Abstract

This invention belongs to the field of filter manufacturing technology and discloses a glue injection device and method. The glue injection device includes a support frame, a mounting plate, a clamping assembly, a rotary extrusion mechanism, a glue injection head, and a drive assembly. The mounting plate has an inclined state and a vertical state; the clamping assembly is disposed on the mounting plate and used to clamp the filter; the rotary extrusion mechanism is disposed on the mounting plate and is used to extrude the filter to expose the glue tank and drive the filter to rotate; the drive assembly is used to drive the mounting plate to switch between the inclined and vertical states. In the inclined state, the glue injection head corresponds to the filter to inject glue into the filter; in the vertical state, the filter stands upright to ensure uniform distribution of the glue.

Description

Technical Field

[0001] This invention relates to the field of filter manufacturing technology, and more particularly to glue injection equipment and glue injection method. Background Technology

[0002] The filter mainly consists of five parts: housing, sealing ring, cover plate, spring and filter element. The housing has a J-shaped rolled edge inside, which serves as a glue groove to hold the glue. The threaded cover plate is inserted into the glue groove so that the glue solidifies and fixes the threaded cover plate to the housing.

[0003] In the existing technology, the following methods are mainly used for injecting glue into the glue tank. The first method is to directly apply the glue into the glue tank and then assemble the threaded cover plate and the outer shell. The second method is to first assemble the threaded cover plate and the outer shell, then apply the glue into the gap between the two, and use a rotating filter to throw the glue into the glue tank. The third method is to first assemble the outer shell and the threaded cover plate, then clamp the filter in the glue-spinning disc and lift the threaded cover plate. The glue-spinning disc can throw the glue onto the outer shell wall, and the glue flows into the glue tank by its own weight.

[0004] Although all three methods can achieve glue injection, the glue itself has poor fluidity, making it difficult to distribute the glue evenly in the glue tank. This can easily lead to poor fixation of the threaded cover plate and the outer shell in certain areas, affecting the quality and service life of the filter. Summary of the Invention

[0005] The purpose of this invention is to provide a glue injection device and a glue injection method, which solves the problem in the prior art that the glue is difficult to distribute evenly in the glue tank, resulting in poor fixing effect between the threaded cover plate and the outer shell, which affects the quality and service life of the filter.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a dispensing apparatus, comprising:

[0008] Support frame;

[0009] A mounting plate is movably connected to the support frame, and the mounting plate has an inclined state and a vertical state.

[0010] A clamping assembly is disposed on the mounting plate and used to clamp the filter;

[0011] A rotary extrusion mechanism is provided on the mounting plate. The rotary extrusion mechanism is used to extrude the filter to expose the glue tank and drive the filter to rotate.

[0012] The dispensing head has one end for connecting to the dispensing equipment and the other end for corresponding to the glue tank of the filter; and

[0013] A drive assembly, connected to the mounting plate, drives the mounting plate to switch between the tilted state and the vertical state. In the tilted state, the dispensing head corresponds to the filter to dispense adhesive into the filter. In the vertical state, the filter is upright so that the adhesive is evenly distributed.

[0014] Optionally, the rotary extrusion mechanism includes:

[0015] A sliding plate, slidably connected to the mounting plate;

[0016] A pressing head is rotatably connected to the sliding plate and is used to abut against the housing of the filter.

[0017] A support head, disposed opposite to and rotatably connected to the mounting plate, is used to abut against the end cap of the filter to push the end cap relative to the housing and expose the rubber groove; and

[0018] A sliding drive element is connected to the pressing head to drive the pressing head to rotate.

[0019] Optionally, the rotary extrusion mechanism further includes:

[0020] A rotary drive is connected to the support head to drive the support head to rotate.

[0021] Optionally, the rotary extrusion mechanism includes:

[0022] A synchronous drive unit is connected to the other of the pressing head and the support head, and a synchronous rotation drive unit is used to drive the support head or the pressing head to rotate.

[0023] Optionally, the axis of the pressing head is collinear with the axis of the support head.

[0024] Optionally, the mounting plate has an adjustment hole, and the dispensing head passes through the adjustment hole and can slide relative to the mounting plate.

[0025] Optionally, the driving component includes:

[0026] The drive cylinder is rotatably connected to the support frame; and

[0027] A connecting seat is disposed on the mounting plate and hinged to the piston rod of the drive cylinder.

[0028] Optionally, the clamping assembly includes:

[0029] A clamping seat, disposed on the mounting plate and used to support the filter; and

[0030] A clamping element is disposed on the mounting plate and is used to clamp the filter and is rotatably connected to the filter.

[0031] Optionally, the clamping assembly further includes:

[0032] The roller is rotatably connected to the clamping seat and abuts against the surface of the filter.

[0033] In a second aspect, the present invention provides a dispensing method, which is applied to the dispensing equipment described in any one of the first aspects, comprising:

[0034] The drive assembly is controlled to tilt the mounting plate, the filter is acquired, and the clamping assembly is used to clamp the filter onto the mounting plate.

[0035] The rotary extrusion mechanism is controlled to extrude the filter and expose the glue tank;

[0036] The glue injection head is aligned with the glue tank of the filter to inject glue, and the rotary extrusion mechanism is controlled to drive the filter to rotate.

[0037] After the glue is applied, the glue head is separated from the filter, and the drive assembly is controlled to switch the mounting plate to a vertical position so that the filter is upright and the glue is evenly distributed in the glue tank.

[0038] The beneficial effects of this invention are:

[0039] Firstly, by clamping the filter onto an inclined mounting plate using a clamping assembly, the filter is positioned at a certain angle. A rotary extrusion mechanism then presses the filter to expose it in the glue tank. Glue is then injected into the tank through an injection head. During injection, the rotary extrusion mechanism continuously rotates the filter, ensuring even filling of the glue tank with glue. After injection, a drive assembly switches the mounting plate to a vertical position, placing the filter upright. The glue then flows evenly into the glue tank under its own weight. Therefore, this glue injection equipment assembles the filter first, then presses it into the glue tank and rotates the filter to evenly inject the glue. When the filter is upright, the glue is evenly distributed in the tank, ensuring a stable connection between the various parts of the filter, thus guaranteeing filter quality and extending its service life.

[0040] Secondly, this method exposes the glue tank during glue injection, allowing the glue to enter quickly and thus rapidly completing the glue injection process and improving efficiency. During injection, tilting and rotating the filter first ensures the glue is evenly injected into the tank. Then, straightening the filter ensures the glue is evenly distributed within the tank, resulting in better fixation of all parts of the filter, ensuring filter quality, and extending its lifespan.

[0059] This invention discloses a glue injection device and a glue injection method.

[0060] Reference Figures 1 to 4 The glue dispensing equipment includes a support frame 1, a mounting plate 2, a clamping assembly 3, a rotary extrusion mechanism 4, a glue dispensing head 5, and a drive assembly 6. The mounting plate 2 is movably connected to the support frame 1 and has an inclined state and a vertical state. The clamping assembly 3 is disposed on the mounting plate 2 and is used to clamp the filter 7. The rotary extrusion mechanism 4 is disposed on the mounting plate 2 and is used to extrude the filter 7 to expose the glue groove 71 and drive the filter 7 to rotate. One end of the glue dispensing head 5 is used to communicate with the glue dispensing equipment, and the other end is used to correspond to the glue groove 71 of the filter 7. The drive assembly 6 is connected to the mounting plate 2 to drive the mounting plate 2 to switch between the inclined state and the vertical state. In the inclined state, the glue dispensing head 5 corresponds to the filter 7 to dispense glue into the filter 7. In the vertical state, the filter 7 is upright to make the glue evenly distributed.

[0061] Specifically, the outer casing 72 of the filter 7 is cylindrical, closed at the top and open at the bottom. The outer wall of the casing 72 is rolled inward into a J-shaped edge, with the inner side of the rolled edge serving as a glue groove 71. An end cap 73, a filter element 74, and a spring 75 are arranged inside the casing 72, arranged sequentially from bottom to top. The edge of the end cap 73 can be inserted into the glue groove 71.

[0062] The support frame 1 can be formed into a cube by multiple plate-like structures, and weight-reducing holes can be opened on its sides to reduce the overall weight of the support frame 1. The bottom of the support frame 1 can be fixed to the corresponding operating platform 8, and the interior of the operating platform 8 can be used to arrange various components. A protective frame 81 can also be set on the operating platform 8, and a protective plate (not shown in the figure) can be set on the protective frame 81 to cover the entire dispensing equipment. An operating panel 82 can also be set on the protective frame. The operating panel 82 is communicatively connected to the controller, and the controller is communicatively connected to the dispensing equipment. The operator can send commands to the controller through the operating panel 82, and the controller can control the operation of the dispensing equipment according to the commands.

[0063] An inclined mounting surface 11 is provided on the upper side of the support frame 1. The mounting plate 2 is hinged to the lower edge of the mounting surface 11 via a hinge. The drive component 6 is located inside the support frame 1 and connected to the side of the mounting plate 2 away from the hinge, so as to drive the mounting plate 2 to rotate, so that the mounting plate 2 can switch between an inclined state and a vertical state. The specific inclination angle can be designed according to the actual size of the filter 7 and the requirements for glue injection. This invention does not limit it.

[0064] The clamping assembly 3 is located on the side of the mounting plate 2 away from the support frame 1, and is positioned in the middle of the mounting plate 2. The outer wall of the filter 7 is rotatably fitted with the clamping assembly 3. The rotary pressing mechanism 4 can press from both the upper and lower ends of the filter 7 to push the end cap 73 to slide into the interior of the housing 72 and disengage it from the glue tank 71. The glue injection head 5 can be located inside or outside the support frame 1, depending on the actual installation space, as long as it can inject glue into the glue tank 71.

[0065] By clamping the filter 7 onto the inclined mounting plate 2 using the clamping assembly 3, the filter 7 is positioned at a certain tilt angle. Then, the rotating extrusion mechanism 4 extrudes the filter 7 into the glue tank 71. Glue is then injected into the glue tank 71 through the injection head 5. During the injection process, the rotating extrusion mechanism 4 continuously rotates the filter 7, ensuring that the glue tank 71 is evenly filled with glue. After injection, the driving assembly 6 drives the mounting plate 2 to a vertical position, placing the filter 7 upright. The glue then flows evenly into the glue tank 71 under its own weight. This glue injection equipment, when injecting glue into the filter, first assembles the filter, then extrudes the glue tank 71 and rotates the filter 7 to evenly inject the glue into the tank. When the filter 7 is upright, the glue is evenly distributed in the glue tank 71, and the various parts of the filter 7 form a stable connection, ensuring the quality of the filter 7 and extending its service life.

[0066] Optionally, the rotary pressing mechanism 4 includes a sliding plate 41, a pressing head 42, a support head 43, and a sliding drive member 44. The sliding plate 41 is slidably connected to the mounting plate 2; the pressing head 42 is rotatably connected to the sliding plate 41 and is used to abut against the housing 72 of the filter 7; the support head 43 is disposed opposite to the pressing head 42 and rotatably connected to the mounting plate 2, and is used to abut against the end cap 73 of the filter 7 to push the end cap 73 to move relative to the housing 72 and expose the glue groove 71; the sliding drive member 44 is disposed on the mounting plate 2 and connected to the sliding plate 41 to drive the pressing head 42 closer to the filter 7 via the sliding plate 41.

[0067] Specifically, a slide rail is provided on the side of the mounting plate 2, and the sliding plate 41 is slidably connected to the slide rail via a slider. The slide rail extends in the direction close to the clamping assembly 3. To ensure that the sliding plate 41 is subjected to uniform force, two slide rails are provided, located at the two side edges of the sliding plate 41 respectively. The sliding drive component 44 is fixed to the mounting plate 2, and it can be a double-stroke cylinder, with the piston rod fixedly connected to the sliding plate 41.

[0068] A fixing seat 45 is provided on the side of the sliding plate 41. A pressing head 42 is rotatably connected to the fixing seat 45 on the side near the clamping assembly 3. The pressing head 42 is disc-shaped, and its side near the clamping assembly 3 has a cavity to accommodate the housing 72, so as to facilitate smooth contact with the housing 72. A support seat 21 is provided on the lower side of the mounting plate 2. A support head 43 is rotatably connected to the support seat 21. The support head 43 can be elongated, and its end away from the support seat 21 can extend into the housing 72 through the opening of the housing 72 and abut against the end cap 73. The end of the support head 43 extending into the housing 72 has a frustoconical abutment end to ensure effective contact with the end cap 73.

[0069] After the filter 7 is clamped on the mounting plate 2, the end cap 73 of the filter 7 will abut against the support head 43. Then, the sliding drive 44 is activated, which can drive the sliding plate 41 to move. The sliding plate 41 will push the pressing head 42 against the housing 72 of the filter 7 through the fixed seat 45. As the sliding drive 44 continues to operate, the housing 72 and the end cap 73 will move relative to each other, so that the end cap 73 can be disengaged from the glue groove 71 and exposed smoothly.

[0070] Optionally, the axis of the pressing head 42 is collinear with the axis of the support head 43.

[0071] Specifically, the support head 43 can only rotate, while the pressing head 42 is mounted on the sliding plate 41 via the fixed base 45. The sliding plate 41, constrained by the slide rail, maintains a single sliding direction. Since the end cap 73 detaches from the glue tank 71 during glue injection, and after glue injection, the end cap 73 moves again relative to the outer shell 72 and inserts back into the glue tank 71, aligning the axis of the pressing head 42 with the axis of the support head 43 ensures a high degree of concentricity between the end cap 73 and the outer shell 72. This prevents misalignment during relative movement of the end cap 73 and the outer shell 72, further improving the quality of the filter 7.

[0072] Optionally, the rotary pressing mechanism 4 further includes a rotary drive 46. The rotary drive 46 is connected to the pressing head 42 to drive the pressing head 42 to rotate.

[0073] Specifically, the rotary drive component 46 can be a servo geared motor, whose output end is connected to the pressing head 42 via a coupling to drive the pressing head 42 to rotate. The pressing head 42 is in contact with the filter housing 72, and the friction between the pressing head 42 and the housing 72 allows the filter housing 72 to rotate smoothly. It should be understood that the rotary drive component 46 can also be replaced with other structures, such as a rotary electric cylinder, as long as it can smoothly drive the filter housing 72 to rotate.

[0074] Optionally, the rotary extrusion mechanism 4 further includes a synchronization drive 47. The synchronization drive 47 is connected to the support head 43 for driving the support head 43 to rotate.

[0075] Specifically, a synchronous drive component 47 is fixed on the support base 21. It can be a servo geared motor of the same type as the rotary drive component 46 and connected to the support head 43 through a coupling so that the support head 43 can rotate synchronously with the pressing head 42. This ensures that the end cap 73 can rotate synchronously with the outer shell 72, further ensuring the concentricity of the end cap 73 and the outer shell 72 during the glue injection process.

[0076] Optionally, the mounting plate 2 has an adjustment hole 22, and the glue injection head 5 passes through the adjustment hole 22 and can slide relative to the mounting plate 2.

[0077] Specifically, the aforementioned adjustment hole 22 is formed through the mounting plate 2, located between the clamping assembly 3 and the support base 21. The dispensing head 5 passes through the adjustment hole 22 from the underside of the mounting plate 2 and extends toward the clamping assembly 3. An adjustment assembly is provided inside the support frame 1, comprising a lifting drive 51 and a translation drive 52. The translation drive 52 is connected to the dispensing head 5 to drive the dispensing head 5 toward or away from the filter 7. The lifting drive 51 is connected to the translation drive 52. When the mounting plate 2 is tilted, the lifting drive 51 can push the translation drive 52 to move in a direction perpendicular to the mounting plate 2. The specific configuration of the lifting drive 51 and the translation drive 52 can be designed according to the actual installation space and dispensing requirements. For example, it can be implemented using a servo motor and a transmission structure, or it can be implemented using an electric cylinder or other driving elements. This invention does not limit this.

[0078] By setting the adjustment hole 22, the glue injection head 5 can pass through the adjustment hole 22 and smoothly correspond to the glue tank 71. The position of the glue injection head 5 can be flexibly adjusted by the adjustment component to adapt to filters 7 of different sizes, so that the glue injection equipment can perform glue injection operations on various filters 7, effectively improving the adaptability of the equipment.

[0079] Optionally, the drive assembly 6 includes a drive cylinder 61 and a connecting seat 62. The drive cylinder 61 is rotatably connected to the support frame 1; the connecting seat 62 is disposed on the mounting plate 2 and hinged to the piston rod of the drive cylinder 61.

[0080] Specifically, the cylinder body of the drive cylinder 61 is hinged to the support frame 1, and its piston rod can extend toward the mounting plate 2. The piston rod is rotatably connected to the connecting seat 62 through the adapter block. The connecting seat 62 is fixed on the bottom surface of the mounting plate 2. The fixing method can be bolt connection, welding or bonding, etc.

[0081] When it is necessary to switch the state of the mounting plate 2, the drive cylinder 61 is activated. The piston rod of the drive cylinder 61 extends and pushes the mounting plate 2 to flip through the connecting seat 62. When the mounting plate 2 is in a vertical state, the drive cylinder 61 stops running, so that the mounting plate 2 can be smoothly switched from a tilted state to a vertical state.

[0082] Optionally, the clamping assembly 3 includes a clamping base 31, a clamping member 32, and a roller 33. The clamping base 31 is disposed on the mounting plate 2 and is used to support the filter 7; the clamping member 32 is disposed on the mounting plate 2 and is used to clamp the filter 7 and is rotatably connected to the filter 7. The roller 33 is rotatably connected to the clamping base 31 and abuts against the surface of the filter 7.

[0083] Specifically, the clamping seat 31 can be detachably connected to the mounting plate 2 via bolts or other structures. A recessed receiving groove is provided on the side of the clamping seat 31, and the cross-section of the receiving groove can be V-shaped. Multiple rollers 33 are spaced apart on the groove wall. Two clamping members 32 can be arranged opposite each other, located on opposite sides of the clamping seat 31. The clamping members 32 can be clamping cylinders, with V-shaped clamping ends to facilitate clamping the cylindrical filter 7 and ensure that the filter 7 can rotate.

[0084] When it is necessary to clamp the filter 7, the filter 7 can be placed on the roller 33 of the clamping base 31, and the clamping member 32 can clamp the filter 7 from both sides, so that the filter 7 can be clamped on the mounting plate 2. At the same time, the roller 33 can make the filter 7 rotate during the clamping process to meet the requirements of glue injection.

[0085] Reference Figure 5 This dispensing method is applied to the dispensing equipment described above, and the method includes:

[0086] Step S1: Control the drive assembly 6 to tilt the mounting plate 2, obtain the filter 7, and clamp the filter 7 onto the mounting plate 2 using the clamping assembly 3.

[0087] The tilted state refers to the mounting plate 2 being in a tilted position. At this time, since both the clamping assembly 3 and the rotary pressing assembly are set on the mounting plate 2, the filter 7 after being clamped will be tilted. At this time, the opening of the glue groove 71 formed by the rolled edge inside the filter 7 will tilt upward.

[0088] Step S2: Control the rotating extrusion mechanism 4 to extrude the filter 7 to expose the glue tank 71.

[0089] The filter 7 includes a housing 72 and an end cap 73 disposed inside the housing 72. One side of the end cap 73 can be inserted into the glue tank 71, and the other side is provided with a filter element 74 and a spring 75. The rotary pressing mechanism 4 abuts against the end cap 73 and the housing 72 respectively. By pressing the end cap 73 to move relative to the housing 72, the end cap 73 can be disengaged from the glue tank 71, thereby smoothly exposing the glue tank 71.

[0090] Step S3: Align the glue injection head 5 with the glue tank 71 of the filter 7 and inject glue, and control the rotary extrusion mechanism 4 to drive the filter 7 to rotate.

[0091] After the glue tank 71 is exposed, the glue injection head 5 can be moved so that the glue injection head 5 corresponds to the glue tank 71. The rotating extrusion mechanism 4 can drive the outer shell 72 of the filter 7 to rotate, so that the glue can be evenly injected into various parts of the glue tank 71 during the glue injection process. Since the glue has poor fluidity, the rotating outer shell 72 will not cause the glue to leak.

[0092] Step S4: After the glue is applied, separate the glue head 5 from the filter 7 and control the drive assembly 6 to switch the mounting plate 2 to a vertical position so that the filter 7 is upright and the glue is evenly distributed in the glue tank 71.

[0093] After the glue is applied, the mounting plate 2 is switched to a vertical position. During the switching process, the rotary extrusion mechanism 4 continues to extrude the filter 7, and the glue will flow evenly into the glue tank 71 under its own weight. When the rotary extrusion mechanism 4 gradually releases, the end cap 73 of the filter 7 will continue to abut against the support head 43, and the pressing head 42 will gradually separate from the outer shell 72. Under the action of the spring 75 inside the outer shell 72, the outer shell 72 will be driven to move relative to the end cap 73, and the end cap 73 can be inserted into the glue tank 71.

[0094] Through the aforementioned steps S1, S2, S3, and S4, the glue tank 71 can be exposed during glue injection, allowing the glue to quickly enter the glue tank 71 and thus rapidly completing the glue injection process, improving injection efficiency. During the glue injection process, the filter 7 can be tilted and rotated first, allowing the glue to be evenly injected into the glue tank 71. Then, by verticalizing the filter 7, the glue can be evenly distributed within the glue tank 71, resulting in better fixation of each part of the filter 7, ensuring the quality of the filter 7, and extending its service life.

[0095] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
