Description

Technical Field

[0001] This application belongs to the technical field of testing device accessories, and in particular relates to an auxiliary testing device. Background Technology

[0002] The aerosol generator contains a heating core, which heats the aerosol matrix through the heating of a stamped mesh. The resistance of the stamped mesh directly affects the power consumption and heating effect of the entire aerosol generator, indirectly impacting atomization efficiency. Excessively high resistance leads to increased power loss and overheating risk, which is detrimental to energy conservation, emission reduction, and product safety. Therefore, after manufacturing the stamped mesh, its resistance must be tested to remove defective meshes with excessively high resistance. Otherwise, the high resistance of the stamped mesh will result in excessive heat generation, gradually reducing the mass of the liquid storage chamber used to store the aerosol matrix. The liquid-guiding cotton will gradually dry out, potentially causing the cotton to become burnt and develop a scorched smell due to insufficient moisture and poor liquid flow, resulting in a poor suction experience for the user.

[0003] Resistance testing of stamped wire mesh is typically performed using resistance testing equipment. This equipment uses a gripper or contact head connected to its testing end. When testing the resistance of the stamped wire mesh, the operator must hold the gripper to hold the mesh or place the contact head directly against it. However, since the testing operation relies on the operator's hands, which are difficult to keep still throughout the testing process, the gripper or contact head is prone to shaking. This results in insufficient contact stability between the testing end of the resistance testing equipment and the stamped wire mesh, leading to large fluctuations and poor stability in the test results. Furthermore, this shaking causes the testing end of the resistance testing equipment to exert an unstable force on the stamped wire mesh, potentially causing deformation and affecting the subsequent use of the stamped wire mesh and the accuracy of the testing. Utility Model Content

[0017] The technical advantages of this application embodiment compared to the prior art are as follows: The auxiliary testing device places the sheet material on the abutment surface of the base, and uses the mounting part rotatably connected to the base to drive the movement of the testing pin.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0029] The aerosol generator contains a heating core, which heats the aerosol matrix through the heating of a stamped mesh. The resistance of the stamped mesh directly affects the power consumption and heating effect of the entire aerosol generator, indirectly impacting atomization efficiency. Excessively high resistance leads to increased power loss and overheating risk, which is detrimental to energy conservation, emission reduction, and product safety. Therefore, after manufacturing the stamped mesh, its resistance must be tested to remove defective meshes with excessively high resistance. Otherwise, the high resistance of the stamped mesh will result in excessive heat generation, gradually reducing the mass of the liquid storage chamber used to store the aerosol matrix. The liquid-guiding cotton will gradually dry out, potentially causing the cotton to become burnt and develop a scorched smell due to insufficient moisture and poor liquid flow, resulting in a poor suction experience for the user.

[0030] Resistance testing of stamped wire mesh is typically performed using resistance testing equipment. This equipment uses a gripper or contact head connected to its testing end. When testing the resistance of the stamped wire mesh, the operator must hold the gripper to hold the mesh or place the contact head directly against it. However, since the testing operation relies on the operator's hands, which are difficult to keep still throughout the testing process, the gripper or contact head is prone to shaking. This results in insufficient contact stability between the testing end of the resistance testing equipment and the stamped wire mesh, leading to large fluctuations and poor stability in the test results. Furthermore, this shaking causes the testing end of the resistance testing equipment to exert an unstable force on the stamped wire mesh, potentially causing deformation and affecting the subsequent use of the stamped wire mesh and the accuracy of the testing.

[0031] To address the aforementioned problems, this application provides an auxiliary testing device for detecting the electrical properties of sheet materials. This auxiliary testing device can maintain stable contact with the sheet material, and the testing equipment can obtain test results through electrical contact with the auxiliary testing device, thereby improving the stability of the test results. The sheet material is a thin sheet-like component made of metal or conductive material that may be involved in electrical performance testing. For example, the sheet material may be a metal foil, battery electrode, conductive grid sheet, metal induction sheet, electromagnetic shielding mesh, heating sheet, etc. Detectable electrical properties may include resistance, resistivity, conductivity, continuity, voltage withstand capability, current carrying capacity, thermoelectric potential, etc.

[0032] In the following embodiments, a stamped mesh sheet with a heating core is used as the example, the electrical property being tested is the resistance value, and the testing equipment is a resistance testing device. The resistance testing device includes a main body, connecting wires, and contacts. Two connecting wires and two contacts are provided. Both connecting wires are electrically connected to the main body and correspond to the positive and negative terminals of the main body, respectively. The two contacts are each connected to the free end of a connecting wire and are used to contact an auxiliary testing device. The contact can be a gripper, which makes electrical contact with the target object by clamping it; or it can be a contact head, which makes electrical contact with the target object by abutting against it. This contact is the contact end of the resistance testing device.

[0033] Please see Figure 1 and Figure 2 In this embodiment, the auxiliary detection device includes a base 10 and an electrical contact component 20.

[0034] The base 10 has an abutment surface 101 for placing the stamped mesh 90. This abutment surface 101 can be flat, curved, or mesh-like; there are no restrictions, as long as it can support the part of the stamped mesh 90 to be tested. This part to be tested is the part that contacts the electrical contact member 20. The base 10 can be placed on a table with the abutment surface 101 facing upwards to support the stamped mesh 90.

[0035] The electrical contact component 20 includes a mounting member 21 and a detection pin 22. The mounting member 21 is rotatably connected to the base 10, and the detection pin 22 is connected to the mounting member 21. When the mounting member 21 rotates relative to the base 10, the detection pin 22 can perform a circular motion. The mounting member 21 can rotate in both the forward and reverse directions. The electrical contact component 20 has a detection position. The mounting member 21 can reach the detection position by rotating in the forward direction, and the mounting member 21 can move the detection pin 22 away from the abutment surface 101 by rotating in the reverse direction. After the stamped mesh 90 is placed on the abutment surface 101, when the electrical contact component 20 is in the detection position, the detection pin 22 can clamp the stamped mesh 90 together with the abutment surface 101. The abutment surface 101 may have a placement area 102, which is located on the rotation path of the detection pin 22. During testing, the mounting component 21 can be rotated in both directions to move the detection pin 22 away from the placement position. Then, the stamped mesh 90 is placed on the placement area 102. The mounting component 21 is then rotated in the forward direction until the detection pin 22 contacts the stamped mesh 90 and, together with the base 10, clamps the stamped mesh 90. At this point, the electrical contact component 20 is in the testing position. In this embodiment, the contact end of the testing device can detect the stamped mesh 90 by contacting the detection pin 22 or other conductive structures electrically connected to the detection pin 22.

[0036] The detection pin 22 can be made of a conductive material with low resistivity, such as silver, copper, aluminum, copper alloy, or aluminum alloy, to reduce the error of the detection result. Two detection pins 22 can be provided, used to connect to the positive and negative terminals of the resistance detection device, respectively. Both the base 10 and the mounting component 21 can be made of rigid insulating materials, such as plastics (e.g., polyethylene, polyvinyl chloride), rubber (e.g., natural rubber, silicone rubber), ceramics (e.g., alumina ceramics, talc ceramics), glass, or mica. Insulating base 10 and mounting component 21 can prevent interference with the detection result.

[0037] The auxiliary testing device places the stamped mesh 90 on the contact surface 101 of the base 10. The mounting component 21, rotatably connected to the base 10, drives the movement of the detection pin 22. In the testing position, the detection pin 22 and the contact surface 101 together clamp the stamped mesh 90, ensuring stable contact and preventing contact wobbling caused by operator's hands. This guarantees the stability and accuracy of the electrical performance testing of the stamped mesh 90. Simultaneously, the base 10 provides effective support for the stamped mesh 90, and the stable clamping of the detection pin 22 and the contact surface 101 prevents deformation of the stamped mesh 90 during testing, better protecting the structural integrity of the sheet material.

[0038] It should be noted that during the rotation of the electrical contact component 20, the operator can apply pressure towards the base 10 to the mounting component 21, so that the detection pin 22 is tightly pressed against the stamped mesh 90, thereby improving detection stability. In other embodiments, the mounting component 21 can also apply pressure to the detection pin 22 by its own weight; this is not limited here. The mounting component 21 can have a damping force during rotation, so that after leaving the detection position, the mounting component 21 can be suspended in the position after the external force is removed, thereby eliminating the inconvenience of the operator needing to support the mounting component 21 at all times.

[0039] Optionally, the contact surface 101 is a plane to provide stable and uniform support for the stamped mesh 90, further reducing the possibility of deformation of the stamped mesh 90 during inspection.

[0040] Optionally, the rotation axis of the mounting component 21 is parallel to the contact surface 101, so that the contact angle and pressure between the detection pin 22 and the stamped mesh 90 are easier to control during the circumferential motion. This allows for stable clamping of the sheet material with the planar contact surface 101, reducing contact instability caused by contact angle deviation. This further improves the stability of the contact between the detection pin 22 and the stamped mesh 90, ensuring the accuracy of the electrical performance measurement of the stamped mesh 90.

[0041] Optionally, the detection pin 22 protrudes from one side of the mounting member 21 in the positive rotation direction to avoid interference between the mounting member 21 and the stamping mesh 90 when the detection pin 22 contacts the stamping mesh 90.

[0042] Optionally, the mounting member 21 is square and has a first mounting surface 2101 and a second mounting surface 2102 facing away from each other. The first mounting surface 2101 is located on one side in the forward rotation direction of the mounting member 21, and the second mounting surface 2102 is located on one side in the reverse rotation direction of the mounting member 21. The detection pin 22 protrudes from the first mounting surface 2101 so as to contact the stamped mesh 90 when the mounting member 21 rotates forward.

[0043] Optionally, the detection pin 22 includes a contact rod and an elastic element. The contact rod is slidably connected to the mounting member 21 and can slide axially between a first position and a second position. When the contact rod is in the first position, its height protruding from the first mounting surface 2101 is greater than its height protruding from the first mounting surface 2101 when the contact rod is in the second position. The elastic element is connected to the mounting member 21 and the contact rod and is used to apply an elastic force to the contact rod to move towards the first position. In this way, when the detection pin 22 contacts the stamped mesh 90, under the action of external force or the gravity of the mounting member 21, the contact rod moves from the first position to the second position, the elastic force of the elastic element increases, and the contact rod elastically abuts against the stamped mesh 90. Thus, the detection pin 22 can buffer the force during the abutment process through its own elastic deformation, avoiding damage to the stamped mesh 90 caused by the instantaneous excessive pressure that may be generated by rigid contact, and further reducing the risk of deformation of the stamped mesh 90. Meanwhile, this elastic property ensures that the detection pin 22 remains in close contact with the sheet surface. Even if the stamped mesh 90 has slight dimensional deviations or surface unevenness, it guarantees stable contact and effectively reduces measurement errors caused by poor contact. This, in turn, more reliably ensures the accuracy and stability of the electrical performance testing of the stamped mesh 90. The detection pin 22 can be a pin.

[0044] Please see Figure 1 and Figure 2In some embodiments, the electrical contact component 20 further includes a connecting pin 23, which is connected to the mounting component 21 and electrically connected to the detection pin 22. The contact end of the resistance detection device can indirectly achieve electrical connection with the stamped mesh 90 through electrical contact with the connecting pin 23. This design avoids positional interference that may be caused by direct contact between the contact end of the detection device and the detection pin 22 or the mesh. At the same time, the connecting pin 23, as an intermediate conduction structure, can stably receive the detection signal, further reducing signal transmission fluctuations caused by changes in contact position. Combined with the stable contact between the detection pin 22 and the mesh, the signal transmission stability of electrical performance detection can be significantly improved, ensuring the accuracy of the measurement results. Two connecting pins 23 may be provided, each electrically connected to one detection pin 22.

[0045] Optionally, the connection pin 23 is located on an extension path of the detection pin 22 to facilitate mounting on the mounting component 21.

[0046] Optionally, the connecting pin 23 protrudes from one side of the mounting member 21 in the opposite rotation direction, i.e., the connecting pin 23 protrudes from the second mounting surface 2102, to increase the contact area with the contact end of the resistance detection device and improve the stability of the contact with the contact end of the resistance detection device. When the contact end of the resistance detection device is a gripper, the gripper can hold the connecting pin 23; when the contact end of the resistance detection device is a contact head, the contact head can abut against the peripheral side of the connecting pin 23. The connecting pin 23 can be a solder ball for ease of processing.

[0047] Please see Figure 1 and Figure 2 In some embodiments, the auxiliary detection device further includes a positioning member 30, which is connected to the base 10 and protrudes from the contact surface 101. The positioning member 30 is used to position the stamped mesh 90 so that the stamped mesh 90 can be confined to the placement position. This positioning member 30 can accurately position the stamped mesh 90 placed on the contact surface 101, stably confining it to the preset placement position, preventing the stamped mesh 90 from shifting relative to the detection pin 22 due to external force or slight movement during the detection process. This not only ensures that the detection pin 22 accurately contacts the target detection point of the stamped mesh 90 each time, reducing measurement errors caused by positional deviations, but also simplifies the operator's mesh placement process, improving detection efficiency. Furthermore, combined with the support of the base 10 and the stable contact structure of the detection pin 22, it further ensures the stability of the detection process and the accuracy of the measurement results.

[0048] Combination Figure 3In one embodiment, the positioning member 30 has a first positioning surface 301 and a second positioning surface 302 that are spaced apart and face each other. The abutment surface 101 has a placement area 102 located between the first positioning surface 301 and the second positioning surface 302. The distance between the first positioning surface 301 and the second positioning surface 302 matches the width of the stamped mesh 90. That is, when the stamped mesh 90 is placed in the placement position, both sides of the stamped mesh 90 in the width direction are respectively in clearance fit with the first positioning surface 301 and the second positioning surface 302 to improve the accuracy of limiting the stamped mesh 90.

[0049] Since the two sides of the stamped mesh 90 are parallel in the width direction, the first positioning surface 301 and the second positioning surface 302 are parallel.

[0050] Optionally, the positioning component 30 includes a first positioning protrusion 31 and a second positioning protrusion 32. Both the first positioning protrusion 31 and the second positioning protrusion 32 protrude from the abutment surface 101 and are spaced apart. The first positioning protrusion 31 faces the first positioning surface 301, and the second positioning protrusion 32 has a second positioning surface 302. The protruding structure of the first positioning protrusion 31 and the second positioning protrusion 32 facilitates processing and installation, can stably maintain the distance between the two positioning surfaces, ensures the consistency of different stamped mesh sheets 90 when placed, and, together with the support of the abutment surface 101 and the stable contact of the detection pin 22, effectively reduces measurement errors caused by positioning deviations. It also allows operators to quickly place the mesh sheet in the correct position, improving detection efficiency.

[0051] Combination Figure 3 In one embodiment, the positioning member 30 further has a third positioning surface 303. The orientation of the third positioning surface 303 is different from that of the first positioning surface 301 and the second positioning surface 302, and it faces the placement area 102. The third positioning surface 303 can limit the stamped mesh 90 placed in the area from another direction. This allows the stamped mesh 90 to be further constrained in other directions by the third positioning surface 303, in addition to the width direction displacement being limited by the first positioning surface 301 and the second positioning surface 302. This achieves precise multi-directional positioning and significantly reduces the possibility of the stamped mesh 90 shifting during the detection process.

[0052] Optionally, the positioning component 30 further includes a support block 33, which protrudes from the abutment surface 101 and has a third positioning surface 303, which is perpendicular to the first positioning surface 301 or the second positioning surface 302. The protruding structure of the support block 33 enhances the stability and structural strength of the third positioning surface 303, enabling it to reliably abut against the side of the stamped mesh 90. Combined with the constraint of the first positioning surface 301 and the second positioning surface 302 in the width direction, it achieves precise positioning of the mesh in two perpendicular directions in the plane, further reducing the risk of displacement of the mesh during the inspection process. The first positioning protrusion 31, the second positioning protrusion 32, and the support block 33 can form a U-shaped structure, and the opening of the U-shaped structure facilitates the pushing of the stamped mesh 90 into the placement position.

[0053] Optionally, the support block 33 includes a first support portion 331, a second support portion 332, and a rotating portion 333. The first support portion 331 and the second support portion 332 are spaced apart, and the rotating portion 333 is connected between the first support portion 331 and the second support portion 332. The mounting member 21 is connected to the rotating portion 333 and is rotatably connected to the first support portion 331 and the second support portion 332 through the rotating portion 333. A third positioning surface 303 is formed on the first support portion 331 and the second support portion 332. The rotatable connection of the mounting member 21 to the rotating portion 333 provides a stable support foundation for the rotation of the mounting member 21. The spaced arrangement of the first support portion 331 and the second support portion 332 can evenly distribute the force, enhance the structural stability of the rotating portion 333, and ensure that the mounting member 21 is not prone to displacement or shaking during rotation, thereby ensuring that the detection pin 22 can stably abut against the stamped mesh 90. The rotating part 333 can be rotatably connected to the first support part 331 and the second support part 332, and fixedly connected to the mounting part 21. Alternatively, it can be fixedly connected to the first support part 331 and the second support part 332, and rotatably connected to the mounting part 21. No limitation is made here. In other embodiments, the mounting part 21 can also be directly rotatably connected to the base 10, or rotatably connected to other structural components connected to the base 10.

[0054] Optionally, the mounting component 21 includes a mounting block 211 and a connecting rod 212. The detection pin 22 and the connecting pin 23 are both connected to the mounting block 211. The first mounting surface 2101 and the second mounting surface 2102 are both disposed on the mounting block 211. The connecting rod 212 protrudes from the mounting block 211, and its extension direction can be perpendicular to the extension direction of the detection pin 22, so that the detection pin 22 is located in the rotation direction of the mounting component 21. The connecting rod 212 can be rotatably connected to the support block 33. This allows the detection pin 22 to be moved away from the rotation axis of the mounting component 21, enabling the detection pin 22 to obtain a larger rotation radius during the rotation of the mounting component 21. This makes it easier to accurately align the detection position of the stamped mesh 90, and moving it away from the rotation axis reduces the impact of positional deviation during rotation, enhancing the stability of contact with the mesh.

[0055] The above are merely preferred embodiments of this application, and only specifically describe the technical principles of this application. These descriptions are only for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application, as well as other specific embodiments of this application that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of this application.
