One end fixed mounting that first drive plate 21 was kept away from to second drive plate 22 has mount pad 211, the inside of mount pad 211 is embedded to have first servo motor 213, first servo motor 213 rotates the one side that extends to mount pad 211 through the power shaft, and fixed mounting has transmission fluted disc 23, first servo motor 213 provides power, it rotates to drive transmission fluted disc 23, the inside bottom lateral wall and the left and right sides lateral wall of rectangle driving groove 12 all are equipped with transmission tooth piece 14, transmission fluted disc 23 is located rectangle driving groove 12, and with the meshing of transmission tooth piece 14, transmission fluted disc 23 can roll along bottom lateral wall and both sides lateral wall in rectangle driving groove 12, drive second drive plate 22 and the swing of first drive plate 21, the realization covers whole mounting groove 13.
First drive plate 21 and second drive plate 22 lateral wall fixed mounting have a cleaning adhesive tape 26 that is used for clean LCD 11, after LCD 11 adjusts backward along mounting groove 13, transmission fluted disc 23 begins to rotate from one side top of rectangle driving groove 12, rotate to the opposite side top of rectangle driving groove 12, telescopic connection between first drive plate 21 and the second drive plate 22, and swing 180 in step, to 11 surperficial full coverings of LCD, utilize cleaning adhesive tape 26 to carry out cleaning operation to 11 surperficial dusts of LCD, make 11 surperficial clean of LCD, the screen display is clear, the best effect.
How flexible problem between first fan-shaped transfer line 27 and the second fan-shaped transfer line 28, the inside embedded second servo motor 214 that has kept away from the one end of first transfer board 21 of second transfer board 22, useful rectangle breach 210 is seted up to second transfer board 22, inside second servo motor 214 rotated through the power shaft and extended to corresponding rectangle breach 210, and fixedly connected with two mutual symmetric distribution's first fan-shaped transfer line 27, second servo motor 214 provided power, drove first fan-shaped transfer line 27 and rotated.
Two second fan-shaped transmission rods 28 which are symmetrically distributed with each other are rotatably mounted on the inner side wall of the rectangular notch 210 of the first transmission plate 21, the second fan-shaped transmission rods 28 are distributed with the first fan-shaped transmission rods 27 in a staggered manner, as shown in fig. 5, and the two first fan-shaped transmission rods 27 and the two second fan-shaped transmission rods 28 form transmission rods with cylindrical structures, the second fan-shaped transmission rods 28 rotate on the inner side wall of the rectangular notch 210 of the first transmission plate 21, the second fan-shaped transmission rods 28 and the first fan-shaped transmission rods 27 are distributed in a staggered manner and form transmission rods with cylindrical structures, when the first fan-shaped transmission rods 27 rotate, the second fan-shaped transmission rods 28 can be synchronously driven to rotate, i.e. the transmission rod of cylindrical configuration rotates, and the extension between the second sector transmission rod 28 and the first sector transmission rod 27 can in turn meet the difference in the number of the extensions between the first transmission plate 21 and the second transmission plate 22.
The outside cover of the transfer line of cylindrical structure has the clean seat 24 of rectangle that can slide along rectangle breach 210 inside through the external screw thread rotation, and second fan-shaped transfer line 28 constitutes cylindrical structure's transfer line with first fan-shaped transfer line 27, can be driven by second servo motor 214 and rotate, but the clean seat 24 of rectangle passes through the screw hole and can translate along rectangle breach 210 inside, realizes the adjustment operation to the clean seat 24 position of rectangle to in clean operation.
The second fan-shaped transmission rod 28 and the first fan-shaped transmission rod 27 can form a cylindrical surface independently, and can drive the rectangular cleaning seat 24 to move on the second fan-shaped transmission rod 28 and the first fan-shaped transmission rod 27, so that the telescopic rods of the second fan-shaped transmission rod 28 and the first fan-shaped transmission rod 27 can complete the extension and contraction and can drive the rectangular cleaning seat 24 to move at the same time. This problem is avoided by the design, and the second fan drive link 28 and the first fan drive link 27 form a complete cylinder, which allows for a more stable drive.
The groove 212 has been seted up to the clean seat 24 lateral wall of rectangle, and the internally mounted who accomodates groove 212 has the mechanism 3 that strikes off that is used for striking off LCD liquid crystal display 11, in order to clear up the birds excrement and urine dirt on LCD liquid crystal display 11 surface, utilizes the mechanism 3 that strikes off to follow the synchronous adjustment of the clean seat 24 position of rectangle, and the clean seat 24 available mechanism 3 that strikes off of place of rectangle is cleared up the operation to birds excrement and urine dirt.
Among the prior art, at present, the mode of effectively clearing up to 11 surperficial birds excrement and urine of LCD liquid crystal display has not yet been adopted, how only adopt adhesive tape 26 to carry out cleaning operation to 11 surperficial dust of LCD liquid crystal display, also can only clean 11 surperficial dust of LCD liquid crystal display, and can not reach the purpose of scraping off birds excrement and urine, birds excrement and urine is than harder after air-drying in addition, adopts adhesive tape 26 to clean, can cause the damage to adhesive tape 26.
When birds excrement is on a certain position of the surface of the LCD (liquid crystal display) 11, the first transmission plate 21 and the second transmission plate 22 are adjusted to be opposite to the position of the dirt position, the second servo motor 214 is used for controlling the second fan-shaped transmission rod 28 and the first fan-shaped transmission rod 27 to form a transmission rod with a cylindrical structure to rotate, the rectangular cleaning seat 24 can be driven to axially adjust the position along the transmission rod with the cylindrical structure, namely the rectangular cleaning seat 24 can horizontally move along the inside of the rectangular notch 210, the adjustment operation of the position of the rectangular cleaning seat 24 is achieved, the rectangular cleaning seat 24 is moved to the dirt position to stop adjusting, the scraper 34 is rotated to scrape the birds excrement, the scraper 34 is used for replacing the cleaning rubber strip 26 to clean the birds excrement, on one hand, the service life of the cleaning rubber strip 26 is prolonged, and on the other hand, the birds excrement can be completely cleaned.
Example two
Referring to fig. 1-7, a further improvement is made on the basis of embodiment 1:
in order to solve the problem how to attach the scraper 34 to the LCD 11 in real time during the scraping operation, a first hollow electromagnet disc 35 is embedded in a side wall of the inside of the receiving groove 212, which is far away from the opening, and a second hollow electromagnet disc 36, which is opposite to the first hollow electromagnet disc 35, is fixedly mounted at one end of the outer wall of the drawing cylinder 33, which is close to the rectangular top bar 32, to supply power to the first hollow electromagnet disc 35 and the second hollow electromagnet disc 36, so that when the opposite side wall poles of the first hollow electromagnet disc 35 and the second hollow electromagnet disc 36 are the same, repulsive force can be generated, the drawing cylinder 33 can be pushed out of the receiving groove 212, i.e. the scraper 34 is pushed out and attached to the LCD 11 in real time, thereby ensuring the effective scraping operation of the scraper 34.
The mode that the mode of artifical ascending a height was adopted to LCD liquid crystal display 11 surface dust in the tradition cleared up increases the potential safety hazard of the operation of ascending a height of workman on the one hand, and on the other hand can't frequently clear up LCD liquid crystal display 11.
According to 11 surface cleanliness of LCD liquid crystal display, can be at any time automatic start clean mechanism 2, carry out quick clearance operation to 11 surface dust of LCD liquid crystal display and birds excrement and urine dirt, replace the manpower to improve clean efficiency.
