Description

Technical Field

[0001] This invention relates to the field of tooling and mold technology for gold spraying of thin film capacitors, and in particular to a tooling for arranging electrodes for double-sided attachment of thin film capacitor cores. Background Technology

[0002] Electric vehicle film capacitor cores are electronic components used in electric vehicles (especially in the drive systems and energy recovery systems of new energy vehicles). They are made using organic thin films (such as polypropylene and polyester) as the dielectric and metallized thin film layers as electrodes, through winding and encapsulation methods. They have characteristics such as high voltage resistance, low loss, high ripple current withstand capability, and long life. They are mainly used for DC support, filtering, energy storage and release, and are one of the key components to ensure the stable operation of electric vehicle power electronic systems. With the rapid development of the new energy vehicle industry, film capacitors for electric vehicles, as core components of power electronic systems, directly affect the reliability of the entire vehicle drive system in terms of performance stability and production efficiency. In the manufacturing process of film capacitor cores, the double-sided electrode attachment process is a key step in forming the electrode leads. By spraying metal layers on both ends of the capacitor core, a reliable connection between the electrodes and the external circuit is achieved. This process places extremely high demands on the positioning accuracy, arrangement stability, and tooling operation convenience of the core.

[0003] In existing technologies, most tooling uses simple slots or clamping structures. During the gold spraying process, the high-speed sprayed metal powder can easily cause slight displacement or deflection of the core, resulting in uneven thickness of the gold spraying layer at both ends and incomplete edge coverage, which in turn affects the voltage withstand performance and electrical connection reliability of the capacitor. On the other hand, if too many structures are used to fix and limit the core, on the one hand, the assembly difficulty will be high, which will reduce work efficiency, and on the other hand, it will affect the gold spraying position of each core and block the gold spraying area, which will also reduce the spraying effect. In view of this, the present invention is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a tooling for arranging electrodes on both sides of a thin-film capacitor core.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixture for arranging electrodes on both sides of a thin-film capacitor core includes a square frame and further includes: Multiple horizontal plates are detachably connected to the square frame. Capacitor core bodies are provided between the multiple horizontal plates and between the horizontal plates and the upper and lower inner walls of the square frame. Each horizontal plate is provided with multiple grooves. Multiple elastic limiting members are provided, and one elastic limiting member is correspondingly provided in each of the grooves; An adjusting rod is slidably mounted on the horizontal plate. When the adjusting rod moves inward into the horizontal plate, it will cause the elastic limiting member to abut against the capacitor core body.

[0006] Preferably, a screw is connected to one end of the elastic limiting member, and the one end of the elastic limiting member is fixedly connected to the inner wall of the groove by the screw. The end of the elastic limiting member away from the screw is set as an open end.

[0007] Furthermore, a threaded cylinder is rotatably connected to the adjusting rod, and a cone block is fixedly provided on the outer wall of the threaded cylinder. The cone block is disposed between the elastic limiting members. When the cone block moves towards the side closer to the screw, it will increase the opening end of the elastic limiting member.

[0008] Furthermore, the elastic limiting member is provided with an inclined section and a horizontal section corresponding to the capacitor core body, and both the upper and lower ends of the cone are set as inclined surfaces, with the inclined surfaces on the cone abutting against the inner wall of the inclined section on the elastic limiting member.

[0009] Furthermore, a circular block is threaded onto the adjusting rod, a circular plate is fixedly mounted on the circular block, a limit block is fixedly mounted on the outer wall of the circular plate, and an arc-shaped block is fixedly mounted on the outer wall of the square frame, with a limit groove corresponding to the limit block on the arc-shaped block.

[0010] Furthermore, a knob is fixedly installed on one end of the adjusting rod outside the square frame. When the adjusting rod rotates, the circular block is limited by the limiting block and the limiting groove, thereby allowing the adjusting rod to move.

[0011] Preferably, the square frame is provided with T-slots on both sides, the horizontal plate is provided with T-blocks on both sides, the T-blocks are slidably connected in the T-slots, and one side of the square frame is also provided with a long groove that communicates with the T-slots, and the adjusting rod is slidably connected in the long groove.

[0012] Preferably, a first sealing strip is fixedly provided on the square frame.

[0013] Furthermore, bolts and a second sealing strip are connected to the outer wall of the horizontal plate. The second sealing strip is connected to the horizontal plate by bolts. A shallow groove is provided on the back of the square frame. The second sealing strip is placed in the shallow groove. A folded edge is provided on the second sealing strip. The folded edge is wrapped around the square frame.

[0014] Preferably, the top of the square frame is provided with a hook and a label slot, and a cover plate is attached to the top of the square frame. The cover plate is provided with a through slot corresponding to the hook, and the hook passes through the through slot and extends outward.

[0015] Compared with the prior art, the present invention provides an arrangement tooling for attaching electrodes on both sides of a thin-film capacitor core, which has the following advantages: 1. The electrode attachment fixture for the thin-film capacitor core involves mounting multiple capacitor core bodies on a square frame. Rotating the adjusting rod causes the threaded cylinder and cone to move. The inclined surface of the cone contacts the inclined section of the elastic limiting member. As the cone continues to advance, it expands the elastic limiting member, causing it to deform. Consequently, the horizontal section of the elastic limiting member opens, thus abutting against the upper and lower ends of the capacitor core body, thereby fixing the capacitor core body and ensuring greater stability during electrode attachment.

[0016] 2. The electrode arrangement fixture attached to the film capacitor core allows for simultaneous installation of the adjusting rod when the horizontal plate is installed. At the same time, the limiting block on the circular plate connected to the adjusting rod is inserted into the limiting groove on the arc-shaped block. When the adjusting rod is rotated, the circular block will not rotate with the adjusting rod. Therefore, the adjusting rod can stably connect with the circular block by a thread and begin to move, thereby pushing the cone block connected to the adjusting rod to move and completing the limiting effect of the elastic limiting component.

[0017] 3. The electrode arrangement fixture for the thin-film capacitor core, through optimized arrangement and limiting structure, achieves stable clamping of the thin-film capacitor core, effectively avoiding displacement or deflection of the core caused by high-speed metal powder impact during the gold spraying process, ensuring uniform thickness of the gold spraying layer at both ends and complete edge coverage, significantly improving the voltage withstand performance and electrical connection reliability of the capacitor, and reducing the product scrap rate.

[0018] 4. The electrode arrangement fixture for the thin-film capacitor core simplifies the fixed limiting structure while ensuring the positioning accuracy of the core. It avoids the obstruction of the gold spraying area by too many complex parts, ensuring that the gold spraying powder can fully cover the end face of the core, improving the uniformity and adhesion of the spraying. At the same time, it simplifies the core assembly and disassembly process, reduces the assembly difficulty, greatly improves the efficiency of mass production, and avoids the extension of production cycle due to structural redundancy.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] Example 1: Refer to Figures 1-9A fixture for arranging electrodes on both sides of a thin-film capacitor core includes a square frame 1 and multiple horizontal plates 2 detachably connected to the square frame 1. Capacitor core bodies 206 are provided between the multiple horizontal plates 2 and between the horizontal plates 2 and the upper and lower inner walls of the square frame 1, and each horizontal plate 2 is provided with multiple grooves 201; multiple elastic limiting members 202 are provided, and each groove 201 is provided with a corresponding elastic limiting member 202; an adjusting rod 3 is slidably disposed on the horizontal plate 2, and when the adjusting rod 3 moves into the horizontal plate 2, the elastic limiting member 202 will abut against the capacitor core body 206.

[0024] In this embodiment, when installing multiple capacitor core bodies 206 into the interior of the square frame 1, the square frame 1 is first placed flat on a table or work surface with its front facing down. Then, multiple horizontal plates 2 are installed on the square frame 1. Since the horizontal plates 2 are detachably connected, installation and disassembly are convenient. For the first use, the horizontal plates 2 can be installed directly; subsequently, they do not need to be disassembled, only the capacitor core bodies 206 need to be replaced. After the horizontal plates 2 are installed, multiple capacitor core bodies 206 are placed sequentially between adjacent horizontal plates 2, with the top row of capacitor core bodies 206 placed between the horizontal plates 2 and... Similarly, between the top inner walls of the square frame 1, the bottom row of capacitor core bodies 206 are placed between the horizontal plate 2 and the bottom inner wall of the square frame 1, and each capacitor core body 206 is in contact with the elastic limiting member 202. When it is necessary to fix it after placement, the control adjustment rod 3 moves inward to the horizontal plate 2, thereby pushing the elastic limiting member 202 on the horizontal plate 2 to deform, so that the elastic limiting member 202 and the capacitor core body 206 are tightly abutted, thereby completing the fixation of the capacitor core body 206. Then the entire square frame 1 is placed into the electrode attachment device for electrode attachment operation.

[0025] Furthermore, when the electrode attachment is completed and disassembly is required, the control adjustment rod 3 moves in the opposite direction, thereby allowing the elastic limiting member 202 to automatically reset and lose its restriction on the capacitor core body 206. This allows the capacitor core body 206 to be easily removed without disassembling the horizontal plate 2. A new, unpainted capacitor core body 206 can be directly replaced and installed inside the square frame 1. The new capacitor core body 206 can then be painted again. Through simple fixing, multiple capacitor core bodies 206 can be limited, making the operation convenient and without affecting the painting area. At the same time, it can prevent slight displacement or deflection of the capacitor core body 206 during the painting process, which would affect the gold spraying effect, improve the uniformity of the spraying, and ensure the subsequent use effect.

[0026] Example 2: Refer to Figures 1-9A fixture for arranging electrodes on both sides of a thin-film capacitor core includes a square frame 1 and multiple horizontal plates 2 detachably connected to the square frame 1. Capacitor core bodies 206 are provided between the multiple horizontal plates 2 and between the horizontal plates 2 and the upper and lower inner walls of the square frame 1, and each horizontal plate 2 is provided with multiple grooves 201; multiple elastic limiting members 202 are provided, and each groove 201 is provided with a corresponding elastic limiting member 202; an adjusting rod 3 is slidably disposed on the horizontal plate 2, and when the adjusting rod 3 moves into the horizontal plate 2, the elastic limiting member 202 will abut against the capacitor core body 206.

[0027] Reference Figures 5-8 Furthermore, a screw 205 is connected to one end of the elastic limiting member 202, and one end of the elastic limiting member 202 is fixedly connected to the inner wall of the groove 201 by the screw 205. The end of the elastic limiting member 202 away from the screw 205 is set as an open end.

[0028] Reference Figures 5-8 A threaded cylinder 302 is rotatably connected to the adjusting rod 3. A cone block 303 is fixedly installed on the outer wall of the threaded cylinder 302. The cone block 303 is located between the elastic limiting members 202. When the cone block 303 moves to the side closer to the screw 205, it will increase the opening end of the elastic limiting member 202.

[0029] Reference Figures 6-8 The elastic limiting member 202 is provided with an inclined section 203 and a horizontal section 204 corresponding to the capacitor core body 206. Both the upper and lower ends of the cone block 303 are set as inclined surfaces, and the inclined surfaces on the cone block 303 abut against the inner wall of the inclined section 203 on the elastic limiting member 202.

[0030] In this embodiment, after the multiple capacitor core bodies 206 are mounted on the square frame 1, the adjusting rod 3 is rotated, causing the adjusting rod 3 to move the threaded cylinder 302 and the cone block 303. It should be noted that the threaded cylinder 302 is rotatably mounted on the outer wall of the adjusting rod 3. It can rotate on the threaded cylinder 302, but it will not move left or right on the adjusting rod 3. That is, when the adjusting rod 3 rotates, it will not cause the threaded cylinder 302 to rotate as well; however, when the adjusting rod 3 moves, it can move the threaded cylinder 302. As it moves, the cone 303 moves, and the inclined surface on the cone 303 comes into contact with the inclined section 203 on the elastic limiting member 202. As the cone 303 continues to advance, it will open the elastic limiting member 202, causing the elastic limiting member 202 to deform. As a result, the horizontal section 204 on the elastic limiting member 202 will open, thereby abutting against the capacitor core body 206 at both ends, thus fixing the capacitor core body 206 and making it more stable during electrode attachment operation.

[0031] Reference Figures 5-9A circular block 304 is threaded onto the adjusting rod 3. A circular plate 305 is fixedly mounted on the circular block 304. A limit block 306 is fixedly mounted on the outer wall of the circular plate 305. An arc-shaped block 4 is fixedly mounted on the outer wall of the square frame 1. A limit groove 401 corresponding to the limit block 306 is provided on the arc-shaped block 4.

[0032] Reference Figures 5-9 A knob 301 is fixedly installed on one end of the adjusting rod 3 outside the square frame 1. When the adjusting rod 3 rotates, the round block 304 is limited by the limiting block 306 and the limiting groove 401, so that the adjusting rod 3 can move.

[0033] In this embodiment, when the horizontal plate 2 is installed, the adjusting rod 3 is also installed simultaneously. At the same time, the limiting block 306 on the circular plate 305 connected to the adjusting rod 3 is inserted into the limiting groove 401 on the arc-shaped block 4. Since the position of the arc-shaped block 4 is fixed, and the limiting block 306 and the limiting groove 401 are fixed, the position of the circular block 304 connected to the circular plate 305 is fixed. When the adjusting rod 3 is rotated, the circular block 304 will not rotate with the adjusting rod 3. Therefore, the adjusting rod 3 can be stably threadedly connected to the circular block 304, so the adjusting rod 3 can start to move, thereby pushing the cone block 303 connected to the adjusting rod 3 to move, completing the limiting effect of the elastic limiting member 202. The cone block 303 is rotatably connected to the adjusting rod 3 and will not affect the movement of the adjusting rod 3.

[0034] It should also be noted that when the adjusting rod 3 in this application is installed, the limiting block 306 on the circular plate 305 will be directly inserted into the limiting groove 401 on the arc-shaped block 4 to achieve the limiting effect. No additional operation is required, and the overall operation is simple and convenient.

[0035] Example 3: Refer to Figures 1-9 A fixture for arranging electrodes on both sides of a thin-film capacitor core includes a square frame 1 and multiple horizontal plates 2 detachably connected to the square frame 1. Capacitor core bodies 206 are provided between the multiple horizontal plates 2 and between the horizontal plates 2 and the upper and lower inner walls of the square frame 1. Each horizontal plate 2 has multiple grooves 201. Multiple elastic limiting members 202 are provided, with one elastic limiting member 202 corresponding to each groove 201. An adjusting rod 3 is slidably disposed on the horizontal plate 2. When the adjusting rod 3 moves inward into the horizontal plate 2, the elastic limiting member 202 abuts against the capacitor core body 206. Similar to Embodiment 2, but further, T-shaped grooves 103 are provided on both sides of the square frame 1, and T-shaped blocks 207 are provided on both sides of the horizontal plate 2. The T-shaped blocks 207 are slidably connected within the T-shaped grooves 103. One side of the square frame 1 also has a long groove 104 communicating with the T-shaped grooves 103, and the adjusting rod 3 is slidably connected within the long groove 104.

[0036] In this embodiment, when installing the horizontal plate 2, the T-shaped blocks 207 at both ends of the horizontal plate 2 are directly inserted into the T-shaped grooves 103 on the square frame 1, and the adjusting rod 3 is inserted into the long groove 104, thereby limiting the circular plate 305 connected to the adjusting rod 3 and the arc-shaped block 4.

[0037] Reference Figures 1-6 A first sealing strip 102 is fixedly installed on the square frame 1. The first sealing strip 102 is located on the front of the square frame 1, and the positions of the multiple horizontal plates 2 correspond to the positions of the first sealing strip 102. When installing the capacitor core body 206, the front of the square frame 1 is first placed downwards, and then the capacitor core body 206 is placed between the multiple horizontal plates 2. At the same time, the first sealing strip 102 will support the capacitor core body 206 to prevent the capacitor core body 206 from falling off the other end of the square frame 1.

[0038] Reference Figures 1-6 Bolts 209 and a second sealing strip 208 are connected to the outer wall of the horizontal plate 2. The second sealing strip 208 is connected to the horizontal plate 2 by bolts 209. A shallow groove 101 is provided on the back of the square frame 1. The second sealing strip 208 is set in the shallow groove 101. A folded edge 210 is provided on the second sealing strip 208. The folded edge 210 is wrapped around the square frame 1.

[0039] In this embodiment, after the capacitor core body 206 is placed, a second sealing strip 208 is connected to the horizontal plate 2 and then fixed with bolts 209. The second sealing strip 208 can limit the other end of the capacitor core body 206, thereby achieving a limiting effect on both sides and preventing the capacitor core body 206 from falling off. The side of the second sealing strip 208 is provided with a folded edge 210. When installing it, it needs to be inserted from the bottom of the square frame 1. After it reaches the position of the horizontal plate 2, it can be fixed with bolts 209. It should be noted that the width of the first sealing strip 102 and the second sealing strip 208 is the same and not large, so it will not affect the normal spraying area on the capacitor core body 206. In actual use, the second sealing strip 208 can be selected for use depending on the applicable situation. If the second sealing strip 208 is not used, it will not affect the normal use of this tooling.

[0040] The top of the square frame 1 is provided with a hook 105 and a label slot 106. A cover plate 107 is attached to the top of the square frame 1. The cover plate 107 is provided with a through slot 108 corresponding to the hook 105. The hook 105 passes through the through slot 108 and extends outward.

[0041] In this invention, before the spraying operation, a label can be placed in the label slot 106. The label can record key information such as production batch number, core specifications and dimensions, dielectric, withstand voltage rating, and gold spraying process parameters. When quality problems such as uneven gold spraying layer thickness or insufficient adhesion occur later, the label can be used to quickly locate the problematic batch and process, enabling quality traceability and root cause analysis. After the spraying is completed, the staff can also directly use this information to quickly determine the area where the processed capacitor core body 206 needs to be placed. The cover plate 107 can cover this area to prevent the label from being affected or damaged during spraying. At the same time, the through groove 108 on the cover plate 107 can ensure the normal extension of the hook 105, thereby moving the entire square frame 1 through the hook 105 to achieve the spraying effect.

[0042] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
