Aging test device

Technical Field

Background

In real life, many electronic devices need to be powered by dry batteries, such as household remote controllers, wireless mice, VR (virtual reality) devices, AR (augmented reality) devices, MR (mixed reality) devices, and external temporary cardiac pacemakers. Before the electronic equipment leaves the factory and is put on the market, the aging test is needed, and the aging test is a test for the aging resistance of the electronic equipment under the environment of simulating factors causing the aging of the electronic equipment in the use of the electronic equipment.

The external temporary cardiac pacemaker is a microprocessor controlled cardiac intracavitary electrocardiosignal analyzing and pulse generating device, can sense the cardiac signal and deliver pacing pulse according to the requirement to maintain the basic cardiac electrical function of the patient, is used for preventing, diagnosing, protecting and emergency cardiac pacing, and can also be used for short-term synchronous or asynchronous cardiac pacing. As shown in fig. 1, the external temporary cardiac pacemaker 1 comprises a front plate 11, a rear shell 12 and a battery box 13, as shown in fig. 2 and 3, the battery box 13 is usually disposed on the rear shell 12, a conductive post 14 for electrically contacting a dry battery (not shown) is disposed inside the battery box 13, the conductive post 14 is fixed in the rear shell 12 via a spring 15 and a snap spring 16 and can be compressed within a certain stroke, wherein the snap spring 16 can limit the compression range of the spring 15, and then limit the moving stroke of the conductive post 14 at the end facing away from the dry battery. A limiting structure is arranged between the battery box 13 and the rear shell 12, and the assembled battery box 13 of the whole machine can only slide in the rear shell 12 but cannot be taken out. In normal operation, after the battery box 13 is loaded into a dry battery, the battery box 13 is pushed inwardly into the rear housing 12, the spring 15 on the conductive post 14 is compressed, and the conductive post 14 is fully contacted with the dry battery. At this time, the battery box 13 is tightly matched with the panel 11 and the rear shell 12, and the inner cavity of the product is sealed and completely isolated from the outside.

The external temporary cardiac pacemaker has high requirements on safety and effectiveness because the external temporary cardiac pacemaker is very likely to endanger the life safety of a patient once the external temporary cardiac pacemaker fails, and the external temporary cardiac pacemaker needs to be comprehensively and effectively tested in the production process of the external temporary cardiac pacemaker, for example, a complete machine power-on aging test lasting for nearly two hundred hours is required before the external temporary cardiac pacemaker leaves a factory so as to screen and eliminate the early failure risk of electronic components in the external temporary cardiac pacemaker. The existing scheme for the whole machine electrifying aging test of the external temporary cardiac pacemaker is that after the whole machine is assembled in a workshop, two dry batteries are arranged in a battery box and then the aging test is carried out, and the scheme has the following defects:

1. referring to fig. 1 to 3, the conductive post 14 of the external temporary cardiac pacemaker is fixed inside the rear case 12, and the battery box 13 cannot be removed, and a passage from the outside to the conductive post 14 through the battery box 13 is narrow and tortuous, so that the conventional forceps holder, probe and other connecting devices for aging test are not easily connected to the conductive post 14, and even if the connecting devices are connected to the conductive post 14, the connecting devices are not easily fixed and ensure effective power supply, thereby causing a risk of power failure in the middle of the test, and the power failure is not easily found in time, causing the test to be restarted after the test is found, and the efficiency is low;

2. because the test time span is long, nearly two hundred hours are required to be continuously carried out, and the electric quantity/service life of the dry battery is limited, the test has the risk of power failure in midway, the power failure is not easy to be found in time, the test needs to be restarted after the power failure is found, and the efficiency is low;

3. because the test time span is long, the test is required to be continuously carried out for nearly two hundred hours, and the electric quantity/service life of the dry battery is limited, the dry battery is greatly consumed, the cost is high, and the used scrapped battery can cause serious environmental pollution and damage.

In addition, the defects of the whole power-on aging test scheme of the in-vitro temporary cardiac pacemaker also exist in the whole power-on aging test of a plurality of electronic devices (such as household appliance remote controllers, wireless mice, VR devices, AR devices, MR devices and the like) which need to be powered by dry batteries, and also exist in the whole power-on aging test of a plurality of electronic devices (such as mobile phones and the like with openable back covers) which need to be powered by lithium batteries (replaceable).

In this embodiment, the test board 4 has a plurality of positioning cavities 420, the positioning cavities 420 have the same shape and size, and the number, the type, and the like of the analog batteries 43 disposed in each positioning cavity 420 are the same, so that the test board can be used for testing a batch of electronic devices of the same type. However, the technical solution of the present invention is not limited thereto, and in other embodiments of the present invention, the test board 4 may also be used to simultaneously test or time-share test a plurality of electronic devices with different required power voltage, and at this time, the voltage that can be provided by the positioning cavity 420 may be adjusted according to the difference of the electronic devices accommodated in the positioning cavity 420. In various embodiments of the present invention, how to specifically realize that the voltage provided at the positioning cavity 420 is adjustable may adopt one of the following (1) to (4):

(1) a transformer (not shown) connected to the lead 45 is disposed at each positioning cavity 420, and the transformer at each positioning cavity 420 is used for providing an adjustable voltage to each analog battery 43 at the positioning cavity 420, so that the voltage provided at the positioning cavity 420 can be adjusted. These transformers are all electrically connected to the power supply 3 by wires 45 at the location cavity 420, thereby meeting the test requirements of the electronic device 1 for different supply voltage requirements.

(2) A transformer (not shown) with a plurality of voltage output ports is disposed between the power source 3 and the test board 4, the voltage output ports of the transformer are detachably connected to the wires 45 at the positions of the positioning cavities 420, so that the voltage provided at the positions of the positioning cavities 420 can be adjusted, and different voltage output ports of the transformer output different direct current voltages to meet the test requirements of the electronic device 1 with different power supply voltage requirements. Specifically, for example, when the test board 4 has 3 positioning cavities 420, two 1.5V dry batteries are required to be mounted in the battery case 13 of the electronic device accommodated in the first positioning cavity 420, two analog batteries 43 connected in series can be arranged at the first positioning cavity 420, a battery box 13 of the electronic device 1 accommodated in the second positioning cavity 420 needs to be provided with 4 pieces of 1.5V dry batteries, the second positioning cavity 420 can be provided with 4 analog batteries 43 connected in series, the battery box 13 required by the electronic device 1 accommodated in the third positioning cavity 420 is required to be provided with 5 pieces of 1.5V dry batteries, the third positioning cavity 420 is provided with 5 analog batteries 43 connected in series, the transformer has at least three voltage output ports capable of outputting 3V, 6V and 7.5V, and the analog batteries 43 in the three positioning cavities 420 are connected in series and electrically connected to the corresponding voltage output ports of the transformer through corresponding wires 45.

(3) The analog battery 43 at each positioning cavity 420 is detachably disposed at the positioning cavity 420, so that the number of the analog batteries 43 at each positioning cavity 420 can be changed according to the electronic device 1 accommodated in the positioning cavity 420, and the voltage provided at the positioning cavity 420 can be adjusted. For example, 1 analog battery 43 is originally arranged at a certain positioning cavity 420, but 4 dry batteries are needed for the electronic device 1 accommodated in the positioning cavity 420, another 3 analog batteries 43 with the same type as the existing analog battery 43 can be arranged at the positioning cavity 420, and the 4 analog batteries 43 are all connected with the power supply 3 through the conducting wires 45, and the 4 analog batteries 43 are connected in series.

(4) The number of the analog batteries 43 already arranged in each positioning cavity 420 is fixed and is not less than 3 (e.g. 4, 5, 6 or 8), but there are how many of the analog batteries 43 need to be connected to the power supply, which depends on the requirement of the electronic device 1 accommodated in the positioning cavity 420, i.e. the number of the analog batteries 43 connected to the power supply 3 in each positioning cavity 420 can be changed according to the electronic device 1 accommodated in the positioning cavity 420. For example, if 1 analog battery 43 is originally arranged in one positioning cavity 420, but 4 dry batteries are needed for the electronic device 1 accommodated in the positioning cavity 420, another 3 analog batteries 43 with the same type as the existing analog batteries 43 can be arranged in the positioning cavity 420.

Alternatively, each of the positioning blocks 421 may be fixed on the test board 4 by, for example, integrally molding, screwing, or the like, so as to form the positioning cavity 420 with a fixed size, a fixed shape, and a fixed position, in which case, the burn-in tester can only test a fixed type of electronic device, and the manufacturing process and structure of the test board 4 can be simplified. Preferably, the positioning block 421 forming part or all of each positioning cavity 420 can be fixed after moving on the test board 4, so as to change the size and shape of the positioning cavity 420, so that one positioning cavity 420 can be used for testing different types of electronic devices having different shapes and/or different volumes, and at this time, the positioning block 421 forming part or all of each positioning cavity 420 can be shifted on the test board 4 by way of rail sliding or module insertion (like a rehearsal building block).

The position where the compression section 4352 meets the first electrode 4351 forms a first step 435a of the conductive rod 435, the first step 435a is a second limiting mechanism disposed on one end of the first electrode 4351 close to the fixed inner housing 432, the outer diameter of the first step 435a is not smaller than the inner diameter of the first end 4321 of the fixed inner housing 432 (for example, may be equal to the outer diameter of the first end 4321 of the fixed inner housing 432), and the first step 435a may limit the extreme moving position of one end of the first electrode 4351 close to the first end 4321 of the fixed housing 432 when the first electrode 4351 moves towards the second end of the fixed inner housing 432, so as to limit the maximum moving stroke of the first electrode 4351, prevent the first electrode 4351 from entering the fixed inner housing 432, and further prevent the first electrode 4351 from entering the inner cavity of the battery housing 431, thereby limiting the maximum moving stroke of the conductive rod 435 in the battery housing 431. The position where the compression section 4352 meets the second electrode 4353 forms a second step 435b of the conductive rod 435, the second step 435b is a first limiting mechanism arranged on the side of the elastic expansion mechanism 433 away from the first electrode 4351 and used for limiting the position of the elastic expansion mechanism 433 (i.e., a spring) close to one end of the first electrode 4351, and the second step 435b and the blocking piece 432c are matched, so that the elastic expansion mechanism 433 can be compressed in the direction away from the first electrode 4351 and cannot fall off from the conductive rod 435. The elastic expansion mechanism 433 can be compressed away from the first electrode 4351 after being pressed by the second step 435b, so that the first electrode 4351 can expand and contract relative to the battery housing 431, and the length of the dummy battery 43 can be adjusted.

The second electrode 4353 is provided with a locking groove 435c at a position corresponding to the stopping mechanism 434, when the dummy battery 43 is in a free state (i.e. placed in the battery box), the first electrode 4351 has a maximum extension length relative to the battery housing 431, the stopping mechanism 434 is locked in the locking groove 435c, and sufficient resistance can be provided to temporarily fix the position of the conductive rod 435, so as to prevent the conductive rod 435 from being separated from the battery housing 431 and leading to the scattering of the dummy battery 43 when the dummy battery 43 is subjected to unnecessary external force such as shaking, and when the dummy battery 43 needs to be placed in the battery box, the first electrode 4351 is pressed by a large force and moves in a direction close to the battery housing 431, so that the stopping mechanism 434 is separated from the locking groove 435c, and therefore, the conductive rod 435 can move relatively easily, and the dummy battery 43 can be quickly installed in the battery box.

The outer diameter and shape of the battery housing 431 are consistent with the actual battery simulated by the simulated battery 43, and then the battery housing can be loaded into the battery box 13 of the corresponding electronic device. Preferably, the length of the corresponding dummy battery 43 at each positioning cavity 420 in the non-compressed state is not less than the length of the dry battery (i.e. the actual battery) actually required by the battery box 13 installed in the positioning cavity 420, when the dummy battery 43 is installed in the battery box 13, the conductive rod 435 of the dummy battery 43 is automatically aligned with the conductive post 14 in the battery box 13, the elastic expansion mechanism 433 is compressed, the spring 15 in the rear case 12 is compressed, the conductive post 14 can be tightly contacted with the conductive rod 435, and the electronic device with the battery box 13 can be installed in place and firmly after being placed in the positioning cavity 420.
