Description

Technical Field

[0001] The present invention relates to the field of combined processing, and particularly to an assembly device and an assembly method for a headphone suspension. Background Art

[0002] A headphone generally consists of an elastic headband and a speaker unit. In the prior art, in order to improve the comfort of the wearer, some headphones are provided with a suspension structure at the connection between the headband and the speaker unit. This suspension structure has an elastic member. Compared with the traditional structure where a pair of speaker units are opened and closed only by the elastic plate inside the headband, the elastic force of the suspension structure with the elastic member changes more gently compared to that of the elastic plate. Thus, while fitting the wearer's head, the pressure on the ears is reduced.

[0003] The suspension structure is small in volume and consists of multiple parts. It is difficult for traditional automated equipment to complete the assembly of multiple parts at the same station. Therefore, in the prior art, the assembly of this product relies on manual alignment and installation of parts one by one, resulting in low efficiency. Summary of the Invention

[0004] The object of the present invention is to provide an assembly device and an assembly method for a headphone suspension to solve the problem of low efficiency in the assembly of headphone suspensions in the prior art.

[0005] The technical solution of the present invention is: an assembly device and an assembly method for a headphone suspension, which are used to assemble multiple parts and a body into one through a connecting rod passing through them. There are first through holes that are aligned and connected between the multiple parts, and a second through hole that is aligned with the first through holes is provided on the body; The assembly method includes: Passing an auxiliary rod through the multiple parts at the sub - mechanism assembly station, so that the multiple parts form a sub - mechanism that can be transferred as a whole by a pair of clamping ends; Transferring the sub - mechanism and the body to the general assembly station. The sub - mechanism is in the installation position relative to the body at the general assembly station, and the auxiliary rod has an axial movement path capable of passing through the body at the installation position; Driving the connecting rod to pass through the body and the sub - mechanism from the axial movement path, and coaxially abutting against the auxiliary rod until the auxiliary rod is ejected from the sub - mechanism.

[0006] Preferably, the body includes a first part and a second part that are hinged. The first part is rotationally connected to the sub - mechanism through a connecting rod. The second part is obliquely inserted into the sub - mechanism and abuts against the sub - mechanism through an elastic member; By configuring the sub - mechanism carrier, the sub - mechanism enters the installation position and is held in the installation position against the elastic force of the elastic member.

[0007] Preferably, the rotation axis corresponding to the hinge end of the first part and the second part is set as the first axis, and the rotation axis between the first part and the sub - mechanism is set as the second axis. In the assembled state, the vertical end faces passing through the first axis and the second axis do not coincide, and the elastic member has a first compression amount. At this time, the method for inserting the second part into the sub - mechanism is as follows: S11. In the initial state, the vertical end faces of the first axis and the second axis coincide, and the sub - mechanism and the first part are both longitudinally and coaxially arranged; S12. The sub - mechanism moves axially closer to the second part, so that the second part is inserted into the sub - mechanism, and the elastic member has a second compression amount, and the second compression amount is greater than the first compression amount; S13. The sub - mechanism moves horizontally, so that the first through - hole and the second through - hole are coaxially arranged, and simultaneously the elastic member is converted from the second compression amount to the first compression amount.

[0008] An assembly device for a headphone suspension, including a base, and the following are arranged on the base: A sub - mechanism assembly unit, having a first jig, a second jig, and a sub - mechanism assembly driver. The first jig has a first chamber for placing an auxiliary rod, the second jig has a second chamber for placing a plurality of parts, and the sub - mechanism assembly driver can drive the auxiliary rod into the second jig and penetrate through the plurality of parts; An overall assembly unit, including the sub - mechanism carrier, having an end capable of carrying the sub - mechanism; a body carrier for carrying the body; a connecting rod carrier and an assembly driver, which are linearly arranged on the same side of the body carrier.

[0009] Preferably, at least one of the parts is output by a feeding mechanism, and the outer wall of the part has a limiting surface with a planar structure; The feeding mechanism includes a vibrating disk. A limiting guide rail is arranged perpendicular to the discharging end of the vibrating disk, and a limiting driver is arranged in cooperation with the limiting guide rail. The part rolls along the limiting guide rail under the drive of the limiting driver; when the limiting surface fits the limiting guide rail, the part maintains its current posture and falls into the end of the limiting guide rail.

[0010] Preferably, a body positioning mechanism is arranged corresponding to the body carrier, and a guiding mechanism is arranged corresponding to the sub - mechanism carrier; The guiding mechanism has a guiding wall parallel to the installation direction of the sub - mechanism relative to the body. The sub - mechanism enters the installation position relative to the body by fitting the guiding wall under the drive of the sub - mechanism carrier.

[0011] Preferably, there is a feeding drive mechanism. The body carrier and the connecting rod carrier have a feeding station away from the overall assembly station under the drive of the feeding drive mechanism; In the loading station, the body, the connecting rod, and the sub-mechanism have loading spaces that can be correspondingly placed in the body carrier, the connecting rod carrier, and the sub-mechanism carrier.

[0012] Preferably, the recycling table is arranged on the opposite side of the body carrier away from the connecting rod carrier and / or the assembly driver.

[0013] Preferably, a sub-mechanism assembly positioning mechanism is provided corresponding to the second jig, which has positioning rods.

[0014] Preferably, there is a circulation mechanism. The circulation mechanism includes a circulation track placed in the middle of the base. A circulation carrier is slidably arranged on the circulation track. The auxiliary rod and the sub-mechanism are transferred to the sub-mechanism assembly station and the general assembly station through the circulation carrier; the auxiliary rod is placed into the circulation carrier from the recycling table, so as to be used for the subsequent formation of the sub-mechanism.

[0015] Compared with the prior art, the advantages of the present invention are: (1) In the present invention, the auxiliary rod penetrates through multiple parts, so that the multiple parts form an integral sub-mechanism. Thus, the assembly of the multiple parts and the body is decomposed into two steps: the assembly between the multiple parts and the assembly of the formed sub-mechanism and the body. Furthermore, the above two steps can be carried out at two independent stations, avoiding the space conflict caused by setting multiple manipulators, bins, and jigs at the same station.

[0016] (2) After the auxiliary rod is ejected by the connecting rod, it enters the circulation carrier on the circulation track through the recycling table, realizing the automatic recycling and reuse of the auxiliary rod, reducing material loss; cooperating with the loading track design of the body carrier and the connecting rod carrier, avoiding the interference of multiple motion spaces, and improving the equipment beat.

DETAILED DESCRIPTION

[0019] like Figure 2 As shown, the product assembled in the present application is composed of a plurality of parts 9, wherein a first through hole that can be aligned and connected is provided between the plurality of parts 9, a second through hole 83 aligned with the first through hole is provided on the main body 8, and a connecting rod 100 is passed through the first through hole and the second through hole 83 to realize the connection between the main body 8 and the plurality of parts 9, thereby realizing the assembly of the product.

[0020] An assembly device for earphone suspension, such as Figure 3 As shown, it comprises a base 1 on which a sub-mechanism assembly unit 2 located at a sub-mechanism assembly station and a final assembly unit 3 located at a final assembly station are arranged.

[0021] like Figure 4As shown, the sub - mechanism assembly unit 2 is used to form a sub - mechanism by passing a plurality of parts 9 through an auxiliary rod 200. It has a first fixture 21, a second fixture 22, a sub - mechanism assembly driver 23, and a sub - mechanism assembly positioning mechanism 24. The sub - mechanism assembly driver 23, the first fixture 21, and the second fixture 22 are arranged in a straight line in sequence, and the sub - mechanism assembly positioning mechanism 24 is placed on one side and is arranged corresponding to the second fixture 22.

[0022] Among them, a first chamber 211 for placing the auxiliary rod 200 is opened on the first fixture 21, and a second chamber 221 for placing a plurality of parts 9 arranged according to a preset corresponding position is opened on the second fixture 22. With the cooperation of the sub - mechanism assembly positioning mechanism 24, the positions of the plurality of parts 9 are fixed. The execution end of the sub - mechanism assembly driver 23 is configured as a thin rod, which can pass through the first chamber 211 to push the auxiliary rod 200 into the second chamber 221 and synchronously pass through the first through - holes of the plurality of parts 9, so as to form a sub - mechanism by the plurality of parts 9.

[0023] Specifically, both ends of the first chamber 211 facing the sub - mechanism assembly driver 23 and the second chamber 221 are opened for the execution end of the sub - mechanism assembly driver 23 to pass through, so that the auxiliary rod 200 can enter the second chamber 221. There are slots corresponding to a plurality of parts 9 in the second chamber 221, and the side wall facing the first chamber 211 is open - ended, and several holes are opened corresponding to the sub - mechanism assembly positioning mechanism 24. The sub - mechanism assembly positioning mechanism 24 includes a plurality of positioning rods 241. Any positioning rod 241 is driven by a positioning cylinder 242 at the tail end, so that the positioning rod 241 can pass through the holes in the second chamber 221 to tightly abut the corresponding part 9 against the side wall of the second chamber 221, thereby fixing the part 9 in the second chamber 221 and preventing the auxiliary rod 200 from failing to penetrate into the part 9 smoothly due to the shaking of the part 9 when the auxiliary rod 200 is inserted.

[0024] The general assembly unit 3 is used to assemble the sub - mechanism and the body 8 into a product, and includes Figures 5 - 7 a sub - mechanism carrier 31, a body carrier 32, a connecting rod carrier 33, and an assembly driver 34 as shown. After the sub - mechanism is taken out from the sub - mechanism assembly station by a transfer manipulator, it will be placed at the top of the sub - mechanism carrier 31, and an elastic member 300 for abutting against the second part 82 on the body 8 is installed at this position. The body carrier 32 and the connecting rod carrier 33 are respectively used to carry the body 8 and the connecting rod 100, and the assembly driver 34 is arranged on the side of the connecting rod carrier 33 away from the body carrier 32.

[0025] Specifically, a body positioning mechanism 321 is provided at the top of the body carrier 32. After the body 8 is placed on the body carrier 32 by the transfer manipulator, the body positioning mechanism 321 operates, and its execution end abuts against the top of the body 8 to fix the body 8 on the body carrier 32. Similar to the structure of the first jig 21, through holes are respectively formed at both ends of the connecting rod carrier 33 close to the body carrier 32 and the assembly driver 34 for the execution end of the assembly driver 34 to penetrate, so that the connecting rod 100 can enter the body 8 to eject the auxiliary rod 200.

[0026] Combined with Figures 7 - 9 As shown, one of the multiple parts 9 is configured as a sleeve structure 91, and the elastic member 300 is sleeved on the outer wall of the sleeve structure 91. The first part 81 on the body 8 has a plug structure 821 arranged in cooperation with the sleeve structure 91. In the assembled product, the plug structure 821 is inserted and matched with the sleeve structure 91, and the first part 81 abuts against the elastic member 300 sleeved on the outer wall of the sleeve structure 91.

[0027] It is set that the rotation axis corresponding to the hinge end of the first part 81 and the second part 82 is the first axis, and the rotation axis between the first part 81 and the sub-mechanism is the second axis. In the assembled state, the vertical end faces passing through the first axis and the second axis do not coincide, that is, when the plug structure 821 is inserted into the sleeve structure 91, the two are in an inclined state. And the elastic member 300 has a first compression amount under the abutment of the first part 81.

[0028] Since the sleeve structure 91 is connected to other parts 9 through an auxiliary shaft, if the sleeve structure 91 is directly driven to move relative to the plug structure 821 in an inclined posture, the sleeve structure 91 is likely to rotate and sag around the auxiliary shaft under the action of gravity, so that coaxiality with the plug structure 821 cannot be achieved. Therefore, the method of matching the plug structure 821 with the sleeve structure 91 at this time includes the following steps: S11. In the initial state, the vertical end faces of the first axis and the second axis coincide, so that the sleeve structure 91 and the plug structure 821 are both longitudinally and coaxially arranged.

[0029] S12. The sleeve structure 91 moves axially close to the plugging structure under the drive of the sub-mechanism carrier 31, so that the plugging structure is inserted into the sleeve structure 91, and the elastic member 300 has a second compression amount. At this time, the first through hole in the sub-mechanism is on one side of the horizontal direction of the second through hole 83 on the body 8, so the second compression amount needs to be greater than the first compression amount.

[0030] S13. The sub-mechanism carrier 31 carries the sub-mechanism to move horizontally, so that the first through hole is coaxial with the second through hole 83, and the elastic member 300 is synchronously converted from the second compression amount to the first compression amount.

[0031] Specifically, combined withFigure 9 As shown, during the assembly of the sub - mechanism and the main body 8, to prevent the sleeve structure 91 from toppling, the sleeve structure 91 needs to be inserted into the insertion rod structure 821 in the second part 82 in a vertical state along the vertical direction. However, in the final assembly state, the first through - hole of the parts in the sub - mechanism needs to coincide with the second axis on the first part 81 for the connecting rod 100 to pass through. At this time, the sleeve structure 91 in the sub - mechanism is in an inclined state.

[0032] The guiding mechanism 35 is used to fit with the part 9 (sleeve structure 91) during its movement, so that the sleeve structure forms the inclined angle in the final assembly state as described above, and further makes the first through - hole coincide with the second axis.

[0033] Specifically, the sleeve structure 91 is inserted into and cooperates with the insertion rod structure 821, and the main body 8 is fixed by the main - body positioning mechanism 321, so that the sleeve structure 91 can swing around the first axis corresponding to the hinge end of the first part 81 and the second part 82 driven by the sub - mechanism carrier 31. Combining with the spring abutment between the sleeve structure 91 and the insertion rod structure 821 enables it to move along the length direction, and further makes there be an angle during the swinging process of the sleeve structure 91 around the first axis such that the first through - hole coincides with the second axis.

[0034] This angle is controlled by the guiding mechanism 35, that is, this angle is the same as the inclination angle of the guiding wall 351.

[0035] When the sleeve structure 91 fits with the guiding wall 351 driven by the sub - mechanism carrier 31, that is, when the inclination angle of the sleeve structure 91 is the same as the inclination angle of the guiding wall 351; at this inclination angle of the sleeve structure 91, the first through - hole on the part 9 coincides with the first axis on the first part 81.

[0036] When assembling the main body 8 and the sub - mechanism, there are multiple operations including the loading operation of the main body 8, the loading operation of the sub - mechanism, the loading operation of the connecting rod 100, the assembly operation of the main body 8 and the sub - mechanism, and the assembly operation of the connecting rod 100 with the main body 8 and the sub - mechanism. Therefore, to avoid interference between the above operations in the same working station, as shown in Figure 5 and Figure 6 The main - body carrier 32 and the connecting - rod carrier 33 are both connected with a loading driving mechanism 36, and have a loading working station far from the general - assembly working station driven by the loading driving mechanism 36. The loading operations of the main body 8 and the connecting rod 100 will be carried out at the loading working station far from the general - assembly working station. Specifically, the loading driving mechanism 36 includes two loading tracks 361 laid on the base 1. The main - body carrier 32 and the connecting - rod carrier 33 are respectively slidably arranged on the two loading tracks 361, and are respectively driven by corresponding loading drivers 362 to run along the loading tracks 361.

[0037] With such a setting, only the assembly action of the sub - mechanism from bottom to top with the main body 8 and the assembly action of the connecting rod 100 penetrating the main body 8 and the sub - mechanism horizontally are carried out at the general assembly station, so that there will be no interference in the spatial position.

[0038] In the aforementioned step three, after the auxiliary rod 200 is ejected, it needs to be recycled. Therefore, in the general assembly station of this application, as Figure 6 and Figure 7 shown, a recycling table 37 is provided on the side of the main body carrier 32 away from the connecting - rod carrier 33. The ejected auxiliary rod 200 will directly enter the recycling table 37, so that it can be taken by the manipulator and placed into the circulation mechanism 5 for the subsequent formation of the sub - mechanism.

[0039] As Figure 2 shown, the circulation mechanism 5 is arranged in the middle of the base 1 and is formed into a ring - shaped structure. It includes a circulation track 51 placed in the base 1 and set as a ring - shaped mechanism. The circulation track 51 connects the sub - mechanism assembly unit 2 and the general assembly unit 3, and a circulation carrier 52 is slidably arranged on the circulation track 51. At least fixtures for carrying the auxiliary rod 200 and the sub - mechanism are provided on the circulation carrier 52. The circulation carrier 52 circulates between the sub - mechanism assembly station and the general assembly station. When the circulation carrier 52 is at the general assembly station, the auxiliary rod 200 placed on the recycling table 37 will be transported by the manipulator to the circulation carrier 52, and when the circulation carrier 52 is at the sub - mechanism assembly station, the auxiliary rod 200 will be put into the first fixture 21 by the corresponding manipulator.

[0040] In addition, this equipment also has a main - body bin 61 for storing the main body 8. The manipulator near the main - body bin 61 is used to take out the main body 8 and put it into the circulation carrier 52; a blanking bin 62 is arranged on one side of the main - body bin 61. The product formed by the assembly of the main body 8 and the sub - mechanism will be transported by the circulation carrier 52 to the blanking bin 62 for blanking. The parts 9, elastic parts 300 and connecting rods 100 are respectively output by different vibrating bowls 63.

[0041] As Figure 10 shown, one of the parts 9 constituting the sub - mechanism has a limiting surface with a planar structure on its outer wall parallel to its own axis. The limiting surfaces are respectively arranged parallel to the two ends of the part 9. When the part 9 is assembled into the sub - mechanism, it is necessary to ensure that the limiting surface faces a specific direction. Therefore, when the part 9 with such a limiting - surface structure is output from its corresponding vibrating bowl 63, its limiting surface has a definite initial orientation, so that the manipulator can flip the part 9 according to the initial orientation to make it meet the pose requirements during assembly.

[0042] To solve this problem, in the present invention, a limiting guide rail 71 is horizontally arranged at the discharging end of the vibrating disk 63 for the part 9. The limiting guide rail 71 is perpendicularly arranged in parallel to the discharging end of the vibrating disk 63 and is set as two pieces, which respectively correspond to two limiting surfaces. A limiting driver 72 is arranged at one end of a pair of limiting guide rails 71. After the part 9 is output from the discharging end of the vibrating disk 63, the limiting driver 72 drives the part 9 to roll onto the limiting guide rail 71 and continue to roll on the limiting guide rail 71. When the limiting surface on the part 9 is in contact with the limiting guide rail 71, rolling resistance will be generated on the part 9, so that the part 9 cannot roll. In this case, the limiting driver 72 will drive the part 9 to slide to the end of the limiting guide rail 71 while maintaining the current posture, so that multiple parts 9 can be grabbed by the manipulator in the same posture.

[0043] The above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
