Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a faceplate positioning mechanism. Background Technology

[0002] In the current mobile phone manufacturing industry, the positioning and fixing of the phone casing is one of the crucial steps in the production process. Currently, the positioning of phone casings mostly uses pins combined with suction cups. However, this method has revealed a series of problems in practical applications, placing higher demands on the precision and flexibility of mold technology.

[0003] First, while pin positioning offers a degree of stability, it demands extremely high machining precision. Even a slight deviation in the fixture's machining accuracy can prevent the pin from being smoothly inserted into mold cavities of different sizes, causing the die to jam and impacting production efficiency and product quality. Furthermore, pins have poor compatibility, failing to adapt to diverse production needs and increasing mold design and manufacturing costs.

[0004] Secondly, uneven distribution of suction cups is also a significant factor affecting the positioning accuracy of the faceplate. Because it's difficult to achieve a completely uniform distribution of suction cups on the fixture, unbalanced forces are generated when adsorbing the faceplate, causing it to easily lift. This lifting not only reduces positioning accuracy but can also damage the faceplate, affecting the product's appearance and performance. Utility Model Content

[0032] This utility model provides a faceplate positioning mechanism. A positioning component initially fixes the faceplate's position, ensuring it is roughly in the correct location upon initial placement. Subsequently, a suction component uses suction to further securely fix the faceplate to the fixture plate, reducing displacement caused by external forces or vibrations. Finally, a pressure component applies physical pressure through a pressure plate, ensuring the faceplate maintains extremely high positional accuracy during final processing or assembly, meeting the requirements of high-precision machining or assembly.

This dual-protection mechanism ensures consistent product quality. The highly automated positioning mechanism significantly shortens faceplate positioning time, reduces manual intervention, and improves production efficiency. Simultaneously, the high positioning accuracy reduces rework and scrap rates caused by inaccurate positioning, further enhancing overall production efficiency.

Furthermore, by replacing the fixture plate or adjusting the mechanism configuration, it can be easily applied to the positioning needs of other similar products. Example

[0033] This utility model embodiment provides a faceplate positioning mechanism, such as Figures 1 to 3 As shown, the device includes a main body 10, which includes a base plate 110 and a fixture plate 120. The fixture plate 120 is disposed on the base plate 110 and has a placement area 1210 for placing the faceplate. A positioning component 20 is disposed on the fixture plate 120. A suction component 30 is disposed on the fixture plate 120, and the suction component 30 and the positioning component 20 are respectively disposed at different positions on the fixture plate 120. A pressure component 40 is included, which includes a pressure plate 410 and a driving member 420. When the pressure plate 410 is in the first position, the pressure plate 410 is located on the placement area 1210.

[0034] like Figure 1 and Figure 2 As shown, more specifically, the fixture plate 120 and the base plate 110 are inclined.

[0035] Understandably, after the faceplate is placed in the placement area 1210 on the fixture plate 120, it is initially fixed by the positioning component 20, and then the suction component 30 clamps the faceplate. When the suction reaches the set negative pressure value, the driving component 420 drives the pressure plate 410 to descend, pressing the faceplate firmly after it reaches its position, thereby achieving a precise positioning effect for the faceplate. The pressure plate 410 has a first position and a second position. When the pressure plate 410 is in the first position, it is located on the placement area 1210. When the pressure plate 410 is in the second position, its vertical projection plane does not overlap with the placement area 1210. This can be understood as the pressure plate 410 not being located on the placement area 1210 when it is in the second position. The driving component 420 can be used to drive the pressure plate 410 to move between the first and second positions.

[0036] In this way, the relative positional relationship between the fixing point of the faceplate (such as the contact point of the positioning component 20) and the support surface (placement area 1210) changes on the inclined jig plate 120, forming a more stable support structure. This structure is beneficial for resisting external interference, reducing the shaking of the faceplate during the positioning process, and ensuring positioning accuracy. When the pressure plate 410 descends from the first position (located on the placement area 1210) to the second position (not located on the placement area 1210) under the action of the drive component 420, the inclined jig plate 120 makes the movement trajectory of the pressure plate 410 more closely match the contact surface of the faceplate. This helps to ensure that the pressure plate 410 can press the faceplate evenly and smoothly, avoiding local stress concentration or indentation, while improving the efficiency and effect of clamping. The inclined design also increases the compatibility of the jig plate 120 with faceplates of different sizes and shapes. By adjusting the inclination angle and the size of the jig plate 120, it is easier to adapt to different models of faceplates, reducing positioning difficulties caused by size differences.

[0037] like Figure 2 and Figure 3 As shown, the placement area 1210 is provided with multiple positioning components 20. More specifically, the positioning component 20 may include a positioning hole 210 and a spring pin 220 adapted to the positioning hole 210.

[0038] The placement area 1210 is equipped with multiple positioning components 20, which means that the shell can be fixed and supported from multiple directions during placement. Compared with single-point or few-point positioning, this multi-point positioning method can more effectively restrict the degree of freedom of the shell and prevent it from shaking or shifting during processing or assembly.

[0039] Positioning holes 210, matching the corresponding parts of the faceplate, are precisely machined on the placement area 1210 of the jig plate 120. The position, shape, and size of these positioning holes 210 are carefully designed to ensure that the faceplate can be accurately placed in the predetermined position. The spring pins 220 that fit into the positioning holes 210 not only have sufficient rigidity to ensure accurate positioning of the faceplate, but also have a certain degree of elasticity. When the faceplate is placed on the positioning holes 210, the spring pins 220 can automatically adjust their position to fit tightly against the corresponding parts of the faceplate. This cushioning effect avoids damage or jamming of the faceplate due to direct impact, and also reduces the alarm rate triggered by inaccurate positioning.

[0040] Understandably, the multi-point positioning combined with the buffering effect of the spring pin 220 allows the faceplate to quickly and accurately reach the predetermined position during placement, greatly improving positioning accuracy. The elastic design of the spring pin 220 not only ensures the stability of the faceplate during positioning but also absorbs external vibrations or impacts to a certain extent, preventing the faceplate from shaking or shifting. The buffering effect reduces the direct impact between the faceplate and the fixture plate 120, lowering the risk of damage to the faceplate due to improper positioning. Because the positioning is accurate and stable, alarms triggered by inaccurate positioning are reduced, improving production efficiency and equipment utilization. By adjusting the position, shape, and size of the positioning hole 210 and the spring pin 220, faceplates of different models and sizes can be easily adapted, improving the equipment's versatility and compatibility.

[0041] like Figure 3 As shown, the suction assembly 30 may include a plurality of suction cups 310. More specifically, the suction assembly 30 may be located in the center of the placement area 1210, and the positioning assembly 20 may be located around the suction assembly 30.

[0042] In this way, multiple suction cups 310 can provide a wider adsorption area, thereby enhancing the adhesion effect on the faceplate. This helps ensure that the faceplate remains stable during processing or assembly, preventing displacement or falling due to external forces. Multiple suction cups 310 can be evenly distributed in the center of the placement area 1210, making the suction force distribution on the faceplate more uniform. This helps reduce stress concentration caused by excessive local suction, protecting the faceplate surface from damage. Positioning the positioning component 20 around the suction component 30 means that the faceplate is first initially positioned by the positioning component 20, and then firmly fixed by the suction component 30. This optimized sequential layout helps ensure the approximate position of the faceplate is correct before performing fine-tuning operations, thereby improving overall positioning accuracy. The outer positioning component 20 provides additional support and restraint for the faceplate, helping to prevent rotation or tilting during suction. Meanwhile, the central suction component 30 uses strong suction to firmly adhere the faceplate to the fixture plate 120, further enhancing the stability of the faceplate.

[0043] Understandably, the clamping assembly 40 also includes a connector 430, which connects the clamping assembly 40 to the main body 10 of the mechanism. More specifically, one end of the pressure plate 410 is connected to the drive component 420, and the other end is provided with a pressure block 440. More specifically, the pressure block 440 is a urethane pressure block 440. The drive component 420 can be a cylinder, more specifically, a rotary cylinder. The clamping assembly 40 is securely connected to the main body 10 of the mechanism through the connector 430, ensuring the stability and reliability of the entire assembly during the clamping process. This design helps to reduce positioning deviations caused by vibration or external forces. One end of the pressure plate 410 is connected to the drive component 420 (such as a cylinder), and the other end is provided with a pressure block 440 (such as a urethane pressure block 440). The urethane pressure block 440 has good elasticity and cushioning performance, which can reduce the pressure impact on the surface of the face shell while clamping it, protecting it from damage. In addition, the urethane block 440 can be adapted to the shape and size of the faceplate, improving the flexibility and compatibility of positioning.

[0044] In this way, the faceplate is placed in the placement area 1210 on the jig plate 120 and positioned by the spring pin 220. Then, the suction cup 310 is vented to firmly hold the faceplate in place. When the suction reaches the set negative pressure value, the cylinder is vented, causing the pressure plate 410 to rotate onto the placement area 1210 and then descend, causing the urethane pressure block 440 to descend as well. Once in place, it presses the faceplate firmly, thus achieving a precise positioning effect. This faceplate positioning mechanism is compatible with different mold cavity faceplate positioning hole 210 sizes. It offers high positioning accuracy, ensuring processing and assembly precision. The spring pin 220 provides a buffering effect during positioning, preventing the faceplate from shaking or getting stuck, thus reducing the alarm rate.

[0045] Understandably, using a rotary cylinder as the driving component 420 not only enables the lifting and lowering of the pressure plate 410, but also precisely positions the pressure plate 410 above the placement area 1210 through rotation. This reduces the horizontal displacement error of the pressure plate 410 during descent, improving positioning accuracy and stability. The rapid response and precise control of the rotary cylinder make the pressing process faster and more efficient. After the faceplate is gripped by the suction cup 310 and reaches the set negative pressure value, the cylinder can quickly ventilate and drive the pressure plate 410 to rotate and descend into place, pressing and fixing the faceplate.

[0046] The spring pin 220 in the positioning assembly 20 provides initial positioning and cushioning during the placement of the faceplate, effectively preventing it from shaking or shifting. Simultaneously, the suction cup 310 generates negative pressure through airflow to firmly adhere the faceplate to the fixture plate 120, further enhancing positioning stability. This mechanism is compatible with different mold cavity faceplate positioning hole 210 sizes, thanks to the flexibility and adaptability of the spring pin 220 and suction cup 310 design. By adjusting the position of the spring pin 220 and the layout of the suction cup 310, positioning requirements for faceplates of different models and sizes can be easily met.

[0047] In summary, the faceplate positioning mechanism provided by this utility model embodiment combines multi-point positioning, suction component 30, and pressure component 40 in a precise design, enabling high-precision positioning of the faceplate. This helps ensure the accuracy and quality of subsequent processing and assembly. The entire positioning mechanism has a stable structure and reliable operation, maintaining a stable positioning effect under various working conditions. This reduces rework and scrap rates caused by inaccurate positioning, improving production efficiency and economic benefits. The application of buffering elements such as the urethane pressure block 440 effectively protects the faceplate surface from damage, extending its service life and reliability. The buffering effect of the spring pin 220 and the firm adsorption of the suction cup 310 together reduce alarms triggered by inaccurate positioning or faceplate shaking, improving the stability and smoothness of the production process. In addition to mobile phone faceplates, the faceplate positioning mechanism provided by this utility model embodiment can also be used for faceplates of other electronic products.

[0048] Compared with existing technologies, the faceplate positioning mechanism provided in this embodiment of the utility model initially fixes the faceplate position through a positioning component, ensuring that the faceplate is in a roughly correct position when initially placed. Subsequently, a suction component uses suction to further firmly fix the faceplate to the fixture plate, reducing displacement caused by external forces or vibrations. Finally, a pressure component applies physical pressure through a pressure plate, ensuring that the faceplate maintains extremely high positional accuracy during final processing or assembly, meeting the requirements of high-precision processing or assembly. The combined use of suction and pressure fixing methods can effectively prevent the faceplate from moving or deforming due to external forces during processing or assembly, thereby improving the stability and reliability of the entire production process. This dual-protection mechanism ensures the consistency of product quality. The highly automated positioning mechanism can significantly shorten the faceplate positioning time, reduce manual intervention, and improve production efficiency. At the same time, due to the high positioning accuracy, it reduces rework and scrap rates caused by inaccurate positioning, further improving overall production efficiency. The mechanism is flexibly designed, and the layout and parameters of the positioning component and suction component can be adjusted according to different models and sizes of faceplates, exhibiting strong versatility and adaptability. Furthermore, by replacing the fixture plate or adjusting the mechanism configuration, it can be easily applied to the positioning needs of other similar products.

[0049] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model.
