Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment, and in particular to a pipeline filtration device for wet process processing equipment. Background Technology

[0002] Wet circuit board processes generally refer to processes completed in a chemical solution environment, including chemical copper plating, etching, copper electroplating, chemical nickel-gold plating, chemical silver plating, chemical nickel-gold plating, OSP surface anti-oxidation film, etc. Because it is necessary to provide processing conditions for circulating chemical solutions, pipelines are required to transport the solutions. The solutions must not contain impurities, otherwise they will have an adverse effect on the wet process.

[0003] During the delivery of medicine, it is first necessary to prevent the presence of large particulate impurities, such as debris and filaments. Large impurities can easily reduce the service life of the filter element used in medicine filtration and may decompose, affecting the effectiveness of the active components of the medicine.

[0004] Currently, stainless steel mesh, plastic mesh, or lint-free cloth with a certain mesh size are generally installed at the connection points of pipelines to block larger impurities. However, simple sheet-like stainless steel mesh, plastic mesh, or lint-free cloth can affect the flow rate of the chemical solution per unit time, making it difficult to accurately control the flow rate per unit time. In addition, the frequency of disassembly and maintenance is relatively high, which affects processing efficiency.

[0005] Therefore, there is a need for a filtration device that can meet the filtration requirements of larger impurities in the equipment pipelines of wet process without affecting the accuracy of chemical flow control per unit time and processing efficiency. Utility Model Content

[0006] This utility model aims to solve the problem that existing stainless steel mesh, plastic mesh, or lint-free cloth filters installed in the pipelines of wet process equipment can easily obstruct the flow of chemicals, affecting the flow rate of chemicals per unit time and thus impacting processing efficiency. The invention provides a filter device for wet process equipment pipelines, comprising a protruding end and a base end that are interconnected. The upper end of the base end is a top surface, and the lower end is a bottom surface, with the area of ​​the top surface being smaller than that of the bottom surface. The protruding end extends from the top surface in a direction away from the bottom surface. The side of the protruding end that intersects with the base end is an open through surface, while the other sides are closed filter surfaces. Several through grooves are distributed on the filter surface.

[0007] Optionally, the base end has a frustum-shaped structure.

[0008] Optionally, the protruding end has a cylindrical structure.

[0009] Optionally, the bottom end is circular and the top end is quadrilateral.

[0010] Optionally, the protruding end is a quadrilateral prism structure.

[0011] Optionally, the through slot is a circular hole or a square hole.

[0012] Optionally, a plurality of the through grooves are evenly distributed on the filter surface.

[0013] Optionally, a fixing seat is provided at the bottom end, and the fixing seat is a cylindrical body extending outward from the bottom end.

[0014] Optionally, the fixing base is provided with a buckle, which is a protrusion structure provided from the surface of the edge area of ​​the fixing base toward the protruding end.

[0015] Optionally, the end surface of the base is provided with several through grooves.

[0016] Furthermore, the material of the filter device is PP, PVC, PE, PET, PC, PS, PTFE or ABS.

[0017] Furthermore, the cross-section of the base end is trapezoidal.

[0018] The filtration device of this utility model has a base end that can be installed to match the diameter of the pipe opening. It also has a raised end and a through groove, forming an internal through-type structure that allows the medicine to flow from the base end to the raised end. Because the overall area of ​​the filter surface of the raised end is large, the flow rate of the medicine per unit time is large and smooth, effectively preventing the problem of difficulty in precise control. In addition, the large overall area of ​​the filter surface can extend the service life, reduce the maintenance frequency, and improve the processing efficiency. Attached Figure Description

[0030] The wet process equipment pipeline filtration device 10 provided by this utility model includes a protruding end 110 and a base end 120 that are interconnected; the upper end of the base end 120 is a top surface end 1210, and the lower end of the base end 120 is a bottom surface end 1220, and the area of ​​the top surface end 1210 is smaller than the area of ​​the bottom surface end 1220; the protruding end 110 extends from the top surface end 1210 in a direction away from the bottom surface end 1220; the side of the protruding end 110 that is interconnected with the base end 120 is an open through surface, and the other sides are closed filter surfaces 1110; a plurality of through grooves 1120 are distributed on the filter surface 1110.

[0031] The bottom end 1220 of the base end 120 is larger than the top end 1210, so that the base end 120 is fixedly installed on the pipe from the bottom end 1220, forming a firm installation structure to prevent the filter device 10 from loosening or falling off during use. The protruding end 110 extends from the top end 1210 to form a filter surface 1110, and a through groove 1120 is provided to effectively increase the filter area, making the flow rate of the medicine more controllable and smoother per unit time. In addition, the horizontal cross-sectional dimension of the protruding end 110 is smaller than the size of the pipe, forming a certain gap distance between them, increasing the space for the medicine to pass through the filter device 10, and further reducing the obstruction of the medicine by the filter device 10.

[0038] In one embodiment, the protruding end 110 is a quadrilateral prism structure.

[0039] Since the bottom end 1220 needs to be fixedly installed with the pipe, and the pipe is generally cylindrical, the bottom end 1220 is set to be circular to effectively fix it to the pipe. The top end 1210 is quadrilateral, and the protruding end 110 is a quadrilateral column structure, which can form a filter surface 1110 with sharp edges, which has stronger anti-deformation performance against the impact of the medicine during application.

[0040] In one embodiment, the through groove 1120 is a circular or square hole, or it can be a geometric shape such as a triangle, rhombus, mesh structure, or honeycomb structure.

[0046] The buckle 1310 is provided to cooperate with the connection point of the pipe, so as to form a more tight structural fixation for the filter device 10, and to effectively lock the filter device 10 in all directions. The height of the protrusion structure of the buckle 1310 is generally 3mm to 10mm, preferably 5mm.

[0047] In one embodiment, the surface of the base end 120 is provided with a plurality of through grooves.

[0048] Without compromising the stability of the fixed installation, a through groove can also be provided at the base end 120 to facilitate the smoother passage of the medicine through the filter device 10.

[0049] Optionally, the filter device 10 may be made of PP, PVC, PE, PET, PC, PS, PTFE or ABS.

[0050] Optionally, the cross-section of the base end 120 is trapezoidal.
