[0075] The rotary pressing mechanism 2 includes a magnetic clamp 201 for holding the ear rod end cap 300, a clamping power unit 202 for closing the magnetic clamp 201, and a pressing transmission unit 203 for driving the magnetic clamp 201 to rotate; wherein, the magnetic clamp 201 has a loading state in which it is driven by the pressing transmission unit 203 to rotate inward so as to put the ear rod end cap 300 into the magnetic clamp 201; and a pressing state in which it is driven by the pressing transmission unit 203 to rotate outward so as to flip the ear rod end cap 300 up and down and press it downward onto the tail end of the earphone ear rod 200.

[0076] The rotating pressure-holding mechanism 3 includes a pressure-holding head 301 and a pressure-holding transmission unit for driving the pressure-holding head 301 to flip down and press against the ear rod end cap 300 that is already clamped to the ear rod 200.

[0077] The dispensing robot 500 is used to dispense adhesive onto the tail end of the earphone stem 200; the pressing and rotating drive mechanism 600 is used to drive the pressing and rotating transmission unit 203 to drive the rotating pressing mechanism 2 to rotate; the pressure holding power mechanism 700 is used to drive the rotating pressure holding mechanism 3 to drive the rotating pressure holding mechanism 3 to rotate.

[0078] The headphone dispensing assembly and pressure-holding device provided in this embodiment has the following steps when it is necessary to install the ear stem end cap 300 to the tail end of the headphone ear stem 200:

[0079] S10: The press-fitting rotary drive mechanism 600 is activated, causing the press-fitting transmission unit 203 to drive the magnetic clamp 201 to rotate inward to the loading state, avoiding the fixture acupoint 101; then, the earphone fixture 100 with the earphone stem 200 fixed is placed on the fixture acupoint 101 of the module base 1, ensuring that the tail end of the earphone stem 200 protrudes upward.

[0080] S20: The dispensing robot 500 dispenses glue at the end of the earphone stem 200;

[0081] S30: Operate the rotary pressing mechanism 2. The specific steps are as follows:

[0082] S301: The worker manually or through the loading robot opens the magnetic clamp 201, and then puts the ear rod end cap 300 into the magnetic clamp 201;

[0083] S302: The clamping power unit 202 closes the magnetic clamp 201, so that the magnetic clamp 201 holds the ear rod end cap 300.

[0084] S303: The press-fitting rotary drive mechanism 600 is activated, causing the press-fitting transmission unit 203 to drive the magnetic clamp 201 to rotate outward to the pressing state, and the ear stem end cap 300 is pressed downward into the earphone ear stem 200 that has been glued.

[0085] S304: The worker manually or through the loading robot opens the magnetic clamp 201 to release the ear rod end cap 300; the pressing transmission unit 203 drives the magnetic clamp 201 to rotate inward to the loading state;

[0086] S40: The pressure holding power mechanism 700 is activated, causing the pressure holding transmission unit to drive the pressure holding head 301 to flip down to press the lug end cap 300 and perform pressure holding.

[0087] Through the above steps, the headphone assembly pressure-holding module 400 achieves efficient and precise assembly of the ear rod end cap 300, reducing the difficulty of manual alignment and improving production efficiency.

[0088] See Figure 6 The press-fit transmission unit 203 includes a transmission joint 2031 rotatably connected to the module base 1, and an L-shaped connector 2032 connecting the transmission joint 2031 to the magnetic clamp 201. By connecting the drive end of the press-fit rotary drive mechanism 600 to the transmission joint 2031, the magnetic clamp 201 can be driven to rotate around the axis of the transmission joint 2031, thereby switching between the loading state and the pressing state.

[0089] The L-shaped connector 2032 is provided with a fixed clamping magnet 2033, and the magnetic clamp 201 includes a fixed clamping plate 2011 and a rotating clamping plate 2012. The fixed clamping plate 2011 is fixed to the L-shaped connector 2032, and an opening clamping fixed magnet 2013 is provided at one end of the fixed clamping plate 2011 away from the ear rod end cap 300. The middle part of the rotating clamping plate 2012 is hinged to the fixed clamping plate 2011, and the rotating clamping plate 2012 is provided with an opening movable magnet 2014 for magnetically connecting with the opening clamping fixed magnet 2013 to maintain the open clamping state, and a closing movable magnet 2015 for magnetically connecting with the fixed clamping magnet 2033 to maintain the closed clamping state.

[0090] The rotating clamp 2012 has an outwardly protruding operating part 2012a at one end away from the ear rod end cap 300. The clamping power unit 202 includes a clamp pusher 2021 and a pusher linear drive mechanism for driving the clamp pusher 2021 to move up and down.

[0091] in:

[0092] The linear drive mechanism drives the clamping plate pusher 2021 upward, so that after the clamping plate pusher 2021 pushes the operating part 2012a upward, the rotating clamping plate 2012 rotates to the clamping state.

[0093] The linear drive mechanism drives the clamping plate pusher 2021 downward, so that after the clamping plate pusher 2021 pushes the operating part 2012a downward, the rotating clamping plate 2012 rotates to the open clamping state.

[0094] When it is necessary to open the magnetic clamp 201, push the operating part 2012a downward to make the rotating clamp 2012 rotate to the open clamping state;

[0095] At this time, the opening and closing movable magnet 2014 interacts with the opening and closing fixed magnet 2013 on the fixed clamping plate 2011, and the magnetic clamp 201 remains open, in preparation for the insertion of the ear rod end cap 300.

[0096] When it is necessary to close the magnetic clamp 201, the linear drive mechanism of the push wheel drives the clamping plate push wheel 2021 upward, and the clamping plate push wheel 2021 pushes the operating part 2012a from bottom to top, thereby causing the rotating clamping plate 2012 to rotate to the clamping state.

[0097] At this time, the movable clamping magnet 2015 on the rotating clamping plate 2012 interacts with the fixed clamping magnet 2033 on the fixed clamping plate 2011, and the magnetic clamp 201 remains closed, holding the ear rod end cap 300.

[0098] The pressure-holding transmission unit includes a pressure-holding rotating seat 302, a pressure-holding slider 303, and a pressure-holding spring 304. The pressure-holding rotating seat 302 is hinged to the module base 1; the pressure-holding slider 303 is slidably connected to the pressure-holding rotating seat 302; wherein, the pressure-holding head 301 is mounted on the pressure-holding slider 303; the pressure-holding spring 304 is located on the side of the pressure-holding slider 303 away from the ear rod end cap 300, and is used to drive the pressure-holding head 301 to elastically press the ear rod end cap 300 downward.

[0099] The design of the pressure-holding spring 304 enables the pressure-holding head 301 to elastically press the lug end cap 300, ensuring the consistency and stability of the assembly.

[0100] Optionally, a rotating buckle 305 is provided on the side of the pressure-holding rotating seat 302. The module base 1 is provided with a buckle limiting plate 3021 that engages with the rotating buckle 305; when the pressure-holding transmission unit drives the pressure-holding head 301 to press down on the ear rod end cap 300, the rotating buckle 305 engages with the buckle limiting plate 3021.

[0101] The snap-fit ​​design of the buckle limit plate 3021 and the rotating buckle 305 ensures that the position of the pressure holding head 301 will not change unexpectedly during the pressure holding process, thus improving the safety of operation. When the pressure holding is completed and the earphone fixture 100 needs to be removed, the worker can manually or through a robotic arm to open the rotating buckle 305.

[0102] See Figure 7 Optionally, the pressure-holding rotary seat 302 is provided with a pin hole 3022 on its side. The pressure-holding power mechanism 700 includes a pressure-holding pin 4 that is plugged into and pulled into the pin hole 3022, and a pressure-holding rotary drive mechanism 5 that drives the pressure-holding pin 4 to rotate the pressure-holding rotary seat 302.

[0103] Furthermore, the headphone dispensing assembly and pressure holding device also includes an XY bidirectional adjustment platform 800, which is located on the side of the headphone assembly and pressure holding module 400, and the dispensing robot 500, the pressing rotary drive mechanism 600, and the pressure holding power mechanism 700 are all located on the XY bidirectional adjustment platform 800.

[0104] The XY bidirectional adjustment platform 800 is used to adjust the position of the press-fitting rotary drive mechanism 600 and the pressure-holding power mechanism 700, so that while the press-fitting rotary drive mechanism 600 and the transmission joint 2031 are connected, the pressure-holding pin 4 is also smoothly inserted into the pin hole 3022.

[0105] The headphone dispensing assembly and pressure holding device provided in this embodiment has the following beneficial effects:

[0106] ① High degree of automation: Through automated components such as the dispensing robot 500, the pressing rotary drive mechanism 600, and the pressure holding power mechanism 700, the automatic dispensing, pressing and pressure holding of the ear rod end cap 300 is realized, which greatly reduces manual operation and improves production efficiency.

[0107] ② High assembly precision: The precise control of the rotary pressing mechanism 2 and the pressure holding mechanism ensures the precise assembly of the ear rod end cap 300 and the earphone ear rod 200, reducing the defect rate.

[0108] ③ Easy to operate: The ingenious design of the magnetic clamp 201 and the pressure holding head 301 makes the installation and fixing process of the ear rod end cap 300 simple and easy, reducing the difficulty of operation for workers.

[0109] ④ Good safety: The design of the buckle limit plate 3021 and the rotating buckle 305 ensures the stability of the pressure head 301 during the pressure holding process, avoiding accidental injury.

[0110] ⑤ High adaptability: The use of the XY bidirectional adjustment platform 800 makes the headphone assembly pressure holding module 400 detachable for maintenance, reducing the difficulty of maintenance.

[0111] In summary, the headphone dispensing assembly and pressure holding device provided in this embodiment has significant advantages in improving the automation level of headphone production, ensuring product quality, and increasing production efficiency.
