Description

Technical Field

[0001] This utility model relates to the field of automated equipment for speaker production, and in particular discloses a dispensing device for speaker production lines. Background Technology

[0002] In current speaker production line dispensing operations, traditional equipment has many limitations: most adopt a single-station design, relying on manual switching of work processes, resulting in low space utilization and poor production continuity, and inefficiency due to delays caused by manual operation; dispensing components are mostly single-drive structures with limited dispensing range, making it difficult for single-gun operation to cover multiple points, and lacking lateral glue replenishment function, often resulting in glue leakage and insufficient dispensing accuracy, affecting speaker bonding quality; substrate transfer and finished product transfer rely heavily on manual labor, which not only has high labor costs but also easily causes product damage due to operational errors; the conveying device lacks a precise positioning structure, making it easy for products to deviate during transmission, leading to poor connection with subsequent processes; each equipment component is mostly independently controlled, with poor coordination, making it difficult to adapt to the needs of large-scale automated production, and the equipment wears out quickly with a high risk of downtime, failing to meet the requirements of high efficiency and precision in speaker production. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a dispensing device for a speaker production line.

[0004] To achieve the above objectives, this utility model provides a dispensing device for a speaker production line, comprising a frame, a dispensing station rotatably mounted on the frame, a drive device for driving the dispensing station to rotate, a dispensing assembly, a transfer assembly, and a control unit mounted on the frame. The dispensing station is used to support external speaker bases, the transfer assembly is used to place external speaker substrates onto the speaker bases on the dispensing station, and the control unit is electrically connected to the drive device, the dispensing assembly, and the transfer assembly.

[0005] This structure organically integrates the core components of the dispensing device. The frame provides stable support for the entire equipment, ensuring structural stability during operation and preventing dispensing accuracy from being affected by equipment shaking. The rotating dispensing station, in conjunction with the drive unit, enables multi-station cyclical operation, significantly improving space utilization and production continuity while reducing station changeover waiting time. The transfer assembly automatically completes the assembly and docking of the speaker substrate and base, replacing manual operation, reducing labor costs, and avoiding positional deviations caused by manual placement. The control unit centrally controls all components, precisely coordinating the drive unit's rotation speed, the dispensing volume of the dispensing assembly, and the timing of the transfer assembly's actions. This ensures smooth transitions between stages, significantly improving the overall accuracy and production efficiency of dispensing and assembly, meeting the needs of large-scale, automated speaker production lines.

[0006] Furthermore, the dispensing assembly includes a support frame reciprocating on the frame, a first dispensing driver that drives the support frame to reciprocate, a dispensing gun reciprocating on the support frame, and a second dispensing driver that drives the dispensing gun to reciprocate.

[0007] This dispensing assembly structure, through its dual-layer reciprocating motion design, greatly expands the range and flexibility of the dispensing gun. The support frame, driven by the first dispensing driver, reciprocates as a whole, allowing the dispensing gun to adjust its position within a large space to accommodate the dispensing area requirements of different speaker base sizes. The dispensing gun, driven by the second dispensing driver, reciprocates independently, precisely controlling the dispensing path and distance in localized areas, such as for precise positioning of dispensing dots at different locations on the speaker base. The dual-layer drive structure works in tandem to achieve multi-dimensional adjustment of the dispensing position, effectively avoiding the limited range or insufficient precision of a single drive method. This ensures the dispensing gun accurately aligns with the dispensing position on the speaker base, improving dispensing accuracy, and also flexibly adapts to the production of different speaker models, enhancing the equipment's versatility and adaptability.

[0008] Furthermore, the number of dispensing guns is set to multiple, and the multiple dispensing guns are arranged circumferentially around the drive shaft of the second dispensing driver.

[0009] The design of multiple dispensing guns arranged circumferentially around the drive shaft significantly improves the coverage and efficiency of a single dispensing operation. When dealing with multiple dispensing points on the speaker base, there is no need to frequently adjust the position of a single dispensing gun. Multiple dispensing guns can simultaneously dispense at different points, greatly shortening the time required for a single dispensing operation. This is particularly suitable for production scenarios with a large number of dispensing points on the speaker base, effectively increasing the dispensing output per unit time. The circumferential arrangement ensures a uniform and reasonable distribution of the dispensing guns, avoiding mutual interference during the dispensing process and ensuring that each dispensing gun operates independently and stably. At the same time, simultaneous dispensing by multiple guns reduces the frequency of dispensing gun movement, reduces mechanical wear and tear on the equipment, extends the service life of the dispensing guns, and allows other dispensing guns to continue working even if some dispensing guns malfunction, reducing the risk of equipment downtime and ensuring the stable operation of the production line.

[0010] Furthermore, the dispensing assembly is provided with a lateral compensation glue assembly, which has a lateral glue gun reciprocatingly mounted on the dispensing assembly and a lateral driver for driving the lateral glue gun to reciprocate.

[0011] The addition of the lateral compensating adhesive assembly effectively solves the problems of missed or insufficient adhesive application that may occur in traditional dispensing processes. It provides a targeted dispensing solution, especially for areas such as the sides or edges of the speaker base that are difficult to cover precisely with conventional dispensing guns. Driven by a lateral driver, the lateral adhesive gun can reciprocate, flexibly adjusting the position and angle of the lateral dispensing. This ensures that the bonding area on the side of the speaker base is also evenly and sufficiently covered with adhesive, improving the adhesion, sealing, and firmness between the speaker base and the substrate. It prevents loosening or poor sealing after speaker assembly due to insufficient lateral adhesive, which could affect speaker sound quality and lifespan. Furthermore, the lateral compensating adhesive assembly works in conjunction with the main dispensing assembly to form comprehensive dispensing coverage. This eliminates the need for additional independent dispensing equipment, simplifying the overall equipment structure and reducing investment costs. Simultaneously, the control unit coordinates its movement with the main dispensing assembly, ensuring a continuous dispensing process and not affecting overall production efficiency.

[0012] Furthermore, the driving device includes a drive motor and a cam divider disposed at the output end of the drive motor. The frame is provided with a support platform, and the number of dispensing stations is set to multiple, which are arranged around the central axis of the support platform.

[0013] The drive unit employs a structure combining a drive motor and a cam divider, offering advantages such as high transmission precision and stable operation. The drive motor provides stable power, while the cam divider converts the continuous rotational motion of the motor into intermittent, precise rotation of the dispensing stations. This ensures that each dispensing station is accurately positioned when stopped, preventing station wobbling or offset, and providing a stable working platform for subsequent dispensing, transfer, and other operations, significantly improving the operational precision of each process. Multiple dispensing stations are arranged around the central axis of the support platform, forming a circular operating layout. This allows for synchronous cyclical operation of multiple stations. For example, while one station is dispensing, other stations can simultaneously perform operations such as placing speaker bases, transferring speaker substrates, or picking up and placing finished products. These parallel processes significantly shorten the production cycle and improve the overall utilization rate of the equipment. This layout also facilitates loading and unloading operations by operators or automated equipment around the perimeter of the ring, optimizing the workflow and further enhancing the automation level and production efficiency of the production line.

[0014] Furthermore, the dispensing station includes a disc, a positioning flange disposed on the edge of the disc, and a bearing surface disposed on the disc for supporting the speaker base, wherein the bearing surface is arc-shaped to the disc.

[0015] The disc structure of the dispensing station, coupled with edge positioning flanges, effectively positions and limits the speaker base. The positioning flanges prevent lateral displacement of the speaker base during rotation or operation at the dispensing station, ensuring the speaker base remains in the preset working position. This guarantees precise dispensing of the components and prevents dispensing position deviations caused by base displacement, thus avoiding impacts on product quality. The curved bearing surface design matches the shape of the speaker base, increasing the contact area between the bearing surface and the speaker base, making the speaker base more stable and reducing wobbling during operation. The curved structure also prevents pressure or scratch damage to the speaker base surface, protecting the product's appearance. Furthermore, this structure is simple to manufacture, has low production costs, and facilitates subsequent cleaning and maintenance. It is less prone to structural damage during long-term use, ensuring stable operation of the dispensing station and improving the overall reliability and service life of the equipment.

[0016] Furthermore, the transplanting assembly is a rotary transplanting structure, which includes a rotary cylinder mounted on a frame, a support arm mounted on the rotary cylinder, and a gripping assembly mounted at one end of the support arm.

[0017] The rotary transfer structure uses a rotary cylinder as its power source, featuring rapid response and precise positioning. It quickly rotates the support arm, significantly reducing the switching time between the material picking and unloading positions and improving transfer efficiency. The support arm has a simple and rigid structure, stably supporting the clamping component and the clamped horn substrate, preventing the horn substrate from shifting due to deformation during rotation. The clamping component firmly grips the horn substrate, ensuring it won't fall off or wobble during transfer, guaranteeing stability and safety. Compared to linear transfer structures, the rotary transfer structure has a more compact movement trajectory and occupies less space, making it particularly suitable for scenarios with limited internal space in dispensing equipment. It effectively optimizes the internal layout of the equipment and reduces the overall footprint. Furthermore, the structure is easy to operate; the rotation angle and speed of the rotary cylinder can be precisely adjusted via the control unit to adapt to the transfer needs of different horn substrate sizes, enhancing the versatility and flexibility of the transfer component.

[0018] Furthermore, the frame is provided with a robotic arm unit, and the output end of the robotic arm unit is provided with a gripping component. The gripping component includes a support frame located at the output end of the robotic arm unit, gripper fingers that open and close on the support frame, and a gripping cylinder that drives the gripper fingers to open and close.

[0019] The addition of a robotic arm unit to the frame significantly expands the automation range and functionality of the equipment. This robotic arm unit possesses multi-degree-of-freedom motion capabilities, allowing for flexible adjustment of the gripping component's position and angle. It can adapt to the gripping needs of speaker products in different positions and of different specifications. For example, it can precisely grip finished speaker products after dispensing and assembly, transferring them to subsequent conveying devices or storage areas, replacing manual material handling, reducing labor intensity, and avoiding product damage or contamination that may occur during manual handling. The gripping components' claws open and close under the drive of gripping cylinders, with controllable gripping force. The gripping force can be adjusted according to the speaker product's material and structure, ensuring a firm grip without causing deformation or damage due to excessive force. The support frame provides stable support for the claws and gripping cylinders, ensuring the overall structural stability of the gripping component. This prevents loosening or wobbling during robotic arm movement, further improving the precision and stability of the gripping operation and ensuring the smooth operation of subsequent processes on the production line.

[0020] Furthermore, the gripper fingers are provided with grooves, the bottom size of which is smaller than the opening size, and the groove has a frustum-shaped opening structure from the bottom to the opening.

[0021] The frustum-shaped opening groove on the gripper fingers provides excellent positioning and clamping adaptability. The bottom dimension of the groove is smaller than the opening dimension, forming a structure that is wider on the outside and narrower on the inside. When gripping speaker products, this guides the product precisely into the bottom of the groove, achieving automatic centering and preventing product displacement during gripping, ensuring accurate gripping position. The frustum-shaped opening structure allows the groove to adapt to speaker products of different sizes and specifications. As long as the product size is within the groove's compatibility range, stable clamping can be achieved through the guiding action of the conical surface, significantly enhancing the versatility of the gripper fingers. This eliminates the need for frequent replacement of gripper fingers to adapt to different product models, reducing equipment adjustment time and improving production efficiency. Simultaneously, the frustum-shaped structure also increases the contact area between the gripper fingers and the product, resulting in a more even distribution of clamping force, reducing product damage caused by excessive local pressure, protecting the product's appearance and structural integrity, and improving product yield.

[0022] Furthermore, the dispensing device for the speaker production line also includes a conveying device, which is equipped with a positioning component. The positioning component has a sensor and a V-shaped positioning part disposed on the conveying device.

[0023] The addition of a conveyor system enables automated transfer of speaker products between the dispensing unit and other production line equipment, replacing manual handling, reducing labor costs, and preventing product damage during manual handling, thus ensuring the safety and integrity of the products during transport. The positioning component's sensors can detect the position of the speaker products on the conveyor system in real time. When the product reaches the preset position, the sensor feeds a signal back to the control unit, controlling the conveyor system to start and stop precisely, ensuring the product can be operated at the designated position for subsequent operations, such as robotic arm grasping or manual assistance, improving the accuracy of the transfer process. The V-shaped positioning section has an automatic centering function, guiding and positioning the product during transport. Regardless of whether the product's initial placement position is off, it can be automatically corrected to the center position when passing through the V-shaped positioning section, ensuring the product maintains the correct posture and position throughout transport. This provides precise positioning assurance for subsequent operations with the dispensing unit (such as loading the speaker base to the dispensing station), preventing product transport position deviations from affecting the overall production process, and further improving the automation and efficiency of the production line.

[0024] The beneficial effects of this invention are as follows: The frame ensures stability; the rotating dispensing station, in conjunction with the drive motor and cam divider, achieves precise intermittent cycling across multiple stations, improving space utilization and continuity; the dispensing assembly features a dual-layer drive, multi-gun circumferential arrangement, and lateral adhesive compensation, expanding the dispensing range, improving efficiency and accuracy, and preventing adhesive leakage; the transfer assembly's rotating transfer mechanism, in conjunction with the robotic arm's gripping assembly, quickly and accurately completes substrate transfer and finished product transfer, reducing labor costs and damage risks; the gripper's finger cone groove enhances gripping adaptability and stability; the conveying device, equipped with sensors and a V-shaped positioning part, achieves automatic transmission and precise alignment, ensuring smooth connection. The entire system is centrally controlled by the control unit, with each component working in tandem, improving dispensing assembly accuracy, production efficiency, and equipment versatility, meeting the needs of large-scale automation, while reducing losses and downtime risks, and extending equipment lifespan.

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] Please see Figures 1 to 6 As shown, this utility model discloses a dispensing device for a speaker production line, comprising a frame 1, a dispensing station 2 rotatably mounted on the frame 1, a drive device 3 for driving the dispensing station 2 to rotate, a dispensing assembly 4 mounted on the frame 1, a transfer assembly 5, and a control unit 6. The dispensing station 2 is used to support external speaker bases, and the transfer assembly 5 is used to place external speaker substrates onto the speaker bases on the dispensing station 2. The control unit 6 is electrically connected to the drive device 3, the dispensing assembly 4, and the transfer assembly 5.

[0034] In practice, the speaker base is first placed on the dispensing station 2 by manual or automated feeding mechanism. Then, the control unit 6 issues a command to start the drive device 3, which rotates the dispensing station 2 to the preset dispensing position below the dispensing assembly 4. At this time, the control unit 6 controls the dispensing assembly 4 to start, and performs dispensing operation on the speaker base according to the preset dispensing parameters (such as dispensing volume and dispensing path). After dispensing is completed, the control unit 6 drives the drive device 3 again, causing the dispensing station 2 to rotate to the working position corresponding to the transfer assembly 5. Under the control of the control unit 6, the transfer assembly 5 moves to pick up the speaker base from the speaker base storage area and accurately place it on the dispensing station 2 where the dispensing has been completed, realizing the initial assembly of the speaker base and the base.

[0035] After assembly, the control unit 6 drives the drive device 3 to rotate the dispensing station 2 to the next process position (such as the finished product pick-up and drop position). Throughout the process, the control unit 6 receives the operation feedback signals of each component in real time and coordinates the rotation speed of the drive device 3, the dispensing timing of the dispensing component 4 and the action rhythm of the transfer component 5 according to the preset program to ensure that each link is connected in an orderly manner and realize the automated operation of speaker dispensing and assembly, which is suitable for continuous operation needs in mass production scenarios.

[0036] Specifically, the dispensing assembly 4 includes a support frame 7 reciprocatingly mounted on the frame 1, a first dispensing driver 8 that drives the support frame 7 to reciprocate, a dispensing gun 9 reciprocatingly mounted on the support frame 7, and a second dispensing driver 11 that drives the dispensing gun 9 to reciprocate.

[0037] In practice, after the dispensing station 2 moves the speaker base to the dispensing area, the control unit 6 sends a signal to the first dispensing driver 8. The first dispensing driver 8 (which can be a linear cylinder or a servo motor) starts and drives the support frame 7 to reciprocate along the preset guide rail on the frame 1, adjusting the overall position of the dispensing gun 9 in the horizontal direction so that the dispensing gun 9 is roughly aligned with the dispensing area of ​​the speaker base. Subsequently, the control unit 6 sends a command to the second dispensing driver 11 (which can also be a high-precision servo motor or a miniature cylinder). The second dispensing driver 11 drives the dispensing gun 9 to reciprocate along the guide rail on the support frame 7, making fine adjustments to the position and ensuring that the dispensing nozzle of the dispensing gun 9 is accurately aligned with each dispensing point on the speaker base.

[0038] During the dispensing process, the control unit 6 synchronously controls the movement speed and stroke of the first and second dispensing drivers 11 according to the specifications of the speaker base. For example, for a larger speaker base, the first dispensing driver 8 drives the support frame 7 to move slowly, expanding the dispensing coverage area, while the second dispensing driver 11 adjusts the local position of the dispensing gun 9. For a smaller base, the stroke of the first dispensing driver 8 can be shortened, and precise dot positioning can be achieved through the second dispensing driver 11. At the same time, the dispensing action of the dispensing gun 9 is synchronized with the movement of the drivers. When the driver drives the dispensing gun 9 to the designated dot, the control unit 6 controls the dispensing gun 9 to dispense glue. After completing the dispensing at one dot, the driver drives the dispensing gun 9 to move to the next dot until the dispensing operation of the entire speaker base is completed.

[0039] Specifically, the number of dispensing guns 9 is set to multiple, and the multiple dispensing guns 9 are arranged circumferentially around the drive shaft of the second dispensing driver 11.

[0040] In the specific implementation process, the number of glue guns 9 (e.g., 4, 6, etc.) is determined according to the number and distribution of glue points on the speaker base, and they are fixed circumferentially around the drive shaft of the second glue dispensing driver 11 (e.g., the output shaft of a rotary motor) at uniform angles (e.g., intervals of 90°, 60°). When the second glue dispensing driver 11 is started, its drive shaft drives multiple glue guns 9 to rotate synchronously, and at the same time, in conjunction with the reciprocating motion function of the second glue dispensing driver 11, the distance between the glue guns 9 and the speaker base is adjusted.

[0041] For example, when there are four evenly distributed glue dispensing points on the speaker base, four circumferentially arranged glue guns 9 are selected. The control unit 6 controls the rotation of the drive shaft of the second glue dispensing driver 11, so that each glue gun 9 is aligned with a glue dispensing point. Then, the second glue dispensing driver 11 drives the glue gun 9 to move towards the speaker base. After reaching a preset distance, the control unit 6 controls all glue guns 9 to dispense glue synchronously, completing the glue dispensing operation of the four points in one go. This eliminates the need for each glue gun 9 to move the points one by one, significantly shortening the glue dispensing time. If the points on the speaker base are unevenly distributed, the control unit 6 can adjust the position of each glue gun 9 by adjusting the rotation angle and reciprocating stroke of the second glue dispensing driver 11, so that each glue gun 9 can still accurately align with the corresponding point, achieving flexible adaptation.

[0042] Meanwhile, during the dispensing process, the control unit 6 monitors the dispensing volume of each dispensing gun 9 in real time. If any dispensing gun 9 experiences an abnormal dispensing, an alarm can be issued in a timely manner and the operation can be suspended, facilitating maintenance by staff and ensuring the consistency of dispensing quality.

[0043] Specifically, the dispensing assembly 4 is provided with a lateral compensation glue assembly 12, which has a lateral glue gun 13 reciprocatingly mounted on the dispensing assembly 4 and a lateral driver 14 for driving the lateral glue gun 13 to reciprocate.

[0044] In practice, after the glue application on the front of the speaker base is completed, the control unit 6 identifies the model parameters of the speaker base and determines whether lateral glue application is required (e.g., some speaker bases have adhesive grooves on the side, requiring additional glue application). If glue application is required, the control unit 6 sends a command to the lateral driver 14 (usually a micro servo motor or a small linear cylinder). The lateral driver 14 drives the lateral glue gun 13 to reciprocate along the preset lateral guide rail on the glue application assembly 4, adjusting the horizontal position and height of the lateral glue gun 13 so that it is aligned with the glue application area on the side of the speaker base.

[0045] For example, when there is an annular glue filling groove on the side of the speaker base, the lateral driver 14 first drives the lateral glue gun 13 to move to the starting position of the glue filling groove. Then, the control unit 6 controls the lateral glue gun 13 to dispense glue at a preset dispensing speed. At the same time, the lateral driver 14 drives the lateral glue gun 13 to make uniform reciprocating motion along the trajectory of the glue filling groove to ensure that the glue is evenly filled into the glue filling groove. If the glue filling area consists of multiple discrete lateral points, the lateral driver 14 drives the lateral glue gun 13 to move to each point one by one, stays for a preset time, dispenses glue, and then moves to the next point after completing the glue filling of a single point.

[0046] During the glue application process, the control unit 6 monitors the distance between the side glue gun 13 and the speaker base in real time using sensors to prevent collisions between the side glue gun 13 and the base. Simultaneously, it regulates the glue dispensing amount to prevent excessive or insufficient glue from affecting the bonding effect. After glue application is complete, the side actuator 14 drives the side glue gun 13 to return to its initial position, awaiting the next glue application command. This allows it to work in conjunction with the main dispensing assembly 4 to achieve comprehensive glue coverage of the speaker base.

[0047] Specifically, the driving device 3 includes a drive motor 15 and a cam divider 16 disposed at the output end of the drive motor 15. The frame 1 is provided with a support platform 17, and the number of dispensing stations 2 is set to multiple, with the multiple dispensing stations 2 arranged around the central axis of the support platform 17.

[0048] In practice, the number of dispensing stations 2 is first determined based on the production line's capacity requirements (e.g., 6 or 8 stations), and they are fixed at equal angular intervals around the central axis of the support platform 17 at the edge of the platform 17 (e.g., at intervals of 60° or 45°). After the equipment is started, the control unit 6 sends a start signal to the drive motor 15, and the drive motor 15 (selected as a stepper motor or servo motor) starts running, transmitting power from its output to the cam divider 16. The cam divider 16, according to the preset dividing angle (matching the number of dispensing stations 2, e.g., 6 stations correspond to a dividing angle of 60°), converts the continuous rotation of the drive motor 15 into the intermittent rotation of the support platform 17. That is, after the support platform 17 drives all dispensing stations 2 to rotate a preset angle, it automatically stops for a period of time, and continues to rotate after the corresponding process of that station is completed.

[0049] For example, when the first dispensing station 2 rotates to the base loading position, the support platform 17 stops, and the loading mechanism places the horn base at this station. Then, the drive motor 15, in conjunction with the cam divider 16, rotates the support platform 17 60°, bringing the first station to the dispensing position while the second station reaches the loading position. At this time, the dispensing component 4 dispenses glue to the base at the first station, and the loading mechanism loads the base at the second station; the two processes run in parallel. After dispensing and loading are completed, the support platform 17 rotates another 60°, bringing the first station to the position of the transfer component 5 for substrate assembly, the second station to the dispensing position, and the third station to the loading position, and so on, achieving multi-station cyclical operation with each process carried out simultaneously, significantly improving production efficiency. The high-precision characteristics of the cam divider 16 ensure that the dispensing station 2 is accurately positioned each time the support platform 17 stops, with the error controlled within a small range (e.g., ±0.05mm), guaranteeing the operational accuracy of subsequent processes.

[0050] Specifically, the dispensing station 2 includes a disc 18, a positioning flange 19 disposed on the edge of the disc 18, and a bearing surface 21 disposed on the disc 18 for supporting the speaker base. The bearing surface 21 is arc-shaped to the disc 18.

[0051] In the specific implementation process, when loading the speaker base, the loading mechanism (manual or automated equipment) places the speaker base on the arc-shaped bearing surface 21 of the disc 18. The curvature of the arc-shaped bearing surface 21 matches the curvature of the bottom of the speaker base, allowing the speaker base to naturally conform to the bearing surface 21 after placement, increasing the contact area and preventing the base from wobbling due to single-point support or insufficient contact area. At the same time, the positioning flange 19 on the edge of the disc 18 surrounds the outside of the bearing surface 21. When the speaker base is placed, if there is a slight deviation, the positioning flange 19 will prevent the base from moving further outward, limiting it within the preset range of the bearing surface 21, thus achieving initial positioning.

[0052] During the rotation of the dispensing station 2 with the support platform 17, even if the equipment experiences slight vibrations, the contact support of the arc-shaped support surface 21 and the limiting effect of the positioning flange 19 ensure that the speaker base remains centered on the support surface 21 and does not slide laterally or flip over. When the dispensing assembly 4 dispenses adhesive onto the base, the stable support prevents dispensing position deviations caused by base displacement. When the transfer assembly 5 places the speaker base, the precise positioning of the base ensures that the base can be accurately placed at the preset docking position on the base, reducing assembly deviations.

[0053] Furthermore, after subsequent processes are completed, when the material handling mechanism picks up the finished speaker, the arc-shaped bearing surface 21 and the positioning flange 19 will not obstruct the picking action. The material handling mechanism can smoothly remove the finished product from the bearing surface 21. At the same time, the arc-shaped structure is also easy to clean. If glue drips onto the bearing surface 21 during the glue application process, it can be cleaned by simple wiping, avoiding glue accumulation that may affect the subsequent placement of the base.

[0054] Specifically, the transplanting component 5 is a rotary transplanting structure, which includes a rotary cylinder 22 mounted on the frame 1, a support arm 23 mounted on the rotary cylinder 22, and a clamping component 24 mounted on one end of the support arm 23.

[0055] In practice, after the glue dispensing station 2 moves the glued speaker base to the transplanting area, the control unit 6 sends a command to the rotary cylinder 22. The rotary cylinder 22 (a vane-type rotary cylinder 22 with a preset rotation angle, such as 90° or 180°) starts, causing the support arm 23 at its output end to rotate around the central axis of the rotary cylinder 22. The support arm 23 rotates to the corresponding position on the speaker base storage rack at the preset angle. At this time, the control unit 6 sends a gripping signal to the gripping component 24. The gripping component 24 (such as a pneumatic finger) opens its grippers under air pressure, aligns them with the speaker base on the storage rack, and then closes its grippers to firmly hold the speaker base (the gripping force is adjusted by air pressure to avoid damaging the base).

[0056] After clamping is complete, the control unit 6 controls the rotary cylinder 22 to rotate in the opposite direction, driving the support arm 23 and the clamping assembly 24 back to above the dispensing station 2. At this time, the support arm 23 adjusts the position of the clamping assembly 24 through the fine-tuning function of the rotary cylinder 22, so that the speaker base is precisely aligned with the speaker base on the dispensing station 2. After the position is aligned, the control unit 6 controls the grippers of the clamping assembly 24 to open, placing the speaker base stably on the speaker base, completing the base transfer. After the transfer is completed, the rotary cylinder 22 drives the support arm 23 to rotate back to the initial position (such as next to the storage rack), waiting for the next transfer command.

[0057] Throughout the process, the rapid response of the rotary cylinder 22 (adjustable rotation speed, such as 0.5s / 90°) shortens the transplanting time. The rigid structure of the bearing arm 23 ensures that the clamping component 24 will not shake during rotation. The precise clamping of the clamping component 24 ensures that the speaker base will not fall off or be damaged during transplanting. It is suitable for close-range, high-frequency base transplanting scenarios and matches the rhythm of multi-station cyclic operations.

[0058] Specifically, the frame 1 is provided with a robotic arm unit 25, and the output end of the robotic arm unit 25 is provided with a gripping component 26. The gripping component 26 includes a support frame 27 provided at the output end of the robotic arm unit 25, a gripper finger 28 that is opened and closed on the support frame 27, and a gripping cylinder 29 that drives the gripper finger 28 to open and close.

[0059] In practice, after the speaker base and the substrate are assembled at the dispensing station 2, the control unit 6 drives the drive device 3 to rotate the dispensing station 2 to the working range of the robotic arm unit 25. At this time, the control unit 6 sends a gripping command to the robotic arm unit 25, and the robotic arm unit 25 (selecting a multi-degree-of-freedom industrial robotic arm, such as a 4-axis or 6-axis robotic arm) drives the gripping component 26 at its output end to move above the assembled speaker product according to the preset motion trajectory.

[0060] During movement, the robotic arm unit 25 adjusts its posture in real time using its own position sensor to ensure that the gripper fingers 28 of the gripping component 26 can accurately align with the sides or preset gripping positions of the finished speaker. After reaching the designated position, the control unit 6 sends a signal to the gripping cylinder 29, which then vents air to drive the gripper fingers 28 to perform relative opening and closing movements along the guide rails on the support frame 27. When the gripper fingers 28 close, they clamp the finished speaker from both sides. The clamping force is adjusted by the air pressure of the gripping cylinder 29 (e.g., for finished speakers made of plastic, the air pressure is adjusted to 0.3-0.5 MPa to avoid injury).

[0061] After clamping, the robotic arm unit 25 moves the gripping component 26 and the finished horn along a preset path, transferring the finished product to the conveying device 32 (for the next process) or to the finished product storage box (for collection). Upon reaching the target position, the gripping cylinder 29 exhausts air, the gripper fingers 28 open, releasing the finished horn. The robotic arm unit 25 then moves the gripping component 26 back to its initial waiting position, ready for the next gripping operation. The multi-degree-of-freedom nature of the robotic arm unit 25 allows it to adapt to the gripping needs of horn products in different positions and of different specifications. Even if there is a slight deviation in the position of the finished product at the dispensing station 2, the robotic arm can compensate through real-time adjustments to ensure a high success rate. Simultaneously, automated gripping replaces manual material handling, reducing human intervention and improving production efficiency and operational safety.

[0062] Specifically, the gripper finger 28 is provided with a groove 31, the bottom size of the groove 31 is smaller than the size of the opening, and the groove 31 has a frustum-shaped opening structure from the bottom to the opening.

[0063] During the gripping operation, when the robotic arm unit 25 moves the gripper fingers 28 close to the finished speaker, the frustum-shaped groove 31 of the gripper fingers 28 first contacts the edge of the finished speaker. Because the opening of the groove 31 is larger than its bottom, forming a frustum shape that is wider at the outside and narrower at the inside, even if there is a slight deviation in the initial alignment between the gripper fingers 28 and the finished speaker (such as a 1-2mm left or right offset), the edge of the finished speaker can slide along the conical surface of the groove 31 into the bottom of the groove 31. During the closing process of the gripping cylinder 29 driving the gripper fingers 28, the conical surface guides the finished speaker, gradually correcting it to the center position at the bottom of the groove 31, achieving automatic centering and positioning. This ensures that the finished speaker is in the same gripping position of the gripper fingers 28 each time it is gripped, preventing the finished product from tilting or falling off during transfer due to gripping position deviations.

[0064] For example, for cylindrical horn products, the frustum-shaped grooves 31 of the gripper fingers 28 can wrap around the cylindrical surface from both sides, with the bottom of the grooves 31 fitting snugly against the cylindrical surface, increasing gripping stability. For square horn products, the conical surface of the grooves 31 can guide the edges and corners of the product into the bottom, achieving precise gripping. Simultaneously, the structural design of the frustum-shaped grooves 31 can also adapt to horn products of different sizes. For instance, when the diameter or width of the horn product is within a certain range (e.g., a difference of 3-5mm), it can slide into the bottom guided by the conical surface of the grooves 31 without needing to replace the gripper fingers 28, enhancing the versatility of the gripping component 26. When releasing the product, the gripper fingers 28 open, and the opening structure of the frustum-shaped grooves 31 does not obstruct the product, allowing it to smoothly detach from the gripper fingers 28, preventing the product from getting stuck in the grooves 31 and ensuring smooth gripping and release processes.

[0065] Specifically, the dispensing device for the speaker production line also includes a conveying device 32, on which a positioning component 33 is provided. The positioning component 33 has a sensor 34 and a V-shaped positioning part 35 disposed on the conveying device 32.

[0066] In practice, the conveyor belt of the conveying device 32 (which can be a belt conveyor or a roller conveyor) runs at a preset speed (e.g., 0.5-1 m / s) to transport the horn base to the loading position or to transport the assembled horn product to the next process. When transporting the horn base, the base is placed on the conveyor belt by upstream equipment (e.g., base processing equipment) and moves forward with the conveyor belt. When the base moves to the front of the V-shaped positioning part 35 of the positioning component 33, the sensor 34 (e.g., a photoelectric sensor or proximity switch) on the conveyor belt first detects the arrival of the base. The sensor 34 transmits the detection signal to the control unit 6. The control unit 6 adjusts the operating state of the conveying device 32 according to the signal, and can appropriately reduce the conveyor belt speed (e.g., from 1 m / s to 0.2 m / s) so that the base slowly enters the V-shaped positioning part 35.

[0067] The V-shaped positioning section 35 consists of two symmetrical V-shaped baffles. After the base enters the V-shaped area, its two side edges contact the inclined surfaces of the V-shaped baffles. Under the continuous conveying force of the conveyor belt, the base slides along the inclined surfaces and gradually moves towards the apex (center position) of the V-shaped positioning section 35, eventually being corrected to the central axis position of the conveyor belt, achieving precise positioning. After positioning is completed, the sensor 34 sends a signal to the control unit 6 again. The control unit 6 controls the conveyor device 32 to stop running (or maintain low-speed operation). At this time, the loading mechanism (such as a robotic arm or manual labor) can accurately grab the positioned base from the conveyor belt and place it on the dispensing station 2.

[0068] If the product being transported is a finished speaker, it is placed on the conveyor belt from the robotic arm unit 25 and then corrected by the V-shaped positioning part 35 to ensure that the finished product is neatly arranged on the conveyor belt, facilitating accurate grasping or operation by downstream equipment (such as testing equipment and packaging equipment). The synergistic effect of the sensor 34 and the V-shaped positioning part 35 solves the problem of product deviation during transport, ensuring smooth connection between processes, improving the automation and coordination of the production line, and reducing equipment downtime for adjustment due to product deviation, thus ensuring production continuity.

[0069] The overall working principle of this utility model is as follows: First, the speaker base is conveyed to the loading area by the conveyor device 32. After the sensor 34 on the conveyor device 32 detects the base, the control unit 6 adjusts the conveyor belt speed so that the base enters the V-shaped positioning part 35 for precise positioning. Then, the loading mechanism places the positioned base on the dispensing stations 2 arranged around the support platform 17. The control unit 6 drives the drive motor 15 of the drive device 3 to operate, and the cam divider 16 converts the continuous rotation into the intermittent rotation of the support platform 17, driving the dispensing stations 2 to rotate sequentially.

[0070] When the workstation reaches the dispensing area, the first dispensing driver 8 of the dispensing assembly 4 drives the support frame 7 to adjust its overall position, and the second dispensing driver 11 drives multiple circumferentially arranged dispensing guns 9 to precisely align and simultaneously complete the multi-dispensing operation on the front of the base. If lateral glue application is required, the lateral driver 14 of the lateral compensation glue assembly 12 drives the lateral glue gun 13 to adjust its position and uniformly apply glue to the glue application area on the side of the base. After dispensing is completed, the support platform 17 continues to rotate, sending the workstation to the transplanting area. The rotary cylinder 22 of the rotating transplanting structure drives the support arm 23 to rotate to the base storage rack. The clamping assembly 24 picks up the base and resets, accurately placing it on the base of the workstation, completing the initial assembly of the base and the base.

[0071] After assembly, the support platform 17 rotates the workstation containing the finished product to the working range of the robotic arm unit 25. The robotic arm unit 25 drives the gripping component 26 to move according to the preset trajectory. The frustum-shaped groove 31 of the gripper fingers 28 automatically centers and clamps the finished product through guidance. Subsequently, the robotic arm transfers the finished product to the conveying device 32 or the storage box. Throughout the process, the control unit 6 acts as the core, receiving feedback signals from each component in real time, coordinating the rotation rhythm of the drive device 3, the dispensing parameters of the dispensing component 4, the timing of the transfer component 5, and the gripping path of the robotic arm, ensuring seamless connection between the loading, dispensing, assembly, unloading, and conveying stages. The multi-station cyclic operation and the automated coordination of each component realize the continuous and efficient dispensing and assembly in speaker production. At the same time, the positioning flange 19, V-shaped positioning part 35, frustum-shaped groove 31 and other structures ensure the accuracy of each stage, meeting the needs of large-scale production.
