Description

[0001] This application claims priority to Chinese Patent Application No. 202210050292.4, filed on January 17, 2022, entitled "A Membrane Curing Assembly Device and Filter Manufacturing Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0003] Currently, the filtration and separation of insoluble substances in liquids typically employ methods such as centrifugation, natural sedimentation, and membrane filtration. Compared to other methods, membrane filtration is simple, rapid, and provides precise separation, and therefore has been widely adopted.

[0004] Membrane filtration cartridges are typically in flat or rolled form, primarily for ease of assembly and manufacturing of the membrane and modules. However, some applications require specialized filter cartridge structures to reduce membrane clogging and facilitate the enrichment of insoluble substances, such as conical filters and tetrahedral filters. These specialized filters require membranes cut to the desired shape and then manually bonded together. The bonded membrane bags are then manually blown into conical or tetrahedral shapes before being assembled with supports and retaining rings. This process is labor-intensive and time-consuming, and manual assembly suffers from issues such as inconsistent quality, high scrap rates, and excessively high production costs.

Detailed Implementation

[0076] The following will refer to the appendices in the embodiments of the present invention. Figures 1-11 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0077] In the description of this invention, it should be understood that the terms "upper," "lower," "top surface," "bottom surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0078] like Figure 1 As shown, the first aspect of this invention provides a membrane curing and assembly apparatus 100, which enables automated production of filter membrane bags, reducing manual labor intensity and improving production efficiency. It is understood that the membrane curing and assembly apparatus 100 provided by this invention can not only prepare irregularly shaped membrane bags, such as membrane bags for conical filters 200 or tetrahedral filters 200, but also membrane bags with regular shapes, such as membrane bags for flat-plate filters 200. It is also understood that the membrane curing and assembly apparatus 100 provided by this invention is not limited to the preparation of membrane bags, but can also be used for the preparation of other flexible materials that need to be folded, bonded, and unfolded to a certain shape.

[0079] Taking the manufacture of a conical filter 200 as an example, such as Figures 2-4 As shown.

[0080] Specifically, the membrane curing assembly device 100 includes a membrane positioning component 101, a push rod component 102, a curing component, and a negative pressure component 103.

[0081] The membrane positioning assembly 101 is used to position the membrane sheet of a preset shape to be cured. It should be noted that the membrane sheet here refers to a membrane sheet with a filtering function, and the preset shape refers to the shape of the membrane bag 201 after it is unfolded, which is specifically determined according to the required membrane bag 201 to be prepared. Taking the membrane bag 201 to be formed as an example of a conical filter 200, the corresponding preset shape membrane sheet is as follows: Figure 11 As shown.

[0082] The push rod assembly 102 is used to fold the membrane positioned on the membrane positioning assembly 101 into a folded filter membrane. Furthermore, the present invention discloses that the push rod assembly 102 is folded along the symmetrical center line of the membrane, so that the membrane is folded into an edge-aligned folded filter membrane.

[0083] The curing component is used to cure the edges of the folded filter membrane that are to be cured. It should be noted that the structure of the curing component is not limited. As long as the structure can cure and connect the edges of the folded filter membrane to be cured, it is within the scope of protection of this invention.

[0084] The negative pressure assembly 103 is provided with a negative pressure chamber 103a-1 that fits the shape of the molded membrane bag 201 to be manufactured. The negative pressure chamber 103a-1 is used to accommodate the cured folded membrane bag 201a pushed by the pusher assembly 102, and under negative pressure, the folded membrane bag 201a unfolds into the molded membrane bag 201. It should be noted that the membrane bag here refers to a membrane bag with a certain spatial shape that meets the usage requirements of the filter 200.

[0085] The membrane curing assembly apparatus 100 provided by this invention, in use, involves placing a membrane sheet with a preset shape onto a membrane positioning assembly 101; then, folding the membrane sheet into a folded filter membrane using a pusher assembly 102; next, a curing unit cures the folded edges of the filter membrane together to form a folded membrane bag 201a; then, the cured folded membrane bag 201a is pushed into a negative pressure chamber 103a-1 on a negative pressure assembly 103 using the pusher assembly 102; finally, the negative pressure assembly 103 activates to draw the folded membrane bag 201a into a position that adheres to the inner wall of the negative pressure chamber 103a-1, thus opening the folded membrane bag 201a into a formed membrane bag 201. The membrane curing assembly apparatus 100 provided by this invention achieves automated preparation of formed membrane bags 201 of the desired shape, reducing manual labor intensity and improving production efficiency.

[0086] In some embodiments, such as Figure 5 As shown, the membrane positioning assembly 101 includes a membrane positioning stage 101a, on which a slit 101a-1 is provided, and the push rod assembly 102 can press down and fold the membrane along the slit 101a-1.

[0087] Understandably, the shape of the membrane positioning stage 101a is not limited and can be any shape. In order to reduce the overall weight of the membrane positioning stage 101a, it can be set as a hollow stage. Of course, in order to improve the strength of the membrane positioning stage 101a, it can also be set as a solid stage.

[0088] The membrane positioning assembly 101 is not limited to the structure described above, but can also be other structures. For example, the membrane positioning assembly 101 includes a support portion and a rotatable portion, which are rotatably connected, specifically through a hinge or the like. In the initial state, the support portion and the rotatable portion are in an open state, and at this time, the support portion and the rotatable portion are flush. The membrane is positioned on the support portion and the rotatable portion, and the symmetry line (i.e., the fold line) of the membrane is located on the hinge line of the support portion and the rotatable portion. The push rod assembly 102 presses against the symmetry line of the membrane. Then, the rotatable portion rotates, causing the portion of the membrane located on the rotatable portion to rotate, and thus presses against the portion of the membrane located on the support portion. Of course, the rotatable portion is provided with a groove that can accommodate the push rod assembly 102 pressed against the symmetry line of the membrane. The folded membrane can be welded by a welding head, or it can be glued together after folding by applying glue to the edges of the membrane beforehand.

[0089] Furthermore, in order to facilitate the positioning of the membrane, the present invention discloses that the membrane positioning stage 101a is provided with a positioning groove 101a-2 for positioning the membrane, and the slit 101a-1 is opened in the positioning groove 101a-2, and the bottom end of the positioning groove 101a-2 is provided with a plurality of first negative pressure holes for adsorbing the membrane.

[0090] Understandably, the shape of the positioning groove 101a-2 is at least partially adapted to the shape of the diaphragm in order to position the diaphragm.

[0091] It should also be noted that the positioning groove 101a-2 can be a groove formed on the membrane positioning platform 101a, or it can be formed by a wall set on the membrane positioning platform 101a, etc.

[0092] To facilitate folding of the film, the present invention discloses that the slit 101a-1 is opened on the symmetrical line of the positioning groove 101a-2.

[0093] Furthermore, this invention discloses a limiting part at the bottom end of the slit 101a-1 to limit the downward pressing distance of the diaphragm. Specifically, the limiting part can be a limiting plate integrally formed with the membrane positioning stage 101a, or it can be a limiting plate separately welded or detachably connected to the bottom end of the slit 101a-1, etc. Any structure that can limit the downward pressing distance of the diaphragm falls within the protection scope of this invention.

[0094] To facilitate the guidance of the push rod assembly 102, the present invention discloses that the length of the limiting plate is equal to the length of the slit 101a-1, or extends out of the end of the slit 101a-1 facing the negative pressure assembly 103.

[0095] To prevent the membrane from moving and improve the positioning accuracy of the membrane, the present invention discloses that the bottom end of the positioning groove 101a-2 is provided with a plurality of negative pressure holes for adsorbing the membrane, so as to firmly adsorb the membrane in the positioning groove 101a-2.

[0096] In some embodiments, the present invention discloses that along the length direction of the slit 101a-1, the push rod assembly 102 and the negative pressure assembly 103 are respectively located at both ends of the membrane positioning assembly 101, so that the push rod assembly 102 pushes the cured folded membrane bag 201a into the negative pressure chamber 103a-1 of the negative pressure assembly 103 after the membrane is folded and after the curing member has cured the folded filter membrane. Figure 6 As shown.

[0097] In some embodiments, the cured component includes a welding head disposed within the slit 101a-1. Specifically, the welding head is a thermomelting welding head, an ultrasonic welding head, or a high-frequency welding head.

[0098] It should be noted that the curing part is not limited to the welding head, but can also be the glue applicator, etc. The glue applicator is completed by pre-applying adhesive to the edge of the film to be cured. Specifically, the adhesive can be a two-component curing adhesive, a UV curing adhesive, a pressure-sensitive adhesive, etc.

[0099] In some embodiments, the push rod assembly 102 includes a push rod 102a and a drive device 102b. The drive device 102b is connected to the push rod 102a in a transmission manner. The drive device 102b is used to drive the push rod 102a to press down the diaphragm and push the cured folded film bag 201a into the negative pressure chamber 103a-1.

[0100] Furthermore, the present invention discloses that the push rod assembly 102 further includes a horizontal slide rail 402 and a vertical slide rail 402. The vertical slide rail 402 is slidably mounted on the horizontal slide rail 402 along the horizontal direction, and the push rod 102a is slidably mounted on the vertical slide rail 402 along the vertical direction; or, the horizontal slide rail 402 is slidably mounted on the vertical slide rail 402 along the vertical direction, and the push rod 102a is slidably mounted on the horizontal slide rail 402 along the horizontal direction.

[0101] The drive device 102b can be a screw and nut structure, a cylinder, a hydraulic cylinder, or an electric push rod, etc. Taking the drive device 102b as an electric push rod, the vertical slide rail 402 can be slidably installed on the horizontal slide rail 402 along the horizontal direction, and the push rod 102a can be slidably installed on the vertical slide rail 402 along the vertical direction as an example, one electric push rod drives the vertical guide rail to slide along the horizontal guide rail, and another electric push rod pushes the push rod 102a to slide along the vertical guide rail.

[0102] To facilitate the opening of the cured folded film bag 201a, the present invention discloses that the end of the push rod 102a used to push the folded film bag 201a is provided with a sphere or hemisphere, etc.

[0103] To facilitate the opening of the folded film bag 201a, the present invention discloses a blowing device provided in the opening direction of the folded film bag 201a, which blows air onto the folded film bag 201a. Specifically, the blowing device may be an air blowing pipe or the like that blows air onto the opening direction of the folded film bag 201a.

[0104] In some embodiments, the negative pressure assembly 103 includes a receiving portion 103a, and a negative pressure cavity 103a-1 is formed on the receiving portion 103a. Specifically, the receiving portion 103a is provided with a plurality of second negative pressure holes communicating with the negative pressure cavity 103a-1.

[0105] In some embodiments, the negative pressure assembly 103 further includes a rotary power device 103b, which is tractively connected to the receiving portion 103a and is used to drive the receiving portion 103a to rotate so that the inlet of the negative pressure chamber 103a-1 faces the direction in which the push rod assembly 102 pushes the folded membrane bag 201a in. The rotary power device 103b can also, after the folded membrane bag 201a enters and opens the negative pressure chamber 103a-1, drive the receiving portion 103a to rotate to its initial state (i.e., the inlet of the negative pressure chamber 103a-1 faces upwards, facilitating the installation of the filter bracket 203 into the formed membrane bag 201), such as... Figure 7 As shown.

[0106] Specifically, the receiving part 103a is provided with rotating shafts at both ends, and the rotating shafts are rotatably mounted on the support frame. The rotating shafts are driven by a rotary cylinder or motor to achieve rotation. It should be noted that in order to adjust the rotation speed of the rotating shaft, the speed can also be adjusted by a gear set, a conveyor belt or a sprocket chain between the motor and the rotating shaft.

[0107] like Figure 8 and Figure 9 As shown, a second aspect of the present invention provides a filter manufacturing apparatus 1000, including a robot arm 700 and a membrane curing assembly apparatus 100 as described in any of the above embodiments.

[0108] The negative pressure chamber 103a-1 is provided with a receiving groove for accommodating the retaining ring 202. The retaining ring 202 is used to hold the opened molded membrane bag 201. The robot arm 700 is used to grab the retaining ring 202 to the receiving groove, and to grab the filter bracket 203 to assemble into the molded membrane bag 201 to support the molded membrane bag 201. It is also used to grab the assembled filter 200 into the container to be placed.

[0109] Specifically, the items to be placed are trays, etc.

[0110] The filter manufacturing equipment 1000 provided by this invention involves a robotic arm 700 grasping a retaining ring 202 and placing it in a receiving groove. Next, a membrane bag with the desired shape and open shape is formed by a membrane curing assembly device 100, with the retaining ring 202 secured to the outside of the membrane bag. Then, the robotic arm 700 grasps a filter support 203 and assembles it into the membrane bag to support it. The filter support 203, membrane bag, and retaining ring 202 are assembled together to form a filter 200. Finally, the robotic arm 700 grasps the assembled filter 200 and places it into a container. This invention achieves automated assembly of the filter 200, avoiding manual assembly, reducing labor intensity, and improving the production efficiency of the filter 200.

[0111] In some embodiments, the filter manufacturing apparatus 1000 further includes a membrane supply device 300 for supplying membranes of a preset shape, and a robot arm 700 for gripping the membranes onto the membrane positioning assembly 101 of the membrane curing assembly apparatus 100.

[0112] Furthermore, such as Figure 10 As shown, the present invention specifically discloses a film supply device 300 including an unwinding assembly 301, a winding assembly 302, and a cutting component 303.

[0113] The unwinding assembly 301 is used to unwind the film roll that has been set into a roll. Specifically, the unwinding assembly 301 includes an unwinding shaft and an unwinding motor. The film roll is wound on the unwinding shaft, the unwinding motor is connected to the unwinding shaft for transmission, and the unwinding shaft is rotatably mounted on the unwinding bracket.

[0114] The winding assembly 302 is used for winding. Specifically, the winding assembly 302 includes a winding shaft and a winding motor, and is used to wind up the cut film. The cut film is as follows: Figure 11 As shown. The cut film is wound onto a take-up shaft, which is connected to a take-up motor. The take-up shaft is rotatably mounted on a take-up bracket.

[0115] Specifically, both the winding motor and the unwinding motor are stepper motors, used for step-by-step unwinding and step-by-step winding.

[0116] The cutter 303 is used to cut a film sheet of a preset shape from the film between the unwinding assembly 301 and the winding assembly 302. Understandably, the cutter 303 can be any device capable of cutting the film sheet, such as a laser cutting head or a cutting blade.

[0117] Taking the cutting part 303 as an example of a laser cutting head, the laser cutting head can slide along the X, Y, and Z directions in space to achieve the cutting of a film with a preset shape.

[0118] Furthermore, the present invention discloses that the film supply device 300 also includes a tension roller 304 and a support platform 305. The tension roller 304 is used to flatten and tension the film between the unwinding assembly 301 and the winding assembly 302 to the support platform 305. The cutting assembly drops the film of the preset shape onto the support platform 305. The robot arm 700 picks up the film and places it onto the film positioning assembly 101 of the film curing assembly device 100.

[0119] In some embodiments, the filter manufacturing apparatus 1000 further includes a retaining ring supply device 400 for supplying retaining rings 202.

[0120] Furthermore, the present invention discloses a retaining ring supply device 400 including a retaining ring holding component 401, a slide rail 402, and a pushing power component.

[0121] The retaining ring holder 401 contains multiple retaining rings 202 stacked together. The slide rail 402 is laid below the retaining ring holder 401. The ratio of the distance between the top of the slide rail 402 and the bottom of the retaining ring holder 401 to the thickness of the retaining ring 202 is greater than or equal to 1 and less than 2. That is to say, the gap between the slide rail 402 and the retaining ring holder 401 is greater than or equal to the thickness of one retaining ring 202 and less than the thickness of two retaining rings 202.

[0122] The pushing power component is used to push the retaining ring 202, which has fallen into the retaining ring holder 401 and is on the slide rail 402, out from under the retaining ring holder 401.

[0123] Specifically, vertical baffles are provided on the outer edges of both sides of the slide rail 402 to prevent the retaining ring 202 from slipping off the sides of the slide rail 402 during the sliding process.

[0124] In order to facilitate the alignment of the retaining ring 202 under the push of the material pushing power component, vertical blocking plates on both sides of the slide rail 402 can be set to tilt towards each other along the direction away from the retaining ring holding component 401, so as to facilitate the alignment of the retaining ring 202.

[0125] Specifically, the pushing power component is a cylinder, hydraulic cylinder, or electric push rod 102a, etc., and an arc-shaped pushing block that fits a part of the outer wall of the retaining ring 202 is provided at the driving end.

[0126] Furthermore, the slide rail 402 is provided with a retaining ring limiting part 402a for positioning the retaining ring 202 pushed by the pushing power component. Specifically, the side wall of the retaining ring limiting part 402a that limits the retaining ring 202 is an arc-shaped wall that matches the shape of the outer wall of the retaining ring 202.

[0127] In some embodiments, the filter manufacturing equipment 1000 further includes a base frame 500, and a membrane curing assembly device 100, a robot arm 700, a retainer ring supply device 400, and a membrane sheet supply device 300 are all mounted on the base frame 500.

[0128] Understandably, the base frame 500 includes a profile frame and a support platform 305 mounted on the profile frame. The membrane curing assembly device 100, the robot arm 700, the retaining ring supply device 400, and the membrane supply device 300 are all mounted on the support platform 305.

[0129] It should be noted that a welding frame can also be used instead of a profile frame, as long as the structure can support the support platform 305, it is within the scope of protection of this invention.

[0130] In some embodiments, the filter manufacturing equipment 1000 further includes a support tray 600, which is provided with a plurality of slots for holding filter supports 203, and a robot arm 700 is able to pick up the filter supports 203 from the support tray 600 and assemble them into the membrane bag.

[0131] Specifically, the support tray 600 is mounted on the support platform 305.

[0132] In some embodiments, the robotic arm 700 is provided with a gripper, a suction cup and an adhesive applicator, and the gripper is used to grasp the retaining ring 202, the filter bracket 203 and the filter 200.

[0133] The suction cup is used to pick up the membrane; specifically, the suction cup is a vacuum suction cup, so as to make the membrane flat when it is picked up or placed.

[0134] The adhesive applicator is used to apply adhesive to the edges of the pleated filter membrane to be cured on the membrane curing assembly device 100.

[0135] It should be noted that the gripper, suction cup, and glue applicator can be mounted on a single robotic arm 700 to save costs. Of course, considering assembly efficiency, the gripper, suction cup, and glue applicator can also be mounted on different robotic arms 700, or any two can be mounted on a single robotic arm 700, etc.

[0136] In some embodiments, the filter manufacturing equipment 1000 further includes a controller, which is connected to the membrane curing assembly device 100, the robot arm 700, the retaining ring supply device 400 and the membrane sheet supply device 300 respectively. The controller controls the operation of each device, further saving manpower.

[0137] When using the filter manufacturing equipment 1000 provided by the present invention, the retaining ring 202 is placed in the retaining ring holder 401, and the retaining ring 202 falling on the slide rail 402 is pushed to the retaining ring limiting part 402a by the pushing power component, so that the gripper on the robot arm 700 grasps the retaining ring 202 and places the retaining ring 202 into the receiving groove of the negative pressure chamber 103a-1; the laser cutting head cuts the unwound membrane according to the required planar unfolded size of the filter membrane bag and obtains a membrane sheet of a preset shape; the suction cup on the robot arm 700 picks up the membrane sheet and places it onto the membrane positioning component 101, and the push rod 102a presses the membrane sheet down to the slit 101a-1 to achieve folding, and the welding head welds the edges of the folded membrane sheet to be cured together to form a fold. The membrane bag 201a is rotated by the rotary power device 103b, which drives the receiving part 103a to rotate so that the inlet of the negative pressure chamber 103a-1 is directly facing the folded membrane bag 201a. The push rod 102a pushes the folded membrane bag 201a into the negative pressure chamber 103a-1. The negative pressure chamber 103a-1 opens the folded membrane bag 201a through negative pressure suction to form the formed membrane bag 201. The rotary power device 103b drives the receiving part 103a to rotate so that the inlet of the negative pressure chamber 103a-1 faces upward. The gripper of the robot arm 700 places the filter bracket 203 into the formed membrane bag 201 and presses it into place to assemble the filter 200. The gripper takes out the filter 200 and transports it to the tray. After the tray is full, a new tray is replaced.
