Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and more specifically to an assembly fixture for a car speaker grille. Background Technology

[0002] In the automotive manufacturing industry, as consumers' demands for vehicle comfort and entertainment experiences continue to rise, the configuration of in-car audio systems is receiving increasing attention. As a key component of the audio system, the installation quality of the speaker directly affects sound performance. The speaker grille, a crucial component for protecting the speaker and enhancing aesthetics, typically consists of a plastic bracket and a metal mesh. The quality of the assembly process has a vital impact on the performance and reliability of the entire speaker assembly. Traditional assembly methods often rely on manual operation or simple mechanical aids, which present numerous problems. For example, manual assembly is inefficient and prone to loosening due to improper handling, resulting in a poor fit between the plastic bracket and the metal mesh, affecting the speaker's sealing and sound stability. While some mechanical assembly equipment can improve production efficiency, key processes such as bending and flanging often employ a one-step pressing method. This makes it difficult for the plastic bracket and metal mesh to fit tightly after pressing, also leading to loosening and reducing the speaker's lifespan and performance. Furthermore, insufficient positioning accuracy during assembly can easily lead to inaccurate bending angles of the metal mesh and deformation of the plastic bracket, further affecting assembly quality. Therefore, there is an urgent need for a new type of automotive speaker grille assembly tooling that can effectively solve the problems of poor fit, loosening, low efficiency, and poor adaptability in existing assembly technologies, so as to improve assembly quality and meet the high precision, high efficiency, and high reliability requirements of the automotive manufacturing industry for speaker grille assembly. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide an assembly fixture for automotive speaker grilles. This assembly fixture pre-compresses and bends the connecting clips of the speaker bracket and the metal grille through a pre-compression module, and then presses the connecting clips into place through a clamping module, thereby improving assembly quality and assembly efficiency.

[0004] This application provides an assembly fixture for an automotive speaker grille, including a frame. The frame is provided with a mounting base, a pre-compression module, and a clamping module. The mounting base is used to mount a speaker bracket and a metal grille. The pre-compression module is used to pre-compress and bend the connecting clips of the speaker bracket and the metal grille. The clamping module is used to clamp the connecting clips of the speaker bracket and the metal grille into place. The mounting base is slidably mounted on the frame. The mounting base can slide to move the speaker bracket and the metal grille to the pre-compression module or the clamping module.

[0005] In this technical solution, the frame serves as the foundation of the entire assembly fixture, providing stable support for the mounting base, pre-compression module, and clamping module. The mounting base is equipped with a contour block adapted to the speaker's shape. The metal mesh cover and speaker bracket are sequentially installed within the contour block. The metal mesh cover has multiple connecting clips, and the speaker bracket has multiple connecting holes for the connecting clips to pass through. The metal mesh cover and speaker bracket are joined vertically in a stacked state, with the connecting clips extending through the connecting holes. By incorporating the pre-compression and clamping modules, the pre-compression module pre-bends the connecting clips, and the clamping module clamps the pre-compressed connecting clips into place. The connecting clips are assembled by bending and clamping inwards. Through the step-by-step operation of the pre-compression and clamping modules—first pre-compression bending, then clamping—the assembly of the metal mesh cover and speaker bracket is ensured. The metal mesh cover's connecting clips fit snugly against the speaker bracket, effectively solving problems such as loosening and detachment caused by one-step pressing in traditional assembly equipment. Precise control of the pre-compression and clamping modules prevents deformation of the speaker bracket due to excessive pressure during assembly, while also preventing excessive or insufficient bending of the metal mesh cover's connecting clips. This not only improves assembly quality but also extends the speaker's lifespan. Furthermore, the mounting base, which slides back and forth on the frame, drives the speaker bracket and metal mesh cover to slide synchronously. This allows for quick switching between the pre-compression and clamping modules, reducing waiting and adjustment time during assembly, minimizing manual operation, lowering operator workload, reducing assembly errors caused by improper operation, and improving assembly efficiency.

[0006] As an improvement, the pre-compression module includes a first lifting plate and a plurality of first pre-compression blocks. The first lifting plate is mounted on the frame in a height-adjustable manner, and the first pre-compression blocks are slidably mounted on the first lifting plate. The first pre-compression blocks slide to laterally abut against the connecting buckle and bend the connecting buckle. In this technical solution, a first lifting plate is installed on the frame. The first lifting plate can be vertically lifted and lowered on the frame by connecting a lifting mechanism. The lifting mechanism can be driven by a cylinder, hydraulic cylinder, or electric screw to ensure the stability and accuracy of the lifting process. The first lifting plate moves closer to or away from the mounting base by vertical lifting and lowering. Multiple first pre-compression blocks are installed on the first lifting plate. The first pre-compression blocks move synchronously with the first lifting plate. By controlling the lifting and lowering of the first lifting plate, the synchronous action of multiple first pre-compression blocks is achieved, thereby moving closer to or away from the connecting buckle of the speaker bracket and the metal mesh cover. The first pre-compression blocks are set to slide back and forth on the first lifting plate. When the first lifting plate descends to the position, the first pre-compression blocks slide to abut laterally against the connecting buckle and pre-compress and bend the connecting buckle inward, improving the pre-compression quality and pre-compression efficiency.

[0007] As an improvement, the first lifting plate is provided with a first slide rail adapted to the first pre-compression block. The first pre-compression block passes through the first slide rail for lateral abutment against the connecting buckle. A first driving mechanism is installed on the first lifting plate, and the first driving mechanism is connected to the first pre-compression block to drive the first pre-compression block to slide. In this technical solution, the design of the first slide rail ensures that the first pre-compression block always maintains an accurate lateral abutment direction during the sliding process, avoiding inaccurate pre-compression angle due to sliding deviation. The first slide rail allows the first pre-compression block to pass through, and the first pre-compression block passing through the first slide rail can laterally abut against the connecting buckle, avoiding interference of the first lifting plate with the sliding of the first pre-compression block. The overall structure is more compact, which is conducive to reducing the overall size of the machine. The first driving mechanism is installed on the first lifting plate and connected to the first pre-compression block to drive the sliding of the first pre-compression block, ensuring the smoothness and accuracy of the sliding process and improving the pre-compression efficiency.

[0008] As an improvement, the bottom of the first pre-compression block is provided with a notch adapted to the connecting buckle, and the first pre-compression block avoids the connecting buckle through the notch. In this technical solution, the bottom of the first pre-compression block is provided with a notch adapted to the connecting buckle, ensuring that the first pre-compression block can accurately avoid the main body of the connecting buckle during the lifting and lowering process. The bottom of the first pre-compression block can be laterally attached to the main body of the connecting buckle to perform the pre-compression operation. The first pre-compression block laterally abuts against the bent part of the connecting buckle through the notch and pre-compresses and bends it inward, ensuring that the pre-pressure is evenly distributed on the bent part of the connecting buckle, avoiding deformation or damage of the connecting buckle due to excessive local pressure. The design is more ingenious and the pre-compression efficiency is higher.

[0009] As an improvement, a first connecting plate is slidably mounted on the first lifting plate, and multiple second pre-compression blocks are mounted on the first connecting plate. The first connecting plate drives the second pre-compression blocks to slide synchronously, and the second pre-compression blocks slide to laterally abut against the connecting buckle and bend the connecting buckle. In this technical solution, multiple second pre-compression blocks are mounted on the first connecting plate. By sliding the first connecting plate, the multiple second pre-compression blocks slide synchronously, ensuring that the multiple second pre-compression blocks move in a consistent manner during the pre-compression process. This makes the sliding stroke and speed of each pre-compression block consistent, improving the uniformity and consistency of pre-compression, and meeting the needs of multi-variety, small-batch production in automobile manufacturing.

[0010] As an improvement, the first connecting plate is provided with a first slider, and the first lifting plate is provided with a second slide rail. The first slider and the second slide rail are slidably connected. A second driving mechanism is installed on the first lifting plate, and the second driving mechanism drives the first connecting plate to slide. In this technical solution, the sliding connection between the first slider and the second slide rail allows the first connecting plate to slide back and forth relative to the first lifting plate, ensuring the stability and guidance of the sliding process of the first connecting plate, avoiding vibration and offset during the sliding process, and improving the accuracy and consistency of the pre-compression action. The second pre-compression block always maintains an accurate lateral contact direction during the sliding process, improving the uniformity of the pre-compression effect. The second driving mechanism can adopt a cylinder, hydraulic cylinder, or electric screw drive method to ensure the smoothness and accuracy of the sliding process.

[0011] As an improvement, the first lifting plate is equipped with multiple first positioning posts. The first lifting plate drives the first positioning posts to rise and fall synchronously. The first positioning posts press or loosen against the speaker bracket and metal mesh cover on the mounting base by rising and falling. In this technical solution, multiple first positioning posts are installed on the first lifting plate. During the lifting process of the first lifting plate, the first positioning posts can rise and fall synchronously, ensuring the consistency of the actions of multiple positioning posts, improving the stability and reliability of the assembly process, ensuring that the clamping force is evenly distributed on the speaker bracket and metal mesh cover, avoiding insufficient or excessive clamping in some areas, and improving the uniformity and consistency of the assembly. The first lifting plate achieves vertical lifting by connecting to a lifting mechanism. The lifting mechanism can be driven by cylinders, hydraulic cylinders, or electric screws, ensuring the smoothness and accuracy of the lifting process and improving the overall quality of the assembly.

[0012] As an improvement, the clamping module includes a second lifting plate and a second positioning column. The second lifting plate is movably mounted on the frame, and the second positioning column is mounted on the second lifting plate to move synchronously with it. The second positioning column, through its movement, clamps or loosens the speaker bracket and metal mesh cover on the mounting base. In this technical solution, the second lifting plate is mounted on the frame via a lifting mechanism, enabling precise vertical lifting movement. The lifting mechanism can employ a cylinder, hydraulic cylinder, or electric screw drive to ensure the smoothness and precision of the lifting process. The second positioning column is mounted on the second lifting plate, and by controlling the lifting of the second lifting plate, the synchronous movement of multiple second positioning columns is achieved, ensuring consistent lifting stroke and speed for each positioning column, improving the uniformity and consistency of the assembly. The design of the second positioning column is for precise positioning and clamping of the speaker bracket and metal mesh cover on the mounting base, improving the stability and reliability of the assembly.

[0013] As an improvement, a second connecting plate is movably mounted on the second lifting plate, and multiple first clamping columns are mounted on the second connecting plate. The second connecting plate is used to drive the first clamping columns to move up and down synchronously. The second pre-compression block is used to tighten or loosen the connecting clips by moving up and down. In this technical solution, the second connecting plate is movably mounted on the second lifting plate, and the second connecting plate can be further raised and lowered relative to the second lifting plate. Multiple first clamping columns are mounted on the second connecting plate. The first clamping columns are used to precisely clamp the connecting clips. The first clamping columns tighten or loosen the connecting clips by moving up and down. By raising and lowering the second connecting plate, the multiple first clamping columns move up and down synchronously, ensuring that the multiple first clamping columns move in a consistent manner during the clamping process, thus improving the uniformity and consistency of the clamping.

[0014] As an improvement, a third drive mechanism is installed on the second lifting plate. This third drive mechanism is connected to the second connecting plate to drive the second connecting plate to rise and fall. The second connecting plate has a through hole for the second positioning post to pass through. In this technical solution, the third drive mechanism is used to drive the second connecting plate to rise and fall. The third drive mechanism can use a cylinder, hydraulic cylinder, or electric screw, etc., to ensure the smoothness and accuracy of the lifting process. The through hole on the second connecting plate allows the second positioning post to pass through and abut against the speaker bracket and metal mesh cover. The synchronous rising and falling movement of the second positioning post by the second lifting plate is not interfered with by the second connecting plate, resulting in a more compact overall structure and helping to reduce the overall size of the machine.

[0026] like Figures 1 to 6 As shown, this application discloses an assembly fixture for a vehicle speaker grille, including a frame 1. The frame 1 is provided with a mounting base 2, a pre-compression module 3, and a clamping module 4. The mounting base 2 is used to install a speaker bracket 5 and a metal grille 6. The pre-compression module 3 is used to pre-compress and bend the connecting buckles 61 of the speaker bracket 5 and the metal grille 6. The clamping module 4 is used to clamp the connecting buckles 61 of the speaker bracket 5 and the metal grille 6 into place. The frame 1 serves as the foundation of the entire assembly fixture, providing stable support for the mounting base 2, the pre-compression module 3, and the clamping module 4. The mounting base 2 is provided with a contour block adapted to the shape of the speaker. The metal grille 6 and the speaker bracket 5 are sequentially installed in the contour block. The metal grille 6 is provided with multiple connecting buckles 61. The speaker bracket 5 is provided with multiple connecting holes 51 for the connecting buckles 61 to pass through. The metal grille 6 and the speaker bracket 5 are joined together vertically to form a stacked state. The connecting buckles 61 extend through the connecting holes 51.

[0027] By setting up a pre-compression module 3 and a clamping module 4, the pre-compression module 3 can pre-compress and bend the connecting buckle 61, and the clamping module 4 can clamp the pre-compressed connecting buckle 61 into place. The connecting buckle 61 achieves the assembly and forming of the metal mesh cover 6 and the speaker bracket 5 by bending and clamping inward. Through the step-by-step operation of the pre-compression module 3 and the clamping module 4, the pre-compression and bending are performed first, and then the clamping is performed in place, ensuring that the connecting buckle 61 of the metal mesh cover 6 and the speaker bracket 5 fit tightly. This effectively solves the problems of loose fit and detachment caused by one-step pressing in traditional assembly equipment. The precise control of the pre-compression module 3 and the clamping module 4 avoids the speaker bracket 5 from deforming due to excessive pressure during the assembly process, and at the same time prevents the connecting buckle 61 of the metal mesh cover 6 from being over-bent or under-bent. This not only improves the assembly quality, but also extends the service life of the speaker.

[0028] like Figure 1 and Figure 4 As shown, the mounting base 2 is slidably mounted on the frame 1. The mounting base 2 moves the speaker bracket 5 and the metal mesh cover 6 to the pre-compression module 3 or the clamping module 4 by sliding. The mounting base 2 is set to slide back and forth on the frame 1. The mounting base 2 drives the speaker bracket 5 and the metal mesh cover 6 to slide synchronously, so that the speaker bracket 5 and the metal mesh cover 6 can quickly switch to the pre-compression module 3 or the clamping module 4, reducing the waiting time and adjustment time in the assembly process, reducing manual operation, reducing the labor intensity of operators, and reducing assembly errors caused by improper operation, thereby improving assembly efficiency.

[0029] More specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the pre-compression module 3 includes a first lifting plate 31 and multiple first pre-compression blocks 32. The first lifting plate 31 is slidably mounted on the frame 1, and the first pre-compression blocks 32 are slidably mounted on the first lifting plate 31. The first pre-compression blocks 32 slide to laterally abut against the connecting buckle 61 and bend the connecting buckle 61. The first lifting plate 31 is mounted on the frame 1 and can be vertically lifted and lowered on the frame 1 by connecting a lifting mechanism. The lifting mechanism can be driven by a cylinder, hydraulic cylinder, or electric screw to ensure the stability and accuracy of the lifting process. The first lifting plate 31 is vertically lifted and lowered to abut against the connecting buckle 61. Multiple first pre-compression blocks 32 are installed on the first lifting plate 31, either near or far from the mounting base 2. The first pre-compression blocks 32 rise and fall synchronously with the first lifting plate 31. By controlling the rise and fall of the first lifting plate 31, the synchronous action of the multiple first pre-compression blocks 32 is achieved, thereby allowing them to move closer to or further away from the connecting buckle 61 of the speaker bracket 5 and the metal mesh cover 6. The first pre-compression blocks 32 are designed to slide back and forth on the first lifting plate 31. When the first lifting plate 31 is lowered to the position, the first pre-compression blocks 32 slide to abut against the connecting buckle 61 laterally, and pre-compress and bend the connecting buckle 61 inward, thereby improving the pre-compression quality and pre-compression efficiency.

[0030] More specifically, such as Figure 5As shown, the first lifting plate 31 is provided with a first slide rail 311 adapted to the first pre-compression block 32. The first pre-compression block 32 passes through the first slide rail 311 to laterally abut against the connecting buckle 61. The first lifting plate 31 is equipped with a first drive mechanism 33, which is connected to the first pre-compression block 32 to drive the first pre-compression block 32 to slide. The design of the first slide rail 311 ensures that the first pre-compression block 32 always maintains an accurate lateral abutment direction during the sliding process, avoiding inaccurate pre-compression angle due to sliding deviation. The first slide rail 311 allows the first pre-compression block 32 to pass through, and the first pre-compression block 32 can laterally abut against the connecting buckle 61 by passing through the first slide rail 311, avoiding the first lifting plate 31 from interfering with the sliding of the first pre-compression block 32. The overall structure is more compact, which is conducive to reducing the size of the whole machine. The first drive mechanism 33 is installed on the first lifting plate 31 and connected to the first pre-compression block 32 to drive the sliding of the first pre-compression block 32, ensuring the smoothness and accuracy of the sliding process and improving the pre-compression efficiency.

[0031] More specifically, such as Figure 5 As shown, the bottom of the first pre-compression block 32 is provided with a notch 321 that matches the connecting buckle 61. The first pre-compression block 32 avoids the connecting buckle 61 through the notch 321, ensuring that the first pre-compression block 32 can accurately avoid the main body of the connecting buckle 61 during the lifting and lowering process. The bottom of the first pre-compression block 32 can be laterally attached to the main body of the connecting buckle 61 to perform the pre-compression operation. The first pre-compression block 32 abuts against the bent part of the connecting buckle 61 laterally through the notch 321 and pre-compresses and bends it inward, ensuring that the pre-pressure is evenly distributed on the bent part of the connecting buckle 61, avoiding deformation or damage to the connecting buckle 61 due to excessive local pressure. The design is more ingenious and the pre-compression efficiency is higher.

[0032] More specifically, such as Figure 3 and Figure 5 As shown, a first connecting plate 34 is slidably mounted on the first lifting plate 31, and a plurality of second pre-compression blocks 35 are mounted on the first connecting plate 34. The first connecting plate 34 is used to drive the second pre-compression blocks 35 to slide synchronously. The second pre-compression blocks 35 slide to laterally abut against the connecting buckle 61 and bend the connecting buckle 61. The first connecting plate 34 is mounted with a plurality of second pre-compression blocks 35. By sliding the first connecting plate 34, the plurality of second pre-compression blocks 35 are driven to slide synchronously, ensuring that the plurality of second pre-compression blocks 35 move in a consistent manner during the pre-compression process, so that the sliding stroke and speed of each pre-compression block are consistent, thereby improving the uniformity and consistency of pre-compression and meeting the needs of multi-variety and small-batch production in automobile manufacturing.

[0033] More specifically, such as Figure 3 and Figure 5As shown, the first connecting plate 34 is provided with a first slider 341, and the first lifting plate 31 is provided with a second slide rail 312. The first slider 341 and the second slide rail 312 are slidably connected. The first lifting plate 31 is equipped with a second drive mechanism 36. The second drive mechanism 36 drives the first connecting plate 34 to slide. Through the slidable connection between the first slider 341 and the second slide rail 312, the first connecting plate 34 can slide back and forth relative to the first lifting plate 31, ensuring the stability and guidance of the sliding process of the first connecting plate 34, avoiding vibration and deviation during the sliding process, and improving the accuracy and consistency of the pre-compression action. The second pre-compression block 35 always maintains an accurate lateral contact direction during the sliding process, improving the uniformity of the pre-compression effect. The second drive mechanism 36 can be driven by a cylinder, hydraulic cylinder, or electric screw, etc., to ensure the smoothness and accuracy of the sliding process.

[0034] More specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, a plurality of first positioning posts 37 are installed on the first lifting plate 31. The first lifting plate 31 is used to drive the first positioning posts 37 to rise and fall synchronously. The first positioning posts 37 press or loosen the speaker bracket 5 and metal mesh cover 6 on the mounting base 2 by rising and falling. The installation of multiple first positioning posts 37 on the first lifting plate 31 ensures that the first positioning posts 37 can rise and fall synchronously during the lifting process of the first lifting plate 31, thereby improving the stability and reliability of the assembly process and ensuring that the pressing force is evenly distributed on the speaker bracket 5 and metal mesh cover 6, avoiding insufficient or excessive local pressing, and improving the uniformity and consistency of the assembly. The first lifting plate 31 achieves vertical lifting by connecting to a lifting mechanism. The lifting mechanism can be driven by a cylinder, hydraulic cylinder or electric screw, etc., to ensure the smoothness and accuracy of the lifting process and improve the overall quality of the assembly.

[0035] More specifically, such as Figure 1 , Figure 4 and Figure 6As shown, the clamping module 4 includes a second lifting plate 41 and a second positioning column 42. The second lifting plate 41 is movably mounted on the frame 1, and the second positioning column 42 is mounted on the second lifting plate 41 to move synchronously with it. The second positioning column 42 clamps or loosens the speaker bracket 5 and metal mesh cover 6 on the mounting base 2 by moving up and down. The second lifting plate 41 is mounted on the frame 1 by connecting a lifting mechanism, which enables precise vertical lifting movement. The lifting mechanism can be driven by a cylinder, hydraulic cylinder, or electric screw, etc., to ensure the smoothness and precision of the lifting process. The second positioning column 42 is mounted on the second lifting plate 41. By controlling the lifting of the second lifting plate 41, the synchronous action of multiple second positioning columns 42 is achieved, ensuring that the lifting stroke and speed of each positioning column are consistent, improving the uniformity and consistency of the assembly. The design of the second positioning column 42 is used to accurately position and clamp the speaker bracket 5 and metal mesh cover 6 on the mounting base 2, improving the stability and reliability of the assembly.

[0036] More specifically, such as Figure 1 , Figure 4 and Figure 6 As shown, a second connecting plate 43 is movably mounted on the second lifting plate 41. Multiple first pressing columns 44 are mounted on the second connecting plate 43. The second connecting plate 43 drives the first pressing columns 44 to move up and down synchronously. The second pre-pressing block 35 is used to press or release the connecting buckle 61 by moving up and down. The second connecting plate 43 is movably mounted on the second lifting plate 41 and can be further raised and lowered relative to the second lifting plate 41. Multiple first pressing columns 44 are mounted on the second connecting plate 43. The first pressing columns 44 are used to precisely press the connecting buckle 61. The first pressing columns 44 press or release the connecting buckle 61 by moving up and down. By raising and lowering the second connecting plate 43, multiple first pressing columns 44 move up and down synchronously, ensuring that the multiple first pressing columns 44 move in unison during the pressing process, thus improving the uniformity and consistency of the pressing.

[0037] More specifically, such as Figure 1 , Figure 4 and Figure 6As shown, a third drive mechanism 45 is installed on the second lifting plate 41. The third drive mechanism 45 is connected to the second connecting plate 43 to drive the second connecting plate 43 to rise and fall. The second connecting plate 43 is provided with a through hole 431 for the second positioning column 42 to pass through. The third drive mechanism 45 is used to drive the second connecting plate 43 to rise and fall. The third drive mechanism 45 can be driven by a cylinder, hydraulic cylinder or electric screw, etc., to ensure the smoothness and accuracy of the lifting process.
