Description

Technical Field

[0001] This utility model relates to the field of electrical automation technology, specifically an electrical automation positioning and detection device. Background Technology

[0002] Against the backdrop of the deep application of industrial automation technology, electrical automation positioning and testing equipment is mainly used to realize the automated positioning and precise detection of various objects in the electrical field, providing key technical support for the entire life cycle operation of electrical equipment. In the production and assembly process, the equipment can automatically calibrate the position of key electrical components such as motor rotors and stators, circuit breaker contacts and transformer cores, ensuring that the coaxiality and alignment accuracy of the components during assembly meet the process standards. At the same time, in intelligent manufacturing production lines, it can complete the gripping and positioning of electrical workpieces, the calibration of the welding position of circuit board components, and the positioning verification of the wiring terminals inside the electrical cabinet.

[0003] Currently, testing equipment varies significantly in size and specifications due to different application scenarios and testing functions. For heavier testing equipment, the conveying system needs to overcome higher loads to drive the equipment to move, which can easily lead to a decrease in speed and prolong the station transfer time. When the testing equipment gets stuck on the conveyor belt or the transmission belt slips, the increased speed of the conveying system causes the equipment to get stuck on the conveying equipment, which in turn causes the equipment on the conveying track to collide. Such collisions may not only cause damage to the outer shell of the testing equipment and misalignment of internal precision components, but also lead to deviations in testing accuracy.

[0004] Therefore, this utility model provides an electrical automation positioning and detection device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electrical automation positioning and detection device. It solves the problem mentioned above where, for heavier detection equipment, the conveying system needs to overcome a higher load to drive the equipment to move, which easily leads to a decrease in rotational speed and prolongs the station transfer time. Conversely, for lighter detection equipment, due to the reduced load requirement, the conveying system can easily maintain a higher rotational speed, which makes the equipment prone to inertial displacement during the conveying process, thus causing collisions between the equipment and the conveying track.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrical automation positioning and detection device, comprising: The equipment support has multiple sets of conveyor rollers rotatably connected to it. One of the conveyor rollers is driven by a motor, and the multiple conveyor rollers are connected to each other by belt pairs. A differential mechanism is located at one end of the equipment support, and the differential mechanism is connected to another conveyor roller via a transmission. The differential mechanism includes a drive shaft connected to another conveyor roller via a belt pair, and an outer shaft is sleeved on the drive shaft. A rotating block is fixedly connected to the middle position of the drive shaft, and centrifugal blocks are respectively connected to the upper and lower ends of the rotating block. Both centrifugal blocks are fixedly connected by a spring. The outer shaft is connected to a correction mechanism for correcting items via a belt pair, so that when the speed of the conveyor roller increases, under the action of centrifugal force, the two centrifugal blocks overcome the tension of the spring, thereby making the centrifugal blocks contact the inner surface of the outer shaft, so that when the drive shaft rotates, it drives the outer shaft to rotate through the rotating blocks.

[0007] Preferably, the upper end of the equipment support is movably connected to a pair of detection mechanisms for detection. The detection mechanism includes a gantry and two fixed frames movably connected to both ends of the equipment support. An X-axis moving component for moving the gantry is provided between the gantry and the fixed frames. A detection component is installed on one side of the gantry via a Y-axis moving component. A Z-axis moving component is also provided between the detection component and the gantry.

[0008] Preferably, the front end of the detection component is movably connected to a detection head for electrical detection, and rubber gaskets are fixedly connected to the two ends of the detection head.

[0009] Preferably, friction guards are provided on the outer sides of both centrifugal blocks, and the inner ring of the outer shaft is provided with friction patterns that match the friction guards.

[0010] Preferably, the correction mechanism includes a fixed base fixed to the bottom of the equipment bracket. Both ends of the fixed base are provided with fixed plates, and a bidirectional lead screw is movably connected to the two fixed plates. Both ends of the bidirectional lead screw are fitted with lead screw seats, and the two lead screw seats are fixedly connected to the fixed plates by springs. A ratchet shaft is fixedly connected to the end of the bidirectional lead screw, and a ratchet wheel matching the ratchet shaft is sleeved on the outside of the bidirectional lead screw. A push plate for correction is fixedly connected to both lead screw seats.

[0011] Preferably, both ends of the fixed base are provided with rails to prevent the lead screw seat from rotating, and the bottom of the lead screw seat is provided with a sliding groove that matches the rail. Soft rubber pads are fixedly connected to the opposite sides of the two push plates, and the ratchet is connected to the drive shaft through a belt pair.

[0012] This utility model provides an electrical automation positioning and detection device. Compared with the prior art, it has the following advantages: (1) The electrical automation positioning and detection equipment, through the coordinated action of the transmission shaft, centrifugal block, spring 1 and friction guard plate, when the item to be detected slips or gets stuck on the conveyor belt, the conveyor roller speed increases, the centrifugal block opens under the action of centrifugal force to overcome the tension of spring 1, and the friction guard plate is in contact with the outer shaft, which not only transmits power to the correction mechanism to avoid the inertial deviation of light objects, but also suppresses the speed too fast through friction damping. When conveying heavy objects, the load torque is greater than the rated torque of the motor, the conveyor roller speed slows down, the centrifugal block resets and separates from the outer shaft, avoiding the correction mechanism from adding extra load, and the auxiliary motor balances the power by reducing speed to prevent the motor from overload, ensuring the stable conveying of items of different weights.

[0013] (2) This electrical automation positioning and detection equipment improves the accuracy and safety of automated detection. The correction mechanism relies on a two-way lead screw, lead screw seat, push plate and spring 2. Under the drive of the differential mechanism, the two-way lead screw drives the lead screw seat and push plate to move closer together. Combined with the track limit, the object is centered and positioned. Spring 2 helps the push plate to reset. The detection mechanism adjusts the position of the gantry and the detection component through the X-axis moving component, Y-axis moving component and Z-axis moving component, so that the detection head is accurately connected to the detection part. The two work together to avoid the object offset from affecting the detection accuracy. The multi-axis adjustment covers multiple detection points. The soft rubber pad of the push plate and the rubber pad of the detection head protect the object from damage. It meets the accuracy and safety requirements of object positioning and detection in electrical automation scenarios. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] Please see Figures 1 to 5 An electrical automation positioning and detection device, comprising: The equipment support 1 has multiple sets of conveyor rollers 3 rotatably connected to it. One of the conveyor rollers 3 is driven by a motor 2, and the multiple conveyor rollers 3 are connected to each other by belt pairs. The differential mechanism 5 is located at one end of the equipment support 1, and the differential mechanism 5 is connected to the other conveyor roller 3 for transmission. The differential mechanism 5 includes a drive shaft 52 connected to another conveyor roller 3 via a belt pair, and an outer shaft 51 is sleeved on the drive shaft 52. A rotating block 54 is fixedly connected to the middle position of the drive shaft 52, and centrifugal blocks 53 are respectively connected to the upper and lower ends of the rotating block 54. Both centrifugal blocks 53 are fixedly connected by springs 55. The outer shaft 51 is connected to a correction mechanism 6 for correcting items via a belt pair, so that when the speed of the conveyor roller 3 increases, under the action of centrifugal force, the two centrifugal blocks 53 overcome the tension of springs 55, thereby making the centrifugal blocks 53 contact the inner side of the outer shaft 51. When the drive shaft 52 rotates, it drives the outer shaft 51 to rotate through the rotating block 54. Friction guards 56 are provided on the outer side of both centrifugal blocks 53, and the inner ring of the outer shaft 51 and the friction guards 56 are provided with friction patterns that match the friction guards 56. During operation, motor 2 is started first. Motor 2 outputs power to drive the conveyor roller 3, which is directly driven by it, to rotate. Because multiple conveyor rollers 3 are connected by belt pairs, power can be synchronously transmitted to all conveyor rollers 3, forming a stable conveying channel to transport the items to be inspected. The drive shaft 52, connected to one of the conveyor rollers 3 via a belt pair, will rotate synchronously with the speed of the conveyor roller 3. When the item to be inspected gets stuck on the conveyor belt or slips, the pressure of the item on the conveyor roller 3 is relatively small, and the resistance that the conveying system needs to overcome is low. At this time, the load torque is much less than the rated torque of motor 2. 2 can easily maintain or even increase the rotational speed of the conveyor roller 3, thus increasing the rotational speed of the conveyor roller 3. The rotational speed of the drive shaft 52 also increases synchronously. When the drive shaft 52 rotates, it drives the rotating block 54, which is fixedly connected to it, to rotate synchronously. Under the action of centrifugal force, the centrifugal blocks 53 connected to the upper and lower ends of the rotating block 54 gradually overcome the tension of the spring 55 and open away from the axis of the drive shaft 52 until the friction guard plate 56 on the outer side of the centrifugal block 53 completely contacts the friction grooves on the inner ring of the outer shaft 51. With the help of the frictional force between the friction guard plate 56 and the outer shaft 51, the drive shaft... 52 can drive the outer shaft 51 to rotate synchronously through the rotating block 54. The damping generated when the friction guard plate 56 contacts the outer shaft 51 suppresses the problem of excessive speed of the conveying roller 3 due to insufficient load, and prevents the speed of light objects from running out of control, so as to avoid the positional deviation of light objects due to high speed and large inertia. When conveying heavier objects, the pressure of the objects on the conveying roller 3 is greater, and the conveying system needs to overcome greater resistance. At this time, the load torque is greater than the rated torque of the motor 2. According to the power formula, the rated power of the motor 2 is fixed. When the load torque exceeds the rated torque of the motor 2, the motor... 2 cannot output enough torque to maintain the original speed of the conveyor roller 3, so the speed will decrease to avoid overload damage to the motor 2 due to power over-limit. Therefore, the speed of the conveyor roller 3 will slow down, and the speed of the drive shaft 52 will also slow down synchronously. When the speed of the drive shaft 52 slows down, the centrifugal force generated by the centrifugal block 53 is less than the tension of the spring 55. The spring 55 will pull the centrifugal block 53 back to the axis of the drive shaft 52, so that the friction guard plate 56 on the outside of the centrifugal block 53 separates from the inner ring of the outer shaft 51, and the outer shaft 51 stops rotating, reducing the extra load on the conveying system. Example

[0018] Please see Figures 1 to 5This embodiment provides a technical solution based on Embodiment 1: A pair of detection mechanisms 4 for detection are movably connected to the upper end of the equipment bracket 1. The detection mechanism 4 includes a gantry frame 41 and two fixed frames 42 movably connected to both ends of the equipment bracket 1. An X-axis moving assembly 43 for moving the gantry frame 41 is provided between the gantry frame 41 and the fixed frames 42. A detection assembly 46 is installed on one side of the gantry frame 41 via a Y-axis moving assembly 44. A Z-axis moving assembly 45 is also provided between the detection assembly 46 and the gantry frame 41. A detection head 47 for electrical detection is movably connected to the front end of the detection assembly 46. Rubber pads are fixedly connected to the edges of both ends of the detection head 47. The correction mechanism 6 includes a fixed base 61 fixed to the bottom of the equipment bracket 1. Both ends of the base 61 are provided with fixing plates 62, and a bidirectional lead screw 67 is movably connected to the two fixing plates 62. Both ends of the bidirectional lead screw 67 are connected with lead screw seats 64, and the two lead screw seats 64 are fixedly connected to the fixing plates 62 by springs 66. A ratchet shaft 69 is fixedly connected to the end of the bidirectional lead screw 67, and a ratchet 68 matching the ratchet shaft 69 is sleeved on the outside of the bidirectional lead screw 67. Push plates 65 for correction are fixedly connected to both lead screw seats 64. Both ends of the fixed base 61 are provided with rails 63 to prevent the lead screw seats 64 from rotating, and the bottom of the lead screw seats 64 is provided with a sliding groove matching the rails 63. Soft rubber pads are fixedly connected to the opposite sides of the two push plates 65. The ratchet 68 is connected to the drive shaft 52 by a belt pair. During operation, when the outer shaft 51 rotates, it transmits power to the ratchet 68 of the straightening mechanism 6 via a belt pair. The ratchet 68 meshes with the ratchet shaft 69 fixed at the end of the double-acting screw 67. Because the ratchet 68 and ratchet shaft 69 have a unidirectional transmission characteristic, they can only drive the double-acting screw 67 to rotate in one direction (this direction ensures that the screw seat 64 only moves towards each other, restricting the screw seat 64 from rotating away from each other). This causes the double-acting screw 67 to rotate around its own axis. The rails 63 set at both ends of the fixed base 61 restrict the rotation of the screw seat 64, preventing the screw seat 64 from rotating with the double-acting screw 67 and allowing it to move linearly along the rails 63. The threads at both ends of the bidirectional lead screw 67 are in opposite directions. Under the driving force of the threads, the two lead screw seats 64 move towards each other. As the lead screw seats 64 move, they synchronously push the push plate 65, which is fixedly connected to them, towards the object to be corrected. This corrects the object stuck on the conveyor belt or slipping on the conveyor belt (and prevents the conveyor roller 3 from rotating due to goods getting stuck on the conveyor belt or slippage caused by the conveying equipment). The soft rubber pads fixed to the opposite sides of the push plate 65 prevent direct rigid contact between the push plate 65 and the object, preventing damage to the object's outer shell or surface. When the object correction is complete or the outer shaft 51 stops rotating (i.e., when conveying heavy objects and the conveyor roller 3 rotates slowly), the soft rubber pads prevent direct rigid contact between the push plate 65 and the object, preventing damage to the object's outer shell or surface. When the load torque exceeds the rated torque of motor 2, the speed of conveyor roller 3 slows down, and the differential mechanism 5 does not drive the outer shaft 51. The bidirectional lead screw 67 loses its power source. At this time, spring 66, which is fixedly connected to both lead screw seat 64 and fixed plate 62, releases its tension, pulling lead screw seat 64 back towards the fixed plate 62. When lead screw seat 64 resets, it drives push plate 65 back to its initial position, preventing push plate 65 from obstructing the low-speed conveyed heavy object, reducing the extra load on motor 2 when driving the heavy object, and assisting motor 2 in maintaining the heavy object conveying state more stably. This prevents the speed of conveyor roller 3 from further decreasing due to load accumulation. Simultaneously, for detection needs, the detection mechanism 4 can achieve accurate detection through coordinated adjustment of multi-axis components. Adjusting the X-axis moving component 43 can drive the gantry 41 to move horizontally in the X direction along the fixed frame 42 movably connected to both ends of the equipment support 1, achieving lateral coverage of the detection area. Adjusting the Y-axis moving component 44 can drive the detection component 46 to move horizontally in the Y direction, so that the detection component 46 can accurately align with different detection points of the item. Adjusting the Z-axis moving component 45 can control the vertical height of the detection component 46 relative to the gantry 41, so that the detection head 47 movably connected to the front end of the detection component 46 fits against the part to be detected. The rubber pads fixed at both ends of the detection head 47 can play a buffering role when the detection head 47 contacts the item, preventing the detection head 47 or the detection surface of the item from being damaged by collision.

[0019] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0020] Working Principle: During operation, motor 2 is started, and the output power of motor 2 drives the conveyor roller 3 directly connected to it to rotate. Since multiple conveyor rollers 3 are connected by belt pairs, the power can be synchronously transmitted to all conveyor rollers 3 on the equipment support 1, so that all conveyor rollers 3 run synchronously. The item to be tested enters the working area of ​​the equipment as the conveyor rollers 3 rotate. During the conveying process, if the item slips or gets stuck on the conveyor belt, the load on the conveyor roller 3 is small, and the load torque is less than the rated torque of motor 2. The high speed of motor 2 increases, so the speed of conveyor roller 3 will increase. The drive shaft 52, which is connected to the conveyor roller 3 by the belt pair, rotates synchronously as the speed of conveyor roller 3 increases. 2 drives the rotating block 54 to rotate. The centrifugal blocks 53 at both ends of the rotating block 54 open under the action of centrifugal force, overcoming the tension of the spring 55. The friction guard plate 56 on the outside of the centrifugal block 53 is in contact with the friction texture of the inner ring of the outer shaft 51. On the one hand, the transmission shaft 52 drives the outer shaft 51 to rotate through the rotating block 54. The outer shaft 51 drives the ratchet 68 of the straightening mechanism 6 to rotate through the belt pair. The ratchet 68 meshes with the ratchet shaft 69 in one direction to drive the double-direction screw 67 to rotate. The screw seat 64 moves along the track 63 and pushes the push plate 65 to correct the position of the light object and avoid the inertial deviation of the light object. On the other hand, the damping effect of the friction guard plate 56 and the outer shaft 51 can help suppress the excessive speed of the conveyor roller 3. If the weight of the item is heavy, the motor 2. Unable to maintain the original speed of conveyor roller 3, the speed of conveyor roller 3 will slow down. The transmission shaft 52 slows down synchronously with the slowdown of conveyor roller 3. The centrifugal force of centrifugal block 53 decreases and is pulled back to its original position by spring 55. Friction guard plate 56 separates from outer shaft 51, and outer shaft 51 stops rotating. This state avoids the operation of the straightening mechanism 6 from increasing the extra load and reduces the burden on motor 2 to drive the heavy object. The auxiliary motor 2 balances the power by reducing the speed to avoid overload damage. When the item reaches the inspection station after being straightened by the straightening mechanism 6, conveyor roller 3 pauses or maintains low speed operation, and the inspection mechanism 4 starts working. The lateral position of gantry 41 is adjusted by the X-axis moving assembly 43, and the Y-axis moving assembly... The component 44 adjusts the longitudinal position of the detection component 46, and the Z-axis moving component 45 adjusts the height of the detection component 46. The three components work together to precisely move the detection head 47 to the part to be tested, and complete the testing of electrical performance (such as the continuity of the wiring terminal and the detection of component parameters) or positional accuracy (such as the coaxiality calibration of the component). After the test is completed, the conveying roller 3 resumes operation and drives the item away from the testing station. At the same time, the spring 66 in the correction mechanism 6 pulls the lead screw seat 64 to reset towards the fixed plate 62. The lead screw seat 64 drives the push plate 65 back to the initial position. The detection mechanism 4 is adjusted to the initial state through the multi-axis component, and the equipment enters the next testing cycle to realize the continuous positioning test of the electrical automation equipment.
