Description

Technical Field

[0001] This utility model relates to the technical field of integrated circuits, and in particular to a mold fixture based on a stable base transmission function. Background Technology

[0002] In the electronics manufacturing industry, the separation process of printed circuit board (PCB) assemblies is a common step, especially in the production of boards with V-cut or stamp-hole designs. Currently, the technical methods commonly used in the industry have significant drawbacks. One common method is to use old-fashioned base pins for fixation. Operators must manually place the PCBA board on the base and then rely on the pins to align with the positioning holes on the PCBA for fixation. This method has obvious disadvantages. Because it is a single-board operation and the positioning and fixing steps are cumbersome and time-consuming, the overall separation efficiency is low, making it difficult to meet the efficiency requirements of modern production. Furthermore, relying solely on positioning holes for fixation results in a small contact area and poor stability. When the separation equipment applies shearing or punching pressure, the PCBA board is easily loosened or shifted due to uneven force, even leading to component damage or PCB breakage, resulting in a high product scrap rate and increasing production costs and quality risks. Utility Model Content

[0003] This utility model provides a mold fixture based on a stable base conveying function, which aims to solve the problem of low board assembly and disassembly efficiency of PCBA board mounting fixtures in existing technical methods.

[0004] This utility model discloses a mold fixture based on a stable base conveying function for PCBA board processing. It includes a mounting plate, a cover plate, a stable base, and a conveyor. The mounting plate is disposed on the stable base, and its upper surface has a placement portion on which the PCBA board to be processed is placed. One end of the cover plate is connected to the stable base via a hinge, and the cover plate closes onto the placement portion and covers the PCBA board. An adjustable fixing buckle is provided on the upper surface of the mounting plate, and the fixing buckle engages with the side wall of the cover plate to fix it. The bottom end of the stable base is mounted on the conveyor, and the conveyor's conveying track continuously conveys the PCBA board towards a predetermined processing position on the PCBA board processing machine.

[0005] Furthermore, the placement part is configured as a groove, and a sliding auxiliary piece is provided on the inner wall of the placement part. The sliding auxiliary piece has a smooth surface and is arranged in a vertical direction. The PCBA board slides into the placement part through the sliding auxiliary piece.

[0006] Furthermore, a positioning protrusion is provided on the bottom surface of the mounting part, and the positioning protrusion corresponds to a preset positioning point on the PCBA board. The PCBA board is positioned and snapped in accordance with the alignment of the positioning protrusion and the positioning point.

[0007] Furthermore, a soft buffer protrusion is provided on the surface of the cover plate facing the PCBA board, and the soft buffer protrusion abuts against the upper surface of the PCBA board.

[0008] Furthermore, the mounting plate is provided with a plurality of mounting portions, and the mounting portions are combined to form a mounting module, which simultaneously mounts a plurality of PCBA boards to be processed.

[0009] Furthermore, multiple fixing buckles are provided, with fixing buckles provided in all four directions of the placement part, and each fixing buckle is provided in accordance with the axis of symmetry of the placement part.

[0010] Furthermore, a rotation buffer is provided on the movable hinge, and the rotation buffer is disposed between the movable hinge and the mounting plate to control the movement angle of the movable hinge.

[0011] Furthermore, a transmission interruption sensor is provided on the stable base. The transmission interruption sensor is connected to the movable hinge. When the movable hinge is in the open state and the cover plate is not closed on the mounting part, the transmission interruption sensor is activated and controls the transmitter to interrupt transmission.

[0012] This solution utilizes a "placement module" to simultaneously accommodate multiple PCBA boards, coupled with a "stable base conveyor function," enabling parallel processing of multiple boards. While one board is being processed, the next board can be prepared and secured at an adjacent workstation. The conveyor function ensures that the fixtures automatically and continuously reach the processing station, significantly reducing waiting and handling time. This fundamentally solves the inefficiency problem caused by single-board operation, greatly improving production cycle time. Attached Figure Description

[0022] like Figure 1 as well as Figure 2As shown, this embodiment provides a mold fixture based on a stable base conveying function for processing PCBA board 4, including a mounting plate, a cover plate 1, a stable base 2, and a conveyor; the mounting plate is disposed on the stable base 2, and the upper surface of the mounting plate is provided with a placement part 3, on which the PCBA board 4 to be processed is placed; one end of the cover plate 1 is connected to the stable base 2 through a movable hinge 5, and the cover plate 1 covers the placement part 3 and covers the PCBA board 4; the upper surface of the mounting plate is provided with a movable and adjustable fixing buckle 6, which is fastened to the side wall of the cover plate 1 to fix the cover plate 1; the bottom end of the stable base 2 is mounted on the conveyor, and the conveyor's conveying track continuously conveys the PCBA board towards the preset processing position of the PCBA board processing machine.

[0023] In practical applications, firstly, a dedicated mold fixture is precisely manufactured based on the PCB file (Gerber file, etc.) of the PCBA board 4 to be separated. The key to this fixture is its "placement part 3," which precisely matches the shape, size, and positioning hole positions of the PCBA board 4 with grooves or positioning posts. The operator carefully places the PCBA board 4 to be separated into the "placement part 3" of the fixture. Because the "placement part 3" is customized according to the PCB file, the PCBA board 4 is automatically and precisely positioned without the need for additional searching or alignment. The fixture with the PCBA board 4 is then installed onto the stabilizing base 2. The mounting plate is fixed to the stabilizing base 2, ensuring the entire fixture structure is stable. The operator opens the cover plate 1 via the movable hinge 5 and places it over the PCBA board 4. The cover plate 1 is designed to increase the contact area and pressure, ensuring that the PCBA board 4 does not move during the separation process. The adjustable retaining clips 6 on the mounting plate are adjusted to engage with the side wall of the cover plate 1. The function of the retaining clip 6 is to apply pressure, firmly pressing the cover plate 1 in place, thereby securely pressing the PCBA board 4 into the mounting section 3. This double fixation (positioning of the mounting section 3 + pressure from the cover plate 1 and retaining clip 6) ensures the absolute stability of the PCBA board 4 during the subsequent separation process. After confirming that the PCBA board 4 is securely fixed, the entire fixture (mounting plate, cover plate 1, stabilizing base 2, and PCBA board 4) is assembled as a whole, with the stabilizing base 2 at its bottom mounted (or placed) on the conveyor. The conveyor starts and continuously and smoothly transports the fixture along the preset conveyor track to the processing station of the separation equipment (such as a V-cut separation machine, laser cutting machine, etc.). At the processing station, the separation equipment automatically identifies the position of the fixture (possibly through sensors or preset coordinates) and then performs the separation operation. Since the PCBA board 4 has been securely fixed by the fixture, the separation process can be carried out quickly and accurately, with almost no vibration or displacement. After the board separation is completed, the conveyor continues to transport the fixture with the separated PCBA board 4 to the next station (such as the collection area, inspection area, etc.), or directly transports it away, freeing up space for the next PCBA board 4. The operator can start the next cycle, placing the new PCBA board 4 into the fixture, repeating the process of fixing, conveying, and separating the board. This greatly improves work efficiency and solves the time-consuming problem of the old-style base pin fixing. Traditional pin fixing requires aligning each pin with the positioning hole of the PCBA one by one, which is cumbersome and time-consuming. This solution achieves automatic positioning through the "placement part 3" of the special fixture, greatly shortening the loading time. The design of the fixing buckle 6 and cover plate 1 is also faster than manually tightening multiple pins. The conveyor automatically transports the fixture to the separation station, saving the time of manual handling and placement, realizing a semi-automatic or automatic process from loading, fixing to separation, and significantly speeding up the overall operation cycle. With traditional pin fixing, especially when the board is under stress during separation, the PCBA board 4 is prone to slight displacement or vibration, resulting in inaccurate cutting, edge burrs, or even damage to components, causing product scrap.This solution provides precise initial positioning through a customized "placement section 3," which, combined with the uniform pressure applied by the cover plate 1 and adjustable fixing buckles 6, forms a rigid clamping system. This ensures the absolute stability of the PCBA board 4 during the separation process, virtually eliminating the risk of loosening and significantly reducing product scrap rates. The customized fixture guarantees that the PCBA board 4 is in the exact same initial position each time. Combined with the precise positioning of the conveyor, this allows the separation equipment to cut at the same location every time, improving the consistency and accuracy of separation. The operator simply places the PCBA board 4 into the fixture, closes the cover plate 1, and fastens the fixing buckles 6, then places it on the conveyor. The process is simple and standardized, reducing reliance on operator skills and errors caused by human error. Although dedicated fixtures need to be made for different PCBA boards 4, once the fixtures are made, this solution can reliably and efficiently handle a large number of PCBA boards 4 of the same model for separation.

[0024] In summary, this design is naturally suited for further automation. An automated loading robot arm can be designed to place the PCBA board 4 into the fixture, automatically close the cover plate 1 and lock the fixing buckle 6. Even an automated fixture changing system can be designed to adapt to the production needs of multiple varieties and small batches. The conveying function is fundamental to achieving an automated production line. Customized design solves the core pain points of low efficiency and poor stability in traditional methods. It not only significantly improves the efficiency of PCBA board separation operations, but more importantly, greatly enhances the stability of the processing and the product yield, while reducing production risks and costs. At the same time, its structural design lays a solid foundation for achieving a higher degree of automated production in the future, possessing high practical value and market potential.

[0025] Furthermore, the placement part 3 is configured as a groove, and a sliding auxiliary piece is provided on the inner wall of the placement part 3. The sliding auxiliary piece has a smooth surface and is arranged in the up-down direction. The PCBA board 4 slides into the placement part 3 through the sliding auxiliary piece.

[0026] Furthermore, a positioning protrusion 7 is provided on the bottom surface of the placement part 3. The positioning protrusion 7 corresponds to a preset positioning point on the PCBA board 4. The PCBA board 4 is positioned and snapped in accordance with the docking of the positioning protrusion 7 and the positioning point.

[0027] Specifically, a dedicated mold fixture is precisely manufactured based on the PCB file of the PCBA board 4 to be separated. This time, the placement section 3 is designed as a "slot," with "sliding auxiliary pieces" specially provided on its inner wall. These sliding auxiliary pieces have smooth surfaces and are arranged vertically (perpendicular to the bottom of the slot). Furthermore, "positioning protrusions 7" are provided on the bottom surface of the placement section 3, precisely corresponding to the preset positioning points on the PCBA board 4. The operator aligns the edge of the PCBA board 4 to be separated with the opening of the slot-shaped placement section 3. The PCBA board 4 is not placed directly, but rather slides into the placement section 3 via the sliding auxiliary pieces. Due to the smooth surface of the sliding auxiliary pieces, the PCBA board 4 can slide smoothly and easily into the slot, reducing the risk of deformation of the PCBA board 4 or damage to internal components that might result from the operator pressing too hard. When the PCBA board 4 slides into the slot-shaped placement section 3, its preset positioning points at the bottom automatically find and align with the positioning protrusions 7 on the bottom surface of the placement section 3. Once aligned successfully, the PCBA board 4 is precisely "positioned and snapped" into the placement section 3. This design ensures that the PCBA board 4 is accurately positioned not only laterally and longitudinally, but also has a defined reference point in the Z-axis (perpendicular to the board surface), providing a stable force point for the pressure applied by the cover plate 1. This is much more precise than simply relying on edges or simple grooves for positioning. The fixture with the precisely positioned PCBA board 4 is mounted onto the stabilizing base 2. The operator opens the cover plate 1 via the movable hinge 5 and places it over the PCBA board 4. Since the PCBA board 4 is already precisely positioned in the groove, the closing process of the cover plate 1 is smoother. The adjustable retaining clip 6 on the mounting plate is adjusted to engage with the side wall of the cover plate 1. The pressure applied by the retaining clip 6 is evenly transmitted to the PCBA board 4 through the cover plate 1, ensuring its absolute stability throughout the separation process and preventing movement due to cutting force. The fixture is placed on a conveyor, which continuously and stably transports the fixture to the pre-set processing position of the PCBA board 4 processing machine for separation. The PCBA board 4 is "slid in" rather than "placed in" or "pressed in" by sliding auxiliary plates, making the operation more labor-saving and faster. This advantage is particularly pronounced for larger or heavier PCBA boards 4. It directly addresses the pain point of "long processing time" in the original problem 1, improving work efficiency. The smooth sliding process avoids potential scratches on the edges of the PCBA board 4, stress on internal components, or damage to solder joints caused by rough placement. The "positioning snap-fit" mechanism of the positioning protrusions 7 provides accuracy far exceeding that of simple edge or hole positioning. It ensures that every position on the PCBA board 4 that needs to be cut can be reproduced in the depaneling equipment, greatly improving the straightness, perpendicularity, and consistency between different PCBA boards 4. This is crucial for the quality of subsequent depaneling processes. Enhancing stability and reliability during the depaneling process, precise positioning is the foundation of stability: because the PCBA board 4 is precisely and firmly "snapped" in the slot at the initial stage, the pressure applied by the cover plate 1 can more evenly and effectively fix the entire board.This dual protection (precise snap-fit ​​orientation pressure) ensures that PCBA board 4 is virtually impossible to shift or loosen when subjected to the cutting force of the depaneling equipment. Completely eliminating the risk of loosening directly and thoroughly resolves the original problem 2: "the risk of the board loosening during depaneling due to the pins directly fixing the PCBA's positioning holes, leading to product scrap." Positioning holes are typically small with limited force-bearing area, and pin fixing methods may suffer from uneven pressure or poor contact. This solution, through a large-area slotted contact and precise positioning protrusions 7, provides a more reliable and uniform fixing effect. Each PCBA board 4 is placed and fixed using the same method (sliding in) and the same reference (positioning protrusions 7), reducing positioning deviations caused by individual operator differences or varying operating habits, further ensuring stable product quality. These two added details perfectly complement and enhance the original solution. The slotted placement part 3 and the sliding auxiliary piece solve the problem of rapid, non-destructive placement, while the bottom positioning protrusions 7 provide unprecedented precision positioning capabilities. The combination of these two elements not only makes the placement and fixing of PCBA board 4 more efficient and convenient, but more importantly, they together form an extremely stable and reliable processing foundation. This fundamentally eliminates the risk of PCBA board 4 becoming loose and scrapped during the separation process, further improving overall production efficiency and product quality. This makes the technical solution more mature and competitive.

[0028] Furthermore, a soft buffer protrusion 8 is provided on the surface of the cover plate 1 facing the PCBA board 4, and the soft buffer protrusion 8 abuts against the upper surface of the PCBA board 4.

[0029] Furthermore, the mounting plate is provided with a plurality of the placement parts 3, and the placement parts 3 are combined to form a placement module, and the placement module simultaneously mounts a plurality of PCBA boards 4 to be processed.

[0030] Specifically, a dedicated mold fixture is precisely manufactured based on the PCB file of the PCBA board 4 to be separated. The mounting section 3 is still slot-shaped, with smooth sliding auxiliary plates on the inner wall and positioning protrusions 7 on the bottom surface corresponding to the PCBA positioning points. In particular, soft buffer protrusions 8” are evenly distributed on the surface of the cover plate 1 facing the PCBA board 4. In addition, the mounting plate no longer has only one mounting section 3, but multiple mounting sections 3 are provided. These mounting sections 3 are combined to form a "mounting module" that can accommodate multiple PCBA boards 4 to be processed at the same time. The operator (or automated equipment) aligns multiple PCBA boards 4 with their respective slot-shaped mounting section 3 openings and slides them in one by one through the sliding auxiliary plates. Each PCBA board 4 will precisely engage with the positioning protrusions 7 on the bottom, achieving fast and accurate positioning. When all PCBA boards 4 are in place, the cover plate 1 rotates downward through the movable hinge 5, covering the mounting module and covering all PCBA boards 4. The soft buffer protrusions 8” on the cover plate 1 will abut against the upper surface of the PCBA board 4. These protrusions, made of soft materials (such as silicone and rubber), apply a uniform and gentle pressure to the PCBA board 4 when the cover plate 1 locks in place with the retaining clip 6. This pressure not only firmly presses the PCBA board 4 into the slotted mounting section 3, preventing it from loosening due to vibration or cutting forces during the separation process, but more importantly, the soft material acts as a buffer and protector. It effectively disperses pressure, avoiding concentrated stress points on the surface of the PCBA board 4 (especially areas that may cover components or flexible circuits), preventing damage to the board surface or components. Since the mounting module on the mounting plate can simultaneously mount multiple PCBA boards 4, and each board is precisely positioned and securely fixed in the above manner, this fixture can load multiple PCBA boards 4 at once. Once the cover plate 1 is locked, the entire fixture (containing multiple PCBA boards 4) is transported as a whole to the processing station of the separating equipment by a conveyor mounted on the stable base 2. The equipment separates multiple PCBA boards 4 simultaneously or sequentially (depending on the capacity of the separating equipment). After separating, the fixture continues to be conveyed, possibly to the unloading station or cyclically back to the loading station. Multiple PCBA boards 4 are slid into their respective placement parts 3. The cover plate 1 is closed and locked, the soft protrusion contacts the surface of the PCBA board 4, and the locking buckle 6 is tightened. The fixture is then transported to the separating station. The sliding auxiliary plate allows the PCBA boards 4 to slide in quickly and easily without the need for strenuous alignment and pressing. The positioning protrusion 7 ensures high consistency and accuracy in every placement, reducing adjustment time.

[0031] The multi-board parallel placement module allows multiple PCBA boards 4 to be processed simultaneously. This significantly reduces the total time for a single board separation operation. Even with the same transfer and separation time, the number of products completed per unit time increases exponentially, resulting in an order-of-magnitude improvement in production efficiency. The triple-fixing mechanism of the slotted structure, positioning protrusions 7, and cover plate 1 ensures the absolute stability of the PCBA board 4 during separation, completely eliminating the risk of loosening. The soft buffer protrusions 8 provide pressure while effectively protecting the surface and components of the PCBA board 4, preventing damage caused by excessive pressure or poor contact, further improving product yield. Standardized placement and fixing processes ensure that each PCBA board 4 receives the same treatment, resulting in more stable and reliable product quality. By adding the soft buffer protrusions 8 and the multi-board placement module, this technical solution represents a qualitative leap forward. It not only perfectly solves the original technical problems but also reaches new heights in efficiency, stability, ease of operation, and automation potential. The soft bumps provide protective fixation, while multi-board processing elevates production efficiency to a whole new level, making this solution highly attractive and practical for modern electronics manufacturing, especially for scenarios requiring high-efficiency, high-yield production.

[0032] Furthermore, multiple fixing buckles 6 are provided, with fixing buckles 6 provided in all four directions of the placement part 3, and each fixing buckle 6 is provided in accordance with the axis of symmetry of the placement part 3.

[0033] Furthermore, a rotation buffer is provided on the movable hinge 5, and the rotation buffer is disposed between the movable hinge 5 and the mounting plate to control the movement angle of the movable hinge 5.

[0034] Furthermore, a transmission interruption sensor is provided on the stable base 2. The transmission interruption sensor is connected to the movable hinge 5. When the movable hinge 5 is in the open state, the cover plate 1 is not closed on the mounting part 3. The transmission interruption sensor is activated and controls the transmitter to interrupt transmission.

[0035] Specifically, the fixture's mounting plate is equipped with a mounting module consisting of multiple mounting sections 3, each of which is slot-shaped with a sliding auxiliary piece and a bottom positioning protrusion 7. A soft buffer protrusion 8 is provided on the inner side of the cover plate 1. Multiple retaining clips 6 are now set, evenly distributed along the four directions of the mounting sections 3, and they are arranged corresponding to the axes of symmetry of the mounting sections 3. A rotation buffer is also added to the movable hinge 5, installed between the hinge and the mounting plate. A transmission interruption sensor is integrated into the stabilizing base 2, which is connected to the state of the movable hinge 5. The operator (or automated equipment) slides multiple PCBA boards 4 into their respective mounting sections 3 and positions them. The cover plate 1 rotates downwards, closing onto the mounting module. Because the retaining clips 6 are symmetrically distributed in four directions, when the operator (or automated locking mechanism) engages these retaining clips 6, the cover plate 1 presses down evenly onto the PCBA boards 4. This symmetrical distribution design ensures that the pressure applied to the PCBA boards 4 is balanced, avoiding the risk of deformation of the PCBA boards 4 or damage to edge components due to excessive force on one side. The soft cushioning protrusion 8 provides pressure dispersion and protection. The rotating buffer plays a role during the rotation of the cover plate 1. It controls the opening and closing angle of the cover plate 1, providing a smooth and controlled rotation experience. This not only prevents the impact that may occur when the cover plate 1 falls rapidly due to gravity, protecting the PCBA board 4, but also makes the opening and stopping of the cover plate 1 more precise and gentle in automated applications, reducing mechanical wear. The transmission interruption sensor on the stabilizing base 2 continuously monitors the status of the movable hinge 5. The sensor is only triggered when the cover plate 1 is fully opened and the movable hinge 5 is in its set "open state". At this time, the sensor sends a signal to the control system to control the conveyor to interrupt transmission. This means that the fixture will only stop moving on the conveyor track when the cover plate 1 is fully open, ready for the placement or removal of the PCBA board 4. Conversely, once the cover plate 1 begins to close and the locking buckle 6 is tightened, the movable hinge 5 leaves the "open state", the sensor signal is released, and the conveyor can resume transmission, sending the installed and locked PCBA board 4 to the separation processing position.

[0036] The symmetrical fixing buckle 6 significantly improves the balance and safety of the fixing process, ensuring uniform force on the PCBA board 4, protecting the board and components, and providing a precise positioning reference for automated locking. The rotating buffer enhances the operating experience (whether manual or automated), protects the PCBA board 4 from impact damage, extends the service life of mechanical components such as hinges, and makes movements smoother and more controllable. The conveyor interruption sensor is an important safety and process control function. It ensures that the fixture only stops moving when in a safe state (cover 1 is open, allowing loading and unloading), preventing the risk of operation during conveying, and strictly defining the "loading complete, ready for conveying" node, making the entire production process more orderly and highly automated. These details make this mold fixture not only excellent in single-processing efficiency and stability, but also achieve a high level in overall production cycle time, operational safety, and system integration. It is easier to integrate into automated production lines, reducing human intervention and potential errors, further consolidating the superiority of this solution in solving original technical problems, making it a highly reliable and worthwhile solution to promote.

[0037] This utility model discloses a mold fixture based on a stable base conveying function for processing PCBA boards 4. It includes a mounting plate, a cover plate 1, a stable base 2, and a conveyor. The mounting plate is disposed on the stable base 2, and its upper surface has a placement portion 3 on which the PCBA board 4 to be processed is placed. One end of the cover plate 1 is connected to the stable base 2 via a hinge 5, and the cover plate 1 covers the placement portion 3 and the PCBA board 4. An adjustable fixing buckle 6 is provided on the upper surface of the mounting plate, and the fixing buckle 6 engages with the side wall of the cover plate 1 to fix it. The bottom end of the stable base 2 is mounted on the conveyor, and the conveyor's conveying track continuously conveys the PCBA board towards a preset processing position on the PCBA board processing machine. This solution simultaneously accommodates multiple PCBA boards 4 through a "placement module," and, in conjunction with the "stable base 2 conveying function," achieves parallel processing of multiple boards. While one board is being processed, the next board can be prepared and fixed simultaneously at an adjacent workstation. The conveying function ensures that the fixture can automatically and continuously reach the processing position, greatly reducing waiting and handling time. This fundamentally solves the inefficiency problem caused by single-board operation, and the production cycle is greatly improved. Addressing the issues of "easy loosening and high risk": a closed-loop guarantee of precise positioning and stable clamping. Existing technology relied on ejector pins to fix the positioning holes, resulting in a single force point. The separation force easily caused the board to move or deform, leading to high risk. The solution achieves rapid, precise, and stress-free positioning of the PCBA board 4 through "slot-shaped placement part 3 + sliding auxiliary piece + bottom positioning protrusion 7"; and stable clamping by applying pressure evenly from the board surface through "multiple symmetrically distributed fixing buckles 6 + soft buffer protrusions 8," rather than relying solely on positioning holes. This comprehensive and controlled fixing method is far more robust and reliable than single ejector pin fixing, completely eliminating the risk of product scrap due to board loosening or displacement during separation, and raising the yield rate to a new level. In summary, the core contribution of this solution is that it is no longer a simple improvement on existing methods, but rather provides a completely new and systematic solution. Through integrated innovation in hardware design (customization, multi-station, precision positioning, stable clamping, and automated conveying), it transforms the PCBA depaneling process from a labor-intensive and high-risk operation into an efficient, stable, and high-yield automated production process, perfectly solving the two core pain points of the original technical solutions.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
