Description

Technical Field

[0001] This invention relates to the field of headphone manufacturing technology, and in particular to a headphone shell fixing fixture and a dispensing method using the headphone shell fixing fixture. Background Technology

[0002] With the development of technology, wireless earphones are becoming increasingly popular among users. During the manufacturing process of wireless earphones, the front shell and the middle and rear shells need to be bonded together with adhesive. However, since the front shell and the middle and rear shells are usually connected by a flexible circuit board, the flexible circuit board will block part of the front shell. Therefore, during the adhesive bonding process, the middle and rear shells and the flexible circuit board need to be flipped at a certain angle to expose the part of the front shell that is blocked. Then, the adhesive bonding process is performed again on the exposed part.

[0003] Traditional flipping processes rely on manual flipping, which makes it difficult to guarantee the angle and force of each flip. If the flipping force is too small, the middle and rear shells can easily collide with the needle of the dispensing equipment; if the flipping force is too large, it can easily cause the flexible circuit board to tear. Summary of the Invention

[0004] The main objective of this invention is to provide a headphone shell fixing fixture, which aims to improve the problem of manually flipping the middle and rear shells and flexible circuit boards during the dispensing process of headphone shells.

[0005] To achieve the above objectives, this invention proposes an earphone shell fixing fixture applied to the earphone shell dispensing process. The earphone shell includes a front shell and a middle and rear shell, which are connected by a flexible circuit board. The surface of the front shell facing the middle and rear shell includes a first region and a second region. The first region can be shielded by the flexible circuit board, while the second region is not shielded. The earphone shell fixing fixture includes a base, a front shell fixing component, a middle and rear shell fixing component, and a driving component. The front shell fixing component is used to fix the front shell. The middle and rear shell fixing component is used to fix the middle and rear shell, and both the front shell fixing component and the middle and rear shell fixing component are disposed on the base. The driving component drives and connects to the middle and rear shell fixing component and drives the middle and rear shell fixing component to rotate. When the middle and rear shell fixing component is rotated to a first position, the first region is exposed and dispensing is performed on the first region to complete the first dispensing process. When the middle and rear shell fixing component is rotated to a second position, the first region is shielded by the flexible circuit board, and dispensing is performed on the second region to complete the second dispensing process.

[0006] Optionally, the front shell fixing assembly includes:

[0007] A front housing positioning block, wherein the front housing positioning block is disposed on the base and has a front housing mounting groove; and

[0008] A cover plate, which is hinged to the front housing positioning block and can press against the front housing installed in the front housing mounting groove.

[0009] Optionally, the front shell positioning block is provided with a first magnetic attraction element, and the cover plate is provided with a second magnetic attraction element. When the cover plate presses the front shell, the first magnetic attraction element and the second magnetic attraction element are magnetically connected.

[0010] Optionally, the middle and rear shell fixing assembly includes:

[0011] A pad block is fixedly mounted on the base, and the pad block is set at an angle to the front shell positioning block;

[0012] A rear shell positioning block is movably connected to the pad block to fix the rear shell; the driving assembly drives the rear shell positioning block and drives it to rotate.

[0013] Optionally, the middle and rear shell positioning block is provided with a third magnetic attraction element, and the pad is provided with a fourth magnetic attraction element. When the driving assembly drives the middle and rear shell positioning block to flip to the second position, the third magnetic attraction element and the fourth magnetic attraction element are magnetically connected.

[0014] Optionally, the middle and rear shell fixing assembly further includes a clamping member for clamping the middle and rear shell to the middle and rear shell positioning block.

[0015] Optionally, the middle and rear shell positioning block is provided with a middle and rear shell mounting groove and a connecting groove. The middle and rear shell mounting groove is used to install the middle and rear shell. The connecting groove connects to the middle and rear shell mounting groove, and the clamping member is interference-fitted with the connecting groove to support the middle and rear shell.

[0016] Optionally, the driving component includes:

[0017] Rotary cylinder; and

[0018] A plug-in assembly is connected to the rotary cylinder and is inserted into the middle and rear shell fixing assembly so that when the rotary cylinder drives the plug-in assembly to rotate, it causes the middle and rear shell fixing assembly to flip.

[0019] Optionally, the plug-in assembly includes:

[0020] A finger cylinder, wherein the finger cylinder is drivenly connected to the rotary cylinder;

[0021] The gripper, wherein the gripper is drivenly connected to the finger cylinder; and

[0022] A pin is connected to the jaws and is used to insert into the middle and rear housing fixing assembly.

[0023] Optionally, the drive assembly further includes a slide cylinder, which is throttle-connected to the rotary cylinder and can drive the rotary cylinder to move along the extension direction of the plug-in assembly, so that the plug-in assembly can be inserted into or disengaged from the middle and rear shell fixing assembly.

[0024] This invention also proposes a dispensing method using the aforementioned headphone housing fixing fixture. The headphone housing includes a front shell and a middle / rear shell, the front shell and the middle / rear shell being connected by a flexible circuit board. The surface of the front shell facing the middle / rear shell includes a first region and a second region. The first region can be shielded by the flexible circuit board, while the second region is not shielded by the flexible circuit board. The dispensing method includes:

[0025] The front shell is installed on the front shell fixing assembly, and the middle and rear shells are installed on the middle and rear shell fixing assembly.

[0026] The driving component drives the middle and rear shell fixing component to flip to the first position to expose the first area, and applies adhesive to the first area;

[0027] The drive component drives the middle and rear shell fixing component to flip to the second position and applies adhesive to the second area.

[0028] The technical solution of this invention involves placing the front shell fixing assembly and the middle and rear shell fixing assembly on a base. A driving assembly drives the middle and rear shell fixing assembly to rotate, allowing the middle and rear shell on the middle and rear shell fixing assembly to rotate relative to the front shell on the front shell fixing assembly. This, in turn, causes the flexible circuit board connected between the front shell and the middle and rear shell to rotate, exposing the first area. This achieves the effect of automatically rotating the middle and rear shell to expose the first area, avoiding the risk of the flexible circuit board tearing from the earphone shell due to manual rotation. It also saves manpower and improves production efficiency. Furthermore, by first rotating the middle and rear shell fixing assembly to a first position under the drive of the driving assembly, and then rotating the middle and rear shell and the flexible circuit board to expose the first area and applying adhesive to the first area, and then driving the middle and rear shell fixing assembly to rotate to a second position and applying adhesive to the second area, the risk of the flexible circuit board lifting the adhesive applied to the front shell in the first adhesive application process is avoided during the second adhesive application process. This ensures better sealing after the front shell and the middle and rear shell of the earphone are assembled. Attached Figure Description

[0047] This invention proposes a fixture for fixing an earphone shell.

[0048] In the embodiments of the present invention, please refer to the reference. Figures 1 to 6This headphone housing fixing fixture is applied to the dispensing process of headphone housing 100. The headphone housing 100 includes a front shell 110 and a middle / rear shell 120. The front shell 110 and the middle / rear shell 120 are connected by a flexible circuit board. The surface of the front shell 110 facing the middle / rear shell 120 includes a first region 111 and a second region 112. The first region 111 can be shielded by the flexible circuit board, while the second region 112 is not shielded by the flexible circuit board. The headphone housing fixing fixture includes a base 200, a front shell fixing assembly 300, a middle / rear shell fixing assembly 400, and a drive assembly 500. The front shell fixing assembly 300 is used to fix the front shell. 110; The middle and rear shell fixing assembly 400 is used to fix the middle and rear shell 120. The front shell fixing assembly 300 and the middle and rear shell fixing assembly 400 are both disposed on the base 200; The driving assembly 500 drives and connects to the middle and rear shell fixing assembly 400, and drives the middle and rear shell 120 assembly to flip; When the middle and rear shell 120 assembly flips to the first position, the first area 111 is exposed and glue is applied to the first area 111 to complete the first glue application process; When the middle and rear shell 120 assembly flips to the second position, the first area 111 is covered by the flexible circuit board, and glue is applied to the second area 112 to complete the second glue application process.

[0049] To facilitate the installation of components such as speakers and circuit boards into the earphone housing 100, the earphone housing 100 includes a separate front shell 110 and a rear shell 120. A speaker is installed in one of the front shell 110 and the rear shell 120, and a battery is installed in the other. The battery and speaker are connected via a flexible circuit board. Therefore, when applying adhesive to the surface of the front shell 110 facing the rear shell 120, the flexible circuit board will partially obscure the surface of the front shell 110. For ease of description, the area obscured by the flexible circuit board is defined as the first region 111, and the area not obscured by the flexible circuit board is defined as the second region 112. To ensure a good seal between the front shell 110 and the rear shell 120, adhesive application is required to both the first region 111 and the second region 112 simultaneously. Therefore, when applying adhesive to the first region 111, the flexible circuit board needs to be flipped to expose the first region 111 and facilitate adhesive application by the dispensing machine. In this invention, the front shell fixing component 300 is used to fix the front shell 110, and the middle and rear shell fixing component 400 is used to fix the middle and rear shell 120. Both the front shell fixing component 300 and the middle and rear shell fixing component 400 are located on the base 200, ensuring that the front shell 110 and the middle and rear shell 120 are not too far apart, thus preventing the flexible circuit board from being torn. Specifically, when the front shell fixing component 300 fixes the front shell 110, it can fix the front shell 110 magnetically; or by providing a groove in which the front shell 110 is placed with an interference fit; or by providing multiple tensioning structures to clamp the front shell 110 from multiple directions, etc. Similarly, when the middle and rear shell fixing component 400 fixes the middle and rear shell 120, it can adopt a structure similar to that of the front shell fixing component 300, which will not be described in detail here.

[0050] The fixing fixture for the earphone shell 100 in this invention also includes a drive assembly 500, which drives the middle and rear shell fixing assembly 400 to rotate. It is understood that when the middle and rear shell fixing assembly 400 flips towards the front shell fixing assembly 300, it drives the middle and rear shell 120 to rotate towards the front shell 110 and close to it. Subsequently, the middle and rear shell 120 drives the flexible circuit board to flip, allowing the first area 111, previously obscured by the flexible circuit board, to be exposed. By providing the drive assembly 500 to drive the middle and rear shell fixing assembly 400, the manual flipping of the flexible circuit board can be replaced, thereby avoiding various instabilities caused by manual operation and ensuring a uniform flipping angle and force each time the flexible circuit board is flipped. Specifically, when the drive assembly 500 drives the rear shell fixing assembly 400 to the first position, the flexible circuit board flips over and exposes the first area 111 of the front shell 110 so that adhesive can be applied to the first area 111; when the drive assembly 500 drives the rear shell fixing assembly 400 to the first position, the flexible circuit board covers the first area 111 of the front shell 110, so that adhesive can be applied to the second area 112 that is not covered by the flexible circuit board.

[0051] Furthermore, the process of applying adhesive to the first region 111 in this invention is a first dispensing process, and the process of applying adhesive to the second region 112 is a second dispensing process. That is, this invention first applies adhesive to the first region 111 and then applies adhesive to the second region 112. This can prevent the adhesive in the second region 112 from being lifted up and detached from the front shell 110 when the flexible circuit board is flipped. This ensures that the adhesive after applying adhesive to the first region 111 and the second region 112 is more stable, thereby enabling the front shell 110 and the middle and rear shell 120 to have a good sealing effect after being assembled. If adhesive is applied to the second region 112 first, then when adhesive is subsequently applied to the first region 111, it is understood that the flexible circuit board needs to be flipped to expose the first region 111. During this flipping, the flexible circuit board may cause the surrounding adhesive to lift and detach from the front shell 110, resulting in missing adhesive in certain areas of the second region 112. This leads to poor sealing after the front shell 110 and the rear shell 120 are joined. It should be noted that during the second adhesive application process, since the flexible circuit board is blocking the first region 111, to facilitate adhesive application and avoid calculating complex dispensing paths, adhesive can be applied to the flexible circuit board simultaneously with the second region 112, ensuring a closed dispensing path.

[0052] The technical solution of this invention involves placing the front shell fixing assembly 300 and the middle and rear shell fixing assembly 400 on the base 200. The driving assembly 500 drives the middle and rear shell fixing assembly 400 to rotate, thereby allowing the middle and rear shell 120 on the middle and rear shell fixing assembly 400 to rotate relative to the front shell 110 on the front shell fixing assembly 300. This, in turn, causes the flexible circuit board connected between the front shell 110 and the middle and rear shell 120 to rotate, exposing the first area 111. This achieves the effect of automatically rotating the middle and rear shell 120 to expose the first area 111, avoiding the risk of the flexible circuit board tearing from the earphone shell 100 due to manual rotation. It also saves manpower and improves production efficiency. Furthermore, by first driving the rear shell fixing component 400 to the first position under the drive of the drive component 500, and then driving the rear shell 120 and the flexible circuit board to flip to expose the first area 111, and applying glue to the first area 111, and then driving the rear shell fixing component 400 to the second position under the drive of the drive component 500, and applying glue to the second area 112, the risk of the flexible circuit board lifting the glue applied to the front shell 110 in the first glue application process is avoided during the second glue application process, so as to ensure that the front shell 110 and the rear shell 120 of the earphone have better sealing performance after being assembled.

[0053] Furthermore, such as Figure 8 As shown, the front shell fixing assembly 300 includes a front shell positioning block 310 and a cover plate 320. The front shell 110 fixing block is disposed on the base 200 and has a front shell mounting groove. The cover plate 320 is hinged to the front shell positioning block 310 and can press the front shell 110 installed in the front shell mounting groove.

[0054] The front housing positioning block 310 is used to mount the front housing 110. By providing a front housing mounting groove on the front housing positioning block 310, the front housing 110 can be installed in the front housing mounting groove, thereby limiting the circumferential movement of the front housing 110. In addition, the front housing fixing assembly 300 also includes a cover plate 320 hinged to the front housing positioning block 310. The cover plate 320 can rotate relative to the front housing positioning block 310 to a state that can press the front housing 110 in the front housing mounting groove to avoid the risk of the front housing 110 tilting up. Alternatively, the cover plate 320 can be rotated to a position that avoids the front housing 110 from falling out of the front housing mounting groove, so that the user can remove and install the front housing 110 from the front housing positioning block 310 without any obstacles.

[0055] Specifically, the shape of the front housing mounting groove can be adapted to the shape of the front housing 110. When the cover plate 320 is hinged to the front housing positioning block 310, it can be directly hinged to the front housing positioning block 310. Alternatively, an adapter plate 330 can be fixedly installed on the front housing positioning block 310, and the cover plate 320 is directly hinged to the adapter plate 330 to achieve the effect of the cover plate 320 rotating relative to the front housing positioning block 310. The adapter plate 330 can be provided on the side wall of the front housing positioning block 310, and the adapter plate 330 is connected to the front housing positioning block 310 by screws to enhance the stability of the adapter plate 330 connected to the front housing positioning block 310. The upper edge of the cover plate 320 is hinged to the adapter plate 330 so that the cover plate 320 can be flipped relative to the adapter plate 330 to the side opposite to the upper surface of the front housing positioning block 310, and press the front housing 110 on the front housing positioning block 310 under the action of gravity.

[0056] Furthermore, such as Figure 8 As shown, the front shell positioning block 310 is provided with a first magnetic suction member, and the cover plate 320 is provided with a second magnetic suction member 340. When the cover plate 320 presses against the front shell 110, the first magnetic suction member and the second magnetic suction member 340 are magnetically connected.

[0057] When the cover plate 320 presses against the front shell 110, the second magnetic chuck 340 on the cover plate 320 is magnetically connected to the first magnetic chuck on the front shell positioning block 310. Therefore, when it is necessary to flip the cover plate 320 to a position that allows the front shell 110 to be removed from the front shell positioning block 310, in addition to overcoming the weight of the cover plate 320, it is also necessary to overcome the magnetic attraction between the cover plate 320 and the front shell positioning block 310. Thus, by magnetically connecting the cover plate 320 to the front shell positioning block 310, the stability of the cover plate 320 pressing against the front shell 110 is further improved, preventing the cover plate 320 from easily releasing its pressing effect on the front shell 110 under external force. If it is necessary to remove the pressing effect on the front shell 110, the operator only needs to lift the cover plate 320 upwards. This design makes the operation of the front shell fixing assembly 300 to fix the front shell 110 convenient and quick.

[0058] Alternatively, in other embodiments, when the cover plate 320 presses against the front shell 110, the cover plate 320 is also snapped into connection with the front shell positioning block 310. This configuration further improves the stability of the cover plate 320 pressing against the front shell 110. If it is necessary to remove the pressing action on the front shell 110, the operator only needs to lift the cover plate 320 upwards with force.

[0059] As an example, such as Figure 8As shown, the middle and rear shell fixing assembly 400 includes a pad 410 and a middle and rear shell positioning block 420. The pad 410 is fixedly disposed on the base 200, and the pad 410 is set at an angle to the front shell positioning block 310. The middle and rear shell positioning block 420 is movably connected to the pad 410 to fix the middle and rear shell 120. The driving assembly 500 drives the middle and rear shell positioning block 420 and drives the middle and rear shell positioning block 420 to rotate.

[0060] The pad 410 supports the rear shell positioning block 420, which in turn fixes the rear shell 120. The drive assembly 500 drives the rear shell positioning block 420 to rotate, thus achieving the effect of rotating the rear shell 120. This allows the rear shell 120 to rotate, resulting in either a state where the first area 111 is exposed or a state where the first area 111 is obscured. By setting the pad 410 at an angle to the front shell positioning block 310, when the drive assembly 500 drives the rear shell positioning block 420 to abut against the pad 410, the maximum angle of rotation of the rear shell positioning block 420 is limited to prevent excessive rotation, thereby avoiding the risk of tearing the flexible circuit board. Specifically, the pad 410 and the front housing positioning block 310 are set at an angle, which means that the surface of the pad 410 facing the front housing positioning block 310 and the surface of the front housing positioning block 310 facing the pad 410 are set at an angle. This angle does not include 0°, that is, the angle can be an acute angle, a right angle, an obtuse angle or 180°.

[0061] Furthermore, such as Figure 8 As shown, the middle and rear shell positioning block 420 is provided with a third magnetic suction member 430, and the pad block 410 is provided with a fourth magnetic suction member. When the driving assembly 500 drives the middle and rear shell positioning block 420 to flip to the second position, the third magnetic suction member 430 and the fourth magnetic suction member are magnetically connected.

[0062] When the rear housing positioning block 420 is flipped to the second position, the third magnetic chuck 430 on the rear housing positioning block 420 is magnetically connected to the fourth magnetic chuck on the pad 410. This improves the stability of the rear housing positioning block 420 in the second position and prevents it from easily detaching from the pad 410 under external force. If it is necessary to detach the rear housing positioning block 420 from the pad 410 to flip it to the first position, the drive assembly 500 only needs to apply a larger driving force. This design makes it convenient and quick to operate when the rear housing fixing assembly 400 is fixed to the pad 410.

[0063] Furthermore, such as Figure 8 As shown, the middle and rear shell fixing assembly 400 further includes a clamping member 440, which is used to clamp the middle and rear shell 120 to the middle and rear shell positioning block 420.

[0064] It is understandable that when the rear shell positioning block 420 flips from the second position to the first position, the rear shell 120 on the rear shell positioning block 420 may detach from the rear shell positioning block 420 under the action of gravity. In this embodiment, by providing a clamping member 440, which is used to clamp the rear shell 120 to the rear shell positioning block 420, the risk of the rear shell 120 detaching from the rear shell positioning block 420 when it flips with the rear shell positioning block 420 is avoided. Specifically, the clamping member 440 can be a cover pressed against the rear shell positioning block 420, or the rear shell positioning block 420 can be provided with a rear shell mounting groove for installing the rear shell 120. The clamping member 440 is an elastic member, such as a silicone clamping member 440 or a rubber clamping member 440, and the clamping member 440 is clamped between the groove wall of the rear shell mounting groove and the rear shell 120.

[0065] In one embodiment, such as Figure 8 As shown, the middle and rear shell positioning block 420 has a middle and rear shell mounting groove and a connecting groove. The middle and rear shell mounting groove is used to install the middle and rear shell 120. The connecting groove connects to the middle and rear shell mounting groove. The clamping member 440 is interference-fitted with the connecting groove to hold the middle and rear shell 120.

[0066] The rear shell mounting slot is adapted to the shape of the rear shell 120 for mounting the rear shell 120. A connecting slot connects to the rear shell mounting slot and is used to mount the clamping member 440. The clamping member 440 is interference-fitted with the connecting slot, allowing it to hold the rear shell 120 in place. This ensures the rear shell 120 is securely mounted within the mounting slot, preventing it from falling off the rear shell fixing assembly 400 during rotation. When removing the rear shell 120 from the positioning assembly, the clamping member 440 is first removed from the connecting slot, and then the rear shell 120 is removed from the mounting slot. During removal, the connecting slot provides clearance for the operator, facilitating easier removal of the rear shell 120.

[0067] Furthermore, at least two connecting slots can be provided, with each slot located on opposite sides of the rear shell mounting slot. The locking member 440 within the connecting slot can simultaneously support the opposite sides of the rear shell 120 within the mounting slot, thereby improving the stability of the rear shell 120 within the mounting slot and preventing it from falling off the rear shell fixing assembly 400 during rotation. Additionally, when the rear shell 120 needs to be removed from the positioning assembly, the connecting slots on both sides of the mounting slot provide clearance for the operator to remove the rear shell 120, increasing the operating space and facilitating removal. Moreover, the operator does not need to distinguish directions; regardless of which of the two opposite connecting slots is approached, the rear shell 120 can be easily removed from the mounting slot.

[0068] Furthermore, such as Figure 8 As shown, the clamping member 440 is screwed to the middle and rear shell positioning block 420.

[0069] By connecting the clamping member 440 with the positioning block 420 of the middle and rear shell with screws, the stability of the clamping member 440 in the communicating groove is further improved, thereby improving its stability in clamping the middle and rear shell 120.

[0070] In one embodiment, please refer to the reference Figure 1 , Figure 2 and Figure 7 The drive assembly 500 includes a rotary cylinder 510 and a plug-in assembly 520. The plug-in assembly 520 is driven to the rotary cylinder 510 and is used to insert into the middle and rear shell fixing assembly 400 so that when the rotary cylinder 510 drives the plug-in assembly 520 to rotate, it causes the middle and rear shell fixing assembly 400 to flip.

[0071] The drive assembly 500 includes a rotary cylinder 510, which drives the connected components to rotate. In this embodiment, a plug-in assembly 520 is provided, which is driven to connect with the rotary cylinder 510 and is inserted into the rear shell fixing assembly 400. The rotary cylinder 510 drives the plug-in assembly 520 to rotate, thereby causing the plug-in assembly 520 to rotate the rear shell 120 assembly, thus enabling the rear shell 120 assembly to switch between a first position and a second position. This configuration achieves the effect of automatically driving the rear shell fixing assembly 400 to rotate, thereby causing the rear shell 120 to rotate, avoiding the risk of tearing the flexible circuit board or incomplete rotation that can easily occur when manually rotating the rear shell 120. In addition, the plug-in assembly 520 and the rear shell fixing assembly 400 are plugged into each other, making the plug-in assembly 520 more stable when driving the rear shell fixing assembly 400 to rotate, and preventing the rear shell fixing assembly 400 from disengaging from the drive assembly 500.

[0072] It should be noted that the structure and working principle of the rotary cylinder 510 are well known to those skilled in the art, and therefore will not be described in detail.

[0073] Specifically, please refer to the following: Figure 1 , Figure 2 and Figure 7 The insertion assembly 520 includes a finger cylinder 521, a gripper 522, and a pin 523. The finger cylinder 521 is drivenly connected to the rotary cylinder 510; the gripper 522 is drivenly connected to the finger cylinder 521; and the pin 523 is connected to the gripper 522 and is used to insert into the middle and rear shell fixing assembly 400.

[0074] With this configuration, when the pin 523 of the plug-in component 520 is inserted into the middle and rear shell fixing component 400, the gripper 522 is driven by the finger cylinder 521 to clamp the middle and rear shell fixing component 400, thereby making the middle and rear shell fixing component 400 more stable when it is flipped, and preventing the risk of the middle and rear shell fixing component 400 slipping off.

[0075] Furthermore, please refer to the following: Figure 1 , Figure 2 and Figure 7 At least two grippers 522 are provided, each gripper 522 being fixedly connected to a pin 523. The middle and rear shell fixing assembly 400 is provided with at least two insertion holes, each insertion hole containing a pin 523 and a gripper 522. Then, the finger cylinder 521 drives at least two grippers 522 to retract towards each other, clamping the middle and rear shell fixing assembly 400. Thus, the rotary cylinder 510, which is driven and connected to the finger cylinder 521, drives the finger cylinder 521, grippers 522, and middle and rear shell fixing assembly 400 to stably rotate the middle and rear shell fixing assembly 400. Based on the above-mentioned scheme that the middle and rear shell fixing assembly 400 includes a middle and rear shell positioning block 420, and the middle and rear shell positioning block 420 is rotatable, specifically, the middle and rear shell positioning block 420 is provided with an insertion hole for the pin 523 to be inserted.

[0076] Furthermore, please refer to the following: Figure 1 , Figure 2 and Figure 7 The drive assembly 500 further includes a slide cylinder 530, which is connected to the rotary cylinder 510 and can drive the rotary cylinder 510 to move along the extension direction of the plug-in assembly 520 so that the plug-in assembly 520 can be inserted into or removed from the middle and rear shell fixing assembly 400.

[0077] By configuring a slide cylinder 530, which is connected to a rotary cylinder 510, the rotary cylinder 510 is driven to move along the extension direction of the insertion assembly 520. This enables the insertion assembly 520 to be inserted into the rear housing fixing assembly 400 and to be disengaged from it. This configuration also allows the drive assembly 500 to be disengaged from the rear housing fixing assembly 400, facilitating maintenance, disassembly, or replacement of the rear housing fixing assembly 400.

[0078] Furthermore, please refer to the following: Figure 1 , Figure 2 , Figure 7 and Figure 9 The headphone housing fixing fixture also includes a positioning base plate 540, and the driving component 500 is installed on the positioning base plate 540; the positioning base plate 540 is provided with a positioning pin 541, and the base 200 is provided with a bushing 210, which is sleeved on the positioning pin 541.

[0079] This configuration allows the base 200 to be installed on and removed from the positioning base plate 540, thus enabling the front shell fixing assembly 300 and the middle and rear shell fixing assembly 400 to be connected to or disconnected from the drive assembly 500. When the base 200 is installed on the positioning base plate 540, the drive assembly 500 on the positioning base plate 540, and the front shell fixing assembly 300 and the middle and rear shell fixing assembly 400 on the base 200 can be moved and transported together. When the base 200 is removed from the positioning base plate 540, it is convenient for the operator to install the front shell 110 onto the front shell fixing assembly 300 and to install the middle and rear shell 120 onto the middle and rear shell fixing assembly 400.

[0080] The headphone housing fixing fixture also includes a positioning base plate 540, and the driving component 500 is mounted on the positioning base plate 540; furthermore, the positioning base plate 540 is magnetically connected to the base 200.

[0081] By magnetically connecting the positioning base plate 540 to the base 200, the connection between the base 200 and the positioning base plate 540 is further strengthened, preventing the base 200 from moving on the positioning base plate 540.

[0082] The present invention also proposes a dispensing device, which includes an earphone housing fixing fixture. The specific structure of the earphone housing fixing fixture is as described in the above embodiments. Since the dispensing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0083] The dispensing equipment also includes a dispensing needle, which is located above the headphone housing fixing fixture and is used to dispense adhesive onto the front shell 110 on the headphone housing fixing fixture.

[0084] This invention also proposes a dispensing method using the aforementioned headphone shell fixing fixture, please refer to the reference. Figures 1 to 6 ,as well as Figure 10 The specific structure of the headphone shell fixing fixture is as described in the above embodiments. Since this dispensing method adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0085] The dispensing method of the present invention is applied to dispensing adhesive onto an earphone housing 100, the earphone housing 100 including a front shell 110 and a middle / rear shell 120, the front shell 110 and the middle / rear shell 120 being connected by a flexible circuit board, the surface of the front shell 110 facing the middle / rear shell 120 including a first region 111 and a second region 112, the first region 111 being able to be shielded by the flexible circuit board, and the second region 112 not being shielded by the flexible circuit board; the dispensing method includes:

[0086] Step 10: Install the front shell 110 onto the front shell fixing assembly 300, and install the middle and rear shell 120 onto the middle and rear shell fixing assembly 400.

[0087] Specifically, the front shell fixing assembly 300 includes a front shell positioning block 310 and a cover plate 320. The front shell 110 fixing block may be provided with a front shell mounting groove for installing the front shell 110. The cover plate 320 can rotate relative to the front shell 110 fixing block to press the front shell 110 installed in the front shell mounting groove. The middle and rear shell fixing assembly 400 may include a middle and rear shell positioning block 420 and a clamping member 440. The middle and rear shell positioning block 420 may be provided with a middle and rear shell mounting groove for installing the middle and rear shell 120. The clamping member 440 is used to clamp the middle and rear shell 120 installed in the middle and rear shell mounting groove. The base 200, the middle and rear shell fixing assembly 400 and the front shell fixing assembly 300 mounted on the base 200 can be a combined module. When the front shell 110 and the middle and rear shell 120 are installed, the combined module can be separated from the drive assembly 500. When the drive assembly 500 drives the middle and rear shell fixing assembly 400 to flip, the combined module is then connected to the drive assembly 500.

[0088] Step 20: The drive assembly 500 drives the middle and rear shell fixing assembly 400 to flip to the first position to expose the first area 111, and applies adhesive to the first area 111.

[0089] Specifically, after the front shell 110 and the middle and rear shell 120 separate, the flexible circuit board covers a portion of the front shell 110, and the area of ​​the front shell 110 covered by the flexible circuit board is defined as the first region 111. When the driving component 500 is connected to the middle and rear shell fixing component 400, the driving component 500 can drive the middle and rear shell fixing component 400 to flip. When the driving component 500 drives the middle and rear shell fixing component 400 to flip to the first position, that is, when the front shell 110 and the middle and rear shell 120 cover each other, the flexible circuit board also flips, thereby exposing the first region 111. At this time, glue is applied to the first region 111. Specifically, the glue application process can be achieved by a glue gun.

[0090] Step 30: The drive assembly 500 drives the middle and rear shell fixing assembly 400 to flip to the second position and applies adhesive to the second area 112.

[0091] After the adhesive is applied to the front shell 110 portion of the flexible circuit board that is already covered, in order to apply adhesive to the portion of the flexible circuit board that is not covered by the front shell 110, the middle and rear shell fixing assembly 400 is driven by the driving assembly 500 to flip to the second position. When the middle and rear shell fixing assembly 400 is in the second position, the middle and rear shell 120 is separated from the front shell 110 so that the space above the second area 112 can be cleared to facilitate the application of adhesive to the second area 112.

[0092] The technical solution of this invention drives the middle and rear shell fixing component 400 through the driving component 500, and causes the middle and rear shell fixing component 400 to flip. This allows the middle and rear shell 120 on the middle and rear shell fixing component 400 to flip relative to the front shell 110 on the front shell fixing component 300, thereby causing the flexible circuit board connected between the front shell 110 and the middle and rear shell 120 to flip, exposing the first area 111. This achieves the effect of automatically flipping the middle and rear shell 120 to expose the first area 111, avoiding the risk of the flexible circuit board being torn from the earphone shell 100 due to manual flipping. It also saves manpower and improves production efficiency. Furthermore, by first driving the rear shell fixing component 400 to the first position under the drive of the drive component 500, and then driving the rear shell 120 and the flexible circuit board to flip to expose the first area 111, and applying glue to the first area 111, and then driving the rear shell fixing component 400 to the second position under the drive of the drive component 500, and applying glue to the second area 112, the risk of the flexible circuit board lifting the glue applied to the front shell 110 in the first glue application process is avoided during the second glue application process, so as to ensure that the front shell 110 and the rear shell 120 of the earphone have better sealing performance after being assembled.

[0093] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
