Description

Technical Field

[0001] This invention relates to the field of calibration and conveying technology, and in particular to a multi-specification attitude calibration and conveying system and method for current transformers. Background Technology

[0002] Current transformers are core components for metering, protection, and monitoring in power systems. Before leaving the factory, they undergo automated testing, sorting, and assembly processes. A neat and uniform conveying posture is a prerequisite for ensuring the accurate operation of automated equipment. Existing current transformer conveying equipment has a fixed channel structure, only suitable for conveying single-specification products. It cannot accommodate the production needs of conveying large-specification single units centrally or small-specification dual units in parallel. The equipment has poor versatility, is cumbersome to change and debug, and is difficult to adapt to mixed-line production conditions of multiple current transformer specifications. Furthermore, traditional correction conveying structures often use rigid clamps or fixed limit guides, resulting in strong clamping rigidity that easily damages the transformer casing. They also lack self-correcting capabilities; when products exhibit posture misalignment or localized protrusions, automatic correction is impossible, requiring manual re-alignment, leading to low automation.

[0003] To address the above problems, this invention proposes a multi-specification attitude correction and transmission system and method for current transformers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing current transformer conveying equipment, which has a fixed channel structure, can only adapt to the conveying of products of a single specification, and cannot meet the production needs of conveying large single-piece products in the center and small double-piece products in parallel. At the same time, traditional correction conveying structures mostly use rigid clamping plates or fixed limiting and guiding methods, which have strong clamping rigidity and are very easy to squeeze and damage the transformer shell. They also lack adaptive correction capabilities. When the product has posture distortion or local bulge deviation, it cannot be automatically corrected and can only be manually corrected again, resulting in low automation. Therefore, this invention proposes a multi-specification posture correction conveying system and method for current transformers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multi-specification attitude correction and conveying system for current transformers includes a conveying device, on which a correction mechanism is provided; The correction mechanism includes a drive assembly, an adjustment assembly, and four elastic support assemblies. Elastic guide assemblies are provided at both ends of the drive assembly and on the corresponding sides of the two elastic support assemblies. The elastic support assemblies support the two inner elastic guide assemblies and also switch the channels of current transformers of different sizes. The adjustment assembly adjusts the travel of the outer elastic guide assemblies. The two inner elastic guide assemblies are arranged opposite to the two outer elastic guide assemblies to correct the attitude of the current transformer.

[0006] Preferably, the drive assembly includes four fixed seats and two bidirectional screws. The two bidirectional screws are connected by a belt drive structure. The bidirectional screws are rotatably mounted on the two fixed seats by two bearings. The fixed seats are fixedly connected to the conveying equipment. One of the bidirectional screws is fixedly connected to the output shaft of the motor. The motor is mounted on the fixed seat. Each of the two fixed seats has a first contact fixedly connected to it.

[0007] Preferably, the bidirectional screw has four threaded sections, with adjacent threaded sections having opposite directions. The bidirectional screw is threaded with two first nuts and two second nuts. The first nuts have positioning openings, and the second nuts are fitted with movable seats. Contact switches are installed on the upper sides of the movable seats. The two movable seats are slidably connected to the slide rod, and the two ends of the slide rod are fixedly connected to two fixed seats.

[0008] Preferably, the adjusting assembly includes a bidirectional lead screw, one end of which is provided with a handle. The bidirectional lead screw is rotatably mounted on a fixed base via two bearings, and the two threaded sections on the bidirectional lead screw are arranged in opposite directions.

[0009] Preferably, the bidirectional lead screw is threaded with two adjusting nuts, and adjusting seats are installed on the adjusting nuts. The two adjusting seats are slidably connected to the slide rod, and a second contact is fixedly connected to one side of the adjusting seat.

[0010] Preferably, the elastic support assembly includes a telescopic rod and a first spring. The two ends of the telescopic rod and the first spring are respectively fixedly connected to two connecting members. Both connecting members are hinged to a hinge member and a connecting seat respectively through pins. A side plate is fixedly connected to one side of the hinge member, wherein a toothed rod is fixedly connected to one side of each of the two diagonally opposite side plates and one side of each of the two diagonally opposite movable seats.

[0011] Preferably, a locking sleeve is installed on the connecting seat, and a locking rod is slidably connected in the locking sleeve. One end of the locking rod is engaged in the positioning hole, and a second spring is fixedly connected between the other end of the locking rod and the locking sleeve. The other end of the locking rod overlaps with a protrusion, and the protrusion is provided on one of the hinge members.

[0012] Preferably, the elastic guiding assembly includes a guide frame, with lifting rings fixedly connected above the two inner guide frames. A conveying structure is provided on the guide frame, and a third gear is installed on the conveying shaft of the conveying structure. The third gear meshes with a second gear, which is mounted on a transmission shaft. A first gear is installed at one end of the transmission shaft, and the first gear can mesh with a rack. The transmission shaft is rotatably mounted on a transmission frame via bearings, and the transmission frame is fixedly connected to the guide frame.

[0013] Preferably, two third springs and guide rods are fixedly connected to one side of the guide frame, wherein four of the third springs are fixedly connected to four side plates respectively, and the other four of the third springs are fixedly connected to four movable seats respectively, wherein four of the guide rods pass through the four side plates respectively, and the other four guide rods pass through the four movable seats respectively.

[0014] The method for using a multi-specification attitude correction and transmission system for current transformers includes the following steps: S1. When transporting small-sized current transformers, the small-sized current transformers are transported by the conveying equipment. When the transformers are transported to the position of the elastic guide assembly, the motor drives the bidirectional screw to rotate. The two bidirectional screws are synchronously driven by the belt drive structure. The bidirectional screws drive the first nut and the second nut to move relative to each other, so that the elastic support assembly drives the elastic guide assembly to move. The relative movement of the two elastic guide assemblies corrects the direction of the small-sized current transformers with small deviations on both sides. S2. When the small-sized current transformer is severely misaligned, the conveying structure contacts the small-sized current transformer and continues to advance. At this time, the third spring is deformed by force. The rack and the first gear drive the transmission shaft to rotate. The transmission shaft drives the second gear and the third gear to drive the transmission shaft to rotate. The relative movement of the two conveying structures can correct the direction of the clamped small-sized current transformer. When the movable seat drives the contact switch to contact the second contact, the motor reverses and the two elastic guide components separate and reset. When the contact switch and the first contact are squeezed, the motor rotates forward and the elastic guide components move relative to each other to correct the direction. This process is repeated to accurately correct the posture of the small-sized current transformer. S3. When it is necessary to switch to a large-specification current transformer for calibration, the guide frame is pulled up by the lifting ring. When the telescopic rod and the first spring move upward past the minimum shortened stroke, the first spring returns to its original position to maintain stable support for the guide frame. At the same time, the protrusion disengages from the locking rod. At this time, the second spring drives the locking rod to disengage from the positioning port. At this time, the attitude calibration operation of the large-specification current transformer is carried out through the two outer elastic guide components.

[0015] Compared with the prior art, the present invention provides a multi-specification attitude correction and transmission system and method for current transformers, which has the following beneficial effects: 1. This current transformer multi-specification attitude correction conveying system and method allows for adjustment of the vertical position of the two inner elastic guide components via an elastic support assembly. The conveying channel mode can be freely switched according to production needs. When conveying large-specification current transformers, the inner elastic guide component moves upward, and the two outer elastic guide components cooperate to form a wide conveying channel, achieving stable centered conveying of a single large-specification current transformer and ensuring neat positioning of large components. When conveying small-specification current transformers, the two inner elastic guide components move downward, evenly dividing the original wide channel into two independent narrow channels, enabling parallel and synchronous conveying of two small-specification current transformers. This method eliminates the need for mold replacement and overall disassembly / reassembly, allowing for rapid production changeover of products of varying sizes. It is suitable for continuous production and correction operations of multiple specifications of current transformers on mixed lines.

[0016] 2. This multi-specification attitude correction conveying system and method for current transformers, when clamped by the elastic guide components, if the conveying attitude of the current transformer is skewed or there is a local bulge size deviation, causing the guide frame to fail to close to the set clamping width, the guide frame is compressed by the reaction force of the current transformer to the third spring. The backward displacement of the guide frame causes the rack and the first gear to drive each other, and drives the second and third gears to rotate through the transmission shaft. This, in turn, drives the conveying structures on both sides to move in opposite directions in a coordinated manner, automatically generating a rotational correction torque for the skewed current transformer. This allows the current transformer to automatically straighten at a small angle during continuous clamping and conveying, achieving automatic correction of attitude deviation, ensuring accurate and regular conveying attitude of the current transformer, and solving the problems of traditional equipment being unable to self-correct and having poor product attitude consistency.

[0017] 3. This multi-specification attitude correction conveying system and method for current transformers, through the adjustability of the elastic support component to the inner elastic guide component, enables the switching of multiple conveying channels. This provides the basic working conditions for mixed-line production of current transformers of different specifications. Whether it is single-channel centered conveying of large-specification current transformers or parallel conveying of dual-channel current transformers, it can provide a standardized clamping and conveying scenario for the elastic guide component. In the event of abnormal current transformer attitude, the drive component drives the elastic guide component to correct the offset and skew problems of different specifications of current transformers in real time during the conveying process. This ensures the centering accuracy of a single large-specification current transformer and the consistency of the parallel attitude of two small-specification current transformers. The two work together to achieve multiple functions such as universal conveying of multiple specifications of current transformers, flexible protection, and adaptive correction. At the same time, it achieves adaptive working conditions, greatly reducing the difficulty of equipment debugging and the cost of manual intervention, thus adapting to the needs of large-scale, automated, and high-precision conveying production of multiple models of current transformers.

Detailed Implementation

[0020] Example 1: Refer to Figures 1-8A multi-specification attitude correction and conveying system for current transformers includes a conveying device 100, on which a correction mechanism 200 is provided; The calibration mechanism 200 includes a drive assembly 201, which comprises four fixed seats 2011 and two bidirectional screws 2013. The two bidirectional screws 2013 are connected by a belt drive structure 2017. The bidirectional screws 2013 are rotatably mounted on the two fixed seats 2011 via two bearings. The fixed seats 2011 are fixedly connected to the conveying device 100. One of the bidirectional screws 2013 is fixedly connected to the output shaft of a motor 2012, which is mounted on the fixed seat 2011. Each of the two fixed seats 2011 is fixedly connected to a first contact 2015. The bidirectional screw 2013 has four threaded sections, with adjacent threaded sections arranged in opposite directions. Two first nuts 2014 and two second nuts 20110 are threadedly connected to the bidirectional screw 2013. The first nuts 2014 have positioning holes 20111, and the second nuts 20110 are equipped with movable seats 20. 19. Contact switches 2018 are installed on both sides above the movable base 2019. By contacting the first contact 2015 and the second contact 2024 through the contact switches 2018, the forward and reverse rotation control of the motor 2012 can be realized. This allows the elastic guide component 205 to be repeatedly corrected to ensure the accuracy of the current transformer's posture. The two movable bases 2019 are slidably connected to the slide rod 2016. The two ends of the slide rod 2016 are respectively fixedly connected to the two fixed bases 2011. The motor 2012 drives the bidirectional screw 2013 to rotate, and the two bidirectional screws 2013 rotate synchronously under the belt drive structure 2017. Then, the first nut 2014 and the second nut 20110 can be driven to move relative to each other through the threads in opposite directions, so that the elastic support component 203 drives the elastic guide component 205 to move. The two elastic guide components 205 can be combined to directly correct the current transformer that has a slight posture deviation. The drive assembly 201 is equipped with an adjustment assembly 202, which includes a bidirectional lead screw 2021. One end of the bidirectional lead screw 2021 is equipped with a handle. The bidirectional lead screw 2021 is rotatably mounted on the fixed base 2011 via two bearings. The two threads on the bidirectional lead screw 2021 are arranged in opposite directions. Two adjusting nuts 2022 are threadedly connected to the bidirectional lead screw 2021. Adjusting seats 2023 are mounted on the adjusting nuts 2022. The two adjusting seats 2023 are slidably connected to the slide rod 2016. A second contact 2024 is fixedly connected to one side of the adjusting seat 2023. By rotating the bidirectional lead screw 2021 with the handle, since the two threads on the bidirectional lead screw 2021 are arranged in opposite directions, the bidirectional lead screw 2021 can drive the adjusting nuts 2022 to move away from or towards each other. This can drive the adjusting seats 2023 and the second contact 2024 to move, thereby adjusting the moving distance of the elastic guide assembly 205 and effectively adapting to the attitude correction of current transformers of different specifications. The drive assembly 201 is also equipped with four elastic support assemblies 203. Each elastic support assembly 203 includes a telescopic rod 2031 and a first spring 2032. The two ends of the telescopic rod 2031 and the first spring 2032 are respectively fixedly connected to two connecting pieces 2033. Both connecting pieces 2033 are hinged to the hinge piece 2034 and the connecting seat 2036 respectively via pins. Through the telescopicity of the telescopic rod 2031 and the first spring 2032 and the directional nature of the pins, the up-and-down adjustment of the elastic guide assembly 205 can be satisfied. After adjustment, the first spring 2032 can support the elastic guide assembly 205 to maintain the stability of the elastic support assembly 203. A side plate 2037 is fixedly connected to one side of the hinge piece 2034. A toothed rod 204 is fixedly connected to one side of each of the two diagonally opposite side plates 2037 and the two diagonally opposite movable seats 2019. A locking sleeve 20310 is installed on the connecting seat 2036. A locking rod 2038 is slidably connected in 20310. One end of the locking rod 2038 is inserted into the positioning port 20111, and the other end of the locking rod 2038 is fixedly connected to the locking sleeve 20310 by a second spring 2039. The other end of the locking rod 2038 overlaps with a protrusion 2035, which is set on one of the hinges 2034. When the elastic guide component 205 is adjusted upward, the protrusion 2035 is separated from the locking rod 2038. At this time, the second spring 2039 drives the locking rod 2038 to disengage from the positioning port 20111. The connection between the connecting seat 2036 and the first nut 2014 is removed to avoid the two inner elastic guide components 205 from moving with the first nut 2014 when idle, thus avoiding the waste of kinetic energy. When the elastic guide component 205 moves downward and is put into use, the protrusion 2035 squeezes the locking rod 2038 into the positioning port 20111, thus ensuring the normal operation of the elastic guide component 205. Both ends of the drive assembly 201 and the two elastic support assemblies 203 on the corresponding sides are provided with elastic guide assemblies 205. The elastic support assemblies 203 are used to support the two inner elastic guide assemblies 205 and are also used for channel switching of current transformers of different sizes and specifications. The adjustment assembly 202 is used to adjust the travel of the outer elastic guide assemblies 205. The two inner elastic guide assemblies 205 and the two outer elastic guide assemblies 205 are respectively arranged opposite to each other to correct the attitude of the current transformer.

[0021] In this embodiment: the elastic support component 203 can adjust the vertical position of the two inner elastic guide components 205, and the conveying channel mode can be freely switched according to production needs. When conveying large-size current transformers, the inner elastic guide component 205 moves upward, and the two outer elastic guide components 205 cooperate to form a wide conveying channel, realizing the stable and centered conveying of a single large-size current transformer, ensuring that the large components are positioned neatly. When conveying small-size current transformers, the two inner elastic guide components 205 move downward, evenly dividing the original wide channel into two independent narrow channels, which can realize the parallel and synchronous conveying of two small-size current transformers. This method does not require changing the mold or disassembling the entire assembly and disassembly mechanism, and can quickly complete the production changeover of products of different sizes, adapting to the continuous production and calibration operations of mixed-line current transformers of multiple sizes.

[0022] Example 2: Refer to Figure 7 and Figure 9A multi-specification attitude correction conveying system for current transformers includes an elastic guide assembly 205. The elastic guide assembly 205 includes guide frames 2051. Lifting rings are fixedly connected to the top of the two inner guide frames 2051, allowing easy operation of the guide frames 2051 and adjustment of the position of the elastic guide assembly 205. A conveying structure 2052 is provided on the guide frames 2051. The conveying structure 2052 provides frictional traction in the conveying direction to the current transformer during clamping, achieving integrated clamping and conveying operations. A third gear 2057 is mounted on the conveying shaft of the conveying structure 2052, meshing with a second gear 2056. The second gear 2056 is mounted on a drive shaft 2055, and a first gear 2054 is mounted on one end of the drive shaft 2055. The first gear 2054 can engage with... The rack 204 meshes, and the drive shaft 2055 is rotatably mounted on the drive frame 2053 via bearings. The drive frame 2053 is fixedly connected to the guide frame 2051. Two third springs 2059 and guide rods 2058 are fixedly connected to one side of the guide frame 2051. Through the elastic extensibility of the third springs 2059, elastic yielding can be achieved during the clamping process of the current transformer, effectively buffering the clamping stress and avoiding problems such as product extrusion deformation and shell damage caused by traditional rigid clamping. Four third springs 2059 are fixedly connected to four side plates 2037 respectively, and another four third springs 2059 are fixedly connected to four movable seats 2019 respectively. Four guide rods 2058 pass through the four side plates 2037 respectively, and another four guide rods 2058 pass through the four movable seats 2019 respectively.

[0023] In this embodiment: when the current transformer is clamped by the elastic guide assembly 205, if the current transformer's conveying posture is skewed or there is a local bulge size deviation, causing the guide frame 2051 to fail to close to the set clamping width, the guide frame 2051 is compressed by the reaction force of the current transformer, compressing the third spring 2059. The guide frame 2051 is displaced backward, causing the rack 204 to drive the first gear 2054, and through the transmission shaft 2055, it drives the second gear 2056 and the third gear 2057 to rotate, thereby driving the two conveying structures 2052 on both sides to move in opposite directions in a coordinated manner. This automatically generates a rotational correction torque for the skewed current transformer, enabling the current transformer to automatically straighten at a small angle during continuous clamping and conveying, realizing automatic correction of posture deviation, ensuring that the current transformer's conveying posture is accurate and regular, and solving the problems of traditional equipment being unable to self-correct and having poor product posture consistency.

[0024] Example 3: Reference Figures 1-3A multi-specification attitude correction and conveying system for current transformers includes a correction mechanism 200. The correction mechanism 200 includes a drive assembly 201, an adjustment assembly 202, and four elastic support assemblies 203. Elastic guide assemblies 205 are provided at both ends of the drive assembly 201 and on the corresponding sides of the two elastic support assemblies 203. The elastic support assemblies 203 support the two inner elastic guide assemblies 205 and also switch the channels for current transformers of different sizes. The adjustment assembly 202 adjusts the travel of the outer elastic guide assemblies 205. The two inner elastic guide assemblies 205 and the two outer elastic guide assemblies 205 are respectively arranged opposite to each other to correct the attitude of the current transformer.

[0025] In this embodiment, the adjustability of the elastic support component 203 to the inner elastic guide component 205 enables the switching of multiple transport channels, providing a basic working condition for the mixed-line production of current transformers of different specifications. Whether it is the single-channel centered transport of large-specification current transformers or the parallel transport of small-specification current transformers in two channels, the elastic guide component 205 can provide a standardized clamping and transport scenario. In the event of abnormal current transformer posture, the drive component 201 drives the elastic guide component 205 to correct the offset and skew problems of different specifications of current transformers during transport in real time, ensuring the centering accuracy of a single large-specification current transformer and the consistency of the parallel posture of two small-specification current transformers. The two work together to achieve multiple functions such as universal transport of multiple specifications of current transformers, flexible protection, and adaptive correction. At the same time, it achieves adaptive working condition, greatly reducing the difficulty of equipment debugging and the cost of manual intervention, thereby adapting to the needs of large-scale, automated, and high-precision transport production of multiple models of current transformers.

[0026] The method for using a multi-specification attitude correction and transmission system for current transformers includes the following steps: S1. When transporting small-sized current transformers, the small-sized current transformers are transported by the conveying equipment 100. When the transformers are transported to the position of the elastic guide component 205, the motor 2012 drives the bidirectional screw 2013 to rotate. The two bidirectional screws 2013 are synchronously driven by the belt drive structure 2017. The bidirectional screws 2013 drive the first nut 2014 and the second nut 20110 to move relative to each other, so that the elastic support component 203 drives the elastic guide component 205 to move. The relative movement of the two elastic guide components 205 corrects the direction of the small-sized current transformers with small deviations on both sides. S2. When the small-sized current transformer is severely misaligned, the conveying structure 2052 contacts the small-sized current transformer and continues to advance. At this time, the third spring 2059 is deformed by force. The rack 204 and the first gear 2054 are driven. The first gear 2054 drives the transmission shaft 2055 to rotate. The transmission shaft 2055 drives the second gear 2056 and the third gear 2057 to rotate. The relative movement of the two conveying structures 2052 can correct the direction of the clamped small-sized current transformer. When the movable seat 2019 drives the contact switch 2018 to contact the second contact 2024, the motor 2012 reverses, causing the two elastic guide components 205 to separate and reset. When the contact switch 2018 and the first contact 2015 are squeezed, the motor 2012 rotates forward, and the relative movement of the elastic guide components 205 is corrected. This process is repeated to accurately correct the posture of the small-sized current transformer. S3. When it is necessary to switch to a large-specification current transformer for calibration, the guide frame 2051 is pulled up by the lifting ring. When the telescopic rod 2031 and the first spring 2032 move upward past the minimum shortened stroke, the first spring 2032 returns to its original position and provides stable support to the guide frame 2051. At the same time, the protrusion 2035 disengages from the locking rod 2038. At this time, the second spring 2039 drives the locking rod 2038 to disengage from the positioning port 20111. At this time, the attitude calibration operation of the large-specification current transformer is carried out through the two outer elastic guide components 205.

10. A method for using a multi-specification attitude correction and conveying system for current transformers, characterized in that, Includes the following steps: S1. When transporting a small-sized current transformer, the small-sized current transformer is transported by the conveying equipment (100). When it is transported to the position of the elastic guide component (205), the motor (2012) drives the bidirectional screw (2013) to rotate. The two bidirectional screws (2013) are synchronously driven by the belt drive structure (2017). The bidirectional screws (2013) drive the first nut (2014) and the second nut (20110) to move relative to each other, so that the elastic support component (203) drives the elastic guide component (205) to move. The relative movement of the two elastic guide components (205) corrects the direction of the small-sized current transformer with small deviations on both sides. S2. When the small-sized current transformer is severely misaligned, the conveying structure (2052) contacts the small-sized current transformer and continues to advance. At this time, the third spring (2059) is deformed by force. The rack (204) and the first gear (2054) are driven. The first gear (2054) drives the drive shaft (2055) to rotate. The drive shaft (2055) drives the second gear (2056) and the third gear (2057) to drive, so that the two conveying structures (2052) can move relative to each other. The small-sized current transformer is rotated for correction. When the movable seat (2019) drives the contact switch (2018) to contact the second contact (2024), the motor (2012) reverses, causing the two elastic guide components (205) to separate and reset. When the contact switch (2018) and the first contact (2015) are pressed together, the motor (2012) rotates forward, and the elastic guide components (205) move relative to each other for correction. This process is repeated to accurately correct the posture of the small-sized current transformer. S3. When it is necessary to switch to a large-specification current transformer for transmission calibration, the guide frame (2051) is pulled up by the lifting ring. When the telescopic rod (2031) and the first spring (2032) move upward past the minimum shortened stroke, the first spring (2032) resets to maintain stable support for the guide frame (2051). At the same time, the protrusion (2035) disengages from the locking rod (2038). At this time, the second spring (2039) drives the locking rod (2038) to disengage from the positioning port (20111). At this time, the attitude calibration operation of the large-specification current transformer is carried out through the two outer elastic guide components (205).
