Description

Technical Field

[0001] This application relates to the technical field of dual - flow channel volute assembly, and in particular to an integrated device and working method for dual - flow channel volute detection and assembly. Background Art

[0002] A dual - flow channel volute is a volute design with two independent flow channels, which is widely used in fields such as turbochargers and water pumps. Its internal structure usually divides the volute flow channel into two relatively independent flow channels by a partition wall, enabling the fluid to flow separately in the two flow channels, thereby effectively utilizing the pulse energy of the fluid and improving the efficiency and performance of the device.

[0003] Currently, there is a design of a dual - flow channel volute including a first pipe and a second pipe. The second pipe is installed on the side wall of the first pipe and is in communication with the first pipe. In addition, a rotary pin hole is provided on the side wall of the first pipe. A bar code or a two - dimensional code is provided on the outer surface of the dual - flow channel volute.

[0004] Bushings usually play a role in protecting, damping, and reducing wear in mechanical components. In a dual - flow channel pump, the bushing is installed at the rotary pin hole of the dual - flow channel volute to improve the durability and reliability of the device.

[0005] During the process of assembling the bushing to the dual - flow channel volute, it generally includes three workstations: appearance inspection, airtightness inspection, and assembling the bushing to the dual - flow channel volute. Currently, each workstation is equipped with a staff member. However, when assembling a large number of dual - flow channel volutes, it is easy for the staff to make mistakes during the operation, which will affect the assembly quality of the dual - flow channel volute. At the same time, the operation by multiple staff members also increases the cost of assembling the dual - flow channel volute. Summary of the Invention

[0036] 1. First, the bushing and the double-flow channel volute are placed near the robotic arm through the loading and unloading device. The volute pickup part of the robotic arm sends the double-flow channel volute to the first barcode scanning unit of the volute airtightness detection device for barcode scanning and recording, and then enters the airtightness detection link. The double-flow channel volute with qualified airtightness is sent to the bushing assembly device, and at the same time, the bushing is accurately sent to the bushing assembly device through the vibrating disk and the pushing part of the bushing loading component. During this process, the bushing will pass through the bushing lubrication component for surface lubrication to ensure smooth assembly. The bushing assembly device accurately assembles the bushing into the rotary pin hole of the double-flow channel volute. After assembly, the double-flow channel volute with the assembled bushing moves to the go / no-go gauge detection unit, and the bushing is detected through the go / no-go gauge floating seat containing a pressure sensor to judge whether the assembly quality is qualified. Finally, according to the detection results, the loading and unloading device separates and unloads the double-flow channel volutes with qualified assembly and unqualified assembly.

Subsequently, the operator places the visually inspected double-flow channel volute on the volute loading component, and it is sent to near the robotic arm through the conveying device. The robotic arm sends it into the volute airtightness detection device for detection. The qualified products are temporarily stored on the buffer table, and the unqualified products are discharged through the first volute unloading component. At the same time, the robotic arm picks up the bushing from the bushing loading component, lubricates it with the lubricating oil of the bushing lubrication component, and then sends it to the bushing assembly device. The robotic arm assembles the double-flow channel volute on the buffer table with the bushing. While the assembly is completed, the next double-flow channel volute has entered the airtightness detection link, realizing process connection. After assembly, the robotic arm sends the volute to the go / no-go gauge detection unit, and the assembly quality of the bushing is detected through the go / no-go gauge floating seat containing a pressure sensor.

[0045] The following will Figures 1 - 5 further describe the present application in detail with reference to the attached

[0046] The embodiment of the present application discloses an integrated device and working method for double-channel volute detection and assembly.

[0047] An integrated device for double-channel volute detection and assembly is used to install the bushing 6 at the rotary pin hole of the double-channel volute 5, and includes a robotic arm 1, a volute airtightness detection device 2, a loading and unloading device 3, a bushing assembly device 4, and a control system. Among them, the volute airtightness detection device 2, the loading and unloading device 3, and the bushing assembly device 4 are circumferentially distributed along the rotation axis of the robotic arm 1.

[0048] The end of the robotic arm 1 is provided with a volute picking part and a bushing 6 picking part. The volute airtightness detection device 2 is provided with a first code scanning unit 21, and the bushing assembly device 4 is provided with a second code scanning unit 41. A bar code or two-dimensional code is provided on the outer surface of the double-channel volute 5 for easy code scanning.

[0049] When the bushing 6 needs to be assembled into the double-flow channel volute 5, the bushing 6 and the double-flow channel volute 5 are placed near the robotic arm 1 through the loading and unloading device 3. The double-flow channel volute 5 is placed at the first code scanning unit 21 by the volute picking part on the robotic arm 1 for code scanning to record the product information. Subsequently, the double-flow channel volute 5 is placed in the volute airtightness detection device 2 for airtightness detection.

[0050] The bushing 6 is placed in the bushing assembly device 4 through the bushing picking part, and the double-flow channel volute 5 with qualified airtightness is also placed in the bushing assembly device 4 through the volute picking part. The bushing 6 is assembled into the double-flow channel volute 5 through the bushing assembly device 4. After that, according to the assembly quality of the double-flow channel volute 5, the qualified and unqualified double-flow channel volutes 5 are separated and discharged through the loading and unloading device 3, so as to facilitate the subsequent classification and collection of the double-flow channel volutes 5. The unqualified double-flow channel volutes 5 are traced according to the code scanning results to improve the quality of the double-flow channel volutes 5.

[0051] A go / no-go gauge detection unit 43 is provided near the bushing assembly device 4, and the go / no-go gauge detection unit 43 is in plug-in fit with the bushing 6. In the embodiment of the present application, the go / no-go gauge detection unit 43 is a go / no-go gauge floating seat containing a pressure sensor. When performing a go / no-go gauge detection on the bushing 6 on the assembled double-flow channel volute 5, the double-flow channel volute 5 with the assembled bushing 6 is moved to a position near the go / no-go gauge detection unit 43. Subsequently, the go / no-go gauge floating seat is inserted into the bushing 6. During the process of inserting the go / no-go gauge floating seat into the bushing 6 on the double-flow channel volute 5, the frictional force between the go / no-go gauge floating seat and the inner wall of the bushing 6 will change the signal value on the pressure sensor. It is judged whether the bushing 6 assembled on the double-flow channel volute 5 is qualified according to whether the signal value on the pressure sensor is within the set value range.

[0052] Several double-flow channel volutes 5 with different airtightness defects are provided near the volute airtightness detection device 2, and several double-flow channel volutes 5 assembled with bushings 6 with different assembly defects are provided near the bushing assembly device 4. Before the volute airtightness detection device 2 performs an airtightness detection on the double-flow channel volute 5 to be assembled, the volute airtightness detection device 2 is first used to detect the double-flow channel volutes 5 with different airtightness defects, so as to perform a pre-detection on the volute airtightness detection device 2, thereby judging whether the volute airtightness detection device 2 is working properly.

[0053] Before the go / no-go gauge detection unit 43 officially detects the bushing 6 assembled on the double-flow channel volute 5, the go / no-go gauge detection unit 43 is first used to detect the double-flow channel volutes 5 assembled with bushings 6 with different assembly defects, and it is judged whether the go / no-go gauge detection unit 43 is working properly according to the detection results of the go / no-go gauge detection unit 43. In the embodiment of the present application, the volute airtightness detection device 2 is an airtightness detector, and the bushing assembly device 4 is a bushing pressing machine.

[0054] The loading and unloading device 3 includes a bushing loading assembly 31, a volute casing loading assembly 32, a volute casing first unloading assembly 33, and a volute casing second unloading assembly 34. A bushing lubrication assembly 42 is provided near the bushing loading assembly 31, and a buffer table 36 is provided near the bushing lubrication assembly 42. An upper loading turnover box 321 is provided near the volute casing loading assembly 32, and a lower loading turnover box 341 is provided near the volute casing first unloading assembly 33 and the volute casing second unloading assembly 34.

[0055] The bushing loading assembly 31 includes a workbench 311, a loading trough 312, a vibrating bowl 313, and a pushing part 314. The loading trough 312 is installed on the workbench 311, the vibrating bowl 313 is located below the loading trough 312, and one end of the loading trough 312 close to the vibrating bowl 313 is inclined downward.

[0056] The pushing part 314 is installed at the output end of the vibrating bowl 313 and is used to control the position of the bushing 6. The pushing part 314 includes a pushing trough, a lateral pushing member, and a longitudinal pushing member. The pushing trough is fixed at a position near the output end of the vibrating bowl 313, the opening of the pushing trough faces upward, the bushing 6 is vertically placed inside the pushing trough, and is in sliding fit with the pushing trough.

[0057] The lateral pushing member is a lateral pushing cylinder, which is installed at the end of the pushing trough. The end of the push rod of the lateral pushing cylinder contacts the bushing 6, and the position of the bushing 6 is changed by changing the position of the lateral pushing cylinder. An opening is provided on the side wall of the pushing trough for the bushing 6 on the vibrating bowl 313 to enter the inside of the pushing trough. The longitudinal pushing member is a longitudinal pushing cylinder, which is vertically arranged, and the push rod of the longitudinal pushing cylinder penetrates through the pushing trough, and the top of the longitudinal pushing cylinder contacts the bottom of the bushing 6.

[0058] The worker is located near the workbench 311 and pours the bushings 6 into the loading trough 312 in batches. The bushings 6 slide into the vibrating bowl 313 under the action of gravity. Subsequently, under the vibration of the vibrating bowl 313, the bushings 6 enter the inside of the pushing trough from the opening of the pushing trough. Subsequently, the bushing 6 is pushed above the longitudinal pushing cylinder by the lateral pushing cylinder, and then the bushing 6 is pushed out to a predetermined height by the longitudinal pushing cylinder.

[0059] The volute casing loading assembly 32 includes a chain plate and a placement seat. The chain plate is driven by a motor, the mounting seat is fixedly installed on the chain plate, a placement groove is provided on the mounting seat, and the double-flow volute casing 5 is placed in the placement groove. When transporting the double-flow volute casing 5, the worker located on the workbench 311 places the double-flow volute casing 5 from the upper loading turnover box 321 into the placement groove of the placement seat, and precisely controls the position of the double-flow volute casing 5 through the chain plate.

[0060] The second blanking component 34 of the volute is installed above the first blanking component 33 of the volute. The first blanking component 33, the second blanking component 34, and the third blanking component 35 of the volute are similar in structure, and all are equipped with conveyor belts. The first blanking component 33 and the third blanking component 35 of the volute are respectively located on both sides of the workbench 311. When transporting the double-flow volute 5, the double-flow volute 5 is placed on the conveyor belt, and the unqualified double-flow volutes 5 are transported towards the direction close to the blanking turnover box 341 through the conveyor belt.

[0061] When the conveyor belt transports the double-flow volute 5 to a position close to the blanking turnover box 341, the staff takes the double-flow volute 5 on the conveyor belt and places it into the blanking turnover box 341 for subsequent transportation. By the staff placing the double-flow volute 5 into the lower turnover box, the possibility of the double-flow volute 5 being further damaged due to directly falling from a height into the blanking turnover box 341 is reduced.

[0062] At the same time, when the staff places the double-flow volute 5, they can adjust its position in the blanking turnover box 341, so as to facilitate the regular placement of the double-flow volutes 5 in the blanking turnover box 341, load as many double-flow volutes 5 as possible, and improve the space utilization rate of the blanking turnover box 341.

[0063] One end of the conveyor belt close to the blanking turnover box 341 is provided with a baffle, and the double-flow volute 5 on the conveyor belt is blocked by the baffle, so as to reduce the possibility of the double-flow volute 5 directly falling from the conveyor belt into the blanking turnover box 341, thereby alleviating the work pressure of the staff.

The fixture control unit controls the volute pickup part and the bushing 6 pickup part to perform grasping or placing actions.

[0067] The conveying module includes a bushing conveying control unit, a volute feeding conveying control unit, and a volute discharging conveying control unit. The bushing conveying control unit controls the operation of the vibrating bowl 313, the lateral pushing cylinder, and the longitudinal pushing cylinder.

The handling robot is used to complete the full process of workpiece grasping, code scanning, airtightness detection, workpiece removal, code scanning, bushing feeding, bushing pressing, go / no-go gauge inspection, and discharging to the conveying line. The number of production operators is reduced from 3 to 1. The staff only needs to work at the workbench 311, reducing the employment by 60%. The comprehensive cost reduction and efficiency improvement are increased by 20%. The production stability of the product is further improved, and the qualified rate is increased to 99.9%.

[0071] The implementation principle of an integrated device for detecting and assembling a double-flow channel volute in an embodiment of this application is as follows: First, the bushing 6 and the double-flow channel volute 5 are placed near the robotic arm 1 through the loading and unloading device 3. The volute picking part of the robotic arm 1 sends the double-flow channel volute 5 to the first code scanning unit 21 of the volute airtightness detection device 2 for code scanning and recording, and then enters the airtightness detection link. The double-flow channel volute 5 with qualified airtightness is sent to the bushing assembly device 4. At the same time, the bushing 6 is accurately sent to the bushing assembly device 4 through the vibrating disk 313 and the pushing part 314 of the bushing loading assembly 31. During this process, the bushing 6 will pass through the bushing lubrication assembly 42 for surface lubrication to ensure smooth assembly. The bushing assembly device 4 accurately assembles the bushing 6 to the rotary pin hole of the double-flow channel volute 5. After the assembly is completed, the double-flow channel volute 5 with the assembled bushing 6 moves to the go-gauge detection unit 43, and the bushing 6 is detected through the go-gauge floating seat containing a pressure sensor to judge whether the assembly quality is qualified. Finally, according to the detection results, the loading and unloading device 3 separates and unloads the double-flow channel volute 5 with qualified assembly from the unqualified double-flow channel volute 5. The qualified products enter the subsequent processes, and the unqualified products are processed according to code scanning traceability to improve product quality. The whole process realizes automatic detection and assembly, improves production efficiency and assembly accuracy, and ensures the reliability of the equipment through pre-detection and go-gauge detection.

[0072] This application also provides a working method for an integrated device for detecting and assembling a double-flow channel volute. The method is applied to the above-mentioned integrated device for detecting and assembling a double-flow channel volute. The method includes:

[0073] S1. Equipment self-check: Place several double-flow channel volutes 5 with different airtightness defects in the volute airtightness detection device 2 for airtightness defect detection, and at the same time place several double-flow channel volutes 5 assembled with bushings 6 with different assembly defects at the go-gauge detection unit 43 for assembly defect detection, so as to verify whether the detection function of the equipment is normal and ensure the reliability of the subsequent production process.

[0074] S2. Raw material feeding: After the double-flow channel volute 5 is visually inspected by the staff, the staff places the double-flow channel volute 5 on the volute loading assembly 32. The volute loading assembly 32 transports the double-flow channel volute 5 to a position near the robotic arm 1 through the chain plate conveying mechanism to prepare for the subsequent airtightness detection.

[0075] S3. Volute airtightness detection: The robotic arm 1 picks up the double-flow channel volute 5 from the volute loading assembly 32 and places it in the volute airtightness detection device 2 for airtightness detection. The double-flow channel volute 5 with qualified detection is placed on the buffer table 36 and waits for the subsequent bushing 6 assembly process; the double-flow channel volute 5 with unqualified detection is placed in the volute first unloading assembly 33 and discharged for subsequent analysis and processing.

[0076] S4. Bushing 6 Oil Immersion and Loading: The robotic arm 1 picks up the bushing 6 from the bushing loading assembly 31 and then places the bushing 6 in the lubricating oil of the porous elastic oil-absorbing material in the bushing lubricating assembly 42 for surface lubrication to reduce the friction between the bushing 6 and the double-flow channel volute 5 and ensure smooth assembly. The lubricated bushing 6 is then placed in the bushing assembly device 4 and waits for assembly.

[0077] S5. Bushing 6 Assembly: The robotic arm 1 places the double-flow channel volute 5 on the buffer table 36 into the bushing assembly device 4, and the bushing assembly device 4 precisely assembles the bushing 6 into the double-flow channel volute 5. While the bushing 6 is being assembled into the double-flow channel volute 5, the robotic arm 1 picks up the next double-flow channel volute 5 from the volute loading assembly 32 and places it in the volute airtightness detection device 2 for detection, achieving an efficient connection between the detection and assembly processes and improving production efficiency.

[0078] S6. Assembly Detection: The robotic arm 1 places the double-flow channel volute 5 assembled with the bushing 6 at the go / no-go gauge detection unit 43 for detection. The go / no-go gauge detection unit 43 inserts a go / no-go gauge floating seat containing a pressure sensor into the bushing 6 and determines whether the assembly of the bushing 6 is qualified according to the signal value of the pressure sensor. The double-flow channel volutes 5 with qualified assembly are placed in the volute first unloading assembly 33 and wait for subsequent processes; the double-flow channel volutes 5 with unqualified assembly are placed on the volute second unloading assembly 34 for subsequent analysis and processing.

[0079] S7. Circular Operation: The robotic arm 1 returns to execute step S2 and continues the loading operation of the double-flow channel volute 5 to realize the circular operation of the entire production process and ensure the continuous production of the equipment.

[0080] S8. Final Unloading: The staff conducts an appearance inspection on the assembled double-flow channel volute 5 taken out from the volute third unloading assembly 35. After confirming that it is correct, it is placed in the unloading turnover box 341 to complete the entire production process.

[0081] During the entire working process, before the double-flow channel volute 5 is placed in the volute airtightness detection device 2, it will pass through the first barcode scanning unit 21 for barcode scanning and recording to facilitate product information tracing; before the double-flow channel volute 5 is placed in the bushing assembly device 4, it will pass through the second barcode scanning unit 41 for barcode scanning and recording to ensure the traceability of the assembly process and quality control.

[0082] Due to the cyclic operation of the robotic arm 1, the workflow of the robotic arm during cyclic operation is as follows: The process of pressing the bushing 6 inside the bushing assembly device 4 takes about 76 seconds. While the bushing is being pressed, in accordance with the working sequence of the robotic arm 1, it takes about 10 seconds to remove the volute from the volute airtightness detection device 2 and place it on the buffer table 36 or the blanking conveyor belt. The process of scanning the volute and placing it into the volute airtightness detection device 2 takes about 16 seconds. It is detected in the volute airtightness detection device 2 for about 50 seconds. During the process of airtightness detection of the volute, it takes about 5 seconds for the robotic arm 1 to grasp the bushing 6. Then, the robotic arm 1 is idle for 45 seconds. After the airtightness detection of the volute is completed, after the bushing pressing is completed, the robotic arm 1 discharges the volute assembled with the bushing 6. This process takes about 17 seconds. Then, it grasps the volute and the bushing 6 from the buffer table 36, immerses the bushing 6 in oil, and then continues the cyclic operation. The entire cyclic operation takes about 112 seconds.

[0083] The implementation principle of the working method of the integrated device for detecting and assembling a dual-channel volute in an embodiment of the present application is as follows: The working process of the integrated device for detecting and assembling a dual-channel volute 5 mainly includes links such as equipment self-check, raw material feeding, volute airtightness detection, bushing 6 oil immersion feeding, bushing 6 assembly, assembly detection, cyclic operation, and final blanking. First, the equipment completes self-check by detecting volutes and bushings 6 with different airtightness and assembly defects to ensure the normal detection function. Subsequently, the staff places the visually inspected dual-channel volute 5 on the volute feeding component 32, and it is sent to the vicinity of the robotic arm 1 through the conveying device. The robotic arm 1 sends it into the volute airtightness detection device 2 for detection. The qualified products are temporarily stored on the buffer table 36, and the unqualified products are discharged through the first volute blanking component 33. At the same time, the robotic arm 1 picks up the bushing 6 from the bushing feeding component 31, lubricates it with the lubricating oil of the bushing lubricating component 42, and sends it to the bushing assembly device 4. The robotic arm 1 assembles the dual-channel volute 5 on the buffer table 36 with the bushing 6. While the assembly is completed, the next dual-channel volute 5 has entered the airtightness detection link, realizing the connection of processes. After the assembly is completed, the robotic arm 1 sends the volute to the go-gauge detection unit 43, and detects the assembly quality of the bushing 6 through the go-gauge floating seat containing a pressure sensor. The qualified products enter the third volute blanking component 35, and the unqualified products enter the second volute blanking component 34. Subsequently, the robotic arm 1 returns to continue the feeding operation, realizing cyclic operation. Finally, after the staff performs an appearance inspection on the assembled qualified dual-channel volute 5, they place it in the blanking turnover box 341 to complete the entire production process. During the whole process, the dual-channel volute 5 is scanned and recorded by the first scanning unit 21 and the second scanning unit 41 respectively before airtightness detection and bushing 6 assembly to ensure the traceability and quality control of the production process.

[0084] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
