Description

Technical Field

[0001] The invention relates to the field of technical adsorption devices, and in particular to a curved surface adsorption mechanism. Background Art

[0002] Compared with traditional flat-panel displays, curved displays are more in line with the physiological curvature of the human eye, which can greatly enhance the user's sense of being wrapped and immersed when watching. Curved displays can bring better visual experience than flat-panel displays. When installing, curved displays need to use professional curved adsorption mechanisms to move them to curved light boxes. Previously, there was no real curved adsorption mechanism on the market. Two flat suction cup fixtures were often used to suck the liquid crystal panel and then fold it into a curved surface artificially. This posed a risk of breaking the liquid crystal panel, and a liquid crystal panel accounted for most of the cost of a liquid crystal display. At present, some suction cup fixtures with curved distribution have also emerged on the market, but their structure is fixed, their flexibility is poor, and their use is limited. Therefore, the present invention has developed a curved adsorption mechanism to solve the problems existing in the prior art. After searching, no technical solutions identical or similar to the present invention were found. Summary of the invention

[0003] The purpose of the present invention is to provide a curved surface adsorption mechanism to solve the problem that the suction cup fixture with a curved surface fixed distribution in the prior art has great limitations in use and poor flexibility.

[0025] like Figure 1 As shown, a curved surface adsorption mechanism includes a pair of swing arms 1 that can realize symmetrical rotation, a plurality of suction cups 2 installed under the swing arms 1, and a driving member 3 connected to the swing arms 1; the driving member 3 has a fixed end and a movable end that can realize telescopic movement, the fixed end and the movable end are respectively hinged to the pair of swing arms 1, and the swing arms 1 can be rotated through the action of the driving member 3, thereby enabling the suction cups 2 to complete the action of being adsorbed on a flat surface to bend on a curved surface.

[0026] Specifically, Figure 1 , Figure 2 As shown, a pair of swing arms 1 are connected by a pair of adapter plates 15, which are arranged in the horizontal direction and have their two ends hinged to the ends of the swing arms 1 respectively; the swing arm 1 includes a pair of parallel connecting plates 11, and a plurality of pairs of fixed plates 12 vertically arranged between the pair of connecting plates 11, and a pair of guide posts 13 and a slider 14 slidably matched with the guide posts 13 are installed between each pair of fixed plates 12; the central axis of the guide post 13 is perpendicular to the rotation axis of the swing arm 1 and is arranged parallel to the connecting plate 11; the slider 14 cooperates with the guide post 13 to reciprocate between the pair of fixed plates 12.

[0027] like Figure 1 , Figure 2 As shown, the suction cup 2 is fixedly installed under the slider 14 and the adapter plate 15 through the mounting strip 22. The mounting strip 22 is arranged in a direction perpendicular to the central axis of the guide column 13 and is respectively fixed to the lower ends of the slider 14 and the adapter plate 15. The two side edges extend outward, and waist-shaped grooves 23 are arranged on the end surfaces of both sides; a positioning column 21 is fixed to the upper end of the suction cup 2, and the positioning column 21 is inserted into the waist-shaped groove 23 and fixed by threaded bolts / nuts; in this embodiment, two suction cups 2 are installed in each waist-shaped groove 23, and four suction cups 2 are installed on each corresponding mounting strip 22, and four suction cups 2 are set as a group, and two groups of suction cups 2 are respectively installed on the lower ends of the adapter plate 15 and a pair of swing arms 1; in actual use, the number of suction cups 2 on the mounting strip 22 and a single mounting strip 22 is not limited.

[0028] The driving member 3 includes a base 31, an electric cylinder 32 installed on the base 31, and a slide 33 connected to the electric cylinder 32. The base 31 is the fixed end of the driving member 3 and is hinged to the two side edges of the swing arm 1 through a pair of connecting rods 34; the slide 33 is the movable end of the driving member 3, moves in a direction perpendicular to the rotation axis of the swing arm 1, and is hinged to the two side edges of the swing arm 1 on the other side through a pair of connecting rods 34; the electric cylinder 32 is a combination of a servo motor 321 and a lead screw 322, and both are installed on the base 31.

[0030] Step 1: If Figure 4 As shown, in the initial state, a pair of swing arms 1 are horizontal, and the lower end surfaces of the plurality of suction cups 2 are in the same horizontal plane, and the display 4 is adsorbed at this time; in this state, the plurality of positioning columns 21 are arranged in parallel along the vertical direction;

[0031] Step 2: The electric cylinder 32 moves to drive the slide 33 to retract. Figure 5 As shown, at this time, the distance between the two pairs of connecting rods 34 is reduced, the adapter plate 15 sinks, the pair of swing arms 1 bends upward and tilts up, and the displays 4 adsorbed by the lower end surfaces of the plurality of suction cups 2 are bent to form a curved surface; in this state, the positioning columns 21 on both sides are inclined (arranged along the radial direction of the formed curved surface), and since the suction cups 2 are fixed-point adsorption, the upper ends of the positioning columns 21 will approach the middle side of the overall mechanism, that is, Figure 3 As shown, the slide block 14 moves along the guide post 13 .
