Description

Technical Field

[0001] This invention relates to the field of corona technology, and in particular to a corona process for a dialysate filter housing. Background Technology

[0002] Dialysis fluid filters are common medical devices. The production process of dialysis fluid filters mainly includes cleaning, sealing, glue injection and centrifugation, membrane cutting, assembly, and sterilization. Among them, glue injection and centrifugation are used to fix the fiber membrane material inside the dialysis fluid filter and ensure its seal. This involves that the inner surface of the dialysis fluid filter shell must be firmly bonded to the glue.

[0003] Currently, the adhesion between the inner surface of the dialysate filter housing and the adhesive is not strong. After centrifugation and the application of pressure, the adhesive is easily detached, leading to defective products. Therefore, increasing the adhesion between the inner surface of the dialysate filter housing and the adhesive is an urgent problem to be solved. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a corona treatment process for the housing of a dialysate filter, which improves the adhesion between the inner surface of the dialysate filter housing and the adhesive, thereby improving product quality.

[0005] According to a first aspect of the present invention, a corona treatment process for a dialysate filter housing is applied to a corona treatment machine. The corona treatment machine includes a frame and two sets of corona treatment devices arranged side by side. Each corona treatment device includes two vertically opposite corona treatment modules that can be close to or far apart from each other. Each corona treatment module includes a loading mold and a negative electrode head. The loading mold is provided with a vertically extending receiving groove. A blocking step is provided in the receiving groove. A negative electrode ring is provided on the inner sidewall of the receiving groove. The negative electrode head passes vertically through the receiving groove and is coaxially arranged with the receiving groove. The negative electrode head is rotatable. The corona treatment process includes the following steps:

[0006] To install the product, insert the outer casing to be corona-electrode into the receiving groove of the lower loading mold. The outer casing abuts against the blocking step, and the lower negative electrode head enters the inner cavity of the outer casing. Then, lower the upper loading mold along with the corresponding negative electrode head so that the upper end of the outer casing is inserted into the corresponding receiving groove and abuts against the corresponding blocking step. At this time, the outer casing is clamped by the two loading molds, and the two opposite negative electrodes are inserted into the upper and lower inner cavities of the outer casing, respectively.

[0007] Open the ozone exhaust pipe. The frame is also equipped with an ozone exhaust pipe. The air inlet of the ozone exhaust pipe is set towards the loading mold. The number of ozone exhaust pipes corresponds one-to-one with the loading mold. Before the corona treatment starts, the ozone exhaust pipe needs to be opened to form a certain negative pressure area between the ozone exhaust pipe and the loading mold. The negative pressure device can suck away the ozone generated by the corona treatment through the ozone exhaust pipe.

[0008] The rotating corona discharge activates the negative electrode ring and drives the negative electrode head to rotate. At this time, a plasma region is generated between the negative electrode ring and the negative electrode head. This plasma region corona discharges the inner wall of the outer shell for a predetermined time, so that the corona discharge on the inner wall of the outer shell is uniform.

[0009] After the product is removed and the corona treatment is completed, the loading mold that is relatively high up, together with the corresponding negative electrode head, is lifted up and the product is removed manually.

[0010] Corona discharge test verification: Three batches of shells from non-continuous production were taken as samples. Each batch of samples contained more than 100 shells. The adhesion effect was tested 5 times using dyne reagent in each batch of production. The test determined that the voltage of the corona discharge machine was 30±2KV and the discharge time was 6s.

[0011] Mass production is carried out after corona testing and verification, repeating the steps from installing the product to removing the product.

[0012] Results verification: The casing after the mass production step was verified. Under the condition that the casing was not deformed, melted or charred, dyne reagent was applied to the corona part of the casing. After waiting for a predetermined time, it was observed whether the dyne reagent was evenly applied and whether the longitudinal width of the dyne reagent display band was greater than 15mm.

[0013] The corona treatment process for a dialysate filter housing according to an embodiment of the present invention has at least the following beneficial effects: The housing is loaded using two vertically arranged loading molds, and the receiving groove and the blocking step are provided to make the housing more stable during loading. The negative electrode head is driven to rotate instead of the housing itself rotating. The negative electrode head can perform corona treatment on the inner cavity of the housing, improving the adhesion between the predetermined part of the inner cavity and the adhesive, thus improving product quality. Furthermore, because the negative electrode head rotates, corona errors caused by housing rotation are avoided. When the housing rotates, end-face errors may occur during installation, resulting in circular runout. End-face errors refer to the warping of the housing's end face during installation. By controlling the relative... The upper loading mold moves vertically, which can both clamp the outer shell and guide and align it. Because it is vertically arranged, the combined action of the outer shell's gravity and the two opposing loading molds can align the outer shell's axis, preventing any misalignment between the outer shell's axis and the axes of the two opposing loading molds. The ozone exhaust pipe is opened before corona treatment, ensuring that the generated ozone is removed throughout the entire corona treatment process. Since the ozone exhaust pipe's intake is oriented towards the loading mold, precise ozone removal is achieved. Experiments are conducted on the corona-treated product to obtain parameters, facilitating subsequent mass production. Results are then verified on mass-produced products to ensure product quality upon delivery.

[0014] According to some embodiments of the present invention, the height of the blocking step is adjustable. The adjustable height of the blocking step allows the length of the inserted outer casing to be manually controlled, that is, the length of the negative electrode head extending into the inner cavity of the outer casing can be controlled, which facilitates corona treatment at a predetermined position and corona treatment for outer casings with different specifications, thereby improving the applicability of the loading mold and making it universal.

[0015] According to some embodiments of the present invention, the blocking step is vertically damped and slidably disposed within the loading mold, which allows the blocking step to be driven down by the outer casing during product installation, making operation more convenient. Of course, the receiving groove has a scale, and the operator can drive the blocking step down to a predetermined scale as needed. In addition, the loading mold is also provided with a recovery mechanism, which can drive the blocking step up.

[0016] According to some embodiments of the present invention, the loading mold is provided with a branch pipe slot, and the loading mold of each group of corona devices has one type of branch pipe slot. The branch pipe slot is used to receive the branch pipe of the shell. Different groups of corona devices correspond to different types of branch pipe slots. In this way, different types of dialysate filter shells can be corona processed on one machine, increasing the corona processing capacity of the whole machine and improving production efficiency.

[0017] According to some embodiments of the present invention, the method further includes the step of installing a negative electrode head body, the negative electrode head including a rotating rod and a negative electrode head body, the negative electrode head body being detachably connected to the rotating rod, the rotating rod being drivenly connected to a power component, the negative electrode head body being accommodated in the receiving groove, the negative electrode head body being used to extend into the inner cavity of the housing, and prior to the step of installing the product, the negative electrode head body adapted to the inner cavity of the housing is installed as required, and different negative electrode head bodies are selected according to different housings in order to achieve a better corona discharge effect.

[0018] According to some embodiments of the present invention, the negative electrode head body includes a trapezoidal body, a radial body, and a disc-shaped body.

[0019] According to some embodiments of the present invention, in the step of installing the product, the upper loading mold is mounted on a bracket, the bracket is slidably mounted on the frame along a guide rail, and the bracket is connected to a cylinder for driving the upper loading mold to rise and fall. The structure is simple and the operation is convenient.

[0020] According to some embodiments of the present invention, in the step of opening the ozone exhaust pipe, the frame includes a protective shell and a protective door. The protective shell covers the corona discharge device, and the protective door is disposed on the protective shell. The frame is also provided with two interlocking switches. Only when the two interlocking switches are pressed simultaneously can a plasma region be generated between the negative electrode head and the negative electrode ring. After the corona discharge is completed, the ozone exhaust pipe draws ozone for 10 to 15 seconds before opening the protective door to fully discharge the ozone and ensure operational safety.

[0021] According to some embodiments of the present invention, the loading mold is made of plastic, which facilitates manufacturing and replacement.

[0022] According to some embodiments of the present invention, the upper opening of the receiving groove is provided with a chamfer to facilitate the insertion of the outer casing.

[0040] Reference Figures 1 to 8 A corona treatment process for a dialysate filter housing is disclosed, applied to a corona treatment machine. The corona treatment machine includes a frame 100 and two sets of corona treatment devices arranged side by side. Each corona treatment device includes two vertically opposite corona treatment modules 200, which can be positioned close to or far apart. Each corona treatment module 200 includes a loading mold 210 and a negative electrode head 220. The loading mold 210 has a vertically extending receiving groove 211 with a blocking step 212 inside. A negative electrode ring 213 is provided on the inner sidewall of the receiving groove 211. The negative electrode head 220 passes vertically through the receiving groove 211 and is coaxially arranged with the receiving groove 211. The negative electrode head 220 is rotatable. The corona treatment process includes the following steps:

[0041] To install the product, insert the outer casing to be corona-electrode into the receiving groove 211 of the lower loading mold 210. The outer casing abuts against the blocking step 212, and the lower negative electrode 220 enters the inner cavity of the outer casing. Then, lower the upper loading mold 210 together with the corresponding negative electrode 220, so that the upper end of the outer casing is inserted into the corresponding receiving groove 211 and abuts against the corresponding blocking step 212. At this time, the outer casing is clamped by the two loading molds 210, and the two opposite negative electrodes 220 are inserted into the upper and lower inner cavities of the outer casing, respectively.

[0042] Open the ozone exhaust pipe. There is also an ozone exhaust pipe 110 inside the frame 100. The air inlet of the ozone exhaust pipe 110 is set towards the loading mold 210. The number of ozone exhaust pipes 110 corresponds to the number of loading molds 210. Before the corona treatment starts, the ozone exhaust pipe 110 needs to be opened to form a certain negative pressure area between the ozone exhaust pipe 110 and the loading mold 210. The negative pressure device can suck away the ozone generated by the corona treatment through the ozone exhaust pipe 110.

[0043] The rotating corona discharge activates the negative electrode ring 213 and drives the negative electrode head 220 to rotate. At this time, a plasma region is generated between the negative electrode ring 213 and the negative electrode head 220. This plasma region corona discharges the inner wall of the outer shell for a predetermined time, so that the corona discharge on the inner wall of the outer shell is uniform.

[0044] After the product is removed and the corona treatment is completed, the upper loading mold 210 and the corresponding negative electrode head 220 are raised together, and the product is removed manually.

[0045] Corona discharge test verification: Three batches of shells from non-continuous production were taken as samples. Each batch of samples contained more than 100 shells. The adhesion effect was tested 5 times using dyne reagent in each batch of production. The test determined that the voltage of the corona discharge machine was 30±2KV and the discharge time was 6s.

[0046] Mass production begins after corona testing and verification, repeating the steps from product installation to product removal.

[0047] Results verification: The casing after the mass production step was verified. Under the condition that the casing was not deformed, melted or charred, dyne reagent was applied to the corona part of the casing. After waiting for a predetermined time, it was observed whether the dyne reagent was evenly applied and whether the longitudinal width of the dyne reagent display band was greater than 15mm.

[0048] Two vertically arranged loading molds 210 are used to load the outer casing. A receiving groove 211 and a blocking step 212 are provided to ensure stable loading of the outer casing. The negative electrode head 220 is driven to rotate instead of the outer casing itself. The negative electrode head 220 can perform corona treatment on the inner cavity of the outer casing, improving the adhesion between the predetermined part of the outer casing and the adhesive, thus improving product quality. Furthermore, because the negative electrode head 220 rotates, corona errors caused by outer casing rotation are avoided. When the outer casing rotates, end-face errors can occur during installation, resulting in circular runout, i.e., the end face of the outer casing tilting during installation. By controlling the vertical movement of the relatively upper loading mold 210, [the following is possible:] ... This allows for the clamping of the outer casing and also provides guidance and alignment. Because it is vertically oriented, the combined effect of the casing's gravity and the two opposing loading molds 210 ensures the casing's axis is aligned, preventing any misalignment between the casing's axis and the two loading molds 210. Before corona treatment, the ozone exhaust pipe 110 is opened, ensuring that the generated ozone is removed throughout the entire corona treatment process. Furthermore, the ozone exhaust pipe 110's inlet faces the loading mold 210, enabling precise ozone removal. Experiments are conducted on the corona-treated product to obtain parameters, facilitating subsequent mass production. Results are then verified on mass-produced products to guarantee product quality upon delivery.

[0049] In some embodiments, the height of the blocking step 212 is adjustable. The adjustable height of the blocking step 212 allows the length of the inserted outer casing to be manually controlled, that is, the length of the negative electrode head 220 extending into the inner cavity of the outer casing can be controlled, which facilitates corona treatment at a predetermined position and corona treatment for outer casings with different specifications, thereby improving the applicability of the loading mold 210 and making it universal.

[0050] In some embodiments, the blocking step 212 is vertically damped and slidably disposed within the loading mold 210. This allows the blocking step 212 to be driven downwards via the outer casing during product installation, making operation more convenient. The receiving groove 211 has graduations, allowing the operator to drive the blocking step 212 downwards to a predetermined graduation as needed. Furthermore, the loading mold 210 is also equipped with a recovery mechanism that can drive the blocking step 212 upwards. It is understood that the recovery mechanism can be a rack and pinion mechanism, with the rack connected to the blocking step 212. The gear is rotatably connected to the outer wall of the loading mold 210. The gear and rack mesh. When the gear is turned, the rack can drive the blocking step 212 to rise and fall, and naturally restore the position of the blocking step 212. The restoration mechanism can also be a lever. One end of the lever is connected to the blocking step 212, and the other end of the lever protrudes from the outer wall of the loading mold 210. The other end of the lever can slide vertically on the outer wall of the loading mold 210. The specific solution for sliding vertically is to open a vertical slot on the outer wall of the loading mold 210, so as to avoid the lever.

[0051] Reference Figure 2 and Figure 5 The loading mold 210 is provided with a branch pipe slot 214. Each loading mold 210 of the corona device has a type of branch pipe slot 214. The branch pipe slot 214 is used to receive the branch pipe of the shell. Different groups of corona devices correspond to different types of branch pipe slots 214. In this way, different types of dialysate filter shells can be corona processed on one machine, increasing the corona processing capacity of the whole machine and improving production efficiency. It can be understood that the shell of the dialysate filter is cylindrical in shape, and branch pipes are provided on its peripheral wall. The shape of the branch pipes is not uniform and has different specifications. Therefore, in order to ensure the stability of the shell inserted into the receiving groove 211, or to make the axis of the receiving groove 211 basically collinear with the axis of the shell, it is necessary to set the branch pipe slot 214 as a clearance position.

[0052] In some embodiments, the method further includes the step of installing a negative electrode head body 222. The negative electrode head 220 includes a rotating rod 221 and a negative electrode head body 222. The negative electrode head body 222 is detachably connected to the rotating rod 221. The rotating rod 221 is drivenly connected to a power component. The negative electrode head body 222 is housed in a receiving groove 211. The negative electrode head body 222 is used to extend into the inner cavity of the housing. Before the product installation step, a negative electrode head body 222 adapted to the inner cavity of the housing is installed according to requirements. Different negative electrode head bodies 222 are selected according to different housings in order to achieve a better corona effect. It is understood that different dialysate filter housings may have different inner diameters and inner cavity cross-sectional shapes. Applying different negative electrode head bodies 222 can better generate a corona effect on the inner cavity of different dialysate filter housings.

[0053] Reference Figures 6 to 8 The negative electrode head body 222 includes a trapezoidal body, a radial body, and a disc-shaped body. It should be noted that it includes, but is not limited to, these three types.

[0054] In some embodiments, during the product installation step, the upper loading mold 210 is mounted on the bracket 120. The bracket 120 is slidably mounted on the frame 100 along the vertical direction via the guide rail 130. The bracket 120 is connected to a cylinder 140, which is used to drive the upper loading mold 210 to rise and fall. The structure is simple and the operation is convenient.

[0055] In some embodiments, during the step of opening the ozone exhaust duct, the frame 100 includes a protective housing 150 and a protective door 160. The protective housing 150 is covered with a corona discharge device, and the protective door 160 is disposed on the protective housing 150. The frame 100 is also provided with two interlocking switches 170. Only when the two interlocking switches 170 are pressed simultaneously can a plasma region be generated between the negative electrode head 220 and the negative electrode ring 213. After the corona discharge is completed, the ozone exhaust duct 110 draws ozone for 10 to 15 seconds before opening the protective door 160 to fully discharge the ozone and ensure operational safety. It is understood that the interlocking switch 170 is a common industrial interlocking switch used to ensure safety control.

[0056] In some embodiments, the loading mold 210 is made of plastic for ease of manufacture and replacement. It is understood that the loading mold 210 can be obtained by injection molding.

[0057] In some embodiments, the upper opening of the receiving groove 211 is chamfered to facilitate the insertion of the housing.

[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
