[0060] The following describes the details and working principles of the embodiments and examples of the present invention in conjunction with the accompanying drawings. In the drawings, the X-axis is the longitudinal direction, also the front-to-back direction, the Y-axis is the transverse direction, also the left-right direction, and the Z-axis is the vertical direction, also the up-down direction. The orientation or position indicated in the present invention is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description.

[0061] The bridge filter processing equipment includes a conveying mechanism, a feeding mechanism 1, a sealing ring mechanism 2, a filter paper assembly mechanism and a cover plate assembly mechanism 7; the conveying mechanism includes a workpiece seat 32, and the workpiece seat passes through the feeding mechanism 1, the sealing ring mechanism 2, the filter paper assembly mechanism and the cover plate assembly mechanism 7. Figure 1 The sealing ring mechanism 2 is provided with two groups, and the sealing ring is respectively put on the cover plate interface 27 and the upper end cover interface 26. The cover plate interface is covered with a large sealing ring, and the upper end cover interface is covered with a small sealing ring. The workpiece seat 32 passes through the workpiece loading station 11, the feeding station 12, the sealing ring station 13, the first gluing station 14, the turning station 15, the second gluing station 16, the second sealing ring station 17, and the cover plate assembly station 18 in sequence. There are ten stations in the figure, and the required stations can be added or reserved according to the needs.

[0062] The conveying mechanism also includes a transmission chain 33, a sprocket 31 and a positioning component; the sprocket 31 is horizontally rotatably arranged on the frame, and the sprocket 31 rotates intermittently, and a servo motor can be used to drive the sprocket 31 to rotate intermittently. The transmission chain 33 is arranged on the sprocket, and the transmission chain 33 passes through several assembly stations. The engagement section between the transmission chain 33 and the sprocket 31 is a curved surface, and the stability of the curved surface conveying is weak. It is better to use two sprockets, so that the transmission chain has fewer curved surface sections and more straight line sections, which is roughly a runway type. The assembly station is arranged in the straight line section of the transmission chain between the two sprockets. The transmission chain 33 is provided with a workpiece loading station 11 in the curved surface section of one of the sprockets, and the transmission chain 33 is provided with a flipping station 15 in the curved surface section of the other sprocket. The workpiece loading and flipping have lower requirements on the position accuracy, and such an arrangement is more reasonable. The workpiece seat 32 is provided with a plurality of them, and the plurality of workpiece seats 32 are evenly installed on the transmission chain 33. Each station corresponds to a workpiece seat, and each station can operate at the same time, and the workpiece seat cooperates with each station to improve production efficiency. The workpiece seat 32 is locked by a positioning component at the assembly station. The present invention drives the workpiece seat through the workpiece feeding station 11, the feeding station 12, the sleeve sealing ring station 13, the first gluing station 14, the flipping station 15, the second gluing station 16, the sleeve sealing ring second station 17, and the cover plate assembly station 18 in sequence through the sprocket and the transmission chain. When the workpiece seat 32 is assembled at the assembly station, the positioning component locks the workpiece seat 32 at the station, accurately positions the workpiece seat and ensures that the workpiece remains stationary during assembly, so that the assembly operation is carried out stably and the assembly qualification rate is guaranteed; after completing the assembly of the assembly station, the workpiece seat 32 is separated from the positioning component and enters the next station driven by the transmission chain 33, so that the automatic transportation of the workpiece seat 32 is realized, and the transportation is provided for the automatic assembly of the automobile electric bridge filter.

[0063] The periphery of the transmission chain 33 is provided with a guide rail 34, and the guide rail has the same shape as the transmission track of the transmission chain, and the workpiece seat 32 is slidably set on the guide rail 34. The inner side surface 39 and the outer side surface 38 of the guide rail are provided with slide grooves, which are inner slide grooves and outer slide grooves respectively; the bottom of the workpiece seat 32 is provided with two groups of rollers 29 for clamping the guide rail 34, and the two groups of rollers are respectively set to roll with the inner slide groove and the outer slide groove of the guide rail 34. The transmission chain 33 drives the workpiece seat to move along the guide rail, and the transportation is more stable. The guide rail also plays a limiting role. At the assembly station, the left and right positions of the workpiece seat 32 are limited by the transmission guide rail 34, and the front and rear positions of the workpiece seat are locked by the positioning component, so that the workpiece seat remains motionless during assembly.

[0064] The transmission chain 33 includes a chain plate and a chain shaft, the chain plates are connected by the chain shaft, and a workpiece seat 32 is connected to two adjacent chain shafts to achieve installation. Figure 3, the workpiece seat is provided with a positioning groove 30 at the end on the inner side of the transmission; the positioning component includes a positioning wheel 35 and a driving assembly for driving the positioning wheel to enter and exit the positioning groove, the positioning wheel 35 matches the positioning groove 30, and the positioning groove is semicircular, which is more conducive to the positioning wheel entering the positioning groove. In the assembly station, even if there is a slight error in the position of the workpiece seat 32, the positioning wheel 35 can enter the positioning groove 30 and correct the position of the workpiece seat to make the position of the workpiece seat accurate, and lock the workpiece seat in the assembly station; when the positioning wheel is out of the positioning groove, the transmission chain 33 drives the workpiece seat to move. The driving assembly includes a rotating shaft 37 and a swing arm 36, the positioning wheel 35 is installed at one end of the swing arm 36, the other end of the swing arm is connected to the rotating shaft, and the rotating shaft 37 is rotatably set on the frame. In order to reduce costs, two swing arms 36 are installed on a rotating shaft 37, one swing arm corresponds to one assembly station, and the rotation of the rotating shaft 37 can drive the two swing arms 36 to swing, so that the positioning wheel 35 on the swing arm enters the positioning groove 30 or leaves the positioning, the structure is more compact, and the equipment cost is reduced. The rotating shaft 37 can be driven by a cylinder or a motor.

[0065] The workpiece seat 32 is provided with a plurality of independently arranged workpiece slots for placing workpieces, and the plurality of workpiece slots are divided into a cover plate position 19 and an upper end cover position 8, a lower end cover position 10 and a filter paper position 9 arranged side by side. Since the upper end cover and the lower end cover need to be glued later, and the two ends of the filter paper 22 need to be bonded and connected with the upper end cover 21 and the lower end cover 23, the filter paper position 9 is arranged between the upper end cover position 8 and the lower end cover position 10. The upper end cover position and the lower end cover position have through holes 28 penetrating the workpiece seat, which can act on the upper end cover 21 and the lower end cover 23 through the through holes during assembly, so that the upper end cover and the lower end cover cooperate in assembly work.

[0066] The feeding mechanism includes an upper spring device and an upper valve ball device 42. The upper spring device includes a feeding clamp 44, a first material receiving member 45 and a spring conveying component. The spring conveying component includes a first vibrator 47 and a first material blocking member 54. The first vibrator 47 is provided with a first conveying channel 43. The first conveying channel is tilted downward. The discharge port of the first conveying channel 43 is at a low position. The first material blocking member 54 is provided at the discharge end of the first conveying channel, and the first material blocking member 54 enters and exits the first conveying channel 43. The first material receiving member 45 is vertically rotatably provided at the discharge port of the first conveying channel. The first material receiving member 45 includes a main body and a material receiving portion. The discharge port of the first conveying channel 43 is a material receiving station, and the top of the first material receiving member 45 is a transfer station. The feeding clamp 44 moves between the transfer station and the spring feeding station. See attached. Figure 1, the station seat is at the feeding station, the spring feeding station corresponds to the upper end cover position 8 of the station seat, that is, the spring feeding station corresponds to the pressure relief valve housing 50, the spring feeding station and the transfer station are arranged side by side horizontally, and the feeding clamp 44 only needs to be lifted and moved horizontally to deliver the spring of the transfer station to the pressure relief valve housing 50 of the spring feeding station, so that the feeding clamp 44 has a short moving stroke and a fast feeding speed. The feeding clamp 44 can adopt a conventional pneumatic clamp, and the feeding clamp 44 is installed on the first moving seat 48, which moves horizontally and lifts up and down, and the feeding clamp is moved horizontally and lifted up by driving the first moving seat 48 to move horizontally and lift up.

[0067] The receiving part of the first receiving member 45 can be a receiving trough 49 or a receiving column. If it is a receiving column, the spring is sleeved outside the receiving column. The receiving trough 49 is used in the figure, that is, the receiving part is a receiving trough for receiving the spring. The depth of the receiving trough 49 is less than the length of the spring. After the spring enters the receiving trough, part of the spring is outside the receiving trough, and the exposed part is clamped by the feeding clamp 44. The spring conveying component also includes a second stopper 55. The first stopper 54 is close to the discharge port of the first conveying channel 43 relative to the second stopper 55. The spacing between the first stopper and the second stopper is not less than the length of the spring and less than the total length of the two springs. When the spring is discharged, the first stopper 54 exits the first conveying channel 43, and the second stopper 55 enters the first conveying channel. After the spring is discharged, the first stopper 54 enters the first conveying channel 43, and the second stopper 55 exits the first conveying channel. Through the cooperation of the first stopper and the second stopper, it is ensured that one spring is output at a time. At the same time, in order to avoid the problem of empty clamping of the feeding clamp 44, which would lead to the problem of no spring in the pressure relief valve housing 50, the spring conveying component also includes a first sensor 51 for detecting whether there is material between the first material blocking member 54 and the second material blocking member 55. The first material receiving member 45 is provided with a second sensor 52 for detecting whether there is material in the material receiving trough 49. The first sensor 51 and the second sensor 52 are both connected to the controller. The sensor can be a photosensitive sensor. When the first sensor 51 detects that there is material between the first material blocking member 54 and the second material blocking member 55, the second material blocking member enters the first conveying channel 43 to block the spring behind it. When the second sensor 52 detects that there is material in the receiving slot 49 of the first material receiving member 45, the feeding operation proceeds normally. When the first sensor 51 does not detect the spring, it means that there is no material at the discharge port. When the second sensor 52 does not detect the spring, it means that there is no material in the receiving slot 49. The controller sends an instruction to stop the feeding operation. The feeding operation here includes clamping and moving the feeding clamp 44 and rotating the first material receiving member 45, and even includes the operation of the bridge filter processing equipment, so as to ensure that there is a spring every time feeding, thereby reducing the scrap rate.

[0068] The upper valve ball device 42 includes a suction piece 60, a second material receiving piece 58 and a valve ball conveying component; the valve ball conveying component includes a second conveying channel 56, the second conveying channel is tilted downward, the discharge port of the second conveying channel is at a low position, the valve ball is spherical, and can automatically move to the discharge port of the second channel due to gravity. The second conveying channel 56 in the figure is arranged on the second vibrator, and the second vibrator further transports the valve ball in the second conveying channel 56 to the discharge port. The second material receiving piece 58 is arranged at the discharge port of the second conveying channel, and the second material receiving piece 58 is provided with a valve ball accommodating groove 59 for accommodating a valve ball; the suction piece 60 is arranged above the second material receiving piece 58, and moves between the valve ball taking station and the valve ball feeding station. See attached Figure 1 The station seat is at the feeding station 12, and the valve ball feeding station corresponds to the lower end cover position 10 of the station seat, that is, the valve ball feeding station corresponds to the lower end cover 23. The valve ball feeding station and the valve ball taking station are arranged side by side horizontally. The suction member 60 only needs to be lifted and moved horizontally to deliver the valve ball from the valve ball taking station to the cavity of the lower end cover 23 of the valve ball feeding station. In this way, the movement stroke of the suction member 60 is short and the feeding speed is fast. The suction member 60 is installed on the second movable seat 40, and the second movable seat 40 moves horizontally and lifts up and down. The second movable seat 40 lifts up and down and moves horizontally to realize the horizontal movement and lifting of the suction member 60. Figure 1 In the embodiment, the feeding clamp 44 and the suction member 60 are installed on a moving seat, that is, the first moving seat 48 and the second moving seat 40 are integrated into one body, and the feeding clamp 44 and the suction member 60 are synchronously lifted and lowered and moved laterally, thereby reducing power parts and reducing equipment costs. Figure 7-9 In the figure, the feeding clamp 44 and the material suction member 60 are respectively mounted on the first movable seat 48 and the second movable seat 40, and the two are equipped with independent lifting and lateral moving driving members, which are independently controlled and easy to operate.

[0069] The valve ball accommodating groove 59 has a first opening for the valve ball to enter and a second opening for the valve ball to discharge. The first opening faces the second conveying channel 56 and is an inlet, and the second opening faces upward and is an outlet. The valve ball enters and exits the valve ball accommodating groove 59 through the two openings, and the outlet is at the top, which is convenient for the suction piece 60 to take the valve ball. The second material receiving member 58 reciprocates horizontally perpendicularly to the second conveying channel 56 at the material outlet of the second conveying channel 56; when receiving the material, the first opening corresponds to the material outlet of the second conveying channel 56; after receiving the material, the second material receiving member 58 moves horizontally, and the second material receiving member blocks the material outlet of the second conveying channel, and the first opening is blocked by the baffle or block on the side of the material outlet of the second conveying channel 56, and the second opening is at the valve ball taking position, that is, after the valve ball enters the valve ball accommodating groove 59 of the second material receiving member 58, the second material receiving member 58 moves relative to the second conveying channel 56, so that the material outlet of the second conveying channel is misaligned with the valve ball accommodating groove, providing material taking space for the suction member 60 to avoid interference from other valve balls, thereby ensuring that the suction member 60 successfully adsorbs the valve ball. The second material receiving member 58 is provided with a third sensor 53 for detecting whether there is material in the valve ball receiving groove 59. The third sensor is connected to the controller. When the third sensor 53 detects that there is material in the ball valve receiving groove, it operates normally. When the third sensor 53 does not detect the valve ball, the controller sends an instruction to stop the feeding operation. The feeding operation here includes the adsorption and movement of the suction member 60, and even the operation of the bridge filter processing equipment, so as to ensure that there is a valve ball every time the material is added, thereby reducing the scrap rate.

[0070] The sealing ring installation station 13 and the second sealing ring installation station 17 are both provided with a sealing ring installation mechanism 2, and the sealing ring installation mechanism of the sealing ring installation station is described as an example. The sealing ring installation mechanism 2 includes a sealing ring conveying component 62, a sealing ring installation component 63 and a propping component 64. The sealing ring conveying component 62 includes a sealing ring conveying support plate 65 and a material picking clamp 67. The sealing ring conveying support plate 65 is installed on a vibrator 71. The discharge end of the sealing ring conveying support plate 65 is provided with a clearance gap 68 for the material picking clamp 67 to operate. The material picking clamp 67 is lifted up and down and moves between the discharge end of the sealing ring conveying support plate 65 and the propping component 64. In the figure, the propping component 64 is on the left side of the sealing ring conveying component 62, and the material picking clamp 67 only needs to be lifted up and down and moved laterally. The vibrator 71 vibrates to move the sealing ring 61 on the sealing ring conveying support plate 65 toward the discharge end. The sealing ring conveying support plate 65 has a conveying groove 66. The width of the conveying groove 66 matches the outer diameter of the sealing ring, so that the sealing rings can move toward the discharge end one by one and stably; the discharge end of the conveying groove 66 is arc-shaped, and the discharge end of the conveying groove 66 matches the sealing ring, which can better support the sealing ring and prevent the sealing ring at the discharge end from deformation, which is conducive to the material taking clamp 67 to clamp the sealing ring 61.

[0071] The support member 64 includes a support tray 72 and a plurality of support rods 73. The support rods 73 are arranged vertically. The support tray 72 is provided with a plurality of slide grooves 74 corresponding to the support rods 73 and for movement. The support tray 72 is lifted and lowered relative to the support rods 73. The circle formed by the plurality of support rods 73 gathered together is smaller than the inner diameter of the sealing ring. The circle formed by the plurality of support rods 73 dispersedly moved is larger than the inner diameter of the sealing ring and the outer diameter of the sleeve 69. The plurality of support rods 73 are divided into at least three groups. The same group of support rods 73 is mounted on a moving plate 75. The plurality of moving plates are evenly distributed on a circumference, and the moving plate 75 moves radially relative to the support tray 72. The moving plate 75 moves radially, so that the support rods 73 gather or disperse with each other. The more the number of moving plates 75, the more circular the shape formed by the support rods 73. In the figure, there are four movable plates 75, each of which is equipped with three support rods 73, which are distributed on the movable plates 75 in an arc shape, and the 12 support rods 73 roughly form a circle; the movable plates 75 are slidably arranged on the base 78, and the four movable plates 75 are radially gathered, so that the support rods 73 form a small circle, and the four movable plates 75 are radially spread out, and the circle formed by the support rods 73 gradually becomes larger. The material tray 72 is connected to a driving member 79 that drives it to rise and fall, and a vertically arranged guide member 77 is installed on the base 78. The material tray 72 is connected to a sliding member 76 that matches the guide member 77, and the driving member 79 drives the material tray 72 to rise and fall vertically along the guide member 77.

[0072] The sealing ring sleeve component 63 includes a sleeve 69 and a material pushing sleeve 70 sleeved outside the sleeve 69. The sleeve 69 moves between the sealing ring taking station and the sealing ring putting station, and the material pushing sleeve 70 rises and falls relative to the sleeve 69. The sealing ring taking station is set just above the supporting tray 72. When the sleeve 69 is at the sealing ring taking station, it is best that its bottom is flush with the top of the support rod 73 and the sleeve and the supporting tray are on the same center line. After the supporting tray 72 pushes the sealing ring away from the support rod 73, it is directly sleeved on the sleeve 69. See attached Fig.10 The sealing ring installation station and the sealing ring removal station are arranged side by side in a horizontal direction. The sleeve 69 only needs to be lifted and lowered and moved horizontally. The sleeve 69 is installed on a movable seat. The movable seat is lifted and lowered relative to the material support plate 72 and moves horizontally. The material pusher sleeve 70 is lifted and lowered on the movable seat, and the material pusher sleeve and the outer wall of the sleeve are slidably arranged. The sleeve 69 is a hollow tube. When the sealing ring is installed, the hollow tube is installed outside the cover plate interface 27 from top to bottom, so that the end of the hollow tube is aligned with the height of the sealing ring installed on the cover plate interface 27, and the sealing ring is separated from the hollow tube and installed at the required position of the cover plate interface 27.

[0073] The sealing ring mechanism also includes a detection component, which includes a sensor for detecting whether the cover plate interface 27 is covered with a sealing ring, and the sensor is connected to the controller. If the sensor detects that the cover plate interface 27 has a sealing ring, the next process is entered. If no sealing ring is detected, the sealing ring operation is performed. If no sealing ring is detected for a long time, the operation is stopped and an alarm is sounded to remind the staff, who will check the fault, thereby improving the qualified rate of the product.

[0074] The filter paper assembly mechanism includes a gluing device 6, a filter paper primary installation component 3, a flipping component 4 and a filter paper secondary installation component 5. The filter paper 22 passes through the filter paper primary installation component 3, the flipping component 4 and the filter paper secondary installation component 5 in sequence. The gluing device 6 applies glue to the installation grooves of the upper end cover 21 and the lower end cover 23. The filter paper primary installation component 3 installs one end of the filter paper into the installation groove of the upper end cover 21 after gluing, and the end without the lower end cover 23 faces upward. The flipping component 4 flips the filter paper with the upper end cover installed by 180 degrees, so that the end without the lower end cover is facing downward. The filter paper secondary installation component 5 installs the other end of the filter paper into the installation groove of the lower end cover 23 after gluing.

[0075] The filter paper first installation component 3 includes a filter paper clamping assembly, a pushing assembly and a mobile frame 94, and the filter paper clamping assembly and the pushing assembly are arranged on the mobile frame 94. The filter paper clamping assembly includes an upper clamping member 96 and a lower clamping member 97. When the lower clamping member 97 is closed, the minimum inner diameter of the lower clamping opening 88 is smaller than the inner diameter of the upper clamping opening 87 when the upper clamping member 96 is closed, and the upper clamping opening 87 and the lower clamping opening 88 are on the same center line. The lower clamping member 97 includes a first lower clamping head 81 and a second lower clamping head 82. The first lower clamping head and the second lower clamping head include a filter paper clamping portion 86 for clamping the filter paper. The clamping surface 80 of the filter paper clamping portion 86 has an inclined section 85. After the first lower clamping head 81 and the second lower clamping head 82 are closed, the inclined section 85 of the lower clamping opening is an inverted truncated cone, and the lower clamping opening 88 plays a tightening and guiding role. The push assembly includes a push head 95 that rises and falls, and the push head is arranged above the upper clamping member 96 and corresponds to the upper clamping port 87, and is used to push the filter paper 22. When taking the filter paper, the upper clamping member 96 clamps the upper end of the filter paper, and the lower clamping member 97 is not closed; when assembling the filter paper, the lower clamping member 97 is closed and clamps the lower end of the filter paper, and the push head 95 moves downward and pushes the filter paper 22, and the lower end of the filter paper is tightened through the lower clamping port 88 and enters the installation groove. Specifically, the cylindrical filter paper 22 is sleeved from the upper end cover of the pressure relief valve housing 50 downwardly on the outside of the pressure relief valve housing. When taking the filter paper, only the upper clamping member 96 is used to clamp the upper end of the filter paper, so that the filter paper retains a larger inner hole, so that it can be easily sleeved on the outside of the pressure relief valve housing 50. After the upper clamping member 96 clamps the filter paper, the movable frame 94 moves so that the filter paper clamped by the upper clamping member 96 is sleeved outside the pressure relief valve housing 50. At this time, the bottom of the filter paper is close to the mounting groove of the upper end cover 21, and the lower clamping member 97 is closed to tighten the lower end of the loose filter paper. The inverted truncated cone-shaped clamping opening forms a tightening guide opening. The lower end of the filter paper is smaller than the upper end of the filter paper. The pushing head 95 moves downward and pushes the filter paper 22. The filter paper moves downward relative to the upper clamping member 96 and the lower clamping member 97. The lower end of the filter paper is tightened and guided through the lower clamping opening 88 of the lower clamping member 97 to smoothly enter the mounting groove, thereby realizing automatic assembly of the filter paper.

[0076] The inclined section 85 of the filter paper clamping part 86 has a vertical section 84 extending downward from the clamping surface. After the first lower clamping head 81 and the second lower clamping head 82 are closed, the vertical section 84 of the lower clamping opening is cylindrical. After the inclined section 85 at the lower end of the filter paper is gradually tightened, the cylindrical vertical section 84 plays a shaping and stabilizing role, so that the filter paper portion entering the installation groove is in a tightened straight tube shape before entering. In this way, the filter paper portion entering the installation groove has a stable shape and matches the installation groove, and the assembly effect is better.

[0077] The first lower clamping head and the second lower clamping head also include an end cap clamping portion 83 for clamping the end cap, and the end cap clamping portion is arranged below the filter paper clamping portion 86, and the clamping surface of the end cap clamping portion 83 is consistent with the side surface of the end cap. When the lower clamping member 97 is closed, not only the lower end of the filter paper is clamped, but also the upper end cap 21 is clamped together, that is to say, when the mobile frame 94 moves, the filter paper and the upper end cap 21 move together, so that the push head 95 can press the filter paper into the mounting groove of the upper end cap 21 during the movement, thereby improving the efficiency of the filter paper assembly. After the filter paper 22 is assembled with the upper end cap 21, it is moved to the shaping station 20 by the mobile frame 94 for shaping.

[0078] The first lower clamping head 81 and the second lower clamping head 82 move horizontally. When they move toward each other, they are closed, and when they move away from each other, they are opened. The movable frame 94 is provided with a guide member 99 for the horizontal movement of the first lower clamping head and the second lower clamping head. The horizontal movement of the first lower clamping head and the second lower clamping head is stable and the clamping and tightening accuracy is high.

[0079] The mobile frame 94 moves longitudinally and rises and falls; a product taking component 98 is also provided on the mobile frame 94, and the product taking component and the filter paper clamping component are arranged side by side longitudinally, and the product taking component 98 includes a product taking clamp. The movement of the mobile frame 94 drives the filter paper clamping component and the product taking component 98 to move synchronously, and when the filter paper clamping component sends the assembled filter paper to the shaping station 20, the product taking component 98 clamps the shaped filter paper semi-finished product; when the filter paper clamping component takes the upper end cover 21 or assembles the filter paper, the product taking component 98 sends the shaped filter paper semi-finished product to the vacant filter paper station slot, thereby improving the efficiency of filter paper assembly.

[0080] The sample taking clamp includes a plurality of vertically arranged sample taking clamping heads 92, which are evenly arranged on a circumference and move radially; when clamping, the plurality of sample taking clamping heads gather toward the center; when loosening, the sample taking clamping heads spread outwardly. The plurality of sample taking clamps clamp the finalized filter paper semi-finished products by radial movement, shortening the movement stroke of the sample taking clamp and providing more operating space for the filter paper clamping assembly. A counterweight block 25 is sleeved on the top of the filter paper, and the counterweight block is tightly matched with the filter paper 22. The setting of the counterweight block 25 is to keep the filter paper in a cylindrical shape to avoid excessive looseness affecting the clamping operation. The clamping surface of the sample taking clamping head 92 is stepped, and the sample taking clamping head clamps and supports the counterweight block 25, so the clamping effect is better.

[0081] The flipping component includes a clamping member 101, a steering member 102 for driving the clamping member to flip vertically, a shaking member for driving the clamping member to lift and lower reciprocately, and a lifting member for driving the clamping member to move up and down. The clamping member 101 clamps the filter paper semi-finished product assembled at one end and moves it upward to make it separate from the workpiece seat 32, and the steering member 102 makes the filter paper rotate 180 degrees vertically so that the end with the counterweight 25 is facing downward. The shaking member drives the clamping member to move quickly up and down in a short stroke to achieve a shaking effect, so that the counterweight 25 is separated from the filter paper semi-finished product. After the counterweight 25 is removed from the filter paper semi-finished product, the clamping member 101 moves downward to deliver the flipped and counterweighted filter paper semi-finished product to the workpiece seat 32.

[0082] The flipping component also includes a moving component that drives the clamping member to move horizontally, and the moving component drives the clamping member 101 to return to horizontal position after turning. Fig.16 , the horizontal position of the flipped filter paper semi-finished product relative to the workpiece seat 32 changes, and the position of the flipped filter paper semi-finished product does not correspond to the filter paper position on the workpiece seat 32, so the moving component is used to reset it horizontally, so that the lifting component drives the clamping member to move down, and the filter paper semi-finished product returns to the position for taking the filter paper. The lifting component drives the clamping member to rise to the shaking position to provide operating space for the weight removal and shaking.

[0083] The steering component 102 includes a rotating shaft; the shaking component includes a slide plate 103 and a slide seat 104, and the slide plate is vertically reciprocated and lifted on the slide seat; the moving component includes a moving seat 100, and a horizontally arranged first guide rail 106 is arranged on the moving seat 100; the lifting component includes a vertically arranged second guide rail 93; the clamping member 101 is installed on the rotating shaft, the rotating shaft is rotatably arranged on the slide plate 103, the slide seat 104 is slidably arranged on the first guide rail 106, and the moving seat 100 is lifted and lowered on the second guide rail 93. The movement, lifting and rotation of each component can be driven by a cylinder, or a motor combined with a screw mechanism, a synchronous belt, a gear rack and other structures to achieve.

[0084] The filter paper secondary installation component 5 can adopt the same structure as the filter paper primary installation component 3; in addition, since there is no pressure relief valve housing on the lower end cover 23, there is no need to consider whether the filter paper can be sleeved outside the pressure relief valve housing 50. The filter paper secondary installation component 5 can use a clamp to tighten the end of the filter paper and send it into the installation groove of the lower end cover 23.

[0085] The gluing device 6 includes a gluing component, and the gluing component includes a gluing head 89. The glue is extruded through the gluing head 89 and applied to the mounting groove of the upper end cover 21 or the lower end cover 23; it is better that the gluing head can be raised and lowered. When gluing, the gluing head moves down into the mounting groove. Because the filter paper assembly is divided into two times, the gluing component can be provided in two groups, which are used for gluing the upper end cover 21 and the lower end cover 23 respectively. In order to reduce the equipment cost, the gluing component adopts one group. The gluing device 6 also includes a crossbeam 91, and the gluing component moves horizontally on the crossbeam 91 to the first gluing station 14 or the second gluing station 16. The gluing component can be glued to two stations by moving on the crossbeam 91. The two stations share one gluing component for gluing, which can not only realize automatic gluing, but also reduce equipment costs.

[0086] The first gluing station 14 and the second gluing station 16 are arranged symmetrically in the transverse direction, and a turning station 15 is arranged between the first gluing station and the second gluing station. The filter paper first installation component 3 and the filter paper second installation component 5 are arranged in the first gluing station 14 and the second gluing station 16, respectively, and the turning component 4 is arranged in the turning station 15. Figure 1 , the upper end cap position and the lower end cap position are longitudinally arranged side by side in the first gluing station 14 and the second gluing station 16. In the first gluing station, the gluing head 89 corresponds to the upper end cap position 8 and glues the upper end cap 21. In the second gluing station 16, the gluing head 89 corresponds to the lower end cap position 10 and glues the lower end cap 23. The gluing component only needs to move horizontally to correspond to the gluing position on the workpiece seat 32, which not only has a more streamlined structure and lower equipment cost, but also allows the gluing component to be in place more quickly.

[0087] The two ends of the filter paper 22 are bonded to the upper end cover 21 and the lower end cover 23 respectively. It is best if the shape of the glue coating is consistent with the shape of the bonding position, so the shape of the glue coating is circular. The first gluing station and the second gluing station are respectively provided with a first rotating component and a second rotating component, and the first rotating component and the second rotating component are arranged below the workpiece seat 32 and correspond to the through hole 28 of the upper end cover position on the workpiece seat of the first gluing station 14 and the through hole of the lower end cover position 10 on the workpiece seat of the second gluing station 16. When gluing, the gluing head 89 does not move, and the first rotating component or the second rotating component passes through the through hole of the corresponding station to rotate the upper end cover or the lower end cover of the corresponding station, and the upper and lower end covers rotate relative to the gluing head 89, so that the glue extruded by the gluing head is coated in the mounting groove of the end cover and is circular. The first rotating component includes a top plate that rises and falls and a driving member that drives the top plate to rotate, and the outer diameter of the top plate is smaller than the aperture of the through hole. The top plate moves up through the through hole and pushes the upper end cover or the lower end cover of the corresponding station to move up, so that the upper end cover or the lower end cover does not contact the workpiece seat 32, and the driving member drives the top plate to rotate, so that the upper end cover or the lower end cover rotates. The second rotating component can also adopt the same structure.

[0088] The cover assembly mechanism includes a three-axis manipulator 105, which moves horizontally, longitudinally and vertically on the frame to achieve three-axis movement. The three-axis manipulator 105 clamps the filter paper product of the cover assembly station 18 and moves it to the top of the cover position 19, and then moves downward to press the bottom of the filter paper product (i.e., the lower end cover) into the cover 24 to complete the assembly of the bridge filter. The three-axis manipulator 105 can also grab the assembled bridge filter and transfer it to the finished product area 90 to sort the assembled bridge filter.

[0089] The working principle of the preferred embodiment is further described below in conjunction with the accompanying drawings: At the workpiece loading station 11, the cover plate 24, filter paper 22, upper end cover 21, and lower end cover 23 are respectively placed in the workpiece grooves corresponding to the workpiece seat 32, and the motor drives the sprocket 31 to rotate intermittently. Each time it rotates, the transmission chain 33 moves one station, and the workpiece seat 32 of the workpiece loading station 11 moves to the feeding station 12, and the workpiece seat 32 of the feeding station moves to the sealing ring station 13, and so on. After the workpiece seat 32 enters the assembly station, the rotating shaft 37 rotates, causing the swing arm 36 to swing, and the positioning wheel 35 enters the positioning groove 30 of the workpiece seat 32 of the corresponding station.

[0090] At this time, at the feeding station, the first vibrator 47 and the second vibrator vibrate, and the spring and the valve ball move toward the discharge port in the first conveying channel 43 and the second conveying channel 56 respectively, so that there is material at the discharge port. The first material blocking member 54 blocks the discharge port of the first conveying channel 43, the first sensor 51 detects the spring, the second material blocking member 55 enters the first conveying channel, blocks the spring behind, the receiving part of the first material receiving member 45 rotates to the material receiving station, the first material blocking member 54 exits the first conveying channel 43, the spring discharged from the discharge port enters the receiving slot 49, the first sensor 51 does not detect the spring, the second sensor 52 detects the spring, at this time the first material blocking member 54 enters the first conveying channel 43, the second material blocking member 55 exits the first conveying channel 43, the next spring enters between the first material blocking member 54 and the second material blocking member 55, when the first sensor 51 detects the spring, the second material blocking member 55 enters the first conveying channel 43 again. After the first receiving member 45 receives the spring, the transfer station is rotated, and the feeding clamp 44 moves down to clamp the spring of the transfer station, and then moves up and laterally to above the workpiece seat 32 of the feeding station. At this time, the feeding clamp 44 corresponds to the pressure relief valve housing 50 at the upper end cover position, and the feeding clamp 44 moves down to feed the spring into the pressure relief valve housing 50. After the feeding is completed, the feeding clamp 44 moves up and laterally moves to reset. Similarly, the first opening of the second material receiving member 58 corresponds to the discharge port of the second conveying channel 56, and the valve ball enters the valve ball accommodating groove 59. When the third sensor 53 collects information about the valve ball, the second material receiving member 58 moves horizontally to the valve ball taking station, and the discharge port of the second conveying channel 56 is blocked by the second material receiving member 58. The suction member 60 moves downward to absorb the valve ball from the second opening, and then moves upward and laterally to the top of the workpiece seat 32 of the feeding station. At this time, the feeding clamp 44 corresponds to the lower end cover 23, and the suction member 60 moves downward to feed the valve ball into the cavity of the lower end cover 23. After the feeding is completed, the suction member 60 moves upward and moves laterally to reset. In this way, the automatic feeding of the spring and the valve ball is completed.

[0091] In the sealing ring installation station 13 and the second sealing ring installation station 17, the sealing ring installation mechanisms of the two stations install sealing rings on the upper end cover interface 26 and the cover plate interface 27 respectively. The working principles of the two are the same, and the sealing ring installation station 13 is taken as an example for explanation below. The vibrator 71 vibrates to move the sealing ring arranged in the conveying groove 66 toward the discharge end, and the material picking clamp 67 moves down to clamp the sealing ring at the discharge end of the sealing ring conveying support plate 65, and then moves up and moves to the right to the top of the supporting tray 72. At this time, a number of support rods 73 gather together, and the material picking clamp 67 moves down to place the sealing ring 61 on the supporting tray and then sleeve it outside the support rod. After the material picking clamp 67 completes the feeding, it resets, and the movable plate 75 moves radially, and a number of support rods 73 move in the slide groove 74 and stretch the sealing ring so that the inner diameter of the sealing ring is larger than the outer diameter of the sleeve 69. The sleeve 69 moves to the sealing ring taking station, and the driving member 79 drives the supporting tray 72 to move up, pushing the sealing ring that is sleeved outside the support rod 73 and stretched up, and the supporting tray 72 fits with the bottom of the sleeve 69, and the sealing ring is separated from the support rod 73 and sleeved outside the sleeve. The cover plate interface is at the sealing ring installation position, and the sleeve 69 with the sealing ring is moved to the top of the cover plate interface, and then moved down to the sealing ring installation position. At this time, the bottom of the sleeve 69 is at the position of the sealing ring on the cover plate interface, and the pushing sleeve 70 moves down relative to the sleeve 69 and pushes the sealing ring, so that the sealing ring is separated from the sleeve 69 and is installed on the cover plate interface 27. After the sealing ring is installed, the sleeve 69 moves up and moves horizontally to reset, and the pushing sleeve 70 also moves up and resets.

[0092] At the first gluing station 14, the gluing head 89 moves down, and the top plate of the first rotating component moves up, pushing the upper end cover 21 of the first gluing station to move up, so that the gluing head 89 enters the installation groove of the upper end cover 21 or approaches the installation groove, and the gluing head squeezes out the glue, and the top plate drives the upper end cover to rotate one circle. After the upper end cover 21 is glued, the top plate moves down and resets, and the upper end cover is placed in the upper end cover position 8. The gluing head 89 moves up and moves along the crossbeam 91 to the second gluing station 16 to glue the lower end cover 23 of the second gluing station. When the upper end cover 21 is being glued, the movable frame 94 of the filter paper first mounting component 3 moves to the position where the filter paper is located. At this time, the product taking clamp has clamped the shaped filter paper semi-finished product (one end of the filter paper is bonded to the upper end cover 21) from the shaping station 20, and the upper clamping member 96 clamps the upper end of the filter paper so that the filter paper retains a larger inner hole, and then the movable frame 94 moves up and then moves to the left to just above the upper end cover 21, and then the movable frame 94 moves down to cover the filter paper 22 on the outside of the pressure relief valve housing 50 connected to the upper end cover, and the lower end of the filter paper is close to the mounting groove of the upper end cover 21, and the lower clamping member 97 is closed, the filter paper clamping part 86 clamps the lower end of the filter paper, and the end cover clamping part 83 clamps the upper end cover 21, the lower end of the filter paper is tightened, and the outer diameter becomes smaller; at the same time, the product taking clamp delivers the clamped shaped filter paper semi-finished product to the filter paper position 9, and releases the filter paper semi-finished product. After the filter paper clamping part 86 clamps the upper end cover 21, the movable frame 94 moves up and moves to the right to the shaping station 20. During this process, the pushing head 95 moves down to push the filter paper 22 downward relative to the upper clamping member 96 and the lower clamping member 97. The lower end of the filter paper passes through the inclined section 85 and the vertical section 84 of the filter paper clamping part 86. The inclined section 85 gradually tightens the filter paper and the vertical section 84 keeps the filter paper tightened. In this way, the lower end of the filter paper is smoothly tightened and introduced into the installation groove, and the lower end of the filter paper is bonded to the upper end cover 21. The bonded filter paper and the upper end cover 21 are sent to the shaping station 20, and the sample clamp clamps the semi-finished filter paper that has been shaped.

[0093] At the flipping station 15, the clamping member 101 clamps the semi-finished filter paper, and then the lifting member drives the clamping member to move upward, the semi-finished filter paper leaves the workpiece seat 32, and the steering member 102 drives the clamping member to rotate 180 degrees clockwise, so that the counterweight block 25 of the semi-finished filter paper faces downward and the upper end cover 21 faces upward, and the moving member drives the clamping member to move horizontally to above the filter paper position 9, and the shaking member drives the clamping member 101 to move back and forth rapidly up and down, and the short-stroke rapid movement causes the counterweight block 25 to separate from the filter paper, and then, the lifting member drives the clamping member to move downward, and the semi-finished filter paper without the counterweight block is delivered to the filter paper position 9.

[0094] At the second gluing station 16, the gluing head 89 glues the lower end cover 23 of the second gluing station 16, the filter paper clamping assembly of the filter paper secondary installation component 5 clamps the semi-finished filter paper, and the product taking assembly of the filter paper secondary installation component 5 has clamped the finalized filter paper finished product from the shaping station 20 (the other end of the filter paper is bonded to the lower end cover 23). After the lower end cover is glued, the filter paper secondary installation component 5 bonds the other end of the filter paper to the lower end cover, and the product taking assembly delivers the finalized filter paper finished product to the filter paper position 9; finally, the filter paper clamping assembly delivers the bonded finished product to the shaping station 20 for shaping, and the product taking assembly clamps the finalized finished product at the shaping station.
