Description

Technical Field

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

[0002] In the production process of electronic cigarettes, the assembly of the bottom shell assembly and the oil tank shell is an important link. The bottom shell assembly of the electronic cigarette is mainly composed of a base part and an atomizer assembly. An O-ring is installed on the metal tube to ensure the sealing of the bottom shell assembly when connected to the oil tank shell. The oil tank shell includes an oil tank with an opening at the lower end and a cigarette holder at the upper end. The cigarette holder is connected to the oil tank and extends to one side of the oil tank to connect a socket for connecting the atomizer assembly. The socket is provided with an assembly hole matching the atomizer assembly. The lower part of the oil tank shell is designed with a joint for connecting with the bottom shell assembly. This joint is also used to connect the battery assembly in some products. In the current assembly technology, the pre-assembly of the bottom shell assembly and the oil tank shell is completed manually, and the press-fitting process of the joint of the oil tank shell and the bottom shell assembly, although with the help of semi-automatic equipment, still requires manual operation.

[0003] In order to realize the automated transformation of the assembly of the bottom shell assembly and the oil tank shell, it is necessary to design an assembly fixture with simple structure, stability and reliability. Summary of the invention

[0006] The oil tank assembly jig of the bottom shell assembly of an electronic cigarette comprises: a jig body, a plurality of first clamping blocks, a plurality of second clamping blocks, a plurality of first elastic members, a plurality of second elastic members and a wedge-shaped mechanism. The jig body is constructed with a plurality of spaced loading seats, each loading seat is constructed with a loading cavity with an upper opening for accommodating at least the lower part of the oil tank shell; the plurality of first clamping blocks can be relatively movably assembled on the first side of each loading seat; the plurality of second clamping blocks can be relatively movably assembled on the second side of each loading seat opposite to the first clamping block, and the first clamping block and the second clamping block are respectively constructed with a workpiece positioning portion at the upper end of the loading seat and adapted to the shape of the oil tank shell joint portion on the opposite side; the plurality of first elastic members act on each first clamping block to reset it relative to the loading seat; the plurality of second elastic members act on each second clamping block to reset it relative to the loading seat. The wedge mechanism includes: a first arc transmission part and a second arc transmission part respectively constructed on the lower sides of the first clamping block and the second clamping block; a first wedge driving part and a second wedge driving part respectively used to drive the first arc transmission part and the second arc transmission part; the first wedge driving part and the second wedge driving part are installed on the lower side of the fixture body through a driving plate, and a reset elastic member for resetting the driving plate downward is arranged between the driving plate and the fixture body, and the driving plate is driven by an external lifting driver to open the workpiece positioning part to receive or release the workpiece.

[0007] The assembly jig of the present application performs initial positioning of the oil tank shell through the loading cavity of the loading seat, and then performs precise positioning through the workpiece positioning parts of the first clamp block and the second clamp block. Since the first clamp block and the second clamp block can be opened relative to the loading cavity and only clamp the joint part of the oil tank shell, damage to the surface of the oil tank shell during taking and placing is avoided. The workpiece positioning part is driven to open by coupling the wedge mechanism with an external lifting driver, so that the workpiece can be received or released in the automated assembly process.

The above structure is adopted to facilitate the assembly of the first guide column and the second guide column with the first clamp block and the second clamp block.

[0011] Furthermore, the loading seat is coupled with a workpiece protection material, and the workpiece protection material is constructed with the loading cavity. By adopting the above scheme, the surface of the oil tank shell can be effectively protected during the loading and unloading of materials and the pre-installation and press-installation process of the bottom shell assembly to ensure that it is not damaged, thereby protecting the qualified rate of the product appearance.

[0012] Furthermore, the first clamping block and the second clamping block are configured with an avoidance groove on the opposite side to avoid a part of the loading seat, and the first clamping block and the second clamping block are respectively configured with a workpiece positioning portion adapted to the shape of the oil tank shell joint portion on the upper side. The avoidance groove is designed on the opposite side of the first clamping block and the second clamping block, and the workpiece positioning portion matching the oil tank shell joint portion is arranged on the upper side, so that the fixture structure is compact and has good stability.
