[0042] Refer to Figures 1 to 5 , an example of the e-cigarette bottom shell assembly v involved in this patent includes a base v1 and a metal tube member v2. Taking the up-and-down direction shown Figure 1 as an example, the lower end of the metal tube member v2 is installed on the base v1, and the upper end extends out of the upper surface of the base v1. A heating element and a filter material (both not shown) are arranged inside the metal tube member v2, and a channel is arranged on the side of the metal tube member v2; as Figure 1 and 4 shown, one or more sealing grooves v20 are arranged on the metal tube member v2, and an O-ring s is assembled in the sealing groove v20. The O-ring s plays a role of sealing connection when the e-cigarette bottom shell assembly v is connected to accessories (such as an oil tank). As Figure 2 and Figure 3 shown, an electrode e1 is arranged at the lower end of the e-cigarette bottom shell assembly v. The electrodes e1 are generally installed in pairs. An electrode mounting hole v110 is arranged on the lower end surface v11 of the e-cigarette bottom shell assembly v. The electrode e1 is installed in the electrode mounting hole v110 and is electrically connected to the heating element. The electrode head e11 is exposed on the lower end surface v11 of the e-cigarette bottom shell assembly v and is used for electrical contact with a battery module (not shown). In the example shown in the drawings, one or more magnetic connection parts e2 are arranged on the lower end surface v11 of the e-cigarette bottom shell assembly v and are used for quickly adsorbing the corresponding magnetic parts of the battery module.

[0043] As Figure 2 and Figure 3 shown, the electrode e1 includes an electrode head e11 and an electrode foot e12. The electrode mounting hole v110 is configured as a stepped structure. When the electrode e1 is assembled into the electrode mounting hole v110, the electrode foot e12 is inserted into the inner hole of the electrode mounting hole v110, and the electrode head e11 is restricted on the step of the electrode mounting hole v110.

[0044] There is a filter material inside the metal tube member v2. When assembling, the filter material needs to be first wrapped around a rigid core v3 and then assembled into the metal tube member v2 as a whole. The rigid core v3 needs to be extracted in subsequent steps.

[0045] Obviously, only the e-cigarette bottom shell assembly v is described above, but the structure of the e-cigarette bottom shell assembly v is not the improvement content of this patent and belongs to the prior art.

[0046] The following describes an e-cigarette bottom shell assembly accessory assembling device applying the positioning fixture c of the present application, which involves a feeding device 1, an electrode assembling device 2, a flipping device 3, O-ring assembling devices 4 and 5, a core-pulling device 6, a discharging device 7, a turntable mechanism b, and an e-cigarette bottom shell assembly accessory assembling device.

[0048] See the appendix Figure 23 to the appendix Figure 25 , the turntable mechanism b includes a turntable platform b.1 and a turntable driving device b.2 for driving the turntable platform b.1 to rotate. Several positioning jigs c are installed at intervals along the edge of the turntable platform b.1 around the rotation axis of the turntable platform b.1, and each positioning jig c is configured with at least a first unit quantity of workpiece loading parts c0 for positioning the e-cigarette bottom shell assembly. As shown in the appendix Figure 23 to the appendix Figure 25 shown, the first unit quantity is 4, and of course it can also be a specific other quantity in other embodiments.

[0049] See the appendix Figure 20 and the appendix Figure 23 shown, the feeding device 1, the electrode assembly device 2, the flipping device 3, the O-ring assembly device 4 and the O-ring assembly device 45, the core-pulling device 6, and the blanking device 7 respectively correspond to the feeding station w1, the electrode assembly station w2, the flipping station w3, the O-ring assembly station w4, the O-ring assembly station w5, the core-pulling station w6 and the blanking station w7.

[0051] See Figures 17 to 19 , a covering part a2 is arranged on the outer periphery of the frame a, an upper layer interval a10 is formed on the upper side of the base a.1, a lower layer interval a20 is formed on the upper side of the base a.1, and the electrode assembly device 2, the flipping device 3, the O-ring assembly device 4 and the O-ring assembly device 5, the core-pulling device 6, and the blanking device 7 are installed in the upper layer interval a10; at least part of the control circuit, air source, etc. are installed in the lower layer interval a20. Of course, the control circuit, air source, etc. can also be configured outside the lower layer interval a20, such as externally, and the configuration of the air source is prior art and will not be specifically described.

[0052] At the workstations that require loading and unloading, such as the loading station w1, a loading window a.21 is provided on the side of the covering part a2; at the electrode assembly station w2, a loading window a.22 is provided on the side of the covering part a2; the O-ring assembly devices 4 and 5 are provided with a loading window a.24 on the side of the covering part a2.

[0053] See Figures 23 to 25 , the turntable drive device b.2 is an existing one. A scheme of the turntable drive device b.2 includes a driver b.21 and a transmission base b.22; the driver b.21 can adopt a motor; the turntable platform b.1 is installed on the upper side of the base a.1 through the transmission base b.22. A scheme of the transmission base b.22 is a dividing head, such as the Kader 80DT platform desktop type dividing head. The turntable platform b.1 is connected to the output end of the platform desktop type dividing head, and a center table b.3 fixedly connected to the platform desktop type dividing head is arranged in the middle of the upper side of the turntable platform b.1. The turntable drive device b.2 drives the turntable platform b.1 to rotate intermittently so as to switch each positioning jig c among various devices.

[0054] The above-mentioned electronic cigarette bottom shell assembly accessory assembly equipment is only an application embodiment of the positioning jig c of the present application, but the positioning jig c of the present application is not limited to the above application embodiment.

[0055] See Figures 6 to 16 and Figure 24 , the positioning jig c includes: a jig body c.1, clamping blocks c.2, a workpiece positioning elastic member k1, and a wedge mechanism c.4; the jig body c.1 is constructed with a first unit number of displacement slots c.10 arranged at intervals, and one side of the displacement slot c.10 is a reference wall c.11; the clamping blocks c.2 are movably assembled in each displacement slot c.10 relative to the reference wall c.11, and at least one workpiece loading portion c0 is constructed between each clamping block c.2 and the reference wall c.11; the workpiece positioning elastic member k1 acts on the clamping blocks c.2 to reset them relative to the reference wall c.11, and the wedge mechanism c.4 is arranged under the clamping blocks c.2 and is driven by a jacking driver c.3 to open the workpiece loading portion c0 to receive or release the workpiece.

[0056] Fixture body c.1, clamping block c.2, workpiece positioning elastic member k1, and wedge mechanism c.4. These components cooperate together to achieve precise workpiece positioning. The fixture body c.1 has an integral structure, which is stable and durable, ensuring long-term use and precise positioning of the fixture. The displacement slot c.10 not only provides space for the clamping block c.2 to move, but also provides a positioning reference for the workpiece through the reference wall c.11 on one side. In combination with the clamping block c.2, they can move relative to the reference wall c.11 in the displacement slot c.10 to adjust the workpiece loading part c0 to receive e-cigarette bottom shell assemblies v of a certain range of specifications. Since one side wall of the workpiece loading part c0 is the reference wall c.11, it can ensure that the workpiece is stably clamped during loading and ensure its precise position. The workpiece positioning elastic member k1 can reset relative to the reference wall c.11 after loading or unloading the workpiece, thus ensuring the reuse accuracy of the fixture. The combination of the wedge mechanism c.4 and the lifting driver c.3 facilitates the loading and unloading of the workpiece. When loading or unloading the workpiece, the lifting driver c.3 drives the wedge mechanism c.4, thereby opening the workpiece loading part c0, enabling the workpiece to be easily received or released. Through the fine design of the above structure and the coordinated work of each component, the positioning fixture c can efficiently load the e-cigarette bottom shell assembly v and ensure high positioning accuracy during loading. The positioning fixture c realizes the efficient and precise positioning of the e-cigarette bottom shell assembly v through the above structure and technical effects, further improving the automation degree and product quality of the production line. The overall design of the positioning fixture c is simple, simplifying the assembly and maintenance processes.

[0057] See Figures 6 to 9 , the fixture body c.1 and the clamping block c.2 are connected by one or more guide posts k1'. The guide posts k1' are installed on the fixture body c.1 along the relative movement direction of the clamping block c.2, and the clamping block c.2 is relatively movably assembled on the guide posts k1', such as being movably connected to the guide posts k1' through a guide sleeve k11’. The workpiece positioning elastic member k1 is installed on the guide posts k1' and acts on the clamping block c.2 to reset it towards the workpiece loading part c0 side. As Figures 6 to 9 shown in an embodiment, the workpiece positioning elastic member k1 is installed on the side of the clamping block c.2 away from the workpiece loading part c0 and acts on both the clamping block c.2 and another reference wall c.11 or the end plate c.5 of the fixture body c.1 (such as Figure 6 the rightmost workpiece positioning elastic member k1).

[0058] Attached Figures 6 to 9 In the embodiment shown, two guide posts k1' are configured and are installed on both sides of the fixture body c.1 at intervals.

[0059] See Figure 6 , 12At 15, the workpiece loading part c0 includes: a base c102 constructed on the side of the reference wall c.11 where the clamping block c.2 is located for supporting the bottom shell assembly v of the electronic cigarette, a reference positioning wall c011 constructed inside the base c102 and adapted to the shape of the base v1 of the bottom shell assembly v of the electronic cigarette, and a pressing wall c011' constructed on the clamping block c.2 and corresponding to the reference positioning wall c011. After the bottom shell assembly v of the electronic cigarette is supported and assembled into the workpiece loading part c0, when the lifting driver c.3 releases the wedge mechanism c.4, the clamping block c.2 moves towards the side of the reference wall c.11 under the action of the workpiece positioning elastic member k1, so that the pressing wall c011' presses the bottom shell assembly v of the electronic cigarette against the reference positioning wall c011 to achieve positioning. When it is necessary to take out the bottom shell assembly v of the electronic cigarette from the workpiece loading part c0, the lifting driver c.3 drives the wedge mechanism c.4 to make the clamping block c.2 move against the workpiece positioning elastic member k1, so that the pressing wall c011' disengages from the base v1 of the bottom shell assembly v of the electronic cigarette, realizing material taking.

[0060] In some embodiments, a base avoidance hole c013 for accommodating the metal tube member v2 of the bottom shell assembly v of the electronic cigarette is provided in the middle of the base c102. Thus, when the metal tube member v2 of the bottom shell assembly v of the electronic cigarette is loaded downward, the metal tube member v2 is inserted into the base avoidance hole c013, such as the loading posture of the bottom shell assembly v of the positioning fixture c between the feeding station w1 and the flipping station w3. In this way, the positioning fixture c can be applied in the accessory assembly process of the bottom shell assembly v of the electronic cigarette in both forward loading and reverse loading. As Figure 15 shown, the two bottom shell assemblies v on the left side of the positioning fixture c are loaded in reverse, and the two bottom shell assemblies v on the right side of the positioning fixture c are loaded in the forward direction. It should be noted that Figure 15 only for the convenience of explaining that the positioning fixture c of the present application can be applied in the accessory assembly process of the bottom shell assembly v of the electronic cigarette in both forward loading and reverse loading. In the same process, the loading direction of the bottom shell assembly v of the electronic cigarette is consistent.

[0061] As Figure 6 shown, at the upper end of some reference walls c.11, there are positioning holes c0' for cooperating with the positioning pins of the pressing mechanism during electrode assembly. As Figure 6 shown in the illustrated solution, there are 4 workpiece loading parts c0. Two positioning holes c0' are respectively provided at the upper ends of the 2nd and 4th reference walls c.11 from left to right.

[0062] As Figures 7 to 8, end plates c.5 are arranged at both ends of the jig body c.1. The end plates c.5 are used to fix both ends of the guide post k1'. The end plates c.5 can be fixed to both ends of the jig body c.1 through connecting parts such as screws, or one of the end plates c.5 and the jig body c.1 are of an integral structure, such as integrally processed or welded together, and the other end plate c.5 is fixed to the jig body c.1 through connecting parts such as screws.

[0063] See Figure 6 , 10 to 15, the wedge mechanism c.4 includes an arc transmission part c.42 arranged on the lower side of the clamping block c.2, and a wedge driving part c.41 for driving each arc transmission part c.42. The wedge driving part c.41 is installed on the lower side of the jig body c.1 through a driving plate c.43. A reset elastic part k2 for resetting the driving plate c.43 downward is arranged between the driving plate c.43 and the jig body c.1. When it is necessary to open the workpiece loading part c0, the driving plate c.43 is driven to move upward by the jacking driver c.3, so that the wedge driving part c.41 acts on each arc transmission part c.42, and the clamping block c.2 overcomes the workpiece positioning elastic part k1 and moves to press against the wall c011'. When the jacking driver c.3 releases the force, the driving plate c.43 moves downward under the action of the reset elastic part k2, so that the wedge driving part c.41 releases each arc transmission part c.42.

[0064] In an embodiment, arc transmission parts c.42 are provided on the lower sides of both ends of the clamping block c.2, and the wedge driving parts c.41 are arranged on the driving plate c.43 at intervals corresponding to each arc transmission part c.42. With the above structure, it can be ensured that the clamping block c.2 is balanced in force.

[0065] See Figure 6 , 9 to 14, a driving chamber c40 with a lower opening is provided on the lower side of the jig body c.1. Driving holes c.10' communicating with the displacement groove c.10 are provided in the driving chamber c40 corresponding to each arc transmission part c.42, and the wedge driving part c.41 is installed in the corresponding driving hole c.10'; the driving plate c.43 is installed in the driving chamber c40 and is restricted in the driving chamber c40 by a jig substrate c.1' connected to the lower end of the jig body c.1. The reset elastic part k2 acts between the driving plate c.43 and the top wall of the driving chamber c40. The depth of the driving chamber c40 is configured to be greater than the thickness of the driving plate c.43, so that the driving plate c.43 can have an elastic passive degree of freedom in the driving chamber c40. A driving hole c.31 communicating with the driving plate c.43 is provided in the middle of the jig substrate c.1'. The jacking driver c.3 acts on the driving plate c.43 through the driving hole c.31. The jig substrate c.1' can be connected to the lower end of the jig body c.1 through connecting parts such as screws.

[0066] In some embodiments, a guiding structure k2' is disposed between the driving board c.43 and the fixture substrate c.1'. The guiding structure k2' includes guide posts connected to the fixture substrate c.1' and guide sleeves disposed on the driving board c.43. By such an arrangement, the driving board c.43 can be laterally positioned relative to the fixture substrate c.1', enabling the driving board c.43 to move vertically smoothly.

[0067] See Figures 23 to 24 , the turntable platform b.1 is provided with lifting holes b.10 corresponding to the positions of the wedge mechanisms c.4 of the respective positioning fixtures c. The lifting driver c.3 is installed on the base a.1 corresponding to the feeding device 1, the flipping device 3, and the discharging device 7.

[0068] In the positioning fixture c corresponding to the feeding device 1, after the lifting driver c.3 drives the wedge mechanism c.4 to open the workpiece loading part c0, the feeding gripper 1.3 transfers the e-cigarette bottom shell assembly v to the workpiece loading part c0. After the lifting driver c.3 releases the wedge mechanism c.4, under the action of the workpiece positioning elastic member k1, the respective e-cigarette bottom shell assemblies v are positioned with the reference wall c.11 as the reference.

[0069] Similarly, in the positioning fixture c corresponding to the flipping device 3, the lifting driver c.3 drives the wedge mechanism c.4 to open the workpiece loading part c0. The flipping gripper 3.1 takes out the respective e-cigarette bottom shell assemblies v from the workpiece loading part c0, and the flipped e-cigarette bottom shell assemblies v are reloaded into the workpiece loading part c0 by the flipped assembly gripper 3.3. After the lifting driver c.3 releases the wedge mechanism c.4, under the action of the workpiece positioning elastic member k1, the respective e-cigarette bottom shell assemblies v are repositioned with the reference wall c.11 as the reference.

[0070] Similarly, in the positioning fixture c corresponding to the discharging device 7, the lifting driver c.3 drives the wedge mechanism c.4 to open the workpiece loading part c0, and the discharging transfer mechanism 7.4 takes out and discharges the respective e-cigarette bottom shell assemblies v from the workpiece loading part c0.

[0071] An embodiment of the lifting driver c.3 is a pneumatic driver, and its top is provided with a pressing part for driving the wedge mechanism c.4. Of course, in other embodiments, other applicable existing drivers, such as electric drivers, can also be used.
