Description

Technical Field

[0001] The present invention relates to the field of combined processing, and particularly to 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 pair of speaker units that only rely on the elastic plate in the headband to achieve opening and closing, 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 size 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 each part, resulting in low efficiency. Summary of the Invention

[0004] The object of the present invention is to provide 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 method for a headphone suspension, which is used to assemble multiple parts and a body into one through a connecting rod penetrating through them. There are aligned and connected first through holes between the multiple parts, and there is a second through hole on the body that is aligned with the first through hole;

[0006] [[ID=Z2]]The assembly method includes:

[0007] Pass 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;

[0008] Transfer 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 through which it can penetrate the body at the installation position;

[0009] Drive the connecting rod to penetrate the body and the sub - mechanism from the axial movement path, and abut coaxially with the auxiliary rod until the auxiliary rod is ejected from the sub - mechanism.

[0010] 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;

[0011] The sub - mechanism carrier is configured to move the sub - mechanism into the installation position and overcome the elastic force of the elastic member to maintain it at the installation position.

[0012] 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 of inserting the second part into the sub - mechanism is as follows:

[0013] 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.

[0014] 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.

[0015] S13. The sub - mechanism moves horizontally to make the first through - hole and the second through - hole coaxial, and simultaneously the elastic member is converted from the second compression amount to the first compression amount.

[0016] An assembly device for a headphone suspension, including a base, and the following are arranged on the base:

[0017] A sub - mechanism assembly unit, having a first fixture, a second fixture and a sub - mechanism assembly driver. The first fixture has a first chamber for placing an auxiliary rod, the second fixture has a second chamber for placing a plurality of parts, and the sub - mechanism assembly driver can drive the auxiliary rod into the second fixture and penetrate through the plurality of parts.

[0018] 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.

[0019] 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.

[0020] The feeding mechanism includes a vibrating bowl. A limiting guide rail is arranged perpendicular to the discharging end of the vibrating bowl, 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.

[0021] Preferably, a body positioning mechanism is provided corresponding to the body carrier, and a guiding mechanism is provided corresponding to the sub - mechanism carrier.

[0022] The guiding mechanism has a guiding wall parallel to the installation direction of the sub-mechanism relative to the main body, and the sub-mechanism fits against the guiding wall under the drive of the sub-mechanism carrier and enters the installation position relative to the main body.

[0023] Preferably, there is a loading drive mechanism, and the main body carrier and the connecting rod carrier have a loading station away from the general assembly station under the drive of the loading drive mechanism;

[0024] In the loading station, the main body, the connecting rod and the sub-mechanism have a loading space that can be correspondingly placed in the main body carrier, the connecting rod carrier and the sub-mechanism carrier.

[0025] Preferably, the recycling table is arranged on the opposite side of the main body carrier away from the connecting rod carrier and / or the assembly driver.

[0026] Preferably, a sub-mechanism assembly positioning mechanism is provided corresponding to the second fixture, which has positioning rods. The positioning rods are arranged in multiple numbers and penetrate through the second fixture to tightly press the corresponding parts against the inner wall of the second chamber.

[0027] Preferably, there is a circulating mechanism. The circulating mechanism includes a circulating track placed in the middle of the base. A circulating carrier is slidably arranged on the circulating track. The auxiliary rod and the sub-mechanism are transferred between the sub-mechanism assembly station and the general assembly station through the circulating carrier; the auxiliary rod is placed into the circulating carrier from the recycling table, so as to be used for the subsequent formation of the sub-mechanism.

[0028] Compared with the prior art, the advantages of the present invention are:

[0029] (1) In the present invention, the auxiliary rod penetrates through multiple parts, so that the multiple parts form an integral sub-mechanism, thereby decomposing the assembly of the multiple parts and the main body into two steps: the assembly between the multiple parts and the assembly of the formed sub-mechanism and the main body. Furthermore, the above two steps can be carried out at two independent stations, avoiding space conflicts caused by setting multiple manipulators, bins and fixtures at the same station.

[0030] (2) After the auxiliary rod is ejected by the connecting rod, it enters the circulating carrier on the circulating 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 main body carrier and the connecting rod carrier, avoiding multi-action space interference and improving the equipment cycle.

[0031] (3) For parts with specific orientation requirements during assembly, the present invention is provided with a limiting guide rail at the discharge end of the part. The part rolls on the limiting guide rail under the push of the limiting driver until the limiting surface on the part fits against the limiting guide rail, so that the part has an initial posture with the limiting surface facing downwards. Furthermore, the manipulator can flip the part according to the initial orientation to make it meet the pose requirements during assembly. Description of the Drawings

DETAILED DESCRIPTION

[0044] As shown Figure 2 in the figure, the product assembled in this application consists of multiple parts 9. There are first through holes that can be aligned and connected between the multiple parts 9. The main body 8 has a second through hole 83 that is aligned with the first through hole. The connection between the main body 8 and the multiple parts 9 is realized by passing a connecting rod 100 through the first through hole and the second through hole 83, thereby realizing the assembly of the product.

[0045] An assembly device for a headphone suspension, as Figure 3 shown in the figure, includes a base 1. A sub - assembly unit 2 located at the sub - mechanism assembly station and an overall assembly unit 3 located at the overall assembly station are provided on the base 1.

[0046] As Figure 4 shown in the figure, the sub - 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 jig 21, a second jig 22, a sub - mechanism assembly driver 23, and a sub - mechanism assembly positioning mechanism 24. The sub - mechanism assembly driver 23, the first jig 21, and the second jig 22 are arranged in a straight line in sequence. The sub - mechanism assembly positioning mechanism 24 is placed on one side and is arranged corresponding to the second jig 22.

[0047] Among them, a first chamber 211 for placing the auxiliary rod 200 is opened on the first jig 21. A second chamber 221 for arranging a plurality of parts 9 in a preset corresponding position is opened on the second jig 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 simultaneously 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.

[0048] 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 the plurality of parts 9 in the second chamber 221, and the side wall facing the first chamber 2l1 is open - ended and has several holes 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 passes through.

[0049] The overall assembly unit 3 is used to assemble the sub - mechanism and the main body 8 into a product, including as Figures 5 - 7The shown sub - mechanism carrier 31, body carrier 32, connecting - rod carrier 33 and assembly driver 34. After the sub - mechanism is taken out of the sub - mechanism assembly station by the 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 will be 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.

[0050] Specifically, a body positioning mechanism 321 is arranged 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 acts, 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 opened 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 through, and the connecting rod 100 can enter the body 8 to eject the auxiliary rod 200.

[0051] Combined with Figures 7 - 9 As shown, one of the multiple parts 9 is constructed 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 - rod structure 821 arranged in cooperation with the sleeve structure 91. In the assembled product, the plug - rod structure 821 is in plug - in fit 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.

[0052] Set the rotation axis corresponding to the hinge end of the first part 81 and the second part 82 as the first axis, and the rotation axis between the first part 81 and the sub - mechanism as 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 - rod structure 821 is plugged 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.

[0053] 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 - rod 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 co - axiality with the plug - rod structure 821 cannot be achieved. Therefore, the method of mating the plug - rod structure 821 with the sleeve structure 91 at this time includes the following steps:

[0054] 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 - rod structure 821 are both longitudinally and coaxially arranged.

[0055] S12. The sleeve structure 91 moves axially closer to the plugging structure driven by the sub-mechanism carrier 31, enabling the plugging structure to be inserted into the sleeve structure 91 and causing the elastic member 300 to have a second compression amount. At this time, the first through hole in the sub-mechanism is on one side of the second through hole 83 on the main body 8 in the horizontal direction. Therefore, the second compression amount needs to be greater than the first compression amount.

[0056] S13. The sub-mechanism carrier 31 carries the sub-mechanism to move horizontally, aligning the first through hole with the second through hole 83 and simultaneously converting the elastic member 300 from the second compression amount to the first compression amount.

[0057] Specifically, as shown in Figure 9 During the assembly process 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 and matched with the plug rod structure 821 in the second part 82 in the vertical direction in a vertical state. 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 penetrate. At this time, the sleeve structure 91 in the sub-mechanism is in an inclined state.

[0058] The guiding mechanism 35 is used to fit with the part 9 (sleeve structure 91) during its movement, enabling the sleeve structure to form the inclined angle in the final assembly state as described above, and further enabling the first through hole to coincide with the second axis.

[0059] Specifically, the sleeve structure 91 is inserted and matched with the plug rod structure 821, and the main body 8 is fixed by the main body positioning mechanism 321, enabling the sleeve structure 91 to 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 the spring abutment between the sleeve structure 91 and the plug rod structure 821 enables it to move along the length direction, and further enables there to 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.

[0060] 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.

[0061] When the sleeve structure 91 is driven by the sub-mechanism carrier 31 to fit with the guiding wall 351, 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.

[0062] When assembling the main body 8 and the sub-mechanism, there are multiple actions such as the loading action of the main body 8, the loading action of the sub-mechanism, the loading action of the connecting rod 100, the assembly action of the main body 8 and the sub-mechanism, and the assembly action of the connecting rod 100 with the main body 8 and the sub-mechanism. Therefore, to prevent interference between the above actions in the same working station, as shown inFigure 5 and Figure 6 As shown, both the main body carrier 32 and the connecting rod carrier 33 are connected to the loading drive mechanism 36, and under the drive of the loading drive mechanism 36, they have a loading station away from the general assembly station. The loading actions of the main body 8 and the connecting rod 100 will be carried out at the loading station away from the general assembly station. Specifically, the loading drive 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.

[0063] 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.

[0064] In the aforementioned step three, after the auxiliary rod 200 is ejected, it needs to be recycled. Therefore, in this application, at the general assembly station, as Figure 6 and Figure 7 shown, a recycling table 37 is arranged 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 put into the circulation mechanism 5 for the subsequent formation of the sub - mechanism.

[0065] As Figure 2 shown, the circulation mechanism 5 is arranged in the middle of the base 1 and forms 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. The circulation carrier 52 has at least jigs for respectively carrying the auxiliary rod 200 and the sub - mechanism. 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 jig 21 by the corresponding manipulator.

[0066] In addition, this equipment also has a main body 8 storage bin 61 for storing the main body 8. The manipulator near the main body 8 storage 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 8 storage 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, the elastic parts 300 and the connecting rods 100 are respectively output by different vibrating bowls 63.

[0067] As Figure 10As shown, one of the parts 9 that make up 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 surfaces face a specific direction. Therefore, when the part 9 with this 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 meet the pose requirements during assembly.

[0068] To solve this problem, in the present invention, a limiting guide rail 71 is arranged horizontally at the discharge end of the vibrating bowl 63 for outputting the part 9. The limiting guide rails 71 are perpendicularly arranged in parallel as two at the discharge end of the vibrating bowl 63 and respectively correspond to the two limiting surfaces. One end of a pair of limiting guide rails 71 is provided with a limiting driver 72. After the part 9 is output from the discharge end of the vibrating bowl 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 fits with the limiting guide rail 71, a 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.

[0069] The above embodiments are only for illustrating 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 features 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.
