Description

Technical Field

[0001] The present invention relates to the technical field of O-ring assembly, and particularly to an O-ring assembly machine. Background Art

[0002] O-rings are widely used in various equipment in all walks of life due to their good sealing performance, compact structure, long service life, small frictional resistance, simple manufacturing, convenient disassembly and assembly, and low cost. Therefore, when some products are produced, corresponding O-rings need to be assembled. In order to improve the assembly efficiency, assembly equipment is used for assembly.

[0003] In the prior art, a Chinese invention patent with the publication number CN107900635A discloses an O-ring assembly device, which is characterized in that: it includes a frame, a product feeding device, an O-ring feeding device and an assembly device. The assembly device includes a driving mechanism and an assembly mechanism. The assembly mechanism includes a vertical plate, a mounting plate, a material grabbing part, a first telescopic cylinder, a second telescopic cylinder and a support rod. The material grabbing part is mounted on the mounting plate. The material grabbing part is a cylindrical hollow structure. A plurality of through grooves are provided on the outer edge surface of the bottom of the material grabbing part. The through grooves make the bottom of the material grabbing part form a plurality of arc-shaped pieces evenly distributed in a ring shape. The first telescopic cylinder and the second telescopic cylinder are mounted on the vertical plate. The top of the support rod is connected to the output shaft of the second telescopic cylinder, and the bottom of the support rod is inserted into the material grabbing part. A collar is further provided outside the plurality of arc-shaped pieces. The collar is connected to the first telescopic cylinder through a connecting device. It uses the material grabbing part to grab the O-ring, and then uses the cylindrical head on the support rod to expand the material grabbing part, that is, expand the diameter of the O-ring, and then directly install the expanded O-ring on the product.

[0004] When the above solution is implemented, it grabs the O-ring through the set material grabbing part and slews it on the product. It mainly performs the installation operation through a single O-ring. The entire installation process takes a long time. When mass production is required, multiple material grabbing parts need to work simultaneously. At this time, the feeding speed of the O-ring is also difficult to meet the production requirements of multiple material grabbing parts, thus affecting the production efficiency of the product. Summary of the Invention

[0005] Based on this, in view of the above technical problems, it is necessary to provide an O-ring assembly machine. When assembling, by automatically transporting the components and the corresponding O-rings to the double-disk convergence point, at this time, the corresponding top extension cylinder moves upward to push the O-ring onto the component, thereby achieving the purpose of automatic installation, realizing the purpose of automatically feeding different components in sequence and automatically assembling, and improving the assembly quality and assembly efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An O-ring assembly machine, which includes: Workbench; Component feeding tray, installed on the workbench for feeding components, and a component guiding track is provided at the output end of the component feeding tray; O-ring feeding tray, installed on the workbench for feeding O-rings. A vertically installed O-ring guiding cylinder is provided at the output end of the O-ring feeding tray. An O-ring guiding disk rotatably connected to the workbench is provided below the O-ring guiding cylinder. An O-ring positioning groove matching the bottom output end of the O-ring guiding cylinder is provided on the outer ring of the O-ring guiding disk; Assembly table, installed on the workbench for assembling O-rings on components. The assembly table includes an assembly seat rotatably connected to the workbench, a plurality of top-extending cylinders vertically inserted along the outer ring of the assembly seat, a component positioning groove provided on the outer ring of the assembly seat and corresponding to the top of the top-extending cylinders, and an installation track sleeved on the bottom of the assembly seat. The top surface of the installation track abuts against the bottom of the top-extending cylinders, and the bottom surface of the installation track is connected to the workbench. When the top-extending cylinders slide along the top surface of the installation track, they move up and down periodically. The output end of the O-ring positioning groove extends to the component positioning groove. The intersection of the component positioning groove provided on the outer ring of the assembly seat and the O-ring positioning groove provided on the outer ring of the O-ring guiding disk is the double-disk convergence point; Product discharging track, provided on the workbench, and the input end of the product discharging track corresponds to the downstream of the double-disk convergence point on the assembly seat for discharging the assembled product.

[0007] As a preferred embodiment of the O-ring assembling machine provided by the present invention, a control gear is installed at the bottom of the assembly seat, and a driving gear is meshed with the outer ring of the control gear. The driving gear is installed on the output shaft of the driving component. By driving the driving gear to rotate through the driving component, the control gear and the assembly seat are driven to rotate, so that the top-extending cylinders move along the upper surface of the installation track as the assembly seat rotates. The driving component is preferably a driving motor or a pneumatic motor.

[0008] As a preferred embodiment of the O-ring assembling machine provided by the present invention, the bottom of the top-extending cylinder is a sliding part that slides with the installation track, and the top of the top-extending cylinder is a top rod part that matches the O-ring. When the top-extending cylinder slides along the installation track to the double-disk convergence point, its top rod part performs an upward pushing movement on the O-ring in the O-ring positioning groove, and after the O-ring is pushed up by the top rod part, it is installed with the component installation position at the double-disk convergence point. When the top-extending cylinder moves driven by the rotation of the assembly seat, the sliding part at the bottom of the top-extending cylinder moves along the upper surface of the installation track and moves up and down with the height of the upper surface of the installation track. The top rod part at the top of the top-extending cylinder is used to push up the O-ring that moves to the double-disk intersection point and assemble the O-ring with the component installation position.

[0009] As a preferred embodiment of the O-ring assembling machine provided by the present invention, both the component feeding tray and the O-ring feeding tray are vibrating trays, which are used to automatically sort and feed the corresponding materials, so as to achieve the purpose of automatically sorting and feeding the components and O-rings.

[0010] As a preferred embodiment of the O-ring assembling machine provided by the present invention, a defective product detection mechanism is arranged on the O-ring guiding cylinder. The defective product detection mechanism includes an O-ring positioning groove fixed to the O-ring guiding cylinder, a turning seat horizontally rotatably connected to the O-ring positioning groove, and a hydraulic pipe inserted in the middle of the turning seat. The hydraulic pipe is externally connected to a hydraulic pump. The end of the turning seat extends into the inner cavity of the O-ring guiding cylinder. Detection cylinders matching the O-rings are arranged at both the upper and lower ends of the turning seat. The detection cylinders are placed inside the O-ring guiding cylinder. Each detection cylinder is horizontally provided with a detection hole, and detection ejector rods are inserted at both ends of the detection hole. A communication hole is opened in the upper part of the front end of the hydraulic pipe. Each detection hole is connected to a pipe matching the communication hole on the hydraulic pipe. When the O-rings sorted and fed in sequence enter the O-ring guiding cylinder and fall along its inner cavity, the O-rings will be blocked by the turning seat first and sleeved on the detection cylinder located above the turning seat. During detection, the hydraulic pump works to pump hydraulic oil into the hydraulic pipe, and the hydraulic oil enters the pipe through the communication hole in the upper part of the front end of the hydraulic pipe and enters the corresponding detection hole through the pipe. The hydraulic oil pushes the detection ejector rods to move towards both ends, pushing the O-ring sleeved on the outer circle of the detection cylinder to expand, so as to detect the expansion effect of the O-ring, whether it can reach the normal O-ring expansion effect, so as to judge whether the corresponding O-ring is damaged. After the detection is completed, the hydraulic oil is controlled to flow reversely to reset, and the detection ejector rods are controlled to reset to release the support for the O-ring. At this time, by controlling the rotation of the turning seat, the detected O-ring is turned downward, and the O-ring falls to the next process by gravity, so as to achieve the purpose of detecting each O-ring passing through the O-ring guiding cylinder.

[0011] As a preferred embodiment of the O-ring assembling machine provided by the present invention, a return spring is installed between the two detection ejector rods corresponding to each detection cylinder. The outer circle of the top of the detection cylinder is chamfered. The detection cylinder is convenient for assisting in controlling the reset of the two detection ejector rods and releasing the locking of the O-ring. The chamfer design is convenient for each O-ring to be sleeved on the outer circle of the corresponding detection cylinder, which is convenient for accurate detection.

[0012] As a preferred embodiment of the O-ring assembling machine provided by the present invention, a detection annular groove is formed in the inner wall of the O-ring guide cylinder. The detection annular groove is located at the outer circle of the detection cylinder above the flipping seat. A proximity switch corresponding to each detection ejector rod is installed on the inner wall of the detection annular groove. The detection annular groove can provide a movement space for the outward expansion detection of the O-ring. When the two detection ejector rods extend outward to push the O-ring for outward expansion detection, the O-ring contacts the proximity switch, and the proximity switch can detect whether the O-ring expands to the specified position, which is convenient for improving the accuracy of detection.

[0013] As a preferred embodiment of the O-ring assembling machine provided by the present invention, a driving member is installed on the O-ring positioning groove. The output end of the driving member is rotationally connected to the flipping seat through a gear ring. An electromagnetic valve is installed in the hydraulic pipe. A pressure sensor is embedded at the end of the hydraulic pipe. An assembly intelligent controller is further arranged on the workbench. A defective product detection module, a processing module and a reminder module are arranged on the assembly intelligent controller. The defective product detection module is respectively signal-connected to an analysis module, a proximity switch, an electromagnetic valve, a pressure sensor and a hydraulic pump. The processing module is respectively signal-connected to the reminder module and the driving member. The reminder module is signal-connected to a warning lamp. The warning lamp is installed on the outer shell of the assembly intelligent controller. After the O-ring expands, it will generate a certain reaction force on the detection ejector rod and push the detection ejector rod in the reverse direction to extrude the hydraulic oil in the detection hole. When the O-ring is damaged, the reaction force generated by its expansion on the detection ejector rod decreases, so that the pressure data detected by the pressure sensor will also be lower than the pressure data when the O-ring is not damaged. When detecting the defect of each O-ring entering the O-ring guide cylinder, the O-ring is sleeved on the detection cylinder. At this time, the defective product detection module controls the hydraulic pump to work to increase the pressure in the hydraulic pipe and controls the electromagnetic valve to open. The hydraulic oil enters the detection hole and pushes the two detection ejector rods to extend to push the O-ring to expand outwards. When the O-ring expands outwards and contacts the proximity switch, the proximity switch sends the detected position signal to the defective product detection module. The defective product detection module judges that the O-ring has expanded to the specified position. At this time, the defective product detection module will control the electromagnetic valve to close and the hydraulic pump to stop working, so that the hydraulic oil pressure of a section of the hydraulic pipe close to the pipeline of the electromagnetic valve in the hydraulic pipe remains constant. At this time, the pressure sensor feeds back the pressure data of the hydraulic pipe to the defective product detection module. At the same time, the defective product detection module controls the electromagnetic valve to open to relieve the pressure of the hydraulic pipe and reset. At this time, the detection ejector rod and the O-ring are reset; the defective product detection module sends the pressure data to the processing module. The processing module compares the pressure data detected by the pressure sensor with the normal pressure data (the normal pressure data corresponding to the qualified O-ring is preset in the processing module). When it is judged that the pressure data is the same as the normal pressure data, the processing module judges that the corresponding O-ring is qualified. The processing module controls the driving member to work to drive the flipping seat to flip, and the corresponding O-ring is flipped downward and falls along the O-ring guide cylinder; when it is judged that the pressure data is less than the normal pressure data, the processing module judges that the corresponding O-ring is unqualified. The processing module sends an unqualified reminder signal to the reminder module. The reminder module controls the warning lamp to work and emits an unqualified reminder light for the staff to process. And the processing module controls the driving member to work to drive the flipping seat to flip, and the corresponding O-ring is flipped downward and discharged for the staff to process.

[0014] As a preferred embodiment of the O-ring assembling machine provided by the present invention, a defective product discharging mechanism is further arranged on the O-ring positioning groove. The defective product discharging mechanism includes a defective product guiding plate horizontally inserted into the O-ring guiding cylinder and a telescopic member installed on the O-ring positioning groove. The output end of the telescopic member is installed with the defective product guiding plate. The defective product guiding plate is arranged below the flipping seat. The processing module is signal-connected to the telescopic member. When the processing module determines that the corresponding O-ring is unqualified, the processing module sends a reminder signal of unqualified to the reminder module. The reminder module controls the warning light to work and emits a reminder light of unqualified. At the same time, the processing module controls the telescopic member to work. The telescopic member drives the defective product guiding plate to insert into the O-ring guiding cylinder. When the processing module controls the driving member to work and drive the flipping seat to flip, and discharges the corresponding O-ring downward, the corresponding O-ring will be intercepted by the defective product guiding plate and discharged to the waste collection place along the defective product guiding plate, realizing the functions of automatic detection and automatic screening of defective products and reducing the labor intensity of personnel.

[0015] As a preferred embodiment of the O-ring assembling machine provided by the present invention, one end of the defective product guiding plate close to the O-ring guiding cylinder is inclined. A defective product dropping groove is opened at the end of the defective product guiding plate far from the O-ring guiding cylinder. The O-ring falls onto the defective product guiding plate and falls into the defective product dropping groove along the inclined defective product guiding plate and is discharged from the defective product dropping groove, realizing the functions of automatic detection and automatic screening of defective products.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. For the O-ring assembling machine provided by the present invention, during assembly, after the components are automatically sorted and loaded, they enter the component positioning groove on the assembly seat through the component guiding track, and as the assembly seat rotates, the components on the component positioning groove are gradually and automatically transported to the double-disk convergence point. At the same time, after the O-rings are automatically sorted and loaded, they enter the O-ring guiding cylinder and sequentially fall onto the O-ring positioning grooves on the O-ring guiding disk. Through the rotation of the O-ring guiding disk, the O-rings located on the O-ring positioning grooves are sequentially transported to the double-disk convergence point. When the component and the corresponding O-ring both move to the double-disk convergence point, the corresponding bottom jacking cylinder moves upward as the height of the top edge of the installation track changes. At this time, the jacking cylinder jacks upward to push the O-ring onto the component, thus achieving the purpose of automatic installation. And as the assembly seat and the O-ring guiding disk continue to rotate, the assembled products are sequentially moved to the next process, and the components and O-rings to be installed are moved to the double-disk convergence point for automatic assembly, thus achieving the purpose of automatically feeding different components in sequence and automatically assembling them, improving the assembly quality and assembly efficiency.

[0017] 2. When the O-rings fed in sequence enter the O-ring guide tube and fall along its inner cavity, the O-rings will first be blocked by the flipping seat and sleeved on the detection tube located above the flipping seat. When conducting the detection, the hydraulic pump works to flush hydraulic oil into the hydraulic tube, and the hydraulic oil enters the pipeline through the communication hole at the upper part of the front end of the hydraulic tube, and then enters the corresponding detection holes through the pipeline. The hydraulic oil pushes the detection ejector rod to move towards both ends, pushing the O-ring sleeved on the outer ring of the detection tube to expand, so as to detect the expansion effect of the O-ring, whether it can reach the normal O-ring expansion effect, thereby judging whether the corresponding O-ring is damaged. After the detection is completed, the hydraulic oil is controlled to flow reversely to reset, and the detection ejector rod is controlled to reset to release the support for the O-ring. At this time, by controlling the rotation of the flipping seat, the detected O-ring is flipped downward, and the O-ring falls to the next process by gravity, achieving the purpose of detecting each O-ring passing through the O-ring guide tube.

It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0023] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Embodiment

[0024] Please refer to Figures 1-5, an O-ring assembling machine, comprising a workbench 1, a component feeding tray 2, an assembling table 3, an O-ring feeding tray 4 and a product discharging track 11; the component feeding tray 2 is installed on the workbench 1 for feeding components. A component guiding track 8 is arranged at the output end of the component feeding tray 2. The component feeding tray 2 is used for automatically sorting and feeding components and conveying them through the component guiding track 8; the O-ring feeding tray 4 is installed on the workbench 1 for feeding O-rings. An O-ring guiding cylinder 9 is vertically installed at the output end of the O-ring feeding tray 4. An O-ring guiding disk 6 rotatably connected to the workbench 1 is arranged below the O-ring guiding cylinder 9. An O-ring positioning groove 18 matching the bottom output end of the O-ring guiding cylinder 9 is formed in the outer ring of the O-ring guiding disk 6. The O-ring feeding tray 4 automatically sorts and feeds O-rings and conveys them to the O-ring guiding cylinder 9. The O-rings fall into the O-ring positioning grooves 18 of the O-ring guiding disk 6 at the bottom through the O-ring guiding cylinder 9. During the continuous rotation of the O-ring guiding disk 6, the O-rings sequentially fall onto the O-ring positioning grooves 18; It is worth mentioning that, please refer to Figure 4 and Figure 5 , the assembling table 3 is installed on the workbench 1 for assembling O-rings on components. The assembling table 3 includes an assembling seat 16 rotatably connected to the workbench 1, a plurality of top-extending cylinders 15 vertically inserted along the outer ring of the assembling seat 16, a component positioning groove 17 formed in the outer ring of the assembling seat 16 and corresponding to the top of the top-extending cylinders 15, and an installation track 14 sleeved on the bottom of the assembling seat 16. The top surface of the installation track 14 abuts against the bottom of the top-extending cylinders 15, and the bottom surface of the installation track 14 is connected to the workbench 1. When the top-extending cylinders 15 slide along the top surface of the installation track 14, they move up and down periodically. When the assembling seat 16 rotates, it drives the plurality of top-extending cylinders 15 to rotate around the axis of the assembling seat 16, thereby driving the plurality of top-extending cylinders 15 to move along the top surface of the installation track 14 and move up and down as the surface height of the installation track 14 changes. The output end of the O-ring positioning groove 18 extends to the component positioning groove 17. The intersection of the component positioning groove 17 formed in the outer ring of the assembling seat 16 and the O-ring positioning groove 18 formed in the outer ring of the O-ring guiding disk 6 is the double-disk convergence point.

[0025] During assembly, after the components are automatically sorted and fed, they enter the component positioning groove 17 on the assembly seat 16 through the component guide rail 8, and as the assembly seat 16 rotates, the components on the component positioning groove 17 are gradually and automatically transported to the double-disk convergence point. At the same time, after the O-rings are automatically sorted and fed, they enter the O-ring guide cylinder 9 and sequentially fall onto the O-ring positioning grooves 18 on the O-ring guide disk 6. The rotation of the O-ring guide disk 6 transports the O-rings located on the O-ring positioning grooves 18 to the double-disk convergence point in sequence. When the components and the corresponding O-rings both move to the double-disk convergence point, the corresponding bottom jacking cylinder 15 moves upward as the height of the top edge of the installation rail 14 changes. At this time, the jacking cylinder 15 jacks upward to push the O-ring onto the component, thus achieving the purpose of automatic installation. Along with the continuous rotation of the assembly seat 16 and the O-ring guide disk 6, the assembled products are sequentially moved to the next process, and the components and O-rings to be installed are moved to the double-disk convergence point for automatic assembly, thereby achieving the purpose of automatically feeding different components in sequence and automatically assembling them, improving the assembly quality and assembly efficiency.

[0026] Moreover, the product discharge rail 11 is arranged on the workbench 1. The input end of the product discharge rail 11 corresponds to the downstream of the double-disk convergence point on the assembly seat 16 and is used to discharge the assembled products. After the components and O-rings are assembled, the assembled products will be transported to the product discharge rail 11 as the assembly seat 16 rotates and are discharged along with the product discharge rail 11, thus achieving the purpose of assembly and discharging. The component feeding tray 2 and the O-ring feeding tray 4 are both vibrating trays, which are used to automatically sort and feed the corresponding materials, achieving the purpose of automatically sorting and feeding the components and O-rings.

[0027] In this embodiment, please refer to Figure 4 and Figure 5, a control gear 13 is installed at the bottom of the assembly seat 16. The outer ring of the control gear 13 meshes with a driving gear 12. The driving gear 12 is installed on the output shaft of the driving assembly. The driving assembly drives the driving gear 12 to rotate, and drives the control gear 13 and the assembly seat 16 to rotate, so that the top extension cylinder 15 rotates along the upper surface of the installation track 14 as the assembly seat 16 rotates. The driving assembly is preferably a driving motor or a pneumatic motor. The bottom of the top extension cylinder 15 is a sliding part that slides with the installation track 14, and the top of the top extension cylinder 15 is a top rod part that matches the O-ring. When the top extension cylinder 15 slides along the installation track 14 to the double-disk convergence point, its top rod part performs an upward pushing movement on the O-ring in the O-ring positioning groove 18, and after the O-ring is pushed up by the top rod part, it is installed with the component installation position at the double-disk convergence point. When driving the top extension cylinder 15 to move by rotating the assembly seat 16, the bottom sliding part of the top extension cylinder 15 moves along the upper surface of the installation track 14 and moves up and down with the height of the upper surface of the installation track 14. The top rod part at the top of the top extension cylinder 15 is used to push up the O-ring that moves to the double-disk intersection point, and assemble the O-ring with the installation position of the component. Embodiment

[0028] Further optimize an O-ring assembling machine provided in the first embodiment. Different from the first embodiment, when feeding O-rings in sequence, due to damage during the feeding process of the O-ring raw material and through the vibrating disk, the damaged O-ring is difficult to detect after being installed on the component, which will also affect the sealing performance of the product. To solve the above problems, please refer to Figures 6-8 , a defective product detection mechanism 10 is provided on the O-ring guiding cylinder 9. The defective product detection mechanism 10 includes an O-ring positioning groove 18 fixed to the O-ring guiding cylinder 9, a flipping seat 19 horizontally rotatably connected to the O-ring positioning groove 18, and a hydraulic pipe 23 inserted in the middle of the flipping seat 19. The hydraulic pipe 23 is externally connected to a hydraulic pump. The end of the flipping seat 19 extends into the inner cavity of the O-ring guiding cylinder 9. Detection cylinders 20 that match the O-ring are provided at both the upper and lower ends of the flipping seat 19. The detection cylinders 20 are placed inside the O-ring guiding cylinder 9. Each detection cylinder 20 is horizontally provided with a detection hole, and detection ejector rods 21 are inserted at both ends of the detection hole. A communication hole is opened in the upper part of the front end of the hydraulic pipe 23. Each detection hole is connected to a pipe 30 that matches the communication hole on the hydraulic pipe 23. When the O-rings fed in sequence enter the O-ring guiding cylinder 9 and fall along its inner cavity, the O-rings will first be blocked by the flipping seat 19 and sleeved on the detection cylinder 20 located above the flipping seat 19. During detection, the hydraulic pump works to flush hydraulic oil into the hydraulic pipe 23, and enters the pipe 30 through the communication hole in the upper part of the front end of the hydraulic pipe 23, and enters the corresponding detection hole through the pipe 30. The hydraulic oil pushes the detection ejector rods 21 to move towards both ends. As Figure 8As shown, the O-ring sleeved on the outer circle of the detection cylinder 20 is pushed to expand, so as to detect the effect of the O-ring expansion, whether it can achieve the normal O-ring expansion effect, so as to judge whether the corresponding O-ring is damaged. After the detection is completed, the hydraulic oil is controlled to flow reversely to reset, and the detection ejector rod 21 is controlled to reset to release the support for the O-ring. At this time, by controlling the rotation of the flipping seat 19, the detected O-ring is flipped downward, and the O-ring falls to the next process by gravity, realizing the purpose of detecting each O-ring passing through the O-ring guiding cylinder 9.

[0029] Preferably, as Figure 7 shown, a return spring is installed between the two detection ejector rods 21 corresponding to each detection cylinder 20. The outer circle of the top of the detection cylinder 20 is chamfered. The detection cylinder 20 is convenient for assisting in controlling the reset of the two detection ejector rods 21 to release the locking of the O-ring. The chamfer design is convenient for each O-ring to be sleeved on the outer circle of the corresponding detection cylinder 20, facilitating accurate detection.

[0030] In addition, a detection annular groove is formed in the inner wall of the O-ring guiding cylinder 9. The detection annular groove is located at the outer circle of the detection cylinder 20 above the flipping seat 19. A proximity switch 22 corresponding to each detection ejector rod 21 is installed on the inner wall of the detection annular groove. The detection annular groove can provide a movement space for the outer expansion detection of the O-ring. When the two detection ejector rods 21 extend to push the O-ring for outer expansion detection, the O-ring contacts the proximity switch 22, and the proximity switch 22 can detect whether the O-ring has expanded to the specified position, facilitating the improvement of the detection accuracy.

[0031] It is worth mentioning that please refer to Figures 6-8, an O-ring positioning groove 18 is provided with a driving member 24. The output end of the driving member 24 is rotationally connected to the flipping seat 19 through a gear ring. A solenoid valve 25 is installed in the hydraulic pipe 23, and a pressure sensor 26 is embedded at the end of the hydraulic pipe 23. An assembly intelligent controller 5 is also provided on the workbench 1. The assembly intelligent controller 5 is provided with a defective product detection module, a processing module and a reminder module. The defective product detection module is respectively signal-connected to the analysis module, the proximity switch 22, the solenoid valve 25, the pressure sensor 26 and the hydraulic pump. The processing module is respectively signal-connected to the reminder module and the driving member 24. The reminder module is signal-connected to the warning lamp 7. The warning lamp 7 is installed on the outer shell of the assembly intelligent controller 5. After the O-ring expands, it will generate a certain reaction force on the detection push rod 21 and push the detection push rod 21 in the reverse direction to extrude the hydraulic oil in the detection hole. When the O-ring is damaged, the reaction force generated by its expansion on the detection push rod 21 decreases, so that the pressure data detected by the pressure sensor 26 will also be lower than the pressure data when the O-ring is not damaged. When detecting the defect of each O-ring entering the O-ring guide cylinder 9, the O-ring is sleeved on the detection cylinder 20. At this time, the defective product detection module controls the hydraulic pump to work to increase the pressure of the hydraulic pipe 23 and controls the solenoid valve 25 to open. The hydraulic oil enters the detection hole and pushes the two detection push rods 21 to extend to push the O-ring to expand outward. When the O-ring expands outward and contacts the proximity switch 22, the proximity switch 22 sends the detected position signal to the defective product detection module. The defective product detection module judges that the O-ring has expanded to the specified position. At this time, the defective product detection module will control the solenoid valve 25 to close and the hydraulic pump to stop working, so that the hydraulic pressure of the hydraulic oil in the section of the solenoid valve 25 close to the pipeline 30 in the hydraulic pipe 23 remains constant. At this time, the pressure sensor 26 feeds back the detected pressure data of the hydraulic pipe 23 to the defective product detection module. At the same time, the defective product detection module controls the solenoid valve 25 to open to relieve the pressure of the hydraulic pipe 23 and reset. At this time, the detection push rod 21 and the O-ring are reset; the defective product detection module sends the pressure data to the processing module. The processing module compares the pressure data detected by the pressure sensor 26 with the normal pressure data (the normal pressure data corresponding to the qualified O-ring is preset in the processing module). When it is judged that the pressure data is the same as the normal pressure data, the processing module judges that the corresponding O-ring is qualified. The processing module controls the driving member 24 to work to drive the flipping seat 19 to flip, and the corresponding O-ring is flipped downward and falls along the O-ring guide cylinder 9; when it is judged that the pressure data is less than the normal pressure data, the processing module judges that the corresponding O-ring is unqualified. The processing module sends an unqualified reminder signal to the reminder module. The reminder module controls the warning lamp 7 to work and emits an unqualified reminder light for the staff to handle. And the processing module controls the driving member 24 to work to drive the flipping seat 19 to flip, and the corresponding O-ring is flipped downward and discharged for the staff to handle.

[0032] In this embodiment, please refer to Figures 6-8, a reject discharging mechanism is further provided on the O-ring positioning groove 18. The reject discharging mechanism includes a reject guiding plate 27 horizontally inserted into the O-ring guiding cylinder 9, and a telescopic member 29 installed on the O-ring positioning groove 18. The output end of the telescopic member 29 is installed with the reject guiding plate 27. The reject guiding plate 27 is arranged below the flipping seat 19. The processing module is signal-connected to the telescopic member 29. When the processing module determines that the corresponding O-ring is unqualified, the processing module sends a reminder signal of unqualified to the reminder module. The reminder module controls the warning light 7 to work and emits a reminder light of unqualified. At the same time, the processing module controls the telescopic member 29 to work. The telescopic member 29 drives the reject guiding plate 27 to be inserted into the O-ring guiding cylinder 9. When the processing module controls the driving member 24 to work to drive the flipping seat 19 to flip and discharge the corresponding O-ring downward, the corresponding O-ring will be intercepted by the reject guiding plate 27 and discharged to the waste collection place along the reject guiding plate 27, realizing the functions of automatic detection and automatic screening of rejects, reducing the labor intensity of personnel. One end of the reject guiding plate 27 close to the O-ring guiding cylinder 9 is inclined, and a reject discharging groove 28 is opened at one end of the reject guiding plate 27 away from the O-ring guiding cylinder 9. The O-ring falls onto the reject guiding plate 27 and falls into the reject discharging groove 28 along the inclined reject guiding plate 27 and is discharged from the reject discharging groove 28, realizing the functions of automatic detection and automatic screening of rejects.
