[0038] The present application will be further described in details through specific embodiments in combination with the accompanying drawings. In different embodiments, similar elements are denoted by similar element reference numbers. In the following embodiments, many details are described in order to make the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification in order to avoid the core part of the present application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for those skilled in the art according to the description in the specification and general technical knowledge in the art.

[0039] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing one embodiment, and do not mean that the composition and / or order is necessary.

[0040] The serial numbers of components used herein, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meaning. Unless otherwise specified, "connection" and "coupling" as used in the present application include direct and indirect connections (couplings).

[0041] In a common atomization device, the atomization core assembly uses an electric heating heating element to heat the atomization substrate, so that the atomization substrate is atomized and generates aerosol. Among them, the heating element usually has a pin structure extending out of the atomization core, and the pin structure is electrically connected with the power supply assembly through an electrical connection structure (such as an electrode column, an electrode sheet, etc.) to form an electrical connection with the power supply assembly to energize the heating element to heat the heating element. In order to keep the pin structure in abutting state with the electrical connection structure, the pin structure needs to be bent to bend the part of the pin structure extending out of the center hole of the atomization core support to the side to facilitate assembly with the electrical connection structure. The pin described in the present application is the pin structure of the heating element of the atomization core.

[0042] The pin bending jig provided by the present application has a first abutting portion and a second abutting portion on the bending head, and a positioning clamping groove is formed at the end of the first abutting portion away from the second abutting portion. When the pin structure extending out of the target hole is bent, the pin structure is clamped and matched by the positioning clamping groove, the second abutting portion abuts against the side wall of the pin structure and extrudes the pin structure to the inner side wall of the target hole, and the first abutting portion bends the part of the pin structure extending out of the target hole to the side and abuts against the end face of the target hole, so that the extending part is bent. When the pin structure is bent by the above-mentioned pin bending jig, the first abutting portion and the second abutting portion cooperate with each other to accurately position and quickly complete the bending operation, and the pin structure can be kept stable during the operation, thereby improving the precision and accuracy of the pin structure bending operation, making the pin structure have good bending consistency, preventing the pin structure from being assembled and contacted poorly due to poor bending consistency, and also facilitating the improvement of production efficiency.

[0043] Some embodiments of the pin bending jig and the pin bending device provided by the present application are described below in combination with the drawings.

[0044] In the embodiments of the first aspect of the present application, a pin bending jig 100 is provided, as shown in Figure 1 , Figure 2 The pin bending jig 100 includes a main rod body 1 and a bending head 2. The main rod body 1 extends in a first direction, and the bending head 2 is connected to one end of the main rod body 1 in the first direction. The end of the bending head 2 away from the main rod body 1 has a first abutting portion 21 and a second abutting portion 22. The first abutting portion 21 extends in a second direction, and the two ends of the first abutting portion 21 in the second direction have a positioning clamping groove 211 at one end and are connected to the second abutting portion 22 at the other end. When the pin structure 321 is bent,Figure 3 、 Figure 4 and Figure 5 As shown in FIGS. 11, 12 and 13, the positioning slot 211 can be clamped with the pin structure 321 to realize the positioning and alignment between the pin bending jig 100 and the pin structure 321, and the second abutting part 22 can push the pin structure 321 laterally. By rotating the pin bending jig 100, the pin structure 321 can abut against the inner side wall of the target hole 311 (for example, the first central hole 3111 of the atomization core support 31 shown in FIG. 11), while the first abutting part 21 performs a lateral bending operation on the part of the pin structure 321 extending out of the target hole 311, so that the extending part of the pin structure 321 is bent laterally and abuts against the end face of the target hole 311 to form a bent state. Figure 5

[0045] As an example in FIG. 11, in order to realize the lateral pushing and bending operation of the pin structure 321, the second abutting part 22 and the first abutting part 21 form a certain angle, and the specific angle can be set according to the structure of the actual assembly position and the assembly requirements. Figure 2 As an example in FIG. 11, in the atomization core assembly 300, the heating element 32 is usually provided with two pin structures 321 as positive and negative pins, as an example in FIG. 11, the ends of the two pin structures 321 abut against and are bent with different structures, for example, the negative pin is bent to abut against the end face of the first central hole 3111 of the atomization core support 31 (as shown in FIG. 11), and the positive pin is bent to abut against the end face of the second central hole 3112 of the insulating pad 33 (as shown in FIG. 12). After the bending operation, as an example in FIGS. 13 and 14, the base 34 and the electrode nail 35 are assembled to connect the base 34 with the negative pin to form a circuit negative pole, and connect the electrode nail 35 with the positive pin to form a circuit positive pole. The bending operation process of the positive and negative pins is similar, and the pin bending jig 100 in this embodiment can be used for bending operation of both the negative pin and the positive pin.

[0046] Figures 3 to 6 Figure 6 Figure 5 Figure 6 Figure 6 Figure 7 It should be noted that in actual application, when the atomization core assembly 300 is inverted (as an example in FIG. 13), the pin bending jig 100 can be placed above for operation, and when the atomization core assembly 300 is upright, the pin bending jig 100 can be placed below for operation. In addition, the pin bending jig 100 in this embodiment can be manually operated by an operator, or can be automatically operated as part of an automatic device.

[0047] Figure 3 ​​​​​​​​​

[0048] The pin bending jig 100 in the embodiment can realize accurate positioning and quickly complete the bending operation through the cooperation of the first abutting portion 21 and the second abutting portion 22 when the bending operation is performed, can keep the pin structure 321 stable during the operation, thereby improving the precision and accuracy of the pin structure 321 bending operation, making the pin structure 321 have good bending consistency, preventing the pin structure 321 from being assembled and contacted poorly due to poor bending consistency, and being beneficial to improving the production efficiency.

[0049] In further embodiments of the application, as shown in Figure 5 , Figure 8 and Figure 9 , in the pin bending jig 100, the first abutting portion 21 of the bending head 2 is a planar structure and extends along the second direction, and the first angle a is formed between the second direction and the first direction, that is, the angle between the first abutting portion 21 and the extension direction of the bending head 2 is the first angle a. Among them, the first angle a is in the range of 35° to 75°, which can perform corresponding operation actions in the limited space of the target hole 311 on the one hand, and facilitate the transmission of driving force, so that the driving force is fully utilized, improving the operation efficiency. Further, when the first angle a is 45°, the space and stress can be effectively considered, and the operation is more convenient. In addition, when the operator manually operates through the pin bending jig 100, the above-mentioned first angle can make the operation more labor-saving, which is beneficial to reduce the difficulty of bending operation.

[0050] Further, as shown in Figure 10 , in a specific example, the first abutting portion 21 of the bending head 2 further has a first groove 212 extending along the second direction, which is used to accommodate part of the pin structure 321 when the first abutting portion 21 abuts against the pin structure 321, so as to further improve the stability of the pin structure 321 during the bending process. Among them, in the second direction, one end of the first groove 212 is in communication with the positioning clamping groove 211, and the other end extends to the side surface of the second abutting portion 22 facing the positioning clamping groove 211; during the bending operation, the pin structure 321 can be directly guided into the first groove 212 of the first abutting portion 21 by rotating the pin bending jig 100 in the clamping and cooperating state of the pin structure 321 and the positioning clamping groove 211, preventing left and right deviation, and being beneficial to further improving the positioning accuracy of the pin structure 321.

[0051] It should be noted that the first groove 212 can specifically adopt a circular arc groove structure, that is, a groove structure with a circular arc inner wall surface, for example Figure 10The first groove 212 can be in the form of a V-shaped groove, a U-shaped groove, or a rectangular groove, and the specific form can be selected according to the actual situation.

[0052] In the further embodiments of the present application, as shown in the examples of Figure 11 and Figure 12 , in the second direction, the open side of the positioning and clamping groove 211 of the first abutting part 21 is away from the second abutting part 22, so that the pin structure 321 can enter the positioning and clamping groove 211 from the open side and form a clamping fit with the positioning and clamping groove 211; in the first direction, the positioning and clamping groove 211 penetrates through the first abutting part 21 to realize the avoidance of the positioning and clamping groove 211 and prevent interference with the clamping fit between the pin structure 321 and the positioning and clamping groove 211. The specific form of the positioning and clamping groove 211 can be a V-shaped groove as shown in Figures 11 to 13 , so that the two inner wall surfaces arranged in the V shape can simultaneously abut against the two sides of the pin structure 321 to form a clamping and abutting state to realize clamping positioning, or a circular arc groove as shown in Figure 14 , the radius of the circular arc groove is specifically matched with the radius of the pin structure 321, so that the pin structure 321 forms a surface contact with the first groove 212, increases the contact area, and can further improve the stability of the pin structure 321 during the bending operation. Of course, the specific structure of the positioning and clamping groove 211 is not limited to the above structure, and a U-shaped groove, a rectangular groove, or other structure can also be used according to the actual use needs.

[0053] In the further embodiments of the present application, as shown in the examples of Figure 2 , Figure 8 , Figure 9 , in the pin bending jig 100, the second abutting part 22 of the bending head 2 extends along the third direction, the third direction is in the same plane as the first direction and the second direction, and the second abutting part 22 and the first abutting part 21 form a second included angle b. The second included angle b is in the range of 80° to 100°, so that the structure of the first abutting part 21 and the second abutting part 22 is matched with the structure of the target hole 311 during the bending operation, so that the part of the pin structure 321 located in the target hole 311 can abut against the inner side wall of the target hole 311 under the pushing of the second abutting part 22, and the part of the pin structure 321 extending out of the target hole 311 can be bent and abut against the end face of the target hole 311 under the pressure of the first abutting part 21, forming a vertical or nearly vertical bending state. Further, when the second included angle b is 90°, the second abutting part 22 and the first abutting part 21 are in a vertical state to realize the vertical bending operation of the pin structure 321.

[0054] Furthermore, such as Figure 8 and Figure 12 In the example, the surface of the second abutment 22 facing the positioning slot 211 in the second direction is a convex arc-shaped surface 221, that is, the arc-shaped surface 221 protrudes towards the positioning slot 211. This allows the convex arc-shaped surface 221 to adapt to the arc-shaped inner wall of the target hole 311 when the second abutment 22 extends into the target hole 311 and pushes the pin structure 321 laterally. This prevents interference at the edge of the second abutment 22, ensuring that the pin structure 321 can be pushed to abut against the inner wall of the target hole 311. It is understood that the second abutment 22 has a certain width. If the side of the second abutment 22 facing the positioning slot 211 adopts a planar structure, then when the second abutment 22 pushes the pin structure 321 laterally, there will always be a certain gap between the surface of the second abutment 22 and the inner wall of the target hole 311, making it difficult for the pin structure 321 to come close to the inner wall of the target hole 311. The convex arc surface 221 in this embodiment can effectively overcome the above defects and ensure that the pin structure 321 can be close to the inner wall of the target hole 311.

[0055] It should be noted that the radius of the arc surface 221 can be set according to the radius of the target hole 311. For example, the radius of the arc surface 221 can be set to be equal to or slightly smaller than the radius of the target hole 311. The curvature of the arc surface 221 can be set according to the width of the second abutment 22. The smaller the width of the second abutment 22, the smaller the curvature of the arc surface 221. For example, the curvature of the arc surface 221 can be set in the range of 60° to 120° to minimize the space occupied by the second abutment 22 in the target hole 311 while ensuring coverage of the pin structure 321 and ease of operation.

[0056] Furthermore, such as Figure 15 As shown, the second abutment portion 22 of the bending head 2 has a second groove 222 on the surface facing the positioning slot 211 in the second direction. The second groove 222 extends in the third direction, and at both ends of the second groove 222 in the third direction, one end extends to the first abutment portion 21, and the other end passes through the end face of the second abutment portion 22 in the third direction. When the second abutment portion 22 contacts the pin structure 321, the pin structure 321 can be engaged in the second groove 222, so that when the pin structure 321 is pushed close to the inner wall of the target hole 311 by the second abutment portion 22, the pin structure 321 always maintains the state of extending in the third direction, preventing left and right deviation.

[0057] It can be understood that, since the pin structure 321 is a thin cylindrical structure with a certain flexibility, if there is no positioning or fixing structure between the second abutting portion 22 and the pin structure 321, once there is a certain deviation between the pushing direction and the center line of the pin structure 321, the pin structure 321 is prone to be deflected to the left or right side, especially when the contact surface between the second abutting portion 22 and the pin structure 321 is an arc surface 221, the pin structure 321 is more difficult to keep stable. In the embodiment, the second groove 222 is arranged to effectively overcome the above-mentioned defects, so that the pin structure 321 can keep stable during being pushed by the second abutting portion 22, and the phenomenon of left and right deflection is prevented.

[0058] In further embodiments of the present application, as shown in Figure 3 、 Figure 4 and Figure 13 , in the second direction, the width of one end of the positioning clamping groove 211 provided by the first abutting portion 21 is d1, the width of one end of the second abutting portion 22 connected to the first abutting portion 21 is d2, and d1 < d2 is satisfied, so that when the pin structure 321 of the atomizing core is bent towards the center hole end face of the atomizing core support 31, the size of one end of the positioning clamping groove 211 provided by the first abutting portion 21 is matched with the wire passing gap at the edge of the center hole end face, as shown in Figure 4 , so that the first abutting portion 21 can extend into the wire passing gap, and the tail end of the pin structure 321 extends into the wire passing gap after being bent, so as to facilitate the assembly of subsequent other structures.

[0059] In further embodiments of the present application, as shown in Figure 8 and Figure 12 , the first abutting portion 21 and the second abutting portion 22 of the bending head 2 have a circular arc transition surface 23 at the included angle, so that when the pin structure 321 is bent by extending into the target hole 311, the circular arc transition surface 23 can be matched with the round corner at the target hole 311 and the end face. It can be understood that the outer end edge of the target hole 311 is usually provided with a round corner structure, as an example of the center hole of the atomizing core support 31 in Figure 5 , the circular arc transition surface 23 of the bending head 2 can be matched with the round corner of the center hole, so that the pin structure 321 is closer to the surface of the atomizing core support 31; and the pin structure 321 is usually cylindrical, and a part of the bending portion is usually formed as a circular arc structure, rather than a complete right angle structure, and the circular arc transition surface 23 of the bending head 2 can be matched with the circular arc part of the bending portion of the pin structure 321.

[0060] In further embodiments of the present application, as shown in Figure 3 、 Figure 4 and Figure 16As shown, the bending head 2 of the pin bending jig 100 extends along a first direction by a first distance, so that the bending head 2 can extend into the target operating position; in a projection plane perpendicular to the first direction, the projection of the main rod body 1 completely covers the projection of the bending head 2, for example Figure 16 In the example shown in FIG. 1, the maximum width dimension of the bending head 2 in any direction is smaller than the width dimension of the main rod body 1 in the same direction, so as to reduce the thickness of the bending head 2, so as to facilitate the bending operation in the limited space of the target hole 311; at the same time, the thickness of the main rod body 1 is greater than that of the bending head 2, which can ensure that the pin bending jig 100 maintains a certain strength, conducts driving force while avoiding bending itself, and facilitates the operator to hold the main rod body 1, or facilitates connection with the motion mechanism when applied to an automatic device.

[0061] It should be noted that the thickness of the bending head 2 and the main rod body 1 can be set according to the size of the specific operating object (for example, the center hole of the atomizing core support 31). In addition, the shape of the bending head 2 is not limited to the polygonal prism structure shown in Figure 1 , and the main rod body 1 is not limited to the cylindrical structure shown in Figure 1 . Specifically, it can be set according to the operating object and actual use requirements. In addition, the first distance can also be set according to the operating space in actual application.

[0062] In addition, during processing, the bending head 2 and the main rod body 1 can be processed in an integrated structure, for example, the bending head 2 is processed on a whole circular rod structure, of course, the main rod body 1 and the bending head 2 can also be processed separately, and then connected into one by welding or other methods.

[0063] In the embodiments of the second aspect of the present application, a pin bending device 400 is provided, as shown in Figure 1 and Figure 17 , the pin bending device 400 comprises the pin bending jig 100 in any of the embodiments of the first aspect and a motion mechanism 410. The motion mechanism 410 is connected with the main rod body 1 of the pin bending jig 100 and can drive the pin bending jig 100 to move, for example, linearly, rotate, etc., so as to bend the pin structure 321.

[0064] Through the pin bending device 400 in the embodiments, automatic pin bending operation can be realized, which can further improve the operation precision and accuracy, and is beneficial to improve the work efficiency.

[0065] The following describes a specific example of the pin bending device 400 of the present application in conjunction with the drawings.

[0066] The movement mechanism 410 of the pin bending device 400 has corresponding movement components and a control system. The movement components can drive the pin bending jig 100 to move in a three-dimensional space according to control instructions of the control system, including linear movement in X-axis direction, Y-axis direction and Z-axis direction, and rotation in a vertical plane and a horizontal plane, to meet the movement action of the bending operation on the pin structure 321.

[0067] As shown in Figures 1 to 16 , the pin bending jig 100 includes a main rod body 1 and a bending head 2. The main rod body 1 is a circular rod structure and extends in a first direction. One end of the main rod body 1 is connected with the movement mechanism 410. The bending head 2 is located at one end of the main rod body 1 away from the movement mechanism 410 in the first direction, and the bending head 2 is an integral molding structure with the main rod body 1.
