Description

Technical Field

[0001] This utility model relates to the field of steel mesh cleaning technology, and in particular to a steel mesh cleaning device. Background Technology

[0002] In the existing technology, SMT stencils play a crucial role in chip manufacturing. They are an important tool to ensure soldering quality and production efficiency. Functionally, they can precisely control solder paste deposition. Through the perforation pattern on the SMT stencil, the solder paste is ensured to be accurately printed onto the soldering positions on the PCB. By changing the size and shape of the perforations on the stencil, the amount of solder paste used can be controlled, thereby ensuring soldering quality. The stencil needs to be cleaned after use to facilitate subsequent reuse.

[0003] A search revealed a Chinese patent application with patent number 201921031309.1, which discloses an SMT stencil cleaning device, including a cleaning tank. The top of the cleaning tank is connected to a lid via a hinge. A support plate is installed inside the cleaning tank. An ultrasonic generator is installed at the bottom of the cleaning tank's inner cavity. A drain pipe is connected to the support plate.

[0004] The steel mesh cleaning equipment in the aforementioned patent has the following drawbacks: after cleaning, cleaning liquid remains on the surface of the steel mesh, making it impossible to dry the steel mesh quickly, thus making it inconvenient to store it. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] A steel mesh cleaning device, such as Figures 1 to 6 As shown, the ultrasonic cleaning box 1 includes an ultrasonic cleaning chamber 1. Electric telescopic rods 9 are bolted to both sides of the bottom of the ultrasonic cleaning chamber 1. An installation plate 4 is fixed to the output end of the electric telescopic rods 9 via pins. A flap 2 is hinged to one end of the installation plate 4. A connecting pipe 18 is rotatably connected to a through hole on the surface of the installation plate 4. A blower assembly is connected to the top of the connecting pipe 18. A pad 23 is welded to the outer wall of the connecting pipe 18. A placement assembly for placing a steel mesh is fixed to the outer wall of the pad 23. A drying pipe 22 is welded to the bottom of the connecting pipe 18. An air hole 24 is opened on the outer wall of the drying pipe 22. A shielding rod 15 is rotatably connected to the inner wall of the bottom of the ultrasonic cleaning chamber 1. The shielding rod 15 and the drying pipe 22 are slidably connected.

[0029] When the steel mesh needs to be cleaned, the electric telescopic rod 9 is used to drive the flip plate 2 and the mounting plate 4 to move upward. The steel mesh is then placed using the placement assembly. After the steel mesh is placed, the electric telescopic rod 9 drives the mounting plate 4 to move in the opposite direction and enter the ultrasonic cleaning chamber 1. A certain amount of cleaning fluid is injected into the ultrasonic cleaning chamber 1, and then the ultrasonic cleaning chamber 1 is used to perform ultrasonic cleaning on the steel mesh. The ultrasonic cleaning chamber 1 is equipped with an ultrasonic generator and an ultrasonic transducer. Ultrasonic cleaning is an existing technology and will not be described in detail here. After the ultrasonic cleaning of the steel mesh is completed, the electric telescopic rod 9 is used to drive the mounting plate 4 to move upward again, and the steel mesh is removed from the cleaning fluid in the ultrasonic cleaning chamber 1. During this process, the drying tube 22 slides along the shielding rod 15, so that the air holes 24 on the outer wall of the drying tube 22 are exposed to the external environment. The blower assembly can blow air into the drying tube 22, and the air force is discharged through the air holes 24 to dry the steel mesh in the placement assembly.

[0030] By setting the drying tube 22 and the shielding rod 15 to be sliding, the shielding rod 15 will cover the drying tube 22 when the steel mesh is being cleaned, preventing the cleaning fluid from entering the air hole 24.

[0031] The placement assembly includes a placement frame 19 and a baffle 20. The placement frame 19 is fixed to the outer wall of the pad 23 by bolts, and the baffle 20 is welded between the inner walls on both sides of the placement frame 19. A rectangular hole 21 is provided at one end of the placement frame 19.

[0032] The placement frame 19 allows for the placement of steel mesh of different specifications. The top of the placement frame 19 has an opening, and the baffle 20 provides lateral support for the steel mesh. The rectangular hole 21 allows the wind force to act better on the surface of the steel mesh when it is dry.

[0033] The top outer wall of the mounting plate 4 is fixed with a drive motor 3 by bolts, and the output end of the drive motor 3 is fixed with a gear 16 by a pin, and the outer circumference of the connecting pipe 18 is fixed with a gear 17 that meshes with the gear 16 by a pin.

[0034] When the steel mesh is long and needs to be placed, the flap 2 is unfolded along the mounting plate 4, and the drive motor 3 drives multiple placement components to move sequentially to the bottom of the flap 2, so that the steel mesh can be placed in the placement components.

[0035] The blower assembly includes a fixed plate 13 and a hot air blower 14. The fixed plate 13 is welded to the top outer wall of the mounting plate 4, and the hot air blower 14 is fixed to one side outer wall of the fixed plate 13 by bolts. The blower assembly also includes a rotary joint 5 and a bracket 12. The bracket 12 is welded to the top of the mounting plate 4, and the rotary joint 5 is rotatably connected to the inner wall of the through hole opened on the surface of the bracket 12. The rotary joint 5 and the connecting pipe 18 are rotatably connected. The top of the rotary joint 5 and the output end of the hot air blower 14 are connected by a duct 6.

[0036] Hot air is blown into the air duct 6 by the hot air blower 14 and then enters the drying tube 22 through the connecting pipe 18. Finally, the air acts on the surface of the steel mesh through the air hole 24 to dry the steel mesh.

[0037] The bottom of the ultrasonic cleaning box 1 is fixed with valve 2 11 by bolts, and valve 1 8 is fixed with bolts on the side wall of the ultrasonic cleaning box 1. A bent pipe 10 is fixed at the end of valve 1 8 away from the ultrasonic cleaning box 1, and a tapered pipe 7 is welded to the top of the bent pipe 10.

[0038] When valve 1 is opened, the conical tube 7 and the bent tube 10 facilitate the injection of cleaning fluid into the ultrasonic cleaning chamber 1. After cleaning, valve 2 is opened to facilitate the discharge of the waste liquid after cleaning.

[0039] Working principle: When cleaning the stencil used in SMT production is required, the flip plate 2 is first rotated and opened along the mounting plate 4. Then, the stencil to be cleaned is placed in the placement frame 19. The drive motor 3 drives the pad 23 to rotate so that when multiple stencils need to be cleaned at once, multiple placement frames 19 rotate sequentially to the bottom of the flip plate 2 for easy placement of the stencils. After placement, a certain amount of cleaning fluid is injected into the ultrasonic cleaning box 1 through the valve 8, the bend 10, and the tapered pipe 7. The flip plate 2 is then closed again, and the ultrasonic cleaning box 1, together with the cleaning fluid, performs ultrasonic cleaning on the stencil. After cleaning, the electric telescopic rod 9 drives the mounting plate 4 and the flip plate 2 to move upward, and the stencil gradually extends out of the cleaning fluid. Then, the hot air blower 14 is started, and hot air is blown into the air duct 6. The hot air is finally discharged through the air hole 24 to dry the stencil in the placement frame 19.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
