[0001] The utility model relates to the technical field of LCD display screen detection, in particular to an LCD display screen detection device. Background Art

[0002] LCD is the abbreviation of Liquid Crystal Display. It uses a liquid crystal solution in two polarized materials. When an electric current passes through the liquid, the crystals will rearrange to form an image. It is a type of display used in digital watches and many portable computers and mobile phones.

[0003] According to a Chinese public patent with patent number CN209343077U, it is pointed out that a test needle is included, a detector is provided on the right side of the test needle, and two racks are horizontally provided on the front and back sides of the test table; the utility model can suck up the display screen through a suction cup, and the first lifting cylinder places the faulty product on the upper end of the waste table and the normal product on the upper end of the collection table, so that the detection process is automated and the production efficiency is improved.

[0004] When the above cited patent is actually used, the suction cup is used to modernize the detection process and improve production efficiency. However, the patent still has certain limitations when used. In the patent, the LCD display screen placed on the storage table by the staff is moved to the detection board through the suction cup. Since the LCD display screen on the storage table is placed manually, the position of each LCD display screen on the storage table cannot be consistent, resulting in incomplete bonding of the suction cup when the LCD display screen is attached, and the possibility of gaps. When the suction cup drives the LCD display screen to move, the LCD display screen may fall off, thereby causing damage to the LCD display screen. Therefore, in order to solve the above problems, an LCD display screen detection device is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an LCD display screen detection device, which has the advantages of being able to automatically load the LCD display screen at the same position, and solves the problem of incomplete adhesion of the suction cup to the LCD display screen due to different positions when loading the LCD display screen.

[0006] To achieve the above object, the utility model provides the following technical solution: an LCD display screen detection device includes a storage table: a limit groove is provided on the upper surface of the storage table and extends longitudinally through the storage table, two opposite receiving plates are sleeved in the limit groove, and the lower surfaces of the two receiving plates are connected to the bottom table;

[0007] The upper surface of the base platform is provided with a first lifting cylinder;

[0008] The output end of the first lifting cylinder is provided with a loading plate.

[0009] Furthermore, a limit plate is connected between the two receiving plates and fits with one side of the carrier plate. Two slide plates are connected to one side of the limit plate and are located on both sides of the carrier plate. The inner walls of the two slide plates are equipped with first slide rails and are arranged parallel to the carrier plate.

[0010] Furthermore, a second slide rail is installed at the other end of the first slide rail and is arranged at an obtuse angle with the first slide rail in the same horizontal plane.

[0011] Furthermore, three groups of storage blocks are provided on the inner walls of the two receiving plates facing each other, a groove is provided on one side of the storage block and two springs are connected to the inner wall of the groove, the other ends of the two springs are connected to a telescopic plate, the side of the telescopic plate connected to the spring is fitted in the groove of the storage block, and the lower surface of the telescopic plate is arranged in an inclined surface.

[0012] Furthermore, racks are installed on both sides of the upper surface of the storage table, and sliding grooves are opened on the opposite sides of the two racks, and the two opposite inner walls in the sliding grooves are respectively connected to the reciprocating motor and the bearing seat.

[0013] Furthermore, a forward and reverse screw is rotatably connected between the reciprocating motor and the bearing seat, two limit rods are connected between the reciprocating motor and the bearing seat and are located on both sides of the forward and reverse screw, and sliders are meshed and slidably engaged with the two limit rods and the forward and reverse screw.

[0014] Furthermore, a second lifting cylinder is connected to the upper surface of the two sliders, a suction cup is connected to the output end of the second lifting cylinder, a third lifting cylinder is provided on the upper surface of the two frames, a detector is connected to the output end of the third lifting cylinder, and an indicator light and a speaker are installed on the outer wall of the detector.

[0015] Furthermore, a detection plate is installed on the upper surface of the storage table, and the detection plate corresponds to the detector. A storage box and a waste box are embedded on the other side of the upper surface of the storage table.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] The LCD display screen detection device is characterized in that when the LCD display screen to be detected slides onto the first slide rail, the output end of the first lifting cylinder drives the loading plate to extend upward. When the LCD display screen is located between the two opposite telescopic plates, the upward thrust brought by the first lifting cylinder to the LCD display screen presses the telescopic plate to go deeper into the material storage block, thereby driving the compression of the spring. When the height of the LCD display screen rises to a level higher than the upper surface of the first group of material storage blocks, the output end of the first lifting cylinder retracts back. At this time, the spring restores its own shape to give the telescopic plate an outward elastic force to make the telescopic plate extend outward, thereby the LCD display screen can fall back to the upper surface of the first group of telescopic plates under the action of gravity. Similarly, when the first lifting cylinder pushes the next LCD display screen to be detected to the upper surface of the first group of telescopic plates, it can drive the first LCD display screen to be pushed to the upper surfaces of the second and third groups of telescopic plates. Thus, the LCD display screen to be detected can be automatically pushed to the upper surface of the telescopic plates, thereby avoiding the position deviation of each LCD display screen due to manual placement, thereby causing damage to the LCD display screen during subsequent detection.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 In this embodiment, an LCD display screen detection device includes a placement table 1: a limiting groove 18 is provided on the upper surface of the placement table 1 and extends longitudinally through the placement table 1, two opposite receiving plates 23 are sleeved in the limiting groove 18, and the lower surfaces of the two receiving plates 23 are connected to the base 2; a first lifting cylinder 21 is installed on the upper surface of the base 2; a loading plate 22 is installed at the output end of the first lifting cylinder 21.

[0025] A limit plate 25 is connected between the two receiving plates 23 and is in contact with one side of the carrier plate 22. Two slide plates 26 are connected to one side of the limit plate 25 and are located on both sides of the carrier plate 22. The inner walls of the two slide plates 26 are provided with a first slide rail 27 and are arranged parallel to the carrier plate 22. A second slide rail 28 is installed at the other end of the first slide rail 27 and is arranged at an obtuse angle to the first slide rail 27 in the same horizontal plane.

[0026] The inner walls of the two receiving plates 23 are oppositely provided with three groups of material storage blocks 24, one side of the material storage block 24 is provided with a groove and the inner wall of the groove is connected with two springs 241, and the other ends of the two springs 241 are connected with a telescopic plate 242, and the side of the telescopic plate 242 connected with the spring 241 is fitted in the groove of the material storage block 24, and the lower surface of the telescopic plate 242 is inclined. The length of the LCD display screen to be detected is less than the distance between the two oppositely arranged material storage blocks 24, and is greater than the distance between the two oppositely arranged material storage blocks 24; the length of the carrier plate 22 between the two slide plates 26 is less than the distance between the two oppositely arranged material storage blocks 24.

[0027] When the staff places the LCD display screen to be inspected on the two second slide rails 28, the LCD display screen slides downward to the first slide rail 27 due to the action of gravity. Under the action of the limit plate 25, the LCD display screen is stationary on the first slide rail 27 and is located above the carrier plate 22. At this time, the output end of the first lifting cylinder 21 drives the carrier plate 22 to stretch upward. When the LCD display screen is located between the two opposite telescopic plates 242, the upward thrust brought to the LCD display screen by the first lifting cylinder 21 presses the telescopic plates 242 to go deeper into the storage block 24, thereby driving the compression of the spring 241. When the height of the LCD display screen rises higher than the upper surface of the first group of storage blocks 24, the output end of the first lifting cylinder 21 drives the carrier plate 22 to stretch upward. The outlet end retracts back, at this time, the spring 241 returns to its own shape and gives an outward elastic force to the telescopic plate 242 to make the telescopic plate 242 stretch outward, and then the LCD screen can fall back to the upper surface of the first group of telescopic plates 242 under the action of gravity. Similarly, when the first lifting cylinder 21 pushes the next LCD screen to be inspected to the upper surface of the first group of telescopic plates 242, it can drive the first LCD screen to be pushed to the upper surface of the second and third groups of telescopic plates 242. In this way, the LCD screen to be inspected can be automatically pushed to the upper surface of the telescopic plates 242, avoiding the deviation of the position of each LCD screen due to manual placement, which in turn causes damage to the LCD screen during subsequent inspections.

[0028] Racks 11 are installed on both sides of the upper surface of the storage table 1, and slide grooves 12 are opened on the opposite sides of the two racks 11. The two opposite inner walls in the slide groove 12 are respectively connected to the reciprocating motor 13 and the bearing seat 14; a forward and reverse screw 15 is rotatably connected between the reciprocating motor 13 and the bearing seat 14, and two limit rods 16 are connected between the reciprocating motor 13 and the bearing seat 14 and are located on both sides of the forward and reverse screw 15, and sliders 17 are meshed and slidably engaged on the two limit rods 16 and the forward and reverse screw 15; a second lifting cylinder 3 is connected to the upper surface of the two sliders 17, and a suction cup 31 is connected to the output end of the second lifting cylinder 3, and a third lifting cylinder 32 is provided on the upper surfaces of the two racks 11, and a detector 33 is connected to the output end of the third lifting cylinder 32, and an indicator light 34 and a speaker 35 are installed on the outer wall of the detector 33.

[0029] A detection plate 4 is installed on the upper surface of the storage table 1 , and the detection plate 4 corresponds to the detector 33 . A storage box 5 and a waste box 6 are embedded on the other side of the upper surface of the storage table 1 .

[0030] When the LCD display screen is pushed to the upper surface of the third group of telescopic plates 242, the second lifting cylinder 3 drives the suction cup 31 to fit the surface of the LCD display screen, and under the action of the reciprocating motor 13, the forward and reverse screws 15 are driven to rotate. With the cooperation of the limit rod 16, the slider 17 makes a reciprocating motion within the stroke range of the forward and reverse screws 15, thereby driving the second lifting cylinder 3 to make a reciprocating motion within the stroke range of the forward and reverse screws 15. When the suction cup 31 is fitted to the surface of the LCD display screen, the first lifting cylinder 21 drives the LCD display screen to move onto the detection board 4. At this time, the third lifting cylinder 32 drives the detector 33 to detect the LCD display screen on the detection board 4. When the LCD display screen is detected to have a fault, the indicator light 34 flashes and the speaker 35 alarms. At this time, the suction cup 31 moves the faulty LCD display screen to the waste box 6 for placement. When the LCD display screen is detected to be normal and can be put into use, the suction cup 31 moves the good LCD display screen to the storage box 5 for placement.

[0031] The working principle of the above embodiment is:

[0032] In the first step, when the staff places the LCD display screen to be inspected on the two second slide rails 28, the LCD display screen slides downward to the first slide rail 27 due to the action of gravity. Under the action of the limit plate 25, the LCD display screen is stationary on the first slide rail 27 and is located above the carrier plate 22. At this time, the output end of the first lifting cylinder 21 drives the carrier plate 22 to stretch upward. When the LCD display screen is located between the two opposite telescopic plates 242, the upward thrust brought to the LCD display screen by the first lifting cylinder 21 presses the telescopic plate 242 to go deeper into the storage block 24, thereby driving the spring 241 is compressed. When the height of the LCD display screen rises higher than the upper surface of the first group of storage blocks 24, the output end of the first lifting cylinder 21 contracts back. At this time, the spring 241 restores its own shape to give an outward elastic force to the telescopic plate 242 to make the telescopic plate 242 extend outward, and then the LCD display screen can fall back to the upper surface of the first group of telescopic plates 242 under the action of gravity. Similarly, when the first lifting cylinder 21 pushes the next LCD display screen to be inspected to the upper surface of the first group of telescopic plates 242, it can drive the first LCD display screen to be pushed to the upper surfaces of the second and third groups of telescopic plates 242.

[0033] In the second step, after the LCD display screen is pushed to the upper surface of the third group of telescopic plates 242, the second lifting cylinder 3 drives the suction cup 31 to fit the surface of the LCD display screen, and under the action of the reciprocating motor 13, drives the forward and reverse screws 15 to rotate, and with the cooperation of the limit rod 16, the slider 17 makes a reciprocating motion within the stroke range of the forward and reverse screws 15, thereby driving the second lifting cylinder 3 to make a reciprocating motion within the stroke range of the forward and reverse screws 15. After the suction cup 31 is fitted with the surface of the LCD display screen, the first lifting cylinder 21 drives the LCD display screen to move onto the detection board 4. At this time, the third lifting cylinder 32 drives the detector 33 to detect the LCD display screen on the detection board 4. When the LCD display screen is detected to have a fault, the indicator light 34 flashes and the speaker 35 alarms. At this time, the suction cup 31 moves the faulty LCD display screen to the waste box 6 for placement. When the LCD display screen is detected to be normal and can be put into use, the suction cup 31 moves the good LCD display screen to the storage box 5 for placement.
