Abstract

This application provides an automatic matching device, including a positioning mechanism, a pressing mechanism, and a control mechanism. The positioning mechanism is used to adapt to and position the assembly workpiece. The pressing mechanism is positioned above the assembly workpiece so that after the positioning mechanism positions the assembly workpiece, the pressing mechanism presses it down, ensuring that the height of the shim is no higher than the bottom height of the groove. The control mechanism then photographs and analyzes the groove to select a suitable size accessory for assembly, facilitating the fitting of the accessory into the groove. After the centering plate positions the assembly workpiece, the second drive assembly drives the pressing assembly to press the assembly workpiece to a designated position. The camera then photographs the assembly workpiece and transmits the data to the controller. The controller automatically analyzes the data to select the appropriate accessory to match the assembly workpiece. The entire process is simple to operate, streamlined, significantly saves time, and improves assembly efficiency.

Technical Field

[0001] This application relates to the field of assembly machine and equipment manufacturing technology, and more specifically, to an automatic selection device. Background Technology

[0002] The transfer case is a gear transmission system. Its input shaft is directly or via a universal joint to the second shaft of the transmission. It has several output shafts, each connected to a drive axle via a universal joint. The assembly process for the transfer case is as follows: First, assemble the bearing housings, bearings, gaskets, sealing rings, shaft end caps, and housing / cover. Then, install the shafts and transmission into the housing. Next, close the housing and cover, assembling them with standard fasteners. Finally, use standard fasteners to assemble the shaft end flanges and some external plugs and pipes.

[0003] However, in the relevant technologies, the existing solutions require counterweights to apply pressure and coordinate with coordinate measuring machines to select shims after measuring the height difference. The whole process is complicated, has large errors, and is difficult to operate. Summary of the Invention

[0004] The purpose of this application is to provide an automatic fitting device. It is simple to operate, simplifies processes, significantly saves time, and improves assembly efficiency.

[0005] In a first aspect, embodiments of this application provide an automatic selection and fitting device, comprising: a positioning mechanism including a first driving component and a centering plate, the first driving component being connected to the centering plate to drive the centering plate to move along a first direction, the centering plate being configured with a centering cavity along the first direction, the centering cavity being configured to accommodate an assembly workpiece for positioning the assembly workpiece; a pressing mechanism including a second driving component and a pressing component, the second driving component being connected to the pressing component to drive the pressing component to move along the first direction, such that the pressing component presses down on the assembly workpiece; and a control mechanism including a controller and an imaging component, the controller being connected to the first driving component, the second driving component, and the imaging component, the imaging component being disposed on the centering plate for photographing the assembly workpiece and transmitting the data to the controller.

[0006] In the above implementation process, the center plate is connected to the first drive component, and the pressing component is connected to the second drive component. After the center plate is used to position the assembled workpiece, the second drive component drives the pressing component to press the assembled workpiece down to the designated position. Then, the camera takes a picture of the assembled workpiece and transmits the data to the controller. The controller automatically analyzes the data to select the appropriate accessories to be assembled that match the assembled workpiece. The whole process is simple to operate, the procedures are simplified, and time is saved and assembly efficiency is improved.

[0007] In some embodiments, the centering plate includes a centering body, a centering groove, a receiving groove, and a positioning groove. The centering groove extends through the centering body along a first direction. In the first direction, the centerline of the centering groove coincides with the centerline of the centering body. The receiving groove extends along the outer edge close to the centering body, and the opening of the receiving groove faces the centering groove. The positioning groove extends from the centering groove to the outer edge of the centering body, so as to divide both the centering groove and the receiving groove into a head end and a tail end.

[0008] In the above process, the centering body is equipped with a centering groove, a receiving groove, and a positioning groove. Through the cooperation of the centering groove, the receiving groove, and the positioning groove, the assembly workpiece can be relatively fixed when it is placed on the centering body, thus achieving the positioning of the assembly workpiece. At the same time, it is beneficial for the pressing component to pressurize the assembly workpiece, the control mechanism to measure and assemble the assembly workpiece, and improves the assembly efficiency.

[0009] In some embodiments, the first driving component includes a first driving member, a connector, a slider, and a guide rail. The first driving member is connected to the connector and the slider. The connector is connected to the slider and is adapted to the guide rail. The slider is connected to the guide rail and the centering plate. The guide rail is configured to be distributed along the first direction.

[0010] In the above implementation process, the connector is connected to the output end of the first driving component, and the connector is adapted to the guide rail. The slider is connected to the guide rail, so that when the first driving component is driven, it can drive the connector to move along the distribution direction of the guide rail, thereby driving the slider to move, and finally realizing the positioning of the center plate on the assembled workpiece. This is beneficial for the pressure of the pressing component on the assembled workpiece, the measurement of the assembled workpiece by the control mechanism, and the assembly, thus improving the assembly efficiency.

[0011] In some embodiments, the positioning mechanism further includes a positioning rod connected to the centering plate. The positioning rod is configured to be distributed along the first direction and located on the side of the centering plate opposite to the pressing assembly. This facilitates the positioning of the centering plate after it is adapted to the assembled workpiece, and also facilitates the pressing assembly's application of pressure to the assembled workpiece, the control mechanism's measurement of the assembled workpiece, and the assembly itself, thereby improving assembly efficiency.

[0012] In some embodiments, the pressing assembly includes a pressing block and a pressure sensor, the pressing block being connected to the pressure sensor, and the side of the pressing block opposite to the pressure sensor being configured to press down the assembled workpiece, and the side of the pressure sensor opposite to the pressing block being connected to the second drive assembly.

[0013] In the above implementation process, the pressure block is connected to a pressure sensor, and the pressure sensor is connected to a second drive component. After the second drive component is driven, it drives the pressure block and the pressure sensor to move together along the first direction. This not only enables the downward pressure on the assembled workpiece, but also measures the downward pressure during the pressing process and transmits the pressure data to the controller to achieve intelligent control and avoid damage to the assembled workpiece.

[0014] In some embodiments, the pressure block is configured with a receiving cavity for accommodating a portion of the assembled workpiece structure during pressing, and the receiving cavity is also configured with an observation port. By accommodating a portion of the assembled workpiece structure within the receiving cavity, and by configuring the pressure block with an observation port, it is beneficial for the operator to observe the actual situation during the pressing process of the pressure block on the assembled workpiece, so as to correctly perform the selection and assembly process of the assembled workpiece.

[0015] In some embodiments, the pressing assembly further includes a pressure plate located between the pressure block and the pressure sensor, the pressure sensor passing through the pressure plate and connected to the pressure block, and the cross-sectional dimension of the pressure plate being larger than that of the pressure block.

[0016] In some embodiments, the pressing assembly further includes a pressure switch connected to the centering plate, the pressure switch being located on the side of the centering plate near the pressure plate, and the pressure switch being spaced apart from the pressure plate.

[0017] In the above implementation process, the pressure switch is connected to the centering plate and is located on one side of the pressure plate. When the second drive component presses down and the pressure plate contacts the pressure switch, even if the pressure sensor does not collect sufficient pressure, it is necessary to stop pressurizing and sound an alarm to prevent overpressure from causing structural damage.

[0018] In some embodiments, the second drive assembly includes a fixing structure and a second drive member, the fixing structure being connected to the second drive member and the second drive member being connected to the pressure sensor.

[0019] In some embodiments, the control mechanism further includes an adjustment component connected to the camera element for adjusting the position of the camera element.

[0020] In some embodiments, the automatic selection device further includes a worktable, which is connected to the first drive component and the second drive component respectively.

[0021] In the above implementation process, both the first drive component and the second drive component are configured on the worktable, which is conducive to the selection and matching of the assembled workpiece, convenient operation, simplified process, greatly saves time and improves assembly efficiency.

[0047] Example

[0048] In this application, an automatic fitting device is used to select appropriate accessories 600 to be assembled from an assembly workpiece 500. The assembly workpiece 500 includes, but is not limited to, an actuator. The accessories 600 to be assembled include, but are not limited to, snap rings. The assembly workpiece 500 includes a gasket 501, a connecting shaft 502, a pressure plate 503, a push plate 504, and a spring 505. Both the pressure plate 503 and the push plate 504 are sleeved on the connecting shaft 502. The pressure plate 503 is located above the push plate 504, and the outer edge of the pressure plate 503 extends to form a limiting boss 506. Both the disc 503 and the push disc 504 have several mounting slots on their sides closest to each other. The mounting slots are configured to accommodate part of the structure of the spring 505. The washer 501 is sleeved on the connecting shaft 502, and the washer 501 is located on the side of the pressure disc 503 away from the push disc 504. The outer edge of the connecting shaft 502 is recessed along its center with a groove 507. When the spring 505 is in the normal state, the height of the washer 501 is higher than the bottom height of the groove 507. The groove 507 is used to fit the accessory 600 to be installed.

[0049] like Figures 1-15 As shown, in a first aspect, this application provides an automatic fitting device, including: a positioning mechanism 100, a pressing mechanism 200, and a control mechanism 300. The positioning mechanism 100 is used to adapt to the assembly workpiece 500 and position the assembly workpiece 500. The pressing mechanism 200 is disposed above the assembly workpiece 500, so that after the positioning mechanism 100 positions the assembly workpiece 500, the pressing mechanism 200 presses down on the assembly workpiece 500, so that the height of the gasket 501 is not higher than the bottom height of the groove 507. The control mechanism 300 photographs and analyzes the groove 507 to select the appropriate size of the accessory 600 to be assembled, so that the accessory 600 to be assembled can be fitted into the groove 507.

[0050] Specifically, the positioning mechanism 100 includes a first driving component 101 and a centering plate 102. The first driving component 101 is connected to the centering plate 102 to drive the centering plate 102 to move along a first direction. The centering plate 102 is configured with a centering cavity along the first direction, and the centering cavity is configured to accommodate the assembled workpiece 500 for positioning the assembled workpiece 500. The pressing mechanism 200 includes a second driving component 201 and a pressing component 202. The second driving component 201 is connected to the pressing component 202 to drive the pressing component 202 to move along the first direction, so that the pressing component 202 presses down on the assembled workpiece 500. The control mechanism 300 includes a controller 301 and an imaging component 302. The controller is connected to the first driving component 101, the second driving component 201, and the imaging component 302. The imaging component 302 is disposed on the centering plate 102 for photographing the assembled workpiece 500 and transmitting the data to the controller 301.

[0051] For example, the centering plate 102 is fixedly connected to the first driving assembly 101, wherein the centering cavity of the centering plate 102 is used to adapt the pad 501 and pressure plate 503 of the assembled workpiece 500, thereby realizing the positioning in the horizontal direction (i.e., the front-back direction and the left-right direction) and the vertical direction (i.e., the up-down direction), ensuring that when the pressing mechanism 200 presses down on the assembled workpiece 500, there will be no shaking or deviation, wherein the first direction includes but is not limited to the up-down direction.

[0052] When the assembled workpiece 500 is fitted to the centering plate 102, the pressing component 202 is positioned above the assembled workpiece 500. As the pressing component 202 moves via the second driving component 201, it contacts the pad 501 of the assembled workpiece 500 and continuously presses down on the pad 501 until the bottom height of the groove 507 of the connecting shaft 502 is not lower than the height of the pad 501. Then, the second driving component 201 stops driving. The pressing process is complete.

[0053] It should be noted that when the control mechanism 300 selects and assembles the accessory 600, its process includes image acquisition, image processing, feature extraction, size calculation, and output results. The imaging component 302 includes, but is not limited to, a CCD camera (Charge Coupled). Device, charge-coupled element (CCD image sensor), the CCD camera is a semiconductor device that can convert optical images into digital signals. The CCD camera has many neatly arranged capacitors that can sense light and convert images into digital signals. Under the control of external circuitry, each small capacitor can transfer its charge to an adjacent capacitor; of course, other cameras with LED light sources are also possible. The imaging element 302 can be used to photograph the groove 507 of the assembled workpiece 500 after the pressing component 202 has pressed down on the assembled workpiece 500. It can also be used to photograph whether the centering plate 102 is properly adapted to the assembled workpiece 500 when the centering plate 102 moves through the first driving component 101, and feed the data back to the controller 301; of course, the imaging element 302 can also be used to photograph the pressing process of the pressing component 202 on the assembled workpiece 500, etc.

[0054] The controller 301 can calculate the size of the groove 507 based on the data captured by the camera 302, automatically output the required shim 501 and the total thickness of the workpiece to be assembled, and after completing the selection process, control the second drive component 201 to lift the pressing component 202, then put the snap ring and the shim 501 into the connecting shaft 502, control the second drive component 201 to press down the pressing component 202, the pressing component 202 contacts the workpiece to be assembled, and presses the workpiece into the groove 507, completing the adjustment and pressing.

[0055] In the above implementation process, the center plate 102 is connected to the first drive assembly 101, and the pressing assembly 202 is connected to the second drive assembly 201. After the center plate 102 is used to position the assembly workpiece 500, the second drive assembly 201 drives the pressing assembly 202 to press the assembly workpiece 500 down to the designated position. Then, the camera 302 takes a picture of the assembly workpiece 500 and transmits the data to the controller 301. The controller 301 automatically analyzes the data to select the appropriate accessory 600 to be assembled with the assembly workpiece 500. The whole process is simple to operate, the procedures are simplified, and time is saved and assembly efficiency is improved.

[0056] In some embodiments, the centering plate 102 includes a centering body 1021, a centering groove 1022, a receiving groove 1023, and a positioning groove 1024. The centering groove 1022 penetrates the centering body 1021 along a first direction. In the first direction, the centerline of the centering groove 1022 coincides with the centerline of the centering body 1021. The receiving groove 1023 extends along the outer edge close to the centering body 1021, and the opening of the receiving groove 1023 faces the centering groove 1022. The positioning groove 1024 extends towards the outer edge of the centering body 1021 with the centering groove 1022 as the starting position, so as to divide both the centering groove 1022 and the receiving groove 1023 into a head end and a tail end.

[0057] For example, both the centering groove 1022 and the receiving groove 1023 are configured in an arc shape, and the centering groove 1022 is configured to receive the gasket 501 of the assembled workpiece 500, the receiving groove 1023 is configured to receive the pressure plate 503 of the assembled workpiece 500, and the positioning groove 1024 is configured to receive the limiting boss 506 of the pressure plate 503.

[0058] In the above implementation process, the centering body 1021 is equipped with a centering groove 1022, a receiving groove 1023 and a positioning groove 1024. Through the cooperation of the centering groove 1022, the receiving groove 1023 and the positioning groove 1024, when the assembled workpiece 500 is placed on the centering body 1021, the relatively fixed position of the assembled workpiece 500 can be ensured, and the positioning of the assembled workpiece 500 can be achieved. At the same time, it is beneficial to the pressing component 202 pressurizing the assembled workpiece 500, the control mechanism 300 measuring the assembled workpiece 500 and assembling it, thereby improving the assembly efficiency.

[0059] In some embodiments, the first driving assembly 101 includes a first driving member 1011, a connector 1012, a slider 1013, and a guide rail 1014. The first driving member 1011 is connected to the connector 1012 and the slider 1013. The connector 1012 is connected to the slider 1013 and is adapted to the guide rail 1014. The slider 1013 is connected to the guide rail 1014 and the centering plate 102. The guide rail 1014 is configured to be distributed along the first direction.

[0060] For example, the first driving member 1011 includes, but is not limited to, a motor, and can be controlled by the controller 301. The connecting member 1012 includes, but is not limited to, a gear, and is sleeved on the first driving member 1011. The connecting member 1012 is located in the inner cavity of the slider 1013. The first driving member 1011 can be fixed to the slider 1013 by bolts. The slider 1013 is snapped onto the guide rail 1014. The side of the slider 1013 away from the guide rail 1014 can be fixedly connected to the centering plate 102 by bolts. A rack is arranged on the side of the guide rail 1014 near the connecting member 1012. The rack is used to mesh with the connecting member 1012 so that the slider 1013 can move along the distribution direction of the guide rail 1014 under the drive of the first driving member 1011.

[0061] In the above implementation process, the connector 1012 is connected to the output end of the first drive member 1011, and the connector 1012 is adapted to the guide rail 1014. The slider 1013 is connected to the guide rail 1014, so that when the first drive member 1011 is driven, it can drive the connector 1012 to move along the distribution direction of the guide rail 1014, thereby driving the slider 1013 to move, and finally realize the positioning of the center plate 102 on the assembled workpiece 500. This is beneficial for the pressing component 202 to pressurize the assembled workpiece 500, the control mechanism 300 to measure the assembled workpiece 500, and the assembly, thereby improving the assembly efficiency.

[0062] In some embodiments, the positioning mechanism further includes a positioning rod 103 connected to the centering plate 102. For example, the centering plate 102 has a plurality of threaded holes on the side near the slider 1013, and the positioning rod 103 is screwed into the threaded holes. The positioning rod 103 is configured to be distributed along the first direction, and the positioning rod 103 is located on the side of the centering plate 102 opposite to the pressing assembly 202. This facilitates the positioning of the centering plate 102 after it is adapted to the assembled workpiece 500, and facilitates the pressing assembly 202's application of pressure to the assembled workpiece 500, the control mechanism 300's measurement of the assembled workpiece 500, and the assembly, thereby improving assembly efficiency.

[0063] In some embodiments, the pressing assembly 202 includes a pressing block 2021 and a pressure sensor 2022. The pressing block 2021 is connected to the pressure sensor 2022, wherein the pressure sensor 2022 is threadedly connected to the second drive assembly 201, the pressing block 2021 is threadedly connected to the pressure sensor 2022, and the side of the pressing block 2021 opposite to the pressure sensor 2022 is configured to press down the assembled workpiece 500. The side of the pressure sensor 2022 opposite to the pressing block 2021 is connected to the second drive assembly 201.

[0064] In the above implementation process, the pressure block 2021 is connected to the pressure sensor 2022, and the pressure sensor 2022 is connected to the second drive component 201. After the second drive component 201 is driven, it drives the pressure block 2021 and the pressure sensor 2022 to move together along the first direction. This not only enables the pressing of the assembled workpiece 500, but also allows the measurement of the pressing pressure during the pressing process and the transmission of the pressure data to the controller 301, thereby achieving intelligent control and preventing damage to the assembled workpiece 500.

[0065] In some embodiments, the pressure block 2021 is provided with a receiving cavity, which is configured to accommodate a portion of the structure of the assembled workpiece 500 during pressing. Specifically, the receiving cavity has an opening on the side closest to the assembled workpiece 500, which is configured for the portion of the assembled workpiece 500 to pass through. The receiving cavity is also provided with observation ports 2023, and two observation ports 2023 may be provided, distributed symmetrically on both sides of the pressure block 2021. By accommodating a portion of the structure of the assembled workpiece 500 in the receiving cavity, and by providing observation ports 2023 to the pressure block 2021, it is beneficial for the operator to observe the actual situation during the pressing process of the pressure block 2021 on the assembled workpiece 500, so as to correctly perform the selection and assembly process of the assembled workpiece 500.

[0066] In some embodiments, the pressing assembly 202 further includes a pressure plate 2024, which is located between the pressure block 2021 and the pressure sensor 2022. The pressure sensor 2022 passes through the pressure plate 2024 and is connected to the pressure block 2021, and the cross-sectional dimension of the pressure plate 2024 is larger than that of the pressure block 2021.

[0067] For example, the pressure plate 2024 includes, but is not limited to, a T-shape. The pressure sensor 2022 passes through the middle of the pressure plate 2024, and the pressure plate 2024 and the pressure block 2021 are fitted together after being connected by the thread of the pressure sensor 2022. At the same time, in order to avoid structural damage during the pressing process, the pressure plate 2024 can be configured to have three positions protruding relative to the pressure block 2021, and these three positions are equally spaced to facilitate pressure detection during the pressing process (that is, each of the three positions is equipped with a pressure switch 2025).

[0068] In some embodiments, the pressing assembly 202 further includes a pressure switch 2025, which is connected to the centering plate 102. The pressure switch 2025 is located on the side of the centering plate 102 near the pressure plate 2024, and is spaced apart from the pressure plate 2024. Exemplarily, the pressing assembly 202 also includes a column 2026, which is threaded to the centering plate 102. Three columns 2026 are configured and evenly spaced. Each column 2026 is connected to the pressure switch 2025, and all columns 2026 are distributed along the first direction. The pressure switch 2025 is located on the side of the column 2026 near the pressure plate 2024.

[0069] In the above implementation process, the pressure switch 2025 is connected to the centering plate 102 and is located on one side of the pressure plate 2024. When the second drive assembly 201 presses down to press the pressure plate 2024 and contacts the pressure switch 2025, even if the pressure sensor 2022 does not collect sufficient pressure, it is necessary to stop pressurizing and sound an alarm to prevent overpressure from causing structural damage.

[0070] In some embodiments, the second drive assembly 201 includes a fixing structure and a second drive member 2011.
