Description

Technical Field

[0001] This invention relates to the field of adsorption equipment, specifically to a deflection adsorption device. Background Technology

[0002] In today's industrial automation and precision manufacturing fields, increasingly higher demands are being placed on the technology for handling thin and light materials. Traditional adsorption devices, such as ordinary suction cups, often rely on direct contact with the material surface to generate adsorption force. However, this adsorption method has significant limitations when handling thin and light materials. The thinness of the material necessitates extremely precise control over the distribution of adsorption force and contact pressure. If there is a large contact angle between the suction cup and the material, it can lead to uneven distribution of adsorption force or excessive contact pressure, resulting in problems such as obvious adsorption marks and unstable adsorption connections.

[0003] To solve the above problems, accordion suction cups are currently used to replace conventional suction cups. The adaptive suction head of the accordion suction cup can achieve small-angle deflection adsorption. However, long-term use has proven that the deflection angle of the accordion suction cup is limited, and it can usually achieve stable adjustment of the adsorption process within a range of 5°. However, for thinner materials, they often need to be stacked and stored. The accumulation of materials often leads to a tilt angle of more than 25°. Therefore, conventional accordion suction cups are also difficult to solve this problem. Summary of the Invention

However, the embodiments described are not intended to limit the present invention.

[0027] Example

[0028] See Figure 1 As shown, this embodiment provides a deflection adsorption device, which includes: a flipping mechanism 100, the flipping mechanism 100 including a first driver 110 and a flipping frame 130, the flipping frame 130 being connected to the first driver 110 and deflecting around a rotation center line; at least one adsorption mechanism 200, the adsorption mechanism 200 being connected to the flipping frame 130 and rotating synchronously with the flipping frame 130; and two limiting mechanisms 300, the two limiting mechanisms 300 being respectively disposed on both sides of the adsorption mechanism 200 along the extension direction of the rotation center line, each of the limiting mechanisms 300 including at least one limiting member 350, and the limiting members 350 of the two limiting mechanisms 300 moving closer to / away from the flipping frame 130.

[0029] The deflection adsorption device of this invention uses a flipping mechanism 100 to drive the adsorption mechanism 200 to deflect at a large angle. This allows for flexible adjustment based on the actual placement angle of the material 500 during adsorption, maximizing the connection stability between the adsorption mechanism 200 and the material 500. Simultaneously, the limiting mechanism 300 provides lateral auxiliary limiting of the material 500, further preventing the risk of material 500 detaching during transport and limiting its position, thereby improving the accuracy of loading and unloading. Compared to conventional adsorption equipment, this application offers advantages such as wide applicability, flexible adjustment, and high adsorption stability, providing a new approach to multi-angle material 500 adsorption technology.

[0030] See Figure 1 and Figure 2 As shown, in the deflection adsorption device of this embodiment, the adsorption mechanism 200 is used to directly contact and adsorb the material 500, the flipping mechanism 100 is used to drive the adsorption mechanism 200 to adjust the actual working angle, and the limiting mechanism 300 is used to limit the material 500 from the side to improve the accuracy of material 500 transfer and adsorption. In order to connect the above structures, this embodiment also provides a connecting mechanism 400. The connecting mechanism 400 includes a top plate 430 and two side plates 440. The two side plates 440 are symmetrically arranged on opposite sides of the top plate 430 along the extension direction of the rotation center line. The flipping mechanism 100 is connected to the top plate 430 and located between the two side plates 440. The two limiting mechanisms 300 are respectively connected to the two side plates 440. The top plate 430 and the two side plates 440 together enclose an accommodating space. The flipping mechanism 100 is connected in the accommodating space to achieve the miniaturization of the overall structure of this application.

[0031] Furthermore, the connecting mechanism 400 also includes a clamping block 410 and a circuit interface 420. The clamping block 410 is disposed on the top plate 430 to connect to an external mobile device, and the circuit interface 420 is connected to one side of the top plate 430 to connect to the control system. Preferably, the clamping block 410 consists of two arc-shaped clamps that can open and close relative to each other, used to clamp and connect an external handling robot. The circuit interface 420 is used to realize the automated control of this device. In different embodiments, the external handling device can also be a crane, a robotic arm, a mobile module, or other equipment capable of spatial transfer; this invention does not impose specific limitations on this.

[0032] See Figure 3As shown, in the flipping mechanism 100, the flipping frame 130 provides an installation and connection platform for the adsorption mechanism 200, and the first driver 110 provides a flipping driving force for the flipping frame 130. It is preferably a linear drive motor. Furthermore, in order to ensure the driving effect of the linear drive motor on the flipping frame 130, a transmission assembly 120 is also provided in this example. The transmission assembly 120 is disposed between the first driver 110 and the flipping frame 130. It includes a lifting block 121, a connecting rod 122, and a connecting member 123. The lifting block 121 is connected to the working end of the first driver 110 to move along the height direction of the flipping mechanism 100. The connecting member 123 is connected to the flipping frame 130. The two ends of the connecting rod 122 are rotatably connected to the lifting block 121 and the connecting member 123, respectively. Based on the above structure, this embodiment can position the motor directly above the tilting frame 130, and achieve unilateral deflection drive of the tilting frame 130 through the transmission component 120, thereby realizing the miniaturized structure of this application through reasonable layout. In different embodiments, different numbers of transmission components 120 can be set in different positions according to actual use, thereby further improving the transmission effect of the motor.

[0033] Furthermore, in this embodiment, the flipping frame 130 includes a base plate 132 and at least one assembly part 131. The assembly part 131 is connected to the base plate 132. One end of the adsorption mechanism 200 is connected to the assembly part 131, and the other end passes through the base plate 132 to contact the material 500. Based on this structural arrangement, the adsorption mechanism 200 can be simultaneously limited and fixed by the assembly part 131 and the base plate 132, thereby improving its stability and connection strength during the adsorption process.

[0034] See Figure 4As shown, in this embodiment, to improve the flipping accuracy of the flipping frame 130, the flipping mechanism 100 further includes a positioning component 140. The positioning component 140 includes a sensing plate 141 and a positioning sensor 142. The positioning sensor 142 is connected to the side wall of the first driver 110, and the sensing plate 141 is connected to the working end of the first driver 110. The sensing plate 141 moves up and down with the first driver 110 to pass through / away from the positioning sensor 142. Further, the positioning component 140 also includes a lifting adjuster 143 and a mounting base 144. The mounting base 144 is connected to the side wall of the first driver 110, and the positioning sensor 142 is adjustablely connected to the mounting base 144. The working end of the lifting adjuster 143 is connected to the positioning sensor 142 to drive the positioning sensor 142 to move. Before operation, the operator can adjust the installation position of the position sensor 142 according to the actual required flip angle. The sensing plate 141 is set at the working end of the first driver 110 and can move synchronously with the transmission component 120 through the first driver 110. Therefore, when the other end of the sensing plate 141 is inserted into the position sensor 142, the position sensor 142 can provide specific position feedback so as to achieve accurate feedback on whether the first driver 110 is in position during operation.

[0035] See Figure 5 As shown, this embodiment includes four adsorption mechanisms 200, which are respectively connected to the four corners of the base plate 132, thereby achieving a uniform force distribution on the base plate 132. The four adsorption mechanisms 200 in this embodiment have identical structures; one of them will be used as an example for structural description: See [link to documentation]. Figure 5As shown, the adsorption mechanism 200 in this embodiment includes a tube 220, a fixing member 210, an accordion suction cup 230, and a positioning ring 240. The tube 220 is connected to an external negative pressure device. The accordion suction cup 230 and the fixing member 210 are respectively disposed at both ends of the tube 220. The tube 220 is connected to the flipping plate through the fixing member 210. The accordion suction cup 230 is positioned facing the material 500, and the positioning ring 240 is positioned around the accordion suction cup 230. The tube body 220 serves two purposes: connecting the fixing member 210 and the bellows suction cup 230, and also connecting to the negative pressure device. The fixing member 210 secures the tube body 220 to the assembly part 131, preferably using connecting bolts. The bellows suction cup 230 is positioned below the base plate 132 to facilitate contact with the material 500. The positioning ring 240 provides a precise positioning reference for the bellows suction cup 230 during precision assembly or processing, ensuring accurate positioning of the workpiece during processing or assembly. Furthermore, the positioning ring 240 simplifies the operation process, reduces adjustment and calibration time, and thus improves production efficiency. In different embodiments, other numbers of adsorption mechanisms 200 can be provided according to actual production and processing needs. Multiple adsorption mechanisms 200 can also be connected at different positions on the flipping frame 130 according to the shape and size of the material 500; this invention does not impose specific limitations in this regard.

[0036] See Figure 6As shown, this embodiment includes two limiting mechanisms 300, which are symmetrically arranged to limit the material 500 in the horizontal direction. Specifically, the limiting mechanism 300 in this embodiment also includes a sliding plate 310 and a first connecting shaft 330. The sliding plate 310 moves up and down along the height direction of the flipping mechanism 100. The limiting member 350 passes through the middle of the first connecting shaft 330, and its two ends are respectively embedded in the sliding plate 310. The limiting member 350 is connected to the sliding plate 310 through the first connecting shaft 330 and moves synchronously with the sliding plate 310. The sliding plate 310 can drive the limiting member 350 to move up and down, and the first connecting shaft 330 is used to connect the limiting member 350 and the sliding plate 310. Furthermore, the limiting mechanism 300 also includes a slide 360, a second driver 320, and a second connecting shaft 340. The second driver 320 is connected to the slide plate 310, the slide 360 ​​is connected to the working end of the second driver 320, and moves up and down relative to the slide plate 310. The second connecting shaft 340 is disposed on the slide 360. The limiting member 350 is provided with an arc-shaped guide groove 351, and the second connecting shaft 340 passes through the arc-shaped guide groove 351 to slidably connect to the limiting member 350. Specifically, the second driver 320 is preferably a linear motor. In this embodiment, the second connecting shaft 340 can move along the arc-shaped guide groove 351 to achieve the purpose of driving the two limiting members 350 to move closer / away from each other.

[0037] In summary, the deflection adsorption device of this invention, through the flipping mechanism 100 driving the adsorption mechanism 200 to deflect at a large angle, allows for flexible adjustment based on the actual placement angle of the material 500 during the adsorption process. This maximizes the connection stability between the adsorption mechanism 200 and the material 500. Simultaneously, the limiting mechanism 300 provides lateral auxiliary limiting of the material 500, further preventing the risk of material 500 detaching during transport and limiting its position, thereby improving the accuracy of loading and unloading. Compared to conventional adsorption equipment, this application offers advantages such as wide applicability, flexible adjustment, and high adsorption stability, providing a new approach to multi-angle material 500 adsorption technology.
