Description

Technical Field

[0001] This utility model relates to a receiving device, and more particularly to a receiving device for a quiet room suitable for processing sound-generating devices. Background Technology

[0002] In the field of electroacoustic device manufacturing, sound-generating devices (such as loudspeakers and miniature receivers) need to undergo acoustic testing in a soundproof room to avoid environmental noise interference. After testing, the workpieces need to be transferred from the soundproof room to the subsequent assembly line. However, the enclosed nature of the soundproof room leads to low material transfer efficiency and easy introduction of external noise. Existing technologies mainly address this problem through the following two methods:

[0003] 1. Manual material handling method.

[0004] Operators manually retrieve the sound-generating device through a pre-set material retrieval window in the soundproof room. This method poses a risk of noise leakage and is inefficient, easily causing workpiece collision damage. For example, prior art CN202075036U discloses an automatic transmission device for assisting soundproof room detection, which features a soundproof room window paired with a belt conveyor. However, this device relies on inductive switches to control the opening and closing of the window, resulting in insufficient workpiece positioning accuracy and a risk of pinching or positioning misalignment.

[0005] 2. Automatic material handling by robotic arm.

[0006] Industrial robotic arms can directly pick up workpieces from a quiet room. While such equipment reduces human intervention, it has two major limitations: poor structural compatibility, and the need for customized robotic arm grippers for different models of sound-generating devices. For example, existing technology CN220007807U discloses an industrial material handling robotic arm that uses limiting grooves and limiting posts to fix the workpiece, but its carrier plate cannot be adapted to sound-generating devices with raised contacts (such as terminals or conductive pins) on the bottom, resulting in unstable placement or contact damage. Furthermore, most robotic arms lack a workpiece-in-place detection mechanism, making it impossible to accurately sense the placement status of miniature sound-generating devices (such as whether they are centered or whether the contacts are aligned).

[0007] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a silent room receiving device suitable for the processing of sound-generating devices. It can be connected to a silent room to realize automatic material receiving and minimize noise interference. Utility Model Content

[0008] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a silent room receiving device suitable for the processing of sound-generating devices.

[0009] This utility model discloses a soundproof room receiving device for processing sound-generating devices, comprising a mounting base, wherein: a guide drive device is installed at the rear end of the mounting base, a guide mechanism is installed on the mounting base, a carrier plate device is movably connected to the guide mechanism, the carrier plate device is connected to the guide drive device, a main sensing device is installed on the mounting base, a secondary sensing device is installed on the front side of the mounting base, the carrier plate device includes a carrier plate body, a limit groove is formed on the carrier plate body, a plurality of limit posts are distributed along the edge of the limit groove, auxiliary baffles are mirror-distributed on both sides of the carrier plate body, the lower part of the carrier plate body is movably connected to the guide mechanism, and a docking adjustment component is also installed on the carrier plate body, the docking adjustment component is connected to the guide drive device.

[0010] Furthermore, in the aforementioned soundproof room receiving equipment suitable for processing sound-generating devices, the guiding mechanism is a linear slide rail mirror-connected to the inner side below the mounting base, and a slider is movably connected to the linear slide rail. The carrier plate body and the corresponding slider are connected by screws.

[0011] Furthermore, in the aforementioned soundproof room receiving equipment suitable for processing sound-generating devices, the main sensing device includes an adjustment plate installed on the front side of the mounting base.

[0012] Furthermore, in the aforementioned soundproof room receiving equipment for processing sound-generating devices, the auxiliary sensing device includes a lifting mounting plate, the upper end of which is folded into a mounting platform, and an auxiliary photoelectric sensor is mounted on the mounting platform.

[0013] Furthermore, in the aforementioned soundproof room receiving equipment suitable for processing sound-generating devices, a reserved through hole is provided in the limiting groove.

[0014] Furthermore, in the aforementioned soundproof room receiving equipment suitable for processing sound-generating devices, the guide drive device is a cylinder, and the drive end of the cylinder is connected to the docking adjustment assembly via a guide rod.

[0015] Furthermore, in the aforementioned soundproof room receiving equipment for processing sound-generating devices, the docking adjustment assembly includes a docking block mounted on the carrier plate body, an adjusting screw horizontally mounted on the docking block, and the adjusting screw connected to a guide drive device.

[0016] Furthermore, in the aforementioned soundproof room receiving equipment for processing sound-generating devices, the mounting base includes a mounting frame, and a docking plate extends forward from the lower end of the mounting frame, with the guiding mechanism installed inside the docking plate.

[0017] Furthermore, in the aforementioned soundproof room receiving equipment suitable for processing sound-generating devices, the docking plate is provided with several positioning holes.

[0018] Furthermore, in the aforementioned soundproof room receiving equipment suitable for processing sound-generating devices, the auxiliary baffle is provided with several weight-reducing holes.

[0019] By means of the above solution, this utility model has at least the following advantages:

[0020] 1. By cooperating with the guide drive device and the carrier plate device, the sound-generating device can be efficiently switched between the feeding station and the picking station, effectively meeting the coordination and docking needs of picking up materials from the soundproof room and sending them to the subsequent assembly station, thus improving production efficiency.

[0024] 5. The design of the entire equipment realizes the automated transmission of the sound-generating device from the soundproof room to the subsequent assembly station, reducing manual intervention, lowering labor intensity, and improving the level of automation and overall production quality.

[0025] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. Attached Figure Description

[0027] The meanings of the labels in the figures are as follows.

[0028] Detailed Implementation

[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] like Figure 1 A soundproof room receiving device for processing sound-generating devices includes a mounting base 1. Its unique feature is that a guide drive device (not shown in the figure) is installed at the rear end of the mounting base 1, and a guide mechanism is installed on the mounting base 1. A carrier plate device is movably connected to the guide mechanism, and the carrier plate device is connected to the guide drive device. Thus, driven by the drive device, the carrier plate device can move along the guide mechanism, switching between the feeding station and the picking station, meeting the coordinated docking needs of picking up materials from the soundproof room and sending them to the subsequent assembly station. Simultaneously, to promptly sense the placement status of the sound-generating device during subsequent receiving and feeding, facilitating operational feedback from the feeding and picking equipment, this invention includes a main sensing device on the mounting base 1 and a secondary sensing device on the front side of the mounting base 1. This allows for sensory feedback through mutual cooperation between the two. During implementation, considering the need for stable transfer of the sound-generating device, the carrier plate device includes a carrier plate body 2, with a limiting groove 3 on the carrier plate body 2, and several limiting posts 4 distributed along the edge of the limiting groove 3. In this way, the shape of the limiting groove 3 matches the shape of the bottom of the sound-generating device, enabling placement and positioning. Furthermore, the limiting post 4 can be inserted into the mounting guide hole at the bottom of the sound-generating device for auxiliary locking. During subsequent movement of the carrier plate body 2, improper displacement of the sound-generating device will not occur, facilitating smooth subsequent gripping. Auxiliary baffles 5 can also be mirror-distributed on both sides of the carrier plate body 2. This allows for auxiliary limiting at the side ends, especially for sound-generating devices with a center of gravity offset, providing side-end support and preventing improper shaking during transportation. During use, considering the smooth displacement of the carrier plate body 2, its lower part is movably connected to the guide mechanism. Moreover, a docking adjustment component connected to the guide drive device is also installed on the carrier plate body 2. This allows adjustment of the actual position of the carrier plate body 2 during the push-out stage and at the feeding station according to the actual working stroke of the feeding equipment, facilitating precise feeding docking. Of course, to effectively reduce the load on the guide drive device, several weight-reducing holes 21 can be opened on the auxiliary baffles 5. This reduces the overall weight while meeting the load-bearing strength requirements.

[0031] In a preferred embodiment of this invention, the guiding mechanism is a linear slide rail 6 mirror-connected to the inner side below the mounting base 1, used for guiding linear motion. Simultaneously, a slider 7 is movably connected to the linear slide rail 6, and the slider 7 corresponding to the carrier plate body 2 is connected by screws. Thus, the slider 7, in conjunction with the guiding drive device, enables the movement of the carrier plate body 2. During use, quick-release screws 8 can be used to facilitate the selection and installation of the corresponding carrier plate body 2 according to the model of the current sound-generating device during debugging.

[0032] Furthermore, the main sensing device includes an adjustment plate 9 mounted on the front of the mounting base 1. The adjustment plate 9 has several mirror-distributed elongated holes 10, which are connected to a mounting plate 11 via adjusting screws. This allows the mounting height of the mounting plate 11 to be adjusted according to the actual placement of the sound-generating device. Simultaneously, the mounting plate 11 is L-shaped, and a main photoelectric sensor 12 is connected to it. This ensures stable placement of the photoelectric sensor, enabling it to effectively detect the insertion and removal of the sound-generating device during operation.

[0033] Meanwhile, to better implement this utility model, the auxiliary sensing device includes a lifting mounting plate 13, the upper end of which is folded to form a mounting platform, on which an auxiliary photoelectric sensor 14 is mounted. This allows the mounting platform to be fixed to the working area of ​​the feeding equipment according to the actual routing requirements of the processing equipment. Furthermore, both the main and auxiliary photoelectric sensors can be through-beam photoelectric sensors, which can better sense the placement status of the sound-emitting device on the carrier plate, thereby improving sensing accuracy. It should be noted that... Figure 1 The straight line in the diagram represents two through-beam photoelectric sensors performing through-beam sensing; in actual implementation, an invisible beam of light can be used.

[0034] In practical implementation, considering that some sound-generating devices have outwardly protruding wiring protrusions and conductive contacts at the bottom, a pre-drilled through-hole 15 can be made in the limiting groove 3 to ensure stable placement within it. This way, after placement, the outwardly protruding portion is precisely contained by the pre-drilled through-hole 15, preventing the wiring protrusions and conductive contacts from being squeezed. Simultaneously, it prevents the sound-generating device from tilting significantly on the carrier plate 2 due to unevenness at the bottom, avoiding large displacements during material feeding and docking, and ensuring smooth docking of the material handling equipment.

[0035] During implementation, to provide convenient displacement control, a cylinder is used as the guide drive device, and the drive end of the cylinder is connected to the docking adjustment assembly via a guide rod 18. Of course, depending on the layout requirements of the supporting equipment, an electric cylinder or linear motor can also be selected. Simultaneously, to facilitate convenient adjustment of the actual push-out limit position according to the actual drive stroke of different guide drive devices, the docking adjustment assembly includes a docking block 16 mounted on the carrier plate body 2. Furthermore, an adjusting screw 17 is horizontally mounted on the docking block 16, and the adjusting screw 17 is connected to the guide rod 18 of the guide drive device. Thus, during actual debugging, simply rotating the screw adjusts the extension distance of the guide rod 18, thereby controlling the actual distance of the carrier plate body 2 in the push-out state. After adjustment, positioning can be achieved by adding an external locking block or using a screw with a self-locking mechanism to prevent the screw from loosening during use.

[0036] Furthermore, to achieve a suitable clearance without affecting the displacement of the carrier plate 2, the mounting base 1 includes a mounting frame, which provides clearance similar to a gantry frame. Simultaneously, a docking plate 19 extends forward from the lower end of the mounting frame, and the linear guide rail 6 of the guiding mechanism is installed inside the docking plate 19. This provides excellent linear guidance and ensures the rigidity of the linear guide rail 6, preventing deformation during use. Moreover, considering compatibility with the sound-generating device manufacturing equipment, several positioning holes 20 are provided on the docking plate 19. This allows the mounting base 1 to be fixed to the reserved installation area of ​​the sound-generating device manufacturing equipment using locking bolts and other positioning components.

[0037] The working principle of this utility model is as follows:

[0038] After the sound-generating device completes its testing and processing in the soundproof room, this invention uses a guide drive device to push the carrier plate 2 into the pre-set material inlet of the soundproof room, allowing it to reach the feeding station. Then, the transport device in the soundproof room places the sound-generating device into the carrier plate 2. During this process, the protruding part at the bottom of the sound-generating device is accommodated by the pre-reserved through hole 15, the overall contour of the bottom mates with the limiting groove 3, and the mounting guide hole at the bottom engages with the limiting post 4 for positioning. Simultaneously, the auxiliary sensing device notifies the corresponding control system of the equipment to complete the receiving and loading process.

[0039] Next, the guide drive device controls the carrier plate body 2 to reset, allowing the sound-emitting device to pass through the material handling port and reach the material handling station. At this time, the main sensing device detects that the sound-emitting device is in a ready-to-use state and notifies the corresponding material handling equipment to retrieve the sound-emitting device.

[0040] Then, proceed with the assembly of the current sound-generating device and the testing of the soundproof room, repeating the process cyclically.

[0041] During use, this invention only requires a small modification to the material inlet on one side of the soundproof room to reduce noise intrusion into the soundproof room while allowing the sound-generating device to discharge directly. Of course, to improve this effect, a noise-reducing channel can be added between the soundproof room and the subsequent material handling equipment. The sound-generating device can still be smoothly transferred thanks to the advancement of the carrier plate 2. Furthermore, the soundproof room is in a non-operating state during actual material handling, so normal implementation will not affect the normal operation of the subsequent soundproof room.

[0042] Furthermore, the directions or positional relationships described in this utility model are based on the directions or positional relationships shown in the accompanying drawings. They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
