[0037] Embodiment:

[0038] Please refer to Figures 1 to 10 , in the first aspect of this embodiment, a spring pin pressing assembly is provided, including: a pressing head 200 and a placement platform 100 spaced apart from the pressing head 200;

[0039] The placement platform 100 is provided with at least a limiting groove 110 that opens towards the direction of the indenter 200. A support platform 120 protrudes inside the limiting groove 110. A limiting space 100a for the sample to be assembled is formed at an interval between the outer peripheral side of the support platform 120 and the inner wall of the limiting groove 110. The support platform 120 is provided with at least one first limiting structure 121 that matches the indenter 200, and the first limiting structure 121 is used to limit the spring pin.

[0040] Specifically, as Figures 8 to 10 shown, during use, the spring pin 500 to be installed is fixed on the first limiting structure 121 on the support platform 120, and the sample 400 to be assembled is fixed in the limiting space 100a between the outer peripheral side of the support platform 120 and the inner wall of the limiting groove 110. The support platform 120 is inserted into the sample 400 to be assembled, so that the spring pin 500 on the first limiting structure 121 is aligned with the spring pin 500 hole position of the sample 400 to be assembled. The indenter 200 is driven towards the placement platform 100 to apply pressure to the sample 400 to be assembled, so that the spring pin 500 is pressed into the sample 400 to be assembled.

[0041] For such a spring pin pressing assembly, its support platform 120 can be inserted into the cavity of the sample 400 to be assembled. The first limiting structure 121 can not only stably fix the spring pin 500 to improve the stability of the spring pin 500, but also the limiting space 100a formed by the support platform 120 and the limiting groove 110 can well fix the sample 400 to be assembled, greatly improving the alignment accuracy between the spring pin 500 and the sample 400 to be assembled, and further improving the installation quality of the spring pin 500 and the yield rate of the sample to be assembled.

[0042] It should be understood that the shape of the limiting groove 110 matches the sample 400 to be assembled. The placement platform 100 is prepared by copying the shape of the sample 400 to be assembled. In the direction perpendicular to the depth of the limiting groove 110, the limiting groove 110 can be either an asymmetric groove or a symmetric groove. It should be noted that the structure and shape of the sample 400 to be assembled provided in this embodiment and the drawings are only used as an example. The spring pin pressing assembly of the present invention can be copied according to the structure and shape of the sample to be assembled, and is not limited to fixing the sample 400 to be assembled provided in this embodiment.

[0043] When the spring pin pressing assembly is applied to a special-shaped electronic atomization device, the limiting groove 110 is an asymmetric groove, thus forming a foolproof design. The sample 400 to be assembled will not be reversely installed into the limiting space 100a between the limiting groove 110 and the support platform 120, improving the accuracy of the alignment between the spring pin 500 and the sample 400 to be assembled, and improving the working efficiency of the spring pin pressing device 10.

[0044] Further, the first limiting structure 121 has magnetism and is used for magnetically adsorbing the spring needle.

[0045] The first limiting structure 121 with magnetism can better fix the spring needle, prevent the spring needle from shaking and causing deviation, and improve the yield rate of the spring needle pressed onto the sample to be assembled.

[0046] Specifically, as Figure 1 shown, the support platform 120 includes support columns (not labeled in the figure) and a convex platform (not labeled in the figure) protruding from one end of the support columns towards the pressing head 200. The first limiting structure 121 is arranged on the convex platform. The convex platform can have magnetism, or the first limiting structure 121 can have magnetism by installing a magnetic body inside.

[0047] Further, as Figure 1 and 3 shown, the first limiting structure 121 is arranged at one end of the support platform 120 close to the pressing head 200, and the end of the support platform 120 provided with the first limiting structure 121 protrudes from the opening of the limiting groove 110. Such a setting facilitates the placement and removal of the sample to be assembled on the pressing assembly.

[0048] As an example, the support platform 120 can be integrally formed with the placement platform 100, or can be detachably connected to the placement platform 100. When applied to a replaceable cartridge electronic atomization device with different cavity depths, different sizes of the support platform 120 or the placement platform 100 can be replaced, and then it can be applied to different models of replaceable cartridge electronic atomization devices.

[0049] Further, as Figure 2 and 4 shown, the depth of the limiting groove 110 accounts for at least 20% of the length L1 of the support platform 120. The minimum depth L2 of the limiting groove 110 accounts for 20% of the length L1 of the support platform 120, which can ensure that the sample to be assembled is better fixed in the limiting space 100a.

[0050] Further, as Figures 1 to 4 shown, the limiting groove 110 has a fixed area 110a, and the depth L1 of the fixed area 110a of the limiting groove 110 accounts for 60% - 80% of the length L2 of the support platform 120.

[0051] As an example, as Figure 2 and 4 shown, a part of the groove wall of the limiting groove 110 accounts for 60% - 80% of the length of the support platform 120, and these groove walls form the fixed area 110a of the limiting groove 110. The fixed area 110a enables the sample to be assembled to be more stably fixed in the limiting space 100a and makes the positioning of the spring needle by the pressing assembly more reliable.

[0052] In a cross-section perpendicular to the depth direction of the limiting groove 110, along the trajectory of the bottom edge of the limiting groove 110, the trajectory of the groove wall of the fixed area 110a of the limiting groove 110 can account for 30%, 50% or 70% of the trajectory of the entire groove wall of the limiting groove 110, or can be other ratios.

[0053] The fixed area 110a of the limiting groove 110 can be continuous or discontinuous. Those skilled in the art can set the optimal fixed area 110a on the limiting groove 110 according to the shape of the sample to be assembled, such as setting it at opposite ends of the limiting groove 110.

[0054] Between the fixed area 110a of the limiting groove 110 and the non-fixed area, the depth of the limiting groove 110 can gradually decrease to form a transition-shaped or stepped groove wall of the limiting groove 110. Preferably, from the fixed area 110a of the limiting groove 110 to the non-fixed area, the depth of the limiting groove 110 can directly decrease to the minimum depth, which can save the material for preparing the pressing assembly and reduce the preparation cost of the pressing assembly.

[0055] Furthermore, as Figures 1 to 2 shown, at least one positioning hole 1211 is recessed at one end of the support platform 120 close to the pressing head 200. The positioning hole 1211 forms part of the first limiting structure 121, and the positioning hole 1211 is used to fix part of the spring pin.

[0056] As an example, the head end of the spring pin is inserted into the positioning hole 1211, and the tail end faces the pressing head 200. Below the positioning hole 1211, and / or, a magnetic structure can be provided around the positioning hole 1211 to assist in fixing the spring pin by the positioning hole 1211.

[0057] Furthermore, as Figures 1 to 2 shown, at least one support protrusion 1212 matching the pressing head 200 protrudes from the support platform 120 in the direction of the pressing head 200. The support protrusion 1212 is coaxially arranged with the positioning hole 1211, and the positioning hole 1211 and the support protrusion 1212 form the first limiting structure 121.

[0058] As an example, a spring pin assembly groove is coaxially arranged with the spring pin hole position on the sample to be assembled. The support protrusion 1212 is used to insert into the spring pin assembly groove of the sample to be assembled, and the support protrusion 1212 further plays a role in limiting.

[0059] Specifically, both the spring pin assembly groove and the support protrusion 1212 are cylindrical, and the radius of the support protrusion 1212 is smaller than the radius of the spring pin assembly groove.

[0060] Furthermore, as Figures 3 to 4As shown, the support platform 120 is further provided with at least one second limiting structure 122 that matches the pressing head 200, and the second limiting structure 122 is used to limit the magnetic member 600.

[0061] Specifically, a magnetic member 600 can also be installed on the sample to be assembled. The magnetic member 600 plays a role in positioning during the subsequent assembly of the sample to be assembled with the cartridge, and can optimize the assembly process of the sample to be assembled with other components.

[0062] In some embodiments, the placement platform 100 having only the first limiting structure 121 but not the second limiting structure 122 is used to assemble the spring needle to the sample to be assembled, and the placement platform 100 having the first limiting structure 121 and the second limiting structure 122 is used to separately assemble the magnetic member 600 onto the assembled sample, or to simultaneously assemble the magnetic member 600 and the spring needle onto the sample to be assembled.

[0063] Further, as Figure 2 and 4 shown, a positioning hole 1211 is recessed at one end of the support platform 120 close to the pressing head 200, and the positioning hole 1211 forms the first limiting structure 121;

[0064] A positioning groove 1221 is recessed at one end of the support platform 120 close to the pressing head 200. The positioning groove 1221 is coaxially arranged with the positioning hole 1211, and the positioning groove 1221 forms the second limiting structure 122.

[0065] As an example, the magnetic member 600 is installed in the positioning groove 1221. The positioning groove 1221 is coaxially arranged with the positioning hole 1211. The magnetic member 600 is annular and can be sleeved outside the spring needle. The positioning groove 1221 plays a role in positioning the magnetic member 600, and can improve the assembly efficiency and assembly quality of the magnetic member 600 and the sample to be assembled.

[0066] Preferably, the second limiting structure 122 also has magnetism and is used to magnetically adsorb the magnetic member 600. It further plays a role in fixing the magnetic member 600, making the alignment of the magnetic member 600 with the sample to be assembled more accurate.

[0067] Further, as Figure 1 and 3 shown, the edges and corners on the circumferential side of the support platform 120 are provided as arc surfaces, and / or, part of the support platform 120 is cylindrical. Such a setting can reduce the wear between the support platform 120 and the sample to be assembled, and prevent the sample to be assembled from being scratched by the sharp edges and corners of the support platform 120.

[0068] Specifically, in some embodiments, the support platform 120 includes support columns and a convex platform protruding from one end of the support columns toward the indenter 200. The support columns are cylindrical, and the edges of the convex platform are provided with arc-shaped surfaces. In addition, the edges of the support platform 120 can also be rounded.

[0069] Furthermore, as Figure 6 shown, the indenter 200 protrudes with a pressing column 230 that matches the first limiting structure 121. An avoidance space 231 is recessed at one end of the pressing column 230 facing the placement platform 100, and the avoidance space 231 is used for passing through the spring pin.

[0070] Specifically, the indenter 200 includes a fixing portion 210, a connecting portion 220, and a pressing portion that are sequentially connected in the direction toward the placement platform 100.

[0071] The fixing portion 210 is used to be connected to the driving device. The fixing portion 210 has a cylindrical shape with a cross-section parallel to the axis. The distance a from the cross-section to the axis of the fixing portion 210 accounts for 8% - 15% of the radius R1 of the fixing portion 210. When in use, the fixing portion 210 can be inserted and fixed into the indenter assembly groove of the driving device, and locking members such as locking bolts on the driving device apply pressure to the cross-section of the fixing portion 210. The cross-section of the fixing portion 210 can ensure that the indenter 200 is more reliably fixed to the driving device.

[0072] The connecting portion 220 is cylindrical, and the connecting portion 220 is coaxially arranged with the fixing portion 210, and the radius of the connecting portion 220 is greater than the radius of the fixing portion 210. With this setting, when the fixing portion 210 is assembled into the indenter assembly groove of the driving device, the connecting portion 220 can abut against the edge of the indenter assembly groove to limit the fixing portion 210. It should be understood that the connecting portion 220 can have various shapes.

[0073] The pressing portion is a pressing column 230 that matches the first limiting structure 121, and the pressing column 230 protrudes from the connecting portion 220 in the direction toward the placement platform 100. The pressing column 230 is preferably cylindrical. A cylindrical groove is recessed at one end of the pressing column 230 facing the placement platform 100 to form an avoidance space 231. The cylindrical groove is coaxially arranged with the pressing column 230. Since the spring pin is cylindrical, the cylindrical pressing column 230 and the cylindrical groove can evenly apply pressure to the sample to be assembled, improve the yield rate when the spring pin is assembled to the sample to be assembled, and prevent the spring pin from being inserted into the sample to be assembled with different depths and causing skew.

[0074] It should be understood that the specific limitations on the shapes of the fixing portion 210, the connecting portion 220, and the pressing portion above are only for some embodiments. The shapes of the fixing portion 210, the connecting portion 220, and the pressing portion of the indenter 200 include but are not limited to various columnar bodies.

[0075] Preferably, the pressing column 230 and the supporting protrusion 1212 are cylindrical, and a cylindrical groove is coaxially arranged on the pressing column 230 to form an escape space 231. The ratio of the inner diameter R2 of the supporting protrusion 1212 to the inner diameter R3 of the pressing column 230 is 0.75-0.70. The cylindrical groove of the pressing column 230 is arranged to avoid air. Especially in the scenario where the sample to be assembled needs to be assembled with multiple spring pins at the same time, on the one hand, the cylindrical groove avoids air and forms a larger escape space 231 to prevent the pressing column 230 from squeezing the spring pin, damaging or bending the spring pin when the pressing head 200 is slightly offset; on the other hand, even if the pressing head 200 is slightly offset, the pressing column 230 can still apply pressure within the range of the supporting protrusion 1212, ensuring that the user can apply sufficient pressure to the sample to be assembled through the pressing column 230.

[0076] It should be understood that the number of pressing columns 230 matches the supporting protrusion 1212 of the first limiting structure 121, and a plurality of pressing columns 230 may be provided. Those skilled in the art can reasonably set the number of supporting protrusions 1212 and pressing columns 230 according to the number of spring pins that need to be pressed on a single sample to be assembled.

[0077] The shape of the pressing column 230 can be of various types and there is no restriction on the shape. A prism is preferred, and its upper and lower bottom surfaces have the same shape so that pressure can be applied evenly. A cylindrical shape is preferred because while being able to apply pressure evenly, the smooth outer circumference reduces friction damage between parts and is easy to mass produce and process.

[0078] Furthermore, if Figures 1 to 4 As shown, an assembly structure 130 is provided on the side of the placement platform 100 away from the pressure head 200 , and the assembly structure 130 is used for sliding assembly on the support seat 300 of the driving device.

[0079] The assembly structure 130 is slidably connected to the seat 300 of the driving device, which facilitates the installation of the placement platform 100 to the driving device, can quickly adjust the position of the placement platform 100, improve the alignment speed during the spring pin pressing process, and simplify the assembly process.

[0080] Specifically, in some embodiments, a mounting groove with two through ends is concavely provided on the side of the placement platform 100 away from the pressure head 200, and a mounting protrusion matching the mounting groove is convexly provided on the support 300. When in use, the mounting groove of the placement platform 100 is slidably connected to the mounting protrusion of the support 300. When the placement platform 100 is moved to a specific position, the placement platform 100 can be placed and connected to the support 300 through various connections such as threaded connection or snap connection to fix the placement platform 100, and a positioning structure such as a positioning bead can be provided on the support 300.

[0081] See also Figures 1 to 10, in the second aspect of this embodiment, a pressing device 10 is provided, including at least one pressing component and a driving device;

[0082] The pressing head 200 of the pressing component is connected to the driving device, and the driving device is used to drive the pressing head 200 to press the sample to be assembled; an assembling structure 130 is arranged on the side of the placing platform 100 of the pressing component facing away from the pressing head 200, and a bearing seat 300 is arranged on the driving device, and the assembling structure 130 is slidably assembled on the bearing seat 300.

[0083] As an example, as Figure 7 shown, at least one type of placing platform 100 can be placed on the bearing seat 300. For example, the placing platform 100 only having the first limiting structure 121 can be placed alone, or the placing platform 100 having the first limiting structure 121 and the second limiting structure 122 can be placed; according to different production requirements, the same type of placing platform 100 can be continuously and spacedly arranged on the bearing seat 300, or can be cross-spacedly arranged with other types of placing platforms 100 on the bearing seat 300; a plurality of bearing seats 300 can also be arranged on the driving device, and the present invention does not limit the number of the bearing seats 300.

[0084] Such a pressing device 10 can form a batch pressing production line. The pressing device 10 can be sequentially connected with the cartridge pressing process and the cartridge oil injection process, realizing the separation and cyclic operation among the spring pin pressing process, the cartridge pressing process and the oil cup pressing process. Each process does not interfere with each other, which not only improves the assembly efficiency of the spring pins, but also optimizes and improves the overall production efficiency of the replaceable cartridge electronic atomization device.

[0085] In some of the above embodiments, the descriptions of each part of the embodiments have their own emphases. For the parts not detailed in a certain part of the embodiments, reference can be made to the relevant descriptions of other embodiments.

[0086] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
