Description

Technical Field

[0001] This utility model is a quick-assembly and disassembly anodizing fixture, belonging to the field of anodizing fixtures. Background Technology

[0002] In the semiconductor manufacturing field, the anodizing process on the chip surface is a key process to improve chip performance and reliability. In chip anodizing production, the mounting fixture, as the core carrier that directly supports the chip and realizes precise conduction between the chip and the electrolytic circuit, directly determines the uniformity of the chip oxide film, the chip yield, and the efficiency of the production process.

[0003] Currently, the traditional mounting fixtures used for chip anodizing are mostly modified from general-purpose metal fixtures, which are difficult to adapt to the special process requirements of chips. First, chips are extremely small and have a precise structure, but the fixed spacing of the brackets in traditional fixtures and the rough clamping structure make it impossible to flexibly adjust the clamping position and spacing according to the size of different chip models. This leads to chip misalignment and tilting after installation, resulting in uneven current distribution on the chip surface and excessive differences in oxide film thickness, which seriously affects the consistency of the chip's electrical performance. Second, chip anodizing production is mostly carried out in a multi-batch, small-volume mode, and different chip models need to be frequently switched for production. This places extremely high demands on the efficiency and versatility of the mounting fixtures. However, traditional fixtures mostly use bolts or clips to fix chips, and special tools such as tweezers and miniature wrenches are required for disassembly and assembly. This operation is cumbersome and time-consuming. When changing chip models in a single set of fixtures, dozens or even hundreds of clamping units often need to be adjusted one by one. This not only consumes a lot of production time, but also easily damages the chip due to operator hand tremors. Therefore, it is necessary to design an anodizing fixture that can be quickly disassembled and assembled. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anodizing fixture that can be quickly disassembled and assembled, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-detachable anodizing fixture, comprising:

[0006] The anti-drop tray includes a mesh screen and an anti-drop ring, with the anti-drop ring welded to the top edge of the mesh screen.

[0007] The suspension assembly includes a column, a base, and a hook. The base is bolted to the center of the top of the mesh, and the column is fixed to the top of the base. The hook is installed on the top of the column.

[0008] The hanging bracket assembly is provided in multiple sets, and each hanging bracket assembly is fixedly connected to the column.

[0009] Furthermore, the column is uniformly provided with through slots along the height direction, and there are two sets of through slots. The two sets of through slots are distributed perpendicularly to each other in the circumferential direction of the column, and the two sets of through slots are staggered in the height direction of the column, with the height difference between two adjacent through slots being consistent.

[0010] Furthermore, the top of the column is integrally connected with a threaded head, and the bottom of the hook is provided with a threaded sleeve that matches the threaded head.

[0011] Furthermore, the bracket assembly includes a mounting ring, a connecting structure, a plug rod, and a limiting structure. The mounting ring has multiple through holes arranged in a ring array. The connecting structure includes a connecting seat, a plug sleeve, and a fixing rod. The connecting seat is a rectangular frame design that matches the shape of the column. Plug sleeves are integrally formed on all four side walls of the connecting seat. The fixing rod is first inserted into the plug sleeves on both sides of the connecting seat using a clearance fit, and then a rigid connection between the fixing rod and the plug sleeve is achieved by welding. The plug rod passes through the through groove of the column and the plug sleeves at both ends of the connecting seat, and the upper surface of the plug rod is flush with the upper surface of the fixing rod. The mounting ring is located at the top of the plug rod and the fixing rod, and multiple limiting structures are evenly spaced on the outer periphery of the mounting ring.

[0012] Furthermore, a rectangular groove with a shape matching the column is provided at the center of the interior of the connector, and a second insertion hole is provided at both ends of the insertion rod. The two second insertion holes are aligned with any two opposite through holes on the mounting ring. The ends of the two fixing rods away from the connector are provided with a first insertion hole aligned with the through holes on the mounting ring.

[0013] Furthermore, fastening bolts are installed on the top of the plug sleeves at both ends of the connector, and corresponding screw holes are opened on the plug rods below the two fastening bolts. The shape of the plug rods matches the internal shape of the plug sleeves and the through grooves. The top of the plug rods on both sides of the connector are symmetrically provided with positioning grooves, and the two positioning grooves are flush with the outer edges of the two plug sleeves respectively.

[0014] Furthermore, the limiting structure includes a fixed plate, hinge seats, return springs, a central disc, limiting hooks, and connecting sleeves. The fixed plate has four hinge seats arranged in a circular array at the end away from the center of the mounting ring, and connecting sleeves are hinged inside the hinge seats. The end of the connecting sleeve away from the fixed plate is threaded with a limiting hook, and the hook portion of the limiting hook points towards the center of the fixed plate. The four connecting sleeves are hooked to the side of the fixed plate near the center, and the other end of the returning spring is hooked to the outer wall of the central disc.

[0015] Furthermore, the cross-section of the fixing plate is designed as an inverted "L". The vertical plate portion of the fixing plate fits against the outer peripheral wall of the mounting ring, and the horizontal plate portion of the fixing plate is placed on top of the mounting ring. A third insertion hole is provided on the horizontal plate, and the diameter of the third insertion hole is consistent with the diameter of the through hole on the mounting ring. During assembly, the bolt passes through the third insertion hole and the through hole to connect with the nut. When the through hole is aligned with the first insertion hole, the bolt passes through the third insertion hole, the through hole, and the first insertion hole in sequence to connect with the nut. When the through hole is aligned with the second insertion hole, the bolt passes through the third insertion hole, the through hole, and the second insertion hole in sequence to connect with the nut.

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

[0017] 1. This application achieves precise fitting and stable fixation of chips by setting up multiple sets of flexibly adjustable bracket components and precision clamping structures. On the one hand, the bracket components and the columns are detachably connected through structures such as through slots and inserts. The through slots on the columns are evenly distributed along the height direction and perpendicularly intersecting in the circumferential direction. The installation height and spacing of the bracket components can be flexibly adjusted according to the size of different chip models to ensure the smooth progress of chip anodizing production. On the other hand, the limiting structure in the bracket components includes four limiting hooks with reset springs, which can form a flexible and stable clamping of the chip, avoiding chip tilting or structural damage due to improper clamping force. This effectively ensures uniform current distribution on the chip surface and significantly improves the consistency of chip electrical performance and production yield.

[0018] 2. The bracket assembly can be initially fixed by inserting a rod through the through slot of the column and the plug-in sleeve of the connector. With the quick locking of the fastening bolts and screw holes, the bracket assembly can be installed and disassembled without complicated tools. The connector is not directly fixed to the column by bolts, but by inserting a rod through both the through slot of the column and the plug-in sleeve of the connector, and then connecting it to the plug-in sleeve by fastening bolts. This prevents the bracket assembly from sliding down due to loose bolts.

[0019] 3. The hook and column are connected by threaded head and threaded sleeve. The disassembly and assembly process can be completed by manual rotation. After the installation ring, insertion rod and fixing rod are aligned with the insertion hole through the through hole, the bolt can be inserted to fix them. When changing the chip model of a single set of hangers, there is no need to adjust dozens of clamping units one by one, which greatly shortens the disassembly and assembly time. This convenient disassembly and assembly design not only reduces the technical level requirements of the operators, but also reduces the risk of chip damage caused by operation vibration, significantly improves production efficiency, and perfectly adapts to the multi-batch, small-volume production mode of chips.

[0036] 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.

[0037] Please see Figures 1 to 7 This utility model provides a technical solution: a quick-assembly and detachable anodizing hanger, including an anti-drop tray 1, which includes a mesh 101 and an anti-drop ring 102, with the anti-drop ring 102 welded to the top edge of the mesh 101. A suspension assembly 2 includes a column 201, a base 202, and a hook 203. The base 202 is bolted to the center of the top of the mesh 101, and the column 201 is fixed to the top of the base 202. The hook 203 is installed on the top of the column 201. Multiple hanger assemblies 3 are provided, and each hanger assembly 3 is fixedly connected to the column 201. The mesh 101 of the anti-drop tray 1... 1. It ensures smooth electrolyte flow, guaranteeing full contact between the chip to be processed and the electrolyte, meeting the requirements of the anodizing reaction. At the same time, the anti-drop ring 102 effectively prevents the chip from accidentally falling off, avoiding oxidation failure or equipment blockage due to chip detachment, thus reducing production losses. The base 202 of the suspension assembly 2 is connected to the mesh 101 by bolts, which facilitates the subsequent disassembly and maintenance of the column 201, hook 203 or anti-drop tray 1, without the need for complete scrapping like traditional integrated hangers, reducing resource waste. Multiple hanger assemblies 3 can carry more chips according to production needs, increasing the single anodizing processing capacity and improving production efficiency.

[0038] Please see Figure 4 The column 201 has through slots 2011 evenly distributed along its height direction, and there are two sets of through slots 2011. The two sets of through slots 2011 are perpendicular to each other in the circumferential direction of the column 201, and are staggered in the height direction of the column 201. The height difference between two adjacent through slots 2011 is the same. The two sets of through slots 2011 distributed perpendicularly in the circumferential direction on the column 201 allow the hanger assembly 3 to be installed around the column 201, making full use of space, increasing the number of chips that the hanger can support, and further improving production efficiency. Secondly, the staggered through slots 2011 in the height direction and the consistent height difference between adjacent slots allow the hanger assembly 3 to be precisely adjusted according to the chip size, adapting to chips of different specifications, and avoiding the problem of poor chip compatibility caused by the fixed spacing of traditional hangers.

[0039] Please see Figure 4The top of the column 201 is integrally connected with a threaded head 205, and the bottom of the hook 203 is provided with a threaded sleeve 204 that matches the threaded head 205. The threaded head 205 and the threaded sleeve 204 are compatible, forming a convenient threaded connection design. No special tools are required for disassembly and assembly. Installation and disassembly can be completed by simply rotating the hook 203 manually, which greatly improves the ease of operation and solves the problem that the traditional welded hook 203 cannot be disassembled and needs to be replaced as a whole after damage.

[0040] Please see Figure 2 and Figure 5 The bracket assembly 3 includes a mounting ring 4, a connecting structure 5, a plug rod 6, and a limiting structure 7. The mounting ring 4 has multiple through holes 401 arranged in a ring array. The connecting structure 5 includes a connecting seat 501, a plug sleeve 502, and a fixing rod 503. The connecting seat 501 is a rectangular frame design that matches the shape of the column 201. Plug sleeves 502 are integrally formed on all four side walls of the connecting seat 501. The fixing rod 503 is first inserted into the plug sleeves 502 on both sides of the connecting seat 501 using a clearance fit, and then a rigid connection between the fixing rod 503 and the plug sleeves 502 is achieved by welding. The plug rod 6 passes through the through groove 2011 of the column 201 and the plug sleeves 502 at both ends of the connecting seat 501. The plug rod 6 is flush with the upper surface of the fixing rod 503. The mounting ring 4 is set with… Multiple limiting structures 7 are evenly spaced at the top of the insertion rod 6 and the fixing rod 503, and on the outer periphery of the mounting ring 4. The rectangular frame design of the connecting seat 501 matches the shape of the column 201, ensuring that the connecting seat 501 and the column 201 fit tightly, improving the installation stability of the bracket assembly 3 and preventing the chip from tilting. The fixing rod 503 and the insertion sleeve 502 are first fitted with a gap and then welded, which not only ensures the accurate installation of the fixing rod 503, but also achieves a rigid connection through welding, ensuring that the fixing rod 503 does not shake or deform when carrying the chip. The insertion rod 6 passes through the through slot 2011 of the column 201 and the insertion sleeve 502 of the connecting seat 501, which can achieve the initial fixation of the bracket assembly 3. With the fastening bolt 504 and the screw hole 602 locked together, disassembly and assembly can be completed without complicated tools, simplifying the operation process.

[0041] Please see Figure 5 The connector 501 has a rectangular groove 5011 with a shape matching the column 201 at its center. Both ends of the insert rod 6 are provided with second insertion holes 601. The two second insertion holes 601 are aligned with any two opposite through holes 401 on the mounting ring 4. The ends of the two fixing rods 503 away from the connector 501 are provided with first insertion holes 5031 aligned with the through holes 401 on the mounting ring 4. The second insertion holes 601 of the insert rod 6 and the first insertion holes 5031 of the fixing rod 503 are aligned with the through holes 401 of the mounting ring 4, so that the bolt can quickly pass through the holes to fix the mounting ring 4 without repeatedly adjusting the position of the mounting ring 4, improving installation efficiency. At the same time, it ensures that the mounting ring 4 is firm and does not shift, preventing the chip from shifting due to the shaking of the mounting ring 4.

[0042] Please see Figure 5 and Figure 7 The connector 501 has fastening bolts 504 installed on the top of the plug sleeves 502 at both ends, and corresponding screw holes 602 are opened on the plug rods 6 below the two fastening bolts 504. The shape of the plug rods 6 matches the internal shape of the plug sleeves 502 and the through groove 2011. The top of the plug rods 6 on both sides of the connector 501 is symmetrically provided with positioning grooves 603. The two positioning grooves 603 are flush with the outer edges of the two plug sleeves 502 respectively. The top fastening bolt 504 is compatible with the screw hole 602 of the plug rod 6, which can firmly fix the plug rod 6 in the plug sleeve 502, preventing the plug rod 6 from sliding due to electrolyte impact or chip weight. Secondly, the shape of the plug rod 6 matches the plug sleeve 502 and the through groove 2011, reducing gaps, improving installation accuracy, and avoiding electrolyte accumulation and corrosion. Furthermore, the connector 501 is fixed by the plug rod 6 passing through the through groove 2011 and the plug sleeve 502, forming a linkage structure of "plug rod 6 - column 201 - connector 501". With the secondary locking of the fastening bolt 504, even if the bolt is loose, the plug rod 6 can still be locked, preventing the bracket assembly 3 from sliding down and ensuring the stability of the chip position. Finally, the positioning groove 603 at the top of the plug rod 6 is flush with the outer edge of the plug sleeve 502, providing a positioning reference for the mounting ring 4, improving the installation efficiency of the mounting ring 4, and preventing the mounting ring 4 from sliding horizontally.

[0043] Please see Figure 6 The limiting structure 7 includes a fixed plate 701, hinge seats 702, return springs 703, a center plate 704, limiting hooks 705, and connecting sleeves 706. Four hinge seats 702 are arranged in a circular array at the end of the fixed plate 701 furthest from the center of the mounting ring 4. Connecting sleeves 706 are hinged within each hinge seat 702. A limiting hook 705 is threaded to the end of each connecting sleeve 706 furthest from the fixed plate 701, and the hook portion of the limiting hook 705 points towards the center of the fixed plate 701. A return spring 703 is hooked onto the side of each of the four connecting sleeves 706 closest to the center of the fixed plate 701, and the other end of each return spring 703 is aligned with the center. The outer wall of the disk 704 is hooked and connected. The limiting hook 705 is threadedly connected to the connecting sleeve 706. The extension length of the limiting hook 705 can be adjusted according to the chip size to adapt to chips of different thicknesses and packaging forms, improving versatility. The connecting sleeve 706 is hinged to the hinge seat 702. With the help of the reset spring 703, the connecting sleeve 706 is connected to the central disk 704. It can automatically adjust the opening angle of the limiting hook 705 according to the chip size to form a flexible clamping of the chip and avoid damage to the chip due to excessive clamping force. The four limiting hooks 705 are distributed in a ring array to fix the chip evenly from all sides, ensuring that the chip is subjected to balanced force, preventing the chip from tilting, and ensuring uniform oxide film thickness.

[0044] Please see Figure 2 and Figure 6The fixing plate 701 has an inverted "L" shaped cross-section. The vertical portion of the fixing plate 701 fits snugly against the outer peripheral wall of the mounting ring 4, while the horizontal portion is positioned at the top of the mounting ring 4. A third insertion hole 7011 is provided on the horizontal plate, and the diameter of the third insertion hole 7011 matches the diameter of the through hole 401 on the mounting ring 4. During assembly, bolts pass through the third insertion hole 7011 and the through hole 401 to connect with the nut. When the through hole 401 aligns with the first insertion hole 5031, the bolts sequentially pass through the third insertion hole 7011, the through hole 401, and the first insertion hole 5031 to connect with the nut. When the through hole 401 aligns with the second insertion hole 601, the bolts sequentially pass through the third insertion hole 7011, the through hole 401, and the second insertion hole 601 to connect with the nut. The fixing plate 701 has an inverted "L" shaped cross-section. The design features a vertical plate that fits snugly against the outer periphery of the mounting ring 4, while a horizontal plate is positioned on top of the mounting ring 4. This design ensures a tight connection between the fixing plate 701 and the mounting ring 4, while preventing the mounting ring 4 from tilting upwards. The third insertion hole 7011 of the horizontal plate has the same diameter as the through hole 401 of the mounting ring 4. Bolts can be inserted through the third insertion hole 7011, the through hole 401, and connected to the first insertion hole 5031 or the second insertion hole 601 as needed, adapting to different connection scenarios. This ensures that the limiting structure 7 forms a stable whole with the mounting ring 4, the insertion rod 6, or the fixing rod 503, preventing the limiting structure 7 from loosening. At the same time, the bolt connection facilitates disassembly, allowing for separate maintenance and replacement of the limiting structure 7, thus reducing maintenance costs.
