Description

Technical Field

[0001] The invention relates to the technical field of fastening equipment, and in particular to a vacuum matrix suction cup device. Background Art

[0002] Vacuum suction cups, also known as vacuum slings, are one of the actuators of vacuum equipment. Generally speaking, using vacuum suction cups to grab products is the cheapest method. There are many types of vacuum suction cups. Suction cups made of rubber can be operated at high temperatures, suction cups made of silicone rubber are very suitable for grabbing products with rough surfaces; suction cups made of polyurethane are very durable. In addition, in actual production, if the suction cup is required to be oil-resistant, you can consider using materials such as polyurethane, nitrile rubber or vinyl-containing polymers to make the suction cup. Usually, in order to avoid scratches on the surface of the product, it is best to choose a suction cup with a bellows made of nitrile rubber or silicone rubber. The material is made of nitrile rubber, which has a large tearing force and is therefore widely used in various vacuum holding equipment.

[0032] like Figure 1 - Figure 4 and Figure 8 As shown, the bonding component 10 includes a bonding plate 15 and a first connecting rod 16, the first connecting rod 16 is fixedly connected to the middle part of the partition plate 11, the bonding plate 15 is fixedly connected to the end of the first connecting rod 16 away from the partition plate 11, and the bonding plate 15 is arranged parallel to the partition plate 11, the bottom of the rotating rod 20 is partially sleeved inside the first connecting rod 16, the inner wall of the first connecting rod 16 is provided with a spiral groove 25, and the outer end face of the rotating rod 20 is provided with a driving slider adapted to the spiral groove 25.

[0033] Furthermore, a limiting sliding block is provided on the side end surface of the partition plate 11 , and the partition plate 11 is slidably connected inside the sliding cavity 12 .

[0034] When in use, the first connecting rod 16 is fixedly connected to the partition plate 11, and the bonding plate 15 is arranged parallel to the partition plate 11. The bonding plate 15 is bonded to the bonding surface 29 as the suction cup device 1 moves downward, and as the curvature of the bonding surface 29 deflects, the partition plate 11 is driven to deflect through the bonding plate 15. The partition plate 11 is slidably connected to the sliding cavity 12 so that the partition plate 11 can drive the rotating ball head 9 to rotate, so that the suction cup 7 reaches the optimal adsorption angle. At the same time, the bonding plate 15 and the rotating rod 20 will be pressed together during the downward movement of the suction cup device 1, and the rotating rod 20 will be rotated under the action of the spiral groove 25, and the rotating rod 20 can drive the limit pin rod 22 to complete the limiting clamping of the spherical sleeve 8 and the rotating ball head 9, thereby achieving automatic locking while adjusting the angle of the rotating ball head 9 as the suction cup device 1 moves downward, thereby avoiding the angle change of the rotating ball head 9 or the detachment of the fixed object during subsequent lifting or movement.

[0035] like Figure 1 - Figure 8 As shown, an active cavity 27 is opened in the middle of the first connecting rod 16, and a piston plate 28 is slidably connected to the inside of the active cavity 27. The piston plate 28 is fixedly connected to the bottom of the rotating rod 20 through the second connecting rod 26. A plurality of overflow cavities 14 are arranged inside the bonding plate 15. The interior of the overflow cavity 14 is connected to the active cavity 27, and the interior of the active cavity 27 is filled with a filling medium.

[0036] Furthermore, the filling medium is made of liquid material, and the density of the filling medium liquid can be selected according to the surface roughness of the driving ring 19 .

[0037] When in use, as the first connecting rod 16 and the rotating rod 20 slide, the piston plate 28 will be driven to slide inside the active chamber 27, so that the filling medium inside the active chamber 27 overflows through the overflow chamber 14 to between the suction cup 7 and the fitting surface 29. The filling medium is set to be liquid, which increases the surface liquid tension between the suction cup 7 and the fitting surface 29, thereby improving its adsorption and fixing effect.

[0038] like Figure 1 - Fig.10 As shown, a closing hole 31 is opened in the middle of the partition plate 11, and the interior of the closing hole 31 is elastically connected to a closing plate 32 through an elastic member 33. A stop rod 30 is provided at the bottom of the fixing rod 17, and the position of the stop rod 30 corresponds to that of the closing plate 32.

[0039] Furthermore, the cross section of the closing plate 32 is trapezoidal, and the side of the closing plate 32 with a smaller area faces one end of the support rod 30 .

[0040] When in use, the partition plate 11 is closed by the closing plate 32. Since the sliding chamber 12 is connected to the connecting tube 5, the negative pressure in the initial bonding stage will cause external impurities of the suction cup 7 to enter between the suction cup 7 and the bonding surface 29, affecting the bonding effect. In order to avoid the negative pressure from pulling the external impurities in the initial bonding stage, the sliding chamber 12 needs to be closed. A partition plate 11 is provided, and a closing plate 32 is provided on the partition plate 11. The closing plate 32 closes the partition plate 11 under negative pressure. As the suction cup device 1 moves downward, the bonding plate 15 will drive the partition plate 11 to move inside the sliding chamber 12. When the push rod 30 contacts the closing plate 32, the closing plate 32 will open. At this time, the angle adjustment of the suction cup 7 has been completed and it is bonded to the surface of the bonding surface 29. At this time, the sliding chamber 12 is connected to the suction cup 7, thereby completing the adsorption and fixation of the bonding surface 29.

[0041] like Figure 1 - Fig.13 As shown, the inner wall of the suction cup 7 is provided with a suction hole 24 , and the suction hole 24 is connected with the sliding cavity 12 through the connecting hole 23 .

[0042] Furthermore, there may be multiple groups of adsorption holes 24 , and the multiple groups of adsorption holes 24 are evenly distributed along the inner wall edge of the suction cup 7 .

[0043] When in use, a plurality of adsorption holes 24 are provided on the inner wall of the suction cup 7 to improve the adsorption effect between the suction cup 7 and the bonding surface 29, and the adsorption holes 24 are connected to the sliding cavity 12 through the connecting holes 23. The negative pressure inside the sliding cavity 12 improves the bonding effect of the suction cup 7 with the bonding surface 29, thereby further improving the adsorption and fixing effect of the suction cup 7 on the bonding surface 29.

[0044] Working principle: The adsorption component 2 is made to fit with the bonding surface 29 by controlling the movement of the suction cup device 1. The adsorption component 2 is provided with multiple groups and distributed in an array, which can effectively improve the bonding effect with the bonding surface 29, and provide negative pressure to the inside of the negative pressure chamber 3 through the negative pressure tube 4. The adsorption component 2 is provided with an adaptive angle component 6 and a suction cup 7. The adaptive angle component 6 adaptively adjusts the angle between the suction cup 7 and the bonding surface 29 according to the surface curvature of the bonding surface 29, so as to maximize the bonding effect between the suction cup 7 and the bonding surface 29, thereby improving the adsorption and fixing effect of the suction cup 7. The adaptive angle component 6 can enable the device to effectively adsorb and fix special-shaped parts or objects with uneven surfaces. During the downward movement of the suction cup device 1, the bonding component 10 first fits with the bonding surface 29. If the surface of the fitting surface 29 is inclined, the fitting component 10 drives the rotating ball head 9 to tilt inside the spherical sleeve 8 through the partition plate 11, and finally makes the fitting component 10 tangent to the surface of the fitting surface 29. At this time, the suction cup 7 fits with the fitting surface 29 to achieve the best adsorption and fixing effect, so that the adaptive angle component 6 can adaptively adjust the angle according to the surface curvature of the fitting surface 29 to achieve the best adsorption and fixing effect. The driving disk 18 is suspended in the middle of the sliding cavity 12 through the fixing rod 17, and the driving ring 19 is driven to rotate by controlling the rotation of the rotating rod 20, and the driving protrusion 21 is arranged on the outer end surface of the driving ring 19, and the driving protrusion 21 is elastically fitted with the limit pin rod 22. The side where the driving protrusion 21 fits with the limit pin rod 22 is an arc surface or an inclined surface, so that The driving protrusion 21 can drive the limiting pin rod 22 to slide inside the fixing rod 17 during the rotation of the driving ring 19, so that the limiting pin rod 22 extends from the inside of the rotating ball head 9 and abuts against the inner wall of the spherical sleeve 8 to complete the fixation of the spherical sleeve 8 and the rotating ball head 9. The first connecting rod 16 is fixedly connected to the partition plate 11, and the bonding plate 15 is arranged parallel to the partition plate 11. The bonding plate 15 is bonded to the bonding surface 29 as the suction cup device 1 moves downward, and the bonding surface 29 is deflected as the curvature of the surface is deflected, thereby driving the partition plate 11 to deflect through the bonding plate 15. The partition plate 11 is slidably connected to the sliding cavity 12, so that the partition plate 11 can drive the rotating ball head 9 to rotate, so that the suction cup 7 reaches the optimal adsorption angle. At the same time, when the suction cup device 1 moves downward, The bonding plate 15 and the rotating rod 20 are pressed together, and the rotating rod 20 is rotated under the action of the spiral groove 25, and the rotating rod 20 can drive the limit pin rod 22 to complete the limit clamping of the spherical sleeve 8 and the rotating ball head 9, so that as the suction cup device 1 moves down, the rotating ball head 9 can be automatically locked while adjusting the angle, so as to avoid the angle of the rotating ball head 9 changing or the detachment of the fixed object during subsequent lifting or movement. As the first connecting rod 16 and the rotating rod 20 slide, the piston plate 28 is driven to slide inside the active chamber 27, so that the filling medium inside the active chamber 27 overflows through the overflow chamber 14 to between the suction cup 7 and the bonding surface 29. The filling medium is set to be liquid, which increases the surface liquid tension between the suction cup 7 and the bonding surface 29, thereby improving its adsorption and fixing effect.The partition plate 11 is closed by the closing plate 32. Since the sliding cavity 12 is connected to the connecting pipe 5, the negative pressure at the initial stage of bonding will cause the external impurities of the suction cup 7 to enter between the suction cup 7 and the bonding surface 29, affecting the bonding effect. In order to avoid the negative pressure from pulling the external impurities at the initial stage of bonding, the sliding cavity 12 needs to be closed. The partition plate 11 is provided, and the partition plate 11 is provided with a closing plate 32. The closing plate 32 closes the partition plate 11 under negative pressure. As the suction cup device 1 moves downward, the bonding plate 15 will drive the partition plate 11 to move inside the sliding cavity 12. When the push rod When the suction cup 7 contacts the closing plate 32, the closing plate 32 will be opened. At this time, the angle adjustment of the suction cup 7 is completed and the suction cup 7 is in contact with the bonding surface 29. At this time, the sliding cavity 12 is connected with the suction cup 7, thereby completing the adsorption and fixation of the bonding surface 29. The inner wall of the suction cup 7 is provided with multiple groups of adsorption holes 24 to improve the bonding and adsorption effect of the suction cup 7 and the bonding surface 29. The adsorption holes 24 are connected with the sliding cavity 12 through the connecting hole 23. The negative pressure inside the sliding cavity 12 improves the bonding effect of the suction cup 7 with the bonding surface 29, thereby further improving the adsorption and fixation effect of the suction cup 7 on the bonding surface 29.
