[0013] This utility model proposes an assembly device 100. Figures 1 to 5 This is one embodiment of the present utility model.

[0014] In this embodiment of the present invention, the assembly equipment 100 is used to assemble a headset 200. The headset 200 includes a headband component 201 and an ear shell 202. The headband component 201 passes through the ear shell 202 from the outside to the inside and is movably connected to the ear shell 202. The headband component 201 has a preset locking position 203 for installing a retaining spring located on the overlapping part with the ear shell 202. The assembly equipment 100 includes a frame 1, a fixing module 2, and a first driving member 3. The fixing module 2 is disposed on the frame 1. The fixing module 2 includes a first fixing component 21 and a second fixing component 22 arranged at intervals. The first fixing component 2 and the second fixing component 2 are respectively used to fix one of the headband component 201 and the ear shell 202. The first driving member 3 is connected to the first fixing component 21 and is used to drive the first fixing component 21 to move closer to the second fixing component 22 so that the preset locking position 203 is exposed in the ear shell 202.

[0015] In the implementation of the technical solution of this utility model, the first driving component 3 drives the first fixing component 21 to move closer to the second fixing component 22, so that the headband component 201 and the ear shell 202, which are respectively fixed to the first fixing component 21 and the second fixing component 22, move relative to each other, thereby compressing the spring used for pre-tensioning, so that the preset locking position 203, which was originally located at the overlapping position of the ear shell 202 and the headband component 201, is exposed. The worker can further install the retaining spring on the preset locking position 203. The assembly process of the headphone 200 can be replaced by automatic assembly by the driving equipment, which simplifies the assembly process of the headphone 200, improves production efficiency, reduces human fatigue, and ensures production safety.

[0016] In one embodiment, such as Figure 2As shown, the assembly equipment 100 also includes a pressing module 4 disposed on the frame 1. The pressing module 4 includes a first pressing head 41 and a second driving member 42. The second driving member 42 is connected to the first pressing head 41 and can drive the first pressing head 41 to move. The first pressing head 41 is used to press the retaining ring onto the preset locking position 203. After the preset locking position 203 is exposed, the retaining ring is pre-installed in the preset locking position 203 manually. Then, the assembly equipment 100 is started so that the second driving member 42 drives the first pressing head 41 to press down, thereby completing the installation of the retaining ring on the preset locking position 203. Compared with the traditional manual installation of retaining rings, this not only avoids problems such as misalignment and incomplete locking caused by uneven force, but also saves the operation steps of manual force application, further reducing the intervention of assembly personnel. At the same time, it makes the retaining ring pressing process more standardized, which not only improves the assembly efficiency of a single machine, but also ensures the consistency and yield rate of the connection and fixation between the headband component 201 and the ear shell 202.

[0017] From the perspective of improving the ease of operation of the assembly equipment 100 and the safety of the operators.

[0018] In one embodiment, such as Figure 2 As shown, the assembly equipment 100 also includes a third driving component 5; the third driving component 5 is disposed on the frame 1 and connected to the fixing module 2. The fixing module 2 has a loading position and a pressing position. The third driving component 5 can drive the fixing module 2 to move to the loading position and the pressing position. The third driving component 5 can drive the fixing module 2 to the loading position, which is closer to the operation port, allowing workers to more easily pre-install the retaining ring on the preset slot 203. After pre-installation, the fixing module 2 is then driven by the third driving component 5 to move to the pressing position, where the pressing module 4 presses and installs the retaining ring. This provides convenience for workers to load materials and avoids workers from excessively entering the equipment, reducing safety risks during the production and assembly process.

[0019] It should be noted that the first fixing component 21 can specifically fix either the headband component 201 or the ear shell 202. That is, whether the headband component 201 moves closer to the ear shell 202 or the ear shell 202 moves closer to the headband component 201, it will not affect the normal progress of the production process. However, since only the part of the headband component 201 closest to the ear shell 202 is fixed, in order to further ensure the product safety of the headband component 201, it may be necessary to provide limiting support for other parts.

[0020] Based on the above analysis, in one embodiment, the first fixing component 21 is used to fix the ear shell 202.

[0021] In one embodiment, such as Figure 4 As shown, the assembly equipment 100 also includes a support structure 6; the support structure 6 is disposed on the frame 1 and forms a support platform, the support platform being used to support the portion of the headband assembly 201 away from the ear shell 202. The support platform supports the suspended portion of the headband assembly 201, preventing the ear shell 202 assembly from breaking or other accidents during assembly.

[0022] The specific structure of the support structure 6 is not limited, as long as it can achieve the support effect for the head-mounted component 201 and does not hinder the normal assembly. In a further embodiment, the support structure 6 forms a limiting groove, with the two side walls of the limiting groove being through to allow the head-mounted component 201 to pass through. Part of the structure of the head-mounted component 201 is supported by the bottom of the limiting groove and is limited by a pair of side walls of the limiting groove that are not penetrated.

[0023] To specifically achieve the fixation of the first fixing component 21 on the ear shell 202, in one embodiment, as follows: Figure 3 As shown, the first fixing component 21 includes a positioning block 211 and a second pressing head 212. The positioning block 211 forms a positioning groove. The first driving component 3 is connected to the second pressing head 212 and can drive the second pressing head 212 to move into the positioning groove. This solution uses the positioning groove to initially position the ear shell 202, and then uses the second pressing head 212 to press and fix the ear shell 202 in the positioning groove, thereby fixing the ear shell 202. This solves the problem of the ear shell 202 easily shaking when manually held, and ensures the consistency of the position of the ear shell 202 each time it is fixed. It provides a precise benchmark for the subsequent docking of the headband component 201 and the ear shell 202, spring compression, and snap ring pressing, further improving the accuracy and stability of the entire assembly process and reducing assembly defects caused by the fixing deviation of the ear shell 202.

[0024] In one embodiment, the second pressure head 212 has a clearance groove; the opening of the clearance groove is located at one end of the second pressure head 212 facing the positioning groove, and the clearance groove extends away from the positioning groove. The clearance groove is a protruding structure on the ear shell 202, such as an interface, a reinforcing rib, or a reserved space for the headband assembly 201 to be inserted into the ear shell 202. When the second pressure head 212 extends into the positioning groove to press the ear shell 202, these components that are prone to colliding with the second pressure head 212 will be embedded in the clearance groove, avoiding being squeezed and damaged by the second pressure head 212. This protects the structural integrity of the ear shell 202 and the headband assembly 201, reduces assembly defects caused by component collisions, and further improves the compatibility and assembly accuracy of the fixing mechanism.

[0025] In one embodiment, such as Figure 3 As shown, the second fixing component 22 is used to fix the headband component 201. The second fixing component 22 includes a fourth driving member 221 and two clamping blocks 222. The fourth driving member 221 is connected to at least one of the clamping blocks 222 and can drive at least one of the clamping blocks 222 to move closer to or away from the other clamping block 222. During assembly, part of the structure of the headband component 201 is located between the two clamping blocks 222. The fourth driving member 221 drives the two clamping blocks 222 to move closer to each other to form a clamping and fixing of the headband component 201. Compared with manual hand-holding or single pressure head fixing, not only is the clamping force more stable and the fixing position more accurate, but the standardized movement of the driving member can also ensure that the state of fixing the headband component 201 is consistent each time.

[0026] In a further embodiment, the clamping blocks 222 have receiving grooves on opposite sides, and the openings of the two receiving grooves are arranged opposite each other. When clamping the headband assembly 201, the headband assembly 201 is limited and clamped within the space formed by the combination of the two receiving grooves, which further improves the assembly accuracy and reduces the possibility of the headband assembly 201 being damaged by clamping.

[0027] The specific fixing form of the second fixing component 22 is not limited. In one embodiment, the second fixing component 22 can be a locking block. The locking block has a slot and a latch that can open and close the slot. The headband component 201 is pre-installed in the slot and locked in the slot by the latch.

[0028] In one embodiment, such as Figure 5 As shown, the fixing module 2 includes two first fixing components 21 and two second fixing components 22. Generally, the headband component 201 of the headphones 200 is connected to an ear shell 202 at both ends. By setting two first fixing components 21 and two second fixing components 22, the assembly process of the retaining springs of two different ear shells 202 of the same headphones can be performed simultaneously, which greatly improves the assembly efficiency.

[0029] In one embodiment, the assembly equipment 100 further includes a control module, which includes an integrated control center and operation keys 7. The integrated control center is electrically connected to the first drive component 3 and the operation keys 7, respectively. This allows the operation keys 7 to initiate the processes of each part, ensuring that they operate independently and in an orderly manner.

[0030] The specific driving structure of the first driving component 3, the second driving component 42, the third driving component 5, and the fourth driving component 221 is not limited and can be electric drive, mechanical drive, etc.

[0031] In one embodiment, the first driving component 3, the second driving component 42, the third driving component 5, and the fourth driving component 221 can all be cylinders. Each cylinder uses the same air supply system, eliminating the need to configure air compressors, dryers, and other air source equipment for each cylinder separately. This reduces pipeline laying and the number of components, making the system more compact. Multiple cylinders can achieve synchronous operation or work collaboratively according to preset logic, improving the operating accuracy of the equipment.

[0032] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
