Description

Technical Field

[0001] The present invention relates to the technical field of antistatic tube production devices, and particularly to an antistatic tube production device and method with a grooving and spraying function. Background Art

[0002] An antistatic tube is a specially designed tubular article used to prevent static electricity accumulation and is widely applied in aspects such as the protection and transportation of electronic products, the semiconductor industry, and precision instruments. Among them, the PFA tube has better chemical resistance. Since the PFA material is almost inert to all chemicals, it will not react with the conveying medium, ensuring a pure fluid transmission environment. Due to its excellent performance, the PFA tube is widely used in multiple fields. For example, the PFA tube can be applied to the transmission pipelines, fluid control systems, and vacuum systems of wafer processing equipment. Its corrosion resistance, cleanliness, and insulation properties all contribute to improving equipment performance and production efficiency. However, the PFA tube itself does not have an antistatic effect, and the accumulation of static electricity may cause component damage, short circuits, or even failures. Traditional antistatic PFA tubes often adopt a co-extrusion process, using high-temperature melt co-extrusion, that is, using several extruders to supply PFA raw materials and conductive raw materials to a composite die head simultaneously, so as to form conductive strips on the surface of the extruded PFA tube to make an antistatic PFA tube. However, the preparation process of the antistatic PFA tube prepared by the co-extrusion process is complex and has a high preparation difficulty. It requires multiple extruders and complex molds, increasing the production cost and equipment requirements. Moreover, the processing temperatures and chemical characteristics of the PFA raw materials and conductive raw materials need to be precisely matched, otherwise it is very easy to affect the product quality. And the conductive strip part is prone to migrate to the inner layer of the PFA tube in the high-temperature and high-pressure environment in the die head, resulting in a decrease in the cleanliness performance of the inner layer of the PFA tube. When this tube is used in the process of transporting clean fluids in the semiconductor field, the precipitation of metal ions, anions, TOC, and particles all increases significantly.

[0003] If the conductive static coating is directly applied to the surface of the PFA tube, it can also achieve the antistatic effect. Moreover, the conductive static coating will not migrate inward like the conductive strip, thus not affecting the cleanliness performance of the PFA tube, and can reduce or prevent the accumulation of static electricity. The raw materials of the surface coating of the antistatic tube mainly include: 1. Polyurethane raw materials: Polyurethane coatings are commonly used on the surface layer of antistatic tubes because they have both good mechanical strength and can provide a certain static electricity release function; 2. Polyester raw materials: Polyester coatings are commonly used antistatic coating materials, which usually combine polymers with conductive fillers to form effective antistatic protection; 3. PFA raw materials: PFA itself has good electrical insulation properties and has a certain effect on preventing static electricity accumulation. Pure PFA materials do not have significant antistatic functions. In actual applications, PFA coatings are usually combined with conductive fillers or static dissipators to make them have antistatic properties. Particularly, the antistatic tube with PFA coating has the following advantages: 1. Excellent chemical corrosion resistance: The antistatic tube with PFA coating can be effectively used in various harsh chemical environments, such as chemical transportation, transportation of corrosive gases or liquids, etc.; 2. High temperature resistance: PFA has high thermal stability and can withstand the static electricity release requirements in high temperature environments, and is widely applicable to antistatic pipelines under high temperature conditions; 3. Excellent antistatic performance: By adding conductive fillers or static dissipators, the PFA coating can effectively avoid static electricity accumulation and prevent electrostatic discharge (ESD) phenomena, effectively protecting electronic devices and sensitive components; 4. Good insulation: PFA is a good electrical insulation material and is widely used in the electrical and electronic fields.

[0004] Therefore, for the antistatic PFA tube prepared by applying the conductive static coating on the surface of the PFA tube, although the equipment requirements are reduced and the difficulty of the preparation process is lowered, it is often difficult to ensure the coating uniformity and coating adhesion of the conductive static coating on the surface of the PFA tube, and the use effect of the spraying device for applying the conductive static coating is not ideal.

[0005] The existing antistatic tube coating devices have the following technical problems: 1. Coating uniformity problem: The antistatic coating needs to evenly cover the surface of the pipe to ensure the effective release of static electricity; if the coating is uneven, static electricity may still accumulate in some areas, thus reducing the antistatic effect; 2. Insufficient coating adhesion: The adhesion of the antistatic coating to the surface of the pipe is the key to ensuring its long-term effectiveness; if the adhesion is insufficient, the coating may fall off or be damaged during use, resulting in the loss of the antistatic effect; 3. Low degree of automation and control accuracy: The degree of automation of the coating device is crucial for improving production efficiency and ensuring coating quality. A high-precision coating device can automatically complete steps such as spraying and curing, reducing human operation errors and ensuring product production quality. Summary of the Invention

[0020] Further, the axis of the air inlet cylinder is perpendicular to the axis of the installation base, and the support inclined plate is located between the installation base and the telescopic rod.

[0021] A method for a production device of an antistatic pipe with a grooving and spraying function includes:

[0022] S1. Lead out one end of the PFA pipe from the pipe reel, start the second motor, and convey the led-out PFA pipe through the first reel on the second bracket and the second reel on the third bracket to the limiting roller on one side of the third bracket. Start the Z-axis motor, the X-axis motor, and the first motor respectively, and put the PFA raw material added with a conductive material into the feeding funnel above the feeding assembly.

[0023] S2. Start the Z-axis motor to drive the connecting piece to rotate. The rotation of the connecting piece drives the lower Z-axis lead screw to move in the Z-axis direction. The movement of the Z-axis lead screw drives the first slider connected thereto to move up and down in the Z-axis direction, thereby driving the support plate connected to the first slider to move up and down in the Z-axis direction, so as to adjust the position of the tool below the feeding assembly in the Z-axis direction. At the same time, start the X-axis motor, drive the X-axis lead screw to rotate in the horizontal direction, thereby driving the second slider above it to move in the horizontal direction, and further driving the tool below the second slider to move in the X-axis direction, so as to adjust the tool to the position where grooving is required at one end of the PFA pipe according to the position of the PFA pipe.

[0024] S3. The X-axis motor continues to operate, driving the tool below the moving component to groove the PFA tube. According to requirements, the control system controls the grooving length of the tool in the X-axis direction. After the set grooving length is reached, the control system gives a prompt and the tool stops grooving the PFA tube.

[0025] S4. At this time, the first motor starts, driving the stirring blades in the feeding cylinder connected to the first motor to rotate. The stirring blades rotate to convey the PFA raw materials falling from the feeding funnel in the feeding cylinder, and the PFA raw materials are conveyed to the feeding pipe on one side through the feeding cylinder. The PFA raw materials entering the feeding pipe continue to move downward under the action of gravity into the storage cylinder, and are discharged through the discharge port below the storage cylinder. Driven by the X-axis motor, the X-axis lead screw rotates to drive the second slider to move horizontally, and then drives the tool to move, so as to extrude the PFA raw materials from the discharge port in the tool. The second slider continues to move along the grooving position on the PFA tube, so as to coat the PFA raw materials extruded from the discharge port into the grooving opening on the PFA tube.

[0026] S5. In order to quickly solidify and form the coated PFA raw materials and prevent the coating from deforming due to external environments such as high temperature, at this time, the air source switch of the cooling component is started, and external air is absorbed at the air source switch. After the air enters the compressed air chamber, it is compressed in the compressed air chamber. When the compressed air passes through the air inlet cylinder, the gas pressure drops rapidly, resulting in a temperature decrease. The cooled air passes through the cold air chamber connected to the air inlet cylinder and is ejected from the cold air holes provided on the cold air chamber to form a low-temperature air flow. The low-temperature air flow is sprayed onto the surface layer of the PFA tube after being coated with the PFA raw materials to cool and solidify the coating of the PFA tube, so as to achieve a good coating effect of the PFA tube and make the PFA tube have antistatic properties.

[0027] (3) Beneficial effects

[0028] A production device and method for an antistatic tube with grooving and spraying functions provided by the present invention have the following beneficial effects compared with the prior art:

[0029] 1. An antistatic tube production device with a grooving and spraying function according to the present invention includes a workbench. A conveying component is arranged in the middle of the workbench, and a moving component and a cooling component are arranged on both sides of the workbench. An inlet component is connected to one side of the moving component. The moving component includes a base located on one side of the workbench. A support frame is arranged on the base. A Z-axis motor is arranged on one side of the support frame. A connecting piece is arranged below the Z-axis motor. A Z-axis lead screw is connected below the connecting piece. A first slider is arranged on the Z-axis lead screw. The first slider is connected to a support plate. An X-axis motor is arranged on one side of the support plate. The X-axis motor is connected to an X-axis lead screw. A second slider is arranged on the X-axis lead screw. The overall structure of the antistatic tube production device with a grooving and spraying function is simple, easy to install and use, and convenient for workers to operate and maintain.

[0030] 2. For the antistatic tube production device with a grooving and spraying function according to the present invention, by starting the Z-axis motor to drive the connecting piece to rotate, the rotation of the connecting piece drives the lower Z-axis lead screw to move in the Z-axis direction. The movement of the Z-axis lead screw drives the connected first slider to move up and down in the Z-axis direction. The movement of the first slider drives the support plate on one side to move up and down in the Z-axis direction, so as to adjust the position of the tool of the inlet component in the Z-axis direction as needed. In addition, when the X-axis motor is started, it drives the X-axis lead screw to rotate in the horizontal direction, driving the second slider above it to move in the horizontal direction, and then driving the tool below the second slider to move in the X-axis direction, so as to adjust the tool to the position where grooving is required at one end of the PFA tube according to the position of the PFA tube, and perform grooving treatment on the PFA tube. And through the first motor, it drives the stirring blades in the feed cylinder to rotate to convey the PFA raw material in the feed cylinder, convey it to the feed pipe on one side through the feed cylinder, and discharge it through the discharge port below the storage cylinder. Driven by the X-axis motor, the X-axis lead screw rotates to drive the second slider to move in the horizontal direction, and then drives the tool to move, so as to extrude the PFA raw material from the discharge port in the tool. The second slider continues to move along the grooving position on the PFA tube, so as to coat the PFA raw material extruded from the discharge port into the grooving opening on the PFA tube. The linkage design of the moving component and the inlet component is different from the traditional way of separately designing a grooving device and a coating device. This device combines the grooving and coating functions of the PFA tube, designs the discharge port inside the tool, and coats the PFA tube in time after grooving, which helps to save costs, reduce the error of manual operation, ensure the product production quality, and improve the working efficiency of grooving and coating the antistatic tube.

[0031] 3. In the production device of an antistatic tube with a grooving and spraying function according to the present invention, the designed cooling component includes a support. A cylinder is arranged on the support, and a telescopic rod is arranged inside the cylinder. An installation base is arranged on the support inclined plate, and a compressed air chamber is arranged on the installation base. An air source switch is arranged on one side of the compressed air chamber, and an air inlet cylinder is arranged above the compressed air chamber. One end of the air inlet cylinder is connected to a cold air chamber, and cold air holes are arranged on the cold air chamber; In order to quickly cure and form the coated PFA raw material and prevent the coating from deforming due to external environments such as high temperature, start the air source switch of the cooling component. The air source switch absorbs external air, compresses the air in the compressed air chamber. When the compressed air passes through the air inlet cylinder, the gas pressure drops rapidly, resulting in a temperature decrease. The cooled air passes through the cold air chamber connected to the air inlet cylinder and sprays out from the cold air holes arranged on the cold air chamber to form a low-temperature air flow. The low-temperature air flow is sprayed onto the surface layer of the PFA tube after being coated with the PFA raw material to cool and cure the coating of the PFA tube, so that the coating adheres evenly in the grooves of the PFA tube and is not easy to fall off or be damaged, thereby enabling the PFA tube to have good antistatic performance.

[0059] Refer to Figures 1 to 11 , a method for a production device of an antistatic tube with grooving and spraying functions, comprising the following steps:

[0060] S1. Lead one end of the PFA tube 407 out from the pipe reel 404, start the second motor 403, and convey the led-out PFA tube 407 through the first reel 412 on the second bracket 405 and the second reel 411 on the third bracket 406 to the limiting roller 409 on one side of the third bracket 406. Start the Z-axis motor 203, the X-axis motor 207, and the first motor 302 respectively, and put the PFA raw material added with a conductive material into the feed hopper 301 above the feeding assembly 3;

[0061] S2. The started Z-axis motor 203 drives the connecting piece 204 to rotate. The rotation of the connecting piece 204 drives the lower Z-axis lead screw 205 to move in the Z-axis direction. The movement of the Z-axis lead screw 205 drives the first slider 210 connected thereto to move up and down in the Z-axis direction, thereby driving the support plate 206 connected to the first slider 210 to move up and down in the Z-axis direction, so as to adjust the position of the cutter 307 below the feeding assembly 3 in the Z-axis direction. At the same time, the X-axis motor 207 is started to drive the X-axis lead screw 208 to rotate in the horizontal direction, thereby driving the second slider 209 above it to move in the horizontal direction, and further driving the cutter 307 below the second slider 209 to move in the X-axis direction, so as to adjust the cutter 307 to the position where one end of the PFA tube 407 needs to be grooved according to the position of the PFA tube 407;

[0062] S3. The X-axis motor 207 continues to operate to drive the cutter 307 below the moving assembly 2 to groove the PFA tube 407, and controls the grooving length of the cutter 307 in the X-axis direction as required. After reaching the set grooving length, the control system issues a prompt, and the cutter 307 stops grooving the PFA tube 407;

[0063] S4. At this time, the first motor 302 is started to drive the stirring blade 304 in the feeding cylinder 303 connected to the first motor 302 to rotate. The stirring blade 304 rotates to convey the PFA raw material falling from the feeding funnel 301 in the feeding cylinder 303, and conveys it to the feeding pipe 305 on one side through the feeding cylinder 303. The PFA raw material entering the feeding pipe 305 continues to move downward under the action of gravity to the storage cylinder 306, and discharges through the discharge port 308 below the storage cylinder 306. Driven by the X-axis motor 207, the X-axis lead screw 208 rotates to drive the second slider 209 to move in the horizontal direction, and further drives the cutter 307 to move, so as to extrude the PFA raw material from the discharge port 308 in the cutter 307. The second slider 209 continues to move along the grooving position on the PFA tube 407, so as to coat the PFA raw material extruded from the discharge port 308 into the grooving opening on the PFA tube 407;

[0064] S5. To enable the coated PFA raw material to quickly solidify and form, and prevent the coating from deforming due to external environments such as high temperature, at this time, the air source switch 607 of the cooling component 6 is activated to absorb external air at the air source switch 607. After the air enters the compressed air chamber 606, it is compressed in the compressed air chamber 606. When the compressed air passes through the air inlet tube 608, the gas pressure drops rapidly, resulting in a temperature decrease. The cooled air passes through the cold air chamber 609 connected to the air inlet tube 608 and is ejected from the cold air holes 610 provided on the cold air chamber 609 to form a low-temperature air flow. The low-temperature air flow is sprayed onto the surface layer of the PFA tube 407 after being coated with the PFA raw material to cool and solidify the coating of the PFA tube 407, thereby achieving a good coating effect for the PFA tube 407 and making the PFA tube 407 have antistatic properties.

10. A method for producing an antistatic pipe with a slotting and spraying function, applied to an antistatic pipe with a slotting and spraying function as claimed in any one of claims 1 to 9, characterized in that: include: S1, one end of the PFA tube is led out from the tube reel, the second motor is started, the led PFA tube is conveyed to the limiting roller on one side of the third bracket through the first reel on the second bracket and the second reel on the third bracket, the Z-axis motor, the X-axis motor and the first motor are started respectively, and the PFA raw material added with the conductive material is placed in the feeding funnel above the feeding assembly; S2. The started Z-axis motor drives the connecting piece to rotate, and the rotation of the connecting piece drives the Z-axis screw below to move in the Z-axis direction. The movement of the Z-axis screw drives the first slider connected thereto to move up and down in the Z-axis direction, thereby driving the support plate connected to the first slider to move up and down in the Z-axis direction, thereby adjusting the position of the tool below the feeding assembly in the Z-axis direction. At the same time, the X-axis motor is started to drive the X-axis screw to rotate in the horizontal direction, thereby driving the second slider above it to move in the horizontal direction, and then driving the tool below the second slider to move in the X-axis direction, thereby adjusting the tool to the position where the groove needs to be opened at one end of the PFA tube according to the position of the PFA tube; S3, the X-axis motor continues to run, driving the tool under the moving component to slot the PFA tube, and the control system controls the slotting length of the tool in the X-axis direction as needed. When the set slotting length is reached, the control system issues a prompt, and the tool stops slotting the PFA tube; S4. At this time, the first motor starts, driving the stirring blade in the feed barrel connected to the first motor to rotate. The stirring blade rotates, and the PFA raw material falling from the feed hopper is transported in the feed barrel, and then transported to the feed pipe on one side through the feed barrel. The PFA raw material entering the feed pipe continues to move downward into the storage barrel under the action of gravity, and is discharged through the discharge port below the storage barrel. Under the drive of the X-axis motor, the X-axis lead screw rotates to drive the second slider to move in the horizontal direction, and then drives the tool to move, so that the PFA raw material is squeezed out from the discharge port in the tool, and the second slider continues to move along the slotted position on the PFA tube, so that the PFA raw material squeezed out from the discharge port is coated on the slotted port on the PFA tube; S5. In order to make the coated PFA raw material solidify and form quickly and prevent the coating from being deformed due to external environment such as high temperature, at this time, the air source switch of the cooling component is started, and the outside air is absorbed through the air source switch. After the air enters the compressed air cavity, it is compressed in the compressed air cavity. When the compressed air passes through the air inlet pipe, the gas pressure drops rapidly, causing the temperature to drop. The cooled air passes through the cold air bin connected to the air inlet pipe and is ejected from the cold air holes provided on the cold air bin to form a low-temperature airflow. The low-temperature airflow is sprayed onto the surface of the PFA tube coated with the PFA raw material to cool and solidify the coating of the PFA tube, thereby achieving a good PFA tube coating effect and making the PFA tube antistatic.
