Description

Technical Field

[0001] This application relates to the field of automated processing technology, and in particular to a detection device. Background Technology

[0002] In machining, fixtures are typically used to hold workpieces in place, reducing the risk of workpiece displacement during processing and ensuring machining accuracy. However, after prolonged use, the locking mechanisms (such as brass pillars) within the fixture may wear or loosen, causing the fixture to fail to meet production requirements. Therefore, technicians need to frequently inspect the fixtures. However, traditional fixture inspection generally relies on manual methods, which are not only inefficient but also prone to significant measurement errors. Summary of the Invention

[0003] In view of this, it is necessary to provide a detection device to improve the technical problems of low efficiency and large measurement error in existing fixture detection.

[0004] One embodiment of this application provides a testing device for testing a fixture. The fixture includes a locking member configured to lock into a carrier. The testing device includes a frame and a testing mechanism, the frame having a testing station. The testing mechanism includes a pressure testing component mounted at the testing station, configured to test the weight of the locking member. And / or, the testing mechanism includes a concentricity testing component mounted at the testing station, configured to test the concentricity of the locking member. And / or, the testing mechanism includes a distance testing component mounted at the testing station, configured to test the movement distance of the locking member to determine whether the locking member meets the requirements for locking into the carrier.

[0005] In the aforementioned testing device, after the fixture is fixed at the testing station, the pressure testing component, concentricity testing component, and distance testing component can automatically detect the corresponding parameters of the locking component (i.e., the weight of the locking component, the concentricity of the locking component, and the movement distance of the locking component), and determine whether the locking component meets the requirements for locking with the carrier based on the measurement results. Compared with existing manual testing, this not only improves the testing efficiency of the fixture and saves manpower, but also reduces the error of manual measurement and improves the accuracy of fixture measurement.

[0006] In some embodiments of this application, the detection station includes a first detection position and a second detection position, which are arranged in a specific order. A pressure detection component is located at the first detection position, and a concentricity detection component and a distance detection component are located at the second detection position. The detection device also includes a positioning and transfer mechanism mounted on the frame and configured to carry a fixture and drive the fixture to move to the first or second detection position. When the fixture is in the first detection position, the pressure detection component is configured to detect the weight of the locking element; when the fixture is in the second detection position, the concentricity detection component is configured to detect the concentricity of the locking element, and the distance detection component is configured to detect the moving distance of the locking element.

[0007] In some embodiments of this application, the positioning and transfer mechanism includes a second drive assembly and a carrier. The second drive assembly is mounted on a frame and connected to the carrier. The carrier is configured as a loading fixture, and the second drive assembly is configured to drive the carrier to move to a first detection position or a second detection position.

[0008] In some embodiments of this application, the carrier has an assembly position configured to receive a fixture. The positioning and transfer mechanism further includes a laser assembly mounted on the carrier and located around the assembly position. The laser assembly is configured to irradiate the assembly position to detect whether the fixture is tilted.

[0009] In some embodiments of this application, the pressure detection assembly includes a first drive member, a pressure sensor, and a first probe. The first drive member is mounted on a frame, the pressure sensor is connected to the first drive member, and the first probe is mounted on the pressure sensor. The first drive member is configured to drive the pressure sensor to move so that the first probe abuts against a locking member and acts on the pressure sensor to obtain the weight of the locking member.

[0010] In some embodiments of this application, the first probe includes a needle body, an elastic part, and a bushing. The bushing is mounted on a pressure sensor, the needle body slides through the bushing, the elastic part is sleeved on the needle body, and one end of the elastic part abuts against the needle body, while the other end abuts against the pressure sensor.

[0011] In some embodiments of this application, the needle body is provided with a limiting part, and the bushing is provided with a limiting surface. The limiting part and the limiting surface cooperate to constrain the relative position of the needle body and the bushing.

[0012] In some embodiments of this application, the concentricity detection component includes a first visual imager and a second visual imager, both mounted on a frame and located on opposite sides of the detection station. The first visual imager is configured to acquire an image of the top surface of the fixture, and the second visual imager is configured to acquire an image of the clamping surface of the fixture, in order to determine the concentricity of the locking element.

[0013] In some embodiments of this application, the distance detection component includes a second drive member, a second probe, and a displacement sensor.

The conveying mechanism is mounted on a frame and configured to carry and transport the fixture. The conveying mechanism has a gripping station. The transporting mechanism includes a first drive assembly and a gripper assembly, the first drive assembly being connected to the gripper assembly. The first drive assembly is configured to drive the gripper assembly to move, such that the gripper assembly transports the fixture between the gripping station and the testing station.

[0017] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0019] One embodiment of this application provides a testing device for testing a fixture. The fixture includes a locking member configured to lock into a carrier. The testing device includes a frame and a testing mechanism, the frame having a testing station. The testing mechanism includes a pressure testing component mounted at the testing station, configured to test the weight of the locking member. And / or, the testing mechanism includes a concentricity testing component mounted at the testing station, configured to test the concentricity of the locking member. And / or, the testing mechanism includes a distance testing component mounted at the testing station, configured to test the movement distance of the locking member to determine whether the locking member meets the requirements for locking into the carrier.

[0020] In the aforementioned testing device, after the fixture is fixed at the testing station, the pressure testing component, concentricity testing component, and distance testing component can automatically detect the corresponding parameters of the locking component (i.e., the weight of the locking component, the concentricity of the locking component, and the movement distance of the locking component), and determine whether the locking component meets the requirements for locking with the carrier based on the measurement results. Compared with existing manual testing, this not only improves the testing efficiency of the fixture and saves manpower, but also reduces the error of manual measurement and improves the accuracy of fixture measurement.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] Please refer to the following: Figure 1 and Figure 2 One embodiment of this application provides a detection device 100 for detecting a fixture 200. The fixture 200 includes a locking member 210 configured to lock into a carrier (not shown) to secure a workpiece (not shown) mounted on the carrier.

[0023] For example, the locking element 210 is a copper pillar, and the carrier has a through hole (not shown). When the clamp 200 is placed on the carrier, the copper pillar can pass through the through hole and engage with the carrier to lock the clamp 200 and the carrier together. In other embodiments, the locking element 210 may be other types, and this application does not limit it. Those skilled in the art can choose according to the actual situation.

[0024] Please refer to the following: Figure 1 , Figure 3 as well as Figure 4 In some embodiments, the detection device 100 includes a frame 10, a conveying mechanism 20, a handling mechanism 30, and a detection mechanism 40. The frame 10 is provided with a detection station 11, which is configured for the detection mechanism 40 to detect the locking member 210 to determine whether the locking member 210 meets the requirements for locking and engaging with the carrier.

[0025] In some embodiments, the conveying mechanism 20 is mounted on the frame 10 and configured to carry and convey the fixture 200. The conveying mechanism 20 has a gripping station 21. Understandably, after the fixture 200 is placed on the conveying mechanism 20, the conveying mechanism 20 can move the fixture 200 to the gripping station 21 to await transport by the handling mechanism 30 for the next inspection operation, which is beneficial for automating the inspection device 100.

[0026] Please refer to the following: Figure 1 , Figure 3 and Figure 5In some embodiments, the conveying mechanism 20 is further provided with a barcode scanning station 22, which is distributed along the conveying direction of the fixture 200 with the gripping station 21. The fixture 200 is configured to pass through the barcode scanning station 22 and the gripping station 21 in sequence.

[0027] Understandably, when the conveyor 20 transports the fixture 200, the fixture 200 moves to the barcode scanning station 22 for barcode scanning and marking. Then, it moves to the gripping station 21. The barcode scanning station 22 facilitates the barcode identification of multiple fixtures 200, making subsequent tracking of the fixtures 200 easier.

[0028] For example, when a fixture 200 is detected to be non-compliant with the requirements for locking with the carrier, technicians can quickly locate the fixture 200 based on the information obtained after scanning the code, which helps reduce the risk of non-compliant fixtures 200 entering the production line.

[0029] In some embodiments, the scanning station 22 and the gripping station 21 can be set apart or side by side. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0030] Please see Figure 5 For example, the conveying mechanism 20 includes a conveyor line 23, a barcode scanning assembly 24, and a stop assembly 25. The conveyor line 23 is mounted on the frame 10 and has the aforementioned barcode scanning station 22 and gripping station 21. The conveyor line 23 is configured as a conveying fixture 200. The barcode scanning assembly 24 and the stop assembly 25 are both mounted on the conveyor line 23 and located at the barcode scanning station 22.

[0031] When the fixture 200 is placed on the conveyor line 23, the conveyor line 23 moves the fixture 200 to the barcode scanning station 22. The stop assembly 25 rises and blocks the fixture 200. At this time, the barcode scanning assembly 24 scans the identification code in the fixture 200. After the scanning is completed, the stop assembly 25 descends, and the conveyor line 23 continues to move the fixture 200 until it reaches the gripping station 21.

[0032] Please refer to the following: Figure 1 , Figure 3 as well as Figure 4 In some embodiments, the conveying mechanism 30 includes a first drive assembly 31 and a gripper assembly 32, the first drive assembly 31 being connected to the gripper assembly 32. The first drive assembly 31 is configured to drive the gripper assembly 32 to move such that the gripper assembly 32 conveys the fixture 200 between the gripping station 21 and the inspection station 11.

[0033] With the addition of the conveying mechanism 30, the fixture 200 can be moved manually without human intervention, which helps to improve the automation level of the detection device 100 and thus improve the detection efficiency of the detection device 100.

[0034] For example, when the conveying mechanism 20 transports the fixture 200 to the gripping station 21, the first drive component 31 drives the gripper assembly 32 to move to the gripping station 21. At this time, the gripper assembly 32 grips the fixture 200 in the gripping station 21. After the gripper assembly 32 grips the fixture 200, the first drive component 31 then drives the gripper assembly 32 to move to the inspection station 11. At this time, the gripper assembly 32 places the fixture 200 in the inspection station 11.

[0035] Please refer to the following: Figure 1 , Figure 3 as well as Figure 4 In some embodiments, the detection mechanism 40 includes a pressure detection component 41, a concentricity detection component 42, and a distance detection component 43. The pressure detection component 41, the concentricity detection component 42, and the distance detection component 43 are all mounted on the frame 10, and all three are located at the detection station 11.

[0036] The pressure detection component 41 is configured to detect the weight of the locking member 210, the concentricity detection component 42 is configured to detect the concentricity of the locking member 210, and the distance detection component 43 is configured to detect the movement distance of the locking member 210 (specifically, the limit distance of the movement of the locking member 210) in order to determine whether the locking member 210 meets the requirements for locking and engaging with the vehicle.

[0037] Specifically, the measured weight of locking component 210 is compared with its initial weight. If the weight of locking component 210 changes, it indicates that the structure of locking component 210 has become loose (e.g., a component has fallen off), or that locking component 210 has worn / deformed (e.g., wear leading to uneven mass distribution), and locking component 210 does not meet the requirements for locking with the vehicle. Conversely, if the weight does not change, it indicates that locking component 210 meets the requirements for locking with the vehicle.

[0038] If the concentricity of the locking component 210 is measured to be off, it indicates that the locking component 210 has problems such as deformation, and the locking component 210 does not meet the requirements for locking with the vehicle. Conversely, it indicates that the locking component 210 meets the requirements for locking with the vehicle.

[0039] The measured movement distance of locking component 210 is compared with its initial movement distance. If the movement distance exceeds the preset value, it indicates that locking component 210 is loose and does not meet the requirements for locking with the vehicle. Conversely, if the movement distance is less than the preset value, it indicates that locking component 210 meets the requirements for locking with the vehicle.

[0040] The detection device 100 provided in this application, through the cooperation of the conveying mechanism 20, the handling mechanism 30 and the detection mechanism 40, can detect multiple parameters (i.e., weight, concentricity and moving distance) of the locking part 210. This not only helps to improve the detection efficiency of the fixture 200 and save manpower, but also helps to reduce the error of manual measurement and improve the measurement accuracy of the fixture 200.

[0041] In other embodiments, the detection mechanism 40 may be provided with a pressure detection component 41, a concentricity detection component 42, or a distance detection component 43 separately. Alternatively, the detection mechanism 40 may be provided with any two of the pressure detection component 41, the concentricity detection component 42, and the distance detection component 43 simultaneously. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0042] In some embodiments, the pressure detection component 41, the concentricity detection component 42, and the distance detection component 43 are configured to simultaneously detect the locking member 210. Specifically, when the fixture 200 is located at the detection station 11, the pressure detection component 41, the concentricity detection component 42, and the distance detection component 43 can simultaneously detect the locking member 210 to obtain the weight, concentricity, and movement distance of the locking member 210.

[0043] By configuring the pressure detection component 41, the concentricity detection component 42, and the distance detection component 43 to simultaneously detect the locking member 210, it is beneficial to further improve the detection efficiency of the detection device 100.

[0044] Please see Figure 3 In some embodiments, the detection station 11 includes a first detection position 12 and a second detection position 13, which are arranged in a specific order. The pressure detection component 41 is located at the first detection position 12, and the concentricity detection component 42 and the distance detection component 43 are located at the second detection position 13.

[0045] By setting two detection positions (specifically, the first detection position 12 and the second detection position 13), step-by-step detection of the locking member 210 can be achieved, which helps to improve the flexibility of the detection device 100.

[0046] For example, when the pressure detection component 41 located at the first detection position 12 fails, the clamp 200 can be moved directly to the second detection position 13, and the concentricity detection component 42 and the distance detection component 43 can detect the concentricity and movement distance of the locking member 210, without the detection device 100 needing to stop.

[0047] Please refer to the following: Figure 1 , Figure 3 as well as Figure 6In some embodiments, the detection device 100 further includes a positioning and transfer mechanism 50, which is mounted on the frame 10. The positioning and transfer mechanism 50 is configured to carry the fixture 200 and drive the fixture 200 to a first detection position 12 or a second detection position 13.

[0048] When the clamp 200 is in the first detection position 12, the pressure detection component 41 is configured to detect the weight of the locking member 210. When the clamp 200 is in the second detection position 13, the concentricity detection component 42 is configured to detect the concentricity of the locking member 210, and the distance detection component 43 is configured to detect the movement distance of the locking member 210.

[0049] By setting up the positioning and transfer mechanism 50, the fixture 200 can be automatically transported, which helps to save manpower, further improve the automation level of the detection device 100, and thus improve the detection efficiency of the detection device 100.

[0050] Specifically, the positioning and transfer mechanism 50 includes a second drive assembly 51 and a carrier 52. The second drive assembly 51 is mounted on the frame 10 and connected to the carrier 52. The carrier 52 is configured as a loading fixture 200. The second drive assembly 51 is configured to drive the carrier 52 to either a first detection position 12 or a second detection position 13.

[0051] For example, in the initial state, the carrier 52 is located at the first detection position 12. The transport mechanism 30 transfers the clamp 200 onto the carrier 52, and the pressure detection component 41 detects the weight of the locking member 210. After the weight detection of the locking member 210 is completed, the second drive component 51 drives the carrier 52 to move to the second detection position 13, the concentricity detection component 42 detects the concentricity of the locking member 210, and the distance detection component 43 detects the moving distance of the locking member 210.

[0052] Please see Figure 6 In some embodiments, the carrier 52 is provided with an assembly position 521, which is configured to receive the clamp 200. For example, the carrier 52 is recessed to form the assembly position 521, and the clamp 200 is received in the assembly position.

[0053] In other embodiments, the assembly position 521 may also be formed by a protrusion. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0054] In some embodiments, the positioning and transfer mechanism 50 further includes a laser assembly 53 mounted on the carrier 52 and located around the assembly position 521. The laser assembly 53 is configured to illuminate the assembly position 521 to detect whether the clamp 200 is tilted.

[0055] The laser component 53 helps ensure that the fixture 200 is accurately mounted on the carrier 52, reducing the risk of increased measurement errors in the concentricity detection component 42 and the movement distance detection component 43 due to the fixture 200 tilting.

[0056] For example, a preset laser irradiation angle is used. After the fixture 200 is mounted on the carrier 52, the laser assembly 53 is activated. If the laser beam emitted by the laser assembly 53 is flush with the top surface of the fixture 200, it indicates that the fixture 200 is mounted flat on the carrier 52. If the laser beam emitted by the laser assembly 53 is not flush with the top surface of the fixture 200, it indicates that the fixture 200 is not mounted flat on the carrier 52.

[0057] Please refer to the following: Figure 3 , Figure 7 as well as Figure 8 In some embodiments, the pressure detection assembly 41 includes a first drive 411, a pressure sensor 412, and a first probe 413. The first drive 411 is mounted on the frame 10, the pressure sensor 412 is connected to the first drive 411, and the first probe 413 is mounted on the pressure sensor 412.

[0058] The first driving member 411 is configured to drive the pressure sensor 412 to move, so that the first probe 413 abuts against the locking member 210 and acts on the pressure sensor 412 to obtain the weight of the locking member 210. By cooperating with the pressure sensor 412 and the first probe 413, the gravity of the locking member 210 can be accurately measured, which helps to improve the detection accuracy of the detection device 100 and reduce measurement errors.

[0059] Specifically, the first probe 413 includes a needle body 4131, an elastic part (not shown) and a bushing 4132. The bushing 4132 is installed on the pressure sensor 412. The needle body 4131 slides through the bushing 4132. The elastic part is sleeved on the needle body 4131, with one end of the elastic part abutting against the needle body 4131 and the other end abutting against the pressure sensor 412.

[0060] Understandably, when it is necessary to detect the weight of the locking member 210, the first driving member 411 drives the pressure sensor 412 and the first probe 413 to move closer to the locking member 210. When the needle body 4131 of the first probe 413 abuts against the locking member 210, as the pressure sensor 412 and the first probe 413 move, the needle body 4131 will gradually lift the locking member 210 and retract the holding elastic part relative to the bushing 4132. The end of the elastic part away from the locking member 210 acts on the pressure sensor 412, and the pressure sensor 412 produces a numerical change after being subjected to the pressure of the elastic part.

[0061] When the first probe 413 lifts the locking member 210 to the target position (specifically, when the elastic force of the elastic part in the first probe 413 is equal to the weight of the locking member 210), the first drive member 411 stops driving the pressure sensor 412 and the first probe 413 to move. At this time, the value displayed by the pressure sensor 412 is the weight of the locking member 210.

[0062] In other embodiments, other structures may be used to measure the weight of the locking member 210. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0063] Please see Figure 8 In some embodiments, the needle body 4131 is provided with a limiting part 41311, and the bushing 4132 is provided with a limiting surface 41321. The limiting part 41311 and the limiting surface 41321 cooperate to constrain the relative position of the needle body 4131 and the bushing 4132.

[0064] By setting the limiting part 41311 and the limiting surface 41321, the risk of damage to the pressure sensor 412 or the first probe 413 caused by the needle body 4131 moving too far relative to the bushing 4132 can be reduced, which is beneficial to extending the service life of the detection device 100.

[0065] Please refer to the following: Figure 1 , Figure 3 as well as Figure 9 In some embodiments, the fixture 200 includes a top surface (not shown) and a clamping surface (not shown) disposed opposite to each other, the clamping surface being configured to abut against the workpiece. The concentricity detection assembly 42 includes a first visual imager 421 and a second visual imager 422, both of which are mounted on the frame 10 and located on opposite sides of the detection station 11 (specifically, the side closer to the top surface of the fixture 200 and the side closer to the clamping surface of the fixture 200).

[0066] The first visual image sensor 421 is configured to acquire an image of the top surface of the fixture 200, and the second visual image sensor 422 is configured to acquire an image of the clamping surface of the fixture 200, in order to determine the concentricity of the locking member 210. By employing image processing, the detection accuracy of the detection device 100 is improved, and measurement errors are reduced.

[0067] For example, when it is necessary to detect the concentricity of the locking member 210, the first visual imager 421 acquires an image of the top surface of the clamp 200 and calculates the coordinates of the locking member 210 on the top surface of the clamp 200. The second visual imager 422 acquires an image of the clamping surface of the clamp 200 and calculates the coordinates of the locking member 210 on the clamping surface of the clamp 200. By fitting circles in the image of the top surface of the clamp 200 and circles in the image of the clamping surface of the clamp 200, and calculating the distance between the centers of the two circles, the concentricity deviation of the locking member 210 can be obtained.

[0068] In other embodiments, other structures may be used to measure the concentricity of the locking member 210. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0069] Please refer to the following: Figure 1 , Figure 3 as well as Figure 9 In some embodiments, the distance detection component 43 includes a second drive 431, a second probe 432, and a displacement sensor 433. The second drive 431 is mounted on the frame 10, and the second probe 432 is connected to the second drive component 51.

[0070] The second driving member 431 is configured to drive the second probe 432 to move, so that the second probe 432 drives the locking member 210 to its limit position (specifically, the maximum distance the second probe 432 moves against the locking member 210). The displacement sensor 433 is configured to acquire the moving distance of the locking member 210. By cooperating with the displacement sensor 433 and the second probe 432, the moving distance of the locking member 210 can be accurately measured, which helps to improve the detection accuracy of the detection device 100 and reduce measurement errors.

[0071] For example, when it is necessary to measure the moving distance of the locking member 210, the displacement sensor 433 measures the top surface height of the locking member 210 in the initial state (specifically, when the locking member 210 has not moved) and generates a first height. The second drive member 431 drives the second probe 432 to move closer to the locking member 210, and the second probe 432 gradually lifts the locking member 210 until the locking member 210 moves to its limit position. The displacement sensor 433 measures the top surface height of the locking member 210 again and generates a second height. The moving distance of the locking member 210 can be obtained by calculating the difference between the first height and the second height.

[0072] In other embodiments, other structures may be used to measure the movement distance of the locking member 210. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0073] For example, the detection process of the detection device 100 provided in this application is as follows: the conveying mechanism 20 transports the fixture 200 to the barcode scanning station 22, and the barcode scanning component 24 scans the fixture 200. After the barcode scanning is completed, the conveying mechanism 20 continues to transport the fixture 200 to the gripping station 21, and the handling mechanism 30 moves the fixture 200 from the gripping station 21 to the first detection position 12 in the detection station 11.

[0074] The pressure detection component 41 measures the weight of the locking member 210. After the pressure detection component 41 completes the measurement, the positioning and transfer mechanism 50 transports the fixture 200 to the second detection position 13 in the detection station 11. The concentricity detection component 42 measures the concentricity of the locking member 210, and the distance detection component 43 measures the moving distance of the locking member 210.

[0075] It is worth noting that the pressure detection component 41, the concentricity detection component 42, and the distance detection component 43 do not have a specific order for detecting the locking element 210, and those skilled in the art can choose according to the actual situation.

[0076] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
