Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] The sensor of the vacuum circuit breaker in the present invention is a type of power electronic component in the smart grid industry. Before the sensor is installed on the vacuum circuit breaker, the sensor needs to be assembled on a sliding platform and sent into the assembly equipment for automated assembly and testing procedures. It is a type of industrial robot in the smart manufacturing equipment industry.

[0042] Example 1

[0043] Refer to the instruction manual Figure 1A sensor assembly device for a vacuum circuit breaker according to an embodiment of the present invention comprises a base 1 and a vacuum box 2 located on the base 1, an electric lifting door 3 is installed on one side of the vacuum box 2, an industrial display 4 is fixedly installed on the base 1, and a guiding and pushing mechanism 5 for pushing a sensor to be detected into and out of the vacuum box 2 is provided on the top of the base 1;

[0044] A supporting plate 10 for placing the sensor to be detected is fixedly installed at the pushing end of the guiding pushing mechanism 5, and a clamping positioning mechanism 6 for automatically clamping and positioning the sensor to be detected is provided on the top of the supporting plate 10, and a correction and reset mechanism 8 for correcting the excessive deviation of the sensor to be detected is provided at one end of the clamping positioning mechanism 6 close to the supporting plate 10.

[0045] It should be noted that the present invention places the sensor to be tested on the top of the carrier plate 10, and then uses the correction and reset mechanism 8 to assist the clamping and positioning mechanism 6 to accurately position and clamp the target sensor. Then, the carrier plate 10 is pulled into the vacuum box 2 by guiding the pushing mechanism 5, the electric lifting door 3 is closed, and the interior of the vacuum box 2 is evacuated into a vacuum state, and the target sensor is automatically assembled and tested by an industrial robot.

[0046] Specifically, Figure 1-3 As shown, the guiding and pushing mechanism 5 includes two groups of L-shaped guide frames 51 fixedly installed on the top of the base 1 and located on the inner and outer sides of the vacuum box 2, with two in each group, and a lifting seat 53 is fixedly provided between the two L-shaped guide frames 51 in each group, and an electric push rod 52 is fixedly installed at the position between the two L-shaped guide frames 51 located on the inner side of the vacuum box 2 on the top of the base 1, and the telescopic end of the electric push rod 52 is fixedly connected to the sliding platform 9, wherein the setting of the lifting seat 53 can assist in supporting the sliding platform 9, thereby reducing the direct pressure of the sliding platform 9 on the guide part on the L-shaped guide frame 51 during the movement, and a rolling assembly is provided between the sliding platform 9 and the L-shaped guide frame 51;

[0047] The rolling assembly includes straight grooves 56 opened on both sides of the sliding platform 9 and a lifting roller seat 55 fixed on the top of the base 1 and located between the two groups of L-shaped guide frames 51, wherein a roller is rotatably installed on the top of the lifting roller seat 55, which is used to convert the sliding friction between the sliding platform 9 and the lifting roller seat 55 into rolling friction, and support the sliding platform 9 that reciprocates between the two groups of L-shaped guide frames 51, each straight groove 56 is rotatably installed with a roller plate 57, and each L-shaped guide frame 51 is rotatably installed with a roller column 54 on the inner side, wherein the setting of the roller column 54 and the roller plate 57 can convert the sliding friction force of the direct contact between the sliding platform 9 and the L-shaped guide frame 51 into rolling friction, thereby reducing energy consumption, and a limiting groove 58 is opened at the bottom of the sliding platform 9 corresponding to the position of the lifting seat 53, wherein the setting of the limiting groove 58 can guide and limit the lifting seat 53 to ensure the stability of the sliding platform 9 during movement.

[0048] It should be noted that when the guiding and pushing mechanism 5 is used to drive the sliding platform 9 to switch back and forth between the inspection station located inside the vacuum box 2 and the loading and unloading station located outside the vacuum box 2, the sliding platform 9 is directly pushed in and out of the vacuum box 2 by the electric push rod 52, and in the process of pushing the sliding platform 9 to move, the roller rotatably installed on the top of the lifting roller seat 55, the roller plate 57 rotatably installed inside the straight groove 56 on both sides of the sliding platform 9, and the roller column 54 rotatably installed on the inner side of the L-shaped guide frame 51 are used to convert the sliding friction between the sliding platform 9 and the lifting roller seat 55 and the L-shaped guide frame 51 into rolling friction, which can not only reduce energy consumption, but also reduce the noise generated by the sliding platform 9 during movement.

[0049] Specifically, Figure 2-4 As shown, the clamping and positioning mechanism 6 includes a square ring tube 61 fixedly installed at the center position of the top of the carrying plate 10 and a rotating rod 65 rotatably installed inside the square ring tube 61. The carrying plate 10 is fixedly installed on the top of the sliding platform 9, so that the carrying plate 10 and the sliding platform 9 maintain a synchronous movement state, so that the installed target workpiece can be accurately switched between the detection station located inside the vacuum box 2 and the loading and unloading station located outside the vacuum box 2. Corner grooves 63 are provided at the four corners of the top of the square ring tube 61, and a square plate 64 is fixedly provided on the top surface of the square ring tube 61, wherein the square plate 64 is fixedly connected to the part of the top of the square ring tube 61 located between two adjacent corner grooves 63 through a locking bolt, a strip groove 62 is provided at the bottom end of the square ring tube 61, a servo motor 1 is fixedly installed on the top of the square plate 64, and the output shaft end of the servo motor 1 is fixedly connected to the rotating rod 65, and the outer ends of the rotating rod 65 are provided with threads arranged in opposite directions, and a position adjustment component and a clamping component are respectively installed at both ends of the rotating rod 65.

[0050] It should be noted that, when the sensor to be detected is placed on the top of the carrier plate 10 (the sensor structure is as shown in FIG. Fig.12 When clamping and fixing, the servo motor is started by the control end to drive the rotating rod 65 to rotate, and the threads arranged in opposite directions at the two ends of the outer side of the rotating rod 65 are used to drive the adjustment component and the clamping component to move toward / away from each other, so as to realize automatic clamping and positioning of the target sensor and release the automatic clamping and positioning state.

[0051] Specifically, Figure 3-4 and Figure 7As shown, the position adjustment component includes an I-shaped plate 69 that is inserted into the strip groove 62, and the I-shaped plate 69 is threadedly sleeved on the bottom end of the rotating rod 65. Blocks 610 that fit the outer side of the square ring tube 61 are fixedly provided on both sides of the I-shaped plate 69. The block 610 can be used to assist in limiting the position of the I-shaped plate 69, so that it can stably move up and down under the drive of the threaded section at the corresponding end of the rotating rod 65. Adjustment brackets 611 are fixedly provided at both ends of the top of the I-shaped plate 69, wherein the top of the adjustment bracket 611 is set as a concave structure, which can be used to drag the target sensor. When adjusting the position, the lifted part of the target sensor automatically approaches the middle of the arc section of the deflection adjustment bracket 611 for deflection adjustment. A groove 612 is provided on the top of the deflection adjustment bracket 611. A second roller 613 is rotatably installed inside the groove 612. The diameter of the second roller 613 is greater than the depth of the groove 612. When the deflection adjustment bracket 611 lifts the target sensor for deflection adjustment, the second rotatably installed roller 613 is in direct contact with the target sensor, thereby reducing the friction force on the lifted part of the target sensor during deflection correction.

[0052] The deflection correction and reset mechanism 8 includes a protrusion 81 fixed on the top of the carrier plate 10 and a cylinder 82 fixed on the outside of the deflection adjustment bracket 611. A deflection arc plate 83 is rotatably mounted on the outside of the cylinder 82. A spring 1 84 is fixedly connected between the corresponding protrusion 81 and the deflection arc plate 83. When the spring 1 84 is in a natural state, the initial state of the deflection arc plate 83 is as follows: Figure 7 As shown, the deflection arc plate 83 will not be dislocated from the cylinder 82 during the deflection process with the cylinder 82 as the center.

[0053] It should be noted that when the adjustment assembly is used to adjust the position of the target sensor placed on the top of the carrier plate 10, as the rotating rod 65 rotates, the I-shaped plate 69 will move upward along the strip groove 62. In this process, since the spring 1 84 is fixedly connected between the protrusion 81 and the low end of the deflection arc plate 83, when the I-shaped plate 69 moves upward under the drive of the rotating rod 65, the spring 1 84 will be stretched, so that the low end of the deflection arc plate 83 will deflect downward with the cylinder 82 as the center, and then the high end of the deflection arc plate 83 that deflects upward is used to move the upper end of the target sensor. The lifted portion that deviates from the arc area on the deflection adjustment support 611 approaches the arc area on the deflection adjustment support 611, so as to prevent the end of the target sensor that deviates from the arc area on the deflection adjustment support 611 from directly contacting and being damaged by the deflection adjustment support 611 when it rises. After the lifted portion on the target sensor enters the corresponding arc area on the deflection adjustment support 611, as the I-plate 69 continues to rise, the lifted portion on the target sensor directly contacts the roller 2 613 on the deflection adjustment support 611, and gradually approaches the middle position along the arc surface on the deflection adjustment support 611, thereby automatically completing the deflection adjustment action.

[0054] Specifically, Figure 3-6 As shown, the clamping assembly includes a lifting plate 66 threadedly sleeved on the top of the rotating rod 65, and a trapezoidal groove 68 is provided at the top of the lifting plate 66 between two adjacent corner grooves 63, wherein the setting of the trapezoidal groove 68 can not only ensure the vertical movement of the lifting plate 66 along the square ring tube 61, but also use the trapezoidal groove 68 to limit the part between the two adjacent corner grooves 63 at the corresponding position, and the part of the top of the square ring tube 61 between the two adjacent corner grooves 63 is movably inserted into the corresponding trapezoidal groove 68, and strips 67 are fixed at the four corners of the outer side of the lifting plate 66, wherein the setting of the strips 67 can facilitate the lifting plate 66 to be sleeved on the top of the square ring tube 61, and assist in pressing the top surface of the target sensor to avoid local warping.

[0055] It should be noted that when the clamping assembly is used to clamp and limit the target sensor placed on the top of the carrier plate 10, as the rotating rod 65 rotates, the lifting plate 66 will move downward along the angle groove 63. During this process, the downward movement of the lifting plate 66 and the upward movement of the I-plate 69 are performed synchronously, which can ensure that while completing the position correction of the offset target sensor, the target sensor is clamped and limited, and ensure that the positioning hole on the lifting plate 66 is aligned with the locking hole at the top of the target sensor.

[0056] Example 2

[0057] Refer to the instruction manual Figure 5-6 and Figure 8 , a sensor assembly device for a vacuum circuit breaker according to an embodiment of the present invention, the clamping positioning mechanism 6 is provided with a locking screw mechanism 7 for limiting the position of the sensor to be detected at one end away from the bearing plate 10, the locking screw mechanism 7 includes screw holes opened at the four corners of the top of the lifting plate 66 and an F-type bracket 71 fixed on the top of each strip plate 67, a circular plate 72 and a circular ring 73 are fixedly connected to the outside of the F-type bracket 71, a limiting column 74 is fixedly provided at the position corresponding to the screw hole at the bottom of the circular plate 72, a limiting ring 75 is fixedly provided at the position corresponding to the screw hole at the top of the circular ring 73, a bolt barrel 76 is rotatably installed between the limiting column 74 and the limiting ring 75, wherein the limiting column 74 is inscribed in the inside of the bolt barrel 76, the inner diameter of the limiting ring 75 is equal to the outer diameter of the bolt barrel 76, and the bolt barrel 76 can be limited without affecting the rotation of the bolt barrel 76;

[0058] A bolt 79 is arranged inside the bolt barrel 76, wherein the inner diameter of the ring 73 is smaller than the maximum radial length of the bolt head of the bolt 79 and larger than the maximum outer diameter of the bolt rod of the bolt 79, so as to ensure that the bolt 79 does not separate from the bolt barrel 76 and does not affect the rotation of the bolt 79, and the bottom end of the bolt rod of the bolt 79 is threadedly connected to the inside of the screw hole on the lifting plate 66;

[0059] A secondary gear ring 77 is fixedly sleeved on the outside of each bolt tube 76, and a support plate 78 is fixedly provided at the bottom of the secondary gear ring 77. A main gear ring 710 that meshes with the four secondary gear rings 77 is provided between the top surfaces of the four support plates 78, wherein the four support plates 78 can be used to support the main gear ring 710 to prevent the main gear ring 710 from being dislocated from the secondary gear ring 77 and failing to drive and tighten the bolts 79. A tooth groove 711 is provided on the inner side of the main gear ring 710, and a servo motor 2 is fixedly installed on the top of the lifting plate 66, and a gear 712 that meshes with the tooth groove 711 is fixedly connected to the end of the output shaft of the servo motor 2.

[0060] It should be noted that when the top of the target sensor that has completed the clamping and positioning is screwed and fixed, the control end controls the servo motor 2 to drive the gear 712 to rotate, and the rotating gear 712 is used to drive the main gear ring 710 to rotate. The rotating main gear ring 710 will simultaneously drive the four auxiliary gear rings 77 to rotate, thereby driving the bolt barrel 76 to rotate, and then the rotating bolt barrel 76 is used to drive the bolt 79 to rotate. Since the bottom end of the bolt rod part of the bolt 79 is threadedly connected to the inside of the screw hole on the lifting plate 66, when the bolt 79 is driven to rotate, the bolt rod part of the bolt 79 will pass through the screw hole and enter the locking hole at the top of the target sensor at the corresponding position, thereby completing the locking and positioning of the target sensor.

[0062] Refer to the instruction manual Figure 2 , Fig. 9 and Fig.11 , a sensor assembly device for a vacuum circuit breaker according to an embodiment of the present invention, wherein the top of the carrier plate 10 is provided with four limiting holes 11 evenly distributed in a ring shape with the center of the square ring tube 61, wherein the setting of the limiting holes 11 can pre-limit the target sensor installed on the carrier plate 10, and the carrier plate 10 is further provided with positioning holes 12 distributed outside each limiting hole 11, and each limiting hole 11 is provided with an end protection mechanism 13, wherein three end protection mechanisms 13 are provided in each limiting hole 11 and are evenly distributed in a ring shape;

[0063] A protective gasket 14 is provided at the position corresponding to each limiting hole 11 on the top of the carrier plate 10, and a through hole 15 and a clamping column 16 are respectively provided at the position corresponding to the limiting hole 11 and the locking hole 12 on the top of the protective gasket 14. The clamping column 16 is movably inserted into the locking hole 12. The structural design of inserting the clamping column 16 into the locking hole 12 can effectively prevent the installed protective gasket 14 from shifting during the installation of the target sensor, which can not only avoid frequent adjustment of the position of the protective gasket 14, but also shorten the time for installing the target sensor.

[0064] It should be noted that, in the process of installing the target sensor on the carrier plate 10, the protective gasket 14 is first inserted on the top of the carrier plate 10, so that the through hole 15 is aligned with the limit hole 11 on the carrier plate 10, and then the bottom of the target sensor (refer to Fig.12 The end head in the state shown in the figure is inserted into the limiting hole 11, and the end head protection mechanism 13 inside the limiting hole 11 is used to protect the end head inserted into the limiting hole 11 to avoid damage to the inserted end head during the installation process.

[0065] Specifically, Figure 9-10 As shown, the end protection mechanism 13 includes a seat block 131 and an arc-shaped clamping plate 138 arranged inside the limiting hole 11, the seat block 131 is fixed on the inner side of the limiting hole 11, two ear plates 139 are fixedly provided on the middle part of the outer side of the arc-shaped clamping plate 138, the top and bottom of the seat block 131 are fixedly provided with fixed blocks 132, and both sides of the seat block 131 are fixedly provided with convex columns 133, the two convex columns 133 are rotatably installed between the ear plates 139 on the sides respectively, and elastic reset components are provided between the two fixed blocks 132 and the arc-shaped clamping plate 138, wherein the rotational installation between the convex columns 133 and the ear plates 139 can make the arc-shaped clamping plate 138 deflect, and the upper and lower sets of elastic reset components are used to limit the deflection amplitude of the arc-shaped clamping plate 138;

[0066] The elastic reset assembly includes a sleeve 134 fixed on the outside of the fixed block 132, a sleeve rod 135 movably inserted inside the sleeve 134, a spring 2 136 is fixedly connected between one end of the sleeve rod 135 extending to the inside of the sleeve 134 and the inner side of the sleeve 134, and a T-shaped push block 137 is hingedly installed on one end of the sleeve rod 135 extending to the outside of the sleeve 134, wherein when the spring 2 136 is in a natural state, the two T-shaped push blocks 137 just push the arc-shaped clamping plate 138 to a horizontal state, and during the elastic deformation of the spring 2 136, the end of the sleeve rod 135 located inside the sleeve 134 never separates from the sleeve 134.

[0067] It should be noted that after the end of the bottom of the target sensor is inserted into the limiting hole 11, since the center of gravity of the target sensor is not on the axis of the limiting hole 11, the non-inserted end of the target sensor will tilt to one side, thereby causing the end of the bottom of the target sensor to tilt. At this time, since three end protection mechanisms 13 are provided inside each limiting hole 11, when the end inserted into the limiting hole 11 tilts, the arc-shaped clamping plate 138 will be squeezed in the tilting direction, causing the arc-shaped clamping plate 138 to deflect in the tilting direction of the end, and push the T-shaped push block 137 in position to compress the corresponding spring 2 136, so that the restoring force generated when the spring 2 136 is compressed can be used to support the tilted end, so as to limit the tilting amplitude of the inserted end and avoid the inserted end directly contacting the inner wall of the corresponding limiting hole 11 and causing damage.

[0068] In summary, the electric push rod 52 mentioned in the above solution adopts an electric push rod of model HB-DJ801; the servo motor 1 and the servo motor 2 both adopt servo motors of model JSMA-PUC02D.

[0069] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
