Description

Technical Field

[0001] This invention relates to the field of fiberglass filter technology, and in particular to a dispensing and welding device, equipment, and dispensing and welding method for fiberglass filters. Background Technology

[0002] Large fiberglass filters are widely used in industrial air filtration due to their excellent filtration accuracy. The main component of a large fiberglass filter is a cylindrical fiberglass filter element. The filter element is formed by applying adhesive to the vertical edges of glass fibers, and then bonding and fixing the two vertical edges of the glued glass fibers together to form a cylindrical fiberglass filter element.

[0003] Due to the characteristics of glass fiber, glass fiber filter elements are easily damaged and cannot be directly transported and assembled into industrial equipment that requires large glass fiber filters. Therefore, it is necessary to wrap the glass fiber with PP mesh (polypropylene, abbreviated as PP) to protect the glass fiber filter element.

[0004] During the dispensing and bonding process, the glass fiber is usually dispensed manually along the vertical edges, and then the two vertical edges of the dispensed glass fiber are bonded and fixed by hand. However, manual operation inevitably involves contact with the glass fiber, which can damage the product. At the same time, the bonding effect and quality cannot be guaranteed, and the bonding process is time-consuming and labor-intensive.

[0005] Therefore, there is a need to provide a dispensing and welding device for glass fibers that can achieve precise bonding of glass fiber end faces and is not easily damaged during handling and assembly to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a dispensing and welding device for glass fiber filters. This solves the technical problems in the prior art where glass fibers are easily damaged during handling and where manual dispensing and bonding of glass fibers cannot guarantee bonding quality.

[0007] The technical effects of this invention are achieved through the following:

[0008] One aspect provides a dispensing and welding device for a fiberglass filter, including a rotating mechanism and a feeding station, a dispensing station, a bonding and positioning station, and a welding station located at different angular positions on the rotating mechanism. Each of the feeding station, the dispensing station, the bonding and positioning station, and the welding station is equipped with a first base, a web bonding mechanism, and a positioning mechanism.

[0009] The rotating mechanism is used to rotate around its axis to switch the glass fiber and packaging material between the four stations: the feeding station, the dispensing station, the bonding and positioning station, and the welding station.

[0010] The loading station is used to load fiberglass and packaging materials.

[0011] A dispensing mechanism is provided at the relative position of the dispensing station. The dispensing mechanism is used to dispense glue onto the end face of one end of the glass fiber located in the dispensing station when the loading station is switched to the dispensing station after the loading is completed.

[0012] The bonding and positioning station is used to bond the end faces of both ends of the glass fiber through the web bonding mechanism and to position the packaging material through the positioning mechanism.

[0013] A welding mechanism is provided at the relative position of the welding station. The welding station is used to heat the two ends of the packaging material located at the welding station at the same time through the welding mechanism, and then the positioning mechanism is used to stick the two hot-melted edges together to complete the welding process of the packaging material.

[0014] On the other hand, an assembly device for a fiberglass filter is provided, including an end cap assembly device and the aforementioned fiberglass filter dispensing and welding device. The fiberglass filter includes glass fiber, packaging material, an upper end cap fitted on the upper ends of both, and a lower end cap fitted on the lower ends of both. The assembly device is used to complete the dispensing and bonding of the glass fiber and the welding of the packaging material through the dispensing and welding device to obtain a pre-assembled product, and to complete the bonding of the upper and lower end caps of the pre-assembled product through the end cap assembly device to obtain the finished fiberglass filter.

[0015] On the other hand, a dispensing and welding method for a fiberglass filter is provided, the method being implemented based on the aforementioned dispensing and welding apparatus for a fiberglass filter, comprising:

[0016] When the feeding station is completed, control the rotating mechanism to switch the glass fiber and packaging material located at the feeding station to the dispensing station;

[0017] The dispensing mechanism is controlled to move in a first preset direction so that the dispensing nozzle of the dispensing mechanism dispenses glue to the end face of one end of the glass fiber located in the dispensing station. At the same time, the pressing roller of the dispensing mechanism rotates around its axis during the movement of the dispensing mechanism to press the end face of the glass fiber to be dispensed.

[0018] When the glass fiber dispensing is completed, the rotating mechanism is controlled to rotate to switch the glass fiber and packaging material located at the dispensing station to the bonding and positioning station;

[0019] The web bonding mechanism located at the bonding and positioning station controls the end faces of both ends of the glass fiber to bond together, and the positioning mechanism located at the bonding and positioning station completes the positioning of the packaging material.

[0020] The rotating mechanism is controlled to switch the fiberglass and packaging materials located at the bonding and positioning station to the welding station;

[0021] The welding mechanism is controlled to simultaneously heat both ends of the packaging material located at the welding station;

[0022] The control positioning mechanism fits the two hot-melt edges together to complete the welding process of the packaging material.

[0023] The beneficial effects are as follows:

[0024] The dispensing and welding device proposed in this application enables the sequential switching of glass fiber and packaging material between four stations—feeding station, dispensing station, bonding and positioning station, and welding station—through the rotation of the rotating mechanism. This achieves precise bonding of glass fiber and precise welding of the packaging material attached to the outside of the glass fiber, solving the problems of uncontrollable quality in manual bonding of glass fiber and easy damage to glass fiber during handling in the prior art.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example 1:

[0050] like Figure 1-13 As shown in the embodiments of this specification, a dispensing and welding device for a glass fiber filter is provided. The dispensing and welding device is used to complete the bonding of the two end faces of the web-shaped glass fiber to form a cylindrical glass fiber for making a glass fiber filter; at the same time, it is also used to complete the welding process of PP mesh on the outside of the cylindrical glass fiber to wrap around the outside of the cylindrical glass fiber and achieve the protection of the glass fiber.

[0051] The dispensing and welding device in this embodiment includes a rotating mechanism 8 and a feeding station 9, a dispensing station 10, a bonding and positioning station 11, and a welding station 12 located at different angular positions on the rotating mechanism 8. The rotating mechanism 8 is used to rotate around its axis to complete the switching between the four stations of the glass fiber 15 and the packaging material 3, namely the feeding station 9, the dispensing station 10, the bonding and positioning station 11, and the welding station 12, so as to complete the feeding process of the glass fiber 15 and the packaging material 3, the dispensing process of the glass fiber 15, the bonding process of the glass fiber 15, the positioning process of the packaging material 3, and the welding process of the packaging material 3 in sequence at the four stations.

[0052] Specifically, the rotating mechanism 8 includes a rotating support 81, which is a disc-shaped structure. The space where the disc-shaped structure is located is divided into four fan-shaped areas with a central angle of 90 degrees according to different angle directions with its axial direction as the reference, to obtain the feeding station 9, the dispensing station 10, the bonding and positioning station 11 and the welding station 12. The first base 2 is fixedly set at the same relative position in each fan-shaped area, and the web bonding mechanism 13 and the positioning mechanism 1 are set at the same relative position in each first substrate 2.

[0053] The dispensing station 10 is equipped with a dispensing mechanism 14 at a relative position, and the welding station 12 is equipped with a welding mechanism 4 at a relative position.

[0054] The specific production process for the four workstations is as follows:

[0055] The glass fiber 15 and packaging material 3 are loaded at the loading station 9.

[0056] The glass fiber 15 and packaging material 3 located at the loading station 9 are switched to the dispensing station 10, and the dispensing mechanism 14 dispenses glue to one end face of one of the two ends of the glass fiber 15.

[0057] The glass fiber 15 and packaging material 3, which have been dispensed at the dispensing station 10, are switched to the bonding and positioning station 11. The end faces of the two ends of the glass fiber 15 are bonded together by the web bonding mechanism 13 to obtain a tubular glass fiber 15. The two ends of the packaging material 3 are positioned by the positioning mechanism 1 to form a heating gap.

[0058] The glass fiber 15 with its end face bonded and the packaging material 3 with its position completed at the bonding and positioning station 11 are switched to the welding station 12. The welding mechanism 4 extends into the heating gap to heat the two ends of the packaging material 3. After heating, the bonding and welding process of the two ends of the packaging material 3 is completed by the positioning mechanism to obtain the pre-assembled product.

[0059] The pre-assembled product located at welding station 12 is switched to loading station 9 so that the operator at loading station 9 can unload the pre-assembled product and carry out the loading process of new glass fiber 15 and packaging material 3.

[0060] Preferably, the dispensing mechanism 14 includes a dispensing nozzle 141 and a pressing roller 142. The dispensing mechanism 14 moves in a first preset direction under the action of the third driving mechanism. The pressing roller 142 is located in the first preset direction of the dispensing nozzle 141. The axial direction of the pressing roller 142 is perpendicular to the first preset direction. The pressing roller 142 is used to press the end face of the glass fiber 15 to be dispensed by rotating around its axial direction during the movement of the dispensing mechanism 14.

[0061] In this embodiment, the first preset direction is Figure 2 In the upper part of the glass fiber 15, the dispensing nozzle 141 is positioned directly above the pressing roller 142. The dispensing direction of the dispensing nozzle 141 is perpendicular to the end face to be dispensed, and the axis of the pressing roller 142 is parallel to the end face to be dispensed. As the dispensing mechanism 14 moves from the bottom to the top of the end face to be dispensed along the glass fiber 15, the dispensing nozzle 141 simultaneously applies adhesive to the contact area of ​​its end face.

[0062] Specifically, when the glass fiber 15 and packaging material 3 located at the loading station 9 are switched to the dispensing station 10, the dispensing mechanism 14 moves closer to the end face located at the preset dispensing position under the action of the seventh drive mechanism 46, and stops when it moves to the corresponding position. At this time, the dispensing nozzle 141 is controlled to apply glue to the position of its contact end face.

[0063] After moving a preset distance in the first preset direction, the end face adhesive application process is completed. The dispensing mechanism 14 is then controlled to move away from the preset dispensing position and return to the initial position, at which point the dispensing process is complete. In this embodiment, the directions close to and away from the end face to be dispensed are perpendicular to the end face to be dispensed.

[0064] Meanwhile, as the dispensing mechanism 14 moves upward, the pressing roller 142 located above the dispensing nozzle 141 rolls around its axis to press the area to be coated by the dispensing nozzle 141 on the end face flat, making the coating more uniform and the effect better.

[0065] Preferably, the web bonding mechanism 13 includes a linear guide rail 131, a transfer member 132, a fixing member 133, a first web clamping structure 134, and a second web clamping structure 135;

[0066] The linear guide rail 131 is fixedly disposed relative to the first base 2. The transfer member 132 is movably connected to the linear guide rail 131. The transfer member 132 can be detachably connected to the second web clamping structure 135, which is used to fix an edge of a web.

[0067] The fastener 133 is fixedly disposed relative to the linear guide rail 131. The fastener 133 can be detachably connected to the first web clamping structure 134, which is used to fix the edge of another web.

[0068] The transfer member 132 can move closer to or further away from the fixing member 133 along the linear guide 131 to fit the end face of one web edge to the end face of another web edge.

[0069] In this embodiment, the fixing member 133 is fixed to one end of the linear guide rail 131.

[0070] In this embodiment, the first web clamping structure 134 and the second web clamping structure 135 are used to clamp both sides of the glass fiber 15, respectively. With the first web clamping structure 134 fixed on the fixing member 133, when the transfer member 132 slides to the preset position, the end face of one end of the glass fiber 15 clamped by the second web clamping structure 135 is attached to the end face of the other end of the glass fiber 15 clamped by the first web clamping structure 134, thereby completing the bonding of the two end faces of the glass fiber to obtain a cylindrical glass fiber for making a glass fiber filter.

[0071] The sliding process of the transfer component 132 can be controlled manually or by a drive mechanism or a robotic arm.

[0072] It should be noted that after the two sides of the glass fiber 15 are clamped by the first web clamping structure 134 and the second web clamping structure 135 respectively, the end face of the glass fiber is exposed relative to the edge of the corresponding web clamping structure, which facilitates the subsequent end face glue application and bonding operation.

[0073] Preferably, the lower end of the first web clamping structure 134 is provided with a first limiting structure, and the preset dispensing position of the first base 2 is provided with a second limiting structure 201. The first limiting structure can cooperate with the second limiting structure 201 to fix the first web clamping structure 134 at the preset dispensing position of the first base 2. At this time, the end face of the glass fiber 15 to be dispensed is opposite to the dispensing mechanism 14.

[0074] Specifically, the first limiting structure includes several positioning grooves, and the second limiting structure 201 includes several positioning protrusions. The several positioning grooves match the several positioning protrusions, thereby quickly adjusting the relative position of the web clamping structure and the second limiting structure 201 to ensure that the web clamping structure can be quickly and accurately inserted into or removed from the preset dispensing position on the first base 2.

[0075] Among them, some of the positioning grooves in the first limiting structure are provided with magnetic components, and the corresponding positioning protrusions in the second limiting structure 201 are provided with magnetic adsorption components.

[0076] Alternatively, some of the positioning grooves in the first limiting structure may be provided with magnetic adsorption components, and the corresponding positioning protrusions in the second limiting structure 201 may be provided with magnetic components. The mutual adsorption between the magnetic adsorption components can prevent the first sheet clamping structure 134 from tipping over under external force during the dispensing process of the glass fiber end face located at the preset dispensing position.

[0077] By setting up the web bonding mechanism 13, precise bonding between the two end faces of the large-size glass fiber 15 can be achieved, which improves the bonding efficiency and effectively avoids damage to the glass fiber 15 caused by manual bonding.

[0078] Preferably, the positioning mechanism 1 includes two clamping mechanisms 101 and two first guide rails 102 corresponding to each of the two clamping mechanisms 101. The first guide rails 102 are fixedly mounted on the first base 2, and the two clamping mechanisms 101 are arranged opposite to each other.

[0079] The clamping mechanism 101 includes a fixed plate 1011 and an auxiliary positioning plate 1012. The fixed plate 1011 is slidably connected to the corresponding first guide rail 102. The fixed plate 1011 is provided with a limiting member 1013. The packaging material 3 is provided with a limiting hole that matches the limiting member 1013. Both ends of the packaging material 3 pass through the corresponding limiting member 1013 to complete the positioning. The auxiliary positioning plate 1012 and the positioning plate are detachably connected to clamp one end of the corresponding packaging material 3.

[0080] The first base 2 is located in the horizontal direction, and the first guide rail 102 is set parallel to the first base 2.

[0081] The welding mechanism 4 includes a retractable heating structure 401. The packaging material welding device is configured to control the heating structure 401 to extend into the heating gap to simultaneously heat the two ends of the packaging material 3 when a heating gap is formed between the two ends of the packaging material 3. When the heating mechanism 401 retracts, it controls the two clamping mechanisms 101 to move relative to each other to fit the fused ends together and complete the welding process of the packaging material 3.

[0082] Specifically, the two clamping mechanisms 101 are symmetrically arranged, and the positioning mechanism 1 also includes two first driving mechanisms 5. The two first driving mechanisms 5 are respectively driven to connect with the corresponding fixed plates 1011. The two first driving mechanisms 5 are used to synchronously drive the corresponding fixed plates 1011 to move towards each other.

[0083] In this embodiment, the packaging material 3 is a PP mesh material, which will be referred to as PP mesh in the following description. The packaging material welding device in this embodiment is used to weld the PP mesh after bonding the two ends of the web-shaped glass fiber to form a tubular glass fiber for making a glass fiber filter, thereby achieving the encapsulation of the tubular glass fiber.

[0084] like Figure 8 As shown, the two clamping mechanisms 101 are located on the same vertical plane and are arranged symmetrically from left to right, and the two first guide rails 102 are located on the same straight line. The first driving mechanism 5 is a cylinder, and the push rod of the cylinder is fixedly connected to the corresponding fixed plate 1011. The axis of the push rod of the cylinder is parallel to the corresponding first guide rail 102.

[0085] lie in Figure 8 The push rod of the cylinder corresponding to the clamping mechanism 101 on the left side is fixedly connected to the left side of its clamping mechanism 101, and is used to push its clamping mechanism 101 to move to the right along the corresponding first guide rail 102; located in Figure 8 The push rod of the cylinder corresponding to the clamping mechanism 101 on the right side is fixedly connected to the right side of the clamping mechanism 101, and is used to push the clamping mechanism 101 to move to the left along the corresponding first guide rail 10.

[0086] In some other embodiments, the two first guide rails 102 may be two parts of the same linear guide rail.

[0087] Specifically, such as Figure 8 As shown, after the two clamping mechanisms 101 clamp and fix the two ends of the packaging material 3 respectively, the edges of both ends are exposed relative to the corresponding clamping mechanism 101, so that the two clamping mechanisms 101 can be welded together when they move relative to each other.

[0088] The two clamping mechanisms 101 are set to a first preset state and a second preset state under the drive control of the corresponding first drive mechanism 5. For example... Figure 8 As shown, when the two clamping mechanisms 101 are in the first preset state, a heating gap is formed between the two ends of the packaging material 3; when the two clamping mechanisms 101 move relative to each other and change to the second preset state, the two ends of the packaging material 3 abut and fit together.

[0089] Both clamping mechanisms 101 have an arc-shaped structure in the first preset state and the second preset state.

[0090] Specifically, the clamping mechanism 101 also includes a Y-axis moving mechanism 35, which is slidably connected to the corresponding first guide rail 102. The fixing plate 1011 is fixedly connected to the Y-axis moving mechanism 35, and the first driving mechanism 5 is disposed on the Y-axis moving mechanism 35 for pushing the Y-axis moving mechanism 35 to slide along the corresponding first guide rail 102.

[0091] Specifically, the bottom of the Y-axis moving mechanism 35 is fixedly provided with a first connecting member 34, and the first base 2 is provided with a limiting part 43 at the corresponding position when the clamping mechanism 101 is in the first preset state. When the two ends of the packaging material 3 are fixed at the corresponding positions in the first preset state by the two clamping mechanisms 101 respectively, the first connecting member 34 is fixed on the first base 2 by the second connecting member 44 to ensure that the two clamping mechanisms 101 are stably in the first preset state, which facilitates the stability of the heating mechanism 401 when it extends to heat the two edges.

[0092] In this embodiment, the limiting part 43 is a limiting opening, the first connecting member 34 is provided with a connecting hole that matches the limiting opening, and the second connecting member 44 is a bolt. When the clamping mechanism 101 is in the corresponding position of the first preset state, the second connecting member 44 can pass through the connecting hole and the limiting opening in sequence to complete the limiting fixation of the corresponding clamping mechanism 101, thereby ensuring that the heating mechanism 401 heats the two edges evenly.

[0093] In this embodiment, the tubular glass fiber is a cylindrical structure with a circular cross-section, and the PP mesh is a rectangular mesh material. The length of the PP mesh matches the outer perimeter of the tubular glass fiber, and the width of the PP mesh matches the height of the tubular glass fiber.

[0094] Specifically, the welding mechanism 4 also includes a second driving mechanism 6, and the heating mechanism 401 is used to move in the direction of the vertical line of the heating gap under the action of the second driving mechanism 6.

[0095] The heating mechanism 401 is a strip-shaped infrared heater. The length of the infrared heater matches the width of the cylindrical glass fiber, and the width of the infrared heater matches the heating gap. When the infrared heater is located in the heating gap, it emits an infrared beam to heat the edges of both ends of the PP mesh to a molten state.

[0096] The welding process is as follows: Under the drive of the first drive mechanism 5, the two clamping mechanisms 101 are controlled to move relative to each other to the first preset state. After the two ends of the packaging material 3 are bent towards each other, the two ends are accurately fixed in the corresponding clamping mechanisms 101 so that a heating gap is formed between the two ends of the packaging material 3. Under the drive of the second drive mechanism 6, the infrared heater is controlled to move forward a preset distance to extend into the heating gap. The infrared heater is controlled to heat for a preset time to heat the two ends of the PP mesh to the hot melt state.

[0097] The infrared heater is controlled to move backward a preset distance to retract from the heating gap. Under the drive of the first drive mechanism 5, the two clamping mechanisms 101 are controlled to move relative to each other to a second preset state so as to tightly fit the two ends of the molten PP mesh to complete the welding of the PP mesh and realize the encapsulation of the tubular glass fiber 15.

[0098] The forward and backward movements of the infrared heater are respectively in the direction of moving closer to the clamping mechanism 101 and in the direction of moving away from the clamping mechanism 101.

[0099] By using the positioning mechanism 1 and the welding mechanism 4 together, after controlling the relative positions of the two clamping mechanisms 101 to form a heating gap that matches the heating mechanism 401, the heating mechanism 401 extends into the heating gap to uniformly heat the edge of the packaging material 3 located in the heating gap. The two clamping mechanisms 101 then align the edges of the heated packaging material 3 to a molten state, thus realizing the automatic welding process of the packaging material 3. This improves the welding quality of the packaging material 3 and avoids the problem of low welding quality caused by the inability to maintain uniform and stable force during the welding process when manually operating welding tools.

[0100] Preferably, the auxiliary positioning plate 1012 is provided with a plurality of magnetic blocks 1014, and the auxiliary positioning plate 1012 is fixed to the fixing plate 1011 by magnetic blocks 1014, so as to clamp and flatly attach the packaging material 3 limited on the fixing plate 1011 between the auxiliary positioning plate 1012 and the fixing plate 1011.

[0101] In this embodiment, 29 magnetic blocks 1014 are provided on the left and right edges of the surface of the auxiliary positioning plate 1012 near the fixing plate 1011, and the magnetic blocks 1014 on both sides are arranged symmetrically. The 29 magnetic blocks 1014 are evenly distributed on the corresponding edges.

[0102] Specifically, the upper end of the auxiliary positioning plate 1012 is provided with a handle to facilitate the removal of the auxiliary positioning plate 1012 during installation and disassembly.

[0103] By setting magnetic blocks 1014 on the auxiliary positioning plate 1012, the auxiliary positioning plate 1012 can be quickly fixed to clamp the two ends of the packaging material 3 to be welded before welding, and the packaging material 3 can be quickly disassembled after the welding process is completed.

[0104] Preferably, the auxiliary positioning plate 1012 is provided with a mounting hole 1015 at the corresponding position. The size of the mounting hole 1015 is larger than the size of the limiting member 1013. When the auxiliary positioning plate 1012 is attached to the fixing plate 1011, the limiting member 1013 passing through the limiting hole passes through the mounting hole 1015.

[0105] Specifically, both the limiting member 1013 and the limiting hole are symmetrical structures. The limiting hole located at one end of the packaging material 3 is symmetrically arranged at its corresponding end position. In this embodiment, four limiting members 1013 are provided on the back of the fixing plate 1011. The four limiting members 101 are equally spaced in the vertical direction. The limiting member 1013 is a hexagonal prism structure. The limiting holes at both ends of the packaging material 3 are hexagonal openings. The size of the hexagonal openings is consistent with the cross-sectional size of the hexagonal prism structure.

[0106] The mounting hole 1015 is a circular opening, the diameter of which is greater than the maximum width of the limiting member 1013. This allows the mounting hole 1015 to be easily and quickly fitted onto the limiting member 1013 after the packaging material is fitted onto the limiting member 1013 through the limiting hole, thereby clamping both ends of the packaging material 3 between the corresponding fixing plate 1011 and the auxiliary positioning plate 1012.

[0107] By using the auxiliary positioning plate 1012 and the fixing plate 1011 with the limiting member 1013, the two ends of the packaging material 3 can be accurately fixed in the corresponding clamping mechanism 101, thus completing the precise positioning of the two ends of the packaging material 3. By controlling the distance between the two clamping mechanisms 101, the required heating gap can be accurately formed between the edges of the packaging material 3, so as to ensure that the heating mechanism 401 heats each area of ​​its edge evenly, and after heating and melting, it can ensure accurate fit between the corresponding positions of the two ends, thereby improving the welding accuracy.

[0108] Preferably, the first base 2 is further provided with an unfolding auxiliary mechanism 36 and an arc-shaped limiting mechanism 7. The arc-shaped limiting mechanism 7 and the positioning mechanism 1 are arranged opposite to each other. The arc-shaped limiting mechanism 7 is used to limit the packaging material 3 placed on the first base 2. The unfolding auxiliary mechanism 36 is located inside the arc-shaped limiting mechanism 7.

[0109] When it is necessary to feed the glass fiber 15 and the packaging material 3 onto the first base 2 located at the feeding station 9, the strip-shaped glass fiber 15 is sleeved on the unfolding auxiliary mechanism 36, and the packaging material 3 is wrapped around the outside of the glass fiber 15 and placed inside the arc-shaped limiting mechanism 7, so as to achieve the arc-shaped placement of the glass fiber 15 and the packaging material 3 in the corresponding positions.

[0110] By keeping the corresponding position of the packaging material 3 in an arc shape, it is easy to remove the two ends of the packaging material 3 and fix them in the clamping mechanism 101 after the glass fiber 15 is glued and fixed.

[0111] It should be noted that, as Figure 6 As shown, when the packaging material 3 is placed around the outside of the glass fiber 15, the two clamping mechanisms 101 are in the third preset state, that is, in a relatively far apart state. Under this condition, the two ends of the packaging material 3 located inside the arc-shaped limiting mechanism 7 are bent in a relatively far apart direction, and the two ends are fixed in the corresponding clamping mechanism 101 respectively. At this time, the packaging material 3 is placed in a Z-shape to avoid the dispensing space and facilitate the subsequent dispensing operation.

[0112] In this embodiment, when the two clamping mechanisms 101 are in the third preset state, the two clamping mechanisms 101 are respectively located on the edge of the corresponding first guide rail 102. At this time, the distance between the two clamping mechanisms 101 is the farthest.

[0113] The first base 2 is also provided with limiting openings at the corresponding positions of the two clamping mechanisms 101 in the third preset state, so that when the clamping mechanism 101 is in the third preset state, the second connector 44 can pass through the connecting hole and the limiting opening on the first connector 34 in sequence to complete the limiting fixation of the corresponding clamping mechanism 101, thereby ensuring the stability of the packaging material 3 placed in a Z-shape.

[0114] It should be noted that before the welding process, the two ends of the packaging material 3 need to be bent towards each other and fixed in the corresponding clamping mechanism 101. At this time, the clamping mechanism 101 is in the first preset state, and the packaging material 3 has an arc-shaped structure. Before the glue dispensing process, the two ends of the packaging material 3 need to be far apart to avoid glue dispensing space. Therefore, the two ends of the packaging material 3 need to be bent in the relatively far apart direction and fixed in the corresponding clamping mechanism 101. At this time, the clamping mechanism 101 is in the third preset state, and the packaging material 3 has a Z-shaped structure.

[0115] Therefore, the limiting member 1013 and the limiting hole need to meet the following conditions: the limiting member 1013 and the limiting hole are both left-right symmetrical structures; the limiting hole located at one end of the packaging material 3 is left-right symmetrically arranged at its corresponding end position.

[0116] Specifically, the dispensing and welding device also includes an eighth drive mechanism 37. The eighth drive mechanism 37 is located below the rotating support 81 and is drivenly connected to the rotating support 81. It drives the rotating support 81 to rotate around its axis in a preset direction, sequentially completing the switching process between four stations: the loading station 9, the dispensing station 10, the bonding and positioning station 11, and the welding station 12, for the glass fiber 15 and the packaging material 3. The preset direction is... Figure 14 The clockwise direction of the location of the dispensing and welding device.

[0117] Specifically, such as Figure 14 As shown, loading station 9 is located in Figure 14 On the far right of the dispensing and welding device, the dispensing station 10, the bonding and positioning station 11, and the welding station 12 are located in the corresponding positions of the first base 2 in a clockwise direction.

[0118] When the rotating support 81 rotates 90 degrees clockwise, the first base 2 located on the loading station 9 and the glass fiber 15 and packaging material 3 it carries are switched to the dispensing station 10. In this way, by sequentially completing the switching process between the four stations of loading station 9, dispensing station 10, bonding and positioning station 11 and welding station 12, the dispensing and bonding operation of glass fiber 15 and the welding operation of packaging material 3 are completed.

[0119] Specifically, the dispensing and welding device of this application also includes a base 38, a rotating bearing seat 81 is disposed above the base 38, and the base 38 is provided with a support component 39 at each corresponding position of each work station. The support component 39 includes a fixed seat 391 and a support roller 392. The fixed seat 391 is fixed on the base 38, and the support roller 392 is rotatably connected to the fixed seat 391. An abutment block 40 is provided below the rotating bearing seat 81 at a position opposite to the support roller 392.

[0120] When the rotating support seat 81 rotates to switch the glass fiber 15 and packaging material 3 to the corresponding work station, the abutment block 40 is located directly above the corresponding support roller 392, and the support roller 392 abuts against the abutment block 40, so that the rotating support seat 81 is supported from four positions, so that when the glass fiber 15 and packaging material 3 are switched to the corresponding work station, the rotating support seat 81 at each work station can be supported from four directions to keep it stable and horizontal.

[0121] The abutment block 40 has guide portions on both sides. The guide portions are arc-shaped and their thickness gradually decreases from the middle position to the edge position. This allows the abutment block 40 to easily rotate to the top of the support assembly 39 during the rolling of the support roller 392 when a portion of the rotating support seat 81 carrying the glass fiber 15 and packaging material 3 is about to rotate to the corresponding work position.

[0122] Specifically, such as Figure 13 As shown, a positioning detection device 41 is provided below the corresponding positions of the material loading station 9, the glue dispensing station 10, the bonding and positioning station 11, and the welding station 12. The positioning detection device 41 is used to detect that the corresponding station switch is completed when switching from the previous station to the corresponding station.

[0123] When the positioning detection device 41 at the corresponding position of the dispensing station 10 detects that the glass fiber 15 and packaging material 3 at the loading station 9 have been switched to the dispensing station 10, it controls the dispensing mechanism 14 to move towards the preset dispensing position to the front of the end face to be dispensed, so that the dispensing nozzle 141 contacts the bottom or top of the end face to be dispensed.

[0124] The heating mechanism 401 of the welding mechanism 4 moves toward the heating gap, which is also triggered by the corresponding positioning detection device 41 of the welding station 12.

[0125] This specification provides an embodiment of a dispensing and welding method for a fiberglass filter. The method is based on the dispensing and welding apparatus for the fiberglass filter described in Embodiment 1, and includes:

[0126] The two ends of the glass fiber 15 are clamped and fixed by the first web clamping structure 134 and the second web clamping structure 135, respectively.

[0127] After attaching 3 packs of packaging material to 15 glass fiber, place them simultaneously on the outside of the unfolding auxiliary mechanism 36 and the inside of the arc-shaped limiting structure 7.

[0128] The other end of the glass fiber 15 is clamped and fixed by the first web clamping structure 134 and the second web clamping structure 135 is fixed to the transfer member 132.

[0129] One end of the glass fiber 15, which is clamped and fixed by the first sheet clamping structure 134, is fixed to the preset dispensing position of the first base 2 so that its corresponding end face is set opposite to the dispensing mechanism 14 when the dispensing station 10 is switched.

[0130] The clamping mechanisms 101 are moved away from each other until they are in a third preset state;

[0131] After bending both ends of the packaging material 3 in a direction that is relatively far apart, they are respectively fixed in the corresponding clamping mechanism 101;

[0132] When the glass fiber 15 and packaging material 3 located at the loading station 9 are detected to switch to the dispensing station 10, the dispensing mechanism 14 is controlled to move to the corresponding position in the direction toward the end face located at the preset dispensing position.

[0133] The dispensing mechanism 14 is controlled to move in a first preset direction so that the dispensing nozzle 141 of the dispensing mechanism 14 dispenses glue to the end face located at the preset dispensing position.

[0134] At the same time, the pressing roller 142 of the dispensing mechanism 14 rotates around its axis during the movement of the dispensing mechanism 14 to press the end face of the glass fiber 15 to be dispensed.

[0135] After the glue application is completed, the glue dispensing mechanism 14 moves in a direction away from the end face located at the preset glue dispensing position and then moves in the opposite direction to the initial position.

[0136] When the glass fiber 15 and packaging material 3 located at the loading station 9 are switched to the dispensing station 10, the second strip clamping structure 135 is removed from the preset dispensing position and can be detachably fixed to the fixing member 133.

[0137] The transfer component 132 is controlled to move on the linear guide 131 toward the fixing component 133 so as to align and bond the other end face of the glass fiber 15 held by the second web clamping structure 135 mounted on the transfer component 132 with the end face after dispensing.

[0138] Remove both ends of the packaging material 3 from the corresponding clamping mechanism 101, and control the clamping mechanism 101 to drive the corresponding fixing plate 1011 to move towards each other to the first preset state;

[0139] The two ends of the packaging material 3 are respectively passed through the corresponding limiting members 1013 on the fixing plate 1011 to complete the limiting of the two ends of the packaging material 3 in their corresponding bonding and welding directions.

[0140] The auxiliary positioning plate 1012 is sleeved on the corresponding limiting member 1013 so that the auxiliary positioning plate 1012 is attracted and fixed on the fixing plate 1011 under the magnetic force of the magnetic block 1014 on the auxiliary positioning plate 1012, so that the packaging material 3 limited on the fixing plate 1011 is clamped and flatly attached between the auxiliary positioning plate 1012 and the fixing plate 1011, and a heating gap is formed between the two ends of the packaging material 3.

[0141] When the glass fiber 15 and packaging material 3 located at the bonding and positioning station 11 are switched to the welding station 12, the heating structure 401 of the control welding mechanism 4 extends into the heating gap to heat the two ends of the packaging material 3 simultaneously.

[0142] After heating is completed, the heating structure 401 of the control welding mechanism 4 retracts to its corresponding initial position;

[0143] The clamping mechanism 101 is controlled to move towards each other to the second preset state so that the two hot-melt edges are brought together to complete the welding of the packaging material 3, so that the packaging material 3 is tightly attached to the outside of the tubular glass fiber 15.

[0144] The dispensing mechanism 14 is configured with a designated end position for dispensing. When the dispensing mechanism 14 moves to the designated position, the dispensing process is considered complete, and it automatically returns to its initial position. When a sensor located near the initial position of the dispensing mechanism 14 detects that the dispensing mechanism 14 has returned to its initial position, it controls the rotating mechanism 8 to rotate, thereby switching to the bonding and positioning station 11.

[0145] A sensor is installed near the welding mechanism 4. When the sensor detects that the heating mechanism 401 has returned to its corresponding initial position, it controls the rotating mechanism 8 to rotate to switch to the welding station 12.

[0146] In some other embodiments, a sensor for the location of the heating mechanism 401 after heating is completed can also be set on the first base 2 near the heating gap. When the heating mechanism 401 is detected to have reached a safe position, the rotating mechanism 8 is controlled to rotate to switch to the welding station 12.

[0147] Example 2:

[0148] like Figure 14-21 As shown in the figure, this specification provides an assembly device for a fiberglass filter, including an end cap assembly device and a dispensing and welding device for the fiberglass filter in embodiment 1. The fiberglass filter includes glass fiber 15, packaging material 3, an upper end cap 16 sleeved on the upper end face of both and a lower end cap 17 sleeved on the lower end face of both.

[0149] The assembly equipment is used to complete the dispensing and bonding of glass fiber 15 and the welding of packaging material 3 through the dispensing and welding device to obtain a pre-assembled product. Then, the upper and lower end faces of the pre-assembled product are bonded to the upper end cover 16 and the lower end cover 17 respectively through the end cover assembly device to obtain the finished glass fiber filter.

[0150] Specifically, the end cap assembly device includes an upper end cap assembly device and a lower end cap assembly device. Both the upper end cap assembly device and the lower end cap assembly device include a transplanting mechanism 24 and an end cap positioning mechanism. This application will use the upper end cap assembly device as an example to describe the end cap positioning mechanism and the transplanting mechanism 24.

[0151] Specifically, the end cap positioning mechanism includes:

[0152] Support member 18 is used to support the annular end cap.

[0153] A positioning fixture 19 is disposed inside the support member 18. The positioning fixture 19 includes at least two positioning blocks 191. Under the action of the fourth drive mechanism 20, the positioning fixture 19 switches from a first state to a second state. When the positioning fixture 19 is in the second state, the positioning blocks 191 abut against the inner wall of the annular end cap located on the support member 18 to position the end cap.

[0154] The limiting fixture 21 is located on the outside of the carrier 18. The limiting fixture 21 includes two clamping blocks 211. The two clamping blocks 211 are arranged opposite to each other. The two clamping blocks 211 press against the outer wall of the positioned end cap through relative movement to place the annular workpiece to be assembled.

[0155] In this embodiment, the end cap positioning mechanism is used to assist in the assembly process of the upper end cap 16 and the lower end cap 17, which consist of an upper end cap cylindrical glass fiber and a PP mesh wrapped around its outer side. This application uses the assembly process of the upper end cap as an example to illustrate the positioning principle of the end cap positioning mechanism.

[0156] It should be noted that, since the upper end cap 16 and lower end cap 17 commonly used in fiberglass filters are made of easily deformable materials, they cannot be kept in a standard circular shape. This makes it difficult to manually place the ring-shaped pre-assembled product into the corresponding end cap in one go, resulting in a relatively difficult assembly operation.

[0157] Therefore, this application provides a positioning fixture 19 on the inner side and a limiting fixture 21 on the outer side of the carrier 18, so that while positioning the upper cover 16, the inner and outer sides of the shape of the upper cover 16 are limited to ensure that the upper cover 16 is in a relatively regular annular shape, thereby facilitating the accurate placement of the annular product into the upper cover 16 to complete the assembly process.

[0158] Preferably, the outer side of the positioning block 191 includes a positioning area 1911 for positioning the end cap and a second guide area 1912 located at the upper end of the positioning area 1911 with an enlarged outer diameter in the vertical direction, the length of the second guide area 1912 being greater than the length of the positioning area 1911.

[0159] The bottom dimension of the second guide area 1912 is larger than that of the positioning area 1911, meaning that the largest dimension of the second guide area 1912 is a protruding structure relative to the positioning area 1911. The length of the positioning area 1911 is greater than the length of the inner wall of the upper end cover 16.

[0160] In this embodiment, the outer side of the positioning area 1911 is an arc surface. There are four positioning blocks 191, distributed in the four directions of up, down, left, and right. There are two fourth driving mechanisms 20. The positioning blocks 191 located in the up and down directions move up and down respectively under the driving action of the same fourth driving mechanism 20; the positioning blocks 191 located in the left and right directions move left and right respectively under the driving action of the same fourth driving mechanism 20.

[0161] With the positioning fixture 19 in its first state, the dispensing-completed upper cap 16 is placed onto the carrier 18 along the second guide area 1912 of the positioning block 191. The positioning fixture 19 then switches from the first state to the second state, positioning the positioning area 1911 of the positioning block 191 against the inner wall of the upper cap 16 on the carrier 18, completing the loading process of the upper cap 16. At this time, the maximum size of the second guide area 1912 is located above the upper cap 16.

[0162] When the positioning fixture 19 is in the first state, the four positioning blocks 191 are in a converged state; when the positioning fixture 19 is in the second state, the four positioning blocks 191 are in a spread-out state. When the positioning fixture 19 switches from the first state to the second state, the four positioning blocks 191 move simultaneously up, down, left, and right, respectively, so that the positioning areas 1911 of the four positioning blocks 191 simultaneously abut against the relative positions of the inner wall of the upper end cover 16, so as to evenly spread the upper end cover 16 from four directions, keeping its inner wall in a standard circular shape, and realizing the accurate positioning of the upper end cover 16 in the end cover positioning mechanism.

[0163] When the four positioning blocks 191 are in a converged state, the circular size formed by the largest size position on the second guide area 1912 of the four positioning blocks 191 matches the inner diameter of the upper end cover 16.

[0164] Preferably, the inner side of the clamping block 211 includes a limiting area 2111 for pressing the end cap and a first guide area 2112 located at the upper end of the limiting area 2111 with an increased inner diameter in the vertical upward direction, the length of the first guide area 2112 being greater than the length of the limiting area 2111.

[0165] Specifically, the inner side of the limiting area 2111 is semi-circular. The bottom dimension of the first guide area 2112 is larger than the dimension of the limiting area 2111, that is, the maximum dimension of the first guide area 2112 is a protruding structure relative to the limiting area 2111.

[0166] Preferably, it also includes a second base 23 with a second guide rail 22, the carrier 18 is fixed on the second base 23, and the two clamping blocks 211 are slidably connected to the second guide rail 22. After the end cover is positioned by the positioning fixture 19, the two clamping blocks 211 move relative to each other along the second guide rail 22 to press against the outside of the end cover to complete the limiting of the end cover.

[0167] Specifically, the second base 23 is provided with a rectangular slot 42, the center of which coincides with the center of the support member 18. The support member 18 is composed of two symmetrically arranged arc-shaped structures, and the groove design of the arc-shaped structures matches the end cap to be supported. The rectangular slot 42 is located between the two arc-shaped structures. The length of the rectangular slot in the Y direction is greater than the maximum width of the end cap to be supported by the support member 18.

[0168] It should be noted that the end cap positioning mechanism of this application is used to position the upper end cap 16 and ensure that the upper end cap 16 is in a relatively regular annular shape, thereby facilitating the accurate placement of the glass fiber 15 wrapped with PP mesh into the upper end cap 16 under the limiting action provided by the end cap positioning mechanism to complete the assembly and bonding of the upper end cap.

[0169] Since the glass fiber 15 is a soft material, it is easily damaged during handling and placement. It is necessary to avoid direct handling or squeezing by humans. Therefore, a rectangular slot 42 is provided on the second base 23 so that after the glass fiber 15 wrapped with PP mesh is assembled with the upper cover, the product can be lifted from below the upper cover 16 by a person through the rectangular slot 42, so as to facilitate quick handling and placement of the product and avoid damage to the glass fiber 15 caused by manual squeezing.

[0170] After the upper cover 16 is positioned, the two clamping blocks 211 are controlled to move relative to each other and press against the outer wall of the positioned upper cover 16, thus defining the shape of the outer wall of the upper cover 16 and limiting the glass fiber that will be wrapped with PP mesh. At this time, the maximum size of the first guide area 2112 is located above the upper cover 16.

[0171] In this embodiment, each of the two clamping blocks 211 is provided with a handle. When the two clamping blocks 211 are moved relative to each other by the two handles until they are closed, the limiting operation is completed.

[0172] In some other implementations, the two clamping blocks 211 can be driven by corresponding drive mechanisms to move synchronously toward each other and away from each other.

[0173] When the positioning fixture 19 and the limiting fixture 21 work together to position and limit the upper cover 16, the maximum size position of the second guide area 1912 and the maximum size position of the first guide area 2112 are located above the upper cover 16. At this time, the maximum size positions of the second guide area 1912 and the first guide area 2112 are on the same horizontal plane, and the thickness of the ring formed between the maximum size positions of the second guide area 1912 and the first guide area 2112 is less than the sum of the thicknesses of the glass fiber 15 and the PP mesh.

[0174] During the process of placing the glass fiber with PP mesh attached into the upper cover 16 along the second guide area 1912 and the first guide area 2112, when the glass fiber with PP mesh attached reaches the maximum size position of the second guide area 1912 and the maximum size position of the first guide area 2112, the two guide areas press the glass fiber with PP mesh attached to a smaller thickness, so that during the process of pressing down the glass fiber with PP mesh attached, both can quickly fall into the upper cover 16, completing the assembly process.

[0175] It should be noted that, because fiberglass is a soft material, the tubular fiberglass is an irregular cylinder. This makes it difficult to match the end face shape of the two materials with the groove shape of the lower end cap when manually taking the tubular fiberglass with PP mesh attached and placing it on the lower end cap, so that they can be inserted into the lower end cap in one go. This makes the assembly operation more difficult.

[0176] Therefore, by combining the first guide area 2112 and the second guide area 1912, the cylindrical glass fiber with PP mesh attached to be placed in the upper cover 16 can be guided well. This makes it easy to assemble the upper cover 16 of the easily deformable PP mesh and the relatively soft cylindrical glass fiber, saving the operation time of manually adjusting the shape of the cylindrical glass fiber and PP mesh, and avoiding the problem of damage to the glass fiber caused by manual operation.

[0177] Specifically, the transplanting mechanism 24 includes a lower pressure plate 241 located in the horizontal direction. The transplanting mechanism 24 presses down the glass fiber 15 and the packaging material 3 covering its outer side through the lower pressure plate 241 to maintain a pre-compression time so that the end faces of the two are bonded to the upper end cap 16 which has been glued.

[0178] Furthermore, the upper cover assembly device also includes a fifth drive mechanism 25 and a sixth drive mechanism 26. The fifth drive mechanism 25 is driven to connect with the transplanting mechanism 24 and is used to drive the transplanting mechanism 24 to move in the horizontal direction. The sixth drive mechanism 26 is driven to connect with the lower pressure plate 241 and is used to drive the lower pressure plate 241 to move in the vertical direction.

[0179] The fifth drive mechanism 25 and the sixth drive mechanism 26 are cylinders. After the sixth drive mechanism 26 descends to tightly press the lower pressure plate 241 against the lower end face of the glass fiber 15 and the PP mesh attached to its outer side, the pressure is maintained for a pre-pressing time to complete the pressure holding process of assembling the upper end cap. When the pre-pressing time ends, the sixth drive mechanism 26 moves upward to return to its initial position, and the fifth drive mechanism 25 moves backward to return to its initial position, thus completing the assembly process of the upper end cap of the glass fiber 15 and the PP mesh attached to its outer side.

[0180] It should be noted that in this embodiment, the lower end cover assembly device also includes a fifth drive mechanism 25 and a sixth drive mechanism 26. Although the fifth drive mechanism 25 and the sixth drive mechanism 26 of the lower end cover assembly device have the same drive structure as the fifth drive mechanism 25 and the sixth drive mechanism 26 of the upper end cover assembly device, the drive direction of the fifth drive mechanism 25 of the lower end cover assembly device is different from that of the fifth drive mechanism 25 of the upper end cover assembly device.

[0181] Meanwhile, due to the installation requirements of the fiberglass filter, the structural designs of the upper end cover 16 and the lower end cover 17 of the fiberglass filter in this embodiment are different. Therefore, the carrier 18 in the lower end cover assembly device is different from the carrier 18 in the upper end cover assembly device.

[0182] The lower end cover assembly device also includes a pressure holding mechanism 27 and a conveying mechanism 28. The pressure holding mechanism 27 includes a pressure holding plate 271 with multiple stations, and the lower surface of the pressure holding plate 271 matches the upper surface of the upper end cover 16.

[0183] Specifically, the upper surface of the upper cover 16 is provided with an annular protrusion structure. Therefore, when the lower pressure plate 241 of the lower cover assembly device is pressed down, it may not be completely flat against the upper cover 16.

[0184] The conveying mechanism 28 is used to carry the annular workpiece with the lower end cap 17 attached for the pressure holding process. When the pressure holding mechanism 27 completes the bonding of the annular workpiece with the corresponding lower end cap 17 at multiple stations, the conveying mechanism 28 rotates in the discharge direction to convey the assembled glass fiber filter to the discharge area.

[0185] This specification provides an embodiment of a method for assembling end caps of a fiberglass filter. The method is based on the upper end cap assembly device and lower end cap assembly device described in Embodiment 3, and includes:

[0186] When the upper cap 16, after the glue has been applied, is placed on the carrier 18 of the upper cap assembly device, the positioning block 191 is controlled to move synchronously so that the positioning fixture 19 switches from the first state to the second state to open the upper cap 16, thereby achieving the positioning of the upper cap 16.

[0187] The clamping block 211 of the control limiting fixture 21 moves relative to each other so that the limiting area 2111 of the clamping block 211 presses against the outer wall of the upper end cover 16 to achieve the limiting of the upper end cover 16.

[0188] The annular workpiece is placed into the upper end cover 16 under the guidance of the first guide area 2112 located at the upper end of the limiting area 2111 on the clamping block 211, which has an enlarged inner diameter in the vertical upward direction;

[0189] The transfer mechanism 24 of the control upper end cap assembly device is moved to above the end cap positioning mechanism;

[0190] The lower pressure plate 241 of the transplanting mechanism 24 is controlled to press down on the annular workpiece to be assembled and maintain the pre-pressure time so that the annular workpiece is bonded to the upper end cover 16.

[0191] The control device for assembling the lower end cover completes the assembly of the lower end cover 17 through its end cover positioning mechanism and presses down the upper end cover 16 through the pressure plate 271 of its pressure holding mechanism 27 so that the annular workpiece after the upper end cover 16 is assembled is bonded to the lower end cover 17.

[0192] The lower end cap 17 is positioned by the end cap positioning mechanism of the lower end cap assembly device, which also serves to limit and guide the glass fiber 15 and PP mesh that are about to be placed in.

[0193] The assembled glass fiber 15 and PP mesh of the upper end cover 16 are placed vertically upward in the lower end cover 17;

[0194] The lower pressure plate 241 of the transfer mechanism 24 of the lower end cover assembly device presses down on the upper end cover 16 to complete the assembly process of the lower end cover.

[0195] The glass fiber 15 and PP mesh, which are assembled with the upper end cover 16 and the lower end cover 17, are placed on the vertically upward conveying mechanism 28;

[0196] The pressure holding mechanism 27 moves downward under the action of its corresponding drive mechanism to press tightly against the corresponding position of the upper end cover 16 to complete the pressure holding process and obtain the finished glass fiber filter;

[0197] After the pressure holding process is completed, the control conveying mechanism 28 conveys the finished product to the discharge area to complete the entire production process of the glass fiber filter.

[0198] On the other hand, such as Figure 22As shown in the figure, this specification provides a pneumatic expansion clamping fixture for picking up and placing cylindrical glass fibers 15 during the assembly of a glass fiber filter, comprising:

[0199] Fixture 29,

[0200] A sealing support 30 is sleeved on a fixed frame 29. The sealing support 30 has an inner cavity 301. The inner cavity 301 is normally in a deflated state. When the inner cavity 301 is in a deflated state, the maximum width of the pneumatic expansion fixture is less than the inner diameter of the glass fiber 15. When the pneumatic expansion fixture is placed inside the glass fiber 15, the inner cavity 301 changes from a deflated state to an inflated state so that the sealing support 30 abuts against and adheres to the inner wall of the glass fiber 15.

[0201] Preferably, the fixing frame 29 has a disc-shaped structure, and the edge of the fixing frame 29 is provided with an annular groove. The sealing support 30 has an annular structure and is snapped into the groove.

[0202] Specifically, under normal conditions, the inner cavity 301 of the support is in a deflated state, and in this state, the sealing support 30 fits into the groove on the outer periphery of the fixing frame 29. When the pneumatic tightening fixture is horizontally placed inside the annular glass fiber 15, the inner cavity 301 of the support is inflated, changing it from a deflated state to an inflated state, so that the sealing support 30 abuts against the inner wall of the glass fiber 15. Thus, during the process of holding the pneumatic tightening fixture, the static friction generated between the sealing support 30 and the glass fiber 15 enables the handling of the cylindrical glass fiber 15, avoiding the problem of damage to the glass fiber 15 caused by manual handling.

[0203] Furthermore, while the tooling is inflated and pressed against the inner wall of the glass fiber 15 to fix the glass fiber 15, it also allows the outer wall to make close contact with the PP mesh attached to its outer side at the position corresponding to the contact position. This allows static friction to be generated simultaneously between the sealing support 30 and the inner wall of the glass fiber 15, and between the outer wall of the glass fiber 15 and the PP mesh. This enables the simultaneous handling of the glass fiber 15 and the PP mesh, avoiding the problem of the relative position of the glass fiber 15 and the PP mesh shifting during manual handling, which would be inconvenient for subsequent end cap assembly.

[0204] In this embodiment, the annular glass fiber 15 is a standard cylindrical structure, and the plane where the contact point is located is perpendicular to the axial direction of the glass fiber 15.

[0205] Preferably, the bottom of the groove is provided with multiple openings, and the sealing support 30 is provided with an air tube 302 at the position that fits the openings, and the size of the air tube 302 matches the size of the corresponding opening.

[0206] Preferably, the pneumatic expansion fixture of this application further includes an inlet / outlet air pipe 31 and an air distribution block 32. The inlet / outlet air pipe 31 and the air distribution block 32 are both fixedly mounted on the fixed frame 29. The inlet / outlet air pipe 31 and the air distribution block 32 are connected. The air distribution block 32 is provided with at least two air distribution ports 321. The inflation gas entering through the inlet / outlet air pipe 31 passes through the air distribution block 32 and is discharged from the air distribution ports 321 into the corresponding air pipe 302.

[0207] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
