[0030] Please refer to Figures 1 to 4 , which is the feeding and conveying device in the embodiment of this utility model, including a conveying mechanism and a dust removal mechanism.

[0031] Among them: The conveying mechanism is used to convey the backlight module. The conveying device includes a workbench 10 and a conveyor belt 11 arranged on the workbench 10. The conveyor belt 11 is driven by a driving member, which is a prior art and will not be elaborated herein; The dust removal mechanism is used to remove dust from the backlight module. The dust removal mechanism includes an isolation cover 21, a air supply component and a dust suction component arranged on the workbench 10. The isolation cover 21 surrounds the conveyor belt 11. The isolation cover 21 is used to isolate part of the dust or other impurities on the backlight module on the conveyor belt 11. The cross-section of the isolation cover 21 is an arch structure. A feeding channel 22 is connected to the isolation cover 21. The feeding channel 22 communicates with the isolation cover 21. Specifically, a through slot is opened on the isolation cover 21, and the through slot penetrates the isolation cover 21. One end opening of the feeding channel 22 is connected to the through slot. It should be noted that the feeding channel 22 is a frame structure, and the cross-section of the cavity of the feeding channel 22 is a trapezoidal structure, that is, the opening area of the end of the feeding channel 22 facing the isolation cover 21 is smaller than the opening area of the end of the feeding channel 22 facing away from the isolation cover 21.

[0032] In this embodiment, both the air supply component and the dust suction component are connected to the feeding channel 22. The air supply component is used to drive the air in the feeding channel 22 so that the dust suction component can remove dust from the flowing air in the feeding channel 22.

[0033] Specifically, the air supply component includes two air outlet nozzles 23 and a blower. The first side wall and the second side wall of the feeding channel 22 are respectively provided with a first air outlet and a second air outlet. The two air outlet nozzles 23 are respectively connected to the first air outlet and the second air outlet, and the two air outlet nozzles 23 are both connected to the blower through an air supply pipe 24 to provide wind power through the blower. The wind power blows to the front and back sides of the backlight module in the feeding channel 22 through the air supply pipe 24 and the air outlet nozzles 23.

[0034] It should be noted that the air outlet nozzle 23 includes a nozzle body, a main air outlet duct 231 and six side air outlet ducts 232 arranged on the nozzle body. The nozzle body is a cylindrical structure. The bottom area of the nozzle body is larger than the bottom area of the air supply pipe 24. The central axis of the nozzle body is on the same straight line as the central axis of the air supply pipe 24. The opening of the main air outlet duct 231 is adapted to the pipe opening size of the air supply pipe 24. The central axis of the main air outlet duct 231 is on the same straight line as the central axis of the nozzle body. The six side air outlet ducts 232 are distributed at equal angles along the circumference of the nozzle body. One end opening of the side air outlet duct 232 is located on the side wall of the main air outlet duct 231, and the other end opening of the side air outlet duct 232 is located on the bottom surface of the nozzle body.

[0035] It should be noted that, in other embodiments, the air outlet nozzle 23 can be a wind knife, and multiple air outlets of the wind knife are directed toward the backlight module in the feeding channel 22, and the air outlet direction of the wind knife is tilted outward relative to the bottom of the feeding channel 22 to avoid dust from being blown into the isolation cover 21 as much as possible. It can be understood that the wind knife is a prior art, so it will not be explained in detail.

[0036] Specifically, the dust collection component includes two air flow ducts 25 and an exhaust fan. The third side wall and the fourth side wall of the feeding channel 22 are respectively provided with a first exhaust port and a second exhaust port. The two air flow ducts 25 are respectively connected to the first exhaust port and the second exhaust port. Both air flow ducts 25 are connected to the exhaust fan. It should be noted that in order to achieve the effect of the dust collection component to remove dust from the flowing air in the feeding channel 22, a filter component is arranged between the air flow duct 25 and the exhaust fan. That is to say, the air flow duct 25 is connected to the exhaust fan through the filter component, so that the filter component can be used to remove dust from the flowing air from the feeding channel 22 and then discharged through the exhaust fan.

[0037] It should be noted that the third side wall and the fourth side wall are arc surfaces. Specifically, the third side wall and the fourth side wall are recessed in opposite directions to form corresponding arc surfaces.

[0038] In this embodiment, the first side wall and the second side wall are positioned opposite to each other, the third side wall and the fourth side wall are positioned opposite to each other, and the first side wall is located above the backlight module in the feeding channel 22, the second side wall is located below the backlight module in the feeding channel 22, and the third side wall and the fourth side wall are respectively located on two opposite sides of the first side wall.

[0039] In this embodiment, the filtering component includes an installation pipe body 26 and a dust removal filter bag 28 disposed in the installation pipe body 26. One end of the installation pipe body 26 is connected to the air flow pipe 25, and the other end of the installation pipe body 26 is connected to an exhaust fan. Specifically for installing the dust removal filter bag 28, a clamping groove 31 is provided inside the installation pipe body 26, and a clamping head 32 is connected to the dust removal filter bag 28. The clamping head 32 is clamped with the clamping groove 31, so that the dust removal filter bag 28 is detachably connected to the installation pipe body 26, thereby facilitating the replacement of the dust removal filter bag 28.

[0040] It can be understood that when the backlight module enters the conveyor belt 11 from the feeding channel 22, the blower provides wind power, and the wind power is conveyed to the air outlet nozzle 23 through the air supply pipe 24. The main air duct 231 and the side air duct 232 of the air outlet nozzle 23 are used to diffuse and output the wind power, increasing the air blowing area and realizing the air blowing effect on the front and back sides of the backlight module in the feeding channel 22. Then, the exhaust fan extracts the flowing air in the feeding channel 22, and the flowing air passing through the air flow pipe 25 is output after flowing through the dust removal filter bag 28, realizing the dust removal effect on the backlight module. In addition, the bottom surface of the backlight module in the feeding channel 22 is blown by the air outlet nozzle 23, so that the backlight module has a floating effect, which is beneficial for manually pushing the backlight module onto the conveyor belt 11 and reducing the wear on the bottom of the backlight module.

[0041] It should be noted that a movable slot is provided on the installation pipe body 26, and a movable plate 27 is hinged to the installation pipe body 26. The movable plate 27 is used to block the movable slot. When installing the dust removal filter bag 28, the movable plate 27 is opened, and the dust removal filter bag 28 is placed into the installation pipe body 26 from the movable slot.

[0042] In this embodiment, the diameter of the installation pipe body 26 is larger than the diameter of the air flow pipe 25. The opening of the dust removal filter bag 28 is aligned with the pipe orifice position of the air flow pipe 25, and the surface area of the opening of the dust removal filter bag 28 is larger than the surface area of the pipe orifice of the air flow pipe 25.

[0043] In this embodiment, an induction component is provided on the feeding channel 22. The induction component includes an infrared sensor 41 and a microcontroller. The infrared sensor 41 is located at the edge of the inner side wall of the feeding channel 22 far from the isolation cover 21. The infrared sensor is connected to the microcontroller, and the microcontroller is respectively connected to the exhaust fan and the blower through control switches. It can be understood that the infrared sensor 41 is used to sense the backlight module in the feeding channel 22 and to send an induction signal to the microcontroller when it senses that there is a backlight module in the feeding channel 22. The microcontroller is used to turn on the corresponding control switch according to the induction signal to ensure that the air supply component and the dust collection component are in a suspended working state when there is no feeding, which is beneficial for reducing the unnecessary loss of this dust removal mechanism and for reducing industrial energy consumption.

[0044] In specific implementation, an isolation cover 21 is arranged on the workbench 10 to surround the conveyor belt 11. The isolation cover 21 is used to isolate the conveyor belt 11, and a feeding channel 22 is connected to the isolation cover 21. The feeding channel 22 communicates with the isolation cover 21. The air supply component and the dust suction component are respectively connected to the feeding channel 22. When the backlight module enters the conveyor belt 11 from the feeding channel 22, the backlight module is blown with air by the air supply component, so that the dust on the backlight module floats up. Then, the flowing air in the feeding channel 22 is dust-removed by the dust suction component, so as to achieve the dust-removing effect on the backlight module, which is beneficial to improving the yield of the production line.

[0045] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the feeding and conveying device of the present application has only the above-mentioned single implementation process. On the contrary, as long as the feeding and conveying device of the present application can be implemented, it can be included in the feasible implementation solutions of the present application.
