Description

Technical Field

[0001] The present invention relates to the field of combined processing, and in particular to a multi-part pre-assembly method and equipment, and an assembly device for an earphone suspension. Background Art

[0002] Headphones typically consist of an elastic headband and speaker units. To enhance wearer comfort, some existing headphones incorporate a suspension structure at the junction of the headband and speaker units. This suspension structure incorporates elastic elements. Compared to traditional systems where a pair of speaker units rely solely on elastic plates within the headband to open and close, the elastic force of the suspension structure with elastic elements varies more gently than that of the elastic plates. This allows for a snug fit on the wearer's head while reducing pressure on the ears.

[0003] An earphone suspension consists of a main body and multiple parts that are rotatably connected to the main body along a common axis. Conventional equipment for assembling an earphone suspension often first uses auxiliary rods to thread the multiple parts through the sub-mechanism, then positions the sub-mechanism relative to the main body. Finally, a connecting rod is used to synchronously penetrate the main body and the sub-mechanism to complete the assembly of the earphone suspension.

[0004] However, the above technology has at least the following technical problems:

[0005] The auxiliary rod needs to be installed into its jig from the first position, and after moving with the jig to the second position, it is taken by the robot and placed in the third position, and the work of inserting multiple parts to form a sub-mechanism is completed in the third position. Then the robot arm takes the sub-mechanism out from the third position and puts it into the jig again. The sub-mechanism runs with the jig to the final assembly station and is combined with the main body.

[0006] During this period, the auxiliary rods and sub-mechanisms need to be transferred multiple times, which requires the configuration of multiple robotic arms or the increase in the number of actions of a single robotic arm, resulting in increased costs or reduced efficiency. Summary of the Invention

[0007] The purpose of the present invention is to provide a multi-part pre-assembly method and equipment and an assembly device for an earphone suspension to solve the problem in the prior art that the robot arm has many movements and low assembly efficiency.

[0009] The sub-mechanism has a first clamping surface capable of being clamped by a first clamping member, and a second through hole corresponding to the first through hole is formed on one clamping end of the first clamping member;

[0010] By passing through the second through hole and the plurality of first through holes, the sub-mechanism has a second clamping surface that can be clamped by the second clamping member. The second clamping surface has a height different from the first clamping surface and has a projection on a plane perpendicular to the axis of the first through hole that does not overlap with the first through hole.

[0011] Preferably, the plurality of parts are arranged in the sub-mechanism jig so that the plurality of first through holes are on the same axis, thereby forming a sub-mechanism;

[0012] The first clamping member clamps the first clamping surface, and makes the second through hole coaxial with the first through hole for the auxiliary rod to pass through, and the other clamping end of the first clamping member serves as a limit surface for the end point of the auxiliary rod's travel;

[0013] The second clamping member clamps the second clamping surface, and synchronously releases the first clamping member to expose the first clamping surface.

[0014] A multi-part preassembly device, wherein the first clamping member and the second clamping member are both arranged in the same mechanical arm, and the first clamping member and the second clamping member have mutually perpendicular clamping movement directions.

[0015] Preferably, it includes a rod supply mechanism, and the auxiliary rod is output by the rod supply mechanism; the rod supply mechanism is placed in the running path of the robot arm, and has a second fixture and a rod supply driver, and the rod supply driver can drive the auxiliary rod to move along the inner wall of the guide groove opened on the second fixture.

[0016] Preferably, it comprises a circulating track and a circulating carrier, the rod supply mechanism is arranged on the circulating carrier, and the circulating carrier runs along the circulating track.

[0017] 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;

[0018] The feeding mechanism includes a vibrating plate, a limiting guide rail is arranged perpendicular to the discharge end of the vibrating plate, and a limiting driver is arranged in conjunction with the limiting guide rail. The part rolls along the limiting guide rail under the drive of the limiting driver; when the limiting surface is in contact with the limiting guide rail, the part maintains the current posture and falls into the tail end of the limiting guide rail.

[0019] Preferably, an assembly device for an earphone suspension is used to assemble the sub-mechanism on the main body through a connecting rod to form an earphone suspension; the main body is placed in a main body carrier, and a connecting rod carrier and an assembly driver are provided in conjunction with the main body carrier, and the connecting rod carrier and the assembly driver are arranged in a straight line on the same side of the main body carrier.

[0020] Preferably, the main body includes a first part and a second part that are hingedly arranged, the first part is rotatably connected to the sub-mechanism through a connecting rod, and the second part is obliquely inserted into the sub-mechanism in the assembly position and abuts against the sub-mechanism through an elastic member.

DETAILED DESCRIPTION

[0038] The present invention will be described in further detail below with reference to specific embodiments:

[0039] A multi-part preassembly and transplanting device is used to preassemble multiple parts into a sub-mechanism 100.

[0040] like Figure 1 and Figure 2 As shown, any part that constitutes the sub-mechanism 100 has an assembly end surface that can be attached to other parts, and any part is provided with a first through hole 110 that connects the two assembly end surfaces. When multiple parts form the sub-mechanism 100, the assembly end surfaces of different parts are tightly abutted, and the multiple first through holes 110 have the same axis.

[0041] Combine Figure 3 and Figure 4 As shown, a multi-part pre-assembly and transplanting device includes a first jig 1 and a robotic arm 2. The first jig 1 has a positioning chamber 11 corresponding to multiple part assembly positions. When multiple parts are placed in the positioning chamber 11 according to preset relative positions, a sub-mechanism 100 is formed and is grasped by the robotic arm 2.

[0042] The robotic arm 2 has a first clamping member 21, and the sub-mechanism 100 has a first clamping surface 120 that can be clamped by the first clamping member 21. In this embodiment, the first clamping surfaces 120 are provided at both ends of the sub-mechanism 100. The two clamping ends of the first clamping member 21 apply a clamping force to the first clamping surfaces 120, ensuring a tight contact between the multiple parts and enabling them to be removed from the positioning chamber 11 for transport.

[0043] In the subsequent process, the sub-mechanism 100 needs to be carried by other devices and assembled with the main body 200 to form a combination as shown in FIG. Figure 6 Therefore, the multiple parts in the sub-mechanism 100 need to maintain their relative positions without being clamped by the robot arm 2. Therefore, the present application uses an auxiliary rod 300 to penetrate the first through holes 110 of the multiple parts, thereby fixing the relative positions of the multiple parts.

[0044] Specifically, such as Figure 4 As shown, the robot arm 2 takes the sub-mechanism 100 out of the first fixture 1 and clamps it to the corresponding station of the rod feeding mechanism 3. Figure 5 As shown, the rod feeding mechanism 3 includes a second fixture 31 and a rod feeding driver 32. The auxiliary rod 300 is pre-placed in a guide groove in the second fixture 31. The guide groove is open at both ends along its length, so that the end closest to the rod feeding driver 32 can allow the actuator end of the rod feeding driver 32 to enter, and the other end can allow the auxiliary rod 300 to be separated from the second fixture 31.

[0045] The supply rod driver 32 includes a driving cylinder, and one end of the driving cylinder close to the second fixture 31 is set as an execution end. The execution end is constructed as a needle-shaped structure. Driven by the driving cylinder, it can enter the guide groove of the second fixture 31 and abut against the auxiliary rod 300 placed therein, driving the auxiliary rod 300 to pass through the other end of the guide groove.

[0046] Furthermore, in this embodiment, a circulation mechanism 4 is provided, which includes a circulation carrier 41. The rod-feeding mechanism 3 is disposed on the circulation carrier 41. The circulation carrier 41 runs along a circulation track 42, allowing the rod-feeding mechanism 3 to autonomously move to the loading station of the auxiliary rod 300. After the auxiliary rod 300 completes the loading operation, the auxiliary rod 300 is carried into the motion path of the robot arm 2. This reduces the need to transport the auxiliary rod 300, and allows the sub-mechanism 100 to be directly installed on the circulation carrier 41.

[0047] like Figure 4As shown, a second through hole 211 is provided at one clamping end of the first clamping member 21, which can correspond to the first through hole 110. When the robot arm 2 drives the sub-mechanism 100 to move to the side of the second fixture 31 away from the rod supply driver 32, the position and posture of the first clamping member 21 are adjusted so that the second through hole 211 is coaxially aligned with the guide groove. At this time, the rod supply driver 32 drives the auxiliary rod 300 to move along the guide groove, passing the auxiliary rod 300 through the second through hole 211 and the first through holes 110 of the multiple parts until one end of the auxiliary rod 300 abuts against the other clamping end of the first clamping member 21, completing the work of fixing the multiple parts through the auxiliary rod 300.

[0048] In addition, combined Figure 1 and Figure 6 As shown, at least one of the multiple parts that make up the sub-mechanism 100 has a plugged portion 130 that protrudes radially along the first through hole 110. The plugged portion 130 is used to mate with the plug-in portion 221 provided on the main body 200. Therefore, the device that supports the sub-mechanism 100 positions the sub-mechanism 100 when the plugged portion 130 and the plug-in portion 221 mate by abutting against the first clamping surface 120. Therefore, when the robot arm 2 transfers the sub-mechanism 100 to the supporting device, the first clamping surface 120 of the sub-mechanism 100 should be exposed, that is, the first clamping member 21 should be out of contact with the first clamping surface 120, so that the first clamping surface 120 can be embedded in the supporting device.

[0049] To solve this problem, combine Figure 4 As shown, the robot arm 2 is further provided with a second clamping member 22, which also has a pair of clamping ends, and the movement direction of the pair of clamping ends of the second clamping member 22 is opposite to the movement direction of the pair of clamping ends of the first clamping member 21. Figure 1 and Figure 2 As shown, the outer wall of the protruding plug-in portion 130 is constructed as a second clamping surface 140 for clamping by the second clamping member 22. The second clamping surface 140 is perpendicular to the first clamping surface 120. Because the second clamping surface 140 is arranged on the outer wall of the protruding plug-in portion 130, it is at a different height from the first clamping surface 120. When the robot arm 2 places the sub-mechanism 100 on its supporting device, the first clamping member 21 disengages from the first clamping surface 120 while the second clamping member 22 clamps on the second clamping surface 140. Under the action of the auxiliary rod 300, the multiple parts maintain their relative positions unchanged. The robot arm 2 clamps the protruding second clamping surface 140 with the second clamping member 22 to place the sub-mechanism 100 into the supporting device in the subsequent process, and the first clamping surface 120 is embedded in the supporting device to achieve positioning when the sub-mechanism 100 is assembled with the main body 200.

[0050] In addition, if Figure 7As shown, one of the parts comprising sub-mechanism 100 has planar limiting surfaces on its outer walls at both ends. When this part is assembled with other parts to form sub-mechanism 100, it is necessary to ensure that its limiting surfaces face a specific direction, such as downward. Although robotic arm 2 has the function of flipping parts during removal from its feeding mechanism, it still needs to ensure that the parts have a fixed initial posture, that is, the limiting surfaces have a fixed initial orientation.

[0051] To solve this problem, a limit rail 51 is provided at the discharge end of the part feeding mechanism, and a limit driver 52 is provided in conjunction with the limit rail 51. After the part is discharged from the vibrating plate, it enters the limit rail 51. The limit rail 51 is provided with two parallel limit surfaces corresponding to the limit surfaces at both ends of the part, supporting the two ends of the part and leaving the middle of the part suspended in the air.

[0052] The execution end of the limit driver 52 moves along the length direction of the limit guide rail 51, pushing the part on the limit guide rail 51. When the limit surface of the part is not in contact with the limit guide rail 51, the movement of the part on the limit guide rail 51 is rolling. In the process of the part rolling one circle, the limit surface will contact the limit guide rail 51. Because the limit surface and the limit guide rail 51 are both planar structures, when the limit surface contacts the limit guide rail 51, the part will stop rolling and be slid and pushed on the limit guide rail 51 by the limit driver 52 until the part is pushed to the end of the limit guide rail 51. The limit surface on the part will always remain in contact with the limit guide rail 51. Therefore, when the robot arm 2 clamps the part, the limit surface on the part has a certain initial state, which makes it easier for the robot arm 2 to flip it to the required posture according to the initial state of the limit surface.

[0053] After the sub-mechanism 100 is assembled, the second clamping member 22 on the robot arm 2 clamps the second clamping surface 140 in the sub-mechanism 100 and places the sub-mechanism 100 in the final assembly unit, where the sub-mechanism 100 and the main body 200 are assembled through the connecting rod 400.

[0054] like Figure 8As shown, the final assembly unit includes a sub-mechanism carrier 61, a main body carrier 62, a connecting rod carrier 63, and an assembly driver 64. The robot arm 2 clamps the sub-mechanism 100 and places it on the sub-mechanism carrier 61, with the spring sleeved on the plugged portion 130. The main body carrier 62 is used to carry the main body 200, and the sub-mechanism carrier 61 can move the sub-mechanism 100 from bottom to top into a relative installation position relative to the main body 200. The connecting rod carrier 63 is placed on one side of the main body carrier 62 to carry the connecting rod 400. The assembly driver 64 is arranged on the other side of the connecting rod carrier 63 relative to the main body carrier 62. The assembly driver 64, the connecting rod carrier 63, and the main body carrier 62 are arranged in a straight line, enabling the connecting rod 400 to be pushed out of the connecting rod carrier 63 and pass through the main body 200 and the sub-mechanism 100 to achieve assembly of the headphone suspension.

[0055] Specifically, a body positioning mechanism 65 is provided at the top of the body carrier 62. When the body 200 is placed onto the body carrier 62 from its feeding mechanism, the body positioning mechanism 65 abuts against the body 200, securing the body 200 in position on the body carrier 62, thereby facilitating subsequent assembly with the sub-mechanism 100. The structures of the connecting rod carrier 63 and the assembly driver 64 are similar in principle to those of the first jig 1 and the feeding rod driver 32, respectively.

[0056] In this embodiment, the main body 200 includes a first portion 210 and a second portion 220 that are rotatably connected. The plug-in portion 221 is provided on the second portion 220 and, when plugged into the plugged portion 130 of the sub-mechanism 100, can slide along its length. A third through-hole is provided on the first portion 210, and a connecting rod 400 extends through the third through-hole and the first through-hole 110 of the sub-mechanism 100, thereby achieving a rotatable connection between the sub-mechanism 100 and the main body 200. Thus, the rotatable connection between the first portion 210 and the second portion 220, the rotatable connection between the sub-mechanism 100 and the first portion 210, and the sliding connection between the sub-mechanism 100 and the second portion 220, totaling one rotatable connection and two rotatable connections, form a suspension structure between the sub-mechanism 100 and the main body 200.

[0057] like Figure 6 As shown, the rotation axis corresponding to the rotational connection between the first portion 210 and the second portion 220 is defined as the first axis, and the rotation axis between the first portion 210 and the sub-mechanism 100 is defined as the second axis. In the assembled state, the vertical end faces passing through the first axis and the second axis do not coincide, meaning that when the connecting portion 221 and the connected portion 130 are connected, they are in an inclined state.

[0058] Because the plugged portion 130 is connected to other parts via the auxiliary rod 300, if the plugged portion 130 and the plugging portion 221 are directly driven in an inclined posture to move relative to each other, the plugged portion 130 will easily rotate and sag around the auxiliary rod 300 under the action of gravity, and thus cannot achieve coaxiality with the plugging portion 221. Therefore, the plugging portion 221 and the plugged portion 130 are mated in the following way:

[0059] Combine Figure 10 As shown, during the assembly of the sub-mechanism 100 and the main body 200, to prevent the connected portion 130 from falling over, the connected portion 130 must be in a vertical position and plugged into the connecting portion 221 in the second part 220 in a vertical direction. However, in the final assembly state, the first through-hole 110 of the component in the sub-mechanism 100 must coincide with the second axis of the first part 210 to allow the connecting rod 400 to pass through. At this point, the connected portion 130 in the sub-mechanism 100 is in a tilted position.

[0060] Setting up like Figure 9 The guide mechanism 7 shown is used to fit with the part (connected portion 130) during its movement, so that the connected portion 130 forms an inclination angle in the final assembly state as described above, thereby making the first through hole 110 coincide with the second axis.

[0061] Specifically, the connected portion 130 is inserted and mated with the inserting portion 221, and the body 200 is fixed by the body positioning mechanism 65, so that the connected portion 130, driven by the sub-mechanism carrier 61, can swing about the first axis corresponding to the hinged end of the first part 210 and the second part 220. The spring-loaded abutment between the connected portion 130 and the inserting portion 221 enables longitudinal movement, thereby ensuring that the connected portion 130 maintains an angle during its swing about the first axis, so that the first through hole 110 is coaxial with the second axis.

[0062] This angle is controlled by the guide mechanism 7 .

[0063] Driven by the sub-mechanism carrier 61, the connected portion 130 is fitted into the guide wall 71 provided in the guide mechanism 7, that is, the inclination angle of the connected portion 130 is the same as the inclination angle of the guide wall 71; at this inclination angle of the connected portion 130, the first through hole 110 on the part coincides with the first axis on the first part 210.

[0064] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection 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 the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
