Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pressure maintaining device, in particular to a pressure maintaining device for assembling consumer electronic products. BACKGROUND

[0002] The miniaturization and high integration trend of consumer electronic products put forward higher requirements on the assembly process. As a key process, the pressure maintaining link ensures that each layer of material can be perfectly bonded under more uniform pressure through the way of temporarily loosening external force and reapplying pressure. This process helps to eliminate interlayer bubbles and voids, making the adhesion more firm, preventing interlayer separation or peeling, improving the reliability of the product, and thus enhancing the mechanical strength and electrical performance of the product. However, the existing pressure maintaining device lacks protection against repeated pressing, which can easily cause product surface step difference due to secondary pressing, affecting the appearance and product adhesion layer fatigue fracture due to repeated stress. When the external force is temporarily loosened, the assembled parts of the pressure maintaining part are prone to separation. Moreover, the traditional pressure maintaining fixture is designed as a single fixture, which is too heavy for manual handling and adjustment, has low versatility, and relies on manual setting of pressing parameters during the pressing process. It lacks real-time monitoring and closed-loop control of pressure. The shielding of the fixture structure to the key parts of the product makes it difficult to observe the assembly deviation in real time, and the assembly deviation can only be found through post-inspection, which leads to instability of the pressure maintaining quality, high production cost, and potential customer complaints or market recall.

[0021] A pressure maintaining device for consumer electronics assembly, comprising a first pressure maintaining module and a second pressure maintaining module, the first pressure maintaining module comprises a base, the base is provided with a profiling groove area and a plurality of small pressure block assemblies, the profiling groove area is placed with a to-be-pressured part, and the plurality of small pressure block assemblies are arranged in the left and right directions of the profiling groove area, the small pressure block assembly comprises an opening and closing block and a profiling small pressure block, one end of the opening and closing block is connected to the front part of the profiling groove area, the other end of the profiling small pressure block is connected to the rear part of the profiling groove area in an openable and closable manner, the profiling small pressure block is arranged on the opening and closing block, and the profiling small pressure block is closed with the opening and closing block to press the to-be-pressured part for the first pressure maintaining operation; the second pressure maintaining module comprises an assembly table 210, a supporting back plate 220 and a plurality of large pressure block modules 230, the supporting back plate 220 is connected to the assembly table 210, the large pressure block module 230 comprises a quick pressure head assembly 231, a sensor assembly 232 and a profiling large pressure block 233, the quick pressure head assembly 231 is connected to the supporting back plate 220, the sensor assembly 232 is arranged below the quick pressure head assembly 231, and the profiling large pressure block 233 is connected below the sensor assembly 232, the base of the first pressure maintaining module placed with the to-be-pressured part is assembled to the assembly table 210, the quick pressure head assembly 231 drives the profiling large pressure block 233 to press the to-be-pressured part for the second pressure maintaining operation, and the sensor assembly 232 is used for monitoring the pressure applied by the quick pressure head assembly 231 to the profiling large pressure block 233 in real time.

[0022] It needs to be explained that the invention adopts the first pressure maintaining module and the second pressure maintaining module to design the pressure maintaining device in a split body, the profiling groove area on the base of the first pressure maintaining module is designed according to the shape and size of the to-be-pressure-maintained piece, when the to-be-pressure-maintained piece needs to be pressure maintained, the opening and closing block is opened through operation, so that the to-be-pressure-maintained piece can be accurately placed in the groove area to realize preliminary positioning, then the opening and closing block is closed towards the back of the profiling groove area, and the profiling small pressing block is pressed towards the to-be-pressure-maintained piece to perform the first pressure maintaining operation on the to-be-pressure-maintained piece, so that the to-be-pressure-maintained piece is preliminarily pressed, and there is an assembly gap between the assembly parts of the to-be-pressure-maintained piece in the process of assembling consumer electronics, due to the interval arrangement of the small pressing block assembly, so that there is space to detect these gaps on the to-be-pressure-maintained piece placed in the profiling groove area, if the gaps are not within the specifications, the opening and closing block is opened to take out the to-be-pressure-maintained piece from the profiling groove area, and after adjusting the gap, the same steps are performed for the first pressure maintaining operation, and when the large pressing block module 230 temporarily releases the pressure, due to the existence of the small pressing block assembly, the separation between the assembly parts on the to-be-pressure-maintained piece caused by sudden pressure change is avoided. Then, after the to-be-pressure-maintained piece on the first pressure maintaining module is detected to meet the gap requirements, the base is assembled on the assembly table 210 of the second pressure maintaining module to ensure the accurate position of the to-be-pressure-maintained piece in the second pressure maintaining operation, the profiling large pressing block 233 is designed according to the shape and size of the corresponding position of the to-be-pressure-maintained piece in sections to ensure the uniformity and accuracy of pressing, then the fast pressing head assembly 231 is operated to drive the profiling large pressing block 233 to press towards the opening and closing block, and the second pressure maintaining operation is performed on the to-be-pressure-maintained piece, at the same time, the sensor assembly 232 monitors the pressure applied by the fast pressing head assembly 231 in real time to ensure that the pressing pressure is within the preset range, so as to avoid damage or affect the pressing effect of the to-be-pressure-maintained piece caused by excessive or insufficient pressure, and in the second pressure maintaining operation, whether the assembly gap of the to-be-pressure-maintained piece is within the design specifications can still be checked, if the assembly gap is not within the specifications, the profiling large pressing block 233 is driven away from the to-be-pressure-maintained piece by the fast pressing head assembly 231, the opening and closing block is opened, and the to-be-pressure-maintained piece is taken out from the profiling groove area, after adjusting the gap, the pressure maintaining operation is performed according to the above steps and is placed for a set time.

[0023] As described above, the present application adopts a first pressure maintaining module and a second pressure maintaining module in a split design, and adopts a profiling small pressing block to intervene in pressing in advance, so as to prevent the separation between the assembled parts of the to-be-pressure-maintained part after the pressure of the second pressure maintaining module is temporarily released during the two-pressing pressing process. The device is designed with an error-proof design. The profiling groove area and the small pressing block assembly arranged at intervals in the device structure reserve a visual observation area, which facilitates real-time visual inspection of the assembly gap of the to-be-pressure-maintained part, reduces the operation failure rate, and simultaneously realizes the visual presentation and dynamic monitoring of the pressure parameter by loading a sensor assembly 232 on the large pressing block module 230. In addition, the split design of the first pressure maintaining module and the second pressure maintaining module can support independent operation of the single device, and can also support integration into an automatic equipment for assembly in the later stage, thereby improving the operation convenience.

[0024] In an embodiment, the front part of the profiling groove area is provided with a connecting shaft 111a, the rear part of the profiling groove area is provided with a magnetic attraction piece 111b, one end of the opening and closing block is connected with the connecting shaft 111a, and the other end of the opening and closing block is magnetically connected with the magnetic attraction piece 111b. It should be noted that the connecting shaft 111a enables the opening and closing block to rotate flexibly, and the operator can easily open or close it. When the opening and closing block is closed, the magnetic attraction piece 111b can quickly and accurately attract the other end of the opening and closing block, so that the profiling small pressing block is accurately pressed against the to-be-pressure-maintained part, ensuring the accuracy of the pressure maintaining position and improving the pressure maintaining quality. The magnetic attraction force can ensure that the opening and closing block remains in a stable closed state during the pressure maintaining process, preventing the opening and closing block from loosening due to vibration or external force, avoiding displacement of the to-be-pressure-maintained part during pressure maintaining, and ensuring the consistency of the pressure maintaining effect. In this way, there is no need for complex mechanical locking structures, which reduces the complexity and cost of the device, and facilitates maintenance and repair.

[0025] In order to facilitate assembly and improve the flexibility of the device, the opening and closing block is connected with the profiling small pressing block. It can be understood that the clamping structure can quickly and stably connect the profiling small pressing block to the opening and closing block, and is convenient for quick assembly and disassembly. In production, the installation and replacement of the profiling small pressing block can be efficiently completed to adapt to the production needs of to-be-pressure-maintained parts of different specifications, accurately apply pressure to the to-be-pressure-maintained part, ensure stable pressure maintaining quality, and improve production flexibility. Figure 3 As shown in an embodiment, the opening and closing block is provided with a clamping protrusion, and the profiling small pressing block is provided with a clamping groove. The profiling small pressing block is clamped on the opening and closing block through the clamping groove and the clamping protrusion.

[0026] In an embodiment, the quick pressing head assembly 231 includes a first fixed block 231a, a pressing rod 231b, and a handle 231c. The first fixed block 231a is connected to the support back plate 220, the pressing rod 231b and the handle 231c are arranged on the first fixed block 231a, one end of the pressing rod 231b is connected to the sensor assembly 232 in a lifting manner, and the handle 231c drives the pressing rod 231b to lift or lower relative to the profiling large pressing block 233.

[0027] It should be noted that the first fixed block 231a is connected to the support back plate 220, providing a stable mounting base for the pressure rod 231b and the handle 231c, ensuring the position of the entire assembly is fixed during the pressing process, avoiding the assembly from shifting due to vibration or external force, and ensuring the accuracy of the pressing operation. The pressure rod 231b is connected to the sensor assembly 232 in a lifting manner at one end. When it is necessary to drive the profiling large pressing block 233 towards the opening and closing block quickly, the operator can flexibly adjust the pressing force and position of the pressure rod 231b by pressing or lifting the handle 231c, which can adapt to the operation of different sizes and shapes of the to-be-pressed parts. Of course, the lifting drive of the pressure rod 231b can also use other existing technical driving modes, which will not be described in detail.

[0028] In this embodiment, the sensor assembly 232 includes a second fixed block 232a, a sensor 232b and a cover plate 232c. The second fixed block 232a is connected with the first fixed block 231a, and the pressure rod 231b extends into the second fixed block 232a. A limiting cavity 232d is arranged on the bottom surface of the second fixed block 232a, which is used for limiting the upward movement of the sensor 232b. The sensor 232b is connected to one end of the pressure rod 231b extending into the second fixed block 232a. The cover plate 232c is arranged between the second fixed block 232a and the profiling large pressing block 233.

[0029] It should be noted that the second fixed block 232a is connected with the first fixed block 231a, providing a stable and reliable mounting base for the entire sensor assembly 232, ensuring that the sensor assembly 232 will not loosen or shift during the working process of the quick pressing head assembly 231 due to vibration or external force, and ensuring that the sensor 232b can always be in the accurate working position, so as to accurately obtain the pressure data. The sensor 232b is connected to one end of the pressure rod 231b extending into the second fixed block 232a, so that the pressure rod 231b can transmit the pressing pressure to the sensor 232b in real time. In a specific implementation, the high-precision sensor carried has a pressure range of 0-5000N and an accuracy of ±1% FS, ensuring that the sensor 232b can accurately monitor the pressure change during the pressing process. The limiting cavity 232d arranged on the bottom surface of the second fixed block 232a can effectively prevent the sensor 232b from being damaged due to excessive upward movement caused by excessive pressure or operation error during the pressing process. The cover plate 232c is used to uniformly transmit the pressure generated during the pressing process, making the pressure signal received by the sensor 232b more stable and accurate. Moreover, the cover plate 232c can also have a certain buffering effect, avoiding damage to the sensor 232b caused by instantaneous pressure impact, and further improving the accuracy and reliability of pressure measurement.

[0030] The modular design of the components of the sensor assembly 232 makes the components of the sensor assembly 232 relatively independent, which can be replaced and maintained individually. When the sensor 232b fails or needs to be calibrated and maintained, the sensor 232b can be operated individually by disassembling the cover plate 232c, without the need to disassemble the entire quick pressing head assembly 231, thereby shortening the maintenance time and improving the maintainability and production efficiency of the equipment.

[0031] The cover plate 232c is provided with a spring column 232e and a limiting hole 232f. The cover plate 232c is connected to the profiling large pressing block 233 through the spring column 232e. The spring column 232e extends out of the cover plate 232c towards the second fixing block 232a. The cover plate 232c is fixed to the second fixing block 232a through screwing and limiting through the limiting hole 232f.

[0032] It should be noted that the spring column 232e provides elastic buffering between the cover plate 232c and the profiling large pressing block 233 during pressing. When the quick pressing head assembly 231 drives the profiling large pressing block 233 to press down, the spring column 232e can absorb part of the impact force, so as to avoid damage to the sensor 232b or the to-be-pressed part due to instantaneous concentration of pressure, and to make the pressure transmission more stable and gentle, thereby ensuring the stability of the pressing process. When the pressing pressure exceeds the set range, the spring column 232e will be further compressed, thereby playing a role of overpressure protection, preventing damage to the sensor 232b, the profiling large pressing block 233 or the to-be-pressed part due to excessive pressure, and ensuring the safety of the equipment and products. For example, Figure 3 The spring column 232e is arranged at four corner positions of the cover plate 232c, so that the pressure buffering can be more balanced and stable. The limiting hole 232f provides a clear positioning reference for the installation of the cover plate 232c, so that the cover plate 232c can be quickly and accurately installed on the second fixing block 232a, thereby ensuring that the cover plate 232c will not be excessively displaced or deviated during the pressing process, and further ensuring that the sensor 232b can always accurately measure the pressing pressure, thereby improving the accuracy and reliability of the pressure measurement.

[0033] In some embodiments, the profiling large pressing block 233 is arranged above the opening and closing block. In order to prevent collision with the opening and closing block during the second pressing operation, the profiling large pressing block 233 is provided with a avoiding position 233a. In this way, the avoiding position 233a reserves a specific space for the opening and closing block, so as to prevent the profiling large pressing block 233 from colliding with or interfering with the opening and closing block during the pressing process, thereby ensuring that the pressing action can be smoothly performed, avoiding equipment jamming and damage. Furthermore, the profiling large pressing block 233 is provided with profiling structures on both sides of the avoiding position 233a, which are matched in shape and size with the corresponding positions of the to-be-pressed part during pressing. Therefore, the profiling large pressing block 233 can more directly and effectively act on the key parts of the to-be-pressed part during pressing, thereby reducing repeated pressing operations or poor pressing caused by pressure transmission loss, significantly improving the pressing quality, and improving the yield of products.

[0034] Understandably, consumer electronics products are diverse, and the shapes and structures of the pressure components vary. The modular design of each component in the large pressure block module 230 makes it easy to replace several contoured large pressure blocks 233. In order to quickly switch to the production of different types of products, the components can be adjusted and replaced by segmented contouring design according to their different shapes and sizes, without the need for large-scale equipment modification. This enhances the versatility and flexibility of the device and reduces production costs.

[0035] like Figure 1 A display screen 221 is mounted on the support backplate 220, and a sensor 232b is electrically connected to the display screen 221. In this way, the sensor 232b can display the pressure changes detected during the pressure holding process on the display screen 221 in real time and intuitively, realizing the visualization and dynamic monitoring of pressure parameters. Operators can precisely adjust the parameters of the pressure holding equipment during the pressure holding process based on the pressure data and other operating parameters displayed on the device, ensuring the stability and consistency of the pressure holding process. Mounting the display screen 221 on the support backplate 220 results in a more compact structure, avoiding complex wiring connections and the need for a separate mounting bracket to fix the display screen 221.

[0036] To simplify the connection between the base and the assembly table 210, L-shaped positioning blocks 211 are respectively provided on the left and right sides of the assembly table 210. The two L-shaped positioning blocks 211 are perpendicular to each other and are used to limit the connection of the base. It should be noted that the L-shaped positioning blocks on the left and right sides of the assembly table 210 form a positioning frame for the base. When the base is placed on the assembly table 210, the right-angled sides of the L-shaped positioning blocks can constrain the base from two mutually perpendicular directions, ensuring that the base is accurately positioned in the predetermined position. This greatly improves the assembly accuracy and reduces assembly errors and subsequent production problems caused by positional deviations. Understandably, when it is necessary to replace the base with a different specification, the position and size of the L-shaped positioning blocks can be flexibly adjusted to adapt to the actual needs. Furthermore, the base and the L-shaped positioning block are connected by magnetic attraction. During assembly, simply bring the base close to the limiting component, and under the action of magnetic force, the base can quickly and automatically attract the limiting component to complete the positioning connection. When maintenance, repair or replacement of the base is required, the base can be easily separated from the limiting component by overcoming the magnetic attraction.

[0037] It can be understood that if the base bottom surface is uneven, the size changes due to wear, etc., the pressure maintaining module will be positioned inaccurately on the assembly table 210, thereby affecting the uniform distribution and stability of the pressure maintaining pressure. In this regard, the first pressure maintaining module can also be provided with a wear-resistant assembly plate 120 connected to the base bottom surface. The wear-resistant assembly plate 120 can maintain the flatness and size accuracy of the base bottom surface, providing a guarantee for producing high-quality products. When the wear-resistant assembly plate 120 is worn to a certain extent due to long-term use, it can be easily replaced. Compared with directly replacing the base, the operation of replacing the wear-resistant assembly plate 120 is simpler, faster, and requires less time and cost.

[0038] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
