Description

Technical Field

[0001] This utility model relates to the field of speaker dispensing technology, and in particular to an automatic dispensing and transfer machine. Background Technology

[0002] In the field of automated dispensing production for loudspeakers, traditional equipment often faces numerous bottlenecks. Regarding space utilization, loudspeaker carriers are mostly arranged horizontally, resulting in limited storage capacity within the same footprint, leading to redundant equipment size and difficulty adapting to compact workshop layouts. In terms of loading and unloading efficiency, carriers often rely on manual stacking or single-unit drive lifting, resulting in cumbersome positioning and calibration, long intervals between pick-up and drop, and inability to match the pace of mass production. Furthermore, traditional equipment often uses a single-area storage design for carriers, leading to the mixing of carriers awaiting processing and finished products, increasing material management complexity. At the same time, disorderly stacking of carriers can cause collisions and wear, increasing replacement costs. Therefore, an automated dispensing and transfer machine is needed.

[0008] Preferably, the turntable mechanism includes a turntable motor mounted on the top of the mounting plate of the frame, and a turntable divider mounted on the top of the mounting plate of the frame.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-17 An automatic dispensing and transfer machine includes a frame 1, a carrier stack base frame 2 mounted on one side of the frame 1, carrier loading / unloading mechanisms 3 mounted on both sides of the top of the carrier stack base frame 2, a partition plate 31 mounted on the top center of the carrier stack base frame 2, and two carrier loading / unloading mechanisms 3 located at opposite ends of the partition plate 31. Each carrier loading / unloading mechanism 3 includes a horn-shaped carrier 32, and the mechanism enables loading or unloading of the horn-shaped carrier 32. The mechanism also includes a carrier drive motor 34 installed inside the carrier stack base frame 2. Guide posts 35 are mounted on both sides of the bottom of the partition plate 31. Multiple... The bottom of each guide post 35 is installed on the top of the vehicle stack frame 2. A drive screw 36 is provided between the two guide posts 35 on each side of the isolation plate 31. The top of the drive screw 36 is rotatably connected to the top of the isolation plate 31 through a bearing. The bottom of the drive screw 36 is fixedly installed to the output end of the vehicle drive motor 34 through a coupling. The threaded surface of the drive screw 36 is threadedly connected to a support base 37. The two sides of the support base 37 are also slidably inserted into the surfaces of the two guide posts 35. A stack frame 38 is installed on the top of the support base 37. Multiple horn vehicles 32 are arranged linearly in a vertical direction inside the stack frame 38.

[0016] Specifically, this vertical stacking structure can accommodate several times the number of speaker carriers 32 compared to a horizontal layout within the same floor area. The space on the bottom frame 2 of the carrier rack on one side of the equipment rack 1 is limited, so the partition plate 31 divides it into two independent carrier storage areas. The rack frames 38 in each area support the speaker carriers 32 through vertical stacking, which avoids the problem of excessive equipment size caused by horizontal expansion while meeting the carrier storage requirements of mass production.

[0017] When the drive motor rotates the drive screw 36, the supporting base 37 moves linearly along the guide post 35 via threaded transmission, and the vertically arranged horn carriers 32 perfectly match this movement trajectory. When loading is required, the drive system can drive the stack frame 38 to gradually descend, keeping the horn carriers 32 at a fixed height that is easy for the robot arm 4 or the picking mechanism to grasp, without the need for additional adjustment of the carrier's horizontal position; when unloading, the carriers filled with horns can be stacked layer by layer into the stack frame 38, and the drive system receives and stores them in sequence. The entire process does not require complex positioning calibration, realizing continuous "picking-stacking" action, greatly shortening the auxiliary time for loading and unloading, and improving the efficiency of single-batch carrier processing.

[0018] Carrier placement plates 33 are installed on both sides of the top right end of the frame 1. The horn carrier 32 is placed on the carrier placement plates 33. A robot arm 4 is installed at the center of the top right end of the frame 1. A clamping mechanism 5 is provided at the drive end of the robot arm 4. The clamping mechanism 5 includes a horn body 51. The clamping mechanism 5 realizes the action of placing the horn body 51 on the horn carrier 32 under the drive of the robot arm 4 after clamping. The clamping mechanism 5 also includes a clamping plate 52. Pneumatic grippers 53 are installed at the four corners of the bottom end of the clamping plate 52. The four pneumatic grippers 53 are rectangularly distributed at the bottom of the clamping plate 52, and the clamping positions of the bottom ends of the four pneumatic grippers 53 correspond to the four horn bodies 51 placed on the top of the horn fixture 91.

[0019] Specifically, the rectangular distribution of the four pneumatic grippers 53 corresponds to the four speaker bodies 51 on the speaker fixture 91. The core advantage lies in achieving a synchronous operation mode of "clamping multiple products at once," breaking the efficiency bottleneck of traditional single-station clamping. When the robotic arm 4 drives the clamping mechanism 5 to move, the four pneumatic grippers 53 can simultaneously align with the four speaker bodies 51 inside the speaker fixture 91 on the carrier placement plate 33, completing the gripping action through synchronous airflow. Subsequently, driven by the robotic arm 4, the four speaker bodies 51 are simultaneously placed onto the corresponding speaker carriers 32. Compared to the method of gripping and placing one by one with a single gripper, this design increases the product throughput per operation by up to four times, significantly reducing the number of times the robotic arm 4 moves back and forth and the clamping time for a single batch of products. It is particularly suitable for batch production scenarios, significantly improving the overall capacity of the equipment.

[0020] The top left end of the frame 1 is equipped with a dispensing mechanism 6, a turntable mechanism 7, a fixture loading and unloading mechanism 8, and a conveying mechanism 9.

[0021] Two dispensing mechanisms 6 are arranged perpendicularly at 90 degrees to the rotation axis of the turntable mechanism 7. The dispensing mechanism 6 realizes the dispensing action of the speaker body 51. The dispensing mechanism 6 includes a dispensing base 61 installed on the top of the mounting plate of the frame 1. A dispensing cylinder 62 is installed on the top of the dispensing base 61. A dispensing drive plate 63 is installed on the telescopic end of the dispensing cylinder 62. A dispensing slide rod 64 is also installed between the two mounting plates on the top of the dispensing base 61. The surfaces of the two dispensing slide rods 64 are slidably inserted into the two ends of the dispensing drive plate 63. A dispensing connecting plate 65 is installed at the bottom of one end of the dispensing drive plate 63. A needle-type glue gun 66 is installed on the surface of the dispensing connecting plate 65. The four needle-type glue guns 66 are arranged in a rectangular pattern. The dispensing positions of the four needle-type glue guns 66 correspond to the dispensing positions of the four speaker bodies 51 placed on the top of the speaker fixture 91 at the bottom.

[0022] Specifically, the 90-degree vertical distribution of the two dispensing mechanisms 6 perfectly matches the rotational characteristics of the turntable mechanism 7, creating a continuous "loading-dispensing-unloading" workflow and completely breaking through the waiting bottleneck of single-mechanism dispensing. The turntable mechanism 7 can drive the station carrying the speaker fixture 91 to rotate in a stepwise manner. When one station, carrying the speaker body 51 to be dispensed, rotates to below the first dispensing mechanism 6, that mechanism starts to complete the dispensing of the designated area. At the same time, the other station can move to below the second dispensing mechanism 6 under the turntable's drive to complete the subsequent dispensing process. This layout allows the two dispensing mechanisms 6 to operate in parallel. During the turntable rotation, there is no need to wait for a single mechanism to complete the dispensing action, achieving a seamless connection between "station flow and dispensing action," significantly shortening the total dispensing time for a single batch of products, and is especially suitable for the high-efficiency operation requirements in mass production scenarios.

[0023] The rectangular distribution of the four ejector-type glue guns 66 in each dispensing mechanism 6 and their corresponding arrangement with the speaker body 51 enables "simultaneous dispensing of multiple parts at a single station," significantly increasing the product throughput per unit time. The top of the speaker fixture 91 can simultaneously hold four speaker bodies 51 in a rectangular arrangement, and the spacing and arrangement of the four ejector-type glue guns 66 perfectly match the dispensing positions of the speaker bodies 51. When the dispensing cylinder 62 drives the ejector-type glue guns 66 downwards, the four glue guns can simultaneously align with the preset dispensing positions of the four speaker bodies 51, completing the dispensing of four products in one go. Compared to the traditional method of processing one glue gun at a time, this design increases the dispensing efficiency of a single station by up to four times, while avoiding the time loss from frequent glue gun repositioning, making the dispensing process more efficient and compact.

[0024] A dispensing mechanism 6 is further provided with a dispensing rotation mechanism 10 at its bottom. The dispensing rotation mechanism 10 includes a dispensing rotation base 101, with dispensing rotation columns 102 slidably inserted into each of the four corners of the dispensing rotation base 101. Dispensing rotation drive plates 103 are fixedly installed at the bottom of each of the four dispensing rotation columns 102. A dispensing support plate 104 is installed at the bottom of the dispensing rotation base 101, and a dispensing drive cylinder 105 is installed at the bottom of the dispensing support plate 104. The telescopic top of the dispensing drive cylinder 105 is installed at the bottom of the dispensing rotation drive plate 103. A dispensing rotation motor 106 is installed at the top of the dispensing rotation drive plate 103. A dispensing gear plate 107 is installed at the top of each of the four dispensing rotation columns 102. Each corner and top is rotatably connected to a dispensing drive shaft 108 via bearings. A dispensing driven gear 109 is fixedly mounted on the bottom arc surface of the dispensing drive shaft 108. The output end of the dispensing rotary motor 106 passes through and extends to the top of the dispensing gear plate 107 and is equipped with a gear shaft 1010. A drive gear 1011 is mounted on the top of the gear shaft 1010. The tooth grooves of the four dispensing driven gears 109 mesh with the teeth of the drive gear 1011. A plug-in limiting seat 1012 is mounted on the top of the dispensing drive shaft 108. The plug-in limiting seat 1012 extends through the dispensing drive cylinder 105 to be plugged into the bottom of the speaker body 51 placement plate of the speaker fixture 91. The surface of the speaker body 51 placement plate is rotatably set with respect to the surface of the speaker fixture 91.

[0025] Specifically, the core value of the dispensing rotation mechanism 10 lies in overcoming the limitations of fixed dispensing, allowing the speaker body 51 to rotate around its own axis, satisfying multi-directional, annular, or arc-shaped dispensing needs. When the area to be dispensed on the speaker body 51 is annular, such as the connection between the speaker voice coil and the housing, traditional fixed dispensing methods require moving the dispensing mechanism 6 or adjusting the position of the fixture to achieve full coverage, which is not only inefficient but also prone to dispensing gaps. In this rotation mechanism, the dispensing rotation motor 106 drives four dispensing driven gears 109 to rotate synchronously through the drive gear 1011, thereby driving the dispensing drive shaft 108 and the top insertion limiting seat 1012 to rotate. After the insertion limiting seat 1012 is inserted and fixed to the bottom of the speaker body 51 placement tray, it can drive the placement tray and the speaker body 51 above it to rotate at a uniform speed. With the fixed dispensing position of the needle-type glue gun 66, continuous circular dispensing can be completed during the rotation of the speaker body 51, without the need for frequent adjustment of the glue gun or fixture, which greatly expands the process adaptability range of the equipment and can meet the dispensing needs of speaker products with different structures.

[0026] The structure of the dispensing drive cylinder 105 driving the dispensing rotary drive plate 103 and related components to rise and fall enables rapid and stable docking and separation of the insertion limit seat 1012 and the speaker body 51 placement tray, improving the efficiency of process connection. When the speaker fixture 91 moves to the dispensing station with the turntable mechanism 7, the top of the dispensing drive cylinder 105 extends, pushing the dispensing rotary drive plate 103 to move upward along the dispensing rotary column 102, so that the insertion limit seat 1012 is accurately inserted into the positioning hole at the bottom of the speaker body 51 placement tray, completing the mechanical locking; after the dispensing is completed, the cylinder retracts, driving the insertion limit seat 1012 to descend and disengage from the placement tray, and the turntable mechanism 7 can then drive the fixture to the next process. The advantages of this lifting design are: first, the adhesive-coated rotating column 102 guides the drive plate, ensuring the verticality of the insertion limit seat 1012 during the lifting process and avoiding jamming or offset during docking; second, the mechanical insertion locking method can transmit rotational torque more reliably than traditional adsorption or clamping, preventing slippage when the speaker body 51 rotates; and third, the lifting action responds quickly and can be precisely matched with the flow rhythm of the turntable station, reducing the waiting time for process connection.

[0027] The turntable mechanism 7 enables the speaker body 51 placed on top of the turntable to rotate and switch processing positions. The turntable mechanism 7 includes a turntable motor 71 mounted on the top of the mounting plate of the frame 1. A turntable divider 72 is also mounted on the top of the mounting plate of the frame 1. An input synchronous pulley 73 is mounted on the input end of the turntable divider 72, and an output synchronous pulley 74 is mounted on the output end of the turntable motor 71. Both the output synchronous pulley 74 and the input synchronous pulley 73 transmit motion through a synchronous belt. A dispensing turntable 75 is mounted on the output end of the turntable divider 72. A fixture limiting block 76 is mounted on the top of the dispensing turntable 75. The speaker fixture 91 is engaged with the surfaces of the two fixture limiting blocks 76. The fixture limiting blocks 76 are pushed and limited or released by the extension and retraction movement of the starting cylinder below.

[0028] Specifically, the turntable mechanism 7 employs a "motor-synchronous belt-divider" transmission combination, fundamentally ensuring the rotational positioning accuracy of the dispensing turntable 75 and providing a foundation for precise alignment of various processes. Synchronous belt transmission features smooth transmission, low noise, and no slippage. The turntable motor 71 precisely transmits power to the input synchronous belt pulley 73 via the output synchronous belt pulley 74 and the synchronous belt, avoiding the impact and wear of gear transmission and ensuring continuous power transmission. The turntable divider 72, as the core positioning component, converts the continuous rotation of the motor into the step-by-step rotation of the dispensing turntable 75, achieving a dividing accuracy down to the second level. This allows the turntable to precisely stop the speaker fixture 91 at preset dispensing, loading, and unloading positions without any positional deviation. This high-precision transmission design solves the problem of large rotational positioning errors in traditional turntables, ensuring that the ejector-type glue gun 66, clamping mechanism 5, etc., can accurately align with the speaker body 51, improving the process qualification rate.

[0029] Two conveying mechanisms 9 are located on both sides of the fixture loading and unloading mechanism 8. The conveying mechanism 9 includes a horn fixture 91. One conveying mechanism 9 realizes the action of conveying the horn body 51 placed in the horn fixture 91 into the turntable mechanism 7 for loading. The other conveying mechanism 9 realizes the action of conveying the empty tray after the horn body 51 placed in the horn fixture 91 is glued and unloaded. The conveying mechanism 9 includes a conveying base 92 installed on the top of the mounting plate of the frame 1. Both ends of the top of the conveying base 92 are rotatably connected to the conveying rollers 93 through bearings. A conveying motor 94 is installed on one side of the conveying base 92. Tensioning wheels 95 are also rotatably connected to both sides of the conveying base 92 through bearings. The surface of the pulley at the output end of the conveying motor 94, the surface of the conveying rollers 93, and the surface of the tensioning wheels 95 are all connected to the conveying belt 96.

[0030] Specifically, the clear functional division of the two conveying mechanisms 9 completely solves the problem of jig mixing, forming a highly efficient closed-loop flow of "waiting for processing - processing - recycling". One conveying mechanism 9 specifically receives the horn jig 91 carrying the horn body 51 to be glued, and stably transports it to the gripping position of the jig loading and unloading mechanism 8, continuously supplying "raw material jigs" to the turntable mechanism 7; the other conveying mechanism 9 simultaneously receives the empty horn jig 91 after glue dispensing, realizing centralized recycling and reuse of jigs. This partitioned design makes the jig flow direction clear and controllable, avoiding collisions and confusion between jigs to be processed and empty jigs during the conveying process. Operators only need to periodically replenish jigs to be processed to the feeding conveying mechanism 9 and sort out empty jigs from the discharging conveying mechanism 9, greatly reducing the complexity of material management and improving the orderliness of production flow.

[0031] The fixture loading and unloading mechanism 8 realizes the action of loading the speaker fixture 91, which holds the speaker body 51, onto the turntable mechanism 7. The fixture loading and unloading mechanism 8 includes a loading and unloading motor 81 installed inside the frame 1. The output end of the loading and unloading motor 81 is equipped with a loading and unloading main synchronous pulley 82. The top of the mounting plate of the frame 1 is also equipped with a loading and unloading divider 83. The input end of the loading and unloading divider 83 is equipped with a loading and unloading slave synchronous pulley 84. Both the loading and unloading main synchronous pulley 82 and the loading and unloading slave synchronous pulley 84 are driven by synchronous belts. The output end of the loading and unloading divider 83 is equipped with a swing arm 85. Both ends of the swing arm 85 are equipped with swing cylinder grippers 86. The swing cylinder grippers 86 realize the horizontal reciprocating motion to clamp the speaker fixture 91.

[0032] Specifically, the fixture loading / unloading mechanism 8 employs a combined transmission method of "loading / unloading motor 81 + synchronous belt + divider," fundamentally ensuring the stepping motion and precise positioning of the swing arm 85, providing a foundation for the smooth transfer of the fixture. The loading / unloading motor 81 transmits power to the loading / unloading slave synchronous belt pulley 84 via the main synchronous belt pulley 82. The synchronous belt drive has the characteristics of no slippage and smooth transmission, avoiding errors in the power transmission process. The loading / unloading divider 83, as a core positioning component, converts the continuous rotation of the motor into the intermittent swing of the swing arm 85. Its dividing accuracy can reach the second level, driving the swing arm 85 to precisely stop the gripper at the material picking position of the conveyor mechanism 9 and the material unloading position of the turntable mechanism 7, ensuring that the horn fixture 91 can accurately dock, avoiding problems such as fixture collisions and detachment caused by positioning deviations. This high-precision transmission design controls the fixture transfer error within the millimeter level, perfectly matching the station positioning requirements of the turntable mechanism 7, providing a prerequisite guarantee for the accuracy of the subsequent dispensing process.

[0033] The symmetrically mounted swing cylinder grippers 86 at both ends of the swing arm 85 are the core design for improving transfer efficiency, achieving a highly efficient "one-swing, two-way operation" mode. When the swing arm 85 swings to one side of the conveyor mechanism 9 under the drive of the divider, the cylinder gripper at one end can accurately grab the fixture carrying the speaker body 51 to be glued; at the same time, the gripper at the other end of the swing arm 85 can simultaneously grab the empty fixture that has been glued on the turntable mechanism 7. Then the swing arm 85 rotates 90 degrees, placing the fixture to be processed onto the loading station of the turntable, while transferring the empty fixture to the unloading conveyor mechanism 9 on the other side. This "simultaneous picking and unloading" mode completely avoids the time-consuming repetitive action of "picking up-returning-unloading" of the traditional single gripper, shortening the single transfer cycle by more than 50%, and making the fixture transfer rhythm perfectly match the stepping rotation rhythm of the turntable mechanism 7, ensuring that the turntable station is "filled as soon as it is empty" without waiting time.

[0034] The 86-type swing cylinder gripper is designed to clamp the fixture through horizontal reciprocating motion, which improves the reliability of clamping and effectively protects the fixture structure. The horizontal reciprocating motion causes the gripper to form a "ring-like" clamping from both sides of the fixture. Compared with vertical clamping, this method can evenly distribute the clamping force on the sides of the fixture, avoiding tilting or deformation of the fixture due to uneven force. At the same time, the clamping force of the cylinder gripper can be precisely controlled by adjusting the air pressure, which can ensure that the fixture remains stable during swing transfer and avoid scratches or structural damage to the fixture surface caused by rigid clamping.

[0035] The technical solution of this automatic dispensing and transfer machine has significant advantages, specifically as follows: In terms of space utilization, the vertically stacked design of the horn-shaped carriers 32 allows for the storage of several times the number of carriers within a limited pallet space. The partition plate 31 separates the carriers to be processed from the finished products, preventing cross-contamination and saving floor space. Work efficiency is greatly improved. The clamping mechanism 5 uses four pneumatic grippers 53 to simultaneously pick up and place four products, the dispensing mechanism 6 uses four glue guns simultaneously, and the dual dispensing mechanisms 6 are distributed at 90 degrees and work in conjunction with the rotating turntable to achieve seamless process connections. The fixture loading and unloading mechanism 8 uses dual grippers for synchronous pick-and-place, improving transfer efficiency, and the dual conveying mechanism 9 creates a closed-loop flow, ensuring continuous material supply. Process quality is more stable. Each mechanism uses a high-precision transmission system of "motor-synchronous belt-divider," combined with guide pillars 35 for precise positioning of carriers and fixtures. The dispensing rotation mechanism 10 achieves horn-shaped ring dispensing, avoiding discontinuity, and the pneumatic grippers 53 provide controllable clamping force, reducing damage to products and fixtures. The equipment is highly adaptable and can be adapted to various speaker specifications by adjusting the gripper stroke and glue gun position. The modular structure makes maintenance convenient, requiring only periodic inspection of vulnerable parts, reducing operation and maintenance costs and downtime, and providing an efficient and stable automated solution for mass speaker processing.

[0036] Working Principle: Fixture Loading and Conveying: The speaker fixture 91, carrying the speaker body 51 to be glued, is smoothly conveyed by the conveyor belt 96 of the left conveying mechanism 9 to the preset gripping position of the fixture loading and unloading mechanism 8. The conveyor motor 94 drives the conveyor belt 96 through pulleys and tensioning pulleys 95 to ensure precise positioning of the fixture. Fixture loading and unloading mechanism 8 starts, and the loading and unloading motor 81 drives the divider through the synchronous belt, causing the swing arm 85 to swing to the left conveying mechanism 9. The cylinder gripper at one end of the swing arm 85 extends horizontally to accurately grip the fixture to be processed; at the same time, the gripper at the other end grabs the empty fixture that has been glued on the turntable. Then the swing arm 85 rotates 90 degrees and places the fixture to be processed between the fixture limit blocks 76 on the turntable. The cylinder drives the limit blocks to squeeze and fix the fixture, and the empty fixture is transferred to the right recycling conveyor belt 96.

[0037] The turntable motor 71 drives the divider via a synchronous belt, causing the turntable to rotate 90 degrees clockwise, transferring the fixture to be processed to below the first dispensing mechanism 6. The drive cylinder of the dispensing rotation mechanism 10 pushes the insertion limit seat 1012 upward, inserting it into the bottom of the speaker body 51 placement tray to complete the locking; the rotary motor drives the placement tray to rotate via the gear set, while the dispensing cylinder 62 drives four sets of ejector-type glue guns 66 to descend along the slide bar, synchronously dispensing glue to the designated areas of the four speaker bodies 51 on the fixture. The turntable rotates 90 degrees clockwise again, and the fixture moves to below the second dispensing mechanism 6. This mechanism starts according to the preset program, and the ejector-type glue guns 66 descend to complete the remaining dispensing process, ensuring that the speaker bodies 51 are fully and completely dispensed.

[0038] The turntable continues to rotate 90 degrees clockwise, and the fixture with the glued parts arrives at the working area of ​​the robot arm 4. The robot arm 4 drives the clamping mechanism 5 to move, and the four sets of pneumatic grippers 53 at the bottom of the clamping plate 52 simultaneously grip the finished horn on the fixture and accurately place it into the horn carrier 32 on the carrier placement plate 33. The fixture loading and unloading mechanism 8 repeats the operation, grabbing the empty fixture to the right-side recycling conveyor belt 96, while simultaneously transferring the new fixture to be processed on the left-side conveyor belt 96 to the turntable, realizing the continuous circulation of fixtures. The steps are repeated until the current horn carrier 32 is full of finished products. The robot arm 4 pushes the full-loaded carrier back into the stack frame 38, and the carrier drive motor 34 drives the drive screw 36 to rotate, causing the support base 37 to descend along the guide post 35, sending the next layer of empty carriers to the grabbing height to continue receiving finished products. When all the carriers in the stack frame 38 are full, one batch of production is completed, and the operator can then uniformly process the full-loaded stack.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
