This is also clear in the art and will not be described in detail here.
And the driving system E is used for driving a driving mechanism E1 for sequentially switching the assembly disc A1 among the inner plugging station B, the outer cover station C and the discharging station D.
In this example, the driving mechanism E1 includes a driving shaft E10 provided at a central position of the bottom of the assembly disk a1, a stepping motor, and a transmission member for drivingly connecting the stepping motor to the driving shaft E10. This is also clear in the art and will not be described in detail here.
The transfer robot F comprises a first robot F1 which is used for grabbing and inserting the inner plug S calibrated in the inner plug station B onto the assembly seat A2, and a second robot F2 which is used for grabbing and inserting the outer cover W calibrated in the outer cover station C onto the inner plug S at the position corresponding to the outer cover station C, wherein the first robot F1 and the second robot F2 are quite common equipment, can be directly purchased from the market, and the specific structure of the first robot F1 and the second robot F2 is not explained and is quite clear and can be completely implemented.
Referring to fig. 2 again, the inside plug station B includes an inside plug feeding device B1 and an inside plug calibrating device B2, wherein the inside plug calibrating device B2 includes an inside plug calibrating platform 1, an inside plug positioning unit 2, an inside plug driving unit 3, an inside plug taking unit 4 and an inside plug negative pressure adsorption unit 5.
The inner plug positioning unit 2 comprises an inner plug positioning seat 20 which is formed with an inner plug spraying channel s2 and is in butt joint with a matching groove Q, and an inner plug shaft seat 21 which is used for connecting the inner plug positioning seat 20 on the inner plug calibration platform 1 in a way of rotating around the axis of the inner plug positioning seat 20, wherein the inner plug positioning seat 20 is cylindrical and vertically arranged, and the matching groove Q is positioned on the upper portion of the inner plug positioning seat 20.
The matching groove Q includes a center hole Q1 provided in the middle of the inner plug positioning seat 20, and a communication groove Q2 communicating with the outside from one side of the center hole Q1, wherein the hole diameter of the center hole Q1 is larger than the outer diameter of the first channel S21 and the hole depth is also larger than the length of the first channel S21, the depth of the communication groove Q2 is 2 times the thickness of the second channel S22, when the position calibration of the inner plug S is completed, the lower end of the first channel S21 is inserted into the center hole Q1, and the second channel S22 is inserted into the communication groove Q2.
In this example, there are two inside plug positioning seats 20, and the bottom is rotatably connected to the inside plug calibration platform 1 through inside plug bearings 22.
Meanwhile, the two matching grooves Q correspondingly arranged on the two inner plug positioning seats 20 are symmetrically arranged around the middle of the connecting line of the vertical centers of the two inner plug positioning seats 20.
Each inner plug positioning seat 20 comprises a cylindrical inner plug body 200 and an inner plug positioning column 201 located on the upper portion of the inner plug body 200, a matching groove Q is formed in the inner plug positioning column 201, the height of the inner plug positioning column 201 is larger than or equal to the length of an inner plug, and an inner plug shaft seat 21 is rotatably connected with the inner plug body 200 through an inner plug bearing.
Referring to fig. 3, the inside plug driving unit 3 includes an inside plug driving assembly 30 for driving the inside plug positioning seat 20 to rotate and return to the initial position for one movement cycle. That is, the rotation of the inside plug positioning seat 20 is aimed at achieving the alignment of the spraying channel s2 and the matching groove Q; the purpose of the restoration to the initial position is to unify the inner plug assembly time, the spray passage s2 in the same position.
In this example, one movement cycle of the inside plug positioning seat 20 is 2 turns, wherein one turn is forward rotation and the other turn is reverse rotation. In this case, this arrangement has the advantage that a stable abutment of the first channel and the second channel is ensured. For example, the following steps: when the second passageway misplaces with the matching groove, the formation angle is 359, 360 after it rotates the round, so synchronous rotation between the two only 1, the stability of butt joint may not be enough, consequently, in the process of the reverse rotation again for first passageway and second passageway imbed in the matching groove completely, and then ensure the accuracy of interior stopper post-calibration position.
In this embodiment, the plunger driving assembly 30 can drive the two plunger positioning seats 20 to move synchronously towards each other. In this way, a position calibration of the two internal plugs can be achieved at a time.
Specifically, the inside plug driving assembly 30 includes inside plug driving gears 300 respectively disposed on the outer peripheries of the inside plug body 200 and engaged with each other, an inside plug rack 301 engaged with any one of the inside plug driving gears 300, and a driver (not shown, but not easily conceivable) for driving the inside plug rack 301 to reciprocate along the longitudinal direction thereof.
The driver is a telescopic rod or an eccentric wheel type mechanical transmission part, and the telescopic rod can be driven in an electric, pneumatic or hydraulic mode; as for the eccentric wheel type mechanical transmission member, the conventional means in the field is adopted, but in view of implementation convenience and use cost, the telescopic rod mode is adopted in the embodiment.
As for the inside plug taking unit 4 (i.e., a robot), it includes an inside plug robot 40 that takes out the inside plugs one by one from the inside plug feeding passage and transfers them to the inside plug positioning seat 20.
In this example, the inside plug robot 40 includes an inside plug robot arm 400 movable in an X, Y, Z axis coordinate system, and an inside plug head 401 provided on the inside plug robot arm 400. In the robotic field, it is clear that the movement of the inside plug robot arm 400 in a three-dimensional coordinate system is accomplished in a conventional manner, and is also commercially available, and will not be described in detail herein.
However, it should be noted that in this embodiment, the inner plug taking head 401 includes an inner plug taking sleeve a disposed in one-to-one correspondence with the inner plug positioning seat 20, and when taking material, the inner wall of the inner plug taking sleeve a is in matching butt joint with the outer wall of the inner plug. Thus, the position calibration of the two inner plugs can be realized at one time, and the assembly efficiency of the pressing cover is improved.
Meanwhile, the inner plug taking sleeve a comprises a barrel body a1 and a polishing ring a2 arranged on the inner wall of the barrel body a1, and when taking materials, the inner wall of the polishing ring a2 is in matched butt joint with the outer wall of the inner plug. In this embodiment, in the process that the inner plug and the inner plug positioning seat 20 rotate synchronously to the initial position of the inner plug positioning seat, the excess parts (many corner burrs and the like) or the bonding objects on the surface of the inner plug can be ground, so as to be beneficial to matching with the wall surface of the outer cover.
In this example, the polishing ring a2 includes an annular polishing ring body a20 matching with the annular side surface of the inner plug S, and a polishing sheet a21 matching with the top surface of the inner plug S, wherein the polishing sheet a21 contacts with the top surface of the inner plug S in a full face contact manner, and the height of the annular polishing ring body a20 is greater than that of the inner plug S, so that the optimal polishing effect can be achieved.
As for the inner plug negative pressure adsorption unit 5, it includes a negative pressure pump 50 fixed on the inner plug positioning seat 20, an adsorption channel 51 communicating with the negative pressure pump 50 from the bottom of the matching groove Q, and a pressure release valve 52.
Specifically, the adsorption passage 51 includes a first air passage 51a extending from the bottom of the central hole q1 to the inside of the plug body 200, and a second air passage 51b for communicating the first air passage 51a with the negative pressure pump, wherein a relief valve 52 is provided on the second air passage 51 b. It should be noted that the application adopts the action of negative pressure, and mainly has two aspects, namely, when the alignment is adjusted, the downward pressure can be increased, so that the second channel can be conveniently embedded into the communicating groove; and secondly, when the inner plug and the inner plug positioning seat synchronously rotate, the downward pressure of the inner plug is increased, the destructive power of the inner plug positioning seat on the spraying channel is reduced, and the inner plug taking head is convenient to polish the periphery of the inner plug.
As shown in fig. 4 and 5, the calibration procedure of the inside plug S in this embodiment is as follows:
before calibration, the position of the matching groove Q is set, when the inner plug manipulator 40 takes out the inner plug from the feeding channel of the spiral feeder and sleeves the inner plug positioning seat 20, the first channel S21 at this time is inserted into the central hole Q1 corresponding to the matching groove Q, and the inner plug closes the matching groove Q to form a cavity, the second channel S22 has two states, namely, the first channel S22 and the second channel S2 of the matching groove Q are in normal butt joint, at this time, the inner plug S is completely erected on the inner plug positioning seat 20, under the drive of the negative pressure adsorption and inner plug driving assembly 30, after the inner plug positioning seat 20 and the inner plug synchronously rotate for 1 circle, and along with the reset of the inner plug positioning seat 20 for 1 circle, then the inner plug manipulator 40 is separated from the inner plug to complete feeding and pressure relief, and cavity pressure relief is carried out, namely, the spraying channel S2 of the inner plug is accurately calibrated to the designated position; and secondly, the second channel s22 is dislocated with the communication groove Q2 of the matching groove Q, at the moment, the second channel s22 is erected at the upper end part of the inner plug positioning seat 20, the inner plug positioning seat 20 rotates relative to the inner plug under the driving of the negative pressure adsorption and inner plug driving assembly 30, when the inner plug positioning seat 20 rotates to the position where the communication groove Q2 is aligned with the second channel s22, the inner plug material taking sleeve a is pressed down and adsorbed under the negative pressure, the second channel s22 is inserted into the communication groove Q2, and rotates synchronously to 1 circle along with the inner plug positioning seat 20, then the inner plug positioning seat 20 reversely rotates for 1 circle to reset, then the inner plug manipulator 40 is separated from the inner plug to complete feeding, and the pressure relief valve performs pressure relief on a cavity, namely, the spraying channel s2 of the inner plug is accurately calibrated to a designated position.
Meanwhile, it should be noted again that, no matter whether the matching groove Q and the spraying channel S2 are aligned accurately, the autorotation (forward 1 ring and reverse 1 ring) of the inner plug positioning seat and the formation of negative pressure are all performed normally, and meanwhile, after the inner plug S rotates synchronously with the inner plug positioning seat 20, the inner plug S and the outer cover attaching surface are polished by the polishing ring a2, and the surface surplus or residues are removed, so as to increase the matching degree of the butt joint of the inner plug S and the outer cover.
