Description

Technical Field

[0001] This utility model relates to an anti-shaking structure for anodized hangers, belonging to the field of hangers. Background Technology

[0002] In the anodizing process of chip manufacturing, the pretreated chip substrate needs to participate in the electrolytic reaction as the anode to form an oxide film with insulating, wear-resistant, and chemically stable properties, laying the foundation for the subsequent electrical performance and structural protection of the chip. In practice, the chip substrate is precisely placed in a specific electrolyte (in the chip industry, to avoid impurities affecting the purity of the oxide film, low-impurity, high-purity electrolytes such as oxalic acid and phosphoric acid are often chosen), paired with an inert metal (such as platinum, which, due to its stable chemical properties, avoids participating in the electrode reaction) as the cathode. By applying a stable DC voltage or pulsed voltage, the anodizing reaction is triggered. After energization, the chip anode surface oxidizes, gradually forming a uniform and dense oxide film. This film effectively isolates external environmental interference, improving the chip's lifespan and operational stability. To improve production efficiency and meet the needs of batch processing, the process often adopts a layout design of "multi-ring support + batch clamping": On a single ring, multiple sets of support structures composed of bottom bends and side bends are evenly installed. Each set of support structures supports the bottom of the chip through the bottom bend and clamps the side wall of the chip from the horizontal direction through the side bend, thus achieving the initial positioning of the chip. Then, multiple such rings are arranged and fixed in a vertically equidistant manner, so that each set of support structures can be used to place one chip. Finally, the entire ring assembly is placed in the electrolytic cell, which can complete the anodizing operation of multiple chips in one go, greatly shortening the processing time of a single batch and adapting to the efficiency requirements of chip mass production.

[0003] This support method relying on bottom and side bends has a significant limitation: the support structure can only constrain the chip from the bottom and sides, failing to effectively secure the top of the chip. When the annular assembly containing the chip is placed in the electrolytic cell, the electrolyte exerts multi-directional forces on the chip, and the chip itself experiences buoyancy within the electrolyte. Especially when the chip is small and lightweight, this buoyancy weakens the stability of the bottom bend in supporting the chip. Due to the lack of constraint at the top of the chip, it is highly susceptible to wobbling within the support structure under these external forces. If the wobbling exceeds the clamping range of the side bends, the chip will detach directly from the support space formed by the bottom and side bends. This not only leads to the failure of the chip's oxide film processing, requiring re-pretreatment and oxidation, increasing production costs and time, but the detached chip may also clog the pipes in the electrolytic cell or interfere with the oxidation reaction of other chips, causing batch processing quality problems and severely affecting the stability and production efficiency of the anodizing process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-shaking structure for anodizing racks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-shaking structure for anodizing fixtures, comprising:

[0006] The mating post has a downward recessed upper surface forming a first insertion hole. A insertion rod that mates with the first insertion hole is installed at the middle of the lower surface of the mating post. The insertion rod at the upper end of one mating post is inserted into the first insertion hole on another mating post.

[0007] A circular ring is arranged concentrically with the docking post. Three radial rods are installed at equal intervals on the outer surface of the circular ring. The end of the radial rod away from the circular ring is connected and fixed to the docking post. Multiple bottom bends for supporting the chip are installed at equal intervals on the outer surface of the circular ring. Two symmetrically arranged side bends are provided diagonally above the bottom bends. One end of the side bends is connected and fixed to the circular ring.

[0008] The flat ring is connected to the docking post via a connector. The upper surface of the flat ring has multiple guide holes that are equidistantly spaced in a ring shape to cooperate with the bottom bend. A guide rod is inserted into the guide hole. A pressure plate for holding the chip is installed at the lower end of the guide rod. A limiting member for limiting the relative position between the guide rod and the flat ring is provided on the upper side of the guide hole.

[0009] Furthermore, the connector includes a collar, and the lower end of the docking post is fitted with a collar. The outer surface of the collar is threaded with a positioning screw for limiting the relative position between the collar and the docking post. Multiple connecting plates are installed equidistantly on the annular side of the collar, and the end of the connecting plate away from the collar is connected and fixed to a flat ring.

[0010] Furthermore, the outer surface of the collar is provided with a threaded hole, the lower end of the mating post is provided with a blind hole that mates with the threaded hole, the positioning screw is threaded into the threaded hole, and one end of the positioning screw extends into the blind hole.

[0011] Furthermore, the limiting component includes a support sleeve, and a support sleeve arranged concentrically with the guide hole is provided on the upper side of the guide hole. The lower end of the support sleeve is connected and fixed to a flat ring. A rubber sleeve is glued inside the support sleeve, and the rubber sleeve wraps around the guide rod.

[0012] Furthermore, a base plate is provided on the lower side of the bottom docking post, a bottom post is installed in the middle of the upper surface of the base plate, a second insertion hole is opened on the upper surface of the base plate, the insertion rod at the lower end of the bottom docking post is inserted into the second insertion hole, and multiple fixing holes are opened in a ring at equal intervals on the edge of the upper surface of the base plate.

[0013] Furthermore, the cross-section of the plug rod is rectangular, and the cross-sections of the first plug hole and the second plug hole are both rectangular.

[0014] Furthermore, a rubber head is glued to the end of the connector rod away from the mating post, and the cross-sectional area of ​​the rubber head is equal to the cross-sectional area of ​​the connector rod.

[0015] Furthermore, the bottom bend has a "V" shaped structure, and the side bend has a "V" shaped structure.

[0016] The beneficial effects of this utility model are:

[0017] The flat ring and the docking post maintain their relative positions. The guide holes on the flat ring, spaced equidistantly, correspond one-to-one with the bottom bends on the circular ring. After the chip is placed in the support space formed by the bottom and side bends, the guide rod is adjusted downwards to press the pressure plate onto the upper part of the chip. This three-dimensional limiting structure, with bottom support, side clamping, and upper pressure, overcomes the shortcomings of traditional supports that only constrain the lower side. Even if the electrolyte flow in the electrolytic cell causes lateral impact, or the chip tends to float due to buoyancy, the pressure plate provides stable downward pressure, limiting the chip's vertical and radial movement. This eliminates the risk of chip detachment at the source, ensuring that all chips in a single batch can stably complete the anodizing operation. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] Please see Figures 1-5 This utility model provides a technical solution: an anti-shaking structure for anodizing fixtures, including a docking post 1, the upper surface of which is recessed downward to form a first insertion hole 11 with a rectangular cross-section, and an insertion rod 12 that mates with the first insertion hole 11 is installed at the middle of the lower surface of the docking post 1. The insertion rod 12 has a rectangular cross-section. The insertion rod 12 at the upper end of one docking post 1 is inserted into the first insertion hole 11 on another docking post 1. A base plate 4 is provided on the lower side of the bottom docking post 1, and a bottom post 41 is installed at the middle of the upper surface of the base plate 4. The upper surface of the bottom post 41 has a second insertion hole 43 with a rectangular cross-section. The insertion rod 12 at the lower end of the bottom docking post 1 is inserted into the second insertion hole 43. A plurality of fixing holes 42 are equidistantly spaced in a ring on the edge of the upper surface of the base plate 4. The insertion rod 12 engages with the first insertion hole 11 to restrict the relative rotation between the docking posts 1, ensuring that the support structure of the upper and lower rings 2 is always aligned. The first insertion hole 11 on the upper surface of the docking post 1 engages with the insertion rod 12, allowing multiple docking posts 1 to be spliced ​​together vertically according to processing requirements. The bottom docking post 1 is inserted into the second insertion hole 43 of the chassis 4 through the insertion rod 12. The chassis 4 is connected to the electrolytic cell or external bracket through the fixing hole 42, providing stable support for the entire fixture and preventing the fixture from shaking during electrolysis. A rubber head 13 is glued to the end of the insertion rod 12 away from the docking post 1. The cross-sectional area of ​​the rubber head 13 is equal to that of the cross-sectional area of ​​the insertion rod 12. The rubber head 13 increases the coefficient of friction between the insertion rod 12 and the inner wall of the first insertion hole 11 and the inner wall of the second insertion hole 43.

[0031] The circular ring 2 and the docking post 1 are arranged concentrically. Three radial rods 21 are installed in a ring at equal intervals on the outer surface of the circular ring 2. The end of the radial rod 21 away from the circular ring 2 is connected and fixed to the docking post 1. Multiple bottom bends 23 for supporting the chip are installed in a ring at equal intervals on the outer surface of the circular ring 2. The bottom bends 23 have a "V" shape. Two symmetrically arranged side bends 22 are provided diagonally above the bottom bends 23. The side bends 22 have a "V" shape. One end of the side bends 22 is connected and fixed to the circular ring 2. The chip is placed between the bottom bends 23 and the side bends 22. No complicated tools or professional skills are required. Ordinary operators can quickly complete the batch clamping.

[0032] See Figures 1-5 A collar 33 is fitted at the lower end of the docking post 1. A positioning screw 32 is threaded into the threaded hole 38 on the outer surface of the collar 33 to limit the relative position of the collar 33 and the docking post 1. A blind hole 14 is provided at the lower end of the docking post 1 to cooperate with the threaded hole 38, so that one end of the positioning screw 32 extends into the blind hole 14, thereby realizing the assembly of the collar 33 and the docking post 1.

[0033] Multiple connecting plates 31 are equidistantly mounted on the annular side of the collar 33. The end of the connecting plate 31 away from the collar 33 is connected and fixed to the flat ring 3. Multiple guide holes that mate with the bottom bend 23 are equidistantly opened on the upper surface of the flat ring 3. Guide rods 34 are inserted into the guide holes. A pressure plate 35 for holding the chip is installed at the lower end of the guide rod 34. A support sleeve 36 is arranged concentrically with the guide hole on the upper side of the guide hole. The lower end of the support sleeve 36 is connected and fixed to the flat ring 3. A rubber sleeve 37 is glued inside the support sleeve 36. Wrapped around the guide rod 34, the support sleeve 36 provides vertical guidance for the guide rod 34, preventing the guide rod 34 from tilting and causing the pressure plate 35 to shift. The rubber sleeve 37 tightly wraps around the guide rod 34, limiting the relative sliding between the guide rod 34 and the flat ring 3 through friction. During electrolysis, even if the fixture vibrates slightly, the guide rod 34 will not move up or down due to external force, ensuring that the pressure plate 35 maintains a stable pressure on the chip. This avoids both insufficient pressure leading to limit failure and excessive pressure damaging the chip substrate, thus meeting the requirements of chip processing.

[0034] The flat ring 3 forms a stable relative fixation with the docking post 1 through the positioning screw 32. Its annularly distributed guide holes correspond one-to-one with the bottom bends 23 on the circular ring 2. After the chip is placed in the support space formed by the bottom bends 23 and the side bends 22, the guide rods 34 in the guide holes can be adjusted downwards to drive the lower pressure plate 35 to move smoothly downwards until it presses against the upper surface of the chip. This ultimately forms a three-dimensional limiting structure with the bottom supported by the bottom bends 23, the sides clamped by the side bends 22, and the upper end pressed by the pressure plate 35. This structure makes up for the shortcomings of traditional support methods that can only constrain the lower side of the chip. Even if the flow of electrolyte in the electrolytic cell generates lateral impact force, or if the chip tends to float in the electrolyte due to buoyancy, the pressure plate 35 can continuously provide stable downward pressure, limiting the chip's displacement in the vertical direction and radial sway, fundamentally eliminating the risk of chip detachment, and ensuring that all chips in a single batch can maintain a stable posture during the anodizing process and successfully complete the uniform formation of the oxide film.
