DETAILED DESCRIPTION

[0024] 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.

[0025] Embodiment 1: A liquid crystal display screen processing glue coating device, see Figure 1-Figure 3 As shown, it includes a placement table 1, a first electric slide rail 2, a movable plate 3, an installation cabinet 4, a motor 5 and a mounting block 6, and a gluing component. Two first electric slide rails 2 are installed on the placement table 1 by bolt connection. The two first electric slide rails 2 are jointly provided with a movable plate 3 for horizontal sliding. The movable plate 3 is installed with a mounting cabinet 4 by bolt connection. The motor 5 is installed in the mounting cabinet 4 by bolt connection. The output shaft of the motor 5 faces upward, and the output shaft of the motor 5 penetrates the top of the mounting cabinet 4 and is fixedly connected to the mounting block 6 by a key. The placement table 1 is provided with a gluing component for gluing a liquid crystal display screen, and also includes a first placement plate 7, an air pump 8 and an exhaust pipe 9. The first placement plate 7 is installed on the top of the mounting block 6 by bolt connection. The exhaust pipe 9 is connected and communicated with the first placement plate 7. The air pump 8 is installed in the first placement plate 7 by bolt connection, and the air pump 8 is connected to the exhaust pipe 9.

[0026] See also Figure 2 As shown, the glue coating assembly includes two second electric slide rails 10 embedded on both sides of the top of the placement table 1, and a third electric slide rail 11 is commonly arranged on the two second electric slide rails 10 in a horizontal sliding manner. A moving block 1101 is arranged on the third electric slide rail 11 in a horizontal sliding manner. A cylinder 1102 is installed on the moving block 1101 by bolt connection, and the push rod of the cylinder 1102 faces downward. The bottom of the push rod of the cylinder 1102 is fixedly connected to a glue gun 1103 by bolt connection.

[0027] When the LCD screen needs to be glued, the LCD screen is placed on the first placement plate 7, and then the air pump 8 is started. The air pump 8 draws air through the exhaust pipe 9 to adsorb and fix the LCD screen on the first placement plate 7, and then the first electric slide rail 2 is started to drive the movable plate 3 to move to the gluing area, and then the second electric slide rail 10 is started to drive the third electric slide rail 11 to move horizontally, and the third electric slide rail 11 is started to drive the moving block 1101 to move horizontally, so that the moving block 1101 drives the cylinder 1102 and the glue gun 1103 to move and align with the LCD screen, and then the glue gun 1103 is pushed downward by the cylinder 1102 to move close to the LCD screen, and the LCD screen is glued by the glue gun 1103.

[0028] Example 2: Based on Example 1, refer to Figure 2 and Figure 5 As shown, it also includes a first mounting frame 12 installed on both sides of the middle part of the placement table 1 by bolt connection. The first mounting frame 12 is located on the side where the two first electric slide rails 2 are away from each other. The first mounting frame 12 is fixedly connected with a first guide rod 13 by welding. A moving rod 14 is commonly provided on the two first guide rods 13 in a transverse sliding manner. A first elastic member 16 for pushing the moving rod 14 to slide and reset is wound around the first guide rod 13. A sponge pad 15 for wiping the LCD screen is installed at the bottom of the moving rod 14 by bonding.

[0029] When applying glue to the LCD screen, it is necessary to ensure that there is no stain or dust on the LCD screen to avoid affecting the adhesiveness. After the LCD screen is adsorbed on the first placement plate 7 by the air pump 8, the moving rod 14 is pushed to slide laterally along the first guide rod 13. At this time, the first elastic member 16 is compressed and deformed by force, so that the sponge pad 15 contacts and wipes the surface of the LCD screen to remove dust and stains on the surface of the LCD screen. After the moving rod 14 is released, the first elastic member 16 pushes the moving rod 14 to slide and reset.

[0030] See also Figure 6 As shown, it also includes a mounting cover 17 installed on the top of the placement table 1 by means of bolt connection, an electric heating pipe 18 is installed in the mounting cover 17 by means of bolt connection, and a protective net 19 is installed at the bottom of the mounting cover 17 by means of bolt connection.

[0031] After the LCD screen is coated with glue, it needs to be glued to other components. In order to prevent the glue from drying out too quickly, the electric heating tube 18 is started to insulate the glue on the LCD screen after coating, so that the glue is in a liquid state. The protective net 19 can prevent foreign matter from contacting the electric heating tube 18 to avoid combustion and fire. The installation cover 17 can reduce the heat loss of the electric heating tube 18.

[0032] See also Figure 7 As shown, it also includes second mounting frames 20 installed on both sides of the placement table 1 by bolt connection. The two second mounting frames 20 are located on the side where the two first electric slide rails 2 are away from each other. Two second guide rods 21 are arranged on the second mounting frames 20 in a transverse sliding manner. The two second guide rods 21 are fixedly connected with clamping plates 22 by welding. The two sides of the two clamping plates 22 form an outwardly open and symmetrical figure eight shape to facilitate the LCD screen to be pushed into between the two clamping plates 22. Three scrapers 23 for scraping off the overflow glue on the edge of the LCD screen are embedded and installed on the side where the two clamping plates 22 are close to each other. A second elastic member 24 for pushing the clamping plates 22 on both sides to approach each other is wound around the second guide rod 21.

[0033] After the LCD screen is coated with glue, glue overflow may occur, resulting in glue blocks on the edge of the LCD screen. At this time, the first electric slide rail 2 drives the movable plate 3 to slide continuously, so that the LCD screen on the first placement plate 7 moves and pushes the clamping plates 22 on both sides, so that the clamping plates 22 slide toward the side away from each other through the second guide rod 21 along the second mounting frame 20. At this time, the second elastic member 24 is compressed and deformed by force, and the second elastic member 24 provides a thrust for the clamping plates 22 on both sides to fit the LCD screen on the first placement plate 7, so that the edges of the LCD screen rub against the scraper 23 when the LCD screen moves, so that the scraper 23 scrapes off the glue overflowing from the edge of the LCD screen. When the LCD screen passes over the two clamping plates 22, the motor 5 drives the first placement plate 7 to rotate 90 degrees through the mounting block 6, so that the LCD screen rotates 90 degrees, and the first electric slide rail 2 drives the movable plate 3 to slide in the opposite direction, so that the other two sides of the LCD screen contact with the scraper 23 to scrape off the overflowed glue.

[0034] See also Figure 4 and Figure 7 As shown, a telescopic sleeve 25 is sleeved on the second guide rod 21, and the second elastic member 24 is located in the telescopic sleeve 25; a second placement plate 26 is installed on the side of the dispensing gun 1103 by bolt connection, and a wiping block 27 is placed on the second placement plate 26.

[0035] The telescopic sleeve 25 is telescopic and retractable with the sliding of the second guide rod 21. The telescopic sleeve 25 is used to protect the second elastic member 24 to prevent the second elastic member 24 from being damaged. After the glue gun 1103 dispenses glue, there may be glue remaining at its glue outlet, which may easily affect the next use after the glue is dry and hard. After the glue gun 1103 has finished dispensing glue, remove the wiping block 27 in time to wipe off the glue remaining at the glue outlet of the wiping block 27, and then place the wiping block 27 back on the second placement plate 26.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
