Description

Technical Field

[0001] This invention relates to the field of equipment for processing parts of intravenous infusion sets, and more specifically to an assembly and testing mechanism for air filters. Background Technology

[0002] As a crucial component of intravenous infusion sets, air filters require testing after manufacturing to ensure their effectiveness. An air filter typically consists of an upper housing, a lower housing, and filter paper. Currently, air filter components are generally injection molded and then assembled manually. This involves laying the filter paper flat inside the lower housing, then aligning the upper and lower housings to complete the assembly. After assembly, the air filter needs to be inspected to check the position of the filter paper, the presence of perforations, and the alignment of the upper and lower housings. Previously, air filter assembly was primarily done manually. After manual assembly, workers needed to observe and remove defective parts, resulting in low efficiency. Furthermore, defects in the filter paper could not be visually detected, leading to a small number of defective products in the final product. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes an assembly and testing mechanism for air filters, which facilitates rapid assembly of air filters without manual operation. Simultaneously, the air filters are tested during the assembly process, and defective products are promptly removed to prevent them from being mixed into the finished product.

[0004] To achieve the above objectives, the present invention provides an air filter assembly and testing mechanism, comprising a conveying and clamping mechanism, a filter paper clamping mechanism, a lower housing conveying mechanism, and an upper housing conveying mechanism. The lower housing conveying mechanism is located on one side of the conveying and clamping mechanism and is connected to it. Multiple rows of equally spaced clamping assemblies are arranged on the conveying and clamping mechanism to clamp the lower housing. The clamping assemblies translate on the conveying and clamping mechanism. A filter paper clamping mechanism is located above the conveying and clamping mechanism. The filter paper clamping mechanism includes a filter paper cutting assembly, a rotary adsorption assembly, and a downward pressing assembly. A filter paper take-up drum and an unwinding drum are respectively located on both sides of the filter paper cutting assembly. When the filter paper passes through the filter paper cutting assembly, multiple circular filter paper sheets are cut off. A rotary adsorption assembly is located at the bottom of the cutting component. This assembly adsorbs the filter paper sheets and transports them to the top of the lower housing. A pressing docking assembly is located on the rotary adsorption assembly, pressing the filter paper down. The rotary adsorption assembly extends into the lower housing to complete the docking of the filter paper. An upper housing conveying mechanism is located above and behind the filter paper clamping mechanism. This mechanism transports the upper housing to the top of the lower housing. A housing docking assembly is located between the upper housing conveying mechanism and the clamping component, completing the docking of the upper and lower housings. A housing detection assembly is located above the conveying clamping mechanism behind the housing docking assembly, detecting defects in the air filter. A discharge assembly is located at the end of the clamping conveying mechanism.

[0005] Preferably, the conveying and clamping mechanism includes a conveying platform and a conveyor belt. The conveyor belt, driven by rollers, is set on the conveying platform. The clamping assembly is installed on the conveyor belt by bolts. The clamping assembly is a long clamping bar with multiple clamping slots at the top for engaging the lower housing. A light is provided at the bottom of each clamping slot. The lower housing conveying mechanism is a lower housing guide rail. The lower housing guide rail is set above the clamping slots. A pressing assembly is set above the lower housing guide rail. An opening assembly is set between the lower housing guide rails. The opening assembly opens the lower housing guide rails. The opening assembly is linked with the pressing assembly.

[0006] Preferably, the filter paper cutting assembly includes a cutting platform, a lifting cutting blade, and a cutting component. The cutting platform has a rectangular through-hole for the filter paper to pass through. A lifting cutting blade is mounted on the cutting platform, and a cylinder is positioned between the lifting cutting blade and the cutting platform. The cutting blade passes through the cutting platform and extends into the rectangular through-hole. A notch is formed on the cutting blade to allow the cut circular filter paper sheets to connect. A cutting component is positioned behind the cutting platform, and a rotating suction component (a circular roller) is positioned below the cutting component. The cutting component consists of a rotating shaft and cutting blades. The rotating shaft is driven by a motor, and multiple equally spaced cutting blades are mounted on the rotating shaft. Notches are formed on the outer circumference of each cutting blade to allow space for the filter paper, thus achieving the desired filter paper connection. The components are interconnected. A cutting blade presses against the outer wall of the rotating adsorption assembly, cutting the connection between the filter paper sheets. A negative pressure suction nozzle and a telescopic tube are installed on the rotating adsorption assembly. Multiple rows of mounting holes are arranged in a ring array on the outer wall of the rotating adsorption assembly. A negative pressure suction nozzle is installed in each mounting hole, and a telescopic tube is installed on each negative pressure suction nozzle, slidingly engaging with the rotating adsorption assembly. Each row of telescopic rods is connected to the same linkage rod. A spring is installed between the linkage rod and the inner wall of the rotating adsorption assembly. The linkage rod extends outwards from both ends of the rotating adsorption assembly. Downward-pressing docking components are installed at both ends of the rotating adsorption assembly. By pressing the linkage rod with the downward-pressing docking components, the telescopic rod rises outwards, and the negative pressure suction nozzle extends into the lower housing.

[0007] Preferably, the shell docking assembly is a docking roller driven by a motor. The docking roller has multiple rows of clamping holes arranged in a circular array. Multiple vertical guide channels are provided directly above the docking roller. The bottom of the guide channels docks with the clamping holes of the docking roller, and the top of the guide channels docks with the upper shell conveying mechanism. The upper shell conveying mechanism conveys the upper shell into the guide channels. A pneumatic conveying assembly is provided at the top of the guide channels. Each clamping hole of the docking roller is nested with a docking rod. A shell adsorption assembly is installed at the outer end of each docking rod. The upper shell is adsorbed by the shell adsorption assembly. Multiple docking rods in each row of clamping holes are connected to linkage rods. The two ends of the linkage rods extend outward and protrude from the two ends of the docking roller. Pressing assemblies are provided at the two ends of the docking roller to press down the linkage rods.

[0008] Preferably, the unloading assembly includes a clamping rail, a pushing assembly, and a lifting assembly. The lifting assembly is located within the clamping slot, lifting the assembled air filter upwards. A clamping rail is positioned above the conveying clamping mechanism, divided into two halves. A swing clamping assembly is located between the two halves, with a lifting cylinder at the top of the swing clamping assembly. The lifting cylinder raises and lowers the clamping rail, while the swing clamping assembly brings the clamping rails together to clamp the air filter. A track is located inside the clamping rail, clamping the air filter. A pushing assembly is located at one end of the clamping rail, pushing the air filter on the clamping rail to one end. A storage hopper is located below the other end of the clamping rail.

[0009] Compared with the prior art, the advantages of the present invention are: it facilitates the rapid assembly of air filters without manual operation, and at the same time, the air filters are inspected during the assembly process, and defective products are promptly removed to prevent defective products from being mixed into the finished product.

[0020] The invention will now be further described with reference to the accompanying drawings.

[0021] like Figure 1-9As shown, an air filter assembly and testing mechanism includes a conveying and clamping mechanism 1, a filter paper clamping mechanism 7, a lower housing conveying mechanism 21, and an upper housing conveying mechanism 25. A rectangular outer shell is fixed to the ground on both sides of the conveying and clamping mechanism 1 by bolts. The filter paper clamping mechanism 7, the lower housing conveying mechanism 21, and the upper housing conveying mechanism 25 are all bolted onto the rectangular outer shell. The lower housing conveying mechanism 21 is located on one side of the conveying and clamping mechanism 1, and the conveying and clamping mechanism 1 is connected to the lower housing conveying mechanism 21. Multiple rows of equally spaced clamping components 2 are arranged on the conveying and clamping mechanism 1 (the clamping components 2 are multiple sets, and the multiple sets of clamping components 2 are fastened by bolts). The lower housing is clamped by the clamping assembly 2, and multiple lower housings are clamped on one clamping assembly 2. The clamping assembly 2 moves to the right on the conveying clamping mechanism 1. A filter paper clamping mechanism 7 is set above the conveying clamping mechanism 1. The filter paper clamping mechanism 7 is located to the right of the lower housing conveying mechanism 21. After the clamping assembly 2 clamps the lower housing, the filter paper is fed. The filter paper clamping mechanism 7 includes a filter paper cutting assembly 8, a rotary adsorption assembly 14 and a downward pressing docking assembly 18. A filter paper take-up drum 19 and an unwinding drum 20 are respectively set on both sides of the filter paper cutting assembly 8. The filter paper to be cut is unwound through the unwinding drum 20. The cut waste paper is then unwound through the unwinding drum 20. The filter paper is wound up via the take-up drum 19, whose main shaft is driven by a motor. When the filter paper passes through the filter paper cutting assembly 8, multiple circular filter paper sheets are cut off. A rotary adsorption assembly 14 is located at the bottom of the filter paper cutting assembly 8. The rotary adsorption assembly 14 adsorbs the circular filter paper sheets and transports them to the top of the lower housing. A pressing docking assembly 18 is located on the rotary adsorption assembly 14. The pressing docking assembly 18 presses the filter paper down and inserts it into the lower housing, completing the assembly of the filter paper and the lower housing. Thus, the filter paper at the bottom of the rotary adsorption assembly 14 extends into the lower housing, completing the filter paper assembly. In the filter paper clamping mechanism... 7. An upper housing conveying mechanism 25 is provided on the upper right side. The upper housing is conveyed to the upper housing above the lower housing. A housing docking assembly 26 is provided between the upper housing conveying mechanism 25 and the clamping assembly 2. The upper housing is pressed into the lower housing by the housing docking assembly 26, thus completing the assembly. The upper housing and the lower housing are docked by the housing docking assembly 26. A housing detection assembly 33 is provided above the conveying clamping mechanism 1 on the right side of the housing docking assembly 26. The housing detection assembly 33 detects whether there are defects in the air filter. A discharge assembly 34 is provided at the end of the clamping conveying mechanism. The discharge assembly 34 discharges the air filter on the clamping assembly 2.

[0022] The conveying clamping mechanism 1 includes a conveying platform 3 and a conveyor belt 4 (the conveying clamping mechanism 1 includes a conveying platform 3 and a conveyor belt 4, wherein multiple sets of rollers connected to the conveyor chain are installed on the conveying platform 3 via bearings, and the rollers are driven by a motor, thus realizing the movement of the conveyor belt 4). A conveyor belt 4 driven by rollers is provided on the conveying platform 3. The clamping assembly 2 is installed on the two conveyor belts 4 by bolts. The clamping assembly 2 is a long, strip-shaped clamping bar, with multiple clamping slots 5 at the top of the clamping bar that engage with the lower housing (the inner wall of the clamping slot 5 fits against the outer wall of the lower housing). An upward-emitting light is embedded at the bottom of each clamping slot 5. The lighting lamp 6 illuminates the bottom of the air filter during the inspection of the housing inspection component 33. The housing inspection component 33 is an industrial camera connected to a computer. By analyzing the images captured by the housing inspection component 33 (filter paper misalignment, filter paper gaps, and filter paper holes), the computer compares and identifies defective products. The lower housing conveying mechanism 21 is a lower housing guide rail 22. The lower housing guide rail 22 is set above the clamping slot 5 (the lower housing guide rail 22 is divided into two halves, and multiple lower housings are placed on the lower housing guide rail 22 for conveying). A pressing component 23 is set above the lower housing guide rail 22. An opening assembly 24 is provided between the housing guide rails 22. The opening assembly 24 consists of two bidirectional cylinders. A suspension rod is fixed to the top of the bidirectional cylinder by welding, and the suspension rod is also fixed to the inner top of the housing by welding. The two bidirectional cylinders are located directly above both ends of the lower housing guide rails 22. The piston rods of the bidirectional cylinders are respectively connected to the two lower housing guide rails 22 by welding. A pressing assembly 23 is installed on the cylinder body of each bidirectional cylinder by bolt fastening. The pressing assembly 23 is a pressing cylinder with the piston rod of the pressing cylinder pointing downwards. A pressing plate is fixed to the piston rod of the two pressing cylinders by welding. Located directly above the lower housing guide rail 22, the lower housing guide rail 22 is opened by the opening component 24. The opening component 24 is linked with the pressing component 23. When the opening component 24 slowly opens, the pressing component 23 slowly presses down, thus clamping the lower housing in the clamping groove 5. The lower housing guide rail 22 is connected to the rail for conveying the lower housing. Multiple lower housings arranged side by side are conveyed on the rail. A push plate driven by a cylinder is installed on the rail. The push plate pushes the lower housings on the rail onto the lower housing guide rail 22. The rail passes through the outer shell and extends into the outer shell. The rail and the outer shell are connected by welding.

[0023] The filter paper cutting assembly 8 includes a cutting platform 9, a lifting cutting blade 10, and a cutting component 11. The cutting platform 9 has a rectangular through hole for the filter paper to pass through. The cutting platform 9 is bolted to the housing. The lifting cutting blade 10 (which consists of multiple longitudinally arranged circular blades connected by welding, cutting circular pieces of filter paper from the filter paper) is mounted on the cutting platform 9. A cylinder is welded between the lifting cutting blade 10 and the cutting platform 9, raising and lowering the cutting blade 10. Platform 9 extends into the rectangular through hole and has notches on the cutting blade, so that the cut circular filter paper pieces can be connected to each other. At the same time, the circular filter paper pieces on both sides are connected to the waste filter paper, so that the circular filter paper pieces move with the filter paper. A cutting assembly 11 is set on the right side of the cutting platform 9, and a rotating adsorption assembly 14 is set below the cutting assembly 11. The rotating adsorption assembly 14 is a circular roller, and the two ends of the circular roller are mounted on the inner wall of the outer shell through bearings. The circular roller is driven by a motor. The cutting assembly 11 consists of a rotating shaft 12 and a cutting blade 13, wherein the rotating shaft 12 is driven by a motor.The two ends of the rotating shaft 12 are mounted on the inner wall of the housing via bearings. Multiple equally spaced cutting blades 13 (the spacing between the cutting blades 13 is the diameter of the circular filter paper) are bolted onto the rotating shaft 12. Notches are cut into the outer circumference of each cutting blade 13 to allow space for the filter paper, thus connecting the filter paper pieces (only cutting the joints between the circular filter paper pieces and the joints between the two circular filter paper pieces on either side). The cutting blades 13 press against the outer wall of the rotating adsorption assembly 14, thereby cutting off the joints between the circular filter paper pieces. The circular filter paper is adsorbed onto the rotary adsorption assembly 14. A negative pressure suction nozzle 15 and a telescopic tube 16 are installed on the rotary adsorption assembly 14. Multiple rows of mounting holes 17 are formed on the outer wall of the rotary adsorption assembly 14, with the positions of the mounting holes 17 corresponding to the positions of the circular filter paper and the clamping groove 5. The multiple rows of mounting holes 17 are arranged in a ring array. A negative pressure suction nozzle 15 is embedded in each mounting hole 17, and a telescopic tube 16 is fixed to each negative pressure suction nozzle 15 by welding, with the telescopic tube 16 slidingly engaging with the rotary adsorption assembly 14. The circular roller is hollow inside. The telescopic tube 16 passes through the inner wall of the circular roller and extends into the circular roller. Each row of telescopic rods is connected to the same linkage rod by welding. A spring is fixed between the linkage rod and the inner wall of the rotary adsorption assembly 14 by welding (the spring enables the negative pressure suction nozzle 15 to retract into the mounting hole 17). The linkage rod extends out of both ends of the rotary adsorption assembly 14 (multiple rectangular slots arranged in a ring array are opened at both ends of the circular roller, and the linkage rod protrudes from both ends of the circular roller through the rectangular slots). Downward pressing docking assemblies 18 are provided at both ends of the rotary adsorption assembly 14. The connecting component 18 is a cylinder, which is installed on the outer shell by bolts. By pressing down the connecting component 18, the linkage rod rotated to the bottom is pressed, so that the telescopic rod is pushed outward, and the negative pressure suction nozzle 15 extends into the lower shell. At the same time, the filter paper adsorbed by the negative pressure suction nozzle 15 also extends into the lower shell. At the same time, the negative pressure suction nozzle 15 ends the negative pressure state and separates from the filter paper, so that the filter paper remains in the lower shell. The negative pressure suction nozzle 15 is connected to the negative pressure pump through a pipe. When the negative pressure suction nozzle 15 extends into the lower shell, the negative pressure pump is disconnected from the negative pressure suction nozzle 15 located at the bottom.

[0024] The housing docking assembly 26 is a docking roller 27 driven by a motor. Both ends of the docking roller 27 are mounted on the housing via bearings. The docking roller 27 is driven to rotate by the motor. Multiple rows of clamping holes 28 arranged in a circular array are formed on the docking roller 27. The clamping holes 28 correspond vertically to the clamping grooves 5. Multiple vertical guide channels 29 are provided directly above the docking roller 27 (each guide channel 29 communicates with the clamping holes 28). The bottom of the guide channel 29 connects to the clamping holes 28 of the docking roller 27, and the top of the guide channel 29 connects to the upper housing conveying mechanism 25 (the upper housing conveying mechanism 25 connects to the upper housing conveying mechanism 25). The conveying mechanism 25 consists of multiple transverse tracks. The upper housing is placed top-down on the tracks for conveying. The tracks pass through the outer wall of the guide channel 29 and connect to the inside of the guide channel 29. The upper housing on the tracks flows into the guide channel 29 and falls into the clamping hole 28 for clamping. The upper housing conveying mechanism 25 conveys the upper housing into the guide channel 29. A pneumatic conveying assembly 30 (an air pump) is fixed to the top of the guide channel 29 by welding. Each clamping hole 28 of the docking roller 27 is nested with a docking rod 31 for docking. Roller 27 is also a hollow roller. The connecting rod 31 passes through the inner wall of the connecting roller 27 and extends into the hollow cavity. A housing adsorption assembly 40 is welded to the outer end of each connecting rod 31. (The housing adsorption assembly 40 is cylindrical; the outer surface of the cylinder contacts the inner surface of the clamping hole 28. A groove for embedding the upper housing is opened on the outer surface of the cylinder, and the groove contacts the outer wall of the upper housing. A negative pressure hole is opened at the bottom of the groove, and the negative pressure hole is connected to a negative pressure pump through a pipe, thus keeping the groove under negative pressure.) The upper housing is adsorbed by the housing adsorption assembly 40. Multiple rods in each row of clamping holes 28... The docking rod 31 and the linkage rod are connected by welding. The two ends of the linkage rod extend outward and protrude from the two ends of the docking roller 27 (rectangular grooves arranged in a ring array are also opened at both ends of the docking roller 27, and the linkage rod also extends out of the docking roller 27 through the rectangular grooves). At both ends of the docking roller 27, there are pressing components 32 that press down the linkage rod. The pressing components 32 are also pressing cylinders. The pressing cylinders press down the linkage rod, so that the housing adsorption component 40 is lifted outward, and the upper housing and the lower housing are docked. The negative pressure pump is disconnected from the housing adsorption component 40 located at the bottom.

[0025] The unloading assembly 34 includes a clamping rail 35, a pushing assembly 37, and a lifting assembly 38. Each clamping slot 5 is equipped with a lifting assembly 38 (the lifting assembly 38 is a lifting cylinder; the piston rod of the lifting cylinder extends from the bottom of the housing to the bottom of the clamping slot 5, and the air filter is raised by the lifting of the lifting assembly 38; when a defective product is detected, the corresponding lifting assembly 38 in the clamping slot 5 is lifted). The lifting assembly 38 lifts the assembled air filter upwards. A clamping rail 35 is provided above the conveying clamping mechanism 1. The clamping track 35 is divided into two halves, and a swing clamping assembly 36 is provided between the two halves of the clamping track 35 (the swing clamping assembly 36 includes a swing arm and a swing cylinder; the top of each clamping track 35 is fixed to the swing arm by welding; the two swing arms are hinged to the same fixed rod; a swing cylinder is hinged between the fixed rod and the swing arm; the swing cylinder achieves the clamping of the air filter by clamping the track 35). A lifting cylinder is provided on the top of the swing clamping assembly 36 (the cylinder body of the lifting cylinder is installed on the top of the housing by bolts). The piston rod of the lifting cylinder is connected to the fixed rod by bolts. The lifting cylinder raises and lowers the clamping rail 35. After the clamping rail 35 clamps the outer wall of the air filter, the rising of the lifting cylinder completely separates the air filter from the clamping slot 5. The swing clamping assembly 36 brings the clamping rails 35 together and clamps the air filter. A track 39 is provided on the inner side of the clamping rail 35 (the track 39 is installed on the inner side of the clamping rail 35 through bearings). The track 39 clamps the air filter. The clamping mechanism is configured with a pusher assembly 37 at one end of the clamping track 35. The pusher assembly 37 is a cylinder, and the cylinder body is fastened to the outer casing with bolts. The piston rod of the pusher cylinder extends into the clamping track 35, and the air filter on the clamping track 35 is pushed to one end by the pusher assembly 37. A storage hopper is set on the ground below the other end of the clamping track 35 for receiving materials. The housing detection assembly 33 is connected to the PLC through wires, and the PLC is connected to multiple lifting assemblies 38 through wires.
