Description

Technical Field

[0001] This utility model relates to a feeding device, specifically a T-iron feeding device, belonging to the field of loudspeaker manufacturing technology. Background Technology

[0002] The T-iron is the base of a loudspeaker and a crucial component in the speaker enclosure. During loudspeaker production, the T-iron needs to be assembled with the coil and diaphragm. In current technology, the T-iron is assembled manually, but this manual operation poses a danger to workers. Furthermore, the loading speed is typically controlled by a servo motor, which is not adjustable, thus affecting equipment requirements.

[0003] A search revealed the following patent number: 202110151477.X. A T-iron feeding device is described: "A servo motor in the material conveying assembly drives a rotating plate to rotate. When the rotating plate rotates the connecting plate to the side near the material receiving assembly, the connecting plate is subjected to downward pressure from the control plate. At this time, the spring is in a stretched state, causing the connecting plate to extend the magnet block out of the baffle through the connecting rod. The attraction between the magnets attracts the T-iron on the material receiving assembly. Then, the rotation of the servo motor causes the T-iron to rotate above the processing position. When it rotates above the processing position, it is no longer subjected to downward pressure from the control plate. Simultaneously, due to the spring's rebound force, the spring carries the connecting plate towards the rotating plate. The connecting plate, through the connecting rod, carries the magnet block towards the rotating plate, retracting the magnet block into the baffle. Due to the action of the baffle, the T-iron on the magnet block is deflected onto the processing position, thus realizing the automatic feeding and unloading process."

[0004] The device uses the attraction of a magnet to pick up T-shaped iron pieces. However, when the T-shaped iron pieces are conveyed to the bottom of the magnet, it is impossible to classify them as positive or negative, resulting in T-shaped iron pieces being delivered in both positive and negative positions, or even skewed. The inability to directly pick up and feed the T-shaped iron pieces leads to T-shaped iron pieces being delivered in both positive and negative positions, affecting the efficiency of subsequent processing. Utility Model Content

[0005] The purpose of this invention is to provide a T-iron feeding device to solve the above-mentioned problems. When the push rod slides out of the guide groove and enters the bottom of the fixed plate, the push rod is pushed down by the resistance, causing the push rod to drive the clamp to engage with the top of the material, thus clamping the center of the top of the T-iron. When the T-iron is tilted or placed upside down, the bottom of the clamp cannot pick up the T-iron, causing the T-iron to be pushed out and retracted. The clamped material is transported to the feeding worktable position by the rotation of the turntable. At this time, the push rod re-enters the guide groove and rises under the resistance of the return spring, realizing the unloading. This process is repeated to realize the picking, transfer, and unloading of materials. The operation is convenient and efficient. At the same time, it can screen materials to keep them in the same posture during feeding, which is convenient for subsequent processing.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a T-iron feeding device, comprising a conveying mechanism, the conveying mechanism comprising a base, a fixed plate fixedly connected to the top of the base, a turntable rotatably connected to the outer side of the top of the base, the turntable being located at the bottom of the fixed plate, a plurality of material picking mechanisms mounted on the turntable, each material picking mechanism comprising a push rod, a plurality of push rods slidably connected at the edge of the turntable in an annular equidistant distribution via a return spring, a sleeve respectively installed at the bottom of the plurality of push rods, a through groove provided on the outer side of the bottom of the sleeve, a plurality of fixed sleeves slidably connected at the bottom of the turntable in an annular equidistant distribution, the bottom of the plurality of push rods and the sleeves respectively slidably connected to the inside of the fixed sleeves, a 180-degree guide groove provided at the bottom edge of the fixed plate, one end of the guide groove having a certain slope.

[0007] Preferably, the base has a frustum-shaped structure, and a drive assembly is installed at the bottom of the base, which is connected to the bottom of the turntable.

[0008] Preferably, the bottom edge of the jacket is provided with multiple through grooves, and the inner and outer edges of the bottom of the jacket are arc-shaped structures.

[0009] Preferably, multiple rubber blocks are installed on the inner sidewalls of the bottom of the multiple jackets, and the rubber blocks have a trapezoidal structure.

[0010] Preferably, a fixing ring is fixedly connected to the bottom of the fixing sleeve, and the area of ​​the fixing ring is larger than the outer diameter of the fixing sleeve.

[0011] Preferably, a slide rod is slidably connected to the inner side of the bottom of the top rod via a buffer spring, and the top of the sleeve is threadedly connected to the bottom of the slide rod.

[0012] Preferably, a ball bearing is rotatably connected at the center of the top of the top rod, and the ball bearing is in rolling connection with the guide groove and the bottom of the fixed plate.

[0014] Preferably, a collection box is installed at the bottom of the conveyor plate, and one end of the collection box extends to the outside of the turntable.

[0015] The beneficial effects of this utility model are as follows: the base supports the fixed plate for stable installation, and the turntable facilitates the sliding installation of multiple push rods. When the tops of the multiple push rods are inside the guide groove, the clamp at the bottom of the push rod is located inside the bottom of the fixed sleeve under the resistance of the return spring, and is in a retracted state, which facilitates the ejection of the clamped material and facilitates subsequent movement to the top of the material for retrieval. When the push rod slides out of the guide groove and into the bottom of the fixed plate, the push rod is pushed down, causing the push rod to drive the clamp to engage with the top of the material, thus clamping the center of the top of the T-iron. When the T-iron is tilted or placed in reverse, the bottom of the clamp cannot retrieve the T-iron, causing the T-iron to be ejected and retracted. The clamped material is conveyed to the loading workbench position by the rotation of the turntable. At this time, the push rod re-enters the guide groove and rises under the resistance of the return spring, thus unloading the material. This process is repeated to achieve material retrieval, transfer, and unloading. The operation is convenient and efficient. At the same time, it can be screened to keep the material in the same posture during loading, which is convenient for subsequent processing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, a T-iron feeding device includes a conveying mechanism 4, which includes a base 401. A fixed plate 402 is fixedly connected to the top of the base 401, and a turntable 403 is rotatably connected to the outer side of the top of the base 401. The turntable 403 is located at the bottom of the fixed plate 402. Multiple material picking mechanisms 5 are installed on the turntable 403. Each material picking mechanism 5 includes a push rod 502. Multiple push rods 502 are slidably connected to the edge of the turntable 403 in an annular and equidistant manner through a return spring 506. Each push rod 502 has a sleeve 507 installed at its bottom. The outer side of the bottom of the sleeve 507 is provided with a through groove 509. Multiple fixed sleeves 501 are vertically connected to the bottom of the turntable 403 in an annular and equidistant manner. The bottom of the multiple push rods 502 and the sleeves 507 are slidably connected to the inside of the fixed sleeves 501. A 180-degree guide groove 503 is provided at the bottom edge of the fixed plate 402. One end of the guide groove 503 is provided with a certain slope.

[0025] As a technical optimization of this utility model, the base 401 has a frustum-shaped structure. A drive component 404 is installed at the bottom of the base 401. The drive component 404 is connected to the bottom of the turntable 403, which facilitates the base 401 to support the turntable 403 and the fixed plate 402. At the same time, through the installation of the drive component 404, the turntable 403 can be driven and controlled in cooperation with the servo motor and gear set.

[0026] As a technical optimization of this utility model, the bottom edge of the jacket 507 is provided with multiple through grooves 509. The inner and outer edges of the bottom of the jacket 507 are arc-shaped. The opening of the through grooves 509 makes the bottom of the jacket 507 have good elasticity and facilitates the clamping and holding of materials, while also making it less prone to damage.

[0027] As a technical optimization of this utility model, multiple rubber blocks 511 are installed on the inner sidewall of the bottom of multiple jackets 507. The rubber blocks 511 have a trapezoidal structure. The installation of multiple rubber blocks 511 helps to increase the friction after clamping and prevent the material from slipping.

[0028] As a technical optimization of this utility model, a fixing ring 505 is fixedly connected to the bottom of the fixing sleeve 501. The area of ​​the fixing ring 505 is larger than the outer diameter of the fixing sleeve 501. By installing the fixing ring 505, the area of ​​the fixing sleeve 501 is increased, which facilitates the ejection of materials of different sizes.

[0029] As a technical optimization of this utility model, a slide rod 508 is slidably connected to the inner side of the bottom of the top rod 502 through a buffer spring 510. The top of the sleeve 507 is threadedly connected to the bottom of the slide rod 508. With the cooperation of the buffer spring 510, the slide rod 508 and the bottom of the top rod 502 have telescopic sliding, which helps the sleeve 507 to play a buffering role and prevents damage caused by contact with materials.

[0030] As a technical optimization of this utility model, a ball bearing 504 is rotatably connected at the top center of the top rod 502. The ball bearing 504 is in rolling connection with the guide groove 503 and the bottom of the fixed plate 402. The installation of the ball bearing 504 facilitates smooth transmission when the top rod 502 transitions from the guide groove 503 to the bottom of the fixed plate 402, reducing wear.

[0031] As a technical optimization of this utility model, a feeding component 1 is installed on the outside of the base 401, and a conveying plate 2 is installed on one side of the feeding component 1. The conveying plate 2 is located at one end of the guide groove 503. By installing the feeding component 1, a large amount of material can be stored and exported in sequence. The material is fed into the bottom of the top rod 502 through the conveying plate 2.

[0032] As a technical optimization of this utility model, a collection box 3 is installed at the bottom of the conveyor plate 2. One end of the collection box 3 extends to the outside of the turntable 403. The installation of the collection box 3 facilitates the collection of materials that have not been clamped and screened out, making it convenient for subsequent recycling.

[0033] In use, the base 401 is first installed in the designated position, and then the feeding assembly 1 with the conveyor plate 2 is placed stably, so that one end of the conveyor plate 2 is located at the bottom of the top rod 502. At the same time, a collection box 3 is installed at the bottom of the conveyor plate 2 to collect and store the screened material. The material inside the feeding assembly 1 is sequentially conveyed into the conveyor plate 2 and slides into the bottom of the top rod 502 through the conveyor plate 2. When the tops of multiple top rods 502 are located inside the guide groove 503, under the resistance of the return spring 506, the clamp 507 at the bottom of the top rod 502 is located inside the bottom of the fixed sleeve 501 and is in a retracted state. Through the installation of the drive assembly 404, under the control of the controller, the servo motor drives the gear set to control the gear set at the bottom of the turntable 403, thereby realizing that when the turntable 403 rotates at a certain speed, the ball bearings 504 on the top rod 502 slide out of the guide groove 503 and enter the fixed plate. When the material reaches the bottom of the 402, the push rod 502 is pushed down, causing the push rod 502 to drive the clamp 507 to engage with the top of the material. With the cooperation of the through groove 509, the clamp 507 has good elasticity and works with the rubber block 511 to clamp the center of the top of the T-iron. When the T-iron is tilted or placed upside down, the bottom of the clamp 507 cannot engage with the T-iron. The clamp 507 will retract under the action of the buffer spring 510. At the same time, when the turntable 403 rotates, it pushes the T-iron out of the collection box 3 for recycling. The clamped material is transported to the loading workbench position by the rotation of the turntable 403. At this time, the push rod 502 re-enters the guide groove 503. The push rod 502 rises under the resistance of the return spring 506 to unload the material. This process is repeated to pick up, transfer, and unload the material. The operation is convenient and efficient. It can also be used for screening to keep the material in the same posture during loading.
