Description

Technical Field

[0001] This utility model relates to the field of headphone manufacturing technology, specifically to an automatic headphone feeding bin. 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, batteries, sound-producing units, and housings. After assembly, various tests are required, such as functional tests, acoustic tests, and radio frequency tests. These different processes require different equipment, and the product / component must be placed into the corresponding equipment during each operation. In traditional operations, products / parts are usually placed on a tray, and people manually put the products / parts from the tray into the corresponding equipment. Although there are now mechanisms that can automatically transfer products / parts from the tray to the equipment, it still requires manual transfer of the tray. Workers need to pay attention to the operation at all times in order to replenish the tray in time. The efficiency is still not high and it is difficult to meet the needs of automated operation. Utility Model Content

The pushing mechanism includes a first pushing component and a second pushing component arranged in a counter-support configuration. The first pushing component is disposed on the first support plate, and the second pushing component is disposed on the second support plate. Both the first and second pushing components include a first pushing cylinder arranged along the conveying direction of the conveying mechanism, a pushing bracket connected to the output end of the first pushing cylinder, a second pushing cylinder connected to the pushing bracket, and a pushing element connected to the output end of the second pushing cylinder. Both the first and second support plates are provided with a second opening for the pushing element to pass through. The second pushing cylinder pushes the pushing element to move toward the conveying mechanism.

[0008] Furthermore, both the first opening of the first support plate and the first opening of the second support plate are provided with positioning components, the positioning components including a positioning drive and a positioning element connected to the output end of the positioning drive.

[0009] Furthermore, both the inner sides of the first support plate and the inner sides of the second support plate are provided with baffles. The baffles are located between the waiting area and the feeding area, and there is a gap between the lower end of the baffles and the conveying mechanism for the passage of the feeding tray.

[0010] Furthermore, the conveying mechanism includes two parallel conveyor belt assemblies, a drive motor disposed on the outside of the first support plate, and a transmission shaft for connecting the drive motor and the conveyor belt assemblies, wherein one of the conveyor belt assemblies is disposed on the inside of the first support plate, and the other conveyor belt assembly is disposed on the inside of the second support plate.

[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 5 This utility model provides an automatic headphone feeding bin, including a housing 1, a storage rack 2 vertically mounted on the housing 1 for storing trays, and a conveying mechanism 3 at the bottom of the storage rack 2 for conveying trays. The storage rack is arranged sequentially along the conveying direction of the conveying mechanism 3, comprising a storage area, a waiting area, and a feeding area. The storage rack 2 is equipped with a lifting mechanism 4 for lifting trays corresponding to the waiting area. Both the storage area and the waiting area have several trays stacked on top of each other. The lifting mechanism 4 can lift the stacked trays in the waiting area, leaving only the bottom tray. The bottom tray is then conveyed by the conveying mechanism 3 to the feeding area, awaiting feeding to the corresponding equipment. After feeding is completed, the lifting mechanism 4 and the conveying mechanism 3 can repeat the aforementioned operation to deliver the bottom tray.

[0022] The storage rack 2 includes a bottom support 21 connected to the chassis 1, a first support plate 22 and a second support plate 23 vertically mounted on the bottom support 21, with a gap between the first support plate 22 and the second support plate 23. The storage area, waiting area, and loading area are located at the gap. The conveying mechanism 3 is located between the first support plate 22 and the second support plate 23. The first lifting component 41 is connected to the outside of the first support plate 22, and the second lifting component 42 is connected to the outside of the second support plate 23. The gap between the first support plate 22 and the second support plate 23 can be adaptively set according to the size of the material tray. Several photoelectric sensors can be installed on the first support plate 22 and the second support plate 23, for example, at the positions corresponding to the storage area, the waiting area, and the loading area, so as to determine whether there is a material tray at each position or whether the material tray has been placed.

[0023] The lifting mechanism 4 includes a first lifting component 41 and a second lifting component 42 symmetrically arranged. The first lifting component 41 and the second lifting component 42 are located on both sides of the conveying mechanism 3, with the longitudinal centerline as the reference. The first lifting component 41 and the second lifting component 42 can lift the material tray from both sides. The symmetrical force on the material tray avoids the tilt that may be caused by unilateral lifting and maintains the stability of the posture. Bilateral lifting reduces the dependence on the rigidity of the material tray itself, so that even thin or loaded trays can be safely, stably and reliably lifted off the conveying mechanism 3 as a whole.

[0024] like Figure 3As shown, both the first lifting assembly 41 and the second lifting assembly 42 include a first lifting connecting frame 411 connected to the storage rack, a first lifting drive member 412 connected to the first lifting connecting frame 411, a second lifting connecting frame 413 connected to the first lifting drive member 412, a second lifting drive member 414 vertically disposed on the second lifting connecting frame 413, and a lifting frame 415 connected to the output end of the second lifting drive member 414. The initial position of the lifting frame 415 is higher than that of the conveying mechanism 3, but does not exceed the top surface of the lowest tray. Both the first support plate 22 and the second support plate 23 are provided with a first opening 24 for the lifting frame to pass through. The second lifting assembly 42 can drive the lifting frame 415 to move through the opening and above the conveying mechanism 3. The lifting frame 415 is provided with several teeth, and the material tray has pre-set grooves corresponding to the teeth. These grooves penetrate the top surface of the material tray, and their width is slightly greater than the thickness of the teeth, allowing the teeth to be inserted into them. During lifting, the first lifting drive 412 drives the second lifting drive 414 to move towards the material tray, i.e., the lifting frame 415 moves towards the material tray, causing the teeth of the lifting frame 415 to pass through the first opening 24 and insert into the groove of the lowest material tray. Then, the second lifting drive 414 drives the lifting frame 415 upwards... The lifting frame 415 can then lift the entire stack of trays above, with a lifting height slightly greater than the height of a single tray but less than the height of two trays stacked together, ensuring that only the bottom tray remains on the conveying mechanism 3. The conveying mechanism 3 then sends the bottom tray into the loading area. Subsequently, the second lifting drive 414 descends to its reset position, and the first lifting drive 412 retracts, causing the entire stack of trays to fall back onto the conveying mechanism 3. After loading is complete in the loading area, the aforementioned operation can be repeated to send the bottom tray back into the loading area. After the trays enter the loading area, products can be loaded here (i.e., products are transferred to the corresponding equipment via a robotic arm). Empty trays then flow out via a separately installed conveyor belt (connected to the conveying mechanism 3), or they can enter the corresponding equipment via a separately installed conveyor belt for further loading. Additionally, a photoelectric sensor can be installed on the lifting frame 415. The photoelectric sensor confirms that the groove of the bottom tray and the teeth of the lifting frame 415 are initially aligned vertically, allowing the teeth to insert into the groove.

[0025] The storage rack is equipped with a pushing mechanism 5, which is located between the feeding area and the storage area. The pushing mechanism 5 includes a first pushing component 51 and a second pushing component 52 arranged in a counter-support configuration. The first pushing component 51 is disposed on the first support plate 22, and the second pushing component 52 is disposed on the second support plate 23. Both the first pushing component 51 and the second pushing component 52 include a first pushing cylinder 511 arranged along the conveying direction of the conveying mechanism 3, a pushing bracket 512 connected to the output end of the first pushing cylinder 511, a second pushing cylinder 513 connected to the pushing bracket 512, and a pushing element 514 connected to the output end of the second pushing cylinder 513 (in the attached drawings, the second pushing cylinder 513 and the pushing element 514 are partially offset to indicate the forward movement position of the pushing element 514). The length of the pushing element 514 is at least equal to the stacking height of the material trays. In this embodiment, the first ejector cylinder can drive the pusher bracket 512 to move in the front-to-back direction, and the second pusher cylinder 513 can drive the pusher to move in the left-to-right direction. Both the first support plate 22 and the second support plate 23 are provided with a second opening 25 for the pusher 514 to pass through. The second pusher cylinder 513 pushes the pusher 514 towards the conveyor mechanism 3. The shape of the second opening 25 must allow the pusher 514 to enter above the conveyor belt assembly 31 and to move a certain distance forward and backward. The pusher mechanism 5 is used to align stacked pallets. When the pallets enter the storage area, the relative positions of the upper and lower pallets may shift. The pusher 514 first enters above the conveyor belt assembly 31 and moves to the front (within a certain distance). Figure 1 (Taking the perspective of the material tray as an example), after the material tray enters the storage area, the pusher 514 moves to the rear, the material tray and the pusher 514 come into contact and are pushed, so that the position of the entire stack of material trays is aligned, and then the pusher 514 can be reset.

[0026] Both the first opening 24 of the first support plate 22 and the first opening 24 of the second support plate 23 are provided with positioning components 6. The positioning components 6 include a positioning drive 61 and a positioning component 62 connected to the output end of the positioning drive 61. In this embodiment, the positioning drive 61 is a cylinder. The first opening 24 is generally rectangular. One positioning component 6 can be provided at one end of the first opening 24, or one can be provided at each end of the first opening 24. The material tray is pre-set with a positioning groove that cooperates with the positioning component 62. The positioning groove is located near the end of the material tray. The positioning groove is arc-shaped, and the end of the positioning component 62 is also arc-shaped. The width of the positioning groove is greater than that of the positioning component 62. If the position of the material tray is offset, when the positioning component 62 contacts the inner wall of the positioning groove, it can push the positioning groove to a predetermined position. Specifically, after receiving the photoelectric sensor signal, the positioning drive 61 can drive the positioning insertion into the positioning groove of the material tray to position the material tray, so that the lifting frame 415 can be accurately inserted into the groove of the material tray.

[0027] Both the inner side of the first support plate 22 and the inner side of the second support plate 23 are provided with baffle strips 26. The baffle strips 26 are located between the waiting area and the feeding area, and there is a gap between the lower end of the baffle strip 26 and the conveying mechanism for the passage of the feeding tray. The trays are stacked in a pile. When the entire pile of trays enters the waiting area, the baffle strips 26 can block the trays, ensuring that the trays remain in the waiting area.

[0028] The conveying mechanism 3 includes two parallel conveyor belt assemblies 31, a drive motor 32 disposed on the outside of the first support plate 22, and a transmission shaft 33 for connecting the drive motor 32 and the conveyor belt assemblies 31. One conveyor belt assembly 31 is disposed on the inner side of the first support plate 22, and the other conveyor belt assembly 31 is disposed on the inner side of the second support plate 23. There is a gap between the two conveyor belt assemblies 31, and during conveying, the two conveyor belt assemblies 31 respectively contact the two sides of the material tray.

[0029] A first lifting mechanism 7 is provided at the bottom of the storage rack corresponding to the waiting area, and a second lifting mechanism 8 is provided at the bottom of the storage rack corresponding to the storage area. Both the first lifting mechanism 7 and the second lifting mechanism 8 include a lifting drive 71 connected to the storage rack and a lifting bracket 72 connected to the output end of the lifting drive 71. In this embodiment, the lifting drive 71 is a cylinder. When the conveying mechanism 3 sends out the tray at the bottom of the waiting area, the first lifting mechanism 7 can lift the tray in the storage area to avoid friction between the tray and the conveyor belt, and to avoid scratches, wear and dust contamination caused by relative sliding. Since the lifting frame 415 is initially higher than the conveyor belt, after the lifting frame 415 is withdrawn, the entire stack of trays will fall freely under the action of gravity and hit the conveyor belt assembly 31. This may cause the products in the tray to shift or even be damaged. The second lifting mechanism 8 in the waiting area can avoid this situation. Specifically, after the bottom tray in the waiting area is delivered, the second lifting mechanism 8 can lift upwards, so that the lifting bracket 72 contacts the bottom of the tray. After the lifting mechanism 4 is reset, the second lifting component is reset again, so that the entire stack of trays moves down steadily until the bottom tray contacts the conveyor belt assembly 31, thus preventing the entire stack of trays from suddenly falling and hitting the conveyor belt assembly 31.

[0030] A blocking mechanism 9 is provided at the bottom of the storage rack. The blocking mechanism 9 is located between the storage area and the waiting area. The blocking mechanism 9 includes a blocking drive 91 and a blocking member 92 connected to the output end of the blocking drive 91. In this embodiment, the blocking drive 91 is a cylinder. After the pushing mechanism 5 aligns the material tray, the blocking drive 91 drives the blocking member 92 to rise. The blocking member 92 can block the material tray and prevent the material tray from flowing out of the storage area.

[0031] In operation, the conveyor mechanism 3 can be connected to additional conveyor belts on both its front and rear sides. After the conveyor belt delivers a stack of pallets (designated as pallet A) into the conveyor mechanism 3, the conveyor mechanism 3 moves pallet A to the waiting area, while another stack of pallets (designated as pallet B) enters the storage area. The conveyor mechanism 3 then sequentially delivers the bottom pallet of pallet A to the loading area until the entire stack is loaded. After entering the loading area, the pallets can be loaded directly or transported to the corresponding loading position via the additional conveyor belt. After pallet A is loaded, pallet B enters the waiting area, while a new pallet C enters the storage area. The conveyor mechanism 3 then sequentially delivers the bottom pallet of pallet B to the loading area, and so on, completing the cyclical automatic loading operation.
