Description

Technical Field

[0001] This utility model relates to the field of cleanroom cloth cleaning technology, specifically an automatic spraying and wiping mechanism for cleaning and rolling cleanroom cloths. Background Technology

[0002] In industries such as precision machining, optical component manufacturing, LCD panels, and semiconductors, the cleanliness of production equipment tables, guide rails, and the products themselves are key factors affecting product yield. Therefore, it is often necessary to use cleanroom wipes for cleaning, so it is essential to ensure that the cleanroom wipes are not contaminated before use.

[0003] Existing methods for cleaning lint-free cloths typically include two approaches, one of which is manual wiping. Operators must hold a lint-free cloth or cotton swab, dip it in alcohol, acetone, or a specialized cleaning agent, and wipe the surface to be cleaned. This method is inefficient, has a limited cleaning area per operation, and is slow, making it completely unsuitable for modern production lines. Secondly, there are simple semi-automatic wiping devices. Although mechanical wiping devices such as fixed rollers and scrapers exist on the market, which reduce direct human contact to some extent, these devices are limited in function and have a very low degree of integration: on the one hand, they lack an automatic solvent supply function, and manual application of solvent to the surface to be cleaned or application of solvent to the wiping parts is still required, making it impossible to achieve continuous automated production; on the other hand, the equipment lacks an automatic lint-free cloth replacement and recycling structure, and the replacement of wiping materials depends entirely on manual labor. In continuous operation scenarios, lint-free cloths that have been contaminated with pollutants will remain on the wiping path, repeatedly contacting the surface to be cleaned, causing "cross-contamination" and resulting in a significant decrease in cleaning effect.

[0004] To address these issues, we designed an automated spraying and wiping mechanism for cleaning and rolling lint-free cloths. Utility Model Content

[0005] The purpose of this invention is to provide an automatic spraying and wiping mechanism for cleaning and rolling lint-free cloths, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an automatic spraying and wiping mechanism for cleaning and winding lint-free cloths, including a base body and a cloth roll body. A spraying mechanism is provided on one side of the base body. Inside the base body, along the conveying direction of the cloth roll body, a cloth roll assembly and a sliding plate assembly are arranged sequentially. The cloth roll assembly includes an unwinding drum and a rewinding drum rotatably connected to the base body and symmetrically arranged. A cloth roll tensioning shaft assembly is provided inside the base body and is located between the unwinding drum and the rewinding drum. The spraying mechanism includes an alcohol spray gun, an alcohol tank body, and an alcohol tank mounting plate. The alcohol tank body is connected to one side of the base body through the alcohol tank mounting plate. The nozzle of the alcohol spray gun faces the cloth surface of the cloth roll body. The slide plate assembly is located below the conveying path of the fabric roll body and is used to wipe the fabric roll body after spraying. The fabric roll body is led out from the unwinding drum, tensioned by the fabric roll tensioning shaft assembly, passes through the spraying area of ​​the alcohol spray gun, and then overlaps the slide plate assembly for wiping. A power mechanism that is connected to the fabric roll assembly is also provided on one side of the base body.

[0007] Furthermore, the power mechanism includes a drive motor, which is connected to the fabric winding assembly to drive the fabric winding body to wind.

[0008] Furthermore, the fabric tensioning shaft assembly includes at least two fabric tensioning shafts, which are mounted on the machine base body via bearings and are used to guide and tension the fabric body.

[0009] Furthermore, the slide assembly includes a guide block, at least two guide shafts, and an elastic spring sleeved on the guide shafts; the guide shafts are vertically connected between the guide block and the machine base body, and the elastic springs are used to buffer and adjust the bonding pressure between the guide block and the roll body, so that the guide block can adaptively adjust its position according to the tension of the roll body.

[0010] Furthermore, the base body is also provided with a base guide rod and a base sealing plate. The base guide rod is used to guide the movement of the slide plate assembly, and the base sealing plate is used to close the side of the base body.

[0011] Furthermore, a damper is provided on the unwinding drum shaft of the fabric roll assembly to provide reverse tension to prevent the fabric roll body from loosening.

[0012] Furthermore, the spraying mechanism also includes an alcohol pipeline for connecting the alcohol tank body and the alcohol spray gun, and a solenoid valve is provided on the alcohol pipeline.

[0013] Furthermore, at least four foot feet are connected to the bottom of the base body, and the foot feet are height-adjustable suction cup feet.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The drive motor provides power to the cloth roll assembly, which, together with the cloth roll tensioning shaft assembly, maintains the flat transmission of the cloth roll body. It can replace manual operation and solve the problems of low efficiency and limited area of ​​manual cleaning. At the same time, the solenoid valve of the alcohol pipeline controls the spray volume, and combined with the uniform movement of the cloth roll, it ensures uniform solvent adhesion, avoids the unevenness and waste of manual spraying, and further adapts to modern production lines.

[0015] 2. The constant tension of the fabric roll tensioning shaft assembly prevents the fabric roll from loosening or breaking, ensuring a tight fit with the slide plate assembly; the elastic spring adaptively adjusts the pressure of the guide block to suit different surface cleaning needs. After use, the fabric roll is automatically recycled via the take-up drum, avoiding cross-contamination caused by contaminated fabric remaining on the wiping path, thus solving the problem of poor cleaning effect in traditional semi-automatic equipment.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: an automatic spraying and wiping mechanism for cleaning and winding lint-free cloths, including a base body 12 and a cloth roll body 3. A spraying mechanism is provided on one side of the base body 12. Inside the base body 12, along the conveying direction of the cloth roll body 3, a cloth roll assembly 7 and a sliding plate assembly 1 are sequentially arranged. The cloth roll assembly 7 includes an unwinding drum and a rewinding drum symmetrically connected within the base body 12. A cloth roll tensioning shaft assembly 2 is provided inside the base body 12, located between the unwinding drum and the rewinding drum. The spraying mechanism includes alcohol. The unit consists of a spray gun 4, an alcohol tank body 6, and an alcohol tank mounting plate 5. The alcohol tank body 6 is connected to one side of the base body 12 via the alcohol tank mounting plate 5. The nozzle of the alcohol spray gun 4 faces the fabric surface of the roll body 3. The slide plate assembly 1 is located below the transmission path of the roll body 3 and is used to wipe the roll body 3 after spraying. The roll body 3 is led out from the unwinding drum, tensioned by the roll tensioning shaft assembly 2, passes through the spraying area of ​​the alcohol spray gun 4, and then overlaps the slide plate assembly 1 for wiping. A power mechanism that is connected to the roll assembly 7 is also provided on one side of the base body 12.

[0020] It should be noted that the alcohol tank body 6 is made of transparent material and is equipped with a visible liquid level window.

[0021] In practice, the power mechanism drives the unwinding drum of the cloth roll assembly 7 to release the cloth roll body 3. After the cloth roll is tensioned by the cloth roll tensioning shaft assembly 2, it first obtains cleaning solvent through the spray area of ​​the alcohol spray gun 4, then overlaps the sliding plate assembly 1 to complete the wiping, and finally the take-up drum recovers the used cloth roll. This setting does not require the operator to hold the lint-free cloth. The cloth roll is automatically transported by the power mechanism, which improves the cleaning efficiency.

[0022] See Figure 1-4 The power mechanism includes a drive motor 9, which is connected to the fabric roll assembly 7 to drive the fabric roll body 3 to roll.

[0023] In practice, the drive motor 9 is connected to the fabric roll assembly 7 to provide stable power for the release of the unwinding drum and the retraction of the fabric roll body 3, ensuring that the fabric roll is transmitted at a uniform speed according to the set speed. This setting does not require manual pushing or adjustment of the fabric roll, thus automating the cleaning process.

[0024] See Figure 1-4 The fabric tensioning shaft assembly 2 includes at least two fabric tensioning shafts, which are mounted on the machine base body 12 via bearings and are used to guide and tension the fabric body 3.

[0025] In practice, at least two fabric tensioning shafts are mounted on the machine base 12 via bearings, creating tension between the unwinding drum and the take-up drum. This guides the fabric roll body 3 to remain flat and taut. After the fabric roll body 3 is taut, it fits more tightly with the slide plate assembly 1, preventing inadequate cleaning of certain areas due to the looseness of the fabric roll body 3. The uniform tension also prevents wrinkles or damage to the fabric roll body 3 during transmission, ensuring that the fabric roll body 3 is not additionally contaminated before use.

[0026] See Figure 1-4 The slide assembly 1 includes a guide block, at least two guide shafts, and elastic springs sleeved on the guide shafts. The guide shafts are vertically connected between the guide block and the base body 12. The elastic springs are used to buffer and adjust the bonding pressure between the guide block and the roll body 3, so that the guide block can adaptively adjust its position according to the tension of the roll body 3.

[0027] In practice, the guide shaft is vertically connected to the guide block and the machine base body 12, and the elastic spring is sleeved on the guide shaft. When the tension of the roll body 3 changes, the elastic spring can automatically extend and retract to adjust the bonding pressure between the guide block and the roll body 3.

[0028] See Figure 1-4 The base body 12 is also provided with a base guide rod 10 and a base sealing plate 11. The base guide rod 10 is used to guide the movement of the slide plate assembly 1, and the base sealing plate 11 is used to close the side of the base body 12.

[0029] In practice, the base guide rod 10 provides guidance for the movement of the slide plate assembly 1, and the base sealing plate 11 seals the side of the base body 12 to isolate external dust.

[0030] See Figure 1-4 A damper is provided on the unwinding drum shaft of the fabric assembly 7 to provide reverse tension to prevent the fabric body 3 from loosening.

[0031] In practice, the damper is set on the unwinding drum shaft of the fabric roll assembly 7 to provide reverse tension, which balances the tension of the take-up drum and ensures that the fabric roll body 3 remains flat when released. This setting can prevent surface friction or dust adhesion caused by loose stacking of the fabric roll body 3, ensure that the fabric roll body 3 is dust-free before use, and the reverse tension can offset the instantaneous tension of the take-up drum, avoiding the fabric roll body 3 being stretched and deformed due to sudden speed changes.

[0032] See Figure 1-4 The spraying mechanism also includes an alcohol pipeline, which connects the alcohol tank body 6 to the alcohol spray gun 4. A solenoid valve is installed on the alcohol pipeline.

[0033] In practice, the alcohol pipeline connects the alcohol tank body 6 to the alcohol spray gun 4, and the solenoid valve controls the on / off of the pipeline, allowing the amount of alcohol sprayed to be adjusted according to cleaning needs.

[0034] See Figure 1-4 The bottom of the base body 12 is connected to at least four foot feet 8, which are height-adjustable suction cup feet.

[0035] In practice, at least four height-adjustable suction cup grounding bodies 8 are connected to the bottom of the base body 12. The height is adjusted to keep the equipment level, and the suction cups adhere to the ground to fix the equipment.

[0036] Working principle: The unused roll body 3 is installed on the unwinding drum of the roll assembly 7, one end of the roll is led out, and it passes through at least two roll tensioning shafts of the roll tensioning shaft assembly 2 in sequence, and is finally fixed on the take-up drum. The drive motor 9 on one side of the base body 12 starts and connects to the cloth winding assembly 7 through the transmission structure, providing power for the unwinding and rewinding drums. During the transmission of the cloth winding body 3, multiple cloth tensioning shafts of the cloth tensioning shaft assembly 2 guide the direction of the cloth winding through the rotation of bearings, while maintaining constant tension to ensure that the cloth winding body 3 always remains flat. This method avoids loosening that would result in poor adhesion with the subsequent wiping structure, and also prevents wrinkles or damage to the cloth winding body 3 due to excessive tension. Subsequently, the operator can adjust the flow and opening of the alcohol pipeline by controlling the solenoid valve on the alcohol pipeline according to the needs of the surface to be cleaned. After the solenoid valve is opened, the cleaning solvent is delivered along the pipeline to the alcohol spray gun 4, which sprays the solvent. The spray gun 4 sprays the alcohol onto the fabric surface of the roll body 3. Because the roll body 3 maintains a uniform speed and flat state under the action of the roll tension shaft assembly 2, the spraying area of ​​the alcohol spray gun 4 can evenly cover the roll surface, ensuring that each part of the fabric surface is covered with an appropriate amount of cleaning solvent. When the roll body 3 fluctuates in position due to slight changes in tension during transmission, the elastic spring will automatically extend and retract, driving the guide block to adjust its position synchronously, always maintaining a tight fit with the surface of the roll body 3. At the same time, the elastic spring can adjust the bonding pressure in real time according to the tension of the roll body 3. After being wiped, the roll body 3 moves along the transmission path to the take-up drum of the roll assembly 7, and is automatically wound and recycled by the take-up drum under the drive of the drive motor 9.
