Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to a resistance detection device. Background Technology

[0002] Atomizers are mainly used to heat and atomize the aerosol matrix stored inside, generating aerosols for users to inhale. To ensure the amount of aerosol generated during atomization, the output power of the atomizers needs to be tested. The resistance value of the atomizer is an important parameter affecting its output power. Therefore, during the manufacturing process, each atomizer in each batch needs to be tested to determine its resistance value, and the atomizer's qualification is judged based on the resistance value.

[0003] Currently, atomizer resistance detection devices generally suffer from low integration and insufficient space utilization. For example, to avoid structural interference, the resistance detection component and the atomizer positioning component are designed in layers within the device, each occupying space on one side of the device. Support structures need to be set up at corresponding positions, resulting in a large device size. Utility Model Content

[0004] The purpose of this application is to provide a resistance detection device that addresses the problems of low integration and insufficient space utilization in current atomizer resistance detection devices.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide a resistance detection device for detecting the resistance of an atomizer located at a test station. The resistance detection device includes a frame; the frame is provided with a detection component and a positioning component above the test station, and the detection component and the positioning component are spaced apart in the horizontal direction; the detection component includes a detection probe and a first lifting component, the first lifting component being used to drive the detection probe to move along a first adjustment direction to engage with the atomizer; the positioning component includes a positioning member and a second lifting component, the second lifting component being used to drive the positioning member along a second adjustment direction to position and cooperate with the atomizer; wherein, the first adjustment direction and the second adjustment direction are not parallel; as the detection probe and the positioning member move toward the atomizer, the horizontal distance between the detection probe and the positioning member gradually decreases.

[0006] The beneficial effects of the resistance detection device of this application are as follows: both the detection component and the positioning component are set on the frame above the station to be tested, resulting in a high degree of device integration. Furthermore, the first adjustment direction of the detection probe and the second adjustment direction of the positioning component are not parallel, and the horizontal distance between the detection probe and the positioning component changes accordingly with their heights. The horizontal distance between the detection probe and the positioning component is minimal when they are in contact with the atomizer; the horizontal distance increases as the detection probe and the positioning component rise away from the atomizer. Consequently, the movement paths of the detection probe and the positioning component converge towards the atomizer from top to bottom, which helps to increase the installation distance between the first and second lifting components, effectively avoiding rigid interference in the structure; and optimizes the structural layout on the frame, improving space utilization.

[0013] In some embodiments, the atomizer has a detection contact surface facing the detection probe, the detection contact surface having two electrode contacts, and the detection probe including two probes disposed along a first adjustment direction for contacting the electrode contacts.

[0014] In some embodiments, the bottom end of the positioning member is provided with a positioning groove that mates with the atomizer.

[0015] In some embodiments, the angle between the first adjustment direction and the vertical direction is 10° to 60°. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0027] The resistance of an atomizer is a crucial parameter affecting its output power. Therefore, during the manufacturing process, each atomizer in each batch needs to be tested to determine its resistance value. However, current atomizer resistance detection devices generally suffer from low integration and insufficient space utilization. For example, to avoid structural interference, the resistance detection component and the atomizer positioning component are designed as separate layers within the device, each occupying a separate side of space, resulting in a large device size.

[0028] Based on this, in order to solve the above problems, this application designs a resistance detection device. The detection component and the positioning component are both set on the frame and located above the station to be tested, resulting in a high degree of device integration. The first adjustment direction of the detection probe and the second adjustment direction of the positioning component are not parallel, and the horizontal distance between the detection probe and the positioning component changes accordingly with the height of both. The horizontal distance between the detection probe and the positioning component is minimal when they are in contact with the atomizer. The horizontal distance between the detection probe and the positioning component increases when they rise away from the atomizer. Subsequently, the movement paths of the detection probe and the positioning component converge towards the atomizer from top to bottom, which helps to increase the installation distance between the first lifting component and the second lifting component, effectively avoiding structural interference. The structural layout on the frame is optimized, improving space utilization.

[0029] refer to Figure 1 , Figure 2 and Figure 3This application provides a resistance detection device 100 for detecting the resistance of an atomizer 200 located at a test station. The resistance detection device 100 includes a frame 1, and a detection component 2 and a positioning component 3 are provided above the test station on the frame 1. The detection component 2 and the positioning component 3 are spaced apart along the horizontal direction X. The detection component 2 includes a detection probe 210 and a first lifting component 220. The first lifting component 220 is used to drive the detection probe 210 to move along a first adjustment direction Y to dock with the atomizer 200. The positioning component 3 includes a positioning member 310 and a second lifting component 320. The second lifting component 320 is used to drive the positioning member 310 to move along a second adjustment direction Z to limit the engagement with the atomizer 200. The first adjustment direction Y and the second adjustment direction Z are not parallel. As the detection probe 210 and the positioning member 310 move toward the atomizer 200, the distance between the detection probe 210 and the positioning member 310 in the horizontal direction X gradually decreases.

[0030] The specific detection process of the resistance detection device 100 is as follows: the atomizer 200 is transported to the test station. Under the action of the second lifting assembly 320, the positioning component 310 moves along the second adjustment direction Z toward the atomizer 200 to position and cooperate with the atomizer 200 located at the test station, so that the atomizer 200 can be stably maintained at the current test station, effectively limiting the displacement of the atomizer 200. The first lifting assembly 220 drives the detection probe 210 to move along the first adjustment direction Y toward the atomizer 200, so that the detection probe 210 docks with the atomizer 200, and then the detection probe 210 can detect and obtain the resistance value of the atomizer 200. The resistance detection device 100 of this application realizes the automated detection of the resistance of the atomizer 200, which can save labor costs and simplify the detection process, thereby effectively improving the detection efficiency.

[0031] Understandably, the station to be tested is a preset station for the atomizer 200 to perform resistance detection, and the atomizer 200 stays at the station to be tested for detection; a suitable position can be set according to the movement path of the detection probe 210 and the positioning component 310.

[0032] refer to Figure 3 The horizontal direction X is the X direction shown in the figure; for example, the atomizer 200 can be automatically transported along the horizontal direction X.

[0033] Understandably, during the detection process, the detection probe 210 moves along the first adjustment direction Y and the second adjustment direction Z. Both the positioning component 310 and the detection probe 210 need to contact the atomizer 200. However, the atomizer 200 is relatively small. If the first adjustment direction Y and the second adjustment direction Z are set parallel, the first lifting component 220 and the second lifting component 320 will be adjacent to each other, resulting in a narrow installation gap. The lifting and lowering must be strictly synchronized, otherwise mechanical collisions may easily occur, causing structural interference between the detection component 2 and the positioning component 3. Furthermore, an excessively small installation gap will increase the difficulty of installing the device.

[0034] To address the aforementioned issues, the detection device of this application sets the first adjustment direction Y of the detection probe 210 and the second adjustment direction Z of the positioning member 310 to be non-parallel, and the horizontal distance between the detection probe 210 and the positioning member 310 changes accordingly with their heights. The horizontal distance between the detection probe 210 and the positioning member 310 is minimized when they are in contact with the atomizer 200. The horizontal distance between the detection probe 210 and the positioning member 310 increases as they move away from the atomizer 200. Consequently, the movement paths of the detection probe 210 and the positioning member 310 converge from top to bottom toward the atomizer 200, which helps to increase the installation distance between the first lifting assembly 220 and the second lifting assembly 320, effectively avoiding structural interference. This optimizes the structural layout on the frame 1 and improves space utilization.

[0035] Furthermore, both the detection component 2 and the positioning component 3 are mounted on the frame 1 and located above the workstation to be tested, resulting in a high degree of device integration.

[0036] For example, the first adjustment direction Y and the second adjustment direction Z are not set parallel to each other. Specifically, the first adjustment direction Y is set at an angle relative to the vertical direction, and the second adjustment direction Z is set parallel to the vertical direction; or, the first adjustment direction Y is set at an angle relative to the vertical direction, and the second adjustment direction Z is set at an angle relative to the vertical direction; or, the first adjustment direction Y is set parallel to the vertical direction, and the second adjustment direction Z is set at an angle relative to the vertical direction; as long as the two are set non-parallel.

[0037] refer to Figure 1 and Figure 3 In some embodiments, the first adjustment direction Y is tilted relative to the vertical direction. Subsequently, the first lifting assembly 220 is tilted along the first adjustment direction Y relative to the vertical direction, and the detection probe 210 will move in the oblique direction to dock with the atomizer 200.

[0038] refer to Figure 3In some embodiments, while the first adjustment direction Y is tilted relative to the vertical direction, the second adjustment direction Y is parallel to the vertical direction; then the second lifting assembly 320 is arranged in the vertical direction to reduce the width of the device; the positioning member 310 moves vertically downward to position and cooperate with the atomizer 200.

[0039] In other embodiments, while the first adjustment direction Y is tilted relative to the vertical direction, the second adjustment direction Y is also tilted relative to the vertical direction; that is, both the first lifting component 220 and the second lifting component 320 are tilted, forming a V-shape, which provides better spatial avoidance.

[0040] refer to Figures 1 to 3 In some embodiments, the frame 1 includes two supports 110 spaced apart, and a first support structure and a second support structure connected to the two supports 110. The first support structure and the second support structure are arranged spaced apart along the horizontal direction X. A first lifting component 220 is disposed on the first support structure. A second lifting component 320 is disposed on the second support structure.

[0041] Understandably, the test station is located between two supports 110, and the atomizer 200 is transported between the two supports 110. A first support structure is disposed between the two supports 110 and above the test station, for fixing the detection component 2. A second support structure is disposed between the two supports 110 and above the test station, for fixing the positioning component 3. The first and second support structures are spaced apart to avoid structural interference between the detection component 2 and the positioning component 3 mounted on them.

[0042] Furthermore, refer to Figure 1 The detection component 2 and the positioning component 3 are both set on the top of the two side supports 110 and above the station to be tested, resulting in a higher degree of device integration.

[0043] In some embodiments, the first support structure includes a first support plate 111 arranged parallel to the first adjustment direction Y, and the first lifting assembly 220 includes a first fixed part 221 connected to the first support plate 111 and a first movable part 222 movably disposed on the first fixed part 221; the detection probe 210 is disposed on the first movable part 222.

[0044] Specifically, the first lifting assembly 220 can be, but is not limited to, linear drive devices such as cylinders, motors, and hydraulic cylinders; the first support plate 111 is set along the first adjustment direction Y, that is, the first support plate 111 is inclined relative to the vertical direction; the first lifting assembly 220 is connected to the first support plate 111, and then the first lifting assembly 220 will be set inclined relative to the vertical direction along the first adjustment direction Y, and the first movable part 222 moves relative to the first fixed part 221 to drive the detection probe 210 to slide along the first adjustment direction Y.

[0045] In some embodiments, the angle between the first adjustment direction Y and the vertical direction is 10° to 60°. Specifically, the angle between the first adjustment direction Y and the vertical direction can be any value among 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, and 60°.

[0046] In some embodiments, the second support structure includes a vertically arranged second support plate 112, and connecting plates 6 connected to the bracket 110 are respectively provided on both sides of the second support plate 112; the second lifting assembly 320 includes a second fixed part 321 connected to the second support plate 112 and a second movable part 322 movably disposed on the second fixed part 321; the positioning member 310 is disposed on the second movable part 322.

[0047] Specifically, the second lifting component 320 is installed on the second support plate 112. In order to avoid structural interference between the second lifting component 320 and the first lifting component 220, connecting plates 6 are provided on both sides of the second support plate 112. The second support plate 112 is fixed to the bracket 110 through the connecting plates 6. Then, the connecting plates 6 make the second support plate 112 and the first support plate 111 staggered in the horizontal direction X, which is a reasonable structural layout.

[0048] Specifically, the second lifting assembly 320 can be, but is not limited to, a linear drive device such as a cylinder, motor, or hydraulic cylinder; the second support plate 112 is arranged vertically, and the second lifting assembly 320 is connected to the second support plate 112, thereby the second lifting assembly 320 will be arranged vertically, and the second movable part 322 will move relative to the second fixed part 321 to drive the positioning member 310 to slide vertically. In this embodiment, the second adjustment direction Z is the vertical direction.

[0049] refer to Figure 2 In some embodiments, a plurality of first lifting components 220 arranged side by side are provided on the first support structure, and each first lifting component 220 has a detection probe 210 on its first movable part 222; correspondingly, a corresponding number of second lifting components 320 are provided on the second support structure, and a positioning member 310 corresponding to the number of detection probes 210 is provided on the second lifting component 320; thus, the resistance detection device 100 of this application can simultaneously detect multiple atomizers 200, greatly improving the detection efficiency.

[0050] refer to Figure 3 , Figure 4 and Figure 5In some embodiments, the resistance detection device 100 further includes a transmission component 4, which includes a platform 401 for transmission along the horizontal direction X, the platform 401 having a plurality of placement slots 5; the atomizer 200 has electrode contacts 701, the placement slots 5 are used to accommodate the atomizer 200, such that the electrode contacts 701 of the atomizer 200 are located outside the placement slots 5, and are used to dock with the detection probe 210.

[0051] Understandably, the detection probe 210 moves along the first adjustment direction Y. In order for the detection probe 210 to be smoothly connected with the electrode contact 701 of the atomizer 200, the atomizer 200 is tilted and placed in the placement slot 5, and then the detection probe 210 is driven to move along the first adjustment direction Y, so that the detection probe 210 can be connected and contacted with the electrode contact 701.

[0052] The support platform 401 can support multiple atomizers 200, so that multiple atomizers 200 can be transported at the same time. Then, the testing device can perform resistance testing on the atomizers 200 on the support platform 401 in sequence, thereby improving the testing efficiency.

[0053] refer to Figure 1 In some embodiments, the transmission component 4 may also include a transmission belt disposed between two supports 110, with a tray 401 placed on the transmission belt, and the tray 401 is horizontally transmitted through the transmission belt to achieve automated feeding.

[0054] refer to Figure 3 In some embodiments, the atomizer 200 has a detection contact surface 7 facing the detection probe 210, the detection contact surface 7 has two electrode contacts 701, and the detection probe 210 has two probes 8 arranged parallel to the first adjustment direction Y, the probes 8 being used to contact the electrode contacts 701.

[0055] Specifically, the atomizer 200 is placed at an angle in the placement groove 5 and partially protrudes upward from the support 401 so that the detection contact surface 7 faces the detection probe 210.

[0056] Understandably, the detection probe 210 is connected to an external resistance tester or has an internal resistance tester. By using the probe 8 to contact the electrode contact 701, the resistance tester is electrically connected to the atomizer, thereby accurately detecting the resistance of the atomizer 200. Furthermore, the second lifting assembly 320 can control the contact or separation between the probe 8 and the electrode contact 701, making the operation simple and reliable.

[0057] For example, probe 8 can be a spring probe, and the elastic structure can achieve elastic contact, avoiding scratching the detection contact surface 7; and the spring probe can achieve millisecond-level contact / separation, which is suitable for automated testing.

[0058] refer to Figure 1The bottom end of the positioning component 310 is provided with a positioning groove 9 that cooperates with the atomizer 200.

[0059] Specifically, the positioning member 310 moves vertically downward so that the part of the atomizer 200 protruding outside the support 401 can be fitted into the positioning groove 9, and the bottom of the atomizer 200 is embedded in the support 401. Then, the atomizer 200 is clamped between the positioning member 310 and the support 401, effectively limiting the position of the atomizer 200 from shifting, so that the atomizer 200 can be stably maintained at the current position to be tested; ensuring that the probe 8 can move and accurately contact and dock with the electrode contact 701.

[0060] The application does not specify the model of the atomizer 200, that is, the shape of the atomizer 200 can be flask-shaped, rectangular, cylindrical, etc.

[0061] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
