Description

Technical Field

[0001] This invention relates to the field of headphone manufacturing equipment technology, specifically to an automatic alignment and bonding device for speakers and headphone housings. Background Technology

[0002] In the manufacturing process of consumer electronics, headphones, as a high-precision acoustic device, rely heavily on assembly processes that significantly impact final sound quality and product durability. The precise and secure attachment of the speaker unit to the headphone housing is a core step in the assembly process. The quality of this step directly affects the headphone's airtightness, the stability of the acoustic cavity, and the overall structural strength. Therefore, achieving efficient and high-precision automated attachment of the speaker to the headphone housing has become a critical technical challenge in the headphone manufacturing industry.

[0003] Currently, the industry commonly uses semi-automated workstations to complete this task. These devices typically include a programmable three-axis dispensing robotic arm and a worktable for placing the headphone housing. However, in practical applications, these existing technologies still have significant shortcomings in terms of structural design and process flow. These devices generally rely on custom-made, fixed-size fixtures tailored to specific product models to position the headphone housing. This single clamping structure results in extremely poor versatility. Whenever different specifications of headphones need to be produced, a significant amount of time must be spent on downtime, disassembling, and replacing the entire set of fixtures, severely restricting the flexibility and efficiency of the production line and increasing additional mold costs.

[0004] Furthermore, the workflow of such equipment is structurally fragmented, with the dispensing station and the subsequent pressing station typically being independent physical units. After dispensing, the operator must manually place the speaker onto the glue-coated housing, then remove this pre-positioned assembly from the fixture and transfer it to a separate press for pressing. During this manual transfer, the speaker, held together solely by the surface tension of the glue, is highly susceptible to displacement due to vibration or contact, resulting in significantly reduced bonding accuracy and compromised product consistency.

[0005] More importantly, the entire process relies too heavily on manual labor and lacks an automated structure for pre-processing incoming materials. Existing technical solutions generally lack online cleaning units for electrostatic elimination and dust removal on speaker surfaces. The direct manual handling and open operating environment not only easily introduce external dust and impurities into the product, affecting the bonding effect, but also result in low overall production efficiency. Product quality is highly dependent on the operator's skill level and condition, failing to meet the requirements of modern precision electronic manufacturing for high efficiency, high cleanliness, and high stability. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an automatic alignment and bonding device for speaker and headphone housings. It solves the problems of poor versatility and cumbersome production line switching caused by the use of fixed clamps in existing equipment; low alignment accuracy and poor product consistency caused by the separation of dispensing and pressing stations and reliance on manual transfer; and low overall automation level, lack of online cleaning function which easily introduces pollution and makes it difficult to improve production efficiency.

An arc-shaped clamping block is installed on the top of the connecting plate, and a drive rod is rotatably connected to the bottom of the connecting plate. The rotating plate has an arc-shaped groove inside that corresponds to the straight sliding groove. The arc-shaped clamping block is slidably connected to the straight sliding groove through the connecting plate and slides in cooperation with the arc-shaped groove through the drive rod.

[0008] Preferably, the fastening adjustment assembly further includes a second motor disposed below the rotating plate, the rotating shaft of the second motor being fixedly connected to the bottom center of the rotating plate; the bottom of the top plate is provided with a mounting groove for mounting the rotating plate to rotate, and two side limiting grooves are also provided on both sides of the linear slide groove.

[0009] Preferably, the arc-shaped clamping block has a downward pressing block slidably connected vertically inside; the connecting plate has multiple slots for the downward pressing block to be inserted into; the arc-shaped clamping block also has a horizontally slidably connected insert block inside, the end of the insert block has an inclined surface, and the top of the downward pressing block has a pressure-bearing inclined surface that fits against the inclined surface of the insert block.

[0010] Preferably, side limiting plates are fixedly connected to both outer sides of the pressing block, and the side limiting plates are slidably connected inside the arc-shaped clamping block; a first tension spring is fixedly connected to the top of the side limiting plate, and a second tension spring is fixedly connected to the internal slot of the insertion block.

[0011] Preferably, the pressing assembly includes a guide rail, on which a dispensing head is mounted, and two high-definition cameras are also fixedly mounted on the guide rail, the two high-definition cameras being symmetrically arranged on both sides of the dispensing head; the guide rail also integrates an outer frame, a first motor installed inside the outer frame, and a threaded rod, the first motor driving a lower pressure plate located at the bottom of the threaded rod to move vertically through the threaded rod.

[0012] Preferably, the cleaning transport assembly includes a transport seat, with multiple fixing ears on both sides of the bottom of the transport seat, multiple ion fans installed inside the transport seat, and multiple air supply ducts on both sides of the top of the transport seat.

[0013] Preferably, the cleaning transport assembly further includes a guide slide, the interior of which is provided with multiple insulated brush rollers and an arc-shaped ventilated base plate, and a removable cover plate is installed on the rear side of the guide slide, with a waste pipe connected to its bottom.

[0014] Preferably, two protective covers are also installed on the rear side of the processing box, and robotic arms are installed inside both of them.

[0015] Preferably, a bottom box is installed at the bottom of the processing box; a load-bearing plate is installed on one side of the processing box, and a vibrating feeding tray and a control box are installed on the top of the load-bearing plate; two real-time display screens are installed on the side wall of the processing box.

[0016] Preferably, the other side of the processing box is provided with a discharge port, and a curing box is provided inside the processing box for curing the bonded speaker and headphone housings.

[0017] This invention provides an automatic alignment and bonding device for a speaker and an earphone shell. It has the following advantages: 1. This invention achieves efficient compatibility and stable clamping of headphone shells of different specifications through a uniquely structured fastening and adjustment component. This component utilizes a motor-driven rotating plate, and through the precise cooperation of arc-shaped grooves and linear slides, converts the rotational motion into the synchronous linear motion of multiple arc-shaped clamping blocks, thereby achieving automatic and rapid clamping and release. More importantly, through the linkage locking structure of the insert block, the pressing block, and the multiple slots, operators can easily adjust the initial position of the clamping blocks to adapt to workpieces of different sizes, greatly enhancing the equipment's flexible production capacity and versatility, and avoiding the production interruptions and additional costs caused by replacing the entire set of fixtures when changing products, as is common in existing technologies.

[0018] 2. This invention highly integrates dispensing, visual positioning, and pressing functions into a single pressing assembly, significantly improving the accuracy and reliability of alignment and bonding. This pressing assembly integrates a high-definition camera, dispensing head, and lower pressure plate onto a single moving guide rail. During dispensing, the camera provides real-time visual guidance for the dispensing path; after dispensing, the robotic arm places the speaker in position; subsequently, the lower pressure plate immediately applies pressure for bonding under the same positional reference. This "integrated design at the same workstation" eliminates secondary positioning errors caused by workpiece transfer between different workstations in existing technologies, ensuring high precision throughout the entire process from visual alignment to final pressing, thereby significantly improving product yield and quality consistency.

[0019] 3. This invention establishes a fully automated, closed-loop production process from material loading and cleaning to finished product curing, effectively ensuring product cleanliness and improving production efficiency. By adding a cleaning and transport component with dual cleaning functions of an ion fan and brush rollers, the impact of static electricity and dust on bonding quality is eliminated at the source. Simultaneously, using robotic arms to replace manual labor for speaker placement and finished product transfer not only avoids contamination and operational errors caused by human contact but also seamlessly connects cleaning, clamping, dispensing, bonding, and curing processes, forming a continuous and efficient automated assembly line operation. The entire core process is completed within a closed processing chamber, further isolating external environmental interference, ultimately achieving a comprehensive improvement in production efficiency, product cleanliness, and quality stability.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 2 This invention provides an automatic alignment and bonding device for speaker and headphone housings. Its overall structure is built on a stable base box 1, and the core operations are all completed within a sealed processing box 2 installed on top of the base box 1 to ensure the cleanliness of the production process. On one side of the processing box 2, a load-bearing plate 3 is provided, on which a vibrating feeding tray 4 for orderly supplying speaker units and a control box 5 serving as the equipment control center are installed side-by-side. To facilitate real-time monitoring of the complex operation process within the box by operators, two real-time display screens 6 are also installed on the side wall of the processing box 2.

[0024] Reference Appendix Figure 3 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 and attached Figure 10To achieve efficient compatibility and stable clamping of headphone shells of different specifications, this invention features a uniquely structured fastening and adjusting assembly 12 at the center of the processing box 2. The core of this assembly is a precision linkage mechanism consisting of an upper top plate 1201 and a lower rotating plate 1202. When the headphone shell needs to be clamped, a second motor 1203 located below the rotating plate 1202 is activated. Its rotating shaft is fixedly connected to the bottom center of the rotating plate 1202, driving the rotating plate 1202 to rotate smoothly within the mounting groove 1205 at the bottom of the top plate 1201. As the rotating plate 1202 rotates, the three arc-shaped grooves 1204 inside it drive the slidingly engaged drive rod 1208 to generate a combined radial and tangential motion. Since the other end of each drive rod 1208 is rotatably connected to the bottom of a connecting plate 1209, and each connecting plate 1209 is constrained within three linear grooves 1206 inside the top plate 1201 to perform purely linear motion, the rotational motion of the rotating plate 1202 is precisely converted into synchronous centripetal linear motion of the three connecting plates 1209; the arc-shaped clamping block 1210 mounted on the top of each connecting plate 1209 moves toward the center, thereby firmly clamping the headphone shell.

[0025] To ensure smooth movement, two guide grooves 1207 are provided on both sides of the linear slide 1206, which connect to the limiting blocks fixed on both sides of the bottom of the arc-shaped clamping block 1210. More importantly, to accommodate workpieces of different sizes, this assembly also features a sophisticated manual adjustment and locking device. The operator can pull the insert block 1215, and after overcoming the tension of the second tension spring 1216, the inclined surface at its end will disengage from the pressure-bearing inclined surface 1217 on the top of the pressing block 1212. At this time, under the action of the first tension spring 1214 connected to the top of the side limiting plate 1213, the pressing block 1212 springs upward, disengaging from the slot 1211 inside the connecting plate 1209. At this point, the arc-shaped clamping block 1210 can be freely moved to the desired position. After the insert block 1215 is released, it resets under the action of spring force and presses the pressing block 1212 back into the new slot 1211, thus locking the position. The side limiting plate 1213 is slidably connected inside the arc-shaped clamping block 1210, ensuring the stability of the movement of the pressing block 1212.

[0026] Reference Appendix Figure 3 - Appendix Figure 4To significantly improve the accuracy and reliability of alignment and bonding, this invention highly integrates dispensing, visual positioning, and pressing functions into a single pressing assembly 10. This pressing assembly 10 is mounted on a guide rail 1001 that can move freely horizontally within the processing box 2. Once the earphone shell is clamped into position by the fastening and adjusting assembly 12, the guide rail 1001 drives the entire pressing assembly 10 to move directly above the workpiece. At this time, two high-definition cameras 1002, symmetrically positioned on either side of the dispensing head 1003, capture real-time images of the earphone shell and transmit the data to the control box 5. After calculation, the dispensing path is precisely planned, guiding the dispensing head 1003 to complete accurate glue application.

[0027] After the dispensing process is completed, the robotic arm 9, installed inside the protective cover 8 at the rear of the processing box 2, precisely places a cleaned speaker onto the earphone shell coated with adhesive. Immediately afterwards, without moving the workpiece, the pressing mechanism of the clamping assembly 10 is activated. The first motor 1005, installed inside the outer frame 1004, drives the threaded rod 1006 to rotate, thereby causing the pressure plate 1007 located at the bottom of the threaded rod 1006 to descend steadily and vertically, applying uniform and precise pressure to the newly bonded speaker and earphone shell, ensuring a tight bond. This "integrated" structural design, which completes visual positioning, dispensing, and pressing sequentially under the same position reference, fundamentally eliminates positioning errors caused by workpiece transfer between different workstations, ensuring extremely high alignment accuracy and quality consistency of the final product.

[0028] Reference Appendix Figure 5 - Appendix Figure 6 To effectively ensure product cleanliness and comprehensively improve production efficiency, this invention constructs a fully automated, closed-loop production process from material feeding and cleaning to finished product curing. First, the loudspeaker is systematically fed into the cleaning transport assembly 11 by a vibrating feeding tray 4. After entering the transport seat 1101, multiple ion fans 1103 installed inside blow out ionized air through multiple air ducts 1104 at the top to neutralize the static electricity generated on the loudspeaker surface due to friction, preventing dust adsorption. Subsequently, the loudspeaker continues to advance along the guide slide 1105, where multiple insulated brush rollers 1106 inside the slide remove any micro-dust particles that may be attached to its surface. This dust falls into the internal cavity of the slide through openings in the arc-shaped ventilated base plate 1109 and is collected and processed through the waste pipe 1107 at the bottom. The entire cleaning transport assembly 11 is securely mounted inside the processing box 2 by multiple fixing ears 1102 at the bottom, and a removable cover plate 1108 is installed on its rear side for easy maintenance. After cleaning, robotic arm 9 removes the cleaned speaker for subsequent bonding processes.

[0029] After the pressing component 10 completes the pressing, another robotic arm 9 removes the pre-formed product from the fastening and adjusting component 12 and places it into the curing chamber 13 inside the processing chamber 2 for heat curing to optimize the adhesive performance. The fully cured product is then discharged from the equipment through the discharge port 7 on the other side of the processing chamber 2. The entire process is seamless and fully automated within the sealed processing chamber 2, minimizing human intervention and environmental pollution.

[0030] Working principle: A processing box 2 is installed on the top of the base box 1. The processing box 2 serves as the main processing area, where subsequent speaker cleaning, headphone shell glue application, and alignment bonding are all completed. A load-bearing plate 3 is installed on one side of the processing box 2. A vibrating feeding tray 4 and a control box 5 are installed on the top two sides of the load-bearing plate 3, respectively. The vibrating feeding tray 4 is used to orderly input multiple speaker units into the cleaning and transport assembly 11 inside the processing box 2, while the control box 5 is used for subsequent overall control. Two real-time display screens 6 are installed on the side wall of the processing box 2, the top of the vibrating feeding tray 4, and the control box 5, to monitor the specific processing status inside the processing box 2 in real time. On the other side of the processing box 2, an outlet 7 is provided for easy transport of the molded headphones. A cleaning and transport assembly 11 is installed at the discharge point of the vibrating feeder 4. The loudspeaker first enters the top of the transport seat 1101 for transmission. Multiple fixing ears 1102 are provided on both sides of the bottom of the transport seat 1101, and multiple bolts are used to firmly fix the transport seat 1101 to the inside of the processing box 2. Inside the transport seat 1101, multiple ion fans 1103 are installed. Through multiple air ducts 1104 provided on both sides of the top of the transport seat 1101, they blow air containing positive and negative ions towards the loudspeaker during transport. The purpose is to remove the dust attracted by the outside environment due to static electricity generated by the loudspeaker during transportation. A guide is also provided at the discharge point at the top of the transport seat 1101. After static electricity removal, the speaker can slide into the next step through the arc-shaped ventilated base plate 1109 set at the top of the guide slide 1105. On both sides of the inside of the guide slide 1105 and above the ventilated base plate 1109, multiple insulating brush rollers 1106 are evenly distributed to remove residual dust carried on the speaker. The brush rollers are connected to the internal cavity of the guide slide 1105 through the waste pipe 1107. The rear side of the guide slide 1105 is equipped with a removable cover plate 1108 to keep it sealed. This allows the dust that has been swept down to enter the interior of the guide slide 1105 through multiple ventilation holes in the ventilated base plate 1109 and finally be extracted from the processing box 2. Two protective covers 8 are installed on the rear side of the processing box 2, and robotic arms 9 are installed inside both of them. The purpose is to send the speaker after dust removal into the step of pressing it with the headphone shell and transporting the finished product, reducing manual intervention and the entry of external dust, and improving the efficiency of operation. A fastening and adjusting assembly 12 is installed in the center of the processing box 2. This assembly effectively clamps the earphone shell placed by the worker, facilitating subsequent gluing and pressing. The fastening and adjusting assembly 12 primarily employs a rotary clamping mechanism. Its main body includes a top plate 1201 and a rotating plate 1202, with the rotating plate 1202 rotatably connected to the mounting groove 1205 at the bottom of the top plate 1201. A second motor 1203 is installed at the bottom of the rotating plate 1202, its shaft driving the rotating plate 1202 to rotate. Three arc-shaped grooves 1204 are evenly spaced inside the rotating plate 1202, and correspondingly, three straight sliding grooves 1206 are also provided inside the top plate 1201. The arc-shaped grooves 1204 are designed with... A drive rod 1208 is provided, which can slide as the rotating plate 1202 rotates, thereby driving the connecting plate 1209 rotatably connected to its top. The connecting plate 1209 is slidably connected inside the linear slide groove 1206. Through the combination of the above-mentioned multiple parts, the rotational motion of the rotating plate 1202 is effectively converted into the linear motion of the arc-shaped clamping block 1210 installed on the top of the connecting plate 1209. The three arc-shaped clamping blocks 1210 move towards each other to clamp the earphone shell placed in the center of the top plate 1201. Two side limiting grooves 1207 are also provided on both sides of the straight slide groove 1206, which correspond to the two limiting blocks on both sides of the bottom of the arc-shaped clamping block 1210. Inside the arc-shaped clamping block 1210, a downward pressing block 1212 is vertically slidably connected. Correspondingly, multiple slots 1211 are provided inside the connecting plate 1209. Side limiting plates 1213 are fixedly connected to both sides of the external side of the downward pressing block 1212. They slide inside the downward pressing block 1212 to prevent the downward pressing block 1212 from falling out of the arc-shaped clamping block 1210. Inside the arc-shaped clamping block 1210, an insert block 1215 is also horizontally slidably connected. Its end has an inclined surface that fits against the top pressure inclined surface 1217 of the downward pressing block 1212. When the insert block 1215 is pulled inward by the second tension spring 1216, it will push the downward pressing block 1212 downward, so that it is finally locked inside the slot 1211. To accommodate different sized headphone shells, the staff can pull the plug 1215. The pressure block 1212, which loses its downward pressure, will retract back into the arc-shaped clamp 1210 under the action of the first tension spring 1214 on the top of the two side limit plates 1213 on both sides. After adjusting to the appropriate position, the staff will release the plug 1215 and finally push the pressure block 1212 into the appropriate slot 1211. After the complete earphone shell is fixed, the pressure-fixing assembly 10 located on the top wall of the processing box 2 starts to work. It includes a set of guide rails 1001 that can move on a plane, which can drive the dispensing head 1003 to move to the place where glue needs to be applied on the top of the earphone shell. Two high-definition cameras 1002 are set on both sides of the dispensing head 1003, which are connected to two real-time display screens 6 on the side wall of the processing box 2 and controlled by the control box 5. A miniature cylinder for easy up and down movement and a glue tank for storing glue are also installed on one side of the dispensing head 1003. An outer frame 1004 is also installed at the bottom of the guide rail 1001. Through the internal first motor 1005, threaded rod 1006 and lower pressure plate 1007, after the robot arm 9 places the cleaned speaker in the correct position of the earphone shell with glue applied, the lower pressure plate 1007 applies pressure to the position where the speaker and the earphone shell meet, so as to ensure that the glue plays a better role. After complete alignment and bonding, another robotic arm 9 can remove the contacted and fixed earphone shell and place it inside the curing box 13 to cure the glue bonding. After the fixation is completed, the earphone is transported out of the processing box 2 through the discharge port 7.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
