Description

Technical Field

[0001] This application relates to the field of ultrasonic testing technology, and in particular to an ultrasonic rapid testing device equipped with an automatic feeding structure. Background Technology

[0002] Ultrasonic testing equipment utilizes the phenomena of reflection, transmission, diffraction, scattering, and waveform conversion that occur when ultrasonic waves propagate in a medium. Inside the object under test, ultrasonic waves interact with the internal materials and defects, causing changes in their propagation direction and characteristics. By analyzing the characteristics of the received ultrasonic waves, the internal structure and defects of the object under test can be evaluated.

[0003] Chinese Patent CN208297685U discloses a non-destructive testing device for obtaining the internal state distribution of a lithium-ion battery. The device includes an ultrasonic detection unit, a scanning unit, and a frame auxiliary unit. Both the ultrasonic detection unit and the scanning unit are mounted on the auxiliary frame unit, which includes a constant temperature bath and a support frame. The support frame provides a mounting and support space for the ultrasonic detection unit and the scanning unit. The ultrasonic detection unit includes a liquid-immersed ultrasonic probe. The scanning unit enables relative movement between the ultrasonic detection unit and the lithium-ion battery under test. This invention allows for the detection of the internal state distribution of a battery, obtaining the internal state distribution of a lithium-ion battery, without damaging the battery structure or affecting its original performance.

[0004] Regarding the aforementioned technologies, in the prior art, when testing lithium batteries, a coupling agent is poured into a constant temperature bath, the lithium battery is placed in the constant temperature bath, and an ultrasonic probe is used to emit ultrasonic waves to test the lithium battery. However, the existing testing device is to test a single lithium battery in the constant temperature bath, which is only suitable for testing small batches of lithium batteries, thus reducing the applicability of the testing device. Utility Model Content

[0005] To improve the applicability of ultrasonic automatic testing equipment, this application provides an ultrasonic rapid testing device equipped with an automatic feeding structure.

[0006] This application provides an ultrasonic rapid testing device equipped with an automatic feeding structure, employing the following technical solution:

[0007] An ultrasonic rapid testing device equipped with an automatic feeding structure includes a body with several conveyor frames mounted on it. Each conveyor frame has a conveying assembly for moving the object to be tested. The conveying assembly includes conveyor rollers, support plates, conveyor belts, and a conveyor motor. One conveyor roller is rotatably connected to each end of the conveyor frame. The support plate is connected to the conveyor frame and located between two conveyor rollers, with its surface flush with the highest point of the conveyor roller. The conveyor belt is sleeved between two conveyor rollers. The conveyor motor is mounted on the conveyor frame and connected to one of the conveyor rollers. The body has a fixed frame, a movable frame, and an adjusting assembly for driving the movable frame. Both the fixed frame and the movable frame have rollers and rotating components for driving the rollers. The rollers have an opening at their top and contain a coupling fluid. An ultrasonic probe is mounted on the fixed frame and immersed in the coupling fluid. Similarly, an ultrasonic probe is mounted on the movable frame.

[0008] By adopting the above technical solution, before testing, the moving frame is moved to the designated position using the adjusting component. During testing, the rotating component rotates the rollers, and then several test objects are placed on the conveyor belt. The conveyor motor is started, causing the conveyor rollers to rotate and the conveyor belt to move, carrying the test objects along with it. As the test objects pass over the rollers, they are pressed together and moved by the two rotating rollers. Simultaneously, an ultrasonic probe is used to detect the test objects, achieving the effect of testing the test objects. Through the cooperation of the conveying component and the conveyor frame, operators can place several test objects at once and achieve automatic transport and testing of test objects. Compared with existing technologies, this makes the testing equipment suitable for large-scale testing of test objects, improving the applicability of ultrasonic automatic testing equipment.

[0009] Optionally, the conveyor frame is provided with a tensioning assembly, which includes a connecting column and a tensioning bolt. A rotating shaft passes through the conveyor roller, and one connecting column is connected to each end of the rotating shaft. The conveyor frame has a tensioning groove, and the surface of the connecting column has two sliding planes. The connecting column is slidably engaged in the tensioning groove through the sliding planes. The tensioning bolt is rotatably connected in the tensioning groove and is threadedly engaged with the connecting column.

[0010] By adopting the above technical solution, when tensioning the conveyor belt, rotating the tensioning bolt causes the conveyor roller to move through the cooperation of the sliding plane and the tensioning groove, thereby increasing the friction between the conveyor belt and the conveyor roller and achieving the effect of tensioning the conveyor belt.

[0011] Optionally, the conveyor frame is provided with a limiting component, which includes a support column, a limiting cylinder, an adjusting plate, and a locking bolt. The adjusting plate is located on one side of the conveyor frame and has an adjusting groove. The locking bolt passes through the adjusting groove and is threaded into the conveyor frame. Several support columns are connected to the other side of the conveyor frame and the adjusting plate. The limiting cylinder is installed on the support column.

[0012] By adopting the above technical solution, when restricting the object to be tested, the adjusting plate is moved to the designated position, and then the locking bolt is rotated to lock the adjusting plate, so that the object to be tested is restricted between the two limiting cylinders, achieving the effect of restricting the conveying position of the object to be tested. By adjusting the position of one limiting cylinder by adjusting the adjusting plate, the position of the object to be tested on the conveyor belt is restricted, ensuring that the object to be tested does not deviate significantly when entering between the two rollers, allowing the object to be smoothly pressed and moved by the rollers. Stable movement of the object to be tested is beneficial to the detection accuracy and improves the detection efficiency.

[0013] Optionally, the adjustment assembly includes an adjustment motor, a connecting block, a limiting rail, and an adjustment screw. The adjustment screw is rotatably connected to the machine body and parallel to the moving direction of the moving frame. The limiting rail is connected to the machine body and parallel to the adjustment screw. The adjustment motor is mounted on the machine body and coaxially connected to one end of the adjustment screw. The connecting block is connected to the bottom end of the moving frame. The adjustment screw passes through the connecting block and is threadedly engaged with the connecting block. The moving frame is slidably engaged on the limiting rail.

[0014] By adopting the above technical solution, when adjusting the position of the moving frame, the adjusting motor is started, causing the adjusting screw to rotate. Through the cooperation of the moving frame and the limiting rail, the connecting block moves, driving the moving frame to the designated position, thus achieving the effect of adjusting the position of the moving frame.

[0015] Optionally, the rotating component is a DC geared motor, the rotating component is vertically mounted on the fixed frame, the fixed frame is mounted on a rotating seat, the rotating component and the rotating seat are connected by a synchronous belt, the roller is vertically mounted on the rotating seat, and the roller and rotating component on the movable frame are similarly arranged.

[0016] By adopting the above technical solution, the DC geared motor is started, and the rotating seat is driven by the synchronous belt, so that the drum rotates stably and slowly. This reduces the slippage phenomenon when the drum rotates and improves the rotational stability of the drum.

[0017] Optionally, a plurality of limiting wheels are rotatably connected to the fixed frame at a position corresponding to the top of the roller, and the limiting wheels abut against the surface of the roller. Similarly, limiting wheels are provided on the movable frame.

[0018] By employing the above technical solution, the roller moves the object to be tested and needs to be pressed firmly against the surface of the object. This can lead to the roller tip tilting, potentially causing the object to also tilt and affecting the accuracy of the test. By limiting the roller's contact with the roller tip, the possibility of the roller tilting under stress is reduced, ensuring the object to be tested maintains its original position and improving the accuracy of the test.

[0019] Optionally, both the fixed frame and the movable frame are connected to a mounting plate, and an antistatic device is installed on the mounting plate, with the two antistatic devices arranged opposite each other.

[0020] By adopting the above technical solution, it is recognized that the surface of the object under test exhibits static electricity, which can interfere with ultrasonic testing and affect the accuracy of the test. By incorporating a static eliminator, static electricity is removed from the object before testing, minimizing interference during testing and improving the accuracy of the automated ultrasonic testing equipment.

[0021] Optionally, the roller surface is provided with coupling adhesive.

[0022] By adopting the above technical solution, the coupling adhesive is used to fill the air gap between the ultrasonic probe and the object under test to ensure effective sound wave transmission. It also increases the friction between the roller and the object under test, allowing the object under test to move smoothly, and can reduce the vibration when the roller rotates, thus ensuring the detection accuracy of the testing equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Before testing, the moving frame is moved to the designated position using the adjusting component. During testing, the rotating component rotates the rollers, and then several test objects are placed on the conveyor belt. The conveyor motor is started, causing the conveyor rollers to rotate and the conveyor belt to move, carrying the test objects along with it. As the test objects pass the rollers, they are pressed together and moved by the two rotating rollers. Simultaneously, an ultrasonic probe is used to detect the test objects, achieving the effect of testing them. Through the cooperation of the conveying component and the conveyor frame, operators can place several test objects at once and achieve automatic transport and testing of the test objects. Compared with existing technologies, this makes the testing equipment suitable for testing large batches of test objects, improving the applicability of ultrasonic automatic testing equipment.

[0025] 2. When confining the object to be tested, move the adjusting plate to the designated position, and then turn the locking bolt to lock the adjusting plate, so that the object to be tested is confined between the two limiting cylinders, thus achieving the effect of limiting the conveying position of the object to be tested. By adjusting the position of one limiting cylinder by adjusting the adjusting plate, the position of the object to be tested on the conveyor belt is restricted, ensuring that the object to be tested does not deviate significantly when entering between the two rollers, allowing the object to be smoothly moved and pressed against by the rollers. Stable movement of the object to be tested is beneficial to the detection accuracy and improves the detection efficiency. Attached Figure Description

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0033] This application discloses an ultrasonic rapid testing device equipped with an automatic feeding structure. (Refer to...) Figure 1 The ultrasonic rapid testing equipment equipped with an automatic feeding structure includes a body 1, on which several conveyor frames 11 are provided. In this embodiment, two are used as an example, with a gap between the two conveyor frames 11. The object to be tested in this embodiment is a lithium battery.

[0034] Reference Figure 1 and Figure 2A conveying assembly 2 is provided on the conveyor frame 11. The conveying assembly 2 includes conveying rollers 21, support plates 22, conveyor belts 23, and a conveyor motor 24. One conveying roller 21 is rotatably connected to each end of the conveyor frame 11. The support plates 22 are fixedly connected to the conveyor frame 11, and the top wall of the support plates 22 is flush with the highest point of the conveying rollers 21. The conveyor belt 23 is fitted between the two conveying rollers 21. The conveyor motor 24 is mounted on the conveyor frame 11 and is connected to one of the conveying rollers 21 via a synchronous belt.

[0035] During transport, the object to be tested is placed on the conveyor belt 23, the conveyor motor 24 is started, the conveyor roller 21 is rotated, and the conveyor belt 23 is moved to achieve the effect of transporting the object to be tested.

[0036] Reference Figure 3 A tensioning assembly 3 is provided on the conveyor frame 11, which includes a connecting column 31 and a tensioning bolt 32. A rotating shaft passes through another conveyor roller 21, and one connecting column 31 is fixedly connected to each end of the rotating shaft. A sliding surface 311 is provided on the connecting column 31. A tensioning groove 111 is formed on the conveyor frame 11, and the connecting column 31 is slidably fitted within the tensioning groove 111 through the sliding surface 311. The tensioning bolt 32 is rotatably connected within the tensioning groove 111, passes through the connecting column 31, and is threadedly engaged with the connecting column 31.

[0037] When tensioning the conveyor belt 23, rotating the tensioning bolt 32 causes the connecting column 31 to move through the cooperation of the sliding plane 311 and the tensioning groove 111, thereby driving the conveyor roller 21 to move. This increases the friction between the conveyor roller 21 and the conveyor belt 23, achieving the effect of tensioning the conveyor belt 23.

[0038] Reference Figure 2 A limiting component 4 is provided on the conveyor frame 11. The limiting component 4 includes a support column 41, a limiting cylinder 42, an adjusting plate 43, and a locking bolt 44. The adjusting plate 43 is located on one side of the conveyor frame 11 and has an adjusting groove. The locking bolt 44 passes through the adjusting groove and the conveyor frame 11 and is threaded into the conveyor frame 11. Several support columns 41 are fixedly connected to the other side of the conveyor frame 11 and to the adjusting plate 43. The limiting cylinder 42 is rotatably connected to the support column 41.

[0039] By moving the adjustment plate 43, the limiting cylinder 42 on one side is moved to the braking position, ensuring that the object to be tested is restricted by the limiting cylinders 42 on both sides when it moves, thereby achieving the effect of restricting the direction of movement of the object to be tested.

[0040] Reference Figure 1 , Figure 4 and Figure 5A fixed frame 12 and a movable frame 13 are arranged between two conveyor frames 11. A fixed base 14 is installed on the machine body 1, and the fixed frame 12 is mounted on the fixed base 14. An adjustment assembly 5 is provided on the machine body 1, which includes an adjustment motor 51, a connecting block 52, a limiting rail 53, and an adjustment screw 54. The adjustment screw 54 is rotatably connected to the fixed base 14, and the limiting rail 53 is installed on the fixed base 14 and parallel to the adjustment screw 54. The adjustment motor 51 is installed at one end of the fixed base 14 and coaxially connected to the adjustment screw 54. The movable frame 13 is slidably fitted on the limiting rail 53, and the connecting block 52 is fixedly connected to the movable frame 13. The adjustment screw 54 passes through the connecting block 52 and is threadedly engaged with the connecting block 52. Several support wheels 121 are installed on the opposite side walls of the fixed frame 12 and the movable frame 13, and the highest point of the support wheels 121 is flush with the surface of the conveyor belt 23.

[0041] When adjusting the position of the movable frame 13, the adjusting motor 51 is started, causing the adjusting screw 54 to rotate. Through the limiting rail 53 and the adjusting screw 54, the connecting block 52 moves, which drives the movable frame 13 to move, thereby achieving the effect of adjusting the position of the movable frame 13.

[0042] Reference Figure 4 Each fixed frame 12 is equipped with a rotating seat 122, and a roller 15 is mounted on the rotating seat 122. The top of the roller 15 is open, and a coupling fluid is placed inside the roller 15. In this embodiment, the coupling fluid is water. A coupling adhesive 151 is provided on the surface of the roller 15 to assist in the transmission of sound waves. A rotating component 152 is provided on the fixed frame 12. The rotating component 152 is a DC geared motor. The rotating component 152 is vertically arranged, and synchronous pulleys are mounted on both the rotating component 152 and the rotating seat 122. A synchronous belt is installed between the two synchronous pulleys. An ultrasonic probe 6 is mounted on the fixed frame 12 and is immersed in the coupling fluid. Similarly, the rotating component 152, the roller 15, and the ultrasonic probe 6 are arranged on the movable frame 13.

[0043] During testing, the rotating component 152 is activated, and the two rollers 15 rotate relative to each other. The moving test object passes between the two clamping rollers, and the coupling adhesive 151 squeezes and deforms the test object. At the same time, the ultrasonic probe 6 is used to detect the test object, thus achieving the effect of detecting the movement of the test object.

[0044] Reference Figure 4To improve the accuracy of the test object detection, several limiting wheels 123 are rotatably connected to the fixed frame 12 at the position corresponding to the top of the roller 15. This embodiment uses two as an example. The limiting wheels 123 abut against the surface of the roller 15. Similarly, limiting wheels 123 are set on the movable frame 13. The abutting wheels are used to limit the offset of the top of the roller 15. Mounting plates are installed on both the fixed frame 12 and the movable frame 13. The mounting plates are located between the conveyor frame 11 and the roller 15. Static eliminators 16 are installed on the mounting plates. In this embodiment, the static eliminator 16 is an static eliminator brush, and two static eliminators 16 are arranged opposite each other. The static eliminator 16 is used to remove static electricity from the surface of the test object, reducing interference to the detection equipment during detection.

[0045] The implementation principle of an ultrasonic rapid testing device with an automatic feeding structure according to an embodiment of this application is as follows: Before testing, the adjustment plate 43 is moved and locked with the locking bolt 44, so that the limiting cylinder 42 on one side moves to the designated position. Then, the adjustment motor 51 is started, so that the adjustment screw 54 rotates and the moving frame 13 moves, so that the roller 15 on the moving frame 13 moves to the braking position. During testing, the rotating part 152 and the conveyor motor 24 are started, so that the roller 15 rotates and the conveyor roller 21 rotates, driving the conveyor belt 23 to move. A batch of test objects are placed on the conveyor belt 23. The test objects move to the two rollers 15, the coupling adhesive 151 presses against the test objects, and the test objects move on the support wheel 121. At the same time, the ultrasonic probe 6 detects the test objects, so as to achieve the effect of automatic batch testing of the test objects.

[0046] By combining the conveying component 2 and the limiting component 4, the operator can place a batch of test objects at once and realize automatic conveying and testing of the test objects. Compared with the existing technology, this makes the testing equipment suitable for testing large batches of test objects and improves the applicability of the ultrasonic automatic testing equipment.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
