[0002] With the updating and iteration of e-cigarette products and the continuous advancement of technology, new types of e-cigarettes have been developed, which have better performance and can better meet user needs.

[0003] However, the atomization core assembly of the electronic cigarette with a new structure, the components and assembly steps of the assembly have all changed. For example, the electronic cigarette bracket tube adjustment and orientation device disclosed in the patent application number CN202321363742.1, and the electronic cigarette inner core automatic production equipment disclosed in the patent application number CN202222136366.4, originally folded the cotton strips and inserted them into the open tube to complete the connection. Before the connection, it was only necessary to simply use a conventional clamping and positioning device on the open tube. However, the clamping and positioning mechanism in the existing automated processing device can no longer adapt to the processing and assembly of the atomization core assembly of the electronic cigarette with a new structure, and cannot support the connection of the cotton strips with the corresponding components in the form of winding. Therefore, a new clamping assembly is urgently needed. Utility Model Content

[0006] Furthermore, it comprises a rotation driving device, and the rotation driving device is used to drive the positioning seat to rotate.

[0007] Furthermore, it comprises a frame, a first bearing seat mounted on the frame, and the positioning seat is rotatably connected to the first bearing seat.

[0008] Furthermore, the elastic member is a spring, which is sleeved on the outer wall of the sliding shaft.

[0010] Furthermore, a stop block is provided between the positioning seat and the abutment plate, and the stop block is used to limit the abutment plate from passing through the through slot and exerting a pressing force on the support frame of the semi-finished component.

[0011] Compared with the prior art, the utility model provides a clamping assembly, which can move the power output end of the holding power device away from the positioning seat, the connecting push plate, and the holding plate after the holding plate presses the semi-finished component. Through this arrangement, when the subsequent rotary drive device drives the positioning seat to rotate, the structure on the holding power device does not appear on the periphery of the positioning seat, the connecting push plate, and the holding plate, and the positioning seat rotates to form cotton strips wrapped around the outer wall of the semi-finished component, causing interference.

DETAILED DESCRIPTION

[0022] Please refer to Figure 1 - Fig. 9 This embodiment provides a clamping assembly for use in an electronic cigarette atomizing core assembly device, and the electronic cigarette atomizing core assembly device includes:

[0023] Clamping assembly 1, abutting assembly 2, forming and enclosing assembly 3, a rotating driving device 4, and a shell cover pressing assembly 5.

[0024] The clamping assembly 1 is used to clamp the semi-finished component and allows the support frame a3 to be exposed, so that the flexible infiltration carrier B can be wrapped around its outer wall during subsequent operation. The semi-finished component is loaded into the clamping assembly 1 for clamping and positioning, which can be done manually or by automatic loading equipment.

[0025] The abutting component 2 is used to press the flexible impregnated carrier strip and the semi-finished component at a position where the flexible impregnated carrier strip is tangent to the semi-finished component after the flexible impregnated carrier strip is abutted against the outer wall of the semi-finished component;

[0026] The flexible impregnated carrier strip is attached to the outer wall of the semi-finished component. The loading of the flexible impregnated carrier strip can be completed by manual or automatic loading equipment. Specifically, the holding component 2 presses the flexible impregnated carrier strip and the semi-finished component, the flexible impregnated carrier strip and the support frame a3 of the semi-finished component are tangent, and the flexible impregnated carrier strip has a small section structure located on the other side of the pressing position, so that the pressing of the two is more stable, preventing the rotary drive device 4 from loosening when driving the winding.

[0027] The molded enclosure component 3 is used to enclose and clamp the flexible infiltrated carrier strip and the semi-finished product component pressed by the abutting component 2; with the enclosed clamping of the molded enclosure component 3, when the rotating drive device 4 drives the clamping component 1 and the abutting component 2 to turn synchronously and the flexible infiltrated carrier strip is wound on the outer wall of the support frame a3, the molded enclosure component 3 plays a role in combing and guiding the flexible infiltrated carrier strip. The molded enclosure component 3 does not clamp the flexible infiltrated carrier strip and the semi-finished product component tightly, but plays a more enclosed limiting role.

[0028] The number of the rotary drive device 4 is one or two, and is used to drive the clamping component 1 and the abutting component 2 to turn synchronously, so as to wrap the flexible impregnated carrier strip around the outer wall of the semi-finished component;

[0029] Because the supporting component 2 presses the position where the flexible impregnated carrier strip is tangent to the semi-finished component, the flexible impregnated carrier strip and the semi-finished component will be separated if the pressure is released. Therefore, in the process of winding the flexible impregnated carrier strip around the outer wall of the semi-finished component, the supporting component 2 must also be rotated together with the clamping component 1. During the rotation, the flexible impregnated carrier strip will gradually be wrapped around the outer wall of the semi-finished component.

[0030] The shell cover pressing assembly 5 is used to press the outer shell frame to wrap the infiltration carrier strip and the semi-finished component after the abutting assembly 2 leaves the assembly area to avoid the position; during the process of the shell cover pressing assembly 5 abutting the outer shell frame, the forming enclosure assembly 3 opens the forming clamps 330 in the forming enclosure assembly 3 from near to far relative to the shell cover pressing assembly 5 step by step from near to far according to the depth of the outer shell frame wrapping the flexible infiltration carrier strip and the semi-finished component, and cancels the clamping to avoid the position.

[0031] Because the flexible impregnated carrier strip is only wound around the outer wall of the semi-finished component and is not completely formed, once the molding clamp 330 in the molding enclosure component 3 completely releases the clamping and enclosure of the flexible impregnated carrier strip, the flexible impregnated carrier strip will be scattered relative to the semi-finished component. Therefore, through the molding enclosure component 3, according to the depth of the outer shell frame sleeved with the flexible impregnated carrier strip and the semi-finished component, the molding clamp 330 in the molding enclosure component 3 is opened step by step from near to far relative to the shell cover press-fitting component 5. The outer shell frame first sleeves the portion of the flexible impregnated carrier strip closest to it, and then the subsequent molding clamp 330 is opened to avoid the position. The outer shell frame is continued to be driven by the shell cover press-fitting component 5 to press and sleeve the unsleeved portion of the flexible impregnated carrier strip, and so on, until it is fully sleeved and the assembly is completed.

[0032] The loading of the outer shell rack can be done manually or by automated equipment.

[0033] Please refer to Fig. 9The assembly device is used to assemble the electronic cigarette atomization core. The semi-finished component A is assembled by other workstations and becomes one of the raw materials. The incoming materials are assembled and processed in the assembly device. The semi-finished component A includes a support tube a1, a heating element a2 sleeved on the outer wall of the support tube a1, and a support frame a3 sleeved on the outer wall of the heating element a2; the raw material of the flexible impregnated carrier strip B is a long cotton strip, which is wound around the outer periphery of the support frame a3, and then the outer shell frame C is sleeved and connected to the flexible impregnated carrier strip B wound around the outer periphery of the support frame a3, thereby completing the assembly of the electronic cigarette atomization core.

[0034] Embodiment 1 (not shown)

[0035] There are two rotating drive devices 4, which may be motors. The two motors respectively drive the clamping assembly 1 and the abutting assembly 2 to perform synchronous rotation.

[0036] Please refer to Figure 7 and Figure 8 The clamping assembly 1 includes a positioning seat 110, a sliding shaft 120, a connecting push plate 130, a holding plate 140, an elastic member 150, and a holding power device 160; the positioning seat 110 is provided with a positioning groove 111 corresponding to the semi-finished component; the connecting push plate 130 and the holding plate 140 are respectively arranged on both sides of the positioning seat 110; the sliding shaft 120 slides through the positioning seat 110, and the two ends of the sliding shaft 120 are respectively connected to the connecting push plate 130 and the holding plate 140. 40 is connected; the elastic member 150 is connected to the connecting push plate 130 and the positioning seat 110, and presses the connecting push plate 130 to move away from the positioning seat 110; the pressing power device 160 is used to drive the pressing plate 140 to move toward the positioning seat 110; the side wall of the positioning seat 110 is provided with a through groove 112 connected to the positioning groove 111; the pressing plate 140 passes through the through groove 112, and at least presses the support frame of the semi-finished component.

[0037] In some embodiments, the supporting power device 160 can be a cylinder, which supports the supporting plate 140 to move it toward the positioning seat 110, and the elastic member 150 is compressed. Since the push plate 130 is connected to the supporting plate 140 through the sliding shaft 120, the supporting plate 140 moves away from the positioning seat 110. Therefore, there is no supporting plate 140 applying a pressing force to the positioning groove 111 through the through groove 112, and the semi-finished component can be loaded or unloaded in the positioning groove 111.

[0038] The abutting power device 160 cancels the abutting of the abutting plate 140 , and the elastic member 150 abuts the connecting push plate 130 to move away from the positioning seat 110 . The abutting plate 140 applies a pressing force to the semi-finished component in the positioning groove 111 through the through groove 112 .

[0039] A stop block 170 is provided between the positioning seat and the abutment plate, and the stop block 170 is used to limit the abutment plate from passing through the through slot and exerting a pressing force on the support frame of the semi-finished component.

[0040] By setting the stop block 170, the depth of the abutment plate extending through the through slot 112 into the positioning slot 111 can be limited, thereby limiting the pressure of the abutment plate passing through the through slot on the support frame of the semi-finished component to prevent damage to the product.

[0041] After the holding plate 140 presses the semi-finished component, the power output end of the holding power device 160 is away from the positioning seat 110 , the connecting push plate 130 , and the holding plate 140 .

[0042] With this arrangement, when the subsequent rotary drive device drives the positioning seat to rotate, the structure on the abutting power device 160 will not appear on the periphery of the positioning seat 110, the connecting push plate 130, and the abutting plate 140, causing interference with the rotation of the positioning seat 110 and the formation of cotton strips wrapped around the outer wall of the semi-finished component.

[0043] The clamping assembly 1 can clamp and position the semi-finished assembly of the electronic cigarette atomizer stably and quickly, and the positions of the components are arranged reasonably, so as to facilitate the processing of the electronic cigarette atomizer core and the unloading after processing.

[0044] Please refer to Figure 3 and Figure 4 The holding component 2 includes a rotator 210 and a holding needle 220 installed at the power output end of the rotator 210 .

[0045] The pressing needle 220 is a slender needle structure, so when pressing the flexible infiltration carrier and the semi-finished component, it does not hinder the subsequent flexible infiltration carrier from being wound around the outer wall of the semi-finished component, and before the subsequent shell cover pressing assembly 5 holds the outer shell frame against the infiltration carrier and the semi-finished component, the pressing needle 220 can be easily withdrawn without causing a major impact.

[0046] The rotator 210 can be any one of a rotary pneumatic finger, a rotary cylinder, a servo, and a motor. The rotator 210 is preferably a rotary pneumatic finger, which has two rotatable clamping fingers of a spiral arm type, and the holding needle 220 is installed on one of the two clamping fingers. The connection installation angle between the rotator 210 and the pressure shaft end of the rotating pressure holder 520 can be adjusted, so the range of motion of the holding needle 220 can be adjusted. The use of rotary pneumatic fingers has low cost on the one hand, and other components of the device also have cylinders as driving sources, so a common pneumatic source can be used; on the other hand, the rotary pneumatic fingers have good self-locking properties, and after the driving stroke is in place, they can avoid easy displacement.

[0047] In the holding component 2, a crank connecting arm 230 is preferably provided, and the holding needle 220 is installed on the clamping finger of the rotary pneumatic finger through the crank connecting arm 230. The crank connecting arm 230 can make the operating position of the rotator 210 and the holding needle 220 be in a position that does not interfere with other components in the device.

[0048] Please refer to Figure 1 and Figure 2 , Figure 6 The forming enclosure assembly 3 includes a transplanting device 310, a clamp 320 provided at the power output end of the transplanting device 310, and a pair of forming clamps 330 provided at the power output end of the clamp 320; when the clamp 320 drives the two jaws of the forming clamp 330 to clamp together, a movable groove 331 is provided between the two jaws to allow the flexible infiltration carrier to move through.

[0049] The movable groove 331 is specifically used to accommodate the portion of the flexible soaked carrier strip that has not been wound onto the support frame a3, so as to prevent the flexible soaked carrier strip from being clamped by a pair of forming clamps 330 and breaking when the subsequent rotating drive device 4 drives the clamping assembly 1 and the supporting assembly 2 to turn synchronously.

[0050] The transplanting device 310 is used to drive the clamp 320 to move closer to or away from the clamp assembly 1. When the clamp 320 is not needed to operate, it is driven away from the clamp assembly 1 to avoid interfering with the operation or loading and unloading of other components.

[0051] The clamp 320 may be a linearly coupled finger cylinder, and a pair of forming clamps 330 are respectively connected to two clamping fingers.

[0052] Please refer to Figure 1 and Figure 2 , Figure 6 The forming enclosure component 3 includes a guide mechanism 340 and a spatial axial adjustment mechanism 350; the guide mechanism 340 is connected to the power output end of the transplanting device 310; the spatial axial adjustment mechanism 350 is installed on the guide mechanism 340; the number of the clamps 320 and the forming clamps 330 is two groups; one of the clamps 320 is connected to the guide mechanism 340; the other clamp 320 is connected to the spatial axial adjustment mechanism 350; the spatial axial adjustment mechanism 350 is used to adjust the distance between the clamp 320 connected to it and the other clamp 320.

[0053] In some embodiments, the guide mechanism 340 includes a guide rail connected to the frame 6 and a slide seat slidably connected to the guide rail, and the clamp 320 corresponding to the lower position of the support frame a3 is installed on the slide seat.

[0054] In this embodiment, the spatial axial adjustment mechanism 350 may be a spatial axial adjustment mechanism 350 in the spatial Z-axis height direction, which may adjust the height of the clamp 320 connected thereto and the distance from another clamp 320. The adjustment direction of the clamp 320 by the spatial axial adjustment mechanism 350 of the present application is not limited to the Z-axis height direction, and may be arranged in an adaptive and selective direction according to the different layout implementations of the components.

[0055] The spatial axial adjustment mechanism 350 includes a mounting frame connected to the slide seat, a guide rail and guide seat group mounted on the mounting frame, and another clamp 320 mounted on the guide seat in the guide rail and guide seat group. The spatial axial adjustment mechanism 350 also has a spring and an adjustment screw. One end of the spring is connected to the clamp 320, and the other end is connected to the mounting frame. The adjustment screw passes through the mounting frame and resists the clamp 320. The spring provides a pulling force to make the clamp 320 move closer to the adjustment screw.

[0058] In this embodiment, the number of the rotary drive device 4 is one set, and the transmission is completed through a series of components. Only one drive motor 410 is needed as a power source, which can save costs and drive the clamping component 1 and the supporting component 2 to perform steering synchronization at the same time, thereby improving processing accuracy.

[0059] It is ensured that during the synchronous turning process of the clamping component 1 and the abutting component 2, the pressing needle 220 always presses and holds the flexible infiltration carrier strip and the semi-finished product component tightly to avoid clamping dislocation.

[0060] When the driving wheel and the driven wheel are sprocket wheels, the transmission member 460 is a chain. When the driving wheel and the driven wheel are synchronous pulleys, the transmission member 460 is a transmission belt.
