DETAILED DESCRIPTION

[0019] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0020] Example 1 A dispensing packaging equipment for the production of vehicle display screens, such as Figure 1-Figure 8 As shown, it includes a box body 1, an electric guide rail 2, a regulator 3, a moving block 4, a cylinder 5, a clamp 6 and a dispensing head 9; the box body 1 is bolted to the electric push rod 101; the box body 1 is fixedly connected to the electric guide rail 2; the electric guide rail 2 is connected to the regulator 3; the regulator 3 is connected to the dispensing head 9; the electric guide rail 2 is slidably connected to the moving block 4; the moving block 4 is fixedly connected to the cylinder 5, and the telescopic end of the cylinder 5 is provided with an electric suction cup; the box body 1 is fixedly connected to two clamps 6 for fixing the frame body 7; It also includes a push plate 103, a round rod 104, a lifting assembly and a driving assembly; the box body 1 is connected to the lifting assembly; the lifting assembly is connected to the push plate 103, and the lifting assembly is used to drive the push plate 103 and the parts thereon to move vertically; the push plate 103 is connected to a plurality of high temperature resistant round rods 104, and the number and position of the round rods 104 correspond to the round holes 71 on the frame body 7; the push plate 103 is connected to a driving assembly for driving the round rods 104 to rotate, and the driving assembly is connected to the round rods 104; the lifting assembly consists of an electric push rod 101, a connecting plate 102, and a spring plate 20 6. It is composed of a rectangular plate 207, a baffle plate 208 and a hollow tube 209; the box body 1 is bolted to the electric push rod 101; the telescopic end of the electric push rod 101 is slidably connected to the connecting plate 102, and the connecting plate 102 is fixedly connected to the push plate 103; the box body 1 is fixedly connected to the spring plate 206, and the telescopic end of the spring plate 206 is fixedly connected to the connecting plate 102; the telescopic end of the electric push rod 101 is fixedly connected to the rectangular plate 207; the push plate 103 is slidably connected to the baffle plate 208, and the baffle plate 208 is fixedly connected to the telescopic end of the electric push rod 101; the baffle plate 208 is fixedly connected to the hollow tube 209.

[0021] The driving assembly includes a motor 107, a belt 108, a pulley 109 and a rotating rod 1010; the push plate 103 is rotatably connected to the round rod 104; the push plate 103 is rotatably connected to four rectangularly distributed rotating rods 1010; the push plate 103 is bolted to the motor 107, and the output shaft of the motor 107 is fixedly connected to one of the rotating rods 1010; each round rod 104 is fixedly connected to a pulley 109; all the rotating rods 1010 are wrapped with a belt 108, and the belt 108 passes around all the pulleys 109.

[0022] The round rod 104 and the push plate 103 are detachably connected. When different frames 7 are packaged and glued, the round rod 104 is adaptively replaced to make the round rod 104 adapt to the circular holes 71 of different diameters, thereby improving the adaptability.

[0023] When in use, the clamp 6 is opened manually, and the frame 7 to be packaged is fixed on the two clamps 6. Then, the electric push rod 101 is controlled to move the rectangular plate 207 upward, and then the connecting plate 102 drives the push plate 103 to move the round rod 104 upward along the round hole 71 under the elastic force of the spring plate 206, until the top of the round rod 104 exceeds the upper side of the round hole 71. Figure 5 As shown, the upper side of the circular hole 71 is first blocked by the round rod 104, and then the electric guide rail 2 is controlled to make the regulator 3 drive the dispensing head 9 to move close to the upper side of the frame 7. At the same time, the dispensing head 9 is controlled to inject hot melt adhesive into the upper side of the frame 7. Then, the cylinder 5 is controlled to make the electric suction cup suck up the screen assembly 8, and then the electric guide rail 2 is controlled to make the moving block 4 drive the cylinder 5 to move to the left until the screen assembly 8 is located directly above the frame 7. Then, the cylinder 5 is controlled to make the electric suction cup drive the screen assembly 8 to move downward, and the screen assembly 8 squeezes the round rod 104. When the round rod 104 drives the push plate 103 to move downward, it drives the connecting plate 102 to squeeze the spring plate 206 downward, and the spring plate 206 is adaptively compressed. The adaptive compression of the spring plate 206 can prevent the screen assembly 8 from being broken by the round rod 104 when it moves downward, so that the top of the round rod 104 is flush with the upper side of the circular hole 71, and then The screen assembly 8 is pressed onto the upper side of the frame 7. During the pressing process, the hot melt adhesive on the frame 7 is squeezed by the screen assembly 8 and flows into the circular hole 71 area. Since the round rod 104 blocks the upper area of ​​the circular hole 71, the hot melt adhesive is effectively prevented from being squeezed into the circular hole 71. After the pressing is completed, the control driving assembly drives the round rod 104 to rotate, so that the round rod 104 removes the glue in the upper area of ​​the circular hole 71 to prevent the glue from affecting the subsequent use of the circular hole 71. Then, the clamp 6 is manually opened, and the pressed frame 7 and screen assembly 8 are taken upward along the round rod 104, so that the round rod 104 withdraws from the circular hole 71. Subsequently, the glue attached to the round rod 104 is manually wiped off. After the pressed frame 7 and screen assembly 8 move up and away from the round rod 104, the push plate 103 and the round rod 104 move upward under the rebound force of the spring plate 206.

[0024] The steps of the driving component are: control the motor 107 to start, drive the rotating rod 1010 through the output shaft of the motor 107, the rotating rod 1010 drives the belt 108 to rotate, the belt 108 drives the pulley 109 to rotate through friction, and the pulley 109 drives the corresponding round rod 104 to rotate.

[0025] After the screen assembly 8 is pressed together with the frame 7 by the hot melt adhesive, the frame 7 and the screen assembly 8 can be firmly bonded only after the hot melt adhesive is cooled and solidified. Therefore, after the round rod 104 exits the round hole 71, the electric push rod 101 is controlled to drive the rectangular plate 207, the baffle 208 and the hollow tube 209 to move upward until the baffle 208 completely covers the lower side of the frame 7. At this time, the frame 7, the screen assembly 8 and the baffle 208 together form a relatively closed space, such as Figure 8 As shown, then, the external air pump is controlled to start, and cold air is input into the space formed by the frame 7, the screen assembly 8 and the baffle 208 through the hollow tube 209, thereby increasing the cooling and curing speed of the hot melt adhesive and improving production efficiency.

[0026] Example 2 On the basis of Example 1, Figure 1 and Figure 3-Figure 8 As shown, it also includes a connecting pipe 201, an air delivery pipe 202, a connecting ring 203, a rubber ring 2010, a connecting rod 2011 and a plug 2012; the round rod 104 is hollow; each round rod 104 is connected to a high-temperature resistant rubber ring 2010 on the upper side to prevent the rubber ring 2010 from being thermally deformed when the high-temperature glue sprayed by the dispensing head 9 is sprayed on the rubber ring 2010; each round rod 104 is slidably connected to a connecting rod 2011; each connecting rod 2011 is fixedly connected to a rounded A trapezoidal plug 2012 is provided, and the plug 2012 is connected to the corresponding rubber ring 2010; the push plate 103 is fixedly connected to a connecting pipe 201; the push plate 103 is fixedly connected to a plurality of gas pipes 202, and the gas pipes 202 are connected to the corresponding round rods 104, and the gas pipes 202 are connected to the connecting pipe 201; each gas pipe 202 is fixedly connected to a connecting ring 203; each round rod 104 is provided with a plurality of gas holes 1001, and the connecting ring 203 is connected to the corresponding round rod 104 through the gas holes 1001.

[0027] It also includes a scraper 1011; each rubber ring 2010 is fixedly connected to a plurality of scrapers 1011. After the screen assembly 8 is attached to the upper side of the frame 7 coated with hot melt adhesive, the round rod 104 rotates in the round hole 71 to drive the connecting rod 2011, the plug 2012, the rubber ring 2010 and the scraper 1011 to rotate, so that the scraper 1011 scrapes off the glue located in the area of ​​the round hole 71, thereby improving the efficiency of the round rod 104 in removing the glue in the upper area of ​​the round hole 71.

[0028] The round rod 104 and the rubber ring 2010 are detachably connected. Since the rubber ring 2010 needs to be in contact with the hot melt adhesive, the rubber ring 2010 is easily worn and needs to be replaced in time. The detachable connection of the rubber ring 2010 facilitates the timely replacement of the rubber ring 2010.

[0029] It also includes spring rods 204 and gaskets 205 ; the push plate 103 is fixedly connected with a plurality of spring rods 204 ; the telescopic end of each spring rod 204 is fixedly connected with a gasket 205 , and the gasket 205 is rotatably connected with the corresponding round rod 104 .

[0030] The external air pump is connected to the connecting pipe 201, and the external air delivery pump is connected to the hollow pipe 209. When the round rod 104 moves upward along the round hole 71 to block the round hole 71, there is a gap between the round rod 104 and the inner wall of the round hole 71, so that part of the glue will flow into the gap between the round rod 104 and the inner wall of the round hole 71, resulting in the phenomenon of glue residue in the round hole 71. Therefore, when the round rod 104 moves upward along the round hole 71, the rubber is driven The ring 2010, the connecting rod 2011 and the plug 2012 are moved upward until the upper part of the rubber ring 2010 is flush with the upper side of the circular hole 71. Then, the external air pump is controlled to pump air into the air delivery pipe 202 through the connecting pipe 201. The air delivery pipe 202 pumps air into the round rod 104, so that the connecting rod 2011 drives the plug 2012 to slide downward in the round rod 104 under the action of negative pressure, so that the inverted truncated cone-shaped plug 2012 opens the rubber ring 2010. Figure 6 As shown, the rubber ring 2010 is closely fitted to the inner wall of the circular hole 71 , preventing the glue from entering the circular hole 71 through the gap between the rubber ring 2010 and the circular hole 71 .

[0031] As the round rod 104 drives the connecting rod 2011, the plug 2012, the rubber ring 2010 and the scraper 1011 to rotate so that the rubber ring 2010 and the scraper 1011 remove the glue in the area of ​​the circular hole 71, in order to avoid wear of the inner wall of the circular hole 71 caused by the rotation of the round rod 104, the round rod 104 does not contact the inner wall of the circular hole 71, so that the rubber ring 2010 and the scraper 1011 located at the end of the round rod 104 are unstable when the inner wall of the circular hole 71 rotates. Therefore, when the frame 7 is placed on the clamp 6 and the round rod 104 is inserted into the circular hole 71, after the frame 7 contacts the gasket 205, the frame 7 squeezes the gasket 205 downward, and the spring rod 204 is stretched. Since the gasket 205 contacts the frame 7, the stability of the round rod 104 during rotation is improved.

[0032] Example 3 On the basis of Example 2, Figure 4-Figure 5As shown, a micro pump 301 and a delivery pipe 302 are also included; the nozzle 91 located on the dispensing head 9 is fixedly connected with the micro pump 301 ; the micro pump 301 is connected with the delivery pipe 302 .

[0033] The delivery pipe 302 is arranged at an angle, so that the delivery pipe 302 blows the dust to a side away from the nozzle 91 , thereby protecting the nozzle 91 and preventing the dust from being blown to the nozzle 91 .

[0034] During normal glue injection, the micro pump 301 is controlled to start and deliver gas to the delivery pipe 302, and then the dust and impurities on the upper side of the frame 7 to be injected with glue are blown away through the delivery pipe 302, so that the upper side of the frame 7 is kept clean and the bonding effect between the frame 7 and the screen assembly 8 is improved.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
