Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, in particular to a battery processing jig, a power supply host and an atomizer. BACKGROUND

[0002] The atomizer is a device capable of atomizing an aerosol substrate into an aerosol for a user to use, which has been widely used in the medical, beauty and other industries. In the existing atomizer, the atomization principle is usually that the liquid guide cotton sheet is attached to the heating element and surrounds the outer periphery of the heating element, and the heating element is connected to the power supply to generate heat, so as to atomize the aerosol substrate on the liquid guide cotton sheet into an aerosol.

[0003] In the process of processing and producing the atomizer, especially in the fine processing link of the power supply host thereof, one step is crucial, that is, to accurately and correctly install the electrode pin on the battery compartment cover.

Since the electrode pin is small and similar in appearance, workers are prone to mistakenly place the positive and negative electrodes of the electrode pin in reverse during rapid operation. Once the positive and negative electrodes of the electrode pin are incorrectly installed, the battery short circuit problem is likely to occur in the subsequent battery assembly and use process. The battery short circuit not only causes the device to malfunction, but also may cause safety hazards such as battery overheating, even fire, which poses a threat to the quality and safety of the product.

[0033] In the related art, the electrode nail 400 is a kind of precise electrical connection element, and is usually clearly distinguished as positive and negative, which is crucial in the processing process. Due to the small size and similar appearance of the electrode nail 400, workers are prone to mistakenly place the positive and negative electrodes of the electrode nail 400 in reverse during rapid operation. Once the positive and negative electrodes of the electrode nail 400 are incorrectly installed, the battery is likely to cause a short circuit problem during subsequent battery assembly and use.

[0034] The embodiment of the application provides a battery processing jig, and relates to the technical field of electronic atomization, and is mainly used for atomizing an aerosol substrate to form an aerosol for a user.

[0035] In combination with FIGS. 1-4, Figure 1 , Figure 2 , Figure 3 The battery processing jig provided by the embodiment is used for assembling the electrode nail 400 and the battery compartment cover 300, and includes a lower mold 100 and an upper mold 200.

[0036] The lower mold 100 is provided with a placement seat 110 for placing the battery compartment cover 300. The placement seat 110 is provided with an avoidance groove 120 corresponding to two electrode through holes 310 on the battery compartment cover 300. The electrode nail 400 is inserted into the corresponding electrode through hole 310. The two electrode nails 400 respectively have long welding lines 421 and short welding lines 422. The avoidance groove 120 includes a deep part 121 and a shallow part 122. The deep part 121 corresponds to the long welding line 421, and the shallow part 122 corresponds to the short welding line 422. The end surface of the upper mold 200 close to the placement seat 110 is provided with a top column 210 corresponding to the electrode nail 400. The upper mold 200 is configured to drive the top column 210 to approach the placement seat 110 to drive the electrode nail 400 to be tightly matched with the electrode through hole 310.

[0037] In the process of assembling and installing the electrode nail 400 and the battery compartment cover 300, the battery compartment cover 300 is first placed on the placement seat 110. Then, the operator aligns the electrode nail 400 with the avoidance groove 120 and ensures that the long welding line 421 and the short welding line 422 on the electrode nail 400 respectively pass through the electrode through hole 310 on the battery compartment cover 300, and then pass through the deep part 121 and the shallow part 122 of the avoidance groove 120. In this process, the long welding line 421 is guided to the deep part 121 of the avoidance groove 120, and the short welding line 422 enters the shallow part 122. Such a layout not only ensures the orderly arrangement of the welding line 420, but also reserves sufficient space for the subsequent tight matching operation.

[0038] As the upper mold 200 slowly approaches the lower mold 100, the top post 210 approaches the electrode pin 400 and exerts a certain pressure, and the electrode pin 400 is pushed towards the electrode perforation 310 of the battery compartment cover 300 to achieve a tight and tight fit. This step is the key to ensuring good connection between the electrode pin 400 and the battery compartment cover 300. During the entire wire 420 threading process, if the long wire 421 is mistakenly threaded, that is, it enters the shallow part 122, the long wire 421 will not be able to completely thread into the avoidance slot 120 due to its length exceeding the accommodation range of the shallow part 122. The cleverness of this design lies in that it can quickly discover and prompt the operator to adjust through the obvious visual difference or through the recognition of the detection device, thereby effectively avoiding the possible reverse installation problem of the electrode pin 400 and the battery compartment cover 300, reducing the damage of parts caused by assembly errors, and significantly improving the assembly efficiency of the power supply host.

[0039] In some specific embodiments, the top post 210 approaches the top pushing surface of the placement seat 110 with a diameter smaller than the diameter of the pin cover 410 of the electrode pin 400. The importance of this design detail lies in that it can effectively avoid the direct contact of the top pushing surface of the top post 210 with the placement seat 110 of the lower mold 100 during the top pressing process, and cannot exert sufficient pressure on the electrode pin 400. If the diameter of the top pushing surface of the top post 210 is too large, or even equal to or larger than the diameter of the pin cover 410 of the electrode pin 400, the top post 210 is likely to directly press on the placement seat 110 of the lower mold 100 during the top pressing, resulting in that the electrode pin 400 cannot be subjected to sufficient top pressure, and thus cannot achieve a tight fit with the electrode perforation 310.

[0040] By setting the diameter of the top pushing surface of the top post 210 to be smaller than the diameter of the pin cover 410 of the electrode pin 400, it can be ensured that the top post 210 can accurately act on the electrode pin 400 during the top pressing process, and the electrode pin 400 can be stably pushed into the electrode perforation 310 to achieve a sufficient and tight fit.

[0041] In some specific embodiments, the upper mold 200 is provided with an adsorption assembly 220, and the adsorption assembly 220 is used to adsorb the top cover of the electrode pin 400. The main function of the adsorption assembly 220 is to adsorb the top cover part of the electrode pin 400, which can easily and firmly adsorb the electrode pin 400. Through this design, the upper mold 200 can automatically adsorb the electrode pin 400, and accurately and accurately thread the electrode pin 400 on the battery compartment cover 300 after completing the adsorption.

[0042] The automation and precision of this process greatly improve the continuity and stability of the assembly of the electrode peg 400 and the battery compartment cover 300. In the past, manual picking and placing of the electrode peg 400 may be required, which is not only inefficient but also prone to errors. Now, with the adsorption assembly 220, the entire process becomes fast and accurate, greatly shortening the assembly time and reducing the possibility of human error.

[0043] In addition, this automated assembly method also helps to improve production efficiency. As the electrode peg 400 is automatically adsorbed and inserted on the battery compartment cover 300, the subsequent assembly steps can be carried out immediately without waiting for manual intervention, thus realizing continuous and efficient operation of the production line.

[0044] In some specific embodiments, the adsorption assembly 220 includes an adsorption groove 221 and a gas passage 222. The adsorption groove 221 is arranged on the end face of the top column 210 near the placement seat 110, and the gas passage 222 is arranged on the lower mold 100. One end of the gas passage 222 is open and communicates with the adsorption groove 221, and the other end of the gas passage 222 is open and communicates with the negative pressure device. When the negative pressure device starts to work, it will generate strong negative pressure, which is quickly transmitted to the adsorption groove 221 through the gas passage 222. Since the adsorption groove 221 is in close contact with the top cover part of the electrode peg 400, the suction force generated by the negative pressure can firmly adsorb the electrode peg 400 on the top column 210. This process is not only efficient but also safe, greatly improving the accuracy and stability of the assembly of the electrode peg 400 and the battery compartment cover 300.

[0045] In addition, in order to meet different scenarios and needs, the adsorption assembly 220 can also adopt another design: magnetic adsorption. Specifically, an electromagnet can be used as a magnetic adsorption piece to adsorb the electrode peg 400 made of metal material. The advantage of the electromagnet is that it can be quickly turned on and off. When it is needed to adsorb the electrode peg 400, the electromagnet can be powered to generate magnetism; when it is needed to release the electrode peg 400, the electromagnet can be powered off to eliminate the magnetism, realizing fast and convenient operation. This design not only improves the work efficiency, but also increases the flexibility and applicability of the adsorption assembly 220.

[0046] In some specific embodiments, the side wall of the placement seat 110 is provided with a matching groove 111 corresponding to the shape of the battery compartment cover 300, which is used for the embedded matching of the battery compartment cover 300 and the placement seat 110. When the battery compartment cover 300 is placed on the placement seat 110, the edge part of the battery compartment cover 300 will naturally embed into the matching groove 111, like a Figure 1 This embedded matching not only effectively limits and fixes the battery compartment cover 300, avoiding the problem of shaking or displacement in subsequent operations, but also greatly improves the accuracy and stability of the assembly.

[0047] In addition, the placing seat 110 is detachably and fittingly installed with the lower mold 100, which is due to the diversity and variability of the battery compartment cover 300. Since different models of the battery compartment cover 300 can be different in shape and size, different models of the placing seat 110 can be selected according to actual needs to ensure that it can perfectly match various battery compartment covers 300.

[0048] In some specific embodiments, the lower bottom of the lower mold 100 is provided with a fixing seat 130, the lower installation surface of the fixing seat 130 is larger than the cross-sectional area of the lower mold 100, and the fixing seat 130 is used to provide stable support for the lower mold 100; the fixing seat 130 is provided with a connecting hole, and the fixing seat 130 is fixed on the corresponding equipment through the connecting piece and the connecting hole.

[0049] As shown in Figure 4 , Figure 5 and Figure 6 , in the embodiment, a power supply host is also provided, which is processed and assembled by the battery processing jig described above, and the power supply host includes a battery compartment 510, a battery compartment cover 300, and an electrode nail 400.

[0050] The battery compartment 510 is internally provided with a battery; the battery compartment cover 300 is provided on the opening of the battery compartment 510; the battery compartment cover 300 is provided with two electrode perforations 310; the electrode nail 400 has two and is correspondingly provided with the electrode perforation 310, and the electrode nail 400 includes a nail cover 410 and two welding wires 420, the nail cover 410 is connected with the welding wire 420, the welding wire 420 is provided through the corresponding electrode perforation 310 and is respectively connected with the positive and negative electrodes of the battery; the nail covers 410 of the two electrode nails 400 are different in diameter, which facilitates workers to determine the corresponding installation position of the battery compartment cover 300 and the battery compartment 510 according to the different diameters of the nail covers 410 of the two electrode nails 400, and improves the installation efficiency of the workers on the power supply host.

[0051] As shown in Figure 7 , in some specific embodiments, the power supply host further includes a control panel 520, the control panel 520 is arranged on the battery compartment cover 300, and the control panel 520 is provided with a conductive contact 521 corresponding to the nail cover 410, the conductive contact 521 is abutted on the corresponding nail cover 410, and is used for the electrical connection between the control panel 520 and the electrode nail 400, so as to ensure the reliable electrical connection between the control panel 520 and the electrode nail 400.

[0052] In some specific embodiments, the electrode perforation 310 is provided with a stepped counterbore 311 at the end away from the battery, the height of the nail cover 410 of the electrode nail 400 is less than the depth of the stepped counterbore 311, and the end surface of the nail cover 410 away from the battery is lower than the end surface of the battery compartment cover 300 away from the battery; since the nail cover 410 is ingeniously hidden in the stepped counterbore 311, its area exposed to the external environment is greatly reduced, thereby effectively reducing the probability of being affected by external factors (such as dust, moisture, foreign matter, etc.). These external factors are often one of the important reasons for causing battery short circuit and power supply host failure. Therefore, through this design, the risk of battery short circuit can be reduced from the source, and the overall stability and reliability of the power supply host can be improved.

[0053] In addition, the design of the stepped counterbore 311 also takes into account the aesthetics and practicality of the product. It not only makes the assembly of the electrode nail 400 more neat and orderly, but also avoids potential safety hazards caused by the protrusion of the nail cover 410.

[0054] In some specific embodiments, the two electrode nails 400 and / or the two welding lines 420 are different in color; this design is not arbitrary, but based on a deep understanding and application of human visual perception rules. Color, as the most intuitive and sensitive information carrier in the human visual system, can instantly attract people's attention and help people quickly distinguish and identify different objects.

[0055] In the application scenario of the electrode nail 400 and the welding line 420, the design of color differentiation is particularly important. Since the electrode nail 400 and the welding line 420 play a crucial role in the battery assembly process, their correct identification and assembly are directly related to the performance and safety of the battery. Therefore, by giving the electrode nail 400 and the welding line 420 different colors, the difficulty and error rate of workers or detection instruments in the identification process can be effectively reduced, thereby improving the accuracy and safety of production.

[0056] In some embodiments, an atomizer is also provided, which includes the above-mentioned power supply host, and the power supply host is used to supply power to the atomization assembly of the atomizer, thereby facilitating the use safety of the atomizer.
