to be tested is placed. Repeat the above steps to realize automatic jacking, positioning, clamping and detection.

[0033] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
