[0001] This utility model relates to the technical field, specifically to a feeding device for the production of loudspeaker accessories. Background Technology

[0002] In the production process of loudspeakers, multiple components such as magnets, diaphragms, and voice coils need to be assembled and processed. The feeding process is a key preliminary step in the production process, and its efficiency and accuracy directly affect the quality and production capacity of subsequent assembly. At present, the feeding of loudspeaker components is mostly carried out by manual assistance or by feeding them onto a conveyor belt by vibration.

[0003] While the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: there are many types of loudspeaker components (such as sheet diaphragms, columnar voice coils, and ring magnets), and the structural forms of different components vary greatly. Existing devices lack effective transfer and positioning. When the components are transferred from the feeding track to the production line, they are prone to positional displacement, which leads to the inability to properly connect the subsequent assembly processes. Based on this, this utility model designs a feeding device for the production of loudspeaker components to solve the above problems. Utility Model Content

[0004] This utility model provides a feeding device for speaker component production. This feeding device can flexibly adjust the spacing to accommodate speaker components of different sizes. Combined with a synchronous adjustment structure driven by a bidirectional threaded rod and the guiding constraint of a trapezoidal slide rail, it achieves precise positioning of the components during transport, reducing offset and gripping errors. Furthermore, it can accurately block components for gripping and positioning. Overall, it balances versatility, precision, and ease of operation, effectively improving feeding quality and production efficiency, and effectively solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for speaker accessory production, comprising a gripping device and a support frame disposed below the gripping device, a conveyor belt mounted on the surface of the support frame, a positioning plate symmetrically slidably connected to the surface of the conveyor belt, a fixing rod symmetrically fixedly connected to the surface of the support frame, and matching limiting grooves symmetrically opened on the surface of the positioning plate, the fixing rods being slidably connected to the positioning plate through the limiting grooves.

[0006] As a preferred embodiment of the feeding device for speaker accessory production according to this utility model, a limit cap is threadedly connected to the end of the fixing rod away from the support frame.

[0007] As a preferred embodiment of the feeding device for speaker component production according to this utility model, a fixing plate is symmetrically arranged below the positioning plate, a bidirectional threaded rod is rotatably connected to the surface of the fixing plate, a moving block is symmetrically threaded to the surface of the bidirectional threaded rod, a connecting plate is rotatably connected to the surface of the moving block, and a fixing block is rotatably connected to the end of the connecting plate away from the moving block, and the fixing block and the positioning plate are fixedly connected.

[0008] As a preferred embodiment of the feeding device for speaker accessory production according to this utility model, a trapezoidal slide rail is fixedly connected to the surface of the fixed plate, and the trapezoidal slide rail and the moving block are slidably connected.

[0009] As a preferred embodiment of the feeding device for speaker component production according to this utility model, a support block is fixedly connected to the surface of the trapezoidal slide rail, the support block and the bidirectional threaded rod are rotatably connected, a driven disc is rotatably connected to the surface of the support block, the driven disc and the bidirectional threaded rod are fixedly connected, a transmission belt is meshed with the surface of the driven disc, a transmission disc is meshed with the end of the transmission belt away from the driven disc, a servo motor is provided on one side of the trapezoidal slide rail, and the output shaft of the servo motor is fixedly connected to the transmission disc.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The sliding cooperation between the fixed rod and the limiting slide groove allows the positioning plate to be symmetrically adjusted in spacing, breaking the limitations of the fixed positioning structure of traditional devices. It can adapt to speaker accessories of different sizes, improving the versatility of the device. At the same time, the positioning plate forms a guide channel to ensure that the accessories are transported along the preset path, reducing grasping errors. The limiting cap locks the position of the positioning plate through a threaded connection, preventing positioning deviation caused by vibration during device operation. It balances adjustment flexibility and positioning stability, and also prevents the positioning plate from falling off, improving operational safety.

[0013] The bidirectional threaded rod drives the moving block to slide synchronously in opposite directions, realizing symmetrical adjustment of the positioning plate and ensuring that the parts are always in the center of the conveyor belt. The trapezoidal slide rail constrains the trajectory of the moving block to avoid circumferential rotation and improve adjustment stability. The servo motor driven transmission system realizes automated adjustment and, together with precise speed control, achieves millimeter-level spacing adjustment, adapts to rapid parts switching, and greatly improves production efficiency. The support block also enhances the rigidity of the threaded rod and reduces mechanical wear.

[0014] The stop bar can prevent the accessory from sliding due to inertia, so that it stops precisely in the gripping area, solving the problem of gripping misalignment. The position of the stop bar can be flexibly adjusted by fixing bolts to adapt to the gripping needs of different accessories. The flexible design can also protect the integrity of vulnerable accessories. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1-4 As shown, this utility model provides a technical solution: a feeding device for speaker accessory production, including a gripping device 1 and a support frame 2 disposed below the gripping device 1. A conveyor belt 3 is installed on the surface of the support frame 2, and a positioning plate 4 is symmetrically slidably connected to the surface of the conveyor belt 3. A fixing rod 5 is symmetrically fixedly connected to the surface of the support frame 2. The surface of the positioning plate 4 is symmetrically provided with matching limiting grooves 6, and the fixing rod 5 is slidably connected to the positioning plate 4 through the limiting grooves 6.

[0025] In this implementation scheme: slidable positioning plates 4 are symmetrically arranged on the surface of the conveyor belt 3, and fixed rods 5 are fixed on the surface of the support frame 2. Limiting grooves 6 adapted to the fixed rods 5 are opened on the positioning plates 4. The fixed rods 5 pass through the limiting grooves 6 to achieve a sliding connection between the two. This solves the problem that the positioning structure of traditional feeding devices is fixed and can only adapt to single-size accessories. The sliding positioning plates 4 can realize the conveying and positioning of multi-specification speaker accessories, improving the versatility of the device. The symmetrical arrangement of the positioning plates 4 forms a guide channel. With the sliding constraint of the fixed rods 5 and the limiting grooves 6, it ensures that the accessories move along the preset path on the conveyor belt 3, avoiding grasping errors caused by deviation. Positioning adjustment is achieved by the sliding cooperation of the fixed rods 5 and the limiting grooves 6. The structure is simple and reliable, reducing the risk of mechanical failure.

[0026] Furthermore:

[0027] like Figures 1 to 4 As shown:

[0028] In an optional embodiment, a limit cap 7 is threaded to the end of the fixing rod 5 away from the support frame 2.

[0029] In this embodiment: a limiting cap 7 is threadedly connected to the end of the fixing rod 5 away from the support frame 2. After the positioning plate 4 is adjusted to the position that matches the size of the accessory, tightening the limiting cap 7 can fix the positioning plate 4, preventing it from sliding due to vibration during device operation and ensuring positioning stability. The limiting cap 7 can prevent the positioning plate 4 from detaching from the end of the fixing rod 5, thus preventing production accidents or device damage caused by parts falling off during equipment operation.

[0030] Furthermore:

[0031] like Figures 1 to 4 As shown:

[0032] In an optional embodiment, a fixing plate 8 is symmetrically arranged below the positioning plate 4. A bidirectional threaded rod 9 is rotatably connected to the surface of the fixing plate 8. A moving block 10 is symmetrically threaded to the surface of the bidirectional threaded rod 9. A connecting plate 11 is rotatably connected to the surface of the moving block 10. A fixing block 12 is rotatably connected to the end of the connecting plate 11 away from the moving block 10. The fixing block 12 and the positioning plate 4 are fixedly connected.

[0033] In this embodiment: a fixed plate 8 is symmetrically arranged below the positioning plate 4, and a bidirectional threaded rod 9 is rotatably installed on the fixed plate 8. Moving blocks 10 are symmetrically connected to the surface of the rod. The moving blocks 10 are rotatably connected to the fixed blocks 12 fixed on the positioning plate 4 through the connecting plate 11. When the bidirectional threaded rod 9 rotates, the moving blocks 10 on both sides slide synchronously in opposite directions under the action of the positive and negative threads. The connecting plate 11 pushes or pulls the positioning plate 4 to move along the fixed rod 5 to achieve spacing adjustment. With the help of the characteristics of the bidirectional threaded rod 9, the positioning plates 4 on both sides can move closer or further away at the same time, ensuring that the accessories are always in the center position of the conveyor belt 3 during the adjustment process, avoiding positioning offset caused by unilateral adjustment. The thread transmission of the bidirectional threaded rod 9 has high displacement control accuracy, and compared with manual adjustment, it can more accurately adapt to speaker accessories of different thicknesses and diameters.

[0034] Furthermore:

[0035] like Figures 1 to 4 As shown:

[0036] In an optional embodiment, a trapezoidal slide rail 13 is fixedly connected to the surface of the fixed plate 8, and the trapezoidal slide rail 13 and the moving block 10 are slidably connected.

[0037] In this embodiment: the trapezoidal slide rail 13 refers to a guide rail structure with a trapezoidal cross section. The moving block 10 has a matching trapezoidal groove inside, and the two form a fitting sliding fit. The trapezoidal slide rail 13 can restrict the moving block 10 to slide only along the axial direction of the rod body, preventing it from rotating axially with the rotation of the bidirectional threaded rod 9, thus ensuring the stability of the adjustment action. Compared with ordinary rectangular slide rails, the trapezoidal structure has better lateral support, can withstand the pressure of the accessories transmitted by the positioning plate 4, reduce deformation during the transmission process, and extend the service life of the device.

[0038] Furthermore:

[0039] like Figures 1 to 4 As shown:

[0040] In an optional embodiment, a support block 14 is fixedly connected to the surface of the trapezoidal slide rail 13. The support block 14 is rotatably connected to the bidirectional threaded rod 9. A driven disk 15 is rotatably connected to the surface of the support block 14. The driven disk 15 is fixedly connected to the bidirectional threaded rod 9. A transmission belt 16 is meshed with the surface of the driven disk 15. A transmission disk 17 is meshed with the end of the transmission belt 16 away from the driven disk 15. A servo motor 18 is provided on one side of the trapezoidal slide rail 13. The output shaft of the servo motor 18 is fixedly connected to the transmission disk 17.

[0041] In this implementation scheme: a support block 14 is fixed on the trapezoidal slide rail 13 to enhance the rotational stability of the bidirectional threaded rod 9. A driven disk 15 fixed to the bidirectional threaded rod 9 is installed on the support block 14. The driven disk 15 meshes with the transmission disk 17 through the transmission belt 16. The transmission disk 17 is driven to rotate by the servo motor 18. The servo motor 18 has precise speed and angle control capabilities. With the stable transmission of the conveyor belt 3, it can achieve millimeter-level adjustment of the spacing between the positioning plates 4, meeting the high-precision feeding requirements of speaker accessories. The support block 14 can reduce the cantilever deformation of the bidirectional threaded rod 9. The transmission of the conveyor belt 3 can better buffer the impact than gear meshing and reduce the mechanical loss in the power transmission process.

[0042] Furthermore:

[0043] like Figures 1 to 4 As shown:

[0044] In an optional embodiment, a stop bar 19 is provided below the gripping device 1, and a fixing bolt 20 is threadedly connected to the surface of the stop bar 19. The fixing bolt 20 is threadedly connected to the support frame 2.

[0045] In this embodiment: when the accessory is conveyed to the gripping area by the conveyor belt 3, the baffle 19 can prevent the accessory from moving further and keep it at a preset position directly below the gripping device 1. This solves the problem of gripping misalignment caused by the inertia of the conveyor belt 3. The threaded connection of the fixing bolt 20 makes it easy to adjust the installation position of the baffle 19. It can be flexibly positioned according to the gripping point requirements of different accessories, thus improving the adaptability of the device.

[0046] Working Principle: Sliding positioning plates 4 are symmetrically arranged on the surface of the conveyor belt 3, while fixing rods 5 are fixed on the surface of the support frame 2. Limiting grooves 6, adapted to the fixing rods 5, are formed on the positioning plates 4. The fixing rods 5 slide into the limiting grooves 6, achieving a sliding connection between the two. This solves the problem of traditional feeding devices having fixed positioning structures and only being able to accommodate single-size parts. The sliding positioning plates 4 enable the conveying and positioning of speaker parts of various specifications, improving the device's versatility. The symmetrical arrangement of the positioning plates 4 forms a guide channel, and the sliding constraint of the fixing rods 5 and the limiting grooves 6 ensures that the parts move along a preset path on the conveyor belt 3, avoiding grasping errors caused by deviation. Positioning adjustment is achieved through the sliding cooperation of the fixing rods 5 and the limiting grooves 6. The structure is simple and reliable, reducing the risk of mechanical failure. A limit cap 7 is threadedly connected to the end of the fixed rod 5 away from the support frame 2. After the positioning plate 4 is adjusted to the position that matches the size of the accessory, tightening the limit cap 7 can fix the positioning plate 4, preventing it from sliding due to vibration during device operation and ensuring positioning stability. The limit cap 7 can also prevent the positioning plate 4 from detaching from the end of the fixed rod 5, preventing production accidents or device damage caused by parts falling off during equipment operation. A fixed plate 8 is symmetrically arranged below the positioning plate 4. A bidirectional threaded rod 9 is rotatably installed on the fixed plate 8. Moving blocks 10 are symmetrically connected to the surface of the rod. The moving blocks 10 are rotatably connected to the fixed blocks 12 fixed on the positioning plate 4 through the connecting plate 11. When the bidirectional threaded rod 9 rotates, the moving blocks 10 on both sides slide synchronously in opposite directions under the action of the positive and negative threads, and are pushed by the connecting plate 11. The positioning plate 4 is moved or pulled along the fixed rod 5 to adjust the spacing. Utilizing the characteristics of the bidirectional threaded rod 9, the two positioning plates 4 can move closer or further apart simultaneously, ensuring that the components remain centered on the conveyor belt 3 during adjustment, avoiding positioning offset caused by unilateral adjustment. The threaded transmission of the bidirectional threaded rod 9 has high displacement control precision, allowing for more accurate adaptation to speaker components of different thicknesses and diameters compared to manual adjustment. The trapezoidal slide rail 13 refers to a guide rail structure with a trapezoidal cross-section. The moving block 10 has a matching trapezoidal groove inside, forming a sliding fit. The trapezoidal slide rail 13 restricts the moving block 10 to slide only along the axial direction of the rod, preventing axial rotation as the bidirectional threaded rod 9 rotates, ensuring the stability of the adjustment action. Compared to ordinary... The rectangular slide rail provides better lateral support, can withstand the pressure of the accessories transmitted by the positioning plate 4, reduces deformation during transmission, and extends the service life of the device. A support block 14 is fixed on the trapezoidal slide rail 13 to enhance the rotational stability of the bidirectional threaded rod 9. A driven disc 15, fixed to the bidirectional threaded rod 9, is mounted on the support block 14. The driven disc 15 meshes with a transmission disc 17 via a transmission belt 16. The transmission disc 17 is driven to rotate by a servo motor 18, which has precise speed and angle control capabilities. Combined with the stable transmission of the conveyor belt 3, it enables millimeter-level adjustment of the spacing between the positioning plates 4, meeting the high-precision feeding requirements of speaker accessories. The support block 14 reduces the cantilever deformation of the bidirectional threaded rod 9, and the transmission belt 3 provides better shock absorption compared to gear meshing.To reduce mechanical losses during power transmission, when the part is conveyed to the gripping area by the conveyor belt 3, the stop bar 19 can prevent the part from moving further, stopping it at a preset position directly below the gripping device 1. This solves the problem of gripping misalignment caused by the inertia of the conveyor belt 3. The threaded connection of the fixing bolt 20 facilitates adjustment of the installation position of the stop bar 19, allowing for flexible positioning according to the gripping point requirements of different parts, thus improving the adaptability of the device.
