Description

[0001] The utility model relates to the technical field of relay processing, in particular to an airtight leakage detection device for a relay. Background Art

[0002] A relay is an electronic control device that uses an electromagnet and a mechanical mechanism to control the switch of a circuit. When the input signal (such as voltage, current, or a signal of a specific frequency) changes, the relay will connect or disconnect its coil, thereby controlling one or more output circuits.

[0003] After the relay is produced, in order to ensure its production quality, it is necessary to complete the air tightness test of the relay through the testing equipment to determine whether there is any leakage;

[0004] The existing airtightness test is that personnel place the relay in a matching fixture to complete the test.

At the same time, during the test, personnel need to move around the device to complete the placement of the relay, and cannot achieve continuous advancement and transportation of the relay.

[0005] Therefore, the present application proposes a relay airtight leakage detection device. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] In order to solve the technical problems in the background technology, a relay airtight leakage detection device is provided as follows:

[0028] Combination Figure 1-Figure 5 As shown, a relay airtight leakage detection device provided by the utility model comprises a support platform 1, a mounting cover 6 is fixedly mounted on the top of the support platform 1, an airtight leakage detector 5 is arranged on the top of the mounting cover 6, a first cylinder 9 is fixedly mounted on the top of the mounting cover 6, a closing component 4 is docked and mounted on the output end of the first cylinder 9, a lower fixture 3 is assembled on the support platform 1 in the mounting cover 6, and the lower fixture 3 and the closing component 4 correspond to each other, a placement cavity 31 is arranged on the top of the lower fixture 3, and an ejection component 8 is assembled on the bottom of the placement cavity 31, mounting grooves 11 are arranged on the support platforms 1 on both sides of the mounting cover 6, and a conveying component 7 is assembled inside the mounting grooves 11;

[0029] During the operation, the personnel can place the material box loaded with relays on the conveying component 7, and the conveying component 7 has two effects during the operation. One is to keep the relay to be tested close to the personnel for picking up, and the other is to place and convey the relay after the test. In this way, the personnel only need to work at the work station without repeatedly moving around. The airtightness of the detection space can be detected in real time by cooperating with the detection probe in the closed component 4 through the airtight leakage detector 5. The closed component 4 and the lower fixture 3 can be docked by the first cylinder 9 to form a closed space and complete the detection of the relay. The ejection component 8 in the lower fixture 3 can cooperate with the personnel to place the relay to be tested. This can not only ensure the convenience of the personnel during placement, but also reduce the friction between the power terminal and the lower fixture 3 when the relay is placed. The closed component 4 and the ejection component 8 cooperate with each other to separate the detection space. This can not only realize the airtightness detection of multiple relays, improve the detection process, but also avoid detection interference.

[0030] The closing component 4 includes an upper fixture 41, an air intake component 42, an air pressure detection probe 43, and a partition plate 44. The output end of the first cylinder 9 is docked with an air intake chamber 411, the back of the upper fixture 41 is docked with an air intake component 42 extending into the air intake chamber 411, the front of the upper fixture 41 is docked with an air pressure detection probe 43 connected to the air intake chamber 411, and two groups of partition plates 44 are fixedly installed at the bottom of the upper fixture 41. The conveying component 7 includes a conveyor belt 71, and both sides of the top of the support platform 1 are provided with a mounting groove 11, and the interior of the mounting groove 11 is equipped with a conveyor belt 71; the ejection component 8 includes a placement plate 81, a mounting groove 2 82, and a spring 83. The bottom of the placement chamber 31 is provided with a docking port 32, and the bottom of the docking port 32 is docked with a spring 83 extending into the placement chamber 31, and the top of the spring 83 is fixedly installed with a placement plate 81, and the top of the placement plate 81 is fixedly installed with a mounting groove 2 82, and the mounting groove 2 82 cooperates with the partition plate 44;

[0031] During this period, the personnel placed the undetected relays on the conveyor belt 71 on the placement plate 81 in an orderly manner. The upper fixture 41 and the lower fixture 3 cooperated with each other to complete the docking. The partition plate 44 was tightly docked with the installation groove 82. At the same time, the placement plate 81 was compressed by the pressure spring 83 to form a closed space. At that time, the closed space was inflated through the air intake component 42. The personnel needed to set the corresponding inflation pressure value according to the volume of the relay first, and inflate and pressurize the relay first. When the pressure reached a sufficient level, the air source was disconnected to keep the internal pressure of the product stable and enter the stable pressure holding time. The internal pressure value of the closed space was sensed by the air pressure detection probe 43. When the pressure value continued to drop, it meant that the product had leakage. When the pressure value was stable, the product had no leakage. After completion, the inspected relays could be placed on another set of conveyor belts 71 for export.

The sensing component 2 includes an infrared receiver 21 and an infrared transmitter 22. The infrared receiver 21 and the infrared transmitter 22 are fixedly installed on both sides of the installation cover 6.

[0039] By combining the above contents, when the lower fixture 3 slides outward, the personnel can place the relay that needs to be tested;

[0040] When placing, the person's hand will be close to the lower fixture 3. At this time, the infrared receiver 21 and the infrared transmitter 22 are used to complete the detection of the person's hand. When the sensing information is received, the pushing device on the device enters the power-off state.

[0041] In this embodiment, a second cylinder 10 is fixedly installed on the rear side of the top of the support platform 1 , and an output end of the second cylinder 10 is installed and connected to the back side of the lower fixture 3 .

[0042] By combining the above contents, when the lower fixture 3 slides outward or inward, it is necessary to drive the second cylinder 10 to operate;

[0043] At that time, the second cylinder 10 can push the lower fixture 3 to perform reciprocating motion.

[0044] Embodiment 3

[0045] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0046] In this embodiment, the air intake component 42 includes a main pipe component 421, a branch pipe component 422, a docking joint 423, and an air valve 424.

[0047] During this period, the personnel need to first install and connect the joint 423 with the pipeline of the external inflation facility, and then complete the air guide operation of the main pipe 421, and then complete the inflation operation of the upper fixture 41 through the branch pipe 422 on the main pipe 421;

[0048] Before and after the inflation test, personnel can use the gas valve 424 to complete real-time control of the gas guiding process of the pipe.

[0049] In this embodiment, the conveying assembly 7 also includes a motor 72, and the conveyor belt 71 is composed of a conveyor roller and a guide belt.

[0050] During this period, when the material box is placed on the conveyor belt 71, the motor 72 can be started, and the output shaft of the motor 72 drives the conveyor belt 71 to convey, thereby completing the conveying operation of the material box;

[0051] It should be noted that the two sets of conveyor belts 71 are in reverse conveyance mode, one side conveys the untested relays to the personnel, and the other side conveys the tested relays for material lifting.

[0052] In this embodiment, the air inlet cavities 411 are grouped in pairs, and the partition plate 44 is located between each group of air inlet cavities 411 .

[0053] During this period, the air inlet cavity 411 corresponds to the placement cavity 31 below.
