Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal thin film detection technology, and in particular to an X-ray detection mechanism for metal thin films of thin film capacitors. Background Technology
[0002] In the production process of capacitors, metallized polypropylene film is generally used as the electrode of film capacitors to improve the stability of its electrodes. After the metallized polypropylene film is manufactured and formed, it needs to be analyzed and tested by an X-ray inspection agency to ensure that its surface quality meets the usage requirements and to facilitate the adjustment of the production process that affects these properties.
[0003] To facilitate storage, metal films are typically rolled up. However, prolonged rolling can cause significant bending of the metal film, resulting in a bent shape when the metal film sample is cut. Before testing, users need to manually smooth the metal film while using clamps to secure the smoothed portion, making the sample fixing process cumbersome and inefficient. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose an X-ray detection mechanism for metal thin films of thin film capacitors, so as to solve the problem that the manual fixation operation of metal thin film samples is cumbersome and relatively inefficient.
[0005] To achieve the above objectives, this utility model provides an X-ray inspection mechanism for a thin-film capacitor metal film, including an inspection stage and a support frame fixedly disposed on the top of the inspection stage. The X-ray inspection mechanism also includes a screw rod that is threadedly connected to a screw hole disposed on the top of the support frame, and a support plate is fixedly disposed at the bottom end of the screw rod.
[0006] A drive unit used to drive the screw to rise and fall.
[0007] Two diagonal bracing arms are hinged to the bottom of the support plate.
[0008] The smoothing rod, fixed at the bottom of the inclined arm, is driven by the drive screw to descend, causing the two inclined arms to deflect synchronously and move their bottom ends away from each other. This synchronously pushes the two smoothing rods to move and smooth the metal film from the middle to both sides.
[0009] An elastic guide is horizontally positioned between two diagonal bracing arms. The elastic guide is used to provide vertical compressive force after the metal film is flattened, so that the diagonal bracing arms flatten and fix the metal film to the top of the testing table.
[0010] Preferably, the X-ray detection mechanism further includes an X-ray detection module, which includes a low-energy X-ray source fixedly disposed at the bottom of the support plate and a flat panel detector embedded in the top of the detection table. The flat panel detector is used to receive the intensity of transmitted X-rays at various parts of the X-ray working surface.
[0011] Preferably, the length of the smoothing rod is less than the distance between the relative vertical surfaces within the support frame, and the length of the flat panel detector in the plane perpendicular to the moving direction of the two smoothing rods is less than the length of the smoothing rod.
[0012] Preferably, the elastic guide includes sliders respectively rotatably mounted on vertical surfaces flush with each other on two inclined support arms, a guide rod transversely inserted between the two sliders, and compression springs respectively fitted at both ends of the guide rod, with one end of the compression spring fixedly disposed on one end outside the guide rod.
[0013] Preferably, the elastic guide further includes two limiting plates axially fixed to the guide rod, and the slider is located between the compression spring and the limiting plates in the axial direction of the guide rod.
[0014] Preferably, the two limiting pieces are located between the two sliders in the axial direction of the guide rod, and the distance between the opposite surfaces of the two limiting pieces is greater than the distance between the top ends of the two diagonal braces.
[0015] Preferably, the drive unit includes two guide holes located opposite each other on the top of the support frame, with a vertical rod inserted through the guide holes. The bottom of the vertical rod is fixed to the top of the support plate, and a horizontal support plate is fixed between the tops of the two vertical rods. A motor is located on the top of the horizontal support plate, and the top of the screw passes upward through the top of the horizontal support plate and is fixed to the output end of the motor.
[0016] Preferably, the screw is located between two vertical rods, and the two vertical rods and the horizontal support plate together form an inverted U-shaped frame.
[0017] The beneficial effects of this utility model are:
[0018] This invention places a bent metal film between two smoothing rods and a flat panel detector. Then, the drive unit rotates and lowers the screw, which pushes the support plate and the diagonal brace arm to descend synchronously. After the two smoothing rods press the metal film against the flat panel detector, the screw continues to descend, pushing the free ends of the two diagonal brace arms away from each other and causing the two smoothing rods to move synchronously. At the same time, the slider pushes the compression spring to compress and accumulate elastic force until the smoothing rods are disengaged from the flat panel detector. Then, the drive unit stops, realizing the simultaneous smoothing and fixing of the metal film, thus improving the efficiency of smoothing and fixing the metal film. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 4 As shown, an X-ray inspection mechanism for a thin-film capacitor metal film includes an inspection stage 1 and a support frame 2 fixedly disposed on the top of the inspection stage 1. The support frame 2 is in the shape of an inverted U. The X-ray inspection mechanism also includes a screw 3 that is threadedly connected to a screw hole 10 disposed on the top of the support frame 2. A support plate 5 is fixedly disposed at the bottom end of the screw 3.
[0029] Drive unit 4 for driving the screw 3 to rise and fall.
[0030] Two diagonal bracing arms 6 are hinged to the bottom of the support plate 5.
[0031] The smoothing rod 7, which is fixed at the bottom of the inclined support arm 6, is driven by the drive screw 3 of the drive unit 4 to descend, causing the two inclined support arms 6 to deflect synchronously and move their bottom ends away from each other. This synchronously pushes the two smoothing rods 7 to move and smooth the metal film from the middle to both sides.
[0032] An elastic guide 8 is horizontally positioned between two diagonal bracing arms 6. The elastic guide 8 is used to provide vertical extrusion force after the metal film is smoothed, so that the diagonal bracing arms 6 flatten and fix the metal film on the top of the testing table 1. In this way, the smoothing and fixing operations of the metal film can be completed simultaneously before testing, thereby improving the smoothing and fixing efficiency of the metal film.
[0033] like Figures 1 to 3 As shown, the X-ray detection mechanism also includes an X-ray detection module 9. The X-ray detection module 9 includes a low-energy X-ray source 92 fixedly mounted on the bottom of the support plate 5 and a flat panel detector 91 embedded on the top of the detection table 1. The flat panel detector 91 is electrically connected to the information processing module through wires, so that various detection data can be obtained. A metal film is placed between the bottom of the low-energy X-ray source 92 and the top of the flat panel detector 91. The flat panel detector 91 is used to receive the intensity of transmitted X-rays at various parts of the X-ray working surface.
[0034] The length of the smoothing rod 7 is less than the distance between the relative vertical surfaces within the support frame 2, and the length of the flat plate detector 91 in the plane perpendicular to the moving direction of the two smoothing rods 7 is less than the length of the smoothing rod 7.
[0035] This design allows the two diagonal bracing arms 6 to extend laterally and smooth the metal film on the top of the flat panel detector 91, so that the metal film completely covers the top of the flat panel detector 91. The flat panel detector 91 receives the intensity of transmitted X-rays at various points on the metal film on its top, thus enabling the analysis of the elemental composition, compositional uniformity, and chemical state of the metal film surface.
[0036] like Figures 2 to 4As shown, the elastic guide 8 includes sliders 81 that are rotatably mounted on vertical surfaces that are flush with each other on two inclined support arms 6. A guide rod 82 is transversely inserted between the two sliders 81. A compression spring 84 is sleeved on both ends of the guide rod 82. One end of the compression spring 84 is fixed to one end of the guide rod 82.
[0037] The elastic guide 8 also includes two limiting pieces 83 that are axially fixed to the guide rod 82, and the slider 81 is located between the compression spring 84 and the limiting pieces 83 in the axial direction of the guide rod 82.
[0038] Two limiting pieces 83 are located between two sliders 81 in the axial direction of the guide rod 82, and the distance between the opposite surfaces of the two limiting pieces 83 is greater than the distance between the top ends of the two diagonal braces 6.
[0039] As the screw 3 descends, it pushes the two inclined arms 6 to deflect, causing their bottom ends to move away from each other. This pushes the two smoothing rods 7 to move synchronously. As the angle between the two inclined arms 6 increases, it pushes the two sliders 81 to move away from each other and compresses the spring 84 to elastically deform and contract. After the metal film completely covers the top of the flat panel detector 91, the drive unit 4 stops. Under the elastic force of the spring 84, the two inclined arms 6 maintain a stable static state and apply pressure to the metal film at their bottom ends, thus squeezing and fixing the metal film. This achieves synchronous smoothing and fixing of the metal film, improving the fixing efficiency of the metal film.
[0040] like Figure 4 As shown, the drive unit 4 includes two guide holes 41 located opposite each other on the top of the support frame 2. A vertical rod 42 is inserted into the guide hole 41. The bottom of the vertical rod 42 is fixed to the top of the support plate 5. A horizontal support plate 43 is fixed between the tops of the two vertical rods 42. A motor 44 is located on the top of the horizontal support plate 43. The top of the screw 3 passes upward through the top of the horizontal support plate 43 and is fixed to the output end of the motor 44.
[0041] The screw 3 is located between the two vertical rods 42, and the two vertical rods 42 and the horizontal support plate 43 together form an inverted U-shaped frame. With this design, the lifting and lowering action of the screw 3 can be achieved by controlling the rotation of the output end of the motor 44. In conjunction with the inverted U-shaped frame, the stability of the synchronous lifting and lowering of the motor 44 and the screw 3 is improved.
[0042] Working principle: First, place the metal film on top of the flat panel detector 91, aligning the centerline of the metal film with the centerline of the flat panel detector 91 in the direction of movement of the two smoothing rods 7. Then, operate the motor 44 to drive the screw 3 to rotate and descend. The screw 3 pushes the support plate 5 to descend synchronously, driving the motor 44 and the inverted U-shaped frame to descend synchronously, causing the two smoothing rods 7 to move down and press the metal film onto the top of the flat panel detector 91. At the same time, as the screw 3 continues to descend, the two diagonal bracing arms 6 deflect synchronously and their bottom ends move away from each other, synchronously pushing the two smoothing rods 7 to move synchronously. The metal film is smoothed from the middle to both sides until the smoothed area covers the top of the flat panel detector 91. During the smoothing process, when the angle between the two inclined support arms 6 increases, the two sliders 81 are pushed away from each other and the compression spring 84 is squeezed and deformed, so that part of the elastic force on the compression spring 84 is converted into vertical compression force. In this way, the metal film can be flattened and fixed at the same time as it is smoothed, so that the two are carried out and finished simultaneously, improving the metal film fixing efficiency. After the metal film is fixed, subsequent X-ray detection can be performed.
