Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of gasoline filter assembly, in particular to a gasoline filter assembly machine and a using method thereof. BACKGROUND

[0002] The gasoline filter is a key filtering device in the automobile fuel system, mainly used for filtering impurities (such as rust, dust, gum, moisture, etc.) in gasoline, preventing these impurities from entering precision components such as fuel pumps and fuel injectors, avoiding component wear, blockage or failure, thereby protecting the normal operation of the engine, and improving the fuel combustion efficiency and stability. Its structure mainly includes an end cover, an outer shell, a filter element and a sealing structure.

[0003] In the process of assembling the gasoline filter, the filter material is pretreated first, the cut paper filter material is folded into a corrugated shape (the number and density of the folds are determined according to the design), to ensure that the folds are uniform, without overlapping, and the edges are aligned, to avoid uneven stress during subsequent bonding. The bonding area of the end cover is glued by a mechanical arm, then the folded filter material is placed vertically into the bonding area of the end cover, to ensure that the filter material edge completely covers the glued surface of the end cover (without deviation), and the filter material folds are perpendicular to the end cover plane (to avoid local stress caused by inclination). Then, the end cover and the outer shell are assembled, which can be tightened by a buckle or tightened according to the specified torque.

[0004] In the current mainstream assembly process, the end cover bonding area needs to be coated with glue in a circular or annular design (the coating area is larger than the actual contact surface), to ensure complete coverage and bonding with the paper filter material end face in a wave structure. However, this process has obvious defects. First, the glue cost is relatively high, and the actual utilization rate of the glue is low, most of the glue will not contact the lower edge of the filter material. In addition, if the amount of glue is not properly controlled or the pressure is uneven, excess glue is easy to overflow from the gap between the end cover and the filter material and penetrate to the surface of the filter material folds. Since the paper filter material has fine and dense pores, the glue will directly block the filter holes, resulting in a reduction in the effective filtration area. If the filter material is coated with glue first, the metal filter material can adapt to this process, but the paper filter material has a ring-shaped wave structure and low material strength. During the glue coating process, the folds are easy to deform or deviate due to external forces, causing adjacent folds to stick together, ultimately leading to functional failure of the filter material, significantly increasing material loss and scrap rate.

A suction port (431) and an annular negative pressure groove (432) are provided on the upper and lower sides of the suction cup (43), respectively. The suction port (431) and the annular negative pressure groove (432) are connected.

10. A method of using a gasoline filter cartridge assembly machine, using the gasoline filter cartridge assembly machine according to any one of claims 1 to 9, characterized in that, The method of use specifically includes the following steps: S1 Pretreatment preparation: Inspect the corrugated annular paper filter material (5) and end cap (6) to ensure that the paper filter material (5) has uniform folds, no overlap, and aligned edges, and that the end cap (6) is undamaged. Then, place the paper filter material (5) onto the cylinder (21) and use negative pressure to place the end cap (6) under the suction cup (43). S2 Positioning Process: Turn on the first motor (26), the first motor (26) drives the first lead screw (261) to rotate, and the first nut seat (262) on the first lead screw (261) drives the push block (25) to move upward. The inclined part on the push block (25) will first contact the inclined part of the wedge-shaped part (241) at the same height at the bottom in each set of limit plates (24), and push the corresponding limit plate (24) out from the placement port (211) along the radius of the cross section of the cylinder (21). At the same time, the spring pins (243) on the upper and lower sides of the limit plate (24) are compressed until the vertical surface of the push block (25) abuts against the vertical part of the wedge-shaped part (241). At this time, the front edge of the limit plate (24) abuts against the crease of the paper filter material (5) and is limited. Depending on the number of creases in the paper filter material (5), it can be selected whether to continue to move the push block (25) upward to increase the number of push limit plates (24). S3 glue processing: after the limit, the first cylinder (28) pushes the lifting support (29) to move along the direction of the chute (27) until the upper edge of the paper filter (5) moves below the glue brush (35), then start the electric push rod (33) and the second motor (31), the second motor (31) drives the glue brush (35) to make circular motion, the electric push rod (33) makes the glue brush (35) make wave motion while making circular motion, to brush glue on the upper edge of the paper filter (5), after brushing glue, the third motor (38) drives the second screw (381) to rotate, then under the action of the second nut seat (382), the connecting frame (39) drives the glue brush (35) to leave the upper of the paper filter (5); S4 assembly combination: after brushing glue, the first cylinder (28) continues to push the paper filter (5) to move upward, while the second cylinder (42) drives the end cover (6) to move downward through the suction cup (43), so that the end cover (6) is pressed on the upper edge of the paper filter (5), and then the negative pressure is disconnected, so that the suction cup (43) and the end cover (6) are separated, then the worker can take out the paper filter (5) and the end cover (6) together.
