Description

Technical Field

[0001] This application relates to the field of bonding technology for curved outer screens of atomizers, and more particularly to a bonding device for curved outer screens of atomizers. Background Technology

[0002] Electronic atomizers are electronic devices that simulate cigarettes. Their core working principle is to atomize e-liquid at high temperatures using heating elements, thereby producing an inhalable aerosol. In existing products, the curved outer screen (usually a flexible printed circuit board, FPC) is a key appearance and display component, and its assembly quality directly affects the user experience. Currently, the bonding of the curved outer screen is entirely done manually. The specific method is as follows: the operator holds the curved outer screen in one hand and the atomizer housing in the other, first aligning one end of the curved outer screen with one side of the housing for initial bonding, and then gradually wrapping the screen around the curved surface until the entire curved outer screen is completely attached to the housing surface.

[0003] However, this manual process has significant drawbacks: due to the lack of a unified benchmark for the initial pasting position, the bonding path is often inconsistent, and manual wrapping makes it difficult to ensure that the curved outer screen and the curved surface are perfectly aligned, resulting in insufficient tightness. This often leads to appearance and functional problems such as light leakage and incomplete display areas, resulting in a high rework rate and difficulty in guaranteeing quality stability. At the same time, manual operation is extremely inefficient, and the reliance on a large number of manual laborers significantly increases labor costs and manpower input, causing a serious waste of production resources. Summary of the Invention

The technical solution is as follows: This application provides a bonding device for a curved outer screen of an atomizer, comprising: frame; A positioning component has a first positioning groove, a second positioning groove, and a cavity arranged sequentially and interconnected along a vertical direction; the first positioning groove is used to accommodate the atomizer housing and slide in fit with the atomizer housing to guide the atomizer housing to move along the vertical direction; the second positioning groove is used to accommodate a flexible outer screen and constrain the movement of the flexible outer screen perpendicular to the vertical direction; the cavity is used to accommodate the part of the atomizer housing to be bonded and the flexible outer screen to guide the flexible outer screen to bond to the surface of the part of the atomizer housing to be bonded with a preset curvature; A push-up base is provided with a push-up part. The push-up base is movably disposed on the positioning assembly along the vertical direction so that the push-up part extends into or retracts from the cavity. When the push-up part extends into the cavity, the side of the push-up part facing the first positioning groove is aligned with the bottom wall of the second positioning groove to confine the flexible outer screen within the second positioning groove. When the push-up part retracts from the cavity, the push-up part abuts against the flexible outer screen and confines the part to be bonded of the atomizer shell and the flexible outer screen within the cavity. A first elastic element is disposed between the push base and the positioning component. The first elastic element is used to provide a driving force to the push base to restrict the push portion to the position where it extends into the cavity.

[0009] In one embodiment, the positioning component is movably disposed on the frame along a first transverse direction, allowing the positioning component to switch between a first position and a second position. When the positioning component is in the first position, the first positioning groove is aligned with the pressing component; when the positioning component is in the second position, the first positioning groove is misaligned with the pressing component. In one embodiment, the frame has a third positioning groove extending along the first transverse direction, penetrating one side of the frame along the first transverse direction and forming an inlet / outlet. The positioning component is slidably engaged with the third positioning groove and can enter and exit the third positioning groove through the inlet and outlet. When the positioning component is located in the third positioning groove, the positioning component is in the first position. When at least a part of the positioning component exits the third positioning groove, the positioning component is in the second position. The positioning component is provided with stop grooves on both sides along the second lateral direction, the stop grooves extend along the first lateral direction, and the stop grooves penetrate one side of the positioning component along the first lateral direction. The second lateral direction is perpendicular to the vertical direction and the first lateral direction. The frame is provided with two stop components, which are located on both sides of the positioning component along the second transverse direction. Each stop component is slidably engaged with the corresponding stop groove to restrict the positioning component from disengaging from the third positioning groove along the first transverse direction.

[0010] In one embodiment, the frame is screwed with a positioning screw that extends along the first lateral direction, the shank of the positioning screw extending into the third positioning groove and abutting against the positioning component to restrict the first positioning groove to a position aligned with the pressing component.

[0011] In one embodiment, the positioning component includes: A first positioning base has a second positioning groove, the cavity, and a first guide channel. The first guide channel is located on the side of the cavity opposite to the second positioning groove.

Secondly, under the pressure of the atomizer shell, the guidance of the cavity, and the limitation of the pushing component, the flexible outer screen is uniformly bonded to the surface of the shell according to a preset curvature, thereby forming a curved outer screen, ensuring consistent bonding, and making the curved outer screen basically or completely match the curved surface of the atomizer shell, improving the tightness.

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0020] See Figures 1-9 This invention illustrates a preferred embodiment of a bonding device for a curved outer screen of an atomizer, comprising: Rack 1; The positioning component 2 has a first positioning groove 221, a second positioning groove 211, and a cavity 212 arranged sequentially and interconnected in the vertical direction. The first positioning groove 221 is used to accommodate the atomizer housing 100 and slide in cooperation with it, and to constrain the movement of the atomizer housing 100 in the direction perpendicular to the vertical, so as to guide the atomizer housing 100 to move precisely in the vertical direction. The second positioning groove 211 is used to accommodate the flexible outer screen 200 and to constrain the movement of the flexible outer screen 200 in the direction perpendicular to the vertical. The cavity 212 is used to accommodate the part of the atomizer housing 100 to be bonded and the flexible outer screen 200, and to guide the flexible outer screen 200 to be bonded to the surface of the part of the atomizer housing 100 to be bonded with a preset curvature. The push base 3 is provided with a push part 31. The push base 3 is movably disposed on the positioning assembly 2 in the vertical direction so that the push part 31 extends into or exits the cavity 212. When the push part 31 extends into the cavity 212, the side of the push part 31 facing the first positioning groove 221 is aligned with the bottom wall of the second positioning groove 211, that is, the top surface of the push part 31 is aligned with the bottom wall of the second positioning groove 211, so as to restrict the flexible outer screen 200 within the second positioning groove 211. When the push part 31 exits the cavity 212, the push part 31 abuts against the flexible outer screen 200, so as to restrict the part to be bonded of the atomizer shell 100 and the flexible outer screen 200 within the cavity 212. The first elastic element 4 is disposed between the push base 3 and the positioning component 2. The first elastic element 4 is used to provide driving force to the push base 3 so as to restrict the push part 31 to the position of extending into the cavity 212. Drive mechanism 5 is mounted on frame 1, and the output end of drive mechanism 5 can reciprocate in the vertical direction; The pressing component 6 is located at the output end of the driving mechanism 5. The pressing component 6 can move with the output end of the driving mechanism 5. The pressing component 6 is used to push the atomizer shell 100 towards the cavity 212, so that the part of the atomizer shell 100 to be bonded and the flexible outer screen 200 are pushed into the cavity 212. Thus, the flexible outer screen 200 is precisely bonded to the surface of the part of the atomizer shell 100 to be bonded under the pushing action of the atomizer shell 100 and the guiding action of the cavity 212, thereby forming a curved outer screen on the atomizer shell 100.

[0021] The operation process of the bonding device for the curved outer screen of an atomizer according to the present invention is as follows: First, the adhesive side of the flexible outer screen 200 is placed upward in the second positioning groove 211. The second positioning groove 211 accommodates and constrains the movement of the flexible outer screen 200 in the direction perpendicular to the vertical, so as to achieve precise positioning of the flexible outer screen 200. Next, the part to be bonded of the atomizer shell 100 is placed downward in the first positioning groove 221. The first positioning groove 221 accommodates and constrains the movement of the atomizer shell 100 in the direction perpendicular to the vertical, so as to achieve precise positioning of the atomizer outer screen 100. Through the synergistic effect of the first positioning groove 221 and the second positioning groove 211, it is ensured that the parts to be bonded of each atomizer shell 100 can be precisely aligned with the flexible outer screen 200 in a definite and repeatable preset position, providing a stable reference for subsequent bonding. Then, the drive mechanism 5 is activated. The output end of the drive mechanism 5 moves downward, driving the pressing component 6 to move downward synchronously until the pressing component 6 and the atomizer outer screen are aligned. When the shell 100 abuts against and overcomes the driving force of the first elastic member 4, the pushing part 31 of the pushing base 3 exits the cavity 212, while the part to be bonded of the atomizer shell 100 is pushed into the cavity 212. During this process, the flexible outer screen 200 is pushed by the part to be bonded of the atomizer shell 100. With the combined action of the pushing part to be bonded of the atomizer shell 100, the guiding of the cavity 212, and the limiting of the pushing part 31 of the pushing base 3, the flexible outer screen 200 is precisely bonded to the atomizer with a set curvature. The outer shell 100 is shaped to form a curved outer screen on its surface. Then, the output end of the drive mechanism 5 moves upward, causing the pressing component 6 to move upward simultaneously. This releases the pressing component 6 from the atomizer shell 100, relieving the downward pressure applied to it. The first elastic element 4 resets, and the pushing part 31 re-enters the cavity 212, pushing the atomizer shell 100 into the first positioning groove 221. The properly fitted atomizer shell 100 can then be removed. The above steps are then repeated for the next workpiece bonding operation.

[0022] Based on the coordinated operation of the first positioning groove 221, the second positioning groove 211, the cavity 212, the pusher 31, and the first elastic member 4, firstly, it is ensured that the parts of each atomizer shell 100 to be bonded can be precisely aligned with the flexible outer screen 200 at a repeatable preset position, providing a stable reference for subsequent bonding; secondly, under the pressure of the atomizer shell 100, the guidance of the cavity 212, and the limitation of the pusher 31, the flexible outer screen 200 is uniformly bonded to the surface of the shell according to a preset curvature, thereby forming a curved outer screen, ensuring bonding consistency, and making the curved outer screen basically or completely match the curved surface of the atomizer shell 100, improving the sealing degree. Therefore, it can effectively avoid appearance and functional defects such as light leakage and incomplete display areas, reduce rework rate, and thus significantly improve the overall quality of the atomizer.

[0023] Based on the coordinated operation of the frame 1, positioning component 2, pushing base 3, first elastic element 4, driving mechanism 5 and pressing component 6, the bonding equipment can complete the bonding process in an automated or semi-automated manner, reducing manual operation, improving bonding efficiency, saving labor costs, and thus effectively reducing the overall cost of the atomizer.

[0024] Specifically, in one embodiment, the drive mechanism 5 is a cylinder. Of course, as an alternative, the drive mechanism 5 can also be any linear motion mechanism such as a hydraulic cylinder or a linear motor.

[0025] See Figure 1 In one embodiment, the pressing component 6 includes: Movable plate 61, which is located at the output end of drive mechanism 5; Lower pressure plate 62, slidably mounted vertically on movable plate 61, lower pressure plate 62 is used to abut against atomizer housing 100; and The second elastic element 63 is disposed between the moving plate 61 and the lower pressure plate 62. The second elastic element 63 provides a driving force to the lower pressure plate 62, thereby restricting the lower pressure plate 62 to abut against the atomizer housing 100. Thus, after the lower pressure plate 62 abuts against the atomizer housing 100, under the buffering effect of the second elastic element 63, the lower pressure plate 62 can move a preset distance towards the moving plate 61, thereby preventing the atomizer housing 100 and the flexible outer screen 200 from being damaged by hard pressure while applying contact pressure.

[0026] See Figure 1 In one embodiment, the pressing component 6 further includes: The flexible component 7 is located on the side of the lower pressure plate 62 facing the positioning component 2. The flexible component 7 is used to abut against the atomizer housing 100. That is, the lower pressure plate 62 abuts against the atomizer housing 100 through the flexible component 7, realizing soft contact between the lower pressure plate 62 and the atomizer housing 100, thereby further preventing the atomizer housing 100 from being damaged by hard pressure.

[0027] Specifically, the aforementioned flexible component 7 can be made of elastic materials such as rubber or soft silicone to give it good flexibility and thus provide excellent cushioning.

[0028] In one embodiment, the flexible component 7 is detachably mounted on the lower pressure plate 62 so that the flexible component 7 can be replaced, thereby facilitating maintenance.

[0029] In one embodiment, the aforementioned detachable method can be any one of bolt connection, screw connection, magnetic connection, snap-fit ​​connection, etc.

[0030] In one embodiment, the pressing component 6 further includes: The first guide component extends vertically, with its first end connected to the movable plate 61 and its second end slidably engaged with the lower pressure plate 62 to guide the lower pressure plate 62 to move smoothly along the first direction. This ensures that the pressure applied by the lower pressure plate 62 to the atomizer housing 100 is uniform and consistent, thereby improving the fitting accuracy.

[0031] See Figure 1 In one embodiment, the first guide component includes: Adjusting screw 8, the head of adjusting screw 8 is located on the side of moving plate 61 opposite to lower pressure plate 62, the rod of adjusting screw 8 passes through the first through hole of moving plate 61 and the second through hole of lower pressure plate 62 in sequence, and is slidably engaged with the second through hole of lower pressure plate 62; and An adjusting nut (not shown in the figure) is located on the side of the lower pressure plate 62 away from the moving plate 61. The adjusting nut is threadedly connected to the rod of the adjusting screw 8 to prevent the lower pressure plate 62 from disengaging downward from the adjusting screw 8. The second elastic element 63 is sleeved on the outside of the rod of the adjusting screw 8, and its two ends abut against the movable plate 61 and the lower pressure plate 62, respectively. Thus, during installation, firstly, the adjusting screw 8 is passed through the first through hole from the side of the movable plate 61 away from the lower pressure plate 62; then, the second elastic element 63 is sleeved on the rod of the adjusting screw 8; subsequently, the lower pressure plate 62 is placed below the movable plate 61, and the screw rod passes through the second through hole; finally, the adjusting nut is tightened onto the tail end of the adjusting screw 8. This allows the lower pressure plate 62 to be slidably installed on the movable plate 61 in the vertical direction while simultaneously installing the second elastic element 63, resulting in fewer installation steps and higher installation efficiency. In addition, by adjusting the screw 8 and adjusting the nut, the lower pressure plate 62 and the second elastic element 63 can be disassembled, so that the second elastic element 63 can be replaced in time after reaching the end of its service life, which is convenient for inspection and maintenance. Furthermore, since the adjusting nut and adjusting screw 8 are threadedly connected and the rod of adjusting screw 8 can slide with the second through hole of lower pressure plate 62, the position of adjusting nut and lower pressure plate 62 in the vertical direction can be adjusted, thereby changing the buffering force of the second elastic element 63, which is convenient to adapt to the fitting requirements of different types of atomizer curved outer screens.

[0032] See Figure 1In one embodiment, there are multiple first through holes, second through holes, adjusting screws 8, adjusting nuts, and second elastic elements 63. Multiple first through holes are arranged at intervals around the output end of the drive mechanism 5. Each second through hole is located directly below a corresponding first through hole. The rod of each adjusting screw 8 passes through the corresponding first through hole and second through hole in sequence and is screwed to the corresponding adjusting nut. Each second elastic element 63 is sleeved on the outside of the rod of the corresponding adjusting screw 8.

[0033] As an alternative, the first guide component can be a guide post that extends vertically. A guide sleeve is provided on the movable plate 61, and the central hole of the guide sleeve is slidably engaged with the guide post. The two ends of the second elastic member 63 are connected to the movable plate 61 and the lower pressure plate 62, respectively. In this way, the lower pressure plate 62 can also be moved and guided.

[0034] See Figures 1-2 In one embodiment, the positioning component 2 is movably disposed on the frame 1 along a first lateral direction so that the positioning component 2 can switch between a first position and a second position. When the positioning component 2 is in the first position, the first positioning groove 221 is aligned with the pressing component 6 to ensure that the pressing component 6 can accurately act on the atomizer housing 100 located in the first positioning groove 221. When the positioning component 2 is in the second position, the first positioning groove 221 is misaligned with the pressing component 6 to facilitate the placement and removal of the atomizer housing 100 and the flexible outer screen 200. Thus, before bonding, the positioning component 2 is pulled to the second position, causing the first positioning groove 221 to be misaligned with the pressing component 6. Then, the flexible outer screen 200 is placed in the second positioning groove 211, and the atomizer shell 100 is placed in the first positioning groove 221. Then, the positioning component 2 and the atomizer shell 100 and flexible outer screen 200 it carries are pushed back to the first position to ensure that the pressing component 6 can accurately press down on the atomizer shell 100, thereby ensuring the accuracy of the bonding. After bonding, the pressing component 6 is first released from the atomizer shell 100, then the positioning component 2 is pulled out, and finally the atomizer shell 100 with the bonding is taken out, thereby avoiding interference during removal and placement.

[0035] See Figures 1-2 In one embodiment, the frame 1 has a third positioning groove 11, which extends along a first lateral direction and penetrates one side of the frame 1 along the first lateral direction to form an inlet and outlet. The positioning component 2 is slidably engaged with the third positioning groove 11 to guide the positioning component 2 to move precisely along the first lateral direction, and to enter and exit the third positioning groove 11 through the inlet and outlet. When the positioning component 2 is in the third positioning groove 11, the positioning component 2 is in the first position. Thus, through the cooperation between the third positioning groove 11 and the positioning component 2, the positioning component 2 is positioned and limited, thereby ensuring that the first positioning groove 221 is precisely aligned with the pressing component 6. When at least part of the positioning component 2 exits the third positioning groove 11, the positioning component 2 is in the second position, causing the first positioning groove 221 to be misaligned with the pressing component 6. The positioning component 2 is provided with stop grooves 214 on both sides of the second transverse direction. The stop grooves 214 extend along the first transverse direction and penetrate one side of the positioning component 2 along the first transverse direction. The second transverse direction is perpendicular to the vertical direction and the first transverse direction. The frame 1 is provided with two stop components 12, which are located on both sides of the positioning component 2 along the second transverse direction. Each stop component 12 is slidably engaged with the corresponding stop groove 214 to accurately guide the movement of the positioning component 2 along the first transverse direction, ensuring that the positioning component 2 moves smoothly and stably. At the same time, the stroke of the positioning component 2 can be limited to prevent the positioning component 2 from completely disengaging from the third positioning groove 11 when it switches to the second position, that is, to limit the positioning component 2 from disengaging from the third positioning groove 11 along the first transverse direction.

[0036] See Figure 9 In one embodiment, the frame 1 is screwed with a positioning screw 13, which extends along a first lateral direction and is located on the side opposite to the aforementioned inlet and outlet. The shank of the positioning screw 13 extends into the third positioning groove 11 and abuts against the positioning component 2, thereby restricting the first positioning groove 221 to a position aligned with the pressing component 6. Thus, when the positioning component 2 moves to abut against the end of the shank of the positioning screw 13, it is confirmed that the positioning component 2 is in the aforementioned first position. Since the positioning screw 13 is screwed to the frame 1, the position of the positioning screw 13 along the first lateral direction is adjustable, thereby allowing the position of the positioning component 2 in the third positioning groove 11 to be adjusted. This facilitates adaptive adjustment of the relative position between the first positioning groove 221 and the pressing component 6 according to the different screen-mounting requirements of the atomizer housing 100.

[0037] Specifically, the top of the frame 1 is provided with three positioning bars, which form the third positioning groove 11. Among the three positioning bars, the two positioning bars located in the second lateral direction form the inlet and outlet, while the positioning screw 13 is screwed onto the remaining positioning bar that is opposite to the inlet and outlet.

[0038] See Figures 1-8 To facilitate the installation of the jacking base 3 and the first elastic member 4, in one embodiment, the positioning component 2 includes: The first positioning base 21 has the aforementioned second positioning groove 211, the aforementioned cavity 212, the aforementioned stop groove 214, and the first guide channel 213. The first guide channel 213 is located on the side of the cavity 212 away from the second positioning groove 211. The first guide channel 213 communicates with the cavity 212. The first guide channel 213 is slidably engaged with the push part 31 to guide the push part 31 to move smoothly in the vertical direction. A plurality of second positioning bases 22 are disposed on the side of the first positioning base 21 facing the pressing component 6 (i.e., the top of the first positioning base 21), and the plurality of second positioning bases 22 form the aforementioned first positioning groove 221; and The third positioning base 23 is located on the side of the first positioning base 21 away from the second positioning base 22. The third positioning base 23 and the first positioning base 21 form a second guide channel 24. The second guide channel 24 is connected to the first direction channel. The second guide channel 24 and the rest of the pushing base 3 except for the pushing part 31 can be slidably engaged to guide the pushing base 3 to move smoothly and stably in the vertical direction. The first elastic element 4 is disposed between the third positioning base 23 and the push base 3. The positioning assembly 2 is composed of a first positioning base 21, multiple second positioning bases 22 and a third positioning base 23. The first positioning base 21 integrates a second positioning groove 211, a cavity 212, a stop groove 214 and a first guide channel 213. Multiple second positioning bases 22 are arranged around each other to form the first positioning groove 221. The first positioning base 21 and the third positioning base 23 cooperate to define and enclose the second guide channel 24. The three components perform different functions, and the functional areas are clearly defined, which is conducive to separate processing and independent assembly, thereby reducing the difficulty of overall manufacturing and assembly.
