Description

Technical Field

[0001] The present invention particularly relates to an automatic filter leak tester. Background Art

[0002] Sliding door and window locks are used to lock and open sliding doors and windows. At present, the most commonly used locks for sliding doors and windows are hook locks. Depending on the size of the sliding doors and windows, some locks have only one hook lock, and some locks have at least two hook locks. Multiple hook locks increase the locking points of the sliding doors and windows, and the locking is more secure.

[0003] The existing hook lock for sliding doors and windows mainly includes a shell and a transmission mechanism arranged in the shell, the transmission mechanism is linked with a lock tongue assembly, and the transmission mechanism is mainly composed of a driving gear, two driving bars and two lock components arranged in the shell. The handle or key passes through the shell and is connected to the driving gear shaft, the driving bar is toothed with the driving gear, and the lock component is fixedly connected to the driving bar; therefore, turning the handle or key causes the driving gear to rotate, and the rotation of the driving gear drives the planar displacement of the driving bar, and the planar displacement of the driving bar causes the fixedly connected lock component to be locked or opened; the slave hook lock is hooked with the main hook lock through a pull rod, so that the main hook lock drives the slave hook lock to be locked or opened.

[0004] However, the hook locks for sliding doors and windows in the prior art have complex structures, numerous parts, and small internal parts, which are inconvenient to take manually, resulting in cumbersome installation and low assembly efficiency. Gear transmission is generally used. Although gear transmission has good transmission stability, the gear ratio must be reasonably allocated during the design and assembly process, and the gear must be processed according to the corresponding transmission ratio. However, gear production is not easy, and purchasing in large quantities increases the manufacturing cost of the hook lock, which is not economical. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an automatic filter leak tester in view of the deficiencies of the above-mentioned prior art. Through the automatic sorting function, the equipment reduces the number requirements of the double-station leak test stations, flipping mechanisms and filter transfer devices. It only needs to increase the stations for clamping the filters, thereby reducing the equipment cost and reducing the equipment size.

[0006] To achieve the above object, the present invention provides the following technical solutions: The automatic filter leak detection machine comprises a frame, an automatic sorting and unloading device, and an air tightness detection device. An automatic unloading conveyor belt is arranged between the automatic sorting and unloading device and the air tightness detection device. A filter transfer device is arranged above the automatic unloading conveyor belt. The air tightness detection device comprises a water tank, at least two groups of detection clamping tooling and a flipping mechanism linked to the detection clamping tooling; the automatic sorting and unloading device comprises a conveyor belt and a left opening and closing plate and a right opening and closing plate relatively distributed on both sides of the conveyor belt, and pulleys are respectively linked at both ends of the conveyor belt, and the pulleys are linked with a second servo motor, characterized in that: the left opening and closing plate is located on a side facing the right opening and closing plate and is provided with a plurality of groups of left push blocks spaced apart from each other, the right opening and closing plate is located on a side facing the left opening and closing plate and is provided with a group of right material accommodating grooves corresponding to each group of left push blocks, a group of left accommodating grooves are arranged between each two adjacent groups of left push blocks, and a group of right push blocks are arranged between each two adjacent groups of right material accommodating grooves; when the left opening and closing plate and the right opening and closing plate are close to each other, each group The corresponding left push block and the right material containing groove form a group of first column sorting grooves, and each group of right push block and the left material containing groove form a group of second column sorting grooves, and the first column sorting grooves and the second column sorting grooves are staggered with each other; a mounting frame is provided below the conveyor belt, and a plurality of groups of screw rods are hinged on the mounting frame, and the upper part of the screw rod is provided with a first section of thread, and the lower part is provided with a second section of thread, and the first section of thread and the second section of thread are symmetrical to each other. The screw rod is linked with a left nut sleeve through the first section of thread, and the screw rod is linked with a right nut sleeve through the second section of thread, and the left nut sleeve is linked with a left slider, and the right nut sleeve is linked with a right slider, the left slider is linked with the left opening and closing plate, and the right slider is linked with the right opening and closing plate, and a first slide rail is fixed on the mounting frame, and the left slider and the right slider are respectively slidably matched with the first slide rail; the end of the screw rod is linked with a driven pulley, and the driven pulley is linked with a belt, and the belt is linked with a driving pulley, and the driving pulley is linked with a first servo motor fixed on the mounting frame.

[0007] When the equipment is started, the filter is transported through the conveyor belt. When the filter reaches the specified position, the second servo motor drives the pulley to rotate, thereby driving the conveyor belt to stop or slow down. Then the first servo motor starts to drive the active pulley to rotate. The active pulley transmits power to the driven pulley through the belt, and the driven pulley is linked with the end of the screw rod to drive the screw rod to rotate. The screw rod is provided with a first section of thread and a second section of thread that are symmetrical to each other. As the screw rod rotates, the left nut sleeve moves upward on the first section of thread, and the right nut sleeve moves downward on the second section of thread (or moves in the opposite direction, depending on the rotation direction of the screw rod). The left nut sleeve and the right nut sleeve can move synchronously but in opposite directions. The left nut sleeve is linked with the left slider, and the right nut sleeve is linked with the right slider. As the nut sleeve moves, the left slider and the right slider slide on the first slide rail respectively, thereby driving the left opening and closing plate and the right opening and closing plate to be relatively close or separated. When the left opening and closing plate and the right opening and closing plate are relatively close, the first row of sorting slots is gradually formed between the left push block and the right material storage slot, and the second row of sorting slots is gradually formed between the right push block and the left material storage slot. The filters are accurately pushed into these sorting slots to achieve automatic sorting and sorting of the filters, reducing the number of double-station leak detection stations, flipping mechanisms and filter transfer devices required by the equipment. Only the corresponding stations for clamping the filters need to be added, which reduces the equipment cost and minimizes the equipment size.

[0008] The above-mentioned automatic filter leak tester can be further configured as follows: the feed end of the conveyor belt is provided with a turntable and a turntable driving mechanism for driving the turntable to rotate, the turntable is provided with several groups of clamping mechanisms along the circumference, a cam is hinged in the middle of the turntable, a pushing block is provided between the clamping mechanism and the cam, the turntable driving mechanism can drive the turntable to rotate around the cam, the turntable is provided with a group of slide grooves corresponding to each group of pushing blocks, a first sliding block adapted to the slide groove is linked below the pushing block, one end of the pushing block keeps in contact with the outer peripheral surface of the cam, and the other end extends to the middle of the clamping mechanism, pushing inclined surfaces are symmetrically provided on both sides of the pushing block, the clamping mechanism includes two groups of symmetrically distributed clamping jaws, one end of each group of clamping jaws extends to the pushing inclined surface, and the middle part is hinged on the turntable, and each group of clamping jaws is linked with a group of elastic reset Mechanism, the elastic reset mechanism includes a spring seat fixed on the turntable, the spring seat is located at the side facing the clamping jaw and is provided with a first mounting hole, a clamping jaw reset spring is arranged in the first mounting hole, the end of the clamping jaw reset spring is linked with a pushing pin, a guide strip is arranged between one end and the middle of the clamping jaw, and the pushing pin is kept in contact with the guide strip under the push of the clamping jaw reset spring; one end of the pushing block is hinged with a first roller, the first roller is in rolling contact with the outer peripheral surface of the cam, the outer peripheral surface of the cam is provided with at least one group of protrusions, the two ends of the protrusions are connected with the cam at the connection points, the end of the protrusion is provided with a first limit block fixed on the cam, and the upper part of the pushing block is linked with a second limit block; one end of the clamping jaw is hinged with a second roller, and the second roller is in rolling contact with the pushing inclined surface.

[0009] When the turntable driving mechanism drives the turntable to rotate, one end of the push block contacts the outer peripheral surface of the cam (this is mainly because the jaw reset spring always pushes the jaw, causing the end of the jaw to always contact the push inclined surface, exerting a resistance force on the push block). As the shape of the cam changes, the push block is pushed and slides along the slide groove. When the push block slides along the slide groove, its push inclined surface will push the jaw, causing the jaw to rotate around its center to achieve opening and closing actions, reducing the number of driving sources. The entire turntable manipulator only needs one turntable driving mechanism to drive the movement of the entire turntable and all jaw mechanisms, greatly reducing the structural complexity and manufacturing cost. Furthermore, since there are protrusions on the periphery of the cam, a first limit block is designed above a group of protrusions, and a second limit block is designed above the push block, the purpose is to prevent the jaw from opening prematurely. Only when the jaw reaches the predetermined position can it be opened, so as to achieve rapid material discharge and clamping, and prevent the filter from falling or sliding out. In summary, all the actions of the clamping mechanism are performed simultaneously during the rotation of the turntable, without waiting for the previous action to be completed before the next action is performed, thereby significantly improving the work efficiency. Among them, the slide groove and the first slider are provided so that the push block can slide smoothly along the radial direction of the turntable without offset or jamming, thereby ensuring the accuracy and stability of the opening and closing action.

[0010] The above-mentioned automatic filter leak detection machine can be further configured as follows: the turntable is provided with a material passing opening slot corresponding to each group of clamping jaw mechanisms, a feed plate is provided at one group of material passing opening slots, the feed plate is penetrated by a strip-shaped detection hole, an incoming material sensor is installed at the strip-shaped detection hole, the incoming material sensor is fixed on the bracket, a second slider is fixedly installed on the bracket, the second slider is slidably connected to a second slide rail, the second slide rail is fixed under the feed plate, and a plurality of groups of fastening nail holes are provided on the second slide rail.

[0011] A material opening slot is provided to facilitate the filter to enter the turntable. A feed plate and an incoming material sensor are added to detect the presence or position of the filter. Once detected, the turntable starts to work. The incoming material sensor is fixed on the bracket, and the bracket is slidably connected to the second slide rail through the second slider. The second slide rail is fixed under the feed plate and is provided with a plurality of sets of fastening nail holes for adjusting the position of the incoming material sensor.

[0012] The above-mentioned automatic filter leak tester can be further configured as follows: a second mounting hole is passed through the middle of the turntable, a bearing is arranged in the second mounting hole, the bearing is linked to a mounting shaft, a conical connecting column is provided at the upper end of the mounting shaft, connecting holes are provided at the middle of the cam and the upper end of the conical connecting column, a first strip-shaped pin groove is provided at the outer periphery of the conical connecting column, a conical plug-in hole adapted to the conical connecting column is provided below the cam, a second strip-shaped pin groove is provided on the side wall of the conical plug-in hole corresponding to the first strip-shaped pin groove, and the second strip-shaped pin groove passes through the cam.

[0013] A bearing is arranged in the second mounting hole to realize "the turntable rotates around the cam, while the cam is fixed". The mounting shaft is used to install the cam. Conical connecting columns and conical connecting holes are added to adapt to cams of different specifications and types. The cam and the mounting shaft can be fixedly connected by inserting a pin between the first strip pin slot and the second strip pin slot.

[0014] The above-mentioned filter automatic leak tester can be further configured as follows: the flip mechanism includes a base, the base is rotatably connected to an A active flip shaft and a B active flip shaft through bearings, the A active flip shaft and the B active flip shaft are parallel to each other and spaced apart, the A active flip shaft is located on a side away from the B active flip shaft and is provided with an A driven flip shaft, the B driven flip shaft is located on a side away from the A active flip shaft and is provided with a B driven flip shaft, a first transmission gear set is provided between the A active flip shaft and the A driven flip shaft, a second transmission gear set is provided between the B active flip shaft and the B driven flip shaft, the end of the A active flip shaft is linked to a left servo motor, and the end of the B active flip shaft is linked to a right servo motor; A rotating shaft is linked to the lower middle part of the base, and the axial direction of the rotating shaft is perpendicular to the axial direction of the A active flip shaft. A divider is linked to the lower end of the rotating shaft, and the divider drives the base to rotate around the central axis of the rotating shaft through the rotating shaft; position sensors are fixed on both sides of the base, one group of position sensors is distributed between the A active flip shaft and the A driven flip shaft, and the other group of position sensors is distributed between the B active flip shaft and the B driven flip shaft; a left connecting block is fixed on the A driven flip shaft, and a right connecting block is fixed on the B driven flip shaft, and the left connecting block and the right connecting block are respectively connected to the filter linkage plate by screws, and each group of detection clamping tooling is installed on each group of filter linkage plates.

[0015] The divider is controlled by a reduction motor, and the divider drives the base to rotate horizontally through the rotating shaft (such as 180 degrees or the required angle, which changes according to the actual situation). Then the A active flip shaft drives the A driven flip shaft to flip downward through the first transmission gear set, and the filter enters the water for detection; during this period, the B active flip shaft and the B driven flip shaft have followed the base to rotate to the material receiving position to prepare for filter loading, so the detection and loading are carried out simultaneously, which not only improves the detection efficiency, but also the material receiving position and the detection position remain unchanged, simplifying the moving route of the transfer mechanism. Among them, the position sensor is used to detect the position information of the filter linkage plate, that is, to detect the position of the filter. When the flip shaft rotates, the connecting block moves accordingly, thereby driving the filter on the filter linkage plate to flip and detect.

[0016] The above-mentioned automatic filter leak detection machine can be further configured as follows: the detection clamping fixture includes a frame, a plurality of groups of spaced-apart sealing disc assemblies are fixed on the upper end surface of the frame, the sealing disc assembly is linked to a main shaft, the upper end of the main shaft is sealed and connected with a threaded connector, and the main shaft is linked to a main shaft driving mechanism that can drive the main shaft to rotate; a first lifting plate is provided in the frame, the first lifting plate is provided with a linkage hole corresponding to each group of main shafts, the lower part of the main shaft passes through the linkage hole, a buffer spring sleeved on the outer periphery of the main shaft is provided above the first lifting plate, the upper end of the buffer spring is abutted and connected with a third limit block, the third limit block is sleeved on the outer periphery of the main shaft and fixedly connected to the main shaft, a plane bearing is provided between the buffer spring and the first lifting plate, the plane bearing is sleeved on the outer periphery of the main shaft, the lower end surface of the plane bearing is fixed to the first lifting plate, The upper end surface of the plane bearing is in contact with the lower end of the buffer spring; the main shaft is linked with a transmission member distributed below the first lifting plate, the first lifting plate is provided with a countersunk hole below the linkage hole, the transmission member includes a bearing group sleeved on the outer periphery of the main shaft, a fourth limit block fixed to the main shaft is provided below the bearing group, the outer diameter of the bearing group is larger than the inner diameter of the linkage hole and smaller than the inner diameter of the countersunk hole, the first lifting plate is linked with a lifting drive mechanism, the lifting drive mechanism includes several groups of rollers, several groups of mounting grooves are provided on the first lifting plate, each group of rollers is hinged in one group of mounting grooves, a pushing member is provided on one side of the roller, the pushing member is linked with a cylinder, the pushing member is provided with a pushing inclined surface at the end facing the roller, and a reset spring is linked with the lower part of the first lifting plate, the upper end of the reset spring is in contact with the first lifting plate, and the lower end is in contact with the frame.

[0017] The filter is placed on top of the threaded connector by using the filter transfer device, and the filter is slowly pushed downward to be spirally connected with the threaded connector. During this period, the main shaft continues to rotate forward under the drive of the main shaft drive mechanism. Since the spiral entrance position of the threaded hole at the end of each group of filters cannot be kept consistent (caused by factors such as processing errors), the main shaft will be pressed down and move down during the process of moving the filter down and installing the threaded connector, thereby compressing the buffer spring until the main shaft rotates to the threaded connector and the threaded hole at the end of the filter begins to be spirally connected. During this period, the buffer spring will drive the main shaft to reset upward, so a buffer spring must be set here, otherwise the main shaft that is spirally connected later will interfere with the filter and cause damage to the filter. At the same time, the upper end face of the plane bearing can keep rotating with the buffer spring, and its lower end face is fixed on the first lifting plate, so as to avoid the end of the buffer spring from scratching between the first lifting plate and protect the first lifting plate and the buffer spring. After the filter is installed on the threaded connector, the filter transfer device can be withdrawn. At this time, the bearing group is located at the position of the countersunk hole. Then, when the main shaft rotates, the bearing group can prevent scratches between the main shaft and the first lifting plate. Next, the cylinder starts to work, the pusher slides, and the push ramp of the pusher contacts the roller and generates thrust, so that the roller rotates in the installation groove and pushes the first lifting plate down. During the descent of the first lifting plate, the return spring is compressed, providing an upward elastic force for the first lifting plate. When the cylinder stops working, the elastic force of the return spring will push the first lifting plate up and return to its initial position. Among them, the roller and the push ramp are in a rolling push form, which can generate a large thrust and respond quickly, thereby ensuring that the first lifting plate can descend smoothly and quickly.

[0018] The above-mentioned automatic filter leak detector can be further configured as follows: an air inlet passage penetrating along the axial direction is provided in the main shaft, an air outlet passage penetrating along the axial direction and connected to the air inlet passage is provided in the threaded connection part, a group of axial positioning holes is provided on the lower end face of the frame corresponding to each group of main shafts, a lower sealing seat is installed at the axial positioning holes, the lower sealing seat is linked to the main shaft through a bearing, a Y-shaped sealing ring is also provided between the main shaft and the lower sealing seat, an air inlet chamber is provided in the sealing seat, the air inlet chamber is connected to the air inlet passage, and an air inlet nozzle for inflating the air inlet chamber is provided on the side wall of the lower sealing seat.

[0019] During the test, the external air source inflates the air inlet chamber through the air inlet nozzle, and the gas enters the filter through the air inlet and outlet ducts for air tightness testing. By setting the air inlet duct directly inside the main shaft and the air outlet duct in the threaded connector, the gas flow route is greatly simplified, the number of connections is reduced, and the risk of gas leakage is reduced, thereby improving the accuracy and efficiency of the filter air tightness test. The lower sealing seat is linked to the main shaft through the bearing and is equipped with a Y-shaped sealing ring to ensure the sealing of the air inlet chamber.

[0020] The above-mentioned automatic filter leak detection machine can be further configured as follows: the filter transfer device includes a transfer guide rail installed above the frame, a transfer frame that reciprocates along the transfer guide rail, and an openable and closable transfer clamping plate mechanism, and a longitudinal driving component that can drive the transfer clamping plate mechanism to rise and fall vertically is provided between the transfer frame and the transfer clamping plate mechanism; the longitudinal driving component includes a lifting cylinder arranged on both sides of the transfer frame, a second lifting plate linked to the output end of the lifting cylinder, a longitudinal synchronous wheel arranged on the second lifting plate, and a longitudinal synchronous belt sleeved between the longitudinal synchronous wheels, the longitudinal synchronous belt is provided with a connecting block, the connecting block is linked with a third lifting plate, the third lifting plate is equipped with a third slider, and the third slider is slidably connected to a The second lifting plate is provided with a third slide rail, and the second lifting plate is provided with a fourth slider, and the fourth slider is slidably connected to the fourth slide rail fixed on the transfer frame; the transfer clamping plate mechanism includes a main clamp, a sub-clamp, and a clamping drive component for controlling the opening and closing of the main clamp and the sub-clamp, and the main clamp and the sub-clamp are provided with a plurality of first V-shaped clamps corresponding to each other, and the corresponding first V-shaped clamps between the main clamp and the sub-clamp form a quadrilateral clamping position for clamping the filter, and each adjacent two groups of quadrilateral clamping positions are staggered, and the clamping drive component includes an open clamping cylinder arranged on both sides of the main clamp and the sub-clamp, and the output ends of the open clamping cylinder are respectively connected to the main clamp and the sub-clamp, and drive the main clamp and the sub-clamp to move in opposite directions or in opposite directions.

[0021] The lifting cylinder controls the second lifting plate to lift the transfer rack, and the longitudinal synchronous belt controls the second lifting plate to lift relative to the first lifting plate, so two-stage lifting can be achieved, and the lifting range is longer. At the same time, the purpose of "each adjacent set of quadrilateral clamping positions are staggered" is to achieve the clamping of two rows of filters, improve production efficiency, simplify the structure of the equipment as much as possible, and reduce costs.

[0022] The above-mentioned automatic filter leak detection machine can be further configured as follows: the frame is also provided with a feed buffer line distributed on one side of the turntable, the feed buffer line includes a material storage belt and a sprocket linked to the two ends of the material storage belt, the sprocket is linked to a third servo motor, and a material guide guardrail is provided above the material storage belt, the two ends of the material guide guardrail are inclined toward one side of the material storage belt, and the middle part of the material guide guardrail is close to the other side of the material storage belt.

[0023] The storage belt caches multiple sets of filters, and the guide fence guides the filters to the turntable in an orderly manner.

[0024] The above-mentioned automatic filter leak detection machine can be further configured as follows: both ends of the automatic discharging conveyor belt are linked with discharging pulleys, the ends of a group of discharging pulleys are linked with a fourth servo motor, and the ends of the automatic discharging conveyor belt are provided with a discharging transition frame fixed on the frame, and a plurality of groups of third rollers are hinged in the middle of the discharging transition frame.

[0025] The discharge transition rack is used to provide a stable transition platform to ensure that the filter can remain stable when transferring from the automatic discharge conveyor to the next stage (such as another transportation line or subsequent processing equipment), avoiding impact and damage caused by direct drop or sudden change of movement direction. The third roller is installed in the middle of the discharge transition rack. Their main function is to support the filter and reduce the friction resistance of the filter during the transition process by rolling, so that the filter can move more smoothly.

[0028] 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.

[0029] like Figure 1 The filter automatic leak detection machine shown includes a frame, an automatic sorting and unloading device, and an air tightness detection device. An automatic unloading conveyor belt is provided between the automatic sorting and unloading device and the air tightness detection device. A filter transfer device is provided above the automatic unloading conveyor belt. The air tightness detection device includes a water tank h, at least two sets of detection clamping tooling and a flipping mechanism linked to the detection clamping tooling.

[0030] The automatic sorting and unloading device comprises a turntable manipulator module a, an automatic sorting and column separation module b, and a material storage belt c.

[0031] like Figure 2 The two ends of the storage belt c are linked to sprockets, and the sprockets are linked to a third servo motor. A material guide guardrail c1 is provided above the storage belt c. The two ends of the material guide guardrail c1 are inclined toward one side of the storage belt c, and the middle of the material guide guardrail c1 is close to the other side of the storage belt c. The storage belt c caches multiple groups of filters, and the material guide guardrail c1 guides the filters to the turntable in an orderly manner.

[0032] like Figures 4 to 11The turntable manipulator module a shown includes a turntable a1 and a turntable driving mechanism for driving the turntable a1 to rotate. The turntable a1 is provided with a plurality of groups of clamping mechanisms along the circumference. An opening and closing driving mechanism installed on the turntable a1 is provided between the clamping mechanism and the cam a2. The opening and closing driving mechanism can slide radially along the turntable a1. A cam a2 is hinged in the middle of the turntable a1. The turntable driving mechanism can rotate around the cam a2 with the turntable a1. The opening and closing driving mechanism rotates around the cam a2 with the turntable a1 and the end of the opening and closing driving mechanism keeps in contact with the outer peripheral surface of the cam a2, thereby controlling the opening and closing of the clamping mechanism. When the turntable a1 rotates around the cam a2, the end of the opening and closing driving mechanism always keeps in contact with the outer peripheral surface of the cam a2. Due to the shape design of the cam a2 (usually an eccentric or irregular shape), as the turntable a1 rotates, the outer peripheral surface of the cam a2 will periodically change the contact position with the end of the opening and closing driving mechanism, thereby pushing or pulling the opening and closing driving mechanism to slide radially. This sliding motion is then converted into the opening and closing action of the clamping mechanism to achieve the clamping and releasing of the filter. Since the opening and closing drive mechanism is independent and can slide radially along the turntable a1, the opening and closing action of each group of clamping mechanisms can be independently controlled. That is, at a specific workstation, only the clamping mechanism at that workstation can be extended or retracted, while the clamping mechanisms at other workstations remain stationary. The flexibility of the turntable a1 type manipulator is greatly improved, and the working condition requirement that only the clamping jaw a7 of that workstation needs to be extended at a specific workstation is met. Furthermore, the number of driving sources is reduced, and only one turntable drive mechanism is required to drive the movement of the entire turntable a1 and all the clamping mechanisms. At the same time, due to the simple mechanical structure of the cam a2 and the opening and closing drive mechanism, the manufacturing cost and maintenance cost are also reduced. Among them, it should be noted that when the turntable a1 rotates, the cam a2 remains in position.

[0033] The opening and closing driving mechanism includes a pushing block a3, and the turntable a1 is provided with a group of sliding grooves a4 corresponding to each group of pushing blocks a3. A first sliding block a5 adapted to the sliding groove a4 is linked below the pushing block a3. One end of the pushing block a3 keeps in contact with the outer peripheral surface of the cam a2, and the other end extends to the middle of the clamping mechanism. Pushing inclined surfaces a6 are symmetrically provided on both sides of the pushing block a3. The clamping mechanism includes two groups of symmetrically distributed clamping jaws a7. One end of each group of clamping jaws a7 extends to the pushing inclined surface a6, and the middle part is hinged on the turntable a1. Each group of clamping jaws a7 is linked with a group of elastic reset mechanisms. The elastic reset mechanisms push or pull the clamping jaws a7 to rotate around the middle of the clamping jaws a7 so that one end of the clamping jaws a7 keeps in contact with the pushing inclined surface a6.

[0034] When the turntable a1 rotates, one end of the push block a3 contacts the outer peripheral surface of the cam a2 (this is mainly because the elastic reset mechanism always pushes or pulls the clamping claw a7, causing the end of the clamping claw a7 to always contact the push slope a6, exerting a resistance force on the push block a3). As the shape of the cam a2 changes, the push block a3 is pushed or pulled and slides along the slide groove a4. The other end of the push block a3 extends to the middle of the clamping claw mechanism, and push slopes a6 are provided on both sides of it. When the push block a3 slides along the slide groove a4, its push slope a6 will push or pull the clamping claw a7, causing the clamping claw a7 to rotate around its middle to achieve the opening and closing action. Through the cooperation of the cam a2, the opening and closing drive mechanism (the push block a3 and the specific structure of the push block a3), and the elastic reset mechanism, the opening and closing action of the clamping claw mechanism is realized, and the number of driving sources is reduced. The entire turntable a1 type manipulator only needs one turntable drive mechanism to drive the movement of the entire turntable a1 and all the clamping claw mechanisms, which greatly reduces the structural complexity and manufacturing cost. Furthermore, due to the shape of the cam a2, when the turntable a1 rotates, the push block a3 will contact the cam a2 and produce corresponding sliding at the convex or concave points of the cam a2, thereby driving the opening and closing actions of each group of clamping mechanisms in turn. The actions of all clamping mechanisms are carried out simultaneously during the rotation of the turntable a1, without waiting for the previous action to be completed before the next action is carried out, thereby significantly improving work efficiency. Among them, the slide groove a4 and the first slider a5 are set, so that the push block a3 can slide smoothly along the radial direction of the turntable a1 without offset or jamming, thereby ensuring the accuracy and stability of the opening and closing action. The clamping mechanism is designed as a rotatable clamping jaw a7, and the push ramp a6 and the elastic reset mechanism are used to control the opening and closing of the two groups of clamping jaws a7. Compared with the prior art, the clamping jaw cylinder is eliminated, the cost is low, and the corresponding speed is fast.

[0035] The elastic reset mechanism includes a spring seat a8 fixed on the turntable a1. The spring seat a8 is provided with a mounting hole on the side facing the clamping jaw a7. A clamping jaw reset spring a9 is provided in the mounting hole. The end of the clamping jaw reset spring a9 is linked with a push pin a10. A guide strip a11 is provided between one end and the middle part of the clamping jaw a7. The push pin a10 remains in contact with the guide strip a11 under the push of the clamping jaw reset spring a9.

[0036] When the turntable a1 rotates, if the push block a3 passes the high point of the cam a2, the push block a3 moves forward, pushes the inclined surface a6, and squeezes the clamp a7. The guide strip a11 on the clamp a7 squeezes the clamp reset spring a9, generating a pre-tightening force. Once the push block a3 is reset, the clamp reset spring a9 pushes the clamp a7 to reset through the push pin a10, realizing the opening and closing action.

[0037] A first roller a12 is hingedly connected to one end of the pushing block a3, and the first roller a12 is in rolling contact with the outer peripheral surface of the cam a2. The outer peripheral surface of the cam a2 is provided with at least one group of protrusions a13, and the two ends of the protrusions a13 are connected to the cam a2 at curved surfaces. The end of the protrusion a13 is provided with a first limit block a14 fixed on the cam a2, and a second limit block a15 is linked to the upper side of the pushing block a3; a second roller a16 is hingedly connected to one end of the clamping jaw a7, and the second roller a16 is in rolling contact with the pushing inclined surface a6.

[0038] The rolling contact between the first roller a12 and the second roller a16 reduces friction and wear, and improves the flexibility and accuracy of the action of the push block a3 and the clamp a7. Among them, the protrusion a13 is the high point of the cam a2, which realizes the change of the position of the push block a3. The first limit block a14 is designed above a group of protrusions a13, and the second limit block a15 is designed above the push block a3, in order to prevent the clamp a7 from opening too early. Only when the clamp a7 reaches the predetermined position can it be opened, so as to realize rapid discharge and prevent the filter from falling or sliding out.

[0039] A mounting hole is penetrated in the middle of the turntable a1, and a bearing a17 is arranged in the mounting hole. The bearing a17 is linked with a mounting shaft a18, and a conical connecting column a19 is provided at the upper end of the mounting shaft a18. A connecting hole a20 is provided in the middle of the cam a2 and the upper end of the conical connecting column a19. A first strip-shaped latch groove a21 is provided on the outer periphery of the conical connecting column a19, and a conical plug-in hole a22 adapted to the conical connecting column a19 is provided below the cam a2, and a second strip-shaped latch groove a23 is provided on the side wall of the conical plug-in hole a22 corresponding to the first strip-shaped latch groove a21, and the second strip-shaped latch groove a23 runs through the cam a2.

[0040] A bearing a17 is arranged in the mounting hole to realize "the turntable a1 rotates around the cam a2, and the cam a2 is fixed". The mounting shaft a18 is used to mount the cam a2. A conical connecting column a19 and a conical connecting hole a20 are added to adapt to cams a2 of different specifications and types. The cam a2 can be fixedly connected to the mounting shaft a18 by inserting a pin between the first strip pin groove a21 and the second strip pin groove a23.

[0041] A rotating sleeve a24 is linked to the lower middle of the turntable a1, and a clearance hole a25 that is clearance-matched with the installation shaft a18 runs through the middle of the rotating sleeve a24. The turntable driving mechanism includes a reducer a26 linked to the rotating sleeve a24.

[0042] The rotating sleeve a24 is used as a connecting component between the linkage turntable a1 and the reducer a26. The rotating sleeve a24 is clearance-matched with the installation shaft a18 through the giving way hole a25 to achieve smooth rotation of the turntable a1 and avoid wear between the turntable a1 and the installation shaft a18.

[0043] The turntable a1 is provided with a material passing opening slot a27 corresponding to each group of clamping jaw mechanisms, and a feed plate a28 is provided at one group of material passing opening slots a27. A strip detection hole a29 runs through the feed plate a28, and an incoming material sensor a30 is installed at the strip detection hole a29. The incoming material sensor a30 is fixed on a bracket a31, and a second slider a32 is fixedly installed on the bracket a31. The second slider a32 is slidably connected to a second slide rail a33, and the second slide rail a33 is fixed under the feed plate a28. The second slide rail a33 is provided with a plurality of groups of fastening nail holes.

[0044] A material opening slot a27 is provided to facilitate the filter to enter the turntable a1. A feed plate a28 and an incoming material sensor a30 are provided to detect the existence or position of the filter. Once detected, the turntable a1 starts to work. The incoming material sensor a30 is fixed on a bracket a31, and the bracket a31 is slidably connected to the second slide rail a33 through a second slider a32. The second slide rail a33 is fixed below the feed plate a28 and is provided with a plurality of sets of fastening nail holes for adjusting the position of the incoming material sensor a30.

[0045] The specific working principle of the turntable manipulator module a is as follows: when the filter enters the feed plate a28, the incoming material sensor a30 senses the filter, the turntable a1 drives the push block a3 to rotate around the cam a2, the push block a3 is pushed forward by the protrusion a13 on the cam a2, and the clamp a7 holds the filter. The turntable a1 continues to rotate, and when it reaches the other end of the protrusion a13, due to the action of the first limit block a14, the clamp a7 will not open gradually, but when the push block a3 moves to the second limit block a15 and is completely misaligned with the first limit block a14, the clamp a7 will immediately release to achieve material discharge.

[0046] like Figures 12 to 16The automatic sorting and arranging module b shown in the figure comprises a conveyor belt b1, and pulleys b25 are respectively linked at both ends of the conveyor belt b1, and the material transport driving mechanism comprises a second servo motor b26 linked with the pulley b25; it also comprises a left opening and closing plate b2 and a right opening and closing plate b3 relatively distributed on both sides of the conveyor belt b1, and the left opening and closing plate b2 and the right opening and closing plate b3 are linked with an opening and closing driving mechanism that can drive the left opening and closing plate b2 and the right opening and closing plate b3 to be relatively close to or separated, and the left opening and closing plate b2 is located on the side facing the right opening and closing plate b3 and is provided with a plurality of groups of left pushing blocks b4 spaced apart from each other, and the right opening and closing plate b3 is provided with a plurality of groups of left pushing blocks b4 spaced apart from each other. The closing plate b3 is located on the side facing the left opening and closing plate b2, and a group of right material containing grooves b5 are provided corresponding to each group of left pushing material blocks b4, a group of left containing grooves b6 are provided between each two adjacent groups of left pushing material blocks b4, and a group of right pushing material blocks b7 are provided between each two adjacent groups of right material containing grooves b5; when the left opening and closing plate b2 and the right opening and closing plate b3 are close to each other, a group of first column sorting grooves are formed between each group of corresponding left pushing material blocks b4 and the right material containing grooves b5, and a group of second column sorting grooves are formed between each group of right pushing material blocks b7 and the left material containing grooves, and the first column sorting grooves and the second column sorting grooves are staggered with each other.

[0047] The opening and closing driving mechanism includes a mounting frame b11 distributed below the conveyor belt b1, and a plurality of screw rods are hinged on the mounting frame b11. The upper part of the screw rod is provided with a first section of thread b12, and the lower part is provided with a second section of thread b13. The first section of thread b12 and the second section of thread b13 are symmetrical to each other. The screw rod is linked to a left nut sleeve b14 through the first section of thread b12, and is linked to a right nut sleeve b15 through the second section of thread b13. The left nut sleeve b14 is linked to a left slider b16, and the right nut The sleeve b15 is linked to the right slider b17, the left slider b16 is linked to the left opening and closing plate b2, the right slider b17 is linked to the right opening and closing plate b3, a first slide rail b18 is fixed on the mounting frame b11, the left slider b16 and the right slider b17 are respectively slidably matched with the first slide rail b18; the end of the screw rod is linked to a driven pulley b19, the driven pulley b19 is linked to a belt, the belt is linked to a driving pulley b20, and the driving pulley b20 is linked to a first servo motor fixed on the mounting frame b11.

[0048] The first servo motor starts, driving the active pulley b20 to rotate. The active pulley b20 transmits power to the driven pulley b19 through the belt, and the driven pulley b19 is linked with the end of the screw rod to drive the screw rod to rotate. The screw rod is provided with a first section of thread b12 and a second section of thread b13 that are symmetrical to each other. As the screw rod rotates, the left nut sleeve b14 moves upward on the first section of thread b12, and the right nut sleeve b15 moves downward on the second section of thread b13 (or moves in the opposite direction, depending on the rotation direction of the screw rod). This enables the left nut sleeve b14 and the right nut sleeve b15 to move synchronously but in opposite directions. The left nut sleeve b14 is linked with the left slider b16, and the right nut sleeve b15 is linked with the right slider b17. As the nut sleeve moves, the left slider b16 and the right slider b17 slide on the first slide rail b18 respectively, thereby driving the left opening and closing plate b2 and the right opening and closing plate b3 to be relatively close or separated. When the left opening and closing plate b2 and the right opening and closing plate b3 are relatively close, the first row of sorting grooves is gradually formed between the left push block b4 and the right material storage groove b5, and the second row of sorting grooves is gradually formed between the right push block b7 and the left material storage groove. The filters are accurately pushed into these sorting grooves under the conveyor belt b1, realizing automatic sorting and separation of the filters. Among them, the first slide rail b18 and the slider, on the one hand, transmit force, and on the other hand, improve the movement stability of the left opening and closing plate b2 and the right opening and closing plate b3.

[0049] The ends of the left push block b4 and the right push block b7 are both provided with V-shaped guide grooves b8, the opening of the V-shaped guide groove b8 of the left push block b4 faces the right opening and closing plate b3, and the opening of the V-shaped guide groove b8 of the right push block b7 faces the left opening and closing plate b2, the inner ends of the left receiving groove b6 and the inner ends of the right receiving groove are both provided with V-shaped positioning welts b9, and both sides of the outer ends of the left receiving groove b6 and the outer ends of the right receiving groove are both provided with feed guide welts b10 connected to the V-shaped positioning welts b9. When the filter approaches the left push block b4 and the right push block b7, the opening design of the V-shaped guide groove b8 guides the filter to enter the sorting groove smoothly. The V-shaped structure of the V-shaped guide groove b8 can automatically adjust the position of the filter to make it consistent with the direction of the sorting groove, ensuring that the filter can enter the sorting groove accurately and stably. When the filter enters the sorting slot, the feed guide welt b10 is connected to the V-shaped positioning welt b9 to form a continuous guide path, which further guides the filter to enter the sorting slot smoothly and accurately, helping to reduce the friction and collision of the filter during the automatic sorting process, and improve the transmission efficiency and sorting and sorting accuracy of the filter. As the left opening and closing plate b2 and the right opening and closing plate b3 gradually approach, the filter is pushed into the first column sorting slot and the second column sorting slot respectively. The V-shaped positioning welt b9 accurately positions the filter at the inner end of the sorting slot to prevent the filter from shifting during the sorting process.

[0050] The screw rod comprises an upper rod body b21 and a lower rod body b22, a first section of thread b12 is arranged on the outer periphery of the upper rod body b21, a second section of thread b13 is arranged on the outer periphery of the lower rod body b22, a coupling ring b23 is arranged between the upper rod body b21 and the lower rod body b22, one end of the upper rod body b21 is hinged on the mounting frame b11, and the other end is plugged into the coupling ring b23, one end of the lower rod body b22 is hinged on the mounting frame b11, and the other end is plugged into the coupling ring b23, and the side wall of the coupling ring b23 is provided with an open groove b24 that penetrates the side wall, and the two sides of the open groove b24 are detachably connected by screws. By dividing the screw rod into an upper rod body b21 and a lower rod body b22, the entire screw rod structure is more flexible and easy to disassemble and replace. The coupling ring b23 is used to connect the upper rod body b21 and the lower rod body b22 to ensure that they rotate as a whole. At the same time, the detachable connection is achieved through the open groove b24 and the screw.

[0051] A support frame b27 is provided between the two groups of pulleys b25, and the conveyor belt b1 is sleeved on the outer periphery of the support frame b27. A plurality of groups of magnetic parts b28 are provided between the support frame b27 and the conveyor belt b1. The plurality of groups of magnetic parts b28 are fixed to the support frame b27 by screws, and the plurality of groups of magnetic parts b28 are arranged equidistantly in sequence along a direction parallel to the conveyor belt b1. After the filter is transported to the conveyor belt b1, the magnetic part b28 will generate suction on the filter so that the filter will not shake left and right while following the conveyor belt b1, and the position of the filter will not change easily. It should be noted that although the magnetic part b28 will not continue to follow the conveyor belt b1, the way it generates suction on the filter will not affect the advancement of the conveyor belt b1, and the conveyor belt b1 can maintain normal operation; at the same time, the thrust of the left opening and closing plate b2 and the right opening and closing plate b3 is sufficient to overcome the suction of the magnetic part b28 to achieve sorting and sorting of the filters. At the same time, the magnetic part b28 is designed separately from the conveyor belt b1 to facilitate the disassembly and assembly of the magnetic part b28. Furthermore, by controlling the rotation speed of the second servo motor b26, the spacing between each two adjacent groups of filters can be kept consistent, that is, the materials are fed at equal distances, so that the clamping mechanism can more accurately clamp several groups of filters at the same time.

[0052] The specific working principle of the automatic sorting and columnaring module b is as follows: the filter is continuously conveyed from one end to between the left opening and closing plate b2 and the right opening and closing plate b3 by the conveyor belt b1 under the drive of the second servo motor b26. When the filter reaches the predetermined position, the opening and closing driving mechanism (composed of the first servo motor, belt, pulley, screw, nut sleeve, slider and other components) is started to drive the left opening and closing plate b2 and the right opening and closing plate b3 to be relatively close. The left push block b4 on the left opening and closing plate b2 and the right material storage groove b5 on the right opening and closing plate b3 cooperate with each other to form the first column of sorting grooves, while the right push block b7 on the right opening and closing plate b3 cooperates with the left material storage groove on the left opening and closing plate b2 (formed by the left push block b4) to form the second column of sorting grooves. Under the guidance of the V-shaped guide groove b8 and the feed guide edge b10, the filter is accurately pushed into these mutually displaced sorting grooves to realize the automatic sorting and columnaring of the filter. In addition, the magnetic member b28 ensures that the filter remains stable during the conveying process without shaking or shifting, and by controlling the rotation speed of the second servo motor b26, equidistant feeding of the filter can be achieved.

[0053] like Figures 17 to 19 The filter transfer device d shown includes a transfer guide rail d1 installed above the frame, a transfer frame d2 that reciprocates along the transfer guide rail d1, and an openable transfer clamping plate mechanism. A longitudinal driving component that can drive the transfer clamping plate mechanism to rise and fall vertically is provided between the transfer frame d2 and the transfer clamping plate mechanism; the longitudinal driving component includes a lifting cylinder d3 arranged on both sides of the transfer frame d2, a second lifting plate d4 linked to the output end of the lifting cylinder d3, a longitudinal synchronous wheel arranged on the second lifting plate d4, and a longitudinal synchronous belt d5 sleeved between the longitudinal synchronous wheels. A connecting block d6 is provided on the longitudinal synchronous belt d5, and the connecting block d6 is linked to a third lifting plate d7. The third lifting plate d7 is installed with a third slider, and the third slider is slidably connected to a third slide rail fixed to the second lifting plate d4. The plate d4 is installed with a fourth slider, and the fourth slider is slidably connected to a fourth slide rail fixed on the transfer frame d2; the transfer clamp mechanism includes a main clamp d8, an auxiliary clamp d9, and a clamping drive component that controls the opening and closing of the main clamp d8 and the auxiliary clamp d9, and the main clamp d8 and the auxiliary clamp d9 are each provided with a plurality of mutually corresponding first V-shaped clamps, and the corresponding first V-shaped clamps between the main clamp d8 and the auxiliary clamp d9 form a quadrilateral clamping position d10 that can clamp the filter, and each two adjacent groups of quadrilateral clamping positions d10 are staggered. The clamping drive component includes an open clamping cylinder d11 arranged on both sides of the main clamp d8 and the auxiliary clamp d9, and the output ends of the open clamping cylinder d11 are respectively connected to the main clamp d8 and the auxiliary clamp d9, and drive the main clamp d8 and the auxiliary clamp d9 to move in opposite directions or in opposite directions.

[0054] The lifting cylinder d3 controls the second lifting plate d4 to lift and lower the transfer rack d2, and the longitudinal synchronous belt d5 can control the second lifting plate d4 to lift and lower relative to the first lifting plate, so two-stage lifting can be achieved, and the lifting range is longer. At the same time, the purpose of "each adjacent set of quadrilateral clamping positions d10 is staggered" is to achieve clamping of two rows of filters, improve production efficiency, simplify the structure of the equipment as much as possible, and reduce costs.

[0055] Among them, the lifting cylinder d3 can also be replaced by a screw rod, as long as it can control the reciprocating motion of the second lifting plate d4.

[0056] like Figures 20 to 23 The detection clamping tool e shown includes a frame e1, and the upper end surface of the frame e1 is provided with a plurality of groups of product detection positioning holes distributed at intervals, and a group of sealing disk assemblies e2 are fixed at each group of product detection positioning holes, and the sealing disk assembly e2 is linked to a main shaft e4, and the upper end of the main shaft e4 is sealed and connected with a threaded connector e3, and the main shaft e4 is linked to a main shaft driving mechanism that can drive the main shaft e4 to rotate, and a first lifting plate e5 is provided in the frame e1, and the first lifting plate e5 is provided with a linkage hole e6 corresponding to each group of main shafts e4, and the lower part of the main shaft e4 passes through the linkage hole e6, and a buffer spring e7 sleeved on the outer periphery of the main shaft e4 is provided above the first lifting plate e5, and the upper end of the buffer spring e7 is abutted and connected with a third limit block e8, and the third limit block e8 is sleeved on the outer periphery of the main shaft e4 and fixedly connected with the main shaft e4, and the lower end of the buffer spring e7 abuts against the first lifting plate e5, and the main shaft e4 is linked with a transmission member distributed below the first lifting plate e5, and the first lifting plate e5 is linked to the lifting drive mechanism. The first lifting plate e5 is driven to move by the lifting drive mechanism, and the first lifting plate e5 then drives all the main shafts e4 to move downward synchronously through all the transmission parts to achieve the sealing of the lower end surface of the filter, ensuring that all filters are evenly stressed during the test, and improving the accuracy and efficiency of the test. By uniformly controlling the first lifting plate e5, the problem of asynchronous operation of multiple groups of cylinders e12 is avoided. Furthermore, a buffer spring e7 is provided, and when the threaded connector e3 is not installed with the filter, the main shaft e4 can be squeezed and moved downward a small distance. When the threaded connector e3 begins to be spirally connected with the threaded hole at the end of the filter, the buffer spring e7 can help the main shaft e4 to slowly reset, avoiding interference between the threaded connector e3 and the filter.

[0057] The lifting drive mechanism includes several groups of rollers e9, and several groups of mounting grooves are provided on the first lifting plate e5. Each group of rollers e9 is hinged in one group of mounting grooves. A pushing member e10 is provided on one side of the roller e9. The pushing member e10 is linked to a cylinder e12. The pushing member e10 is provided with a pushing inclined surface e11 at the end facing the roller e9. A reset spring e13 is linked to the lower part of the first lifting plate e5. The upper end of the reset spring e13 is in contact with the first lifting plate e5, and the lower end is in contact with the frame e1. A fifth slider e14 is fixed above the pushing member e10. The fifth slider e14 is slidably matched with a fifth slide rail e15, and the fifth slide rail e15 is fixed on the frame e1. When the filter is installed on the threaded connector e3 and the connection is completed, the cylinder e12 starts to work, pushing the pusher e10 to slide along the fifth slide rail e15. The push slope e11 of the pusher e10 contacts the roller e9 and generates thrust, so that the roller e9 rotates in the installation groove and pushes the first lifting plate e5 down. During the descent of the first lifting plate e5, the return spring e13 is compressed, providing an upward elastic force for the first lifting plate e5. When the cylinder e12 stops working, the elastic force of the return spring e13 will push the first lifting plate e5 up and return to its initial position. At the same time, the sliding of the fifth slider e14 on the fifth slide rail e15 ensures the stable movement of the pusher e10 and the roller e9, avoiding shaking and deviation. Among them, the roller e9 and the push slope e11 are in a rolling push form, which can generate a large thrust and respond quickly, thereby ensuring that the first lifting plate e5 can descend smoothly and quickly.

[0058] A guide block e16 is also provided at the installation groove. A rolling clearance hole is provided in the middle of the guide block e16 and is sleeved on the outer periphery of the roller e9. The roller e9 is hinged in the rolling clearance hole and the end of the roller e9 is higher than the end face of the guide block e16. The guide block e16 is provided with a sliding inclined surface e17 on the side facing the pusher e10. When the pusher e10 slides along the fifth slide rail e15 under the push of the cylinder e12 and contacts the roller e9 through the push inclined surface e11 to generate thrust, the roller e9 will roll in the rolling clearance hole of the guide block e16. Since the end of the roller e9 is higher than the end face of the guide block e16, the pusher e10 can smoothly drive the roller e9 to roll without being hindered by the guide block e16. At the same time, a sliding slope e17 is provided on the side of the guide block e16 facing the pushing member e10. When the pushing member e10 contacts the guide block e16, the sliding slope e17 can guide the pushing member e10 to move smoothly, avoiding impact and shaking.

[0059] A plane bearing e18 is provided between the buffer spring e7 and the first lifting plate e5. The plane bearing e18 is sleeved on the outer periphery of the main shaft e4. The lower end surface of the plane bearing e18 is fixed on the first lifting plate e5, and the upper end surface of the plane bearing e18 abuts against the lower end of the buffer spring e7. Since the upper end of the buffer spring e7 maintains an abutting connection with the third limit block e8, when the main shaft e4 rotates, the buffer spring e7 will be driven to rotate. Due to its structural characteristics, the upper end surface of the plane bearing e18 can maintain rotation with the buffer spring e7, and the lower end surface of the plane bearing e18 is fixed on the first lifting plate e5, so that the end of the buffer spring e7 can be prevented from scratching between the first lifting plate e5, thereby protecting the first lifting plate e5 and the spring.

[0060] The first lifting plate e5 is provided with a countersunk hole e19 below the linkage hole e6. The transmission member includes a bearing group e20 sleeved on the outer periphery of the main shaft e4. A fourth limit block e21 fixed on the main shaft e4 is provided below the bearing group e20. The outer diameter of the bearing group e20 is larger than the inner diameter of the linkage hole e6 and smaller than the inner diameter of the countersunk hole e19. If the threaded connector e3 is successfully installed with the filter, the bearing group e20 is located at the position of the countersunk hole e19. Then, when the main shaft e4 rotates, the bearing group e20 can prevent the main shaft e4 from scratching with the first lifting plate e5. When the main shaft e4 moves down slowly, the bearing group e20 will follow and move down until the threaded connector e3 is installed with the filter. The main shaft e4 will slowly rise under the action of the buffer spring e7 until the bearing group e20 also rises to the position of the countersunk hole e19.

[0061] The sealing disc assembly e2 includes a mounting seat e22 fixed at the product detection positioning hole, and an upper sealing seat e23 is linked to the mounting seat e22 through several groups of bearings. The upper sealing seat e23 is sleeved on the outer periphery of the main shaft e4 through several groups of bearings. There are also several groups of Y-shaped sealing rings e24 between the upper sealing seat e23 and the main shaft e4. The upper end of the upper sealing seat e23 is fixed with a sealing disc e25 that can seal the lower end surface of the filter, and the middle of the sealing disc e25 is provided with a through hole that matches the clearance of the main shaft e4. The mounting seat e22 is fixed at the product detection positioning hole as a support for the entire sealing disc assembly e2. The upper sealing seat e23 is sleeved on the outer periphery of the main shaft e4 through several groups of bearings, so that the upper sealing seat e23 can rotate around the main shaft e4 or make a small axial movement. Among them, the Y-shaped sealing ring e24 has good elasticity and sealing performance, and can adapt to the small gap changes between the main shaft e4 and the upper sealing seat e23. The sealing disc e25 is used to fit tightly on the lower end surface of the filter to form an effective seal.

[0062] The spindle e4 is provided with an air inlet e26 that runs through the axis direction, and the threaded connector e3 is provided with an air outlet e27 that runs through the axis direction and communicates with the air inlet e26. The lower end surface of the frame e1 is provided with a group of axial positioning holes corresponding to each group of spindles e4, and a lower sealing seat e28 is installed at the axial positioning holes. The lower sealing seat e28 is linked with the spindle e4 through a bearing, and a Y-shaped sealing ring e24 is also provided between the spindle e4 and the lower sealing seat e28. The lower sealing seat e28 is provided with an air inlet chamber e29, and the air inlet chamber e29 is communicated with the air inlet e26. The side wall of the lower sealing seat e28 is provided with an air inlet nozzle e30 for inflating the air inlet chamber e29. During the detection process, the external air source inflates the air inlet chamber e29 through the air inlet nozzle e30, and the gas enters the filter through the air inlet e26 and the air outlet e27 to perform an air tightness test. By directly setting the air inlet e26 inside the main shaft e4 and setting the air outlet e27 inside the threaded connector e3, the gas flow route is greatly simplified, the number of connections is reduced, thereby reducing the risk of gas leakage and improving the accuracy and efficiency of the filter air tightness detection. The lower sealing seat e28 is linked to the main shaft e4 through the bearing and is provided with a Y-shaped sealing ring e24 to ensure the sealing of the air inlet chamber e29.

[0063] The spindle drive mechanism includes a fifth servo motor e31 installed on one side of the frame e1. The output end of the fifth servo motor e31 is linked with a driving gear e32. The outer periphery of the spindle e4 is relatively fixedly connected with a driven gear e33. A group of transmission gears e34 is provided between each two adjacent groups of spindles e4. Each group of transmission gears e34 is respectively meshed with two adjacent groups of driven gears e33. The transmission gears e34 are rotatably installed on the frame e1. The driven gears e33 on a group of spindles e4 close to the fifth servo motor e31 are meshed with the driving gear e32. The fifth servo motor e31 drives the driving gear e32 to rotate, and the driving gear e32 drives the driven gear e33 to rotate. The transmission gears e34 are used to realize the synchronous rotation of all spindles e4.

[0064] The specific working principle of the inspection clamping tool e is as follows: the filter is placed on the threaded connector e3 by using the filter transfer device, and the filter is slowly pushed downward to be spirally connected with the threaded connector e3. During this period, the main shaft e4 continues to rotate forward under the drive of the main shaft drive mechanism. A part of the threaded connector e3 is successfully installed with the filter, and this part of the main shaft e4 will not move downward. The other part of the threaded connector e3 is spirally connected with the threaded hole at the end of the filter later, which is mainly because the spiral line entrance position of the threaded hole at the end of each group of filters cannot correctly correspond to the spiral line entrance of the threaded connector e3. Therefore, in this case, the main shaft e4 is pressed down and moves downward, and then the buffer spring e7 is compressed, until the main shaft e4 rotates to the threaded hole at the end of the filter and starts to be spirally connected. During this period, the buffer spring e7 will drive the main shaft e4 to reset upward until the filter is installed on the threaded connector e3. After the filter is installed, the fifth servo motor e31 stops working. Next, the cylinder e12 starts to work, pushing the pusher e10 to slide along the fifth slide rail e15. The pusher inclined surface e11 of the pusher e10 contacts the roller e9 and generates thrust, causing the roller e9 to rotate in the mounting groove and push the first lifting plate e5 to descend. During the descent of the first lifting plate e5, the reset spring e13 is compressed, providing an upward elastic force for the first lifting plate e5. The first lifting plate e5 drives the main shaft e4 downward by pushing the bearing assembly e20. During this period, the sealing disc assembly e2 will not reciprocate, so the filter follows the main shaft e4 to move downward until the end face of the filter contacts the upper end face of the sealing disc e25, sealing the end face of the filter to assist in subsequent air tightness testing. When the cylinder e12 stops working, the elastic force of the reset spring e13 will push the first lifting plate e5 up and return to its initial position. Then the fifth servo motor e31 reverses, and the filter transfer device slowly lifts the filter.

[0065] like Figures 24 to 26 The flip mechanism g shown includes a base g1, which is rotatably connected to an active flip shaft A g2 and an active flip shaft B g3 through bearings. The active flip shaft A g2 and the active flip shaft B g3 are parallel to each other and spaced apart. The active flip shaft A g2 is located on a side away from the active flip shaft B g3 and is provided with a driven flip shaft A g4. The driven flip shaft B g5 is located on a side away from the active flip shaft A g2 and is provided with a driven flip shaft B g5. A first transmission gear set is provided between the active flip shaft A g2 and the driven flip shaft A g4, a second transmission gear set is provided between the active flip shaft B g3 and the driven flip shaft B g5, the end of the active flip shaft A g2 is linked to a left servo motor g13, and the end of the active flip shaft B g3 is linked to a right servo motor g14.

[0066] The first transmission gear group includes a first driving gear g6 fixed on the A driving flip shaft g2, and the first driving gear g6 is meshed with a first driven gear g7 fixed on the A driven flip shaft g4; the second transmission gear group includes a second driving gear g8 fixed on the B driving flip shaft g3, and the second driving gear g8 is meshed with a second driven gear g9 fixed on the B driven flip shaft g5.

[0067] A rotating shaft g10 is linked to the lower middle of the base g1. The axis direction of the rotating shaft g10 is perpendicular to the axis direction of the A active flip axis g2. A divider g11 is linked to the lower end of the rotating shaft g10. The divider g11 drives the base g1 to rotate around the central axis of the rotating shaft g10 through the rotating shaft g10. The divider g11 can be controlled by a reduction motor, and the divider g11 drives the base g1 to rotate horizontally (such as 180 degrees or a required angle, which varies according to actual conditions) through the rotating shaft g10.

[0068] Position sensors g12 are fixed on both sides of the base g1. One group of position sensors g12 is distributed between the A active flip shaft g2 and the A driven flip shaft g4, and the other group of position sensors g12 is distributed between the B active flip shaft g3 and the B driven flip shaft g5. The left connecting block d6g16 is fixed on the A driven flip shaft g4, and the right connecting block d6g15 is fixed on the B driven flip shaft g5. The left connecting block d6g16 and the right connecting block d6g15 are respectively connected to the filter linkage plate g17 by screws. The position sensor g12 is used to detect the position information of the filter linkage plate g17, that is, to detect the position of the filter. When the flip shaft rotates, the connecting block d6 moves accordingly, thereby driving the filter on the filter linkage plate g17 to flip and detect. The position sensor g12 can capture the movement information in real time and convert it into electrical signals for transmission and processing. For example, after the air tightness test is completed, it is lifted from the water tank h to the initial position, or the filter is transferred to the filter linkage plate g17 by the filter transfer mechanism. Then, the corresponding signal can be output, and the servo motor and divider g11 can work.

[0069] A plurality of groups of shockproof blocks g18 are provided on the side of the base g1 corresponding to the filter linkage plate g17. When the filter linkage plate g17 is turned over to the original position, the filter linkage plate g17 is prevented from colliding with the base g1.

[0070] A support seat g19 is fixed above the middle of the base g1, and two sets of support holes are arranged above the support seat g19. The middle of the A active flip shaft g2 and the middle of the B active flip shaft g3 are linked to the support holes through bearings, respectively, to improve the structural stability of the A active flip shaft g2 and the B active flip shaft g3, and are not prone to bending.

[0071] The upper end of the support base g19 is detachably connected to a wire collection barrel g20 by screws, a wire collection bin is provided above the wire collection barrel g20, and symmetrically distributed wire outlet bins g21 are provided below the wire collection barrel g20, and two groups of wire outlet bins g21 are respectively placed on both sides of the support base g19. Connecting wires such as wires or cables are first collected in the wire collection barrel g20, and then enter the wire collection bin from the top of the wire collection barrel g20 for storage and arrangement.

[0072] The specific working principle of the flip mechanism g: If the filter linkage plate g17 at the A driven flip shaft g4 is located at the filter loading position, the filter linkage plate g17 at the B driven flip shaft g5 is flipping to the water tank h for air tightness detection. After the filter linkage plate g17 at the A driven flip shaft g4 has installed the filter, and after the filter at the filter linkage plate g17 at the B driven flip shaft g5 has completed the air tightness detection, the filter linkage plate g17 at the B driven flip shaft g5 flips to detach from the water tank h (the position sensor g12 will detect the filter information, and the servo motor will not work until it flips to the correct angle, and the divider g11 will rotate). It can be seen that detection and loading can be carried out simultaneously. The divider g11 is controlled by a reduction motor, and the divider g11 drives the base g1 to rotate horizontally through the rotating shaft g10. The filter linkage plate g17 at the driven flip shaft g4 of A rotates to the position to be tested for air tightness, and then flips into the water tank h for air tightness testing. At the same time, the filter linkage plate g17 at the driven flip shaft g5 of B rotates to the loading position, the filter is taken away, and the next filter to be tested is transported.

[0073] The flip mechanism g realizes simultaneous detection and loading through the cooperation of the left and right flip shafts and the servo motor (for example, when the active flip shaft g2 of A drives a group of filters for detection, the active flip shaft g3 of B can prepare the next group of filters or detect another group of filters), so that the detection and transportation processes of the filters can be carried out in parallel, reducing waiting time and improving overall work efficiency.

[0074] like Figure 3 The two ends of the automatic unloading conveyor belt f shown are linked with unloading pulleys, and the ends of a group of unloading pulleys are linked with a fourth servo motor. The ends of the automatic unloading conveyor belt f are provided with an unloading transition frame f1 fixed on the frame, and the middle part of the unloading transition frame f1 is hinged with several groups of third rollers f2.

[0075] The discharge transition frame f1 is used to provide a stable transition platform to ensure that the filter can remain stable when transferring from the automatic discharge conveyor to the next stage (such as another conveyor line or subsequent processing equipment) to avoid impact and damage caused by direct drop or sudden change of movement direction. The third roller f2 is installed in the middle of the discharge transition frame f1. Their main function is to support the filter and reduce the friction resistance of the filter during the transition process by rolling, so that the filter can move more smoothly.

[0076] Working principle of the whole machine: the stock belt c delivers the filters in order. When the filter enters the feed plate a28, the incoming material sensor a30 senses the filter, the turntable a1 drives the push block a3 to rotate around the cam a2, and the push block a3 is pushed forward by the protrusion a13 on the cam a2, and the clamp a7 holds the filter. The turntable a1 continues to rotate, and when it reaches the other end of the protrusion a13, due to the action of the first limit block a14, the clamp a7 will not open gradually, but when the push block a3 moves to the second limit block a15 and is completely misaligned with the first limit block a14, the clamp a7 will immediately release to realize material discharge. Driven by the second servo motor b26, the conveyor belt b1 continuously transports the filter from one end to between the left opening and closing plate b2 and the right opening and closing plate b3. The opening and closing drive mechanism starts, driving the left opening and closing plate b2 and the right opening and closing plate b3 to be relatively close. The left push block b4 on the left opening and closing plate b2 cooperates with the right material storage groove b5 on the right opening and closing plate b3 to form the first row of sorting grooves, while the right push block b7 on the right opening and closing plate b3 cooperates with the left material storage groove (formed by the left push block b4) on the left opening and closing plate b2 to form the second row of sorting grooves. Guided by the V-shaped guide groove b8 and the feed guide edge b10, the filter is accurately pushed into these mutually offset sorting grooves to achieve automatic sorting and sorting of the filter. The filter transfer device d transfers the filter to a set of inspection clamping fixtures e (this set of inspection clamping fixtures e is detached from the water tank h and facing upwards, and the other set of inspection clamping fixtures e has been flipped over to the water tank h for air tightness testing). When the other set of inspection clamping fixtures e is flipped upward and detached from the water tank h after the inspection is completed, the base g1 rotates and the two sets of positions are swapped. The inspected filter is taken away by the filter transfer device d and transported to the automatic unloading conveyor belt f, and the filter to be inspected is flipped over to the water tank h for air tightness testing.
