Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, the present invention provides a cleaning device for a heating plate support hole, comprising a heating plate mechanism 3, and further comprising:

[0029] A cleaning mechanism 1, wherein the cleaning mechanism 1 is arranged above the heating plate mechanism 3;

[0030] Among them, the cleaning mechanism 1 includes a rotating drum 101, a cleaning head 102, a spray hole 103, an arc groove 104, a brush 105, a scraper 106 and a threaded groove 107. The bottom of the cleaning head 102 is provided with a spray hole 103 for spraying airflow, and the side of the cleaning head 102 is evenly provided with a plurality of arc grooves 104 for spraying airflow. The inside of the rotating drum 101 is provided with a threaded groove 107 for changing the direction of airflow. The surface of the cleaning head 102 is fixedly connected with a plurality of brushes 105 for cleaning dust, and both sides of the cleaning head 102 are fixedly connected with scrapers 106 for cleaning adhesives.

[0031] The bottom of the rotating drum 101 is fixedly connected to the top of the cleaning head 102, and the top of the injection hole 103 is communicated with the thread groove 107. The shapes of the injection hole 103 and the cleaning head 102 are both conical. The cross-section of the bottom of the injection hole 103 is smaller than the cross-section of the top of the injection hole 103. Several arc grooves 104 penetrate the surface of the cleaning head 102 and extend to the inside of the injection hole 103. The arc direction of the arc groove 104 away from the side of the injection hole 103 is the same as the downward advancing direction of the thread groove 107. Several arc grooves 104 and several brushes 105 are staggered. The side and top of the rotating drum 101 are fixedly connected to the limiting block 109. The interior of the rotating drum 101 is fixedly connected to the conical block 108 through the connecting frame. The conical block 108 is located inside the thread groove 107, and the vertex of the conical block 108 is upward. The thread groove 107 penetrates the inner wall of the rotating drum 101 and extends to the top of the rotating drum 101.

[0032] The above scheme is adopted: by setting the coordination of structures such as the brush 105 and the injection hole 103, it is convenient to clean different types of attachments, and pressurized gas is injected into the main shell 201 and the inside of the drum 101 through the gas injection pipe 205, and the device is moved downward to move the cleaning head 102 to the inside of the support hole 302. After the airflow passes through the main shell 201 and enters the inside of the drum 101, it will first be blocked by the conical block 108 and dispersed in the direction close to the inner wall of the thread groove 107, changing the direction of the airflow and making it flow downward in the direction of the thread groove 107. When the airflow flows to the injection hole 103, part of the airflow will be discharged from the side of the cleaning head 102 through the arc groove 104, and the stress exerted by the pressurized gas on the inner wall of the arc groove 104 drives the cleaning head 102 to rotate at the bottom of the main shell 201. The other part of the airflow will be discharged from the bottom of the cleaning head 102 through the injection hole 103 to blow away the dust deep in the support hole 302, and the rotating cleaning head 102 will clean the hole wall through the soft brush 105 on its side. When chemical reagents, adhesives and other attachments are attached to the inner wall of the support hole 302, the device can be moved in the direction close to the attachment to squeeze the brush 105 and make the scraper 106 fit the inner wall of the support hole 302, thereby increasing the cleaning force of the brush 105 on the area and scraping off the attachment through the scraper 106. Different types of dirt on the inner wall of the support hole, whether it is dust or chemical reagents, adhesives and other attachments, can be effectively dealt with, and the problem that the cleaning device is difficult to reach the dirt deep in the support hole is solved, ensuring that the entire depth range of the support hole can be cleaned.

[0033] like Figures 1 to 5As shown, the cleaning mechanism 1 is arranged inside the main body mechanism 2, and the main body mechanism 2 includes a main shell 201, and the inner wall of the main shell 201 is provided with a limiting groove 202, the bottom of the main shell 201 is fixedly connected with an adsorption ring 203, the surface of the main shell 201 is provided with a hand-holding area 204, and the top of the main shell 201 is fixedly connected with an air injection pipe 205, the hand-holding area 204 is located between the air injection pipe 205 and the adsorption ring 203, the interior of the air injection pipe 205 is communicated with the interior of the main shell 201, and the material of the adsorption ring 203 is an electrostatic adsorption material.

[0034] The rotating drum 101 is rotatably connected to the inner wall of the main shell 201, and the rotating drum 101 is rotatably connected to the limiting groove 202 through two limiting blocks 109. The adsorption ring 203 is rotatably sleeved on the outer side of the cleaning head 102. The adsorption ring 203 is located above the scraper 106 and the brush 105. The interior of the air injection pipe 205 is communicated with the threaded groove 107. The heating plate mechanism 3 includes a heating plate body 301. Four support holes 302 are evenly opened on the heating plate body 301. The shape of the support holes 302 is conical, and the size of the cleaning head 102 is smaller than the size of the support holes 302.

[0035] The above scheme is adopted: by setting the coordination of the arc groove 104 and the adsorption ring 203 and other structures, the cleaning effect of the device is improved. In this process, the airflow discharged through the arc groove 104 will also sweep the inner wall of the support hole 302, so that the dust inside the support hole 302 is fully blown up. When the dust is swept out of the support hole 302, it will move to the bottom of the adsorption ring 203. At this time, the adsorption ring 203 will adsorb the dust and debris generated during the cleaning process through electrostatic adsorption, ensuring that the pollutants will not fall back into the support hole, avoiding the residue and re-attachment of dirt in the support hole during the cleaning process, reducing the possibility of secondary pollution, and cooperating with the brush 105 to further improve the cleaning effect of the device. Cleaning effect, and a plurality of arc grooves 104 and a plurality of brushes 105 are staggeredly arranged, and the brush 105 can be purged by the airflow ejected from the arc groove 104 to prevent dust from adhering to the brush 105, thereby achieving the effect of self-cleaning of the device, which is convenient for the staff to use, and prevents the dust attached to the brush 105 from polluting the cleaned support hole 302, thereby ensuring the cleaning quality of the support hole 302, so that each support hole 302 can be thoroughly cleaned, which is beneficial to improving the performance and product quality of the LCD TV heating plate, and reducing the damage of the dust to the brush 105, thereby extending the service life of the brush and reducing the maintenance cost of the cleaning device.

[0036] The working principle and use process of the present invention are as follows: first, the main body 301 of the LCD TV heating plate to be cleaned is placed with the support hole 302 facing upwards, and then the staff needs to hold the handhold area 204 to pick up the device, and then align the cleaning head 102 at the bottom of the device with the support hole 302. At this time, pressurized gas is injected into the main body shell 201 and the inside of the rotating drum 101 through the gas injection pipe 205, and the device is moved downward to move the cleaning head 102 to the inside of the support hole 302. After the airflow passes through the main body shell 201 and enters the inside of the rotating drum 101, it will first be blocked by the conical block 108 and dispersed in the direction close to the inner wall of the thread groove 107, changing the direction of the airflow and making it flow downward along the direction of the thread groove 107. When the airflow flows to the injection hole 103, a part of it The airflow will be discharged from the side of the cleaning head 102 through the arc groove 104, and the stress exerted by the pressurized gas on the inner wall of the arc groove 104 drives the cleaning head 102 to rotate at the bottom of the main shell 201, while another part of the airflow will be discharged from the bottom of the cleaning head 102 through the injection hole 103 to blow away the dust deep in the support hole 302, and the rotating cleaning head 102 will clean the hole wall through the soft brush 105 on its side, and when the inner wall of the support hole 302 is attached with chemical reagents, adhesives and other attachments, the device can be moved in the direction close to the attachment to squeeze the brush 105 and make the scraper 106 fit with the inner wall of the support hole 302, thereby increasing the cleaning force of the brush 105 on the area and scraping off the attachment through the scraper 106;

[0037] During this process, the airflow discharged through the arc groove 104 will also sweep the inner wall of the support hole 302, so that the dust inside the support hole 302 is fully blown up. When the dust is swept out of the support hole 302, it will move to the bottom of the adsorption ring 203. At this time, the adsorption ring 203 will use electrostatic adsorption to adsorb dust and debris generated during the cleaning process to ensure that pollutants will not fall back into the support hole, thereby completing the cleaning of the support hole 302 on the heating plate body 301. At the same time, a plurality of arc grooves 104 and a plurality of brushes 105 are staggered and distributed, and the arc grooves can be used to clean the dust and debris. The airflow ejected by 104 sweeps the brush 105 to prevent dust from adhering to the brush 105, achieving a self-cleaning effect, which is convenient for the staff to use and prevents the dust adhering to the brush 105 from contaminating the cleaned support hole 302, thereby ensuring the cleaning quality of the support hole 302, so that each support hole 302 can be thoroughly cleaned, which is beneficial to improving the performance and product quality of the LCD TV heating plate, and reducing the damage of dust to the brush 105, thereby extending the service life of the brush and reducing the maintenance cost of the cleaning device.
