[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0031] like Figure 1-Figure 7 As shown, an embodiment of the present application provides a positioning tool for processing a liquid crystal display screen, comprising:

[0032] The four top corners of the fixed plate 1 are respectively arranged with two connecting columns 2 and two fixing columns 3 at intervals and staggered positions. The connecting columns 2 and the fixing columns 3 are vertically connected to the fixed plate 1, and the two connecting columns 2 are located at two diagonally opposite corners of the fixed plate 1, and the two fixing columns 3 are located at the other two diagonally opposite corners of the fixed plate 1;

[0033] The storage plate 4 and the fixed plate 1 are both square plates. They are parallel to the fixed plate 1 and connected to the tops of the connecting columns 2 and the fixed columns 3. The storage plate 4 is fixedly connected to the two connecting columns 2 and the two fixed columns 3 by a bolt assembly. Push plates 5 are slidably fitted around the storage plate 4. The sliding directions of adjacent push plates 5 are perpendicular to each other, and the middle of the storage plate 4 is located in the sliding direction of the multiple push plates 5. A first interference portion 6 is provided on the ends of the multiple push plates 5. The first interference portion 6 includes a connecting plate 601 that is in sliding contact with the top of the storage plate 4. A rubber block 602 is connected to the end of the connecting plate 601. When the multiple push plates 5 slide relative to each other, the rubber block 602 can interfere with the peripheral side of the LCD screen;

[0034] Two pushing components 7 are respectively provided on the two fixed columns 3. The pushing components 7 include two hinged plates 8 hinged to the fixed columns 3 in an upper and lower staggered shape. A driving part 9 is provided on each of the two hinged plates 8. The two driving parts 9 are respectively provided on adjacent sides of the storage plate 4, which are used to drive the push plate 5 to slide. When the two hinged plates 8 rotate away from each other with the diagonal line of the fixed plate 1 as the center line, the angle between the two hinged plates 8 gradually increases. At this time, the two driving parts 9 move away from each other. At this time, the push plate 5 can be pushed to slide in a direction away from the middle of the fixed plate 1 and contact with the driving part 9, and the LCD screen is placed on the top of the storage plate 4. Then, the two hinged plates 8 are driven to rotate relative to each other. At this time, the angle between the two hinged plates 8 gradually decreases, and the two driving parts 9 approach each other and push the push plate 5 to slide in the direction of the middle of the fixed plate 1;

[0035] Two elastic members 10 are respectively provided on the two fixed columns 3 and are used to drive the two hinge plates 8 to move closer to each other. The elastic members 10 include two torsion springs installed on the sides of the fixed columns 3. One end of each torsion spring is connected to the fixed column 3, and the other ends of the two torsion springs are respectively fixed to the two hinge plates 8. The two torsion springs can drive the two hinge plates 8 to rotate relative to each other.

[0036] When the two hinged plates 8 are in contact with each other, the two hinged plates 8 will be released.

[0037] The driving member 13 is provided on the slide groove 11 and is used to drive the two resisting members 12 to slide synchronously in opposite directions or relative to each other. Such a design enables the two resisting members 12 to be linked to each other, thereby driving the four hinged plates 8 to rotate synchronously.

[0038] The present application adopts the design of the interference member 12. When the two interference members 12 move away from each other through the driving member 13, the two hinged plates 8 on the same fixed column 3 can rotate away from each other under the interference of the interference member 12, and the angle between the two gradually increases. After the LCD screen is placed, the two interference members 12 can be driven to move relative to each other. At this time, the two hinged plates 8 on the same fixed column 3 can rotate relative to each other under the action of two torsion springs, and the driving part 9 pushes the push plate 5 to fit the peripheral side of LCD screens of different sizes and fix them. Compared with the existing technology, it has the advantages of simple structure and easy operation, is convenient for fixing LCD screens of different sizes, and is practical.

[0039] like Figure 1 、 Figure 3 and Figure 6 As shown, in some embodiments, the hinge plate 8 is an L-shaped plate, which has a first section 801 and a second section 802 connected perpendicularly to each other, the first section 801 is hinged to the fixing column 3, and the resistance member 12 resists the side where the two first sections 801 are close to each other. The second sections 802 of the two hinge plates 8 on the same side are respectively arranged on the side where the first sections 801 are away from each other, and the driving part 9 is arranged at the end of the second section 802. By adopting the design of the L-shaped plate, when the push plate 5 is released from fixing the LCD screen, the opening angle between the two first sections 801 is small, which facilitates the resistance member 12 to quickly drive the two hinge plates 8 to move.

[0040] like Figure 3 and Figure 6As shown, in some embodiments, the driving portion 9 includes a mounting column 901 vertically connected to the end of the second section 802, on which a stop block 902 is coaxially hinged, which is in contact with and overlaps the outer side of the push plate 5, and the outer side is the side of the push plate 5 away from the middle of the storage plate 4. With such a design, when the two first sections 801 drive the second section 802 to rotate relative to each other, the stop block 902 can push the push plate 5 to slide and slide on its outer side. During the sliding process, the stop block 902 can rotate along its own hinge point and fit tightly with the outer side of the push plate 5, thereby increasing the contact area between the two and facilitating the sliding of the push plate 5.

[0041] like Figure 3 and Figure 5 As shown, in some embodiments, a plurality of magnetic blocks 14 are installed on the block 902. The magnetic blocks 14 are strong magnets that are magnetically connected to the push plate 5. The push plate 5 is a stainless steel plate. The magnetic blocks 14 are installed on the side of the block 902 facing the push plate 5. With this design, when the two hinged plates 8 rotate in opposite directions, the push plate 5 can move with the block 902 under the adsorption of the magnetic blocks 14, so that the plurality of push plates 5 can slide in a direction away from the middle of the storage plate 4, thereby contacting and fixing the LCD screen.

[0042] like Figure 3 and Figure 5 As shown, in some embodiments, a mounting groove 15 is provided on one side of the block 902, and the magnetic block 14 is cylindrical and rotatably installed in the mounting groove 15. Multiple magnetic blocks 14 are linearly distributed along the length direction of the mounting groove 15, and the circumferences of multiple magnetic blocks 14 are tangent to the push plate 5 when sliding. Such a design can effectively reduce the wear between the magnetic block 14 and the push plate 5 when the block 902 slides, thereby extending the service life of the device.

[0043] like Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, in some embodiments, the resistance member 12 includes a slider 1201 that slides with the slide groove 11, and has two support rods 1202 coaxially hinged thereon, the axes of the two support rods 1202 are located on the diagonal of the fixed plate 1, and the two support rods 1202 are hinged on the side of the slider 1201 facing the fixed column 3, and the ends of the two support rods 1202 are connected with column blocks 1203, and the two column blocks 1203 are respectively magnetically connected to the two hinge plates 8, the column blocks 1203 are strong magnets, and the hinge plates 8 are all stainless steel plates. The two column blocks 1203 are movably overlapped with the sides of the two hinge plates 8 that are close to each other, and the two hinge plates 8 are both constructed with fixed blocks 1204 that movably interfere with the column blocks 1203, and the angle between the end of the fixed block 1204 and the hinge plate 8 is less than ninety degrees. On the side where the two hinge plates 8 are close to each other, the two cylindrical blocks 1203 are respectively adsorbed on the two hinge plates 8. When the slider 1201 slides toward the fixed column 3, the fixed column 3 can contact the angle between the fixed block 1204 and the hinge plate 8. At this time, the two support rods 1202 cannot move further. By continuing to move the slider 1201, the two support rods 1202 can rotate away from each other along their own hinge points, so that the angle between the two gradually increases, and thereby drive the two hinge plates 8 to rotate away from each other. When the slider 1201 slides in the direction away from the fixed column 3, under the action of the elastic member 10, the two hinge plates 8 approach each other and push the push plate 5 to contact the LCD screen. At this time, the two hinge plates 8 cannot rotate further, and the cylindrical blocks 1203 can slide on the hinge plates 8 as the slider 1201 slides.

[0044] like Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As shown, in some embodiments, an arc-shaped groove 1205 is provided on the side of the fixed block 1204 facing the slider 1201, which is used to accommodate the column block 1203. When the fixed column 3 can contact the end of the fixed block 1204, the two support rods 1202 drive the two hinged plates 8 to move oppositely under the action of the slider 1201. Under the action of the elastic force of the elastic member 10 and the thrust of the slider 1201, the fixed block 1204 and the column block 1203 conflict with each other and generate greater pressure. By adopting the design of the arc-shaped groove 1205, the contact area between the column block 1203 and the fixed block 1204 can be increased, thereby reducing the pressure on the column block 1203 when the two support rods 1202 and the two hinged plates 8 are opened, so that wear is less likely to occur between the column block 1203 and the fixed block 1204.

[0045] like Figure 3 、 Figure 6 and Figure 7As shown, in some embodiments, the driving member 13 includes a bidirectional screw rod 1301 provided in the slide groove 11, and the two ends of the bidirectional screw rod 1301 are respectively rotatably installed on the two fixed columns 3, and the two sliders 1201 are respectively threaded with the two ends of the bidirectional screw rod 1301. When the bidirectional screw rod 1301 rotates, the two sliders 1201 can be driven to move synchronously relative to or opposite to each other. A motor 1302 is installed on the slide groove 11. The motor 1302 is a hollow shaft stepping motor 1302, which is installed in the middle of the slide groove 11 and is used to drive the bidirectional screw rod 1301 to rotate.

[0046] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
