Description

Technical Field

[0001] This utility model relates to an invention of a bridge filter processing equipment. Background Technology

[0002] Automotive power bridge filters are used to filter transmission oil. They mainly consist of a cover plate, filter paper, an upper cover, a lower cover, and a pressure relief valve. The pressure relief valve includes a spring and a valve ball. The upper cover is coaxial with the pressure relief valve housing and is designed as a single unit, with the spring installed inside the hollow housing. The lower cover has a cantilever that engages with the other end of the housing, forming a cavity in which the valve ball is placed. The filter paper is formed into a cylindrical shape and fitted over the housing; one end of the filter paper is bonded to the upper cover, and the other end is bonded to the lower cover.

[0003] Existing automotive electric bridge filters are assembled manually, especially the filter paper. The filter paper has a steel wire layer, which has a certain rigidity but also has the problem of unstable shape, making assembly difficult, resulting in low assembly efficiency and high labor costs. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the technical problem to be solved by this utility model is to provide an electric bridge filter processing equipment to realize the automatic assembly of electric bridge filters.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the processing equipment for the electric bridge filter is characterized in that it includes a conveying mechanism, a sealing ring mechanism, a filter paper assembly mechanism, and a cover plate assembly mechanism; the conveying mechanism includes a workpiece seat, and the workpiece seat passes through the sealing ring mechanism, the filter paper assembly mechanism, and the cover plate assembly mechanism.

[0006] The cover plate, filter paper, upper end cover, and lower end cover of the electric bridge filter are placed on the workpiece seat. The workpiece seat delivers each workpiece to the assembly station, where they are assembled by various mechanisms. The sealing ring fitting mechanism fits a sealing ring onto the upper end cover and / or the end cover on the workpiece seat. The filter paper assembly mechanism assembles the filter paper on the workpiece seat with the upper and lower end covers. The cover plate assembly mechanism assembles the lower end cover on the workpiece seat with the cover plate, thus realizing the automatic assembly of the electric bridge filter.

[0007] Preferably, the conveying mechanism further includes a drive chain and sprockets.

[0008] The sprocket is horizontally rotatable on the frame, and rotates intermittently. The drive chain is mounted on the sprocket.

[0009] The transmission chain passes through several assembly stations.

[0010] The workpiece holder is provided in several units, and the several workpiece holders are evenly installed on the transmission chain.

[0011] The workpiece holder is provided with several independently set workpiece slots for placing workpieces. The workpiece slots are divided into covered positions and upper cover positions, lower cover positions and filter paper positions arranged side by side. The upper cover positions and lower cover positions have through holes that penetrate the workpiece holder.

[0012] The cover plate, upper cover, lower cover and filter paper are placed into the workpiece slot of the workpiece holder according to the set position, and the workpiece holder is driven by the sprocket and transmission chain to pass through each assembly station for assembly.

[0013] Preferably, there are two sprockets, and the transmission chain has a workpiece loading station on the curved section of one of the sprockets, and an assembly station on the straight section between the two sprockets.

[0014] The transmission chain has a turning station on the curved section of another sprocket;

[0015] The conveying mechanism also includes a positioning component, and the workpiece seat is locked by the positioning component at the assembly station.

[0016] The workpiece seat has a positioning groove at the inner end of the transmission side;

[0017] The positioning component includes a positioning wheel and a drive assembly that drives the positioning wheel to move in and out of the positioning groove, wherein the positioning wheel is matched with the positioning groove;

[0018] The transmission chain is surrounded by a guide rail, which has the same shape as the transmission trajectory of the transmission chain, and the workpiece seat is slidably mounted on the guide rail.

[0019] When the workpiece holder is assembled at the assembly station, the positioning component locks it in place, precisely positioning it and ensuring it remains stationary during assembly. This guarantees stable assembly operations and a high assembly pass rate. Stable positioning along the straight section leads to a higher success rate in workpiece assembly. After completing assembly at this station, the workpiece holder detaches from the positioning component and moves to the next station via the drive chain.

[0020] Preferably, the bridge filter processing equipment further includes a feeding mechanism, which includes an upper spring device, comprising a feeding clamp, a first receiving component, and a spring conveying component.

[0021] A spring conveying component includes a first vibrator and a first baffle. The first vibrator is provided with a first conveying channel, which is inclined downwards. The outlet of the first conveying channel is at a low position. The first baffle is provided at the outlet end of the first conveying channel and enters and exits the first conveying channel.

[0022] The first receiving component is vertically rotatably disposed at the outlet of the first conveying channel. The first receiving component includes a body and a receiving part. The outlet of the first conveying channel is the receiving station, and the area above the first receiving component is the transfer station.

[0023] The feeding clamp moves between two stations: the transfer station and the spring feeding station.

[0024] The receiving part is a receiving groove for receiving the spring, and the depth of the receiving groove is less than the length of the spring;

[0025] The first receiving component is equipped with a second sensor to detect whether there is material in the receiving trough, and the second sensor is connected to the controller.

[0026] The first vibrator vibrates and conveys the springs in the first conveying channel to the discharge port. The first stopper blocks the discharge port of the first conveying channel. When the receiving part rotates to the receiving position, the first stopper exits the first conveying channel and receives the springs discharged from the discharge port. When the first stopper re-enters the first conveying channel, it blocks the springs behind it. The first receiving part rotates and the receiving part rotates to the transfer position. The feeding clamp clamps the springs transferred by the receiving part and sends the springs to the spring feeding position for feeding. After the springs in the receiving part are removed, the first receiving part rotates and rotates the receiving part to the receiving position, thus realizing the transfer and feeding of springs.

[0027] Preferably, the feeding mechanism further includes an upper valve ball device, which includes a suction component, a second receiving component, and a valve ball conveying component;

[0028] A valve ball conveying component includes a second conveying channel, which is inclined downwards and has a discharge port at a low position.

[0029] The second receiving component is provided at the outlet of the second conveying channel, and the second receiving component is provided with a valve ball receiving groove for accommodating a valve ball.

[0030] The suction component is positioned above the second receiving component and moves between the valve ball picking station and the valve ball feeding station.

[0031] The valve ball in the second conveying channel moves automatically towards the discharge port due to gravity and enters the valve ball receiving groove of the second receiving component. The suction component picks up the valve ball in the valve ball receiving groove and sends it to the valve ball feeding station to realize the automatic feeding of the valve ball.

[0032] Preferably, the sealing ring mechanism includes a sealing ring component and a spreading component;

[0033] A sealing ring assembly includes a sleeve and a pusher sleeve fitted outside the sleeve. The sleeve moves between a sealing ring taking position and a sealing ring fitting position, and the pusher sleeve moves up and down relative to the sleeve.

[0034] The support component includes a material support plate and several support rods. The sealing ring taking position is set directly above the material support plate. The support rods are set vertically. The material support plate has several sliding grooves corresponding to the support rods and for movement. The material support plate rises and falls relative to the support rods. The circle formed by the several support rods when they are gathered together is smaller than the inner diameter of the sealing ring. The circle formed by the several support rods when they are dispersed and moved is larger than the inner diameter of the sealing ring and the outer diameter of the sleeve.

[0035] The sealing ring assembly also includes a sealing ring conveying component, which comprises a sealing ring conveying tray and a material handling clamp.

[0036] A sealing ring conveying tray is mounted on a vibrator, and the discharge end of the sealing ring conveying tray has a clearance notch for the material pick-up clamp to operate.

[0037] The material clamp moves up and down and between the discharge end of the sealing ring conveyor plate and the supporting component.

[0038] The sealing ring is placed on the material support tray and fitted over the gathered support rod. The support rod moves apart and expands the sealing ring, increasing its inner diameter. The sleeve moves to the sealing ring picking position, and the material support tray rises relative to the support rod, pushing the sealing ring off the support rod and onto the sleeve at the sealing ring picking position. After receiving the sealing ring, the sleeve moves to the sealing ring fitting position. The pusher sleeve pushes the sealing ring fitted on the sleeve, causing the sealing ring to detach from the sleeve and fit over the bridge filter interface. This achieves automatic sealing of the bridge filter interface.

[0039] Preferably, the filter paper assembly mechanism includes a filter paper initial installation component, which comprises a filter paper clamping assembly, a pushing assembly, and a moving frame. The filter paper clamping assembly and the pushing assembly are disposed on the moving frame.

[0040] A filter paper clamping assembly includes an upper clamping member and a lower clamping member. When the lower clamping member is closed, the minimum inner diameter of its lower clamping opening is smaller than the inner diameter of the upper clamping opening when the upper clamping member is closed, and the upper and lower clamping openings are on the same center line.

[0041] The lower clamping member includes a first lower clamping head and a second lower clamping head. The first lower clamping head and the second lower clamping head include a filter paper clamping part for clamping filter paper. The clamping surface of the filter paper clamping part has an inclined section. After the first lower clamping head and the second lower clamping head are closed, the inclined section of the lower clamping opening is an inverted frustum shape.

[0042] The pushing component includes a vertically movable pushing head, which is positioned above the upper clamping member and corresponds to the upper clamping opening.

[0043] When taking the filter paper, the upper clamping member clamps the upper end of the filter paper, and the lower clamping member is not closed; when assembling the filter paper, the lower clamping member closes and clamps the lower end of the filter paper, the pushing head moves down and pushes the filter paper, and the lower end of the filter paper passes through the lower clamping port and is tightened into the mounting groove.

[0044] When the filter paper is first installed, the upper clamping member holds the upper end of the filter paper, while the lower clamping member is not closed. At this time, the inner diameter of the filter paper is relatively large, allowing it to be easily fitted onto the pressure relief valve housing. As the moving frame moves, the upper clamping member holding the filter paper moves to directly above the end cover, with the bottom of the filter paper corresponding to the mounting groove on the end cover. At this time, the lower clamping member closes, and the inverted frustum-shaped clamping opening forms a tightening guide opening, gradually tightening the loose filter paper so that the bottom of the filter paper can smoothly enter the mounting groove. At this time, the lower end of the filter paper is smaller than the upper end. The pushing head moves down and pushes the filter paper, causing the filter paper to move down relative to the upper and lower clamping members. The lower end of the filter paper is tightened and guided into the mounting groove through the lower clamping opening of the lower clamping member, thus realizing the automatic assembly of the filter paper.

[0045] Preferably, the inclined clamping surface of the filter paper clamping part extends downward into a vertical section, and after the first lower clamping head and the second lower clamping head are closed, the vertical section of the lower clamping opening is cylindrical.

[0046] The first lower clamping head and the second lower clamping head also include an end cap clamping part for clamping the end cap. The end cap clamping part is disposed below the filter paper clamping part, and the clamping surface of the end cap clamping part matches the side of the end cap.

[0047] The mobile frame moves longitudinally and rises and falls vertically.

[0048] The mobile frame is also equipped with a product retrieval component, and the product retrieval component and the filter paper clamping component are arranged side by side in a longitudinal direction. The product retrieval component includes a product retrieval clamp.

[0049] The product retrieval clamp includes a plurality of vertically arranged product retrieval clamping heads, which are evenly arranged on a circumference and move radially; when clamping, the plurality of product retrieval clamping heads converge toward the center.

[0050] A counterweight is fitted on the top of the filter paper, and the counterweight fits tightly with the filter paper. The clamping surface of the sample-taking clamping head is stepped, and the sample-taking clamping head clamps and supports the counterweight.

[0051] The cylindrical clamping opening serves to shape and stabilize the filter paper, ensuring it is cylindrical before entering the mounting slot. This guarantees a stable shape and proper fit within the slot, resulting in better assembly. The moving frame synchronizes the movement of the filter paper clamping assembly and the product retrieval assembly. When the filter paper clamping assembly delivers the assembled filter paper to the shaping station, the product retrieval assembly picks up the shaped filter paper. Conversely, when the filter paper clamping assembly retrieves the top cover or assembles the filter paper, the product retrieval assembly places the shaped filter paper into the empty space, thereby improving the efficiency of filter paper assembly.

[0052] Preferably, the filter paper assembly mechanism also includes a filter paper secondary installation component and a flipping component, with the filter paper passing through the filter paper primary installation component, the flipping component, and the filter paper secondary installation component in sequence.

[0053] A counterweight is fitted on top of the filter paper, and the counterweight is tightly fitted to the filter paper.

[0054] The flipping component includes a clamping component, a steering component that drives the clamping component to flip vertically, a shaking component that drives the clamping component to move up and down reciprocally, and a lifting component that drives the clamping component to move up and down.

[0055] The flipping component also includes a moving component that drives the clamping member to move horizontally, and the clamping member is horizontally reset after the moving component drives the turning direction;

[0056] The lifting component drives the clamping component to rise to the shaking station;

[0057] The filter paper assembly mechanism also includes an adhesive applicator, which includes an adhesive applicator component and an adhesive applicator head.

[0058] The gluing device also includes a crossbeam, and the gluing component moves laterally on the crossbeam to a first gluing station or a second gluing station. At the first gluing station, the gluing head corresponds to the upper end cap position, and at the second gluing station, the gluing head corresponds to the lower end cap position.

[0059] The first gluing station and the second gluing station are arranged symmetrically in the horizontal direction, and the flipping station is located between the first gluing station and the second gluing station;

[0060] The filter paper initial installation component and the filter paper secondary installation component are respectively set at the first gluing station or the second gluing station, and the flipping component is set at the flipping station;

[0061] The first gluing station and the second gluing station are respectively provided with a first rotating component and a second rotating component. The first rotating component and the second rotating component are located below the workpiece seat and correspond to the through hole of the upper end cap on the workpiece seat of the first gluing station and the through hole of the lower end cap on the workpiece seat of the second gluing station, respectively.

[0062] At the first gluing station, the filter paper is bonded to the upper end cap to form a semi-finished filter paper. At the flipping station, the flipping component flips the semi-finished filter paper and removes the counterweight. Then it enters the second gluing station, where the other end of the semi-finished filter paper is bonded to the lower end cap to form the finished filter paper.

[0063] Preferably, the workpiece seat passes through the workpiece loading station, feeding station, sealing ring installation station, first gluing station, flipping station, second gluing station, second sealing ring installation station, and cover plate assembly station in sequence.

[0064] The cover plate assembly mechanism includes a three-axis robot. The three-axis robot grips the finished filter paper and moves it directly above the cover plate position, and then presses the finished filter paper into the end cap. Attached Figure Description

[0067] The following description, in conjunction with the accompanying drawings, details the embodiments and working principles of this utility model. In the figures, the X-axis represents the longitudinal direction (also the front-to-back direction), the Y-axis represents the transverse direction (also the left-to-right direction), and the Z-axis represents the vertical direction (also the up-down direction). The orientations or positions indicated by this utility model are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description.

[0068] This type of bridge filter processing equipment includes a conveying mechanism, a sealing ring assembly mechanism 2, a filter paper assembly mechanism, and a cover plate assembly mechanism 7; the conveying mechanism includes a workpiece seat 32, which passes through the sealing ring assembly mechanism 2, the filter paper assembly mechanism, and the cover plate assembly mechanism 7. (See attached document) Figure 1 The electric bridge filter processing equipment also includes a feeding mechanism 1 and a sealing ring fitting mechanism 2, which has two sets, respectively fitting the sealing rings onto the cover plate interface 27 and the upper end cover interface 26. The cover plate interface fits the large sealing ring, and the upper end cover interface fits the small sealing ring. The workpiece seat 32 sequentially passes through the workpiece loading station 11, the feeding station 12, the sealing ring fitting station 13, the first gluing station 14, the flipping station 15, the second gluing station 16, the second sealing ring fitting station 17, and the cover plate assembly station 18. There are ten stations shown in the figure. Additional stations can be added or reserved as needed.

[0069] The conveying mechanism also includes a transmission chain 33, a sprocket 31, and positioning components. The sprocket 31 is horizontally rotatable on the frame and rotates intermittently, which can be driven by a servo motor. The transmission chain 33 is mounted on the sprocket and passes through several assembly stations. The meshing section between the transmission chain 33 and the sprocket 31 is curved. Curved surface conveying has weaker stability, so it is better to use two sprockets. This reduces the number of curved sections and increases the number of straight sections in the transmission chain, roughly resembling a racetrack. The assembly stations are located on the straight sections of the transmission chain between the two sprockets. The transmission chain 33 has a workpiece loading station 11 on the curved section of one sprocket and a flipping station 15 on the curved section of the other sprocket. The workpiece loading and flipping have lower requirements for positional accuracy, making this arrangement more reasonable. Several workpiece seats 32 are provided, and these workpiece seats 32 are evenly installed on the transmission chain 33. Each station corresponds to one workpiece seat, and each station can operate simultaneously. The workpiece seats cooperate in operation at each station, thus improving production efficiency. The workpiece seat 32 is locked by a positioning component at the assembly station. This utility model drives the workpiece seat through a sprocket and transmission chain to pass through the workpiece loading station 11, feeding station 12, sealing ring installation station 13, first gluing station 14, flipping station 15, second gluing station 16, second sealing ring installation station 17, and cover plate assembly station 18 in sequence. When the workpiece seat 32 is assembled at the assembly station, the positioning component locks the workpiece seat 32 at that station, accurately positioning the workpiece seat and ensuring that the workpiece remains stationary during assembly, so that the assembly operation can proceed stably and the assembly qualification rate can be guaranteed. After the assembly at the assembly station is completed, the workpiece seat 32 is released from the positioning component and enters the next station under the drive of the transmission chain 33, thus realizing the automatic conveying of the workpiece seat 32 and providing conveying for the automatic assembly of automotive electric bridge filters.

[0070] The transmission chain 33 is surrounded by a guide rail 34, the guide rail having the same transmission trajectory shape as the transmission chain. The workpiece seat 32 is slidably mounted on the guide rail 34. The guide rail has inner and outer grooves, namely an inner groove and an outer groove, respectively. The bottom of the workpiece seat 32 has two sets of rollers 29 that clamp the guide rail 34, and these rollers roll along the inner and outer grooves of the guide rail 34, respectively. The transmission chain 33 drives the workpiece seat to move along the guide rail, making the transport more stable. The guide rail also acts as a limiter; 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 positioning components, keeping the workpiece seat stationary during assembly.

[0071] The transmission chain 33 includes chain plates and chain shafts. The chain plates are connected by the chain shafts. A workpiece seat 32 is connected to two adjacent chain shafts for installation. (See attached document) Figure 3The workpiece seat has a positioning groove 30 on the inner side of the transmission. The positioning component includes a positioning wheel 35 and a drive assembly for driving the positioning wheel in and out of the positioning groove. The positioning wheel 35 matches the positioning groove 30, which is semi-circular, making it easier for the positioning wheel to enter. At the assembly station, even if there is a slight error in the position of the workpiece seat 32, the positioning wheel 35 can still enter the positioning groove 30 and correct the position of the workpiece seat, making the position of the workpiece seat accurate and locking the workpiece seat at the assembly station. When the positioning wheel disengages from the positioning groove, the transmission chain 33 drives the workpiece seat to move. The drive assembly includes a rotating shaft 37 and a swing arm 36. The positioning wheel 35 is mounted on one end of the swing arm 36, and the other end of the swing arm is connected to the rotating shaft. The rotating shaft 37 is rotatably mounted on the frame. To reduce costs, two swing arms 36 are mounted on a rotating shaft 37, with one swing arm corresponding to one assembly station. Rotation of the rotating shaft 37 drives the two swing arms 36 to swing, causing the positioning wheels 35 on the swing arms to enter or disengage from the positioning slots 30. This results in a more compact structure and reduces equipment costs. The rotating shaft 37 can be driven by a cylinder or a motor.

[0072] The workpiece holder 32 has several independently arranged workpiece slots for placing workpieces. These slots are divided into a cover plate position 19 and an upper cover position 8, a lower cover position 10, and a filter paper position 9 arranged side-by-side. Because the upper and lower covers need to be glued later, and the two ends of the filter paper 22 need to be bonded to the upper cover 21 and the lower cover 23, the filter paper position 9 is located between the upper cover position 8 and the lower cover position 10. The upper and lower cover positions have through holes 28 penetrating the workpiece holder, allowing the upper cover 21 and the lower cover 23 to cooperate during assembly.

[0073] 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 receiving member 45, and a spring conveying component. The spring conveying component includes a first vibrator 47 and a first stop member 54. The first vibrator 47 is provided with a first conveying channel 43, which is inclined downwards. The outlet of the first conveying channel 43 is at the lower end. The first stop member 54 is located at the outlet end of the first conveying channel and enters and exits the first conveying channel 43. The first receiving member 45 is vertically rotatably located at the outlet of the first conveying channel. The first receiving member 45 includes a body and a receiving part. The outlet of the first conveying channel 43 is the receiving station, and the area above the first receiving member 45 is the transfer station. The feeding clamp 44 moves between the transfer station and the spring feeding station. See attached document. Figure 1The workstation is located at the feeding station, and the spring feeding station corresponds to the upper cover position 8 of the workstation, that is, the spring feeding station corresponds to the pressure relief valve housing 50. The spring feeding station and the transfer station are arranged horizontally side by side. The feeding clamp 44 only needs to move up and down and laterally to send the spring from the transfer station into the pressure relief valve housing 50 of the spring feeding station. In this way, the travel of the feeding clamp 44 is short and the feeding speed is fast. The feeding clamp 44 can be a conventional pneumatic clamp. The feeding clamp 44 is mounted on the first moving seat 48. The first moving seat moves laterally and moves up and down. The lateral movement and lifting of the feeding clamp are realized by driving the first moving seat 48 to move laterally and move up and down.

[0074] The receiving part of the first receiving member 45 can be a receiving groove 49 or a receiving column. If it is a receiving column, the spring is sleeved outside the receiving column. The figure shows a receiving groove 49, that is, the receiving part is a receiving groove for receiving springs. The depth of the receiving groove 49 is less than the length of the spring. After the spring enters the receiving groove, part of the spring is outside the receiving groove, and the exposed part is clamped by the feeding clamp 44. The spring conveying component also includes a second stop member 55. The first stop member 54 is close to the outlet of the first conveying channel 43 relative to the second stop member 55. The distance between the first stop member and the second stop member 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 stop member 54 exits the first conveying channel 43, and the second stop member 55 enters the first conveying channel. After the spring is discharged, the first stop member 54 enters the first conveying channel 43, and the second stop member 55 exits the first conveying channel. Through the cooperation of the first stop member and the second stop member, one spring is output at a time. Meanwhile, to avoid the feeding clamp 44 becoming empty, which would result in the pressure relief valve housing 50 having no spring, the spring conveying component also includes a first sensor 51 for detecting whether there is material between the first stop 54 and the second stop 55, and a second sensor 52 for detecting whether there is material in the receiving groove 49 on the first receiving component 45. Both the first sensor 51 and the second sensor 52 are connected to the controller. The sensor can be a photosensitive sensor. When the first sensor 51 detects material between the first stop 54 and the second stop 55, the second stop enters the first conveying channel 43 and is blocked by the spring at the back. When the second sensor 52 detects material in the receiving groove 49 of the first receiving member 45, the feeding operation proceeds normally. When the first sensor 51 does not detect the spring, it means there is no material at the outlet. When the second sensor 52 does not detect the spring, it means there is no material in the receiving groove 49. The controller sends a command to stop the feeding operation. The feeding operation here includes the clamping and movement of the feeding clamp 44 and the rotation of the first receiving member 45, and even the operation of the electric bridge filter processing equipment. This ensures that the spring is present every time material is fed, reducing the scrap rate.

[0075] The upper valve ball device 42 includes a suction component 60, a second receiving component 58, and a valve ball conveying component. The valve ball conveying component includes a second conveying channel 56, which is inclined downwards. The outlet of the second conveying channel is at the lower position. The valve ball is spherical and can automatically move towards the outlet of the second channel due to gravity. In the figure, the second conveying channel 56 is located at the second vibrator, which further conveys the valve ball in the second conveying channel 56 to the outlet. The second receiving component 58 is located at the outlet of the second conveying channel and has a valve ball receiving groove 59 for accommodating a valve ball. The suction component 60 is located above the second receiving component 58 and moves between the valve ball picking station and the valve ball feeding station. See attached figure. Figure 1 The workstation is located at the feeding station 12, and the valve ball feeding station corresponds to the lower end cover 10 of the workstation, i.e., the valve ball feeding station corresponds to the lower end cover 23. The valve ball feeding station and the valve ball picking station are arranged horizontally side by side. The suction component 60 only needs to move up and down and laterally to send the valve ball from the valve ball picking station into the cavity of the lower end cover 23 of the valve ball feeding station. In this way, the stroke of the suction component 60 is short and the feeding speed is fast. The suction component 60 is installed on the second moving seat 40. The second moving seat 40 moves laterally and moves up and down. The up and down movement and the lateral movement of the second moving seat 40 realize the lateral movement and lifting of the suction component 60. Figure 1 In this design, the feeding clamp 44 and the suction component 60 are mounted on a single movable seat, i.e., the first movable seat 48 and the second movable seat 40 are integrated into one unit. The feeding clamp 44 and the suction component 60 move up and down and laterally synchronously, reducing the need for power components and lowering equipment costs. Figure 7-9 In the middle, the feeding clamp 44 and the suction component 60 are respectively installed on the first moving seat 48 and the second moving seat 40. The two are equipped with independent lifting and lateral movement drive components, which are independently controlled and easy to operate.

[0076] The valve ball receiving groove 59 has a first opening for the valve ball to enter and a second opening for the valve ball to exit. The first opening faces the second conveying channel 56 and is the inlet, while the second opening faces upward and is the outlet. The valve ball enters and exits the valve ball receiving groove 59 through the two openings, and the outlet is at the top, which facilitates the suction component 60 to pick up the valve ball. The second receiving member 58 moves horizontally and reciprocally perpendicular to the outlet of the second conveying channel 56. When receiving material, the first opening corresponds to the outlet of the second conveying channel 56. After receiving material, the second receiving member 58 moves horizontally and blocks the outlet of the second conveying channel. The first opening is blocked by a baffle or block on the side of the outlet of the second conveying channel 56. The second opening is at the valve ball receiving position. That is, after the valve ball enters the valve ball receiving groove 59 of the second receiving member 58, the second receiving member 58 moves relative to the second conveying channel 56, so that the outlet of the second conveying channel is misaligned with the valve ball receiving groove, providing material receiving space for the suction member 60, avoiding interference from other valve balls, and ensuring that the suction member 60 successfully adsorbs the valve ball. The second receiving component 58 is equipped with a third sensor 53 to detect 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 valve ball receiving groove, the operation proceeds normally. When the third sensor 53 does not detect the valve ball, the controller sends a command to stop the feeding operation. The feeding operation here includes the adsorption and movement of the suction component 60, and even the operation of the electric bridge filter processing equipment. This ensures that there is a valve ball every time the material is fed, reducing the scrap rate.

[0077] Both the sealing ring fitting station 13 and the second sealing ring fitting station 17 are equipped with sealing ring fitting mechanisms 2. The sealing ring fitting mechanism at the sealing ring fitting station is described as an example. The sealing ring fitting mechanism 2 includes a sealing ring conveying component 62, a sealing ring fitting component 63, and a spreading component 64. The sealing ring conveying component 62 includes a sealing ring conveying tray 65 and a material grabber 67. The sealing ring conveying tray 65 is mounted on a vibrator 71. The discharge end of the sealing ring conveying tray 65 has a clearance notch 68 for the material grabber 67 to operate. The material grabber 67 moves up and down and between the discharge end of the sealing ring conveying tray 65 and the spreading component 64. In the figure, the spreading component 64 is on the left side of the sealing ring conveying component 62. The material grabber 67 only needs to move up and down and laterally. The vibrator 71 vibrates, causing the sealing rings 61 on the sealing ring conveying tray 65 to move towards the discharge end. The sealing ring conveying tray 65 has a conveying groove 66, the width of which matches the outer diameter of the sealing ring, so that the sealing rings can move steadily towards the discharge end one by one. The discharge end of the conveying groove 66 is arc-shaped and fits the sealing ring, which can better support the sealing ring and prevent the sealing ring at the discharge end from deforming, which is conducive to the material clamp 67 picking up the sealing ring 61.

[0078] The spreading component 64 includes a material support plate 72 and several support rods 73. The support rods 73 are vertically arranged. The material support plate 72 has several sliding grooves 74 corresponding to the support rods 73 and for movement. The material support plate 72 moves up and down relative to the support rods 73. When the support rods 73 are gathered together, the circle formed is smaller than the inner diameter of the sealing ring. When the support rods 73 are dispersed, the circle formed is larger than the inner diameter of the sealing ring and the outer diameter of the sleeve 69. The support rods 73 are divided into at least three groups. The support rods 73 in the same group are mounted on a movable plate 75. The movable plates are evenly distributed on a circumference, and the movable plates 75 move radially relative to the material support plate 72. The radial movement of the movable plates 75 causes the support rods 73 to gather together or disperse. The more movable plates 75 there are, the more circular the shape formed by the support rods 73. In the figure, four movable plates 75 are provided, and three support rods 73 are installed on each movable plate 75. The three support rods 73 are distributed in an arc shape on the movable plate 75, and the 12 support rods 73 roughly form a circle. The movable plates 75 are slidably mounted on the base 78. When the four movable plates 75 are radially converged, the support rods 73 form a small circle. When the four movable plates 75 are radially dispersed, the circle formed by the support rods 73 gradually becomes larger. The material tray 72 is connected to the driving component 79 that drives its lifting and lowering. A vertically arranged guide component 77 is installed on the base 78. The material tray 72 is connected to a sliding component 76 that matches the guide component 77. The driving component 79 drives the material tray 72 to lift and lower vertically along the guide component 77.

[0079] The sealing ring assembly 63 includes a sleeve 69 and a pusher sleeve 70 fitted over the sleeve 69. The sleeve 69 moves between the sealing ring picking position and the sealing ring fitting position, while the pusher sleeve 70 rises and falls relative to the sleeve 69. The sealing ring picking position is located directly above the material support plate 72. When the sleeve 69 is in the sealing ring picking position, its bottom is flush with the top of the support rod 73, and the sleeve and the material support plate are preferably on the same center line. After the material support plate 72 pushes the sealing ring away from the support rod 73, it is directly fitted onto the sleeve 69. See attached document. Figure 10 The sealing ring fitting station and the sealing ring removal station are arranged horizontally side by side. The sleeve 69 only needs to be raised, lowered, and moved laterally. The sleeve 69 is mounted on a movable base, which is raised, lowered, and moved laterally relative to the material tray 72. The pusher sleeve 70 is raised and lowered on the movable base and is slidably disposed against the outer wall of the sleeve. The sleeve 69 is a hollow tube. When fitting the sealing ring, the hollow tube is fitted over 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 fitting on the cover plate interface 27. The sealing ring is then detached from the hollow tube and fitted onto the cover plate interface 27 at the required position.

[0080] The sealing ring fitting mechanism also includes a detection component, which includes a sensor that detects whether a sealing ring is fitted onto the cover plate interface 27. The sensor is connected to the controller. If the sensor detects a sealing ring on the cover plate interface 27, the process proceeds to the next step. If no sealing ring is detected, the sealing ring fitting operation is performed. If no sealing ring is detected after a prolonged period, the operation stops and an alarm is triggered to alert the staff, who then troubleshoot the problem. This improves the product qualification rate.

[0081] The filter paper assembly mechanism includes an adhesive applicator 6, a primary filter paper installation component 3, a flipping component 4, and a secondary filter paper installation component 5. The filter paper 22 passes sequentially through the primary filter paper installation component 3, the flipping component 4, and the secondary filter paper installation component 5. The adhesive applicator 6 applies adhesive to the mounting slots of the upper end cover 21 and the lower end cover 23. The primary filter paper installation component 3 inserts one end of the filter paper into the mounting slot of the upper end cover 21 after adhesive application, with the end without the lower end cover 23 facing upwards. The flipping component 4 rotates the filter paper with the upper end cover installed by 180 degrees, so that the end without the lower end cover faces downwards. The secondary filter paper installation component 5 inserts the other end of the filter paper into the mounting slot of the lower end cover 23 after adhesive application.

[0082] The filter paper initial installation component 3 includes a filter paper clamping assembly, a pushing assembly, and a moving frame 94. The filter paper clamping assembly and the pushing assembly are mounted on the moving 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 its 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 frustum shape, and the lower clamping opening 88 plays a tightening and guiding role. The pushing component includes a vertically movable pushing head 95, which is positioned above the upper clamping member 96 and corresponds to the upper clamping opening 87, for pushing the filter paper 22. When removing 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 closes and clamps the lower end of the filter paper, the pushing head 95 moves downward and pushes the filter paper 22, and the lower end of the filter paper passes through the lower clamping opening 88 and is tightened into the mounting groove. Specifically, the cylindrical filter paper 22 is fitted downwards onto the pressure relief valve housing 50 from above the upper end cover. When removing the filter paper, only the upper clamping member 96 clamps the upper end of the filter paper, leaving a large inner hole, so that the filter paper can be easily fitted onto the pressure relief valve housing 50. After the upper clamping member 96 clamps the filter paper, the moving frame 94 moves so that the filter paper clamped by the upper clamping member 96 is placed 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. The lower clamping member 97 closes, tightening the lower end of the loose filter paper. The inverted frustum-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 down and pushes the filter paper 22. The filter paper moves down relative to the upper clamping member 96 and the lower clamping member 97. The lower end of the filter paper is tightened and guided smoothly into the mounting groove through the lower clamping opening 88 of the lower clamping member 97, realizing the automatic assembly of the filter paper.

[0083] The inclined section 85 of the filter paper clamping part 86 extends downward from the clamping surface to a vertical section 84. 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. As the inclined section 85 at the lower end of the filter paper gradually tightens, the cylindrical vertical section 84 plays a shaping and stabilizing role, so that the filter paper part entering the mounting groove is in a tightened straight cylinder shape before entering. In this way, the shape of the filter paper part entering the mounting groove is stable and matches the mounting groove, resulting in a better assembly effect.

[0084] The first and second lower clamping heads also include an end cap clamping part 83 for clamping the end cap. The end cap clamping part 83 is located below the filter paper clamping part 86, and the clamping surface of the end cap clamping part 83 matches the side of the end cap. When the lower clamping member 97 is closed, it not only clamps the lower end of the filter paper but also clamps the upper end cap 21 together. That is, when the moving frame 94 moves, the filter paper and the upper end cap 21 move together. This allows the pressing head 95 to press the filter paper into the mounting groove of the upper end cap 21 during the movement, thereby improving the efficiency of filter paper assembly. After the filter paper 22 and the upper end cap 21 are assembled, they are moved to the shaping station 20 for shaping by the moving frame 94.

[0085] The first lower clamping head 81 and the second lower clamping head 82 move horizontally. When they move towards each other, they close; when they move away from each other, they open. The moving frame 94 is provided with a guide 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.

[0086] The movable frame 94 moves longitudinally and rises and falls vertically. The movable frame 94 is also equipped with a product-picking component 98, which is arranged longitudinally side-by-side with the filter paper clamping component. The product-picking component 98 includes a product-picking clamp. The movement of the movable frame 94 causes the filter paper clamping component and the product-picking component 98 to move synchronously. When the filter paper clamping component delivers the assembled filter paper to the shaping station 20, the product-picking component 98 picks up the shaped filter paper semi-finished product. When the filter paper clamping component picks up the upper end cap 21 or assembles the filter paper, the product-picking component 98 delivers the shaped filter paper semi-finished product to an empty filter paper station slot, thereby improving the efficiency of filter paper assembly.

[0087] The retrieval clamp includes several vertically arranged retrieval clamping heads 92, which are evenly distributed around a circumference and move radially. During clamping, the retrieval clamping heads converge towards the center; when released, they spread outwards around the circumference. The radial movement of these clamps grips the shaped filter paper semi-finished product, shortening the clamping travel distance and providing more operating space for the filter paper clamping assembly. A counterweight 25 is fitted onto the top of the filter paper 22, and the counterweight 25 is tightly fitted to the filter paper 22. The counterweight 25 keeps the filter paper in a cylindrical shape, preventing excessive looseness from affecting the clamping operation. The clamping surfaces of the retrieval clamping heads 92 are stepped, and the clamping heads grip and support the counterweight 25, resulting in better clamping performance.

[0088] The flipping component includes a clamping member 101, a steering member 102 that drives the clamping member to flip vertically, a vibrating member that drives the clamping member to move up and down reciprocally, and a lifting member that drives the clamping member to move up and down. The clamping member 101 grips and moves the filter paper semi-finished product with one end fully assembled, causing it to detach from the workpiece seat 32. The steering member 102 rotates the filter paper vertically by 180 degrees, so that the end with the counterweight 25 faces downwards. The vibrating member drives the clamping member to move up and down rapidly in short strokes, achieving a vibrating effect, causing the counterweight 25 to detach 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 downwards, delivering the flipped and counterweight-removed filter paper semi-finished product onto the workpiece seat 32.

[0089] The flipping component also includes a moving component that drives the clamping member to move horizontally. After the moving component drives the clamping member 101 to turn, it returns to its horizontal position. See attached document. Figure 16 After the filter paper semi-finished product is flipped, its horizontal position relative to the workpiece seat 32 changes. The position of the flipped filter paper semi-finished product no longer corresponds to the filter paper position on the workpiece seat 32. Therefore, the moving component resets it horizontally. This causes the lifting component to drive the clamping component downwards, and the filter paper semi-finished product returns to the filter paper removal position. The lifting component drives the clamping component to rise to the shaking station, providing operating space for the counterweight shaking process.

[0090] The steering component 102 includes a rotating shaft; the vibrating component includes a sliding plate 103 and a sliding block 104, the sliding plate reciprocating vertically on the sliding block; the moving component includes a moving seat 100, on which a horizontally arranged first guide rail 106 is provided; the lifting component includes a vertically arranged second guide rail 93; the clamping member 101 is mounted on the rotating shaft, the rotating shaft is rotatably mounted on the sliding plate 103, the sliding block 104 is slidably mounted on the first guide rail 106, and the moving seat 100 lifts and lowers on the second guide rail 93. The movement, lifting, and rotation of each component can be achieved by a cylinder drive, or by a motor combined with a lead screw mechanism, synchronous belt, gear rack, or other structures.

[0091] The filter paper secondary installation component 5 can adopt the same structure as the filter paper primary installation component 3; in addition, since the lower end cover 23 does not have a pressure relief valve housing, there is no need to consider whether the filter paper can be fitted outside the pressure relief valve housing 50. The filter paper secondary installation component 5 can use a clamping device to tighten the end of the filter paper and send it into the installation groove of the lower end cover 23.

[0092] The gluing device 6 includes a gluing component, which includes a gluing head 89. Adhesive 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. Preferably, the gluing head can move up and down; during gluing, the gluing head moves down into the mounting groove. Since the filter paper assembly is done in two stages, two sets of gluing components can be provided, one for gluing the upper end cover 21 and the other for gluing the lower end cover 23. To reduce equipment costs, only one set of gluing components is used. The gluing device 6 also includes a crossbeam 91, on which the gluing component moves laterally to the first gluing station 14 or the second gluing station 16. By moving along the crossbeam 91, the gluing component can glu two stations simultaneously, allowing both stations to share a single gluing component, thus achieving automatic gluing and reducing equipment costs.

[0093] The first gluing station 14 and the second gluing station 16 are arranged symmetrically in the horizontal direction, and a flipping station 15 is provided between the first gluing station and the second gluing station. The filter paper initial installation component 3 and the filter paper secondary installation component 5 are respectively located at the first gluing station 14 and the second gluing station 16, and the flipping component 4 is located at the flipping station 15. See attached document. Figure 1 The upper and lower end cap positions are arranged longitudinally side-by-side at the first gluing station 14 and the second gluing station 16. At the first gluing station, the gluing head 89 corresponds to the upper end cap position 8 and applies glue to the upper end cap 21. At the second gluing station 16, the gluing head 89 corresponds to the lower end cap position 10 and applies glue to the lower end cap 23. The gluing components only need to move laterally to correspond to the gluing position on the workpiece seat 32, which not only simplifies the structure and reduces equipment costs, but also allows the gluing components to be positioned more quickly.

[0094] The two ends of the filter paper 22 are respectively bonded to the upper end cap 21 and the lower end cap 23. It is best if the shape of the adhesive application matches the shape of the bonding position; therefore, a circular shape is preferable. The first and second adhesive application stations are respectively equipped with a first rotating component and a second rotating component. The first and second rotating components are located below the workpiece seat 32 and correspond to the through holes 28 of the upper end cap position 8 on the workpiece seat of the first adhesive application station 14 and the lower end cap position 10 on the workpiece seat of the second adhesive application station 16, respectively. During adhesive application, the adhesive application head 89 remains stationary. The first or second rotating component passes through the through holes of the corresponding stations, causing the upper or lower end cap of the corresponding station to rotate. The upper and lower end caps rotate relative to the adhesive application head 89, so that the adhesive extruded from the adhesive application head is applied into the mounting groove of the end cap in a circular shape. The first rotating component includes a top plate that moves up and down and a driving component that drives the top plate to rotate. The outer diameter of the top plate is smaller than the diameter of the through hole. The top plate moves upward through the through hole and pushes the upper or lower end cover of the corresponding station upward, so that the upper or lower end cover does not contact the workpiece seat 32. The driving component drives the top plate to rotate, causing the upper or lower end cover to rotate. The second rotating component can also adopt the same structure.

[0095] The cover plate assembly mechanism includes a three-axis robot 105. The three-axis robot moves laterally, longitudinally, and vertically on the frame to achieve three-axis movement. The three-axis robot 105 picks up the finished filter paper from the cover plate assembly station 18 and moves it directly above the cover plate position 19. Then, it moves down to press the bottom of the finished filter paper (i.e., the lower end cover) into the cover plate 24, completing the assembly of the electric bridge filter. The three-axis robot 105 can also pick up the assembled electric bridge filter and transfer it to the finished product area 90 for sorting.

[0096] The working principle of the preferred embodiment is further explained below with reference to 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 into the corresponding workpiece slots of the workpiece seat 32. The motor drives the sprocket 31 to rotate intermittently. Each rotation moves the transmission chain 33 one station. The workpiece seat 32 at the workpiece loading station 11 moves to the feeding station 12, and the workpiece seat 32 at the feeding station moves to the sealing ring fitting 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 slot 30 of the workpiece seat 32 at the corresponding station.

[0097] At this time, at the feeding station, the first vibrator 47 and the second vibrator vibrate, and the spring and valve ball move towards 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 baffle 54 blocks the discharge port of the first conveying channel 43, the first sensor 51 detects the spring, the second baffle 55 enters the first conveying channel and blocks the spring behind it, the receiving part of the first receiving part 45 rotates to the receiving station, the first baffle 54 exits the first conveying channel 43, the spring discharged from the discharge port enters the receiving groove 49, the first sensor 51 does not detect the spring, the second sensor 52 detects the spring, at this time the first baffle 54 enters the first conveying channel 43, the second baffle 55 exits the first conveying channel 43, the next spring enters between the first baffle 54 and the second baffle 55, when the first sensor 51 detects the spring, the second baffle 55 re-enters the first conveying channel 43. After the first receiving component 45 receives the spring, it rotates the transfer station. The feeding clamp 44 moves down to clamp the spring at the transfer station, then moves up and then laterally to the workpiece seat 32 at the feeding station. At this time, the feeding clamp 44 corresponds to the pressure relief valve housing 50 at the upper end cover. The feeding clamp 44 moves down to send the spring into the pressure relief valve housing 50. After the feeding is completed, the feeding clamp 44 moves up and laterally to reset. Similarly, the first opening of the second receiving member 58 corresponds to the outlet of the second conveying channel 56. The valve ball enters the valve ball receiving groove 59. When the third sensor 53 collects information about the valve ball, the second receiving member 58 moves horizontally to the valve ball picking position. The outlet of the second conveying channel 56 is blocked by the second receiving member 58. The suction member 60 moves down to suck up the valve ball from the second opening, then moves up and then laterally to the workpiece seat 32 above the feeding position. At this time, the feeding clamp 44 corresponds to the lower end cover 23. The suction member 60 moves down to send the valve ball into the cavity of the lower end cover 23. After feeding is completed, the suction member 60 moves up and then laterally to reset. This completes the automatic feeding of the spring and the valve ball.

[0098] At the sealing ring fitting station 13 and the second sealing ring fitting station 17, the sealing ring fitting mechanisms at the two stations respectively fit sealing rings onto the upper end cover interface 26 and the cover plate interface 27. The working principle of the two is the same. The following explanation will take the sealing ring fitting station 13 as an example. Vibrator 71 vibrates, causing the sealing rings arranged in the conveying groove 66 to move towards the discharge end. The picking clamp 67 moves down to clamp the sealing ring at the discharge end of the sealing ring conveying tray 65, and then moves up and to the right to the top of the tray 72. At this time, several support rods 73 converge. The picking clamp 67 moves down to place the sealing ring 61 on the tray and sleeve it over the support rods. After the picking clamp 67 completes the feeding, it resets. The moving plate 75 moves radially, and several support rods 73 move in the sliding groove 74, opening 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 picking position. The driving component 79 drives the tray 72 to move up, pushing the sealing ring sleeved over the support rods 73 and opened up to move up. The tray 72 and the bottom of the sleeve 69 are in contact, and the sealing ring is detached from the support rods 73 and sleeved over the sleeve. At the sealing ring fitting station of the cover plate interface, 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 fitting station. At this time, the bottom of the sleeve 69 is at the sealing ring fitting position of the cover plate interface. The pusher sleeve 70 moves down relative to the sleeve 69 and pushes the sealing ring, so that the sealing ring is detached from the sleeve 69 and fitted at the cover plate interface 27. After the sealing ring fitting is completed, the sleeve 69 moves up and moves laterally to reset, and the pusher sleeve 70 also moves up and resets.

[0099] At the first gluing station 14, the gluing head 89 moves downward, and the top plate of the first rotating component moves upward, pushing the upper end cover 21 of the first gluing station upward, so that the gluing head 89 enters or approaches the mounting groove of the upper end cover 21. The gluing head squeezes out the glue, and the top plate drives the upper end cover to rotate one revolution. After the upper end cover 21 completes the gluing, the top plate moves downward and resets, and the upper end cover is placed at the upper end cover position 8. The gluing head 89 moves upward and along the crossbeam 91 to the second gluing station 16 to apply glue to the lower end cover 23 of the second gluing station. When the upper cover 21 is being glued, the moving frame 94 of the filter paper first installation component 3 moves to the position where the filter paper is located. At this time, the pick-up clamp has already picked up the shaped filter paper semi-finished product (one end of the filter paper is bonded to the upper cover 21) from the shaping station 20. The upper clamping member 96 clamps the upper end of the filter paper, so that the filter paper retains a larger inner hole. Then the moving frame 94 moves up and then to the left to be directly above the upper cover 21. Then the moving frame 94 moves down to put the filter paper 22 on the pressure relief valve housing 50 connected to the upper cover. The lower end of the filter paper is close to the mounting groove of the upper cover 21. The lower clamping member 97 closes, the filter paper clamping part 86 clamps the lower end of the filter paper, and the end cover clamping part 83 clamps the upper cover 21. The lower end of the filter paper is tightened and the outer diameter becomes smaller. At the same time, the pick-up clamp sends the 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 moving frame 94 moves upward and to the right to the shaping station 20. During this process, the pushing head 95 moves downward, pushing the filter paper 22 downward relative to the upper clamping part 96 and the lower clamping part 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 tight. In this way, the lower end of the filter paper is smoothly tightened and guided 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 at the same time, the product picker picks up the semi-finished filter paper that has been shaped.

[0100] At the flipping station 15, the clamping member 101 clamps the filter paper semi-finished product. Then, the lifting component drives the clamping member to move upward, and the filter paper semi-finished product leaves the workpiece seat 32. The turning component 102 drives the clamping member to rotate 180 degrees clockwise, so that the counterweight 25 of the filter paper semi-finished product faces downward and the upper end cover 21 faces upward. The moving component drives the clamping member to move horizontally above the filter paper position 9. The shaking component drives the clamping member 101 to move up and down quickly and rapidly. The short-stroke rapid movement causes the counterweight 25 to detach from the filter paper. Then, the lifting component drives the clamping member to move downward, and the filter paper semi-finished product with the counterweight removed is sent to the filter paper position 9.

[0101] At the second gluing station 16, the gluing head 89 applies glue to the lower end cap 23 of the second gluing station 16. The filter paper clamping component of the filter paper secondary installation component 5 picks up the semi-finished filter paper, while the product retrieval component of the filter paper secondary installation component 5 has already picked up the shaped finished filter paper from the shaping station 20 (the other end of the filter paper is bonded to the lower end cap 23). After gluing the lower end cap, the filter paper secondary installation component 5 bonds the other end of the filter paper to the lower end cap, and the product retrieval component sends the shaped finished filter paper to the filter paper position 9; finally, the filter paper clamping component sends the bonded finished product to the shaping station 20 for shaping, while the product retrieval component picks up the shaped finished product from the shaping station.

[0102] At the cover plate assembly station, the three-axis robot 105 moves down to pick up the finished filter paper from the filter paper position, then moves up and laterally to the cover plate position 19, aligning the lower end cap of the finished filter paper with the cover plate. The three-axis robot then moves down with the finished filter paper and presses the lower end cap into the cover plate, completing the assembly of the bridge filter. Finally, the three-axis robot 105 picks up the assembled bridge filter and moves it to the finished product area 90 via its three-axis movement.

[0103] After each workstation completes its work, the rotating shaft 37 rotates in the opposite direction, the positioning wheel 35 leaves the positioning groove 30, the motor drives the sprocket 31 to rotate, and the transmission chain 33 sends the workpiece seat 32 to the next process, and so on in a cyclical manner.
