Description

Technical Field

[0001] This utility model belongs to the field of membrane separation equipment manufacturing technology, and more specifically, relates to a column-type membrane end cap bonding device. Background Technology

[0002] A column-type membrane module is a precision filtration device composed of multiple components, including membrane fibers, adhesives, membrane tubes, end caps, end fittings, sealing rings, and clamps. In this module, the bonding of the membrane tubes to the end caps forms the main structure of the membrane housing. After the end caps and end fittings are first bonded and fixed, they are then connected to the main structure of the membrane housing via clamps and sealing rings, forming a reliable sealed connection and ultimately achieving overall sealing and fixation of the membrane housing.

[0003] The manufacturing process of column-type membrane modules involves seven key steps: end cap bonding, membrane shell bonding, casting, cutting, assembly, inspection, and packaging. Particularly crucial is the end cap bonding step, where operators must precisely align the end cap with the pipe fitting interface. This process typically requires two operators working together: one to hold the end cap in place, and the other to use a rubber mallet to tap the pipe fitting interface into the end cap until the predetermined bonding limit is reached. This step requires multiple precise taps, and the operator must immediately measure the dimensions of the bonding area after reaching the limit to ensure dimensional accuracy.

[0004] To promote initial curing of the adhesive and prevent pipe joint detachment, a certain amount of pressing time is required after bonding. However, due to the short initial curing time of the adhesive, minor errors during operation, such as improper tapping force or inaccurate positioning, can lead to dimensional deviations in the end caps, thus affecting the overall dimensional accuracy of the membrane module. To address this challenge, this invention proposes an innovative column-type membrane end cap bonding device, aiming to improve the accuracy and efficiency of the bonding process and ensure the processing quality and successful completion of the membrane module.

[0019] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0020] Example

[0021] like Figure 1 As shown, this embodiment provides a column-type membrane end cap bonding device, including: Clamping assembly 1 is fixedly installed and is used to clamp end cap 2; The first cylinder 3 has a first pressing connector 4 connected to its telescopic end. The position of the first pressing connector 4 corresponds to the position of the upper pipe fitting interface 21. The telescopic direction of the first cylinder 3 is the same as the pressing direction of the upper pipe fitting interface 21. The second cylinder 5 has a second pressing connector 6 connected to its telescopic end. The position of the second pressing connector 6 corresponds to the position of the side pipe interface 22. The telescopic direction of the second cylinder 5 is the same as the pressing direction of the side pipe interface 22.

[0022] In use, place the end cap 2 and the pipe fitting interface on the operating table. After applying adhesive to the predetermined bonding positions, gently push the upper pipe fitting interface 21 and the lower pipe fitting interface into the corresponding end cap 2 interfaces to complete the initial assembly. Then, place the initially assembled end cap 2 into the clamping assembly 1, adjust the angle of the end cap 2 so that the side pipe fitting interface is aligned with the second pressing connector 6, and operate the clamping assembly 1 to fix the position of the end cap 2. Next, activate the first cylinder 3 to extend the first pressing connector 4, pushing the upper pipe fitting interface 21 into the upper interface of the end cap 2. Subsequently, activate the second cylinder 5 to extend the second pressing connector, pushing the side pipe fitting interface 22 into the side interface of the end cap 2. Depending on the characteristics of the adhesive used, maintain a stable pressure for a period of time, then activate the second cylinder 5 to retract the second pressing connector 6, and then activate the first cylinder 3 to retract the first pressing connector 4. Finally, operate the clamping assembly 1 to release the end cap 2, remove the bonded end cap 2, and complete the bonding. It should be noted that the clamping component 1 can be implemented using existing technology, such as a gripper structure driven by a bidirectional screw. This utility model does not limit the specific form of the clamping component 1, as long as it can fix the end cap 2.

[0023] Specifically, clamping component 1 is used to fix end cap 2, eliminating the need for manual support during the bonding process. First cylinder 3 is used to press the upper pipe fitting interface 21, and second cylinder 5 is used to press the side pipe fitting interface 22. This enables precise bonding and pressure-holding positioning in a single operation, replacing the need for repeated manual tapping of the pipe fitting interfaces. This reduces the number of operators, lowers operational risks, and reduces the risk of inconsistent bonding dimensions, effectively improving the bonding quality of the product.

[0024] Optionally, the column-type membrane end cap bonding device further includes: The first column 7 is fixedly installed. The first cylinder 3 is connected to the first column 7 through a first sliding locking structure. The first cylinder 3 can slide or lock through the first sliding locking structure. The sliding direction of the first sliding locking structure is the same as the extension and retraction direction of the first cylinder 3. The second column 8 is fixedly installed. The second cylinder 5 is connected to the second column 8 through a second sliding locking structure. The second cylinder 5 can slide or lock through the second sliding locking structure. The sliding direction of the second sliding locking structure is perpendicular to the extension and retraction direction of the second cylinder 5.

[0025] Specifically, the first cylinder 3 is connected to the first column 7 through the first sliding locking structure, and the second cylinder 5 is connected to the second column 8 through the second sliding locking structure, so as to realize the position adjustment of the first cylinder 3 and the second cylinder 5, which is compatible with end caps 2 and pipes of different sizes, and avoids the defect of traditional devices that require the replacement of the entire set of fixtures due to specification differences.

[0026] Optionally, the first sliding locking structure includes a first slide rail 9, a first slider 10 and a first driving component. The first slider 10 is slidably connected to the first slide rail 9, the first slider 10 is fixedly connected to the first cylinder 3, the first driving component is connected to the first slider 10, and the first driving component is self-locking. The second sliding locking structure includes a second slide rail 11, a second slider 12, and a second driving component. The second slider 12 is slidably connected to the second slide rail 11 and is fixedly connected to the second cylinder 5. The second driving component is connected to the second slider 12 and is capable of self-locking.

[0027] Specifically, both the first sliding locking structure and the second sliding locking structure have a self-locking function, such as a servo motor and a worm gear, to ensure that the first cylinder 3 and the second cylinder 5 have no displacement after positioning, thus avoiding displacement caused by reaction force during the pressing process.

[0028] Optionally, the column-type membrane end cap bonding device further includes: The operating platform 13, clamping component 1, first column 7 and second column 8 are all fixedly installed on the upper surface of the operating platform 13.

[0029] Furthermore, the column-type membrane end cap bonding device also includes: Four support legs 14 are fixedly connected to the lower surface of the operating platform 13, and the four support legs 14 together support the operating platform 13.

[0030] Specifically, the four support legs 14 can support the operating table on the one hand, and form an open storage space on the other hand, providing space for temporary storage of materials.

[0031] Optionally, the first pressing connector 4 is detachably connected to the first cylinder 3, and there are multiple first pressing connectors 4, each of which is set to a different size; The second pressing connector 6 is detachably connected to the second cylinder 5. There are multiple second pressing connectors 6, and the multiple second pressing connectors 6 are respectively set to different sizes.

[0032] Specifically, both the first press connector 4 and the second press connector 6 adopt a detachable structure and are available in various sizes, allowing for quick switching via standardized interfaces. The first press connector 4 and the second press connector 6 can be replaced with different sizes depending on the diameter of the upper pipe fitting interface 21 and the side pipe fitting interface 22.

[0033] Optionally, the column-type membrane end cap bonding device further includes: The first button 15 is electrically connected to the first sliding locking structure and is used to control the action of the first sliding locking structure.

The third button 17 is electrically connected to the first cylinder 3 and is used to control the action of the first cylinder 3. The fourth button 18 is electrically connected to the second cylinder 5 and is used to control the action of the second cylinder 5.

[0034] Specifically, the operation of the first sliding locking structure, the second sliding locking structure, the first cylinder 3 and the second cylinder 5 can be precisely controlled by independent buttons to prevent accidental operation.

[0035] Optionally, the column-type membrane end cap bonding device further includes: The first pressure gauge 19 is connected to the first cylinder 3 and is used to display the pressure of the first cylinder 3; The second pressure gauge 20 is connected to the second cylinder 5 and is used to display the pressure of the second cylinder 5.

[0036] Specifically, an independent pressure gauge displays the pressure of the first cylinder 3 and the second cylinder 5 in real time, preventing overpressure from causing deformation of the end cap 2 and improving the bonding quality.

[0037] The method of using the column-type membrane end cap bonding device in this embodiment is as follows: First, by using the first button 15 on the activation device, the vertical position of the first slider 10 on the first positioning post is precisely adjusted. This adjustment is based on the desired height dimension after the end cap 2 and the upper pipe fitting interface 21 are bonded together, thereby setting a predetermined distance between the first pressing joint 4 on the first cylinder 3 and the table surface of the clamping assembly 1.

[0038] Next, using the second button 16, the vertical position of the second slider 12 on the second positioning post is adjusted. This step determines the predetermined distance between the second pressing joint 6 on the second cylinder 5 and the clamping assembly 1 based on the side dimensions after the end cap 2 and the side tube interface 22 are bonded together.

[0039] Subsequently, it was confirmed whether the pressing pressure indicated by the first pressure gauge 19 and the second pressure gauge 20 met the process requirements.

[0040] During operation, place the end cap 2, upper pipe fitting interface 21, and side pipe fitting interface 22 on the operating table. After applying adhesive to the predetermined bonding positions, gently push the upper pipe fitting interface 21 and side pipe fitting interface 22 into the end cap 2 interface to complete the initial assembly. Then, place the initially assembled end cap 2 on the clamping assembly 1 table, ensuring that the side pipe fitting interface 22 is aligned with the second press connector 6. Operate the clamping assembly 1 to fix the position of the end cap 2.

[0041] Next, press the third button 17 to push the upper pipe fitting interface 21 into the upper interface of the end cap 2 using the first pressing connector. Then, press the fourth button 18 to push the side pipe fitting interface 22 into the side interface of the end cap 2 using the second pressing connector 6. After maintaining stable pressure for a period of time, depending on the properties of the adhesive used, first press the fourth button 18 to retract the second pressing connector 6, then press the third button 17 to retract the first pressing connector 4. Finally, release the clamping assembly 1 and remove the bonded end cap 2, completing the bonding of the end cap 2.

[0042] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
