Description

Technical Field

[0001] This utility model relates to the technical field of atomizer manufacturing, and in particular to an assembly fixture for atomizing cartridge body and bottom cover assembly. Background Technology

[0002] The atomizing cartridge is the core component of an atomizer. It stores the liquid to be atomized and, when powered on, atomizes the liquid. (See also...) Figure 1 Most current atomizing cartridges are designed to include an atomizing cartridge body 10 and a bottom cover assembly 20. The atomizing cartridge body 10 is used to store the liquid to be atomized and to atomize the liquid. The bottom cover assembly 20 is used to seal the internal cavity of the atomizing cartridge body 10. Moreover, the bottom cover assembly 20 integrates at least two electrodes 201 with opposite polarities that are electrically connected to the atomizing cartridge body 10, so as to lead out the positive and negative electrodes of the atomizing cartridge body 10, so that the atomizer host can more easily establish an electrical connection with the atomizing cartridge body 10. Currently, most atomizing bullet bodies 10 and bottom cover assemblies 20 use snap-fit ​​connections for easy assembly or disassembly. That is, one of the atomizing bullet bodies 10 and bottom cover assemblies 20 is provided with a snap-fit ​​202, and the other is provided with a slot 101 that cooperates with the snap-fit ​​202. Existing technology uses manual operation to assemble the atomizing bullet bodies 10 and bottom cover assemblies 20 one by one. This assembly process is relatively laborious, and the efficiency of manual assembly is low, which cannot meet the high-efficiency production requirements of atomizing bullets. Utility Model Content

Both the first cylinders and the second cylinders have an automatic retraction tendency. The handle has a first position and a second position relative to the valve body. When the handle is in the first position, each of the first cylinders and the second cylinders extends outward; when the handle is in the second position, each of the first cylinders and the second cylinders retracts.

[0011] In one technical solution, the extension and retraction direction of the first cylinder is defined as a first direction, and the extension and retraction direction of the second cylinder is defined as a second direction. The position of each of the first cylinders relative to the fixed frame is adjustable in the first direction, and the position of each of the second cylinders relative to the fixed frame is adjustable in the second direction.

The fixing frame is provided with a second waist-shaped hole, which extends in the second direction, and the second cylinder adjusts its position along the second waist-shaped hole in the second direction.

[0013] In one of the technical solutions, the fixing frame includes a base plate, a vertical plate, a first adapter plate, and a second adapter plate;

[0017] In one of the technical solutions, a positioning post for insertion into the bottom cover assembly is provided in the second groove, and a magnet for magnetic attraction with the electrodes of the bottom cover assembly is also provided in the second groove.

[0018] In one of the technical solutions, a push plate is connected between the driver and the second positioning plate, and multiple foot pads are fixed to the bottom of the fixing frame.

[0019] Compared with the prior art, the assembly fixture for the atomizing bullet body and the bottom cover assembly provided by this utility model has at least the following beneficial effects:

[0020] Before operation, the assembly fixture of this solution involves manually placing multiple atomizing bullet bodies into the first groove corresponding to the first positioning plate and multiple bottom cover assemblies into the second groove corresponding to the second positioning plate.

Next, a driver moves the second positioning plate closer to the first positioning plate, assembling the multiple bottom cover assemblies and atomizing bullet bodies one-to-one. This assembly fixture can perform the assembly of multiple bottom cover assemblies and multiple atomizing bullet bodies in one operation, thus improving the assembly efficiency of the bottom cover assemblies and atomizing bullet bodies, thereby increasing the production efficiency of atomizing bullets.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0032] It should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0033] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] Please refer to the following: Figures 2 to 5This utility model provides an assembly fixture for atomizing bullet bodies and bottom cover assemblies. This assembly fixture is used for quickly assembling multiple atomizing bullet bodies 10 and multiple bottom cover assemblies 20. The assembly fixture mainly includes a fixing frame 1, a clamping mechanism 2, a driver 3, a first positioning plate 4, and a second positioning plate 5. The clamping mechanism 2, driver 3, and first positioning plate 4 are all fixed to the fixing frame 1. The top of the first positioning plate 4 is provided with multiple first grooves 41, each of which is used to accommodate one atomizing bullet body 10. The clamping mechanism 2 is arranged above the first positioning plate 4 and is used to apply pressure to the multiple atomizing bullet bodies 10 located on the first positioning plate 4. The pressure is applied downwards to press multiple atomizing bullet bodies 10 together. The second positioning plate 5 is located on one side of the first positioning plate 4. The side of the second positioning plate 5 facing the first positioning plate 4 is provided with multiple second grooves 51, each of which is used to accommodate a bottom cover assembly 20. The driver 3 is connected to the second positioning plate 5 and is used to drive the second positioning plate 5 to move laterally closer to or away from the first positioning plate 4. In fact, the positions of the multiple second grooves 51 and the positions of the multiple first grooves 41 are in a one-to-one correspondence, so that when the second positioning plate 5 moves closer to the first positioning plate 4, the multiple bottom cover assemblies 20 can be assembled with a corresponding atomizing bullet body 10.

[0036] Specifically, before operation, the assembly fixture of this solution involves manually placing multiple atomizing bullet bodies 10 into the first groove 41 corresponding to the first positioning plate 4, and placing multiple bottom cover assemblies 20 into the second groove 51 corresponding to the second positioning plate 5. Then, the clamping mechanism 2 applies a downward force to the multiple atomizing bullet bodies 10 located in the first groove 41 to simultaneously clamp the multiple atomizing bullet bodies 10. Next, the driver 3 drives the second positioning plate 5 to move closer to the first positioning plate 4, so that the multiple bottom cover assemblies 20 and the multiple atomizing bullet bodies 10 are assembled one-to-one. The assembly fixture of this solution can complete the assembly operation of multiple bottom cover assemblies 20 and multiple atomizing bullet bodies 10 in one go. Therefore, this solution is beneficial to improving the assembly efficiency of bottom cover assemblies 20 and atomizing bullet bodies 10, thereby improving the production efficiency of atomizing bullets. At the same time, the assembly fixture of this solution also has the advantages of simple structure and easy operation.

[0037] Please see Figure 2 or Figure 3The pressing mechanism 2 specifically includes at least two pressing components 21. Each pressing component 21 specifically includes a first cylinder 211, a pressure plate 212, and a pressing head 213 connected in sequence. The first cylinder 211 has the advantage of low cost as a power source. The first cylinder 211 is fixed on the fixed frame 1 and is connected to the pressure plate 212 to drive the pressure plate 212 to move up and down. The pressing head 213 is fixed to the bottom of the pressure plate 212 to move up and down with the pressure plate 212. The pressing head 213 is used to apply downward pressure to at least two atomizing bullet bodies 10, that is, the pressing head 213 is used to simultaneously press multiple atomizing bullet bodies 10 to simplify the overall structure. In addition, the pressing head 213 is preferably an elastic member with elasticity. For example, the pressing head 213 can be made of silicone. Because the pressing head 213 is elastic, it can reliably contact multiple atomizing bullet bodies 10 at the same time to reliably press multiple atomizing bullet bodies 10. The pressure plate 212 provides sufficient rigid support for the pressure head 213, which also enables the pressure head 213 to reliably press multiple atomizing bullet bodies 10 simultaneously. Preferably, the pressing mechanism 2 in this embodiment includes two pressing components 21, and preferably each pressure head 213 is used to press two atomizing bullet bodies 10.

[0038] Please refer to them again. Figure 2 or Figure 3 The actuator 3 is preferably a lower-cost second cylinder. A manual control valve 6 is fixed on the mounting bracket 1. The manual control valve 6 is connected to each of the first cylinders 211 and the second cylinder (i.e., the actuator 3) via air pipes. The manual control valve 6 is used to simultaneously control the extension or retraction of each of the first cylinders 211 and the second cylinder (i.e., the actuator 3). By setting this manual control valve 6, the operation can be simplified, thereby further improving the efficiency of operators in assembling multiple atomizing bullet bodies 10 and multiple bottom cover assemblies 20 at one time. Specifically, the manual control valve 6 includes a valve body 61 and a handle 62 movably connected to the valve body 61. The valve body 61 is provided with an air inlet and at least two air outlets. The air inlet is used to connect to an external air source. One air outlet is connected to a second cylinder (i.e., the actuator 3) through an air pipe, and the other air outlet is connected to multiple first cylinders 211 through an air pipe. The first cylinders 211 and the second cylinders (i.e., the actuators 3) are designed to have an automatic retraction tendency. The handle 62 has a first position and a second position relative to the valve body 61. When the handle 62 is in the first position, each of the first cylinders 211 and the second cylinders (i.e., the actuators 3) is pushed outward by the gas. When the handle 62 is in the second position, each of the first cylinders 211 and the second cylinders (i.e., the actuators 3) automatically retracts, thereby facilitating the control of the extension or retraction of the first cylinders 211 and the second cylinders.

[0039] Please see Figure 4Since the manual control valve 6 simultaneously controls the extension of the first cylinder 211 and the second cylinder (i.e., the driver 3), and the first cylinder 211 needs to drive the pressure head 213 to press the atomizing bullet body 10 first, the extension stroke of the first cylinder 211 is preferably shorter than the extension stroke of the second cylinder (i.e., the driver 3). For clarity, let's assume that the extension direction of the first cylinder 211 is the first direction Z, and the extension direction of the second cylinder (i.e., the driver 3) is the second direction X. In order to facilitate adjusting the extension stroke of the first cylinder 211 and the extension stroke of the second cylinder (i.e., the driver 3) to a suitable position, in this embodiment, the first cylinder 211 is designed to be adjustable in position relative to the fixed frame 1 in the first direction Z, and the second cylinder (i.e., the driver 3) is designed to be adjustable in position relative to the fixed frame 1 in the second direction X. More specifically, this solution provides a first oblong hole 121 and a second oblong hole 111 on the mounting bracket 1. The first oblong hole 121 extends in the first direction Z, and the second oblong hole 111 extends in the second direction X. During installation, bolts are used to pass through the first oblong hole 121 to fix each first cylinder 211 to the mounting bracket 1, and bolts are used to pass through the second oblong hole 111 to fix the second cylinder (i.e., the driver 3) to the mounting bracket 1. By providing the first oblong hole 121 and the second oblong hole 111, the first cylinder 211 can be adjusted in the first direction Z, and the second cylinder (i.e., the driver 3) can be adjusted in the second direction X.

[0040] Please refer to the following: Figures 2 to 4The fixing frame 1 is specifically designed to include a base plate 11, a vertical plate 12, a first adapter plate 13, and a second adapter plate 14. The vertical plate 12 is fixed to the base plate 11 and extends longitudinally. The first adapter plate 13 is fixed to the vertical plate 12, and the second adapter plate 14 is fixed to the base plate 11. The number of first adapter plates 13 is the same as the number of clamping assemblies 21. Multiple first adapter plates 13 and multiple first cylinders 211 are fixed in a one-to-one correspondence. The second cylinder (i.e., the driver 3) is fixed to the second adapter plate 14. The aforementioned first oblong hole 121 is provided on the vertical plate 12. The aforementioned second oblong hole 111 is provided on the base plate 11. During installation, the first adapter plate 13 and the first cylinder 211 can be pre-fixed, and then bolts can be passed through the first oblong hole 121 and screwed into the first adapter plate 13. At this time, the first cylinder 211 can be fixed at the specified height. Similarly, the second adapter plate 14 and the second cylinder (i.e., the driver 3) can be pre-fixed, and then bolts can be passed through the second oblong hole 111 and screwed into the second adapter plate 14. At this time, the second cylinder (i.e., the driver 3) can be fixed on the base plate 11. Using this fixing bracket 1, the height of the first cylinder 211 in the first direction Z can be adjusted by adjusting the position of the first adapter plate 13 in the first direction Z, and the position of the second cylinder (i.e., the driver 3) in the second direction X can be adjusted by adjusting the position of the second adapter plate 14 in the second direction X.

[0041] Please see Figures 2 to 4 The assembly fixture in this embodiment also includes a pressure regulating valve 7, which is fixed on the upright plate 12. The pressure regulating valve 7 is set on the path connecting the manual control valve 6 and the first cylinder 211, and / or the pressure regulating valve 7 is set on the path connecting the manual control valve 6 and the second cylinder (i.e., the driver 3). By setting this pressure regulating valve 7, the gas pressure of external gas entering the first cylinder 211 or the second cylinder (i.e., the driver 3) can be controlled, which helps to ensure that the atomizing bullet body 10 can be reliably pressed while the bottom cover assembly 20 can also be reliably assembled with the corresponding atomizing bullet body 10.

[0042] Please refer to the following: Figure 4 and Figure 5 The second groove 51 is provided with a positioning post 52 for insertion into the bottom cover assembly 20, and a magnet 53 for magnetic attraction with the electrodes of the bottom cover assembly 20. By providing the positioning post 52, the bottom cover assembly 20 can be inserted into the second groove 51 in a specific posture, allowing it to properly engage with the atomizing cartridge body 10. By providing the magnet 53, the stability of the bottom cover assembly 20 within the second groove 51 is improved, preventing the bottom cover assembly 20 from detaching from the second groove 51 before being assembled with the atomizing cartridge body 10.

[0043] Please see Figures 2 to 4Preferably, a push plate 8 is connected between the driver 3 and the second positioning plate 5. The push plate 8 provides sufficient rigid support for the second positioning plate 5, ensuring that the multiple bottom cover assemblies 20 on the second positioning plate 5 can be reliably assembled with the corresponding atomizing bullet bodies 10. In addition, multiple foot pads 9 are preferably fixed to the bottom of the fixing frame 1 to support the base plate 11 at a suitable working height, while also allowing more clearance under the base plate 11 so that the operator can more easily move this assembly fixture to a suitable working position.

[0044] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
