Description

Technical Field

[0001] This utility model relates to the technical field of automated testing, and in particular to a semi-automatic resistance tester. Background Technology

[0002] Currently, the cartridges for electronic atomizing devices need to undergo resistance testing before assembly to ensure that the cartridges can reliably atomize e-liquid. At present, resistance testing is mostly performed on each cartridge manually, which has the disadvantage of low testing efficiency and cannot meet the needs of high-efficiency production of electronic atomizing devices. Therefore, it is necessary to design a machine that can automatically perform resistance testing. Utility Model Content

[0003] This invention provides a semi-automatic resistance testing machine, which mainly solves the technical problem of how to efficiently complete the resistance testing of e-cigarette cartridges.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A semi-automatic resistance tester includes a drive mechanism, a multi-channel test head, several transfer mechanisms, and several material trays;

[0006] The tray has multiple rows of test areas, each row of test areas including multiple test holes for placing objects to be tested. The trays are connected one-to-one with the transfer mechanism. The transfer mechanism is used to drive a corresponding tray to move along the Y direction. The multi-channel test head is located above the trays. The drive mechanism is connected to the multi-channel test head and is used to drive the multi-channel test head to move along the X and Z directions. The range of the multi-channel test head moving in the X direction includes being above several trays. The multi-channel test head moves downward in the Z direction to test the resistance of multiple objects to be tested in one row of test areas.

[0007] In one technical solution, multiple rows of test areas are arranged sequentially along the Y direction, each row of test areas includes multiple test holes arranged sequentially along the X direction, and the multi-channel test head includes multiple test heads arranged sequentially along the X direction. The spacing between two adjacent test heads is the same as the spacing between two adjacent test holes in each row of test areas. When the tray moves along the Y direction under the drive of the transfer mechanism, any row of test areas can move directly below the multi-channel test head.

[0008] In one of the technical solutions, the multi-channel test head also includes a fixed base, a mounting base, and an elastic element;

[0009] The fixed base is connected to the driving mechanism, the mounting base is disposed below the fixed base and is slidably connected to the fixed base along the Z direction, the elastic element is disposed between the fixed base and the mounting base, and the mounting base has a downward movement tendency away from the fixed base due to the elastic force of the elastic element, and the plurality of test heads are fixedly fixed on the mounting base at intervals along the X direction.

[0010] In one of the technical solutions, a linear bearing is fixed to the side of the fixed seat facing away from the mounting seat, a guide rod is provided on the mounting seat, the guide rod passes through the linear bearing along the Z direction, and the elastic element is sleeved on the guide rod.

[0011] In one of the technical solutions, the mounting base has a plurality of limiting holes on the side facing away from the fixed base and corresponding to the position of each test head for limiting the position of the object to be tested. The distance between two adjacent limiting holes is the same as the distance between two adjacent test holes in each row of test areas, and part of the test head passes through the limiting holes.

[0012] In one of the technical solutions, the test head includes a positive test post and a negative test post, and each of the limiting holes is provided with the positive test post and the negative test post.

[0013] In one of the technical solutions, the semi-automatic resistance testing machine also includes a feeding mechanism;

[0014] The feeding mechanism is connected to the driving mechanism to move synchronously with the multi-channel test head. The feeding mechanism is signal-connected to the multi-channel test head and is used to automatically reject good or defective materials that have undergone resistance testing on the material tray.

[0015] In one of the technical solutions, the feeding mechanism includes a lifting device and a clamping device connected together. The lifting device is connected to the driving mechanism and is used to drive the clamping device to move up and down along the Z direction. The clamping device is used to clamp the good or defective materials on the material tray that have undergone resistance testing.

[0016] In one of the technical solutions, the lifting device is a lifting cylinder, and the clamping device is a gripper cylinder.

[0017] In one of the technical solutions, the driving mechanism includes a connected X-axis linear module and a Z-axis linear module, and several of the transfer mechanisms are Y-axis linear modules.

[0018] Compared with the prior art, the semi-automatic resistance tester provided by this utility model has at least the following beneficial effects:

[0019] In use, multiple test objects (such as e-cigarette cartridges) are first placed into the test holes of the tray by manual feeding. Then, the tray, which contains multiple rows of e-cigarette cartridges, is moved inward along the Y direction by the transfer mechanism to the bottom of the multi-channel test head. The multi-channel test head performs resistance tests on each row of e-cigarette cartridges under the drive mechanism. After the test is completed, the tray is moved outward along the Y direction by the transfer mechanism so that the tested e-cigarette cartridges can be manually removed and new e-cigarette cartridges to be tested can be loaded onto the tray. This solution can simultaneously perform resistance tests on multiple cartridges, thus significantly improving the efficiency of cartridge resistance testing. Furthermore, the solution incorporates several trays, and the multi-channel test head is specifically designed to move above these trays. This allows operators to use the time while the multi-channel test head is testing a cartridge in one tray to remove the tested material from other trays and refill them with cartridges awaiting testing. This enables the multi-channel test head to continuously perform resistance testing, further enhancing the efficiency of cartridge resistance testing. Attached Figure Description

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please refer to the following: Figures 1 to 3This utility model provides a semi-automatic resistance tester, mainly including a drive mechanism 1, a multi-channel test head 2, several transfer mechanisms 3, and several material trays 4. The material trays 4 have multiple rows of test areas 41, each row including multiple test holes 411. Each test hole 411 is used to place an object to be tested (in this embodiment, a cigarette cartridge is used as an example). The material trays 4 are connected one-to-one with the several transfer mechanisms 3. The transfer mechanism 3 drives a corresponding material tray 4 to move linearly along the Y-direction. The transfer mechanism 3 is preferably a Y-axis linear module, and can be a lead screw linear module, a linear motor module, or a synchronous belt linear module, etc. The multi-channel test head 2 is located on the material tray 4. Above, the drive mechanism 1 is connected to the multi-channel test head 2 and is used to drive the multi-channel test head 2 to move along the X and Z directions. The drive mechanism 1 preferably includes a connected X-axis linear module 11 and Z-axis linear module 12. The X-axis linear module 11 and Z-axis linear module 12 can be a lead screw linear module, a linear motor module, or a synchronous belt linear module, etc. The multi-channel test head 2 moves downward in the Z direction to test the resistance of multiple cartridges in one row of test areas 41. The range of the multi-channel test head 2 moving in the X direction includes above the two material trays 4, so that the multi-channel test head 2 can perform resistance testing on the cartridges in any material tray 4. This embodiment takes two transfer mechanisms 3 and two material trays 4 as an example.

[0033] Specifically, in use, multiple tobacco cartridges are first placed into the test holes 411 of the material tray 4 by manual feeding. Then, the material tray 4, which is loaded with multiple rows of tobacco cartridges, is moved inward along the Y direction by the transfer mechanism 3 to the bottom of the multi-channel test head 2. The multi-channel test head 2 performs resistance tests on each row of tobacco cartridges under the drive mechanism 1. After the test is completed, the material tray 4 is moved outward along the Y direction by the transfer mechanism 3 so that the tested tobacco cartridges can be manually removed and new tobacco cartridges to be tested can be loaded onto the material tray 4. This solution can simultaneously perform resistance tests on multiple tobacco cartridges, thus significantly improving the efficiency of tobacco cartridge resistance testing. Furthermore, the solution incorporates two trays 4, and specifically designs the multi-channel test head 2 to move above both trays 4. This allows the operator to use the time while the multi-channel test head 2 is testing a tobacco cartridge in one tray 4 to remove a tested tobacco cartridge from the other tray 4 and refill that tray with tobacco cartridges awaiting testing. This enables the multi-channel test head 2 to continuously perform resistance testing, further enhancing the efficiency of tobacco cartridge resistance testing.

[0034] Please refer to the following: Figures 1 to 3Multiple test areas 41 are arranged sequentially along the Y direction. Each row of test areas 41 includes multiple test holes 411 arranged sequentially along the X direction. The multi-channel test head 2 includes multiple test heads 21 arranged sequentially along the X direction. The spacing between two adjacent test heads 21 is the same as the spacing between two adjacent test holes 411 in each row of test areas 41, so that each test head 21 on the multi-channel test head 2 can correspond one-to-one with each test hole 411 in each row of test areas 41. That is, the multi-channel test head 2 can perform resistance testing on a row of e-cigarette cartridges at one time. In addition, when the material tray 4 moves along the Y direction under the drive of the transfer mechanism 3, any row of test areas 41 can move directly below the multi-channel test head 2, so that the multi-channel test head 2 can perform resistance testing on the e-cigarette cartridges in each row of test areas 41 sequentially. In fact, in this embodiment, the transfer mechanism 3 has two functions. The first function is to drive the material tray 4 to move back and forth between the external loading station and the internal testing station along a straight line in the Y direction, so that the manual can safely load the tobacco cartridges to be tested onto the material tray 4 from the outside away from the multi-way test head 2. The second function is to drive the material tray 4 to gradually feed along the Y direction so that the test head 21 can complete the resistance test on the tobacco cartridges on each row of test areas 41.

[0035] Please refer to the following: Figure 3 and Figure 4 The multi-channel test head 2 in this embodiment specifically includes a fixed base 22, a mounting base 23, an elastic element 24, and multiple test heads 21. The fixed base 22 is connected to the driving mechanism 1, which drives the entire multi-channel test head 2 to move by moving the fixed base 22. The mounting base 23 is located below the fixed base 22 and is slidably connected to it in the Z direction. The multiple test heads 21 are fixed to the mounting base 23 at intervals along the X direction. The elastic element 24 is preferably a spring, disposed between the fixed base 22 and the mounting base 23. When the mounting base 23 is subjected to the elastic force of the elastic element 24, it tends to move downwards away from the fixed base 22; that is, the mounting base 23 and the multiple test heads 21 tend to move downwards. This design of the multi-channel test head 2 allows the multiple test heads 21 to contact the cartridge in an elastic manner, avoiding the damage to the smoke channel or test heads 21 caused by hard-on contact, thus improving the reliability of the resistance test. Preferably, the multi-channel test head 2 of this embodiment further includes a linear bearing 25 and a guide rod 26. The guide rod 26 is fixed on the mounting base 23, and the linear bearing 25 is fixed on the side of the fixed base 22 facing away from the mounting base 23 (which can be understood as the linear bearing 25 being fixed on the top of the fixed base 22). The guide rod 26 passes through the linear bearing 25 along the Z direction to achieve the purpose of sliding connection between the mounting base 23 and the fixed base 22 in the Z direction. The elastic element 24 is preferably sleeved on the guide rod 26.

[0036] Please refer to them again. Figure 3 and Figure 4 The mounting base 23, facing away from the fixing base 22, has limiting holes 231 at the positions corresponding to each test head 21. In fact, the distance between two adjacent limiting holes 231 is the same as the distance between two adjacent test holes 411 in each row of test areas 41. A portion of the test head 21 passes through a corresponding limiting hole 231. This limiting hole 231 restricts the position of a test object (i.e., a cartridge), ensuring that the cartridge contacts the corresponding test head 21 only after being limited by the limiting hole 231. This ensures that the test head 21 can more accurately contact the electrodes on the cartridge, thereby improving the reliability of the multi-channel test head 2 in simultaneously testing a row of cartridges. Each test head 21 includes a positive test post 211 and a negative test post 212. When performing resistance testing on a cartridge, the positive test post 211 contacts the positive electrode of the cartridge, and the negative test post 212 contacts the negative electrode of the cartridge, thus allowing the resistance of the cartridge to be measured according to Ohm's law.

[0037] Please see Figure 3 The semi-automatic resistance tester in this embodiment also includes a feeding mechanism 5, which is connected to the drive mechanism 1. That is, the feeding mechanism 5 and the multi-channel test head 2 share a drive mechanism 1 and move synchronously. The feeding mechanism 5 and the multi-channel test head 2 are signal connected. When the multi-channel test head 2 measures the material as having good resistance or poor resistance, the feeding mechanism 5 can be used to remove the good or bad tobacco cartridges that have been tested on the material tray 4. Preferably, the feeding mechanism 5 is used to remove the bad tobacco cartridges, and the good tobacco cartridges are collected manually.

[0038] Please refer to it again. Figure 3 The feeding mechanism 5 specifically includes a lifting device 51 and a clamping device 52 connected together. The lifting device 51 is connected to the aforementioned drive mechanism 1 and is used to drive the clamping device 52 to move up and down along the Z direction. During operation, the clamping device 52, driven by the lifting device 51, clamps the good or defective e-cigarette cartridges that have undergone resistance testing on the material tray 4. Then, under the linkage drive of the drive mechanism 1 and the lifting device 51, the clamping device 52 can place the good or defective e-cigarette cartridges into the designated position. Preferably, the lifting device 51 is a low-cost lifting cylinder, and the clamping device 52 is preferably a low-cost gripper cylinder.

[0039] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
