[0002] In the manufacturing process of car speakers, the selection and transfer of materials such as cotton swabs directly affect the acoustic performance of the product. Different speaker models require specific specifications of cotton swab materials. Existing technologies commonly use material handling mechanisms and their driving devices. These devices achieve material adsorption and positioning correction through the cooperation of suction and correction components, but they do not involve color recognition functions for materials specifically for car speakers, making it difficult to adapt to the precise screening requirements of different types of cotton swabs.

[0003] Meanwhile, existing automated material handling equipment generally suffers from three major drawbacks when applied to selecting cotton swabs for vehicle speakers: First, its identification function is limited, mostly only able to locate the position and unable to distinguish material types based on features such as color. Second, the stability and accuracy of displacement drive are insufficient, and positioning deviations are easily caused by vibration or gaps in the fit during lateral and vertical movements. Third, the adjustment of the gripping angle and its adaptability to different materials are poor, making it difficult to meet the material handling needs of different assembly scenarios.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create an identification-based material selection device suitable for the manufacture of vehicle loudspeakers, making it more valuable for industrial applications. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] like Figure 1 A unique material selection device for vehicle speaker manufacturing, comprising a mounting bracket 1, is characterized by the inclusion of a lateral displacement drive device and a lateral displacement guide device mounted on the mounting bracket 1. During implementation, the lateral displacement drive device is a linear motor 8, the stator of which is fixed to the profile groove of the mounting bracket 1 by T-bolts, with a power range of 50-100W. The lateral displacement guide device includes a guide rail 4 and a slider 5. The guide rail 4 has a rectangular cross-section structure, preferably made of 45# steel with quenching treatment, and is fixed to the mounting bracket 1 by countersunk screws. The slider 5 is movably mounted on the guide rail 4. Simultaneously, a POM guide sleeve, 1-3mm thick, is nested inside the slider 5, with an interference fit to the inner wall of the slider 5. The guide rail 4 has grooves 6 distributed on it. The grooves 6 have a trapezoidal cross section with an upper base width of 3-5mm, a lower base width of 5-7mm, and a depth of 2-3mm. The slider 5 has corresponding connecting protrusions. The cross section of the connecting protrusions is adapted to the grooves 6 and is embedded in the grooves 6 to form an anti-detachment structure. The gap between the connecting protrusions and the grooves 6 is no more than 0.1mm, which further ensures the stability and accuracy of the lateral movement.

[0026] Meanwhile, the supporting device includes a support plate 7, which is made of 5-8mm thick 6061 aluminum alloy plate and milled to ensure a flatness of ≤0.05mm / m. The inner side of the support plate 7 is connected to the moving part 9 of the linear motor 8 and the slider 5 via connecting screws. The connecting screws are M6×20 socket head cap screws, 4-6 in number, evenly distributed along the edge of the support plate 7, ensuring that the support plate 7 moves laterally synchronously with the moving part 9 of the linear motor 8, and the slider 5 provides auxiliary guidance for the movement of the support plate 7. The outer side of the support plate 7 has a positioning base, which is a boss structure with a height of 10-15mm, integrally milled with the support plate 7. The vertical displacement drive device is connected to the positioning base, which provides the installation positioning reference for the vertical displacement drive device.

[0027] Furthermore, a vertical displacement drive device is used to realize the vertical movement of the material handling device. It includes a vertical guide rod 14, which is made of 45# steel with a chrome plating finish and has a diameter of 20-30mm. A servo motor 15 is mounted on one side of the vertical guide rod 14, and the housing of the servo motor 15 is fixed to the side wall of the vertical guide rod 14 with M5 bolts. During implementation, the drive rod of the servo motor 15 is a ball screw with a lead of 5-10mm. A guide block, made of aluminum alloy, is mounted on the drive rod, and has an internal sliding sleeve adapted to the vertical guide rod 14. The guide block and the vertical guide rod 14 slide against each other with a clearance of 0.05-0.1mm. When the servo motor 15 operates, the drive rod drives the guide block to move along the vertical guide rod 14, thereby driving the subsequent steering adjustment device 2 and the material handling device to move up and down synchronously.

[0028] To adjust the gripping angle of the material handling device, a steering adjustment device 2 is installed below the guide block, which includes a shock-absorbing base and a rotary cylinder. Specifically, the shock-absorbing base is connected to the guide block by M4 bolts. The shock-absorbing base can be made of rubber shock-absorbing pads with a thickness of 5-8mm, which can absorb the vibration generated during equipment operation. The rotary cylinder is installed below the shock-absorbing base, and the cylinder diameter can be 32-50mm. It is fixed to the shock-absorbing base by M8×30 ​​bolts, and 65Mn spring washers are fitted on the outside of the bolts to prevent the bolts from loosening when the equipment vibrates. At the same time, the rotation angle range of the rotary cylinder is 0-180 degrees. A flange connection is provided between the drive rod and the strip-shaped carrier plate body 10 of the material handling device, and the connection of the flange connection ensures the stable transmission of the rotation driving force.

[0029] According to a preferred embodiment of this utility model, the material handling device includes a strip-shaped carrier plate body 10. During manufacturing, the strip-shaped carrier plate body 10 can be made of 6061 aluminum alloy strips, with a length of 300-500mm, a width of 50-80mm, and a thickness of 8-12mm, and the surface is treated with natural anodizing. Simultaneously, the strip-shaped carrier plate body 10 has several weight-reducing holes 11 and mounting holes. The weight-reducing holes 11 can be elliptical holes, 50-80mm long and 10-15mm wide, evenly distributed along the length of the strip-shaped carrier plate body 10, used to reduce the overall weight. The mounting holes have a diameter of 12-16mm and an M10 internal thread on the inner wall for mounting and fixing the parallel opening and closing type pneumatic gripper 12. During installation, the tail end of the parallel opening and closing type pneumatic gripper 12 is connected to the mounting hole, and a locking block 13 is installed at the tail end. The locking block 13 is a rectangular metal block, which is connected to the tail end of the parallel opening and closing type pneumatic gripper 12 by an M4×10 hex socket screw. The rectangular metal block is attached to the upper surface of the strip-shaped carrier plate body 10 and fixed by an M5×12 countersunk screw. This achieves double fixation, ensuring that the pneumatic gripper is firmly installed. In addition, a contact block is installed on the inner wall of the claw of the parallel opening and closing type pneumatic gripper 12. The contact block includes a silicone block body (3-5mm thick). The silicone block body has several anti-slip grooves. The anti-slip grooves have a semi-circular or serrated cross-section and an adjacent spacing of 1-2mm, which can increase the friction with the material 16 and prevent the material 16 from slipping.

[0030] Furthermore, both the color sensing device 3 and the spatial sensing device (not shown in the figure) are mounted on the strip-shaped carrier plate body 10 of the material handling device to achieve the identification and positioning of the material 16. The color sensing device 3 includes a CCD sensor and a color recognition module. The CCD sensor can have a resolution of 12 megapixels and a frame rate of 30fps, while the color recognition module has a processing speed of 100ms / frame. During implementation, the color recognition module is connected to the CCD sensor via a ribbon cable. The CCD sensor collects the color information of the material 16 and transmits it to the color recognition module for processing, identifying whether the loaded cotton strip meets the processing requirements of the vehicle speaker. Different types of cotton strips are used for different models of vehicle speakers during processing. To facilitate differentiation, different types of cotton strips have different colors, making it easier for processing personnel and equipment to identify them. Simultaneously, the selected spatial sensing device is a laser sensor with a detection distance of 50-300mm and an accuracy of ±0.1mm, capable of detecting the spatial position of the material 16 and determining its specific coordinates. CCD and laser sensors are sequentially arranged along the length of the strip-shaped carrier plate 10. The detection direction of the CCD sensor forms a 45-90 degree angle with the gripping direction of the parallel opening and closing gripper 12 to ensure clear acquisition of the cotton strip's color information. Furthermore, both are electrically connected to an external controller (such as a PLC device) via 0.5mm² shielded wires for easy coordinated control.

[0031] In practical implementation, the positioning base of the bearing plate 7 is a boss structure with positioning pin holes. The top of the vertical guide rod 14 is fixed by the positioning pin engaging with the positioning pin hole, with a clearance of 0.015-0.035mm, ensuring accurate installation of the vertical guide rod 14. Simultaneously, a shock-absorbing adhesive layer, 1-2mm thick, preferably polyurethane, can be filled between the vertical guide rod 14 and the positioning base to further absorb vibrations generated during the operation of the vertical displacement drive device.

[0032] The working principle of this utility model is as follows: The external controller first receives the production instruction, then controls the laser sensor to detect the spatial position of the material 16, and controls the CCD sensor to collect the color information of the material 16 (such as cotton strips) and identify it by the color recognition module. If the material 16 meets the requirements, the external controller controls the linear motor 8 to work, driving the carrier plate 7 to move laterally along the guide rail 4 to above the material 16. Then, the external controller controls the servo motor 15 to work, driving the guide block to move downward along the vertical guide rod 14, so that the parallel opening and closing type air gripper 12 of the picking device approaches the material 16. At the same time, if it is necessary to adjust the gripping angle, the external controller controls the rotary cylinder to work, driving the strip-shaped carrier plate body 10 to rotate to a suitable angle, and finally controls the parallel opening and closing type air gripper 12 to close, gripping the material 16 through the silicone block body of the contact block and the anti-slip strip groove. After the gripping is completed, the servo motor 15 drives the guide block to move upward, the linear motor 8 drives the carrier plate 7 to move to the designated position, and the parallel opening and closing type air gripper 12 opens, completing the transfer of the material 16 and realizing the automated identification and selection of materials in the manufacturing process of vehicle speakers.

[0034] 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.
