Description

Technical Field

[0001] This utility model relates to the field of semiconductor sorting equipment technology, and in particular to a positioning box and positioning device. Background Technology

[0002] In semiconductor sorting processes, square iron rings and their matching cassettes are key tooling for carrying and transporting wafer dies. The iron ring assembly typically consists of a metal frame, a blue (or white) film, and the diced wafer dies adhered to it. The blue film provides a flat support surface, ensuring stable operation of the ejector pins and nozzles during sorting. Currently, cassettes commonly use a four-block structure for positioning: the four blocks constrain the cassette's movement in the X and Y directions, while positioning in the Z direction relies on the cassette's own weight. Although this structure achieves basic installation functionality, it reveals several problems in practical applications. When the robotic arm picks up the iron ring from the cassette, the ring's position often shifts, leading to inaccurate posture on the robotic arm and resulting in positional deviations when placed on the work platform, affecting the positioning efficiency of subsequent processes. If the deviation is too large, it can even cause a hard impact between the iron ring and the equipment platform. Similarly, during the process of returning the iron ring to the cassette, the relative misalignment between the cassette and the iron ring can easily cause collisions, leading to iron ring deformation or wafer die detachment. Furthermore, during equipment operation, the iron rings inside the material box vibrate due to machine vibration, causing them to shake and produce noticeable noise. In severe cases, this can cause some core particles to detach from the blue film. During transportation, the iron rings repeatedly move, vibrate, and impact within the gaps, further exacerbating the risk of core particle detachment. To compensate for positioning uncertainties, existing systems often require additional scanning positioning sensors for real-time correction, which not only increases equipment costs but also raises control complexity.

[0024] In one embodiment, both the first positioning component and the second positioning component are connected to the material box, and both the first positioning component and the second positioning component are capable of abutting against the positioning base.

[0026] In one embodiment, the number of the first positioning components is at least one, and the number of the second positioning components is at least one;

[0027] And / or,

[0028] The number of iron rings is multiple, the number of limiting grooves is the same as the number of iron rings and is set one-to-one, the number of third positioning components is the same as the number of iron rings and is set one-to-one, and the number of fourth positioning components is the same as the number of iron rings and is set one-to-one.

[0029] In this embodiment of the invention, to facilitate manual or automated replacement of the material box, an assembly gap exists between the material box and the limiting groove on the positioning base. This allows the material box to slide against the groove wall and reciprocate between a second initial position and a second fixed position. Consequently, the actual position of the material box randomly shifts each time it is placed, making highly repeatable and precise positioning impossible. Simultaneously, the iron ring itself needs to be freely removed from or placed into the material box. Therefore, a large gap is also maintained between the iron ring and the receiving groove on the material box, allowing the iron ring to reciprocate between the first initial position and the first fixed position relative to the receiving groove, preventing the formation of a stable relative position. This positioning material box and positioning device, by setting a first positioning mechanism and a second positioning component, solves the problems of inaccurate positioning of the material box and iron ring due to the assembly gap in existing structures, easy collisions during robotic arm handling, and noise and wafer chip shedding caused by iron ring swaying during equipment operation or transportation. The first positioning mechanism includes a first positioning component and a second positioning component, which can push the material box from a second initial position to a second fixed position in a first direction and a second direction, respectively, so that the material box fits against the corresponding groove wall of the limiting groove, thereby eliminating the relative gap between the material box and the positioning base, achieving high repeatability positioning, and avoiding posture deviation and collisions of the robot arm when picking up or placing iron rings due to the positional displacement of the material box. The second positioning mechanism includes a third positioning component and a fourth positioning component, which are connected to the material box, and can push the iron ring from the first initial position to the first fixed position in the second direction and the first direction, respectively, so that it fits against the corresponding groove wall of the receiving groove, thereby restricting the degree of freedom of the iron ring in the material box and achieving its stable positioning in the material box. Through this two-stage positioning structure, the spatial positional consistency between the material box and the iron ring is significantly improved, which not only improves the accuracy and reliability of the robot arm's operation, but also effectively suppresses the relative movement of the iron ring under equipment vibration or transportation impact, and reduces the noise caused by impact and the risk of the core particle falling off the blue film. Meanwhile, due to the improved positioning accuracy, the robotic arm can quickly complete alignment, reducing adjustment time and improving work efficiency. It also simplifies reliance on additional scanning positioning sensors, thereby reducing system control complexity and cost. The overall structure achieves automatic centering and stable fixation through the active pushing action of the positioning components, improving the positioning accuracy and operational stability of the tooling system. This embodiment of the invention eliminates the assembly gap between the material box and the positioning base by using a first positioning mechanism to move the material box from a second initial position to a second fixed position, achieving high repeatability positioning of the material box. By using a second positioning mechanism to move the iron ring from a first initial position to a first fixed position, the freedom of the iron ring within the material box is restricted, ensuring its stable position.This structure effectively solves the problems of robot arm picking and placing deviations and collision risks caused by inaccurate positioning of the material box and iron ring in the existing structure, thus improving the reliability of picking and placing operations. At the same time, it reduces the relative movement and impact of the iron ring during equipment operation or transportation, reducing noise generation and the risk of wafer cores falling off the blue film. Due to the improved positioning accuracy, the robot arm can quickly align, which helps to improve work efficiency and reduces the dependence on additional positioning sensors, thereby simplifying the control process and reducing system costs.

[0053] In semiconductor sorting processes, square iron rings and their matching cassettes are key tooling for carrying and transporting wafer dies. The iron ring assembly typically consists of a metal frame, a blue (or white) film, and the diced wafer dies adhered to it. The blue film provides a flat support surface, ensuring stable operation of the ejector pins and nozzles during sorting. Currently, cassettes commonly use a four-block structure for positioning: the four blocks constrain the cassette's movement in the X and Y directions, while positioning in the Z direction relies on the cassette's own weight. Although this structure achieves basic installation functionality, it reveals several problems in practical applications. When the robotic arm picks up the iron ring from the cassette, the ring's position often shifts, leading to inaccurate posture on the robotic arm and resulting in positional deviations when placed on the work platform, affecting the positioning efficiency of subsequent processes. If the deviation is too large, it can even cause a hard impact between the iron ring and the equipment platform. Similarly, during the process of returning the iron ring to the cassette, the relative misalignment between the cassette and the iron ring can easily cause collisions, leading to iron ring deformation or wafer die detachment. Furthermore, during equipment operation, the iron rings inside the material box vibrate due to machine vibration, causing them to shake and produce noticeable noise. In severe cases, this can cause some core particles to detach from the blue film. During transportation, the iron rings repeatedly move, vibrate, and impact within the gaps, further exacerbating the risk of core particle detachment. To compensate for positioning uncertainties, existing systems often require additional scanning positioning sensors for real-time correction, which not only increases equipment costs but also raises control complexity.

[0054] After careful investigation, the applicant discovered that the root cause of the aforementioned problems lies in the fact that the existing structure is designed to meet both the dual requirements of operability and precise positioning. Specifically, to facilitate manual or automated replacement of the material box, a certain assembly gap must be reserved between the material box and the four limiting blocks. This gap directly leads to random offsets in the actual position of the material box each time it is placed, making it impossible to achieve highly repeatable and precise positioning. At the same time, the iron ring itself also needs to be freely removed and placed in the material box. Therefore, a large gap is also maintained between the iron ring and the material box, causing it to float within the box and unable to form a stable relative position. It is precisely because of the inconsistent positioning of the material box itself, coupled with the uncertainty of the position of the iron ring within the material box, that the robotic arm cannot accurately align itself when performing pick-and-place operations, making collision accidents highly likely. Furthermore, during equipment operation or transportation, the iron ring swings freely in the gap, continuously impacting the side wall of the material box under vibration and shock. This not only generates noise but also damages the adhesion of the blue film to the wafer chip through mechanical vibration, ultimately causing the chip to detach and severely affecting product yield.

[0055] The main purpose of this utility model is to propose a positioning box and positioning device to solve the problem of inaccurate positioning of the box and the iron ring.

[0056] Please see Figures 1 to 3In one embodiment of this utility model, the positioning box and positioning device 100 includes a box 1, a positioning base 2, a first positioning mechanism 3, and a second positioning mechanism 4. The box 1 has a receiving groove 121 for accommodating an iron ring 200. The iron ring 200 slides against the groove wall of the receiving groove 121. The iron ring 200 has a first initial position and a first fixed position, and can reciprocate between the first initial position and the first fixed position. The positioning base 2 has a limiting groove 21 for accommodating the box 1. The box 1 slides against the groove wall of the limiting groove 21. The box 1 has a second initial position and a second fixed position, and can reciprocate between the second initial position and the second fixed position. The first positioning mechanism 3 includes a first positioning component 31 and a second positioning component 32. The first positioning component 31 can push the box 1 along a first direction from the second initial position to the second fixed position, and the second positioning component 32 can push the box 1 along a second direction from the second initial position to the second fixed position. The box 1 is located at the second fixed position, and the box 1 moves along the first direction... The two sides of the material box 1, which are arranged opposite to each other, can respectively abut against the first positioning component 31 and the limiting groove 21 along one side of the groove wall along the first direction. The two sides of the material box 1, which are arranged opposite to each other along the second direction, can respectively abut against the second positioning component 32 and the limiting groove 21 along one side of the groove wall along the second direction. The second positioning mechanism 4 includes a third positioning component 41 and a fourth positioning component 42. The third positioning component 41 can push the iron ring 200 to move from the first initial position to the first fixed position along the second direction. The fourth positioning component 42 can push the iron ring 200 to move from the first initial position to the first fixed position along the first direction. The iron ring 200 is located in the first fixed position. The two sides of the iron ring 200, which are arranged opposite to each other along the first direction, can respectively abut against the fourth positioning component 42 and the receiving groove 121 along one side of the groove wall along the first direction. The two sides of the iron ring 200, which are arranged opposite to each other along the second direction, can respectively abut against the third positioning component 41 and the receiving groove 121 along one side of the groove wall along the second direction. The first direction and the second direction are perpendicular to each other.

[0057] In the embodiments of this utility model, such as Figure 3As shown, the first direction is the front-to-back direction, and the second direction is the left-to-right direction. To facilitate manual or automated replacement of the material box 1, an assembly gap exists between the material box 1 and the limiting groove 21 on the positioning base 2. This allows the material box 1 to slide against the wall of the limiting groove 21, reciprocating between the second initial position and the second fixed position. This results in a random offset in the actual position of the material box 1 each time it is placed, making highly repeatable and precise positioning impossible. Simultaneously, the iron ring 200 itself needs to be freely removed from or placed into the material box 1. Therefore, a large gap is also maintained between the iron ring 200 and the receiving groove 121 on the material box 1, allowing the iron ring 200 to reciprocate between the first initial position and the first fixed position relative to the receiving groove 121, making it impossible to form a stable relative position. This positioning material box and positioning device 100, by setting a first positioning mechanism 3 and a second positioning component 32, solves the problems of inaccurate positioning of the material box 1 and the iron ring 200 due to the assembly gap in the existing structure, easy collisions during robotic handling, and noise and wafer chip shedding caused by the shaking of the iron ring 200 during equipment operation or transportation. The first positioning mechanism 3 includes a first positioning component 31 and a second positioning component 32, which can push the material box 1 from the second initial position to the second fixed position in the first direction and the second direction respectively, so that the material box 1 fits against the corresponding groove wall of the limiting groove 21, thereby eliminating the relative gap between the material box 1 and the positioning base 2, achieving high repeatability positioning, and avoiding posture deviation and collision of the robot arm when picking up or placing the iron ring 200 due to the positional deviation of the material box 1; the second positioning mechanism 4 includes a third positioning component 41 and a fourth positioning component 42, which are connected to the material box 1, and can push the iron ring 200 from the first initial position to the first fixed position in the second direction and the first direction respectively, so that it fits against the corresponding groove wall of the receiving groove 121, thereby restricting the degree of freedom of the iron ring 200 in the material box 1 and achieving its stable positioning in the material box 1. This two-stage positioning structure significantly improves the spatial consistency between the material box 1 and the iron ring 200. This not only enhances the accuracy and reliability of the robotic arm's operations but also effectively suppresses the relative movement of the iron ring 200 under equipment vibration or transportation impacts, reducing noise caused by impacts and the risk of the core particle detaching from the blue film. Simultaneously, due to the improved positioning accuracy, the robotic arm can quickly complete alignment, reducing adjustment time and improving operational efficiency. It also simplifies reliance on additional scanning positioning sensors, thereby reducing system control complexity and cost. The overall structure achieves automatic centering and stable fixation through the active pushing action of the positioning components, improving the positioning accuracy and operational stability of the tooling system.

[0058] The technical solution of this utility model eliminates the assembly gap between the material box 1 and the positioning base 2 by using a first positioning mechanism 3 to move the material box 1 from the second initial position to the second fixed position, thus achieving high repeatability positioning of the material box 1. By using a second positioning mechanism 4 to move the iron ring 200 from the first initial position to the first fixed position, the degree of freedom of the iron ring 200 within the material box 1 is restricted, stabilizing its position. This structure effectively solves the problems of robot arm picking and placing deviation and collision risk caused by inaccurate positioning of the material box 1 and the iron ring 200 in existing structures, improving the reliability of picking and placing operations. At the same time, it reduces the relative movement and impact of the iron ring 200 during equipment operation or transportation, reducing noise generation and the risk of wafer cores falling off the blue film. Due to the improved positioning accuracy, the robot arm can quickly align, which helps to improve work efficiency and reduces the dependence on additional positioning sensors, thereby simplifying the control process and reducing system costs.

[0059] Please see Figures 3 to 5In one embodiment, the first positioning component 31 includes a first spring 311, and the two ends of the limiting groove 21, which are arranged opposite each other along the first direction, are a first end 211 and a second end 212, respectively. The first end 211 and the side of the material box 1 facing the first end 211 can both abut against the first spring 311, and the first spring 311 can push the material box 1 to move from the second initial position to the second fixed position along the first direction; the second positioning component 32 includes a second spring 321, and the two ends of the limiting groove 21, which are arranged opposite each other along the second direction, are a third end 213 and a fourth end 214, respectively. The third end 213 and the side of the material box 1 facing the first end 211 can both abut against the first spring 311, and the first spring 311 can push the material box 1 to move from the second initial position to the second fixed position along the first direction; the second positioning component 32 includes a second spring 321, and the two ends of the limiting groove 21, which are arranged opposite each other along the second direction, are a third end 213 and a fourth end 214, respectively. The side of box 1 facing the third end 213 can abut against the second spring 321. The second spring 321 can push box 1 to move from the second initial position to the second fixed position along the second direction. When box 1 is in the second fixed position, the two sides of box 1 that are arranged opposite to each other along the first direction can abut against the first spring 311 and the second end 212 respectively. The two sides of box 1 that are arranged opposite to each other along the second direction can abut against the second spring 321 and the fourth end 214 respectively. Specifically, in this structure, the first spring 311 forms a stable force transmission path through the double abutment with the first end 211 and box 1. When the material box 1 is inserted into the limiting groove 21, if its second initial position is biased towards the first end 211, the first spring piece 311 will undergo elastic deformation and store energy under the compression action. As it is inserted into place, the first spring piece 311 generates a restoring force based on its own deformation recovery ability, continuously pushing the material box 1 towards the second end 212 until the material box 1 is completely attached to the groove wall of the second end 212, achieving single-sided reference tightness, thereby effectively eliminating the assembly gap in the first direction and ensuring the height consistency of the material box 1 in each installation position. The second positioning component 32 can adopt the same structure as the first positioning component 31, and achieve similar positioning in the second direction through the second spring piece 321: the two ends of the second spring piece 321 abut against the third end 213 and the material box 1 respectively. After being compressed during the insertion of the material box 1, it releases the restoring force, pushing the material box 1 to move towards the fourth end 214 and fit, thereby constraining its degree of freedom in the second direction. This bidirectional positioning structure enables the material box 1 to move from the second initial position to the second fixed position, which not only improves the planar positioning accuracy of the material box 1 on the positioning base 2, but also avoids problems such as collisions and posture deviations when the robot arm picks up or places the iron ring 200 due to position offset. At the same time, the spring structure is simple, requires no external drive, and responds quickly, with the advantages of low cost, high reliability, and easy maintenance. The overall design is compact and suitable for tooling environments with high requirements for space and stability in semiconductor sorting equipment, which significantly improves the positioning repeatability and operational safety of the material box 1 system.

[0060] Please see Figure 10 , Figure 11 and Figure 12In one embodiment, the first positioning component 31 includes a first elastic reset member 312 and a first abutment member 313, the first elastic reset member 312 being connected to the first abutment member 313. The two ends of the limiting groove 21, which are arranged opposite each other along the first direction, are a first end 211 and a second end 212, respectively. The first elastic reset member 312 and the first abutment member 313 can respectively abut against the first end 211 and the side of the material box 1 facing the first end 211. The first elastic reset member 312 can push the material box 1 to move from the first initial position to the first fixed position along the first direction. The second positioning component 32 includes a second elastic reset member 322 and a second abutment member 323, the second elastic reset member 322 being connected to the second abutment member 323. The two ends of the limiting groove 21, which are arranged opposite each other along the second direction, are a third end 213 and a fourth end 214, respectively. The second elastic reset member 322 and the second abutment member 323 can respectively abut against the third end 213 and the side of the material box 1 facing the third end 213. The second elastic reset member 322 can push the material box 1 to move from the first initial position to the first fixed position along the second direction. The material box 1 is located in the first fixed position. The side of the material box 1 along the first direction can abut against the second end 212. The other side of the material box 1 along the first direction can abut against the first elastic reset member 312 or the first abutment member 313. The side of the material box 1 along the second direction can abut against the fourth end 214. The other side of the material box 1 along the second direction can abut against the second elastic reset member 322 or the second abutment member 323. Specifically, by setting the first positioning component 31 and the second positioning component 32, the installation accuracy and repeatability of the material box 1 on the positioning base 2 are effectively improved. The first positioning component 31 includes a first elastic reset member 312 and a first abutment member 313. After being connected, the two abut against the first end 211 of the limiting groove 21 and the side of the material box 1 facing the first end 211, respectively, forming a stable force transmission path. The restoring force of the first elastic reset member 312 pushes the material box 1 relative to the positioning base 2 towards the second end 212, so that it fits against the second end 212, achieving single-sided reference tightness in the first direction, thereby eliminating assembly gaps and avoiding collisions or posture deviations of the robot arm when picking up or placing the iron ring 200 due to the positional displacement of the material box 1. Similarly, the second positioning component 32 includes a second elastic reset member 322 and a second abutment member 323. After being connected, the two abut against the third end 213 and the side of the material box 1 facing the third end 213, respectively. Through the same mechanism, the material box 1 is pushed to move towards the fourth end 214 and fit against it, achieving precise positioning in the second direction. This bidirectional positioning structure allows the material box 1 to move from the second initial position to the second fixed position, jointly constraining the degree of freedom of the material box 1 in the plane and significantly improving its spatial positioning consistency. Due to the use of elastic pushing method, the structure does not require external drive, responds quickly, and has a certain buffering capacity, which can effectively suppress the shaking and impact of the material box 1 caused by vibration during equipment operation or transportation, reducing noise and the risk of wafer core detachment.The overall solution is simple in structure, highly reliable, and easy to maintain, making it suitable for the high-precision and high-stability tooling positioning requirements in semiconductor sorting equipment.

[0061] Please see Figure 11 In this embodiment, the first positioning component 31 and the second positioning component 32 can adopt the ball-head plunger structure in the prior art. The ball-head plunger has a spring inside, serving as an elastic reset element. When the material box 1 is pressed down for insertion, the ball head compresses the spring, generating a continuous thrust that pushes the material box 1 towards the second end 212 or the fourth end 214 until it reaches the second fixed position, achieving automatic positioning. Simultaneously, the ball head can roll or swing slightly within the plunger, allowing the material box 1 to be smoothly inserted even with a slight angle deviation during descent, avoiding jamming or stuck phenomena and ensuring a smooth and unobstructed insertion process. Furthermore, the ball-head plunger can be threaded onto the positioning base 2, and its extension length can be adjusted by rotation to precisely control the preload and initial contact position. After adjustment, the threaded portion is tightened and fixed by the set screw 5 to prevent loosening or displacement due to vibration during equipment operation. This adjustment and locking mechanism not only ensures the adjustability and stability of the positioning accuracy but also improves the maintainability and versatility of the tooling system.

[0062] According to one embodiment of the present invention, both the first fixing component and the second fixing fastener can be telescopic rods. The material box 1 is moved from the second initial position to the second fixed position by the two telescopic rods along the first direction and the second direction, respectively. After the material box 1 reaches the second fixed position, the two telescopic rods, the side wall of the limiting groove 21 along the first direction and the side wall of the limiting groove 21 along the second direction can respectively abut against the four sides of the material box 1, thereby restricting the movement of the material box 1 and ensuring the adjustability and stability of the positioning accuracy.

[0063] Please see Figures 6 to 9In one embodiment, the third positioning component 41 includes a first pressure plate 411 and a third spring piece 412, the third spring piece 412 being connected to the first pressure plate 411. The fourth positioning component 42 includes a second pressure plate 421 and a fourth spring piece 422, the fourth spring piece 422 being connected to the second pressure plate 421. Both the first pressure plate 411 and the second pressure plate 421 are connected to the material box 1. The material box 1 is also provided with a first clearance hole 122 and a second clearance hole 123 communicating with the receiving groove 121. The two ends of the receiving groove 121 arranged opposite to each other along the length direction of the iron ring 200 are the fifth end 1211 and the sixth end 1212, respectively. The two ends of the receiving groove 121 arranged opposite to each other along the thickness direction of the iron ring 200 are the seventh end 1213 and the eighth end 1214, respectively. The third spring piece... 412 can pass through the first clearance hole 122 and abut against the side of the iron ring 200 facing the fifth end 1211. The third spring 412 can push the iron ring 200 to move from the first initial position to the first fixed position along the second direction. The fourth spring 422 can pass through the second clearance hole 123 and abut against the side of the iron ring 200 facing the seventh end 1213. The fourth spring 422 can push the iron ring 200 to move from the first initial position to the first fixed position along the first direction. The iron ring 200 is located in the first fixed position. The two sides of the iron ring 200 arranged opposite each other along the second direction can abut against the third spring 412 and the sixth end 1212 respectively. The two sides of the iron ring 200 arranged opposite each other along the first direction can abut against the fourth spring 422 and the eighth end 1214 respectively. Specifically, as shown... Figure 3As shown, in this embodiment, the length direction of the iron ring 200 is the left-right direction, and the thickness direction of the iron ring 200 is the front-back direction. The third spring piece 412 can pass through the first clearance hole 122 and abut against the side of the iron ring 200 facing the fifth end 1211. After the iron ring 200 is installed in the receiving groove 121, if its first initial position is biased towards the fifth end 1211, the third spring piece 412 will be compressed to generate an elastic restoring force, pushing the iron ring 200 relative to the material box 1 towards the direction closer to the sixth end 1212, until it fits against the sixth end 1212, realizing the single-sided reference close in the length direction; the fourth spring piece 422 can pass through the second clearance hole 123 and abut against the side of the iron ring 200 facing the seventh end 1213, pushing the iron ring 200 towards the direction closer to the eighth end 1214 in the same mechanism, so that it fits against the eighth end 1214, realizing precise positioning in the thickness direction. Through this structure, the third spring 412 and the first pressure plate 411, and the fourth spring 422 and the second pressure plate 421 respectively constitute elastic pushing units. The deformation and restoring force of the springs automatically eliminate the assembly gap of the iron ring 200 within the receiving groove 121, allowing the iron ring 200 to move from the first initial position to the first fixed position, ensuring its stable and repeatable position in the material box 1. The first pressure plate 411 and the second pressure plate 421 are connected to the material box 1, not only fixing the springs but also restricting their direction of movement, ensuring the accuracy and stability of the thrust transmission. This two-stage positioning structure effectively solves the problems of robotic arm deviation and collision risk caused by the floating of the iron ring 200 within the material box 1, improving operational reliability. Simultaneously, during equipment operation or transportation, the elastic pressing effect of the springs suppresses the shaking and impact of the iron ring 200 caused by vibration, reducing noise and the risk of wafer cores detaching from the blue film. The overall structure is simple and compact, requires no external drive, responds quickly, is easy to maintain, and significantly improves the positioning accuracy and stability of the iron ring 200 in the semiconductor tooling system.

[0064] Please see Figures 6 to 9In one embodiment, the third positioning component 41 further includes a fifth spring 413. The fourth spring 422 and the fifth spring 413 are located at the fifth end 1211 and the sixth end 1212, respectively. The fifth spring 413 is connected to the first pressure plate 411. The fifth spring 413 can pass through the first clearance hole 122 and abut against the side of the iron ring 200 facing the seventh end 1213. The fifth spring 413 can push the iron ring 200 to move from the first initial position to the first fixed position along the first direction. The iron ring 200 is located at the first fixed position. One side of the iron ring 200 along the first direction can abut against the fourth spring 422 and the fifth spring 413, and the other side of the iron ring 200 along the first direction can abut against the eighth end 1214. Specifically, the fourth spring 422 and the fifth spring 413 are located at the fifth end 1211 and the sixth end 1212 of the receiving groove 121, which are arranged opposite each other along the length direction of the iron ring 200. Both are arranged corresponding to the force-bearing side of the iron ring 200 in the thickness direction. Both the fourth spring plate 422 and the fifth spring plate 413 abut against the side of the iron ring 200 facing the seventh end 1213, and simultaneously push the iron ring 200 relative to the material box 1 towards the eighth end 1214, so that it fits against the groove wall of the eighth end 1214, achieving single-sided reference clamping in the thickness direction. By setting the fourth spring plate 422 and the fifth spring plate 413 at both ends in the length direction, the iron ring 200 is pushed synchronously at two points in the thickness direction, effectively avoiding the tilting, twisting or local stress concentration of the iron ring 200 caused by uneven force during single-sided pushing, ensuring a smooth and reliable clamping process, and improving positioning consistency. This structure not only eliminates the assembly gap between the iron ring 200 and the receiving groove 121 in the thickness direction, but also significantly suppresses the shaking and impact of the iron ring 200 caused by vibration during equipment operation or transportation, reducing noise and the risk of wafer cores falling off the blue film. By combining the positioning function of the third spring 412 in the length direction, high-precision and stable positioning of the iron ring 200 within the material box 1 is achieved. The overall structure requires no external drive, offers rapid response, and high reliability, making it suitable for tooling scenarios in semiconductor sorting processes where strict attitude control of the iron ring 200 is required. Additionally, it should be noted that... Figure 6As shown, the third spring 412 includes a first elastic body and a first connecting plate. Both the first elastic body and the fifth spring 413 are connected to the first connecting plate. The first elastic body can pass through the first clearance hole 122 and abut against the side of the iron ring 200 facing the fifth end 1211. The first connecting plate is located between the first pressure plate 411 and the material box 1, and the first pressure plate 411, the first connecting plate and the material box 1 can be connected and fixed by the first bolt. The fourth spring 422 includes a second elastic body and a second connecting plate that are connected to each other. The second elastic body can pass through the second clearance hole 123 and abut against the side of the iron ring 200 facing the seventh end 1213. The second connecting plate is located between the second pressure plate 421 and the material box 1, and the second pressure plate 421, the second connecting plate and the material box 1 can be connected and fixed by the second bolt. Both the third spring 412 and the fourth spring 422 can be assembled by shearing, stamping or welding.

[0065] In this embodiment, the first spring 311, the second spring 321, the third spring 412, the fourth spring 422 and the fifth spring 413 can be reasonably selected in terms of material, thickness and geometric dimensions (such as length, width and curvature) to precisely control the magnitude of their elastic restoring force and ensure that a moderate thrust is generated when the material box 1 and the iron ring 200 are placed in.

[0066] Please see Figure 1 , Figure 10 and Figure 12 In one embodiment, both the first positioning component 31 and the second positioning component 32 are connected to the positioning base 2, and both can abut against the material box 1. Specifically, the first positioning component 31 and the second positioning component 32 are directly fixed to the positioning base 2, forming a stable installation foundation and avoiding positioning drift or structural loosening caused by floating settings. The first positioning component 31, by abutting against the material box 1, pushes the material box 1 to move in the first direction and fit against the second end 212 of the limiting groove 21, eliminating the assembly gap between the material box 1 and the limiting groove 21. The second positioning component 32, by abutting against the material box 1, pushes the material box 1 to move in the second direction and fit against the third end 213, realizing two-dimensional constraint of the material box 1 in the plane. Since both positioning components are rigidly connected to the positioning base 2, the applied thrust path is short and the transmission efficiency is high, ensuring that the material box 1 can automatically center and reach a highly consistent spatial position after each installation, significantly improving positioning repeatability.

[0067] Please see Figure 1 , Figure 10 and Figure 12In one embodiment, the material box 1 includes a bottom frame 11 and a side panel 12. The bottom frame 11 is connected to the side panel 12, and the side panel 12 is provided with a receiving groove 121. The first positioning component 31 and the second positioning component 32 can both abut against the bottom frame 11, or the first positioning component 31 and the second positioning component 32 can both abut against the side panel 12. Specifically, the side panel 12 is composed of four side plates connected in sequence. The two opposite side plates are provided with receiving grooves 121 for accommodating the iron ring 200. When the material box 1 is in use, the bottom frame 11 can be placed into the limiting groove 21 of the positioning base 2 as the bearing surface according to actual needs. At this time, the opening 1215 of the receiving groove 121 faces upward, which is suitable for conventional work stations. Alternatively, either side plate can be placed into the limiting groove 21 as the bearing surface. At this time, the opening 1215 of the receiving groove 121 faces to the side, which is suitable for space-constrained or side-loading processes. Regardless of the structure or installation posture of the material box 1, the first positioning component 31 and the second positioning component 32 are both located on the positioning base 2, and both achieve pushing and fitting by abutting against the current bearing surface of the material box 1 (bottom frame 11 or side plate of the groove), eliminating assembly gaps, ensuring that the material box 1 is installed in the same position each time, and avoiding collisions or posture deviations when the robot arm picks up and puts down the iron ring 200.

[0068] Please see Figure 1 and Figure 3 When the first spring piece 311 is used as the first positioning component 31, one end of the first spring piece 311 is fixed to the first end 211 of the limiting groove 21 along the first direction, and the other end extends into the groove; when the bottom frame 11 enters the groove, the other end of the first spring piece 311 abuts against the side of the bottom frame 11 facing the first end 211; when the side plate enters the groove, the other end of the first spring piece 311 abuts against the side of the side plate facing the first end 211, and the elastic restoring force of the first spring piece 311 pushes the material box 1 to move towards the second end 212, so that it fits against the groove wall of the second end 212, realizing the single-sided reference tightness in the first direction. Specifically:

[0069] Please see Figures 10 to 12 When the first elastic reset member 312 and the first abutting member 313 are used as the first positioning component 31, one end of the first elastic reset member 312 is connected to the first end 211 of the limiting groove 21, and the other end is connected to the first abutting member 313. The first abutting member 313 abuts against the bottom frame 11 or the side plate of the groove of the material box 1, thus realizing the pushing function.

[0070] The structure and function of the second positioning component 32 in the second direction are similar to those of the first positioning component 31. For example, the second spring piece 321 or the second elastic reset member 322 is combined with the second abutment member 323 to push the material box 1 to fit against the fourth end 214 in the second direction.

[0071] Please see Figures 13 to 15 In one embodiment, both the first positioning component 31 and the second positioning component 32 are connected to the material box 1, and both the first positioning component 31 and the second positioning component 32 can abut against the positioning base 2. Specifically, this structure integrates the positioning function into the body of the material box 1, so that the first positioning component 31 and the second positioning component 32 are installed together with the material box 1 into the limiting groove 21 of the positioning base 2. When the material box 1 is installed into the limiting groove 21 of the positioning base 2, the first positioning component 31 abuts against the first end 211 of the limiting groove 21, and generates an elastic restoring force towards the second end 212 after being pressed, pushing the material box 1 relative to the positioning base 2 in the first direction until the body of the material box 1 is in contact with the second end 212 of the limiting groove 21, realizing the one-sided reference in the first direction is close together; similarly, the second positioning component 32 abuts against the third end 213 of the limiting groove 21, and pushes the material box 1 towards the fourth end 214 through the same mechanism, so that it is in contact with the fourth end 214, completing the precise positioning in the second direction. This process effectively eliminates the assembly gap between the material box 1 and the limiting groove 21, ensuring consistent position height after each installation and significantly improving positioning repeatability. Furthermore, because the positioning component directly abuts against the rigid base, a stable force-closed path is formed, effectively eliminating the assembly gap between the material box 1 and the limiting groove 21, ensuring consistent position height after each installation, and improving positioning repeatability. This integrated positioning design of the material box 1 significantly improves the versatility and maintainability of the tooling system, making it suitable for automated equipment with high positioning stability requirements, such as semiconductor sorting and testing.

[0072] Please see Figures 13 to 15 In one embodiment, the material box 1 includes a bottom frame 11 and a side panel 12. The bottom frame 11 is connected to the side panel 12, and the side panel 12 is provided with a receiving groove 121. The first positioning component 31 and the second positioning component 32 can both be connected to the bottom frame 11, or both can be connected to the side panel 12. Specifically, regardless of the structure or installation posture of the material box 1, the first positioning component 31 and the second positioning component 32 can be selectively installed on the bottom frame 11 or either side panel, and both abut against the positioning base 2. When the material box 1 is installed into the positioning base 2, the first positioning component 31 abuts against the first end 211 of the limiting groove 21 along the first direction, effectively eliminating the assembly gap between the material box 1 and the limiting groove 21, ensuring that the spatial position height of the material box 1 is consistent after each installation, and significantly improving positioning repeatability. Specifically:

[0073] When the first spring piece 311 is used as the first positioning component 31, one end of the first spring piece 311 is fixed to the bottom frame 11 or the side panel 12 of the material box 1, and the other end extends toward the outside of the material box 1. In the installation mode where the bottom frame 11 is inserted into the groove, the other end of the first spring piece 311 abuts against the first end 211 of the positioning base 2. In the installation mode where the side panel is inserted into the groove, the other end of the first spring piece 311 still abuts against the first end 211, and the material box 1 is pushed toward the second end 212 by the same mechanism.

[0074] Please see Figures 13 to 15 When the first elastic reset member 312 and the first abutting member 313 are combined, one end of the first elastic reset member 312 is connected to the bottom frame 11 or the side panel 12 of the material box 1, and the other end is connected to the first abutting member 313. The first abutting member 313 abuts against the first end 211 of the positioning base 2, thus realizing the transmission of reverse pushing force.

[0075] The structure and function of the second positioning component 32 in the second direction are similar to those of the first positioning component 31. For example, the second spring piece 321 or the second elastic reset member 322 is combined with the second abutment member 323 to push the material box 1 to complete the single-sided clamping in the second direction.

[0076] Please see Figure 3 , Figure 7 and Figure 15In one embodiment, the number of first positioning components 31 is at least one, and the number of second positioning components 32 is at least one; and / or, the number of iron rings 200 is multiple, the number of limiting grooves 21 is consistent with the number of iron rings 200 and is set one-to-one, the number of third positioning components 41 is consistent with the number of iron rings 200 and is set one-to-one, and the number of fourth positioning components 42 is consistent with the number of iron rings 200 and is set one-to-one; specifically, each limiting groove 21 is configured with a set of independent third positioning components 41 and fourth positioning components 42 to achieve a consistent and one-to-one precise matching. This one-to-one correspondence setting allows each iron ring 200 to independently complete the positioning process of pushing, fitting, and pressing in the length and thickness directions without interference. This ensures the high consistency of the posture of each iron ring 200 and supports the mixed assembly or multi-station synchronous operation of iron rings 200 of different specifications. Combined with the positioning mechanism of the material box 1, the overall tooling system achieves dual precise positioning control from macro to micro. In this embodiment, the number of limiting grooves 21, third spring pieces 412, fourth spring pieces 422, fifth spring pieces 413, first clearance holes 122, and second clearance holes 123 are consistent with the number of iron rings 200 and are arranged in a one-to-one correspondence. All third spring pieces 412 and fifth spring pieces 413 are connected to the first pressure plate 411, and all fourth spring pieces 422 are connected to the second pressure plate 421. Furthermore, in this embodiment, the number of first positioning components 31 and second positioning components 32 can be flexibly configured according to actual needs; this embodiment does not limit this, to adapt to material boxes 1 of different sizes, weights, or precision requirements. Specifically:

[0077] Please see Figure 3 When there is only one first positioning component 31 and one second positioning component 32, to prevent the material box 1 from tilting or twisting due to force eccentricity during the pushing process, at least one positioning component should be located in the middle of its corresponding working end face. For example, the position of the second positioning component 32 is not limited, and the first positioning component 31 is located in the middle of the first end 211 of the limiting groove 21, the bottom frame 11 of the material box 1, or the side plate of the material box 1, to ensure that the pushing force passes through the center of gravity area of ​​the material box 1 and prevents rotation around the second direction; or the first positioning component 32 .... The position of component 31 is not limited. The second positioning component 32 is located at the third end 213 of the limiting groove 21 or at the middle position of the bottom frame 11 of the material box 1 or the side plate of the material box 1, to achieve a similar anti-deviation effect; or the first positioning component 31 is located at the first end 211 of the limiting groove 21 or at the middle position of the bottom frame 11 of the material box 1 or the side plate of the material box 1, and the second positioning component 32 is located at the third end 213 of the limiting groove 21 or at the middle position of the bottom frame 11 of the material box 1 or the side plate of the material box 1, with double midpoint force applied to achieve optimal balance.

[0078] Please see Figures 13 to 15When there are multiple first positioning components 31 and second positioning components 32, the multiple first positioning components 31 are arranged at intervals along the second direction at the first end 211 of the limiting groove 21 or the bottom frame 11 or the side plate of the material box 1, and the multiple second positioning components 32 are arranged at intervals along the first direction at the third end 213 of the limiting groove 21 or the bottom frame 11 or the side plate of the material box 1, forming a multi-point collaborative pushing structure. Through multi-point force distribution, local stress is effectively dispersed, avoiding structural deformation or sliding jamming caused by single-point concentrated load, and significantly improving the stability and positioning consistency of the pushing process.

[0079] Please see Figure 3 In this embodiment, a single first positioning component 31 is positioned at the middle of the first end 211 to ensure that the thrust line passes through the central area of ​​the material box 1, preventing it from deflecting during movement. A single second positioning component 32 is positioned at the edge of the third end 213. Although the second positioning component 32 is offset, the overall torque balance is still maintained because the first positioning component 31 is located at the midpoint, achieving stable propulsion and fit. This configuration simplifies the structure and saves space while ensuring positioning reliability, making it suitable for equipment environments with special restrictions on installation layout. In this embodiment, the positioning base 2 includes a base plate 22, a mounting frame 23, and four limiting blocks 24 disposed on the base plate 22. The four limiting blocks 24 are located at the four corners of the base plate 22, forming a positioning area for accommodating the material box 1. When the material box 1 is inserted, its outer periphery cooperates with the inner sidewalls of the four limiting blocks 24 to achieve initial positioning and anti-tipping constraint of the material box 1 in the horizontal plane, ensuring that the material box 1 does not shift or rotate significantly during insertion. The first positioning component 31 and the second positioning component 32 can be selectively set on any one or more limit blocks 24, or on the mounting bracket 23, according to actual working conditions.

[0080] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
