Description

Technical Field

[0001] The utility model relates to the technical field of detection instruments, in particular to a coding sensor detection device. Background Art

[0002] With the improvement of people's living standards and the advancement of industrial automation, the application occasions of encoding sensors are increasing, and the market demand for high-precision encoding sensors is rising, which has greatly promoted the research and development and production process of encoding sensors and encoding sensor detection devices.

When the second rotating shaft stops rotating intermittently, the detection module located at the bottom of the detection target area of ​​the code disk can be used to perform quality inspection on the coding sensor to be tested located at the top of the detection target area of ​​the code disk. After the inspection is completed, the next coding sensor to be tested can be retrieved again for inspection.

The inspection has a high degree of automation, is convenient to operate, and can be continuously inspected, thereby greatly improving work efficiency.

After the power assembly transmits the rotating force to the third rotating shaft, the groove wheel can be intermittently rotated through the cooperation of the turntable, the dial, the fixed block and the dial column, so that the second rotating shaft can be synchronously intermittently rotated. Since the number of the dial grooves on the groove wheel is the same as the number of the retrieval plate, and the central axes coincide with each other, the negative pressure suction cup on the retrieval plate and the coding sensor to be tested at the bottom of the negative pressure suction cup can be accurately rotated to the specified position each time the groove wheel is intermittently rotated. At the same time, during the period when the second rotating shaft intermittently stops rotating, the coding sensor to be tested is provided with a detection time, and then the effect of automatic retrieval can be achieved after the detection is completed, thereby improving the overall degree of automation.

DETAILED DESCRIPTION

[0028] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a coding sensor detection device includes: a workbench 1, a base plate 11 fixed to the bottom of the workbench 1 by a connecting rod, and a first rotating shaft 12 and a second rotating shaft 13 arranged on the workbench 1; a chuck 2 is fixed to the top of the first rotating shaft 12, a code disk 21 is fixed on the chuck 2, and a detection signal output by the coding sensor to be tested when the code disk 21 rotates is fixed on the top of the workbench 1.

[0030] A calling assembly is arranged at the top of the second rotating shaft 13, and the calling assembly includes: a fixed disk 3 fixed on the top of the second rotating shaft 13, a plurality of calling plates 31 fixed on the side of the fixed disk 3, and a negative pressure suction cup 32 fixed on the calling plate 31; an intermittent rotating assembly for providing intermittent rotation to the second rotating shaft 13 is arranged between the workbench 1 and the base plate 11, and a power assembly for providing rotational force to the first rotating shaft 12 and the intermittent rotating assembly is arranged on the base plate 11.

[0031] It should be noted that the top of the target area of ​​the code disk 21 during detection is opposite to the bottom of the negative pressure suction cup 32, and the bottom of the target area of ​​the code disk 21 during detection is opposite to the detection end of the detection module 22; the side surfaces of the first rotating shaft 12 are rotatably connected to the inner sides of the workbench 1 and the bottom plate 11 respectively, and the side surfaces of the second rotating shaft 13 are rotatably connected to the inner side of the workbench 1, and a number of retrieval plates 31 are evenly distributed on the side surfaces of the fixed disk 3 in the circumferential direction; the detection module 22 is electrically connected to the coding sensor to be tested, and the connection end of the negative pressure suction cup 32 is connected to an external negative pressure device; when a large number of coding sensors need to be detected, a plurality of coding sensors to be tested are respectively contacted to the bottom ends of the negative pressure suction cup 32, and the external negative pressure device is started, and negative pressure is generated by the bottom ends of the negative pressure suction cup 32, so that the coding sensor to be tested is adsorbed onto the negative pressure suction cup 32 to complete the pre-installation, and the power assembly provides rotational power to the first rotating shaft 12 and the intermittent rotating assembly, and the rotation of the first rotating shaft 12 will cause the code disk 21 to rotate rapidly. At the same time, the rotation of the intermittent rotating component will intermittently drive the second rotating shaft 13 and the fixed disk 3, the retrieval plate 31 and the negative pressure suction cup 32 on the second rotating shaft 13 to rotate intermittently, so that the next coding sensor to be tested is intermittently retrieved and moved to the detection target area on the top of the code disk 21. When the second rotating shaft 13 stops rotating intermittently, the energized coding sensor to be tested generates a pulse signal along with the scale / grating of the code disk 21. The pulse signal is detected by the detection end of the detection module 22, thereby judging whether the coding sensor to be tested meets the quality requirements. At this time, the quality inspection of the coding sensor to be tested located at the top of the detection target area of ​​the code disk 21 can be carried out. After the second rotating shaft 13 is rotated again, the next coding sensor to be tested can be retrieved again for inspection. The staff only needs to remove the coding sensor that has been inspected and install the coding sensor to be tested under the negative pressure suction cup 32. The inspection has a high degree of automation, convenient operation and continuous inspection, thereby greatly improving work efficiency.

[0032] The first rotating shaft 12 is located on the side of the top of the workbench 1 and is installed with a first bearing seat 6, and the bottom of the first bearing seat 6 is fixed to the top of the workbench 1. The second rotating shaft 13 is located on the side of the top of the workbench 1 and is installed with a second bearing seat 61, and the bottom of the second bearing seat 61 is fixed to the top of the workbench.

[0033] It should be noted that the inner ring of the first bearing seat 6 is fixed to the side of the first rotating shaft 12, and the first bearing seat 6 can play a role in stabilizing the rotation of the first rotating shaft 12; the inner ring of the second bearing seat 61 is fixed to the side of the second rotating shaft 13, and the second bearing seat 61 can play a role in stabilizing the rotation of the second rotating shaft 13.

[0034] A plurality of supporting legs 7 are fixed to the bottom of the workbench 1 ; the arrangement of the plurality of supporting legs 7 can provide support for the workbench 1 .

[0035] like Figure 2 and Figure 3 As shown, the intermittent rotating assembly includes: a groove wheel 4 fixed on the second rotating shaft 13 at one end of the bottom of the workbench 1, a third rotating shaft 41 rotatably connected between the workbench 1 and the base plate 11, and a turntable 42 and a dial 43 fixed on the side of the third rotating shaft 41; a fixed block 44 is fixed on the side of the turntable 42, and a dial post 45 is fixed on the side of the fixed block 44 facing the groove wheel 4, and the side of the dial post 45 is slidably connected to the inner side of the dial groove of the groove wheel 4.

[0036] It should be noted that the number of the grooves of the groove wheel 4 is the same as the number of the call plate 31, and the central axes coincide with each other; the dial 43 and the groove wheel 4 are located in the same plane, and the diameter of the dial 43 is the same as the diameter of the arc-shaped outer ring of the groove wheel 4; when the power component transmits the rotational force to the third rotating shaft 41, it will drive the turntable 42 and the dial 43 on the side of the third rotating shaft 41 to rotate synchronously, and the turntable 42 will drive the fixed block 44 on the side and the lever 45 on the side of the fixed block 44 to move. When the lever 45 moves to the inner side of the groove of the groove wheel 4, it can slide inside the groove and dial the groove wheel 4 and the second rotating shaft 13 for intermittent rotation. The dial plate 43 is rotated to the left and right sides of the groove wheel 43, and the number of the grooves on the groove wheel 4 is the same as the number of the retrieval plate 31, and the central axes coincide with each other. The negative pressure suction cup 32 on the retrieval plate 31 and the coding sensor to be tested at the bottom of the negative pressure suction cup 32 can be accurately rotated to the specified position every time the groove wheel 4 is rotated intermittently. At the same time, during the period when the second rotating shaft 13 intermittently stops rotating, the coding sensor to be tested is provided with a detection time, and then the effect of automatic retrieval can be achieved after the detection is completed, thereby improving the overall degree of automation.

[0037] like Figure 3 and Figure 4 As shown, the power assembly includes: a servo motor 5 fixed at the bottom of the base plate 11, a driving synchronous pulley 51 fixed at the output end of the servo motor 5 located at the top of the base plate 11, and a first driven synchronous pulley 52 fixed on the side of the third rotating shaft 41; the inner sides of the driving synchronous pulley 51 and the first driven synchronous pulley 52 are meshed with a first toothed belt 53.

[0038] The power assembly further includes: a second driven synchronous pulley 54 fixed to the side of the first rotating shaft 12 , and a second toothed belt 55 meshed with the driving synchronous pulley 51 and the inner side of the second driven synchronous pulley 54 .

[0039] It should be noted that the diameter of the active synchronous pulley 51 is smaller than the diameter of the first driven synchronous pulley 52, and the diameter of the second driven synchronous pulley 54 is greater than the diameter of the second driven synchronous pulley 54; the servo motor 5 is started to drive the active synchronous pulley 51 to rotate, and the first driven synchronous pulley 52 and the third rotating shaft 41 can be driven to rotate through the engagement of the first toothed belt 53. Since the diameter of the active synchronous pulley 51 is smaller than the diameter of the first driven synchronous pulley 52, the rotation speed of the third rotating shaft 41 is reduced, thereby controlling the rotation frequency during intermittent rotation, so that enough detection time is reserved for the encoder sensor to be tested after being called up. While the active synchronous pulley 51 rotates, the second driven synchronous pulley 54 and the first rotating shaft 12 can be driven to rotate through the engagement of the second toothed belt 55, so that the code disk 21 at the top of the first rotating shaft 12 is driven to rotate. Since the diameter of the active synchronous pulley 51 is larger than the diameter of the second driven synchronous pulley 54, the rotation speed of the first rotating shaft 12 is increased, so that the code disk 21 can rotate quickly to complete the rotation frequency required for detection.

[0040] When the utility model is used, when a large number of coding sensors need to be tested, a plurality of coding sensors to be tested are respectively contacted to the bottom end of the negative pressure suction cup 32, and the external negative pressure device is started, and the negative pressure is generated by the bottom end of the negative pressure suction cup 32, so that the coding sensor to be tested is adsorbed on the negative pressure suction cup 32 to complete the pre-installation, and the servo motor 5 is started to drive the active synchronous belt wheel 51 to rotate, and the second driven synchronous belt wheel 54 and the first rotating shaft 12 can be driven to rotate through the engagement of the second toothed belt 55, so that the coding sensors at the top of the first rotating shaft 12 are driven to rotate. The disk 21 rotates, and the first driven synchronous pulley 52 and the third rotating shaft 41 are driven to rotate through the meshing of the first toothed belt 53, which will drive the turntable 42 and the dial 43 on the side of the third rotating shaft 41 to rotate synchronously. The turntable 42 will drive the fixed block 44 on the side and the lever 45 on the side of the fixed block 44 to move. When the lever 45 moves to the inner side of the lever groove of the groove wheel 4, it can slide inside the lever groove and drive the groove wheel 4 and the second rotating shaft 13 to rotate intermittently. After the lever 45 is out of the lever groove, the side of the dial 43 will be in contact with the The arc-shaped outer ring of the groove wheel 4 is fitted to play the role of locking and limiting. Since the number of the grooves on the groove wheel 4 is the same as the number of the retrieval plate 31, and the central axes coincide with each other, the negative pressure suction cup 32 on the retrieval plate 31 and the coding sensor to be tested at the bottom of the negative pressure suction cup 32 can be accurately rotated to the detection target area at the top of the code disk 21 every time the groove wheel 4 is rotated intermittently. When the second rotating shaft 13 stops rotating intermittently, the energized coding sensor to be tested generates a pulse signal along with the scale / grating of the code disk 21. The pulse signal is detected by the detection end of the detection module 22, thereby judging whether the coding sensor to be tested meets the quality requirements. At this time, the coding sensor to be tested located at the top of the detection target area of ​​the code disk 21 can be quality tested. After the second rotating shaft 13 is rotated again, the next coding sensor to be tested can be retrieved again for testing. The staff only needs to remove the coding sensor that has been tested and install the coding sensor to be tested under the negative pressure suction cup 32. The detection is highly automated, the operation is convenient, and continuous detection is possible, thereby greatly improving the work efficiency.

[0041] The above is based on the ideal embodiment of the utility model. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the utility model.
