Abstract

This utility model discloses a nanocrystalline coil CCD inspection and positioning carrier, relating to the field of electrical component technology. The nanocrystalline coil CCD inspection and positioning carrier includes a base, a vacuum pump, a nanocrystalline coil positioning carrier, and a nanocrystalline coil positioning carrier groove. The base is equipped with four adaptive floating pressure plate assemblies. The arc-shaped floating pressure plates in the adaptive floating pressure plates can rotate slightly around a fixed rod, adapting to slight undulations or warping of the coil surface. Even if the coil has flatness errors, the "floating" characteristic can achieve uniform contact, avoiding coil damage caused by excessive local pressure. Simultaneously, the negative pressure generated by the adsorption plate adsorbs and fixes the coil from below, forming a "coordinated fixation" with the upward pressure of the floating pressure plates. This eliminates horizontal movement and vertical displacement of the coil during the inspection process, and prevents coil deformation due to rigid compression, significantly improving the stability and safety of the fixation.

Description

Technical Field

[0001] This utility model relates to the field of electrical component technology, and in particular to a nanocrystalline coil CCD inspection and positioning carrier. Background Technology

[0002] With the rapid development of technology, wireless charging technology has been increasingly widely used in the field of electronic devices. From smartphones and tablets to various smart home devices, the convenience of wireless charging is gradually changing people's usage habits. Nanocrystalline materials, with their excellent magnetic permeability and saturation magnetic induction intensity, have become key materials for wireless charging coils. In the wireless charging process, nanocrystalline coils need to achieve electromagnetic conversion efficiently, and their performance directly affects charging efficiency and stability. In order to ensure that nanocrystalline coils have good performance, quality inspection during the production process is crucial.

[0003] Among them, CCD (charge-coupled device) inspection technology plays an important role in the quality inspection of nanocrystalline coils due to its high-precision image acquisition and analysis capabilities. Through a CCD camera, the surface image of the nanocrystalline coil can be clearly acquired, and defects such as whether the number of coil turns is accurate, whether the wire diameter is uniform, whether there are scratches or breaks on the surface, and whether there are foreign objects inside can be detected. Accurate image acquisition depends on stable and precise positioning, which makes the nanocrystalline coil CCD inspection positioning carrier a key component of the entire inspection process. The positioning carrier must not only ensure that the nanocrystalline coil is fixed in position during the inspection process, but also ensure that it is in the optimal inspection position of the CCD camera to obtain clear and accurate image data.

[0004] Existing CCD inspection and positioning carriers for nanocrystalline coils mostly employ rigid fixing methods when securing the nanocrystalline coils. Common rigid fixing methods include using fixed-size positioning pins, which align specific holes of the nanocrystalline coil with the positioning pins to achieve preliminary position determination. However, due to manufacturing process limitations, the dimensions and surface flatness of nanocrystalline coils inevitably have certain errors during production. Even products from the same batch may have slight differences in the outer diameter, inner diameter, and thickness of the coil. Regarding surface flatness, the coil surface may exhibit slight undulations or warping. When using rigid positioning pins for positioning, if the coil's hole diameter does not perfectly match the positioning pin size, it may lead to difficulties in coil installation. Forced installation may also cause coil deformation, affecting its performance. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a nanocrystalline coil CCD inspection positioning carrier that can solve the problem that when using rigid positioning pins for positioning, if the diameter of the coil hole does not completely match the size of the positioning pin, it may lead to difficulties in coil installation, and forced installation may also cause the coil to deform, affecting its performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nanocrystalline coil CCD inspection and positioning carrier, comprising a base, a vacuum pump, a nanocrystalline coil positioning carrier and a nanocrystalline coil positioning carrier slide, wherein four adaptive floating pressure plate assemblies are provided on the base;

[0007] The adaptive floating pressure plate assembly includes a sliding column, an adjusting nut, a floating pressure plate, and a fixing rod. The outer walls of the four corner support blocks on the base are all provided with sliding column grooves, and the upper surfaces of the four corners of the base are all threaded with first fixing bolts. The upper surface of the sliding column is provided with multiple first fixing bolt grooves.

[0008] The outer wall of the fixed rod and the sliding column at the end away from the base are slidably connected by a groove. The adjusting nut is threaded to the upper outer wall of the fixed rod. The floating pressure plate at the end away from the base is sleeved on the outer wall of the fixed rod. The four adaptive floating pressure plate assemblies are correspondingly set at the four corners of the upper surface of the base and used in conjunction.

[0009] Preferably, the outer wall of the sliding column is slidably connected to the interior of the corresponding sliding column groove;

[0010] In this configuration, the threaded end of the first fixing bolt near the first fixing bolt groove extends into the interior of the sliding column groove and is connected to the internal thread of the corresponding first fixing bolt groove.

[0011] Preferably, the floating tablet is arc-shaped;

[0012] The lower surface of the adjusting nut contacts the upper surface of the floating pressure plate at the end furthest from the base.

[0013] Preferably, the upper surface of the base is provided with a nanocrystalline coil positioning carrier groove;

[0014] The nanocrystalline coil positioning carrier groove is equipped with an adsorption plate.

[0015] Preferably, the vacuum pump is fixedly installed on the outer wall of the front end of the base, and the outer wall of the nanocrystal coil positioning carrier is slidably connected to the inside of the nanocrystal coil positioning carrier groove.

[0016] The vacuum pump is connected to the adsorption disk via a connecting pipe.

[0017] Preferably, the outer wall of the nanocrystal coil positioning carrier has a groove that is slidably connected to the outer wall of the adsorption plate, and the nanocrystal coil positioning carrier has a positioning groove.

[0018] The adsorption disk is located inside the positioning groove on the nanocrystalline coil positioning carrier.

[0019] Preferably, the four sliding column grooves are located at the center of the four corner support blocks of the base.

[0020] Preferably, the connecting pipe is a negative pressure resistant flexible hose;

[0021] The connection points between the connecting pipe and the vacuum pump and the adsorption plate are all equipped with sealing joints.

[0022] Preferably, the shape of the positioning groove is consistent with the shape of the nanocrystalline coil.

[0023] Preferably, fixing plates are installed on both outer walls of the base, and four second fixing bolt slots are opened inside the slide groove of the nanocrystal coil positioning carrier, and four second fixing bolts are threadedly connected to the upper surface of the nanocrystal coil positioning carrier.

[0024] In this case, the end of the second fixing bolt near the second fixing bolt groove is threaded into the interior of the nanocrystalline coil positioning carrier slide groove and is respectively connected to the internal thread of the corresponding second fixing bolt groove.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. This nanocrystalline coil CCD inspection positioning carrier, through the adaptive floating pressure plate, can slightly rotate around the fixed rod, adapting to slight undulations or warping of the coil surface. Even if the coil has flatness errors, it can achieve uniform fit through the "floating" characteristic, avoiding coil damage caused by excessive local pressure.

This not only eliminates horizontal movement and vertical displacement of the coil during the detection process, but also prevents coil deformation due to rigid compression, significantly improving the stability and safety of the fixation.

[0037] Please see Figure 1-4 This utility model provides a technical solution: a nanocrystalline coil CCD inspection and positioning carrier, including a base 1, a vacuum pump 2, a nanocrystalline coil positioning carrier 7 and a nanocrystalline coil positioning carrier slide 13;

[0038] Four adaptive floating tablet compression assemblies are provided on the base 1;

[0039] The adaptive floating pressure plate assembly includes a sliding column 3, an adjusting nut 4, a floating pressure plate 5, and a fixing rod 6. The outer walls of the four corner support blocks on the base 1 are each provided with a sliding column groove 12. The outer wall of the sliding column 3 is slidably connected to the interior of the corresponding sliding column groove 12. The upper surfaces of the four corners of the base 1 are each threaded with a first fixing bolt 10. The upper surface of the sliding column 3 is provided with multiple first fixing bolt grooves 9. The end of the first fixing bolt 10 closest to the first fixing bolt groove 9 extends threadedly into the interior of the sliding column groove 12 and is threadedly connected to the interior of the corresponding first fixing bolt groove 9. The floating pressure plate 5 is arc-shaped. The outer wall of the fixing rod 6 is slidably connected to the inner groove of the sliding column 3 at the end away from the base 1. The adjusting nut 4 is threadedly connected to the upper outer wall of the fixing rod 6. The end of the floating pressure plate 5 away from the base 1 is sleeved on the outer wall of the fixing rod 6. The lower surface of the adjusting nut 4 contacts the upper surface of the floating pressure plate 5 at the end away from the base 1. The four adaptive floating pressure plate assemblies are correspondingly arranged at the four corners of the upper surface of the base 1 and work together.

[0040] The base 1 has a nanocrystal coil positioning carrier groove 13 on its upper surface. An adsorption plate 8 is installed inside the nanocrystal coil positioning carrier groove 13. A vacuum pump 2 is fixedly installed on the outer wall of the front end of the base 1. The outer wall of the nanocrystal coil positioning carrier 7 is slidably connected to the inside of the nanocrystal coil positioning carrier groove 13. The vacuum pump 2 is connected to the adsorption plate 8 through a connecting pipe. The outer wall of the nanocrystal coil positioning carrier 7 has a groove that is slidably connected to the outer wall of the adsorption plate 8. The nanocrystal coil positioning carrier 7 has a positioning groove. The adsorption plate 8 is located inside the positioning groove on the nanocrystal coil positioning carrier 7. The inside of the nanocrystal coil positioning carrier groove 13 has four second fixing bolt grooves 14. The upper surface of the nanocrystal coil positioning carrier 7 is threaded with four second fixing bolts 11. The ends of the four second fixing bolts 11 near the second fixing bolt grooves 14 are all threaded into the inside of the nanocrystal coil positioning carrier groove 13 and are respectively threaded into the corresponding second fixing bolt grooves 14.

[0041] Furthermore, when using this device, firstly, adjust the length of the sliding column 3 according to the size (length, diameter) of the nanocrystalline coil to be tested, loosen the first fixing bolt 10, and move the sliding column 3 back and forth along the sliding column groove 12 so that one end of the floating pressure plate 5 is adapted to the coil. Once the length is determined, screw the first fixing bolt 10 into the first fixing bolt groove 9 of the corresponding length to lock the position of the sliding column 3. Then, move the fixing rod 6 up and down along the groove of the sliding column 3 so that the arc-shaped part of the floating pressure plate 5 is aligned with the edge of the coil. Rotate the adjusting nut 4 to press the lower surface of the adjusting nut 4 against the coil. At the end of the moving pressure plate 5, ensure that the floating pressure plate 5 can rotate slightly around the fixed rod 6 (retaining a "floating" margin). Then, place the nanocrystalline coil in the positioning groove of the nanocrystalline coil positioning carrier 7. The positioning groove restricts the horizontal displacement of the coil through shape matching, pushing the nanocrystalline coil positioning carrier 7 to slide along the nanocrystalline coil positioning carrier slide groove 13 to the detection station. At this time, the adsorption plate 8 is exactly located in the positioning groove and in contact with the lower surface of the coil. Then, start the vacuum pump 2. The vacuum pump 2 draws air from the adsorption plate 8 through the connecting pipe, creating a negative pressure on the surface of the adsorption plate 8. The pressure is applied through the contact surface between the coil and the adsorption plate 8 to apply a downward adsorption force to the coil, initially fixing the coil in the positioning groove and preventing the coil from moving horizontally. Then, under the pressure of the adjusting nut 4, the lower ends of the arc-shaped floating pressure plates 5 of the four adaptive floating pressure plate assemblies are attached to the edge of the upper surface of the coil. Because the floating pressure plates 5 can rotate slightly around the fixing rod 6 ("floating" characteristic), even if there is slight warping or unevenness on the coil surface, the floating pressure plates 5 can adaptively fit the coil surface, avoiding excessive local pressure that could damage the coil. In this way, the floating pressure plates 5 at the four corners cooperate... The function is to apply uniform downward pressure from all sides of the coil, which, together with the negative pressure adsorption of the adsorption plate 8, forms a "coordinated fixation from top to bottom", ensuring that the coil is completely stationary during the detection process, providing a stable detection target for the CCD camera. After the coil is fixed, the CCD camera performs image acquisition and defect detection on the coil. After the detection is completed, the vacuum pump 2 is turned off, the negative pressure of the adsorption plate 8 disappears, the adjusting nut 4 is rotated in the opposite direction to release the coil from the floating pressure plate 5, and the nanocrystalline coil positioning carrier 7 slides out along the nanocrystalline coil positioning carrier slide groove 13. The coil that has been detected is removed, completing one detection cycle.

[0042] The arc-shaped floating pressure plate 5 in the adaptive floating pressure plate can rotate slightly around the fixed rod 6, which can adapt to the slight undulations or warping of the coil surface. Even if there is a flatness error in the coil, it can achieve uniform fit through the "floating" characteristic, avoiding coil damage caused by excessive local pressure. At the same time, the negative pressure generated by the suction plate 8 adsorbs and fixes the coil from below, forming a "top-bottom coordinated fixation" with the pressure above the floating pressure plate 5. This not only eliminates the horizontal movement and vertical displacement of the coil during the testing process, but also prevents the coil from deforming due to rigid compression, significantly improving the stability and safety of the fixation.

[0043] Structural Description: Base 1: As the basic support component of the entire device, support blocks are provided at the four corners of the upper surface. Sliding column grooves 12 are opened on the outer wall of the support blocks (for installing sliding columns 3). First fixing bolts 10 are threaded to the four corners of the upper surface (for fixing the position of sliding columns 3). At the same time, a nanocrystalline coil positioning carrier groove 13 is opened on the upper surface of the base 1 (to provide a sliding track for the nanocrystalline coil positioning carrier 7). A vacuum pump 2 is fixedly installed on the front outer wall. The whole provides an installation reference and structural support for each component.

[0044] Vacuum pump 2: It is fixedly installed on the outer wall of the front end of the base 1 and connected to the adsorption plate 8 through the connecting pipe. Its core function is to generate negative pressure on the adsorption plate 8 by pumping air, so as to achieve vacuum adsorption and fixation of the nanocrystal coil in conjunction with the nanocrystal coil positioning carrier 7.

[0045] Sliding column 3: The outer wall is slidably connected to the sliding column groove 12 of the four corner support blocks of the base 1. It can move up and down along the sliding column groove 12 to adjust the length. Multiple first fixing bolt grooves 9 (distributed along the length direction) are opened on the upper surface. The position is locked by cooperating with the first fixing bolt 10. A groove is opened at the end away from the base 1 (for installing the fixing rod 6).

[0046] Adjusting nut 4: It is threaded to the upper outer wall of the fixing rod 6, and its lower surface is in contact with the upper surface of the floating pressure plate 5 away from the base 1. By rotating and adjusting, the pressure on the floating pressure plate 5 can be changed, thereby adjusting the tightness of the floating pressure plate 5.

[0047] Floating pressure plate 5: It is arc-shaped (to fit the arc edge of the nanocrystalline coil and improve the fit). The end away from the base 1 is sleeved on the outer wall of the fixing rod 6. It can rotate slightly around the fixing rod 6 to adapt to the unevenness of the coil surface and achieve the "floating" pressing effect.

[0048] Fixed rod 6: The outer wall is slidably connected to the groove at the end of the sliding column 3 away from the base 1. It can move up and down along the groove to adjust the length of the floating pressure plate 5. The upper end is locked by the adjusting nut 4 to lock the position of the floating pressure plate 5, and the lower end provides a mounting point for the floating pressure plate 5.

[0049] Nanocrystal coil positioning carrier 7: The outer wall is slidably connected to the inside of the nanocrystal coil positioning carrier slide groove 13, and can enter and exit the detection station along the nanocrystal coil positioning carrier slide groove 13. The upper surface is provided with a positioning groove (used to place the nanocrystal coil and limit the horizontal displacement of the coil). The outer wall is provided with a groove and is slidably connected to the outer wall of the adsorption plate 8 (to ensure that the adsorption plate 8 and the positioning groove are precisely aligned), which is the direct bearing component of the coil.

[0050] Adsorption plate 8: Installed inside the slide groove 13 of the nanocrystalline coil positioning carrier, located in the positioning groove on the nanocrystalline coil positioning carrier 7, and connected to the vacuum pump 2 through a connecting pipe. Its surface is covered with tiny air holes. When the vacuum pump 2 is working, the air holes generate negative pressure, adsorbing and fixing the nanocrystalline coil in the positioning groove to prevent the coil from moving during the detection process.

[0051] Sliding column groove 12: It is formed on the outer wall of the four corner support blocks of the base 1 and is slidably connected to the outer wall of the sliding column 3. It provides guidance for the up and down movement of the sliding column 3 and ensures that the sliding column 3 is stably adjusted in the vertical direction.

[0052] Nanocrystal coil positioning carrier slide 13: It is formed on the upper surface of the base 1 and is slidably connected to the outer wall of the nanocrystal coil positioning carrier 7. It also accommodates the adsorption plate 8 and provides a track for the nanocrystal coil positioning carrier 7 to enter and exit, ensuring the straightness and stability of the carrier when it moves.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
