[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] The invention discloses a filter end cover transfer and positioning mechanism, which is mainly used for transfer between tapping and feeding stations in automatic tapping equipment and for positioning the transferred filter end cover to prevent the filter end cover from rotating synchronously with the tapping mechanism during rotation.

[0038] The transfer and positioning mechanism includes a transfer platform 1000, which is fixed on a frame 4000. A transfer station and a tapping station are set at the front and rear ends of the transfer platform. The transfer station can be fed by a robot or other feeding methods. A transfer mechanism 100 and a positioning mechanism 200 are set at the bottom of the transfer platform. By utilizing the cooperation between the positioning mechanism and the transfer mechanism, when the transfer mechanism moves to the tapping station, the positioning mechanism can rotate to make room, and when the transfer mechanism returns, the positioning mechanism is reset and the filter end cover is positioned.

[0039] The transfer platform 1000 has one end configured as a transfer station for the clamping mechanism 300 to place the filter end cover 2000, and the other end configured as a tapping station 40 for the tapping mechanism 400 to perform tapping operations on the filter end cover 2000.

[0040] like Figure 1 and Figure 2 As shown, a transfer table 1000 is provided between the second transfer station and the tapping station. The transfer table 1000 is a part of the working table, which is mainly used for the transfer support of the filter end cover on its surface. A plurality of parallel grooves 1100 are provided on the transfer table, which connect the second transfer station and the tapping station, and are used for the fingers of the transfer mechanism to pass through the transfer table and drive the filter end cover located on the transfer table to move, thereby having the function of guiding and avoiding.

[0041] The width of the narrow section 1110 is smaller than the outer diameter of the protrusion of the filter end cover 2000 , and the width of the wide section 1120 is larger than the outer diameter of the protrusion of the filter end cover 2000 .

[0042] A gasket 1200 is provided at the second transfer station to play a buffering role and prevent the protruding part of the filter end from being embedded in the groove. At the same time, the clamping mechanism places it on the gasket, and the entire filter end cover is slightly higher than the transfer table to avoid always moving in contact with the transfer table when being driven by the transfer mechanism, causing wear to the filter end cover or the transfer table.

[0043] The transfer mechanism 100 is arranged on the lower side of the transfer platform 1000 and can move between the transfer station and the tapping station 40. When the transfer mechanism 100 moves to the tapping station 40, it drives the filter end cover 2000 at the transfer station to enter the tapping station 40 and ejects the filter end cover 2000 originally located in the tapping station 40.

[0044] like Figure 3As shown, the transfer mechanism 100 is arranged below the second transfer station 30 and is used to drive the filter end cover 2000 to be transferred from the second transfer station 30 to the tapping station 40.

[0045] like Figure 4 As shown, the transfer mechanism 100 includes a linear guide 110, a mounting seat 120, a lifting plate 130 and a clamping assembly 140. The transfer mechanism 100 mainly drives the mounting seat to slide relative to the linear guide through a power source such as a motor, thereby driving the lifting plate arranged on the mounting seat to move synchronously, and the lifting plate is lifted and lowered through a power source such as a cylinder, thereby forming a clamping fit between the clamping assembly and the filter end cover. In the present application, the clamping assembly is preferably a finger cylinder, and corresponding finger-shaped claws are arranged on its two driving ends, which are inserted into the central circular hole of the filter and opened to achieve clamping, thereby driving the filter end cover to move synchronously.

[0046] The linear guide rails 110 are arranged along the transmission direction of the filter end cover 2000 and are arranged on both sides below the transfer table.

[0047] The mounting seat 120 forms a sliding fit with the linear guide rail 110, and its two ends are provided with sliders that slide with the linear guide rail 110. The mounting seat is a plate-like structure, and its two ends are fixed below the slider, and the top is used to install a power source such as a motor or a cylinder.

[0048] The lifting plate 130 can be raised and lowered above or below the mounting seat 120. In the present embodiment, the lifting plate is arranged below the mounting seat. There are two lifting plates symmetrically arranged at both ends of the mounting seat 120, and they cooperate with the guide sleeves on the mounting seat through a plurality of guide rods. At the same time, the lifting plate is driven to rise or fall accordingly by a power source arranged on the mounting seat. At the same time, the projection area of ​​the lifting plate is larger than the projection area of ​​the mounting seat, which is the area projected by the two on the transfer table. Therefore, the clamping assembly 140 can be arranged at the position of the lifting plate not covered by the mounting seat.

[0049] A plurality of clamping assemblies 140 are arranged on the lifting plate 130. The clamping assemblies are a plurality of finger cylinders arranged at intervals on the lifting plate and finger-shaped claws driven by the finger cylinders. This structure is a conventional mechanism, such as Figure 4 As shown, no detailed description is given.

[0050] The specific working process is as follows: when the clamping mechanism moves the filter end cover to the second transfer station, the clamping assembly rises under the drive of the lifting plate, and the finger-shaped claw is inserted into the center hole of the filter end cover and clamped, and then the clamping mechanism drives it to move to the tapping station. Since the groove in the initial position is slightly narrow, the filter end cover is located above the transfer table as a whole, and a gap is made between the filter end cover and the transfer table by relying on the gasket, so that when the filter end cover is driven to move, the filter end cover moves in mid-air. After moving a certain distance, that is, when it is close to the tapping station, it enters the wide part of the groove, and the second lifting plate descends to fit the filter end cover with the transfer table and drive it to continue moving forward, and the latter is used to impact the filter end cover located in the tapping station and send it to the discharge station. Preferably, a pressing plate 1300 is provided on the tapping station to press the filter end cover during tapping to prevent the pin of the positioning mechanism below from lifting the filter end cover.

[0051] The positioning mechanism 200 is arranged on the lower side of the transfer platform 1000 and is located below the tapping station 40. The positioning mechanism 200 includes a first position with a vertical filter end cover 2000 transmission path and a second position that allows the transfer mechanism 100 to move to directly below the tapping station 40 by rotation.

[0052] like Figure 3 As shown, in this embodiment, a positioning mechanism 200 is further provided below the tapping station. The positioning mechanism 200 has a first position perpendicular to the filter end cover transmission path and an inclined setting to allow the transfer mechanism 100 to move to a second position directly below the tapping station 40.

[0053] The positioning mechanism 200 can release the second position by rotation or by linear movement.

[0054] like Figure 5 As shown, the positioning mechanism 200 includes a fixed arm 210 and a rotating arm 220. The fixed arm is fixed below or on both sides of the transfer table. A rotating shaft is provided at one end away from the transfer table. The rotating arm 220 can be rotatably arranged with the fixed arm through the rotating shaft. A fixed plate 230 is provided at the other end of the rotating arm. The fixed plate connects the rotating arms on both sides. The fixed plate 230 is also provided with a power source 260 for driving the rotating arm to rotate relative to the rotating shaft, such as a cylinder. The fixed plate 230 is also provided with a movable plate 240 arranged parallel to the fixed plate. The movable plate is connected to the fixed plate through a guide rod and a guide sleeve. At the same time, the fixed plate 230 is provided with a driving cylinder for driving the movable plate to move relative to the guide rod or the guide sleeve.

[0055] The movable plate is provided with a plurality of spaced limit seats 250 along the length direction, and limit blocks are provided on both sides of the limit seats. A detachable positioning member 270 is provided in the limit seat 250, and the positioning member slides in from both sides of the limit block and is fixed by bolts. A positioning hole is provided at the upper end of the positioning member, and a pin needle 280 is provided in the positioning hole.

[0056] The specific workflow is as follows: When the transfer mechanism is feeding, the positioning mechanism rotates away from the transfer mechanism under the drive of the cylinder, thereby making room for the space below the tapping station. The transfer mechanism moves normally to the bottom of the tapping station and delivers the filter end cover to the tapping station, and then the transfer mechanism returns to the second transfer station. At the same time, the positioning mechanism returns to the center, and the positioning piece is placed directly below the tapping station, and then the cylinder is driven to drive the movable plate to move upward. At this time, the pin needle supports the filter end cover, and driven by the rotating force of the tapping mechanism, the filter end cover rotates synchronously, and when the holes around it are aligned with the pin needle, the pin needle is inserted into the corresponding hole under the action of the spring, and the filter end cover is hung, thereby limiting the rotation of the filter end cover, so that the tapping mechanism can perform tapping operations on the filter end cover.

[0057] The present invention also discloses an automatic tapping device for a filter end cover, which is mainly used for the automatic tapping of the filter end cover, wherein the device integrates an automatic feeding mechanism for the filter end cover and an automatic tapping mechanism for the filter end cover, thus realizing the whole process of feeding-transferring-tapping-discharging the filter end cover, eliminating the tediousness of the previous need for multiple devices to cooperate, and the multi-purpose use of one machine can reduce the demand for the operating area.

[0058] like Figure 6 As shown, the filter end cover automatic tapping device includes a frame 4000 constructed of steel material and a shell 3000 covering the entire frame 4000, as shown in FIG. Figure 6 As shown, the coordinate axis X direction is used as the transmission direction of the filter end cover 2000, the Y direction is the transmission direction of the discharge mechanism, and the Z direction is the lifting direction.

[0059] like Figure 7 As shown, the frame 4000 is provided with a first transfer station 10, a flipping station 20, a second transfer station 30, a tapping station 40 and a discharging station 50 in sequence along the transmission direction of the filter end cover 2000, wherein the first transfer station 10 is used for temporary storage of the filter end cover feeding, the flipping station 20 is used for identifying the front and back sides of the filter end cover and performing unified operations on the front and back sides, the second transfer station 30 is used for temporary storage of the flipped filter end cover, and the tapping station is used for tapping the filter end cover, and the discharging station is used for discharging the filter end cover after tapping, which are arranged in sequence along the X direction, so that the entire equipment is more reasonable and the overall structure is relatively compact.

[0060] like Figure 8 As shown, the frame 4000 has a work surface, and the transfer surface is also a part of the work surface. The frame is provided with a feeding mechanism 500, a clamping mechanism 300, a detection unit 700, a flipping mechanism 600, a lifting mechanism 800, a transfer mechanism 100, a tapping mechanism 400 and a discharging mechanism 5000. The feeding mechanism 500 is arranged at the first transfer station, and the lifting mechanism, the flipping mechanism and the detection unit are arranged at the flipping station. At the same time, the three are arranged from bottom to top along the Z direction in a straight line, so that the detection unit located above can detect the front and back sides of the filter end cover arranged on the lifting mechanism. The clamping mechanism is arranged to move along the X axis, and it can move between the first transfer station, the flipping station and the second transfer station, that is, the filter end cover is moved from the first transfer station to the flipping station and the filter end cover is moved from the flipping station to the second transfer station, and it can also move from the flipping station to the first transfer station or the second transfer station or move in the opposite direction. The transfer mechanism 100 can move along the X-axis. It is arranged between the second transfer station, i.e., the tapping station, and reciprocates to transfer the filter end cap from the second transfer station to the tapping station. In this embodiment, the transfer mechanism is arranged below the work surface, and the clamping mechanism is arranged above the work surface. The two are arranged alternately to avoid interference in movement. At the same time, the transfer mechanism arranged below can also avoid the tapping mechanism, so that the tapping mechanism only needs to move in the Z direction and perform rotary tapping. The discharging mechanism 5000 is arranged at the discharging station to receive the filter end cap that has completed tapping and transport it out.

[0061] like Fig.13 As shown, the feeding mechanism 500 is mainly used to move the filter end cover 2000 to the first transfer station 10. It is mainly used to cooperate with the feeding trolley. It includes a lifting plate 510. It is driven by a plurality of parallel linear guide rails and a screw rod 520. The lifting plate and the screw rod structure cooperate with each other to drive the lifting plate to move upward, thereby driving the filter end cover mounted on the feeding trolley 6000 to be lifted piece by piece. The linear guide rail is used for guidance. The specific structure of the feeding trolley and its cooperation with the equipment can refer to the Chinese patent CN218431348U previously applied by the applicant, which specifically discloses the specific structure of the filter cover (filter end cover) loading trolley and its cooperation structure with the automatic feeder. The feeding trolley used in this application is consistent with the Chinese patent previously applied for, so this application will not elaborate on it.

[0062] like Figure 8 and Fig.11 As shown, the clamping mechanism 300 is disposed above the first transfer station 10 for clamping the filter end cover 2000 , and can move between the first transfer station 10 , the flipping station 20 and the second transfer station 30 .

[0063] The clamping mechanism 300 includes a linear guide rail, a first mounting seat 320 , a first lifting plate 330 and a first clamping mechanism 310 .

[0064] The linear guide rail is arranged along the transmission direction of the filter end cover 2000. There are two linear guide rails, which are symmetrically arranged on both sides of the frame, and their linear directions are arranged in the X-axis direction, so that the first mounting seat matched with it can slide along the linear guide rail as a whole to ensure the consistency of direction; The first mounting seat 320 forms a sliding fit with the linear guide rail, and the length direction of the mounting seat is the Y direction, that is, it is arranged across the entire frame, and sliders compatible with the linear guide rail are arranged on both sides thereof. The first mounting seat is a plate-like structure, and its two ends are fixed to the sliders through support frames, and the front and rear surfaces of the first mounting seat are mounting surfaces, and then by arranging a first lifting plate on the side facing the second transfer station, the first clamping mechanism arranged thereon can move along the Z-axis direction.

[0065] The movement of the first mounting seat can be driven by a motor and a conveyor belt.

[0066] The first lifting plate 330 can be slidably set on the first mounting seat 320, and the sliding cooperation between the first lifting plate and the first mounting seat is realized through a plurality of linear guide rails. The first lifting plate is driven to move along the Z direction by a power source such as a cylinder or a motor, thereby causing the first clamping mechanism to move downward or upward.

[0067] A plurality of first clamping mechanisms 310 are arranged on the first lifting plate 330. The first clamping mechanisms 310 can clamp the filter end cover when descending, thereby driving the filter end cover to move.

[0068] like Fig.12 As shown, the first clamping mechanism 310 includes a first fixing seat 311, a first power source 312, a magnetic member and a plurality of limit rods 314. In this embodiment, the first clamping mechanism uses a magnetic attraction method to adsorb the filter end cover.

[0069] The first fixed seat 311 is fixedly connected to the first lifting plate 330 for supporting the first clamping mechanism, and is provided with a relatively movable push rod, the push rod portion is arranged inside the first fixed seat 311, and forms a limit fit with the first fixed seat 311 with a certain amount of sliding, and a spring is provided on the outer sleeve of the push rod. The design of the spring achieves a buffering effect, that is, when the first clamping mechanism moves downward and touches the filter cover, it can be buffered by the spring so that it has a certain amount of deformation, thereby avoiding the hard top filter cover, resulting in excessive resistance of the first clamping mechanism and causing damage.

[0070] The first power source 312 is connected to the first fixed seat 311. The first power source 312 adopts a cylinder, which has a movable rod. The movable rod has a state change of extending and retracting. The rear end of the first power source is fixedly connected to the push rod so that the movable amount of the push rod can be utilized.

[0071] The magnetic member 313 may be a magnet directly, and is fixedly connected to the movable rod of the first power source 312 .

[0072] A plurality of limit rods 314 are disposed at the front end of the first power source 312 and are circumferentially arranged around the magnetic member 313 , and the length of the limit rods 314 is greater than or equal to the maximum moving distance of the magnetic member 313 .

[0073] At the same time, a groove is provided at the position where the magnetic part cooperates with the limiting rod, and the limiting rod is arranged through the groove. In some embodiments, a through hole can also be directly provided on the magnetic part, and the limiting rod is arranged through the through hole, so that the limiting rod plays a guiding role.

[0074] At the same time, the limit rod first presses against the circumference of the filter end cover, and then drives the magnetic part to descend through the first power source 312, so that the magnetic force of the magnetic part adsorbs the filter end cover and clamps it. When the magnetic part is driven to rise, since the limit rod restricts the filter end cover, the movement of the magnetic part will not drive the filter end cover to move synchronously. Then, when the magnetic part leaves the filter end cover for a certain distance, since the magnetic force at this time is not enough to adsorb the filter end cover, the filter end cover will fall on the corresponding workstation, thereby completing the transfer of the filter end cover.

[0075] In other embodiments, the first clamping mechanism may also adopt a finger cylinder, which utilizes the opposite movement of the claws to clamp the outer periphery of the filter end cover, thereby playing a clamping role. At the same time, a three-claw or two-claw method may also be used, which is inserted into the center of the filter end cover and opened outward for fixation. The fixing method can be diversified and can be selected according to needs.

[0076] like Figure 8 As shown, the detection unit 700 is located above the flipping station 20, and is used to detect the front and back states of the filter end cover 2000 located at the flipping station 20, and output a control signal. The detection unit can use a camera or a camera, which is fixed above the flipping station through a bracket. It recognizes the detected image through the central control machine. When it recognizes that the filter end cover with inconsistent front and back sides is identified, it outputs a control signal corresponding to the flipping mechanism to control it to flip 180°.

[0077] like Fig. 9 and Fig.10 The flipping mechanism 600 is disposed at the flipping station 20, and according to the received control signal, the filter end cover 2000 with non-uniform surface is clamped and flipped 180 degrees.

[0078] The flipping mechanism 600 comprises: The clamping jaws 610 are arranged facing each other, and a clamping position is formed between the two clamping jaws 610. The clamping position is circular or composed of two trapezoidal clamping openings or two V-shaped clamping openings, so as to clamp the filter end cover from the outer periphery of the filter end cover; A driving assembly 620 is used to drive the two claws 610 to move toward or in opposite directions. The driving assembly 620 can be a finger cylinder, which is often used to drive the claws to move; The rotating assembly 630 adopts a rotating cylinder, which is fixed on the frame and is used to drive the driving assembly to rotate 180 degrees.

[0079] The specific working process is as follows: the two claws are driven by the driving assembly to move toward each other and clamp the filter end cover, and then according to the control signal, the rotating assembly at the supporting position of the filter end cover with non-uniform surfaces is controlled to rotate 180° to complete the unification of the front and back sides of the filter end cover.

[0080] The lifting mechanism 800 is disposed below the flipping mechanism 600 and is used to carry the filter end cover 2000 moved from the first transfer station 10 to the flipping station 20, and has a first position for rising to carry the filter end cover 2000 and a second position for falling to avoid the flipping mechanism 600.

[0081] The lifting mechanism 800 includes a support plate 810, both ends of which are provided with lifting components 820 for driving the support plate 810 to switch between a first position and a second position, and the upper surface of the support plate 810 is provided with a plurality of support components 830 spaced apart along the length direction of the support plate 810.

[0082] The lifting assembly 820 adopts a cylinder, which uses the extension and retraction of a movable rod to achieve the lifting and lowering action of the support plate.

[0083] The support assembly is a support ring, which is arranged slightly higher than the support plate 810. When the filter end cover is placed on the support ring, the outer periphery of the filter end cover is in a suspended state, which is convenient for clamping by the claws. The diameter of the support ring is adapted to the diameter of the middle protruding position of the filter end cover.

[0084] The support ring can be replaced as required to adapt to the support of filter end covers of different sizes.

[0085] In order to better position the support ring, a positioning groove 840 is provided on the support plate, and the support ring is embedded in the positioning groove to ensure that its position will not be offset.

[0086] The specific working process is as follows: the claws are in an open state, the filter end cover is clamped by the clamping assembly and moved to the flipping station, the support plate moves upward, the filter end cover is placed on the support plate, the clamping assembly avoids, and then the detection unit detects the front and back sides of the filter end cover, and then the flipping mechanism clamps the filter end cover, the support plate moves downward to avoid the flipping mechanism, and then the corresponding flipping mechanism flips, the support plate moves upward, the flipping mechanism releases the filter end cover, and then the clamping mechanism moves to the flipping station, and then the clamping mechanism transfers the filter end cover. In other embodiments, the filter end cover can also be clamped by the flipping mechanism, and then the front and back sides can be detected by the detection unit.

[0087] The tapping mechanism 700 is disposed at the tapping station 40 and performs a tapping operation on the filter end cover 2000 located at the tapping station 40 .

At the same time, a magnet 7300 with a through hole is provided in the oil return port 7200. Even if metal chips accumulate and enter the oil return hole, they will be absorbed by the magnet 7300 to ensure that the metal chips will not enter the oil return hole. The through hole of the magnet 7300 is compatible with the oil return hole 7400 to ensure the normal use of the oil return hole.

[0099] See also Fig.17A discharge slope 60 is provided between the discharge mechanism and the tapping station. The discharge slope 60 is provided with a plurality of oil holes and is located above the oil return tank, so that the residual liquid on the filter end cover can directly enter the oil return tank through the oil holes. An oil return plate 61 is also provided at the bottom of the discharge slope. One end of the oil return plate is located at the bottom of the oil hole, and the other end extends to the top of the oil return tank, ensuring that all liquid can return to the oil return tank, making the interior cleaner. At the same time, in order to accelerate the dripping of the residual liquid on the filter end cover, a position-adjustable blower mechanism 900 is provided at the discharge station 50. The blower 900 can be adjusted to align the air outlet with the discharge slope 60, and use wind force to blow away the liquid on the filter end cover.
