Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessory testing, specifically a probe measuring mechanism for mobile phone back covers. Background Technology

[0002] In the manufacturing process of mobile phone battery back covers, arc height accuracy is one of the core parameters affecting the product's assembly sealing and appearance quality. Currently, the industry generally uses manual measurement, where operators need to use a height gauge to check the arc height at multiple preset points on the back cover surface point by point, and filter out out-of-tolerance products through visual comparison or manual data recording. However, with the accelerated pace of product iteration and the expansion of production scale, the traditional manual measurement method has revealed significant shortcomings.

[0003] Each product requires measurement at multiple points, and manual point-by-point operation is time-consuming and cumbersome, especially in mass production scenarios where it is difficult to meet the cycle time requirements. Differences in measurement techniques, force, and reading habits among different operators can easily introduce human error, resulting in large data dispersion and difficulty in unifying quality judgment standards. At the same time, manual recording relies on paper forms or scattered electronic spreadsheets, which poses risks of omissions and misrecordings. Furthermore, it is impossible to connect measurement results with MES in real time, leading to a break in the production quality data chain and making it difficult to optimize process parameters and analyze the root causes of defects. In addition, the new back cover design tends to have diversified curved shapes, increasing the need for dynamic adjustment of the number and distribution of measurement points. The traditional fixed measurement mode of height gauges cannot quickly adapt to different product models, and the changeover and debugging cycle is long, which restricts the flexible upgrading of the production line.

[0004] While some semi-automated measurement devices exist in existing technologies, they mostly employ single-point static detection or simple mechanical positioning structures, still facing problems such as difficulty in balancing detection speed and accuracy, poor adaptability to complex curved surfaces, and data silos. Therefore, there is an urgent need for an intelligent detection mechanism that integrates high-precision dynamic measurement, multi-dimensional data interaction, and flexible positioning functions to overcome existing technological bottlenecks and meet the demands of intelligent manufacturing for efficient, accurate, and traceable quality control.

[0005] A search revealed a Chinese patent document that discloses a probe measuring device [Application No.: 201921861530.X, Publication No.: CN211179939U]. This probe measuring device includes a base frame and an electrode clamp assembly mounted on the base frame, connected to a power source. The electrode clamp assembly includes a fixed clamp and a movable clamp. The movable clamp can move relative to the fixed clamp to abut against the workpiece placed on the fixed clamp. While this device can achieve the measurement objective, its complex structure makes it unsuitable for measuring mass-produced, structurally diverse products such as mobile phone back covers. Utility Model Content

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a probe measurement mechanism for mobile phone back cover.

[0007] A probe measuring mechanism for a mobile phone back cover, characterized in that: the probe measuring mechanism includes a fixed base, a measuring module, an upper detection component, and a lower detection component;

[0008] One side of the measurement module is mounted on a fixed base, and an upper detection component is movably mounted on the other side of the measurement module. A lower detection component is located directly below the upper detection component.

[0009] Preferably, the upper detection component and the lower detection component are in a mutually cooperating corresponding relationship.

[0010] Through the above technical solution, the cooperation between the upper and lower detection components enables them to precisely align during operation, thereby improving the consistency and reliability of the measurement process. This cooperation not only reduces errors caused by poor component alignment but also effectively avoids the accumulation of measurement errors, improving the accuracy of probe measurement. Specifically, the precise cooperation between the upper and lower detection components provides a more stable contact force and more accurate positioning when the probe contacts the object being measured, thus improving the accuracy of the measurement results.

[0011] Preferably, the fixed base includes a fixed plate, a stiffening plate, a vertical plate, and a module connector. The fixed plate and the vertical plate form an L-shaped structure. The fixed base is provided with a stiffening rib. The rear end face of the stiffening rib is installed on the vertical plate, and the bottom end face of the stiffening rib is installed on the fixed plate. The module connector is installed on the top of the vertical plate.

[0012] Through the above technical solutions, the design of the fixed base effectively avoids measurement errors caused by deformation, thereby improving the measurement accuracy and stability of the probe measurement mechanism. The L-shaped structure formed by the fixed plate and the upright plate enhances the stability of the entire base, providing more uniform support under stress and preventing uneven deformation of the base. The design of the reinforcing ribs plays a role in preventing base deformation in key parts, ensuring that the fixed base can maintain its original structural shape when used for a long time or subjected to external impact. The module connector is installed on the top of the upright plate, making the connection with other components more secure and ensuring the stability and measurement accuracy of the measurement module.

[0013] Preferably, the upper detection component includes a measurement module connector, a probe assembly, a probe positioning plate, a probe fixing plate, and an adjustment fixing block. The measurement module connector is movably mounted on the measurement module. The probe fixing plate has a probe positioning plate at its top and an adjustment fixing block at its bottom. The probe assembly is mounted through the probe fixing plate and the probe positioning plate. The probe assembly, the probe positioning plate, the probe fixing plate, and the adjustment fixing block together are mounted on the measurement module connector.

[0014] Through the above technical solution, a highly integrated and adjustable structure is formed. The measurement module connector is connected to the measurement module through movable installation, ensuring the flexibility and stability between components and allowing for appropriate adjustments according to different measurement needs. The top of the probe fixing plate is equipped with a probe positioning plate, which provides precise probe position adjustment and fixing functions to ensure the accuracy of the probe during the measurement process. The bottom adjustment fixing block plays a role in adjusting and stabilizing the position of the probe, further improving the accuracy and consistency of the measurement. The probe assembly is installed through the probe fixing plate and the probe positioning plate, forming a stable probe installation system that can effectively prevent the probe from shifting or loosening during the measurement process.

[0015] Preferably, the lower detection component is fixed on a plane.

[0016] The above technical solution effectively ensures stability and accuracy during the measurement process. The method of fixing the lower detection component, by firmly mounting it on a flat surface, provides reliable support to the lower part of the entire probe measurement mechanism, preventing any displacement or vibration caused by instability at the bottom.

[0017] Preferably, the upper tooling connecting block and the upper tooling relative to the adjustment fixing block on the upper and lower detection components are movably connected by a concave-convex structure.

[0018] The above technical solution effectively prevents structural jamming caused by machining and assembly errors when the downward inspection tooling is closed. The movable connection method of the concave-convex structure allows the upper tooling connecting block to maintain a certain degree of flexibility with the upper tooling. Even when there are slight dimensional errors between components, it can ensure that the upper tooling can smoothly dock with the lower tooling without jamming or blocking due to errors.

[0019] Preferably, both the upper and lower testing fixtures are inlaid with magnets, and the positions of the magnets are corresponding.

[0020] The above technical solution provides precise positioning during mold closing and generates downward pressure through magnetic force, thereby ensuring the accuracy of product measurement. During mold closing, the correspondence of the magnets allows the upper tooling to precisely align with the lower detection tooling, avoiding inaccurate or loose alignment caused by errors. At the same time, the magnets also provide a certain downward pressure, ensuring that the upper tooling can tightly fit the lower detection tooling during mold closing, thereby improving measurement accuracy.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This probe measuring mechanism, through its upper and lower detection components and magnet positioning and downward pressure design, ensures precise alignment between tooling components during mold closing. This precise fit avoids measurement errors caused by inaccurate component alignment, while the downward pressure provided by the magnet helps stabilize the tooling position, reducing the impact of external vibrations or interference on the measurement results. Through these innovative designs, this probe measuring mechanism can maintain high-precision measurements during long-term operation, meeting high-standard measurement requirements and ensuring the accuracy and consistency of measurement data.

[0023] 2. The probe measuring mechanism has a compact and modular structure, which enables the components to be assembled quickly and stably, greatly improving production efficiency. The assembly process is simple and highly tolerant, and it can adapt to different manufacturing tolerances, reducing the complexity and cost of the production process. This makes it very suitable for large-scale mass production and meets industrial needs. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 3 This utility model provides a technical solution:

[0030] A probe measuring mechanism for a mobile phone back cover, characterized in that: the probe measuring mechanism includes a fixed base 1, a measuring module 2, an upper detection component 3 and a lower detection component 4;

[0031] One side of the measuring module 2 is mounted on the fixed base 1, and the upper detection component 3 is movably mounted on the other side of the measuring module 2. The lower detection component 4 is located directly below the upper detection component 3.

[0032] Specifically, the upper detection component 3 and the lower detection component 4 are in a mutually cooperating relationship. This cooperation allows them to precisely align during operation, thereby improving the consistency and reliability of the measurement process. This cooperation not only reduces errors caused by poor component alignment but also effectively avoids the accumulation of measurement errors, improving the accuracy of probe measurements. Specifically, the precise cooperation between the upper and lower detection components provides a more stable contact force and more accurate positioning when the probe contacts the object being measured, thus improving the accuracy of the measurement results. By adopting this optimization scheme, the overall performance of the probe measurement mechanism is significantly improved, and its adaptability is also enhanced. In the measurement of complex objects or micro-parts, this cooperation can minimize errors and ensure the reliability of the measurement results.

[0033] Specifically, the fixed base 1 includes a fixed plate 101, a stiffening plate 102, a vertical plate 103, and a module connector 104. The fixed plate 101 and the vertical plate 103 form an L-shaped structure. The fixed base 1 is provided with a reinforcing rib. The rear end face of the reinforcing rib is installed on the vertical plate 103, and the bottom end face of the reinforcing rib is installed on the fixed plate 101. The module connector 104 is installed on the top of the vertical plate 103. The design of the fixed base 1 effectively avoids measurement errors caused by deformation, thereby improving the measurement accuracy and stability of the probe measurement mechanism. The L-shaped structure formed by the fixed plate 101 and the vertical plate 103 enhances the stability of the entire base and can provide more uniform support when under force, preventing uneven deformation of the base. The design of the reinforcing rib plays a role in preventing base deformation in key parts, ensuring that the fixed base 1 can maintain its original structural shape when used for a long time or subjected to external impact. The module connector 104 is installed on the top of the vertical plate 103, making the connection with other components more secure and ensuring the stability and measurement accuracy of the measurement module 2.

[0034] Specifically, the upper detection component 3 includes a measurement module connector 301, a probe assembly 302, a probe positioning plate 303, a probe fixing plate 304, and an adjustment fixing block 305. The measurement module connector 301 is movably mounted on the measurement module 2. The probe fixing plate 304 has the probe positioning plate 303 on its top and the adjustment fixing block 305 on its bottom. The probe assembly 302 is mounted through the probe fixing plate 304 and the probe positioning plate 303. The probe assembly 302, the probe positioning plate 303, the probe fixing plate 304, and the adjustment fixing block 305 are mounted as a whole on the measurement module connector 301, forming a highly integrated and adjustable structure. The measurement module connector 301 is connected to the measurement module 2 via a movable mounting, ensuring flexibility and stability between components and allowing for appropriate adjustments according to different measurement needs. The probe fixing plate 304 has a probe positioning plate 303 on its top, providing precise probe position adjustment and fixing functions to ensure the accuracy of the probe during the measurement process. The adjustment fixing block 305 at the bottom plays a role in adjusting and stabilizing the position of the probe, further improving the accuracy and consistency of the measurement. The probe assembly 302 is installed through the probe fixing plate 304 and the probe positioning plate 303, forming a stable probe installation system that can effectively prevent the probe from shifting or loosening during the measurement process.

[0035] All these components, combined and connected to the upper detection component 3 via the measurement module connector 301, enable the entire system to possess extremely high precision and stability. This design not only ensures accurate probe positioning and stable measurement but also improves the accuracy and reliability of measurement results by optimizing the flexibility of the measurement process through functional adjustments.

[0036] Specifically, the lower detection component 4 is fixed to a flat surface, effectively ensuring stability and accuracy during the measurement process. By securely mounting the lower detection component 4 to the flat surface, the lower part of the entire probe measurement mechanism is reliably supported, preventing any displacement or vibration caused by instability at the bottom. The flat-surface fixing design enhances the synergy between the lower detection component 4 and other components, improving measurement accuracy.

[0037] Specifically, the upper tooling connecting block and the upper tooling relative to the adjusting and fixing block 305 on the upper detection component 3 and lower detection component 4 are connected by a concave-convex structure. This effectively prevents structural jamming caused by machining and assembly errors when the lower detection tooling is closed. The concave-convex structure allows for a certain degree of flexibility between the upper tooling connecting block and the upper tooling. Even with minor dimensional errors between components, the upper tooling can smoothly dock with the lower tooling without jamming or blocking due to errors. This movable connection design effectively eliminates the impact of machining and assembly errors, avoiding the risk of measurement failure or equipment damage caused by components failing to close smoothly during the measurement process.

[0038] Specifically, both the upper and lower inspection fixtures are embedded with magnets, which are positioned in a corresponding relationship. This provides precise positioning during mold closing and generates downward pressure through magnetic force, thereby ensuring the accuracy of product measurement. During mold closing, the correspondence of the magnets allows the upper fixture to precisely align with the lower inspection fixture, avoiding inaccurate or loose alignment caused by errors. At the same time, the magnets also provide a certain downward pressure, ensuring that the upper fixture fits tightly against the lower inspection fixture during mold closing, thereby improving measurement accuracy. This downward pressure helps maintain the stability of the fixture during the measurement process and prevents inaccurate measurement results due to external interference.
