Description

Technical Field

[0001] The utility model relates to the technical field of parts assembly equipment, in particular to a step-by-step jacking device for micro elastic parts. Background Art

[0002] At present, the earphone shaft includes a rotating seat and a rotating body, and the rotating body is rotatably connected with the rotating seat through the rotating shaft. Figure 1 As shown, a micro elastic member 2 is often inserted into the rotating seat 1, and the micro elastic member 2 abuts against the rotating shaft (not shown in the figure), so that the rotating shaft has a damping feeling during rotation. The micro elastic member 2 is generally columnar, small in size, and elastic. During the assembly of the micro elastic member 2, the micro elastic member is pushed into the rotating seat by a push-in method. Since the micro elastic member is oiled during the push-in process, the push-in mechanism will inevitably bring oil to the material tank, causing the material tank to be highly viscous, which in turn affects the loading of the micro elastic member. Utility Model Content

The diameter of the head section is smaller than that of the first ejector rod. The tapered section is a conical structure that gradually contracts toward the head section. Further, it further includes a transfer mechanism for moving the micro elastic member to the first position. When the micro elastic member carried by the transfer mechanism moves to the first position, the first ejector pin of the first ejecting mechanism pushes the micro elastic member carried by the transfer mechanism into the second guiding through hole of the movable seat.

Specific embodiments

[0030] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be more complete and comprehensive, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals in the figures denote like or similar structures, and thus their repetitive description will be omitted.

[0031] In the present utility model, the words describing the position and direction are illustrated by taking the accompanying drawings as examples, but can be changed according to needs, and all the changes made are included in the protection scope of the present utility model.

[0032] As Figure 2-15 shown, a step-by-step pushing-in device for a micro elastic member provided by the present utility model includes a first fixed seat 10 having a first guiding through hole 101, an oil injection device 40 for injecting oil into the first guiding through hole 101, a movable seat 20 having a second guiding through hole 201, a driving mechanism 70 for driving the movable seat 20 to reciprocate between a first position and a second position, a first pushing-in mechanism 50 corresponding to the first position, and a second pushing-in mechanism 60 corresponding to the second position; when the movable seat 20 moves to the first position, the first pushing-in mechanism 50 pushes the micro elastic member 2 into the second guiding through hole 201 along a first direction; when the movable seat 20 moves to the second position, the second guiding through hole 201 communicates with the first guiding through hole 101, and the second pushing-in mechanism 60 pushes the micro elastic member 2 in the second guiding through hole 201 into the first guiding through hole 101 along the first direction.

[0033] In this embodiment, referring to Figure 2-6 , before assembly, the rotating seat 1 is fixed on the jig 3, and the micro elastic member 2 is positioned on the feeding side of the movable seat 20. During assembly, the movable seat 20 is moved to the first position, and the first pushing-in mechanism 50 moves along the first direction (such as Figure 12The micro elastic member 2 is pushed into the second guiding through hole 201 of the movable seat 20 in the direction indicated by the arrow F. After that, the movable seat 20 moves to the second position. At this time, the second guiding through hole 201 of the movable seat 20 communicates with the first guiding through hole 101 of the first fixing seat 10. Meanwhile, the oil injection device 40 injects oil into the first guiding through hole 101, so that the inner wall of the first guiding through hole 101 is stained with oil. Then, the second pushing mechanism 60 pushes the micro elastic member 2 in the second guiding through hole 201 into the first guiding through hole 101 and pushes the micro elastic member 2 along the first guiding through hole 101 to be inserted into the rotating seat 1 on the fixture 3. The micro elastic member 2 is stained with oil during the process of passing through the first guiding through hole 101. And during the moving process, the side wall of the first guiding through hole 101 can play the role of smearing oil and removing excessive oil, so that the oil is smeared on the side wall of the micro elastic member 2 more evenly, avoiding uneven distribution of oil on the micro elastic member 2 or excessive residual oil.

[0034] In the present utility model, first, the first pushing mechanism 50 is used to push the micro elastic member 2 into the first guiding through hole 101 of the movable seat 20, and then the second pushing mechanism 60 is used to push the micro elastic member 2 into the rotating seat 1. Therefore, the first pushing mechanism 50 contacts less oil, which can avoid a large amount of oil being brought back to the material groove carrying the micro elastic member 2 during the retraction process of the first pushing mechanism 50, and avoid the increase in viscosity due to the presence of oil in the material groove, effectively solving the technical problem of the first pushing mechanism 50 bringing back grease during retraction.

[0035] As a preferred embodiment, refer to Figure 3 and Figure 4 The second pushing mechanism 60 includes a second ejector pin 601 and a second pushing driving member 602. The second ejector pin 601 is arranged at the output end of the second pushing driving member 602. By driving of the second pushing driving member 602, the second ejector pin 601 is driven to sequentially enter the second guiding through hole 201 and the first guiding through hole 101 forward, and to sequentially move out of the first guiding through hole 101 and the second guiding through hole 201 backward.

[0036] In this embodiment, the second ejector pin 601 is used to push the micro elastic member 2 to move in the second guiding through hole 201 and the first guiding through hole 101, which can quickly and effectively push the micro elastic member 2 into the rotating seat 1, keep the integrity of the micro elastic member 2 to the greatest extent, reduce the surface damage degree, and improve the production quality of the micro elastic member 2.

[0037] As a preferred embodiment, refer to Figure 5 and Figure 6, further comprising a second fixing seat 30 having a third guiding through hole 301, wherein the second fixing seat 30 and the first fixing seat 10 enclose a sliding channel for the sliding movement of the movable seat 20. When the movable seat 20 moves to the second position, both ends of the second guiding through hole 201 are respectively communicated with the first guiding through hole 101 and the third guiding through hole 301, and the second ejector pin 601 can enter the first guiding through hole 101 after sequentially passing through the third guiding through hole 301 and the second guiding through hole 201.

[0038] In this embodiment, by sliding the movable seat 20 in the sliding channel, it plays a guiding role in the movement of the movable seat 20. Since one end port of the third guiding through hole 301 faces the second ejecting mechanism 60, the second ejector pin 601 of the second ejecting mechanism 60 pushes the micro elastic member 2 in the second guiding through hole 201 after passing through the third guiding through hole 301, and the third guiding through hole 301 plays a guiding role in the second ejector pin 601 of the second ejecting mechanism 60.

[0039] As a preferred embodiment, refer to Figure 3 , the first ejecting mechanism 50 includes a first ejector pin 501 and a first ejecting driving member 502. The first ejector pin 501 is provided at the output end of the first ejecting driving member 502, and the first ejecting driving member 502 is used to drive the first ejector pin 501 to move forward into the second guiding through hole 201 and move backward out of the second guiding through hole 201.

[0040] In this embodiment, when the driving mechanism 70 drives the movable seat 20 to move to the first position, the movable seat 20 faces the first ejecting mechanism 50. At this time, the micro elastic member 2 is positioned on the feeding side of the movable seat 20, and the first ejecting driving member 502 drives the first ejector pin 501 to push the micro elastic member 2 forward to push the micro elastic member 2 into the second guiding through hole 201. Then, the first ejecting driving member 502 drives the first ejector pin 501 to move backward out of the second guiding through hole 201, and the driving mechanism 70 drives the movable seat 20 to move to the second position, and then the second ejecting mechanism 60 pushes the micro elastic member 2 in the second guiding through hole 201 into the first guiding through hole 101.

[0041] As a preferred embodiment, refer to Figure 13, the first ejector pin 501 includes a first ejector pin joint 5010 connected to the output end of the first ejecting driving member 502 and a first ejector rod 5011 connected to the first ejector pin joint 5010. One end of the first ejector rod 5011 away from the first ejector pin joint 5010 is provided with a tapered section 5012, and the end of the tapered section 5012 is provided with a tip section 5013. The diameter of the tip section 5013 is smaller than that of the first ejector rod 5011, and the tapered section 5012 is a conical structure that gradually contracts towards the tip section 5013.

[0042] In this embodiment, by designing the end of the first ejector pin 501 of the first ejecting mechanism 50 into a conical structure, the end of the first ejector pin 501 is prevented from contacting the movable seat 20, and the probability of the first ejector pin 501 being stained with oil is minimized.

[0043] As a preferred embodiment, refer to Figure 9-12 , further including a transfer mechanism 90 for moving the micro elastic member 2 to the first position. When the micro elastic member 2 carried by the transfer mechanism 90 moves to the first position, the first ejector pin 501 of the first ejecting mechanism 50 pushes the micro elastic member 2 carried by the transfer mechanism 90 into the second guiding through hole 201 of the movable seat 20.

[0044] In this embodiment, the transfer mechanism 90 transports the micro elastic member 2 to the first position to achieve automatic feeding. At the same time, the transfer mechanism 90 carries the micro elastic member 2, which is beneficial for the first ejector pin 501 of the first ejecting mechanism 50 to smoothly push the micro elastic member 2 into the second guiding through hole 201. It can be understood that the present utility model uses the first ejecting mechanism 50 to push the micro elastic member 2 into the movable seat 20, and the first ejecting mechanism 50 hardly contacts the oil. Therefore, the oil will not be brought back to the transfer mechanism 90 during the retraction process of the first ejecting mechanism 50.

[0045] As a preferred embodiment, refer to Figure 9-12 The transfer mechanism 90 includes a transfer plate 902 and a second driving member 903 for driving the transfer plate 902 to move between the feeding position and the first position. The transfer plate 902 is provided with a carrying groove 9020 for carrying the micro elastic member 2. When the transfer plate 902 and the movable seat 20 are both located at the first position, the carrying groove 9020 communicates with the second guiding through hole 201, and the first ejector pin 501 pushes the micro elastic member 2 from the carrying groove 9020 into the second guiding through hole 201.

[0046] In this embodiment, the micro elastic member 2 is positioned by the bearing groove 9020 on the transfer plate 902, where the shape and size of the bearing groove 9020 are adapted to the micro elastic member 2; the transfer plate 902 is driven by the second driving member 903 to ensure that the bearing groove 9020 is accurately aligned with the first ejector pin 501 of the first ejecting mechanism 50. In this way, when the transfer plate 902 and the movable seat 20 move to the first position, the bearing groove 9020 communicates with the second guiding through hole 201, and the first ejector pin 501 pushes the micro elastic member 2 from the bearing groove 9020 into the second guiding through hole 201, so as to ensure that the first ejector pin 501 can accurately and smoothly push the micro elastic member 2 into the second guiding through hole 201. Specifically, the second driving member 903 of this embodiment includes a lead screw 9030, a nut 9031 threadedly engaged with the lead screw 9030, and a motor 9033 for driving the rotation of the lead screw 9030. The transfer plate 902 is connected to the nut 9031 through a second connecting member 9032. In this way, the motor 9033 drives the lead screw 9030 to rotate, the lead screw 9030 drives the nut 9031 to move along its axis, and then drives the transfer plate 902 to reciprocate between the loading position and the first position. The transfer plate 902 is driven by the driving mode of the lead screw 9030, with good control accuracy and good stability.

[0047] As a preferred embodiment, refer to Figure 9-12 , the transfer mechanism 90 further includes a transfer fixing seat 901 having a guiding channel, and the transfer plate 902 is slidably connected in the guiding channel. The guiding channel guides the transfer plate 902 to reciprocate along a third direction, and the third direction is perpendicular to the first direction. The transfer plate 902 of this embodiment is slidably connected in the guiding channel, so that it can play a guiding role in the movement of the transfer plate 902 and ensure the reciprocating movement of the transfer plate 902 along the third direction. Among them, the third direction is as Figure 12 indicated by the arrow X.

[0048] As a preferred embodiment, refer to Figure 9-12 , the transfer fixing seat 901 is provided with a first guiding groove 9011 and a second guiding groove 9012. The bearing groove 9020, the first guiding groove 9011 and the second guiding groove 9012 all extend along the first direction. When the transfer plate 902 moves to the first position, one end of the bearing groove 9020 communicates with the first guiding groove 9011, and the other end of the bearing groove 9020 communicates with the second guiding through hole 201 through the second guiding groove 9012; the first ejector pin 501 passes through the first guiding groove 9011, the bearing groove 9020 and the second guiding groove 9012, and after pushing the micro elastic member 2 in the bearing groove 9020 through the second guiding groove 9012, it enters the movable seat 20.

[0049] In this embodiment, by providing the first guiding groove 9011 and the second guiding groove 9012, when the transfer plate 902 moves to the first position, the first guiding groove 9011 guides the first ejector pin 501 of the first ejecting mechanism 50. In this way, the first ejector pin 501 passes through the first guiding groove 9011, the bearing groove 9020, and the second guiding groove 9012, and after pushing the micro elastic member 2 in the bearing groove 9020 through the second guiding groove 9012, enters the movable seat 20.

[0050] As a preferred embodiment, referring to Figure 8-9 , it further includes a feeding mechanism 80. The transfer fixing base 901 is further provided with a receiving groove 9010 for communicating with the output end of the feeding mechanism 80. When the transfer plate 902 moves to the feeding position, the receiving groove 9010 communicates with the bearing groove 9020.

[0051] In this embodiment, by providing the receiving groove 9010 in the transfer fixing base 901, the micro elastic members 2 coming out of the feeding mechanism 80 are smoothly transmitted to the bearing groove 9020 through the receiving groove 9010, ensuring the smoothness of feeding. Specifically, the feeding mechanism 80 includes a vibrating feeder 801 and a distributing plate 802. The distributing plate 802 is used to disperse a plurality of micro elastic members 2 conveyed by the vibrating feeder 801, facilitating the simultaneous entry of the plurality of micro elastic members 2 into the bearing grooves 9020 on the transfer plate 902 and improving the feeding efficiency.

[0052] In addition, referring to Figure 6 , the driving mechanism 70 of the present utility model is preferably a cylinder. A guiding through hole 103 is provided on the side surface of the first fixing base 10. The movable seat 20 is provided with a first connecting member 202 for connecting with the piston rod of the cylinder. At least a part of the first connecting member 202 passes through the guiding through hole 103 to connect with the piston rod of the cylinder. The telescopic movement of the piston rod of the cylinder drives the movable seat 20 to move between the first position and the second position, with a simple structure and convenient control.

[0053] Among them, referring to Figure 7 , the oil injection principle of the present utility model is as follows: The first fixing base 10 is provided with an oil injection hole 102 communicating with the first guiding through hole 101 along the second direction. The oil injection end of the oil injection device 40 communicates with the oil injection hole 102 to inject oil into the first guiding through hole 101 through the oil injection hole 102, and the second direction is perpendicular to the first direction. Referring to Figure 7, the second direction is the direction indicated by the arrow Y; when the movable seat 20 moves to the second position, the second guiding through hole 201 communicates with the first guiding through hole 101, and the oil injection device 40 is started. The oil of the oil injection device 40 flows into the first guiding through hole 101 through the oil injection hole 102. Then, the second jacking mechanism 60 pushes the micro elastic member 2 in the second guiding through hole 201 into the first guiding through hole 101. During the pushing process, the micro elastic member 2 is wetted with oil. Preferably, refer to Figure 6 , the oil injection device 40 of this embodiment includes an oil injection cylinder body 401, an oil injection connecting pipe 402 and an oil injection joint 403. The oil injection joint 403 is installed on the oil injection seat and communicates with the oil injection hole 102. One end of the oil injection connecting pipe 402 is connected to the oil injection joint 403, and the other end is connected to the oil injection end of the oil injection cylinder body 401. When oil injection is required, the oil injection cylinder body 401 is started, and the oil flowing out of the oil injection cylinder body 401 flows into the first guiding through hole 101 in sequence through the oil injection connecting pipe 402, the oil injection joint 403 and the oil injection hole 102, completing the automatic oil injection process; by injecting oil into the first guiding through hole 101 through the oil injection cylinder body 401, the oil injection amount and the oil injection speed can be accurately controlled, realizing intelligent control.

[0054] It can be understood that the jig 3 of the present utility model can carry a plurality of rotating seats 1. Therefore, the first fixing seat 10 is provided with oil injection holes 102 and first guiding through holes 101 having the same number as the rotating seats 1, that is, each oil injection hole 102 is provided with an oil injection joint 403, and each oil injection joint 403 is connected with an oil injection connecting pipe 402. Correspondingly, the oil injection cylinder body 401 is provided with a plurality of oil outlet joints connected to the oil injection connecting pipes 402. In this way, only one oil injection cylinder body 401 can inject oil into a plurality of first guiding through holes 101, which is beneficial to cost saving.

[0055] In summary, through the mutual cooperation of the feeding mechanism 80, the transfer mechanism 90, the first jacking mechanism 50, the second jacking mechanism 60 and the oil injection device 40, the present utility model first uses the first jacking mechanism 50 to jack the micro elastic member 2 into the movable seat 20, and then uses the second jacking mechanism 60 to jack the micro elastic member 2 into the rotating seat 1, without grasping the micro elastic member 2 and assembling it into the rotating seat 1. The process is simple and fast, and during the process of the micro elastic member 2 passing through the first guiding through hole 101, the micro elastic member 2 can be evenly wetted with oil. In this way, the actions of oil injection, oil wiping and jacking can be completed in one stop and quickly, which greatly simplifies the assembly process of the micro elastic member 2, reduces its assembly difficulty, and greatly improves the assembly accuracy and assembly efficiency.

[0056] In addition, refer to Figure 14-15, two micro elastic members 2 need to be assembled on the rotating seat 1 of the present utility model. Therefore, the first fixing seat 10, the movable seat 20, the second fixing seat 30, the feeding mechanism 80, the transfer mechanism 90, the first jacking mechanism 50, and the second jacking and oil injection device 40 as described above are respectively provided on the left and right sides of the jig 3, so as to improve the assembly efficiency.
