Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, which should not be construed as limiting the invention.

Example 1

As shown in fig. 1-3, the present invention provides a device for assembling a display screen of a liquid crystal television, including a rectangular substrate 1, four corners of the upper side of the substrate 1 are all fixedly connected with suspenders 11, the substrate 1 is horizontally fixed by the four suspenders 11, two horizontally arranged guide rails 2 are fixed at the lower side of the substrate 1, the two guide rails 2 are arranged in parallel, two sliders 3 are slidably connected to each guide rail 2, and two moving mechanisms for controlling the two sliders 3 to approach or separate from each other along the direction of the guide rails 2 are arranged at the lower side of the substrate 1; moving mechanism includes two parallel arrangement's riser 6, the equal fixed connection of two risers 6 is in 1 downside of base plate, be equipped with two sets of rotation holes between two risers 6, every group rotation hole is two, set up respectively in two riser 6's relative one side, all rotate between every group rotation hole and connect two-way threaded rod 61, two motors 62 of riser 6 one side fixed connection, motor 62 sets up with two-way threaded rod 61 one-to-one, every motor 62 main shaft all with the two-way threaded rod 61 one end fixed connection that corresponds, two sliders 3 on every guide rail 2 all are equipped with first screw hole, every two-way threaded rod 61 all passes first screw hole in proper order and is connected with 3 screw-thread fit of two sliders, the first screw hole of every two sliders 3 all revolves to opposite directions, every two sliders 3 all correspond threaded connection on the positive and negative screw thread section of two-way threaded rod 61. The starting motor 62 drives the bidirectional threaded rod 61 to rotate forward or backward, so that the two sliding blocks 3 on the guide rail 2 can horizontally move along the direction of the guide rail 2, and the two sliding blocks 3 on the guide rail 2 can approach or move away from each other. A guide pipe 31 which is vertically arranged is fixed on the lower side of each sliding block 3, a guide rod 4 is connected in each guide pipe 31 in a sliding manner, and a lifting mechanism for controlling the guide rod 4 to vertically move in the guide pipe 31 is arranged on the upper side of the base plate 1; the lifting mechanism comprises a cylinder 7, the cylinder 7 is fixedly connected to the upper side of the base plate 1, a connecting rod 71 is fixedly connected between every two oppositely arranged clamping blocks 5, a connecting plate 72 is fixedly connected between the two connecting rods 71, and a piston rod of the cylinder 7 penetrates through the base plate 1 and is fixedly connected to the upper side of the connecting plate 72. The connecting plate 72 can be driven to vertically ascend or descend by starting the air cylinder 7, so that the connecting plate 72 drives the guide rod 4 to vertically move in the guide pipe 31 through the connecting rods 71 on the two sides.

The lower end of each guide rod 4 is provided with a connecting groove, each connecting groove is internally connected with a clamping block 5 in a rotating way through a rotating shaft 41, and the anti-skid plate 52 is fixedly connected on one side, opposite to the two clamping blocks 5, of the lower side of each guide rail 2. The display screen 9 to be assembled is horizontally placed between the four clamping blocks 5, and the two sliding blocks 3 on the lower side of each guide rail 2 are close to each other through the moving mechanism, so that the display screen 9 can be horizontally fixed between the anti-skid plates 52 on the opposite sides of the four clamping blocks 5. The lifting mechanism drives the connecting plate 72 to vertically ascend or descend, so that the display screen 9 fixed among the four clamping blocks 5 can vertically move, and the display screen 9 can be moved to the upper side of the assembling position. Two ends of each guide rail 2 are provided with three vertically arranged jacks 8 at intervals, the base plate 1 is provided with six vertically arranged second threaded holes 81, and the second threaded holes 81 and the jacks 8 are in one-to-one correspondence and are coaxially arranged; every second screw hole 81 is interior equal screw-thread fit connection limit bolt 82, and every limit bolt 82 changes over into second screw hole 81 back homoenergetic and stretches out the guide rail 2 downside from jack 8 that corresponds. After the limit bolt 82 is rotated into the second threaded hole 81, the limit bolt extends out of the lower side of the guide rail 2 from the corresponding jack 8, when the motor 62 drives the two sliding blocks 3 on the guide rail 2 to approach each other, and when the two sliding blocks 3 move to the limit bolt 82 extending out of the lower side of the guide rail 2, the two sliding blocks 3 cannot approach each other, so that the distance between the two clamping blocks 5 can be limited; through stretching out spacing bolt 82 from the jack 8 of guide rail 2 different positions to change the interval that can press from both sides tightly between two clamp splice 5, thereby can press from both sides tight fixedly to not display screen 9 of equidimension, and then can press from both sides tight fixedly to not display screen 9 of equidimension, improve the suitability.

The upper side of each clamping block 5 is provided with a cambered surface 51, the groove bottom of each connecting groove is fixedly connected with a friction plate 42, and the friction plates 42 are in one-to-one correspondence with the cambered surfaces 51 and are abutted against the cambered surfaces. After the display screen 9 is horizontally fixed among the four clamping blocks 5 through the moving mechanism, the horizontally fixed display screen 9 is vertically moved to the upper side of the position convenient for assembly through the lifting mechanism. Starting a motor 62 to enable the two sliding blocks 3 on one guide rail 2 to be away from each other, so that the two clamping blocks 5 on the lower side of the guide rail 2 are separated from the two sides of the display screen 9; meanwhile, as the two clamping blocks 5 on the lower side of the other guide rail 2 clamp and fix the display screen 9, one side of the display screen 9 separated from the two clamping blocks 5 can be provided with the two clamping blocks 5 which clamp and fix the display screen 9 to rotate downwards by taking the rotating shaft 41 as a reference, so that one side of the display screen 9 separated from the two clamping blocks 5 can downwards extend into the assembly position, and a worker can assemble the display screen 9 extending into the assembly position. After the assembly of the display screen 9 stretching into the assembly position is completed, the display screen 9 still clamped and fixed by the two clamping blocks 5 moves downwards to a position close to the assembly position through the lifting mechanism again, then the two sliding blocks 3 on the guide rail 2 are separated from each other through the other motor 62, so that the two clamping blocks 5 on the lower side of the guide rail 2 are separated from the two sides of the display screen 9, the other side of the display screen 9 also can stretch downwards to the assembly position, and the worker can assemble the unassembled display screen 9 again. Through dividing into two units with display screen 9 and carrying out the assembly process respectively for when assembling display screen 9 one side, one side that display screen 9 did not assemble can not receive the disturbance because of the opposite side is assembling, avoids appearing not assembling display screen 9 and each connecting piece between the position because of receiving the disturbance and take place the skew, influence the normal use after the assembly. When the two clamping blocks 5 rotate downwards in the connecting grooves by taking the rotating shaft 41 as a reference, the cambered surfaces 51 on the upper sides of the clamping blocks 5 are continuously contacted with the friction plates 42, so that the clamping blocks 5 can slowly rotate in the connecting grooves, and the phenomenon that the display screen 9 is damaged due to large impact force when the display screen 9 extends into the assembling position because the clamping blocks 5 rotate too fast is avoided.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
