Description

Technical Field

[0001] This application relates to the field of solvent-resistant wipers, and more specifically, to a solvent-resistant wiper with a metering liquid dispensing function. Background Technology

[0002] In industrial production, laboratory testing, and precision instrument maintenance, it is often necessary to perform solvent-resistant wiping treatments on the surfaces of various objects. For example, in the manufacturing process of electronic components, specific solvents are used to wipe oil stains and residual impurities from the surface of components to ensure the performance of the components and the accuracy of subsequent assembly. In the laboratory, solvent-resistant wiping of the surface coating of test samples can effectively test the coating's resistance to solvents and prevent the product's durability from being affected by poor surface coating quality. In the maintenance of precision instruments, solvent-resistant wiping removes contaminants from the instrument surface and key components, which can extend the service life of the instrument and ensure its stable operation. As these fields increasingly demand higher quality and efficiency in wiping, solvent-resistant wiping operations are gradually shifting from traditional manual wiping to mechanized and automated wiping, leading to the development of various solvent-resistant wiping devices. These devices typically have wiping components that can simulate manual wiping actions, achieving efficient wiping of object surfaces, effectively reducing labor intensity, and also improving wiping consistency to some extent. However, in solvent-resistant wiping, the precise control and addition of the wiping liquid is one of the key factors affecting the wiping effect. If too little liquid is used, the wiping may be incomplete, failing to completely remove contaminants from the object's surface, thus affecting the quality of subsequent processes or the normal operation of the instrument. If too much liquid is used, it will result in liquid waste, increase production costs, and excess liquid may seep into sensitive components inside the object, causing damage or performance failure. It may also cause new contamination problems due to liquid residue. Currently, most solvent-resistant wiping instruments use manual dripping in the liquid addition stage. This manual dripping method relies entirely on the operator's experience and skill to control the amount and position of the liquid. Due to individual differences in manual operation and the tendency to become fatigued during long-term operation, it is difficult to maintain a consistent amount of liquid each time, and the dripping position is also prone to deviation, which seriously affects the stability of wiping quality. At the same time, it cannot meet the requirements of wiping efficiency and consistency in mass production or large-scale testing.

[0003] Therefore, it is necessary for the inventors to design a new solvent-resistant wiping device with quantitative liquid dispensing to overcome the above problems. Summary of the Invention

[0025] like Figure 1-4As shown, a solvent-resistant wiping device with quantitative dispensing includes a wiping device body 1. A wiping assembly 2 is disposed on the wiping device body 1. The wiping assembly 2 is the core component for achieving the solvent-resistant wiping function. Its specific structural form is diverse; for example, it can be a structure composed of a wiping head and a wiping drive mechanism. The wiping head can be made of a material that can withstand the corrosion of various solvents. The wiping drive mechanism can drive the wiping head to move according to a preset trajectory and speed to complete the wiping operation on the object being wiped. Simultaneously, a dispensing assembly is disposed on the wiping device body 1 and above the wiping assembly 2. The main function of the dispensing assembly is to quantitatively add the required liquid to the wiping assembly 2. This liquid can be a solvent, cleaning agent, etc., used for wiping. The quantitative dispensing by the dispensing assembly ensures accurate liquid usage during the wiping process, thereby improving the wiping effect and avoiding the impact of improper liquid usage on the wiping quality. The liquid dispensing assembly specifically includes a support assembly, a liquid tank assembly, and a metering assembly. The support assembly is mounted on the wiping device body 1, and its main function is to provide stable support for the liquid tank assembly, ensuring that the liquid tank assembly can be firmly fixed to the wiping device body 1 and positioned above the wiping assembly 2. The liquid tank assembly is fixedly installed via the support assembly and is used to store the liquid to be dispensed. The metering assembly is located at the outlet of the liquid tank assembly and is connected to the inside of the liquid tank assembly. It is used to quantitatively control the liquid flowing out of the liquid tank assembly, ensuring that the amount of liquid dispensed onto the wiping assembly 2 remains consistent each time. Specifically, the support assembly includes a fixing plate 3, a connector 16, and a fixing ring 17. The fixing plate 3 is fixedly installed on the wiping device body 1. Various common connection methods can be used, such as bolting, welding, or bonding, as long as sufficient connection strength and stability are ensured between the fixing plate 3 and the wiping device body 1. The connector 16 is fixedly connected to the fixing plate 3. The structure of the connector 16 can be selected according to actual needs, such as a straight rod or a bent rod. Its length can also be adjusted according to the required installation height of the liquid tank assembly to ensure that the liquid tank assembly is in a suitable position. The fixing ring 17 is located at the other end of the connector 16 and is adapted to the liquid tank assembly. That is, the size and shape of the fixing ring 17 match the external contour of the liquid tank assembly, thereby stably fixing the liquid tank assembly within the fixing ring 17. In practical applications, the structure of the support assembly is not limited to this. For example, a frame-type support structure formed by connecting multiple support rods can be used, or an adjustable-height lifting support structure can be used. The height of the support can be adjusted to meet the installation requirements of liquid tank assemblies of different heights, as long as it can achieve stable support and fixation of the liquid tank assembly. Furthermore, the fixing ring 17 is arranged in a ring shape. This ring structure can better fit against the cylindrical outer wall of the liquid tank assembly, improving the fixing effect of the liquid tank assembly. A rubber ring 18 is provided on the inner wall of the fixing ring 17 to increase friction. The rubber ring 18 can make close contact with the outer wall of the liquid tank assembly. By increasing the friction between the two, it further prevents the liquid tank assembly from sliding or rotating within the fixing ring 17, ensuring the stability of the liquid tank assembly installation. Of course, in addition to using the rubber ring 18 to increase friction, raised textures, elastic protrusions, or other structures can also be provided on the inner wall of the fixing ring 17 to similarly increase friction and achieve stable fixing of the liquid tank assembly. The liquid tank assembly includes a liquid tank body 4 and a filling port. The liquid tank body 4 is mounted on the wiping device body 1 via a bracket assembly. It has an internal cavity for storing liquid. The shape of the liquid tank body 4 can be designed according to the actual amount of liquid to be stored and the size of the installation space; common shapes include cylindrical and square. The filling port is located on the liquid tank body 4. Operators can inject the liquid to be added into the liquid tank body 4 through the filling port. To prevent liquid from overflowing from the filling port during device operation, a sealing cap is usually installed on the filling port. The sealing cap and the filling port can be connected by threads, snap-fit ​​connections, or other methods to achieve a tight seal. In practical use, the liquid tank assembly can also be equipped with a liquid level observation device, such as a transparent observation window on the side wall of the liquid tank body 4, or a liquid level sensor inside the liquid tank body 4. Through the observation window, operators can visually understand the remaining liquid level inside the liquid tank body 4. The liquid level sensor converts the liquid level information into an electrical signal and transmits it to the control system. When the liquid level is lower than a preset value, the control system can issue an alarm signal to remind operators to replenish the liquid in time. In addition, an air injection port 20 is provided on the liquid tank body 4, and an air injection component 21 is provided on the wiping device. The air outlet 22 of the air injection component 21 is connected to the air injection port 20 through an air pipe. The air injection component 21 can be an air compressor, manual air pump, or other device that can provide gas pressure. By injecting gas into the liquid tank body 4 through the air injection component 21, the pressure inside the liquid tank body 4 is increased, thereby pushing the liquid in the liquid tank body 4 to flow towards the metering component. Of course, in addition to using air injection to drive the liquid flow, the liquid's own gravity can also be used to make the liquid flow towards the metering component. In this case, it is only necessary to set the liquid tank body 4 at a higher position, so that the outlet of the liquid tank body 4 is higher than the metering component. The liquid will naturally flow towards the metering component under the action of gravity. This method does not require an additional air injection component 21, which can simplify the structure of the device and reduce manufacturing costs. The specific method used can be selected according to the actual use requirements and installation conditions.

[0026] The dispensing component includes a dispensing chamber 5 and a dispensing port 6. The dispensing chamber 5 is located at the inlet of the liquid tank assembly and has a certain volume of space inside for temporarily storing the liquid flowing in from the liquid tank assembly and dispensing the liquid quantitatively. The dispensing port 6 is located at the bottom of the dispensing chamber 5 and is connected to the interior of the dispensing chamber 5. The position of the dispensing port 6 is directly above the dispensing injection port 19 of the wiping assembly 2 in its initial state. This ensures that the liquid dripping from the dispensing port 6 falls accurately into the dispensing injection port 19 of the wiping assembly 2, avoiding liquid leakage or misplacement. In actual design, the size of the dispensing port 6 can be adjusted according to the required dripping speed and volume. For example, for scenarios requiring rapid dripping, the dispensing port 6 can be designed to be larger, while for scenarios requiring slow dripping, the dispensing port 6 can be designed to be smaller.

[0027] The component distribution chamber 5 has a circular cross-section, which facilitates the installation and movement of internal components. A component distribution roller 7 is rotatably mounted inside the component distribution chamber 5, with a certain gap maintained between the outer wall of the roller 7 and the inner wall of the chamber 5 to ensure its flexible rotation. A drip groove 8 is provided on the roller 7 at the inlet of the chamber 5. The drip groove 8 has a certain volume; when liquid flows from the liquid tank assembly into the chamber 5, it enters the drip groove 8. The volume of the drip groove 8 determines the amount of liquid dispensed each time, and therefore the volume of the drip groove 8 can be designed according to the actual required amount of liquid. To prevent liquid leakage through the gap between the component roller 7 and the inner wall of the component chamber 5, a sealing ring 9 is provided between the outer wall of the component roller 7 and the inner wall of the component chamber 5 to enhance sealing. The sealing ring 9 can fit tightly against the outer wall of the component roller 7 and the inner wall of the component chamber 5, effectively preventing liquid leakage from the gap. Furthermore, the sealing ring 9 has a groove 10 at the drip groove 8. This groove 10 is designed to ensure smooth communication between the drip groove 8 and the inlet and outlet of the component chamber 5, without affecting the inflow and outflow of liquid. The sealing ring 9 can be made of a solvent-resistant and elastic material to meet the requirements of the device in solvent-resistant environments while ensuring a good sealing effect. Besides using the sealing ring 9 for sealing, an elastic coating can also be applied to the outer wall of the component roller 7. The sealing is achieved through the tight contact between the elastic coating and the inner wall of the component chamber 5. Alternatively, a labyrinth seal structure can be used, with a complex gap structure to prevent liquid leakage. Although a sealing ring 9 is used for sealing, it will not affect the normal rotation of the component roller. A rotating rod 11 is located at the center of the dispensing chamber 5. The outer wall of the rotating rod 11 is fixedly connected to the inner wall of the dispensing roller 7, so that when the rotating rod 11 rotates, it can drive the dispensing roller 7 to rotate together inside the dispensing chamber 5. The other end of the rotating rod 11 extends to the outside of the dispensing chamber 5, and a knob 12 is located at this end. The operator can drive the rotating rod 11 and the dispensing roller 7 to rotate by rotating the knob 12, which is simple and convenient to operate. A torsion spring 13 is fixedly installed inside the dispensing roller 7 and is fixedly connected to the dispensing chamber 5. The torsion spring 13 has an elastic reset function. When the operator rotates the knob 12 to rotate the dispensing roller 7, the torsion spring 13 will deform and store elastic potential energy. When the operator releases the knob 12, the torsion spring 13 will drive the dispensing roller 7 and the rotating rod 11 to automatically reset under the action of elastic potential energy, returning to the initial position, ready for the next quantitative dispensing. This setting allows the dispensing roller 7 to automatically reset after each dispensing operation, eliminating the need for manual reset by the operator, improving the convenience of operation and work efficiency. In addition to using torsion spring 13 to achieve automatic reset, a motor-driven method can also be used. The motor drives the rotating rod 11 to rotate, and a reset program is set in the motor control system. When the dripping operation is completed, the motor drives the rotating rod 11 and the component roller 7 to reset. This method can achieve more precise control and more stable reset effect, and is especially suitable for scenarios with high automation requirements. In addition, a support column 14 with a threaded outer wall is provided at the bottom of the wiping device body 1. The number of support columns 14 can be set according to the size and weight of the wiping device body 1, usually four are set, located at the four corners of the bottom of the wiping device body 1, to ensure stable support for the wiping device body 1. Foot pads 15 are screwed onto the support columns 14. The foot pads 15 contact the ground and play a role in anti-slip and shock absorption. At the same time, since the foot pads 15 are threaded to the support columns 14, the operator can adjust the length of the foot pads 15 extending out of the support columns 14 by rotating the foot pads 15, thereby adjusting the overall height and level of the wiping device body 1, so that the wiping device body 1 can adapt to different ground conditions and ensure the stability of the device during operation. In actual operation, the solvent-resistant wiping device with quantitative dispensing function first injects the liquid to be dispensed into the liquid tank body 4 through the inlet on the liquid tank assembly. After injection, the sealing cap of the inlet is closed to prevent liquid overflow. Then, depending on the actual situation, the liquid is introduced into the dispensing chamber 5 by either air injection or gravity. If air injection is used, the air injection component 21 is activated, and the gas generated by the air injection component 21 enters the liquid tank body 4 through the air pipe from the air injection port 20, increasing the pressure inside the liquid tank body 4. Under the action of pressure, the liquid in the liquid tank body 4 flows towards the dispensing chamber 5. If gravity is used, the liquid itself flows naturally from the liquid tank body 4 to the dispensing chamber 5 using its own gravity. The liquid entering the dispensing chamber 5 flows into the drip groove 8 on the dispensing roller 7. At this time, the drip groove 8 is positioned corresponding to the liquid inlet of the dispensing chamber 5, and can smoothly receive the liquid flowing in from the liquid tank assembly. When a dripping operation is required, the operator rotates knob 12, which in turn rotates rod 11. Rod 11 further rotates component roller 7 inside component chamber 5. During the rotation of component roller 7, torsion spring 13 deforms and stores elastic potential energy. When the dripping trough 8 on component roller 7 rotates to the position corresponding to the outlet of component chamber 5, the liquid in dripping trough 8 drips out from dripping port 6 under the action of gravity. Since dripping port 6 is located directly above the dripping inlet 19 of wiping component 2 in its initial state, the dripped liquid can accurately drip into the dripping inlet 19 of wiping component 2, completing one quantitative dripping operation. After the dripping is completed, the operator releases knob 12. Under the action of elastic potential energy, torsion spring 13 drives component roller 7 and rotating rod 11 to automatically reset. The dripping trough 8 returns to the position corresponding to the inlet of component chamber 5, receiving liquid again, ready for the next dripping operation.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
