[0033] Please refer to Figure 1 Figure 9 The embodiment provides a three-pin regulation mechanism, which is applied to regulating three pins 2 of an electronic cigarette semi-finished product 1, the semi-finished product 1 comprises a support pipe, a cotton rod, an auxiliary rod and a heating mesh, and the three pins 2 are arranged on the heating mesh; the three-pin regulation mechanism comprises:

[0034] A clamping and positioning assembly 4 is used for clamping and positioning the semi-finished product 1.

[0035] Specifically, the clamping and positioning assembly 4 clamps the semi-finished product 1 without affecting the extension of the three pins 2 at one end.

[0036] A first adjusting assembly 5 is used for adjusting the position of the end of the three pins 2 to a first predetermined position.

[0037] In some embodiments, the first adjusting assembly 5 is used for adjusting the position of each pin in the three pins 2 in the horizontal direction, and the distribution interval of the three through holes 310 on the connecting plug 3 is smaller than the interval between the pins in the three pins 2 under normal circumstances.

[0038] A second adjusting assembly 6 is used for adjusting the position of the connection between the three pins 2 and the support pipe of the semi-finished product 1 to a second predetermined position.

[0039] The position of the connection between the three pins 2 and the support pipe of the semi-finished product 1 can also be referred to as the root of the three pins 2 exposed from the support pipe. In some embodiments, the second adjusting assembly 6 is used for adjusting the position of each pin in the three pins 2 in the vertical direction.

[0040] A displacement device 7 is used for driving the second adjusting assembly 6, so that the adjusting end of the second adjusting assembly 6 moves relative to the adjusting end of the first adjusting assembly 5.

[0041] ​In some embodiments, the three-pin regular mechanism comprises a rack 9, the shifting device 7 comprises a linear cylinder mounted on the rack 9, a sliding rail mounted on the rack 9, and a sliding seat in sliding connection with the sliding rail. The piston rod of the linear cylinder is connected with the sliding seat, and the second adjusting assembly 6 is connected with the sliding seat.

[0042] It is easily conceivable that the linear cylinder can be replaced by other devices capable of providing linear reciprocating movement.

[0043] Please refer to Figure 4 and Figure 9 , the clamping and positioning assembly 4 comprises a positioning template 410 provided with a clamping and positioning groove 411 corresponding to the semi-finished product 1; the clamping and positioning groove 411 is provided with an opening for the three pins 2 of one end of the semi-finished product 1 to extend out.

[0044] In some embodiments, the clamping and positioning groove 411 clamps part of the outer wall of the support tube of the semi-finished product 1 and part of the auxiliary rod.

[0045] Please refer to Figure 4 and Figure 9 , the clamping and positioning assembly 4 comprises a first pair of clamping devices 420, and a pair of first clamping arms 430 mounted on the power output end of the first pair of clamping devices 420; the two first clamping arms 430 are respectively distributed on both sides of the positioning template 410; the first pair of clamping devices 420 is used to drive the two first clamping arms 430 to approach or separate; when the first pair of clamping devices 420 drives a pair of first clamping arms 430 to clamp, the outer wall of the support tube is clamped and fixed.

[0046] In some embodiments, the first pair of clamping devices 420 is a finger cylinder, and other devices in the prior art with the same output power movement as the finger cylinder can also be used.

[0047] A pair of first clamping arms 430 driven by the first pair of clamping devices 420 provides active power to clamp and fix the remaining part of the support tube of the semi-finished product 1 not clamped by the clamping and positioning groove 411.

[0048] Please refer to Figure 9 , the clamping head of the first clamping arm 430 is provided with a simulated arc surface 431 corresponding to the outer wall of the support tube, and a clamping part 432 corresponding to the cotton strip extending out of the support tube.

[0049] This design prevents the semi-finished product 1 from being pinched.

[0050] The clamping head of the first clamping arm 430 does not completely surround the outer periphery of the support tube, because the cotton strip of the semi-finished product 1 also has a part extending out of the support tube, and the cotton strip, the heating mesh and the support tube inside the support tube are not fixedly matched with the support tube, but relatively move when subjected to external force.

[0051] In order to avoid the dislocation of the cotton and the heating mesh relative to the support tube when the connecting plug 3 is connected with the three pins 2 and the support tube, and to avoid the production of defective products, the clamping part 432 is used to clamp the cotton extending from the support tube. The arc surface 431 of the clamping head of the clamping part 432 clamps the at least partially arc-shaped outer wall of the support tube, and the cotton is clamped by the clamping part 432. In this clamping state, the production quality is improved.

[0052] In some embodiments, the clamping part 432 is a flat structure.

[0053] Specifically, in addition to being used for clamping and positioning the semi-finished product 1, the clamping and positioning assembly 4 is mainly used for clamping the cotton extending from the support tube. When the three pins 2 are inserted through the three insertion holes 310 of the connecting plug 3, the internal components of the semi-finished product 1 will not move. During the insertion of the three pins 2 through the three insertion holes 310 of the connecting plug 3, the pins will be subjected to friction, and the pins will be subjected to force, which will cause the heating mesh to be displaced. Since the heating mesh and the cotton are highly attached in the semi-finished product 1, and the heating mesh and the cotton are wrapped around the auxiliary rod, if the cotton is not fixed, the internal components of the support tube will be undesirably moved in the direction of the force. Therefore, the cotton is clamped by the clamping part 432, so that the cotton is not moved, the heating mesh is not moved, and the connecting plug 3 and the semi-finished product 1 are successfully assembled.

[0054] Please refer to Figure 5 and Figure 6 The first adjusting assembly 5 includes a second pair of clamping devices 510 and a pair of second clamping arms 520 mounted on the power output end of the second pair of clamping devices 510. The second pair of clamping devices 510 is used to drive the two second clamping arms 520 to approach or separate. The clamping head of the second clamping arm 520 is provided with a stepped groove 521 matched with the distribution of the three pins 2.

[0055] In some embodiments, the second pair of clamping devices 510 is a finger air cylinder, and other devices with the same output power movement as the finger air cylinder can also be used.

[0056] The stepped groove 521 divides the clamping head of the second clamping arm 520 into two vertical walls. The upper vertical walls correspond to the left and right pins at the upper end, and the lower vertical wall corresponds to the pin at the lower end. When the two second clamping arms 520 approach, the pin at the lower end is finally pushed and clamped by the left and right vertical walls, and the clamping force does not affect the subsequent movement of the pin by the second adjusting assembly 6. The left and right pins are pushed by the vertical walls of the left and right clamping heads. The second pair of clamping devices 510 drives the pair of second clamping arms 520 to approach to the limit position, and the end of the three pins 2 is displaced to the first predetermined position.

[0057] The design of the stepped groove 521 is mainly to make the vertical wall of the upper end of the clamp head of the second clamp arm 520 longer in length. In actual production scenarios, the bending angle of the three pins 2 before trimming is random. Only when the clamp head of the second clamp arm 520 is designed to be long enough in the length direction without interfering with other components, can the range of possible bending of the left and right pins be covered when the clamp heads of the two second clamp arms 520 are closed.

[0058] Please refer to Figure 7 and Figure 8 The second adjusting assembly 6 includes a third pair of clamping devices 610 and a pair of third clamp arms 620 mounted on the power output end of the third pair of clamping devices 610. The third pair of clamping devices 610 are used to drive the two third clamp arms 620 to close or separate. The clamp head of the third clamp arm 620 is provided with a guide slope 621 and a receiving groove 622 at the end of the guide slope 621. The receiving groove 622 corresponds to the outer diameter of the pins in the three pins 2.

[0059] In some embodiments, the third pair of clamping devices 610 is a finger air cylinder, and other devices with the same output power movement as the finger air cylinder can also be used.

[0060] Preferably, after the receiving groove 622 receives the pins, they are in a clearance fit relationship.

[0061] In some embodiments, the second adjusting assembly 6 not only pushes the roots of the three pins 2 horizontally, but also pushes them vertically, so that each pin can smoothly fall into the three receiving grooves 622 by relying on the guidance of the guide slope 621.

[0062] First, trim the three pins 2 horizontally by the first adjusting assembly 5, and then trim them vertically. This can avoid the deformation of the pins in the horizontal direction, which exceeds the trimming range of the clamp and causes the failure of the vertical trimming clamp.

[0063] When the third pair of clamping devices 610 drive a pair of third clamp arms 620 to close to the limit position, the ends of the three pins 2 are displaced to the second predetermined position.

[0064] The clamp head of the pair of second clamp arms 520 is also the adjusting end of the second adjusting assembly 6. The clamp head of the pair of first clamp arms 430 is also the adjusting end of the first adjusting assembly 5.

[0065] Please refer to Figure 7 and Figure 8The third clamping arm 620 is provided with a pair of insertion plates 623, and the guide slope 621 and the accommodating groove 622 are arranged on the pair of insertion plates 623; the third clamping arm 620 is provided with a pair of insertion grooves 624 corresponding to the pair of insertion plates 623, and the third clamping arm 620 is provided with an enclosing plate 625; when the pair of third clamping arms 620 are closed, the enclosing plate 625 closes the accommodating grooves 622 on the pair of insertion plates 623; the side of the pair of insertion plates 623 closes the accommodating grooves 622 on the third clamping arm 620.

[0066] The side of the pair of insertion plates 623 and the enclosing plate 625 can well close the outlet of the accommodating groove 622, and the pin does not come off the accommodating groove 622 during the process that the displacement device 7 drives the second adjusting assembly 6 to move close to the first adjusting assembly 5.

[0067] Please refer to Figure 2 and Figure 3 , Figure 7 and Figure 8 , the three pins 2 adjusted by the first adjusting assembly 5 are arranged in two groups in the vertical direction, and the upper end group is two pins which are horizontally flush; the lower end group is one pin which is horizontally located between the two pins of the upper end group; the two third clamping arms 620 are distributed vertically, and the guide slope 621 and the accommodating groove 622 of the upper third clamping arm 620 are separated by the enclosing plate 625; the pair of insertion plates 623 are arranged on the third clamping arm 620.

[0068] This layout also corresponds to the distribution of the penetrating holes 310 of the connecting plug 3.

[0069] Please refer to Figure 4 and Figure 5 , the avoidance driving device 8 is installed on the power output end of the displacement device 7; the second adjusting assembly 6 is installed on the power output end of the avoidance driving device 8; the avoidance driving device 8 is used to drive the second adjusting assembly 6 to move relative to the side of the clamping and positioning assembly 4.

[0070] Since the position of the clamping head of the pair of first clamping arms 430 corresponds to the end of the three pins 2, after the finger cylinder drives the pair of first clamping arms 430 to separate, the semi-finished product 1 can be avoided, and the semi-finished product 1 can be taken out of the clamping and positioning groove 411 without affecting the taking and placing. The arrangement mode of the second adjusting assembly 6 is that the two third clamping arms 620 are vertically distributed, which will affect the feeding and discharging of the semi-finished product 1, and the three pins 2 will conflict with the third clamping arms 620.

[0071] Therefore, by setting the avoidance driving device 8, the second adjusting assembly 6 is driven to move, and the whole moves away from the side of the clamping positioning assembly 4, so as not to affect the feeding and discharging of the semi-finished product 1.

[0072] In some embodiments, the avoidance driving device 8 includes a connecting seat connected with the sliding seat, a guide rail provided on the connecting seat, a sliding block in sliding connection with the guide rail, a linear cylinder mounted on the connecting seat, and a mounting seat connected with the sliding block. The telescopic rod of the linear cylinder is connected with the sliding block. The finger cylinder of the second adjusting assembly 6 is mounted on the mounting seat.

[0073] In some embodiments, the positioning template 410 is provided with a side through hole (not shown).

[0074] After the semi-finished product 1 is placed into the clamping positioning groove 411, the side through hole is located below the semi-finished product 1.

[0075] In some embodiments, the feeding and discharging of the semi-finished product 1 is realized by an automatic device. The material taking part of the automatic device passes through the side through hole, and then clamps the semi-finished product 1 and moves to the next station.

[0076] The working principle of the three-pin straightening mechanism is as follows:

[0077] In the initial state, the linear cylinder piston rod of the displacement device 7 is in the retracted state, the third clamping arm 620 of the second adjusting assembly 6 is away from the clamping head of the second clamping arm 520. The first pair of clamping devices 420 drive a pair of first clamping arms 430 to be in the open state. The linear cylinder of the avoidance driving device 8 drives the second adjusting assembly 6 to be away from the side of the positioning template 410. The second pair of clamping devices 510 of the first adjusting assembly 5 drive a pair of second clamping arms 520 to be in the open state. The third pair of clamping devices 610 of the second adjusting assembly 6 drive a pair of third clamping arms 620 to be in the open state.

[0078] Then, the semi-finished product 1 raw material is placed into the clamping positioning groove 411 by manual or automatic device, and the first pair of clamping devices 420 are controlled to drive a pair of first clamping arms 430 to close, and the semi-finished product 1 is further clamped and positioned and fixed.

[0079] The second pair of clamping devices 510 drive a pair of second clamping arms 520 to close, and adjust the position of the horizontal direction of the three pins 2 end portions.

[0080] Under the driving of the linear cylinder of the avoidance driving device 8, the second adjusting assembly 6 as a whole approaches the side of the positioning template 410, and finally the two clamping heads of the pair of third clamping arms 620 in the open state are located on the upper and lower sides of the three pins 2. The third pair of clamping devices 610 drive a pair of third clamping arms 620 to close, and complete the further adjustment of the vertical direction and the horizontal direction of the three pins 2.

[0081] Then, in the straight-line cylinder piston rod of the shifting device 7 is in the state of extension, the displacement driving device 8, the second adjusting assembly 6 moves as a whole, under the combing of the closed containing groove 622, the three pins 2 are deformed, finally the chuck of the third clamping arm 620 is adjacent to the chuck of the second clamping arm 520, and the three pins 2 extending from the support pipe are regularly shaped as a whole, and the three pins 2 correspond to the three through holes 310 on the connecting plug 3.

[0082] The second adjusting assembly 6 is first regularized at the root of the three pins 2, and then moves from the root to the end, which is based on the experience that the deformation of the pins at the root is small and the regularizing difficulty is small.

[0083] Under the operation of the feeding assembly component (not shown) of the connecting plug 3, the connecting plug 3 is pushed, so that the three pins 2 are partially inserted into the three through holes 310, and then the three pins 2 are deformed under the adjustment of the first adjusting assembly 5, the second adjusting assembly 6 and the displacement driving device 8, and the three pins 2 are deformed, and the three pins 2 are further pushed into the three through holes 310 and the connecting plug 3 is connected with the support pipe under the operation of the feeding assembly component of the connecting plug 3, so that the three pins 2 are inserted into the three through holes 310 and the connecting plug 3 is connected with the support pipe, and one assembly is completed.

[0084] Finally, the first pair of clamping devices 420 drive a pair of first clamping arms 430 to cancel the clamping of the semi-finished product 1.

[0085] In summary, the automatic regularizing mechanism provided by the present application has stable regularizing quality for the three pins 2, improves production efficiency, and solves the problem of high labor intensity.
