Description

Technical Field

[0001] The invention relates to the field of electroscope testing, and in particular to a transmission device for electroscope calibration. Background Art

[0002] A tester is usually an instrument used to detect whether an object is charged. Among electrician tools, a tester is a very basic and important tool that can help electricians determine whether there is current passing through wires or equipment. There are many types of testers, including but not limited to: non-contact testers, pen testers (see Figure 1 ) and digital electroscope.

[0003] The pen-type electrometer is generally composed of a metal probe and an insulating handle. The metal probe is usually made of bare metal and is connected to one end of the electrometer to contact the surface of the object to be tested. The insulating handle is provided with components such as a resistor, an LED light and a spring to ensure that when the electrometer contacts a charged object, the LED light will light up to remind the user that the object to be tested is charged. A wrist guard is usually provided on the outside of the insulating handle to prevent the insulating handle from slipping off during use.

[0004] After manufacturing, pen testers usually need to be checked and calibrated for their functions. One of the calibration contents is to contact the pen tester with a charged object to test whether the LED light can light up normally. The following problems exist when calibrating this content: The current way to check whether the LED light of a pen tester is working properly is mostly to manually hold the pen tester in contact with a test power supply, observe whether the LED light is lit normally, and then screen out the pen testers that cannot light up normally and perform further calibration. On the one hand, this calibration method has low calibration efficiency and requires more manpower. On the other hand, since it needs to contact with the test power supply, there are certain safety risks in the calibration process. Summary of the invention

[0012] Preferably, the alignment mechanism includes a U-shaped frame. There are two U-shaped frames arranged left and right, and both U-shaped frames are located on the left side of the C-shaped seat.

[0033] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

[0034] See also Figure 2 A conveying device for calibrating an electroscope, comprising an H-shaped frame, wherein two H-shaped frames are symmetrically arranged on the left and right, and the top ends of the vertical sections of the two H-shaped frames are rotatably connected with a transmission roller 1, and a plurality of conveyor belts 2 are connected to the two transmission rollers 1 for uniform front-back transmission, and adjacent conveyor belts 2 are fixedly connected by a plurality of connecting strips 21 arranged therebetween, and a plurality of through grooves 22 are uniformly opened on the conveyor belt 2 along its length direction, and a positioning seat 23 is fixedly connected to the outer surface of the conveyor belt 2 and located between the two through grooves 22, and the end surface of the positioning seat 23 away from the conveyor belt 2 is opened with a V-shaped groove.

[0035] See also Figure 2 and Figure 3 A driving mechanism 3 is connected to the right side of the left H-shaped frame, and the driving mechanism 3 includes a U-shaped support 31, and the U-shaped support 31 opens downward. A rotating shaft 32 passes through and is rotatably connected to the horizontal section of the U-shaped support 31. A fixed sleeve on the upper end of the rotating shaft 32 is provided with a disk 33 that matches the positioning seat 23, and a fan-shaped notch 34 is opened on the disk 33. A lever 35 is fixedly provided at the upper end of the rotating shaft 32 and located below the disk 33. The lever 35 is located on the right side of the fan-shaped notch 34, and a driving motor 36 is fixedly connected to the lower end of the rotating shaft 32.

[0036] During specific operation, the driving motor 36 runs, driving the lever 35 and the disc 33 to rotate counterclockwise synchronously. The lever 35 rotates counterclockwise and periodically contacts the positioning seat 23 below. At this time, due to the presence of the fan-shaped notch 34 on the disc 33, the disc 33 does not contact the positioning seat 23. After the lever 35 contacts the positioning seat 23, it pushes it to move a distance to the left. In this process, the leftmost conveyor belt 2 also feeds the same distance counterclockwise synchronously, and the remaining conveyor belts 2 also feed the same distance synchronously under the drive of the connecting strip 21. The feeding distance is the same as the spacing between two adjacent positioning seats 23. The lever 35 disengages from the positioning seat 23 after rotating a certain angle. At this time, the disc 33 also rotates between the last two positioning seats 23, thereby preventing the positioning seat 23 from continuing to move to the left under inertia. At this time, the conveyor belt 2 is also in a stationary state, and the above method is used to make each conveyor belt 2 intermittently feed the same spacing.

[0037] In the gap when the conveyor belt 2 is stationary, the staff will place the tester 9 to be tested on two adjacent positioning seats 23 at the right end of the conveyor belt 2 in turn. Since the surface of the tester 9 is circular, it will roll to the bottom along the V-shaped groove, and then each tester 9 is located in the middle position of each conveyor belt 2. After that, when the conveyor belt 2 intermittently feeds to the left, it will drive the tester 9 to move synchronously to the left.

[0038] See also Figure 2 Two mounting plates 4 are symmetrically and rotatably connected to the roller shafts of the two driving rollers 1. A direction detection mechanism 5 for detecting the placement direction of the electroscope 9 is connected to the two mounting plates 4. A reversing mechanism 6 for converting the direction of the electroscope 9 is provided on the outer sides of the plurality of conveyor belts 2. A positioning mechanism 7 for aligning the left and right ends of the electroscope 9 is connected to the two mounting plates 4. The positioning mechanism 7 is located on the left side of the reversing mechanism 6. A testing mechanism 8 is connected to the upper end surfaces of the two mounting plates 4 and on the left side of the positioning mechanism 7.

[0039] See also Figure 2 , Figure 4 and Figure 5 The direction detection mechanism 5 includes a U-shaped plate 51, and two U-shaped plates 51 are symmetrically fixedly connected to the two mounting plates 4. The U-shaped plate 51 opens downward, and a plurality of rectangular plate groups 52 corresponding to the conveyor belt 2 are evenly fixedly connected to the front and rear of the lower end of the horizontal section of the U-shaped plate 51. The rectangular plate group 52 includes two rectangular plates symmetrically front and back, and a baffle 53 for preventing the electroscope 9 from falling is fixedly connected to the lower ends of the two corresponding rectangular plates on the left and right. A distance sensor 54 is fixedly connected to the baffle 53 below each rectangular plate group 52 and on the front side, and the distance sensor 54 is located on the front side of the baffle 53.

[0040] For specific work, see Figure 1 Since the diameters of the metal probe 91, the insulating handle 92 and the hand ring 93 of the electroscope 9 are greatly different, the reading of the electroscope 9 will change when it moves to the left and passes the distance sensor 54. Assuming that the straight-line distances between the distance sensor 54 and the metal probe 91, the insulating handle 92 and the hand ring 93 are set to a, b, and c respectively (see Figure 5 ), during the process of the conveyor belt 2 and the positioning seat 23 transporting the electroscope 9 to the left and passing through the distance sensor 54, if the indication of the distance sensor 54 during the passage of the electroscope 9 changes from a to b, b to c, and then to b, it means that the metal probe 91 of the electroscope 9 points to the left, and the electroscope 9 is pointing correctly here; and when the indication of the distance sensor 54 during the passage of the electroscope 9 changes from b to c, c to b, and b to a, it means that the metal probe 91 points to the right, and the electroscope 9 is pointing in the wrong direction here. When the electroscope 9 with the wrong direction moves to the bottom of the corresponding reversing mechanism 6 along with the conveyor belt 2 and the positioning seat 23, the reversing mechanism 6 operates to adjust the direction of the electroscope 9.

[0041] See also Figure 3, the commutation mechanism 6 includes a U-shaped support 61 with its opening facing downward. The two vertical sections of the U-shaped support 61 are symmetrically arranged on both sides of the two mounting plates 4 in the front and back. The horizontal section of the U-shaped support 61 is located above the conveyor belt 2. A cross plate 62 is fixedly connected between the two vertical sections of the U-shaped support 61. A plurality of first cylinders 63 corresponding to the conveyor belt 2 are evenly and fixedly connected to the lower end of the cross plate 62 in the front and back. The piston rod of the first cylinder 63 faces upward and is connected to a commutation component 64.

[0042] During specific operation, when the electroscope 9 with incorrect indication moves to below the rotating plate 645 along with the conveyor belt 2 and the positioning seat 23 and stops, the piston rod of the corresponding first cylinder 63 located below the electroscope 9 extends, driving the entire commutation component 64 to move upward. Since the feeding distance of the conveyor belt 2 per single time is the same, when the conveyor belt 2 stops, there are always two through slots 22 above the first cylinder 63 that are on the same axis as the piston rod of the first cylinder 63. Therefore, the piston rod of the first cylinder 63 can pass through the through slots 22 and lift the electroscope 9 with incorrect indication upward through the commutation component 64.

[0043] Refer to Figure 6 and Figure 7 , the commutation component 64 includes a cylinder 641 with an opening on its upper surface. The lower end of the cylinder 641 is fixedly connected to the piston rod of the first cylinder 63. A rotating module 642 is connected inside the opening of the cylinder 641. The upper end of the rotating module 642 is connected to a cylindrical seat 643 corresponding to and cooperating with the through slots 22. A placement groove 644 matching the electroscope 9 is provided on the upper end surface of the cylindrical seat 643. A rotating plate 645 cooperating with the cylindrical seat 643 is rotatably connected to the horizontal section of the U-shaped support 61.

[0044] Refer to Figure 6 and Figure 7 , the rotating module 642 includes a cylindrical cam 6421. The upper end of the cylindrical cam 6421 is fixedly connected to the lower end of the cylindrical seat 643. The cylindrical cam 6421 is connected to the inside of the cylinder 641 through damping, and the cylindrical cam 6421 and the cylinder 641 can rotate relative to each other and slide up and down relative to each other. A corrugated groove 6422 is provided on the surface of the cylindrical cam 6421. A spring type universal ball 6423 is fixedly connected to the outer wall of the cylinder 641. The spring type universal ball 6423 is slidably connected in the corrugated groove 6422. The corrugated groove 6422 includes two inclined sections and two vertical sections, and the inclined sections and the vertical sections are arranged alternately and communicate with each other (refer to Fig.11), the depth of the inclined section gradually increases from bottom to top, the depth of the lowest point of the inclined section is less than the depth of the lowest point of the vertical section, and the depth of the highest point of the inclined section is greater than the depth of the highest point of the vertical section, so as to ensure that the spring-type universal ball 6423 always slides along the same path, and the lower end rotating sleeve of the cylindrical cam 6421 is provided with an annular sleeve 6424, and the annular sleeve 6424 is fixedly connected to the cylinder 641 by a pressure spring 6425.

[0045] During specific operation, in the initial state, the spring-loaded universal ball 6423 is located at the bottom of one of the straight sections of the corrugated groove 6422. When the piston rod of the No. 1 cylinder 63 moves upward, it drives the cylinder 641 upward, and then drives the cylindrical cam 6421 and the cylindrical seat 643 to move upward synchronously through the pressure spring 6425 and the annular sleeve 6424. When the cylindrical seat 643 moves upward, it will pass through the through groove 22 and lift the electroscope 9 to move upward. In this process, since the common gravity of the electroscope 9, the cylindrical seat 643, the annular sleeve 6424 and the cylindrical cam 6421 is less than the elastic force of the pressure spring 6425, the pressure spring 6425 always maintains the same degree of compression.

[0046] Until the top of the cylindrical seat 643 abuts against the rotating plate 645, as the piston rod of the No. 1 cylinder 63 continues to rise, the pressure spring 6425 is further compressed, and the spring-type universal ball 6423 slides upward along the inclined section of the corrugated groove 6422, driving the cylindrical cam 6421 and the cylindrical seat 643 to slide downward relative to the cylinder 641. At the same time, the cylindrical cam 6421 and the cylindrical seat 643 will also carry the electroscope 9 to rotate counterclockwise by 180 degrees synchronously on the left and right of the corrugated groove 6422 and the spring-type universal ball 6423. At this time, the rotating plate 645 rotates synchronously with the cylindrical seat 643.

[0047] When the spring-loaded universal ball 6423 slides to the top of the inclined section of the corrugated groove 6422, the piston rod of the No. 1 cylinder 63 descends. At this time, under the elastic force of the pressure spring 6425, the top of the cylindrical seat 643 is still in contact with the rotating plate 645, while the cylindrical cam 6421 and the cylindrical seat 643 slide downward compared to the cylinder 641, and then the spring-loaded universal ball 6423 enters the vertical section of the corrugated groove 6422 and slides downward along it. As the piston rod of the No. 1 cylinder 63 continues to descend, it drives the cylindrical seat 643 to move below the conveyor belt 2, and the reversing tester 9 is placed on the positioning seat 23 again.

[0048] See also Figure 2 and Figure 8, the alignment mechanism 7 includes U-shaped frames 71. There are two U-shaped frames 71 arranged left and right, and both of the two U-shaped frames 71 are located on the left side of the C-shaped support 61. The U-shaped frames 71 have their openings facing downward, and their two vertical segments are fixedly connected to the two mounting plates 4. Lifting rods 72 are slidably inserted through the horizontal segments of the two U-shaped frames 71. The upper ends of the lifting rods 72 are fixedly connected together with a connecting plate 73. An external cylinder for driving the connecting plate 73 to move up and down is connected to the upper end of the connecting plate 73. The lower end of the right lifting rod 72 is connected to an alignment component 74. The function of the alignment component 74 is to align the left and right ends of each electroscope 9 that moves below it. The lower end of the left lifting rod 72 is connected to a pushing component 75. The pushing component 75 is used to push the electroscope 9 with its left and right ends aligned into contact with the testing mechanism 8.

[0049] Refer to Figure 8 , the alignment component 74 includes a connecting seat 741. Hinge frames 742 are symmetrically rotatably connected to the left and right sides of the connecting seat 741. The end of the hinge frame 742 far from the connecting seat 741 is connected to a reset module 743. The end of the reset module 743 far from the connecting seat 741 is connected to a T-shaped plate 744. On the mounting plate 4 and symmetrically slidably connected to the left and right sides of the right U-shaped frame 71 are sliding seats 745. The upper end surfaces of the sliding seats 745 are fixedly connected to vertical rods 746. The two ends of the horizontal segment of the T-shaped plate 744 are slidably connected up and down to two corresponding vertical rods 746 in the front and back. A plurality of push plates 747 corresponding to the conveyor belt 2 are evenly fixedly connected to the lower end of the horizontal segment of the T-shaped plate 744.

[0050] Refer to Figure 2 , Figure 8 and Fig. 9 , the reset module 743 includes a round rod 7431. The end of the hinge frame 742 far from the connecting seat 741 is fixedly connected to a round rod 7431 extending in the front and back direction. A hinge seat 7432 that cooperates with the hinge frame 742 is rotatably connected to the round rod 7431. Round plates 7433 are fixedly connected to both ends of the round rod 7431. The round plates 7433 are fixedly connected to the hinge seat 7432 through torsion springs 7434. The end of the hinge seat 7432 far from the connecting seat 741 is fixedly connected to the T-shaped plate 744.

[0051] When the lifting rod 72 is lowered, the connecting seat 741 and the hinged plate 742 are in a horizontal state, and the two ends of the T-shaped plate 744 slide downward along the vertical rod 746. When the T-shaped plate 744 drops to a certain height and its lower end abuts against the baffle 53, the height of the vertical section of the T-shaped plate 744 remains unchanged. As the lifting rod 72 continues to descend, the upward angle between the two hinged frames 742 will be reduced, thereby reducing the distance between the ends of the two hinged frames 742 that are far away from each other. The two T-shaped plates 744 move in the same direction, and then the left and right ends of the electroscope 9 are aligned through the push plate 747.

[0052] See also Figure 8 and Fig.10 The pushing assembly 75 includes a rectangular seat 751, the lower end of which is connected to a hinged plate 752 through a reset module 743. The hinged plate 752 is inclined to the left, and the lower end of the hinged plate 752 is rotatably connected to a long plate 753. The lower end surface of the long plate 753 is fixedly connected to a plurality of half rings 754 corresponding to the conveyor belt 2, and the inner surface of the half ring 754 is rollingly embedded with balls.

[0053] See also Figure 8 The testing mechanism 8 includes a U-shaped frame 81, which opens downward and is arranged on the left side of the left U-shaped frame 71. The two vertical sections of the U-shaped frame 81 are fixedly connected to the two mounting plates 4. The upper end surface of the horizontal section of the U-shaped frame 81 is fixedly connected to a No. 2 cylinder 82. The piston rod of the No. 2 cylinder 82 is downward and fixedly connected to a connecting plate 83. The lower end surface of the connecting plate 83 is evenly and fixedly connected to a plurality of test power supplies 84 that match the electroscope 9.

[0054] During specific operation, in the process of aligning the two ends of the rear group of electroscopes 9 by the push plate 747, the front group of electroscopes 9 is also located below the left U-shaped frame 71 and remains stationary. At this time, when the external cylinder drives the connecting plate 73 to descend, it will also drive the left lifting rod 72 to descend synchronously. The descent of the left lifting rod 72 drives the hinge seat 7432, the hinge plate 752, the long plate 753 and the semi-ring 754 to descend synchronously. After the semi-ring 754 descends to a certain height, the semi-ring 754 at its lower end will abut against the insulating handle 92. Since the hinge plate 752 is deflected to the left in the initial state, as the subsequent hinge seat 7432 continues to descend, the deflection angle of the hinge plate 752 to the left will increase, thereby pushing the hand guard ring 93 to move the electroscope 9 to the left.

[0055] Initially, the piston rod of the No. 2 cylinder 82 is in an extended state, and the connecting plate 83 and the test power supply 84 are at the bottom. Then, when the electroscope 9 moves to the left, the metal probe 91 at its left end will contact the test power supply 84. At this time, if the LED light on the electroscope 9 is displayed normally, it means that the electroscope 9 is normal and no calibration is required. If the LED light on the electroscope 9 does not light up, it means that the electroscope 9 is faulty, and the staff will pick it out from the conveyor belt 2 and calibrate it later. After a group of electroscopes 9 are tested, the piston rod of the No. 2 cylinder 82 contracts, driving the connecting plate 83 and the test power supply 84 to move upward synchronously. After that, the electroscope 9 can move with the conveyor belt 2 and the positioning seat 23, pass under the test power supply 84, and fall into the external collection device located on the left side of the conveyor belt 2.

[0056] Working principle: S1: The driving mechanism 3 drives the conveyor belt 2 to feed intermittently from right to left through the positioning seat 23. The staff on the right side of the conveyor belt 2 places the electroscope 9 on the positioning seat 23 from the left side, and the conveyor belt 2 and the positioning seat 23 transport the electroscope 9 to move intermittently to the left.

[0057] S2: When the electroscope 9 moves to the left, when passing through the direction detection mechanism 5, the direction detection mechanism 5 detects the direction of the electroscope 9 through the distance sensor 54. After that, when the electroscope 9 continues to move to the left to the position of the reversing mechanism 6, the reversing mechanism 6 reverses the electroscope 9 that is pointing in the wrong direction.

[0058] S3: When the electrometer 9 continues to move to the left to the position of the alignment mechanism 7, the positioning component 74 in the alignment mechanism 7 first aligns the left and right ends of the corresponding electrometers 9 on the multiple conveyor belts 2. Then, when the electrometer 9 with the front and rear ends aligned moves to the position of the pushing component 75, the pushing component 75 pushes it to the left for a distance, so that the electrometer 9 contacts the test power supply 84. Finally, the staff on the right selects the electrometer 9 whose LED light does not display for debugging and calibration.
