Description

Technical Field

[0001] This utility model relates to the field of display screen dispensing technology, and in particular to a display screen dispensing machine. Background Technology

[0002] A display screen, a type of flat panel display, is commonly used in televisions and computers. Over the years, with the development of industries such as telecommunications, display screens have become ubiquitous and are now an indispensable product in daily life and work.

[0003] Currently, during the production of displays, it is necessary to apply adhesive (such as conductive adhesive dots) to the displays. However, current dispensing machines can only produce adhesive dots of one size. In the dispensing process of displays, the required adhesive dot size varies for different parts of the display or for different specifications of the display, which existing dispensing machines cannot meet.

[0004] Secondly, before dispensing, the display screen needs to be dusted to ensure the dispensing effect. However, the existing dust removal mechanism on the display screen can only remove dust from the display screen itself. During the dispensing process, adhesive residue will remain on the conveyor belt used to transport the display screen. When the adhesive solidifies, it will form adhesive lumps on the conveyor belt, which will not only affect the stable placement of the display screen, but also affect the transmission effect of the conveyor belt.

[0005] In conclusion, improvements are needed. Utility Model Content

[0051] The body consists of a lower body 100 and an upper body 102 connected to the lower body 100 via a bracket 101;

[0052] The conveyor belt consists of a first conveyor belt 103 and a second conveyor belt 104 installed on the lower body 100 and spaced apart. The first conveyor belt 103 and the second conveyor belt 104 are respectively used to carry and transport the display screen.

[0053] The dispensing device consists of at least two sets of dispensing structures and a drive structure that controls the reciprocating movement of each set of dispensing structures.

[0054] Each dispensing structure includes a first dispensing head 21 and a second dispensing head 22 that are slidably connected to the upper body 102 and have different dispensing diameters. The first dispensing head 21 and the second dispensing head 22 can be supplied with glue by the glue delivery tube. Since the structure of the dispensing head is a very mature existing technology, it will not be described in detail in this embodiment.

[0055] The drive structure can drive the first glue head 21 or the second glue head 22 to slide and move the first glue head 21 or the second glue head 22 above the conveyor belt.

[0056] In this embodiment: the driving structure includes:

[0057] Several drive wheels 30 (four in this embodiment) are rotatably connected to the upper body 102 via a rotating shaft, and can be controlled by the first motor 31 to rotate clockwise or counterclockwise. The first motor 31 is mounted on the upper body 102.

[0064] like Figures 1-6 As shown, in this embodiment, a dust collection mechanism installed on the body (lower body 100) is also included, wherein the dust collection mechanism includes:

[0065] The chassis 40 is mounted on the body (lower body 100) and has at least two movable cavities 41, each with an open opening.

[0071] A fan 45 is installed on the body (upper body 102) and connected to the exhaust chamber 42b through a first dust extraction pipe 45d. In this embodiment, the upper body 102 is provided with a fan chamber 45a, and the fan 45 is located at the top of the fan body 45a. The dust extraction body and the slide rod 43a form a chamber inside, and the slide rod is provided with a connecting nozzle 43b that communicates with the chamber of the slide rod 43a. The connecting nozzle 43a is connected to the air inlet chamber 42a inside the box through a second dust extraction pipe 43c.

[0072] When the dust scraping structure moves out of the active cavity 41, the suction body 43 is controlled to move above the dust scraping structure.

[0073] In this embodiment: the dust scraping structure includes:

[0074] The dust scraper body 50 has a U-shaped cross-section and is slidably connected in the movable cavity 41;

[0075] Scraper 51 is mounted on dust scraper 50;

[0076] The chassis 40 is provided with a drive cavity 52, which is located on top of the movable cavity 41 and communicates with the movable cavity 41.

[0077] In this embodiment: the driving device includes:

[0078] Several pulleys 61 are rotatably connected to the machine body (upper machine body 102) via a rotating shaft, and can be controlled by the second motor 62 to rotate clockwise or counterclockwise;

[0079] The drive belt 63 is connected between the pulleys 61.

[0080] Several movable blocks are mounted on the transmission belt 63 and are located between adjacent pulleys 61.

[0081] The movable block consists of a first movable block 641 and a second movable block 642. The first movable block 641 is connected to the slide rod 43a of each vacuum body 43, and each second movable block 642 is provided with a linkage rod 644 that can move in the drive cavity 52 and is connected to the dust scraper 50.

[0082] In this embodiment, the linkage rod 644 is connected to the dust scraper body 50 by means of a reversing structure. The reversing structure consists of a first rack 71 and a second rack 72 slidably disposed in the drive cavity 52, and a gear 73 rotatably connected in the drive cavity 52 and located between the first rack 71 and the second rack 72. The gear 73 meshes with the first rack 71 and the second rack 72. The first rack 71 is connected to the linkage rod 644, and the second rack 72 is mounted on the dust scraper body 50.

[0083] In this embodiment: the top of the housing 40 is provided with a cleaning port communicating with the filter chamber, and an organic cover 8 is detachably connected to the cleaning port. The organic cover 8 is provided with an exhaust port 80 that is provided through and connected to the first dust extraction pipe. The exhaust port 80 is connected to the bottom end of the fan chamber 45a through the first dust extraction pipe.

[0084] In this embodiment: the movable cavity 41 is rotatably connected to a cleaning roller 9 that can be controlled by a third motor 93 near the cavity opening, and the cleaning roller 9 is provided with cleaning scrapers 91 that are circumferentially and equally spaced.

[0085] refer to Figures 1-6 The principle of this embodiment is:

[0086] During dust removal, the fan starts and drives the dust suction holes at the bottom of the dust suction body through the first dust suction pipe to remove dust from the display screen on the conveyor belt. The air intake principle is as follows: impurities enter the dust suction body through the dust suction holes and enter the air intake chamber through the second dust suction pipe. After being filtered by the filter screen, the air pressure enters the fan chamber through the first dust suction pipe and is discharged by the fan.

[0087] During the cleaning of the conveyor belt, the blower remains running, and the second motor controls the rotation of the pulley, thereby controlling the movement of the linkage rod and the suction body. When the linkage rod moves, the first rack drives the gear to rotate, and the second rack drives the dust scraper to move and move out of the movable chamber. After the dust scraper moves out, the scraper comes into contact with the conveyor belt. At this time, the suction body on the same side as the dust scraper also moves to above the dust scraper. When the conveyor belt moves, the impurities on the surface of the conveyor belt can be scraped off by the scraper and sucked away by the suction body, thus completing the cleaning of the conveyor belt.

[0088] During the cleaning process, as the drive unit propels the scraper into or out of the active chamber, the cleaning roller is controlled to rotate and uses the cleaning scraper to remove impurities from the scraper, thus completing the cleaning of the scraper. When the scraper is in the active chamber, the fan starts to introduce airflow from the top opening of the drive chamber and into the active chamber. The airflow then passes through the dust scraper to clean the dust scraper and carries impurities into the air intake chamber. The impurities are filtered by the filter screen and remain in the air intake chamber, thus completing the cleaning of the scraper.

[0089] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
