Description

A conveying mechanism for reducing foreign matter adhesion to substrates Technical Field

[0001] This utility model belongs to the field of substrate conveying technology, and specifically relates to a conveying mechanism that reduces the adhesion of foreign matter to substrates. Background Technology

[0002] Currently, during the substrate baking process, the substrate is carried into the UV (ultraviolet) baking machine by a conveyor belt for exposure, and then conveyed out by a conveyor belt to a board collecting machine. The process includes board feeding, board surface cleaning, board placement, conveyor belt feeding, UV baking, conveyor belt output, and board collecting.

[0003] In practical applications, current conveyor belts are prone to causing foreign objects to stick to the substrate, leading to substrate scrapping. The reasons are as follows:

[0004] 1. When cleaning the substrate, personnel use a dust roller to clean the substrate surface and then place the substrate on the feeding equipment. If the personnel are not clean enough, foreign objects are easily dropped onto the conveyor belt. The conveyor belt is in full contact with the substrate surface, and the contact area is large, so foreign objects on the surface of the conveyor belt are easily adhered to the substrate.

[0005] 2. The conveyor belt does not have a real-time cleaning function. It is usually cleaned during the production intervals of each product. If foreign objects on the conveyor belt cannot be removed in time during production, they will stick to the substrate. If personnel find this, the machine needs to be stopped for cleaning, which will affect the equipment's production capacity. Summary of the Invention

[0006] The purpose of this invention is to provide a conveying mechanism that reduces foreign matter adhesion to a substrate, thereby solving the problems mentioned in the background art. The conveying mechanism provided by this invention reduces the contact area between the conveyor belt and the substrate, thus reducing the possibility of foreign matter adhering to the substrate.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a conveying mechanism for reducing foreign matter adhesion to a substrate, comprising a drive shaft, a driven shaft, and a drive motor for driving the drive shaft to move, all mounted on a frame, wherein the drive shaft and the driven shaft are connected by two or three strip conveyor belts.

[0008] To prevent the conveyor belt from shifting and to ensure the stability of the substrate support, the driven shaft is further provided with an annular groove corresponding to the conveyor belt on its circumference.

[0009] To further remove foreign objects from the surface of the conveyor belt, a dust collection box is also included, which is located below the conveyor belt.

[0010] In order to create negative pressure inside the outer casing, foreign objects on the conveyor belt are brought into the interior of the outer casing. Furthermore, the dust collection box includes an outer casing, and the interior of the outer casing is provided with a removable dust collection drawer. The bottom of the dust collection drawer is provided with a filter plate, and a fan is connected to the bottom of the outer casing.

[0011] To further support the dust collection drawer, a support block located below the dust collection drawer is connected to the inner wall of the outer casing.

[0012] To guide foreign objects entering the outer casing and prevent them from accumulating above the dust collection drawer's side panel, a ramp is further connected to the inner wall of the outer casing, located above the dust collection drawer's side panel.

[0013] To ensure effective cleaning of the conveyor belt, a dust guide cover is attached to the top of the outer casing, and a rotatable brush roller is installed in the middle of the top of the dust guide cover.

[0014] To ensure effective cleaning of the conveyor belt, brush strips are further installed on both sides of the brush roller above the dust guide cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses three strip-shaped conveyor belts to transport the substrate, which effectively reduces the contact area between the substrate and the conveyor belt compared to the conveyor belt in the prior art, thereby reducing the possibility of foreign objects adhering to the substrate.

[0017] 2. This utility model removes foreign objects from the surface of the conveyor belt through a dust removal box, further preventing foreign objects from sticking to the substrate.

[0018] 3. A dust guide cover is connected to the top of the outer shell of this utility model. A rotatable brush roller is installed in the middle of the top of the dust guide cover. The brush roller is driven to rotate by the movement of the conveyor belt, thereby brushing off foreign objects on the surface of the conveyor belt and ensuring the cleaning effect of the conveyor belt.

[0019] 4. This utility model also includes two brush strips, which are used to clean foreign objects from the surface of the conveyor belt, further ensuring the cleaning effect. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please refer to Figures 1-5. This utility model provides the following technical solution: a conveying mechanism for reducing foreign matter adhesion to a substrate, including a drive shaft 1 and a driven shaft 3 respectively mounted on a frame via bearings. A drive motor is also mounted on the frame. The output end of the drive motor is connected to the shaft end of the drive shaft 1 via belt drive. The drive shaft 1 and the driven shaft 3 are connected by three strip-shaped conveyor belts 2. The middle conveyor belt 2 is located in the middle position between the drive shaft 1 and the driven shaft 3. The two side conveyor belts 2 are symmetrically arranged on both sides of the middle conveyor belt 2 and are close to the shaft ends of the drive shaft 1 and the driven shaft 3.

[0029] By adopting the above technical solution, this utility model uses three strip-shaped conveyor belts 2 to transport the substrate. Compared with the conveyor belt in the prior art, it effectively reduces the contact area between the substrate and the conveyor belt 2, thereby reducing the possibility of foreign objects adhering to the substrate.

[0030] Specifically, the driven shaft 3 has an annular groove 31 on its circumference corresponding to the conveyor belt 2, and the groove depth of the annular groove 31 is less than the thickness of the conveyor belt 2.

[0031] By adopting the above technical solution, the position of the conveyor belt 2 is limited by the annular groove 31, so as to avoid the conveyor belt 2 from shifting and ensure the stability of the substrate support.

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is that, specifically, it also includes a dust removal box 4, which is located below the conveyor belt 2 and at the end of the conveyor belt 2 that is close to the feeding end, so that the cleaned conveyor belt 2 can be directly used to transport the substrate, reducing the possibility of secondary pollution.

[0034] By adopting the above technical solution, foreign objects on the surface of the conveyor belt 2 are removed by the dust removal box 4, further preventing foreign objects on the conveyor belt 2 from sticking to the substrate.

[0035] Specifically, the dust collection box 4 includes an outer shell 47, inside which is a removable dust collection drawer 44. The bottom of the dust collection drawer 44 is provided with a through groove, and a step is provided between the through groove and the side wall of the dust collection drawer 44. A filter plate 48 is placed on the step. The filter plate 48 is made of non-woven fabric, and the four sides of the filter plate 48 are attached to the side wall of the dust collection drawer 44. An air guide hood 46 is connected to the bottom of the outer shell 47, and a fan 45 is connected to the bottom end of the air guide hood 46.

[0036] By adopting the above technical solution, the fan 45 draws air to create negative pressure inside the outer casing 47. Air enters the interior from the top of the outer casing 47, thereby bringing in foreign objects from the conveyor belt 2. These foreign objects are then filtered by the filter plate 48 and remain in the dust collection drawer 44. In addition, the interior of the dust collection drawer 44 and the filter plate need to be cleaned or the filter plate 48 needs to be replaced according to the production progress.

[0037] Specifically, a support block 49 located below the dust collection drawer 44 is connected to the inner wall of the outer casing 47.

[0038] The above technical solution is used to support the dust collection drawer 44.

[0039] Example 3

[0040] The difference between this embodiment and embodiment 2 is that, specifically, an inclined block 410 located above the dust collection drawer 44 is connected to the inner wall of the outer shell 47.

[0041] By adopting the above technical solution, the inclined block 410 guides foreign objects entering the interior of the outer casing 47, preventing them from accumulating above the panel of the dust collection drawer 44.

[0042] Example 4

[0043] The difference between this embodiment and embodiment 2 is that, specifically, a dust guide cover 41 is connected to the top of the outer shell 47, and a rotatable brush roller 42 is installed at the middle position above the dust guide cover 41, with the brush roller 42 in contact with the surface of the conveyor belt 2.

[0044] By adopting the above technical solution, the movement of the conveyor belt 2 drives the brush roller 42 to rotate, thereby brushing off foreign objects on the surface of the conveyor belt 2 and ensuring the cleaning effect of the conveyor belt 2.

[0045] Specifically, brush strips 43 are installed on both sides of the brush roller 42 above the dust guide cover 41.

[0046] By adopting the above technical solution, two brush strips 43 are used to clean foreign objects on the surface of the conveyor belt 2, further ensuring the cleaning effect.

[0047] In summary, this invention uses three strip-shaped conveyor belts 2 to transport the substrate, which effectively reduces the contact area between the substrate and the conveyor belts 2 compared to the conveyor mesh belts in the prior art, thereby reducing the possibility of foreign objects adhering to the substrate. This invention also uses a dust collector 4 to remove foreign objects from the surface of the conveyor belts 2, further preventing foreign objects from adhering to the substrate. A dust guide hood 41 is connected to the top of the outer casing 47 of this invention, and a rotatable brush roller 42 is installed in the middle of the top of the dust guide hood 41. The movement of the conveyor belts 2 drives the brush roller 42 to rotate, thereby brushing off foreign objects from the surface of the conveyor belts 2, ensuring a cleanliness of the conveyor belts 2. This invention also includes two brush strips 43, which clean foreign objects from the surface of the conveyor belts 2 separately, further ensuring a cleanliness level.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
