Description

Technical Field

[0001] This utility model relates to the field of headphone manufacturing technology, specifically to an automatic headphone feeding 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 a speaker unit placed close to the ear. 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, batteries, speaker units, and housings. After assembly, multiple tests are required, such as functional tests, acoustic tests, and radio frequency tests. During each process, the product / component needs to be placed into the corresponding equipment and removed after the equipment completes its operation. Products / parts are usually placed on trays for easy centralized transfer. To improve efficiency, loading and unloading devices are generally used to put products / parts from the trays into the equipment or to remove products / parts from the equipment and put them back into the trays. However, manual monitoring of the tray status is still required to remove the trays of processed products in a timely manner. The degree of automation is not high. If human negligence fails to detect the completion of the operation in time, the equipment will be idle, affecting the efficiency of the operation. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an automatic headphone dispensing device.

[0004] This utility model is achieved using the following solution: An automatic headphone dispensing device includes a chassis, a dispensing bin disposed on the chassis, a conveying mechanism disposed on the dispensing bin, and a first lifting mechanism and a second lifting mechanism disposed on the dispensing bin for lifting a material tray.

[0007] Furthermore, the automatic headphone discharging device also includes a first limiting mechanism, a second limiting mechanism, a third limiting mechanism, and a fourth limiting mechanism for limiting the material tray. The first limiting mechanism and the third limiting mechanism are disposed on the first upright plate, and the second limiting mechanism and the fourth limiting mechanism are disposed on the second upright plate.

[0019] 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.

[0020] Reference Figures 1 to 4This utility model provides an automatic headphone dispensing device, including a housing 1, a dispensing bin 2 disposed on the housing 1, a conveying mechanism 3 disposed on the dispensing bin 2, and a first lifting mechanism 4 and a second lifting mechanism 5 disposed on the dispensing bin 2 for lifting the trays. The dispensing bin 2 is divided into a stacking area and a dispensing area along the conveying direction of the conveying mechanism 3, and the lifting mechanisms are disposed in the stacking area. The stacking area is used to receive the incoming trays one by one and stack them into a pile. After a preset number of trays are stacked, the conveying mechanism 3 transfers the entire pile of trays to the dispensing area. Figure 1 From the perspective of the discharge bin 2, the front side is the discharge area and the rear side is the stacking area.

[0021] The first lifting mechanism 4 and the second lifting mechanism 5 are symmetrically arranged on both sides of the conveying mechanism 3. Both the first lifting mechanism 4 and the second lifting mechanism 5 include a lifting drive 41 connected to the discharge hopper 2, a lifting frame 42 connected to the output end of the lifting drive 41, and a lifting assembly 43 rotatably connected to the lifting frame 42. The lifting assembly 43 moves vertically under the drive of the lifting drive 41, thereby lifting the material tray on the conveying mechanism 3 upwards, facilitating the flow of the next material tray into the stacking area. In this embodiment, the lifting drive 41 can be a cylinder.

[0022] like Figure 3 As shown, the lifting assembly 43 includes a rotating component 431 connected to the lifting frame 42, a rotating plate 432 disposed on the rotating component 431, a connecting component 433 disposed on the lifting frame 42, and a spring 434 connecting the connecting component 433 and the rotating component 431. In the initial state, the top surface of the rotating plate 432 is approximately parallel to the horizontal plane (and the rotating plate 432 is designed to only rotate upwards). When the lifting drive component 41 drives the lifting frame 42 downwards, the rotating plate 432 is pushed upwards by the side of the tray and rotates at a certain angle. After the rotating plate 432 passes the lowest tray, the rotating component 431 resets under the action of the spring 434, and the rotating plate 432 returns to its initial position. At this time, the lifting drive component 41 drives the lifting frame 42 upwards, and the top surface of the rotating plate 432 contacts the bottom surface of the tray, thus lifting the tray upwards and allowing it to leave the conveying mechanism, making room for the next tray to enter.

[0023] The discharge hopper 2 includes a bottom support 21, a first upright plate 22 and a second upright plate 23 vertically mounted on the bottom support 21, and a reinforcing member 24 connecting the tops of the first upright plate 22 and the second upright plate 23. The first upright plate 22 and the second upright plate 23 are parallel to each other and have a gap between them, with the stacking area and the discharge area located within the gap. Both the first upright plate 22 and the second upright plate 23 are provided with a first opening 25 for the lifting assembly 43 to pass through. The vertical dimension of the first opening 25 needs to be greater than the stroke of the lifting assembly.

[0024] The conveying mechanism 3 includes a first conveyor belt assembly 31 disposed inside the first upright plate 22, a second conveyor belt assembly 32 disposed inside the second upright plate 23 and cooperating with the first conveyor belt assembly 31, a drive shaft 33 connecting the first conveyor belt assembly 31 and the second conveyor belt assembly 32, and a drive motor 34 disposed outside the first upright plate 22 for driving the drive shaft 33. There is a certain gap between the first conveyor belt assembly 31 and the first upright plate 22, and there is also a certain gap between the second conveyor belt assembly 32 and the second upright plate 23, so that both sides of the material tray can extend beyond the first conveyor belt assembly 31 and the second conveyor belt assembly 32 respectively, facilitating the rotating plate 432 to lift the material tray from below.

[0025] A second limiting strip 27 is provided on the inner side of the first upright plate 22 and the inner side of the second upright plate 23. The second limiting strip 27 is located close to the starting end of the conveying mechanism 3, and there is a gap between the second limiting strip 27 and the conveying mechanism 3 for the material tray to pass through. The two second limiting strips 27 can limit the position of the material tray and prevent the material tray from shifting or falling off during the up and down movement.

[0026] The automatic headphone dispensing device further includes a first limiting mechanism 6, a second limiting mechanism 6a, a third limiting mechanism 6b, and a fourth limiting mechanism 6c for limiting the material tray. The first limiting mechanism 6 and the third limiting mechanism 6b are disposed on the first upright plate 22, and the second limiting mechanism 6a and the fourth limiting mechanism 6c are disposed on the second upright plate 23. The first limiting mechanism 6 and the second limiting mechanism 6a are located between the stacking area and the dispensing area, and the first limiting mechanism 6 and the second limiting mechanism 6a are symmetrically arranged. The third limiting mechanism 6b and the fourth limiting mechanism 6c are located at the end of the dispensing area, and the third limiting mechanism 6b and the fourth limiting mechanism 6c are symmetrically arranged. The first limiting mechanism 6 and the second limiting mechanism 6a cooperate with the aforementioned second limiting strip 27 to restrict the material tray within the stacking area, ensuring that the material trays are stacked neatly. Similarly, the third limiting mechanism 6b and the fourth limiting mechanism 6c can restrict the material tray within the dispensing area.

[0027] Both the first limiting mechanism 6 and the second limiting mechanism 6a include a limiting drive member 61 and a first limiting strip 62 connected to the output end of the limiting drive member 61. The first upright plate 22 and the second upright plate 23 are each provided with a second opening 26 for the first limiting strip 62 to pass through. The limiting drive member 61 can drive the first limiting strip 62 to move towards the inside of the discharge hopper 2, thereby limiting the material tray. After the material tray is stacked to a predetermined height, the limiting drive member 61 resets, causing the first limiting strip 62 to retract and exit the material tray coverage area, making way for the conveying mechanism 3 to convey the material tray. In this embodiment, the limiting drive member 61 can be a cylinder.

[0028] A blocking mechanism 7 is provided at the bottom of the discharge hopper, located between the stacking area and the discharge area. The blocking mechanism 7 includes a blocking drive 71 connected to the discharge hopper 2 and a blocking member 72 connected to the output end of the blocking drive 71. When the lowest tray enters the stacking area, the blocking drive 71 drives the blocking member 72 to move upwards, causing the tray to stop in the stacking area and ensuring stacking accuracy. In this embodiment, the blocking drive 71 can be a cylinder.

[0029] A lifting mechanism 8 is provided at the bottom of the discharge hopper 2 corresponding to the discharge area. The lifting mechanism 8 includes a lifting drive 81 connected to the discharge hopper 2 and a lifting frame 82 connected to the output end of the lifting drive 81. When there are still stacked trays in the discharge area, if a tray from the stacking area enters, the rotation of the first conveyor belt assembly 31 and the second conveyor belt assembly 32 of the conveying mechanism 3 will cause friction with the trays in the discharge area. At this time, the lifting mechanism 8 can lift the stacked trays away from the conveying mechanism 3, reducing resistance and preventing damage to the trays and the two conveyor belt assemblies due to prolonged friction. In this embodiment, the lifting drive 81 can be a cylinder.

[0030] In addition, the first vertical plate 22 and the second vertical plate 23 can also be equipped with several sensors (such as photoelectric sensors). The sensors can be set at the corresponding stacking area and the discharge area. For example, sensors can be set at the upper and lower positions in the stacking area. The lower sensor can monitor whether the material tray flows in, while the upper sensor can monitor whether the material tray is stacked to the preset quantity.

[0031] In actual operation, the two ends of the conveying mechanism of this application are respectively connected to other equipment (or other conveying mechanisms). For example, one end of the conveying mechanism 3 corresponding to the stacking area can be connected to the discharge station of the processing equipment to facilitate receiving the material trays from the processing equipment, while the other end of the conveying mechanism 3 corresponding to the discharge area can send the stacked material trays to the next process through the conveying mechanism there. After the processed products are placed on the first tray, the first tray flows into the stacking area. The lifting mechanism lifts the first tray, and then the second tray flows from the processing equipment into the stacking area. The lifting mechanism repeats the lifting action, stacking the first tray on top of the second tray and lifting both trays together. This process continues until a preset number of trays is reached. After the preset number of trays is reached, the first limit bar 62 of the first limit mechanism 6 and the second limit mechanism 6a retracts, and the conveying mechanism 3 transfers the entire stack of trays to the discharge area. If the trays are allowed to flow to the next process (whether this is allowed depends on the specific rhythm of the production line), the entire stack of trays can flow directly into the conveying mechanism to be sent to the next process. If the trays are not allowed to flow to the next process, the entire stack of trays is temporarily stored in the discharge area, while the stacking area continues to perform stacking operations. Of course, if it is not necessary to transfer to the next process during actual production, the stacked trays can wait in the discharge area for the staff to pick them up.
