Description

Technical Field

[0001] This utility model belongs to the field of automotive rubber strip processing technology, specifically a wiping and drying mechanism for applying adhesive to automotive rubber strips. Background Technology

[0002] Automotive rubber strips are rubber or synthetic material sealants installed in the gaps of the car body, mainly serving to seal, absorb shocks, and provide protection. The adhesive backing is the bonding layer used to fix the rubber strip, ensuring that it is firmly attached to the designated location on the car body. It must have strong adhesion, temperature resistance, and anti-aging properties to ensure a long-lasting bond between the rubber strip and the car body.

[0003] Currently, the application of adhesive to automotive rubber strips is typically done manually. Manual application not only suffers from uneven application and significant adhesive waste, but also often fails to allow for timely drying, resulting in the adhesive layer on the strip not fully curing and affecting subsequent bonding processes. Specifically, if the adhesive is not dried promptly, it is easily contaminated with dust or accidentally touched, causing uneven surfaces or reduced bond strength. Furthermore, wet adhesive strips are prone to displacement or deformation during handling or covering substrates, ultimately affecting the sealing effect and product appearance.

[0004] Therefore, there is an urgent need for an automated mechanism that can integrate gluing, wiping and drying to solve problems such as uneven gluing, glue waste and poor bonding caused by untimely drying in existing manual operations. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a wiping and drying mechanism for applying adhesive to automotive rubber strips, thereby solving the problems mentioned in the background art, such as inaccurate manual application, waste of adhesive, incomplete application, and poor adhesion caused by untimely drying.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a wiping and drying mechanism for applying adhesive to automotive adhesive strips, including a horizontal rail, a cylinder sliding plate, a drying component, an adhesive bottle, a cylinder, a dispensing component, a wiping component, and a connecting component; the cylinder sliding plate is slidably mounted on the horizontal rail; the drying component is provided on the cylinder sliding plate; the adhesive bottle is fixedly connected to the cylinder sliding plate; the cylinder is fixedly connected to the cylinder sliding plate through a first fixing block; the dispensing component is provided inside the cylinder; a first one-way valve is installed at the bottom end of the cylinder, and a wiping component is provided at the bottom end of the first one-way valve; a second one-way valve and a discharge valve are installed on the side wall of the cylinder; the second one-way valve is interconnected with the adhesive bottle through the connecting component. This mechanism, by integrating adhesive application and drying functions, systematically improves the automation level and processing effect of the operation. Specifically, the dispensing component uses a conventional micro servo motor to drive a lead screw nut, controlling the sealed sliding of the cylinder sliding plate inside the cylinder, thereby controlling the amount of adhesive output, which helps to reduce adhesive waste and ensure the accuracy of dosage. The uniform wiping function is performed by a wiping component. The adhesive enters a wiping tube with a square opening at the bottom through a first one-way valve, and then wets squarely distributed wiping brushes. This structural design allows the wiping brushes to fully cover the adhesive strip surface, ensuring even and complete adhesive application, overcoming the shortcomings of incomplete manual application. The instant drying function is provided by a drying component. After the wiping action is completed, a hot air blower located on the side wall of the cylinder sliding plate blows hot air onto the adhesive strip surface through an air duct, allowing the adhesive layer to quickly and initially cure. This process effectively prevents the adhesive from being contaminated or shifting while still wet, ensuring the reliability and bonding strength of subsequent bonding processes. Through the integration and continuous operation of the above functions, this mechanism achieves efficient, precise, and automated operation of adhesive application and drying for automotive adhesive strips.

[0007] Preferably, the drying component includes a hot air blower and an air duct; the hot air blower is fixedly connected to the side wall of the cylinder sliding plate, and the bottom end of the hot air blower is provided with an air duct.

[0008] Preferably, the connector includes a first hose; the second one-way valve is connected to the glue bottle directly below it via the first hose; during operation, the first hose connects the second one-way valve and the glue bottle to facilitate liquid inlet operation.

[0009] Preferably, the wiping component includes a wiping tube and a wiping brush; the bottom end of the first one-way valve is connected to the wiping tube; a set of wiping brushes is fixedly connected to the bottom opening of the wiping tube, and the ends of the wiping brushes block the bottom opening of the wiping tube; the bottom opening of the wiping tube is squarely distributed.

[0010] Preferably, the liquid lowering component includes a miniature servo motor; the miniature servo motor is fixedly connected to the top of the cylinder; the output end of the miniature servo motor is provided with a lead screw, and the lead screw extends into the cylinder; a sliding disk is slidably connected to the inner wall of the cylinder; the sliding disk is connected to the lead screw through a lead screw nut pair; the bottom end of the sliding disk is fixed to the sliding disk through an annular plate.

[0011] Preferably, a pair of symmetrically distributed guide posts are fixed to the top of the slide plate, and the top of the guide posts penetrates the cylinder; a set of air vents are opened on the outer side wall of the cylinder near the top.

[0013] Preferably, a first threaded rod is threadedly connected to the horizontal plate at the top of the Z-shaped plate, and the bottom end of the first threaded rod is rotatably connected to the top of the fixed plate.

[0014] The advantages of this utility model, which differ from existing technologies, are as follows:

[0015] This invention integrates adhesive application and drying functions, achieving continuous automated operation for processing automotive adhesive strips. The adhesive output is controlled by the liquid dispensing component, uniform coating is achieved via the wiping component, and immediate air drying is provided by the drying component. This effectively solves the problems of inaccurate and incomplete adhesive application, adhesive waste, and poor adhesion caused by untimely drying, which are inherent in existing manual operations, significantly improving processing efficiency and quality.

[0016] The present invention discloses a wiping and drying mechanism for applying adhesive to automotive rubber strips. The bottom end of the wiping tube features a square opening, and the wiping brushes are arranged in a square pattern. This structure allows the wiping brushes to better cover the entire surface of the rubber strip, ensuring uniform and comprehensive adhesive application and overcoming potential omissions or unevenness that may occur with manual wiping.

[0017] This invention features a pair of Z-shaped plates symmetrically distributed about the wiping tube, with the horizontal plate at the bottom contacting both sides of the wiping brush. This structure provides effective lateral support for the wiping brush, preventing bending or deformation during prolonged wiping operations, thus extending its lifespan and ensuring consistently stable wiping results. Furthermore, the height of the Z-shaped plates can be adjusted by rotating the first threaded rod, allowing the support structure to accommodate wiping brushes of different lengths, enhancing the mechanism's versatility and practicality.

[0034] like Figures 1 to 5 As shown, this utility model discloses a wiping and drying mechanism for applying adhesive to automotive rubber strips, comprising a horizontal rail 1; a cylinder sliding plate 11 is mounted on the horizontal rail 1; a drying component is provided on the cylinder sliding plate; an adhesive bottle 12 is fixedly connected to the cylinder sliding plate 11; a cylinder 15 is fixedly connected to the cylinder sliding plate 11 via a first fixing block 14; a liquid discharge component is provided inside the cylinder 15; a first one-way valve 17 is installed at the bottom end of the cylinder 15, and a wiping component is provided at the bottom end of the first one-way valve 17; a second one-way valve 18 and a discharge valve 16 are installed on the side wall of the cylinder 15; the second one-way valve 18 is interconnected with the adhesive bottle 12 via a connector; in the present technology, when applying adhesive to automotive rubber strips... When applying adhesive, a layer of adhesive needs to be applied to the surface, usually done manually. However, manual operation is inaccurate, resulting in wasted adhesive and incomplete application. Therefore, in this invention, the cylinder sliding plate 11 is driven by a cylinder (this is not described in detail in the prior art). The cylinder sliding plate 11 slides on the horizontal rail 1 and can be pushed by a track chain or other device (this is also not described in the prior art). The adhesive is wiped off the surface of the adhesive strip by a wiping component, and then the adhesive is dispensed in precise quantities by a dispensing component, reducing the inaccuracies of manual operation.

[0035] The drying components include a hot air blower 2 and an air duct 21. The hot air blower 2 is fixed to the side wall of the cylinder sliding plate 11, and the air duct 21 is located at the bottom of the hot air blower 2. During operation, the hot air blower 2 is existing technology, and its internal structure will not be described. After wiping the adhesive strip with the wiping component, the air duct 21 blows drying air to perform preliminary drying treatment on the wiped adhesive strip, which facilitates the subsequent application of adhesive strips to the substrate. It is recommended that the outlet air temperature of the hot air blower 2 be controlled between 50℃ and 70℃, which can accelerate the curing of the adhesive without damaging the material of the adhesive strip.

[0036] The connector includes a first hose 22; a second one-way valve 18 is connected to the glue bottle 12 directly below the first hose 22; during operation, the first hose 22 connects the second one-way valve 18 and the glue bottle 12 to facilitate liquid injection.

[0037] The wiping component includes a wiping tube 3 and a wiping brush 31; the bottom end of the first one-way valve 17 is connected to the wiping tube 3; a set of wiping brushes 31 are fixedly connected to the bottom opening of the wiping tube 3, and the ends of the wiping brushes 31 block the bottom opening of the wiping tube 3; the bottom openings of the wiping tube 3 are squarely distributed; during operation, the glue enters the wiping tube 3 through the first one-way valve 17, and then is immersed in the wiping brushes 31. When the wiping brushes 31 wipe the adhesive strip, they wipe the glue onto the surface of the adhesive strip to complete the wiping operation. Since the bottom end of the wiping tube 3 is square, the wiping brushes 31 are also square, which facilitates the wiping operation of the entire adhesive strip.

[0038] The liquid-discharging component includes a miniature servo motor 32; the miniature servo motor 32 is fixedly connected to the top of the cylinder 15; the output end of the miniature servo motor 32 is provided with a lead screw 38, and the lead screw 38 extends into the cylinder 15; a sliding disk 33 is slidably connected to the inner wall of the cylinder 15; the lead screw 38 is connected to the sliding disk 34 through a lead screw nut pair; the bottom end of the sliding disk 34 is fixed to the sliding disk 33 through an annular plate 35. The miniature servo motor 32 can be a closed-loop stepper motor or servo motor with a rated torque of not less than 0.5 N·m and an accuracy of not less than 0.01 mm to ensure precise control of the liquid discharging volume.

[0039] A pair of symmetrically distributed guide posts 36 are fixed to the top of the sliding plate 34, and the tops of the guide posts 36 penetrate the cylinder 15. Their function is to prevent the sliding plate 34 and the sliding disk 33 from rotating under the drive of the lead screw 38, ensuring that they can only move smoothly up and down along the axial direction, further improving the control accuracy and reliability of the liquid flow. A set of vent holes 37 are opened on the outer wall of the cylinder 15 near the top. When the sliding disk 33 moves up and down inside the cylinder 15, the vent holes 37 at the top of the cylinder 15 are used to balance the air pressure, ensuring that the sliding disk 33 can slide smoothly and avoid the formation of air resistance or vacuum, which would affect the liquid flow accuracy. An electric heating wire (not shown in the figure) can be embedded in the wall of the cylinder 15, and its heating temperature can be maintained at 40℃~60℃ by a temperature controller (not shown in the figure) to prevent the adhesive from solidifying.

[0040] Initially, the sliding disk 33 is located at the top of the cylinder 15. During operation, an external cylinder drives the sliding disk 11, carrying the wiping brush 31, to move above the adhesive strip. Subsequently, the micro servo motor 32 receives a command from the controller (not shown) and starts, driving the lead screw 38 to rotate, causing the sliding disk 33 to move downwards by a predetermined stroke (e.g., 5 mm), pressing a measured amount of adhesive into the wiping tube 3 through the first one-way valve 17 and wetting the wiping brush 31. Next, the cylinder sliding disk 11 drives the wetted wiping brush 31 to move along the surface of the adhesive strip, completing the coating. After coating, the hot air blower 2 starts, blowing hot air through the air duct 21 to dry the adhesive strip. Finally, the micro servo motor 32 reverses, driving the sliding disk 33 to rise, and the adhesive in the adhesive bottle 12 is sucked into the lower cavity of the cylinder 15 through the second one-way valve 18 and the first hose 22, ready for the next cycle. A fixing plate 4 is fixedly connected to the outer wall of the wiping tube 3 near the bottom end; a set of Z-shaped plates 41 symmetrically distributed about the wiping tube 3 are slidably connected to the fixing plate 4; the horizontal plates at the bottom of the pair of Z-shaped plates 41 are arranged opposite to each other and are in contact with the two sides of the wiping brush 31.

[0041] A first threaded rod 42 is threadedly connected to the horizontal plate at the top of the Z-shaped plate 41, and the bottom end of the first threaded rod 42 is rotatably connected to the top of the fixed plate 4. During operation, the Z-shaped plate 41 is used, and the wiping brush 31 is located between the opposite surfaces of the lower horizontal plates of the pair of Z-shaped plates 41. This can prevent the wiping brush 31 from bending during long-term wiping, effectively improving the service life of the wiping brush 31. The Z-shaped plate 41 can be adjusted downward or upward by the first threaded rod 42 to accommodate wiping brushes 31 of different lengths.

[0042] Working principle: During operation, the sliding disk 33 is first moved upward from the bottom of the cylinder 15, and the adhesive enters through the second one-way valve 18 and the first hose 22. Then, the space between the sliding disk 33 and the bottom of the cylinder 15 is filled with adhesive. The micro servo motor 32 then operates to ensure the downward movement distance of the sliding disk 33, allowing the adhesive to be discharged through the wiping brush 31. After completion, the sliding disk 33 is moved upward again to refill the space with adhesive. This process is repeated to complete the wiping operation. At the same time, the discharge valve 16 can drain the adhesive when it is not in use. The cylinder 15 and other parts have heating wires to prevent the adhesive from solidifying. The length of the lead screw 38 and the stroke of the micro servo motor 32 must ensure that the sliding disk 33 can descend to the position closest to the bottom of the cylinder 15 to discharge the adhesive in the cavity as completely as possible, while avoiding interference with the bottom structure of the cylinder 15.

[0043] The terms "front," "back," "left," "right," "top," and "bottom" all refer to the figures in the accompanying drawings. Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
