Description

Technical Field

[0001] The utility model belongs to the technical field of electronic cigarette manufacturing, and in particular relates to a core pulling device for an electronic cigarette bottom shell assembly. Background Art

[0002] The electronic cigarette bottom shell assembly involved in this patent includes a base and a metal tube component. The lower end of the metal tube component is installed on the base, and the upper end extends out of the upper surface of the base. The metal tube component is configured with a heating element and a filter material inside. During assembly, the filter material needs to be wrapped into a rigid core first, and then assembled as a whole into the metal tube component. The rigid core serves as an auxiliary component and needs to be extracted after assembly is completed.

[0003] In the prior art, workers have to extract the core, which results in low work efficiency. Some manufacturers have designed automatic extraction equipment to extract the rigid core. However, since the rigid core and the metal tube component are clamped by the filter material, the adhesion is large, and the metal tube component is easily deformed or loosened during extraction, so it cannot be widely used. Summary of the invention

[0004] The utility model aims to solve the problems in the prior art of low efficiency of workers in extracting the rigid core of the bottom shell assembly of an electronic cigarette, and mechanical extraction easily causing deformation or loosening of the metal pipe component under stress.

[0005] This patent adopts the following technical solutions:

[0006] The core-pulling device of the bottom shell assembly of an electronic cigarette comprises: a presser, a plurality of rigid core clamps and a core-pulling driving mechanism; the presser comprises a presser piece for pressing the bottom shell assembly of an electronic cigarette loaded with a positioning jig and having a core-pulling channel penetrating the upper and lower surfaces for inserting a metal tube component and for the rigid core to pass through the upper surface, and a presser driving mechanism for driving the presser piece to press against or away from the bottom shell assembly of the electronic cigarette; a plurality of rigid core clamps clamp the rigid core in the metal tube component of the bottom shell assembly of the electronic cigarette from the upper side of the presser piece; and a core-pulling driving mechanism for driving the rigid core clamp to pull the rigid core out of the bottom shell assembly of the electronic cigarette.

[0007] The electronic cigarette bottom shell assembly core extraction device of this patent is equipped with a presser. When extracting the rigid core, the presser presses against the electronic cigarette bottom shell assembly, and the rigid core passes through the upper surface of the presser through the core extraction channel. When the rigid core clamp extracts the rigid core, the presser restricts the electronic cigarette bottom shell assembly and the metal tube component, which can avoid the metal tube component from being deformed or loosened due to stress when extracting the rigid core.

[0008] Furthermore, the material presser also includes a material press connection seat, the material press piece is connected to the lower side of the material press connection seat through a plurality of elastic buffer connection pieces, and the material press connection seat is connected to the driving part of the material press drive mechanism. The elastic buffer connection piece acts between the material press piece and the material press connection seat, so that the pressing between the material press piece and the bottom shell assembly of the electronic cigarette has a passive degree of freedom, thereby avoiding damage to the bottom shell assembly of the electronic cigarette caused by the hard pressing of the material press piece.

[0009] Furthermore, the pressing piece is provided with a plurality of first connection holes, and the pressing connection seat is correspondingly provided with a plurality of second connection holes, and the elastic buffer connection piece includes a bolt and a spring, the spring is installed between the first connection hole and the second connection hole, and the bolt connects the first connection hole and the second connection hole, so that the spring elastically acts on the pressing piece and the pressing connection seat. The elastic buffer connection piece adopting the above structure has a simple structure, and the spring sleeved on the bolt can ensure that it will not separate from the pressing piece and the pressing connection seat during use.

[0010] Furthermore, a countersunk portion of a positioning spring is provided at positions corresponding to the first connection hole and the second connection hole on one side opposite to the material pressing piece and the material pressing connection seat, respectively. The countersunk portion ensures that both ends of the spring remain positioned without deviation.

[0011] Furthermore, a sleeve is installed on the upper part of the second connection hole, and a bolt passes through the upper side of the second connection hole and is threadedly connected to the first connection hole, and the bolt and the sleeve are slidably matched. When the pressing piece is subjected to force to compress the spring, the bolt slides upward relative to the sleeve to play a role of sliding adjustment.

[0012] Furthermore, the upper end of the core-pulling channel is configured to be narrowed so that only the rigid core can pass through, so as to form a step that blocks the upper end of the metal tube component. With this structure, it can be ensured that when pressing the material, the lower panel of the pressing member presses against the base, the metal tube component is located in the core-pulling channel, and the rigid core passes through the channel port for the rigid core clamp to be clamped, while the bottom shell assembly of the electronic cigarette can be kept in position.

[0013] Furthermore, the core-pulling channel is connected to the side of the pressing piece. This structure is convenient for processing and manufacturing.

[0014] Furthermore, it also includes a rigid core unloading driving mechanism for driving the rigid core clamp to transfer from the positioning fixture and the rigid core unloading area. The rigid core unloading driving mechanism can drive the core pulling driving mechanism to drive the rigid core clamp to transfer the pulled rigid core to the rigid core unloading area to achieve automatic unloading.

[0015] Furthermore, the rigid core unloading area is provided with a rigid core collecting container and a rigid core material guide arranged above the rigid core collecting container, and the rigid core material guide comprises a material guide channel with an upper opening. The rigid cores are collected by the rigid core collecting container to facilitate material transfer, and the rigid core material guide can ensure that the unloaded rigid cores flow to the core collecting container.

Figure 8 and Fig. 9 As shown, an electrode e1 is arranged at the lower end of the electronic cigarette bottom shell assembly v, and the electrodes e1 are generally installed in pairs. The lower end surface v11 of the electronic cigarette bottom shell assembly v is arranged with an electrode mounting hole v110, and 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 at the lower end surface v11 of the electronic cigarette bottom shell assembly v, and is used for electrically contacting the battery module (not shown). In the example shown in the accompanying drawings, the lower end surface v11 of the electronic cigarette bottom shell assembly v is arranged with one or more magnetic connecting parts e2, which are used to quickly adsorb the magnetic components corresponding to the battery module.

[0029] like Figure 8 and Fig. 9 As shown, the electrode e1 includes an electrode head e11 and an electrode foot e12, and the electrode mounting hole v110 is configured as a step structure. When the electrode e1 is assembled to 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. The purpose of this patent is to automatically assemble the electrode e1 to the electrode mounting hole v110, and automatically assemble the O-ring s to the metal pipe member v2, and to achieve this on a single device.

[0030] The metal tube component v2 contains filter material. During assembly, the filter material needs to be wrapped into the rigid core v3 first, and then assembled into the metal tube component v2 as a whole. The rigid core v3 needs to be extracted in subsequent steps.

[0031] Obviously, the above part only describes the electronic cigarette bottom shell assembly v, but the structure of the electronic cigarette bottom shell assembly v is not the improved content of this patent and belongs to the prior art; this patent involves the automatic extraction of the rigid core v3.

[0032] See also Figures 1 to 5 The core pulling device 6 includes: a plurality of rigid core clamps 6.1 for clamping the rigid core v3 in the metal tube component v2 of the electronic cigarette bottom shell assembly v, and a core pulling driving mechanism 6.2 for driving the rigid core clamps 6.1 to pull the rigid core out of the electronic cigarette bottom shell assembly v.

One embodiment of the rigid core clamp 6.1 is a pneumatic clamp, and in other embodiments, it can also be an electric clamp. Of course, pneumatic clamps and electric clamps are already known. Usually, the clamp head of the clamp can be adjusted according to the specific workpiece, which is well known to those skilled in the art. Figure 4 As shown, the clamping head of the rigid core clamp 6.1 is configured with a V-shaped clamping opening 6.11. The V-shaped clamping opening 6.11 can be adapted to a rigid core v3 with a certain diameter range.

The presser 6.3 restricts the bottom shell assembly v of the electronic cigarette and the metal tube member v2. The configuration of the presser 6.3 can prevent the metal tube member v2 from being deformed or loosened due to force when the rigid core v3 is extracted. One solution of the presser drive mechanism 6.32 is a pneumatic drive, or it can also be an electric drive, both of which are existing.

[0036] See also Figure 5 The material press 6.3 also includes a material press connection seat 6.33. The material press piece 6.31 is connected to the lower side of the material press connection seat 6.33 through a plurality of elastic buffer connection pieces 6.35'.
