Description

Technical Field

[0002] Steel tape measures can be divided into self-winding tape measures, brake tape measures, and rocking tape measures. They are tools for measuring the size or distance of longer workpieces and are also commonly used measuring tools in daily life. What we often see are steel tape measures, which are commonly used in construction and decoration, and are also one of the essential tools in the home.

[0003] During the production and processing of steel tape measures, it is often necessary to use specific calibration devices to conduct factory inspection on the steel tape measures. During the inspection process of the steel tape measures, not only the scale accuracy of the steel tape measures must be tested, but also the length of the steel tape measures must be tested. When the existing devices detect the length of the steel tape measures, the steel tape measures are usually pulled out from the inside of the body. When the steel tape measures are too long, certain requirements are required for the inspection site, and it is not convenient for the staff to operate. In addition, when the steel tape measures are being tested, dust and stains may adhere to the surface of the steel tape measures, covering or blurring the scale lines, thereby affecting the accurate reading of the scale during the calibration process, and then leading to errors in the inspection process.

[0024] Specifically, the control panel 35 of the present device adopts PLC output signals to control the power on and off of the coils of the relay and contactor, which can then control the counting status of the various motors and counters 8 of the present device. Controlling each output device through the control panel 35 is a common technology in the industry, so its specific principles will not be elaborated here. The present device adopts an industrial digital camera 54 to collect the scale image of the steel tape measure, and uses computer real-time image processing technology to identify the physical coordinate position of the line pattern, and calibrate the scale accuracy of the steel tape measure. This calibration method is a commonly used method in the industry, so its specific principles will not be elaborated here.

[0025] Please see the attached Figure 2 The linkage assembly includes a connecting worm 10, a first worm wheel 11, a first connecting belt 12, a driving gear 13, a driven gear 14 and a second connecting belt 15. The first worm wheel 11 is fixedly mounted on one end of the roller 17. The connecting worm 10 is meshed with the first worm wheel 11. The second connecting belt 15 is connected to the connecting worm 10 and the grinding disc 16 through pulleys. The first connecting belt 12 is connected to the roller 17 and the driving gear 13 through pulleys. The driven gear 14 is arranged on one side of the driving gear 13 and is meshed with it.

[0026] Specifically, the grinding disc 16 is rotatably connected to the top surface of the base plate 1 through a rotating shaft, and the second connecting belt 15 connects the rotating shaft on the bottom surface of the grinding disc 16 and the connecting worm 10 through a pulley, so that when the connecting worm 10 rotates, the second connecting belt 15 can be driven by the pulley to transmit the power, and the second connecting belt 15 can drive the grinding disc 16 to rotate between the two vertical plates 2, and when the connecting worm 10 rotates, it can drive the first worm gear 11 to rotate, and the first worm gear 11 can drive the cleaning brush 18 to rotate through the roller 17, and the grinding disc 16 and the cleaning brush 18 rotate at the same time. When calibrating the steel tape measure, the steel tape measure can be placed between the cleaning brush 18 and the grinding disc 16, and the burrs on the bottom surface of the steel tape measure can be polished by the grinding disc 16, and the dust and impurities attached to the surface of the steel tape measure can be removed by the cleaning brush 18. The cleaning process prevents dust and impurities attached to the surface of the steel tape from affecting the calibration accuracy, and also prevents burrs from affecting the smoothness of pulling out or recovering the steel tape. When the first worm gear 11 drives the rotating roller 17 to rotate, the first connecting belt 12 can also be driven by the pulley to transmit the power, and the first connecting belt 12 drives the driving gear 13 to rotate, and the driving gear 13 can drive the winding roller 20 to rotate. When calibrating the steel tape, the steel tape can be positioned on the winding roller 20, and the steel tape can be wound by rotating the winding roller 20. When the steel tape is wound, the steel tape can be pulled, and the steel tape can be slowly wound in sequence. The steel tape can be calibrated by the industrial digital camera 54 between the two vertical plates 2, thereby increasing the convenience of calibrating the steel tape.

[0027] Please see the attached Figure 2 A drive motor 9 is provided on the top surface of the base plate 1, and the output end of the drive motor 9 is connected to the connecting worm 10. One side of the driven gear 14 is connected to the counter 8 through a connecting shaft. A drive shell 5 is fixedly installed on one side of one of the two vertical plates 2, and the first worm gear 11 is connected to the inner wall of the drive shell 5 through a rotating shaft. The winding roller 20 is fixedly connected to the driving gear 13 through a connecting shaft.

[0028] Specifically, by turning on the drive motor 9, the drive motor 9 can drive the connecting worm 10 to rotate. When the connecting worm 10 rotates, the second connecting belt 15 and the first connecting belt 12 can drive the roller 17 and the driving gear 13 to rotate in linkage. When the driving gear 13 rotates, it can drive the driven gear 14 to rotate. The number of circles when the driven gear 14 rotates can be recorded by the counter 8. The rotation of the driving gear 13 can drive the winding roller 20 to rotate. The winding roller 20 rotates one circle to rewind the steel tape to a fixed length. At the same time, the rotation of the driving gear 13 can drive the driven gear 1 4 rotates, so the rotation of the winding roller 20 can be recorded by the counter 8, and then the wound length of the steel tape can be recorded. In actual use, the length of the steel tape can be calculated by multiplying the number of revolutions of the winding roller 20 by the circumference of the winding roller 20 and adding the exposed length of the steel tape, thereby facilitating the staff to verify the length of the steel tape. The verification process is extremely simple, greatly increasing the convenience of verification. The first worm gear 11 is rotatably connected to the drive housing 5 via the rotating shaft, thereby ensuring the stable rotation of the first worm gear 11 inside the drive housing 5.

[0029] Please see the attached Figure 5 The inner side of the clamping frame 4 is symmetrically provided with clamping plates 25, one side of the two clamping plates 25 is fixedly connected with a pull block 26, a pull rope 27 is fixedly connected between the two pull blocks 26, the center of the pull rope 27 is fixedly connected with a fixed block 32, one side of the fixed block 32 is fixedly connected with a pull ring 33, and two telescopic rods 28 are provided between the inner side of the clamping frame 4 and the two clamping plates 25.

[0030] Specifically, both ends of the pull rope 27 pass through the clamping frame 4. By pulling the pull ring 33, the pull ring 33 can pull the pull rope 27 through the fixed block 32. The pull rope 27 can pull the pull block 26, and the pull block 26 can pull the clamping plates 25 to both sides. The two clamping plates 25 move to both sides to adjust the distance between the two clamping plates 25. At this time, the steel tape measure body can be placed between the two clamping plates 25, and the steel tape measure body can be clamped by the two clamping plates 25.

[0031] Please see the attached Figure 5 -Attached Figure 6 A first spring 34 is provided inside the telescopic rod 28, a rubber plate 24 is fixedly installed on one side of the two clamping plates 25, a first pulley 29 is fixedly installed on one side of the clamping frame 4 through a fixing frame, and the pull rope 27 is wound around the surface of the first pulley 29, and two second pulleys 31 are fixedly installed on one side of the clamping frame 4 through a fixing frame, and the pull rope 27 is wound around the surface of the second pulley 31.

[0032] Specifically, by winding the pull rope 27 around the first pulley 29 and the second pulley 31, the smoothness of pulling the pull rope 27 can be guaranteed. Since the pull block 26 is fixedly arranged at the center of one side of the splint 25, when the pull rope 27 pulls the splint 25, the force point of the splint 25 will be at the center of the splint 25, thereby ensuring the stability of the splint 25 when it moves to both sides. The telescopic rod 28 is divided into an inner rod and an outer rod, and the two ends of the first spring 34 inside it are connected to the inner rod and the outer rod respectively. Therefore, when the two splints 25 move to both sides, the telescopic rod 28 can be driven to move. The inner rod of the retracting rod 28 extends and contracts inwardly, and when the inner rod extends and contracts, it squeezes the first spring 34 inwardly. When the clamping plate 25 is no longer under force, the first spring 34 pushes the inner rod to reset, and the inner rod pushes the clamping plate 25 to move. The force of the first spring 34 can push the two clamping plates 25 to clamp the steel tape measure body, thereby ensuring the stability of the steel tape measure body during calibration. Rubber plates 24 are provided on the surfaces of the two clamping plates 25 to protect the steel tape measure body and prevent it from being damaged due to excessive clamping force.

[0033] Please see the attached Figure 7 A positioning groove 23 is formed on the surface of the winding roller 20 , and a bolt 36 is passed through the inner wall of the positioning groove 23 . One end of the bolt 36 is connected to a positioning plate 37 , and the positioning plate 37 is arranged inside the positioning groove 23 .

[0034] Specifically, a screw hole corresponding to the bolt 36 is opened inside the positioning groove 23. By rotating the bolt 36, the bolt 36 can push the positioning plate 37 to move inside the positioning groove 23. When calibrating the steel tape measure, the end of the steel tape measure can be inserted into the interior of the positioning groove 23. By rotating the bolt 36, the positioning plate 37 can be driven to move. By clamping the end of the steel tape measure with the positioning plate 37, the steel tape measure can be fixed on the winding roller 20, thereby facilitating the winding and calibration of the steel tape measure.

[0035] Please see the attached Figure 2 and attached Figure 8 The lifting assembly includes a screw 39, a connecting rod 40, a moving block 46, a second worm gear 42 and a double-section worm 43. The two moving blocks 46 are respectively arranged inside the lifting groove 22, and the moving blocks 46 are slidingly connected to the lifting groove 22. The two screws 39 are respectively passed through the two moving blocks 46. The two connecting rods 40 are respectively fixedly mounted on the bottom ends of the two screws 39. The two second worm gears 42 are respectively fixedly mounted on the bottom ends of the two connecting rods 40. The double-section worm 43 is meshed with the two second worm gears 42. The two moving blocks 46 are fixedly mounted on both sides of the disassembly and assembly seat 38.

[0036] Specifically, the moving block 46 and the screw 39 are connected by a threaded connection, so that when the two screws 39 rotate synchronously in the same direction, the two moving blocks 46 can be driven to move synchronously. When the two moving blocks 46 move synchronously, the disassembly and assembly seat 38 can be driven to rise and fall, and the disassembly and assembly seat 38 can drive the top shell 19 to rise and fall, and the shell 19 can drive the industrial digital camera 54 on the bottom to rise and fall, so that the height of the industrial digital camera 54 can be adjusted, which is convenient for focusing on the scale line of the steel tape measure and more conducive to its calibration. The double-segment worm 43 is meshed with the two second worm gears 42, so that when the double-segment worm 43 drives the two worm gears to rotate synchronously in the same direction, the two worm gears can drive the two connecting rods 40 to rotate synchronously in the same direction, and the connecting rod 40 can drive the two screws 39 to rotate synchronously and in the same direction.

[0037] Please see the attached Figure 1 and attached Figure 8 A lifting motor 6 is fixedly installed on one side of the base plate 1 through a fixed frame, and the output end of the lifting motor 6 is connected to the double-section worm 43. A guide rod 41 is respectively provided inside the two lifting slots 22, and the guide rod 41 is passed through the moving block 46, and the guide rod 41 and the moving block 46 are slidably connected.

[0038] Specifically, by turning on the lifting motor 6, the lifting motor 6 can drive the double-section worm 43 to rotate, thereby ensuring that the double-section worm 43 drives the two second worm wheels 42 to rotate synchronously and at the same speed. The guide rod 41 and the moving block 46 are connected by a sliding connection, so that when the screw 39 rotates and drives the moving block 46 to move, the moving block 46 can slide on the guide rod 41, ensuring the stability and directionality of the moving block 46 during movement.

[0039] Please refer to the attached Figure 9 -Attached Figure 13 The disassembly assembly includes a slide plate 44, a slide bar 47, a mounting rod 50, a second spring 48, a limiting ring 45 and a handle 49.

The two mounting rods 50 are fixedly mounted on one side of the slide plate 44. The two second springs 48 are respectively sleeved on the outer side of the slide bar 47. The two limiting rings 45 are respectively fixedly mounted on one end of the slide bar 47. The handle 49 is fixedly mounted at the center of one side of the slide plate 44. A control panel 35 is installed on one side of the two vertical plates 2. Two slots 51 are provided on the top surface of the disassembly seat 38. Two plug-in blocks 52 are fixedly connected to the bottom surface of the shell 19. Mounting slots 53 are provided on both sides of the two plug-in blocks 52.

When the second spring 48 is squeezed, it can push the slide plate 44 through the reverse force. The diameter of the limiting ring 45 is larger than the diameter of the slide bar 47, thereby preventing the slide plate 44 from detaching from the slide bar 47. The size and size of the slot 51 correspond to the size and size of the plug block 52. The size and size of the mounting rod 50 correspond to the size and size of the mounting slot 53. When the plug block 52 is inserted into the slot 51, the mounting rod 50 can be inserted into the mounting groove 53, so that the plug block 52 can be fixed inside the slot 51, and the housing 19 and the industrial digital camera 54 can be fixedly mounted on the top of the disassembly seat 38. When the industrial digital camera 54 is disassembled for maintenance and debugging, it is only necessary to touch the fixed state of the plug block 52. When the fixed state of the plug block 52 is released, the third spring 55 can push the push plate 30 to move upward through the reverse force, and the push plate 30 can lift the plug block 52 upward, which can facilitate the staff to pull out the housing 19, thereby increasing the convenience of disassembling and assembling the housing 19 and the industrial digital camera 54.
