Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically a self-cleaning mesh belt circulating conveyor drying equipment. Background Technology

[0002] Currently, the conveying mechanisms in drying equipment for products such as solar cell silicon wafers mainly consist of roller conveyors and traditional mesh belt conveyors. During the drying process, adhesive substances often adhere to the surface of the rollers or mesh belts, causing secondary adhesion and contamination of subsequently conveyed products, thus affecting product quality. Existing conventional methods include reducing the contact area between the conveying mechanism and the product to reduce the adhesion area, which is only a temporary solution; or periodic manual cleaning, which is labor-intensive and affects the efficiency of the production line drying operation. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a self-cleaning mesh belt circulating conveying and drying equipment, including a tank body. The tank body is divided into upper and lower parts by a horizontally arranged partition. A drying box is horizontally arranged on the upper side of the partition, and the drying box has a feeding end and a discharging end. A water washing tank, an acid / alkali washing tank, a water washing tank, and a drying tank are arranged horizontally in sequence on the lower side of the tank body. The water washing tank corresponds to the discharging end of the drying box, and the drying tank corresponds to the feeding end of the drying box.

[0004] It also includes a mesh belt circulation conveyor mechanism, which includes a mesh belt connected at the end and a drive component for driving the mesh belt to circulate and convey. The mesh belt passes through the drying box, water washing tank one, acid / alkali washing tank, water washing tank two and drying tank in sequence to form a circulation conveyor.

[0005] The drive assembly includes a servo motor, a drive wheel driven by the servo motor to circulate the conveyor belt, and a driven wheel driven by the conveyor belt.

[0006] Furthermore, the drive assembly also includes a tension adjustment mechanism corresponding to the driven wheel.

[0007] Wherein: a water washing nozzle corresponding to the mesh belt is provided above the first water washing tank; an acid / alkali washing nozzle corresponding to the mesh belt is provided above the acid / alkali washing tank; a water washing nozzle corresponding to the mesh belt is provided above the second water washing tank; and an air knife corresponding to the mesh belt is provided in the drying tank.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The innovative use of a mesh belt circulation transmission method cleans the non-product transport section of the mesh belt while the drying operation is underway, removing the adhesive residue generated during the production process that adheres to the mesh belt. This not only does not affect the normal drying production operation, but also cleans the adhesive residue on the mesh belt in a timely manner, thereby reducing the impact of the adhesive residue on the product and avoiding secondary contamination.

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0013] Example 1:

[0014] Please see Figure 1 The self-cleaning mesh belt circulating conveyor drying equipment provided in this embodiment 1 includes a tank 10. The tank 10 is divided into upper and lower parts by a horizontally arranged partition 11. A drying box 20 is horizontally arranged on the upper side of the partition 11, and the drying box 20 has a feeding end 21 and a discharging end 22. A water washing tank 40, an acid / alkali washing tank 50, a water washing tank 60, and a drying tank 70 are arranged horizontally in sequence on the lower side of the tank 10. A water washing nozzle 1 corresponding to the mesh belt 34 is arranged above the water washing tank 40. An acid / alkali nozzle corresponding to the mesh belt 34 is arranged above the acid / alkali washing tank 50. A water washing nozzle 2 corresponding to the mesh belt 34 is arranged above the water washing tank 60. An air knife corresponding to the mesh belt 34 is arranged in the drying tank 70. The water washing tank 40 corresponds to the discharging end 22 of the drying box 20, and the drying tank 70 corresponds to the feeding end 21 of the drying box 20.

[0015] It also includes a mesh belt circulation conveyor mechanism, which includes a mesh belt 34 connected at the end and a drive component for driving the mesh belt 34 to circulate and convey. The mesh belt 34 passes through the drying box 20, the first water washing tank 40, the acid / alkali washing tank 50, the second water washing tank 60 and the drying tank 70 in sequence to form a circulation conveyor.

[0016] The drive assembly includes a servo motor 31, a drive wheel 32 driven by the servo motor 31 and the mesh belt 34 for cyclic conveying, a driven wheel 33 driven by the mesh belt 34, and a tension adjustment mechanism 35 corresponding to the driven wheel 33.

[0017] The working principle of this utility model:

[0018] The innovative use of a mesh belt circulating conveyor mechanism first drives the drive wheel 32 via a servo motor 31, which in turn drives the mesh belt 34 to circulate and convey products. The driven wheel 33 driven by the mesh belt 34 (the position of the driven wheel 33 can be adjusted by the tension adjustment mechanism 35, thereby adjusting the tension of the mesh belt 34 and ensuring that the mesh belt 34 is in a horizontal tensioned state) circulates through the drying chamber 20 to dry the products. After that, the mesh belt 34 circulates to the lower layer and passes through the first water washing tank 40 to cool the mesh belt 34. Then it passes through the acid / alkali washing tank 50 (the acid or alkali washing is determined according to the type of adhesive) to remove the adhesive adhering to the mesh belt 34. Then it passes through the second water washing tank 60 to remove the residual acid / alkali solution from the mesh belt 34. Finally, it passes through the drying tank 70 to remove the residual water droplets from the mesh belt 34. After cleaning, the mesh belt 34 circulates back to the feed end 21 of the drying chamber 20, and the product is circulated and conveyed to complete the drying operation.

[0019] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
