Description

Technical Field

[0001] This application relates to the technical field of oil injection, and particularly to an oil injection device. Background Art

[0002] The main function of an atomizer is to atomize e-liquid into a mist when powered on. A typical atomizer is provided with absorbent cotton or other oil storage media inside. When manufacturers produce atomizers, they need to inject e-liquid into the absorbent cotton. Currently, it is usually done by setting an injection tube, inserting the injection tube into the absorbent cotton for oil injection, and then removing the injection tube from the absorbent cotton after the oil injection is completed to finish the oil injection work.

[0003] However, during the use of this oil injection method, since the absorbent cotton will absorb e-liquid when injecting oil, the absorbent cotton may be adsorbed on the injection tube. Thus, when the injection tube is removed from the absorbent cotton after the oil injection is completed, the absorbent cotton may be taken out from the semi-finished atomizer, causing the semi-finished atomizer to require subsequent rework, which affects production efficiency and product quality. Summary of the Utility Model

[0029] The present application will be described in detail below with reference to the accompanying drawings and optional embodiments. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features may be combined arbitrarily to form new embodiments.

[0030] As Figure 1 and Figure 2 shown, as a first embodiment of the present application, an oil injection device 100 is disclosed. The oil injection device 100 is used for the oil injection process during the production of the atomizer. The oil injection device 100 is used in cooperation with a transfer device. The transfer device is used to transport the semi-finished atomizer to the lower part of the oil injection device 100 for the oil injection process;

[0031] The oil injection device 100 includes a lifting mechanism, an oil injection assembly 200 and a pressing assembly 300. The oil injection assembly 200 includes an oil injection component 210 and a first mounting structure 220. A plurality of the oil injection components 210 are provided and are respectively installed on the first mounting structure 220 in sequence. The first mounting structure 220 is installed on the lifting mechanism. The lifting mechanism drives the first mounting structure 220 to rise or fall, so as to drive the plurality of oil injection components 210 to move. The pressing assembly 300 includes a first driving member 310, a positioning plate 320 and a fixing plate 330. The first driving member 310 is installed on the fixing plate 330. The output end of the first driving member 310 is fixedly connected to the positioning plate 320, so as to drive the positioning plate 320 to make a reciprocating motion in a direction close to and away from the semi-finished atomizer. A positioning member 323 matching the semi-finished atomizer and an oil injection hole cooperating with the oil injection component 210 are provided on the positioning plate 320. The oil injection component 210 can extend into the oil injection hole. When the conveying device transports the semi-finished atomizer to the oil injection device 100, the first driving member 310 drives the positioning plate 320 to move in a direction close to the fixing plate 330, so that the positioning member 323 cooperates with the semi-finished atomizer, and the positioning plate 320 presses and fixes the semi-finished atomizer. Among them, the lifting mechanism can be a hydraulic lifting mechanism or a cylinder lifting mechanism, etc., which can realize reciprocating lifting motion, and there is no limitation here. Designers can choose and design according to the actual situation. Moreover, the first mounting structure 220 can be fixedly connected and installed with the lifting mechanism, or can be detachably connected and installed through threads or buckles, etc. It should be noted that in this embodiment, the first driving member 310 drives the positioning plate 320 to make a reciprocating motion in a direction close to and away from the semi-finished atomizer, and this direction is the -Y axis and +Y axis directions as shown in Figure 1 ; The first driving member 310 can be a driving member such as a cylinder or a hydraulic rod that can realize reciprocating motion.

[0032] When the oil injection device 100 of this embodiment is working, first, the transfer device transports the semi-finished atomizer to the oil injection device 100, that is, moves the semi-finished atomizer to the lower part of the oil injection device 100. At this time, the pressing assembly 300 works, and the first driving member 310 drives the positioning plate 320 to move in the direction close to the semi-finished atomizer. The positioning member 323 on the positioning plate 320 will cooperate with the semi-finished atomizer so that the positioning plate 320 presses and fixes the semi-finished atomizer. Subsequently, the lifting mechanism works, and the lifting mechanism descends to drive the first mounting structure 220 to descend. Multiple oil injection components 210 move towards the semi-finished atomizer until the oil injection components 210 extend into the oil injection holes on the positioning plate 320 and contact the semi-finished atomizer. Then, the oil injection process starts. When the oil injection process is completed, the lifting mechanism rises to drive the first mounting structure 220 to rise, and multiple oil injection components 210 move away from the semi-finished atomizer, separating the oil injection components 210 from the semi-finished atomizer. During this process, due to the cooperation between the positioning member 323 on the positioning plate 320 and the semi-finished atomizer, the positioning member 323 will extend into the semi-finished atomizer to abut against or be spaced from the oil storage cotton. The semi-finished atomizer is pressed and fixed by the positioning plate 320 for positioning. When the oil injection components 210 are separated from the semi-finished atomizer after oil injection, the oil storage cotton in the semi-finished atomizer will not be taken out, thus avoiding the situation that the semi-finished atomizer needs subsequent rework due to the oil storage cotton in the semi-finished atomizer being taken out, and improving the production efficiency and product quality to a certain extent; Generally speaking, the oil injection device 100 of this embodiment, by arranging the positioning member 323 on the positioning plate 320 that cooperates with the semi-finished atomizer, the positioning member 323 can press and fix the semi-finished atomizer for positioning, so that the oil injection components 210 will not take out the oil storage cotton in the semi-finished atomizer when separated from the semi-finished atomizer after oil injection, improving the production efficiency and product quality to a certain extent; It should be noted that the positioning member 323 is a structure that can extend into the semi-finished atomizer and will not affect the oil injection work of the oil injection components 210. In this embodiment, the positioning member 323 can be composed of two symmetric semi-cones, and the oil injection components 210 pass through between the two semi-cones to contact the semi-finished atomizer.

[0033] When the oil injection device 100 of this embodiment is in use, the positioning member 323 on the positioning plate 320 cooperates with the semi-finished atomizer. The positioning member 323 will extend into the semi-finished atomizer and abut against or be spaced from the oil storage cotton. During this process, the positioning member 323 may come into contact with the e-liquid that has been injected into the semi-finished atomizer, causing the positioning member 323 to be contaminated with e-liquid. If it continues to be used subsequently, it may be contaminated with dust due to the e-liquid, resulting in the positioning member 323 contaminating the oil storage cotton in the semi-finished atomizer. Therefore, in this application, the positioning plate 320 is redesigned. The positioning plate 320 includes a positioning main board 321 and a positioning auxiliary board 322. The positioning main board 321 and the positioning auxiliary board 322 are detachably connected. The positioning member 323 is arranged on the side of the positioning auxiliary board 322 away from the positioning main board 321. The positioning main board 321 is fixedly connected to the output end of the first driving member 310. By designing the positioning plate 320 as the positioning main board 321 and the positioning auxiliary board 322, and arranging the positioning member 323 on the positioning auxiliary board 322, and the positioning auxiliary board 322 and the positioning main board 321 are detachably connected, so that when the positioning member 323 is contaminated with e-liquid and then contaminated with dust, the positioning auxiliary board 322 can be detached from the positioning main board 321, and the contaminated positioning auxiliary board 322 can be replaced to avoid contaminating the oil storage cotton in the semi-finished atomizer during subsequent production. That is, when the positioning auxiliary board 322 is worn out during use, the positioning auxiliary board 322 can be replaced separately. Moreover, the materials of the positioning auxiliary board 322 and the positioning main board 321 can be different. The positioning auxiliary board 322 can be made of plastic, and the positioning main board 321 can be made of metal, which can reduce the manufacturing cost of the oil injection device 100 to a certain extent. Among them, the positioning main board 321 and the positioning auxiliary board 322 can be detachably connected by threaded connection, or can be detachably connected by other connection methods such as snap connection. This is not limited here, and designers can choose and design according to the actual situation.

[0034] Among them, in order to ensure the accuracy of the first driving member 310 when driving the positioning plate 320 to reciprocate in the direction close to the semi-finished atomizer and away from the semi-finished atomizer, a first sliding rail 331 is provided on the fixed plate 330, and a first sliding block 324 is provided on the positioning plate 320 and is matched with the first sliding rail 331. The first sliding block 324 is slidably connected to the first sliding rail 331. When the first driving member 310 drives the positioning plate 320 to reciprocate in the direction close to the semi-finished atomizer and away from the semi-finished atomizer, the first sliding block 324 slides in the first sliding rail 331. The first sliding rail 331 plays a guiding role in the direction of the movement of the positioning plate 320 to ensure that when the first driving member 310 drives the positioning plate 320 to move in the direction close to the semi-finished atomizer, the positioning member 323 on the positioning plate 320 can accurately cooperate with the semi-finished atomizer to press and fix the semi-finished atomizer for limiting; among them, the first sliding block 324 can be fixedly connected to the positioning plate 320 by threaded connection, so that when the first sliding block 324 is worn during long-term use, the first sliding block 324 can be replaced to ensure that the guiding accuracy can still be guaranteed during long-term use.

[0035] As Figures 3 to 7 shown, the number of the oil injection components 210 can be set to half of the number of the semi-finished atomizers in one oil injection process, and the plurality of oil injection components 210 are arranged at intervals to perform a secondary oil injection operation in one oil injection process. In this case, the oil injection assembly 200 further includes a second driving member 201. The first installation structure 220 includes an installation member 230 and a moving plate 240. The moving plate 240 is installed on the lifting mechanism. The second driving member 201 is installed on the moving plate 240. A second sliding rail 241 is provided on the moving plate 240, and a second sliding block 231 is provided on the installation member 230 and is matched with the second sliding rail 241. The second sliding block 231 is slidably connected to the second sliding rail 241. The output end of the second driving member 201 is fixedly connected to the installation member 230 to drive the installation member 230 to reciprocate along the direction of the second sliding rail 241. The second sliding rail 241 can be arranged along the arrangement direction of the semi-finished atomization chamber; among them, the second driving member 201 can be a driving member such as a cylinder or a hydraulic rod that can realize reciprocating motion;

[0036] When the oil injection device 100 is in use, first, the transfer device transports the semi-finished atomizer to the oil injection device 100, that is, moves the semi-finished atomizer to the lower part of the oil injection device 100. At this time, the pressing assembly 300 works, and the first driving member 310 drives the positioning plate 320 to move in the direction close to the semi-finished atomizer. The positioning member 323 on the positioning plate 320 cooperates with the semi-finished atomizer so that the positioning plate 320 presses and fixes the semi-finished atomizer. Subsequently, the lifting mechanism works, and the lifting mechanism descends to drive the moving plate 240 to descend, so that the mounting member 230 descends to drive the plurality of oil injection components 210 to move towards the semi-finished atomizer until the oil injection components 210 extend into the oil injection holes on the positioning plate 320 and contact the semi-finished atomizer. Then, the first oil injection starts. When the oil injection is completed, the lifting mechanism rises to drive the moving plate 240 to rise, and the plurality of oil injection components 210 move away from the semi-finished atomizer, separating the oil injection components 210 from the semi-finished atomizer. Subsequently, the second driving member 201 is started, and the second driving member 201 drives the mounting member 230 to move along the direction of the second slide rail 241 to reach above the semi-finished atomizer that has not been oil-injected. Subsequently, the lifting mechanism works, and the lifting mechanism descends to drive the moving plate 240 to descend, so that the mounting member 230 descends to drive the plurality of oil injection components 210 to move towards the semi-finished atomizer until the oil injection components 210 extend into the oil injection holes on the positioning plate 320 and contact the semi-finished atomizer, and the second oil injection starts. After the oil injection is completed, the lifting mechanism rises to drive the plurality of oil injection components 210 to move away from the semi-finished atomizer, and the second driving member 201 drives the mounting member 230 to move along the direction of the second slide rail 241 to return to the position of the previous oil injection, so as to facilitate the next oil injection process. In this embodiment, by setting the second driving member 201, the second slide rail 241, and the second slider 231, the oil injection process can be divided into two oil injection operations, and the semi-finished atomizer can have a relatively long residence time during the oil injection process, so that the staff can perform a certain visual inspection on the semi-finished atomizer during the production process of this process, so as to facilitate timely discovery of whether there are problems with the semi-finished atomizer during the production work. Moreover, the number of components required for the oil injection device 100 is reduced, that is, the number of oil injection components 210 is reduced, which reduces the production cost to a certain extent.

[0037] As Figure 3As shown, the mounting member 230 includes a first mounting plate 232 and a second mounting plate 233. The first mounting plate 232 is detachably connected to the second mounting plate 233. A plurality of mounting holes 234 are provided on the first mounting plate 232, and a plurality of the oil injection members 210 are respectively installed in the plurality of mounting holes 234. The second slider 231 is disposed on the second mounting plate 233. The first mounting plate 232 and the second mounting plate 233 can be detachably connected by means of a threaded connection; the second mounting plate 233 and the output end of the second driving member 201 are detachably connected. Specifically, a latch 233a is further provided on the second mounting plate 233, and a limiting groove 201a that cooperates with the latch 233a is provided on the output end of the second driving member 201. The latch 233a and the limiting groove 201a cooperate to enable the second driving member 201 to drive the second mounting plate 233 to move, so as to drive the first mounting plate 232 to move, thereby moving the oil injection member 210 installed on the first mounting plate 232 to a preset position for oil injection.

[0038] As Figure 4 and Figure 5 shown, the first mounting structure 220 further includes a limiting support arm 250 and an oil pressure buffer member 260. There are two limiting support arms 250, which are respectively disposed at both ends of the moving plate 240. The oil pressure buffer member 260 is disposed on the limiting support arm 250. When the second driving member 201 drives the mounting member 230 to reciprocate along the direction of the second slide rail 241, both sides of the mounting member 230 are sequentially abutted against the oil pressure buffer members 260 disposed at both ends of the moving plate 240 according to the moving direction; the setting of the oil pressure buffer member 260 can limit the mounting member 230 to prevent the second driving member 201 from exceeding the preset stroke range when driving the mounting member 230, which may cause errors in the oil injection process. Moreover, a limiting bolt can be provided on the limiting support arm 250 to enable the limiting bolt to reposition the mounting member 230. The limiting bolt and the oil pressure buffer member 260 jointly limit the mounting member 230 from exceeding the preset stroke range, thereby ensuring the accurate operation of the oil injection process.

[0039] As Figure 6As shown, the first mounting plate 232 includes a mounting main board 235, a mounting positioning board 236, a pressing block 237, and a locking screw 238. Mounting holes 234 are provided on both the mounting main board 235 and the mounting positioning board 236. The mounting main board 235 and the mounting positioning board 236 are overlapped. The pressing block 237 is arranged on both sides of the mounting main board 235 and the mounting positioning board 236. A threaded hole 235a matching the locking screw 238 is provided on the mounting main board 235. A through hole 237a matching the threaded hole 235a is provided on the pressing block 237. The locking screw 238 extends into the through hole 237a and is threadedly connected to the threaded hole 235a on the mounting main board 235 to fix the pressing block 237 on both sides of the mounting main board 235 and the mounting positioning board 236. And the pressing blocks 237 on both sides will exert a squeezing effect on the mounting main board 235 and the mounting positioning board 236, so that the mounting main board 235 and the mounting positioning board 236 are fixed. Among them, the mounting positioning board 236 is detachably connected to the second mounting plate 233. The mounting positioning board 236 and the second mounting plate 233 can be fixedly installed by screw connection. And, a positioning pin can be arranged between the mounting main board 235 and the mounting positioning board 236 for auxiliary positioning, so as to facilitate alignment when the mounting main board 235 and the mounting positioning board 236 are overlapped.

[0040] As Figure 7 shown, the oil injection component 210 includes an oil injection needle 212 and an oil nozzle 211. The oil nozzle 211 is fixedly connected to the oil injection needle 212. One end of the oil injection needle 212 away from the oil nozzle 211 extends out of the mounting hole 234. One end of the oil nozzle 211 away from the oil injection needle 212 is fixedly connected to a guide oil pipe. When the oil injection device 100 performs the oil injection process, the oil injection needle 212 will extend into the oil injection hole and contact the oil storage cotton in the atomizer semi-finished product. The e-liquid will enter the oil injection needle 212 through the guide oil pipe to be injected into the atomizer semi-finished product and absorbed by the oil storage cotton. And, the design of the oil injection needle 212 can facilitate insertion into the oil storage cotton during oil injection, and the contact area between the oil injection needle 212 and the oil storage cotton is small. When the oil injection needle 212 is withdrawn after oil injection, the probability of taking out the oil storage cotton from the atomizer semi-finished product can also be reduced, which improves the production efficiency and production yield to a certain extent. It should be noted that an abutting portion can be provided on the oil nozzle 211, and a threaded hole can be provided on the mounting main board 235. A butterfly bolt is used to pass through the threaded hole and abut against the abutting portion of the oil nozzle 211 to fix the oil injection component 210 to the mounting main board 235.

[0041] It should be noted that, for the limitations of each step involved in this solution, without affecting the implementation of the specific solution, it is not considered to limit the order of the steps. The steps written in the front can be executed first, or can be executed later, or even can be executed simultaneously. As long as the solution can be implemented, it should be regarded as falling within the protection scope of this application.
