Description

Technical Field

[0001] This utility model relates to a material handling device, and more particularly to a material handling device suitable for processing sound-generating units. Background Technology

[0002] In the current speaker manufacturing process, multiple components are used. To avoid resonance, foam gaskets are placed in the sound-producing unit. Traditionally, these are joined manually by pressing, resulting in low processing efficiency. Currently, automated processing equipment is used. However, existing equipment uses multiple independent stations and feeding lines to complete feeding, picking, and joining the foam gaskets, occupying a significant amount of processing space. Furthermore, each station needs to wait independently, failing to improve processing efficiency. Additionally, regardless of whether a gripping or adsorption method is used, only simple handling and transfer are possible; it's impossible to join the foam gaskets after picking up the materials.

[0003] For example, the prior art CN106904425B discloses a three-station vertical material handling device, which achieves electrode plate transfer by moving the suction component in the front-back direction and uses vertical suction action to improve stability. However, it is only suitable for electrode plate transfer between a single station and does not involve multi-station collaborative control in the horizontal and vertical directions. It cannot meet the requirements of continuous switching of multiple processes in the processing of sound-generating units, and the adjustment accuracy of the suction component is insufficient.

[0004] Meanwhile, the existing technology CN209161030U provides a negative pressure adsorption conveying device, which uses a negative pressure cylinder and a pressure regulating plate to adjust the vacuum level and controls the adsorption force through a knob. However, during use, it relies solely on adsorption by a single cylinder and lacks a graded adsorption control mechanism. When adsorbing precision sound-producing units, the workpiece is prone to fall off due to instantaneous pressure fluctuations, and changing models requires adjusting the knob, making the operation cumbersome.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a material handling device suitable for the processing of sound units, so as to make it more industrially valuable. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a material handling device suitable for the processing of sound-generating units.

[0007] This utility model discloses a material handling device suitable for processing sound-generating units, comprising a device support, wherein: a lateral displacement adjustment device is installed on the device support, and a plurality of station material handling devices are installed on the lateral displacement adjustment device; each station material handling device includes a bearing device connected to the lateral displacement adjustment device, and a longitudinal displacement adjustment device is installed on the bearing device; a mounting bracket is connected to the longitudinal displacement adjustment device; a docking assembly and a negative pressure device are mounted on the lower end of the mounting bracket via an adjusting wing plate; the negative pressure device is conductively connected to the docking assembly; the docking assembly includes a suction head body, and a docking flange structure is provided at the upper end of the suction head body; the docking flange structure is connected to the adjusting wing plate; the suction head body is connected to the negative pressure device via a conduit; and contact sealing rings are distributed at the lower end of the suction head body.

The drive end of the servo motor is connected to a longitudinal slider, and a bearing bracket is connected to the longitudinal slider. A mounting bracket is connected to the lower part of the bearing bracket via a guide rod.

[0012] Furthermore, in the aforementioned material handling equipment suitable for processing sound-generating units, both the supporting bracket and the mounting bracket are L-shaped brackets, and reinforcing plates are installed on both sides of the L-shaped brackets.

[0013] Furthermore, in the aforementioned material handling equipment suitable for processing sound-generating units, a fine-tuning device is distributed below the mounting bracket. The fine-tuning device includes parallel guide rails, which are connected to adjusting wing plates via locking screws. Negative pressure devices are installed on both sides of the adjusting wing plates, and a docking assembly is installed below the adjusting wing plates.

[0014] Furthermore, in the aforementioned material handling equipment suitable for processing sound-generating units, the negative pressure device includes a main negative pressure cylinder and a secondary negative pressure cylinder.

[0015] Furthermore, in the aforementioned material handling equipment suitable for processing sound-generating units, the suction head body has a quick-change carrier for the material handling module adsorbed on it.

[0016] By means of the above solution, this utility model has at least the following advantages:

[0017] 1. Enables multi-station collaborative operation. Through the coordinated control of the lateral and longitudinal displacement adjustment devices, this equipment can achieve rapid switching between multiple stations, meeting the material handling and loading requirements of different processing steps, significantly reducing manual secondary handling time and improving processing efficiency. Furthermore, the multi-station parallel operation design optimizes space utilization and solves the problem of low efficiency in traditional single-station equipment.

[0018] 2.

[0020] 4. Employing a staged adsorption control system using a main negative pressure cylinder and an auxiliary negative pressure cylinder, combined with a contact sealing ring beneath the suction head, this equipment achieves airtight contact during adsorption, ensuring stable gripping of the sound-generating unit workpiece. The main cylinder provides continuous adsorption force, while the auxiliary cylinder enhances instantaneous adsorption intensity during docking, effectively preventing the risk of workpiece detachment.

[0021] 5. Through the design of the quick-change carrier of the material handling module and its flange docking with the suction head body, this equipment can quickly change to a suitable carrier for different models of sound-generating units, significantly improving equipment compatibility. The matching design of the contoured groove structure with the workpiece shape further optimizes positioning accuracy and shortens changeover and debugging time.

[0022] 6. Through the longitudinal displacement adjustment device driven by the servo motor and the guide rod connection structure, this equipment can achieve precise vertical movement of the mounting bracket, and complete the switching between bottom feeding belt material picking and top station material unloading within a limited space, solving the layout difficulties caused by the height limitation of traditional equipment.

[0023] 7. The equipment can be quickly fixed to the processing machine using the locking holes and positioning bolts at the bottom of the paired mounting frames, leaving space for the bottom feeding line. The modular design simplifies the equipment assembly and disassembly process, facilitating subsequent maintenance and functional expansion.

[0024] 8. The sound unit and the sponge gasket can be combined during the material handling process, which improves assembly efficiency.

[0029] Detailed Implementation

[0030] The specific embodiments of this utility model will be described in further 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 its scope.

[0031] like Figures 1 to 2The material handling equipment suitable for sound unit processing includes a support frame, which is unique in that: a lateral displacement adjustment device 1 is installed on the support frame, and several workstation material handling devices 2 are installed on the lateral displacement adjustment device 1. This allows the workstation material handling devices 2 to be positioned at different workstations through the control of the lateral displacement adjustment device 1, facilitating material handling and unloading between different workstations and processing steps without requiring secondary manual handling. Simultaneously, the workstation material handling devices 2 include a supporting device connected to the lateral displacement adjustment device 1, and the supporting device is equipped with a longitudinal displacement adjustment device. This allows for adjustment of the longitudinal height, facilitating longitudinal displacement switching between bottom feeding belt material handling and upper workstation unloading, reducing the occupation of lateral space and facilitating the implementation of a multi-workstation layout. Furthermore, a mounting bracket 3 is connected to the longitudinal displacement adjustment device, and a docking component and a negative pressure device are mounted on the lower end of the mounting bracket 3 via an adjusting wing plate 4. The negative pressure device is electrically connected to the docking component. Thus, relying on the coordinated control of the negative pressure device, the adsorption control of the docking component is achieved. For ease of implementation, the docking assembly includes a suction head body 5, with a docking flange structure at its upper end. This flange structure is connected to the adjusting wing plate 4, ensuring stable and quick-change docking. The suction head body 5 is connected to the negative pressure device via a conduit, and contact sealing rings 6 are distributed at its lower end. This ensures airtightness of the contact surface during negative pressure adsorption.

[0032] According to a preferred embodiment of this utility model, to facilitate docking with the reserved machine base of the processing equipment, the equipment support includes paired mounting frames 7. Several locking holes are distributed below the mounting frames 7, which are fixed to the machine base by positioning bolts. Simultaneously, guide bases 8 are connected between the mounting frames 7, and the lateral displacement adjustment device 1 is mounted on the guide bases 8. This allows for the lifting and installation of the lateral displacement adjustment device 1, reserving space for the bottom feeding line of the processing equipment. Furthermore, considering ease of implementation, the lateral displacement adjustment device 1 is a linear motor, and the drive slider of the linear motor is connected to the supporting device. This satisfies the need for high-speed, high-precision lateral displacement adjustment.

[0033] Furthermore, the supporting device includes a longitudinal support plate 9, which facilitates the smooth installation of other components. Simultaneously, a translational support plate 10 is installed on the upper rear side of the longitudinal support plate 9, and the translational support plate 10 is connected to the drive slider of a linear motor. Thus, under the action of the drive slider, the translational support plate 10 moves horizontally. Moreover, several guide sliders 11 are installed on the lower rear side of the longitudinal support plate 9, and linear slide rails 12 are installed at corresponding positions on the equipment bracket. The guide sliders 11 and the linear slide rails 12 are in sliding engagement. Preferably, two parallel linear slide rails 12 can be used. This ensures the smooth movement of the longitudinal support plate 9, preventing workpiece tilting or falling due to vibration during subsequent workpiece loading.

[0034] In practical implementation, the longitudinal displacement adjustment device includes a servo motor 13 mounted on the upper end of the bearing device. The drive end of the servo motor 13 is connected to a longitudinal slider 14, and a bearing bracket 15 is connected to the longitudinal slider 14. A mounting bracket 3 is connected to the lower part of the bearing bracket 15 via a guide rod. Thus, relying on the servo motor 13, the longitudinal displacement of the mounting bracket 3 can be adjusted to accommodate switching between different horizontal heights, such as in the feeding line and processing station, facilitating material handling and feeding docking. Simultaneously, to ensure load-bearing stability, both the bearing bracket 15 and the mounting bracket 3 are L-shaped brackets, with reinforcing plates installed on both sides of the L-shaped brackets.

[0035] Meanwhile, to eliminate potential tolerances during assembly, a fine-tuning device is distributed below the mounting bracket 3. Specifically, the fine-tuning device includes parallel guide rails 18, which are connected to adjusting wing plates 4 via locking screws. Negative pressure devices are installed on both sides of the adjusting wing plates 4, and a docking assembly is installed below the adjusting wing plates 4. In this way, guided by the guide rails 18, the adjusting wing plates 4 can be adjusted appropriately forward and backward, ensuring that the negative pressure devices are precisely aligned with the workpiece to be picked up when they move downward. Of course, depending on different preset needs, the guide rails 18 can be arranged in pairs, or other guiding methods such as grooves can be used, which will not be elaborated here.

[0036] Furthermore, to meet diverse material loading needs and achieve coordinated control of continuous and instantaneous adsorption, the negative pressure device includes a main negative pressure cylinder 16 and a secondary negative pressure cylinder 17. Simultaneously, to match the shape of the workpiece, such as the sound-generating unit, and achieve better top adsorption positioning, a quick-change carrier 19 for the material handling module is attached to the suction head body 5. Thus, the quick-change carrier 19 has a contoured groove structure below it that matches the shape of the sound-generating unit, allowing for a precise adsorption. During this period, the main negative pressure cylinder 16 operates first, achieving long-term adsorption positioning of the quick-change carrier 19. When the quick-change carrier 19 docks with the corresponding workpiece, the secondary negative pressure cylinder 17 intervenes, achieving secondary adsorption positioning of the workpiece.

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

[0038] Based on the model and upper shape of the current sound-generating unit, select the corresponding quick-change carrier 19 for the material picking module and place it at the corresponding position below the suction head body 5. Then, activate the main negative pressure cylinder 16 to position the quick-change carrier 19 in a suction-engaged state.

[0039] Then, the lateral displacement adjustment device 1 moves the workstation material handling device 2 to above the sound-generating unit. Next, the longitudinal displacement adjustment device moves the mounting bracket 3 downward, ultimately docking the quick-change carrier 19 of the material handling module with the sound-generating unit. At this point, the secondary negative pressure cylinder 17 starts working, causing the suction head body 5 to work in conjunction with the quick-change carrier 19 of the material handling module to adsorb the sound-generating unit. Then, the longitudinal displacement adjustment device moves the mounting bracket 3 back up, preparing for subsequent installation.

[0040] Next, the lateral displacement adjusting device 1 moves the station material picking device 2 to the sponge gasket feeding station. The longitudinal displacement adjusting device moves the mounting bracket 3 down again, allowing the lower end of the sound-generating unit to be installed and joined with the corresponding sponge gasket. Then, the longitudinal displacement adjusting device resets. At the same time, the lateral displacement adjusting device 1 moves the station material picking device 2 to the unloading area. The longitudinal displacement adjusting device moves down a third time, allowing the joined sound-generating unit to reach the discharge feeding belt. Then, the auxiliary negative pressure cylinder 17 stops operating, completing the release of the sound-generating unit.

[0041] Finally, repeat the above process to achieve continuous processing.

[0042] Furthermore, the indicated orientations or positional relationships described in this utility model are all based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing 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. Therefore, they should not be construed as limitations on this utility model. The above descriptions are merely preferred embodiments of this utility model and are not intended to limit this 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 this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
