Description

Technical Field

[0001] This utility model relates to the field of endoscope processing technology, specifically to a device for modifying the superhydrophilic surface of a contamination-resistant medical endoscope. Background Technology

[0002] In the medical field, medical endoscopes are important diagnostic and treatment tools. Their surface properties directly affect the effectiveness of use and patient safety. By spraying nano-titanium dioxide coating to modify the surface of medical endoscopes with superhydrophilic properties, their anti-fouling and self-cleaning abilities can be significantly improved, effectively reducing the risk of bacterial adhesion and ensuring the safety and hygiene of medical operations. However, current technologies for spraying nano-titanium dioxide coatings onto medical endoscopes have significant drawbacks. Due to the lack of a precise coating spraying control mechanism, the coating is easily sprayed onto the non-mirror surfaces of the workpiece. This not only wastes the coating and increases production costs, but also affects the original performance and appearance of the non-mirror surfaces. The subsequent cleaning of excess coating on the non-mirror surfaces also consumes a lot of manpower and time, severely reducing production efficiency and making it difficult to meet the high-precision and high-quality production requirements of medical equipment. Therefore, there is an urgent need to develop a new type of superhydrophilic surface modification treatment equipment for medical endoscopes that can solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a superhydrophilic surface modification treatment device for antifouling medical endoscopes, in order to solve the problems mentioned in the background art, where the lack of a precise spraying control mechanism leads to the coating being easily sprayed onto the non-mirror parts of the workpiece, resulting in coating waste, affecting the performance and appearance of the workpiece, and causing time-consuming and labor-intensive cleaning with low production efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a superhydrophilic surface modification treatment device for anti-fouling medical endoscopes, comprising a base, a material placement plate being fitted onto the upper surface of the base, and a workpiece being placed on the upper surface of the material placement plate; electric push rods being fixedly installed on the upper surfaces of both ends of the base, and an mounting plate being fixedly connected to the upper end of the electric push rods; a liquid storage tank being fixedly installed on the upper surface of the mounting plate; pressure pipes being fixedly installed on the outer surfaces of both sides of the liquid storage tank; a first one-way valve being fixedly connected to one end of the pressure pipe connected to the liquid storage tank; and a second one-way valve being fixedly connected to the outer surface of the upper end of the pressure pipe away from the liquid storage tank; a piston rod being fixedly installed on the upper surface of the base; a connecting pipe being connected to the lower surface of the mounting plate; and an electrically controlled nozzle being fixedly installed at the lower end of the connecting pipe. A mounting bracket is fixedly provided on the lower surface of the mounting plate, and a sliding slide rod is installed on the lower surface of the mounting bracket. A material stop block is fixedly connected to the lower surface of the slide rod, and an extrusion ring is fixedly provided on the upper surface of the material placement plate.

[0005] Preferably, the piston rod and the pressurization tube are connected by sliding friction, and one end of the pressurization tube connected to the first one-way valve penetrates the inner surface of the liquid storage tank.

[0006] By adopting the above technical solution, the coating in the pressure tube can be pressurized by the sliding friction between the piston rod and the pressure tube when the mounting plate is raised and lowered. Then, external air is drawn in through the second one-way valve to ensure that the coating in the storage tank is stably and continuously transported to the electronically controlled nozzle through the connecting pipe, thus realizing the continuous supply of coating.

[0007] Preferably, the upper end of the connecting pipe penetrates the upper surface of the mounting plate, and the upper end of the connecting pipe is connected to the liquid storage tank.

[0008] By adopting the above technical solution, the connecting pipe passes through the mounting plate and connects with the liquid storage tank, forming a direct delivery channel from the liquid storage tank to the electronically controlled nozzle. This ensures that the paint in the liquid storage tank can flow smoothly through the connecting pipe to the electronically controlled nozzle under pressure, providing a stable source of paint for the spraying operation.

[0009] Preferably, the mounting bracket has a cross-shaped design, and a clearance hole is provided in the center of the mounting bracket. The clearance hole in the center of the mounting bracket is positioned directly opposite the lower end of the electronically controlled nozzle, and the lower surface of the electronically controlled nozzle is in contact with the upper surface of the mounting bracket.

[0010] With the above technical solution, the clearance hole of the cross-shaped mounting bracket is directly opposite the lower end of the electronically controlled nozzle, which facilitates the installation and positioning of the electronically controlled nozzle and enables the nozzle to be accurately aligned with the spraying area of ​​the workpiece. At the same time, the close fit between the electronically controlled nozzle and the mounting bracket enhances the stability of the structure and ensures the accuracy of the nozzle position during the spraying process.

[0011] Preferably, the upper end of the slide bar has a T-shaped design, and a spring connects the slide bar to the mounting bracket.

[0012] Using the above technical solution, the T-shaped design at the upper end of the slide bar, in conjunction with the spring, allows the slide bar to slide up and down within the mounting frame. When the mounting plate descends, the slide bar drives the stop block to fit against the workpiece, and the spring is compressed. When the mounting plate rises, the spring resets, causing the slide bar and the stop block to rise, thus realizing the automatic lifting and resetting of the stop block, which facilitates the control of the workpiece spraying area.

[0013] Preferably, the baffle block has a fan-shaped design, and the inner surface of the baffle block is in contact with the outer surface of the workpiece. The upper outer surface of the baffle block directly above the workpiece has a notch, and the inner surface of the extrusion ring has a downward-facing sloping surface design.

[0014] Using the above technical solution, the inner surface of the fan-shaped baffle block is in contact with the outer side of the workpiece, and the mirror part of the workpiece is exposed only through its upper notch. This can effectively prevent paint from being sprayed into the non-mirror area. The inclined design of the extrusion ring extrudes the baffle block when the mounting plate descends, making it fit tightly against the workpiece. This not only accurately limits the spraying range, but also provides a stable clamping effect on the workpiece, preventing the workpiece from shaking during the spraying process and improving the spraying accuracy.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the anti-fouling medical endoscope superhydrophilic surface modification treatment equipment: 1. The electric push rods on the upper surfaces of both ends of the base can drive the mounting plate to rise and fall. The connecting pipe and the electric control nozzle connected to the lower surface of the mounting plate move accordingly. When the electric push rod pushes the mounting plate down, the baffle block at the lower end of the slide rod first fits against the outer surface of the workpiece, leaving only the mirror part of the workpiece for spraying. This effectively prevents the paint from being sprayed onto the non-mirror part of the workpiece, achieving precise spraying and avoiding paint waste and contamination of the non-mirror part. 2. The piston rod on the upper surface of the base is slidably and frictionally connected to the pressurizing pipe. During the lifting and lowering of the mounting plate, the piston rod can pressurize the paint in the pressurizing pipe. The pressurizing pipe pressurizes the liquid storage tank through the first one-way valve, and then draws in external air through the second one-way valve. The paint is then transported to the electronically controlled nozzle through the connecting pipe, ensuring a stable and continuous supply of paint and improving spraying efficiency. 3. The inner surface of the extrusion ring on the upper surface of the material plate is designed with a downward-facing slope towards the workpiece. When the mounting plate descends, the baffle block is pressed against the workpiece by the slope of the extrusion ring, preventing the workpiece from shaking during spraying and better controlling the spraying area. The mounting bracket has a cross-shaped design with a clearance hole in the center facing the lower end of the electronically controlled nozzle, which facilitates the installation and spraying operation of the electronically controlled nozzle. It works in conjunction with the electronically controlled nozzle, slide bar, and other structures to improve spraying quality and efficiency in many aspects, such as fixing the workpiece, precise positioning, and controlling the spraying range, reducing subsequent cleaning processes, lowering production costs, and meeting the high-precision and high-quality production requirements of medical 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 Figures 1-6 This utility model provides a technical solution: a device for modifying the superhydrophilic surface of a dirt-resistant medical endoscope.

[0020] Example 1: This example discloses: a base 1, a material placement plate 2 is fitted onto the upper surface of the base 1, and a workpiece 3 is placed on the upper surface of the material placement plate 2. Electric push rods 4 are fixedly installed on the upper surfaces of both ends of the base 1, and an mounting plate 5 is fixedly connected to the upper end of the electric push rods 4. A liquid storage tank 6 is fixedly installed on the upper surface of the mounting plate 5. A pressure pipe 7 is fixedly installed on the outer surfaces of both sides of the liquid storage tank 6. A first one-way valve 8 is fixedly connected to one end of the pressure pipe 7 connected to the liquid storage tank 6. A second one-way valve 9 is fixedly connected to the outer surface of the upper end of the pressure pipe 7 away from the liquid storage tank 6. A piston rod 10 is fixedly installed on the upper surface of the base 1. A connecting pipe 11 is connected to the lower surface of the mounting plate 5, and an electrically controlled nozzle 12 is fixedly installed at the lower end of the connecting pipe 11. The piston rod 10 and the pressure tube 7 are connected by sliding friction, and one end of the pressure tube 7 connected to the first one-way valve 8 penetrates the inner surface of the liquid storage tank 6. The upper end of the connecting pipe 11 penetrates the upper surface of the mounting plate 5, and the upper end of the connecting pipe 11 is connected to the liquid storage tank 6. The base 1 is fitted with a material plate 2, and the workpiece 3 is placed on the material plate 2. The liquid storage tank 6 is fixed on the upper surface of the mounting plate 5 and stores nano titanium dioxide coating inside. The upper end of the connecting pipe 11 passes through the mounting plate 5 and connects to the liquid storage tank 6, and the lower end is connected to the electrically controlled nozzle 12 to form a coating delivery channel. After the electric push rods 4 at both ends of the base 1 are started, they drive the mounting plate 5 to rise and fall vertically. When the mounting plate 5 falls, the electrically controlled nozzle 12 moves down to the spraying position above the workpiece 3. When it rises, the nozzle moves away from the workpiece 3 to facilitate loading and unloading. The piston rod 10 on the base 1 remains stationary. During the lifting and lowering of the mounting plate 5, the pressure pipe 7 slides along the piston rod 10. When the mounting plate 5 descends, the piston in the pressure pipe 7 is compressed, and the first one-way valve 8 opens, forcing air into the storage tank 6. When the mounting plate 5 rises, a negative pressure is formed in the pressure pipe 7, and the second one-way valve 9 opens, drawing in external air. At the same time, the first one-way valve 8 closes to prevent air backflow. This process achieves continuous pressurization of the coating in the storage tank 6 through the sliding friction between the piston rod 10 and the pressure pipe 7, ensuring that the coating is stably delivered to the electrically controlled nozzle 12 via the connecting pipe 11. After receiving the electrical signal, the electrically controlled nozzle 12 opens. Under the pressure, the coating in the storage tank 6 is sprayed out from the nozzle through the connecting pipe 11 to perform superhydrophilic modification treatment on the surface of the workpiece 3.

[0021] Example 2: This example discloses the following based on Example 1: A mounting bracket 13 is fixedly provided on the lower surface of the mounting plate 5, and a sliding slide rod 14 is installed on the lower surface of the mounting bracket 13. A material stop block 15 is fixedly connected to the lower surface of the slide rod 14, and an extrusion ring 16 is fixedly provided on the upper surface of the material plate 2. The mounting bracket 13 has a cross-shaped design, and a clearance hole is provided in the center of the mounting bracket 13. The clearance hole in the center of the mounting bracket 13 is positioned directly opposite the lower end of the electronically controlled nozzle 12, and the lower surface of the electronically controlled nozzle 12 is in contact with the upper surface of the mounting bracket 13. The upper end of the slide bar 14 has a T-shaped design, and a spring connects the slide bar 14 to the mounting bracket 13; The stop block 15 is fan-shaped, and the inner surface of the stop block 15 is in contact with the outer surface of the workpiece 3. The upper outer surface of the stop block 15 directly above the workpiece 3 has a notch. The inner surface of the extrusion ring 16 is a downward inclined surface facing the workpiece 3. A clearance hole is provided in the center of the cross-shaped mounting bracket 13 on the lower surface of the mounting plate 5, which is aligned with the lower end of the electronically controlled spray head 12 to facilitate spray head installation and spraying. The upper end of the slide rod 14 is T-shaped and slidably connected to the mounting bracket 13. The spring between the two keeps the slide rod 14 in the extended state in the initial state, and the fan-shaped baffle block 15 at the lower end is suspended above the workpiece 3. The inner side of the extrusion ring 16 on the material placement plate 2 is an inclined surface facing the workpiece 3.

[0022] When the electric push rod 4 pushes the mounting plate 5 down, the stop block 15 at the lower end of the slide rod 14 first contacts the inclined surface of the extrusion ring 16. As the mounting plate 5 continues to descend, the inclined surface of the extrusion ring 16 presses against the stop block 15, causing the slide rod 14 to slide upward along the mounting frame 13 and compress the spring until the inner surface of the stop block 15 is tightly attached to the outer surface of the workpiece 3. At this time, the stop block 15 only leaves the area corresponding to the upper notch of the mirror part of the workpiece 3, and the non-mirror part is blocked to prevent the paint from being sprayed into the non-treated area. The inclined surface of the extrusion ring 16 continues to press against the stop block 15, so that the stop block 15 generates centripetal pressure on the workpiece 3. With the support of the material plate 2, the workpiece 3 is firmly clamped to prevent the workpiece 3 from shaking during the spraying process and to ensure accurate spraying position. The sliding pressurization process of piston rod 10 and pressurizing pipe 7 is the same as in embodiment 1. The coating in the liquid storage tank 6 is sprayed out by the electrically controlled nozzle 12 through the connecting pipe 11. At this time, the baffle block 15 has precisely defined the spraying area. The coating only acts on the mirror part of the workpiece 3 to achieve anti-fouling and super-hydrophilic modification treatment. After the spraying is completed, the electric push rod 4 drives the mounting plate 5 to rise, the slide rod 14 is reset under the action of the spring, and the baffle block 15 is separated from the workpiece 3, which makes it easy to pull out the entire material plate 2 to remove the material.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
