Description

Technical Field

[0001] This utility model relates to the field of headphone manufacturing technology, specifically to an automatic headphone sorting device. Background Technology

[0002] Headphones are a pair of transducers that receive electrical signals from a media player or receiver and convert them into sound waves audible to the human ear using sound-producing units placed close to the ears. Headphones can prevent disturbing others and isolate ambient noise, avoiding interference from the surrounding environment. Traditional headphones are generally used in products such as mobile phones, portable music players, portable game consoles, and digital audio players, connecting to these products via wires. However, in recent years, with the rapid development of technology, headphones that transmit audio signals wirelessly have gradually become more common. The headphone manufacturing process involves assembling components such as PCBA, battery, sound-producing units, and shell. After assembly, multiple tests are required, such as functional tests, acoustic tests, and radio frequency tests. Based on the test results, the headphone's performance is calibrated to determine whether it meets design standards. Because it's difficult to maintain 100% consistency in hardware quality, and minor errors may occur during manufacturing (such as slight misalignment of the speaker unit or minor dimensional errors in the casing), it's inevitable that products will ultimately differ in performance. To avoid impacting the final user experience, headphones need to be categorized based on test results—that is, tiered—and headphones with similar performance should be grouped together. Therefore, a device capable of tiering headphones is needed. Utility Model Content

[0020] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] Reference Figures 1 to 4 The present invention provides an automatic headphone sorting device, comprising: a housing 1, a conveying mechanism 2, a transfer mechanism 3, and a material handling mechanism 4.

[0022] The chassis 1 is provided with several grading areas, each containing a tray for temporarily storing headphones during the grading process. In this embodiment, three grading areas are arranged in a row, each containing three trays. The number of grading areas is not specifically limited; it can be set according to production needs. Each grading area on the chassis 1 is provided with several limiting members 11 for tray positioning. These limiting members 11 surround and form a space to accommodate the tray. Specifically, the tray is rectangular, hence four limiting members 11 are provided, each limiting the position of the tray from its four sides. The trays in the grading areas are used for temporary headphone storage. When grading the headphones in the trays on the conveyor mechanism 2, in order to place headphones with similar performance into the same tray (e.g., headphones of the same grade into the same tray), a portion of the headphones from one tray on the conveyor mechanism 2 needs to be transferred to the trays in the grading areas to free up space, making it easier to place headphones from other trays on the conveyor mechanism 2 into the freed-up space.

[0023] A conveying mechanism 2 is located on one side of the chassis 1. The conveying mechanism 2 is used to convey trays containing headphones. The conveying mechanism 2 includes a conveying support frame 21, a conveyor belt 22 mounted on the conveying support frame 21, and several tray positioning components 23 mounted on the conveying support frame 21 for positioning the trays. The conveyor belt 22 of the conveying mechanism 2 connects with other processes in the headphone production line. The infeed end of the conveyor belt 22 receives trays from the previous process (e.g., from the testing process), while the discharge end of the conveyor belt 22 connects to the next process, forming a complete and continuous production flow chain. This improves the smoothness of the connection between different processes, enables online sorting of headphones, and improves overall production efficiency.

[0024] A transfer mechanism 3 is mounted on the housing 1, and the transfer mechanism 3 transfers headphones between the conveyor mechanism 2 and the sorting area. Specifically, the transfer mechanism 3 is used to transfer headphones between the trays on the conveyor belt 22 and the trays in the sorting area.

[0025] The transfer mechanism 3 includes an X-axis moving module 31 mounted on the chassis 1, a Y-axis moving module 32 connected to the X-axis moving module 31, and a Z-axis moving module 33 connected to the Y-axis moving module 32. The material handling mechanism 4 is connected to the Z-axis moving module 33. Each of the X-axis moving module 31, Y-axis moving module 32, and Z-axis moving module 33 includes a linear module 311, a slide 312 connected to the linear module 311, and a moving drive component 313 for driving the linear module 311. With the cooperation of the X-axis moving module 31, Y-axis moving module 32, and Z-axis moving module 33, the material handling mechanism 4 can move flexibly within the stroke range of the transfer mechanism 3.

[0026] The transfer mechanism 3 further includes an X-axis driven module 34 arranged parallel to the X-axis moving module 31. The X-axis driven module 34 is connected to the X-axis moving module 31 via a drive shaft 35. One end of the Y-axis moving module 32 is connected to the X-axis moving module 31, and the other end of the Y-axis moving module 32 is connected to the X-axis driven module 34. The X-axis driven module 34 also has a linear module 311. The driving component of the X-axis moving module 31 is connected to one end of the drive shaft 35 via a transmission assembly (such as a gear set), and the other end of the drive shaft 35 is connected to the linear module 311 of the X-axis driven module 34 via a transmission assembly. When the X-axis moving module 31 drives the Y-axis moving module 32 to move, the X-axis driven module 34 can be driven simultaneously to ensure the stability of the movement.

[0027] The material handling mechanism 4 is connected to the transfer mechanism 3, and is used to pick up and place headphones. The transfer mechanism 3 controls the material handling mechanism 4 to move between the conveyor belt 22 and the sorting area to pick up and place headphones. Figure 4 As shown, the material handling mechanism 4 includes a lifting frame 41 connected to the transfer mechanism 3 and a plurality of material handling components 42 disposed on the lifting frame 41. Each material handling component 42 includes a lifting drive 421 connected to the lifting frame 41, a gripper cylinder 422 connected to the output end of the lifting drive 421, and a material handling component 423 connected to the output end of the gripper cylinder 422. The lifting drive 421 of the material handling component 42 can be a cylinder, and each gripper cylinder 422 moves downwards individually. In this embodiment, four material handling components 42 are provided, with each pair of material handling components 42 forming a group. Two earphones can be held simultaneously at one time, and two groups of material handling components 42 can hold four earphones.

[0028] like Figure 3 As shown, the tray positioning assembly 23 includes a positioning drive 231 mounted on the conveyor support frame 21, a pressure block 232 connected to the output end of the positioning drive 231, a blocking drive 233 mounted on the conveyor support frame 21, and a blocking block 234 connected to the output end of the blocking drive 233. The positioning drive 231 is located above the conveyor belt 22, and its driving direction is perpendicular to the conveying direction of the conveyor belt 22. Figure 1 From the perspective of the positioning drive 231, the pressure block 232 moves rearward to press the material tray from the side, preventing the tray from moving. The blocking block 234 has a blocking part that matches the corner shape of the material tray. The blocking drive 233 drives the blocking part to move above the conveyor belt 22. When the material tray flowing on the conveyor belt 22 turns, it enters the blocking part, and the material tray is stopped from moving further. At this time, the positioning drive 231 drives the pressure block 232 to press the material tray, thus achieving the positioning of the material tray.

[0029] The tray positioning assembly 23 further includes two guide brackets 51235 disposed on the conveyor support frame 21. The two guide brackets 51235 are symmetrically arranged, and there is a gap between the two guide brackets 51235 for the tray to pass through. In this embodiment, the positioning drive 231 is disposed at one of the guide brackets 51235. The guide bracket 51235 is provided with a hole for the pressure block 232 to pass through. The pressure block 232 can press the tray against the guide bracket 51235 on the other side to form a clamping state, thereby realizing the positioning of the tray. In this embodiment, both the positioning drive 231 and the blocking drive 233 are cylinders. In this embodiment, there are two tray positioning assemblies 23, one near the front end of the conveyor belt 22 and the other near the rear end of the conveyor belt 22. In addition, a blocking assembly is also required before the front tray positioning assembly 23 to prevent the subsequent trays from continuing to move during the sorting process.

[0030] The tray positioning assembly 23 also includes a sensor 236 mounted on the conveyor support frame 21 for sensing the tray, and a card reader 237 mounted on the conveyor support frame 21. The sensor 236 can be a fiber optic sensor 236, a through-beam sensor 236, or similar types, and is mainly used to sense whether the tray is in position. A chip is pre-installed in the tray, recording information about the tray (including tray number, number of earphones in the tray, earphone performance level, etc.). The card reader 237 reads the tray information via near-field communication, facilitating the classification of earphones.

[0031] An industrial control component 5 is provided on the front side of the conveyor support frame 21. The industrial control component 5 includes a bracket 51, an industrial control box 52 mounted on the bracket 51, and a display 53 mounted on the bracket 51. The industrial control box 52 contains an industrial computer, which is connected to various mechanisms and used to control the actions of each mechanism.

[0032] In actual operation, the conveying mechanism 2 receives a tray containing headphones from the previous process. The headphones in the tray have been tested and marked with their performance grades. When the tray reaches the tray positioning component 23, the tray positioning component 23 positions the tray to prevent it from moving further. In this embodiment, there are two tray positioning components 23. The tray positioning component 23 at the rear of the conveying direction first positions tray 1, and the tray positioning component 23 at the front of the conveying direction then positions tray 2. In this embodiment, the headphones are divided into three grades: A, B, and C. Both trays 1 and 2 contain headphones of all three grades. In this embodiment, the grade requirement is to place grade A and grade B headphones on the same tray, and grade B and grade C headphones on the same tray. The transfer mechanism 3 drives the picking mechanism 4 to move to tray 1 on the conveyor belt 22, removes all grade C headphones from tray 1 and transfers them to a tray in one of the graded areas. Then, the grade A headphones on tray 2 are transferred to an empty space on tray 1 (if tray 1 is empty). If there is insufficient space, the A-grade headphones can be transferred to another tray in the sorting area, waiting for a later tray to have space before transferring them. Then, the C-grade headphones can be transferred from the sorting area to an empty space in tray 2 (if there is insufficient space in tray 2, the C-grade headphones can be left on the tray, waiting for a later tray to have space before transferring them). After the current sorting is completed, the positioning drive 231 and the blocking drive 233 reset, and the conveyor belt 22 can transport trays 1 and 2 to the next process (such as unloading, packaging, etc.). Of course, the above is only one way to transfer headphones. In specific implementation, it can be adjusted according to the production rhythm, as long as it can achieve the goal of placing A-grade and B-grade headphones in the same tray, and B-grade and C-grade headphones in the same tray. When the sorting requirement is to place A-grade, B-grade, and C-grade headphones separately in different trays, three tray positioning components 23 can be set up to position the three trays respectively. When transferring headphones, the aforementioned transfer process can be referred to, so that each tray on the conveyor belt 22 contains only one grade of headphones.
