Description

Technical Field

[0001] The utility model belongs to a tool for positioning, specifically a positioning device for assembling liquid crystal screens into a whole and an intelligent positioning of liquid crystal screens. Background Technique

[0002] When the existing liquid crystal screens are assembled into a whole, the liquid crystal screens are neatly installed on an array frame one by one, and then fixed with fixing parts and connected with cables to achieve an overall effect. However, the disadvantage of this solution is that the liquid crystal screens must be neatly installed on a pre-made metal array frame without deviation.

[0003] In many existing application scenarios, when many liquid crystal screens are assembled, they need to be assembled into a whole with deviations from each other. For example, "a transparent floor tile screen with complete transparency and force perception" (authorization announcement number: CN111161647B). When laying this kind of floor tile screen on the ground, fillers such as cement need to be laid between the floor tile screens. In addition, due to installation requirements or ground conditions, there may be deviations in the horizontal and vertical directions between them.

[0004] Therefore, people need to face the deviation problem between liquid crystal screens and provide a relatively accurate fixing effect to position the liquid crystal screens relative to each other. Summary of the Invention

[0005] Based on the existing electronic technology, the utility model proposes a tool for intelligent positioning of liquid crystal screens in a scenario where there are horizontal and vertical deviations between liquid crystal screens and a certain distance in the middle. By implementing it, first, in the face of the deviation problem between liquid crystal screens, the liquid crystal screens can be positioned relative to each other with a relatively accurate fixing effect; second, the tool itself is convenient and efficient to use, which is beneficial for ordinary workers to install and use quickly, reduces the workload of workers, and reduces the professionalism of operation.

[0030] Embodiment 1

[0031] As Figure 2 shown, a positioning device for the combined installation of LCD screens according to the present utility model mainly includes two magnetic attraction detection devices and a control circuit board;

[0032] The two magnetic attraction detection devices include a magnetic attraction detection device A and two magnetic attraction detection devices B;

[0033] The control circuit board includes a second microprocessor;

[0034] The magnetic attraction detection device includes a connecting member, and a plurality of laser pair-switches and magnets arranged on the connecting member. The laser pair-switches are connected to the second microprocessor. The laser pair-switch includes a laser emitting tube 11 and a laser receiving tube. The laser emitting tube and the laser receiving tube are both connected to the second microprocessor through locking terminals. The laser emitting tube 11 is located in the magnetic attraction detection device A, and the laser receiving tube 21 is located in the magnetic attraction detection device B.

[0035] The connecting member is a long strip structural member with an L-shaped cross-section, including a long side and a short side; the long side is fixed to the back of the liquid crystal screen, as Figure 1 , 3 shown, the laser pair-switch and the magnet are arranged on the short side at equal intervals along the length direction of the connecting member; specifically, a hole is drilled every 40 mm on the short side, and a laser pair-switch is installed in each hole. A magnet is installed between two adjacent laser pair-switches, and the diameter of the magnet is 5 mm; in the present invention, the laser pair-switch used is an M8-sized laser pair-switch of model E3F, and its detection distance is 15 mm.

[0036] The connecting member in this specific embodiment is a non-magnetic plastic steel with an L-shaped cross-section.

[0037] When the liquid crystal screen is produced, the positioning device and the liquid crystal screen are produced together; or the positioning device of the present invention is separately installed on the back of two liquid crystal screens that need to be installed side by side. Two magnetic attraction detection devices are respectively arranged on the backs of the two liquid crystal screens, and two types of magnetic attraction detection devices A and B are arranged along the adjacent sides of the two liquid crystal screens, which are used to detect whether there is a liquid crystal screen at the adjacent position of the liquid crystal screen and the relative position deviation of the liquid crystal screen.

[0038] A plurality of holes with fixed intervals are formed on the connecting member, and the laser pair-switch and the magnet are installed, and they are assembled in an alternating manner. There are two types. The magnetic attraction detection device A includes a laser emitting tube 11, and a first magnet 12 is sandwiched in the middle, with the N pole facing the adjacent liquid crystal screen, that is, facing the magnetic attraction detection device B; the magnetic attraction detection device B includes a laser receiving tube 21, and a second magnet 22 is sandwiched in the middle, with the S pole facing the adjacent liquid crystal screen, that is, facing the magnetic attraction detection device A. Since the hole pitch between them is fixed, in the face-to-face situation, the two types of magnetic attraction detection devices A and B are exactly completely attracted to each other. If there is a longitudinal deviation, it will be attracted by the positive and negative poles of the magnet towards a fixed distance of 20 mm. In this way, the deviation distance between the two magnetic attraction detection devices A and B can be made into a fixed distance in actual operation, and this distance can be simply looked up through the 0 and 1 coding of the laser pair-switch.

One side of the first liquid crystal display screen is adjacent to the second liquid crystal display screen; the magnetic induction detection device B is arranged on the back of the second liquid crystal display screen and along one side of the second liquid crystal display screen. One side of the second liquid crystal display screen is adjacent to the first liquid crystal display screen; the control circuit board connected to the magnetic induction detection device A and the magnetic induction detection device B can be installed on the back of any one of the liquid crystal display screens.

[0041] When the first liquid crystal display screen and the second liquid crystal display screen are close to each other, the second microprocessor detects the switch changes of all its own laser pair emission switches, such as Figure 3 As shown, the ones receiving the laser are set to 1, and the ones not receiving the laser are set to 0, obtaining the position 0 and 1 codes, so as to know their relative positions. Then, using the mechanical structure parameters with a spacing of 20 mm each, look up the relative positions in the vertical or horizontal direction.

[0042] The control circuit board also includes an aviation plug. Through the aviation plug, the only second microprocessor also communicates with a first microprocessor each carried on the two liquid crystal display screens by itself, and the first microprocessor knows whether they are aligned;

[0043] Any two adjacent liquid crystal display screens can be defined as the first liquid crystal display screen and the second liquid crystal display screen, and they are installed according to the above method until all the liquid crystal display screens are installed.
