Description

Technical Field

[0001] This utility model relates to the field of testing platform technology, specifically to a non-destructive testing device for mechanical and electronic equipment based on multi-sensor fusion. Background Technology

[0002] Multi-sensor fusion non-destructive testing (NDT) devices for electromechanical equipment are testing equipment that integrates multiple sensor technologies with electromechanical design. Leveraging the collaborative sensing capabilities of different sensors, they can inspect the internal and surface conditions of equipment without damaging its original structure and performance. Widely used in electronic components, precision mechanical parts, and other fields, they provide technical support for equipment quality control and safe operation, representing a significant technological direction in modern industrial testing.

[0003] Utility model patent CN223244401U discloses a convenient testing platform for electronic devices. This platform includes a base, a vertical plate fixedly connected to the upper surface of the base, an adjusting rod fixedly connected to the upper surface of the vertical plate, a testing component mounted on the outer surface of the adjusting rod, a magnifying glass at the front end of the testing component, and a placement plate on the upper part of the base. The position of the electronic device can be adjusted by rotating the threaded rod, eliminating the need for frequent adjustments to the sliding block position or frequent fixing and locking of the sliding block. This significantly reduces the number of steps required for operation, improves the efficiency of electronic device testing, and facilitates testing. It is highly practical, simple to operate, and solves the problem of existing electronic device testing platforms being inconvenient for testing electronic devices.

[0004] This convenient electronic equipment testing station uses a bidirectional threaded rod assembly in the guide groove to drive a clamping plate to fix the electronic equipment. The contact area between the clamping plate and the electronic equipment relies on springs and rubber pads for cushioning. However, this fixing method has limitations for small electronic equipment with irregular shapes: the clamping plate can only apply clamping force from both sides, which cannot adapt to the irregular shape of the equipment and is prone to local contact failure. As a result, the equipment under test is prone to shaking when slightly affected by external forces after being placed, affecting the stability of the test. In view of this, we propose a multi-sensor fusion non-destructive testing device for mechanical and electronic equipment. Utility Model Content

[0005] The purpose of this invention is to provide a non-destructive testing device for electromechanical equipment with multi-sensor fusion, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-sensor fusion non-destructive testing device for electromechanical equipment includes a testing platform with a movable arm and a testing head. A through-hole is located at the center of the top surface of the testing platform. Several positioning cavities are located on the top surface of the testing platform surrounding the sliding hole. Support rods are fitted into the corresponding positioning cavities according to the size of the equipment to be inspected, so that the multiple support rods support the bottom surface of the equipment. A suction and fixing mechanism is slidably connected in the sliding hole. The suction and fixing mechanism includes a movable rod fitted in the sliding hole, with a plate base at the bottom end of the movable rod and a suction cup installed at the top end. The plate base is connected to a negative pressure pump via an air pipe. Under the operation of the negative pressure pump, the suction cup adheres to the bottom end of the equipment to be inspected. Under the pull of the gravity of the suction and fixing mechanism itself, the equipment to be inspected is pressed against the support rods. A push mechanism is also provided at the bottom end of the testing platform for moving the suction and fixing mechanism along the sliding hole.

[0008] Preferably, the positioning cavities are arranged in a rectangular array on the top surface of the testing platform, and the bottom end of the support rod is provided with a seat, through which the support rod is embedded in the positioning cavity;

[0009] Preferably, a magnet is embedded at the bottom of the mounting base, and a sheet-like iron plate is fixed at the bottom of the positioning cavity. The mounting base is attracted to the iron plate by the magnet.

[0010] In these two settings, the positioning cavity of the rectangular array expands the installation and adaptation range of the support rod, the insert enhances the installation stability of the support rod, and the magnetic block and iron plate cooperate to prevent the support rod from shifting during detection.

[0011] Preferably, the movable rod is hollow, and a through hole communicating with the inside of the movable rod is opened on the outer peripheral surface of the disc base. A pipe joint is installed at the opening of the through hole, and the end of the air pipe connected to the negative pressure pump is sleeved on the pipe joint. The negative pressure pump is installed on the bottom surface of the testing platform.

[0012] In this setup, the hollow structure of the movable rod and the through hole form an air passage, the pipe joint ensures a secure air pipe connection, and the negative pressure pump creates negative pressure inside the suction cup to generate suction force.

[0013] Preferably, the periphery of the movable rod is provided with a plurality of vertical guide rods arranged in a circular array around the axis of the movable rod. The bottom end of the guide rod is provided with a stop to prevent the plate seat from sliding down. The top end of the guide rod passes through the plate seat and is fixed to the bottom surface of the detection table. The plate seat and the guide rod are slidably connected.

[0014] In this setup, the guide rods of the ring array ensure that the movable rod slides vertically without deviation, the stop blocks prevent the attraction fixing mechanism from falling off, and the sliding connection enables stable movement of the disc base.

[0015] Preferably, a threaded post is fixed to the bottom end of the disk base, and a plurality of counterweights are threadedly connected to the threaded post;

[0016] In this setup, the threaded column facilitates the installation and removal of the counterweight, which can increase the attraction of the fixing mechanism and adapt to the fixing requirements of equipment of different weights.

[0017] Preferably, the push mechanism includes a rotating rod and a lever plate mounted on the rotating rod. Support seats are fixed at the front and rear edges of the bottom surface of the test table. The rotating rod passes through the two support seats and is rotatably connected to the support seats. The end of the lever plate is bent and can abut against the bottom surface of the plate. By moving the rotating rod, the rotating rod can drive the lever plate to push the plate upward, so that the plate drives the movable rod to move upward along the sliding hole and contact the bottom surface of the equipment to be tested.

[0018] In this setup, the support base provides stable support for the rotating rod, and the bent lever prevents slippage during operation. It converts the rotational motion of the rotating rod into the linear motion of the movable rod, enabling the suction cup to contact the device under inspection.

[0019] Preferably, both ends of the rotating rod are fixed with retaining rings, the two retaining rings are located on the outside of the two support seats respectively, and the end of the rotating rod is coaxially fixedly connected with a lever, which is used to drive the rotating rod to rotate. The tail end of the lever is fixed with a fixed sleeve, which is sleeved and fixed on the outside of the rotating rod.

[0020] In this configuration, the retaining ring restricts the axial movement of the rotating rod, the lever reduces the rotational operating force, and the fixed sleeve enhances the connection stability between the lever plate and the rotating rod.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This multi-sensor fusion non-destructive testing device for electromechanical equipment first sets support rods in corresponding positioning cavities according to the size of the equipment, so that the support rods provide multi-point support from the bottom surface of the equipment. Then, it is attracted from the center of the bottom end of the equipment by a suction cup. Combined with the gravity pull of the attraction and fixing mechanism, a two-way fixation is formed. The fixation method that combines multi-support rod support with suction cup adsorption can be adapted to small electronic devices with irregular appearance. This method does not rely on a regular clamping surface. Through the synergistic effect of multi-point support and central adsorption, it can avoid shaking of the equipment under inspection after placement and ensure the stability of the testing process.

Example

[0035] Please see Figures 1-4The multi-sensor fusion non-destructive testing device for electromechanical equipment includes a testing table 100, a movable arm 110 on the testing table 100, and a testing head 111 on the movable arm 110. The testing head 111 integrates various non-contact testing sensors to perform non-contact non-destructive testing on the electronic equipment to be tested placed on the testing table 100. The non-contact testing method can avoid damage to the surface of the equipment during the testing process, while multi-sensor fusion can improve the comprehensiveness and accuracy of the testing data.

[0036] like Figures 1-3 As shown, in this utility model, a through sliding hole 120 is provided at the center of the top surface of the testing platform 100. Several positioning cavities 130 are provided on the top surface of the testing platform 100 surrounding the sliding hole 120. Support rods 200 are fitted into the corresponding positioning cavities 130 according to the size of the equipment to be inspected, so that the multiple support rods 200 support the bottom surface of the equipment to be inspected. The positioning cavities 130 provide installation and positioning points for the support rods 200, facilitating flexible selection of installation positions according to the size of the equipment to be inspected. Multiple support rods 200 support the equipment to be inspected from multiple points on the bottom surface, adapting to different appearances. To meet the support requirements of the equipment and reduce uneven stress on certain parts of the equipment, several positioning cavities 130 are arranged in a rectangular array on the top surface of the testing table 100. This rectangular array of positioning cavities 130 can cover different areas of the top surface of the testing table 100, expanding the installation and adaptation range of the support rod 200. The bottom end of the support rod 200 is provided with a recess 210, which increases the contact area between the support rod 200 and the positioning cavity 130, improving the stability of the support rod 200 after installation. The support rod 200 is embedded in the positioning cavity 130 through the recess 210. A magnet 220 is embedded at the bottom end of the recess 210. A sheet-like iron plate is fixed at the bottom of the positioning cavity 130. The recess 210 is attracted to the iron plate by the magnet 220. The attraction between the magnet 220 and the iron plate further fixes the position of the support rod 200, preventing displacement during testing.

[0037] like Figure 1 , Figure 2 and Figure 4As shown, specifically, a suction and fixing mechanism 300 is slidably connected in the sliding hole 120. The suction and fixing mechanism 300 includes a movable rod 310 sleeved in the sliding hole 120. The movable rod 310 provides a mounting carrier for the suction cup 312 and can drive the suction cup 312 to move up and down along the sliding hole 120. The movable rod 310 is hollow, and the hollow structure can serve as an airflow channel. A plate base 311 is provided at the bottom end of the movable rod 310, and a suction cup 312 is installed at the top end of the movable rod 310. The suction cup 312 can make close contact with the bottom end of the device under inspection, forming an adsorption force under negative pressure to fix the device under inspection. Position: The disc base 311 is connected to the negative pressure pump 140 via an air pipe. A through hole is opened on the outer peripheral surface of the disc base 311, which communicates with the interior of the movable rod 310. The through hole allows the air passage between the interior of the movable rod 310 and the outside, providing a channel for the negative pressure pump 140 to draw air from the suction cup 312. A pipe connector 313 is installed at the opening of the through hole. The end of the air pipe connected to the negative pressure pump 140 is sleeved on the pipe connector 313. The negative pressure pump 140 is installed on the bottom surface of the detection platform 100. The negative pressure pump 140 can draw air from the suction cup 312, so that a negative pressure is formed inside the suction cup 312, thereby generating an adsorption force. Under the operation of the negative pressure pump 140, the suction cup 312 is adsorbed onto the bottom of the device to be inspected. At this time, under the pull of the gravity of the suction fixing mechanism 300 itself, the device to be inspected is pressed against several support rods 200. The gravity of the suction fixing mechanism 300 and the suction force of the suction cup 312 work together to stably press the device to be inspected against the support rods 200, preventing the device from shaking after placement.

[0038] like Figure 4 As shown, further, a number of vertical guide rods 320 are arranged in a circular array around the axis of the movable rod 310. The circular array of guide rods 320 can provide guidance from multiple directions around the outer periphery of the movable rod 310, ensuring that the movable rod 310 remains vertical when sliding and avoiding deviation. The bottom end of the guide rod 320 is provided with a stop to prevent the disc base 311 from sliding down. The stop can limit the downward stroke of the disc base 311 and prevent the attraction fixing mechanism 300 from falling out of the sliding hole 120. The top end of the guide rod 320 passes through the disc base 311 and is fixed to the bottom surface of the detection table 100. The disc base 311 and the guide rod 320 are slidably connected. The sliding connection can realize the stable movement of the disc base 311 along the guide rod 320, thereby driving the movable rod 310 to slide synchronously.

[0039] like Figure 4 As shown, in addition, a threaded post 314 is fixed at the bottom of the base 311. The threaded post 314 provides a threaded connection structure for the counterweight 330, which facilitates the installation and removal of the counterweight 330. Several counterweights 330 are threadedly connected to the threaded post 314. The counterweights 330 can increase the overall gravity of the attraction and fixing mechanism 300, enhance the pulling and fixing effect of the equipment to be inspected, and adapt to the fixing requirements of equipment to be inspected of different weights. The number of counterweights 330 can be freely installed as needed.

[0040] It is worth noting that the negative pressure pump 140 involved in this utility model is a conventional technology and will not be described in detail here.

[0041] In this embodiment of the multi-sensor fusion non-destructive testing device for electromechanical equipment, the following steps are taken: First, according to the size of the electronic device to be tested, the support rod 200 with the mounting base 210 is attracted to the corresponding positioning cavity 130 on the top surface of the testing table 100 by the magnet block 220, thus completing the installation of the support rod 200; then, the electronic device to be tested is placed on the multiple support rods 200, so that the support rods 200 provide support from the bottom surface of the device; next, the disk base 311 is pushed along the guide rod 320, which drives the movable rod 310 along the sliding hole 120. Slide upwards until the suction cup 312 at the top of the movable rod 310 contacts the bottom of the device under inspection; finally, start the negative pressure pump 140 on the bottom of the test platform 100. The negative pressure pump 140 draws air from the suction cup 312 through the air pipe and pipe joint 313, causing the suction cup 312 to adsorb the device under inspection. At the same time, the fixed mechanism 300 pulls the device by its own weight, pressing the device against the support rod 200. Then, adjust the position of the test head 111 through the movable arm 110, and use the non-contact sensor in the test head 111 to perform non-destructive testing on the device. Example

[0042] To facilitate the movement of the movable rod 310 along the sliding hole 120, such as Figure 1 , Figure 2 and Figure 5 As shown, the bottom of the testing platform 100 is also provided with a push-pull mechanism 400 for moving the attraction fixing mechanism 300 along the sliding hole 120. The push-pull mechanism 400 can drive the attraction fixing mechanism 300 to move through mechanical transmission, eliminating the need to manually push the disc base 311 and improving the ease of operation. The push-pull mechanism 400 includes a rotating rod 410 and a lever plate 420 mounted on the rotating rod 410. The rotating rod 410 can serve as a power transmission carrier, driving the lever plate 420 to rotate synchronously. The lever plate 420 can directly contact the disc base 311 and apply a pushing force.

[0043] In this embodiment, support seats 150 are fixed at the front and rear edges of the bottom surface of the detection table 100. The support seats 150 provide mounting support for the rotating rod 410, ensuring that the rotating rod 410 can rotate stably. The rotating rod 410 passes through the two support seats 150 and is rotatably connected to the support seats 150. Both ends of the rotating rod 410 are fixed with retaining rings 411. The retaining rings 411 can restrict the axial movement of the rotating rod 410 and prevent the rotating rod 410 from slipping out of the support seat 150 during rotation. The two retaining rings 411 are located on the outer side of the two support seats 150 respectively. The end of the rotating rod 410 is coaxially fixedly connected with a lever 412. The lever 412 can increase the torque of the rotating rod 410, making it easier for the operator to drive the rotating rod 410 to rotate by turning the lever 412, reducing the operating force. The lever 412 is used to drive the rotating rod 410 to rotate.

[0044] Specifically, the end of the lever 420 is bent and can abut against the bottom surface of the disc base 311. The bent structure can increase the contact area between the lever 420 and the disc base 311, preventing the lever 420 from slipping off the bottom surface of the disc base 311 during the levering process. By levering the rotating rod 410, the rotating rod 410 can drive the lever 420 to push the disc base 311 upward, so that the disc base 311 drives the movable rod 310 to move upward along the sliding hole 120 and contact the bottom surface of the equipment to be inspected. This transmission process can convert the rotational motion of the rotating rod 410 into the linear motion of the disc base 311, realizing the precise lifting and lowering of the movable rod 310.

[0045] Furthermore, a fixing sleeve 421 is fixed to the tail end of the lever 420. The fixing sleeve 421 can enhance the connection stability between the lever 420 and the rotating rod 410 and prevent the lever 420 from being displaced relative to the rotating rod 410 during rotation. The fixing sleeve 421 is sleeved and fixed on the outside of the rotating rod 410.

[0046] In this embodiment of the multi-sensor fusion non-destructive testing device for mechanical and electronic equipment, the following steps are followed: First, the support rod 200 is installed and the electronic equipment to be tested is initially placed according to the steps in Embodiment 1. Then, the operator moves the lever 412 at the end of the rotating rod 410, causing the rotating rod 410 to rotate between the two support seats 150. At this time, the rotating rod 410 drives the lever 420 to rotate synchronously through the fixed sleeve 421. Next, the bent end of the lever 420 contacts the bottom surface of the disk seat 311 and applies an upward thrust, pushing the disk seat 311 to slide upward along the guide rod 320, thereby driving the movable rod 310 to rise along the sliding hole 120 until the suction cup 312 contacts the bottom end of the equipment to be tested. Finally, the negative pressure pump 140 is started to allow the suction cup 312 to adsorb the equipment. After the equipment is fixed, the position of the detection head 111 is adjusted by the movable arm 110 to perform non-destructive testing. After the test is completed, the negative pressure pump 140 is turned off, causing the suction cup 312 to lose its adsorption force and detach from the equipment to be tested. At this time, the equipment to be tested can be removed.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
